       A      Certificate of Designation

                                       ii

 
          This RIGHTS AGREEMENT, dated as of January 5, 1996, is made between
THE SAFETY FUND CORPORATION, a Massachusetts corporation (the "Company"), and
Fleet National Bank of Massachusetts, a national banking association, as Rights
Agent (the "Rights Agent").

          The Board of Directors of the Company has authorized and declared a
distribution of one Right (as hereinafter defined) for each share of Common
Stock, $5.00 par value, of the Company (the "Common Stock") outstanding at the
Close of Business (as hereinafter defined) on January 5, 1996 (the "Record
Date"), and has authorized the issuance of one Right (as such number may
hereafter be adjusted pursuant to the provisions of this Rights Agreement) with
respect to each share of Common Stock that shall become outstanding between the
Record Date and the earliest of the Distribution Date, the Redemption Date or
the Expiration Date (as such terms are hereinafter defined); PROVIDED, HOWEVER,
that Rights may be issued with respect to shares of Common Stock that shall
become outstanding after the Distribution Date and prior to the earlier of the
Redemption Date or the Expiration Date in accordance with the provisions of
Section 23.  Each Right shall initially represent the right to purchase one one-
thousandth (1/1000th) of a share of Series A Participating Cumulative Preferred
Stock, par value $10.00 per share, of the Company (the "Preferred Shares"),
having the powers, rights and preferences set forth in the Certificate of
Designation attached as Exhibit A.

          Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

          Section 1.  CERTAIN DEFINITIONS.  For purposes of this Rights
Agreement, the following terms have the meanings indicated:

          "ACQUIRING PERSON" shall mean any Person who or which, alone or
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of the Capital Shares then outstanding that equals or exceeds
such Person's Ownership Threshold, but shall not include (a) the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or of any of
its Subsidiaries, or any Person holding Capital Shares for or pursuant to the
terms of any such employee benefit plan or (b) any such Person who has become
such a Beneficial Owner solely because (i) of a change in the aggregate number
of Capital Shares outstanding since the last date on which such Person acquired
Beneficial Ownership of any Capital Shares or (ii) it acquired such Beneficial
Ownership in the good faith belief that such acquisition would not cause such
Beneficial Ownership to exceed such Person's Ownership Threshold and such Person
relied in good faith in computing the percentage of its Beneficial Ownership on
publicly filed reports or documents of the Company which are inaccurate or out-
of-date.  Notwithstanding clause (b) of the prior sentence, if any Person that
is not an Acquiring Person due to such clause (b) does not reduce its percentage
of Beneficial Ownership of Capital Shares to an amount less than such Person's
Ownership Threshold by the Close of Business on the fifth Business Day after
notice from the Company (the date of notice being the first day) that such
Person's Beneficial Ownership of Capital Shares so exceeds such Person's
Ownership Threshold, such Person shall, at the end of such five Business Day
period, become an Acquiring Person (and such

                                       1

 
clause (b) shall no longer apply to such Person).  For purposes of this
definition, the determination whether any Person acted in "good faith" shall be
conclusively determined by the Board of Directors of the Company.

          "AFFILIATE" and "ASSOCIATE", when used with reference to any Person,
shall have the respective meanings ascribed to such terms in Rule 12b-2 of the
General Rules and Regulations under the Exchange Act, as in effect on the date
of this Rights Agreement.

          A Person shall be deemed the "BENEFICIAL OWNER" of, and shall be
deemed to "BENEFICIALLY OWN", and shall be deemed to have "BENEFICIAL OWNERSHIP"
of, any securities:

          (i)     which such Person or any of such Person's Affiliates or
     Associates is deemed to "beneficially own" within the meaning of Rule 13d-3
     of the General Rules and Regulations under the Exchange Act, as in effect
     on the date of this Rights Agreement;

          (ii)    which such Person or any of such Person's Affiliates or
     Associates has (A) the right to acquire (whether such right is exercisable
     immediately or only after the passage of time or the occurrence of events)
     pursuant to any agreement, arrangement or understanding (written or oral),
     or upon the exercise of conversion rights, exchange rights, rights (other
     than the Rights), warrants or options, or otherwise; PROVIDED, HOWEVER,
     that a Person shall not be deemed the Beneficial Owner of, or to
     beneficially own, or to have Beneficial Ownership of, securities tendered
     pursuant to a tender or exchange offer made by or on behalf of such Person
     or any of such Person's Affiliates or Associates until such tendered
     securities are accepted for purchase or exchange thereunder, or (B) the
     right to vote pursuant to any agreement, arrangement or understanding
     (written or oral); PROVIDED, HOWEVER, that a Person shall not be deemed the
     Beneficial Owner of, or to beneficially own, any security if (1) the
     agreement, arrangement or understanding (written or oral) to vote such
     security arises solely from a revocable proxy or consent given to such
     Person pursuant to a definitive proxy statement filed with the Securities
     and Exchange Commission and otherwise in accordance with, the applicable
     rules and regulations under the Exchange Act and (2) the beneficial
     ownership of such security is not also then reportable on Schedule 13D
     under the Exchange Act (or any comparable or successor report); or

          (iii)   which are beneficially owned, directly or indirectly, by any
     other Person with which such Person or any of such Person's Affiliates or
     Associates has any agreement, arrangement or understanding (written or
     oral), or is acting in concert or with conscious parallel behavior, for the
     purpose of acquiring, holding, voting (except pursuant to a revocable proxy
     as described in clause (ii)(B) of this definition) or disposing of any
     securities of the Company.  Attribution of a Person's Beneficial Ownership
     of securities to any other Person pursuant to this clause (iii) shall be
     deemed to occur (i) automatically if the existence of an agreement,
     arrangement or understanding (written or oral), or actions in concert or
     with conscious parallel behavior, of the type described in this clause
     (iii) has been disclosed to the Securities and Exchange Commission on a
     Schedule 13D or Schedule 13G under the Exchange

                                       2

 
     Act (or any successor schedule thereto) or (ii) if the Board of Directors
     of the Company determines in good faith that such an agreement, arrangement
     or understanding exists or that such actions in concert or with conscious
     parallel behavior have occurred.

Notwithstanding the foregoing, nothing contained in this definition shall cause
a Person ordinarily engaged in business as an underwriter of securities to be
the "Beneficial Owner" of, or to "beneficially own", any securities acquired in
a bona fide firm commitment underwriting pursuant to an underwriting agreement
with the Company.

          "BOOK VALUE", when used with reference to Capital Shares issued by any
Person, shall mean the amount of equity of such Person applicable to each
Capital Share, determined (i) in accordance with generally accepted accounting
principles in effect on the date as of which such Book Value is to be
determined, (ii) using all the consolidated assets and all the consolidated
liabilities of such Person on the date as of which such Book Value is to be
determined, except that no value shall be included in such assets for goodwill
arising from consummation of a business combination, and (iii) after giving
effect to (A) the exercise of all rights, options and warrants to purchase such
Capital Shares (other than the Rights), and the conversion of all securities
convertible into such Capital Shares, at an exercise or conversion price, per
Capital Share, which is less than such Book Value before giving effect to such
exercise or conversion (whether or not exercisability or convertibility is
conditioned upon occurrence of a future event), (B) all dividends and other
distributions on the capital stock of such Person declared prior to the date as
of which such Book Value is to be determined and to be paid or made after such
date, and (C) any other agreement, arrangement or understanding (written or
oral), or transaction or other action prior to the date as of which such Book
Value is to be determined which would have the effect of thereafter reducing
such Book Value.

          "BUSINESS COMBINATION" shall have the meaning set forth in Section
11(c)(I).

          "BUSINESS DAY" shall mean each Monday, Tuesday, Wednesday, Thursday
and Friday which is not a day on which banking institutions in Boston,
Massachusetts or the city in which the principal office of the Rights Agent is
located, are authorized or obligated by law or executive order to close.

          "CAPITAL SHARES", when used with reference to the Company prior to a
Business Combination, shall mean the shares of Common Stock or any other shares
of capital stock of the Company into which the Common Stock shall be
reclassified or changed.  "Capital Shares", when used with reference to any
Person (other than the Company prior to a Business Combination), shall mean
shares of capital stock of such Person (if such Person is a corporation) of any
class or series, or units of equity interests in such Person (if such Person is
not a corporation) of any class or series, the terms of which do not limit (as a
maximum amount and not merely in proportional terms) the amount of dividends or
income payable or distributable on such class or series or the amount of assets
distributable on such class or series upon any voluntary or involuntary
liquidation, dissolution or winding up of such Person and do not provide that
such class or series is subject to redemption at the option of such Person, or
any shares of capital stock or units of equity interests into which

                                       3

 
the foregoing shall be reclassified or changed; PROVIDED, HOWEVER, that, if at
any time there shall be more than one such class or series of capital stock or
equity interests of such Person, "Capital Shares" of such Person shall include
all such classes and series substantially in the proportion of the total number
of shares or other units of each such class or series outstanding at such time.
 
          "CERTIFICATE OF DESIGNATION" shall mean the Certificate of Vote of
Directors Establishing a Series of a Class of Stock setting forth the powers,

more other Persons by or through stock ownership, agency or otherwise; and the
terms "controlling" and "controlled" shall have meanings correlative to the
foregoing.

          "DISTRIBUTION DATE" shall have the meaning set forth in Section 3(b).

          "EXCHANGE ACT" shall mean the Securities Exchange Act of 1934, as in

the last day of the Company's monthly accounting period next preceding the date
in question, prepared in accordance with generally accepted accounting
principles then in effect.

          "MARKET VALUE", when used with reference to any class of Capital
Shares on any date, shall be deemed to be the average of the daily closing
prices, per share, of any such class for the period which is the shorter of (1)

reflect the effect of such action on the market price of such class.  The

and asked prices as furnished by a professional market maker making a market in
such securities selected by the Board of Directors of the Company.  If on any
such Trading Day no market maker is making a market in such securities for any
reason, the closing price of such securities on such Trading Day shall be deemed
to be the fair value of such securities as determined in good faith by the Board
of Directors of the Company (whose determination shall be described in a
statement filed with the Rights Agent and shall be binding on the Rights Agent,
the holders of Rights and all other Persons); PROVIDED, HOWEVER, that for the
purpose of determining the closing price of the Preferred Shares for any Trading
Day on which there is no such market maker for the Preferred Shares the closing
price on such Trading Day shall be deemed to be the Formula Number (as defined
in the Certificate of Designation) times the closing price of the Common Stock
of the Company on such Trading Day.

Company or of any of its Subsidiaries, or any Person holding Capital Shares for
or pursuant to the terms of any such employee benefit plan) for outstanding
Capital Shares, if upon consummation of such tender or exchange offer such
Person's Beneficial Ownership of Capital Shares then outstanding could equal or
exceed such Person's Ownership Threshold (the Close of Business on the earlier

Certificates.

          (c)  With respect to any certificate for Capital Shares, until the
earliest of the Distribution Date, the Redemption Date or the Expiration Date,
the Rights associated with the Capital Shares represented by any such
certificate shall be evidenced by such certificate alone, the registered holders
of the Capital Shares shall also be the registered holders of the associated

constitute the transfer of the Rights associated with the Capital Shares
represented thereby.

          (d)  Certificates issued for Capital Shares after the Record Date
(including, without limitation, upon transfer or exchange of outstanding Capital
Shares), but prior to the earliest of the Distribution Date, the Redemption Date

them the following legend:

          This certificate also evidences and entitles the holder hereof to

     1996, as it may be amended from time to time (the "Rights Agreement"),
     between THE SAFETY FUND CORPORATION (the "Company") and FLEET NATIONAL BANK
     OF MASSACHUSETTS, as Rights Agent (the "Rights Agent"), the terms of which
     are hereby incorporated herein by reference and a copy of which is on file
     at the principal executive offices of the Company.  Under certain
     circumstances, as set forth in the Rights Agreement, such Rights will be
     evidenced by separate certificates and will no longer be evidenced by this
     certificate.  The Company will mail to the holder of this certificate a
     copy of the Rights Agreement without charge after receipt of a written
     request therefor.  Rights beneficially owned by Acquiring Persons or their
     Affiliates or Associates (as such terms are defined in the Rights
     Agreement) and by any subsequent holder of such Rights are null and void
     and nontransferable.

Notwithstanding this paragraph (d), the omission of a legend shall not affect
the enforceability of any part of this Rights Agreement or the rights of any
holder of Rights.

          Section 4.  FORM OF RIGHT CERTIFICATES.  The Right Certificates (and
the form of election to purchase and form of assignment to be printed on the
reverse side thereof)

                                       8

 
shall be in substantially the form set forth as Exhibit B and may have such
marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Rights Agreement, or as may be required
to comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the Rights
may, from time to time be listed, or to conform to usage.  Subject to the
provisions of Sections 7, 11 and 23, the Right Certificates, whenever issued,
shall be dated as of the Distribution Date, and on their face shall entitle the
holders thereof to purchase such number of Preferred Shares as shall be set
forth therein for the Purchase Price set forth therein, subject to adjustment
from time to time as herein provided.

          Section 5.  EXECUTION, COUNTERSIGNATURE AND REGISTRATION.  (a)  The
Right Certificates shall be executed on behalf of the Company by the Chairman of
the Board, the Chief Executive Officer, the President, the Chief Operating
Officer, the Chief Financial Officer, the Treasurer or a Vice President (whether
preceded by any additional title) of the Company, either manually or by
facsimile signature, and have affixed thereto the Company's seal or a facsimile
thereof which shall be attested by the Secretary, an Assistant Secretary or a
Vice President (whether preceded by any additional title, provided that such
Vice President shall not have also executed the Right Certificates) of the
Company, either manually or by facsimile signature.  The Right Certificates
shall be manually countersigned by the Rights Agent and shall not be valid or
obligatory for any purpose unless so countersigned.  In case any officer of the
Company who shall have signed any of the Right Certificates shall cease to be
such an officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right Certificates may nevertheless
be countersigned by the Rights Agent and issued and delivered by the Company
with the same force and effect as though the person who signed such Right
Certificates had not ceased to be such an officer of the Company; and any Right
Certificate may be signed on behalf of the Company by any person who, at the
actual date of execution of such Right Certificate, shall be a proper officer of
the Company to sign such Right Certificate, although at the date of execution of
this Rights Agreement any such person was not such an officer of the Company.

          (b)  Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its office in Hartford, Connecticut, books for registration
and transfer of the Right Certificates issued hereunder.  Such books shall show
the names and addresses of the respective holders of the Right Certificates, the
number of Rights evidenced by each of the Right Certificates, the certificate
number of each of the Right Certificates and the date of each of the Right
Certificates.

          Section 6. TRANSFER, SPLIT-UP, COMBINATION AND EXCHANGE OF RIGHT
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES;
UNCERTIFICATED RIGHTS. (a) Subject to the provisions of Sections 7(e) and 15, at
any time after the Distribution Date, and at or prior to the Close of Business
on the earlier of the Redemption Date or the Expiration Date, any Right
Certificate or Right Certificates may be transferred, split-up, combined or
exchanged for another Right Certificate or Right Certificates representing, in
the aggregate, the same number of Rights as the Right Certificate or Right
Certificates surrendered then represented.  Any registered holder desiring to
transfer, split-up, combine or exchange any Right Certificate shall make such
request in writing delivered

                                       9

 
to the Rights Agent and shall surrender the Right Certificate or Right
Certificates to be transferred, split-up, combined or exchanged at the office of
the Rights Agent; PROVIDED, HOWEVER, that neither the Rights Agent nor the
Company shall be obligated to take any action whatsoever with respect to the
transfer of any Right Certificate surrendered for transfer until the registered
holder shall have completed and signed the certification contained in the form
of assignment on the reverse side of such Right Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request.  Thereupon the Rights Agent shall, subject to Sections
7(e) and 15, countersign and deliver to the Person entitled thereto a Right
Certificate or Right Certificates, as the case may be, as so requested.  The
Company may require payment of a sum sufficient to cover any tax or governmental
charge that may be imposed in connection with any transfer, split-up,
combination or exchange of Right Certificates.

          (b)  Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a valid Right Certificate, and, in case of loss, theft or destruction, of
indemnity or security reasonably satisfactory to them, and, at the Company's
request, reimbursement to the Company and the Rights Agent of all reasonable
expenses incidental thereto, and upon surrender to the Rights Agent and
cancellation of the Right Certificate if mutilated, the Company will make a new
Right Certificate of like tenor and deliver such new Right Certificate to the
Rights Agent for countersignature and delivery to the registered owner in lieu
of the Right Certificate so lost, stolen, destroyed or mutilated.

          (c)  Notwithstanding any other provision hereof, the Company and the
Rights Agent may amend this Rights Agreement to provide for uncertificated
Rights in addition to or in place of Rights evidenced by Right Certificates.

          Section 7. EXERCISE OF RIGHTS; EXPIRATION DATE OF RIGHTS. (a) Subject
to Section 7(e) and except as otherwise provided herein (including Section 11),
each Right shall entitle the registered holder thereof, upon exercise thereof as
provided herein, to purchase for the Purchase Price, at any time after the
Distribution Date and at or prior to the earlier of (i) the Close of Business on
the 10th anniversary of the date of this Rights Agreement (the Close of Business
on such date being the "Expiration Date") or (ii) the Redemption Date, one one-
thousandth (1/1000th) of a Preferred Share, subject to adjustment from time to
time as provided in Sections 11 and 12.

          (b)  The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein) in whole or in
part at any time after the Distribution Date, upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the office of the Rights Agent in
Hartford, Connecticut, together with payment of the Purchase Price for each one-
thousandth (1/1000th) of a Preferred Share as to which the Rights are exercised,
at or prior to the earlier of (i) the Expiration Date or (ii) the Redemption
Date.

          (c)  Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the

                                       10

 
Purchase Price for the Preferred Shares to be purchased together with an amount
equal to any applicable transfer tax, in lawful money of the United States of
America, in cash or by certified check or money order payable to the order of
the Company, the Rights Agent shall thereupon (i) either (A) promptly
requisition from any transfer agent of the Preferred Shares (or make available,
if the Rights Agent is the transfer agent) certificates for the number of
Preferred Shares to be purchased and the Company hereby irrevocably authorizes
its transfer agent to comply with all such requests or (B) if the Company shall
have elected to deposit the Preferred Shares with a depositary agent under a
depositary arrangement, promptly requisition from the depositary agent
depositary receipts representing the number of one-thousandths (1/1000ths) of a
Preferred Share to be purchased (in which case certificates for the Preferred
Shares to be represented by such receipts shall be deposited by the transfer
agent with the depositary agent) and the Company will direct the depositary
agent to comply with all such requests, (ii) when appropriate, promptly
requisition from the Company the amount of cash to be paid in lieu of issuance
of fractional shares in accordance with Section 15, (iii) promptly after receipt
of such certificates or depositary receipts, cause the same to be delivered to
or upon the order of the registered holder of such Right Certificate, registered
in such name or names as may be designated by such holder and (iv) when
appropriate, after receipt promptly deliver such cash to or upon the order of
the registered holder of such Right Certificate.

          (d)  In case the registered holder of any Right Certificate shall
exercise fewer than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent and delivered to the registered holder of such Right
Certificate or to his duly authorized assigns, subject to the provisions of
Section 15.

          (e)  Notwithstanding anything in this Rights Agreement to the
contrary, any Rights that are at any time beneficially owned by an Acquiring
Person or any Affiliate or Associate of an Acquiring Person shall be null and
void and nontransferable, and any holder of any such Right (including any
purported transferee or subsequent holder) shall not have any right to exercise
or transfer any such Right.

          (f)  Notwithstanding anything in this Rights Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder of any Right
Certificates upon the occurrence of any purported exercise as set forth in this
Section 7 unless such registered holder shall have (i) completed and signed the
certificate contained in the form of election to purchase set forth on the
reverse side of the Right Certificate surrendered for such exercise and (ii)
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request.

          (g)  The Company may temporarily suspend, for a period of time not to
exceed 90 calendar days after the Distribution Date, the exercisability of the
Rights in order to prepare and file a registration statement under the
Securities Act, on an appropriate form, with respect to the Preferred Shares
purchasable upon exercise of the Rights and permit such registration statement
to become effective; PROVIDED, HOWEVER, that no such suspension shall remain
effective after, and the Rights shall without any further action by the Company
or any

                                       11

 
other Person become exercisable immediately upon, the effectiveness of such
registration statement.  Upon any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended and shall issue a further public announcement at such time
as the suspension is no longer in effect.  Notwithstanding any provision herein
to the contrary, the Rights shall not be exercisable in any jurisdiction if the
requisite qualification under the blue sky or securities laws of such
jurisdiction shall not have been obtained or the exercise of the Rights shall
not be permitted under applicable law.

          Section 8. CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES.  All
Right Certificates surrendered or presented for the purpose of exercise,
transfer, split-up, combination or exchange shall, and any Right Certificate
representing Rights that have become null and void and nontransferable pursuant
to Section 7(e) surrendered or presented for any purpose shall, if surrendered
or presented to the Company or to any of its agents, be delivered to the Rights
Agent for cancellation or in canceled form, or, if surrendered or presented to
the Rights Agent, shall be canceled by it, and no Right Certificates shall be
issued in lieu thereof except as expressly permitted by this Rights Agreement.
The Company shall deliver to the Rights Agent for cancellation and retirement,
and the Rights Agent shall so cancel and retire, any Right Certificate purchased
or acquired by the Company.  The Rights Agent shall deliver all canceled Right
Certificates to the Company, or shall, at the written request of the Company,
destroy such canceled Right Certificates, and in such case shall deliver a
certificate of destruction thereof to the Company.

          Section 9. RESERVATION AND AVAILABILITY OF PREFERRED SHARES. (a) The
Company covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued Preferred Shares or any authorized
and issued Preferred Shares held in its treasury, free from preemptive rights or
any right of first refusal, a number of Preferred Shares sufficient to permit
the exercise in full of all outstanding Rights.

          (b)  In the event that there shall not be sufficient Preferred Shares
issued but not outstanding or authorized but unissued to permit the exercise or
exchange of Rights in accordance with Section 11, the Company covenants and
agrees that it will take all such action as may be necessary to authorize
additional Preferred Shares for issuance upon the exercise or exchange of Rights
pursuant to Section 11; PROVIDED, HOWEVER, that if the Company is unable to
cause the authorization of additional Preferred Shares, then the Company shall,
or in lieu of seeking any such authorization, the Company may, to the extent
necessary and permitted by applicable law and any agreements or instruments in
effect prior to the Distribution Date to which it is a party, (A) upon surrender
of a Right, pay cash equal to the Purchase Price in lieu of issuing Preferred
Shares and requiring payment therefor, (B) upon due exercise of a Right and
payment of the Purchase Price for each Preferred Share as to which such Right is
exercised, issue equity securities having a value equal to the value of the
Preferred Shares which otherwise would have been issuable pursuant to Section
11, which value shall be determined by a nationally recognized investment
banking firm selected by the Board of Directors of the Company or (C) upon due
exercise of a Right and payment of the Purchase Price for each Preferred Share
as to which such Right is exercised, distribute a combination of Preferred
Shares, cash and/or other equity and/or debt securities having an aggregate
value equal to the value of the Preferred Shares which otherwise would have been

                                       12

 
issuable pursuant to Section 11, which value shall be determined by a nationally
recognized investment banking firm selected by the Board of Directors of the
Company.  To the extent that any legal or contractual restrictions (pursuant to
agreements or instruments in effect prior to the Distribution Date to which it
is party) prevent the Company from paying the full amount payable in accordance
with the foregoing sentence, the Company shall pay to holders of the Rights as
to which such payments are being made all amounts which are not then restricted
on a pro rata basis as such payments become permissible under such legal or
contractual restrictions until such payments have been paid in full.

          (c)  The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all Preferred Shares delivered upon
exercise or exchange of Rights shall, at the time of delivery of the
certificates for such Preferred Shares (subject to payment of the Purchase
Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

          (d)  So long as the Preferred Shares issuable upon the exercise or
exchange of Rights are to be listed on any national securities exchange, the
Company covenants and agrees to use its best efforts to cause, from and after
such time as the Rights become exercisable or exchangeable, all Preferred Shares
reserved for such issuance to be listed on such securities exchange upon
official notice of issuance upon such exercise or exchange.

          (e)  The Company further covenants and agrees that it will pay when
due and payable any and all Federal and state transfer taxes and charges which
may be payable in respect of the issuance or delivery of Right Certificates or
of any Preferred Shares or Capital Shares or other securities upon the exercise
or exchange of the Rights. The Company shall not, however, be required to pay
any transfer tax which may be payable in respect of any transfer or delivery of
Right Certificates to a Person other than, or in respect of the issuance or
delivery of certificates for the Preferred Shares or Capital Shares or other
securities, as the case may be, in a name other than that of, the registered
holder of the Right Certificate evidencing Rights surrendered for exercise or
exchange or to issue or deliver any certificates for Preferred Shares or Capital
Shares or other securities, as the case may be, upon the exercise or exchange of
any Rights until any such tax shall have been paid (any such tax being payable
by the holder of such Right Certificate at the time of surrender) or until it
has been established to the Company's satisfaction that no such tax is due.

          Section 10.  PREFERRED SHARES RECORD DATE.  Each Person in whose name
any certificate for Preferred Shares or Capital Shares or other securities is
issued upon the exercise or exchange of Rights shall for all purposes be deemed
to have become the holder of record of the Preferred Shares or Capital Shares or
other securities, as the case may be, represented thereby on, and such
certificate shall be dated, the date upon which the Right Certificate evidencing
such Rights was duly surrendered and payment of any Purchase Price (and any
applicable transfer taxes) was made; PROVIDED, HOWEVER, that, if the date of
such surrender and payment is a date upon which the transfer books of the
Company for the Preferred Shares or Capital Shares or other securities, as the
case may be, are closed, such Person shall be deemed to have become the record
holder of such Preferred Shares or Capital Shares or other securities, as the
case may be, on, and such certificate shall be dated, the

                                       13

 
next succeeding Business Day on which the transfer books of the Company for the
Preferred Shares or Capital Shares or other securities, as the case may be, are
open.

     Section 11.  ADJUSTMENTS IN RIGHTS AFTER THERE IS AN ACQUIRING PERSON;
EXCHANGE OF RIGHTS FOR SHARES; BUSINESS COMBINATIONS.  (a) Upon a Person
becoming an Acquiring Person, proper provision shall be made so that each holder
of a Right, except as provided in Section 7(e), shall thereafter have a right to
receive, upon exercise thereof for the Purchase Price in accordance with the
terms of this Rights Agreement, such number of one-thousandths (1/1000ths) of a
Preferred Share as shall equal the result obtained by multiplying the Purchase
Price by a fraction, the numerator of which is the number of one-thousandths
(1/1000ths) of a Preferred Share for which a Right is then exercisable and the
denominator of which is 50% of the Market Value of the Common Stock on the date
on which a Person becomes an Acquiring Person.  As soon as practicable after a
Person becomes an Acquiring Person (provided the Company shall not have elected
to make the exchange permitted by Section 11(b)(I) for all outstanding Rights),
the Company covenants and agrees to use its best efforts to:

          (I)     prepare and file a registration statement under the Securities
     Act, on an appropriate form, with respect to the Preferred Shares
     purchasable upon exercise of the Rights;

          (II)    cause such registration statement to become effective as soon
     as practicable after such filing;

          (III)   cause such registration statement to remain effective (with a
     prospectus at all times meeting the requirements of the Securities Act)
     until the Expiration Date; and

          (IV)    qualify or register the Preferred Shares purchasable upon
     exercise of the Rights under the blue sky or securities laws of such
     jurisdictions as may be necessary or appropriate.

          (b)(I) The Board of Directors of the Company may, at its option, at
any time after a Person becomes an Acquiring Person, mandatorily exchange all or
part of the then outstanding and exercisable Rights (which shall not include
Rights that shall have become null and void and nontransferable pursuant to the
provisions of Section 7(e)) for consideration per Right consisting of one-half
of the securities that would be issuable at such time upon the exercise of one
Right in accordance with Section 11(a) or, if applicable, Section 9(b) (the
consideration issuable per Right pursuant to this Section 11(b)(I) being the
"Exchange Consideration").  The Board of Directors of the Company may, at its
option, issue, in substitution for Preferred Shares, shares of Common Stock in
an amount per Preferred Share equal to the Formula Number if there are
sufficient shares of Common Stock issued but not outstanding or authorized but
unissued.  If the Board of Directors of the Company elects to exchange all the
Rights for Exchange Consideration pursuant to this Section 11(b)(I) prior to the
physical distribution of the Rights Certificates, the Corporation may distribute
the Exchange Consideration in lieu of distributing Right Certificates, in which
case for purposes

                                       14

 
of this Rights Agreement holders of Rights shall be deemed to have
simultaneously received and surrendered for exchange Right Certificates on the
date of such distribution.

          (II)    Any action of the Board of Directors of the Company ordering
the exchange of any Rights pursuant to Section 11(b)(I) shall be irrevocable
and, immediately upon the taking of such action and without any further action
and without any notice, the right to exercise any such Right pursuant to Section
11(a) shall terminate and the only right thereafter of a holder of such Right
shall be to receive the Exchange Consideration in exchange for each such Right
held by such holder or, if the Exchange Consideration shall not have been paid
or issued, to exercise any such Right pursuant to Section 11(c)(I). The Company
shall promptly give public notice of any such exchange; PROVIDED, HOWEVER, that
the failure to give, or any defect in, such notice shall not affect the validity
of such exchange. The Company promptly shall mail a notice of any such exchange
to all holders of such Rights at their last addresses as they appear upon the
registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of exchange will state the method by which the exchange
of the Rights for the Exchange Consideration will be effected and, in the event
of any partial exchange, the number of Rights which will be exchanged. Any
partial exchange shall be effected pro rata based on the number of Rights (other
than Rights which shall have become null and void and nontransferable pursuant
to the provisions of Section 7(e)) held by each holder of Rights.

          (c)(I) In the event that, following a Distribution Date, directly or
indirectly, any transactions specified in the following clause (i), (ii) or
(iii) of this Section 11(c) (each such transaction being a "Business
Combination") shall be consummated:

          (i)    the Company shall consolidate with, or merge with and into, any
     Acquiring Person or any Affiliate or Associate of an Acquiring Person;

          (ii)   any Acquiring Person or any Affiliate or Associate of an
     Acquiring Person shall merge with and into the Company and, in connection
     with such merger, all or part of the Capital Shares shall be changed into
     or exchanged for capital stock or other securities of the Company or of any
     Acquiring Person or Affiliate or Associate of an Acquiring Person or cash
     or any other property; or

          (iii)  the Company shall sell, lease, exchange or otherwise transfer
     or dispose of (or one or more of its Subsidiaries shall sell, lease,
     exchange or otherwise transfer or dispose of), in one or more transactions,
     the Major Part of the assets of the Company and its Subsidiaries (taken as
     a whole) to any Acquiring Person or any Affiliate or Associate of an
     Acquiring Person,

then, in each such case, proper provision shall be made so that each holder of a
Right, except as provided in Section 7(e), shall thereafter have the right to
receive, upon the exercise thereof for the Purchase Price in accordance with the
terms of this Rights Agreement, the securities specified below (or, at such
holder's option, the securities specified in Section 11(a)):

                                       15

 
          (A)     If the Principal Party in such Business Combination has
     Registered Capital Shares outstanding, each Right shall thereafter
     represent the right to receive, upon the exercise thereof for the Purchase
     Price in accordance with the terms of this Rights Agreement, such number of
     Registered Capital Shares of such Principal Party, free and clear of all
     liens, encumbrances or other adverse claims, as shall have an aggregate
     Market Value equal to the result obtained by multiplying the Purchase Price
     by two;

          (B)     If the Principal Party involved in such Business Combination
     does not have Registered Capital Shares outstanding, each Right shall
     thereafter represent the right to receive, upon the exercise thereof for
     the Purchase Price in accordance with the terms of this Rights Agreement,
     at the election of the holder of such Right at the time of the exercise
     thereof, any of:

                  (1)  such number of Capital Shares of the Surviving Person in
          such Business Combination as shall have an aggregate Book Value
          immediately after giving effect to such Business Combination equal to
          the result obtained by multiplying the Purchase Price by two;

                  (2)  such number of Capital Shares of the Principal Party in
          such Business Combination (if the Principal Party is not also the
          Surviving Person in such Business Combination) as shall have an
          aggregate Book Value immediately after giving effect to such Business
          Combination equal to the result obtained by multiplying the Purchase
          Price by two; or

                  (3)  if the Principal Party in such Business Combination is an
          Affiliate of one or more Persons which has Registered Capital Shares
          outstanding, such number of Registered Capital Shares of whichever of
          such Affiliates of the Principal Party has Registered Capital Shares
          with the greatest aggregate Market Value on the date of consummation
          of such Business Combination as shall have an aggregate Market Value
          on the date of such Business Combination equal to the result obtained
          by multiplying the Purchase Price by two.

          (II)    The Company shall not consummate any Business Combination
unless each issuer of Capital Shares for which Rights may be exercised, as set
forth in this Section 11(c), shall have sufficient authorized Capital Shares
that have not been issued or reserved for issuance (and which shall, when issued
upon exercise thereof in accordance with this Rights Agreement, be validly
issued, fully paid and nonassessable and free of preemptive rights, rights of
first refusal or any other restrictions or limitations on the transfer or
ownership thereof) to permit the exercise in full of the Rights in accordance
with this Section 11(c) and unless prior thereto:

          (i)     a registration statement under the Securities Act on an
     appropriate form, with respect to the Rights and the Capital Shares of such
     issuer purchasable upon exercise of the Rights, shall be effective under
     the Securities Act; and

                                       16

 
          (ii)    the Company and each such issuer shall have:

                  (A)   executed and delivered to the Rights Agent a
          supplemental agreement providing for the assumption by such issuer of
          the obligations set forth in this Section 11(c) (including the
          obligation of such issuer to issue Capital Shares upon the exercise of
          Rights in accordance with the terms set forth in Sections 11(c)(I) and
          11(c)(III)) and further providing that such issuer, at its own
          expense, will use its best efforts to:

                        (1)   cause a registration statement under the
                  Securities Act on an appropriate form, with respect to the
                  Rights and the Capital Shares of such issuer purchasable upon
                  exercise of the Rights, to remain effective (with a prospectus
                  at all times meeting the requirements of the Securities Act)
                  until the Expiration Date;

                        (2)   qualify or register the Rights and the Capital
                  Shares of such issuer purchasable upon exercise of the Rights
                  under the blue sky or securities laws of such jurisdictions as
                  may be necessary or appropriate; and

                        (3)   list the Rights and the Capital Shares of such
                  issuer purchasable upon exercise of the Rights on each
                  national securities exchange on which the Capital Shares were
                  listed prior to the consummation of the Business Combination
                  or, if the Capital Shares were not listed on a national
                  securities exchange prior to the consummation of the Business
                  Combination, on a national securities exchange;

                  (B)   furnished to the Rights Agent a written opinion of
          independent counsel stating that such supplemental agreement is a
          valid, binding and enforceable agreement of such issuer; and

                  (C)   filed with the Rights Agent a certificate of a
          nationally recognized firm of independent accountants setting forth
          the number of Capital Shares of such issuer which may be purchased
          upon the exercise of each Right after the consummation of such
          Business Combination.

          (III)   After consummation of any Business Combination and subject to
the provisions of Section 11(c)(II), (i) each issuer of Capital Shares for which
Rights may be exercised as set forth in this Section 11(c) shall be liable for,
and shall assume, by virtue of such Business Combination, all the obligations
and duties of the Company pursuant to this Rights Agreement, (ii) the term
"Company" shall thereafter be deemed to refer to such issuer, (iii) each such
issuer shall take such steps in connection with such consummation as may be
necessary to assure that the provisions hereof (including the provisions of
Sections 11(a) and 11(c)) shall thereafter be applicable, as nearly as
reasonably may be, in relation to its Capital Shares thereafter deliverable upon
the exercise of the Rights, and (iv) the number of Capital Shares of each such
issuer thereafter receivable upon exercise of any Right shall

                                       17

 
be subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions of Sections 11 and 12, and the
provisions of Section 7, 9 and 10 with respect to the Preferred Shares shall
apply, as nearly as reasonably may be, on like terms to any such Capital Shares.

          Section 12.  CERTAIN ADJUSTMENTS.  (a) To preserve the actual or
potential economic value of the Rights, if at any time after the date of this
Rights Agreement there shall be any change in the Capital Shares or the
Preferred Shares, whether by reason of stock dividends, stock splits,
recapitalizations, mergers, consolidations, combinations or exchanges of
securities, split-ups, split-offs, spin-offs, liquidations, other similar
changes in capitalization, any distribution or issuance of cash, assets,
evidences of indebtedness or subscription rights, options or warrants to holders
of Capital Shares or Preferred Shares, as the case may be (other than
distribution of the Rights or regular quarterly cash dividends) or otherwise,
then, in each such event the Board of Directors of the Company shall make such
appropriate adjustments in the number of Preferred Shares (or the number and
kind of other securities) issuable upon exercise of each Right, the Purchase
Price and Redemption Price in effect at such time and the number of Rights
outstanding at such time (including the number of Rights or fractional Rights
associated with each Capital Share) such that following such adjustment such
event shall not have had the effect of reducing or limiting the benefits the
holders of the Rights would have had absent such event.

          (b)  If, as a result of an adjustment made pursuant to Section 12(a),
the holder of any Right thereafter exercised shall become entitled to receive
any securities other than Preferred Shares, thereafter the number of such
securities so receivable upon exercise of any Right shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions of Sections 11 and 12, and the provisions of
Sections 7, 9 and 10 with respect to the Preferred Shares shall apply, as nearly
as reasonably may be, on like term, to any such other securities.

          (c)  All Rights originally issued by the Company subsequent to any
adjustment made to the amount of Preferred Shares or other securities relating
to a Right shall evidence the right to purchase, for the Purchase Price, the
adjusted number and kind of securities purchasable from time to time hereunder
upon exercise of the Rights, all subject to further adjustment as provided
herein.

          (d)  Irrespective of any adjustment or change in the Purchase Price or
the number of Preferred Shares or number or kind of other securities issuable
upon the exercise of the Rights, the Right Certificates theretofore and
thereafter issued may continue to express the terms which were expressed in the
initial Right Certificates issued hereunder.

          (e)  In any case in which action taken pursuant to Section 12(a)
requires that an adjustment be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date
the Preferred Shares and/or other securities, if any, issuable upon such
exercise over and above the Preferred Shares and/or other securities, if any,
issuable before giving effect to such adjustment; PROVIDED, HOWEVER, that the
Company shall deliver to such holder a due bill or other appropriate instrument
evidencing such holder's

                                       18

 
right to receive such additional securities upon the occurrence of the event
requiring such adjustment.

          Section 13.  CERTIFICATE OF ADJUSTMENT.  Whenever an adjustment is
made as provided in Section 11 or 12, the Company shall (a) promptly prepare a
certificate setting forth such adjustment and a brief statement of the facts
accounting for such adjustment, (b) promptly file with the Rights Agent and with
each transfer agent for the Preferred Shares a copy of such certificate and (c)
mail a brief summary thereof to each holder of a Right Certificate (or, prior to
the Distribution Date, of the Capital Shares) in accordance with Section 25.
The Rights Agent shall be fully protected in relying on any such certificate and
on any adjustment therein contained.

          Section 14.  ADDITIONAL COVENANTS.  (a) Notwithstanding any other
provision of this Rights Agreement, no adjustment to the number of Preferred
Shares (or fractions of a share) or other securities for which a Right is
exercisable or the number of Rights outstanding or associated with each Capital
Share or any similar or other adjustment shall be made or be effective if such
adjustment would have the effect of reducing or limiting the benefits the
holders of the Rights would have had absent such adjustment, including, without
limitation, the benefits under Sections 11 and 12, unless the terms of this
Rights Agreement are amended so as to preserve such benefits.

          (b)  The Company covenants and agrees that, after the Distribution
Date, except as permitted by Section 26, it will not take (or permit any
Subsidiary of the Company to take) any action if at the time such action is
taken it is intended or reasonably foreseeable that such action will reduce or
otherwise limit the benefits the holders of the Rights would have had absent
such action, including, without limitation, the benefits under Sections 11 and
12.  Any action taken by the Company during any period after any Person becomes
an Acquiring Person but prior to the Distribution Date shall be null and void
unless such action could be taken under this Section 14(b) from and after the
Distribution Date.  The Company shall not consummate any Business Combination if
any issuer of Capital Shares for which Rights may be exercised after such
Business Combination in accordance with Section 11(c) shall have taken any
action that reduces or otherwise limits the benefits the holders of the Rights
would have had absent such action, including, without limitation, the benefits
under Sections 11 and 12.

          Section 15.  FRACTIONAL RIGHTS AND FRACTIONAL SHARES.  (a) The Company
may, but shall not be required to, issue fractions of Rights or distribute Right
Certificates which evidence fractional Rights.  In lieu of such fractional
Rights, the Company may pay to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable an
amount in cash equal to the same fraction of the current market value of a whole
Right.  For purposes of this Section 15(a), the current market value of a whole
Right shall be the closing price of the Rights (as determined in a manner
similar to that of Common Stock pursuant to the second and third sentences of
the definition of Market Value contained in Section 1) for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable.

                                       19

 
          (b)  The Company may, but shall not be required to, issue fractions of
Preferred Shares upon exercise of the Rights or distribute certificates which
evidence fractional Preferred Shares.  In lieu of fractional Preferred Shares,
the Company may elect to (i) utilize a depository arrangement as provided by the
terms of the Preferred Shares or (ii) in the case of a fraction of a Preferred
Share (other than one one-thousandth (1/1000th) of a Preferred Share or any
integral multiple thereof), pay to the registered holders of Right Certificates
at the time such Rights are exercised as herein provided an amount in cash equal
to the same fraction of the current market value of one Preferred Share, if any
are outstanding and publicly traded (or the Formula Number times the current
market value of one share of Common Stock if the Preferred Shares are not
outstanding and publicly traded).  If, as a result of an adjustment made
pursuant to Section 12(a), the holder of any Right thereafter exercised shall
become entitled to receive any securities other than Preferred Shares, the
provisions of this Section 15(b) shall apply, as nearly as reasonably may be, on
like terms to such other securities.

          (c)  The Company may, but shall not be required to, issue fractions of
shares of Common Stock upon exchange of Rights pursuant to Section 11(b), or to
distribute certificates which evidence fractional shares of Common Stock.  In
lieu of such fractional shares of Common Stock, the Company may pay to the
registered holders of the Right Certificates with regard to which such
fractional shares of Common Stock would otherwise be issuable an amount in cash
equal to the same fraction of the current Market Value of one share of Common
Stock as of the date on which a Person became an Acquiring Person.

          (d)  The holder of Rights by the acceptance of the Rights expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right except as provided in this Section 15.

          Section 16.  RIGHTS OF ACTION.  (a) All rights of action in respect of
this Rights Agreement are vested in the respective registered holders of the
Right Certificates (and, prior to the Distribution Date, the registered holders
of the Capital Shares); and any registered holder of any Right Certificate (or,
prior to the Distribution Date, of the Capital Shares), without the consent of
the Rights Agent or of the holder of any other Right Certificate (or, prior to
the Distribution Date, of the Capital Shares) may, in his own behalf and for his
own benefit, enforce, and may institute and maintain any suit, action or
proceeding against the Company to enforce, or otherwise act in respect of, his
right to exercise the Rights evidenced by such Right Certificate in the manner
provided in such Right Certificate and in this Rights Agreement.  Without
limiting the foregoing or any remedies available to the holders of Rights, it is
specifically acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this Rights Agreement and shall be entitled to
specific performance of the obligations of any Person under, and injunctive
relief against actual or threatened violations of the obligations of any Person
subject to, this Rights Agreement.

          (b)  Any holder of Rights who prevails in an action to enforce the
provisions of this Rights Agreement shall be entitled to recover the reasonable
costs and expenses, including attorneys' fees, incurred in such action.

                                       20

 
          Section 17.  TRANSFER AND OWNERSHIP OF RIGHTS AND RIGHT CERTIFICATES.
(a)  Prior to the Distribution Date, the Rights will be transferable only in
connection with the transfer of the Capital Shares.

          (b)  After the Distribution Date, the Right Certificates will be
transferable, subject to Section 7(e), only on the registry books of the Rights
Agent if surrendered at the office of the Rights Agent, duly endorsed or
accompanied by a proper instrument of transfer.

          (c)  The Company and the Rights Agent may deem and treat the Person in
whose name a Right Certificate (or, prior to the Distribution Date, the
associated Capital Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificates or the associated certificate for
Capital Shares made by anyone other than the Company or the Rights Agent) for
all purposes whatsoever, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary.

          Section 18.  RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.  No
holder, as such, of any Right Certificate shall be entitled to vote or receive
dividends or be deemed, for any purpose, the holder of the Preferred Shares or
of any other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company,
including, without limitation, any right to vote for the election of directors
or upon any matter submitted to stockholders at any meeting thereof, or to give
or withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders, or to receive dividends or other
distributions or subscription rights, or otherwise, until the Right or Rights
evidenced by such Right Certificate shall have been exercised in accordance with
the provisions hereof.

          Section 19.  CONCERNING THE RIGHTS AGENT.  (a)  The Company agrees to
pay to the Rights Agent reasonable compensation for all services rendered by it
hereunder and from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Rights Agreement and the exercise and performance of its
duties hereunder.

          (b)  The Rights Agent shall be protected and shall incur no liability
for or in respect of any action taken, suffered or omitted by it in connection
with its administration of this Rights Agreement in reliance upon any Right
Certificate or certificate for the Capital Shares or for other securities of the
Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement, or other
paper or document believed by it to be genuine and to be signed, executed and,
where necessary, verified or acknowledged, by the proper Person or Persons.

          Section 20.  MERGER OR CONSOLIDATION OR CHANGE OF RIGHTS AGENT.  (a)
Any corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Rights Agent or any successor Rights
Agent shall be a party, or

                                       21

 
any corporation succeeding to the stock transfer or corporate trust business of
the Rights Agent or any successor Rights Agent, shall be the successor to the
Rights Agent under this Rights Agreement without the execution or filing of any
paper or any further act on the part of any of the parties hereto; PROVIDED that
such corporation would be eligible for appointment as a successor Rights Agent
under the provisions of Section 22.  In case, at the time such successor Rights
Agent shall succeed to the agency created by this Rights Agreement, any of the
Right Certificates shall have been countersigned but not delivered, any such
successor Rights Agent may adopt the countersignature of the predecessor Rights
Agent and deliver such Right Certificates so countersigned; and, in case at that
time any of the Right Certificates shall not have been countersigned, any
successor Rights Agent may countersign such Right Certificates either in the
name of the predecessor Rights Agent or in the name of the successor Rights
Agent; and in all such cases such Right Certificates shall have the full force
provided in the Right Certificates and in this Rights Agreement.

          (b)  In case at any time the name of the Rights Agent shall be changed
and at such time any of the Right Certificates shall have been countersigned but
not delivered, the Rights Agent may adopt the countersignature under its prior
name and deliver Right Certificates so countersigned; and, in case at that time
any of the Right Certificates shall not have been countersigned, the Rights
Agent may countersign such Right Certificates either in its prior name or in its
changed name; and in all such cases such Right Certificates shall have the full
force provided in the Right Certificates and in this Rights Agreement.

     Section 21.  DUTIES OF RIGHTS AGENT.  The Rights Agent undertakes the
duties and obligations imposed by this Rights Agreement upon the following terms
and conditions, by all of which the Company and the holders of Right
Certificates (or, prior to the Distribution Date, of the Capital Shares), by
their acceptance thereof, shall be bound:

          (a)  The Rights Agent may consult with legal counsel (who may be legal
counsel for the Company), and the advice or opinion of such counsel shall be
full and complete authorization and protection to the Rights Agent as to any
action taken, suffered or omitted by it in good faith and in accordance with
such advice or opinion.

          (b)  Whenever in the performance of its duties under this Rights
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person) be
proved or established by the Company prior to taking, refraining from taking or
suffering any action hereunder, such fact or matter (unless other evidence in
respect thereof be herein specifically prescribed) may be deemed to be
conclusively proved and established by a certificate signed by any one of the
Chairman of the Board, the Chief Executive Officer, the President, the Chief
Operating Officer, the Chief Financial Officer, the Treasurer, a Vice President
(whether preceded by any additional title) or the Secretary of the Company and
delivered to the Rights Agent; and such certificate shall be full authorization
to the Rights Agent for any action taken or suffered in good faith by it under
the provisions of this Rights Agreement in reliance upon such certificate.

          (c)  The Rights Agent shall be liable hereunder only for its own gross
negligence, bad faith or wilful misconduct.

                                       22

 
          (d)  The Rights Agent shall not be liable for or by reason of any of
the statements of fact or recitals contained in this Rights Agreement or in the
Right Certificates (except as to its countersignature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

          (e)  The Rights Agent shall not be under any responsibility in respect
of the validity of this Rights Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Rights Agreement or in any Right
Certificate; nor shall it be responsible for any adjustment required under the
provisions of Section 11 or 12 or responsible for the manner, method or amount
of any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment (except with respect to the exercise of Rights
evidenced by Right Certificates after actual notice of any such adjustment); nor
shall it by any act hereunder be deemed to make any representation or warranty
as to the authorization or reservation of any Preferred Shares or Capital Shares
to be issued pursuant to this Rights Agreement or any Right Certificate or as to
whether any Preferred Shares or Capital Shares will, when so issued, be validly
authorized and issued, fully paid and nonassessable.

          (f)  The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying out or performing by the Rights Agent of
the provisions of this Rights Agreement.

          (g)  The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
the Chief Operating Officer, the Chief Financial Officer, the Treasurer, a Vice
President (whether preceded by any additional title) or the Secretary of the
Company, in connection with its duties and it shall not be liable for any action
taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer.

          (h)  The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not the Rights
Agent under this Rights Agreement.  Nothing herein shall preclude the Rights
Agent from acting in any other capacity for the Company or for any other legal
entity.

          (i)  The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company

                                       23

 
resulting from any such act, default, neglect or misconduct provided reasonable
care was exercised in the selection and continued employment thereof.

          (j)  The Company agrees to indemnify and to hold the Rights Agent
harmless against any loss, liability, damage or expense (including reasonable
fees and expenses of legal counsel) which the Rights Agent may incur resulting
from its actions as Rights Agent pursuant to this Rights Agreement; PROVIDED,
HOWEVER, that the Rights Agent shall not be indemnified or held harmless with
respect to any such loss, liability, damage or expense incurred by the Rights
Agent as a result of, or arising out of, its own gross negligence, bad faith or
wilful misconduct.  In no case shall the Company be liable with respect to any
action, proceeding, suit or claim against the Rights Agent unless the Rights
Agent shall have notified the Company, by letter or by facsimile confirmed by
letter, of the assertion of any action, proceeding, suit or claim against the
Rights Agent, promptly after the Rights Agent shall have notice of any such
assertion of an action, proceeding, suit or claim or have been served with the
summons or other first legal process giving information as to the nature and
basis of the action, proceeding, suit or claim.  The Company shall be entitled
to participate at its own expense in the defense of any such action, proceeding,
suit or claim, and, if the Company so elects, the Company shall assume the
defense of any such action, proceeding, suit or claim.  In the event that the
Company assumes such defense, the Company shall not thereafter be liable for the
fees and expenses of any additional counsel retained by the Rights Agent, so
long as the Company shall retain counsel satisfactory to the Rights Agent, in
the exercise of its reasonable judgment, to defend such action, proceeding, suit
or claim.  The Rights Agent agrees not to settle any litigation in connection
with any action, proceeding, suit or claim with respect to which it may seek
indemnification from the Company without the prior written consent of the
Company.

          Section 22.  CHANGE OF RIGHTS AGENT.  The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Rights Agreement upon 30 days' notice in writing mailed to the Company and to
each transfer agent of the Capital Shares and the Preferred Shares by registered
or certified mail, and to the holders of the Right Certificates (or, prior to
the Distribution Date, of the Capital Shares) by first-class mail, postage
prepaid.  The Company may remove the Rights Agent or any successor Rights Agent
upon 30 days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Capital Shares and
the Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates (or, prior to the Distribution Date, of the Capital Shares)
by first-class mail.  If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent.  If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (or, prior to
the Distribution Date, of the Capital Shares) (who shall, with such notice,
submit his Right Certificate or, prior to the Distribution Date, the certificate
representing his Capital Shares, for inspection by the Company), then the
registered holder of any Right Certificate (or, prior to the Distribution Date,
of the Capital Shares) may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent.  Any successor Rights Agent, whether
appointed by the Company or by such a court, shall be a corporation organized
and doing business under the laws of the United States or of

                                       24

 
any state of the United States, in good standing, which is authorized under such
laws to exercise stock transfer or corporate trust powers and is subject to
supervision or examination by Federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50,000,000; PROVIDED that the principal transfer agent for the Capital
Shares shall in any event be qualified to be the Rights Agent.  After
appointment, the successor Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent without further act or deed; but the predecessor Rights Agent shall
deliver and transfer to the successor Rights Agent any property at the time held
by it hereunder, and execute and deliver any further assurance, conveyance, act
or deed necessary for the purpose.  Not later than the effective date of any
such appointment, the Company shall file notice thereof in writing with the
predecessor Rights Agent and each transfer agent of the Capital Shares and the
Preferred Shares, and mail a notice thereof in writing to the registered holders
of the Right Certificates (or, prior to the Distribution Date, of the Capital
Shares).  Failure to give any notice provided for in this Section 22, however,
or any defect therein shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the appointment of the successor
Rights Agent, as the case may be.

          Section 23.  ISSUANCE OF ADDITIONAL RIGHTS AND RIGHT CERTIFICATES.
Notwithstanding any of the provisions of this Rights Agreement or of the Rights
to the contrary, the Company may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved by its Board of Directors to
reflect any adjustment or change made in accordance with the provisions of this
Rights Agreement.  In addition, in connection with the issuance or sale of
Capital Shares following the Distribution Date and prior to the earlier of the
Redemption Date and the Expiration Date, the Company (a) shall, with respect to
Capital Shares so issued or sold pursuant to the exercise of stock options or
under any employee plan or arrangement, or upon the exercise, conversion or
exchange of securities, notes or debentures issued by the Company, and (b) may,
in any other case, if deemed necessary or appropriate by its Board of Directors,
issue Right Certificates representing the appropriate number of Rights in
connection with such issuance or sale; PROVIDED, HOWEVER, that (i) no such Right
Certificate shall be issued if, and to the extent that, the Company shall be
advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the Person to whom such
Right Certificate would be issued, and (ii) no such Right Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

          Section 24.  REDEMPTION AND TERMINATION.  (a) The Board of Directors
of the Company may, at its option, at any time prior to the earlier of (i) such
time as a Person becomes an Acquiring Person and (ii) the Expiration Date, order
the redemption of all, but not fewer than all, the then outstanding Rights at
the Redemption Price (the date of such redemption being the "Redemption Date"),
and the Company, at its option, may pay the Redemption Price either in cash or
Capital Shares or other securities of the Company deemed by the Board of
Directors of the Company, in the exercise of its sole discretion, to be at least
equivalent in value to the Redemption Price.

          (b)  Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights, and without any further action
and without any notice,

                                       25

 
the right to exercise the Rights will terminate and the only right thereafter of
the holders of Rights shall be to receive the Redemption Price.  Within 10
Business Days after the action of the Board of Directors of the Company ordering
the redemption of the Rights, the Company shall give notice of such redemption
to the holders of the then outstanding Rights by mailing such notice to all such
holders at their last addresses as they appear upon the registry books of the
Rights Agent or, prior to the Distribution Date, on the registry books of the
transfer agent for the Capital Shares.  Each such notice of redemption will
state the method by which payment of the Redemption Price will be made.  The
notice, if mailed in the manner herein provided, shall be conclusively presumed
to have been duly given, whether or not the holder of Rights receives such
notice.  In any case, failure to give such notice by mail, or any defect in the
notice, to any particular holder of Rights shall not affect the sufficiency of
the notice to other holders of Rights.

          Section 25.  NOTICES.  Notices or demands authorized by this Agreement
to be given or made by the Rights Agent or by the holder of a Right Certificate
(or, prior to the Distribution Date, of the Capital Shares) to or on the Company
shall be sufficiently given or made if sent by first-class mail, postage
prepaid, addressed (until another address is filed in writing with the Rights
Agent) as follows:

          The Safety Fund Corporation
          470 Main Street
          Fitchburg, Massachusetts 01420
          Attention of Chief Executive Officer

                               TERMS OF SERIES A
                           PARTICIPATING CUMULATIVE
                              PREFERRED STOCK OF 
                          THE SAFETY FUND CORPORATION

          Section 1.  DESIGNATION AND NUMBER OF SHARES.  The shares of such
series shall be designated as "Series A Participating Cumulative Preferred
Stock" (the "Series A Preferred Stock"), par value $10.00 per share.  The number
of shares initially constituting the Series A Preferred Stock shall be 3,200;
PROVIDED, HOWEVER, that, if more than a total of 3,200 shares of Series A
Preferred Stock shall be issuable upon the exercise of Rights (the "Rights")
issued pursuant to the Rights Agreement dated as of January 5, 1996, between the
Corporation and Fleet National Bank of Massachusetts, a national banking
association, as Rights Agent (the "Rights Agreement"), the Board of Directors of
the Corporation, pursuant to Section 26 of the Business Corporation Law of the
Commonwealth of Massachusetts, shall direct by resolution or resolutions that a
certificate be properly executed, acknowledged, filed and recorded, in
accordance with the provisions of said Section 26 thereof, providing for the
total number of shares of Series A Preferred Stock authorized to be issued to be
increased (to the extent that the Articles of Organization then permits) to the
largest number of whole shares (rounded up to the nearest whole number) issuable
upon exercise of such Rights.

          Section 2.  DIVIDENDS OR DISTRIBUTIONS.  (a) Subject to the prior and
superior rights of the holders of shares of any other series of Preferred Stock
or other class of capital stock of the Corporation ranking prior and superior to
the shares of Series A Preferred Stock with respect to dividends, the holders of
shares of the Series A Preferred Stock shall be entitled to receive, when, as
and if declared by the Board of Directors, out of the assets of the Corporation
legally available therefor, (1) quarterly dividends payable in cash on the last
day of each fiscal quarter in each year, or such other dates as the Board of
Directors of the Corporation shall approve (each such date being referred to
herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or a
fraction of a share of Series A Preferred Stock, in the amount of $10.00 per
whole share (rounded to the nearest cent) less the amount of all cash dividends
declared on the Series A Preferred Stock pursuant to the following clause (2)
since the immediately preceding Quarterly Dividend Payment Date or, with respect
to the first Quarterly Dividend Payment Date, since the first issuance of any
share or fraction of a share of Series A Preferred Stock (the total of which
shall not, in any event, be less than zero) and (2) dividends payable in cash on
the payment date for each cash dividend declared on the Common Stock in an
amount per whole share (rounded to the nearest cent) equal to the Formula Number
(as hereinafter defined) then in effect times the cash dividends then to be paid
on each share of Common Stock.  In addition, if the Corporation shall pay any
dividend or make any distribution on the Common Stock payable in assets,
securities or other forms of noncash consideration (other than dividends or
distributions solely in shares of Common Stock), then, in each such case, the
Corporation shall simultaneously pay or make on each outstanding whole share of
Series A Preferred Stock a dividend or distribution in like kind equal to the
Formula Number then in effect times such dividend or distribution on each share

                                      A-1

 
of the Common Stock.  As used herein, the "Formula Number" shall be 1,000;
PROVIDED, HOWEVER, that if at any time after January 5, 1996, the Corporation
shall (i) declare or pay any dividend on the Common Stock payable in shares of
Common Stock or make any distribution on the Common Stock in shares of Common
Stock, (ii) subdivide (by a stock split or otherwise) the outstanding shares of
Common Stock into a larger number of shares of Common Stock or (iii) combine (by
a reverse stock split or otherwise) the outstanding shares of Common Stock into
a smaller number of shares of Common Stock, then in each such event the Formula
Number shall be adjusted to a number determined by multiplying the Formula
Number in effect immediately prior to such event by a fraction, the numerator of
which is the number of shares of Common Stock that are outstanding immediately
after such event and the denominator of which is the number of shares of Common
Stock that are outstanding immediately prior to such event (and rounding the
result to the nearest whole number); and PROVIDED FURTHER, that, if at any time
after January 5, 1996, the Corporation shall issue any shares of its capital
stock in a merger, reclassification, or change of the outstanding shares of
Common Stock, then in each such event the Formula Number shall be appropriately
adjusted to reflect such merger, reclassification or change so that each share
of Series A Preferred Stock continues to be the economic equivalent of a Formula
Number of shares of Common Stock prior to such merger, reclassification or
change.

          (b)    The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in Section 2(a) immediately prior to or at
the same time it declares a dividend or distribution on the Common Stock(other
than a dividend or distribution solely in shares of Common Stock); PROVIDED,
HOWEVER, that, in the event no dividend or distribution (other than a dividend
or distribution in shares of Common Stock) shall have been declared on the
Common Stock during the period between any Quarterly Dividend Payment Date and
the next subsequent Quarterly Dividend Payment Date, a dividend of $10.00 per
share on the Series A Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.  The Board of Directors may fix a
record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive a dividend or distribution declared thereon, which
record date shall be the same as the record date for any corresponding dividend
or distribution on the Common Stock.

          (c)    Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from and after the Quarterly
Dividend Payment Date next preceding the date of original issue of such shares
of Series A Preferred Stock; PROVIDED, HOWEVER, that dividends on such shares
which are originally issued after the record date for the determination of
holders of shares of Series A Preferred Stock entitled to receive a quarterly
dividend and on or prior to the next succeeding Quarterly Dividend Payment Date
shall begin to accrue and be cumulative from and after such Quarterly Dividend
Payment Date. Notwithstanding the foregoing, dividends on shares of Series A
Preferred Stock which are originally issued prior to the record date for the
determination of holders of shares of Series A Preferred Stock entitled to
receive a quarterly dividend on the first Quarterly Dividend Payment Date shall
be calculated as if cumulative from and after the last day of the fiscal quarter
next preceding the date of original issuance of such shares. Accrued but unpaid
dividends shall not bear interest. Dividends paid on the shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and

                                      A-2

 
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding.

          (d)    So long as any shares of the Series A Preferred Stock are
outstanding, no dividends or other distributions shall be declared, paid or
distributed, or set aside for payment or distribution, on the Common Stock
unless, in each case, the dividend required by this Section 2 to be declared on
the Series A Preferred Stock shall have been declared.

          (e)    The holders of the shares of Series A Preferred Stock shall not
be entitled to receive any dividends or other distributions except as provided
herein.

          Section 3. VOTING RIGHTS.  The holders of shares of Series A Preferred
Stock shall have the following voting rights:

          (a)    Each holder of Series A Preferred Stock shall be entitled to a
number of votes equal to the Formula Number then in effect, for each share of
Series A Preferred Stock held of record on each matter on which holders of the
Common Stock or stockholders generally are entitled to vote, multiplied by the
maximum number of votes per share which any holder of the Common Stock or
stockholders generally then have with respect to such matter (assuming any
holding period or other requirement to vote a greater number of shares is
satisfied).

          (b)    Except as otherwise provided herein or by applicable law, the
holders of shares of Series A Preferred Stock and the holders of shares of
Common Stock shall vote together as one class for the election of directors of
the Corporation and on all other matters submitted to a vote of stockholders of
the Corporation.

          (c)    If, at the time of any annual meeting of stockholders for the
election of directors, the equivalent of six quarterly dividends (whether or not
consecutive) payable on any share or shares of Series A Preferred Stock are in
default, the number of directors constituting the Board of Directors of the
Corporation shall be increased by two.  In addition to voting together with the
holders of Common Stock for the election of other directors of the Corporation,
the holders of record of the Series A Preferred Stock, voting separately as a
class to the exclusion of the holders of Common Stock, shall be entitled at said
meeting of stockholders (and at each subsequent annual meeting of stockholders),
unless all dividends in arrears have been paid or declared and set apart for
payment prior thereto, to vote for the election of two directors of the
Corporation, the holders of any Series A Preferred Stock being entitled to cast
a number of votes per share of Series A Preferred Stock equal to the Formula
Number.  Until the default in payments of all dividends which permitted the
election of said directors shall cease to exist, any director who shall have
been so elected pursuant to the next preceding sentence may be removed at any
time, either with or without cause, only by the affirmative vote of the holders
of the shares of Series A Preferred Stock at the time entitled to cast a
majority of the votes entitled to be cast for the election of any such director
at a special meeting of such holders called for that purpose, and any vacancy
thereby created may be filled by the vote of such holders.  If and when such
default shall cease to exist, the holders of the Series A Preferred Stock shall
be divested of the foregoing special voting rights, subject to revesting in the
event of each and every subsequent like default in payments

                                      A-3

 
of dividends.  Upon the termination of the foregoing special voting rights, the
terms of office of all persons who may have been elected directors pursuant to
said special voting rights shall forthwith terminate, and the number of
directors constituting the Board of Directors shall be reduced by two.  The
voting rights granted by this Section 3(c) shall be in addition to any other
voting rights granted to the holders of the Series A Preferred Stock in this
Section 3.

          (d)    Except as provided herein, in Section 11 or by applicable law,
holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for authorizing or taking
any corporate action.

          Section 4. CERTAIN RESTRICTIONS.  (a) Whenever quarterly dividends or
other dividends or distributions payable on the Series A Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of Series
A Preferred Stock outstanding shall have been paid in full, the Corporation
shall not

          (i)    declare or pay dividends on, make any other distributions on,
     or redeem or purchase or otherwise acquire for consideration any shares of
     stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Preferred Stock;

          (ii)   declare or pay dividends on or make any other distributions on
     any shares of stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series A Preferred Stock,
     except dividends paid ratably on the Series A Preferred Stock and all such
     parity stock on which dividends are payable or in arrears in proportion to
     the total amounts to which the holders of all such shares are then
     entitled;

          (iii)  redeem or purchase or otherwise acquire for consideration
     shares of any stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series A Preferred Stock;
     PROVIDED that the Corporation may at any time redeem, purchase or otherwise
     acquire shares of any such parity stock in exchange for shares of any stock
     of the Corporation ranking junior (either as to dividends or upon
     dissolution, liquidation or winding up) to the Series A Preferred Stock; or

          (iv)   purchase or otherwise acquire for consideration any shares of
     Series A Preferred Stock, or any shares of stock ranking on a parity with
     the Series A Preferred Stock, except in accordance with a purchase offer
     made in writing or by publication (as determined by the Board of Directors)
     to all holders of such shares upon such terms as the Board of Directors,
     after consideration of the respective annual dividend rates and other
     relative rights and preferences of the respective series and classes, shall
     determine in good faith will result in fair and equitable treatment among
     the respective series or classes.

                                      A-4

 
          (b)    The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (a) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

          Section 5.  LIQUIDATION RIGHTS.  Upon the liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, no distribution
shall be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received an amount equal to the 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 (x) $100.00 per whole share
or (y) an aggregate amount per share equal to the Formula Number then in effect
times the aggregate amount to be distributed per share to holders of Common
Stock or (2) to the holders of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with the Series A Preferred
Stock, except distributions made ratably on the Series A Preferred Stock and all
other such parity stock in proportion to the total amounts to which the holders
of all such shares are entitled upon such liquidation, dissolution or winding
up.

          Section 6.  CONSOLIDATION, MERGER, ETC..  In case the Corporation
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other stock
or securities, cash or any other property, then in any such case the then
outstanding shares of Series A Preferred Stock shall at the same time be
similarly exchanged or changed into an amount per share equal to the Formula
Number then in effect times the aggregate amount of stock, securities, cash or
any other property (payable in kind), as the case may be, into which or for
which each share of Common Stock is exchanged or changed.  In the event both
this Section 6 and Section 2 appear to apply to a transaction, this Section 6
will control.

          Section 7. NO REDEMPTION; NO SINKING FUND. (a) The shares of Series A
Preferred Stock shall not be subject to redemption by the Corporation or at the
option of any holder of Series A Preferred Stock; PROVIDED, HOWEVER, that the
Corporation may purchase or otherwise acquire outstanding shares of Series A
Preferred Stock in the open market or by offer to any holder or holders of
shares of Series A Preferred Stock.

          (b)    The shares of Series A Preferred Stock shall not be subject to
or entitled to the operation of a retirement or sinking fund.

          Section 8. RANKING.  The Series A Preferred Stock shall rank junior to
all other series of Preferred Stock of the Corporation, unless the Board of
Directors shall specifically determine otherwise in fixing the powers,
preferences and relative, participating, optional and other special rights of
the shares of such series and the qualifications, limitations and restrictions
thereof.

          Section 9. FRACTIONAL SHARES.  The Series A Preferred Stock shall be
issuable upon exercise of the Rights issued pursuant to the Rights Agreement in
whole shares or in any fraction of a share that is one one-thousandth (1/1000th)
of a share or any integral

                                      A-5

 
multiple of such fraction which shall entitle the holder, in proportion to such
holder's fractional shares, to receive dividends, exercise voting rights,
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Stock.  In lieu of fractional shares, the
Corporation, prior to the first issuance of a share or a fraction of a share of
Series A Preferred Stock, may elect (1) to make a cash payment as provided in
the Rights Agreement for fractions of a share other than one one-thousandth
(1/1000th) of a share or any integral multiple thereof or (2) to issue
depository receipts evidencing such authorized fraction of a share of Series A
Preferred Stock pursuant to an appropriate agreement between the Corporation and
a depository selected by the Corporation; PROVIDED that such agreement shall
provide that the holders of such depository receipts shall have all the rights,
privileges and preferences to which they are entitled as holders of the Series A
Preferred Stock.

          Section 10.  REACQUIRED SHARES.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock, without designation as to series until such shares
are once more designated as part of a particular series by the Board of
Directors pursuant to the provisions of Section 2 of Article IV of the Articles
of Organization.

          Section 11.   AMENDMENT.  None of the powers, preferences and
relative, participating, optional and other special rights of the Series A
Preferred Stock as provided herein or in the Certificate of Incorporation shall
be amended in any manner which would alter or change the powers, preferences,
rights or privileges of the holders of Series A Preferred Stock so as to affect
them adversely without the affirmative vote of the holders of at least 66-2/3%
of the outstanding shares of Series A Preferred Stock, voting as a separate
class; PROVIDED, HOWEVER, that no such amendment approved by the holders of at
least 66-2/3% of the outstanding shares of Series A Preferred Stock shall be
deemed to apply to the powers, preferences, rights or privileges of any holder
of shares of Series A Preferred Stock originally issued upon exercise of the
Rights after the time of such approval without the approval of such holder.

          DEFINED IN THE RIGHTS AGREEMENT) AND BY ANY SUBSEQUENT HOLDER OF SUCH
          RIGHTS ARE NULL AND VOID AND NONTRANSFERABLE.


                               Right Certificate

                            SAFETY FUND CORPORATION


          This certifies that _________________________, or registered assigns,
is the registered owner of the number of Rights set forth above, each of which
entitles the owner, thereof, subject to the terms, provisions and conditions of
the Rights Agreement dated as of January 5, 1996, (the "Rights Agreement"),
between Safety Fund Corporation, a Massachusetts corporation (the "Company"),
and Fleet National Bank of Massachusetts, a national banking association, as
Rights Agent (the "Rights Agent"), unless the Rights evidenced hereby shall have
been previously redeemed by the Company, to purchase from the Company at any
time after the Distribution Date (as defined in the Rights Agreement) and prior
to 5:00 p.m., Boston, Massachusetts time, on the 10th anniversary of the date of
the Rights Agreement (the "Expiration Date"), at the office of the Rights Agent,
or its successors as Rights Agent, in Hartford, Connecticut one one-thousandth
(1/1000th) of a fully paid, nonassessable share of Series A Participating
Cumulative Preferred Stock, par value $10.00 per share, of the Company (the
"Preferred Shares"), at a purchase price per one one-thousandth (1/1000th) of a
share equal to $65 (the "Purchase Price") payable in cash, upon presentation and
surrender of this Right Certificate with the Form of Election to Purchase duly
executed.

          The Purchase Price and the number and kind of shares which may be
purchased upon exercise of each Right evidenced by this Right Certificate, as
set forth above, are the Purchase Price and the number and kind of shares which
may be so purchased as of January 5, 1996.  As provided in the Rights Agreement,
the Purchase Price and the number and kind of shares which may be purchased upon
the exercise of each Right

                                      B-1

 
evidenced by this Right Certificate are subject to modification and adjustment
upon the happening of certain events.

          If the Rights evidenced by this Right Certificate are at any time
beneficially owned by an Acquiring Person or an Affiliate or Associate of an
Acquiring Person (as such terms are defined in the Rights Agreement), such
Rights shall be null and void and nontransferable and the holder of any such
Right (including any purported transferee or subsequent holder) shall not have
any right to exercise or transfer any such Right.

          This Right Certificate is subject to all the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
reference to the Rights Agreement is hereby made for a full description of the
rights, limitations of rights, obligations, duties and immunities hereunder of
the Rights Agent, the Company and the holders of the Right Certificates.
Copies of the Rights Agreement are on file at the above-mentioned office of the
Rights Agent and are also available from the Company upon written request.

          This Right Certificate, with or without other Right Certificates, upon
surrender at the stock transfer or corporate trust office of the Rights Agent,
may be exchanged for another Right Certificate or Right Certificates of like
tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number and kind of shares as the Rights evidenced by the Right
Certificate or Right Certificates surrendered shall entitle such holder to
purchase.  If this Right Certificate shall be exercised in part, the holder
shall be entitled to receive upon surrender hereof another Right Certificate or
Right Certificates for the number of whole Rights not exercised.

          Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Right Certificate may be redeemed by the Company at its option
at a redemption price (in cash or shares of Common Stock or other securities of
the Company deemed by the Board of Directors to be at least equivalent in value)
of $.01 per Right (which amount shall be subject to adjustment as provided in
the Rights Agreement) at any time prior to the earlier of (i) such time as a
Person becomes an Acquiring Person and (ii) the Expiration Date.

          The Company may, but shall not be required to, issue fractions of
Preferred Shares or distribute certificates which evidence fractions of
Preferred Shares upon the exercise of any Right or Rights evidenced hereby.  In
lieu of issuing fractional shares, the Company may elect to make a cash payment
as provided in the Rights Agreement for fractions of a share other than one one-
thousandth (1/1000th) of a share or any integral multiple thereof or to issue
certificates or utilize a depository arrangement as provided in the terms of the
Rights Agreement and the Preferred Shares.

          No holder of this Right Certificate shall be entitled to vote or
receive dividends or be deemed for any purpose the holder of the Preferred
Shares or of any other securities of the Company which may at any time be
issuable on the exercise hereof, nor shall anything contained in the Rights
Agreement or herein be construed to confer upon the holder hereof, as such, any
of the rights of a stockholder of the Company, including, without limitation,
any right to vote for the election of directors or upon any matter submitted to

                                      B-2

 
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in the Rights Agreement), or to receive
dividends or other distributions or subscription rights, or otherwise, until the
Right or Rights evidenced by this Right Certificate shall have been exercised as
provided in accordance with the provisions of the Rights Agreement.

          This Right Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Rights Agent.

          WITNESS the facsimile signature of the proper officers of the Company
and its corporate seal.
