$0.625 (the "Common Stock"), of UST Corp. ("UST"). The principal executive
offices of UST are located at 40 Court Street, Boston, Massachusetts 02109.

ITEM 2.           IDENTITY AND BACKGROUND.

         (a)-(c) and (f). This Schedule 13D is being filed by Citizens Financial
Group, Inc., a Delaware corporation and bank holding company ("CFG"). The
persons reporting information on this Schedule 13D include, in addition to CFG,
The Royal Bank of Scotland plc, a bank organized under the laws of the United
Kingdom and registered in Scotland (the "Royal Bank"), and The Royal Bank of
Scotland Group plc., a bank holding company organized in the United Kingdom and
registered in Scotland ("RBSG", and collectively with the Royal Bank and CFG,
the "Reporting Persons"). All of the stock of CFG is owned by the Royal Bank.
All of the stock of the Royal Bank is owned by RBSG.

         The executive offices of CFG are located at One Citizens Plaza,
Providence, Rhode Island 02903. The executive offices of the Royal Bank and RBSG
are each located at 42 St. Andrew Square, Edinburgh, Scotland EH2 2YE.

         CFG is one of the 50 largest bank holding companies in the United
States and one of the third largest in the New England region. Through its
subsidiaries, CFG offers a wide range of retail and corporate commercial banking
services, including residential and commercial mortgage lending and construction
loans, commercial loan and leasing services, trust services to businesses and
individuals, retail investment services and international banking services.

         The Royal Bank is a United Kingdom retail clearing bank with more than
700 branches throughout the United Kingdom, a branch office in New York City,
and an agency in San Francisco. The Royal Bank provides, through its
subsidiaries, an extensive range of banking, financial and finance related
services in a wide variety of markets in the United Kingdom and internationally.

         RBSG is a publicly owned financial services holding company

headquarters in Edinburgh, Scotland. The group is one of the 100 largest banking

range of banking, financial and finance-related services in the United Kingdom
and internationally.

         The names of the directors and executive officers of CFG and their
respective business addresses, citizenship, and present principal occupations or
employment and the names, principal business and address of any corporations or
other organizations in which such employment is conducted, are set forth in
Schedule I attached hereto, which Schedule I is specifically incorporated herein
by reference.

                               Page 5 of 12 Pages

<PAGE>

         The names of the directors and executive officers of the Royal Bank and
RBSG and their respective business addresses, citizenship, and present principal
occupations or employment and the names, principal business and address of any
corporations or other organizations in which such employment is conducted, are
set forth in Schedule II attached hereto, which Schedule II is specifically
incorporated herein by reference.

         (d)-(e). None of CFG, the Royal Bank, RBSG or, to the best of their
knowledge, any of the persons listed in Schedules I and II hereto, has during
the last five years been convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors) or has been a party to a civil proceeding of
a judicial or administrative body of competent jurisdiction and as a result of
such proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation of such laws.

ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATIONS.

         Pursuant to the Stock Option Agreement described in Item 4, UST has
granted CFG an option (the "Option") to purchase, upon the occurrence of certain
specified events which are not within the control of CFG, up to 8,541,333
authorized but unissued shares of Common Stock at a price of $24.25 per share,
which number of shares is subject to certain contingent anti-dilutive
adjustments (the "Option Shares"). The exercise of the Option to purchase the
full number of shares of Common Stock currently covered thereby would require
aggregate funds of $207,127,325.30, excluding administrative fees and expenses
associated therewith. In the event the Option becomes exercisable and CFG were
to purchase the Option Shares pursuant to the Stock Option Agreement, CFG
currently anticipates that such funds would be provided from working capital of
CFG and or Royal Bank and RBSG.

ITEM 4.           PURPOSE OF TRANSACTION.

         On June 21, 1999, CFG entered into an Agreement and Plan of Merger with
UST (the "Merger Agreement") pursuant to which a newly formed subsidiary of CFG
("Merger Sub") will be merged with and into UST (the "Merger"). UST will be the
surviving corporation of the Merger (the "Surviving Corporation") and, as a
result of and immediately following the Merger, will be a subsidiary of CFG.
Following the Merger, it is contemplated that UST will be liquidated into CFG.

         As a result of the Merger, each share of Common Stock issued and
outstanding immediately prior to the Effective Time (as such term is defined in
the Merger Agreement), excluding treasury shares, shall become and be converted
automatically into the right to receive in cash from CFG an amount equal to
$32.00. The cash consideration for each share of Common Stock is subject to
certain adjustments, as described in the Merger Agreement.

         Consummation of the Merger is subject to a number of conditions set
forth in the Merger Agreement, including without limitation, approval by the
requisite affirmative vote of the stockholders of UST, the receipt of regulatory
approvals, the absence of any order, injunction or decree issued by any court or
agency of competent jurisdiction or other legal

                               Page 6 of 12 Pages

<PAGE>

restraint or prohibition preventing the consummation of the Merger or any of the
other transactions contemplated by the Merger Agreement. If the Merger is
consummated as planned, the Common Stock will be de-registered pursuant to
Section 12(g)(4) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and cease to be listed on the NASDAQ National Market System.

         As an inducement to the willingness of CFG to enter into the Merger
Agreement, CFG and UST entered into a Stock Option Agreement, dated as of June
21, 1999 (the "Stock Option Agreement'). Pursuant to the Stock Option Agreement,
UST granted CFG the Option to purchase up to 8,541,333 authorized but unissued
shares of Common Stock at a price of $24.25 per share, which Option is
exercisable only upon the occurrence of certain events. The number of Option
Shares issuable upon exercise of the Option is subject to adjustment in the
event that any shares of Common Stock are issued or otherwise become outstanding
or are redeemed, repurchased, retired or otherwise cease to be outstanding after
the date of the Stock Option Agreement such that after such action the number of
Option Shares equals 19.9% of the number of shares of Common Stock then
outstanding without giving effect to any shares subject to or issued under the
Option. In addition, the number of shares subject to the Option will be adjusted
in the event of any change in the number of outstanding shares of Common Stock
by reason of any stock dividend, split-up, merger, recapitalization,
combination, subdivision, conversion, exchange of shares or the like by UST.
Under certain circumstances set forth in the Stock Option Agreement, UST can be
required to repurchase the Option and any Option Shares at a formula price based
on the difference between (x) the price paid or offered to be paid to UST or its
stockholders in certain competing transactions involving the acquisition of UST
or the highest last sale price of UST Common Stock within a defined period and
(y) the exercise price of the Option.

         Concurrently with the execution of the Merger Agreement, each of
certain directors and officers of UST (each, a "Stockholder," and collectively,
the "Stockholders") entered into a Stockholders Agreement with CFG
(collectively, the "Stockholders Agreements"), the form of which is attached
hereto as Exhibit 3. Pursuant to the Stockholders Agreements, the Stockholders
collectively have agreed to vote or cause to be voted an aggregate of 4,036,900
shares of Common Stock which are either held by such parties or which such
parties have rights to acquire, and any other shares of Common Stock
subsequently acquired by them (collectively, the "Voting Shares"), for the
approval of the Merger Agreement and the Merger and to vote or cause to be voted
the Voting Shares against the approval of any other agreement providing for a
merger, acquisition, consolidation, sale of a material amount of assets or other
business combination of UST or any of its subsidiaries with any person or entity
other than CFG or any of its subsidiaries. In addition, the Stockholders
Agreements also restrict the Stockholders' ability to sell, assign, transfer or
otherwise dispose of the Voting Shares.

         Pursuant to the Merger Agreement, unless otherwise provided by CFG, at
the Effective Time, the Articles of Organization of UST, as in effect at the
Effective Time, will be the Articles of Organization of the Surviving
Corporation and the By-Laws of Merger Sub, as in effect immediately prior to the
Effective Time, will be the By-Laws of the Surviving Corporation.

                               Page 7 of 12 Pages

<PAGE>

         The directors of Merger Sub immediately prior to the Effective Time
shall be the initial directors of the Surviving Corporation, each to hold office
in accordance with the Articles of Organization and By-laws of the Surviving
Corporation, and the officers of Merger Sub immediately prior to the Effective
Time shall be the initial officers of the Surviving Corporation, in each case
until their respective successors are duly elected or appointed and qualified.

         Except as set forth in this Item 4, the Merger Agreement, the Stock
Option Agreement, or the Stockholders Agreements, neither CFG, the Royal Bank
nor RBSG has any present plans or proposals that relate to or would result in
any of the actions specified in clauses (a) through (j) of Item 4 of this
Schedule 13D (although each such person reserves the right to develop such
plans).

         The preceding summary of certain provisions of the Merger Agreement,
the Stock Option Agreement, and the Stockholders Agreements is not intended to
be complete and is qualified in its entirety by reference to the full text of
such agreements in the Exhibits attached to this Schedule 13D.

ITEM 5.           INTEREST IN SECURITIES OF THE ISSUER.

         (a)-(b). Pursuant to Rule 13d-3(d)(1)(i) promulgated under the Exchange
Act, each of the Reporting Persons CFG, the Royal Bank and RBSG may be deemed
individually to own beneficially those amounts of shares of UST Common Stock
under the descriptions set forth below:


Sole Voting Power:                      8,541,333(1)

Shared Voting Power:                    4,036,900(2)

Sole Dispositive Power:                 8,541,333(1)

Shared Dispositive Power:               0

Aggregate  Beneficial Ownership:        12,578,233

Percentage of Class represented
by Aggregate Beneficial Ownership:      29.4%(3)

         Notes to Item 5(a)-(b).

         (1) By reason of the execution by CFG of the Stock Option Agreement (as
         described in Item 4 hereof), each of the Reporting Persons may be
         deemed to own beneficially 8,541,333 shares of Common Stock, which,
         following the issuance of such shares, would represent approximately
         19.9% of the outstanding shares of Common

                               Page 8 of 12 Pages

<PAGE>

         Stock reported by UST to the Reporting Persons as of June 21, 1999. If
         CFG were to acquire such Option Shares, each of the Reporting Persons
         would have sole voting and investment power with respect thereto.
         Because of the limited circumstances in which the Option is
         exercisable, each of the Reporting Persons expressly disclaims present
         beneficial ownership of the Option Shares pursuant to Rule 13d-4 under
         the Exchange Act.

         (2) By reason of the execution by CFG of the Stockholders Agreements
         (as described in Item 4 hereof), each of the Reporting Persons may be
         deemed to beneficially own 4,036,900 shares of Common Stock,
         constituting 9.5% of the outstanding shares of Common Stock as reported

         person in the Merger Agreement (as hereinafter defined), and (Y) the
         shares underlying the Option. The shares of Common Stock represented by
         the Option are 19.9% of the currently outstanding number of shares of
         Common Stock reported by UST to the Reporting Persons as of June 21,
         1999.

                  Except as set forth above or in a fiduciary capacity, no
Reporting Person nor, to the best of any Reporting Person's knowledge, any of
the individuals named in Schedules I and II hereto, owns any shares of Common
Stock.

                  (c) No Reporting Person nor, to the best of any Reporting
Person's knowledge, any of the individuals named in Schedule I and II hereto,

         WHEREAS, the Boards of Directors of the Buyer and the Seller have
determined that it is in the best interests of their respective stockholders and
other constituencies, as well as the communities they serve, to consummate, and
have approved, the business combination transactions provided for herein, in
which the Buyer will, subject to the terms and conditions set forth herein,

         WHEREAS, following the execution and delivery of this Agreement,
Citizens Bank of Massachusetts, a Massachusetts chartered stock savings bank and
subsidiary of the Buyer (the "Buyer Bank" and also sometimes referred to herein

         WHEREAS, the parties desire to make certain representations, warranties
and agreements in connection with the Merger and to prescribe certain conditions
to the Merger;

         NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained herein, and intending to be
legally bound hereby, the parties agree as follows:

                                        1

                                    ARTICLE I

                                   THE MERGER

         1.1 The Merger. Subject to the terms and conditions of this Agreement,
in accordance with the MBCL, at the Effective Time (as defined in Section 1.2
hereof), the Merger Sub shall merge with and into the Seller. The Seller shall
be the surviving corporation (hereinafter sometimes called the "Surviving
Corporation") in the Merger, and shall continue its corporate existence under
the laws of The Commonwealth of Massachusetts as a subsidiary of the Buyer. Upon
consummation of the Merger, the separate corporate existence of the Merger Sub
shall terminate.

         1.2 Effective Time. The Merger shall become effective as set forth in
the articles of merger (the "Articles of Merger") which shall be submitted for
filing to the Secretary of State of The Commonwealth of Massachusetts pursuant
to Section 78(a) of the MBCL on the Closing Date (as defined in Section 9.1
hereof). The term "Effective Time" shall be the date and time when the Merger
becomes effective, as set forth in the Articles of Merger.

         1.3 Effects of the Merger. At and after the Effective Time, the Merger
shall have the effects set forth in this Agreement and in Section 80 of the
MBCL.

         1.4 Conversion of Seller Common Stock. At the Effective Time, by virtue
of the Merger and without any action on the part of the Merger Sub, the Seller
or the holder of any of the shares of the Seller Common Stock (as defined
below):

         (a) Each share of the common stock, par value $0.625 per share, of the
Seller ("Seller Common Stock") issued and outstanding immediately prior to the
Effective Time (other than shares of Seller Common Stock held (x) in the
Seller's treasury or (y) directly or indirectly by the Buyer or the Seller or
any of their respective subsidiaries (except for Trust Account Shares and DPC
shares, as such terms are defined below) shall become and be converted
automatically into the right to receive in cash from the Buyer an amount equal
to $32.00 (the "Fixed Consideration"); provided, however, that:

                  (i) in the event that, (A) at any time prior to the Effective
         Time, the Buyer or any Affiliate of the Buyer submits a bid or other
         offer to acquire any assets or liabilities proposed to be divested in
         connection with the merger of Fleet Financial Group, Inc. and
         BankBoston Corporation (the "Branch Divestiture"), (B) the Effective
         Time does not occur on or prior to January 31, 2000, (C) the condition
         contained in Section 7.1(a) is satisfied and (D) the failure of the
         Effective Time to have occurred on or prior to January 31, 2000 is not
         attributable to acts or omissions by the Seller; then the Fixed
         Consideration shall be adjusted upwards by an amount determined by (1)
         multiplying (a) the Fixed Consideration by (b) 6%, rounded at the date
         the foregoing calculation is made at the Effective Time, to the nearest
         $.01, then (2) dividing the product determined pursuant to clause (1)
         by 365 and then (3) multiplying the amount obtained after the
         application of clauses (1) and (2) by the

                                        2

<PAGE>

         number of calendar days in the period commencing on February 1, 2000
         through and including the Closing Date; or alternatively,

                  (ii) in the event that, (A) prior to the Effective Time, the
         Buyer or any Affiliate of the Buyer does not submit a bid or other
         offer to acquire any assets or liabilities in the Branch Divestiture,
         (B) the Effective Time does not occur on or prior to February 29, 2000,
         (C) the condition contained in Section 7.1(a) is satisfied, and (D) the
         failure of the Effective Time to have occurred on or prior to February
         29, 2000 is not attributable to acts or omissions by the Seller; then
         the Fixed Consideration shall be adjusted upwards by an amount
         determined by (1) multiplying (a) the Fixed Consideration by (b) 6%,
         rounded at the date the foregoing calculation is made at the Effective
         Time, to the nearest $.01, then (2) dividing the product determined
         pursuant to clause (1) by 365 and then (3) multiplying the amount
         obtained after the application of clauses (1) and (2) by the number of
         calendar days in the period commencing on March 1, 2000 through and
         including the Closing Date.

The Fixed Consideration, to the extent adjusted as provided above, is referred
to herein as the "Merger Consideration."

         (b) All of the shares of Seller Common Stock converted into the Merger
Consideration pursuant to this Article I shall no longer be outstanding and
shall automatically be canceled and shall cease to exist as of the Effective
Time, and each certificate (each a "Certificate") previously representing any
such shares of Seller Common Stock shall thereafter represent the right to
receive the Merger Consideration. Certificates previously representing shares of
Seller Common Stock shall be exchanged for the Merger Consideration upon the
surrender of such Certificates in accordance with Section 2.2 hereof, without
any interest thereon.

         (c) At the Effective Time, all shares of Seller Common Stock that are
owned by the Seller as treasury stock and all shares of Seller Common Stock that
are owned directly or indirectly by the Buyer or the Seller or any of their
respective subsidiaries (other than shares of Seller Common Stock held directly
or indirectly in trust accounts, managed accounts and the like or otherwise held
in a fiduciary capacity that are beneficially owned by third parties (any such
shares, whether held directly or indirectly by the Buyer or the Seller, as the
case may be, being referred to herein as "Trust Account Shares") and other than
any shares of Seller Common Stock held by the Buyer or the Seller or any of
their respective subsidiaries in respect of a debt previously contracted (any
such shares of Seller Common Stock which are similarly held, whether held
directly or indirectly by the Buyer or the Seller or any of their respective
subsidiaries, being referred to herein as "DPC Shares")) shall be canceled and
shall cease to exist and no consideration shall be delivered in exchange
therefor.

         (d) Notwithstanding anything in this Agreement to the contrary, shares
of Seller Common Stock which are outstanding immediately prior to the Effective
Time, the holders of which shall have delivered to the Seller a written demand
for appraisal of such shares in

                                        3

<PAGE>

the manner provided in the applicable provisions of the MBCL ("Dissenting
Shares"), shall not be converted into the right to receive, or be exchangeable
for, the Merger Consideration otherwise payable in exchange for such shares of
the Seller Common Stock pursuant to this Section 1.4 but, instead, the holders
thereof shall be entitled to payment of the appraised value of such Dissenting
Shares in accordance with the provisions of the MBCL; provided, however, that
(i) if any holder of Dissenting Shares shall subsequently deliver a written
withdrawal of his demand for appraisal of such shares or (ii) if: any holder
fails to establish his entitlement to appraisal rights as provided in Sections
86 through 98 of the MBCL, such holder or holders (as the case may be) shall
forfeit the right to appraisal of such shares of Seller Common Stock and each of
such shares shall thereupon be deemed to have been converted into the right to
receive, and to have become exchangeable for, as of the Effective Time, the
Merger Consideration otherwise payable in exchange for such shares of Seller
Common Stock pursuant to this Section 1.4, without any interest thereon.

         (e) The Seller shall give the Buyer (i) prompt notice of any objections
filed pursuant to Sections 86 through 98 of the MBCL received by the Seller,
withdrawals of such objections, and any other instruments served in connection
with such objections pursuant to the MBCL and received by the Seller, and (ii)
the opportunity to direct all negotiations and proceedings with respect to
objections under the MBCL consistent with the obligations of the Seller
thereunder. The Seller shall not, except with the prior written consent of the
Buyer, (x) make any payment with respect to any such objection, (y) offer to
settle or settle any such objections or (z) waive any failure to timely deliver
a written objection in accordance with the MBCL.

         1.5 Merger Sub Common Stock. At and after the Effective Time, each
share of common stock, par value $.01 per share, of the Merger Sub issued and
outstanding immediately prior to the Effective Time shall become and be
converted automatically into one share of common stock of the Surviving
Corporation.

         1.6 Employee Stock Options. Prior to the Effective Time, the Seller
shall take all such action as is necessary to terminate The UST Corp. Stock

outstanding stock option to purchase shares of Seller Common Stock pursuant to
the Seller Stock Option Plans (whether or not such stock option is then vested
or exercisable), that such stock option shall be, as at the date of such notice,
exercisable in full and that such stock option shall terminate at the Effective
Time and that, if such stock option is not exercised or otherwise terminated
before the Effective Time, such holder shall be entitled to receive in
cancellation of such option a cash payment from the Seller at the Closing in an
amount equal to the excess of the

                                        4

<PAGE>

Merger Consideration over the per share exercise price of such stock option,
multiplied by the number of shares of Seller Common Stock covered by such stock
option, subject to any required withholding of taxes. Subject to the foregoing,
the Seller Stock Option Plans and all options issued thereunder shall terminate
at the Effective Time. The Seller hereby represents and warrants to the Buyer
that the maximum number of shares of Seller Common Stock subject to issuance
pursuant to the exercise of stock options issued and outstanding under the
Seller Stock Option Plans is not and shall not be at or prior to the Effective
Time more than 2,386,818.

         1.7 Articles of Organization. Unless otherwise provided by the Buyer,
at the Effective Time, the Articles of Organization of the Seller, as in effect
at the Effective Time, shall be the Articles of Organization of the Surviving
Corporation until thereafter amended in accordance with applicable law.

         1.8 By-Laws. At the Effective Time, the By-Laws of the Buyer, as in
effect immediately prior to the Effective Time, shall be the By-Laws of the

Corporation, each to hold office in accordance with the Articles of Organization
and By-laws of the Surviving Corporation, and the officers of Merger Sub
immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, in each case until their respective successors are duly

                               EXCHANGE OF SHARES

         2.1 Buyer to Deposit Aggregate Merger Consideration. At or prior to the
Effective Time, the Buyer shall pay, or shall cause to be paid, to a bank or
trust company selected by the Buyer and reasonably acceptable to the Seller
(which may be a subsidiary or other Affiliate of the Buyer) (the "Exchange
Agent"), for the benefit of the holders of Certificates, for exchange in
accordance with this Article II, such amount of cash as is sufficient to pay the
aggregate Merger Consideration which holders of Seller Common Stock are entitled
to receive pursuant to Section 1.4 hereof.

         2.2      Exchange of Shares.

         (a) As soon as practicable after the Effective Time, and in no event
later than two business days thereafter, the Buyer shall cause the Exchange
Agent to mail to each holder of record of a Certificate or Certificates a form
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent) and instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration into
which the shares

                                        5

<PAGE>

of Seller Common Stock represented by such Certificate or Certificates shall
have been converted pursuant to this Agreement. Upon proper surrender of a
Certificate for exchange and cancellation to the Exchange Agent, together with
such properly completed letter of transmittal, duly executed, the holder of such
Certificate shall be entitled to receive in exchange therefor, the Merger
Consideration, and the Certificate so surrendered shall forthwith be canceled.
No interest shall accrue or be paid on the Merger Consideration payable upon the
surrender of any Certificate for the benefit of the holder of such Certificate.
If payment of the Merger Consideration is to be made to a person other than the
person in whose name the surrendered Certificate is registered on the stock
transfer books of the Seller, it shall be a condition of payment that the
Certificate so surrendered shall be endorsed properly or otherwise be in proper
form for transfer and that the person requesting such payment shall have paid
all transfer and other taxes required by reason of the payment of the Merger
Consideration to a person other than the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such taxes either have been paid or are not applicable.

         (b) At any time following the sixth month after the Effective Time, the
Buyer or the Surviving Corporation shall be entitled to require the Exchange
Agent to deliver to it any funds which had been made available to the Exchange
Agent and not disbursed to holders of shares of Seller Common Stock (including,
without limitation, all interest and other income received by the Exchange Agent
in respect of all funds made available to it), and thereafter such holders shall
be entitled to look to the Buyer and the Surviving Corporation only as general
creditors thereof with respect to any Merger Consideration that may be payable
upon due surrender of the Certificates held by them.

         (c) After the Effective Time, there shall be no transfers on the stock
transfer books of the Seller of the shares of Seller Common Stock which were
issued and outstanding immediately prior to the Effective Time. From and after
the Effective Time, the holders of shares of Seller Common Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares except as otherwise provided herein or by applicable law.
If, after the Effective Time, Certificates representing such shares are
presented for transfer to the Exchange Agent, they shall be canceled and
exchanged for the Merger Consideration as provided in this Article II.

         (d) Neither the Buyer nor the Seller nor any other person shall be
liable to any former holder of shares of Seller Common Stock for any shares or
any dividends or distributions with respect thereto or any Merger Consideration
delivered in respect of any such shares properly delivered to a public official
pursuant to applicable abandoned property, escheat or similar laws.

         (e) In the event any Certificate shall have been lost, stolen or
destroyed, upon receipt of appropriate evidence as to such loss, theft or
destruction and to the ownership of such Certificate by the person claiming such
Certificate to be lost, stolen or destroyed, and the receipt by the Buyer of
appropriate and customary indemnification, the Buyer will issue

                                        6

<PAGE>

in exchange for such lost, stolen or destroyed Certificate, the Merger
Consideration, as determined in accordance with this Article II.

standing in each jurisdiction in which the nature of the business conducted by

         4.8 Legal Proceedings. There is no claim, suit, action, proceeding or
investigation of any nature pending or, to the best knowledge of the Seller,
threatened, against the Seller or any subsidiary of the Seller or challenging

Material Adverse Effect on the Seller or otherwise materially adversely affect
the Seller's or the Seller Bank's ability to perform its obligations under this
Agreement or the Bank Merger Agreement, nor is there any judgment, decree,
injunction, rule, award or order of any legal or administrative body or
arbitrator outstanding against the Seller or any subsidiary of the Seller
having, or which insofar as reasonably can be foreseen, in the future could

the Seller nor any of its subsidiaries is a party to any agreement or
arrangement entered into in connection with the consummation of a federally
assisted acquisition of a depository institution pursuant to which the Seller or
any of its subsidiaries is entitled to receive financial assistance or

         4.11 Absence of Undisclosed Liabilities. Except for those liabilities
that are fully reflected or reserved against on the Seller Balance Sheet and for
liabilities incurred in the ordinary course of business consistent with past
practice, since December 31, 1998, neither the Seller nor any of its
subsidiaries has incurred any obligation or liability (contingent or otherwise)
that, either alone or when combined with all similar liabilities, has had, or
could reasonably be expected to have, a Material Adverse Effect on the Seller.

         4.12 Compliance with Applicable Law. Each of the Seller and each
Significant Subsidiary thereof holds all material licenses, franchises, permits
and authorizations necessary for the lawful conduct of its business, and each of

statute, order, rule, regulation or policy of, or agreement with, any federal,
state or local governmental agency or authority relating to the Seller or such
Significant Subsidiary, other than where such default or noncompliance will not
result in, or create the possibility of resulting in any Material Adverse Effect
on the Seller or any Significant Subsidiary of the Seller, and neither the
Seller nor any Significant Subsidiary of the Seller has received any notice of
any violation of any such law, statute, order, rule, regulation, policy or
agreement, or commencement of any proceeding in connection with any such

regulation, policy or agreement which would have such a result.

         4.13 Taxes and Tax Returns. Except as set forth in Section 4.13 of the
Disclosure Schedule:

         (a) Except where the failure to do so would not have a Material Adverse
Effect on the Seller Companies as a whole, the Seller and each of its
subsidiaries (referred to for purposes of this Section 4.13, collectively, as
the "Seller Companies") have, since December 31, 1992, timely filed in correct
form all Tax Returns that were required to be filed by any of them on or prior
to the date hereof (the "Filed Tax Returns"), and have paid all Taxes shown as
being due thereon.

         (b) No assessment that has not been settled or otherwise resolved has
been made with respect to Taxes not shown on the Filed Tax Returns, other than
such additional Taxes as are being contested in good faith or which if
determined adversely to the Seller Companies would not have a Material Adverse
Effect on the Seller Companies as a whole. The Income Tax Returns of the Seller
Companies have been examined by the Internal Revenue Service ("IRS") or other
taxing authority, as applicable, for all years through 1994 and any liability
with respect thereto has been satisfied. There are no material disputes pending
or written claims asserted for Taxes or assessments upon any Seller Company, nor
has any Seller Company been requested to give any currently effective waivers
extending the statutory period of limitation applicable to any Federal, state,
county or local income tax return for any period. No deficiency in Taxes or
other proposed adjustment that has not been settled or otherwise resolved has
been asserted in writing by any taxing authority against any of the Seller
Companies, which if determined adversely to the Seller Companies would have a
Material Adverse Effect on the Seller Companies as a whole. No material Tax
Return of any of the Seller Companies is now under examination by any applicable
taxing authority. There are no material liens for Taxes (other than current
Taxes not yet due and payable) on any of the assets of any Seller Company,
except for such liens for Taxes that would not have a Material Adverse Effect on
the Seller Companies as a whole.

         (c) Adequate provision has been made on the Seller Balance Sheet for
all Taxes of the Seller Companies in respect of all periods through the date
hereof.

         (d) Except with respect to intra-Seller Company agreements made or

Seller Companies is a party to or bound by any Tax indemnification, Tax
allocation or Tax sharing agreement with any person or entity or has any current
or potential contractual obligation to indemnify any other person or entity with
respect to Taxes.

         (e) None of the Seller Companies has filed or been included in a
combined, consolidated or unitary income Tax Return (including any consolidated
federal income Tax Return) other than one of which one of the Seller Companies
was the parent.

any of its subsidiaries. No employees of the Seller or any of its subsidiaries
are represented by any labor union, and, to the best knowledge of the Seller's

factors that would apply if that plan terminated in accordance with all
applicable legal requirements.

or circumstance which would adversely affect the qualified status of any such
plan.

         (g) The Seller has made or provided for all contributions to the Seller

no other material correspondence between the Seller and any Governmental
Authority related to any other Seller Benefit Plan.

         4.16 Capitalization. The Seller and each of the subsidiaries of the
Seller which are "insured depository institutions" are "adequately capitalized"
as such term is defined in the rules and regulations promulgated by the Federal
Reserve Board and the FDIC.

at the Effective Time or at a date thereafter, non-renewal of personal property
leases and software licenses used by the Seller or any of its subsidiaries in
connection with its systems operations, retention of outside consultants and

and its subsidiaries for any such fees, expenses and charges, and the costs of

the terms of this Agreement. No action taken by the Seller or the Seller Bank
pursuant to this Section or the consequences resulting therefrom shall be deemed
to be a breach of any representation, warranty, agreement or covenant herein or
constitute a Material Adverse Effect. In the event that the Seller or any of its
subsidiaries takes, at the request of the Buyer, any action pursuant to this
Section 5.5, the Buyer shall indemnify the Seller and its subsidiaries for any
fees, expenses and charges, and the costs of reversing the action taken, if for
any reason the Merger is not consummated in accordance with the terms of this

Bank to prepare and file applications for branch closings with all appropriate
Bank Regulators after all of the Requisite Regulatory Approvals have been

the

                                       33

<PAGE>

Merger is not consummated in accordance with the terms of this Agreement, the
Buyer will reimburse the Seller for any fees or expenses incurred in connection
with the preparation and filing of such applications at the request of the
Buyer.

         5.7 Servicing. The Seller agrees that upon the expiration of any of the
Seller's or its subsidiaries' 401(k) servicing agreements prior to the Closing,
it will enter into a new 401(k) servicing agreement with the same service
provider as the Buyer, provided, however, that the Seller or its subsidiaries
shall not be obligated to do so unless the terms of such new agreement are
comparable to or not materially less favorable than terms then available to the
Seller. If requested by the Buyer, the Seller shall, and shall cause certain of
its subsidiaries to, provide notices of termination with respect to certain
other servicing arrangements of the Seller or its subsidiaries existing as of
the date hereof; provided, however, that, if for any reason the Merger is not
consummated in accordance with the terms of this Agreement, the Buyer shall
indemnify the Seller and its subsidiaries for any fees, expenses, charges, and
the costs of reversing the action taken or entering into a new servicing
agreement on terms substantially similar to the servicing arrangements so
terminated pursuant to this Section 5.7.

         5.8 Medford Operations Facility. From and after the date hereof, the
Buyer and the Seller shall consult and cooperate with each other with respect to
the completion of the building of the Seller's Medford operations facility and
the parties shall use their reasonable best efforts to continue utilizing for

Seller as of the date hereof; provided, however, that the Seller shall not enter
into any new commitments with respect to capital expenditures on such facility
without the consent of the Buyer; provided, further, that in the event that the
Merger is not consummated in accordance with the terms of this Agreement, at the
Seller's option, within thirty (30) days of the Seller's written request, the
Buyer shall purchase the Medford operations facility from the Seller at a cash
purchase price equal to the net book value of such facility as of the date of
purchase and upon such other terms and conditions as are conventional for the
sale of similar commercial real estate.


                                   ARTICLE VI

                              ADDITIONAL AGREEMENTS

         6.1      Regulatory Matters; Consents.

         (a) The Seller will as promptly as practicable, take all steps
necessary to duly call, give notice of, convene and hold a meeting of its
stockholders (the "Seller Stockholders Meeting") to be held as soon as possible
following clearance by the SEC of the Seller Proxy Statement, for the purpose of
approving this Agreement and the Merger.

         (b) The Seller's Board of Directors has adopted a resolution
recommending approval and adoption of this Agreement and the Merger by the
Seller's stockholders, and except as provided in the next sentence, the Board of
Directors of the Seller shall at all times

                                       34

<PAGE>

recommend approval and adoption of this Agreement and the Merger by the Seller's
stockholders. The Board of Directors of the Seller shall be permitted to
withdraw or modify in a manner adverse to the Buyer (or not to continue to make)
its recommendation to its stockholders if, but only if, (a) in the opinion of
the Seller's outside counsel, such action is required, in response to an
unsolicited bona fide written Superior Proposal, in order for the Board of
Directors of the Seller to comply with its fiduciary duties under applicable
law, (b) the Seller has given the Buyer five (5) business days' prior notice of
the receipt of such Superior Proposal and the Seller's Board of Directors has
considered any proposed changes to this Agreement (if any) proposed by the
Buyer, and (c) the Seller has fully and completely complied with Section 6.2
hereof. For the purposes of this Agreement, "Superior Proposal" shall mean any
bona fide Acquisition Transaction for at least a majority of the outstanding
shares of the Seller Common Stock on terms the Board of Directors of the Seller
determines in its good faith judgment (taking into account the advice of a
financial advisor of nationally recognized reputation, taking into account all
the terms and conditions of the Acquisition Transaction, including any break-up
fees, expense reimbursement provisions and conditions to consummation) are in
the aggregate more favorable and provide greater value to all the Seller's
stockholders than this Agreement and the Merger taken as a whole. For purposes
of this Agreement, "Acquisition Transaction" means any offer or proposal for, or
any indication of interest in (w) a merger or consolidation, or any similar
transaction, involving the Seller or any Significant Subsidiary of the Seller,
(x) a purchase, lease or other acquisition or assumption of all or a substantial
portion of the assets or deposits of the Seller or all or substantially all of
the assets or deposits of any Significant Subsidiary of the Seller, (y) a
purchase or other acquisition (including by way of merger, consolidation, share
exchange or otherwise) of beneficial ownership (the term "beneficial ownership"
for purposes of this Agreement having the meaning assigned thereto in Section
13(d) of the Exchange Act, and the rules and regulations thereunder) of
securities representing 10% or more of the voting power of the Seller or more
than 25% of any Significant Subsidiary of the Seller, or (z) any substantially
similar transaction.

         (c) As soon as practicable after the date hereof, and in any event by
July 15, 1999, the Seller shall prepare and file the Seller Proxy Statement with
the SEC under the Exchange Act and shall use its reasonable best efforts to have
the Seller Proxy Statement cleared by the SEC. The Buyer and the Seller shall
cooperate with each other in the preparation of the Seller Proxy Statement and
the Seller shall notify the Buyer promptly of the receipt of any comments of the
SEC with respect to the Seller Proxy Statement and of any requests by the SEC
for any amendment or supplement thereto or for additional information and shall
provide to the Buyer promptly copies of all correspondence between the Seller or
any representative of the Seller and the SEC. The Seller shall give the Buyer
and its counsel the opportunity to review the Seller Proxy Statement prior to
its being filed with the SEC and shall give the Buyer and its counsel the
opportunity to review all amendments and supplements to the Seller Proxy
Statement and all responses to requests for additional information and replies
to comments prior to their being filed with, or sent to, the SEC. Each of the
Buyer and the Seller agrees to use its reasonable best efforts, after
consultation with the other party hereto, to respond promptly to all such
comments of and

                                       35

requests by the SEC and to cause the Seller Proxy Statement and all required
amendments and supplements thereto to be mailed to the holders of Seller Common
Stock entitled to vote at the Seller Stockholders Meeting referred to in Section
6.1(a) hereof at the earliest practicable time.

         (d) The parties hereto shall cooperate with each other and use their
reasonable best efforts to promptly prepare and file all necessary
documentation, to effect all applications, notices, petitions and filings, to
obtain as promptly as practicable all permits, consents, approvals and
authorizations of all third parties and Governmental Authorities which are
necessary or advisable to consummate the transactions contemplated by this
Agreement (including, without limitation, the Merger and the Bank Merger), and
to comply with the terms and conditions of all such permits, consents, approvals
and authorizations of all such Governmental Authorities. The Buyer and the
Seller shall have the right to review in advance, and, to the extent
practicable, each will consult the other on, in each case subject to applicable
laws relating to the exchange of information, all the information relating to
the Buyer or the Seller, as the case may be, and any of their respective
subsidiaries, which appear in any filing made with, or written materials
submitted to, any third party or any Governmental Authority in connection with
the transactions contemplated by this Agreement. In exercising the foregoing
right, each of the parties hereto shall act reasonably and as promptly as
practicable. The parties hereto agree that they will consult with each other
with respect to the obtaining of all permits, consents, approvals and
authorizations of all third parties and Governmental Authorities necessary or
advisable to consummate the transactions contemplated by this Agreement and each
party will keep the other apprised of the status of matters relating to
completion of the transactions contemplated herein.

         (e) The Buyer and the Seller shall, upon request, furnish each other
with all information concerning themselves, their subsidiaries, directors,
officers and stockholders and such other matters as may be reasonably necessary
or advisable in connection with the Seller Proxy Statement or any other
statement, filing, notice or application made by or on behalf of any Affiliate
of the Buyer, the Buyer or the Seller or any of their respective subsidiaries to
any Governmental Authority in connection with the Merger, the Bank Merger and
the other transactions contemplated by this Agreement.

         (f) The Buyer and the Seller shall promptly advise each other upon
receiving (and the Buyer shall so advise with respect to communications received
by any Affiliate of the Buyer) any communication from any Governmental Authority
whose consent or approval is required for consummation of the transactions
contemplated by this Agreement that causes such party to believe that there is a
reasonable likelihood that any Requisite Regulatory Approval will not be
obtained or that the receipt of any such approval will be materially delayed.

         6.2 No Solicitation. Unless and until this Agreement shall have been
properly terminated by either party pursuant to Section 8.1 hereof, neither the
Seller nor any of its subsidiaries or Affiliates shall (and the Seller shall use
its reasonable best efforts to cause its

                                       36

<PAGE>

representatives, including, but not limited to, investment bankers, attorneys
and accountants, not to), directly or indirectly, encourage, solicit, initiate
or take any action to facilitate, any inquires or the making of an offer or
proposal regarding, or participate in any discussions or negotiations with, or
provide any information to, any Person (other than the Buyer and its Affiliates
or representatives), concerning any Acquisition Transaction provided, that the
Seller may, in response to an unsolicited written offer or proposal regarding an
Acquisition Transaction, furnish non-public information with respect to the
Seller and its subsidiaries to the third party making such written offer or
proposal and may participate in negotiations regarding such written offer or
proposal if (A) the Seller's Board of Directors determines in good faith based
on the written advice of outside counsel of the Seller that such action is
required for the Seller's Board of Directors to comply with the fiduciary duties
applicable to directors under applicable law and (B) the Seller has received
from such third party an executed confidentiality agreement with terms not
materially less favorable to the Seller than those contained in the
Confidentiality Agreement with the Buyer. Notwithstanding the foregoing, nothing
contained in this Section 6.2 shall prohibit the Seller or its Board of
Directors from taking and disclosing to the Seller's stockholders a position
with respect to a tender offer by a third party pursuant to Rules 14d-9 and
14e-2(a) promulgated under the Exchange Act or from making such disclosure to
the Seller's stockholders which, in the judgment of the Board of Directors as
determined in good faith and as advised in writing by outside counsel, may be
required under applicable law. The Seller will immediately communicate to the
Buyer the terms of any proposal, discussion, negotiation or inquiry relating to
an Acquisition Transaction and the identity of the party making such proposal or
inquiry which it may receive in respect of any such transaction (which shall
mean that any such communication shall be delivered no less promptly than by
telephone within 24 hours of the Seller's receipt of any such proposal or
inquiry) or its receipt of any request for information from the Federal Reserve
Board, the DOJ, or any other Governmental Authority with respect to a proposed
Acquisition Transaction. The Seller agrees not to release any third party from,
or waive any provision of, any confidentiality or standstill agreement to which
the Seller or the Seller Bank is a party regarding an Acquisition Transaction.

         6.3      Access to Information.

         (a) Upon reasonable notice and subject to applicable laws relating to
the exchange of information, each of the Buyer and the Seller, for the purposes
of verifying the representations and warranties of the other and relating to the
Merger and the other matters contemplated by this Agreement, shall, and shall
cause each of their respective subsidiaries to, afford to the officers,
employees, accountants, counsel and other representatives of the other party,
access, during normal business hours during the period prior to the Effective
Time, to all its properties, books, contracts, commitments and records, and,
during such period, each of the Buyer and the Seller shall, and shall cause
their respective subsidiaries to, make available to the other party (i) a copy
of each report, schedule, registration statement and other document filed or
received by it during such period pursuant to the requirements of federal
securities laws or federal or state banking laws (other than reports or
documents which the Buyer or the Seller, as the case may be, is not permitted to
disclose under

                                       37

<PAGE>

applicable law) and (ii) all other information concerning its business,
properties and personnel as such party may reasonably request. Neither the Buyer
nor the Seller nor any of their respective subsidiaries shall be required to
provide access to or to disclose information where such access or disclosure
would violate or prejudice the rights of the Buyer's or the Seller's, as the
case may be, customers, jeopardize the attorney-client privilege of the
institution in possession or control of such information or contravene any law,
rule, regulation, order, judgment, decree, fiduciary duty or binding agreement
entered into prior to the date of this Agreement. The parties hereto will make
appropriate substitute disclosure arrangements under circumstances in which the
restrictions of the preceding sentence apply.

         (b) All information furnished by any party hereto to the other or its
representatives pursuant hereto shall be treated as the sole property of the
party providing the information and, if the Merger shall not occur, the party
being furnished such information shall return to the other party all of such
written information and all documents, notes, summaries or other materials
containing, reflecting or referring to, or derived from, such information. The
parties hereto shall, and shall use their reasonable best efforts to cause their
representatives to, keep confidential all such information, and shall not
directly or indirectly use such information for any competitive or other
commercial purpose. The obligation to keep such information confidential shall
continue for five years from the date the proposed Merger is abandoned and shall
not apply to (i) any information which (x) was already in the possession of the
party being furnished such information prior to the disclosure thereof by the
other party, (y) was then generally known to the public, or (z) was disclosed to
the party being furnished such information by a third party not bound by an
obligation of confidentiality; or (ii) disclosures made as required by law.

         (c) No investigation by either of the parties or their respective
representatives shall affect the representations and warranties of the other set
forth herein.

         6.4 Legal Conditions to Merger. Each of the Buyer and its Affiliates
and the Seller shall, and the Seller shall cause its subsidiaries to, use their
reasonable best efforts (a) to take, or cause to be taken, all actions
necessary, proper or advisable to comply promptly with all legal requirements
that may be imposed on such party or its subsidiaries with respect to the Merger
and, subject to the conditions set forth in Article VII hereof, to consummate
the transactions contemplated by this Agreement, and (b) to obtain (and to
cooperate with the other party to obtain) any material consent, authorization,
order or approval of, or any exemption by, any Governmental Authority and any
other third party that is required to be obtained by the Buyer or the Seller or
any of their respective subsidiaries in connection with the Merger, the Bank
Merger and the other transactions contemplated by this Agreement.

         6.5      Employment and Benefit Matters.

         (a) From and after the Effective Time, the Buyer agrees to provide the
employees of the Seller and its subsidiaries (the "Seller Employees") who remain
employed after the Effective Time (collectively, the "Transferred Seller
Employees") with the types and levels

                                       38

<PAGE>

of employee benefits maintained by the Buyer for similarly situated employees of
the Buyer. The Buyer will treat, and cause its applicable benefit plans to
treat, the service of Seller Employees with Seller or any subsidiary of Seller
as service rendered to the Buyer or any Affiliate of Buyer for purposes of
eligibility to participate, vesting and for other appropriate benefits
including, but not limited to, applicability of minimum waiting periods for
participation, but not for benefit accrual (including minimum pension amount)
attributable to any period before the Effective Time. Without limiting the
foregoing, the Buyer shall not treat any employee of the Seller or any of its
subsidiaries as a "new" employee for purposes of any exclusions under any health
or similar plan of the Buyer for a pre-existing medical condition, and will make
appropriate arrangements with its insurance carrier(s) to ensure such result.

         (b) Compensation Arrangements. Following the Effective Time, the Buyer
shall honor and shall cause its subsidiaries to honor in accordance with their
terms all individual employment, termination, severance, change in control,
post-employment and other compensation agreements, arrangements and plans
existing prior to the execution of this Agreement, which are between the Seller
or any subsidiary of the Seller and any director, officer or employee thereof,
and the Buyer will not, and will not cause any of its subsidiaries to, challenge
the validity of any obligation of the Seller or any subsidiary of the Seller
under, any employment, severance, change in control, post-employment,
consulting, supplemental retirement or such other compensation, contract or
arrangement with any current or former director, officer or employee of the
Seller. Notwithstanding the terms of this Agreement or any plan to the contrary,
prior to the Effective Time, the Seller shall be permitted to cause one or more
trusts to be formed and to fund such trusts, the purpose of which will be to
fund all obligations which may be payable after the Effective Time to employees
of the Seller under the Seller's Senior Executive Plan and such other plans of
the Seller set forth in Section 6.5(b) of the Seller Disclosure Schedule.

         (c) Continuation of Plans. Notwithstanding anything to the contrary
contained herein, the Buyer shall have sole discretion with respect to the
determination as to whether or when to terminate, merge or continue any employee
benefit plans and programs of the Seller; provided, however, that the Buyer
shall continue to maintain the Seller plans (other than stock based or incentive
plans or stock funds in retirement plans) until the Seller Employees are
permitted to participate in the Buyer's plans. Nothing in this Agreement shall
alter or limit the Buyer's obligations, if any, under ERISA, as amended by the
Consolidated Omnibus Budget Reconciliation Act of 1985 and/or the Health
Insurance Portability and Accountability Act of 1996 with respect to the rights
of Seller Employees and their qualified beneficiaries in connection with the
group health plan maintained by the Seller as of the Effective Time.

         (d) Severance Obligations. For a period of one (1) year after the
Closing Date, the Buyer will provide all Seller Employees who are not otherwise
covered by a specific termination, severance or change in control agreement with
a severance plan with provisions which are at least as favorable in the
aggregate to any Seller Employee whose employment

                                       39

<PAGE>

is terminated after the Effective Time as the severance plan or policy currently
maintained by the Seller or any Seller subsidiary for such employee as disclosed
in Section 4.15(a) of the Seller Disclosure Schedule. Any Seller Employee whose
position is terminated on or prior to the Effective Time shall be entitled to
severance benefits in accordance with the severance plan or policy currently
maintained by the Seller or any subsidiary of the Seller for such employee.

         (e) The provisions of this Section 6.5 respecting the Buyer's agreement
to honor the contracts, arrangements, commitments and understandings referred to
in Section 6.5(b) are intended to be for the benefit of and enforceable by the
persons referred to therein or the parties to these agreements, respectively,
and their heirs and representatives.

         (f) Notwithstanding anything to the contrary contained in this
Agreement, in no event shall the Seller or any of its subsidiaries take any
action or make any payments that would result, either individually or in the
aggregate, in the payment of an "excess parachute payment" within the meaning of
Section 280G of the Code or that would result, either individually or in the
aggregate, in payments that would be nondeductible pursuant to Section 162(m) of
the Code.

         6.6   Directors' and Officers' Indemnification and Insurance.

         (a) In the event of any threatened or actual claim, action, suit,
proceeding or investigation, whether civil, criminal or administrative,
including, without limitation, any such claim, action, suit, proceeding or
investigation in which any person who is now, or has been at any time prior to
the date of this Agreement, or who becomes prior to the Effective Time, a
director or officer or employee of Seller or any of its subsidiaries (the
"Indemnified Parties") is, or is threatened to be, made a party based in whole
or in part on, or arising in whole or in part out of, or pertaining to (i) the
fact that he is or was a director, officer or employee of the Seller, any of the
Seller's subsidiaries or any of their respective predecessors or (ii) this
Agreement, the Seller Option Agreement or any of the transactions contemplated
hereby or thereby, whether in any case asserted or arising before or after the
Effective Time, the parties hereto agree to cooperate and use their best efforts
to defend against and respond thereto. It is understood and agreed that after
the Effective Time, the Buyer shall indemnify and hold harmless, as and to the
fullest extent permitted by law, each such Indemnified Party against any losses,
claims, damages, liabilities, costs, expenses (including reasonable attorney's
fees and expenses in advance of the final disposition of any claim, suit,
proceeding or investigation to each Indemnified Party to the fullest extent
permitted by law upon receipt of any undertaking required by applicable law),
judgments, fines and amounts paid in settlement in connection with any such
threatened or actual claim, action, suit, proceeding or investigation, and in
the event of any such threatened or actual claim, action, suit, proceeding or
investigation (whether asserted of arising before or after the Effective Time),
the Indemnified Parties may retain counsel reasonably satisfactory to them after
consultation with the Buyer; provided, however, that (1) the Buyer shall have
the right to assume the defense thereof and upon such assumption the Buyer or
the Buyer Bank shall not be liable

                                       40

<PAGE>

to any Indemnified Party for any legal expenses of other counsel or any other
expenses subsequently incurred by any Indemnified Party in connection with the
defense thereof, except that if the Buyer elects not to assume such defense or
counsel for the Indemnified Parties reasonably advises the Indemnified Parties
that there are issues which raise conflicts of interest between the Buyer and
the Indemnified Parties, the Indemnified Parties may retain counsel reasonably
satisfactory to them after consultation with the Buyer, and the Buyer shall pay
the reasonable fees and expenses of such counsel for the Indemnified Parties,
(2) the Buyer shall be obligated pursuant to this paragraph to pay for only one
firm of counsel for all Indemnified Parties, (3) the Buyer shall not be liable
for any settlement effected without its prior written consent (which consent
shall not be unreasonably withheld) and (4) the Buyer shall have no obligation
hereunder to any Indemnified Party when and if a court of competent jurisdiction
shall ultimately determine, and such determination shall have become final and
nonappealable, that indemnification of such Indemnified Party in the manner
contemplated hereby is prohibited by applicable law. Any Indemnified Party
wishing to claim Indemnification under this Section 6.6, upon learning of any
such claim, action, suit, proceeding or investigation, shall notify the Buyer
thereof, provided that the failure to so notify shall not affect the obligations
of the Buyer under this Section 6.6 except to the extent such failure to notify
materially prejudices the Buyer. The Buyer's obligations under this Section 6.6
shall continue in full force and effect for a period of six (6) years from the
Effective Time; provided, however, that all rights to indemnification in respect
of any claim (a "Claim") asserted or made within such period shall continue
until the final disposition of such Claim.

         (b) The Buyer shall maintain the Seller's (including its subsidiaries')
existing directors' and officers' liability insurance (the "D&O Insurance")
covering persons who are currently covered by the Seller's D&O Insurance for a
period of six (6) years after the Effective Time on terms no less favorable than
those in effect on the date hereof and shall at the Effective Time provide
evidence of such extension of coverage to the Seller; provided, however, that
the Buyer may substitute therefor policies providing substantially comparable
coverage and containing terms and conditions no less favorable than those in
effect on the date hereof. In connection with the foregoing, the Seller agrees
to provide such insurer or substitute insurer with such representations as such
insurer may request with respect to the reporting of any prior claims.

         (c) In the event the Buyer or any of its successors or assigns (i)
consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger,
or (ii) transfers or conveys all or substantially all of its properties and
assets to any person, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of the Buyer
assume the obligations set forth in this section.

         (d) The provisions of this Section 6.6 are intended to be for the
benefit of, and enforceable by, each Indemnified Party and his or her heirs and
representatives, and nothing herein shall affect any indemnification rights that
any Indemnified Party and his or her heirs

                                       41

<PAGE>

and representatives may have under the charter or by-laws of the Seller or any
of its subsidiaries, any contract or applicable law.

         6.7 Additional Agreements. In case at any time after the Effective Time
any further action is necessary or desirable to carry out the purposes of this
Agreement or to vest the Surviving Corporation or the Surviving Bank with full
title to all properties, assets, rights, approvals, immunities and franchises of
any of the parties to the Merger or the Bank Merger, the proper officers and
directors of each party to this Agreement and their respective subsidiaries
shall take all such necessary action as may be reasonably requested by, and at
the sole expense of, the Buyer.

         6.8 Advice of Changes. The Buyer and the Seller shall each promptly
advise the other party of any change or event having a Material Adverse Effect
on it or which it believes would or would be reasonably likely to cause or
constitute a material breach of any of its representations, warranties or
covenants contained herein; provided, however, that the delivery of any notice
pursuant to this Section shall not limit or otherwise affect the remedies
available hereunder to the party receiving such notice.

         6.9 Update of Disclosure Schedules. From time to time prior to the
Effective Time, the Seller will promptly supplement or amend the Seller
Disclosure Schedule to reflect any matter which, if existing, occurring or known
at the date of this Agreement, would have been required to be set forth or
described in the Seller Disclosure Schedule or which is necessary to correct any
information in the Seller Disclosure Schedule which has been rendered inaccurate
thereby. No supplement or amendment to the Seller Disclosure Schedule shall have
any effect for the purpose of determining satisfaction of the conditions set
forth in Section 7.2(b) hereof or compliance by the Seller with the covenants
set forth in Article V hereof.

         6.10     Current Information.

         (a) As soon as practicable, the Seller will furnish to the Buyer copies
of all such financial statements and reports as it or any of its subsidiaries
shall send to its stockholders, the SEC or any other Governmental Authority, to
the extent any such reports furnished to any such Governmental Authority are not
confidential and except as legally prohibited thereby, and will furnish to the
Buyer such additional financial data as the Buyer may reasonably request.

         (b) Promptly upon receipt thereof, the Seller will furnish to the Buyer
copies of all internal control reports submitted to the Seller and its
subsidiaries by independent auditors in connection with each annual, interim or
special audit of the books of the Seller and its subsidiaries made by such
auditors.

         (c) The Seller will promptly notify the Buyer of any material change in
the normal course of business or in the operation of the properties of the
Seller or any of its subsidiaries and of any governmental complaints,
investigations or hearings (or

                                       42

<PAGE>

communications indicating that the same may be contemplated), or the institution
or the threat of material litigation involving the Seller or any of its
subsidiaries, and will keep the Buyer reasonably informed of such events.

         6.11 Liaison Committee. During the period from the date of this
Agreement to the Effective Time, the Seller will make available one or more of
its designated representatives (a) to confer on a regular and frequent basis
(not less than monthly) with representatives of the Buyer to report on (i) the
general status of the ongoing operations of the Seller and its subsidiaries,
(ii) the status of, and the action proposed to be taken with respect to, those
loans held by the Seller or any of its subsidiaries which, either individually
or in combination with one or more other loans to the same borrower thereunder,
have an aggregate outstanding principal amount of $5,000,000 or more and are
classified or non-performing assets, and (iii) the status of, and the action
proposed to be taken with respect to, foreclosed property and other real estate
owned, and (b) to communicate with respect to the manner in which the business
of the Seller and its subsidiaries are conducted and the disposition of certain
assets after the Effective Time, Year 2000 preparedness, the type and mix of
products and services, personnel matters, branch alignment, branch closings, the
granting of credit, and problem loan management, reserve adequacy and
accounting. In order to facilitate the foregoing, the Seller and the Buyer shall
promptly establish a liaison committee (the "Liaison Committee"), which will be
chaired by an officer designated by the Buyer and which will meet on a regular
basis to discuss these matters and may establish sub-committees from
time-to-time to pursue various issues. In addition, during the period from the
date of this Agreement to the Effective Time, on the date that the Seller Bank
delivers to the members of its senior credit committee applicable information
and reports for the next upcoming meeting of such committee, the Seller shall
provide to a designated representative of the Buyer located in Boston,
Massachusetts access to the same information and reports as are provided to the
Seller Bank's senior credit committee members with respect to new loans and
extensions of credit proposed to be made by the Seller Bank in excess of
$5,000,000. The representative designated by the Buyer shall also be allowed to
attend the Seller Bank's senior credit committee meetings and be a non-voting
observer thereof. The Seller, if requested by the Buyer, will assist the Buyer
to prepare to sell a portion of its single family residential mortgage loans and
mortgage loan servicing rights following the Effective Time; provided, that
Buyer shall indemnify the Seller and its subsidiaries for any fees, expenses and
charges incurred by Seller in connection therewith if the Merger is not
consummated in accordance with the terms of this Agreement.

         6.12 Bank Merger. Unless otherwise determined by the Buyer prior to the
Closing, at the effective time of the Bank Merger the Articles of Organization
and By-Laws of the Buyer Bank, as in effect immediately prior thereto, shall be
the Articles of Organization and By-Laws of the Surviving Bank until thereafter
amended as provided by law and such Articles of Organization and By-Laws. The
directors and officers of the Buyer Bank immediately prior to the effective time
of the Bank Merger shall be the directors and officers of the Surviving Bank,
each to hold office in accordance with the Articles of Organization and By-Laws
of the Surviving Bank and until their respective successors are duly elected or

                                       43

<PAGE>

appointed and qualified.

         6.13   Organization of the Merger Sub

         (a) Prior to the Effective Time, the Buyer will take any and all
necessary action to cause (i) the Merger Sub to be organized, (ii) the Merger
Sub to become a direct wholly owned subsidiary of the Buyer, (iii) the directors
and stockholders of the Merger Sub to approve the transactions contemplated by
this Agreement, (iv) the Merger Sub to execute one or more counterparts to this
Agreement and to deliver at least one such counterpart so executed to the
Seller, whereupon the Merger Sub shall become a party to and be bound by this
Agreement, and (v) the Merger Sub to take all necessary action to complete the
transactions contemplated hereby subject to the terms and conditions hereof.

         (b) On and as of the date the Merger Sub becomes a party to this

         existing and in good standing under the laws of The Commonwealth of
         Massachusetts and all of its outstanding capital stock are owned,
         directly, by the Buyer. Since the date of its organization, the Merger
         Sub has not engaged in any activities other than in connection with or
         as contemplated by this Agreement;

                  (ii) The Merger Sub has all necessary corporate power and
         authority to enter into this Agreement and to carry on its obligations
         hereunder. The execution and delivery of this Agreement by the Merger
         Sub and the consummation of the transactions contemplated hereby have
         been duly authorized by all necessary corporate action on the part of
         the Merger Sub and will not (A) conflict with or violate the Articles
         of Organization or By-laws of the Merger Sub or (B) conflict with or
         violate any law, rule, regulation, order, judgment or decree applicable
         to the Merger Sub or by which any of its properties or assets is bound
         or affected; and

                  (iii) The Merger Sub has executed and delivered this Agreement
         and this Agreement constitutes the legal, valid and binding obligation
         of the Merger Sub enforceable against the Merger Sub in accordance with
         its terms.

         6.14 Community Commitments. From and after the Effective Time, Buyer
shall use its reasonable efforts to continue the community commitments
undertaken by the Buyer Bank and the Seller Bank prior to the date hereof in the
communities currently served by each of the Buyer Bank and the Seller Bank.

         6.15 Consolidation of Corporate Structure. The parties hereto hereby
agree that prior to the consummation of the transactions contemplated hereby, at
the Buyer's request, the Seller shall, subject to the receipt of all required
regulatory approvals and consents with respect to such actions, take the

Bancorp, Inc. in an amount equal to the lesser of (i) the maximum amount that
Seller Bank may pay as a dividend to its shareholders without being required to
include in its gross income amounts charged against the reserves identified in
Section 593(e)(1)(B) or (C) of the Code, and (ii) an amount designated in
writing by the Buyer.

         (d) Subsequent to the declaration and payment of the Special Dividend
and not less than three (3) days prior to the Closing Date, the Seller shall
cause Affiliated Community Bancorp, Inc. to liquidate into the Seller.

         (e) In the event that the Merger is not consummated in accordance with

                              CONDITIONS PRECEDENT

         8.1 Termination. This Agreement may be terminated at any time prior to
the Effective Time, whether before or after approval of this Agreement and the
transactions contemplated hereby by the stockholders of the Seller:

         (a) by mutual consent of the Seller and the Buyer in a written
instrument, if the Board of Directors of each so determines by a vote of a
majority of the members of its entire Board;

         (b) by either the Board of Directors of the Buyer or the Board of
Directors of the Seller if any Governmental Authority that must grant a
Requisite Regulatory Approval has denied approval of the Merger and such denial
has become final and nonappealable or any Governmental Authority of competent
jurisdiction shall have issued a final nonappealable order permanently enjoining
or otherwise prohibiting the consummation of the transactions contemplated by
this Agreement;

         (c) by either the Board of Directors of the Buyer or the Board of
Directors of the Seller if the Merger shall not have been consummated on or
before March 31, 2000, unless the failure of the Closing to occur by such date
shall be due to the failure of the party seeking to terminate this Agreement to
perform or observe the covenants and agreements of such party set forth herein;

         (d) by either the Board of Directors of the Buyer or the Board of
Directors of the Seller (provided that the terminating party is not then in
material breach of any representation, warranty, covenant or other agreement
contained herein or in the Seller Option Agreement), in the event of a material
breach by the other party of any representation, warranty, covenant or other
agreement contained herein or in the Seller Option Agreement which breach is not
cured after thirty (30) days written notice thereof is given to the party
committing such breach;

                                       47

<PAGE>

         (e) by either the Buyer or the Seller if the approval of the Seller's
stockholders required for the consummation of the Merger shall not have been
obtained by reason of the failure to obtain the required vote at a duly held
meeting of such party's stockholders or at any adjournment thereof;

         (f) by the Buyer, if the Board of Directors of the Seller shall not
have publicly recommended to the stockholders of the Seller that such
stockholders vote in favor of the approval of this Agreement, the Merger and the
other transactions contemplated hereby or shall have withdrawn, modified or
amended such recommendation in a manner materially adverse to the Buyer; or

         (g) by the Buyer, if the Seller determines to negotiate with, or
disclose any nonpublic information relating to the Seller or any of its
subsidiaries or afford access to their properties, books or records to, any
Person in connection with an Acquisition Transaction.

         8.2      Effect of Termination.

         (a) In the event of termination of this Agreement by either the Buyer
or the Seller as provided in Section 8.1, this Agreement shall forthwith become
void and have no effect, and none of the Buyer, the Seller, any of their
respective subsidiaries or any of the officers or directors of any of them shall
have any liability of any nature whatsoever hereunder, or in connection with the
transactions contemplated hereby, except that (i) Sections 6.3(b), 8.2, 9.2 and
9.3 and all obligations of the Buyer to indemnify or reimburse the Seller under
Article V and Section 6.15 hereof and all other obligations of the parties
intended to be performed after the termination of this Agreement shall survive
any termination of this Agreement; provided, however, that, notwithstanding
anything to the contrary herein, all obligations of the Buyer to indemnify or
reimburse the Seller under Article V and Section 6.15 hereof shall terminate in
the event that this Agreement is terminated by the Buyer pursuant to Sections
8.1(f) or (g) hereof; provided, further however, that the preceding proviso
shall not apply upon a termination of this Agreement by the Buyer pursuant to
Section 8.1(g) hereof in the event that the Buyer has, as of such date of
termination, bid or made an offer to purchase any assets or liabilities to be
sold in connection with the Branch Divestiture unless the Buyer shall have
revoked or withdrawn such bid or offer, and (ii) notwithstanding anything to the
contrary contained in this Agreement, neither the Buyer nor the Seller shall be
relieved or released from any liabilities or damages arising out of its willful
breach of any provision of this Agreement.

         (b) If this Agreement is terminated as a result of any breach of a
representation, warranty, covenant or other agreement which is caused by the
willful breach of a party hereto, such party shall be liable to the other party
for all out-of-pocket costs and expenses, including, without limitation, the
reasonable fees and expenses of lawyers, accountants and investment bankers,
incurred by such other party in connection with the entering into of this
Agreement and the carrying out of any and all acts contemplated hereunder
("Expenses"). The payment of Expenses is not an exclusive remedy, but is in
addition to any other rights or remedies available to the parties hereto at law
or in equity.

         8.3 Amendment. Subject to compliance with applicable law, this
Agreement may be amended by the parties hereto, by action taken or authorized by
their respective Boards of Directors, at any time before or after approval of
the matters presented in connection with Merger by the stockholders of the Buyer
and the Seller; provided, however, that after any approval of the transactions
contemplated by this Agreement by the stockholders of the Seller, there may not
be, without further approval of such stockholders, any amendment of this
Agreement that changes the amount or the form of the consideration to be
delivered hereunder to the holders of Seller Common Stock, other than as
contemplated by this Agreement. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto.

         8.4 Extension; Waiver. At any time prior to the Effective Time, the
parties hereto, by action taken or authorized by their respective Board of
Directors, may, to the extent legally allowed, (a) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(b) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto and (c) waive compliance
with any of the agreements or conditions contained herein; provided, however,
that after any approval of the transactions contemplated by this Agreement by
the stockholders of the Seller, there may not be, without further approval of
such stockholders, any extension or waiver of this Agreement or any portion
thereof which reduces the amount or changes the form of the consideration to be
delivered to the holders of Seller Common Stock hereunder, other than as
contemplated by this Agreement. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party, but such extension or waiver or
failure to insist on strict compliance with an obligation, covenant, agreement
or condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent or other failure.


                                   ARTICLE IX

                                  MISCELLANEOUS

the latest to occur of the conditions set forth in Article VII hereof, unless
extended by mutual agreement of the parties (the "Closing Date"); provided,
however, that in no event shall the Closing take place prior to January 3, 2000,
which at the Buyer's discretion may be extended to a date no later than January
31, 2000.

         9.2 Nonsurvival of Representations, Warranties and Agreements. None of
the representations, warranties, covenants and agreements in this Agreement or
in any instrument delivered pursuant to this Agreement (other than the Seller
Option Agreement, which shall

                                       49

in part after the Effective Time.

only and shall not affect in any way the meaning or interpretation of this
Agreement. Whenever the words "include," "includes" or "including" are used in

Agreement

                                       51

<PAGE>

shall for any reason be held invalid, illegal or unenforceable in any respect,
by any court of competent jurisdiction, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Agreement and the
parties shall use their reasonable best efforts to substitute a valid, legal and
enforceable provision which, insofar as practicable, implements the original
purposes and intents of this Agreement.

         9.10 Publicity. Except as otherwise required by applicable law or the
rules of the NASD, neither the Buyer nor the Seller shall, or shall permit any

statement concerning, the transactions contemplated by this Agreement without
the consent of the party, which consent shall not be unreasonably withheld.

         9.11 Assignment; Reliance of Other Parties. Neither this Agreement nor

parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other parties. Subject to the preceding sentence, this

the parties and their respective successors and assigns. Except as otherwise
specifically provided in Sections 6.5(b) and 6.6, and with respect to the

         9.12 Specific Performance. The parties hereto agree that irreparable
damage would occur in the event that the provisions contained in this Agreement

specifically the terms and provisions thereof in any court of the United States
or any state having jurisdiction, this being in addition to any other remedy to
which they are entitled at law or in equity.

contained in this Agreement, prior to the Effective Time, the Buyer shall be
entitled to revise the structure of the Merger, the Bank Merger and the other
transactions contemplated hereby and thereby, provided that, each of the

                             STOCK OPTION AGREEMENT

         STOCK OPTION AGREEMENT, dated June 21, 1999, between UST CORP., a
Massachusetts corporation ("Issuer"), and CITIZENS FINANCIAL GROUP, INC., a
Delaware corporation ("Grantee").

                                   WITNESSETH:

         WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of
Merger of even date herewith (the "Merger Agreement"), which agreement has been
executed by the parties hereto immediately prior to this Agreement; and

         WHEREAS, as a condition to Grantee's entering into the Merger Agreement
and in consideration therefor, Issuer has agreed to grant Grantee the Option (as
hereinafter defined):

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements set forth herein and in the Merger Agreement, the
parties hereto agree as follows:

         1. (a) Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "Option") to purchase, subject to the terms hereof, up to 8,541,333
fully paid and nonassessable shares of Issuer's Common Stock, par value $0.625
per share ("Common Stock"), at a price of $24.25 per share (the "Option Price");
provided further that in no event shall the number of shares of Common Stock for
which this Option is exercisable exceed 19.9% of the Issuer's issued and
outstanding shares of Common Stock without giving effect to any shares subject
to or issued pursuant to the Option. The number of shares of Common Stock that
may be received upon the exercise of the Option and the Option Price are subject
to adjustment as herein set forth.

            (b) In the event that any additional shares of Common Stock are
issued or otherwise become outstanding after the date of this Agreement (other
than pursuant to this Agreement), the number of shares of Common Stock subject
to the Option shall be increased so that, after such issuance, it equals 19.9%
of the number of shares of Common Stock then issued and outstanding without
giving effect to any shares subject or issued pursuant to the Option. Nothing
contained in this Section 1(b) or elsewhere in this Agreement shall be deemed to
authorize Issuer or Grantee to breach any provision of the Merger Agreement.

         2. (a) The Holder (as hereinafter defined) may exercise the Option, in
whole or part, and from time to time, if, but only if, both an Initial
Triggering Event (as hereinafter defined) and a Subsequent Triggering Event (as
hereinafter defined) shall have occurred prior to the occurrence of an Exercise
Termination Event (as hereinafter defined); provided that the Holder shall have
sent the written notice of such exercise (as provided in subsection (e) of this
Section 2) within 100 days following such Subsequent Triggering Event. Each of
the following shall be an "Exercise Termination Event": (i) the Effective Time
(as defined in the Merger Agreement) of the Merger; (ii) termination of the
Merger Agreement in accordance

                                        1

<PAGE>

with the provisions thereof if such termination occurs prior to the occurrence
of an Initial Triggering Event except a termination by Grantee pursuant to
Section 8.1(d) of the Merger Agreement (unless the breach by Issuer giving rise
to such right of termination is non- volitional); or (iii) the passage of
eighteen months after termination of the Merger Agreement if such termination
follows the occurrence of an Initial Triggering Event or is a termination by
Grantee pursuant to Section 8.1(d) of the Merger Agreement (unless the breach by
Issuer giving rise to such right of termination is non-volitional)(provided that
if an Initial Triggering Event continues or occurs beyond such termination and
prior to the passage of such eighteen-month period, the Exercise Termination
Event shall be twelve months from the expiration of the Last Triggering Event
but in no event more than eighteen months after such termination). The "Last
Triggering Event" shall mean the last Initial Triggering Event to expire. The
term "Holder" shall mean the holder or holders of the Option.

            (b) The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                           (i) Issuer or any of its Subsidiaries (each an
"Issuer Subsidiary"), without having received Grantee's prior written consent,
shall have entered into an agreement to engage in an Acquisition Transaction (as
hereinafter defined) with any person (the term "person" for purposes of this
Agreement having the meaning assigned thereto in Sections 3(a)(9) and 13(d)(3)
of the Securities Exchange Act of 1934, as amended (the "1934 Act"), and the
rules and regulations thereunder) other than Grantee or any of its Subsidiaries
(each a "Grantee Subsidiary") or the Board of Directors of Issuer shall have
recommended that the stockholders of Issuer approve or accept any Acquisition
Transaction or shall have failed to publicly oppose an Acquisition Transaction,
in each case with any person other than Grantee or a Grantee Subsidiary. For
purposes of this Agreement, "Acquisition Transaction" shall mean (w) a merger or
consolidation, or any similar transaction, involving Issuer or any Significant
Subsidiary (as defined in Rule 1-02 of Regulation S-X promulgated by the
Securities and Exchange Commission (the "SEC") of Issuer, (x) a purchase, lease
or other acquisition of all or a substantial portion of the assets of Issuer or
any Significant Subsidiary of Issuer, (y) a purchase or other acquisition
(including by way of merger, consolidation, share exchange or otherwise) of
securities representing 10% or more of the voting power of Issuer or any
Significant Subsidiary of Issuer, or (z) any substantially similar transaction;
provided, however, that in no event shall any merger, consolidation, purchase,
liquidation, dividend in kind, reorganization or similar transaction involving
only the Issuer and one or more of its Subsidiaries or involving only any two or
more of such Subsidiaries, be deemed to be an Acquisition Transaction, provided
any such transaction is not entered into in violation of the terms of the Merger
Agreement;

                           (ii) Issuer or any Issuer Subsidiary, without having
received Grantee's prior written consent, shall have authorized, recommended,
proposed or publicly announced its intention to authorize, recommend or propose,
to engage in an Acquisition Transaction with any person other than Grantee or a
Grantee Subsidiary, or the Board of

                                        2

<PAGE>

Directors of Issuer shall have publicly withdrawn or modified, or publicly
announced its intention to withdraw or modify, in any manner adverse to Grantee,
its recommendation that the stockholders of Issuer approve the transactions
contemplated by the Merger Agreement;

                           (iii) The shareholders of Issuer shall have voted and
failed to approve and adopt the Merger Agreement and the Merger at a meeting
which has been held for that purpose or any adjournment or postponement thereof,
or such meeting shall not have been held in violation of the Merger Agreement or
shall have been canceled prior to termination of the Merger Agreement if, prior
to such meeting (or if such meeting shall not have been held or shall have been
canceled, prior to such termination), any person (other than the Grantee or a
Grantee Subsidiary) shall have made a proposal to Issuer or its stockholders by
public announcement or written communication that is or becomes the subject of
public disclosure to engage in an Acquisition Transaction;

                           (iv) Any person other than Grantee, any Grantee
Subsidiary or any Issuer Subsidiary acting in a fiduciary capacity in the
ordinary course of its business shall have acquired beneficial ownership or the
right to acquire beneficial ownership of 10% or more of the outstanding shares
of Common Stock (the term "beneficial ownership" for purposes of this Option
Agreement having the meaning assigned thereto in Section 13(d) of the 1934 Act,
and the rules and regulations thereunder);

                           (v) Any person other than Grantee or any Grantee
Subsidiary shall have made a bona fide proposal to Issuer or its stockholders by
public announcement or written communication that is or becomes the subject of
public disclosure to engage in an Acquisition Transaction;

                           (vi) After an overture is made by a third party to
Issuer or its stockholders to engage in an Acquisition Transaction, Issuer shall
have breached any covenant or obligation contained in the Merger Agreement and
such breach (x) would entitle Grantee to terminate the Merger Agreement and (y)
shall not have been cured prior to the Notice Date (as defined below); or

                           (vii) Any person other than Grantee or any Grantee
Subsidiary, other than in connection with a transaction to which Grantee has
given its prior written consent, shall have filed an application or notice with
the Federal Reserve Board, or other federal or state bank regulatory authority,
whether in draft or final form, for approval to engage in an Acquisition
Transaction.

            (c) The term "Subsequent Triggering Event" shall mean either of the
following events or transactions occurring after the date hereof:

                           (i) The acquisition by any person of beneficial
ownership of 20% or more of the then outstanding Common Stock; or

                                        3

<PAGE>

                           (ii) The occurrence of the Initial Triggering Event
described in clause (i) of subsection (b) of this Section 2, except that the
percentage referred to in clause (y) shall be 20%.

            (d) Issuer shall notify Grantee promptly in writing of the
occurrence of any Initial Triggering Event or Subsequent Triggering Event
(together, a "Triggering Event"), it being understood that the giving of such
notice by Issuer shall not be a condition to the right of the Holder to exercise
the Option.

            (e) In the event the Holder is entitled to and wishes to exercise
the Option, it shall send to Issuer a written notice (the date of which being
herein referred to as the "Notice Date") specifying (i) the total number of
shares it will purchase pursuant to such exercise and (ii) a place and date not
earlier than three business days nor later than 60 business days from the Notice
Date for the closing of such purchase (the "Closing Date"); provided that if
prior notification to or approval of the Federal Reserve Board or any other
regulatory agency is required in connection with such purchase, the Holder shall
promptly file the required notice or application for approval and shall
expeditiously process the same and the period of time that otherwise would run
pursuant to this sentence shall run instead from the date on which any required
notification periods (including any extensions thereof) have expired or been
terminated or such approvals have been obtained and any requisite waiting period
or periods (including any extensions thereof) shall have passed. Any exercise of
the Option shall be deemed to occur on the Notice Date relating thereto.

            (f) At the closing referred to in subsection (e) of this Section 2,
the Holder shall pay to Issuer the aggregate purchase price for the shares of
Common Stock purchased pursuant to the exercise of the Option in immediately
available funds by wire transfer to a bank account designated by Issuer,
provided that failure or refusal of Issuer to designate such a bank account
shall not preclude the Holder from exercising the Option.

            (g) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock purchased by the Holder and, if the Option should be
exercised in part only, a new Option evidencing the rights of the Holder thereof
to purchase the balance of the shares purchasable hereunder, and the Holder
shall deliver to Issuer a copy of this Agreement and a letter agreeing that the
Holder will not offer to sell or otherwise dispose of such shares in violation
of applicable law or the provisions of this Agreement.

            (h) Certificates for Common Stock delivered at a closing hereunder
may be endorsed with a restrictive legend that shall read substantially as
follows:

         "The transfer of the shares represented by this certificate is subject
         to certain provisions of an agreement between the registered holder
         hereof and Issuer and

                                        4

<PAGE>

         to resale restrictions arising under the Securities Act of 1933, as
         amended. A copy of such agreement is on file at the principal office of
         Issuer and will be provided to the holder hereof without charge upon
         receipt by Issuer of a written request therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference; and (iii) the legend shall be removed
in its entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

                  (i) Upon the giving by the Holder to Issuer of the written
notice of exercise of the Option provided for under subsection (e) of this
Section 2 and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered to
the Holder. Issuer shall pay all expenses, and any and all United States
federal, state and local taxes and other charges that may be payable in
connection with the preparation, issue and delivery of stock certificates under
this Section 2 in the name of the Holder or its assignee, transferee or
designee.

         3. Issuer agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,
merger, dissolution or sale of assets, or by any other voluntary act, avoid or
seek to avoid the observance or performance of any of the covenants,
stipulations or conditions to be observed or performed hereunder by Issuer;
(iii) promptly to take all action as may from time to time be required
(including (x) complying with all premerger notification, reporting and waiting
period requirements specified in 15 U.S.C. sec. 18a and regulations promulgated
thereunder and (y) in the event, under the Bank Holding Company Act of 1956, as
amended (the "BHCA"), or the Change in Bank Control Act of 1978, as amended, or
any state banking law, prior approval of or notice to the Federal Reserve Board
or to any other federal or state regulatory authority is necessary before the
Option may be exercised, cooperating fully with the Holder in preparing such
applications or notices and providing such information to the Federal Reserve

                                        5

<PAGE>

Board or such other federal or state regulatory authority as they may require)
in order to permit the Holder to exercise the Option and Issuer duly and
effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly
to take all action provided herein to protect the rights of the Holder against
dilution.

         4. This Agreement (and the Option granted hereby) are exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock purchasable hereunder.
The terms "Agreement" and "Option" as used herein include any Stock Option
Agreements and related Options for which this Agreement (and the Option granted
hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

         5. In addition to the adjustment in the number of shares of Common
Stock that are purchasable upon exercise of the Option pursuant to Section 1 of
this Agreement, the number of shares of Common Stock purchasable upon the
exercise of the Option and the Option Price shall be subject to adjustment from
time to time as provided in this Section 5. In the event of any change in, or
distributions in respect of, the Common Stock by reason of stock dividends,
split-ups, mergers, recapitalizations, combinations, subdivisions, conversions,
exchanges of shares, distributions on or in respect of the Common Stock that
would be prohibited under the terms of the Merger Agreement, or the like, the
type and number of shares of Common Stock purchasable upon exercise hereof and
the Option Price shall be appropriately adjusted in such manner as shall fully
preserve the economic benefits provided hereunder and proper provision shall be
made in any agreement governing any such transaction to provide for such proper
adjustment and the full satisfaction of the Issuer's obligations hereunder.

         6. Upon the occurrence of a Subsequent Triggering Event that occurs
prior to an Exercise Termination Event, Issuer shall, at the request of Grantee
delivered within 100 day after such Subsequent Triggering Event (whether on its
own behalf or on behalf of any subsequent holder of this Option (or part
thereof) or any of the shares of Common Stock issued pursuant hereto), promptly
prepare, file and keep current a shelf registration statement under the 1933 Act
covering the resale of this Option and any shares issued pursuant to this Option
and the issuance of any shares issuable pursuant to this Option to the extent
then permitted under the rules, regulations or policies of the SEC and, to the
extent not so permitted, the resale of such shares issuable pursuant to this
Option. The Issuer shall use its

                                        6

<PAGE>

reasonable best efforts to cause such registration statement to become effective
and remain current in order to permit the sale or other disposition of this
Option and any shares of Common Stock issued upon total or partial exercise of
this Option ("Option Shares") in accordance with any plan of disposition
requested by Grantee. Issuer will use its reasonable best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 180 days from the day such registration
statement first becomes effective or such shorter time as may be reasonably
necessary to effect such sales or other dispositions. Grantee shall have the
right to demand two such registrations. The foregoing notwithstanding, if, at
the time of any request by Grantee for registration of the Option or Option
Shares as provided above, Issuer is in registration with respect to an
underwritten public offering of shares of Common Stock, and if in the good faith
judgment of the managing underwriter or managing underwriters, or, if none, the
sole underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
and provided, however, that after any such required reduction the number of
Option Shares to be included in such offering for the account of the Holder
shall constitute at least 25% of the total number of shares to be sold by the
Holder and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance as promptly as practical and no reduction shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any underwriting agreement relating to the sale of such shares, but
only to the extent of obligating itself in respect of representations,
warranties, indemnities and other agreements customarily included in such
underwriting agreements for the Issuer. Upon receiving any request under this
Section 6 from any Holder, Issuer agrees to send a copy thereof to any other
person known to Issuer to be entitled to registration rights under this Section
6, in each case by promptly mailing the same, postage prepaid, to the address of
record of the persons entitled to receive such copies. Notwithstanding anything
to the contrary contained herein, in no event shall Issuer be obligated to
effect more than two registrations pursuant to this Section 6 by reason of the
fact that there shall be more than one Grantee as a result of any assignment or
division of this Agreement.

         7. (a) Immediately prior to the occurrence of a Repurchase Event (as
defined below), (i) following a request of the Holder, delivered prior to an
Exercise Termination Event, Issuer (or any successor thereto) shall repurchase
the Option from the Holder at a price (the "Option Repurchase Price") equal to
the amount by which (A) the market/offer price (as defined below) exceeds (B)
the Option Price, multiplied by the number of shares for which this Option may
then be exercised and (ii) at the request of the owner of Option Shares from
time to time (the "Owner") delivered within 100 days after such occurrence (or
such later period as provided in Section 10), Issuer shall repurchase such
number of the Option Shares from the Owner as the Owner shall designate at a
price (the "Option Share Repurchase Price")

                                        7

<PAGE>

equal to the market/offer price multiplied by the number of Option Shares so
designated. The term "market/offer price" shall mean the highest of (i) the
price per share of Common Stock at which a tender offer or exchange offer
therefor has been made, (ii) the price per share of Common Stock to be paid by
any third party pursuant to an agreement with Issuer, (iii) the highest closing
price for shares of Common Stock within the six-month period immediately
preceding the date the Holder gives notice of the required repurchase of this
Option or the Owner gives notice of the required repurchase of Option Shares, as
the case may be, or (iv) in the event of a sale of all or a substantial portion
of Issuer's assets, the sum of the price paid in such sale for such assets and
the current market value of the remaining assets of Issuer as determined by a
nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, divided by the number of shares of Common Stock of
Issuer outstanding at the time of such sale. In determining the market/offer
price, the value of consideration other than cash shall be determined by a
nationally recognized investment banking firm selected by the Holder or Owner,
as the case may be, and reasonably acceptable to the Issuer.

                  (b) The Holder and the Owner, as the case may be, may exercise
its right to require Issuer to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to Issuer, at its
principal office, a copy of this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7. Within the later to occur of (x) five business days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto and (y) the time that is
immediately prior to the occurrence of a Repurchase Event, Issuer shall deliver
or cause to be delivered to the Holder the Option Repurchase Price and/or to the
Owner the Option Share Repurchase Price therefor or the portion thereof that
Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that Issuer is prohibited under applicable
law or regulation from repurchasing the Option and/or the Option Shares in full,
Issuer shall immediately so notify the Holder and/or the Owner and thereafter
deliver or cause to be delivered, from time to time, to the Holder and/or the
Owner, as appropriate, the portion of the Option Repurchase Price and the Option
Share Repurchase Price, respectively, that it is no longer prohibited from
delivering, within five business days after the date on which Issuer is no
longer so prohibited; provided, however, that if Issuer at any time after
delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7
is prohibited under applicable law or regulation from delivering to the Holder
and/or the Owner, as appropriate, the Option Repurchase Price and the Option
Share Repurchase Price, respectively, in full (and Issuer hereby undertakes to
use its best efforts to obtain all required regulatory and legal approvals and
to file any required notices as promptly as practicable in order to accomplish
such repurchase), the Holder or Owner may revoke its notice of repurchase of the
Option or the Option Shares either in whole or to the extent of the prohibition,
whereupon, in the latter case, Issuer shall promptly (i)

                                        8

<PAGE>

deliver to the Holder and/or the Owner, as appropriate, that portion of the
Option Repurchase Price or the Option Share Repurchase Price that Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the
Holder, a new Stock Option Agreement evidencing the right of the Holder to
purchase that number of shares of Common Stock obtained by multiplying the
number of shares of Common Stock for which the surrendered Stock Option
Agreement was exercisable at the time of delivery of the notice of repurchase by
a fraction, the numerator of which is the Option Repurchase Price less the
portion thereof theretofore delivered to the Holder and the denominator of which
is the Option Repurchase Price, or (B) to the Owner a certificate for the Option
Shares it is then so prohibited from repurchasing.

                  (d) For purposes of this Section 7, a Repurchase Event shall
be deemed to have occurred (i) upon the consummation of any merger,
consolidation or similar transaction involving Issuer or any purchase, lease or
other acquisition of all or a substantial portion of the assets of Issuer, other
than any such transaction which would not constitute an Acquisition Transaction
pursuant to the proviso to Section 2 (b) (i) hereof or (ii) upon the acquisition
by any person of beneficial ownership of 50% or more of the then outstanding
shares of Common Stock, provided that no such event shall constitute a
Repurchase Event unless a Subsequent Triggering Event shall have occurred prior
to an Exercise Termination Event. The parties hereto agree that Issuer's
obligations to repurchase the Option or Option Shares under this Section 7 shall
not terminate upon the occurrence of an Exercise Termination Event unless no
Subsequent Triggering Event shall have occurred prior to the occurrence of an
Exercise Termination Event.

         8. (a) In the event that prior to an Exercise Termination Event, Issuer
shall enter into an agreement (i) to consolidate with or merge into any person,
other than Grantee or one of its Subsidiaries, and shall not be the continuing
or surviving corporation of such consolidation or merger, (ii) to permit any
person, other than Grantee or one of its Subsidiaries, to merge into Issuer and
Issuer shall be the continuing or surviving corporation, but, in connection with
such merger, the then outstanding shares of Common Stock shall be changed into
or exchanged for stock or other securities of any other person or cash or any
other property or the then outstanding shares of Common Stock shall after such
merger represent less than 50% of the outstanding voting shares and voting share
equivalents of the merged company, or (iii) to sell or otherwise transfer all or
substantially all of its assets to any person, other than Grantee or one of its
Subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provision so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option (the "Substitute
Option"), at the election of the Holder, of either (x) the Acquiring Corporation
(as hereinafter defined) or (y) any person that controls the Acquiring
Corporation.

                  (b)      The following terms have the meanings indicated:

                           (1) "Acquiring Corporation" shall mean (i) the
continuing or

                                        9

<PAGE>

surviving corporation of a consolidation or merger with Issuer (if other than
Issuer), (ii) Issuer in a merger in which Issuer is the continuing or surviving
person, and (iii) the transferee of all or substantially all of Issuer's assets.

                           (2) "Substitute Common Stock" shall mean the common
stock issued by the issuer of the Substitute Option upon exercise of the
Substitute Option.

                           (3) "Assigned Value" shall mean the market/offer
price, as defined in Section 7.

                           (4) "Average Price" shall mean the average closing
price of a share of the Substitute Common Stock for the one year immediately
preceding the consolidation, merger or sale in question, but in no event higher
than the closing price of the shares of Substitute Common Stock on the day
preceding such consolidation, merger or sale; provided that if Issuer is the
issuer of the Substitute Option, the Average Price shall be computed with
respect to a share of common stock issued by the person merging into Issuer or
by any company which controls or is controlled by such person, as the Holder may
elect.

                  (c) The Substitute Option shall have the same terms as the
Option, provided, that if the terms of the Substitute Option cannot, for legal
reasons, be the same as the Option, such terms shall be as similar as possible
and in no event less advantageous to the Holder. The issuer of the Substitute
Option shall also enter into an agreement with the then Holder or Holders of the
Substitute Option in substantially the same form as this Agreement, which shall
be applicable to the Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of Substitute Common Stock as is equal to the Assigned Value
multiplied by the number of shares of Common Stock for which the Option is then
exercisable, divided by the Average Price. The exercise price of the Substitute
Option per share of Substitute Common Stock shall then be equal to the Option
Price multiplied by a fraction, the numerator of which shall be the number of
shares of Common Stock for which the Option is then exercisable and the
denominator of which shall be the number of shares of Substitute Common Stock
for which the Substitute Option is exercisable.

                  (e) In no event, pursuant to any of the foregoing paragraphs,
shall the Substitute Option be exercisable for more than 19.9% of the shares of
Substitute Common Stock outstanding prior to exercise of the Substitute Option.
In the event that the Substitute Option would be exercisable for more than 19.9%
of the shares of Substitute Common Stock outstanding prior to exercise but for
this clause (e), the issuer of the Substitute Option (the "Substitute Option
Issuer") shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in this
clause (e) over (ii) the value of the Substitute Option after giving effect to
the limitation in this clause (e). This difference in value shall be determined
by a nationally recognized investment banking firm

                                       10

<PAGE>

selected by the Holder or the Owner, as the case may be, and reasonably
acceptable to the Acquiring Corporation.

                  (f) Issuer shall not enter into any transaction described in
subsection (a) of this Section 8 unless the Acquiring Corporation and any person
that controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

         9.       (a) At the request of the holder of the Substitute Option (the
"Substitute Option Holder"), the issuer of the Substitute Option (the
"Substitute Option Issuer") shall repurchase the Substitute Option from the
Substitute Option Holder at a price (the "Substitute Option Repurchase Price")
equal to (x) the amount by which (i) the Highest Closing Price (as hereinafter
defined) exceeds (ii) the exercise price of the Substitute Option, multiplied by
the number of shares of Substitute Common Stock for which the Substitute Option
may then be exercised plus (y) Grantee's Out-of-Pocket Expenses (to the extent
not previously reimbursed), and at the request of the owner (the "Substitute
Share Owner") of shares of Substitute Common Stock (the "Substitute Shares"),
the Substitute Option Issuer shall repurchase the Substitute Shares at a price
(the "Substitute Share Repurchase Price") equal to (x) the Highest Closing Price
multiplied by the number of Substitute Shares so designated plus (y) Grantee's
Out-of-Pocket Expenses (to the extent not previously reimbursed). The term
"Highest Closing Price" shall mean the highest closing price for shares of
Substitute Common Stock within the six-month period immediately preceding the
date the Substitute Option Holder gives notice of the required repurchase of the
Substitute Option or the Substitute Share Owner gives notice of the required
repurchase of the Substitute Shares, as applicable.

                  (b) The Substitute Option Holder and the Substitute Share
Owner, as the case may be, may exercise its respective right to require the
Substitute Option Issuer to repurchase the Substitute Option and the Substitute
Shares pursuant to this Section 9 by surrendering for such purpose to the
Substitute Option Issuer, at its principal office, the agreement for such
Substitute Option (or, in the absence of such an agreement, a copy of this
Agreement) and certificates for Substitute Shares accompanied by a written
notice or notices stating that the Substitute Option Holder or the Substitute
Share Owner, as the case may be, elects to require the Substitute Option Issuer
to repurchase the Substitute Option and/or the Substitute Shares in accordance
with the provisions of this Section 9. As promptly as practicable, and in any
event within five business days after the surrender of the Substitute Option
and/or certificates representing Substitute Shares and the receipt of such
notice or notices relating thereto, the Substitute Option Issuer shall deliver
or cause to be delivered to the Substitute Option Holder the Substitute Option
Repurchase Price and/or to the Substitute Share Owner the Substitute Share
Repurchase Price therefor or the portion thereof which the Substitute Option
Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that the Substitute Option Issuer is
prohibited under applicable law or regulation from repurchasing the Substitute
Option and/or the Substitute

                                       11

<PAGE>

Shares in part or in full, the Substitute Option Issuer shall immediately so
notify the Substitute Option Holder and/or the Substitute Share Owner and
thereafter deliver or cause to be delivered, from time to time, to the
Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the
portion of the Substitute Share Repurchase Price, respectively, which it is no
longer prohibited from delivering, within five business days after the date on
which the Substitute Option Issuer is no longer so prohibited; provided,
however, that if the Substitute Option Issuer is at any time after delivery of a
notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
under applicable law or regulation from delivering to the Substitute Option
Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option
Repurchase Price and the Substitute Share Repurchase Price, respectively, in
full (and the Substitute Option Issuer shall use its best efforts to receive all
required regulatory and legal approvals as promptly as practicable in order to
accomplish such repurchase), the Substitute Option Holder or Substitute Share
Owner may revoke its notice of repurchase of the Substitute Option or the
Substitute Shares either in whole or to the extent of the prohibition,
whereupon, in the latter case, the Substitute Option Issuer shall promptly (i)
deliver to the Substitute Option Holder or Substitute Share Owner, as
appropriate, that portion of the Substitute Option Repurchase Price or the
Substitute Share Repurchase Price that the Substitute Option Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the
Substitute Option Holder, a new Substitute Option evidencing the right of the
Substitute Option Holder to purchase that number of shares of the Substitute
Common Stock obtained by multiplying the number of shares of the Substitute
Common Stock for which the surrendered Substitute Option was exercisable at the
time of delivery of the notice of repurchase by a fraction, the numerator of
which is the Substitute Option Repurchase Price less the portion thereof
theretofore delivered to the Substitute Option Holder and the denominator of
which is the Substitute Option Repurchase Price, or (B) to the Substitute Share
Owner, a certificate for the Substitute Option Shares it is then so prohibited
from repurchasing.

         10. The 100-day period for exercise of certain rights under Sections 2,
6, 7 and 13 shall be extended: (i) to the extent necessary to obtain all
regulatory approvals for the exercise of such rights, and for the expiration of
all statutory waiting periods; and (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise.

         11. Issuer hereby represents and warrants to Grantee as follows:

                  (a) Issuer has full corporate power and authority to execute
and deliver this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of Issuer and no other corporate proceedings on the part of
Issuer are necessary to authorize this Agreement or to consummate the
transactions so contemplated. This Agreement has been duly and validly executed
and delivered by Issuer.

                                       12

<PAGE>

                  (b) Issuer has taken all necessary corporate action to
authorize and reserve and to permit it to issue, and at all times from the date
hereof through the termination of this Agreement in accordance with its terms
will have reserved for issuance upon the exercise of the Option, that number of
shares of Common Stock equal to the maximum number of shares of Common Stock at
any time and from time to time issuable hereunder, and all such shares, upon
issuance pursuant hereto, will be duly authorized, validly issued, fully paid,
nonassessable, and will be delivered free and clear of all claims, liens,
encumbrance and security interests and not subject to any preemptive rights.

                  (c) Issuer has taken all action (including if required
redeeming all of the Rights or amending or terminating the Rights Agreement) so
that the entering into of this Option Agreement, the acquisition of shares of
Common Stock hereunder and the other transactions contemplated hereby do not and
will not result in the grant of any rights to any person under the Rights
Agreement or enable or require the Rights to be exercised, distributed or
triggered.

         12. Grantee hereby represents and warrants to Issuer that:

                  (a) Grantee has all requisite corporate power and authority to
enter into this Agreement and, subject to any approvals or consents referred to
herein, to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of Grantee. This Agreement has been duly executed and delivered by Grantee.

                  (b) The Option is not being, and any shares of Common Stock or
other securities acquired by Grantee upon exercise of the Option will not be,
acquired with a view to the public distribution thereof and will not be
transferred or otherwise disposed of except in a transaction registered or
exempt from registration under the Securities Act.

         13. Neither of the parties hereto may assign any of its rights or
obligations under this Option Agreement or the Option created hereunder to any
other person, without the express written consent of the other party, except
that in the event a Subsequent Triggering Event shall have occurred prior to an
Exercise Termination Event, Grantee, subject to the express provisions hereof,
may assign in whole or in part its rights and obligations hereunder within 90
days following such Subsequent Triggering Event (or such later period as
provided in Section 10); provided, however, that until the date 15 days
following the date on which the Federal Reserve Board approves an application by
Grantee under the BHCA to acquire the shares of Common Stock subject to the
Option, Grantee may not assign its rights under the Option except in (i) a
widely dispersed public distribution, (ii) a private placement in which no one
party acquires the right to purchase in excess of 2% of the voting shares of
Issuer, (iii) an assignment to a single party (e.g., a broker or investment
banker) for the purpose of conducting a widely dispersed public distribution on
Grantee's behalf, or (iv) any other manner

                                       13

<PAGE>

approved by the Federal Reserve Board.

         14. Each of Grantee and Issuer will use its best efforts to make all
filings with, and to obtain consents of, all third parties and governmental
authorities necessary to the consummation of the transactions contemplated by
this Agreement, including without limitation making application to list the
shares of Common Stock issuable hereunder on the Nasdaq National Stock Market
upon official notice of issuance and applying to the Federal Reserve Board under
the BHCA for approval to acquire the shares issuable hereunder, but Grantee
shall not be obligated to apply to state banking authorities for approval to
acquire the shares of Common Stock issuable hereunder until such time, if ever,
as it deems appropriate to do so.

         15.      (a) Grantee may, at any time during which Issuer would be
required to repurchase the Option or any Option Shares pursuant to Section 7,
surrender the Option (together with any Option Shares issued to and then owned
by Grantee) to Issuer in exchange for a cash fee equal to the Surrender Price
(as defined below); provided, however, that Grantee may not exercise its rights
pursuant to this Section 15 if Issuer has repurchased the Option (or any portion
thereof) or any Option Shares pursuant to Section 7. The "Surrender Price" shall
be equal to (i) $56.3 million, plus (ii) if applicable, the aggregate purchase
price previously paid pursuant hereto by Grantee with respect to any Option
Shares, minus (iii) if applicable, the sum of (A) the excess of (1) the net cash
amounts, if any, received by Grantee pursuant to the arms' length sale of Option
Shares (or any other securities into which such Option Shares were converted or
exchanged) to any party not affiliated with Grantee, over (2) the aggregate
purchase price previously paid pursuant hereto by Grantee with respect to such
Option Shares and (B) the net cash amounts, if any, received by Grantee pursuant
to an arms' length sale of a portion of the Option to any party not affiliated
with Grantee.

                  (b) Grantee may exercise its right to surrender the Option and
any Option Shares pursuant to this Section 15 by surrendering to Issuer, at its
principal office, this Agreement together with certificates for Option Shares,
if any, accompanied by a written notice stating (i) that Grantee elects to
surrender the Option and Option Shares, if any, in accordance with the
provisions of this Section 15 and (ii) the Surrender Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

                  (c) To the extent that Issuer is prohibited under applicable
law or regulation from paying the Surrender Price to Grantee in full, Issuer
shall immediately so notify Grantee and thereafter deliver or cause to be
delivered, from time to time, to Grantee, the portion of the Surrender Price
that Issuer is no longer prohibited from paying, within five business days after
the date on which Issuer is no longer so prohibited, provided, however, that if
Issuer at any time after delivery of a notice of surrender pursuant to paragraph
(b) of this Section 15 is prohibited under applicable law or regulation from
paying to Grantee the Surrender Price in full (i) Issuer shall (A) use its
reasonable best efforts to obtain all required regulatory and legal

                                       14

<PAGE>

approvals and to file any required notices as promptly as practicable in order
to make such payments, (B) within five days of the submission or receipt of any
documents relating to any such regulatory and legal approvals, provide Grantee
with copies of the same, and (C) keep Grantee advised of both the status of any
such request for regulatory and legal approvals, as well as any discussions with
any relevant regulatory or other third party reasonably related to the same and
(ii) Grantee may revoke such notice of surrender by delivery of a notice of
revocation to Issuer and, upon delivery of such notice of revocation, the
Exercise Termination Date shall be extended to a date six months from the date
on which the Exercise Termination Date would have occurred if not for the
provisions of this Section 15(c) (during which period Grantee may exercise any
of its rights hereunder, including any and all rights pursuant to this Section
15).

                  (d) Grantee shall have rights substantially identical to those
set forth in paragraphs (a), (b) and (c) of this Section 15 with respect to the
Substitute Option and the Substitute Option Issuer during any period in which
the Substitute Option Issuer would be required to repurchase the Substitute
option pursuant to Section 9.

         16.      (a) Notwithstanding any other provision of this Agreement,
this Option may not be exercised for a number of shares as would, as of the date
of exercise, result in a Notional Total Profit (as defined below) of more than
$77.4 million; provided that nothing in this sentence shall restrict any
exercise of the Option permitted hereby on any subsequent date.

                  (b) As used herein, the term "Notional Total Profit" with
respect to any number of shares as to which Grantee may propose to exercise this
Option shall be the Total Profit (as defined below) determined as of the date of
such proposed exercise assuming that this Option were exercised on such date for
such number of shares and assuming that such shares, together with all other
Option Shares held by Grantee and its affiliates as of such date, were sold for
cash at the closing market price for the Common Stock as of the close of
business on the preceding trading day (less customary brokerage commissions).

                  (c) As used herein, the term "Total Profit" shall mean the
aggregate amount (before taxes) of the following: (i) the amount received by
Grantee pursuant to Issuer's repurchase of the Option (or any portion thereof)
pursuant to Section 7, (ii) (x) the amount received by Grantee pursuant to
Issuer's repurchase of Option Shares (or any portion thereof) pursuant to
Section 7, less (y) the Grantee's purchase price for such Option Shares, (iii)
the net cash amounts received by Grantee pursuant to the sale of Option Shares
(or any other securities into which such Option Shares are converted or
exchanged) to any unaffiliated party, less (y) the Grantee's purchase price of
such Option Shares, (iv) any amounts received by Grantee on the transfer of the
Option (or any portion thereof) to any unaffiliated party, and (v) any amount
equivalent to the foregoing with respect to the Substitute Option.

         17. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties

                                       15

<PAGE>

hereto shall be enforceable by either party hereto through injunctive or other
equitable relief.

         18. If any term, provision, covenant or restriction contained in this
Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or invalidated. If for any reason such court or regulatory agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 7, the full number of shares of Common Stock
provided in Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5
hereof), it is the express intention of Issuer to allow the Holder to acquire or
to require Issuer to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof.

         19. All notices, requests, claims, demands and other communications
hereunder shall be deemed to have been duly given when delivered in person, by
cable, telegram, telecopy or telex, or by registered or certified mail (postage
prepaid, return receipt requested) at the respective addresses of the parties
set forth in the Merger Agreement.

         20. This Agreement shall be governed by and construed in accordance
with the laws of the Commonwealth of Massachusetts regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.

         21. This Agreement may be executed in two or more counterparts, each of
which shall be deemed to be an original, but all of which shall constitute one
and the same agreement.

         22. Except as otherwise expressly provided herein, each of the parties
hereto shall bear and pay all costs and expenses incurred by it or on its behalf
in connection with the transactions contemplated hereunder, including fees and
expenses of its own financial consultants, investment bankers, accountants and
counsel.

         23. Except as otherwise expressly provided herein or in the Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereof, written or oral. The terms
and conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assigns.

                             STOCKHOLDERS AGREEMENT

         Agreement dated as of June 21, 1999 (the "Agreement"), by and between
Citizens Financial Group, Inc., a Delaware corporation (the "Buyer"), and the
undersigned Director and/or Officer of UST Corp., a Massachusetts corporation
(the "Seller").

         WHEREAS, the Buyer and the Seller have entered into an Agreement and
Plan of Merger, dated as of June 21, 1999, as such agreement may be subsequently
amended or modified (the "Agreement and Plan of Merger"), providing for the
merger of a subsidiary of the Buyer with and into the Seller (the "Merger"); and

         WHEREAS, the undersigned (the "Stockholder") beneficially owns and has
sole or shared voting power with respect to the number of shares of the common
stock, par value $0.625 per share (the "Shares"), of the Seller, and holds stock
options or other rights to acquire the number of Shares indicated opposite the
Stockholder's name on Schedule 1 attached hereto.

         WHEREAS, it is a condition to the consummation of the Merger that the
undersigned Stockholder of the Seller execute and deliver this Agreement; and

         NOW, THEREFORE, in consideration of, and as a condition to, the Buyer's
entering into the Agreement and Plan of Merger, and in consideration of the
expenses incurred and to be incurred by the Buyer in connection therewith, the
undersigned Stockholder and the Buyer agree as follows:

         1. The Stockholder, while this Agreement is in effect, shall vote or
cause to be voted all of the Shares that such Stockholder shall be entitled to
so vote, whether such Shares are beneficially owned by such Stockholder on the
date of this Agreement or are subsequently acquired, at the special meeting of
the Seller's stockholders to be called and held following the date hereof (the
"Special Meeting"), for the approval of the Agreement and Plan of Merger and the
Merger and shall vote or cause to be voted all such Shares, at the Special
Meeting or any other meeting of the Seller's stockholders following the date
hereof, against the approval of any other agreement providing for a merger,
acquisition, consolidation, sale of a material amount of assets or other
business combination of the Seller or any of its subsidiaries with any person or
entity other than the Buyer, or any subsidiary of the Buyer.

         2. Prior to the Special Meeting, the Stockholder will not sell, assign,
transfer or otherwise dispose of (including, without limitation, by the creation
of a Lien (as defined in paragraph 3 below)), or permit to be sold, assigned,
transferred or otherwise disposed of, any Shares owned by the Stockholder,
whether such Shares are held by the Stockholder on the date of this Agreement or
are subsequently acquired prior to the Special Meeting, whether by the exercise
of any stock options to acquire Shares or otherwise, except (a) transfers by
will or by operation of law, in which case this Agreement shall bind the
transferee, (b) transfers pursuant to any pledge agreement, subject to the
pledgee agreeing in writing to be bound by the terms of

                                       -1-

<PAGE>

this Agreement, (c) transfers in connection with estate and tax planning
purposes, including transfers to relatives, trusts and charitable organizations,
subject to the transferee agreeing in writing to be bound by the terms of this
Agreement, (d) transfers to any other stockholder of the Seller who has executed
a copy of this Agreement on the date hereof with respect to some or all of the
Shares held by such stockholder, and (e) as the Buyer may otherwise agree in its
sole discretion.

The Seller shall cause its transfer agent to note on its records for the Seller
(in whatever form maintained) that such Shares are subject to the restrictions
on voting and transfer set forth herein, and at Buyer's request shall have any
existing certificates representing Shares subject to this Agreement canceled and
reissued bearing the following legend:

         "THIS CERTIFICATE, AND THE SHARES REPRESENTED HEREBY,
         ARE SUBJECT TO CERTAIN VOTING AND TRANSFER RESTRICTIONS
         CONTAINED IN A STOCKHOLDERS AGREEMENT BY AND BETWEEN
         CITIZENS FINANCIAL GROUP, INC. AND THE BENEFICIAL OWNER
         OF THESE SHARES AND MAY BE TRANSFERRED ONLY IN
         COMPLIANCE THEREWITH.  COPIES OF THE ABOVE-REFERENCED
         AGREEMENT ARE ON FILE AT THE OFFICES OF UST CORP."

         3. The Stockholder represents that the Stockholder has the complete and
unrestricted power and the unqualified right to enter into and perform the terms
of this Agreement. The Stockholder further represents that this Agreement
(assuming this Agreement constitutes a valid and binding agreement of the Buyer)
constitutes a valid and binding agreement with respect to the Stockholder,
enforceable against the Stockholder in accordance with its terms, except as
enforcement may be limited by general principles of equity whether applied in a
court of law or a court of equity and by bankruptcy, insolvency and similar laws
affecting creditors' rights and remedies generally. Except as set forth on
Schedule 1, the Stockholder represents that the Stockholder beneficially owns
the number of Shares indicated opposite such Stockholder's name on said Schedule
1, free and clear of any liens, claims, charges or other encumbrances or
restrictions of any kind whatsoever ("Liens"), and has sole or shared, and
otherwise unrestricted, voting power with respect to such Shares.

         4. The agreement with respect to voting contained in Section 1 hereof
shall remain in full force and effect until the earlier of (i) the consummation
of the Merger or (ii) the termination of the Agreement and Plan of Merger in
accordance with Article VIII thereof and the agreement with respect to transfer
contained in Section 2 hereof shall remain in full force and effect until the
earlier of (i) the Special Meeting or (ii) the termination of the Agreement and
Plan of Merger in accordance with Article VIII thereof.

         5. The Stockholder has signed this Agreement intending to be bound
thereby. The Stockholder expressly agrees that this Agreement shall be
specifically enforceable in any court of competent jurisdiction in accordance
with its terms against the Stockholder. All of the

                                       -2-

<PAGE>

covenants and agreements contained in this Agreement shall be binding upon, and
inure to the benefit of, the respective parties and their permitted successors,
assigns, heirs, executors, administrators and other legal representatives, as
the case may be.

         6. This Agreement may be executed in one or more counterparts, each of
which will be deemed an original but all of which together shall constitute one
and the same instrument.

         7. No waivers of any breach of this Agreement extended by the Buyer to
the Stockholder shall be construed as a waiver of any rights or remedies of the
Buyer with respect to any other stockholder of the Seller who has executed a
copy of this Agreement with respect to Shares held by such stockholder or with
respect to any subsequent breach of the Stockholder or any other such
stockholder of the Seller.

         8. This Agreement is deemed to be signed as a sealed instrument and is
to be governed by the laws of the Commonwealth of Massachusetts, without giving
effect to the principles of conflicts of laws thereof. If any provision hereof
is deemed unenforceable, the enforceability of the other provisions hereof shall
not be affected.
