Debentures, Series A (the "Series A Subordinated Debentures"), to be issued by
the Corporation. The Series A Subordinated Debentures will mature on March 31,
2027, which date may be (i) shortened to a date not earlier than December   ,
2001 or (ii) extended to a date not later than March 31, 2046, in either case
if certain conditions are met (including, in the case of a shortening of the
Stated Maturity (as defined herein), the Corporation having received prior
approval of the Board of Governors of the Federal Reserve System (the "Federal
Reserve") to do so if then required under applicable capital guidelines or
policies). The Series A Preferred Securities will have a preference under
certain circumstances with respect to cash distributions and amounts payable
on liquidation or redemption over the Series A Common Securities. See
"Description of Preferred Securities--Subordination of Common Securities" in
the accompanying Prospectus.     
   
  Holders of the Series A Preferred Securities will be entitled to receive
preferential cumulative cash distributions accruing from the date of original
issuance and payable quarterly in arrears on the last day of March, June,
September and December of each year, commencing March 31, 1997, at the annual
rate of   % of the Liquidation Amount (as defined in the accompanying
Prospectus) of $25 per Series A Preferred Securities ("Distributions").
Subject to certain exceptions, as described herein, the Corporation has the
right to defer payment of interest on the Series A Subordinated Debentures at
any time or from time to time for a period not exceeding 20 consecutive
quarters with respect to each deferral period (each, an "Extension Period"),
provided that no Extension Period may extend beyond the Stated Maturity of the
Series A Subordinated Debentures. Upon the termination of any such Extension
Period and the payment of all interest then accrued and unpaid (together with
interest thereon at the rate of   %, compounded quarterly, to the extent
permitted by applicable law), the Corporation may elect to begin a new
Extension Period subject to the requirements set forth herein. If interest
payments on the Series A Subordinated Debentures are so deferred,
Distributions on the Series A Preferred Securities will also be deferred and
the Corporation will not be permitted, subject to certain exceptions described
herein, to declare or pay any cash distributions with respect to the
Corporation's capital stock or debt securities that rank pari passu with or
junior to the Series A Subordinated Debentures. During an Extension Period,
interest on the Series A Subordinated Debentures will continue to accrue (and
the amount of Distributions to which holders of the Series A Preferred
Securities are entitled will accumulate) at the rate of   % per annum,
compounded quarterly from the relevant payment date for such interest, and
holders of Series A Preferred Securities will be required to accrue interest
income for United States federal income tax purposes. See "Certain Terms of
Series A Subordinated Debentures--Option to Defer Interest Payments" and
"Certain Federal Income Tax Consequences--Interest Income and Original Issue
Discount."     
   
  The Series A Subordinated Debentures are unsecured and subordinated to all
Senior Debt (as defined in the accompanying Prospectus). At September 30,
1996, the aggregate amount of Senior Debt outstanding was approximately $2.689
billion. Because the Corporation is a holding company, the right of the
Corporation to participate in any distribution of assets of any subsidiary,
including Mellon Bank, N.A., The Dreyfus Corporation and The Boston Company,
Inc., upon such subsidiary's liquidation or reorganization or otherwise is
subject to the prior claims of creditors of that subsidiary except to the
extent that the Corporation may itself be recognized as a creditor of that
subsidiary. Accordingly, the Series A Subordinated Debentures (and therefore
the Series A Preferred Securities)     
 
                                      S-2

(cover page continued)
   
will be effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and holders thereof should only look to the assets
of the Corporation for payments on the Series A Subordinated Debentures. See
"Description of Subordinated Debentures--Subordination" in the accompanying
Prospectus.     
   
  The Corporation has, through the Series A Guarantee, the Trust Agreement,
the Series A Subordinated Debentures, the Indenture and the Expense Agreement
(each as defined herein), taken together, fully, irrevocably and
unconditionally guaranteed all of the Series A Issuer's obligations under the
Series A Preferred Securities. See "Relationship Among the Preferred
Securities, the Corresponding Junior Subordinated Debentures, the Expense
Agreement and the Guarantees--Full and Unconditional Guarantee" in the
accompanying Prospectus. The Series A Guarantee of the Corporation guarantees
the payment of Distributions and payments on liquidation or redemption of the
Series A Preferred Securities, but only in each case to the extent of funds
held by the Series A Issuer, as described herein (the "Series A Guarantee").
See "Description of Guarantees" in the accompanying Prospectus. If the
Corporation does not make interest payments on the Series A Subordinated
Debentures held by the Series A Issuer, the Series A Issuer will have
insufficient funds to pay Distributions on the Series A Preferred Securities.
The Series A Guarantee does not cover payment of Distributions when the Series
A Issuer has insufficient funds to pay such Distributions. In such event, a
holder of Series A Preferred Securities may institute a legal proceeding
directly against the Corporation pursuant to the terms of the Indenture to
enforce payment of amounts equal to such Distributions to such holder. See
"Description of Junior Subordinated Debentures--Enforcement of Certain Rights
By Holders of Preferred Securities" in the accompanying Prospectus. The
obligations of the Corporation under the Series A Guarantee and the Series A
Preferred Securities are subordinate and junior in right of payment to all
Senior Debt of the Corporation.     
   
  The Series A Preferred Securities are subject to mandatory redemption, in
whole or in part, upon repayment of Series A Subordinated Debentures at
maturity or their earlier redemption. Subject to the Corporation having
received prior approval of the Federal Reserve to do so if then required under
applicable capital guidelines or policies, the Series A Subordinated
Debentures are redeemable prior to maturity at the option of the Corporation
(i) on or after December   , 2001, in whole at any time or in part from time
to time, or (ii) at any time, in whole (but not in part), upon the occurrence
and continuation of a Tax Event or a Capital Treatment Event (each as defined
herein). In any case the redemption price for the Series A Preferred
Securities will be in the Aggregate Liquidation Amount of such Series A
Preferred Securities plus accumulated and unpaid Distributions thereon to the
date of redemption. See "Certain Terms of the Series A Preferred Securities--
Redemption."     
   
  The Corporation will have the right at any time to terminate the Series A
Issuer, subject to the Corporation having received prior approval of the
Federal Reserve to do so if then required under applicable capital guidelines
or policies. See "Certain Terms of Series A Preferred Securities--Liquidation
of Series A Issuer and Distribution of Series A Subordinated Debentures to
Holders." In the event of the termination of the Series A Issuer, after
satisfaction of liabilities to creditors of the Series A Issuer as required by
applicable law, the holders of the Series A Preferred Securities will be
entitled to receive a Liquidation Amount of $25 per Series A Preferred
Securities plus accumulated and unpaid Distributions thereon to the date of
payment, which may be in the form of a distribution of such amount in Series A
Subordinated Debentures in exchange therefor, subject to certain exceptions.
See "Description of Preferred Securities--Liquidation Distribution Upon
Termination" in the accompanying Prospectus.     
          
  Application will be made to list the Series A Preferred Securities on the
New York Stock Exchange under the symbol "     Pr". If Series A Subordinated
Debentures are distributed to the holders o     f Series A Preferred

Corporation will use its best efforts to list the Series A Subordinated
Debentures on the New York Stock Exchange or such other stock exchanges or

Securities are then listed or traded.
   
  The Series A Preferred Securities will be represented by global certificates
registered in the name of The Depository Trust Company ("DTC") or its nominee.
Beneficial interests in the Series A Preferred Securities will be shown on,
and transfers thereof will be effected only through, records maintained by
participants in DTC. Except as described in the accompanying Prospectus,
Series A Preferred Securities in certificated form will not be issued in
exchange for the global certificates. See "Certain Terms of Series A Preferred

Chase Manhattan Bank, as trustee (the "Debenture Trustee"), and (ii) the
"Trust Agreement" means the Amended and Restated Trust Agreement relating to
the Series A Issuer among the Corporation, as Depositor, The Chase Manhattan
Bank, as Property Trustee (the "Property Trustee"), Chase Manhattan Bank
Delaware, as Delaware Trustee (the "Delaware Trustee"), and the Administrative
Trustees named therein (collectively, with the Property Trustee and Delaware
Trustee, the "Issuer Trustees"). Each of the other capitalized terms used in
this Prospectus Supplement and not otherwise defined in this Prospectus
Supplement has the meaning set forth in the accompanying Prospectus.     
 
                                 RISK FACTORS
   
  Prospective purchasers of the Series A Preferred Securities should carefully
review the information contained elsewhere in this Prospectus Supplement and
in the accompanying Prospectus and should particularly consider the following
matters. In addition, because holders of Series A Preferred Securities may
receive Series A Subordinated Debentures in exchange therefor upon liquidation
of the Series A Issuer, prospective purchasers of Series A Preferred
Securities are also making an investment decision with regard to the Series A
Subordinated Debentures and should carefully review all the information
regarding the Series A Subordinated Debentures contained herein.     
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE SERIES A GUARANTEE AND THE
SERIES A SUBORDINATED DEBENTURES
   
  The obligations of the Corporation under the Series A Guarantee issued by
the Corporation for the benefit of the holders of Series A Securities and
under the Series A Subordinated Debentures are unsecured and rank subordinate
and junior in right of payment to all Senior Debt of the Corporation. At
September 30, 1996, the aggregate amount of Senior Debt of the Corporation
outstanding was approximately $2.689 billion. Because the Corporation is a
holding company, the right of the Corporation to participate in any
distribution of the assets of any subsidiary, including Mellon Bank, N.A., The
Dreyfus Corporation and The Boston Company, Inc., upon such subsidiary's
liquidation or reorganization or otherwise, is subject to the prior claims of
creditors of that subsidiary, except to the extent that the Corporation may
itself be recognized as a creditor of that subsidiary. Accordingly, the Series
A Subordinated Debentures will be effectively subordinated to all existing and
future liabilities of the Corporation's subsidiaries, and holders of Series A
Subordinated Debentures should look only to the assets of the Corporation for
payments on the Series A Subordinated Debentures. See "the Corporation." None
of the Indenture, the Series A Guarantee, the Trust Agreement or the Expense
Agreement places any limitation on the amount of secured or unsecured debt,
including Senior Debt, that may be incurred by the Corporation. See
"Description of Guarantees--Status of the Guarantees" and "Description of
Junior Subordinated Debentures--Subordination" in the accompanying Prospectus.
    
  The ability of the Series A Issuer to pay amounts due on the Series A
Preferred Securities is solely dependent upon the Corporation making payments
on the Series A Subordinated Debentures as and when required.
   
OPTION TO DEFER INTEREST PAYMENT; TAX CONSEQUENCES; MARKET PRICE CONSEQUENCES
       
  So long as no event of default under the Indenture has occurred or is
continuing, the Corporation has the right under the Indenture to defer payment
of interest on the Series A Subordinated Debentures at any time or from time
to time for a period not exceeding 20 consecutive quarters with     
 
                                      S-5
<PAGE>
 
   
respect to each Extension Period, provided that no Extension Period may extend
beyond the Stated Maturity of the Series A Subordinated Debentures. As a
consequence of any such deferral, quarterly Distributions on the Series A
Preferred Securities by the Series A Issuer will also be deferred (and the
amount of Distributions to which holders of the Series A Preferred Securities
are entitled will accumulate additional Distributions thereon at the rate of
  % per annum, compounded quarterly from the relevant payment date for such
Distributions) during any such Extension Period. During any such Extension
Period, the Corporation may not, and may not permit any subsidiary of the
Corporation to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any
of the Corporation's capital stock, or (ii) make any payment of principal,
interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Corporation (including other Series of Junior Subordinated
Debentures) that rank pari passu with or junior in interest to the Series A
Subordinated Debentures or (iii) make any guarantee payments with respect to
any guarantee by the Corporation of the debt securities of any subsidiary of
the Corporation if such guarantee ranks pari passu with or junior in interest
to the Series A Subordinated Debentures (other than (a) dividends or
distributions in capital stock of the Corporation, (b) any declaration of a
dividend in connection with the implementation of a stockholders' rights plan,
or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under the Series A Guarantee and (d) purchases of common stock
related to the issuance of common stock or rights under any of the
Corporation's benefit plans for its directors, officers or employees, related
to the issuance of common stock or rights under a dividend reinvestment and
stock purchase plan, or related to the issuance of common stock (or securities
convertible into or exchangeable for common stock) as consideration in an
acquisition transaction). Prior to the termination of any such Extension
Period, the Corporation may further defer the payment of interest, provided
that no Extension Period may exceed 20 consecutive quarters or extend beyond
the Stated Maturity of the Series A Subordinated Debentures. Upon the
termination of any Extension Period and the payment of all interest then
accrued and unpaid (together with interest thereon at the annual rate of   %,
compounded quarterly from the interest payment date for such interest, to the
extent permitted by applicable law), the Corporation may elect to begin a new
Extension Period subject to the above requirements. There is no limitation on
the number of times that the Corporation may elect to begin an Extension
Period. See "Certain Terms of Series A Preferred Securities--Distributions"
and "Certain Terms of Series A Subordinated Debentures--Option to Defer
Interest Payments."     
   
  Should an Extension Period occur, a holder of Series A Preferred Securities
will be required to accrue income (in the form of original issue discount) in
respect of its pro rata share of the Series A Subordinated Debentures held by
the Series A Issuer for United States federal income tax purposes. As a
result, a holder of Series A Preferred Securities will be required to include
such income in gross income for United States federal income tax purposes in
advance of the receipt of cash attributable to such income, and will not
receive the cash related to such income from the Series A Issuer if the holder
disposes of the Series A Preferred Securities prior to the record date for the
payment of Distributions. See "Certain Federal Income Tax Consequences--
Interest Income and Original Issue Discount" and "--Sale or Redemption of
Series A Preferred Securities."     
   
  The Corporation has no current intention of exercising its right to defer
payments of interest on the Series A Subordinated Debentures. However, should
the Corporation elect to exercise such right in the future, the market price
of the Series A Preferred Securities is likely to be affected. A holder that
disposes of its Series A Preferred Securities during an Extension Period,
therefore, might not receive the same return on its investment as a holder
that continues to hold its Series A Preferred Securities.     
   
TAX EVENT OR CAPITAL TREATMENT EVENT--REDEMPTION     
   
  Upon the occurrence and continuation of a Tax Event or Capital Treatment
Event, (whether occurring before or after December   , 2001) the Corporation
has the right to redeem the Series A     
 
                                      S-6
<PAGE>
 
   
Subordinated Debentures in whole (but not in part) prior to December   , 2001
and within 90 days following the occurrence of such Tax Event or Capital
Treatment Event and thereby cause a mandatory redemption of the Series A
Preferred Securities before, as well as after, December   , 2001. The exercise
of such right is subject to the Corporation having received prior approval of
the Federal Reserve to do so if then required under applicable guidelines or
policies.     
   
  A "Tax Event" means the receipt by the Series A Issuer of an opinion of
counsel experienced in such matters to the effect that, as a result of any
amendment to, or change (including any announced proposed change) in, the laws
(or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
such proposed change, pronouncement or decision is announced on or after the
date of issuance of the Series A Preferred Securities under the Trust
Agreement, there is more than an insubstantial risk that (i) the Series A
Issuer is, or will be within 90 days of the date of such opinion, subject to
United States federal income tax with respect to income received or accrued on
the Series A Subordinated Debentures, (ii) interest payable by the Corporation
on the Series A Subordinated Debentures is not, or within 90 days of the date
of such opinion, will not be, deductible by the Corporation, in whole or in
part, for United States federal income tax purposes or (iii) the Series A
Issuer is, or will be within 90 days of the date of the opinion, subject to
more than a de minimis amount of other taxes, duties or other governmental
charges.     
   
  A "Capital Treatment Event" means the reasonable determination by the
Corporation that, as a result of any amendment to, or change (including any
proposed change) in, the laws (or any regulations thereunder) of the United
States or any political subdivision thereof or therein, or as a result of any
official or administrative pronouncement or action or judicial decision
interpreting or applying such laws or regulations, which amendment or change
is effective or which proposed change, pronouncement, action or decision is
announced on or after the date of issuance of the Series A Preferred
Securities under the Trust Agreement, there is more than an insubstantial risk
that the Corporation will not be entitled to treat an amount equal to the
Liquidation Amount of the Series A Preferred Securities as "Tier I Capital"
(or the then equivalent thereof) for purposes of the capital adequacy
guidelines of the Federal Reserve, as then in effect and applicable to the
Corporation.     
   
  See "Risk Factors--Possible Tax Law Changes Affecting the Series A Preferred
Securities" for a discussion of certain legislative proposals that, if
adopted, could give rise to a Tax Event, which may permit the Corporation to
cause a redemption of the Series A Preferred Securities prior to December   ,
2001.     
 
EXCHANGE OF SERIES A PREFERRED SECURITIES FOR SERIES A SUBORDINATED DEBENTURES
   
  The Corporation will have the right at any time to terminate the Series A
Issuer and after satisfaction of liabilities to creditors of the Series A
Issuer as required by applicable law cause the Series A Subordinated
Debentures to be distributed to the holders of the Series A Preferred
Securities in exchange therefor upon liquidation of the Series A Issuer. The
exercise of such right is subject to the Corporation having received prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies. See "Certain Terms of Series A Preferred Securities--
Liquidation of Series A Issuer and Distribution of Series A Subordinated
Debentures to Holders."     
   
  Under current United States federal income tax law and interpretations, a
distribution of the Series A Subordinated Debentures upon a liquidation of the
Series A Issuer should not be a taxable event to holders of the Series A
Preferred Securities. However, if a Tax Event were to occur which would cause
the Series A Issuer to be subject to United States federal income tax with
respect to income received     
 
                                      S-7
<PAGE>
 
   
or accrued on the Series A Subordinated Debentures, a distribution of the
Series A Subordinated Debentures by the Series A Issuer could be a taxable
event to the Series A Issuer and the holders of the Series A Preferred
Securities. See "Certain Federal Income Tax Consequences--Distribution of the
Series A Subordinated Debentures to Holders of Series A Preferred Securities."
    
SHORTENING OF STATED MATURITY OF SERIES A SUBORDINATED DEBENTURES
   
  The Corporation will have the right at any time to shorten the maturity of
the Series A Subordinated Debentures to a date not earlier than December   ,
2001 and thereby cause the Series A Preferred Securities to be redeemed on
such earlier date. The exercise of such right is subject to the Corporation
having received prior approval of the Federal Reserve if then required under
applicable capital guidelines or policies.     
 
EXTENSION OF STATED MATURITY OF SERIES A SUBORDINATED DEBENTURES
   
  The Corporation will also have the right to extend the maturity of the
Series A Subordinated Debentures whether or not the Series A Issuer is
liquidated and the Series A Subordinated Debentures are distributed to holders
of the Series A Preferred Securities to a date no later than the 49th
anniversary of the initial issuance of the Series A Preferred Securities,
provided that the Corporation can extend the maturity only if at the time such
election is made and at the time of such extension (i) the Corporation is not
in bankruptcy, otherwise insolvent or in liquidation, (ii) the Corporation is
not in default in the payment of any interest or principal on the Series A
Subordinated Debentures, (iii) if the Series A Issuer has not been liquidated,
the Series A Issuer is not in arrears on payments of Distributions on the
Series A Preferred Securities and no deferred Distributions are accumulated
and (iv) the Series A Subordinated Debentures are rated not less than BBB- by
Standard & Poor's Ratings Services or Baa3 by Moody's Investors Service, Inc.
or the equivalent by any other nationally recognized statistical rating
organization. To the extent that the Stated Maturity of the Series A
Subordinated Debentures is extended at such time as the Series A Preferred
Securities are outstanding, the Series A Preferred Securities would remain
outstanding until such extended date or until redeemed at an earlier date.
    
MARKET PRICES
   
  There can be no assurance as to the market prices for Series A Preferred
Securities or Series A Subordinated Debentures that may be distributed in
exchange for Series A Preferred Securities upon liquidation of the Series A
Issuer. Accordingly, the Series A Preferred Securities that an investor may
purchase, whether pursuant to the offer made hereby or in the secondary
market, or the Series A Subordinated Debentures that a holder of Series A
Preferred Securities may receive on liquidation of the Series A Issuer, may
trade at a discount to the price that the investor paid to purchase the Series
A Preferred Securities offered hereby. As a result of the existence of the
Corporation's right to defer interest payments, the market price of the Series
A Preferred Securities (which represent beneficial ownership interest in the
Series A Issuer) may be more volatile than the market prices of other debt
securities that are not subject to such optional deferrals. In addition,
because the Corporation has the right (i) to shorten the Stated Maturity of
the Series A Subordinated Debentures (subject to prior approval of the Federal
Reserve if then required under applicable capital guidelines or policies) or
(ii) to extend the maturity of the Series A Subordinated Debentures (subject
to the conditions described above), there can be no assurance that the
Corporation will not exercise its option to change the maturity of the Series
A Subordinated Debentures as permitted by the terms thereof and of the
Indenture. See "Certain Terms of the Series A Subordinated Debentures" and
"Description of Junior Subordinated Debentures--Corresponding Junior
Subordinated Debentures" in the accompanying Prospectus.     
 
                                      S-8
<PAGE>
 
RIGHTS UNDER THE SERIES A GUARANTEE
   
  The Series A Guarantee guarantees to the holders of the Series A Securities
the following payments, to the extent not paid by the Series A Issuer: (i) any
accumulated and unpaid Distributions required to be paid on the Series A
Securities, to the extent that the Series A Issuer has funds on hand available
therefor at such time, (ii) the redemption price with respect to any Series A
Securities called for redemption, to the extent that the Series A Issuer has
funds on hand available therefor at such time, and (iii) upon a voluntary or
involuntary dissolution, winding up or liquidation of the Series A Issuer
(unless the Series A Subordinated Debentures are distributed to holders of the
Series A Securities), the lesser of (a) the aggregate of the Liquidation
Amount and all accumulated and unpaid Distributions to the date of payment to
the extent that the Series A Issuer has funds on hand available therefor at
such time, and (b) the amount of assets of the Series A Issuer remaining
available for distribution to holders of the Series A Securities after payment
of creditors of the Series A Issuer as required by applicable law. The Series
A Guarantee will be qualified as an indenture under the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"). The Chase Manhattan Bank will
act as the indenture trustee under the Series A Guarantee (the "Guarantee
Trustee") for the purpose of compliance with the Trust Indenture Act and will
hold the Series A Guarantee for the benefit of the holders of the Series A
Securities. The Chase Manhattan Bank will also act as Debenture Trustee for
the Series A Subordinated Debentures and as Property Trustee and Chase
Manhattan Bank Delaware will act as Delaware Trustee under the Trust
Agreement.     
   
  The holders of not less than a majority in aggregate Liquidation Amount of
the Series A Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Series A Guarantee or to direct the exercise of any trust power
conferred upon the Guarantee Trustee under the Series A Guarantee. Any holder
of the Series A Securities may institute a legal proceeding directly against
the Corporation to enforce its rights under the Series A Guarantee without
first instituting a legal proceeding against the Series A Issuer, the
Guarantee Trustee or any other person or entity. If the Corporation were to
default on its obligation to pay amounts payable under the Series A
Subordinated Debentures, the Series A Issuer would lack funds for the payment
of Distributions or amounts payable on redemption of the Series A Securities
or otherwise, and, in such event, holders of the Series A Securities would not
be able to rely upon the Series A Guarantee for payment of such amounts.
Instead, if an event of default under the Indenture shall have occurred and be
continuing and such event is attributable to the failure of the Corporation to
pay interest on or principal of the Series A Subordinated Debentures on the
applicable payment date, then a holder of Series A Securities may institute a
legal proceeding directly against the Corporation pursuant to the terms of the
Indenture for enforcement of payment to such holder of the principal of or
interest on such Series A Subordinated Debentures having a principal amount
equal to the aggregate Liquidation Amount of the Series A Securities of such
holder (a "Direct Action"). In connection with such Direct Action, the
Corporation will have a right of set-off under the Indenture to the extent of
any payment made by the Corporation to such holder of Series A Securities in
the Direct Action. Except as described herein, holders of Series A Securities
will not be able to exercise directly any other remedy available to the
holders of the Series A Subordinated Debentures or assert directly any other
rights in respect of the Series A Subordinated Debentures. See "Description of
Junior Subordinated Debentures--Enforcement of Certain Rights of Holders of
Preferred Securities," "Debenture Events of Default" and "Description of
Guarantees" in the accompanying Prospectus. The Trust Agreement provides that
each holder of Series A Securities by acceptance thereof agrees to the
provisions of the Series A Guarantee, the Expense Agreement and the Indenture.
    
LIMITED VOTING RIGHTS
   
  Holders of Series A Preferred Securities generally will have limited voting
rights relating only to the modification of the Series A Preferred Securities
and the exercise of the Series A Issuer's rights     
 
                                      S-9
<PAGE>
 
   
as holder of Series A Subordinated Debentures and the Series A Guarantee.
Holders of Series A Preferred Securities will not be entitled to vote to
appoint, remove or replace the Property Trustee, or the Delaware Trustee or
any Administrative Trustee, and such voting rights are vested exclusively in
the holder of the Series A Common Securities except, with respect to the
Property Trustee and the Delaware Trustee, upon the occurrence of certain
events described in the accompanying Prospectus. The Property Trustee, the
Administrative Trustees and the Corporation may amend the Trust Agreement
without the consent of holders of Series A Preferred Securities to ensure that
the Series A Issuer will be classified for United States federal income tax
purposes as a grantor trust unless such action materially and adversely
affects the interests of such holders. See "Description of Preferred
Securities--Voting Rights; Amendment of Each Trust Agreement" and "--Removal
of Issuer Trustees" in the accompanying Prospectus.     
 
TRADING CHARACTERISTICS OF SERIES A PREFERRED SECURITIES
   
  Application will be made to list the Series A Preferred Securities on the
New York Stock Exchange. The Series A Preferred Securities may trade at prices
that do not fully reflect the value of accrued and unpaid interest with
respect to the underlying Series A Subordinated Debenture. See "Certain
Federal Income Tax Consequences--Interest Income and Original Issue Discount"
and "Sale or Redemption of Series A Preferred Securities" for a discussion of
the United States federal income tax consequences that may result from a
taxable disposition of the Series A Securities.     
   
  As indicated above, application will be made to list the Series A Preferred
Securities on the New York Stock Exchange. If the Series A Preferred
Securities are not listed on a national securities exchange or the NASDAQ
National Market and the underwriters do not make a market for the securities,
the liquidity of the Series A Preferred Securities could be adversely
affected.     
 
POSSIBLE TAX LAW CHANGES AFFECTING THE SERIES A PREFERRED SECURITIES
   
  On March 19, 1996, the Revenue Reconciliation Bill of 1996 (the "Bill") was
released which would have, among other things, generally denied interest
deductions for interest on an instrument issued by a corporation that has a
maximum weighted average maturity of more than 40 years. The Bill would also
have generally denied interest deductions for interest on an instrument issued
by a corporation that has a maximum term of more than 20 years and that is not
shown as indebtedness on the separate balance sheet of the issuer or, where
the instrument is issued to a related party (other than a corporation), where
the holder or some other related party issues a related instrument that is not
shown as indebtedness on the issuer's consolidated balance sheet. For purposes
of determining the weighted average maturity or the term of an instrument, any
right to extend would be treated as exercised. The above-described provisions
of the Bill were proposed to be effective generally for instruments issued on
or after December 7, 1995. If either provision were to apply to the Series A
Subordinated Debentures, the Corporation would not be able to deduct interest
on the Series A Subordinated Debentures. However, on March 29, 1996, the
Chairmen of the Senate Finance and House Ways and Means Committees issued a
joint statement (the "Joint Statement") to the effect that it was their
intention that the effective date of the President's legislative proposals, if
adopted, would be no earlier than the date of appropriate Congressional
action. In addition, subsequent to the publication of the Joint Statement,
Senator Daniel Patrick Moynihan and Representatives Sam M. Gibbons and Charles
B. Rangel wrote letters to Treasury Department officials concurring with the
view expressed in the Joint Statement (the "Democrat Letters"). If the
principles contained in the Joint Statement and the Democrat Letters were
enacted, such legislation would not apply to the Series A Subordinated
Debentures. Under current law, the Corporation will be able to deduct interest
on the Series A Subordinated Debentures. There can be no assurance, however,
that current or future legislative proposals or final legislation will not
adversely affect the ability of the Corporation to deduct interest on the
Series A Subordinated Debentures. Such a change could give rise to a Tax
Event,     
 
                                     S-10
<PAGE>
 
   
which would permit the Corporation, upon approval of the Federal Reserve if
then required under applicable capital guidelines or policies of the Federal
Reserve, to cause a redemption of the Series A Preferred Securities before
December   , 2001. See "Certain Terms of Series A Subordinated Debentures--
Redemption" in this Prospectus Supplement and "Description of Preferred
Securities--Redemption or Exchange--Tax Event Redemption" in the accompanying
Prospectus. See also "Certain Federal Income Tax Consequences--Possible Tax
Law Changes."     
 
                               MELLON CAPITAL I
   
  Mellon Capital (the "Series A Issuer") is a statutory business trust created
under Delaware law pursuant to (i) the Trust Agreement executed by the
Corporation, as Depositor, The Chase Manhattan Bank, as Property Trustee,
Chase Manhattan Bank Delaware, as Delaware Trustee, and the Administrative
Trustees named therein, and (ii) the filing of a certificate of trust with the
Delaware Secretary of State on November 27, 1996. The Series A Issuer's
business and affairs are conducted by the Issuer Trustees: The Chase Manhattan
Bank, as Property Trustee, and Chase Manhattan Bank Delaware, as Delaware
Trustee, and two individual Administrative Trustees who are employees or
officers of or affiliated with the Corporation. The Series A Issuer exists for
the exclusive purposes of (i) issuing and selling the Series A Preferred
Securities and Series A Common Securities, (ii) using the proceeds from the
sale of such Securities to acquire Series A Subordinated Debentures issued by
the Corporation and (iii) engaging in only those other activities necessary,
or incidental thereto (such as registering the transfer of the Series A
Preferred Securities). Accordingly, the Series A Subordinated Debentures and
the right to reimbursement under the Expense Agreement will be the sole assets
of the Series A Issuer, and payments under the Series A Subordinated
Debentures and the Expense Agreement will be the sole revenue of the Series A
Issuer. All of the Series A Common Securities will be owned by the
Corporation. The Series A Common Securities will rank pari passu, and payments
will be made thereon pro rata, with the Series A Preferred Securities, except
that upon the occurrence and continuance of an event of default under the
Trust Agreement resulting from an event of default under the Indenture, the
rights of the Corporation as holder of the Series A Common Securities to
payment in respect of Distributions and payments upon liquidation, redemption
or otherwise will be subordinated to the rights of the holders of the Series A
Preferred Securities. See "Description of Preferred Securities--Subordination
of Common Securities" in the accompanying Prospectus. The Corporation will
acquire Series A Common Securities in an aggregate Liquidation Amount equal to
3% of the total capital of the Series A Issuer. The Series A Issuer has a term
of 55 years, but may terminate earlier as provided in the Trust Agreement. The
principal executive office of the Series A Issuer is c/o Mellon Bank
Corporation, One Mellon Bank Center, 500 Grant Street, Pittsburgh,
Pennsylvania 15258, Attention: Secretary, and its telephone number is (412)
234-5000. See "The Issuers" in the accompanying Prospectus.     
   
  It is anticipated that the Series A Issuer will not be subject to the
reporting requirements under the Securities Exchange Act of 1934, as amended
(the "Exchange Act").     
 
                            MELLON BANK CORPORATION
   
  Mellon Bank Corporation (the "Corporation") is a multibank holding company
incorporated under the laws of Pennsylvania in August 1971 and registered
under the Federal Bank Holding Company Act of 1956, as amended. The
Corporation provides a comprehensive range of financial products and services
in domestic and selected international markets. The Corporation's banking
subsidiaries are located in Pennsylvania, Massachusetts, Delaware, Maryland,
and New Jersey. Other subsidiaries are located in key business centers
throughout the United States and abroad. At September 30, 1996, the
Corporation was the 22nd largest bank holding company in the United States in
terms of assets.     
 
 
                                     S-11
<PAGE>
 
   
  The Corporation's principal direct subsidiaries are Mellon Bank, N.A.
("Mellon Bank"), The Boston Company, Inc. ("TBC"), Mellon Bank (DE) National
Association, Mellon Bank (MD) and a number of companies known as Mellon
Financial Services Corporations. The Corporation also owns a federal savings
bank headquartered in New Jersey, Mellon Bank, F.S.B. The Dreyfus Corporation
("Dreyfus"), one of the nation's largest mutual fund companies, is a wholly
owned subsidiary of Mellon Bank. The Corporation's banking subsidiaries engage
in retail financial services, commercial banking, trust and investment
management services, residential real estate loan financing, mortgage
servicing, mutual fund activities, equipment leasing and various securities-
related activities.     
   
  Mellon Bank, which has its executive offices in Pittsburgh, Pennsylvania,
became a subsidiary of the Corporation in November 1972. With its
predecessors, Mellon Bank has been in business since 1869. Mellon Bank is
comprised of six operating regions throughout Pennsylvania and in southern New
Jersey. Dreyfus, headquartered in New York, New York, serves primarily as an
investment adviser, manager and administrator of mutual funds. TBC, through
Boston Safe Deposit and Trust Company ("BSDT") and other subsidiaries, engages
in the business of institutional trust and custody, institutional asset
management, private asset management and banking services. TBC is
headquartered in Boston, Massachusetts. Mellon Bank (DE) National Association,
headquartered in Wilmington, Delaware, serves consumer and small to midsize
commercial markets throughout Delaware and provides nationwide cardholder
processing services. Mellon Bank (MD) is headquartered in Rockville, Maryland,
and serves consumer and small to midsize commercial markets throughout
Maryland. Mellon Bank (MD) has a Maryland state charter and is a member of the
Federal Reserve System. Mellon Bank, F.S.B., headquartered in Paramus, New
Jersey, provides corporate trust and personal trust services and serves
consumer and small to midsize commercial markets.     
   
  The Corporation's banking subsidiaries operate 1,104 domestic retail banking
locations, including 428 retail offices. The deposits of the national banking
subsidiaries, BSDT, Mellon Bank (MD) and Mellon Bank, F.S.B. are insured by
the Federal Deposit Insurance Corporation ("FDIC") to the extent provided by
law.     
 
  Other subsidiaries of the Corporation provide a broad range of bank-related
services, including equipment leasing, commercial loan financing, stock
transfer services, cash management and numerous trust and investment
management services. The types of financial products and services offered by
the Corporation's subsidiaries are subject to change.
 
  For analytical purposes, management has focused the Corporation into four
core business sectors: Consumer Investment Services, Consumer Banking
Services, Corporate/Institutional Investment Services and
Corporate/Institutional Banking Services. There is considerable
interrelationship among these sectors.
 
CONSUMER INVESTMENT SERVICES
 
  The Corporation provides a broad array of personal trust services,
investment services and retail mutual funds to consumers. These products and
services are offered principally through the private asset management trust
group of Mellon Bank and BSDT, through Dreyfus and throughout the

Note: The comparability of the information on the prior page has been affected
      by the Corporation's September 30, 1996 acquisition of the business
      equipment financing unit of USL Capital Corporation, the December 1993
      acquisition of AFCO Credit Corporation and CAFO, Inc., the May 1993
      acquisition of The Boston Company, the December 1992 acquisition of
      certain assets and deposit liabilities of Meritor Savings Bank and the
      December 1991 acquisition of United Penn Bank. These acquisitions, as
      well as other less material acquisitions and divestitures, are described
      in detail in the Corporation's Annual Reports on Form 10-K for the years
      ended December 31, 1991 through 1995, or other documents incorporated by
      reference herein.
(A) Results for 1994 exclude a $130 million after tax securities lending
    charge, $79 million after tax of Dreyfus merger-related expenses, $10
    million after tax of one-time losses on the disposition of securities
    available for sale previously owned by Dreyfus and $16 million of
    preferred stock dividends recorded in connection with the redemption of
    the Series H preferred stock. Results for 1993 exclude $112 million after
    tax of merger expenses and $53 million after tax of gains on the sale of
    securities related to the acquisition of The Boston Company. Results for
    periods prior to 1993 were calculated by applying a normalized effective
    tax rate of approximately 38% to pretax income. The unrecorded tax benefit
    that existed at the beginning of the periods prior to 1993 was included in
    the determination of the return on common shareholders' equity.
(B) Computed on a daily average basis.
(C) Calculated on a taxable equivalent basis, at tax rates approximating 35%
    for the nine months ended September 30, 1996 and 1995, and the full years
    ended 1995, 1994 and 1993 and 34% in all other years presented. Loan fees,
    nonaccrual loans and the related effect on income have been included in
    the calculation of the net interest margin.
(D) Period-end ratio.
(E) Segregated assets acquired in the 1992 Meritor acquisition are not
    reported as loans and therefore are not included in nonperforming loans.
    The reserve for segregated assets is not included in the reserve for
    credit losses. In December 1995, the Corporation segregated certain
    CornerStoneSM credit card loans, which had a history of delinquency, into
    an accelerated resolution portfolio, which is included in Other Assets on
    the balance sheet. Interest and principal receipts, fees and loan loss
    recoveries on loans in this portfolio are applied to reduce the carrying
    value of this portfolio.

(a) For purposes of computing these ratios, earnings represent consolidated
    income before income taxes plus consolidated fixed charges. Fixed charges,
    excluding interest on deposits, include interest expense (other than on
    deposits), one-third (the proportion deemed representative of the interest
    factor) of rental expense net of income from subleases, and amortization
    of debt issuance costs. Fixed charges, including interest on deposits,
    include all interest expense, one-third (the proportion deemed
    representative of the interest factor) of rental expense net of income
    from subleases, and amortization of debt issuance costs.
(b) Preferred stock dividend requirements for all years presented represent
    the pretax amount required to cover preferred stock dividends.

(a) The parent Corporation ratios include the accounts of the Corporation and
    Mellon Financial Company, a wholly owned subsidiary of the Corporation
    that functions as a financing entity for the Corporation and its
    subsidiaries by issuing commercial paper and other debt guaranteed by the
    Corporation. For purposes of computing these ratios, earnings represent
    parent Corporation income before taxes and equity in undistributed net
    income (loss) of subsidiaries, plus the fixed charges of the parent
    Corporation. Fixed charges represent interest expense, one-third (the
    proportion deemed representative of the interest factor) of rental expense
    net of income from subleases, and amortization of debt issuance costs.
    Because the ratio excludes from earnings the equity in undistributed net
    income (loss) of subsidiaries, the ratio varies with the payment of
    dividends by such subsidiaries.
(b) Preferred stock dividend requirements for all years presented represent
    the pretax amount required to cover preferred stock dividends.
 
                                USE OF PROCEEDS
   
  All of the proceeds from the sale of the Series A Preferred Securities will
be invested by the Series A Issuer in Series A Subordinated Debentures. The
Corporation intends that the proceeds from the sale of the Series A
Subordinated Debentures will be added to its general corporate funds and will
be used for general corporate purposes, including funding the redemption of
the Corporation's Series I Preferred Stock, which is currently scheduled for
December 16, 1996. The Corporation is required by the Federal Reserve to
maintain certain levels of capital for bank regulatory purposes. On October
21, 1996, the Federal Reserve announced that cumulative preferred securities
having the characteristics of the Series A Preferred Securities could be
included as Tier I capital for bank holding companies. Such Tier I capital
treatment, together with the Corporation's ability to deduct, for income tax
purposes, interest payable on the Series A Subordinated Debentures, will
provide the Corporation with a more cost-effective means of obtaining capital
for regulatory purposes than if the Corporation were to issue preferred stock.

                             ACCOUNTING TREATMENT
   
  For financial reporting purposes, the Series A Issuer will be treated as a
subsidiary of the Corporation and, accordingly, the accounts of the Series A
Issuer will be included in the consolidated financial statements of the
Corporation. The Series A Preferred Securities will be presented as a separate
line item in the consolidated balance sheets of the Corporation, under the
caption "Guaranteed Preferred Beneficial Interests in Corporation's Junior
Subordinated Deferrable Interest Debentures" and appropriate disclosures about
the Series A Preferred Securities, the Series A Guarantee and the Series A
Subordinated Debentures and the Expense Agreement will be included in the
notes to the consolidated financial statements. For financial reporting
purposes, the Corporation will record Distributions payable on the Series A
Preferred Securities as an expense in the consolidated statement of income.
       
  The Corporation has agreed that future financial reports of the Corporation
will: (i) present the Preferred Securities issued by other Issuer trusts on
the Corporation's balance sheet as a separate line term entitled "Guaranteed
Preferred Beneficial Interests in Corporation's Junior Subordinated Deferrable
Interest Debentures"; (ii) include in a footnote to the financial statements
disclosure that the sole assets of the trusts are the Junior Subordinated
Debentures (specifying as to each trust the principal amount, interest rate
and maturity date of Junior Subordinated Debentures held) and (iii) if Staff
Accounting Bulletin 53 treatment is sought then include, in an audited
footnote to the financial statements, disclose that (a) the trusts are wholly
owned, (b) the sole assets of the trusts are the Junior Subordinated
Debentures (specifying as to each trust the principal amount, interest rate
and maturity date of the Junior Subordinated Debentures held), and (c) the
obligations of the Corporation under the Junior Subordinated Debentures, the
Indenture, the relevant Trust Agreement, Expense Agreement, and the
Guarantees, in the aggregate, constitute a full and unconditional guarantee by
the Corporation of the trusts' obligations under the Preferred Securities
issued by each trust.     
 
                CERTAIN TERMS OF SERIES A PREFERRED SECURITIES
 
GENERAL
   
  The following summary of certain terms and provisions of the Series A
Preferred Securities supplements the description of the terms and provisions
of the Preferred Securities set forth in the accompanying Prospectus under the
heading "Description of Preferred Securities," to which description reference
is hereby made. This summary of certain terms and provisions of the Series A
Preferred Securities which describes the material provisions thereof, does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, the Trust Agreement to which reference is hereby made. The form
of the Trust Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus Supplement and accompanying Prospectus form
a part.     
 
DISTRIBUTIONS
   
  The Series A Preferred Securities represent beneficial ownership interests
in the Series A Issuer, and distributions on each Series A Preferred
Securities will be payable at the annual rate of   % of the stated Liquidation
Amount of $25, payable quarterly in arrears on March 31, June 30, September 30
and December 31 of each year, to the holders of the Series A Preferred
Securities on the relevant record dates. The record dates for the Series A
Preferred Securities will be, for so long as the Series A Preferred Securities
remain in book-entry form, one Business Day (as defined in the accompanying
Prospectus) prior to the relevant Distribution payment date and, in the event
the Series A Preferred Securities are not in book-entry form, the 15th day of
the month in which the relevant Distribution payment date occurs.
Distributions will accumulate from the date of original issuance. The first
Distribution payment date for the Series A Preferred Securities will be March
31, 1997. The amount of     
 
                                     S-19
<PAGE>
 
   
Distributions payable for any period will be computed on the basis of a 360-
day year of twelve 30-day months. In the event that any date on which
Distributions are payable on the Series A Preferred Securities is not a
Business Day, then payment of the Distributions payable on such date will be
made on the next succeeding day that is a Business Day (and without any
additional Distributions or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year,
such payment shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on the date such payment was
originally payable. See "Description of Preferred Securities--Distributions"
in the accompanying Prospectus.     
   
  So long as no event of default under the Indenture has occurred and is
continuing, the Corporation has the right under the Indenture to defer payment
of interest on the Series A Subordinated Debentures at any time or from time
to time for a period not exceeding 20 consecutive quarters with respect to
each Extension Period, provided that no Extension Period may extend beyond the
Stated Maturity of the Series A Subordinated Debentures. As a consequence of
any such deferral of interest payments by the Corporation, quarterly
Distributions on the Series A Preferred Securities by the Series A Issuer will
also be deferred during any such Extension Period. Distributions to which
holders of the Series A Preferred Securities are entitled will accumulate
additional Distributions thereon at the rate per annum of   % thereof,
compounded quarterly from the relevant payment date for such Distributions.
The term "Distributions" as used herein shall include any such additional
Distributions. During any such Extension Period, the Corporation may not, and
may not permit any subsidiary of the Corporation to, (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Corporation's capital stock,
(ii) make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Corporation (including other
series of Junior Subordinated Debentures) that rank pari passu with or junior
in interest to the Series A Subordinated Debentures or (iii) make any
guarantee payments with respect to any guarantee by the Corporation of the
debt securities of any subsidiary of the Corporation if such guarantee ranks
pari passu with or junior in interest to the Series A Subordinated Debentures
(other than (a) dividends or distributions in capital stock of the
Corporation, (b) any declaration of a dividend in connection with the
implementation of a stockholders' rights plan or the redemption or repurchase
of any such rights pursuant thereto, (c) payments under the Series A Guarantee
and (d) purchases of common stock related to the issuance of common stock or
rights under any of the Corporation's benefit plans for its directors,
officers or employees, related to the issuance of common stock or rights under
a dividend reinvestment and stock purchase plan, or related to the issuance of
common stock (or securities convertible into or exchangeable for common stock)
as consideration in an acquisition transaction). Prior to the termination of
any such Extension Period, the Corporation may further defer the payment of
interest on the Series A Subordinated Debentures, provided that no Extension
Period may exceed 20 consecutive quarters or extend beyond the Stated Maturity
of the Series A Subordinated Debentures. Upon the termination of any such
Extension Period and the payment of all interest then accrued and unpaid
(together with interest thereon at the rate of   % compounded quarterly, to
the extent permitted by applicable law), the Corporation may elect to begin a
new Extension Period. There is no limitation on the number of times that the
Corporation may elect to begin an Extension Period. See "Certain Terms of
Series A Subordinated Debentures--Option to Defer Interest Payments" and
"Certain Federal Income Tax Consequences--Interest Income and Original Issue
Discount."     
 
  The Corporation has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the Series A
Subordinated Debentures.
 
REDEMPTION
 
  Upon the repayment or redemption, in whole or in part, of the Series A
Subordinated Debentures, whether at Stated Maturity or upon earlier redemption
as provided in the Indenture, the proceeds from
 
                                     S-20
<PAGE>
 
such repayment or redemption shall be applied by the Property Trustee to
redeem a Like Amount (as defined in the accompanying Prospectus) of the Series
A Securities, upon not less than 30 nor more than 60 days notice prior to the
date fixed for repayment or redemption, at a redemption price, with respect to
the Series A Preferred Securities (the "Redemption Price"), equal to the
aggregate Liquidation Amount of such Series A Preferred Securities plus
accumulated and unpaid Distributions thereon to the date of redemption (the
"Redemption Date"). See "Description of Preferred Securities--Redemption or
Exchange" in the accompanying Prospectus. For a description of the Stated
Maturity and redemption provisions of the Series A Subordinated Debentures,
see "Certain Terms of Series A Subordinated Debentures--General" and "--
Redemption."
 
LIQUIDATION OF SERIES A ISSUER AND DISTRIBUTION OF SERIES A SUBORDINATED
DEBENTURES TO HOLDERS
   
  The Corporation will have the right at any time to terminate the Series A
Issuer and cause the Series A Subordinated Debentures to be distributed to the
holders of the Series A Preferred Securities in exchange therefor upon
liquidation of the Series A Issuer. Such right is subject to the Corporation
having received prior approval of the Federal Reserve if then required under
applicable capital guidelines or policies.     
   
  Under current United States federal income tax law, a distribution of Series
A Subordinated Debentures in exchange for the Series A Preferred Securities
should not be a taxable event to holders of the Series A Preferred Securities.
Should there be a change in law, a change in legal interpretation, a Tax Event
or other circumstances, however, the distribution could be a taxable event to
holders of the Series A Preferred Securities. See "Certain Federal Income Tax
Consequences--Distribution of Series A Subordinated Debentures to Holders of
Series A Preferred Securities." If the Corporation elects neither to redeem
the Series A Subordinated Debentures prior to maturity nor to liquidate the
Series A Issuer and distribute the Series A Subordinated Debentures to holders
of the Series A Preferred Securities in exchange therefor, the Series A
Preferred Securities will remain outstanding until the Stated Maturity of the
Series A Subordinated Debentures.     
   
  If the Corporation elects to liquidate the Series A Issuer and thereby
causes the Series A Subordinated Debentures to be distributed to holders of
the Series A Preferred Securities in exchange therefor upon liquidation of the
Series A Issuer, the Corporation shall continue to have the right to shorten
or extend the maturity of the Series A Subordinated Debentures, subject to
certain conditions as described under "Certain Terms of Series A Subordinated
Debentures--General."     
 
LIQUIDATION VALUE
   
  The amount payable on the Series A Preferred Securities in the event of any
liquidation of the Series A Issuer is $25 per Series A Preferred Securities
plus accumulated and unpaid Distributions, which amount may be paid in the
form of a distribution of a like amount in Series A Subordinated Debentures,
subject to certain exceptions. See "Description of Preferred Securities--
Liquidation Distribution Upon Termination" in the accompanying Prospectus.
    
REGISTRATION OF SERIES A PREFERRED SECURITIES
   
  The Series A Preferred Securities will be represented by global certificates
registered in the name of DTC or its nominee. Beneficial interests in the
Series A Preferred Securities will be shown on, and transfers thereof will be
effected only through, records maintained by participants in DTC. Except as
described below and in the accompanying Prospectus, Series A Preferred
Securities in certificated form will not be issued in exchange for the global
certificates. See "Book-Entry Issuance" in the accompanying Prospectus.     
 
                                     S-21
<PAGE>
 
   
  A global security shall be exchangeable for Series A Preferred Securities
registered in the names of persons other than DTC or its nominee only if (i)
DTC notifies the Series A Issuer that it is unwilling or unable to continue as
a depositary for such global security and no successor depositary shall have
been appointed, or if at any time DTC ceases to be a clearing agency
registered under the Exchange Act at a time when DTC is required to be so
registered to act as such depositary, (ii) the Issuer in its sole discretion
determines that such global security shall be so exchangeable or (iii) there
shall have occurred and be continuing an event of default under the Indenture
with respect to the Series A Subordinated Debentures. Any global security that
is exchangeable pursuant to the preceding sentence shall be exchangeable for
definitive certificates registered in such names as DTC shall direct. It is
expected that such instructions will be based upon directions received by DTC
from its Participants (as defined in the accompanying Prospectus) with respect
to ownership of beneficial interests in such global security. In the event
that Series A Preferred Securities are issued in definitive form, such Series
A Preferred Securities will be in denominations of $25 and integral multiples
thereof and may be transferred or exchanged at the offices described below.
       
  Payments on Series A Preferred Securities represented by a global security
will be made to DTC, as the depositary for the Series A Preferred Securities.
In the event Series A Preferred Securities are issued in certificated form,
the Liquidation Amount and Distributions will be payable, the transfer of the
Series A Preferred Securities will be registrable, and Series A Preferred
Securities will be exchangeable for Series A Preferred Securities of other
denominations of a like aggregate Liquidation Amount, at the corporate office
of the Property Trustee in New York, New York, or at the offices of any paying
agent or transfer agent appointed by the Administrative Trustees, provided
that payment of any Distribution may be made at the option of the
Administrative Trustees by check mailed to the address of the persons entitled
thereto or by wire transfer. In addition, if the Series A Preferred Securities
are issued in certificated form, the record dates for payment of Distributions
will be the 15th day of the month in which the relevant Distribution payment
is scheduled to be paid. For a description of DTC and the terms of the
depositary arrangements relating to payments, transfers, voting rights,
redemptions and other notices and other matters, see "Book-Entry Issuance" in
the accompanying Prospectus.     
 
               CERTAIN TERMS OF SERIES A SUBORDINATED DEBENTURES
 
GENERAL
   
  The following summary of certain terms and provisions of the Series A
Subordinated Debentures supplements the description of the terms and
provisions of the Corresponding Junior Subordinated Debentures (as defined in
the accompanying Prospectus) set forth in the accompanying Prospectus under
the heading "Description of Junior Subordinated Debentures", to which
description reference is hereby made. The summary of certain terms and
provisions of the Series A Subordinated Debentures set forth below, which
describes the material provisions thereof, does not purport to be complete and
is subject to, and is qualified in its entirety by reference to, the Indenture
to which reference is hereby made. The form of Indenture has been filed as an
exhibit to the Registration Statement of which this Prospectus Supplement and
accompanying Prospectus form a part.     
   
  Concurrently with the issuance of the Series A Preferred Securities, the
Series A Issuer will invest the proceeds thereof, together with the
consideration paid by the Corporation for the Series A Common Securities, in
the Series A Subordinated Debentures issued by the Corporation. The Series A
Subordinated Debentures will bear interest at the annual rate of   % of the
principal amount thereof, payable quarterly in arrears on March 31, June 30,
September 30 and December 31 of each year (each, an "Interest Payment Date"),
commencing March 31, 1997, to the person in whose name each Series A
Subordinated Debenture is registered, subject to certain exceptions, at the
close of     
 
                                     S-22
<PAGE>
 
   
business on the Business Day next preceding such Interest Payment Date. It is
anticipated that, until the liquidation, if any, of the Series A Issuer, each
of the Series A Subordinated Debentures will be held in the name of the
Property Trustee in trust for the benefit of the holders of the Series A
Preferred Securities. The amount of interest payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months. In the event
that any date on which interest is payable on the Series A Subordinated
Debentures is not a Business Day, then payment of the interest payable on such
date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on the date such payment was
originally payable. Accrued interest that is not paid on the applicable
Interest Payment Date will bear additional interest on the amount thereof (to
the extent permitted by law) at the rate per annum of   % thereof, compounded
quarterly from the relevant Interest Payment Date. The term "interest" as used
herein shall include quarterly interest payments, interest on quarterly
interest payments not paid on the applicable Interest Payment Date and
Additional Sums (as defined below), as applicable.     
   
  The Series A Subordinated Debentures will be issued as a series of junior
subordinated deferrable interest debentures under the Indenture. The Series A
Subordinated Debentures will mature on March 31, 2027 (such date, as it may be
shortened or extended as hereinafter described, the "Stated Maturity"). Such
date may be shortened at any time by the Corporation to any date not earlier
than December   , 2001, subject to the Corporation having received prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies. Such date may also be extended at any time at the
election of the Corporation to any date not later than March 31, 2046,
provided that at the time such election is made and at the time of extension
(i) the Corporation is not in bankruptcy, otherwise insolvent or in
liquidation, (ii) the Corporation is not in default in the payment of any
interest or principal on the Series A Subordinated Debentures, (iii) if the
Series A Issuer has not been liquidated, the Series A Issuer is not in arrears
on payments of Distributions on the Series A Preferred Securities and no
deferred Distributions are accumulated and (iv) the Series A Subordinated
Debentures are rated not less than BBB- by Standard & Poor's Ratings Services
or Baa3 by Moody's Investors Service, Inc. or the equivalent by any other
nationally recognized statistical rating organization. In the event the
Corporation elects to shorten or extend the maturity of the Series A
Subordinated Debentures, it shall give notice to the Debenture Trustee, and
the Debenture Trustee shall give notice of such shortening or extension to the
holders of the Series A Subordinated Debentures no more than 30 and no less
than 60 days prior to the effectiveness thereof.     
   
  The Series A Subordinated Debentures will be unsecured and will rank junior
and be subordinate in right of payment to all Senior Debt of the Corporation.
See "Description of Junior Subordinated Debentures--Subordination." At
September 30, 1996 the aggregate amount of Senior Debt outstanding was
approximately $2.689 billion. Because the Corporation is a holding company,
the right of the Corporation to participate in any distribution of assets of
any subsidiary, including Mellon Bank, N.A., The Dreyfus Corporation and The
Boston Company, Inc., upon such subsidiary's liquidation or reorganization or
otherwise subject to the prior claims of creditors of that subsidiary, except
to the extent that the Corporation may itself be recognized as a creditor of
that subsidiary. Accordingly, the Series A Subordinated Debentures will be
effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and holders of Series A Subordinated Debentures
should look only to the assets of the Corporation for payments on the Series A
Subordinated Debentures. The Indenture does not limit the incurrence or
issuance of other secured or unsecured debt of the Corporation, including
Senior Debt, whether under the Indenture, any existing indenture or any other
indenture that the Corporation may enter into in the future or otherwise. See
"Description of Junior Subordinated Debentures--Subordination" in the
accompanying Prospectus.

<PAGE>
 
   
OPTION TO DEFER INTEREST PAYMENTS     
   
  So long as no event of default under the Indenture has occurred and is
continuing, the Corporation has the right under the Indenture at any time or
from time to time during the term of the Series A Subordinated Debentures to
defer payment of interest on the Series A Subordinated Debentures for a period
not exceeding 20 consecutive quarters with respect to each Extension Period,
provided that no Extension Period may extend beyond the Stated Maturity of the
Series A Subordinated Debentures. At the end of such Extension Period, the
Corporation must pay all interest then accrued and unpaid on the Series A
Subordinated Debentures (together with interest on such unpaid interest at the
annual rate of   %, compounded quarterly from the relevant Interest Payment
Date, to the extent permitted by applicable law). During an Extension Period,
interest will accrue and holders of Series A Subordinated Debentures (or
holders of Series A Preferred Securities while such series is outstanding)
will be required to accrue interest income for United States federal income
tax purposes. See "Certain Federal Income Tax Consequences--Interest Income
and Original Issue Discount."     
   
  During any such Extension Period, the Corporation may not, and may not
permit any subsidiary of the Corporation to, (i) declare or pay any dividends
or distributions on, or redeem, purchase, acquire, or make a liquidation
payment with respect to, any of the Corporation's capital stock, (ii) make any
payment of principal, interest or premium, if any, on or repay, repurchase or
redeem any debt securities of the Corporation (including other series of
Junior Subordinated Debentures) that rank pari passu with or junior in
interest to the Series A Subordinated Debentures or (iii) make any guarantee
payments with respect to any guarantee by the Corporation of the debt
securities of any subsidiary of the Corporation if such guarantee ranks pari
passu with or junior in interest to the Series A Subordinated Debentures
(other than (a) dividends or distributions in capital stock of the
Corporation, (b) any declaration of a dividend in connection with the
implementation of a stockholders' rights plan or the redemption or repurchase
of any such rights pursuant thereto, (c) payments under the Series A Guarantee
and (d) purchases of common stock related to the issuance of common stock or
rights under any of the Corporation's benefit plans for its directors,
officers or employees). Prior to the termination of any such Extension Period,
the Corporation may further defer the payment of interest on the Series A
Subordinated Debentures, provided that no Extension Period may exceed 20
consecutive quarters or extend beyond the Stated Maturity of the Series A
Subordinated Debentures. Upon the termination of any such Extension Period and
the payment of all interest then accrued and unpaid (together with interest
thereon at the rate of  %, compounded quarterly, to the extent permitted by
applicable law), the Corporation may elect to begin a new Extension Period
subject to the above requirements. No interest shall be due and payable during
an Extension Period, except at the end thereof. The Corporation must give the
Property Trustee, the Administrative Trustees and the Debenture Trustee notice
of its election to begin such Extension Period at least one Business Day prior
to the earlier of (i) the date interest on the Series A Subordinated
Debentures would have been payable except for the election to begin such
Extension Period, (ii) the date the Administrative Trustees are required to
give notice to the New York Stock Exchange, the Nasdaq National Market or
other applicable stock exchange or automated quotation system on which the
Series A Preferred Securities are then listed or quoted or to holders of
Series A Subordinated Debentures of the record date or (iii) the date such
Distributions are payable, but in any event not less than one Business Day
prior to such record date. The Debenture Trustee shall give notice of the
Corporation's election to begin a new Extension Period to the holders of the
Series A Subordinated Debentures. There is no limitation on the number of
times that the Corporation may elect to begin an Extension Period. See
"Description of Junior Subordinated Debentures--Option to Defer Interest
Payments" in the accompanying Prospectus.     
 
ADDITIONAL SUMS
 
  If the Series A Issuer is required to pay any additional taxes, duties or
other governmental charges as a result of a Tax Event, the Corporation will
pay as additional amounts on the Series A
 
                                     S-24
<PAGE>
 
Subordinated Debentures such amounts as shall be required so that the
Distributions payable by the Series A Issuer shall not be reduced as a result
of any such additional taxes, duties or other governmental charges.
 
REDEMPTION
   
  Subject to the Corporation having received prior approval of the Federal
Reserve if then required under applicable capital guidelines or policies, the
Series A Subordinated Debentures are redeemable prior to maturity at the
option of the Corporation (i) on or after December   , 2001, in whole at any
time or in part from time to time, or (ii) at any time in whole (but not in
part) prior to December   , 2001 and within 90 days following the occurrence
and continuation of a Tax Event or Capital Treatment Event, in either case at
a redemption price equal to the accrued and unpaid interest on the Series A
Subordinated Debentures so redeemed to the date fixed for redemption, plus
100% of the principal amount thereof. See "Description of Junior Subordinated
Debentures--Redemption" in the accompanying Prospectus.     
 
DISTRIBUTION OF SERIES A SUBORDINATED DEBENTURES
   
  As described under "Certain Terms of Series A Preferred Securities--
Liquidation of Issuer and Distribution of Series A Subordinated Debentures to
Holders", under certain circumstances involving the termination of the Series
A Issuer, Series A Subordinated Debentures may be distributed to the holders
of the Series A Preferred Securities in exchange therefor upon liquidation of
the Series A Issuer after satisfaction of liabilities to creditors of the
Series A Issuer as provided by applicable law. If distributed to holders of
Series A Preferred Securities, the Series A Subordinated Debentures will
initially be issued in the form of one or more global securities and DTC, or
any successor depositary for the Series A Preferred Securities, will act as
depositary for the Series A Subordinated Debentures. It is anticipated that
the depositary arrangements for the Series A Subordinated Debentures would be
substantially identical to those in effect for the Series A Preferred
Securities. If Series A Subordinated Debentures are distributed to the holders
of Series A Preferred Securities in exchange therefor upon the liquidation of
the Series A Issuer, the Corporation will use its best efforts to list the
Series A Subordinated Debentures on the New York Stock Exchange or such other
stock exchanges or automated quotation system, if any, on which the Series A
Preferred Securities are then listed or quoted. There can be no assurance as
to the market price of any Series A Subordinated Debentures that may be
distributed to the holders of Series A Preferred Securities.     
 
REGISTRATION OF SERIES A SUBORDINATED DEBENTURES
 
  The Series A Subordinated Debentures will be represented by global
certificates registered in the name of DTC or its nominee. Beneficial
interests in the Series A Subordinated Debentures will be shown on, and
transfers thereof will be effected only through, records maintained by
participants in DTC. Except as described below and in the accompanying
Prospectus, Series A Subordinated Debentures in certificated form will not be
issued in exchange for the global certificates. See "Book-Entry Issuance" in
the accompanying Prospectus.
   
  A global security shall be exchangeable for Series A Subordinated Debentures
registered in the names of persons other than DTC or its nominee only if (i)
DTC notifies the Corporation that it is unwilling or unable to continue as a
depositary for such global security and no successor depositary shall have
been appointed, or if at any time DTC ceases to be a clearing agency
registered under the Exchange Act at a time when DTC is required to be so
registered to act as such depositary, (ii) the Corporation in its sole
discretion determines that such global security shall be so exchangeable, or
(iii) there shall have occurred and be continuing an Event of Default under
the Indenture with respect to the Series A Subordinated Debenture. Any global
security that is exchangeable pursuant to the     
 
                                     S-25
<PAGE>
 
preceding sentence shall be exchangeable for definitive certificates
registered in such names as DTC shall direct. It is expected that such
instructions will be based upon directions received by DTC from its
Participants (as defined in the accompanying Prospectus) with respect to
ownership of beneficial interests in such global security. In the event that
Series A Subordinated Debentures are issued in definitive form, such Series A
Subordinated Debentures will be in denominations of $25 and integral multiples
thereof and may be transferred or exchanged at the offices described below.
   
  Payments on Series A Subordinated Debentures represented by a global
security will be made to DTC, as the depositary for the Series A Subordinated
Debentures. In the event Series A Subordinated Debentures are issued in
certificated form, principal and interest will be payable, the transfer of the
Series A Subordinated Debentures will be registrable, and Series A
Subordinated Debentures will be exchangeable for Series A Subordinated
Debentures of other denominations of a like aggregate principal amount, at the
corporate office of the Debenture Trustee in New York, New York, or at the
offices of any paying agent or transfer agent appointed by the Corporation,
provided that payment of interest may be made at the option of the Corporation
by check mailed to the address of the persons entitled thereto or by wire
transfer. In addition, if the Series A Subordinated Debentures are issued in
certificated form, the record dates for payment of interest will be the 15th
day of the last month of each calendar quarter. For a description of DTC and
the terms of the depositary arrangements relating to payments, transfers,
voting rights, redemptions and other notices and other matters, see "Book-
Entry Issuance" in the accompanying Prospectus.     
                      
                   CERTAIN TERMS OF SERIES A GUARANTEE     
   
  The Series A Guarantee guarantees to the holders of the Series A Securities
the following payments, to the extent not paid by the Series A Issuer: (i) any
accumulated and unpaid Distributions required to be paid on the Series A
Securities, to the extent that the Series A Issuer has funds on hand available
therefor at such time, (ii) the redemption price with respect to any Series A
Securities called for redemption, to the extent that the Series A Issuer has
funds on hand available therefor at such time, and (iii) upon a voluntary or
involuntary dissolution, winding-up or liquidation of the Series A Issuer
(unless the Series A Subordinated Debentures are distributed to holders of the
Series A Securities), the lesser of (a) the aggregate of the Liquidation
Amount and all accumulated and unpaid Distributions to the date of payment, to
the extent that the Series A Issuer has funds on hand available therefor at
such time, and (b) the amount of assets of the Series A Issuer remaining
available for distribution to holders of the Series A Securities after payment
of creditors of the Series A Issuer as required by applicable law. The Series
A Guarantee will be qualified as an indenture under the Trust Indenture Act.
The Chase Manhattan Bank will act as the Guarantee Trustee for the purposes of
compliance with the Trust Indenture Act and will hold the Series A Guarantee
for the benefit of the holders of the Series A Securities. The Chase Manhattan
Bank will also act as Debenture Trustee for the Series A Subordinated
Debentures and as Property Trustee.     
   
  The holders of not less than a majority in aggregate liquidation amount of
the Series A Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect to the Series A Guarantee or to direct the exercise of any trust power
conferred upon the Guarantee Trustee under the Series A Guarantee. Any holder
of the Series A Securities may institute a legal proceeding directly against
the Corporation to enforce its rights under the Series A Guarantee without
first instituting a legal proceeding against the Series A Issuer, the
Guarantee Trustee or any other person or entity. If the Corporation were to
default on its obligation to pay amounts payable under the Series A
Subordinated Debentures, the Series A Issuer would lack funds for the payment
of Distributions or amounts payable on redemption of the Series A Securities
or otherwise, and, in such event, holders of the Series A Securities would not
be able to rely upon the Series A Guarantee for payment of such amounts.
Instead, if any event of default under the Indenture shall have occurred and
be continuing and such event is attributable to the failure of the     
 
                                     S-26
<PAGE>
 
   
Corporation to pay interest on or principal of the Series A Subordinated
Debentures on the applicable payment date, then a holder of Series A
Securities may institute a Direct Action against the Corporation pursuant to
the terms of the Indenture for enforcement of payment to such holder of the
principal of or interest on such Series A Subordinated Debentures having a
principal amount equal to the aggregate Liquidation Amount of the Series A
Securities of such holder. In connection with such Direct Action, the
Corporation will have a right of set-off under the Indenture to the extent of
any payment made by the Corporation to such holder of Series A Securities in
the Direct Action. Except as described herein, holders of Series A Securities
will not be able to exercise directly any other remedy available to the
holders of the Series A Subordinated Debentures or assert directly any other
rights in respect of the Series A Subordinated Debentures. See "Description of
Guarantees" in the accompanying Prospectus. The Trust Agreement provides that
each holder of Series A Securities by acceptance thereof agrees to the
provisions of the Series A Guarantee, the Expense Agreement and the Indenture.
    
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of the principal United States federal income tax
consequences of the purchase, ownership and disposition of Series A Preferred
Securities. This summary only addresses the tax consequences to a person that
acquires Series A Preferred Securities on their original issue at their
original offering price and that is (i) an individual citizen or resident of
the United States, (ii) a corporation or partnership organized in or under the
laws of the United States or any state thereof or the District of Columbia or
(iii) an estate or trust the income of which is subject to United States
federal income tax regardless of source (a "United States Person"). This
summary does not address all tax consequences that may be applicable to a
United States Person that is a beneficial owner of Series A Preferred
Securities, nor does it address the tax consequences to (i) persons that are
not United States Persons, (ii) persons that may be subject to special
treatment under United States federal income tax law, such as banks, insurance
companies, thrift institutions, regulated investment companies, real estate
investment trusts, tax-exempt organizations and dealers in securities or
currencies, (iii) persons that will hold Series A Preferred Securities as part
of a position in a "straddle" or as part of a "hedging," "conversion" or other
integrated investment transaction for federal income tax purposes, (iv)
persons whose functional currency is not the United States dollar or (v)
persons that do not hold Series A Preferred Securities as capital assets.
 
  The statements of law or legal conclusion set forth in this summary
constitute the opinion of Sullivan & Cromwell, special tax counsel to the
Corporation and the Series A Issuer. This summary is based upon the Internal
Revenue Code of 1986, as amended (the "Code"), Treasury Regulations, Internal
Revenue Service rulings and pronouncements and judicial decisions now in
effect, all of which are subject to change at any time. Such changes may be
applied retroactively in a manner that could cause the tax consequences to
vary substantially from the consequences described below, possibly adversely
affecting a beneficial owner of Series A Preferred Securities. In particular,
legislation has been proposed that could adversely affect the Corporation's
ability to deduct interest on the Series A Subordinated Debentures, which may
in turn permit the Corporation to cause a redemption of the Series A Preferred
Securities. See "--Possible Tax Law Changes." The authorities on which this
summary is based are subject to various interpretations, and it is therefore
possible that the federal income tax treatment of the purchase, ownership and
disposition of Series A Preferred Securities may differ from the treatment
described below.
 
  PROSPECTIVE INVESTORS ARE ADVISED TO CONSULT WITH THEIR OWN TAX ADVISORS IN
LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES AS TO THE FEDERAL TAX CONSEQUENCES
OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF SERIES A PREFERRED SECURITIES,
AS WELL AS THE EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.
 
                                     S-27
<PAGE>
 
CLASSIFICATION OF THE SERIES A ISSUER
   
  Under current law and assuming compliance with the terms of the Trust
Agreement, the Series A Issuer will not be classified as an association
taxable as a corporation for United States federal income tax purposes. As a
result, each beneficial owner of Series A Preferred Securities (a
"Securityholder") will be required to include in its gross income its pro rata
share of the interest income, including original issue discount, paid or
accrued with respect to the Series A Subordinated Debentures whether or not
cash is actually distributed to the Securityholders. See "Interest Income and
Original Issue Discount."     
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
   
  Under recently issued Treasury regulations applicable to debt instruments
issued on or after August 13, 1996 (the "Regulations"), a "remote" contingency
that stated interest will not be timely paid will be ignored in determining
whether a debt instrument is issued with original issue discount ("OID"). The
Corporation believes that the likelihood of its exercising its option to defer
payments is remote. Based on the foregoing, the Corporation believes that the
Series A Subordinated Debentures will not be considered to be issued with OID
at the time of their original issuance and, accordingly, a Securityholder
should include in gross income such Securityholder's allocable share of
interest on the Series A Subordinated Debentures.     
   
  Under the Regulations, if the Corporation exercised its option to defer any
payment of interest, the Series A Subordinated Debentures would at that time
be treated as issued with OID, and all stated interest on the Series A
Subordinated Debentures would thereafter be treated as OID as long as the
Series A Subordinated Debentures remained outstanding. In such event, all of a
holder's taxable interest income with respect to the Series A Subordinated
Debentures would be accounted for as OID on an economic accrual basis
regardless of such Securityholder's method of tax accounting, and actual
distributions of stated interest would not be reported as taxable income.
Consequently, a Securityholder would be required to include in gross income
OID even though the Corporation would not make any actual cash payments during
an Extension Period.     
 
  The Regulations have not been addressed in any rulings or other
interpretations by the Internal Revenue Service (the "IRS"), and it is
possible that the IRS could take a position contrary to the interpretation
herein.
   
  Because income on the Series A Preferred Securities will constitute interest
or OID, corporate Securityholders will not be entitled to a dividends-received
deduction with respect to any income recognized with respect to the Series A
Preferred Securities.     
   
  Subsequent uses of the term "interest" in this summary include income in the
form of OID.     
 
DISTRIBUTION OF SERIES A SUBORDINATED DEBENTURES TO HOLDERS OF SERIES A
PREFERRED SECURITIES
   
  Under current law, a distribution by the Series A Issuer of the Series A
Subordinated Debentures as described under the caption "Certain Terms of
Series A Preferred Securities--Liquidation of Series A Issuer and Distribution
of Series A Subordinated Debentures to Holders" will be non-taxable and will
result in the Securityholder receiving directly its pro rata share of the
Series A Subordinated Debentures previously held indirectly through the Series
A Issuer, with a holding period and aggregate tax basis equal to the holding
period and aggregate tax basis such Securityholder had in its Series A
Preferred Securities before such distribution. If, however, the liquidation of
the Series A Issuer were to occur because the Series A Issuer is subject to
United States federal income tax with respect to income accrued or received on
the Series A Subordinated Debentures, the distribution of Series A
Subordinated Debentures to Securityholders by the Series A Issuer would be a
taxable event to the Series A Issuer and each Securityholder, and the
Securityholder would recognize gain or loss as if the     
 
                                     S-28
<PAGE>
 
   
Securityholder had exchanged its Series A Preferred Securities for the Series
A Subordinated Debentures it received upon the liquidation of the Series A
Issuer. A Securityholder will include interest in income in respect of Series
A Subordinated Debentures received from the Series A Issuer in the manner
described above under "Interest Income and Original Issue Discount."     
 
SALES OR REDEMPTION OF SERIES A PREFERRED SECURITIES
   
  A Securityholder that sells (including a redemption for cash) Series A
Preferred Securities will recognize gain or loss equal to the difference
between its adjusted tax basis in the Series A Preferred Securities and the
amount realized on the sale of such Series A Preferred Securities. Assuming
that the Corporation does not exercise its option to defer payment of interest
on the Series A Subordinated Debentures, and the Series A Preferred Securities
are not considered issued with OID, a Securityholder's adjusted tax basis in
the Series A Preferred Securities generally will be its initial purchase
price. If the Series A Subordinated Debentures are deemed to be issued with
OID as a result of the Corporation's deferral of any interest payment or
otherwise, a Securityholder's tax basis in the Series A Preferred Securities
generally will be its initial purchase price, increased by OID previously
includible in such Securityholder's gross income to the date of disposition
and decreased by distributions or other payments received on the Series A
Preferred Securities since and including the date of the first Extension
Period. Such gain or loss generally will be a capital gain or loss (except to
the extent any amount realized is treated as a payment of accrued interest
with respect to such holder's pro rata share of the Series A Subordinated
Debentures required to be included in income) and generally will be a long-
term capital gain or loss if the Series A Preferred Securities have been held
for more than one year.     
   
  Should the Corporation exercise its option to defer any payment of interest
on the Series A Subordinated Debentures, the Series A Preferred Securities may
trade at a price that does not accurately reflect the value of accrued but
unpaid interest with respect to the underlying Series A Subordinated
Debentures. In the event of such a deferral, a Securityholder who disposes of
its Series A Preferred Securities between record dates for payments of
distributions thereon will be required to include in income as ordinary income
accrued but unpaid interest on the Series A Subordinated Debentures to the
date of disposition as OID and to add such amount to its adjusted tax basis in
its pro rata share of the underlying Series A Subordinated Debentures deemed
disposed of. To the extent the selling price is less than the holder's
adjusted tax basis, such Securityholder will recognize a capital loss. Subject
to certain limited exceptions, capital losses cannot be applied to offset
ordinary income for United States federal income tax purposes.     
 
BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
   
  The amount of interest income paid or accrued on the Series A Preferred
Securities held of record by United States Persons (other than corporations
and other exempt Securityholders) will be reported to the IRS. "Backup"
withholding at a rate of 31% will apply to payments of interest to non- exempt
United States Persons unless the Securityholder furnishes its taxpayer
identification number in the manner prescribed in applicable Treasury
Regulations, certifies that such number is correct, certifies as to no loss of
exemption from backup withholding and meets certain other conditions.     
 
  Payment of the proceeds from the disposition of Series A Preferred
Securities to or through the United States office of a broker is subject to
information reporting and backup withholding unless the holder or beneficial
owner establishes an exemption from information reporting and backup

  It is anticipated that income on the Series A Preferred Securities will be

Preferred Securities by January 31 following each calendar year.
 
POSSIBLE TAX LAW CHANGES
   
  On March 19, 1996, President Clinton proposed legislation (the "Proposed
Legislation") that would have, among other things, generally denied corporate
issuers a deduction for interest in respect of certain debt obligations, such
as the Series A Subordinated Debentures, issued on or after December 7, 1995.
On March 29, 1996, Senate Finance Committee Chairman William V. Roth, Jr. and
House Ways and Means Committee Chairman Bill Archer issued a joint statement
(the "Joint Statement") indicating their intent that the Proposed Legislation,
if adopted by either of the tax-writing committees of Congress, would have an
effective date that is no earlier than the date of "appropriate Congressional
action." Based upon the Joint Statement, it is expected that if the Proposed
Legislation were to be enacted, such legislation would not apply to the Series
A Subordinated Debentures. There can be no assurances, however, that the
effective date guidance contained in the Joint Statement will be incorporated
into the Proposed Legislation, if enacted, or that other legislation enacted
after the date hereof will not otherwise adversely affect the ability of the
Corporation to deduct the interest payable on the Series A Subordinated
Debentures. Accordingly, there can be no assurance that a Tax Event will not
occur. See "Description of Preferred Securities--Redemption or Exchange--Tax
Event Redemption" in the accompanying Prospectus.

  Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all the Series A Preferred
Securities offered hereby, if any are taken.
 
  The Underwriters propose initially to offer the Series A Preferred
Securities to the public at the public offering price set forth on the cover
page of this Prospectus Supplement and to certain dealers at such price less a
concession not in excess of $.   per Series A Preferred Securities. The
Underwriters may allow, and such dealers may reallow, a discount not in excess
of $.   per Series A Preferred Securities to certain other dealers. After the
initial public offering, the public offering price, concession and discount
may be changed.
   
  In view of the fact that the proceeds from the sale of the Series A
Preferred Securities will be used to purchase the Series A Subordinated
Debentures issued by the Corporation, the Underwriting Agreement provides that
the Corporation will pay as Underwriters' compensation for the Underwriters'
arranging the investment therein of such proceeds an amount of $.   per Series
A Preferred Securities for the accounts of the several Underwriters.     
   
  The Corporation and the Series A Issuer have agreed that, during the period
beginning from the date of the Underwriting Agreement and continuing to and
including the earlier of (i) the termination of trading restrictions on the
Series A Preferred Securities, as determined by the Underwriters, and (ii) 30
days after the closing date, they will not offer, sell, contract to sell or
otherwise dispose of any Preferred Securities, any other beneficial interests
in the assets of the Series A Issuer, or any preferred securities or any other
securities of the Series A Issuer or the Corporation which are substantially
similar to the Series A Preferred Securities, including any guarantee of such
securities, or any securities convertible into or exchangeable for or
representing the right to receive preferred securities or any such
substantially similar securities of either the Series A Issuer or the
Corporation, without the prior written consent of the Underwriters, except for
the Series A Preferred Securities offered in connection with this offering.
       
  Prior to this offering, there has been no public market for the Series A
Preferred Securities. Application will be made to list the Series A Preferred
Securities on the New York Stock Exchange. Trading of the Series A Preferred
Securities on the New York Stock Exchange is expected to commence within a 30-
day period after the initial delivery of the Series A Preferred Securities.
The Underwriters     
 
                                     S-31
<PAGE>
 
have advised the Corporation that they intend to make a market in the Series A
Preferred Securities prior to commencement of trading on the New York Stock
Exchange, but are not obligated to do so and may discontinue market making at
any time without notice. No assurance can be given as to the liquidity of the
trading market for the Series A Preferred Securities.
 
  In order to meet one of the requirements for listing the Series A Preferred
Securities on the New York Stock Exchange, the Underwriters will undertake to
sell lots of 100 or more Series A Preferred Securities to a minimum of 400
beneficial holders.
 
  The Corporation and the Series A Issuer have agreed to indemnify the several
Underwriters against, or contribute to payments that the Underwriters may be
required to make in respect of, certain liabilities, including liabilities
under the Securities Act of 1933, as amended.
 
  Certain of the Underwriters or their affiliates have provided from time to
time, and expect to provide in the future, investment or commercial banking
services to the Corporation and its affiliates, for which such Underwriters or
their affiliates have received or will receive customary fees and commissions.
 
                            VALIDITY OF SECURITIES
   
  Certain matters of Delaware law relating to the validity of the Series A
Preferred Securities, the enforceability of the Trust Agreement and the
formation of the Series A Issuer will be passed upon by Richards, Layton &
Finger, One Rodney Square, Wilmington, Delaware 19801, special Delaware
Counsel to the Corporation and the Series A Issuer. The validity of the Series
A Guarantee and the Series A Subordinated Debentures will be passed upon for
the Corporation by Carl Krasik, Esq., Associate General Counsel and Secretary
of the Corporation, One Mellon Bank Center, Pittsburgh, Pennsylvania 15258,
and for the Underwriters by Sullivan & Cromwell, 125 Broad Street, New York,
New York 10004. Mr. Krasik and Sullivan & Cromwell will rely on the opinion of
Richards, Layton & Finger as to matters of Delaware law, and Sullivan &
Cromwell will rely on the opinion of Mr. Krasik as to matters of Pennsylvania
law. Certain matters relating to United States federal income tax
considerations described in this Prospectus Supplement will be passed upon for
the Corporation by Sullivan & Cromwell, as special tax counsel for the
Corporation. Sullivan & Cromwell from time to time performs legal services for
the Corporation. At September 30, 1996, Mr. Krasik held options covering 5,950
shares of the Corporation's Common Stock.

  Mellon Bank Corporation, a Pennsylvania corporation (the "Corporation"), may
from time to time offer in one or more series or issuances its junior
subordinated deferrable interest debentures (the "Junior Subordinated
Debentures"). The Junior Subordinated Debentures will be unsecured and
subordinate and junior in right of payment to all Senior Debt (as defined in
"Description of Junior Subordinated Debentures--Subordination") of the
Corporation. If provided in an accompanying Prospectus Supplement, the
Corporation will have the right to defer payments of interest on any series of
Junior Subordinated Debentures by extending the interest payment period thereon
at any time or from time to time for up to such number of consecutive interest
payment periods (which shall not extend beyond the Stated Maturity (as defined
herein) of the Junior Subordinated Debentures) with respect to each deferral
period as may be specified in such Prospectus Supplement (each, an "Extension
Period"). In such circumstances, however, the Corporation would not be
permitted, subject to certain exceptions set forth herein, to declare or pay
any dividends, distributions or other payments with respect to, or repay,
repurchase, redeem or otherwise acquire, the Corporation's capital stock or
debt securities that rank pari passu with or junior to such series or Junior
Subordinated Debentures. See "Description of Junior Subordinated Debentures--
Option to Defer Interest Payments" and "--Restrictions on Certain Payments.".
       
  Mellon Capital I, Mellon Capital II and Mellon Capital III, each a trust
created under the laws of the State of Delaware (each, an "Issuer," and
collectively, the "Issuers"), may severally offer, from time to time, preferred
securities (the "Preferred Securities") representing beneficial ownership
interests in such Issuer. The Corporation will be the owner of the common
securities (the "Common Securities" and, together with the Preferred
Securities, the "Trust Securities") representing common beneficial ownership
interests in such Issuer. Holders of the Preferred Securities will be entitled
to receive preferential cumulative cash distributions ("Distributions")
accumulating from the date of original issuance and payable periodically as
specified in an accompanying Prospectus Supplement. Concurrently with the
issuance by an Issuer of its Preferred Securities, such Issuer will invest the
proceeds thereof and of contributions received in respect of the Common
Securities in a corresponding series of the Corporation's Junior Subordinated
Debentures (the "Corresponding Junior Subordinated Debentures") with terms
corresponding to the terms of that Issuer's Preferred Securities (the "Related
Preferred Securities").

(cover page continued)
          
  Accordingly, if as provided in an accompanying Prospectus Supplement, the
Corporation has the right to defer the payment of interest on a series of
Corresponding Junior Subordinated Debentures, then, if interest payments are
so deferred, Distributions on the Related Preferred Securities would also be
deferred, but would continue to accumulate at the rate per annum set forth in
the related Prospectus Supplement. See "Description of Preferred Securities--
Distributions".     
   
  Taken together, the Corporation's obligations under each series of
Corresponding Junior Subordinated Debentures, the Indenture, the related Trust
Agreement, the related Expense Agreement and the related Guarantee (each, as
defined herein), in the aggregate, provide a full, irrevocable and
unconditional guarantee of payments of Distributions and other amounts due on
the Related Preferred Securities. See "Relationship Among the Preferred
Securities, the Corresponding Junior Subordinated Debentures, the Expense
Agreement and the Guarantees--Full and Unconditional Guarantee". The payment
of Distributions with respect to the Preferred Securities of each Issuer and
payments on liquidation of such Issuer or redemption of such Preferred
Securities, in each case out of funds held by such Issuer, are each
irrevocably guaranteed by the Corporation to the extent described herein
(each, a "Guarantee"). See "Description of Guarantees." The obligations of the
Corporation under each Guarantee will be unsecured and subordinated and junior
in right of payment to all Senior Debt of the Corporation.     
   
  The Corresponding Junior Subordinated Debentures and the right to
reimbursement of expenses under the related Expense Agreement (as defined
herein) will be the sole assets of each Issuer, and payments under the
Corresponding Junior Subordinated Debentures and the related Expense Agreement
will be the only revenue of each Issuer. If so provided in an accompanying
Prospectus Supplement, the Corporation may, upon receipt of approval of the
Federal Reserve (if such approval is then required under the applicable
capital guidelines or policies), redeem the Corresponding Junior Subordinated
Debentures (and thereby cause the redemption of the Trust Securities) or may
terminate each Issuer and, after satisfaction of liabilities to the creditors
of such Issuer as required by applicable law, cause the Corresponding Junior
Subordinated Debentures to be distributed to the holders of Preferred
Securities in exchange therefor upon liquidation of their interests in such
Issuer. See "Description of Preferred Securities--Liquidation Distribution
Upon Termination."     
   
  The Junior Subordinated Debentures and Preferred Securities may be offered
in amounts, at prices and on terms to be determined at the time of offering;
provided, however, the aggregate initial public offering price of all Junior
Subordinated Debentures (other than Corresponding Junior Subordinated
Debentures) and Preferred Securities (including the Corresponding Junior
Subordinated Debentures) issued pursuant to the Registration Statement of
which this Prospectus forms a part shall not exceed $500,000,000. Certain
specific terms of the Junior Subordinated Debentures or Preferred Securities
in respect of which this Prospectus is being delivered will be described in an
accompanying Prospectus Supplement, including without limitation and where
applicable and to the extent not set forth herein, (a) in the case of Junior
Subordinated Debentures, the specific designation, aggregate principal amount,
denominations, Stated Maturity (including any provisions for the shortening or
extension thereof), interest payment dates, interest rate (which may be fixed
or variable) or method of calculating interest, if any, applicable Extension
Period or interest deferral terms, if any, place or places where principal,
premium, if any, and interest, if any, will be payable, any terms of
redemption, any sinking fund provisions, terms for any conversion or exchange
into other securities, initial offering or purchase price, methods of
distribution and any other special terms, and (b) in the case of Preferred
Securities, the identity of the Issuer, specific title, aggregate stated
liquidation amount, number of securities, Distribution rate or method of
calculating such rate, Distribution payment dates, applicable Distribution
deferral terms, if any, place or places where Distributions will be payable,
any terms of redemption, exchange, initial offering or purchase price, methods
of distribution and any other special terms.

  The Prospectus Supplement also will contain information, as applicable,
about certain United States federal income tax consequences relating to the
Junior Subordinated Debentures or Preferred Securities.     
   
  The Junior Subordinated Debentures and Preferred Securities may be sold to
or through underwriters, through dealers, remarketing firms or agents or
directly to purchasers. See "Plan of Distribution." The names of any
underwriters, dealers, remarketing firms or agents involved in the sale of
Junior Subordinated Debentures or Preferred Securities in respect of which
this Prospectus is being delivered and any applicable fee, commission or
discount arrangements with them will be set forth in a Prospectus Supplement.
The Prospectus Supplement will state whether the Junior Subordinated
Debentures or Preferred Securities will be listed on any national securities
exchange or automated quotation system. If the Junior Subordinated Debentures
or Preferred Securities are not listed on any national securities exchange or
automated quotation system, there can be no assurance that there will be a
secondary market for the Junior Subordinated Debentures or Preferred
Securities.     
 
  This Prospectus may not be used to consummate sales of Junior Subordinated
Debentures or Preferred Securities unless accompanied by a Prospectus
Supplement.

                             AVAILABLE INFORMATION
 
  The Corporation is subject to the informational requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and in
accordance therewith, files reports, proxy statements and other information
with the Securities and Exchange Commission (the "Commission"). Such reports,
proxy statements and other information can be inspected and copied at the
public reference facilities of the Commission at Room 1024, 450 Fifth Street,
N.W., Washington, D.C. 20549 and at the regional offices of the Commission
located at 7 World Trade Center, 13th Floor, Suite 1300, New York, New York
10048 and Suite 1400, Citicorp Center, 14th Floor, 500 West Madison Street,
Chicago, Illinois 60661. Copies of such material can also be obtained at
prescribed rates by writing to the Public Reference Section of the Commission
at 450 Fifth Street, N.W., Washington, D.C. 20549. Such material may also be
accessed electronically by means of the Commission's home page on the Internet
at http://www.sec.gov. In addition, such reports, proxy statements and other
information concerning the Corporation can be inspected at the offices of the
New York Stock Exchange, Inc., 20 Broad Street, New York, New York 10005.
   
  The Corporation and the Issuers have filed with the Commission a
Registration Statement on Form S-3 (together with all amendments and exhibits
thereto, the "Registration Statement") under the Securities Act of 1933, as
amended (the "Securities Act"), with respect to the securities offered hereby.
This Prospectus does not contain all the information set forth in the
Registration Statement, certain portions of which have been omitted as
permitted by the rules and regulations of the Commission. For further
information with respect to the Corporation and the securities offered hereby,
reference is made to the Registration Statement and the exhibits and the
financial statements, notes and schedules filed as a part thereof or
incorporated by reference therein, which may be inspected at the public
reference facilities of the Commission at the addresses set forth above or
through the Commission's home page on the Internet. Statements made in this
Prospectus concerning the contents of any documents referred to herein are not
necessarily complete, and in each instance are qualified in all respects by
reference to the copy of such document filed as an exhibit to the Registration
Statement.     
   
  No separate financial statements of any Issuer have been included herein.
The Corporation and the Issuers do not consider that such financial statements
would be material to holders of the Preferred Securities because each Issuer
is a newly formed special purpose entity, has no operating history or
independent operations and is not engaged in and does not propose to engage in
any activity other than holding as trust assets the Corresponding Junior
Subordinated Debentures of the Corporation and issuing the Trust Securities.
Furthermore, taken together, the Corporation's obligations under each series
of Corresponding Junior Subordinated Debentures, the Indenture, the related
Trust Agreement, the related Expense Agreement and the related Guarantee
provide, in the aggregate, a full, irrevocable and unconditional guarantee of
payments of distributions and other amounts due on the Related Preferred
Securities of an Issuer. See "The Issuers," "Description of Preferred
Securities," "Description of Junior Subordinated Debentures--Corresponding
Junior Subordinated Debentures" and "Description of Guarantees." In addition,
the Corporation does not expect that any of the Issuers will be filing reports
under the Exchange Act with the Commission.

such Trust Securities to acquire a series of Corresponding Junior Subordinated
Debentures issued by the Corporation, and (iii) engaging in only those other
activities necessary or incidental thereto (such as registering the transfer
of the Trust Securities). Accordingly, the Corresponding Junior Subordinated
Debentures and the right to reimbursement of expenses under the related
Expense Agreement will be the sole assets of each Issuer, and payments under
the Corresponding Junior Subordinated Debentures and the related Expense
Agreement will be the sole revenue of each Issuer.     
   
  All of the Common Securities of each Issuer will be owned by the
Corporation. The Common Securities of an Issuer will rank pari passu, and
payments will be made thereon pro rata, with the Preferred Securities of such
Issuer, except that upon the occurrence and continuance of an event of default
under a Trust Agreement resulting from an event of default under the
Indenture, the rights of the Corporation as holder of the Common Securities to
payment in respect of Distributions and payments upon liquidation or
redemption will be subordinated to the rights of the holders of the Preferred
Securities of such Issuer. See "Description of Preferred Securities--
Subordination of Common Securities." The Corporation will acquire Common
Securities in an aggregate Liquidation Amount equal to not less than 3% of the
total capital of each Issuer.     
   
  Unless otherwise specified in the applicable Prospectus Supplement, each
Issuer has a term of approximately 55 years, but may terminate earlier as
provided in the applicable Trust Agreement. Each Issuer's business and affairs
are conducted by its trustees, each appointed by the Corporation as holder of
the Common Securities. The trustees for each Issuer will be The Chase
Manhattan Bank, as the Property Trustee (the "Property Trustee"), Chase
Manhattan Bank Delaware, as the Delaware Trustee (the "Delaware Trustee"), and
two individual trustees (the "Administrative Trustees") who are employees or
officers of or affiliated with the Corporation (collectively, the "Issuer
Trustees"). The Chase Manhattan Bank, as Property Trustee, will act as sole
trustee under each Trust Agreement for purposes of compliance with the Trust
Indenture Act. The Chase Manhattan Bank will also act as trustee under the
Guarantees and the Indenture. See "Description of Guarantees" and "Description
of Junior Subordinated Debentures." The holder of the Common Securities of an
Issuer, or the holders of a majority in Liquidation Amount of the Related
Preferred Securities if an event of default under the Trust Agreement for such
Issuer has occurred and is continuing, will be entitled to appoint, remove or
replace the Property Trustee and/or the Delaware Trustee for such Issuer. In
no event will the holders of the Preferred Securities have the right to vote
to appoint, remove or replace the Administrative Trustees; such voting rights
are vested exclusively in the holder of the Common Securities. The duties and
obligations of each Issuer Trustee are governed by the applicable Trust
Agreement. The Corporation will pay all fees and expenses related to each
Issuer and the offering of the Preferred Securities and will pay, directly or
indirectly, all ongoing costs, expenses and liabilities of each Issuer.     
 
  The principal executive office of each Issuer is One Mellon Bank Center, 500
Grant Street, Pittsburgh, Pennsylvania 15258, Attention: Secretary and its
telephone number is (412) 234-5000.
 
                                USE OF PROCEEDS
   
  Except as otherwise set forth in the applicable Prospectus Supplement, the
Corporation intends to use the proceeds from the sale of its Junior
Subordinated Debentures (including Corresponding Junior Subordinated
Debentures issued to the Issuers in connection with the investment by the
Issuers of all of the proceeds from the sale of Trust Securities) for general
corporate purposes, including investments in or loans to subsidiaries,
refinancing of debt, including outstanding commercial paper and other short-
term indebtedness, redemption or repurchase of shares of its outstanding
common and preferred stock, the satisfaction of other obligations or for such
other purposes as may be specified in the applicable Prospectus Supplement.

                    CERTAIN REGULATORY CONSIDERATIONS     
   
GENERAL     
   
  The Corporation (sometimes referred to herein as the "parent Corporation")
is a legal entity separate and distinct from its bank subsidiaries, although
the principal source of the parent Corporation's cash revenues are payments of
interest and dividends from such subsidiaries. There are various legal and
regulatory limitations on the extent to which the Corporation's bank
subsidiaries can finance or otherwise supply funds to the Corporation and
certain of its other affiliates.     
   
  The prior approval of the Comptroller of the Currency (the "Comptroller") is
required if the total of all dividends declared by any such national bank
subsidiary in any calendar year exceeds its net profits (as defined by the
Comptroller) for that year combined with its retained net profits for the
preceding two calendar years. Additionally, national bank subsidiaries may not
declare dividends in excess of net profits on hand (as defined), after
deducting the amount by which the principal amount of all loans on which
interest is past due for a period of six months or more exceeds the reserve
for credit losses. Under the first and currently more restrictive of the
foregoing dividend limitations, the Corporation's national bank subsidiaries
can, without prior regulatory approval, declare dividends for the remainder of
1996, subsequent to September 30, 1996 of up to approximately $317 million of
their retained earnings of approximately $2.264 billion at September 30, 1996,
less any dividends declared and plus or minus net profits or losses, as
defined, between October 1, 1996, and the date of any such dividend
declaration. The payment of dividends is also limited by minimum capital
requirements imposed on all national bank subsidiaries by the Comptroller. The
capital of the Corporation's national bank subsidiaries exceed these minimum
requirements. The national bank subsidiaries declared dividends to the parent
Corporation of $300 million in the first nine months of 1996, $501 million in
1995, $366 million in 1994 and $185 million in 1993. Dividends paid to the
parent Corporation by nonbank subsidiaries totaled $16 million in the first
nine months of 1996, $30 million in 1995, $122 million in 1994 and $116
million in 1993. In addition, Mellon Bank, N.A. returned $200 million and $300
million of capital to the parent Corporation in the first nine months of 1996
and full year 1995, respectively, and The Boston Company returned $150 million
of capital to the parent Corporation in the first nine months of 1996 and $100
million and $300 million in 1994 and 1993, respectively.     
   
  The Federal Reserve Board and the Comptroller also have issued guidelines
that require bank holding companies and national banks to continuously
evaluate the level of cash dividends in relation to the organization's
operating income, capital needs, asset quality and overall financial
condition. The Comptroller also has authority under the Financial Institutions
Supervisory Act to prohibit national banks from engaging in any activity
which, in the Comptroller's opinion, constitutes an unsafe or unsound practice
in conducting their businesses. The payment of a dividend by a bank could,
depending upon the financial condition of such bank and other factors, be
construed by the Comptroller to be such an unsafe or unsound practice. The
Comptroller has stated that a dividend by a national bank should bear a direct
correlation to the level of the bank's current and expected earnings stream,
the bank's need to maintain an adequate capital base and the marketplace's
perception of the bank and should not be governed by the financing needs of
the bank's parent corporation. If the ability of such subsidiaries to pay
dividends to the Corporation were to become restricted, the Corporation would
need to rely on alternative means of raising funds to satisfy its cash
requirements, which might include, but would not be restricted to, nonbank
subsidiary dividends, asset sales or other capital market transactions.     
   
  The Financial Institutions Reform, Recovery and Enforcement Act of 1989
contains a "cross-guarantee" provision that could result in any insured
depository institution owned by the Corporation (i.e., any bank subsidiary)
being assessed for losses incurred by the Federal Deposit Insurance
Corporation (the "FDIC") in connection with assistance provided to, or the
failure of, any other depository institution owned by the Corporation. Under
Federal Reserve Board policy, the Corporation     
 
                                       7
<PAGE>
 
   
may be expected to act as a source of financial strength to each of its bank
subsidiaries and to commit resources to support each such bank in
circumstances where such bank might not be in a financial position to do so.
       
FDICIA     
   
  The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
substantially revised the bank regulatory and funding provisions of the
Federal Deposit Insurance Act and made revisions to several other federal
banking statutes. Among other things, FDICIA requires the federal banking
agencies to take "prompt corrective action" in respect of depository
institutions that do not meet minimum capital requirements. FDICIA establishes
five capital tiers: "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" and "critically
undercapitalized."     
   
  Rules adopted by the federal banking agencies under FDICIA provide that an
institution is deemed to be: "well capitalized" if the institution has a total
(Tier I plus Tier II) risk-based capital ratio of 10.0% or greater, a Tier I
risk-based ratio of 6.0% or greater, and a leverage ratio of 5.0% or greater,
and the institution is not subject to an order, written agreement, capital
directive or prompt corrective action directive to meet and maintain a
specific level for any capital measure; "adequately capitalized" if the
institution has a total risk-based capital ratio of 8.0% or greater, a Tier I
risk-based capital ratio of 4.0% or greater, and a leverage ratio of 4.0% or
greater (or a leverage ratio of 3.0% or greater if the institution is rated
composite 1 in its most recent report of examination, subject to appropriate
federal banking agency guidelines), and the institution does not meet the
definition of a well-capitalized institution; "undercapitalized" if the
institution has a total risk-based capital ratio that is less than 8.0%, a
Tier I risk-based capital ratio that is less than 4.0% or a leverage ratio
that is less than 4.0% (or a leverage ratio that is less than 3.0% if the
institution is rated composite 1 in its most recent report of examination,
subject to appropriate federal banking agency guidelines) and the institution
does not meet the definition of a significantly undercapitalized or critically
undercapitalized institution; "significantly undercapitalized" if the
institution has a total risk-based capital ratio that is less than 6.0%, a
Tier I risk-based capital ratio that is less than 3.0%, or a leverage ratio
that is less than 3.0% and the institution does not meet the definition of a
critically undercapitalized institution; and "critically undercapitalized" if
the institution has a ratio of tangible equity to total assets that is equal
to or less than 2.0%. FDICIA imposes progressively more restrictive
constraints on operations, management and capital distributions, depending on
the capital category in which an institution is classified.     
   
  At September 30, 1996, all of the Corporation's banking subsidiaries
qualified as well capitalized based on the ratios and guidelines noted above.
A bank's capital category, however, is determined solely for the purpose of
applying the prompt corrective action rules and may not constitute an accurate
representation of the bank's overall financial condition or prospects.     
   
  The appropriate federal banking agency may, under certain circumstances,
reclassify a well capitalized insured depository institution as adequately
capitalized. The appropriate agency is also permitted to require an adequately
capitalized or undercapitalized institution to comply with the supervisory
provisions as if the institution were in the next lower category (but not
treat a significantly undercapitalized institution as critically
undercapitalized) based on supervisory information other than the capital
levels of the institution.     
   
  The statute provides that an institution may be reclassified if the
appropriate federal banking agency determines (after notice and opportunity
for hearing) that the institution is in an unsafe or unsound condition or
deems the institution to be engaging in an unsafe or unsound practice.     
   
  FDICIA generally prohibits a depository institution from making any capital
distribution (including payment of a dividend) or paying any management fee to
its holding company if the depository     
 
                                       8
<PAGE>
 
   
institution would thereafter be undercapitalized. Undercapitalized depository
institutions are subject to growth limitations and are required to submit a
capital restoration plan. The federal banking agencies may not accept a
capital restoration plan without determining, among other things, that the
plan is based on realistic assumptions and is likely to succeed in restoring
the depository institution's capital.
       
In addition, for a capital restoration plan to be acceptable, the depository
institution's parent holding company must guarantee that the institution will
comply with such capital restoration plan. T~he aggregate liability of the
parent holding company is limited to the lesser of (i) an amount equal to 5.0%
of the depository institution's total assets at the time it became
undercapitalized, and (ii) the amount which is necessary (or would have been
necessary) to bring the institution into compliance with all capital standards
applicable with respect to such institution as of the time it fails to comply
with the plan. If a depository institution fails to submit an acceptable plan,
it is treated as if it is significantly undercapitalized.     
   
  Significantly undercapitalized depository institutions may be subject to a
number of requirements and restrictions, including orders to sell sufficient
voting stock to become adequately capitalized, requirements to reduce total
assets and cessation of receipt of deposits from correspondent banks.
Critically undercapitalized institutions are subject to the appointment of a
receiver or conservator.     
   
  FDICIA also contains a variety of other provisions that may affect the
operation of the Corporation, and its subsidiaries and affiliates, including
new reporting requirements, regulatory standards for real estate lending,
"truth in savings" provisions, and the requirement that a depository
institution give 90 days prior notice to customers and regulatory authorities
before closing any branch.     
   
CAPITAL     
   
  The risk-based capital guidelines for bank holding companies and banks
adopted by the federal banking agencies were fully phased in at the end of
1992. The minimum ratio of qualifying total capital to risk-weighted assets
(including certain off-balance sheet items, such as standby letters of credit)
under the fully phased in guidelines is 8.0%. At least half of the total
capital is to be comprised of common stock, retained earnings, noncumulative
perpetual preferred stock, minority interests and, for bank holding companies,
a limited amount of qualifying cumulative perpetual preferred stock, less
goodwill and certain other intangibles ("Tier I capital"). The remainder
("Tier II capital") may consist of other preferred stock, certain other
instruments, and limited amounts of subordinated debt and the reserve for
credit losses.     
   
  In addition, the federal banking agencies have established minimum leverage
ratio (Tier I capital to total average assets less goodwill and certain other
intangibles) guidelines for bank holding companies and banks. These guidelines
provide for a minimum leverage ratio of 3.0% for bank holding companies and
banks that meet certain specified criteria, including that they have the
highest regulatory rating. All other banking organizations are required to
maintain a leverage ratio of 3.0% plus an additional cushion of at least 100
to 200 basis points. The guidelines also provide that banking organizations
experiencing internal growth or making acquisitions will be expected to
maintain strong capital positions substantially above the minimum supervisory
levels, without significant reliance on intangible assets. Furthermore, the
guidelines indicate that the Federal Reserve Board will continue to consider a
"tangible Tier I leverage ratio" in evaluating proposals for expansion or new
activities. The tangible Tier I leverage ratio is the ratio of Tier I capital,
less intangibles not deducted from Tier I capital, to total assets, less all
intangibles. Neither the Corporation nor any of its banking subsidiaries has
been advised of any specific minimum leverage ratio applicable to it.     
   
  The federal banking agencies have revised their risk-based capital standards
to ensure that such standards take adequate account of concentrations of
credit risk and the risks of nontraditional activities. Institutions with high
or moderate levels of risks are expected to operate above minimum capital
standards.     
 
                                       9
<PAGE>
 
          
  In November 1994, the federal banking agencies announced that they
determined not to amend regulatory capital regulations to incorporate the
change in generally accepted accounting principles made by Statement of
Financial Accounting Standards No. 115, which requires that unrealized gains
and losses, net of the related tax effect, on securities classified as
available for sale be reported as a separate component of stockholders'
equity.     
   
  The federal banking agencies have adopted rules to incorporate market and
interest rate risk components into their risk-based capital standards.     
   
  Certain consolidated ratios of the Corporation are included herein under
"Mellon Bank Corporation--Consolidated Summary Financial Data."     
   
FDIC INSURANCE ASSESSMENTS; DIFA     
   
  The FDIC significantly reduced the insurance premiums it charges on bank
deposits insured by the Bank Insurance Fund ("BIF") to the statutory minimum
of $2,000.00 annually for "well capitalized" banks, effective January 1, 1996.
Premiums related to savings association deposits acquired by banks continued
to be assessed at the rate of 23 cents to 31 cents per $100.00 of deposits. On
September 30, 1996, the Deposit Insurance Funds Act of 1996 ("DIFA") was
enacted and signed into law. DIFA is expected to reduce the amount of semi-
annual FDIC insurance premiums for savings association deposits acquired by
banks to the same levels assessed for deposits insured by BIF.     
   
  DIFA also provides for a special one-time assessment imposed on deposits
insured by the Savings Association Insurance Fund ("SAIF"), including such
deposits held by banks, to recapitalize the SAIF to bring the SAIF up to
statutory required levels. The Corporation's one time assessment, was minimal.
       
  DIFA further provides for assessments to be imposed on insured depository
institutions with respect to deposits insured by the BIF (in addition to
assessments currently imposed on depository institutions with respect to SAIF-
insured deposits) to pay for the cost of Financing Corporation funding. Based
on September 30, 1996 deposit levels, the Corporation currently estimates
assessments will amount to approximately $3 million pre-tax in 1997.     
   
INTERSTATE BANKING AND BRANCHING LEGISLATION     
   
  On September 29, 1994, the Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 (the "Interstate Act") was enacted into Federal law.
Under the Interstate Act, commencing on September 29, 1995, bank holding
companies are permitted to acquire banks located in any state regardless of
the state law in effect at the time. The Interstate Act also provides for the
nationwide interstate branching of banks. Under the Interstate Act, both
national and state-chartered banks will be permitted to merge across state
lines (and thereby create interstate branches) commencing June 1, 1997. States
are permitted to "opt-out" of the interstate branching authority by taking
action prior to the commencement date. States may also "opt-in" early (i.e.,
prior to June 1, 1997) to the interstate branching provisions. Pennsylvania
has chosen to "opt-in" early, effective July 6, 1995, thereby enabling
Pennsylvania banks, including national banks having their main office in
Pennsylvania, to merge with out-of-state banks to create interstate branches
inside or outside Pennsylvania. In addition, Pennsylvania has permitted de
novo branching into and out of Pennsylvania as long as the law of the other
state involved is reciprocal in this regard.

                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES
   
  The Junior Subordinated Debentures are to be issued in one or more series
under a Junior Subordinated Indenture, as supplemented from time to time (as
so supplemented, the "Indenture"), between the Corporation and The Chase
Manhattan Bank, as trustee (the "Debenture Trustee"). This summary of certain
terms and provisions of the Junior Subordinated Debentures, Corresponding
Junior Subordinated Debentures and the Indenture, which summarizes the
material provisions thereof, does not purport to be complete and is subject
to, and is qualified in its entirety by reference to, the Indenture, the form
of which is filed as an exhibit to the Registration Statement of which this
Prospectus forms a part, and to the Trust Indenture Act, to each of which
reference is hereby made. The Indenture is qualified under the Trust Indenture
Act. Whenever particular defined terms of the Indenture (as supplemented or
amended from time to time) are referred to herein or in a Prospectus
Supplement, such defined terms are incorporated herein or therein by
reference.     
 
GENERAL
   
  Each series of Junior Subordinated Debentures will rank pari passu with all
other series of Junior Subordinated Debentures and will be unsecured and
subordinate and junior in right of payment to the extent and in the manner set
forth in the Indenture to all Senior Debt (as defined below) of the
Corporation. See "--Subordination". Because the Corporation is a holding
company, the right of the Corporation to participate in any distribution of
assets of any subsidiary upon such subsidiary's liquidation or reorganization
or otherwise, is subject to the prior claims of creditors of the subsidiary,
except to the extent the Corporation may itself be recognized as a creditor of
that subsidiary. Accordingly, the Junior Subordinated Debentures will be
effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and holders of Junior Subordinated Debentures
should look only to the assets of the Corporation for payments on the Junior
Subordinated Debentures. Except as otherwise provided in the applicable
Prospectus Supplement, the Indenture does not limit the incurrence or issuance
of other secured or unsecured debt of the Corporation, including Senior Debt,
whether under the Indenture, any other existing indenture or any other
indenture that the Corporation may enter into in the future or otherwise. See
"--Subordination" and the applicable Prospectus Supplement relating to any
offering of Preferred Securities or Junior Subordinated Debentures.     
 
  The Junior Subordinated Debentures will be issuable in one or more series
pursuant to an indenture supplemental to the Indenture or a resolution of the
Corporation's Board of Directors or a committee thereof.
   
  The applicable Prospectus Supplement will describe the following terms of
the Junior Subordinated Debentures: (1) the title of the Junior Subordinated
Debentures; (2) any limit upon the aggregate principal amount of the Junior
Subordinated Debentures; (3) the date or dates on which the principal of the
Junior Subordinated Debentures is payable (the "Stated Maturity") or the
method of determination thereof; (4) the rate or rates, if any, at which the
Junior Subordinated Debentures shall bear interest, the dates on which any
such interest shall be payable (the "Interest Payment Dates"), the right, if
any, of the Corporation to defer or extend an Interest Payment Date, and the
record dates for any interest payable on any Interest Payment Date (the
"Regular Record Dates") or the method by which any of the foregoing shall be
determined; (5) the place or places where, subject to the terms of the
Indenture as described below under "--Payment and Paying Agents", the
principal of and premium, if any, and interest on the Junior Subordinated
Debentures will be payable and where, subject to the terms of the Indenture as
described below under "--Denominations, Registration and Transfer," the Junior
Subordinated Debentures may be presented for registration of transfer or
exchange and the place or places where notices and demands to or upon the
Corporation in respect of the Junior Subordinated Debentures and the
Indentures may be made ("Place of Payment"); (6) any period or periods within
which, or date or dates on which, the price or prices at which and the terms
    
                                      11
<PAGE>
 
   
and conditions upon which Junior Subordinated Debentures may be redeemed, in
whole or in part, at the option of the Corporation or a holder thereof; (7)
the obligation or the right, if any, of the Corporation or a holder thereof to
redeem, purchase or repay the Junior Subordinated Debentures and the period or
periods within which, the price or prices at which, the currency or currencies
(including currency unit or units) in which and the other terms and conditions
upon which the Junior Subordinated Debentures shall be redeemed, repaid or
purchased, in whole or in part, pursuant to such obligation; (8) the
denominations in which any Junior Subordinated Debentures shall be issuable if
other than denominations of $25 and any integral multiple thereof; (9) if
other than in U.S. Dollars, the currency or currencies (including currency
unit or units) in which the principal of (and premium, if any) and interest,
if any, on the Junior Subordinated Debentures shall be payable, or in which
the Junior Subordinated Debentures shall be denominated; (10) any additions,
modifications or deletions in the events of default under the Indenture or
covenants of the Corporation specified in the Indenture with respect to the
Junior Subordinated Debentures; (11) if other than the principal amount
thereof, the portion of the principal amount of Junior Subordinated Debentures
that shall be payable upon declaration of acceleration of the maturity
thereof; (12) any additions or changes to the Indenture with respect to a
series of Junior Subordinated Debentures as shall be necessary to permit or
facilitate the issuance of such series in bearer form, registrable or not
registrable as to principal, and with or without interest coupons; (13) any
index or indices used to determine the amount of payments of principal of and
premium, if any, on the Junior Subordinated Debentures and the manner in which
such amounts will be determined; (14) the terms and conditions relating to the
issuance of a temporary Global Security representing all of the Junior
Subordinated Debentures of such series and the exchange of such temporary
Global Security for definitive Junior Subordinated Debentures of such series;
(15) subject to the terms described herein under "--Global Junior Subordinated
Debentures", whether the Junior Subordinated Debentures of the series shall be
issued in whole or in part in the form of one or more Global Securities and,
in such case, the depositary for such Global Securities, which depositary
shall be a clearing agency registered under the Exchange Act; (16) the
appointment of any paying agent or agents; (17) the terms and conditions of
any obligation or right of the Corporation or a holder to convert or exchange
the Junior Subordinated Debentures into Preferred Securities; (18) the form of
Trust Agreement, Guarantee Agreement and Expense Agreement, if applicable;
(19) the relative degree, if any, to which such Junior Subordinated Debentures
of the series shall be senior to or be subordinated to other series of such
Junior Subordinated Debentures or other indebtedness of the Corporation in
right of payment, whether such other series of Junior Subordinated Debentures
or other indebtedness are outstanding or not; and (20) any other terms of the
Junior Subordinated Debentures not inconsistent with the provisions of the
Indenture.     
   
  Junior Subordinated Debentures may be sold at a substantial discount below
their stated principal amount, bearing no interest or interest at a rate which
at the time of issuance is below market rates. Certain United States federal
income tax consequences and special considerations applicable to any such
Junior Subordinated Debentures will be described in the applicable Prospectus
Supplement.     
   
  If the purchase price of any of the Junior Subordinated Debentures is
payable in one or more foreign currencies or currency units or if any Junior
Subordinated Debentures are denominated in one or more foreign currencies or
currency units or if the principal of, premium, if any, or interest on any
Junior Subordinated Debentures is payable in one or more foreign currencies or
currency units, the restrictions, elections, certain United States federal
income tax consequences, specific terms and other information with respect to
such series of Junior Subordinated Debentures and such foreign currency or
currency units will be set forth in the applicable Prospectus Supplement.     
   
  If any index is used to determine the amount of payments of principal of,
premium, if any, or interest on any series of Junior Subordinated Debentures,
special United States federal income tax, accounting and other considerations
applicable thereto will be described in the applicable Prospectus Supplement.
    
                                      12

DENOMINATIONS, REGISTRATION AND TRANSFER
   
  Unless otherwise specified in the applicable Prospectus Supplement, the
Junior Subordinated Debentures will be issuable only in registered form
without coupons in denominations of $25 and any integral multiple thereof.
Junior Subordinated Debentures of any series will be exchangeable for other
Junior Subordinated Debentures of the same issue and series, of any authorized
denominations, of a like aggregate principal amount, of the same original
issue date and stated maturity and bearing the same interest rate.     
   
  Junior Subordinated Debentures may be presented for exchange as provided
above, and may be presented for registration of transfer (with the form of
transfer endorsed thereon, or a satisfactory written instrument of transfer,
duly executed), at the office of the appropriate securities registrar or at
the office of any transfer agent designated by the Corporation for such
purpose with respect to any series of Junior Subordinated Debentures and
referred to in the applicable Prospectus Supplement, without service charge
and upon payment of any taxes and other governmental charges as described in
the Indenture. The Corporation will appoint the Trustee as securities
registrar under the Indenture. If the applicable Prospectus Supplement refers
to any transfer agents (in addition to the securities registrar) initially
designated by the Corporation with respect to any series of Junior
Subordinated Debentures, the Corporation may at any time rescind the
designation of any such transfer agent or approve a change in the location
through which any such transfer agent acts, provided that the Corporation
maintains a transfer agent in each place of payment for such series. The
Corporation may at any time designate additional transfer agents with respect
to any series of Junior Subordinated Debentures.     
 
  In the event of any redemption, neither the Corporation nor the Debenture
Trustee shall be required to (i) issue, register the transfer of or exchange
Junior Subordinated Debentures of any series during a period beginning at the
opening of business 15 days before the day of selection for redemption of
Junior Subordinated Debentures of that series and ending at the close of
business on the day of mailing of the relevant notice of redemption or (ii)
transfer or exchange any Junior Subordinated Debentures so selected for
redemption, except, in the case of any Junior Subordinated Debentures being
redeemed in part, any portion thereof not to be redeemed.
 
GLOBAL JUNIOR SUBORDINATED DEBENTURES
 
  The Junior Subordinated Debentures of a series may be issued in whole or in
part in the form of one or more Global Junior Subordinated Debentures that
will be deposited with, or on behalf of, a depositary (the "Depositary")
identified in the Prospectus Supplement relating to such series. Global Junior
Subordinated Debentures may be issued only in fully registered form and in
either temporary or permanent form. Unless and until it is exchanged in whole
or in part for the individual Junior Subordinated Debentures represented
thereby, a Global Junior Subordinated Debenture may not be transferred except
as a whole by the Depositary for such Global Junior Subordinated Debenture to
a nominee of such Depositary or by a nominee of such Depositary to such
Depositary or another nominee of such Depositary or by the Depositary or any
nominee to a successor Depositary or any nominee of such successor.
 
  The specific terms of the depositary arrangement with respect to a series of
Junior Subordinated Debentures will be described in the Prospectus Supplement
relating to such series. The Corporation anticipates that the following
provisions will generally apply to depositary arrangements.
 
  Upon the issuance of a Global Junior Subordinated Debenture, and the deposit
of such Global Junior Subordinated Debenture with or on behalf of the
Depositary, the Depositary for such Global Junior Subordinated Debenture or
its nominee will credit, on its book-entry registration and transfer system,
the respective principal amounts of the individual Junior Subordinated
Debentures represented
 
                                      13
<PAGE>
 
by such Global Junior Subordinated Debenture to the accounts of persons that
have accounts with such Depositary ("Participants"). Such accounts shall be
designated by the dealers, underwriters or agents with respect to such Junior
Subordinated Debentures or by the Corporation if such Junior Subordinated
Debentures are offered and sold directly by the Corporation. Ownership of
beneficial interests in a Global Junior Subordinated Debenture will be limited
to Participants or persons that may hold interests through Participants.
Ownership of beneficial interests in such Global Junior Subordinated Debenture
will be shown on, and the transfer of that ownership will be effected only
through, records maintained by the applicable Depositary or its nominee (with
respect to interests of Participants) and the records of Participants (with
respect to interests of persons who hold through Participants). The laws of
some states require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Junior
Subordinated Debenture.
 
  So long as the Depositary for a Global Junior Subordinated Debenture, or its
nominee, is the registered owner of such Global Junior Subordinated Debenture,
such Depositary or such nominee, as the case may be, will be considered the
sole owner or holder of the Junior Subordinated Debentures represented by such
Global Junior Subordinated Debenture for all purposes under the Indenture
governing such Junior Subordinated Debentures. Except as provided below,
owners of beneficial interests in a Global Junior Subordinated Debenture will
not be entitled to have any of the individual Junior Subordinated Debentures
of the series represented by such Global Junior Subordinated Debenture
registered in their names, will not receive or be entitled to receive physical
delivery of any such Junior Subordinated Debentures of such series in
definitive form and will not be considered the owners or holders thereof under
the Indenture.
 
  Payments of principal of (and premium, if any) and interest on individual
Junior Subordinated Debentures represented by a Global Junior Subordinated
Debenture registered in the name of a Depositary or its nominee will be made
to the Depositary or its nominee, as the case may be, as the registered owner
of the Global Junior Subordinated Debenture representing such Junior
Subordinated Debentures. None of the Corporation, the Debenture Trustee, any
Paying Agent, or the Securities Registrar for such Junior Subordinated
Debentures will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of the Global Junior Subordinated Debenture representing such Junior
Subordinated Debentures or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
   
  The Corporation expects that the Depositary for a series of Junior
Subordinated Debentures or its nominee, upon receipt of any payment of
principal, premium, if any, or interest in respect of a permanent Global
Junior Subordinated Debenture representing any of such Junior Subordinated
Debentures, immediately will credit Participants' accounts with payments in
amounts proportionate to their respective beneficial interest in the principal
amount of such Global Junior Subordinated Debenture for such Junior
Subordinated Debentures as shown on the records of such Depositary or its
nominee. The Corporation also expects that payments by Participants to owners
of beneficial interests in such Global Junior Subordinated Debenture held
through such Participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts
of customers in bearer form or registered in "street name." Such payments will
be the responsibility of such Participants.     
 
  Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for a series of Junior Subordinated Debentures is at any time
unwilling, unable or ineligible to continue as depositary and a successor
depositary is not appointed by the Corporation within 90 days, the Corporation
will issue individual Junior Subordinated Debentures of such series in
exchange for the Global Junior Subordinated Debenture representing such series
of Junior Subordinated Debentures. In addition, the Corporation may at any
time and in its sole discretion, subject to any limitations described in the
Prospectus Supplement relating to such Junior Subordinated Debentures,
determine
 
                                      14
<PAGE>
 
   
not to have any Junior Subordinated Debentures of such series represented by
one or more Global Junior Subordinated Debentures and, in such event, will
issue certificated Junior Subordinated Debentures of such series in exchange
for the Global Junior Subordinated Debenture. Further, if the Corporation so
specifies with respect to the Junior Subordinated Debentures of a series, an
owner of a beneficial interest in a Global Junior Subordinated Debenture
representing Junior Subordinated Debentures of such series may, on terms
acceptable to the Corporation, the Debenture Trustee and the Depositary for
such Global Junior Subordinated Debenture, receive certificated Junior
Subordinated Debentures of such series in exchange for such beneficial
interests, subject to any limitations described in the Prospectus Supplement
relating to such Junior Subordinated Debentures. In any such instance, an
owner of a beneficial interest in a Global Junior Subordinated Debenture will
be entitled to physical delivery of certificated Junior Subordinated
Debentures of the series represented by such Global Junior Subordinated
Debenture equal in principal amount to such beneficial interest and to have
such Junior Subordinated Debentures registered in its name. Individual Junior
Subordinated Debentures of such series so issued will be issued in
denominations, unless otherwise specified by the Corporation, of $25 and
integral multiples thereof.     
 
PAYMENT AND PAYING AGENTS
   
  Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of (and premium, if any) and any interest on Junior Subordinated
Debentures will be made at the office of the Debenture Trustee in the City of
New York or at the office of such paying agent or paying agents as the
Corporation may designate from time to time in the applicable Prospectus
Supplement, except that at the option of the Corporation payment of any
interest may be made (i) except in the case of Global Junior Subordinated
Debentures, by check mailed to the address of the person entitled thereto as
such address shall appear in the securities register or (ii) by transfer to an
account maintained by the person entitled thereto as specified in the
securities register, provided that proper transfer instructions have been
received by the Regular Record Date. Unless otherwise indicated in the
applicable Prospectus Supplement, payment of any interest on Junior
Subordinated Debentures will be made to the person in whose name such Junior
Subordinated Debenture is registered at the close of business on the Regular
Record Date for such interest, except in the case of defaulted interest. The
Corporation may at any time designate additional paying agents or rescind the
designation of any paying agent; however the Corporation will at all times be
required to maintain a paying agent in each place of payment for each series
of Junior Subordinated Debentures.     
   
  Any moneys deposited with the Debenture Trustee or any paying agent, or then
held by the Corporation in trust, for the payment of the principal of (and
premium, if any) or interest on any Junior Subordinated Debenture and
remaining unclaimed for two years after such principal (and premium, if any)
or interest has become due and payable shall, at the request of the
Corporation, be repaid to the Corporation and the holder of such Junior
Subordinated Debenture shall thereafter look, as a general unsecured creditor,
only to the Corporation for payment thereof.     
   
OPTION TO DEFER INTEREST PAYMENTS     
   
  If provided in the applicable Prospectus Supplement, the Corporation will
have the right at any time and from time to time during the term of any series
of Junior Subordinated Debentures to defer payment of interest for up to such
number of consecutive interest payment periods as may be specified in the
applicable Prospectus Supplement (each, an "Extension Period"), subject to the
terms, conditions and covenants, if any, specified in such Prospectus
Supplement, provided that such Extension Period may not extend beyond the
Stated Maturity of such series of Junior Subordinated Debentures. Certain
United States federal income tax consequences and special considerations
applicable to any such Junior Subordinated Debentures will be described in the
applicable Prospectus Supplement.     
 
 
                                      15

REDEMPTION
 
  Unless otherwise indicated in the applicable Prospectus Supplement, Junior
Subordinated Debentures will not be subject to any sinking fund.
   
  Unless otherwise indicated in the applicable Prospectus Supplement, the
Corporation may, at its option and subject to receipt of prior approval by the
Board of Governors of the Federal Reserve System (the "Federal Reserve") if
then required under applicable capital guidelines or policies, redeem the
Junior Subordinated Debentures of any series in whole at any time or in part
from time to time. If the Junior Subordinated Debentures of any series are so
redeemable only on or after a specified date or upon the satisfaction of
additional conditions, the applicable Prospectus Supplement will specify such
date or describe such conditions. Junior Subordinated Debentures in
denominations larger than $25 may be redeemed in part but only in integral
multiples of $25. Except as otherwise specified in the applicable Prospectus
Supplement, the redemption price for any Junior Subordinated Debenture so
redeemed shall equal any accrued and unpaid interest thereon to the redemption
date, plus 100% of the principal amount thereof.     
   
  Except as otherwise specified in the applicable Prospectus Supplement, if a
Debenture Tax Event (as defined below) in respect of a series of Junior
Subordinated Debentures or a Capital Treatment Event (as defined herein) shall
occur and be continuing, the Corporation may, at its option and subject to
receipt of prior approval by the Federal Reserve if then required under
applicable capital guidelines or policies, redeem such series of Junior
Subordinated Debentures in whole (but not in part) at any time within 90 days
following the occurrence of such Debenture Tax Event or Capital Treatment
Event at a redemption price equal to 100% of the principal amount of such
Junior Subordinated Debentures then outstanding plus accrued and unpaid
interest to the date fixed for redemption, except as otherwise specified in
the applicable Prospectus Supplement.     
   
  "Debenture Tax Event" means the receipt by the Corporation of an opinion of
counsel experienced in such matters to the effect that, as a result of any
amendment to, or change (including any announced proposed change) in, the laws
(or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
which proposed change, pronouncement or decision is announced on or after the
date of issuance of the applicable series of Junior Subordinated Debentures
under the Indenture, there is more than an insubstantial risk that interest
payable by the Corporation on such series of Junior Subordinated Debentures is
not, or within 90 days of the date of such opinion will not be, deductible by
the Corporation, in whole or in part, for United States federal income tax
purposes.     
   
  A "Capital Treatment Event" means the reasonable determination by the
Corporation that, as a result of any amendment to, or change (including any
proposed change) in, the laws (or any regulations thereunder) of the United
States or any political subdivision thereof or therein, or as a result of any
official or administrative pronouncement or action or judicial decision
interpreting or applying such laws or regulations, which amendment or change
is effective or such proposed change, pronouncement or decision is announced
on or after the date of issuance of the applicable Preferred Securities under
the applicable Trust Agreement, there is more than an insubstantial risk that
the Corporation will not be entitled to treat an amount equal to the
Liquidation Amount of the applicable Preferred Securities as "Tier 1 Capital"
(or the then equivalent thereof) for purposes of the capital adequacy
guidelines of the Federal Reserve, as then in effect and applicable to the
Corporation.     
   
  Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Junior Subordinated
Debentures to be redeemed at its registered address. Unless the Corporation
defaults in payment of the redemption price, on and after the redemption date
interest ceases to accrue on such Junior Subordinated Debentures or portions
thereof called for redemption.     
 
                                      16

RESTRICTIONS ON CERTAIN PAYMENTS
   
  The Corporation will also covenant, as to each series of Junior Subordinated
Debentures, that it will not, and will not permit any subsidiary of the
Corporation to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any
of the Corporation's capital stock, (ii) make any payment of principal,
interest or premium, if any, on or repay or repurchase or redeem any debt
securities of the Corporation (including other series of Junior Subordinated
Debentures) that rank pari passu with or junior in interest to the Junior
Subordinated Debentures or (iii) make any guarantee payments with respect to
any guarantee by the Corporation of the debt securities of any subsidiary of
the Corporation if such guarantee ranks pari passu with or junior in interest
to the Junior Subordinated Debentures (other than (a) dividends or
distributions in capital stock of the Corporation, (b) any declaration of a
dividend in connection with the implementation of a stockholders' rights plan,
or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under any Guarantee with respect to the series of Related Preferred
Securities and (d) purchases of common stock related to the issuance of common
stock or rights under any of the Corporation's benefit plans for its
directors, officers or employees, related to the issuance of common stock or
rights under a dividend reinvestment and stock purchase plan, or related to
the issuance of common stock (or securities convertible into or exchangeable
for common stock) as consideration in an acquisition transaction) if at such
time (i) there shall have occurred any event of which the Corporation has
actual knowledge (a) that with the giving of notice or the lapse of time, or
both, would constitute an "Event of Default" under the Indenture with respect
to the Junior Subordinated Debentures of such series and (b) in respect of
which the Corporation shall not have taken reasonable steps to cure, (ii) if
such Junior Subordinated Debentures are held by an Issuer of a series of
Related Preferred Securities, the Corporation shall be in default with respect
to its payment of any obligations under the Guarantee relating to such Related
Preferred Securities or (iii) the Corporation shall have given notice of its
selection of an Extension Period as provided in the Indenture with respect to
the Junior Subordinated Debentures of such series and shall not have rescinded
such notice, or such Extension Period, or any extension thereof, shall be
continuing.     
 
MODIFICATION OF INDENTURE
   
  From time to time the Corporation and the Debenture Trustee may, without the
consent of the holders of any series of Junior Subordinated Debentures, amend,
waive or supplement the Indenture for specified purposes, including, among
other things, curing ambiguities, defects or inconsistencies (provided that
any such action does not materially adversely affect the interest of the
holders of any series of Junior Subordinated Debentures or, in the case of
Corresponding Junior Subordinated Debentures, the holders of the Related
Preferred Securities so long as they remain outstanding) and qualifying, or
maintaining the qualification of, the Indenture under the Trust Indenture Act.
The Indenture contains provisions permitting the Corporation and the Debenture
Trustee, with the consent of the holders of not less than a majority in
principal amount of each outstanding series of Junior Subordinated Debentures
affected, to modify the Indenture in a manner adversely affecting the rights
of the holders of such series of the Junior Subordinated Debentures in any
material respect; provided, that no such modification may, without the consent
of the holder of each outstanding Junior Subordinated Debenture so affected,
(i) change the Stated Maturity of any series of Junior Subordinated Debentures
(except as otherwise specified in the applicable Prospectus Supplement), or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon or (ii) reduce the percentage of principal amount
of Junior Subordinated Debentures of any series, the holders of which are
required to consent to any such modification of the Indenture, provided
further that, in the case of Corresponding Junior Subordinated Debentures, so
long as any Related Preferred Securities remain outstanding, (a) no such
modification may be made that adversely affects the holders of such Preferred
Securities in any material respect, and no termination of the Indenture may
occur, and no waiver of any event of default or compliance with any covenant
under the Indenture may be effective, without the prior consent of the holders
of at least a majority of the aggregate     
 
                                      17
<PAGE>
 
   
Liquidation Amount of all outstanding Related Preferred Securities affected
unless and until the principal of the Corresponding Junior Subordinated
Debentures and all accrued and unpaid interest thereon have been paid in full
and certain other conditions have been satisfied, and (b) where a consent
under the Indenture would require the consent of each holder of Corresponding
Junior Subordinated Debentures, no such consent shall be given by the Property
Trustee without the prior consent of each holder of Related Preferred
Securities.     
 
  In addition, the Corporation and the Debenture Trustee may execute, without
the consent of any holder of Junior Subordinated Debentures, any supplemental
Indenture for the purpose of creating any new series of Junior Subordinated
Debentures.
 
DEBENTURE EVENTS OF DEFAULT
 
  The Indenture provides that any one or more of the following described
events with respect to a series of Junior Subordinated Debentures that has
occurred and is continuing constitutes a "Debenture Event of Default" with
respect to such series of Junior Subordinated Debentures:
   
  (i)  failure for 30 days to pay any interest on such series of Junior
       Subordinated Debentures when due (subject to the deferral of any
       interest payment in the case of an Extension Period); or     
   
  (ii) failure to pay any principal or premium, if any, on such series of
       Junior Subordinated Debentures when due whether at maturity or upon
       redemption; or     
   
  (iii) failure to observe or perform in any material respect certain other
        covenants contained in the Indenture for 90 days after written notice
        to the Corporation from the Debenture Trustee or the holders of at
        least 25% in aggregate outstanding principal amount of such affected
        series of outstanding Junior Subordinated Debentures; or     
 
  (iv) certain events in bankruptcy, insolvency or reorganization of the
       Corporation.
   
  The holders of a majority in aggregate outstanding principal amount of
Junior Subordinated Debentures of each series affected have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Debenture Trustee. The Debenture Trustee or the holders of
not less than 25% in aggregate outstanding principal amount of Junior
Subordinated Debentures of each series affected may declare the principal due
and payable immediately upon a Debenture Event of Default, and, in the case of
Corresponding Junior Subordinated Debentures, should the Debenture Trustee or
such holders of such Corresponding Junior Subordinated Debentures fail to make
such declaration, the holders of at least 25% in aggregate Liquidation Amount
of the Related Preferred Securities shall have such right. The holders of a
majority in aggregate outstanding principal amount of Junior Subordinated
Debentures of each series affected may annul such declaration. In the case of
Corresponding Junior Subordinated Debentures, should the holders of such
Corresponding Junior Subordinated Debentures fail to annul such declaration
and waive such default, the holders of a majority in aggregate Liquidation
Amount of the Related Preferred Securities affected shall have such right.
       
  The holders of a majority in aggregate outstanding principal amount of each
series of the Junior Subordinated Debentures affected thereby may, on behalf
of the holders of all the Junior Subordinated Debentures, waive any default,
except a default in the payment of principal or interest (unless such default
has been cured and a sum sufficient to pay all matured installments of
interest and principal due otherwise than by acceleration has been deposited
with the Debenture Trustee) or a default in respect of a covenant or provision
which under the Indenture cannot be modified or amended without the consent of
the holder of each outstanding Junior Subordinated Debenture. In the case of
Corresponding Junior Subordinated Debentures, should the holders of such
Corresponding Junior     
 
                                      18
<PAGE>
 
   
Subordinated Debentures fail to waive such default, the holders of a majority
in aggregate Liquidation Amount of the Related Preferred Securities affected
shall have such right. The Corporation is required to file annually with the
Debenture Trustee a certificate as to whether or not the Corporation is in
compliance with all the conditions and covenants applicable to it under the
Indenture.     
 
  In case a Debenture Event of Default shall occur and be continuing as to a
series of Corresponding Junior Subordinated Debentures, the Property Trustee
will have the right to declare the principal of and the interest on such
Corresponding Junior Subordinated Debentures, and any other amounts payable
under the Indenture, to be forthwith due and payable and to enforce its other
rights as a creditor with respect to such Corresponding Junior Subordinated
Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
   
  If a Debenture Event of Default with respect to a series of Corresponding
Junior Subordinated Debentures has occurred and is continuing and such event
is attributable to the failure of the Corporation to pay interest or principal
on such Corresponding Junior Subordinated Debentures on the date such interest
or principal is due and payable, a holder of Preferred Securities may
institute a legal proceeding directly against the Corporation for enforcement
of payment to such holder of the principal of or interest on such
Corresponding Junior Subordinated Debentures having a principal amount equal
to the aggregate Liquidation Amount of the Related Preferred Securities of
such holder (a "Direct Action"). The Corporation may not amend the Indenture
to remove the foregoing right to bring a Direct Action without the prior
written consent of the holders of all of the Preferred Securities outstanding.
If the right to bring a Direct Action is removed, the applicable Issuer may
become subject to the reporting obligations under the Exchange Act. The
Corporation shall have the right under the Indenture to set-off any payment
made to such holder of Preferred Securities by the Corporation in connection
with a Direct Action.     
   
  The holders of the Preferred Securities will not be able to exercise
directly any remedies other than those set forth in the preceding paragraph
available to the holders of the Junior Subordinated Debentures unless there
shall have been an event of default under the Trust Agreement. See
"Description of Preferred Securities--Events of Default; Notice."     
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
   
  The Indenture provides that the Corporation shall not consolidate with or
merge into any other Person or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, and no Person shall
consolidate with or merge into the Corporation or convey, transfer or lease
its properties and assets substantially as an entirety to the Corporation,
unless (i) in case the Corporation consolidates with or merges into another
Person or conveys or transfers its properties and assets substantially as an
entirety to any Person, the successor Person is organized under the laws of
the United States or any state or the District of Columbia, and such successor
Person expressly assumes the Corporation's obligations on the Junior
Subordinated Debentures issued under the Indenture; (ii) immediately after
giving effect thereto, no Debenture Event of Default, and no event which,
after notice or lapse of time or both, would become a Debenture Event of
Default, shall have occurred and be continuing; (iii) in the case of
Corresponding Junior Subordinated Debentures, such transaction is permitted
under the related Trust Agreement and Guarantee and does not give rise to any
breach or violation of the related Trust Agreement or Guarantee, and (iv)
certain other conditions as prescribed by the Indenture are met.     
 
  The general provisions of the Indenture do not afford holders of the Junior
Subordinated Debentures protection in the event of a highly leveraged or other
transaction involving the Corporation that may adversely affect holders of the
Junior Subordinated Debentures.
 
 
                                      19
<PAGE>
 
SATISFACTION AND DISCHARGE
   
  The Indenture provides that when, among other things, all Junior
Subordinated Debentures not previously delivered to the Debenture Trustee for
cancellation (i) have become due and payable or (ii) will become due and
payable at their Stated Maturity within one year, and the Corporation deposits
or causes to be deposited with the Debenture Trustee funds, in trust, for the
purpose and in an amount in the currency or currencies in which the Junior
Subordinated Debentures are payable sufficient to pay and discharge the entire
indebtedness on the Junior Subordinated Debentures not previously delivered to
the Debenture Trustee for cancellation, for the principal (and premium, if
any) and interest to the date of the deposit or to the Stated Maturity, as the
case may be, then the Indenture will cease to be of further effect (except as
to the Corporation's obligations to pay all other sums due pursuant to the
Indenture and to provide the officers' certificates and opinions of counsel
described therein), and the Corporation will be deemed to have satisfied and
discharged the Indenture.     
 
CONVERSION OR EXCHANGE
   
  If and to the extent indicated in the applicable Prospectus Supplement, the
Junior Subordinated Debentures of any series may be convertible or
exchangeable into Junior Subordinated Debentures of another series or into
Preferred Securities of another series. The specific terms on which Junior
Subordinated Debentures of any series may be so converted or exchanged will be
set forth in the applicable Prospectus Supplement. Such terms may include
provisions for conversion or exchange, either mandatory, at the option of the
holder, or at the option of the Corporation, in which case the number of
shares of Preferred Securities or other securities to be received by the
holders of Junior Subordinated Debentures would be calculated as of a time and
in the manner stated in the applicable Prospectus Supplement.     
 
SUBORDINATION
   
  In the Indenture, the Corporation has covenanted and agreed that any Junior
Subordinated Debentures issued thereunder will be subordinate and junior in
right of payment to all Senior Debt to the extent provided in the Indenture.
Upon any payment or distribution of assets of the Corporation to creditors
upon any liquidation, dissolution, winding up, reorganization, assignment for
the benefit of creditors, marshaling of assets or any bankruptcy, insolvency,
debt restructuring or similar proceedings in connection with any insolvency or
bankruptcy proceeding of the Corporation, the holders of Senior Debt will
first be entitled to receive payment in full of principal of (and premium, if
any) and interest, if any, on such Senior Debt before the holders of Junior
Subordinated Debentures or, in the case of Corresponding Junior Subordinated
Debentures, the Property Trustee, on behalf of the holders of Trust
Securities, will be entitled to receive or retain any payment in respect of
the principal of (and premium, if any) or interest, if any, on the Junior
Subordinated Debentures; provided, however, that holders of Senior Debt shall
not be entitled to receive payment of any such amount to the extent that such
holders would be required by the subordination provisions of such Senior Debt
to pay such amounts over to the obligees on trade accounts payable or other
liabilities arising in the ordinary course of the Corporation's business.     
   
  In the event of the acceleration of the maturity of any Junior Subordinated
Debentures, the holders of all Senior Debt outstanding at the time of such
acceleration will first be entitled to receive payment in full of all amounts
due thereon (including any amounts due upon acceleration) before the holders
of Junior Subordinated Debentures will be entitled to receive or retain any
payment in respect of the principal of (or premium, if any) or interest, if
any, on the Junior Subordinated Debentures; provided, however, that holders of
Senior Debt shall not be entitled to receive payment of any such amounts to
the extent that such holders would be required by the subordination provisions
of such Senior Debt to pay such amounts over to the obligees on trade accounts
payable or other liabilities arising in the ordinary course of the
Corporation's business.     
 
                                      20
<PAGE>
 
   
  No payments on account of principal (or premium, if any) or interest in
respect of the Junior Subordinated Debentures may be made if there shall have
occurred and be continuing a default in any payment with respect to Senior
Debt or an event of default with respect to any Senior Debt resulting in the
acceleration of the maturity thereof, or if any judicial proceeding shall be
pending with respect to any such default.     
   
  "Debt" means with respect to any Person, whether recourse is to all or a
portion of the assets of such Person and whether or not contingent, (i) every
obligation of such Person for money borrowed; (ii) every obligation of such
Person evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses; (iii) every reimbursement obligation of such Person with
respect to letters of credit, bankers' acceptances or similar facilities
issued for the account of such Person; (iv) every obligation of such Person
issued or assumed as the deferred purchase price of property or services (but
excluding trade accounts payable or accrued liabilities arising in the
ordinary course of business); (v) every capital lease obligation of such
Person; (vi) every obligation of such Person for claims in respect of
derivative products such as interest and foreign exchange rate contracts,
commodity contracts and similar arrangements; and (vii) every obligation of
the type referred to in clauses (i) through (vi) of another Person and all
dividends of another Person the payment of which, in either case, such Person
has guaranteed or is responsible or liable, directly or indirectly, as obligor
or otherwise.     
   
  "Senior Debt" means the principal of (and premium, if any) and interest, if
any (including interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to the Corporation whether or not
such claim for post-petition interest is allowed in such proceeding), on Debt,
whether incurred on or prior to the date of the Indenture or thereafter
incurred, unless, in the instrument creating or evidencing the same or
pursuant to which the same is outstanding, it is provided that such
obligations are not superior in right of payment to the Junior Subordinated
Debentures or to other Debt which is pari passu with, or subordinated to, the
Junior Subordinated Debentures; provided, however, that Senior Debt shall not
be deemed to include (i) any Debt of the Corporation which when incurred and
without respect to any election under Section 1111(b) of the United States
Bankruptcy Code of 1978, as amended, was without recourse to the Corporation;
(ii) any Debt of the Corporation to any of its subsidiaries; (iii) Debt to any
employee of the Corporation; (iv) Debt by its terms is subordinated to trade
accounts payable or accrued liabilities arising in the ordinary course of
business to the extent that payments made to the holders of such Debt by the
holders of the Junior Subordinated Debentures as a result of the subordination
provisions of the Indenture would be greater than such payments otherwise
would have been as a result of any obligation of such holders of such Debt to
pay amounts over to the obligees on such trade accounts payable or accrued
liabilities arising in the ordinary course of business as a result of
subordination provisions to which such Debt is subject; and (v) any other debt
securities issued pursuant to the Indenture.     
   
  The Indenture places no limitation on the amount of Senior Debt that may be
incurred by the Corporation. The Corporation expects from time to time to
incur additional indebtedness and other obligations constituting Senior Debt.
    
  The Indenture provides that the foregoing subordination provisions, insofar
as they relate to any particular issue of Junior Subordinated Debentures, may
be changed prior to such issuance. Any such change would be described in the
applicable Prospectus Supplement.
   
TRUST EXPENSES     
   
  Pursuant to the Expense Agreement, the Corporation, as holder of the Common
Securities, will irrevocably and unconditionally agree with each Issuer that
holds Junior Subordinated Debentures that the Corporation will pay to such
Issuer, and reimburse such Issuer for, the full amount of any costs, expenses
or liabilities of the Issuer, other than obligations of the Issuer to pay to
the holders of any     
 
                                      21
<PAGE>
 
   
Preferred Securities or other similar interests in the Issuer the amounts due
such holders pursuant to the terms of the Preferred Securities or such other
similar interests, as the case may be. Such payment obligation will include any
such costs, expenses or liabilities of the Issuer that are required by
applicable law to be satsified in connection with a termination of such Issuer.
    
GOVERNING LAW
 
  The Indenture and the Junior Subordinated Debentures will be governed by and
construed in accordance with the laws of the State of New York.
 
INFORMATION CONCERNING THE DEBENTURE TRUSTEE
 
  The Debenture Trustee shall have and be subject to all the duties and
responsibilities specified with respect to an indenture trustee under the Trust
Indenture Act. Subject to such provisions, the Debenture Trustee is under no
obligation to exercise any of the powers vested in it by the Indenture at the
request of any holder of Junior Subordinated Debentures, unless offered
reasonable indemnity by such holder against the costs, expenses and liabilities
which might be incurred thereby. The Debenture Trustee is not required to
expend or risk its own funds or otherwise incur personal financial liability in
the performance of its duties if the Debenture Trustee reasonably believes that
repayment or adequate indemnity is not reasonably assured to it.
 
CORRESPONDING JUNIOR SUBORDINATED DEBENTURES
   
  The Corresponding Junior Subordinated Debentures may be issued in one or more
series of Junior Subordinated Debentures under the Indenture with terms
corresponding to the terms of a series of Related Preferred Securities. In that
event, concurrently with the issuance of each Issuer's Preferred Securities,
such Issuer will invest the proceeds thereof and the consideration paid by the
Corporation for the Common Securities of such Issuer in such series of
Corresponding Junior Subordinated Debentures issued by the Corporation to such
Issuer. Each series of Corresponding Junior Subordinated Debentures will be in
the principal amount equal to the aggregate stated Liquidation Amount of the
Related Preferred Securities and the Common Securities of such Issuer and will
rank pari passu with all other series of Junior Subordinated Debentures.
Holders of the Related Preferred Securities for a series of Corresponding
Junior Subordinated Debentures will have the rights in connection with
modifications to the Indenture or upon occurrence of Debenture Events of
Default, as described under "--Modification of Indenture" and "--Debenture
Events of Default," unless provided otherwise in the Prospectus Supplement for
such Related Preferred Securities.     
   
  Unless otherwise specified in the applicable Prospectus Supplement, if a Tax
Event in respect of an Issuer shall occur and be continuing, the Corporation
may, at its option and subject to prior approval of the Federal Reserve if then
so required under applicable capital guidelines or policies, redeem the
Corresponding Junior Subordinated Debentures at any time within 90 days of the
occurrence of such Tax Event, in whole but not in part, subject to the
provisions of the Indenture and whether or not such Corresponding Junior
Subordinated Debentures are then otherwise redeemable at the option of the
Corporation. The redemption price for any Corresponding Junior Subordinated
Debentures shall be equal to 100% of the principal amount of such Corresponding
Junior Subordinated Debentures then outstanding plus accrued and unpaid
interest to the date fixed for redemption. For so long as the applicable Issuer
is the holder of all the outstanding Corresponding Junior Subordinated
Debentures of such series, the proceeds of any such redemption will be used by
the Issuer to redeem the corresponding Trust Securities in accordance with
their terms. The Corporation may not redeem a series of Corresponding Junior
Subordinated Debentures in part unless all accrued and unpaid interest has been
paid in full on all outstanding Corresponding Junior Subordinated Debentures of
such series for all interest periods terminating on or prior to the Redemption
Date.     
   
  The Corporation will covenant in the Indenture, as to each series of
Corresponding Junior Subordinated Debentures, that if and so long as (i) the
Issuer of the related series of Trust Securities     
 
                                       22
<PAGE>
 
   
is the holder of all such Corresponding Junior Subordinated Debentures, (ii) a
Tax Event in respect of such Issuer has occurred and is continuing and (iii)
the Corporation has elected, and has not revoked such election, to pay
Additional Sums (as defined under "Description of Preferred Securities--
Redemption or Exchange") in respect of such Trust Securities, the Corporation
will pay to such Issuer such Additional Sums. The Corporation will also
covenant, as to each series of Corresponding Junior Subordinated Debentures,
(i) to maintain directly or indirectly 100% ownership of the Common Securities
of the Issuer to which such Corresponding Junior Subordinated Debentures have
been issued, provided that certain successors which are permitted pursuant to
the Indenture may succeed to the Corporation's ownership of the Common
Securities, (ii) not to voluntarily terminate, wind-up or liquidate any
Issuer, except (a) in connection with a distribution of Corresponding Junior
Subordinated Debentures to the holders of the Preferred Securities in exchange
therefor upon liquidation of such Issuer, or (b) in connection with certain
mergers, consolidations or amalgamations permitted by the related Trust
Agreement, in either such case, if so specified in the applicable Prospectus
Supplement upon prior approval of the Federal Reserve if then so required
under applicable capital guidelines or policies, and (iii) to use its
reasonable efforts, consistent with the terms and provisions of the related
Trust Agreement, to cause such Issuer to remain classified as a grantor trust
and not as an association taxable as a corporation for United States federal
income tax purposes.     
 
                      DESCRIPTION OF PREFERRED SECURITIES
   
  Pursuant to the terms of the Trust Agreement for each Issuer, the Issuer
Trustees on behalf of such Issuer will issue the Preferred Securities and the
Common Securities. The Preferred Securities of a particular issue will
represent beneficial ownership interests in the Issuer and the holders thereof
will be entitled to a preference in certain circumstances with respect to
Distributions and amounts payable on redemption or liquidation over the Common
Securities of such Issuer, as well as other benefits as described in the
corresponding Trust Agreement. This summary of certain provisions of the
Preferred Securities and each Trust Agreement, which summarizes the material
terms thereof, does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of each Trust
Agreement, including the definitions therein of certain terms, and the Trust
Indenture Act, to each of which reference is hereby made. Wherever particular
defined terms of a Trust Agreement (as amended or supplemented from time to
time) are referred to herein or in a Prospectus Supplement, such defined terms
are incorporated herein or therein by reference. The form of the Trust
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part. Each of the Issuers is a legally separate entity
and the assets of one are not available to satisfy the obligations of any of
the others.     
 
GENERAL
   
  The Preferred Securities of an Issuer will rank pari passu, and payments
will be made thereon pro rata, with the Common Securities of that Issuer
except as described under "--Subordination of Common Securities." Legal title
to the Corresponding Junior Subordinated Debentures will be held by the
Property Trustee in trust for the benefit of the holders of the related
Preferred Securities and Common Securities. Each Guarantee Agreement executed
by the Corporation for the benefit of the holders of an Issuer's Trust
Securities (the "Guarantee") will be a guarantee on a subordinated basis with
respect to the related Trust Securities but will not guarantee payment of
Distributions or amounts payable on redemption or liquidation of such Trust
Securities when the related Issuer does not have funds on hand available to
make such payments. See "Description of Guarantees."     
 
DISTRIBUTIONS
 
  Distributions on the Preferred Securities will be cumulative, will
accumulate from the date of original issuance and will be payable on such
dates as specified in the applicable Prospectus
 
                                      23
<PAGE>
 
   
Supplement. In the event that any date on which Distributions are payable on
the Preferred Securities is not a Business Day (as defined below), payment of
the Distribution payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect
to any such delay) except that, if such Business Day is in the next succeeding
calendar year, payment of such Distribution shall be made on the immediately
preceding Business Day, in either case with the same force and effect as if
made on such date (each date on which Distributions are payable in accordance
with the foregoing, a "Distribution Date"). A "Business Day" shall mean any
day other than a Saturday or a Sunday, or a day on which banking institutions
in The City of New York are authorized or required by law or executive order
to remain closed or a day on which the corporate trust office of the Property
Trustee or the Debenture Trustee is closed for business.     
   
  Each Issuer's Preferred Securities represent beneficial ownership interests
in the applicable Issuer, and the Distributions on each Preferred Security
will be payable at a rate specified in the applicable Prospectus Supplement
for such Preferred Securities. The amount of Distributions payable for any
period will be computed on the basis of a 360-day year of twelve 30-day months
unless otherwise specified in the applicable Prospectus Supplement.
Distributions to which holders of Preferred Securities are entitled will
accumulate additional Distributions at the rate per annum if and as specified
in the applicable Prospectus Supplement. The term "Distributions" as used
herein includes any such additional Distributions unless otherwise stated.
       
  If provided in the applicable Prospectus Supplement, the Corporation has the
right under the Indenture, pursuant to which it will issue the Corresponding
Junior Subordinated Debentures, to defer the payment of interest at any time
or from time to time on any series of the Corresponding Junior Subordinated
Debentures for up to such number of consecutive interest payment periods which
will be specified in such Prospectus Supplement relating to such series (each,
an "Extension Period"), provided that no Extension Period may extend beyond
the Stated Maturity of the Corresponding Junior Subordinated Debentures. As a
consequence of any such deferral, Distributions on the Related Preferred
Securities would be deferred (but would continue to accumulate additional
Distributions thereon at the rate per annum set forth in the Prospectus
Supplement for such Preferred Securities) by the Issuer of such Preferred
Securities during any such Extension Period. During such Extension Period, the
Corporation may not, and may not permit any subsidiary of the Corporation to,
(i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of the
Corporation's capital stock, (ii) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Corporation that rank pari passu with or junior in interest to the
Corresponding Junior Subordinated Debentures or (iii) make any guarantee
payments with respect to any guarantee by the Corporation of debt securities
of any subsidiary of the Corporation if such guarantee ranks pari passu with
or junior in interest to the Corresponding Junior Subordinated Debentures
(other than (a) dividends or distributions in capital stock of the
Corporation, (b) any declaration of a dividend in connection with the
implementation of a stockholders' rights plan, the redemption or repurchase of
any such rights pursuant thereto, (c) payments under the Guarantee with
respect to such Preferred Securities and (d) purchases of common stock related
to the issuance of common stock or rights under any of the Corporation's
benefit plans for its directors, officers or employees, related to the
issuance of common stock or rights under a dividend reinvestment and stock
purchase plan, or related to the issuance of common stock (or securities
convertible into or exchangeable for common stock) as consideration in an
acquisition transaction).     
   
  The revenue of each Issuer available for distribution to holders of its
Preferred Securities will be limited to payments under the Corresponding
Junior Subordinated Debentures in which the Issuer will invest the proceeds
from the issuance and sale of its Trust Securities and the related Expense
Agreement. See "Description of Junior Subordinated Debentures--Corresponding
Junior Subordinated Debentures." If the Corporation does not make interest
payments on such Corresponding Junior     
 
                                      24
<PAGE>
 
   
Subordinated Debentures, the Property Trustee will not have funds available to
pay Distributions on the Related Preferred Securities. The payment of
Distributions (if and to the extent the Issuer has funds legally available for
the payment of such Distributions and cash sufficient to make such payments)
is guaranteed by the Corporation on the basis set forth herein under
"Description of Guarantees."     
 
  Distributions on the Preferred Securities will be payable to the holders
thereof as they appear on the register of such Issuer on the relevant record
dates, which, as long as the Preferred Securities remain in book-entry form,
will be one Business Day prior to the relevant Distribution Date. Subject to
any applicable laws and regulations and the provisions of the applicable Trust
Agreement, each such payment will be made as described under "Book-Entry
Issuance." In the event any Preferred Securities are not in book-entry form,
the relevant record date for such Preferred Securities shall be the date at
least 15 days prior to the relevant Distribution Date, as specified in the
applicable Prospectus Supplement.
 
REDEMPTION OR EXCHANGE
 
  Mandatory Redemption. Upon the repayment or redemption, in whole or in part,
of any Corresponding Junior Subordinated Debentures, whether at maturity or
upon earlier redemption as provided in the Indenture, the proceeds from such
repayment or redemption shall be applied by the Property Trustee to redeem a
Like Amount (as defined below) of the Trust Securities, upon not less than 30
nor more than 60 days notice, at a redemption price (the "Redemption Price")
equal to the aggregate Liquidation Amount of such Trust Securities plus
accumulated but unpaid Distributions thereon to the date of redemption (the
"Redemption Date") and the related amount of the premium, if any, paid by the
Corporation upon the concurrent redemption of such Corresponding Junior
Subordinated Debentures. See "Description of Junior Subordinated Debentures--
Redemption". If less than all of any series of Corresponding Junior
Subordinated Debentures are to be repaid or redeemed on a Redemption Date,
then the proceeds from such repayment or redemption shall be allocated to the
redemption pro rata of the related Preferred Securities and the Common
Securities. The amount of premium, if any, paid by the Corporation upon the
redemption of all or any part of any series of any Corresponding Junior
Subordinated Debentures to be repaid or redeemed on a Redemption Date shall be
allocated to the redemption pro rata of the related Preferred Securities and
the Common Securities.
   
  The Corporation will have the right to redeem any series of Corresponding
Junior Subordinated Debentures (i) on or after such date as may be specified
in the applicable Prospectus Supplement, in whole at any time or in part from
time to time, (ii) at any time, in whole (but not in part), upon the
occurrence of a Tax Event or Capital Treatment Event, in either case subject
to receipt of prior approval by the Federal Reserve if then required under
applicable capital guidelines or policies.     
   
  Tax Event or Capital Treatment Event Redemption. If a Tax Event or Capital
Treatment Event in respect of a series of Preferred Securities and Common
Securities shall occur and be continuing, the Corporation has the right to
redeem the Corresponding Junior Subordinated Debentures in whole (but not in
part) and thereby cause a mandatory redemption of such Preferred Securities
and Common Securities in whole (but not in part) at the Redemption Price
within 90 days following the occurrence of such Tax Event or Capital Treatment
Event. In the event a Tax Event or Capital Treatment Event in respect of a
series of Preferred Securities and Common Securities has occurred and is
continuing and the Corporation does not elect to redeem the Corresponding
Junior Subordinated Debentures and thereby cause a mandatory redemption of
such Preferred Securities and Common Securities or to liquidate the related
Issuer and cause the Corresponding Junior Subordinated Debentures to be
distributed to holders of such Preferred Securities and Common Securities in
exchange therefor upon liquidation of the Issuer as described above, such
Preferred Securities will remain outstanding and Additional Sums (as defined
below) may be payable on the Corresponding Junior Subordinated Debentures.
    
                                      25

  Possible Tax Law Changes. On March 19, 1996, the Revenue Reconciliation Bill
of 1996 (the "Bill"), the revenue portion of President Clinton's budget
proposal, was released. The Bill would have among other things, generally
denied interest deductions for interest on an instrument issued by a
corporation that has a maximum weighted average maturity of more than 40
years. The Bill would also have generally denied interest deductions for
interest on an instrument issued by a corporation that has a maximum term of
more than 20 years and that is not shown as indebtedness on the separate
balance sheet of the issuer or, where the instrument is issued to a related
party (other than a corporation), where the holder or some other related party
issues a related instrument that is not shown as indebtedness on the issuer's
consolidated balance sheet. For purposes of determining the weighted average
maturity or the term of an instrument, any right to extend would be treated as
exercised. The above-described provisions of the Bill were proposed to be
effective generally for instruments issued on or after December 7, 1995. If
either provision were to apply to the Junior Subordinated Debentures, the
Corporation would not be able to deduct interest on the Junior Subordinated
Debentures. However, on March 29, 1996, the Chairmen of the Senate Finance and
House Ways and Means Committees issued a joint statement (the "Joint
Statement") to the effect that it was their intention that the effective date
of the President's legislative proposals, if adopted, would be no earlier than
the date of appropriate Congressional action. In addition, subsequent to the
publication of the Joint Statement, Senator Daniel Patrick Moynihan and
Representatives Sam M. Gibbons and Charles B. Rangel wrote letters to Treasury
Department officials concurring with the view expressed in the Joint Statement
(the "Democrat Letters"). If the principles contained in the Joint Statement
and the Democrat Letters were followed and the Bill was enacted, such
legislation would not apply to the Junior Subordinated Debentures. There can
be no assurance, however, that current or future legislative proposals or
final legislation will not adversely affect the ability of the Corporation to
deduct interest on the Junior Subordinated Debentures. Moreover, such a change
could give rise to a Tax Event, which may permit the Corporation to cause a
redemption of the Related Preferred Securities.     
   
  Distribution of Corresponding Junior Subordinated Debentures. Subject to the
Corporation having received prior approval on the Federal Reserve to do so if
then required under applicable capital guidelines or policies, the Corporation
has the right at any time, to liquidate the related Issuer and, after
satisfaction of the liabilities of creditors of such Issuer as provided by
applicable law, cause such Corresponding Junior Subordinated Debentures in
respect of the Preferred Securities and Common Securities issued by such
Issuer to be distributed to the holders of such Preferred Securities and
Common Securities in exchange therefor upon liquidation of the Issuer.     
 
  "Additional Sums" means the additional amounts as may be necessary in order
that the amount of Distributions then due and payable by an Issuer on the
outstanding Preferred Securities and Common Securities of the Issuer shall not
be reduced as a result of any additional taxes, duties and other governmental
charges to which such Issuer has become subject as a result of a Tax Event.
   
  "Like Amount" means (i) with respect to a redemption of any series of Trust
Securities, Trust Securities of such series having a Liquidation Amount (as
defined below) equal to that portion of the principal amount of Corresponding
Junior Subordinated Debentures to be contemporaneously redeemed in accordance
with the Indenture, allocated to the Common Securities and to the Preferred
Securities pro rata based upon the relative Liquidation Amounts of such
classes and the proceeds of which will be used to pay the Redemption Price of
such Trust Securities, and (ii) with respect to a distribution of
Corresponding Junior Subordinated Debentures to holders of any series of Trust
Securities in exchange therefor in connection with a dissolution or
liquidation of the related Issuer, Corresponding Junior Subordinated
Debentures having a principal amount equal to the Liquidation Amount of the
Trust Securities of the holder to whom such Corresponding Junior Subordinated
Debentures would be distributed.     
 
  "Liquidation Amount" means the stated amount of $25 per Trust Security.
 
                                      26
<PAGE>
 
   
  "Tax Event" with respect to an Issuer means the receipt by the Issuer of a
series of Preferred Securities of an opinion of counsel experienced in such
matters to the effect that, as a result of any amendment to, or change
(including any announced proposed change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein, or as a result of any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or which proposed change,
pronouncement or decision is announced on or after the date of issuance of
such Preferred Securities under the Trust Agreement, there is more than an
insubstantial risk that (i) such Issuer is, or will be within 90 days of the
date of such opinion, subject to United States federal income tax with respect
to income received or accrued on the corresponding series of Corresponding
Junior Subordinated Debentures, (ii) interest payable by the Corporation on
such series of Corresponding Junior Subordinated Debentures is not, or within
90 days of the date of such opinion, will not be, deductible by the
Corporation, in whole or in part, for United States federal income tax
purposes, or (iii) such Issuer is, or will be within 90 days of the date of
such opinion, subject to more than a de minimis amount of other taxes, duties
or other governmental charges.     
   
  After the liquidation date fixed for any distribution of Corresponding
Junior Subordinated Debentures for any series of Preferred Securities (i) such
series of Preferred Securities will no longer be deemed to be outstanding,
(ii) the depositary or its nominee, as the record holder of such series of
Preferred Securities, will receive a registered global certificate or
certificates representing the Corresponding Junior Subordinated Debentures to
be delivered upon such distribution and (iii) any certificates representing
such series of Preferred Securities not held by DTC or its nominee will be
deemed to represent the Corresponding Junior Subordinated Debentures having a
principal amount equal to the stated Liquidation Amount of such series of
Preferred Securities, and bearing accrued and unpaid interest in an amount
equal to the accrued and unpaid Distributions on such series of Preferred
Securities until such certificates are presented to the Administrative
Trustees or their agent for transfer or reissuance.     
 
  There can be no assurance as to the market prices for the Preferred
Securities or the Corresponding Junior Subordinated Debentures that may be
distributed in exchange for Preferred Securities if a dissolution and
liquidation of an Issuer were to occur. Accordingly, the Preferred Securities
that an investor may purchase, or the Corresponding Junior Subordinated
Debentures that the investor may receive on dissolution and liquidation of an
Issuer, may trade at a discount to the price that the investor paid to
purchase the Preferred Securities offered hereby.
 
REDEMPTION PROCEDURES
   
  Preferred Securities redeemed on each Redemption Date shall be redeemed at
the Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Corresponding Junior Subordinated Debentures. Redemptions of
the Preferred Securities shall be made and the Redemption Price shall be
payable on each Redemption Date only to the extent that the related Issuer has
funds on hand available for the payment of such Redemption Price. See also "--
Subordination of Common Securities."     
   
  If an Issuer gives a notice of redemption in respect of its Preferred
Securities, then, by 12:00 noon, New York City time, on the Redemption Date,
to the extent funds are available, the Property Trustee will deposit
irrevocably with DTC funds sufficient to pay the applicable Redemption Price
and will give DTC irrevocable instructions and authority to pay the Redemption
Price to the holders of such Preferred Securities. See "Book-Entry Issuance."
If such Preferred Securities are no longer in book-entry form, the Property
Trustee, to the extent funds are available, will irrevocably deposit with the
paying agent for such Preferred Securities funds sufficient to pay the
applicable Redemption Price and will give such paying agent irrevocable
instructions and authority to pay the Redemption Price to the     
 
                                      27
<PAGE>
 
   
holders thereof upon surrender of their certificates evidencing such Preferred
Securities. Notwithstanding the foregoing, Distributions payable on or prior
to the Redemption Date for any Preferred Securities called for redemption
shall be payable to the holders of such Preferred Securities on the relevant
record dates for the related Distribution Dates. If notice of redemption shall
have been given and funds deposited as required, then upon the date of such
deposit, all rights of the holders of such Preferred Securities so called for
redemption will cease, except the right of the holders of such Preferred
Securities to receive the Redemption Price, but without interest on such
Redemption Price, and such Preferred Securities will cease to be outstanding.
In the event that any date fixed for redemption of Preferred Securities is not
a Business Day, then payment of the Redemption Price payable on such date will
be made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day. In the event that payment of the
Redemption Price in respect of Preferred Securities called for redemption is
improperly withheld or refused and not paid either by the Issuer or by the
Corporation pursuant to the Guarantee as described under "Description of
Guarantees," Distributions on such Preferred Securities will continue to
accrue at the then applicable rate, from the Redemption Date originally
established by the Issuer for such Preferred Securities to the date such
Redemption Price is actually paid, in which case the actual payment date will
be the date fixed for redemption for purposes of calculating the Redemption
Price.     
   
  Subject to applicable law (including, without limitation, United States
federal securities law), the Corporation or its subsidiaries may at any time
and from time to time purchase outstanding Preferred Securities by tender, in
the open market or by private agreement.     
 
  Payment of the Redemption Price on the Preferred Securities and any
distribution of Corresponding Junior Subordinated Debentures to holders of
Preferred Securities shall be made to the applicable recordholders thereof as
they appear on the register for such Preferred Securities on the relevant
record date, which shall be one Business Day prior to the relevant Redemption
Date or liquidation date, as applicable; provided, however, that in the event
that any Preferred Securities are not in book-entry form, the relevant record
date for such Preferred Securities shall be a date at least 15 days prior to
the Redemption Date or liquidation date, as applicable, as specified in the
applicable Prospectus Supplement.
   
  If less than all of the Preferred Securities and Common Securities issued by
an Issuer are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of such Preferred Securities and Common Securities to be
redeemed shall be allocated pro rata to the Preferred Securities and the
Common Securities based upon the relative Liquidation Amounts of such classes.
The particular Preferred Securities to be redeemed shall be selected on a pro
rata basis not more than 60 days prior to the Redemption Date by the Property
Trustee from the outstanding Preferred Securities not previously called for
redemption, by such method as the Property Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $25 or an integral multiple of $25 in excess thereof) of the
Liquidation Amount of Preferred Securities of a denomination larger than $25.
The Property Trustee shall promptly notify the trust registrar in writing of
the Preferred Securities selected for redemption and, in the case of any
Preferred Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed. For all purposes of each Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of
Preferred Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the portion of the aggregate
Liquidation Amount of Preferred Securities which has been or is to be
redeemed.     
   
  Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Trust Securities to be
redeemed at its registered address.

SUBORDINATION OF COMMON SECURITIES
 
  Payment of Distributions on, and the Redemption Price of, each Issuer's
Preferred Securities and Common Securities, as applicable, shall be made pro
rata based on the Liquidation Amount of such Preferred Securities and Common
Securities; provided, however, that if on any Distribution Date or Redemption
Date a Debenture Event of Default shall have occurred and be continuing, no
payment of any Distribution on, or Redemption Price of, any of the Issuer's
Common Securities, and no other payment on account of the redemption,
liquidation or other acquisition of such Common Securities, shall be made
unless payment in full in cash of all accumulated and unpaid Distributions on
all of the Issuer's outstanding Preferred Securities for all Distribution
periods terminating on or prior thereto, or in the case of payment of the
Redemption Price the full amount of such Redemption Price on all of the
Issuer's outstanding Preferred Securities then called for redemption, shall
have been made or provided for, and all funds available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions on, or Redemption Price of, the Issuer's Preferred Securities
then due and payable.
   
  In the case of any event of default under the applicable Trust Agreement
resulting from a Debenture Event of Default, the Corporation as holder of such
Issuer's Common Securities will be deemed to have waived any right to act with
respect to any such event of default under the applicable Trust Agreement
until the effect of all such events of default with respect to such Preferred
Securities have been cured, waived or otherwise eliminated. Until all events
of default under the applicable Trust Agreement with respect to the Preferred
Securities have been so cured, waived or otherwise eliminated, the Property
Trustee shall act solely on behalf of the holders of such Preferred Securities
and not on behalf of the Corporation as holder of the Issuer's Common
Securities, and only the holders of such Preferred Securities will have the
right to direct the Property Trustee to act on their behalf.     
 
LIQUIDATION DISTRIBUTION UPON TERMINATION
   
  Pursuant to each Trust Agreement, each Issuer shall automatically terminate
upon expiration of its term and shall terminate on the first to occur of: (i)
certain events of bankruptcy, dissolution or liquidation of the holder of the
Common Securities; (ii) the distribution of a Like Amount of the Corresponding
Junior Subordinated Debentures to the holders of its Trust Securities, if the
Corporation, as Depositor, has given written direction to the Property Trustee
to terminate such Issuer (subject to the Corporation having received prior
approval of the Federal Reserve if so required under applicable capital
guidelines or policies); (iii) redemption of all of the Issuer's Preferred
Securities as described under "--Redemption or Exchange--Mandatory
Redemption"; and (iv) the entry of an order for the dissolution of the Issuer
by a court of competent jurisdiction.     
   
  If an early termination occurs as described in clause (i), (ii) or (iv)
above, the Issuer shall be liquidated by the Issuer Trustees as expeditiously
as the Issuer Trustees determine to be possible by distributing, after
satisfaction of liabilities to creditors of such Issuer as provided by
applicable law, to the holders of such Trust Securities in exchange therefor a
Like Amount of the Corresponding Junior Subordinated Debentures, unless such
distribution is determined by the Property Trustee not to be practical, in
which event such holders will be entitled to receive out of the assets of the
Issuer available for distribution to holders, after satisfaction of
liabilities to creditors of such Issuer as provided by applicable law, an
amount equal to, in the case of holders of Preferred Securities, the aggregate
of the Liquidation Amount plus accrued and unpaid Distributions thereon to the
date of payment (such amount being the "Liquidation Distribution"). If such
Liquidation Distribution can be paid only in part because such Issuer has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then the amounts payable directly by such Issuer on its
Preferred Securities shall be paid on a pro rata basis. The holder(s) of such
Issuer's Common Securities will be entitled to receive distributions upon any
such liquidation pro rata with the holders of its Preferred Securities, except
that if a Debenture Event of Default has occurred and is continuing, the
Preferred Securities shall have a priority over the Common Securities.     
 
                                      29

EVENTS OF DEFAULT; NOTICE
   
  Any one of the following events constitutes an "Event of Default" under each
Trust Agreement with respect to the Preferred Securities issued thereunder
(whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):     
 
    (i) the occurrence of a Debenture Event of Default under the Indenture
        (see "Description of Junior Subordinated Debentures--Debenture
        Events of Default"); or
 
    (ii) default by the Property Trustee in the payment of any Distribution
         when it becomes due and payable, and continuation of such default
         for a period of 30 days; or
 
    (iii) default by the Property Trustee in the payment of any Redemption
          Price of any Trust Security when it becomes due and payable; or
       
    (iv) default in the performance, or breach, in any material respect, of
         any covenant or warranty of the Issuer Trustees in such Trust
         Agreement (other than a covenant or warranty a default in the
         performance of which or the breach of which is dealt with in
         clause (ii) or (iii) above), and continuation of such default or
         breach for a period of 60 days after there has been given, by
         registered or certified mail, to the defaulting Issuer Trustee or
         Trustees by the holders of at least 25% in aggregate Liquidation
         Amount of the outstanding Preferred Securities of the applicable
         Issuer, a written notice specifying such default or breach and
         requiring it to be remedied and stating that such notice is a
         "Notice of Default" under such Trust Agreement; or     
       
    (v) the occurrence of certain events of bankruptcy or insolvency with
        respect to the Property Trustee and the failure by the Corporation
        to appoint a successor Property Trustee within 60 days thereof.
            
  Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit
notice of such Event of Default to the holders of such Issuer's Preferred
Securities, the Administrative Trustees and the Corporation, as Depositor,
unless such Event of Default shall have been cured or waived. The Corporation,
as Depositor, and the Administrative Trustees are required to file annually
with the Property Trustee a certificate as to whether or not they are in
compliance with all the conditions and covenants applicable to them under each
Trust Agreement.
   
  If a Debenture Event of Default has occurred and is continuing, the
Preferred Securities shall have a preference over the Common Securities as
described above. See "Subordination of Common Securities" and "--Liquidation
Distribution Upon Termination." The existence of an Event of Default does not
entitle the holders of Preferred Securities to accelerate the maturity
thereof.     
 
REMOVAL OF ISSUER TRUSTEES
 
  Unless a Debenture Event of Default shall have occurred and be continuing,
any Issuer Trustee may be removed at any time by the holder of the Common
Securities. If a Debenture Event of Default has occurred and is continuing,
the Property Trustee and the Delaware Trustee may be removed at such time by
the holders of a majority in Liquidation Amount of the outstanding Preferred
Securities. In no event will the holders of the Preferred Securities have the
right to vote to appoint, remove or replace the Administrative Trustees, which
voting rights are vested exclusively in the Corporation as the holder of the
Common Securities. No resignation or removal of an Issuer Trustee and no
appointment of a successor trustee shall be effective until the acceptance of
appointment by the successor trustee in accordance with the provisions of the
applicable Trust Agreement.
 
                                      30
<PAGE>
 
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
   
  Unless an Event of Default shall have occurred and be continuing, at any
time or from time to time, for the purpose of meeting the legal requirements
of the Trust Indenture Act or of any jurisdiction in which any part of the
Trust Property may at the time be located, the Corporation, as the holder of
the Common Securities, and the Administrative Trustees shall have power to
appoint one or more persons either to act as a co-trustee, jointly with the
Property Trustee, of all or any part of such Trust Property, or to act as
separate trustee of any such property, in either case with such powers as may
be provided in the instrument of appointment, and to vest in such person or
persons in such capacity any property, title, right or power deemed necessary
or desirable, subject to the provisions of the applicable Trust Agreement. In
case a Debenture Event of Default has occurred and is continuing, the Property
Trustee alone shall have power to make such appointment.     
 
MERGER OR CONSOLIDATION OF ISSUER TRUSTEES
   
  Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which such Trustee shall be a party, or any
Person succeeding to all or substantially all the corporate trust business of
such Trustee, shall be the successor of such Trustee under each Trust
Agreement, provided such Person shall be otherwise qualified and eligible.
    
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE ISSUERS
   
  An Issuer may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described below. An Issuer may, at the request of the Corporation, with the
consent of the Administrative Trustees and without the consent of the holders
of the Preferred Securities, merge with or into, consolidate, amalgamate, or
be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, a trust organized as such under the laws of
any State; provided, that (i) such successor entity either (a) expressly
assumes all of the obligations of such Issuer with respect to the Preferred
Securities or (b) substitutes for the Preferred Securities other securities
having substantially the same terms as the Preferred Securities (the
"Successor Securities") so long as the Successor Securities rank the same as
the Preferred Securities in priority with respect to distributions and
payments upon liquidation, redemption and otherwise, (ii) the Corporation
expressly appoints a trustee of such successor entity possessing the same
powers and duties as the Property Trustee as the holder of the Corresponding
Junior Subordinated Debentures, (iii) the Successor Securities are listed, or
any Successor Securities will be listed upon notification of issuance, on any
national securities exchange or other organization on which the Preferred
Securities are then listed, if any, (iv) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not cause the
Preferred Securities to be downgraded by any nationally recognized statistical
rating organization which gives ratings on the Preferred Securities, (v) such
merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
holders of the Preferred Securities (including any Successor Securities) in
any material respect, (vi) such successor entity has a purpose identical to
that of the Issuer, (vii) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Corporation has received an
opinion from independent counsel to the Issuer experienced in such matters to
the effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Preferred Securities
(including any Successor Securities) in any material respect, and (b)
following such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease, neither the Issuer nor such successor entity will be
required to register as an investment company under the Investment Company Act
of 1940, as amended (the "Investment Company Act"), and (viii) the Corporation
or any permitted successor or assignee owns all of the Common Securities of
such     
 
                                      31
<PAGE>
 
   
successor entity and guarantees the obligations of such successor entity under
the Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, an Issuer shall not, except with the consent of
holders of 100% in Liquidation Amount of the Preferred Securities,
consolidate, amalgamate, merge with or into, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to
any other entity or permit any other entity to consolidate, amalgamate, merge
with or into, or replace it if such consolidation, amalgamation, merger,
replacement, conveyance, transfer or lease would cause the Issuer or the
successor entity to be classified as an association taxable as a corporation
or as other than a grantor trust for United States Federal income tax
purposes.     
 
VOTING RIGHTS; AMENDMENT OF EACH TRUST AGREEMENT
 
  Except as provided below and under "Description of Guarantees--Amendments
and Assignment" and as otherwise required by law and the applicable Trust
Agreement, the holders of the Preferred Securities will have no voting rights.
   
  Each Trust Agreement may be amended from time to time by the Corporation,
the Property Trustee and the Administrative Trustees, without the consent of
the holders of the Preferred Securities (i) to cure any ambiguity, correct or
supplement any provisions in such Trust Agreement that may be inconsistent
with any other provision, or to make any other provisions with respect to
matters or questions arising under such Trust Agreement, which shall not be
inconsistent with the other provisions of such Trust Agreement, or (ii) to
modify, eliminate or add to any provisions of such Trust Agreement to such
extent as shall be necessary to ensure that the Issuer will be classified for
United States federal income tax purposes as other than an association taxable
as a corporation or as a grantor trust at all times that any Trust Securities
are outstanding or to ensure that the Issuer will not be required to register
as an "investment company" under the Investment Company Act; provided,
however, that in the case of either clause (i) or clause (ii), such action
shall not adversely affect in any material respect the interests of any holder
of Preferred Securities, and any amendments of such Trust Agreement shall
become effective when notice thereof is given to the holders of Trust
Securities. Each Trust Agreement may be amended by the Issuer Trustees and the
Corporation with (i) the consent of holders representing not less than a
majority (based upon Liquidation Amounts) of the outstanding Trust Securities,
and (ii) receipt by the Issuer Trustees of an opinion of counsel to the effect
that such amendment or the exercise of any power granted to the Issuer
Trustees in accordance with such amendment will not affect the Issuer's status
as a grantor trust for United States federal income tax purposes or the
Issuer's exemption from status as an "investment company" under the Investment
Company Act, provided that without the consent of each holder of Trust
Securities, such Trust Agreement may not be amended to (i) change the amount
or timing of any Distribution on the Trust Securities or otherwise adversely
affect the amount of any Distribution required to be made in respect of the
Trust Securities as of a specified date or (ii) restrict the right of a holder
of Trust Securities to institute suit for the enforcement of any such payment
on or after such date.     
   
  So long as any Corresponding Junior Subordinated Debentures are held by the
Property Trustee, the Issuer Trustees shall not (i) direct the time, method
and place of conducting any proceeding for any remedy available to the
Debenture Trustee, or executing any trust or power conferred on the Property
Trustee with respect to such Corresponding Junior Subordinated Debentures,
(ii) waive any past default that is waivable under the Indenture, (iii)
exercise any right to rescind or annul a declaration that the principal of all
the Junior Subordinated Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or such
Corresponding Junior Subordinated Debentures, where such consent shall be
required, without, in each case, obtaining the prior approval of the holders
of a majority in aggregate Liquidation Amount of all outstanding Preferred
Securities; provided, however, that where a consent under the Indenture would
require the consent of each holder of Corresponding Junior Subordinated
Debentures affected thereby, no such consent shall be given by the Property
Trustee without the prior consent of each holder of the     
 
                                      32
<PAGE>
 
   
corresponding Preferred Securities. The Issuer Trustees shall not revoke any
action previously authorized or approved by a vote of the holders of the
Preferred Securities except by subsequent vote of the holders of the Preferred
Securities. The Property Trustee shall notify each holder of Preferred
Securities of any notice of default with respect to the Corresponding Junior
Subordinated Debentures. In addition to obtaining the foregoing approvals of
the holders of the Preferred Securities, prior to taking any of the foregoing
actions, the Issuer Trustees shall obtain an opinion of counsel experienced in
such matters to the effect that the Issuer will not be classified as an
association taxable as a corporation for United States Federal income tax
purposes on account of such action and such action would not cause the Issuer
to be classified as other than a grantor trust for United States federal
income tax purposes.     
 
  Any required approval of holders of Preferred Securities may be given at a
meeting of holders of Preferred Securities convened for such purpose or
pursuant to written consent. The Property Trustee will cause a notice of any
meeting at which holders of Preferred Securities are entitled to vote, or of
any matter upon which action by written consent of such holders is to be
taken, to be given to each holder of record of Preferred Securities in the
manner set forth in each Trust Agreement.
 
  No vote or consent of the holders of Preferred Securities will be required
for an Issuer to redeem and cancel its Preferred Securities in accordance with
the applicable Trust Agreement.
 
  Notwithstanding that holders of Preferred Securities are entitled to vote or
consent under any of the circumstances described above, any of the Preferred
Securities that are owned by the Corporation, the Issuer Trustees or any
affiliate of the Corporation or any Issuer Trustees, shall, for purposes of
such vote or consent, be treated as if they were not outstanding.
 
GLOBAL PREFERRED SECURITIES
 
  The Preferred Securities of a series may be issued in whole or in part in
the form of one or more Global Preferred Securities that will be deposited
with, or on behalf of, the Depositary identified in the Prospectus Supplement
relating to such series. Unless otherwise indicated in the applicable
Prospectus Supplement for such series, the Depositary will be DTC. Global
Preferred Securities may be issued only in fully registered form and in either
temporary or permanent form. Unless and until it is exchanged in whole or in
part for the individual Preferred Securities represented thereby, a Global
Preferred Security may not be transferred except as a whole by the Depositary
for such Global Preferred Security to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by the Depositary or any nominee to a successor Depositary or
any nominee of such successor.
 
  The specific terms of the depositary arrangement with respect to a series of
Preferred Securities will be described in the Prospectus Supplement relating
to such series. The Corporation anticipates that the following provisions will
generally apply to depositary arrangements.
 
  Upon the issuance of a Global Preferred Security, and the deposit of such
Global Preferred Security with or on behalf of the Depositary, the Depositary
for such Global Preferred Security or its nominee will credit, on its book-
entry registration and transfer system, the respective aggregate Liquidation
Amounts of the individual Preferred Securities represented by such Global
Preferred Securities to the accounts of Participants. Such accounts shall be
designated by the dealers, underwriters or agents with respect to such
Preferred Securities or by the Corporation if such Preferred Securities are
offered and sold directly by the Corporation. Ownership of beneficial
interests in a Global Preferred Security will be limited to Participants or
persons that may hold interests through Participants. Ownership of beneficial
interests in such Global Preferred Security will be shown on, and the transfer
of that ownership will be effected only through, records maintained by the
applicable Depositary or its nominee (with respect to interests of
Participants) and the records of Participants
 
                                      33
<PAGE>
 
(with respect to interests of persons who hold through Participants). The laws
of some states require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Preferred
Security.
 
  So long as the Depositary for a Global Preferred Security, or its nominee,
is the registered owner of such Global Preferred Security, such Depositary or
such nominee, as the case may be, will be considered the sole owner or holder
of the Preferred Securities represented by such Global Preferred Security for
all purposes under the Indenture governing such Preferred Securities. Except
as provided below, owners of beneficial interests in a Global Preferred
Security will not be entitled to have any of the individual Preferred
Securities of the series represented by such Global Preferred Security
registered in their names, will not receive or be entitled to receive physical
delivery of any such Preferred Securities of such series in definitive form
and will not be considered the owners or holders thereof under the Indenture.
 
  Payments of principal of (and premium, if any) and interest on individual
Preferred Securities represented by a Global Preferred Security registered in
the name of a Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Preferred
Security representing such Preferred Securities. None of the Corporation, the
Property Trustee, any Paying Agent, or the Securities Registrar for such
Preferred Securities will have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests of the Global Preferred Security representing such Preferred
Securities or for maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.
   
  The Corporation expects that the Depositary for a series of Preferred
Securities or its nominee, upon receipt of any payment of Liquidation Amount,
Redemption Price, premium or Distributions in respect of a permanent Global
Preferred Security representing any of such Preferred Securities, immediately
will credit Participants' accounts with payments in amounts proportionate to
their respective beneficial interest in the aggregate Liquidation Amount of
such Global Preferred Security for such Preferred Securities as shown on the
records of such Depositary or its nominee. The Corporation also expects that
payments by Participants to owners of beneficial interests in such Global
Preferred Security held through such Participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name."
Such payments will be the responsibility of such Participants.     
   
  Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for a series of Preferred Securities is at any time unwilling,
unable or ineligible to continue as depositary and a successor depositary is
not appointed by the Issuer within 90 days, the Issuer will issue individual
Preferred Securities of such series in exchange for the Global Preferred
Security representing such series of Preferred Securities. In addition, the
Issuer may at any time and in its sole discretion, subject to any limitations
described in the Prospectus Supplement relating to such Preferred Securities,
determine not to have any Preferred Securities of such series represented by
one or more Global Preferred Securities and, in such event, will issue
individual Preferred Securities of such series in exchange for the Global
Preferred Security or Securities representing such series of Preferred
Securities. Further, if the Issuer so specifies with respect to the Preferred
Securities of a series, an owner of a beneficial interest in a Global
Preferred Security representing Preferred Securities of such series may, on
terms acceptable to the Issuer, the Property Trustee and the Depositary for
such Global Preferred Security, receive individual Preferred Securities of
such series in exchange for such beneficial interests, subject to any
limitations described in the Prospectus Supplement relating to such Preferred
Securities. In any such instance, an owner of a beneficial interest in a
Global Preferred Security will be entitled to physical delivery of individual
Preferred Securities of the series represented by such Global Preferred
Security equal in principal amount to such beneficial interest and to have
such Preferred Securities registered in its name. Individual Preferred
Securities of such series so     
 
                                      34
<PAGE>
 
   
issued will be issued in denominations, unless otherwise specified by the
Issuer, of $25 and integral multiples thereof.     
 
PAYMENT AND PAYING AGENCY
 
  Payments in respect of the Preferred Securities shall be made to the
Depositary, which shall credit the relevant accounts at the Depositary on the
applicable Distribution Dates or, if any Issuer's Preferred Securities are not
held by the Depositary, such payments shall be made by check mailed to the
address of the holder entitled thereto as such address shall appear on the
Register. Unless otherwise specified in the applicable Prospectus Supplement,
the paying agent (the "Paying Agent") shall initially be the Property Trustee
and any co-paying agent chosen by the Property Trustee and acceptable to the
Administrative Trustees and the Corporation. The Paying Agent shall be
permitted to resign as Paying Agent upon 30 days' written notice to the
Property Trustee and the Corporation. In the event that the Property Trustee
shall no longer be the Paying Agent, the Administrative Trustees shall appoint
a successor (which shall be a bank or trust company acceptable to the
Administrative Trustees and the Corporation) to act as Paying Agent.
 
REGISTRAR AND TRANSFER AGENT
 
  Unless otherwise specified in the applicable Prospectus Supplement, the
Property Trustee will act as registrar and transfer agent for the Preferred
Securities.
 
  Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of each Issuer, but upon payment of any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The Issuers will not be required to register or cause to be
registered the transfer of their Preferred Securities after such Preferred
Securities have been called for redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
  The Property Trustee, other than during the occurrence and continuance of an
Event of Default, undertakes to perform only such duties as are specifically
set forth in each Trust Agreement and, after such Event of Default, must
exercise the same degree of care and skill as a prudent person would exercise
or use in the conduct of his or her own affairs. Subject to this provision,
the Property Trustee is under no obligation to exercise any of the powers
vested in it by the applicable Trust Agreement at the request of any holder of
Preferred Securities unless it is offered reasonable indemnity against the
costs, expenses and liabilities that might be incurred thereby. If no Event of
Default has occurred and is continuing and the Property Trustee is required to
decide between alternative causes of action, construe ambiguous provisions in
the applicable Trust Agreement or is unsure of the application of any
provision of the applicable Trust Agreement, and the matter is not one on
which holders of Preferred Securities are entitled under such Trust Agreement
to vote, then the Property Trustee shall take such action as is directed by
the Corporation and if not so directed, shall take such action as it deems
advisable and in the best interests of the holders of the Trust Securities and
will have no liability except for its own bad faith, negligence or willful
misconduct.
 
MISCELLANEOUS
   
  The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate the Issuers in such a way that no Issuer will be
deemed to be an "investment company" required to be registered under the
Investment Company Act or classified as an association taxable as a
corporation or as other than a grantor trust for United States federal income
tax purposes and so that the Corresponding Junior Subordinated Debentures will
be treated as indebtedness of the Corporation for United States federal income
tax purposes. In this connection, the Corporation and the     
 
                                      35
<PAGE>
 
Administrative Trustees are authorized to take any action, not inconsistent
with applicable law, the certificate of trust of each Issuer or each Trust
Agreement, that the Corporation and the Administrative Trustees determine in
their discretion to be necessary or desirable for such purposes, as long as
such action does not materially adversely affect the interests of the holders
of the related Preferred Securities.
 
  Holders of the Preferred Securities have no preemptive or similar rights.
 
  No Issuer may borrow money or issue debt or mortgage or pledge any of its
assets.
 
                              BOOK-ENTRY ISSUANCE
 
  DTC will act as securities depositary for all of the Preferred Securities and
the Junior Subordinated Debentures, unless otherwise referred to in the
Prospectus Supplement relating to an offering of Preferred Securities or Junior
Subordinated Debentures. The Preferred Securities and the Junior Subordinated
Debentures will be issued only as fully-registered securities registered in the
name of Cede & Co. (DTC's nominee). One or more fully-registered global
certificates will be issued for the Preferred Securities of each Issuer and the
Junior Subordinated Debentures, representing in the aggregate the total number
of such Issuer's Preferred Securities or aggregate principal balance of Junior
Subordinated Debentures, respectively, and will be deposited with DTC.
 
  DTC is a limited purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its Participants deposit with DTC. DTC also facilitates
the settlement among Participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. "Direct Participants" include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations. DTC is owned by a number of its Direct Participants and by
the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
National Association of Securities Dealers, Inc. Access to the DTC system is
also available to others such as securities brokers and dealers, banks and
trust companies that clear through or maintain custodial relationships with
Direct Participants, either directly or indirectly ("Indirect Participants").
The rules applicable to DTC and its Participants are on file with the
Commission.
   
  Purchases of Preferred Securities or Junior Subordinated Debentures within
the DTC system must be made by or through Direct Participants, which will
receive a credit for the Preferred Securities or Junior Subordinated Debentures
on DTC's records. The ownership interest of each actual purchaser of each
Preferred Security and each Junior Subordinated Debenture ("Beneficial Owner")
is in turn to be recorded on the Direct and Indirect Participants' records.
Beneficial Owners will not receive written confirmation from DTC of their
purchases, but Beneficial Owners are expected to receive written confirmations
providing details of the transactions, as well as periodic statements of their
holdings, from the Direct or Indirect Participants through which the Beneficial
Owners purchased Preferred Securities or Junior Subordinated Debentures.
Transfers of ownership interests in the Preferred Securities or Junior
Subordinated Debentures are to be accomplished by entries made on the books of
Participants acting on behalf of Beneficial Owners. Beneficial Owners will not
receive certificates representing their ownership interests in Preferred
Securities or Junior Subordinated Debentures, except in the event that use of
the book-entry system for the Preferred Securities of such Issuer or Junior
Subordinated Debentures is discontinued.     
 
  DTC has no knowledge of the actual Beneficial Owners of the Preferred
Securities or Junior Subordinated Debentures; DTC's records reflect only the
identity of the Direct Participants to whose
 
                                       36

accounts such Preferred Securities or Junior Subordinated Debentures are
credited, which may or may not be the Beneficial Owners. The Participants will
remain responsible for keeping account of their holdings on behalf of their
customers.
 
  Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners and the voting
rights of Direct Participants, Indirect Participants and Beneficial Owners
will be governed by arrangements among them, subject to any statutory or
regulatory requirements as may be in effect from time to time.
 
  Redemption notices will be sent to Cede & Co. as the registered holder of
the Preferred Securities or Junior Subordinated Debentures. If less than all
of an Issuer's Preferred Securities or the Junior Subordinated Debentures are
being redeemed, DTC's current practice is to determine by lot the amount of
the interest of each Direct Participant to be redeemed.
 
  Although voting with respect to the Preferred Securities or the Junior
Subordinated Debentures is limited to the holders of record of the Preferred
Securities or Junior Subordinated Debentures, in those instances in which a
vote is required, neither DTC nor Cede & Co. will itself consent or vote with
respect to Preferred Securities or Junior Subordinated Debentures. Under its
usual procedures, DTC would mail an omnibus proxy (the "Omnibus Proxy") to the
relevant Trustee as soon as possible after the record date. The Omnibus Proxy
assigns Cede & Co.'s consenting or voting rights to those Direct Participants
to whose accounts such Preferred Securities or Junior Subordinated Debentures
are credited on the record date (identified in a listing attached to the
Omnibus Proxy).
 
  Distribution payments on the Preferred Securities or the Junior Subordinated
Debentures will be made by the relevant Trustee to DTC. DTC's practice is to
credit Direct Participants' accounts on the relevant payment date in
accordance with their respective holdings shown on DTC's records unless DTC
has reason to believe that it will not receive payments on such payment date.
Payments by Participants to Beneficial Owners will be governed by standing
instructions and customary practices and will be the responsibility of such
Participant and not of DTC, the relevant Trustee, the Issuer thereof or the
Corporation, subject to any statutory or regulatory requirements as may be in
effect from time to time. Payment of Distributions to DTC is the
responsibility of the relevant Trustee, disbursement of such payments to
Direct Participants is the responsibility of DTC, and disbursements of such
payments to the Beneficial Owners is the responsibility of Direct and Indirect
Participants.
 
  DTC may discontinue providing its services as securities depositary with
respect to any of the Preferred Securities or the Junior Subordinated
Debentures at any time by giving reasonable notice to the relevant Trustee and
the Corporation. In the event that a successor securities depositary is not
obtained, definitive Preferred Security or Junior Subordinated Debenture
certificates representing such Preferred Securities or Junior Subordinated
Debentures are required to be printed and delivered. The Corporation, at its
option, may decide to discontinue use of the system of book-entry transfers
through DTC (or a successor depositary). After a Debenture Event of Default,
the holders of a majority in liquidation preference of Preferred Securities or
aggregate principal amount of Junior Subordinated Debentures may determine to
discontinue the system of book-entry transfers through DTC. In any such event,
definitive certificates for such Preferred Securities or Junior Subordinated
Debentures will be printed and delivered.
 
  The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Issuers and the Corporation believe to
be accurate, but the Issuers and the Corporation assume no responsibility for
the accuracy thereof. Neither the Issuers nor the Corporation has any
responsibility for the performance by DTC or its Participants of their
respective obligations as described herein or under the rules and procedures
governing their respective operations.

                           DESCRIPTION OF GUARANTEES
   
  A Guarantee will be executed and delivered by the Corporation concurrently
with the issuance by each Issuer of its Preferred Securities for the benefit
of the holders from time to time of such Preferred Securities. [Insert name of
Indenture Trustee] will act as indenture trustee ("Guarantee Trustee") under
each Guarantee for the purposes of compliance with the Trust Indenture Act and
each Guarantee will be qualified as an indenture under the Trust Indenture
Act. This summary of certain provisions of the Guarantees, which summarizes
the material terms thereof, does not purport to be complete and is subject to,
and qualified in its entirety by reference to, all of the provisions of each
Guarantee, including the definitions therein of certain terms, and the Trust
Indenture Act, to each of which reference is hereby made. The form of the
Guarantee has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part. Reference in this summary to Preferred
Securities means that Issuer's Preferred Securities to which a Guarantee
relates. The Guarantee Trustee will hold each Guarantee for the benefit of the
holders of the related Issuer's Preferred Securities.     
 
GENERAL
   
  The Corporation will irrevocably agree to pay in full on a subordinated
basis, to the extent set forth herein, the Guarantee Payments (as defined
below) to the holders of the Preferred Securities, as and when due, regardless
of any defense, right of set-off or counterclaim that such Issuer may have or
assert other than the defense of payment. The following payments with respect
to the Preferred Securities, to the extent not paid by or on behalf of the
related Issuer (the "Guarantee Payments"), will be subject to the Guarantee:
(i) any accumulated and unpaid Distributions required to be paid on such
Preferred Securities, to the extent that such Issuer has funds on hand
available therefor at such time, (ii) the Redemption Price with respect to any
Preferred Securities called for redemption, to the extent that such Issuer has
funds on hand available therefor at such time, or (iii) upon a voluntary or
involuntary dissolution, winding up or liquidation of such Issuer (unless the
Corresponding Junior Subordinated Debentures are distributed to holders of
such Preferred Securities in exchange therefor), the lesser of (a) the
Liquidation Distribution and (b) the amount of assets of such Issuer remaining
available for distribution to holders of Preferred Securities after
satisfaction of liabilities to creditors of such Issuer as required by
applicable law. The Corporation's obligation to make a Guarantee Payment may
be satisfied by direct payment of the required amounts by the Corporation to
the holders of the applicable Preferred Securities or by causing the Issuer to
pay such amounts to such holders.     
 
  Each Guarantee will be an irrevocable guarantee on a subordinated basis of
the related Issuer's obligations under the Preferred Securities, but will
apply only to the extent that such related Issuer has funds sufficient to make
such payments, and is not a guarantee of collection.
   
  If the Corporation does not make interest payments on the Corresponding
Junior Subordinated Debentures held by the Issuer, the Issuer will not be able
to pay Distributions on the Preferred Securities and will not have funds
legally available therefor. Each Guarantee will rank subordinate and junior in
right of payment to all Senior Debt of the Corporation. See "--Status of the
Guarantees." Because the Corporation is a holding company, the right of the
Corporation to participate in any distribution of assets of any subsidiary
upon such subsidiary's liquidation or reorganization or otherwise, is subject
to the prior claims of creditors of that subsidiary, except to the extent the
Corporation may itself be recognized as a creditor of that subsidiary.
Accordingly, the Corporation's obligations under the Guarantees will be
effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and claimants should look only to the assets of
the Corporation for payments thereunder. See "The Corporation." Except as
otherwise provided in the applicable Prospectus Supplement, the Guarantees do
not limit the incurrence or issuance of other secured or unsecured debt of the
Corporation, including Senior Debt, whether under the Indenture, any other
existing indenture or any other indenture that the Corporation may enter into
in the future or otherwise. See the applicable Prospectus Supplement relating
to any offering of Preferred Securities.     
 
                                      38
<PAGE>
 
   
  The Corporation has, through the applicable Guarantee, the applicable Trust
Agreement, the applicable series of Corresponding Junior Subordinated
Debentures, the Indenture and the applicable Expense Agreement, taken
together, fully, irrevocably and unconditionally guaranteed all of the
Issuer's obligations under the Preferred Securities. No single document
standing alone or operating in conjunction with fewer than all of the other
documents constitutes such guarantee. It is only the combined operation of
these documents that has the effect of providing a full, irrevocable and
unconditional guarantee of the Issuer's obligations under the Preferred
Securities. See "Relationship Among the Preferred Securities, the
Corresponding Junior Subordinated Debentures and the Guarantees."     
 
STATUS OF THE GUARANTEES
 
  Each Guarantee will constitute an unsecured obligation of the Corporation
and will rank subordinate and junior in right of payment to all Senior Debt of
the Corporation in the same manner as Junior Subordinated Debentures.
 
  Each Guarantee will rank pari passu with all other Guarantees issued by the
Corporation. Each Guarantee will constitute a guarantee of payment and not of
collection (i.e., the guaranteed party may institute a legal proceeding
directly against the Guarantor to enforce its rights under the Guarantee
without first instituting a legal proceeding against any other person or
entity). Each Guarantee will be held for the benefit of the holders of the
related Preferred Securities. Each Guarantee will not be discharged except by
payment of the Guarantee Payments in full to the extent not paid by the Issuer
or upon distribution to the holders of the Preferred Securities of the
Corresponding Junior Subordinated Debentures. None of the Guarantees places a
limitation on the amount of additional Senior Debt that may be incurred by the
Corporation. The Corporation expects from time to time to incur additional
indebtedness constituting Senior Debt.
 
AMENDMENTS AND ASSIGNMENT
   
  Except with respect to any changes which do not materially adversely affect
the rights of holders of the related Preferred Securities (in which case no
vote will be required), no Guarantee may be amended without the prior approval
of the holders of not less than a majority of the aggregate Liquidation Amount
of such outstanding Preferred Securities. The manner of obtaining any such
approval will be as set forth under "Description of Preferred Securities--
Voting Rights; Amendment of Each Trust Agreement." All guarantees and
agreements contained in each Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Corporation and shall inure to
the benefit of the holders of the related Preferred Securities then
outstanding.     
 
EVENTS OF DEFAULT
 
  An event of default under each Guarantee will occur upon the failure of the
Corporation to perform any of its payment or other obligations thereunder. The
holders of not less than a majority in aggregate Liquidation Amount of the
related Preferred Securities have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Guarantee
Trustee in respect of such Guarantee or to direct the exercise of any trust or
power conferred upon the Guarantee Trustee under such Guarantee.
 
  Any holder of the Preferred Securities may institute a legal proceeding
directly against the Corporation to enforce its rights under such Guarantee
without first instituting a legal proceeding against the Issuer, the Guarantee
Trustee or any other person or entity.
 
  The Corporation, as guarantor, is required to file annually with the
Guarantee Trustee a certificate as to whether or not the Corporation is in
compliance with all the conditions and covenants applicable to it under the
Guarantee.
 
                                      39

INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
  The Guarantee Trustee, other than during the occurrence and continuance of a
default by the Corporation in performance of any Guarantee, undertakes to
perform only such duties as are specifically set forth in each Guarantee and,
after default with respect to any Guarantee, must exercise the same degree of
care and skill as a prudent person would exercise or use in the conduct of his
or her own affairs. Subject to this provision, the Guarantee Trustee is under
no obligation to exercise any of the powers vested in it by any Guarantee at
the request of any holder of any Preferred Securities unless it is offered
reasonable indemnity against the costs, expenses and liabilities that might be
incurred thereby.
 
TERMINATION OF THE GUARANTEES
   
  Each Guarantee will terminate and be of no further force and effect upon
full payment of the Redemption Price of the related Preferred Securities, upon
full payment of the amounts payable upon liquidation of the related Issuer or
upon distribution of Corresponding Junior Subordinated Debentures to the
holders of the related Preferred Securities in exchange therefor. Each
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any holder of the related Preferred Securities must restore
payment of any sums paid under such Preferred Securities or such Guarantee.
    
GOVERNING LAW
 
  Each Guarantee will be governed by and construed in accordance with the laws
of the State of New York.
 
THE EXPENSE AGREEMENT
   
  Pursuant to the Expense Agreement entered into by the Corporation under each
Trust Agreement (the "Expense Agreement"), the Corporation will, as holder of
the Common Securities, irrevocably and unconditionally guarantee to each
Person to whom the Issuer becomes indebted or liable, the full payment of any
costs, expenses or liabilities of the Issuer, other than obligations of the
Issuer to pay to the holders of any Preferred Securities or other similar
interests in the Issuer of the amounts due such holders pursuant to the terms
of the Preferred Securities or such other similar interests, as the case may
be. The Expense Agreement will be enforceable by third parties.     
       
     RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE CORRESPONDING JUNIOR
    SUBORDINATED DEBENTURES, THE EXPENSE AGREEMENT AND THE GUARANTEES     
 
FULL AND UNCONDITIONAL GUARANTEE
   
  Payments of Distributions and other amounts due on the Preferred Securities
(to the extent the Issuer has funds available for the payment of such
Distributions) are irrevocably guaranteed by the Corporation as and to the
extent set forth under "Description of Guarantees." Taken together, the
Corporation's obligations under each series of Corresponding Junior
Subordinated Debentures, the Indenture, the related Trust Agreement, the
related Expense Agreement, and the related Guarantee provide, in the
aggregate, a full, irrevocable and unconditional guarantee of payments of
distributions and other amounts due on the Related Preferred Securities. No
single document standing alone or operating in conjunction with fewer than all
of the other documents constitutes such guarantee. It is only the combined
operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the Issuer's obligations under the
Related Preferred Securities. If and to the     
 
                                      40
<PAGE>
 
   
extent that the Corporation does not make payments on any series of
Corresponding Junior Subordinated Debentures, such Issuer will not pay
Distributions or other amounts due on the Related Preferred Securities. The
Guarantees do not cover payment of Distributions when the related Issuer does
not have sufficient funds to pay such Distributions. In such event, the remedy
of a holder of a series of Preferred Securities is to institute a legal
proceeding directly against the Corporation pursuant to the terms of the
Indenture for enforcement of payment of amounts equal to such Distributions to
such holder. The obligations of the Corporation under each Guarantee are
subordinate and junior in right of payment to all Senior Debt of the
Corporation.     
 
SUFFICIENCY OF PAYMENTS
   
  As long as payments of interest and other payments are made when due on each
series of Corresponding Junior Subordinated Debentures, such payments will be
sufficient to cover Distributions and other payments due on the Related
Preferred Securities, primarily because (i) the aggregate principal amount of
each series of Corresponding Junior Subordinated Debentures will be equal to
the sum of the aggregate stated Liquidation Amount of the Related Preferred
Securities and related Common Securities; (ii) the interest rate and interest
and other payment dates on each series of Corresponding Junior Subordinated
Debentures will match the Distribution rate and Distribution and other payment
dates for the Related Preferred Securities; (iii) the Corporation shall pay
for all and any costs, expenses and liabilities of such Issuer except the
Issuer's obligations to holders of its Preferred Securities under such
Preferred Securities; and (iv) each Trust Agreement further provides that the
Issuer will not engage in any activity that is not consistent with the limited
purposes of such Issuer.     
 
  Notwithstanding anything to the contrary in the Indenture, the Corporation
has the right to set-off any payment it is otherwise required to make
thereunder with and to the extent the Corporation has theretofore made, or is
concurrently on the date of such payment making, a payment under the related
Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES
 
  A holder of any related Preferred Security may institute a legal proceeding
directly against the Corporation to enforce its rights under the related
Guarantee without first instituting a legal proceeding against the Guarantee
Trustee, the related Issuer or any other person or entity.
   
  A default or event of default under any Senior Debt of the Corporation would
not constitute a default or Event of Default under the Indenture. However, in
the event of payment defaults under, or acceleration of, Senior Debt of the
Corporation, the subordination provisions of the Indenture provide that no
payments may be made in respect of the Corresponding Junior Subordinated
Debentures until such Senior Debt has been paid in full or any payment default
thereunder has been cured or waived. Failure to make required payments on any
series of Corresponding Junior Subordinated Debentures would constitute an
Event of Default under the Indenture.     
 
LIMITED PURPOSE OF ISSUERS
 
  Each Issuer's Preferred Securities evidence a beneficial interest in such
Issuer, and each Issuer exists for the sole purpose of issuing its Preferred
Securities and Common Securities and investing the proceeds thereof in
Corresponding Junior Subordinated Debentures. A principal difference between
the rights of a holder of a Preferred Security and a holder of a Corresponding
Junior Subordinated Debenture is that a holder of a Corresponding Junior
Subordinated Debenture is entitled to receive from the Corporation the
principal amount of and interest accrued on Corresponding Junior Subordinated
Debentures held, while a holder of Preferred Securities is entitled to receive
Distributions from such Issuer (or from the Corporation under the applicable
Guarantee) if and to the extent such Issuer has funds available for the
payment of such Distributions.
 
                                      41
<PAGE>
 
RIGHTS UPON TERMINATION
   
  Upon any voluntary or involuntary termination, winding-up or liquidation of
any Issuer involving the liquidation of the Corresponding Junior Subordinated
Debentures, the holders of the related Preferred Securities will be entitled
to receive, out of the assets held by such Issuer, the Liquidation
Distribution in cash. See "Description of Preferred Securities--Liquidation
Distribution Upon Termination." Upon any voluntary or involuntary liquidation
or bankruptcy of the Corporation, the Property Trustee, as holder of the
Corresponding Junior Subordinated Debentures, would be a subordinated creditor
of the Corporation, subordinated in right of payment to all Senior Debt as set
forth in the Indenture, but entitled to receive payment in full of principal
and interest, before any stockholders of the Corporation receive payments or
distributions. Since the Corporation is the guarantor under each Guarantee and
has agreed to pay for all costs, expenses and liabilities of each Issuer
(other than the Issuer's obligations to the holders of its Preferred
Securities), the positions of a holder of such Preferred Securities and a
holder of such Corresponding Junior Subordinated Debentures relative to other
creditors and to stockholders of the Corporation in the event of liquidation
or bankruptcy of the Corporation are expected to be substantially the same.
    
                             PLAN OF DISTRIBUTION
   
  The Junior Subordinated Debentures or the Preferred Securities may be sold
in a public offering to or through underwriters or dealers designated from
time to time. The Corporation and each Issuer may sell its Junior Subordinated
Debentures or Preferred Securities as soon as practicable after effectiveness
of the Registration Statement of which this Prospectus forms a part. The names
of any underwriters or dealers involved in the sale of the Junior Subordinated
Debentures or Preferred Securities in respect of which this Prospectus is
delivered, the amount or number of Junior Subordinated Debentures and
Preferred Securities to be purchased by any such underwriters and any
applicable commissions or discounts will be set forth in the applicable
Prospectus Supplement.     
 
  Underwriters may offer and sell Junior Subordinated Debentures or Preferred
Securities at a fixed price or prices, which may be changed, or from time to
time at market prices prevailing at the time of sale, at prices related to
such prevailing market prices or at negotiated prices. In connection with the
sale of Preferred Securities, underwriters may be deemed to have received
compensation from the Corporation and/or the applicable Issuer in the form of
underwriting discounts or commissions and may also receive commissions.
Underwriters may sell Junior Subordinated Debentures or Preferred Securities
to or through dealers, and such dealers may receive compensation in the form
of discounts, concessions or commissions from the underwriters.
   
  Any underwriting compensation paid by the Corporation and/or the applicable
Issuer to underwriters in connection with the offering of Junior Subordinated
Debentures or Preferred Securities, and any discounts, concessions or
commissions allowed by such underwriters to participating dealers, will be
described in an accompanying Prospectus Supplement. Underwriters and dealers
participating in the distribution of Junior Subordinated Debentures or
Preferred Securities may be deemed to be underwriters, and any discounts and
commissions received by them and any profit realized by them on resale of such
Junior Subordinated Debentures or Preferred Securities may be deemed to be
underwriting discounts and commissions, under the Securities Act. Underwriters
and dealers may be entitled, under agreement with the Corporation and the
applicable Issuer, to indemnification against and contribution toward certain
civil liabilities, including liabilities under the Securities Act, and to
reimbursement by the Corporation for certain expenses.     
   
  In connection with the offering of the Preferred Securities of any Issuer,
such Issuer may grant to the underwriters an option to purchase additional
Preferred Securities to cover over-allotments, if any, at the initial public
offering price (with an additional underwriting commission), as may be set
forth in     
 
                                      42
<PAGE>
 
   
the accompanying Prospectus Supplement. If such Issuer grants any over-
allotment option, the terms of such over-allotment option will be set forth in
the Prospectus Supplement for such Preferred Securities.     
 
  Underwriters and dealers may engage in transactions with, or perform
services for, the Corporation and/or the applicable Issuer and/or any of their
affiliates in the ordinary course of business.
 
  The Junior Subordinated Debentures and the Preferred Securities will be new
issues of securities and will have no established trading market. Any
underwriters to whom Junior Subordinated Debentures or Preferred Securities
are sold for public offering and sale may make a market in such Junior
Subordinated Debentures and Preferred Securities, but such underwriters will
not be obligated to do so and may discontinue any market making at any time
without notice. Such Junior Subordinated Debentures or Preferred Securities
may or may not be listed on a national securities exchange or the Nasdaq
National Market. No assurance can be given as to the liquidity of or the
existence of trading markets for any Junior Subordinated Debentures or
Preferred Securities.
 
                            VALIDITY OF SECURITIES
   
  Unless otherwise indicated in the applicable Prospectus Supplement, certain
matters of Delaware law relating to the validity of the Preferred Securities,
the enforceability of the Trust Agreements and the formation of the Issuers
will be passed upon by Richards, Layton & Finger, One Rodney Square,
Wilmington, Delaware 19801, special Delaware counsel to the Corporation and
the Issuers. Unless otherwise indicated in the applicable Prospectus
Supplement, the validity of the Guarantees and the Junior Subordinated
Debentures will be passed upon for the Corporation by Carl Krasik, Esq.,
Associate General Counsel and Secretary of the Corporation, One Mellon Bank
Center, Pittsburgh, Pennsylvania 15258, and for the Underwriters by Sullivan &
Cromwell, 125 Broad Street, New York, New York 10004. Mr. Krasik and Sullivan
& Cromwell will rely on the opinion of Richards, Layton & Finger as to matters
of Delaware law, and Sullivan & Cromwell will rely on the opinion of Mr.
Krasik as to matters of Pennsylvania law. Certain matters relating to United
States federal income tax considerations will be passed upon for the
Corporation by Sullivan & Cromwell, as special tax counsel for the
Corporation. Sullivan & Cromwell from time to time performs legal services for
the Corporation. At September 30, 1996, Mr. Krasik held options covering 5,950
shares of the Corporation's Common Stock.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Restated Articles of Incorporation, as amended, of the Corporation (the
"Articles") provide that, except as prohibited by law, every director and
officer of the Corporation shall be entitled as of right to be indemnified by
the Corporation against expenses and any liability paid or incurred by such
person in connection with any actual or threatened claim, action, suit or
proceeding, civil, criminal, administrative, investigative or other, whether
brought by or in the right of the Corporation or otherwise, in which such
person may be involved (subject to certain limitations in the case of actions
by such person against the Corporation) by reason of such person being or
having been a director or officer of the Corporation or serving or having
served at the request of the Corporation as a director, officer, employee,
fiduciary or other representative of another entity. The Articles also give to
indemnitees the right to have their expenses in defending such actions paid in
advance by the Corporation, subject to any obligation imposed by law or
otherwise to reimburse the Corporation in certain events. The Corporation has
entered into an indemnity agreement (the "Indemnity Agreement") with each
director and certain of its officers which provides a contractual right to
indemnification against such expenses and liabilities (subject to certain
limitations and exceptions) and a contractual right to advancement of expenses
and contains additional provisions regarding determination of entitlement,
defense of claims, rights of contribution and other matters.
 
  The Pennsylvania Business Corporation Law permits a corporation to indemnify
its directors and officers, and to pay their expenses in advance, subject to
certain limitations and exceptions. The specific indemnity provisions, which
are by their terms not intended to be exclusive, are, in general, not as broad
as the provisions of the Articles and the Indemnity Agreement; however, one
provision would preclude indemnification in any case where the act or failure
to act giving rise to the claim for indemnification is determined by a court
to have constituted willful misconduct or recklessness, and another provision
requires that advances of expenses may be made by a corporation only upon
receipt of an undertaking to repay such amount if it shall ultimately be
determined that such person is not entitled to be indemnified by the
corporation.
 
 
                                     II-1

  The Corporation has purchased liability insurance policies covering its
directors and officers to insure against claims arising out of certain alleged
wrongful acts on the part of such directors and officers and against claims
arising out of certain alleged breaches of fiduciary duty under the Employee
Retirement Income Security Act of 1974 on the part of such directors and
officers.
 
  Article Seventh of the Articles and Article Two of the Corporation's By-
Laws, as amended, both adopted by the shareholders of the Corporation at their
annual meeting on April 20, 1987, further provide that, to the fullest extent
that the laws of Pennsylvania, as in effect on January 27, 1987 or as
thereafter amended, permit elimination or limitation of the liability of
directors, no director of the Corporation shall be personally liable for
monetary damages as such for any action taken, or any failure to take any
action, as a director. The Pennsylvania Business Corporation Law provides that
whenever the by-laws of a corporation by a vote of the shareholders so
provide, a director shall not be personally liable for monetary damages as
such for any action taken, or failure to take any action, unless (i) the
director has breached or failed to perform the duties of his office under the
standard of care and justifiable reliance specified in the Act and (ii) the
breach or failure to perform constitutes self-dealing, willful misconduct or
recklessness. These provisions do not apply to (i) responsibility or liability
of a director pursuant to any criminal statute or (ii) the liability of a
director for payment of taxes.
   
  Reference is made to the Underwriting Agreement, the form of which is filed
as Exhibit 1 to this Registration Statement.     
   
  Under the Trust Agreement, the Corporation will agree to indemnify each of
the Trustees of the Issuer or any predecessor Trustee for the Issuer, and to
hold the Trustee harmless against, any loss, damage, claims, liability or
expense incurred without negligence or bad faith on its part, arising out of
or in connection with the acceptance or administration of the Trust
Agreements, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of
its powers or duties under the Trust Agreements.

ITEM 17. UNDERTAKING
 
 (a) Rule 415 Offering.
   
  Each of the undersigned Registrants hereby undertakes:     
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement:
       
      (i) To include any prospectus required by Section 10(a) (3) of the
    Securities Act of 1933, unless the information required to be included
    in such post-effective amendment is contained in a periodic report filed
    by the Registrants pursuant to Section 13 or Section 15(d) of the
    Securities Exchange Act of 1934 and incorporated herein by reference;
           
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement unless the information required to be
    included in such post-effective amendment is contained in a periodic
    report filed with or furnished to the Commission by Registrants pursuant
    to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
    and incorporated herein by reference. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculated
    Registration Fee" table in the effective registration statement.     
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
     
    (4) To provide to the underwriter at the closing specified in the
  underwriting agreement certificates in such denominations and registered in
  such names as required by the underwriter to permit prompt delivery to each
  purchaser.     
     
    (5) That, for the purposes of determining any liability under the
  Securities Act of 1933:     
       
      (i) The information omitted from the form of prospectus filed as part
    of this Registration Statement in reliance upon Rule 430A and contained
    in the form of prospectus filed by the Registrants pursuant to Rule
    424(b)(1) or (4) or 487(h) under the Securities Act shall be deemed to
    be part of this Registration Statement as of the time it was declared
    effective.     
       
      (ii) Each post-effective amendment that contains a form of prospectus
    shall be deemed to be a new Registration Statement relating to the
    securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.     
 
 (b) Filings Incorporating Subsequent Exchange Act Documents by Reference.
   
  Each of the undersigned Registrants hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of a
Registrant's Annual Report pursuant to     
 
                                     II-4
<PAGE>
 
Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
 (c) Acceleration of Effectiveness.
   
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of
each Registrant pursuant to the provisions described in Item 15 above, or
otherwise, each Registrant has been advised that in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by each Registrant of expenses incurred or paid by a director, officer
or controlling person of each Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, each
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.

premises and the purchase of the Securities by the Holders thereof, it is
mutually covenanted and agreed, for the equal and proportionate benefit of all
Holders of the Securities or of any series thereof, as follows:

trustee in respect of, other indebtedness that is subordinate and junior in
right of payment to such Senior Debt pursuant to any provision of such

determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date, provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 1.6.

  The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(2) or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such
series. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities of such series on such record date, and no other Holders,
shall be entitled to join in such notice, declaration, request or direction,
whether or not such Holders remain Holders after such record date, provided that
no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by 

                                       12
<PAGE>
 
Holders and the applicable Expiration Date to be given to the Company in
writing and to each Holder of Securities of the relevant series in the manner
set forth in Section 1.6.

  With respect to any record date set pursuant to this Section, the party hereto
which sets such record dates may designate any day as the "Expiration Date" and
from time to time may change the Expiration Date to any earlier or later day,
provided that no such change shall be effective unless notice of the proposed
new Expiration Date is given to the other party hereto in writing, and to each
Holder of Securities of the relevant series in the manner set forth in Section
10.6, on or prior to the existing Expiration Date. If an Expiration Date is not
designated with respect to any record date set pursuant to this Section, the
party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

  (g) Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

of Holders or other document provided or permitted by this Indenture to be made
upon, given or furnished to, or filed with,

  (1) the Trustee by any Holder, any holder of Preferred Securities or the
Company shall be sufficient for every purpose hereunder if made, given,

writing and mailed, first class postage prepaid, to each Holder affected by such
event, at the address of such Holder as it appears in the Securities Register,
not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, 

                                       13
<PAGE>
 
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

compounded quarterly. The amount of interest payable for any period shall be
computed on the basis of twelve 30-day months and a 360-day year. The amount of
interest payable for any partial period shall be computed on the basis of the
number of days elapsed in a 360-day year of twelve 30-day months. In the event
that any date on which interest is payable on this Security is not a Business
Day, then a payment of the interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on the date the payment was originally payable. A "Business Day"
shall mean any day other than (i) a Saturday or Sunday, (ii) a day on which
banking institutions in The City of New York are authorized or required by law
or executive order to remain closed or (iii) a day on which the Corporate Trust
Office of the Trustee, or the principal office of the Property Trustee under
the Trust Agreement hereinafter referred to for Mellon Capital I, is closed for
business. The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person  in whose name this Security (or one or more Predecessor
Securities is registered at the close of business on the Regular Record Date
for such interest installment, which shall be the March 15, June 15, September
15 and December 15 next preceding the applicable Interest Payment Date. Any
such interest installment not so punctually paid or duly provided for shall
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person 

                                       16
<PAGE>
 
in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture.

  So long as no Event of Default has occurred and is continuing, the Company
shall have the right at any time during the term of this Security to defer
payment of interest on this Security, at any time or from time to time, for up
to twenty consecutive quarterly interest payment periods with respect to each
deferral period (each an "Extension Period"), during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest thereon to
the extent permitted by applicable law); provided, however, that no Extension
Period shall extend beyond the Stated Maturity of the principal of this
Security; provided, further, that during any such Extension Period, the Company
shall not, and shall not permit any Subsidiary of the Company to, (i) declare or
pay any dividends or distributions or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company's capital stock or (ii)
make any payment of principal of or interest or premium, if any, on or repay,
repurchase or redeem any debt security of the Company that ranks pari passu with
or junior in interest to this Security or make any guarantee payments with
respect to any guarantee by the Company of the debt securities of any
Subsidiaries of the Company if such guarantee ranks pari passu with or junior in
interest to this Security (other than (a) dividends or distributions in Common
Stock, (b) any declaration of a dividend in connection with the implementation
of a Rights Plan, the issuance of any Common Stock or any class or series of
preferred stock of the Company under any Rights Plan or the repurchase of any
rights distributed pursuant to a Rights Plan, (c) payments under any Mellon
Guarantee, and (d) purchases of Common Stock related to the issuance of Common
Stock under any of the Company's benefit plans for its directors, officers or
employees, related to the issuance of common stock or rights under a dividend
reinvestment and stock purchase plan, or related to the issuance of common
stock (or securities convertible into or exchangeable for common stock) as
consideration in an acquisition transaction. Prior to the termination of any
such Extension Period, the Company may further extend the interest payment
period, provided that no Extension Period shall exceed twenty consecutive
quarters or extend beyond the Stated Maturity of the principal of this
Security. Upon the termination of any such Extension Period and upon the
payment of all accrued and unpaid interest and any Additional Interest then
due, the Company may elect to begin a new Extension Period, subject to the
above requirements. No interest shall be due and payable during an Extension
Period except at the end thereof. The Company shall give the Holder of this
Security and the Trustee notice of its election to begin any Extension Period
at least one Business Day prior to the next succeeding Interest Payment Date on
which interest on this Security would be payable but for such deferral or, with
respect to the Securities issued to a Mellon Trust, so long as such Securities
are held by such Mellon Trust, prior to the earlier of (i) the next succeeding
date on which Distributions on the Preferred 

                                       17
<PAGE>
 
Securities would be payable but for such deferral or (ii) the date the
Administrative Trustees are required to give notice to any securities exchange
or other applicable self-regulatory organization or to holders of such
Preferred Securities of the record date or the date such Distributions are
payable, but in any event not less than one Business Day prior to such record
date.

  Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in the United States, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made (i) by check mailed to the address of the Person entitled
thereto as such address shall appear in the Securities Register or (ii) by wire
transfer in immediately available funds at such place and to such account as may
be designated by the Person entitled thereto as specified in the Securities
Register.

  The indebtedness evidenced by this Security is, to the extent provided in the
Indenture, subordinate and subject in right of payments to the prior payment in
full of all Senior Debt, and this Security is issued subject to the provisions
of the Indenture with respect thereto. Each Holder of this Security, by
accepting the same, (a) agrees to and shall be bound by such provisions, (b)
authorizes and directs the Trustee on his behalf to take such actions as may be
necessary or appropriate to effectuate the subordination so provided and (c)
appoints the Trustee his attorney-in-fact for any and all such purposes. Each
Holder hereof, by his acceptance hereof, waives all notice of the acceptance of
the subordination provisions contained herein and in the Indenture by each
holder of Senior Debt, whether now outstanding or hereafter incurred, and waives
reliance by each such holder upon said provisions.

  Reference is hereby made to the further provisions of this Security set forth
on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

  Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

  IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed
under its corporate seal.

     Section 2.3.   Form of Reverse of Security.

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under a Junior Subordinated Indenture, dated as of December __, 1996
(herein called the "Indenture"), between the Company and The Chase Manhattan
Bank, as Trustee (herein called the "Trustee", which term includes any successor
trustee under the Indenture), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Trustee, the
Company and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof, limited in aggregate principal
amount to $            .

     All terms used in this Security that are defined in the Indenture or in the
Amended and Restated Trust Agreement, dated as of December __, 1996, as amended
(the "Trust Agreement"), for Mellon Capital I, among Mellon Bank Corporation, as
Depositor, and the Trustees named therein, shall have the meanings assigned to
them in the Indenture or the Trust Agreement, as the case may be.

     The Company may at any time, at its option, on or after December __, 2001,
and subject to the terms and conditions of Article XI of the Indenture, redeem
this Security in whole at any time or in part from time to time, without premium
or penalty, at a redemption price equal to 100% of the principal amount thereof
plus accrued and unpaid interest, including Additional Interest, if any, to the
Redemption Date.

     Upon the occurrence and during the continuation of a Tax Event or a Capital
Treatment Event in respect of a Mellon Trust, the Company may, at its option, at
any time within 90 days of the occurrence of such Tax Event or Capital Treatment
Event redeem this Security, in whole but not in part, subject to the provisions
of Section 11.7 and the other provisions of Article XI of the Indenture, at a
redemption price equal to 100% of the principal amount thereof plus accrued and
unpaid interest, including Additional Interest, if any, to the Redemption Date.

     In the event of redemption of this Security in part only, a new Security or
Securities of this series for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

     The Indenture contains provisions for satisfaction and discharge of the
entire indebtedness of this Security upon compliance by the Company with certain
conditions set forth in the Indenture.

                                       19

     The Indenture permits, with certain exceptions as therein provided, the
Company and the Trustee at any time to enter into a supplemental indenture or
indentures for the purpose of modifying in any manner the rights and obligations
of the Company and of the Holders of the Securities, with the consent of the
Holders of not less than a majority in principal amount of the Outstanding
Securities of each series to be affected by such supplemental indenture. The
Indenture also contains provisions permitting Holders of specified percentages
in principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

     [If the Security is not a Discount Security,--As provided in and subject to
the provisions of the Indenture, if an Event of Default with respect to the
Securities of this series at the time Outstanding occurs and is continuing, then
and in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of this series may declare the
principal amount of all the Securities of this series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), provided that, in the case of the Securities of this series issued
to a Mellon Trust, if upon an Event of Default, the Trustee or the Holders of
not less than 25% in principal amount of the Outstanding Securities of this
series fails to declare the principal of all the Securities of this series to be
immediately due and payable, the holders of at least 25% in aggregate
Liquidation Amount of the Preferred Securities then outstanding shall have such
right by a notice in writing to the Company and the Trustee; and upon any such
declaration the principal amount of and the accrued interest (including any
Additional Interest) on all the Securities of this series shall become
immediately due and payable, provided that the payment of principal and
interest (including any Additional Interest) on such Securities shall remain
subordinated to the extent provided in Article XIII of the Indenture.]

     [If the Security is a Discount Security,--As provided in and subject to the
provisions of the Indenture, if an Event of Default with respect to the
Securities of this series at the time Outstanding occurs and is continuing, then
and in every such case the Trustee or the Holders of not less than such portion
of the principal amount as may be specified in the terms of this series may
declare an amount of principal of the Securities of this series to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), provided that, in the case of the Securities of this
series issued to a Mellon Trust, if upon an Event of Default, the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of this series fails to declare the principal of all the Securities of this
series to be immediately due and payable, the holders of at least 25% in
aggregate Liquidation Amount of the Preferred Securities then outstanding shall
have such right by a notice in writing to the Company and the Trustee.  Such
amount shall be equal to--insert formula for determining the amount. Upon any
such declaration, such amount of the principal of and the accrued interest
(including any Additional Interest) on all the 

                                       20
<PAGE>
 
Securities of this series shall become immediately due and payable, provided
that the payment of principal and interest (including any Additional Interest)
on such Securities shall remain subordinated to the extent provided in Article
XIII of the Indenture. Upon payment (i) of the amount of principal so declared
due and payable and (ii) of interest on any overdue principal and overdue
interest (in each case to the extent that the payment of such interest shall be
legally enforceable), all of the Company's obligations in respect of the
payment of the principal of and interest, if any, on this Security shall
terminate.]

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Securities Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company maintained under Section 10.2 of the Indenture duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Securities Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $25 and any integral multiple thereof. As provided
in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of such series of a different authorized denomination, as
requested by the Holder surrendering the same.

     The Company and, by its acceptance of this Security or a beneficial
interest therein, the Holder of, and any Person that acquires a beneficial
interest in, this Security agree that for United States Federal, state and local
tax purposes it is intended that this Security constitute indebtedness.

     THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF
LAWS PRINCIPLES THEREOF.

   The Securities shall be executed on behalf of the Company by its President or

thereon and attested by its Secretary or one of its Assistant Secretaries. The
signature of any of these officers on the Securities may be manual or
facsimile.

   Securities bearing the manual or facsimile signatures of individuals who were
at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities. At any time and from time to
time after the execution and delivery of this Indenture, the Company may deliver
Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities. If the form or terms of
the Securities of the series have been established by or pursuant to one or more
Board Resolutions as permitted by Sections 2.1 and 3.1, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 6.1) shall be fully protected in relying upon, an Opinion of
Counsel stating,

 (1) if the form of such Securities has been established by or pursuant to Board
Resolution as permitted by Section 2.1, that such form has been established in
conformity with the provisions of this Indenture;

 (2) if the terms of such Securities have been established by or pursuant to
Board Resolution as permitted by Section 3.1, that such terms have been
established in conformity with the provisions of this Indenture; and

 (3) that such Securities, when authenticated and delivered by the Trustee and
issued by the Company in the manner and subject to any conditions specified in
such Opinion of Counsel, will constitute valid and legally binding obligations
of the Company enforceable in accordance with their terms, subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.

                                       25
<PAGE>
 
If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

       Notwithstanding the provisions of Section 3.1 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.1 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

   Each Security shall be dated the date of its authentication.

   No Security shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
officers, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder. Notwithstanding the foregoing, if any Security shall have
been authenticated and delivered hereunder but never issued and sold by the
Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 3.9, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

   Section 3.4.   Temporary Securities.

   Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any denomination, substantially of the tenor of the
definitive Securities of such series in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

   If temporary Securities of any series are issued, the Company will cause
definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of definitive Securities, the temporary Securities shall
be exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for that purpose
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more definitive Securities
of the same series, of any authorized denominations having the same Original
Issue Date and Stated Maturity and having the same terms as such temporary
Securities. Until so exchanged, the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

   Section 3.5.   Registration, Transfer and Exchange.

                                       26
<PAGE>
 
   The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities. Such register is herein sometimes referred to as the
"Securities Register." The Trustee is hereby appointed "Securities Registrar"
for the purpose of registering Securities and transfers of Securities as herein
provided.

   Upon surrender for registration of transfer of any Security at the office or
agency of the Company designated for that purpose the Company shall execute, and
the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of the same series of any
authorized denominations, of a like aggregate principal amount, of the same
Original Issue Date and Stated Maturity and having the same terms.

                                       27
<PAGE>
 
   At the option of the Holder, Securities may be exchanged for other Securities
of the same series of any authorized denominations, of a like aggregate
principal amount, of the same Original Issue Date and Stated Maturity and having
the same terms, upon surrender of the Securities to be exchanged at such office
or agency. Whenever any securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

   All Securities issued upon any transfer or exchange of Securities shall be
the valid obligations of the Company, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.

   Every Security presented or surrendered for transfer or exchange shall (if so
required by the Company or the Securities Registrar) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing.

   No service charge shall be made to a Holder for any transfer or exchange of
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any
transfer or exchange of Securities.

   The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:

 (1) Each Global Security authenticated under this Indenture shall be registered
in the name of the Depositary designated for such Global Security or a nominee
thereof and delivered to such Depositary or a nominee thereof or custodian
therefor, and each such Global Security shall constitute a single Security for
all purposes of this Indenture.

 (2) Notwithstanding any other provision in this Indenture, no Global Security
may be exchanged in whole or in part for Securities registered, and no transfer
of a Global Security in whole or in part may be registered, in the name of any
Person other than the Depositary for such Global Security or a nominee thereof
unless (A) such Depositary (i) has notified the Company that it is unwilling or
unable to continue as Depositary for such Global Security or (ii) has ceased to

                                       28
<PAGE>
 
be a clearing agency registered under the Exchange Act at a time when the
Depositary is required to be so registered to act as depositary, in each case
unless the Company has approved a successor Depositary within 90 days, (B) there
shall have occurred and be continuing an Event of Default with respect to such
Global Security, (C) the Company in its sole discretion determines that such
Global Security will be so exchangeable or transferable or (D) there shall exist
such circumstances, if any, in addition to or in lieu of the foregoing as have
been specified for this purpose as contemplated by Section 3.1.

  (3) Subject to Clause (2) above, any exchange of a Global Security for other
Securities may be made in whole or in part, and all Securities issued in
exchange for a Global Security or any portion thereof shall be registered in
such names as the Depositary for such Global Security shall direct.

  (4) Every Security authenticated and delivered upon registration of transfer
of, or in exchange for or in lieu of, a Global Security or any portion thereof,
whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.6 or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof.

   Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, transfer or exchange any Security of
any series during a period beginning at the opening of business 15 days before
the day of selection for redemption of Securities pursuant to Article XI and
ending at the close of business on the day of mailing of notice of redemption or
(b) to transfer or exchange any Security so selected for redemption in whole or
in part, except, in the case of any Security to be redeemed in part, any portion
thereof not to be redeemed.

   Section 3.6.   Mutilated, Destroyed, Lost and Stolen Securities.

   If any mutilated Security is surrendered to the Trustee together with such
security or indemnity as may be required by the Company or the Trustee to save
each of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same issue
and series of like tenor and principal amount, having the same Original Issue
Date and Stated Maturity, and bearing a number not contemporaneously
outstanding.

   If there shall be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security, and (ii)
such security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Company or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and upon its request the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of the same issue and
series of like tenor and principal amount, having the same Original Issue Date
and Stated Maturity as such destroyed, lost or stolen Security, and bearing a
number not contemporaneously outstanding.

                                       29
<PAGE>
 
   In case any such mutilated, destroyed, lost or stolen Security has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, pay such Security.

   Upon the issuance of any new Security under this Section, 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 Trustee) connected therewith.

   Every new Security issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Securities duly issued hereunder.



   The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

   Section 3.7.   Payment of Interest; Interest Rights Preserved.

   Interest on any Security of any series which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date, shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such interest
in respect of Securities of such series, except that, unless otherwise provided
in the Securities of such series, interest payable on the Stated Maturity of the
principal of a Security shall be paid to the Person to whom principal is paid.
The initial payment of interest on any Security of any series which is issued
between a Regular Record Date and the related Interest Payment Date shall be
payable as provided in such Security or in the Board Resolution pursuant to
Section 3.1 with respect to the related series of Securities.

   Any interest on any Security which is payable, but is not timely paid or duly
provided for, on any Interest Payment Date for Securities of such series (herein
called "Defaulted Interest"), shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having been
such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

  (1) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities of such series in respect of which
interest is in default (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security and the date of the proposed payment, and
at the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit 

                                       30
<PAGE>
 
of the Persons entitled to such Defaulted Interest as in this Clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company of such Special Record Date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor to be mailed,
first class, postage prepaid, to each Holder of a Security of such series at
the address of such Holder as it appears in the Securities Register not less
than 10 days prior to such Special Record Date. The Trustee may, in its
discretion, in the name and at the expense of the Company, cause a similar
notice to be published at least once in a newspaper, customarily published in
the English language on each Business Day and of general circulation in the
Borough of Manhattan, The City of New York, but such publication shall not be a
condition precedent to the establishment of such Special Record Date. Notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been mailed as aforesaid, such Defaulted Interest shall be paid
to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered on such Special Record Date
and shall no longer be payable pursuant to the following Clause (2).

  (2) The Company may make payment of any Defaulted Interest in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Securities of the series in respect of which interest is in default
may be listed and, upon such notice as may be required by such exchange (or by
the Trustee if the Securities are not listed), if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this Clause, such
payment shall be deemed practicable by the Trustee.

   Subject to the foregoing provisions of this Section, each Security delivered
under this Indenture upon transfer of or in exchange for or in lieu of any other
Security shall carry the rights to interest accrued and unpaid, and to accrue,
which were carried by such other Security.

   Section 3.8.   Persons Deemed Owners.

   The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name any Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 3.7) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

   Section 3.9.   Cancellation.

   All Securities surrendered for payment, redemption, transfer or exchange
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee, and any such Securities and Securities surrendered directly to the
Trustee for any such purpose shall be promptly canceled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee. No Securities 

                                       31
<PAGE>
 
shall be authenticated in lieu of or in exchange for any Securities canceled as
provided in this Section, except as expressly permitted by this Indenture. All
canceled Securities shall be destroyed by the Trustee and the Trustee shall
deliver to the Company a certificate of such destruction.

   Section 3.10.   Computation of Interest.

   Except as otherwise specified as contemplated by Section 3.1 for Securities
of any series, interest on the Securities of each series for any period shall be
computed on the basis of a 360-day year of twelve 30-day months and interest on
the Securities of each series for any partial period shall be computed on the
basis of the number of days elapsed in a 360-day year of twelve 30-day months.



   Section 3.11.   Deferrals of Interest Payment Dates.

   If specified as contemplated by Section 2.1 or Section 3.1 with respect to
the Securities of a particular series, so long as no Event of Default has
occurred and is continuing, the Company shall have the right, at any time during
the term of such series, from time to time to defer the payment of interest on
such Securities for such period or periods as may be specified as contemplated
by Section 3.1 (each, an "Extension Period") during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date. No Extension Period shall end on a date other than an
Interest Payment Date. At the end of any such Extension Period the Company shall
pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law); provided, however, that
no Extension Period shall extend beyond the Stated Maturity of the principal of
the Securities of such series; provided, further, that during any such Extension
Period, the Company shall not, and shall not permit any Subsidiary to, (i)
declare or pay any dividends or distributions on, or redeem, purchase, acquire
or make a liquidation payment with respect to, any of the Company's capital
stock, or (ii) make any payment of principal of or interest or premium, if any,
on or repay, repurchase or redeem any debt security of the Company that ranks
pari passu with or junior in interest to the Securities of such series or make
any guarantee payments with respect to any guarantee by the Company of the debt
securities of any Subsidiary of the Company that by their terms rank pari passu
with or junior in interest to the securities of such series (other than (a)
dividends or distributions in Common Stock, (b) any declaration of a dividend in
connection with the implementation of a Rights Plan, the issuance of any Common
Stock of any class or series of preferred stock of the Company under any Rights
Plan or the repurchase of any rights distributed pursuant to a Rights Plan, (c)
payments under any Mellon Guarantee, and (d) purchases of Common Stock related
to the issuance of Common Stock under any of the Company's benefit plans for its
directors, officers or employees, related to the issuance of common stock or
rights under a dividend reinvestment and stock purchase plan, or related to the
issuance of common stock (or securities convertible into or exchangeable for
common stock) as consideration in an acquisition transaction). Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that no Extension Period shall exceed the
period or periods specified in such Securities or extend beyond the Stated
Maturity of the principal of such Securities. Upon termination of any Extension
Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due on any Interest Payment Date, the Company may elect
to begin a new Extension Period, subject to the above requirements. No interest
shall be due 

                                       32
<PAGE>
 
and payable during an Extension Period, except at the end thereof. The Company
shall give the Holders of the Securities of such series and the Trustee notice
of its election to begin any such Extension Period at least one Business Day
prior to the next succeeding Interest Payment Date on which interest on
Securities of such series would be payable but for such deferral or, with
respect to the Securities of a series issued to a Mellon Trust, so long as such
Securities are held by such Mellon Trust, prior to the earlier of (i) the next
succeeding date on which Distributions on the Preferred Securities of such
Mellon Trust would be payable but for such deferral or (ii) the date the
Administrative Trustees of such Mellon Trust are required to give notice to any
securities exchange or other applicable self-regulatory organization or to
holders of such Preferred Securities of the record date or the date such
Distributions are payable, but in any event not less than one Business Day
prior to such record date.

   The Trustee shall promptly give notice of the Company's election to begin any
such Extension Period to the Holders of the Outstanding Securities of such
series.

   Section 3.12.   Right of Set-Off.

   With respect to the Securities of a series issued to a Mellon Trust,
notwithstanding anything to the contrary in the Indenture, the Company shall
have the right to set-off any payment it is otherwise required to make
thereunder in respect of any such Security to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under the Mellon Guarantee relating to such Security or under Section
5.8 of the Indenture.

   Section 3.13.   Agreed Tax Treatment.

   Each Security issued hereunder shall provide that the Company and, by its
acceptance of a Security or a beneficial interest therein, the Holder of, and
any Person that acquires a beneficial interest in, such Security agree that for
United States Federal, state and local tax purposes it is intended that such
Security constitute indebtedness.

   Section 3.14.   Shortening or Extension of Stated Maturity.

   If specified as contemplated by Section 2.1 or Section 3.1 with respect to
the Securities of a particular series, the Company shall have the right to (i)
shorten the Stated Maturity of the principal of the Securities of such series at
any time to any date not earlier than the first date on which the Company has
the right to redeem the Securities of such series, and (ii) extend the Stated
Maturity of the principal of the Securities of such series at any time at its
election for one or more periods, but in no event to a date later than the 49th
anniversary of the first Interest Payment Date following the Original Issue Date
of the Securities of such series; provided that, if the Company elects to
exercise its right to extend the Stated Maturity of the principal of the
Securities of such series pursuant to clause (ii), above, at the time such
election is made and at the time of extension (A) the Company is not in
bankruptcy, otherwise insolvent or in liquidation, (B) the Company is not in
default in the payment of any interest or principal on such Securities, (C) in
the case of any series of Securities issued to a Mellon Trust, such Mellon Trust
is not in arrears on payments of Distributions on the Preferred Securities
issued by such Mellon Trust and no deferred Distributions are accumulated and

                                       33
<PAGE>
 
(D) such Securities are rated not less than BBB- by S&P or Baa3 by Moody's or
the equivalent by any other nationally recognized statistical rating
organization. In the event the Company elects to shorten or extend the Stated
Maturity of the Series A Subordinated Debentures, it shall give notice to the
Trustee, and the Trustee shall give notice of such shortening or extension to
the Holders, no less than 30 and no more than 60 days prior to the effectiveness
thereof.



   Section 3.15.   CUSIP Numbers.

   The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

                           SATISFACTION AND DISCHARGE

   Section 4.1.   Satisfaction and Discharge of Indenture.

   This Indenture shall, upon Company Request, cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for and as otherwise provided in this
Section 4.1) and the Trustee, on demand of and at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture, when

  (1) either

  (A) all Securities theretofore authenticated and delivered (other than (i)
Securities which have been destroyed, lost or stolen and which have been
replaced or paid as provided in Section 3.6 and (ii) Securities for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter repaid to the Company or discharged from
such trust, as provided in Section 10.3) have been delivered to the Trustee for
cancellation; or

  (B) all such Securities not theretofore delivered to the Trustee for
cancellation

  (i)  have become due and payable, or

  (ii) will become due and payable at their Stated Maturity within one year of
       the date of deposit, or

                                       34
<PAGE>
 
  (iii)  are to be called for redemption within one year under arrangements
       satisfactory to the Trustee for the giving of notice of redemption by the
       Trustee in the name, and at the expense, of the Company,

   and the Company, in the case of Clause (B) (i), (ii) or (iii) above, has
   deposited or caused to be deposited with the Trustee as trust funds in trust
   for such purpose an amount in the currency or currencies in which the
   Securities of such series are payable sufficient to pay and discharge the
   entire indebtedness on such Securities not theretofore delivered to the
   Trustee for cancellation, for principal (and premium, if any) and interest
   (including any Additional Interest) to the date of such deposit (in the case
   of Securities which have become due and payable) or to the Stated Maturity
   or Redemption Date, as the case may be;

  (2) the Company has paid or caused to be paid all other sums payable hereunder
by the Company; and

  (3) the Company has delivered to the Trustee an Officers' Certificate and an
Opinion of Counsel each stating that all conditions precedent herein provided
for relating to the satisfaction and discharge of this Indenture have been
complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Trustee to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

   Section 4.2.   Application of Trust Money.

   Subject to the provisions of the last paragraph of Section 10.3, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust and
applied by the Trustee, in accordance with the provisions of the Securities and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for the payment of which such money or obligations have been
deposited with or received by the Trustee.


                                   ARTICLE V

                                    REMEDIES

   Section 5.1.   Events of Default.

   "Event of Default", wherever used herein with respect to the Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be 

                                       35
<PAGE>
 
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

  (1) default in the payment of any interest upon any Security of that series,
including any Additional Interest in respect thereof, when it becomes due and
payable, and continuance of such default for a period of 30 days (subject to the
deferral of any due date in the case of an Extension Period); or



  (2) default in the payment of the principal of (or premium, if any, on) any
Security of that series at its Maturity; or

  (3) default in the performance, or breach, in any material respect, of any
covenant or warranty of the Company in this Indenture (other than a covenant or
warranty a default in the performance of which or the breach of which is
elsewhere in this Section specifically dealt with), and continuance of such
default or breach for a period of 90 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default
or breach and requiring it to be remedied; or

  (4) the entry of a decree or order by a court having jurisdiction in the
premises adjudging the Company a bankrupt or insolvent, or approving as properly
filed a petition seeking reorganization, arrangement, adjustment or composition
of or in respect of the Company under any applicable Federal or State
bankruptcy, insolvency, reorganization or other similar law, or appointing a
receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property or ordering
the winding up or liquidation of its affairs, and the continuance of any such
decree or order unstayed and in effect for a period of 60 consecutive days; or

  (5) the institution by the Company of proceedings to be adjudicated a bankrupt
or insolvent, or the consent by it to the institution of bankruptcy or
insolvency proceedings against it, or the filing by it of a petition or answer
or consent seeking reorganization or relief under any applicable Federal or
State bankruptcy, insolvency, reorganization or other similar law, or the
consent by it to the filing of any such petition or to the appointment of a
receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property, or the
making by it of an assignment for the benefit for creditors, or the admission by
it in writing of its inability to pay its debts generally as they become due and
its willingness to be adjudicated a bankrupt, or the taking of corporate action
by the Company in furtherance of any such action; or

  (6) any other Event of Default provided with respect to Securities of that
series.

   Section 5.2.   Acceleration of Maturity; Rescission and Annulment.

   If an Event of Default (other than an Event of Default specified in Section
5.1(4) or 5.1(5)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding

                                       36
<PAGE>
 
Securities of that series may declare the principal amount (or, if the
Securities of that series are Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of all the 
Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), provided that,
in the case of the Securities of a series issued to a Mellon Trust, if, upon an
Event of Default, the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Securities of that series fail to declare the
principal of all the Securities of that series to be immediately due and
payable, the holders of at least 25% in aggregate liquidation amount of the
corresponding series of Preferred Securities then outstanding shall have such
right by a notice in writing to the Company and the Trustee; and upon any such
declaration such principal amount (or specified portion thereof) of and the
accrued interest (including any Additional Interest) on all the Securities of
such series shall become immediately due and payable. Payment of principal and
interest (including any Additional Interest) on such Securities shall remain
subordinated to the extent provided in Article XIII notwithstanding that such
amount shall become immediately due and payable as herein provided. If an Event
of Default specified in Section 5.1(4) or 5.1(5) with respect to Securities of
any series at the time Outstanding occurs, the principal amount of all the
Securities of that series (or, if the Securities of that series are Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms of that series) shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable.

   At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

  (1) the Company has paid or deposited with the Trustee a sum sufficient to
pay:

  (A) all overdue installments of interest (including any Additional Interest)
on all Securities of that series,

  (B) the principal of (and premium, if any, on) any Securities of that series
which have become due otherwise than by such declaration of acceleration and
interest thereon at the rate borne by the Securities, and

  (C) all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel; and

  (2) all Events of Default with respect to Securities of that series, other
than the non-payment of the principal of Securities of that series which has
become due solely by such acceleration, have been cured or waived as provided in
Section 5.13.

   In the case of Securities of a series issued to a Mellon Trust, the holders
of a majority in aggregate Liquidation Amount (as defined in the Trust Agreement
under which such Mellon Trust is formed) of the related series of Preferred
Securities issued by such Mellon Trust shall also have 

                                       37
<PAGE>
 
the right to rescind and annul such declaration and its consequences by written
notice to the Company and the Trustee, subject to the satisfaction of the
conditions set forth in Clauses (1) and (2) above of this Section 5.2.

   No such rescission shall affect any subsequent default or impair any right
consequent thereon.



   Section 5.3.   Collection of Indebtedness and Suits for Enforcement by
Trustee.

   The Company covenants that if:

  (1) default is made in the payment of any installment of interest (including
any Additional Interest) on any Security when such interest becomes due and
payable and such default continues for a period of 30 days, or

  (2) default is made in the payment of the principal of (and premium, if any,
on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal, including any sinking fund payment or
analogous obligations (and premium, if any) and interest (including any
Additional Interest); and, in addition thereto, all amounts owing the Trustee
under Section 6.7.

   If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

   If an Event of Default with respect to Securities of any series occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.

   Section 5.4.   Trustee May File Proofs of Claim.

   In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors,

  (a) the Trustee (irrespective of whether the principal of the Securities of
any series shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the 

                                       38
<PAGE>
 
Trustee shall have made any demand on the Company for the payment of overdue
principal (and premium, if any) or interest (including any Additional
Interest)) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

  (i) to file and prove a claim for the whole amount of principal (and premium,
if any) and interest (including any Additional Interest) owing and unpaid in
respect to the Securities and to file such other papers or documents as may be
necessary or advisable and to take any and all actions as are authorized under
the Trust Indenture Act in order to have the claims of the Holders and any
predecessor to the Trustee under Section 6.7 allowed in any such judicial
proceedings; and

  (ii) in particular, the Trustee shall be authorized to collect and receive any
moneys or other property payable or deliverable on any such claims and to
distribute the same in accordance with Section 5.6; and

  (b) any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee for distribution in accordance
with Section 5.6, and in the event that the Trustee shall consent to the making
of such payments directly to the Holders, to pay to the Trustee any amount due
to it and any predecessor Trustee under Section 6.7.

   Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

   Section 5.5.   Trustee May Enforce Claim Without Possession of Securities.

   All rights of action and claims under this Indenture or the Securities may be
prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of all the amounts owing the Trustee and any predecessor Trustee
under Section 6.7, its agents and counsel, be for the ratable benefit of the
Holders of the Securities in respect of which such judgment has been recovered.

   Section 5.6.   Application of Money Collected.

   Any money or property collected or to be applied by the Trustee with respect
to a series of Securities pursuant to this Article shall be applied in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money or property on account of principal (or premium, if
any) or interest (including any Additional Interest), upon presentation of the
Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

                                       39
<PAGE>
 
  FIRST: To the payment of all amounts due the Trustee and any predecessor
Trustee under Section 6.7;

  SECOND: Subject to Article XIII, to the payment of the amounts then due and
unpaid upon such series of Securities for principal (and premium, if any) and
interest (including any Additional Interest), in respect of which or for the
benefit of which such money has been collected, ratably, without preference or
priority of any kind, according to the amounts due and payable on such series of
Securities for principal (and premium, if any) and interest (including any
Additional Interest), respectively; and

  THIRD: The balance, if any, to the Person or Persons entitled thereto.

   Section 5.7.   Limitation on Suits.

   No Holder of any Securities of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture or for the
appointment of a receiver, assignee, trustee, liquidator, sequestrator (or other
similar official) or for any other remedy hereunder, unless:

  (1) such Holder has previously given written notice to the Trustee of a
continuing Event of Default with respect to the Securities of that series;

  (2) the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

  (3) such Holder or Holders have offered to the Trustee reasonable indemnity
against the costs, expenses and liabilities to be incurred in compliance with
such request;

  (4) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity has failed to institute any such proceeding; and

  (5) no direction inconsistent with such written request has been given to the
Trustee during such 60-day period by the Holders of a majority in principal
amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing itself of, any
provision of this Indenture to affect, disturb or prejudice the rights of any
other Holders of Securities, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

                                       40

   Section 5.8.   Unconditional Right of Holders to Receive Principal, Premium
and Interest; Direct Action by Holders of Preferred Securities.

   Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right which is absolute and unconditional to receive
payment of the principal of (and premium, if any) and (subject to Section 3.7)
interest (including any Additional Interest) on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such
payment, and such right shall not be impaired without the consent of such
Holder. In the case of Securities of a series issued to a Mellon Trust, any
holder of the corresponding series of Preferred Securities issued by such
Mellon Trust shall have the right, upon the occurrence of an Event of Default
described in Section 5.1(1) or 5.1(2), to institute a suit directly against the
Company for enforcement of payment to such holder of principal of (premium, if
any) and (subject to Section 3.7) interest (including any Additional Interest)
on the Securities having a principal amount equal to the aggregate Liquidation
Amount (as defined in the Trust Agreement under which such Mellon Trust is
formed) of such Preferred Securities of the corresponding series held by such
holder.

   Section 5.9.   Restoration of Rights and Remedies.

   If the Trustee, any Holder or any holder of Preferred Securities has
instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee, such Holder or such holder of
Preferred Securities, then and in every such case the Company, the Trustee, the
Holders and such holder of Preferred Securities shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee, the Holders and the holders of Preferred Securities shall continue as
though no such proceeding had been instituted.

   Section 5.10.   Rights and Remedies Cumulative.

   Except as otherwise provided in the last paragraph of Section 3.6, no right
or remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

   Section 5.11.   Delay or Omission Not Waiver.

   No delay or omission of the Trustee, any Holder of any Security or any holder
of any Preferred Security to exercise any right or remedy accruing upon any
Event of Default shall impair any such right or remedy or constitute a waiver of
any such Event of Default or an acquiescence therein.

   Every right and remedy given by this Article or by law to the Trustee or to
the Holders and the right and remedy given to the holders of Preferred
Securities by Section 5.8 may be exercised from

                                       41
<PAGE>
 
time to time, and as often as may be deemed expedient, by the Trustee, the
Holders or the holders of Preferred Securities, as the case may be.



   Section 5.12.   Control by Holders.

   The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that:

  (1) such direction shall not be in conflict with any rule of law or with this
Indenture,

  (2) the Trustee may take any other action deemed proper by the Trustee which
is not inconsistent with such direction, and

  (3) subject to the provisions of Section 6.1, the Trustee shall have the right
to decline to follow such direction if a Responsible Officer or Officers of the
Trustee shall, in good faith, determine that the proceeding so directed would be
unjustly prejudicial to the Holders not joining in any such direction or would
involve the Trustee in personal liability.

   Section 5.13.   Waiver of Past Defaults.

   The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series and, in the case of any Securities of a
series issued to a Mellon Trust, the holders of Preferred Securities issued by
such Mellon Trust may waive any past default hereunder and its consequences with
respect to such series except a default:

  (1) in the payment of the principal of (or premium, if any) or interest
(including any Additional Interest) on any Security of such series, or

  (2) in respect of a covenant or provision hereof which under Article IX cannot
be modified or amended without the consent of the Holder of each Outstanding
Security of such series affected.

  Any such waiver shall be deemed to be on behalf of the Holders of all the
Securities of such series or, in the case of a waiver by holders of Preferred
Securities issued by such Mellon Trust, by all holders of Preferred Securities
issued by such Mellon Trust.

   Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

   Section 5.14.   Undertaking for Costs.

   All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the

                                       42
<PAGE>
 
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit,
and that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest (including any Additional Interest) on any Security on or after the
respective Stated Maturities expressed in such Security.

   Section 5.15.   Waiver of Usury, Stay or Extension Laws.

   The Company covenants (to the extent that it may lawfully do so) that it will
not at any time insist upon, or plead, or in any manner whatsoever claim or take
the benefit or advantage of, any usury, stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.


                                   ARTICLE VI

                                  THE TRUSTEE

   Section 6.1.   Certain Duties and Responsibilities.

  (a) Except during the continuance of an Event of Default,

  (1) the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

  (2) in the absence of bad faith on its part, the Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture; but in the case of any such
certificates or opinions which by any provisions hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Indenture.

  (b) In case an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of his own affairs.

                                       43
<PAGE>
 
  (c) No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act,
or its own willful misconduct except that

  (1) this Subsection shall not be construed to limit the effect of Subsection
(a) of this Section;

  (2) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer, unless it shall be proved that the Trustee was
negligent in ascertaining the pertinent facts; and

  (3) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of
Holders pursuant to Section 5.12 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture with respect
to the Securities of such series.

  (d) No provision of this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur any financial liability in the performance of
any of its duties hereunder, or in the exercise of any of its rights or powers,
if there shall be reasonable grounds for believing that repayment of such funds
or adequate indemnity against such risk or liability is not reasonably assured
to it.

  (e) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

   Section 6.2.   Notice of Defaults.

   Within 90 days after actual knowledge by a Responsible Officer of the Trustee
of the occurrence of any default hereunder with respect to the Securities of any
series, the Trustee shall transmit by mail to all Holders of Securities of such
series, as their names and addresses appear in the Securities Register, notice
of such default, unless such default shall have been cured or waived; provided,
however, that, except in the case of a default in the payment of the principal
of (or premium, if any) or interest (including any Additional Interest) on any
Security of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determines that the withholding of such notice is in the interests of the
Holders of Securities of such series; and provided, further, that, in the case
of any default of the character specified in Section 5.1(3), no such notice to
Holders of Securities of such series shall be given until at least 30 days after
the occurrence thereof. For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to Securities of such series.

                                       44

   Section 6.3.   Certain Rights of Trustee.

   Subject to the provisions of Section 6.1:

  (a) the Trustee may rely and shall be protected in acting or refraining from

paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

  (c) whenever in the administration of this Indenture the Trustee shall deem it

omitting any action hereunder, the Trustee (unless other evidence be herein
specifically prescribed) may, in the absence of bad faith on its part, rely upon
an Officers' Certificate;

  (d) the Trustee may consult with counsel and the advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection in

and in reliance thereon;

  (e) the Trustee shall be under no obligation to exercise any of the rights or
powers vested in it by this Indenture at the request or direction of any of the
Holders pursuant to this Indenture, unless such Holders shall have offered to
the Trustee reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction;

  (f) the Trustee shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, indenture, Security or
other paper or document, but the Trustee in its discretion may make such inquiry
or investigation into such facts or matters as it may see fit, and, if the
Trustee shall determine to make such inquiry or investigation, it shall be
entitled to examine the books, records and premises of the Company, personally
or by agent or attorney; and

  (g) the Trustee may execute any of the trusts or powers hereunder or perform
any duties hereunder either directly or by or through agents or attorneys and
the Trustee shall not be responsible for any misconduct or negligence on the
part of any agent or attorney appointed with due care by it hereunder.

   Section 6.4.   Not Responsible for Recitals or Issuance of Securities.

   The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities. Neither the 

                                       45
<PAGE>
 
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of the Securities or the proceeds thereof.

   Section 6.5.   May Hold Securities.

   The Trustee, any Authenticating Agent, any Paying Agent, any Securities
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
6.8 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Securities
Registrar or such other agent.

   Section 6.6.   Money Held in Trust.

   Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

   Section 6.7.   Compensation and Reimbursement.

   The Company agrees

  (1) to pay to the Trustee from time to time reasonable compensation for all
services rendered by it hereunder in such amounts as the Company and the Trustee
shall agree from time to time (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust);

  (2) to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel), except any such expense,
disbursement or advance as may be attributable to its negligence or bad faith;
and

  (3) to indemnify the Trustee for, and to hold it harmless against, any loss,
liability or expense (including the reasonable compensation and the expenses and
disbursements of its agents and counsel) incurred without negligence or bad
faith, arising out of or in connection with the acceptance or administration of
this trust or the performance of its duties hereunder, including the costs and
expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder. This
indemnification shall survive the termination of this Agreement.

   To secure the Company's payment obligations in this Section, the Company and
the Holders agree that the Trustee shall have a lien prior to the Securities on
all money or property held or collected by the Trustee. Such lien shall survive
the satisfaction and discharge of this Indenture.

                                       46
<PAGE>
 
   When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under the Bankruptcy Reform Act of 1978 or any successor statute.

   Section 6.8.   Disqualification; Conflicting Interests.

   The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act. Nothing
herein shall prevent the Trustee from filing with the Commission the application
referred to in the second to last paragraph of said Section 310(b).

   Section 6.9.   Corporate Trustee Required; Eligibility.

   There shall at all times be a Trustee hereunder which shall be

  (a) a corporation organized and doing business under the laws of the United
States of America or of any State or Territory or the District of Columbia,
authorized under such laws to exercise corporate trust powers and subject to
supervision or examination by Federal, State, Territorial or District of
Columbia authority, or

  (b) a corporation or other Person organized and doing business under the laws
of a foreign government that is permitted to act as Trustee pursuant to a rule,
regulation or order of the Commission, authorized under such laws to exercise
corporate trust powers, and subject to supervision or examination by authority
of such foreign government or a political subdivision thereof substantially
equivalent to supervision or examination applicable to United States
institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by Federal or State authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then,
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve
as Trustee for the Securities of any series issued hereunder.

   Section 6.10.   Resignation and Removal; Appointment of Successor.

   (a)   No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

                                       47
<PAGE>
 
   (b)   The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

   (c)   The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

   (d)   If at any time:

  (1) the Trustee shall fail to comply with Section 6.8 after written request
therefor by the Company or by any Holder who has been a bona fide Holder of a
Security for at least six months, or

  (2) the Trustee shall cease to be eligible under Section 6.9 and shall fail to
resign after written request therefor by the Company or by any such Holder, or

  (3) the Trustee shall become incapable of acting or shall be adjudged a
bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in any such case, (i) the Company, acting pursuant to the authority of a
Board Resolution, may remove the Trustee with respect to all Securities, or (ii)
subject to Section 5.14, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.

   (e) If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause with respect to
the Securities of one or more series, the Company, by a Board Resolution, shall
promptly appoint a successor Trustee with respect to the Securities of that or
those series. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee with respect to the Securities of such series and supersede
the successor Trustee appointed by the Company. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Security for at least

   (f) The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series by mailing

Holders of Securities of such series as their names and addresses appear in the
Securities Register. Each notice shall include the name of the successor Trustee

   Section 6.11.   Acceptance of Appointment by Successor.

   (a) In case of the appointment hereunder of a successor Trustee with respect
to all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.

   (b) In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts, and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

   (c) Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all rights, powers and trusts referred to in paragraph
(a) or (b) of this Section, as the case may be.

   (d) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.

   Section 6.12.   Merger, Conversion, Consolidation or Succession to Business.

   Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated, and in case any
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor Trustee or in
the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the
Securities or in this Indenture that the certificate of the Trustee shall have.

   Section 6.13.   Preferential Collection of Claims Against Company.

   If and when the Trustee shall be or become a creditor of the Company (or any
other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

   Section 6.14.   Appointment of Authenticating Agent.

   The Trustee may appoint an Authenticating Agent or Agents with respect to one
or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon original issue and
upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 3.6, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, or of any State or Territory or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining 

                                       50
<PAGE>
 
authority, then for the purposes of this Section the combined capital and
surplus of such Authenticating Agent shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published.
If at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

   Any corporation into which an Authenticating Agent may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Authenticating Agent shall be
a party, or any corporation succeeding to all or substantially all of the
corporate trust business of an Authenticating Agent shall be the successor
Authenticating Agent hereunder, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

   An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provision of this Section.

   The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 6.7.

   If an appointment with respect to one or more series is made pursuant to this
Section, the Securities of such series may have endorsed thereon, in addition to
the Trustee's certificate of authentication, an alternative certificate of
authentication in the following form:

   This is one of the Securities referred to in the within mentioned Indenture.

convey, transfer or lease its properties and assets substantially as an entirety
to any Person, and no Person shall consolidate with or merge into the Company or
convey, transfer or lease its properties and assets substantially as an entirety

Company is merged or the Person which acquires by conveyance or transfer, or
which leases, the properties and assets of the Company substantially as

Event of Default, shall have happened and be continuing;

  (3) in the case of the Securities of a series issued to a Mellon Trust, such

may rely upon such Officers' Certificate and Opinion of Counsel as conclusive
evidence that such transaction complies with this Section 8.1.

   Section 8.2.   Successor Corporation Substituted.

   Upon any consolidation or merger by the Company with or into any other
Person, or any conveyance, transfer or lease by the Company of its properties
and assets substantially as an entirety to any Person in accordance with Section

Company is merged or to which such conveyance, transfer or lease is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under this Indenture with the same effect as if such successor
Person had been named as the Company herein; and in the event of any such
conveyance, transfer or lease the Company shall be discharged from all
obligations and covenants under the Indenture and the Securities and may be
dissolved and liquidated.

   Such successor Person may cause to be signed, and may issue either in its own
name or in the name of the Company, any or all of the Securities issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee; and, upon the order of such successor Person instead
of the Company and subject to all the terms, conditions and limitations in this

Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication pursuant to such provisions and
any Securities which such successor Person thereafter shall cause to be signed

legal rank and benefit

                                       54
<PAGE>

accordance with the terms of this Indenture as though all of such Securities
had been issued at the date of the execution hereof.

   In case of any such consolidation, merger, sale, conveyance or lease, such
changes in phraseology and form may be made in the Securities thereafter to be
issued as may be appropriate.

                                   COVENANTS

   Section 10.1.   Payment of Principal, Premium and Interest.

   The Company covenants and agrees for the benefit of each series of securities
that it will duly and punctually pay the principal of (and premium, if any) and
interest on the Securities of that series in accordance with the terms of such
Securities and this Indenture.

   Section 10.2.   Maintenance of Office or Agency.

   The Company will maintain in each Place of Payment for any series of
Securities, an office or agency where Securities of that series may be presented
or surrendered for payment and an office or agency where Securities of that
series may be surrendered for transfer or exchange and where notices and demands
to or upon the Company in respect of the Securities of that series and this
Indenture may be served. The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Company shall fail to maintain
such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

   The Company may also from time to time designate one or more other offices or
agencies where the Securities may be presented or surrendered for any or all of
such purposes, and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in each Place of
Payment for Securities of any series for such purposes. The Company will give
prompt written

                                       58
<PAGE>
 
notice to the Trustee of any such designation and any change in the location of
any such office or agency.

   Section 10.3.   Money for Security Payments to be Held in Trust.

   If the Company shall at any time act as its own Paying Agent with respect to
any series of Securities, it will, on or before each due date of the principal
of (and premium, if any) or interest on any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided, and will promptly notify the Trustee of its failure so to
act.

   Whenever the Company shall have one or more Paying Agents, it will, prior to
10:00 a.m. New York City time on each due date of the principal of or interest
on any Securities, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal and premium
(if any) or interest, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its failure so to act.

   The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will:

  (1) hold all sums held by it for the payment of the principal of (and premium,
if any) or interest on Securities in trust for the benefit of the Persons
entitled thereto until such sums shall be paid to such Persons or otherwise
disposed of as herein provided;

  (2) give the Trustee notice of any default by the Company (or any other
obligor upon the Securities) in the making of any payment of principal (and
premium, if any) or interest;

  (3) at any time during the continuance of any such default, upon the written
request of the Trustee, forthwith pay to the Trustee all sums so held in trust
by such Paying Agent; and

  (4) comply with the provisions of the Trust Indenture Act applicable to it as
a Paying Agent.

   The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

   Any money deposited with the Trustee or any Paying Agent, or then held by the
Company, in trust for the payment of the principal of (and premium, if any) or
interest on any Security and remaining unclaimed for two years after such
principal (and premium, if any) or interest has become 

                                       59
<PAGE>
 
due and payable shall (unless otherwise required by mandatory provision of
applicable escheat or abandoned or unclaimed property law) be paid on Company
Request to the Company, or (if then held by the Company) shall (unless
otherwise required by mandatory provision of applicable escheat or abandoned or
unclaimed property law) be discharged from such trust; and the Holder of such
Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

   Section 10.4.   Statement as to Compliance.

   The Company shall deliver to the Trustee, within 120 days after the end of
each calendar year of the Company ending after the date hereof, an Officers'
Certificate covering the preceding calendar year, stating whether or not to the
best knowledge of the signers thereof the Company is in default in the
performance, observance or fulfillment of or compliance with any of the terms,
provisions, covenants and conditions of this Indenture, and if the Company shall
be in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge. For the purpose of this Section 10.4, compliance
shall be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

   Section 10.5.   Waiver of Certain Covenants.

   The Company may omit in any particular instance to comply with any covenant
or condition provided pursuant to Section 3.1, 9.1(3) or 9.1(4) with respect to
the Securities of any series, if before or after the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company in respect of any such covenant
or condition shall remain in full force and effect.

   Section 10.6.   Additional Sums.

   In the case of the Securities of a series issued to a Mellon Trust, so long
as no Event of Default has occurred and is continuing and except as otherwise
specified as contemplated by Section 2.1 or Section 3.1, in the event that (i) a
Mellon Trust is the Holder of all of the Outstanding Securities of such series,
(ii) a Tax Event or a Capital Treatment Event in respect of such Mellon Trust
shall have occurred and be continuing and (iii) the Company shall not have (A)
redeemed the Securities of such series pursuant to Section 11.7(b) or (B)
terminated such Mellon Trust pursuant to Section 9.2(b) of the related Trust
Agreement, the Company shall pay to such Mellon Trust (and its permitted

                                       60
<PAGE>
 
successors or assigns under the related Trust Agreement) for so long as such
Mellon Trust (or its permitted successor or assignee) is the registered holder
of any Securities of such series, such additional amounts as may be necessary in
order that the amount of Distributions (including any Additional Amounts (as
defined in such Trust Agreement)) then due and payable by such Mellon Trust on
the related Preferred Securities and Common Securities that at any time remain
outstanding in accordance with the terms thereof shall not be reduced as a
result of any Additional Taxes (the "Additional Sums"). Whenever in this
Indenture or the Securities there is a reference in any context to the payment
of principal of or interest on the Securities, such mention shall be deemed to
include mention of the payments of the Additional Sums provided for in this
paragraph to the extent that, in such context, Additional Sums are, were or
would be payable in respect thereof pursuant to the provisions of this paragraph
and express mention of the payment of Additional Sums (if applicable) in any
provisions hereof shall not be construed as excluding Additional Sums in those
provisions hereof where such express mention is not made; provided, however,
that the deferral of the payment of interest pursuant to Section 3.11 or the
Securities shall not defer the payment of any Additional Sums that may be due
and payable.

   Section 10.7.   Additional Covenants.

   The Company covenants and agrees with each Holder of Securities of each
series that it shall not, and it shall not permit any Subsidiary of the Company
to, (a) declare or pay any dividends or distributions on, or redeem purchase,
acquire or make a liquidation payment with respect to, any shares of the
Company's capital stock, or (b) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu with or junior in interest to the Securities of
such series or make any guarantee payments with respect to any guarantee by the
Company of debt securities of any subsidiary of the Company if such guarantee
ranks pari passu with or junior in interest to the Securities (other than (a)
dividends or distributions in Common Stock, (b) any declaration of a dividend in
connection with the implementation of a Rights Plan, the issuance of any rights,
of any Common Stock or any class or series of preferred stock of the Company or
of any other property under any Rights Plan or the repurchase of any rights
distributed pursuant to a Rights Plan, (c) payments under any Mellon Guarantee,
and (d) purchases of Common Stock related to the issuance of Common Stock under
any of the Company's benefit plans for its directors, officers or employees,
related to the issuance of common stock or rights under a dividend reinvestment
and stock purchase plan, or related to the issuance of common stock (or
securities convertible into or exchangeable for common stock) as consideration
in an acquisition transaction) if at such time (i) there shall have occurred any
event of which the Company has actual knowledge that (A) with the giving of
notice or the lapse of time or both, would constitute an Event of Default with
respect to the Securities of such series and (B) in respect of which the Company
shall not have taken reasonable steps to cure, (ii) if the Securities of such
series are held by a Mellon Trust, the Company shall be in default with respect
to its payment of any obligations under the Mellon Guarantee relating to the
Preferred Securities issued by such Mellon Trust or (iii) the Company shall have
given notice of its election to begin an Extension Period with respect to the
Securities of such series as provided herein and shall not have rescinded such
notice, or such Extension Period, or any extension thereof, shall be
continuing.

                                       61
<PAGE>
 
   The Company also covenants with each Holder of Securities of a series issued
to a Mellon Trust (i) to maintain directly or indirectly 100% ownership of the
Common Securities of such Mellon Trust; provided, however, that any permitted
successor of the Company hereunder may succeed to the Company's ownership of
such Common Securities, (ii) not to voluntarily terminate, wind-up or liquidate
such Mellon Trust, except (a) in connection with a distribution of the
Securities of such series to the holders of Preferred Securities in liquidation
of such Mellon Trust or (b) in connection with certain mergers, consolidations
or amalgamations permitted by the related Trust Agreement and (iii) to use its
reasonable efforts, consistent with the terms and provisions of such Trust
Agreement, to cause such Mellon Trust to remain classified as a grantor trust
and not an association taxable as a corporation for United States federal income
tax purposes.


                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

   Section 11.1.   Applicability of This Article.

   Redemption of Securities of any series (whether by operation of a sinking
fund or otherwise) as permitted or required by any form of Security issued
pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; provided, however, that if any provision of any such
form of Security shall conflict with any provision of this Article, the
provision of such form of Security shall govern. Except as otherwise set forth
in the form of Security for such series, each Security of such series shall be
subject to partial redemption only in the amount of $25 or, in the case of the
Securities of a series issued to a Mellon Trust, $25, or integral multiples
thereof.

   Section 11.2.   Election to Redeem; Notice to Trustee.

   The election of the Company to redeem any Securities shall be evidenced by or
pursuant to a Board Resolution. In case of any redemption at the election of the
Company of less than all of the Securities of any particular series and having
the same terms, the Company shall, not less than 30 nor more than 60 days prior
to the Redemption Date (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such date and of the principal amount of
Securities of that series to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities, the Company shall furnish the Trustee
with an Officers' Certificate and an Opinion of Counsel evidencing compliance
with such restriction.

   Section 11.3.   Selection of Securities to be Redeemed.

   If less than all the Securities of any series are to be redeemed (unless all
the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such

                                       62
<PAGE>
 
series, provided that the unredeemed portion of the principal amount of any
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security. If less than all the
Securities of such series and of a specified tenor are to be redeemed (unless
such redemption affects only a single Security), the particular Securities to
be redeemed shall be selected not more than 60 days prior to the Redemption
Date by the Trustee, from the Outstanding Securities of such series and
specified tenor not previously called for redemption in accordance with the
preceding sentence.

   The Trustee shall promptly notify the Company in writing of the Securities
selected for partial redemption and the principal amount thereof to be redeemed.
For all purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Securities shall relate, in the case of
any Security redeemed or to be redeemed only in part, to the portion of the
principal amount of such Security which has been or is to be redeemed. If the
Company shall so direct, Securities registered in the name of the Company, any
Affiliate or any Subsidiary thereof shall not be included in the Securities
selected for redemption.

   Section 11.4.   Notice of Redemption.

   Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not later than the thirtieth day, and not earlier than the sixtieth day,
prior to the Redemption Date, to each Holder of Securities to be redeemed, at
the address of such Holder as it appears in the Securities Register.

   With respect to Securities of each series to be redeemed, each notice of
redemption shall state:

  (a) the Redemption Date;

  (b) the Redemption Price;

  (c) if less than all Outstanding Securities of such particular series and
having the same terms are to be redeemed, the identification (and, in the case
of partial redemption, the respective principal amounts) of the particular
Securities to be redeemed;

  (d) that on the Redemption Date, the Redemption Price will become due and
payable upon each such Security or portion thereof, and that interest thereon,
if any, shall cease to accrue on and after said date;

  (e) the place or places where such Securities are to be surrendered for
payment of the Redemption Price; and

  (f) that the redemption is for a sinking fund, if such is the case.

   Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall not be
irrevocable. The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice. In 

                                       63
<PAGE>
 
any case, a failure to give such notice by mail or any defect in the notice to
the Holder of any Security designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any
other Security.

   Section 11.5.   Deposit of Redemption Price.

   Prior to 10:00 a.m. New York City time on the Redemption Date specified in
the notice of redemption given as provided in Section 11.4, the Company will
deposit with the Trustee or with one or more Paying Agents (or if the Company is
acting as its own Paying Agent, the Company will segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and any accrued interest (including Additional Interest) on, all the
Securities which are to be redeemed on that date.

   Section 11.6.   Payment of Securities Called for Redemption.

   If any notice of redemption has been given as provided in Section 11.4, the
Securities or portion of Securities with respect to which such notice has been
given shall become due and payable on the date and at the place or places stated
in such notice at the applicable Redemption Price. On presentation and surrender
of such Securities at a Place of Payment in said notice specified, the said
securities or the specified portions thereof shall be paid and redeemed by the
Company at the applicable Redemption Price, together with accrued interest
(including any Additional Interest) to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 3.1, installments of
interest whose Stated Maturity is on or prior to the Redemption Date will be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.7.

   Upon presentation of any Security redeemed in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder thereof, at
the expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unredeemed
portion of the Security so presented and having the same Original Issue Date,
Stated Maturity and terms. If a Global Security is so surrendered, such new
Security will also be a new Global Security.

   If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal of and premium, if any, on such Security
shall, until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.

   Section 11.7.   Right of Redemption of Securities Initially Issued to a
Mellon Trust.

   In the case of the Securities of a series initially issued to a Mellon Trust,
except as otherwise specified as contemplated by Section 3.1, the Company, at
its option, may redeem such Securities (i) on or after the date five years after
the Original Issue Date of such Securities, in whole at any time or in part from
time to time, or (ii) upon the occurrence and during the continuation of a Tax
Event or a Capital Treatment Event, at any time within 90 days following the
occurrence of such Tax Event or 

                                       64
<PAGE>
 
Capital Treatment Event in respect of such Mellon Trust, in whole (but not in
part), in each case at a Redemption Price equal to 100% of the principal amount
thereof.


                                  ARTICLE XII

                                 SINKING FUNDS

   Section 12.1.   Applicability of Article.

   The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

   The minimum amount of any sinking fund payment provided for by the terms of
any Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any sinking fund payment in excess of such minimum amount which is
permitted to be made by the terms of such Securities of any series is herein
referred to as an "optional sinking fund payment". If provided for by the terms
of any Securities of any series, the cash amount of any sinking fund payment may
be subject to reduction as provided in Section 12.2. Each sinking fund payment
shall be applied to the redemption of Securities of any series as provided for
by the terms of such Securities.

   Section 12.2.   Satisfaction of Sinking Fund Payments with Securities.

   In lieu of making all or any part of a mandatory sinking fund payment with
respect to any Securities of a series in cash, the Company may at its option, at
any time no more than 16 months and no less than 30 days prior to the date on
which such sinking fund payment is due, deliver to the Trustee Securities of
such series (together with the unmatured coupons, if any, appertaining thereto)
theretofore purchased or otherwise acquired by the Company, except Securities of
such series that have been redeemed through the application of mandatory or
optional sinking fund payments pursuant to the terms of the Securities of such
series, accompanied by a Company Order instructing the Trustee to credit such
obligations and stating that the Securities of such series were originally
issued by the Company by way of bona fide sale or other negotiation for value;
provided that the Securities to be so credited have not been previously so
credited. The Securities to be so credited shall be received and credited for
such purpose by the Trustee at the redemption price for such Securities, as
specified in the Securities so to be redeemed, for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

   Section 12.3.   Redemption of Securities for Sinking Fund.

   Not less than 60 days prior to each sinking fund payment date for any series
of Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash in the currency in which
the Securities of such series are payable (except as provided pursuant to
Section 3.1) and the portion 

                                       65
<PAGE>
 
thereof, if any, which is to be satisfied by delivering and crediting
Securities pursuant to Section 12.2 and will also deliver to the Trustee any
Securities to be so delivered. Such Officers' Certificate shall be irrevocable
and upon its delivery the Company shall be obligated to make the cash payment
or payments therein referred to, if any, on or before the succeeding sinking
fund payment date. In the case of the failure of the Company to deliver such
Officers' Certificate (or, as required by this Indenture, the Securities and
coupons, if any, specified in such Officers' Certificate), the sinking fund
payment due on the succeeding sinking fund payment date for such series shall
be paid entirely in cash and shall be sufficient to redeem the principal amount
of the Securities of such series subject to a mandatory sinking fund payment
without the right to deliver or credit securities as provided in Section 12.2
and without the right to make the optional sinking fund payment with respect to
such series at such time.

   Any sinking fund payment or payments (mandatory or optional) made in cash
plus any unused balance of any preceding sinking fund payments made with respect
to the Securities of any particular series shall be applied by the Trustee (or
by the Company if the Company is acting as its own Paying Agent) on the sinking
fund payment date on which such payment is made (or, if such payment is made
before a sinking fund payment date, on the sinking fund payment date immediately
following the date of such payment) to the redemption of Securities of such
series at the Redemption Price specified in such Securities with respect to the
sinking fund. Any sinking fund moneys not so applied or allocated by the Trustee
(or, if the Company is acting as its own Paying Agent, segregated and held in
trust by the Company as provided in Section 10.3) for such series and together
with such payment (or such amount so segregated) shall be applied in accordance
with the provisions of this Section 12.3. Any and all sinking fund moneys with
respect to the Securities of any particular series held by the Trustee (or if
the Company is acting as its own Paying Agent, segregated and held in trust as
provided in Section 10.3) on the last sinking fund payment date with respect to
Securities of such series and not held for the payment or redemption of
particular Securities of such series shall be applied by the Trustee (or by the
Company if the Company is acting as its own Paying Agent), together with other
moneys, if necessary, to be deposited (or segregated) sufficient for the
purpose, to the payment of the principal of the Securities of such series at
Maturity. The Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 11.3 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 11.4. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Section 11.6. On or before each sinking fund payment
date, the Company shall pay to the Trustee (or, if the Company is acting as its
own Paying Agent, the Company shall segregate and hold in trust as provided in
Section 10.3) in cash a sum in the currency in which Securities of such series
are payable (except as provided pursuant to Section 3.1) equal to the principal
and any interest accrued to the Redemption Date for Securities or portions
thereof to be redeemed on such sinking fund payment date pursuant to this
Section 12.3.

   Neither the Trustee nor the Company shall redeem any Securities of a series
with sinking fund moneys or mail any notice of redemption of Securities of such
series by operation of the sinking fund for such series during the continuance
of a default in payment of interest, if any, on any Securities of such series or
of any Event of Default (other than an Event of Default occurring as a
consequence of this paragraph) with respect to the Securities of such series,
except that if the notice of redemption

                                       66
<PAGE>
 
shall have been provided in accordance with the provisions hereof, the Trustee
(or the Company, if the Company is then acting as its own Paying Agent) shall
redeem such Securities if cash sufficient for that purpose shall be deposited
with the Trustee (or segregated by the Company) for that purpose in accordance
with the terms of this Article XII. Except as aforesaid, any moneys in the
sinking fund for such series at the time when any such default or Event of
Default shall occur and any moneys thereafter paid into such sinking fund
shall, during the continuance of such default or Event of Default, be held as
security for the payment of the Securities and coupons, if any, of such series;
provided, however, that in case such default or Event of Default shall have
been cured or waived herein, such moneys shall thereafter be applied on the
next sinking fund payment date for the Securities of such series on which such
moneys may be applied pursuant to the provisions of this Section 12.3.


                                  ARTICLE XIII

                          SUBORDINATION OF SECURITIES

   Section 13.1.   Securities Subordinate to Senior Debt.

   The Company covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the payment of the principal
of (and premium, if any) and interest (including any Additional Interest) on
each and all of the Securities are hereby expressly made subordinate and subject
in right of payment to the prior payment in full of all Senior Debt.

   Section 13.2.   Payment Over of Proceeds Upon Dissolution, Etc.

   In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company (each such event, if any, herein
sometimes referred to as a "Proceeding"), then the holders of Senior Debt shall
be entitled to receive payment in full of all Allocable Amounts of such Senior
Debt, or provision shall be made for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt, before the
Holders of the Securities are entitled to receive or retain any payment or
distribution of any kind or character, whether in cash, property or securities
(including any payment or distribution which may be payable or deliverable by
reason of the payment of any other Debt of the Company (including any series of
the Securities) subordinated to the payment of the Securities, such payment or
distribution being hereinafter referred to as a "Junior Subordinated Payment"),
on account of principal of (or premium, if any) or interest (including any
Additional Interest) on the Securities or on account of the purchase or other
acquisition of Securities by the Company or any Subsidiary and to that end the
holders of Senior Debt shall be entitled to receive, for application to the
payment thereof, any payment or distribution of any kind or character, whether
in cash, property or securities, including any Junior Subordinated Payment,
which may be payable or deliverable in respect of the Securities in any such
Proceeding; provided, however, that holders of Senior Debt shall not be
entitled to receive payment of any such amounts to the extent that such holders
woud be required by the subordination provisions of such Senior Debt to pay such

                                       67
<PAGE>
 
amounts over to the obligees on trade accounts payable or other liabilities
arising in the ordinary course of the Company's business.

   In the event that, notwithstanding the foregoing provisions of this Section,
the Trustee or the Holder of any Security shall have received any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, including any Junior Subordinated Payment, before all
Allocable Amounts of all Senior Debt are paid in full or payment thereof is
provided for in cash or cash equivalents or otherwise in a manner satisfactory
to the holders of Senior Debt, and if such fact shall, at or prior to the time
of such payment or distribution, have been made known to the Trustee or, as the
case may be, such Holder, then and in such event such payment or distribution
shall be paid over or delivered forthwith to the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee, agent or other Person making
payment or distribution of assets of the Company for application to the payment
of all Allocable Amounts of all Senior Debt remaining unpaid, to the extent
necessary to pay all Allocable Amounts of all Senior Debt in full, after giving
effect to any concurrent payment or distribution to or for the holders of Senior
Debt; provided, however, that holders of Senior Debt shall not be entitled to
receive payment of any such amounts to the extent that such holders would be
required by the subordination provisions of such Senior Debt to pay such amounts
over to the obligees on trade accounts payable or other liabilities arising in
the ordinary course of the Company's business.

   For purposes of this Article only, the words "any payment or distribution of
any kind or character, whether in cash, property or securities" shall not be
deemed to include shares of stock of the Company as reorganized or readjusted,
or securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment which securities are subordinated in right of
payment to all then outstanding Senior Debt to substantially the same extent as
the Securities are so subordinated as provided in this Article. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the sale of
all or substantially all of its properties and assets as an entirety to another
Person upon the terms and conditions set forth in Article VIII shall not be
deemed a Proceeding for the purposes of this Section if the Person formed by
such consolidation or into which the Company is merged or the Person which
acquires by sale such properties and assets as an entirety, as the case may be,
shall, as a part of such consolidation, merger, or sale comply with the
conditions set forth in Article VIII.

   Section 13.3.   Prior Payment to Senior Debt Upon Acceleration of Securities.

   In the event that any Securities are declared due and payable before their
Stated Maturity, then and in such event the holders of the Senior Debt
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all Allocable Amounts due on or in
respect of such Senior Debt (including any amounts due upon acceleration), or
provision shall be made for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt, before the
Holders of the Securities are entitled to receive any payment or distribution of
any kind or character, whether in cash, properties or securities (including any
Junior Subordinated Payment) by the Company on account of the principal of (or
premium, if any) or interest (including any Additional Interest) on the

Section shall prevent the satisfaction of any sinking fund payment in

Section 3.1 for the Securities of any series by delivering and crediting
pursuant to Section 12.2 or as otherwise specified as contemplated by Section
3.1 for the Securities of any series Securities which have been acquired (upon
redemption or otherwise) prior to such declaration of acceleration; provided,
further, however, that holders of Senior Debt shall not be entitled to receive
payment of any such amounts to the extent that such holders would be required
by the subordination provisions of such Senior Debt to pay such amounts over to
the obligees on trade accounts payable or other liabilities arising in the
ordinary course of the Company's business.

   In the event that, notwithstanding the foregoing, the Company shall make any
payment to the Trustee or the Holder of any Security prohibited by the foregoing
provisions of this Section, and if such fact shall, at or prior to the time of
such payment, have been made known to the Trustee or, as the case may be, such
Holder, then and in such event such payment shall be paid over and delivered
forthwith to the Company; provided, however, that holders of Senior Debt shall
not be entitled to receive payment of any such amounts to the extent that such
holders would be required by the subordination provisions of such Senior Debt to
pay such amounts over to the obligees on trade accounts payable or other
liabilities arising in the ordinary course of the Company's business.

   The provisions of this Section shall not apply to any payment with respect to
which Section 13.2 would be applicable.

   Section 13.4.   No Payment When Senior Debt in Default.

   (a) In the event and during the continuation of any default in the payment of
principal of (or premium, if any) or interest on any Senior Debt, or in the
event that any event of default with respect to any Senior Debt shall have
occurred and be continuing and shall have resulted in such Senior Debt becoming
or being declared due and payable prior to the date on which it would otherwise
have become due and payable, unless and until such event of default shall have
been cured or waived or shall have ceased to exist and such acceleration shall
have been rescinded or annulled, or (b) in the event any judicial proceeding
shall be pending with respect to any such default in payment or such event or
default, then no payment or distribution of any kind or character, whether in
cash, properties or securities (including any Junior Subordinated Payment) shall
be made by the Company on account of principal of (or premium, if any) or
interest (including any Additional Interest), if any, on the Securities or on
account of the purchase or other acquisition of Securities by the Company or any
Subsidiary, in each case unless and until all Allocable Amounts of such Senior
Debt are paid in full; provided, however, that nothing in this Section shall
prevent the satisfaction of any sinking fund payment in accordance with this
Indenture or as otherwise specified as contemplated by Section 3.1 for the
Securities of any series by delivering and crediting pursuant to Section 12.2 or
as otherwise specified as contemplated by Section 3.1 for the Securities of any
series Securities which have been acquired (upon redemption or otherwise) prior
to such default in payment or event of default.


   In the event that, notwithstanding the foregoing, the Company shall make any
payment to the Trustee or the Holder of any Security prohibited by the foregoing
provisions of this Section, and if such fact shall, at or prior to the time of
such payment, have been made known to the Trustee or, as

                                       69
<PAGE>
 
the case may be, such Holder, then and in such event such payment shall be paid
over and delivered forthwith to the Company.

   The provisions of this Section shall not apply to any payment with respect to
which Section 13.2 would be applicable.

   Section 13.5.   Payment Permitted If No Default.

   Nothing contained in this Article or elsewhere in this Indenture or in any of
the Securities shall prevent (a) the Company, at any time except during the
pendency of any Proceeding referred to in Section 13.2 or under the conditions
described in Sections 13.3 and 13.4, from making payments at any time of
principal of (and premium, if any) or interest (including Additional Interest)
on the Securities, or (b) the application by the Trustee of any money deposited
with it hereunder to the payment of or on account of the principal of (and
premium, if any) or interest (including any Additional Interest) on the
Securities or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, it did not have knowledge that such payment
would have been prohibited by the provisions of this Article.

   Section 13.6.   Subrogation to Rights of Holders of Senior Debt.

   Subject to the payment in full of all amounts due or to become due on all
Senior Debt, or the provision for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt, the Holders of
the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Debt pursuant to the provisions
of this Article (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to Senior Debt of the Company
to substantially the same extent as the Securities are subordinated to the
Senior Debt and is entitled to like rights of subrogation by reason of any
payments or distributions made to holders of such Senior Debt) to the rights of
the holders of such Senior Debt to receive payments and distributions of cash,
property and securities applicable to the Senior Debt until the principal of
(and premium, if any) and interest on the Securities shall be paid in full. For
purposes of such subrogation, no payments or distributions to the holders of the
Senior Debt of any cash, property or securities to which the Holders of the
Securities or the Trustee would be entitled except for the provisions of this
Article, and no payments over pursuant to the provisions of this Article to the
holders of Senior Debt by Holders of the Securities or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Debt, and the
Holders of the Securities, be deemed to be a payment or distribution by the
Company to or on account of the Senior Debt.

   Section 13.7.   Provisions Solely to Define Relative Rights.

   The provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Debt on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as between the Company and the Holders of the Securities, the
obligations of the Company, which are absolute and unconditional, to pay to the
Holders of the Securities the 

                                       70
<PAGE>
 
principal of (and premium, if any) and interest (including any Additional
Interest) on the Securities as and when the same shall become due and payable
in accordance with their terms; or (b) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other
than their rights in relation to the holders of Senior Debt; or (c) prevent the
Trustee or the Holder of any Security from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture including,
without limitation, filing and voting claims in any Proceeding, subject to the
rights, if any, under this Article of the holders of Senior Debt to receive
cash, property and securities otherwise payable or deliverable to the Trustee
or such Holder.

   Section 13.8.   Trustee to Effectuate Subordination.

   Each Holder of a Security by his or her acceptance thereof authorizes and
directs the Trustee on his or her behalf to take such action as may be necessary
or appropriate to acknowledge or effectuate the subordination provided in this
Article and appoints the Trustee his or her attorney-in-fact for any and all
such purposes.

   Section 13.9.   No Waiver of Subordination Provisions.

   No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof that any such holder may have or be
otherwise charged with.

   Without in any way limiting the generality of the immediately preceding
paragraph, the holders of Senior Debt may, at any time and from to time, without
the consent of or notice to the Trustee or the Holders of the Securities,
without incurring responsibility to the Holders of the Securities and without
impairing or releasing the subordination provided in this Article or the
obligations hereunder of the Holders of the Securities to the holders of Senior
Debt, do any one or more of the following:  (i) change the manner, place or
terms of payment or extend the time of payment of, or renew or alter, Senior
Debt, or otherwise amend or supplement in any manner Senior Debt or any
instrument evidencing the same or any agreement under which Senior Debt is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Debt; (iii) release any Person
liable in any manner for the collection of Senior Debt; and (iv) exercise or
refrain from exercising any rights against the Company and any other Person.

   Section 13.10.    Notice to Trustee.

   The Company shall give prompt written notice to the Trustee of any fact known
to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Debt or from any trustee, agent or representative
therefor; provided, however, that if the Trustee shall not have received 

                                       71
<PAGE>
 
the notice provided for in this Section at least two Business Days prior to the
date upon which by the terms hereof any monies may become payable for any
purpose (including, without limitation, the payment of the principal of (and
premium, if any) or interest (including any Additional Interest) on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such monies and to apply
the same to the purpose for which they were received and shall not be affected
by any notice to the contrary which may be received by it within two Business
Days prior to such date.

   Subject to the provisions of Section 6.1, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
to be a holder of Senior Debt (or a trustee therefor) to establish that such
notice has been given by a holder of Senior Debt (or a trustee therefor). In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of Senior Debt held by such Person, the extent to
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article, and
if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

   Section 13.11.    Reliance on Judicial Order or Certificate of Liquidating
Agent.

   Upon any payment or distribution of assets of the Company referred to in this
Article, the Trustee, subject to the provisions of Section 6.1, and the Holders
of the Securities shall be entitled to rely upon any order or decree entered by
any court of competent jurisdiction in which such Proceeding is pending, or a
certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the Holders of
Securities, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article.

   Section 13.12.    Trustee Not Fiduciary for Holders of Senior Debt.

   The Trustee, in its capacity as trustee under this Indenture, shall not be
deemed to owe any fiduciary duty to the holders of Senior Debt and shall not be
liable to any such holders if it shall in good faith mistakenly pay over or
distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article or otherwise.



   Section 13.13.    Rights of Trustee as Holder of Senior Debt; Preservation of
Trustee's Rights.

   The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Debt which may at any time
be held by it, to the same extent as any other 

                                       72
<PAGE>
 
holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee
of any of its rights as such holder.

   Section 13.14.    Article Applicable to Paying Agents.

   In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context otherwise requires)
be construed as extending to and including such Paying Agent within its meaning
as fully for all intents and purposes as if such Paying Agent were named in this
Article in addition to or in place of the Trustee.

   Section 13.15.    Certain Conversions or Exchanges Deemed Payment.

   For the purposes of this Article only, (a) the issuance and delivery of
junior securities upon conversion or exchange of Securities shall not be deemed
to constitute a payment or distribution on account of the principal of (or
premium, if any) or interest (including any Additional Interest) on Securities
or on account of the purchase or other acquisition of Securities, and (b) the
payment, issuance or delivery of cash, property or securities (other than junior
securities) upon conversion or exchange of a Security shall be deemed to
constitute payment on account of the principal of such security. For the
purposes of this Section, the term "junior securities" means (i) shares of any
stock of any class of the Company and (ii) securities of the Company which are
subordinated in right of payment to all Senior Debt which may be outstanding at
the time of issuance or delivery of such securities to substantially the same
extent as, or to a greater extent than, the Securities are so subordinated as
provided in this Article.

so executed shall be deemed to be an original, but all such counterparts shall

          to the terms of this Trust Agreement and protect and conserve the
          Trust Property for the benefit of the Securityholders (without
          consideration of the effect of any such action on any particular

in their capacity as Securityholders.

     (d) Notwithstanding anything herein to the contrary, the Administrative
Trustees are authorized and directed to conduct the affairs of the Trust and to
operate the Trust so that the Trust will not be deemed to be an "investment
company" required to be registered under the 1940 Act, or to be classified as an
association taxable as a corporation or as other than a grantor trust for United
States Federal income tax purposes and so that the Debentures will be treated as
indebtedness of the Depositor for United States Federal income tax purposes. In
this connection, the Depositor and the Administrative Trustees are authorized to
take any action, not inconsistent with applicable law, the Certificate of Trust
or this Trust Agreement, that each of the Depositor and any Administrative
Trustee determines in its discretion to be necessary or desirable for such
purposes, as long as such action does not adversely affect in any material
respect the interests of the holders of the Preferred Securities.

subject to) any priority of payments provided for herein.

     (b) The Property Trustee shall deposit in the Payment Account, promptly

                           Distributions; Redemption

          Section 4.1. Distributions.

          (a) The Trust Securities represent undivided beneficial interests in
the Trust Property, and Distributions (including of Additional Amounts) will be
made on the Trust Securities at the rate and on the dates that payments of
interest (including of Additional Interest, as defined in the Indenture) are
made on the Debentures.  Accordingly:

          (i) Distributions on the Trust Securities shall be cumulative, and
     will accumulate whether or not there are funds of the Trust available for
     the payment of Distributions. Distributions shall accrue from December __,
     1996, and, except in the event (and to the extent) that the Depositor
     exercises its right to defer the payment of interest on the Debentures
     pursuant to the Indenture, shall be payable quarterly in arrears on March
     31, June 30, September 30 and December 31 of each year, commencing on March
     31, 1997. If any date on which a Distribution is otherwise payable on the
     Trust Securities is not a Business Day, then the payment of such
     Distribution shall be made on the next succeeding day that is a Business
     Day (and without any interest or other payment in respect of any such
     delay) except that, if such Business Day is in the next succeeding calendar
     year, payment of such Distribution shall be made on the immediately
     preceding Business Day, in each case with the same force and effect as if
     made on such date (each date on which distributions are payable in
     accordance with this Section 4.1(a), a "Distribution Date").

          (ii) Assuming payments of interest on the Debentures are made when due
     (and before giving effect to Additional Amounts, if applicable), the Trust
     Securities will be entitled to preferred Distributions payable at a rate of
     ____% per annum of the Liquidation Amount of the Trust Securities. The
     amount of Distributions payable for any full period shall be computed on
     the basis of a 360-day year of twelve 30-day months. The amount of
     Distributions for any partial period shall be computed on the basis of the
     number of days elapsed in a 360-day year of twelve 30-day months. The
     amount of Distributions payable for any period shall include the Additional
     Amounts, if any.

          (iii) Distributions on the Trust Securities shall be made by the
     Property Trustee from the Payment Account and shall be payable on each
     Distribution Date only to the extent that the Trust has funds then on hand
     and available in the Payment Account for the payment of such Distributions.

     (b) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which shall be
one Business Day prior to such Distribution Date; provided, however, that in the
event that the Preferred Securities do not remain in book-entry-

                                       17
<PAGE>
 
only form, the relevant record date shall be the date 15 days prior to the
relevant Distribution Date.

     Section 4.2. Redemption.

     (a) On each Debenture Redemption Date and on the stated maturity of the
Debentures, the Trust will be required to redeem a Like Amount of Trust
Securities at the Redemption Price.

     (b) Notice of redemption shall be given by the Property Trustee by first-
class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior
to the Redemption Date to each Holder of Trust Securities to be redeemed, at
such Holder's address appearing in the Security Register. All notices of
redemption shall state:

          (i) the Redemption Date;

          (ii) the Redemption Price;

          (iii) the CUSIP number;

          (iv) if less than all the Outstanding Trust Securities are to be
     redeemed, the identification and the total Liquidation Amount of the
     particular Trust Securities to be redeemed; and

          (v) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Trust Security to be redeemed and that
     Distributions thereon will cease to accrue on and after said date.

     (c) The Trust Securities redeemed on each Redemption Date shall be redeemed
at the Redemption Price with the proceeds from the contemporaneous redemption of
Debentures. Redemptions of the Trust Securities shall be made and the Redemption
Price shall be payable on each Redemption Date only to the extent that the Trust
has funds then on hand and available in the Payment Account for the payment of
such Redemption Price.

     (d) If the Property Trustee gives a notice of redemption in respect of any
Preferred Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), the Property Trustee will, so long as the
Preferred Securities are in book-entry-only form, irrevocably deposit with the
Clearing Agency for the Preferred Securities funds sufficient to pay the
applicable Redemption Price and will give such Clearing Agency irrevocable
instructions and authority to pay the Redemption Price to the holders thereof.
If the Preferred Securities are no longer in book-entry-only form, the Property
Trustee, subject to Section 4.2(c), will irrevocably deposit with the Paying
Agent funds sufficient to pay the applicable Redemption Price and will give the
Paying Agent irrevocable instructions and authority to pay the Redemption Price
to the Holders thereof upon surrender of their Preferred Securities
Certificates. Notwithstanding the foregoing, Distributions payable on or prior
to the Redemption

                                       18
<PAGE>
 
Date for any Trust Securities called for redemption shall be payable to the
Holders of such Trust Securities as they appear on the Register for the Trust
Securities on the relevant record dates for the related Distribution Dates. If
notice of redemption shall have been given and funds deposited as required, then
upon the date of such deposit, all rights of Securityholders holding Trust
Securities so called for redemption will cease, except the right of such
Securityholders to receive the Redemption Price and any Distribution payable on
or prior to the Redemption Date, but without interest, and such Securities will
cease to be outstanding. In the event that any date on which any Redemption
Price is payable is not a Business Day, then payment of the Redemption Price
payable on such date will be made on the next succeeding day that is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day falls in the next calendar year, such payment
will be made on the immediately preceding Business Day, in each case, with the
same force and effect as if made on such date. In the event that payment of the
Redemption Price in respect of any Trust Securities called for redemption is
improperly withheld or refused and not paid either by the Trust or by the
Depositor pursuant to the Guarantee, Distributions on such Trust Securities will
continue to accrue, at the then applicable rate, from the Redemption Date
originally established by the Trust for such Trust Securities to the date such
Redemption Price is actually paid, in which case the actual payment date will be
the date fixed for redemption for purposes of calculating the Redemption Price.

     (e) Payment of the Redemption Price on the Trust Securities shall be made
to the recordholders thereof as they appear on the Securities Register for the
Trust Securities on the relevant record date, which shall be one Business Day
prior to the relevant Redemption Date; provided, however, that in the event that
the Preferred Securities do not remain in book-entry-only form, the relevant
record date shall be the date fifteen days prior to the relevant Redemption
Date.

     (f) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities. The particular Preferred Securities to be redeemed
shall be selected on a pro rata basis (based upon Liquidation Amounts) not more
than 60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Preferred Securities not previously called for redemption, by such
method (including, without limitation, by lot) as the Property Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to $25 or an integral multiple of $25 in excess thereof) of
the Liquidation Amount of Preferred Securities of a denomination larger than
$25. The Property Trustee shall promptly notify the Security Registrar in
writing of the Preferred Securities selected for redemption and, in the case of
any Preferred Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed. For all purposes of this Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of
Preferred Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed.

     Section 4.3. Subordination of Common Securities.

                                       19
<PAGE>
 
     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made, subject to Section 4.2(f), pro rata among the Common Securities and the
Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities, shall have
been made or provided for, and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

     (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holder of Common Securities will be deemed
to have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated.
Until any such Event of Default under this Trust Agreement with respect to the
Preferred Securities has been so cured, waived or otherwise eliminated, the
Property Trustee shall act solely on behalf of the Holders of the Preferred
Securities and not the Holder of the Common Securities, and only the Holders of
the Preferred Securities will have the right to direct the Property Trustee to
act on their behalf.

     Section 4.4. Payment Procedures.

     Payments of Distributions (including Additional Amounts, if applicable) in
respect of the Preferred Securities shall be made by check mailed to the address
of the Person entitled thereto as such address shall appear on the Securities
Register or, if the Preferred Securities are held by a Clearing Agency, such
Distributions shall be made to the Clearing Agency in immediately available
funds, which shall credit the relevant Persons' accounts at such Clearing Agency
on the applicable Distribution Dates. Payments in respect of the Common
Securities shall be made in such manner as shall be mutually agreed between the
Property Trustee and the Common Securityholder.

     Section 4.5. Tax Returns and Reports.

     The Administrative Trustees shall prepare (or cause to be prepared), at the
Depositor's expense, and file all United States Federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared and filed) the appropriate Internal Revenue Service
Form required to be filed in respect of the Trust in each taxable year of the
Trust and (b) prepare and furnish (or cause to be prepared and furnished) to
each Securityholder

                                       20
<PAGE>
 
the appropriate Internal Revenue Service form required to be provided on such
form. The Administrative Trustees shall provide the Depositor and the Property
Trustee with a copy of all such returns and reports promptly after such filing
or furnishing. The Trustees shall comply with United States Federal withholding
and backup withholding tax laws and information reporting requirements with
respect to any payments to Securityholders under the Trust Securities.

     Section 4.6. Payment of Taxes, Duties, Etc. of the Trust.

     Upon receipt under the Debentures of Additional Sums, the Property Trustee
shall promptly pay any taxes, duties or governmental charges of whatsoever
nature (other than withholding taxes) imposed on the Trust by the United States
or any other taxing authority.

     Section 4.7. Payments under Indenture or Pursuant to Direct Actions.

     Any amount payable hereunder to any Holder of Preferred Securities (and any
Owner with respect thereto) shall be reduced by the amount of any corresponding
payment such Holder (and Owner) has directly received pursuant to Section 5.8 of
the Indenture or Section 5.14 of this Trust Agreement.

     Section 4.8. Liability of the Holder of Common Securities.

     The Holder of Common Securities shall be liable for the debts and
obligations of the Trust as set forth in the Expense Agreement.

     Section 5.1. Initial Ownership.

     Upon the formation of the Trust and the contribution by the Depositor
pursuant to Section 2.3 and until the issuance of the Trust Securities, and at
any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

     Section 5.2. The Trust Securities Certificates.

     The Preferred Securities Certificates shall be issued in minimum
denominations of $25 Liquidation Amount and integral multiples of $25 in excess
thereof, and the Common Securities Certificates shall be issued in denominations
of $25 Liquidation Amount and integral multiples thereof. The Trust Securities
Certificates shall be executed on behalf of the Trust by manual signature of at
least one Administrative Trustee. Trust Securities Certificates bearing the
manual signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Trust, shall be
validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or any of them shall have ceased to

                                       21

Certificates. A transferee of a Trust Securities Certificate shall become a
Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.11
and 5.13.

     Section 5.3. Execution and Delivery of Trust Securities Certificates.

     At each Time of Delivery, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its chairman of the board,
its president, any executive vice president or any vice president, treasurer or
assistant treasurer or controller without further corporate action by the
Depositor, in authorized denominations.

     Section 5.4. Registration of Transfer and Exchange of Preferred Securities
Certificates.

     The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (the "Securities Register") in which, the
registrar designated by the Depositor (the "Securities Registrar"), subject to
such reasonable regulations as it may prescribe, shall provide for the
registration of Preferred Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided. The Bank shall be the initial
Securities Registrar.

     Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or agency maintained pursuant to Section 5.8, the
Administrative Trustees or any one of them shall execute and deliver, in the
name of the designated transferee or transferees, one or more new Preferred
Securities Certificates in authorized denominations of a like aggregate
Liquidation Amount dated the date of execution by such Administrative Trustee or
Trustees.

     The Securities Registrar shall not be required to register the transfer of
any Preferred Securities that have been called for redemption. At the option of
a Holder, Preferred Securities Certificates may be exchanged for other Preferred
Securities Certificates in authorized denominations of the same class and of a
like aggregate Liquidation Amount upon surrender of the Preferred Securities
Certificates to be exchanged at the office or agency maintained pursuant to
Section 5.8.

     Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to an Administrative Trustee and the
Securities Registrar duly executed by the Holder or his attorney duly authorized
in writing. Each Preferred Securities Certificate surrendered for registration
of transfer or exchange shall be cancelled and subsequently disposed of by an
Administrative Trustee in accordance with such Person's customary practice.

                                       22
<PAGE>
 
     No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but the Securities Registrar may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Preferred
Securities Certificates.

     Section 5.5. Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates.

     If (a) any mutilated Trust Securities Certificate shall be surrendered to
the Securities Registrar, or if the Securities Registrar shall receive evidence
to its satisfaction of the destruction, loss or theft of any Trust Securities
Certificate and (b) there shall be delivered to the Securities Registrar and the
Administrative Trustees such security or indemnity as may be required by them to
save each of them harmless, then in the absence of notice that such Trust
Securities Certificate shall have been acquired by a bona fide purchaser, the
Administrative Trustees, or any one of them, on behalf of the Trust shall
execute and make available for delivery, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust
Securities Certificate of like class, tenor and denomination. In connection with
the issuance of any new Trust Securities Certificate under this Section, the
Administrative Trustees or the Securities Registrar may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection therewith. Any duplicate Trust Securities Certificate issued
pursuant to this Section shall constitute conclusive evidence of an undivided
beneficial interest in the assets of the Trust, as if originally issued, whether
or not the lost, stolen or destroyed Trust Securities Certificate shall be found
at any time.

     Section 5.6. Persons Deemed Securityholders.

     The Trustees or the Securities Registrar shall treat the Person in whose
name any Trust Securities Certificate shall be registered in the Securities
Register as the owner of such Trust Securities Certificate for the purpose of
receiving Distributions and for all other purposes whatsoever, and neither the
Trustees nor the Securities Registrar shall be bound by any notice to the
contrary.

     Section 5.7. Access to List of Securityholders' Names and Addresses.

     Each Holder and each Owner shall be deemed to have agreed not to hold the
Depositor, the Property Trustee or the Administrative Trustees accountable by
reason of the disclosure of its name and address, regardless of the source from
which such information was derived.

     Section 5.8. Maintenance of Office or Agency.

     The Administrative Trustees shall maintain an office or offices or agency
or agencies where Preferred Securities Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Trustees in respect of the Trust Securities Certificates may be served. The
Administrative Trustees initially designate Mellon Bank Corporation, One Mellon
Bank Center, 500 Grant Street, Pittsburgh, Pennsylvania 15258,

                                       23
<PAGE>
 
Attn: Secretary, as its principal corporate trust office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor and to
the Securityholders of any change in the location of the Securities Register or
any such office or agency.

     Section 5.9. Appointment of Paying Agent.

     The Paying Agent shall make distributions to Securityholders from the
Payment Account and shall report the amounts of such distributions to the
Property Trustee and the Administrative Trustees. Any Paying Agent shall have
the revocable power to withdraw funds from the Payment Account for the purpose
of making the distributions referred to above. The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Bank, and any co-paying agent chosen by the Bank, and
acceptable to the Administrative Trustees and the Depositor. Any Person acting
as Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Administrative Trustees, the Property Trustee and the
Depositor. In the event that the Bank shall no longer be the Paying Agent or a
successor Paying Agent shall resign or its authority to act be revoked, the
Administrative Trustees shall appoint a successor that is acceptable to the
Property Trustee and the Depositor to act as Paying Agent (which shall be a bank
or trust company). The Administrative Trustees shall cause such successor Paying
Agent or any additional Paying Agent appointed by the Administrative Trustees to
execute and deliver to the Trustees an instrument in which such successor Paying
Agent or additional Paying Agent shall agree with the Trustees that as Paying
Agent, such successor Paying Agent or additional Paying Agent will hold all
sums, if any, held by it for payment to the Securityholders in trust for the
benefit of the Securityholders entitled thereto until such sums shall be paid to
such Securityholders. The Paying Agent shall return all unclaimed funds to the
Property Trustee and upon removal of a Paying Agent such Paying Agent shall also
return all funds in its possession to the Property Trustee. The provisions of
Sections 8.1, 8.3 and 8.6 herein shall apply to the Bank also in its role as
Paying Agent, for so long as the Bank shall act as Paying Agent and, to the
extent applicable, to any other paying agent appointed hereunder. Any reference
in this Agreement to the Paying Agent shall include any co-paying agent unless
the context requires otherwise.

     Section 5.10. Ownership of Common Securities by Depositor.

     At each Time of Delivery, the Depositor shall acquire and retain beneficial
and record ownership of the Common Securities. To the fullest extent permitted
by law, other than a transfer in connection with a consolidation or merger of
the Depositor into another corporation, or any conveyance, transfer or lease by
the Depositor of its properties and assets substantially as an entirety to any
Person, pursuant to Section 8.1 of the Indenture, any attempted transfer of the
Common Securities shall be void. The Administrative Trustees shall cause each

     Section 5.11. Book-Entry Preferred Securities Certificates; Common
Securities Certificate.

     (a) The Preferred Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to The Depository Trust Company, the initial Clearing Agency, by, or
on behalf of, the Trust. Such Preferred Securities Certificate or Certificates
shall initially be registered on the Securities Register in the name of Cede &
Co., the nominee of the initial Clearing Agency, and no Owner will receive a
Definitive Preferred Securities Certificate representing such Owner's interest
in such Preferred Securities, except as provided in Section 5.13. Unless and
until Definitive Preferred Securities Certificates have been issued to Owners
pursuant to Section 5.13:

          (i) the provisions of this Section 5.11(a) shall be in full force and
     effect;

          (ii) the Securities Registrar and the Trustees shall be entitled to
     deal with the Clearing Agency for all purposes of this Trust Agreement
     relating to the Book-Entry Preferred Securities Certificates (including the
     payment of the Liquidation Amount of and Distributions on the Preferred
     Securities evidenced by Book-Entry Preferred Securities Certificates and
     the giving of instructions or directions to Owners of Preferred Securities
     evidenced by Book-Entry Preferred Securities Certificates) as the sole
     Holder of Preferred Securities evidenced by Book-Entry Preferred Securities
     Certificates and shall have no obligations to the Owners thereof;

          (iii) to the extent that the provisions of this Section 5.11 conflict
     with any other provisions of this Trust Agreement, the provisions of this
     Section 5.11 shall control; and

          (iv) the rights of the Owners of the Book-Entry Preferred Securities
     Certificates shall be exercised only through the Clearing Agency and shall
     be limited to those established by law and agreements between such Owners
     and the Clearing Agency and/or the Clearing Agency Participants. Pursuant
     to the Certificate Depository Agreement, unless and until Definitive
     Preferred Securities Certificates are issued pursuant to Section 5.13, the
     initial Clearing Agency will make book-entry transfers among the Clearing
     Agency Participants and receive and transmit payments on the Preferred
     Securities to such Clearing Agency Participants.

     (b) A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

     Section 5.12. Notices to Clearing Agency.

     To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and

                                       25
<PAGE>
 
communications specified herein to be given to Owners to the Clearing Agency,
and shall have no obligations to the Owners.

     Section 5.13. Definitive Preferred Securities Certificates.

     If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Preferred Securities Certificates, and the Depositor is
unable to locate a qualified successor, (b) the Depositor at its option advises
the Trustees in writing that it elects to terminate the book-entry system
through the Clearing Agency or (c) after the occurrence of a Debenture Event of
Default, Owners of Preferred Securities Certificates representing beneficial
interests aggregating at least a majority of the Liquidation Amount advise the
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Administrative Trustee shall notify
the Clearing Agency and the Clearing Agency shall notify all Owners of Preferred
Securities Certificates and the other Trustees of the occurrence of any such
event and of the availability of the Definitive Preferred Securities
Certificates to Owners of such class or classes, as applicable, requesting the
same. Upon surrender to the Administrative Trustees of the typewritten Preferred
Securities Certificate or Certificates representing the Book Entry Preferred
Securities Certificates by the Clearing Agency, accompanied by registration
instructions, the Administrative Trustees, or any one of them, shall execute the
Definitive Preferred Securities Certificates in accordance with the instructions
of the Clearing Agency. Neither the Securities Registrar nor the Trustees shall
be liable for any delay in delivery of such instructions and may conclusively
rely on, and shall be protected in relying on, such instructions. Upon the
issuance of Definitive Preferred Securities Certificates, the Trustees shall
recognize the Holders of the Definitive Preferred Securities Certificates as
Securityholders. The Definitive Preferred Securities Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidenced by the
execution thereof by the Administrative Trustees or any one of them.

     Section 5.14. Rights of Securityholders.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the Trust. The Holders of the Trust Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

                                       26

     (b) For so long as any Preferred Securities remain Outstanding, if, upon a
Debenture Event of Default, the Debenture Trustee fails or the holders of not
less than 25% in principal amount of the outstanding Debentures fail to declare
the principal of all of the Debentures to be immediately due and payable, the
Holders of at least 25% in Liquidation Amount of the Preferred Securities then
Outstanding shall have such right by a notice in writing to the Depositor and
the Debenture Trustee; and upon any such declaration such principal amount of
and the accrued interest on all of the Debentures shall become immediately due
and payable, provided that the payment of principal and interest on such
Debentures shall remain subordinated to the extent provided in the Indenture.

     At any time after such a declaration of acceleration with respect to the
Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as in the Indenture
provided, the Holders of a majority in Liquidation Amount of the Preferred
Securities, by written notice to the Property Trustee, the Depositor and the
Debenture Trustee, may rescind and annul such declaration and its consequences
if:

          (i) the Depositor has paid or deposited with the Debenture Trustee a
     sum sufficient to pay

               (A) all overdue installments of interest (including any
          Additional Interest (as defined in the Indenture)) on all of the
          Debentures,

               (B) the principal of (and premium, if any, on) any Debentures
          which have become due otherwise than by such declaration of
          acceleration and interest thereon at the rate borne by the Debentures,
          and

               (C) all sums paid or advanced by the Debenture Trustee under the
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Debenture Trustee and the Property Trustee, their
          agents and counsel; and

          (ii) all Events of Default with respect to the Debentures, other than
     the non-payment of the principal of the Debentures which has become due
     solely by such acceleration, have been cured or waived as provided in
     Section 5.13 of the Indenture.

     The holders of a majority in aggregate liquidation preference of the
Preferred Securities may, on behalf of the Holders of all the Preferred
Securities, waive any past default under the Indenture, except a default in the
payment of principal or interest (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee) or
a default in respect of a covenant or provision which under the Indenture cannot
be modified or amended without the consent of the holder of each outstanding
Debenture. No such rescission shall affect any subsequent default or impair any
right consequent thereon.

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of the Preferred
Securities all or part of which

                                       27
<PAGE>
 
is represented by Book-Entry Preferred Securities Certificates, a record date
shall be established for determining Holders of Outstanding Preferred Securities
entitled to join in such notice, which record date shall be at the close of
business on the day the Property Trustee receives such notice. The Holders on
such record date, or their duly designated proxies, and only such Persons, shall
be entitled to join in such notice, whether or not such Holders remain Holders
after such record date; provided, that, unless such declaration of acceleration,
or rescission and annulment, as the case may be, shall have become effective by
virtue of the requisite percentage having joined in such notice prior to the day
which is 90 days after such record date, such notice of declaration of
acceleration, or rescission and annulment, as the case may be, shall
automatically and without further action by any Holder be canceled and of no
further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of
a Holder, from giving, after expiration of such 90-day period, a new written
notice of declaration of acceleration, or rescission and annulment thereof, as
the case may be, that is identical to a written notice which has been canceled
pursuant to the proviso to the preceding sentence, in which event a new record
date shall be established pursuant to the provisions of this Section 5.14(b).

     (c) For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section 5.1(1)
or 5.1(2) of the Indenture, any Holder of Preferred Securities shall have the
right to institute a proceeding directly against the Depositor, pursuant to
Section 5.8 of the Indenture, for enforcement of payment to such Holder of the
principal amount of or interest on Debentures having a principal amount equal to
the Liquidation Amount of the Preferred Securities of such Holder (a "Direct
Action"). Except as set forth in Section 5.14(b) and this Section 5.14(c), the
Holders of Preferred Securities shall have no right to exercise directly any
right or remedy available to the holders of, or in respect of, the Debentures.


                                  ARTICLE VI.

                   Acts of Securityholders; Meetings; Voting

     Section 6.1. Limitations on Voting Rights.

     (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 and
in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 5.13 of

                                       28
<PAGE>
 
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the Debentures,
where such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of at least a majority in Liquidation Amount of all
Outstanding Preferred Securities, provided, however, that where a consent under
the Indenture would require the consent of each Holder of Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior written consent of each Holder of Preferred Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of Preferred Securities, except by a subsequent vote of the Holders of Preferred
Securities. The Property Trustee shall notify all Holders of the Preferred
Securities of any notice of default received from the Debenture Trustee with
respect to the Debentures. In addition to obtaining the foregoing approvals of
the Holders of the Preferred Securities, prior to taking any of the foregoing
actions, the Trustees shall, at the expense of the Depositor, obtain an Opinion
of Counsel experienced in such matters to the effect that such action shall not
cause the Trust to be classified as an association taxable as a corporation or
as other than a grantor trust for United States Federal income tax purposes.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in Liquidation
Amount of the Outstanding Preferred Securities. Notwithstanding any other
provision of this Trust Agreement, no amendment to this Trust Agreement may be
made if, as a result of such amendment, it would cause the Trust to be
classified as an association taxable as a corporation or as other than a grantor
trust for United States Federal income tax purposes.

     Section 6.2. Notice of Meetings.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.

     Section 6.3. Meetings of Preferred Securityholders.

     No annual meeting of Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of Preferred
Securityholders to vote on any matter upon the written request of the Preferred
Securityholders of record of 25% of the Preferred Securities (based upon their
Liquidation Amount) and the Administrative Trustees or the Property Trustee

                                       29
<PAGE>
 
may, at any time in their discretion, call a meeting of Preferred
Securityholders to vote on any matters as to which Preferred Securityholders are
entitled to vote.

     Preferred Securityholders of record of 50% of the Outstanding Preferred
Securities (based upon their Liquidation Amount), present in person or by proxy,
shall constitute a quorum at any meeting of Securityholders.

     If a quorum is present at a meeting, an affirmative vote by the Preferred
Securityholders of record present, in person or by proxy, holding more than a
majority of the Preferred Securities (based upon their Liquidation Amount) held
by the Preferred Securityholders of record present, either in person or by
proxy, at such meeting shall constitute the action of the Preferred
Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

     Section 6.4. Voting Rights.

     Securityholders shall be entitled to one vote for each $25 of Liquidation
Amount represented by their Trust Securities in respect of any matter as to
which such Securityholders are entitled to vote.

     Section 6.5. Proxies, etc.

     At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of the Property Trustee, proxies may be solicited in
the name of the Property Trustee or one or more officers of the Property
Trustee. Only Securityholders of record shall be entitled to vote. When Trust
Securities are held jointly by several persons, any one of them may vote at any
meeting in person or by proxy in respect of such Trust Securities, but if more
than one of them shall be present at such meeting in person or by proxy, and
such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Trust Securities. A
proxy purporting to be executed by or on behalf of a Securityholder shall be
deemed valid unless challenged at or prior to its exercise, and the burden of
proving invalidity shall rest on the challenger. No proxy shall be valid more
than three years after its date of execution.

     Section 6.6. Securityholder Action by Written Consent.

     Any action which may be taken by Securityholders at a meeting may be taken
without a meeting if Securityholders holding more than a majority of all
Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

     Section 6.7. Record Date for Voting and Other Purposes.

                                       30
<PAGE>
 
     For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative Trustees may from time to time fix a date, not
more than 90 days prior to the date of any meeting of Securityholders or the
payment of a distribution or other action, as the case may be, as a record date
for the determination of the identity of the Securityholders of record for such
purposes.

     Section 6.8. Acts of Securityholders.

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Trust Agreement to be given, made or
taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders or
Owners signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 8.1) conclusive in favor
of the Trustees, if made in the manner provided in this Section.

     The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which any Trustee receiving the same deems sufficient.

     The ownership of Preferred Securities shall be proved by the Securities
Register.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

     Without limiting the foregoing, a Securityholder entitled hereunder to take
any action hereunder with regard to any particular Trust Security may do so with
regard to all or any part of the Liquidation Amount of such Trust Security or by
one or more duly appointed agents each

                                       31
<PAGE>
 
of which may do so pursuant to such appointment with regard to all or any part
of such liquidation amount.

     If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.

     A Securityholder may institute a legal proceeding directly against the
Depositor under the Guarantee to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee (as defined
in the Guarantee), the Trust or any person or entity.

     Section 6.9. Inspection of Records.

     Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection by Securityholders
during normal business hours for any purpose reasonably related to such
Securityholder's interest as a Securityholder.

                         Representations and Warranties

     Section 7.1. Representations and Warranties of the Property Trustee and the
Delaware Trustee.

     The Property Trustee and the Delaware Trustee, each severally on behalf of
and as to itself, hereby represents and warrants for the benefit of the

similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles;

Trustee or the Delaware Trustee is a party or by which it is bound, or (iii)
violate any law, governmental rule or regulation of the United States or the
State of Delaware, as the case may be, governing the banking, trust or general

context) or any order, judgment or decree applicable to the Property Trustee or
the Delaware Trustee;

     (g) neither the authorization, execution or delivery by the Property

other action with respect to any governmental authority or agency under any
existing Federal law governing the banking, trust or general powers of the
Property Trustee or the Delaware Trustee, as the case may be, under the laws of
the United States or the State of Delaware;

Property Trustee's and the Delaware Trustee's knowledge, threatened against or
affecting the Property Trustee or the Delaware Trustee in any court or before

individually or in the aggregate, would materially and adversely affect the
Trust or would question the right, power and authority of the Property Trustee
or the Delaware Trustee, as the case may be, to enter into or perform its
obligations as one of the Trustees under this Trust Agreement.

     Section 7.2. Representations and Warranties of Depositor.

     The Depositor hereby represents and warrants for the benefit of the
Securityholders that:

     (a) the Trust Securities Certificates issued at each Time of Delivery on

validly executed, issued and delivered by the Trustees pursuant to the terms and
provisions of, and in accordance with the requirements

                                       33
<PAGE>
 
of, this Trust Agreement and the Securityholders will be, as of each such date,
entitled to the benefits of this Trust Agreement; and

     (b) there are no taxes, fees or other governmental charges payable by the
Trust (or the Trustees on behalf of the Trust) under the laws of the State of
Delaware or any political subdivision thereof in connection with the execution,
delivery and performance by the Property Trustee or the Delaware Trustee, as the
case may be, of this Trust Agreement.


                                 ARTICLE VIII.

                                  The Trustees

     Section 8.1. Certain Duties and Responsibilities.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, by the Trust
Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it. Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Trustees shall be subject to the provisions of this Section.
Nothing in this Trust Agreement shall be construed to release an Administrative
Trustee from liability for its own gross negligent action, its own gross
negligent failure to act, or its own willful misconduct. To the extent that, at
law or in equity, an Administrative Trustee has duties (including fiduciary
duties) and liabilities relating thereto to the Trust or to the Securityholders,
such Administrative Trustee shall not be liable to the Trust or to any
Securityholder for such Trustee's good faith reliance on the provisions of this
Trust Agreement. The provisions of this Trust Agreement, to the extent that they
restrict the duties and liabilities of the Administrative Trustees otherwise
existing at law or in equity, are agreed by the Depositor and the
Securityholders to replace such other duties and liabilities of the
Administrative Trustees.

     (b) All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the Property Trustee or a Paying
Agent to make payments in accordance with the terms hereof. Each Securityholder,
by its acceptance of a Trust Security, agrees that it will look solely to the
revenue and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that the Trustees are not personally
liable to it for any amount distributable in respect of any Trust Security or
for any other liability in respect of any Trust Security. This Section 8.1(b)
does not limit the liability of the Trustees expressly set forth elsewhere in
this Trust Agreement or, in the case of the Property Trustee, in the Trust
Indenture Act.

                                       34
<PAGE>
 
     (c) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

          (i) the Property Trustee shall not be liable for any error of judgment
     made in good faith by an authorized officer of the Property Trustee, unless
     it shall be proved that the Property Trustee was negligent in ascertaining
     the pertinent facts;

          (ii) the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of not less than a majority in Liquidation
     Amount of the Trust Securities relating to the time, method and place of
     conducting any proceeding for any remedy available to the Property Trustee,
     or exercising any trust or power conferred upon the Property Trustee under
     this Trust Agreement;

          (iii) the Property Trustee's sole duty with respect to the custody,
     safe keeping and physical preservation of the Debentures and the Payment
     Account shall be to deal with such Property in a similar manner as the
     Property Trustee deals with similar property for its own account, subject
     to the protections and limitations on liability afforded to the Property
     Trustee under this Trust Agreement and the Trust Indenture Act;

          (iv) the Property Trustee shall not be liable for any interest on any
     money received by it except as it may otherwise agree with the Depositor;
     and money held by the Property Trustee need not be segregated from other
     funds held by it except in relation to the Payment Account maintained by
     the Property Trustee pursuant to Section 3.1 and except to the extent
     otherwise required by law; and

          (v) the Property Trustee shall not be responsible for monitoring the
     compliance by the Administrative Trustees or the Depositor with their
     respective duties under this Trust Agreement, nor shall the Property
     Trustee be liable for the default or misconduct of the Administrative
     Trustees or the Depositor.

     Section 8.2. Certain Notices.

          Within five Business Days after the occurrence of any Event of Default
     actually known to the Property Trustee, the Property Trustee shall
     transmit, in the manner and to the extent provided in Section 10.8, notice
     of such Event of Default to the Securityholders, the Administrative
     Trustees and the Depositor, unless such Event of Default shall have been
     cured or waived.

          Within five Business Days after the receipt of notice of the
     Depositor's exercise of its right to defer the payment of interest on the
     Debentures pursuant to the Indenture, the Administrative Trustee shall
     transmit, in the manner and to the extent provided in Section 10.8, notice
     of such exercise to the Securityholders and the Property Trustee, unless
     such exercise shall have been revoked.

          Section 8.3. Certain Rights of Property Trustee.

          Subject to the provisions of Section 8.1:

          (a) the Property Trustee may rely and shall be protected in acting or
     refraining from acting in good faith upon any resolution, Opinion of
     Counsel, certificate, written representation of a Holder or transferee,
     certificate of auditors or any other certificate, statement, instrument,
     opinion, report, notice, request, consent, order, appraisal, bond,
     debenture, note, other evidence of indebtedness or other paper or document
     believed by it to be genuine and to have been signed or presented by the
     proper party or parties;

          (b) if (i) in performing its duties under this Trust Agreement the
     Property Trustee is required to decide between alternative courses of
     action or (ii) in construing any of the provisions of this Trust Agreement
     the Property Trustee finds the same ambiguous or inconsistent with any
     other provisions contained herein or (iii) the Property Trustee is unsure
     of the application of any provision of this Trust Agreement, then, except
     as to any matter as to which the Preferred Securityholders are entitled to
     vote under the terms of this Trust Agreement, the Property Trustee shall
     deliver a notice to the Depositor requesting written instructions of the
     Depositor as to the course of action to be taken and the Property Trustee
     shall take such action, or refrain from taking such action, as the Property
     Trustee shall be instructed in writing to take, or to refrain from taking,
     by the Depositor; provided, however, that if the Property Trustee does not
     receive such instructions of the Depositor within ten Business Days after
     it has delivered such notice, or such reasonably shorter period of time set
     forth in such notice (which to the extent practicable shall not be less
     than two Business Days), it may, but shall be under no duty to, take or
     refrain from taking such action not inconsistent with this Trust Agreement
     as it shall deem advisable and in the best interests of the
     Securityholders, in which event the Property Trustee shall have no
     liability except for its own bad faith, negligence or willful misconduct;

          (c) any direction or act of the Depositor or the Administrative
     Trustees contemplated by this Trust Agreement shall be sufficiently
     evidenced by an Officers' Certificate;

          (d) whenever in the administration of this Trust Agreement, the
     Property Trustee shall deem it desirable that a matter be established
     before undertaking, suffering or omitting any action hereunder, the
     Property Trustee (unless other evidence is herein specifically prescribed)
     may, in the absence of bad faith on its part, request and rely upon an
     Officers' Certificate which, upon receipt of such request, shall be
     promptly delivered by the Depositor or the Administrative Trustees;

          (e) the Property Trustee shall have no duty to see to any recording,
     filing or registration of any instrument (including any financing or
     continuation statement or any filing under tax or securities laws) or any
     rerecording, refiling or reregistration thereof;

          (f) the Property Trustee may consult with counsel (which counsel may
     be counsel to the Depositor or any of its Affiliates, and may include any
     of its employees) and the advice of such counsel shall be full and complete
     authorization and protection in respect of any action taken,

                                       36
<PAGE>
 
     suffered or omitted by it hereunder in good faith and in reliance thereon
     and in accordance with such advice, such counsel may be counsel to the
     Depositor or any of its Affiliates, and may include any of its employees;
     the Property Trustee shall have the right at any time to seek instructions
     concerning the administration of this Trust Agreement from any court of
     competent jurisdiction;

          (g) the Property Trustee shall be under no obligation to exercise any
     of the rights or powers vested in it by this Trust Agreement at the request
     or direction of any of the Securityholders pursuant to this Trust
     Agreement, unless such Securityholders shall have offered to the Property
     Trustee reasonable security or indemnity against the costs, expenses and
     liabilities which might be incurred by it in compliance with such request
     or direction;

          (h) the Property Trustee shall not be bound to make any investigation
     into the facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond, debenture, note or other evidence of indebtedness or other paper or
     document, unless requested in writing to do so by one or more
     Securityholders, but the Property Trustee may make such further inquiry or
     investigation into such facts or matters as it may see fit;

          (i) the Property Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     its agents or attorneys, provided that the Property Trustee shall be
     responsible for its own negligence or recklessness with respect to
     selection of any agent or attorney appointed by it hereunder;

          (j) whenever in the administration of this Trust Agreement the
     Property Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder the Property Trustee (i) may request instructions from the
     Holders of the Trust Securities which instructions may only be given by the
     Holders of the same proportion in Liquidation Amount of the Trust
     Securities as would be entitled to direct the Property Trustee under the
     terms of the Trust Securities in respect of such remedy, right or action,
     (ii) may refrain from enforcing such remedy or right or taking such other
     action until such instructions are received, and (iii) shall be protected
     in acting in accordance with such instructions; and

          (k) except as otherwise expressly provided by this Trust Agreement,
     the Property Trustee shall not be under any obligation to take any action
     that is discretionary under the provisions of this Trust Agreement.

          No provision of this Trust Agreement shall be deemed to impose any
     duty or obligation on the Property Trustee to perform any act or acts or
     exercise any right, power, duty or obligation conferred or imposed on it,
     in any jurisdiction in which it shall be illegal, or in which the Property
     Trustee shall be unqualified or incompetent in accordance with applicable
     law, to perform any such act or acts, or to exercise any such right, power,
     duty or obligation. No permissive power or authority available to the
     Property Trustee shall be construed to be a duty.

          Section 8.4. Not Responsible for Recitals or Issuance of Securities.

          The recitals contained herein and in the Trust Securities Certificates
     shall be taken as the statements of the Trust, and the Trustees do not
     assume any responsibility for their correctness. The Trustees shall not be
     accountable for the use or application by the Depositor of the proceeds of
     the Debentures.

          Section 8.5. May Hold Securities.

          Except as provided in the definition of the term "Outstanding" in
     Article I, any Trustee or any other agent of any Trustee or the Trust, in
     its individual or any other capacity, may become the owner or pledgee of
     Trust Securities and, subject to Sections 8.8 and 8.13, may otherwise deal
     with the Trust with the same rights it would have if it were not a Trustee
     or such other agent.

          Section 8.6. Compensation; Indemnity; Fees.

          The Depositor agrees:

          (a) to pay to the Trustees from time to time reasonable compensation
     for all services rendered by them hereunder (which compensation shall not
     be limited by any provision of law in regard to the compensation of a
     trustee of an express trust);

          (b) except as otherwise expressly provided herein, to reimburse the
     Trustees upon request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustees in accordance with any provision
     of this Trust Agreement (including the reasonable compensation and the
     expenses and disbursements of its agents and counsel), except any such
     expense, disbursement or advance as may be attributable to its negligence
     or bad faith; and

          (c) to the fullest extent permitted by applicable law, to indemnify
     and hold harmless (i) each Trustee, (ii) any Affiliate of any Trustee,
     (iii) any officer, director, shareholder, employee, representative or agent
     of any Trustee, and (iv) any employee or agent of the Trust or its
     Affiliates, (referred to herein as an "Indemnified Person") from and
     against any loss, damage, liability, tax, penalty, expense or claim of any
     kind or nature whatsoever incurred by such Indemnified Person by reason of
     the creation, operation or termination of the Trust or any act or omission
     performed or omitted by such Indemnified Person in good faith on behalf of
     the Trust and in a manner such Indemnified Person reasonably believed to be
     within the scope of authority conferred on such Indemnified Person by this
     Trust Agreement, except that no Indemnified Person shall be entitled to be
     indemnified in respect of any loss, damage or claim incurred by such
     Indemnified Person by reason of negligence or willful misconduct with
     respect to such acts or omissions.

          The provisions of this Section 8.6 shall survive the termination of
     this Trust Agreement.

                                       38
<PAGE>
 
          No Trustee may claim any lien or charge on any Trust Property as a
     result of any amount due pursuant to this Section 8.6.

          The Depositor and any Trustee may engage in or possess an interest in
     other business ventures of any nature or description, independently or with
     others, similar or dissimilar to the business of the Trust, and the Trust
     and the Holders of Trust Securities shall have no rights by virtue of this
     Trust Agreement in and to such independent ventures or the income or
     profits derived therefrom, and the pursuit of any such venture, even if
     competitive with the business of the Trust, shall not be deemed wrongful or
     improper. Neither the Depositor, nor any Trustee, shall be obligated to
     present any particular investment or other opportunity to the Trust even if
     such opportunity is of a character that, if presented to the Trust, could
     be taken by the Trust, and the Depositor or any Trustee shall have the
     right to take for its own account (individually or as a partner or
     fiduciary) or to recommend to others any such particular investment or
     other opportunity. Any Trustee may engage or be interested in any financial
     or other transaction with the Depositor or any Affiliate of the Depositor,
     or may act as depository for, trustee or agent for, or act on any committee
     or body of holders of, securities or other obligations of the Depositor or
     its Affiliates.

          Section 8.7. Corporate Property Trustee Required; Eligibility of
     Trustees.

          (a) There shall at all times be a Property Trustee hereunder with
     respect to the Trust Securities. The Property Trustee shall be a Person
     that is eligible pursuant to the Trust Indenture Act to act as such and has
     a combined capital and surplus of at least $50,000,000. If any such Person
     publishes reports of condition at least annually, pursuant to law or to the
     requirements of its supervising or examining authority, then for the
     purposes of this Section, the combined capital and surplus of such Person
     shall be deemed to be its combined capital and surplus as set forth in its
     most recent report of condition so published. If at any time the Property
     Trustee with respect to the Trust Securities shall cease to be eligible in
     accordance with the provisions of this Section, it shall resign immediately
     in the manner and with the effect hereinafter specified in this Article.

          (b) There shall at all times be one or more Administrative Trustees
     hereunder with respect to the Trust Securities. Each Administrative Trustee
     shall be either a natural person who is at least 21 years of age or a legal
     entity that shall act through one or more persons authorized to bind that
     entity.

          (c) There shall at all times be a Delaware Trustee with respect to the
     Trust Securities. The Delaware Trustee shall either be (i) a natural person
     who is at least 21 years of age and a resident of the State of Delaware or
     (ii) a legal entity with its principal place of business in the State of
     Delaware and that otherwise meets the requirements of applicable Delaware
     law that shall act through one or more persons authorized to bind such
     entity.

          Section 8.8. Conflicting Interests.

                                       39
<PAGE>
 
          If the Property Trustee has or shall acquire a conflicting interest
     within the meaning of the Trust Indenture Act, the Property Trustee shall
     either eliminate such interest or resign, to the extent and in the manner
     provided by, and subject to the provisions of, the Trust Indenture Act and
     this Trust Agreement.

          Section 8.9. Co-Trustees and Separate Trustee.

          Unless an Event of Default shall have occurred and be continuing, at
     any time or times, for the purpose of meeting the legal requirements of the
     Trust Indenture Act or of any jurisdiction in which any part of the Trust
     Property may at the time be located, the Depositor and the Administrative
     Trustees, by agreed action of the majority of such Trustees, shall have
     power to appoint, and upon the written request of the Administrative
     Trustees, the Depositor shall for such purpose join with the Administrative
     Trustees in the execution, delivery, and performance of all instruments and
     agreements necessary or proper to appoint, one or more Persons approved by
     the Property Trustee either to act as co-trustee, jointly with the Property
     Trustee, of all or any part of such Trust Property, or to the extent
     required by law to act as separate trustee of any such property, in either
     case with such powers as may be provided in the instrument of appointment,
     and to vest in such Person or Persons in the capacity aforesaid, any
     property, title, right or power deemed necessary or desirable, subject to
     the other provisions of this Section. If the Depositor does not join in
     such appointment within 15 days after the receipt by it of a request so to
     do, or in case a Debenture Event of Default has occurred and is continuing,
     the Property Trustee alone shall have power to make such appointment. Any
     co-trustee or separate trustee appointed pursuant to this Section shall
     either be (i) a natural person who is at least 21 years of age and a
     resident of the United States or (ii) a legal entity with its principal
     place of business in the United States that shall act through one or more
     persons authorized to bind such entity.

          Should any written instrument from the Depositor be required by any
     co-trustee or separate trustee so appointed for more fully confirming to
     such co-trustee or separate trustee such property, title, right, or power,
     any and all such instruments shall, on request, be executed, acknowledged
     and delivered by the Depositor.

          Every co-trustee or separate trustee shall, to the extent permitted by
     law, but to such extent only, be appointed subject to the following terms,
     namely:

          (a) The Trust Securities shall be executed and delivered and all
     rights, powers, duties, and obligations hereunder in respect of the custody
     of securities, cash and other personal property held by, or required to be
     deposited or pledged with, the Trustees specified hereunder shall be
     exercised solely by such Trustees and not by such co-trustee or separate
     trustee.

          (b) The rights, powers, duties, and obligations hereby conferred or
     imposed upon the Property Trustee in respect of any property covered by
     such appointment shall be conferred or imposed upon and exercised or
     performed by the Property Trustee or by the Property Trustee and such co-
     trustee or separate trustee jointly, as shall be provided in the instrument
     appointing such co-trustee or separate trustee, except to the extent that
     under any law of any jurisdiction

                                       40
<PAGE>
 
     in which any particular act is to be performed, the Property Trustee shall
     be incompetent or unqualified to perform such act, in which event such
     rights, powers, duties and obligations shall be exercised and performed by
     such co-trustee or separate trustee.

          (c) The Property Trustee at any time, by an instrument in writing
     executed by it, with the written concurrence of the Depositor, may accept
     the resignation of or remove any co-trustee or separate trustee appointed
     under this Section, and, in case a Debenture Event of Default has occurred
     and is continuing, the Property Trustee shall have power to accept the
     resignation of, or remove, any such co-trustee or separate trustee without
     the concurrence of the Depositor. Upon the written request of the Property
     Trustee, the Depositor shall join with the Property Trustee in the
     execution, delivery and performance of all instruments and agreements
     necessary or proper to effectuate such resignation or removal. A successor
     to any co-trustee or separate trustee so resigned or removed may be
     appointed in the manner provided in this Section.

          (d) No co-trustee or separate trustee hereunder shall be personally
     liable by reason of any act or omission of the Property Trustee or any
     other trustee hereunder.

          (e) The Property Trustee shall not be liable by reason of any act of a
     co-trustee or separate trustee.

          (f) Any Act of Holders delivered to the Property Trustee shall be
     deemed to have been delivered to each such co-trustee and separate trustee.

          Section 8.10. Resignation and Removal; Appointment of Successor.

          No resignation or removal of any Trustee (the "Relevant Trustee") and
     no appointment of a successor Trustee pursuant to this Article shall become
     effective until the acceptance of appointment by the successor Trustee in
     accordance with the applicable requirements of Section 8.11.

          Subject to the immediately preceding paragraph, the Relevant Trustee
     may resign at any time by giving written notice thereof to the
     Securityholders. If the instrument of acceptance by the successor Trustee
     required by Section 8.11 shall not have been delivered to the Relevant
     Trustee within 30 days after the giving of such notice of resignation, the
     Relevant Trustee may petition, at the expense of the Trust, any court of
     competent jurisdiction for the appointment of a successor Relevant Trustee.

          Unless a Debenture Event of Default shall have occurred and be
     continuing, any Trustee may be removed at any time by Act of the Common
     Securityholder. If a Debenture Event of Default shall have occurred and be
     continuing, the Property Trustee or the Delaware Trustee, or both of them,
     may be removed at such time by Act of the Holders of a majority in
     Liquidation Amount of the Preferred Securities, delivered to the Relevant
     Trustee (in its individual capacity and on behalf of the Trust). An
     Administrative Trustee may be removed by the Common Securityholder at any
     time.

                                       41
<PAGE>
 
          If any Trustee shall resign, be removed or become incapable of acting
     as Trustee, or if a vacancy shall occur in the office of any Trustee for
     any cause, at a time when no Debenture Event of Default shall have occurred
     and be continuing, the Common Securityholder, by Act of the Common
     Securityholder delivered to the retiring Trustee, shall promptly appoint a
     successor Trustee or Trustees, and the retiring Trustee shall comply with
     the applicable requirements of Section 8.11. If the Property Trustee or the
     Delaware Trustee shall resign, be removed or become incapable of continuing
     to act as the Property Trustee or the Delaware Trustee, as the case may be,
     at a time when a Debenture Event of Default shall have occurred and be
     continuing, the Preferred Securityholders, by Act of the Securityholders of
     a majority in Liquidation Amount of the Preferred Securities then
     Outstanding delivered to the retiring Relevant Trustee, shall promptly
     appoint a successor Relevant Trustee or Trustees, and such successor
     Trustee shall comply with the applicable requirements of Section 8.11. If
     an Administrative Trustee shall resign, be removed or become incapable of
     acting as Administrative Trustee, at a time when a Debenture Event of
     Default shall have occurred and be continuing, the Common Securityholder by
     Act of the Common Securityholder delivered to the Administrative Trustee
     shall promptly appoint a successor Administrative Trustee or Administrative
     Trustees and such successor Administrative Trustee or Trustees shall comply
     with the applicable requirements of Section 8.11. If no successor Relevant
     Trustee shall have been so appointed by the Common Securityholder or the
     Preferred Securityholders and accepted appointment in the manner required
     by Section 8.11, any Securityholder who has been a Securityholder of Trust
     Securities for at least six months may, on behalf of himself and all others
     similarly situated, petition any court of competent jurisdiction for the
     appointment of a successor Relevant Trustee.

          The Property Trustee shall give notice of each resignation and each
     removal of a Trustee and each appointment of a successor Trustee to all
     Securityholders in the manner provided in Section 10.8 and shall give
     notice to the Depositor. Each notice shall include the name of the
     successor Relevant Trustee and the address of its Corporate Trust Office if
     it is the Property Trustee.

          Notwithstanding the foregoing or any other provision of this Trust
     Agreement, in the event any Administrative Trustee or a Delaware Trustee
     who is a natural person dies or becomes, in the opinion of the Depositor,
     incompetent or incapacitated, the vacancy created by such death,
     incompetence or incapacity may be filled by (a) the unanimous act of the
     remaining Administrative Trustees if there are at least two of them or (b)
     otherwise by the Depositor (with the successor in each case being a Person
     who satisfies the eligibility requirement for Administrative Trustees or
     Delaware Trustee, as the case may be, set forth in Section 8.7).

          Section 8.11. Acceptance of Appointment by Successor.

          In case of the appointment hereunder of a successor Trustee such
     successor Trustee so appointed shall execute, acknowledge and deliver to
     the Trust and to the retiring Trustee an instrument accepting such
     appointment, and thereupon the resignation or removal of the retiring
     Trustee shall become effective and such successor Trustee, without any
     further act, deed or conveyance, shall become vested with all the rights,
     powers, trusts and duties of the retiring

                                       42
<PAGE>
 
     Trustee; but, on the request of the Depositor or the successor Trustee,
     such retiring Trustee shall, upon payment of its charges, execute and
     deliver an instrument transferring to such successor Trustee all the
     rights, powers and trusts of the retiring Trustee and if the Property
     Trustee is the resigning Trustee shall duly assign, transfer and deliver to
     the successor Trustee all property and money held by such retiring Property
     Trustee hereunder.

          In case of the appointment hereunder of a successor Relevant Trustee,
     the retiring Relevant Trustee and each successor Relevant Trustee with
     respect to the Trust Securities shall execute and deliver an amendment
     hereto wherein each successor Relevant Trustee shall accept such
     appointment and which (a) shall contain such provisions as shall be
     necessary or desirable to transfer and confirm to, and to vest in, each
     successor Relevant Trustee all the rights, powers, trusts and duties of the
     retiring Relevant Trustee with respect to the Trust Securities and the
     Trust and (b) shall add to or change any of the provisions of this Trust
     Agreement as shall be necessary to provide for or facilitate the
     administration of the Trust by more than one Relevant Trustee, it being
     understood that nothing herein or in such amendment shall constitute such
     Relevant Trustees co-trustees and upon the execution and delivery of such
     amendment the resignation or removal of the retiring Relevant Trustee shall
     become effective to the extent provided therein and each such successor
     Relevant Trustee, without any further act, deed or conveyance, shall become
     vested with all the rights, powers, trusts and duties of the retiring
     Relevant Trustee; but, on request of the Trust or any successor Relevant
     Trustee such retiring Relevant Trustee shall duly assign, transfer and
     deliver to such successor Relevant Trustee all Trust Property, all proceeds
     thereof and money held by such retiring Relevant Trustee hereunder with
     respect to the Trust Securities and the Trust.

          Upon request of any such successor Relevant Trustee, the Trust shall
     execute any and all instruments for more fully and certainly vesting in and
     confirming to such successor Relevant Trustee all such rights, powers and
     trusts referred to in the first or second preceding paragraph, as the case
     may be.

          No successor Relevant Trustee shall accept its appointment unless at
     the time of such acceptance such successor Relevant Trustee shall be
     qualified and eligible under this Article.

          Section 8.12. Merger, Conversion, Consolidation or Succession to
     Business.

          Any corporation into which the Property Trustee or the Delaware
     Trustee may be merged or converted or with which it may be consolidated, or
     any corporation resulting from any merger, conversion or consolidation to
     which such Relevant Trustee shall be a party, or any corporation succeeding
     to all or substantially all the corporate trust business of such Relevant
     Trustee, shall be the successor of such Relevant Trustee hereunder,
     provided such corporation shall be otherwise qualified and eligible under

     act on the part of any of the parties hereto.

     Trust.

          In case of the pendency of any receivership, insolvency, liquidation,
     bankruptcy, reorganization, arrangement, adjustment, composition or other
     similar judicial proceeding relative to the Trust or any other obligor upon
     the Trust Securities or the property of the Trust or of such other obligor
     or their creditors, the Property Trustee (irrespective of whether any
     Distributions on the Trust Securities shall then be due and payable as
     therein expressed or by declaration or otherwise and irrespective of
     whether the Property Trustee shall have made any demand on the Trust for
     the payment of any past due Distributions) shall be entitled and empowered,
     to the fullest extent permitted by law, by intervention in such proceeding
     or otherwise:

          (a) to file and prove a claim for the whole amount of any
     Distributions owing and unpaid in respect of the Trust Securities and to
     file such other papers or documents as may be necessary or advisable in
     order to have the claims of the Property Trustee (including any claim for
     the reasonable compensation, expenses, disbursements and advances of the
     Property Trustee, its agents and counsel) and of the Holders allowed in

     similar official in any such judicial proceeding is hereby authorized by
     each Holder to make such payments to the Property Trustee and, in the event
     the Property Trustee shall consent to the making of such payments directly
     to the Holders, to pay to the Property Trustee any amount due it for the
     reasonable compensation, expenses, disbursements and advances of the
     Property Trustee, its agents and counsel, and any other amounts due the
     Property Trustee.

          Nothing herein contained shall be deemed to authorize the Property
     Trustee to authorize or consent to or accept or adopt on behalf of any
     Holder any plan of reorganization, arrangement adjustment or compensation
     affecting the Trust Securities or the rights of any Holder thereof or to
     authorize the Property Trustee to vote in respect of the claim of any
     Holder in any such proceeding.

          Section 8.14. Reports by Property Trustee.

          (a) Not later than ________ __ of each year commencing with ________

     written statement to such effect;

                                       44

     in any material respect with such obligations, a description of such
     noncompliance; and

          (iii) any change in the property and funds in its possession as
     Property Trustee since the date of its last report and any action taken by
     the Property Trustee in the performance of its duties hereunder which it
     has not previously reported and which in its opinion materially affects the
     Trust Securities.

     (b) In addition the Property Trustee shall transmit to Securityholders such
reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times

     Section 8.17. Number of Trustees.

     (a) The number of Trustees shall be four, provided that the Holder of all

number of Administrative Trustees. The Property Trustee and the Delaware Trustee

     (b) If a Trustee ceases to hold office for any reason and the number of
Administrative Trustees is not reduced pursuant to Section 8.17(a), or if the

                                       45
<PAGE>

with a Trustee appointed in accordance with Section 8.10.

     (c) The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of a Trustee shall not operate to annul the
Trust. Whenever a vacancy in the number of Administrative Trustees shall occur,

accordance with Section 8.10, the Administrative Trustees in office, regardless
of their number (and notwithstanding any other provision of this Agreement),

                                  ARTICLE IX.

                      Termination, Liquidation and Merger

     Section 9.1. Termination Upon Expiration Date.

     Unless earlier terminated, the Trust shall automatically terminate on
December 31, 2045 (the "Expiration Date"), following the distribution of the
Trust Property in accordance with Section 9.4.

     Section 9.2. Early Termination.

     The first to occur of any of the following events is an "Early Termination
Event":

     (a) the occurrence of a Bankruptcy Event in respect of, or the dissolution
or liquidation of, the Holder of the Common Securities;

                                       46
<PAGE>
 
     (b) the written direction to the Property Trustee from the Depositor at any
time to terminate the Trust and distribute Debentures to Securityholders in
exchange for the Preferred Securities (which direction is optional and wholly
within the discretion of the Depositor);

     (c) the redemption of all of the Preferred Securities in connection with
the redemption of all the Debentures; and

     (d) the entry of an order for dissolution of the Trust by a court of
competent jurisdiction.

     Section 9.3. Termination.

     The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 9.4, or upon the
redemption of all of the Trust Securities pursuant to Section 4.2, of all
amounts required to be distributed hereunder upon the final payment of the Trust
Securities; (b) the payment of any expenses owed by the Trust; and (c) the
discharge of all administrative duties of the Administrative Trustees, including
the performance of any tax reporting obligations with respect to the Trust or
the Securityholders.

     Section 9.4. Liquidation.

     (a) If an Early Termination Event specified in clause (a), (b) or (d) of
Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated by
the Trustees as expeditiously as the Trustees determine to be possible by
distributing, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, to each Securityholder a Like Amount of Debentures,
subject to Section 9.4(d). Notice of liquidation shall be given by the Property
Trustee by first-class mail, postage prepaid mailed not later than 30 nor more
than 60 days prior to the Liquidation Date to each Holder of Trust Securities at
such Holder's address appearing in the Securities Register. All notices of
liquidation shall:

          (i) state the Liquidation Date;

          (ii) state that from and after the Liquidation Date, the Trust
     Securities will no longer be deemed to be Outstanding and any Trust
     Securities Certificates not surrendered for exchange will be deemed to
     represent a Like Amount of Debentures; and

          (iii) provide such information with respect to the mechanics by which
     Holders may exchange Trust Securities Certificates for Debentures, or if
     Section 9.4(d) applies receive a Liquidation Distribution, as the
     Administrative Trustees or the Property Trustee shall deem appropriate.

     (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Securityholders,
the Property Trustee shall establish a record date for such distribution (which
shall be not more than 45 days prior to the Liquidation

                                       47
<PAGE>
 
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

     (c) Except where Section 9.2(c) or 9.4(d) applies, after the Liquidation
Date, (i) the Trust Securities will no longer be deemed to be Outstanding, (ii)
certificates representing a Like Amount of Debentures will be issued to holders
of Trust Securities Certificates, upon surrender of such certificates to the
Administrative Trustees or their agent for exchange, (iii) the Depositor shall
use its best efforts to have the Debentures listed on the New York Stock
Exchange or on such other exchange, interdealer quotation system or self-
regulatory organization as the Preferred Securities are then listed, (iv) any
Trust Securities Certificates not so surrendered for exchange will be deemed to
represent a Like Amount of Debentures, accruing interest at the rate provided
for in the Debentures from the last Distribution Date on which a Distribution
was made on such Trust Securities Certificates until such certificates are so
surrendered (and until such certificates are so surrendered, no payments of
interest or principal will be made to Holders of Trust Securities Certificates
with respect to such Debentures) and (v) all rights of Securityholders holding
Trust Securities will cease, except the right of such Securityholders to receive
Debentures upon surrender of Trust Securities Certificates.

     (d) In the event that, notwithstanding the other provisions of this Section
9.4, whether because of an order for dissolution entered by a court of competent
jurisdiction or otherwise, distribution of the Debentures in the manner provided
herein is determined by the Property Trustee not to be practical, the Trust
Property shall be liquidated, and the Trust shall be dissolved, wound-up or
terminated, by the Property Trustee in such manner as the Property Trustee
determines. In such event, on the date of the dissolution, winding-up or other
termination of the Trust, Securityholders will be entitled to receive out of the
assets of the Trust available for distribution to Securityholders, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, an amount equal to the Liquidation Amount per Trust Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"). If, upon any such dissolution, winding up
or termination, the Liquidation Distribution can be paid only in part because
the Trust has insufficient assets available to pay in full the aggregate
Liquidation Distribution, then, subject to the next succeeding sentence, the
amounts payable by the Trust on the Trust Securities shall be paid on a pro rata
basis (based upon Liquidation Amounts). The holder of the Common Securities will
be entitled to receive Liquidation Distributions upon any such dissolution,
winding-up or termination pro rata (determined as aforesaid) with Holders of
Preferred Securities, except that, if a Debenture Event of Default has occurred
and is continuing, the Preferred Securities shall have a priority over the
Common Securities.

     Section 9.5. Mergers, Consolidations, Amalgamations or Replacements of the
Trust.

     The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 9.5. At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the Holders of the Preferred

                                       48
<PAGE>
 
Securities, the Property Trustee or the Delaware Trustee, the Trust may merge
with or into, consolidate, amalgamate, or be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any State; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities") so long as the Successor Securities rank
the same as the Preferred Securities rank in priority with respect to
distributions and payments upon liquidation, redemption and otherwise, (ii) the
Depositor expressly appoints a trustee of such successor entity possessing the
same powers and duties as the Property Trustee as the holder of the Debentures,
(iii) the Successor Securities are listed or traded, or any Successor Securities
will be listed upon notification of issuance, on any national securities
exchange or other organization on which the Preferred Securities are then listed
or traded, if any, (iv) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not cause the Preferred Securities (including
any Successor Securities) to be downgraded by any nationally recognized
statistical rating organization, (v) such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Preferred Securities (including
any Successor Securities) in any material respect, (vi) such successor entity
has a purpose identical to that of the Trust, (vii) prior to such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, the
Depositor has received an Opinion of Counsel to the effect that (a) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Preferred Securities (including any Successor Securities) in any material
respect, and (b) following such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, neither the Trust nor such successor
entity will be required to register as an investment company under the 1940 Act
and (viii) the Depositor owns all of the Common Securities of such successor
entity and guarantees the obligations of such successor entity under the
Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100% in Liquidation Amount of the Preferred Securities, consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties and assets substantially as an entirety to any other entity or
permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger, replacement, conveyance,
transfer or lease would cause the Trust or the successor entity to be classified
as an association taxable as a corporation or as other than a grantor trust for
United States Federal income tax purposes.


                                   ARTICLE X.

                            Miscellaneous Provisions

     Section 10.1. Limitation of Rights of Securityholders.

     The death or incapacity of any person having an interest, beneficial or
otherwise, in Trust Securities shall not operate to terminate this Trust
Agreement, nor entitle the legal

<PAGE>
 
representatives or heirs of such person or any Securityholder for such person,
to claim an accounting, take any action or bring any proceeding in any court for
a partition or winding up of the arrangements contemplated hereby, nor otherwise
affect the rights, obligations and liabilities of the parties hereto or any of
them.

     Section 10.2. Amendment.

     (a) This Trust Agreement may be amended from time to time by the Property
Trustee, the Administrative Trustees and the Depositor, without the consent of
any Securityholders, (i) to cure any ambiguity, correct or supplement any
provision herein which may be inconsistent with any other provision herein, or
to make any other provisions with respect to matters or questions arising under
this Trust Agreement, which shall not be inconsistent with the other provisions
of this Trust Agreement, or (ii) to modify, eliminate or add to any provisions
of this Trust Agreement to such extent as shall be necessary to ensure that the
Trust will not be classified for United States Federal income tax purposes as an
association taxable as a corporation or as other than a grantor trust at all
times that any Trust Securities are outstanding or to ensure that the Trust will
not be required to register as an investment company under the 1940 Act;
provided, however, that in the case of clause (i), such action shall not
adversely affect in any material respect the interests of any Securityholder,
and any amendments of this Trust Agreement shall become effective when notice
thereof is given to the Securityholders.

     (b) Except as provided in Section 10.2(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust or
cause the Trust to be an association taxable as a corporation for United States
Federal income tax purposes or the Trust's exemption from status of an
investment company under the 1940 Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder (such consent
being obtained in accordance with Section 6.3 or 6.6 hereof), this Trust

Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
paragraph (c) of this Section 10.2 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an investment company under the 1940 Act or cause the Trust to be
classified as an association taxable as a corporation or not to be a grantor
trust for United States Federal income tax purposes.

<PAGE>
 
     (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor, this Trust Agreement may not be amended in
a manner which imposes any additional obligation on the Depositor.

     (f) In the event that any amendment to this Trust Agreement is made, the
Administrative Trustees shall promptly provide to the Depositor a copy of such
amendment.

Trust Agreement.

The Depository Trust Company,
55 Water Street, 49th Floor,

Attention: _______________
     General Counsel's Office

Re:   Mellon Capital I ____% Cumulative Trust Preferred Securities, Series A

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the Mellon
Capital I ____% Cumulative Trust Preferred Securities, Series A (the "Preferred
Securities"), of Mellon Capital I, a Delaware business trust (the "Issuer"),
formed pursuant to a Trust Agreement between Mellon Bank Corporation (the
"Corporation") and The Chase Manhattan Bank, as Property Trustee, Chase
Manhattan Bank Delaware, as Delaware Trustee, and the Administrative Trustees
named therein. The payment of distributions on the Preferred Securities, and
payments due upon liquidation of Issuer or redemption of the Preferred
Securities, to the extent the Issuer has funds available for the payment thereof
are guaranteed by the Corporation to the extent set forth in a Guarantee
Agreement, dated December __, 1996, by the Corporation with respect to the
Preferred Securities. The Corporation and the Issuer propose to sell the
Preferred Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement, dated December __, 1996, by and among the Underwriters,
the Issuer and the Corporation, and the Underwriters wish to take delivery of
the Preferred Securities through DTC. The Chase Manhattan Bank is acting as
transfer agent and registrar with respect to the Preferred Securities (the
"Transfer Agent and Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:

     1. Prior to the closing of the sale of the Preferred Securities to the
Underwriters, which is expected to occur on or about December __, 1996, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") registered in the name of DTC's
Preferred Securities nominee, Cede & Co., representing an aggregate of
____________ Preferred Securities and bearing the following legend:

          Unless this certificate is presented by an authorized representative
          of The Depository Trust Company, a New York corporation ("DTC"), to
          Issuer or its

                                       56
<PAGE>
 
          agent for registration of transfer, exchange, or payment, and any
          certificate issued is registered in the name of Cede & Co. or in such
          other name as is requested by an authorized representative of DTC (and
          any payment is made to Cede & Co. or to such other entity as is
          requested by an authorized representative of DTC), ANY TRANSFER,
          PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
          IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has
          an interest herein.

     2. The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances. The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

     3. In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4. In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.

notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC
not less than 30 calendar days prior to such event by a secure means in the
manner set forth in paragraph 4. Such redemption notice shall be sent to DTC's
Call Notification Department at (516) 227-4164 or (516) 227-4190, and receipt of

     6. In the event of any invitation to tender the Preferred Securities,
notice specifying the terms of the tender and the Publication Date of such
notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC by
a secure means and in a timely manner as described in paragraph 4. Notices to
DTC pursuant to this paragraph and notices of other corporate actions (including
mandatory tenders, exchanges and capital changes) shall be sent, unless
notification to another department is expressly provided for herein, by telecopy
to DTC's Reorganization Department at (212) 709-1093 or (212) 709-1094 and
receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by

          The Depository Trust Company
          7 Hanover Square, 23rd Floor
          New York, New York 10004-2695

     7. All notices and payment advices sent to DTC shall contain the CUSIP
number or numbers of the Preferred Securities and the accompanying designation
of the Preferred Securities, which, as of the date of this letter, is "Mellon
Capital I ____% Cumulative Trust Preferred Securities, Series A."

                                       58
<PAGE>
 
     8. Distribution payments or other cash payments with respect to the
Preferred Securities evidenced by the Global Certificate shall be received by
Cede & Co., as nominee of DTC, or its registered assigns in next day funds on
each payment date (or in accordance with existing arrangements between the
Issuer or the Transfer Agent and Registrar and DTC). Such payments shall be made
payable to the order of Cede & Co., and shall be addressed as follows:

          NDFS Redemption Department
          The Depository Trust Company
          7 Hanover Square, 23rd Floor
          New York, New York 10004-2695

     9. DTC may by prior written notice direct the Issuer and the Transfer Agent
and Registrar to use any other telecopy number or address of DTC as the number
or address to which notices or payments may be sent.

     10. In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Preferred Securities outstanding evidenced by Global
Certificates, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

     11. DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law. Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar, and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any
other documents of transfer reasonably requested by the Issuer or the Transfer
Agent and Registrar.

     12. In the event that the Issuer determines that beneficial owners of
Preferred Securities shall be able to obtain definitive Preferred Securities,
the Issuer or the Transfer Agent and Registrar shall notify DTC of the
availability of certificates. In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     13. This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

     Nothing herein shall be deemed to require the Transfer Agent and Registrar
to advance funds on behalf of Mellon Capital I.

                         Very truly yours,

                    AGREEMENT AS TO EXPENSES AND LIABILITIES

          Agreement, dated as of December __, 1996, between Mellon Bank

                                   ARTICLE I

          Section 1.1.   Guarantee by the Corporation.

          Subject to the terms and conditions hereof, the Corporation hereby
irrevocably and unconditionally guarantees to each person or entity to whom the
Trust is now or hereafter becomes indebted or liable (the "Beneficiaries") the
full payment, when and as due, of any and all Obligations (as hereinafter
defined) to such Beneficiaries. As used herein, "Obligations" means any costs,
expenses or liabilities of the Trust, other than obligations of the Trust to pay
to holders of any Preferred Securities or other similar interests in the Trust
the amounts due such holders pursuant to the terms of the Preferred Securities
or such other similar interests, as the case may be. This Agreement is intended
to be for the benefit of, and to be enforceable by, all such Beneficiaries,
whether or not such Beneficiaries have received notice hereof.

          Section 1.2.   Term of Agreement.

are no Beneficiaries remaining; provided, however, that this Agreement shall
continue to be effective or shall be reinstated, as the case may be, if at any

<PAGE>
 
of Preferred Securities or any Beneficiary must restore payment of any sums paid

as guarantee trustee or under this Agreement for any reason whatsoever. This
Agreement is continuing, irrevocable, unconditional and absolute.

          Section 1.3.   Waiver of Notice.

          The Corporation hereby waives notice of acceptance of this Agreement
and of any Obligation to which it applies or may apply, and the Corporation

notice of dishonor, notice of redemption and all other notices and demands.

          Section 1.4.   No Impairment.

happening from time to time of any of the following:

          (a) the extension of time for the payment by the Trust of all or any
portion of the Obligations or for the performance of any other obligation under,
arising out of, or in connection with, the obligations;

          (b) any failure, omission, delay or lack of diligence on the part of
the Beneficiaries to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Beneficiaries with respect to the Obligations or any

          (c) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Trust or any of the assets of the
Trust.

There shall be no obligation of the Beneficiaries to give notice to, or obtain
the consent of, the Corporation with respect to the happening of any of the
foregoing.

          Section 1.5.   Enforcement.

          A Beneficiary may enforce this Agreement directly against the
Corporation and the Corporation waives any right or remedy to require that any
action be brought against the Trust or any other person or entity before
proceeding against the Corporation.

          Section 1.6.   Subrogation.

                                       64
<PAGE>
 
          The Corporation shall be subrogated to all (if any) rights of the
Trust in respect of any amounts paid to the Beneficiaries by the Corporation
under this Agreement; provided, however, that the Corporation shall not (except
to the extent required by mandatory provisions of law) be entitled to enforce or
exercise any rights which it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under this
Agreement, if, at the time of any such payment, any amounts are due and unpaid

<PAGE>
 
  Section 3.1.   Powers and Duties of the Guarantee Trustee.

  (a) This Guarantee Agreement shall be held by the Guarantee Trustee for the
benefit of the Holders, and the Guarantee Trustee shall not transfer this
Guarantee Agreement to any Person except a Holder exercising his or her rights
pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on acceptance by
such Successor Guarantee Trustee of its appointment to act as Successor
Guarantee Trustee. The right, title and interest of the Guarantee Trustee shall
automatically vest in any Successor Guarantee Trustee, upon acceptance by such
Successor Guarantee Trustee of its appointment hereunder, and such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered pursuant to the appointment of such Successor
Guarantee Trustee.

  (b) If an Event of Default has occurred and is continuing, the Guarantee
Trustee shall enforce this Guarantee Agreement for the benefit of the Holders.

  (c) The Guarantee Trustee, before the occurrence of any Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Guarantee Agreement, and no implied covenants shall be read into this Guarantee
Agreement against the Guarantee Trustee. In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

  (d) No provision of this Guarantee Agreement shall be construed to relieve the
Guarantee Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that:

     (i) prior to the occurrence of any Event of Default and after the curing or
  waiving of all such Events of Default that may have occurred:

        (A) the duties and obligations of the Guarantee Trustee shall be
     determined solely by the express provisions of this Guarantee Agreement,
     and the Guarantee Trustee shall not be liable except for the performance of
     such duties and obligations as are specifically set forth in this Guarantee
     Agreement; and

        (B) in the absence of bad faith on the part of the Guarantee Trustee,
     the Guarantee Trustee may conclusively rely, as to the truth of the
     statements and the correctness of the opinions expressed therein, upon any
     certificates or opinions furnished to the Guarantee Trustee and conforming
     to the requirements of this Guarantee Agreement; but in the case of any
     such certificates or opinions that by any provision hereof or of the Trust
     Indenture Act are specifically required to be furnished to the Guarantee
     Trustee, the Guarantee Trustee shall be under a duty to examine the same to
     determine whether or not they conform to the requirements of this Guarantee
     Agreement;

     (ii) the Guarantee Trustee shall not be liable for any error of judgment
  made in good faith by a Responsible Officer of the Guarantee Trustee, unless
  it shall be proved that the Guarantee Trustee was negligent in ascertaining
  the pertinent facts upon which such judgment was made;

     (iii) the Guarantee Trustee shall not be liable with respect to any action
  taken or omitted to be taken by it in good faith in accordance with the
  direction of the Holders of not less than a Majority in liquidation preference
  of the Preferred Securities relating to the time, method and place of
  conducting any proceeding for any remedy available to the Guarantee Trustee,
  or exercising any trust or power conferred upon the Guarantee Trustee under
  this Guarantee Agreement; and

                                       5
<PAGE>
 
  (iv) no provision of this Guarantee Agreement shall require the Guarantee
  Trustee to expend or risk its own funds or otherwise incur personal financial
  liability in the performance of any of its duties or in the exercise of any of
  its rights or powers, if the Guarantee Trustee shall have reasonable grounds
  for believing that the repayment of such funds or liability is not reasonably
  assured to it under the terms of this Guarantee Agreement or adequate
  indemnity against such risk or liability is not reasonably assured to it.

  Section 3.2.   Certain Rights of Guarantee Trustee.

  (a) Subject to the provisions of Section 3.1:

     (i) The Guarantee Trustee may rely and shall be fully protected in acting
  or refraining from acting upon any resolution, certificate, statement,
  instrument, opinion, report, notice, request, direction, consent, order, bond,
  debenture, note, other evidence of indebtedness or other paper or document
  reasonably believed by it to be genuine and to have been signed, sent or
  presented by the proper party or parties.

     (ii) Any direction or act of the Guarantor contemplated by this Guarantee
  Agreement shall be sufficiently evidenced by an Officers' Certificate unless
  otherwise prescribed herein.

     (iii) Whenever, in the administration of this Guarantee Agreement, the
  Guarantee Trustee shall deem it desirable that a matter be proved or
  established before taking, suffering or omitting to take any action hereunder,
  the Guarantee Trustee (unless other evidence is herein specifically
  prescribed) may, in the absence of bad faith on its part, request and rely
  upon an Officers' Certificate which, upon receipt of such request from the
  Guarantee Trustee, shall be promptly delivered by the Guarantor.

     (iv) The Guarantee Trustee may consult with legal counsel, and the written
  advice or opinion of such legal counsel with respect to legal matters shall be
  full and complete authorization and protection in respect of any action taken,
  suffered or omitted to be taken by it hereunder in good faith and in
  accordance with such advice or opinion. Such legal counsel may be legal
  counsel to the Guarantor or any of its Affiliates and may be one of its
  employees. The Guarantee Trustee shall have the right at any time to seek
  instructions concerning the administration of this Guarantee Agreement from
  any court of competent jurisdiction.

     (v) The Guarantee Trustee shall be under no obligation to exercise any of
  the rights or powers vested in it by this Guarantee Agreement at the request
  or direction of any Holder, unless such Holder shall have provided to the
  Guarantee Trustee such adequate security and indemnity as would satisfy a
  reasonable person in the position of the Guarantee Trustee, against the costs,
  expenses (including attorneys' fees and expenses) and liabilities that might
  be incurred by it in complying with such request or direction, including such
  reasonable advances as may be requested by the Guarantee Trustee; provided
  that, nothing contained in this Section 3.2(a)(v) shall be taken to relieve
  the Guarantee Trustee, upon the occurrence of an Event of Default, of its
  obligation to exercise the rights and powers vested in it by this Guarantee
  Agreement.

     (vi) The Guarantee Trustee shall not be bound to make any investigation
  into the facts or matters stated in any resolution, certificate, statement,
  instrument, opinion, report, notice, request, direction, consent, order, bond,
  debenture, note, other evidence of indebtedness or other paper or document,
  but the Guarantee Trustee, in its discretion, may make such further inquiry or
  investigation into such facts or matters as it may see fit.

     (vii) The Guarantee Trustee may execute any of the trusts or powers
  hereunder or perform any duties hereunder either directly or by or through its
  agents or attorneys, and the Guarantee Trustee shall not be responsible for
  any misconduct or negligence on the part of any such agent or attorney
  appointed with due care by it hereunder.

                                       6
<PAGE>
 
  (viii) Whenever in the administration of this Guarantee Agreement the
  Guarantee Trustee shall deem it desirable to receive instructions with respect
  to enforcing any remedy or right or taking any other action hereunder, the
  Guarantee Trustee (A) may request instructions from the Holders, (B) may
  refrain from enforcing such remedy or right or taking such other action until
  such instructions are received, and (C) shall be protected in acting in
  accordance with such instructions.

  (b) No provision of this Guarantee Agreement shall be deemed to impose any
duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

  Section 3.3.   Indemnity.

  The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold it
harmless against, any loss, liability or expense incurred without negligence or
bad faith on the part of the Guarantee Trustee, arising out of or in connection
with the acceptance or administration of this Guarantee Agreement, including the
costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder. The Guarantee Trustee will not claim or exact any lien or charge on
any Guarantee Payments as a result of any amount due to it under this Guarantee
Agreement.


                        ARTICLE IV.   GUARANTEE TRUSTEE

  (a) There shall at all times be a Guarantee Trustee which shall:

     (i) not be an Affiliate of the Guarantor; and

     (ii) be a Person that is eligible pursuant to the Trust Indenture Act to
  act as such and has a combined capital and surplus of at least $50,000,000,
  and shall be a corporation meeting the requirements of Section 310(a) of the
  Trust Indenture Act. If such corporation publishes reports of condition at
  least annually, pursuant to law or to the requirements of the supervising or
  examining authority, then, for the purposes of this Section and to the extent
  permitted by the Trust Indenture Act, the combined capital and surplus of such
  corporation shall be deemed to be its combined capital and surplus as set
  forth in its most recent report of condition so published.

  (b) If at any time the Guarantee Trustee shall cease to be eligible to so act
under Section 4.1(a), the Guarantee Trustee shall immediately resign in the
manner and with the effect set out in Section 4.2(c).

  (c) If the Guarantee Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Guarantee

  (a) Subject to Section 4.2(b), the Guarantee Trustee may be appointed or
removed without cause at any time by the Guarantor.

  (b) The Guarantee Trustee shall not be removed until a Successor Guarantee
Trustee has been appointed and has accepted such appointment by written
instrument executed by such Successor Guarantee Trustee and delivered to the
Guarantor.

  (c) The Guarantee Trustee appointed hereunder shall hold office until a
Successor Guarantee Trustee shall have been appointed or until its removal or

Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

  (d) If no Successor Guarantee Trustee shall have been appointed and accepted
appointment as provided in this Section 4.2 within 60 days after delivery to the
Guarantor of an instrument of resignation, the resigning Guarantee Trustee may
petition, at the expense of the Guarantor, any court of competent jurisdiction
for appointment of a Successor Guarantee Trustee. Such court may thereupon,
after prescribing such notice, if any, as it may deem proper, appoint a
Successor Guarantee Trustee.

  Section 5.1.   Guarantee.

  The Guarantor irrevocably and unconditionally agrees to pay in full to the
Holders the Guarantee Payments (without duplication of amounts theretofore paid
by or on behalf of the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim which the Issuer may have or assert. The

payment of the required amounts by the Guarantor to the Holders or by causing
the Issuer to pay such amounts to the Holders.

  Section 5.2.   Waiver of Notice and Demand.

  The Guarantor hereby waives notice of acceptance of the Guarantee Agreement

or equitable discharge or defense of a guarantor, it being the intent of this
Section 5.3 that the obligations of the Guarantor hereunder shall be absolute
and unconditional under any and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain the
consent of, the Guarantor with respect to the happening of any of the foregoing.

the Guarantee Trustee in respect of this Guarantee Agreement or exercising any
trust or power conferred upon the Guarantee Trustee under this Guarantee
Agreement; and (iv) any Holder may institute a legal proceeding directly against
the Guarantor to enforce its rights under this Guarantee Agreement, without
first instituting a legal proceeding against the Guarantee Trustee, the Issuer
or any other Person.

payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee

                                       9
<PAGE>
 
Agreement. If any amount shall be paid to the Guarantor in violation of the
preceding sentence, the Guarantor agrees to hold such amount in trust for the
Holders and to pay over such amount to the Holders.

  Section 5.7.   Independent Obligations.

  The Guarantor acknowledges that its obligations hereunder are independent of
the obligations of the Issuer with respect to the Preferred Securities and that

junior in right of payment to all other liabilities of the Guarantor except
those made pari passu or subordinate to such obligations expressly by their
terms.

  Section 6.2.   Pari Passu Guarantees.

  The obligations of the Guarantor under this Guarantee Agreement shall rank

  This Guarantee Agreement shall terminate and be of no further force and effect
upon (i) full payment of the Redemption Price of all Preferred Securities, (ii)
the distribution of Debentures to the Holders in exchange for all of the
Preferred Securities or (iii) full payment of the amounts payable in accordance
with the Trust Agreement upon liquidation of the Issuer. Notwithstanding the
foregoing, this Guarantee Agreement will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder must restore payment
of any sums paid with respect to Preferred Securities or this Guarantee
Agreement.


                         ARTICLE VIII.   MISCELLANEOUS

  Section 8.1.   Successors and Assigns.
