       THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M.,
          NEW YORK CITY TIME, ON             , 1997, UNLESS EXTENDED.
 
     Star Capital I, a Delaware statutory business trust (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 $150,000,000 aggregate
liquidation amount of its Floating Rate 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 Floating Rate Capital Securities (the "Old Capital
Securities"), of which $150,000,000 aggregate liquidation amount is outstanding.
As soon as practicable after the Exchange Offer, Star Banc Corporation, an Ohio
corporation (the "Company"), will exchange its guarantee of the payment of
distributions and payments on liquidation or redemption of the Old Capital
Securities (the "Old Guarantee") for a like guarantee of the New Capital
Securities (the "New Guarantee") and all of its Floating Rate Junior
Subordinated Debentures (the "Old Junior Subordinated Debentures"), of which
$154,640,000 aggregate principal amount is outstanding, for a like aggregate
principal amount of its Floating Rate Junior Subordinated Debentures (the "New
Junior Subordinated Debentures"), which New Guarantee and New Junior
Subordinated Debentures also have been registered under the Securities Act (the
exchange of the Old Capital Securities for the New Capital Securities, the
exchange of the Old Guarantee for the New Guarantee and the exchange of the Old
Junior Subordinated Debentures for the New Junior Subordinated Debentures is
referred to collectively herein as the "Exchange"). 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 the New Securities have
been registered under the Securities Act and therefore will not be subject to
certain restrictions on transfer applicable to the Old Securities and will not
be entitled to any increase in the distribution rate thereon or any further
registration rights under the Securities Act, except in certain limited
circumstances. See "Description of the Old Securities."
 
     The New Capital Securities and the Old Capital Securities (together, the
"Capital Securities") represent undivided beneficial ownership interests in the
assets of the Trust. The Company is the owner of all of the beneficial ownership
interests represented by common securities of the Trust (the "Common
Securities"; 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 Old Junior Subordinated Debentures, which will be
exchanged for New Junior Subordinated Debentures (together, the "Junior
Subordinated Debentures"). The Junior Subordinated Debentures will mature on
June 15, 2027. The terms of the Capital Securities provide that they will have a
preference under certain circumstances with respect to cash distributions and
amounts payable on liquidation, redemption or otherwise over the Common
Securities. See "Description of Capital Securities -- Subordination of Common
Securities."
 
     SEE "RISK FACTORS" COMMENCING ON PAGE 15 FOR CERTAIN INFORMATION THAT
SHOULD BE CONSIDERED BY HOLDERS WHO TENDER OLD CAPITAL SECURITIES IN THE
EXCHANGE OFFER.
 
 THESE SECURITIES WILL NOT BE DEPOSITS OR OTHER OBLIGATIONS OF A BANK AND WILL
    NOT BE 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 ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.
 
                            ------------------------
 
                The date of this Prospectus is           , 1997.
<PAGE>   3
 
     Holders of the Capital Securities are entitled to receive cumulative cash
distributions accruing from the date of original issuance and payable quarterly
in arrears on the fifteenth day of March, June, September and December of each
year (each, an "Interest Payment Date"), commencing September 15, 1997, at a
variable annual rate equal to LIBOR (as defined herein) plus 0.765% of the
liquidation amount of $1,000 per Capital Security ("Distributions"). The
distribution rate and the distribution payment dates and other payment dates for
the Capital Securities correspond to the payments and payment dates on the
Junior Subordinated Debentures, which will be the sole assets of the Trust. The
Company will guarantee the payment of Distributions and payments on liquidation
of the Trust or redemption of the Capital Securities, but only in each case to
the extent of funds held by the Trust, as described herein (the "Guarantee").
See "Description of Guarantee" herein. If the Company does not make interest
payments on the Junior Subordinated Debentures held by the Trust, the Trust will
have insufficient funds to pay Distributions on the Capital Securities. The
Company's obligations under the Guarantee, taken together with its obligations
under the Junior Subordinated Debentures and the Indenture (as defined herein),
including its obligation to pay all costs, expenses and liabilities of the Trust
(other than with respect to the Capital Securities), constitute a full and
unconditional guarantee of all of the Trust's obligations under the Capital
Securities. The obligations of the Company under the Guarantee and the Junior
Subordinated Debentures are subordinate and junior in right of payment to all
Indebtedness (as defined in "Description of Junior Subordinated
Debentures -- Subordination" herein) of the Company and structurally
subordinated to all liabilities and obligations of the Company's subsidiaries.
As of June 30, 1997, approximately $152 million aggregate principal amount of
Indebtedness was outstanding, and the Company's consolidated subsidiaries had
approximately $9.9 billion of indebtedness and other liabilities. The terms of
the Junior Subordinated Debentures place no limitation on the amount of
Indebtedness that may be incurred by the Company or on the amount of liabilities
and obligations of the Company's subsidiaries. See "Description of Junior
Subordinated Debentures -- Subordination."
 
     The Company has the right to defer payment of interest on the Junior
Subordinated Debentures at any time or from time to time for a period not
exceeding 20 consecutive quarterly periods with respect to each deferral period
(each, an "Extension Period"), provided that no Extension Period may extend
beyond the Stated Maturity (as defined herein) of the Junior Subordinated
Debentures. Upon the termination of any such Extension Period and the payment of
all amounts then due on any Interest Payment Date, the Company may elect to
begin a new Extension Period subject to the requirements set forth herein.
Accordingly, there could be multiple Extension Periods of varying lengths
throughout the term of the Junior Subordinated Debentures. If interest payments
on the Junior Subordinated Debentures are so deferred, distributions on the
Capital Securities will also be deferred and the Company may not, and may not
permit any subsidiary of the Company to, subject to certain exceptions described
herein, (i) declare or pay any dividends or distributions on, or redeem,
purchase, acquire, or make a liquidation payment with respect to, the Company's
capital stock or (ii) make any payment of principal, interest or premium, if
any, on or repay, repurchase or redeem any debt securities of the Company that
rank pari passu with or junior to the Junior Subordinated Debentures or make any
guarantee payments with respect to any guarantee by the Company of the debt
securities of any subsidiary of the Company if such guarantee ranks pari passu
with or junior to the Junior Subordinated Debentures (other than (a)
repurchases, redemptions or other acquisitions of shares of capital stock of the
Company in connection with any employment contract, benefit plan or other
similar arrangement with or for the benefit of any one or more employees,
officers, directors or consultants or in connection with a dividend reinvestment
or stockholder stock purchase plan, (b) as a result of an exchange or conversion
of any class or series of the Company's capital stock (or any capital stock of a
subsidiary of the Company) for any class or series of the Company's capital
stock or of any class or series of the Company's indebtedness for any class or
series of the Company's capital stock, (c) the purchase of fractional interests
in shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
(d) any declaration of a dividend in connection with the adoption of any
stockholder's rights plan, or the issuance of rights, stock or other property
under any stockholder's rights plan, or the redemption or repurchase of rights
pursuant thereto, or (e) any dividend in the form of stock, warrants, options or
other rights where the dividend stock or the stock issuable upon exercise of
such warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock). During
an Extension Period, interest on the Junior Subordinated Debentures will
continue to accrue (and the
 
                                        2
<PAGE>   4
 
amount of Distributions to which holders of the Capital Securities are entitled
will accumulate) at the variable rate of LIBOR plus 0.765% per annum, compounded
quarterly, and holders of the Capital Securities will be required to include
such interest income in gross income (as original issue discount ("OID")) for
United States federal income tax purposes prior to receipt of the cash related
to such interest income. See "Description of Junior Subordinated
Debentures -- Option to Extend Interest Payment Period" and "Certain United
States Federal Income Tax Consequences -- Interest Income and Original Issue
Discount."
 
     The Junior Subordinated Debentures are not redeemable prior to June 15,
2007 unless a Special Event (as defined herein) has occurred. The Junior
Subordinated Debentures are redeemable prior to maturity at the option of the
Company, subject to the receipt of any necessary prior approval of the Board of
Governors of the Federal Reserve System (the "Federal Reserve") (i) on or after
June 15, 2007, in whole or in part, at a redemption price equal to 100% of the
principal amount thereof, plus the accrued and unpaid interest thereon, or (ii)
at any time, in whole (but not in part), upon the occurrence and continuation of
a Special Event, at a redemption price equal to 100% of the principal amount
thereof plus the accrued and unpaid interest thereon, in each case subject to
the further conditions described under "Description of Junior Subordinated
Debentures -- Redemption." The Capital Securities are subject to mandatory
redemption, in whole or in part, upon repayment of the Junior Subordinated
Debentures at maturity or their earlier redemption, in an amount equal to the
amount of related Junior Subordinated Debentures maturing or being redeemed and
at a redemption price equal to the redemption price of such Junior Subordinated
Debentures, in each case plus accumulated and unpaid Distributions thereon to
the date of redemption.
 
     Upon the occurrence and continuation of a Special Event, the Company will
have the right, subject to the receipt of any necessary prior approval of the
Federal Reserve, to dissolve the Trust and cause the Junior Subordinated
Debentures to be distributed to the holders of the Capital Securities and the
Common Securities in liquidation of the Trust. See "Description of Capital
Securities -- Redemption -- Special Event Redemption or Distribution of Junior
Subordinated Debentures."
 
     In the event of the liquidation of the Trust, after satisfaction of the
claims of creditors of the Trust, if any, as provided by applicable law, the
holders of the Capital Securities 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
such amount in Junior Subordinated Debentures as described above. If such
Liquidation Distribution (as defined herein) can be paid only in part because
the Trust has insufficient assets available to pay in full the aggregate
Liquidation Distribution, then the amounts payable directly by the Trust on the
Capital Securities shall be paid on a pro rata basis. The holder(s) of the
Common Securities will be entitled to receive distributions upon any such
liquidation pro rata with the holders of the Capital Securities, except that if
an Indenture Event of Default (as defined herein) has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities. See "Description of Capital Securities -- Liquidation Distribution
Upon Dissolution."
 
     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 Company 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, and subject to the two immediately following sentences, the
Company 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 Company or the
Trust (within the meaning of Rule 405 under the Securities Act) or who intends
to participate in the Exchange Offer for the purpose of distributing New Capital
Securities, or any
 
                                        3
<PAGE>   5
 
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, (a) 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, (b) will not
be permitted or entitled to tender such Old Capital Securities in the Exchange
Offer and (c) 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, if any 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 broker-dealer must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resales of such New Capital Securities.
 
     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 Company 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) 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. In addition, the Company
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 Company 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 the Capital Securities to be exchanged in the Exchange Offer. Each
broker-dealer that receives New Capital Securities for its own account pursuant
to the Exchange Offer must acknowledge 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 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 Company and
the Trust believe that broker-dealers who acquired Old Capital Securities for
their own accounts, as a result of market-making activities or other trading
activities ("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 this Prospectus, as it may be amended or supplemented from time
to time. Subject to certain exceptions, the Company 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 180 days after the Registration

                             Offer -- Withdrawal Rights."

  Old Capital Securities...  Tendering holders of Old Capital Securities must
                             complete and sign a Letter of Transmittal in
                             accordance with the instructions contained therein
                             and forward the same by mail, facsimile or hand
                             delivery, together with any other required
                             documents, to the Exchange Agent, either with the
                             Old Capital Securities to be tendered or in
                             compliance with the specified procedures for
                             guaranteed delivery of Old Capital Securities.
                             Certain brokers, dealers, commercial banks, trust
                             companies and other nominees may also effect
                             tenders by book-entry transfer, including an
                             Agent's Message if the tendering holder does not
                             deliver a Letter of Transmittal. Holders of Old
                             Capital Securities registered in the name of a
                             broker, dealer, commercial bank, trust company or
                             other nominee are urged to contact such person
                             promptly if they wish to tender Old Capital
                             Securities pursuant to the Exchange Offer. See "The
                             Exchange Offer -- Procedures for Tendering Old
                             Capital Securities."
 
                             Letters of Transmittal and certificates
                             representing Old Capital Securities should not be
                             sent to the Company or the Trust. Such documents
                             should only be sent to the Exchange Agent.
                             Questions regarding how to tender and requests for
                             information should be directed to the Exchange
                             Agent. See "The Exchange Offer -- Exchange Agent."
 
Resales of New Capital
  Securities...............  The Company 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 Company 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, and subject to the two
                             immediately following sentences, the Company 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
 
                                        8
<PAGE>   10
 
                             Capital Securities who is an "affiliate" of the
                             Company 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 resell pursuant to
                             Rule 144A or any other available exemption under
                             the Securities Act, (a) 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, (b) will
                             not be permitted or entitled to tender such Old
                             Capital Securities in the Exchange Offer and (c)
                             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, if any 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
                             broker-dealer must deliver a prospectus meeting the
                             requirements of the Securities Act in connection
                             with any resales of such New Capital Securities.
 
                             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 Company 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) 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. Each broker-dealer that
                             receives New Capital Securities for its own account
                             pursuant to the Exchange Offer must acknowledge
                             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
                             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 Company and the Trust believe that
                             broker-dealers who acquired Old Capital Securities
                             for their own accounts, as a result of
                             market-making activities or other trading
                             activities ("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 this Prospectus, as it may be

                             junior in right of payment to all Indebtedness of
                             the Company. In addition, the Company's obligations
                             under the Junior Subordinated Debentures are
                             structurally subordinated to all existing and
                             future liabilities and obligations of its
                             subsidiaries. See "Risk Factors -- Ranking of

                             the redemption of Capital Securities, are
                             guaranteed by the Company to the extent the Trust
                             has funds available therefor. If the Company does
                             not make principal or interest payments on the
                             Junior Subordinated Debentures, the Trust will not
                             have sufficient

                             Securities, in which event the Guarantee shall not
                             apply to such distribution until the Trust has
                             sufficient funds available therefor. The Company's
                             obligations under the Guarantee, taken together
                             with its obligations under the Junior Subordinated
                             Debentures and the Indenture, including its
                             obligation to pay all costs, expenses and

                             to the Capital Securities), constitute a full and
                             unconditional guarantee of all of the Trust's
                             obligations under the Capital Securities. See
                             "Description of Guarantee" and "Relationship Among
                             the Capital Securities, the Junior Subordinated
                             Debentures and the Guarantee." The obligations of
                             the Company under the Guarantee are subordinate and
                             junior in right of payment to all Indebtedness of
                             the Company. See "Risk Factors -- Ranking of
                             Subordinated Obligations Under the Guarantee and

Right to Defer Interest....  The Company has the right to defer payment of
                             interest on the Junior Subordinated Debentures by
                             extending the interest payment period on the Junior

                             to 20 consecutive quarterly periods. There could be
                             multiple Extension Periods of varying lengths
                             throughout the term of the Junior Subordinated
                             Debentures. If interest payments on the Junior
                             Subordinated Debentures are so deferred,
                             distributions on the Capital Securities will also
                             be deferred for an equivalent period and the
                             Company may not, and may not permit any subsidiary
                             of the Company to, subject to certain exceptions
                             set forth herein, (i) declare or pay any dividends

                             Subordinated Debentures or make any guarantee
                             payments with respect to any guarantee by the
                             Company of the debt securities of any subsidiary of
                             the Company if such guarantee ranks pari passu with
                             or junior to the Junior Subordinated Debentures

                             acquisitions of shares of capital stock of the
                             Company in connection with any employment contract,
                             benefit plan or other similar arrangement with or
                             for the benefit of any one or more employees,

                             with a dividend reinvestment or stockholder stock

                             of the Company) for any class or series of the
                             Company's capital stock or of any class or series
                             of the Company's indebtedness for any class or

                             issuable upon exercise of such warrants, options or
                             other rights is the same stock as that on which the
                             dividend is being paid or ranks pari passu with or
                             junior to such stock). During an Extension Period,

                             on the Junior Subordinated Debentures will continue
                             to accrue (and the amount of Distributions to which
                             holders of the Capital Securities are entitled will
                             accumulate) at a variable rate of LIBOR plus 0.765%
                             per annum, compounded quarterly. During an
                             Extension Period, holders of Capital Securities
                             will be required to include their allocable share
                             of the stated interest on the Junior Subordinated
                             Debentures in gross income as original issue
                             discount ("OID") even though the cash payments
                             attributable thereto have not been made. See
                             "Description of Junior Subordinated
                             Debentures -- Option to Extend Interest Payment

Redemption.................  The Junior Subordinated Debentures are redeemable
                             by the Company in whole or in part on or after June
                             15, 2007, or at any time in whole upon the
                             occurrence of a Special Event, in either case
                             subject to any necessary prior approval of the
                             Federal Reserve. If the Junior Subordinated
                             Debentures are redeemed, the Trust must redeem
                             Trust Securities (as hereinafter defined) having an
                             aggregate liquidation amount equal to the aggregate
                             principal amount of the Junior Subordinated
                             Debentures so redeemed. The Trust Securities will
                             be redeemed upon maturity of the Junior
                             Subordinated Debentures. See "Description of
                             Capital Securities -- Redemption -- Mandatory

                             Distribution of Junior Subordinated Debentures."
 
Liquidation of the Trust...  Upon the occurrence and continuation of a Special
                             Event, the Company will have the right, subject to
                             any necessary prior approval of the Federal
                             Reserve, to terminate the Trust and cause the
                             Junior Subordinated Debentures to be distributed to
                             the holders of the Capital Securities and the
                             Common Securities in liquidation of the Trust. See
                             "Description of Capital
                             Securities -- Redemption -- Special Event
                             Redemption or Distribution of Junior Subordinated
                             Debentures."
 
                             In the event of the liquidation of the Trust, after
                             satisfaction of the claims of creditors of the
                             Trust, if any, as provided by applicable law, the
                             holders of the Capital Securities 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 such amount
                             in Junior Subordinated Debentures as described
                             above. If such Liquidation Distribution can be paid
                             only in part because the Trust has insufficient
                             assets available to pay in full the aggregate
                             Liquidation Distribution, then the amounts payable
                             directly by the Trust on the Capital Securities
                             shall be paid on a pro rata basis. The holder of
                             the Common Securities will be entitled to receive
                             distributions upon any such liquidation pro rata
                             with the holders of the Capital Securities, except
                             that if an Indenture Event of Default has occurred
                             and is continuing, the Capital Securities shall
                             have a priority over the Common Securities. See
                             "Description of Capital Securities -- Liquidation
                             Distribution Upon Dissolution."
 
Ratings....................  The New Capital Securities have been rated "a3" by
                             Moody's Investors Service, Inc. ("Moody's") and
                             "BBB" by Standard & Poor's Ratings Services
                             ("S&P"). 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.

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
                             established trading market. Accordingly, there can
                             be no assurance as to the development or liquidity
                             of any market for the New Capital Securities. The
                             Company currently does 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.

                                  RISK FACTORS
 
     Prospective purchasers of the New Capital Securities should carefully
review the information contained elsewhere in this Prospectus and should
particularly consider the following matters. To the extent any of the
information contained or incorporated by reference in this Prospectus
constitutes a "forward-looking statement" as defined in Section 21E(i)(1) of the
Exchange Act, the risk factors set forth below are cautionary statements
identifying important factors that could cause actual results to differ
materially from those in the forward-looking statement.
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE JUNIOR
SUBORDINATED DEBENTURES
 
     The obligations of the Company under the Guarantee issued by the Company
for the benefit of the holders of Capital Securities and under the Junior
Subordinated Debentures are unsecured and rank subordinate and junior in right
of payment to all Indebtedness of the Company. At June 30, 1997, the
Indebtedness of the Company aggregated approximately $152 million. Neither the
Indenture, the Guarantee nor the Declaration (as defined herein) place any
limitation on the amount of secured or unsecured Indebtedness that may be
incurred by the Company. See "Description of Guarantee -- Status of the
Guarantee" and "Description of Junior Subordinated Debentures -- Subordination."
 
STATUS OF COMPANY AS HOLDING COMPANY
 
     As a holding company, the ability of the Company to make payments of
interest and principal on the Junior Subordinated Debentures will be dependent
primarily upon the receipt of dividends and other distributions from the
Company's subsidiaries. The Company's principal subsidiary is the Bank. There
are various regulatory restrictions on the ability of the Bank to pay dividends
or make other payments to the Company. At June 30, 1997, the Bank could pay an
aggregate of $157 million in dividends to the Company without prior regulatory
approval. In addition, the right of the Company to participate in any
distribution of assets of any subsidiary, including the Bank, 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),
will be subject to the prior claims of creditors of that subsidiary, except to
the extent that any claims of the Company as a creditor of such subsidiary may
be recognized as such. Accordingly, the Capital Securities will effectively be
subordinated to all existing and future liabilities of the Company's
subsidiaries, and holders of the Capital Securities should look only to the
assets of the Company for payments on the Capital Securities. As of June 30,
1997, the Company's consolidated subsidiaries had indebtedness and other
liabilities of approximately $9.9 billion.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF CAPITAL SECURITIES
 
     If a Trust Enforcement Event (as defined herein) occurs and is continuing,
then the holders of Capital Securities would rely on the enforcement by the
Property Trustee (as defined herein) of its rights as a holder of the Junior
Subordinated Debentures against the Company. The holders of 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 Property Trustee or to direct the exercise of any trust or power conferred
upon the Property Trustee under the Declaration (as defined herein), including
the right to direct the Property Trustee to exercise the remedies available to
it as a holder of the Junior Subordinated Debentures. If the Property Trustee
fails to enforce its rights with respect to the Junior Subordinated Debentures
held by the Trust, any record holder of Capital Securities may institute legal
proceedings directly against the Company to enforce the Property Trustee's
rights under such Junior Subordinated Debentures without first instituting any
legal proceedings against such Property Trustee or any other person or entity.
 
     If the Company were to default on its obligation to pay amounts payable
under the Junior Subordinated Debentures, the Trust would lack 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.
However, in the event the Company failed to pay interest on or principal of the
Junior Subordinated Debentures on the payment date on which such payment is
 
                                       15
<PAGE>   17
 
due and payable, then a holder of Capital Securities may directly institute a
proceeding against the Company for enforcement of payment to such holder of the
interest on or principal of Junior Subordinated Debentures having a principal
amount equal to the aggregate liquidation amount of the Capital Securities of
such holder (a "Direct Action"). In connection with such Direct Action, the
Company will be subrogated to the rights of such holder of Capital Securities
under the Declaration to the extent of any payment made by the Company to such
holder of Capital Securities in such Direct Action. Except as set forth herein,
holders of Capital Securities will not be able to exercise directly any other
remedy available to the holders of Junior Subordinated Debentures or assert
directly any other rights in respect of the Junior Subordinated Debentures. See
"Description of Capital Securities -- Enforcement of Certain Rights by Holders
of Capital Securities," "Description of Guarantee" and "Description of Junior
Subordinated Debentures -- Indenture Events of Default." The Declaration
provides that each holder of Capital Securities by acceptance thereof agrees to
the provisions of the Guarantee and the Indenture.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES
 
     The Company 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 20 consecutive quarterly periods, provided that no
Extension Period may extend beyond the Stated Maturity of the Junior
Subordinated Debentures. As a consequence of any such deferral, quarterly
Distributions on the Capital Securities by the Trust would be deferred but would
continue to accumulate at a variable rate of LIBOR plus 0.765% per annum,
compounded quarterly during any such Extension Period. During any such Extension
Period, the Company may not, and may not permit any subsidiary of the Company
to, (i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of the Company's
capital stock or (ii) make any payment of principal, interest or premium, if
any, on or repay, repurchase or redeem any debt securities of the Company that
rank pari passu with or junior to the Junior Subordinated Debentures or make any
guarantee payments with respect to any guarantee by the Company of the debt
securities of any subsidiary of the Company if such guarantee ranks pari passu
with or junior to the Junior Subordinated Debentures (other than (a)
repurchases, redemptions or other acquisitions of shares of capital stock of the
Company in connection with any employment contract, benefit plan or other
similar arrangement with or for the benefit of any one or more employees,
officers, directors or consultants or in connection with a dividend reinvestment
or stockholder stock purchase plan, (b) as a result of an exchange or conversion
of any class or series of the Company's capital stock (or any capital stock of a
subsidiary of the Company) for any class or series of the Company's capital
stock or of any class or series of the Company's indebtedness for any class or
series of the Company's capital stock, (c) the purchase of fractional interests
in shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
(d) any declaration of a dividend in connection with the adoption of any
stockholder's rights plan, or the issuance of rights, stock or other property
under any stockholder's rights plan, or the redemption or repurchase of rights
pursuant thereto, or (e) any dividend in the form of stock, warrants, options or
other rights where the dividend stock or the stock issuable upon exercise of
such warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock). Prior
to the termination of any such Extension Period, the Company may further extend
the Extension Period, provided that no Extension Period may exceed 20
consecutive quarterly periods or extend beyond the Stated Maturity of the Junior
Subordinated Debentures. Upon the termination of any Extension Period and the
payment of all amounts then due on any Interest Payment Date, the Company may
elect to begin a new Extension Period subject to the above requirements. See
"Description of Capital Securities -- Distributions" and "Description of Junior
Subordinated Debentures -- Option to Extend Interest Payment Period."
 
     Should the Company defer payment of interest on the Junior Subordinated
Debentures, a holder of Capital Securities will be required to accrue income (in
the form of OID) for United States federal income tax purposes in respect of its
pro rata share of the Junior Subordinated Debentures held by the Trust. As a
result, a holder of Capital Securities will be required to include such holder's
allocable share of the stated interest on the Junior Subordinated Debentures in
gross income for United States federal income tax purposes in advance of the
receipt of cash attributable to such income, and will not receive the cash
related to such
 
                                       16
<PAGE>   18
 
income from the Trust if the holder disposes of the Capital Securities prior to
the record date for the payment of Distributions with respect to such Extension
Period. See "Certain United States Federal Income Tax Consequences -- Interest
Income and Original Issue Discount" and " -- Sales of Capital Securities."
 
     The Company has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the Junior
Subordinated Debentures. However, should the Company elect to exercise such
right in the future, the market price of the Capital Securities is likely to be
adversely 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, as a
result of the existence of the Company's right to defer interest payments, the
market price of the Capital Securities (which represent preferred undivided
beneficial interests in the Junior Subordinated Debentures) may be more volatile
than the market prices of other similar securities where the issuer does not
have such right to defer interest payments.
 
SPECIAL EVENT REDEMPTION
 
     Upon the occurrence and continuation of a Special Event, the Company has
the right, subject to any necessary prior approval of the Federal Reserve, to
redeem the Junior Subordinated Debentures in whole (but not in part) at the
redemption price described in the Indenture within 90 days following the
occurrence of such Special Event and thereby cause a mandatory redemption of the
Capital Securities and Common Securities. A "Special Event" means a Tax Event, a
Regulatory Capital Event or an Investment Company Event (each as defined
herein).
 
LIQUIDATION DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES
 
     Upon the occurrence and continuation of a Special Event the Company will
have the right, subject to any necessary prior approval of the Federal Reserve,
to terminate the Trust and cause the Junior Subordinated Debentures to be
distributed to the holders of the Capital Securities and the Common Securities
in liquidation of the Trust. In addition, upon liquidation of the Trust and
certain other events, the Junior Subordinated Debentures may be distributed to
such holders. Under current United States federal income tax law and
interpretations thereof and assuming, as expected, the Trust is treated as a
grantor trust for United States federal income tax purposes, a distribution by
the Trust of the Junior Subordinated Debentures pursuant to a liquidation of the
Trust will not be a taxable event to the Trust or to holders of the Capital
Securities and will result in a holder of the Capital Securities receiving
directly such holder's pro rata share of the Junior Subordinated Debentures
(previously held indirectly through the Trust). If, however, the liquidation of
the Trust were to occur because the Trust is subject to United States federal
income tax with respect to income accrued or received on the Junior Subordinated
Debentures as a result of the occurrence of a Tax Event or otherwise, the
distribution of Junior Subordinated Debentures to holders of the Capital
Securities by the Trust could be a taxable event to the Trust and each holder,
and holders of the Capital Securities could then be required to recognize gain
or loss as if they had exchanged their Capital Securities for the Junior
Subordinated Debentures they received upon the liquidation of the Trust. See
"Certain United States Federal Income Tax Consequences -- Distribution 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
Junior Subordinated Debentures that may be distributed in exchange for Capital
Securities if a liquidation of the Trust occurs. Accordingly, the Capital
Securities that an investor may purchase, whether pursuant to the offer made
hereby or in the secondary market, or the Junior Subordinated Debentures that a
holder of Capital Securities may receive on liquidation of the Trust, may trade
at a discount to the price that the investor paid to purchase the Capital
Securities offered hereby. Because holders of Capital Securities may receive
Junior Subordinated Debentures on termination of the Trust, 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 Capital Securities -- Redemption -- Special Event Redemption or
Distribution of Junior Subordinated Debentures" and "Description of Junior
Subordinated Debentures -- General."

LIMITED VOTING RIGHTS
 
     Holders of New Capital Securities generally will have limited voting rights
relating only to the modification of the New Capital Securities and certain
other matters described herein. Holders of New Capital Securities will not be
entitled to vote to appoint, remove or replace any of the Trustees (as defined
below), which voting rights are vested exclusively in the holder of the Common
Securities. The Trustees and the Company may amend the Declaration without the
consent of holders of Capital Securities to ensure that the Trust will be
classified as a grantor trust for United States federal income tax purposes,
unless such action would materially and adversely affect the interests of such
holders. See "Description of Capital Securities -- Voting Rights; Amendment of
the Declaration" and "-- Removal of 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 that 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 that
remain outstanding will not be entitled to any increase in the distribution rate
thereon or any rights to have such Old Capital Securities registered under the
Securities Act by the Company (subject to certain limited exceptions). The
Company and the Trust do not intend to register under the Securities Act any Old
Capital Securities that remain outstanding after consummation of the Exchange
Offer (subject to such limited exceptions, if applicable).
 
     The Old Capital Securities were issued to, and the Company believes are
currently owned by, a small number of beneficial owners. To the extent that Old
Capital Securities are tendered and accepted in connection with the Exchange
Offer, any trading market for Old Capital Securities that remain outstanding
after the Exchange Offer could be adversely affected.
 
ABSENCE OF PUBLIC MARKET FOR NEW CAPITAL SECURITIES
 
     Although the New Capital Securities will generally be permitted to be
resold or otherwise transferred by the holders (who are not affiliates of the
Company 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. Accordingly, no assurance can be given that an
active public or other market will develop for the New Capital Securities or as
to the liquidity of or the trading market for the New Capital Securities. The
Company currently does 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. 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 of such securities will depend on many factors, including, among
other things, prevailing interest rates, 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
Company, the New Capital Securities may trade at a discount.
 
     Each broker-dealer that receives New Capital Securities for its own account
in exchange for Old Capital Securities, where such Old Capital Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, 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 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. The Trust is under no duty to give notification of
defects or irregularities with respect to the tenders of Old Capital Securities
for exchange.
 
                                USE OF PROCEEDS
 
     Neither the Company nor the Trust will receive any cash proceeds from the
issuance of the New Capital Securities offered hereby. The New Capital
Securities will be exchanged for Old Capital Securities of like aggregate
liquidation amount, which will be retired and cancelled. The cash proceeds from
the sale of the Old Capital Securities were used to purchase Old Junior
Subordinated Debentures. The Company intends to use the proceeds from the sale
of the Old Junior Subordinated Debentures for general corporate purposes, which
may include the repurchase of common equity of the Company, the repayment of
indebtedness, investments in or extensions of credit to its subsidiaries and the
financing of possible acquisitions. Pending such use, the net proceeds may be
temporarily invested in short-term obligations. The precise amounts and timing
of the application of proceeds will depend upon the funding requirements of the
Company and its subsidiaries and the availability of other funds.

              COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS
 
     The Company's consolidated ratios of earnings to fixed charges and
consolidated ratios of earnings to combined fixed charges and preferred stock

</TABLE>
 
     For purposes of computing the ratios of both earnings to fixed charges and
earnings to combined fixed charges and preferred stock dividend requirements,
earnings represent net income plus applicable income taxes and fixed charges.
Fixed charges, excluding interest on deposits, represent interest expense
(except interest on deposits), capitalized interest, and the interest factor
included in rents. Fixed charges, including interest on deposits, represent all
interest expense, capitalized interest, and the interest factor included in
rents. Combined fixed charges and preferred stock dividend requirements,
excluding interest on deposits, represent interest expense (except interest on
deposits), capitalized interest, an amount equal to the pre-tax earnings
required to meet applicable preferred stock dividend requirements, and the
interest factor included in rents. Combined fixed charges and preferred stock
dividend requirements, including interest on deposits, represent all interest
expense, capitalized interest, an amount equal to the pre-tax earnings required
to meet applicable preferred stock dividend requirements, and the interest
factor included in rents.

                              ACCOUNTING TREATMENT
 
     For financial reporting purposes, the Trust will be treated as a subsidiary
of the Company and, accordingly, the accounts of the Trust will be included in
the consolidated financial statements of the Company. The Capital Securities
will be presented in the consolidated balance sheet of the Company in the "Trust
Preferred Securities" line item in the liabilities section 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 Company will record
Distributions payable on the Capital Securities as interest expense in the
consolidated statements of income.
 
                              REGULATORY TREATMENT
 
     The Company is required by the Federal Reserve to maintain certain levels
of capital for bank regulatory purposes. The Company expects that the Capital
Securities will be treated as Tier 1 capital of the Company for such purposes.
 
                                 CAPITALIZATION

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
     In connection with the sale of the Old Capital Securities, the Company and
the Trust entered into a Registration Rights Agreement (the "Registration Rights
Agreement") with the Initial Purchasers of the Old Capital Securities (the
"Initial Purchasers"), pursuant to which the Company and the Trust agreed to
file and to use their reasonable efforts to cause to become effective with 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 is 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 Company 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 have been
registered under the Securities Act and therefore will not be subject to certain
restrictions on transfer applicable to the Old Capital Securities. 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, except under
certain limited circumstances. See "Risk Factors -- Consequences of a Failure to
Exchange Old Capital Securities" and "Description of Capital Securities."
 
     As soon as practicable after the Expiration Date, the Company will exchange
the Old Guarantee for the New Guarantee and all of the Old Junior Subordinated
Debentures, of which $154,640,000 aggregate principal amount is outstanding, for
a like aggregate principal of the New Junior Subordinated Debentures. The New
Guarantee and New Junior Subordinated Debentures have been registered under the
Securities Act.
 
     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. Holders of Old
Capital Securities do not have any appraisal or dissenters' rights in connection
with the Exchange Offer.
 
     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 Company or any other person who has obtained a
properly completed bond power from the registered holder, or any person whose
Old Capital Securities are held of record by The Depository Trust Company who
desires to deliver such Old Capital Securities by book-entry transfer at The
Depository Trust Company.
 
TERMS OF THE EXCHANGE
 
     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 $150,000,000 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, $1,000 liquidation amount of New Capital
Securities in exchange for each $1,000 liquidation amount of outstanding Old
Capital Securities tendered and accepted in connection with the Exchange Offer.
 
     The Exchange Offer is not conditioned upon any minimum liquidation amount
of Old Capital Securities being tendered. As of the date of this Prospectus,
$150,000,000 aggregate liquidation amount of the Old Capital Securities is
outstanding.
 
     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.
 
                                       21
<PAGE>   23
 
     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 Company will pay all charges and expenses, other than certain applicable
taxes described below, in connection with the Exchange Offer. See "-- Fees and
Expenses."
 
     Pursuant to the Letter of Transmittal or Agent's Message in lieu thereof,
each holder who tenders Old Capital Securities will warrant and agree in the
Letter of Transmittal that it has full power and authority to tender, exchange,
sell, assign and transfer the tendered 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 that 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 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.
 
     The Trust reserves the right in its sole discretion to (a) purchase or make
offers for any Old Capital Securities that remain outstanding subsequent to the
Expiration Date, or, as set forth under "-- Expiration Date; Extensions;
Amendments," to terminate the Exchange Offer and (b) to the extent permitted by
applicable law, purchase Old Capital Securities in the open market, in privately
negotiated transactions or otherwise. The terms of any such purchases or offers
may differ from the terms of the Exchange Offer.
 
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 Company and the
Trust (in which case the term "Expiration Date" shall mean the latest date and
time to which the Exchange Offer is extended).
 
     The Company 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 or
to terminate the Exchange Offer (whether or not any Old Capital Securities have
theretofore been accepted for exchange) if the Company 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, (ii) 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 (iii) to waive any condition or otherwise amend the terms of the
Exchange Offer in any respect deemed by them to be advantageous to the holders
of the Old Capital Securities. If the Exchange Offer is amended in a manner
determined by the Company and the Trust to constitute a material change, or if
the Company and the Trust waive a material condition of the Exchange Offer, the
Trust will promptly disclose such amendment by means of a prospectus supplement
that will be distributed to the registered holders of the Old Capital
Securities, and the Company 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 Trust may choose to make any public announcement and
subject to applicable law, 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.
 
RESALES OF NEW CAPITAL SECURITIES
 
     The Trust is making the Exchange Offer for the 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
 
                                       22
<PAGE>   24
 
to third parties in other transactions. However, neither the Company 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, and subject to the two immediately
following sentences, the Company 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 Company or the Trust (within the meaning of Rule 405
under the Securities Act) 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, (a) 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,
(b) will not be permitted or entitled to tender such Old Capital Securities in
the Exchange Offer and (c) 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, if any
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 broker-dealer must
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of such New Capital Securities.
 
     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 Company 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) 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. In addition, the Company
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 Company 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 broker-dealer that receives New Capital Securities for its
own account pursuant to the Exchange Offer must acknowledge 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 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
Company and the Trust believe that broker-dealers who acquired Old Capital
Securities for their own accounts, as a result of market-making activities or
other trading activities ("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 this Prospectus, as it may be amended or supplemented
from time to time. Subject to certain provisions set forth in the Registration
Rights Agreement, the Company 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 180 days after the Registration Statement of
which this Prospectus constitutes a part is declared effective. See "Plan of
Distribution." Any Participating Broker-Dealer who is an "affiliate" of the
Company or the Trust may not rely on such interpretive letters and must
 
                                       23
<PAGE>   25
 
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction.
 
     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, that, upon receipt of notice from the Company 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 Securities pursuant to this Prospectus until the
Company 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 Company or the Trust has
given notice that the sale of the New Capital Securities may be resumed, as the
case may be.
 
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
(pursuant to the withdrawal rights described under "-- Withdrawal Rights")
promptly after the Expiration Date.
 
     Subject to the terms and conditions of the Exchange Offer, 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 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 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 Company's or the Trust's rights
set forth herein, the Exchange Agent may, nevertheless, on behalf of 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."
 
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)or (in
the case of book-entry transfer) an Agent's Message in lieu of the Letter of
Transmittal, with any required signature guarantees and any other required
documents, must be received by the Exchange Agent at one of its addresses set
forth under "-- Exchange Agent," and one of the following must apply: (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 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.
 
     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,
 
                                       24
<PAGE>   26
 
which acknowledgement states that such participant has received and agrees to be
bound by the Letter of Transmittal and that the Trust and the Company may
enforce such Letter of Transmittal against such participant.
 
     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 indicated in an Agent's
Message in lieu of a Letter of Transmittal. 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 The Depository Trust Company ("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 (a) a certificate for the Old Capital Securities is
registered in a name other than that of the person surrendering the certificate
or (b) such registered holder completes the box entitled "Special Issuance
Instructions" or "Special Delivery Instructions" in the Letter of Transmittal.
In the case of (a) or (b) 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 (each, 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 before the Expiration Date, or the
procedures 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
     Expiration Date; and
 
                                       25
<PAGE>   27
 
          (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), with any required signature guarantees and any other documents
     required by the Letter of Transmittal, are received by the Exchange Agent
     within five 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, transmitted by
facsimile or mailed to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in such notice.
 
     Notwithstanding any other provisions 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 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 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 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 Trust and the Company 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 Trust, in its sole
discretion, whose determination shall be final and binding on all parties. The
Trust reserves the absolute right, in its sole and absolute discretion, to
reject any and all tenders determined by it not to be in proper form or the
acceptance of which, or exchange for which may, in the view of counsel to the
Trust, be unlawful. The Trust also reserves 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 Trust's interpretation 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. Neither the Trust, any affiliates or assigns of the Trust, the
Exchange Agent nor 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 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 Trust,
proper evidence satisfactory to the Trust, in its 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.
 
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.
 
                                       26
<PAGE>   28
 
     In order for a withdrawal to be effective a written, telegraphic, telex 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 in 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 serial 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 above under "-- 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, telegraphic, telex 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 Trust, in its sole
discretion, whose determination shall be final and binding on all parties.
Neither the Trust, any affiliates or assigns of the Trust, the Exchange Agent
nor 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 THE NEW CAPITAL SECURITIES
 
     Each New Capital Security will pay cumulative Distributions from the most
recent Distribution Date on the Old Capital Securities surrendered in exchange
for such New Capital Securities or, if no Distributions have been paid on such
Old Capital Securities, from June 8, 1997. Holders of the Old Capital Securities
whose Old Capital Securities are accepted for exchange will not receive
accumulated Distributions on such Old Capital Securities for any period from and
after the last Distribution Date on such Old Capital Securities prior to the
original issue date of the New Capital Securities or, if no such Distributions
have been paid, will not receive any accumulated 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 June 8,
1997.
 
CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other provisions of the Exchange Offer, or any
extension of the Exchange Offer, 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 Company or the Trust within the meaning of Rule 405 under the
     Securities Act) 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;
 
                                       27
<PAGE>   29
 
          (b) 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 Trust's judgment, would reasonably be
     expected to impair the ability of the Trust or the Company to proceed with
     the Exchange Offer;
 
          (c) any law, statute, rule or regulation shall have been adopted or
     enacted which, in the Trust's judgment, would reasonably be expected to
     impair the ability of the Trust or the Company to proceed with the Exchange
     Offer;
 
          (d) a banking moratorium shall have been declared by United States
     federal or New York or Ohio state authorities which, in the Trust's
     judgment, would reasonably be expected to impair the ability of the Company
     or the Trust to proceed with the Exchange Offer;
 
          (e) trading on the New York Stock Exchange or generally in the
     over-the-counter market shall have been suspended by order of the
     Commission or any other governmental authority which, in the Trust's
     judgment, would reasonably be expected to impair the ability of the Trust
     or the Company to proceed with the Exchange Offer;
 
          (f) a stop order shall have been issued by the Commission or any state
     securities authority suspending the effectiveness of the Registration
     Statement or proceedings shall have been initiated or, to the knowledge of
     the Company or the Trust, threatened for that purpose or any governmental
     approval has not been obtained, which approval the Trust shall, in its sole
     discretion, deem necessary for the consummation of the Exchange Offer as
     contemplated hereby; or
 
          (g) any change, or any development involving a prospective change, in
     the business or financial affairs of the Company or any of its subsidiaries
     has occurred which, in the sole judgment of the Trust, might materially
     impair the ability of the Trust or the Company to proceed with the Exchange
     Offer.
 
     If the Company and the Trust determine in their sole and absolute
discretion that any of the foregoing events or conditions has occurred or exists
or has not been satisfied, the Company and the Trust may, subject to applicable
law, terminate the Exchange Offer (whether or not any Old Capital Securities
have theretofore been accepted for exchange) or may waive any such condition or
otherwise amend the terms of the Exchange Offer in any respect. If such waiver
or amendment constitutes a material change to the Exchange Offer, the Company
and the Trust will promptly disclose such waiver by means of a prospectus
supplement that will be distributed to the registered holders of the Old Capital
Securities, and the Company and the Trust will extend the Exchange Offer to the
extent and in the manner required by Rule 14e-1 under the Exchange Act.

FEES AND EXPENSES
 
     The Company 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 Company 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 Company nor the Trust will make any payment to brokers, dealers
or others for soliciting acceptances of the Exchange Offer.
 
                                   THE TRUST
 
     The Trust is a statutory business trust formed under the Delaware Business
Trust Act, as amended (the "Trust Act"), pursuant to a declaration of trust (as
so amended and restated, the "Declaration") and the filing of a certificate of
trust as filed with the Secretary of State of the State of Delaware. The Company
acquired Common Securities in an aggregate liquidation amount equal to at least
3% of the total capital of the Trust. The Trust used all the proceeds derived
from the issuance of the Old Capital Securities and the Common Securities to
purchase the Junior Subordinated Debentures and, accordingly, the assets of the
Trust consist solely of the Junior Subordinated Debentures. The Trust exists for
the exclusive purpose of (i) issuing the Trust Securities representing undivided
beneficial ownership interests in the assets of the Trust, (ii) investing the
gross proceeds of the Trust Securities in the Junior Subordinated Debentures,
and (iii) engaging in only those other activities necessary or incidental
thereto.
 
     Pursuant to the Declaration, there initially are five trustees (the
"Trustees") for the Trust. Three of the Trustees (the "Regular Trustees") are
individuals who are employees or officers of or who are affiliated with the
Company. The fourth trustee is required to be a financial institution that is
unaffiliated with the Company (the "Property Trustee"). The fifth trustee is
required to be an entity that maintains its principal place of business in the
State of Delaware (the "Delaware Trustee"). Initially, The First National Bank
of Chicago, a national banking association, is acting as Property Trustee, and
its affiliate, First Chicago Delaware Inc., a Delaware corporation, is acting as
Delaware Trustee until, in each case, removed or replaced by the Company as
holder of the Common Securities. The First National Bank of Chicago is also
acting as trustee under the Guarantee (the "Guarantee Trustee").
 
     The Property Trustee holds title to the Junior Subordinated Debentures for
the benefit of the holders of the Trust Securities, and the Property Trustee
will have the power to exercise all rights, powers and privileges with respect
to the Junior Subordinated Debentures under the Indenture (as defined herein) as
the holder of the Junior Subordinated Debentures. In addition, the Property
Trustee will maintain exclusive control of a non-interest bearing bank account
(the "Property Account"), which will not be segregated from other funds except
to the extent required by law, to hold all payments made in respect of the
Junior Subordinated Debentures for the benefit of the holders of the Trust
Securities. The Guarantee Trustee holds the Guarantee for the benefit of the
holders of the Capital Securities. The Company, as the holder of all the Common
Securities, will have the right to appoint, remove or replace any of the
Trustees and to increase or decrease the number of Trustees, provided that the
number of Trustees shall be at least three; provided further that at least one
Trustee shall be a Delaware Trustee, at least one trustee shall be the Property
Trustee and at least one Trustee shall be a Regular Trustee. Under the
Indenture, the Company, as borrower, is required to pay all fees
 
                                       29
<PAGE>   31
 
and expenses related to the organization and operations of the Trust (including
any taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States or any other domestic
taxing authority upon the Trust) and the offering of the Capital Securities and
be responsible for all debts and obligations of the Trust (other than with
respect to the Common Securities and the Capital Securities).
 
     For so long as the Capital Securities remain outstanding, the Company has
covenanted (i) to maintain directly or indirectly 100% ownership of the Common
Securities, (ii) to cause the Trust to remain a statutory business trust and not
to voluntarily dissolve, wind-up, liquidate or be terminated, except as
permitted by the Declaration, (iii) to use its commercially reasonable efforts
to ensure that the Trust will not be an "investment company" for purposes of the
Investment Company Act of 1940, as amended, and (iv) to take no action that
would be reasonably likely to cause the Trust to be classified as an association
or a publicly traded partnership taxable as a corporation for United States
federal income tax purposes.
 
     The rights of the holders of the Capital Securities, including economic
rights, rights to information and voting rights, are set forth in the
Declaration and the Trust Indenture Act. See "Description of Capital
Securities." The Declaration and the Guarantee also incorporate by reference the
terms of the Trust Indenture Act.
 
     The location of the principal executive office of the Trust is c/o Star
Banc Corporation, 425 Walnut Street, Cincinnati, Ohio 45202, and its telephone
number is (513) 632-4000.
 
                       DESCRIPTION OF CAPITAL SECURITIES
 
     Pursuant to the terms of the Declaration, the Regular Trustees on behalf of
the Trust have issued the Old Capital Securities and the Common Securities. The
Old Capital Securities represent, and the New Capital Securities will represent,
undivided beneficial ownership interests in the assets of the Trust and the
holders thereof will be entitled to a preference in certain circumstances with
respect to Distributions and amounts payable on redemption or liquidation over
the Common Securities, as well as other benefits as described in the
Declaration. This summary of certain provisions of the Capital Securities and
the Declaration 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, and the Trust
Indenture Act. Wherever particular defined terms of the Declaration (as
supplemented or amended from time to time) are referred to herein, the
definitions of such defined terms are incorporated herein by reference.
 
GENERAL
 
     The Capital Securities rank pari passu, and payments will be made thereon
pro rata, with the Common Securities except as described under "-- Subordination
of Common Securities." Legal title to the Junior Subordinated Debentures will be
held by the Property Trustee in trust for the benefit of the holders of the
Capital Securities and the Common Securities. The Guarantee executed by the
Company for the benefit of the holders of the Capital Securities is a guarantee
on a subordinated basis with respect to the Capital Securities but will not
guarantee payment of Distributions or amounts payable on redemption or
liquidation of the Capital Securities when the Trust does not have sufficient
funds available to make such payments. See "Description of Guarantee." In such
event, the remedy of a holder of Capital Securities is to vote to direct the
Property Trustee to enforce the Property Trustee's rights under the Junior
Subordinated Debentures. See "-- Voting Rights; Amendment of the Declaration"
below. The Company's obligations under the Guarantee, taken together with its
obligations under the Junior Subordinated Debentures and the Indenture,
including its obligation to pay all costs, expenses and liabilities of the Trust
(other than with respect to the Common Securities and the Capital Securities),
constitute a full and unconditional guarantee of all of the Trust's obligations
under the Capital Securities.
 
     Holders of the Capital Securities have no preemptive or similar rights.
 
                                       30
<PAGE>   32
 
DISTRIBUTIONS
 
     Distributions on each Capital Security will be payable at a variable annual
rate of LIBOR plus 0.765% of the liquidation amount of $1,000, payable quarterly
in arrears on March 15, June 15, September 15 and December 15 of each year.
Distributions will accumulate from June 8, 1997, the date of original issuance,
and commence on September 15, 1997. The amount of Distributions payable for any
period will be computed on the basis of the actual number of days elapsed in a
year of twelve 30-day months.
 
     Distributions on the Capital Securities must be paid on the dates payable
to the extent that the Trust has funds available for the payment of such
distributions. The revenue of the Trust available for distribution to holders of
its Capital Securities will be limited to payments under the Junior Subordinated
Debentures. See "Description of Junior Subordinated Debentures." If the Company
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 Company 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 20 consecutive quarterly periods (each, an "Extension
Period"), provided that no Extension Period may extend beyond the Stated
Maturity (as defined below) of the Junior Subordinated Debentures. As a
consequence of any such extension, quarterly 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 will
accumulate and compound quarterly at a variable rate per annum of LIBOR plus
0.765% thereof from the relevant payment date for such Distributions. The term
"Distributions" as used herein shall include any such compounded amounts unless
the context otherwise requires. During any such Extension Period, the Company
may not, and may not permit any subsidiary of the Company to, (i) declare or pay
any dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Company's capital stock or (ii)
make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Company that rank pari passu
with or junior to the Junior Subordinated Debentures or make any guarantee
payments with respect to any guarantee by the Company of the debt securities of
any subsidiary of the Company if such guarantee ranks pari passu with or junior
in interest to the Junior Subordinated Debentures (other than (a) repurchases,
redemptions or other acquisitions of shares of capital stock of the Company in
connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of any one or more employees, officers,
directors or consultants or in connection with a dividend reinvestment or
stockholder stock purchase plan, (b) as a result of an exchange or conversion of
any class or series of the Company's capital stock (or any capital stock of a
subsidiary of the Company) for any class or series of the Company's capital
stock or of any class or series of the Company's indebtedness for any class or
series of the Company's capital stock, (c) the purchase of fractional interests
in shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
(d) any declaration of a dividend in connection with the adoption of any
stockholder's rights plan, or the issuance of rights, stock or other property
under any stockholder's rights plan, or the redemption or repurchase of rights
pursuant thereto, or (e) any dividend in the form of stock, warrants, options or
other rights where the dividend stock or the stock issuable upon exercise of
such warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock). Prior
to the termination of any such Extension Period, the Company may further extend
the Extension Period, provided that no Extension Period may exceed 20
consecutive quarterly periods or extend beyond the Stated Maturity of the Junior
Subordinated Debentures. Upon the termination of any such Extension Period and
the payment of all amounts then due on any Interest Payment Date, the Company
may elect to begin a new Extension Period. See "Description of Junior
Subordinated Debentures -- Option to Extend Interest Payment Period" and
"Certain United States Federal Income Tax Consequences -- Interest Income and
Original Issue Discount." The Company has no current intention of exercising its
right to defer payments of interest by extending the interest payment period of
the Junior Subordinated Debentures.
 
     In the event that any date on which Distributions are payable on the
Capital Securities is not a Business Day, then payment of the Distributions
payable on such date will be made on the next succeeding day that is a Business
Day (and without any additional Distributions or other payment in respect of any
such delay), with
 
                                       31
<PAGE>   33
 
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
City, Chicago, Illinois or Cincinnati, Ohio are authorized or required by law or
executive order to remain closed or a day on which the corporate trust office of
the Property Trustee or the Indenture Trustee (as defined herein) is closed for
business.
 
     Distributions on the Capital Securities (other than distributions on a
Redemption Date) will be payable to the holders thereof as they appear on the
register of the Trust on the relevant record dates, which shall be the 1st day
of the month in which the relevant Distribution Date occurs. Distributions
payable on any Capital Securities that are not punctually paid on any
Distribution Date will cease to be payable to the person in whose name such
Capital Securities are registered on the relevant record date, and such
defaulted distribution will instead be payable to the person in whose name such
Capital Securities are registered on the special record date or other specified
date determined in accordance with the Declaration.
 
REDEMPTION
 
     Mandatory Redemption.  Unless a Special Event has occurred, the Capital
Securities will not be redeemable prior to June 15, 2007. Upon the repayment or
redemption of the Junior Subordinated Debentures, whether at Stated Maturity or
upon earlier redemption as provided in the Indenture, the proceeds from such
repayment or redemption shall be applied by the Property Trustee to redeem the
Capital Securities and Common Securities on a pro rata basis, upon not less than
30 nor more than 60 days notice prior to the date fixed for repayment or
redemption. If less than all of the Junior Subordinated Debentures are to be
repaid or redeemed on a Redemption Date, then the proceeds from such repayment
or redemption shall be allocated to the redemption pro rata of the Capital
Securities and the Common Securities.
 
     Special Event Redemption or Distribution of Junior Subordinated
Debentures.  If a Special Event shall occur and be continuing, the Company will
have the right, subject to the receipt of any necessary prior approval of the
Federal Reserve, to either (i) redeem within 90 days following the occurrence of
such Special Event the Junior Subordinated Debentures on the date of redemption
(the "Redemption Date") in whole (but not in part) and thereby cause a mandatory
redemption of the Capital Securities in whole (but not in part) at a redemption
price with respect to the Capital Securities equal to 100% of the liquidation
amount thereof plus accrued and unpaid Distributions thereon or (ii) dissolve
the Trust and, after satisfaction of the claims of creditors of the Trust as
provided by applicable law, cause the Junior Subordinated Debentures to be
distributed to the holders of the Capital Securities in liquidation of the
Trust. Under current United States federal income tax law and interpretations
thereof and assuming, as expected, the Trust is treated as a grantor trust, a
distribution of the Junior Subordinated Debentures would not be a taxable event
to holders of the Capital Securities. Should there be a change in law, a change
in legal interpretation, certain Tax Events or other circumstances, however,
such distribution could be a taxable event to holders of the Capital Securities.
See "Certain United States Federal Income Tax Consequences -- Distribution of
Junior Subordinated Debentures to Holders of Capital Securities."
 
     If the Company does not elect either option described above, the Capital
Securities will remain outstanding until the repayment of the Junior
Subordinated Debentures, whether at maturity or redemption, and in the event a
Tax Event has occurred and is continuing, the Company will be obligated to pay
any additional taxes, duties, assessments and other governmental charges (other
than withholding taxes) to which the Trust has become subject as a result of a
Tax Event. See "Description of Junior Subordinated Debentures".
 
     A "Special Event" means a Tax Event, a Regulatory Capital Event or an
Investment Company Event. A "Tax Event" means the receipt by the Company of an
opinion of counsel, rendered by a law firm having a recognized national tax
practice, to the effect that, as a result of any amendment to, change in or
announced proposed change in the laws (or any regulations thereunder) of the
United States or any political subdivision or taxing authority thereof or
therein, or as a result of any official or administrative pronouncement or
action or judicial decision interpreting or applying such laws or regulations,
which amendment or change is adopted or
 
                                       32
<PAGE>   34
 
which proposed change, pronouncement or decision is announced or which action is
taken on or after the date of original issuance of the Capital Securities, 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 Company on such Junior Subordinated
Debentures is not, or within 90 days of the date of such opinion, will not be,
deductible by the Company, 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. A "Regulatory Capital Event" means that the Company
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 States or any rules, guidelines or
policies of the Federal Reserve or (b) any official administrative pronouncement
or judicial decision for interpreting or applying such laws or regulations which
amendment or change is effective or such pronouncement or decision is announced
on or after the date of original issuance of the Capital Securities, the Capital
Securities do not constitute, or within 90 days of the date thereof, will not
constitute Tier 1 capital (or its then equivalent); provided, however, that the
distribution of the Junior Subordinated Debentures in connection with the
liquidation of the Trust by the Company shall not in and of itself constitute a
Regulatory Capital Event unless such liquidation shall have occurred in
connection with a Tax Event or an Investment Company Event. "Investment Company
Event" means the receipt by the Trust of an opinion of counsel, rendered by a
law firm having a recognized national securities practice, to the effect that,
as a result of the occurrence of a change in law or regulation or a change in
interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority (a "Change in 1940 Act Law"),
the Trust is or will be considered an "investment company" that is required to
be registered under the Investment Company Act of 1940, as amended (the "1940
Act"), which Change in 1940 Act Law becomes effective on or after the date of
original issuance of the Capital Securities.
 
REDEMPTION PROCEDURES
 
     Capital Securities redeemed on each Redemption Date shall be redeemed at
the redemption price in respect of the Junior Subordinated Debentures (the
"Redemption Price") with the applicable proceeds from the contemporaneous
redemption or payment at Stated Maturity of the Junior Subordinated Debentures.
Redemptions of the Capital Securities shall be made and the Redemption Price
shall be payable on each Redemption Date only to the extent that the Trust has
sufficient funds available for the payment of such Redemption Price. See also
"-- Subordination of Common Securities."
 
     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 Capital Securities to be
redeemed at its registered address. 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 available, the Property Trustee
will deposit irrevocably with The Depository Trust Company ("DTC") or its
nominee funds sufficient to pay the applicable Redemption Price for all
securities held in DTC and will give DTC irrevocable instructions and authority
to pay the Redemption Price to the holders of the Capital Securities. See
"-- Book-Entry Issuance." If any Capital Securities are held in definitive form,
the Trust, to the extent funds are available, will irrevocably deposit with the
paying agent for the Capital Securities held in definitive form funds sufficient
to pay the applicable Redemption Price and will give the paying agent
irrevocable instructions and authority to pay the Redemption Price to the
holders thereof upon surrender of their certificates evidencing the Capital
Securities. Notwithstanding the foregoing, Distributions payable on or prior to
the Redemption Date for any Capital Security called for redemption shall be
payable to the holders of such Capital Security on the relevant record dates for
the related Distribution Dates. If notice of redemption shall have been given
and funds deposited as required, then upon the date of such deposit, all rights
of the holders of such Capital Securities so called for redemption will cease,
except the right of the holders of such Capital Securities to receive the
Redemption Price, but without interest on such Redemption Price, and such
Capital Securities will cease to be outstanding. In the event that any date
fixed for redemption of Capital Securities is not a Business Day, then payment
of the Redemption Price payable on such date will be made on the next succeeding
day which is a Business Day (and without any
 
                                       33
<PAGE>   35
 
interest or other payment in respect of any such delay), except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on the date such payment was originally payable. In the event that
payment of the Redemption Price in respect of Capital Securities called for
redemption is improperly withheld or refused and not paid either by the Trust or
by the Company pursuant to the Guarantee as described under "Description of
Guarantee," Distributions on such Capital Securities will continue to accrue at
the then applicable rate, from the Redemption Date originally established by the
Trust for the Capital Securities to the date such Redemption Price is actually
paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.
 
     Subject to applicable law (including, without limitation, United States
federal securities law), the Company 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.
 
     The Trust may not redeem fewer than all of the outstanding Capital
Securities unless all accrued and unpaid distributions have been paid on all
Capital Securities for all quarterly Distribution periods terminating on or
prior to the date of redemption. If less than all of the Capital Securities and
Common Securities issued by the Trust are to be redeemed on a Redemption Date,
then the aggregate amount of such Capital Securities and Common Securities to be
redeemed shall be allocated pro rata among the Capital Securities and the Common
Securities. The particular Capital Securities to be redeemed shall be selected
on a pro rata basis not more than 60 days prior to the Redemption Date by the
Property Trustee from the outstanding Capital Securities not previously called
for redemption, by such method as the Property Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $1,000 or integral multiples of $1,000 in excess thereof) of the
liquidation amount of Capital Securities of denominations larger than $1,000.
The Property Trustee shall promptly notify the trust registrar in writing of the
Capital Securities selected for redemption and, in the case of any Capital
Security selected for partial redemption, the liquidation amount thereof to be
redeemed. For all purposes of the Declaration, unless the context otherwise
requires, all provisions relating to the redemption of Capital Securities shall
relate, in the case of any Capital Security redeemed or to be redeemed only in
part, to the portion of the aggregate liquidation amount of Capital Securities
which has been or is to be redeemed.
 
SUBORDINATION OF COMMON SECURITIES
 
     Payment of Distributions on, and the Redemption Price of, the Capital
Securities and the Common Securities, as applicable, shall be made pro rata
based on the liquidation amount of such Capital Securities and Common
Securities; provided, however, that if on any Distribution Date or Redemption
Date an Indenture Event of Default shall have occurred and be continuing, no
payment of any Distribution on, or Redemption Price of, any of the Common
Securities, and no other payment on account of the redemption, liquidation or
other acquisition of such Common Securities, shall be made unless payment in
full in cash of all accumulated and unpaid Distributions on all of the
outstanding Capital Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all of the outstanding Capital Securities then
called for redemption, shall have been made or provided for, and all funds
available to the Property Trustee shall first be applied to the payment in full
in cash of all Distributions on, or Redemption Price of, the Capital Securities
then due and payable.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
     Pursuant to the Declaration, the Trust shall automatically dissolve on the
first to occur of: (i) June 15, 2057, (ii) certain events of bankruptcy,
dissolution or liquidation of the holder of the Common Securities or the Company
or all or substantially all of their properties; (iii) the distribution of the
Junior Subordinated Debentures to the holders of the Capital Securities or
Common Securities; (iv) the redemption of all of the Capital Securities in
connection with the maturity or redemption of all of the Junior Subordinated
Debentures and (v) the entry by a court of competent jurisdiction of a decree of
judicial dissolution of the Company or the Trust.
 
                                       34
<PAGE>   36
 
     If a dissolution occurs as described in clause (ii), (iv) or (v) above, the
Trust shall be liquidated by the Trustees as expeditiously as the Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to the holders of the
Capital Securities and Common Securities their pro rata interest in the Junior
Subordinated Debentures, unless such distribution is determined by the Property
Trustee not to be practical, in which event such holders will be entitled to
receive out of the assets of the Trust 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
thereof plus accrued and unpaid Distributions thereon to the date of payment
(such amount being the "Liquidation Distribution"). If such Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Liquidation Distribution, then the
amounts payable directly by the Trust on the Trust Securities shall be paid on a
pro rata basis. The holder(s) of the Common Securities will be entitled to
receive distributions upon any such liquidation pro rata with the holders of the
Capital Securities, except that if an Indenture Event of Default has occurred
and is continuing, the Capital Securities shall have a priority over the Common
Securities.
 
     After the liquidation date is fixed for any distribution of Junior
Subordinated Debentures to holders of the Capital Securities (i) the Capital
Securities will no longer be deemed to be outstanding, (ii) DTC or its nominee,
as a record holder of Capital Securities, will receive a registered global
certificate or certificates representing the Junior Subordinated Debentures to
be delivered upon such distribution and (iii) any certificates representing
Capital 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 Capital Securities, and bearing accrued and unpaid
interest in an amount equal to the accrued and unpaid Distributions on such
Capital Securities until such certificates are presented for cancellation
whereupon the Company will issue to such holder, and the Indenture Trustee will
authenticate, a certificate representing such Junior Subordinated Debentures.
 
TRUST ENFORCEMENT EVENTS
 
     An Indenture Event of Default constitutes a Trust Enforcement Event under
the Declaration with respect to the Trust Securities, provided that pursuant to
the Declaration, the holder of the Common Securities will be deemed to have
waived any Trust Enforcement Event with respect to the Common Securities until
all Trust Enforcement Events with respect to the Capital Securities have been
cured, waived or otherwise eliminated. Until such Trust Enforcement Event with
respect to the Capital Securities has 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 with respect to
certain matters under the Declaration, and therefore the Indenture.
 
     Upon the occurrence of a Trust Enforcement Event, the Indenture Trustee (as
defined herein) or the Property Trustee as the holder of the Junior Subordinated
Debentures will have the right under the Indenture to declare the principal of
and interest on the Junior Subordinated Debentures to be immediately due and
payable. Each of the Company and the Trust is required to file annually with the
Property Trustee an officer's certificate as to its compliance with all
conditions and covenants under the Declaration.
 
     If the Property Trustee fails to enforce its rights with respect to the
Junior Subordinated Debentures held by the Trust, any record holder of Capital
Securities may institute legal proceedings directly against the Company to
enforce the Property Trustee's rights under such Junior Subordinated Debentures
without first instituting any legal proceedings against such Property Trustee or
any other person or entity. In addition, if a Trust Enforcement Event has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest, principal or other required payments on the Junior
Subordinated Debentures issued to the Trust on the date such interest, principal
or other payment is otherwise payable, then a record holder of Capital
Securities may, on or after the respective due dates specified in the Junior
Subordinated Debentures, institute a proceeding directly against the Company for
enforcement of payment on Junior Subordinated Debentures having a principal
amount equal to the aggregate liquidation amount of the Capital Securities held
by such holder. In connection with such Direct Action, the Company will be
subrogated to the rights of such
 
                                       35
<PAGE>   37
 
record holder of Capital Securities to the extent of any payment made by the
Company to such record holder of Capital Securities.
 
VOTING RIGHTS; AMENDMENT OF THE DECLARATION
 
     Except as provided below and under "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.
 
     So long as any Junior Subordinated 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 Indenture Trustee or
executing any trust or power conferred on the Property Trustee with respect to
such Junior Subordinated Debentures, (ii) waive any past default that is
waivable under the Indenture, (iii) exercise any right to rescind or annul a
declaration that the principal of all the Junior Subordinated Debentures shall
be due and payable or (iv) consent to any amendment, modification or termination
of the Indenture or such Junior Subordinated Debentures, where such consent
shall be required, without, in each case, obtaining the prior approval of the
holders of a majority in aggregate liquidation amount of all outstanding 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 consent of each holder of Capital Securities. The Trustees shall not
revoke any action previously authorized or approved by a vote of the holders of
the Capital Securities except pursuant to a subsequent vote of the holders of
the Capital Securities. The Property Trustee shall notify each holder of record
of the Capital Securities of any notice of default which it receives with
respect to the Junior Subordinated Debentures. In addition to obtaining the
foregoing approvals of the holders of the Capital Securities, prior to taking
any of the foregoing actions, the Trustees shall receive an opinion of counsel
experienced in such matters to the effect that the Trust will not be classified
as other than a grantor trust for United States federal income tax purposes on
account of such action.
 
     The Declaration may be amended from time to time by the Company and a
majority of the Regular Trustees (and in certain circumstances the Property
Trustee and the Delaware Trustee), without the consent of the holders of the
Capital 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 that shall not be inconsistent with the other provisions
of the Declaration, or (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 as a grantor trust for United States federal income tax purposes
at all times that any Capital Securities and Common Securities are outstanding
or to ensure that the Trust will not be required to register as an "investment
company" under the Investment Company Act, provided, however, that such action
shall not adversely affect in any material respect the interests of any holder
of Capital Securities or Common Securities, and any amendments of the
Declaration shall become effective when notice thereof is given to the holders
of Capital Securities and Common Securities. The Declaration may be amended by
the Company and a majority of the Regular Trustees with (i) the consent of
holders representing not less than a majority (based upon liquidation amounts)
of the outstanding Capital Securities and Common Securities and (ii) receipt by
the Regular Trustees of an opinion of counsel to the effect that such amendment
or the exercise of any power granted to the Regular 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, further that
without the consent of each holder of Capital Securities and Common Securities
affected thereby, the Declaration may not be amended to (i) change the amount or
timing of any Distribution on the Capital Securities and Common Securities or
otherwise adversely affect the amount of any Distribution required to be made in
respect of the Capital Securities and Common Securities as of a specified date
or (ii) restrict the right of a holder of Capital Securities or Common
Securities to institute suit for the enforcement of any such payment on or after
such date.
 
     Any required approval of holders of Capital Securities may be given at a
meeting of holders of Capital Securities convened for such purpose or pursuant
to written consent. The Regular 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
 
                                       36
<PAGE>   38
 
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 its Capital Securities in accordance with the
Declaration.
 
     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 Company, the Trustees or any affiliate of the
Company or any Trustees, shall, for purposes of such vote or consent, be treated
as if they were not outstanding.
 
EXPENSES AND TAXES
 
     In the Indenture, the Company, as borrower, has agreed to pay all debts and
other obligations (other than with respect to the Capital Securities) and all
costs and expenses of the Trust (including costs and expenses relating to the
organization of the Trust, the fees and expenses of the Trustees and the costs
and expenses relating to the operation of the Trust) and to pay any and all
taxes and all costs and expenses with respect thereto (other than United States
withholding taxes) to which the Trust might become subject. The foregoing
obligations of the Company under the Indenture are for the benefit of, and shall
be enforceable by, any person to whom any such debts, obligations, costs,
expenses and taxes are owed (a "Creditor") whether or not such Creditor has
received notice thereof. Any such Creditor may enforce such obligations of the
Company directly against the Company, and the Company has irrevocably waived any
right or remedy to require that any such Creditor take any action against the
Trust or any other person before proceeding against the Company. The Company has
also agreed in the Indenture to execute such additional agreements as may be
necessary or desirable to give full effect to the foregoing.
 
REGISTRAR AND TRANSFER AGENT
 
     The Property Trustee will act as registrar and transfer agent for the
Capital Securities.
 
     Registration of transfers of 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 (i) to register or cause to be
registered the transfer or exchange of the Capital Securities during a period
beginning at the opening of business 15 days before the day of the mailing of
the relevant notice of redemption and ending at the close of business on the day
of mailing of such notice of redemption or (ii) to register or cause to be
registered the transfer or exchange of any Capital Securities so selected for
redemption, except in the case of any Capital Securities being redeemed in part,
any portion thereof not to be redeemed.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
     The Property Trustee, other than during the occurrence and continuance of a
Trust Enforcement Event, undertakes to perform only such duties as are
specifically set forth in the Declaration and, after such Trust Enforcement
Event, 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 Capital
Securities unless it is offered reasonable indemnity against the costs, expenses
and liabilities that might be incurred thereby. If no Trust Enforcement Event
has occurred and is continuing and the Property Trustee is required to decide
between alternative causes 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 Capital Securities are entitled
under the Declaration to vote, then the Property Trustee may, but shall be under
no duty to, take such action as is directed by the Company and, if not so
directed, shall take such action as it deems advisable and in the best interests
of the holders of the Capital Securities and the Common Securities and will have
no liability except for its own bad faith, negligence or willful misconduct.
 
                                       37
<PAGE>   39
 
PAYMENT AND PAYING AGENCY
 
     Payments in respect of the Global Certificates shall be made to DTC, which
shall credit the relevant accounts at DTC on the applicable Distribution Dates
or, if the Capital Securities are held in definitive form, such payments 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 Property Trustee. The
paying agent (the "Paying Agent") shall initially be the New York affiliate of
The First National Bank of Chicago and any co-paying agent chosen by the
Property Trustee and acceptable to the Regular Trustees and the Company. The
Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Property Trustee and the Company. In the event that the Property
Trustee shall no longer be the Paying Agent, the Regular Trustees shall appoint
a successor (which shall be a bank or trust company acceptable to the Regular
Trustees and the Company) to act as Paying Agent.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE TRUST
 
     The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described below. The Trust may, at the request of the Company, with the consent
of the Regular Trustees and without the consent of the holders of the Capital
Securities, merge with or into, consolidate, amalgamate, be replaced by or
convey, transfer or lease its properties and assets substantially as an entirety
to a trust organized as such under the laws of any State; provided that (i) such
successor entity either (a) expressly assumes all of the obligations of the
Trust with respect to the 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
Company expressly appoints a trustee of such successor entity possessing the
same powers and duties as the Property Trustee as the holder of the Junior
Subordinated Debentures, (iii) 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, (iv) such merger, 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, (v)
such successor entity has a purpose identical to that of the Trust, (vi) prior
to such merger, consolidation, amalgamation, replacement, conveyance, transfer,
or lease, the Company has received an opinion from 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 of the
Capital Securities (including any Successor Securities) in any material respect
and (b) following such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, (1) neither the Trust nor such successor entity
will be required to register as an investment company under the Investment
Company Act and (2) the Trust or the successor entity will continue to be
classified as a grantor trust for United States federal income tax purposes,
(vii) the Company 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, (viii) such successor entity expressly assumes all of the
obligations of the Trust with respect to the Trustees and (ix) the Successor
Securities are listed, or any Successor Securities will be listed upon
notification of issuance on any national securities exchange or other
organization on which the Capital Securities are then listed. Notwithstanding
the foregoing, the Trust shall not, except with the consent of holders of 100%
in aggregate liquidation amount of the Capital Securities, consolidate,
amalgamate, merge with or into, be replaced by or convey, transfer or lease its
properties and assets substantially as an entirety to any other entity or permit
any other entity to consolidate, amalgamate, merge with or into, or replace it
if such consolidation, amalgamation, merger, replacement, conveyance, transfer
or lease would cause the Trust or the successor entity to be classified as other
than a grantor trust for United States federal income tax purposes.

MERGER OR CONSOLIDATION OF TRUSTEES
 
     Any corporation into which the Property Trustee, the Delaware Trustee or
any Regular Trustee that is not a natural person may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which such Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of such Trustee, shall be the successor of such Trustee under the Declaration,
provided such corporation shall be otherwise qualified and eligible.
 
MISCELLANEOUS
 
     The Regular 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 other than a grantor trust for United States federal income
tax purposes and so that the Junior Subordinated Debentures will be treated as
indebtedness of the Company for United States federal income tax purposes. In
this connection, the Company and the Regular Trustees are authorized to take any
action, not inconsistent with applicable law, the Certificate of Trust or the
Declaration, that the Company and the Regular 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
Capital Securities.
 
     The Trust may not borrow money nor issue debt nor mortgage or pledge any of
its assets.
 
                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES
 
     The Old Junior Subordinated Debentures were issued and the New Junior
Subordinated Debentures are to be issued under a Junior Subordinated Indenture
(the "Indenture"), between the Company and The First National Bank of Chicago,
as trustee (the "Indenture Trustee"). This summary of certain terms and
provisions of the Junior Subordinated Debentures and the Indenture does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, the Indenture.
 
GENERAL
 
     Concurrently with the issuance of the Old Capital Securities, the Trust
invested the proceeds thereof, together with the consideration paid by the
Company for the Common Securities, in the Old Junior Subordinated Debentures
issued by the Company. Pursuant to the Exchange Offer, the Company will exchange
the Old Junior Subordinated Debentures for the New Junior Subordinated
Debentures as soon as practicable after the Expiration Date. No Old Junior
Subordinated Debentures will remain outstanding after such exchange. The
following is a description of the Junior Subordinated Debentures.
 
     The Junior Subordinated Debentures will be in the principal amount equal to
the aggregate liquidation amount of the Capital Securities plus the Company's
concurrent investment in the Common Securities. The Junior Subordinated
Debentures will bear interest at a variable annual rate of LIBOR plus 0.765% of
the principal amount thereof, payable quarterly in arrears on the fifteenth day
of March, June, September and December of each year (each, an "Interest Payment
Date"), commencing September 15, 1997, to the person in whose name each Junior
Subordinated Debenture is registered, subject to certain exceptions, at the
close of business on the 1st day of the month in which the relevant Interest
Payment Date occurs. 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 Capital
Securities and the Common Securities. The amount of interest payable for any
period will be computed on the actual number of days elapsed in a year of twelve
30-day months. In the event that any date on which interest is payable on the
Junior Subordinated Debentures is not a Business Day, then payment of the
interest payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay), except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and
 
                                       39
<PAGE>   41
 
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 variable rate per annum of LIBOR plus 0.765% thereof, compounded quarterly.
The term "interest" as used herein shall include quarterly interest payments and
interest on quarterly interest payments not paid on the applicable Interest
Payment Date, as applicable.
 
     The Junior Subordinated Debentures will mature on June 15, 2027 (the
"Stated Maturity").
 
     The Junior Subordinated Debentures are unsecured and rank junior and
subordinate in right of payment to all Indebtedness (as defined below) of the
Company. The Indenture does not limit the incurrence or issuance of other
secured or unsecured debt of the Company, whether under the Indenture or any
existing or other indenture that the Company may enter into in the future or
otherwise. See "-- Subordination."
 
     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 Company that may adversely affect holders of the
Junior Subordinated Debentures.
 
INTEREST
 
     The First National Bank of Chicago, as Calculation Agent (the "Calculation
Agent"), will calculate the interest rate for each quarterly interest period
based on LIBOR determined as of two London Business Days (defined as any day,
other than a Saturday or Sunday, on which banks are open for business in London)
prior to the first day of such interest period (each, a "Determination Date").
"LIBOR" means, with respect to a quarterly interest period relating to an
Interest Payment Date (in the following order of priority):
 
          (i) the rate (expressed as a percentage per annum) for Eurodollar
     deposits having a three-month maturity that appears on Telerate Page 3750
     as of 11:00 a.m. (London time) on the related Determination Date;
 
          (ii) if such rate does not appear on Telerate Page 3750 as of 11:00
     a.m. (London time) on the related Determination Date, LIBOR will be the
     arithmetic mean (if necessary rounded upwards to the nearest whole multiple
     of .00001%) of the rates (expressed as percentages per annum) for
     Eurodollar deposits having a three-month maturity that appear on Reuters
     Monitor Money Rates Page LIBO ("Reuters Page LIBO") as of 11:00 a.m.
     (London time) on such Determination Date;
 
          (iii) if such rate does not appear on Reuters Page LIBO as of 11:00
     a.m. (London time) on the related Determination Date, the Calculation Agent
     will request the principal London offices of four leading banks in the
     London interbank market to provide such banks' offered quotations
     (expressed as percentages per annum) to prime banks in the London interbank
     market for Eurodollar deposits having a three-month maturity as of 11:00
     a.m. (London time) on such Determination Date. If at least two quotations
     are provided, LIBOR will be the arithmetic mean (if necessary rounded
     upwards to the nearest whole multiple of .00001%) of such quotations;
 
          (iv) if fewer than two such quotations are provided as requested in
     clause (iii) above, the Calculation Agent will request four major New York
     City banks to provide such banks' offered quotations (expressed as
     percentages per annum) to leading European banks for loans in Eurodollars
     as of 11:00 a.m. (London time) on such Determination Date. If at lease two
     such quotations are provided, LIBOR will be the arithmetic mean (if
     necessary rounded upwards to the nearest whole multiple of .00001%) of such
     quotations; and
 
          (v) if fewer than two such quotations are provided as requested in
     clause (iv) above, LIBOR will be LIBOR as determined on the immediately
     preceding Determination Date.
 
     If the rate for Eurodollar deposits having a three-month maturity that
initially appears on Telerate Page 3750 or Reuters Page LIBO, as the case may
be, as of 11:00 a.m. (London time) on the related Determination Date is
superseded on Telerate Page 3750 or Reuters Page LIBO, as the case may be, by a
corrected rate before 12:00 noon (London time) on such Determination Date, the
corrected rate as so substituted on the applicable page will be the applicable
LIBOR for such Determination Date.
 
                                       40
<PAGE>   42
 
     Absent manifest error, the Calculation Agent's determination of LIBOR and
its calculation of the applicable dividend rate for each interest period will be
final and binding. Investors may obtain the interest rates for the current and
preceding interest period by writing Investor Relations at the Calculation Agent
at The First National Bank of Chicago, One First National Plaza, Suite 0134,
Chicago, Illinois 60670, or by calling (800) 524-9472 or (312) 407-4660.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
     So long as no Indenture Event of Default has occurred and is continuing,
the Company has the right under the Indenture to defer the payment of interest
at any time or from time to time for a period not exceeding 20 consecutive
quarterly periods with respect to each Extension Period, provided that no
Extension Period may extend beyond the Stated Maturity of the Junior
Subordinated Debentures. At the end of such Extension Period, the Company must
pay all interest then accrued and unpaid (together with interest thereon at a
variable annual rate of LIBOR plus 0.765%, compounded quarterly, to the extent
permitted by applicable law). During an Extension Period, interest will continue
to accrue and holders of Junior Subordinated Debentures (or holders of Capital
Securities while the Capital Securities are outstanding) will be required to
accrue interest income for United States federal income tax purposes. See
"Certain United States Federal Income Tax Consequences -- Interest Income and
Original Issue Discount."
 
     During any such Extension Period, the Company may not, and may not permit
any subsidiary of the Company to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock or (ii) make any payment of
principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities of the Company that rank pari passu with or junior in interest
to the Junior Subordinated Debentures or make any guarantee payments with
respect to any guarantee by the Company of the debt securities of any subsidiary
of the Company if such guarantee ranks pari passu or junior in interest to the
Junior Subordinated Debentures (other than (a) repurchases, redemptions or other
acquisitions of shares of capital stock of the Company in connection with any
employment contract, benefit plan or other similar arrangement with or for the
benefit of any one or more employees, officers, directors or consultants or in
connection with a dividend reinvestment or stockholder stock purchase plan, (b)
as a result of an exchange or conversion of any class or series of the Company's
capital stock (or any capital stock of a subsidiary of the Company) for any
class or series of the Company's capital stock or of any class or series of the
Company's indebtedness for any class or series of the Company's capital stock,
(c) the purchase of fractional interests in shares of the Company's capital
stock pursuant to the conversion or exchange provisions of such capital stock or
the security being converted or exchanged, (d) any declaration of a dividend in
connection with the adoption of any stockholder's rights plan, or the issuance
of rights, stock or other property under any stockholder's rights plan, or the
redemption or repurchase of rights pursuant thereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock). Prior to the termination of any such Extension Period,
the Company may further extend the Extension Period, provided that no Extension
Period may exceed 20 consecutive quarterly periods or extend beyond the Stated
Maturity of the Junior Subordinated Debentures. Upon the termination of any such
Extension Period and the payment of all amounts then due on any Interest Payment
Date, the Company may elect to begin a new Extension Period subject to the above
requirements. No interest shall be due and payable during an Extension Period,
except at the end thereof. The Company must give the Property Trustee, the
Regular Trustees and the Indenture Trustee notice of its election of such
Extension Period not less than one Business Day prior to such record date. The
Property Trustee shall give notice of the Company's election to begin a new
Extension Period to the holders of the Capital Securities.
 
REDEMPTION
 
     The Junior Subordinated Debentures are not redeemable prior to June 15,
2007 unless a Special Event has occurred. The Junior Subordinated Debentures are
redeemable prior to maturity at the option of the Company, subject to the
receipt of any necessary prior approval of the Federal Reserve, on or after June
15,
 
                                       41
<PAGE>   43
 
2007, in whole or in part, at any time at a redemption price equal to 100% of
the principal amount of the Junior Subordinated Debentures to be redeemed plus
any accrued but unpaid interest (including any Additional Interest), if any, to
the date of redemption.
 
     The Junior Subordinated Debentures are also redeemable at any time in whole
(but not in part) at a redemption price (the "Special Event Prepayment Price")
equal to 100% of the principal amount of such Junior Subordinated Debentures
plus accrued but unpaid interest thereon to the date of prepayment.
 
     If the Junior Subordinated Debentures are redeemed, the Trust must redeem
the Capital Securities having an aggregate liquidation amount equal to the
aggregate principal amount of Junior Subordinated Debentures so redeemed. See
"Description of Capital Securities -- Redemption -- Mandatory Redemption."
 
     Notice of any redemption will be mailed at least 30 days (provided that the
Indenture Trustee shall itself have received notice not less than 45 days prior
to the redemption date) but not more than 60 days before the redemption date to
each Holder of Junior Subordinated Debentures to be redeemed at its registered
address. Unless the Company defaults in payment of the redemption price, on and
after the redemption date interest ceases to accrue on such Junior Subordinated
Debentures or portions thereof called for redemption.
 
CERTAIN COVENANTS OF THE COMPANY
 
     The Company has covenanted in the Indenture that if and so long as the
Trust is the holder of all Junior Subordinated Debentures, the Company, as
borrower, will pay to the Trust all fees and expenses related to the Trust and
the offering of the Capital Securities and will pay, directly or indirectly, all
ongoing costs, expenses and liabilities of the Trust (including any taxes,
duties, assessments or governmental charges of whatever nature (other than
withholding taxes) imposed by the United States or any domestic taxing authority
upon the Trust but excluding obligations under the Capital Securities).
 
     The Company has also covenanted that it will not, and will not permit any
subsidiary of the Company to, (i) declare or pay any dividends or distributions
on, or redeem, purchase, acquire, or make a liquidation payment with respect to,
any of the Company's capital stock or (ii) make any payment of principal,
interest or premium, if any, on or repay or repurchase or redeem any debt
securities of the Company that rank pari passu with or junior in interest to the
Junior Subordinated Debentures or make any guarantee payments with respect to
any guarantee by the Company of the debt securities of any subsidiary of the
Company if such guarantee ranks pari passu with or junior in interest to the
Junior Subordinated Debentures (other than (a) repurchases, redemptions or other
acquisitions of shares of capital stock of the Company in connection with any
employment contract, benefit plan or other similar arrangement with or for the
benefit of any one or more employees, officers, directors or consultants or in
connection with a dividend reinvestment or stockholder stock purchase plan, (b)
as a result of an exchange or conversion of any class or series of the Company's
capital stock (or any capital stock of a subsidiary of the Company) for any
class or series of the Company's capital stock or of any class or series of the
Company's indebtedness for any class or series of the Company's capital stock,
(c) the purchase of fractional interests in shares of the Company's capital
stock pursuant to the conversion or exchange provisions of such capital stock or
the security being converted or exchanged, (d) any declaration of a dividend in
connection with the adoption of any stockholder's rights plan, or the issuance
of rights, stock or other property under any stockholder's rights plan, or the
redemption or repurchase of rights pursuant thereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock) if at such time (x) there shall have occurred any event
of which the Company has actual knowledge that (I) with the giving of notice or
the lapse of time, or both, would constitute an Indenture Event of Default with
respect to Junior Subordinated Debentures and (II) in respect of which the
Company shall not have taken reasonable steps to cure, (y) the Company shall be
in default with respect to its payment of any obligations under the Guarantee or
(z) the Company shall have given notice of its election of an Extension Period
as provided in the Indenture and shall not have rescinded such notice, or such
Extension Period, or any extension thereof, shall be continuing.

SUBORDINATION
 
     In the Indenture, the Company has covenanted and agreed that any Junior
Subordinated Debentures issued thereunder will be subordinated and junior in
right of payment to all 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 Company, the holders of Indebtedness will first be
entitled to receive payment in full of principal of and premium, if any, and
interest, if any, on such Indebtedness before the holders of Junior Subordinated
Debentures or the Property Trustee on behalf of the holders of Capital
Securities will be entitled to receive or retain any payment in respect of the
principal of and premium, if any, or interest, if any, on the Junior
Subordinated Debentures; provided, however, that holders of Indebtedness shall
not be entitled to receive payment of any such amounts to the extent that such
holders would be required by the subordination provisions of such Indebtedness
to pay such amounts over to the obligees on trade accounts payable or other
liabilities arising in the ordinary course of the Company's business.
 
     In the event of the acceleration of the maturity of any Junior Subordinated
Debentures, the holders of all Indebtedness outstanding at the time of such
acceleration will first be entitled to receive payment in full of all amounts
then due thereon (including any amounts due upon acceleration) before the
holders of Junior Subordinated Debentures will be entitled to receive or retain
any payment in respect of the principal of or premium, if any, or interest, if
any, on the Junior Subordinated Debentures; provided, however, that holders of
Indebtedness shall not be entitled to receive payment of any such amounts to the
extent that such holders would be required by the subordination provisions of
such Indebtedness to pay such amounts over to the obligees on trade accounts
payable or other liabilities arising in the ordinary course of the Company's
business.
 
     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
Indebtedness, or an event of default with respect to any Indebtedness resulting
in the acceleration of the maturity thereof, or if any judicial proceeding shall
be pending with respect to any such default.
 
     "Indebtedness" means with respect to any person, whether recourse is to all
or a portion of the assets of such person and whether or not contingent, (i)
every obligation of such person for money borrowed; (ii) every obligation of
such person evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses; (iii) every reimbursement obligation of such person with
respect to letters of credit, bankers' acceptances or similar facilities issued
for the account of such person; (iv) every obligation of such person issued or
assumed as the deferred purchase price of property or services (but excluding
trade accounts payable or accrued liabilities arising in the ordinary course of
business); (v) every capital lease obligation of such person; (vi) every
obligation of such person for claims (as defined in Section 101(4) of the United
States Bankruptcy Code of 1978, as amended) in respect of derivative products
such as interest and foreign exchange rate contracts, commodity contracts and
similar arrangements; and (vii) every obligation of the type referred to in
clauses (i) through (vi) of another person and all dividends of another person
the payment of which, in either case, such person has guaranteed or is
responsible or liable, directly or indirectly, as obligor or otherwise; provided
that "Indebtedness" shall not include (i) any obligations which, by their terms,
are expressly stated to rank pari passu in right of payment with, or to not be
superior in right of payment to, the Junior Subordinated Debentures, (ii) any
Indebtedness of the Company which when incurred and without respect to any
election under Section 1111(b) of the United States Bankruptcy Code of 1978, as
amended, was without recourse to the Company, (iii) any Indebtedness of the
Company to any of its subsidiaries, (iv) Indebtedness to any employee of the
Company or (v) any indebtedness in respect of debt securities issued to any
trust, or a trustee of such trust, partnership or other entity affiliated with
the Company that is a financing entity of the Company in connection with the
issuance of such financing entity of securities that are similar to the Capital
Securities.
 
     The Indenture places no limitation on the amount of additional Indebtedness
that may be incurred by the Company or any indebtedness or other liabilities
that may be incurred by the Company's subsidiaries. As of
 
                                       43
<PAGE>   45
 
June 30, 1997, Indebtedness of the Company aggregated approximately $152
million, and the Company's consolidated subsidiaries had indebtedness and other
liabilities of approximately $9.9 billion to which the Junior Subordinated
Debentures would be effectively subordinated.
 
INDENTURE EVENTS OF DEFAULT
 
     The Indenture provides that any one or more of the following described
events with respect to the Junior Subordinated Debentures that has occurred and
is continuing constitutes an "Indenture Event of Default" with respect to the
Junior Subordinated Debentures:
 
          (i) failure for 30 days to pay any interest on the Junior Subordinated
     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 on the Junior Subordinated
     Debentures when due whether at maturity, upon redemption by declaration 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 Company from the Indenture Trustee or the holders of at least 25% in
     aggregate outstanding principal amount of outstanding Junior Subordinated
     Debentures; or
 
          (iv) certain events in bankruptcy, insolvency or reorganization of the
     Company.
 
     The holders of a majority in aggregate outstanding principal amount of
Junior Subordinated Debentures have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Indenture
Trustee. The Indenture Trustee or the holders of not less than 25% in aggregate
outstanding principal amount of Junior Subordinated Debentures may declare the
principal due and payable immediately upon an Indenture Event of Default, and,
should the Indenture Trustee or such holders of such Junior Subordinated
Debentures fail to make such declaration, the holders of at least 25% in
aggregate liquidation amount of the Capital Securities shall have such right.
The holders of a majority in aggregate outstanding principal amount of Junior
Subordinated Debentures may annul such declaration and waive the default if the
default (other than the non-payment of the principal of 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 Indenture Trustee,
and should the holders of such Junior Subordinated Debentures fail to annul such
declaration and waive such default, the holders of a majority in aggregate
liquidation amount of the Capital Securities shall have such right.
 
     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 or interest (unless such default has been cured and
a sum sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Indenture 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 Debentures, and should the holders of such Junior
Subordinated Debentures fail to waive such default, the holders of a majority in
aggregate liquidation amount of the Capital Securities shall have such right.
The Company is required to file annually with the Indenture Trustee a
certificate as to whether or not the Company is in compliance with all the
conditions and covenants applicable to it under the Indenture.
 
     In case an Indenture Event of Default shall occur and be continuing, the
Property Trustee will have the right to declare the principal of and the
interest on such Junior Subordinated Debentures and any other amounts payable
under the Indenture, to be forthwith due and payable and to enforce its other
rights as a creditor with respect to such Junior Subordinated Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF CAPITAL SECURITIES
 
     If an Indenture Event of Default has occurred and is continuing and such
event is attributable to the failure of the Company to pay interest or principal
on the Junior Subordinated Debentures on the date such
 
                                       44
<PAGE>   46
 
interest or principal is otherwise payable, a holder of Capital Securities may
institute a Direct Action for payment. The Company 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
payment made to such holder of Capital Securities by the Company in connection
with a Direct Action, the Company shall remain obligated to pay the principal of
or interest on the Junior Subordinated Debentures held by the Trust or the
Property Trustee and the Company 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 Company to such holder in any Direct
Action. The holders of Capital Securities will not be able to exercise directly
any other remedy available to the holders of the Junior Subordinated Debentures.
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
     The Indenture provides that the Company shall not consolidate with or merge
into any other Person or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, unless (i) in case the Company
consolidates with or merges into another Person or conveys, transfers or leases
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
Company's obligations on the Junior Subordinated Debentures issued under the
Indenture; (ii) immediately after giving effect thereto, no Indenture Event of
Default, and no event which, after notice or lapse of time or both, would become
an Indenture Event of Default, shall have happened and be continuing; (iii) if
at the time any Capital Securities are outstanding, such transaction is
permitted under the Declaration and Guarantee and does not give rise to any
breach or violation of the Declaration or Guarantee, (iv) any such lease shall
provide that it will remain in effect so long as any Junior Subordinated
Debentures are outstanding, and (v) certain other conditions as prescribed in
the Indenture are met.
 
MODIFICATION OF INDENTURE
 
     From time to time the Company and the Indenture Trustee may, without the
consent of the holders of the 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 Company and the Indenture Trustee, with the consent of the
holders of not less than a majority in principal amount of outstanding Junior
Subordinated Debentures affected, to modify the Indenture in a manner affecting
the rights of the holders of such Junior Subordinated Debentures; provided that
no such modification may, without the consent of the holder of each outstanding
Junior Subordinated Debentures so affected, (i) change the stated maturity of
Junior Subordinated Debentures, or reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon (except such
extension as is contemplated hereby) 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, provided that, so long as any
Capital Securities remain outstanding, no such modification may be made that
adversely affects the holders of such Capital Securities in any material
respect, and no termination of the Indenture may occur, and no waiver of any
Indenture Event of Default or compliance with any covenant under the Indenture
may be effective, without the prior consent of the holders of at least a
majority of the aggregate liquidation amount of the outstanding Capital
Securities unless and until the principal of the Junior Subordinated Debentures
and all accrued and unpaid interest thereon have been paid in full and certain
other conditions are satisfied.
 
DEFEASANCE AND DISCHARGE
 
     The Indenture provides that the Company, at the Company's option: (a) will
be discharged from any and all obligations in respect of the Junior Subordinated
Debentures (except for certain obligations to register the transfer or exchange
of Junior Subordinated Debentures, replace stolen, lost or mutilated Junior
Subordinated Debentures, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with
 
                                       45
<PAGE>   47
 
certain restrictive covenants of the Indenture (including that described in the
second paragraph under "Certain Covenants of the Company"), in each case if the
Company deposits, in trust with the Indenture Trustee or a defeasance agent,
money or U.S. Government Obligations which through the payment of interest
thereon and principal thereof in accordance with their terms will provide money,
in an amount sufficient to pay all the principal of, and interest and premium,
if any, on the Junior Subordinated Debentures on the dates such payments are due
in accordance with the terms of such Junior Subordinated Debentures. To exercise
any such option, the Company is required to deliver to the Indenture Trustee or
a defeasance agent, if any, an opinion of counsel to the effect that the deposit
and related defeasance would not cause the holders of the Junior Subordinated
Debentures to recognize income, gain or loss for United States federal income
tax purposes and, in the case of a discharge pursuant to clause (a), such
opinion shall be accompanied by a private letter ruling to such effect received
by the Company from the United States Internal Revenue Service or revenue ruling
pertaining to a comparable form of transaction to such effect published by the
United States Internal Revenue Service.
 
DISTRIBUTIONS OF JUNIOR SUBORDINATED DEBENTURES; BOOK-ENTRY ISSUANCE
 
     Under certain circumstances involving the termination of the Trust, Junior
Subordinated Debentures may be distributed to the holders of the Capital
Securities in liquidation of the Trust after satisfaction of liabilities to
creditors of the Trust as provided by applicable law. If distributed to holders
of Capital Securities in liquidation, the Junior Subordinated Debentures will
initially be issued in the form of global securities. DTC, or any successor
depositary, will act as depositary for such global securities. It is anticipated
that the depositary arrangements for such global securities would be
substantially identical to those in effect for the Capital Securities. For a
description of such procedures, see "Book-Entry Issuance."
 
     There can be no assurance as to the market price of any Junior Subordinated
Debentures that may be distributed to the holders of Capital Securities.
 
PAYMENT AND PAYING AGENTS
 
     The Company initially will act as Paying Agent with respect to the Junior
Subordinated Debentures except that, if the Junior Subordinated Debentures are
distributed to the holders of the Capital Securities in liquidation of such
holders' interests in the Trust, the Indenture Trustee will act as the Paying
Agent. The Company at any time may designate additional Paying Agents or rescind
the designation of any Paying Agent or approve a change in the office through
which any Paying Agent acts, except that the Company will be required to
maintain a Paying Agent at the place of payment.
 
     Any moneys deposited with the Indenture Trustee or any Paying Agent, or
then held by the Company in trust, for the payment of the principal of and
premium, if any, or interest on any Junior Subordinated Debentures 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 Company, be repaid to
the Company and the holder of such Junior Subordinated Debentures shall
thereafter look, as a general unsecured creditor, only to the Company for
payment thereof.
 
GOVERNING LAW
 
     The Indenture and the Junior Subordinated Debentures will be governed by
and construed in accordance with the laws of the State of New York.
 
INFORMATION CONCERNING THE INDENTURE TRUSTEE
 
     The Indenture 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 Indenture 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 Indenture Trustee is not required to
 
                                       46
<PAGE>   48
 
expend or risk its own funds or otherwise incur personal financial liability in
the performance of its duties if the Indenture 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 Company concurrently
with the issuance by the Trust of the Old Capital Securities for the benefit of
the holders from time to time of the Capital Securities. As soon as practicable
after the Expiration Date, the Old Guarantee will be exchanged by the Company
for the New Guarantee. The First National Bank of Chicago will act as guarantee
trustee ("Guarantee Trustee") under the New Guarantee. This summary of certain
provisions of the Guarantee 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, including the definitions therein of certain terms. The Guarantee
Trustee will hold the New Guarantee for the benefit of the holders of the
Capital Securities.
 
GENERAL
 
     The Company has irrevocably and unconditionally 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"), will be 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 available therefor at
the time, (ii) the redemption price with respect to any Capital Securities
called for redemption, to the extent that the Trust has funds on hand available
therefor at such time, or (iii) upon a voluntary or involuntary dissolution,
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 accrued and unpaid
Distributions to the date of payment and (b) the amount of assets of the Trust
remaining available for distribution to holders of Capital Securities. The
Company's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Company to the holders of the applicable
Capital Securities or by causing the Trust to pay such amounts to such holders.
 
     The Guarantee is an irrevocable guarantee on a subordinated basis of the
Trust's obligations under the Capital Securities, but will apply only to the
extent that the Trust has funds on hand available to make such payments, and is
not a guarantee of collection.
 
     If the Company does not make interest payments on the Junior Subordinated
Debentures held by the Trust, the Trust will not be able to pay Distributions on
the Capital Securities and will not have funds legally available therefor. The
Guarantee will rank subordinate and junior in right of payment to all general
liabilities of the Company. See "-- Status of the Guarantee." The Guarantee does
not limit the incurrence or issuance of other secured or unsecured debt of the
Company, whether under the Indenture or any existing or other indenture that the
Company may enter into in the future or otherwise.
 
     The Company has, through the Guarantee, the Junior Subordinated Debentures
and the Indenture, taken together, fully 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 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 --
General."
 
STATUS OF THE GUARANTEE
 
     The Guarantee constitutes an unsecured obligation of the Company and ranks
subordinate and junior in right of payment to Indebtedness of the Company. The
Guarantee does not place a limitation on the amount of additional Indebtedness
that may be incurred by the Company.
 
                                       47
<PAGE>   49
 
     The Guarantee constitutes a guarantee of payment and not of collection
(i.e., the guaranteed party may institute a legal proceeding directly against
the Guarantor to enforce its rights under the Guarantee without first
instituting a legal proceeding against any other person or entity). 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 of the Junior
Subordinated Debentures to the holders of the Capital Securities in exchange for
all of the Capital Securities.
 
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 not less than a majority of the aggregate liquidation amount of the
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 shall bind the successors, assigns, receivers, trustees and
representatives of the Company and shall inure to the benefit of the holders of
the Capital Securities then outstanding.
 
EVENTS OF DEFAULT
 
     An event of default under the Guarantee will occur upon the failure of the
Company to perform any of its payment or other obligations thereunder. The
holders of not less than a majority in aggregate liquidation amount of the
Capital Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the 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 Company 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 Company, as guarantor, is required to file annually with the Guarantee
Trustee a certificate as to whether or not the Company is in compliance with all
the conditions and covenants applicable to it under the Guarantee.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, other than during the occurrence and continuance of
a default by the Company in performance of the Guarantee, undertakes to perform
only such duties as are specifically set forth in each 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 conduct of his or her own
affairs. Subject to this provision, the Guarantee Trustee is under no obligation
to exercise any of the powers vested in it by the Guarantee at the request of
any holder of any Capital Security unless it is offered reasonable indemnity
against the costs, expenses and liabilities that might be incurred thereby.
 
TERMINATION OF THE GUARANTEE
 
     The Guarantee will terminate and be of no further force and effect upon
full payment of the redemption price of all of the Capital Securities, upon full
payment of the amounts payable upon liquidation of the Trust or upon
distribution of Junior Subordinated Debentures to the holders of the Capital
Securities in exchange for all 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.
 
GOVERNING LAW
 
     The Guarantee will be governed by and construed in accordance with the laws
of the State of New York.
 
                                       48
<PAGE>   50
 
                       DESCRIPTION OF THE OLD SECURITIES
 
     The terms of the Old Securities are identical in all material respect to
the New Securities, except that the Old Securities have not been registered
under the Securities Act, are subject to certain restrictions on transfer and
are entitled to certain rights under the Registration Rights Agreement (which
rights will terminate upon consummation of the Exchange Offer, except under
limited circumstances). Holders of Old Capital Securities should review the
information set forth under "Risk Factors -- Certain Consequences of a Failure
to Exchange Old Capital Securities."
 
                   RELATIONSHIP AMONG THE CAPITAL SECURITIES,
              THE JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEE
 
     Payments of Distributions and other amounts due on the Capital Securities
(to the extent the Trust has funds available for the payment of such
Distributions) are irrevocably guaranteed by the Company as and to the extent
set forth under "Description of Guarantee." If and to the extent that the
Company does not make payments under the Junior Subordinated Debentures, the
Trust will not pay Distributions or other amounts due on the Capital Securities.
The Guarantee does not cover payment of Distributions when the Trust does not
have sufficient funds to pay such Distributions. A holder of Capital Securities
may institute a legal proceeding directly against the Company to enforce payment
of such Distributions to such holder after the respective due dates. Taken
together, the Company's obligations under the Junior Subordinated Debentures,
the Indenture and the Guarantee provide, in the aggregate, a full 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 and unconditional guarantee of the Trust's
obligations under the Capital Securities. The obligations of the Company under
the Guarantee and the Junior Subordinated Debentures are subordinate and junior
in right of payment to all Indebtedness of the Company.
 
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 of the Junior Subordinated Debentures
will be equal to the sum of the aggregate stated liquidation amount of the
Capital Securities and the 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
related Capital Securities; (iii) the Company shall pay for all and any costs,
expenses and liabilities of the Trust except the Trust's obligations under the
Capital Securities; and (iv) the Declaration further provides that the Trust
will not engage in any activity that is not consistent with the limited purposes
of the Trust.
 
     Notwithstanding anything to the contrary in the Indenture, the Company has
the right to set-off any payment it is otherwise required to make thereunder
with and to the extent the Company has theretofore made, or is concurrently on
the date of such payment making, a payment under the Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF CAPITAL SECURITIES
 
     A holder of Capital Securities may institute a legal proceeding directly
against the Company 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 Indebtedness of the Company will
not constitute a default or Indenture Event of Default. In addition, in the
event of payment defaults under, or acceleration of, Indebtedness of the
Company, the subordination provisions of the Indenture provide that no payments
may be made in respect of the Junior Subordinated Debentures until such
Indebtedness has been paid in full or any payment default thereunder has been
cured or waived. Failure to make required payments on the Junior Subordinated
Debentures would constitute an Indenture Event of Default under the Indenture.
 
                                       49
<PAGE>   51
 
LIMITED PURPOSE OF TRUST
 
     The Capital Securities evidence a beneficial interest in the Trust, and the
Trust exists for the sole purpose of issuing the Capital Securities and the
Common Securities and investing the proceeds thereof in Junior Subordinated
Debentures. 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 Company the
principal amount of and interest accrued on Junior Subordinated Debentures held,
while a holder of Capital Securities is entitled to receive Distributions from
the Trust (or from the Company under the Guarantee) if and to the extent the
Trust has funds available for the payment of such Distributions.
 
RIGHTS UPON TERMINATION
 
     Upon any voluntary or involuntary termination, winding-up or liquidation of
the Trust involving the liquidation of the Junior Subordinated Debentures, the
holders of the Capital Securities will be entitled to receive, out of assets
held by the Trust, the liquidation distribution in cash. See "Description of
Capital Securities -- Liquidation Distribution Upon Dissolution." Upon any
voluntary or involuntary liquidation or bankruptcy of the Company, the Property
Trustee, as holder of the Junior Subordinated Debentures, would be a
subordinated creditor of the Company, subordinated in right of payment to all
Indebtedness, but entitled to receive payment in full of principal and interest
before any stockholders of the Company receive payments or distributions. Since
the Company 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 the Capital Securities), the positions of a holder of Capital
Securities and a holder of the Junior Subordinated Debentures relative to other
creditors and to stockholders of the Company in the event of liquidation or
bankruptcy of the Company would be substantially the same.
 
             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
     In the opinion of Simpson Thacher & Bartlett, special United States federal
income tax counsel to the Company and the Trust ("Tax Counsel"), the following
summary accurately describes the material United States federal income tax
consequences that may be relevant to the purchase, ownership and disposition of
the Capital Securities. Unless otherwise stated, this summary deals only with
Capital Securities held as capital assets by United States persons (defined
below) who purchase the Capital Securities upon original issuance. As used
herein, a "United States person" means (i) a person that is a citizen or
resident of the United States, (ii) a corporation, partnership or other entity
created or organized in or under the laws of the United States or any political
subdivision thereof, (iii) an estate the income of which is subject to United
States federal income taxation regardless of its source, or (iv) a trust if a
court within the United States is able to exercise primary supervision over the
administration of such trust and one or more United States fiduciaries have the
authority to control all the substantial decisions of such trust. The tax
treatment of a holder may vary depending on such holder's particular situation.
This summary does not address all the tax consequences that may be relevant to a
particular holder or to holders who may be subject to special tax treatment,
such as banks, real estate investment trusts, regulated investment companies,
insurance companies, dealers in securities or currencies, or tax-exempt
investors. In addition, this summary does not include any description of any
alternative minimum tax consequences or the tax laws of any state, local or
foreign government that may be applicable to a holder of Capital Securities.
This summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury regulations promulgated thereunder and administrative and
judicial interpretations thereof, as of the date hereof, all of which are
subject to change, possibly on a retroactive basis. The authorities on which
this summary is based are subject to various interpretations and the opinions of
Tax Counsel are not binding on the Internal Revenue Service ("IRS") or the
courts, either of which could take a contrary position. Moreover, no rulings
have been or will be sought from the IRS with respect to the transactions
described herein. Accordingly, there can be no assurance that the IRS will not
challenge the opinions expressed herein or that a court would not sustain such a
challenge. Nevertheless, Tax Counsel has advised that it is of the view that, if
challenged, the opinions expressed herein would be sustained by a court with
jurisdiction in a properly presented case.
 
                                       50
<PAGE>   52
 
     HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, 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. FOR A DISCUSSION OF THE POSSIBLE REDEMPTION OF THE CAPITAL
SECURITIES UPON THE OCCURRENCE OF CERTAIN TAX EVENTS SEE "DESCRIPTION OF CAPITAL
SECURITIES -- REDEMPTION -- SPECIAL EVENT REDEMPTION OR DISTRIBUTION OF JUNIOR
SUBORDINATED DEBENTURES."
 
TAX CONSEQUENCES OF THE EXCHANGE
 
     The Exchange will not be a taxable event for United States federal income
tax purposes. Accordingly, holders who exchange their Old Capital Securities for
New Capital Securities pursuant to the Exchange Offer will not recognize any
gain or loss on such exchange for such purposes, such exchanging holders will
have a tax basis in their New Capital Securities that is equal to the adjusted
tax basis they had in their Old Capital Securities immediately before the
Exchange and the holding period for their New Capital Securities will include
the period during which they held their Old Capital Securities.
 
CLASSIFICATION OF THE TRUST
 
     In connection with the issuance of the Capital Securities, Tax Counsel is
of the opinion that under current law and assuming full compliance with the
terms of the Declaration, the Trust will be classified as a grantor trust for
United States federal income tax purposes and not as an association taxable as a
corporation. Accordingly, for United States federal income tax purposes, each
beneficial owner (a "holder") of Capital Securities generally will be considered
the owner of an undivided interest in the Junior Subordinated Debentures and,
thus, will be required to include in gross income its allocable share of the
income paid or accrued on the Junior Subordinated Debentures.
 
CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES
 
     The Company, 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 tax
purposes. In connection with the issuance of the Junior Subordinated Debentures,
Tax Counsel is of the opinion that, under current law, and based on certain
representations, facts and assumptions set forth in such opinion, the Junior
Subordinated Debentures will be classified as indebtedness for United States
federal income tax purposes.
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
 
     Under the applicable Treasury regulations, the Junior Subordinated
Debentures will not be treated as issued with original issue discount ("OID")
within the meaning of Section 1273(a) of the Code. Accordingly, except as set
forth below, the stated interest on the Junior Subordinated Debentures generally
will be taxable to a holder of Capital Securities as ordinary income at the time
it is paid or accrued in accordance with such holder's regular method of tax
accounting.
 
     If, however, the Company exercises its right to defer payments of interest
on the Junior Subordinated Debentures, the Junior Subordinated Debentures will
become OID instruments at such time and all holders of Capital Securities will
be required to accrue their allocable share of the stated interest (and de
minimis OID, if any) on the Junior Subordinated Debentures on a daily economic
accrual basis (using the constant-yield-to-maturity method of accrual described
in Section 1272 of the Code) during the Extension Period even though the Company
will not pay such interest until the end of the Extension Period, and even
though some holders may use the cash method of tax accounting. Moreover,
thereafter the Junior Subordinated Debentures will be taxed as OID instruments
for as long as they remain outstanding. Thus, even after the end of an Extension
Period, all holders would be required to continue to include their allocable
share of the stated interest (and de minimis OID, if any) on the Junior
Subordinated Debentures in income on a daily economic accrual basis, regardless
of their method of tax accounting and in advance of receipt of the cash
attributable to such income. Under the OID economic accrual rules, a holder
would accrue an amount of interest income each year that
 
                                       51
<PAGE>   53
 
approximates the stated amount of Distributions called for under the terms of
the Capital Securities, and actual cash payments in respect of such
Distributions would not be reported separately as taxable income. Any amount of
OID included in a holder's gross income (whether or not during an Extension
Period) with respect to a Capital Security will increase such holder's adjusted
tax basis in such Capital Security, and the amount of Distributions received by
a holder in respect of such accrued OID will reduce the adjusted tax basis of
such Capital Security.
 
     The Treasury regulations described above have not yet been addressed in any
rulings or other interpretations by the Internal Revenue Service ("IRS"), and it
is possible that the IRS could take a contrary position. If the IRS were to
assert successfully that the stated interest on the Junior Subordinated
Debentures was OID regardless of whether the Company exercises its option to
defer payments of interest on such debentures, all holders of Capital Securities
would be required to include such stated interest in income on a daily economic
accrual basis as described above.
 
     Corporate holders of Capital Securities will not be entitled to a
dividends-received deduction with respect to any income recognized by such
holders with respect to the Capital Securities.
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES OR CASH UPON LIQUIDATION OF THE
TRUST
 
     As described under the caption "Description of Junior Subordinated
Debentures -- Distribution of Junior Subordinated Debentures," Junior
Subordinated Debentures may be distributed to holders in exchange for the
Capital Securities and in liquidation of the Trust. Under current law, such a
distribution would be non-taxable, and will result in the holder receiving
directly its pro rata share of the Junior Subordinated Debentures previously
held indirectly through the Trust, with a holding period and aggregate tax basis
equal to the holding period and aggregate tax basis such holder had in its
Capital Securities before such distributions. If, however, the liquidation of
the Trust were to occur because the Trust is subject to United States federal
income tax with respect to income accrued or received on the Junior Subordinated
Debentures, the distribution of the Junior Subordinated Debentures to holders
would be a taxable event to the Trust and to each holder and a holder would
recognize gain or loss as if the holder had exchanged its Capital Securities for
the Junior Subordinated Debentures it received upon liquidation of the Trust.
 
     A holder would accrue interest in respect of the Junior Subordinated
Debentures received from the Trust in the manner described above under
"-- Interest Income and Original Issue Discount."
 
     Under certain circumstances described herein (see "Description of Capital
Securities -- Special Event Redemption or Distribution of Junior Subordinated
Debentures"), the Junior Subordinated Debentures may be redeemed for cash, with
the proceeds of such redemption distributed to holders in redemption of their
Capital Securities. Under current law, such a redemption would constitute a
taxable disposition of the redeemed Capital Securities for United States federal
income tax purposes, and a holder would 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 will recognize gain or loss equal to
the difference between the amount realized by the holder on the sale or
redemption of the Capital Securities (except to the extent that such amount
realized is characterized as a payment in respect of accrued but unpaid interest
on such holder's allocable share of the Junior Subordinated Debentures that such
holder has not included in gross income previously) and the holder's adjusted
tax basis in the Capital Securities sold or redeemed. 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 Taxpayer Relief Act of 1997 generally reduces the tax rates on capital
gains recognized by individuals on the sale or other taxable disposition of
capital assets held for more than 18 months. Holders are advised to consult with
their own tax advisors as to the consequences in their particular circumstances
of the capital gain provisions of the Taxpayer Relief Act of 1997. Subject to
certain limited exceptions, capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.
 
                                       52
<PAGE>   54
 
NON-UNITED STATES HOLDERS
 
     As used herein, the term "Non-United States Holder" means any holder that
is not a "United States person". As discussed above, the Capital Securities will
be treated as evidence of an indirect beneficial ownership interest in the
Junior Subordinated Debentures. See "-- Classification of the Trust." Thus,
under present United States federal income tax law, and subject to the
discussion below concerning backup withholding:
 
          (a) no withholding of United States federal income tax will be
     required with respect to the payment by the Company or any paying agent of
     principal or interest (which for purposes of this discussion includes any
     OID) with respect to the Capital Securities (or on the Junior Subordinated
     Debentures) to a Non-United States Holder, provided (i) that the beneficial
     owner of the Capital Securities (or Junior Subordinated Debentures)
     ("Beneficial Owner") does not actually or constructively own 10% or more of
     the total combined voting power of all classes of stock of the Company
     entitled to vote within the meaning of Section 871(h)(3) of the Code and
     the regulations thereunder, (ii) the Beneficial Owner is not a controlled
     foreign corporation that is related to the Company through stock ownership,
     (iii) the Beneficial Owner is not a bank whose receipt of interest with
     respect to the Capital Securities (or on the Junior Subordinated
     Debentures) is described in Section 881(c)(3)(A) of the Code and (iv) the
     Beneficial Owner satisfies the statement requirement (described generally
     below) set forth in Section 871(h) and Section 881(c) of the Code and the
     regulations thereunder; and
 
          (b) no withholding of United States federal income tax will be
     required with respect to any gain realized by a Non-United States Holder
     upon the sale or other disposition of the Capital Securities (or Junior
     Subordinated Debentures).
 
     To satisfy the requirement referred to in (a)(iv) above, the Beneficial
Owner, or a financial institution holding the Capital Securities (or Junior
Subordinated Debentures) on behalf of such owner, must provide, in accordance
with specified procedures, to the Trust or its paying agent, a statement to the
effect that the Beneficial Owner is not a United States Holder. Pursuant to
current temporary Treasury regulations, these requirements will be met if (1)
the Beneficial Owner provides his name and address, and certifies, under
penalties of perjury, that it is not a United States person (which certification
may be made on an IRS Form W-8 (or successor form)) or (2) a financial
institution holding the Capital Securities (or Junior Subordinated Debentures)
on behalf of the Beneficial Owner certifies, under penalties of perjury, that
such statement has been received by it and furnishes a paying agent with a copy
thereof.
 
     If a Non-United States Holder cannot satisfy the requirements of the
"portfolio interest" exception described in (a) above, payments of premium, if
any, and interest (including any OID) made to such Non-United States Holder with
respect to the Capital Securities (or on the Junior Subordinated Debentures)
will be subject to a 30% United States Federal withholding tax unless the
Beneficial Owner provides the Company or its paying agent (a "Paying Agent"), as
the case may be, with a properly executed (1) IRS Form 1001 (or successor form)
claiming an exemption from, or a reduction of, such withholding tax under the
benefit of a United States income tax treaty or (2) IRS Form 4224 (or successor
form) stating that interest paid with respect to the Capital Securities (or on
the Junior Subordinated Debentures) is not subject to withholding tax because it
is effectively connected with the Beneficial Owner's conduct of a trade or
business in the United States.
 
     If a Non-United States Holder is engaged in a trade or business in the
United States and interest with respect to the Capital Securities (or on the
Junior Subordinated Debentures) is effectively connected with the conduct of
such trade or business, the Non-United States Holder, although exempt from the
withholding tax discussed above, will be subject to United States federal income
tax on such interest on a net income basis in the same manner as if it were a
United States person. In addition, if such Non-United States Holder is a foreign
corporation, it may be subject to a branch profits tax equal to 30% of its
effectively connected earnings and profits for the taxable year, subject to
adjustments. For this purpose, such interest would be included in such foreign
corporation's earnings and profits.
 
     Any gain realized upon the sale or other taxable disposition of the Capital
Securities (or Junior Subordinated Debentures) generally will not be subject to
United States federal income tax unless (i) such
 
                                       53
<PAGE>   55
 
gain is effectively connected with a trade or business carried on in the United
States by a Non-United States Holder, (ii) in the case of a Non-United States
Holder who is an individual, such individual is present in the United States for
183 days or more in the taxable year of such sale or disposition and certain
other conditions are met, and (iii) in the case of any gain representing accrued
interest with respect to the Capital Securities (or Junior Subordinated
Debentures), the requirements described above are not satisfied.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     Income on the Capital Securities (or Junior Subordinated Debentures) held
of record by United States Holders (other than corporations and other exempt
holders) will be reported annually to such holders and to the IRS. The Regular
Trustees currently intend to deliver such reports to holders of record prior to
January 31 following each calendar year. It is anticipated that persons who hold
Capital Securities (or Junior Subordinated Debentures) as nominees for
beneficial holders will report the required tax information to beneficial
holders on Form 1099.
 
     "Backup withholding" at a rate of 31% will apply to payments of interest to
non-exempt United States persons unless the holder furnishes its taxpayer
identification number in the manner prescribed in applicable Treasury
regulations, certifies that such number is correct, certifies as to no loss of
exemption from backup withholding and meets certain other conditions.
 
     No information reporting or backup withholding will be required with
respect to payments made by the Trust or any Paying Agent to Non-United States
Holders if a statement described in (a)(iv) under "Non-United States Holders"
has been received and the payor does not have actual knowledge that the
beneficial owner is a United States person.
 
     In addition, backup withholding and information reporting will not apply if
payments of the principal, interest, OID or premium with respect to the Capital
Securities (or on the Junior Subordinated Debentures) are paid or collected by a
foreign office of a custodian, nominee or other foreign agent on behalf of the
Beneficial Owner, or if a foreign office of a broker (as defined in applicable
Treasury regulations) pays the proceeds of the sale of the Capital Securities
(or Junior Subordinated Debentures) to the owner thereof. If, however, such
nominee, custodian, agent or broker is, for United States federal income tax
purposes, a United States person, a controlled foreign corporation or a foreign
person that derives 50% or more of its gross income for certain periods from the
conduct of a trade or business in the United States, such payments will not be
subject to backup withholding but will be subject to information reporting,
unless (1) such custodian, nominee, agent or broker has documentary evidence in
its records that the Beneficial Owner is not a United States person and certain
other conditions are met or (2) the Beneficial Owner otherwise establishes an
exemption.
 
     Payment of the proceeds from disposition of Capital Securities (or Junior
Subordinated Debentures) to or through a United States office of a broker is
subject to information reporting and backup withholding unless the holder or
beneficial owner establishes an exemption from information reporting and backup
withholding.
 
     Any amounts withheld from a holder of the Capital Securities (or Junior
Subordinated Debentures) under the backup withholding rules will be allowed as a
refund or a credit against such holder's United States federal income tax
liability, provided the required information is furnished to the IRS.
 
                              BOOK-ENTRY ISSUANCE
 
     The New Capital Securities initially will be represented by one or more
Capital Securities in registered, global form (the "Global Capital Securities").
The Global Capital Securities will be deposited upon issuance with the Property
Trustee as custodian for The Depository Trust Company ("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. Beneficial interests in the Global Capital
Securities may not be exchanged for Capital Securities in certificated form
except in the limited circumstances described below.
 
                                       54
<PAGE>   56
 
     DTC has advised the Trust and the Company that DTC is a limited-purpose
trust company 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. The Participants
include securities brokers and dealers (including the Initial Purchasers),
banks, trust companies, clearing corporations and certain other organizations.
Access to DTC's system is also 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 has also advised the Trust and the Company that, pursuant to procedures
established by it, (i) upon deposit of the Global Capital Securities, DTC will
credit the accounts of Participants with their respective portions of the
principal 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 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 interests in the Global Capital
Securities will not have Capital Securities registered in their name, will not
received physical delivery of Capital Securities in certificated form and will
not be considered the registered owners or holders thereof for any purpose.
 
     Payments in respect of the Global Capital Security registered in the name
DTC or its nominee will be payable by the Property Trustee to DTC in its
capacity as the registered holder. 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
ownership 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 ownership 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 Company 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
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 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 or the Trust. Neither the Trust nor 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 and
the Property Trustee may conclusively rely on and will be protected in relying
on instructions from DTC or its nominee for all purposes.
 
     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. Transfers between
Participants in DTC will be effected in accordance with DTC's procedures, and
will be settled in same-day funds.
 
     DTC has advised the Trust and the Company that it will take any action
permitted to be taken by a holder of Capital Securities only at the direction of
one or more Participants to whose account with DTC interests in the Global
Capital Securities are credited. However, if there is an Event of Default, DTC
reserves the right to exchange the Global Capital Securities for legended
Capital Securities in certificated form and to distribute such Capital
Securities to its Participants.
 
     Although DTC has agreed to the foregoing procedures to facilitate transfers
of interest in the Global Capital Securities among participants in DTC, it is
under no obligation to perform or to continue to perform such procedures, and
such procedures may be discontinued at any time. Neither the Trust nor the
Property
 
                                       55
<PAGE>   57
 
Trustee will have any responsibility for the performance by DTC, or its
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations.
 
     A Global Capital Security is exchangeable for Capital Securities in
registered certificated for if (1) DTC (x) notifies the Trust that it is
unwilling or unable to continue as Depository for the Global Capital Security
and the Trust thereupon fails to appoint a successor Depositary or (y) has
ceased to be a clearing agency registered under the Exchange Act, (ii) the Trust
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. In all cases, certificated Capital
Securities delivered in exchange for any Global Capital Security or beneficial
interests therein will be registered in the names, and issued in any approved
dominations, requested by or on behalf of the Depositary (in accordance with its
customary procedures).
 
     The information in this section concerning DTC and its book-entry system
has been obtained from sources that the Trust and the Company believe to be
reliable, but neither the Trust nor the Company takes responsibility for the
accuracy thereof.
 
                              ERISA CONSIDERATIONS
 
     Generally, employee benefit plans that are subject to the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or Section 4975 of
the Code ("Plans"), may purchase Capital Securities, subject to the investing
fiduciary's determination that the investment in Capital Securities satisfies
ERISA's fiduciary standards and other requirements applicable to investments by
the Plan.
 
     The Department of Labor ("DOL") has issued a regulation (29 C.F.R. Section
2510.3-101) (the "DOL Regulation") concerning the definition of what constitutes
the assets of a Plan. The DOL Regulation provides that as a general rule, the
underlying assets and properties of corporations, partnerships, trusts and
certain other entities in which a plan makes an "equity" investment will be
deemed for purposes of ERISA to be assets of the investing plan unless certain
exceptions apply.
 
     There can be no assurance that any of the exceptions set forth in the DOL
Regulation will apply to the purchase of Capital Securities offered hereby and,
as a result, an investing Plan's assets could be considered to include an
undivided interest in the Junior Subordinated Debentures held by the Trust. In
the event that the assets of the Trust are considered assets of an investing
Plan, the Company, the Trustees and other persons, in providing services with
respect to the Junior Subordinated Debentures, may be considered fiduciaries to
such Plan and subject to the fiduciary responsibility provisions of Title I of
ERISA (including the prohibited transaction provisions thereof). In addition,
the prohibited transaction provisions of Section 4975 of the Code could apply
with respect to transactions engaged in by any "disqualified person," as defined
below, involving such assets unless a statutory or administrative exemption
applies.
 
     Even if they are not fiduciaries, the Company and/or any of its affiliates
may be considered a "party in interest" (within the meaning of ERISA) or a
"disqualified person" (within the meaning of Section 4975 of the Code) with
respect to certain Plans. The acquisition and ownership of Capital Securities by
a Plan (including an individual retirement arrangement or other plan described
in Section 4975(e)(1) of the Code) 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. As a result, Plans with respect to which the Company or any of its
affiliates is a party in interest or a disqualified person should not acquire
Capital Securities unless such Capital Securities are acquired pursuant to and
in accordance with an applicable prohibited transaction exemption.
 
     Notwithstanding the foregoing, it is possible that the New Capital
Securities may qualify as "publicly offered securities" under the DOL Regulation
if, in addition to the Exchange Offer, they are also "widely held" and "freely
transferable" at the time of the Exchange Offer. Under the DOL Regulation, a
class of securities is "widely held" only if it is a class of securities owned
by 100 or more investors independent of the issuer and each other. Although it
is possible that at the time of the Exchange Offer the New Capital Securities
will be "widely held", no assurances can be given that that will be true. If the
New Capital Securities are "publicly offered securities" at the time of the
Exchange Offer, the assets of the Trust would not
 
                                       56
<PAGE>   58
 
be assets of any Plan purchasing such securities as of such time. If the New
Capital Securities did not qualify as "publicly offered securities", the
foregoing discussion about plan assets would also apply to the New Capital
Securities.
 
     Any Plans or other entities whose assets include Plan assets subject to
ERISA or Section 4975 of the Code proposing to acquire Capital Securities or New
Capital Securities should consult with their own counsel.
 
                              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 Company has 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 180 days after the Registration Statement of
which this Prospectus constitutes a part is declared effective. See "The
Exchange Offer -- Resales of New Capital Securities." The Company 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 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.
 
                                 LEGAL MATTERS
 
     Certain matters of Delaware law relating to the validity of the New Capital
Securities will be passed upon for the Company and the Trust by Richards, Layton
& Finger, special Delaware counsel to the Company and the Trust. The validity of
the New Junior Subordinated Debentures and the New Guarantee will be passed upon
for the Company and the Trust by Jennie P. Carlson, Senior Vice President,
General Counsel and Secretary for the Company, and by Simpson Thacher & Bartlett
(a partnership which includes professional corporations). Certain United States
federal income taxation matters also will be passed upon for the Company and the
Trust by Simpson Thacher & Bartlett.
 
                              INDEPENDENT AUDITORS
 
     The consolidated financial statements of the Company and its affiliates as
of December 31, 1996 and for the year then ended incorporated by reference in
this Prospectus have been audited by Arthur Andersen LLP, independent public
accountants, as stated in their report appearing therein.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Ohio Revised Code, Section 1701.13(E), allows indemnification by the
Company to any person made or threatened to be made a party to any proceedings,
other than a proceeding by or in the right of the Company, by reason of the fact
that he is or was a director, officer, employee or agent of the Company, against
expenses, including judgment and fines, if he acted in good faith and in a
manner reasonably believed to be in or not opposed to the best interests of the
Company and, with respect to criminal actions, in which he had no reasonable
cause to believe that his conduct was unlawful. Similar provisions apply to
actions brought by or in the right of the Company, except that no
indemnification shall be made in such cases when the person shall have been
adjudged to be liable for negligence or misconduct to the Company unless deemed
otherwise by the court. Indemnification is to be made by a majority vote of a
quorum of disinterested directors or the written opinion of independent counsel
or by the shareholders or by the court. The Company's Code of Regulations
extends such indemnification.
 
     Under the Declaration, the Debenture Issuer agreed to indemnify each
Company Indemnified Person (as defined therein) 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 Debenture Issuer Indemnified Person against expenses
(including attorney fees), 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.

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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of each
Registrant pursuant to the provisions, or otherwise, each Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by each Registrant of expenses incurred
or paid by a director, officer 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.
 
     The undersigned registrants hereby undertake 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.
 
     The undersigned registrants hereby undertake 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.

their duly designated proxies) shall be entitled to give or take, or vote on,
the relevant action.

            (d) The ownership of Securities shall be proved by the Security
Register.

            (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security

                                                                              13


and the Holder of every Security issued upon the registration of transfer
thereof or in exchange therefor or in lieu thereof in respect of anything done,
omitted or suffered to be done by the Trustee or the Company in reliance
thereon, whether or not notation of such action is made upon such Security.

SECTION 105. Notices, Etc. to Trustee and the Company.

            Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with:

            (1) the Trustee by any Holder or by the Company shall be sufficient
for every purpose hereunder if made, given, furnished or filed in writing to or
with the Trustee at its Corporate Trust Office, Attention: Corporate Trust
Division; or

            (2) the Company by the Trustee or by any Holder shall be sufficient
for every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to it
at the address of its principal office specified in the first paragraph of this
instrument or at any other address previously furnished in writing to the
Trustee by the Company.

SECTION 106. Notice to Holders; Waiver.

            Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

            In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made by telecopier or overnight air courier
guaranteeing next day delivery.

SECTION 107. Conflict With Trust Indenture Act.

            If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the provision of the Trust Indenture Act
shall control. If any provision of this Indenture modifies or excludes any
provision of the Trust Indenture Act that may be so modified or
<PAGE>   24
                                                                              14


excluded, the latter provision shall be deemed to apply to this Indenture as to
modified or so be excluded, as the case may be.

SECTION 108. Effect of Headings and Table of Contents.

            The Article and Section headings herein and the Table of Contents
are for convenience only and shall not affect the construction hereof.

SECTION 109. Separability Clause.

            In case any provision in this Indenture or in the Securities shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

SECTION 110. Benefits of Indenture.

            Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder, the holders of Indebtedness, the holders of Capital Securities (to
the extent provided herein) and the Holders of Securities, any benefit or any
legal or equitable right, remedy or claim under this Indenture.

SECTION 111. GOVERNING LAW.

            THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS
OF LAWS PRINCIPLES THEREOF. THIS INDENTURE IS SUBJECT TO THE PROVISIONS OF THE
TRUST INDENTURE ACT THAT ARE REQUIRED TO BE PART OF THIS INDENTURE AND SHALL, TO
THE EXTENT APPLICABLE, BE GOVERNED BY SUCH PROVISIONS.

SECTION 112. Legal Holidays.

            In any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of interest or principal of the Securities need not be made on such
date, but may be made on the next succeeding Business Day (except that, if such
Business Day is in the next succeeding calendar year, such Interest Payment
Date, Redemption Date or Stated Maturity, as the case may be, shall be the
immediately preceding Business Day) with the same force and effect as if made on
the Interest Payment Date or Redemption Date, or at the Stated Maturity,
provided that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

                                   ARTICLE TWO

                                 SECURITY FORMS

            The Junior Subordinated Securities in definitive form and the New
Junior Subordinated Securities in definitive form shall be in the form attached
hereto as Exhibit A; provided, that the New Junior Subordinated Securities shall
not contain any of the provisions following the Trustee's authentication.

            If the Securities are distributed to the holders of Capital
Securities and Common Securities, the record holder (including any Depositary)
of any Capital Securities or Common Securities shall be issued Securities in
definitive, fully registered form without interest coupons, substantially in the
form of Exhibit A hereto, with the legends in substantially the form of the
legends existing on the security representing the Capital Securities or Common
Securities to be exchanged (with such changes thereto as the officers executing
such Securities determine to be necessary or appropriate, as evidenced by their
execution of the Securities) and such other legends as may be applicable thereto
(including any legend required by Section 313 or Section 314 hereof), duly
executed by the Company and authenticated by the Trustee or the Authenticating
Agent as provided herein, which Securities, if to be held in global form by any
Depositary, may be deposited on behalf of the holders of the Securities
represented thereby with the Trustee, as custodian for the Depositary, and
registered in the name of a nominee of the Depositary.

            Any Global Security shall represent such of the outstanding
Securities as shall be specified therein and shall provide that it shall
represent the aggregate amount of outstanding Securities from time to time
endorsed thereon and that the aggregate amount of outstanding Securities
represented thereby may from time to time be increased or reduced to reflect
transfers or exchanges permitted hereby. 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 or the Custodian, at
the direction of the Trustee, in such manner and upon instructions given by the
holder of such Securities in accordance with the Indenture. Payment of
principal, interest and premium, if any, on any Global Security shall be made to
the holder of such Global Security.

            The Securities shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture, and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with the rules of any securities exchange or as may, consistently herewith, be
determined by the officers executing such Securities, as evidenced by their
execution of the Securities.

            The definitive Securities shall be printed, lithographed or engraved
or produced by any combination of these or other methods, all as determined by
the officers executing such Securities, as evidenced by their execution of such
Securities.

                                  ARTICLE THREE

                                 THE SECURITIES

SECTION 301. Title and Terms.

            The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is unlimited.

            The Securities' Stated Maturity shall be June 15, 2027.

            The Securities shall bear interest at a variable per annum rate
equal to LIBOR plus 0.765%, from June 8, 1997 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, as the case
may be, payable quarterly (subject to deferral as set forth herein), in arrears,
on the 15th day of June, September, December and March of each year, commencing
September 15, 1997, until the principal thereof is paid or made available for
payment. Interest will compound quarterly and will accrue at a variable per
annum rate equal to LIBOR plus 0.765%, to the extent permitted by applicable
law, on any interest installment in arrears for more than one quarterly period
or during an extension of an interest payment period as set forth below in this
Section 301. In the event that any date on which interest is payable on the
Securities is not a Business Day, then a payment of the interest payable on such
date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay).

            The Company shall have the right, at any time during the term of the
Securities, from time to time, to defer payment of interest on such Security for
up to 20 consecutive quarterly periods (an "Extension Period") provided that no
Extension Period may extend past the Stated Maturity of the Security. There may
be multiple Extension Periods of varying lengths during the term of the
Securities. At the end of each Extension Period, if any, the Company shall pay
all interest then accrued and unpaid, together with interest thereon, compounded
quarterly at the rate specified on the Security to the extent permitted by
applicable law. Prior to the termination of any such Extension Period, the
Company may further extend the interest payment period, provided that no
Extension Period may exceed 20 consecutive quarterly periods or extend beyond
the Stated Maturity of the Securities. Upon the termination of any such
Extension Period and the payment of all amounts then due on any Interest Payment
Date, the Company may elect to begin a new Extension Period subject to the above
requirements. No interest shall be due and payable during an Extension Period,
except at the end thereof. The Company shall give the Property Trustee and the
Regular Trustees written notice of its election of such Extension Period at
least one Business Day prior to the record date for the related interest
payment.

            The principal of and interest on the Securities shall be payable at
the office or agency of the Paying Agent in the United States maintained for
such purpose and at any other office or agency maintained by the Company for
such purpose in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may

                                                                              17


be made (i) by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Security Register.

            The Securities shall be subordinated in right of payment to
Indebtedness as provided in Article Eleven.

            The Securities shall be redeemable as provided in Article Twelve.

SECTION 302. Denominations.

            The Securities shall be issuable only in registered form, without
coupons, and only in denominations of $1,000 and any integral multiple thereof.

SECTION 303. Execution, Authentication, Delivery and Dating.

            The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President or one of
its Vice Presidents. The signature of any of these officers on the Securities
may be manual or facsimile.

            Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

            In the event that the Company elects to issue additional Junior
Subordinated Debentures hereunder on a subsequent Closing Date, the Company
shall deliver to the Trustee, in the manner provided under the following
paragraph, duly executed Securities and a Company Order, together with such
Officers' Certificates, Board Resolutions and Opinions of Counsel (in each case
in substantially the form delivered at the initial Closing Date), as are
required for the issuance of Securities under this Indenture.

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and make available for delivery such
Securities as in this Indenture provided and not otherwise.

            Each Security shall be dated the date of its authentication.

            No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

                                                                              18


SECTION 304. Temporary Securities.

            Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and make
available for delivery, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, 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
evidenced by their execution of such Securities.

            If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Company designated pursuant to Section
1002, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor a like
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 305. Registration; Registration of Transfer and Exchange.

            The Company shall cause to be kept at the Corporate Trust Office of
the Trustee, a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 1002 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

            Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 1002 for such
purpose, the Company 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 any authorized denominations and of a like
aggregate principal amount.

            At the option of the Holder, Securities may be exchanged for other
Securities 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 Company
shall execute, and the Trustee shall authenticate and make available for
delivery, the Securities which the Holder making the exchange is entitled to
receive.

            All Securities issued upon any registration of transfer or exchange
of Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the
<PAGE>   29
                                                                              19


same benefits under this Indenture, as the Securities surrendered upon such
registration of transfer or exchange.

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

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Sections 304, 906 or 1208 not involving any transfer.

            If the Securities are to be redeemed in part, the Company shall not
be required (A) to issue, register the transfer of or exchange any Securities
during a period beginning at the opening of business 15 days before the day of
the mailing of a notice of redemption of any such Securities selected for
redemption under Section 1204 and ending at the close of business on the day of
such mailing, or (B) to 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.

            So long as the Securities are eligible for book-entry settlement
with the Depositary, or unless otherwise required by law, all Securities to be
traded on the PORTAL Market shall be represented by a Restricted Global Security
registered in the name of the Depositary or the nominee of the Depositary.

            The transfer and exchange of beneficial interests in any Global
Security, which does not involve the issuance of a definitive Security or the
transfer of interests to another Global Security, shall be effected through the
Depositary (but not the Trustee or the Custodian) in accordance with this
Indenture (including the restrictions on transfer set forth herein) and the
procedures of the Depositary therefor. Neither the Trustee nor the Custodian (in
such respective capacities) will have any responsibility for the transfer and
exchange of beneficial interests in such Global Security that does not involve
the issuance of a definitive Security or the transfer of interests to another
Global Security.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

            If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and make available for delivery
in exchange therefor a new Security of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

            If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity
<PAGE>   30
                                                                              20


as may be required by them to save each of them and any agent of either of them
harmless, then, in the absence of notice to the Company or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and the Trustee shall authenticate and make available for delivery, in lieu of
any such destroyed, lost or stolen Security, a new Security of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

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

            Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

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

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

SECTION 307. Payment of Interest; Interest Rights Preserved.

            Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

            Any interest on any Security which 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 may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

            (1) The Company may elect to make payment of any Defaulted Interest
to the Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest, which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Security and the date of the
proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be
<PAGE>   31
                                                                              21


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 be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee
shall promptly notify the Company of such Special Record Date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder at his 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 so mailed, such Defaulted Interest shall be paid to
the Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (2).

            (2) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and if so listed, upon such
notice as may be required by such exchange, if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee. Subject to the
foregoing provisions of this Section, each Security delivered under this
Indenture upon registration of transfer of or in exchange for or in lieu of any
other Security shall carry the rights to interest accrued and unpaid, and to
accrue which, which were carried by such other Security.

            In the event that a Registration Default (as defined in the
Registration Rights Agreement) occurs, additional interest ("Additional
Interest") shall become payable in respect of the Securities with respect to the
first 90-day period immediately following the occurrence of such Registration
Default, in an amount equal to $.25 per week per $1,000 principal amount of
Securities for each week or portion thereof that the Registration Default
continues. Additional Interest will increase by an additional $.05 per $1,000
principal amount of Securities with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum amount of
Additional Interest of $.50 per $1,000 principal amount of Securities.

SECTION 308. Persons Deemed Owners.

            Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee shall treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 307) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.
<PAGE>   32
                                                                              22


SECTION 309. Cancellation.

            All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of as directed by a Company Order, provided,
however, that the Trustee may but shall not be required to destroy such
Securities.

SECTION 310. Computation of Interest.

            The Company shall appoint a Calculation Agent, which may be the
Trustee, to determine LIBOR as of the Determination Date for each quarterly
interest period and to calculate the interest rate and the amount of interest
due for each such interest period. Absent manifest error, the Calculation
Agent's determination of LIBOR and its calculation of the interest rate for each
interest period shall be final and binding on the holders of the Securities.

            Interest on the Securities shall be computed on the basis of the
actual number of days elapsed in a year of twelve 30-day months. The amount of
interest payable for any period shorter than a full quarterly period for which
interest is computed will be computed on the basis of actual number of days
elapsed in such 90-day quarterly period.

SECTION 311. Right of Set-off.

            Notwithstanding anything to the contrary in the Indenture, the
Company shall have the right to set-off any payment it is otherwise required to
make thereunder to the extent the Company has theretofore made, or is
concurrently on the date of such payment making, a related payment under the
Guarantee.

SECTION 312. CUSIP Numbers.

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

SECTION 313. Global Securities.

            If the Securities are distributed to the holders of Capital
Securities, such Securities distributed in respect of Capital Securities that
are held in global form by a Depositary will initially be issued as a Global
Security, unless such transfer cannot be effected through book-entry settlement.
If the Company shall establish that the Securities are to be issued in the form
of one or more Global Securities, then the Company shall execute and the Trustee
shall, in accordance with Section 303 and the Company Order, authenticate and
deliver one or more Global Securities that (i) shall represent and shall be
denominated in an amount equal to the aggregate principal amount of all of the
Securities to be issued in the form of Global Securities and not yet cancelled,
(ii) shall be registered in the name of the Depositary for such Global Security
or Securities or the nominee of such Depositary, and (iii) shall be delivered by
the Trustee to such Depositary or pursuant to such Depositary's instructions.
Global Securities shall bear a legend substantially to the following effect:

            "This Security is a Global Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depositary
or a nominee of a Depositary. Notwithstanding the provisions of Section 305,
unless and until it is exchanged in whole or in part for Securities in
definitive registered form, a Global Security representing all or a part of the
Securities may not be transferred in the manner provided in Section 305 except
as a whole by the Depositary to a nominee of such Depositary or by a nominee of
such Depositary to such Depositary or another nominee of such Depositary or by
such Depositary or any such nominee to a successor Depositary or a nominee of
such successor Depositary. Every Security delivered upon registration or
transfer of, or in exchange for, or in lieu of, this Global Security shall be a
Global Security subject to the foregoing, except in the limited circumstances
described above. Unless this certificate is presented by an authorized
representative of The Depository Trust Company, a New York corporation ("DTC"),
to the Company or its agent for registration of transfer, exchange or payment,
and any certificate issued is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC (and any
payment is to be made to Cede & Co. or to such other entity as is requested by
an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
registered owner hereof, Cede & Co., has an interest herein."

            Definitive Securities issued in exchange for all or a part of a
Global Security pursuant to this Section 313 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. Upon execution and authentication, the Trustee shall deliver such
definitive Securities to the persons in whose names such definitive Securities
are so registered.

            At such time as all interests in Global Securities have been
redeemed, repurchased or canceled, such Global Securities shall be, upon receipt
thereof, canceled by the Trustee in accordance with standing procedures and
instructions existing between the Depositary and the Custodian. At any time
prior to such cancellation, if any interest in
<PAGE>   34
                                                                              24


Global Securities is exchanged for definitive Securities, redeemed, canceled or
transferred to a transferee who receives definitive Securities therefor or any
definitive Security is exchanged or transferred for part of Global Securities,
the principal amount of such Global Securities shall, in accordance with the
standing procedures and instructions existing between the Depositary and the
Custodian, be reduced or increased, as the case may be, and an endorsement shall
be made on such Global Securities by the Trustee or the Custodian, at the
direction of the Trustee, to reflect such reduction or increase.

            The Company and the Trustee may for all purposes, including the
making of payments due on the Securities, deal with the Depositary as the
authorized representative of the Holders for the purposes of exercising the
rights of Holders hereunder. The rights of the owner of any beneficial interest
in a Global Security shall be limited to those established by law and agreements
between such owners and depository participants or Euroclear and Cedel;
provided, that no such agreement shall give any rights to any person against the
Company or the Trustee without the written consent of the parties so affected.
Multiple requests and directions from and votes of the Depositary as holder of
Securities in global form with respect to any particular matter shall not be
deemed inconsistent to the extent they do not represent an amount of Securities
in excess of those held in the name of the Depositary or its nominee.

            If at any time the Depositary for any Securities represented by one
or more Global Securities notifies the Company that it is unwilling or unable to
continue as Depositary for such Securities or if at any time the Depositary for
such Securities shall no longer be eligible under this Section 313, the Company
shall appoint a successor Depositary with respect to such Securities. If a
successor Depositary for such Securities is not appointed by the Company within
90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company's election that such Securities be represented by one
or more Global Securities shall no longer be effective and the Company shall
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of definitive Securities, will authenticate and make available for
delivery Securities in definitive registered form, in any authorized
denominations, in an aggregate principal amount equal to the principal amount of
the Global Security or Securities representing such Securities in exchange for
such Global Security or Securities.

            The Company may at any time and in its sole discretion determine
that the Securities issued in the form of one or more Global Securities shall no
longer be represented by a Global Security or Securities. In such event the
Company shall execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive Securities, shall authenticate and
make available for delivery, Securities in definitive registered form, in any
authorized denominations, in an aggregate principal amount equal to the
principal amount of the Global Security or Securities representing such
Securities, in exchange for such Global Security or Securities.

            Notwithstanding any other provisions of this Indenture (other than
the provisions set forth in Section 314(a)), Global Securities may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary
<PAGE>   35
                                                                              25


to the Depositary or another nominee of the Depositary or by the Depositary or
any such nominee to a successor Depositary or a nominee of such successor
Depositary.

            Interests of beneficial owners in Global Security may be transferred
or exchanged for definitive Securities and definitive Securities may be
transferred or exchange for Global Securities in accordance with rules of the
Depositary and the provisions of Section 315.

            Any Security in global form may be endorsed with or have
incorporated in the text thereof such legends or recitals or changes not
inconsistent with the provisions of this Indenture as may be required by the
Custodian, the Depositary or by the National Association of Securities Dealers,
Inc. in order for the Securities to be tradeable on the PORTAL Market or as may
be required for the Securities to be tradeable on any other market developed for
trading of securities pursuant to Rule 144A or required to comply with any
applicable law or any regulation thereunder or with Regulation S or with the
rules and regulations of any securities exchange upon which the Securities may
be listed or traded or to conform with any usage with respect thereto, or to
indicate any special limitations or restrictions to which any particular
Securities are subject.

SECTION 314. Restrictive Legend.

            (a) Each Global Security and definitive Security that constitutes a
Restricted Security shall bear the following legend (the "Private Placement
Legend") on the face thereof until three years after the later of the date of
original issue and the last date on which the Company or any Affiliate of the
Company was the owner of such Capital Securities (or any predecessor thereto)
(the "Resale Restriction Termination Date"), unless otherwise agreed by the
Company and the Holder thereof:

            "THIS SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER
      THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
      STATE SECURITIES LAWS AND NEITHER THIS SECURITY NOR ANY INTEREST OR
      PARTICIPATION HEREIN MAY BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE
      ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH
      PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER MAY BE
      RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE
      SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THIS
      SECURITY, BY ITS ACCEPTANCE HEREOF, REPRESENTS, ACKNOWLEDGES AND AGREES
      FOR THE BENEFIT OF THE COMPANY THAT: (I) IT HAS ACQUIRED A "RESTRICTED"
      SECURITY WHICH HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT; (II) IT
      WILL NOT OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY PRIOR TO THE
      LATER OF THE DATE WHICH IS THREE YEARS AFTER THE DATE OF ORIGINAL ISSUANCE

      EXCEPT (A) TO THE COMPANY, (B) PURSUANT TO A REGISTRATION STATEMENT WHICH
      HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS
      THIS SECURITY IS ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON
      WHO THE SELLER REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER"
      (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION
      MEETING THE REQUIREMENTS OF RULE 144A, (D) OUTSIDE THE UNITED STATES IN A
      TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT,

      PURSUANT TO THE FOREGOING CLAUSES (II)(D), (E) AND (F) IS SUBJECT TO THE
      RIGHT OF THE ISSUER OF THIS SECURITY AND THE TRUSTEE FOR SUCH SECURITIES
      TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATIONS OR OTHER
      INFORMATION ACCEPTABLE TO THEM IN FORM AND SUBSTANCE."

            Any Security (or security issued in exchange or substitution
therefor) as to which such restrictions on transfer shall have expired in
accordance with their terms may, upon satisfaction of the requirements of
Section 314(b) and surrender of such Security for exchange to the Security
Registrar in accordance with the provisions of this Section 314, be exchanged
for a new Security or Securities, of like tenor and aggregate principal amount,
which shall not bear the restrictive legend required by this Section 314(a).

            (b) Upon any sale or transfer of any Restricted Security (including
any interest in a Global Security) (i) that is effected pursuant to an effective
registration statement under the Securities Act or (ii) in connection with which
the Trustee receives certificates and other information (including an opinion of
counsel, if requested) reasonably acceptable to the Company and the Trustee to
the effect that such security will no longer be subject to the resale
restrictions under federal and state securities laws, then (A) in the case of a
Restricted Security in definitive form, the Security Registrar or co-Registrar
shall permit the holder thereof to exchange such Restricted Security for a
Security that does not bear the legend set forth in Section 314(a), and shall
rescind any such restrictions on transfer and (B) in the case of Restricted
Securities represented by a Global Security, such Security shall no longer be
subject to the restrictions contained in the legend set forth in Section 314(a)
(but still subject

to the other provisions hereof). In addition, any Security (or Security issued
in exchange or substitution therefor) as to which the restrictions on transfer
described in the legend set forth in Section 314(a) have expired by their terms,
may, upon surrender thereof (in accordance with the terms of this Indenture)
together with such certifications and other information (including an Opinion of
Counsel having substantial experience in practice under the Securities Act and
otherwise reasonably acceptable to the Company, addressed to the Company and the
Trustee and in a form acceptable to the Company, to the effect that the transfer
of such Restricted Security has been made in compliance with Rule 144 or such
successor provision) acceptable to the Company and the Trustee as either of them
may reasonably require, be exchanged for a new Security or Securities of like
tenor and aggregate principal amount, which shall not bear the restrictive
legends set forth in Section 314(a).

SECTION 315. Special Transfer Provisions.

            At any time at the request of the beneficial holder of an interest
in a Security in global form, such beneficial holder shall be entitled to obtain
a definitive Security upon written request to the Trustee in accordance with the
standing instructions and procedures existing between the Depositary and the
Trustee for the issuance thereof. Upon receipt of any such request, the Trustee
will cause the aggregate principal amount of the Security in global form to be
reduced and, following such reduction, the Company will execute and the Trustee
will authenticate and deliver to such beneficial holder (or its nominee) a
Security or Securities in the appropriate aggregate principal amount in the name
of such beneficial holder (or its nominee) and bearing such restrictive legends
as may be required by this Indenture.

            Any transfer of a beneficial interest in a Security in global form
which cannot be effected through book-entry settlement must be effected by the
delivery to the transferee (or its nominee) of a definitive Security or
Securities registered in the name of the transferee (or its nominee) on the
books maintained by the Trustee. With respect to any such transfer, the Trustee
will cause, in accordance with the standing instructions and procedures existing
between the Depositary and the Trustee, the aggregate principal amount of the
Security in global form to be reduced and, following such reduction, the Company
will execute and the Trustee will authenticate and deliver to the transferee (or
such transferee's nominee, as the case may be), a Security or Securities in the
appropriate aggregate principal amount in the name of such transferee (or its
nominee) and bearing such restrictive legends as may be required by this
Indenture. In connection with any such transfer, the Trustee may request such
representations and agreements relating to the restrictions on transfer of such
Security or Securities from such transferee (or such transferee's nominee) as
the Trustee may reasonably require.

            So long as the Securities are eligible for book-entry settlement, or
unless otherwise required by law, upon any transfer of a definitive Security to
a QIB in accordance with Rule 144A, unless otherwise requested by the
transferor, and upon receipt of the definitive Security or Securities being so
transferred, together with a certification from the transferor that the
transferor reasonably believes that the transferee is a QIB (or other evidence
satisfactory to the Trustee), the Trustee shall make an endorsement on the
Restricted Global Security to reflect an increase in the aggregate principal
amount of the Securities
<PAGE>   38
                                                                              28


represented by the Restricted Global Security, the Trustee shall cancel such
definitive Security or Securities and cause, in accordance with the standing
instructions and procedures existing between the Depositary and the Trustee, the
aggregate principal amount of Securities represented by the Restricted Global
Security to be increased accordingly.

            So long as the Securities are eligible for book-entry settlement, or
unless otherwise required by law, upon any transfer of a definitive Security in
accordance with Regulation S, if requested by the transferor, and upon receipt
of the definitive Security or Securities being so transferred, together with a
certification from the transferor that the transfer was made in accordance with
Rule 903 or 904 of Regulation S or Rule 144 under the Securities Act (or other
evidence satisfactory to the Trustee), the Trustee shall make or direct the
Custodian to make, an endorsement on the Regulation S Global Security to reflect
an increase in the aggregate principal amount of the Securities represented by
the Regulation S Global Security, the Trustee shall cancel such definitive
Security or Securities and cause, or direct the Custodian to cause, in
accordance with the standing instructions and procedures existing between the
Depositary and the Custodian, the aggregate principal amount of Securities
represented by the Regulation S Global Security to be increased accordingly.

            If a holder of a beneficial interest in the Restricted Global
Security wishes at any time to exchange its interest in the Restricted Global
Security for an interest in the Regulation S Global Security, or to transfer its
interest in the Restricted Global Security to a person who wishes to take
delivery thereof in the form of an interest in the Regulation S Global Security,
such holder may, subject to the rules and procedures of the Depositary and to
the requirements set forth in the following sentence, exchange or cause the
exchange or transfer or cause the transfer of such interest for an equivalent
beneficial interest in the Regulation S Global Security. Upon receipt by the
Trustee, as transfer agent of (1) instructions given in accordance with the
Depositary's procedures from or on behalf of a holder of a beneficial interest
in the Restricted Global Security, directing the Trustee (via DWAC), as transfer
agent, to credit or cause to be credited a beneficial interest in the Regulation
S Global Security in an amount equal to the beneficial interest in the
Restricted Global Security to be exchanged or transferred, (2) a written order
given in accordance with the Depositary's procedures containing information
regarding the Euroclear or Cedel account to be credited with such increase and
the name of such account, and (3) a certificate given by the holder of such
beneficial interest stating that the exchange or transfer of such interest has
been made pursuant to and in accordance with Rule 903 or Rule 904 of Regulation
S or Rule 144 under the Securities Act (or other evidence satisfactory to the
Trustee), the Trustee, as transfer agent, shall promptly deliver appropriate
instructions to the Depositary (via DWAC), its nominee, or the custodian for the
Depositary, as the case may be, to reduce or reflect on its records a reduction
of the Restricted Global Security by the aggregate principal amount of the
beneficial interest in such Restricted Global Security to be so exchanged or
transferred from the relevant participant, and the Trustee, as transfer agent,
shall promptly deliver appropriate instructions (via DWAC) to the Depositary,
its nominee, or the custodian for the Depositary, as the case may be,
concurrently with such reduction, to increase or reflect on its records an
increase of the principal amount of such Regulation S Global Security by the
aggregate principal amount of the beneficial interest in such Restricted Global
Security to be so exchanged or transferred, and to credit or cause to be
credited to the account of the person
<PAGE>   39
                                                                              29


specified in such instructions (who may be Morgan Guaranty Trust Company of New
York, Brussels office, as operator of Euroclear or Cedel or another agent member
of Euroclear or Cedel, or both, as the case may be, acting for and on behalf of
them) a beneficial interest in such Regulation S Global Security equal to the
reduction in the principal amount of such Restricted Global Security.

            If a holder of a beneficial interest in the Regulation S Global
Security wishes at any time to exchange its interest in the Regulation S Global
Security for an interest in the Restricted Global Security, or to transfer its
interest in the Regulation S Global Security to a person who wishes to take
delivery thereof in the form of an interest in the Restricted Global Security,
such holder may, subject to the rules and procedures of Euroclear or Cedel and
the Depositary, as the case may be, and to the requirements set forth in the
following sentence, exchange or cause the exchange or transfer or cause the
transfer of such interest for an equivalent beneficial interest in such
Restricted Global Security. Upon receipt by the Trustee, as transfer agent of
(l) instructions given in accordance with the procedures of Euroclear or Cedel
and the Depositary, as the case may be, from or on behalf of a beneficial owner
of an interest in the Regulation S Global Security directing the Trustee, as
transfer agent, to credit or cause to be credited a beneficial interest in the
Restricted Global Security in an amount equal to the beneficial interest in the
Regulation S Global Security to be exchanged or transferred, (2) a written order
given in accordance with the procedures of Euroclear or Cedel and the
Depositary, as the case may be, containing information regarding the account
with the Depositary to be credited with such increase and the name of such
account, and (3) prior to the expiration of the related Restricted Period, a
certificate given by the holder of such beneficial interest and stating that the
person transferring such interest in such Regulation S Global Security
reasonably believes that the person acquiring such interest in the Restricted
Global Security is a QIB and is obtaining such beneficial interest in a
transaction meeting the requirements of Rule 144A and any applicable securities
laws of any state of the United States or any other jurisdiction (or other
evidence satisfactory to the Trustee), the Trustee, as transfer agent, shall
promptly deliver (via DWAC) appropriate instructions to the Depositary, its
nominee, or the custodian for the Depositary, as the case may be, to reduce or
reflect on its records a reduction of the Regulation S Global Security by the
aggregate principal amount of the beneficial interest in such Regulation S
Global Security to be exchanged or transferred, and the Trustee, as transfer
agent, shall promptly deliver (via DWAC) appropriate instructions to the
Depositary, its nominee, or the custodian for the Depositary, as the case may
be, concurrently with such reduction, to increase or reflect on its records an
increase of the principal amount of the Restricted Global Security by the
aggregate principal amount of the beneficial interest in the Regulation S Global
Security to be so exchanged or transferred, and to credit or cause to be
credited to the account of the person specified in such instructions a
beneficial interest in the Restricted Global Security equal to the reduction in
the principal amount of the Regulation S Global Security. After the expiration
of the related Restricted Period, the certification requirement set forth in
clause (3) of the second sentence of the above paragraph will no longer apply to
such exchanges and transfers.

            If a holder of a definitive Security wishes at any time to exchange
its Security for a beneficial interest in any Global Security (or vice versa),
or to transfer its definitive Security to a person who wishes to take delivery
thereof in the form of a beneficial interest in
<PAGE>   40
                                                                              30


a Global Security (or vice versa), such Securities and beneficial interests may
be exchanged or transferred for one another only in accordance with such
procedures as are substantially consistent with the provisions of the two
preceding paragraphs (including the certification requirements intended to
ensure that such exchanges or transfers comply with Rule 144, Rule 144A or
Regulation S, as the case may be) and as may be from time to time adopted by the
Company and the Trustee.

            Any beneficial interest in one of the Global Securities that is
transferred to a person who takes delivery in the form of an interest in the
other Global Security will, upon transfer, cease to be an interest in such
Global Security and become an interest in the other Global Security and,
accordingly, will thereafter be subject to all transfer restrictions and other
procedures applicable to beneficial interests in such other Global Security for
as long as it remains such an interest.

            For each Closing Date, prior to or on the 40th day after the later
of the commencement of the offering of the Capital Securities issued in
connection with such Closing Date and such Closing Date (each such period a
"Restricted Period"), beneficial interests in a Regulation S Global Security
issued in connection with such Closing Date may only be held through Morgan
Guaranty Trust Company of New York, Brussels Office, as operator of Euroclear or
Cedel or another agent member of Euroclear and Cedel acting for and on behalf of
them, unless delivery is made through a Restricted Global Security in accordance
with the certification requirements hereof. During a Restricted Period,
interests in the Regulation S Global Security, if any, issued in connection with
the Closing Date related to such Restricted Period, may be exchanged for
interests in a Restricted Global Security or for definitive Securities only in
accordance with the certification requirements described above.

respect to the Outstanding Securities as provided in this Section on and after
the date the conditions set forth in Section 404 are satisfied (hereinafter
called "Covenant Defeasance"), and the Trustee, at the cost and expense of the
Company, shall execute proper instruments acknowledging the same. For this
purpose, such Covenant Defeasance means that the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation set
forth in any such covenant (to the extent so specified in the case of Section
501(3)), whether directly or indirectly by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant

effect that, and such opinion shall confirm that, the Holders of the Securities

Defeasance had not occurred;

            (d) such Legal Defeasance or Covenant Defeasance will not result in
a breach or violation of, or constitute a default under, any agreement or
instrument to which the Company is a party or by which it is bound; and

            (2) failure to pay any principal on the Securities when due, whether
at Stated Maturity, upon redemption, by declaration of acceleration or

            (3) failure to observe or perform in any material respect any other

Company, or ordering the winding up or liquidation of its affairs, and the
continuance of any such decree or order for relief or any such other decree or
order unstayed and in effect for a period of 90 consecutive days; or

            (5) (A) the commencement by the Company of a voluntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or of any other case or proceeding to be
adjudicated a bankrupt or insolvent, or (B) the consent by the Company to the
entry of a decree or order for relief in respect of itself in an involuntary
case or proceeding under any applicable Federal or State bankruptcy, insolvency,

the making by the Company of an assignment for the benefit of creditors.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

            If an Event of Default occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Outstanding Securities shall have the right to declare the
principal of and the interest on all the Securities and any other amounts
payable hereunder to be due and payable immediately, provided, however, that if
upon an Event of Default, the Trustee or the Holders of at least 25% in
aggregate principal amount of the Outstanding Securities fail to declare the
payment of all amounts on the Securities to be immediately due and payable, the
holders of at least 25% in aggregate liquidation amount of Capital Securities
then outstanding shall have such right, by a notice in writing to the Company
(and to the Trustee if given by Holders or the holders of Capital Securities)
and upon any such declaration such principal and all accrued interest shall
become immediately due and payable.
<PAGE>   45
                                                                              35


            At any time after such a declaration of acceleration has been made
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter provided in this Article, the Holders of a
majority in aggregate principal amount of the Outstanding Securities, by written
notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if (1) the Company has paid or deposited with the Trustee a
sum sufficient to pay (A) all overdue interest on all Securities, (B) the
principal of (and premium, if any, on) any Securities which have become due
otherwise than by such declaration of acceleration and interest thereon at the
rate borne by the Securities, (C) to the extent that payment of such interest is
lawful, interest upon overdue interest at the rate borne by the Securities, and
(D) all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel; and (2) all Events of Default, other than the non-payment of the
principal of Securities which have become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 513. Should the
Holders of such Securities fail to annul such declaration and waive such
default, the holders of a majority in aggregate liquidation amount of the
Capital Securities then outstanding shall have such right. No such rescission
shall affect any subsequent default or impair any right consequent thereon.

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee

            The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest, and, to the extent that payment thereof
shall be legally enforceable, interest on any overdue principal and on any
overdue 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 the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

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

                                                                              36


SECTION 504. Trustee May File Proofs of Claim.

            In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other similar judicial
proceeding relative to the Company (or any other obligor upon the Securities),
its property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding. In particular, the Trustee shall
be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607. No provision of this Indenture shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

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

SECTION 506. Application of Money Collected.

            Subject to Article Eleven, any money collected by the Trustee
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on
account of principal, upon presentation of the Securities and the notation
thereon of the payment, if only partially paid, and upon surrender thereof, if
fully paid;

            FIRST: To the payment of all amounts due the Trustee under Section
607; and

            SECOND: To the payment of the amounts then due and unpaid for
principal of and interest on the Securities in respect of which or for the
benefit of which such money has been collected, ratably, without preference or
priority of any kind, according to the amounts due and payable as such
Securities for principal and interest, respectively.

                                                                              37


            THIRD: To the Company, if any balance shall remain.

SECTION 507. Limitation on Suits.

            No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

            (1) such Holder has previously given written notice to the Trustee
of a continuing Event of Default;

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

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

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

            (5) no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities; it being understood and intended
that no one or more Holders 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 Holders, or to obtain or to seek to obtain
priority or preference over any other Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all the Holders.

SECTION 508. Unconditional Right of Holders to Receive Principal and Interest;
             Capital Security Holders' Rights.

            Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and (subject to Section 307) interest on
such Security on the Stated Maturity expressed in such Security (or, in the case
of redemption, on the Redemption Date) and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent
of such Holder.

            If an Event of Default constituting the failure to pay interest or
principal on the Securities on the date such interest or principal is otherwise
payable has occurred and is continuing, then a holder of Capital Securities may
directly institute a proceeding for enforcement of payment to such holder
directly of the principal of or interest on the Securities having a principal
amount equal to the aggregate liquidation amount of the Capital Securities
<PAGE>   48
                                                                              38


as such holder on or after the respective due date specified in the Securities.
The Company may not amend this Section without the prior written consent of the
holders of all of the Capital Securities. Notwithstanding any payment made to
such holder of Capital Securities by the Company in connection with such a
Direct Action, the Company shall remain obligated to pay the principal of or
interest on the Securities held by the Trust or the Property Trustee and the
Company 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 Company to such holder in any Direct Action. A holder
of Capital Securities will not be able to exercise directly any other remedy
available to the Holders of the Securities.

SECTION 509. Restoration of Rights and Remedies.

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

SECTION 510. Rights and Remedies Cumulative.

            Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511. Delay or Omission not Waiver.

            No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.
<PAGE>   49
                                                                              39


SECTION 512. Control by Holders.

            The Holders of a majority in principal amount of the Outstanding
Securities 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 that

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

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

SECTION 513. Waiver of Past Defaults.

            Subject to Sections 902 and 1008 hereof, the Holders of not less
than a majority in principal amount of the Outstanding Securities may on behalf
of the Holders of all the Securities waive any past default hereunder and its
consequences, except a default

            (1) in the payment of the principal of or interest on any Security
(unless such default has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Trustee); or

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

provided, however, that such waiver or modification to such waiver shall not be
effective until the holders of a majority in liquidation preference of Capital
Securities shall have consented to such waiver or modification to such waiver;
provided further, that if the consent of the Holder of each of the Outstanding
Securities is required, such waiver shall not be effective until each holder of
the Capital Securities shall have consented to such waiver.

            Upon any such waiver, such default shall cease to exist, effective
as of the date specified in such waiver (and effective retroactively to the date
of default, if so specified) and any Event of Default arising therefrom shall be
deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

SECTION 514. Undertaking for Costs.

            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, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust
<PAGE>   50
                                                                              40


Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or the Trustee or in any suit for the enforcement of the right to receive the
principal of and interest on any Security.

SECTION 515. Waiver of Stay or Extension Laws.

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


                                   ARTICLE SIX

                                     TRUSTEE

SECTION 601. Certain Duties and Responsibilities.

            The duties and responsibilities of the Trustee shall be as provided
by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 602. Notice of Defaults.

            The Trustee shall give the Holders notice of any default hereunder
as and to the extent provided by the Trust Indenture Act; provided, however,
that except in the case of a default in the payment of the principal of or
interest on any Security, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the interests of the
Holders of Securities; provided, further, that in the case of any default of the
character specified in Section 501(3), no such notice to Holders shall be given
until at least 30 days after the occurrence thereof. For the purpose of this
Section, the term "default" means any event which is, or after notice or lapse
of time or both would become, an Event of Default. For purposes of this Section,
the Trustee shall not be deemed to have knowledge of a default
<PAGE>   51
                                                                              41


unless the Trustee has actual knowledge of such default or has received written
notice of such default in the manner contemplated by Section 105.

SECTION 603. Certain Rights of Trustee.

            Subject to the provisions of Section 601:

            (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, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it
to be genuine and to have been signed or presented by the proper party or
parties;

                                    COVENANTS

SECTION 1001. Payment of Principal and Interest.

            The Company will duly and punctually pay the principal of and
interest on the Securities in accordance with the terms of the Securities and
this Indenture and comply with all other terms and conditions and agreements
contained herein.

SECTION 1002. Maintenance of Office or Agency.

            The Company will maintain in The City of New York an office or
agency where Securities may be presented or surrendered for registration of
transfer or exchange, where Securities may be surrendered for conversion and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The Company will give prompt written notice to
the Trustee of the location, and any change in location, of such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

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

SECTION 1003. Money for Security Payments to be Held in Trust.

            If the Company shall at any time act as its own Paying Agent, it
will, on, or at the option of the Company, before each due date of the principal
of or interest on any of the
<PAGE>   62
                                                                              52


Securities, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act. In such case the Company shall not invest the amount so segregated and held
in trust pending the distribution thereof.

            Whenever the Company shall have one or more Paying Agents, it will,
on or prior to each due date of the principal of or interest on any Securities,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act; provided, however, that any such deposit on a due date shall
be initiated prior to 12:00 noon (New York time) in same-day funds.

            The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will (i) comply with the provisions of the Trust Indenture Act
applicable to it as a Paying Agent and (ii) during the continuance of any
default by the Company (or any other obligor upon the Securities) in the making
of any payment in respect of the Securities, upon the written request of the
Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent as such.

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

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal or interest that
has become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease.

SECTION 1004. Statements by Officers as to Default.

            The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof the Company is in default in the performance and observance of
any of the material terms, provisions and conditions of this Indenture (without
regard to any period of grace or requirement of notice provided hereunder) and,
if the Company shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge.

SECTION 1005. Existence.

            Subject to Article Eight, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders and, while
any Capital Securities are outstanding, the holders of the Capital Securities.

SECTION 1006. Maintenance of Properties.

            The Company will cause all properties used or useful in the conduct
of its business or the business of any Subsidiary to be maintained and kept in
good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.

SECTION 1007. Payment of Taxes and Other Claims.

            The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company or any Subsidiary that
comprise more than 10% of the assets of the Company and its Subsidiaries, taken
as a whole; provided, however, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings.

SECTION 1008. Waiver of Certain Covenants.

            Except as otherwise specified or as contemplated by Section 301 for
Securities, the Company may, with respect to the Securities, omit in any
particular instance to comply with any term, provision or condition set forth in
any covenant provided pursuant to Section 901(2) for the benefit of the Holders
if before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Securities shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become
<PAGE>   64
                                                                              54


effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

SECTION 1009. Payment of the Trust's Costs and Expenses.

            Since the Trust is being formed solely to facilitate an investment
in the Securities, the Company, as borrower, hereby covenants to pay all debts
and obligations (other than with respect to the Capital Securities and Common
Securities) and all costs and expenses of the Trust (including, but not limited
to, all costs and expenses relating to the organization of the Trust, the fees
and expenses of the trustees of the Trust and all costs and expenses relating to
the operation of the Trust) and to pay any and all taxes, duties, assessments or
governmental charges of whatever nature (other than withholding taxes) imposed
on the Trust by the United States, or any other taxing authority, so that the
net amounts received and retained by the Trust and the Property Trustee after
paying such expenses will be equal to the amounts the Trust and the Property
Trustee would have received had no such costs or expenses been incurred by or
imposed on the Trust. The foregoing obligations of the Company are for the
benefit of, and shall be enforceable by, any person to whom any such debts,
obligations, costs, expenses and taxes are owed (each, a "Creditor") whether or
not such Creditor has received notice thereof. Any such Creditor may enforce
such obligations of the Company directly against the Company, and the Company
irrevocably waives any right or remedy to require that any such Creditor take
any action against the Trust or any other person before proceeding against the
Company. The Company shall execute such additional agreements as may be
necessary or desirable to give full effect to the foregoing.

SECTION 1010. Restrictions on Payments and Distributions.

            The Company will not, and will not permit any Subsidiary to, (i)
declare or pay any dividends or distributions on, or redeem, purchase, acquire,
or make a liquidation payment with respect to, any of the Company's capital
stock or (ii) make any payment of principal, interest or premium, if any, on or
repay or repurchase or redeem any debt securities of the Company that rank pari
passu with or junior in interest to the Securities or make any guarantee
payments with respect to any guarantee by the Company of the debt securities of
any Subsidiary if such guarantee ranks pari passu with or junior in interest to
the Securities, (other than (a) repurchases, redemptions or other acquisitions
of shares of capital stock of the Company in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of
any one or more employees, officers, directors or consultants or in connection
with a dividend reinvestment or stockholder stock purchase plan, (b) as a result
of an exchange or conversion of any class or series of the Company's capital
stock (or any capital stock of a subsidiary of the Company) for any class or
series of the Company's capital stock or of any class or series of the Company's
indebtedness for any class or series of the Company's capital stock, (c) the
purchase of fractional interests in shares of the Company's capital stock
pursuant to the conversion or exchange provisions of such capital stock or the
security being converted or exchanged, (d) any declaration of a dividend in
connection with the adoption of any stockholder's rights plan, or the issuance
of rights, stock or other property under any stockholder's rights plan, or the
redemption or
<PAGE>   65
                                                                              55


repurchase of rights pursuant thereto, or (e) any dividend in the form of stock,
warrants, options or other rights where the dividend stock or the stock issuable
upon exercise of such warrants, options or other rights is the same stock as
that on which the dividend is being paid or ranks pari passu with or junior to
such stock) if at such time (x) there shall have occurred any event of which the
Company has actual knowledge that (I) with the giving of notice or the lapse of
time, or both, would constitute an Event of Default and (II) in respect of which
the Company shall not have taken reasonable steps to cure, (y) the Company shall
be in default with respect to its payment of any obligations under the Guarantee
or (z) the Company shall have given notice of its election of an Extension
Period as provided herein and shall not have rescinded such notice, or such
Extension Period, or any extension thereof, shall be continuing.


                                 ARTICLE ELEVEN

                           SUBORDINATION OF SECURITIES

SECTION 1101. Securities Subordinate to Indebtedness.

            The Company covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article (subject to Article Four),
the payment of the principal of and interest on each and all of the Securities
are hereby expressly made subordinate and subject in right of payment to the
prior payment in full of all Indebtedness.

            The provisions of this Article Eleven are made for the benefit of
the holders of Indebtedness and such holders are made obligees hereunder and any
one or more of them may enforce such provisions. Holders of Indebtedness need
not prove reliance on the subordination provisions hereof.

SECTION 1102. Default on Indebtedness.

            In the event and during the continuation of any default in the
payment of principal, premium, interest or any other payment due on any
Indebtedness, or in the event that any event of default with respect to any
Indebtedness shall have occurred and be continuing and shall have resulted in
such Indebtedness becoming or being declared due and payable prior to the date
on which it would otherwise have become due and payable (unless and until such
event of default shall have been cured or waived or shall have ceased to exist
and such acceleration shall have been rescinded or annulled) or in the event any
judicial proceeding shall be pending with respect to any such default in payment
or such event of default, then no payment shall be made by the Company with
respect to the principal (including redemption payments) of, or interest on, the
Securities.

            In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee or any Holder when such payment is prohibited by the
preceding paragraph of this Section 1102, such payment shall be held in trust
for the benefit of, and shall be paid
<PAGE>   66
                                                                              56


over or delivered to, the holders of Indebtedness or their respective
representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Indebtedness may have been issued, as their respective
interests may appear, but only to the extent that the holders of the
Indebtedness (or their representative or representatives or a trustee) notify
the Trustee within 90 days of such payment of the amounts then due and owing on
the Indebtedness and only the amounts specified in such notice to the Trustee
shall be paid to the holders of Indebtedness; provided, however, that holders of
Indebtedness shall not be entitled to receive payment of any such amounts to the
extent that such holders would be required by the subordination provisions of
such Indebtedness to pay such amounts over to the obligees on trade accounts
payable or other liabilities arising in the ordinary course of the Company's
business.

SECTION 1103. Prior Payment of Indebtedness Upon Acceleration of Securities.

            In the event that the Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of the Indebtedness
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all amounts then due on or in respect of
such Indebtedness (including any amounts due upon acceleration), or provision
shall be made for such payment in cash or cash equivalents or otherwise in a
manner satisfactory to the holders of such Indebtedness, before the Holders of
the Securities are entitled to receive any payment or distribution of any kind
or character, whether in cash, properties or securities, by the Company on
account of the principal of or interest on the Securities or on account of the
purchase or other acquisition of Securities by the Company or any Subsidiary;
provided, however, that holders of Indebtedness shall not be entitled to receive
payment of any such amounts to the extent that such holders would be required by
the subordination provisions of such Indebtedness to pay such amounts over to
the obligees on trade accounts payable or other liabilities arising in the
ordinary course of the Company's business.

            In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee or any Holder when such payment is prohibited by the
preceding paragraph of this Section 1103, such payment shall be held in trust
for the benefit of, and shall be paid over or delivered to, the holders of
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Indebtedness may have been
issued, as their respective interests may appear, but only to the extent that
the holders of the Indebtedness (or their representative or representatives or a
trustee) notify the Trustee within 90 days of such payment of the amounts then
due and owing on the Indebtedness and only the amounts specified in such notice
to the Trustee shall be paid to the holders of Indebtedness.

SECTION 1104. Liquidation; Dissolution; Bankruptcy.

            Upon any payment by the Company, or distribution of assets of the
Company 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 Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all principal of,
<PAGE>   67
                                                                              57


and premium, if any, and interest due or to become due upon all Indebtedness
(including interest after the commencement of any bankruptcy, insolvency,
receivership or other proceedings at the rate specified in the applicable
Indebtedness, whether or not such interest is an allowable claim in any such
proceeding) shall first be paid in full, or payment thereof provided for in
accordance with its terms, before any payment is made on account of the
principal or interest on the Securities; and upon any such dissolution or
winding-up or liquidation or reorganization any payment by the Company, or
distribution of substantially all of the assets of the Company of any kind or
character, whether in cash, property or securities, to which the Holders of the
Securities or the Trustee would be entitled, except for the provisions of this
Article Eleven, shall be paid by the Company or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Holders of the Securities or by the Trustee under this
Indenture if received by them or it, directly to the holders of Indebtedness
(pro rata to such holders on the basis of the respective amounts of Indebtedness
held by such holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Indebtedness may have been issued, as their
respective interests may appear, to the extent necessary to pay all Indebtedness
in full (including interest after the commencement of any bankruptcy,
insolvency, receivership or other proceedings at the rate specified in the
applicable Indebtedness, whether or not such interest is in an allowable claim
in any such proceeding) or to provide for such payment in accordance with its
terms, after giving effect to any concurrent payment or distribution to or for
the holders of Indebtedness, before any payment or distribution is made to the
Holders of Securities or to the Trustee or the Property Trustee on behalf of the
Holders of Capital Securities; provided, however, that such holders of
Indebtedness shall not be entitled to receive payment of any such amounts to the
extent that such holders would be required by the subordination provisions of
such Indebtedness to pay such amounts over to the obligees on trade accounts
payable or other liabilities arising in the ordinary course of the Company's
business.

            In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee or the Holders of the Securities before all Indebtedness is paid in full
(including interest after commencement of any bankruptcy, insolvency,
receivership or other proceedings at the rate specified in the applicable
Indebtedness, whether or not such interest is an allowable claim in any such
proceeding), or provision is made for such payment 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 Indebtedness or their representative
or representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments evidencing any Indebtedness may have been issued, as
their respective interests may appear, as calculated by the Company, for
application to the payment of all Indebtedness remaining unpaid to the extent
necessary to pay all Indebtedness in full in accordance with its terms, after
giving effect to any concurrent payment or distribution to or for the holders of
such Indebtedness.
<PAGE>   68
                                                                              58


            Any holder of Indebtedness may file any proof of claim or similar
instrument on behalf of the Trustee and the Holders if such instrument has not
been filed by the date which is 30 days prior to the date specified for filing
thereof.

            For purposes of this Article Eleven, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Eleven with
respect to the Securities to the payment of all Indebtedness that may at the
time be outstanding, provided, however, that (i) the Indebtedness is assumed by
the new corporation, if any, resulting from any such reorganization or
readjustment, and (ii) the rights of the holders of the Indebtedness are not,
without the consent of such holders, altered by such reorganization or
readjustment. The consolidation of the Company with, or merger of the Company
into, another corporation or the liquidation or dissolution of the Company
following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another corporation upon the terms and
conditions provided for in Article Eight hereof shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 1104 if such other corporation shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article
Eight hereof. Nothing in Section 1103 or in this Section 1104 shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 607.

SECTION 1105. Subrogation.

            Subject to the payment of all Indebtedness to the extent provided in
Sections 1103 and 1104 of this Indenture, the rights of the Holders of the
Securities shall be subrogated to the rights of the holders of Indebtedness to
receive payments or distributions of cash, property or securities of the Company
applicable to the 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 the Indebtedness of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article Eleven,
shall, as between the Company, its creditors other than holders of Indebtedness,
and the Holders of the Securities, be deemed to be a payment by the Company to
or on account of the Indebtedness. It is understood that the provisions of this
Article Eleven 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 the Indebtedness on the other hand.

            Nothing contained in this Article Eleven or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as between the
Company, its creditors other than the holders of Indebtedness, and the Holders
of the Securities, the obligation of the Company, 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 Company other than the holders of the Indebtedness, nor shall anything
herein or therein prevent the Trustee or the Holder of any
<PAGE>   69
                                                                              59


Security from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article
Eleven of the holders of Indebtedness in respect of cash, property or securities
of the Company received upon the exercise of any such remedy.

            Upon any payment or distribution of assets of the Company referred
to in this Article Eleven, the Trustee, subject to the provisions of Section
601, and the Holders of the Securities, shall be entitled to rely upon any order
or decree made by any court of competent jurisdiction in which such dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent
or other Person making such payment or distribution, delivered to the Trustee or
to the Holders of the Securities, for the purposes of ascertaining the Persons
entitled to participate in such distribution, the holders of the Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Eleven.

SECTION 1106. Trustee to Effectuate Subordination.

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

SECTION 1107. Notice by the Company.

            The Company shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Company 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 Eleven. Notwithstanding
the provisions of this Article Eleven 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 Eleven,
unless and until a Responsible Officer of the Trustee shall have received
written notice thereof at the Corporate Trust Office of the Trustee from the
Company or a holder or holders of Indebtedness or from any trustee therefor; and
before the receipt of any such written notice, the Trustee, subject to the
provisions of Section 601, 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 1107 at least three Business Days prior
to the date 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), then, anything herein contained
to the contrary notwithstanding, the Trustee shall have full power and authority
to receive such money 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 three Business Days prior to such date.

                                                                              60


            The Trustee, subject to the provisions of Section 601, shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Indebtedness (or a trustee on behalf of
such holder) to establish that such notice has been given by a holder of
Indebtedness or a trustee on behalf of any such holder or holders. In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Indebtedness to participate in
any payment or distribution pursuant to this Article Eleven, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of 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
Eleven, and if such evidence is not furnished the Trustee may defer any payment
to such Person pending judicial determination as to the right of such Person to
receive such payment.

SECTION 1108. Rights of the Trustee; Holders of Indebtedness.

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

            With respect to the holders of Indebtedness, the Trustee undertakes
to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Eleven, and no implied covenants or
obligations with respect to the holders of 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 Indebtedness and, subject to the provisions of
Section 601, the Trustee shall not be liable to any holder of Indebtedness if it
shall pay over or deliver to holders of Securities, the Company or any other
Person money or assets to which any holder of Indebtedness shall be entitled by
virtue of this Article Eleven or otherwise.

SECTION 1109. Subordination May Not Be Impaired.

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

            Without in any way limiting the generality of the foregoing
paragraph, the holders of Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
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,
Indebtedness or otherwise

                                                                              61


amend or supplement in any manner Indebtedness or any instrument evidencing the
same or any agreement under which Indebtedness is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Indebtedness; (iii) release any Person liable in any manner
for the collection of Indebtedness; and (iv) exercise or refrain from exercising
any rights against the Company and any other Person.


                                 ARTICLE TWELVE

                            REDEMPTION OF SECURITIES

SECTION 1201. Optional Redemption; Conditions to Optional Redemption.

            At any time on or after June 15, 2007, the Company shall have the
right, subject to the last paragraph of this Section 1201 and to the receipt of
any necessary prior approval of the Federal Reserve, to redeem the Securities,
in whole or in part, from time to time, at a Redemption Price equal to 100% of
the principal amount of Securities to be redeemed plus any accrued but unpaid
interest (including any Additional Interest) to the Redemption Date.

            If a Special Event shall occur and be continuing, the Company shall
have the right, subject to the last paragraph of this Section 1201 and to the
receipt of any necessary prior approval of the Federal Reserve, to redeem, upon
not less than 30 days nor more than 60 days notice, the Securities in whole, but
not in part, at a Redemption Price equal to 100% of the principal amount of
Securities then outstanding plus accrued but unpaid interest (including any
Additional Interest) to the Redemption Date.

            For so long as the Trust is the Holder of all Securities
Outstanding, the proceeds of any redemption described in this Section 1201 shall
be used by the Trust to redeem Common Securities and Capital Securities in
accordance with their terms. The Company shall not redeem the Securities in part
unless all accrued and unpaid interest (including any Additional Interest) has
been paid in full on all Securities outstanding for all quarterly interest
periods terminating on or prior to the Redemption Date.

SECTION 1202. Applicability of Article.

            Redemption of Securities at the election of the Company, as
permitted by Section 1201, shall be made in accordance with such provision and
this Article.

SECTION 1203. Election to Redeem; Notice to Trustee.

            The election of the Company to redeem Securities pursuant to Section
1201 shall be evidenced by a Board Resolution. In case of any redemption at the
election of the Company, the Company shall, at least 45 days and no more than 60
days prior to the Redemption Date fixed by the Company, notify the Trustee of
such Redemption Date and of
<PAGE>   72
                                                                              62


the principal amount of Securities to be redeemed and provide a copy of the
notice of redemption given to Holders of Securities to be redeemed pursuant to
Section 1205.

SECTION 1204. Selection by Trustee of Securities to be Redeemed.

            If less than all the Securities are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be
redeemed shall be selected by lot (or such other method of selection as the
Trustee may customarily employ) not more than 60 days prior to the Redemption
Date by the Trustee, from the Outstanding Securities not previously called for
redemption.

            The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to be
redeemed.

            The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

            For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1205. Notice of Redemption.

            Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 (provided that the Trustee shall itself have
received notice not less than 45 days prior to the Redemption Date) nor more
than 60 days prior to the Redemption Date, to each Holder of Securities to be
redeemed, at his address appearing in the Security Register.

            All notices of redemption shall identify the Securities to be
redeemed (including CUSIP number) and shall state:

            (1) the Redemption Date,

            (2) the Redemption Price,

            (3) that on the Redemption Date the Redemption Price will become due
and payable upon each such Security to be redeemed and that interest thereon
will cease to accrue on and after said date, and

            (4) the place or places where such Securities are to be surrendered
for payment of the Redemption Price.
<PAGE>   73
                                                                              63


            Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1206. Deposit of Redemption Price.

            On or prior to any Redemption Date, the Company shall deposit with
the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest (including
any Additional Interest) on, all the Securities which are to be redeemed on that
date; provided, however, that any such deposit on a Redemption Date shall be
initiated prior to 12:00 noon (New York time) in same-day funds.

SECTION 1207. Securities Payable on Redemption Date.

            Notice of redemption having been given as aforesaid, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest (including any Additional Interest)) such Securities shall cease to
bear interest. Upon surrender of any such Security for redemption in accordance
with said notice, such Security shall be paid by the Company at the Redemption
Price, together with accrued interest to the Redemption Date; provided, however,
that installments of interest whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

            If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid, bear interest
from the Redemption Date at the rate borne by the Security.

SECTION 1208. Securities Redeemed in Part.

            Any Security which is to be redeemed only in part shall be
surrendered at a place of payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder
therefor or his attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.

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

be duly executed, all as of the day and year first above written.

                  STAR BANC CORPORATION, a corporation duly organized and
existing under the laws of the State of Ohio (herein called the "Company", which
term includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to The First National Bank of
Chicago, as Trustee, or registered assigns, the principal sum of
____________________ ($________) on June 15, 2027, and to pay interest on said
principal sum from June 8, 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, quarterly (subject to deferral as set forth herein) in
arrears on the 15th day of June, September, December and March of each year,
commencing September 15, 1997, at a variable per annum rate equal to LIBOR (as
defined in the Indenture) plus 0.765% until the principal hereof shall have
become due and payable (plus Additional Interest, if any), and on any overdue
principal 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. The amount of interest payable for any
period will be computed on the actual number of days elapsed and a year of 360
days. The amount of interest payable for any period shorter than a full
quarterly period for which interest is computed, will be computed on the basis
of actual number of days elapsed in such 90-day period. In the event that any
date on which interest is payable on this Security is not a Business Day, then a
payment of the interest payable on such date will be made on the next succeeding
day which is a Business Day (and without any interest or other payment in
respect of any such delay), with the same force and effect as if made on the
date the payment was originally payable. A "Business Day" shall mean any day
other than a Saturday or a Sunday or a day on which banking institutions in the
New York City, Chicago, Illinois or Cincinnati, Ohio are authorized or required
by law or executive order to remain closed or a day on which the Corporate Trust
Office of the Trustee, or the principal office of the Property Trustee under the
Declaration, is closed for business. The interest installment so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name the Securities
(or one or more Predecessor Securities, as defined in the Indenture) is
registered at the close of business on the Regular Record Date for such interest
installment, which shall be the 1st day of the month in which such Interest
Payment Date occurs. Any such interest installment not so punctually paid or
duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name the
Securities for one or more Predecessor Securities is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
not less than 10 days prior to such Special Record Date, or be paid at any time
in



<PAGE>   76






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 said Indenture.

                  The Company shall have the right at any time during the term
of this Security, from time to time, to defer payment of interest on such
Security for up to 20 quarterly periods (an "Extension Period"), provided that
no Extension Period may extend past the Stated Maturity of this Security. There
may be multiple Extension Periods of varying lengths during the term of this
Security. At the end of each Extension Period, if any, the Company shall pay all
interest then accrued and unpaid, together with interest thereon, compounded
quarterly at the rate specified on this Security to the extent permitted by
applicable law. During any such Extension Period, the Company may not, and may
not permit any subsidiary of the Company to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock or (ii) make any payment of
principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities of the Company that rank pari passu with or junior in interest
to the Securities or make any guarantee payments with respect to any guarantee
by the Company of the debt securities of any subsidiary of the Company if such
guarantee ranks pari passu or junior in interest to the Securities (other than
(a) repurchases, redemptions or other acquisitions of shares of capital stock of
the Company in connection with any employment contract, benefit plan or other
similar arrangement with or for the benefit of any one or more employees,
officers, directors or consultants or in connection with a dividend reinvestment
or stockholder stock purchase plan, (b) as a result of an exchange or conversion
of any class or series of the Company's capital stock (or any capital stock of a
subsidiary of the Company) for any class or series of the Company's capital
stock or of any class or series of the Company's indebtedness for any class or
series of the Company's capital stock, (c) the purchase of fractional interests
in shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
(d) any declaration of a dividend in connection with the adoption of any
stockholder's rights plan, or the issuance of rights, stock or other property
under any stockholder's rights plan, or the redemption or repurchase of rights
pursuant thereto, or (e) any dividend in the form of stock, warrants, options or
other rights where the dividend stock or the stock issuable upon the exercise of
such warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock). Prior
to the termination of any such Extension Period, the Company may further extend
the interest payment period, provided that no Extension Period may exceed 20
consecutive quarterly periods or extend beyond the Stated Maturity of the
Securities. Upon the termination of any such Extension Period and the payment of
all amounts then due on any Interest Payment Date, the Company may elect to
begin a new Extension Period subject to the above requirements. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Company shall give the Trustee notice of its election of such Extension
Period at least one Business Day prior to the record date for the related
interest payment.

                  Payment of the principal of and interest on this Security will
be made at the office or agency of the Paying Agent maintained for that purpose
in the United States, in such coin or currency of the United States of America
as at the time of payment is legal tender for

                                       -2-


<PAGE>   77






payment of public and private debts; provided, however, that at the option of
the Company, payment of interest may be made (i) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Security
Register or (ii) by wire transfer in immediately available funds at such place
and to such account as may be designated by the Person entitled thereto as
specified in the Security Register.

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

                  In addition, each Holder hereof, by such Holder's acceptance
hereof, agrees to treat the Junior Subordinated Debentures evidenced hereby as
indebtedness of the Company for all United States tax purposes.

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

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

                          [Form of Reverse of Security]

                  This Security is one of a duly authorized issue of Securities
of Star Banc Corporation (the "Company"), designated as its Floating Rate Junior
Subordinated Debentures due 2027 (herein called the "Securities"), issued under
an Indenture, dated as of June 8, 1997 (herein called the "Indenture"), between
the Company and The First National Bank of Chicago, a national banking
association, as Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Trustee,
the Company and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered.

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

                  At any time on or after June 15, 2007, the Company shall have
the right, subject to the terms and conditions of Article Twelve of the
Indenture, to redeem this Security at the option of the Company, in whole or in
part, at a Redemption Price equal to the principal amount so redeemed plus
accrued but unpaid interest (including any Additional Interest) to the
Redemption Date.

                  If a Special Event as defined in Article Twelve of the
Indenture shall occur and be continuing, the Company shall have the right,
subject to the terms and conditions of Article Twelve of the Indenture, to
redeem this Security at the option of the Company, without premium or penalty,
in whole but not in part, at a Redemption Price equal to 100% of the principal
amount so redeemed plus accrued but unpaid interest (including any Additional
Interest) to the Redemption Date. Any redemption pursuant to this paragraph will
be made upon not less than 30 nor more than 60 days notice, at the Redemption
Price. If the Securities are only partially redeemed by the Company, the
Securities will be redeemed by lot (or such other method of selection as the
Trustee may customarily employ). 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.

                  If an Event of Default with respect to the Securities shall
occur and be continuing, the principal of the Securities may be declared due and
payable in the manner, with the effect and subject to the conditions provided in
the Indenture.

                  The Indenture contains provisions for satisfaction and
discharge or legal defeasance of the entire indebtedness of this Security and
for the defeasance of certain covenants under the Indenture at any time upon
compliance by the Company with certain conditions set forth in the Indenture.

                  The Indenture contains provisions permitting the Company and
the Trustee, with the consent of Holders of not less than a majority in
principal amount of the Outstanding Securities affected by such modification, to
modify the Indenture in a manner affecting the rights of the Holders of the
Securities; provided that no such modification may, without the

                                       -5-


<PAGE>   80






consent of the Holder of each Outstanding Security affected thereby, (i) change
the maturity of the principal of, or any installment of interest on, such
Security or reduce the principal amount thereof, or the rate of payment of
interest thereon, or extend the time of payment of interest thereon (except such
extensions as are provided for in such Security), or change the place of payment
where, or the coin or currency in which, such Security or interest thereon is
payable, or impair the right to institute suit for the enforcement of such
payment on or after the Maturity thereof (or, in the case of redemption, on or
after the Redemption Date), or modify the provisions of the Indenture with
respect to the subordination of the Securities in a manner adverse to the
Holders, (ii) reduce the percentage in principal amount of the Outstanding
Securities, the consent of whose Holders is required for such supplemental
Indenture or the consent of whose Holders is required for any waiver of
compliance with certain provisions of the Indenture or certain defaults
hereunder and their consequences provided for in the Indenture, or (iii) modify
any of the provisions of Section 513, Section 902 or Section 1008 of the
Indenture, except to increase any such percentage or to provide that certain
other provisions of the Indenture cannot be modified or waived without the
consent of the Holder of each Outstanding Security affected thereby, provided
that, so long as any of the Capital Securities remains outstanding, no such
amendment shall be made that adversely affects the holders of the Capital
Securities, and no termination of the Indenture shall occur, and no waiver of an
Event of Default or compliance with any covenant under the Indenture shall be
effective, without the prior consent of the holders of at least a majority of
the aggregate liquidation amount of the outstanding Capital Securities unless
and until the principal of and any premium on the Securities and all accrued and
unpaid interest thereon have been paid in full.

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

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the office or agency of the Company in New York, New York, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the 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, will be issued to the designated transferee or transferees. No
service charge shall be made for any such registration of transfer or exchange,

                  (c) If and to the extent that any provision of this
Declaration conflicts with the duties imposed by Sections 310 to 317, inclusive,
of the Trust Indenture Act, such imposed duties shall control.

                  (d) The application of the Trust Indenture Act to this

United States Federal income tax purposes and shall not affect the nature of the
Securities as equity securities representing undivided beneficial ownership
interests in the assets of the Trust.

                  Section 2.2  Lists of Holders of Securities.

                  (a) Each of the Sponsor and the Regular Trustees on behalf of

December 31 of each year and current as of such date, and (ii) at any other
time, within 30 days of receipt by the Trust of a written request from the

Sponsor nor the Regular Trustees on behalf of the Trust shall be obligated to
provide such List of Holders at any time the List of Holders does not differ

Sponsor and the Regular Trustees on behalf of the Trust. The Property Trustee
shall preserve, in as current a form as is reasonably practicable, all
information contained in Lists of Holders given to it or which it receives in

Property Trustee may destroy any List of Holders previously given to it on
receipt of a new List of Holders.

                  (b) The Property Trustee shall comply with its obligations
under, and shall be entitled to the benefits of, Sections 311(a), 311(b) and

                  Section 2.6  Trust Enforcement Events; Waiver.

                  (a) The Holders of a Majority in Liquidation Amount of the
Capital Securities may, by vote or written consent, on behalf of the Holders of
all of the Capital Securities, waive any past Trust Enforcement Event in respect
of the Capital Securities and its consequences, provided that, if the underlying
Indenture Event of Default:

                           (i)      is not waivable under the Indenture, the
                                    Trust Enforcement Event under the
                                    Declaration shall also not be waivable; or

                           (ii)     requires the consent or vote of greater than
                                    a majority in principal amount of the
                                    holders of the Debentures (a "Super
                                    Majority") to be waived under the Indenture,
                                    the Trust Enforcement Event under the
                                    Declaration may only be waived by the vote
                                    or written consent of the Holders of at
                                    least the proportion in liquidation amount
                                    of the Capital Securities that the relevant
                                    Super Majority represents of the aggregate
                                    principal amount of the Debentures
                                    outstanding.

                  The foregoing provisions of this Section 2.6(a) 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. Upon
such waiver, any such default shall cease to exist, and any Trust Enforcement
Event with respect to the Capital Securities arising therefrom shall be deemed
to have been cured, for every purpose of this Declaration and the Capital
Securities, but no such waiver shall extend to any subsequent or other Trust
Enforcement Event with respect to the Capital Securities or impair any right
consequent thereon. Any waiver by the Holders of the Capital Securities of a
Trust Enforcement Event with respect to the Capital Securities shall also be
deemed to constitute a waiver by the Holders of the Common Securities of any
such Trust Enforcement Event 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.

                  (b) The Holders of a Majority in Liquidation Amount of the
Common Securities may, by vote or written consent, on behalf of the Holders of
all of the Common Securities, waive any past Trust Enforcement Event in respect
of the Common Securities and its consequences, provided that, if the underlying
Indenture Event of Default:

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

                           (ii)     requires the consent or vote of a Super
                                    Majority to be waived under the Indenture,
                                    except where the Holders of the Common
                                    Securities are deemed to have waived such
                                    Trust Enforcement Event under the
                                    Declaration as provided below in this
                                    Section 2.6(b), the Trust Enforcement Event
                                    under the Declaration may only be waived by
                                    the vote or written consent of the Holders
                                    of at least the proportion in 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 Trust Enforcement Event and all Trust Enforcement
Events with respect to the Common Securities and the consequences thereof until
all Trust Enforcement Events with respect to the Capital Securities have been
cured, waived or otherwise eliminated, and until such Trust Enforcement Events
with respect to the Capital Securities 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 Trust Enforcement Event 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 to any subsequent
or other Trust Enforcement Event with respect to the Common Securities or impair
any right consequent thereon.

                  (c) A waiver of an Indenture Event of Default by the Property
Trustee at the direction of the Holders of the Capital Securities constitutes a
waiver of the corresponding Trust Enforcement Event with respect to the Capital
Securities 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  Trust Enforcement Event; Notice.

                  (a) The Property Trustee shall, within 90 days after the
occurrence of a Trust Enforcement Event actually known to a Responsible Officer
of the Property Trustee, transmit

by mail, first class postage prepaid, to the Holders of the Securities, notices
of all such defaults with respect to the Securities, 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 Indenture Event of
Default, 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 of the Securities.

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

                           (i)      a default under Sections 501(1) and 501(2)
                                    of the Indenture; 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
                                    this Declaration shall have actual
                                    knowledge.

                                    of his rights or powers, if he shall have
                                    reasonable grounds for believing that the
                                    repayment of such funds or liability is not
                                    reasonably assured to him under the terms of

                           Regular Trustee to so act or as to his compliance
                           with any of the terms and provisions of this

                           or within the discretion or rights or powers
                           conferred upon it by this Declaration.

                  The Regular Trustees shall exercise the powers set forth in

                           whatsoever (except to the extent expressly authorized
                           in this Declaration or by the terms of the
                           Securities);

                           ownership of, or beneficial interest in, the Trust

                           upon the Debenture Trustee with respect to the
                           Debentures, (B) waive any past default that is

                           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, in each case, the Trust shall have received
                           (x) the prior approval of the Majority in Liquidation
                           Amount of the Capital Securities; provided, however,
                           that where a consent or action under the Indenture
                           would require the consent or act of the holders of
                           more than a majority of the aggregate liquidation
                           amount of Debentures affected thereby, only the

                           required under the Indenture may direct the Property
                           Trustee to give such consent to take such action and,

                           termination under clause (D) only, (y) an opinion of
                           counsel to the effect that such modification will not
                           cause more than an insubstantial risk that the Trust
                           will be deemed an Investment Company required to be
                           registered under the Investment Company Act, or the
                           Trust will not be classified as a grantor trust for
                           United States Federal income tax purposes; or

                  (ix)     take any action inconsistent with the status of the
                           Trust as a grantor trust for United States federal
                           income tax purposes; or

                  (x)      revoke any action previously authorized or approved
                           by a vote of the Holders of the Capital Securities
                           except pursuant to a subsequent vote of the Holders
                           of the Capital Securities.

                  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 Trust and the Holders of the Securities. 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
6.6. 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 Regular 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 Account") in the name of and under
                                    the exclusive control of the Property
                                    Trustee on behalf of the Holders of the
                                    Securities 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 Account and make
                                    payments to the Holders of the Capital
                                    Securities and Holders of the Common
                                    Securities from the Property Account in
                                    accordance with Section 7.2. Funds in the
                                    Property Account shall be held uninvested
                                    until disbursed in accordance with this
                                    Declaration. The Property 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

                                    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 Capital Securities and
                                    the Common Securities to the extent the
                                    Debentures are redeemed or mature; and

                       (iii)        upon written notice of distribution issued
                                    by the Regular Trustees in accordance with
                                    the terms of the Securities, engage in such
                                    ministerial activities as so directed and as
                                    shall be necessary or appropriate to effect
                                    the distribution of the Debentures to
                                    Holders of Securities upon the occurrence of
                                    a Special Event.

                  (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 this Declaration and the Securities.

                  (e) The Property Trustee shall take any Legal Action which
arises out of or in connection with a Trust Enforcement Event 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; provided, however, that if a Trust Enforcement Event has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay interest or principal (or premium, if any) on the Debentures on the date
such interest or principal (or premium, if any) 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
Security 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; provided,
however, that no Holder of the Common Securities may exercise any such right of
subrogation so long as a Trust Enforcement Event with respect to the Capital
Securities has occurred and is continuing.

                  (f)      The Property Trustee shall continue to serve as a
                           Trustee until either:

                           (i)      the Trust has been completely liquidated and
                                    the proceeds of the liquidation distributed
                                    to the Holders of Securities 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 6.6.

                  (g) Subject to such limitations as are necessary to insure
compliance with Section 3.3, 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 a
Trust Enforcement Event actually known to a Responsible Officer of the Property
Trustee occurs and is continuing, the Property Trustee shall, for the benefit of
Holders of the Securities, 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 may authorize one or more Persons
(each, a "Paying Agent") 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 Paying Agent may be removed by the Property Trustee at any time and a
successor Paying Agent or additional Paying Agents may be appointed at any time
by the Property Trustee. In the event that any of the Capital Securities are not
in the form of Global Securities, the Property Trustee will act as Paying Agent
and may designate an additional or substitute Paying Agent at any time.

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

                  The Property Trustee shall 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 subject to the limitations and
restrictions of applicable law, and the Property Trustee shall have no power to,
and 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 Trust
Enforcement Event and after the curing of all Trust Enforcement Events that may
have occurred, shall undertake to perform only such duties as are specifically
set forth in this Declaration and no implied covenants shall be read into this
Declaration against the Property Trustee. In case a Trust Enforcement Event 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 a Trust
                                    Enforcement Event and after the curing or
                                    waiving of all such Trust Enforcement Events
                                    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 the Property Trustee shall not be liable

                                    Trustee; and

                                    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

                                    case of any such certificates or opinions
                                    that by any provision hereof are

                           Trustee.

            (d) The Holders of the Common Securities shall use their best

of a Regular Trustee in accordance with Section 6.6, the

or more issuances, a class of capital securities representing undivided
beneficial ownership interests in the assets of the Trust (the "Transfer
Restricted Securities"), a class of capital securities to be only issued in
exchange for the Transfer Restricted Securities (the "New Capital Securities,"
and together with the Transfer Restricted Securities the "Capital Securities"),
and one class of common securities representing undivided beneficial ownership
interests in the assets of the Trust (the "Common Securities"). The aggregate
liquidation amount of Capital Securities and Common Securities that may be

                        Restricted Certificates evidencing the Capital
                        Securities shall be substantially in the form of Exhibit
                        A 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; provided, that the New Capital
                        Security Certificate shall not contain any of the
                        provisions following the Trustee's authentication.

               (ii)     Common Securities. The Common Securities of the Trust
                        will have a liquidation amount with respect to the
                        assets of the Trust of $1,000 per Common Security. The
                        Common Security Certificates evidencing the Common
                        Securities shall be substantially in the form of Exhibit
                        B to the Declaration, with such changes and additions
                        thereto or deletions therefrom as may be required by
                        ordinary usage, custom or practice.

            The Trust shall issue no securities or other interests in the assets
of the Trust other than the Capital Securities and the Common Securities.

            (b) Payment of Distributions on, and payments of the Redemption
Price upon a redemption of, the Capital Securities and the Common Securities, as
applicable, shall be made Pro Rata based on the liquidation amount of such
Capital Securities and Common Securities; provided, however, that if on any date
on which amounts payable on Distribution or redemption an Indenture Event of
Default shall have occurred and be continuing, no payment of any Distribution
on, or Redemption Price of, any of the Common Securities, and no other payment
on account of the redemption, liquidation or other acquisition of such Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions on all of the outstanding Capital Securities for all
Distribution periods terminating on or prior thereto, or in the case of amounts
payable on redemption the full amount of the Redemption Price for all of the
outstanding Capital Securities then called for redemption, shall have been made
or provided for, and all funds available to the Property Trustee shall first be
applied to the payment in full in cash of all Distributions on, or payments of
the Redemption Price upon a redemption of, the Capital Securities then due and
payable.

            (c) The Certificates shall be signed on behalf of the Trust by a
Regular Trustee. Such signature shall be the manual or facsimile signature of
any Regular Trustee. In case a Regular Trustee of the Trust who shall have
signed any of the Certificates shall cease to be such Regular Trustee before the
Certificates so signed shall be delivered by the
<PAGE>   45
                                                                              39


Trust, such Certificates nevertheless may be delivered as though the person who
signed such Certificates had not ceased to be such Regular Trustee; and any
Certificate may be signed on behalf of the Trust by such persons who, at the
actual date of execution of such Certificate, shall be the Regular Trustees of
the Trust, although at the date of the execution and delivery of the Declaration
any such person was not such a Regular Trustee. Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters, numbers or other marks of identification or designation
and such legends or endorsements as the Regular Trustees may deem appropriate,
or as may be required to comply with any law or with any rule or regulation of
any stock exchange on which Securities may be listed, or to conform to usage.

            A Certificate shall not be valid until authenticated by the manual
signature of an authorized officer of the Property Trustee. Such signature shall
be conclusive evidence that the Certificate has been authenticated under this
Declaration.

            In the event that the Trust elects to issue additional Securities
hereunder on a subsequent Closing Date, the Trust shall deliver to the Property
Trustee, in the manner provided in the following paragraph, duly executed
Certificates and a written order, together with such certificates and opinions
of counsel (in each case in substantially the form delivered at the initial
Closing Date), as are required for the issuance of Securities under this
Declaration, including the opinion of counsel required by Section 7.1(a).

            Upon a written order of the Trust signed by one Regular Trustee, the
Property Trustee shall authenticate the Certificates for original issue. The
aggregate number of Capital Securities outstanding at any time shall not exceed
the liquidation amount set forth in Section 7(a).

            The Property Trustee may appoint an authenticating agent acceptable
to the Trust to authenticate Certificates. An authenticating agent may
authenticate Certificates 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 of the Sponsor.

            (d) 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.

            (e) 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.

            (f) Every Person, by virtue of having become a Holder 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 and the
terms of the Securities, the Guarantee, the Indenture and the Debentures.

                                                                              40


            (g) The Securities shall have no preemptive rights.

            Section 7.2  Distributions.

            (a) Holders of Securities shall be entitled to receive cumulative
cash Distributions at a variable per annum rate on the stated liquidation amount
of $1,000 per Security equal to the variable per annum rate on the Debentures
calculated on the basis of the actual number of days elapsed in a year
consisting of twelve 30-day months. For any period shorter than a full 90-day
quarterly period, Distributions will be computed on the basis of the actual
number of days elapsed in such 90-day quarterly period. Subject to Section
7.1(b), Distributions shall be made on the Capital Securities and the Common
Securities on a Pro Rata basis. Distributions on the Securities shall be payable
quarterly only to the extent that the Trust has funds available for the payment
of such Distributions in the Property Account. Distributions not paid on the
scheduled payment date will accumulate and compound quarterly at the rate
payable on the Debentures, to the extent permitted by applicable law
("Compounded Distributions"). "Distributions" shall mean ordinary cumulative
distributions together with any Compounded Distributions. If and to the extent
that the Debenture Issuer makes a payment of interest (including Additional
Interest (as defined in the Indenture)), premium and/or principal on 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 Pro Rata distribution of the
Payment Amount to Holders, subject to the terms of Section 7.1(b).

            (b) Distributions on the Securities will be cumulative, will accrue
from June 8, 1997 and will be payable quarterly in arrears on the 15th day of
June, September, December and March, commencing September 15, 1997, when, as and
if available for payment, by the Property Trustee, except as otherwise described
below. If Distributions are not paid when scheduled, the accrued Distributions
shall be paid to the Holders of record of Securities as they appear on the books
and records of the Trust on the record date as determined under Section 7.2(c).

            (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 relevant
record dates, which relevant record date shall be the 1st day of the month in
which the relevant payment dates occur. In the event that any date on which
distributions are payable on the Securities is not a Business Day, payment of
the distribution payable on such date will be made on the next succeeding day
which is a Business Day (without any interest or other payment in respect of any
such delay) with the same force and effect as if made on such date.

            Section 7.3  Redemption of Securities; Distribution of Debentures.

            (a) Upon the repayment or redemption, in whole or in part, of the
Debentures, the proceeds from such repayment or redemption shall be
simultaneously applied Pro Rata (subject to Section 7.1(b)) to redeem Securities
having an aggregate liquidation amount equal to the aggregate principal amount
of the Debentures so repaid or redeemed for an amount equal to the redemption
price paid by the Debenture Issuer in respect of such Debentures plus
<PAGE>   47
                                                                              41


an amount equal to accrued and unpaid Distributions thereon through the date of
the redemption or such lesser amount as shall be received by the Trust in
respect of the Debentures so repaid or redeemed (the "Redemption Price").
Holders will be given not less than 30 or more than 60 days notice of such
redemption.

            (b) If, at any time, a Special Event shall occur and be continuing,
the Sponsor may elect to, unless the Debentures are redeemed, within 90 days
following the occurrence of such Special Event, cause the dissolution of the
Trust upon not less than 30 nor more than 60 days' notice and, after
satisfaction of the claims of creditors, if any, cause the Debentures to be
distributed to the Holders of the Common Securities and the Capital Securities
in liquidation of the Trust.

            (c) On the date fixed for any distribution of Debentures, upon
dissolution of the Trust, (i) the Capital Securities and the Common Securities
will no longer be deemed to be outstanding and (ii) certificates representing
Securities will be deemed to represent the Debentures having an aggregate
principal amount equal to the stated liquidation amount of, and bearing accrued
and unpaid interest equal to accrued and unpaid distributions on, such
Securities until such certificates are presented to the Sponsor or its agent for
transfer or reissuance.

            Section 7.4  Redemption Procedures.

            (a) 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 of Securities 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 on which notices are given
pursuant to this Section 7.4, 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 of Securities. 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.

            (b) If fewer than all the outstanding Securities are to be so
redeemed, the Common Securities and the Capital Securities will be redeemed Pro
Rata and the Capital Securities to be redeemed will be redeemed as described
below. The Trust may not redeem the Securities in part unless all accrued and
unpaid Distributions have been paid in full on all Securities then outstanding
plus accrued but unpaid Distributions to the date of redemption. For all
purposes of this Declaration, unless the context otherwise requires, all
provisions relating to the redemption of Capital Securities shall relate, in the
case of any Capital Security redeemed or to be redeemed only in part, to the
portion of the aggregate liquidation amount of Capital Securities which has been
or is to be redeemed.
<PAGE>   48
                                                                              42


            (c) If Securities are to be redeemed and the Trust gives a
Redemption/Distribution Notice, which notice may only be issued if the
Debentures are redeemed as set out in this Section 7.4 (which notice will be
irrevocable), then (A) by 12:00 noon, New York City time, on the redemption
date, the Property Trustee, upon receipt of such funds, will deposit irrevocably
with the DTC (in the case of Global Securities) or its nominee (or successor
clearing agency or its nominee) funds sufficient to pay the applicable
Redemption Price with respect to the Capital Securities and will give the DTC
irrevocable instructions and authority to pay the Redemption Price to the
Holders of the Capital Securities, and (B) with respect to Capital Securities
and Common Securities issued in definitive certificated form, the Property
Trustee will pay the relevant Redemption Price to the Holders of such Securities
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, then immediately prior to
the close of business on the date of such deposit, Distributions will cease to
accrue on the Securities so called for redemption and all rights of Holders of
such Securities will cease, except the right of the Holders of such Securities
to receive the Redemption Price, but without interest on such Redemption Price.
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) except that, if such Business Day falls in the
next calendar year, such payment will be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on such
date 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 Guarantee, Distributions
on such Securities will continue to accrue at the then applicable rate 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. For these purposes, the applicable Redemption
Price shall not include Distributions which are being paid to Holders who were
Holders on a relevant record date. Upon satisfaction of the foregoing
conditions, then immediately prior to the close of business on the date of such
deposit or payment, all rights of Holders of such Debentures so called for
redemption will cease, except the right of the Holders to receive the Redemption
Price, but without interest on such Redemption Price, and from and after the
date fixed for redemption, such Debentures will not accrue distributions or bear
interest.

            Neither the Regular Trustees nor the Trust shall be required to
register or cause to be registered the transfer or exchange of any Securities
that have been called for redemption, except in the case of any Securities being
redeemed in part, any portion thereof not to be redeemed.

            (d) Subject to the foregoing and applicable law (including, without
limitation, United States Federal securities laws), the Debenture Issuer 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.
<PAGE>   49
                                                                              43


            Section 7.5  Voting Rights of Capital Securities.

            (a) Except as provided under this Article VII and as otherwise
required by the Business Trust Act, the Trust Indenture Act and other applicable
law, the Holders of the Capital Securities will have no voting rights.

            (b) Subject to the requirement of the Property Trustee obtaining a
tax opinion in certain circumstances set forth in Section 7.5(d) below, the
Holders of 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 to the Property Trustee, or to direct the exercise of any trust
or power conferred upon the Property Trustee under the Declaration, including
the right to direct the Property Trustee, as Holder of the Debentures, to (i)
exercise the remedies available to it under the Indenture as a Holder of the
Debentures or (ii) consent to any amendment or modification of the Indenture or
the Debentures where such consent shall be required; provided, however, that
where a consent or action under the Indenture would require the consent or act
of the Holders of more than a majority in aggregate principal amount of
Debentures affected thereby, only the Holders of the percentage of the aggregate
stated liquidation amount of the Capital Securities which is at least equal to
the percentage required under the Indenture may direct the Property Trustee to
give such consent or to take such action.

            (c) If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of record of Capital Securities has made a written
request, such Holder of record of Capital Securities may, to the extent
permitted by applicable law, institute a legal proceeding directly against the
Debenture Issuer to enforce the Property Trustee's rights under the Indenture
without first instituting any legal proceeding against the Property Trustee or
any other person or entity. Notwithstanding the foregoing, if a Trust
Enforcement Event has occurred and is continuing and such event is attributable
to the failure of the Debenture Issuer to make any required payment when due
under the Indenture, then a Holder of Capital Securities may directly institute
a proceeding against the Debenture Issuer for enforcement of such payment under
the Indenture.

            (d) The Property Trustee shall notify all Holders of the Capital
Securities of any notice of any Indenture Event of Default received from the
Debenture Issuer with respect to the Debentures. Such notice shall state that
such Indenture Event of Default also constitutes a Trust Enforcement Event.
Except with respect to directing the time, method, and place of conducting a
proceeding for a remedy, the Property Trustee shall be under no obligation to
take any of the actions described in clause 7.5(b)(i) and (ii) above unless the
Property Trustee has obtained an opinion of independent tax counsel to the
effect that as a result of such action, the Trust will not fail to be classified
as a grantor trust for United States Federal income tax purposes and each Holder
will be treated as owning an undivided beneficial ownership interest in the
Debentures.

            (e) In the event the consent of the Property Trustee, as the Holder
of the Debentures, is required under the Indenture with respect to any amendment
or modification of the Indenture, the Property Trustee shall request the
direction of the Holders of the Securities
<PAGE>   50
                                                                              44


with respect to such amendment or modification and shall vote with respect to
such amendment or modification as directed by a Majority in Liquidation Amount
of the Securities voting together as a single class; provided, however, that
where a consent under the Indenture would require the consent of the Holders of
more than a majority in aggregate principal amount of the Debentures, the
Property Trustee may only give such consent at the direction of the Holders of
at least the same proportion in aggregate stated liquidation amount of the
Securities. The Property Trustee shall not take any such action in accordance
with the directions of the Holders of the Securities unless the Property Trustee
has obtained an opinion of tax counsel to the effect that, as a result of such
action, the Trust will not be classified as other than a grantor trust for
United States Federal income tax purposes and each Holder will be treated as
owning an undivided beneficial ownership interest in the Debentures.

            (f) A waiver of an Indenture Event of Default with respect to the
Debentures will constitute a waiver of the corresponding Trust Enforcement
Event.

            (g) Any required 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 or
pursuant to written consent. The Regular 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 the following information: (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.

            (h) No vote or consent of the Holders of Capital Securities will be
required for the Trust to redeem and cancel Capital Securities or distribute
Debentures in accordance with the Declaration.

            (i) Notwithstanding that Holders of Capital Securities are entitled
to vote or consent under any of the circumstances described above, any of the
Securities that are owned at such time by the Debenture Issuer or any entity
directly or indirectly controlled by, or under direct or indirect common control
with, the Debenture Issuer, shall not be entitled to vote or consent and shall,
for purposes of such vote or consent, be treated as if such Securities were not
outstanding, provided, however that persons otherwise eligible to vote to whom
the Debenture Issuer or any of its subsidiaries have pledged Capital Securities
may vote or consent with respect to such pledged Capital Securities under any of
the circumstances described herein.

            (j) Holders of the Capital Securities will have no rights to appoint
or remove the Trustees, who may be appointed, removed or replaced solely by the
Debenture Issuer, as the Holder of all of the Common Securities.

            (a) Except as provided under Section 6.1(b) or this Section 7.6 or 
as otherwise required by the Business Trust Act, the Trust Indenture Act or 
other applicable law or provided by the Declaration, the Holders of the Common
Securities will have no voting rights.

            (b) The Holders of the Common Securities are entitled, in accordance
with Article 6 of the Declaration, to vote to appoint, remove or replace any
Trustee or to increase or decrease the number of Trustees.

            (c) Subject to Section 2.6 of the Declaration and only after all
Trust Enforcement Events with respect to the Capital Securities have been cured,
waived, or otherwise eliminated and subject to the requirement of the Property
Trustee obtaining a tax opinion in certain circumstances set forth in this
paragraph (c), the Holders of a Majority in liquidation amount of the Common
Securities have the right to direct the time, method and place of conduction any
proceeding for any remedy available to the Property Trustee, or direct the
exercise of any trust or power conferred upon the Property Trustee under the
Declaration, including the right to direct the Property Trustee, as Holder of
the Debentures, to (i) exercise the remedies available to it under the Indenture
as a Holder of the Debentures, or (ii) consent to any amendment or modification
of the Indenture or the Debentures where such consent shall be required;
provided, however, that where a consent or action under the Indenture would
require the consent or act of the Holders of more than a majority in aggregate
principal amount of Debentures affected thereby, only the Holders of the
percentage of the aggregate stated liquidation amount of the Common Securities
which is at least equal to the percentage required under the Indenture may
direct the Property Trustee to have such consent or take such action. Except
with respect to directing the time, method, and place of conducting a proceeding
for a remedy, the Property Trustee shall be under no obligation to take any of
the actions described in clause 7.6(c)(i) and (ii) above unless the Property
Trustee has obtained an opinion of independent tax counsel to the effect that,
as a result of such action, for United States Federal income tax purposes the
Trust will not fail to be classified as a grantor trust and each Holder will be
treated as owning an undivided beneficial ownership interest in the Debentures.

            (d) If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of record of Common Securities has made a written
request, such Holder of record of Common Securities may, to the extent permitted
by applicable law, directly institute a legal proceeding directly against the
Debenture Issuer, as sponsor of the Trust, to enforce the Property Trustee's
rights under the Debentures without first instituting any legal proceeding
against the Property Trustee or any other person or entity.

            (e) A waiver of an Indenture Event of Default with respect to the
Debentures will constitute a waiver of the corresponding Trust Enforcement
Event.

            (f) Any required 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 or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are
<PAGE>   52
                                                                              46


entitled to vote, or of any matter on which action by written consent of such
Holders is to be taken, to be mailed to each Holder of Common Securities. Each
such notice will include a statement setting forth the following information:
(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.

            (g) No vote or consent of the Holders of Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
Debentures in accordance with the Declaration and the terms of the Securities.

            Section 7.7  Paying Agent.

            In the event that any Capital Securities are not in book-entry only
form, the Trust shall maintain in the Borough of Manhattan, City of New York,
State of New York, an office or agency where the Capital Securities may be
presented for payment ("Paying Agent"). The Trust may appoint the paying agent
and may appoint one or more additional paying agents in such other locations as
it shall determine. The term "Paying Agent" includes any additional paying
agent. The Trust may change any Paying Agent without prior notice to the
Holders. The Trust shall notify the Property Trustee of the name and address of
any Paying Agent not a party to this Declaration. If the Trust fails to appoint
or maintain another entity as Paying Agent, the Property Trustee shall act as
such. The Trust or any of its Affiliates may act as Paying Agent. The New York
Affiliate of The First National Bank of Chicago shall initially act as Paying
Agent for the Capital Securities and the Common Securities. In the event 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 Debenture
Issuer) to act as Paying Agent. The Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Property Trustee and the
Debenture Issuer.

            Section 7.8  Transfer of Securities.

            (a) The Trust shall cause to be kept at the Corporate Trust Office
of the Property Trustee a register (the register maintained in such office being
herein sometimes referred to as the "Security Register") in which, subject to
such reasonable regulations as it may prescribe, the Trust shall provide for the
registration of Capital Securities and of transfers of Capital Securities. The
Property Trustee is hereby appointed "Security Registrar" for the purpose of
registering Capital Securities and transfers of Capital Securities as herein
provided.

            (b) Upon surrender for registration of transfer of any Security at
an office or agency of the Trust designated for such purpose, the Trust shall
execute, and the Property Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like aggregate principal amount.

            (c) At the option of the Holder, Securities may be exchanged for
other Securities 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
Trust shall execute, and the Property Trustee shall authenticate and deliver,
the Securities which the Holder making the exchange is entitled to receive.

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

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

            (f) If the Securities are to be redeemed in part, the Trust shall
not be required (A) to issue, register the transfer of or exchange any
Securities during a period beginning at the opening of business 15 days before
the day of the mailing of a notice of redemption of any such Securities selected
for redemption under Section 7.4 and ending at the close of business on the day
of such mailing, or (B) to 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.

            Section 7.9  Mutilated, Destroyed, Lost or Stolen Certificates.

            If:

            (a) any mutilated Certificates should be surrendered to the Regular
Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and

            (b) there shall be delivered to the Regular Trustees such security
or indemnity as may be required by them to keep each of them, the Sponsor and
the Trust harmless, then, in the absence of notice that such Certificate shall
have been acquired by a bona fide purchaser, any Regular Trustee on behalf of
the Trust shall execute and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination. In connection with the issuance of any new Certificate under this
Section 7.9, the Regular Trustees may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

            Section 7.10  Persons Deemed Security Holders.

            The Trustees may treat the Person in whose name any Certificate
shall be registered on the books and records of the Trust as the sole holder of
such Certificate and of the Securities represented by such Certificate for
purposes of receiving Distributions and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such Certificate or in the Securities represented by such
Certificate on the part of any other Person, whether or not the Trust shall have
actual or other notice thereof.

            Section 7.11  Global Securities.

            If the Trust shall establish that the Capital Securities are to be
issued in the form of one or more securities issued in book-entry form (each, a
"Global Security"), then a Regular Trustee on behalf of the Trust shall execute
and the Property Trustee shall authenticate and deliver one or more Global
Securities that (i) shall represent and shall be denominated in an amount equal
to the aggregate liquidation amount of all of the Capital Securities to be
issued in the form of Global Securities and not yet cancelled, (ii) shall be
registered in the name of the Depositary for such Global Security or Securities
or the nominee of such Depositary, and (iii) shall be delivered by the Property
Trustee to such Depositary or pursuant to such Depositary's instructions. Global
Securities shall bear a legend substantially to the following effect:

            "This Capital Security is a Global Security within the meaning of
the Declaration hereinafter referred to and is registered in the name of a
Depositary or a nominee of a Depositary. Notwithstanding the provisions of
Section 7.8 of the Declaration, unless and until it is exchanged in whole or in
part for Capital Securities in definitive registered form, a Global Security
representing all or a part of the Capital Securities may not be transferred in
the manner provided in Section 7.8 of the Declaration except as a whole by the
Depositary to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary or a nominee of such successor
Depositary. Every Capital Security delivered upon registration or transfer of,
or in exchange for, or in lieu of, this Global Security shall be a Global
Security subject to the foregoing, except in the limited circumstances described
above. Unless this certificate is presented by an authorized representative of
DTC to the Trust or its agent for registration of transfer, exchange or payment,
and any certificate issued is registered in the name of Cede & Co. or in such
other name as is requested by an authorized representative of DTC (and any
payment is to be made to Cede & Co. or to such other entity as is requested by
an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
registered owner hereof, Cede & Co., has an interest herein."

            Definitive Capital Securities issued in exchange for all or a part
of a Global Security pursuant to this Section 7.11 shall be registered in such
names and in such authorized denominations as the Depositary, pursuant to
instructions from its direct or indirect
<PAGE>   55
                                                                              49


participants or otherwise, shall instruct the Property Trustee. Upon execution
and authentication, the Property Trustee shall deliver such definitive Capital
Securities to the persons in whose names such definitive Capital Securities are
so registered.

            At such time as all interests in Global Securities have been
redeemed, repurchased or canceled, such Global Securities shall be, upon receipt
thereof, canceled by the Property Trustee in accordance with standing procedures
and instructions existing between the Depositary and the Property Trustee. At
any time prior to such cancellation, if any interest in Global Securities is
exchanged for definitive Capital Securities, redeemed, canceled or transferred
to a transferee who receives definitive Capital Securities therefor or any
definitive Capital Security is exchanged or transferred for part of Global
Securities, the principal amount of such Global Securities shall, in accordance
with the standing procedures and instructions existing between the Depositary
and the Property Trustee, be reduced or increased, as the case may be, and an
endorsement shall be made on such Global Securities by the Property Trustee or
the Property Trustee, at the direction of the Property Trustee, to reflect such
reduction or increase.

            The Trust and the Property Trustee may for all purposes, including
the making of payments due on the Capital Securities, deal with the Depositary
as the authorized representative of the Holders for the purposes of exercising
the rights of Holders hereunder. The rights of the owner of any beneficial
interest in a Global Security shall be limited to those established by law and
agreements between such owners and depository participants or Euroclear and
Cedel; provided that no such agreement shall give any rights to any person
against the Trust or the Property Trustee without the written consent of the
parties so affected. Multiple requests and directions from and votes of the
Depositary as holder of Capital Securities in global form with respect to any
particular matter shall not be deemed inconsistent to the extent they do not
represent an amount of Capital Securities in excess of those held in the name of
the Depositary or its nominee.

            If at any time the Depositary for any Capital Securities represented
by one or more Global Securities notifies the Trust that it is unwilling or
unable to continue as Depositary for such Capital Securities or if at any time
the Depositary for such Capital Securities shall no longer be eligible under
this Section 7.11, the Trust shall appoint a successor Depositary with respect
to such Capital Securities. If a successor Depositary for such Capital
Securities is not appointed by the Trust within 90 days after the Trust receives
such notice or becomes aware of such ineligibility, the Trust's election that
such Capital Securities be represented by one or more Global Securities shall no
longer be effective and a Regular Trustee on behalf of the Trust shall execute,
and the Property Trustee will authenticate and deliver, Capital Securities in
definitive registered form, in any authorized denominations, in an aggregate
liquidation amount equal to the principal amount of the Global Security or
Global Securities representing such Capital Securities in exchange for such
Global Security or Global Securities.

            The Trust may at any time and in its sole discretion determine that
the Capital Securities issued in the form of one or more Global Securities shall
no longer be represented by a Global Security or Global Securities. In such
event a Regular Trustee on behalf of the
<PAGE>   56
                                                                              50


Trust shall execute, and the Property Trustee shall authenticate and deliver,
Capital Securities in definitive registered form, in any authorized
denominations, in an aggregate liquidation amount equal to the principal amount
of the Global Security or Global Securities representing such Capital
Securities, in exchange for such Global Security or Global Securities.

            Notwithstanding any other provisions of this Declaration (other than
the provisions set forth in Section 7.13(a)), Global Securities may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

            Interests of beneficial owners in a Global Security may be
transferred or exchanged for definitive Capital Securities and definitive
Capital Securities may be transferred or exchange for Global Securities in
accordance with rules of the Depositary and the provisions of Section 7.13.

            Any Capital Security in global form may be endorsed with or have
incorporated in the text thereof such legends or recitals or changes not
inconsistent with the provisions of this Declaration as may be required by the
Property Trustee, the Depositary or by the National Association of Securities
Dealers, Inc. in order for the Capital Securities to be tradeable on the PORTAL
Market or as may be required for the Capital Securities to be tradeable on any
other market developed for trading of securities pursuant to Rule 144A or
required to comply with any applicable law or any regulation thereunder or with
Regulation S or with the rules and regulations of any securities exchange upon
which the Capital Securities may be listed or traded or to conform with any
usage with respect thereto, or to indicate any special limitations or
restrictions to which any particular Capital Securities are subject.

            Section 7.12  Restrictive Legend.

            (a) Each Global Security and definitive Capital Security that
constitutes a Restricted Security shall bear the following legend (the "Private
Placement Legend") on the face thereof until three years after the later of the
date of original issue and the last date on which the Sponsor or any affiliate
of the Sponsor was the owner of such Capital Securities (or any predecessor
thereto) (the "Resale Restriction Termination Date"), unless otherwise agreed by
the Trust and the Holder thereof:

            "THIS CAPITAL SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR

      THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION
      5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF

      ACCEPTANCE HEREOF, REPRESENTS, ACKNOWLEDGES AND AGREES FOR THE BENEFIT OF
      THE TRUST THAT: (I) IT HAS ACQUIRED A "RESTRICTED" SECURITY WHICH HAS NOT
      BEEN REGISTERED UNDER THE SECURITIES ACT; (II) IT WILL NOT OFFER, SELL OR
      OTHERWISE TRANSFER THIS CAPITAL SECURITY PRIOR TO THE LATER OF THE DATE
      WHICH IS TWO YEARS AFTER THE DATE OF ORIGINAL ISSUANCE HEREOF AND THE LAST
      DATE ON WHICH THE TRUST OR ANY AFFILIATE OF THE TRUST WAS THE OWNER OF
      SUCH RESTRICTED SECURITIES (OR ANY PREDECESSOR) EXCEPT (A) TO THE TRUST,

      UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THIS CAPITAL SECURITY IS
      ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON WHO THE SELLER
      REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
      RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE
      REQUIREMENTS OF RULE 144A, (D) OUTSIDE THE UNITED STATES IN A TRANSACTION
      MEETING THE REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT, OR (E)

      OF THE ISSUER OF THIS CAPITAL SECURITY AND THE PROPERTY TRUSTEE FOR SUCH
      CAPITAL SECURITIES TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL,
      CERTIFICATIONS OR OTHER INFORMATION ACCEPTABLE TO THEM IN FORM AND
      SUBSTANCE."

            Any Capital Security (or security issued in exchange or substitution
therefor) as to which such restrictions on transfer shall have expired in
accordance with their terms may, upon satisfaction of the requirements of
Section 7.12(b) and surrender of such Capital Security for exchange to the
Capital Security registrar in accordance with the provisions of this Section
7.12(a), be exchanged for a new Capital Security or Capital Securities, of like
tenor and aggregate liquidation amount, which shall not bear the restrictive
legend required by this Section 7.12(a).

            (b) Upon any sale or transfer of any Restricted Security (including
any interest in a Global Security) (i) that is effected pursuant to an effective
registration statement under the Securities Act or (ii) in connection with which
the Property Trustee receives certificates and other information (including an
opinion of counsel, if requested) reasonably acceptable to the Sponsor and the
Property Trustee to the effect that such security will no longer be subject to
the resale restrictions under federal and state securities laws, then (A) in the
case of a Restricted Security in definitive form, the Capital Security registrar
or co-registrar shall permit the holder thereof to exchange such Restricted
Security for a security

that does not bear the legend set forth in Section 7.12(a), and shall rescind
any such restrictions on transfer and (B) in the case of Restricted Securities
represented by a Global Security, such Capital Security shall no longer be
subject to the restrictions contained in the legend set forth in Section 7.12(a)
(but still subject to the other provisions hereof). In addition, any Capital
Security (or security issued in exchange or substitution therefor) as to which
the restrictions on transfer described in the legend set forth in Section
7.12(a) have expired by their terms, may, upon surrender thereof (in accordance
with the terms of this Declaration) together with such certifications and other
information (including an opinion of counsel having substantial experience in
practice under the Securities Act and otherwise reasonably acceptable to the
Sponsor, addressed to the Sponsor and the Property Trustee and in a form
acceptable to the Sponsor, to the effect that the transfer of such Restricted
Security has been made in compliance with Rule 144 or such successor provision)
acceptable to the Sponsor and the Property Trustee as either of them may
reasonably require, be exchanged for a new Capital Security or Capital
Securities of like tenor and aggregate liquidation amount, which shall not bear
the restrictive legends set forth in Section 7.12(a).

            Section 7.13  Special Transfer Provisions.

            (a) At any time at the request of the beneficial holder of a Capital
Security in global form, such beneficial holder shall be entitled to obtain a
definitive Capital Security upon written request to the Property Trustee in
accordance with the standing instructions and procedures existing between the
Depositary and the Property Trustee for the issuance thereof. Any transfer of a
beneficial interest in a Capital Security in global form which cannot be
effected through book-entry settlement must be effected by the delivery to the
transferee (or its nominee) of a definitive Capital Security or Securities
registered in the name of the transferee (or its nominee) on the books
maintained by the Capital Securities registrar. With respect to any such
transfer, the Property Trustee will cause, in accordance with the standing
instructions and procedures existing between the Depositary and the Property
Trustee, the aggregate liquidation amount of the Global Security to be reduced
and, following such reduction, the Property Trustee will cause definitive
Capital Securities in the appropriate aggregate liquidation amount registered in
the name of such transferee (or its nominee) and bearing such restrictive
legends as may be required by this Declaration to be delivered. In connection
with any such transfer, the Property Trustee may request such representations
and agreements relating to the restrictions on transfer of such Capital
Securities from such transferee (or such transferee's nominee) as the Property
Trustee may reasonably require.

            (b) So long as the Capital Securities are eligible for book-entry
settlement, or unless otherwise required by law, upon any transfer of a
definitive Capital Security to a QIB in accordance with Rule 144A, unless
otherwise requested by the transferor, and upon receipt of the definitive
Capital Security being so transferred, together with a certification from the
transferor that the transferor reasonably believes the transferee is a QIB (or
other evidence satisfactory to the Property Trustee), the Property Trustee shall
make an endorsement on the Restricted Global Security to reflect an increase in
the aggregate liquidation amount of the Restricted Global Security, and the
Property Trustee shall cancel such definitive Capital Security and cause, in
accordance with the standing instructions and procedures existing
<PAGE>   59
                                                                              53


between the Depositary and the Property Trustee, the aggregate liquidation
amount of Capital Securities represented by the Restricted Global Security to be
increased accordingly.

            (c) So long as the Capital Securities are eligible for book-entry
settlement, or unless otherwise required by law, upon any transfer of a
definitive Capital Security in accordance with Regulation S, if requested by the
transferor, and upon receipt of the definitive Capital Security or Capital
Securities being so transferred, together with a certification from the
transferor that the transfer was made in accordance with Rule 903 or 904 of
Regulation S or Rule 144 under the Securities Act (or other evidence
satisfactory to the Property Trustee), the Property Trustee shall make or direct
the custodian for the Global Securities to make, an endorsement on the
Regulation S Global Security to reflect an increase in the aggregate liquidation
amount of the Capital Securities represented by the Regulation S Global
Security, the Property Trustee shall cancel such definitive Capital Security or
Capital Securities and cause, or direct the custodian to cause, in accordance
with the standing instructions and procedures existing between the Depositary
and the Property Trustee, the aggregate liquidation amount of Capital Securities
represented by the Regulation S Global Security to be increased accordingly.

            (d) If a holder of a beneficial interest in the Restricted Global
Security wishes at any time to exchange its interest in the Restricted Global
Security for an interest in the Regulation S Global Security, or to transfer its
interest in the Restricted Global Security to a person who wishes to take
delivery thereof in the form of an interest in the Regulation S Global Security,
such holder may, subject to the rules and procedures of the Depositary and to
the requirements set forth in the following sentence, exchange or cause the
exchange or transfer or cause the transfer of such interest for an equivalent
beneficial interest in the Regulation S Global Security. Upon receipt by the
Property Trustee, as transfer agent of (1) instructions given in accordance with
the Depositary's procedures from or on behalf of a holder of a beneficial
interest in the Restricted Global Security, directing the Property Trustee (via
DWAC), as transfer agent, to credit or cause to be credited a beneficial
interest in the Regulation S Global Security in an amount equal to the
beneficial interest in the Restricted Global Security to be exchanged or
transferred, (2) a written order given in accordance with the Depositary's
procedures containing information regarding the Euroclear or Cedel account to be
credited with such increase and the name of such account, and (3) a certificate
given by the holder of such beneficial interest stating that the exchange or
transfer of such interest has been made pursuant to and in accordance with Rule
903 or Rule 904 of Regulation S or Rule 144 under the Securities Act (or other
evidence satisfactory to the Property Trustee), the Property Trustee, as
transfer agent, shall promptly deliver appropriate instructions (via DWAC) to
the Depositary, its nominee, or the custodian for the Depositary, as the case
may be, to reduce or reflect on its records a reduction of the Restricted Global
Security by the aggregate liquidation amount of the beneficial interest in such
Restricted Global Security to be so exchanged or transferred from the relevant
participant, and the Property Trustee, as transfer agent, shall promptly deliver
appropriate instructions (via DWAC) to the Depositary, its nominee, or the
custodian for the Depositary, as the case may be, concurrently with such
reduction, to increase or reflect on its records an increase of the liquidation
amount of such Regulation S Global Security by the aggregate liquidation amount
of the beneficial interest in such Restricted Global Security to be so exchanged
or transferred, and to credit or cause to be
<PAGE>   60
                                                                              54


credited to the account of the person specified in such instructions (who may be
Morgan Guaranty Trust Company of New York, Brussels office, as operator of
Euroclear, or Cedel or another agent member of Euroclear, or Cedel, or both, as
the case may be, acting for and on behalf of them) a beneficial interest in such
Regulation S Global Security equal to the reduction in the liquidation amount of
such Restricted Global Security.

            (e) If a holder of a beneficial interest in the Regulation S Global
Security wishes at any time to exchange its interest in the Regulation S Global
Security for an interest in the Restricted Global Security, or to transfer its
interest in the Regulation S Global Security to a person who wishes to take
delivery thereof in the form of an interest in the Restricted Global Security,
such holder may, subject to the rules and procedures of Euroclear or Cedel and
the Depositary, as the case may be, and to the requirements set forth in the
following sentence, exchange or cause the exchange or transfer or cause the
transfer of such interest for an equivalent beneficial interest in such
Restricted Global Security. Upon receipt by the Property Trustee, as transfer
agent of (l) instructions given in accordance with the procedures of Euroclear
or Cedel and the Depositary, as the case may be, from or on behalf of a
beneficial owner of an interest in the Regulation S Global Security directing
the Property Trustee, as transfer agent, to credit or cause to be credited a
beneficial interest in the Restricted Global Security in an amount equal to the
beneficial interest in the Regulation S Global Security to be exchanged or
transferred, (2) a written order given in accordance with the procedures of
Euroclear or Cedel and the Depositary, as the case may be, containing
information regarding the account with the Depositary to be credited with such
increase and the name of such account, and (3) prior to the expiration of the
related Restricted Period, a certificate given by the holder of such beneficial
interest and stating that the person transferring such interest in such
Regulation S Global Security reasonably believes that the person acquiring such
interest in the Restricted Global Security is a QIB and is obtaining such
beneficial interest in a transaction meeting the requirements of Rule 144A and
any applicable securities laws of any state of the United States or any other
jurisdiction (or other evidence satisfactory to the Property Trustee), the
Property Trustee, as transfer agent, shall promptly deliver (via DWAC)
appropriate instructions to the Depositary, its nominee, or the custodian for
the Depositary, as the case may be, to reduce or reflect on its records a
reduction of the Regulation S Global Security by the aggregate liquidation
amount of the beneficial interest in such Regulation S Global Security to be
exchanged or transferred, and the Property Trustee, as transfer agent, shall
promptly deliver (via DWAC) appropriate instructions to the Depositary, its
nominee, or the custodian for the Depositary, as the case may be, concurrently
with such reduction, to increase or reflect on its records an increase of the
liquidation amount of the Restricted Global Security by the aggregate
liquidation amount of the beneficial interest in the Regulation S Global
Security to be so exchanged or transferred, and to credit or cause to be
credited to the account of the person specified in such instructions a
beneficial interest in the Restricted Global Security equal to the reduction in
the liquidation amount of the Regulation S Global Security. After the expiration
of the related Restricted Period, the certification requirement set forth in
clause (3) of the second sentence of this Section 7.13(e) will no longer apply
to such exchanges and transfers.

            (f) Any beneficial interest in one of the Global Securities that is
transferred to a person who takes delivery in the form of an interest in the
other Global Security will, upon
<PAGE>   61
                                                                              55


transfer, cease to be an interest in such Global Security and become an interest
in the other Global Security and, accordingly, will thereafter be subject to all
transfer restrictions and other procedures applicable to beneficial interests in
such other Global Security for as long as it remains such an interest.

            (g) For each Closing Date, prior to or on the 40th day after the
later of the commencement of the offering of the Capital Securities issued in
connection with such Closing Date and such Closing Date (each such period, a
"Restricted Period"), beneficial interests in a Regulation S Global Security
issued in connection with such Closing Date may only be held through Morgan
Guaranty Trust Company of New York, Brussels office, as operator of Euroclear,
or Cedel or another agent member of Euroclear and Cedel acting for and on behalf
of them, unless delivery is made through a Restricted Global Security in
accordance with the certification requirements hereof. During a Restricted
Period, interests in the Regulation S Global Security may be exchanged for
interests in a Restricted Global Security or for definitive Capital Securities
only in accordance with the certification requirements described above.

                        occurrence and continuation of a Special Event, pursuant
                        to which the Trust shall have been dissolved in
                        accordance with the terms of the Securities, and all of
                        the Debentures shall have been distributed to the
                        Holders of Securities in exchange for all of the
                        Securities; or

               (vi)     an election by a Majority in Liquidation Amount of the
                        Common Securities provided such action is taken before
                        the issuance of any Securities.

            (b) As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a) and upon completion of the winding up of the Trust
in accordance with Section 8.2 hereof, the Trustees shall terminate the Trust by
filing a certificate of cancellation with the Secretary of State of the State of
Delaware.

            (c) The provisions of Section 3.9 and Article 10 shall survive the
termination of the Trust.

            Section 8.2 Liquidation Distribution Upon Termination and
Dissolution of the Trust.

            (a) In the event of any voluntary or involuntary liquidation,
dissolution, winding-up or termination of the Trust (each a "Liquidation"), the
Holders of the Capital Securities on the date of the Liquidation will be
entitled to receive, out of the assets of the Trust available for distribution
to Holders of Securities after satisfaction of the Trust's liabilities in
accordance with applicable law, distributions in cash or other immediately
available funds in an amount equal to the aggregate of the stated liquidation
amount of $1,000 per Security plus accrued and unpaid Distributions thereon to
the date of payment (such amount being the "Liquidation Distribution"), unless,
in connection with such Liquidation, Debentures in an aggregate principal amount
equal to the aggregate liquidation amount of, with a Distribution rate
identical to the interest rate of, and accrued and unpaid distributions equal to
accrued and unpaid Distributions on, such Securities shall be distributed on a
Pro Rata basis to the Holders of the Securities in exchange for such Securities.

            (b) If, upon any such Liquidation, the Liquidation Distribution can
be paid only in part because the Trust has insufficient assets available to pay
in full the aggregate Liquidation Distribution, then the amounts payable
directly by the Trust on the Securities shall be paid on a Pro Rata basis. The
Holders of the Common Securities will be entitled to receive distributions upon
any such Liquidation Pro Rata with the Holders of the Capital Securities except
that if an Indenture Event of Default has occurred and is continuing, the
Capital Securities shall have a preference over the Common Securities with
regard to such distributions.

            (a) Except as expressly set forth in this Declaration, the Guarantee
and the terms of the Securities, the Sponsor:

                (i)     shall not be 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)     shall not be required to pay to the Trust or to any
                        Holder of Securities any deficit upon dissolution of the
                        Trust or otherwise.

            (b) The Holder of the Common Securities 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 9.2  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 or any such loss, damage or
claim incurred by reason of such Indemnified Person's 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 who has been selected with reasonable care
by or 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 existence and amount of assets from
which Distributions to Holders of Securities might properly be paid.

            Section 9.3  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 an 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
<PAGE>   64
                                                                              58


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; 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

               (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 9.4  Indemnification.

            (a)(i) The Debenture Issuer shall indemnify, to the full extent
permitted by law, any Debenture Issuer 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 Debenture Issuer Indemnified Person against
expenses (including attorney fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted
<PAGE>   65
                                                                              59


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 Debenture Issuer 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 Debenture Issuer shall indemnify, to the full extent
permitted by law, any Debenture Issuer 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 Debenture Issuer Indemnified
Person against expenses (including attorneys' fees) 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 Debenture Issuer 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) Any indemnification under paragraphs (i) and (ii) of this
Section 9.4(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 Debenture Issuer 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 Regular
Trustees by a majority vote of a quorum consisting of such Regular 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 Regular
Trustees so directs, by independent legal counsel in a written opinion, or (3)
by the Holder of the Common Securities of the Trust.

              (iv) Expenses (including attorneys' fees) incurred by a Debenture
Issuer Indemnified Person in defending a civil, criminal, administrative or
investigative action, suit or proceeding referred to in paragraphs (i) and (ii)
of this Section 9.4(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 Debenture Issuer 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 9.4(a).
Notwithstanding the foregoing, no advance shall be made by the Debenture Issuer
if a determination is reasonably and promptly made (i) by the Regular Trustees
by a majority vote of a quorum of disinterested Regular Trustees, (ii) if such a
quorum is not obtainable, or, even if obtainable, if a quorum of disinterested
Regular Trustees so directs, by independent legal counsel in a written opinion
<PAGE>   66
                                                                              60


or (iii) by the Holder of the Common Securities of the Trust, that, based upon
the facts known to the Regular Trustees, counsel or the Holder of the Common
Securities at the time such determination is made, such Debenture Issuer
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 Debenture Issuer 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 Regular Trustees,
independent legal counsel or Holder of the Common Securities reasonably
determine that such person deliberately breached his duty to the Trust or the
Holders of the Common or Capital Securities.

                (v) The indemnification and advancement of expenses provided by,
or granted pursuant to, the other paragraphs of this Section 9.4(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 Holder of the
Common Securities of the Trust or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office. All
rights to indemnification under this Section 9.4(a) shall be deemed to be
provided by a contract between the Debenture Issuer and each Debenture Issuer
Indemnified Person who serves in such capacity at any time while this Section
9.4(a) is in effect. Any repeal or modification of this Section 9.4(a) shall not
affect any rights or obligations then existing.

               (vi) The Debenture Issuer or the Trust may purchase and maintain
insurance on behalf of any person who is or was a Debenture Issuer 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 9.4(a).

              (vii) For purposes of this Section 9.4(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 9.4(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.

             (viii) The indemnification and advancement of expenses provided by,
or granted pursuant to, this Section 9.4(a) shall, unless otherwise provided
when authorized or ratified, continue as to a person who has ceased to be a
Debenture Issuer Indemnified Person and shall inure to the benefit of the heirs,
executors and administrators of such a person. The obligation to indemnify as
set forth in this Section 9.4(a) shall survive the satisfaction and discharge of
this Declaration.

            (b) The Debenture Issuer agrees to indemnify the (i) Property
Trustee, (ii) the Delaware Trustee, (iii) an Affiliate of the Property Trustee
and the Delaware Trustee, and (iv) any officers, directors, shareholders,
members, partners, employees, representatives,
<PAGE>   67
                                                                              61


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 loss, liability or expense incurred without negligence or bad faith
on its part, arising out of or in connection with the acceptance or
administration of the trust 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 provisions of this
Section 9.4(a) shall survive the satisfaction and discharge of this Declaration
or the resignation or removal of the Property Trustee or the Delaware Trustee,
as the case may be.

            Section 9.5  Outside Businesses.

            Any Covered Person, the Sponsor, the Delaware Trustee and the
Property Trustee may engage in or possess an interest in other business ventures
of any nature or description, independently or with others, similar or
dissimilar to the activities of the Trust, and the Trust and the Holders of
Securities 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 activities 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 10.1  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 10.2  Certain Accounting Matters.

            (a) At all times during the existence of the Trust, the Regular
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. The
Trust shall use the accrual method of accounting for United States

                                                                              62


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
Regular Trustees.

            (b) The Regular Trustees shall cause to be prepared and delivered to
each of the Holders of Securities, 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 Regular Trustees shall cause to be duly prepared and
delivered to each of the Holders of Securities, an 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 Regular Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

            (d) The Regular 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 Regular Trustees on behalf of the Trust with any state or local taxing
authority.

            Section 10.3  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 respect of the Debentures held by the Property Trustee shall be made directly
to the Property Account and no other funds of the Trust shall be deposited in
the Property Account. The sole signatories for such accounts shall be designated
by the Regular Trustees; provided, however, that the Property Trustee shall
designate the signatories for the Property Account.

            Section 10.4  Withholding.

            The Trust and the Regular 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 Regular 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

                                                                              63


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.

            Section 11.1 Amendments.

            (a) Except as otherwise provided in this Declaration or by any
applicable terms of the Securities, this Declaration may only be amended by a
written instrument approved and executed by (i) the Regular Trustees (or, if
there are more than two Regular Trustees, a majority of the Regular Trustees),

duties, obligations or immunities of the Property Trustee; and (iii) by the
Delaware Trustee if the amendment affects the rights, powers, duties,
obligations or immunities of the Delaware Trustee.

            (b) No amendment shall be made, and any such purported amendment
shall be void and ineffective:

               (i)      unless, in the case of any proposed amendment, the
                        Property Trustee shall have first received an Officers'
                        Certificate from each of the Trust and the Sponsor that
                        such amendment is permitted by, and conforms to, the
                        terms of this Declaration (including the terms of the
                        Securities);

               (ii)     unless, in the case of any proposed amendment which
                        affects the rights, powers, duties, obligations or
                        immunities of the Property Trustee, the Property Trustee

form as is reasonably practicable, all information contained in Lists of Holders
given to it, provided that it may destroy any List of Holders previously given

                  (b) The Guarantee Trustee shall comply with its obligations

a Majority in Liquidation Amount of the Securities may, by vote or written
consent, on behalf of the Holders of all of the Securities, waive any past

class postage prepaid, to the Holders of the Securities, notices of all such
Guarantee Events of Default, unless such defaults have been cured before the
giving of such notice; provided, that the Guarantee Trustee shall be protected
in withholding such notice if and so long as a Responsible Officer of the
Guarantee Trustee in good faith determines that the withholding of such notice
is in the interests of the Holders of the Securities.

                  (b) The Guarantee Trustee shall not be deemed to have
knowledge of any Guarantee Event of Default unless the Guarantee Trustee shall
have received written notice thereof or a Responsible Officer of the Guarantee
Trustee charged with the administration of the Declaration shall have obtained
actual knowledge thereof.

                  SECTION 2.8 Conflicting Interests. The Declaration shall be

information as to the names and addresses of the Holders of the Securities in
accordance with Section 312 of the Trust Indenture Act, regardless of the source
from which such information was derived, shall not be deemed to be a violation
of any existing law, or any law hereafter enacted which does not specifically
refer to Section 312 of the Trust Indenture Act, nor shall the Guarantee Trustee
be held accountable by reason of mailing any material pursuant to a request made
under Section 312(b) of the Trust Indenture Act.

authorized to (a) recover judgment, in its own name and as trustee of an express
trust, against the Guarantor for the whole amount of any Guarantee Payments
remaining unpaid and (b) file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have its claims and those of the
Holders of the Securities allowed in any judicial proceedings relative to the
Guarantor, its creditors or its property.

                                GUARANTEE TRUSTEE

                  SECTION 3.1 Powers and Duties of Guarantee Trustee.

                  (a) This Guarantee shall be held by the Guarantee Trustee on
behalf of the Trust for the benefit of the Holders of the Securities, and the
Guarantee Trustee shall not transfer this Guarantee to any Person except a
Holder of Securities exercising his or her rights pursuant to Section 5.4(b) or
to a Successor Guarantee Trustee on acceptance by such Successor Guarantee
Trustee. The right, title and interest of the Guarantee Trustee in and to this
Guarantee shall automatically vest in any Successor Guarantee Trustee, and such
vesting

                                                                               7



and succession of title shall be effective whether or not conveyancing documents
have been executed and delivered pursuant to the appointment of such Successor
Guarantee Trustee.

                  (b) If a Guarantee Event of Default actually known to a
Responsible Officer of the Guarantee Trustee has occurred and is continuing, the
Guarantee Trustee shall enforce this Guarantee for the benefit of the Holders of
the Securities.

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

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

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

                                    (A) the duties and obligations of the
                           Guarantee Trustee shall be determined solely by the
                           express provisions of this Guarantee, and the
                           Guarantee Trustee shall not be liable except for the
                           performance of such duties and obligations as are
                           specifically set forth in this Guarantee, and no
                           implied covenants or obligations shall be read into
                           this Guarantee against the Guarantee Trustee; and

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

                                (ii) the Guarantee Trustee shall not be
                  liable for any error of judgment made in good faith by a
                  Responsible Officer of the Guarantee
<PAGE>   12

                  Trustee, unless it shall be proved that the Guarantee Trustee
                  was negligent in ascertaining the pertinent facts upon which
                  such judgment was made;

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

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

to the provisions of Section 3.1:

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

                                 (ii) Any direction or act of the Guarantor
                  contemplated by this Guarantee shall be sufficiently evidenced
                  by an Officers' Certificate;

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

                                 (iv) The Guarantee Trustee shall have no duty
                  to see to any recording, filing or registration or any

                  thereof);

                                                                               9



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

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

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

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

                                 (ix) Any action taken by the Guarantee Trustee
                  or its agents hereunder shall bind the Holders of the
                  Securities, and the signature of the Guarantee Trustee or its
                  agents alone shall be sufficient and effective to perform any
                  such action. No third party shall be required to inquire as to
                  the authority of the Guarantee Trustee to so act or as to its
                  compliance with any of the terms and provisions of this
                  Guarantee, both of which shall be conclusively evidenced by
                  the Guarantee Trustee's or its agent's taking such action; and

                                  (x) Whenever in the administration of this
                  Guarantee the Guarantee Trustee shall deem it desirable to
                  receive instructions with respect to enforcing any remedy or
                  right or taking any other action hereunder, the Guarantee

                  Trustee (i) may request instructions from the Holders of a
                  Majority in Liquidation Amount of the Securities, (ii) may
                  refrain from enforcing such remedy or right or taking such
                  other action until such instructions are received, and (iii)
                  shall be protected in conclusively relying on or acting in
                  accordance with such instructions.

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

                  SECTION 3.3 Not Responsible for Recitals or Issuance of
Guarantee. The recitals contained in this Guarantee shall be taken as the
statements of the Guarantor, and the Guarantee Trustee does not assume any
responsibility for their correctness. The Guarantee Trustee makes no
representations as to the validity or sufficiency of this Guarantee.

                  corporation or Person permitted by the Securities and Exchange
                  Commission to act as an institutional trustee under the Trust
                  Indenture Act, authorized under such laws to exercise

                  published.

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

days after delivery to the Guarantor of an instrument of removal or resignation,

                                    GUARANTEE

                  SECTION 5.1  Guarantee.

                  The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Trust), as and when due, regardless of any defense,
right of set-off or counterclaim that the Trust may have or assert. The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Trust to pay such amounts to the Holders.

                  SECTION 5.2 Waiver of Notice and Demand.

                  The Guarantor hereby waives notice of acceptance of this
Guarantee and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the Trust or
any other Person before proceeding against the Guarantor, protest, notice of
nonpayment, notice of dishonor, notice of redemption and all other notices and
demands. Notwithstanding anything to the contrary herein, the Guarantor retains
all of its rights under the Indenture to extend the interest payment period on
the Debentures and the Guarantor shall not be obligated hereunder to make any
Guarantee Payments during any Extension Period (as defined in the Indenture)
with respect to the Distributions (as defined in the Declaration) on the
Securities.

                  SECTION 5.3  Obligations Not Affected.

                  The obligations, covenants, agreements and duties of the
Guarantor under this Guarantee shall be absolute and unconditional and shall
remain in full force and effect until the entire liquidation amount of all
outstanding Securities shall have been paid and such obligation shall in no way
be affected or impaired by reason of the happening from time to time of any
event, including without limitation, the following, whether or not with notice
to, or the consent of, the Guarantor:

                  (a) The release or waiver, by operation of law or otherwise,
         of the performance or observance by the Trust of any express or implied
         agreement, covenant, term or condition relating to the Securities to be
         performed or observed by the Trust;

                  (b) The extension of time for the payment by the Trust of all
         or any portion of the Distributions, Redemption Price (as defined in
         the Indenture), Liquidation Distribution or any other sums payable
         under the terms of the Securities or the extension of time for the
         performance of any other obligation under, arising out of, or in
         connection with the 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);

                                                                              13



                  (c) Any failure, omission, delay or lack of diligence on the
         part of the Property Trustee or the Holders to enforce, assert or
         exercise any right, privilege, power or remedy conferred on the
         Property Trustee or the Holders pursuant to the terms of the
         Securities, or any action on the part of the Trust 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 Trust or any of the assets of the Trust;

                  (e) Any invalidity of, or defect or deficiency in, the
         Securities;

                  (f) The settlement or compromise of any obligation guaranteed
         hereby or hereby incurred; or

                  (g) 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 hereunder shall be absolute and unconditional under any and
         all circumstances.

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

                  No setoff, counterclaim, reduction or diminution of any
obligation, or any defense of any kind or nature that the Guarantor has or may
have against any Holder shall be available hereunder to the Guarantor against
such Holder to reduce the payments to it under this Guarantee.

                  SECTION 5.4 Rights of Holders.

                  (a) The Holders of a Majority in Liquidation Amount of the
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of this
Guarantee or exercising any trust or power conferred upon the Guarantee Trustee
under this Guarantee.

                  (b) If the Guarantee Trustee fails to enforce this Guarantee,
then any Holder of Securities may, subject to the subordination provisions of
Section 6.2, institute a legal proceeding directly against the Guarantor to
enforce the Guarantee Trustee's rights under this Guarantee without first
instituting a legal proceeding against the Trust, the Guarantee Trustee or any
other person or entity. Notwithstanding the foregoing, if the Guarantor has
failed to make a Guarantee Payment, a Holder of Securities may, subject to the
subordination provisions of Section 6.2, directly institute a proceeding against
the Guarantor for enforcement of the Guarantee for such payment to the Holder of
the Securities of the principal of or interest on the Debentures on or after the
respective due dates specified in the
<PAGE>   18
                                                                              14



Debentures, and the amount of the payment will be based on the Holder's pro rata
share of the amount due and owing on all of the Securities. The Guarantor hereby
waives any right or remedy to require that any action on this Guarantee be
brought first against the Trust or any other person or entity before proceeding
directly against the Guarantor.

                  SECTION 5.5 Guarantee of Payment.

                  This 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 of Securities against the Trust in respect of any amounts paid to
such Holders by the Guarantor under this 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 of any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Guarantee, if at the time of any such payment,
any amounts are due and unpaid under this 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
Guarantee Trustee for the benefit of the Holders.

                  SECTION 5.7 Independent Obligations.

                  The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Trust with respect to the Securities, and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee notwithstanding the
occurrence of any event referred to in subsections 5.3(a) through 5.3(g),
inclusive, hereof.

                  SECTION 6.1 Limitation of Transactions.

                  So long as any Securities remain outstanding, if there shall
have occurred a Guarantee Event of Default or a Trust Enforcement Event, then
the Guarantor shall not, and shall not permit any subsidiary of the Guarantor,
to (i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, the Guarantor's capital
stock or (ii) make any payment of principal, interest or premium, if any, on or
repay, repurchase or redeem any debt securities of the Guarantor that rank pari
passu with or junior to the Debentures or make any guarantee payments with
respect to any guarantee by the Guarantor of the debt securities of any
subsidiary of the Guarantor if such guarantee ranks pari passu with or junior to
the Debentures (other than (a) repurchases,

connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of any one or more employees, officers,

                  3. Registered Exchange Offer.

                           (a) Unless the Exchange Offer shall not be
         permissible under applicable law or Commission policy (after the
         procedures set forth in Section 6(a) below have been complied with),
         the Company and the Trust shall (i) cause to be filed with the
         Commission as soon as practicable after the Closing Date, but in no
         event later than 60 days after the Closing Date, a Registration
         Statement under the Securities Act relating to the New Securities and
         the Exchange Offer, (ii) use their respective best efforts to cause
         such Registration Statement to become effective at the earliest
         possible time, but in no event later than 120 days after the Closing
         Date, (iii) in connection with the foregoing, file (A) all
         pre-effective amendments to such Registration Statement as may be
         necessary in order to cause such Registration Statement to become
         effective, (B) if applicable, a post-effective amendment to such
         Registration Statement pursuant to Rule 430A under the Securities Act
         and (C) all necessary filings in connection with the registration and
         qualification of the New Securities under the Blue Sky laws of such
         jurisdictions as are necessary to permit Consummation of the Exchange
         Offer, and (iv) unless the Exchange Offer would not be permitted by
         applicable law or Commission policy, the Company will commence the
         Exchange Offer and use its best efforts to issue on or prior to 30
         business days after the date on which such Registration Statement was
         declared effective by the Commission, New Securities in exchange for
         all Securities tendered prior thereto in the Exchange Offer. The
         Exchange Offer shall be on the appropriate form permitting registration
         of the New Securities to be offered in exchange for the Transfer
         Restricted Securities and to permit resales of New Securities held by
         Broker-Dealers as contemplated by Section 3(c) below.

                           (b) The Company and the Trust shall cause the
         Exchange Offer Registration Statement to be effective continuously and
         shall keep the Exchange Offer open for a period of not less than the
         minimum period required under applicable federal and state securities
         laws to Consummate the Exchange Offer; provided, however, that in no
         event shall such period be less than 20 business days. The Company and
         the Trust shall cause the Exchange Offer to comply with all applicable
         federal and state securities laws. No securities other than the New
         Securities shall be included in the Exchange Offer Registration
         Statement. The Company and the Trust shall use its best efforts to
         cause the Exchange Offer to be Consummated on the earliest practicable
         date after the Exchange Offer Registration Statement has become
         effective, but in no event later than 30 business days thereafter.

                           (c) The Company and the Trust shall indicate in a
         "Plan of Distribution" section contained in the Prospectus contained in
         the Exchange Offer Registration Statement that any Broker-Dealer who
         holds Securities that are Transfer Restricted Securities and that were
         acquired for its own account as a result of market-making activities or
         other trading activities (other than Transfer Restricted Securities
         acquired directly from the Company and the Trust), may exchange such
         Securities pursuant to the Exchange Offer; however, such Broker-Dealer
         may be deemed to be an "underwriter" within the meaning of the
         Securities Act and must, therefore, deliver a prospectus meeting the
         requirements of the Securities Act in connection with any resales of
         the New Securities received by such Broker-Dealer in the Exchange
         Offer, which prospectus delivery requirement may be satisfied by the
         delivery by such Broker-Dealer of the Prospectus contained in the
         Exchange Offer Registration Statement. Such "Plan of Distribution"
         section shall also contain all other information with respect to such
         resales by Broker-Dealers that the Commission may require in order to
         permit such resales pursuant thereto, but such "Plan of Distribution"
         shall not name any such Broker-Dealer or disclose the amount of New
         Securities
<PAGE>   7
                                                                               5

         held by any such Broker-Dealer except to the extent required by the
         Commission as a result of a change in policy announced after the date
         of this Agreement.

                  The Company and the Trust shall use their respective best
efforts to keep the Exchange Offer Registration Statement continuously
effective, supplemented and amended as required by the provisions of Section
6(c) below to the extent necessary to ensure that it is available for resales of
New Securities acquired by Broker-Dealers for their own accounts as a result of
market-making activities or other trading activities, and to ensure that it
conforms with the requirements of this Agreement, the Securities Act and the
policies, rules and regulations of the Commission as announced from time to
time, for a period of 180 days from the date on which the Exchange Offer
Registration Statement is declared effective.

                  The Company and the Trust shall provide sufficient copies of
the latest version of such Prospectus to Broker-Dealers promptly upon request at
any time during such 180-day period in order to facilitate such resales.

                  4. Shelf Registration.

                           (a) Shelf Registration. If (i) the Company and the
         Trust are not required to file an Exchange Offer Registration Statement
         or to consummate the Exchange Offer because the Exchange Offer is not
         permitted by applicable law or Commission policy (after the procedures
         set forth in Section 6(a) below have been complied with), (ii) the
         Company has received an opinion of counsel, rendered by a law firm
         having a nationally recognized tax practice, to the effect that, as a
         result of the Consummation of the Exchange Offer there is more than an
         insubstantial risk that (x) the Trust would be subject to United States
         federal income tax with respect to income received or accrued on the
         Junior Subordinated Debentures or New Junior Subordinated Debentures,
         (y) interest payable by the Company on such Junior Subordinated
         Debentures or New Junior Subordinated Debentures would not be
         deductible by the Company, in whole or in part, for United States
         federal income tax purposes, or (z) the Trust would be subject to more
         than a de minimis amount of other taxes, duties or other governmental
         charges or (iii) if any Holder of Transfer Restricted Securities that
         is a "qualified institutional buyer" (as defined in Rule 144A under the
         Securities Act) or an "accredited investor" (as defined in Rule
         501(a)(1), (2), (3) or (7) under the Securities Act) shall notify the
         Company at least 20 business days prior to the Consummation of the
         Exchange Offer (A) that such Holder is prohibited by applicable law or
         Commission policy from participating in the Exchange Offer, or (B) that
         such Holder may not resell the New Securities acquired by it in the
         Exchange Offer to the public without delivering a prospectus and that
         the Prospectus contained in the Exchange Offer Registration Statement
         is not appropriate or available for such resales by such Holder, or (C)
         that such Holder is a Broker-Dealer and holds Securities acquired
         directly from the Trust and the Company or one of its affiliates, then
         the Trust and the Company shall use their respective best efforts to:

                                    (x) cause to be filed a shelf registration
                  statement pursuant to Rule 415 under the Securities Act, which
                  may be an amendment to the Exchange Offer Registration
                  Statement (in either event, the "Shelf Registration
                  Statement"), on or prior to the earliest to occur of (1) the
                  30th day after the date on which the Trust and the Company
                  determines that they are not required to file the Exchange
                  Offer Registration Statement or (2) the 30th day after the
                  date on which the Trust and the Company receive notice from a
                  Holder of Transfer 
<PAGE>   8
                                                                             6

                  Restricted Securities as contemplated by clause (iii) above
                  (such earliest date being the "Shelf Filing Deadline"), which
                  Shelf Registration Statement shall provide for resales of all
                  Transfer Restricted Securities the Holders of which shall have
                  provided the information required pursuant to Section 4(b)
                  hereof; and

                                    (y) cause such Shelf Registration Statement
                  to be declared effective by the Commission on or before the
                  60th day after the Shelf Filing Deadline.

         The Trust and the Company shall use their respective best efforts to
         keep such Shelf Registration Statement continuously effective,
         supplemented and amended as required by the provisions of Sections 6(b)
         and (c) hereof to the extent necessary to ensure that it is available
         for resales of Securities by the Holders of Transfer Restricted
         Securities entitled to the benefit of this Section 4(a), and to ensure
         that it conforms with the requirements of this Agreement, the
         Securities Act and the policies, rules and regulations of the
         Commission as announced from time to time, for a period ending on the
         third anniversary of the Closing Date.

                           (b) Provision by Holders of Certain Information in
         Connection with the Shelf Registration Statement. No Holder of Transfer
         Restricted Securities may include any of its Transfer Restricted
         Securities in any Shelf Registration Statement pursuant to this
         Agreement unless and until such Holder furnishes to the Trust and the
         Company in writing, within 20 business days after receipt of a request
         therefor, such information as the Trust and the Company may reasonably
         request for use in connection with any Shelf Registration Statement or
         Prospectus or preliminary Prospectus included therein. No Holder of
         Transfer Restricted Securities shall be entitled to Additional
         Distributions pursuant to Section 5 hereof or Article 3 of the
         Indenture unless and until such Holder shall have used its best efforts
         to provide all such reasonably requested information. Each Holder as to
         which any Shelf Registration Statement is being effected agrees to
         furnish promptly to the Trust and the Company all information required
         to be disclosed in order to make the information previously furnished
         to the Trust and the Company by such Holder not materially misleading.

                  5. Additional Interest and Additional Distributions Under
Certain Circumstances.

                  (a) If (a) any of the Registration Statements required by this
Agreement is not filed with the Commission on or prior to the date specified for
such filing in this Agreement, (b) any of such Registration Statements has not
been declared effective by the Commission on or prior to the date specified for
such effectiveness in this Agreement (the "Effectiveness Target Date"), (c) the
Exchange Offer has not been Consummated within 30 business days after the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (d) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose (other than for any reason set forth in Section
6(c)(iii)(D) which shall not exceed 30 consecutive days, or 90 days in any
twelve month period) without being succeeded within two business days by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself immediately declared effective (each such event referred to
in clauses (a) through (d), a "Registration Default"), additional interest (the
"Additional Interest") shall become payable in respect of the Junior
Subordinated Debentures (including in respect of amounts accruing during any
Extension Period (as defined in the Indenture)) and corresponding additional
Distributions (the "Additional Distributions") shall become payable to each
Holder of Capital Securities (in its capacity as such and not in its capacity as
an indirect
<PAGE>   9
                                                                               7

holder of a pro rata share of the Junior Subordinated Debentures) with respect
to the first 90-day period immediately following the occurrence of such
Registration Default in an amount equal to $.25 per week per $1,000 liquidation
amount of Capital Securities held by such Holder for each week or portion
thereof that the Registration Default continues. The amount of Additional
Interest, and the corresponding amount of Additional Distributions payable to
any Holder of Capital Securities, shall increase by an additional $.05 per week
per $1,000 in liquidation amount of Capital Securities held by such Holder with
respect to each subsequent 90-day period until all Registration Defaults have
been cured, up to a maximum amount of Additional Interest (and corresponding
Additional Distributions) of $.50 per week per $1,000 liquidation amount of
Capital Securities. All accrued Additional Interest (and corresponding
Additional Distributions) shall be paid to Holders by the Trust and the Company
by wire transfer of immediately available funds or by federal funds check on the
last day of each such 90-day period. Following the cure of all Registration
Defaults relating to any particular Transfer Restricted Securities, the accrual
of Additional Interest (and corresponding Additional Distributions) with respect
to such Transfer Restricted Securities will cease.

                  All obligations of the Trust and the Company set forth in the
preceding paragraph that are outstanding with respect to any Transfer Restricted
Security at the time such security ceases to be a Transfer Restricted Security
shall survive until such time as all such obligations with respect to such
Transfer Restricted Security shall have been satisfied in full.

                  (b) The Trust and the Company shall notify the Property
Trustee within one business day after each and every date on which an event
occurs in respect of which Additional Distributions are required to be paid (an
"Event Date"). Additional Distributions shall be paid by depositing Additional
Interest with the Property Trustee, in trust, for the benefit of the Holders
thereof, on or before the applicable Interest Payment Date (whether or not any
payment other than Additional Distributions is payable on the Capital
Securities), immediately available funds in sums sufficient to pay the
Additional Distributions then due to Holders of Transfer Restricted Securities
with respect to which the Property Trustee serves. Each obligation to pay
Additional Interest and Additional Distributions shall be deemed to accrue from
the applicable date of the occurrence of the Registration Default.

                  6. Registration Procedures.

                           (a) Exchange Offer Registration Statement. In
         connection with the Exchange Offer, the Trust and the Company shall
         comply with all of the provisions of Section 6(c) below, shall use
         their best efforts to effect such exchange to permit the sale of
         Transfer Restricted Securities being sold in accordance with the
         intended method or methods of distribution thereof, and shall comply
         with all of the following provisions:

                                    (i) If in the reasonable opinion of counsel
                  to the Trust and the Company there is a question as to whether
                  the Exchange Offer is permitted by applicable law, the Trust
                  and the Company hereby agree to seek a no-action letter from
                  the Commission allowing the Trust and the Company to
                  Consummate an Exchange Offer for such Securities. The Trust
                  and the Company hereby agree to pursue the issuance of such a
                  decision to the Commission staff level but shall not be
                  required to take commercially unreasonable action to effect a
                  change of Commission policy. The Trust and the Company hereby
                  agree, however, to (A) participate in telephonic conferences
                  with the Commission, (B) deliver to the Commission staff an
                  analysis prepared by counsel to the Trust and the Company
                  setting forth the legal bases, if any, upon which such counsel
                  has
<PAGE>   10
                                                                               8

                  concluded that such an Exchange Offer should be permitted and
                  (C) diligently pursue a resolution (which need not be
                  favorable) by the Commission staff of such submission.

                                    (ii) As a condition to its participation in
                  the Exchange Offer pursuant to the terms of this Agreement,
                  each Holder of Transfer Restricted Securities shall furnish,
                  upon the request of the Trust or the Company, prior to the
                  Consummation thereof, a written representation to the Trust or
                  the Company (which may be contained in the letter of
                  transmittal contemplated by the Exchange Offer Registration
                  Statement) to the effect that (A) it is not an affiliate of
                  the Trust or the Company, (B) it is not engaged in, and does
                  not intend to engage in, and has no arrangement or
                  understanding with any person to participate in, a
                  distribution of the New Securities to be issued in the
                  Exchange Offer and (C) it is acquiring the New Securities in
                  its ordinary course of business. In addition, all such Holders
                  of Transfer Restricted Securities shall otherwise cooperate in
                  the Company's and the Trust's preparations for the Exchange
                  Offer. Each Holder hereby acknowledges and agrees that any
                  Broker-Dealer and any such Holder using the Exchange Offer to
                  participate in a distribution of the securities to be acquired
                  in the Exchange Offer (1) could not under Commission policy as
                  in effect on the date of this Agreement rely on the position
                  of the Commission enunciated in Morgan Stanley and Co., Inc.
                  (available June 5, 1991) and Exxon Capital Holdings
                  Corporation (available May 13, 1988), as interpreted in the
                  Commission's letter to Shearman & Sterling dated July 2, 1993,
                  and similar no-action letters (including any no-action letter
                  obtained pursuant to clause (i) above), and (2) must comply
                  with the registration and prospectus delivery requirements of
                  the Securities Act in connection with a secondary resale
                  transaction and that such a secondary resale transaction
                  should be covered by an effective registration statement
                  containing the selling security holder information required by
                  Item 507 or 508, as applicable, of Regulation S-K if the
                  resales are of New Securities obtained by such Holder in
                  exchange for Securities acquired by such Holder directly from
                  the Trust or the Company.

                                    (iii) Prior to effectiveness of the Exchange
                  Offer Registration Statement, the Company and the Trust shall
                  provide a supplemental letter to the Commission (A) stating
                  that the Company and the Trust are registering the Exchange
                  Offer in reliance on the position of the Commission enunciated
                  in Exxon Capital Holdings Corporation (available May 13,
                  1988), Morgan Stanley and Co., Inc. (available June 5, 1991)
                  and, if applicable, any no-action letter obtained pursuant to
                  clause (i) above and (B) including a representation that the
                  Company and the Trust have not entered into any arrangement or
                  understanding with any Person to distribute the New Securities
                  to be received in the Exchange Offer and that, to the best of
                  the Company's and the Trust's information and belief, based
                  only on written representations received under clause (ii)
                  above, that each Holder participating in the Exchange Offer is
                  acquiring the New Securities in its ordinary course of
                  business and has no arrangement or understanding with any
                  Person to participate in the distribution of the New
                  Securities received in the Exchange Offer.

                           (b) Shelf Registration Statement. In connection with
         any Shelf Registration Statement, the Company and the Trust shall
         comply with all the provisions of Section 6(c) below and shall use
         their best efforts to effect such registration to permit the sale of
         the Transfer Restricted Securities being sold in accordance with the
         intended method or methods of distribution thereof, and pursuant
         thereto the Company and the Trust will as expeditiously as possible
         prepare
<PAGE>   11
                                                                               9

         and file with the Commission a Registration Statement relating to the
         registration on any appropriate form under the Securities Act, which
         form shall be available for the sale of the Transfer Restricted
         Securities in accordance with the intended method or methods of
         distribution thereof.

                           (c) General Provisions. In connection with any
         Registration Statement and any Prospectus required by this Agreement to
         permit the sale or resale of Transfer Restricted Securities (including,
         without limitation, any Registration Statement and the related
         Prospectus required to permit resales of Securities by Broker-Dealers),
         the Company and the Trust shall:

                                    (i) use their best efforts to keep such
                  Registration Statement continuously effective and provide all
                  requisite financial statements for the period specified in
                  Section 3 or 4 of this Agreement, as applicable; upon the
                  occurrence of any event that would cause any such Registration
                  Statement or the Prospectus contained therein (A) to contain a
                  material misstatement or omission or (B) not to be effective
                  and usable for resale of Transfer Restricted Securities during
                  the period required by this Agreement, the Company and the
                  Trust shall file promptly an appropriate amendment to such
                  Registration Statement, in the case of clause (A), correcting
                  any such misstatement or omission, and, in the case of either
                  clause (A) or (B), use their best efforts to cause such
                  amendment to be declared effective and such Registration
                  Statement and the related Prospectus to become usable for
                  their intended purpose(s) as soon as practicable thereafter;

                                    (ii) prepare and file with the Commission
                  such amendments and post-effective amendments to the
                  Registration Statement as may be necessary to keep the
                  Registration Statement effective for the applicable period set
                  forth in Section 3 or 4 hereof, as applicable, or such shorter
                  period as will terminate when all Transfer Restricted
                  Securities covered by such Registration Statement have been
                  sold; cause the Prospectus to be supplemented by any required
                  Prospectus supplement, and as so supplemented to be filed
                  pursuant to Rule 424 under the Securities Act, and to comply
                  fully with the applicable provisions of Rules 424 and 430A
                  under the Securities Act in a timely manner; and comply with
                  the provisions of the Securities Act with respect to the
                  disposition of all securities covered by such Registration
                  Statement during the applicable period in accordance with the
                  intended method or methods of distribution by the sellers
                  thereof set forth in such Registration Statement or supplement
                  to the Prospectus;

                                    (iii) advise the underwriter(s), if any, and
                  selling Holders promptly and, if requested by such Persons, to
                  confirm such advice in writing, (A) when the Prospectus or any
                  Prospectus supplement or post-effective amendment has been
                  filed, and, with respect to any Registration Statement or any
                  post-effective amendment thereto, when the same has become
                  effective, (B) of any request by the Commission for amendments
                  to the Registration Statement or amendments or supplements to
                  the Prospectus or for additional information relating thereto,
                  (C) of the issuance by the Commission of any stop order
                  suspending the effectiveness of the Registration Statement
                  under the Securities Act or of the suspension by any state
                  securities commission of the qualification of the Transfer
                  Restricted Securities for offering or sale in any
                  jurisdiction, or the initiation of any proceeding for any of
                  the preceding purposes, and (D) of the existence of any fact
                  or the happening of any event that makes any statement of a
                  material fact made in the Registration Statement, the
                  Prospectus, any amendment or supplement thereto, or any

                                                                              10

                  document incorporated by reference therein untrue, or that
                  requires the making of any additions to or changes in the
                  Registration Statement or the Prospectus in order to make the
                  statements therein not misleading; provided that the Company
                  shall not be required to disclose the nature or substance of
                  any such fact or event as long as it is acting in good faith.
                  If at any time the Commission shall issue any stop order
                  suspending the effectiveness of the Registration Statement, or
                  any state securities commission or other regulatory authority
                  shall issue an order suspending the qualification or exemption
                  from qualification of the Transfer Restricted Securities under
                  state securities or Blue Sky laws, the Trust and the Company
                  shall use their best efforts to obtain the withdrawal or
                  lifting of such order at the earliest possible time;

                                    (iv) furnish to each of the selling or
                  exchanging Holders and each of the underwriter(s), if any,
                  before filing with the Commission, copies of any Shelf
                  Registration Statement or any Prospectus included therein or
                  any amendments or supplements to any such Shelf Registration
                  Statement or Prospectus (excluding all documents incorporated
                  by reference after the initial filing of such Registration
                  Statement), which documents will be subject to the review of
                  such Holders and underwriter(s), if any, for a period of at
                  least five business days, and the Trust and the Company will
                  not file any such Registration Statement or Prospectus or any
                  amendment or supplement to any such Registration Statement or
                  Prospectus to which a selling Holder of Transfer Restricted
                  Securities covered by such Registration Statement or the
                  underwriter(s), if any, shall reasonably object within such
                  five business days. A selling Holder or underwriter, if any,
                  shall be deemed to have reasonably objected to such filing if
                  such Registration Statement, amendment, Prospectus or
                  supplement, as applicable, as proposed to be filed, contains a
                  material misstatement or omission;

                                    (v) promptly after the filing of any
                  document that is to be incorporated by reference into a
                  Registration Statement or Prospectus, provide copies of such
                  document to the selling Holders and to the underwriter(s), if
                  any, and make the Trust's and the Company's representatives
                  available for discussion of such document and other customary
                  due diligence matters;

                                    (vi) make available at reasonable times for
                  inspection by the selling Holders, any underwriter
                  participating in any disposition pursuant to such Registration
                  Statement, and any attorney or accountant retained by such
                  selling Holders or any of the underwriter(s), all financial
                  and other records, pertinent corporate documents and
                  properties of the Trust and the Company and cause the Trust's
                  and the Company's officers, directors, managers and employees
                  to supply all information reasonably requested by any such
                  Holder, underwriter, attorney or accountant in connection with
                  such Registration Statement subsequent to the filing thereof
                  and prior to its effectiveness;

                                    (vii) if requested by any selling Holders
                  under the Shelf Registration Statement or the underwriter(s),
                  if any, promptly incorporate in any Shelf Registration
                  Statement or Prospectus, pursuant to a supplement or
                  post-effective amendment if necessary, such information as
                  such selling Holders and underwriter(s), if any, may
                  reasonably request to have included therein, including,
                  without limitation, information relating to the "Plan of
                  Distribution" of the Transfer Restricted Securities,

                  supplement or post-effective amendment as soon as practicable
                  after the Trust and the Company are notified of the matters to
                  be incorporated in such Prospectus supplement or
                  post-effective amendment;

                                    (viii) cause the Transfer Restricted
                  Securities covered by the Registration Statement (A) to be
                  rated with the appropriate rating agencies, if so requested by
                  the Holders of a majority in aggregate principal amount of
                  Securities covered thereby or the underwriter(s), if any, or
                  (B) if the Transfer Restricted Securities were previously
                  rated to reconfirm such ratings;

                                    (ix) furnish to each selling Holder and each
                  of the underwriter(s), if any, without charge, at least one

                  of the underwriter(s), if any, without charge, as many copies
                  of the Prospectus (including each preliminary prospectus) and
                  any amendment or supplement thereto as such Persons reasonably
                  may request; the Trust and the Company hereby consent to the
                  use of the Prospectus and any amendment or supplement thereto
                  by each of the selling Holders and each of the underwriter(s),
                  if any, in connection with the offering and the sale of the
                  Transfer Restricted Securities covered by the Prospectus or
                  any amendment or supplement thereto;

                                    (xi) enter into such agreements (including
                  an underwriting agreement), and make such representations and
                  warranties, and take all such other actions in connection

                  connection with an Underwritten Registration, the Trust and
                  the Company shall:

                                    the date thereof, such matters as such
                                    parties may reasonably request;

                                                     (2) an opinion, dated the

                                    effect that such counsel has participated in
                                    conferences with officers and other
                                    representatives of the
<PAGE>   14
                                                                              12

                                    Company and the Trust, representatives of
                                    the independent public accountants for the
                                    Company, the Initial Purchasers'
                                    representatives and the Initial Purchasers'
                                    counsel in connection with the preparation
                                    of such Registration Statement and the
                                    related Prospectus and have considered the
                                    matters required to be stated therein and
                                    the statements contained therein, although
                                    such counsel has not independently verified
                                    the accuracy, completeness or fairness of
                                    such statements; and that such counsel
                                    advises that, on the basis of the foregoing
                                    (relying as to materiality to a large extent
                                    upon facts provided to such counsel by
                                    officers and other representatives of the
                                    Company and the Trust and without
                                    independent check or verification), no facts
                                    came to such counsel's attention that caused
                                    such counsel to believe that the applicable
                                    Registration Statement, at the time such
                                    Registration Statement or any post-effective
                                    amendment thereto became effective,
                                    contained an untrue statement of a material
                                    fact or omitted to state a material fact
                                    required to be stated therein or necessary
                                    to make the statements therein not
                                    misleading, or that the Prospectus contained
                                    in such Registration Statement as of its
                                    date, contained an untrue statement of a
                                    material fact or omitted to state a material
                                    fact necessary in order to make the
                                    statements therein, in light of the
                                    circumstances under which they were made,
                                    not misleading. Without limiting the
                                    foregoing, such counsel may state further
                                    that such counsel assumes no responsibility
                                    for, and has not independently verified, the
                                    accuracy, completeness or fairness of the

                           parties to evidence compliance with clause (A) above
                           and with any customary conditions contained in the

                                    If at any time the representations and

                  Initial Purchasers and the underwriter(s), if any, and each
                  selling Holder promptly and, if requested by such Persons,
                  shall confirm such advice in writing;

                                    (xii) prior to any public offering of
                  Transfer Restricted Securities, cooperate with the selling
                  Holders, the underwriter(s), if any, and their respective
                  counsel in connection with the registration and qualification
                  of the Transfer Restricted Securities under the securities or
                  Blue Sky laws of such jurisdictions as the selling Holders or
                  underwriter(s) may reasonably request and do any and all other
                  acts or things necessary or advisable to enable the
                  disposition in such jurisdictions of the Transfer Restricted
                  Securities covered by the Shelf Registration Statement;
                  provided, however, that neither the Company nor the Trust
                  shall not be required to register or qualify as a foreign
                  corporation where it is not now so qualified or to take any
                  action that would subject it to the service of process in
                  suits or to taxation, other than as to matters and
                  transactions relating to the Registration Statement, in any
                  jurisdiction where it is not now so subject;

                                    (xiii) shall issue, upon the request of any
                  Holder of Securities covered by the Shelf Registration
                  Statement, New Securities in the same amount as the Securities
                  surrendered to the Company and the Trust by such Holder in
                  exchange therefor or being sold by such Holder; such New
                  Securities to be registered in the name of such Holder or in
                  the name of the purchaser(s) of such Securities, as the case
                  may be; in return, the Securities held by such Holder shall be
                  surrendered to the Company and the Trust for cancellation;

                                    (xiv) cooperate with the selling Holders and
                  the underwriter(s), if any, to facilitate the timely
                  preparation and delivery of certificates representing Transfer
                  Restricted Securities to be sold and not bearing any
                  restrictive legends; and enable such Transfer Restricted
                  Securities to be in such denominations and registered in such
                  names as the Holders or the underwriter(s), if any, may
                  request at least two business days prior to any sale of
                  Transfer Restricted Securities made by such underwriter(s);

                                    (xv) if any fact or event contemplated by
                  clause (c)(iii)(D) above shall exist or have occurred, as
                  promptly as is practicable under the circumstances in the good
                  faith determination of the Company prepare a supplement or
                  post-effective amendment to the Registration Statement or
                  related Prospectus or any document incorporated therein by
                  reference or file any other required document so that, as
                  thereafter delivered to the purchasers of Transfer Restricted
                  Securities, the Registration Statement will not contain an
                  untrue statement of a material fact or omit to state any
                  material fact necessary to make the statements therein not
                  misleading; and any Prospectus will not contain an untrue
                  statement of a material fact or omit to state any material
                  fact necessary to make the statements therein, in light of the
                  circumstances under which they were made, not misleading;

                                    (xvi) provide CUSIP numbers for all Transfer
                  Restricted Securities not later than the effective date of the
                  Registration Statement and provide certificates for the
                  Transfer Restricted Securities;

                                    (xvii) cooperate and assist in any filings
                  required to be made with the NASD and in the performance of
                  any due diligence investigation by any underwriter (including
                  any "qualified independent underwriter") that is required to
                  be retained in accordance with the rules and regulations of
                  the NASD, and use its best efforts to cause such Registration
                  Statement to become effective and approved by such
                  governmental
<PAGE>   16
                                                                              14

                  agencies or authorities as may be necessary to enable the
                  Holders selling Transfer Restricted Securities to consummate
                  the disposition of such Transfer Restricted Securities;

                                    (xviii) otherwise use its best efforts to
                  comply with all applicable rules and regulations of the
                  Commission, and make generally available to its security
                  holders, as soon as practicable, a consolidated earnings
                  statement meeting the requirements of Rule 158 (which need not
                  be audited) for the twelve-month period (A) commencing at the
                  end of any fiscal quarter in which Transfer Restricted
                  Securities are sold to underwriters in a firm or best efforts
                  Underwritten Offering or (B) if not sold to underwriters in
                  such an offering, beginning with the first month of the
                  Company's first fiscal quarter commencing after the effective
                  date of the Registration Statement;

                                    (xix) cause the Indenture, the Guarantee and
                  the Declaration to be qualified under the TIA not later than
                  the effective date of the first Registration Statement
                  required by this Agreement, and, in connection therewith,
                  cooperate with the applicable trustees and the Holders of
                  Securities to effect such changes to the Indenture, the
                  Guarantee and the Declaration as may be required for the
                  Indenture, the Guarantee and the Declaration to be so
                  qualified in accordance with the terms of the TIA; and
                  execute, and use their best efforts to cause the Indenture
                  Trustee, Guarantee Trustee and the Property Trustee to
                  execute, all documents that may be required to effect such
                  changes and all other forms and documents required to be filed
                  with the Commission to enable such Indenture to be so
                  qualified in a timely manner; and

                                    (xx) provide promptly to each Holder upon
                  request each document filed with the Commission pursuant to
                  the requirements of Section 13(a) and Section 15(d) of the
                  Exchange Act.

                           Each Holder agrees by acquisition of a Transfer
         Restricted Security that, upon receipt of any notice from the Company
         or the Trust of the existence of any fact or event of the kind
         described in Section 6(c)(iii)(D) hereof, such Holder will forthwith
         discontinue disposition of Transfer Restricted Securities pursuant to
         the applicable Registration Statement until such Holder's receipt of
         the copies of the supplemented or amended Prospectus contemplated by
         Section 6(c)(xvi) hereof, or until it is advised in writing (the
         "Advice") by the Company or the Trust that the use of the Prospectus
         may be resumed, and has received copies of any additional or
         supplemental filings that are incorporated by reference in the
         Prospectus. If so directed by the Company or the Trust, each Holder
         will deliver to the Company or the Trust (at the Company's and the
         Trust's expense) all copies, other than permanent file copies then in
         such Holder's possession, of the Prospectus covering such Transfer
         Restricted Securities that was current at the time of receipt of such
         notice. In the event the Company or the Trust shall give any such
         notice, the time period regarding the effectiveness of such
         Registration Statement set forth in Section 3 or 4 hereof, as
         applicable, shall be extended by the number of days during the period
         from and including the date of the giving of such notice pursuant to
         Section 6(c)(iii)(D) hereof to and including the date when each selling
         Holder covered by such Registration Statement shall have received the
         copies of the supplemented or amended Prospectus contemplated by
         Section 6(c)(xvi) hereof or shall have received the Advice.

                  7. Registration Expenses.

                           All expenses incident to the Company's and the
         Trust's performance of or compliance with this Agreement, other than
         the expenses of any Holder, will be borne by the Company and the Trust,
         regardless of whether a Registration Statement becomes effective,
         including without limitation: (i) all registration and filing fees and
         expenses (including filings made by any Holder with the NASD (and, if
         applicable, the fees and expenses of any "qualified independent
         underwriter" and its counsel that may be required by the rules and
         regulations of the NASD)); (ii) all fees and expenses of compliance
         with federal securities and state Blue Sky or securities laws; (iii)
         all expenses of printing (including printing certificates for the New

         and the Trust; (v) all application and filing fees in connection with

         disbursements of independent certified public accountants of the
         Company and the Trust (including the expenses of any special audit and
         comfort letters required by or incident to such performance); and (vii)
         in the event a Shelf Registration Statement shall be filed, shall bear
         or reimburse the Holders of the Transfer Restricted Securities covered
         thereby for the reasonable fees and disbursements of one firm of
         counsel designated by the Holders of a majority in principal amount of
         the Transfer Restricted Securities covered thereby to act as counsel
         for the Holders of Transfer Restricted Securities in connection
         therewith.

                           The Company and the Trust will, in any event, bear
         their internal expenses (including, without limitation, all salaries
         and expenses of their officers and employees performing legal or
         accounting duties), the expenses of any annual audit and the fees and
         expenses of any Person, including special experts, retained by the
         Company or the Trust.

                  8. Indemnification and Contribution.

                  (a) In connection with a Shelf Registration Statement or in
connection with any delivery of a Prospectus contained in an Exchange Offer
Registration Statement by any participating Broker-Dealer or Initial Purchaser,
as applicable, who seeks to sell New Securities, the Company and the Trust shall
indemnify and hold harmless each Holder of Transfer Restricted Securities
included within any such Shelf Registration Statement and each participating
Broker-Dealer or Initial Purchaser selling New Securities, and each person, if
any, who controls any such person within the meaning of Section 15 of the
Securities Act (each, a "Participant") from and against any loss, claim, damage
or liability, joint or several, or any action in respect thereof (including, but
not limited to, any loss, claim, damage, liability or action relating to
purchases and sales of Securities) to which such Participant or controlling
person may become subject, under the Securities Act or otherwise, insofar as
such loss, claim, damage, liability or action arises out of, or is based upon,
(i) any untrue statement or alleged untrue statement of a material fact
contained in any such Registration Statement or any prospectus forming part
thereof or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and shall reimburse
each Participant promptly upon demand for any legal or other expenses reasonably
incurred by such Participant in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action as
such expenses are incurred; provided, however, that (i) the Company and the
Trust shall not be liable in any such case to the extent that any such loss,
claim, damage, liability or action arises out of, or is based upon, any untrue
statement or alleged untrue statement or omission or alleged omission made in
any such Registration Statement or any prospectus forming part thereof or in any
such
<PAGE>   18
                                                                              16

amendment or supplement in reliance upon and in conformity with written
information furnished to the Company and the Trust by or on behalf of any
Participant specifically for inclusion therein; and provided further that as to
any preliminary Prospectus, the indemnity agreement contained in this Section
8(a) shall not inure to the benefit of any such Participant or any controlling
person of such Participant on account of any loss, claim, damage, liability or
action arising from the sale of the New Securities to any person by that
Participant if (i) that Participant failed to send or give a copy of the
Prospectus, as the same may be amended or supplemented, to that person within
the time required by the Securities Act and (ii) the untrue statement or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact in such preliminary Prospectus was corrected in the Prospectus,
unless, in each case, such failure resulted from non-compliance by the Company
and the Trust with Section 6(c). The foregoing indemnity agreement is in
addition to any liability which the Company and the Trust may otherwise have to
any Participant or to any controlling person of that Participant.

                  (b) Each Participant, severally and not jointly, shall
indemnify and hold harmless the Company and the Trust, each of its directors,
officers, employees or agents and each person, if any, who controls the Company
and the Trust within the meaning of Section 15 of the Securities Act, from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof, to which the Company and the Trust or any such director,
officer, employees or agents or controlling person may become subject, under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in any preliminary Prospectus,
Registration Statement or Prospectus or in any amendment or supplement thereto
or (ii) the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, but in each case only to the extent that the untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company and the
Trust by or on behalf of such Participant specifically for inclusion herein, and
shall reimburse the Company and the Trust and any such director, officer,
employees or agents or controlling person for any legal or other expenses
reasonably incurred by the Company and the Trust or any such director, officer,
employees or agents or controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred. The foregoing indemnity agreement is in
addition to any liability which any Participant may otherwise have to the
Company and the Trust or any such director, officer or controlling person.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 8 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 8.
If any such claim or action shall be brought against an indemnified party, and
it shall have notified the indemnifying party thereof, the indemnifying party
shall be entitled to participate therein and, to the extent that it wishes,
jointly with any other similarly notified indemnifying party, to assume the
defense thereof with counsel satisfactory to the indemnified party. After notice
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, the indemnifying party shall not be liable
to the indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the Participants shall have the right to employ counsel to represent them and
their respective officers,
<PAGE>   19
                                                                              17

employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought by the Participants
against the Company and the Trust under this Section 8 if, in the reasonable
judgment of the Participants it is advisable for the Participants and their
officers, employees and controlling persons to be represented by separate
counsel, and in that event the fees and expenses of such separate counsel shall
be paid by the Trust and the Company. Each indemnified party, as a condition of
the indemnity agreements contained in Section 8, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall (i) without the prior written consent of the
indemnified parties (which consent shall not be unreasonably withheld), settle
or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final
judgment of the plaintiff in any such action, the indemnifying party agrees to
indemnify and hold harmless any indemnified party from and against any loss of
liability by reason of such settlement or judgment.

                  (d) If the indemnification provided for in this Section 8
shall for any reason be unavailable to or insufficient to hold harmless an
indemnified party under Section 8(a) or 8(b) in respect of any loss, claim,
damage or liability, or any action in respect thereof, referred to therein, then
each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the exchange of the Securities pursuant to
the Registered Exchange Offer, or (ii) if the allocation provided by the
foregoing clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the indemnifying party on the one hand
and the indemnified party on the other with respect to the statements or
omissions which resulted in such loss, claim, damage or liability, or action in
respect thereof, as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Trust and the Company or
the Participants, the intent of the parties and their relative knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The Company and the Trust and the Participants agree that it would not be just
and equitable if contributions pursuant to this Section 8(d) were to be
determined by pro rata allocation (even if the Participants were treated as one
entity for such purpose) or by any other method of allocation which does not
take into account the equitable considerations referred to herein. The amount
paid or payable by an indemnified party as a result of the loss, claim, damage
or liability, or action in respect thereof, referred to above in this Section
8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 8(d), no Participant shall be required to contribute
any amount in excess of the amount by which the net proceeds received by such
Participant from an offering of the Notes exceeds the amount of any damages
which such Participant has otherwise paid or become liable to pay by reason of
any untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Participants'
obligations to contribute as provided in this Section 8(d) are several and not
joint.

                  9. Rule 144A.

                  The Company and the Trust hereby agrees with each Holder, for
so long as any Transfer Restricted Securities remain outstanding, to make
available to any Holder or beneficial owner of Transfer Restricted Securities in
connection with any sale thereof and any prospective purchaser of such Transfer
Restricted Securities from such Holder or beneficial owner, upon request, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Transfer Restricted Securities pursuant to Rule 144A.

                  10. Participation in Underwritten Registrations.

                  No Holder may participate in any Underwritten Registration
hereunder unless such Holder (a) agrees to sell such Holder's Transfer
Restricted 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, lockup letters and other documents
required under the terms of such underwriting arrangements.

                  11. Selection of Underwriters.

                  The Holders of Transfer Restricted Securities covered by the
Shelf Registration Statement who desire to do so may sell such Transfer
Restricted Securities in an Underwritten Offering. In any such Underwritten
Offering, the investment banker or investment bankers and manager or managers
that will administer the offering will be selected by the Holders of a majority
in aggregate principal amount of the Transfer Restricted Securities included in
such offering; provided, that such investment bankers and managers must be
reasonably satisfactory to the Company.

                  12. Miscellaneous.

                           (a) Remedies. The Company and the Trust agree that
         monetary damages (including the Additional Interest and Additional
         Distributions contemplated hereby) would not be adequate compensation
         for any loss incurred by reason of a breach by it of the provisions of
         this Agreement and hereby agree to waive the defense in any action for
         specific performance that a remedy at law would be adequate.

                           (b) No Inconsistent Agreements. The Company and the
         Trust will not on or after the date of this Agreement enter into any
         agreement with respect to their securities that is inconsistent with
         the rights granted to the Holders in this Agreement or otherwise
         conflicts with the provisions hereof. The Company and the Trust have
         not previously entered into any agreement granting any registration
         rights with respect to their securities to any Person. 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
         Trust's and the Company's securities under any agreement in effect on
         the date hereof.

                           (c) Adjustments Affecting the Securities. The Company
         and the Trust will not take any action, or permit any change to occur,
         with respect to the Securities that would materially and adversely
         affect the ability of the Holders to Consummate any Exchange Offer.

                           (d) Amendments and Waivers. The provisions of this
         Agreement may not be amended, modified or supplemented, and waivers or
         consents to or departures from the
<PAGE>   21
                                                                              19

         provisions hereof may not be given, unless the Company and the Trust
         have obtained the written consent of Holders of a majority of the
         outstanding principal amount of Transfer Restricted Securities.
         Notwithstanding the foregoing, a waiver or consent to departure from
         the provisions hereof that relates exclusively to the rights of Holders
         whose Securities are being tendered pursuant to the Exchange Offer and
         that does not affect directly or indirectly the rights of other Holders
         whose Securities are not being tendered pursuant to such Exchange Offer
         may be given by the Holders of a majority of the outstanding principal
         amount of Transfer Restricted Securities being tendered or registered.

         of each of the parties, including without limitation and without the

         inure to the benefit of or be binding upon a successor or assign of a
         Holder unless and to the extent such successor or assign acquired
         Transfer Restricted Securities from such Holder.

                           (g) Counterparts. This Agreement may be executed in

                           (i) Governing Law. THIS AGREEMENT SHALL BE GOVERNED
         BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK,
         WITHOUT REGARD TO THE CONFLICTS OF LAW RULES THEREOF.

                           (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) Entire Agreement. This Agreement together with
         the other transaction documents is intended by the parties as a final
         expression of their agreement and intended to be a complete and
         exclusive statement of the agreement and understanding of the parties
         hereto in respect of the subject matter contained herein. There are no
         restrictions, promises, warranties or undertakings, other than those
         set forth or referred to herein with respect to the registration rights
         granted by the Company and the Trust with respect to the Transfer
         Restricted Securities. This Agreement supersedes all prior agreements

         matter.

         approval of Holders of a specified percentage of Transfer Restricted
         Securities is required hereunder, Transfer Restricted Securities held
         by the Company 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.

behalf of the Trust for the benefit of the Holders of the Securities, and the
Guarantee Trustee shall not transfer this Guarantee to any Person except a
Holder of Securities exercising his or her rights pursuant to Section 5.4(b) or

Guarantee Trustee shall enforce this Guarantee for the benefit of the Holders of
the Securities.

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

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

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

                                    (A) the duties and obligations of the
                           Guarantee Trustee shall be determined solely by the
                           express provisions of this Guarantee, and the
                           Guarantee Trustee shall not be liable except for the
                           performance of such duties and obligations as are
                           specifically set forth in this Guarantee, and no
                           implied covenants or obligations shall be read into
                           this Guarantee against the Guarantee Trustee; and

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

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

                                                                               9

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

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

                  Trustee (unless other evidence is herein specifically
                  prescribed) may, in the absence of bad faith on its part,
                  request and conclusively rely upon an Officers' Certificate

                  thereof);

                                    (v) The Guarantee Trustee may consult with
                  counsel, and the advice or opinion of such counsel with

                                                                              10

                  opinion. Such counsel may be counsel to the Guarantor or any
                  of its Affiliates and may include any of its employees. The
                  Guarantee Trustee shall have the right at any time to seek
                  instructions concerning the administration of this Guarantee

                  obligation to exercise any of the rights or powers vested in
                  it by this Guarantee at the request or direction of any
                  Holder, unless such Holder shall have provided to the
                  Guarantee Trustee such security and indemnity, reasonably
                  satisfactory to the Guarantee Trustee, against the costs,
                  expenses (including attorneys' fees and expenses and the
                  expenses of the Guarantee Trustee's agents, nominees or
                  custodians) and liabilities that might be incurred by it in
                  complying with such request or direction, including such
                  reasonable advances as may be requested by the Guarantee
                  Trustee; provided, that nothing contained in this Section
                  3.2(a)(vi) shall be taken to relieve the Guarantee Trustee,
                  upon the occurrence of a Guarantee Event of Default, of its
                  obligation to exercise the rights and powers vested in it by
                  this Guarantee;

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

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

                                    (ix) Any action taken by the Guarantee
                  Trustee or its agents hereunder shall bind the Holders of the
                  Securities, and the signature of the Guarantee Trustee or its
                  agents alone shall be sufficient and effective to perform any
                  such action. No third party shall be required to inquire as to
                  the authority of the Guarantee Trustee to so act or as to its
                  compliance with any of the terms and provisions of this
                  Guarantee, both of which shall be conclusively evidenced by
                  the Guarantee Trustee's or its agent's taking such action; and

                                    (x) Whenever in the administration of this
                  Guarantee the Guarantee Trustee shall deem it desirable to
                  receive instructions with respect to enforcing any remedy or
                  right or taking any other action hereunder, the Guarantee
                  Trustee (i) may request instructions from the Holders of a
                  Majority in Liquidation Amount of the Securities, (ii) may
                  refrain from enforcing such remedy or right or taking such
                  other action until such instructions are received,
<PAGE>   15
                                                                              11

                  and (iii) shall be protected in conclusively relying on or
                  acting in accordance with such instructions.

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

                  SECTION 3.3 Not Responsible for Recitals or Issuance of
Guarantee. The recitals contained in this Guarantee shall be taken as the
statements of the Guarantor, and the Guarantee Trustee does not assume any
responsibility for their correctness. The Guarantee Trustee makes no
representations as to the validity or sufficiency of this Guarantee.

                  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 Person permitted by the Securities and
                  Exchange Commission to act as an institutional trustee under
                  the Trust Indenture Act, 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 District of Columbia authority. If such
                  corporation publishes reports of condition at least annually,
                  pursuant to law or to the requirements of the supervising or
                  examining authority referred to above, then, for the purposes
                  of this Section 4.1(a)(ii), the combined capital and surplus
                  of such corporation shall be deemed to be its combined capital
                  and surplus as set forth in its most recent report of
                  condition so published.

                  (b) If at any time the Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Guarantee Trustee shall immediately
resign in the manner and with the effect set out in Section 4.2(b).
<PAGE>   16
                                                                              12

                  (c) If the Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Guarantee Trustee and Guarantor shall in all respects comply
with the provisions of Section 310(b) of the Trust Indenture Act.

                  SECTION 4.2 Appointment, Removal and Resignation of Guarantee
Trustee.

                  (a) Subject to Section 4.1(b), the Guarantee Trustee may be
appointed or removed with or without cause at any time by the Guarantor. No
resignation or removal of the Guarantee Trustee and no appointment of a
Successor Guarantee Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the Successor Guarantee Trustee by
written instrument executed by the Successor Guarantee Trustee and delivered to
the Holders and the Guarantee Trustee.

                  (b) The Guarantee Trustee appointed to office shall hold such
office until a Successor Guarantee Trustee shall have been appointed or until
its removal or resignation.

                  (c) Subject to the immediately preceding paragraph, a
Guarantee Trustee may resign at any time by giving written notice thereof to the
Holders and the Guarantor, which resignation shall not take effect until a
Successor Guarantee Trustee has been appointed and has accepted such appointment
by instrument in writing executed by such Successor Guarantee Trustee and
delivered to the Guarantor and the resigning Guarantee Trustee.

                  (d) If no Successor Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 30
days after delivery to the Guarantor of an instrument of removal or resignation,
the removed or resigning Guarantee Trustee may petition any court of competent
jurisdiction for the appointment of a Successor Guarantee Trustee. Such court
may thereupon, after prescribing such notice, if any, as it may deem proper,
appoint a Successor Guarantee Trustee.

                  (e) No Guarantee Trustee shall be liable for the acts or
omissions to act of any Successor Guarantee Trustee.

                  (f) Upon termination of this Guarantee or removal or
resignation of the Guarantee Trustee pursuant to this Section 4.2, the Guarantor
shall pay to the Guarantee Trustee all amounts owing for fees and reimbursement
of expenses which have accrued to the date of such termination, removal or
resignation.

                  (g) The Guarantor shall promptly notify the Holders of the
resignation, removal or appointment of the Guarantee Trustee.

                                                                              13

                                    ARTICLE 5

                                    GUARANTEE

                  SECTION 5.1 Guarantee.

                  The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Trust), as and when due, regardless of any defense,
right of set-off or counterclaim that the Trust may have or assert. The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Trust to pay such amounts to the Holders. If a Trust Enforcement Event has
occurred and is continuing, the rights of holders of the Common Securities to
receive payments under this Guarantee are subordinated to the rights of Holders
of Capital Securities to receive Guarantee Payments under this Guarantee.

                  SECTION 5.2 Waiver of Notice and Demand.

                  The Guarantor hereby waives notice of acceptance of this
Guarantee and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the Trust or
any other Person before proceeding against the Guarantor, protest, notice of
nonpayment, notice of dishonor, notice of redemption and all other notices and
demands. Notwithstanding anything to the contrary herein, the Guarantor retains
all of its rights under the Indenture to extend the interest payment period on
the Debentures and the Guarantor shall not be obligated hereunder to make any
Guarantee Payments during any Extension Period (as defined in the Indenture)
with respect to the Distributions (as defined in the Declaration) on the
Securities.

                  SECTION 5.3 Obligations Not Affected.

                  The obligations, covenants, agreements and duties of the
Guarantor under this Guarantee shall be absolute and unconditional and shall
remain in full force and effect until the entire liquidation amount of all
outstanding Securities shall have been paid and such obligation shall in no way
be affected or impaired by reason of the happening from time to time of any
event, including without limitation, the following, whether or not with notice
to, or the consent of, the Guarantor:

                  (a) The release or waiver, by operation of law or otherwise,
         of the performance or observance by the Trust of any express or implied
         agreement, covenant, term or condition relating to the Securities to be
         performed or observed by the Trust;

                  (b) The extension of time for the payment by the Trust of all
         or any portion of the Distributions, Redemption Price (as defined in
         the Indenture), Liquidation Distribution or any other sums payable
         under the terms of the Securities or the extension of time for the
         performance of any other obligation under, arising out of, or
<PAGE>   18
                                                                              14

         in connection with the 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);

                  (c) Any failure, omission, delay or lack of diligence on the
         part of the Property Trustee or the Holders to enforce, assert or
         exercise any right, privilege, power or remedy conferred on the
         Property Trustee or the Holders pursuant to the terms of the
         Securities, or any action on the part of the Trust 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 Trust or any of the assets of the Trust;

                  (e) Any invalidity of, or defect or deficiency in, the
         Securities;

                  (f) The settlement or compromise of any obligation guaranteed
         hereby or hereby incurred; or

                  (g) 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 hereunder shall be absolute and unconditional under any and
         all circumstances.

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

                  No setoff, counterclaim, reduction or diminution of any
obligation, or any defense of any kind or nature that the Guarantor has or may
have against any Holder shall be available hereunder to the Guarantor against
such Holder to reduce the payments to it under this Guarantee.

                  SECTION 5.4 Rights of Holders.

                  (a) The Holders of a Majority in Liquidation Amount of the
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of this
Guarantee or exercising any trust or power conferred upon the Guarantee Trustee
under this Guarantee.

                  (b) If the Guarantee Trustee fails to enforce this Guarantee,
then any Holder of Securities may, subject to the subordination provisions of
Section 6.2, institute a legal proceeding directly against the Guarantor to
enforce the Guarantee Trustee's rights under this Guarantee without first
instituting a legal proceeding against the Trust, the Guarantee Trustee or any
other person or entity. Notwithstanding the foregoing, if the Guarantor has
failed to
<PAGE>   19
                                                                              15

make a Guarantee Payment, a Holder of Securities may, subject to the
subordination provisions of Section 6.2, directly institute a proceeding against
the Guarantor for enforcement of the Guarantee for such payment to the Holder of
the Securities of the principal of or interest on the Debentures on or after the
respective due dates specified in the Debentures, and the amount of the payment
will be based on the Holder's pro rata share of the amount due and owing on all
of the Securities. The Guarantor hereby waives any right or remedy to require
that any action on this Guarantee be brought first against the Trust or any
other person or entity before proceeding directly against the Guarantor.

                  SECTION 5.5 Guarantee of Payment.

                  This 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 of Securities against the Trust in respect of any amounts paid to
such Holders by the Guarantor under this 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 of any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Guarantee, if at the time of any such payment,
any amounts are due and unpaid under this 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
Guarantee Trustee for the benefit of the Holders.

                  SECTION 5.7 Independent Obligations.

                  The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Trust with respect to the Securities, and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee notwithstanding the
occurrence of any event referred to in subsections 5.3(a) through 5.3(g),
inclusive, hereof.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

                  SECTION 6.1 Limitation of Transactions.

                  So long as any Securities remain outstanding, if there shall
have occurred a Guarantee Event of Default or a Trust Enforcement Event, then
the Guarantor shall not, and shall not permit any subsidiary of the Guarantor,
to (i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, the Guarantor's capital
stock or (ii) make any payment of principal, interest or premium, if

                                                                              16

any, on or repay, repurchase or redeem any debt securities of the Guarantor that
rank pari passu with or junior to the Debentures or make any guarantee payments
with respect to any guarantee by the Guarantor of the debt securities of any
subsidiary of the Guarantor if such guarantee ranks pari passu with or junior to
the Debentures (other than (a) repurchases, redemptions or other acquisitions of
shares of capital stock of the Guarantor in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of
any one or more employees, officers, directors or consultants or in connection
with a dividend reinvestment or stockholder stock purchase plan, (b) as a result

Guarantor's indebtedness for any class or series of the Guarantor's capital
stock, (c) the purchase of fractional interests in shares of the Guarantor's
capital stock pursuant to the conversion or exchange provisions of such capital

dividend in the form of stock, warrants, options or other rights where the
dividend stock or the stock issuable upon exercise of such warrants, options or
other rights is the same stock as that on which the dividend is being paid (or
pari passu with or junior to such stock).

                  SECTION 6.2 Ranking.

                  This Guarantee will constitute an unsecured obligation of the
Guarantor and will rank subordinate and junior in right of payment to all other
liabilities of the Guarantor, except those liabilities of the Guarantor made
pari passu or subordinate by their express terms.

                  If a Trust Enforcement Event has occurred and is continuing
under the Declaration, the rights of the holders of the Common Securities to
receive Guarantee Payments hereunder shall be subordinated to the rights of the
holders of the Capital Securities to receive payment of all amounts due and
owing hereunder.

                                    DUE 2027


                          CALCULATION AGENCY AGREEMENT
                                    BETWEEN
                             STAR BANC CORPORATION
                                      AND
                       THE FIRST NATIONAL BANK OF CHICAGO
                            DATED AS OF JUNE 8, 1997



            STAR BANC CORPORATION, an Ohio corporation (the "Corporation"), will
issue and sell, in one or more issuances and sales, certain of its securities
designated as Floating Rate Junior Subordinated Debentures due 2027
("Debentures"). The Debentures will be issued under an Indenture, dated as of
June 8, 1997 (the "Indenture"), between the Corporation and The First National
Bank of Chicago, as Trustee (the "Trustee"). The Debentures, when issued and
sold, will be purchased by Star Capital I, a newly formed Delaware business
trust. Terms used but not defined herein shall have the meanings assigned to
them in the Declaration (as defined in the Indenture) and the Indenture.

            For the purpose of appointing an agent to calculate the interest
rate, based on LIBOR, on the Debentures, the Corporation and The First National
Bank of Chicago agree as follows:

            1. Upon the terms and subject to the conditions contained herein,
the Corporation hereby appoints The First National Bank of Chicago as its agent
(in such capacity, the "Calculation Agent") for the purpose of calculating the
interest rates on the Debentures in the manner and at the times provided in the
Indenture and the provisions of this Agreement.

            2. The Calculation Agent shall exercise due care to determine the
interest rate on the Debentures with respect to each interest period and shall
communicate the same, together with the amount of interest to be paid in respect
of such interest period and the relevant interest payment date, to the
Corporation, the Trustee, The Depository Trust Company and any paying agent
identified to it in writing as soon as practicable after each determination. The
Calculation Agent will, upon the request of the holder of any Debenture, provide
the interest rate then in effect with respect to such Debenture and, if
determined, the interest rate with respect to such Debenture which will become
effective on the next interest reset date. No amendment to the provisions of the
administrative procedures relating to the duties or obligations of the
Calculation Agent hereunder may become effective without the prior written
consent of the Calculation Agent, which consent shall not be unreasonably
withheld.

                                                                               2


            3. The Calculation Agent accepts its obligations set forth herein,
upon the terms and subject to the conditions hereof, including the following, to
all of which the Corporation agrees:

            (a) The Calculation Agent shall be entitled to such compensation as
may be agreed upon with the Corporation for all services rendered by the
Calculation Agent, and the Corporation promises to pay such compensation and to
reimburse the Calculation Agent for the reasonable out-of-pocket expenses
(including attorney's and other professional's fees and expenses) incurred by it
in connection with the services rendered by it hereunder upon receipt of such
invoices as the Corporation shall reasonably require. The Corporation also
agrees to indemnify the Calculation Agent for, and to hold it harmless against,
any and all loss, liability, damage, claim or expense (including the costs and
expenses of defending against any claim of liability) incurred by the
Calculation Agent that arises out of or in connection with its accepting
appointment as, or acting as, Calculation Agent hereunder, except such as may
result from the negligence, willful misconduct or bad faith of the Calculation
Agent or any of its agents or employees. The Calculation Agent shall incur no
liability and shall be indemnified and held harmless by the Corporation for, or
in respect of, any actions taken, omitted to be taken or suffered to be taken in
good faith by the Calculation Agent in reliance upon (i) the opinion or advice
of legal or other professional advisors satisfactory to it or (ii) written
instructions from the Corporation. The Calculation Agent shall not be liable for
any error resulting from the use of or reliance on a source of information used
in good faith and with due care to calculate any interest rate hereunder. The
provisions of this Section shall survive the termination of this Agreement and
the resignation or removal of the Calculation Agent.

            (b) In acting under this Agreement and in connection with the
Debentures, the Calculation Agent is acting solely as agent of the Corporation
and does not assume any obligations or relationship of agency or trust for or
with any of the owners or holders of the Debentures.

            (c) The Calculation Agent shall be protected and shall incur no
liability for or in respect of any action taken or omitted to be taken or
anything suffered by it in reliance upon the terms of the Debentures, any
notice, direction, certificate, affidavit, statement or other paper, document or
communication reasonably believed by it to be genuine and to have been approved
or signed by the proper party or parties.

            (d) The Calculation Agent, its officers, directors, employees and
shareholders may become the owners of, or acquire any interest in, any
Debentures, with the same rights that it or they would have if it were not the
Calculation Agent, and may engage or be interested in any financial or other
transaction with the Corporation as freely as if it were not the Calculation
Agent.

            (e) Neither the Calculation Agent nor its officers, directors,
employees, agents or attorneys shall be liable to the Corporation for any act or
omission hereunder, or for any error of judgment made in good faith by it or
them, except in the case of its or their negligence or willful misconduct.

                                                                               3


            (f) The Calculation Agent may consult with counsel (and such counsel
may be counsel to the Corporation or any of its affiliates and may include any
of its employees) and the written advice of such counsel or any opinion of
counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon.

            (g) The Calculation Agent shall be obligated to perform such duties
and only such duties as are herein specifically set forth, and no implied duties
or obligations shall be read into this Agreement against the Calculation Agent.

            (h) Unless herein otherwise specifically provided, any order,
certificate, notice, request, direction or other communication from the
Corporation made or given by it under any provision of this Agreement shall be
sufficient if signed by any officer of the Corporation.

            (i) The Calculation Agent may, upon obtaining the prior written
consent of the Corporation, perform any duties hereunder either directly or by
or through agents or attorneys, and the Calculation Agent shall not be
responsible for any misconduct or negligence on the part of any agent or
attorney appointed with due care by it hereunder.

            (j) The Corporation will not, without first obtaining the prior
written consent of the Calculation Agent, make any change to the Debentures, a
form of which is attached as an exhibit to the Indenture, if such change would
materially and adversely affect the Calculation Agent's duties and obligations
under this Agreement.

            4. (a) The Calculation Agent may at any time resign as Calculation
Agent by giving written notice to the Corporation of such intention on its part,
specifying the date on which its desired resignation shall become effective;
provided, however, that such date shall never be earlier than 30 days after the
receipt of such notice by the Corporation, unless the Corporation agrees to
accept less notice. The Calculation Agent may be removed at any time by the
filing with it of any instrument in writing signed on behalf of the Corporation
and specifying such removal and the date when it is intended to become
effective. Such resignation or removal shall take effect upon the date of the
appointment by the Corporation, as hereinafter provided, of a successor
Calculation Agent. If within 30 days after notice of resignation or removal has
been given, a successor Calculation Agent has not been appointed, the
Calculation Agent may petition a court of competent jurisdiction to appoint a
successor Calculation Agent. A successor Calculation Agent shall be appointed by
the Corporation by an instrument in writing signed on behalf of the Corporation
and the successor Calculation Agent. Upon the appointment of a successor
Calculation Agent and acceptance by it of such appointment, the Calculation
Agent so superseded shall cease to be such Calculation Agent hereunder. Upon its
resignation or removal, the Calculation Agent shall be entitled to the payment
by the Corporation of its compensation, if any is owed to it, for services
rendered hereunder and to the reimbursement of all reasonable out-of-pocket
expenses incurred in connection with the services rendered by it hereunder.

            (b) Any successor Calculation Agent appointed hereunder shall
execute and deliver to its predecessor and to the Corporation an instrument
accepting such appointment hereunder, and thereupon such successor Calculation
Agent, without any further act, deed or conveyance, shall become vested with all
the authority, rights, powers, trusts, immunities, duties and obligations of
such predecessor with like effect as if originally named as such Calculation
Agent hereunder, and such predecessor, upon payment of its charges and
disbursements then unpaid, shall thereupon become obliged to transfer and
deliver, and such successor Calculation Agent shall be entitled to receive,
copies of any relevant records maintained by such predecessor Calculation Agent.

            (c) Any corporation into which the Calculation Agent may be merged,
or any corporation with which the Calculation Agent may be merged, or any
corporation with which the Calculation Agent may be consolidated, or any
corporation resulting from any merger or consolidation to which the Calculation
Agent shall sell or otherwise transfer all or substantially all of its assets
and business shall, to the extent permitted by applicable law, be the successor
Calculation Agent under this Agreement without the execution or filing of any
paper or any further act on the part of any of the parties hereto. Notice of any
such merger, consolidation or sale shall forthwith be given to the Corporation
and the Trustee.

            5. Any notice required to be given hereunder shall be delivered in

                  Upon the basis of such examination and subject to the
limitations contained herein, it is my opinion that:

                           1. The Company has been duly incorporated and is an
         existing corporation in good standing under the laws of the State of
         Ohio.

                           2. The Indenture has been duly authorized and validly
         executed and delivered by the Company by its duly authorized officers,
         and the issuance and specific terms of the New Junior Subordinated
         Debentures have been duly authorized by all necessary corporate action
         on the part of the Company.

                           3. The New Guarantee Agreement has been duly
         authorized by all necessary corporate action on the part of the
         Company.

                  The foregoing opinion is limited to the federal laws of the
United States and the laws of the State of Ohio, and I am expressing no opinion
as to the effect of the laws of any other jurisdiction.

                  In rendering the foregoing opinion, I have relied to the
extent I deem such reliance appropriate as to certain matters on statements
representations and other information obtained from public officials, officers
of the Company and other sources believed by me to be responsible.

                  I hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the reference to me in the Prospectus that
is a part of the Registration Statement. In giving such consent, I do not
thereby admit that I am in the category of persons whose consent is required
under Section 7 of the Act.

Ladies and Gentlemen:

               This opinion is delivered in connection with the Registration
Statement on Form S-4 (the "Registration Statement") filed under the Securities
Act of 1933, as amended (the "Act"), by Star Banc Corporation, an Ohio
corporation (the "Company"), and Star Capital I, a Delaware statutory business
trust (the "Trust", and together with the Company, the "Registrants"), which
Registration Statement relates to (i) $150,000,000 aggregate liquidation amount
of the Trust's Floating Rate Capital Securities due June 15, 2027 (the "New
Capital Securities"), representing beneficial ownership interests in the Trust,
to be exchanged for $150,000,000 of the Trust's outstanding Floating Rate
Capital Securities due June 15, 2027 (the "Old Capital Securities"), (ii)
$150,000,000 aggregate principal amount of the Company's Floating Rate Junior
Subordinated Debentures (the "New Junior
<PAGE>   2

Subordinated Debentures") to be issued by the Company and exchanged for 
$150,000,000 aggregate principal amount of the Company's outstanding Floating
Rate Junior Subordinated Debentures (the "Old Junior Subordinated Debentures")
and (iii) an unconditional and irrevocable guarantee (the "New Guarantee") of
the obligations of the Trust under the New Capital Securities to be issued by
the Company and exchanged for the Company's outstanding guarantee (the "Old
Guarantee") of the obligations of the Trust under the Old Capital Securities.

               We have examined (i) the Registration Statement, (ii) the Junior
Subordinated Indenture (the "Indenture") between the Company and The First
National Bank of Chicago, as Indenture Trustee (the "Indenture Trustee"), dated
as of June 8, 1997 and filed as an exhibit to the Registration Statement, 
pursuant to which the New Junior Subordinated Debentures are to be issued, and 
(iii) the form of Guarantee Agreement (the "Guarantee Agreement") to be 
executed by the Company and The First National Bank of Chicago, as Guarantee 
Trustee (the "Guarantee Trustee"), relating to the New Guarantee, as filed as 
an exhibit to the Registration Statement. In addition, we have examined, and 
have relied as to matters of fact upon, originals or copies, certified or 
otherwise identified to our satisfaction, of such corporate records, 
agreements, documents and other instruments and such certificates or comparable
documents of public
<PAGE>   3
Star Banc Corporation               -3-

officials and of officers and representatives of the Company, and have made such
other and further investigations, as we have deemed relevant and necessary as a
basis for the opinions hereinafter set forth.

         In such examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies, and the
authenticity of the originals of such latter documents. We have also assumed
that the Registration Statement, and any applicable amendments thereto
(including post-effective amendments), will have become effective under the Act
at the time of issuance of such New Capital Securities, New Junior Subordinated
Debentures and New Guarantee.

         Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that:

                  1. Assuming that the Indenture has been duly authorized,
         executed and delivered by the Company and the Indenture Trustee and 
         that the issuance and specific terms of the New Junior Subordinated
         Debentures have been duly authorized by all necessary corporate action
         on the part of the Company, when such New Junior Subordinated
         Debentures have been duly executed, authenticated, issued and delivered
         in accordance with the provisions of the Indenture upon exchange of the
         Old Junior Subordinated Debentures as contemplated by the Registration
         Statement, such New Junior Subordinated Debentures will constitute
         valid and legally binding obligations of the Company, enforceable
         against the Company in accordance with their terms.
<PAGE>   4
Star Banc Corporation               -4-


                  2. Assuming that the Company has taken all necessary corporate
         action to authorize the issuance of the New Guarantee, when the
         Guarantee Agreement has been duly executed and delivered by the Company
         and the Guarantee Trustee, the New Guarantee will constitute a valid
         and legally binding obligation of the Company, enforceable against the
         Company in accordance with its terms.

               Our opinions set forth in paragraphs 1 and 2 above are subject to
the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, general equitable principles (whether considered in a proceeding in
equity or at law) and an implied covenant of good faith and fair dealing.

               We are members of the Bar of the State of New York and we do not
express any opinion herein concerning any law other than the law of the State of
New York and the federal law of the United States.

               We hereby consent to the filing of this opinion letter as an
exhibit to the Registration Statement and to the reference to us under the
caption "Legal Matters" in the Prospectus forming a part of the Registration
Statement.

Star Capital I
c/o Star Banc Corporation

Cincinnati, Ohio  45202

                  RE:      STAR CAPITAL I

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for Star Banc
Corporation, a Delaware corporation (the "Company"), and Star Capital I, a
Delaware business trust (the "Trust"), in connection with the matters set forth
herein. At your request, this opinion is being furnished to you.

                  For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

                  (a) The Restated Certificate of Trust of the Trust, dated as
of June 8, 1997 (the "Certificate"), as filed in the office of the Secretary of
State of the State of Delaware (the "Secretary of State") on June 10, 1997;

                  (b) The Declaration of Trust of the Trust, dated as of June 5,
1997, among the Company and the trustees of the Trust named therein;
<PAGE>   2
Star Capital I

Page 2


                  (c) The Amended and Restated Declaration of Trust of the
Trust, dated as of June 8, 1997, including Exhibits A and B thereto (the
"Declaration"), among the Company, as sponsor, the trustees of the Trust named
therein, and the holders, from time to time, of undivided beneficial interests
in the assets of the Trust;

                  (d) The Registration Statement on Form S-4 (the "Registration
Statement"), including a preliminary prospectus (the "Prospectus"), relating to
the exchange of up to $150,000,000 aggregate liquidation amount of Floating Rate
Capital Securities of the Trust (each, an "Exchange Capital Security" and
collectively, the "Exchange Capital Securities") for a like liquidation amount
of outstanding Floating Rate Capital Securities of the Trust, as proposed to be
filed by the Company and the Trust with the Securities and Exchange Commission
on or about August 8, 1997; and

                  (e) A Certificate of Good Standing for the Trust, dated August
8, 1997, obtained from the Secretary of State.

                  Initially capitalized terms used herein and not otherwise
defined are used as defined in the Declaration.

                  For purposes of this opinion, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

                  With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Declaration constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Declaration and the
Certificate are in full force and effect and have not been amended, (ii) except
to the extent provided in paragraph 1 below, the due creation or due
organization or due formation, as the case may be, and valid existence in good

standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are parties to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) the due authorization, execution and delivery by all parties
thereto of all documents examined by us, (vi) the receipt by each Person to whom
an Exchange Capital Security is to be issued by the Trust (collectively, the
"Exchange Capital Security Holders") of a certificate evidencing the Exchange
Capital Security and the consideration for the Exchange Capital Security
acquired by it, in accordance with the Declaration, and as described in the
Registration Statement, and (vii) that the Exchange Capital Securities are
issued to the Exchange Capital Security Holders in accordance with the
Declaration, and as described in the Registration Statement. We have not
participated in the preparation of the Registration Statement and assume no
responsibility for its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1. The Trust has been duly created and is validly existing in
good standing as a business trust under the Delaware Business Trust Act, 12 Del.
C. Section 3801, et seq.

                  2. The Exchange Capital Securities will represent valid and,
subject to the qualifications set forth in paragraph 3 below, fully paid and
nonassessable undivided beneficial interests in the assets of the Trust.

                  3. The Exchange Capital Security Holders, as beneficial owners
of the Trust, will 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. We note that the Exchange
Capital Security Holders may be obligated to make payments as set forth in the
Declaration.

upon this opinion in connection with an opinion to be rendered by it as

Ladies and Gentlemen:

               We have acted as special United States federal income tax counsel
("Tax Counsel") to Star Banc Corporation, a bank holding company organized under
the laws of the State of Ohio (the "Company"), and Star Capital I, a statutory
business trust organized under the Business Trust Act of the State of Delaware
(the "Trust"), in connection with the preparation and filing by the Company and
the Trust with the Securities and Exchange Commission (the "Commission") of a
Registration Statement on Form S-4 (as amended, the "Registration Statement")
under the Securities Act of 1933, as amended (the "Securities Act"), registering
the exchange (referred to collectively herein as the "Exchange"), of: (i) up to
$150,000,000 aggregate liquidation amount of Floating Rate Capital Securities
(the "New Capital Securities"), which will

have been registered under the Securities Act pursuant to the Registration
Statement, for a like liquidation amount of the Trust's outstanding Floating
Rate Capital Securities (the "Old Capital Securities"); (ii) the Company's
guarantee (which is set forth in the Guarantee Agreement, dated as of June 8,
1997, between the Company and The First National Bank of Chicago, as trustee
(the "Old Guarantee Trustee")), of the payment of distributions and payments
upon liquidation or redemption of the Trust Securities (the "Old Guarantee") for
a like guarantee (which will be set forth in a new Guarantee Agreement between
the Company and The First National Bank of Chicago, as trustee (the "New
Guarantee Trustee")) of the Trust Securities (the "New Guarantee"), which will
have been registered under the Securities Act pursuant to the Registration
Statement; and (iii) all of the Company's outstanding Floating Rate Junior
Subordinated Debentures (the "Old Junior Subordinated Debentures") for a like
aggregate principal amount of Floating Rate Junior Subordinated Debentures (the
"New Junior Subordinated Debentures"), which will have been registered under the
Securities Act pursuant to the Registration Statement.

               All capitalized terms used in this opinion letter and not
otherwise defined herein shall have the meaning ascribed to such terms in the
Registration Statement.

               In delivering this opinion letter, we have reviewed and relied
upon: (i) the Registration Statement; (ii) the

Indenture, dated as of June 8, 1997 (the "Indenture"), between the Company and
The First National Bank of Chicago, as trustee (the "Indenture Trustee"); (iii)
forms of the Old Junior Subordinated Debentures and the New Junior Subordinated
Debentures; (iv) the Amended and Restated Declaration of Trust, dated as of June
8, 1997 (the "Declaration"), among the Company, as Depositor, The First National
Bank of Chicago, as the initial Property Trustee, First Chicago Delaware Inc.,
as the initial Delaware Trustee and the Regular Trustees named therein; (v) the
Old Guarantee and a form of the New Guarantee; and (vi) forms of the Trust
Securities. Further, we have relied upon certain other statements and
representations contained in the Company's letter of representation dated June
8, 1997. We also have examined and relied upon originals or copies, certified or
otherwise identified to our satisfaction, of such records of the Company and the
Trust and such other documents, certificates and records as we have deemed
necessary or appropriate as a basis for the opinions set forth herein.

               In our examination of such material, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals and the conformity to original documents of all copies of documents
submitted to us. In addition, we also have assumed that (i) the transactions
related to the original issuance of the Old Junior Subordinated Debentures, the
Old Capital Securities and the 
<PAGE>   4
Star Banc Corporation                 -4-                         August 8, 1997



Common Securities were consummated in accordance with the terms of the documents
and forms of documents described herein and (ii) the Exchange will be
consummated in accordance with the terms of such documents and forms of
documents.

               On the basis of the foregoing and assuming that the Trust was
formed and will be maintained in compliance with the terms of the Declaration,
we hereby confirm (i) our opinions set forth in the Registration Statement under
the caption "Certain United States Federal Income Tax Consequences" and (ii)
that, subject to the qualifications set forth therein, the discussion set forth
in the Registration Statement under such caption is an accurate summary of the
United States federal income tax matters described therein.

               We express no opinion with respect to the transactions referred
to herein or in the Registration Statement other than as expressly set forth
herein. Moreover, we note that there is no authority directly on point dealing
with securities such as the Trust Securities or transactions of the type
described herein and that our opinion is not binding on the Internal Revenue
Service or the courts, either of which could take a contrary position.
Nevertheless, we believe that if challenged, the opinions we express herein
would be sustained by a court with jurisdiction in a properly presented case.

               Our opinion is based upon the Code, the Treasury regulations
promulgated thereunder and other relevant authorities and law, all as in effect
on the date hereof. Consequently, future changes in the law may cause the tax
treatment of the transactions referred to herein to be materially different from
that described above.

               We are admitted to practice law only in the State of New York and
the opinions we express herein are limited solely to matters governed by the

thereof), waives any right to receive any notice of the acceptance of such

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 principal amount of Old Capital Securities and any other required

                                                                              13


If less than all the Old Capital Securities evidenced by any Certificate 
submitted are to be tendered, fill in the principal amount of Old Capital 
Securities which are to be tendered in the box entitled "Principal Amount of 
Old Capital Securities Tendered (if less than all)." In such case, new 
Certificate(s) for the remainder of the Old Capital Securities that were 
evidenced by your old Certificate(s) will only be sent to the holder of the Old
Capital Security, promptly after the Expiration Date. 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, telegraphic,
telex or facsimile transmission of such notice of withdrawal must be timely
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 principal 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 in "The Exchange
Offer--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,
telegraphic, telex 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 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 Company and the
Trust, in their sole discretion, whose determination shall be final and binding
on all parties. The Company and the Trust, any affiliates or assigns of the
Company and the Trust, the Exchange Agent or any other person shall not 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 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
<PAGE>   14
                                                                              14


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 or an
Agent's Message in lieu 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 Company and the Trust, in their sole discretion, of
such persons' authority to so act.

        When this Letter of Transmittal is signed by the registered owner(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 owner(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 Company, the Trust or the Trustee for the Old Capital
Securities 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 Company 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 Company and the Trust reserve the absolute right 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 Company
and the Trust, be unlawful. The Company and the Trust also reserve the absolute
right, subject to applicable law, to waive any of the conditions of the Exchange
Offer set
<PAGE>   15
                                                                              15


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 Company'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. The Company, the Trust, any affiliates or assigns of the
Company, the Trust, the Exchange Agent, or any other person shall not be under
any duty to give notification of any irregularities in tenders or incur any
liability for failure to give such notification.

        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, the Notice of Guaranteed Delivery and the
Letter of Transmittal 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 days 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
<PAGE>   16
                                                                              16


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
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.

                          FORM OF EXCHANGE AGENT AGREEMENT



The First National Bank of Chicago
Corporate Trust Trustee Administration
One First National Plaza
Chicago, Illinois 60670

Ladies and Gentlemen:

        Star Capital I, a Delaware statutory business trust (the "Trust"), and
Star Banc Corporation, an Ohio corporation, as Sponsor (the "Company"), propose
to make an offer (the "Exchange Offer") to exchange an aggregate liquidation
amount of the Trust's Floating Rate Capital Securities due June 15, 2027 (the
"Old Capital Securities") for a like aggregate liquidation amount of the
Trust's Floating Rate Capital Securities due June 15, 2027 (the "New Capital
Securities"). The terms and conditions of the Exchange Offer as currently
contemplated are set forth in a prospectus, dated           , 1997 (as the same
may be amended or supplemented from time to time, the "Prospectus"), proposed
to be distributed to all record holders of the Old Capital Securities. The Old
Capital Securities and the New Capital Securities are collectively referred to
herein as the "Capital Securities".

        Each of the Company and the Trust hereby appoints The First National
Bank of Chicago to act as exchange agent (the "Exchange Agent") in connection
with the Exchange Offer. References hereinafter to "you" shall refer to The
First National Bank of Chicago.

        The Exchange Offer is expected to be commenced by the Company and the
Trust on or about            , 1997. The Letter of Transmittal accompanying the
Prospectus (or in the case of book-entry securities the ATOP system) is to be
used by the holders of the Old Capital Securities to accept the Exchange Offer
and contains instructions with respect to the delivery of (i) certificates for
Old Capital Securities tendered in connection therewith and (ii) the book-entry
transfer of Capital Securities to the Exchange Agent's account.

        The Exchange Offer shall expire at 5:00 P.M., New York City time, on
          , 1997 unless the Exchange Offer is extended by the Company (the

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.

the conditions of the Exchange Offer

                                                                               2

specified in the Prospectus under the caption "The Exchange Offer - Conditions
to the Exchange Offer."

        In carrying out your duties as Exchange Agent, you are to act in
accordance with the following instructions:

        1. You will perform such duties and only such duties as are
specifically set forth in the section of the Prospectus captioned "The Exchange
Offer" or as specifically set forth herein; provided, however, that in no way
will your general duty to act in good faith be discharged by the foregoing.

        2. You will establish an account with respect to the Old Capital
Securities at The Depository Trust Company (the "Book-Entry Transfer Facility")
for purposes of the Exchange Offer within two business days after the date of
the Prospectus, and any financial institution that is a participant in the
Book-Entry Transfer Facility's systems may make book-entry delivery of the Old
Capital Securities by causing the Book-Entry Transfer Facility to transfer such
Old Capital Securities into your account in accordance with the Book-Entry
Transfer Facility's procedure for such transfer.

        3. You are to examine each of the Letters of Transmittal and
certificates for Old Capital Securities (or confirmation of book-entry transfer
into your account at the Book-Entry Transfer Facility) and any other documents
delivered or mailed to you by or for holders of the Old Capital Securities to
ascertain whether: (i) the Letters of Transmittal and any such other documents
are duly executed and properly completed in accordance with instructions set
forth therein and (ii) the Old Capital Securities have otherwise been properly
tendered. In each case where the Letter of Transmittal or any other document
has been improperly completed or executed or any of the certificates for Old
Capital Securities are not in proper form for transfer or some other
irregularity in connection with the acceptance of the Exchange Offer exists,
you will endeavor to inform the presenters of the need for fulfillment of all
requirements and to take any other action as may be necessary or advisable to
cause such irregularity to be corrected.

        4. With the prior approval of any Trustee of the Trust (such approval,
if given orally, to be confirmed in writing) or any other party designated by
such Trustee in writing, you are authorized to waive any irregularities in
connection with any tender of Old Capital Securities pursuant to the Exchange
Offer.

        5. Tenders of Old Capital Securities may be made only as set forth in
the Letter of Transmittal and in the section of the Prospectus captioned "The
Exchange Offer - Procedures for Tendering Old Capital Securities'', and Old
Capital Securities shall be considered properly tendered to you only when
tendered in accordance with the procedures set forth therein.

        Notwithstanding the provisions of this paragraph 5, Old Capital
Securities which any Trustee of the Trust shall approve as having been properly
tendered shall be

<PAGE>   3
                                                                               3


considered to be properly tendered (such approval, if given orally, shall be
confirmed in writing).

        6. You shall advise the Trust with respect to any Old Capital Securities
received subsequent to the Expiration Date and accept the Trust's instructions
with respect to disposition of such Old Capital Securities,

        7. You shall accept tenders:

        (a) in cases where the Old Capital Securities are registered in two or
    more names, only if signed by all named holders;

        (b) in cases where the signing person (as indicated on the Letter of
    Transmittal) is acting in a fiduciary or a representative capacity, only
    when proper evidence of his or her authority so to act is submitted; and 

        (c) from persons other than the registered holder of Old Capital
    Securities provided that customary transfer requirements, including any
    applicable transfer taxes, are fulfilled.

        You shall accept partial tenders of Old Capital Securities where so
indicated and as permitted in the Letter of Transmittal and deliver certificates
for Old Capital Securities to the transfer agent for split-up and return any
untendered Old Capital Securities to the holder (or such other person as may be
designated in the Letter of Transmittal) as promptly as practicable after
expiration or termination of the Exchange Offer.

        8. Upon satisfaction or waiver of all of the conditions to the Exchange
Offer, the Trust will notify you (such notice if given orally, to be confirmed
in writing) of its acceptance, promptly after the Expiration Date, of all Old
Capital Securities properly tendered, and you, on behalf of the Trust, will
exchange such Old Capital Securities for New Capital Securities and cause such
Old Capital Securities to be cancelled. Delivery of New Capital Securities will
be made on behalf of the Trust by you at the rate of $1,000 principal amount of
New Capital Securities for each $1,000 principal amount of Old Capital
Securities tendered promptly after notice (such notice if given orally, to be
confirmed in writing) of acceptance of said Old Capital Securities by the Trust;
provided, however, that in all cases, Old Capital Securities tendered pursuant
to the Exchange Offer will be exchanged only after timely receipt by you of
certificates for such Old Capital Securities (or confirmation of book-entry
transfer into your account at the Book-Entry Transfer Facility), a properly
completed and duly executed Letter of Transmittal (or facsimile thereof) with
any required signature guarantees and any other required documents. You shall
issue New Capital Securities only in denominations of $1,000 or any integral
multiple thereof.

        9. Tenders pursuant to the Exchange Offer are irrevocable, except that,
subject to the terms and upon the conditions set forth in the Prospectus and the
Letter of Transmittal, Old Capital Securities tendered pursuant to the Exchange
Offer may be withdrawn at any time prior to the Expiration Date.

                                                                             4
        
        10. The Trust shall not be required to exchange any Old Capital
Securities tendered if any of the conditions set forth in the Exchange Offer
are not met.

        11. If, pursuant to the Exchange Offer, the Trust does not accept for
exchange all or part of the Old Capital Securities tendered because of an
invalid tender, the occurrence of certain other events set forth in the
Prospectus under the caption "The Exchange Offer - Conditions to the Exchange
Offer" or otherwise, you shall as soon as practicable after the expiration or
termination of the Exchange Offer return those certificates for unaccepted Old
Capital Securities (or effect appropriate book-entry transfer), together with
any related required documents and the Letters of Transmittal relating thereto
that are in your possession, to the persons who deposited them.

        12. All certificates for reissued Old Capital Securities, unaccepted
Old Capital Securities or for New Capital Securities shall be forwarded by (a)
first-class certified mail, return receipt requested under a blanket surety
bond protecting you and the Trust from loss or liability arising out of the
non-receipt or non-delivery of such certificates or (b) by registered mail
insured separately for the replacement value of each of such certificates.

        13. You are not authorized to pay or offer to pay any concessions,
commissions or solicitation fees to any broker, dealer, bank or other persons
or to engage or utilize any person to solicit tenders.

        14. As Exchange Agent hereunder you:

        (a) shall have no duties or obligations other than those specifically
    set forth herein or as may be subsequently agreed to in writing by you and
    the Trust;

        (b) will be regarded as making no representations and having no
    responsibilities as to the validity, sufficiency, value or genuineness of
    any of the certificates or the Old Capital Securities represented thereby
    deposited with you pursuant to the Exchange Offer, and will not be required
    to and will make no representation as to the validity, value or genuineness
    of the Exchange Offer;

        (c) shall not be obligated to take any legal action hereunder which
    might in your reasonable judgment involve any expense or liability, unless
    you have been furnished with reasonable indemnity;

        (d) may reasonably rely on and shall be protected in acting in reliance
    upon any certificate, instrument, opinion, notice, letter, telegram or other
    document or security delivered to you and reasonably believed by you in good
    faith to be genuine and to have been signed by the proper party or parties;

        (e) may reasonably act upon any tender, statement, request, comment,
    agreement or other instrument whatsoever not only as to its due execution
    and validity and effectiveness of its provisions, but also as to the truth
    and accuracy of any

<PAGE>   5
                                                                               5

information contained therein, which you shall in good faith believe to be
genuine or to have been signed or represented by a proper person or persons;

     (f) may rely on and shall be protected in acting upon written or oral
instructions from any officer of the Trust;

     (g) may consult with your counsel with respect to any questions relating to
your duties and responsibilities and the advice or opinion of such counsel shall
be full and complete authorization and protection in respect of any action
taken, suffered or omitted to be taken by you hereunder in good faith and in
accordance with the advice or opinion of such counsel; and

     (h) shall not advise any person tendering Old Capital Securities pursuant
to the Exchange Offer as to the wisdom of making such tender or as to the market
value or decline or appreciation in market value of any Old Capital Securities.

     15. You shall take such action as may from time to time be requested by the
Trust or its counsel (and such other action as you may reasonably deem
appropriate) to furnish copies of the Prospectus, Letter of Transmittal and the
Notice of Guaranteed Delivery (as defined in the Prospectus) or such other forms
as may be approved from time to time by the Trust, to all persons requesting
such documents and to accept and comply with telephone requests for information
relating to the Exchange Offer, provided that such information shall relate only
to the procedures for accepting (or withdrawing from) the Exchange Offer. The
Trust will furnish you with copies of such documents at your request. All other
requests for information relating to the Exchange Offer shall be directed to the
Company's Treasury Division, 425 Walnut Street, Cincinnati, Ohio 45203,
telephone number (513) 632-4000.

     16. You shall advise by facsimile transmission or telephone, and promptly
thereafter confirm in writing to the Trust and such person or persons as it may
request, daily (and more frequently during the week immediately preceding the
Expiration Date and if otherwise requested) up to and including the Expiration
Date, as to the number of Old Capital Securities which have been tendered
pursuant to the Exchange Offer and the items received by you pursuant to this
Agreement, separately reporting and giving cumulative totals as to items
properly received and items improperly received. In addition, you will also
inform, and cooperate in making available to, the Trust or any such other
person or persons upon oral request made from time to time prior to the
Expiration Date of such other information as it or he or she reasonably
requests. Such cooperation shall include, without limitation, the granting by
you to the Trust and such person as the Trust may request of access to those
persons on your staff who are responsible for receiving tenders, in order to
ensure that immediately prior to the Expiration Date the Trust shall have
received information in sufficient detail to enable it to decide whether to
extend the Exchange Offer. You shall prepare a final list of all persons whose
tenders were accepted, the aggregate principal amount of Old Capital Securities
tendered, the aggregate principal amount of Old Capital Securities accepted and
deliver said list to the Trust.

                                                                               6

     17. Letters of Transmittal and Notices of Guaranteed Delivery shall be
stamped by you as to the date and the time of receipt thereof and shall be
preserved by you for a period of time at least equal to the period of time you
preserve other records pertaining to the transfer of securities. You shall
dispose of unused Letters of Transmittal and other surplus materials by
returning them to the Trust.

     18. You hereby expressly waive any lien, encumbrance or right of set-off
whatsoever that you may have with respect to funds deposited with you for the
payment of transfer taxes by reasons of amounts, if any, borrowed by the Trust,
the Company or any  of its subsidiaries or affiliates pursuant to any loan or
credit agreement with you or for compensation owed to you hereunder.

     19. For services rendered as Exchange Agent hereunder, you shall be
entitled to such compensation as set forth on Schedule I attached hereto.

     20. You hereby acknowledge receipt of the Prospectus and the Letter of
Transmittal and further acknowledge that you have examined each of them. Any
inconsistency between this Agreement, on the one hand, and the Prospectus and
the Letter of Transmittal (as they may be amended from time to time), on the
other hand, shall be resolved in favor of the latter two documents, except with
respect to the duties, liabilities and indemnification of you as Exchange Agent,
which shall be controlled by this Agreement.

     21. The Company covenants and agrees to indemnify and hold you harmless in
your capacity as Exchange Agent hereunder against any loss, liability, cost or
expense, including reasonable attorneys' fees and expenses, arising out of or in
connection with any act, omission, delay or refusal  made by you in reliance
upon any signature, endorsement, assignment, certificate, order, request,
notice, instruction or other instrument or document reasonably believed by you
in good faith to be valid, genuine and sufficient and in accepting any tender or
effecting any transfer of Old Capital Securities reasonably believed by you in
good faith to be authorized, and in delaying or refusing in good faith to accept
any tenders or effect any transfer of Old Capital Securities; provided, however,
that the Company shall not be liable for indemnification or otherwise for any
loss, liability, cost or expense to the extent arising out of your gross
negligence or willful misconduct. In no case shall the Company be liable under
this indemnity with respect to any claim against you unless the Company shall be
notified by you, by letter or by facsimile confirmed by letter, of the written
assertion of a claim against you or of any other action commenced against you,
promptly after you shall have received any such written assertion or notice of
commencement of action. The Company shall be entitled to participate at its own
expense in the defense of any such claim or other action, and, if the Company so
elects, the Company shall assume the defense of any suit brought to enforce any
such claim. In the event that the Company shall assume the defense of any such
suit, the Company shall not be liable for the fees and expenses of any
additional counsel thereafter retained by you so long as the Company shall
retain counsel satisfactory to you to defend such suit.

provided, however, that you shall reimburse the Company for amounts refunded to
you in respect of your payment of any such transfer taxes, at such time as such
refund is received by you.
