Item 1.          Description of Registrant's Securities to be Registered.

                 On October 15, 1996, the Board of Directors of Mellon Bank
Corporation, a Pennsylvania corporation (the "Company"), declared a dividend
payable October 31, 1996 of one right (a "Right") for each outstanding share
of common stock, par value $.50 per share ("Common Stock"), of the Company held
of record at the close of business on October 31, 1996 (the "Record Time"), or
issued thereafter and prior to the Separation Time (as hereinafter defined) and
thereafter pursuant to options and convertible securities outstanding at the
Separation Time.  The Rights will be issued pursuant to a Shareholder
Protection Rights Agreement, dated as of October 15, 1996 (the "Rights
Agreement"), between the Company and Mellon Bank, N.A., as Rights Agent (the
"Rights Agent").  Each Right entitles its registered holder to purchase from
the Company, after the Separation Time, one one-hundredth of a share of
Participating Preferred Stock, par value $1.00 per share ("Participating
Preferred Stock"), for $225 (the "Exercise Price"), subject to adjustment.

                 The Rights will be evidenced by the Common Stock certificates
until the close of business on the earlier of (either, the "Separation Time")
(i) the tenth Business Day (or such later date as the Board of Directors of the
Company may from time to time fix by resolution adopted prior to the Separation
Time that would otherwise have occurred) after the date on which any Person
commences a tender or exchange offer which, if consummated, would result in
such Person's becoming an Acquiring Person and (ii) the first date (the
"Flip-in Date") of public announcement by the Company that a Person (as defined
in the Rights Agreement) has become an Acquiring Person, other than as the
result of a Flip-over Transaction or Event (as defined below); provided that,
if the foregoing results in the Separation Time being prior to the Record Time,
the Separation Time shall be the Record Time and provided further, that, if any
tender or exchange offer referred to in clause (i) of this definition is
cancelled, terminated or otherwise withdrawn prior to the Separation Time
without the purchase of any shares of Common Stock pursuant thereto, such offer
shall be deemed, for purposes of this definition, never to have been made.  An
Acquiring Person is any Person who is a Beneficial Owner (as defined in the
Rights Agreement) of 15% or more of the outstanding shares of Common Stock, par
value $.50 per share, of the Company (the "Common Stock"), but such term does
not include (i) any Person who is the Beneficial Owner of





<PAGE>   3
15% or more of the outstanding shares of Common Stock on October 15, 1996 or
who shall become the Beneficial Owner of 15% or more of the outstanding shares
of Common Stock solely as a result of an acquisition by the Company of shares
of Common Stock, until such time hereafter or thereafter as such Person shall
become the Beneficial Owner (other than by means of a stock dividend or stock
split or by purchase from the Company) of any additional shares of Common
Stock; (ii) any Person who becomes the Beneficial Owner of 15% or more of the
outstanding shares of Common Stock but who acquired Beneficial Ownership of
shares of Common Stock without any plan or intention to seek or affect control
of the Company, if such Person promptly enters into an irrevocable commitment
to divest, and thereafter promptly divests (without exercising or retaining any
power, including voting, with respect to such shares), sufficient shares of
Common Stock (or securities convertible into, exchangeable into or exercisable
for Common Stock) so that such Person ceases to be the Beneficial Owner of 15%
or more of the outstanding shares of Common Stock; (iii) any Person who
Beneficially Owns shares of Common Stock consisting solely of one or more of
(A) shares of Common Stock Beneficially Owned pursuant to the grant or exercise
of an option granted to such Person (an "Option Holder") by the Company in
connection with an agreement to merge with, or acquire, the Company entered
into prior to a Flip-in Date, (B) shares of Common Stock (or securities
convertible into, exchangeable into or exercisable for Common Stock),
Beneficially Owned by such Option Holder or its Affiliates or Associates at the
time of grant of such option, (C) shares of Common Stock (or securities
convertible into, exchangeable into or exercisable for Common Stock) acquired
by Affiliates or Associates of such Option Holder after the time of such grant
which, in the aggregate, amount to less than 1% of the outstanding shares of
Common Stock, and (D) shares of Common Stock (or securities convertible into,
exchangeable into or exercisable for Common Stock) which are held by such
Option Holder in trust accounts, managed accounts and the like or otherwise
held in a fiduciary capacity, that are beneficially owned by third Persons who
are not Affiliates or Associates of such Option Holder or acting together with
such Option Holder to hold such shares, or which are held by such Person in
respect of a debt previously contracted; and (iv) the Company, any wholly-owned
Subsidiary of the Company or an employee stock ownership plan or other employee
benefit plan of the Company or a wholly-owned subsidiary of the Company or any
employee stock benefit trust established by the Company. The
Rights Agreement provides that, until the Separation Time, the Rights will be
transferred with and only with the Common Stock. Common Stock certificates
issued after the Record Time but prior to the Separation Time shall evidence
one Right for each share of Common Stock represented thereby and shall contain
a legend incorporating by reference the terms of the Rights Agreement (as such
may





<PAGE>   4
be amended from time to time).  Notwithstanding the absence of the
aforementioned legend, certificates evidencing shares of Common Stock
outstanding at the Record Time shall also evidence one Right for each share of
Common Stock evidenced thereby.  Promptly following the Separation Time,
separate certificates evidencing the Rights ("Rights Certificates") will be
mailed to holders of record of Common Stock at the Separation Time.

                 The Rights will not be exercisable until after the Separation
Time.  The Rights will expire on the earliest of (i) the Exchange Time, (ii)
the Redemption Time, (iii) the close of business on the tenth anniversary of
the Record Time and (iv) immediately prior to the effective time of a
consolidation, merger or share exchange of the Company (A) into another
corporation or (B) with another corporation in which the Company is the
surviving corporation but Common Stock is converted into cash and/or securities
of another corporation, in either case pursuant to an agreement entered into by
the Company prior to a Stock Acquisition Date (any such time, the "Expiration
Time"), and no Person shall thereafter have any rights pursuant to the Rights
Agreement or any Right.

                 The Exercise Price and the number of Rights outstanding, or in
certain circumstances the securities purchasable upon exercise of the Rights,
are subject to adjustment from time to time to prevent dilution in the event of
a Common Stock dividend on, or a subdivision or a combination into a smaller
number of shares of, Common Stock, or the issuance or distribution of any
securities or assets in respect of, in lieu of or in exchange for Common Stock.

                 In the event that prior to the Expiration Time a Flip-in Date
shall occur, the Company shall take such action as shall be necessary to ensure
and provide that each Right (other than Rights Beneficially Owned by the
Acquiring Person or any affiliate or associate thereof, which Rights shall
become void) shall constitute the right to purchase from the Company, upon the
exercise thereof in accordance with the terms of the Rights Agreement, that
number of shares of Common Stock or Participating Preferred Stock of the
Company having an aggregate Market Price (as defined in the Rights Agreement),
on the date of the public announcement of an Acquiring Person's becoming such
(the "Stock Acquisition Date") that gave rise to the Flip-in Date, equal to
twice the Exercise Price for an amount in cash equal to the then current
Exercise Price.  In addition, the Board of Directors of the Company may, at its
option, at any time after a Flip-in Date, to the fullest extent that





<PAGE>   5
applicable law would not prohibit Rights owned by Acquiring Persons or
Affiliates or Associates thereof becoming void pursuant to the provisions
thereof, elect to exchange all (but not less than all) the then outstanding
Rights for shares of Common Stock at an exchange ratio of one share of Common
Stock per Right, appropriately adjusted in order to protect the interests of
holders of Rights generally in the event that after the Separation Time an
event such as a stock dividend, stock split, reclassification or
recapitalization shall have occurred with respect to the Common Stock (such
exchange ratio, as adjusted from time to time, being hereinafter referred to as
the "Exchange Ratio").  Immediately upon the action of the Board of Directors
of the Company electing to exchange the Rights, without any further action and
without any notice, the right to exercise the Rights will terminate (the
"Termination Time") and each Right will thereafter represent only the right to
receive a number of shares of Common Stock equal to the Exchange Ratio.
Whenever the Company shall become obligated under the provisions described in
this paragraph to issue shares of Common Stock upon exercise of or in exchange
for Rights, the Company, at its option, may substitute therefor shares of
Participating Preferred Stock, at a ratio of one one-hundredth of a share of
Participating Preferred Stock for each share of Common Stock so issuable.

                 The Rights Agreement provides that prior to the Expiration
Time, the Company shall not enter into any agreement with an Acquiring Person
with respect to, consummate or permit to occur any Flip-over Transaction or
Event (as defined below) unless and until it shall have entered into a
supplemental agreement with the Flip-over Entity (i.e., the Person issuing any
securities into which shares of Common Stock are being converted or exchanged
and, if no such securities are being issued, the other party to such Flip-over
Transaction or Event, or the Person receiving the greatest portion of the
assets or operating income or cash flow being transferred in a Flip-over
Transaction or Event), for the benefit of the holders of the Rights, providing
that, upon consummation or occurrence of the Flip-over Transaction or Event (i)
each Right shall thereafter constitute the right to purchase from the Flip-over
Entity, upon exercise thereof in accordance with the Rights Agreement, that
number of shares of Flip-over Stock (i.e., the capital stock with the greatest
voting power in respect of the election of directors of the Flip-over Entity)
of the Flip-over Entity having an aggregate Market Price on the date of
consummation or occurrence of such Flip-over Transaction or Event equal to
twice the Exercise Price for an amount in cash equal to the Exercise Price and
(ii) the Flip-over Entity shall thereafter be liable for, and shall





<PAGE>   6
assume, by virtue of such Flip-over Transaction or Event and such supplemental
agreement, all the obligations and duties of the Company pursuant to the Rights
Agreement.  For purposes of the foregoing description, the term "Acquiring
Person" shall include any Acquiring Person and its Affiliates and Associates
(as such terms are defined in the Rights Agreement) counted together as a
single Person.

                 A "Flip-over Transaction or Event" is a transaction or series
of transactions on or after a Flip-in Date in which, directly or indirectly,
(A) the Company shall consolidate or merge with, or participate in a share
exchange with any other Person if, at the time of the consolidation, merger or
share exchange or at the time the Company enters into any agreement with
respect to any such consolidation, merger or share exchange, the Acquiring
Person controls the Board of Directors of the Company and either (i) any terms
of or arrangement concerning the treatment of shares of capital stock in such
consolidation, merger or share exchange relating to the Acquiring Person is not
identical to the terms and arrangements relating to other holders of the Common
Stock or (ii) the Person with whom the transaction or series of transactions
occurs is the Acquiring Person or an Affiliate or Associate of the Acquiring
Person, or (B) the Company shall sell or otherwise transfer (or one or more of
its subsidiaries shall sell or otherwise transfer) assets of the Company and
its Subsidiaries (taken as a whole) to any Person (other than the Company or
one or more of its wholly-owned subsidiaries) or to two or more such Persons
which are Affiliates or Associates or otherwise acting in concert, if, at the
time of the entry by the Company (or any such Subsidiary) into an agreement
with respect to such sale or transfer of assets, the Acquiring Person controls
the Board of Directors of the Company.  For purposes of the foregoing
description, (x) the term "Acquiring Person" includes any Acquiring Person and
its Affiliates and Associates (other than the Company), and (y) an Acquiring
Person shall be deemed to control the Company's Board of Directors when,
following a Flip-in Date, the persons who were directors of the Company (or
persons nominated and/or appointed as directors by vote of a majority of such
persons) before the Stock Acquisition Date shall cease to constitute a majority
of the Company's Board of Directors.

                 The Rights Agreement provides that prior to the Expiration
Time, unless the Rights have been redeemed, the Company shall not enter into
any agreement with respect to, consummate or permit to occur any Flip-over
Transaction or Event if at the time thereof there are any rights, warrants or
securities outstanding or any other arrangements,





<PAGE>   7
agreements or instruments which would eliminate or otherwise diminish in any
material respect the benefits intended to be afforded by the Rights Agreement
to the holders of Rights upon consummation of such transaction.

                 The Board of Directors of the Company may, at its option, at
any time prior to the close of business on the Flip-In Date, elect to redeem
all (but not less than all) the then outstanding Rights at the Redemption Price
and the Company, at its option, may pay the Redemption Price either in cash or
shares of Common Stock or other securities of the Company deemed by the Board
of Directors, in the exercise of its sole discretion, to be at least equivalent
in value to the Redemption Price.  Immediately upon the action of the Board of
Directors of the Company electing to redeem the Rights (or, if the resolution
of the Board of Directors electing to redeem the Rights states that the
redemption will not be effective until the occurrence of a specified future
time or event, upon the occurrence of such future time or event), without any
further action and without any notice, the right to exercise the Rights will
terminate and each Right will thereafter represent only the right to receive
the Redemption Price in cash or securities, as determined by the Board of
Directors.  Promptly after the Rights are redeemed, the Company shall give
notice of such redemption to the Rights Agent and the holders of the then
outstanding Rights.

                 The holders of Rights will, solely by reason of their
ownership of Rights, have no rights as shareholders of the Company, including,
without limitation, the right to vote or to receive dividends.

                 The Rights will not prevent a takeover of the Company.
However, the Rights may cause substantial dilution to a person or group that
acquires 15% or more of the Common Stock unless the Rights are first redeemed
by the Board of Directors of the Company.  Nevertheless, the Rights should not
interfere with a transaction that is in the best interests of the Company and
its shareholders because the Rights can be redeemed on or prior to the close of
business on the Flip-in Date, before the consummation of such transaction.

                 As of October 15, 1996 there were 147,165,480 shares of Common
Stock issued (of which 129,538,059 shares were outstanding and 17,627,421
shares were held in treasury).  As long as the Rights are attached to the
Common Stock, the Company will issue one Right with each new share of Common
Stock so that all such shares will have Rights attached.

                              W I T N E S S E T H:

                  WHEREAS, the Board of Directors of the Company has (a)
authorized and declared a dividend of one right ("Right") in respect of each
share of Common Stock (as hereinafter defined) held of record as of the close of
business on October 31, 1996 (the "Record Time") and (b) as provided in Section
2.4, authorized the issuance of one Right in respect of each share of Common
Stock issued or sold by the Company after the Record Time and prior to the
Separation Time (as hereinafter defined) and, to the extent provided in Section
5.3, each share of Common Stock issued or sold by the Company after the
Separation Time;

                  WHEREAS, subject to the terms and conditions hereof, each
Right entitles the holder thereof, after the Separation Time, to purchase
securities or assets of the Company (or, in certain cases, securities of certain
other entities) pursuant to the terms and subject to the conditions set forth
herein; and

                  WHEREAS, the Company desires to appoint the Rights Agent to
act on behalf of the Company, and the Rights Agent is willing so to act, in
connection with the issuance, transfer, exchange and replacement of Rights
Certificates (as hereinafter defined), the exercise of Rights and other matters
referred to herein;

                  NOW, THEREFORE, in consideration of the premises and the
respective agreements set forth herein and intending to be legally bound hereby,
the parties hereby agree as follows:

                                    ARTICLE I

                                   DEFINITIONS

                  1.1 Certain Definitions. For purposes of this Agreement, the
following terms have the meanings indicated:

                  "Acquiring Person" shall mean any Person who is a Beneficial

         outstanding shares of Common Stock on October 15, 1996 or who shall
         become the Beneficial Owner of 15% or more of the outstanding shares of
         Common Stock solely as a result of an acquisition by the Company of
         shares of Common Stock, until such time hereafter or thereafter as such
         Person shall become the Beneficial Owner (other than by means of a
         stock dividend or stock split or by purchase from the Company) of any
         additional shares of Common Stock;

            (ii) any Person who becomes the Beneficial Owner of 15% or more of
         the outstanding shares of Common Stock but who acquired Beneficial
         Ownership of shares of Common Stock without any plan or intention to
         seek or affect control of the Company, if such Person promptly enters
         into an irrevocable commitment to divest, and thereafter promptly
         divests (without exercising or retaining any power, including voting,
         with respect to such shares), sufficient shares of Common Stock (or
         securities convertible into, exchangeable into or exercisable for
         Common Stock) so that such Person ceases to be the Beneficial Owner of
         15% or more of the outstanding shares of Common Stock;

             (iii) any Person who Beneficially Owns shares of Common Stock
         consisting solely of one or more of (A) shares of Common Stock

         Common Stock, and (D) shares of Common Stock (or securities convertible
         into, exchangeable into or exercisable for Common Stock) which are held
         by such Option Holder in trust accounts, managed accounts and the like
         or otherwise held in a fiduciary capacity, that are beneficially owned
         by third Persons who are not Affiliates or Associates of such Option
         Holder or acting together with such Option Holder to hold such shares,

         any employee stock ownership plan or other employee benefit plan of the
         Company or a wholly-owned subsidiary of the Company, or any employee   
         stock benefit trust established by the Company.

         
         
         

                  "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 under the Securities Exchange Act of 1934,
as such Rule is in effect on the date of this Agreement.

                  A Person shall be deemed the "Beneficial Owner", and to have
"Beneficial Ownership", of, and to "Beneficially Own", any securities as to
which such Person or any of such Person's Affiliates or Associates is or may be
deemed to be the beneficial owner pursuant to Rules 13d-3 and 13d-5 under the
Exchange Act, as such Rules are in effect on the date of this Agreement, as well
as any securities as to which such Person or any of such Person's Affiliates or
Associates has the right to become Beneficial Owner (whether such right is
exercisable immediately or only after the passage of time or the occurrence of
conditions) pursuant to any agreement, arrangement or understanding, 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, to have "Beneficial Ownership" of, or to
"Beneficially Own", any security (i) solely because such security has been
tendered pursuant to a tender or exchange offer made by such Person or any of
such Person's Affiliates or Associates until such tendered security is accepted
for payment or exchange, (ii) solely because such Person or any of such Person's
Affiliates or Associates has or shares the power to vote or direct the voting of
such security pursuant to a revocable proxy given in response to a public proxy
or consent solicitation made to more than ten holders of shares of a class of
stock of the Company registered under Section 12 of the Exchange Act and
pursuant to, and in accordance with, the applicable rules and regulations under
the Exchange Act, except if such power (or the arrangements relating thereto) is
then reportable under Item 6 of Schedule 13D under the Exchange Act (or any
similar provision of a comparable or successor report), or (iii) solely because
of the grant by the Company to such Person, in connection with the execution of
an agreement to acquire the Company, of options to acquire such security;
provided, further, that the Warburg Entities shall not be deemed to Beneficially
Own shares of Common Stock owned by their Associates (other than their
Affiliates, general partners, officers and directors), and such Associates
(other than such Affiliates, general partners, officers and directors) shall not
be deemed to Beneficially Own shares of Common Stock owned by the Warburg
Entities. Notwithstanding

                                       -3-
<PAGE>   7
the foregoing, no officer or director of the Company shall be deemed to
Beneficially Own any securities of any other Person by virtue of any actions
such officer or director takes in such capacity. For purposes of this Agreement,
in determining the percentage of the outstanding shares of Common Stock with

Person is deemed the Beneficial Owner shall be deemed outstanding.

                  "Business Day" shall mean any day other than a Saturday,
Sunday or a day on which banking institutions in The City of New York or the

further, that, if any tender or exchange offer referred to in clause (i) of this
definition is cancelled, terminated or otherwise withdrawn prior to the

                  2.2 Legend on Common Stock Certificates. Certificates for the
Common Stock issued after the Record Time but prior to the Separation Time shall
evidence one Right for each share of Common Stock represented thereby and shall
have impressed on, printed on, written on or otherwise affixed to them the
following legend:

         Until the Separation Time (as defined in the Rights Agreement referred
         to below), this certificate also evidences and entitles the holder
         hereof to certain Rights as set forth in a Shareholder Protection
         Rights Agreement, dated as of October 15, 1996 (as such may be amended
         from time to time, the "Rights Agreement"), between Mellon Bank
         Corporation (the "Company") and Mellon Bank, N.A., as 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 may be redeemed, may become exercisable for securities or
         assets of the Company or securities of another entity, may be exchanged
         for shares of Common Stock or other securities or assets of the
         Company, may expire, may become void (if they are "Beneficially Owned"
         by an "Acquiring Person" or an Affiliate or Associate thereof, as such
         terms are defined in the Rights Agreement, or by any transferee of any
         of the foregoing) or may be evidenced by separate certificates and may
         no longer be evidenced by this certificate. The Company will mail or
         arrange for the mailing of a copy of the Rights Agreement to the holder
         of this certificate without charge after the receipt of a written
         request therefor.

Certificates representing shares of Common Stock that are issued and outstanding
at the Record Time shall evidence one Right for each share of Common Stock
evidenced thereby notwithstanding the absence of the foregoing legend.

                  2.3 Exercise of Rights; Separation of Rights. (a) Subject to
Sections 3.1, 5.1 and 5.10 and subject to adjustment as herein set forth, each
Right will entitle the holder thereof, after the Separation Time and prior to
the Expiration Time, to purchase, for the Exercise Price, one one-hundredth of a
share of Participating Preferred Stock.

                  (b) Until the Separation Time, (i) no Right may be exercised
and (ii) each Right will be evidenced by the certificate for the associated
share of Common Stock (together, in the case of certificates issued prior to the

                                       -9-
<PAGE>   13
Record Time, with the letter mailed to the record holder thereof pursuant to
Section 2.1) and will be transferable only together with, and will be
transferred by a transfer (whether with or without such letter) of, such
associated share. Notwithstanding any other provision of this Agreement, any
Rights held by the Company or any of its Subsidiaries (other than Rights held in
a fiduciary capacity or pursuant to any Employee Plans) shall not be exercisable
by the Company or any such Subsidiary.

                  (c) Subject to the terms and conditions hereof, after the
Separation Time and prior to the Expiration Time, the Rights (i) may be
exercised and (ii) may be transferred independent of shares of Common Stock.
Promptly following the Separation Time, the Rights Agent will mail to each
holder of record of Common Stock as of the Separation Time (other than any
Person whose Rights have become void pursuant to Section 3.1(b)), at such
holder's address as shown by the records of the Company (the Company hereby
agreeing to furnish copies of such records to the Rights Agent for this
purpose), (x) a certificate (a "Rights Certificate") in substantially the form
of Exhibit A hereto appropriately completed, representing the number of Rights
held by such holder at the Separation Time and having 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 Agreement, or as may be required to comply with any
law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any national securities exchange or quotation system on which the
Rights may from time to time be listed or traded, or to conform to usage, and
(y) a disclosure statement describing the Rights.

                  (d) Subject to the terms and conditions hereof, Rights may be
exercised on any Business Day after the Separation Time and prior to the
Expiration Time by submitting to the Rights Agent the Rights Certificate
evidencing such Rights with an Election to Exercise (an "Election to Exercise")
substantially in the form attached to the Rights Certificate duly completed,
accompanied by payment in cash, or by certified or official bank check or money
order payable to the order of the Company, of a sum equal to the Exercise Price
multiplied by the number of Rights being exercised and a sum sufficient to cover
any transfer tax or charge which may be payable in respect of any transfer
involved in the transfer or delivery of Rights Certificates or the issuance or
delivery of certificates for shares or depositary receipts (or both) in a name
other than that of the holder of the Rights being exercised.

                  (e) Upon receipt of a Rights Certificate, with an Election to
Exercise accompanied by payment as set forth in Section 2.3(d), and subject to
the terms and conditions hereof, the Rights Agent will thereupon promptly (i)(A)
requisition from a transfer agent stock certificates evidencing such number of
shares or other securities to be purchased (the Company hereby irrevocably
authorizing its transfer agents to comply with all such requisitions) and (B) if
the Company elects pursuant to Section 5.5 hereof not to issue certificates
representing fractional shares, requisition from the depositary selected by the
Company depositary receipts representing the fractional shares to be purchased
or requisition from the Company the amount of cash to be paid in lieu of
fractional shares in accordance with Section 5.5 and (ii) after receipt of such
certificates, depositary receipts and/or cash, deliver the same to or upon the
order of the registered holder of such Rights Certificate, registered (in the
case of certificates or depositary receipts) in such name or names as may be
designated by such holder.

                  (f) In case the holder of any Rights shall exercise less than
all the Rights evidenced by such holder's Rights Certificate, a new Rights
Certificate evidencing the Rights remaining unexercised will be issued by the
Rights Agent to such holder or to such holder's duly authorized assigns.

                  (g) The Company covenants and agrees that it will (i) cause to
be kept available until the Expiration Time out of its authorized and unissued
shares of capital stock a number of shares of Participating Preferred Stock that
will be sufficient to permit the exercise in full of all outstanding Rights;
(ii) take all such action as may be necessary to ensure that all shares
delivered upon exercise of Rights shall, at the time of delivery of the
certificates for such shares (subject to payment of the Exercise Price), be duly
and validly authorized, executed, issued and delivered and fully paid and
nonassessable; (iii) take all such action as may be necessary to comply with any
applicable requirements of the Securities Act of 1933 or the Exchange Act, and
the rules and regulations thereunder, and any other applicable law, rule or
regulation, in connection with the issuance of any shares upon exercise of
Rights; and (iv) pay when due and payable any and all federal and state transfer
taxes and charges which may be payable in respect of the original issuance or
delivery of the Rights Certificates or of any shares issued upon the exercise of
Rights, provided that the Company shall not be required to pay any transfer tax
or charge which may be payable in respect of any transfer involved in the
transfer or delivery of Rights Certificates or the issuance or delivery of
certificates for

                                      -11-
<PAGE>   15
shares in a name other than that of the holder of the Rights being transferred
or exercised.

                  2.4 Adjustments to Exercise Price; Number of Rights. (a) In
the event the Company shall at any time after the Record Time and prior to the
Separation Time (i) declare or pay a dividend on Common Stock payable in Common
Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the
outstanding Common Stock into a smaller number of shares of Common Stock, (x)
the Exercise Price in effect after such adjustment will be equal to the Exercise
Price in effect immediately prior to such adjustment divided by the number of
shares of Common Stock (the "Expansion Factor") that a holder of one share of
Common Stock immediately prior to such dividend, subdivision or combination
would hold thereafter as a result thereof and (y) each Right held prior to such
adjustment will become that number of Rights equal to the Expansion Factor, and
the adjusted number of Rights will be deemed to be distributed among the shares
of Common Stock with respect to which the original Rights were associated (if
they remain outstanding) and the shares issued in respect of such dividend,
subdivision or combination, so that each such share of Common Stock will have
exactly one Right associated with it. Each adjustment made pursuant to this
paragraph shall be made as of the payment or effective date for the applicable
dividend, subdivision or combination.

                  In the event the Company shall at any time after the Record
Time and prior to the Separation Time issue or sell any shares of Common Stock
otherwise than in a transaction referred to in the preceding paragraph, each
such share of Common Stock so issued or sold shall automatically have one new
Right associated with it, which Right shall be evidenced by the certificate
representing such share. To the extent provided in Section 5.3, Rights shall be
issued by the Company in respect of shares of Common Stock that are issued or
sold by the Company after the Separation Time.

                  (b) In the event the Company shall at any time after the
Record Time and prior to the Separation Time issue or distribute any securities
or assets in respect of, in lieu of or in exchange for Common Stock (other than
pursuant to a regular periodic cash dividend or a dividend paid solely in Common
Stock) whether by dividend, in a reclassification or recapitalization
(including any such transaction involving a merger, consolidation or share
exchange), or otherwise, the Company shall make such adjustments, if any, in the
Exercise Price, number of Rights and/or securities or other property purchasable
upon exercise of Rights as the Board of Directors of the Company, in its sole

                                      -12-
<PAGE>   16
discretion, may deem to be appropriate under the circumstances in order to
adequately protect the interests of the holders of Rights generally, and the
Company and the Rights Agent shall amend this Agreement as necessary to provide
for such adjustments.

                  (c) Each adjustment to the Exercise Price made pursuant to
this Section 2.4 shall be calculated to the nearest cent. Whenever an adjustment
to the Exercise Price is made pursuant to this Section 2.4, the Company shall
(i) promptly prepare a certificate setting forth such adjustment and a brief
statement of the facts accounting for such adjustment and (ii) promptly file
with the Rights Agent and with each transfer agent for the Common Stock a copy
of such certificate.

                  (d) Rights certificates shall represent the securities
purchasable under the terms of this Agreement, including any adjustment or
change in the securities purchasable upon exercise of the Rights, even though
such certificates may continue to express the securities purchasable at the time
of issuance of the initial Rights Certificates.

                  2.5 Date on Which Exercise is Effective. Each person in whose
name any certificate for shares is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the shares
represented thereby on the date upon which the Rights Certificate evidencing
such Rights was duly surrendered and payment of the Exercise Price for such
Rights (and any applicable taxes and other governmental charges payable by the
exercising holder hereunder) was made; provided, however, that if the
date of such surrender and payment is a date upon which the stock transfer 
books of the Company are closed, such person shall be deemed to have become 
the record holder of such shares on, and such certificate shall be dated,
the next succeeding Business Day on which the stock transfer books of the
Company are open.

                  2.6 Execution, Authentication, Delivery and Dating of Rights
Certificates. (a) The Rights Certificates shall be executed on behalf of the
Company by its Chairman of the Board, President, Chief Executive Officer or one
of its Vice Chairmen, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Rights Certificates may be manual or facsimile.

                  Rights Certificates bearing the manual or facsimile signatures
of individuals who were at any time the proper officers of the Company shall
bind the Company,

                                      -13-
<PAGE>   17
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the countersignature and delivery of such Rights Certificates.

                  Promptly after the Company learns of the Separation Time, the
Company will notify the Rights Agent of such Separation Time and will deliver
Rights Certificates executed by the Company to the Rights Agent for
countersignature, and, subject to Section 3.1(b), the Rights Agent shall
manually countersign and deliver such Rights Certificates to the holders of the
Rights pursuant to Section 2.3(c) hereof. No Rights Certificate shall be valid
for any purpose unless manually countersigned by the Rights Agent.

                  (b) Each Rights Certificate shall be dated the date of
countersignature thereof.

                  2.7 Registration, Registration of Transfer and Exchange. (a)
After the Separation Time, the Company will cause to be kept a register (the
"Rights Register") in which, subject to such reasonable regulations as it may
prescribe, the Company will provide for the registration and transfer of Rights.
The Rights Agent is hereby appointed "Rights Registrar" for the purpose of
maintaining the Rights Register for the Company and registering Rights and
transfers of Rights after the Separation Time as herein provided, provided that
the Rights Agent is hereby authorized to appoint ChaseMellon Shareholder
Services, L.L.C. as Rights Registrar (in which capacity such Rights Registrar
shall be entitled to the benefits of Article IV hereof as if it were Rights
Agent). In the event that the Rights Agent shall cease to be the Rights
Registrar, the Rights Agent will have the right to examine the Rights Register
at all reasonable times after the Separation Time.

                  After the Separation Time and prior to the Expiration Time,
upon surrender for registration of transfer or exchange of any Rights
Certificate, and subject to the provisions of Section 2.7(c) and (d), the
Company will execute, and the Rights Agent will countersign and deliver, in the
name of the holder or the designated transferee or transferees, as required
pursuant to the holder's instructions, one or more new Rights Certificates
evidencing the same aggregate number of Rights as did the Rights Certificate so
surrendered.

                  (b) Except as otherwise provided in Section 3.1(b), all Rights
issued upon any registration of transfer or exchange of Rights Certificates
shall be the valid obligations of the Company, and such Rights shall be entitled
to the same benefits under this Agreement as the

                                      -14-
<PAGE>   18
Rights surrendered upon such registration of transfer or exchange.

                  (c) Every Rights Certificate surrendered for registration of
transfer or exchange shall be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company or the Rights Agent,
as the case may be, duly executed by the holder thereof or such holder's
attorney duly authorized in writing. As a condition to the issuance of any new
Rights Certificate under this Section 2.7, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto.

                  (d) The Company shall not be required to register the transfer
or exchange of any Rights after such Rights have become void under Section
3.1(b), been exchanged under Section 3.1(c) or been redeemed or terminated under
Section 5.1.

                  2.8 Mutilated, Destroyed, Lost and Stolen Rights Certificates.
(a) If any mutilated Rights Certificate is surrendered to the Rights Agent prior
to the Expiration Time, then, subject to Sections 3.1(b), 3.1(c) and 5.1, the
Company shall execute and the Rights Agent shall countersign and deliver in
exchange therefor a new Rights Certificate evidencing the same number of Rights
as did the Rights Certificate so surrendered.

                  (b) If there shall be delivered to the Company and the Rights
Agent prior to the Expiration Time (i) evidence to their satisfaction of the
destruction, loss or theft of any Rights Certificate and (ii) such security or
indemnity as may be required by them to save each of them and any of their
agents harmless, then, subject to Sections 3.1(b), 3.1(c) and 5.1 and in the
absence of notice to the Company or the Rights Agent that such Rights
Certificate has been acquired by a bona fide purchaser, the Company shall
execute and upon its request the Rights Agent shall countersign and deliver, in
lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights
Certificate evidencing the same number of Rights as did the Rights Certificate
so destroyed, lost or stolen.

                  (c) As a condition to the issuance of any new Rights
Certificate under this Section 2.8, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the
Rights Agent) connected therewith.

                                      -15-
<PAGE>   19
                  (d) Every new Rights Certificate issued pursuant to this
Section 2.8 in lieu of any destroyed, lost or stolen Rights Certificate shall
evidence an original additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Rights Certificate shall be at any time
enforceable by anyone, and subject to Section 3.1(b), shall be entitled to all
the benefits of this Agreement equally and proportionately with any and all
other Rights duly issued hereunder.

                  2.9 Persons Deemed Owners. Prior to due presentment of a
Rights Certificate (or, prior to the Separation Time, the associated Common
Stock certificate) for registration of transfer, the Company, the Rights Agent
and any agent of the Company or the Rights Agent may deem and treat the person
in whose name such Rights Certificate (or, prior to the Separation Time, such
Common Stock certificate) is registered as the absolute owner thereof and of the
Rights evidenced thereby for all purposes whatsoever, including the payment of
the Redemption Price, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary. As used in this Agreement, unless the
context otherwise requires, the term "holder" of any Rights shall mean the
registered holder of such Rights (or, prior to the Separation Time, the
associated shares of Common Stock).

                  2.10 Delivery and Cancellation of Certificates. All Rights
Certificates surrendered upon exercise or for redemption, registration of
transfer or exchange shall, if surrendered to any person other than the Rights
Agent, be delivered to the Rights Agent and, in any case, shall be promptly
cancelled by the Rights Agent. The Company may at any time deliver to the Rights
Agent for cancellation any Rights Certificates previously countersigned and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Rights Certificates so delivered shall be promptly cancelled
by the Rights Agent. No Rights Certificates shall be countersigned in lieu of or
in exchange for any Rights Certificates cancelled as provided in this Section 
2.10, except as expressly permitted by this Agreement. The Rights Agent shall
destroy all cancelled Rights Certificates and deliver a certificate of
destruction to the Company.

                  2.11 Agreement of Rights Holders. Every holder of Rights by
accepting the same consents and agrees with the Company and the Rights Agent and
with every other holder of Rights that:

                  (a) prior to the Separation Time, each Right will be
         transferable only together with, and will be trans-


                                      -16-
<PAGE>   20
         ferred by a transfer of, the associated share of Common
         Stock;

                  (b) after the Separation Time, the Rights Certificates will be
         transferable only on the Rights Register as provided herein;

                  (c) prior to due presentment of a Rights Certificate (or,
         prior to the Separation Time, the associated Common Stock certificate)
         for registration of transfer, the Company, the Rights Agent and any
         agent of the Company or the Rights Agent may deem and treat the person
         in whose name the Rights Certificate (or, prior to the Separation Time,
         the associated Common Stock certificate) is registered as the absolute
         owner thereof and of the Rights evidenced thereby for all purposes
         whatsoever, and neither the Company nor the Rights Agent shall be
         affected by any notice to the contrary;

                  (d) Rights beneficially owned by certain Persons will, under
         the circumstances set forth in Section 3.1(b), become void; and

                  (e) this Agreement may be supplemented or amended from time to
         time pursuant to Section 2.4(b) or 5.4 hereof.

                                   ARTICLE III

                            ADJUSTMENTS TO THE RIGHTS
                      IN THE EVENT OF CERTAIN TRANSACTIONS

                  3.1 Flip-in. (a) In the event that prior to the Expiration
Time a Flip-in Date shall occur, except as provided in this Section 3.1, each
Right shall constitute the right to purchase from the Company, upon exercise
thereof in accordance with the terms hereof (but subject to Section 5.10), that
number of shares of Common Stock having an aggregate Market Price on the Stock
Acquisition Date equal to twice the Exercise Price for an amount in cash equal
to the Exercise Price (such right to be appropriately adjusted in order to
protect the interests of the holders of Rights generally in the event that on or
after such Stock Acquisition Date an event of a type analogous to any of the
events described in Section 2.4(a) or (b) shall have occurred with respect to
the Common Stock).

                  (b) Notwithstanding the foregoing, any Rights that are or were
Beneficially Owned, on or after the Stock Acquisition Date on which an Acquiring
Person became such, by such Acquiring Person or by an Affiliate or Associate


                                      -17-
<PAGE>   21
thereof or by any transferee, direct or indirect, of any of the foregoing shall
become void and any holder of such Rights (including transferees) shall
thereafter have no right to exercise or transfer such Rights under any provision
of this Agreement. If any Rights Certificate is presented for assignment or
exercise and the Person presenting the same will not complete the certification
set forth at the end of the form of assignment or notice of election to exercise
and provide such additional evidence of the identity of the Beneficial Owner and
its Affiliates and Associates (or former Beneficial Owners and their Affiliates
and Associates) as the Company shall reasonably request, then the Company shall
be entitled conclusively to deem the Beneficial Owner thereof to be an Acquiring
Person or an Affiliate or Associate thereof or a transferee of any of the
foregoing and accordingly will deem the Rights evidenced thereby to be void and
not transferable or exercisable.

                  (c) The Board of Directors of the Company may, at its option,
at any time after a Flip-in Date, to the fullest extent that applicable law
would not prohibit Rights owned by certain Persons referred to in Section 3.1(b)
becoming void pursuant to the provisions thereof, elect to exchange all (but not
less than all) the then outstanding Rights (which shall not include Rights that
have become void pursuant to the provisions of Section 3.1(b)) for shares of
Common Stock at an exchange ratio of one share of Common Stock per Right,
appropriately adjusted in order to protect the interests of holders of Rights
generally in the event that after the Separation Time an event of a type
analogous to any of the events described in Section 2.4(a) or (b) shall have
occurred with respect to the Common Stock (such exchange ratio, as adjusted from
time to time, being hereinafter referred to as the "Exchange Ratio").

                  Immediately upon the action of the Board of Directors of the
Company electing to exchange the Rights, without any further action and without
any notice, the right to exercise the Rights will terminate and each Right
(other than Rights that have become void pursuant to Section 3.1(b)) will
thereafter represent only the right to receive a number of shares of Common
Stock equal to the Exchange Ratio. Promptly after the action of the Board of
Directors electing to exchange the Rights, the Company shall give notice thereof
(specifying the steps to be taken to receive shares of Common Stock in exchange
for Rights) to the Rights Agent and the holders of the Rights (other than Rights
that have become void pursuant to Section 3.1(b)) outstanding immediately prior
thereto by mailing such notice in accordance with Section 5.9.


                                      -18-
<PAGE>   22
                  Each Person in whose name any certificate for shares is issued
upon the exchange of Rights pursuant to this Section 3.1(c) or Section 3.1(d)
shall for all purposes be deemed to have become the holder of record of the
shares represented thereby on, and such certificate shall be dated, the date
upon which the Rights Certificate evidencing such Rights was duly surrendered
and payment of any applicable taxes and other governmental charges payable by
the holder was made; provided, however, that if the date of such surrender and
payment is a date upon which the stock transfer books of the Company are closed,
such Person shall be deemed to have become the record holder of such shares on,
and such certificate shall be dated, the next succeeding Business Day on which
the stock transfer books of the Company are open.

                  (d) Whenever the Company shall become obligated under Section 
3.1(a) or (c) to issue shares of Common Stock upon exercise of or in exchange
for Rights, the Company, at its option, may substitute therefor shares of
Participating Preferred Stock, at a ratio of one one-hundredth of a share of
Participating Preferred Stock for each share of Common Stock so issuable.

                  (e) In the event that there shall not be sufficient treasury
shares or authorized but unissued shares of Common Stock or Participating
Preferred Stock of the Company to permit the exercise or exchange in full of the
Rights in accordance with Section 3.1(a) or (c), and the Company elects not to,
or is otherwise unable to, make the exchange referred to in Section 3.1(c), the
Company shall take such action as shall be necessary to ensure and provide, to
the extent permitted by applicable law and any agreements or instruments in
effect on the Stock Acquisition Date to which it is a party, that each Right
shall thereafter constitute the right to receive, (x) at the Company's option,
either (A) in return for the Exercise Price, debt or equity securities or other
assets (or a combination thereof) having a fair value equal to twice the
Exercise Price, or (B) without payment of consideration (except as otherwise
required by applicable law), debt or equity securities or other assets (or a
combination thereof) having a fair value equal to the Exercise Price, or (y) if
the Board of Directors of the Company elects to exchange the Rights in
accordance with Section 3.1(c), debt or equity securities or other assets (or a
combination thereof) having a fair value equal to the product of the Market
Price of a share of Common Stock on the Flip-in Date times the Exchange Ratio in
effect on the Flip-in Date, where in any case set forth in (x) or (y) above the
fair value of such debt or equity securities or other assets shall be as
determined in good faith by the Board of Directors of the Company, after


                                      -19-

consultation with a nationally recognized investment banking firm.

                  3.2 Flip-over. (a) Prior to the Expiration Time, the Company
shall not enter into any agreement with an Acquiring Person with respect to,
consummate or permit to occur any Flip-over Transaction or Event unless and
until it shall have entered into a supplemental agreement with the Flip-over
Entity, for the benefit of the holders of the Rights, providing that, upon
consummation or occurrence of the Flip-over Transaction or Event (i) each Right
shall thereafter constitute the right to purchase from the Flip-over Entity,
upon exercise thereof in accordance with the terms hereof, that number of shares
of Flip-over Stock of the Flip-over Entity having an aggregate Market Price on
the date of consummation or occurrence of such Flip-over Transaction or Event
equal to twice the Exercise Price for an amount in cash equal to the Exercise
Price (such right to be appropriately adjusted in order to protect the interests
of the holders of Rights generally in the event that after such date of
consummation or occurrence an event of a type analogous to any of the events
described in Section 2.4(a) or (b) shall have occurred with respect to the
Flip-over Stock) and (ii) the Flip-over Entity shall thereafter be liable for,
and shall assume, by virtue of such Flip-over Transaction or Event and such
supplemental agreement, all the obligations and duties of the Company pursuant
to this Agreement. The provisions of this Section 3.2 shall apply to successive
Flip-over Transactions or Events.

                  (b) Prior to the Expiration Time, unless the Rights will be
redeemed pursuant to Section 5.1 hereof in connection therewith, the Company
shall not enter into any agreement with respect to, consummate or permit to
occur any Flip-over Transaction or Event if at the time thereof there are any
rights, warrants or securities outstanding or any other arrangements, agreements
or instruments which would eliminate or otherwise diminish in any material
respect the benefits intended to be afforded by this Rights Agreement to the
holders of Rights upon consummation of such transaction.

                                   ARTICLE IV

                                THE RIGHTS AGENT

                  4.1 General. (a) The Company hereby appoints the Rights Agent
to act as agent for the Company in accordance with the terms and conditions
hereof, and the Rights Agent hereby accepts such appointment. 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


                                      -20-
<PAGE>   24
counsel fees and other disbursements incurred in the administration and
execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability, or expense, incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted to be done by the Rights Agent in connection with the
acceptance and administration of this Agreement, including the costs and
expenses of defending against any claim of liability.

                  (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 Agreement in reliance upon any
certificate for securities purchasable upon exercise of Rights, Rights
Certificate, certificate 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.

                  4.2 Merger or Consolidation or Change of Name 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 is a party, or any corporation succeeding to the shareholder
services business of the Rights Agent or any successor Rights Agent, will be the
successor to the Rights Agent under this 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 4.4 hereof. In case at the time
such successor Rights Agent succeeds to the agency created by this Agreement any
of the Rights Certificates have been countersigned but not delivered, any such
successor Rights Agent may adopt the countersignature of the predecessor Rights
Agent and deliver such Rights Certificates so countersigned; and in case at that
time any of the Rights Certificates have not been countersigned, any successor
Rights Agent may countersign such Rights 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 Rights Certificates will have the full force provided in the
Rights Certificates and in this Agreement.

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

                  4.3 Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Rights Certificates,
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 opinion of such counsel will
         be full and complete authorization and protection to the Rights Agent
         as to any action taken or omitted by it in good faith and in accordance
         with such opinion.

                  (b) Whenever in the performance of its duties under this
         Agreement the Rights Agent deems it necessary or desirable that any
         fact or matter be proved or established by the Company prior to 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 a person believed by the Rights Agent to be the Chairman of
         the Board, the President, the Chief Executive Officer or any Vice
         Chairman and by the Treasurer or any Assistant Treasurer or the
         Secretary or any Assistant Secretary of the Company and delivered to
         the Rights Agent; and such certificate will be full authorization to
         the Rights Agent for any action taken or suffered in good faith by it
         under the provisions of this Agreement in reliance upon such
         certificate.

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

                  (d) The Rights Agent will not be liable for or by reason of
         any of the statements of fact or recitals contained in this Agreement
         or in the certificates for securities purchasable upon exercise of
         Rights or the Rights Certificates (except its countersignature


                                      -22-
<PAGE>   26
         thereof) or be required to verify the same, but all such statements and
         recitals are and will be deemed to have been made by the Company only.

                  (e) The Rights Agent will not be under any responsibility in
         respect of the validity of this Agreement or the execution and delivery
         hereof (except the due authorization, execution and delivery hereof by
         the Rights Agent) or in respect of the validity or execution of any
         certificate for securities purchasable upon exercise of Rights or
         Rights Certificates (except its countersignature thereof); nor will it
         be responsible for any breach by the Company of any covenant or
         condition contained in this Agreement or in any Rights Certificate; nor
         will it be responsible for any change in the exercisability of the
         Rights (including the Rights becoming void pursuant to Section 3.1(b)
         hereof) or any adjustment required under the provisions of Section 2.4,
         3.1 or 3.2 hereof 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 after receipt of the certificate contemplated by Section 2.4
         describing any such adjustment); nor will it by any act hereunder be
         deemed to make any representation or warranty as to the authorization
         or reservation of any securities purchasable upon exercise of Rights or
         any Rights or as to whether any securities purchasable upon exercise of
         Rights will, when issued, be duly and validly authorized, executed,
         issued and delivered and 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 Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
         accept instructions with respect to the performance of its duties
         hereunder from any person believed by the Rights Agent to be the
         Chairman of the Board, the President, Chief Executive Officer or any
         Vice Chairman or the Secretary or any Assistant Secretary or the
         Treasurer or any Assistant Treasurer of the Company, and to apply to
         such persons for advice or instructions in connection with its duties,
         and it shall not be liable for any action taken or suffered by


                                      -23-
<PAGE>   27
         it in good faith in accordance with instructions of any such person.

                  (h) The Rights Agent and any shareholder, director, officer or
         employee of the Rights Agent may buy, sell or deal in Common Stock,
         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 Rights Agent under this 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 will 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 resulting from any such act, default, neglect or
         misconduct, provided reasonable care was exercised in the selection and
         continued employment thereof.

                  4.4 Change of Rights Agent. The Rights Agent may resign and be
discharged from its duties under this Agreement upon 90 days' notice (or such
lesser notice as is acceptable to the Company) in writing mailed to the Company
and to each transfer agent of Common Stock by registered or certified mail, and
to the holders of the Rights in accordance with Section 5.9. The Company may
remove the Rights Agent upon 30 days' notice in writing, mailed to the Rights
Agent and to each transfer agent of the Common Stock by registered or certified
mail, and to the holders of the Rights in accordance with Section 5.9. If the
Rights Agent should resign or be removed or otherwise become incapable of
acting, the Company will appoint a successor to the Rights Agent. If the Company
fails to make such appointment within a period of 30 days after 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 any Rights (which
holder shall, with such notice, submit such holder's Rights Certificate for
inspection by the Company), then the holder of any Rights 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 the Commonwealth of Pennsylvania, in good standing, having its
principal office in the Commonwealth of


                                      -24-
<PAGE>   28
Pennsylvania, which is authorized under such laws to exercise the powers of the
Rights Agent contemplated by this Agreement 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. After appointment, the successor Rights Agent will 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 will file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Stock, and mail a notice thereof in writing to the holders of the
Rights. Failure to give any notice provided for in this Section 4.4, 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.

                                    ARTICLE V

                                  MISCELLANEOUS

                  5.1 Redemption. (a) The Board of Directors of the Company may,
at its option, at any time prior to the close of business on the Flip-In Date,
elect to redeem all (but not less than all) the then outstanding Rights at the
Redemption Price and the Company, at its option, may pay the Redemption Price
either in cash or shares of Common Stock or other securities of the Company
deemed by the Board of Directors, 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 electing to redeem the Rights (or, if the resolution of the Board of
Directors electing to redeem the Rights states that the redemption will not be
effective until the occurrence of a specified future time or event, upon the
occurrence of such future time or event), without any further action and without
any notice, the right to exercise the Rights will terminate and each Right will
thereafter represent only the right to receive the Redemption Price in cash or
securities, as determined by the Board of Directors. Promptly after the Rights
are redeemed, the Company shall give notice of such redemption to the Rights
Agent and the holders of the then outstanding Rights by mailing such notice in
accordance with Section 5.9.


                                      -25-
<PAGE>   29
                  5.2 Expiration. The Rights and this Agreement shall expire at
the Expiration Time and no Person shall have any rights pursuant to this
Agreement or any Right after the Expiration Time, except, if the Rights are
exchanged or redeemed, as provided in Section 3.1(c), 3.1(d), 3.1(e) or 5.1.

                  5.3 Issuance of New Rights Certificates. Notwithstanding any
of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the number or kind or class of shares of stock purchasable upon
exercise of Rights made in accordance with the provisions of this Agreement. In
addition, in connection with the issuance or sale of shares of Common Stock by
the Company following the Separation Time and prior to the Expiration Time
pursuant to the terms of securities convertible or redeemable into shares of
Common Stock or to options, in each case issued or granted prior to, and
outstanding at, the Separation Time, the Company shall issue to the holders of
such shares of Common Stock, Rights Certificates representing the appropriate
number of Rights in connection with the issuance or sale of such shares of
Common Stock; provided, however, in each case, (i) no such Rights Certificates
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 to the Person to whom such Rights
Certificates would be issued, (ii) no such Rights Certificates shall be issued
if, and to the extent that, appropriate adjustment shall have otherwise been
made in lieu of the issuance thereof, and (iii) the Company shall have no
obligation to distribute Rights Certificates to any Acquiring Person or
Affiliate or Associate of an Acquiring Person or any transferee of any of the
foregoing.

                  5.4 Supplements and Amendments. The Company and the Rights
Agent may from time to time supplement or amend this Agreement without the
approval of any holders of Rights (i) in any respect prior to the Flip-in Date,
(ii) to make any changes on or after the Flip-in Date that the Company may deem
necessary or desirable and which shall not materially adversely affect the
interests of the holders of Rights generally or (iii) in order to cure any
ambiguity or to correct or supplement any provision contained herein which may
be inconsistent with any other provisions herein or otherwise defective. The
Rights Agent will duly execute and deliver any supplement or amendment hereto
requested by the Company which satisfies the terms of the preceding sentence.


                                      -26-
<PAGE>   30
                  5.5 Fractional Shares. If the Company elects not to issue
certificates representing fractional shares upon exercise or redemption of
Rights, the Company shall, in lieu thereof, (a) evidence such fractional shares
by depositary receipts issued pursuant to an appropriate agreement between the
Company and a depositary selected by it, provided that such agreement shall
provide that each holder of a depositary receipt shall have all of the rights,
privileges and preferences to which he would be entitled as a beneficial owner
of such fractional share, or (b) pay to the registered holder of such Rights the
appropriate fraction of the Market Price per share in cash.

                  5.6 Rights of Action. Subject to the terms of this Agreement,
rights of action in respect of this Agreement, other than rights of action
vested solely in the Rights Agent, are vested in the respective holders of the
Rights; and any holder of any Rights, without the consent of the Rights Agent or
of the holder of any other Rights, may, on such holder's own behalf and for such
holder's own benefit and the benefit of other holders of Rights, enforce, and
may institute and maintain any suit, action or proceeding against the Company to
enforce, or otherwise act in respect of, such holder's right to exercise such
holder's Rights in the manner provided in such holder's Rights Certificate and
in this 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 Agreement
and will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of, the obligations of
any Person subject to this Agreement.

                  5.7 Holder of Rights Not Deemed a Shareholder. No holder, as
such, of any Rights shall be entitled to vote, receive dividends or be deemed
for any purpose the holder of shares or any other securities which may at any
time be issuable on the exercise of such Rights, nor shall anything contained
herein or in any Rights Certificate be construed to confer upon the holder of
any Rights, as such, any of the rights of a shareholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
shareholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
shareholders (except as provided in Section 5.8 hereof), or to receive dividends
or subscription rights, or otherwise, until such Rights shall have been
exercised or exchanged in accordance with the provisions hereof.

propose after the Separation Time and prior to the Expiration Time (i) to effect

any Flip-in Date or Flip-over Transaction or Event or (ii) to effect the
liquidation, dissolution or winding up of the Company, then, in each such case,

hereof, a notice of such proposed action, which shall specify the Flip-in Date

action.

Company may suspend the exercisability of the Rights for a reasonable period of

                  In compliance with the requirements of Section 1522 of the
Pennsylvania Business Corporation Law, the undersigned corporation, desiring to
state the voting rights, designations, preferences, qualifications, privileges,
limitations, conversion rights and other special rights of a series of shares of
its Preferred Stock, hereby certifies that:

                  1. The name of the Corporation is Mellon Bank Corporation.

                  2. The resolution establishing and designating the series of
shares of Preferred Stock and fixing and determining the relative rights and
preferences of such series, as adopted at a meeting duly convened and held on
October 15, 1996, set forth in full, is as follows:

                  RESOLVED, that pursuant to the authority vested in the Board
of Directors of this Corporation by the Restated Articles of Incorporation, as
amended, there is hereby created and the Corporation be, and it hereby is,
authorized to issue up to 2,000,000 shares of a new series of Preferred Stock
and hereby fixes the designations, powers, preferences and relative,
participating, optional or other special rights, and the qualifications,
limitations or restrictions as follows:

                                  (i) The distinctive serial designation of this
                  series shall be "Participating Preferred Stock" (hereinafter
                  called "this Series"). Each share of this Series shall be
                  identical in all respects with the other shares of this Series
                  except as to the dates from and after which dividends thereon
                  shall be cumulative.

                                 (ii) The number of shares in this Series shall
                  initially be _______, which number may from time to time be
                  increased or decreased (but not below the number then
                  outstanding) by the Board of Directors. Shares of this Series
                  purchased by the
<PAGE>   43
                  Corporation shall be cancelled and shall revert to authorized
                  but unissued shares of Preferred Stock undesignated as to
                  series. Shares of this Series may be issued in fractional
                  shares, which fractional shares shall entitle the holder, in
                  proportion to such holder's fractional share, to all rights of
                  a holder of a whole share of this Series.

                                 (iii) The holders of full or fractional shares
                  of this Series shall be entitled to receive, when and as
                  declared by the Board of Directors, but only out of funds
                  legally available therefor, dividends, (A) on each date that
                  dividends or other distributions (other than dividends or
                  distributions payable in Common Stock of the Corporation) are
                  payable on or in respect of Common Stock comprising part of
                  the Reference Package (as defined below), in an amount per
                  whole share of this Series equal to the aggregate amount of
                  dividends or other distributions (other than dividends or
                  distributions payable in Common Stock of the Corporation) that
                  would be payable on such date to a holder of the Reference
                  Package and (B) on the last day of March, June, September and
                  December in each year, in an amount per whole share of this
                  Series equal to the excess (if any) of $________* over the
                  aggregate dividends paid per whole share of this Series during
                  the three month period ending on such last day. Each such
                  dividend shall be paid to the holders of record of shares of
                  this Series on the date, not exceeding fifty days preceding
                  such dividend or distribution payment date, fixed for the
                  purpose by the Board of Directors in advance of payment of
                  each particular dividend or distribution. Dividends on each
                  full and each fractional share of this Series shall be
                  cumulative from the date such full or fractional share is
                  originally issued; provided that any such full or fractional
                  share originally issued after a dividend record date and on or
                  prior to the dividend payment date to which such record date
                  relates shall not be entitled to receive the dividend payable
                  on such dividend payment date or any amount in respect of the
                  period from such original issuance to such dividend payment
                  date.

*   Insert an amount equal to 1/4 of 1% of the Exercise Price divided by the
    number of shares purchasable upon exercise of one Right (i.e., a guaranteed
    1% dividend).

                           The term "Reference Package" shall initially mean 100
                  shares of Common Stock, par value $.50 per share ("Common
                  Stock"), of the Corporation. In the event the Corporation
                  shall, at any time after the close of business on
                  _____________,* (A) declare or pay a dividend on any Common
                  Stock payable in Common Stock, (B) subdivide any Common Stock
                  or (C) combine any Common Stock into a smaller number of
                  shares, then and in each such case the Reference Package after
                  such event shall be the Common Stock that a holder of the
                  Reference Package immediately prior to such event would hold
                  thereafter as a result thereof.

                           Holders of shares of this Series shall not be
                  entitled to any dividends, whether payable in cash, property
                  or stock, in excess of full cumulative dividends, as herein
                  provided on this Series.

                           So long as any shares of this Series are outstanding,
                  no dividend (other than a dividend in Common Stock or in any
                  other stock ranking junior to this Series as to dividends and
                  upon liquidation) shall be declared or paid or set aside for
                  payment or other distribution declared or made upon the Common
                  Stock or upon any other stock ranking junior to this Series as
                  to dividends or upon liquidation, nor shall any Common Stock
                  nor any other stock of the Corporation ranking junior to or on
                  a parity with this Series as to dividends or upon liquidation
                  be redeemed, purchased or otherwise acquired for any
                  consideration (or any moneys be paid to or made available for
                  a sinking fund for the redemption of any shares of any such
                  stock) by the Corporation (except by conversion into or
                  exchange for stock of the Corporation ranking junior to this
                  Series as to dividends and upon liquidation), unless, in each
                  case, the full cumulative dividends (including the dividend to
                  be due upon payment of such dividend, distribution,
                  redemption, purchase or other acquisition) on all outstanding
                  shares of this Series shall have been, or shall
                  contemporaneously be, paid.

                           The preferences of each share of this Series with
                  respect to dividend payments or distributions upon the
                  voluntary or involuntary liquidation, dissolution or winding

                  (herein referred to as "liquidation"), as the case may be,
                  will be in every respect on a parity with the preferences of
                  every other share of this Series as to dividend payments or
                  upon liquidation and of every other share of the Series I
                  Preferred Stock, Series J Preferred Stock, Series K Preferred
                  Stock, and of every other share of capital stock of the
                  Corporation which is not specifically made senior or junior to
                  the shares of this Series as to dividend payments or upon
                  liquidation. The rights of this Series will be senior to the
                  Common Stock of the Corporation with respect to dividend
                  payments and distribution upon liquidation of the Corporation.

                                 (iv) In the event of any merger, consolidation,
                  reclassification or other transaction in which the shares of
                  Common Stock are exchanged for or changed into other stock or
                  securities, cash and/or any other property, then in any such
                  case the shares of this Series shall at the same time be
                  similarly exchanged or changed in an amount per whole share
                  equal to the aggregate amount of stock, securities, cash
                  and/or any other property (payable in kind), as the case may
                  be, that a holder of the Reference Package would be entitled
                  to receive as a result of such transaction.

                                  (v) In the event of any liquidation,
                  dissolution or winding up of the affairs of the Corporation,
                  whether voluntary or involuntary, the holders of full and
                  fractional shares of this Series shall be entitled, before any
                  distribution or payment is made on any date to the holders of
                  the Common Stock or any other stock of the Corporation ranking
                  Junior to this Series upon liquidation, to be paid in full an
                  amount per whole share of this Series equal to the greater of
                  (A) $__________* or (B) the aggregate amount distributed or to
                  be distributed prior to such date in connection with such
