       [FLEET LOGO]      STERLING BANCSHARES CORPORATION
                                ONE MOODY STREET
                          WALTHAM, MASSACHUSETTS 02154
 
   
                                                                February 8, 1994
    
 
Dear Holder of Sterling Common Stock:
 
   
     You are cordially invited to attend a Special Meeting of the Stockholders
(the "Special Meeting") of Sterling Bancshares Corporation, a Delaware
corporation ("Sterling"), to be held on Wednesday, March 16, 1994, at 9:00 a.m.
at the Charles River Museum of Industry, 154 Moody Street, Waltham,
Massachusetts.
    
 
   
     At the Special Meeting, holders of the outstanding shares of common stock,
par value $.10 per share, of Sterling ("Sterling Common Stock") will be asked to
consider and vote upon a proposal to approve and adopt an Agreement and Plan of
Merger dated as of October 11, 1993 (the "Merger Agreement"), by and between
Sterling and Fleet Financial Group, Inc., a Rhode Island corporation ("Fleet"),
and each of the transactions contemplated thereby, pursuant to which Sterling
will be merged with and into Fleet (the "Merger"). A copy of the Merger
Agreement is attached to the accompanying Proxy Statement-Prospectus as Exhibit
A.
    
 
     Upon consummation of the Merger, each outstanding share of Sterling Common
Stock, except for shares held by Fleet or its subsidiaries or by Sterling or its
subsidiaries (other than in both cases shares held in a fiduciary capacity or as
a result of debts previously contracted), will be converted into the right to
receive the number of shares of Fleet common stock, $1.00 par value ("Fleet
Common Stock"), determined by dividing $39.50 by the Average Closing Price,
subject to adjustment as described in the next paragraph (the "Exchange Ratio").
The "Average Closing Price" is the average closing sale price per share of Fleet
Common Stock on the New York Stock Exchange (as reported by The Wall Street
Journal or, if not reported thereby, another authoritative source), for the 20
New York Stock Exchange trading days ending on the tenth business day after the
date on which the last of the regulatory approvals required to consummate the
transactions contemplated by the Merger Agreement is obtained.
 
     Notwithstanding the foregoing paragraph, if the Average Closing Price is
equal to or greater than $39.24, the Exchange Ratio will be 1.0066; and if the
Average Closing Price is equal to or less than $29.01, the Exchange Ratio will
be 1.3616; except that if the Average Closing Price is equal to or less than
$25.59, Sterling shall have the right, waivable by it, to terminate the Merger
Agreement, unless Fleet shall have elected, at its option, to adopt as the
Exchange Ratio the "Adjusted Maximum Exchange Ratio", which shall be determined
by dividing $34.84 by the Average Closing Price.
 
   
     Enclosed are a Notice of Special Meeting of Stockholders and a Proxy
Statement-Prospectus which describe the Merger, the background to the
transaction and the businesses of Fleet and Sterling. You are urged to read all
these materials carefully. The Board of Directors has fixed the close of
business on February 3, 1994 as the record date for the Special Meeting.
Accordingly, only stockholders of record on that date will be entitled to notice
of, and to vote at, the Special Meeting or any adjournments or postponements
thereof. The affirmative vote of the holders of a majority of the shares of
Sterling Common Stock outstanding and entitled to vote is necessary to approve
and adopt the Merger Agreement.
    
 
   
     THE BOARD OF DIRECTORS HAS UNANIMOUSLY ADOPTED A RESOLUTION APPROVING THE
MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE IN FAVOR OF
APPROVING AND ADOPTING THE MERGER AGREEMENT. Keefe, Bruyette & Woods, Inc.
("KBW"), Sterling's financial advisor, has rendered a written opinion to the
Board of Directors of Sterling that states, among other things, that, as of the
date of this Proxy Statement-Prospectus, the Exchange Ratio is fair to
Sterling's stockholders from a financial point of view. The written opinion of
KBW, dated the date of this Proxy Statement-Prospectus, is reproduced in full as
Exhibit C to the accompanying Proxy Statement-Prospectus, and I urge you to read
the opinion carefully.
    
 
     Holders of shares of Sterling Common Stock do not have any appraisal rights
under Delaware law in connection with the Merger.

     A form of proxy solicited by the Board of Directors is enclosed for your
convenience. YOU ARE REQUESTED TO COMPLETE, DATE, SIGN AND RETURN THE ENCLOSED
PROXY CARD IN THE ENCLOSED ENVELOPE WHICH REQUIRES NO POSTAGE IF MAILED IN THE
UNITED STATES. If you attend the Special Meeting, you may vote in person if you
wish, even if you have previously returned your proxy card.
 
     Promptly after the Merger, a letter of transmittal will be mailed to all
holders of record of shares of Sterling Common Stock to use in connection with
surrendering their stock certificates. PLEASE DO NOT SEND YOUR STOCK
CERTIFICATES WITH THE ENCLOSED PROXY CARD OR TO THE EXCHANGE AGENT UNTIL YOU
RECEIVE THE LETTER OF TRANSMITTAL, WHICH WILL INCLUDE INSTRUCTIONS AS TO THE
PROCEDURE TO BE USED IN SENDING YOUR STOCK CERTIFICATES.
 
     I strongly support the Merger of Sterling with Fleet and join with the
other members of the Board in recommending the Merger to you. We urge you to
vote in favor of approval and adoption of the Merger Agreement. If you should
have any questions about the Merger or need assistance in completing your proxy
card, please contact John F. Treanor at Sterling at (617) 894-7790.
 
                                          Very truly yours,
 
                                          JOHN C. WARREN
                                          Chairman of the Board,
                                          President and Chief Executive
                                          Officer
 
   
     IT IS IMPORTANT THAT YOUR SHARES BE REPRESENTED AT THE SPECIAL MEETING.
WHETHER OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING, YOU ARE REQUESTED TO
COMPLETE, DATE, SIGN AND RETURN THE ENCLOSED PROXY CARD IN THE ENCLOSED ENVELOPE
WHICH REQUIRES NO POSTAGE IF MAILED IN THE UNITED STATES. IF YOU ATTEND THE
SPECIAL MEETING, YOU MAY VOTE IN PERSON IF YOU WISH, EVEN IF YOU HAVE PREVIOUSLY
RETURNED YOUR PROXY CARD.
    
 
     STERLING STOCK CERTIFICATES SHOULD NOT BE FORWARDED TO THE EXCHANGE AGENT
UNTIL A STERLING STOCKHOLDER HAS RECEIVED A TRANSMITTAL FORM AND SHOULD NOT BE
RETURNED WITH THE ENCLOSED PROXY.

                        STERLING BANCSHARES CORPORATION
   
                                 MARCH 16, 1994
    
 
   
    This Proxy Statement-Prospectus is furnished in connection with the
solicitation of proxies by the Board of Directors of Sterling Bancshares
Corporation ("Sterling") to be used at a Special Meeting of stockholders to be
held on March 16, 1994 (the "Special Meeting") for the purpose of considering
and voting upon a proposal to approve and adopt an Agreement and Plan of Merger
(the "Merger Agreement") dated as of October 11, 1993, by and between Sterling
and Fleet Financial Group, Inc. ("Fleet") providing for the merger of Sterling
with and into Fleet (the "Merger"). The Merger Agreement is attached hereto as
Exhibit A and is incorporated herein by reference. Although not a condition to
the consummation of the Merger, the Merger Agreement also contemplates that
immediately upon consummation of the Merger, Sterling Bank, a wholly-owned
subsidiary of Sterling (the "Bank"), will merge (the "Bank Merger") with and
into Fleet Bank of Massachusetts, National Association (the "Surviving Bank"),
an indirect wholly-owned subsidiary of Fleet, pursuant to a Bank Agreement and
Plan of Merger (the "Bank Merger Agreement") to be entered into between the Bank
and the Surviving Bank. See "THE MERGER -- Structure of the Bank Merger". This
Proxy Statement-Prospectus and the form of proxy are first being mailed to
stockholders of Sterling on or about February 8, 1994.
    
 
    At the Effective Time (as defined below) of the Merger, each Sterling
stockholder will receive, for each share of Sterling common stock, $0.10 par
value ("Sterling Common Stock") they hold, except for shares held by Fleet or
its subsidiaries or by Sterling or its subsidiaries (other than in both cases
shares held in a fiduciary capacity or as a result of debts previously
contracted), Fleet common stock, $1.00 par value (including the associated
preferred share purchase rights described in "DESCRIPTION OF FLEET CAPITAL
STOCK -- Fleet Common Stock -- Preferred Share Purchase Rights") ("Fleet Common
Stock"), based on an exchange ratio linked to the average closing price of Fleet
Common Stock, subject to certain adjustments. No fractional shares of Fleet
Common Stock will be issued and cash will be paid in lieu thereof. See "THE
MERGER -- Exchange Ratio and Other Matters" and "DESCRIPTION OF FLEET CAPITAL
STOCK -- Fleet Common Stock".
 
   
    Fleet has filed a Registration Statement on Form S-4 under the Securities
Act of 1933, as amended (the "Securities Act"), with the Securities and Exchange
Commission (the "Commission") covering a maximum of 7,597,272 shares of Fleet
Common Stock, representing shares to be issued in connection with the Merger,
including shares issuable upon the exercise of options to acquire Sterling
Common Stock granted pursuant to the Sterling Amended and Restated Stock Option
Plan. See "THE MERGER -- Effect on Employee Benefits". This Proxy
Statement-Prospectus also constitutes the Prospectus of Fleet filed as a part of
such Registration Statement.
    
 
   
    Contemporaneously with entering into the Merger Agreement, Sterling granted
Fleet an option (the "Option") to purchase up to 512,943 shares of Sterling
Common Stock, representing 17.0% of the outstanding shares of Sterling Common
Stock as of October 11, 1993 before giving effect to the exercise of the Option.
The number of shares to be issued pursuant to the Option is subject to
adjustment under certain circumstances. The Option was granted by Sterling to

1993 (the "Stock Option Agreement"), between Sterling and Fleet, and was
required by Fleet as an inducement and condition to entering into the Merger
Agreement. The Option is exercisable by Fleet, upon the occurrence of certain
events described in the Stock Option Agreement, at an exercise price of $30.50
per share payable in cash. On October 8, 1993, the business day immediately
preceding the public announcement of the proposed Merger, the closing price for
Sterling Common Stock was $30.50. For a discussion of other terms of the Stock
Option Agreement, including provisions regarding repurchase and termination of
the Option, see "THE MERGER -- Stock Option Agreement". A copy of the Stock
Option Agreement is attached to this Proxy Statement-Prospectus as Exhibit B.

     The Special Meeting will be held at the Charles River Museum of Industry,
154 Moody Street, Waltham, Massachusetts, at 9:00 a.m. on Wednesday, March 16,
1994.
    
 
PURPOSES OF SPECIAL MEETING
 
     The Special Meeting will be held for the purpose of considering and voting
upon a proposal to adopt and approve the Merger Agreement and the transactions
contemplated thereby, and to conduct any other business that may properly come
before the Special Meeting, or any adjournments or postponements thereof. See
"MEETING INFORMATION -- The Special Meeting".
 
                                        5
<PAGE>   11
 
VOTES REQUIRED
 
   
     The Board of Directors has fixed the close of business on February 3, 1994
as the record date (the "Record Date") for the determination of stockholders
entitled to notice of and to vote at the Special Meeting. Only the holders of
record of the outstanding shares of Sterling Common Stock on the Record Date
will be entitled to notice of, and to vote at, the Special Meeting and any
adjournments or postponements thereof. The presence, in person or by proxy, of a
majority of the aggregate number of shares of Sterling Common Stock outstanding
and entitled to vote on the Record Date is necessary to constitute a quorum at
the Special Meeting.
    
 
   
     At December 31, 1993, 3,045,031 shares of Sterling Common Stock were
outstanding and entitled to vote, of which approximately 318,582 shares, or
approximately 10.46%, were held by directors and executive officers of Sterling
and their respective affiliates. Each such director and officer of Sterling has
indicated his or her intention to vote the Sterling Common Stock beneficially
owned by him or her for approval of the Merger Agreement. The affirmative vote
of the holders of a majority of the shares of Sterling Common Stock issued,
outstanding and entitled to vote at the Special Meeting will be required to
approve the Merger Agreement. Consequently, assuming, for illustration purposes
only, that the number of outstanding shares of Sterling Common Stock and the
number of such shares held by directors and officers of Sterling and their
affiliates remains unchanged between December 31, 1993, and the Record Date and
that each director and officer of Sterling and their respective affiliates votes
in favor of the Merger Agreement, the affirmative vote of holders of
approximately 1,203,934 additional shares of Sterling Common Stock, representing
approximately 39.54% of the shares issued and outstanding on December 31, 1993,
will be required. The approval of the Merger Agreement by Sterling's
stockholders is a condition to the consummation of the Merger.
    
 
     See "MEETING INFORMATION -- Votes Required".
 
TERMS OF THE MERGER
 
   
     In the Merger, each share of Sterling Common Stock outstanding (other than
shares (a) held by Sterling as treasury stock or (b) held by Fleet or Sterling
or any subsidiary thereof (other than in both cases shares held in a fiduciary
capacity or as a result of debts previously contracted)) will be converted into
and exchangeable for the number of shares (the "Exchange Ratio") of Fleet Common
Stock determined by dividing $39.50 by the Average Closing Price (as defined
below); provided, that (i) if the Average Closing Price is equal to or greater
than $39.24, the Exchange Ratio shall be 1.0066 (the "Minimum Exchange Ratio")
and (ii) if the Average Closing Price is equal to or less than $29.01, the
Exchange Ratio shall be 1.3616 (the "Maximum Exchange Ratio"); and provided,
further, that if the Average Closing Price is equal to or less than $25.59,
Sterling shall have the right, waivable by it, to terminate the Merger
Agreement, unless Fleet elects, at its option, to adopt as the Exchange Ratio
the "Adjusted Maximum Exchange Ratio" which shall be determined by dividing
$34.84 by the Average Closing Price. The "Average Closing Price" is defined in
the Merger Agreement as the average closing sale price per share of Fleet Common
Stock on the Stock Exchange (as reported by The Wall Street Journal or, if not
reported thereby, another authoritative source), for the twenty (20) Stock
Exchange trading days ending on the tenth business day after the date on which
the last of the regulatory approvals required to consummate the transactions
contemplated by the Merger Agreement is obtained. See "THE MERGER -- Regulatory
Matters". The Exchange Ratio is the product of arms' length negotiations between
the respective management of Fleet and Sterling. In negotiating the Exchange
Ratio, the management of Sterling had the benefit of advice from its financial
advisor, the investment banking firm of Keefe, Bruyette & Woods, Inc. ("KBW").
See "THE MERGER -- Opinion of Financial Advisor".
    
 
   
     No fractional shares of Fleet Common Stock will be issued in the Merger. In
lieu thereof, each holder of Sterling Common Stock who otherwise would have been
entitled to a fractional share of Fleet Common Stock will receive cash in an
amount equal to such fraction multiplied by the closing sale price of Fleet
Common Stock on the Stock Exchange as reported by The Wall Street Journal for
the Stock Exchange trading day immediately preceding the date of the Effective
Time. Calculations will be made to the nearest one-thousandth of a share of
Fleet Common Stock and to the nearest cent.
    
 
                                        6
<PAGE>   12
 
   
     The Merger will become effective on the date and time (the "Effective
Time") as set forth in the certificate of merger which shall be filed with the
Secretary of State of Delaware and the articles of merger which shall be filed
with the Secretary of State of Rhode Island.
    
 
   
     At the Effective Time, all stock options with respect to Sterling Common
Stock granted by Sterling under Sterling's Amended and Restated Stock Option
Plan (the "Sterling Stock Option Plan"), which are outstanding at such time,
whether or not then exercisable, will be converted into and will become options
under Fleet's 1992 Employee Stock Option and Restricted Stock Plan (the "Fleet
Stock Option Plan") to purchase Fleet Common Stock. The rights to Fleet Common
Stock to be received by holders of Sterling stock options upon consummation of
the Merger will be the same as the rights such optionees had under the Sterling
Stock Option Plan immediately prior to the Effective Time, except that the
number of shares of Fleet Common Stock subject to such options and the exercise
price of such options will be adjusted to give effect to the Exchange Ratio.
    
 
   
     Using the $35.25 closing price for Fleet Common Stock on February 1, 1994
and 3,119,822 shares of Sterling Common Stock outstanding on such date and
assuming, for illustration purposes only, that such price and number of shares
constitutes the Average Closing Price and number of outstanding shares of
Sterling Common Stock exchangeable for Fleet Common Stock at the Effective Time,
the Exchange Ratio would be 1.1206 and Fleet would issue approximately 3,496,073
shares of Fleet Common Stock to acquire 3,119,822 shares of Sterling Common
Stock. In addition, again assuming, for illustration purposes only, that the
Exchange Ratio is 1.1206 and that the number of shares of Sterling Common Stock
issuable at the Effective Time upon the exercise of outstanding options granted
pursuant to the Sterling Stock Option Plan remains unchanged from February 1,
1994, options to acquire 157,864 shares of Sterling Common Stock would be
converted into options to acquire 176,902 shares of Fleet Common Stock, at
various exercise prices, adjusted to give effect to the Exchange Ratio. Under
such circumstances, immediately after the Effective Time, former Sterling
stockholders would hold approximately 2.48% of the outstanding shares of Fleet
Common Stock (assuming that 140,994,984 shares of Fleet Common Stock were
outstanding immediately after the Effective Time, which amount includes
137,498,911 shares of Fleet Common Stock outstanding as of February 1, 1994 and
3,496,073 shares of Fleet Common Stock issued to Sterling stockholders in the
Merger, but does not include existing Fleet options to acquire Fleet Common
Stock or options to acquire Fleet Common Stock issued in the Merger to optionees
under the Sterling Stock Option Plan) and the Merger would be valued at
approximately $123.2 million ($129.5 million including options to acquire Fleet
Common Stock issued in the Merger to optionees under the Sterling Stock Option
Plan).
    
 
     Although not a condition to the consummation of the Merger, the Merger
Agreement contemplates that immediately following the consummation of the
Merger, the Bank will merge with and into the Surviving Bank.
 
   
     See "THE MERGER -- Opinion of Financial Advisor", "-- Exchange Ratio and
Other Matters", "-- Structure of the Bank Merger", "-- Regulatory Matters" and
"-- No Appraisal Rights".
    
 
STOCK OPTION AGREEMENT
 
   
     Pursuant to the Stock Option Agreement, Sterling granted Fleet the Option
to purchase up to 512,943 fully paid and non-assessable shares of Sterling
Common Stock, representing 17% of the shares of Sterling Common Stock issued and
outstanding as of October 11, 1993, without giving effect to the exercise of the
Option, for $30.50 per share. The number of shares is subject to upward
adjustment to 17% of the number of shares of Sterling Common Stock issued and
outstanding, without giving effect to the exercise of the Option, in the event
that additional shares of Sterling Common Stock are issued or otherwise become
outstanding after October 11, 1993 (other than pursuant to the exercise of the
Option or in the event of certain events such as a stock dividend for which a
separate adjustment mechanism is provided). The Option is exercisable in certain
circumstances that create the potential for another party to acquire control of
Sterling and was requested by Fleet to increase the likelihood that the Merger
will be consummated by making it more difficult and more expensive for a third
party to attempt to acquire control of Sterling.

RECOMMENDATION OF THE BOARD OF DIRECTORS AND REASONS FOR THE MERGER
    
 
   
     THE BOARD OF DIRECTORS OF STERLING HAS UNANIMOUSLY ADOPTED A RESOLUTION
APPROVING THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS APPROVAL AND ADOPTION
OF THE MERGER AGREEMENT BY STERLING'S STOCKHOLDERS. Sterling's Board has adopted
that resolution and makes that recommendation because it believes that the terms
of the Merger Agreement are fair and in the best interests of Sterling and its
stockholders and because the Sterling Board believes in its business judgment
that the Exchange Ratio is fair and reasonable to the stockholders of Sterling.
The terms of the Merger Agreement, including the Exchange Ratio and the Stock
Option Agreement, were reached on the basis of arms' length negotiations between
Sterling and Fleet. In the course of reaching its decision to approve the Merger
Agreement, the Board of Directors of Sterling consulted with its legal advisors
regarding the legal terms of the Merger Agreement and Stock Option Agreement and
the Board of Directors' obligations in its consideration thereof and with KBW,
its financial advisor, regarding the financial terms and fairness, from a
financial point of view, of the Exchange Ratio in the proposed Merger.
    
 
   
     See "THE MERGER -- Background of the Merger" and "-- Recommendation of the
Board of Directors and Reasons for the Merger".
    
 
   
OPINION OF FINANCIAL ADVISOR
    
 
     KBW has delivered to the Board of Directors of Sterling its oral opinion,
as of October 10, 1993 and its written opinion, as of the date of this Proxy
Statement-Prospectus, that the Exchange Ratio is fair, from a financial point of
view, to Sterling's stockholders. The full text of the opinion of KBW dated as
of the date of this Proxy Statement-Prospectus, which sets forth assumptions
made, matters considered and limits on the review undertaken by KBW, is attached
hereto as Exhibit C. Stockholders are urged to read this opinion in its
entirety. KBW's opinion is directed only to the Exchange Ratio and does not
constitute a recommendation to any Sterling stockholder as to how such
stockholder should vote at the Special Meeting.
 
     See "THE MERGER -- Background of the Merger", "-- Opinion of Financial
Advisor" and Exhibit C to this Proxy Statement-Prospectus.
 
   
CONDITIONS TO THE CONSUMMATION OF THE MERGER
    
 
   
     Consummation of the Merger is subject to various conditions, including the
approval of Sterling's stockholders solicited hereby; the effectiveness of the
Registration Statement of which this Proxy Statement-Prospectus forms a part;
approval by certain federal and Massachusetts regulatory authorities; receipt by
Sterling of an opinion of counsel as to the tax-free nature of the Merger for
federal income tax purposes (except for cash received in lieu of fractional
shares); receipt of a letter from each of Fleet's and Sterling's independent
accountants to the effect that the Merger qualifies to be accounted for as a
pooling-of-interests; the listing, subject to notice of issuance, on the Stock
Exchange of the Fleet Common Stock to be issued in the Merger; and other
customary closing conditions. None of the foregoing approvals has been obtained
and there is no assurance that such approvals will be obtained or as to the
timing of such approvals.
    
 
     See "THE MERGER -- Conditions to the Consummation of the Merger" and
"-- Regulatory Matters".
 
TERMINATION OF THE MERGER AGREEMENT; AMENDMENT OR WAIVER OF THE MERGER AGREEMENT
 
   
     The Merger Agreement may be abandoned at any time prior to the Effective
Time by the mutual consent of Fleet and Sterling by a majority vote of the
members of each company's entire Board of Directors. Subject to certain
limitations in cases where the party seeking termination is in breach of the
Merger Agreement, the Merger Agreement may also be terminated by either Fleet or
Sterling, acting individually, (a) forty-five days after the date on which any
request or application for regulatory approval required to consummate the Merger
shall have been denied or withdrawn at the request or recommendation of any
governmental entity which must grant such regulatory approval, unless within the
forty-five day period following such denial or withdrawal a petition for
rehearing or an amended application has been filed with such governmental
entity; (b) if any
    
 
                                        8
<PAGE>   14
 
   
governmental entity shall have issued a final nonappealable order enjoining or
otherwise prohibiting the consummation of any of the transactions contemplated
by the Merger Agreement; (c) if the Effective Time has not occurred by September
30, 1994; (d) if there is a material breach by the other party of any
representation, warranty, covenant or agreement contained in the Merger
Agreement which is not timely cured; or (e) if the vote of Sterling's
stockholders required to approve the Merger Agreement is not obtained. Sterling
may also terminate the Merger Agreement in the event the Average Closing Price
is equal to or less than $25.59, unless Fleet elects to adopt the Adjusted
Maximum Exchange Ratio as the Exchange Ratio.
    
   
     See "THE MERGER -- Termination of the Merger Agreement".

WAIVER
    
   
     Fleet and Sterling, with the authorization of their respective Boards of
Directors, may, to the extent legally allowable, (a) extend the time for the
performance of any of the obligations or other acts required of the other party
contained in the Merger Agreement; (b) waive any inaccuracies in the
representations and warranties of the other party contained in the Merger
Agreement or in any document delivered pursuant to the Merger Agreement; or (c)
waive compliance by the other party of any of its agreements or conditions
contained in the Merger Agreement, except that after Sterling stockholder
approval, no extension or waiver shall reduce the amount or change the form of
consideration to be delivered to each of Sterling's stockholders as contemplated
by the Merger Agreement without further approval of Sterling's stockholders,
except as contemplated by the Merger Agreement.
    
   
     See "THE MERGER -- Waiver and Amendment to the Merger Agreement".
 
AMENDMENT
    
   
     Any term or provision of the Merger Agreement may be amended in writing
(subject to compliance with applicable law) at any time, except that after
Sterling stockholder approval, no amendment shall reduce the amount or change
the form of the consideration to be delivered to each of Sterling's stockholders
under the Merger Agreement other than as contemplated by the Merger Agreement.
In addition, Delaware law prohibits, among other things, any change any of the
terms and conditions of the Merger Agreement if such change or alteration would
adversely affect any holder of Sterling Common Stock.
    
   
     See "THE MERGER -- Exchange Ratio and Other Matters", "-- Termination of
the Merger Agreement" and "-- Waiver and Amendment of the Merger Agreement".
    
   
REGULATORY APPROVALS
    
   
     The Merger is subject to approval by the Board of Governors of the Federal
Reserve System (the "Federal Reserve Board") pursuant to Section 3 of the Bank
Holding Company Act of 1956, as amended, and by the Board of Bank Incorporation
of the Commonwealth of Massachusetts (the "Massachusetts BBI") under Sections 2
and 4 of Chapter 167A of the Massachusetts General Laws. Assuming Federal
Reserve Board approval, the Merger may not be consummated for 30 days after such
approval, during which time the United States Department of Justice may
challenge the Merger on antitrust grounds. Fleet has filed a draft application
with the Federal Reserve Board and intends to file an application with the
Massachusetts BBI after the date hereof, in each case with respect to the Merger
(as well as with respect to its right to exercise the Option). The Merger will
not proceed until all regulatory approvals required to consummate the Merger
have been obtained, such approvals are in full force and effect and all
statutory waiting periods in respect thereof have expired. There can be no
assurance that the Merger will be approved by the Federal Reserve Board or the
Massachusetts BBI. If such approvals are received, there can be no assurance as
to the date of such approvals or the absence of any litigation challenging such
approvals. See "THE MERGER -- Regulatory Matters".
    
 
     While it is not a condition to the consummation of the Merger, the Merger
Agreement contemplates that the Bank Merger will take place immediately
following the consummation of the Merger. In order to effect the Bank Merger,
Fleet will need, among other things, the approval of the Office of the
Comptroller of the
 
                                        9
<PAGE>   15
 
   
Currency ("OCC") under the Bank Merger Act. Fleet intends to file an application
for approval of the Bank Merger with the OCC after the date hereof.
    
 
   
     See "THE MERGER -- Structure of the Bank Merger".
    
 
   
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
    
 
   
     Consummation of the Merger is conditioned on there being delivered the
opinion of counsel to Sterling, which may be based on various facts and
representations and subject to various assumptions, dated as of the Effective
Time, to the effect that, among other things, the Merger will constitute a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code"). If the Merger constitutes such a
reorganization, the following would be the material federal income tax
consequences of the Merger in the opinion of counsel to Sterling: (a) no gain or
loss will be recognized by the stockholders of Sterling upon their receipt of
Fleet Common Stock in exchange for their Sterling Common Stock, except in
respect of cash received in lieu of fractional shares; (b) the tax basis of the
shares of Fleet Common Stock received by the stockholders of Sterling will be
the same as the tax basis of the Sterling Common Stock surrendered in exchange
therefor, decreased by the tax basis allocated to any such fractional share
interests; and (c) the holding period of the Fleet Common Stock in the hands of
the Sterling stockholders will generally include the holding period of their
Sterling Common Stock.
    
 
     Stockholders should consult their own tax advisors as to the tax
consequences of the Merger to them under Federal, state, local or any other
applicable law.
 
     See "THE MERGER -- Certain Federal Income Tax Consequences".
 
   
ACCOUNTING
    
 
     The Merger is intended to be accounted for as a pooling-of-interests, as
more fully described under "THE MERGER -- Accounting Treatment".
 
   
MANAGEMENT AND OPERATIONS AFTER THE MERGER
    
 
     Upon consummation of the Merger, the directors and officers of Fleet
immediately prior to the Effective Time shall remain the directors and officers
of the surviving corporation, to hold office in accordance with the charter
documents and bylaws of the surviving corporation until their respective
successors are duly elected or appointed and qualified.
 
     See "THE MERGER -- Management and Operations after the Merger".
 
   
NO APPRAISAL RIGHTS
    
 
     Holders of Sterling Common Stock do not have any appraisal rights under
Delaware law in connection with the Merger.
 
   
     See "THE MERGER -- No Appraisal Rights".
    
 
   
CERTAIN DIFFERENCES IN THE RIGHTS OF STOCKHOLDERS
    
 
   
     The rights of stockholders of Sterling are currently governed by the
Delaware General Corporation Law, Sterling's Restated Certificate of
Incorporation, as amended, and Sterling's by-laws. Upon consummation of the
Merger, Sterling's stockholders automatically become stockholders of Fleet, and
their rights will be governed by the Rhode Island Business Corporation Act, the
Fleet Restated Articles of Incorporation and Fleet's by-laws.
    
 
   
     See "COMPARISON OF STOCKHOLDERS' RIGHTS UNDER RHODE ISLAND AND DELAWARE
LAW".

(1) Pro forma primary income per share data has been computed based on the pro
    forma net income available to holders of Fleet Common Stock and Sterling
    Common Stock, using the historical weighted average shares outstanding and
    common stock equivalents relating to stock options, Fleet's Dual Convertible
    Preferred Stock, $1.00 par value (the "Dual Convertible Preferred Stock")
    and rights to acquire Fleet Common Stock issued to holders of the Dual
    Convertible Preferred Stock, each outstanding during the year, adjusted to
    the equivalent number of shares of Fleet Common Stock, and assuming the
    exchange of 1.1206 shares of Fleet Common Stock for each share of Sterling
    Common Stock which would represent the Exchange Ratio, assuming, for
    illustration purposes only, that the Average Closing Price is $35.25, the
    closing price for Fleet Common Stock on February 1, 1994. Pro forma fully
    diluted income per share has been computed as described above with the
    addition, if dilutive, of shares of Fleet Common Stock associated with the
    conversion of Fleet's Series I 12% Cumulative Convertible Preferred Stock,
    $1.00 par value (the "Series I Preferred"), Fleet's Series II 6 1/2%
    Cumulative Convertible Preferred Stock (the "Series II Preferred") and
    Fleet's Dual Convertible Preferred Stock, and the exercise of stock options
    as may be appropriate as of the beginning of the earliest period presented.
    
 
    Earnings used in the calculation of pro forma primary earnings per share are
    adjusted by the dividend requirements of all preferred stocks. Earnings used
    on a pro forma fully diluted basis are adjusted for preferred stock
    dividends and interest on any convertible subordinated debentures as may be
    appropriate.
 
   
(2) Pro forma combined cash dividends declared per share of Fleet Common Stock
    amounts are determined by dividing aggregate pro forma cash dividends
    declared by the equivalent pro forma combined average outstanding shares of
    Fleet Common Stock giving effect to the Merger and the exchange of 1.1206
    shares of Fleet Common Stock for each share of Sterling Common Stock which
    would represent the Exchange Ratio, assuming, for illustration purposes
    only, that the Average Closing Price is $35.25, the closing price for Fleet
    Common Stock on February 1, 1994.
    
 
   
(3) Pro forma combined book values per share represent the book values per share
    giving effect to the Merger and the exchange of 1.1206 shares of Fleet
    Common Stock for each share of Sterling Common Stock which would represent
    the Exchange Ratio, assuming, for illustration purposes only, that the
    Average Closing Price is $35.25, the closing price for Fleet Common Stock on
    February 1, 1994.
    
 
   
(4) Equivalent pro forma income, cash dividends declared, and book value per
    share of Sterling Common Stock represent the income, cash dividends
    declared, and book value per share amounts of Fleet Common Stock on a pro
    forma combined basis multiplied by 1.1206, which would represent the
    Exchange Ratio, assuming, for illustration purposes only, that the Average
    Closing Price is $35.25, the closing price for Fleet Common Stock on
    February 1, 1994. Equivalent market value per share of Sterling Common Stock
    represents the closing sales price of Fleet Common Stock, as reported in The
    Wall Street Journal, on October 8, 1993 (the business day immediately
    preceding the public announcement of the proposed Merger) and February 1,
    1994 multiplied by 1.1575 and 1.1206, respectively, which would represent
    the Exchange Ratio, assuming, for illustration purposes only, that the
    Average Closing Price is $34.125 and $35.25, the closing prices for Fleet
    Common Stock on October 8, 1993 and February 1, 1994, respectively.

 (1) Data for the year ended December 31, 1991 includes results of the banks
     acquired in the Bank of New England acquisition from July 14, 1991. Certain
     1991 amounts have been reclassified to conform to current-year
     presentation.
    
   
 (2) Results for the year ended December 31, 1990 reflect the restatement of
     earnings relating to Fleet's accounting for declines in the market value of
     its marketable equity securities discussed in Fleet's Current Reports on
     Form 8-K dated May 3, 1991 and August 16, 1991 and its Annual Report on
     Form 10-K for the year ended December 31, 1991.
    
   
 (3) For the nine months ended September 30, 1992 and the year ended December
     31, 1992, the minority interest deduction for Fleet Mortgage Group, Inc.
     ("FMG") totalled approximately 19% of FMG's earnings from the date of the
     initial public offering (August 7, 1992) to the end of each respective
     period. For the nine months ended September 30, 1993, such minority
     interest deduction totalled approximately 19% of FMG's earnings for such
     period.
    
 (4) Common stockholders' equity (used to compute book value per common share)
     is equal to the difference between total assets and total liabilities less
     total preferred stockholders' equity. Total assets of Fleet for each
     relevant period-end include goodwill and core deposit intangible. Such
     goodwill and core deposit intangible amounted to $360,793, $341,339,
     $211,731, $229,094 and $242,905, at Decem-

     ber 31, 1992, 1991, 1990, 1989 and 1988, respectively, and $342,278 and
     $314,202 at September 30, 1993 and 1992, respectively.
 
 (5) The common dividend payout ratio is equal to the ratio of aggregate common
     dividends declared during the indicated period to the consolidated net
     income of Fleet during such period. For the year ended December 31, 1990,
     common dividends aggregated $136,665 and the net loss was $73,687.
 
 (6) Earnings consist of income before income taxes plus fixed charges
     (excluding capitalized interest). Fixed charges consist of interest on
     short-term debt and long-term debt (including interest related to
     capitalized leases and capitalized interest) and one-third of rent expense,
     which approximates the interest component of such expense. In addition,
     where indicated, fixed charges include interest on deposits. Fixed charges
     exceeded earnings by $163,323 (excluding interest on deposits) and by
     $163,323 (including interest on deposits) for the year ended December 31,
     1990.
 
 (7) Earnings consist of income before income taxes plus fixed charges
     (excluding capitalized interest) and the pretax equivalent of dividends on
     preferred stock. Fixed charges and dividends on preferred stock consist of
     interest on short-term debt and long-term debt (including interest related
     to capitalized leases and capitalized interest) and one-third of rent
     expense, which approximates the interest component of such expense, plus
     the pretax equivalent of dividends on preferred stock. In addition, where
     indicated, fixed charges include interest on deposits. The sum of fixed
     charges and dividends exceeded earnings by $163,323 (excluding interest on
     deposits) and by $163,323 (including interest on deposits) for the year
     ended December 31, 1990.
 
 (8) For a discussion of Fleet's reclassification in 1992 of its "portfolio
     securities" to "securities held for sale", see Fleet's Current Report on
     Form 8-K dated October 21, 1992.
 
 (9) Short-term borrowings consist mainly of federal funds purchased, securities
     sold under agreements to repurchase, commercial paper, bank debt and the
     current portion of long-term debt.
 
(10) Interim financial percentages have been annualized, where appropriate.
 
   
(11) Excludes $283,000 of Fleet's Dual Convertible Preferred Stock at September
     30, 1992, December 31, 1992 and December 31, 1991 and includes $283,000 of
     Fleet's Dual Convertible Preferred Stock at September 30, 1993. Including
     the $283,000 of Dual Convertible Preferred Stock, this ratio would be
     6.36%, 6.41% and 6.19% at September 30, 1992, December 31, 1992 and
     December 31, 1991, respectively. The Dual Convertible Preferred Stock was
     reclassified to stockholders' equity as of December 31, 1992; accordingly,

                              MEETING INFORMATION
 
THE SPECIAL MEETING
 
   
     This Proxy Statement-Prospectus is being furnished in connection with the
solicitation of proxies by the Board of Directors of Sterling for use at the
Special Meeting. The Special Meeting will be held at the Charles River Museum of
Industry, 154 Moody Street, Waltham, Massachusetts, at 9:00 a.m. on Wednesday,
March 16, 1994.
    
 
   
     The Special Meeting will be held for the purpose of considering and voting
upon a proposal to approve and adopt the Merger Agreement and the transactions
contemplated thereby, and to conduct any other business that may properly come
before the Special Meeting, or any adjournments or postponements thereof. Any
action may be taken on the foregoing proposals at the Special Meeting on the
date specified above, or on any date or dates to which, by original or later
adjournment, the Special Meeting may be adjourned, or to which the Special
Meeting may be postponed.
    
 
     THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY.
 
RECORD DATE
 
   
     The Board of Directors has fixed the close of business on February 3, 1994
as the Record Date. Only the holders of record of the outstanding shares of
Sterling Common Stock on the Record Date will be entitled to notice of, and to
vote at, the Special Meeting and any adjournments or postponements thereof. At
the Record Date, 3,119,822 shares of Sterling Common Stock were outstanding and
entitled to vote. The presence, in person or by proxy, of a majority of the
aggregate number of shares of Sterling Common Stock outstanding and entitled to
vote on the Record Date is necessary to constitute a quorum at the Special
Meeting.
    
 
PROXIES; VOTING AND REVOCATION
 
     Shares represented by a properly executed proxy received prior to the vote
at the Special Meeting and not revoked will be voted at the Special Meeting as
directed in the proxy. IF A PROXY IS SUBMITTED AND NO DIRECTIONS ARE GIVEN, THE
PROXY WILL BE VOTED FOR THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY. Sterling intends to count shares of
Sterling Common Stock present in person at the Special Meeting but not voting,
and shares of Sterling Common Stock for which it has received proxies but with
respect to which holders of shares have abstained on any matter, as present at
the Special Meeting for purposes of determining the presence or absence of a
quorum for the transaction of business. Since the affirmative vote of the
holders of a majority of the outstanding shares of Sterling Common Stock
entitled to vote on the Merger is required to approve and adopt the Merger
Agreement and the transactions contemplated thereby, such abstentions will have
the effect of a negative vote. In addition, under the rules of the National
Association of Securities Dealers, brokers who hold shares in street name for
customers who are the beneficial owners of such shares are prohibited from
giving a proxy to vote shares held for such customers on the approval and
adoption of the Merger Agreement without specific instructions from such
customers. Given that Delaware law requires the affirmative vote of the holders
of a majority of the outstanding shares of Sterling Common Stock entitled to
vote on the Merger Agreement in order to adopt such Merger Agreement, the
failure of such customers to provide specific instructions with respect to their
shares of Sterling Common Stock to their broker will have the effect of a
negative vote. Each share of Sterling Common Stock is entitled to one vote on
each matter voted upon at the Special Meeting. The persons named as proxies by a
stockholder may propose and vote for one or more adjournments or postponements
of the Special Meeting to permit further solicitation of proxies in favor of
such proposal.
 
     A stockholder of record may revoke a proxy by filing an instrument of
revocation with John F. Treanor, Secretary of Sterling (One Moody Street,
Waltham, Massachusetts 02154), by filing a duly executed proxy bearing a later
date, or by appearing at the Special Meeting in person, notifying the Secretary,
and voting by
 
                                       19

<PAGE>   25
 
ballot at the Special Meeting. Any stockholder of record attending the Special
Meeting may vote in person whether or not a proxy has been previously given, but
the mere presence (without notifying the Secretary) of a stockholder at the
Special Meeting will not constitute revocation of a previously given proxy.
 
   
     If a stockholder is a participant in Sterling's Employee Stock Ownership
Plan and Trust (the "ESOP"), the proxy also will serve as voting instructions
for the trustee of the ESOP. Subject to the trustee's fiduciary obligations
under the Employee Retirement Income Security Act of 1974, the trustee will vote
the ESOP shares in accordance with the participants' voting instructions. If no
proxy is received from a participant in the ESOP, the shares in such
participant's account will not be voted by the trustee. Sterling anticipates
that the ESOP will be fully funded on or prior to March 31, 1994. See "THE
MERGER -- Effect on Employee Benefits".
    
 
VOTES REQUIRED
 
   
     The affirmative vote of the holders of a majority of the outstanding shares
of Sterling Common Stock is necessary to approve and adopt the Merger Agreement
and the transactions contemplated thereby. At December 31, 1993, directors and
executive officers of Sterling and their respective affiliates thereof held
approximately 318,582 shares, or approximately 10.46%, of the outstanding
Sterling Common Stock. Consequently, assuming, for illustration purposes only,
that the number of outstanding shares of Sterling Common Stock and the number of
such shares held by directors and officers of Sterling and their respective
affiliates remains unchanged between December 31, 1993 and the Record Date, and
that each director and executive officer of Sterling and their respective
affiliates vote in favor of the Merger Agreement, the affirmative vote of
holders of an additional 1,203,934 shares of Sterling Common Stock, representing
approximately 39.54% of the shares issued and outstanding, will be required to
approve and adopt the Merger Agreement. Each of the directors and executive
officers of Sterling has indicated his or her intention to vote the Sterling
Common Stock beneficially owned by him or her for approval of the Merger
Agreement. The approval of the Merger Agreement by Sterling's stockholders is a
condition to the consummation of the Merger.
    
 
                                   THE MERGER
 
GENERAL
 
     This section of the Proxy Statement-Prospectus describes certain aspects of
the proposed Merger, including the principal provisions of the Merger Agreement.
A copy of the Merger Agreement is attached to this Proxy Statement-Prospectus as
Exhibit A. All stockholders of Sterling are urged to read the Merger Agreement
in its entirety.
 
   
     The Merger Agreement has been unanimously approved by the Board of
Directors of Sterling. The Board of Directors of Sterling believes that the
terms of the Merger Agreement are fair and in the best interest of Sterling and
its stockholders and recommends that the stockholders vote to approve and adopt
the Merger Agreement.
    
 
BACKGROUND OF THE MERGER
 
     In September 1993, Sterling, through a member of its Board of Directors,
received an informal indication of interest from a financial institution
regarding a possible acquisition of Sterling. Sterling advised its financial
advisor, KBW, of the indication of interest. On September 14, 1993, the Board of
Directors met to discuss the indication of interest. At that meeting, management
and KBW advised the Board regarding the market for mergers and acquisitions in
the New England bank market, including recent acquisition activity. Management
and KBW advised the Board regarding Sterling's potential strategic options,
including continued internal growth, acquisitions by Sterling of smaller
financial institutions, a "merger-of-equals" transaction with an institution of
comparable size, and the acquisition of Sterling by a larger institution. In
this connection, KBW presented information which it had compiled with the
assistance of Sterling's management, illustrating the relative extent to which
stockholder value might be enhanced through these various options. KBW advised
that the market conditions for acquisitions by larger institutions had improved
to an extent that made
 
                                       20

<PAGE>   26
 
exploration of that option the most likely means of further enhancing
stockholder value at the present time. KBW advised that if the Board of
Directors of Sterling wished to explore this possibility further, it would be
appropriate for Sterling to conduct a controlled, confidential survey of
possible interest on the part of such institutions, in addition to the informal
indication of interest which had already been received. The Board of Directors
of Sterling authorized the President and Chief Financial Officer to explore
possible means of further enhancing stockholder values, including having
discussions with possible acquirors, and to engage KBW to act as Sterling's
financial advisor with respect to such possible transactions.
 
     Following the September 14, 1993 meeting of Sterling's Board of Directors,
another institution contacted Sterling with a preliminary indication of
interest. In addition, KBW contacted other financial institutions, including
Fleet, regarding their possible interest in acquiring Sterling. These contacts,
as well as the initial contact described above, resulted in meetings between
representatives of Sterling and representatives of four prospective acquirors.
Two institutions, including Fleet, proceeded to enter into confidentiality
agreements with Sterling and conducted due diligence reviews of the business
operations and legal affairs of Sterling and the Bank. The other institutions
which had contacted Sterling or had been contacted on Sterling's behalf
indicated that they did not wish to pursue a transaction or were unable to do so
in the near term due to other commitments.
 
     On October 1, 1993, KBW advised Fleet and the other financial institution
which had conducted due diligence that formal bids should be submitted to KBW no
later than Friday, October 8, 1993, at 1:00 p.m. The bidders were also requested
to provide all of their comments on a form of merger agreement which had been
proposed by Sterling's legal counsel, Goodwin, Procter & Hoar. On October 7,
1993, KBW was advised by the other financial institution which had conducted due
diligence that it did not intend to submit a bid. The institution indicated that
it was in the midst of pursuing another transaction.
 
     On October 8, 1993, Sterling received Fleet's bid, which stated, among
other things, that Fleet was offering to acquire all of the outstanding common
stock of Sterling for Fleet Common Stock, based on a per share value of Sterling
Common Stock of $39.00, and subject to a floating exchange ratio with a 15%
collar and certain "walkaway" provisions on the part of Sterling (based on a
decline in Fleet's stock price below certain thresholds) and Fleet (based on a
specified increase in Fleet's stock price above a certain threshold). Fleet's
offer stated that it was subject to execution of a definitive agreement (a copy
of which, as revised by Fleet, had been delivered to Sterling's counsel for
review earlier that week) and was not subject to any further due diligence.
 
     At an evening meeting of the Board of Directors of Sterling on October 8,
1993, KBW presented the Board with detailed financial and valuation analysis of
the offer which had been received from Fleet. KBW also presented its detailed
financial analysis of Sterling remaining independent compared to Fleet's offer,
the financial performance and market performance of Fleet, the potential
earnings per share and book value per share dilution involved in Fleet's offer,
Fleet's offer compared to recent comparable transactions, and the financial
history and prospects of Fleet. Also at the meeting, Goodwin, Procter & Hoar,
legal counsel to Sterling, reviewed the terms of the proposed agreement with
Fleet, including the grant of rights contemplated by the stock option agreement
required by Fleet as a condition to entering into the Merger Agreement. The
Board of Directors of Sterling authorized management, with the assistance of
Goodwin, Procter & Hoar and KBW, to negotiate definitive agreements with Fleet.
As a result of these negotiations, Fleet agreed, among other things, to
eliminate the provision allowing Fleet to terminate the transaction in the event
that its stock price increased over a certain level. In addition, as a result of
further clarification of the number of shares of Sterling Common Stock
outstanding and subject to issuance under outstanding options, Fleet agreed to
adjust the per share value of its offer to $39.50.
 
     At a meeting on October 10, 1993, the Board of Directors reviewed the terms
of the proposed Merger Agreement and Stock Option Agreement. Management and
Goodwin, Procter & Hoar reviewed with the Board of Directors the course of the
negotiations with Fleet and its representatives. The Board of Directors also
discussed the stockholder and regulatory approvals that would be required to
consummate the Merger. At this meeting, KBW reviewed for the Board its financial
and valuation analysis of the Fleet proposal. In addition, KBW delivered to the
Board of Directors its oral opinion to the effect that, as of such date, the
 
                                       21
<PAGE>   27
 
Exchange Ratio to be received by the holders of Sterling Common Stock pursuant
to the Merger Agreement would be fair, from a financial point of view, to
Sterling's stockholders. Management of Sterling and representatives of Goodwin,
Procter & Hoar and KBW reviewed various provisions of the proposed Merger
Agreement and the Stock Option Agreement and responded to questions from
Directors. At the conclusion of this meeting, the Board of Directors unanimously
approved entering into the Merger Agreement and Stock Option Agreement with
Fleet. The Merger Agreement and Stock Option Agreement were entered into on
October 11, 1993.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS AND REASONS FOR THE MERGER
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR
THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
     In the course of reaching its decision to approve the Merger Agreement, the
Board of Directors of Sterling consulted with its legal advisors regarding the
legal terms of the Merger Agreement and Stock Option Agreement and the Board of
Directors' obligations in its consideration thereof, its financial advisors
regarding the financial terms and fairness, from a financial point of view, of
the Exchange Ratio in the proposed Merger, and the management of Sterling.
Without assigning any relative or specific weights thereto, the Board of
Directors considered the factors outlined below, among others, that it believed
relevant to reaching its determination.
 
   
     The terms of the Merger Agreement, including the Exchange Ratio and the
Stock Option Agreement, were reached on the basis of arms' length negotiations
between Sterling and Fleet. In reaching the conclusion that the terms of the
Merger Agreement are fair, the Board of Directors considered, among other
things, the market value, book value, and earnings per share of Sterling Common
Stock. It is the business judgment of the Board of Directors that the Merger
provides an opportunity for the stockholders of Sterling to receive
consideration for their shares having a value in excess of the book value of the
Sterling Common Stock, and that the Exchange Ratio represents a substantial
premium over the prices at which the Sterling Common Stock has traded in the
recent past (and the range of prospects for the future in the absence of the
Merger). At September 30, 1993, the book value per share of the Sterling Common
Stock was $21.37. On October 8, 1993, the last trading day preceding the public
announcement of the proposed Merger, the high and low per share sales prices for
Sterling Common Stock reported on the NASDAQ National Market were $31.75 and
$27.00, respectively. Since January 1, 1993, Sterling Common Stock had traded as
low as $17.50 per share. See "COMPARATIVE STOCK PRICES AND DIVIDENDS".
    
 
     In reaching its conclusion, the Board of Directors took into consideration
and relied upon the opinion of KBW, Sterling's financial advisor. At the October
10, 1993 meeting of Sterling's Board of Directors, KBW made a presentation
regarding the financial aspects of the Merger and rendered its oral opinion to
the effect that, as of such date, the Exchange Ratio was fair to such
stockholders from a financial point of view. That opinion was rendered again in
writing as of the date of this Proxy Statement-Prospectus. A copy of the written
opinion, dated the date of this Proxy Statement-Prospectus, rendered by KBW to
the Board of Directors is attached as Exhibit C to this Proxy
Statement-Prospectus. Sterling's Board of Directors considered the analyses
presented to it by KBW, relating to selected financial and stock market data
concerning Sterling and Fleet and other publicly held bank holding companies,
certain financial analyses of the terms of the Merger, including a discounted
cash flow analysis and a comparison to the terms of other recent business
combinations involving bank holding companies which are described below under
"THE MERGER -- Opinion of Financial Advisor."
 
     The Board of Directors considered the strategic alternatives available to
Sterling, including the possibility of remaining independent (and continuing
with no acquisitions, acquisitions of smaller institutions, or a
"merger-of-equals"), seeking further to solicit competing proposals, and
accepting Fleet's bid, before concluding for the reasons discussed in this
Section that the Merger represented the best available alternative to enhance
stockholder value at this time and that the Exchange Ratio was fair to the
stockholders.
 
     In assessing the alternatives for remaining independent, the Board of
Directors considered the long-range business prospects and risks of Sterling's
business, financial condition and results of operations. In this regard,
 
                                       22
<PAGE>   28
 
the Board of Directors considered that although Sterling's financial condition
and results of operations had improved significantly during the past two years
and management believed that continued improvement was possible, comparable
future growth could not be assured. In assessing the long-range prospects and
risks of Sterling's business, the Board of Directors considered the risks posed
by the continuing uncertainty of economic recovery in New England and the risk
that the recent favorable interest rate environment might not continue, as well
as the fact that the banking markets in which Sterling operates are becoming
increasingly concentrated and competitive.
 
     In considering the competitive pressures in the financial services industry
in general and the banking industry in particular, the Board of Directors of
Sterling recognized that the banking industry is in the midst of a major
transformation and restructuring. In particular, the Board of Directors believes
that the banking industry is experiencing significant pressure for consolidation
as a result of many factors, including industry overcapacity, increased
competition from non-bank financial services competitors, technological change
and the evolving legislative environment. Sterling's Board of Directors believes
that the proposed business combination with Fleet could lead to competitive
advantages through greater diversity in product offerings, cost-savings through
integration of operations, improved access to capital and funding, and
geographic expansion of operations. Sterling's Board considered the fact that,
although the Bank had succeeded in expanding through the acquisition of two
failed institutions in 1991, it had not been able to effect additional
acquisitions of smaller financial institutions since that time on terms which it
considered reasonable.
 
     The Board of Directors considered the process that was used to solicit
indications of interest on the part of potential acquirors of Sterling. In
deciding to accept the offer submitted by Fleet, after soliciting indications of
interest on a controlled and confidential basis but without conducting a formal
auction of Sterling, the Board considered the fact that each of the large
institutions with a significant market presence in Eastern Massachusetts had
been approached for (or had approached Sterling with) an indication of possible
interest, and that KBW had also approached certain banks not currently in the
market served by Sterling which were viewed by KBW as potential acquirors with
respect to their possible interest. The Board also considered the fact that it
was KBW's advice that these institutions represented all of the most likely
prospective bidders for Sterling and the fact that none of the institutions,
other than Fleet, had engaged in negotiations with Sterling or submitted an
offer to acquire Sterling. The Board also considered the risk that Fleet might
withdraw its offer if Sterling were to extend the period of time during which it
would entertain other offers, and the disruption and potential harm to Sterling
that could result from engaging in a formal auction process.
 
   
     The Board of Directors considered the historical growth in Fleet's earnings
per share and book value. The Board of Directors also considered the historical
dividends paid on the Sterling Common Stock and Fleet Common Stock,
respectively, and the significant increase in dividends which would be likely to
result to Sterling stockholders from the Merger. The Board of Directors also
considered the expectation that the Merger will be a tax-free transaction to
Sterling stockholders, Sterling and Fleet and accounted for under the "pooling
of interests" method of accounting.
    
 
   
     The Board of Directors considered the conditions to the Merger and the
risks to Sterling if the Merger was not consummated. The Board of Directors was
advised that the conditions to the Merger included, among other things (a) that
the representations and warranties contained in the Merger Agreement shall be
true and correct in all material respects as of the date of the Merger Agreement
and as of the closing date of the Merger and (b) that all regulatory approvals
required to consummate the Merger shall have been obtained and shall remain in
full force and effect and all statutory waiting periods in respect thereof shall
have expired. The Board of Directors also considered the risks to Sterling of
non-consummation of the transaction, including that the termination of the
Merger Agreement might result in a decline in the market price of Sterling
Common Stock and might have other adverse operational consequences for Sterling
and its subsidiaries.
    
 
     The Board of Directors considered the fact that approval of the Merger
Agreement requires the affirmative vote of a majority of the shares of Sterling
Common Stock outstanding and entitled to vote, consisting primarily of persons
other than the members of management, and that the Board of Directors' decision
to approve the Merger Agreement would empower the stockholders as a group to
decide whether or not to accept Fleet's proposal to acquire Sterling.
 
                                       23
<PAGE>   29
 
     The Board of Directors considered the possible impact of the Merger on
Sterling's and the Bank's employees, customers and community. Sterling's
Restated Certificate of Incorporation permits the Board of Directors to consider
a variety of factors, including, without limitation, the economic effects of a
transaction on depositors, borrowers and employees of Sterling and its
subsidiaries, and on the communities served by Sterling and its subsidiaries.
Delaware law permits the Board of Directors to consider these factors, at least
to the extent that there are rationally related benefits accruing to
stockholders. The Board of Directors believes that the Merger, if consummated,
will provide expanded services, greater ability to grow and diversify, and
access to the resources of a strong financial parent. Additionally, the Board of
Directors believes that, while the Merger is likely to result in the termination
of a significant number of employees of Sterling and the Bank, certain employees
of the Bank may experience expanded job opportunities within the Fleet
organization after consummation of the Merger. The Board also considered the
fact that terminated employees will receive severance benefits provided for in
the Merger Agreement. See "THE MERGER -- Effect on Employee Benefits".
 
     In reviewing the terms of the Stock Option Agreement, the Board of
Directors was aware that the existence of the Stock Option Agreement would make
it more expensive for a third party to offer a price that was in excess of
Fleet's proposal. The Board of Directors was aware that the Stock Option
Agreement might significantly deter a potential competing acquiror from making
an offer. The Board of Directors was also aware that Fleet required the Stock
Option Agreement as a condition to entering into the Merger Agreement. See "THE
MERGER -- Stock Option Agreement". If the Sterling stockholders do not approve
and adopt the Merger Agreement or the Merger is not consummated for any other
reason, the Board of Directors expects to continue to operate Sterling as an
ongoing business.
 
OPINION OF FINANCIAL ADVISOR
 
     KBW has delivered to Sterling's Board of Directors its oral opinion, as of
October 10, 1993, and its written opinion, as of the date of this Proxy
Statement-Prospectus, that the Exchange Ratio is fair, from a financial point of
view, to Sterling's stockholders. No limitations were imposed by the Board of
Directors upon KBW with respect to the investigations made or procedures
followed by KBW in rendering its opinions.
 
     THE FULL TEXT OF THE OPINION OF KBW DATED AS OF THE DATE OF THIS PROXY
STATEMENT-PROSPECTUS, WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITS ON THE REVIEW UNDERTAKEN BY KBW, IS ATTACHED HERETO AS EXHIBIT C.
STOCKHOLDERS ARE URGED TO READ THIS OPINION IN ITS ENTIRETY. KBW'S OPINION IS
DIRECTED ONLY TO THE EXCHANGE RATIO AND DOES NOT CONSTITUTE A RECOMMENDATION TO
ANY STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE SPECIAL MEETING.
THE SUMMARY OF THE OPINION OF KBW SET FORTH IN THIS PROXY STATEMENT-PROSPECTUS
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
     In connection with its opinions, KBW reviewed, among other things: (a) the
Merger Agreement; (b) certain publicly available reports filed with the
Commission by Sterling and Fleet; (c) certain other publicly available financial
and other information concerning Sterling and Fleet and the trading markets for
the publicly traded securities of Sterling and Fleet; (d) certain other internal
information, including projections, relating to Sterling, prepared by the
management of Sterling and furnished to KBW for purposes of its analysis; and
(e) publicly available information concerning certain other depository
institutions and bank holding companies, the trading markets for their
securities and the nature and terms of certain other merger and acquisition
transactions KBW believed relevant to its inquiry. In addition, in connection
with its written opinion dated the date hereof, KBW reviewed this Proxy
Statement-Prospectus in substantially the form to be sent to Sterling's
stockholders. KBW also met with certain officers and representatives of Sterling
and Fleet to discuss the foregoing as well as other matters KBW believed
relevant to its inquiry. KBW also considered such financial and other factors as
it deemed appropriate under the circumstances and took into account its
assessment of general economic, market and financial conditions and its
experience in similar transactions, as well as its experience in securities
valuation and its knowledge of depository institutions and holding companies
generally. No limitations were imposed by the Board of Directors of Sterling
upon KBW with
 
                                       24
<PAGE>   30
 
   
respect to the investigations made or procedures followed by KBW in rendering
its opinions. KBW's opinions were necessarily based upon conditions as they
existed and could be evaluated on the date thereof and the information made
available to KBW through the date thereof.
    
 
   
     In conducting its review and in arriving at its opinions, KBW relied upon
and assumed the accuracy and completeness of the financial and other information
provided to it or publicly available and did not attempt independently to verify
the same. KBW relied upon the management of Sterling as to the reasonableness
and achievability of the projections (and the assumptions and bases therefor)
provided to KBW, and assumed that such projections reflected the best currently
available estimates and judgments of such management and that such projections
would be realized in the amounts and in the time periods estimated by such
management. KBW also assumed, without independent verification, that the
aggregate allowance for loan losses for Sterling was adequate to cover such
losses. KBW did not make or obtain any evaluations or appraisals of the property
of Sterling, nor did KBW examine any individual loan credit files. KBW was
informed by Fleet and assumed for purposes of its opinion that the Merger will
be recorded as a pooling-of-interests under generally accepted accounting
principles. KBW was retained by Sterling's Board of Directors to express an
opinion as to the fairness, from a financial point of view, to Sterling's
stockholders of the financial consideration to be received in the Merger. KBW
did not address Sterling's underlying business decision to proceed with the
Merger and did not make any recommendation to the Board of Directors or to the
stockholders of Sterling with respect to any approval of the Merger.
    
 
     In connection with rendering its opinions to the Board of Directors, KBW
performed a variety of financial analyses which are summarized below. KBW
believes that its analyses must be considered as a whole and that selecting
portions of such analyses and the factors considered therein, without
considering all factors and analyses, could create an incomplete view of the
analyses and the processes underlying KBW's opinions. The preparation of a
fairness opinion is a complex process involving subjective judgments and is not
necessarily susceptible to partial analyses or summary description. In its
analyses, KBW made numerous assumptions with respect to industry performance,
business and economic conditions and other matters, many of which are beyond
Sterling's control. Any estimates contained in KBW's analyses are not
necessarily indicative of future results or values, which may be significantly
more or less favorable than such estimates. Estimates of values of companies do
not purport to be appraisals or necessarily reflect the prices at which
companies or their securities actually may be sold. None of the analyses
performed by KBW was assigned a greater significance by KBW than any other.
 
     The projections reviewed by KBW were prepared by the management of
Sterling. Sterling does not publicly disclose internal management projections of
the type provided to its Board of Directors and to KBW in connection with the
review of the Merger. Such projections were not prepared with a view towards
public disclosure. The projections were based on numerous variables and
assumptions which are inherently uncertain, including without limitation,
factors related to general economic and competitive conditions. Accordingly,
actual results could vary significantly from those set forth in such
projections.
 
     Set forth below is a brief summary of all material analyses presented by
KBW to Sterling's Board of Directors on October 8, 1993 and further reviewed
with the Board of Directors on October 10, 1993, and which were used by KBW in
connection with its oral opinion as to the fairness of the Exchange Ratio from a
financial point of view, to Sterling's stockholders.
 
   
     Summary of Fleet Bid.  KBW reviewed the terms of the Fleet merger offer
which had been submitted to the Sterling Board of Directors, including the
Exchange Ratio, the aggregate transaction value, the value per share of Sterling
Common Stock and the effect of a change in the price of Fleet Common Stock. KBW
also discussed certain conditions and price protection provisions contained in
the Fleet bid.
    
 
     KBW noted that, based on the then-current stock prices, the multiples to
KBW's published estimate of Sterling's 1993 and 1994 earnings were 14.9 and
13.8, respectively, and the multiple to Sterling's June 30, 1993 book value of
Fleet's offer was approximately 1.87. KBW also noted that, based on the average
closing price of Sterling Common Stock on the ten trading days preceding the
October 8, 1993 Sterling Board of Directors meeting, the Fleet offer represented
a 55% premium over Sterling's prevailing stock price.

     Merger Partner Peer Group Analysis.  KBW compared the financial performance
of Fleet based on various financial measures of earnings performance, capital
adequacy, asset quality and dividend yield to that of a peer group of regional
and super regional banking holding companies, including Bank of Boston, Shawmut
National Corporation, First Fidelity Bancorporation and Citizens Financial
Group, Inc. (which were considered by KBW to be actively or potentially "in the
market" to acquire banks of Sterling's size in Sterling's market area), and Banc
One Corp., Key Corp, BayBanks, Inc. and CoreStates Financial Corp. (which KBW
viewed as not likely to be "in the market" for such an acquisition). This
analysis showed, among other things, that as of June 30, 1993 and for the first
six months of 1993, Fleet's return on assets was 0.93% compared to a peer group
average of 1.03% (or 0.85% for the "in-the-market" peer group), its return on
equity was 14.14% compared to a peer group average of 14.57% (or 13.18% for the
"in-the-market" peer group), its net interest margin was 5.07% compared to a
peer group average of 4.89% (or 4.20% for the "in-the-market" peer group), its
expense ratio was 2.30% compared to a peer group average of 2.75% (or 2.65% for
the "in-the-market" peer group), its efficiency ratio was 64.89% compared to a
peer group average of 65.46% (or 65.98% for the "in-the-market" peer group), its
equity to assets ratio was 7.67% compared to a peer group average of 7.37% (or
7.15% for the "in-the-market" peer group), its ratio of nonperforming assets to
total loans and OREO was 3.24% compared to a peer group average of 2.82% (or
3.06% for the "in-the-market" peer group), and its net charge-offs to average
loans ratio was 1.10% compared to a peer group average of 1.25% (or 1.50% for
the "in-the-market" peer group). In addition, Fleet's estimated price to
earnings multiple based on 1994 estimated earnings was 10.07 compared to a peer
group average of 9.99 (or 9.27 for the "in-the-market" peer group), its price to
June 30, 1993 book value multiple was 1.59 compared to a peer group average of
1.59 (or 1.43 for the "in-the-market" peer group), and its dividend yield was
2.92% compared to a peer group average of 2.32% (or 1.62% for the
"in-the-market" peer group). For purposes of the above calculations, all
earnings estimates are based upon the published estimates of KBW's equity
research department. The peer group averages exclude Fleet.
    
 
   
     Analysis of Selected Merger Transactions.  KBW reviewed certain financial
data relating to bank merger transactions in a similar size range or geographic
location. The bank mergers include (acquiror/acquiree): Bank of Boston
Corporation/BankWorcester, Shawmut National Corporation/Peoples Bancorp of
Worcester, Inc., PNC Financial Corp./United Federal Bancorp, Inc., First
Fidelity Bancorporation/Peoples Westchester Savings Bank, Citizens Financial
Group, Inc./The Boston Five Bancorp, Inc., Shawmut National
Corporation/Dartmouth Bancorp, Inc., ONBANCorp. Inc./Franklin First Financial
Corp., Bank of Boston Corporation/Society for Savings Bancorp, and
KeyCorp/National Savings Bank of Albany. KBW calculated the price multiples to
the target's estimated or trailing earnings and book value, tangible book value
and recent market price.
    
 
     In the selected transactions, the calculations yielded, as of the date of
announcement of each transaction, (i) an average price to earnings multiple of
18.8 (compared to a multiple of 14.9 associated with the Exchange Ratio), (ii)
an average price to book value multiple of 1.45 (compared to a multiple of 1.87
associated with the Exchange Ratio), and (iii) an average price to market value
multiple of 1.47 (compared to a multiple of 1.55 associated with the Exchange
Ratio based on the average closing price of Sterling Common Stock on the ten
trading days preceding the October 8, 1993 Board of Directors meeting).
 
   
     Sterling Peer Group Analysis.  KBW compared the financial performance of
Sterling based on various financial measurements of earnings performance,
capital adequacy, and asset quality to that of a peer group of institutions of
comparable size in Eastern Massachusetts, including Andover Bancorp, Inc.,
Bankworcester Corporation, The Co-Operative Bank of Concord, First Essex
Bancorp, Inc., Massbank Corp., Regional Bancorp, Inc., Neworld Bancorp, Inc.,
and NBB Bancorp, Inc. With respect to earnings performance, this analysis
showed, among other things, that for the second quarter of 1993 (annualized)
Sterling's return on assets was 0.84% compared to a peer group average of 0.85%,
its return on equity was 13.05% compared to a peer group average of 9.85%, its
net interest margin was 3.91% compared to a peer group average of 3.87%, its
expense ratio was 2.01% compared to a peer group average of 2.32%, and its
efficiency ratio was 53.53% compared to a peer group average of 64.19%. With
respect to capital adequacy, Sterling's equity to assets ratio was 6.49%
compared to a peer group average of 8.64%, and its "tier one" capital ratio was
12.5% compared to a peer group average of 13.95%. With respect to asset quality,
this analysis showed that Sterling's ratio of
    
 
                                       26
<PAGE>   32
 
nonperforming assets to total loans and OREO was 1.7% compared to a peer group
average of 4.0%, its ratio of loan loss reserves to nonperforming loans was 156%
compared to a peer group average of 136%, and its ratio of nonperforming assets
to equity and loan loss reserves was 10.4% compared to a peer group average of
24.4%. (The peer group averages exclude Sterling.)
 
     No company or transaction used in the above analyses as a comparison is
identical to Sterling, Fleet or the contemplated transaction. Accordingly, an
analysis of the results of the foregoing is not mathematical; rather, it
involves complex considerations and judgments concerning differences in
financial and operating characteristics of the companies and other factors that
could affect the public trading value of the companies to which they are being
compared.
 
   
     Stand Alone Versus Upstream Affiliation Analysis.  KBW performed an
analysis comparing assumed earnings, dividends and price/earnings ratio values
for Sterling on a stand alone basis and for Sterling after affiliating with a
larger bank holding company. For the stand alone analysis, KBW assumed an
earnings growth rate and a dividend payout ratio approximating an industry
average and increased the dividend over time. In addition, KBW applied a
price/earnings ratio similar to Sterling's price/earnings ratio prior to the
acquisition announcement to the earnings estimate.
    
 
     KBW also performed the same analysis assuming Sterling affiliated with
Fleet using the exchange ratio offered in Fleet's bid. KBW assumed certain
earnings and dividends growth on the part of Fleet. KBW applied the approximate
price/earnings multiples that the respective companies were selling for at
October 8, 1993 to the earnings estimates. The foregoing analyses were based
upon varying assumptions concerning earnings growth rates and market conditions,
which assumptions are themselves based upon many factors and assumptions, many
of which are beyond the control of Sterling and Fleet. The foregoing analyses
were not necessarily indicative of actual values or actual future results and do
not purport to reflect the prices at which any securities may trade at the
present time or at any time in the future.
 
   
     Contribution Analysis.  KBW analyzed the relative contribution of each of
Sterling and Fleet to certain balance sheet and income statement items,
including assets, common equity, and 1994 estimated earnings. KBW then compared
the ownership percentages of the combined company implied by the relative
contributions of such balance sheet and income statement items, with
approximately 2.0% ownership percentage for Sterling stockholders resulting from
an assumed Exchange Ratio of 1.1575 (based on the $34.125 closing price per
share of Fleet Common Stock on October 8, 1993) contained in the Fleet proposal.
The contribution analysis showed that under the proposal, Sterling would
contribute approximately 2.0% of the combined assets, 2.0% of the combined
common equity and 2.0% of the estimated 1994 earnings of the two companies
(before cost savings).
    
 
   
     Merger Impact Analysis.  KBW analyzed certain pro forma effects resulting
from the Merger based upon 1994 earnings estimates of KBW's equity research
department. This analysis, based on the assumptions described above, showed that
the Merger should result in little, if any, dilution of Fleet earnings after
giving effect to projected cost savings.
    
 
   
     Discounted Cash Flow Analysis.  KBW estimated the present value of the
future streams of after-tax cash flows that Sterling could produce through 1996.
The analysis was based on several assumptions, including a $0.86 dividend per
share in 1994, a $1.09 dividend per share in 1995 (a 35% payout ratio), a $1.36
dividend per share in 1996 (a 40% payout ratio), earnings per share of $3.40 in
1996 and a book value per share of $27.61 in 1996. A terminal value was
calculated for 1996 by multiplying Sterling's projected 1996 earnings by a price
to earnings multiple of 12 times and a price to book value multiple of 1.75
times, chosen to reflect possible acquisition premiums. The terminal values were
then discounted to present value using an 18% discount rate chosen to reflect an
assumed required rate of return of prospective buyers of Sterling Common Stock.
This discounted terminal valuation analysis indicated a reference range of
between $28.00 and $31.80 per share of Sterling Common Stock. KBW also provided
a sensitivity analysis showing the range of discounted values that would result
if discount rates ranging from 15% to 18% were utilized and a terminal
price-to-earnings multiple of 10 to 14 times, and terminal book value multiples
of 1.55 to 1.95 times, were applied. This analysis showed a range of values
based upon the terminal price-to-earnings multiples of $23.70 to $34.80 and a
range of values based upon the terminal book value multiples of $28.40 to
$37.90. KBW

compared these values to a range of potential values provided to Sterling
stockholders in the Merger. This analysis was based upon varying assumptions
provided by Sterling management concerning required reserve levels, earnings
growth rates and exit multiples, which assumptions are themselves based on many
factors and assumptions, many of which are beyond the control of Sterling and
Fleet. This analysis also assumed that Sterling stockholders received Fleet's
stock at the proposed exchange ratio, held the stock and received the
appropriate Fleet dividend and sold Fleet stock into the open market at year end
1996. This analysis showed a range of discounted values for Sterling
stockholders of $32.00 to $41.00. As indicated above, this analysis is not
necessarily indicative of actual values or actual future results and does not
purport to reflect the prices at which any securities may trade at the present
time or at any time in the future.
 
     In connection with its written opinion dated the date of this Proxy
Statement-Prospectus, KBW also confirmed the appropriateness of its reliance on
the analyses used to render its October 10, 1993 oral opinion by performing
procedures to update certain of such analyses and by reviewing the assumptions
on which such analyses were based and the factors considered in connection
therewith.
 
     KBW is a recognized investment banking firm and, as part of its investment
banking business, is continually engaged in the valuation of bank and bank
holding company securities in connection with acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for various other purposes. As specialists in
the securities of banking companies, KBW has experience in, and knowledge of,
the valuation of banking enterprises. Sterling selected KBW as its financial
adviser because of its reputation and because of its substantial experience in
transactions such as the Merger.
 
     Sterling and KBW have entered into a letter agreement, dated as of
September 23, 1993 (the "KBW Engagement Letter"), relating to the services to be
provided by KBW in connection with the Merger. Pursuant to the KBW Engagement
Letter, Sterling has paid KBW fees of $500,000 through the date of mailing of
this Proxy Statement-Prospectus to stockholders, and has agreed to pay KBW at
the closing of the Merger an additional cash fee (the "Percentage Fee") equal to
0.8% of the market value of the aggregate consideration paid in the Merger, up
to $31.25 per share, and 2.0% of the market value of the aggregate consideration
paid in the Merger in excess of $31.25 per share. The fees paid prior to the
Percentage Fee will be credited against the Percentage Fee. In the KBW
Engagement Letter, Sterling also has agreed to reimburse KBW for its reasonable
and necessary out-of-pocket expenses and to indemnify KBW against certain
liabilities, including liabilities under the federal securities laws.
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
     Upon consummation of the Merger, the directors and officers of Fleet
immediately prior to the Effective Time shall remain the directors and officers
of the surviving corporation, each to hold office in accordance with the charter
document and bylaws of the surviving corporation until their respective
successors are duly elected or appointed and qualified.
 
EXCHANGE RATIO AND OTHER MATTERS
 
   
     In the Merger, each share of Sterling Common Stock outstanding (other than
shares (a) held by Sterling as treasury stock or (b) held by Fleet or Sterling
or any subsidiary thereof (other than in both cases shares 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 ("Trust
Account Shares") or as a result of debts previously contracted ("DPC Shares"))
will be converted into and exchangeable for the number of shares (the "Exchange
Ratio") of Fleet Common Stock determined by dividing $39.50 by the Average
Closing Price (as defined below); provided, that (i) if the Average Closing
Price is equal to or greater than $39.24, the Exchange Ratio shall be 1.0066
(the "Minimum Exchange Ratio") and (ii) if the Average Closing Price is equal to
or less than $29.01, the Exchange Ratio shall be 1.3616 (the "Maximum Exchange
Ratio"); and provided, further, that if the Average Closing Price is equal to or
less than $25.59, Sterling shall have the right, waivable by it, to terminate
the Merger Agreement, unless Fleet elects, at its option, to adopt as the
Exchange Ratio the "Adjusted Maximum Exchange Ratio" which shall be determined
by dividing $34.84 by the
    
 
                                       28
<PAGE>   34
 
Average Closing Price. The "Average Closing Price" is defined in the Merger
Agreement as the average closing sale price per share of Fleet Common Stock on
the Stock Exchange (as reported by The Wall Street Journal or, if not reported
thereby, another authoritative source), for the twenty (20) Stock Exchange
trading days ending on the tenth business day after the date on which the last
of the regulatory approvals required to consummate the transactions contemplated
by the Merger Agreement is obtained.
 
     The Merger Agreement provides that, in the event that Fleet changes the
number of shares of Fleet Common Stock issued and outstanding between October
11, 1993 and the Effective Time as a result of a stock split, combination,
dividend payment or other distribution in Fleet Common Stock, the Exchange Ratio
and, if applicable, the Minimum Exchange Ratio, the Maximum Exchange Ratio and
the Adjusted Maximum Exchange Ratio, will be adjusted proportionately.
 
   
     Each outstanding share of Sterling Common Stock owned by Fleet and its
subsidiaries or Sterling and its subsidiaries (other than Trust Account Shares
or DPC Shares) or by Sterling as treasury stock will be cancelled at the
Effective Time and shall cease to exist, and no Fleet Common Stock or other
consideration will be made with respect thereto. Each outstanding share of Fleet
Common Stock or Fleet preferred stock that is owned by Sterling (other than
Trust Account Shares and DPC Shares) shall become treasury stock of Fleet.
    
 
   
     In addition, at the Effective Time all stock options with respect to
Sterling Common Stock granted by Sterling under the Sterling Stock Option Plan,
which are outstanding and unexercised immediately prior thereto, whether or not
then exercisable, will be converted into and will become stock options under the
Fleet Stock Option Plan to purchase Fleet Common Stock. The rights to Fleet
Common Stock to be received by holders of Sterling stock options upon
consummation of the Merger will be the same as the rights such optionees had
under the Sterling Stock Option Plan immediately prior to the Effective Time,
except that (a) the number of shares of Fleet Common Stock subject to the new
option shall be equal to the product of the number of shares of Sterling Common
Stock subject to the original option and the Exchange Ratio and (b) the exercise
price per share of Fleet Common Stock subject to the new option shall be equal
to the exercise price per share of Sterling Common Stock under the original
option divided by the Exchange Ratio. The duration and other terms of each new
option shall be the same as the original option except that all references in
such option to Sterling shall be deemed to be references to Fleet. The shares of
Fleet Common Stock issuable upon exercise of such options are registered on a
Form S-8 filed with the Commission on June 23, 1992.
    
 
   
     Shares of Fleet capital stock (including Fleet Common Stock) issued and
outstanding immediately prior to the Effective Time will remain issued and
outstanding immediately after the Merger.
    
 
EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES
 
     The conversion of Sterling Common Stock into Fleet Common Stock will occur
automatically at the Effective Time of the Merger. As soon as practicable after
the Effective Time, and in no event later than three business days thereafter,
transmittal forms will be furnished to Sterling stockholders by Fleet National
Bank (the "Exchange Agent"). The transmittal forms will contain instructions
with respect to the surrender of certificates representing Sterling Common Stock
to be exchanged for certificates representing Fleet Common Stock.
 
     STERLING STOCK CERTIFICATES SHOULD NOT BE FORWARDED TO THE EXCHANGE AGENT
UNTIL A STERLING STOCKHOLDER HAS RECEIVED A TRANSMITTAL FORM AND SHOULD NOT BE
RETURNED WITH THE ENCLOSED PROXY.
 
   
     Until the certificates representing Sterling Common Stock are surrendered
for exchange after the Effective Time of the Merger, holders of such
certificates will accrue but will not be paid dividends or other distributions
on the Fleet Common Stock into which their shares have been converted. When such
certificates are surrendered, any unpaid dividends or other distributions will
be paid, without interest. No interest will be paid or accrued on the cash in
lieu of fractional shares payable to holders of such certificates. For all other
purposes, however, each certificate which represents outstanding shares of
Sterling Common Stock outstand-
    
 
                                       29
<PAGE>   35
 
ing at the Effective Time of the Merger will be deemed to evidence ownership of
the shares of Fleet Common Stock into which those shares have been converted
pursuant to the Merger.
 
     No fractional shares of Fleet Common Stock will be issued to any Sterling
stockholder upon consummation of the Merger. For each fractional share that
would otherwise be issued, Fleet will pay cash in an amount equal to such
fraction multiplied by the closing sale price of Fleet Common Stock on the Stock
Exchange as reported by The Wall Street Journal for the Stock Exchange trading
day immediately preceding the date of the Effective Time. Calculations will be
made to the nearest one-thousandth of a share of Fleet Common Stock and to the
nearest cent.
 
     Fleet will pay all stock transfer taxes, if any, owing in connection with
the exchange of shares of Sterling Common Stock for shares of Fleet Common Stock
and/or cash in lieu of fractional shares. Fleet will not pay any stock transfer
taxes resulting from such issuances and/or payment to any person other than a
registered holder.
 
     For a description of the differences between the rights of the holders of
Sterling Common Stock and Fleet Common Stock, see "COMPARISON OF STOCKHOLDERS'
RIGHTS UNDER RHODE ISLAND AND DELAWARE LAW". For a description of the capital
stock of Fleet, see "DESCRIPTION OF FLEET CAPITAL STOCK".
 
EFFECTIVE TIME
 
   
     The Effective Time will be as set forth in the Articles of Merger (the
"Articles of Merger") which shall be filed with the Secretary of State of the
State of Rhode Island and the Certificate of Merger (the "Certificate of
Merger") which shall be filed with the Secretary of State of the State of
Delaware, each on the Closing Date. The Closing Date will occur not more than
five business days following the satisfaction of the conditions set forth in
Section 7.01 of the Merger Agreement which include, among other things,
stockholder approval of the Merger and the receipt of regulatory approvals
required to consummate the Merger (including expiration of all applicable
waiting periods in respect thereof), except that Fleet may delay the Closing
Date until the earlier of (i) August 24, 1994 or (ii) a day selected by Fleet
that is not more than 5 business days after receipt of all regulatory approvals
(and the expiration of all applicable waiting periods) required to consummate
the Merger and the Bank Merger if it delivers to Sterling a written notice
irrevocable waiving all conditions to its obligations to effect the Merger.
Sterling and Fleet each anticipate that the Merger will be consummated during
the second quarter of 1994. However, the consummation of the Merger could be
delayed as a result of delays in obtaining the necessary governmental and
regulatory approvals. There can be no assurances given that such approvals will
be obtained or that the Merger will be completed at any time. See "THE
MERGER -- Conditions to the Consummation of the Merger" and "-- Regulatory
Matters".
    
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
   
     Pursuant to the Merger Agreement, prior to the Effective Time, Sterling and
Fleet have each agreed to carry on their respective businesses and those of
their respective subsidiaries in the ordinary course consistent with past
practices, except, in the case of Sterling, as is contemplated by the Merger
Agreement or with the prior written consent of Fleet. Sterling and Fleet have
also agreed, subject to the terms and conditions of the Merger Agreement, to use
all best efforts to consummate the Merger.
    
 
     Sterling has agreed to give Fleet access to all of its properties, books,
contracts, commitments and records and to furnish information concerning its
businesses, properties and personnel.
 
     Fleet has agreed to give Sterling access to such information regarding
Fleet and its subsidiaries as shall be reasonably necessary for Sterling to
prepare this Proxy Statement-Prospectus, and for Sterling to verify that Fleet's
representations and warranties under the Merger Agreement are true and correct
and that Fleet's covenants contained therein have been performed in all material
respects.
 
                                       30

     In addition, except as contemplated by the Merger Agreement, Sterling has
agreed that, without the consent of Fleet, it will not, among other things:
 
          (a) declare or pay any dividends on, or make other distributions in
     respect of, any of its capital stock, except (i) for the declaration and
     payment of regular quarterly cash dividends in an amount not to exceed the
     amount of the most recent quarterly cash dividend paid by Sterling prior to
     October 11, 1993; provided, however, that Sterling's regular quarterly cash
     dividend may be increased by up to $.04 per share of Sterling Common Stock
     beginning in the second quarter of 1994, and (ii) that Sterling and Fleet
     have agreed (x) to consult with respect to the amount of the last Sterling
     quarterly dividend payable prior to the Effective Time with the objective
     of assuring that the stockholders of Sterling do not receive a shortfall
     based on the record and payment dates of their last dividend prior to the
     Merger and the record and payment dates of the first dividend of Fleet
     following the Merger and (y) that Sterling may pay a special dividend to
     holders of record of Sterling Common Stock immediately prior to the
     Effective Time consistent with the objective described in clause (x) above;
 
   
          (b) (i) split, combine or reclassify any shares of its capital stock
     or issue or authorize or propose the issuance of any other securities in
     respect of, in lieu of or in substitution for shares of its capital stock
     except upon the exercise or fulfillment of rights or options issued or
     existing pursuant to employee benefit plans, programs or arrangements, all
     to the extent outstanding and in existence on October 11, 1993, or (ii)
     repurchase, redeem or otherwise acquire (except for the acquisition of
     shares pursuant to the ESOP, Sterling's Dividend Reinvestment and Stock
     Purchase Plan (the "DRP") or of Trust Account Shares and DPC Shares), any
     shares of the capital stock of Sterling or any of its consolidated
     subsidiaries or any securities convertible into or exercisable for any
     shares of the capital stock of Sterling or any of its consolidated
     subsidiaries;
    
 
          (c) issue, deliver or sell, or authorize or propose the issuance,
     delivery or sale of, any shares of its capital stock or any securities
     convertible into or exercisable for, or any rights, warrants or options to
     acquire, any such shares, or enter into any agreement with respect to any
     of the foregoing, other than (i) the issuance of Sterling Common Stock
     pursuant to stock options or similar rights to acquire Sterling Common
     Stock granted pursuant to the Sterling Stock Option Plan and outstanding
     prior to October 11, 1993, or (ii) the sale of Sterling Common Stock under
     the DRP or the ESOP, in each case in accordance with the terms in effect on
     October 11, 1993;

     or otherwise acquire any assets, other than in connection with
     foreclosures, settlements in lieu of foreclosure or troubled loan or debt
     restructurings in the ordinary course of business, which would be material
     to Sterling;
 
          (i) take any action that is intended or would result in any of its
     representations and warranties set forth in the Merger Agreement being or
     becoming untrue in any material respect, or in any of the conditions to the
     Merger not being satisfied, or in a violation of any provision of the
     Merger Agreement or the Bank Merger Agreement, except, in every case, as
     may be required by applicable law;
 
          (j) change its methods of accounting in effect at June 30, 1993,

     without first conducting a Phase I environmental assessment of the
     property; or foreclose upon such commercial real estate if such

     likely to result in a material adverse change in or effect on the business,
     financial condition or results of operations of Sterling and its
     subsidiaries taken as a whole, other than any such effect attributable to
     or resulting from changes in interest rates or general economic conditions
     (a "Material Adverse Effect"); or
    
 
   
          (s) agree to do any of the foregoing.

          (d) The registration statement of which this Proxy
     Statement-Prospectus forms a part shall have become effective and shall not
     be subject to an actual or threatened stop order;
    
 
   
          (e) No order, injunction or decree issued by any court or agency of
     competent jurisdiction preventing the consummation of the Merger or the
     other transactions contemplated by the Merger Agreement shall be in effect
     and no statute, rule, regulation, order, injunction or decree shall have
     been enacted or enforced by any court, administrative agency or commission

          (f) Sterling shall have received an opinion of its counsel, dated as
     of the Effective Time, that (i) the Merger will constitute a

          (g) Fleet and Sterling shall have each received a letter from KPMG

          (i) The representations and warranties of each party to the Merger

     representations and warranties to be deemed true and correct unless the
     failure of such representations and warranties to be true and correct,
     without giving effect to any exception relating to materiality, represents
     in the aggregate, a Material Adverse Effect) and each party shall have
     performed its obligations under the Merger Agreement.
    
 
STRUCTURE OF THE BANK MERGER
 
   
     Although not a condition to consummation of the Merger, the Merger
Agreement contemplates that immediately following the consummation of the
Merger, and subject to requisite regulatory approvals, the Bank will merge with
and into the Surviving Bank pursuant to the Bank Merger Agreement. In the Bank
Merger, the outstanding shares of common stock of the Bank will be exchanged for
certain preferred stock of Fleet Banking Group, Inc. ("Fleet Banking Group"), a
wholly-owned subsidiary of Fleet and the holder of all of the outstanding stock
of each of Surviving Bank and Fleet-CT.
    
 
   
STOCK OPTION AGREEMENT
    
 
   
     Grant of Option.  Concurrently with the execution of the Merger Agreement,
Fleet and Sterling entered into the Stock Option Agreement pursuant to which,
among other things, Sterling granted Fleet the Option to purchase up to 512,943
fully paid and non-assessable shares of Sterling Common Stock (the "Option
Shares"), representing 17.0% of the shares of Sterling Common Stock issued and
outstanding as of October 11, 1993 without giving effect to any shares subject
or issued pursuant to the Option, at a price of $30.50 per share (the "Option
Price"). The aggregate purchase price for the original number of Option Shares
at the original Option Price is $15,644,762.
    
 
   
     Triggering Events; Exercise of Option.  The Stock Option Agreement provides
that Fleet may exercise the Option, in whole or in part, if both an Initial
Triggering Event (as defined below) and a Subsequent Triggering Event (as
defined below) shall have occurred prior to the occurrence of an Exercise
Termination Event (as defined below); provided that Fleet shall have sent to
Sterling written notice of such exercise within 30 days following such
Subsequent Triggering Event. The terms Initial Triggering Event and Subsequent
Triggering Event generally relate to attempts by one or more third parties to
acquire a significant interest in Sterling. In addition, exercise of the Option
is subject to receipt of all required governmental or regulatory approvals,
waivers or consents.
    
 
                                       33
<PAGE>   39
 
     For purposes of the Stock Option Agreement:
 
   
          (a) The term "Initial Triggering Event" means any of the following
     events or transactions occurring after October 11, 1993: (i) Sterling, or
     any of its subsidiaries, without Fleet's prior written consent, enters into
     an agreement to engage in, or Sterling's Board of Directors approves or
     recommends approval of, an Acquisition Transaction (as defined below) with
     any person other than Fleet or its subsidiaries (other than as contemplated
     by the Merger Agreement); (ii) any person, other than Fleet or its
     subsidiaries, Sterling or its subsidiaries or a Schedule 13G Investor (as
     defined in the Stock Option Agreement), acquires beneficial ownership, or
     the right to acquire beneficial ownership, of 10% or more of the
     outstanding shares of Sterling Common Stock if such person beneficially
     owned less than 10% on October 11, 1993, or acquires beneficial ownership
     of an additional 3% if such person beneficially owned 10% or more on
     October 11, 1993; (iii) any person other than Fleet or its subsidiaries has
     made a bona fide proposal to Sterling or its stockholders to engage in an
     Acquisition Transaction by public announcement or written communication
     that shall be or become the subject of public disclosure; or (iv) Sterling
     breaches any covenant or obligation in the Merger Agreement after any
     person, other than Fleet or its subsidiaries, has proposed an Acquisition
     Transaction, and such breach (A) would entitle Fleet to terminate the
     Merger Agreement and (B) is not remedied prior to the date of Fleet's
     notice to Sterling of the exercise of the Option. For purposes of the Stock
     Option Agreement, the term "Acquisition Transaction" means (i) a merger or
     consolidation, or any similar transaction with Sterling or any of its
     subsidiaries; (ii) a purchase, lease or other acquisition of all or
     substantially all of the assets of Sterling or any of its subsidiaries; or
     (iii) a purchase or acquisition of securities representing 10% or more of
     the voting power of Sterling or any of its subsidiaries.
    
 
          (b) The term "Subsequent Triggering Event" means either of the
     following events or transactions occurring after October 11, 1993: (i) the
     acquisition by any person, other than a Schedule 13G Investor, of
     beneficial ownership of 15% or more of the then outstanding shares of
     Sterling Common Stock; or (ii) the occurrence of the Initial Triggering
     Event described above in clause (a)(i), except that the percentage referred
     to in subclause (C) of the definition of "Acquisition Transaction" set
     forth above shall be 15%.
 
   
     The Option will expire upon the occurrence of an "Exercise Termination
Event", defined as: (a) the Effective Time; (b) termination of the Merger
Agreement in accordance with the provisions thereof if such termination occurs
prior to the occurrence of an Initial Triggering Event; or (c) termination of
the Merger Agreement in accordance with the provisions thereof if such
termination occurs after the occurrence of an Initial Triggering Event, except
(i) in the case of termination of the Merger Agreement by Sterling or Fleet
because of the failure to obtain Sterling stockholder approval, the passage of 6
months after termination, or (ii) in the case of termination of the Merger
Agreement by Fleet as a result of an uncured material breach by Sterling of any
of its representations, warranties, covenants or agreements, the passage of 6
months after termination, or (iii) in the case of termination of the Merger
Agreement by Sterling as a result of an uncured material breach by Fleet of any
of its representations, warranties, covenants or agreements, immediately.
    
 
     As of the date of this Proxy Statement-Prospectus, to the best knowledge of
Fleet and Sterling, no Initial Triggering Event or Subsequent Triggering Event
has occurred.
 
     In the event of any change in the shares of Sterling Common Stock by reason
of a stock dividend, split-up, merger, recapitalization, combination,
subdivision, conversion, exchange of shares or similar transaction, the type and
number of Option Shares will be adjusted so that Fleet will receive upon
exercise of the Option the number and class of shares or other securities or
property that Fleet would have held immediately after such event if the Option
had been exercised immediately prior to such event, or the record date therefor,
as applicable, and the Option Price will be adjusted accordingly. The Board of
Directors of Sterling may make such increases in the number of Option Shares, in
addition to those made in accordance with the events described in the
immediately preceding sentence, in order to avoid taxation of any dividend of
stock or stock rights or any event treated as such for Federal income tax
purposes to the recipients. Whenever the number of Option Shares (or other
securities) purchasable upon exercise of the Option is adjusted following the
changes set forth above, the Option Price shall be adjusted by multiplying the
Option Price by a fraction, the
 
                                       34
<PAGE>   40
 
numerator of which shall be equal to the number of Option Shares prior to the
adjustment and the denominator of which shall be equal to the number of Option
Shares (or other securities) purchasable after the adjustment.
 
   
     In the event that additional shares of Sterling Common Stock are issued or
otherwise become outstanding after October 11, 1993 (for reasons other than as
set forth in the preceding paragraph or as a result of the exercise of the
Option), the number of shares of Sterling Common Stock under the Option is
subject to upward adjustment to 17% of the number of shares of Sterling Common
Stock issued and outstanding (without giving effect to the exercise of the
Option).
    
 
   
     Repurchase of Option.  Upon the occurrence of a Subsequent Triggering Event
that occurs prior to the occurrence of an Exercise Termination Event, at the
request of Fleet or any subsequent holder of the Option or any owner of Option
Shares (the "Owner") delivered within 30 days of the Subsequent Triggering Event
(such 30-day period being subject to extension under certain circumstances),
Sterling (a) shall repurchase the Option from Fleet or such holder at a price
(the "Option Repurchase Price") equal to the amount by which (i) the
market/offer price (as defined in the Stock Option Agreement) exceeds (ii) the
Option Price, multiplied by the number of shares for which the Option may then
be exercised, plus, to the extent not previously reimbursed, Fleet's reasonable
out of pocket expenses incurred in connection with the transactions contemplated
by the Merger Agreement (the "out of pocket expenses") and (b) shall repurchase
such number of Option Shares from any Owner as the Owner shall designate at a
price (the "Option Share Repurchase Price") equal to the greater of (i) the
market/offer price or (ii) the average exercise price per share paid by the
Owner for the Option Shares so designated, plus Fleet's out of pocket expenses.
    
 
   
     Conversion of Option.  In the event that prior to an Exercise Termination
Event, Sterling enters into any agreement (a) to consolidate or merge with any
person, other than Fleet or one of its subsidiaries, such that Sterling is not
the surviving corporation; (b) to permit any person, other than Fleet or one of
its subsidiaries, to merge into Sterling and Sterling is the surviving
corporation, but in connection with such merger, the outstanding shares of
Sterling Common Stock are changed into or exchanged for stock or other
securities of any other person or cash or any other property, or the outstanding
shares of Sterling Common Stock after such merger shall represent less than 50%
of the outstanding shares and share equivalents of the merged corporation; or
(c) to sell or otherwise transfer all or substantially all of its assets to any
person, other than Fleet or any of its subsidiaries, then, and in each such
case, the agreement governing such transaction must provide that, upon
consummation of the transaction, the Option will be converted into or exchanged
for an option (the "Substitute Option") to purchase securities, at the election
of Fleet, of either the acquiring person or any person that controls the
acquiring person. At the request of the holder of the Substitute Option, the
issuer of the Substitute Option shall repurchase it at a price, and subject to
such other terms and conditions, as set forth in the Stock Option Agreement.
    
 
   
     Registration Rights.  Within 30 days after the occurrence of a Subsequent
Triggering Event, Fleet may request Sterling to prepare, file and keep current
with respect to the Option Shares, a registration statement with the Commission.
Sterling is required to use its best efforts to cause such registration
statement to become effective and then to remain effective for 180 days or such
shorter time as may be reasonably necessary to effect such sales or other
dispositions of Option Shares. Fleet has the right to demand two such
registrations.
    
 
   
     Assignment of Option.  Neither Fleet nor Sterling may assign any of its
rights or obligations under the Stock Option Agreement or the Option to any
other person without the express written consent of the other party.
    
 
   
     Additional Provisions.  Certain rights and obligations of Fleet and
Sterling under the Stock Option Agreement are subject to receipt of required
regulatory approvals. As noted below under "THE MERGER -- Regulatory Matters",
the approval of the Federal Reserve Board and the Massachusetts BBI is required
for the acquisition by Fleet of more than 5% of the outstanding shares of
Sterling Common Stock. Accordingly, Fleet has included or will include in its
applications with the Federal Reserve Board and the Massachusetts BBI a request
for approval of the right of Fleet to exercise its rights under the Stock Option
Agreement, including its right to purchase more than 5% of the outstanding
shares of Sterling Common Stock.
    
 
                                       35
<PAGE>   41
 
   
     The Stock Option Agreement provides that, (a) in the case of the Option, at
any time from the occurrence of a Subsequent Triggering Event until the
expiration of the Option and (b) in the case of shares of Sterling Common Stock
or other securities acquired by Fleet pursuant to an exercise of the Option,
prior to the end of the 24-month period following expiration of the Option,
Sterling has a right of first refusal with respect to any transfer by Fleet of
the Option or shares acquired pursuant to the exercise thereof.
    
 
   
     The Stock Option Agreement and the Option exercise price were the result of
arms' length negotiations between Fleet and Sterling. The Stock Option Agreement
was entered into at the request of Fleet to increase the likelihood that the
Merger will be consummated in accordance with the terms of the Merger Agreement
by making it more difficult and more expensive for a third party to attempt to
acquire control of Sterling.
    
 
STERLING SHAREHOLDER RIGHTS AGREEMENT
 
   
     On January 23, 1989, the Board of Directors of Sterling declared a dividend
distribution of one preferred stock purchase right (a "Right") for each
outstanding share of Sterling Common Stock to stockholders of record. Each Right
entitles the registered holder to purchase from Sterling a unit consisting of
one-hundredth of a share (a "Unit") of Series A Junior Participating Cumulative
Preferred Stock, par value $0.10 per share (the "Series A Preferred Stock"), at
a cash exercise price of $51.00 per Unit, subject to adjustment. The description
and terms of the Rights are set forth in the Rights Agreement.
    
 
   
     Immediately prior to the execution of the Merger Agreement, Sterling
amended the Rights Agreement (the "Amendment"). The Amendment provides, among
other things, that neither Fleet nor any of its Affiliates or Associates (as
such terms are defined in the Rights Agreement) shall be deemed an Acquiring
Person (as defined in the Rights Agreement) and no "Stock Acquisition Date",
"Distribution Date", "Section 11(a)(ii) Event" or "Section 13 Event" (as such
terms are defined in the Rights Agreement) shall occur as a result of (a) the
execution and delivery of the Merger Agreement as the same may be amended from
time to time, or the Stock Option Agreement as the same may be amended from time
to time; (b) any action taken by Fleet or any of its Affiliates or Associates in
accordance with the provisions of the Merger Agreement or the Stock Option
Agreement (including, without limitation, any transfer of all or any portion of
the Option granted pursuant to the Stock Option Agreement or the shares issuable
upon exercise of such Option, to the extent such transfer is permitted under the
Stock Option Agreement); or (c) the consummation of the Merger in accordance
with the provisions of the Merger Agreement. The Amendment also provides that
the Expiration Date (as such term is defined in the Rights Agreement) shall be
the earliest of (a) the close of business on January 23, 1999; (b) the time at
which the Rights are redeemed as provided in the Rights Agreement; or (c) the
Effective Time.
    
 
REGULATORY MATTERS
 
   
     Federal Reserve Board.  The Merger is subject to approval by the Federal
Reserve Board pursuant to Section 3 of the Bank Holding Company Act of 1956, as
amended (the "BHCA"). Fleet and Sterling intend to seek and have agreed to use
their best efforts to obtain such approval as well as the approvals discussed
below. Assuming Federal Reserve Board approval, the Merger may not be
consummated until 30 days after such approval, during which time the Department
of Justice may challenge the Merger on antitrust grounds.
    
 
     The Federal Reserve Board is prohibited from approving any application
under the applicable statutes:
 
   
          (a) which would result in a monopoly or which would be in furtherance
     of any combination or conspiracy to monopolize or to attempt to monopolize
     the business of banking in any part of the United States; or
    
 
          (b) the effect of which in any section of the United States may be
     substantially to lessen competition, or to tend to create a monopoly, or
     result in a restraint of trade, unless the Federal Reserve Board finds that
     the anti-competitive effects of the transaction are clearly outweighed in
     the public interest by the probable effect of the transaction in meeting
     the convenience and needs of the communities to be served.
 
                                       36
<PAGE>   42
 
Additionally, in reviewing an application under the applicable statutes, the
Federal Reserve Board will consider the financial and managerial resources of
the institutions and their subsidiary banks and the convenience and needs of the
communities to be served. As part of, or in addition to, consideration of the
above factors, it is anticipated that the Federal Reserve Board will consider
the regulatory status of Fleet and Sterling, current and projected economic
conditions in the New England region and the overall capital and safety and
soundness standards established by the Federal Deposit Insurance Corporation
Improvement Act of 1991 ("FDICIA") and the regulations promulgated thereunder.
 
     In addition, under the Community Reinvestment Act of 1977, as amended (the
"CRA"), the Federal Reserve Board must take into account the record of
performance of each of Fleet and Sterling in meeting the credit needs of the
entire community, including low and moderate income neighborhoods, served by
each of such institutions.
 
     The implementing Federal Reserve Board regulations require the Federal
Reserve Board to furnish notice and a copy of the application to the primary
banking supervisor of the bank to be acquired, which in Sterling's case is the
Federal Deposit Insurance Corporation (the "FDIC"). The primary banking
supervisor has 30 days to submit its views and recommendations to the Federal
Reserve Board. The Federal Reserve Board is required to hold a public hearing in
the event it receives a written recommendation of disapproval of the application
from the primary banking supervisor within such 30-day period. Furthermore, the
BHCA and implementing Federal Reserve Board regulations require publication of
notice of, and the opportunity for public comment on, the application submitted
by Fleet for approval of the Merger and authorize the Federal Reserve Board to
permit interested parties to intervene in the proceedings and to hold a public
hearing in connection therewith if the Federal Reserve Board determines that
such a hearing would be appropriate. Any such intervention by third parties
could prolong the period during which the application is subject to review by
the Federal Reserve Board.
 
     As noted above, the Merger may not be consummated until 30 days after
Federal Reserve Board approval, during which time the Department of Justice may
challenge the Merger on antitrust grounds. The commencement of an antitrust
action by the Department of Justice would stay the effectiveness of Federal
Reserve Board approval unless a court specifically orders otherwise. In
reviewing the Merger, the Department of Justice could analyze the Merger's
effect on competition differently than the Federal Reserve Board, and thus it is
possible that the Department of Justice could reach a different conclusion than
the Federal Reserve Board regarding the Merger's competitive effects. Failure of
the Department of Justice to object to the Merger does not prevent the filing of
antitrust actions by private persons.
 
     Fleet's right to exercise the Option is also subject to the prior approval
of the Federal Reserve Board, to the extent that the exercise of the Option
would result in Fleet owning more than 5% of the outstanding shares of Sterling
Common Stock. In considering whether to approve Fleet's right to exercise the
Option, including its right to purchase more than 5% of the outstanding shares
of Sterling Common Stock, the Federal Reserve Board would generally apply the
same statutory criteria it would apply to its consideration of approval of the
Merger.
 
   
     Massachusetts BBI.  In addition, the Merger requires the approval of the
Massachusetts BBI, under Sections 2 and 4 of Chapter 167A of the Massachusetts
General Laws. In determining whether or not to approve the Merger, the
Massachusetts BBI's approval is essentially based upon its determination that
such proposed acquisition does not unreasonably affect competition among
Massachusetts banking institutions and that it promotes public convenience and
advantage. In making such a determination, the BBI must consider, but is not
limited to, a showing of net new benefits including initial capital investments,
job creation plans, consumer and business services and commitments to maintain
and open branch offices within a bank's statutorily-delineated local community.
The statute also requires that the Massachusetts BBI receive notice from the
Massachusetts Housing Partnership Fund (the "MHPF") that arrangements
satisfactory to the MHPF have been made for the proposed acquiror to make 0.9%
of its assets located in Massachusetts available for call by MHPF for a period
of ten years for purposes of funding various affordable housing programs.
    
 
                                       37
<PAGE>   43
 
     Under Section 2 of Chapter 167A of the Massachusetts General Laws, the
right of Fleet to exercise the Option is subject to the prior approval of the
Massachusetts BBI, to the extent that the exercise of the Option would result in
Fleet indirectly owning more than 5% of the voting stock of the Bank. In
determining whether to approve Fleet's right to exercise the Option, the
Massachusetts BBI would generally apply the same statutory criteria it would
apply to its consideration of approval of the Merger.
 
   
     Fleet has filed a draft application with the Federal Reserve Board and
intends to file an application with the Massachusetts BBI after the date hereof,
in each case with respect to the Merger as well as with respect to its right to
exercise the Option. The Merger will not proceed until all regulatory approvals
required to consummate the Merger have been obtained, such approvals are in full
force and effect and all statutory waiting periods in respect thereof have
expired. There can be no assurance that the Merger will be approved by the
Federal Reserve Board or the Massachusetts BBI. If such approvals are received,
there can be no assurance as to the date of such approvals or the absence of any
litigation challenging such approvals. Fleet and Sterling are not aware of any
other governmental approvals or actions that are required prior to the parties'
consummation of the Merger. It is presently contemplated that if any such
additional governmental approvals or actions are required, such approvals or
actions will be sought. There can be no assurance, however, that any such
additional approvals or actions will be obtained.
    
 
   
     While it is not a condition to the consummation of the Merger, the Merger
Agreement contemplates that the Bank Merger will take place immediately
following the consummation of the Merger. In order to effect the Bank Merger,
Fleet will need, among other things, the approval of the OCC under the Bank
Merger Act. Fleet intends to file an application with the OCC after the date
hereof.
    
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
   
     Neither Fleet nor Sterling has requested or will receive an advance ruling
from the Internal Revenue Service as to the tax consequences of the Merger.
Consummation of the Merger is conditioned on the delivery of the opinion of
Goodwin, Procter & Hoar, counsel to Sterling, dated as of the Effective Time,
which opinion may be based on various facts and representations and subject to
various assumptions, that for federal income tax purposes, the Merger will
constitute a reorganization within the meaning of Section 368(a) of the Code,
and Fleet and Sterling each will be a party to the reorganization within the
meaning of Section 368(b) of the Code and accordingly no gain or loss will be
recognized by a Sterling stockholder upon exchange of his or her Sterling Common
Stock for Fleet Common Stock, except in respect of cash received in lieu of a
fractional share interest in Fleet Common Stock.

     If the Merger constitutes a reorganization under Section 368(a) of the
Code, the following would be the material federal income tax consequences which
would result from the Merger:
 
          a. No gain or loss will be recognized by Sterling or Fleet by reason
     of the Merger;
 
          b. No gain or loss will be recognized by a Sterling stockholder upon
     the exchange of his or her Sterling Common Stock for Fleet Common Stock,
     except that a Sterling stockholder who receives cash proceeds in lieu of a
     fractional share interest in Fleet Common Stock will recognize gain or loss
     equal to the difference between such proceeds and the tax basis allocated
     to the fractional share interest, and such gain or loss will constitute
     capital gain or loss if such stockholder's Sterling Common Stock is held as
     a capital asset at the Effective Time;
 
          c. The tax basis of the Fleet Common Stock received by a Sterling
     stockholder who exchanges his or her Sterling Common Stock for Fleet Common
     Stock will be the same as such stockholder's tax basis in the Sterling
     Common Stock surrendered in exchange therefor, decreased by the tax basis
     allocated to any such fractional share interest; and
 
          d. The holding period of the Fleet Common Stock received by a Sterling
     stockholder will include the period during which the Sterling Common Stock
     surrendered in exchange therefor was held (provided that such Sterling
     Common Stock was held by such Sterling stockholder as a capital asset at
     the Effective Time).
    
 
                                       38
<PAGE>   44
 
     The discussion set forth above is included for general information only and
is not a complete description of all the tax consequences of the Merger. It may
not address federal income tax considerations that may affect the treatment of a
Sterling stockholder who acquired Sterling Common Stock pursuant to an employee
stock option, and it does not address the state, local or foreign tax aspects of
the Merger. The discussion is based on currently existing provisions of the
Code, existing and proposed U.S. Treasury regulations thereunder and current
administrative rulings and court decisions. All of the foregoing are subject to
change and any such change could affect the continuing validity of this
discussion. Sterling stockholders should consult their own tax advisors with
respect to the specific tax consequences of the Merger to them, including the
application and effect of state, local and foreign tax laws.
 
ACCOUNTING TREATMENT
 
   
     It is anticipated that the Merger will be accounted for as a
"pooling-of-interests" transaction under generally accepted accounting
principles. Under such method of accounting, holders of Sterling Common Stock
will be deemed to have combined their existing voting common stock interest with
that of holders of Fleet Common Stock by exchanging their shares for shares of
Fleet Common Stock. Accordingly, the book value of the assets, liabilities and
stockholders' equity of Sterling, as reported on its consolidated balance sheet,
will be carried over to the consolidated balance sheet of Fleet and no goodwill
will be created. Fleet will be able to include in its consolidated income the
consolidated income of Sterling for the entire fiscal year in which the Merger
occurs; however, certain expenses incurred to effect the Merger must be treated
by Fleet as current charges against income rather than adjustments to its
balance sheet.
    
 
     In order for the Merger to qualify for pooling-of-interests accounting
treatment, among other criteria, substantially all (90% or more) of the
outstanding Sterling Common Stock must be exchanged for Fleet Common Stock.
Sterling and Fleet have agreed to use their best efforts to cause the Merger to
qualify for pooling-of-interests treatment. It is a condition to consummation of
the Merger that Fleet and Sterling shall have each received a letter from KPMG
Peat Marwick and Arthur Andersen & Co., respectively, to the effect that the
Merger qualifies for pooling-of-interests accounting treatment.
 
TERMINATION OF THE MERGER AGREEMENT
 
   
     The Merger Agreement provides that the Merger may be terminated at any time
prior to the Effective Time (whether before or after stockholder approval) by
mutual consent of Fleet and Sterling by a majority vote of each company's entire
Board of Directors. Subject to certain limitations in cases where the party
seeking termination is in breach of the Merger Agreement, the Merger Agreement
may also be terminated by Fleet or Sterling (a) forty-five days after the date
on which any request or application for a regulatory approval required to
consummate the Merger shall have been denied or withdrawn at the request or
recommendation of any governmental entity which must grant such regulatory
approval, unless within the forty-five day period following such denial or
withdrawal, a petition for rehearing or an amended application has been filed
with such governmental entity; (b) if any governmental entity shall have issued
a final nonappealable order enjoining or otherwise prohibiting the consummation
of any of the transactions contemplated by the Merger Agreement; (c) if the
Effective Time has not occurred by September 30, 1994; (d) if there is a
material breach by the other party of any representation, warranty, covenant or
agreement contained in the Merger Agreement which is not timely cured; or (e) if
the vote of Sterling's stockholders shall not be sufficient to approve the
Merger Agreement. Sterling may also terminate the Merger Agreement in the event
the Average Closing Price is equal to or less than $25.59, unless Fleet elects
to adopt the Adjusted Maximum Exchange Ratio as the Exchange Ratio.
    
 
   
WAIVER AND AMENDMENT OF THE MERGER AGREEMENT
    
 
   
     Waiver.  Fleet and Sterling, with the authorization of their respective
Boards of Directors, may to the extent legally allowable, (a) extend the time
for the performance of any of the obligations or other acts required of the
other party contained in the Merger Agreement; (b) waive any inaccuracies in the
representations and warranties of the other party contained in the Merger
Agreement or in any document delivered pursuant to the Merger Agreement; or (c)
waive compliance by the other party of any of its
    
 
                                       39
<PAGE>   45
 
agreements or conditions contained in the Merger Agreement, except that after
Sterling stockholder approval, no extension or waiver shall reduce the amount or
change the form of consideration to be delivered to each of Sterling's
stockholders as contemplated by the Merger Agreement without further approval of
Sterling's stockholders, except as contemplated by the Merger Agreement.
 
   
     AMENDMENT.  Any term or provision of the Merger Agreement may be amended in
writing (subject to compliance with applicable law) at any time, except that
after Sterling stockholder approval, no amendment shall reduce the amount or
change the form of the consideration to be delivered to each of Sterling's
stockholders under the Merger Agreement without further approval of Sterling's
stockholders, other than as contemplated by the Merger Agreement. In addition,
Delaware law prohibits, among other things, any change in any of the terms and
conditions of the Merger Agreement if such change or alteration would adversely
effect any holder of Sterling Common Stock.
    
 
EFFECT ON EMPLOYEE BENEFITS
 
   
     The Merger Agreement requires Fleet and the Surviving Bank to offer
employment to all employees of Sterling and its subsidiaries and to honor all
employment, severance and other compensation agreements disclosed to Fleet in
the Merger Agreement in accordance with their terms. See "-- Interests of
Certain Persons in the Merger". The Merger Agreement also provides that, after
the Merger, Fleet and the Surviving Bank will provide Sterling employees with
the same employee benefit plans provided to Fleet's own employees, and to credit
Sterling employees that become participants in any employee benefit plans of the
Surviving Bank, Fleet or any of its subsidiaries with all prior years of service
with Sterling or any of its subsidiaries to the extent such service was
recognized by Sterling or any of its subsidiaries under any of its plans.
    
 
   
     In addition to the severance and benefit arrangements discussed above,
Fleet has also agreed to provide employees of Sterling and its subsidiaries who
are terminated on or within two years after the Effective Time; (a) severance
equal to two (2) weeks salary or wages for each year or partial year of service
of such terminated employee to Sterling, the Bank (or any entity for which
Sterling or the Bank credited the employee's years of service with such entity),
Fleet and any subsidiaries of Fleet, subject to a minimum severance amount; and
(b) continuation of health benefits for one year after termination on the same
terms and conditions as though they had remained active employees, as well as
continuation benefits (such as COBRA) thereafter.
    
 
   
     In addition, Fleet has agreed that, at the Effective Time, all options held
by optionees under the Sterling Stock Option Plan which are outstanding at the
Effective Time will be converted into and become options under the Fleet Stock
Option Plan on the same terms and conditions as the Sterling Stock Option Plan,
except that the number of shares subject to such Fleet options shall be the
number of shares subject to the Sterling options multiplied by the Exchange
Ratio and that the exercise price per share under the Fleet options shall be
equal to the exercise price per share under the Sterling options divided by the
Exchange Ratio.
    
 
   
     The Merger Agreement provides that, effective as of the Effective Time (or
as soon thereafter as practicable), the ESOP will be terminated in accordance
with applicable law and regulations. If the ESOP is not fully funded prior to
the Effective Time, any loan balance will be repaid from the proceeds of
unallocated shares of Sterling Common Stock held by the ESOP.
    
 
   
     The Merger Agreement provides that Sterling, and after the Effective Time,
Fleet, shall indemnify and hold harmless, as and to the fullest extent permitted
by applicable law, each person who was at the date of the Merger Agreement, or
has been at any time prior to the date of the Merger Agreement, or who becomes
prior to the Effective Time, a director, officer or employee of Sterling or any
of its subsidiaries (the "Indemnified Parties") against any losses, claims,
damages, liabilities, costs, expenses (including reasonable attorney's fees and
expenses), judgments, fines and amounts paid in settlement in connection with
any threatened or actual claim, action, suit, proceeding or investigation
(whether asserted or arising before or after the Effective Time), whether civil,
criminal or administrative, including, without limitation, any such claim,
action, suit, proceeding or investigation in which each such Indemnified Party
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 (a) the fact that he is or
was a director, officer
    
 
                                       40
<PAGE>   46
 
   
or employee of Sterling, any of its subsidiaries or any of their respective
predecessors or (b) the Merger Agreement or any of the transactions contemplated
thereby. Fleet has also agreed that all rights to indemnification existing in
favor of the employees of Sterling and its subsidiaries in such companies'
respective charter documents or by-laws or similar organizational document, as
in effect on October 11, 1993 will survive the Merger and continue in full force
and effect for a period of not less than six years from the Effective Time with
respect to matters occurring prior to the Effective Time and to use its best
efforts to maintain in effect for not less than three years from the Effective
Time, policies of directors' and officers' liability insurance maintained by
Sterling and its subsidiaries or to substitute comparable policies, covering
officers and directors of Sterling immediately prior to the Effective Time with
respect to acts or omissions occurring at or prior to the Effective Time which
were committed by such officers and directors in their capacity as such, each
subject to certain amount limitations. See "-- Interests of Certain Persons in
the Merger".
    
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In connection with the Merger, Fleet has agreed to provide certain benefits
and make certain severance payments to all employees of Sterling and its
subsidiaries. See "-- Effect on Employee Benefits". Fleet also has agreed to
take certain actions regarding the existing employment and severance
arrangements of certain officers of Sterling and the Bank. The following section
describes certain arrangements that Sterling and the Bank had entered into prior
to the execution of the Merger Agreement with its executive officers and further
describes the actions that Fleet has agreed to take in connection with these
pre-existing agreements. The following section also describes other actions
Fleet has agreed to take with respect to certain officers of Sterling and the
Bank. Fleet will take the actions described below upon the consummation of the
Merger.
 
   
     Employment Agreements.  Sterling and the Bank (collectively, the
"Employers") are parties to an employment agreement with John C. Warren and the
Bank is a party to an employment agreement with each of Ernest A. Maher, David
Hadden, Jr., Gene A. Miller and John F. Treanor (collectively, the "Employment
Agreements"). Mr. Warren's employment agreement became effective as of October
1, 1989, Mr. Hadden's and Ms. Miller's employment agreements became effective as
of February 1, 1991, Mr. Treanor's employment agreement became effective as of
March 26, 1991 and Mr. Maher's employment agreement became effective as of
October 1, 1991. The Employment Agreements provide that each of the foregoing
officers will receive minimum annual compensation in amounts ranging from
$84,000 to $160,000, subject to increase in accordance with the respective
Employer's usual practice with respect to review of compensation of its senior
executives. Mr. Warren's employment agreement had an initial three year term.
Mr. Maher's, Mr. Hadden's, Ms. Miller's and Mr. Treanor's Employment Agreements
had an initial one year term. Each of the Employment Agreements has been
extended pursuant to provisions which provide for automatic extensions for
additional periods of one year, beginning at the first anniversary of the
Employment Agreement. Terms are not extended if the officer or the respective
Employer gives written notice to the other, prior to the first anniversary of
the Employment Agreement or any anniversary thereafter, of his/her or its
election not to extend the Employment Agreement. The respective Employers, by
two-thirds vote of all of the members of the respective Employer's Board of
Directors, may terminate an officer's employment without further liability for
"cause", as defined in the respective Employment Agreement. In the event of
termination of employment by the officer because the respective Employer fails
to make salary payments as provided in each Employment Agreement or a material
breach of any other provision of the Employment Agreement by the respective
Employer, or by the respective Employer without cause, the officers would each
be entitled to receive his or her full salary and would continue to be treated
as an employee for purposes of the respective Employer's benefit plans
(excluding cash bonus plans) for the duration of what would otherwise have been
the term of his employment under the Employment Agreement with respect to Mr.
Warren and for one year subsequent to the date of termination with respect to
Mr. Maher, Mr. Hadden, Ms. Miller and Mr. Treanor.
    
 
     Notwithstanding the foregoing provisions, each of the officers who is a
party to an Employment Agreement has indicated that, in the event of termination
of such officer's employment under the circumstances triggering termination
benefits, he or she intends to elect to receive the severance benefits pursuant
to the Special Termination Agreement to which he or she is a party, as described
below, in lieu of any termination benefits under his or her Employment
Agreement. As a consequence of such election and the
 
                                       41
<PAGE>   47
 
terms of the Employment Agreements, neither Fleet nor any of the Sterling
officers is expected to have any further obligations under the Employment
Agreements after the Effective Time.
 
   
     Termination Agreements.  The Employers are also parties to special
termination agreements with each of Mr. Warren and Mr. Maher effective as of
October 1, 1989, with Ms. Miller and Mr. Hadden effective as of February 1, 1991
and with Mr. Treanor effective as of March 26, 1991 (the "Special Termination
Agreements"). The Special Termination Agreements provide that if there is a
"Change in Control" of the Employers, which is generally defined to mean (a) a
Change in Control that Sterling would be required to report in Item 1 of Form
8-K under the Exchange Act; (b) the acquisition by a person or group of persons
of beneficial ownership of stock of either of the Employers representing 25% or
more of the total number of votes that may be cast for the election of directors
of either of the Employers during the term of the Special Termination
Agreements, which is not approved by the two-thirds vote of all of the directors
of the Employers as provided in the Special Termination Agreements; or (c) a
Change in Control if, as a result of, or in connection with, any tender or
exchange offer, merger or other business combination, sale of assets or
contested election, or any combination of the foregoing transactions, persons
who were directors of either Employer before such transaction shall cease to
constitute a majority of the Board of Directors of the respective Employer or
the successor institution, and if at any time during the three year period
following the Change in Control, either of the Employers were to terminate the
officer's employment for any reason other than for death, deliberate dishonesty
with respect to either Employer or conviction of a crime involving moral
turpitude, or the officer were to resign from his or her own employment
following his or her demotion, loss of title, office or significant authority,
or a reduction in his or her annual compensation (a "Termination Event"), the
officer would be entitled to receive certain severance benefits provided to him
or her in his or her respective Special Termination Agreement. In the case of
the occurrence of such a Termination Event, the Employers would be obligated to
pay to Mr. Warren a lump sum payment in an amount equal to approximately three
times the "base amount", as defined in Section 280G(b)(3) of the Code and the
Employers would be obligated to pay to Ms. Miller, Mr. Hadden, Mr. Treanor and
Mr. Maher a lump sum payment equal to his or her annual salary at the highest
annual rate in effect at any time during the period from one day prior to the
Change in Control to the date of the Termination Event plus the amount of the
most recent annual bonus (if any) paid to him or her. Fleet has agreed in the
Merger Agreement to honor the Special Termination Agreements in accordance with
their terms, and has also agreed for itself and its subsidiaries that the
consummation of the transactions contemplated by the Merger Agreement is a
"Change of Control" as defined in the Special Termination Agreements.
    
 
   
     Continuation of Rights to Indemnification, Limitation of Liability, D & O
Insurance.  In the Merger Agreement, Fleet has also agreed (a) that all rights
to indemnification and all limitations on personal liability existing in favor
of the employees, directors and officers of Sterling and its subsidiaries as
provided in such companies' respective charter documents or by-laws or similar
organizational document, as in effect on October 11, 1993 will survive the
Merger and continue in full force and effect for a period of not less than six
years from the Effective Time with respect to matters occurring prior to the
Effective Time and (b) to use its best efforts to maintain in effect for not
less than three years from the Effective Time, policies of directors' and
officers' liability insurance maintained by Sterling and its subsidiaries or to
substitute comparable policies, covering officers and directors of Sterling
immediately prior to the Effective Time with respect to acts or omissions
occurring at or prior to the Effective Time which were committed by such
officers and directors in their capacity as such, except that Fleet is not
required to expend more than 200% of the amount currently expended by Sterling
on such insurance, in each case with respect to matters occurring prior to the
Merger.
    
 
   
     Cash Bonus Pool.  On September 17, 1993, following Sterling's receipt of an
informal indication of interest from a financial institution regarding a
possible acquisition of Sterling, the Personnel Committee of Sterling's Board of
Directors (the "Committee"), which consists solely of disinterested directors
and performs the function of a compensation committee, met to discuss
compensation matters in connection with such a merger or acquisition. At that
meeting, the Committee recommended approval by the Board of Directors of a cash
bonus pool in connection with a possible merger or acquisition, which would act
as a retention incentive for officers and employees of Sterling and/or the Bank.
On October 8, 1993, the full Board authorized the establishment of a $1.25
million cash bonus pool, which is to be allocated in connection with the Merger
to
    
 
                                       42
<PAGE>   48
 
   
certain officers and employees of Sterling and/or the Bank as determined by the
Committee that remain employed with Sterling and/or the Bank until the
consummation of the Merger. The cash bonus pool is distinct from the annual
incentive bonus plan which Sterling maintains for its executive officers.
    
 
RESALE OF FLEET COMMON STOCK
 
   
     The Fleet Common Stock issued pursuant to the Merger will be freely
transferable under the Securities Act, except for shares issued to any Sterling
stockholder who may be deemed to be an affiliate (an "Affiliate") of Sterling
for purposes of Rule 145 under the Securities Act. Affiliates are generally
defined as persons (generally executive officers and directors) who control, are
controlled by, or are under common control with (a) Fleet or Sterling at the
time of the Special Meeting or (b) Fleet at or after the Effective Time.
    
 
   
     Rules 144 and 145 promulgated by the Commission under the Securities Act
restrict the sale of Fleet Common Stock received in the Merger by Affiliates and
certain of their family members and related interests. Generally speaking,
during the two years following the Effective Time, Affiliates of Sterling,
provided they are not Affiliates of Fleet, may publicly resell the Fleet Common
Stock received by them in the Merger, subject to certain limitations as to the
amount of Fleet Common Stock sold by them in any three-month period and as to
the manner of sale. After the two-year period, such Affiliates of Sterling who
are not Affiliates of Fleet may resell their shares without such restrictions so
long as there is adequate current public information with respect to Fleet as
required by Rule 144. Persons who become Affiliates of Fleet prior to, at or
after the Effective Time may publicly resell the Fleet Common Stock received by
them in the Merger subject to similar limitations and subject to certain filing
requirements specified in Rule 144. The ability of Affiliates to resell shares
of Fleet Common Stock received in the Merger under Rule 144 or 145 as summarized
herein generally will be subject to Fleet's having satisfied its Exchange Act
reporting requirements for specified periods prior to the time of sale.
Affiliates also would be permitted to resell Fleet Common Stock received in the
Merger pursuant to an effective registration statement under the Securities Act
or another available exemption from the Securities Act registration
requirements.
    
 
   
     This Proxy Statement-Prospectus does not cover any resales of Fleet Common
Stock received by persons who may be deemed to be Affiliates of Fleet or
Sterling. The Merger Agreement provides that Sterling shall use all reasonable
efforts to cause each such Affiliate of Sterling to deliver to Fleet prior to
the date of the Special Meeting an agreement providing that such Affiliate will
not sell, pledge, transfer or otherwise dispose of any Fleet Common Stock
received in the Merger except in compliance with the Securities Act and in
addition, to protect the pooling-of-interests accounting treatment of the
Merger, the Merger Agreement provides that each of Sterling and Fleet shall use
all reasonable efforts to cause such Sterling Affiliates and Affiliates of
Fleet, respectively, to deliver to the other party prior to the Special Meeting
an agreement of such Sterling Affiliates and Fleet Affiliates, as the case may
be, not to sell, pledge, transfer or otherwise dispose of Sterling Common Stock
or Fleet Common Stock during the period commencing 30 days prior to the
Effective Time through the date on which financial results have been published
covering at least 30 days of combined operations of Fleet and Sterling after the
Merger. The restrictions in the preceding sentence do not apply to option
exercises by holders of options to purchase Sterling Common Stock under the
Sterling Stock Option Plan, or option exercises by holders of options to
purchase Fleet Common Stock received in the Merger if, in each case, the
exercise price and any required tax withholding payments are paid in the form of
cash, shares of Sterling Common Stock or Fleet Common Stock, as the case may be,
or through cash advances by brokers pursuant to a "cashless exercise"
arrangement.
    
 
   
DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN
    
 
   
     Fleet has an automatic Dividend Reinvestment and Stock Purchase Plan (the
"Plan"). Effective as of January 1, 1994, the Plan provides, in substance, for
those stockholders who elect to participate, that dividends on Fleet Common
Stock and optional cash payments of not less than $10 per month, up to a maximum
of $10,000 for each quarter, will be invested in shares of Fleet Common Stock.
The purchase price for Fleet Common Stock purchased with reinvested cash
dividends is 97% of the market price and for purchases with optional cash
payments is 100% of the market price. In each case, the Plan provides for the
payment by Fleet of any brokerage commissions or service charges with respect to
such purchases. After the Effective Time,
    
 
                                       43

<PAGE>   49
 
   
stockholders of Sterling who receive Fleet Common Stock in the Merger will have
the right to participate in the Plan. After the Effective Time, the Sterling DRP
will be terminated and shares therein after conversion to Fleet Common Stock
will be distributed pursuant to such plan, with cash to be paid in lieu of
fractional shares. The Plan is subject to amendment from time to time at Fleet's
discretion.
    
 
NO APPRAISAL RIGHTS
 
     Holders of Sterling Common Stock do not have any appraisal rights under
Delaware law in connection with the Merger.
 
          MATERIAL CONTRACTS BETWEEN AFFILIATES OF STERLING AND FLEET
 
     Affiliates of a director of the Bank and an affiliate of a director of
Sterling and the Bank have commercial lending relationships with affiliates of
Fleet, each of which was entered into in the ordinary course of business of such
Fleet affiliates.
 
                    INVOLVEMENT IN CERTAIN LEGAL PROCEEDINGS
 
     John A. Reeves, a current Director of Fleet, is an executive officer and
stockholder of Mid-Continent Minerals Corporation ("MCM"). One of MCM's
wholly-owned subsidiaries, Mid-continent Reserves, Inc., filed for
reorganization under Chapter 11 of the Federal Bankruptcy Code in 1993. A plan
under Chapter 11 is in the process of being approved.
 
                       CERTAIN REGULATORY CONSIDERATIONS
 
   
     General.  As a bank holding company, Fleet is subject to regulation by the
Federal Reserve Board. Fleet Bank of Maine ("Fleet-Maine"), Fleet Bank-NH, Fleet
Bank of New York and Fleet Bank are state-chartered banks that are members of
the Federal Reserve System; as such, they are subject to regulation by the
Federal Reserve Board and bank regulators in their respective states. Fleet
National Bank, Fleet-CT and the Surviving Bank are national banks subject to
regulation and supervision by the OCC. Each subsidiary bank's deposits are
insured by the FDIC and is therefore subject to FDIC supervision and regulation.
Fleet is also subject to the reporting and other requirements of the Exchange
Act.
    
 
   
     As a bank holding company, Sterling is regulated under the BHCA. Sterling
and the Bank's non-bank subsidiaries are subject to limitations on the scope of
their activities and to continuing regulation, supervision and examination by
the Federal Reserve Board under the BHCA and related federal statutes. As a
Delaware corporation, Sterling must comply with the general corporation law of
Delaware. As a Massachusetts-chartered, FDIC-insured savings bank, the Bank is
subject to regulation, examination and supervision by the FDIC. The Bank is also
subject to regulation and examination by the Commissioner of Banks of the
Commonwealth of Massachusetts.
    
 
     The general economic slowdown in the Northeast has combined with increased
regulatory scrutiny of financial institutions, generated in part by the thrift
crisis, to create a less certain economic and regulatory environment for all
financial institutions. In addition to Fleet's own monitoring activities, the
credit quality of the assets held by certain of Fleet's subsidiaries is subject
to periodic review by the state and federal bank regulatory agencies noted
above. While Fleet believes its present reserve for credit losses is adequate in
light of prevailing economic conditions and the current regulatory environment,
there can be no assurance that Fleet's subsidiaries will not be required to make
certain adjustments to their reserves for credit losses and charge-off policies
in response to changing economic conditions or regulatory examinations.
 
     Neither Fleet nor any of its subsidiaries has entered into formal written
agreements with state and federal regulators. At the request of its regulators,
Fleet and its subsidiaries continue to evaluate and refine oversight and
reporting systems and procedures to enhance the ability of such companies to
respond to the current negative economic environment.
 
                                       44
<PAGE>   50
 
   
     Payment of Dividends.  Fleet is a legal entity separate and distinct from
its subsidiaries. The ability of holders of debt and equity securities of Fleet,
including Sterling stockholders who will become holders of Fleet Common Stock
upon consummation of the Merger, to benefit from the distribution of assets of a
subsidiary upon the liquidation or reorganization of such subsidiary is
subordinate to prior claims of creditors of the subsidiary (including
depositors, in the case of banking subsidiaries) except to the extent that a
claim of Fleet as a creditor may be recognized.
    
 
     There are various statutory and regulatory limitations on the extent to
which banking subsidiaries of Fleet can finance or otherwise transfer funds to
Fleet or its nonbanking subsidiaries, whether in the form of loans, extensions
of credit, investments or asset purchases. Such transfers by any subsidiary bank
to Fleet or any nonbanking subsidiary are limited in amount to 10% of the bank's
capital and surplus and, with respect to Fleet and all such nonbanking
subsidiaries, to an aggregate of 20% of each such bank's capital and surplus.
Furthermore, loans and extensions of credit are required to be secured in
specified amounts and are required to be on terms and conditions consistent with
safe and sound banking practices. Under applicable banking statutes, at
September 30, 1993, Fleet's banking subsidiaries could have declared additional
dividends of approximately $382.3 million, of which $204.6 million could have
been declared by the Surviving Bank and Fleet-CT. Federal and state regulatory
agencies also have the authority to limit further Fleet's banking subsidiaries'
payment of dividends based on other factors, such as the maintenance of adequate
capital for such subsidiary bank. Further, holders of Fleet's Dual Convertible
Preferred Stock are entitled to dividends equal to one-half of the total
dividends declared (after the first $15 million in dividends) to Fleet, if any,
on the common stock of Fleet Banking Group.
 
     Under the policies of the Federal Reserve Board, Fleet is expected to act
as a source of financial strength to each subsidiary bank and to commit
resources to support such subsidiary bank in circumstances where it might not do
so absent such policy. In addition, any subordinated loans by Fleet to any of
the subsidiary banks would also be subordinate in right of payment to deposits
and obligations to general creditors of such subsidiary bank.
 
                     RECENT LEGISLATION AND RELATED MATTERS
 
     In addition to extensive existing government regulation, Federal and state
statutes and regulations are subject to changes that may have significant impact
on the way in which banks may conduct business. The likelihood and potential
effects of any such changes cannot be predicted. Legislation enacted in recent
years has substantially increased the level of competition among commercial
banks, thrift institutions and non-banking institutions, including insurance
companies, brokerage firms, mutual funds, investment banks and major retailers.
In addition, the enactment of recent banking legislation such as the Financial
Institutions Reform, Recovery and Enforcement Act ("FIRREA") and the FDICIA have
affected the banking industry by, among other things, broadening the regulatory
powers of the federal banking agencies in a number of areas. The following
summary is qualified in its entirety by the text of the relevant statutes and
regulations.
 
FIRREA
 
   
     As a result of the enactment of FIRREA on August 9, 1989, any or all of
Fleet's subsidiary banks can be held liable for any loss incurred by, or
reasonably expected to be incurred by, the FDIC after August 9, 1989, in
connection with (a) the default of any other of Fleet's subsidiary banks or (b)
any assistance provided by the FDIC to any other of Fleet's subsidiary banks in
danger of default. "Default" is defined generally as the appointment of a
conservator or receiver and "in danger of default" is defined generally as the
existence of certain conditions indicating that a "default" is likely to occur
without regulatory assistance.
    
 
FDICIA
 
     The FDICIA, which was enacted on December 19, 1991, provides for, among
other things, increased funding for the Bank Insurance Fund (the "BIF") of the
FDIC and expanded regulation of depository institutions and their affiliates,
including parent holding companies. A summary of certain provisions of FDICIA
and its implementing regulations is provided below.
 
                                       45
<PAGE>   51
 
   
     Risk Based Deposit Insurance Assessments.  A significant portion of the
additional funding to BIF is in the form of borrowings to be repaid by insurance
premiums assessed on BIF members. In addition, the FDICIA provides for an
increase in the ratio of the reserves to insured deposits of the BIF to 1.25% by
the end of the 15-year period that began with the semi-annual assessment period
ending December 31, 1991, also to be financed by insurance premiums. The result
of these provisions could be a significant increase in the assessment rate on
deposits of BIF members during the balance of this 15-year period. The FDICIA
also provides authority for special assessments against insured deposits and for
the development of a general risk-based assessment system. The FDIC has set
assessment rates for BIF-insured institutions ranging from 0.23% to 0.31%, based
on a risk assessment of the institution. Each financial institution is assigned
to one of three capital groups -- "well capitalized", "adequately capitalized"
or "undercapitalized" -- and further assigned to one of three subgroups within
each capital group, on the basis of supervisory evaluations by the institution's
primary federal and, if applicable, state supervisors and other information
relevant to the institution's financial condition and the risk posed to the
applicable insurance fund. For purposes of the risk-based assessment system, a
well-capitalized institution is one that has a total risk-based capital ratio of
10% or more, a Tier 1 risk-based capital of 6% or more, and a leverage ratio of
5% or more. An adequately capitalized institution has a total risk-based capital
ratio of 8% or more, a Tier 1 risk-based capital ratio of 4% or more, and a
leverage ratio of 4% or more. An undercapitalized institution is one that does
not meet either of the foregoing definitions. The actual assessment rate
applicable to a particular institution, therefore, depends in part upon the risk
assessment classification so assigned to the institution by the FDIC.
    
 
   
     Prompt Corrective Action.  The FDICIA also provides the federal banking
agencies with broad powers to take prompt corrective action to resolve problems
of insured depository institutions, depending upon a particular institution's
level of capital. The FDICIA establishes five tiers of capital measurement for
regulatory purposes ranging from "well-capitalized" to "critically
undercapitalized." Under prompt corrective action regulations adopted by the
federal banking agencies on September 29, 1992, a depository institution is (a)
"well-capitalized" if it has a total risk-based capital ratio of 10% or more, a
Tier 1 risk-based ratio of 6% or more, a leverage ratio of 5% or more and is not
subject to any written agreement, order or capital directive or prompt
corrective action directive issued by the primary regulator to meet and maintain
a specific capital measure; (b) "adequately capitalized" if it has a total
risk-based capital ratio of 8% or more, a Tier 1 risk-based capital ratio of 4%
or more and a leverage ratio of 4% or more (3% if the bank is rated composite 1
under the CAMEL rating system in its most recent examination and is not
experiencing or anticipating significant growth) and does not qualify as
"well-capitalized"; (c) "undercapitalized" if it has a total risk-based capital
ratio that is less than 8%, a Tier 1 risk-based capital ratio that is less than
4% or a leverage ratio that is less than 4% (3% if the bank is rated composite 1
under the CAMEL rating system in its most recent examination and is not
experiencing or anticipating significant growth); (d) "significantly
undercapitalized" if the bank has a total risk-based capital ratio that is less
than 6%, a Tier 1 risk-based capital ratio that is less than 3% or a leverage
ratio that is less than 3%; and (e) and "critically undercapitalized" if the
depository institution has a ratio of tangible equity to total assets that is
equal to or less than 2% of total assets, or otherwise fails to meet certain
established critical capital levels. A depository institution may be deemed to
be in a capitalization category that is lower than is indicated by its actual
capital position under certain circumstances. At September 30, 1993, each of
Fleet's subsidiary depository institutions was classified as either
"well-capitalized" or "adequately capitalized" under the prompt corrective
action regulations described above.
    
 
   
     Any depository institution that is undercapitalized and which fails to meet
regulatory capital requirements specified in the FDICIA must submit a capital
restoration plan guaranteed by the bank holding company controlling such
institution, and the regulatory agencies may place limits on the asset growth
and restrict activities of the institution (including transactions with
affiliates), require the institution to raise additional capital, dispose of
subsidiaries or assets or to be acquired and, ultimately, require the
appointment of a receiver. The guarantee of a controlling bank holding company
under the FDICIA of performance of a capital restoration plan is limited to the
lower of 5% of an undercapitalized banking subsidiary's assets or the amount
required for the bank to be classified as adequately capitalized. Federal
banking agencies may not accept a capital restoration plan without determining,
among other things, that the plan is based on realistic assumptions and is
likely to succeed in restoring the depository institution's capital. If a
depository institution
    
 
                                       46
<PAGE>   52
 
   
fails to submit an acceptable plan within the time required (generally 45 days
after receiving notice that the institution is undercapitalized, significantly
undercapitalized or critically undercapitalized), it is treated as if it is
significantly undercapitalized. If the controlling bank holding company fails to
fulfill its guaranty obligations under the FDICIA and files (or has filed
against it) a petition under the federal Bankruptcy Code, the applicable
regulatory agency would have a claim as a general creditor of the bank holding
company and, if the capital restoration plan were deemed to be a commitment to
maintain capital under the Federal Bankruptcy Code, the claim would be entitled
to a priority in such bankruptcy proceeding over unsecured third party creditors
of the bank holding company.
    
 
     In addition to the requirement of mandatory submission of a capital
restoration plan, under the FDICIA, an undercapitalized institution may not pay
management fees to any person having control of the institution nor may an
institution, except under certain circumstances and with prior regulatory
approval, make any capital distribution if, after making such payment or
distribution, the institution would be undercapitalized. Further, effective
December 19, 1993, undercapitalized depository institutions are subject to
restrictions on borrowing from the Federal Reserve System.
 
     Undercapitalized and significantly undercapitalized depository institutions
may be subject to a number of requirements and restrictions, including orders to
sell sufficient voting stock to become adequately capitalized, requirements to
reduce total assets and cessation of receipt of deposits from correspondent
banks. In addition, significantly undercapitalized depository institutions also
are prohibited from awarding bonuses or increasing compensation of senior
executive officers until approval of a capital restoration plan. Critically
undercapitalized depository institutions are subject to appointment of a
receiver or conservator.
 
   
     Brokered Deposits and Pass-Through Deposit Insurance Limitation.  Under the
FDICIA, a depository institution that is not well-capitalized is generally
prohibited from accepting brokered deposits and offering interest rates on
deposits "significantly higher" than the prevailing rate in its market. A
depository institution that is adequately capitalized may accept brokered
deposits if it obtains the prior approval of the FDIC. Effective in November
1993, the FDIC modified the definitions of "well-capitalized" and "adequately
capitalized" to conform to the definitions described above for prompt corrective
action. In addition, "pass-through" insurance coverage may not be available for
certain employee benefit accounts. In Fleet's opinion, these limitations do not
have a material effect on Fleet.
    
 
   
     Safety and Soundness Standards.  The FDICIA directs each federal banking
agency to prescribe safety and soundness standards for depository institutions
and depository institution holding companies relating to internal controls,
information systems, internal audit systems, loan documentation, credit
underwriting, interest rate exposure, asset growth, compensation, a maximum
ratio of classified assets to capital, minimum earnings sufficient to absorb
losses without impairing capital, a minimum ratio of market value to book value
for publicly traded shares and such other standards as the agency deems
appropriate. Proposed regulations to implement the safety and soundness
standards were issued in November 1993. The ultimate cumulative effect of these
standards cannot currently be forecast.
    
 
     The FDICIA also contains a variety of other provisions that may affect
Fleet's and Sterling's respective operations, including new reporting
requirements, regulatory standards for real estate lending, "truth in savings"
provisions, and the requirement that a depository institution give 90 days'
prior notice to customers and regulatory authorities before closing any branch.
Many of the provisions in the FDICIA have recently been or will be implemented
through the adoption of regulations by the various federal banking agencies and,
therefore, the precise impact on Fleet cannot be assessed at this time.
 
   
     Capital Guidelines.  In January 1989, the Federal Reserve Board issued
final risk-based capital guidelines for bank holding companies such as Fleet and
state-chartered member banks. The new regulatory minimum capital requirements,
which became effective in March 1989, have been phased in over the past four
years. Under the requirements as fully phased in, the minimum ratio of total
capital to risk-adjusted assets (including certain off-balance sheet items, such
as standby letters of credit) is 8%. At least half of the total capital is to be
comprised of common equity, retained earnings, minority interests in the equity
accounts of consolidated subsidiaries and a limited amount of perpetual
preferred stock, less goodwill ("Tier 1 capital"). The remainder may consist of
perpetual debt, mandatory convertible debt securities, a limited amount of
    
 
                                       47
<PAGE>   53
 
   
subordinated debt, other preferred stock and a limited amount of loan loss
reserves (supplementary capital). In addition, on August 2, 1990, the Federal
Reserve Board adopted a leverage ratio (Tier 1 capital to total assets, net of
goodwill) of 3% for bank holding companies that meet certain specified criteria,
including that they have the highest regulatory rating. The rule indicates that
the minimum leverage ratio should be 1% to 2% higher for holding companies
undertaking major expansion programs or that do not have the highest regulatory
rating. Fleet's national banking subsidiaries, including the Surviving Bank, are
subject to similar capital requirements adopted by the OCC.
    
 
   
     As of September 30, 1993, Fleet's and Sterling's capital ratios on a
historical basis exceeded all minimum regulatory capital requirements.
     
     Under FIRREA and the FDICIA, failure to meet the minimum regulatory capital
requirements could subject a banking institution to a variety of enforcement
remedies available to federal regulatory authorities, including the termination
of deposit insurance by the FDIC and seizure of the institution.
 
   
                              RECENT DEVELOPMENTS
    
   
1993 FOURTH QUARTER AND YEAR END RESULTS
    
 
   
     Fleet.  Fleet's net income for the quarter ended December 31, 1993, was
$136.0 million, or $0.85 per fully diluted share, compared to net income of
$82.3 million, or $0.52 per fully diluted share for the fourth quarter of 1992.
Net income for the year ended December 31, 1993 was $488.0 million, or $3.01 per
fully diluted share, compared to net income in 1992 of $279.8 million, or $1.77
per fully diluted share.
     
   
     Included in results for the year ended December 31, 1993 were a $125
million restructuring charge relating to Fleet's efficiency improvement program,
"Fleet Focus '94", a $135 million charge at Fleet Mortgage Group, Inc. ("FMG"),
an 81% owned subsidiary of Fleet, related to the accelerated amortization of
mortgage servicing assets, and $282 million of securities gains.
    
   
     Net interest income for the fourth quarter and for the year ended December
31, 1993 totaled $514 million and $2.1 billion, respectively, compared to $506
million and $2.0 billion for the comparable periods in the previous year. The
net interest margin for the fourth quarter was 4.91%, compared to 5.08% for the
third quarter of 1993. The net interest margin for the year ended December 31,
1993 was 5.02%, compared to 4.80% for the previous year.
    
   
     Noninterest income for the year ended December 31, 1993 was $1.5 billion,
compared to $1.4 billion for the prior year.
    
   
     Noninterest expense for the year ended December 31, 1993 increased to $2.4
billion from the $2.3 billion reported for 1992, reflecting, in 1993, the $125
million restructuring charge and the $135 million charge at FMG related to the
accelerated amortization of mortgage servicing assets, and in 1992, the loss on
the sale of problem assets of $115 million, and the $25 million charge related
to the Fleet Finance, Inc. 10-point program.
     
   
     Fleet's provision for credit losses was $55 million in the fourth quarter
of 1993, a decrease of $5 million from the third quarter of 1993. Such
provisions for the year ended December 31, 1993 also decreased to $271 million,
compared to $486 million at December 31, 1992.
     
   
     As of December 31, 1993, nonperforming assets were $601 million, compared
to $736 million at September 30, 1993, and $990 million at December 31, 1992.
Such decrease was primarily due to improvement of credit quality of Fleet's
assets.
     
   
     Fleet's reserve for credit losses decreased $29 million from December 31,
1992 to December 31, 1993, as loans and leases charged off during the year
exceeded the amount of the provision and recoveries recognized during the year.
At December 31, 1993, Fleet's ratio of reserves to nonperforming loans was 215%,
compared to 137% at December 31, 1992.
    
 
                                       48
<PAGE>   54
 
   
     At December 31, 1993, Fleet had total assets of $47.9 billion, total
deposits of $31.1 billion and total stockholders' equity of $3.6 billion. At
December 31, 1993, Fleet's capital ratios exceeded all minimum regulatory
capital requirements.
    
 
   
     Sterling.  On January 20, 1994, Sterling reported net income for the three
months ended December 31, 1993 of $260,000, or $0.08 per share on a fully
diluted basis, compared to net income of $1.9 million, or $0.63 per share, for
the comparable period of 1992. Net income for the three months ended December
31, 1993 was adversely affected by a one-time charge of $3.3 million relating to
the proposed Merger. For the year ended December 31, 1993, net income was $6.2
million, or $1.98 per share on a fully diluted basis. Net income for the year
ended December 31, 1992 was $7.9 million, or $2.60 per share, which included a
one-time $1.1 million or $0.36 per share gain realized during the first quarter
of 1992 in connection with the adoption of Statement of Financial Accounting
Standards No. 109 (SFAS No. 109) "Accounting for Income Taxes".
    
 
   
     At December 31, 1993, nonperforming assets were $3.6 million or 0.35% of
total assets, consisting of $1.8 million in nonperforming loans and $1.8 million
in other real estate owned, net. This compares with nonperforming assets of $7.6
million at December 31, 1992 and $4.5 million at September 30, 1993. During the
fourth quarter of 1993, Sterling added $450,000 to its reserve for loan losses,
bringing its total loan loss reserve to $7.2 million. This level of loan loss
reserve represented 401% of nonperforming loans and 201% of nonperforming assets
at December 31, 1993. Total assets at December 31, 1993 were $1.0 billion,
comprised primarily of $457.6 million in net loans and $535.3 million in
investments. Total deposits were $624.6 million at December 31, 1993, compared
to $672.9 million at December 31, 1992.
    
 
   
     At December 31, 1993 Sterling adopted Statement of Financial Accounting
Standards No. 115 (SFAS 115), "Accounting for Certain Investments In Debt and
Equity Securities". On an after tax basis, at that date, there were $6.6 million
in unrealized gains related to $411.6 million of investments which Sterling
classified as available for sale. Accordingly, these unrealized gains are
included as a separate component of stockholders' equity.
    
 
   
     At December 31, 1993, Sterling had 3,045,031 shares of common stock
outstanding, and a net book value of $21.29 per share, excluding the effect of
SFAS 115. On January 19, 1994, Sterling's Board of Directors declared a cash
dividend of $0.18 per share, payable on February 11, 1994 to all shareholders of
record as of January 31, 1994.

     The following summary does not purport to be complete and is subject in all
respects to the applicable provisions of the Rhode Island Business Corporation
Act ("Rhode Island law") and the Fleet Restated Articles and Fleet By-Laws.
 
FLEET COMMON STOCK
 
   
     General.  Holders of the Fleet Common Stock are entitled to receive
dividends when, as and if declared by the Board of Directors out of any funds
legally available therefor, and are entitled upon liquidation, after claims of
creditors and preferences of the Preferred Stock, and any other series of
preferred stock at the time outstanding, to receive pro rata the net assets of
Fleet. Dividends are paid on the Fleet Common Stock only if all dividends on the
outstanding classes or series of Preferred Stock for the then-current period
and, in the case of cumulative Preferred Stock, all prior periods have been paid
or provided for.
    
 
     Fleet $1 Par Preferred Stock and any other class of preferred stock
(including Fleet $20 Par Adjustable Rate Preferred Stock) have, or upon issuance
will have, preference over the Fleet Common Stock with respect to the payment of
dividends and the distribution of assets in the event of liquidation or
dissolution of Fleet and such other preferences as may be fixed by the Board of
Directors.
 
     The holders of the Fleet Common Stock are entitled to one vote for each
share held and are vested with all of the voting power except as the Board of
Directors has provided with respect to the Preferred Stock or may provide, in
the future, with respect to any other series of preferred stock which it may
hereafter authorize. See "-- Preferred Stock". Shares of Fleet Common Stock are
not redeemable and have no subscription, conversion or preemptive rights.
 
     The affirmative vote of not less than 80% of Fleet's outstanding voting
stock, voting separately as a class, is required for certain Business
Combinations between Fleet and/or its subsidiaries and persons owning 10% or
more of its voting stock. See "-- Selected Provisions in the Restated Articles
of Fleet; Business Combinations with Related Persons".
 
     The Fleet Common Stock is listed on the Stock Exchange. The outstanding
shares of Fleet Common Stock are, and the shares to be issued to Sterling
stockholders upon consummation of the Merger will be, validly issued, fully paid
and non-assessable and the holders thereof are not, and will not be, subject to
any liability as stockholders.

     Restrictions on Ownership.  The BHCA requires any "bank holding company",
as such term is defined therein, to obtain the approval of the Federal Reserve
Board prior to the acquisition of 5% or more of the Fleet Common Stock. Any
person other than a bank holding company is required to obtain prior approval of
the Federal Reserve Board to acquire 10% or more of the Fleet Common Stock under
the Change in Bank Control Act (the "CBCA"). The partnerships which purchased
the Dual Convertible Preferred Stock (the "Partnerships") made a filing under
the CBCA because of their acquisition of such stock. Any holder of 25% or more
of the Fleet Common Stock (or a holder of 5% or more if such holder otherwise
exercises a "controlling influence" over Fleet) is subject to regulation as a
bank holding company under the BHCA.
    
 
   
     Preferred Share Purchase Rights.  On November 21, 1990, the Board of
Directors of Fleet declared a dividend of one preferred share purchase right
("Right") for each outstanding share of Fleet Common Stock. The dividend was
paid on December 4, 1990 to the shareholders of record on that date. Each Right,
when exercisable, will entitle the registered holder to purchase from Fleet one
one-hundredth of a share of the Junior Preferred Stock of Fleet, at an exercise
price of $50 per one one-hundredth of a share of Junior Preferred Stock (the
"Purchase Price"), subject to certain adjustments. Until the earlier to occur of
the Distribution Date and the Expiration Date (each as hereinafter defined),
Fleet will issue one Right with each share of Fleet Common Stock; accordingly,
each stockholder of Sterling who receives Fleet Common Stock upon consummation
of the Merger shall automatically receive one Right with each such share issued.
The following summary does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all of the provisions of the Rights
Agreement dated as of November 21, 1990 between Fleet and Fleet National Bank,
as Rights Agent, a copy of which was filed as an exhibit to the Registration
Statement on Form 8-A dated November 29, 1990, as amended by a First Amendment
to Rights Agreement dated March 28, 1991 and a Second Amendment to Rights
Agreement dated July 12, 1991, copies of which were filed as exhibits to Fleet's
Amendment to Application or Report on Form 8 dated September 6, 1991 (as
amended, the "Rights Agreement").
    
 
   
     The Rights are not represented by separate certificates and are not
exercisable or transferable apart from the Fleet Common Stock until the earlier
to occur of (i) the tenth day after a public announcement by Fleet (x) that a
person or group of affiliated or associated persons has, subsequent to November
21, 1990 (the "Declaration Date") acquired, or obtained the right to acquire,
beneficial ownership (as defined in the Rights Agreement) of 10% or more (or, in
the case of a qualifying institutional investor, acting in the ordinary course
of business and not with the purpose of changing or influencing control of Fleet
(a "Qualifying Investor"), 15% or more) of the outstanding shares of Fleet
Common Stock, (y) that any person or group of affiliated or associated persons,
which beneficially owned 10% or more (or, in the case of a Qualifying Investor,
15% or more) of the outstanding shares on the Declaration Date, or which
acquired beneficial ownership of 10% or more (or, in the case of a Qualifying
Investor, 15% or more) of the outstanding shares as a result of any repurchase
of shares by Fleet, thereafter acquired beneficial ownership of additional
shares constituting 1% or more of the outstanding shares, or (z) that any person
who was a Qualifying Investor owning 10% or more of the outstanding shares of
Fleet Common Stock ceased to qualify as a Qualifying Investor and thereafter
acquired beneficial ownership of additional shares constituting 1% or more of
the outstanding shares (any person described in clause (x), (y) or (z) being an
"Acquiring Person"); and (ii) the tenth day (or such later day as may be
determined by action of the Board of Directors of Fleet prior to such time as
any person becomes an Acquiring Person) after the date of the commencement of a
tender or exchange offer by any person (other than Fleet) to acquire (when added
to any shares as to which such person is the beneficial owner immediately prior
to such commencement) beneficial ownership of 10% or more of the issued and
outstanding shares of Fleet Common Stock (the earlier of such dates being called
the "Distribution Date"). On March 28, 1991 and July 12, 1991 the Rights
Agreement was amended to change the definition of an "Acquiring Person" (i) to
permit the sale of the Dual Convertible Preferred Stock and issuance of rights
to purchase Fleet Common Stock to the Partnerships and (ii) to permit the Board
of Directors of Fleet to determine that a person who would otherwise be an
"Acquiring Person" had become such inadvertently and therefore allow divestiture
of a sufficient number of shares to avoid such designation.
    
 
     The Rights will first become exercisable on the Distribution Date and could
then begin trading separately from the Fleet Common Stock. The Rights will
expire on the earliest of November 21, 2000 (the "Final
 
                                       51
<PAGE>   57
 
Expiration Date"), the date on which the Rights are earlier redeemed by Fleet or
the date on which the Rights are exchanged (such earliest date being referred to
as the "Expiration Date").
 
     In the event any person becomes an Acquiring Person, the Rights would give
holders (other than such Acquiring Person and its transferees) the right to buy,
for the Purchase Price (and in lieu of Junior Preferred Stock), Fleet Common
Stock (or, under certain circumstances, cash, property or other debt or equity
securities ("Fleet Common Stock equivalents")) with a market value of twice the
Purchase Price. In addition, at any time after any person becomes an Acquiring
Person, the Board may, at its option and in lieu of any transaction described in
the preceding sentence, exchange the outstanding and exercisable Rights (other
than Rights held by any such Acquiring Person and its transferees) for shares of
Fleet Common Stock or Fleet Common Stock equivalents at an exchange ratio of one
share of Fleet Common Stock per Right, subject to certain adjustments.
 
     In any merger or consolidation involving Fleet after the Rights become
exercisable, each Right will be converted into the right to purchase, for the
Purchase Price, common stock of the surviving corporation (which may be Fleet)
with a market value of twice the Purchase Price.
 
   
     The Board of Directors of Fleet may amend the Rights Agreement or redeem
the Rights for $.01 each at any time until the date of a public announcement by
Fleet that there is an Acquiring Person. Thereafter, the Board of Directors may
amend the Rights Agreement only to eliminate ambiguities or to provide
additional benefits to, and if the amendment would not adversely affect, the
holders of the Rights (other than the Acquiring Person).
    
 
     Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of Fleet, including, without limitation, the right to
vote or to receive dividends.
 
     The Purchase Price payable, and the number of shares of Junior Preferred
Stock or other securities or property issuable, upon exercise of the Rights, and
the number of outstanding Rights, are subject to customary antidilution
adjustments.
 
     The Rights have certain "anti-takeover" effects. The Rights may cause
substantial dilution to a person or group that attempts to acquire Fleet on
terms not approved by the Board of Directors of Fleet, except pursuant to an
offer conditioned on a substantial number of Rights being acquired. The Rights
should not interfere with any merger or other business combination approved by
the Board of Directors prior to the time that there is an Acquiring Person (at
which time holders of the Rights become entitled to exercise their Rights for
shares of Fleet Common Stock at one-half the market price), since until such
time the Rights generally may be redeemed by the Board of Directors of Fleet at
$.01 per Right.
 
   
     Transfer Agent and Registrar.  The Transfer Agents for the Fleet Common
Stock are Fleet National Bank, Providence and Mellon Securities Transfer
Services, Inc., New York, and the Registrars are Citizens Trust Company,
Providence and Chemical Bank, New York.
    
 
PREFERRED STOCK
 
   
FLEET $1 PAR PREFERRED STOCK
    
 
     Fleet $1 Par Preferred Stock is issuable in series, with such relative
rights, preferences and limitations of each series (including dividend rights,
dividend rate, liquidation preference, voting rights, conversion rights and term
of redemption (including sinking fund provisions), redemption price or prices
and the number of shares constituting any series) as may be fixed by the Board
of Directors of Fleet.
 
   
     As of the date of this Proxy Statement-Prospectus, Fleet has four series of
Fleet $1 Par Preferred Stock outstanding.
    
 
   
     Fleet $1 Par Adjustable Rate Preferred Stock.  In the event of dissolution,
liquidation or winding up of Fleet, the holders of shares of the outstanding
Fleet $1 Par Adjustable Rate Preferred Stock are entitled to receive a
distribution of $50 per share, plus accrued and unpaid dividends, if any. The
Fleet $1 Par Adjustable
    
 
                                       52
<PAGE>   58
 
Rate Preferred Stock is redeemable, in whole or in part, at Fleet's option, at
the stated value of $50 per share, plus, in each case, accrued and unpaid
dividends, if any.
 
   
     The dividend rate on the Fleet $1 Par Adjustable Rate Preferred Stock is
paid on the basis of an issue price of $50 per share, payable quarterly, and is
reset quarterly at a rate per annum of 3.25% below the highest of (a) the
three-month U.S. Treasury bill rate; (b) the U.S. Treasury ten-year constant
maturity rate; or (c) the U.S. Treasury twenty-year constant maturity rate, all
as shall be in effect at the time of determination. In no event will such rate
be less than 6% per annum or more than 12% per annum. Dividends on the
outstanding Fleet $1 Par Adjustable Rate Preferred Stock are cumulative.
    
 
   
     Other than as hereinafter set forth and as required by Rhode Island law,
holders of the Fleet $1 Par Adjustable Rate Preferred Stock have no voting
rights. The approval of 66 2/3% of the outstanding shares of the Fleet $1 Par
Adjustable Rate Preferred Stock is required to authorize an amendment to the
Fleet Restated Articles which would have an adverse effect on such stock. The
affirmative vote or consent of the holders of at least 66 2/3% of the
outstanding shares of the Fleet $1 Par Adjustable Rate Preferred Stock and any
other series of Fleet $1 Par Preferred Stock ranking on a parity with the Fleet
$1 Par Adjustable Rate Preferred Stock either as to dividends or upon
liquidation, voting as a single class without regard to series, is required to
issue or authorize any additional class or series ranking prior to the Fleet $1
Par Adjustable Rate Preferred Stock as to dividends or upon liquidation, or
issue or authorize any obligation or security convertible into or evidencing a
right to purchase such prior shares or to reclassify any authorized stock of
Fleet into such prior shares. In addition, in the event that the equivalent of
six quarterly dividends payable on the Fleet $1 Par Adjustable Rate Preferred
Stock are in default, the number of directors of Fleet will be increased by two
(without duplication of any increase made pursuant to the terms of any other
series of preferred stock of Fleet), and the holders of all outstanding shares
of Fleet $1 Par Adjustable Rate Preferred Stock shall have the exclusive right,
voting as a class with the holders of all other series and classes of preferred
stock similarly entitled to vote, to elect such two additional directors until
all past due dividends have been paid or provided for.
    
 
   
     Series I Preferred.  All outstanding shares of Series I Preferred were
converted into Fleet Common Stock effective October 1, 1993.
 
     Series II Preferred.  The Series II Preferred was convertible by the
holders thereof into Fleet Common Stock at any time, and redeemable by Fleet at
any time. All outstanding shares of Series II Preferred were called for
redemption by Fleet on September 29, 1993. Upon receipt of the notice of
redemption, each holder opted to convert its Series II Preferred into Fleet
Common Stock prior to September 29, 1993.
 
     Series III Preferred.  In the event of the dissolution, liquidation or
winding up of Fleet, holders of shares of the outstanding Series III Preferred
are entitled to receive a distribution of $100 per share, plus accrued and
unpaid dividends, if any.
 
     The holders of Series III Preferred are entitled to receive dividends at
the rate of 10.12% per annum computed on the basis of the issue price thereof of
$100 per share, payable quarterly, before any dividend shall be declared or paid
upon the Fleet Common Stock or the Junior Preferred Stock. The dividends on
Series III Preferred are cumulative. The Series III Preferred is redeemable, in
whole or in part, at Fleet's option, on and after June 1, 1996, commencing at
$105.06 per share and declining ratably on June 1 of each year to $100 per share
on or after June 1, 2001, plus, in each case, accrued and unpaid dividends, if
any.
 
     Except as indicated below or except as expressly required by applicable
law, the holders of the Series III Preferred are not entitled to vote. If the
equivalent of six quarterly dividends payable on the Series III Preferred or any
other class or series of preferred stock (other than any other class of
preferred stock expressly entitled to elect additional directors by a separate
and distinct vote) are in default, the number of directors of Fleet will be
increased by two (without duplication of any increase made pursuant to the terms
of any other series of preferred stock of Fleet), and the holders of the Series
III Preferred, voting as a single class with the holders of shares of any one or
more other series of Fleet $1 Par Preferred Stock (other than any other class of
preferred stock expressly entitled to elect additional directors by a separate
and distinct vote) and any other class of Fleet preferred stock ranking on a
parity with the Series III Preferred either as to dividends or distribution of
assets and upon which like voting rights have been conferred and are
exercisable, will be
    
 
                                       53
<PAGE>   59
 
   
entitled to elect two directors to fill each of the two newly-created
directorships. Such right shall continue until full cumulative dividends for all
past dividend periods on all preferred shares of Fleet (other than any other
class of preferred stock expressly entitled to elect additional directors by a
separate and distinct vote), including any shares of the Series III Preferred,
have been paid or declared and set apart for payment. Any such elected directors
shall serve until Fleet's next annual meeting of stockholders (notwithstanding
that prior to the end of such term the dividend default shall cease to exist) or
until their respective successors shall be elected and qualify.
    
 
   
     The affirmative vote or consent of the holders of at least 66 2/3% of the
outstanding shares of the Series III Preferred is required for any amendment of
the Fleet Restated Articles (or any certificate supplemental thereto) which will
adversely affect the powers, preferences, privileges or rights of the Series III
Preferred. The affirmative vote or consent of the holders of at least 66 2/3% of
the outstanding shares of the Series III Preferred and any other series of Fleet
$1 Par Preferred Stock ranking on a parity with the Series III Preferred either
as to dividends or upon liquidation, voting as a single class without regard to
series, is required to issue, authorize or increase the authorized amount of, or
issue or authorize any obligation or security convertible into or evidencing a
right to purchase, any additional class or series of stock ranking prior to the
Series III Preferred as to dividends or upon liquidation, or to reclassify any
authorized stock of Fleet into such prior shares.
    
 
   
     Series IV Preferred.  In the event of the dissolution, liquidation or
winding up of Fleet, holders of shares of the outstanding Series IV Preferred
are entitled to receive a distribution of $100 per share, plus accrued and
unpaid dividends, if any.
    
 
     The holders of Series IV Preferred are entitled to receive dividends at the
rate of 9.375% per annum computed on the basis of the issue price thereof of
$100 per share, payable quarterly, before any dividend shall be declared or paid
upon the Fleet Common Stock or the Junior Preferred Stock. The dividends on
Series IV Preferred are cumulative. The Series IV Preferred is redeemable, in
whole or in part, at Fleet's option, on and after December 1, 1996, at $100 per
share, plus accrued and unpaid dividends, if any.
 
   
     Except as indicated below or except as expressly required by applicable
law, the holders of the Series IV Preferred are not entitled to vote. If the
equivalent of six quarterly dividends payable on the Series IV Preferred or any
other class or series of preferred stock are in default (other than any other
class of preferred stock expressly entitled to elect additional directors by a
separate and distinct vote), the number of directors of Fleet will be increased
by two (without duplication of any increase made pursuant to the terms of any
other series of preferred stock of Fleet), and the holders of the Series IV
Preferred, voting as a single class with the holders of shares of any one or
more other series of Fleet $1 Par Preferred Stock (other than any other class of
preferred stock expressly entitled to elect additional directors by a separate
and distinct vote) and any other class of Fleet preferred stock ranking on a
parity with the Series IV Preferred either as to dividends or distribution of
assets and upon which like voting rights have been conferred and are
exercisable, will be entitled to elect such directors to fill each of the two
newly-created directorships. Such right shall continue until full cumulative
dividends for all past dividend periods on all preferred shares of Fleet (other
than any other class of preferred stock expressly entitled to elect additional
directors by a separate and distinct vote), including any shares of the Series
IV Preferred, have been paid or declared and set apart for payment. Any such
elected directors shall serve until Fleet's next annual meeting of stockholders
(notwithstanding that prior to the end of such term the dividend default shall
cease to exist) or until their respective successors shall be elected and
qualify.
    
 
     The affirmative vote or consent of the holders of at least 66 2/3% of the
outstanding shares of the Series IV Preferred is required for any amendment of
the Fleet Restated Articles (or any certificate supplemental thereto) which will
adversely affect the powers, preferences, privileges or rights of the Series IV
Preferred. The affirmative vote or consent of the holders of at least 66 2/3% of
the outstanding shares of the Series IV Preferred and any other series of Fleet
$1 Par Preferred Stock ranking on a parity with the Series IV Preferred either
as to dividends or upon liquidation, voting as a single class without regard to
series, is required to issue, authorize or increase the authorized amount of, or
issue or authorize any obligation or security convertible into or evidencing a
right to purchase, any additional class or series of stock ranking prior to the
Series IV
 
                                       54

Preferred as to dividends or upon liquidation, or to reclassify any authorized
stock of Fleet into such prior shares.
    
 
   
     Dual Convertible Preferred Stock.  The Dual Convertible Preferred Stock has
no voting rights except as provided by Rhode Island law or as indicated below.
The Dual Convertible Preferred Stock is not entitled to vote for the election of
directors in any circumstances, including dividend arrearages, and the holders
thereof have agreed to vote the Dual Convertible Preferred Stock as directed by
Fleet's board of directors on any matters upon which the shares are entitled to
vote under Rhode Island law, except on those matters adversely affecting the
rights of holders of Dual Convertible Preferred Stock. The affirmative vote or
consent of the holders of at least 66 2/3% of the outstanding shares of Dual
Convertible Preferred Stock, voting as a class, given in person or by proxy,
either in writing or by resolution adopted at a special meeting called for the
purpose, is required to authorize any new class of equity securities of Fleet to
which the Dual Convertible Preferred Stock ranks junior, whether with respect to
dividends or upon liquidation, dissolution, winding up or otherwise. In
addition, the affirmative vote or consent of the holders of at least 66 2/3% of
the outstanding shares of Dual Convertible Preferred Stock, voting as a class,
given in person or by proxy, either in writing or by resolution adopted at a
special meeting called for the purpose, shall be required for any amendment of
Fleet's Restated Articles (or the certificate of designation of the Dual
Convertible Preferred Stock), which would affect materially and adversely the
specified rights, preferences, privileges or voting rights of shares of Dual
Convertible Preferred Stock.
    
 
   
     The holders of Dual Convertible Preferred Stock are entitled to dividends
equal to one-half of the total dividends declared (after the first $15 million
in dividends), if any, by Fleet Banking Group on its common stock. Such
dividends, if accrued and unpaid, will be cumulative. In the event of the
liquidation, dissolution or winding up of Fleet, the holders of the outstanding
Dual Convertible Preferred Stock are entitled to receive a distribution of $200
per share, plus accrued and unpaid dividends, if any.
    
 
   
     On July 31, 1991, the date of issuance of the Dual Convertible Preferred
Stock, Fleet granted to the Partnerships which purchased the Dual Convertible
Preferred Stock rights (the "DCP Rights") to purchase 6,500,000 shares of Fleet
Common Stock at $17.65 per share.
    
 
   
     The Dual Convertible Preferred Stock is convertible into Fleet Common Stock
at a conversion price of $17.65 per share at any time. The total number of
shares issuable upon such conversion is 16,033,994 shares, subject to customary
anti-dilution adjustments. If any of such stock is converted prior to July 12,
2001, all of such stock must be converted. After July 12, 2001, any holder of
Dual Convertible Preferred Stock may convert its stock into Fleet Common Stock
independently of any other holder.
    
 
   
     The Dual Convertible Preferred Stock is also convertible into 50% of the
common stock of Fleet Banking Group at any time after the later of (i) July 12,
1995 and (ii) the date on which the Partnerships distribute all the shares of
Dual Convertible Preferred Stock then held by them to the partners therein
(which distribution date will be July 12, 1997 unless the Federal Reserve Board
consents to an alternative distribution date, but in no event earlier than July
12, 1995). The Dual Convertible Preferred Stock is also convertible into Fleet
Banking Group common stock on an earlier date in the event that the quotient of
(i) Fleet's Tier 1 capital as of the date of determination (adjusted to include
goodwill of Fleet as of July 12, 1991) divided by (ii) total assets, falls below
3%. The Dual Convertible Preferred Stock is not convertible into Fleet Banking
Group common stock after July 12, 2001 or at any time while it is held by the
Partnerships. After the Dual Convertible Preferred Stock becomes convertible
into Fleet Banking Group common stock, the holders of the Dual Convertible
Preferred Stock will have the right to obtain an appraisal of the fair value of
the common stock of Fleet Banking Group (the "Appraisal") as if all such shares
were to be sold to a third party in a transaction reflecting a control premium.
If such Appraisal is acceptable to the holders of the Dual Convertible Preferred
Stock, the Dual Convertible Preferred Stock may be converted into 50% of the
common stock of Fleet Banking Group on or after the date that is six months
after such acceptance or, in the case of the earlier date due to the capital
deficiency described above, on or after the date that is 60 days after the
notice of such deficiency. During the period after acceptance but prior to the
date on which such shares become convertible, Fleet will have the option to
redeem the Dual Convertible Preferred Stock at a redemption price equal to 50%
of the Appraisal price less the sum of (i) the market value of the shares of
Fleet Common Stock
    
 
                                       55
<PAGE>   61
 
   
into which the Dual Convertible Preferred Stock are then convertible (and such
shares of Fleet Common Stock shall be distributed to the holders of Dual
Convertible Preferred Stock) and (ii) the value of the DCP Rights. Fleet has the
option to pay such redemption price in cash or in any combination of Fleet
securities having a realizable market value equal to such redemption price. If
Fleet does not exercise this option, the holders of the Dual Convertible
Preferred Stock may convert their shares into 50% of the common stock of Fleet
Banking Group. Any such conversion must be for all of the Dual Convertible
Preferred Stock.
    
 
   
     Junior Preferred Stock.  The Junior Preferred Stock will be issued upon the
exercise of a Right issued to holders of the Fleet Common Stock. As of the date
of this Prospectus, there were 1,500,000 shares of Fleet $1 Par Preferred Stock
reserved for issuance upon the exercise of the Rights. See "-- Common Stock --
Preferred Share Purchase Rights". Shares of Junior Preferred Stock purchasable
upon exercise of the Rights will rank junior to the Fleet $1 Par Preferred Stock
and the Fleet $20 Par Adjustable Rate Preferred Stock and will not be
redeemable. Each share of Junior Preferred Stock will, subject to the rights of
such senior securities of Fleet, be entitled to a preferential cumulative
quarterly dividend payment equal to the greater of $1.00 per share or, subject
to certain adjustments, 100 times the dividend declared per share of Fleet
Common Stock. Upon the liquidation, dissolution or winding up of Fleet, the
holders of the Junior Preferred Stock will, subject to the rights of such senior
securities, be entitled to a preferential liquidation payment equal to the
greater of $100 per share plus all accrued and unpaid dividends or 100 times the
payment made per share of Fleet Common Stock. Finally, in the event of any
merger, consolidation or other transaction in which shares of Fleet Common Stock
are exchanged, each share of Junior Preferred Stock will, subject to the rights
of such senior securities, be entitled to receive 100 times the amount received
per share of Fleet Common Stock. Each share of Junior Preferred Stock will have
100 votes, voting together with the Fleet Common Stock and the Series I
Preferred. The rights of the Junior Preferred Stock are protected by customary
antidilution provisions.
    
 
   
FLEET $20 PAR ADJUSTABLE RATE PREFERRED STOCK
    
 
     The Fleet $20 Par Adjustable Rate Preferred Stock is a separate class of
preferred stock of Fleet, and entitled, in the event of the liquidation,
dissolution or winding up of Fleet, to receive a distribution of $50 per share,
plus accrued and unpaid dividends, if any. The Fleet $20 Par Adjustable Rate
Preferred Stock is redeemable at Fleet's option, in whole or in part, at the
stated value of $50 per share, plus, in each case, accrued and unpaid dividends.
 
   
     The dividend rate on the Fleet $20 Par Adjustable Rate Preferred Stock is
paid on the basis of an issue price of $50 per share, payable quarterly, and is
reset quarterly at a rate of 3.00% per annum below the highest of (a) the
three-month U.S. Treasury bill rate; (b) the U.S. Treasury ten-year constant
maturity rate; or (c) the U.S. Treasury twenty-year constant maturity rate, all
as shall be in effect at the time of determination. In no event will such rate
be less than 6% per annum or more than 13% per annum. Dividends on the
outstanding Fleet $20 Par Adjustable Rate Preferred Stock are cumulative.
    
 
     Other than as hereinafter set forth and as required by Rhode Island law,
holders of the Fleet $20 Par Adjustable Rate Preferred Stock have no voting
rights. The approval of 66 2/3% of the outstanding shares of the Fleet $20 Par
Adjustable Rate Preferred Stock is required if an amendment to the Fleet
Restated Articles or a corporate transaction, such as a merger or consolidation,
sale of assets or other disposition, contains any provision which would have the
effect of limiting or denying the voting rights of such stock, reducing its par
value, changing the number of shares of such stock into a different number or
class, changing the designation or relative rights of such class or otherwise
subordinating the rights of such stock. In addition, in the event that the
equivalent of six quarterly dividends are in default on the outstanding Fleet
$20 Par Adjustable Rate Preferred Stock, the number of directors of Fleet will
be increased by two (without duplication of any increase made pursuant to the
terms of any other series of preferred stock of Fleet), and the holders of all
outstanding Fleet $20 Par Adjustable Rate Preferred Stock shall have the
exclusive right, voting as a class with the holders of any other class or series
of preferred stock which is not otherwise entitled to vote upon the election of
directors, to elect such two additional directors until all dividends in default
have been paid or provided for.

SELECTED PROVISIONS IN THE FLEET RESTATED ARTICLES
 
   
     Business Combinations with Related Persons.  The Fleet Restated Articles
require that neither Fleet nor any of its subsidiaries may engage in a Business
Combination with a Related Person unless such Business Combination (a) was
approved by an 80% vote of the Board of Directors prior to the time the Related
Person became such; (b) is approved by a vote of 80% of the Continuing Directors
and a majority of the entire Board and certain conditions as to price and
procedure are complied with; or (c) is approved by a vote of 80% of Fleet's
outstanding shares of Fleet capital stock entitled to vote generally in the
election of directors, voting as a single class. Under the Fleet Restated
Articles, a "Business Combination" includes any merger or consolidation of Fleet
or any of its subsidiaries into or with a Related Person or any of its
affiliates or associates; any sale, exchange, lease, transfer or other
disposition to or with a Related Person of all, substantially all or any
Substantial Part (defined as assets having a value of more than 5% of the total
consolidated assets of Fleet) of the assets of Fleet or any of its subsidiaries;
any purchase, exchange, lease or other acquisition by Fleet or any of its
subsidiaries of all or any Substantial Part of the assets or business of a
Related Person or any of its affiliates or associates; any reclassification of
securities, recapitalization or other transaction which has the effect, directly
or indirectly, of increasing the proportionate amount of voting shares of Fleet
or any subsidiary which are beneficially owned by a Related Person; and the
acquisition by a Related Person of beneficial ownership of voting securities,
securities convertible into voting securities or any rights, warrants or options
to acquire voting securities of a subsidiary of Fleet; a "Related Person"
includes any person who is the beneficial owner of 10% or more of Fleet's voting
shares prior to the consummation of a Business Combination or any person who is
an affiliate of Fleet and was the beneficial owner of 10% or more of Fleet's
voting shares at any time within the five years preceding the date on which a
binding agreement providing for a Business Combination is authorized by the
Board of Directors; and the "Continuing Directors" are those individuals who
were members of the Fleet Board of Directors prior to the time a Related Person
became the beneficial owner of 10% or more of Fleet's voting stock or those
individuals designated as Continuing Directors (prior to their initial election
as directors) by a majority of the then Continuing Directors. To amend these
provisions, a supermajority vote (80%) of the Board of Directors, a majority
vote of the Continuing Directors and a supermajority vote (80%) of the
stockholders is required unless the amendment is recommended to the stockholders
by a majority of the Board of Directors and not less than 80% of the Continuing
Directors, in which event only the vote provided under Rhode Island law is
required.
    
 
   
     Directors.  The Fleet Restated Articles contain a number of additional
provisions which are intended to delay an insurgent's ability to take control of
Fleet's Board of Directors, even after an insurgent has obtained majority
ownership of the Fleet Common Stock. The Articles provide for a classified Board
of Directors, consisting of three classes of directors serving staggered
three-year terms. Directors of Fleet may only be removed for cause and only (a)
by a vote of the holders of 80% of the outstanding shares of Fleet stock
entitled to vote thereon voting separately as a class at a meeting called for
that purpose or (b) by a vote of a majority of the Continuing Directors and a
majority of the Board of Directors as constituted at that time. Vacancies on the
Board of Directors, whether due to resignation, death, incapacity or an increase
in the number of directors, may only be filled by the Board, acting by a vote of
80% of the directors then in office. The Fleet Restated Articles provide that
the number of directors of Fleet (exclusive of directors to be elected by the
holders of any one or more series of the Preferred Stock voting separately as a
class or classes) that shall constitute the Board of Directors shall be 13,
unless otherwise determined by resolution adopted by a supermajority vote (80%)
of the Board of Directors and a majority of the Continuing Directors. Pursuant
to such an adopted resolution, the number of directors that may serve is
currently fixed at twenty-two, except in the event that quarterly dividends are
not paid on non-voting Preferred Stock as described above, and may only be
increased by the affirmative vote of 80% of the Board of Directors and a
majority of the Continuing Directors. A supermajority vote (80%) of the Board of
Directors, a majority vote of the Continuing Directors and a supermajority vote
(80%) of the outstanding shares of Fleet stock entitled to vote thereon voting
separately as a class are required to amend any of these provisions.

                       COMPARISON OF STOCKHOLDERS' RIGHTS
                      UNDER RHODE ISLAND AND DELAWARE LAW
 
GENERAL
 
     Fleet and Sterling are incorporated in Rhode Island and Delaware,
respectively. Stockholders of Sterling, whose rights as stockholders are
currently governed by the Delaware General Corporation Law ("Delaware law"),
Sterling's Restated Certificate of Incorporation, as amended (the "Sterling
Restated Certificate"), and Sterling's by-laws ("Sterling By-laws") will, upon
consummation of the Merger, automatically become stockholders of Fleet, and
their rights will be governed by Rhode Island law, the Fleet Restated Articles
and Fleet's by-laws ("Fleet By-laws"). Although it is impractical to note all of
the differences, the following is a summary of certain significant differences
between the rights of holders of Fleet Common Stock and those of Sterling Common
Stock. The following does not purport to be a complete description of the
differences between the rights of Fleet and Sterling stockholders. Such
differences may be determined in full by reference to Rhode Island law, Delaware
law, the Fleet Restated Articles, the Sterling Restated Certificate and the
respective Fleet By-laws and Sterling By-laws.
 
VOTING RIGHTS
 
   
     Required Vote For Certain Business Combinations.  Both Rhode Island and
Delaware law generally require approval of a merger, consolidation, dissolution
or sale of all or substantially all of a corporation's assets by the affirmative
vote of the holders of a majority of the outstanding shares of the corporation
entitled to vote thereon, unless otherwise provided in the corporation's
charter. In addition, under Rhode Island law, if any class of stock is entitled
to vote separately, approval of the plan of merger or consolidation, dissolution
or sale of all or substantially all assets also requires the affirmative vote of
the holders of a majority of the shares of each class of stock entitled to vote
as a class thereon. Delaware law, absent a charter provision to the contrary,
does not require such a class vote.
    
 
   
     Pursuant to Delaware law, unless the corporate charter provides otherwise,
no vote of the stockholders of a surviving corporation is required to approve a
merger if: (a) the agreement of merger does not amend in any respect, the
corporation's charter; (b) each share of the corporation's stock outstanding
immediately prior to the effective date of the merger is to be an identical
outstanding or treasury share of the surviving corporation after the effective
date of the merger; and (c) either no shares of common stock of the surviving
corporation and no shares, securities or obligations convertible into such stock
are issued in the merger or the number of authorized unissued shares or treasury
stock of the surviving corporation's common stock to be issued in the merger
plus the number of shares of common stock into which any other securities to be
issued in the merger are initially convertible does not exceed 20% of the
surviving corporation's common stock outstanding immediately prior to the
effective date of the merger.
    
 
   
     Rhode Island law provides that unless the corporate charter provides
otherwise, the vote of the stockholders of a surviving corporation is not
required to approve a merger if (a) the plan of merger does not amend the
corporation's charter and (b) the number of shares of common stock to be issued
in the merger plus the number of shares of common stock into which any other
securities to be issued in the merger are convertible within one year does not
exceed one-third of the total combined voting power of all classes of stock then
entitled to vote for the election of directors which would be outstanding
immediately after the merger.
    
 
   
     No provisions relating to the approval of mergers with unrelated third
parties by holders of the respective corporation's common stock are contained in
the corporate charters of either Fleet or Sterling.
    
 
   
     The Fleet Restated Articles provide that with regard to: (a) the sale,
exchange, lease, transfer or other disposition by Fleet or any of its
subsidiaries of all or substantially all of its assets or businesses (including,
without limitation any securities issued by a subsidiary) to or with a person
who is the beneficial owner of 10% or more of Fleet's voting stock or any
affiliate of Fleet who within the past five years owned 10% or more of Fleet's
outstanding voting stock ("Related Person") or with any affiliate or associate
or such Related Person; (b) the purchase, exchange, lease or other acquisition
by Fleet or any of its subsidiaries (in a single transaction or series of
related transactions) of all, substantially all or a substantial part (as
defined in the Fleet
    
 
                                       58
<PAGE>   64
 
   
Restated Articles) of the assets or businesses of a Related Person or any
affiliate or associate of such Related Person; (c) any merger or consolidation
of Fleet or any subsidiary thereof into or with a Related Person or any
affiliate or associate of a Related Person irrespective of which person is the
surviving entity in such merger or consolidation; (d) any reclassification of
securities, recapitalization or other transaction (other than redemption in
accordance with the terms of the security redeemed) which has the effect,
directly or indirectly, of increasing the proportionate amount of voting shares
of Fleet or any subsidiary thereof which are beneficially owned by a Related
Person, or any partial or complete liquidation, spin-off, split-off or split up
of Fleet or any of its subsidiaries if such transaction has not been approved by
the Board of Directors and 80% of the Continuing Directors; or (e) the
acquisition upon issuance thereof of beneficial ownership by a Related Person of
voting shares or securities convertible into voting shares or any voting
securities or securities convertible into voting securities of any subsidiary of
Fleet or the acquisition upon the issuance thereof of beneficial ownership by a
Related Person of any rights, warrants or options to acquire any of the
foregoing or any combination of the foregoing voting shares or voting securities
of a subsidiary of Fleet (collectively, the transactions described in clauses
(a) through (e) are hereinafter referred to as "Fleet Business Combinations"),
if the proposed Fleet Business Combination does not (x) receive the prior
approval of 80% of the Board of Directors, (y) receive the approval of 80% of
the Continuing Directors and a majority of the Board of Directors and satisfy
certain enumerated qualification tests regarding adequacy of price and procedure
including solicitation of stockholder approval of the Fleet Business Combination
pursuant to a proxy statement complying with the requirements of the Exchange
Act which are specified in Fleet's Restated Articles, or (z) receive the
affirmative vote of holders of 80% of the outstanding shares entitled to vote
thereon to approve a Fleet Business Combination. See "DESCRIPTION OF FLEET
CAPITAL STOCK -- Selected Provisions in the Fleet Restated Articles".
    
 
   
     Sterling's Restated Certificate contains comparable provisions. Pursuant to
Sterling's Restated Certificate, if a proposed Sterling Business Combination (as
hereinafter defined) does not satisfy certain enumerated qualification criteria
regarding the adequacy of price and procedure or the Sterling Business
Combination is not approved by the affirmative vote of a majority of Sterling's
continuing directors, then the affirmative vote of holders of 80% of the voting
power of the then outstanding shares of capital stock entitled, at the time, to
vote in the election of any directors ("Sterling voting stock") is required to
approve a Sterling Business Combination involving any person who: (a)
beneficially owns more than 10% of the outstanding voting power of the Sterling
voting stock; (b) is an affiliate of Sterling and who has at any time within the
two year period immediately preceding the transaction date been the beneficial
owner of 10% or more of the voting power of the then outstanding Sterling voting
stock; or (c) is the assignee of or has succeeded to the beneficial ownership of
any shares of Sterling voting stock which were at any time within the preceding
two year period beneficially owned by an Interested Stockholder, if such
assignment or succession occurred in the course of a transaction or series of
transactions not involving a public offering within the meaning of the
Securities Act, and such assignment or succession was not approved by a majority
of the continuing directors (collectively, the persons referred to in clauses
(a), (b) and (c) are hereinafter referred to as "Interested Stockholders"). A
Sterling Business Combination means (a) any merger or consolidation of Sterling
or any subsidiary with any Interested Stockholder or any other corporation or
entity which is or after the merger or consolidation would be an affiliate of
any Interested Stockholder; (b) any sale, lease, exchange, mortgage, pledge,
transfer or other disposition (in one transaction or a series of transactions)
to or with an Interested Stockholder or an affiliate of an Interested
Stockholder of any assets of Sterling or any subsidiary thereof having an
aggregate fair market value of $1,000,000 or more; (c) the issuance or transfer
by Sterling or any subsidiary (in one transaction or a series of transactions)
of any securities of Sterling or any subsidiary to any Interested Stockholder or
any affiliate of any Interested Stockholder in exchange for cash, securities or
other property having an aggregate fair market value of $1,000,000 or more; (d)
the adoption of any plan or proposal for the liquidation, dissolution or winding
up of Sterling proposed by or on behalf of any Interested Stockholder or any
affiliate of any Interested Stockholder; or (e) any reclassification of
securities (including any reverse stock split) or recapitalization of Sterling
or any merger or consolidation of Sterling with any of its subsidiaries or any
other transaction (whether or not with or into or otherwise involving any
interested stockholder) which has the effect, directly or indirectly, of
increasing the proportionate share of the outstanding shares of any class
    
 
                                       59
<PAGE>   65
 
   
of equity or convertible securities of Sterling or any subsidiary which is
directly or indirectly owned by any Interested Stockholder or any affiliate of
any Interested Stockholder. See "-- State Anti-Takeover Statutes".
    
 
   
     Charter and By-Law Amendments.  To authorize an amendment to the corporate
charter, both Delaware and Rhode Island law generally require the affirmative
vote of the holders of a majority of the outstanding shares entitled to vote
thereon. Both Delaware and Rhode Island law also provide for any class of stock
or series to vote as a class on the proposed amendment if the amendment would
change the number or par value of the aggregate authorized shares of a class.
Delaware law also provides for class voting if the amendment would alter or
modify the powers, preferences or special rights of the shares of such class to
affect such class adversely. Rhode Island law also requires separate class
voting if the amendment would, among other things, change the designations,
preferences, limitations or relative rights of the class, effect an exchange or
create a right of exchange of all or any part of the shares of another class
into shares of the class, or create a new class of shares having rights and
preferences prior and superior to the class.
    
 
   
     Rhode Island law generally, and Delaware law, if so provided in the
charter, provide that the by-laws of a corporation may be amended by the vote of
a majority of the board of directors. The board of directors' authority to
adopt, amend or repeal the by-laws of a corporation does not divest nor limit
the power of stockholders to adopt, amend or repeal by-laws. Any amendment by
the Board of Directors to the by-laws may be subsequently changed by the
affirmative vote of holders of a majority of the shares entitled to vote
thereon.
 
     Sterling's Restated Certificate provides that any repeal, alteration or
amendment to such charter relating to any provision other than the corporate
name, purpose, registered office or agent and number of authorized shares
requires the affirmative vote of holders of at least two-thirds of the total
votes eligible to be cast therefor by stockholders voting together as a single
class at a duly constituted meeting of stockholders called expressly for such
purpose.
 
     Sterling's Restated Certificate provides that the Sterling By-laws may be
adopted, amended, altered or repealed by the affirmative vote of a majority of
the corporation's directors at a duly constituted meeting of the Board of
Directors. Any action by stockholders of Sterling to adopt, amend, alter or
repeal the Sterling By-laws requires the affirmative vote of holders of at least
80% of the total votes eligible to vote thereon, voting together as a single
class at a duly constituted meeting of stockholders called expressly for such
purpose.
 
     Fleet's Restated Articles provides that any amendment, alteration, change
or repeal of the provisions in such charter relating to directors, business
combinations and amendments to the Restated Articles requires the affirmative
vote of 80% of the Board of Directors and a majority of the Continuing Directors
and by the holders of 80% or more of the outstanding shares of capital stock
entitled to vote generally in the election of directors voting separately as a
class.
 
     The Fleet By-laws provide that such by-laws may be altered, amended,
changed or repealed in whole or in part and new By-laws may be adopted in whole
or in part only by the affirmative vote of 80% of the Board of Directors and a
majority of the Continuing Directors or by an affirmative vote of the
stockholders entitled to vote thereon.
 
     Voting Rights of Preferred Stockholders.  The Fleet Restated Articles
provide that the affirmative vote of two-thirds of certain series of the
outstanding Fleet $1 Par Preferred Stock and the Fleet $20 Par Adjustable Rate
Preferred Stock is required to authorize any amendment to the Fleet Restated
Articles which would adversely affect such stockholders or create a class or
series of stock which has preference over the existing series of stock. The
Fleet Restated Articles also provide that, on all matters submitted to a vote of
stockholders (including, without limitation, the election of directors), each
holder of Junior Preferred Stock shall be entitled to 100 votes for each share
of Junior Preferred Stock held. Except as otherwise provided in the Fleet
Restated Articles, Fleet By-laws or a certificate of designation, the holders of
Junior Preferred Stock are entitled to vote together with the Fleet Common Stock
as one class on all matters submitted to a vote of Fleet stockholders.
    
 
   
     The Sterling Restated Certificate provides that holders of Series A
Preferred Stock are entitled to 100 votes on all matters submitted to a vote of
the stockholders of the corporation for each share of Series A
    
 
                                       60

Preferred Stock which they hold and such holders shall vote together with the
holders of shares of Common Stock except as otherwise provided by law or the
Sterling Certificate.
 
SPECIAL MEETINGS; CORPORATE ACTION WITHOUT A MEETING
 
   
     Special Meetings.  Under Delaware law, a special meeting of stockholders
may be called by the board of directors or such other persons as are authorized
by the certificate of incorporation or by-laws. Sterling's Restated Certificate
provides that special meetings may be called by the Chairman of the Board, the
President and by the Board of Directors pursuant to resolutions adopted by the
affirmative vote of a majority of directors, except that if there is an
interested stockholder, the affirmative vote of a majority of the continuing
directors then in office is required. The Sterling By-laws do not contain any
additional provisions relating to the calling of special meetings of
stockholders.
    
 
   
     Rhode Island law permits a special meeting of stockholders to be called by
the president, board of directors or by the holders of 10% or more of the shares
entitled to vote at such meeting, or such other officers or persons specified in
the charter or by-laws. The Fleet By-laws permit special meetings of
stockholders to be called by the Board of Directors pursuant to resolutions
adopted by the majority of the Board, the Chairman of the Board or the
president. In addition, the Fleet By-laws require that the Secretary of Fleet
must call a special meeting of stockholders upon written request of three or
more stockholders holding at least 80% of the outstanding shares of stock of
Fleet entitled to vote at such meeting.
    
 
   
     Corporate Action Without a Meeting.  Delaware law permits corporate action
without a stockholder's meeting, without prior notice and without a vote of
stockholders upon receipt of written consent of that number of shares that would
be necessary to authorize the proposed corporate action at a meeting at which
all shares entitled to vote thereon were present and voting, unless the charter
expressly provides otherwise. Prompt notice of the taking of action without a
meeting by less than unanimous written consent must be given to all stockholders
who have not consented in writing. The Sterling Restated Certificate permits
corporate action without a meeting of the stockholders only if the written
consent of the holders of all of the shares entitled to vote thereon is
obtained.
    
 
     Except for corporate action relating to a merger or consolidation,
acquisition or disposition, Rhode Island law permits corporate action without a
meeting if the charter authorizes such action and the shareholders consenting to
such action would be entitled to cast, at a meeting at which all stockholders
entitled to vote thereon were present, at least the minimum number of votes
which would be required to take such action. Rhode Island law further provides
that corporate action relating to a merger, consolidation, acquisition or
disposition may be taken without a meeting if all stockholders entitled to vote
thereon consent in writing. The Fleet Restated Articles authorize such action by
stockholders if the written consent of stockholders having not less than the
minimum percentage of the total vote statutorily required for the proposed
corporate action is obtained.
 
DIVIDENDS
 
   
     Under Rhode Island law, the board of directors has the power to declare and
pay dividends in cash, property or securities of the corporation unless (a) such
corporation is, or would be thereby made insolvent or (b) the declaration and
payment of such dividend would be contrary to any restrictions contained in the
charter. Rhode Island law further provides that no distribution may be made (i)
if the corporation is and would become unable to pay its debts as they become
due in the usual course of business or (ii) unless the fair value of the net
assets of the corporation remaining after the distribution is at least equal to
the aggregate preferential amount payable to holders of stock with preferential
rights in the event of involuntary liquidation.
    
 
     Under Delaware law, the directors of a corporation are generally permitted
to declare and pay dividends out of surplus or out of net profits for the
current and/or preceding fiscal year, provided that such dividends will not
reduce capital below the amount of capital represented by all classes of stock
having a preference upon the distribution of assets. Also under Delaware law, a
corporation may generally redeem or purchase shares of its stock if such
redemption or purchase will not impair the capital of the corporation.
 
                                       61

LIQUIDATION
 
     Pursuant to both Rhode Island and Delaware law, upon the winding up,
dissolution or liquidation of a corporation, the stockholders of such
corporation are entitled to share in any of the assets distributable to the
holders of the respective corporation's stock upon such liquidation, dissolution
or winding up in accordance with their respective rights and interests. The
Fleet Restated Articles provide that the holders of the Fleet $1 Par Preferred
Stock and the Fleet $20 Par Adjustable Rate Preferred Stock are entitled to a
preference, prior to any payment to the holders of Fleet Common Stock upon the
liquidation, dissolution or winding up of the corporation.
 
   
     Similarly, holders of the Sterling Series A Preferred Stock, none of which
is issued or outstanding, are entitled to a preference upon liquidation,
dissolution or winding up of Sterling. Specifically, upon any voluntary
liquidation, dissolution or winding up and before any payment or distribution of
assets to holders of shares of stock ranking junior (either as to dividends or
upon liquidation, dissolution or winding up) to the Series A Preferred Stock,
the holders of such Series A Preferred Stock are entitled to receive an amount
equal to accrued and unpaid dividends and distributions thereon, whether or not
declared, to the date of such payment, plus an amount equal to the greater of
(a) $5,100 per share or (b) an aggregate amount per share, subject to
adjustment, equal to 100 times the aggregate amount to be distributed per share
to holders of Sterling Common Stock. The Merger Agreement provides that it is a
condition to each party's obligation to effect the Merger that no "Distribution
Date", as such term is defined in the Rights Agreement shall have occurred, the
Rights shall not have become nonredeemable and the Rights shall not have become
exercisable for the capital stock of Fleet upon consummation of the Merger. In
addition, the Rights Agreement, as amended, provides that the Rights will expire
at the Effective Time. See "THE MERGER -- Conditions to Consummation of the
Merger" and "-- Sterling Shareholder Rights Agreement".
    
 
APPRAISAL RIGHTS
 
   
     Under Delaware law, appraisal rights are available in connection with a
statutory merger or consolidation in certain specified situations. Appraisal
rights are not available when a corporation is to be the surviving corporation
and no vote of its stockholders is required to approve the merger. In addition,
unless otherwise provided in the charter, no appraisal rights are available to
holders of shares of any class of stock which is either: (a) listed on a
national securities exchange or designated as a national market system security
on an inter-dealer quotation system by the National Association of Securities
Dealers, Inc. or (b) held of record by more than 2,000 stockholders, unless such
stockholders are required by the terms of the merger to accept anything other
than: (i) shares of stock of the surviving corporation; (ii) shares of stock of
another corporation which are or will be so listed on a national securities
exchange or designated as a national market system security on an interdealer
quotation system by the National Association of Securities Dealers, Inc. or held
of record by more that 2,000 stockholders; (iii) cash in lieu of fractional
shares of such stock; or (iv) any combination thereof. The Sterling Restated
Certificate has no provisions for appraisal rights. Given that (a) Sterling
Common Stock is listed on the NASDAQ National Market and (b) that holders of
Sterling Common Stock will only be receiving shares of Fleet Common Stock, which
is listed on the Stock Exchange, and cash in lieu of fractional shares of Fleet
Common Stock, no appraisal rights are available to Sterling stockholders.
    
 
   
     Under Rhode Island law, appraisal rights are available only in connection
with (a) a statutory merger or consolidation (unless the corporation is to be
the surviving corporation and no vote of its stockholders is required to approve
the merger); (b) acquisitions which require shareholder approval; and (c) sales
or exchanges of all or substantially all of the property and assets of a
corporation in a transaction requiring stockholder approval. In addition, unless
otherwise provided in the charter, no appraisal rights are available to holders
of shares of any class of stock which is (i) registered on a national securities
exchange or included as national market securities in the National Association
of Securities Dealer's automated quotation system or (ii) held of record by not
less than 2,000 stockholders. There are no provisions in the Fleet Restated
Articles providing for appraisal rights.

PROVISIONS RELATING TO DIRECTORS AND OFFICERS
 
   
     Number of Directors.  Under both Rhode Island and Delaware law a
corporation must have a board of directors consisting of at least one director.
The Fleet Restated Articles provide that the Board of Directors shall consist of
13 members (exclusive of directors to be elected by holders of any one or more
series or classes of the Preferred Stock voting separately as a class or
classes) unless otherwise determined from time to time by resolution adopted by
a supermajority (80%) vote of the Board of Directors and a majority of the
Continuing Directors. Pursuant to such an adopted resolution, the number of
directors that may serve is currently fixed at twenty-two. The Sterling Restated
Certificate provides that the number of directors shall be fixed by the Sterling
By-laws; the Sterling By-laws provide that the Board of Directors shall fix the
number of directors by resolution duly adopted by the Board.
    
 
   
     Classification.  Rhode Island and Delaware law both permit classification
of the board of directors if the corporate charter so provides. The charter and
by-laws of both Fleet and Sterling provide for classification of the Board into
three classes as nearly equal in number as possible, with one class being
elected annually.
    
 
   
     Cumulative Voting.  Both Delaware and Rhode Island law permit cumulative
voting for the election of directors, if the corporate charter provides for
cumulative voting. The charter of neither Fleet nor Sterling provides for
cumulative voting for the election of directors.
    
 
   
     Class Voting.  Under Delaware and Rhode Island law, a corporation's charter
may confer upon holders of any class or series of stock the right to elect one
or more directors to serve for such term and to have such voting powers as may
be specified therein. The terms of office and voting powers of directors elected
in the manner so provided in the charter may be either greater or less than
those of any other director or class of directors. Fleet's Restated Articles and
the Sterling Restated Certificate permit class voting by holders of preferred
stock only in the event of certain dividend arrearages. See "-- Rights of
Preferred Stockholders to Elect Directors."
    
 
   
     Stockholder Nominations.  The holders of Fleet Common Stock may nominate
individuals for election to the Board of Directors of Fleet. The procedure
pursuant to which such nomination must occur is set forth in the Fleet By-laws.
The Fleet By-laws specify that nominations of persons for election as director
may be made by or at the direction of the board of directors, or by any holder
of stock entitled to vote thereon who complies with the requisite notice
procedure. The notice procedure requires that a stockholder's nomination of a
person for election as a director must be made in writing and received by the
Secretary of Fleet not less than 30 days prior to the date of the meeting of
stockholders, provided, however, that if fewer than 40 days notice of the
meeting is given to stockholders, the stockholder's nomination notice must be
received not later than the close of business on the seventh day following the
first to occur of the publication or mailing of the notice of the meeting date.
The Fleet By-laws set forth specific requirements as to the content of the
nomination notice.
    
 
   
     Similarly, the Sterling By-laws set forth procedures that must be followed
for stockholders to nominate individuals to the Board of Directors. The Sterling
By-laws provide that any holder of record (both as of the time notice of such
nomination is given by the stockholder and as of the record date for the annual
meeting in question) of Sterling's capital stock entitled to vote for the
election of directors who complies with the notice procedures specified in the
Sterling By-laws may nominate candidates for election as directors. Any
stockholder making such a nomination or his representative must be present in
person at the meeting of stockholders at which the election is to be held. The
Sterling By-laws require that stockholder nominations of persons for election as
director must be made in writing and received at Sterling's principal executive
offices not less than 60 nor more than 180 days prior to the scheduled date of
the stockholder meeting specified in the Sterling By-laws; provided, however,
that if the annual meeting in any year is scheduled for a date earlier than that
date specified in the Sterling By-laws, notice of the stockholder nomination
must be received by Sterling at least 60 days prior to the rescheduled meeting
date if Sterling gives or makes 90 days notice or publication of the meeting
date. If Sterling does not give or make 90 days prior notice of a rescheduled
meeting date, the stockholder's notice will be deemed to be timely if received
by Sterling not later than the 10th day following the earlier of (a) the day on
which notice of the date of the rescheduled meeting was mailed; or (b) the day
on which public disclosure was made; provided, however that notwithstanding the
foregoing, notice by a
    
 
                                       63
<PAGE>   69
 
stockholder shall be deemed to be timely if received by Sterling at least 60
days prior to the rescheduled date of the annual meeting. The Sterling By-laws
set forth the specific requirements regarding the content of the nomination
notice.
 
   
     Rights of Preferred Stockholders to Elect Directors.  Pursuant to the Fleet
Restated Articles, the number of directors on Fleet's Board of Directors will
increase and holders of certain series of outstanding Fleet $1 Par Preferred
Stock and the Fleet $20 Par Adjustable Rate Preferred Stock will be entitled
(without duplication of any increase made pursuant to the terms of any other
series of outstanding Fleet Preferred Stock) as a single class to elect such
additional directors if, at the time of an annual meeting of Fleet, dividends on
such series of preferred stock are in default as a result of not having been
paid or declared and a sum sufficient for the payment thereof irrevocably set
aside in trust for the holders of such shares for six calendar quarters. The
directors so elected by the holders of the series or class of Preferred Stock
upon which the dividend payment is in default will hold such positions until
such time as such dividends are paid or duly provided for.
    
 
   
     Pursuant to the Sterling Restated Certificate, if dividends payable on the
Series A Preferred Stock are in default for six calendar quarters, the holders
of Series A Preferred Stock have the right to call a special meeting (or, if
such holders desire, to cause an election at an annual meeting) and elect two
directors to Sterling's Board of Directors who shall serve until the dividends
in default are paid or duly provided for.
    
 
   
     Removal.  Under Delaware law, any director or the entire board of directors
of a corporation may be removed, with or without cause, by the holders of a
majority of the shares then entitled to elect directors. In the case of a
corporation whose board is classified, stockholders may effect such removal only
for cause unless the charter provides otherwise. In the case of a corporation
having cumulative voting, if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against his removal
would be sufficient to elect him if then cumulatively voted at an election of
the entire board of directors, or if there are classes of directors, at an
election of the class of directors of which he is a part. Under Rhode Island
law, a director may be removed by the stockholders without cause, if the charter
or by-laws so provide but, in the case of a corporation permitting cumulative
voting for the election of directors, only if the number of shares voted against
removal would not be sufficient to elect the director if voted cumulatively. For
a discussion of provisions regarding the removal of directors in the Fleet
Restated Articles, see "DESCRIPTION OF FLEET CAPITAL STOCK -- Selected
Provisions in the Fleet Restated Articles." The Sterling Restated Certificate
provides that a director may be removed from office only with cause and by the
affirmative vote of (a) at least 80% of the total votes which would be eligible
to be cast by stockholders in the election of such director at a duly
constituted meeting of stockholders called expressly for such purpose, or (b) a
majority of the directors then in office, unless at the time of such removal
there shall be an interested stockholder, in which case the affirmative vote of
a majority of the continuing directors then in office shall also be required.
    
 
   
DERIVATIVE SUITS
    
 
   
     Under both Rhode Island and Delaware law, stockholders may bring suits on
behalf of the corporation to enforce the rights of a corporation. Under both
Rhode Island and Delaware law, a person may institute and maintain a suit only
if such person was a stockholder at the time of the transaction which is the
subject of the suit. Under Rhode Island law, upon final judgment and a finding
that the commencement of a derivative action by a stockholder was without
reasonable cause, a court may require the plaintiff(s) to pay to the parties
named as defendant(s) the reasonable expenses including legal fees incurred by
them in defense of such action.
    
 
     Additionally, under Delaware law, the plaintiff generally must be a
stockholder not only at the time of the transaction which is the subject of the
action but also throughout the duration of the derivative suit. Delaware law
also requires that the derivative plaintiff make demand on the directors of the
corporation to assert the corporate claim unless such demand would be futile
before the suit may be prosecuted by the derivative plaintiff.

CONFLICT OF INTEREST TRANSACTIONS
    
 
   
     Both Rhode Island and Delaware law provide that contracts or other
transactions between a corporation and one or more of its directors or officers
or between a corporation and any other corporation or other entity with respect
to which any of the corporation's directors or officers are directors, officers
or financially interested persons, are permitted if: (a) the material facts as
to the contract or transaction and the director's relationship or interest are
disclosed to the board of directors or committee and the board of directors or
committee authorizes the contract in good faith by the affirmative vote of a
majority of disinterested directors (even though less than a quorum); (b) if the
material facts as to the contract or transaction and the director's relationship
or interest are disclosed to the stockholders entitled to vote thereon and it is
approved in good faith by vote of the stockholders, or (c) if the contract or
transaction is fair and reasonable as to the corporation as of the time it is
approved by the board of directors, a committee, or the stockholders. Neither
the Fleet Restated Articles or Fleet By-Laws nor the Sterling Restated
Certificate or Sterling By-Laws contain additional provisions governing
transactions involving interested directors.
    
 
   
STATE ANTI-TAKEOVER STATUTES
    
 
   
     Pursuant to Delaware law, a corporation shall not engage in any business
combination with an interested stockholder (generally defined as the holder of
15% or more of the corporation's voting stock) for a period of three years
following the date that such stockholder became an interested stockholder,
unless (a) the board of directors approved either the business combination or
transaction prior to the date that the interested stockholder became an
interested stockholder; (b) upon consummation of the transaction which resulted
in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned by (i) any
persons who are directors and also officers and (ii) employee stock plans in
which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer; or (c) on or subsequent to the date the stockholder became an interested
stockholder, the board of directors approved the transaction and the
stockholders approved the transaction, not by written consent, but at an annual
or special meeting of shareholders, with an affirmative vote of two-thirds of
the outstanding voting stock, excluding any stock owned by the interested
stockholder. The restrictions prescribed by the statute will not be applicable
if (a) a corporation's charter or by-laws contain a provision expressly
providing that the corporation shall not be subject to such statutory
restrictions; (b) if the corporation does not have a class of voting stock that
is (i) listed on a national securities exchange; (ii) authorized for quotation
on an inter-dealer quotation system of a registered national securities
association; or (iii) held of record by more than 2,000 stockholders, unless any
of the foregoing results from action taken directly or indirectly by an
interested stockholder or from a transaction in which a person becomes an
interested stockholder; or (c) a stockholder becomes an interested stockholder
inadvertently and divests sufficient shares so that the stockholder ceases to be
an interested stockholder and would not at any time during the three year period
immediately prior have been an interested stockholder but for the inadvertent
acquisition; or (d) the business combination is proposed prior to the
consummation or abandonment of and subsequent to the earlier of the public
announcement or required notice to interested stockholders of a proposed
transaction: (i) involving (A) a merger or consolidation (except a merger in
respect of which no vote of the stockholders of the corporation is required);
(B) a sale, lease, exchange, mortgage, pledge, transfer or other disposition
having an aggregate market value equal to 50% or more of either the aggregate
market value of all the assets of the corporation determined on a consolidated
basis or the aggregate market value of all the outstanding stock of the
corporation; or (C) a proposed tender offer or exchange offer for 50% or more of
the outstanding voting stock of the corporation; (ii) is with or by a person who
either was not an interested stockholder during the previous 3 years or who
became an interested stockholder with the approval of the corporation's board of
directors; and (iii) is approved or not opposed by a majority of the members of
the board of directors who were directors prior to any person becoming an
interested stockholder during the previous 3 years or were recommended for
election or elected to succeed such directors by a majority of directors.
Neither the Sterling Restated Certificate nor the Sterling By-Laws contain any
provision expressly providing that the corporation will not be subject to the
restrictions prescribed by the statute. See "-- Voting Rights -- Required Vote
for Certain Business Combinations".
    
 
                                       65
<PAGE>   71
 
   
     Pursuant to Rhode Island law, a corporation shall not engage in any
business combination with an interested stockholder (generally defined as the
beneficial owner of 10% or more of the corporation's outstanding voting stock or
an affiliate of the corporation who within 5 years prior to the date in question
was the beneficial owner of 10% or more of the corporation's outstanding voting
stock) for a period of five (5) years following the date the stockholder became
an interested stockholder unless either (a) the board of directors of the
corporation approved the business combination or transaction prior to the date
the stockholder became an interested stockholder; (b) holders of two-thirds
( 2/3) of the outstanding voting stock, excluding any stock owned by the
interested stockholder, have approved the business combination; or (c) the
business combination meets each of the following conditions: (i) the nature,
form and adequacy of the consideration to be received by the corporation's
stockholders in the business combination transaction satisfies certain specific
enumerated criteria; (ii) the holders of all the outstanding shares of stock of
the corporation not beneficially owned by the interested stockholder are
entitled to receive the specified consideration in the business combination
transaction; and (iii) the interested stockholder shall not acquire additional
shares of voting stock of the corporation except in certain specifically
identified transactions.
    
 
   
     The restrictions prescribed by the statute will not be applicable to any
business combination (a) involving a corporation that does not have a class of
voting stock registered under the Exchange Act, unless the charter provides
otherwise; (b) involving a corporation which did not have a class of voting
stock registered under the Exchange Act at the time corporation's charter was
amended to provide that the corporation shall be subject to the statutory
restriction provisions and the interested stockholder's stock acquisition date
is prior to the effective date of the charter amendment; (c) involving a
corporation whose original charter contains a provision expressly electing not
to be subject to the statutory restrictions or which adopted an amendment
expressly electing not to be subject to the statutory restrictions either to its
by-laws prior to March 31, 1991 or to its charter if such charter amendment is
approved by the affirmative vote of holders, other than the interested
shareholder, of two-thirds of the outstanding voting stock, excluding the voting
stock of the interested stockholder; provided, that the amendment to the charter
shall not be effective until 12 months after the vote of the stockholders and
shall not apply to any business combination of the corporation with an
interested stockholder whose stock acquisition date is on or prior to the
effective date of the amendment; or (d) involving a corporation with an
interested stockholder who became an interested stockholder inadvertently, if
the interested stockholder divests itself of such number of shares so that it is
no longer the beneficial owner of 10% of the outstanding voting stock and, but
for such inadvertent ownership, was not an interested stockholder within the
5-year period preceding the announcement of the business combination. Neither
the Fleet Restated Articles nor the original Fleet charter contain any
provisions expressly relating to the non-applicability of the statute.

     The cost of solicitation of proxies from Sterling stockholders, including
the cost of reimbursing brokerage houses and other custodians, nominees or
fiduciaries for forwarding proxies and proxy statements to their principals,
will be borne by Fleet. Fleet will not seek reimbursement from Sterling of such
costs. Solicitation may be made in person or by telephone or telegraph by

compensation therefor. Fleet and Sterling estimate the total cost to solicit
proxies to be $7,000, including $500 incurred through February 1, 1994.

the Secretary of State of the State of Rhode Island (the "Rhode Island
Secretary"), in each case on the Closing Date (as defined in Section 9.01
hereof). The term "Effective Time" shall be the date and time when the Merger
becomes effective, as set forth in the Certificate of Merger and the Articles of
Merger.
 
     1.03  EFFECTS OF THE MERGER.  At and after the Effective Time, the Merger
shall have the effects set forth in Sections 259 and 261 of the DGCL and Section
7-1.1-69 of the RIBCL.
 
     1.04  CONVERSION OF COMPANY COMMON STOCK.
 
          (a)  At the Effective Time, subject to Section 2.02(c) hereof, each
     share of the common stock, par value $0.10 per share, of the Company (the
     "Company Common Stock") issued and outstanding immediately prior to the
     Effective Time (other than shares of Company Common Stock held (x) in the
     Company's treasury or (y) directly or indirectly by Parent or the Company
     or any of their respective Subsidiaries (as defined below) (except for
     Dissenting Shares (as such term is defined in Section 1.05 hereof) and
     Trust Account Shares and DPC Shares (as such terms are defined in Section
     1.04(b) hereof)) shall, by virtue of this Agreement and without any action
     on the part of the holder thereof, be converted into and exchangeable for
     the number of shares (the "Exchange Ratio") of the common stock,
<PAGE>   80
 
     par value $1.00 per share of Parent ("Parent Common Stock") (together with
     the number of Parent Rights (as defined in Section 4.02 hereof) associated
     therewith), rounded to the nearest thousandth of a share, determined by
     dividing $39.50 by the Average Closing Price (as defined below); provided,
     that (I) if the Average Closing Price is equal to or greater than $39.24,
     the Exchange Ratio shall be 1.0066 (the "Minimum Exchange Ratio"); and (II)
     if the Average Closing Price is equal to or less than $29.01, the Exchange
     Ratio shall be 1.3616 (the "Maximum Exchange Ratio"), provided, however,
     that if the Average Closing Price is equal to or less than $25.59, the
     Company shall have the right, waivable by it, to terminate this Agreement
     pursuant to Section 8.01(g) hereof, unless Parent elects, at its option, to
     adopt as the Exchange Ratio the "Adjusted Maximum Exchange Ratio" which
     shall be determined by dividing $34.84 by the Average Closing Price. For
     purposes of this Agreement, the "Average Closing Price" means the average
     closing sale price per share of Parent Common Stock on the New York Stock
     Exchange (the "Stock Exchange") (as reported by The Wall Street Journal or,
     if not reported thereby, another authoritative source), for the 20 Stock
     Exchange trading days ending on the tenth business day after the date on
     which the last of the regulatory approvals required to consummate the
     transactions contemplated hereby is obtained. All of the shares of Company
     Common Stock converted into Parent Common Stock pursuant to this Article I
     shall no longer be outstanding and shall automatically be cancelled and
     shall cease to exist, and each certificate (each a "Certificate")
     previously representing any such shares of Company Common Stock shall
     thereafter represent the right to receive (i) the number of whole shares of
     Parent Common Stock and (ii) cash in lieu of factional shares into which
     the shares of Company Common Stock represented by such Certificate have
     been converted pursuant to this Section 1.04(a) and Section 2.02(c) hereof.
     Certificates previously representing shares of Company Common Stock shall
     be exchanged for certificates representing whole shares of Parent Common
     Stock and cash in lieu of fractional shares issued in consideration
     therefor upon the surrender of such Certificates in accordance with Section
     2.02 hereof, without any interest thereon. If prior to the Effective Time
     Parent should split or combine its common stock, or pay a dividend or other
     distribution in such common stock, then the Exchange Ratio (including, if
     applicable, the Minimum Exchange Ratio, the Maximum Exchange Ratio, and the
     Adjusted Maximum Exchange Ratio) shall be appropriately adjusted to reflect
     such split, combination, dividend or distribution.
 
          (b)  At the Effective Time, all shares of Company Common Stock that
     are owned by the Company as treasury stock and all shares of Company Common
     Stock that are owned directly or indirectly by Parent or the Company or any
     of their respective Subsidiaries (other than shares of Company 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, and shares of Parent Common Stock which
     are similarly held, whether held directly or indirectly by Parent or the
     Company, as the case may be, being referred to herein as "Trust Account
     Shares") and other than any shares of Company Common Stock held by Parent
     or the Company or any of their respective Subsidiaries in respect of a debt
     previously contracted (any such shares of Company Common Stock, and shares
     of Parent Common Stock which are similarly held, whether held directly or
     indirectly by Parent or the Company, being referred to herein as "DPC
     Shares")) shall be cancelled and shall cease to exist and no stock of
     Parent or other consideration shall be delivered in exchange therefor. All
     shares of Parent Common Stock and Parent Preferred Stock that are owned by
     the Company or any of its Subsidiaries (other than Trust Account Shares and
     DPC Shares) shall become treasury stock of Parent.
 
     1.05  DISSENTERS' RIGHTS.  Notwithstanding anything in this Agreement to
the contrary and unless otherwise provided by applicable law, shares of Company
Common Stock which are issued and outstanding immediately prior to the Effective
Time and which are owned by shareholders who, pursuant to applicable law, (a)
deliver to the Company, before the taking of the vote of the Company's
shareholders on the Merger, written demand for the appraisal of their shares, if
the Merger is effected, and (b) whose shares are not voted in favor of the
Merger, nor consented thereto in writing (the "Dissenting Shares"), shall not be
converted into Parent Common Stock, unless and until such holders shall have
failed to perfect or shall have effectively withdrawn or lost their right of
appraisal and payment under applicable law. If any such holder shall have failed
to perfect or shall have effectively withdrawn or lost such right of appraisal,
the Company Common Stock of such holder shall thereupon be deemed to have been
converted into the right to receive and become
 
                                        2
<PAGE>   81
 
exchangeable for, at the Effective Time, that number of whole shares of Parent
Common Stock and cash in lieu of fractional shares determined pursuant to
Section 1.04(a) and Section 2.02(c) hereof.
 
     1.06  OPTIONS.  At the Effective Time, each option granted by the Company
to purchase shares of Company Common Stock which is outstanding and unexercised
immediately prior thereto shall be converted automatically into an option under
the Fleet Financial Group, Inc. 1992 Employee Stock Option and Restricted Stock
Plan (the "Parent Stock Option Plan") to purchase shares of Parent Common Stock
in an amount and at an exercise price determined as provided below (and
otherwise subject to the terms (including those providing for accelerated
vesting) of the Sterling Bancshares Corporation Amended and Restated Stock
Option Plan (the "Company Stock Plan"):
 
          (1)  The number of shares of Parent Common Stock to be subject to the
     new option shall be equal to the product of the number of shares of Company
     Common Stock subject to the original option and the Exchange Ratio,
     provided, that any fractional shares of Parent Common Stock resulting from
     such multiplication shall be rounded down to the nearest share; and
 
          (2)  The exercise price per share of Parent Common Stock under the new
     option shall be equal to the exercise price per share of Company Common
     Stock under the original option divided by the Exchange Ratio, provided,
     that such exercise price shall be rounded up to the nearest cent.
 
The adjustment provided herein with respect to any options which are "incentive
stock options" (as defined in Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code")) shall be and is intended to be effected in a manner
which is consistent with Section 424(a) of the Code. The duration and other
terms of the new option shall be the same as the original option, except that
all references to the Company shall be deemed to be references to Parent.
 
     1.07  ESOP.  The parties hereto agree that, effective as of the Effective
Time (or as soon thereafter as practicable), the Bank's Employee Stock Ownership
Plan and Trust (the "Bank ESOP") will be terminated in accordance with
applicable law and regulations, with any loan balance outstanding immediately
prior to the Effective Time repaid from the proceeds of unallocated shares of
Company Common Stock held by the Bank ESOP.
 
     1.08  ARTICLES OF INCORPORATION.  At the Effective Time, the Articles of
Incorporation of Parent, as in effect at the Effective Time, shall be the
Articles of Incorporation of the Surviving Corporation.
 
     1.09  BY-LAWS.  At the Effective Time, the By-Laws of Parent, as in effect
immediately prior to the Effective Time, shall be the By-Laws of the Surviving
Corporation until thereafter amended in accordance with applicable law.
 
     1.10  DIRECTORS AND OFFICERS.  The directors and officers of Parent
immediately prior to the Effective Time shall be the directors and officers of
the Surviving Corporation, each to hold office in accordance with the Articles
of Incorporation and By-Laws of the Surviving Corporation until their respective
successors are duly elected or appointed and qualified.
 
     1.11  TAX CONSEQUENCES.  It is intended that the Merger shall constitute a
reorganization within the meaning of Section 368(a) of the Code, and that this
Agreement shall constitute a "plan of reorganization" for the purposes of
Section 368 of the Code.
 
     1.12  STOCK OPTION AGREEMENT.  In order to protect the integrity of this
Agreement, Parent and the Company are entering into, as of the date of this
Agreement, a stock option agreement (the "Stock Option Agreement"), providing
for the issuance by the Company of shares of Company Common Stock, as set forth
therein.

                                   ARTICLE II
 
                               EXCHANGE OF SHARES
 
     2.01  PARENT TO MAKE SHARES AVAILABLE.  At or prior to the Effective Time,
Parent shall deposit, or shall cause to be deposited, with a bank or trust
company selected by Parent (and reasonably acceptable to the Company) (the
"Exchange Agent"), for the benefit of the holders of Certificates, for exchange
in accordance with this Article II, certificates representing the shares of
Parent Common Stock and the cash in lieu of fractional shares (such cash and
certificates for shares of Parent Common Stock, together with any dividends or
distributions with respect thereto, being hereinafter referred to as the
"Exchange Fund") to be issued pursuant to Section 1.04 and paid pursuant to
Section 2.02(a) in exchange for outstanding shares of Company Common Stock.
 
     2.02  EXCHANGE OF SHARES.
 
          (a)  As soon as practicable after the Effective Time, and in no event
     later than three business days thereafter, the Exchange Agent shall 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 certificates representing
     the shares of Parent Common Stock and the cash in lieu of fractional shares
     into which the shares of Company Common Stock represented by such
     Certificate or Certificates shall have been converted pursuant to this
     Agreement. The Company shall have the right to approve both the letter of
     transmittal and the instructions. Upon surrender of a Certificate for
     exchange and cancellation to the Exchange Agent, together with such letter
     of transmittal, duly executed, the holder of such Certificates shall be
     entitled to receive in exchange therefor (x) a certificate representing
     that number of whole shares of Parent Common Stock to which such holder of
     Company Common Stock shall have become entitled pursuant to the provisions
     of Article I hereof and (y) a check representing the amount of cash in lieu
     of fractional shares, if any, which such holder has the right to receive in
     respect of the Certificate surrendered pursuant to the provisions of this
     Article II, and the Certificate so surrendered shall forthwith be
     cancelled. No interest will be paid or accrued on the cash in lieu of
     fractional shares and unpaid dividends and distributions, if any, payable
     to holders of Certificates.
 
          (b)  After the Effective Time, there shall be no transfers on the
     stock transfer books of the Company of the shares of Company Common Stock
     which were issued and outstanding immediately prior to the Effective Time.
     If, after the Effective Time, Certificates representing such shares are
     presented for transfer to the Exchange Agent, they shall be cancelled and
     exchanged for certificates representing shares of Parent Common Stock as
     provided in this Article II.
 
          (c)  Notwithstanding anything to the contrary contained herein, no
     certificates or scrip representing fractional shares of Parent Common Stock
     shall be issued upon the surrender for exchange of Certificates, no
     dividend or distribution with respect to Parent Common Stock shall be
     payable on or with respect to any fractional share, and such fractional
     share interests shall not entitle the owner thereof to vote or to any other
     rights of a shareholder of the Company. In lieu of the issuance of any such
     fractional share, Parent shall pay to each former shareholder of the
     Company who otherwise would be entitled to receive a fractional share of
     Parent Common Stock, an amount in cash determined by multiplying (i) the
     closing sale price of Parent Common Stock on the Stock Exchange as reported
     by The Wall Street Journal for the trading day immediately preceding the
     date of the Effective Time by (ii) the fraction of a share of Parent Common
     Stock to which such holder would otherwise be entitled to receive pursuant
     to Section 1.04 hereof.
 
          (d)  Any portion of the Exchange Fund that remains unclaimed by the
     shareholders of the Company for eighteen months after the Effective Time
     shall be paid to Parent. Any shareholders of the Company who have not
     theretofore complied with this Article II shall thereafter look only to
     Parent for payment of their shares of Parent Common Stock, cash in lieu of
     fractional shares and unpaid dividends and distributions of the Parent
     Common Stock deliverable in respect of each share of Company Common
 
                                        4
<PAGE>   83
 
     Stock such shareholder holds as determined pursuant to this Agreement, in
     each case, without any interest thereon. Notwithstanding the foregoing,
     none of Parent, the Company, the Exchange Agent or any other person shall
     be liable to any former holder of shares of Company Common Stock for any
     amount 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 the making of an affidavit of that fact by the person
     claiming such Certificate to be lost, stolen or destroyed and, if required
     by Parent, the posting by such person of a bond in such amount as Parent
     may direct as indemnity against any claim that may be made against it with
     respect to such Certificate, the Exchange Agent will issue in exchange for
     such lost, stolen or destroyed Certificate, the shares of Parent Common
     Stock and cash in lieu of fractional shares deliverable in respect thereof
     pursuant to this Agreement.
 
                                  ARTICLE III
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     The Company hereby represents and warrants to Parent as follows:
 
     3.01  CORPORATE ORGANIZATION.
 
          (a)  The Company is a corporation duly organized, validly existing and
     in good standing under the laws of the State of Delaware. The Company has
     the corporate power and authority to own or lease all of its properties and
     assets and to carry on its business as it is now being conducted, and is
     duly licensed or qualified to do business in each jurisdiction in which the
     nature of the business conducted by it or the character or location of the
     properties and assets owned or leased by it makes such licensing or
     qualification necessary, except where the failure to be so licensed or
     qualified would not have a Material Adverse Effect (as defined below) on
     the Company and its Subsidiaries taken as a whole. As used in this
     Agreement, the term "Material Adverse Effect" means, with respect to Parent
     or the Company, as the case may be, a material adverse change in or effect
     on the business, financial condition or results of operations of such party
     and its subsidiaries taken as a whole, other than any such effect
     attributable to or resulting from changes in interest rates or general
     economic conditions. As used in this Agreement, the word "Subsidiary" when
     used with respect to any party means any corporation, partnership or other
     organization, whether incorporated or unincorporated, which is consolidated
     with such party for financial purposes. The Company is duly registered as a
     bank holding company under the Bank Holding Company Act of 1956, as amended
     (the "BHC Act"). The Certificate of Incorporation and By-laws of the
     Company, copies of which have previously been made available to Parent, are
     true and complete copies of such documents as in effect as of the date of
     this Agreement.
 
          (b)  The Bank is a savings bank duly organized, validly existing and
     in good standing under the laws of The Commonwealth of Massachusetts. The
     deposit accounts of the Bank are insured by the Federal Deposit Insurance
     Corporation (the "FDIC") through the Bank Insurance Fund (the "BIF") and by
     the Mutual Savings Central Fund, Inc., through the Deposit Insurance Fund,
     to the fullest extent permitted by law, and all premiums and assessments
     required in connection therewith have been paid by the Bank. Each of the
     Company's other Subsidiaries that is a "Significant Subsidiary" (defined
     for purposes of this Agreement to mean subsidiaries other than those that
     are either inactive or have an immaterial amount of assets) is a
     corporation, partnership or business trust duly organized, and, in the case
     of any such corporation, is validly existing and in good standing under the
     laws of its jurisdiction of incorporation. Each Significant Subsidiary of
     the Company has the power and authority to own or lease all of its
     properties and assets and to carry on its business as it is now being
     conducted, and is duly licensed or qualified to do business in each
     jurisdiction in which the nature of the business conducted by it or the
     character or the location of the properties and assets owned or leased by
     it makes such licensing or qualification necessary, except where the
     failure to be so licensed or qualified would not have a Material Adverse
     Effect on the Company and its Subsidiaries taken as a whole. The articles
     of organization, by-laws and similar governing documents of each
     Significant Subsidiary of the Company, copies of which
 
                                        5
<PAGE>   84
 
     have previously been made available to Parent, are true and complete copies
     of such documents as in effect as of the date of this Agreement.
 
          (c)  The minute books of the Company and each of its Subsidiaries
     contain true and complete records in all material respects of all meetings
     since January 1, 1986 of their respective shareholders and Boards of
     Directors.
 
     3.02  CAPITALIZATION.
 
          (a)  The authorized capital stock of the Company consists of
     15,000,000 shares of Company Common Stock and 5,000,000 shares of preferred
     stock, par value $0.10 per share (the "Company Preferred Stock"). As of the
     date of this Agreement, there are (x) 3,017,312 shares of Company Common
     Stock issued and outstanding and 726,588 shares of Company Common Stock
     held in the Company's treasury, (y) no shares of Company Common Stock
     reserved for issuance, except for 268,000 shares of Company Common Stock
     reserved for issuance upon exercise of outstanding stock options pursuant
     to the Company Stock Plan and 250,000 shares of Company Common Stock
     reserved for issuance pursuant to the Company Dividend Reinvestment and
     Stock Purchase Plan (the "Company DRP"), and (z) no shares of Company
     Preferred Stock issued or outstanding, held in the Company's treasury or
     reserved for issuance, except for 100,000 shares of Company Series A Junior
     Participating Cumulative Preferred Stock reserved for issuance upon
     exercise of the rights (the "Company Rights") distributed to holders of
     Company Common Stock pursuant to the Shareholder Rights Agreement dated as
     of January 23, 1989, between the Company and The First National Bank of
     Boston, as Rights Agent (the "Company Rights Agreement"). All of the issued
     and outstanding shares of Company Common Stock have been duly authorized
     and validly issued and are fully paid, nonassessable and free of preemptive
     rights. Except as referred to above or reflected in Section 3.02 of the
     Disclosure Schedule which is being delivered to Parent concurrently
     herewith (the "Company Disclosure Schedule"), and except for the Company
     Stock Plan, the Company Rights Agreement and the Stock Option Agreement,
     the Company does not have and is not bound by any outstanding
     subscriptions, options, warrants, calls, commitments or agreements of any
     character calling for the purchase or issuance of any shares of Company
     Common Stock or Company Preferred Stock or any other equity security of the
     Company or any securities representing the right to purchase or otherwise
     receive any shares of Company Common Stock, Company Preferred Stock or any
     other equity security of the Company. The names of the optionees, the date
     of each option to purchase Company Common Stock granted, the number of
     shares subject to each such option, and the price at which each such option
     may be exercised under the Company Stock Plan are set forth in Section 3.02
     of the Company Disclosure Schedule.
 
          (b)  Section 3.02 of the Company Disclosure Schedule sets forth a true
     and correct list of all of the Company Subsidiaries as of the date of this
     Agreement. The Company owns, directly or indirectly, all of the issued and
     outstanding shares of capital stock of each of the Company Subsidiaries
     (or, in the case of Company Subsidiaries that are not corporations, all of
     the outstanding partnership interests or beneficial interests, as the case
     may be), free and clear of all liens, charges, encumbrances and security
     interests whatsoever, and all of such shares of capital stock are duly
     authorized and validly issued and are fully paid, nonassessable and free of
     preemptive rights. No Company Subsidiary has or is bound by any outstanding
     subscriptions, options, warrants, calls, commitments or agreements of any
     character calling for the purchase or issuance of any shares of capital
     stock or any other equity security of such Subsidiary or any securities
     representing the right to purchase or otherwise receive any shares of
     capital stock or any other equity security of such Subsidiary. Assuming
     compliance by Parent with Section 1.06 hereof, at the Effective Time, there
     will not be any outstanding subscriptions, options, warrants, calls,
     commitments or agreements of any character by which the Company or any of
     its Subsidiaries will be bound calling for the purchase or issuance of any
     shares of the capital stock of the Company or any of its Subsidiaries,
     other than shares reserved for issuance under the Company DRP and the
     Rights.
 
     3.03  AUTHORITY; NO VIOLATION.
 
          (a)  The Company has all necessary corporate power and authority to
     execute and deliver this Agreement and to consummate the transactions
     contemplated hereby. The execution and delivery of this
 
                                        6
<PAGE>   85
 
   
     Agreement and the Stock Option Agreement by the Company and the
     consummation by the Company of the transactions contemplated by this
     Agreement have been duly and validly approved by the Board of Directors of
     the Company. The Board of Directors of the Company has directed that this
     Agreement and the transactions contemplated hereby be submitted to the
     Company's shareholders for consideration at a meeting of such shareholders
     and, except for the adoption of this Agreement by the requisite vote of the
     Company's shareholders, no other corporate proceedings on the part of the
     Company are necessary to approve this Agreement and to consummate the
     transactions contemplated hereby. This Agreement has been duly and validly
     executed and delivered by the Company and (assuming adoption of the
     Agreement by the requisite vote of the Company's shareholders and the due
     authorization, execution and delivery by Parent) constitutes a valid and
     binding obligation of the Company, enforceable against the Company 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.
    
 
          (b)  The Bank has all necessary corporate power and authority to
     execute and deliver the Bank Merger Agreement and to consummate the
     transactions contemplated thereby. Upon the due and valid approval of the
     Bank Merger Agreement by the Board of Directors of the Bank and by the
     Company as the sole shareholder of the Bank, no other corporate proceedings
     on the part of the Bank will be necessary to consummate the transactions
     contemplated thereby. The Bank Merger Agreement, upon execution and
     delivery by the Bank, will be duly and validly executed and delivered by
     the Bank and will (assuming due authorization, execution and delivery by
     Massachusetts Bank) constitute a valid and binding obligation of the Bank,
     enforceable against the Bank 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.
 
          (c)  Except as set forth in Section 3.03 of the Company Disclosure
     Schedule, neither the execution and delivery of this Agreement by the
     Company or the Bank Merger Agreement by the Bank, nor the consummation by
     the Company or the Bank, as the case may be, of the transactions
     contemplated hereby or thereby, nor compliance by the Company or the Bank
     with any of the terms or provisions hereof or thereof, will (i) violate any
     provision of the Certificate of Incorporation or By-Laws of the Company or
     the Amended and Restated Charter or By-laws of the Bank, (ii) assuming that
     the consents and approvals referred to in Section 3.04 hereof are duly
     obtained, (x) violate any statute, code, ordinance, rule, regulation,
     judgment, order, writ, decree or injunction applicable to the Company or
     the Bank, or (y) violate, result in a breach of any provision of,

     pledge, security interest, charge or other encumbrance upon any of the
     respective properties or assets of the Company or any of its Significant

             (iii)  there has not been any agreement, contract or commitment
        entered into, or agreed to be entered into, except for those in the

in the aggregate, (i) have a Material Adverse Effect on the Company and its
Subsidiaries taken as a whole, or (ii) as of the date hereof, prevent or
materially and adversely affect the Company's ability to consummate the
transactions contemplated hereby.

local, information returns and tax returns required to be filed by it on or
prior to the date hereof (all such returns being true and complete in all
material respects) and has paid or made provisions for the payment of all taxes

for which the Company or any of its Subsidiaries may be liable in its own right
or as transferee of the assets of, or successor to, any corporation, person,
association, partnership, joint venture or other entity, are adequate under GAAP
and are sufficient to cover all such taxes due, except where the failure to so
accrue would not have a Material Adverse Effect on the Company and its
Subsidiaries taken as a whole. The Company has not received any written notice
of any pending tax examinations or audits, material disputes or claims asserted
for taxes or assessments upon the
 
                                        9

Company or any of its Subsidiaries, nor has the Company or any of its

     qualified, (iii) with respect to each Plan which is subject to Title IV of

     its latest valuation date, exceed the then current value of the assets of
     such Plan allocable to such accrued benefits, (iv) no liability under Title
     IV of ERISA has been incurred by the Company, its Significant Subsidiaries

     the Code, and (vii) neither the Company, its Significant Subsidiaries nor

     502(i) of ERISA or a tax imposed pursuant to Section 4975 or 4976 of the
     Code, which would have a Material Adverse Effect on the Company and its
     Subsidiaries taken as a whole.

not in default under any, applicable law, statute, order, rule or regulation of
any Governmental Entity relating to the Company or any of its Subsidiaries,

liens, mortgages, security interests, and pledges that do not have a Material

of the consolidated operations and changes in shareholders' equity and
consolidated financial position of Parent and its Subsidiaries for the
respective fiscal periods or as of the respective dates therein set forth and
each of such statements (including the related notes, where applicable) has

             (iii)  there has not been any agreement, contract or commitment
        entered into, or agreed to be entered into, except for those in the

        principles.
 
     4.08  LEGAL PROCEEDINGS.  There are no pending or to the knowledge of
Parent, threatened, legal, administrative, arbitral or other proceedings,
claims, actions or governmental investigations of any nature against Parent or

materially and adversely affect Parent's ability to consummate the transactions
contemplated hereby.

to its shareholders since January 1, 1988, and, as of their respective dates, no
such Parent Reports contained any untrue statement of a material fact or omitted

default under any, applicable law, statute, order, rule or regulation of any
Governmental Entity relating to Parent or any of its Subsidiaries, except where
the failure to hold such license, franchise, permit or authorization or such
noncompliance or default would not have a Material Adverse Effect on Parent, and
neither Parent nor any of its Subsidiaries has received notice of violation of
any material violations of any of the above.
 
     4.12  OWNERSHIP OF COMPANY COMMON STOCK; AFFILIATES AND
ASSOCIATES.  Neither Parent nor any of its affiliates or associates (as such

defined in DGCL Section 203(C)(2)) of the Company.
 
     4.13  AGREEMENTS WITH REGULATORY AGENCIES.  Except as set forth in Section
4.13 of the Parent Disclosure Schedule or as disclosed in Parent's Annual Report

Subsidiaries is subject to any cease-and-desist or other order issued by, or is

or other Governmental Entity that restricts in any material respect the conduct
of its business or that relates in any manner to its capital adequacy, its
credit policies or its management, nor has Parent or any of its Subsidiaries
been notified by any Regulatory Agency of other Governmental Entity that it is
considering issuing or requesting any Regulatory Agreement.

     affect the regulatory approvals required to consummate the Merger; or
 
          (f)  agree to do any of the foregoing.

                             ADDITIONAL AGREEMENTS
 
     6.01  REGULATORY MATTERS.
 
          (a)  The Company shall promptly prepare and file with the SEC the
     Proxy Statement and Parent shall promptly prepare and file with the SEC the
     S-4, in which the Proxy Statement will be included as a prospectus. Each of
     the Parent and the Company shall use their best efforts to have the S-4
     declared effective under the Securities Act as promptly as practicable
     after such filing, and the Company shall thereafter promptly mail the Proxy
     Statement to its shareholders. Parent shall also use its best efforts to
     obtain all necessary state securities law or "Blue Sky" permits and
     approvals required to carry out the transactions contemplated by this
     Agreement and the Bank Merger Agreement, and the Company shall furnish all
     information concerning the Company and the holders of the Company Common
     Stock as may be reasonably requested in connection with any such action.
 
          (b)  The parties hereto shall cooperate with each other and use their
     best efforts to promptly prepare and file all necessary documentation, to
     effect all applications, notices, petitions and filings, and to obtain as
     promptly as practicable all permits, consents, approvals and authorizations
     of all third parties and Governmental Entities which are necessary or
     advisable to consummate the transactions contemplated by this Agreement
     (including without limitation the Merger and the Bank Merger). The Company
     and Parent shall have the right to review in advance, and to the extent
     practicable each will consult with the other on, in each case subject to
     applicable laws relating to the exchange of information, all the
     information relating to the Company or Parent, 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 Entity
     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 Entities 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.
 
          (c)  Parent and the Company shall, upon request, furnish each other
     with all information concerning themselves, their respective Subsidiaries,
     directors, officers and shareholders and such other matters as may be
     reasonably necessary or advisable in connection with the Proxy Statement,
     the S-4 or any other statement, filing, notice or application made by or on
     behalf of Parent, the Company or any of their respective Subsidiaries to
     any Governmental Entity in connection with the Merger and the other
     transactions contemplated hereby.
 
          (d)  Parent and the Company shall promptly furnish each other with
     copies of written communications received by Parent or the Company, as the
     case may be, or any of their respective Subsidiaries from, or delivered by
     any of the foregoing to, any Governmental Entity in respect of the
     transactions contemplated hereby.
 
     6.02  ACCESS TO INFORMATION.
 
          (a)  Upon reasonable notice and subject to applicable laws relating to
     the exchange of information, the Company shall, and shall cause each of its
     Subsidiaries to, afford to the officers, employees, accountants, counsel
     and other representatives of Parent, 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, the
     Company shall, and shall cause its Subsidiaries to, make available to
     Parent (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 Company is not permitted to
     disclose under applicable law) and (ii) all other information concerning
     its business, properties and personnel as Parent may reasonably request
     (other than information which the Company is not permitted to disclose
     under applicable law).
 
                                       20
<PAGE>   99
 
     Neither the Company nor any of its 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 Company's
     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. Parent will hold
     all such information in confidence to the extent required by, and in
     accordance with, the provisions of the confidentiality agreement, dated
     September 28, 1993, between Parent and the Company (the "Confidentiality
     Agreement").
 
          (b)  Upon reasonable notice and subject to applicable laws relating to
     the exchange of information, Parent shall, and shall cause its Subsidiaries
     to, afford to the officers, employees, accountants, counsel and other
     representatives of the Company, access, during normal business hours during
     the period prior to the Effective Time, to such information regarding
     Parent and its Subsidiaries as shall be reasonably necessary for the
     Company to fulfill its obligations pursuant to this Agreement to prepare
     the Proxy Statement or which may be reasonably necessary for the Company to
     confirm that the representations and warranties of Parent contained herein
     are true and correct and that the covenants of Parent contained herein have
     been performed in all material respects. Neither Parent nor any of its
     Subsidiaries shall be required to provide access to or to disclose
     information where such access or disclosure would violate or prejudice the
     rights of Parent's 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. During the period from the date of this Agreement to the Effective
     Time, Parent will cause one or more of its designated representatives to
     confer on a regular and frequent basis (not less than monthly) with
     representatives of the Company and to report the general status of the
     ongoing operations of Parent and its Subsidiaries.
 
          (c)  All information furnished by Parent to the Company or its
     representatives pursuant hereto shall be treated as the sole property of
     Parent and, if the Merger shall not occur, the Company and its
     representatives shall return to Parent or destroy all of such written
     information and all documents, notes, summaries or other materials
     containing, reflecting or referring to, or derived from, such information.
     The Company shall, and shall use its reasonable efforts to cause its
     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 from the date the proposed Merger is abandoned and shall not
     apply to (i) any information which (x) was already in the Company's
     possession prior to the disclosure thereof by Parent; (y) was then
     generally known to the public; or (z) was disclosed to the Company by a
     third party not bound by an obligation of confidentiality or (ii)
     disclosures made as required by law. It is further agreed that, if in the
     absence of a protective order or the receipt of a waiver hereunder the
     Company is nonetheless, in the opinion of its counsel, compelled to
     disclose information concerning Parent to any tribunal or governmental body
     or agency or else stand liable for contempt or suffer other censure or
     penalty, the Company may disclose such information to such tribunal or
     governmental body or agency without liability hereunder.
 
     6.03  SHAREHOLDER MEETING.  The Company shall take all steps necessary to
duly call, give notice of, convene and hold a meeting of its shareholders to be
held as soon as is reasonably practicable after the date on which the S-4
becomes effective for the purpose of voting upon the approval of this Agreement.
The Company will, through its Board of Directors, recommend to its shareholders
approval of this Agreement and the transactions contemplated hereby and such
other matters as may be submitted to its shareholders in connection with this
Agreement; PROVIDED, HOWEVER, that nothing contained in this Section 6.03 or
elsewhere in this Agreement shall prohibit the Company's Board of Directors from
failing to make such recommendation or modifying or withdrawing its
recommendation, if such Board shall have concluded in good faith with the advice
of counsel that such action is required to prevent such Board from breaching its
fiduciary duties to the shareholders of the Company, and no such action shall
constitute a breach of this Agreement.

     6.04  LEGAL CONDITIONS TO MERGER.  Each of Parent and the Company shall,
and shall cause each of its Subsidiaries to, use its best efforts (a) to take,
or cause to be taken, all actions necessary, proper or advisable to comply
promptly with all legal requirements which may be imposed on such party or its
Subsidiaries with respect to the Merger or the Bank 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 consent, authorization, order or approval of, or any
exemption by, any Governmental Entity and any other third party which is
required to be obtained by the Company or Parent or any of their respective
Subsidiaries in connection with the Merger and the Bank Merger and the other
transactions contemplated by this Agreement. Parent also agrees to accept any
conditions related to savings bank life insurance or the divestiture of the
Company's or the Bank's direct or indirect interests in real estate which are
required by any Regulatory Agency in connection with procuring the regulatory
approvals required to consummate the Merger and the Bank Merger.
 
     6.05  AFFILIATES; PUBLICATION OF COMBINED FINANCIAL RESULTS.
 
          (a)  Each of Parent and the Company shall use all reasonable efforts
     to cause each director, executive officer and other person who is an
     "affiliate" (for purposes of Rule 145 under the Securities Act and for
     purposes of qualifying the Merger for "pooling-of-interests" accounting
     treatment) of such party to deliver to the other party hereto, as soon as
     practicable after the date of this Agreement, and prior to the date of the
     shareholders meeting called by the Company to approve this Agreement, a
     written agreement, in the form of Exhibit 6.05(a) hereto, providing that
     such person will not sell, pledge, transfer or otherwise dispose of any
     shares of Parent Common Stock or Company Common Stock held by such
     "affiliate" and, in the case of the "affiliates" of the Company, the shares
     of Parent Common Stock to be received by such "affiliate" in the Merger:
     (1) in the case of shares of the Company in the Merger, except in
     compliance with the applicable provisions of the Securities Act and the
     rules and regulations thereunder; and (2) during the period commencing 30
     days prior to the Merger and ending at the time of the publication of
     financial results covering at least 30 days of combined operations of
     Parent and the Company.
 
          (b)  Parent shall use its best efforts to publish no later than thirty
     (30) days after the end of the first month after the Effective Time in
     which there are at least thirty (30) days of post-Merger combined
     operations (which month may be the month in which the Effective Time
     occurs), combined sales and net income figures as contemplated by and in
     accordance with the terms of SEC Accounting Series Release No. 135.
 
     6.06  STOCK EXCHANGE LISTING.  Parent shall cause the shares of Parent
Common Stock to be issued in the Merger to be approved for listing on the Stock
Exchange, subject to official notice of insurance, prior to the Effective Time.
 
     6.07  EMPLOYEE BENEFIT PLANS.
 
          (a)  From and after the Effective Time and subject to applicable law,
     the Surviving Corporation and the Surviving Bank shall provide the
     employees of the Company ("Company Employees") with the same benefits
     provided to its own employees; provided, that Parent shall not treat any
     such employee as a "new" employee for purposes of any exclusion for an
     existing condition under any health or similar plan of Parent, the
     Surviving Corporation, or the Surviving Bank. Notwithstanding anything to
     the contrary herein, with respect to benefits payable to employees who
     shall have retired from the Company and its Subsidiaries, whether before
     the Effective Time or after the Effective Time but before December 31,
     1996, the Surviving Corporation and the Surviving Bank shall in no event
     take any action to reduce such benefits and shall take such action as it
     deems appropriate from time to time with respect to possible increases in
     the level of such benefits, taking into consideration among other factors
     any similar increases which Parent shall have effected with respect to its
     retired employees.
 
                                       22
<PAGE>   101
 
          (b)  With respect to the provision of benefits to the Company's
     employees pursuant to Section 6.07(a) hereof, to the extent that Company
     Employees become participants in any employee benefit plans maintained by
     the Surviving Corporation, the Surviving Bank, Parent or any of its
     Subsidiaries ("Parent Plans"), Company Employees shall be credited under
     the Parent Plans for all prior years of service with the Company or any
     Subsidiary of the Company for all purposes to the extent such service was
     recognized by the Company or any Subsidiary of the Company under any of its
     plans.
 
          (c)  The provisions of this Section 6.07 are expressly intended to be
     for the irrevocable benefit of, and shall be enforceable by, each director,
     officer and employee covered hereby and his or her heirs and
     representatives.
 
     6.08  EMPLOYEE TERMINATION AND OTHER BENEFITS.
 
          (a)  Following the Effective Time, Parent shall honor and shall cause
     the Company or any successor thereto to honor in accordance with their
     terms all employment, severance and other compensation agreements and
     arrangements existing prior to the execution of this Agreement, which are
     between the Company or the Bank and any director, officer or employee
     thereof and which have been disclosed in the Company Disclosure Schedule,
     and to assume all duties, liabilities and obligations under such
     agreements. Parent agrees for itself and its Subsidiaries that the
     consummation of the transactions contemplated hereby is a "Change in
     Control" as defined in the Special Termination Agreements entered into
     between the Company and/or the Bank and certain officers as disclosed in
     the Company Reports.
 
          (b)  Parent agrees to offer, or cause the Surviving Bank to offer,
     continued employment on and after the Effective Time to all employees of
     the Company or the Company Subsidiaries who were such immediately prior to
     the Effective Time. Employees of the Company or the Company Subsidiaries
     who are terminated on or within two years after the Effective Time shall be
     provided, in addition to all other applicable benefits, severance and other
     benefits set forth in Section 6.08(b) of the Disclosure Schedule (except
     for Company Employees terminated for engaging in criminal conduct in
     connection with their employment).
 
          (c)  The provisions of this Section 6.08 are expressly intended to be
     for the irrevocable benefit of, and shall be enforceable by, each director,
     officer and employee covered hereby and his or her heirs and
     representatives.
 
     6.09  INDEMNIFICATION; DIRECTORS' AND OFFICERS' 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 the Company 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 Company, any of the Company Subsidiaries or any of their
     respective predecessors or (ii) this Agreement or any of the transactions
     contemplated hereby, 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 the Company shall indemnify and hold harmless and that
     after the Effective Time, the Surviving Corporation and Parent shall
     indemnify and hold harmless, as and to the fullest extent permitted by
     applicable law, each such Indemnified Party against any losses, claims,
     damages, liabilities, costs, expenses (including reasonable attorney's fees
     and expenses), 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
     or arising before or after the Effective Time), (i) the Company, and the
     Surviving Corporation and Parent after the Effective Time, shall promptly
     pay expenses in advance of the final disposition of any claim, suit,
     proceeding or investigation to each Indemnified Party to the full extent
     permitted by law, (ii) the Indemnified Parties may retain counsel
     satisfactory to them, and the Company, and the Surviving
 
                                       23
<PAGE>   102
 
     Corporation and Parent after the Effective Time, shall pay all fees and
     expenses of such counsel for the Indemnified Parties within thirty days
     after statements therefor are received, and (iii) the Company, the
     Surviving Corporation and Parent will use their respective best efforts to
     assist in the vigorous defense of any such matter; provided, that none of
     the Company, the Surviving Corporation or Parent shall be liable for any
     settlement effected without its prior written consent (which consent shall
     not be unreasonably withheld); and provided further, that the Surviving
     Corporation and Parent 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
     non-appealable, 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 6.09, upon
     learning of any such claim, action, suit, proceeding or investigation,
     shall notify the Company and, after the Effective Time, the Surviving
     Corporation and Parent, thereof, provided, that the failure to so notify
     shall not affect the obligations of the Company, the Surviving Corporation
     and Parent, except to the extent such failure to notify materially
     prejudices such party.
 
          (b)  Parent agrees that all rights to indemnification existing in
     favor, and all limitations on the personal liability, of the Indemnified
     Parties provided for in the Company's Certificate of Incorporation or
     By-Laws or the charter or by-laws or similar organizational documents of
     any of its Subsidiaries as in effect as of the date hereof with respect to
     matters occurring prior to the Effective Time shall survive the Merger and
     shall continue in full force and effect for a period of not less than 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 disposition of such Claim.
 
          (c)  Parent shall use its best efforts to cause the persons serving as
     officers and directors of the Company immediately prior to the Effective
     Time to be covered for a period of three years from the Effective Time by
     the directors' and officers' liability insurance policy maintained by the
     Company (provided, that Parent may substitute therefor policies of at least
     the same coverage and amounts containing terms and conditions which are not
     less advantageous than such policy) with respect to acts or omissions
     occurring at or prior to the Effective Time which were committed by such
     officers and directors in their capacity as such; provided, however, that
     in no event shall parent be required to expend more than the amount (the
     "Insurance Amount") equal to 200% of the current amount expended by the
     Company to maintain or procure insurance coverage pursuant hereto, and
     provided further, that if Parent is unable to maintain or obtain the
     insurance called for by this Section 6.09, Parent shall use its best
     efforts to obtain as much comparable insurance as available for the
     Insurance Amount.
 
          (d)  In the event Parent or the Surviving Corporation 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
     proper provision shall be made so that the successors and assigns of Parent
     or the Surviving Corporation, as the case may be, assume the obligations
     set forth in this section.
 
          (e)  The provisions of this Section 6.09 are expressly intended to be
     for the irrevocable benefit of, and shall be enforceable by, each
     Indemnified Party and his or her heirs and representatives.
 
     6.10  SUBSEQUENT INTERIM AND ANNUAL FINANCIAL STATEMENTS.  As soon as
reasonably available, but in no event later than April 1, 1994, Parent will
deliver to the Company and the Company will deliver to Parent their respective
Annual Reports on Form 10-K for the fiscal year ended December 31, 1993, as
filed with the SEC under the Exchange Act. As soon as reasonably available, but
in no event more than 45 days after the end of each fiscal quarter ending after
the date of this Agreement, Parent will deliver to the Company and the Company
will deliver to Parent their respective Quarterly Reports on Form 10-Q, as filed
with the SEC under the Exchange Act.
 
     6.11  ADDITIONAL AGREEMENTS.  In case at any time after the Effective Time
any further action is necessary or desirable to carry out the purpose of this
Agreement, or the Bank Merger Agreement, or to vest the Surviving Corporation or
the Surviving Bank with full title to all properties, assets, rights, approvals,
 
                                       24

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, Parent.
 
     6.12  DISCLOSURE SUPPLEMENTS.  From time to time prior to the Effective
Time, each party will promptly supplement or amend the Disclosure Schedules
delivered in connection with the execution of this Agreement 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 such Disclosure
Schedules or which is necessary to correct any information in such Disclosure
Schedules which has been rendered inaccurate thereby. No supplement or amendment
to such Disclosure Schedules shall have any effect for the purposes of
determining satisfaction of the conditions set forth in Sections 7.02(a) or
7.03(a) hereof, as the case may be, or the compliance by the Company or Parent,
as the case may be, with the respective covenants set forth in Sections 5.01 and
5.04 hereof.
 
     6.13  CURRENT INFORMATION.
 
          (a)  During the period from the date of this Agreement to the
     Effective Time, the Company will cause one or more of its designated
     representatives to be available to confer on a regular and frequent basis
     (not less than monthly) with representatives of Parent and to report the
     general status of the ongoing operations of the Company and its
     Subsidiaries. The Company will promptly notify Parent of any material
     change in the normal course of business of the Company or any of its
     Subsidiaries and of any governmental complaints, investigations or hearings
     or the institution of significant litigation involving the Company or any
     of its Subsidiaries and will keep Parent reasonably informed of such
     events.

     the normal course of business of Parent or any of its Subsidiaries and of
     any governmental complaints, investigations or hearings, or the institution
     of significant litigation involving Parent or any of its Subsidiaries, and
     will keep the Company reasonably informed of such events.

     the Company under any loan or credit agreement, note, mortgage, indenture,
     lease, license or other agreement or instrument shall have been obtained,

     Goodwin, Procter & Hoar, counsel to the Company, dated the Closing Date,

     shall not become exercisable for capital stock of Parent upon consummation
     of the Merger.
 
     7.03  CONDITIONS TO OBLIGATIONS OF THE COMPANY.  The obligation of the
Company to effect the Merger is also subject to the satisfaction or waiver by
the Company at or prior to the Effective Time of the following conditions:
 
          (a)  REPRESENTATIONS AND WARRANTIES.  The representations and
     warranties of Parent set forth in this Agreement shall be true and correct
     in all material respects as of the date of this Agreement and (except to

     provided, however, that, for purposes hereof, such representations and

     unless the failure or failures of such representations and warranties to be
     so true and correct, without giving effect to any exception in such
     representations and warranties relating to materiality, represent, in the
     aggregate, a Material Adverse Effect (as defined in Section 3.01 hereof).

     the Chief Executive Officer and the Chief Financial Officer of Parent to
     the foregoing effect.
 
          (b)  PERFORMANCE OF OBLIGATIONS OF PARENT.  Parent shall have each
     performed in all material respects all obligations required to be performed
     by it under this Agreement at or prior to the Closing Date, and the Company

     transactions contemplated hereby under any loan or credit agreement, note,
     mortgage, indenture, lease, license or other agreement or instrument to
     which Parent or any of its Subsidiaries is a party or is otherwise bound,
     except those for which failure to obtain such consents and approvals would
     not have a Material Adverse Effect on Parent and its Subsidiaries taken as
     a whole (after giving effect to the transactions contemplated hereby).
 
          (d)  FEDERAL TAX OPINION.  The Company shall have received from its
     counsel, opinions dated as of the Effective Time, in form and substance
     reasonably satisfactory to the Company, rendered on the basis of facts,
     representations, and assumptions set forth in such opinions or in writing
     elsewhere and referred to therein, substantially to the effect that for
     federal income tax purposes (i) the Merger constitutes a reorganization
     within the meaning of Section 368(a) of the Code, and (ii) accordingly no
     gain or loss will be recognized by shareholders of the Company with respect
     to Parent Common Stock received solely in exchange for Company Common Stock
     pursuant to this Agreement (noting, however, that nontaxability does not
     extend to cash received in lieu of a fractional shares interest in Parent
     Common Stock or to cash received by dissenters, if any). In rendering any
     such opinion, such counsel may require and, to the extent they deem
     necessary or appropriate may rely upon, opinions of other counsel and upon
     representations made in certificates of officers of the Company, Parent,
     affiliates of the foregoing, and others.
 
          (e)  LEGAL OPINION.  The Company shall have received the opinion of
     Edwards & Angell, counsel to Parent, dated the Closing Date, substantially
     in the form attached hereto as Exhibit 7.03(e). As to any matter in such
     opinion which involves matters of fact or matters relating to laws other
     than Federal securities law, Rhode Island law or Delaware corporate law,
     such counsel may rely upon the certificates of officers and directors of
     Parent and of public officials and opinions of local counsel, reasonably
     acceptable to the Company.

     treatment.
 
          (g)  OPINION OF FINANCIAL ADVISOR.  The Company shall have received an
     opinion, dated as of the date of the Proxy Statement, from Keefe, Bruyette
     & Woods to the effect that as of the date thereof the consideration to be
     received by the shareholders of the Company pursuant to the Merger is fair
     to such shareholders from a financial point of view.

     8.01  TERMINATION.  This Agreement may be terminated at any time prior to
the Effective Time, whether before or after approval of the matters presented in
connection with the Merger by the shareholders of the Company:
 
          (a)  by mutual consent of Parent and the Company 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 Parent or the Company upon written notice to the other
     party (i) forty-five days after the date on which any request or
     application for a regulatory approval required to consummate the Merger
     shall have been denied or withdrawn at the request or recommendation of the
     Governmental Entity which must grant such requisite regulatory approval,
     unless within the forty-five day period following such denial or withdrawal
     a petition for rehearing or an amended application has been filed with the
     applicable Governmental Entity, provided, however, that no party shall have
     the right to terminate this Agreement pursuant to this Section 8.01(b)(i)
     if such denial or request or recommendation for withdrawal 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, or
     (ii) if any Governmental Entity of competent jurisdiction shall have issued
     a final nonappealable order enjoining or otherwise prohibiting the
     consummation of any of the transactions contemplated by this Agreement;
    
 
          (c)  by either Parent or the Company if the Merger shall not have been
     consummated on or before September 30, 1994, 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 in any material
     respect the covenants and agreements of such party set forth herein;
 
          (d)  by either Parent or the Company (provided, that if the
     terminating party is the Company, the Company shall not be in material
     breach of any of its obligations under Section 6.03) if any approval of the
     shareholders of the Company 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 shareholders or at any adjournment
     or postponement thereof;
 
          (e)  by either Parent or the Company (provided, that the terminating
     party is not then in material breach of any representation, warranty,
     covenant or other agreement contained herein) if there shall have been a
     material breach of any of the representations or warranties set forth in
     this Agreement on the part of the other party, which breach is not cured
     within forty-five days following written notice to the party committing
     such breach, or which breach, by its nature, cannot be cured prior to the
     Closing;
 
          (f)  by either Parent or the Company (provided, that the terminating
     party is not then in material breach of any representation, warranty,
     covenant or other agreement contained herein) if there shall have been a
     material breach of any of the covenants or agreements set forth in this
     Agreement on the part of the other party, which breach shall not have been
     cured within forty-five days following receipt by the breaching party of
     written notice of such breach from the other party hereto; or
 
          (g)  by the Company, whether before or after approval of the Merger by
     the shareholders of the Company, by giving written notice of such election
     to Parent, in the event that the Average Closing Price
 
                                       28
<PAGE>   107
 
   
     is equal to or less than $25.59, unless Parent provides written notice to
     the Company, by the twelfth business day after the date on which the last
     of the regulatory approvals required to consummate the transactions
     contemplated hereby is obtained, of its election to adopt the Adjusted
     Maximum Exchange Ratio as the Exchange Ratio.
    
 
     8.02  EFFECT OF TERMINATION; EXPENSES.
 
          (a)  In the event of termination of this Agreement by either Parent or
     the Company as provided in Section 8.01, this Agreement shall forthwith
     become void and have no effect except (i) the last sentence of Section
     6.02(a), and Sections 6.02(c), 8.02 and 9.03, shall survive any termination
     of this Agreement, and (ii) notwithstanding anything to the contrary
     contained in this Agreement, no party 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, expenses of the parties hereto
     shall be determined as follows:
 
             (i)  Any termination of this Agreement pursuant to Section 8.01(a)
        or Section 8.01(d) hereof shall be without cost, expense or liability on
        the part of any party to the other. Any termination of this Agreement
        pursuant to Section 8.01(e) or Section 8.01(f) hereof shall also be
        without cost, liability or expense on the part of any party to the
        others, unless the breach of a representation or warranty or the breach
        of a covenant is caused by the willful conduct or gross negligence of a
        party in which event said party shall be liable to the other party for
        all out-of-pocket costs and expenses, including, without limitation,
        reasonable legal, accounting and investment banking fees and expenses,
        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").
 
             (ii)  If this Agreement is terminated pursuant to Section 8.01(b)
        or Section 8.01(c) or the transactions contemplated hereby otherwise
        fail to be consummated, in any such case because of the failure to
        receive any required regulatory approval, Parent shall reimburse the
        Company for all Expenses up to a maximum of $1,000,000.
 
             (iii)  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 and notwithstanding anything to the contrary
        contained herein, no party shall be relieved or released from any
        liabilities or damages arising out of its willful breach of any
        provisions of this Agreement.
 
     8.03  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 the Merger by the shareholders of the
Company; provided, however, that after any approval of the transactions
contemplated by this Agreement by the Company's shareholders, there may not be,
without further approval of such shareholders, any amendment of this Agreement
which reduced the amount or changes the form of the consideration to be
delivered to the Company's shareholders hereunder 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.
 
     8.04  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 Company's shareholders, there may not be, without further approval of such
shareholders, 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 Company's shareholders 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 shall not operate
as a waiver of, or estoppel with respect to, any subsequent or other failure.

                             STOCK OPTION AGREEMENT
 
     STOCK OPTION AGREEMENT, dated as of October 11, 1993, between Sterling
Bancshares Corporation ("Issuer") and Fleet Financial Group, Inc. ("Grantee").
 
     WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of
Merger of even date herewith ("Merger Agreement"), which agreement is being
executed by the parties hereto simultaneously with this Agreement; and
 
     WHEREAS, as a condition to Grantee's entry into the Merger Agreement and in
consideration for such entry, 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 512,943
fully paid and nonassessable shares (the "Option Shares") of common stock, par
value $.10 per share ("Common Stock"), of Issuer at a price of $30.50 per share
(the "Option Price"). 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 provided that in no event shall the number of shares for
which this Option is exercisable exceed 17.0% of the Issuer's issued and
outstanding shares of Common Stock (without giving effect to any shares of
Common Stock subject to or issued pursuant to the Option) less the number of
shares previously issued pursuant to exercise of the Option.
 
     (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 exercise of the Option pursuant to this Agreement or as contemplated
by Section 5(a)(i) of this Agreement), including, without limitation, pursuant
to stock option or other employee plans or as a result of the exercise of
conversion rights, the number of shares of Common Stock subject to the Option
shall be increased so that, after such issuance, such number equals 17.0% of the
number of shares of Common Stock then issued and outstanding without giving
effect to any shares subject to 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, 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 (f) of this Section (2)
within 30 days following such Subsequent Triggering Event.
 
     (b)  The term "Exercise Termination Event" shall mean (i) the Effective
Time of the Merger, (ii) termination of the Merger Agreement in accordance with
the provisions thereof if such termination occurs prior to the occurrence of an
Initial Triggering Event; (iii) termination of the Merger Agreement in
accordance with the provisions thereof if such termination occurs after the
occurrence of an Initial Triggering Event, except in the case of termination of
the Merger Agreement based on the provisions of Section 8.01(d) if the Grantee
or the Issuer terminates, the passage of 6 months after termination, or in the
case of termination of the Merger Agreement based on the provisions of Section
8.01(e) or (f), if the Grantee terminates, the passage of 6 months after
termination, or in the case of termination of the Merger Agreement based on the
provisions of Section 8.01(e) or (f), if the Issuer terminates, immediately.
Notwithstanding the termination of the Option, Grantee shall be entitled to
purchase those Option Shares with respect to which it has exercised the Option
in whole or in part prior to the termination of the Option.
 
     (c)  The term "Holder" shall mean the holder of the Option. The term
"Schedule 13G Investor" shall mean either (i) any person holding voting
securities of the Issuer eligible to report the beneficial ownership of such
securities on Schedule 13G pursuant to the provisions of Rule 13d-1 under the
Exchange Act or (ii) any Person holding voting securities of the Issuer who is
required to report the beneficial ownership of such securities on Schedule 13D
pursuant to the provisions of Rule 13d-1 under the Exchange Act and who
<PAGE>   112
 
indicates in such Schedule 13D that such Person has acquired such securities for
passive investment purposes and not with the purpose nor with the effect of
changing or influencing the control of the Issuer nor in connection with or as a
participant in any transaction having such purpose or effect.
 
     (d)  The term "Initial Triggering Event" shall mean any of the following
events or transactions occurring after the date hereof:
 
          (i)  Issuer or any Subsidiary of Issuer, without having received
     Grantee's prior written consent, shall have entered into an agreement to
     engage in an Acquisition Transaction 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 Exchange Act and the rules and regulations
     thereunder), other than Grantee or any Subsidiary of Grantee, or, without
     the consent of the Grantee, the Board of Directors of Issuer shall have
     approved an Acquisition Transaction or recommended that the shareholders of
     Issuer approve or accept any Acquisition Transaction other than as
     contemplated by the Merger Agreement. For purposes of this Agreement, the
     term "Acquisition Transaction" shall mean (x) a merger or consolidation, or
     any similar transaction, with Issuer or any Subsidiary of Issuer, (y) a
     purchase, lease or other acquisition of all or substantially all of the
     assets of Issuer or any Subsidiary of Issuer or (z) 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 Subsidiary of Issuer.
 
          (ii)  Any person, other than Grantee or any Subsidiary of Grantee or
     other than Issuer or any Subsidiary of Issuer and other than a Schedule 13G
     Investor, shall have acquired 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 in the rules and
     regulations thereunder) or the right to acquire beneficial ownership of 10%
     or more of the outstanding shares of Common Stock if such person
     beneficially owned less than 10% of the outstanding shares of Common Stock
     on the date of this Agreement, or any person shall have acquired beneficial
     ownership of an additional 3% of the outstanding shares of Common Stock if
     such person beneficially owned 10% or more of the outstanding shares of
     Common Stock on the date of this Agreement;
 
          (iii)  Any person, other than Grantee or any Subsidiary of Grantee,
     shall have made a bona-fide proposal to Issuer or its shareholders to
     engage in an Acquisition Transaction by public announcement or written
     communication that shall be or become the subject of public disclosure; or
 
          (iv)  After any person other than Grantee or any Subsidiary of Grantee
     has made a proposal to Issuer or its shareholders 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 remedied prior to the Notice Date (as defined below).
 
     (e)  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 other than a Schedule 13G Investor
     of beneficial ownership of 15% or more of the then outstanding Common
     Stock; or
 
          (ii) The occurrence of the Initial Triggering Event described in
     clause (i) of subsection (d) of this Section 2, except that the percentage
     reference in clause (z) shall be 15%.
 
     (f)  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.
 
     (g)  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 is 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"); provided that if prior
notification to or approval of the Federal Reserve Board or any other
 
                                        2
<PAGE>   113
 
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 have expired or been terminated or such approvals have been
obtained and any requisite waiting period or periods shall have passed.
 
     (h)  At the Closing, 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 a 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.
 
     (i)  At such Closing, simultaneously with the delivery of immediately
available funds as provided in subsection (h) 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.
 
     (j)  Certificates for the Common Stock delivered at a closing hereunder may
(in the sole discretion of the Issuer) be endorsed with a restrictive legend
that shall read substantially as follows:
 
     "THE TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO
     RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND
     PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF OCTOBER 11,
     1993, A COPY OF WHICH AGREEMENT WILL BE PROVIDED TO THE HOLDER HEREOF
     WITHOUT CHARGE UPON RECEIPT BY THE ISSUER OF A WRITTEN REQUEST THEREFOR."
 
It is understood and agreed that (i) the reference to the resale restrictions of
the Securities 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 Securities and
Exchange Commission, 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 Securities Act; (ii) the reference to the provisions of 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.
 
     (k)  Upon the giving by the Holder to Issuer of the written notice of
exercise of the Option provided for under subsection (g) of this Section 2, the
tender of the applicable purchase price in immediately available funds and the
tender of a copy of this Agreement to Issuer, such 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 by Issuer under this Section 2 in the name of the Holder or its
assignee, transferee or designee.
 
     3.  Issuer agrees (a) 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, (b)
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
 
                                        3
<PAGE>   114
 
   
hereunder by Issuer, (c) 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) cooperating fully with any Holders in preparing
any applications or notices required under the Bank Holding Company Act of 1956,
as amended, or the Change in Bank Control Act of 1978, as amended, or any state
banking law), in order to permit such Holders to exercise the Option and the
Issuer duly and effectively to issue shares of Common Stock pursuant hereto, and
(d) promptly to take all action provided herein to protect the rights of any
Holders against dilution.
    
 
   
     4.  This Agreement (and the Option granted hereby) is 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.
    
 
     5.  In addition to the adjustment in the number of Option Shares pursuant
to Section 1 of this Agreement, the number of Option Shares shall be subject to
adjustment from time to time as provided in this Section 5.
 
          (a)(i)  In the event of any change in the shares of Common Stock by
     reason of stock dividend, split-up, merger, recapitalization, subdivision,
     conversion, combination, exchange of shares or similar transaction, the
     type and number of Option Shares shall be adjusted so that Grantee shall
     receive upon exercise of the Option the number and class of shares or other
     securities or property that Grantee would have held immediately after such
     event if the Option had been exercised immediately prior to such event, or
     the record date therefor, as applicable. The term "Option Shares" shall
     include any such shares or other securities or property issued or issuable
     upon exercise of the Option.
 
          (a)(ii)  Issuer may make such increases in the number of Option
     Shares, in addition to those required under subsection (a)(i), as shall be
     determined by its Board of Directors to be advisable in order to avoid
     taxation, so far as practicable, of any dividend of stock or stock rights
     or any event treated as such for Federal income tax purposes to the
     recipients.
 
          (b)  Whenever the number of Option Shares purchasable upon exercise
     hereof is adjusted as provided in this Section 5, the Option Price shall be
     adjusted by multiplying the Option Price by a fraction, the numerator of
     which is equal to the number of Option Shares prior to the adjustment and
     the denominator of which is equal to the number of Option Shares (or other
     securities) purchasable after the adjustment.
 
     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 30 days of such Subsequent Triggering Event, promptly prepare,
file and keep current, with respect to the Option Shares, a "shelf" registration
statement under Rule 415 of the Securities Act or any successor provision, and
Issuer shall use its best efforts to qualify such Option Shares under any
applicable state securities laws. Issuer will use its best efforts to cause such
registration statement first to become effective and then to remain effective
for each 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 sales or other dispositions of the Option Shares. 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 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 Option Shares would interfere with the successful marketing of the shares of
Common Stock offered by Issuer
 
                                        4
<PAGE>   115
 
in such underwritten public offering, the number of Option Shares otherwise to
be covered in the registration statement contemplated hereby may be reduced;
provided, however, that if such reduction occurs, 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 Option 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.
 
     7.  (a)  Upon the occurrence of a Subsequent Triggering Event that occurs
prior to an Exercise Termination Event, (i) at the request of any Holder,
delivered within 30 days of such occurrence (or such later period as provided in
Section 10), Issuer 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, plus, to the extent not
previously reimbursed, Grantee's reasonable out-of-pocket expenses incurred in
connection with the transactions contemplated by the Merger Agreement, including
without limitation legal, accounting and investment banking fees (the "Grantee's
Out-of-Pocket Expenses") and (ii) at the request of any owner of Option Shares
from time to time (the "Owner"), delivered within 30 days of such occurrence (or
such later period as provided in Section 10), Issuer shall repurchase such
number of the Option Shares from such Owner as the Owner shall designate at a
price per share ("Option Share Repurchase Price") equal to the greater of (A)
the market/offer price and (b) the average exercise price per share paid by
Owner for the Option Shares so designated, plus the Grantee's Out-of-Pocket
Expenses. The term "market/offer price" shall mean the highest of (w) the price
per share of the Common Stock at which a tender offer or exchange offer therefor
has been made, (x) the price per share of the Common Stock to be paid by any
person, other than Grantee or a Subsidiary of Grantee, pursuant to an agreement
with Issuer, (y) 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 (z) in the event of a sale
of all or substantially all 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 a majority in interest of the Holders or Owners, as the case may be,
and reasonably acceptable to the Issuer, 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 a
majority in interest of the Holders or Owners, as the case may be, and
reasonably acceptable to the Issuer.
 
     (b)  Each Holder and 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 such Holder or Owner
elects to require Issuer to repurchase this Option and/or Option Shares in
accordance with the provisions of this Section 7. As promptly as practicable,
and in any event within 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, Issuer shall deliver or cause to be delivered to each
Holder the Option Repurchase Price and/or to each 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, or as a consequence of administrative policy, or as a result of a
written agreement or other binding obligation with a governmental or regulatory
body or agency, from repurchasing the Option and/or the Option Shares in full,
Issuer shall immediately so notify each Holder and/or each Owner and thereafter
deliver or cause to be delivered, from time to time, to such Holder and/or
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
 
                                        5
<PAGE>   116
 
applicable law or regulation, or as a consequence of administrative policy, from
delivering to any Holder and/or Owner, as appropriate, the Option Repurchase
Price and the Option Share Repurchase Price, respectively, in part or in full
(and Issuer hereby undertakes to use its best efforts to receive all required
regulatory and legal approvals and to file any required notices as promptly as
practicable in order to accomplish such repurchase), such 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 Issuer shall promptly (i)
deliver to such Holder and/or Owner, as appropriate, that portion of the Option
Purchase Price or the Option Share Repurchase Price that Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (A) to such
Holder, a new Stock Option Agreement evidencing the right of such Holder to
purchase that number of Option Shares 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 such Owner, a certificate for the
Option Shares it is then so prohibited from repurchasing.
 
     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 Grantee's Subsidiaries, and Issuer 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 shares and
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 Grantee's 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 (y) the Acquiring Corporation
(as hereinafter defined) or (z) any person that controls the Acquiring
Corporation.
 
     (b)  The following terms have the meanings indicated:
 
          (i)  The term "Acquiring Corporation" shall mean (A) the continuing or
     surviving corporation of a consolidation or merger with Issuer (if other
     than Issuer), (B) the Issuer in a merger in which Issuer is the continuing
     or surviving person, and (C) the transferee of all or substantially all of
     Issuer's assets.
 
          (ii)  The term "Substitute Common Stock" shall mean the common stock
     issued by the issuer of the Substitute Option upon exercise of the
     Substitute Option.
 
          (iii)  The term "Assigned Value" shall mean the "market/offer price",
     as defined in Section 7.
 
          (iv)  The term "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 the 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 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, to the extent legally permissible,
be as similar as possible to, and in no event less advantageous to the Holder
than, the terms of the Option. The issuer of the Substitute Option shall also
enter into an agreement with the then Holder 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 the 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 the Substitute Common Stock shall then be equal to the Option Price
multiplied by a fraction in which the numerator is the number of Option Shares
and the denominator is the number of shares of the 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 17.0% of the aggregate of the
shares of the Substitute Common Stock outstanding prior to exercise of the
Substitute Option (without giving effect to any shares of Substitute Common
Stock issued pursuant to the Substitute Option) less the number of shares
previously issued pursuant to the Substitute Option. In the event that the
Substitute Option would be exercisable for more than 17.0% 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). The difference in value shall be determined by a nationally
recognized investment banking firm selected by the Holder, as the case may be.
 
     (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 shall have assumed 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 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 the Substitute Common Stock for which the Substitute
Option may then be exercised, plus the Grantee's Out-of-Pocket Expenses, and at
the request of each owner (the "Substitute Share Owner") of shares of the
Substitute Common Stock (the "Substitute Shares"), the Substitute Option Issuer
shall repurchase the Substitute Shares at a price per share (the "Substitute
Share Repurchase Price") equal to the greater of (y) the Highest Closing Price
and (z) the average exercise price per share paid by the Substitute Share Owner
for the Substitute Shares so designated plus Grantee's Out-of-Pocket Expenses.
The term "Highest Closing Price" shall mean the highest closing price for shares
of the 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)  Each 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 such
Substitute Option Holder or Substitute Share Owner elects to require the
Substitute Option Issuer to repurchase the Substitute Option and/or the
Substitute Shares in accordance with the provisions if this Section 9. As
promptly as practicable, and in any event within five business days after the
surrender of the Substitute Option and/or the 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(s) 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, or as a consequence of administrative policy, or
as a result of a written agreement or other binding obligation with a
governmental or regulatory body or agency, from repurchasing the Substitute
Option and/or the Substitute Shares in full, the Substitute Option Issuer shall
immediately so notify each 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 Substitute Share Owner, as appropriate, that
portion of the Substitute
 
                                        7
<PAGE>   118
 
Option Repurchase Price and 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, or as a consequence of
administrative policy, or as a result of a written agreement or other binding
obligation with a governmental or regulatory body or agency, 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 part or 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 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 30-day period for exercise of certain rights under Section 2, 6, 7
and 12 hereof shall be extended in each such case: (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 Exchange Act by reason of such
exercise; provided that notice of intent to exercise such rights shall be given
to Issuer within the requisite 30-day period and Grantee and Holders shall use
their best efforts to promptly obtain all requisite approvals and cause the
expiration of all requisite waiting periods; and further provided that no
further extension shall be made with respect to any requlatory approval which
shall have been denied pursuant to a final, unappealable action by the
regulatory authority from which such approval was sought.
 
     11.  Issuer hereby represents and warrants to Grantee as follows:
 
          (a)  Issuer has full corporate power and authority to execute and
     deliver this Agreement. The execution and delivery of this Agreement 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. This Agreement has been duly and validly executed
     and delivered by Issuer.
 
          (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, encumbrances and security interests and not subject to
     any preemptive rights.
 
     12.  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.
 
     13.  If at any time after the occurrence of a Subsequent Triggering Event
and, with respect to shares of Common Stock or other securities acquired by the
Grantee pursuant to an exercise of the Option, prior to the expiration of 24
months after the expiration of the Option pursuant to Section 2(b), Grantee
shall desire to sell, assign, transfer or otherwise dispose of the Option, in
whole or in part, or of all or any of the shares of Common Stock or other
Securities acquired by Grantee pursuant to the Option, Grantee shall give Issuer
 
                                        8
<PAGE>   119
 
written notice of the proposed transaction (the "Offeror's Notice"), identifying
the proposed transferee and setting forth the terms of the proposed transaction.
An Offeror's Notice shall be deemed an offer by Grantee to Issuer, which may be
accepted within ten business days of the receipt of such Offeror's Notice, on
the same terms and conditions and at the same price at which Grantee is
proposing to transfer the Option or such shares or securities to such
transferee. The purchase of the Option or such shares or other securities by
Issuer shall be settled within 5 business days of the date of acceptance of the
offer and the purchase price shall be paid to the Grantee in immediately
available funds; provided that, if prior notification to or approval, consent or
waiver of the Federal Reserve Board or any other regulatory authority is
required in connection with such purchase, Issuer shall promptly file the
required notice or application for approval, consent or waiver and shall
expeditiously process the same (and Grantee shall cooperate with Issuer in the
filing of any such notice or application and the obtaining of any such approval)
and the period of time that otherwise would run pursuant to this sentence shall
run instead from the date on which, as the case may be, (a) the required
notification period has expired or been terminated or (b) such approval has been
obtained and, in either event, any requisite waiting period shall have passed.
In the event of the failure or refusal of Issuer to purchase the Option or the
shares or other securities, as the case may be, covered by the Offeror's Notice
or if the Federal Reserve Board or any other regulatory authority disapproves
Issuer's proposed purchase of the Option or such shares or other securities,
Grantee may, within 60 days from the date of the Offeror's Notice (subject to
any necessary extension for regulatory notification, approval or waiting
periods), sell all, but not less than all, of the portion of the Option (which
may be 100%) or such shares or other securities, as the case may be, proposed to
be transferred to the proposed transferee identified in the Offeror's Notice at
no less than the price specified and on terms no less favorable to the proposed
transferee than those set forth in the Offeror's Notice. The requirements of
this Section 13 shall not apply to (i) any disposition of the Option or any
shares of Common Stock or securities by a Person to whom Grantee has assigned
its rights under the Option with the prior written consent of the Issuer, (ii)
any sale by means of a public offering registered under the Securities Act in
which steps are taken to reasonably ensure that no purchaser will acquire
securities representing more than 2% of the outstanding shares of Common Stock
of the Issuer or (iii) any transfer of a direct or indirect wholly-owned
subsidiary of Grantee who agrees in writing to be bound by the terms hereof.
 
     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 applying to the Federal Reserve
Board under the Bank Holding Company Act for approval to acquire the shares
issuable hereunder.
 
     15.  Notwithstanding anything to the contrary herein, in the event that the
Holder or any Related Person thereof (as hereinafter defined) is a person making
an offer or proposal to engage in an Acquisition Transaction (other than the
transaction contemplated by the Merger Agreement), then (i) in the case of a
Holder or any Related Person thereof, the Option held by it shall immediately
terminate and be of no further force or effect. For purposes of this Agreement,
a Related Person of a Holder means any Affiliate (as defined in Rule 12b-2 of
the rules and regulations under the Exchange Act) of the Holder and any person
that is required to file a Schedule 13D with the Holder with respect to shares
of Common Stock or options to acquire the Common Stock.
 
     16.  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 hereto shall be enforceable by either party hereto
through injunctive or other equitable relief.
 
     17.  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 of 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.

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.
 
     19.  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.
 
     20.  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.
 
     21.  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.
 
     22.  Except as otherwise expressly provided herein, 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. Nothing in this
Agreement, express or implied, is intended to confer upon any party, other than
the parties hereto, and their respective successors and permitted assigns, any
rights, remedies, obligations or liabilities under or by reason of this
Agreement, except as expressly provided herein.
 
     23.  Capitalized terms used in this Agreement and not defined herein shall
have the meanings assigned thereto in the Merger Agreement, provided that
references to "Subsidiaries" or "Grantee" and "Issuer" shall be deemed to refer
to Subsidiaries (as defined in the Merger Agreement) of Grantee and Issuer,
respectively.
 
     IN WITNESS WHEREOF, each of the parties has caused this Agreement to be
executed as a sealed instrument on its behalf by its officers thereunder duly
authorized, all as of the day and year first above written.

The Board of Directors
Sterling Bancshares Corporation
One Moody Street
Waltham, Massachusetts 02154
 
Members of the Board:
 
   
     You have requested our opinion as investment bankers as to the fairness
from a financial point of view, to the holders of the outstanding shares of
Common Stock, par value $.10 per share (the "Common Shares") of Sterling
Bancshares Corporation ("Sterling") of the Exchange Ratio, as hereinafter
defined, with respect to the shares of Common Stock, par value $.01 per share
(the "Fleet Common Stock"), of Fleet Financial Group, Inc. ("Fleet") to be
received for each Common Share in the proposed merger ("Merger") of Sterling
with and into Fleet pursuant to the Agreement and Plan of Merger dated as of
October 11, 1993 (the "Agreement"). Under the terms of the Agreement, the
Exchange Ratio will be determined by dividing $39.50 by the average closing
price of Fleet Common Stock (the "Average Closing Price") as reported by The New
York Stock Exchange (the "Stock Exchange") for the twenty Stock Exchange trading
days ending on the tenth business day after the date on which the last of the
regulatory approvals required is obtained; provided, that (i) if the Average
Closing Price is equal to or greater than $39.24, the Exchange Ratio will be
1.0066, (ii) if the Average Closing Price is equal to or less than $29.01, the
Exchange Ratio will be 1.3616, and (iii) if the Average Closing Price is equal
to or less than $25.59, Sterling shall have the right, waivable by it, to
terminate the Agreement unless Fleet elects, at its option, to adopt the
Exchange Ratio determined by dividing $34.84 by the Average Closing Price.
    
 
     Keefe, Bruyette & Woods, Inc. as part of its investment banking business,
is continually engaged in the valuation of bank and bank holding company
securities in connection with acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for various other purposes. As specialists in the securities of
banking companies, we have experience in, and knowledge of, the valuation of
banking enterprises. In the ordinary course of our business as a broker-dealer,
we may, from time to time, purchase securities from, and sell securities to,
Sterling and Fleet and as a market maker in securities we may from time to time
have a long or short position in, and buy or sell, debt or equity securities of
Sterling and Fleet for our own account and for the accounts of our customers. To
the extent we have any such position as of the date of this opinion it has been
disclosed to Sterling. We have acted exclusively for the Board of Directors of
Sterling in rendering this fairness opinion and will receive a fee from Sterling
for our services.
 
     In arriving at our opinion, we have reviewed, analyzed and relied upon
material bearing upon the financial and operating condition of Sterling and
Fleet, including, among other things, the following: (i) the Agreement; (ii) the
Registration Statement on Form S-4 filed by Fleet to register the shares of its
common stock to be issued in the Merger; (iii) Annual Reports to Shareholders
and Annual Reports on Form 10-K for the three years ended December 31, 1992 of
Sterling and Fleet; (iv) certain interim reports to shareholders of Sterling and
Fleet and Quarterly Reports on Form 10-Q of Sterling and Fleet to their
respective shareholders; (v) other financial information concerning the
businesses and operations of Sterling and Fleet furnished to us by Sterling and
Fleet for purposes of our analysis, including certain internal financial
analyses and forecasts for Sterling and Fleet prepared by the senior management
of Sterling and Fleet; (vi) plans of the combined company and the strategic
objectives of the Merger with the senior executives of Sterling and Fleet;

Board of Directors
Sterling Bancshares Corporation
   
February   , 1994
    
 
(vii) certain publicly available information concerning the trading of, and the
trading market for, the common stock of Sterling and Fleet; and (viii) certain
publicly available information with respect to banking companies and the nature
and terms of certain other transactions that we consider relevant to our
inquiry.
 
     In conducting our review and arriving at our opinion, we have relied upon
and assumed the accuracy and completeness of all of the financial and other
information provided to us or publicly available and we have not attempted
independently to verify such information. We have relied upon the management of
Sterling and Fleet as to the reasonableness and achievability of the financial
and operating forecasts and projections (and the assumptions and bases therefor)
provided to us, and we have assumed that such forecasts and projections reflect
the best currently available estimates and judgements of such managements and
that such forecasts and projections will be realized in the amounts and in the
time periods currently estimated by such managements. We have also assumed,
without independent verification, that the aggregate allowances for loan losses
for Sterling and Fleet are adequate to cover such losses. We have not made or
obtained any evaluations or appraisals of the property of Sterling or Fleet, nor
have we examined any individual loan credit files. Finally, you have informed us
and we have assumed that the Merger will be recorded as a pooling of interests
under generally accepted accounting principles.
 
     We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including among others the following: (i)
the historical and current financial position, results of operations and assets
and liabilities of Sterling and Fleet; and (ii) the nature and terms of certain
other merger transactions involving banks and bank holding companies. We have
also taken into account our assessment of general economic, market and financial
conditions and our experience in other transactions, as well as our experience
in securities valuation and our knowledge of the banking industry generally. Our
opinion is necessarily based upon conditions as they exist and can be evaluated
on the date hereof and the information made available to us through the date
hereof.
 
     Based upon and subject to the foregoing, we are of the opinion that, as of
the date hereof, the Exchange Ratio in the Merger is fair, from a financial
point of view, to the holders of the Common Shares.
 
                                          Very truly yours,

        Re: Federal Income Tax Consequences of Proposed Merger of Sterling
            Bancshares Corporation with and into Fleet Financial Group, Inc.
            ----------------------------------------------------------------

Ladies and Gentlemen:

        We have acted as special counsel to Sterling Bancshares Corporation
("Sterling") in connection with the proposed merger (the "Merger") of Sterling
with and into Fleet Financial Group, Inc. ("Fleet") pursuant to an Agreement and
Plan of Merger dated as of October 11, 1993 (the "Merger Agreement") by and
between Sterling and Fleet, whereby Fleet will acquire all of the assets of
Sterling, including the stock of Sterling Bank, a Massachusetts-chartered stock
savings bank and wholly-owned subsidiary of Sterling ("Sterling Bank"), as
described more fully in the Registration Statement on Form S-4 of Fleet (the
"Registration Statement") filed with the Securities and Exchange Commission
under the Securities Act of 1933, as amended. Although not a condition to the
consummation of the Merger, the Merger Agreement contemplates that immediately
following the Merger, Sterling Bank will merge with and into Fleet Bank of
Massachusetts, N.A. ("Fleet Bank MA") (the "Bank Merger"). You have requested
our opinion (i) that the Merger of Sterling and Fleet will constitute a
reorganization within the meaning of section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code"), and (ii) as to certain other federal
income tax consequences arising in connection with the Merger.

        In preparing this opinion, we have reviewed such documents and
materials as we have considered necessary for the purpose of rendering such
opinion. The opinions expressed herein are based on the terms of the Merger as
described in the Merger Agreement (including exhibits thereto), as well as on
certain factual statements relating to the Merger and the transactions
contemplated thereby set forth in the Registration Statement and on certain
factual assumptions set forth below. Such assumptions have been confirmed to us
in representation letters from Sterling and Fleet dated as of the date of this
opinion letter.

        The discussion and conclusions set forth below are based on the Code,
the Treasury Regulations promulgated thereunder and existing administrative and
judicial interpretations

thereof, all of which are subject to change. No assurance therefore can be
given that the federal income tax consequences described below will not be
altered in the future.

        Capitalized terms used herein and not otherwise defined shall have the
meanings given them in the Registration Statement.

I.      Plan of Reorganization
        ----------------------

        A.      The Merger
                ----------

        Subject to the terms and conditions of the Merger Agreement, Sterling
shall be merged with and into Fleet pursuant to the Merger Agreement, the
separate existence of Sterling shall cease, and Fleet shall be the surviving
corporation of the Merger.

        At the Effective Time of the Merger, each then outstanding share of
Sterling Common Stock (other than shares held by Sterling as treasury stock or
by Fleet or Sterling or any subsidiary thereof (other than in both cases
shares held in a fiduciary capacity or as a result of debts previously
contracted)) shall be converted into and exchangeable for the number of shares
(the "Exchange Ratio") of Fleet Common Stock determined by dividing $39.50 by
the Average Closing Price, subject to adjustment as described below. The
"Average Closing Price" is the average closing sale price per share of Fleet
Common Stock on the New York Stock Exchange (as reported by THE WALL STREET
JOURNAL or, if not reported thereby, another authoritative source), for the 20
New York Stock Exchange trading days ending on the tenth business day after the
date on which the last of the regulatory approvals required to consummate the
transactions contemplated by the Merger Agreement is obtained. Notwithstanding
the foregoing, if the Average Closing Price is equal to or greater than $39.24,
the Exchange Ratio will be 1.0066; and if the Average Closing Price is equal to
or less than $29.01, the Exchange Ratio will be 1.3616; except that if the
Average Closing Price is equal to or less than $25.59, Sterling shall have the
right, waivable by it, to terminate the Merger Agreement, unless Fleet shall
have elected, at its option, to adopt as the Exchange Ratio the "Adjusted
Maximum Exchange Ratio", which shall be determined by dividing $34.84 by the
Average Closing Price.

        Fleet will not be required to issue or deliver any fractional shares
of Fleet Common Stock. In lieu of fractional shares, each holder of Sterling
Common Stock who would otherwise be entitled to receive a fractional share of
Fleet Common Stock shall receive from Fleet an amount of cash equal to the
per-share closing sale price of Fleet Common Stock on the New York Stock
Exchange as reported by THE WALL STREET JOURNAL for the New York

           , 1994


Page 3

Stock Exchange trading day immediately preceding the date of the Effective
Time, multiplied by the fraction of a share of Fleet Common Stock to which such
holder would otherwise be entitled.

        Holders of Sterling Common Stock do not have any appraisal rights under
Delaware law in connection with the Merger.

        Except in the event of termination of the Merger Agreement, each party
to the Merger will pay its own costs and expenses incurred in connection with
the Merger Agreement; provided, however, that Fleet shall pay the cost and
expenses of printing and mailing the Proxy Statement - Prospectus, and filing
and other fees paid to the Securities and Exchange Commission or any other
governmental entity in connection with the Merger and the other transactions
contemplated by the Merger Agreement. Each party to the Bank Merger will pay
its own costs and expenses incurred in connection with the Bank Merger.

        B.      The Bank Merger
                ---------------

        Immediately following the Merger, Sterling Bank will be merged with and
into Fleet Bank MA in the Bank Merger, the separate existence of Sterling Bank
will cease and Fleet Bank MA will be the surviving corporation. All of the
stock of Sterling Bank held by Fleet will be converted into shares of
non-voting Series VI Preferred Stock (the "Preferred Stock") issued by Fleet
Banking Group, Inc. ("Fleet Banking Group"), a wholly-owned subsidiary of Fleet
and the holder of all of the stock of Fleet Bank MA and Fleet Bank, National
Association.

II.     Assumptions
        -----------

        For purposes of this opinion, we have with your permission and without
investigation made the following assumptions:

        1.      There is no plan or intention by the stockholders of Sterling
to sell, exchange or otherwise dispose of a number of shares of Fleet Common
Stock received in the Merger that would reduce the Sterling stockholders'
ownership of Fleet Common Stock to a number of such shares having a value, as
of the Effective Time, of less than 50% of the value of all formerly
outstanding stock of Sterling as of the same date. For purposes of this
assumption, shares of Sterling Common Stock (i) exchanged for cash in lieu of
fractional shares of Fleet Common Stock and (ii) shares of Sterling Common
Stock held by Sterling stockholders


<PAGE>   4
Sterling Bancshares Corporation
            , 1994


Page 4



otherwise sold, redeemed or disposed of prior to and in anticipation of the
Merger are taken into account in making this assumption.

        2.      The payment in cash in lieu of fractional shares of Fleet Common
Stock is solely for the purpose of avoiding the expense and inconvenience to
Fleet of issuing fractional shares and does not represent separately bargained
for consideration. The total cash consideration that will be paid in the Merger
to the holders of Sterling Common Stock instead of issuing fractional shares of
Fleet Common Stock will be less than 1% of the total consideration that will be
issued in the transaction to the holders of Sterling Common Stock in exchange
for their shares of Sterling Common Stock. The fractional share interest of
each holder of Sterling Common Stock will be aggregated and no holder of
Sterling Common Stock will receive cash in an amount equal to or greater than 
the value of one full share of Fleet Common Stock.

        3.      The liabilities of Sterling assumed by Fleet and the liabilites 
to which the transferred assets of Sterling are subject have been incurred by
Sterling in the ordinary course of its business.

        4.      Fleet has no plan or intention to reacquire any of the Fleet
Common Stock issued in the Merger.

        5.      As of the date of the Merger Agreement, at all times between
the date of the Merger Agreement and the Effective Time, and as of the
Effective Time, Sterling had and will have only one class of stock outstanding.

        6.      Prior to the Merger, the only business of Sterling was that of
owning the common stock of Sterling Bank.

        7.      There is no intercorporate indebtedness existing between
Sterling and Fleet that was issued, acquired, or will be settled at a discount.

        8.      Sterling is not under the jurisdiction of a court in a Title 11
or similar case within the meaning of section 368(a)(3)(A) of the Code.

        9.      As of the Effective Time of the Merger, the fair market value
and the total adjusted basis of the assets of Sterling transferred to Fleet
will equal or exceed the sum of the liabilities assumed by Fleet plus the
amount of liabilities, if any, to which the transferred assets are subject.



<PAGE>   5
Sterling Bancshares Corporation
            , 1994


Page 5

        10.     There is no plan or intention by Fleet to dispose of any of the
Series VI Preferred Stock of Fleet Banking Group received by Fleet in the Bank
Merger.

        11.     Fleet Bank MA will aquire at least 90% of the fair market value
of Sterling Bank's net assets and at least 70% of Sterling Bank's gross assets
held by Sterling Bank prior to the Bank Merger. For purposes of this
assumption, Sterling Bank assets used to pay its reorganization expenses and
all distributions (except for regular, normal dividends) made by Sterling Bank
immediately preceeding the transfer, will be included as assets of Sterling
Bank held immediately prior to the Bank Merger.

        12.     All of the outstanding stock of Fleet Bank MA will be owned by
Fleet Banking Group immediately prior to the Bank Merger. Following the Bank
Merger, Fleet Bank MA will not issue additional shares of its stock that would
result in Fleet Banking Group losing "control" of Fleet Bank MA within the
meaning of section 368(c)(1) of the Code.

        13.     Following the Bank Merger, Fleet Bank MA will continue the
historic business of Sterling Bank or use a significant portion of Sterling
Bank's historic business assets in a business.

        14.     Neither Fleet nor Fleet Banking Group has any plan or intention
to sell, exchange or otherwise dispose of any of the common stock of Fleet Bank
MA, to liquidate Fleet Bank MA or to cause Fleet Bank MA to dispose of any of
the assets of Sterling Bank acquired by Fleet Bank MA in the Bank Merger,
except for dispositions made in the ordinary course of business.

        15.     As of the effective time of the Bank Merger, the fair market
value and the total adjusted basis of the assets of Sterling Bank transferred
to Fleet Bank MA will equal or exceed the sum of the liabilities assumed by
Fleet Bank MA and the liabilities, if any, to which the transferred assets are
subject.

        16.     Sterling Bank is not under the jurisdiction of a court in a
Title 11 or similar case within the meaning of section 368(a)(3)(A) of the
Code.

        17.     Fleet Banking Group has no plan or intention to reacquire any
of its Class VI Preferred Stock issued in the Bank Merger.

        18.     The liabilities of Sterling Bank assumed by Fleet Bank MA and
the liabilities to which the transferred assets of Sterling Bank are subject
were incurred by Sterling Bank in
<PAGE>   6
Sterling Bancshares Corporation
            , 1994


Page 6

the ordinary course of its business. There is no intercorporate indebtedness
existing between Fleet Banking Group and Sterling Bank or between Fleet Bank
MA and Sterling Bank that was issued, acquired, or will be settled at a
discount.

        19.     Sterling, Sterling Bank and the stockholders of Sterling will
pay all of their own costs and expenses incurred in connection with the Merger,
other than as noted above. Any costs or expenses properly attributable to
Sterling and paid by Fleet are and will be solely and directly related to the
Merger and will be paid by having Fleet assume the liability for such costs or
expenses. No payment of cash or other property will be made to Sterling or
Sterling Bank by any party.

        21.     None of Fleet, Sterling, Fleet Banking Group, Fleet Bank MA, or
Sterling Bank is an investment company as defined in section 368(a)(2)(F) of
the Code.

        22.     Both the "Affiliated Group" of which Fleet is the common parent
and the "Affiliated Group" of which Sterling is the common parent file
consolidated federal income tax returns. "Affiliated Group" shall have the
meaning given to it in section 1504(a) of the Code.

III.    Opinions
        --------
        Based on the foregoing, it is our opinion that:

        1.      The Merger of Sterling into Fleet will constitute a
reorganization within the meaning of section 368(a) of the Code, and for
federal income tax purposes no gain or loss will be recognized by Sterling or
Fleet as a result of the Merger.

        2.      No gain or loss will be recognized by a Sterling stockholder
(other than as result of cash payments made in lieu of fractional shares) upon
the exchange of his Sterling Common Stock for Fleet Common Stock.

        3.      The tax basis of the Fleet Common Stock received by a Sterling
stockholder who exchanges his Sterling Common Stock for Fleet Common Stock will
be the same as such stockholder's tax basis in the Sterling Common Stock
surrendered in exchange therefor (subject to any adjustments required by the
receipt of cash in lieu of a fractional share interest of Fleet Common Stock).
<PAGE>   7
Sterling Bancshares Corporation
            , 1994


Page 7


        4.      The holding period for federal income tax purposes of the Fleet
Common Stock received by a Sterling stockholder will include the period during
which the Sterling Common Stock surrendered in exchange therefor was held
(provided that such Sterling Common Stock was held by such Sterling
stockholder as a capital asset at the Effective Time).

        5.      Cash, if any, received by a Sterling stockholder in lieu of a
fractional share interest of Fleet Common Stock will be treated as having been
received in a distribution in full payment in exchange for the fractional share
interest of Fleet Common Stock which he would otherwise be entitled to receive,
and any gain or loss so recognized will qualify as capital gain or loss
(assuming the Sterling Common Stock was a capital asset in such stockholder's
hands at the Effective Time).

        You should recognize that our opinions are not binding on the Internal
Revenue Service and that the Internal Revenue Service may disagree with the
opinions contained herein. Although we believe that our opinions will be
sustained if challenged, there can be no assurance to this effect.

        This opinion is furnished solely for the benefit of the addressee in
connection with the transactions contemplated by the Merger Agreement and may
not be relied upon by any other person or entity or for any other purpose
without our prior written consent.
