         Peoples Heritage Capital Trust I, a statutory business trust created
under the laws of the State of Delaware (the "Trust"), hereby offers, upon the
terms and subject to the conditions set forth in this Prospectus (as the same
may be amended or supplemented from time to time, the "Prospectus") and in the
accompanying Letter of Transmittal (which together constitute the "Exchange
Offer"), to exchange up to $100,000,000 aggregate Liquidation Amount of its
9.06% Series B Capital Securities (the "New Capital Securities") which have been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
pursuant to a Registration Statement (as defined herein) of which this
Prospectus constitutes a part, for a like Liquidation Amount of its outstanding
9.06% Series A Capital Securities (the "Old Capital Securities"), of which
$100,000,000 aggregate Liquidation Amount is outstanding. Pursuant to the
Exchange Offer, Peoples Heritage Financial Group, Inc., a Maine corporation
("Peoples Heritage" or the "Corporation"), also is offering to exchange (i) its
guarantee of payments of cash distributions and payments on liquidation of the
Trust or redemption of the Old Capital Securities (the "Old Guarantee") for a
like guarantee in respect of the New Capital Securities (the "New Guarantee")
and (ii) all of its outstanding 9.06% Series A Junior Subordinated Deferrable
Interest Debentures due February 1, 2027 (the "Old Junior Subordinated
Debentures") for a like aggregate principal amount of its 9.06% Series B Junior
Subordinated Deferrable Interest Debentures due February 1, 2027 (the "New
Junior Subordinated Debentures"), which New Guarantee and New Junior
Subordinated Debentures also have been registered under the Securities Act. The
Old Capital Securities, the Old Guarantee and the Old Junior Subordinated
Debentures are collectively referred to herein as the "Old Securities" and the
New Capital Securities, the New Guarantee and the New Junior Subordinated
Debentures are collectively referred to herein as the "New Securities."

         The terms of the New Securities are identical in all material respects
to the respective terms of the Old Securities, except that (i) the New
Securities have been registered under the Securities Act and therefore will not
be subject to certain restrictions on transfer under federal and state
securities laws applicable to the Old Securities, (ii) the New Capital
Securities will not provide for any increase in the Distribution rate thereon
and (iii) the New Junior Subordinated Debentures will not provide for any
increase in the interest rate thereon. See "Description of New Securities" and
"Description of Old Securities." The New Capital Securities are being offered
for exchange in order to satisfy certain obligations of the Corporation and the
Trust under a Registration Rights Agreement, dated as of January 31, 1997 (the
"Registration Rights Agreement"), among the Corporation, the Trust and the
Initial Purchasers (as defined herein). In the event that the Exchange Offer is
consummated, any Old Capital Securities which remain outstanding after
consummation of the Exchange Offer and the New Capital Securities issued in the
Exchange Offer will vote together as a single class for purposes of determining
whether holders of the requisite percentage in outstanding Liquidation Amount
thereof have taken certain actions or exercised certain rights under the
Declaration (as defined herein).
                                               (Continued on the following page)

         This Prospectus and the Letter of Transmittal are first being mailed to
all registered holders of Old Capital Securities as of ________ __, 1997.

         SEE "RISK FACTORS" COMMENCING ON PAGE 19 FOR CERTAIN INFORMATION THAT
SHOULD BE CONSIDERED BY HOLDERS IN DECIDING WHETHER TO TENDER OLD CAPITAL
SECURITIES IN THE EXCHANGE OFFER.

  THESE SECURITIES ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF A BANK AND ARE NOT
              INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION
                        OR ANY OTHER GOVERNMENTAL AGENCY.

    THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
         AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR
             HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE
              SECURITIES COMMISSION PASSED UPON THE ACCURACY OR AD-
                  EQUACY OF THIS PROSPECTUS. ANY REPRESENTATION
                     TO THE CONTRARY IS A CRIMINAL OFFENSE.

                The date of this Prospectus is ___________, 1997.
<PAGE>   3
(Continued from the previous page)

         The New Capital Securities and the Old Capital Securities
(collectively, the "Capital Securities") represent beneficial interests in the
assets of the Trust. The Corporation is the owner of all of the beneficial
interests represented by common securities of the Trust (the "Common
Securities," and together with the Capital Securities, the "Trust Securities").
The Trust exists for the sole purpose of issuing the Trust Securities and
investing the proceeds thereof in the Junior Subordinated Debentures (as defined
herein). The Junior Subordinated Debentures will mature on February 1, 2027 (the
"Stated Maturity Date"). The Capital Securities will have a preference over the
Common Securities under certain circumstances with respect to cash distributions
and amounts payable on liquidation, redemption or otherwise. See "Description of
New Securities--Description of Capital Securities--Subordination of Common
Securities."

         As used herein, (i) the "Indenture" means the Indenture, dated as of
January 31, 1997, between the Corporation and The Bank of New York, as Debenture
Trustee (the "Debenture Trustee"), as amended and supplemented from time to
time, and (ii) the "Declaration" means the Amended and Restated Declaration of
Trust relating to the Trust among the Corporation, as Sponsor, The Bank of New
York, as Property Trustee (the "Property Trustee"), The Bank of New York
(Delaware), as the Delaware Trustee (the "Delaware Trustee"), the Administrative
Trustees named therein (collectively, with the Property Trustee and the Delaware
Trustee, the "Issuer Trustees"), and the holders, from time to time, of
undivided beneficial interests in the assets of the Trust, as amended and
supplemented from time to time. In addition, as the context may require, unless
otherwise expressly stated, (i) the term "Capital Securities" means the Old
Capital Securities and the New Capital Securities, (ii) the term "Trust
Securities" means the Capital Securities and the Common Securities, (iii) the
term "Junior Subordinated Debentures" means the Old Junior Subordinated
Debentures and the New Junior Subordinated Debentures and (iv) the term
"Guarantee" means the Old Guarantee and the New Guarantee.

         Except as provided below, the Capital Securities will be represented by
global Capital Securities in fully registered form, deposited with a custodian
for and registered in the name of a nominee of The Depository Trust Company
("DTC"). Beneficial interests in such Capital Securities will be shown on, and
transfers thereof will be effected through, records maintained by DTC and its
participants. Beneficial interests in such Capital Securities will trade in
DTC's Same-Day Funds Settlement system and secondary market trading activity in
such interests will therefore settle in immediately available funds. The Capital
Securities will be issued, and may be transferred, only in blocks having a
Liquidation Amount of not less than $100,000 (100 Capital Securities). See
"Description of New Securities -- Description of Capital Securities -- Form,
Denomination, Book-Entry Procedures and Transfer."

         Holders of the Capital Securities will be entitled to receive
cumulative cash distributions arising from the payment of interest on the Junior
Subordinated Debentures, accruing from January 31, 1997, and payable
semi-annually in arrears on February 1 and August 1 of each year, commencing
August 1, 1997 at the annual rate of 9.06% of the Liquidation Amount of $1,000
per Capital Security ("Distributions"). The Corporation has the right to defer
payments of interest on the Junior Subordinated Debentures at any time and from
time to time for a period not exceeding 10 consecutive semi-annual periods with
respect to each deferral period (each, an "Extension Period"), provided that no
Extension Period may extend beyond the Stated Maturity Date. Upon the
termination of any such Extension Period and the payment of all amounts then
due, the Corporation may elect to begin a new Extension Period, subject to the
requirements set forth in the Indenture. If and for so long as interest payments
on the Junior Subordinated Debentures are so deferred, Distributions on the
Trust Securities also will 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 (which
includes common and preferred stock) or to make any payment with respect to debt
securities of the Corporation that rank pari passu with or junior to the Junior
Subordinated Debentures. During an Extension Period, interest on the Junior
Subordinated Debentures will continue to accrue (and the amount of Distributions
to which holders of the Trust Securities are entitled will accumulate) at the
rate of 9.06% per annum, compounded semi-annually, and holders


                                        2
<PAGE>   4
(Continued from the previous page)

of Trust Securities will be required to accrue interest income for United States
federal income tax purposes. See "Description of New Securities--Description of
Junior Subordinated Debentures--Option to Extend Interest Payment Date" and
"Certain United States Federal Income Tax Considerations--Interest Income and
Original Issue Discount."

         The Corporation has, through the Guarantee, the guarantee agreement of
the Corporation relating to the Common Securities (the "Common Guarantee"), the
Declaration, the Junior Subordinated Debentures and the Indenture, taken
together, fully, irrevocably and unconditionally guaranteed all of the Trust's
obligations under the Trust Securities. See "Relationship Among the Capital
Securities, the Junior Subordinated Debentures and the Guarantee--Full and
Unconditional Guarantee." The Guarantee and the Common Guarantee guarantee
payments of Distributions and payments on liquidation or redemption of the Trust
Securities, but in each case only to the extent that the Trust holds funds on
hand legally available therefor and has failed to make such payments, as
described herein. See "Description of New Securities--Description of Guarantee."
If the Corporation fails to make a required payment on the Junior Subordinated
Debentures, the Trust does not have sufficient funds to make the related
payments, including Distributions, on the Trust Securities. The Guarantee and
the Common Guarantee do not cover any such payment when the Trust does not have
sufficient funds on hand legally available therefor. In such event, under the
Indenture a holder of Capital Securities may institute a legal proceeding
directly against the Corporation to enforce its rights in respect of such
payment. See "Description of New Securities--Description of Junior Subordinated
Debentures--Enforcement of Certain Rights By Holders of New Capital Securities."
The obligations of the Corporation under the Guarantee, the Common Guarantee and
the Junior Subordinated Debentures are unsecured and rank subordinate and junior
in right of payment to all Senior Indebtedness of the Corporation to the extent
and in the manner set forth in the Indenture. See "Description of New
Securities--Description of Junior Subordinated Debentures--Subordination." In
addition, because the Corporation is a holding company, the Junior Subordinated
Debentures and the Guarantee effectively are subordinated to all existing and
future liabilities, including deposits, of the Corporation's subsidiaries.

         The Trust Securities are subject to mandatory redemption in a Like
Amount (as defined herein), (i) in whole but not in part, on the Stated Maturity
Date upon repayment of the Junior Subordinated Debentures at a redemption price
equal to the principal amount of, plus accrued interest on, the Junior
Subordinated Debentures (the "Maturity Redemption Price"), (ii) in whole but not
in part, at any time before February 1, 2007 (the "Initial Optional Prepayment
Date"), contemporaneously with the optional redemption of the Junior
Subordinated Debentures, upon the occurrence and continuation of a Special Event
(as defined herein) at a redemption price equal to the Special Event Prepayment
Price (as defined below) (the "Special Event Redemption Price") and (iii) in
whole or in part, on or after the Initial Optional Prepayment Date,
contemporaneously with the optional redemption by the Corporation of the Junior
Subordinated Debentures, at a redemption price equal to the Optional Prepayment
Price (as defined below) (the "Optional Redemption Price"). Any of the Maturity
Redemption Price, the Special Event Redemption Price and the Optional
Redemption Price may be referred to herein as the "Redemption Price." See
"Description of New Securities--Description of Capital Securities--Redemption."

         Subject to the Corporation having received prior approval of the Board
of Governors of the Federal Reserve System (the "Federal Reserve"), if then
required under applicable capital guidelines or policies of the Federal Reserve,
the Junior Subordinated Debentures will be redeemable prior to the Stated
Maturity Date at the option of the Corporation (i) on or after the Initial
Optional Prepayment Date, in whole or in part, at a prepayment price (the
"Optional Prepayment Price") equal to 104.53% of the principal amount thereof on
the Initial Optional Prepayment Date, declining ratably on each February 1
thereafter to 100% on or after February 1, 2017, plus accrued and unpaid
interest thereon to the date of redemption, or (ii) at any time before the
Initial Optional Prepayment Date, in whole but not in part, upon the occurrence
and continuation of a Special Event, at a prepayment price (the "Special Event
Prepayment Price") equal to the greater of (a) 100% of the principal


                                        3
<PAGE>   5
(Continued from the previous page)

amount thereof or (b) the sum, as determined by a Quotation Agent (as defined
herein), of the present values of the principal amount and premium payable as
part of the Optional Prepayment Price with respect to an optional redemption of
such Junior Subordinated Debentures on the Initial Optional Prepayment Date,
together with scheduled payments of interest from the redemption date to the
Initial Optional Prepayment Date, in each case discounted to the redemption date
on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Adjusted Treasury Rate (as defined herein) plus in either case
accrued and unpaid interest thereon to the date of redemption. Either of the
Optional Prepayment Price or the Special Event Prepayment Price may be referred
to herein as the "Prepayment Price." See "Description of New
Securities--Description of Junior Subordinated Debentures--Optional Redemption"
and "--Special Event Prepayment."

         The Corporation, as the holder of the outstanding Common Securities,
has the right at any time (including without limitation upon the occurrence of a
Tax Event (as defined herein)) to terminate the Trust and, in the event of such
a termination, after satisfaction of liabilities to creditors of the Trust as
required by applicable law, the holders of the Capital Securities generally will
be entitled to receive a Liquidation Amount of $1,000 per Capital Security plus
accumulated and unpaid Distributions thereon to the date of payment, which may
be in the form of a distribution of a Like Amount (as defined herein) in Junior
Subordinated Debentures, subject to certain exceptions. See "Description of New
Securities--Description of Capital Securities--Liquidation of the Trust and
Distribution of Junior Subordinated Debentures," and "Certain Federal Income Tax
Considerations--Receipt of Junior Subordinated Debentures or Cash upon
Liquidation of the Trust."



         The Trust is making the Exchange Offer of the New Capital Securities in
reliance on the position of the staff of the Division of Corporation Finance of
the Securities and Exchange Commission (the "Commission") as set forth in
certain interpretive letters addressed to third parties in other transactions.
However, neither the Corporation nor the Trust has sought its own interpretive
letter and there can be no assurance that the staff of the Division of
Corporation Finance of the Commission would make a similar determination with
respect to the Exchange Offer as it has in such interpretive letters to third
parties. Based on these interpretations by the staff of the Division of
Corporation Finance of the Commission, and subject to the two immediately
following sentences, the Corporation and the Trust believe that New Capital
Securities issued pursuant to this Exchange Offer in exchange for Old Capital
Securities may be offered for resale, resold and otherwise transferred by a
holder thereof (other than a holder who is a broker-dealer) without further
compliance with the registration and prospectus delivery requirements of the
Securities Act, provided that such New Capital Securities are acquired in the
ordinary course of such holder's business and that such holder is not
participating, and has no arrangement or understanding with any person to
participate, in a distribution (within the meaning of the Securities Act) of
such New Capital Securities. However, any holder of Old Capital Securities who
is an "affiliate" of the Corporation or the Trust within the meaning of Rule 405
under the Securities Act (an "Affiliate") or who intends to participate in the
Exchange Offer for the purpose of distributing New Capital Securities, or any
broker-dealer who purchased Old Capital Securities from the Trust to resell
pursuant to Rule 144A under the Securities Act ("Rule 144A") or any other
available exemption under the Securities Act, (i) will not be able to rely on
the interpretations of the staff of the Division of Corporation Finance of the
Commission set forth in the above-mentioned interpretive letters, (ii) will not
be entitled to tender such Old Capital Securities in the Exchange Offer and
(iii) must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any sale or other transfer of such Old
Capital Securities (other than pursuant to the Exchange Offer) unless such sale
is made pursuant to an exemption from such requirements. In addition, as
described below, if any broker-dealer (a "Participating Broker-Dealer") holds
Old Capital Securities acquired for its own account as a result of market-making
or other trading activities and exchanges such Old Capital Securities for New
Capital Securities, then such Participating Broker-Dealer must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resales of such New Capital Securities.

(Continued from the previous page)

         Each holder of Old Capital Securities who wishes to exchange Old
Capital Securities for New Capital Securities in the Exchange Offer will be
required to represent that (i) it is not an Affiliate of the Corporation or the
Trust, (ii) any New Capital Securities to be received by it are being acquired
in the ordinary course of its business, (iii) it has no arrangement or
understanding with any person to participate in a distribution (within the
meaning of the Securities Act) of such New Capital Securities, and (iv) if such
holder is not a broker-dealer, such holder is not engaged in, and does not
intend to engage in, a distribution (within the meaning of the Securities Act)
of such New Capital Securities. The Letter of Transmittal contains the foregoing
representations. In addition, the Corporation and the Trust may require such
holder, as a condition to such holder's eligibility to participate in the
Exchange Offer, to furnish to the Corporation and the Trust (or an agent
thereof) in writing information as to the number of "beneficial owners" (within
the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended
(the "Exchange Act")) on behalf of whom such holder holds Old Capital Securities
to be exchanged in the Exchange Offer. Each Participating Broker-Dealer that
receives New Capital Securities for its own account pursuant to the Exchange
Offer will be deemed to have acknowledged by execution of the Letter of
Transmittal or delivery of an Agent's Message (as defined herein) that it
acquired the Old Capital Securities for its own account as the result of
market-making activities or other trading activities and must agree that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such New Capital Securities. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
Participating Broker-Dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. Based on the position
taken by the staff of the Division of Corporation Finance of the Commission in
the interpretive letters referred to above, the Corporation and the Trust
believe that Participating Broker-Dealers may fulfill their prospectus delivery
requirements with respect to the New Capital Securities received upon exchange
of such Old Capital Securities (other than Old Capital Securities which
represent an unsold allotment from the original sale of the Old Capital
Securities) with a prospectus meeting the requirements of the Securities Act,
which may be the prospectus prepared for an exchange offer so long as it
contains a description of the plan of distribution with respect to the resale of
such New Capital Securities. Accordingly, this Prospectus, as it may be amended
or supplemented from time to time, may be used by a Participating Broker-Dealer
during the period referred to below in connection with resales of New Capital
Securities received in exchange for Old Capital Securities where such Old
Capital Securities were acquired by such Participating Broker-Dealer for its own
account as a result of market-making or other trading activities. Subject to
certain provisions set forth in the Registration Rights Agreement, the
Corporation and the Trust have agreed that this Prospectus, as it may be amended
or supplemented from time to time, may be used by a Participating Broker-Dealer
in connection with resales of such New Capital Securities for a period ending
90-days after the Expiration Date (as defined herein) (subject to extension
under certain limited circumstances described below) or, if earlier, when all
such New Capital Securities have been disposed of by such Participating
Broker-Dealer. See "Plan of Distribution." However, a Participating
Broker-Dealer who intends to use this Prospectus in connection with the resale
of New Capital Securities received in exchange for Old Capital Securities
pursuant to the Exchange Offer must notify the Corporation or the Trust, or
cause the Corporation or the Trust to be notified, on or prior to the Expiration
Date, that it is a Participating Broker-Dealer. Such notice may be given in the
space provided for that purpose in the Letter of Transmittal or may be delivered
to the Exchange Agent at one of the addresses set forth herein under "The
Exchange Offer--Exchange Agent." Any person, including any Participating
Broker-Dealer, who is an Affiliate of the Corporation or the Trust may not rely
on such interpretive letters and must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction. See "The Exchange Offer--Resales of New Capital Securities."

         In that regard, each Participating Broker-Dealer who surrenders Old
Capital Securities pursuant to the Exchange Offer will be deemed to have agreed,
by execution of the Letter of Transmittal or delivery of an Agent's Message,
that, upon receipt of notice from the Corporation or the Trust of the occurrence
of any event or the discovery of any fact which makes any statement contained or
incorporated by reference in this Prospectus untrue in any material respect or
which causes this Prospectus to omit to state a material fact necessary in order
to make the statements contained or incorporated by reference herein, in light
of the circumstances under which


                                        5
<PAGE>   7
(Continued from the previous page)

they were made, not misleading or of the occurrence of certain other events
specified in the Registration Rights Agreement, such Participating Broker-Dealer
will suspend the sale of New Capital Securities (or the New Guarantee or the New
Junior Subordinated Debentures, as applicable) pursuant to this Prospectus until
the Corporation or the Trust has amended or supplemented this Prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemented Prospectus to such Participating Broker-Dealer or the Corporation
or the Trust has given notice that the sale of the New Capital Securities (or
the New Guarantee or the New Junior Subordinated Debentures, as applicable) may
be resumed, as the case may be. If the Corporation or the Trust gives such
notice to suspend the sale of the New Capital Securities (or the New Guarantee
or the New Junior Subordinated Debentures, as applicable), it shall extend the
90-day period referred to above during which Participating Broker-Dealers are
entitled to use this Prospectus in connection with the resale of New Capital
Securities by the number of days during the period from and including the date
of the giving of such notice to and including the date when Participating
Broker-Dealers shall have received copies of the amended or supplemented
Prospectus necessary to permit resales of the New Capital Securities or to and
including the date on which the Corporation or the Trust has given notice that
the sale of New Capital Securities (or the New Guarantee or the New Junior
Subordinated Debentures, as applicable) may be resumed, as the case may be.

         Prior to the Exchange Offer, there has been only a limited secondary
market and no public market for the Old Capital Securities. The New Capital
Securities will be a new issue of securities for which there currently is no
market. There can be no assurance as to the development or liquidity of any
market for the New Capital Securities. The Corporation and the Trust currently
do not intend to apply for listing of the New Capital Securities on any
securities exchange or for quotation through the National Association of
Securities Dealers Automated Quotation System.

         Any Old Capital Securities not tendered and accepted in the Exchange
Offer will remain outstanding and will be entitled to all the same rights and
will be subject to the same limitations applicable thereto under the Declaration
(except for those rights which terminate upon consummation of the Exchange
Offer). Following consummation of the Exchange Offer, the holders of Old Capital
Securities will continue to be subject to all of the existing restrictions upon
transfer thereof and neither the Corporation nor the Trust will have any further
obligation to such holders to provide for registration under the Securities Act
of the Old Capital Securities held by them. To the extent that Old Capital
Securities are tendered and accepted in the Exchange Offer, a holder's ability
to sell untendered Old Capital Securities could be adversely affected. See "Risk
Factors--Consequences of a Failure to Exchange Old Capital Securities."

         THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD CAPITAL SECURITIES ARE URGED TO READ THIS PROSPECTUS
AND THE RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO
TENDER THEIR OLD CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER.

         Old Capital Securities may be tendered for exchange on or prior to 5:00
p.m., New York City time, on ________ __, 1997 (such time on such date being
hereinafter called the "Expiration Date"), unless the Exchange Offer is extended
by the Corporation or the Trust (in which case the term "Expiration Date" shall
mean the latest date and time to which the Exchange Offer is extended). Tenders
of Old Capital Securities may be withdrawn at any time on or prior to the
Expiration Date. The Exchange Offer is not conditioned upon any minimum
Liquidation Amount of Old Capital Securities being tendered for exchange.
However, the Exchange Offer is subject to certain events and conditions which
may be waived by the Corporation or the Trust and to the provisions of the
Registration Rights Agreement. Old Capital Securities may be tendered in whole
or in part having an aggregate Liquidation Amount of not less than $100,000 (100
Capital Securities) and/or any integral multiple of $1,000 Liquidation Amount
(one Capital Security) in excess thereof. The Corporation has agreed

to pay all expenses of the Exchange Offer. See "The Exchange Offer--Fees and
Expenses." Holders of New Capital Securities as of the record date for the
payment of Distributions on August 1, 1997 will be entitled to receive
Distributions accumulated from and including January 31, 1997. Holders of the
Old Capital Securities whose Old Capital Securities are accepted for exchange
will not receive Distributions on such Old Capital Securities and will be deemed
to have waived the right to receive any Distributions on such Old Capital
Securities accumulated from and after January 31, 1997. See "The Exchange
Offer--Distributions on New Capital Securities." This Prospectus, together with
the Letter of Transmittal, is being sent to all registered holders of Old
Capital Securities as of _________ ___, 1997.

         Neither the Corporation nor the Trust will receive any cash proceeds
from the issuance of the New Capital Securities offered hereby. No
dealer-manager is being used in connection with this Exchange Offer. See "Use of
Proceeds" and "Plan of Distribution."

                  THE NEW CAPITAL SECURITIES WILL BE ISSUED, AND CAPITAL
SECURITIES MAY BE TRANSFERRED, ONLY IN BLOCKS HAVING A LIQUIDATION AMOUNT OF NOT
LESS THAN $100,000. ANY TRANSFER, SALE OR OTHER DISPOSITION OF CAPITAL
SECURITIES IN A BLOCK HAVING A LIQUIDATION AMOUNT OF LESS THAN $100,000 SHALL BE
DEEMED TO BE VOID AND OF NO LEGAL EFFECT WHATSOEVER. ANY SUCH TRANSFEREE SHALL
BE DEEMED NOT TO BE LIMITED TO THE RECEIPT OF DISTRIBUTIONS ON SUCH CAPITAL
SECURITIES, AND SUCH TRANSFEREE SHALL BE DEEMED TO HAVE NO INTEREST WHATSOEVER
IN SUCH CAPITAL SECURITIES.

will file reports, proxy statements and other information under the Exchange Act
with the Commission.

Resales of New Capital 
  Securities....................        The Corporation and the Trust are making
                                        the Exchange Offer in reliance on the
                                        position of the staff of the Division of
                                        Corporation Finance of the Commission as
                                        set forth in certain interpretive
                                        letters addressed to third parties in
                                        other transactions. However, neither the
                                        Corporation nor the Trust has sought its
                                        own interpretive letter and there can be
                                        no assurance that the staff of the
                                        Division of Corporation Finance of the
                                        Commission would make a similar
                                        determination with respect to the
                                        Exchange Offer as it has in such
                                        interpretive letters to third parties.
                                        Based on these interpretations by the
                                        staff of the Division of Corporation
                                        Finance of the Commission, and subject
                                        to the two immediately following
                                        sentences, the Corporation and the Trust
                                        believe that New Capital Securities
                                        issued pursuant to this Exchange Offer
                                        in exchange for Old Capital Securities
                                        may be offered for resale, resold and
                                        otherwise transferred by a holder
                                        thereof (other than a holder who is a
                                        broker-dealer) without further
                                        compliance with the registration and
                                        prospectus delivery requirements of the
                                        Securities Act, provided that such New

                                        ordinary course of such holder's
                                        business and that such holder is not
                                        participating, and has no arrangement or
                                        understanding with any person to
                                        participate, in a distribution (within
                                        the meaning of the Securities Act) of
                                        such New Capital Securities. However,
                                        any holder of Old Capital Securities who
                                        is an Affiliate of the Corporation or
                                        the Trust or who intends to participate
                                        in the Exchange Offer for the purpose of
                                        distributing the New Capital Securities,
                                        or any broker-dealer who purchased the
                                        Old Capital Securities from the Trust to

                                        other available exemption under the
                                        Securities Act, (i) will not be able to

                                        of the Division of Corporation Finance
                                        of the Commission set forth in the

                                        Indebtedness of the Corporation to the
                                        extent and in the manner set forth in
                                        the Guarantee Agreement. See
                                        "Description of New
                                        Securities--Description of Guarantee."

Redemption......................        The Trust Securities are subject to
                                        mandatory redemption in a Like Amount,
                                        (i) in whole but not in part, on the
                                        Stated Maturity Date upon repayment of
                                        the Junior Subordinated Debentures, (ii)
                                        in whole but not in part, at any time
                                        before the Initial Optional Prepayment
                                        Date contemporaneously with the optional
                                        redemption of the Junior Subordinated
                                        Debentures by the Corporation upon the
                                        occurrence and continuation of a Special
                                        Event (as defined herein) and (iii) in
                                        whole or in part, at any time on or
                                        after the Initial Optional Prepayment
                                        Date contemporaneously with the optional
                                        redemption by the Corporation of the
                                        Junior Subordinated Debentures, in each
                                        case at the applicable Redemption Price.
                                        See "Description of New
                                        Securities--Description of Capital
                                        Securities--Redemption."

Rating..........................        The New Capital Securities are expected
                                        to be rated "ba1" by Moody's Investors
                                        Service, Inc., "BB+" by Standard &
                                        Poor's Ratings Services and "BBB" by
                                        Thomson BankWatch, Inc., which are the
                                        ratings which such agencies have given
                                        to the Old Capital Securities. A
                                        security rating is not a recommendation
                                        to buy, sell or hold securities and may
                                        be subject to revision or withdrawal at
                                        any time by the assigning rating
                                        organization.

Transfer........................        The Capital Securities will be issued,
                                        and may be transferred, only in blocks
                                        having a Liquidation Amount of not less
                                        than $100,000 (100 Capital Securities).
                                        Any transfer, sale or other disposition
                                        of Capital Securities resulting in a
                                        block having a Liquidation Amount of
                                        less than $100,000 shall be deemed to be
                                        void and of no legal effect whatsoever.

Absence of Market for the New 
  Capital Securities............        The New Capital Securities will be a new
                                        issue of securities for which there
                                        currently is no market. Each of Keefe,
                                        Bruyette & Woods, Inc. and Lehman
                                        Brothers, the initial purchasers of the
                                        Old Capital Securities (the "Initial
                                        Purchasers"), informed the Corporation
                                        and the Trust in connection with the
                                        offering of the Old Capital Securities
                                        that it intends to make a market in the
                                        Old Capital Securities. However, neither
                                        Initial Purchaser is obligated to make a
                                        market in the Old Capital Securities or
                                        the New Capital Securities, and any such

                                        notice. Accordingly, there can be no
                                        assurance as to the development or
                                        liquidity of any market for the Capital
                                        Securities. The Trust and the
                                        Corporation do not intend to apply for
                                        listing of the Capital Securities on any
                                        securities exchange or for quotation

                                  RISK FACTORS

         Prospective investors should consider carefully, in addition to the
other information contained in this Prospectus, the following factors in
connection with the Exchange Offer and the New Capital Securities offered
hereby.

RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE JUNIOR
SUBORDINATED DEBENTURES

         The obligations of the Corporation under the Guarantee for the benefit
of holders of Capital Securities and under the Junior Subordinated Debentures
are unsecured and rank subordinate and junior in right of payment to all present
and future Senior Indebtedness of the Corporation to the extent and in the
manner set forth in the Indenture and the Guarantee, respectively. No payment
may be made of the principal of, or premium, if any, or interest on the Junior
Subordinated Debentures, or in respect of any redemption, retirement, purchase
or other acquisition of any of the Junior Subordinated Debentures, at any time
when (i) there shall have occurred and be continuing a default, in any payment
in respect of any Senior Indebtedness, or there has been an acceleration of the
maturity thereof because of a default, or (ii) in the event of the acceleration
of the maturity of the Junior Subordinated Debentures until payment has been
made on all Senior Indebtedness. At December 31, 1996, the aggregate principal
amount of outstanding Senior Indebtedness of the Corporation was approximately
$6.5 million. Because the Corporation is a bank 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 (and thus the
ability of holders of the Capital Securities to benefit indirectly from such
distribution) 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 such subsidiary. At December 31, 1996, the subsidiaries of the Corporation
had total liabilities (excluding liabilities owed to the Corporation) of
approximately $5.0 billion, including deposits. Accordingly, the Junior
Subordinated Debentures effectively will be 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. In addition, the bank
subsidiaries of the Corporation (the "Banks") are subject to certain
restrictions imposed by federal law on any extensions of credit to, and certain
other transactions with, the Corporation and certain other affiliates, and on
investments in stock or other securities thereof. Such restrictions prevent the
Corporation and such other affiliates from borrowing from the Banks unless the
loans are secured by various types of collateral. Further, such secured loans,
other transactions and investments by any of the Banks are generally limited in
amount as to the Corporation and as to each of such other affiliates to 10% of
such Bank's capital and surplus and as to the Corporation and all of such other
affiliates to an aggregate of 20% of such Bank's capital and surplus. In
addition, payment of dividends to the Corporation by the Banks is subject to
ongoing review by banking regulators and is subject to various statutory
limitations and in certain circumstances requires approval by banking regulatory
authorities. The Guarantee constitutes an unsecured obligation of the
Corporation and ranks subordinate and junior in right of payment to all Senior
Indebtedness of the Corporation in the same manner as the Junior Subordinated
Debentures. None of the Indenture, the Guarantee or the Declaration places any
limitation on the amount of secured or unsecured debt, including Senior
Indebtedness, that may be incurred by the Corporation or any of its
subsidiaries. See "Description of New Securities -- Description of Guarantee
- -Status of Guarantee" and "-- Description of Junior Subordinated Debentures --
Subordination."

         The ability of the Trust to pay amounts due on the Capital Securities
is dependent upon the Corporation making payments on the Junior Subordinated
Debentures as and when required.

OPTION TO EXTEND INTEREST PAYMENT PERIOD; MARKET PRICE CONSEQUENCES

         So long as no Debenture Event of Default (as defined herein) shall have
occurred and be continuing, the Corporation has the right under the Indenture to
defer the payment of interest on the Junior Subordinated Debentures at any time
or from time to time for a period not exceeding 10 consecutive semi-annual
periods with


                                       19
<PAGE>   21
respect to each Extension Period, provided that no Extension Period may extend
beyond the Stated Maturity Date. As a consequence of any such deferral,
semi-annual Distributions on the Capital Securities by the Trust will be
deferred (and the amount of Distributions to which holders of the Capital
Securities are entitled will accumulate additional Distributions thereon at the
rate of 9.06% per annum, compounded semi-annually) from the relevant payment
date for such Distributions during any such Extension Period.

         The Corporation may extend any existing Extension Period, provided that
such extension does not cause such Extension Period to exceed 10 consecutive
semi-annual periods or to extend beyond the Stated Maturity Date. Upon the
expiration of any Extension Period and the payment of all interest then accrued
and unpaid on the Junior Subordinated Debentures (together with interest thereon
at the annual rate of 9.06%, compounded semi-annually, 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 "Description of
New Securities -- Description of Capital Securities -- Distributions" and "--
Description of Junior Subordinated Debentures -- Option to Extend Interest
Payment Date."

         Should the Corporation exercise its right to defer payments of interest
on the Junior Subordinated Debentures, each holder of Capital Securities will be
required to accrue income (as original issue discount ("OID")) in respect of the
deferred stated interest allocable to its Capital Securities for United States
federal income tax purposes, which will be allocated but not distributed to
holders of Capital Securities. As a result, during an Extension Period, each
holder of Capital Securities will recognize income for United States federal
income tax purposes in advance of the receipt of cash and will not receive the
cash related to such income from the Trust if the holder disposes of the Capital
Securities prior to the record date for the payment of Distributions thereafter.
See "Certain United States Federal Income Tax Considerations -- Interest Income
and Original Issue Discount" and "-- Sales of Capital Securities."

         The Corporation has no current plan to exercise its right to defer
payments of interest on the Junior Subordinated Debentures. Should the
Corporation elect to exercise its right to defer payments of interest on the
Junior Subordinated Debentures, the market price of the Capital Securities is
likely to be affected. A holder that disposes of its Capital Securities during
an Extension Period, therefore, might not receive the same return on its
investment as a holder that continues to hold its Capital Securities. In
addition, the mere existence of the Corporation's right to defer payments of
interest on the Junior Subordinated Debentures may cause the market price of the
Capital Securities to be more volatile than the market prices of other
securities that are not subject to such deferrals.

REDEMPTION; POSSIBLE TAX LAW CHANGES AFFECTING THE CAPITAL SECURITIES

         Upon the occurrence and continuation of a Special Event (as defined
under "Description of New Securities--Description of Junior Subordinated
Debentures--Special Event Prepayment"), the Corporation has the right to redeem
the Junior Subordinated Debentures, before the Initial Optional Prepayment Date,
in whole (but not in part) at the Special Event Prepayment Price within 90 days
following the occurrence of such Special Event and therefore cause a mandatory
redemption of the Trust Securities at the Special Event Redemption Price. On or
after the Initial Optional Prepayment Date, the Corporation may redeem the
Junior Subordinated Debentures in whole or in part for any reason and thereby
cause an optional redemption of the Capital Securities, in whole or in part, at
the Optional Redemption Price. Any such redemption is subject to the Corporation
having received prior approval of the Federal Reserve if then required under
applicable capital guidelines or policies of the Federal Reserve. See
"Description of New Securities--Description of Capital Securities--Redemption."


                                       20
<PAGE>   22
         On February 6, 1997, as part of President Clinton's Fiscal 1998 Budget
Proposal, the United States Treasury Department proposed legislation that would,
among other things, deny an issuer a deduction for United States federal income
tax purposes for the payment of interest on instruments with characteristics
similar to the Junior Subordinated Debentures. If the proposed legislation were
enacted in its current form, it is not expected to apply to the Junior
Subordinated Debentures since the proposed effective date for this provision is
the date of first committee action. There can be no assurances, however, that
the proposed legislation, if enacted, or similar legislation enacted after the
date hereof would not adversely affect the tax treatment of the Junior
Subordinated Debentures, resulting in a Tax Event. The occurrence of a Tax Event
may result in the redemption of the Junior Subordinated Debentures for cash, in
which event the holders of the Capital Securities would receive cash in
redemption of their Capital Securities. See "Description of New
Securities--Description of Capital Securities--Redemption" and "--Description of
Junior Subordinated Debentures--Special Event Prepayment." See also "Certain
Federal Income Tax Considerations - Tax Legislation."

LIQUIDATION DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES

         The Corporation has the right at any time to terminate the Trust and,
after satisfaction of liabilities to creditors of the Trust as required by
applicable law, to cause the Junior Subordinated Debentures to be distributed to
the holders of the Trust Securities in liquidation of the Trust. Under current
United States federal income tax law, a distribution of Junior Subordinated
Debentures upon the dissolution of the Trust would not be a taxable event to
holders of the Capital Securities. If, however, the Trust is characterized for
United States federal income tax purposes as an association taxable as a
corporation at the time of dissolution of the Trust, the distribution of the
Junior Subordinated Debentures may constitute a taxable event to holders of
Capital Securities. Moreover, upon the occurrence of a Special Event, a
dissolution of the Trust in which holders of the Capital Securities receive cash
would be a taxable event to such holders. See "Certain Federal Income Tax
Considerations -- Receipt of Junior Subordinated Debentures or Cash Upon
Liquidation of the Trust."

         There can be no assurance as to the market prices for Capital
Securities or the Junior Subordinated Debentures that may be distributed to the
holders of Capital Securities if a termination of the Trust were to occur.
Accordingly, the Capital Securities or the Junior Subordinated Debentures may
trade at a discount from the price that the investor paid to purchase the
Capital Securities. Because holders of Capital Securities may receive Junior
Subordinated Debentures on termination of the Trust and because Distributions
are otherwise limited to payments on the Junior Subordinated Debentures,
prospective purchasers of Capital Securities are also making an investment
decision with regard to the Junior Subordinated Debentures and should carefully
review all the information regarding the Junior Subordinated Debentures
contained herein. See "Description of New Securities--Description of Junior
Subordinated Debentures."

RIGHTS UNDER THE GUARANTEE

         The Guarantee guarantees to the holders of the Capital Securities the
following payments, to the extent not paid by the Trust: (i) any accumulated and
unpaid Distributions required to be paid on the Capital Securities, to the
extent that the Trust has funds on hand legally available therefor; (ii) the
applicable Redemption Price with respect to any Capital Securities called for
redemption, to the extent that the Trust has funds on hand legally available
therefor; and (iii) upon a voluntary or involuntary termination, winding up or
liquidation of the Trust (unless the Junior Subordinated Debentures are
distributed to holders of the Capital 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 Trust has funds on hand legally
available therefor on such date, and (b) the amount of assets of the Trust
remaining available for distribution to holders of the Capital Securities on
such date after satisfaction of liabilities to creditors of the Trust as
provided by applicable law. The holders of not less than a majority in
Liquidation Amount of the Capital Securities have the right to direct the time,
method and place of conducting any proceeding for any remedy available in
respect of the Guarantee or to direct the exercise of any trust power conferred
upon the Guarantee Trustee under the Indenture. Any holder of the


                                       21
<PAGE>   23
Capital Securities may institute a legal proceeding directly against the
Corporation to enforce its rights under the Guarantee without first instituting
a legal proceeding against the Trust, the Guarantee Trustee or any other person
or entity. If the Corporation were to default on its obligation to pay amounts
payable under the Junior Subordinated Debentures, the Trust would not have
sufficient funds for the payment of Distributions or amounts payable on
redemption of the Capital Securities or otherwise, and, in such event, holders
of the Capital Securities would not be able to rely upon the Guarantee for
payment of such amounts. Instead, in the event a Debenture Event of Default
shall have occurred and be continuing and such event is attributable to the
failure of the Corporation to pay principal of or premium, if any, or interest
on the Junior Subordinated Debentures on the payment date on which such payment
is due and payable, then a holder of Capital Securities may institute a legal
proceeding directly against the Corporation for enforcement of payment to such
holder of the principal of or premium, if any, or interest on such Junior
Subordinated Debentures having a principal amount equal to the Liquidation
Amount of the Capital Securities of such holder (a "Direct Action").
Notwithstanding any payments made to a holder of Capital Securities by the
Corporation in connection with a Direct Action, the Corporation shall remain
obligated to pay the principal of and premium, if any, and interest on the
Junior Subordinated Debentures, and the Corporation shall be subrogated to the
rights of the holder of such Capital Securities with respect to payments on the
Capital Securities to the extent of any payments made by the Corporation to such
holder in any Direct Action. Except as described herein, holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Junior Subordinated Debentures or to assert directly any
other rights in respect of the Junior Subordinated Debentures. See "Description
of New Securities--Description of Junior Subordinated Debentures--Enforcement of
Certain Rights by Holders of Capital Securities," "--Description of Junior
Subordinated Debentures--Debenture Events of Default" and "--Description of
Guarantee." The Declaration provides that each holder of Capital Securities by
acceptance thereof agrees to the provisions of the Guarantee and the Indenture.
The Bank of New York acts as Guarantee Trustee and holds the Guarantee for the
benefit of the holders of the Capital Securities. The Bank of New York also acts
as Property Trustee and as Debenture Trustee under the Indenture. The Bank of
New York (Delaware) acts as Delaware Trustee under the Declaration.

LIMITED VOTING RIGHTS

         Holders of Capital Securities generally will have limited voting rights
relating only to the modification of the terms of the Capital Securities and the
exercise of the Trust's rights as holder of the Junior Subordinated Debentures
and the Guarantee. Holders of Capital Securities will not be entitled to vote to
appoint, remove or replace, or to increase or decrease the number of, the Issuer
Trustees, which voting rights are vested exclusively in the holder of the Common
Securities, except as described under "Description of New
Securities--Description of Capital Securities--Voting Rights; Amendment of the
Declaration" and "--Removal of Issuer Trustees."

CONSEQUENCES OF A FAILURE TO EXCHANGE OLD CAPITAL SECURITIES

         The Old Capital Securities have not been registered under the
Securities Act or any state securities laws and therefore may not be offered,
sold or otherwise transferred except in compliance with the registration
requirements of the Securities Act and any other applicable securities laws, or
pursuant to an exemption therefrom or in a transaction not subject thereto, and
in each case in compliance with certain other conditions and restrictions. Old
Capital Securities which remain outstanding after consummation of the Exchange
Offer will continue to bear a legend reflecting such restrictions on transfer.
In addition, upon consummation of the Exchange Offer, holders of Old Capital
Securities which remain outstanding will not be entitled to any rights to have
such Old Capital Securities registered under the Securities Act or to any
similar rights under the Registration Rights Agreement. The Corporation and the
Trust do not intend to register under the Securities Act any Old Capital
Securities which remain outstanding after consummation of the Exchange Offer.

         To the extent that Old Capital Securities are tendered and accepted in
the Exchange Offer, a holder's ability to sell untendered Old Capital Securities
could be adversely affected. In addition, although the Old


                                       22
<PAGE>   24
Capital Securities have been designated for trading in the Private Offerings,
Resale and Trading through Automated Linkages ("PORTAL") market, to the extent
that Old Capital Securities are tendered and accepted in connection with the
Exchange Offer, any trading market for Old Capital Securities which remain
outstanding after the Exchange Offer could be adversely affected.

         The New Capital Securities and any Old Capital Securities which remain
outstanding after consummation of the Exchange Offer will vote together as a
single class for purposes of determining whether holders of the requisite
percentage in outstanding Liquidation Amount thereof have taken certain actions
or exercised certain rights under the Declaration. See "Description of New
Securities--Description of Capital Securities--Voting Rights; Amendment of the
Declaration."

         The Old Capital Securities provide, among other things, that, if a
registration statement relating to the Exchange Offer has not been filed by June
30, 1997 and declared effective by July 30, 1997, the Distribution rate borne by
the Old Capital Securities commencing on January 31, 1997 will increase by 0.25%
per annum until the Exchange Offer is consummated. Upon consummation of the
Exchange Offer, holders of Old Capital Securities will not be entitled to any
increase in the Distribution rate thereon or any further registration rights
under the Registration Rights Agreement. The New Capital Securities will not be
entitled to any such increase in the Distribution rate thereon. See "Description
of Old Capital Securities."

TRADING CHARACTERISTICS OF THE CAPITAL SECURITIES

         The Capital Securities may trade at a price that does not fully reflect
the value of accrued but unpaid interest with respect to the underlying Junior
Subordinated Debentures. A holder who uses the accrual method of accounting for
tax purposes (and a cash method holder, if the Junior Subordinated Debentures
are deemed to have been issued with OID) and who disposes of its Capital
Securities between record dates for payments of distributions thereon will be
required to include accrued but unpaid interest on the Junior Subordinated
Debentures through the date of disposition in income as ordinary income (i.e.,
interest or, possibly, OID), and to add such amount to its adjusted tax basis in
its share of the underlying Junior Subordinated Debentures deemed disposed of.
To the extent the selling price is less than the holder's adjusted tax basis
(which will include all accrued but unpaid interest), a holder 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.
See "Certain Federal Income Tax Considerations -- Interest Income and Original
Issue Discount" and "-- Sales of Capital Securities."

ABSENCE OF PUBLIC MARKET

         The Old Capital Securities have not been registered under the
Securities Act and will continue to be subject to restrictions on
transferability under the Securities Act and applicable state securities laws if
they are not exchanged for New Capital Securities. Although the New Capital
Securities generally may be resold or otherwise transferred by the holders (who
are not Affiliates of the Corporation or the Trust) without compliance with the
registration requirements under the Securities Act, they will constitute a new
issue of securities with no established trading market. Capital Securities may
be transferred by the holders thereof only in blocks having a Liquidation Amount
of not less than $100,000 (100 Capital Securities). The Corporation and the
Trust were advised by the Initial Purchasers in connection with the offering of
the Old Capital Securities that the Initial Purchasers intend to make a market
in the Old Capital Securities. However, neither Initial Purchaser is obligated
to do so and any market-making activity with respect to the New Capital
Securities may be discontinued at any time without notice. In addition, such
market-making activity will be subject to the limits imposed by the Securities
Act and the Exchange Act and may be limited during the Exchange Offer.
Accordingly, no assurance can be given that an active public or other market
will develop for the New Capital Securities or the Old Capital Securities or as
to the liquidity of or the trading market for the New Capital Securities or the
Old Capital


                                       23
<PAGE>   25
Securities. If an active public market does not develop, the market price and
liquidity of the New Capital Securities may be adversely affected.

         If a public trading market develops for the New Capital Securities,
future trading prices will depend on many factors, including, among other
things, prevailing interest rates, the Corporation's results of operations and
the market for similar securities. Depending on prevailing interest rates, the
market for similar securities and other factors, including the financial
condition of the Corporation, the New Capital Securities may trade at a
discount.

         Notwithstanding the registration of the New Capital Securities in the
Exchange Offer, holders who are Affiliates of the Corporation or the Trust may
publicly offer for sale or resell the New Capital Securities only in compliance
with the provisions of Rule 144 under the Securities Act.

         Each Participating Broker-Dealer that receives New Capital Securities
for its own account in exchange for Old Capital Securities must acknowledge that
it will deliver a prospectus in connection with any resale of such New Capital
Securities. See "Plan of Distribution."

EXCHANGE OFFER PROCEDURES

         Issuance of the New Capital Securities in exchange for Old Capital
Securities pursuant to the Exchange Offer will be made only after a timely
receipt by the Trust of such Old Capital Securities, a properly completed and
duly executed Letter of Transmittal or Agent's Message in lieu thereof and all
other required documents. Therefore, holders of the Old Capital Securities
desiring to tender such Old Capital Securities in exchange for New Capital
Securities should allow sufficient time to ensure timely delivery. None of the
Corporation, the Trust or the Exchange Agent is under any duty to give
notification of defects or irregularities with respect to the tenders of Old
Capital Securities for exchange.

                                    THE TRUST

         The Trust is a statutory business trust created under Delaware law
pursuant to (i) a Declaration of Trust, dated as of January 24, 1997, executed
by the Corporation, as Sponsor, the Delaware Trustee and the Administrative
Trustee named therein (the "Initial Declaration"), and (ii) the filing of a
certificate of trust with the Secretary of State of the State of Delaware on
January 27, 1997. The Initial Declaration was replaced by an amended and
restated declaration of trust executed as of the Issue Date by the Corporation,
as Sponsor, and the Issuer Trustees (as defined herein) (the "Declaration"). The
Trust exists for the exclusive purposes of (i) issuing and selling the Trust
Securities, which represent undivided beneficial interests in the assets of the
Trust, (ii) investing the gross proceeds from the sale of the Trust Securities
in the Junior Subordinated Debentures and (iii) engaging in only those other
activities necessary, advisable or incidental thereto. Accordingly, the Junior
Subordinated Debentures will be the sole assets of the Trust and payments under
the Junior Subordinated Debentures will be the sole revenues of the Trust. All
of the Common Securities are owned directly by the Corporation. The Common
Securities rank pari passu, and payments will be made thereon pro rata, with the
Capital Securities, except that upon the occurrence and during the continuance
of an Event of Default, the rights of the Corporation as holder of the Common
Securities to payments in respect of Distributions and payments upon
liquidation, redemption or otherwise will be subordinated and rank junior to the
rights of the holders of the Capital Securities. See "Description of New
Securities - Description of Capital Securities -- Subordination of Common
Securities." The Corporation acquired Common Securities in a Liquidation Amount
equal to 3% of the total capital of the Trust. The Trust has a term of 31 years,
but may terminate earlier as provided in the Declaration. The Trust's business
and affairs are conducted by trustees (the "Issuer Trustees") appointed by the
Corporation as the direct holder of the Common Securities. The Issuer Trustees
are The Bank of New York as the Property Trustee (the "Property Trustee"), The
Bank of New York


                                       24
<PAGE>   26
(Delaware) as the Delaware Trustee (the "Delaware Trustee") and three individual
trustees (the "Administrative Trustees"). The Bank of New York, as Property
Trustee, acts as sole indenture trustee under the Declaration. The Bank of New
York also acts as indenture trustee under the Guarantee and the Indenture. See
"Description of New Securities - Description of Guarantee" and "- Description of
Junior Subordinated Debentures." The holder of the Common Securities or, if an
Event of Default under the Declaration has occurred and is continuing, the
holders of not less than a majority in Liquidation Amount of the Capital
Securities, will be entitled to appoint, remove or replace the Property Trustee
and/or the Delaware Trustee. In no event will the holders of the Capital
Securities have the right to vote to appoint, remove or replace the
Administrative Trustees; such voting rights will be vested exclusively in the
holder of the Common Securities. The duties and obligations of each Issuer
Trustee are governed by the Declaration. The Corporation will pay directly all
fees, expenses, debts and obligations (other than the Trust Securities) related
to the Exchange Offer, except as provided herein, and will pay, directly or
indirectly, all ongoing costs, expenses and liabilities of the Trust.

</TABLE>


(1) Balance sheet data reflects the acquisition of Family Bancorp on December 6,
1996, and operations data reflects the operations of Family Bancorp from the
date of acquisition. This transaction was accounted for under the purchase
method of accounting.

(2) All securities were classified as available for sale at December 31, 1996
and 1995.

(3)  Does not include loans held for sale.

(4) Nonperforming assets consist of nonperforming loans, other real estate owned
and repossessions, net of related reserves where appropriate. Nonperforming
loans consist of non-accrual loans, accruing loans 90 days or more overdue and
troubled debt restructurings.

(5) Peoples Heritage's results of operations for 1993 reflect the elimination of
the valuation allowance relating to deferred income tax assets of $6.5 million.

(6) Reflects the adoption of Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes," effective January 1, 1992.

(7) With the exception of end of period ratios, all ratios are based on average
daily balances during the indicated periods.

(8) Excluding a $1.85 million nonrecurring pre-tax charge for the
recapitalization of the Savings Association Insurance Fund in 1996 and pre-tax
merger-related expenses of $5.1 million and $5.0 million in 1996 and 1995,
respectively, and the tax effects of those amounts, return on average assets was
1.32% and 1.25% in 1996 and 1995, respectively, and return on average equity was
15.71% and 14.66% during the same respective periods.

(9) Average equity excludes the effect of unrealized gains or losses on
securities available for sale.

(10) Interest rate spread represents the difference between the weighted average
yield on interest-earning assets and the weighted average cost of
interest-bearing liabilities (which do not include non-interest bearing demand
accounts), and net interest margin represents net interest income as a percent
of average interest-earning assets, in each case calculated on a fully-taxable
equivalent basis.

(11) For purposes of computing the ratios of earnings to fixed charges, earnings
represent net income (loss) before extraordinary items and cumulative effect of
changes in accounting principle plus applicable income taxes and fixed charges.
Fixed charges, excluding interest on deposits, include gross interest expense
(other than on deposits) and the proportion deemed representative of the
interest factor of rent expense. Fixed charges, including gross interest on
deposits, include all interest expense and the proportion deemed representative
of the interest factor of rent expense. During 1992, earnings were insufficient
to cover fixed charges by $5.4 million in each case.

                                 USE OF PROCEEDS

         Neither the Corporation nor the Trust will receive any cash proceeds
from the issuance of the New Capital Securities offered hereby. The Old Capital
Securities surrendered in exchange for the New Capital Securities will be
retired and cancelled.

         The proceeds to the Trust from the offering of the Old Capital
Securities was $100,000,000 (before giving effect to approximately $1,750,000 of
expenses of the offering payable by the Corporation). All of the proceeds from
the sale of Old Capital Securities was invested by the Trust in the Junior
Subordinated Debentures. The net proceeds were added by the Corporation to its
general corporate funds and have been and will be used for general corporate
purposes, including the making of advances to its banking subsidiaries and, from
time to time, the purchase, in the open market or in privately-negotiated
transactions, of outstanding shares of common stock of the Corporation, as well
as in connection with one or more future acquisitions by the Corporation.
Pending such application by the Corporation, the net proceeds may be temporarily
invested in short-term investments.

         The Corporation is required by the Federal Reserve to maintain certain
levels of capital for regulatory purposes. The Capital Securities qualify as
Tier 1 capital under the capital guidelines of the Federal Reserve, which
provide that no more than 25% of the Corporation's Tier 1 capital may be
comprised of Capital Securities and other capital securities and cumulative
preferred stock of the Corporation.

(1)      As described herein, the sole assets of the Trust, which is a
         subsidiary of the Corporation, are $103,093,000 aggregate principal
         amount of Junior Subordinated Debentures (including the amounts
         attributable to the issuance of the Common Securities of the Trust),
         which accrue interest at the rate of 9.06% per annum and will mature on
         February 1, 2027. The Corporation owns all of the Common Securities
         issued by the Trust. It is anticipated that the Trust will not be
         subject to the reporting requirements under the Exchange Act. See
         "Accounting Treatment."

(2)      Tier 1 capital consists of common equity, retained earnings and a
         limited amount of qualifying perpetual preferred stock (including the
         Capital Securities), less certain intangibles.

(3)      Total capital consists of Tier 1 capital and subordinated debt,
         qualifying preferred stock and a limited amount of the allowance for
         loan and lease losses. At least half of a bank holding company's total
         capital is to be composed of Tier 1 capital.

(4)      The leverage ratio is defined as the ratio of Tier 1 capital divided by
         adjusted average quarterly assets.

(5)      Federal Reserve guidelines provide for a minimum leverage ratio of
         three percent for bank holding companies that meet certain specified
         criteria, including that they have the highest regulatory rating. All
         other bank holding companies will be required to maintain a leverage
         ratio of three percent plus an additional amount 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.


                              ACCOUNTING TREATMENT

         For financial reporting purposes, the Trust will be treated as a
subsidiary of the Corporation and, accordingly, the accounts of the Trust will
be included in the consolidated financial statements of the Corporation. The
Capital Securities will be presented as a separate line item in the consolidated
balance sheets of the Corporation, entitled "Corporation-obligated, mandatorily
redeemable securities of subsidiary trust holding solely junior subordinated
debentures of the Corporation," and appropriate disclosures about the Capital
Securities, the Guarantee and the Junior Subordinated Debentures will be
included in the notes to the consolidated financial statements. For financial
reporting purposes, the Corporation will record Distributions payable on the
Capital Securities as an expense in the consolidated statements of income.

         The Corporation has agreed that future financial reports of the
Corporation will: (i) present the Capital Securities issued by the Trust on the
consolidated balance sheet as a separate line item entitled
"Corporation obligated, mandatorily redeemable securities of subsidiary trust
holding solely junior subordinated debentures of the Corporation," which will be
classified similar to minority interests; (ii) include in a note to the
Corporation's consolidated financial statements disclosure that the sole assets
of the Trust are the Junior Subordinated Debentures (specifying the principal
amount, interest rate and maturity date of the Junior Subordinated Debentures)
and whether Staff Accounting Bulletin 53 treatment is sought; and (iii) include,
in an audited note to the consolidated financial statements, disclosure that (a)
the Trust is wholly-owned; (b) the sole assets of the Trust are the Junior
Subordinated Debentures; and (c) the obligations of the Corporation under the
applicable documents, in the aggregate, constitute a full and unconditional
guarantee by the Corporation of the Trust's obligations under the Capital
Securities.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

         In connection with the sale of the Old Capital Securities, the
Corporation and the Trust entered into the Registration Rights Agreement with
the Initial Purchasers, pursuant to which the Corporation and the Trust agreed
to file and to use their reasonable best efforts to cause to be declared
effective by the Commission a registration statement with respect to the
exchange of the Old Capital Securities for capital securities with terms
identical in all material respects to the terms of the Old Capital Securities. A
copy of the Registration Rights Agreement has been filed as an Exhibit to the
Registration Statement of which this Prospectus is a part.

         The Exchange Offer is being made to satisfy the contractual obligations
of the Corporation and the Trust under the Registration Rights Agreement. The
form and terms of the New Capital Securities are the same as the form and terms
of the Old Capital Securities except that the New Capital Securities (i) have
been registered under the Securities Act and therefore will not be subject to
certain restrictions on transfer under federal and state securities laws and
(ii) will not provide for any increase in the Distribution rate thereon. In that
regard, the Old Capital Securities provide, among other things, that, if a
registration statement relating to the Exchange Offer has not been filed by June
30, 1997 and declared effective by July 30, 1997, the Distribution rate borne by
the Old Capital Securities, commencing on July 31, 1997 will increase by 0.25%
per annum until the Exchange Offer is consummated. Upon consummation of the
Exchange Offer, holders of Old Capital Securities will not be entitled to any
increase in the Distribution rate thereon or any further registration rights
under the Registration Rights Agreement. See "Risk Factors--Consequences of a
Failure to Exchange Old Capital Securities" and "Description of Old Capital
Securities."

         The Exchange Offer is not being made to, nor will the Trust accept
tenders for exchange from, holders of Old Capital Securities in any jurisdiction
in which the Exchange Offer or the acceptance thereof would not be in compliance
with the securities or blue sky laws of such jurisdiction.

         Unless the context requires otherwise, the term "holder" with respect
to the Exchange Offer means any person in whose name the Old Capital Securities
are registered on the books of the Trust or any other person who has obtained a
properly completed bond power from the registered holder, or any participant in
the DTC system whose name appears on a security position listing as the holder
of such Old Capital Securities and who desires to deliver such Old Capital
Securities by book-entry transfer at DTC.

         Pursuant to the Exchange Offer, the Corporation will exchange as soon
as practicable after the date hereof, the Old Guarantee for the New Guarantee
and the Old Junior Subordinated Debentures, in an amount corresponding to the
Old Capital Securities accepted for exchange, for a like aggregate principal
amount of the New Junior Subordinated Debentures. The New Guarantee and the New
Junior Subordinated Debentures have been registered under the Securities Act.

TERMS OF THE EXCHANGE OFFER

         The Trust hereby offers, upon the terms and subject to the conditions
set forth in this Prospectus and in the accompanying Letter of Transmittal, to
exchange up to $100,000,000 aggregate Liquidation Amount of New Capital
Securities for a like aggregate Liquidation Amount of Old Capital Securities
properly tendered on or prior to the Expiration Date and not properly withdrawn
in accordance with the procedures described below. The Trust will issue,
promptly after the Expiration Date, an aggregate Liquidation Amount of up to
$100,000,000 of New Capital Securities in exchange for a like aggregate
Liquidation Amount of outstanding Old Capital Securities tendered and accepted
in connection with the Exchange Offer. Holders may tender their Old Capital
Securities in whole or in part in a Liquidation Amount of not less than $100,000
(100 Capital Securities) or any integral multiple of $1,000 Liquidation Amount
(one Capital Security) in excess thereof, provided that if any Old

Capital Securities are tendered in exchange for part, the untendered Liquidation
Amount must be $100,000 or any integral multiple of $1,000 in excess thereof.

         The Exchange Offer is not conditioned upon any minimum Liquidation
Amount of Old Capital Securities being tendered. As of the date of this
Prospectus, $100,000,000 aggregate Liquidation Amount of the Old Capital
Securities is outstanding.

         Holders of Old Capital Securities do not have any appraisal or
dissenters' rights in connection with the Exchange Offer. Old Capital Securities
which are not tendered for or are tendered but not accepted in connection with
the Exchange Offer will remain outstanding and be entitled to the benefits of
the Declaration, but will not be entitled to any further registration rights
under the Registration Rights Agreement. See "Risk Factors--Consequences of a
Failure to Exchange Old Capital Securities" and "Description of Old Securities."

         If any tendered Old Capital Securities are not accepted for exchange
because of an invalid tender, the occurrence of certain other events set forth
herein or otherwise, certificates for any such unaccepted Old Capital Securities
will be returned, without expense, to the tendering holder thereof promptly
after the Expiration Date.

         Holders who tender Old Capital Securities in connection with the
Exchange Offer will not be required to pay brokerage commissions or fees or,
subject to the instructions in the Letter of Transmittal, transfer taxes with
respect to the exchange of Old Capital Securities in connection with the
Exchange Offer. The Corporation will pay all charges and expenses, other than
certain applicable taxes described below, in connection with the Exchange Offer.
See "--Fees and Expenses."

         NEITHER THE BOARD OF DIRECTORS OF THE CORPORATION NOR ANY TRUSTEE OF
THE TRUST MAKES ANY RECOMMENDATION TO HOLDERS OF OLD CAPITAL SECURITIES AS TO
WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY PORTION OF THEIR OLD
CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER. IN ADDITION, NO ONE HAS BEEN
AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF OLD CAPITAL SECURITIES
MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFER
AND, IF SO, THE AGGREGATE AMOUNT OF OLD CAPITAL SECURITIES TO TENDER BASED ON
SUCH HOLDERS OWN FINANCIAL POSITION AND REQUIREMENTS.


EXPIRATION, DATE; EXTENSIONS; AMENDMENTS

         The term "Expiration Date" means 5:00 p.m., New York City time, on
__________ ___, 1997 unless the Exchange Offer is extended by the Corporation or
the Trust (in which case the term "Expiration Date" shall mean the latest date
and time to which the Exchange Offer is extended).

         The Corporation and the Trust expressly reserve the right in their sole
and absolute discretion, subject to applicable law, at any time and from time to
time, (i) to delay the acceptance of the Old Capital Securities for exchange,
(ii) to terminate the Exchange Offer (whether or not any Old Capital Securities
have theretofore been accepted for exchange) if the Corporation and the Trust
determine, in their sole and absolute discretion, that any of the events or
conditions referred to under "--Conditions to the Exchange Offer" have occurred
or exist or have not been satisfied, (iii) to extend the Expiration Date of the
Exchange Offer and retain all Old Capital Securities tendered pursuant to the
Exchange Offer, subject, however, to the right of holders of Old Capital
Securities to withdraw their tendered Old Capital Securities as described under
"--Withdrawal Rights," and (iv) to waive any condition or otherwise amend the
terms of the Exchange Offer in any respect. If the Exchange Offer is amended in
a manner determined by the Corporation and the Trust to constitute a material
change, or if the Corporation and the Trust waive a material condition of the
Exchange Offer, the Corporation and the Trust will promptly disclose such
amendment by means of a Prospectus supplement that will be distributed to


                                       32
<PAGE>   34
the registered holders of the Old Capital Securities, and the Corporation and
the Trust will extend the Exchange Offer to the extent required by Rule 14e-1
under the Exchange Act.

         Any such delay in acceptance, extension, termination or amendment will
be followed promptly by oral or written notice thereof to the Exchange Agent and
by making a public announcement thereof, and such announcement in the case of an
extension will be made no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. Without limiting
the manner in which the Corporation and the Trust may choose to make any public
announcement and subject to applicable law, the Corporation and the Trust shall
have no obligation to publish, advertise or otherwise communicate any such
public announcement other than by issuing a release to an appropriate news
agency.

ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF NEW CAPITAL SECURITIES

         Upon the terms and subject to the conditions of the Exchange Offer, the
Trust will exchange, and will issue to the Exchange Agent, New Capital
Securities for Old Capital Securities validly tendered and not withdrawn
promptly after the Expiration Date.

         In all cases, delivery of New Capital Securities in exchange for Old
Capital Securities tendered and accepted for exchange pursuant to the Exchange
Offer will be made only after timely receipt by the Exchange Agent of (i) Old
Capital Securities or a book-entry confirmation of a book-entry transfer of Old
Capital Securities into the Exchange Agent's account at DTC, including an
Agent's Message if the tendering holder has not delivered a Letter of
Transmittal, (ii) the Letter of Transmittal (or facsimile thereof), properly
completed and duly executed, with any required signature guarantees, or (in the
case of a book-entry transfer) an Agent's Message in lieu of the Letter of
Transmittal, and (iii) any other documents required by the Letter of
Transmittal.

         The term "book-entry confirmation" means a timely confirmation of a
book-entry transfer of Old Capital Securities into the Exchange Agent's account
at DTC. The term "Agent's Message" means a message, transmitted by DTC to and
received by the Exchange Agent and forming a part of a book-entry confirmation,
which states that DTC has received an express acknowledgement from the tendering
participant, which acknowledgment states that such participant has received and
agrees to be bound by the Letter of Transmittal and that the Trust and the
Corporation may enforce such Letter of Transmittal against such participant.

         Subject to the terms and conditions of the Exchange Offer, the
Corporation and the Trust will be deemed to have accepted for exchange, and
thereby exchanged, Old Capital Securities validly tendered and not withdrawn as,
if and when the Trust gives oral or written notice to the Exchange Agent of the
Corporation's and the Trust's acceptance of such Old Capital Securities for
exchange pursuant to the Exchange Offer. The Exchange Agent will act as agent
for the Trust for the purpose of receiving tenders of Old Capital Securities,
Letters of Transmittal and related documents, and as agent for tendering holders
for the purpose of receiving Old Capital Securities, Letters of Transmittal and
related documents and transmitting New Capital Securities to validly tendering
holders. Such exchange will be made promptly after the Expiration Date. If, for
any reason whatsoever, acceptance for exchange or the exchange of any Old
Capital Securities tendered pursuant to the Exchange Offer is delayed (whether
before or after the Trust's acceptance for exchange of Old Capital Securities)
or the Corporation and the Trust extend the Exchange Offer or are unable to
accept for exchange or exchange Old Capital Securities tendered pursuant to the
Exchange Offer, then, without prejudice to the Corporation's and the Trust's
rights set forth herein, the Exchange Agent may, nevertheless, on behalf of the
Corporation and the Trust and subject to Rule 14e-1(c) under the Exchange Act,
retain tendered Old Capital Securities and such Old Capital Securities may not
be withdrawn except to the extent tendering holders are entitled to withdrawal
rights as described under "--Withdrawal Rights."

         Pursuant to the Letter of Transmittal or Agent's Message in lieu
thereof, a holder of Old Capital Securities will warrant and agree in the Letter
of Transmittal that it has full power and authority to tender,


                                       33
<PAGE>   35
exchange, sell, assign and transfer Old Capital Securities, that the Trust will
acquire good, marketable and unencumbered title to the tendered Old Capital
Securities, free and clear of all liens, restrictions, charges and encumbrances,
and the Old Capital Securities tendered for exchange are not subject to any
adverse claims or proxies. The holder also will warrant and agree that it will,
upon request, execute and deliver any additional documents deemed by the
Corporation, the Trust or the Exchange Agent to be necessary or desirable to
complete the exchange, sale, assignment and transfer of the Old Capital
Securities tendered pursuant to the Exchange Offer.

PROCEDURES FOR TENDERING OLD CAPITAL SECURITIES

         VALID TENDER. Except as set forth below, in order for Old Capital
Securities to be validly tendered pursuant to the Exchange Offer, a properly
completed and duly executed Letter of Transmittal (or facsimile thereof), with
any required signature guarantees, or (in the case of a book-entry transfer) an
Agent's Message in lieu of a Letter of Transmittal, and any other required
documents, must be received by the Exchange Agent at one of its addresses set
forth under "--Exchange Agent," and (i) tendered Old Capital Securities must be
received by the Exchange Agent, or (ii) such Old Capital Securities must be
tendered pursuant to the procedures for book-entry transfer set forth below and
a book-entry confirmation, including an Agent's Message if the tendering holder
has not delivered a Letter of Transmittal, must be received by the Exchange
Agent, in each case on or prior to the Expiration Date, or (iii) the guaranteed
delivery procedures set forth below must be complied with.

         If less than all of the Old Capital Securities are tendered, a
tendering holder should fill in the amount of Old Capital Securities being
tendered in the appropriate box on the Letter of Transmittal or so indicate in
an Agent's Message in lieu of the Letter of Transmittal and the untendered
Liquidation Amount must be $100,000 or any integral multiple of $1,000 in excess
thereof. The entire amount of Old Capital Securities delivered to the Exchange
Agent will be deemed to have been tendered unless otherwise indicated.

         THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING
HOLDER, AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
EXCHANGE AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL, RETURN-RECEIPT
REQUESTED, PROPERLY INSURED, OR AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN
ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

         BOOK-ENTRY TRANSFER. The Exchange Agent will establish an account with
respect to the Old Capital Securities at DTC for purposes of the Exchange Offer
within two business days after the date of this Prospectus. Any financial
institution that is a participant in DTC's book-entry transfer facility system
may make a book-entry delivery of the Old Capital Securities by causing DTC to
transfer such Old Capital Securities into the Exchange Agent's account at DTC in
accordance with DTC's procedures for transfers. However, although delivery of
Old Capital Securities may be effected through book-entry transfer into the
Exchange Agent's account at DTC, the Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, with any required signature
guarantees, or an Agent's Message in lieu of the Letter of Transmittal, and any
other required documents, must in any case be delivered to and received by the
Exchange Agent at its address set forth under "--Exchange Agent" on or prior to
the Expiration Date, or the guaranteed delivery procedure set forth below must
be complied with.

         DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S PROCEDURES DOES
NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

         SIGNATURE GUARANTEES. Certificates for the Old Capital Securities need
not be endorsed and signature guarantees on the Letter of Transmittal are
unnecessary unless (i) a certificate for the Old Capital Securities is


                                       34
<PAGE>   36
registered in a name other than that of the person surrendering the certificate
or (ii) such holder completes the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" in the Letter of Transmittal. In the case of
(i) or (ii) above, such certificates for Old Capital Securities must be duly
endorsed or accompanied by a properly executed bond power, with the endorsement
or signature on the bond power and on the Letter of Transmittal guaranteed by a
firm or other entity identified in Rule 17Ad-15 under the Exchange Act as an
"eligible guarantor institution," including (as such terms are defined therein):
(i) a bank; (ii) a broker, dealer, municipal securities broker or dealer or
government securities broker or dealer; (iii) a credit union; (iv) a national
securities exchange, registered securities association or clearing agency; or
(v) a savings association that is a participant in a Securities Transfer
Association (an "Eligible Institution"), unless surrendered on behalf of such
Eligible Institution. See Instruction 1 to the Letter of Transmittal.

         GUARANTEED DELIVERY. If a holder desires to tender Old Capital
Securities pursuant to the Exchange Offer and the certificates for such Old
Capital Securities are not immediately available or time will not permit all
required documents to reach the Exchange Agent on or prior to the Expiration
Date, or the procedure for book-entry transfer cannot be completed on a timely
basis, such Old Capital Securities may nevertheless be tendered, provided that
all of the following guaranteed delivery procedures are complied with:

         (i) such tenders are made by or through an Eligible Institution;

         (ii) a properly completed and duly executed Notice of Guaranteed
Delivery, substantially in the form accompanying the Letter of Transmittal, is
received by the Exchange Agent, as provided below, on or prior to the Expiration
Date; and

         (iii) the certificates (or a book-entry confirmation) representing all
tendered Old Capital Securities, in proper form for transfer, together with a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), or Agent's Message in lieu thereof, with any required signature
guarantees and any other documents required by the Letter of Transmittal, are
received by the Exchange Agent within three New York Stock Exchange trading days
after the date of execution of such Notice of Guaranteed Delivery.

         The Notice of Guaranteed Delivery may be delivered by hand, or
transmitted by facsimile or mail to the Exchange Agent and must include a
guarantee by an Eligible Institution in the form set forth in such notice.

         Notwithstanding any other provision hereof, the delivery of New Capital
Securities in exchange for Old Capital Securities tendered and accepted for
exchange pursuant to the Exchange Offer will in all cases be made only after
timely receipt by the Exchange Agent of Old Capital Securities, or of a
book-entry confirmation with respect to such Old Capital Securities, and a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), or Agent's Message in lieu thereof, together with any required
signature guarantees and any other documents required by the Letter of
Transmittal. Accordingly, the delivery of New Capital Securities might not be
made to all tendering holders at the same time, and will depend upon when Old
Capital Securities, book-entry confirmations with respect to Old Capital
Securities and other required documents are received by the Exchange Agent.

         The Corporation's and the Trust's acceptance for exchange of Old
Capital Securities tendered pursuant to any of the procedures described above
will constitute a binding agreement between the tendering holder, the
Corporation and the Trust upon the terms and subject to the conditions of the
Exchange Offer.

         DETERMINATION OF VALIDITY. All questions as to the form of documents,
validity, eligibility (including time of receipt) and acceptance for exchange of
any tendered Old Capital Securities will be determined by the Corporation and
the Trust, in their sole discretion, whose determination shall be final and
binding on all parties. The Corporation and the Trust reserve the absolute
right, in their sole and absolute discretion, to reject any and


                                       35
<PAGE>   37
all tenders determined by them not to be in proper form or the acceptance of
which, or exchange for, may, in the opinion of counsel to the Corporation and
the Trust, be unlawful. The Corporation and the Trust also reserve the absolute
right, subject to applicable law, to waive any of the conditions of the Exchange
Offer as set forth under "--Conditions to the Exchange Offer" or any condition
or irregularity in any tender of Old Capital Securities of any particular holder
whether or not similar conditions or irregularities are waived in the case of
other holders.

         The interpretation by the Corporation and the Trust of the terms and
conditions of the Exchange Offer (including the Letter of Transmittal and the
instructions thereto) will be final and binding. No tender of Old Capital
Securities will be deemed to have been validly made until all irregularities
with respect to such tender have been cured or waived. None of the Corporation,
the Trust, any affiliates or assigns of the Corporation or the Trust, the
Exchange Agent or any other person shall be under any duty to give any
notification of any irregularities in tenders or incur any liability for failure
to give any such notification.

         If any Letter of Transmittal, endorsement, bond power, power of
attorney or any other document required by the Letter of Transmittal is signed
by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and unless waived by the
Corporation and the Trust, proper evidence satisfactory to the Corporation and
the Trust, in their sole discretion, of such person's authority to so act must
be submitted.

         A beneficial owner of Old Capital Securities that are held by or
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee or custodian is urged to contact such entity promptly if such
beneficial holder wishes to participate in the Exchange Offer.

RESALES OF NEW CAPITAL SECURITIES

         The Trust is making the Exchange Offer for the New Capital Securities
in reliance on the position of the staff of the Division of Corporation Finance
of the Commission as set forth in certain interpretive letters addressed to
third parties in other transactions. However, neither the Corporation nor the
Trust sought its own interpretive letter and there can be no assurance that the
staff of the Division of Corporation Finance of the Commission would make a
similar determination with respect to the Exchange Offer as it has in such
interpretive letters to third parties. Based on these interpretations by the
staff of the Division of Corporation Finance of the Commission, and subject to
the two immediately following sentences, the Corporation and the Trust believe
that New Capital Securities issued pursuant to this Exchange Offer in exchange
for Old Capital Securities may be offered for resale, resold and otherwise
transferred by a holder thereof (other than a holder who is a broker-dealer)
without further compliance with the registration and prospectus delivery
requirements of the Securities Act, provided that such New Capital Securities
are acquired in the ordinary course of such holder's business and that such
holder is not participating, and has no arrangement or understanding with any
person to participate, in a distribution (within the meaning of the Securities
Act) of such New Capital Securities. However, any holder of Old Capital
Securities who is an Affiliate of the Corporation or the Trust or who intends to
participate in the Exchange Offer for the purpose of distributing New Capital
Securities, or any broker-dealer who purchased Old Capital Securities from the
Trust to resell pursuant to Rule 144A or any other available exemption under the
Securities Act (i) will not be able to rely on the interpretations of the staff
of the Division of Corporation Finance of the Commission set forth in the
above-mentioned interpretive letters, (ii) will not be permitted or entitled to
tender such Old Capital Securities in the Exchange Offer and (iii) must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any sale or other transfer of such Old Capital Securities,
unless such sale is made pursuant to an exemption from such requirements. In
addition, as described below, Participating Broker-Dealers must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resales of New Capital Securities.


                                       36
<PAGE>   38
         Each holder of Old Capital Securities who wishes to exchange Old
Capital Securities for New Capital Securities in the Exchange Offer will be
required to represent that (i) it is not an Affiliate of the Corporation or the
Trust, (ii) any New Capital Securities to be received by it are being acquired
in the ordinary course of its business, (iii) it has no arrangement or
understanding with any person to participate in a distribution (within the
meaning of the Securities Act) of such New Capital Securities and (iv) if such
holder is not a broker-dealer, such holder is not engaged in, and does not
intend to engage in, a distribution (within the meaning of the Securities Act)
of such New Capital Securities. The Letter of Transmittal contains the foregoing
representations. In addition, the Corporation and the Trust may require such
holder, as a condition to such holder's eligibility to participate in the
Exchange Offer, to furnish to the Corporation and the Trust (or an agent
thereof) in writing information as to the number of "beneficial owners" (within
the meaning of Rule 13d-3 under the Exchange Act) on behalf of whom such holder
holds the Capital Securities to be exchanged in the Exchange Offer. Each
Participating Broker-Dealer will be deemed to have acknowledged by execution of
the Letter of Transmittal or delivery of an Agent's Message that it acquired the
Old Capital Securities for its own account as the result of market-making
activities or other trading activities and must agree that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such New Capital Securities. The Letter of Transmittal states that by
so acknowledging and by delivering a prospectus, a Participating Broker-Dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. Based on the position taken by the staff of the Division of
Corporation Finance of the Commission in the interpretive letters referred to
above, the Corporation and the Trust believe that Participating Broker-Dealers
who acquired Old Capital Securities for their own accounts as a result of
market-making activities or other trading activities may fulfill their
prospectus delivery requirements with respect to the New Capital Securities
received upon exchange of such Old Capital Securities (other than Old Capital
Securities which represent an unsold allotment from the original sale of the Old
Capital Securities) with a prospectus meeting the requirements of the Securities
Act, which may be the prospectus prepared for an exchange offer so long as it
contains a description of the plan of distribution with respect to the resale of
such New Capital Securities. Accordingly, this Prospectus, as it may be amended
or supplemented from time to time, may be used by a Participating Broker-Dealer
during the period referred to below in connection with resales of New Capital
Securities received in exchange for Old Capital Securities where such Old
Capital Securities were acquired by such Participating Broker-Dealer for its own
account as a result of market-making or other trading activities. Subject to
certain provisions set forth in the Registration Rights Agreement, the
Corporation and the Trust have agreed that this Prospectus, as it may be amended
or supplemented from time to time, may be used by a Participating Broker-Dealer
in connection with resales of such New Capital Securities for a period ending
90-days after the Expiration Date (subject to extension under certain limited
circumstances described below) or, if earlier, when all such New Capital
Securities have been disposed of by such Participating Broker-Dealer. See "Plan
of Distribution." However, a Participating Broker-Dealer who intends to use this
Prospectus in connection with the resale of New Capital Securities received in
exchange for Old Capital Securities pursuant to the Exchange Offer must notify
the Corporation or the Trust, or cause the Corporation or the Trust to be
notified, on or prior to the Expiration Date, that it is a Participating
Broker-Dealer. Such notice may be given in the space provided for that purpose
in the Letter of Transmittal or may be delivered to the Exchange Agent at one of
the addresses set forth herein under "--Exchange Agent." Any person, including
any Participating Broker-Dealer, who is an Affiliate of the Corporation or the
Trust may not rely on such interpretive letters and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction.

         In that regard, each Participating Broker-Dealer who surrenders Old
Capital Securities pursuant to the Exchange Offer will be deemed to have agreed,
by execution of the Letter of Transmittal or delivery of an Agent's Message in
lieu thereof, that, upon receipt of notice from the Corporation or the Trust of
the occurrence of any event or the discovery of any fact which makes any
statement contained or incorporated by reference in this Prospectus untrue in
any material respect or which causes this Prospectus to omit to state a material
fact necessary in order to make the statements contained or incorporated by
reference herein, in light of the circumstances under which they were made, not
misleading or of the occurrence of certain other events specified in the
Registration Rights Agreement, such Participating Broker-Dealer will suspend the
sale of New Capital


                                       37
<PAGE>   39
Securities (or the New Guarantee or the New Junior Subordinated Debentures, as
applicable) pursuant to this Prospectus until the Corporation or the Trust has
amended or supplemented this Prospectus to correct such misstatement or omission
and has furnished copies of the amended or supplemented Prospectus to such
Participating Broker-Dealer or the Corporation or the Trust has given notice
that the sale of the New Capital Securities (or the New Guarantee or the New
Junior Subordinated Debentures, as applicable) may be resumed, as the case may
be. If the Corporation or the Trust gives such notice to suspend the sale of the
New Capital Securities (or the New Guarantee or the New Junior Subordinated
Debentures, as applicable), it shall extend the 90-day period referred to above
during which Participating Broker-Dealers are entitled to use this Prospectus in
connection with the resale of New Capital Securities by the number of days
during the period from and including the date of the giving of such notice to
and including the date when Participating Broker-Dealers shall have received
copies of the amended or supplemented Prospectus necessary to permit resales of
the New Capital Securities or to and including the date on which the Corporation
or the Trust has given notice that the sale of New Capital Securities (or the
New Guarantee or the New Junior Subordinated Debentures, as applicable) may be
resumed, as the case may be.

WITHDRAWAL RIGHTS

         Except as otherwise provided herein, tenders of Old Capital Securities
may be withdrawn at any time on or prior to the Expiration Date.

         In order for a withdrawal to be effective a written or facsimile
transmission of such notice of withdrawal must be timely received by the
Exchange Agent at one of its addresses set forth under "--Exchange Agent" on or
prior to the Expiration Date. Any such notice of withdrawal must specify the
name of the person who tendered the Old Capital Securities to be withdrawn, the
aggregate principal amount of Old Capital Securities to be withdrawn, and (if
certificates for such Old Capital Securities have been tendered) the name of the
registered holder of the Old Capital Securities as set forth on the Old Capital
Securities, if different from that of the person who tendered such Old Capital
Securities. If Old Capital Securities have been delivered or otherwise
identified to the Exchange Agent, then prior to the physical release of such Old
Capital Securities, the tendering holder must submit the certificate numbers
shown on the particular Old Capital Securities to be withdrawn and the signature
on the notice of withdrawal must be guaranteed by an Eligible Institution,
except in the case of Old Capital Securities tendered for the account of an
Eligible Institution. If Old Capital Securities have been tendered pursuant to
the procedures for book-entry transfer set forth in "--Procedures for Tendering
Old Capital Securities," the notice of withdrawal must specify the name and
number of the account at DTC to be credited with the withdrawal of Old Capital
Securities, in which case a notice of withdrawal will be effective if delivered
to the Exchange Agent by written or facsimile transmission. Withdrawals of
tenders of Old Capital Securities may not be rescinded. Old Capital Securities
properly withdrawn will not be deemed validly tendered for purposes of the
Exchange Offer, but may be retendered at any subsequent time on or prior to the
Expiration Date by following any of the procedures described above under
"--Procedures for Tendering Old Capital Securities."

         All questions as to the validity, form and eligibility (including time
of receipt) of such withdrawal notices will be determined by the Corporation and
the Trust, in their sole discretion, whose determination shall be final and
binding on all parties. None of the Corporation, the Trust, any affiliates or
assigns of the Corporation or the Trust, the Exchange Agent or any other person
shall be under any duty to give any notification of any irregularities in any
notice of withdrawal or incur any liability for failure to give any such
notification. Any Old Capital Securities which have been tendered but which are
withdrawn will be returned to the holder thereof promptly after withdrawal.

DISTRIBUTIONS ON NEW CAPITAL SECURITIES

         Holders of Old Capital Securities whose Old Capital Securities are
accepted for exchange will not receive Distributions on such Old Capital
Securities and will be deemed to have waived the right to receive any
Distributions on such Old Capital Securities accumulated from and after January
31, 1997. Accordingly, holders of New Capital Securities as of the record date
for the payment of Distributions on August 1, 1997 will be entitled to receive
Distributions accumulated from and after January 31, 1997.

CONDITIONS TO THE EXCHANGE OFFER

         Notwithstanding any other provisions of the Exchange Offer, or any
extension of the Exchange Offer, the Corporation and the Trust will not be
required to accept for exchange, or to exchange, any Old Capital Securities for
any New Capital Securities, and, as described below, may terminate the Exchange
Offer (whether or not any Old Capital Securities have theretofore been accepted
for exchange) or may waive any conditions to or amend the Exchange Offer, if any
of the following conditions have occurred or exists or have not been satisfied:

         (a) there shall occur a change in the current interpretation by the
staff of the Commission which permits the New Capital Securities issued pursuant
to the Exchange Offer in exchange for Old Capital Securities to be offered for
resale, resold and otherwise transferred by holders thereof (other than
broker-dealers and any such holder which is an Affiliate of the Corporation or
the Trust) without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such New Capital Securities are
acquired in the ordinary course of such holders' business and such holders have
no arrangement or understanding with any person to participate in the
distribution of such New Capital Securities; or

         (b) any law, statute, rule or regulation shall have been adopted or
enacted which, in the judgment of the Corporation or the Trust, would reasonably
be expected to impair its ability to proceed with the Exchange Offer;

         (c) any action or proceeding shall have been instituted or threatened
in any court or by or before any governmental agency or body with respect to the
Exchange Offer which, in the Corporation's and the Trust's judgment, would
reasonably be expected to impair the ability of the Trust or the Corporation to
proceed with the Exchange Offer;

         (d) a banking moratorium shall have been declared by United States
federal or Maine or New York state authorities which, in the Corporation's and
the Trust's judgment, would reasonably be expected to impair the ability of the
Trust or the Corporation to proceed with the Exchange Offer;

         (e) trading on the New York Stock Exchange or generally in the United
States over-the-counter market shall have been suspended by order of the
Commission or any other governmental authority which, in the Corporation's and
the Trust's judgment, would reasonably be expected to impair the ability of the
Issuer or the Corporation to proceed with the Exchange Offer; or

         (f) a stop order shall have been issued by the Commission or any state

FEES AND EXPENSES

         The Corporation has agreed to pay the Exchange Agent reasonable and
customary fees for its services and will reimburse it for its reasonable
out-of-pocket expenses in connection therewith. The Corporation will also pay
brokerage houses and other custodians, nominees and fiduciaries the reasonable
out-of-pocket expenses incurred by them in forwarding copies of this Prospectus
and related documents to the beneficial owners of Old Capital Securities, and in
handling or tendering for their customers.

         Holders who tender their Old Capital Securities for exchange will not
be obligated to pay any transfer taxes in connection therewith. If, however, New
Capital Securities are to be delivered to, or are to be issued in the name of,
any person other than the registered holder of the Old Capital Securities
tendered, or if a transfer tax is imposed for any reason other than the exchange
of Old Capital Securities in connection with the Exchange Offer, then the amount
of any such transfer taxes (whether imposed on the registered holder or any
other persons) will be payable by the tendering holder. If satisfactory evidence
of payment of such taxes or exemption therefrom is not submitted with the Letter
of Transmittal, the amount of such transfer taxes will be billed directly to
such tendering holder.

         Neither the Corporation nor the Trust will make any payment to brokers,
dealers or other nominees soliciting acceptances of the Exchange Offer.

                          DESCRIPTION OF NEW SECURITIES

DESCRIPTION OF CAPITAL SECURITIES

         Pursuant to the terms of the Declaration, the Trust has issued the Old
Capital Securities and the Common Securities and will issue the New Capital
Securities. The New Capital Securities will represent undivided beneficial
interests in the Trust and the holders of the New Capital Securities and the Old
Capital Securities will be entitled to a preference over the Common Securities
in certain circumstances with respect to Distributions and amounts payable on
redemption of the Trust Securities or liquidation of the Trust. See
"--Subordination of Common Securities." The Declaration has been qualified under
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). This
summary of certain provisions of the Capital Securities, the Common Securities
and the Declaration describes the material terms of the Capital Securities but
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Declaration, including the
definitions therein of certain terms.

         GENERAL. The Capital Securities (including the Old Capital Securities
and the New Capital Securities) are limited to $100,000,000 aggregate
Liquidation Amount at any one time outstanding. The Capital Securities rank pari
passu, and payments thereon will be made pro rata, with the Common Securities
except as described under "--Subordination of Common Securities." Legal title to
the Junior Subordinated Debentures is held by the Property Trustee in trust for
the benefit of the holders of the Capital Securities and the holder of the
Common Securities. The Guarantee is a guarantee on a subordinated and junior
basis with respect to the Capital Securities, but does not guarantee payment of
Distributions or amounts payable on redemption of the Capital Securities or on
liquidation of the Trust when the Trust does not have funds on hand legally
available for such payments. See "--Description of Guarantee."

         DISTRIBUTIONS. Distributions on the Capital Securities are cumulative
from January 31, 1997, the date of original issuance of the Old Capital
Securities, and are payable semi-annually in arrears on February 1 and August 1
of each year, commencing August 1, 1997, at the annual rate of 9.06% of the
Liquidation Amount to the holders of the Capital Securities on the relevant
record dates. The record dates are the fifteenth day of the month which proceeds
the month in which the relevant Distribution Date (as defined below) falls. The
amount of Distributions payable for any period will be computed on the basis of
a 360-day year of twelve 30-day months and, for any period of less than one
calendar month, the number of days elapsed in such month. In the event that any
date on which Distributions are payable on the Capital 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), with the same force
and effect as if made on the date such payment was originally payable (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 New York, New York or
Portland, Maine are authorized or required by law or executive order to remain
closed.

         So long as no "Event of Default" (as defined in the Indenture) with
respect to the Junior Subordinated Debentures (a"Debenture Event of Default")
shall have occurred and be continuing, the Corporation has the right under the
Indenture to elect to defer the payment of interest on the Junior Subordinated
Debentures at any time or from time to time for a period not exceeding 10
consecutive semi-annual periods with respect to each Extension Period, provided
that no Extension Period may extend beyond the Stated Maturity Date. As a
consequence of any such election, semi-annual Distributions on the Capital
Securities will be deferred by the Trust during any such Extension Period.
Distributions to which holders of the Capital Securities are entitled during any
such Extension Period will accumulate additional Distributions thereon at the
rate per annum of 9.06% thereof, compounded semi-annually from the relevant
Distribution Date. The term "Distributions," as used herein, shall include any
such additional Distributions.


                                       41
<PAGE>   43
         During any such Extension Period, the Corporation may further extend
such Extension Period, provided that such extension does not cause such
Extension Period to exceed 10 consecutive semi-annual periods or to extend
beyond the Stated Maturity Date. Upon the termination of any such Extension
Period and the payment of all amounts then due, and subject to the foregoing
limitations, the Corporation may elect to begin a new Extension Period. The
Corporation must give the Property Trustee, the Administrative Trustees and the
Debenture Trustee notice of its election of any such Extension Period at least
five Business Days prior to the earlier of (i) the date the Distributions on the
Capital Securities would have been payable except for the election to begin such
Extension Period and (ii) the date the Administrative Trustees are required to
give notice to any securities exchange or automated quotation system or to
holders of the Capital Securities of the record date or the date such
Distributions are payable, but in any event not less than five Business Days
prior to such record date. 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 Extend Interest Payment Period" and
"Certain Federal Income Tax Considerations--Interest Income and Original Issue
Discount."

         During any such Extension Period, the Corporation may not (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
(which includes common and preferred stock), (ii) make any payment of principal
of or premium, if any, or interest on or repay, repurchase or redeem any debt
securities of the Corporation (including Other Debentures) that rank pari passu
with or junior in right of payment 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
(including Other Guarantees) if such guarantee ranks pari passu with or junior
in right of payment to the Junior Subordinated Debentures (other than (a)
dividends or distributions in shares of, or options, warrants or rights to
subscribe for or purchase shares of, common stock of the Corporation, (b) any
declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under the Guarantee, (d) as a result of a reclassification of the
Corporation's capital stock or the exchange or conversion of one class, or
series of the Corporation's capital stock for another class or series of the
Corporation's capital stock, (e) the purchase of fractional interests in shares
of the Corporation's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged
and (f) 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 or any of the Corporation's dividend reinvestment plans).

         The Corporation has no current intention to exercise its option to
defer payments of interest on the Junior Subordinated Debentures by extending
the interest payment period on the Junior Subordinated Debentures.

         The revenue of the Trust available for distribution to holders of
Capital Securities will be limited to payments under the Junior Subordinated
Debentures in which the Trust has invested the proceeds from the issuance and
sale of the Capital Securities. See "--Description of Junior Subordinated
Debentures--General." If the Corporation does not make interest payments on the
Junior Subordinated Debentures, the Property Trustee will not have funds
available to pay Distributions on the Capital Securities. The payment of
Distributions (if and to the extent the Trust has funds on hand legally
available for the payment of such Distributions) is guaranteed by the
Corporation on a limited basis as set forth herein under "--Description of
Guarantee."

         REDEMPTION. Upon repayment on the Stated Maturity Date or redemption in
whole or in part prior to the Stated Maturity Date of the Junior Subordinated
Debentures (other than following the distribution of the Junior Subordinated
Debentures to the holders of the Trust Securities), 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 of a date of redemption (the "Redemption Date"),


                                       42
<PAGE>   44
at the applicable Redemption Price, which shall be equal to (i) in the case of
the repayment of the Junior Subordinated Debentures on the Stated Maturity Date,
the Maturity Redemption Price (equal to the principal of, and accrued interest
on, the Junior Subordinated Debentures), (ii) in the case of the optional
redemption of the Junior Subordinated Debentures upon the occurrence and
continuation of a Special Event, the Special Event Redemption Price (equal to
the Special Event Prepayment Price in respect of the Junior Subordinated
Debentures) and (iii) in the case of the optional redemption of the Junior
Subordinated Debentures other than as contemplated in clause (ii) above, the
Optional Redemption Price (equal to the Optional Prepayment Price
in respect of the Junior Subordinated Debentures). See "--Description of Junior
Subordinated Debentures--Optional Redemption" and "--Special Event Prepayment."
If less than all of the Junior Subordinated Debentures are to be redeemed on a
Redemption Date, then the proceeds of such redemption shall be allocated to the
redemption pro rata of the Capital Securities and the Common Securities.

         "Like Amount" means (i) with respect to a redemption of the Trust
Securities, Trust Securities having a Liquidation Amount equal to the principal
amount of Junior Subordinated Debentures to be paid in accordance with their
terms and (ii) with respect to a distribution of Junior Subordinated Debentures
upon the liquidation of the Trust, Junior Subordinated Debentures having a
principal amount equal to the Liquidation Amount of the Trust Securities of the
holder to whom such Junior Subordinated Debentures are distributed.

         The Corporation has the option to redeem the Junior Subordinated
Debentures, (i) in whole or in part, on or after the Initial Optional Prepayment
Date, at the applicable Optional Prepayment Price and (ii) in whole but not in
part, at any time before the Initial Optional Prepayment Date, upon the
occurrence of a Special Event, at the Special Event Prepayment Price, in each
case subject to receipt of prior approval by the Federal Reserve if then
required under applicable capital guidelines or policies of the Federal Reserve.

         LIQUIDATION OF THE TRUST AND DISTRIBUTION OF JUNIOR SUBORDINATED
DEBENTURES. The Corporation has the right at any time to terminate the Trust
and, after satisfaction of liabilities to creditors of the Trust as required by
applicable law, to cause the Junior Subordinated Debentures to be distributed to
the holders of the Trust Securities in liquidation of the Trust, subject to the
Trust having received an opinion of counsel to the effect that the distribution
will not be taxable to holders of Capital Securities. Such right is subject to
the prior approval of the Federal Reserve if then required under applicable
capital guidelines or policies of the Federal Reserve.

         Pursuant to the Declaration, the Trust shall automatically terminate
upon the first to occur of: (i) certain events of bankruptcy, dissolution or
liquidation of the Corporation or the Trust; (ii) the distribution of a Like
Amount of the Junior Subordinated Debentures to the holders of the Trust
Securities, if the Corporation, as Sponsor, has given written direction to the
Property Trustee to terminate the Trust (which direction is optional and, except
as described above, wholly within the discretion of the Corporation, as
Sponsor); (iii) redemption of all of the Trust Securities in accordance with
their terms; (iv) expiration of the term of the Trust; and (v) the entry of an
order for the dissolution of the Trust by a court of competent jurisdiction.

         If a termination of the Trust occurs as described in clause (ii) of 
the preceding paragraph or otherwise, the Trust shall be liquidated by the 
Administrative Trustees as expeditiously as the Administrative Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to the holders of the
Trust Securities a Like Amount of the Junior Subordinated Debentures, unless
such distribution is determined by the Property Trustee not to be practicable,
in which event such holders will be entitled to receive out of the assets of
the Trust legally available for distribution to holders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, an amount
equal to, in the case of the Capital Securities, the aggregate of the
Liquidation Amounts of the Capital Securities plus accumulated 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 the Trust has insufficient assets on hand legally available to
pay in full the aggregate Liquidation Distribution, then the amounts payable
directly by the Trust


                                       43
<PAGE>   45
on the Capital Securities and the Common Securities shall be paid on a pro rata
basis, except that if a Debenture Event of Default has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities. See "--Subordination of Common Securities."

         After the liquidation date is fixed for any distribution of Junior
Subordinated Debentures to holders of the Trust Securities, (i) the Trust
Securities will no longer be deemed to be outstanding, (ii) DTC or its nominee,
as the record holder of the Capital Securities in book-entry form, will receive
a registered global certificate or certificates representing the Junior
Subordinated Debentures to be delivered upon such distribution and (iii) any
certificates representing Trust Securities not held by DTC or its nominee will
be deemed to represent Junior Subordinated Debentures having a principal amount
equal to the Liquidation Amount of such Trust Securities, and bearing accrued
and unpaid interest in an amount equal to the accumulated and unpaid
Distributions on such Trust Securities until such certificates are presented to
the Property Trustee or its agent for cancellation, whereupon the Corporation
will issue to such holder, and the Debenture Trustee will authenticate, a
certificate representing such Junior Subordinated Debentures.

         There can be no assurance as to the market prices for the Capital
Securities or the Junior Subordinated Debentures that may be distributed in
exchange for the Trust Securities if a termination and liquidation of the Trust
were to occur. Accordingly, the Capital Securities that an investor may
purchase, or the Junior Subordinated Debentures that the investor may receive on
termination and liquidation of the Trust, may trade at a discount to the price
that the investor paid to purchase the Capital Securities offered hereby.

         REDEMPTION PROCEDURES. Trust Securities redeemed on each Redemption
Date shall be redeemed at the applicable Redemption Price with the proceeds from
the contemporaneous repayment or redemption of the Junior Subordinated
Debentures. Any redemption of Trust Securities shall be made and the applicable
Redemption Price shall be payable on the Redemption Date only to the extent that
the Trust has funds legally available for the payment of such applicable
Redemption Price. See also "--Subordination of Common Securities."

         If the Trust gives a notice of redemption in respect of the Capital
Securities, then, by 12:00 noon, New York City time, on the Redemption Date, to
the extent funds are legally available, with respect to the Capital Securities
held by DTC or its nominees, 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 the Capital Securities. See "--Form, Denomination, Book-Entry
Procedures and Transfer." With respect to the Capital Securities held in
certificated form, the Property Trustee, to the extent funds are legally
available, will irrevocably deposit with the paying agent for the Capital
Securities funds sufficient to pay the applicable Redemption Price and will give
such paying agent irrevocable instructions and authority to pay the applicable
Redemption Price to the holders thereof upon surrender of their certificates
evidencing the Capital Securities. See "--Payment and Paying Agency."
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date shall be payable to the holders of such Capital 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 the Capital Securities will
cease, except the right of the holders of the Capital Securities to receive the
applicable Redemption Price, but without interest on such Redemption Price, and
the Capital Securities will cease to be outstanding. In the event that any
Redemption Date of Capital Securities is not a Business Day, then the applicable
Redemption Price payable on such date will be paid on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), in each case with the same force and effect as if made on such
date. In the event that payment of the applicable Redemption Price is improperly
withheld or refused and not paid either by the Trust or by the Corporation
pursuant to the Guarantee as described under "--Description of Guarantee,"
Distributions on Capital Securities will continue to accumulate at the then
applicable rate, from the Redemption Date originally established by the Trust to
the date such applicable Redemption Price is actually


                                       44
<PAGE>   46
paid, in which case the actual payment date will be the Redemption Date for
purposes of calculating the applicable 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 Capital Securities by tender, in the open
market or by private agreement.

         Notice of any redemption will be mailed at least 30 days but not more
than 60 days prior to the Redemption Date to each holder of Trust Securities at
its registered address. Unless the Corporation defaults in payment of the
applicable Prepayment Price on, or in the repayment of, the Junior Subordinated
Debentures, on and after the Redemption Date Distributions will cease to accrue
on the Trust Securities called for redemption.

         SUBORDINATION OF COMMON SECURITIES. Payment of Distributions on, and
the Redemption Price of, the Capital Securities and Common Securities, as
applicable, shall be made pro rata based on the Liquidation Amount of the
Capital 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 applicable
Redemption Price of, the Common Securities, and no other payment on account of
the redemption, liquidation or other acquisition of the Common Securities, shall
be made unless payment in full in cash of all accumulated and unpaid
Distributions on all of the outstanding Capital Securities for all Distribution
periods terminating on or prior thereto, or in the case of payment of Capital
Securities called for redemption on a Redemption Date on or prior thereto, the
full amount of the Redemption Price therefor, 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
Capital Securities then due and payable.

         In the case of any "Event of Default" (as defined in the Declaration)
(an "Event of Default"), the Corporation as holder of the Common Securities will
be deemed to have waived any right to act with respect to such Event of Default
until the effect of such Event of Default shall have been cured, waived or
otherwise eliminated. Until any such Event of Default has been so cured, waived
or otherwise eliminated, the Property Trustee shall act solely on behalf of the
holders of the Capital Securities and not on behalf of the Corporation, as
holder of the Common Securities, and only the holders of the Capital Securities
will have the right to direct the Property Trustee to act on their behalf.

         EVENTS OF DEFAULT; NOTICE. The occurrence of a Debenture Event of
Default (see "Description of Junior Subordinated Debentures--Debenture Events of
Default") constitutes an "Event of Default" under the Declaration.

         Within 10 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 the Capital Securities, the
Administrative Trustees and the Corporation, as Sponsor, unless such Event of
Default shall have been cured or waived. The Corporation, as Sponsor, 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 the Declaration.

         If a Debenture Event of Default has occurred and is continuing, the
Capital Securities shall have a preference over the Common Securities as
described under "--Liquidation of the Trust and Distribution of Junior
Subordinated Debentures" and "--Subordination of Common Securities."


                                       45
<PAGE>   47
         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 Capital Securities. In no event will the holders of the Capital
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 Declaration.

         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 Issuer Trustee shall be a party, or any Person
succeeding to all or substantially all the corporate trust business of such
Issuer Trustee, shall be the successor of such Issuer Trustee under the
Declaration, provided such Person shall be otherwise qualified and eligible.

         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 as an entirety or
substantially as an entirety to any corporation or other Person, except as
described below or as otherwise described under "- Liquidation of the Trust and
Distribution of Junior Subordinated Debentures." The Trust may, at the request
of the Corporation, as Sponsor, with the consent of the Administrative Trustees
but without the consent of the holders of the Capital Securities, merge or
convert with or into, consolidate, amalgamate or be replaced by or convey,
transfer or lease its properties and assets as an entirety or 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 Capital Securities or (b)
substitutes for the Capital Securities other securities having substantially the
same terms as the Capital Securities (the "Successor Securities") so long as the
Successor Securities rank the same as the Capital Securities rank 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 with
respect to the 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
Capital Securities are then listed, if any, (iv) such merger, conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
cause the Capital Securities (including any Successor Securities) to be
downgraded by any nationally-recognized statistical rating organization, (v)
such merger, conversion, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the holders of the Capital Securities (including any Successor
Securities) in any material respect, (vi) such successor entity has a purpose
substantially identical to that of the Trust, (vii) prior to such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, the
Corporation has received an opinion from independent counsel to the Trust
experienced in such matters to the effect that (a) such merger, conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Capital Securities (including any Successor Securities) in any material respect,
and (b) following such merger, conversion, 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
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 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 Trust
Securities, consolidate, amalgamate, merge or convert with or into, or be

assets as an entirety or substantially as an entirety to any other entity or
permit any other entity to consolidate, amalgamate, merge or convert with or
into, or replace it if such consolidation, amalgamation, merger, conversion,
replacement, conveyance, transfer or lease would cause the Trust or the
successor entity not to be classified as a grantor trust for United States
federal income tax purposes.

         VOTING RIGHTS; AMENDMENT OF THE DECLARATION. Except as provided below
and under "--Mergers, Consolidations, Amalgamations or Replacements of the
Trust" and "--Description of Guarantee--Amendments and Assignment" and as
otherwise required by law and the Declaration, the holders of the Capital
Securities will have no voting rights.

         The Declaration may be amended from time to time by the Corporation, as
Sponsor, the Property Trustee and the Administrative Trustees, without the
consent of the holders of the Trust Securities (i) to cure any ambiguity,
correct or supplement any provisions in the Declaration that may be inconsistent
with any other provision, or to make any other provisions with respect to
matters or questions arising under the Declaration, which shall not be
inconsistent with the other provisions of the Declaration, (ii) to modify,
eliminate or add to any provisions of the Declaration to such extent as shall be
necessary to ensure that the Trust will be classified for United States federal
income tax purposes as 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 Investment Company Act, or (iii) to modify,
eliminate or add any provisions of the Declaration to such extent as shall be
necessary to enable the Trust and the Corporation to conduct an exchange offer
in the manner contemplated by the Registration Rights Agreement; provided,
however, that in the case of clauses (i) and (iii), such action shall not
adversely affect in any material respect the interests of the holders of the
Trust Securities. Any amendments of the Declaration pursuant to the foregoing
shall become effective when notice thereof is given to the holders of the Trust
Securities. The Declaration may be amended by the Issuer Trustees and the
Corporation, as Sponsor, (i) with the consent of holders representing a majority
(based upon Liquidation Amount) of the outstanding Trust Securities and (ii)
upon 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 Trust's status as a grantor
trust for United States federal income tax purposes or the Trust's exemption
from status as an "investment company" under the Investment Company Act,
provided that, without the consent of each holder of Trust Securities, the
Declaration 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; it
being understood that the New Capital Securities and any Old Capital Securities
which remain outstanding after consummation of the Exchange Offer will vote
together as a single class for purposes of determining whether holders of the
requisite percentage in outstanding Liquidation Amount thereof have taken
certain actions or exercised certain rights under the Declaration.

         So long as any 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
execute any trust or power conferred on the Debenture Trustee with respect to
the Junior Subordinated Debentures, (ii) waive certain past defaults under the
Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Junior Subordinated
Debentures or (iv) consent to any amendment, modification or termination of the
Indenture or the Junior Subordinated Debentures, where such consent shall be
required, without in each case obtaining the prior approval of the holders of a
majority in Liquidation Amount of all outstanding Capital Securities; provided,
however, that where a consent under the Indenture would require the consent of
each holder of Junior Subordinated Debentures affected thereby, no such consent
shall be given by the Property Trustee without the prior approval of each holder
of the Capital Securities. The Issuer Trustees shall not revoke any action
previously authorized or approved by a vote of the holders of the Capital
Securities except by subsequent vote of such holders. The


                                       47
<PAGE>   49
Property Trustee shall notify each holder of Capital Securities of any notice of
default with respect to the Junior Subordinated Debentures. In addition to
obtaining the foregoing approvals of such holders of the Capital 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 Trust
will not be classified as an association taxable as a corporation for United
States federal income tax purposes on account of such action.

         Any required approval of holders of Capital Securities may be given at
a meeting of such holders convened for such purpose or pursuant to written
consent. The Property Trustee will cause a notice of any meeting at which
holders of Capital 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 Capital Securities in the manner set forth in the
Declaration.

         No vote or consent of the holders of Capital Securities will be
required for the Trust to redeem and cancel the Capital Securities in accordance
with the Declaration.

         Notwithstanding that holders of the Capital Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Capital 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.

         FORM, DENOMINATION, BOOK-ENTRY PROCEDURES AND TRANSFER. New Capital
Securities initially will be represented by one or more Capital Securities in
registered, global form (collectively, the "Global Capital Securities"). The
Global Capital Securities will be deposited upon issuance with the Property
Trustee as custodian for DTC, in New York, New York, and registered in the name
of DTC or its nominee, in each case for credit to an account of a direct or
indirect participant in DTC as described below.

         Except as set forth below, the Global Capital Securities may be
transferred, in whole and not in part, only to another nominee of DTC or to a
successor of DTC or its nominee and only in amounts that would not cause a
holder to own less than 100 Capital Securities. Beneficial interests in the
Global Capital Securities may not be exchanged for Capital Securities in
certificated form except in the limited circumstances described below.

         DTC has advised the Trust and the Corporation that DTC is a limited
purpose trust company organized under the laws of the State of New York, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the Uniform Commercial Code and a "clearing agency" registered
pursuant to the provisions of Section 17A of the Exchange Act. DTC was created
to hold securities for its participating organizations (collectively, the
"Participants") and to facilitate the clearance and settlement of transactions
in those securities between Participants through electronic book-entry changes
in accounts of its Participants, thereby eliminating the need for physical
movement of certificates. Participants include securities brokers and dealers
(including the Initial Purchasers), banks, trust companies, clearing
corporations and certain other organizations. Indirect access to DTC's system
also is available to other entities such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly (collectively, the "Indirect
Participants"). Persons who are not Participants may beneficially own securities
held by or on behalf of DTC only through the Participants or the Indirect
Participants. The ownership interest and transfer of ownership interest of each
actual purchaser of each security held by or on behalf of DTC are recorded on
the records of the Participants and Indirect Participants.

         DTC also has advised the Trust and the Corporation that, pursuant to
procedures established by it, (i) upon deposit of the Global Capital Securities,
DTC will credit the accounts of Participants with portions of the Liquidation
Amount of the Global Capital Securities and (ii) ownership of such interests in
the Global Capital Securities will be shown on, and the transfer of ownership
thereof will be effected only through, records


                                       48
<PAGE>   50
maintained by DTC (with respect to the Participants) or by the Participants and
the Indirect Participants (with respect to other owners of beneficial interests
in the Global Capital Securities).

         EXCEPT AS DESCRIBED BELOW, OWNERS OF BENEFICIAL INTERESTS IN THE GLOBAL
CAPITAL SECURITIES WILL NOT HAVE CAPITAL SECURITIES REGISTERED IN THEIR NAME,
WILL NOT RECEIVE PHYSICAL DELIVERY OF CAPITAL SECURITIES IN CERTIFICATED FORM
AND WILL NOT BE CONSIDERED THE REGISTERED OWNERS OR HOLDERS THEREOF UNDER THE
DECLARATION FOR ANY PURPOSE.

         Payments in respect of the Global Capital Security registered in the
name of DTC or its nominee will be payable by the Property Trustee to DTC in its
capacity as the registered holder under the Declaration. Under the terms of the
Declaration, the Property Trustee will treat the persons in whose names the
Capital Securities, including the Global Capital Securities, are registered as
the owners thereof for the purpose of receiving such payments and for any and
all other purposes whatsoever. Consequently, neither the Property Trustee nor
any agent thereof has or will have any responsibility or liability for (i) any
aspect of DTC's records or any Participant's or Indirect Participant's records
relating to or payments made on account of beneficial interests in the Global
Capital Securities, or for maintaining, supervising or reviewing any of DTC's
records or any Participant's or Indirect Participant's records relating to the
beneficial interests in the Global Capital Securities, or (ii) any other matter
relating to the actions and practices of DTC or any of its Participants or
Indirect Participants. DTC has advised the Trust and the Corporation that its
current practice, upon receipt of any payment in respect of securities such as
the Capital Securities, is to credit the accounts of the relevant Participants
with the payment on the payment date, in amounts proportionate to their
respective holdings in Liquidation Amount of beneficial interests in the
relevant security as shown on the records of DTC unless DTC has reason to
believe it will not receive payment on such payment date. Payments by the
Participants and the Indirect Participants to the beneficial owners of New
Capital Securities will be governed by standing instructions and customary
practices and will be the responsibility of the Participants or the Indirect
Participants and will not be the responsibility of DTC, the Property Trustee,
the Trust or the Corporation. None of the Trust, the Corporation or the Property
Trustee will be liable for any delay by DTC or any of its Participants in
identifying the beneficial owners of the Capital Securities, and the Trust, the
Corporation and the Property Trustee may conclusively rely on and will be
protected in relying on instructions from DTC or its nominee for all purposes.

         Beneficial interests in the Global Capital Securities will trade in
DTC's Same-Day Funds Settlement System and secondary market trading activity in
such interests will therefore settle in immediately available funds, subject in
all cases to the rules and procedures of DTC and its participants.

         DTC has advised the Trust and the Corporation that it will take any
action permitted to be taken by a holder of Capital Securities (including,
without limitation, the presentation of Old Capital Securities for exchange
pursuant to the Exchange Offer) only at the direction of one or more
Participants to whose account with DTC interests in the Global Capital
Securities are credited and only in respect of such portion of the Liquidation
Amount of the Capital Securities as to which such Participant or Participants
has or have given such direction. However, if there is an Event of Default under
the Declaration, DTC reserves the right to exchange the Global Capital
Securities for Capital Securities in certificated form and to distribute such
Capital Securities to its Participants.

         So long as DTC or its nominee is the registered owner of the Global
Capital Securities, DTC or such nominee, as the case may be, will be considered
the sole owner or holder of the Capital Securities represented by the Global
Capital Securities for all purposes under the Declaration.

         The information in this section concerning DTC and its book-entry
system has been obtained from sources that the Trust and the Corporation believe
to be reliable, but neither the Trust nor the Corporation takes responsibility
for the accuracy thereof.


                                       49
<PAGE>   51
         A Global Capital Security is exchangeable for Capital Securities in
registered certificated form if (i) DTC (x) notifies the Trust that it is
unwilling or unable to continue as Depositary for the Global Capital Security
and the Trust thereupon fails to appoint a successor Depositary within 90 days
or (y) has ceased to be a clearing agency registered under the Exchange Act,
(ii) the Corporation in its sole discretion elects to cause the issuance of the
Capital Securities in certificated form or (iii) there shall have occurred and
be continuing an Event of Default or any event which after notice or lapse of
time or both would be an Event of Default under the Declaration.

         PAYMENT AND PAYING AGENCY. Payments in respect of the Capital
Securities held in global form shall be made to the Depositary, which shall
credit the relevant accounts at the Depositary on the applicable Distribution
Dates. Payments in respect of Capital Securities that are not held by the
Depositary shall be made by check mailed to the address of the holder entitled
thereto as such address shall appear on the register maintained by the
Securities Registrar appointed under the Declaration. 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.
The Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Administrative Trustees. In the event that the Property
Trustee shall no longer be the Paying Agent, the Trust 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.

         RESTRICTIONS ON TRANSFER. The Capital Securities will be issued and may
be transferred only in blocks having a Liquidation Amount of not less than
$100,000 (100 Capital Securities). Any attempted sale, transfer or other
disposition of Capital Securities in a block having a Liquidation Amount of less
than $100,000 shall be deemed to be void and of no legal effect whatsoever. Any
such transferee shall be deemed not to be the holder of such Capital Securities
for any purpose, including but not limited to the receipt of Distributions on
such Capital Securities, and such transferee shall be deemed to have no interest
whatsoever in such Capital Securities.

         REGISTRAR AND TRANSFER AGENT. The Property Trustee will act as
registrar and transfer agent for the Capital Securities. Registration of
transfers of the Capital Securities will be effected without charge by or on
behalf of the Trust, but upon payment of any tax or other governmental charges
that may be imposed in connection with any transfer or exchange. The Trust will
not be required to register or cause to be registered the transfer of the
Capital Securities after they 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 the
Declaration and, during the existence of an 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
Declaration at the request of any holder of Trust 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 courses of
action, construe ambiguous provisions in the Declaration or is unsure of the
application of any provision of the Declaration, and the matter is not one on
which holders of the Capital Securities or the Common Securities are entitled
under the Declaration 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 Trust in such a way that the Trust
will not be deemed to be an "investment company" required to be registered under
the Investment Company Act or classified as an association or publicly-traded
partnership taxable as a corporation for United States federal income tax
purposes and so that the Junior Subordinated


                                       50
<PAGE>   52
Debentures will be treated as indebtedness of the Corporation for United States
federal income tax purposes. In this connection, the Corporation and the
Administrative Trustees are authorized to take any action, not inconsistent with
applicable law, the certificate of trust of the Trust or the Declaration, 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 Trust
Securities.

         Holders of the Trust Securities have no preemptive or similar rights.

         The Trust may not borrow money, issue debt, execute mortgages or pledge
any of its assets.

DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES

         The Old Junior Subordinated Debentures were issued and the New Junior
Subordinated Debentures will be issued as a separate series under the Indenture.
The Indenture has been qualified under the Trust Indenture Act. This summary of
certain terms and provisions of the Junior Subordinated Debentures and the
Indenture describes the material terms thereof, but does not purport to be
complete, and where reference is made to particular provisions of the Indenture,
such provisions, including the definitions of certain terms, some of which are
not otherwise defined herein, are qualified in their entirety by reference to
all of the provisions of the Indenture and those terms made a part of the
Indenture by the Trust Indenture Act.

         GENERAL. Concurrently with the issuance of the Old Capital Securities,
the Trust invested the proceeds thereof, together with the consideration paid by
the Corporation for the Common Securities, in Old Junior Subordinated Debentures
issued by the Corporation. Pursuant to the Exchange Offer, the Corporation will
exchange the Old Junior Subordinated Debentures, in an amount corresponding to
the Old Capital Securities accepted for exchange, for a like aggregate principal
amount of the New Junior Subordinated Debentures as soon as practicable after
the date hereof.

         The Junior Subordinated Debentures bear interest at the annual rate of
9.06% of the principal amount thereof, payable semi-annually in arrears on
February 1 and August 1 of each year (each, an "Interest Payment Date"),
commencing August 1, 1997, to the person in whose name each Junior Subordinated
Debenture is registered, subject to certain exceptions, at the close of business
on the fifteenth day of the month which precedes the month in which the relevant
payment date falls. The Junior Subordinated Debentures will mature on February
1, 2027. It is anticipated that, until the liquidation, if any, of the Trust,
each Junior Subordinated Debenture will be held in the name of the Property
Trustee in trust for the benefit of the holders of the Trust 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 and, for any period of less than one
calendar month, the number of days elapsed in such month. In the event that any
date on which interest is payable on the New Junior Subordinated Debentures is
not a Business Day, 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), 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 9.06% thereof, compounded semi-annually. The term "interest", as used
herein, shall include semi-annual interest payments, interest on semi-annual
interest payments not paid on the applicable Interest Payment Date and
Additional Sums (as defined below), as applicable.

         The New Junior Subordinated Debentures rank pari passu with the Old
Junior Subordinated Debentures and with all Other Debentures and are unsecured
and are subordinate and junior in right of payment to the extent and in the
manner set forth in the Indenture to all Senior Indebtedness. See
"--Subordination." The Corporation is a holding company and almost all of the
operating assets of the Corporation and its consolidated subsidiaries are owned
by such subsidiaries. The Corporation relies primarily on dividends from such
subsidiaries


                                       51
<PAGE>   53
to meet its obligations. The Corporation is a legal entity separate and distinct
from its banking and non-banking affiliates. The principal sources of the
Corporation's income are dividends, interest and fees from its banking and
non-banking affiliates. The Banks are subject to certain restrictions imposed by
federal law on any extensions of credit to, and certain other transactions with,
the Corporation and certain other affiliates, and on investments in stock or
other securities thereof. Such restrictions prevent the Corporation and such
other affiliates from borrowing from the Banks unless the loans are secured by
various types of collateral. Further, such secured loans, other transactions and
investments by any of the Banks are generally limited in amount as to the
Corporation and as to each of such other affiliates to 10% of such Bank's
capital and surplus and as to the Corporation and all of such other affiliates
to an aggregate of 20% of such Bank's capital and surplus. In addition, payment
of dividends to the Corporation by the Banks is subject to ongoing review by
banking regulators and is subject to various statutory limitations and in
certain circumstances requires approval by banking regulatory authorities.
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. The Indenture does not limit the
incurrence or issuance of other secured or unsecured debt of the Corporation,
including Senior Indebtedness. See "--Subordination."

         FORM, REGISTRATION AND TRANSFER. In the event that the Junior
Subordinated Debentures are distributed to holders of the Trust Securities, such
Junior Subordinated Debentures may be represented by one or more global
certificates registered in the name of Cede & Co. as the nominee of DTC. It is
anticipated that the depositary arrangements for such Junior Subordinated
Debentures will be substantially similar to those in effect for the Capital
Securities. 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 "--Description of Capital Securities--Form,
Denomination, Book-Entry Procedures and Transfer."

         The Junior Subordinated Debentures will be issuable only in registered
form without coupons in minimum denominations of $100,000 and integral multiples
of $1,000 in excess thereof.

         PAYMENT AND PAYING AGENTS. 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,
except that at the option of the Corporation payment of any interest may be made
(except in the case of Junior Subordinated Debentures in global form), (i) by
check mailed to the address of the Person entitled thereto as such address shall
appear in the register for Junior Subordinated Debentures or (ii) by transfer to
an account maintained by the Person entitled thereto as specified in such
register, provided that proper transfer instructions have been received by the
relevant Record Date. Payment of any interest on any Junior Subordinated
Debenture will be made to the Person in whose name such Junior Subordinated
Debenture is registered at the close of business on the 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 the 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


                                       52
<PAGE>   54
of such Junior Subordinated Debenture shall thereafter look, as a general
unsecured creditor, only to the Corporation for payment thereof.

         OPTION TO EXTEND INTEREST PAYMENT DATE. So long as no Debenture Event
of Default has occurred and is continuing, the Corporation will have the right
under the Indenture to defer the payment of interest on the Junior Subordinated
Debentures at any time or from time to time for a period not exceeding 10
consecutive semi-annual periods with respect to each Extension Period, provided,
however, that no Extension Period may extend beyond the Stated Maturity Date. At
the end of such Extension Period, the Corporation must pay all interest then
accrued and unpaid (together with interest thereon accrued at the annual rate of
9.06%, compounded semi-annually from the relevant Interest Payment Date, to the
extent permitted by applicable law). During an Extension Period, interest will
continue to accrue and holders of Junior Subordinated Debentures (and holders of
the Trust Securities while Trust Securities are outstanding) will be required to
accrue interest income for United States federal income tax purposes prior to
the receipt of cash attributable to such income. See "Certain Federal Income Tax
Considerations--Interest Income and Original Issue Discount."

         During any such Extension Period, the Corporation may not (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
(which includes common and preferred 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 any Other Debentures) that rank pari
passu with or junior in right of payment 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
(including any Other Guarantees) if such guarantee ranks pari passu with or
junior in right of payment to the Junior Subordinated Debentures (other than (a)
dividends or distributions in shares of or options, warrants or rights to
subscribe for or purchase shares of, common stock of the Corporation, (b) any
declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under the Guarantee, (d) as a result of, and only to the extent
required in order to avoid the issuance of fractional shares of capital stock
following, a reclassification of the Corporation's capital stock or the exchange
or conversion of one class or series of the Corporation's capital stock for
another class or series of the Corporation's capital stock, (e) the purchase of
fractional interests in shares of the Corporation's capital stock pursuant to
the conversion or exchange provisions of such capital stock or the security
being converted or exchanged and (f) 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 or any of the Corporation's dividend
reinvestment plans).

         Prior to the termination of any such Extension Period, the Corporation
may further extend such Extension Period, provided, however, that such extension
does not cause such Extension Period to exceed 10 consecutive semi-annual
periods or to extend beyond the Stated Maturity Date. Upon the termination of
any such Extension Period and the payment of all amounts then due on any
Interest Payment Date, 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 of any Extension Period (or an extension thereof) at
least five Business Days prior to the earlier of (i) the date the Distributions
on the Trust Securities would have been payable except for the election to begin
or extend such Extension Period or (ii) the date the Administrative Trustees are
required to give notice to any securities exchange or to holders of Capital
Securities of the record date for such Distributions or the date such
Distributions are payable, but in any event not less than five Business Days
prior to such record date. The Debenture Trustee shall give notice of the
Corporation's election to begin or extend a new Extension Period to the holders
of the Capital Securities. There is no limitation on the number of times that
the Corporation may elect to begin an Extension Period.

         OPTIONAL PREPAYMENT. The Junior Subordinated Debentures will be
prepayable, in whole or in part, at the option of the Corporation on or after
February 1, 2007 subject to the Corporation having received prior approval of
the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve, at a prepayment price (the "Optional Prepayment
Price") equal to the percentage of the outstanding principal amount of the
Junior Subordinated Debentures specified below, plus, in each case, accrued
interest thereon to the date of prepayment if prepaid during the 12-month period
beginning February 1 of the years indicated below:

         SPECIAL EVENT PREPAYMENT. If a Special Event shall occur and be
continuing, the Corporation may, at any time prior to the Initial Optional
Prepayment Date, within 90 days after the occurrence of the Special Event, at
its option and subject to receipt of prior approval of the Federal Reserve if
then required under applicable capital guidelines or policies of the Federal
Reserve, prepay the Junior Subordinated Debentures in whole (but not in part),
at a prepayment price (the "Special Event Prepayment Price") equal to the
greater of (i) 100% of the principal amount of such Junior Subordinated
Debentures or (ii) the sum, as determined by a Quotation Agent, of the present
values of the principal amount and premium payable as part of the Optional
Prepayment Price with respect to an optional redemption of such Junior
Subordinated Debentures on the Initial Optional Prepayment Date, together with
scheduled payments of interest from the prepayment date to the Initial Optional
Prepayment Date, in each case discounted to the prepayment date on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the
Adjusted Treasury Rate, plus in each case accrued and unpaid interest thereon to
the date of prepayment.

         A "Special Event" means a Tax Event or a Regulatory Capital Event (as
defined below), as the case may be.

         A "Tax Event" means the receipt by the Corporation and the Trust of an
opinion of a nationally-recognized tax counsel experienced in such matters to
the effect that, as a result of any amendment to, or change (including any
announced prospective 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 pronouncement or decision is announced on or after
the Issue Date, there is more than an insubstantial risk that (i) the Trust 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 Junior
Subordinated Debentures, (ii) interest payable by the Corporation on the 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) the Trust 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.


                                       54
<PAGE>   56
         A "Regulatory Capital Event" means that the Corporation shall have
received an opinion of independent bank regulatory counsel experienced in such
matters to the effect that, as a result of (i) any amendment to, or change
(including any announced prospective change) in, the laws (or any regulations
thereunder) of the United States or any rules, guidelines or policies of the
Federal Reserve or (ii) any official administrative pronouncement or judicial
decision interpreting or applying such laws or regulations, which amendment or
change is effective or such pronouncement or decision is announced on or after
the Issue Date, the Capital Securities do not constitute, or within 90 days of
the date of such opinion, will not constitute, Tier 1 Capital (or its then
equivalent); provided, however, that the distribution of the Junior Subordinated
Debentures in connection with a termination of the Trust by the Corporation
shall not in and of itself constitute a Regulatory Capital Event.

         "Adjusted Treasury Rate" means, with respect to any prepayment date,
the rate per annum equal to (i) the yield, under the heading which represents
the average for the immediately prior week, appearing in the most recently
published statistical release designated "H.15(519)" or any successor
publication which is published weekly by the Federal Reserve and which
established yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption "Treasury Constant Maturities," for the
maturity date corresponding to the Initial Optional Prepayment Date (if no
maturity date is within three months before or after the Initial Optional
Prepayment Date, yields for the two published maturities most closely
corresponding to the Initial Optional Prepayment Date shall be interpolated and
the Adjusted Treasury Rate shall be interpolated or extrapolated from such
yields on a straight-line basis, rounding to the nearest month) or (ii) if such
release (or any successor release) is not published during the week preceding
the calculation date or does not contain such yields, the rate per annum equal
to the semi-annual equivalent yield to maturity of the Comparable Treasury
Issue, assuming a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price for
such prepayment date plus, in either case (A) 1.85% if such prepayment date
occurs on or prior to January 31, 1998 and (B) 1.50% in all other cases.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity date corresponding to the
Initial Optional Prepayment Date that would be utilized at the time of selection
and in accordance with customary financial practice, in pricing new issues of
corporate debt securities with a maturity date corresponding to the Initial
Optional Prepayment Date. If no United States Treasury security has a maturity
date which is within three months before or after the Initial Optional
Prepayment Date, the two most closely corresponding United States Treasury
securities shall be used as the Comparable Treasury Issue, and the calculation
of the Adjusted Treasury Rate pursuant to clause (ii) of the definition thereof
shall be interpolated or extrapolated on a straight-line basis, rounding to the
nearest month.

         "Quotation Agent" means the Reference Treasury Dealer appointed by the
Corporation. "Reference Treasury Dealer" means: (i) Lehman Brothers and its
respective successors; provided, however, that if the foregoing shall cease to
be a primary U.S. Government securities dealer in New York City (a "Primary
Treasury Dealer"), the Corporation shall substitute therefor another Primary
Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by the
Corporation.

         "Comparable Treasury Price" means, with respect to any prepayment date,
(i) the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day preceding such prepayment date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such Business Day, (A) the average
of five Reference Treasury Dealer Quotations for such prepayment date, after
excluding the highest and lowest such Reference Treasury Dealer Quotations, or
(B) if the Debenture Trustee obtains fewer than three such Reference Treasury
Dealer Quotations, the average of all such Quotations.


                                       55
<PAGE>   57
         "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any prepayment date, the average, as determined by
the Debenture Trustee, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Debenture Trustee by such Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third Business Day preceding such prepayment date.

         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 prepaid at its registered address. Unless the Corporation
defaults in payment of the prepayment price, on and after the prepayment date
interest ceases to accrue on such Junior Subordinated Debentures called for
prepayment.

         ADDITIONAL SUMS. If the Trust 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 Junior Subordinated Debentures such
amounts as shall be necessary in order that the amount of Distributions then due
and payable by the Trust on the outstanding Capital Securities and Common
Securities shall not be reduced as a result of any such additional taxes, duties
or other governmental charges.

         CERTAIN COVENANTS OF THE CORPORATION. The Corporation has agreed that
it will not (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 (which includes common and preferred 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
Debentures) that rank pari passu with or junior in right of payment 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 (including under Other Guarantees) if such guarantee ranks pari
passu or junior in right of payment to the Junior Subordinated Debentures (other
than (a) dividends or distributions in shares of, or options, warrants or rights
to subscribe for or purchase shares of, common stock of the Corporation, (b) any
declaration of a dividend in connection with the implementation of a
stockholder's rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under the Guarantee, (d) as a direct result of, and only to the extent
required in order to avoid the issuance of fractional shares of capital stock
following, a reclassification of the Corporation's capital stock or the exchange
or conversion of one class or series of the Corporation's capital stock for
another class or series of the Corporation's capital stock, (e) the purchase of
fractional interests in shares of the Corporation's capital stock pursuant to
the conversion or exchange provisions of such capital stock or the security
being converted or exchanged, and (f) 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 or any of the Corporation's dividend
reinvestment plans) if at such time (1) there shall have occurred any event of
which the Corporation has actual knowledge that (a) is, or with the giving of
notice or the lapse of time, or both, would be, a Debenture Event of Default and
(b) in respect of which the Corporation shall not have taken reasonable steps to
cure, (2) if such Junior Subordinated Debentures are held by the Trust, the
Corporation shall be in default with respect to its payment of any obligations
under the Guarantee or (3) the Corporation shall have given notice of its
election of an Extension Period as provided in the Indenture and shall not have
rescinded such notice, and such Extension Period, or any extension thereof,
shall have commenced.

         DEBENTURE EVENTS OF DEFAULT. The Indenture provides that any one or
more of the following described events with respect to the Junior Subordinated
Debentures constitutes a Debenture Event of Default (whatever the reason for
such Debenture 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):


                                       56
<PAGE>   58
         (i) failure for 30 days to pay any interest on the Junior Subordinated
Debentures or any Other Debentures, when due (subject to the deferral of any due
date in the case of an Extension Period); or

         (ii) failure to pay any principal or premium, if any, on the Junior
Subordinated Debentures or any Other Debentures when due, whether at maturity,
upon redemption, by declaration of acceleration of maturity or otherwise; 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 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
the Junior Subordinated Debentures 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 the Junior Subordinated Debentures may declare
the principal due and payable immediately upon a Debenture Event of Default. The
holders of a majority in aggregate outstanding principal amount of the Junior
Subordinated Debentures may annul such declaration and waive the default if the
default (other than the nonpayment of the principal of the Junior Subordinated
Debentures which has become due solely by such acceleration) 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.

         The holders of a majority in aggregate outstanding principal amount of
the Junior Subordinated Debentures affected thereby may, on behalf of the
holders of all the Junior Subordinated Debentures, waive any past default,
except a default in the payment of principal of or premium, if any, on or
interest (unless such default has been cured and a sum sufficient to pay all
matured installments of interest and premium, if any, 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.

         The Indenture requires the annual filing by the Corporation with the
Debenture Trustee of a certificate as to the absence of certain defaults under
the Indenture.

         The Indenture provides that the Debenture Trustee may withhold notice
of a Debenture Event of Default from the holders of the Junior Subordinated
Debentures (except a Debenture Event of Default in payment of principal of or
premium, if any, or interest on the Junior Subordinated Debentures) if the
Debenture Trustee considers it in the interest of such holders to do so.

         ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF CAPITAL SECURITIES. If (i)
a Debenture Event of Default shall have occurred and be continuing and (ii) such
event shall be attributable to the failure of the Corporation to pay interest or
premium, if any, on or principal of the Junior Subordinated Debentures on the
due date, then a holder of Capital Securities may institute 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
Capital Securities. Notwithstanding any payments made to a holder of Capital
Securities by the Corporation in connection with a Direct Action, the
Corporation shall remain obligated to pay the principal of or premium, if any,
or interest on the Junior Subordinated Debentures, and the Corporation shall be
subrogated to the rights of the holder of such Capital Securities to the extent
of any payments made by the Corporation to such holder in any Direct Action.


                                       57
<PAGE>   59
         The holders of the Capital 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 Declaration. See "--Description of
Capital 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 as an
entirety or 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 as an entirety or 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
New Junior Subordinated Debentures; (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; and (iii) certain other conditions as prescribed in
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.

         MODIFICATION OF INDENTURE. From time to time the Corporation and the
Debenture Trustee may, without the consent of the holders 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 Junior Subordinated Debentures) 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 a majority in principal amount of Junior
Subordinated Debentures, to modify the Indenture in a manner affecting the
rights of the holders of Junior Subordinated Debentures; provided, that no such
modification may, without the consent of the holders of each outstanding Junior
Subordinated Debenture so affected, (i) change the Stated Maturity, or reduce
the principal amount of the Junior Subordinated Debentures 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, the holders of which are
required to consent to any such modification of the Indenture.

         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.

         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 Date 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 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 Date, 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.


                                       58
<PAGE>   60
         SUBORDINATION. The Indenture provides that the Junior Subordinated
Debentures will be subordinate and junior in right of payment to all Senior
Indebtedness to the extent provided in the Indenture. Upon any payment or
distribution of assets 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 Indebtedness will first be entitled to receive payment in
full of all Senior Indebtedness before the holders of Junior Subordinated
Debentures will be entitled to receive or retain any payment in respect thereof.

         In the event of the acceleration of the maturity of Junior Subordinated
Debentures, the holders of all Senior Indebtedness outstanding at the time of
such acceleration will first be entitled to receive payment in full before the
holders of Junior Subordinated Debentures will be entitled to receive or retain
any payment in respect of the Junior Subordinated Debentures.

         No payments on account of principal or premium, if any, or interest, if
any, 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
Indebtedness, or an event of default with respect to any Senior Indebtedness
resulting in the acceleration of the maturity thereof, or if any judicial
proceeding shall be pending with respect to any such default.

         "Indebtedness" shall mean (i) every obligation of the Corporation for
money borrowed; (ii) every obligation of the Corporation 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 the Corporation with respect to letters of
credit, bankers' acceptances or similar facilities issued for the account of the
Corporation; (iv) every obligation of the Corporation 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 the Corporation; (vi) all indebtedness of the
Corporation whether incurred on or prior to the date of the Indenture or
thereafter incurred, for claims in respect of derivative products, including
interest rate, foreign exchange rate and commodity forward contracts, options
and swaps 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, the Corporation has
guaranteed or is responsible or liable, directly or indirectly, as obligor or
otherwise.

         "Indebtedness Ranking on a Parity with the Junior Subordinated
Debentures" shall mean Indebtedness, whether outstanding on the date of
execution of the Indenture or thereafter created, assumed or incurred, which
specifically by its terms ranks equally with and not prior to the Junior
Subordinated Debentures in the right of payment upon the happening of the
dissolution or winding-up or liquidation or reorganization of the Corporation.
The securing of any Indebtedness, otherwise constituting Indebtedness Ranking on
a Parity with the Junior Subordinated Debentures, shall not be deemed to prevent
such Indebtedness from constituting Indebtedness Ranking on a Parity with the
Junior Subordinated Debentures.

         "Indebtedness Ranking Junior to the Junior Subordinated Debentures"
shall mean any Indebtedness, whether outstanding on the date of execution of the
Indenture or thereafter created, assumed or incurred, which specifically by its
terms ranks junior to and not equally with or prior to the Junior Subordinated
Debentures (and any other Indebtedness Ranking on a Parity with the Junior
Subordinated Debentures) in right of payment upon the happening of the
dissolution or winding-up or liquidation or reorganization of the Corporation.
The securing of any Indebtedness, otherwise constituting Indebtedness Ranking
Junior to the Junior Subordinated Debentures, shall not be deemed to prevent
such Indebtedness from constituting Indebtedness Ranking Junior to the Junior
Subordinated Debentures.


                                       59
<PAGE>   61
         "Senior Indebtedness" shall mean all Indebtedness, whether outstanding
on the date of execution of the Indenture or thereafter created, assumed or
incurred, except Indebtedness Ranking on a Parity with the Junior Subordinated
Debentures or Indebtedness Ranking Junior to the Junior Subordinated Debentures,
and any deferrals, renewals or extensions of such Senior Indebtedness.

         The Corporation is a holding company and almost all of the operating
assets of the Corporation are owned by the Corporation's subsidiaries. The
Corporation relies primarily on dividends from such subsidiaries to meet its
obligations for payment of principal and interest on its outstanding debt
obligations and corporate expenses. The Corporation is a legal entity separate
and distinct from its banking and non-banking affiliates. The principal sources
of the Corporation's income are dividends, interest and fees from its banking
and non-banking affiliates. The Banks are subject to certain restrictions
imposed by federal law on any extensions of credit to, and certain other
transactions with, the Corporation and certain other affiliates, and on
investments in stock or other securities thereof. Such restrictions prevent the
Corporation and such other affiliates from borrowing from the Banks unless the
loans are secured by various types of collateral. Further, such secured loans,
other transactions and investments by any of the Banks are generally limited in
amount as to the Corporation and as to each of such other affiliates to 10% of
such Bank's capital and surplus and as to the Corporation and all of such other
affiliates to an aggregate of 20% of such Bank's capital and surplus. In
addition, payment of dividends to the Corporation by the subsidiary banks is
subject to ongoing review by banking regulators and is subject to various
statutory limitations and in certain circumstances requires approval by banking
regulatory authorities. Accordingly, the Junior Subordinated Debentures
effectively are subordinated to all existing and future liabilities of the
Corporation's subsidiaries. Holders of Junior Subordinated Debentures should
look only to the assets of the Corporation for payments of interest and
principal and premium, if any.

         The Indenture places no limitation on the amount of additional Senior
Indebtedness that may be incurred by the Corporation. The Corporation expects
from time to time to incur additional indebtedness constituting Senior
Indebtedness. At December 31, 1996, the aggregate outstanding Senior
Indebtedness of the Corporation was $6.5 million.

         RESTRICTIONS ON TRANSFER. The Junior Subordinated Debentures will be
issued, and may be transferred only, in blocks having an aggregate principal
amount of not less than $100,000 and multiples of $1,000 in excess thereof. Any
such transfer of Junior Subordinated Debentures in a block having an aggregate
principal amount of less than $100,000 shall be deemed to be void and of no
legal effect whatsoever. Any such transferee shall be deemed not to be holder of
such Junior Subordinated Debentures for any purpose, including but not limited
to the receipt of payments on such Junior Subordinated Debentures, and such
transferee shall be deemed to have no interest whatsoever in such Junior
Subordinated Debentures.

         GOVERNING LAW. The Indenture and the Junior Subordinated Debentures are
governed by and construed in accordance with the laws of the State of New York.

         INFORMATION CONCERNING THE DEBENTURE TRUSTEE. Following the Exchange
Offer and the qualification of the Indenture under the Trust Indenture Act, 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.

DESCRIPTION OF GUARANTEE

         The Old Guarantee was executed and delivered by the Corporation
concurrently with the issuance by the Trust of the Old Capital Securities for
the benefit of the holders from time to time of the Old Capital Securities. As
soon as practicable after the date hereof, the Old Guarantee will be exchanged
by the Corporation for the New Guarantee for the benefit of the holders from
time to time of the New Capital Securities. The Guarantee Agreement has been
qualified under the Trust Indenture Act. This summary of certain provisions of
the Guarantee Agreement describes the material terms of the Guarantee, but does
not purport to be complete and is subject to, and qualified in its entirety by
reference to, all of the provisions of the Guarantee Agreement, including the
definitions therein of certain terms, and the Trust Indenture Act. The Guarantee
Trustee will hold the Guarantee for the benefit of the holders of the Capital
Securities.

         GENERAL. The Corporation has agreed 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 Capital Securities, as and when due, regardless of any
defense, right of set-off or counterclaim that the Trust may have or assert
other than the defense of payment. The following payments with respect to the
Capital Securities, to the extent not paid by or on behalf of the Trust (the
"Guarantee Payments"), are subject to the Guarantee: (i) any accumulated and
unpaid Distributions required to be paid on the Capital Securities, to the
extent that the Trust has funds on hand legally available therefor at such time,
(ii) the Redemption Price with respect to any Capital Securities called for
redemption, to the extent that the Trust has funds on hand legally available
therefor at such time, or (iii) upon a voluntary or involuntary dissolution,
winding-up or liquidation of the Trust (other than in connection with the
distribution of the Junior Subordinated Debentures to holders of the Capital
Securities or the redemption of all of the Capital Securities), the lesser of
(a) the Liquidation Distribution, to the extent the Trust has funds legally
available therefor, and (b) the amount of assets of the Trust remaining
available for distribution to holders of Capital Securities upon liquidation of
the Trust after satisfaction of liabilities to creditors of the Trust 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 Capital Securities or by causing the Trust to
pay such amounts to such holders.

         The Guarantee ranks subordinate and junior in right of payment to all
Senior Indebtedness to the extent provided therein. See "--Status of Guarantee."
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 Guarantee effectively are subordinated to
all existing and future liabilities, including deposits, of the Corporation's
subsidiaries, and claimants should look only to the assets of the Corporation
for payments thereunder. See "--Description of Junior Subordinated
Debentures--General." The Guarantee does not limit the incurrence or issuance of
other secured or unsecured debt of the Corporation, including Senior
Indebtedness, whether under the Indenture, any other indenture that the
Corporation may enter into in the future or otherwise.

         The Corporation has, through the Guarantee, the Declaration, the Junior
Subordinated Debentures and the Indenture, taken together, fully, irrevocably
and unconditionally guaranteed all of the Trust's obligations under the Capital
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 Trust's obligations under the
Capital Securities. See "Relationship Among the Capital Securities, the Junior
Subordinated Debentures and the Guarantee."

         STATUS OF GUARANTEE. The Guarantee constitutes an unsecured obligation
of the Corporation and ranks subordinate and junior in right of payment to all
Senior Indebtedness in the same manner as Junior Subordinated


                                       61
<PAGE>   63
Debentures, except in the case of a bankruptcy or insolvency proceeding in
respect of the Corporation, in which case the Guarantee will rank subordinate
and junior in right of payment to all liabilities (other than Other Guarantees)
of the Corporation.

         The New Guarantee ranks pari passu with the Old Guarantee and with all
Other Guarantees issued by the Corporation. The Guarantee constitutes a
guarantee of payment and not of collection (i.e., the guaranteed party may
institute a legal proceeding directly against the Corporation to enforce its
rights under the Guarantee without first instituting a legal proceeding against
any other person or entity). The Guarantee will be held for the benefit of the
holders of the Capital Securities. The Guarantee will not be discharged except
by payment of the Guarantee Payments in full to the extent not paid by the Trust
or upon distribution to the holders of the Capital Securities of the Junior
Subordinated Debentures. The Guarantee does not place a limitation on the amount
of additional Senior Indebtedness that may be incurred by the Corporation. The
Corporation expects from time to time to incur additional indebtedness
constituting Senior Indebtedness.

         EVENTS OF DEFAULT. An event of default under the Guarantee will occur
upon the failure of the Corporation to perform any of its payment or other
obligations thereunder, provided, however, that except with respect to a default
in payment of any Guarantee Payment, the Corporation shall have received notice
of default and shall not have cured such default within 60 days after receipt of
such notice. The holders of not less than a majority in Liquidation Amount of
the Capital Securities will 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 Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under the Guarantee.

         Any holder of the Capital Securities may institute a legal proceeding
directly against the Corporation to enforce its rights under the Guarantee
without first instituting a legal proceeding against the Trust, the Guarantee
Trustee or any other person or entity.

         The Corporation, as guarantor, will be 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.

         AMENDMENTS AND ASSIGNMENT. Except with respect to any changes that do
not materially adversely affect the rights of holders of the Capital Securities
(in which case no vote will be required), the Guarantee may not be amended
without the prior approval of the holders of a majority of the Liquidation
Amount of outstanding Capital Securities. The manner of obtaining any such
approval will be as set forth under "--Description of Capital Securities--Voting
Rights; Amendment of the Declaration." All guarantees and agreements contained
in the Guarantee Agreement shall bind the successors, assigns, receivers,
trustees and representatives of the Corporation and shall inure to the benefit
of the holders of the Capital Securities then outstanding.

         TERMINATION. The Guarantee will terminate and be of no further force
and effect upon full payment of the applicable Redemption Price of the Capital
Securities, upon full payment of the Liquidation Amount payable upon liquidation
of the Trust or upon distribution of Junior Subordinated Debentures to the
holders of the Capital Securities. The Guarantee will continue to be effective
or will be reinstated, as the case may be, if at any time any holder of the
Capital Securities must restore payment of any sums paid under the Capital
Securities or the Guarantee.

         INFORMATION CONCERNING THE GUARANTEE TRUSTEE. The Guarantee Trustee,
other than during the occurrence and continuance of a default by the Corporation
in performance of the Guarantee, will undertake to perform only such duties as
are specifically set forth in the Guarantee and, after default with respect to
the Guarantee, must exercise the same degree of care and skill as a prudent
person would exercise or use in the


                                       62
<PAGE>   64
conduct of his or her own affairs. Subject to this provision, the Guarantee
Trustee will be under no obligation to exercise any of the powers vested in it
by the Guarantee at the request of any holder of the Capital Securities unless
it is offered reasonable indemnity against the costs, expenses and liabilities
that might be incurred thereby.

         GOVERNING LAW. The Guarantee will be governed by and construed in
accordance with the laws of the State of New York.

                          DESCRIPTION OF OLD SECURITIES

         The terms of the Old Securities are identical in all materials respects
to the New Securities, except that (i) the Old Securities have not been
registered under the Securities Act, are subject to restrictions on transfer
under federal and state securities laws and are entitled to certain rights under
the Registration Rights Agreement (which rights will terminate upon consummation
of the Exchange Offer), (ii) the New Capital Securities will not provide for any
increase in the Distribution rate thereon and (iii) the New Junior Subordinated
Debentures will not provide for any increase in the interest rate thereon. The
Old Securities provide that, in the event that a registration statement relating
to the Exchange Offer has not been filed by June 30, 1997 and declared effective
by July 30, 1997, or, in certain limited circumstances, in the event a shelf
registration statement (the "Shelf Registration Statement") with respect to the
resale of the Old Capital Securities is not declared effective by July 30, 1997,
then interest will accrue (in addition to the stated interest rate on the Old
Junior Subordinated Debentures) at the rate of 0.25% per annum on the principal
amount of the Old Junior Subordinated Debentures and Distributions will accrue
(in addition to the stated Distribution rate on the Old Capital Securities) at
the rate of 0.25% per annum on the Liquidation Amount of the Old Capital
Securities, for the period from the occurrence of such event until such time as
such required Exchange Offer is consummated or any required Shelf Registration
Statement is effective. The New Securities are not, and upon consummation of the
Exchange Offer the Old Securities will not be, entitled to any such additional
interest or Distributions.  Accordingly, holders of Old Capital Securities
should review the information set forth under "Risk Factors--Consequences of a
Failure to Exchange Old Capital Securities" and "Description of New Securities."


                 RELATIONSHIP AMONG THE CAPITAL SECURITIES, THE
                JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEE

FULL AND UNCONDITIONAL GUARANTEE

         Payments of Distributions and other amounts due on the Capital
Securities (to the extent the Trust has funds on hand legally available for the
payment of such Distributions) are guaranteed by the Corporation as and to the
extent set forth under "Description of New Securities--Description of
Guarantee." Taken together, the Corporation's obligations under the Junior
Subordinated Debentures, the Indenture, the Declaration and the Guarantee
provide, in the aggregate, a full, irrevocable and unconditional guarantee of
payments of Distributions and other amounts due on the Capital 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 Trust's obligations under the
Capital Securities. If and to the extent that the Corporation does not make the
required payments on the Junior Subordinated Debentures, the Trust will not have
sufficient funds to make the related payments, including Distributions, on the
Capital Securities. The Guarantee does not cover any such payment when the Trust
does not have sufficient funds on hand legally available therefor. In such
event, the remedy of a holder of Capital Securities is to institute a Direct
Action. The obligations of the Corporation under the Guarantee are subordinate
and junior in right of payment to all Senior Indebtedness.


                                       63
<PAGE>   65
SUFFICIENCY OF PAYMENTS

         As long as payments of interest and other payments are made when due on
the Junior Subordinated Debentures, such payments will be sufficient to cover
Distributions and other payments due on the Capital Securities, primarily
because: (i) the aggregate principal amount or Prepayment Price of the Junior
Subordinated Debentures will be equal to the sum of the Liquidation Amount or
Redemption Price, as applicable, of the Capital Securities and Common
Securities, (ii) the interest rate and interest and other payment dates on the
Junior Subordinated Debentures will match the Distribution rate and Distribution
and other payment dates for the Capital Securities; (iii) the Corporation shall
pay for all and any costs, expenses and liabilities of the Trust except the
Trust's obligations to holders of Capital Securities under such Capital
Securities; and (iv) the Declaration provides that the Trust is not authorized
to engage in any activity that is not consistent with the limited purposes
thereof.

         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
Guarantee.

         A principal difference between the rights of a holder of Capital
Securities and a holder of Junior Subordinated Debentures is that a holder of
Junior Subordinated Debentures is entitled to receive from the Corporation the
principal amount of (and premium, if any) and interest on Junior Subordinated
Debentures held, while a holder of Capital Securities is entitled to receive
Distributions from the Trust (or, in certain circumstances, from the Corporation
under the Guarantee) if and to the extent the Trust has funds on hand legally
available for the payment of such Distributions.

ENFORCEMENT RIGHTS OF HOLDERS OF CAPITAL SECURITIES

         A holder of any Capital Security may institute a legal proceeding
directly against the Corporation to enforce its rights under the Guarantee
without first instituting a legal proceeding against the Guarantee Trustee, the
Trust or any other person or entity.

         A default or event of default under any Senior Indebtedness would not
constitute a Debenture Event of Default, and therefore would not constitute an
Event of Default under the Declaration. However, in the event of payment
defaults under, or acceleration of, Senior Indebtedness, the subordination
provisions of the Indenture provide that no payments may be made in respect of
the Junior Subordinated Debentures until such Senior Indebtedness has been paid
in full or any payment default thereunder has been cured or waived. Failure to
make required payments on Junior Subordinated Debentures would constitute a
Debenture Event of Default, and therefore an Event of Default under the
Declaration.

LIMITED PURPOSE OF THE TRUST

         The Trust exists for the sole purpose of issuing and selling the Trust
Securities, using the proceeds from the sale of the Trust Securities to acquire
the Junior Subordinated Debentures and engaging in only those other activities
necessary, advisable or incidental thereto. The Capital Securities represent
beneficial ownership interests in the Trust.

RIGHTS UPON TERMINATION

         Unless the Junior Subordinated Debentures are distributed to holders of
the Trust Securities, upon any voluntary or involuntary termination, winding-up
or liquidation of the Trust, after satisfaction of the liabilities of creditors
of the Trust as required by applicable law, the holders of the Trust Securities
will be entitled to receive, out of assets held by the Trust, the Liquidation
Distribution in cash. See "Description of New Securities


                                       64
<PAGE>   66
- --Description of Capital Securities--Liquidation of the Trust and Distribution
of Junior Subordinated Debentures." Upon any voluntary or involuntary
liquidation or bankruptcy of the Corporation, the Property Trustee, as holder of
the Junior Subordinated Debentures, would be a subordinated creditor of the
Corporation, subordinated in right of payment to all Senior Indebtedness as set
forth in the Indenture, but entitled to receive payment in full of principal
(and premium, if any) and interest, before any stockholders of the Corporation
receive payments or distributions. Since the Corporation is the guarantor under
the Guarantee and has agreed to pay for all costs, expenses and liabilities of
the Trust (other than the Trust's obligations to the holders of its Trust
Securities), the positions of a holder of Capital Securities and a holder of
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.

                    CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

GENERAL

         In the opinion of Elias, Matz, Tiernan & Herrick L.L.P., special
federal income tax counsel to the Corporation and the Trust ("Tax Counsel"), the
following is a summary of certain of the material United States federal income
tax consequences of the purchase, ownership and disposition of Capital
Securities held as capital assets by a holder. This summary does not deal with
special classes of holders such as banks, thrifts, real estate investment
trusts, regulated investment companies, insurance companies, dealers in
securities or currencies, tax-exempt investors, or persons that will hold the
Capital Securities as a position in a "straddle," as part of a "synthetic
security" or "hedge," as part of a "conversion transaction" or other integrated
investment, or as other than a capital asset. This summary also does not address
the tax consequences to persons that have a functional currency other than the
U.S. dollar or the tax consequences to shareholders, partners or beneficiaries
of a holder of Capital Securities. Further, it does not include any description
of any alternative minimum tax consequences or the tax laws of any state or
local government or of any foreign government that may be applicable to the
Capital Securities. This summary is based on the Internal Revenue Code of 1986,
as amended (the "Code"), Treasury regulations thereunder, the administrative and
judicial interpretations thereof, as of the date hereof, all of which are
subject to change, possibly on a retroactive basis. An opinion of Tax Counsel is
not binding on the Internal Revenue Service (the "IRS") or the courts. No
rulings have been or are expected to be sought from the IRS with respect to any
of the transactions described herein and no assurance can be given that the IRS
will not take contrary positions. Moreover, no assurance can be given that any
of the opinions expressed herein will not be challenged by the IRS or, if
challenged, that such a challenge would not be successful.

EXCHANGE OF CAPITAL SECURITIES

         The exchange of Old Capital Securities for New Capital Securities
should not be a taxable event to holders for United States federal income tax
purposes. The exchange of Old Capital Securities for New Capital Securities
pursuant to the Exchange Offer should not be treated as an "exchange" for United
States federal income tax purposes because the New Capital Securities should not
be considered to differ materially in kind or extent from the Old Capital
Securities and because the exchange will occur by operation of the terms of the
Old Capital Securities. If, however, the exchange of the Old Capital Securities
for the New Capital Securities were treated as an exchange for United States
federal income tax purposes, such exchange should constitute a recapitalization
for federal income tax purposes. Accordingly, the New Capital Securities should
have the same issue price as the Old Capital Securities, and a holder should
have the same adjusted tax basis and holding period in the New Capital
Securities as the holder had in the Old Capital Securities immediately before
the exchange.


                                       65
<PAGE>   67
CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES

         In connection with the issuance of the Old Junior Subordinated
Debentures, Tax Counsel has rendered its opinion generally to the effect that,
under then current law and assuming full compliance with the terms of the
Indenture (and certain other documents), and based on certain facts and
assumptions contained in such opinion, the Old Junior Subordinated Debentures
will be classified for United States federal income tax purposes as indebtedness
of the Corporation. The Corporation, the Trust and the holders of the Capital
Securities (by acceptance of a beneficial interest in a Capital Security) will
agree to treat the Junior Subordinated Debentures as indebtedness for all United
States federal income tax purposes.

CLASSIFICATION OF THE TRUST

         In connection with the issuance of the Old Capital Securities, Tax
Counsel has rendered its opinion generally to the effect that, under then
current law and assuming full compliance with the terms of the Declaration and
the Indenture (and certain other documents), and based on certain facts and
assumptions contained in such opinion, the Trust will be classified for United
States federal income tax purposes as a grantor trust and not as an association
taxable as a corporation. Accordingly, for United States federal income tax
purposes, each holder of Capital Securities generally will be considered the
owner of an undivided interest in the Junior Subordinated Debentures, and each
holder will be required to include in its gross income any interest (or OID
accrued) with respect to its allocable share of those Junior Subordinated
Debentures.

INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT

         Under recently issued Treasury regulations (the "Regulations")
applicable to debt instruments issued on or after August 13, 1996, a "remote"
contingency that stated interest will not be timely paid will be ignored in
determining whether a debt instrument is issued with OID. The Corporation
believes that the likelihood of its exercising its option to defer payments of
interest is "remote" since exercising that option would prevent the Corporation
from declaring dividends on any class of its equity securities. Accordingly, the
Corporation intends to take the position, based on the advice of Tax Counsel,
that the Junior Subordinated Debentures will not be considered to be issued with
OID and, accordingly, stated interest on the Junior Subordinated Debentures
generally will be taxable to a holder as ordinary income at the time it is paid
or accrued in accordance with such holder's method of accounting.

         Under the Regulations, if the Corporation were to exercise its option
to defer payments of interest, the Junior Subordinated Debentures would at that
time be treated as issued with OID, and all stated interest on the Junior
Subordinated Debentures would thereafter be treated as OID as long as the Junior
Subordinated Debentures remain outstanding. In such event, all of a holder's
taxable interest income with respect to the Junior Subordinated Debentures would
thereafter be accounted for on an economic accrual basis regardless of such
holder's method of tax accounting, and actual distributions of stated interest
would not be reported as taxable income. Consequently, a holder of Capital
Securities would be required to include in gross income OID even though the
Corporation would not make actual cash payments during an Extension Period.
Moreover, under the Regulations, if the option to defer the payment of interest
was determined not to be "remote," the Junior Subordinated Debentures would be
treated as having been originally issued with OID. In such event, all of a
holder's taxable interest income with respect to the Junior Subordinated
Debentures would be accounted for on an economic accrual basis regardless of
such holder's method of tax accounting, and actual distributions of stated
interest would not be reported as taxable income.

         The Regulations have not yet been addressed in any rulings or other
interpretations by the IRS, and it is possible that the IRS could take a
position contrary to Tax Counsel's interpretation herein.


                                       66
<PAGE>   68
         Because income on the Capital Securities will constitute interest or
OID, corporate holders of the Capital Securities will not be entitled to a
dividends-received deduction with respect to any income recognized with respect
to the Capital Securities.

RECEIPT OF JUNIOR SUBORDINATED DEBENTURES OR CASH UPON LIQUIDATION OF THE TRUST

         The Corporation will have the right at any time to liquidate the Trust
and cause the Junior Subordinated Debentures to be distributed to the holders of
the Trust Securities. Under current law, such a distribution, for United States
federal income tax purposes, would be treated as a nontaxable event to each
holder, and each holder would receive an aggregate tax basis in the Junior
Subordinated Debentures equal to such holder's aggregate tax basis in its
Capital Securities. A holder's holding period in the Junior Subordinated
Debentures so received in liquidation of the Trust would include the period
during which the Capital Securities were held by such holder. If, however, the
Trust is characterized for United States federal income tax purposes as an
association taxable as a corporation at the time of its dissolution, the
distribution of the Junior Subordinated Debentures may constitute a taxable
event to holders of Capital Securities and a holder's holding period in Junior
Subordinated Debentures would begin on the date such Junior Subordinated
Debentures were received.

         Under certain circumstances described herein (see "Description of New
Securities--Description of New Capital Securities"), the Junior Subordinated
Debentures may be redeemed for cash and the proceeds of such redemption
distributed to holders in redemption of their Capital Securities. Under current
law, such a redemption would, for United States federal income tax purposes,
constitute a taxable disposition of the redeemed Capital Securities, and a
holder could recognize gain or loss as if it sold such redeemed Capital
Securities for cash. See "--Sales of Capital Securities."

SALES OF CAPITAL SECURITIES

         A holder that sells Capital Securities (including a redemption of the
Capital Securities either on the Stated Maturity Date or upon an optional
redemption of the Junior Subordinated Debentures by the Corporation) will
recognize gain or loss equal to the difference between its adjusted tax basis in
the Capital Securities and the amount realized on the sale of such Capital
Securities (other than with respect to accrued and unpaid interest which has not
yet been included in income, which will be treated as ordinary income). A
holder's adjusted tax basis in the Capital Securities generally will be its
initial purchase price increased by OID (if any) previously includable in such
holder's gross income to the date of disposition and decreased by payments (if
any) received on the Capital Securities in respect of OID. Such gain or loss
generally will be a capital gain or loss and generally will be a long-term
capital gain or loss if the Capital Securities have been held for more than one
year.

         The Capital Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Junior Subordinated Debentures. A holder who uses the accrual method of
accounting for tax purposes (and a cash method holder, if the Junior
Subordinated Debentures are deemed to have been issued with OID) who disposes of
his Capital Securities between record dates for payments of distributions
thereon will be required to include accrued but unpaid interest on the Junior
Subordinated Debentures through the date of disposition in income as ordinary
income (i.e., interest or, possibly, OID), and to add such amount to his
adjusted tax basis in his pro rata share of the underlying Junior Subordinated
Debentures deemed disposed of. To the extent the selling price is less than the
holder's adjusted tax basis (which will include all accrued but unpaid
interest), a holder 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.

<PAGE>   69
PROPOSED TAX LEGISLATION

         On February 6, 1997, as part of President Clinton's Fiscal 1998 Budget
Proposal, the United States Treasury Department proposed legislation that would,
among other things, deny an issuer a deduction for United States federal income
tax purposes for the payment of interest on instruments with characteristics
similar to the Junior Subordinated Debentures. If the proposed legislation were
enacted in its current form, it is not expected to apply to the Junior
Subordinated Debentures since the proposed effective date for this provision is
the date of first committee action. There can be no assurances, however, that
the proposed legislation, if enacted, or similar legislation enacted after the
date hereof would not adversely affect the tax treatment of the Junior
Subordinated Debentures, resulting in a Tax Event. The occurrence of a Tax Event
may result in the redemption of the Junior Subordinated Debentures for cash, in
which event the holders of the Capital Securities would receive cash in
redemption of their Capital Securities.

UNITED STATES ALIEN HOLDERS

         For purposes of this discussion, a "United States Alien Holder" is any
corporation, individual, partnership, estate or trust that is not a U.S. Holder
for United States federal income tax purposes.

         A "U.S. Holder" is a holder of Capital Securities who or which is a
citizen or individual resident (or is treated as a citizen or individual
resident) of the United States for federal income tax purposes, a corporation or
partnership created or organized (or treated as created or organized for federal
income tax purposes) in or under the laws of the United States or any political
subdivision thereof, or a trust or estate the income of which is includible in
its gross income for federal income tax purposes without regard to its source.
(For taxable years beginning after December 31, 1996 (or for the immediately
preceding taxable year, if the trustee of a trust so elects), a trust is a U.S.
Holder for federal income tax purposes if, and only if, (i) a court within the
United States is able to exercise primary supervision over the administration of
the trust and (ii) one or more United States trustees have the authority to
control all substantial decisions of the trust.)

         Under present United States federal income tax laws: (i) payments by
the Trust or any of its paying agents to any holder of a Capital Security who or
which is a United States Alien Holder will not be subject to United States
federal withholding tax; provided that, (a) the beneficial owner of the Capital
Security does not actually or constructively own 10 percent or more of the total
combined voting power of all classes of stock of the Corporation entitled to
vote, (b) the beneficial owner of the Capital Security is not a controlled
foreign corporation that is related to the Corporation through stock ownership,
and (c) either (A) the beneficial owner of the Capital Security certifies to the
Trust or its agent, under penalties of perjury, that it is not a United States
holder and provides its name and address or (B) a securities clearing
organization, bank or other financial institution that holds customers'
securities in the ordinary course of its trade or business (a "Financial
Institution"), and holds the Capital Security in such capacity, certifies to the
Trust or its agent, under penalties of perjury, that such statement has been
received from the beneficial owner by it or by a Financial Institution between
it and the beneficial owner and furnishes the Trust or its agent with a copy
thereof; and (ii) a United States Alien Holder of a Capital Security will not be
subject to United States federal withholding tax on any gain realized upon the
sale or other disposition of a Capital Security.

         As discussed above, changes in legislation affecting the United States
federal income tax treatment of the Junior Subordinated Debentures are possible,
and could adversely affect the ability of the Corporation to deduct the interest
payable on the Junior Subordinated Debentures. Moreover, any such legislation
could, as the Proposed Legislation would have, adversely affect United States
Alien Holders by characterizing income derived from the Junior Subordinated
Debentures as dividends, generally subject to a 30% income tax (on a withholding
basis) when paid to a United States Alien Holder, rather than as interest which,
as discussed above, is generally exempt from income tax in the hands of a United
States Alien Holder.


                                       68
<PAGE>   70
         A United States Alien Holder that holds Capital Securities in
connection with the active conduct of a United States trade or business will be
subject to income tax on all income and gains recognized with respect to its
proportionate share of the Junior Subordinated Debentures.

INFORMATION REPORTING TO HOLDERS

         Generally, income on the Capital Securities will be reported to holders
on Forms 1099, which forms should be mailed to holders of Capital Securities by
January 31 following each calendar year.

BACKUP WITHHOLDING

         Payments made on, and proceeds from the sale of, the Capital Securities
may be subject to a "backup" withholding tax of 31 percent unless the holder
complies with certain identification requirements. Any withheld amounts will be
allowed as a credit against the holder's United States federal income tax,
provided the required information is provided to the IRS.

         THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS
INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A
HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE ACQUISITION, OWNERSHIP AND
DISPOSITION OF THE CAPITAL SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER
STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN
UNITED STATES FEDERAL OR OTHER TAX LAWS.


                              ERISA CONSIDERATIONS

         The Corporation, the obligor with respect to the Junior Subordinated
Debentures held by the Trust, and its affiliates and the Property Trustee may be
considered a "party in interest" (within the meaning of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) or a "disqualified person"
(within the meaning of Section 4975 of the Code) with respect to many employee
benefit plans ("Plans") that are subject to ERISA. Any purchaser proposing to
acquire Capital Securities with assets of any Plan should consult with its
counsel. The purchase and/or holding of Capital Securities by a Plan that is
subject to the fiduciary responsibility provisions of ERISA or the prohibited
transaction provisions of Section 4975 of the Code (including individual
retirement arrangements and other plans described in Section 4975(e)(1) of the
Code) and with respect to which the Corporation, the Property Trustee or any
affiliate is a service provider (or otherwise is a party in interest or a
disqualified person) may constitute or result in a prohibited transaction under
ERISA or Section 4975 of the Code, unless such Capital Securities are acquired
pursuant to and in accordance with an applicable exemption, such as Prohibited
Transaction Class Exemption ("PTCE") 84-14 (an exemption for certain
transactions determined by an independent qualified professional asset manager),
PTCE 91-38 (an exemption for certain transactions involving bank collective
investment funds), PTCE 90-1 (an exemption for certain transactions involving
insurance company pooled separate accounts), PTCE 95-60 (an exemption for
transactions involving certain insurance company general accounts) or PTCE 95-23
(an exemption for certain transactions determined by an in-house manager). In
addition, as described below, a Plan fiduciary considering the acquisition of
Capital Securities should be aware that the assets of the Trust may be
considered "plan assets" for ERISA purposes. In such event, service providers
with respect to the assets of the Trust may become parties in interest or
disqualified persons with respect to investing Plans, and any discretionary
authority exercised with respect to the Junior Subordinated Debentures by such
persons could be deemed to constitute a prohibited transaction under ERISA or
the Code. In order to avoid such prohibited transactions, each investing Plan,
by acquiring the Capital Securities, will be deemed to have directed the Trust
to invest in the Junior Subordinated Debentures and to have appointed the
Property Trustee.


                                       69
<PAGE>   71
         A Plan fiduciary should consider whether the acquisition of Capital
Securities could result in a delegation of fiduciary authority to the Property
Trustee, and, if so, whether such a delegation of authority is permissible under
the Plan's governing instrument or any investment management agreement with the
Plan. In making such determination, a Plan fiduciary should note that the
Property Trustee is a U.S. bank qualified to be an investment manager (within
the meaning of section 3(38) of ERISA) to which such a delegation of authority
generally would be permissible under ERISA. Further, prior to an Event of
Default with respect to the Junior Subordinated Debentures, the Property Trustee
will have only limited custodial and ministerial authority with respect to Trust
assets.

         Under the U.S. Department of Labor regulations defining "plan assets"
for ERISA purposes (the "Plan Assets Regulations"), the assets of the Trust will
be considered plan assets of Plans owning Capital Securities unless the
aggregate investment in Capital Securities by "benefit plan investors" is not
deemed "significant" or another exception in the Plan Assets Regulations was
applicable. For this purpose, equity participation by benefit plan investors
will not be considered "significant" on any date only if, immediately after the
most recent acquisition of Capital Securities, the aggregate interest in the
Capital Securities held by benefit plan investors will be less than 25% of the
value of the Capital Securities. Although it is possible that the equity
participation by benefit plan investors in Capital Securities on any date will
not be "significant" for purposes of the Plan Assets Regulations, such result
cannot be assured.


                              PLAN OF DISTRIBUTION

         Each broker-dealer that receives New Capital Securities for its own
account in connection with the Exchange Offer must acknowledge that it will
deliver a prospectus in connection with any resale of such New Capital
Securities. This Prospectus, as it may be amended or supplemented from time to
time, may be used by Participating Broker-Dealers during the period referred to
below in connection with resales of New Capital Securities received in exchange
for Old Capital Securities if such Old Capital Securities were acquired by such
Participating Broker-Dealers for their own accounts as a result of market-making
activities or other trading activities. The Corporation and the Trust have
agreed that this Prospectus, as it may be amended or supplemented from time to
time, may be used by a Participating Broker-Dealer in connection with resales of
such New Capital Securities for a period ending 90 days after the Expiration
Date (subject to extension under certain limited circumstances described herein)
or, if earlier, when all such New Capital Securities have been disposed of by
such Participating Broker-Dealer. However, a Participating Broker-Dealer who
intends to use this Prospectus in connection with the resale of New Capital
Securities received in exchange for Old Capital Securities pursuant to the
Exchange Offer must notify the Corporation or the Trust, or cause the
Corporation or the Trust to be notified, on or prior to the Expiration Date,
that it is a Participating Broker-Dealer. Such notice may be given in the space
provided for that purpose in the Letter of Transmittal or may be delivered to
the Exchange Agent at one of the addresses set forth herein under "The Exchange
Offer--Exchange Agent." See "The Exchange Offer--Resales of New Capital
Securities."

         The Corporation or the Trust will not receive any cash proceeds from
the issuance of the New Capital Securities offered hereby. New Capital
Securities received by broker-dealers for their own accounts in connection with
the Exchange Offer may be sold from time to time in one or more transactions in
the over-the-counter market, in negotiated transactions, through the writing of
options on the New Capital Securities or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or at negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such New Capital Securities.

         Any broker-dealer that resells New Capital Securities that were
received by it for its own account in connection with the Exchange Offer and any
broker or dealer that participates in a distribution of such New


                                       70
<PAGE>   72
Capital Securities may be deemed to be an "underwriter" within the meaning of
the Securities Act, and any profit on any such resale of New Capital Securities
and any commissions or concessions received by any such persons may be deemed to
be underwriting compensation under the Securities Act. The Letter of Transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.


                           VALIDITY OF NEW SECURITIES

         Certain matters of Delaware law relating to the validity of the New
Capital Securities and the creation of the Trust will be passed upon on behalf
of the Trust by Richards, Layton & Finger, P.A. special Delaware counsel to the
Trust and the Corporation. The validity of the New Guarantee and the New Junior
Subordinated Debentures will be passed upon for the Corporation by Elias, Matz,
Tiernan & Herrick L.L.P., Washington, D.C. Certain matters relating to United
States federal income tax considerations will be passed upon for the Corporation
by Elias, Matz, Tiernan & Herrick L.L.P., Washington, D.C.


                                     EXPERTS

         The audited consolidated financial statements of the Corporation
incorporated by reference herein have been incorporated by reference herein in
reliance upon the report of KPMG Peat Marwick LLP, independent certified public
accountants, and upon the authority of said firm as experts in accounting and
auditing.

                                     PART II

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 719 of the Maine Business Corporation Act ("MBCA") sets forth
certain circumstances under which directors, officers, employees and agents may
be indemnified against liability which they may incur in their capacity as such.
Indemnification may be provided against expenses, including attorneys' fees,
judgments, fines and amounts paid in settlement actually and reasonably
incurred; provided that no indemnification may be provided with respect to any
matter where such person shall have been finally adjudicated (i) not to have
acted honestly or in the reasonable belief that such action was in or not
opposed to the best interests of the corporation or its shareholders, or (ii)
with respect to any criminal action, to have had reasonable cause to believe
such conduct was unlawful. A corporation may not indemnify a person with respect
to any action or matter by or in the right of the corporation as to which that
person is finally adjudicated to be liable to the corporation unless the court
in which the action was brought determines that, in view of all the
circumstances, that person is fairly and reasonably entitled to indemnity for
such amounts as the court deems reasonable. To the extent such person has been
successful on the merits or otherwise in defense of such action, that person
shall be entitled to indemnification. Any indemnification, unless ordered by a
court or required in the corporation's bylaws, shall be made only as authorized
in the specific case upon a determination by the board of directors that
indemnification is proper in the circumstances and in the best interests of the
corporation. Expenses incurred in defending an action may be paid by the
corporation in advance of the final disposition of that action upon a
determination made that the person seeking indemnification satisfied the
standard of conduct required for indemnification and receipt by the corporation
of a written undertaking by or on behalf of such person to repay that amount if
that person is finally adjudicated to not have met such standard or not be
entitled to such indemnification. In addition, Section 719 of the MBCA provides
that a corporation may purchase and maintain insurance on behalf of directors,
officers, employees and agents against liability whether or not the corporation
would have the power to indemnify such person against liability under such
section. See Title 13-A Maine Revised Statutes Annotated Section 719.

         Article VI of the Bylaws of the Corporation provides that the
directors, officers, employees and agents of the Corporation shall be
indemnified to the full extent permitted by the MBCA. Such indemnity shall
extend to expenses, including attorney's fees, judgments, fines and amounts paid
in the settlement, prosecution or defense of the foregoing actions. Directors
and officers also may be indemnified pursuant to the terms of various employee
benefit plans of the Corporation. In addition, the Corporation carries a
liability insurance policy for its directors and officers.

ITEM 22. UNDERTAKINGS

         Each of the undersigned Registrants hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, as
amended, each filing of a Registrant's annual report pursuant to Section 13(a)
or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

         Each of the undersigned Registrants hereby also undertakes:


                                      II-2
<PAGE>   75
         (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;

                  (ii) to reflect in the prospectus any facts or events arising
         after the effective date of this Registration Statement (or the most
         recent post-effective amendment thereto) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in this Registration Statement. 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 percent change
         in the maximum aggregate offering price set forth in the "Calculation
         of Registration Fee" table in the effective Registration Statement; and

                  (iii) to include any material information with respect to the
         plan of distribution not previously disclosed in this Registration
         Statement or any material change to such information in this
         Registration Statement; provided, however, that paragraphs (1)(i) and
         (1)(ii) do not apply if the information required to be included in a
         post-effective amendment by those paragraphs is contained in periodic
         reports filed by a Registrant pursuant to Section 13 or Section 15(d)
         of the Securities Exchange Act of 1934 that are incorporated by
         reference in this 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.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
each undersigned Registrant pursuant to the provisions, 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 undersigned Registrant
of expenses incurred or paid by a director, officer of 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 the 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.

         Each of the undersigned Registrants hereby undertakes to respond to
requests for information that is incorporated by reference into the Prospectus
pursuant to Item 4, 10(b), 11 or 13 of this Form within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.

         Each of the undersigned Registrants hereby undertakes to supply by
means of a post-effective amendment all information concerning a transaction,
and the company being acquired or involved therein, that was not the subject of
and included in the registration statement when it became effective.

                                   SECURITIES

            SECTION 2.01.     Forms Generally.

            The Securities and the Trustee's certificate of authentication shall
be substantially in the form of Exhibit A, the terms of which are incorporated
in and made a part of this Indenture. The Securities may have notations, legends
or endorsements required by law, stock exchange rule, agreements to which the
Corporation is subject or usage. Each Security shall be dated the date of its
authentication. The Securities shall be issued in denominations of $100,000 and
integral multiples of $1,000 in excess thereof.

            SECTION 2.02.     Execution and Authentication.

            Two Officers shall sign the Securities for the Corporation by manual
or facsimile signature in the manner set forth in Exhibit A. If an Officer whose
signature is on a Security no longer holds that office at the time the Security
is authenticated, the Security shall nevertheless be valid.

signature of an authorized signatory of the Trustee. The signature of the
Trustee shall be conclusive evidence that the Security has been authenticated
under this Indenture. The form of Trustee's certificate of authentication to be
borne by the Securities shall be substantially as set forth in Exhibit A hereto.

            The Trustee shall, upon a Corporation Order, authenticate for
original issue up to, and the aggregate principal amount of Securities

be the Series A Securities.

            SECTION 2.03.     Form and Payment.

            Except as provided in Section 2.05, the Securities shall be issued
in fully registered certificated form without interest coupons. Principal of,
premium, if any, and interest on the Securities issued in certificated form will
be payable, the transfer of such Securities will be registrable and such
Securities will be exchangeable for Securities bearing identical terms and
provisions at the office or agency of the Corporation maintained for such
purpose under Section 3.02; provided, however, that payment of interest with
respect to the Securities may be made at the option of the Corporation (i) by
check mailed to the holder at such address as shall appear in the Security
Register or (ii) by wire transfer to an account maintained by the Person
entitled


                                       14
<PAGE>   23
thereto, provided that proper wire transfer instructions have been received in
writing by the relevant record date. Notwithstanding the foregoing, so long as
the holder of any Securities is the Property Trustee, the payment of the
principal of, premium, if any, and interest (including Compounded Interest and
Additional Interest, if any) on such Securities held by the Property Trustee
will be made at such place and to such account as may be designated by the
Property Trustee.

            SECTION 2.04.     Legends.

            (a) Except as permitted by subsection (b) of this Section 2.04 or as
otherwise determined by the Corporation in accordance with applicable law, each
Security shall bear the applicable legends relating to restrictions on transfer
pursuant to the securities laws in substantially the form set forth on Exhibit A
hereto.

            (b) The Corporation shall issue and the Trustee shall authenticate
Series B Securities in exchange for Series A Securities accepted for exchange in
the Exchange Offer, which Series B Securities shall not bear the legends
required by subsection (a) above, in each case unless the holder of such Series
A Securities is either (A) a broker-dealer who purchased such Series A
Securities directly from the Corporation for resale pursuant to Rule 144A or any
other available exemption under the Securities Act, (B) a Person participating
in the distribution of the Series A Securities or (C) a Person who is an
affiliate (as defined in Rule 144 under the Securities Act) of the Corporation.

            SECTION 2.05.     Global Security.

            (a)  In connection with a Dissolution Event,

                  (i) if any Capital Securities are held in book-entry form, the
      related Definitive Securities shall be presented to the Trustee (if an
      arrangement with the Depositary has been maintained) by the Property
      Trustee in exchange for one or more Global Securities (as may be required
      pursuant to Section 2.07) in an aggregate principal amount equal to the
      aggregate principal amount of all outstanding Securities, to be registered
      in the name of the Depositary, or its nominee, and delivered by the
      Trustee to the Depositary for crediting to the accounts of its
      participants pursuant to the instructions of the Administrative Trustees;
      the Corporation upon any such presentation shall execute one or more
      Global Securities in such aggregate principal amount and deliver the same
      to the Trustee for authentication and delivery in accordance with this
      Indenture; and payments on the Securities issued as a Global Security will
      be made to the Depositary; and


                                       15
<PAGE>   24
                  (ii) if any Capital Securities are held in certificated form,
      the related Definitive Securities may be presented to the Trustee by the
      Property Trustee and any Capital Security certificate which represents
      Capital Securities other than Capital Securities in book-entry form ("Non
      Book-Entry Capital Securities") will be deemed to represent beneficial
      interests in Securities presented to the Trustee by the Property Trustee
      having an aggregate principal amount equal to the aggregate liquidation
      amount of the Non Book-Entry Capital Securities until such Capital
      Security certificates are presented to the Security Registrar for transfer
      or reissuance, at which time such Capital Security certificates will be
      cancelled and a Security, registered in the name of the holder of the
      Capital Security certificate or the transferee of the holder of such
      Capital Security certificate, as the case may be, with an aggregate
      principal amount equal to the aggregate liquidation amount of the Capital
      Security certificate cancelled, will be executed by the Corporation and
      delivered to the Trustee for authentication and delivery in accordance
      with the Indenture. Upon the issuance of such Securities, Securities with
      an equivalent aggregate principal amount that were presented by the
      Property Trustee to the Trustee will be deemed to have been cancelled.

            (b) The Global Securities shall represent the aggregate amount of
outstanding Securities from time to time endorsed thereon; provided, that the
aggregate amount of outstanding Securities represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of a Global Security to reflect the amount of any
increase or decrease in the amount of outstanding Securities represented thereby
shall be made by the Trustee, in accordance with instructions given by the
Corporation as required by this Section 2.05.

            (c) The Global Securities may be transferred, in whole but not in
part, only to the Depositary, another nominee of the Depositary, or to a
successor Depositary selected or approved by the Corporation or to a nominee of
such successor Depositary.

            (d) If at any time the Depositary notifies the Corporation that it
is unwilling or unable to continue as Depositary or the Depositary has ceased to
be a clearing agency registered under the Exchange Act, and a successor
Depositary is not appointed by the Corporation within 90 days after the
Corporation receives such notice or becomes aware of such condition, as the case
may be, the Corporation will execute, and the Trustee, upon written notice from
the Corporation, will authenticate and make available for delivery the
Definitive Securities, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global Security in
exchange for such Global Security. If there is an Event of Default, the
Depositary shall have the right to


                                       16
<PAGE>   25
exchange the Global Securities for Definitive Securities. In addition, the
Corporation may at any time determine that the Securities shall no longer be
represented by a Global Security. In the event of such an Event of Default or
such a determination, the Corporation shall execute, and subject to Section
2.07, the Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Corporation, will authenticate and make available for
delivery the Definitive Securities, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Security
in exchange for such Global Security. Upon the exchange of the Global Security
for such Definitive Securities, in authorized denominations, the Global Security
shall be cancelled by the Trustee. Such Definitive Securities issued in exchange
for the Global Security shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Definitive Securities to the Depositary for delivery to the
Persons in whose names such Definitive Securities are so registered.

            SECTION 2.06      Interest.

            (a) Each Security will bear interest at the rate of 9.06% per annum
(the "Coupon Rate") from the most recent date to which interest has been paid or
duly provided for or, if no interest has been paid or duly provided for, from
the Issue Date, until the principal thereof becomes due and payable, and at the
Coupon Rate on any overdue principal (and premium, if any) and (to the extent
that payment of such interest is enforceable under applicable law) on any
overdue installment of interest, compounded semi-annually, payable (subject to
the provisions of Article XVI) semi-annually in arrears on February 1 and August
1 of each year (each, an "Interest Payment Date") commencing on August 1, 1997,
to the Person in whose name such Security or any predecessor Security is
registered, at the close of business on the regular record date for such
interest installment, which shall be the fifteenth day of the month which
precedes the month in which the relevant Interest Payment Date falls.

            (b) Interest will be computed on the basis of a 360-day year
consisting of twelve 30-day months and, for any period of less than a full
calendar month, the number of days lapsed in such month. In the event that any
Interest Payment Date falls on a day that is not a Business Day, then payment of
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), with the same force and effect as if made on such date.

            (c) During such time as the Property Trustee is the holder of any
Securities, the Corporation shall pay any additional amounts on the Securities
as may be necessary in order that the


                                       17
<PAGE>   26
amount of Distributions then due and payable by the Peoples Heritage Capital
Trust on the outstanding Securities shall not be reduced as a result of any
additional taxes, duties and other governmental charges to which the Peoples
Heritage Capital Trust has become subject as a result of a Tax Event
("Additional Interest").

            SECTION 2.07.     Transfer and Exchange.

            (a) Transfer Restrictions. The Series A Securities, and those Series
B Securities with respect to which any Person described in Section 2.04(b)(A),
(B) or (C) is the beneficial owner, may not be transferred except in compliance
with the legend contained in Exhibit A unless otherwise determined by the
Corporation in accordance with applicable law. Upon any distribution of the
Securities following a Dissolution Event, the Corporation and the Trustee shall
enter into a supplemental indenture pursuant to Section 9.01 to provide for the
transfer restrictions and procedures with respect to the Securities
substantially similar to those contained in the Declaration to the extent
applicable in the circumstances existing at such time.

            (b) General Provisions Relating to Transfers and Exchanges. Upon
surrender for registration of transfer of any Security at the office or agency
of the Corporation maintained for the purpose pursuant to Section 3.02, the
Corporation shall execute, and the Trustee shall authenticate and make available
for delivery, in the name of the designated transferee or transferees, one or
more new Securities of the same series, of any authorized denominations and of a
like aggregate principal amount.

            At the option of the holder, Securities of any series may be
exchanged for other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Corporation shall execute, and the Trustee
shall authenticate and make available for delivery, the Securities which the
holder making the exchange is entitled to receive.

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

            All Definitive Securities and Global Securities issued upon any
registration of transfer or exchange of Definitive Securities or Global
Securities shall be the valid obligations of the Corporation, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the
Definitive Securities or


                                       18
<PAGE>   27
Global Securities surrendered upon such registration of transfer or exchange.

            No service charge shall be made to a holder for any registration of
transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in
connection therewith.

            The Corporation shall not be required to (i) issue, register the
transfer of or exchange Securities during a period beginning at the opening of
business 15 days before the day of mailing of a notice of redemption or any
notice of selection of Securities for redemption under Article XIV hereof and
ending at the close of business on the day of such mailing; or (ii) register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

            (c)  Exchange of Series A Securities for Series B Securi-
ties.  The Series A Securities may be exchanged for Series B
Securities pursuant to the terms of the Exchange Offer.  The
Trustee shall make the exchange as follows:

            The Corporation shall present the Trustee with an Officers'
Certificate certifying the following:

            (A)   upon issuance of the Series B Securities, the transactions
                  contemplated by the Exchange Offer have been consummated; and

            (B)   the principal amount of Series A Securities prop-
                  erly tendered in the Exchange Offer that are repre-
                  sented by a Global Security and the principal
                  amount of Series A Securities properly tendered in
                  the Exchange Offer that are represented by Defin-
                  itive Securities, the name of each holder of such
                  Definitive Securities, the principal amount prop-
                  erly tendered in the Exchange Offer by each such
                  holder and the name and address to which Definitive
                  Securities for Series B Securities shall be
                  registered and sent for each such holder.

            The Trustee, upon receipt of (i) such Officers' Certificate, (ii) an
Opinion of Counsel (x) to the effect that the Series B Securities have been
registered under Section 5 of the Securities Act and the Indenture has been
qualified under the Trust Indenture Act and (y) with respect to the matters set
forth in Section 3(o) of the Registration Rights Agreement and (iii) a
Corporation Order, shall authenticate (A) a Global Security for Series B
Securities in aggregate principal amount equal to the aggregate principal amount
of Series A Securities represented by a Global Security indicated in such
Officers' Certificate as having been properly tendered and


                                       19
<PAGE>   28
(B) Definitive Securities representing Series B Securities registered in the
names of, and in the principal amounts indicated in, such Officers' Certificate.

            If the principal amount of the Global Security for the Series B
Securities is less than the principal amount of the Global Security for the
Series A Securities, the Trustee shall make an endorsement on such Global
Security for Series A Securities indicating a reduction in the principal amount
represented thereby.

            The Trustee shall make such Definitive Securities for Series B
Securities available for delivery to the holders thereof as indicated in such
Officers' Certificate.

            SECTION 2.08.     Replacement Securities.

            If any mutilated Security is surrendered to the Trustee, or the
Corporation and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, the Corporation shall issue and the
Trustee shall authenticate a replacement Security if the Trustee's requirements
for replacements of Securities are met. An indemnity bond must be supplied by
the holder that is sufficient in the judgment of the Trustee and the Corporation
to protect the Corporation, the Trustee, any agent thereof or any authenticating
agent from any loss that any of them may suffer if a Security is replaced. The
Corporation or the Trustee may charge for its expenses in replacing a Security.

            Every replacement Security is an obligation of the Corporation and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with 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
of mutilated, destroyed, lost or stolen Securities.

            SECTION 2.09.     [Intentionally Omitted]

            SECTION 2.10.     Temporary Securities.

            Pending the preparation of definitive Securities, the Corporation
may execute, and upon Corporation Order the Trustee shall authenticate and make
available for delivery, temporary Securities that are printed, lithographed,
typewritten, mimeographed or otherwise reproduced, in any authorized
denomination, substantially of the tenor of the definitive Securities 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 conclusively evidenced by their execution of such Securities.


                                       20
<PAGE>   29
            If temporary Securities are issued, the Corporation shall cause
definitive Securities to be prepared without unreasonable delay. The definitive
Securities shall be printed, lithographed or engraved, or provided by any
combination thereof, or in any other manner permitted by the rules and
regulations of any applicable securities exchange, all as determined by the
officers executing such definitive Securities. 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 maintained by the Corporation for such purpose pursuant to Section
3.02 hereof, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities, the Corporation shall execute, and the
Trustee shall authenticate and make available for delivery, in exchange therefor
the same aggregate principal amount of definitive Securities of authorized
denominations. Until so exchanged, the temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

            SECTION 2.11.     Cancellation.

            The Corporation at any time may deliver Securities to the Trustee
for cancellation. The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall retain or dispose of cancelled Securities in accordance
with its normal practices (subject to the record retention requirement of the
Exchange Act) unless the Corporation directs them to be returned to it. The
Corporation may not issue new Securities to replace Securities that have been
redeemed or paid or that have been delivered to the Trustee for cancellation.

            SECTION 2.12.     Defaulted Interest.

            Any interest on any Security that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the holder on the
relevant regular record date by virtue of having been such holder; and such
Defaulted Interest shall be paid by the Corporation, at its election, as
provided in clause (a) or clause (b) below:

            (a) The Corporation may make payment of any Defaulted Interest on
      Securities to the Persons in whose names such Securities (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 Corporation shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each such Security and the date of the proposed payment, and at the
      same time the Corporation shall deposit with the Trustee an amount of
      money equal to the


                                       21
<PAGE>   30
      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 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
      not be more than 15 nor 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 Corporation of such special record date and, in the name and at
      the expense of the Corporation, 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 Securityholder at his or her
      address as it appears in the Security Register, not less than 10 days
      prior to 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 such Securities (or their respective Predecessor Securities)
      are registered on such special record date and shall be no longer payable
      pursuant to the following clause (b).

            (b) The Corporation may make payment of any Defaulted Interest on
      any Securities in any other lawful manner not inconsistent with the
      requirements of any securities exchange on which such Securities may be
      listed, and upon such notice as may be required by such exchange, if,
      after notice given by the Corporation to the Trustee of the proposed
      payment pursuant to this clause, such manner of payment shall be deemed
      practicable by the Trustee.

            SECTION 2.13.     CUSIP Numbers.

            The Corporation 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 Securityholders; 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. The Corporation will promptly
notify the Trustee of any change in the CUSIP numbers.


                                   ARTICLE III

                    PARTICULAR COVENANTS OF THE CORPORATION

            SECTION 3.01.     Payment of Principal, Premium and
                              Interest.

            The Corporation covenants and agrees for the benefit of the holders
of the Securities that it will duly and punctually pay or cause to be paid the
principal of and premium, if any, and interest on the Securities at the place,
at the respective times and in the manner provided herein. Except as provided in
Section 2.03, each installment of interest on the Securities may be paid by
mailing checks for such interest payable to the order of the holder of Security
entitled thereto as they appear in the Security Register. The Corporation
further covenants to pay any and all amounts including, without limitation,
Liquidated Damages, if any, on the dates and in the manner required under the
Registration Rights Agreement.

            SECTION 3.02.     Offices for Notices and Payments, etc.

            So long as any of the Securities remain outstanding, the Corporation
will maintain in the Borough of Manhattan, The City of New York, an office or
agency where the Securities may be presented for payment, an office or agency
where the Securities may be presented for registration of transfer and for
exchange as in this Indenture provided and an office or agency where notices and
demands to or upon the Corporation in respect of the Securities or of this
Indenture may be served. The Corporation will give to the Trustee written notice
of the location of any such office or agency and of any change of location
thereof. Until otherwise designated from time to time by the Corporation in a
notice to the Trustee, any such office or agency for all of the above purposes
shall be the Principal Office of the Trustee. In case the Corporation shall fail
to maintain any such office or agency in the Borough of Manhattan, The City of
New York, or shall fail to give such notice


                                       23
<PAGE>   32
of the location or of any change in the location thereof, presentations and
demands may be made and notices may be served at the Principal Office of the
Trustee.

            In addition to any such office or agency, the Corporation may from
time to time designate one or more offices or agencies outside the Borough of
Manhattan, The City of New York, where the Securities may be presented for
payment, registration of transfer and for exchange in the manner provided in
this Indenture, and the Corporation may from time to time rescind such
designation, as the Corporation may deem desirable or expedient; provided,
however, that no such designation or rescission shall in any manner relieve the
Corporation of its obligation to maintain any such office or agency in the
Borough of Manhattan, The City of New York, for the purposes above mentioned.
The Corporation will give to the Trustee prompt written notice of any such
designation or rescission thereof.

            SECTION 3.03.     Appointments to Fill Vacancies in
                              Trustee's Office.

            The Corporation, whenever necessary to avoid or fill a vacancy in
the office of Trustee, will appoint, in the manner provided in Section 6.10, a
Trustee, so that there shall at all times be a Trustee hereunder.

            SECTION 3.04.     Provision as to Paying Agent.

            (a)   If the Corporation shall appoint a paying agent other than the
                  Trustee with respect to the Securities, it will cause such
                  paying agent to execute and deliver to the Trustee an
                  instrument in which such agent shall agree with the Trustee,
                  subject to the provision of this Section 3.04,

                  (1)   that it will hold all sums held by it as such agent for
                        the payment of the principal of and premium, if any, or
                        interest on the Securities (whether such sums have been
                        paid to it by the Corporation or by any other obligor on
                        the Securities of such series) in trust for the benefit
                        of the holders of the Securities;

                  (2)   that it will give the Trustee notice of any failure by
                        the Corporation (or by any other obligor on the
                        Securities) to make any payment of the principal of and
                        premium or interest on the Securities when the same
                        shall be due and payable; and

                  (3)   that it will at any time during the continuance of any
                        such failure, upon the written


                                       24
<PAGE>   33
                        request of the Trustee, forthwith pay to the Trustee 
                        all sums so held in trust by it as such paying agent.

            (b)   If the Corporation shall act as its own paying agent, it will,
                  on or before each due date of the principal of and premium, if
                  any, or interest on the Securities, set aside, segregate and
                  hold in trust for the benefit of the holders of the Securities
                  a sum sufficient to pay such principal, premium or interest so
                  becoming due and will notify the Trustee of any failure to
                  take such action and of any failure by the Corporation (or by
                  any other obligor under the Securities) to make any payment of
                  the principal of and premium, if any, or interest on the
                  Securities when the same shall become due and payable.

            (c)   Anything in this Section 3.04 to the contrary
                  notwithstanding, the Corporation may, at any time,
                  for the purpose of obtaining a satisfaction and
                  discharge with respect to the Securities hereunder,
                  or for any other reason, pay or cause to be paid to
                  the Trustee all sums held in trust for any such
                  series by the Trustee or any paying agent hereun-
                  der, as required by this Section 3.04, such sums to
                  be held by the Trustee upon the trusts herein
                  contained.

            (d)   Anything in this Section 3.04 to the contrary notwithstanding,
                  the agreement to hold sums in trust as provided in this
                  Section 3.04 is subject to Sections 11.03 and 11.04.

            SECTION 3.05.     Certificate to Trustee.

            The Corporation will deliver to the Trustee on or before 120 days
after the end of each fiscal year in each year, commencing with the first fiscal
year ending after the date hereof, so long as Securities are outstanding
hereunder, an Officers' Certificate, one of the signers of which shall be the
principal executive, principal financial or principal accounting officer of the
Corporation stating that in the course of the performance by the signers of
their duties as officers of the Corporation they would normally have knowledge
of any default by the Corporation in the performance of any covenants contained
herein, stating whether or not they have knowledge of any such default and, if
so, specifying each such default of which the signers have knowledge and the
nature thereof.

in order to avoid the issuance of fractional shares of capital stock following a
reclassification of the Corporation's capital stock or the exchange or the
conversion of one class or series of the Corporation's capital stock for another
class or series of the Corporation's capital stock; (e) the purchase of
fractional interests in shares of the Corporation's capital stock pursuant to

Corporation has actual knowledge that (a) is, or with the giving of notice or
the lapse of time, or both, would constitute an Event of Default and (b) in

be in default with respect to its payment obligations under the Capital

the Trust Securities of Peoples Heritage Capital Trust or certain mergers,
consolidations or amalgamations, each as permitted by the Declaration of Peoples
Heritage Capital Trust, and (b) to otherwise continue to be treated as a grantor
trust and not an association taxable as a corporation for United States federal

                           CORPORATION AND THE TRUSTEE

            SECTION 4.01.     Securityholders' Lists.

            The Corporation covenants and agrees that it will furnish or cause
to be furnished to the Trustee:

            (a)   on a semi-annual basis on each regular record date for the
                  Securities, a list, in such form as the Trustee may reasonably
                  require, of the names and addresses of the Securityholders as
                  of such record date; and

            (b)   at such other times as the Trustee may request in writing,
                  within 30 days after the receipt by the Corporation, of any
                  such request, a list of similar form and content as of a date
                  not more than 15 days prior to the time such list is
                  furnished,

            except that, no such lists need be furnished so long as the Trustee
            is in possession thereof by reason of its acting as Security
            registrar.

            SECTION 4.02. Preservation and Disclosure of Lists.

            (a)   The Trustee shall preserve, in as current a form as is
                  reasonably practicable, all information as to the names and
                  addresses of the holders of the Securities (1) contained in
                  the most recent list furnished to it as provided in Section
                  4.01 or (2) received by it in the capacity of Securities reg-

                  and furnish to the Trustee reasonable proof that each such
                  applicant has owned a Security for a period of at least six
                  months preceding the date of such application, and such
                  application states that the applicants desire to

<PAGE>   38
                  communicate with other holders of Securities or with holders
                  of all Securities with respect to their rights under this
                  Indenture and is accompanied by a copy of the form of proxy
                  or other communication which such applicants propose to
                  transmit, then the Trustee shall within 5 Business Days
                  after the receipt of such application, at its election,
                  either:

            (1)   afford such applicants access to the information preserved at
                  the time by the Trustee in accordance with the provisions of
                  subsection (a) of this Section 4.02, or

            (2)   inform such applicants as to the approximate number of holders
                  of all Securities, whose names and addresses appear in the
                  information preserved at the time by the Trustee in accordance
                  with the provisions of subsection (a) of this Section 4.02,
                  and as to the approximate cost of mailing to such
                  Securityholders the form of proxy or other communication, if
                  any, specified in such application.

                        If the Trustee shall elect not to afford such applicants
                  access to such information, the Trustee shall, upon the
                  written request of such applicants, mail to each
                  Securityholder whose name and address appear in the
                  information preserved at the time by the Trustee in accordance
                  with the provisions of subsection (a) of this Section 4.02 a
                  copy of the form of proxy or other communication which is
                  specified in such request with reasonable promptness after a
                  tender to the Trustee of the material to be mailed and of
                  payment, or provision for the payment, of the reasonable
                  expenses of mailing, unless within five days after such
                  tender, the Trustee shall mail to such applicants and file
                  with the Commission, together with a copy of the material to
                  be mailed, a written statement to the effect that, in the
                  opinion of the Trustee, such mailing would be contrary to the
                  best interests of the holders of Securities of such series or
                  all Securities, as the case may be, or would be in violation
                  of applicable law. Such written statement shall specify the
                  basis of such opinion. If the Commission, after opportunity
                  for a hearing upon the objec-

                  tions specified in the written statement so filed, shall enter
                  an order refusing to sustain any of such objections or if,
                  after the entry of an order sustaining one or more of such
                  objections, the Commission shall find, after notice and
                  opportunity for hearing, that all the objections so sustained
                  have been met and shall enter an order so declaring, the
                  Trustee shall mail copies of such material to all such
                  Securityholders with reasonable promptness after the entry of
                  such order and the renewal of such tender; otherwise the
                  Trustee shall be relieved of any obligation or duty to such
                  applicants respecting their application.

            (c)   Each and every holder of Securities, by receiving
                  and holding the same, agrees with the Corporation
                  and the Trustee that neither the Corporation nor
                  the Trustee nor any paying agent shall be held ac-
                  countable by reason of the disclosure of any such
                  information as to the names and addresses of the
                  holders of Securities in accordance with the pro-
                  visions of subsection (b) of this Section 4.02,
                  regardless of the source from which such informa-
                  tion was derived, and that the Trustee shall not be
                  held accountable by reason of mailing any material
                  pursuant to a request made under said subsection
                  (b).

            SECTION 4.03. Reports by Corporation.

            (a)   The Corporation covenants and agrees to file with
                  the Trustee, within 15 days after the date on which
                  the Corporation is required to file the same with
                  the Commission, copies of the annual reports and of
                  the information, documents and other reports (or
                  copies of such portions of any of the foregoing as
                  said Commission may from time to time by rules and
                  regulations prescribe) which the Corporation may be
                  required to file with the Commission pursuant to
                  Section 13 or Section 15(d) of the Exchange Act;
                  or, if the Corporation is not required to file in-
                  formation, documents or reports pursuant to either
                  of such sections, then to file with the Trustee and
                  the Commission, in accordance with rules and regu-
                  lations prescribed from time to time by the Commis-
                  sion, such of the supplementary and periodic in-
                  formation, documents and reports which may be
                  required pursuant to Section 13 of the Exchange Act
                  in respect of a security listed and registered on a
                  national securities exchange as may be prescribed
                  from time to time in such rules and regulations.

            (b)   The Corporation covenants and agrees to file with
                  the Trustee and the Commission, in accordance with
                  the rules and regulations prescribed from time to
                  time by said Commission, such additional informa-
                  tion, documents and reports with respect to com-
                  pliance by the Corporation with the conditions and


                                       31
<PAGE>   40
                  covenants provided for in this Indenture as may be
                  required from time to time by such rules and regu-
                  lations.

            (c)   The Corporation covenants and agrees to transmit by mail to
                  all holders of Securities, as the names and addresses of such
                  holders appear upon the Security Register, within 30 days
                  after the filing thereof with the Trustee, such summaries of
                  any information, documents and reports required to be filed by
                  the Corporation pursuant to subsections (a) and
                  (b) of this Section 4.03 as may be required by rules and
                  regulations prescribed from time to time by the Commission.

            (d)   Delivery of such reports, information and documents
                  to the Trustee is for informational purposes only
                  and the Trustee's receipt of such shall not
                  constitute constructive notice of any information
                  contained therein or determinable from information
                  contained therein, including the Corporation's
                  compliance with any of its covenants hereunder (as
                  to which the Trustee is entitled to rely exclu-
                  sively on Officers' Certificates).

            (e)   So long as is required for an offer or sale of the
                  Securities to qualify for an exemption under Rule
                  144A under the Securities Act, the Corporation
                  shall, upon request, provide the information re-
                  quired by clause (d)(4) thereunder to each Holder
                  and to each beneficial owner and prospective pur-
                  chaser of Securities identified by any holder of
                  Restricted Securities, unless such information is
                  furnished to the Commission pursuant to Section 13
                  or 15(d) of the Exchange Act.

            SECTION 4.04. Reports by the Trustee.

            (a)   The Trustee shall transmit to Securityholders such
                  reports concerning the Trustee and its actions
                  under this Indenture as may be required pursuant to
                  the Trust Indenture Act at the times and in the
                  manner provided pursuant thereto.  If required by
                  Section 313(a) of the Trust Indenture Act, the
                  Trustee shall, within sixty days after each May 15
                  following the date of this Indenture, commencing
                  May 15, 1997, deliver to Securityholders a brief
                  report, dated as of such May 15, which complies
                  with the provisions of such Section 313(a).

            (b)   A copy of each such report shall, at the time of such
                  transmission to Securityholders, be filed by


                                       32

                  the Trustee with each stock exchange, if any, upon which the
                  Securities are listed, with the Commission and with the
                  Corporation. The Corporation will promptly notify the Trustee
                  when the Securities are listed on any stock exchange.

                  REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                               ON EVENT OF DEFAULT

            SECTION 5.01.     Events of Default.

            One or more of the following events of default shall constitute an
Event of Default hereunder (whatever the reason for such Event of Default and
whether it shall be voluntary 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):

            (a)   default in the payment of any interest upon any Security or
                  any Other Debentures when it becomes due and payable, and
                  continuance of such default for a period of 30 days; provided,
                  however, that a valid extension of an interest payment period
                  by the Corporation in accordance with the terms hereof shall
                  not constitute a default in the payment of interest for this
                  purpose; or

            (b)   default in the payment of all or any part of the principal of
                  (or premium, if any, on) any Security or any Other Debentures
                  as and when the same shall become due and payable either at
                  maturity, upon redemption, by declaration or otherwise; or

            (c)   default in the performance, or breach, of any covenant or
                  warranty of the Corporation in this Indenture (other than a
                  covenant or warranty a default in whose performance or whose
                  breach 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 Corporation by the Trustee or to the
                  Corporation and the Trustee by the holders of at least 25% in
                  aggregate principal amount of the outstanding Securities a
                  written notice specifying such default or breach and
                  requiring it to be remedied and stating that such notice is a
                  "Notice of Default" hereunder; or

            (d)   a court having jurisdiction in the premises shall enter a
                  decree or order for relief in respect of the Corporation in an
                  involuntary case under any applicable bankruptcy, insolvency
                  or other similar law now or hereafter in effect, or appointing
                  a receiver, liquidator, assignee, custodian, trustee,
                  sequestrator (or similar official) of the Corporation or for
                  any substantial part of its property, or ordering the
                  winding-up or liquidation of its affairs and such decree or
                  order shall remain unstayed and in effect for a period of 90
                  consecutive days; or

            (e)   the Corporation shall commence a voluntary case under any
                  applicable bankruptcy, insolvency or other similar law now or
                  hereafter in effect, shall consent to the entry of an order
                  for relief in an involuntary case under any such law, or shall
                  consent to the appointment of or taking possession by a
                  receiver, liquidator, assignee, trustee, custodian,
                  sequestrator (or other similar official) of the Corporation or
                  of any substantial part of its property, or shall make any
                  general assignment for the benefit of creditors, or shall fail
                  generally to pay its debts as they become due.

            If an Event of Default with respect to Securities at the time
outstanding occurs and is continuing, then in every such case the Trustee or the
holders of not less than 25% in aggregate principal amount of the Securities
then outstanding may declare the principal amount of all Securities to be due
and payable immediately, by a notice in writing to the Corporation (and to the
Trustee if given by the holders of the outstanding Securities), and upon any
such declaration the same shall become immediately due and payable.

            The foregoing provisions, however, are subject to the condition that
if, at any time after the principal of the Securities shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, (i)
the Corporation shall pay or shall deposit with the Trustee a sum sufficient to
pay (A) all matured installments of interest upon all the Securities and the
principal of and premium, if any, on any and all Securities which shall have
become due otherwise than by acceleration (with interest upon such principal and
premium, if any, and, to the extent that payment of such interest is enforceable
under applicable law, on overdue installments of interest, at the same rate as
the rate of interest specified in the Securities to the date of such payment or
deposit) and (B) such amount as shall be sufficient to cover reasonable
compensation to the Trustee and each predecessor Trustee, their respective
agents, attorneys and


                                       34
<PAGE>   43
counsel, and all other expenses and liabilities incurred, and all advances made,
by the Trustee and each predecessor Trustee except as a result of negligence or
bad faith, and (ii) any and all Events of Default under the Indenture, other
than the non-payment of the principal of the Securities which shall have become
due solely by such declaration of acceleration, shall have been cured, waived or
otherwise remedied as provided herein, then, in every such case, the holders of
a majority in aggregate principal amount of the Securities then outstanding, by
written notice to the Corporation and to the Trustee, may rescind and annul such
declaration and its consequences, but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

            In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such rescission or annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Corporation, the Trustee and the holders of the Securities shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Corporation, the Trustee and the holders of the
Securities shall continue as though no such proceeding had been taken.

            SECTION 5.02.     Payment of Securities on Default; Suit
                              Therefor.

            The Corporation covenants that (a) in case default shall be made in
the payment of any installment of interest upon any of the Securities as and
when the same shall become due and payable, and such default shall have
continued for a period of 30 days, or (b) in case default shall be made in the
payment of the principal of or premium, if any, on any of the Securities as and
when the same shall have become due and payable, whether at maturity of the
Securities or upon redemption or by declaration or otherwise, then, upon demand
of the Trustee, the Corporation will pay to the Trustee, for the benefit of the
holders of the Securities, the whole amount that then shall have become due and
payable on all such Securities for principal and premium, if any, or interest,
or both, as the case may be, with interest upon the overdue principal and
premium, if any, and (to the extent that payment of such interest is enforceable
under applicable law and, if the Securities are held by Peoples Heritage Capital
Trust or a trustee of such trust, without duplication of any other amounts paid
by Peoples Heritage Capital Trust or a trustee in respect thereof) upon the
overdue installments of interest at the rate borne by the Securities; and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including a reasonable compensation to the Trustee,
its agents, attorneys and counsel, and any expenses or liabilities incurred by
the Trustee hereunder other than through its negligence or bad faith.


                                       35
<PAGE>   44
            In case the Corporation shall fail forthwith to pay such amounts
upon such demand, the Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any actions or proceedings
at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Corporation or any other
obligor on the Securities and collect in the manner provided by law out of the
property of the Corporation or any other obligor on the Securities wherever
situated the moneys adjudged or decreed to be payable.

            In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Corporation or any other obligor on the Securities
under Title 11, United States Code, or any other applicable law, or in case a
receiver or trustee shall have been appointed for the property of the
Corporation or such other obligor, or in the case of any other similar judicial
proceedings relative to the Corporation or other obligor upon the Securities, or
to the creditors or property of the Corporation or such other obligor, the
Trustee, irrespective of whether the principal of the Securities shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 5.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or
claims for the whole amount of principal and interest owing and unpaid in
respect of the Securities and, in case of any judicial proceedings, to file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee (including any claim for reasonable
compensation to the Trustee and each predecessor Trustee, and their respective
agents, attorneys and counsel, and for reimbursement of all expenses and
liabilities incurred, and all advances made, by the Trustee and each predecessor
Trustee, except as a result of negligence or bad faith) and of the
Securityholders allowed in such judicial proceedings relative to the Corporation
or any other obligor on the Securities, or to the creditors or property of the
Corporation or such other obligor, unless prohibited by applicable law and
regulations, to vote on behalf of the holders of the Securities in any election
of a trustee or a standby trustee in arrangement, reorganization, liquidation or
other bankruptcy or insolvency proceedings or person performing similar
functions in comparable proceedings, and to collect and receive any moneys or
other property payable or deliverable on any such claims, and to distribute the
same after the deduction of its charges and expenses; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
Securityholders to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee such amounts as shall be sufficient to
cover reasonable compensation to the Trustee, each


                                       36
<PAGE>   45
predecessor Trustee and their respective agents, attorneys and counsel, and all
other expenses and liabilities incurred, and all advances made, by the Trustee
and each predecessor Trustee except as a result of negligence or bad faith.

            Nothing herein contained shall be construed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Securityholder
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 Securityholder in any such proceeding.

            All rights of action and of asserting claims under this Indenture,
or under any of the Securities, may be enforced by the Trustee without the
possession of any of the Securities, or the production thereof on any trial or
other proceeding relative thereto, and any such suit or proceeding instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment shall be for the ratable benefit of the holders of the
Securities.

            In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Securities, and it shall not be necessary to make any holders of the
Securities parties to any such proceedings.

            SECTION 5.03.     Application of Moneys Collected by Trustee.

            Any moneys collected by the Trustee shall be applied in the order
following, at the date or dates fixed by the Trustee for the distribution of
such moneys, upon presentation of the Securities in respect of which moneys have
been collected, and stamping thereon the payment, if only partially paid, and
upon surrender thereof if fully paid:

            First: To the payment of costs and expenses of collection applicable
to the Securities and reasonable compensation to the Trustee, its agents,
attorneys and counsel, and of all other expenses and liabilities incurred, and
all advances made, by the Trustee except as a result of its negligence or bad
faith;

            Second:  To the payment of all Senior Indebtedness of the
Corporation if and to the extent required by Article XV;

            Third: To the payment of the amounts then due and unpaid upon
Securities for principal of (and premium, if any) and interest on the
Securities, in respect of which or for the benefit of which money has been
collected, ratably, without preference of priority


                                       37
<PAGE>   46
of any kind, according to the amounts due on such Securities for principal (and
premium, if any) and interest, respectively; and

            Fourth:  To the Corporation.

            SECTION 5.04.     Proceedings by Securityholders.

            No holder of any Security shall have any right by virtue of or by
availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof with respect to the
Securities specifying such Event of Default, as hereinbefore provided, and
unless also the holders of not less than 25% in aggregate principal amount of
the Securities then outstanding shall have made written request upon the Trustee
to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred therein
or thereby, and the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity shall have failed to institute any such action,
suit or proceeding, it being understood and intended, and being expressly
covenanted by the taker and holder of every Security with every other taker and
holder and the Trustee, that no one or more holders of Securities shall have any
right in any manner whatever by virtue of or by availing of any provision of
this Indenture to affect, disturb or prejudice the rights of any other holder of
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Securities.

            Notwithstanding any other provisions in this Indenture, however, the
right of any holder of any Security to receive payment of the principal of
(premium, if any) and interest on such Security, on or after the same shall have
become due and payable, or to institute suit for the enforcement of any such
payment, shall not be impaired or affected without the consent of such holder
and by accepting a Security hereunder it is expressly understood, intended and
covenanted by the taker and holder of every Security with every other such taker
and holder and the Trustee, that no one or more holders of Securities shall have
any right in any manner whatsoever by virtue or by availing of any provision of
this Indenture to affect, disturb or prejudice the rights of the holders of any
other Securities, or to obtain or seek to obtain priority over or preference to
any other such holder, or to enforce any right under this Indenture, except in
the manner herein provided and for the equal, ratable and common benefit of all
holders of Securities. For the protection and enforcement of the provisions


                                       38
<PAGE>   47
of this Section , each and every Securityholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

            The Corporation and the Trustee acknowledge that pursuant to the
Declaration, the holders of Capital Securities are entitled, in the
circumstances and subject to the limitations set forth therein, to commence a
Direct Action with respect to any Event of Default under this Indenture and the
Securities.

            SECTION 5.05.     Proceedings by Trustee.

            In case an Event of Default occurs with respect to Securities and is
continuing, the Trustee may in its discretion proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate judicial proceedings
as the Trustee shall deem most effectual to protect and enforce any of such
rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

            SECTION 5.06.     Remedies Cumulative and Continuing.

            Except as provided in the last paragraph of Section 2.08, all powers
and remedies given by this Article V to the Trustee or to the Securityholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of
any other powers and remedies available to the Trustee or the holders of the
Securities, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to the Securities, and no delay or omission
of the Trustee or of any holder of any of the Securities to exercise any right
or power accruing upon any Event of Default occurring and continuing as
aforesaid shall impair any such right or power, or shall be construed to be a
waiver of any such default or an acquiescence therein; and, subject to the
provisions of Section 5.04, every power and remedy given by this Article V or by
law to the Trustee or to the Securityholders may be exercised from time to time,
and as often as shall be deemed expedient, by the Trustee or by the
Securityholders.

            SECTION 5.07.     Direction of Proceedings and Waiver of
                              Defaults by Majority of Securityholders.

            The holders of a majority in aggregate principal amount of the
Securities at the time outstanding 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; provided,
however, that (subject to


                                       39
<PAGE>   48
the provisions of Section 6.01) the Trustee shall have the right to decline to
follow any such direction if the Trustee shall determine that the action so
directed would be unjustly prejudicial to the holders not taking part in such
direction or if the Trustee being advised by counsel determines that the action
or proceeding so directed may not lawfully be taken or if the Trustee in good
faith by its board of directors or trustees, executive committee, or a trust
committee of directors or trustees and/or Responsible Officers shall determine
that the action or proceedings so directed would involve the Trustee in personal
liability. Prior to any declaration accelerating the maturity of the Securities,
the holders of a majority in aggregate principal amount of the Securities at the
time outstanding may on behalf of the holders of all of the Securities waive any
past default or Event of Default and its consequences except a default (a) in
the payment of principal of or premium, if any, or interest on any of the
Securities or (b) in respect of covenants or provisions hereof which cannot be
modified or amended without the consent of the holder of each Security affected;
provided, however, that if the Securities are held by the Property Trustee, such
waiver or modification to such waiver shall not be effective until the holders
of a majority in aggregate liquidation amount of Trust Securities shall have
consented to such waiver or modification to such waiver; provided further, that
if the consent of the holder of each outstanding Security is required, such
waiver shall not be effective until each holder of the Trust Securities shall
have consented to such waiver. Upon any such waiver, the default covered thereby
shall be deemed to be cured for all purposes of this Indenture and the
Corporation, the Trustee and the holders of the Securities shall be restored to
their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other default or impair any right consequent
thereon. Whenever any default or Event of Default hereunder shall have been
waived as permitted by this Section 5.07, said default or Event of Default shall
for all purposes of the Securities and this Indenture be deemed to have been
cured and to be not continuing.

            SECTION 5.08.     Notice of Defaults.

            The Trustee shall, within 90 days after the occurrence of a default
with respect to the Securities mail to all Securityholders, as the names and
addresses of such holders appear upon the Security register, notice of all
defaults known to the Trustee, unless such defaults shall have been cured before
the giving of such notice (the term "defaults" for the purpose of this Section
5.08 being hereby defined to be the events specified in clauses (a), (b), (c),
(d) and (e) of Section 5.01, not including periods of grace, if any, provided
for therein, and irrespective of the giving of written notice specified in
clause (c) of Section 5.01); and provided that, except in the case of default in
the payment of the principal of or premium, if any, or interest on any of the
Securities, the Trustee shall be protected in withholding


                                       40
<PAGE>   49
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 Securityholders; and provided further, that in the case of any default of
the character specified in Section 5.01(c) no such notice to Securityholders
shall be given until at least 60 days after the occurrence thereof but shall be
given within 90 days after such occurrence.

            SECTION 5.09.  Undertaking to Pay 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 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 and
expenses, 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 5.09 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Securityholder, or group of
Securityholders, holding in the aggregate more than 10% in aggregate principal
amount of the Securities outstanding, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Security against the Corporation on or after
the same shall have become due and payable.


                                   ARTICLE VI

                             CONCERNING THE TRUSTEE

            SECTION 6.01.     Duties and Responsibilities of Trustee.

            With respect to the holders of the Securities issued hereunder, the
Trustee, prior to the occurrence of an Event of Default and after the curing or
waiving of all Events of Default which may have occurred, undertakes to perform
such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default has occurred (which has not been cured or
waived) 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 man would exercise or use under the circumstances in the conduct of
his own affairs.

            No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action,


                                       41
<PAGE>   50
its own negligent failure to act or its own willful misconduct, except that

            (a)   prior to the occurrence of an Event of Default and after the
                  curing or waiving of all Events of Default which may have
                  occurred

                  (1)   the duties and obligations of the Trustee shall be
                        determined solely by the express provisions of this
                        Indenture, and the Trustee shall not be liable except
                        for the performance of such duties and obligations 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 the part of the Trustee,
                        the 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 Trustee and conforming to the
                        requirements of this Indenture; but, in the case of any
                        such certificates or opinions which by any provision
                        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)   the Trustee shall not be liable for any error of judgment made
                  in good faith by a Responsible Officer or Officers of the
                  Trustee, unless it shall be proved that the Trustee was
                  negligent in ascertaining the pertinent facts; and

            (c)   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 the Securityholders pursuant
                  to Section 5.07, 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.

            None of the provisions contained in this Indenture shall require the
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 there is reasonable ground for believing that the
repayment of such funds or liability is not reasonably assured to it under the
terms of


                                       42
<PAGE>   51
this Indenture or adequate indemnity against such risk is not reasonably assured
to it.

            SECTION 6.02.     Reliance on Documents, Opinions, etc.

            Except as otherwise provided in Section 6.01:

            (a)   the Trustee may rely and shall be protected in acting or
                  refraining from acting upon any resolution, certificate,
                  statement, instrument, opinion, report, notice, request,
                  consent, order, bond, note, debenture 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)   any request, direction, order or demand of the Corporation
                  mentioned herein may be sufficiently evidenced by an Officers'
                  Certificate (unless other evidence in respect thereof be
                  herein specifically prescribed); and any Board Resolution may
                  be evidenced to the Trustee by a copy thereof certified by
                  the Secretary or an Assistant Secretary of the Corporation;

            (c)   the Trustee may consult with counsel of its selection and any
                  advice or Opinion of Counsel shall be full and complete
                  authorization and protection in respect of any action taken or
                  suffered omitted by it hereunder in good faith and in
                  accordance with such advice or Opinion of Counsel;

            (d)   the Trustee shall be under no obligation to exercise any of
                  the rights or powers vested in it by this Indenture at the
                  request, order or direction of any of the Securityholders,
                  pursuant to the provisions of this Indenture, unless such
                  Securityholders shall have offered to the Trustee reasonable
                  security or indemnity against the costs, expenses and
                  liabilities which may be incurred therein or thereby;

            (e)   the Trustee shall not be liable for any action taken or
                  omitted by it in good faith and believed by it to be
                  authorized or within the discretion or rights or powers
                  conferred upon it by this Indenture; nothing contained
                  herein shall, however, relieve the Trustee of the obligation,
                  upon the occurrence of an Event of Default (that has not been
                  cured or waived), to exercise such of the rights and powers
                  vested in it by this Indenture, and to use the same degree of
                  care and skill in their exercise, as a prudent man would
                  exercise or


                                       43
<PAGE>   52
                  use under the circumstances in the conduct of his own affairs;

            (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, consent, order, approval, bond, debenture, coupon or
                  other paper or document, unless requested in writing to do so
                  by the holders of a majority in aggregate principal amount of
                  the outstanding Securities; provided, however, that if the
                  payment within a reasonable time to the Trustee of the costs,
                  expenses or liabilities likely to be incurred by it in the
                  making of such investigation is, in the opinion of the
                  Trustee, not reasonably assured to the Trustee by the security
                  afforded to it by the terms of this Indenture, the Trustee may
                  require reasonable indemnity against such expense or liability
                  as a condition to so proceeding; 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 (including any Authenticating Agent) or
                  attorneys, and the Trustee shall not be responsible for any
                  misconduct or negligence on the part of any such agent or
                  attorney appointed by it with due care.

            SECTION 6.03.     No Responsibility for Recitals, etc.

            The recitals contained herein and in the Securities (except in the
certificate of authentication of the Trustee or the Authenticating Agent) shall
be taken as the statements of the Corporation and the Trustee and the
Authenticating Agent assume no responsibility for the correctness of the same.
The Trustee and the Authenticating Agent make no representations as to the
validity or sufficiency of this Indenture or of the Securities. The Trustee and
the Authenticating Agent shall not be accountable for the use or application by
the Corporation of any Securities or the proceeds of any Securities
authenticated and delivered by the Trustee or the Authenticating Agent in
conformity with the provisions of this Indenture. The Trustee shall not be
charged with knowledge of any default or Event of Default under Section 5.01(a)
or (b) relating to Other Debentures unless (i) a Responsible Officer of the
Trustee assigned to its Principal Office shall have actual knowledge thereof or
(ii) the Corporation, any Securityholder or the holder of any Other Debenture
shall have given the Trustee written notice thereof in accordance with Section
13.04.


                                       44

            SECTION 6.04. Trustee, Authenticating Agent, Paying Agents, Transfer
                          Agents or Registrar May Own Securities.

            The Trustee or any Authenticating Agent or any paying agent or any
transfer agent or any Security registrar, in its individual or any other
capacity, may become the owner or pledgee of Securities with the same rights it
would have if it were not Trustee, Authenticating Agent, paying agent, transfer
agent or Security registrar.

            SECTION 6.05. Moneys to be Held in Trust.

            Subject to the provisions of Section 11.04, all moneys received by
the Trustee or any paying agent shall, until used or applied as herein provided,
be held in trust for the purpose for which they were received, but need not be
segregated from other funds except to the extent required by law. The Trustee
and any paying agent shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed in writing with the
Corporation. So long as no Event of Default shall have occurred and be
continuing, all interest allowed on any such moneys shall be paid from time to
time upon the written order of the Corporation, signed by the Chairman of the
Board of Directors, the President or a Vice President or the Treasurer or an
Assistant Treasurer of the Corporation.

            SECTION 6.06. Compensation and Expenses of Trustee.

            The Corporation, as borrower, covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, such
compensation as shall be agreed to in writing between the Corporation and the
Trustee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and the Corporation will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith. The Corporation also covenants to
indemnify each of the Trustee or any predecessor Trustee (and its officers,
agents, directors and employees) for, and to hold it harmless against, any and
all loss, damage, claim, liability or expense including taxes (other than taxes
based on the income of the Trustee) incurred without negligence or bad faith on
the part of the Trustee and arising out of or in connection with the acceptance
or administration of this trust, including the costs and expenses of defending
itself against any claim of liability in the premises. The obligations of the
Corporation under this Section 6.06 to compensate and indemnify the Trustee and
to pay or reimburse the


                                       45
<PAGE>   54
Trustee for expenses, disbursements and advances shall constitute additional
indebtedness hereunder. Such additional indebtedness shall be secured by a lien
prior to that of the Securities upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the holders
of particular Securities.

            Without prejudice to any other rights available to the Trustee under
applicable law, when the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(d) or Section
5.01(e), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

            The provisions of this Section shall survive the termination of this
Indenture.

            SECTION 6.07. Officers' Certificate as Evidence.

            Except as otherwise provided in Sections 6.01 and 6.02, whenever in
the administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
omitting any action hereunder, such matter (unless other evidence in respect
thereof is herein specifically prescribed) may, in the absence of negligence or
bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers' Certificate delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken or omitted by
it under the provisions of this Indenture upon the faith thereof.

            SECTION 6.08. Conflicting Interest of Trustee.

            If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and
the Corporation shall in all respects comply with the provisions of Section
310(b) of the Trust Indenture Act, subject to the penultimate paragraph thereof.

            SECTION 6.09. Eligibility of Trustee.

            The Trustee hereunder shall at all times be a corporation organized
and doing business under the laws of the United States of America or any state
or territory thereof or of the District of Columbia or a corporation or other
Person permitted to act as trustee by the Commission authorized under such laws
to exercise corporate trust powers, having a combined capital and surplus of at
least 50 million U.S. dollars ($50,000,000) and subject to supervision or
examination by federal, state, territorial, or


                                       46
<PAGE>   55
District of Columbia 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 6.09 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.

            The Corporation may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Corporation, serve
as Trustee.

            In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.09, the Trustee shall resign
immediately in the manner and with the effect specified in Section 6.10.

            SECTION 6.10. Resignation or Removal of Trustee.

            (a)   The Trustee, or any trustee or trustees hereafter appointed,
                  may at any time resign by giving written notice of such
                  resignation to the Corporation and by mailing notice thereof
                  to the holders of the Securities at their addresses as they
                  shall appear on the Security register. Upon receiving such
                  notice of resignation, the Corporation shall promptly appoint
                  a successor trustee or trustees by written instrument, in
                  duplicate, one copy of which instrument shall be delivered to
                  the resigning Trustee and one copy to the successor trustee.
                  If no successor trustee shall have been so appointed and have
                  accepted appointment within 60 days after the mailing of such
                  notice of resignation to the Securityholders, the resigning
                  Trustee may petition any court of competent jurisdiction for
                  the appointment of a successor trustee, or any
                  Securityholder who has been a bona fide holder of a Security
                  for at least six months may, subject to the provisions of
                  Section 5.09, on behalf of himself and all others similarly
                  situated, petition any such court for the appointment of a
                  successor trustee. Such court may thereupon, after such
                  notice, if any, as it may deem proper and prescribe, appoint
                  a successor trustee.

            (b)   In case at any time any of the following shall occur --

                  (1)   the Trustee shall fail to comply with the provisions of
                        Section 6.08 after written request therefor by the
                        Corporation or by any Securityholder who has been a bona
                        fide holder


                                       47
<PAGE>   56
                        of a Security or Securities for at least six months, or

                  (2)   the Trustee shall cease to be eligible in accordance
                        with the provisions of Section 6.09 and shall fail to
                        resign after written request therefor by the Corporation
                        or by any such Securityholder, 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, the Corporation may remove the Trustee
                  and appoint a successor trustee by written instrument, in
                  duplicate, one copy of which instrument shall be delivered to
                  the Trustee so removed and one copy to the successor trustee,
                  or, subject to the provisions of Section 5.09, any
                  Securityholder 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 and the
                  appointment of a successor trustee. Such court may thereupon,
                  after such notice, if any, as it may deem proper and
                  prescribe, remove the Trustee and appoint a successor trustee.

            (c)   The holders of a majority in aggregate principal
                  amount of the Securities at the time outstanding
                  may at any time remove the Trustee and nominate a
                  successor trustee, which shall be deemed appointed
                  as successor trustee unless within 10 days after
                  such nomination the Corporation objects thereto or
                  if no successor trustee shall have been so
                  appointed and shall have accepted appointment
                  within 30 days after such removal, in which case
                  the Trustee so removed or any Securityholder, upon
                  the terms and conditions and otherwise as in sub-
                  section (a) of this Section 6.10 provided, may
                  petition any court of competent jurisdiction for an
                  appointment of a successor trustee.

            (d)   Any resignation or removal of the Trustee and appointment of a
                  successor trustee pursuant to any of the provisions of this
                  Section 6.10 shall become


                                       48
<PAGE>   57
                        effective upon acceptance of appointment by the
                        successor trustee as provided in Section 6.11.

            SECTION 6.11. Acceptance by Successor Trustee.

            Any successor trustee appointed as provided in Section 6.10 shall
execute, acknowledge and deliver to the Corporation and to its predecessor
trustee an instrument accepting such appointment hereunder, 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, duties and obligations of its predecessor
hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Corporation or of the successor
trustee, the trustee ceasing to act shall, upon payment of any amounts then due
it pursuant to the provisions of Section 6.06, execute and deliver an instrument
transferring to such successor trustee all the rights and powers of the trustee
so ceasing to act and shall duly assign, transfer and deliver to such successor
trustee all property and money held by such retiring trustee thereunder. Upon
request of any such successor trustee, the Corporation shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 6.06.

            No successor trustee shall accept appointment as provided in this
Section 6.11 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 6.08 and eligible under the
provisions of Section 6.09.

            Upon acceptance of appointment by a successor trustee as provided in
this Section 6.11, the Corporation shall mail notice of the succession of such
trustee hereunder to the holders of Securities at their addresses as they shall
appear on the Security register. If the Corporation fails to mail such notice
within 10 days after the acceptance of appointment by the successor trustee, the
successor trustee shall cause such notice to be mailed at the expense of the
Corporation.

            SECTION 6.12. Succession by Merger, etc.

            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 without
the execution or filing of any paper or any further act on the part of any of
the parties hereto.


                                       49
<PAGE>   58
            In case at the time such successor to the Trustee shall succeed to
the trusts created by this Indenture any Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee, and deliver such
Securities so authenticated; and in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor trustee; and in all such cases such certificates shall have the
full force which the Securities or this Indenture elsewhere provides that the
certificate of the Trustee shall have; provided, however, that the right to
adopt the certificate of authentication of any predecessor Trustee or
authenticate Securities in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation.

            SECTION 6.13. Limitation on Rights of Trustee as a Creditor.

            The Trustee shall comply with Section 311(a) of the Trust Indenture
Act, excluding any creditor relationship described in Section 311(b) of the
Trust Indenture Act. A Trustee who has resigned or been removed shall be subject
to Section 311(a) of the Trust Indenture Act to the extent included therein.

            SECTION 6.14. Authenticating Agents.

            There may be one or more Authenticating Agents appointed by the
Trustee upon the request of the Corporation with power to act on its behalf and
subject to its direction in the authentication and delivery of Securities issued
upon exchange or transfer thereof as fully to all intents and purposes as though
any such Authenticating Agent had been expressly authorized to authenticate and
deliver Securities; provided, that the Trustee shall have no liability to the
Corporation for any acts or omissions of the Authenticating Agent with respect
to the authentication and delivery of Securities. Any such Authenticating Agent
shall at all times be a corporation organized and doing business under the laws
of the United States or of any state or territory thereof or of the District of
Columbia authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of at least $5,000,000 and being subject to
supervision or examination by federal, state, territorial or District of
Columbia authority. If such corporation publishes reports of condition at least
annually pursuant to law or the requirements of such authority, then for the
purposes of this Section 6.14 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 an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section , it


                                       50
<PAGE>   59
shall resign immediately in the manner and with the effect herein specified in
this Section .

            Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of any Authenticating Agent, shall be the successor
of such Authenticating Agent hereunder, if such successor corporation is
otherwise eligible under this Section 6.14 without the execution or filing of
any paper or any further act on the part of the parties hereto or such
Authenticating Agent.

            Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Corporation. The Trustee may at
any time terminate the agency of any Authenticating Agent by giving written
notice of termination to such Authenticating Agent and to the Corporation. Upon
receiving such a notice of resignation or upon such a termination, or in case at
any time any Authenticating Agent shall cease to be eligible under this Section
6.14, the Trustee may, and upon the request of the Corporation shall, promptly
appoint a successor Authenticating Agent eligible under this Section 6.14, shall
give written notice of such appointment to the Corporation and shall mail notice
of such appointment to all Securityholders as the names and addresses of such
holders appear on the Security Register. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all rights,
powers, duties and responsibilities of its predecessor hereunder, with like
effect as if originally named as Authenticating Agent herein.

            The Corporation, as borrower, agrees to pay to any Authenticating
Agent from time to time reasonable compensation for its services. Any
Authenticating Agent shall have no responsibility or liability for any action
taken by it as such in accordance with the directions of the Trustee.


                                   ARTICLE VII

                         CONCERNING THE SECURITYHOLDERS

            SECTION 7.01.     Action by Securityholders.

            Whenever in this Indenture it is provided that the holders of a
specified percentage in aggregate principal amount of the Securities may take
any action (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action) the fact that at
the time of taking any such action the holders of such specified percentage have
joined therein may be evidenced (a) by any instrument or any number


                                       51
<PAGE>   60
of instruments of similar tenor executed by such Securityholders in person or by
agent or proxy appointed in writing, or (b) by the record of such holders of
Securities voting in favor thereof at any meeting of such Securityholders duly
called and held in accordance with the provisions of Article VIII, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of such Securityholders.

            If the Corporation shall solicit from the Securityholders any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Corporation may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for the determination of
Securityholders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other action or to revoke any such action, but the
Corporation shall have no obligation to do so. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
action or revocation may be given before or after the record date, but only the
Securityholders of record at the close of business on the record date shall be
deemed to be Securityholders for the purposes of determining whether
Securityholders of the requisite proportion of Outstanding Securities have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other action, and for that purpose the
Outstanding Securities shall be computed as of the record date; provided,
however, that no such authorization, agreement or consent by such
Securityholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

            SECTION 7.02.     Proof of Execution by Securityholders.

            Subject to the provisions of Section 6.01, 6.02 and 8.05, proof of
the execution of any instrument by a Securityholder or his agent or proxy shall
be sufficient if made in accordance with such reasonable rules and regulations
as may be prescribed by the Trustee or in such manner as shall be satisfactory
to the Trustee. The ownership of Securities shall be proved by the Security
Register or by a certificate of the Security registrar. The Trustee may require
such additional proof of any matter referred to in this Section as it shall deem
necessary.

            The record of any Securityholders' meeting shall be proved in the
manner provided in Section 8.06.

            SECTION 7.03.     Who Are Deemed Absolute Owners.

            Prior to due presentment for registration of transfer of any
Security, the Corporation, the Trustee, any Authenticating Agent, any paying
agent, any transfer agent and any Security registrar may deem the person in
whose name such Security shall be


                                       52
<PAGE>   61
registered upon the Security Register to be, and may treat him as, the absolute
owner of such Security (whether or not such Security shall be overdue) for the
purpose of receiving payment of or on account of the principal of and premium,
if any, and (subject to Section 2.06) interest on such Security and for all
other purposes; and neither the Corporation nor the Trustee nor any
Authenticating Agent nor any paying agent nor any transfer agent nor any
Security registrar shall be affected by any notice to the contrary. All such
payments so made to any holder for the time being or upon his order shall be
valid, and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for moneys payable upon any such Security.

            SECTION 7.04. Securities Owned by Corporation Deemed Not
                          Outstanding.

            In determining whether the holders of the requisite aggregate
principal amount of Securities have concurred in any direction, consent or
waiver under this Indenture, Securities which are owned by the Corporation or
any other obligor on the Securities or by any person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Corporation or any other obligor on the Securities shall be disregarded and
deemed not to be outstanding for the purpose of any such determination; provided
that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, consent or waiver, only Securities which the
Trustee actually knows are so owned shall be so disregarded. Securities so owned
which have been pledged in good faith may be regarded as outstanding for the
purposes of this Section 7.04 if the pledgee shall establish to the satisfaction
of the Trustee the pledgee's right to vote such Securities and that the pledgee
is not the Corporation or any such other obligor or person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Corporation or any such other obligor. In the case of a dispute
as to such right, any decision by the Trustee taken upon the advice of counsel
shall be full protection to the Trustee.

            SECTION 7.05. Revocation of Consents; Future Holders Bound.

            At any time prior to (but not after) the evidencing to the Trustee,
as provided in Section 7.01, of the taking of any action by the holders of the
percentage in aggregate principal amount of the Securities specified in this
Indenture in connection with such action, any holder of a Security (or any
Security issued in whole or in part in exchange or substitution therefor),
subject to Section 7.01, the serial number of which is shown by the evidence to
be included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee at its principal office and upon
proof of holding as provided in Section 7.02, revoke such action so far as
concerns


                                       53
<PAGE>   62
such Security (or so far as concerns the principal amount represented by any
exchanged or substituted Security). Except as aforesaid any such action taken by
the holder of any Security shall be conclusive and binding upon such holder and
upon all future holders and owners of such Security, and of any Security issued
in exchange or substitution therefor, irrespective of whether or not any
notation in regard thereto is made upon such Security or any Security issued in
exchange or substitution therefor.

                                  ARTICLE VIII

                            SECURITYHOLDERS' MEETINGS

            SECTION 8.01. Purposes of Meetings.

            A meeting of Securityholders may be called at any time and from time
to time pursuant to the provisions of this Article VIII for any of the following
purposes:

            (a)   to give any notice to the Corporation or to the Trustee, or to
                  give any directions to the Trustee, or to consent to the
                  waiving of any default hereunder and its consequences, or to
                  take any other action authorized to be taken by
                  Securityholders pursuant to any of the provisions of Article
                  V;

            (b)   to remove the Trustee and nominate a successor trustee
                  pursuant to the provisions of Article VI;

            (c)   to consent to the execution of an indenture or indentures
                  supplemental hereto pursuant to the provisions of Section
                  9.02; or

            (d)   to take any other action authorized to be taken by or on
                  behalf of the holders of any specified aggregate principal
                  amount of such Securities under any other provision of this
                  Indenture or under applicable law.

            SECTION 8.02. Call of Meetings by Trustee.

            The Trustee may at any time call a meeting of Securityholders to
take any action specified in Section 8.01, to be held at such time and at such
place in the Borough of Manhattan, The City of New York, as the Trustee shall
determine. Notice of every meeting of the Securityholders, setting forth the
time and the place of such meeting and in general terms the action proposed to
be taken at such meeting, shall be mailed to holders of Securities at their
addresses as they shall appear on the Securities Register. Such notice shall be
mailed not less than 20 nor more than 180 days prior to the date fixed for the
meeting.


                                       54
<PAGE>   63
            SECTION 8.03. Call of Meetings by Corporation or Securityholders.

            In case at any time the Corporation pursuant to a resolution of the
Board of Directors, or the holders of at least 10% in aggregate principal amount
of the Securities then outstanding, shall have requested the Trustee to call a
meeting of Securityholders, by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not
have mailed the notice of such meeting within 20 days after receipt of such
request, then the Corporation or such Securityholders may determine the time and
the place in said Borough of Manhattan for such meeting and may call such
meeting to take any action authorized in Section 8.01, by mailing notice thereof
as provided in Section 8.02.

            SECTION 8.04. Qualifications for Voting.

            To be entitled to vote at any meeting of Securityholders a person
shall (a) be a holder of one or more Securities or (b) a person appointed by an
instrument in writing as proxy by a holder of one or more Securities. The only
persons who shall be entitled at any meeting of Securityholders shall be the
persons entitled to vote at such meeting and their counsel and any
representatives of the Trustee and its counsel and any representatives of the
Corporation and its counsel.

            SECTION 8.05. Regulations.

            Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Securityholders, in regard to proof of the holding of Securities and of the
appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

            The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Corporation or by Securityholders as provided in Section 8.03, in which case the
Corporation or the Securityholders calling the meeting, as the case may be,
shall in like manner appoint a temporary chairman. A permanent chairman and a
permanent secretary of the meeting shall be elected by majority vote of the
meeting.

            Subject to the provisions of Section 8.04, at any meeting each
holder of Securities or proxy therefor shall be entitled to one vote for each
$1,000 principal amount of Securities held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as


                                       55
<PAGE>   64
not outstanding and ruled by the chairman of the meeting to be not outstanding.
The chairman of the meeting shall have no right to vote other than by virtue of
Securities held by him or instruments in writing as aforesaid duly designating
him as the person to vote on behalf of other Securityholders. Any meeting of
Securityholders duly called pursuant to the provisions of Section 8.02 or 8.03
may be adjourned from time to time by a majority of those present, whether or
not constituting a quorum, and the meeting may be held as so adjourned without
further notice.

            The Persons entitled to vote a majority in principal amount of the
outstanding Securities shall constitute a quorum for a meeting of Holders of
Securities; provided, however, that if any action is to be taken at such meeting
with respect to a consent, waiver, request, demand, notice, authorization,
direction or other action which may be given by the holders of not less than a
specified percentage in principal amount of the outstanding Securities, the
Persons holding or representing such specified percentage in principal amount of
the outstanding Securities will constitute a quorum. In the absence of a quorum
within 30 minutes of the time appointed for any such meeting, the meeting shall,
if convened at the request of holders of Securities, be dissolved. In any other
case the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10 days
as determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any adjourned meeting shall be
given as provided in Section 8.02, except that such notice need be given only
once not less than five days prior to the date on which the meeting is scheduled
to be reconvened. Notice of the reconvening of an adjourned meeting shall state
expressly the percentage, as provided above, of the principal amount of the
outstanding Securities which shall constitute a quorum.

            Except as limited by the first proviso to the first paragraph of
Section 9.02, any resolution presented to a meeting or adjourned meeting duly
reconvened at which a quorum is present as aforesaid may be adopted by the
affirmative vote of the holders of a majority in principal amount of the
outstanding Securities; provided, however, that, except as limited by the first
proviso to the first paragraph of Section 9.02, any resolution with respect to
any consent, waiver, request, demand, notice, authorization, direction or other
action which this Indenture expressly provides may be given by the holders of
not less than a specified percentage in principal amount of the outstanding
Securities may be adopted at a meeting or an adjourned meeting duly reconvened
and at which a quorum is present as aforesaid only by the affirmative vote of
the holders of not less than such specified percentage in principal amount of
the outstanding Securities.

<PAGE>   65
            Any resolution passed or decision taken at any meeting of Holders of
Securities duly held in accordance with this Section shall be binding on all the
Holders of Securities whether or not present or represented at the meeting.

            SECTION 8.06. Voting.

            The vote upon any resolution submitted to any meeting of holders of
Securities shall be by written ballots on which shall be subscribed the
signatures of such holders or of their representatives by proxy and the serial
number or numbers of the Securities held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
triplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Securityholders shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the facts setting forth a
copy of the notice of the meeting and showing that said notice was mailed as
provided in Section 8.02. The record shall show the serial numbers of the
Securities voting in favor of or against any resolution. The record shall be
signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one of the duplicates shall be delivered to the Corporation and
the other to the Trustee to be preserved by the Trustee, the latter to have
attached thereto the ballots voted at the meeting. The holders of the Series A
Capital Securities and the Series B Capital Securities shall vote for all
purposes as a single class.

time outstanding, the Corporation, when authorized by a Board Resolution, and
the Trustee may from time to time and at any time amend the Indenture for the
purpose of adding any provisions to or changing in any manner or eliminating any

by Article XVI), or reduce the principal amount thereof, or reduce any amount
payable on redemption thereof, or make the principal thereof or any interest or
premium thereon payable in any coin or currency other than that provided in the
Securities, or impair or affect the right of any Securityholder to institute
suit for payment thereof, or (ii) reduce the aforesaid percentage of Securities
the holders of which are required to consent to any such amendment to the
Indenture, provided, however, that if the Securities are held by


                                       59
<PAGE>   68

holders of a majority in liquidation amount of Trust Securities shall have
consented to such amendment; provided, further, that if the consent of the
holder of each outstanding Security is required, such amendment shall not be
effective until each holder of the Trust Securities shall have consented to such
amendment.

            Upon the request of the Corporation accompanied by a copy of a
resolution of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture affecting such
amendment, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid, the Trustee shall join with the Corporation in the

otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall transmit by mail, first class postage prepaid, a notice, prepared
by the Corporation, setting forth in general terms the substance of such
supplemental indenture, to the Securityholders as their names and addresses
appear upon the Security Register. Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

            It shall not be necessary for the consent of the Securityholders
under this Section 9.02 to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such consent shall approve
the substance thereof.

            SECTION 9.03.     Compliance with Trust Indenture Act;
                              Effect of Supplemental Indentures.

this Article IX shall comply with the Trust Indenture Act. Upon the execution of
any supplemental indenture pursuant to the provisions of this Article IX, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Indenture of the Trustee, the Corporation and the
holders of Securities shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments and all
the terms and conditions of any such supplemental indenture shall be and be
deemed to be part of the terms and conditions of this Indenture for any and all

provided for in such supplemental indenture. If the Corporation or the Trustee
shall so determine, new Securities so modified as to conform, in the opinion of
the Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared and executed by the
Corporation, authenticated by the Trustee or the Authenticating Agent and

                  of any payment, money in an amount, or (iii) a combination of
                  (i) and (ii), sufficient, in the opinion (with respect to (ii)
                  and (iii)) of a nationally recognized firm of independent

                  or loss for United States federal income tax purposes as a
                  result of the exercise of the option under this Section 11.05
                  and will be subject to United States federal income tax on the
                  same amount and in the same manner and at the same times as
                  would have been the case if such option had not been
                  exercised, and such opinion shall be based on a statute so
                  providing or be accompanied by a private letter ruling to that
                  effect received from the United States Internal Revenue
                  Service or a revenue ruling pertaining to a comparable form of
                  transaction to that effect published by the United States
                  Internal Revenue Service.

            SECTION 13.09. Table of Contents, Headings, etc.

            The table of contents and the titles and headings of the articles

            SECTION 13.10. Execution in Counterparts.

            This Indenture may be executed in any number of counterparts, each
of which shall be an original, but such counterparts shall together constitute

            SECTION 13.11. Separability.

            In case any one or more of the provisions contained in this

            SECTION 13.12. Assignment.

            The Corporation will have the right at all times to assign any of

Trust any holder of Capital Securities may institute legal proceedings directly
against

                                       70
<PAGE>   79
the Corporation to enforce such Property Trustee's rights under this Indenture
without first instituting any legal proceedings against such Property Trustee or
any other person or entity. Notwithstanding the foregoing, if an Event of
Default has occurred and is continuing and such event is attributable to the
failure of the Corporation to pay principal of or premium, if any, or interest
on the Securities when due, the Corporation acknowledges that a holder of
Capital Securities may directly institute a proceeding for enforcement of
payment to such holder of the principal of or premium, if any, or interest on
the Securities having a principal amount equal to the aggregate liquidation
amount of the Capital Securities of such holder on or after the respective due
date specified in the Securities.

            If a Special Event has occurred and is continuing then,

which notice shall be accompanied by an Officers' Certificate certifying that a
Special Event entitling the Corporation to redeem the Securities pursuant to
this Section, has occurred and (ii) not less than 30 days nor more than 60 days
written notice to the Securityholders, to redeem the Securities, in whole (but
not in part), within 90 days following the occurrence of such Special Event at
the Special Event Redemption Price. Following a Special Event, the Corporation
shall take such action as is necessary to promptly determine the Special Event
Redemption Price, including without limitation the appointment by the
Corporation of a Quotation Agent. The Special Event Redemption Price shall be
paid prior to 12:00 noon, New York time, on the date of such redemption or such
earlier time as the Corporation determines, provided that the Corporation shall
deposit with the Trustee an amount sufficient to pay the Special Event
Redemption Price by 10:00 a.m., New York time, on the date such Special Event
Prepayment Price is to be paid. The Corporation shall provide the Trustee with
written notice of the Special Event Redemption Price promptly after the
calculation thereof, which notice shall include any calculation made by the
Quotation Agent in connection with the determination of the Special Event
Redemption Price.

            SECTION 14.02. Optional Redemption by Corporation.

            If the Securities are only partially redeemed pursuant to this
Section 14.02, the Securities will be redeemed by lot or by any other method
utilized by the Trustee; provided, that if at the time of redemption the
Securities are registered as a Global Security, the Depositary shall determine,
in accordance with its procedures, the principal amount of such Securities held
for the account of its participants to be redeemed. The Optional Redemption
Price shall be paid prior to 12:00 noon, New York time, on the date of such
redemption or at such earlier time as the Corporation determines, provided that
the Corporation shall deposit with the Trustee an amount sufficient to pay the
Optional Redemption Price by 10:00 a.m., New York time, on the date such
Optional Redemption Price is to be paid.

            (b) Notwithstanding the first sentence of Section 14.02, upon the
entry of an order for dissolution of the Peoples Heritage Capital Trust by a
court of competent jurisdiction, the Securities thereafter will be subject to
optional redemption, in whole only, but not in part, on or after February 1,
2007, at the optional redemption prices set forth in Section 14.02 and otherwise
in accordance with this Article XIV.

            (c) Any redemption of Securities pursuant to Section 14.01 or
Section 14.02 shall be subject to the receipt by the Corporation of any required
regulatory approval.

            SECTION 14.03. No Sinking Fund.

            The Securities are not entitled to the benefit of any sinking fund.

            SECTION 14.04. Notice of Redemption; Selection of Securities.

            In case the Corporation shall desire to exercise the right to redeem
all, or, as the case may be, any part of the Securities in accordance with their
terms, it shall fix a date for redemption and shall mail a notice of such
redemption at least 30 and not more than 60 days prior to the date fixed for
redemption to the holders of Securities so to be redeemed as a whole or in part
at their last addresses as the same appear on the Security Register. Such
mailing shall be by first class mail. 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 any case, 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.

            Each such notice of redemption shall specify the CUSIP number of the
Securities to be redeemed, the date fixed for redemption, the redemption price
at which the Securities are to be redeemed (or the method by which such
redemption price is to be calculated), the place or places of payment, that
payment will be made upon presentation and surrender of the Securities, that
interest accrued to the date fixed for redemption will be paid as specified in
said notice, and that on and after said date interest thereon or on the portions
thereof to be redeemed will cease to accrue. If less than all the Securities are
to be redeemed the notice of redemption shall specify the numbers of the
Securities to be redeemed. In case any Security is to be redeemed in part only,
the notice of redemption shall state the portion of the principal amount thereof
to be redeemed and shall state that on and after the date fixed for redemption,
upon surrender of such Security, a new Security or Securities in principal
amount equal to the unredeemed portion thereof will be issued.

            By 10:00 a.m. New York time on the redemption date specified in the
notice of redemption given as provided in this Section, the Corporation will
deposit with the Trustee or with one or more paying agents an amount of money
sufficient to redeem on the redemption date all the Securities so called for
redemption at the appropriate Redemption Price, together with accrued interest
to the date fixed for redemption.

            The Corporation will give the Trustee notice not less than 45 days
prior to the redemption date as to the aggregate


                                       73
<PAGE>   82
principal amount of Securities to be redeemed and the Trustee shall select, in
such manner as in its sole discretion it shall deem appropriate and fair, the
Securities or portions thereof (in integral multiples of $1,000, except as
otherwise set forth in the applicable form of Security) to be redeemed.

            SECTION 14.05. Payment of Securities Called for Redemption.

            If notice of redemption has been given as provided in Section 14.04,
the Securities or portions 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, together with interest
accrued to the date fixed for redemption (subject to the rights of holders of
Securities on the close of business on a regular record date in respect of an
Interest Payment Date occurring on or prior to the redemption date), and on and
after said date (unless the Corporation shall default in the payment of such
Securities at the Redemption Price, together with interest accrued to said date)
interest on the Securities or portions of Securities so called for redemption
shall cease to accrue. On presentation and surrender of such Securities at a
place of payment specified in said notice, the said Securities or the specified
portions thereof shall be paid and redeemed by the Corporation at the applicable
Redemption Price, together with interest accrued thereon to the date fixed for
redemption (subject to the rights of holders of Securities on the close of
business on a regular record date in respect of an Interest Payment Date
occurring on or prior to the redemption date).

            Upon presentation of any Security redeemed in part only, the
Corporation shall execute and the Trustee shall authenticate and make available
for delivery to the holder thereof, at the expense of the Corporation, a new
Security or Securities of authorized denominations, in principal amount equal to
the unredeemed portion of the Security so presented.


                                   ARTICLE XV

                           SUBORDINATION OF SECURITIES

            SECTION 15.01. Agreement to Subordinate.

            The Corporation covenants and agrees, and each holder of Securities
issued hereunder likewise covenants and agrees, that the Securities shall be
issued subject to the provisions of this Article XV; and each holder of a
Security, whether upon original issue or upon transfer or assignment thereof,
accepts and agrees to be bound by such provisions.


                                       74
<PAGE>   83
            The payment by the Corporation of the principal of, premium, if any,
and interest on all Securities issued hereunder shall, to the extent and in the
manner hereinafter set forth, be subordinated and junior in right of payment to
the prior payment in full of Senior Indebtedness, whether outstanding at the
date of this Indenture or thereafter incurred.

            No provision of this Article XV shall prevent the occurrence of any
Default or Event of Default hereunder.

            SECTION 15.02. Default on Senior Indebtedness.

            In the event and during the continuation of any default by the
Corporation in the payment of principal, premium, interest or any other payment
due on any Senior Indebtedness, or in the event that the maturity of any Senior
Indebtedness has been accelerated because of a default, then, in either case, no
payment shall be made by the Corporation with respect to the principal
(including redemption payments) of or premium, if any, or interest on the
Securities.

            In the event of the acceleration of the maturity of the Securities,
then no payment shall be made by the Corporation with respect to the principal
(including redemption payments) of or premium, if any, or interest on the
Securities until the holders of all Senior Indebtedness outstanding at the time
of such acceleration shall receive payment in full of such Senior Indebtedness
(including any amounts due upon acceleration).

            In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee when such payment is prohibited by the preceding
paragraphs of this Section 15.02, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing, within 90 days of
such payment on such Senior Indebtedness.

            SECTION 15.03. Liquidation; Dissolution; Bankruptcy.

            Upon any payment by the Corporation or distribution of assets of the
Corporation of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution or winding-up or liquidation or reorganization
of the Corporation, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all Senior Indebtedness of the
Corporation shall first be paid in full, or payment thereof provided for in
money in accordance with its terms, before any


                                       75
<PAGE>   84
payment is made by the Corporation on account of the principal (and premium, if
any) or interest on the Securities; and upon any such dissolution or winding-up
or liquidation or reorganization, any payment by the Corporation, or
distribution of assets of the Corporation of any kind or character, whether in
cash, property or securities, to which the Securityholders or the Trustee would
be entitled to receive from the Corporation, except for the provisions of this
Article XV, shall be paid by the Corporation or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Securityholders or by the Trustee under the Indenture if
received by them or it, directly to the holders of Senior Indebtedness of the
Corporation or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay Senior Indebtedness in full, in money or
money's worth, after giving effect to any concurrent payment or distribution to
or for the holders of such Senior Indebtedness, before any payment or
distribution is made to the Securityholders or to the Trustee.

            In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Corporation of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received by
the Trustee before all Senior Indebtedness is paid in full, or provision is made
for such payment in money in accordance with its terms, such payment or
distribution shall be held in trust for the benefit of and shall be paid over or
delivered to the holders of such Senior Indebtedness or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Indebtedness may have been issued,
as their respective interests may appear, as calculated by the Corporation, for
application to the payment of all Senior Indebtedness remaining unpaid to the
extent necessary to pay Senior Indebtedness in full in money in accordance with
its terms, after giving effect to any concurrent payment or distribution to or
for the benefit of the holders of such Senior Indebtedness.

            For purposes of this Article XV, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Corporation as
reorganized or readjusted, or securities of the Corporation or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this Article
XV with respect to the Securities to the payment of Senior Indebtedness that may
at the time be outstanding, provided that (i) such Senior Indebtedness is
assumed by the new corporation, if any, resulting from any such reorganization
or readjustment, and (ii) the rights of the holders of such Senior Indebtedness
are not, without the consent of such holders, altered by such reorganization or 


                                       76
<PAGE>   85
readjustment. The consolidation of the Corporation with, or the merger of the
Corporation into, another Person or the liquidation or dissolution of the
Corporation following the sale, conveyance, transfer or lease of its property as
an entirety, or substantially as an entirety, to another Person upon the terms
and conditions provided for in Article X of this Indenture shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 15.03 if such other Person shall, as a part of such consolidation,
merger, sale, conveyance, transfer or lease, comply with the conditions stated
in Article X of this Indenture.

            SECTION 15.04. Subrogation.

            Subject to the payment in full of Senior Indebtedness, the rights of
the Securityholders shall be subrogated to the rights of the holders of such
Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Corporation, as the case may be, applicable to such Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full; and, for the purposes of such subrogation, no
payments or distributions to the holders of such Senior Indebtedness of any
cash, property or securities to which the Securityholders or the Trustee would
be entitled except for the provisions of this Article XV, and no payment over
pursuant to the provisions of this Article XV to or for the benefit of the
holders of such Senior Indebtedness by Securityholders or the Trustee, shall, as
between the Corporation, its creditors other than holders of Senior Indebtedness
of the Corporation, and the holders of the Securities, be deemed to be a payment
by the Corporation to or on account of such Senior Indebtedness. It is
understood that the provisions of this Article XV are and are intended solely
for the purposes of defining the relative rights of the holders of the
Securities, on the one hand, and the holders of such Senior Indebtedness on the
other hand.

            Nothing contained in this Article XV or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as between the Corporation,
its creditors other than the holders of Senior Indebtedness of the Corporation,
and the holders of the Securities, the obligation of the Corporation, which is
absolute and unconditional, to pay to the holders of the Securities the
principal of (and premium, if any) and interest on the Securities as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the holders of the Securities
and creditors of the Corporation, as the case may be, other than the holders of
Senior Indebtedness of the Corporation, as the case may be, nor shall anything
herein or therein prevent the Trustee or the holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
the Indenture, subject to the rights, if any, under this Article XV of the
holders of such Senior Indebt-


                                       77

edness in respect of cash, property or securities of the Corporation, as the
case may be, received upon the exercise of any such remedy.

            SECTION 15.05. Trustee to Effectuate Subordination.

            Each Securityholder by such Securityholder's acceptance thereof
authorizes and directs the Trustee on such Securityholder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article XV and appoints the Trustee such Securityholder's
attorney-in-fact for any and all such purposes.

            SECTION 15.06. Notice by the Corporation.

            The Corporation shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Corporation that would prohibit
the making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article XV. Notwithstanding the
provisions of this Article XV or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment of monies to or by the Trustee in
respect of the Securities pursuant to the provisions of this Article XV, unless
and until a Responsible Officer of the Trustee assigned to its Principal Office
shall have received written notice thereof from the Corporation or a holder or
holders of Senior Indebtedness or from any trustee therefor; and before the
receipt of any such written notice, the Trustee, subject to the provisions of
Article VI of this Indenture, shall be entitled in all respects to assume that
no such facts exist; provided, however, that if the Trustee shall not have
received the notice provided for in this Section 15.06 at least two Business
Days prior to the date (i) upon which by the terms hereof any money may become
payable for any purpose (including, without limitation, the payment of the
principal of (or premium, if any) or interest on any Security), or (ii) moneys
and/or U.S. Government Obligations are deposited in trust pursuant to Article XI
then, anything herein contained to the contrary notwithstanding, the Trustee
shall have full power and authority to receive such money and U.S. Government
Obligations and to apply the same to the purposes for which they were received,
and shall not be affected by any notice to the contrary that may be received by
it within two Business Days prior to such date.

            The Trustee, subject to the provisions of Article VI of this
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Corporation (or a trustee or representative on behalf of
such holder) to establish that such notice has been given by a holder of such
Senior Indebtedness or a trustee or representative on behalf of any such holder
or holders. In the event that the Trustee determines in good faith


                                       78
<PAGE>   87
that further evidence is required with respect to the right of any Person as a
holder of such Senior Indebtedness to participate in any payment or distribution
pursuant to this Article XV, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of such
Senior Indebtedness 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 XV, 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.

            Upon any payment or distribution of assets of the Corporation
referred to in this Article XV, the Trustee and the Securityholders shall be
entitled to rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other
person making such payment or distribution, delivered to the Trustee or to the
Securityholders, for the purpose of ascertaining the persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
and other indebtedness of the Corporation, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article XV.

            SECTION 15.07. Rights of the Trustee; Holders of Senior
                           Indebtedness.

            The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XV in respect of any Senior Indebtedness at any
time held by it, to the same extent as any other holder of Senior Indebtedness,
and nothing in this Indenture shall deprive the Trustee of any of its rights as
such holder.

            With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article XV, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and, subject to the
provisions of Article VI of this Indenture, the Trustee shall not be liable to
any holder of Senior Indebtedness if it shall pay over or deliver to
Securityholders, the Corporation or any other Person money or assets to which
any holder of Senior Indebtedness shall be entitled by virtue of this Article XV
or otherwise.


                                       79
<PAGE>   88
            Nothing in this Article XV shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 6.06.

            SECTION 15.08. Subordination May Not Be Impaired.

            No right of any present or future holder of any Senior Indebtedness
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
Corporation or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Corporation with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof that any such
holder may have or otherwise be charged with.

            Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Securityholders,
without incurring responsibility to the Securityholders and without impairing or
releasing the subordination provided in this Article XV or the obligations
hereunder of the holders of the Securities to the holders of Senior
Indebtedness, 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, such
Senior Indebtedness, or otherwise amend or supplement in any manner such Senior
Indebtedness or any instrument evidencing the same or any agreement under which
such Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of such Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Corporation and any other Person.


                                   ARTICLE XVI

                      EXTENSION OF INTEREST PAYMENT PERIOD

            SECTION 16.01. Extension of Interest Payment Period.

            So long as no Event of Default has occurred and is continuing, the
Corporation shall have the right, at any time and from time to time during the
term of the Securities, to defer payments of interest by extending the interest
payment period of such Securities for a period not exceeding 10 consecutive
semi-annual periods, including the first such semi-annual period during such
extension period (the "Extended Interest Payment Period"), during which Extended
Interest Payment Period no interest shall be due and payable; provided that no
Extended Interest Payment Period shall end on a date other than an Interest
Payment Date or extend beyond the Maturity Date. To the extent permitted by
applicable law, interest, the payment of which has been deferred because of the


                                       80
<PAGE>   89
extension of the interest payment period pursuant to this Section 16.01, will
bear interest thereon at the Coupon Rate compounded semi-annually for each
semi-annual period of the Extended Interest Payment Period ("Compounded
Interest"). At the end of the Extended Interest Payment Period, the Corporation
shall pay all interest accrued and unpaid on the Securities, including any
Additional Interest and Compounded Interest (together, "Deferred Interest") that
shall be payable to the holders of the Securities in whose names the Securities
are registered in the Security Register on the first record date preceding the
end of the Extended Interest Payment Period. Before the termination of any
Extended Interest Payment Period, the Corporation may further defer payments of
interest by further extending such period, provided that such period, together
with all such previous and further extensions within such Extended Interest
Payment Period, shall not exceed 10 consecutive semi-annual periods, including
the first such semi-annual period during such Extended Interest Payment Period,
or extend beyond the Maturity Date. Upon the termination of any Extended
Interest Payment Period and the payment of all Deferred Interest then due, the
Corporation may commence a new Extended Interest Payment Period, subject to the
foregoing requirements. No interest shall be due and payable during an Extended
Interest Payment Period, except at the end thereof, but the Corporation may
prepay at any time all or any portion of the interest accrued during an Extended
Interest Payment Period.

            SECTION 16.02. Notice of Extension.

            (a) If the Property Trustee is the only registered holder of the
Securities at the time the Corporation selects an Extended Interest Payment
Period, the Corporation shall give written notice to the Administrative
Trustees, the Property Trustee and the Trustee of its selection of such Extended
Interest Payment Period five Business Days before the earlier of (i) the next
succeeding date on which Distributions on the Trust Securities issued by Peoples
Heritage Capital Trust are payable, or (ii) the date Peoples Heritage Capital
Trust is required to give notice of the record date, or the date such
Distributions are payable, to any national securities exchange or to holders of
the Capital Securities issued by Peoples Heritage Capital Trust, but in any
event at least five Business Days before such record date.

            (b) If the Property Trustee is not the only holder of the Securities
at the time the Corporation selects an Extended Interest Payment Period, the
Corporation shall give the holders of the Securities and the Trustee written
notice of its selection of such Extended Interest Payment Period at least 10
Business Days before the earlier of (i) the next succeeding Interest Payment
Date, or (ii) the date the Corporation is required to give notice of the record
or payment date of such interest payment to any national securities exchange.

            (c) The semi-annual period in which any notice is given pursuant to
paragraphs (a) or (b) of this Section 16.02 shall be counted as one of the 10
semi-annual periods permitted in the maximum Extended Interest Payment Period
permitted under Section 16.01.

       9.06% SERIES __ JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE
                              DUE FEBRUARY 1, 2027

            Peoples Heritage Financial Group, Inc., a Maine corporation (the
"Corporation", which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to The Bank
of New York, as Property Trustee for Peoples Heritage Capital Trust I or
registered assigns, the principal sum of One Hundred Three Million Ninety-Three
Thousand Dollars ($103,093,000) on February 1, 2027 (the "Maturity Date"),
unless previously redeemed, and to pay interest on the outstanding principal
amount hereof from January 31, 1997, or from the most recent interest payment
date (each such date, an "Interest Payment Date") to which interest has been
paid or duly provided for, semi-annually (subject to deferral as set forth
herein) in arrears on February 1 and August 1 of each year, commencing August 1,
1997 at the rate of 9.06% per annum until the principal hereof shall have become
due and payable, and at the same rate per annum on any overdue principal and
premium, if any, and (without duplication and to the extent that payment of such
interest is enforceable under applicable law) on any overdue installment of
interest at the same rate per annum compounded semi-annually. The amount of
interest payable on any Interest Payment Date shall be computed on the basis of
a 360-day year of twelve 30-day months and, for any period less than a full
calendar month, the number of days elapsed in such month. In the event that any
date on which the principal of (or premium, if any) or interest on this Security
is payable is not a Business Day, then the payment 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), with the same force and effect
as if made on such date. Pursuant to the Registration Rights Agreement, in
certain limited circumstances the Corporation will be required to pay Liquidated
Damages (as defined in the Registration Rights Agreement) with respect to this
Security.

            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, as defined in said Indenture) is registered at the close of business
on the regular record date for such interest installment, which shall be the
fifteenth day of the month which precedes the month in which the relevant
interest payment date falls. Any such interest installment not punctually paid
or duly provided for shall forthwith cease to be payable to the holders on such
regular record date and may be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on


                                       A-3
<PAGE>   95
a special record date to be fixed by the Trustee for the payment of such
defaulted interest, notice whereof shall be given to the holders of Securities
not less than 10 days prior to such special record date, or may be paid at any
time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

            The principal of (and premium, if any) and interest on this Security
shall be payable at the office or agency of the Trustee maintained for that
purpose in any coin or currency of the United States of America that at the time
of payment is legal tender for payment of public and private debts; provided,
however, that, payment of interest may be made at the option of the Corporation
by (i) check mailed to the holder at such address as shall appear in the
Security Register or (ii) by transfer to an account maintained by the Person
entitled thereto, provided that proper written transfer instructions have been
received by the relevant record date. Notwithstanding the foregoing, so long as
the Holder of this Security is the Property Trustee, the payment of the
principal of (and premium, if any) and interest on this Security will be made at
such place and to such account as may be designated by the Property Trustee.

            The indebtedness evidenced by this Security is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of Senior Indebtedness, 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 or her behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination so provided and (c) appoints the Trustee his or her
attorney-in-fact for any and all such purposes. Each holder hereof, by his or
her acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of
Senior Indebtedness, whether now outstanding or hereafter incurred, and waives
reliance by each such holder upon said provisions.

            This Security shall not be entitled to any benefit under the
Indenture hereinafter referred to, or be valid or become obligatory for any
purpose until the Certificate of Authentication hereon shall have been signed by
or on behalf of the Trustee.

hereof and such provisions shall for all purposes have the same effect as though
fully set forth at this place.

executed.

                          (FORM OF REVERSE OF SECURITY)

            This Security is one of the Securities of the Corporation (herein
sometimes referred to as the "Securities"), specified in the Indenture, all
issued or to be issued under and pursuant to an Indenture, dated as of January
31, 1997 (the "Indenture"), duly executed and delivered between the Corporation
and The Bank of New York, as Trustee (the "Trustee"), to which Indenture
reference is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Corporation
and the holders of the Securities.

            Upon the occurrence and continuation of a Special Event, the
Corporation shall have the right at any time, within 90 days following the
occurrence of a Special Event, prior to February 1, 2007 (the "Initial Optional
Redemption Date"), to redeem this Security in whole (but not in part) at the
Special Event Redemption Price. "Special Event Redemption Price" shall mean,
with respect to any redemption of the Securities following a Special Event, an
amount in cash equal to the greater of (i) 100% of the principal amount to be
redeemed or (ii) the sum, as determined by a Quotation Agent, of the present
values of the principal amount and premium payable with respect to an Optional

            The Optional Redemption Price or the Special Event Redemption Price,
as the case requires, shall be paid prior to 12:00 noon, New York time, on the
date of such redemption or at such earlier time as the Corporation determines,
provided, that the Corporation shall deposit with the Trustee an amount
sufficient to pay the applicable Redemption Price by 10:00 a.m., New York City
time, on the date such Redemption Price is to be paid. Any redemption pursuant
to this paragraph will be made upon not less than 30 days nor more than 60 days
notice. If the Securities are only partially redeemed by the Corporation
pursuant to an Optional Redemption, the Securities will be redeemed pro rata or
by lot or by any other method utilized by the Trustee; provided that if, at the
time of redemption, the Securities are registered as a Global Security, the
Depositary shall determine in accordance with its procedures the principal
amount of such Securities held for the account of its participants to be
redeemed.

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

            Notwithstanding the foregoing, any redemption of Securities by the
Corporation shall be subject to the receipt by the Corporation of any required
regulatory approval.

            In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Securities may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

            The Indenture contains provisions permitting the Corporation and the
Trustee, with the consent of the holders of a majority in aggregate principal
amount of the Securities at the time outstanding, as defined in the Indenture,
to execute supplemental indentures for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of the Indenture
or of modifying in any manner the rights of the holders of the Securities;
provided, however, that no such supplemental indenture shall, without the
consent of each holder of Securities then outstanding and affected thereby, (i)
extend the Maturity Date of any Securities, or reduce the principal amount
thereof, or reduce any amount payable on redemption thereof, or reduce the rate
or extend the time of payment of interest thereon (subject to Article XVI of the
Indenture), or make the principal of, or interest or premium on, the Securities
payable in any coin or currency other than U.S. dollars, or impair or affect the
right of

                                       A-7
<PAGE>   99
any holder of Securities to institute suit for the payment thereof, or (ii)
reduce the aforesaid percentage of Securities, the holders of which are required
to consent to any such supplemental indenture. The Indenture also contains
provisions permitting the holders of a majority in aggregate principal amount of
the Securities at the time outstanding, on behalf of all of the holders of the
Securities, to waive any past default in the performance of any of the covenants
contained in the Indenture, or established pursuant to the Indenture, and its
consequences, except a default in the payment of the principal of or premium, if
any, or interest on any of the Securities or a default in respect of any
covenant or provision under which the Indenture cannot be modified or amended
without the consent of each holder of Securities then outstanding. Any such
consent or waiver by the holder of this Security (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such Holder and upon all
future holders and owners of this Security and of any Security issued in
exchange herefor or in place hereof (whether by registration of transfer or
otherwise), irrespective of whether or not any notation of such consent or
waiver is made upon this Security.

            No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Corporation, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Security at the time and place and at the
rate and in the money herein prescribed.

            The Corporation shall have the right, at any time and from time to
time during the term of the Securities, to defer payments of interest by
extending the interest payment period of such Securities for a period not
exceeding 10 consecutive semi-annual periods, including the first such
semi-annual period during such extension period, and not to extend beyond the
Maturity Date of the Securities (an "Extended Interest Payment Period"), at the
end of which period the Corporation shall pay all interest then accrued and
unpaid (together with interest thereon at the rate specified for the Securities
to the extent that payment of such interest is enforceable under applicable
law). Before the termination of any such Extended Interest Payment Period, the
Corporation may further defer payments of interest by further extending such
Extended Interest Payment Period, provided that such Extended Interest Payment
Period, together with all such previous and further extensions within such
Extended Interest Payment Period, shall not exceed 10 consecutive semi-annual
periods, including the first semi-annual period during such Extended Interest
Payment Period, shall not end on any date other than an Interest Payment Date or
extend beyond the Maturity Date of the Securities. Upon the termination of any
such Extended Interest Payment Period and the payment of all accrued and unpaid
interest and any additional amounts then due, the Corporation may commence a new
Extended Interest Payment Period, subject to the foregoing requirements.

            The Corporation has agreed that it will not (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
(which includes common and preferred stock) or (ii) make any payment of
principal, interest or premium, if any, on or repay or repurchase or redeem any
debt securities of the Corporation that rank pari passu with or junior in right
of payment to the Securities or (iii) make any guarantee payments with respect
to any guarantee by the Corporation of any securities or any Subsidiary of the
Corporation (including Other Guarantees) if such guarantee ranks pari passu or
junior in right of payment to the Securities (other than (a) dividends or
distributions in shares of, or options, warrants or rights to subscribe for or
purchase shares of, Common Stock of the Corporation; (b) any declaration of a
dividend in connection with the implementation of a stockholder's rights plan,
or the issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto; (c) payments under the Capital
Securities Guarantee; (d) as a direct result of, and only to the extent required
in order to avoid the issuance of fractional shares of capital stock following a
reclassification of the Corporation's capital stock or the exchange or the
conversion of one class or series of the Corporation's capital stock for another
class or series of the Corporation's capital stock; (e) the purchase of
fractional interests in shares of the Corporation's capital stock pursuant to
the exchange or conversion of such capital stock or the security being exchanged
or converted and (f) 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 or any of the Corporation's dividend reinvestment plans)
if at such time (i) an Event of Default shall have occurred and be continuing,
(ii) there shall have occurred any event of which the Corporation has actual
knowledge that (a) is, or with the giving of notice or the lapse of time, or
both, would be, an Event of Default and (b) in respect of which the Corporation
shall not have taken reasonable steps to cure, (iii) if such Securities are held
by Peoples Heritage Capital Trust, the Corporation shall be in default with
respect to its payment obligations under the Capital Securities Guarantee or
(iv) the Corporation shall have given notice of its election of the exercise of
its right to extend the interest payment period and any such extension shall be
continuing.

            The Securities are issuable only in registered form without coupons
in denominations of $100,000.00 and integral multiples of $1,000 in excess
thereof. As provided in the Indenture and subject to the transfer restrictions
limitations as may be contained herein and therein from time to time, this
Security is transferable by the holder hereof on the Security Register of the
Corporation, upon surrender of this Security for registration of transfer at the
office or agency of the Corporation in the City and State of New York
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Corporation and the

                                       A-9
<PAGE>   101
Security registrar duly executed by the holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such transfer, but the Corporation may require payment of a sum
sufficient to cover any tax or other governmental charge payable in relation
thereto.

            Prior to due presentment for registration of transfer of this
Security, the Corporation, the Trustee, any authenticating agent, any paying
agent, any transfer agent and the registrar may deem and treat the holder hereof
as the absolute owner hereof (whether or not this Security shall be overdue and
notwithstanding any notice of ownership or writing hereon made by anyone other
than the Security Registrar) for the purpose of receiving payment of or on
account of the principal hereof and premium, if any, and (subject to the
Indenture) interest due hereon and for all other purposes, and neither the
Corporation nor the Trustee nor any authenticating agent nor any paying agent
nor any transfer agent nor any registrar shall be affected by any notice to the
contrary.

            No recourse shall be had for the payment of the principal of or
premium, if any, or interest on this Security, or for any claim based hereon, or
otherwise in respect hereof, or based on or in respect of the Indenture, against
any incorporator, stockholder, officer or director, past, present or future, as
such, of the Corporation or of any predecessor or successor Person, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

            All terms used in this Security that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

            THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT
OF LAW PROVISIONS THEREOF.

every purpose of this Declaration, but no such waiver shall extend to any
subsequent or other default or an Event of Default with respect to the Capital
Securities or impair any right consequent thereon. Any waiver by the Holders of
the Capital Securities of an Event of Default with respect to the Capital
Securities shall also be deemed to constitute a waiver by the Holders of the
Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Declaration without any further act, vote,
or consent of the Holders of the Common Securities.

         The Holders of a Majority in liquidation amount of the Capital
Securities shall have the right to direct the time, method and place of
conducting any proceeding for any remedy


                                       11
<PAGE>   17
available to the Property Trustee or to direct the exercise of any trust or
power conferred upon the Property Trustee, including the right to direct the
Property Trustee to exercise the remedies available to it as holder of the
Debentures, provided, however, that (subject to the provisions of Section 3.9)
the Property Trustee shall have the right to decline to follow any such
direction if the Property Trustee shall determine that the action so directed
would be unjustly prejudicial to the Holders not taking part in such direction
or if the Property Trustee, being advised by counsel, determines that the action
or proceeding so directed may not lawfully be taken or if the Property Trustee,
in good faith, by its board of directors or trustees, executive committee, or a
trust committee of directors or trustees and/or Responsible Officers, shall
determine that the action or proceedings so directed would involve the Property
Trustee in personal liability.

         (b)  The Holders of a Majority in liquidation amount of the Common
Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

         (i)  is not waivable under the Indenture, except where the Holders of
     the Common Securities are deemed to have waived such Event of Default under
     the Declaration as provided below in this Section 2.6(b), the Event of
     Default under the Declaration shall also not be waivable; or

         (ii) requires the consent or vote of a Super Majority to be waived,
     except where the Holders of the Common Securities are deemed to have waived
     such Event of Default under the Declaration as provided below in this
     Section 2.6(b), the Event of Default under the Declaration may only be
     waived by the vote of the Holders of at least the proportion in aggregate
     liquidation amount of the Common Securities that the relevant Super
     Majority represents of the aggregate principal amount of the Debentures
     outstanding;

provided further, each Holder of Common Securities will be deemed to have waived
any such Event of Default and all Events of Default with respect to the Common
Securities and its consequences if all Events of Default with respect to the
Capital Securities have been cured, waived or otherwise eliminated, and until
such Events of Default have been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the Holders of
the Capital Securities and only the Holders of the Capital Securities will have
the right to direct the Property Trustee in accordance with the terms of the
Securities. The foregoing provisions of this Section 2.6(b) shall be in lieu of
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are
hereby expressly excluded from this Declaration and the Securities, as permitted
by the Trust Indenture Act. Subject to the foregoing provisions of this Section
2.6(b), upon such waiver, any such default shall cease to exist and any Event of
Default with respect to the Common Securities arising therefrom shall be deemed
to have been cured for every purpose of this Declaration, but no such waiver
shall extend


                                       12
<PAGE>   18
to any subsequent or other default or Event of Default with respect to the
Common Securities or impair any right consequent thereon.

         (c)  A waiver of an Event of Default under the Indenture by the
Property Trustee, at the direction of the Holders of the Capital Securities,
constitutes a waiver of the corresponding Event of Default under this
Declaration. The foregoing provisions of this Section 2.6(c) shall be in lieu of
Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of
the Trust Indenture Act is hereby expressly excluded from this Declaration and
the Securities, as permitted by the Trust Indenture Act.

SECTION 2.7      Event of Default; Notice.

         (a)  The Property Trustee shall, within 90 days after the occurrence of
an Event of Default, transmit by mail, first class postage prepaid, to the
Holders of the Securities, notice of all defaults with respect to the Securities
actually known to a Responsible Officer of the Property Trustee, unless such
defaults have been cured before the giving of such notice (the term "defaults"
for the purposes of this Section 2.7(a) being hereby defined to be an Event of
Default as defined in the Indenture, not including any periods of grace provided
for therein and irrespective of the giving of any notice provided therein);
provided that, except for a default in the payment of principal of (or premium,
if any) or interest on any of the Debentures, the Property Trustee shall be
protected in withholding such notice if and so long as a Responsible Officer of
the Property Trustee in good faith determines that the withholding of such
notice is in the interests of the Holders.

         (b)  The Property Trustee shall not be deemed to have knowledge of any
default except:

         (i)  a default under Sections 5.01(a) and 5.01(b) of the Indenture
     relating to the Debentures; or

         (ii) any default as to which the Property Trustee shall have received
     written notice or of which a Responsible Officer of the Property Trustee
     charged with the administration of the Declaration shall have actual
     knowledge.

         (c)  Within ten 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 the Capital
Securities, the Administrative Trustees and the Sponsor, unless such Event of
Default shall have been cured or waived. The Sponsor and the Administrative
Trustees shall file annually with the Property Trustee in accordance with
Section 2.4 a certification as to whether or not they are in compliance with all
the conditions and covenants applicable to them under this Declaration.

Securities or to enable the Trust to effect the purposes for which the Trust was

otherwise cause the Capital Securities to be registered pursuant to an effective

SECTION 3.7      Prohibition of Actions by the Trust and the Trustees.

         (a)  The Trust shall not, and the Trustees (including the Property
Trustee) shall not, engage in any activity other than as required or authorized
by this Declaration. The Trust shall not:

         (i)   invest any proceeds received by the Trust from holding the
     Debentures, but shall distribute all such proceeds to Holders pursuant to
     the terms of this Declaration and of the Securities;

         (ii)  acquire any assets other than as expressly provided herein;

         (iii) possess Trust property for other than a Trust purpose;

         (iv)  make any loans or incur any indebtedness other than loans
     represented by the Debentures;

         (v)   possess any power or otherwise act in such a way as to vary the

     remedy


                                       18
<PAGE>   24
     available to the Debenture Trustee, or exercising any trust or power
     conferred upon the Debenture Trustee with respect to the Debentures, (B)
     waive any past default that is waivable under the Indenture, (C) exercise
     any right to rescind or annul any declaration that the principal of all the
     Debentures shall be due and payable, or (D) consent to any amendment,
     modification or termination of the Indenture or the Debentures where such
     consent shall be required unless the Trust shall have received an opinion
     of a nationally recognized independent tax counsel experienced in such
     matters to the effect that such modification will not cause more than an
     insubstantial risk that for United States federal income tax purposes the
     Trust will not be classified as a grantor trust.

SECTION 3.8      Powers and Duties of the Property Trustee.

         (a)  The legal title to the Debentures shall be owned by and held of
record in the name of the Property Trustee in trust for the benefit of the
Holders. The right, title and interest of the Property Trustee to the Debentures
shall vest automatically in each Person who may hereafter be appointed as
Property Trustee in accordance with Section 5.7. Such vesting and cessation of
title shall be effective whether or not conveyancing documents with regard to
the Debentures have been executed and delivered.

         (b)  The Property Trustee shall not transfer its right, title and
interest in the Debentures to the Administrative Trustees or to the Delaware
Trustee (if the Property Trustee does not also act as Delaware Trustee).

         (c)  The Property Trustee shall:

         (i)   establish and maintain a segregated non-interest bearing trust
     account (the "Property Trustee Account") in the name of and under the
     exclusive control of the Property Trustee on behalf of the Holders and,
     upon the receipt of payments of funds made in respect of the Debentures
     held by the Property Trustee, deposit such funds into the Property Trustee
     Account and make payments to the Holders of the Capital Securities and
     Holders of the Common Securities from the Property Trustee Account in
     accordance with Section 6.1. Funds in the Property Trustee Account shall be
     held uninvested until disbursed in accordance with this Declaration. The
     Property Trustee Account shall be an account that is maintained with a
     banking institution the rating on whose long-term unsecured indebtedness is
     at least equal to the rating assigned to the Capital Securities by a
     "nationally recognized statistical rating organization", as that term is
     defined for purposes of Rule 436(g)(2) under the Securities Act;

         (ii)  engage in such ministerial activities as shall be necessary or
     appropriate to effect the redemption of the Securities to the extent the
     Debentures are redeemed or mature; and


                                       19
<PAGE>   25
         (iii) upon written notice of distribution issued by the Administrative
     Trustees in accordance with the terms of the Securities, engage in such
     ministerial activities as shall be necessary or appropriate to effect the
     distribution of the Debentures to Holders of Securities upon the occurrence
     of certain events.

         (d)  The Property Trustee shall take all actions and perform such
duties as may be specifically required of the Property Trustee pursuant to the
terms of the Securities.

         (e)  Subject to Section 3.9(a), the Property Trustee shall take any
Legal Action which arises out of or in connection with an Event of Default of
which a Responsible Officer of the Property Trustee has actual knowledge or the
Property Trustee's duties and obligations under this Declaration or the Trust
Indenture Act. If an Event of Default has occurred and is continuing and such
event is attributable to the failure of the Debenture Issuer to pay the
principal of or premium, if any, or interest on the Debentures on the date such
principal, premium, if any, or interest is otherwise payable (or in the case of
redemption, on the redemption date), then a Holder of Capital Securities may
directly institute a proceeding for enforcement of payment to such Holder of the
principal of or premium, if any, or interest on the Debentures having a
principal amount equal to the aggregate liquidation amount of the Capital
Securities of such Holder (a "Direct Action") on or after the respective due
date specified in the Debentures. In connection with such Direct Action, the
rights of the Holders of the Common Securities will be subrogated to the rights
of such Holder of Capital Securities to the extent of any payment made by the
Debenture Issuer to such Holder of Capital Securities in such Direct Action.
Except as provided in the preceding sentence, the Holders of Capital Securities
will not be able to exercise directly any other remedy available to the holders
of the Debentures.

         (f)  The Property Trustee shall not resign as a Trustee unless either:

         (i)  the Trust has been completely liquidated and the proceeds of the
     liquidation distributed to the Holders pursuant to the terms of the
     Securities; or

         (ii) a successor Property Trustee has been appointed and has accepted
     that appointment in accordance with Section 5.7 (a "Successor Property
     Trustee").

         (g)  The Property Trustee shall have the legal power to exercise all of
the rights, powers and privileges of a holder of Debentures under the Indenture
and, if an Event of Default actually known to a Responsible Officer of the
Property Trustee occurs and is continuing, the Property Trustee shall, for the
benefit of Holders, enforce its rights as holder of the Debentures subject to
the rights of the Holders pursuant to the terms of such Securities.

         (h)  The Property Trustee shall be authorized to undertake any actions
set forth in Section 317(a) of the Trust Indenture Act.


                                       20
<PAGE>   26
         (i)  For such time as the Property Trustee is the Paying Agent, the
Property Trustee may authorize one or more Persons to act as additional Paying
Agents and to pay Distributions, redemption payments or liquidation payments on
behalf of the Trust with respect to all securities and any such Paying Agent
shall comply with Section 317(b) of the Trust Indenture Act. Any such additional
Paying Agent may be removed by the Property Trustee at any time the Property
Trustee remains as Paying Agent and a successor Paying Agent or additional
Paying Agents may be (but are not required to be) appointed at any time by the
Property Trustee while it is so acting as Paying Agent.

         (j)  Subject to this Section 3.8, the Property Trustee shall have none
of the duties, liabilities, powers or the authority of the Administrative
Trustees set forth in Section 3.6.

         The Property Trustee must exercise the powers set forth in this Section
3.8 in a manner that is consistent with the purposes and functions of the Trust
set out in Section 3.3, and the Property Trustee shall not take any action that
is inconsistent with the purposes and functions of the Trust set out in Section
3.3.

SECTION 3.9   Certain Duties and Responsibilities of the Property Trustee.

         (a)  The Property Trustee, before the occurrence of any Event of
Default and after the curing of all Trust Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Declaration and in the Securities and no implied covenants shall
be read into this Declaration against the Property Trustee. In case an Event of
Default has occurred (that has not been cured or waived pursuant to Section 2.6)
of which a Responsible Officer of the Property Trustee has actual knowledge, the
Property Trustee shall exercise such of the rights and powers vested in it by
this Declaration, 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 or her own affairs.

         (b)  No provision of this Declaration 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)  prior to the occurrence of an 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 Property Trustee shall be 
         determined solely by the express provisions of this Declaration and in
         the Securities and the Property Trustee shall not be liable except for
         the performance of such duties and obligations as are specifically set
         forth in this Declaration and in the Securities, and no implied
         covenants or obligations shall be read into this Declaration against
         the Property Trustee; and


                                       21
<PAGE>   27
              (B)  in the absence of bad faith on the part of the Property 
         Trustee, the Property 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 Property Trustee and
         conforming to the requirements of this Declaration; provided, however,
         that in the case of any such certificates or opinions that by any
         provision hereof are specifically required to be furnished to the
         Property Trustee, the Property Trustee shall be under a duty to examine
         the same to determine whether or not they conform to the requirements
         of this Declaration;

         (ii)  the Property Trustee shall not be liable for any error of

nor shall the Delaware Trustee have any of the duties and responsibilities of

SECTION 3.15     Mergers.

         (a)  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 Person, except as described in Section
3.15(b) and (c) and Section 3 of Annex I.

         (b)  The Trust may, at the request of the Sponsor, with the consent of
the Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees and without the consent of the Holders, the Delaware
Trustee or the Property Trustee, merge with or into, consolidate, amalgamate or
be replaced by, or convey, transfer or lease its properties and assets as an
entirety or substantially as an entirety to, a trust organized as such under the
laws of any State; provided that:

         (i)   such successor entity (the "Successor Entity") either:

              (A)  expressly assumes all of the obligations of the Trust under
         the Securities; or

              (B)  substitutes for the Securities other securities having 
         substantially the same terms as the Securities (the "Successor
         Securities") so long as the Successor Securities rank the same as the
         Securities rank with respect to Distributions and payments upon
         liquidation, redemption and otherwise;

         (ii)  the Sponsor expressly appoints a trustee of the Successor Entity
     that possesses the same powers and duties as the Property Trustee as the
     Holder of the Debentures;

         (iii) the Successor Securities are listed, or any Successor Securities
     will be listed upon notification of issuance, on any national securities
     exchange or with another organization on which the Capital Securities are
     then listed or quoted, if any;

         (iv)  such merger, consolidation, amalgamation, replacement,
     conveyance, transfer or lease does not cause the Capital Securities 
     (including any Successor Securities) to be downgraded by any nationally
     recognized statistical rating organization;


                                       26
<PAGE>   32
         (v)     such merger, consolidation, amalgamation, replacement,
     conveyance, transfer or lease does not adversely affect the rights,
     preferences and privileges of the Holders (including the holders of any
     Successor Securities) in any material respect (other than with respect to
     any dilution of such Holders' interests in the new entity);

         (vi)    such Successor Entity has a purpose substantially identical to
     that of the Trust;

         (vii)   prior to such merger, consolidation, amalgamation, replacement,
     conveyance, transfer or lease, the Sponsor has received an opinion of an
     independent counsel to the Trust 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 (including the holders of any
         Successor Securities) in any material respect (other than with respect
         to any dilution of the Holders' interest in the new entity); and

                 (B) following such merger, consolidation, amalgamation, 
         replacement, conveyance, transfer or lease, neither the Trust nor the
         Successor Entity will be required to register as an Investment Company;
         and

         (viii)  the Sponsor or any permitted successor or assignee 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 Capital Securities Guarantee and the
     Common Securities Guarantee.

         (c)  Notwithstanding Section 3.15(b), the Trust shall not, except with
the consent of Holders of 100% in liquidation amount of the Securities,
consolidate, amalgamate, merge with or into, or be replaced by, or convey,
transfer or lease its properties and assets as an entirety or 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 not to be classified as a grantor trust for United
States federal income tax purposes.

SECTION 4.3      Right to Proceed.

         The Sponsor acknowledges the rights of the Holders of Capital

Capital Securities is attributable to the failure of the Company to pay interest
or principal on the Debentures, to institute a proceeding directly against the
Debenture Issuer for enforcement of its payment obligations on the Debentures.

               (B)   until the assets of the Trust have been completely
         liquidated and the proceeds thereof distributed to the holders of the
         Securities; and

         (ii)  no such resignation of the Trustee that acts as the Delaware
     Trustee shall be effective until a Successor Delaware Trustee has been
     appointed and has accepted such appointment by instrument executed by such
     Successor Delaware Trustee and delivered to the Trust, the Sponsor and the
     resigning Delaware Trustee.

         (d)  The Holders of the Common Securities shall use their best efforts
to promptly appoint a Successor Delaware Trustee or Successor Property Trustee,
as the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with this Section 5.7.

         (e)  If no Successor Property Trustee or Successor Delaware Trustee
shall have been appointed and accepted appointment as provided in this Section
5.7 within 60 days after delivery of an instrument of resignation or removal,
the Property Trustee or Delaware Trustee resigning or being removed, as
applicable, may petition any court of competent jurisdiction for appointment of
a Successor Property Trustee or Successor Delaware Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper and
prescribe, appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be.

         (f)  No Property Trustee or Delaware Trustee shall be liable for the
acts or omissions to act of any Successor Property Trustee or successor Delaware
Trustee, as the case may be.

SECTION 5.8      Vacancies among Trustees.

         If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees is
increased pursuant to Section 5.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by the Administrative Trustees or, if
there are more than two, a majority of the Administrative Trustees shall be
conclusive evidence of the existence of such vacancy. The vacancy shall be
filled with a Trustee appointed in accordance with Section 5.7.

SECTION 5.9      Effect of Vacancies.

         The death, resignation, retirement, removal, bankruptcy, dissolution,
liquidation, incompetence or incapacity to perform the duties of a Trustee shall
not operate to dissolve, terminate or annul the Trust. Whenever a vacancy in the
number of Administrative Trustees shall occur, until such vacancy is filled by
the appointment of an Administrative Trustee in accordance with Section 5.7, the
Administrative Trustees in office, regardless of their number, shall have all
the powers granted to the Administrative Trustees


                                       33
<PAGE>   39
and shall discharge all the duties imposed upon the Administrative Trustees by
this Declaration.

SECTION 5.10     Meetings.

         If there is more than one Administrative Trustee, meetings of the
Administrative Trustees shall be held from time to time upon the call of any
Administrative Trustee. Regular meetings of the Administrative Trustees may be
held at a time and place fixed by resolution of the Administrative Trustees.
Notice of any in-person meetings of the Administrative Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 24 hours before such meeting. Notice of
any telephonic meetings of the Administrative Trustees or any committee thereof
shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before
a meeting. Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting. The presence (whether in person or by
telephone) of an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Declaration, any action of the Administrative
Trustees may be taken at a meeting by vote of a majority of the Administrative
Trustees present (whether in person or by telephone) and eligible to vote with
respect to such matter, provided that a Quorum is present, or without a meeting
by the unanimous written consent of the Administrative Trustees. In the event
there is only one Administrative Trustee, any and all action of such
Administrative Trustee shall be evidenced by a written consent of such
Administrative Trustee.

SECTION 5.11     Delegation of Power.

         (a)  Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
3.6, including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

         (b)  the Administrative Trustees shall have power to delegate from time
to time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

Section 5.12     Merger, Conversion, Consolidation or Succession to Business.

         Any Person into which the Property Trustee or the Delaware Trustee or
any Administrative Trustee that is not a natural person, as the case may be, may
be merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which the Property
Trustee or the Delaware Trustee, as the case may be, shall be a party, or any
Person succeeding to all or substantially all the corporate trust business of
the Property Trustee or the Delaware Trustee, as the case may be, shall be the
successor of the Property Trustee or the Delaware Trustee, as the case may be,
hereunder, provided such Person 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.


                                   ARTICLE VI
                                  DISTRIBUTIONS

SECTION 6.1      Distributions.

         Holders shall receive Distributions in accordance with the applicable
terms of the relevant Holder's Securities. If and to the extent that the
Debenture Issuer makes a payment of interest (including Compounded Interest (as
defined in the Indenture) and Additional Interest (as defined in the
Indenture)), premium and/or principal on the Debentures held by the Property
Trustee or Liquidated Damages (as defined in the Registration Rights Agreement)
or any other payments pursuant to the Registration Rights Agreement with respect
to the Debentures held by the Property Trustee (the amount of any such payment
being a "Payment Amount"), the Property Trustee shall and is directed, to the
extent funds are available for that purpose, to make a distribution (a
"Distribution") of the Payment Amount to Holders.

                                   ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1      General Provisions Regarding Securities.

         (a)  The Administrative Trustees shall on behalf of the Trust issue one
class of capital securities representing undivided beneficial interests in the
assets of the Trust having such terms as are set forth in Annex I (the "Series A
Capital Securities") and one class of common securities representing undivided
beneficial interests in the assets of the Trust having such terms as are set
forth in Annex I (the "Common Securities"). The Administrative Trustees shall on
behalf of the Trust issue one class of capital securities representing undivided
beneficial interests in the Trust having such terms as set forth in Annex I (the
"Series B Capital Securities") in exchange for Series A Capital Securities
accepted for exchange in the Exchange Offer, which Series B Capital Securities
shall not


                                       35
<PAGE>   41
bear the legends required by Section 9.2(i) unless the Holder of such Series A
Capital Securities is either (A) a broker-dealer who purchased such Series A
Capital Securities directly from the Trust for resale pursuant to Rule 144A or
any other available exemption under the Securities Act, (B) a Person
participating in the distribution of the Series A Capital Securities or (C) a
Person who is an affiliate (as defined in Rule 144A) of the Trust. The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Securities.

         (b)  The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

         (c)  Upon issuance of the Securities as provided in this Declaration,
the Securities so issued shall be deemed to be validly issued, fully paid and
non-assessable undivided beneficial interests in the assets of the Trust.

         (d)  Every Person, by virtue of having become a Holder or a Capital
Security Beneficial Owner in accordance with the terms of this Declaration,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by, this Declaration.

SECTION 7.2      Execution and Authentication.

         (a)  The Securities shall be signed on behalf of the Trust by an
Administrative Trustee. In case any Administrative Trustee of the Trust who
shall have signed any of the Securities shall cease to be such Administrative
Trustee before the Securities so signed shall be delivered by the Trust, such
Securities nevertheless may be delivered as though the person who signed such
Securities had not ceased to be such Administrative Trustee; and any Securities
may be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Administrative Trustees of the Trust,
although at the date of the execution and delivery of the Declaration any such
person was not such an Administrative Trustee.

         (b)  One Administrative Trustee shall sign the Capital Securities for
the Trust by manual or facsimile signature. Unless otherwise determined by the
Trust, such signature shall, in the case of Common Securities, be a manual
signature.

         A Capital Security shall not be valid until authenticated by the manual
signature of an authorized signatory of the Property Trustee. The signature
shall be conclusive evidence that the Capital Security has been authenticated
under this Declaration.

         Upon a written order of the Trust signed by one Administrative Trustee,
the Property Trustee shall authenticate the Capital Securities for original
issue. The aggregate


                                       36
<PAGE>   42
number of Capital Securities outstanding at any time shall not exceed the number
set forth in the Terms in Annex I hereto except as provided in Section 7.6.

         The Property Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Capital Securities. An authenticating agent may
authenticate Capital Securities whenever the Property Trustee may do so. Each
reference in this Declaration to authentication by the Property Trustee includes
authentication by such agent. An authenticating agent has the same rights as the
Property Trustee to deal with the Sponsor or an Affiliate.

SECTION 7.3      Form and Dating.

         The Capital Securities and the Property Trustee's certificate of
authentication shall be substantially in the form of Exhibit A-1 and the Common
Securities shall be substantially in the form of Exhibit A-2, each of which is
hereby incorporated in and expressly made a part of this Declaration.
Certificates representing the Securities may be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrative Trustees, as evidenced by their execution thereof. The
Securities may have letters, CUSIP or other numbers, notations or other marks of
identification or designation and such legends or endorsements required by law,
stock exchange rule, agreements to which the Trust is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Trust). The Trust at the direction of the Sponsor shall furnish any such
legend not contained in Exhibit A-1 to the Property Trustee in writing. Each
Capital Security shall be dated the date of its authentication. The terms and
provisions of the Securities set forth in Annex I and the forms of Securities
set forth in Exhibits A-1 and A-2 are part of the terms of this Declaration and
to the extent applicable, the Property Trustee and the Sponsor, by their
execution and delivery of this Declaration, expressly agree to such terms and
provisions and to be bound thereby.

         (a)  Global Securities. Securities offered and sold to QIBs in reliance
on Rule 144A or offered and sold outside of the United States to non-U.S.
persons in offshore transactions in reliance on Regulation S, as provided in the
Purchase Agreement, shall be issued in the form of one or more, permanent global
securities in definitive, fully registered form without distribution coupons
with the global legend and the applicable Restricted Securities Legend set forth
in Exhibit A-1 hereto (respectively, a "Rule 144A Global Capital Security" or
"Regulation S Global Capital Security," and each a "Global Capital Security" and
together the "Global Capital Securities"), which shall be deposited on behalf of
the purchasers of the Capital Securities represented thereby with the Clearing
Agency or with the Property Trustee, at its New York office, as custodian for
the Clearing Agency, and registered in the name of the Clearing Agency or a
nominee of the Clearing Agency, duly executed by the Trust and authenticated by
the Property Trustee as hereinafter provided. The number of Capital Securities
represented by the Rule 144A Global Capital Security and the Regulation S Global
Capital Security may from time to time be increased or decreased


                                       37
<PAGE>   43
by adjustments made on the records of the Property Trustee and the Clearing
Agency or its nominee as hereinafter provided.

         (b)  Book-Entry Provisions. This Section 7.3(b) shall apply only to the
Rule 144A Global Capital Securities, Regulation S Global Capital Securities and
such other Capital Securities in global form as may be authorized by the Trust
to be deposited with or on behalf of the Clearing Agency.

         The Trust shall execute and the Property Trustee shall, in accordance
with this Section 7.3, authenticate and make available for delivery initially
one or more Rule 144A Global Capital Securities and one or more Regulation S
Global Capital Securities that (i) shall be registered in the name of Cede & Co.
or other nominee of such Clearing Agency and (ii) shall be delivered by the
Trustee to such Clearing Agency or pursuant to such Clearing Agency's written
instructions or held by the Property Trustee as custodian for the Clearing
Agency.

         Members of, or participants in, the Clearing Agency ("Participants")
shall have no rights under this Declaration with respect to any Rule 144A Global
Capital Security or any Regulation S Global Capital Security held on their
behalf by the Clearing Agency or by the Property Trustee as the custodian of the
Clearing Agency or under such Rule 144A Global Capital Security or such
Regulation S Global Capital Security, and the Clearing Agency may be treated by
the Trust, the Property Trustee and any agent of the Trust or the Property
Trustee as the absolute owner of such Rule 144A Global Capital Security or such
Regulation S Global Capital Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Trust, the
Property Trustee or any agent of the Trust or the Property Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Clearing Agency or impair, as between the Clearing Agency and its
Participants, the operation of customary practices of such Clearing Agency
governing the exercise of the rights of a holder of a beneficial interest in any
Global Capital Security.

         (c)  Definitive Capital Securities. Except as provided in Section 7.9,
owners of beneficial interests in a Rule 144A Global Capital Security or a
Regulation S Global Capital Security will not be entitled to receive physical
delivery of certificated Capital Securities ("Definitive Capital Securities").
Purchasers of Securities who are "accredited investors" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act) and did not purchase
Capital Securities in reliance on Regulation S will receive Capital Securities
in the form of individual certificates in definitive, fully registered form
without distribution coupons and with the applicable Restricted Securities
Legend set forth in Exhibit A-1 hereto ("Restricted Definitive Capital
Securities"); provided, however, that upon transfer of such Restricted
Definitive Capital Securities to a QIB, such Restricted Definitive Capital
Securities will, unless the Rule 144A Global Capital Security has previously
been exchanged, be exchanged for an interest in a Rule 144A Global Capital
Security pursuant to the provisions of Section 9.2. Restricted Definitive
Capital Securities will bear the


                                       38
<PAGE>   44
applicable Restricted Securities Legend set forth on Exhibit A-1 unless removed
in accordance with this Section 7.3 or Section 9.2.

         (d)  The Capital Securities are issuable only in denominations of
$1,000.00 and any integral multiple thereof.

SECTION 7.4      Registrar, Paying Agent and Exchange Agent.

         The Trust shall maintain in the Borough of Manhattan, The City of New
York, (i) an office or agency where Capital Securities may be presented for
registration of transfer ("Registrar"), (ii) an office or agency where Capital
Securities may be presented for payment ("Paying Agent") and (iii) an office or
agency where Securities may be presented for exchange ("Exchange Agent"). The
Registrar shall keep a register of the Capital Securities and of their transfer.
The Trust may appoint the Registrar, the Paying Agent and the Exchange Agent and
may appoint one or more co-registrars, one or more additional paying agents and
one or more additional exchange agents in such other locations as it shall
determine. The term "Registrar" includes any additional registrar, "Paying
Agent" includes any additional paying agent and the term "Exchange Agent"
includes any additional exchange agent. The Trust may change any Paying Agent,
Registrar, co-registrar or Exchange Agent without prior notice to any Holder.
The Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Administrative Trustees. The Trust shall notify the
Property Trustee of the name and address of any Agent not a party to this
Declaration. If the Trust fails to appoint or maintain another entity as
Registrar, Paying Agent or Exchange Agent, the Property Trustee shall act as
such. The Trust or any of its Affiliates may act as Paying Agent, Registrar, or
Exchange Agent. The Trust shall act as Paying Agent, Registrar, co-registrar,
and Exchange Agent for the Common Securities.

         The Trust initially appoints the Property Trustee as Registrar, Paying
Agent, and Exchange Agent for the Capital Securities.

SECTION 7.5      Paying Agent to Hold Money in Trust.

         The Trust shall require each Paying Agent other than the Property
Trustee to agree in writing that the Paying Agent will hold in trust for the
benefit of Holders or the Property Trustee all money held by the Paying Agent
for the payment of liquidation amounts or Distributions on the Securities, and
will notify the Property Trustee if there are insufficient funds for such
purpose. While any such insufficiency continues, the Property Trustee may
require a Paying Agent to pay all money held by it to the Property Trustee. The
Trust at any time may require a Paying Agent to pay all money held by it to the
Property Trustee and to account for any money disbursed by it. Upon payment over
to the Property Trustee, the Paying Agent (if other than the Trust or an
Affiliate of the Trust) shall have no further liability for the money. If the
Trust or the Sponsor or an Affiliate of the Trust or the Sponsor acts as Paying
Agent, it shall segregate and hold in a separate trust fund for the benefit of
the Holders all money held by it as Paying Agent.


                                       39
<PAGE>   45
SECTION 7.6      Replacement Securities.

         If a Holder claims that a Security owned by it has been lost, destroyed
or wrongfully taken or if such Security is mutilated and is surrendered to the
Trust or in the case of the Capital Securities to the Property Trustee, the
Trust shall issue and the Property Trustee shall authenticate a replacement
Security if the Property Trustee's and the Trust's requirements, as the case may
be, are met. An indemnity bond must be provided by the Holder which, in the
judgment of the Property Trustee, is sufficient to protect the Trustees, the
Sponsor or any authenticating agent from any loss which any of them may suffer
if a Security is replaced. The Trust may charge such Holder for its expenses in
replacing a Security.

         Every replacement Security is an additional beneficial interest in the
Trust.

SECTION 7.7      Outstanding Capital Securities.

         The Capital Securities outstanding at any time are all the Capital
Securities authenticated by the Property Trustee except for those cancelled by
it, those delivered to it for cancellation and those described in this Section
as not outstanding.

         If a Capital Security is replaced, paid or purchased pursuant to
Section 7.6 hereof, it ceases to be outstanding unless the Property Trustee
receives proof satisfactory to it that the replaced, paid or purchased Capital
Security is held by a bona fide purchaser.

         If Capital Securities are considered paid in accordance with the terms
of this Declaration, they cease to be outstanding and Distributions on them
shall cease to accumulate.

         A Capital Security does not cease to be outstanding because one of the
Trust, the Sponsor or an Affiliate of the Sponsor holds the Security.

SECTION 7.8      Capital Securities in Treasury.

         In determining whether the Holders of the required amount of Securities
have concurred in any direction, waiver or consent, Capital Securities owned by
the Trust, the Sponsor or an Affiliate of the Sponsor, as the case may be, shall
be disregarded and deemed not to be outstanding, except that for the purposes of
determining whether the Property Trustee shall be fully protected in relying on
any such direction, waiver or consent, only Securities which the Property
Trustee actually knows are so owned shall be so disregarded.

SECTION 7.9      Temporary Securities.

         (a)  Until definitive Securities are ready for delivery, the Trust may
prepare and, in the case of the Capital Securities, the Property Trustee shall
authenticate


                                       40
<PAGE>   46
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Trust considers
appropriate for temporary Securities. Without unreasonable delay, the Trust
shall prepare and, in the case of the Capital Securities, the Property Trustee
shall authenticate definitive Securities in exchange for temporary Securities.

         (b)  A Global Capital Security deposited with the Clearing Agency or
with the Property Trustee as custodian for the Clearing Agency pursuant to
Section 7.3 shall be transferred to the beneficial owners thereof in the form of
definitive certificated Capital Securities only if such transfer complies with
Section 9.2 and (i) the Clearing Agency notifies the Company that it is
unwilling or unable to continue as Clearing Agency for such Global Capital
Security or if at any time such Clearing Agency ceases to be a "clearing agency"
registered under the Exchange Act and a clearing agency is not appointed by the
Sponsor within 90 days of such notice, (ii) a Default or an Event of Default has
occurred and is continuing or (iii) the Trust at its sole discretion elects to
cause the issuance of definitive certificated Capital Securities.

         (c)  Any Global Capital Security that is transferable to the beneficial
owners thereof in the form of definitive certificated Capital Securities
pursuant to this Section 7.9 shall be surrendered by the Clearing Agency to the
Property Trustee located in the Borough of Manhattan, The City of New York, to
be so transferred, in whole or from time to time in part, without charge, and
the Property Trustee shall authenticate and make available for delivery, upon
such transfer of each portion of such Global Capital Security, an equal
aggregate liquidation amount of Securities of authorized denominations in the
form of certificated Capital Securities. Any portion of a Global Capital
Security transferred pursuant to this Section shall be registered in such names
as the Clearing Agency shall direct. Any Capital Security in the form of
definitive certificated Capital Securities delivered in exchange for an interest
in the Restricted Capital Security in global form shall, except as otherwise
provided by Sections 7.3 and 9.2, bear the applicable Restricted Securities
Legend set forth in Exhibit A-1 hereto.

         (d)  Subject to the provisions of Section 7.9(c), the Holder of a
Global Capital Security may grant proxies and otherwise authorize any Person,
including Participants and Persons that may hold interests through Participants,
to take any action which such Holder is entitled to take under this Declaration
or the Securities.

         (e)  In the event of the occurrence of any of the events specified in
Section 7.9(b), the Trust will promptly make available to the Property Trustee a
reasonable supply of certificated Capital Securities in fully registered form
without distribution coupons.

SECTION 7.10     Cancellation.

         The Trust at any time may deliver Capital Securities to the Property
Trustee for cancellation. The Registrar, Paying Agent and Exchange Agent shall
forward to the


                                       41
<PAGE>   47
Property Trustee any Capital Securities surrendered to them for registration of
transfer, redemption, exchange or payment. The Property Trustee shall promptly
cancel all Capital Securities, surrendered for registration of transfer,
redemption, exchange, payment, replacement or cancellation and shall dispose of
cancelled Capital Securities as the Trust directs, provided that the Property
Trustee shall not be obligated to destroy Capital Securities. The Trust may not
issue new Capital Securities to replace Capital Securities that it has paid or
that have been delivered to the Property Trustee for cancellation or that any
Holder has exchanged.

SECTION 7.11     CUSIP Numbers.

         The Trust in issuing the Capital Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Property Trustee shall use "CUSIP"
numbers in notices of redemption as a convenience to Holders of Capital
Securities; provided that any such notice may state that no representation is
made as to the correctness of such numbers either as printed on the Capital
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 Capital
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Sponsor will promptly notify the Property Trustee
of any change in the CUSIP numbers.


                                  ARTICLE VIII
                              TERMINATION OF TRUST

SECTION 8.1      Termination of Trust.

         (a)  The Trust shall automatically terminate:

         (i)   upon the bankruptcy of the Sponsor;

         (ii)  upon the filing of a certificate of dissolution or liquidation or
     its equivalent with respect to the Sponsor; or the revocation of the
     Sponsor's charter and the expiration of 90 days after the date of
     revocation without a reinstatement thereof;

         (iii) following the distribution of a Like Amount of the Debentures to
     the Holders, provided that, the Property Trustee has received written
     notice from the Sponsor directing the Property Trustee to terminate the
     Trust (which direction is optional, and except as otherwise expressly
     provided below, within the discretion of the Sponsor) and provided,
     further, that such direction and such distribution is conditioned on (i)
     the receipt by the Sponsor or the Trust, as the case requires, of any
     required regulatory approval (including without limitation any required
     approval of the Federal Reserve Board) and (ii) the Administrative
     Trustees' receipt of an opinion of an independent tax counsel experienced
     in such matters (a "No


                                       42
<PAGE>   48
     Recognition Opinion"), which opinion may rely on published rulings of the
     Internal Revenue Service, to the effect that the Holders will not recognize
     any gain or loss for United States federal income tax purposes as a result
     of the dissolution of the Trust and the distribution of Debentures;

         (iv)  upon the entry of a decree of judicial dissolution of the Trust
     by a court of competent jurisdiction;

         (v)   when all of the Securities shall have been called for redemption
     and the amounts necessary for redemption thereof shall have been paid to
     the Holders in accordance with the terms of the Securities;

         (vi)  upon the repayment of the Debentures or at such time as no
     Debentures are outstanding; or

         (vii) the expiration of the term of the Trust provided in Section 3.14.

         (b)  As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a), the Administrative Trustees shall file a
certificate of cancellation with the Secretary of State of the State of
Delaware.

         (c)  The provisions of Section 3.9 and Article X shall survive the
termination of the Trust.


                                   ARTICLE IX
                              TRANSFER OF INTERESTS

SECTION 9.1      Transfer of Securities.

         (a)  Securities may only be transferred, in whole or in part, in
accordance with the terms and conditions set forth in this Declaration and in
the terms of the Securities. Any transfer or purported transfer of any Security
not made in accordance with this Declaration shall be null and void.

         (b)  Subject to this Article IX, Capital Securities may only be
transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Declaration. Any transfer or purported transfer of any
Security not made in accordance with this Declaration shall be null and void.

         (c)  The Sponsor may not transfer the Common Securities other than a
transfer in connection with a consolidation or merger of the Sponsor into
another Person, or any conveyance, transfer or lease by the Sponsor of its
properties and assets substantially as an entirety to any Person, pursuant to
the Indenture.

         (d)  The Administrative Trustees shall provide for the registration and
transfer of Securities (subject to Section 9.1(c) hereof in the case of the
Common Securities), which will be effected without charge but only upon payment
(with such indemnity as the Administrative Trustees may require) in respect of
any tax or other governmental charges that may be imposed in relation to it.
Upon surrender for registration of transfer of any Securities, the
Administrative Trustees shall cause one or more new Securities to be issued in
the name of the designated transferee or transferees. Every Security surrendered
for registration of transfer shall be accompanied by a written instrument of
transfer in form satisfactory to the Administrative Trustees duly executed by
the Holder or such Holder's attorney duly authorized in writing. Each Security
surrendered for registration of transfer shall be canceled by the Property
Trustee. A transferee of a Security shall be entitled to the rights and subject
to the obligations of a Holder hereunder upon the receipt by such transferee of
a Security. By acceptance of a Security, each transferee shall be deemed to have
agreed to be bound by this Declaration.

SECTION 9.2      Transfer Procedures and Restrictions

         (a)  General. Except as otherwise provided in Section 9.2(b), if
Capital Securities are issued upon the transfer, exchange or replacement of
Capital Securities bearing the Restricted Securities Legend set forth in Exhibit
A-1 hereto, or if a request is made to remove such Restricted Securities Legend
on Capital Securities, the Capital Securities so issued shall bear the
Restricted Securities Legend, or the Restricted Securities Legend shall not be
removed, as the case may be, unless there is delivered to the Trust and the
Property Trustee such evidence satisfactory to the Sponsor, which shall include
an Opinion of Counsel as may be reasonably required by the Sponsor, that neither
the legend nor the restrictions on transfer set forth therein are required to
ensure that transfers thereof are made pursuant to an exception from the
registration requirements of the Securities Act or, with respect to Restricted
Definitive Capital Securities, that such Securities are not "restricted" within
the meaning of Rule 144. Upon provision of such satisfactory evidence, the
Property Trustee, at the written direction of the Trust, shall authenticate and
deliver Capital Securities that do not bear the legend.

         (b)  Transfers After Effectiveness of a Registration Statement. After
the effectiveness of a Registration Statement with respect to any Capital
Securities, and except as otherwise required by applicable laws and regulations
or currently prevailing interpretations of the staff of the Commission, all
requirements pertaining to legends on such Capital Securities will cease to
apply, and beneficial interests in a Capital Security in global form without
legends will be available to transferees of such Capital Securities, upon
exchange of the transferring holder's Restricted Definitive Capital Security or
directions to transfer such Holder's beneficial interest in the Rule 144A Global
Capital Security or the Regulation S Global Capital Security, as the case may
be. No such transfer or exchange of a Restricted Definitive Capital Security or
of an interest in the Rule 144A Global Capital Security or the Regulation S
Global Capital Security shall be effective unless the transferor delivers to the
Trust a certificate in a form substantially similar to that attached hereto as


                                       44
<PAGE>   50
the "Form of Assignment" in Exhibit A-1. Except as otherwise provided in Section
9.2(l), after the effectiveness of a Registration Statement, the Trust shall
issue and the Property Trustee, upon a written order of the Trust signed by one
Administrative Trustee, shall authenticate a Capital Security in global form
without the Restricted Securities Legend (the "Unrestricted Global Capital
Security") for deposit with the Clearing Agency or its custodian to evidence
transfers of beneficial interests from the (i) Rule 144A Global Capital Security
or the Regulation S Global Capital Security and (ii) Restricted Definitive
Capital Securities.

         (c)  Transfer and Exchange of Definitive Capital Securities. When
Definitive Capital Securities are presented to the Registrar or co-Registrar

         (x) to register the transfer of such Definitive Capital Securities; or

         (y) to exchange such Definitive Capital Securities for an equal number
     of Definitive Capital Securities,

the Registrar or co-registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Definitive Capital Securities surrendered for
transfer or exchange:

         (i)   shall be duly endorsed or accompanied by a written instrument of
     transfer in form reasonably satisfactory to the Administrative Trustees and
     the Registrar or co-registrar, duly executed by the Holder thereof or his
     attorney duly authorized in writing; and

         (ii)  in the case of Definitive Capital Securities that are Restricted
     Definitive Capital Securities:

               (A)  if such Restricted Capital Securities are being delivered to
         the Registrar by a Holder for registration in the name of such Holder,
         without transfer, a certification from such Holder to that effect; or

               (B)  if such Restricted Capital Securities are being transferred:
         (i) a certification from the transferor in a form substantially similar
         to that attached hereto as the "Form of Assignment" in Exhibit A-1, and
         (ii) if the Trust so requests, evidence reasonably satisfactory to it
         as to the compliance with the restrictions set forth in the Restricted
         Securities Legend.

         (d)  Restrictions on Transfer of a Definitive Capital Security for a
Beneficial Interest in a Global Capital Security. A Definitive Capital Security
may not be exchanged for a beneficial interest in a Global Capital Security
except upon satisfaction of the requirements set forth below. Upon receipt by
the Property Trustee of a Definitive Capital Security, duly endorsed or
accompanied by appropriate instruments of transfer, in form satisfactory to the
Property Trustee and the Administrative Trustees, together with:


                                       45
<PAGE>   51
         (i)   if such Definitive Capital Security is a Restricted Capital
     Security, certification (in a form substantially similar to that attached
     hereto as the "Form of Assignment" in Exhibit A-1), provided, however, that
     such Definitive Capital Security may only be exchanged for an interest in a
     Regulation S Global Security where such Definitive Capital Security is
     being transferred pursuant to Regulation S or Rule 144 (if available); and

         (ii)  whether or not such Definitive Capital Security is a Restricted
     Capital Security, written instructions directing the Property Trustee to
     make, or to direct the Clearing Agency to make, an adjustment on its books
     and records with respect to the appropriate Global Capital Security to
     reflect an increase in the number of the Capital Securities represented by
     such Global Capital Security,

         then the Property Trustee shall cancel such Definitive Capital Security
         and cause, or direct the Clearing Agency to cause, the aggregate number
         of Capital Securities represented by the appropriate Global Capital
         Security to be increased accordingly. If no Global Capital Securities
         are then outstanding, the Trust shall issue and the Property Trustee
         shall authenticate, upon written order of any Administrative Trustee,
         an appropriate number of Capital Securities in global form.

         (e)  Transfer and Exchange of Global Capital Securities. Subject to
Section 9.2(f), the transfer and exchange of Global Capital Securities or
beneficial interests therein shall be effected through the Clearing Agency, in
accordance with this Declaration (including applicable restrictions on transfer
set forth herein, if any) and the procedures of the Clearing Agency therefor.

         (f)  Transfer of a Beneficial Interest in a Global Capital Security for
a Definitive Capital Security.

         (i)  Any Person having a beneficial interest in a Global Capital
     Security may upon request, but only upon 20 days prior notice to the
     Property Trustee, and if accompanied by the information specified below,
     exchange such beneficial interest for a Definitive Capital Security
     representing the same number of Capital Securities. Upon receipt by the
     Property Trustee from the Clearing Agency or its nominee on behalf of any
     Person having a beneficial interest in a Global Capital Security of written
     instructions or such other form of instructions as is customary for the
     Clearing Agency or the Person designated by the Clearing Agency as having
     such a beneficial interest in a Restricted Capital Security and a
     certification from the transferor (in a form substantially similar to that
     attached hereto as the "Form of Assignment" in Exhibit A-1), which may be
     submitted by facsimile, then the Property Trustee will cause the aggregate
     number of Capital Securities represented by Global Capital Securities to be
     reduced on its books and records and, following such reduction, the Trust
     will execute and the Property Trustee will authenticate and make available
     for delivery to the transferee a Definitive Capital Security.


                                       46
<PAGE>   52
         (ii) Definitive Capital Securities issued in exchange for a beneficial
     interest in a Global Capital Security pursuant to this Section 9.2(f) shall
     be registered in such names and in such authorized denominations as the
     Clearing Agency, pursuant to instructions from its Participants or indirect
     participants or otherwise, shall instruct the Property Trustee in writing.
     The Property Trustee shall deliver such Capital Securities to the persons
     in whose names such Capital Securities are so registered in accordance with
     such instructions of the Clearing Agency.

         (g)  Restrictions on Transfer and Exchange of Global Capital
Securities. Notwithstanding any other provisions of this Declaration (other than
the provisions set forth in subsection (b) of Section 7.9), a Global Capital
Security may not be transferred as a whole except by the Clearing Agency to a
nominee of the Clearing Agency or another nominee of the Clearing Agency or by
the Clearing Agency or any such nominee to a successor Clearing Agency or a
nominee of such successor Clearing Agency.

         Prior to the expiration of the restricted period, as contemplated by
Regulation S, beneficial interests in the Regulation S Global Capital Security
may be exchanged for beneficial interests in the Rule 144A Global Capital
Security only if such exchange occurs in connection with a transfer of the
Capital Securities pursuant to Rule 144A and the transferor first delivers to
the Property Trustee a written certificate (in a form substantially similar to
that attached hereto as the "Form of Assignment" in Exhibit A-1) to the effect
that the Capital Securities are being transferred to a Person who the transferor
reasonably believes is a QIB, purchasing for its own account or the account of a
QIB in a transaction meeting the requirements of Rule 144A and in accordance
with all applicable securities laws of the states of the United States and other
jurisdictions.

         Beneficial interests in the Rule 144A Global Capital Security may be
transferred to a person who takes delivery in the form of an interest in the
Regulation S Global Capital Security, whether before or after the expiration of
such restricted period, as contemplated by Regulation S, only if the transferor
first delivers to the Property Trustee a written certificate (in a form
substantially similar to that attached hereto as the "Form of Assignment" in
Exhibit A-1) to the effect that such transfer is being made in accordance with
Rule 903 or Rule 904 of Regulation S or Rule 144 (if available) and that, if
such transfer occurs prior to the expiration of such restricted period, the
interest transferred will be held immediately thereafter through the Euroclear
System or Cedel Bank, societe anonyme.

         (h)  Legend.

         (i)  Except as permitted by the following paragraph (ii), each Capital
     Security certificate evidencing the Global Capital Securities and the
     Definitive Capital Securities (and all Capital Securities issued in
     exchange therefor or substitution thereof) shall bear a legend (the
     "Restricted Securities Legend") in substantially the following form, as
     applicable:

                  EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
                  ACT IS AVAILABLE.

                  (ii)   Upon any sale or transfer of a Restricted Capital
         Security (including any Restricted Capital Security represented by a
         Global Capital Security) pursuant to an effective registration
         statement under the Securities Act or pursuant to Rule 144 under the
         Securities Act after such registration statement ceases to be
         effective:

                         (A)   in the case of any Restricted Capital Security
                  that is a Definitive Capital Security, the Registrar shall
                  permit the Holder thereof to exchange such Restricted Capital
                  Security for a Definitive Capital Security that does not bear
                  the Restricted Securities Legend and rescind any restriction
                  on the transfer of such Restricted Capital Security; and

<PAGE>   55
               (B)  in the case of any Restricted Capital Security that is
         represented by a Global Capital Security, the Registrar shall permit
         the Holder of such Global Capital Security to exchange such Global
         Capital Security for another Global Capital Security that does not bear
         the Restricted Securities Legend.

         (i)  Cancellation or Adjustment of Global Capital Security. At such
time as all beneficial interests in a Global Capital Security have either been
exchanged for Definitive Capital Securities to the extent permitted by this
Declaration or redeemed, repurchased or canceled in accordance with the terms of
this Declaration, such Global Capital Security shall be returned to the Property
Trustee for cancellation by the Property Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Capital Security is
exchanged for Definitive Capital Securities, Capital Securities represented by
such Global Capital Security shall be reduced and an adjustment shall be made on
the books and records of the Property Trustee (if it is then the custodian for
such Global Capital Security) with respect to such Global Capital Security, by
the Property Trustee or any Securities custodian, to reflect such reduction.

         (j)  Obligations with Respect to Transfers and Exchanges of Capital
Securities.

         (i)   To permit registrations of transfers and exchanges, the Trust

         (ii)  Registrations of transfers or exchanges will be effected without
     charge, but only upon payment (with such indemnity as the Trust or the
     Sponsor may require) in respect of any tax or other governmental charge
     that may be imposed in relation to it.

         (iii) The Registrar or co-registrar shall not be required to register
     the transfer of or exchange of (a) Capital Securities during a period
     beginning at the opening of business 15 days before the day of mailing of a
     notice of redemption or any notice of selection of Capital Securities for
     redemption and ending at the close of business on the day of such mailing;
     or (b) any Capital Security so selected for redemption in whole or in part,
     except the unredeemed portion of any Capital Security being redeemed in
     part.

         (iv)  Prior to the due presentation for registrations of transfer of
     any Capital Security, the Trust, the Property Trustee, the Paying Agent,
     the Registrar or any co-registrar may deem and treat the Person in whose 
     name a Capital Security is registered as the absolute owner of such Capital
     Security for the purpose of receiving Distributions on such Capital 
     Security (subject to Section 2(c) of Annex I) and for


                                       50
<PAGE>   56
     all other purposes whatsoever, and none of the Trust, the Property Trustee,
     the Paying Agent, the Registrar or any co-registrar shall be affected by
     notice to the contrary.

         (v)   All Capital Securities issued upon any transfer or exchange
     pursuant to the terms of this Declaration shall evidence the same security
     and shall be entitled to the same benefits under this Declaration as the
     Capital Securities surrendered upon such transfer or exchange.

         (k)  No Obligation of the Property Trustee.

         (i)   The Property Trustee shall have no responsibility or obligation 
     to any beneficial owner of a Global Capital Security, a Participant in the
     Clearing Agency or other Person with respect to the accuracy of the records
     of the Clearing Agency or its nominee or of any Participant thereof, with
     respect to any ownership interest in the Capital Securities or with respect
     to the delivery to any Participant, beneficial owner or other Person (other
     than the Clearing Agency) of any notice (including any notice of
     redemption) or the payment of any amount, under or with respect to such
     Capital Securities. All notices and communications to be given to the
     Holders and all payments to be made to Holders under the Capital Securities
     shall be given or made only to or upon the order of the registered Holders
     (which shall be the Clearing Agency or its nominee in the case of a Global
     Capital Security). The rights of beneficial owners in any Global Capital
     Security shall be exercised only through the Clearing Agency subject to the
     applicable rules and procedures of the Clearing Agency. The Property
     Trustee may conclusively rely and shall be fully protected in relying upon
     information furnished by the Clearing Agency or any agent thereof with
     respect to its Participants and any beneficial owners.

         (ii)  The Property Trustee and Registrar shall have no obligation or
     duty to monitor, determine or inquire as to compliance with any
     restrictions on transfer imposed under this Declaration or under applicable
     law with respect to any transfer of any interest in any Capital Security
     (including any transfers between or among Clearing Agency Participants or
     beneficial owners in any Global Capital Security) other than to require
     delivery of such certificates and other documentation or evidence as are
     expressly required by, and to do so if and when expressly required by, the
     terms of this Declaration, and to examine the same to determine substantial
     compliance as to form with the express requirements hereof.

         (l)  Exchange of Series A Capital Securities for Series B Capital
Securities. The Series A Capital Securities may be exchanged for Series B
Securities pursuant to the terms of the Exchange Offer. The Trustee shall make
the exchange as follows:

     The Sponsor shall present the Property Trustee with an Officers'
Certificate certifying the following:


                                       51
<PAGE>   57
         (A)     upon issuance of the Series B Capital Securities, the
                 transactions contemplated by the Exchange Offer have been
                 consummated; and

         (B)     the number of Series A Capital Securities properly tendered in
                 the Exchange Offer that are represented by a Global Capital
                 Security and the number of Series A Capital Securities properly
                 tendered in the Exchange Offer that are represented by
                 Definitive Capital Securities, the name of each Holder of
                 such Definitive Capital Securities, the liquidation amount of
                 Capital Securities properly tendered in the Exchange Offer by
                 each such Holder and the name and address to which Definitive
                 Capital Securities for Series B Capital Securities shall be
                 registered and sent for each such Holder.

     The Property Trustee, upon receipt of (i) such Officers' Certificate, (ii)
an Opinion of Counsel (x) to the effect that the Series B Capital Securities
have been registered under Section 5 of the Securities Act and the Indenture has
been qualified under the Trust Indenture Act and (y) with respect to the matters
set forth in Section 3(p) of the Registration Rights Agreement and (iii) a
Company Order, shall authenticate (A) a Global Capital Security for Series B
Capital Securities in aggregate liquidation amount equal to the aggregate
liquidation amount of Series A Capital Securities represented by a Global
Capital Security indicated in such Officers' Certificate as having been properly
tendered and (B) Definitive Capital Securities representing Series B Capital
Securities registered in the names of, and in the liquidation amounts indicated
in such Officers' Certificate.

     If, upon consummation of the Exchange Offer, less than all the outstanding
Series A Capital Securities shall have been properly tendered and not withdrawn,
the Property Trustee shall make an endorsement on the Global Capital Security
for Series A Capital Securities indicating the reduction in the number and
aggregate liquidation amount represented thereby as a result of the Exchange
Offer.

     The Trust shall deliver such Definitive Capital Securities for Series B
Capital Securities to the Holders thereof as indicated in such Officers'
Certificate.

         (m)  Minimum Transfers. Series A Capital Securities may only be
transferred in minimum blocks of $100,000 aggregate liquidation amount until

registration statement filed under the Securities Act.

SECTION 9.3      Book Entry Interests.

         Global Capital Securities shall initially be registered on the books
and records of the Trust in the name of Cede & Co., the nominee of the Clearing
Agency, and no Capital Security Beneficial Owner will receive a definitive
Capital Security certificate representing such Capital Security Beneficial
Owner's interests in such Global Capital Securities,

     the sole holder of the Global Certificates and shall have no obligation to
     the Capital Security Beneficial Owners;

         (c) to the extent that the provisions of this Section 9.4 conflict with

                           LIMITATION OF LIABILITY OF
                    HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1     Liability.

         (a)  Except as expressly set forth in this Declaration, the Securities
Guarantees and the terms of the Securities, the Sponsor shall not be:

         (i)  personally liable for the return of any portion of the capital
     contributions (or any return thereon) of the Holders of the Securities
     which shall be made solely from assets of the Trust; and

         (ii) be required to pay to the Trust or to any Holder of Securities any
     deficit upon dissolution or termination of the Trust or otherwise.

         (b)  The Sponsor shall be liable for all of the debts and obligations
of the Trust (other than with respect to the Securities) to the extent not
satisfied out of the Trust's assets.

         (c)  Pursuant to Section 3803(a) of the Business Trust Act, the Holders
of the Capital Securities 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.

SECTION 10.2     Exculpation.

         (a)  No Indemnified Person shall be liable, responsible or accountable
in damages or otherwise to the Trust or any Covered Person for any loss, damage
or claim incurred by reason of 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 the authority
conferred on such Indemnified Person by this Declaration or by law, except that
an Indemnified Person shall be liable for any such loss, damage or claim
incurred by reason of such Indemnified Person's gross negligence or willful
misconduct with respect to such acts or omissions.

         (b)  An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Trust and upon such information, opinions, reports
or statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and, if selected by such Indemnified Person, has been selected by
such Indemnified Person with reasonable care on behalf of the Trust, including
information, opinions, reports or statements as to the value and amount of the
assets, liabilities, profits, losses, or any other facts pertinent to the


                                       54
<PAGE>   60
existence and amount of assets from which Distributions to Holders of Securities
might properly be paid.

SECTION 10.3     Fiduciary Duty.

         (a)  To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for
its good faith reliance on the provisions of this Declaration. The provisions of
this Declaration, to the extent that they restrict the duties and liabilities of
an Indemnified Person otherwise existing at law or in equity (other than the
duties imposed on the Property Trustee under the Trust Indenture Act), are
agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person.

         (b)  Unless otherwise expressly provided herein:

         (i)  whenever a conflict of interest exists or arises between any
     Covered Persons and any Indemnified Persons; or

         (ii) whenever this Declaration or any other agreement contemplated
     herein or therein provides that an Indemnified Person shall act in a manner
     that is, or provides terms that are, fair and reasonable to the Trust or
     any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

         (c)  Whenever in this Declaration an Indemnified Person is permitted or
required to make a decision:

         (i)  in its "discretion" or under a grant of similar authority, the
     Indemnified Person shall be entitled to consider such interests and factors
     as it desires, including its own interests, and shall have no duty or
     obligation to give any consideration to any interest of or factors
     affecting the Trust or any other Person; or


                                       55
<PAGE>   61
         (ii)  in its "good faith" or under another express standard, the
     Indemnified Person shall act under such express standard and shall not be
     subject to any other or different standard imposed by this Declaration or
     by applicable law.

SECTION 10.4     Indemnification.

         (a)   (i) The Sponsor shall indemnify, to the full extent permitted by
     law, any Company Indemnified Person who was or is a party or is threatened
     to be made a party to any threatened, pending or completed action, suit or
     proceeding, whether civil, criminal, administrative or investigative (other
     than an action by or in the right of the Trust) by reason of the fact that
     he is or was a Company Indemnified Person against expenses (including
     attorneys' fees and expenses), judgments, fines and amounts paid in
     settlement actually and reasonably incurred by him in connection with such
     action, suit or proceeding if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     Trust, and, with respect to any criminal action or proceeding, had no
     reasonable cause to believe his conduct was unlawful. The termination of
     any action, suit or proceeding by judgment, order, settlement, conviction,
     or upon a plea of nolo contendere or its equivalent, shall not, of itself,
     create a presumption that the Company Indemnified Person did not act in
     good faith and in a manner which he reasonably believed to be in or not
     opposed to the best interests of the Trust, and, with respect to any
     criminal action or proceeding, had reasonable cause to believe that his
     conduct was unlawful.

         (ii)  The Sponsor shall indemnify, to the full extent permitted by law,
     any Company Indemnified Person who was or is a party or is threatened to be
     made a party to any threatened, pending or completed action or suit by or
     in the right of the Trust to procure a judgment in its favor by reason of
     the fact that he is or was a Company Indemnified Person against expenses
     (including attorneys' fees and expenses) actually and reasonably incurred
     by him in connection with the defense or settlement of such action or suit
     if he acted in good faith and in a manner he reasonably believed to be in
     or not opposed to the best interests of the Trust and except that no such
     indemnification shall be made in respect of any claim, issue or matter as
     to which such Company Indemnified Person shall have been adjudged to be
     liable to the Trust unless and only to the extent that the Court of
     Chancery of Delaware or the court in which such action or suit was brought
     shall determine upon application that, despite the adjudication of
     liability but in view of all the circumstances of the case, such person is
     fairly and reasonably entitled to indemnity for such expenses which such
     Court of Chancery or such other court shall deem proper.

         (iii) To the extent that a Company Indemnified Person shall be
     successful on the merits or otherwise (including dismissal of an action
     without prejudice or the settlement of an action without admission of
     liability) in defense of any action, suit or proceeding referred to in
     paragraphs (i) and (ii) of this Section 10.4(a), or in defense of any
     claim, issue or matter therein, he shall be indemnified, to the full extent


                                       56
<PAGE>   62
     permitted by law, against expenses (including attorneys' fees) actually and
     reasonably incurred by him in connection therewith.

         (iv)  Any indemnification under paragraphs (i) and (ii) of this Section
     10.4(a) (unless ordered by a court) shall be made by the Debenture Issuer
     only as authorized in the specific case upon a determination that
     indemnification of the Company Indemnified Person is proper in the
     circumstances because he has met the applicable standard of conduct set
     forth in paragraphs (i) and (ii). Such determination shall be made (1) by
     the Administrative Trustees by a majority vote of a quorum consisting of
     such Administrative Trustees who were not parties to such action, suit or
     proceeding, (2) if such a quorum is not obtainable, or, even if obtainable,
     if a quorum of disinterested Administrative Trustees so directs, by
     independent legal counsel in a written opinion, or (3) by the Common
     Security Holder of the Trust.

         (v)   Expenses (including attorneys' fees and expenses) incurred by a
     Company Indemnified Person in defending a civil, criminal, administrative
     or investigative action, suit or proceeding referred to in paragraphs (i)
     and (ii) of this Section 10.4(a) shall be paid by the Debenture Issuer in
     advance of the final disposition of such action, suit or proceeding upon
     receipt of an undertaking by or on behalf of such Company Indemnified
     Person to repay such amount if it shall ultimately be determined that he is
     not entitled to be indemnified by the Debenture Issuer as authorized in
     this Section 10.4(a). Notwithstanding the foregoing, no advance shall be
     made by the Debenture Issuer if a determination is reasonably and promptly
     made (i) by the Administrative Trustees by a majority vote of a quorum of
     disinterested Administrative Trustees, (ii) if such a quorum is not
     obtainable, or, even if obtainable, if a quorum of disinterested
     Administrative Trustees so directs, by independent legal counsel in a
     written opinion or (iii) the Common Security Holder of the Trust, that,
     based upon the facts known to the Administrative Trustees, counsel or the
     Common Security Holder at the time such determination is made, such Company
     Indemnified Person acted in bad faith or in a manner that such person did
     not believe to be in or not opposed to the best interests of the Trust, or,
     with respect to any criminal proceeding, that such Company Indemnified
     Person believed or had reasonable cause to believe his conduct was
     unlawful. In no event shall any advance be made in instances where the
     Administrative Trustees, independent legal counsel or Common Security
     Holder reasonably determine that such person deliberately breached his duty
     to the Trust or its Common or Capital Security Holders.

         (vi)  The indemnification and advancement of expenses provided by, or
     granted pursuant to, the other paragraphs of this Section 10.4(a) shall not
     be deemed exclusive of any other rights to which those seeking
     indemnification and advancement of expenses may be entitled under any
     agreement, vote of stockholders or disinterested directors of the Debenture
     Issuer or Capital Security Holders of the Trust or otherwise, both as to
     action in his official capacity and as to action in another capac-


                                       57
<PAGE>   63
     ity while holding such office. All rights to indemnification under this
     Section 10.4(a) shall be deemed to be provided by a contract between the
     Debenture Issuer and each Company Indemnified Person who serves in such
     capacity at any time while this Section 10.4(a) is in effect. Any repeal or
     modification of this Section 10.4(a) shall not affect any rights or
     obligations then existing.

         (vii)   The Sponsor or the Trust may purchase and maintain insurance on
     behalf of any person who is or was a Company Indemnified Person against any
     liability asserted against him and incurred by him in any such capacity, or
     arising out of his status as such, whether or not the Debenture Issuer
     would have the power to indemnify him against such liability under the
     provisions of this Section 10.4(a).

         (viii)  For purposes of this Section 10.4(a), references to "the Trust"
     shall include, in addition to the resulting or surviving entity, any
     constituent entity (including any constituent of a constituent) absorbed in
     a consolidation or merger, so that any person who is or was a director,
     trustee, officer or employee of such constituent entity, or is or was
     serving at the request of such constituent entity as a director, trustee,
     officer, employee or agent of another entity, shall stand in the same
     position under the provisions of this Section 10.4(a) with respect to the
     resulting or surviving entity as he would have with respect to such
     constituent entity if its separate existence had continued.

         (ix)    The indemnification and advancement of expenses provided by, or
     granted pursuant to, this Section 10.4(a) shall, unless otherwise provided
     when authorized or ratified, continue as to a person who has ceased to be a
     Company Indemnified Person and shall inure to the benefit of the heirs,
     executors and administrators of such a person.

         (b)  The Sponsor agrees to indemnify the (i) Property Trustee, (ii) the
Delaware Trustee, (iii) any Affiliate of the Property Trustee and the Delaware
Trustee, and (iv) any officers, directors, shareholders, members, partners,
employees, representatives, custodians, nominees or agents of the Property
Trustee and the Delaware Trustee (each of the Persons in (i) through (iv) being
referred to as a "Fiduciary Indemnified Person") for, and to hold each Fiduciary
Indemnified Person harmless against, any and all loss, liability, damage, claim
or expense including taxes (other than taxes based on the income of such
Fiduciary Indemnified Person) incurred without negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration of
the trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against or investigating
any claim or liability in connection with the exercise or performance of any of
its powers or duties hereunder. The obligation to indemnify as set forth in this
Section 10.4(b) shall survive the termination of this Declaration.

SECTION 10.5     Outside Businesses.

         Any Covered Person, the Sponsor, the Delaware Trustee and the Property
Trustee (subject to Section 5.3(c)) 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 shall have no rights by virtue of this Declaration 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. No Covered Person, the Sponsor, the Delaware
Trustee, or the Property 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 any
Covered Person, the Sponsor, the Delaware Trustee and the Property 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 Covered Person, the Delaware Trustee and the Property Trustee
may engage or be interested in any financial or other transaction with the
Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee
or agent for, or act on any committee or body of holders of, securities or other
obligations of the Sponsor or its Affiliates.

SECTION 10.6     Compensation; Fees.

     The Sponsor 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); and

         (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
Declaration (including the reasonable compensation and the expenses and
disbursements of their respective agents and counsel), except any such expense,
disbursement or advance as may be attributable to its negligence or bad faith.

         The provisions of this Section 10.6 shall survive the dissolution of
the Trust and the termination of this Declaration and the removal or resignation
of any Trustee.

         No Trustee may claim any lien or charge on any property of the Trust as
a result of any amount due pursuant to this Section 10.6.

SECTION 11.1     Fiscal Year.

         The fiscal year ("Fiscal Year") of the Trust shall be the calendar
year, or such other year as is required by the Code.

SECTION 11.2     Certain Accounting Matters.

         (a)  At all times during the existence of the Trust, the Administrative
Trustees shall keep, or cause to be kept, full books of account, records and
supporting documents, which shall reflect in reasonable detail, each transaction
of the Trust. The books of account shall be maintained on the accrual method of
accounting, in accordance with generally accepted accounting principles,
consistently applied. The Trust shall use the accrual method of accounting for
United States federal income tax purposes. The books of account and the records
of the Trust shall be examined by and reported upon as of the end of each Fiscal
Year of the Trust by a firm of independent certified public accountants selected
by the Administrative Trustees.

         (b)  The Administrative Trustees shall cause to be prepared and
delivered to each of the Holders, within 90 days after the end of each Fiscal
Year of the Trust, annual financial statements of the Trust, including a balance
sheet of the Trust as of the end of such Fiscal Year, and the related statements
of income or loss;

         (c)  The Administrative Trustees shall cause to be duly prepared and
delivered to each of the Holders, any annual United States federal income tax
information statement, required by the Code, containing such information with
regard to the Securities held by each Holder as is required by the Code and the
Treasury Regulations. Notwithstanding any right under the Code to deliver any
such statement at a later date, the Administrative Trustees shall endeavor to
deliver all such information statements within 30 days after the end of each
Fiscal Year of the Trust.

         (d)  The Administrative Trustees shall cause to be duly prepared and
filed with the appropriate taxing authority, an annual United States federal
income tax return, on a Form 1041 or such other form required by United States
federal income tax law, and any other annual income tax returns required to be
filed by the Administrative Trustees on behalf of the Trust with any state or
local taxing authority.

SECTION 11.3     Banking.

         The Trust shall maintain one or more bank accounts in the name and for
the sole benefit of the Trust; provided, however, that all payments of funds in

the Property Trustee


                                       60
<PAGE>   66
Account and no other funds of the Trust shall be deposited in the Property
Trustee Account. The sole signatories for such accounts shall be designated by
the Administrative Trustees; provided, however, that the Property Trustee shall
designate the signatories for the Property Trustee Account.

SECTION 11.4     Withholding.

         The Trust and the Administrative Trustees shall comply with all
withholding requirements under United States federal, state and local law. The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably be
requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations. The Administrative Trustees shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions. To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to Distributions or allocations to any Holder, the amount withheld shall
be deemed to be a Distribution in the amount of the withholding to the Holder.
In the event of any claimed over withholding, Holders shall be limited to an
action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

<PAGE>   68
         (i)   cure any ambiguity, correct or supplement any provision in this
     Declaration that may be inconsistent with any other provision of this
     Declaration or to make any other provisions with respect to matters or
     questions arising under this Declaration which shall not be inconsistent
     with the other provisions of the Declaration;

         (ii)  to modify, eliminate or add to any provisions of the Declaration
     to such extent as shall be necessary to ensure that the Trust will be

     Trust will not be required to register as an Investment Company under the
     Investment Company Act; or

         (iii) to modify, eliminate or add any provisions of the Declaration to
     such extent as shall be necessary to enable the Trust and the Sponsor to

     Rights Agreement;

provided, however, that in the case of clauses (i) and (iii), such action shall
not adversely affect in any material respect the interests of the Holders, and
any amendments of this Declaration shall become effective when notice thereof is
given to the Holders.

SECTION 12.2     Meetings of the Holders; Action by Written Consent.

         (a)  Meetings of the Holders of any class of Securities may be called
at any time by the Administrative Trustees (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Declaration, the terms of
the Securities or the rules of any stock exchange on which the Capital
Securities are listed or admitted for trading. The Administrative Trustees shall
call a meeting of the Holders of such class if directed to do so by the Holders
of at least 10% in liquidation amount of such class of Securities. Such
direction shall be given by delivering to the Administrative Trustees one or
more notices in a writing stating that the signing Holders of Securities wish to
call a meeting and indicating the general or specific purpose for which the
meeting is to be called. Any Holders calling a meeting shall specify in writing
the Security Certificates held by the Holders exercising the right to call a
meeting and only those Securities specified shall be counted for purposes of
determining whether the required percentage set forth in the second sentence of
this paragraph has been met.

         (b)  Except to the extent otherwise provided in the terms of the
Securities, the following provisions shall apply to meetings of Holders of
Securities:

         (i)   notice of any such meeting shall be given to all the Holders of
     Securities having a right to vote thereat at least seven days and not more
     than 60 days before the date of such meeting. Whenever a vote, consent or
     approval of the Holders is permitted or required under this Declaration or
     the rules of any stock


                                       63
<PAGE>   69
     exchange on which the Capital Securities are listed or admitted for
     trading, such vote, consent or approval may be given at a meeting of the
     Holders. Any action that may be taken at a meeting of the Holders of
     Securities may be taken without a meeting if a consent in writing setting
     forth the action so taken is signed by the Holders of Securities owning not
     less than the minimum amount of Securities in liquidation amount that would
     be necessary to authorize or take such action at a meeting at which all
     Holders having a right to vote thereon were present and voting. Prompt
     notice of the taking of action without a meeting shall be given to the
     Holders entitled to vote who have not consented in writing. The
     Administrative Trustees may specify that any written ballot submitted to
     the Security Holder for the purpose of taking any action without a meeting
     shall be returned to the Trust within the time specified by the
     Administrative Trustees;

         (ii)    each Holder may authorize any Person to act for it by proxy on
     all matters in which a Holder is entitled to participate, including waiving
     notice of any meeting, or voting or participating at a meeting. No proxy
     shall be valid after the expiration of 11 months from the date thereof
     unless otherwise provided in the proxy. Every proxy shall be revocable at
     the pleasure of the Holder of Securities executing it. Except as otherwise
     provided herein, all matters relating to the giving, voting or validity of
     proxies shall be governed by the General Corporation Law of the State of
     Delaware relating to proxies, and judicial interpretations thereunder, as
     if the Trust were a Delaware corporation and the Holders were stockholders
     of a Delaware corporation;

         (iii)   each meeting of the Holders shall be conducted by the
     Administrative Trustees or by such other Person that the Administrative
     Trustees may designate; and

         (iv)    unless the Business Trust Act, this Declaration, the terms of
     the Securities, the Trust Indenture Act or the listing rules of any stock
     exchange on which the Capital Securities are then listed or trading,
     otherwise provides, the Administrative Trustees, in their sole discretion,
     shall establish all other provisions relating to meetings of Holders,
     including notice of the time, place or purpose of any meeting at which any
     matter is to be voted on by any Holders of Securities, waiver of any such
     notice, action by consent without a meeting, the establishment of a record
     date, quorum requirements, voting in person or by proxy or any other matter
     with respect to the exercise of any such right to vote.

                                     ANNEX I


                                    TERMS OF
                   9.06% SERIES A/SERIES B CAPITAL SECURITIES
                             9.06% COMMON SECURITIES


         Pursuant to Section 7.1 of the Amended and Restated Declaration of
Trust, dated as of January 31, 1997 (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Securities are set out below (each
capitalized term used but not defined herein has the meaning set forth in the
Declaration or, if not defined in such Declaration, as defined in the Offering
Memorandum referred to below in Section 2(c) of this Annex I):

         1.   Designation and Number.

         (a)  Capital Securities. 100,000 Series A Capital Securities of the
Trust and 100,000 Series B Capital Securities of the Trust, each series with an
aggregate liquidation amount with respect to the assets of the Trust of one
hundred million dollars ($100,000,000), and each with a liquidation amount with
respect to the assets of the Trust of $1,000 per security, are hereby designated
for the purposes of identification only as "9.06% Series A Capital Securities"
and "9.06% Series B Capital Securities", respectively (collectively, the
"Capital Securities"). The certificates evidencing the Capital Securities shall
be substantially in the form of Exhibit A-1 to the Declaration, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice or to conform to the rules of any stock
exchange on which the Capital Securities are listed.

         (b)  Common Securities. 3,093 Common Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of three
million and ninety-three thousand dollars ($3,093,000) and a liquidation amount
with respect to the assets of the Trust of $1,000 per security, are hereby
designated for the purposes of identification only as "9.06% Common Securities"
(the "Common Securities"). The certificates evidencing the Common Securities
shall be substantially in the form of Exhibit A-2 to the Declaration, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice.

         2.   Distributions.

         (a)  Distributions payable on each Security will be fixed at a rate per
annum of 9.06% (the "Coupon Rate") of the liquidation amount of $1,000 per
Security (the "Liquidation Amount"), such rate being the rate of interest
payable on the Debentures to be held by the Property Trustee. Distributions in
arrears for more than one semi-annual period will bear additional distributions
thereon compounded semi-annually at the Coupon


                                       I-1
<PAGE>   76
Rate (to the extent permitted by applicable law). Pursuant to the Registration
Rights Agreement, in certain limited circumstances the Debenture Issuer will be
required to pay Liquidated Damages (as defined in the Registration Rights
Agreement) with respect to the Debentures. The term "Distributions", as used
herein, includes distributions of any such interest and Liquidated Damages
payable unless otherwise stated. A Distribution is payable only to the extent
that payments are made in respect of the Debentures held by the Property Trustee
and to the extent the Property Trustee has funds on hand legally available
therefor.

         (b)  Distributions on the Securities will be cumulative, will
accumulate from the most recent date to which Distributions have been paid or
duly provided for or, if no Distributions have been paid or duly provided for,
from January 31, 1997, and will be payable semi-annually in arrears on February
1 and August 1 of each year, commencing on August 1, 1997 (each, a "Distribution
Date"), except as otherwise described below. Distributions will be computed on
the basis of a 360-day year consisting of twelve 30-day months and for any
period less than a full calendar month on the basis of the actual number of days
elapsed in such month. As long as no Event of Default has occurred and is
continuing under the Indenture, the Debenture Issuer has the right under the
Indenture to defer payments of interest by extending the interest payment period
at any time and from time to time on the Debentures for a period not exceeding
10 consecutive semi-annual periods, including the first such semi-annual period
during such period (each an "Extension Period"), during which Extension Period
no interest shall be due and payable on the Debentures, provided that no
Extension Period shall extend beyond the Maturity Date of the Debentures. As a
consequence of such deferral, Distributions will also be deferred. Despite such
deferral, Distributions will continue to accumulate with additional
Distributions thereon (to the extent permitted by applicable law but not at a
rate greater than the rate at which interest is then accruing on the Debentures)
at the Coupon Rate compounded semi-annually during any such Extension Period.
Prior to the termination of any such Extension Period, the Debenture Issuer may
further defer payments of interest by further extending such Extension Period;
provided that such Extension Period, together with all such previous and further
extensions within such Extension Period, may not exceed 10 consecutive
semi-annual periods, including the first semi-annual period during such
Extension Period, or extend beyond the Maturity Date of the Debentures. Upon the
termination of any Extension Period and the payment of all amounts then due, the
Debenture Issuer may commence a new Extension Period, subject to the above
requirements.

         (c)  Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the fifteenth
day of the month which precedes the month in which the relevant Distribution
Date occurs, which Distribution Dates correspond to the interest payment dates
on the Debentures. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment in respect of the Global
Capital Securities will be made as described under the heading "Description of
the Capital Securities -- Form, Denomination, Book-Entry Procedures and
Transfer" in the Offering Memorandum dated January 29, 1997, of the Debenture
Issuer and the Trust relating to the Securities and the Debentures. Payments in
respect of Capital Securities held


                                       I-2
<PAGE>   77
in certificated form will be made by check mailed to the Holder entitled
thereto. The relevant record dates for the Common Securities shall be the same
as the record dates for the Capital Securities. Distributions payable on any
Securities that are not punctually paid on any Distribution Date, as a result of
the Debenture Issuer having failed to make a payment under the Debentures, will
cease to be payable to the Holder on the relevant record date, and such
defaulted Distribution will instead be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with the Indenture. If any date on which Distributions
are payable on the Securities is not a Business Day, then 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 of any
such delay), with the same force and effect as if made on such date.

         (d)  In the event that there is any money or other property held by or
for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders of the Securities.

         3.   Liquidation Distribution Upon Dissolution.

         In the event of any termination of the Trust or the Sponsor otherwise
gives notice of its election to liquidate the Trust pursuant to Section
8.1(a)(iii) of the Declaration, the Trust shall be liquidated by the
Administrative Trustees as expeditiously as the Administrative Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to the Holders a Like
Amount (as defined below) of the Debentures, unless such distribution is
determined by the Property Trustee not to be practicable, in which event such
Holders will be entitled to receive out of the assets of the Trust legally
available for distribution to Holders, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, an amount equal to the
aggregate of the liquidation amount of $1,000 per Security plus accumulated and
unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution").

         "Like Amount" means (i) with respect to a redemption of the Securities,
Securities having a Liquidation Amount equal to the principal amount of
Debentures to be paid in accordance with their terms and (ii) with respect to a
distribution of Debentures upon the liquidation of the Trust, Debentures having
a principal amount equal to the Liquidation Amount of the Securities of the
Holder to whom such Debentures are distributed.

         If, upon any such liquidation, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets on hand legally available
to pay in full the aggregate Liquidation Distribution, then the amounts payable
directly by the Trust on the Securities shall be paid on a Pro Rata basis.


                                      I-3
<PAGE>   78
         4.   Redemption and Distribution.

         (a)  Upon the repayment of the Debentures in whole or in part, at
maturity or upon early redemption (either at the option of the Debenture Issuer
or pursuant to a Special Event, as described below), the proceeds from such
repayment shall be simultaneously applied by the Property Trustee (subject to
the Property Trustee having received notice no later than 45 days prior to such
repayment) to redeem a Like Amount of the Securities at a redemption price equal
to (i) in the case of the repayment of the Debentures at maturity, the Maturity
Redemption Price (as defined below), (ii) in the case of the optional redemption
of the Debentures upon the occurrence and continuation of a Special Event, the
Special Event Redemption Price (as defined below) and (iii) in the case of the
optional redemption of the Debentures other than as a result of the occurrence
and continuance of a Special Event, the Optional Redemption Price (as defined
below). The Maturity Redemption Price, the Special Event Redemption Price and
the Optional Redemption Price are referred to collectively as the "Redemption
Price". Holders will be given not less than 30 nor more than 60 days notice of
such redemption.

         (b)  (i) The "Maturity Redemption Price", with respect to a redemption
of Securities, shall mean an amount equal to the principal of and accrued and
unpaid interest on the Debentures as of the maturity date thereof.

         (ii) In the case of an optional redemption, if fewer than all the
outstanding Securities are to be so redeemed, the Capital Securities will be
redeemed Pro Rata and the Capital Securities to be redeemed will be determined
as described in Section 4(f)(ii) below. Upon the entry of an order for the
dissolution of the Trust by a court of competent jurisdiction, the Debentures
thereafter will be subject to optional repayment, in whole, but not in part, on
or after February 1, 2007 (the "Initial Optional Redemption Date").

         The Debenture Issuer shall have the right (subject to the conditions in
the Indenture) to elect to redeem the Debentures in whole or in part at any time
on or after the Initial Optional Redemption Date, upon not less than 30 days and
not more than 60 days notice, at the Optional Redemption Price and, simultaneous
with such redemption, to cause a Like Amount of the Securities to be redeemed by
the Trust at the Optional Redemption Price on a Pro Rata basis. "Optional
Redemption Price" shall mean a price equal to the percentage of the liquidation
amount of Securities to be redeemed plus accumulated and unpaid Distributions
thereon, if any, to the date of such redemption if redeemed during the 12-month
period beginning February 1 of the years indicated below:

         (c)  If at any time a Tax Event or a Regulatory Capital Event (each as
defined below, and each a "Special Event") occurs, the Debenture Issuer shall
have the right (subject to the conditions set forth in the Indenture) at any
time prior to the Initial Optional Redemption Date, upon not less than 30 nor
more than 60 days notice, to redeem the Debentures in whole, but not in part,
within the 90 days following the occurrence of such Special Event (the "90 Day
Period"), and, simultaneous with such redemption, to cause a Like Amount of the
Securities to be redeemed by the Trust at the Special Event Redemption Price on
a Pro Rata basis.

         "Tax Event" shall occur upon receipt by the Sponsor and the
Administrative Trustee of an opinion (a "Tax Event Opinion") of a
nationally-recognized tax counsel experienced in such matters to the effect
that, as a result of any amendment to, or change (including any announced
prospective 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 pronouncement or decision is announced on or after January
31, 1997, there is more than an insubstantial risk that (i) the Trust 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 Debentures,
(ii) interest payable by the Debenture Issuer on the Debentures is not, or
within 90 days of the date of such opinion, will not be, deductible by the
Debenture Issuer, in whole or in part, for United States federal income tax
purposes, or (iii) the Trust 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.

         "Regulatory Capital Event" shall occur at any time that the Debenture
Issuer shall have received an opinion of independent bank regulatory counsel
experienced in such matters to the effect that, as a result of (a) any amendment
to, or change (including any announced prospective change) in, the laws (or any
regulations thereunder) of the United


                                       I-5
<PAGE>   80
States or any rules, guidelines or policies of the Federal Reserve Board or (b)
any official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
such pronouncement or decision is announced on or after January 31, 1997, the
Capital Securities do not constitute, or within 90 days of the date thereof,
will not constitute, Tier I Capital (or its then equivalent); provided, however,
that the distribution of the Junior Subordinated Debentures in connection with a
termination of the Trust by the Corporation shall not in and of itself
constitute a Regulatory Capital Event.

         "Special Event Redemption Price" shall mean, with respect to a
redemption of Securities, a price equal to the greater of (i) 100% of the
principal of a Like Amount of Debentures to be redeemed or (ii) the sum, as
determined by a Quotation Agent (as defined in the Indenture), of the present
values of the principal amount and premium payable with respect to an optional
redemption of a Like Amount of the Debentures on the Initial Optional Redemption
Date, together with scheduled payments of interest on the Debentures from the
redemption date to and including the Initial Optional Redemption Date,
discounted to the redemption date on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as
defined in the Indenture), plus, in either case, accumulated and unpaid
Distributions thereon, if any, to the date of such redemption.

         (d)  On and from the date fixed by the Administrative Trustees for any
distribution of Debentures and liquidation of the Trust: (i) the Securities will
no longer be deemed to be outstanding, (ii) the Clearing Agency or its nominee
(or any successor Clearing Agency or its nominee), as the Holder of the Capital
Securities, will receive a registered global certificate or certificates
representing the Debentures to be delivered upon such distribution and any
certificates representing Securities not held by the Clearing Agency or its
nominee (or any successor Clearing Agency or its nominee) will be deemed to
represent beneficial interests in a Like Amount of Debentures until such
certificates are presented to the Debenture Issuer or its agent for transfer or
reissue.

         (e)  The Trust may not redeem fewer than all the outstanding Securities
unless all accumulated and unpaid Distributions have been paid on all Securities
for all semi-annual Distribution periods terminating on or before the date of
redemption.

         (f)  The procedure with respect to redemptions or distributions of
Debentures shall be as follows:

         (i)  Notice of any redemption of, or notice of distribution of
     Debentures in exchange for, the Securities (a "Redemption/Distribution
     Notice") will be given by the Trust by mail to each Holder to be redeemed
     or exchanged not fewer than 30 nor more than 60 days before the date fixed
     for redemption or exchange thereof which, in the case of a redemption, will
     be the date fixed for redemption of the Debentures. For purposes of the
     calculation of the date of redemption or exchange and the dates


                                       I-6
<PAGE>   81
     on which notices are given pursuant to this Section 4(f)(i), a Redemption/
     Distribution Notice shall be deemed to be given on the day such notice is
     first mailed by first-class mail, postage prepaid, to Holders. Each
     Redemption/Distribution Notice shall be addressed to the Holders of
     Securities at the address of each such Holder appearing in the books and
     records of the Trust. No defect in the Redemption/Distribution Notice or in
     the mailing of either thereof with respect to any Holder shall affect the
     validity of the redemption or exchange proceedings with respect to any
     other Holder.

         (ii)  In the event that fewer than all the outstanding Securities are
     to be redeemed, the Securities to be redeemed shall be redeemed Pro Rata
     from each Holder of Capital Securities, it being understood that, in
     respect of Capital Securities registered in the name of and held of record
     by the Clearing Agency or its nominee (or any successor Clearing Agency or
     its nominee) or any nominee, the distribution of the proceeds of such
     redemption will be made to the Clearing Agency and disbursed by such
     Clearing Agency in accordance with the procedures applied by such agency or
     nominee.

         (iii) If Securities are to be redeemed and the Trust gives a
     Redemption/Distribution Notice, (which notice will be irrevocable), then
     (A) with respect to Capital Securities issued in book-entry form, by 12:00
     noon, New York City time, on the redemption date, provided that the
     Debenture Issuer has paid the Property Trustee a sufficient amount of cash
     in connection with the related redemption or maturity of the Debentures by
     10:00 a.m., New York City time, on the maturity date or the date of
     redemption, as the case requires, the Property Trustee will deposit
     irrevocably with the Clearing Agency or its nominee (or successor Clearing
     Agency or its nominee) funds sufficient to pay the applicable Redemption
     Price with respect to such Capital Securities and will give the Clearing
     Agency irrevocable instructions and authority to pay the Redemption Price
     to the relevant Clearing Agency Participants, and (B) with respect to
     Capital Securities issued in certificated form and Common Securities,
     provided that the Debenture Issuer has paid the Property Trustee a
     sufficient amount of cash in connection with the related redemption or
     maturity of the Debentures, the Property Trustee will pay the relevant
     Redemption Price to the Holders by check mailed to the address of the
     relevant Holder appearing on the books and records of the Trust on the
     redemption date. If a Redemption/Distribution Notice shall have been given
     and funds deposited as required, if applicable, then immediately prior to
     the close of business on the date of such deposit, or on the redemption
     date, as applicable, Distributions will cease to accumulate on the
     Securities so called for redemption and all rights of Holders so called for
     redemption will cease, except the right of the Holders of such Securities
     to receive the Redemption Price, but without interest on such Redemption
     Price, and such Securities shall cease to be outstanding.


                                       I-7
<PAGE>   82
         (iv)  Payment of accumulated and unpaid Distributions on the Redemption
     Date of the Securities will be subject to the rights of Holders of
     Securities on the close of business on a regular record date in respect of
     a Distribution Date occurring on or prior to such Redemption Date.

     Neither the Administrative Trustees nor the Trust shall be required to
register or cause to be registered the transfer of (i) any Securities beginning
on the opening of business 15 days before the day of mailing of a notice of
redemption and ending at the close of business on the day of such mailing or
(ii) any Securities selected for redemption except the unredeemed portion of any
Security being redeemed. If any date fixed for redemption of Securities 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), with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
in respect of any Securities is improperly withheld or refused and not paid
either by the Property Trustee or by the Sponsor as guarantor pursuant to the
relevant Securities Guarantee, Distributions on such Securities will continue to
accumulate from the original redemption date to the actual date of payment, in
which case the actual payment date will be considered the date fixed for
redemption for purposes of calculating the Redemption Price.

         (v)   Redemption/Distribution Notices shall be sent by the Property
     Trustee on behalf of the Trust to (A) in respect of the Capital Securities,
     the Clearing Agency or its nominee (or any successor Clearing Agency or its
     nominee) if the Global Certificates have been issued or, if Definitive
     Capital Security Certificates have been issued, to the Holder thereof, and
     (B) in respect of the Common Securities to the Holder thereof.

         (vi)  Subject to the foregoing and applicable law (including, without
     limitation, United States federal securities laws and banking laws),
     provided the acquiror is not the Holder of the Common Securities or the
     obligor under the Indenture, the Sponsor or any of its subsidiaries may at
     any time and from time to time purchase outstanding Capital Securities by
     tender, in the open market or by private agreement.

         5.   Voting Rights - Capital Securities.

         (a)  Except as provided under Sections 5(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Capital Securities will
have no voting rights.

         (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 such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.07 of
the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures or (iv)


                                       I-8
<PAGE>   83
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 a majority in liquidation amount
of all outstanding Capital 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 approval of each Holder of the Capital Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of the Capital Securities except by subsequent vote of such Holders. Subject to
Section 2.7 of the Declaration, the Property Trustee shall notify each Holder of
Capital Securities of any notice of default with respect to the Debentures. In
addition to obtaining the foregoing approvals of such Holders of the Capital
Securities, prior to taking any of the foregoing actions, the Trustees shall
obtain an opinion of counsel experienced in such matters to the effect that the
Trust will not be classified as an association taxable as a corporation for
United States federal income tax purposes on account of such action.

         If an Event of Default under the Declaration has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay principal of or premium, if any, or interest on the Debentures on the due
date (or in the case of redemption, on the redemption date), then a Holder of
Capital Securities may directly institute a proceeding for enforcement of
payment to such Holder of the principal of or premium, if any, or interest on a
Like Amount of Debentures (a "Direct Action") on or after the respective due
date specified in the Debentures. In connection with such Direct Action, the
rights of the Common Securities Holder will be subrogated to the rights of such
Holder of Capital Securities to the extent of any payment made by the Debenture
Issuer to such Holder of Capital Securities in such Direct Action. Except as
provided in the second preceding sentence and in Section 3.8(e) of the
Declaration, the Holders of Capital Securities will not be able to exercise
directly any other remedy available to the holders of the Debentures.

         Any approval or direction of Holders of Capital Securities may be given
at a separate meeting of Holders of Capital Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Administrative Trustees will cause a notice of
any meeting at which Holders of Capital Securities are entitled to vote, or of
any matter upon which action by written consent of such Holders is to be taken,
to be mailed to each Holder of record of Capital Securities. Each such notice
will include a statement setting forth (i) the date of such meeting or the date
by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which written consent is sought and (iii) instructions
for the delivery of proxies or consents.

         No vote or consent of the Holders of the Capital Securities will be
required for the Trust to redeem and cancel Capital Securities or to distribute
the Debentures in accordance with the Declaration and the terms of the
Securities.


                                      I-9
<PAGE>   84
         Notwithstanding that Holders of Capital Securities are entitled to vote
or consent under any of the circumstances described above, any of the Capital
Securities that are owned by the Sponsor or any Affiliate of the Sponsor shall
not be entitled to vote or consent and shall, for purposes of such vote or
consent, be treated as if they were not outstanding.

         6.   Voting Rights - Common Securities.

         (a)  Except as provided under Sections 6(b), 6(c) and 7 as otherwise
required by law and the Declaration, the Holders of the Common Securities will
have no voting rights.

         (b)  Unless an Event of Default shall have occurred and be continuing,
any Trustee may be removed at any time by the Holder of the Common Securities.
If an 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 Capital Securities. In no event will the
Holders of the Capital Securities have the right to vote to appoint, remove or
replace the Administrative Trustees, which voting rights are vested exclusively
in the Sponsor as the holder of the Common Securities. No resignation or removal
of a 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 Declaration.

         (c)  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 such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.07 of
the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures 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 a majority in liquidation amount
of all outstanding Common 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 approval of each Holder of the Common Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of the Common Securities except by subsequent vote of such Holders. Subject to
Section 2.7 of the Declaration, the Property Trustee shall notify each Holder of
Common Securities of any notice of default with respect to the Debentures. In
addition to obtaining the foregoing approvals of such Holders of the Common
Securities, prior to taking any of the foregoing actions, the Trustees shall
obtain an opinion of counsel experienced in such matters to the effect that the
Trust will not be classified as an association taxable as a corporation for
United States federal income tax purposes on account of such action.


                                      I-10
<PAGE>   85
         If an Event of Default under the Declaration has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay principal of or premium, if any, or interest on the Debentures on the due
date (or in the case of redemption, on the redemption date), then a Holder of
Common Securities may institute a Direct Action for enforcement of payment to
such Holder of the principal of or premium, if any, or interest on a Like Amount
of Debentures on or after the respective due date specified in the Debentures.
In connection with Direct Action, the rights of the Common Securities Holder
will be subordinated to the rights of such Holder of Capital Securities to the
extent of any payment made by the Debenture Issuer to such Holder of Common
Securities in such Direct Action. Except as provided in the second preceding
sentence, the Holders of Common Securities will not be able to exercise directly
any other remedy available to the holders of the Debentures.

         Any approval or direction of Holders of Common Securities may be given
at a separate meeting of Holders of Common Securities convened for such purpose,
at a meeting of all of the Holders of Securities in the Trust or pursuant to
written consent. The Administrative Trustees will cause a notice of any meeting
at which Holders of Common Securities are entitled to vote, or of any matter
upon which action by written consent of such Holders is to be taken, to be
mailed to each Holder of record of Common Securities. Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consents.

         No vote or consent of the Holders of the Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
the Debentures in accordance with the Declaration and the terms of the
Securities.

         7.   Amendments to Declaration and Indenture.

         In addition to the requirements set out in Section 12.1 of the
Declaration, the Declaration may be amended from time to time by the Sponsor,
the Property Trustee and the Administrative Trustees, without the consent of the
Holders of the Securities (i) to cure any ambiguity, correct or supplement any
provisions in the Declaration that may be inconsistent with any other
provisions, or to make any other provisions with respect to matters or questions
arising under the Declaration which shall not be inconsistent with the other
provisions of the Declaration, (ii) to modify, eliminate or add to any
provisions of the Declaration to such extent as shall be necessary to ensure
that the Trust will be classified for United States federal income tax purposes
as a grantor trust at all times that any Securities are outstanding or to ensure
that the Trust will not be required to register as an "Investment Company" under
the Investment Company Act or (iii) to modify, eliminate or add any provisions
of the Declaration to such extent as shall be necessary to enable the Trust and
the Sponsor to conduct an Exchange Offer in the manner contemplated by the
Registration Rights Agreement; provided, however, that in the case of clauses
(i) and (iii),


                                      I-11
<PAGE>   86
such action shall not adversely affect in any material respect the interests of
any Holder of Securities, and any amendments of the Declaration shall become
effective when notice thereof is given to the holders of the Securities. Under
the circumstances referred to in Section 12.1(c) of the Declaration, the
Declaration may be amended by the Trustees and the Sponsor with (i) the consent
of Holders representing a majority in liquidation amount of all outstanding
Securities, 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 for United States federal income tax purposes or the Trust's
exemption from status as an Investment Company under the Investment Company Act,
provided that, without the consent of each Holder of Trust Securities, the
Declaration 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.

         8.  Pro Rata.

         A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
according to the aggregate liquidation amount of the Securities held by the
relevant Holder in relation to the aggregate liquidation amount of all
Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the Capital
Securities pro rata according to the aggregate liquidation amount of Capital
Securities held by the relevant Holder relative to the aggregate liquidation
amount of all Capital Securities outstanding, and only after satisfaction of all
amounts owed to the Holders of the Capital Securities, to each Holder of Common
Securities pro rata according to the aggregate liquidation amount of Common
Securities held by the relevant Holder relative to the aggregate liquidation
amount of all Common Securities outstanding. In any such proration, the Trust
may make such adjustments as may be appropriate in order that only Securities in
authorized denominations shall be redeemed (subject to the minimum block
requirements of Section 9.2(m) of the Declaration).

         9.  Ranking.

         The Capital Securities rank pari passu with the Common Securities and
payment thereon shall be made Pro Rata with the Common Securities, except that,
if an Event of Default under the Declaration occurs and is continuing, no
payments in respect of Distributions on, or payments upon liquidation,
redemption or otherwise with respect to, the Common Securities shall be made
until the Holders of the Capital Securities shall be paid in full the
Distributions, Redemption Price, Liquidation Distribution and other payments to
which they are entitled at such time.

<PAGE>   87
         10.  Acceptance of Securities Guarantee and Indenture.

         Each Holder of Capital Securities and Common Securities, by the
acceptance thereof, agrees to the provisions of the Capital Securities Guarantee
and the Common Securities Guarantee, respectively, including the subordination
provisions therein and to the provisions of the Indenture.


         11.  No Preemptive Rights.

         The Holders of the Securities shall have no preemptive rights to
subscribe for any additional securities.

         12.  Miscellaneous.

         These terms constitute a part of the Declaration.

         The Sponsor will provide a copy of the Declaration, the Capital
Securities Guarantee or the Common Securities Guarantee (as may be appropriate)

                          [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Capital Security will be fixed at a rate
per annum of 9.06% (the "Coupon Rate") of the liquidation amount of $1,000 per
Capital Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee. Distributions in arrears for more than one
semi-annual period will bear interest thereon compounded semi-annually at the
Coupon Rate (to the extent permitted by applicable law). Pursuant to the
Registration Rights Agreement, in certain limited circumstances the Debenture
Issuer will be required to pay Liquidated Damages (as defined in the
Registration Rights Agreement) with respect to the Debentures. The term
"Distributions," as used herein, includes such cash distributions and any such
interest and such Liquidated Damages payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds on hand legally available therefor.

         Distributions on the Capital Securities will be cumulative, will
accumulate from the most recent date to which Distributions have been paid or
duly provided for or, if no Distributions have been paid or duly provided for,
from January 31, 1997 and will be payable semi-annually in arrears, on February
1 and August 1 of each year, commencing on August 1, 1997, except as otherwise
described below. Distributions will be computed on the basis of a 360-day year
consisting of twelve 30-day months and, for any period less than a full calendar
month, the number of days elapsed in such month. As long as no Event of Default
has occurred and is continuing under the Indenture, the Debenture Issuer has the
right under the Indenture to defer payments of interest by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 10 consecutive calendar semi-annual periods, including
the first such semi-annual period during such extension period (each an
"Extension Period"), provided that no Extension Period shall end on a day other
than an Interest Payment Date for the Debentures or shall extend beyond the
Maturity Date of the Debentures. As a consequence of such deferral,
Distributions also will be deferred. Despite such deferral, semi-annual
Distributions will continue to accumulate with interest thereon (to the extent
permitted by applicable law, but not at a rate exceeding the rate of interest
then accruing on the Debentures) at the Coupon Rate compounded semi-annually
during any such Extension Period. Prior to the termination of any such Extension
Period, the Debenture Issuer may further defer payments of interest by further
extending such Extension Period; provided that such Extension Period, together
with all such previous and further extensions within such Extension Period, may
not exceed 10 consecutive semi-annual periods, including the first semi-annual
period during such Extension Period, or extend beyond the Maturity Date of the
Debentures. Payments of accumulated Distributions will be payable to Holders as
they appear on the books and records of the Trust on the first record date
preceding the end of the Extension Period. Upon the termination of any Extension
Period and the payment of all amounts then due, the Debenture Issuer may
commence a new Extension Period, subject to the above requirements.

         Subject to the Spronsor obtaining any prior regulatory approval then
required and to certain other conditions set forth in the Declaration and the
Indenture, the Property Trustee may, at the direction of the Sponsor, at any
time terminate the Trust and, after satisfaction of any liabilities to creditors
of the Trust in accordance with applicable law, cause the Debentures to be
distributed to the holders of the Securities in liquidation of the Trust or,
simultaneous with any redemption of the Debentures, cause a Like Amount of the
Securities to be redeemed by the Trust.

         The Capital Securities shall be redeemable as provided in the
Declaration.

                          [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Common Security will be fixed at a rate
per annum of 9.06% (the "Coupon Rate") of the liquidation amount of $1,000 per
Common Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee. Distributions in arrears for more than one
semi-annual period will bear interest thereon compounded semi-annually at the
Coupon Rate (to the extent permitted by applicable law). Pursuant to the
Registration Rights Agreement, in certain limited circumstances the Debenture
Issuer will be required to pay Liquidated Damages (as defined in the
Registration Rights Agreement) with respect to the Debentures. The term
"Distributions," as used herein, includes such cash distributions and any such
interest and such Liquidated Damages payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds available therefor.

         Distributions on the Common Securities will be cumulative, will accrue
from the most recent date to which Distributions have been paid or duly provided
for or, if no Distributions have been paid or duly provided for, from January
31, 1997 and will be payable semi-annually in arrears, on February 1 and August
1 of each year, commencing on August 1, 1997, except as otherwise described
below. Distributions will be computed on the basis of a 360-day year consisting
of twelve 30-day months and, for any period less than a full calendar month, the
number of days elapsed in such month. As long as no Event of Default has
occurred and is continuing under the Indenture, the Debenture Issuer has the
right under the Indenture to defer payments of interest by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 10 consecutive calendar semi-annual periods, including
the first such semi-annual period during such extension period (each an
"Extension Period"), provided that no Extension Period shall end on a day other
than an Interest Payment Date for the Debentures or shall extend beyond the
Maturity Date of the Debentures. As a consequence of such deferral,
Distributions also will be deferred. Despite such deferral, Distributions will
continue to accumulate with interest thereon (to the extent permitted by
applicable law, but not at a rate exceeding the rate of interest then accruing
on the Debentures) at the Coupon Rate compounded semi-annually during any such
Extension Period. Prior to the termination of any such Extension Period, the
Debenture Issuer may further defer payments of interest by further extending
such Extension Period; provided that such Extension Period, together with all

                          [FORM OF REVERSE OF SECURITY]

            Distributions payable on each Capital Security will be fixed at a
rate per annum of 9.06% (the "Coupon Rate") of the liquidation amount of $1,000
per Capital Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one semi-annual period will bear interest thereon compounded semi-annually
at the Coupon Rate (to the extent permitted by applicable law). A Distribution
is payable only to the extent that payments are made in respect of the
Debentures held by the Property Trustee and to the extent the Property Trustee
has funds on hand legally available therefor.

            Distributions on the Capital Securities will be cumulative, will
accumulate from the most recent date to which Distributions have been paid or
duly provided for or, if no Distributions have been paid or duly provided for,
from January 31, 1997 and will be payable semi-annually in arrears, on February
1 and August 1 of each year, commencing on August 1, 1997, except as otherwise
described below. Distributions will be computed on the basis of a 360-day year
consisting of twelve 30-day months and, for any period less than a full calendar
month, the number of days elapsed in such month. As long as no Event of Default
has occurred and is continuing under the Indenture, the Debenture Issuer has the
right under the Indenture to defer payments of interest by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 10 consecutive calendar semi-annual periods, including
the first such semi-annual period during such extension period (each an
"Extension Period"), provided that no Extension Period shall end on a day other
than an Interest Payment Date for the Debentures or shall extend beyond the
Maturity Date of the Debentures. As a consequence of such deferral,
Distributions also will be deferred. Despite such deferral, semi-annual
Distributions will continue to accumulate with interest thereon (to the extent
permitted by applicable law, but not at a rate exceeding the rate of interest
then accruing on the Debentures) at the Coupon Rate compounded semi-annually
during any such Extension Period. Prior to the termination of any such Extension
Period, the Debenture Issuer may further defer payments of interest by further
extending such Extension Period; provided that such Extension Period, together
with all such previous and further extensions within such Extension Period, may
not exceed 10 consecutive semi-annual periods, including the first semi-annual
period during such Extension Period, or extend beyond the Maturity Date of the
Debentures. Payments of accumulated Distributions will be payable to Holders as
they appear on the books and records of the Trust on the first record date
preceding the end of the Extension Period. Upon the termination of any Extension
Period and the payment of all amounts then due, the Debenture Issuer may
commence a new Extension Period, subject to the above requirements.

            Subject to the Sponsor obtaining any prior regulatory approval then
required and to certain other conditions set forth in the Declaration and the
Indenture, the Property Trustee may, at the direction of the Sponsor, at any
time terminate the Trust and, after satisfaction of any liabilities to creditors
of the Trust in accordance with applicable law,

liquidation of the Trust or, simultaneous with any redemption of the Debentures,

            The Capital Securities shall be redeemable as provided in the
Declaration.

to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert. The

            The Guarantor hereby waives notice of acceptance of this Series B
Capital Securities Guarantee and of any liability to which it applies or may

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

SECTION 5.3 Obligations Not Affected

covenant, term or condition relating to the Series B Capital Securities to be
performed or observed by the Issuer;



                                       14
<PAGE>   18
            (b) the extension of time for the payment by the Issuer of all or
any portion of the Distributions, Redemption Price, Liquidation Distribution or
any other sums payable under the terms of the Series B Capital Securities or the
extension of time for the performance of any other obligation under, arising out
of, or in connection with, the Series B Capital Securities (other than an
extension of time for payment of Distributions, Redemption Price, Liquidation
Distribution or other sum payable that results from the extension of any
interest payment period on the Debentures permitted by the Indenture);

            (c) any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Series B Capital
Securities, or any action on the part of the Issuer granting indulgence or
extension of any kind;

            (d) 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 Issuer or any of the assets of
the Issuer;

            (e) any invalidity of, or defect or deficiency in, the Series B
Capital Securities;

            (f) the settlement or compromise of any obligation guaranteed hereby
or hereby incurred;

            (g) the consummation of the Exchange Offer; or

            (h) any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor, it being
the intent of this Section 5.3 that the obligations of the Guarantor with
respect to the Guarantee Payments shall be absolute and unconditional under any
and all circumstances.

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

SECTION 5.4 Rights of Holders

            (a) The Holders of a Majority in liquidation amount of the Series B
Capital Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Capital Securities
Guarantee Trustee in respect of this Series B Capital Securities Guarantee or
exercising any trust or power conferred upon the Capital Securities Guarantee
Trustee under this Series B Capital Securities Guarantee, provided, however,
that, subject to Section 3.1, the Capital Securities Guarantee Trustee shall
have the right to decline to follow any such direction if the Capital Securities
Guarantee Trustee shall determine that the action so directed would be unjustly
prejudicial


                                       15
<PAGE>   19
to the holders not taking part in such direction or if the Capital Securities
Guarantee Trustee being advised by counsel determines that the action or
proceeding so directed may not lawfully be taken or if the Capital Securities
Guarantee Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees and/or Responsible
Officers shall determine that the action or proceedings so directed would
involve the Capital Securities Guarantee Trustee in personal liability.

            (b) If the Capital Securities Guarantee Trustee fails to enforce
such Series B Capital Securities Guarantee, any Holder may institute a legal
proceeding directly against the Guarantor to enforce the Capital Securities
Guarantee Trustee's rights under this Series B Capital Securities Guarantee,
without first instituting a legal proceeding against the Issuer, the Capital
Securities Guarantee Trustee or any other person or entity. The Guarantor waives
any right or remedy to require that any action be brought first against the
Issuer or any other person or entity before proceeding directly against the
Guarantor.

SECTION 5.5 Guarantee of Payment

            This Series B Capital Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6 Subrogation

            The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this Series B Capital Securities Guarantee; provided, however,
that the Guarantor shall not (except to the extent required by mandatory
provisions of law) be entitled to enforce or exercise any right that it may
acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Series B Capital
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Series B Capital Securities Guarantee. 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.

            The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Series B
Capital Securities, and that the Guarantor shall be liable as principal and as
debtor hereunder to make Guarantee Payments pursuant to the terms of this Series
B Capital Securities Guarantee notwithstanding the occurrence of any event
referred to in subsections (a) through (h), inclusive, of Section 5.3 hereof.

respect of which the Guarantor shall not have taken reasonable steps to cure,
(iii) if such Debentures are held by the Property Trustee, the Guarantor shall
be in default with respect to its payment of any obligations under this Series B

          2.   REGISTRATION UNDER THE SECURITIES ACT.

          (a)  EXCHANGE OFFER.   To the extent not prohibited by any applicable 
law or applicable interpretation of the staff of the SEC, the Company and the
Trust shall, for the benefit of the Holders, at the Company's cost, use its
reasonable best efforts to (i) cause to be filed with the SEC within 150 days
after the Issue Date an Exchange Offer Registration Statement on an appropriate
form under the Securities Act covering the Exchange Offer and (ii) cause such
Exchange Offer Registration Statement to be declared effective under the
Securities Act by the SEC not later than the date which is 180 days after the
Issue Date. In addition, in the event that the Company has filed a Shelf
Registration Statement in accordance with the provisions of Section 2(b) in lieu
of conducting an Exchange Offer in accordance with the foregoing sentence, the
Company may, if permitted in accordance with then applicable regulations and the
then current interpretations of the staff of the Commission, elect to conduct an
Exchange Offer in accordance with the terms set forth herein, other than with
respect to the specific timing requirements set forth in the foregoing sentence.
In the event the Company conducts such an Exchange Offer subsequent to the
filing and effectiveness of a Shelf Registration Statement, the Company's
obligations to maintain such a Shelf Registration shall terminate. Upon the
effectiveness of the Exchange Offer Registration Statement, the Company and the
Trust shall promptly commence the Exchange Offer, it being the objective of such
Exchange Offer to enable each Holder eligible and electing to exchange
Registrable Securities for a like principal amount of Exchange Debentures or a
like liquidation amount of Exchange Capital Securities, together with the
Exchange Guarantee, as applicable (assuming that such Holder is not an affiliate
of the Company within the meaning of Rule 405 under the Securities Act and is
not a broker-dealer tendering Registrable Securities acquired directly from the
Company for its own account, acquires the Exchange Securities in the ordinary
course of such Holder's business and has no arrangements or understandings with
any Person to participate in the Exchange Offer for the purpose of distributing
the Exchange Securities) to transfer such Exchange Securities from and after
their receipt without any limitations or restrictions under the Securities Act
and under state securities or blue sky laws.

          In connection with the Exchange Offer, the Company and the Trust
shall:

     (i)    mail to each Holder a copy of the Prospectus forming part of the
Exchange Offer Registration Statement, together with an appropriate letter of
transmittal and related documents;


     (ii)   keep the Exchange Offer open for acceptance for a period of not less
than 30 days after the date notice thereof is mailed to


                                        7

<PAGE>   8



the Holders (or longer if required by applicable law) (such period referred to
herein as the "EXCHANGE PERIOD");


     (iii)  utilize the services of the Depositary for the Exchange Offer;

     (iv)   permit Holders to withdraw tendered Securities at any time prior to
the close of business, New York time, on the last Business Day of the Exchange
Period, by sending to the institution specified in the notice, a telegram,
telex, facsimile transmission or letter setting forth the name of such Holder,
the principal amount of Securities delivered for exchange, and a statement that
such Holder is withdrawing his election to have such Securities exchanged;

     (v)    notify each Holder that any Security not tendered by such Holder in
the Exchange Offer will remain outstanding and continue to accrue interest or
accumulate distributions, as the case may be, but will not retain any rights
under this Agreement; and

     (vi)   otherwise comply in all material respects with all applicable laws
relating to the Exchange Offer.

          As soon as practicable after the close of the Exchange Offer, the
Company and the Trust, as the case requires, shall:

     (i)    accept for exchange all Securities or portions thereof tendered and
not validly withdrawn pursuant to the Exchange Offer;

     (ii)   deliver, or cause to be delivered, to the applicable Trustee for
cancellation all Securities or portions thereof so accepted for exchange by the
Company; and

     (iii)  issue, and cause the applicable Trustee under the Indenture, the
Declaration or the Guarantee, as applicable, to promptly authenticate and
deliver to each Holder, new Exchange Securities equal in principal amount to the
principal amount of the Subordinated Debentures or equal in liquidation amount
to the liquidation amount to the Capital Securities (together with the guarantee
thereof) as are surrendered by such Holder.

          Distributions on each Exchange Capital Security and interest on each
Exchange Debenture issued pursuant to the Registered Exchange Offer will accrue
from the last date on which a Distribution or interest was paid on the Capital
Security or the Subordinated Debenture surrendered in exchange therefore or, if
no Distribution or interest has been paid on such Capital Security or
Subordinated Debenture, from the Issue Date. To the extent not prohibited by any
law or applicable interpretations of the staff of the SEC, the Company and the
Trust shall use their reasonable best efforts to complete the Exchange Offer as
provided above, and shall

                                        8

<PAGE>   9



comply with the applicable requirements of the Securities Act, the Exchange Act
and other applicable laws in connection with the Exchange Offer. The Exchange
Offer shall not be subject to any conditions, other than that the Exchange Offer
does not violate applicable law or any applicable interpretation of the staff of
the SEC. Each Holder of Registrable Securities who wishes to exchange such
Registrable Securities for Exchange Securities in the Exchange Offer will be
required to make certain customary representations in connection therewith,
including, in the case of any Holder of Capital Securities, representations that
(i) it is not an affiliate of the Trust or the Company, (ii) the Exchange
Securities to be received by it were acquired in the ordinary course of its
business and (iii) at the time of the Exchange Offer, it has no arrangement with
any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Capital Securities. Participating Broker-Dealers
and others who cannot make such representations will not acquire freely-tradable
Exchange Capital Securities. The Company and the Trust shall inform the Initial
Purchasers, after consultation with the Trustee, of the names and addresses of
the Holders to whom the Exchange Offer is made, and the Initial Purchasers shall
have the right to contact such Holders and otherwise facilitate the tender of
Registrable Securities in the Exchange Offer.

          Upon consummation of the Exchange Offer in accordance with this
Section 2(a), the Company and the Trust shall have no further obligation to
register the Registrable Securities.

          (b)  SHELF REGISTRATION.   In the event that (i) the Company, the 
Trust or the Majority Holders reasonably determine, after conferring with
counsel (which may be in-house counsel), that the Exchange Offer Registration
provided in Section 2(a) above is not available under applicable laws and
regulations and currently prevailing interpretations of the staff of the SEC or
(ii) the Exchange Offer Registration Statement is not declared effective within
180 days of the Issue Date (any of the events specified in (i)-(ii) being a
"SHELF REGISTRATION EVENT" and the date of occurrence thereof, the "SHELF
REGISTRATION EVENT DATE"), the Company and the Trust shall, at their cost, use
their reasonable best efforts to cause to be filed as promptly as practicable
after such Shelf Registration Event Date, as the case may be, and within 45 days
after such Shelf Registration Event Date (provided that in no event shall such
date be earlier than 75 days after the Issue Date), a Shelf Registration
Statement providing for the sale by the Holders of all of the Registrable
Securities, and shall use its reasonable best efforts to have such Shelf
Registration Statement declared effective by the SEC as soon as practicable. No
Holder of Registrable Securities shall be entitled to include any of its
Registrable Securities in any Shelf Registration pursuant to this Agreement
unless and until such Holder agrees in writing to be bound by all of the
provisions of this Agreement applicable to such Holder and furnishes to the
Company and the Trust in writing,


                                        9

<PAGE>   10



within 15 days after receipt of a request therefor, such information as the
Company and the Trust may, after conferring with counsel with regard to
information relating to Holders that would be required by the SEC to be included
in such Shelf Registration Statement or Prospectus included therein, reasonably
request for inclusion in any Shelf Registration Statement or Prospectus included
therein. Each Holder as to which any Shelf Registration is being effected agrees
to furnish to the Company and the Trust all information with respect to such
Holder necessary to make the information previously furnished to the Company by
such Holder not materially misleading.

          The Company and the Trust agree to use their reasonable best efforts
to keep the Shelf Registration Statement continuously effective for the Rule
144(k) Period (subject to extension pursuant to the last paragraph of Section 3
hereof) or for such shorter period which will terminate when all of the
Registrable Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement or cease to be outstanding
(the "EFFECTIVENESS PERIOD"). The Company and the Trust shall not permit any
securities other than Registrable Securities to be included in the Shelf
Registration. The Company and the Trust will, in the event a Shelf Registration
Statement is declared effective, provide to each Holder a reasonable number of
copies of the Prospectus which is a part of the Shelf Registration Statement and
notify each such Holder when the Shelf Registration has become effective. The
Company and the Trust further agree, if necessary, to supplement or amend the
Shelf Registration Statement, if required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registrations, and the Company and the Trust
agree to furnish to the Holders of Registrable Securities copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

          (c)  EXPENSES.   The Company shall pay all Registration Expenses in
connection with the registration pursuant to Section 2(a) or 2(b) hereof and
will reimburse the Initial Purchasers for the reasonable fees and disbursements
of Brown & Wood LLP, counsel for the Initial Purchasers, incurred in connection
with the Exchange Offer, provided that, except with respect to such fees of
Brown & Wood LLP, each Holder shall pay all expenses of its own counsel,
underwriting discounts and commissions and transfer taxes, if any, relating to
the sale or disposition of such Holder's Regis- trable Securities pursuant to
the Shelf Registration Statement.

          (d)  EFFECTIVE REGISTRATION STATEMENT.   An Exchange Offer 
Registration Statement pursuant to Section 2(a) hereof or a Shelf Registration
Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC; PROVIDED, HOWEVER,
that if, after it has been


                                       10

<PAGE>   11



declared effective, the offering of Registrable Securities pursuant to a Shelf
Registration Statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
Registration Statement will be deemed not to have been effective during the
period of such interference, until the offering of Registrable Securities
pursuant to such Registration Statement may legally resume. The Company and the
Trust will be deemed not to have used their reasonable best efforts to cause the
Exchange Offer Registration Statement or the Shelf Registration Statement, as
the case may be, to become, or to remain, effective during the requisite period
if either of them voluntarily take any action that would result in any such
Registration Statement not being declared effective or in the Holders of
Registrable Securities covered thereby not being able to exchange or offer and
sell such Registrable Securities during that period unless such action is
required by applicable laws and regulations or currently prevailing
interpretations of the staff of the SEC.

          (e)  LIQUIDATED DAMAGES.   In the event that:

     (i)    neither the Exchange Offer Registration Statement nor a Shelf
Registration Statement is filed with the SEC on or prior to the 150th day after
the Issue Date, then commencing on the day after the applicable required filing
date, additional interest shall accrue on the principal amount of the
Subordinated Debentures, and additional Distributions shall accumulate on the
liquidation amount of the Capital Securities, each at a rate of 0.25% per annum;
or

     (ii)   neither the Exchange Offer Registration Statement nor a Shelf
Registration Statement is declared effective by the SEC on or prior to the 30th
day after the applicable required filing date, then, commencing on the 31st day
after the applicable required filing date, additional interest shall accrue on
the principal amount of the Subordinated Debentures, and additional
distributions shall accumulate on the liquidation amount of the Capital
Securities, each at a rate of 0.25% per annum; or

     (iii)  (A)  the Trust has not exchanged Exchange Capital Securities for all
Capital Securities or the Company has not exchanged Exchange Guarantees or
Exchange Subordinated Debentures for all Guarantees or Subordinated Debentures
validly tendered, in accordance with the terms of the Exchange Offer on or prior
to the 30th day after the date on which the Exchange Offer Registration
Statement was declared effective or (B) if applicable, the Shelf Registration
Statement has been declared effective and such Shelf Registration Statement
ceases to be effective at any time prior to the expiration of the Rule 144(k)
Period (other than (a) after such time as all Capital Securities have been
disposed of thereunder or otherwise cease to be Registrable Securities, (b) if
the Company effects an Exchange Offer and is no longer obligated to maintain the
effectiveness of the Shelf Registration Statement or (c) an


                                       11

<PAGE>   12



Exchange Offer has been consummated), then additional interest shall accrue on
the principal amount of Subordinated Debentures, and additional distributions
shall accumulate on the liquidation amount of the Capital Securities, each at a
rate of 0.25% per annum commencing on (x) the 31st day after such effective
date, in the case of (A) above, or (y) the day such Shelf Registration Statement
ceases to be effective in the case of (B) above;

provided, however, that neither the additional interest rate on the Subordinated
Debentures, nor the additional distribution rate on the liquidation amount of
the Capital Securities, may exceed in the aggregate 0.25% per annum; provided,
further, however, that (1) upon the filing of the Exchange Offer Registration
Statement or a Shelf Registration Statement (in the case of clause (i) above),
(2) upon the effectiveness of the Exchange Offer Registration Statement or a
Shelf Registration Statement (in the case of clause (ii) above), or (3) upon the
exchange of Exchange Capital Securities, Exchange Guarantees and Exchange
Subordinated Debentures for all Capital Securities, Guarantees and Subordinated
Debentures tendered (in the case of clause (iii)(A) above), or upon the
effectiveness of the Shelf Registration Statement which had ceased to remain
effective (in the case of clause (iii)(B) above), additional interest on the
Subordinated Debentures, and additional distributions on the liquidation amount
of the Capital Securities as a result of such clause (or the relevant subclause
thereof), as the case may be, shall cease to accrue or accumulate, as the case
may be.

     Any amounts of additional interest and additional Distributions due
pursuant to Section 2(e)(i), (ii) or (iii) above ("Liquidated Damages") will be
payable in cash on the next succeeding February 1 or August 1, as the case may
be, to holders on the relevant record dates for the payment of interest and
Distributions pursuant to the Indenture and the Declaration, respectively.

          (f)  SPECIFIC ENFORCEMENT.   Without limiting the remedies available 
to the Holders, the Company and the Trust acknowledge that any failure by the
Company or the Trust to comply with its obligations under Section 2(a) and
Section 2(b) hereof may result in material irreparable injury to the Holders for
which there is no adequate remedy at law, that it would not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, any Holder may obtain such relief as may be required to specifically
enforce the Company's and the Trust's obligations under Section 2(a) and Section
2(b) hereof.

          3.   REGISTRATION PROCEDURES.   In connection with the obligations of
the Company and the Trust with respect to the Regis- tration Statements pursuant

PROVIDED, HOWEVER, that if (1) such filing is pursuant to Section 2(b), or (2) a
Prospectus contained in an Exchange Offer Registration Statement filed pursuant
to Section 2(a) is required to be delivered under the Securities Act by any
Participating Broker-Dealer who seeks to sell Exchange Securities, before filing
any Registration Statement or Prospectus or any amendments or supplements
thereto, the Company and the Trust shall furnish to and afford the Holders of
the Registrable Securities and each such Participating Broker-Dealer, as the
case may be, covered by such Registration Statement, their counsel and the
managing underwriters, if any, a reasonable opportunity to review copies of the
Registration Statement and Prospectus proposed to be filed. The Company and the
Trust shall not file any Registration Statement or Prospectus or any amendments
or supplements thereto in respect of which the Holders must be afforded an

Effectiveness Period or the Applicable Period, as the case may be, in accordance
with the intended method or methods of distribution by the selling Holders
thereof described in this Agreement (including sales by any Participating
Broker-Dealer);



                                       13

<PAGE>   14



          (c)  in the case of a Shelf Registration, (i) notify each Holder of
Registrable Securities included in the Shelf Registration Statement, at least
three Business Days prior to filing, that a Shelf Registration Statement with
respect to the Registrable Securities is being filed and advising such Holder
that the distribution of Registrable Securities will be made in accordance with
the method selected by the Majority Holders; and (ii) furnish to each Holder of

pursuant to a subpoena or other order from a court of competent jurisdiction or

inspections shall be deemed confidential and shall not be used by it as the
basis for any market transactions in the securities of the Trust or the Company

Securities and each such Participating Broker-Dealer will be required to further
agree in writing that it will, upon learning that disclosure of such Records is
sought in a court of competent jurisdiction or in connection with any action,
suit or proceeding, give notice to the Company and allow the Company at its
expense to undertake appropriate action to prevent disclosure of the Records
deemed confidential;

end of any 12-month period if such period is a fiscal year) (i) commencing at
the end of any fiscal quarter in which Registrable Securities are sold to
underwriters in a firm commitment or best efforts underwritten offering and (ii)

for the benefit of all Holders of Registrable Securities participating in the
Exchange Offer to the effect that (i) the Company and the Trust, as the case
requires, has duly authorized, executed and delivered the Exchange Securities
and (ii) each of the Exchange Securities constitutes a legal, valid and binding
obligation of the Company or the Trust, as the case requires, enforceable
against the Company or the Trust, as the case requires, in accordance with its
respective terms (in each case, with customary exceptions);

          (p)  if an Exchange Offer is to be consummated, upon delivery of the
Registrable Securities by Holders to the Company or the Trust, as applicable (or
to such other Person as directed by the Company or the Trust, respectively), in
exchange for the Exchange Securities, the Company or the Trust, as applicable,
shall mark, or cause to be marked, on such Registrable Securities delivered by
such Holders that such Registrable Securities are being cancelled in exchange
for the Exchange Securities;

          (q)  cooperate with each seller of Registrable Securities covered by
any Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Securities and their respective counsel in

appropriate representative of the Participating Broker-Dealers who constitute a
Majority Holder, if any, and which shall contain a summary statement of the

will be the beneficial owner (as defined in Rule 13d-3 under the Exchange Act)
of Exchange Securities to be received by such broker-dealer in the Exchange

Exchange Securities, (ii) furnish to each Participating Broker-Dealer who has
delivered to the Company the notice referred to in Section 3(e), without charge,
as many copies of each Prospectus included in the Exchange Offer Registration

thereto, as such Participating Broker-Dealer may reasonably request (each of the
Company and the Trust hereby consents to the use of the Prospectus forming part
of the Exchange Offer Registration Statement or any amendment or supplement
thereto by any Person subject to the prospectus delivery requirements of the
Securities Act, including all Participating Broker-Dealers, in connection with
the sale or transfer of the Exchange Securities covered by the Prospectus or any
amendment or supplement thereto), (iii) use its reasonable best efforts to keep
the Exchange Offer Registration Statement effective and to amend and supplement
the Prospectus contained therein in order to permit such Prospectus to be
lawfully delivered by all Persons subject to the prospectus delivery
requirements of the Securities Act for such period of time as such Persons must
comply with such requirements under the Securities Act and applicable rules and
regulations in order to resell the Exchange Securities; PROVIDED, HOWEVER, that
such period shall not be required to exceed 90 days (or such longer period if
extended pursuant to the last sentence of Section 3 hereof) (the "APPLICABLE
PERIOD"), and (iv) include in the transmittal letter or similar documentation to
be executed by an exchange offeree in order to participate in the Exchange Offer
(x) the following provision:

          "If the exchange offeree is a broker-dealer holding Registrable
          Securities acquired for its own account as a result of market-making

          meeting the requirements of the Securities Act in connection with any
          resale of Exchange Securities received in respect of such Registrable
          Securities pursuant to the Exchange Offer";

and (y) a statement to the effect that by a broker-dealer making the
acknowledgment described in clause (x) and by delivering a Prospectus in
connection with the exchange of Registrable Securities, the broker-dealer will
not be deemed to admit that it is an underwriter within the meaning of the
Securities Act; and

          (B) in the case of any Exchange Offer Registration Statement, the
     Company and the Trust agree to deliver to an appropriate representative of
     the Participating Broker-Dealers who constitute a Majority Holder, if any,
     if requested by any such representative of such Participating
     Broker-Dealers, on behalf of such Participating Broker-Dealers upon
     consummation of the Exchange Offer (i) an opinion of counsel in form and
     substance reasonably satisfactory to such representative of such
     Participating Broker-Dealers, covering the matters customarily covered in
     opinions requested in connection with Exchange Offer Registration
     Statements and such other matters as may be reasonably requested (it being
     agreed that the matters to be covered by such opinion may be subject to
     customary qualifications and exceptions), (ii) an officers' certificate
     containing certifications substantially similar to those set forth in
     Section 5(g) of the Purchase Agreement and such additional certifications
     as are customarily delivered in a public offering of debt securities and

     Statement, a comfort letter, in each case, in customary form if permitted
     by Statement on Auditing Standards No. 72.

          The Company or the Trust may require each seller of Registrable
Securities as to which any registration is being effected to furnish to the
Company or the Trust, as applicable, such information regarding such seller as
may be required by the staff of the SEC to be included in a Registration
Statement. The Company or the Trust may exclude from such registration the
Registrable Securities of any seller who fails to furnish such information
within a reasonable time after receiving such request. The Company shall have no
obligation to register under the Securities Act the Registrable Securities of a
seller who so fails to furnish such information.

          In the case of (1) a Shelf Registration Statement or (2) Participating
Broker-Dealers who have notified the Company and the Trust that they will be
utilizing the Prospectus contained in the Exchange Offer Registration Statement
as provided in Section 3(s) hereof, are seeking to sell Exchange Securities and
are


                                       21

<PAGE>   22



required to deliver Prospectuses each Holder agrees that, upon receipt of any
notice from the Company or the Trust of the happening of any event of the kind
described in Section 3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, such
Holder will forthwith discontinue disposition of Registrable Securities pursuant
to a Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof or until
it is advised in writing (the "ADVICE") by the Company and the Trust that the
use of the applicable Prospectus may be resumed, and, if so directed by the
Company and the Trust, such Holder will deliver to the Company or the Trust (at
the Company's or the Trust's expense, as the case requires) all copies in such
Holder's possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Securities or Exchange
Securities, as the case may be, current at the time of receipt of such notice.
If the Company or the Trust shall give any such notice to suspend the
disposition of Registrable Securities or Exchange Securities, as the case may
be, pursuant to a Registration Statement, the Company and the Trust shall use
their reasonable best efforts to file and have declared effective (if an
amendment) as soon as practicable an amendment or supplement to the Registration
Statement and shall extend the period during which such Registration Statement
shall be maintained effective pursuant to this Agreement by the number of days
in the period from and including the date of the giving of such notice to and
including the date when the Company and the Trust shall have made available to
the Holders (x) copies of the supplemented or amended Prospectus necessary to
resume such dispositions or (y) the Advice.

          4.   INDEMNIFICATION AND CONTRIBUTION.   (a) In connection with any
Registration Statement, the Company and the Trust shall, jointly and severally,
indemnify and hold harmless each Initial Purchaser, each Holder, each
underwriter who participates in an offering of the Registrable Securities, each
Participating Broker-Dealer, each Person, if any, who controls any of such
parties within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act and each of their respective directors, officers, employees and
agents, as follows:

          (i)   from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, arising out of any
     untrue statement or alleged untrue statement of a material fact contained
     in any Registration Statement (or any amendment thereto), covering
     Registrable Securities or Exchange Securities, including all documents
     incorporated therein by reference, or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     Prospectus (or any amendment or supplement thereto) or the omission


                                       22

<PAGE>   23



     or alleged omission therefrom of a material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading;

          (ii)   from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, to the extent of the
     aggregate amount paid in settlement of any litigation, or any investigation
     or proceeding by any court or governmental agency or body, commenced or
     threatened, or of any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission, if such
     settlement is effected with the prior written consent of the Company; and

          (iii)   from and against any and all expenses whatsoever reasonably
     incurred in investigating, preparing or defending against any litigation,
     or any investigation or proceeding by any court or governmental agency or
     body, commenced or threatened, or any claim whatsoever based upon any such
     untrue statement or omission, or any such alleged untrue statement or
     omission, to the extent that any such expense is not paid under
     subparagraph (i) or (ii) of this Section 4(b);

PROVIDED, HOWEVER, that (i) this indemnity does not apply to any loss,
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished in writing to the
Company or the Trust by such Holder, such Participating Broker-Dealer or any
underwriter with respect to such Holder, Participating Broker-Dealer or any
underwriter, as the case may be, expressly for use in the Registration Statement
(or any amendment thereto) or any Prospectus (or any amendment or supplement
thereto) and (ii) the Company and the Trust shall not be liable to any such
Holder, Participating Broker- Dealer, any underwriter or controlling person,
with respect to any untrue statement or alleged untrue statement or omission or
alleged omission in any preliminary Prospectus to the extent that any such loss,
liability, claim, damage or expense of any Holder, Participating Broker-Dealer,
any underwriter or controlling person results from the fact that such Holder,
any underwriter or Participating Broker-Dealer sold Securities to a person to
whom there was not sent or given, at or prior to the written confirmation of
such sale, a copy of the final Prospectus as then amended or supplemented if the
Company had previously furnished copies thereof to such Holder, underwriter or
Participating Broker-Dealer and the loss, liability, claim, damage or expense of
such Holder, underwriter, Participating Broker-Dealer or controlling person
results from an untrue statement or omission of a material fact contained in the
preliminary Prospectus which was corrected in the final Prospectus. Any amounts
advanced by the Company or the Trust to an indemnified party pursuant to this
Section 4 as a result of such losses shall be returned to the Company or the
Trust if it shall be


                                       23

<PAGE>   24



finally determined by such a court in a judgment not subject to appeal or final
review that such indemnified party was not entitled to indemnification by the
Company or the Trust.

          (b)  Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Trust, any underwriter and the other selling
Holders and each of their respective directors, officers (including each officer
of the Company and the Trust who signed the Registration Statement), employees
and agents and each Person, if any, who controls the Company, the Trust, any
underwriter or any other selling Holder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
loss, liability, claim, damage and expense whatsoever described in the indemnity
contained in Section 4(a) hereof, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto) or any Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company or the Trust by such selling Holder with
respect to such Holder expressly for use in the Registration Statement (or any
amendment thereto), or any such Prospectus (or any amendment or supplement
thereto); PROVIDED, HOWEVER, that, in the case of Shelf Registration Statement,
no such Holder shall be liable for any claims hereunder in excess of the amount
of net proceeds received by such Holder from the sale of Registrable Securities
pursuant to such Shelf Registration Statement.

          (c)  Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party, but failure to so notify an indemnifying party
shall not relieve such indemnifying party from any liability which it may have
under this Section 4, except to the extent that it is materially prejudiced by
such failure. An indemnifying party may participate at its own expense in the
defense of any such action, or, if it so elects within a reasonable time after
receipt of such notice, assume the defense of any suit brought to enforce any
such claim; but if it so elects to assume the defense, such defense shall be
conducted by counsel chosen by it and approved by the indemnified party or
parties, which approval shall not be unreasonably withheld. In the event that an
indemnifying party elects to assume the defense of any such suit and retain such
counsel, the indemnified party or parties shall bear the fees and expenses of
any additional counsel thereafter retained by such indemnified party or parties;
provided, however, that the indemnified party or parties shall have the right to
employ counsel (in addition to local counsel) to represent the indemnified party
or parties who may be subject to liability arising out of any action in respect
of which indemnity may be sought against the indemnifying party if, in the
reasonable judgment of counsel for the indemnified party or parties, there may


                                       24

<PAGE>   25



be a conflict of interest such that multiple representation would violate the
Code of Professional Responsibility or like governing rules, in which event the
fees and expenses of appropriate separate counsel shall be borne by the
indemnifying party. In no event shall the indemnifying parties be liable for the
fees and expenses of more than one counsel (in addition to local counsel),
separate from its own counsel, for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances. No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 4 (whether or not the indemnified parties are actual or potential
parties thereto), unless such settlement, compromise or consent (i) includes an
unconditional written release in form and substance satisfactory to the
indemnified parties of each indemnified party from all liability arising out of
such litigation, investigation, proceeding or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party.

          (d)  In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 4 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company, the Trust, and
the Holders shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Company, the Trust, and the Holders, as incurred; PROVIDED that
no Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any Person that
was not guilty of such fraudulent misrepresentation. As between the Company, the
Trust, and the Holders, such parties shall contribute to such aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by such
indemnity agreement in such proportion as shall be appropriate to reflect the
relative fault of the Company and Trust, on the one hand, and the Holders, on
the other hand, with respect to the statements or omissions which resulted in
such loss, liability, claim, damage or expense, or action in respect thereof, as
well as any other relevant equitable considerations. The relative fault of the
Company and the Trust, on the one hand, and of the Holders, on the other hand,
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company or the
Trust, on the one hand, or by or on behalf of the Holders, on the other, and the
parties' relative intent, knowledge, access to information and opportunity to
correct


                                       25

or prevent such statement or omission. The Company, the Trust and the Holders of
the Registrable Securities agree that it would not be just and equitable if
contribution pursuant to this Section 4 were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the relevant equitable considerations. For purposes of this Section 4, each
affiliate of a Holder, and each director, officer, employee, agent and Person,
if any, who controls a Holder or such affiliate within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as such Holder, and each director of each of the Company
or the Trust, each officer of each of the Company or the Trust who signed the
Registration Statement, and each Person, if any, who controls each of the
Company and the Trust within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act shall have the same rights to contribution as
each of the Company or the Trust.

          5.   PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.   No Holder may
participate in any underwritten registration hereunder unless such Holder (a)
agrees to sell such Holder's Registrable Securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorney, indemnities, underwriting agreements, lock-up letters and
other documents reasonably required under the terms of such underwriting
arrangements.

          6.   SELECTION OF UNDERWRITERS.   The Holders of Registrable 
Securities covered by the Shelf Registration Statement who desire to do so may
sell the securities covered by such Shelf Registration in an underwritten
offering. In any such underwritten offering, the underwriter or underwriters and
manager or managers that will administer the offering will be selected by the
Holders of a majority in aggregate principal amount of the Registrable
Securities included in such offering; provided, however, that such underwriters
and managers must be of national reputation and reasonably satisfactory to the
Company and the Trust.

          7.   MISCELLANEOUS.

          (a)  RULE 144 AND RULE 144A.   For so long as the Company or the Trust
is subject to the reporting requirements of Section 13 or 15 of the Exchange Act
and any Registrable Securities remain outstanding, each of the Company and the
Trust, as the case may be, will use its reasonable best efforts to file the
reports required to be filed by it under the Securities Act and Section 13(a) or
15(d) of the Exchange Act and the rules and regulations adopted by the SEC
thereunder. Each of the Company and the Trust also agree that if it ceases to be
so required to file such reports, it will, upon the request of any Holder of
Registrable Securities (a) make publicly available such information as is
necessary to permit sales of its securities pursuant to Rule 144 under the
Securities Act,


                                       26

<PAGE>   27



(b) deliver such information to a prospective purchaser as is necessary to
permit sales of its securities pursuant to Rule 144A under the Securities Act,
and (c) take such further action that is reasonable in the circumstances, in
each case, to the extent required from time to time to enable such Holder to
sell its Registrable Securities without registration under the Securities Act
within the limitation of the exemptions provided by (i) Rule 144 under the
Securities Act, as such rule may be amended from time to time, (ii) Rule 144A
under the Securities Act, as such rule may be amended from time to time, or
(iii) any similar rules or regulations hereafter adopted by the SEC. Upon the
request of any Holder of Registrable Securities, the Company and the Trusts will
deliver to such Holder a written statement as to whether it has complied with
such requirements.

          (b)  NO INCONSISTENT AGREEMENTS.   The Company or the Trust has not
entered into nor will the Company or the Trust on or after the date of this
Agreement enter into any agreement which is inconsistent with the rights granted
to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof. The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Company's or the Trust's other issued and
outstanding securities under any such agreements.

          (c)  AMENDMENTS AND WAIVERS.   The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company and the Trust has obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or departure; PROVIDED no amendment, modification or
supplement or waiver or consent to the departure with respect to the provisions
of Section 4 hereof which materially adversely affects the rights of any Holder
of Registrable Securities shall be effective as against such Holder of
Registrable Securities unless consented to in writing by such Holder of
Registrable Securities. Notwithstanding the foregoing sentence, (i) this
Agreement may be amended, without the consent of any Holder of Registrable
Securities, by written agreement signed by the Company, the Trust and KBW, to
cure any ambiguity, correct or supplement any provision of this Agreement that
may be inconsistent with any other provision of this Agreement or to make any
other provisions with respect to matters or questions arising under this
Agreement which shall not be inconsistent with other provisions of this
Agreement, (ii) this Agreement may be amended, modified or supplemented, and
waivers and consents to departures from the provisions hereof may be given, by
written agreement signed by the Company, the Trust and KBW to the extent that
any such amendment, modification, supplement, waiver or consent is, in their
reasonable judgment, necessary or appropriate to comply with


                                       27

<PAGE>   28



applicable law (including any interpretation of the Staff of the SEC) or any
change therein and (iii) to the extent any provision of this Agreement relates
to the Initial Purchasers, such provision may be amended, modified or
supplemented, and waivers or consents to departures from such provisions may be
given, by written agreement signed by KBW, the Company and the Trust.

          (d)  NOTICES.   All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company or the Trust by means of a notice given in accordance with the
provisions of this Section 7(d), which address initially is, with respect to the
Initial Purchasers, the address set forth in the Purchase Agreement; and (ii) if
to the Company or the Trust, initially at the Company's address set forth in the
Purchase Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 7(d).

          All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied; and on
the next Business Day, if timely delivered to an air courier guaranteeing
overnight delivery.

          Copies of all such notices, demands, or other communications shall be
concurrently delivered by the Person giving the same to the Trustee, at the
address specified in the Indenture.

          (e)  SUCCESSORS AND ASSIGNS.   This Agreement shall inure to the 
benefit of and be binding upon the successors, assigns and transferees of the
Initial Purchasers, including, without limitation and without the need for an
express assignment, subsequent Holders; PROVIDED, HOWEVER, that nothing herein
shall be deemed to permit any assignment, transfer or other disposition of
Registrable Securities in violation of the terms of the Purchase Agreement or
the Indenture. If any transferee of any Holder shall acquire Registrable
Securities, in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities, such Person
shall be conclusively deemed to have agreed to be bound by and to perform all of
the terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof.

          (f)  THIRD PARTY BENEFICIARY.   Each of the Initial Purchasers shall 
be a third party beneficiary of the agreements made hereunder between the
Company and the Trust, on the one hand, and the Holders, on the other hand, and
shall have the right to


                                       28

<PAGE>   29



enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

          (g)  COUNTERPARTS.   This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

          (h)  HEADINGS.   The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (i)  GOVERNING LAW.   THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN MADE
IN THE STATE OF NEW YORK. THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT, AND
THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY
PROVISIONS RELATING TO CONFLICTS OF LAWS. EACH OF THE PARTIES HERETO AGREES TO
SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION
OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

          (j)  SEVERABILITY.   In the event that any one or more of the 
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

          (k)  SECURITIES HELD BY THE COMPANY, THE TRUST OR ITS AFFILIATES.
Whenever the consent or approval of Holders of a specified percentage of
Registrable Securities is required hereunder, Registrable Securities held by the
Company, the Trust or its affiliates (as such term is defined in Rule 405 under
the Securities Act) shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage.

         For purposes of computing the consolidated ratio of earnings to fixed
charges, "earnings" represent income (loss) before extraordinary items and
cumulative effect of a change in accounting principle plus applicable income
taxes and fixed charges. "Fixed charges" include gross interest expense
(excluding interest on deposits) and the proportion deemed representative of the
interest factor of rent expense. For the year ended December 31, 1992, earnings
were insufficient to cover fixed charges by $5.4 million.

         For purposes of computing the consolidated ratio of earnings to fixed
charges, "earnings" represent income (loss) before extraordinary items and
cumulative effect of a change in accounting principle plus applicable income
taxes and fixed charges. "Fixed charges" include gross interest expense
(including interest on deposits) and the proportion deemed representative of the
interest factor of rent expense. For the year ended December 31, 1992, earnings
were insufficient to cover fixed charges by $5.4 million.

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER


      1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES; GUARANTEED DELIVERY
PROCEDURES. This Letter of Transmittal is to be completed either if (a) tenders
are to be made pursuant to the procedures for tender by book-entry transfer set
forth under "The Exchange Offer--Procedures for Tendering Old Capital
Securities" in the Prospectus and an Agent's Message is not delivered or (b)
Certificates are to be forwarded herewith. Timely confirmation of a book-entry
transfer of such Old Capital Securities into the Exchange Agent's account at
DTC, or Certificates as well as this Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, with any required signature
guarantees, and any other documents required by this Letter of Transmittal, must
be received by the Exchange Agent at its addresses set forth herein on or prior
to the Expiration Date. Tenders by book-entry transfer also may be made by
delivering an Agent's Message in lieu of this Letter of Transmittal. The term
"book-entry confirmation" means a confirmation of book-entry transfer of Old
Capital Securities into the Exchange Agent's account at DTC. The term "Agent's
Message" means a message transmitted by DTC to and received by the Exchange
Agent and forming a part of a book-entry confirmation, which states that DTC has
received an express acknowledgement from the tendering participant, which
acknowledgment states that such participant has received and agrees to be bound
by the Letter of Transmittal (including the representations contained herein)
and that the Trust and the Corporation may enforce the Letter of Transmittal
against such participant. Old Capital Securities may be tendered in whole or in
part in the Liquidation Amount of $100,000 (100 Capital Securities) and integral
multiples of $1,000 in excess thereof, provided that, if any Old Capital
Securities are tended for exchange in part, the untendered Liquidation Amount
thereof must be $100,000 (100 Capital Securities) or any integral multiple of
$1,000 in excess thereof.

      Holders who wish to tender their Old Capital Securities and (i) who cannot
complete the procedures for delivery by book-entry transfer on or prior to the
Expiration Date, (ii) who cannot deliver their Old Capital Securities, this
Letter of Transmittal and all other required documents to the Exchange Agent on
or prior to the Expiration Date or (iii) whose Old Capital Securities are not
immediately available, may tender their Old Capital Securities by properly
completing and duly executing a Notice of Guaranteed Delivery pursuant to the
guaranteed delivery procedures set forth under "The Exchange Offer--Procedures
for Tendering Old Capital Securities" in the Prospectus. Pursuant to such
procedures: (a) such tender must be made by or through an Eligible Institution
(as defined below); (b) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form made available by the
Corporation, must be received by the Exchange Agent on or prior to the
Expiration Date; and (c) the Certificates (or a book-entry confirmation (as
defined above and in the Prospectus)) representing all tendered Old Capital
Securities, in proper form for transfer, together with a Letter of Transmittal
(or facsimile thereof), properly completed and duly executed, with any required
signature guarantees and any other documents required by this Letter of
Transmittal, must be received by the Exchange Agent within three New York Stock
Exchange, Inc. trading days after the date of execution of such Notice of
Guaranteed Delivery, all as provided in "The Exchange Offer--Procedures for
Tendering Old Capital Securities" in the Prospectus.

      The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by facsimile or mail to the Exchange Agent, and must include a guarantee by an
Eligible Institution in the form set forth in such Notice. For Old Capital
Securities to be properly tendered pursuant to the guaranteed delivery
procedure, the Exchange Agent must receive a Notice of Guaranteed Delivery on or
prior to the Expiration Date. As used herein and in the Prospectus, "Eligible
Institution" means a firm or other entity identified in Rule 17Ad-15 under the
Exchange Act as "an eligible guarantor institution," including (as such terms
are defined therein) (i) a bank; (ii) a broker, dealer, municipal securities
broker or dealer or government securities broker or dealer; (iii) a credit
union; (iv) a national securities exchange, registered securities association or
clearing agency; or (v) a savings association that is a participant in a
Securities Transfer Association.

THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER AND
THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, OR OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.


                                        9
<PAGE>   10
      Neither the Corporation nor the Trust will accept any alternative,
conditional or contingent tenders. Each tendering holder, by execution of a
Letter of Transmittal (or facsimile thereof), waives any right to receive any
notice of the acceptance of such tender.

      2. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of
Transmittal is required if:

      (i) this Letter of Transmittal is signed by the registered holder (which
term, for purposes of this document, shall include any participant in DTC whose
name appears on a security position listing as the owner of the Old Capital
Securities) of Old Capital Securities tendered herewith, unless such holder(s)
has completed either the box entitled "Special Issuance Instructions" or the box
entitled "Special Delivery Instructions" above, or

        (ii) such Old Capital Securities are tendered for the account of a firm
that is an Eligible Institution.

      In all other cases, an Eligible Institution must guarantee the
signature(s) on this Letter of Transmittal. See Instruction 5.

      3. INADEQUATE SPACE. If the space provided in the box captioned
"Description of Old Capital Securities" is inadequate, the Certificate number(s)
and/or the Liquidation Amount of Old Capital Securities and any other required
information should be listed on a separate signed schedule which is attached to
this Letter of Transmittal.

      4. PARTIAL TENDERS AND WITHDRAWAL RIGHTS. Tenders of Old Capital
Securities will be accepted only in the principal amount of $100,000 (100
Capital Securities) and integral multiples of $1,000 in excess thereof, provided
that if any Old Capital Securities are tendered for exchange in part, the
untendered principal amount thereof must be $100,000 (100 Capital securities) or
any integral multiple of $1,000 in excess thereof. If less than all the Old
Capital Securities evidenced by any Certificate submitted are to be tendered,
fill in the Liquidation Amount of Old Capital Securities which are to be
tendered in the box entitled "Liquidation Amount of Old Capital Securities
Tendered (if less than all are tendered)." In such case, a new Certificate(s)
for the remainder of the Old Capital Securities that were evidenced by your Old
Certificate(s) will be sent to the holder of the Old Capital Securities,
promptly after the Expiration Date, unless the appropriate boxes on this Letter
of Transmittal are completed. All Old Capital Securities represented by
Certificates delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.

      Except as otherwise provided herein, tenders of Old Capital Securities may
be withdrawn at any time on or prior to the Expiration Date. In order for a
withdrawal to be effective on or prior to that time, a written or facsimile
transmission of such notice of withdrawal must be received by the Exchange Agent
at one of its addresses set forth above or in the Prospectus on or prior to the
Expiration Date. Any such notice of withdrawal must specify the name of the
person who tendered the Old Capital Securities to be withdrawn, the aggregate
Liquidation Amount of Old Capital Securities to be withdrawn, and (if
Certificates for Old Capital Securities have been tendered) the name of the
registered holder of the Old Capital Securities as set forth on the Certificate
for the Old Capital Securities, if different from that of the person who
tendered such Old Capital Securities. If Certificates for the Old Capital
Securities have been delivered or otherwise identified to the Exchange Agent,
then prior to the physical release of such Certificates for the Old Capital
Securities, the tendering holder must submit the serial numbers shown on the
particular Certificates for the Old Capital Securities to be withdrawn and the
signature on the notice of withdrawal must be guaranteed by an Eligible
Institution, except in the case of Old Capital Securities tendered for the
account of an Eligible Institution. If Old Capital Securities have been tendered
pursuant to the procedures for book-entry transfer set forth under "The Exchange
Offer--Procedures for Tendering Old Capital Securities" in the Prospectus, the
notice of withdrawal must specify the name and number of the account at DTC to
be credited with the withdrawal of Old Capital Securities, in which case a
notice of withdrawal will be effective if delivered to the Exchange Agent by
written or facsimile transmission on or prior to the Expiration Date.
Withdrawals of tenders of Old Capital Securities may not be rescinded. Old
Capital Securities properly withdrawn will not be deemed validly tendered for
purposes of the Exchange Offer, but may be retendered at any subsequent time on
or prior to the Expiration Date by following any of the procedures described in
the Prospectus under "The Exchange Offer--Procedures for Tendering Old Capital
Securities."

      All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Corporation and
the Trust, in their sole discretion, whose determination shall be final and
binding on all parties. None of the Corporation, the Trust, any affiliates or
assigns of the Corporation and the Trust, the Exchange Agent nor any other
person shall be under any duty to give any notification of any irregularities in
any


                                       10
<PAGE>   11
notice of withdrawal or incur any liability for failure to give any such
notification. Any Old Capital Securities which have been tendered but which are
withdrawn will be returned to the holder thereof without cost to such holder
promptly after withdrawal.

      5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Old
Capital Securities tendered hereby, the signature(s) must correspond exactly
with the name(s) as written on the face of the Certificate(s) without
alteration, enlargement or any change whatsoever.

      If any of the Old Capital Securities tendered hereby are owned of record
by two or more joint owners, all such owners must sign this Letter of
Transmittal.

      If any tendered Old Capital Securities are registered in different name(s)
on several Certificates, it will be necessary to complete, sign and submit as
many separate Letters of Transmittal (or facsimiles thereof) as there are
different registrations of Certificates.

      If this Letter of Transmittal or any Certificates or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing and must submit proper
evidence satisfactory to the Corporation and the Trust, in their sole
discretion, of such persons' authority to so act.

      When this Letter of Transmittal is signed by the registered holder(s) of
the Old Capital Securities listed and transmitted hereby, no endorsement(s) of
Certificate(s) or separate bond power(s) are required unless New Capital
Securities are to be issued in the name of a person other than the registered
holder(s). Signature(s) on such Certificate(s) or bond power(s) must be
guaranteed by an Eligible Institution.

      If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Old Capital Securities listed, the Certificates must
be endorsed or accompanied by appropriate bond powers, signed exactly as the
name or names of the registered owner(s) appear(s) on the Certificates, and also
must be accompanied by such opinions of counsel, certifications and other
information as the Corporation, the Trust or the Exchange Agent may require in
accordance with the restrictions on transfer applicable to the Old Capital
Securities. Signatures on such Certificates or bond powers must be guaranteed by
an Eligible Institution.

      6. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If New Capital Securities
are to be issued in the name of a person other than the signer of this Letter of
Transmittal, or if New Capital Securities are to be sent to someone other than
the signer of this Letter of Transmittal or to an address other than that shown
above, the appropriate boxes on this Letter of Transmittal should be completed.
Certificates for Old Capital Securities not exchanged will be returned by mail
or, if tendered by book-entry transfer, by crediting the account indicated above
maintained at DTC. See Instruction 4.

      7. IRREGULARITIES. The Corporation and the Trust will determine, in their
sole discretion, all questions as to the form of documents, validity,
eligibility (including time of receipt) and acceptance for exchange of any
tender of Old Capital Securities, which determination shall be final and binding
on all parties. The Corporation and the Trust reserve the absolute right, in
their sole and absolute discretion, to reject any and all tenders determined by
either of them not to be in proper form or the acceptance of which, or exchange
for, may, in the view of counsel to the Corporation and the Trust, be unlawful.
The Corporation and the Trust also reserve the absolute right, subject to
applicable law, to waive any of the conditions of the Exchange Offer set forth
in the Prospectus under "The Exchange Offer--Certain Conditions to the Exchange
Offer" or any conditions or irregularity in any tender of Old Capital Securities
of any particular holder whether or not similar conditions or irregularities are
waived in the case of other holders. The Corporation's and the Trust's
interpretation of the terms and conditions of the Exchange Offer (including this
Letter of Transmittal and the instructions hereto) will be final and binding. No
tender of Old Capital Securities will be deemed to have been validly made until
all irregularities with respect to such tender have been cured or waived. None
of the Corporation, the Trust, any affiliates or assigns of the Corporation, the
Trust, the Exchange Agent, or any other person shall be under any duty to give
notification of any irregularities in tenders or incur any liability for failure
to give such notification.

<PAGE>   12
      8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions and
requests for assistance may be directed to the Exchange Agent at its address and
telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, this Letter of Transmittal and the Notice
of Guaranteed Delivery may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.

      9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under U.S. Federal income
tax law, a holder whose tendered Old Capital Securities are accepted for
exchange is required to provide the Exchange Agent with such holder's correct
taxpayer identification number ("TIN") on Substitute Form W-9 below. If the
Exchange Agent is not provided with the correct TIN, the Internal Revenue
Service (the "IRS") may subject the holder or other payee to a $50 penalty. In
addition, payments to such holders or other payees with respect to Old Capital
Securities exchanged pursuant to the Exchange Offer may be subject to 31% backup
withholding.

      The box in Part 2 of the Substitute Form W-9 may be checked if the
tendering holder has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future. If the box in Part 2 is checked, the
holder or other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 2 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Exchange Agent. The Exchange Agent will retain such amounts
withheld during the 60 day period following the date of the Substitute Form W-9.
If the holder furnishes the Exchange Agent with its TIN within 60 days after the
date of the Substitute Form W-9, the amounts retained during the 60 day period
will be remitted to the holder and no further amounts shall be retained or
withheld from payments made to the holder thereafter. If, however, the holder
has not provided the Exchange Agent with its TIN within such 60 day period,
amounts withheld will be remitted to the IRS as backup withholding. In addition,
31% of all payments made thereafter will be withheld and remitted to the IRS
until a correct TIN is provided.

      The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Old Capital Securities or of the last transferee appearing on the transfers
attached to, or endorsed on, the Old Capital Securities. If the Old Capital
Securities are registered in more than one name or are not in the name of the
actual owner, consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
number to report.

      Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the face
thereof, to avoid possible erroneous backup withholding. A foreign person may
qualify as an exempt recipient by submitting a properly completed IRS Form W-8,
signed under penalties of perjury, attesting to that holder's exempt status.
Please consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
holders are exempt from backup withholding.

      Backup withholding is not an additional U.S. Federal income tax. Rather,
the U.S. Federal income tax liability of a person subject to backup withholding
will be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained.

      10. LOST, DESTROYED OR STOLEN CERTIFICATES. If any Certificate(s)
representing Old Capital Securities have been lost, destroyed or stolen, the
holder should promptly notify the Exchange Agent. The holder will then be
instructed as to the steps that must be taken in order to replace the
Certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost, destroyed or stolen
Certificate(s) have been followed.

      11. SECURITY TRANSFER TAXES. Holders who tender their Old Capital
Securities for exchange will not be obligated to pay any transfer taxes in
connection therewith. If, however, New Capital Securities are to be delivered
to, or are to be issued in the name of, any person other than the registered
holder of the Old Capital Securities tendered, or if a transfer tax is imposed
for any reason other than the exchange of Old Capital Securities in connection
with the Exchange Offer, then the amount of any such transfer tax (whether
imposed on the registered holder or any other persons) will be payable by the
tendering holder. If satisfactory evidence of payment of such taxes or exemption


                                       12
<PAGE>   13
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering holder.

      IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF) AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO THE
EXPIRATION DATE.

has not been issued to me, and either (1) I have mailed or delivered an
application to receive a taxpayer identification number to the appropriate
Internal Revenue Service Center or Social Security Administration Office or (2)
I intend to mail or deliver an application in the near future. I understand that
if I do not provide a taxpayer identification number by the time of payment, 31%
of all payments made to me on account of the New Capital Securities shall be
retained until I provide a taxpayer identification number to the Exchange Agent
and that, if I do not provide my taxpayer identification number within 60 days,
such retained amounts shall be remitted to the Internal Revenue Service as
backup withholding and 31% of all reportable payments made to me thereafter will
be withheld and remitted to the Internal Revenue Service until I provide a
taxpayer identification number.
