                          LOAN AND SECURITY AGREEMENT

         This AMENDMENT NUMBER FOUR AND WAIVER AND CONSENT TO LOAN AND SECURITY
AGREEMENT (this "Amendment, Consent and Waiver") is entered into as of October
24, 2000, among DEVX ENERGY, INC., formerly known as Queen Sand Resources,
Inc., a corporation formed under the laws of the State of Delaware ("DEVX");
DEVX ENERGY, INC., formerly known as Queen Sand Resources, Inc., a corporation
formed under the laws of the State of Nevada (the "Borrower"); each of the
lenders that is a signatory hereto (individually, a "Lender" and, collectively,
the "Lenders"); FOOTHILL CAPITAL CORPORATION, as administrative agent for the
Lenders (in such capacity, the "Administrative Agent"); and ABLECO FINANCE LLC,
as collateral agent for the Lenders (in such capacity, the "Collateral Agent"),
with reference to the following facts:

         A.       DEVX, Borrower, the Lenders signatory thereto, Administrative
                  Agent and Collateral Agent, heretofore have entered into that
                  certain Amended and Restated Credit Agreement, dated as of
                  October 22, 1999, as amended by that certain Amendment Number
                  One to Loan and Security Agreement dated as of May 23, 2000,
                  as further amended by that certain Amendment Number Two to
                  Loan and Security Agreement dated as of June 21, 2000, and as
                  further amended by that certain Amendment Number Three to
                  Amended and Restated Credit Agreement dated as of September
                  19, 2000 (as heretofore amended, supplemented, or otherwise
                  modified, the "Agreement");

         B.       DEVX has entered into the Recapitalization Agreement (as
                  defined herein) with the holders of DEVX's Series A preferred
                  stock, Series C preferred stock and common stock repricing
                  rights in which these holders have agreed to exchange all
                  their current holdings of DEVX equity for 732,500 shares of
                  DEVX common stock after giving effect to a 156 to 1 reverse
                  split (the "Share Exchange"). The Recapitalization Agreement
                  is subject to, among other things, (i) DEVX completing an
                  Equity Offering generating net proceeds to DEVX of not less
                  than $50 million on or before October 31, 2000 and (ii) DEVX
                  repurchasing at least $75 million of original principal
                  amount of its Senior Notes. DEVX intends to use a portion of
                  the proceeds of the Equity Offering to finance the repurchase
                  of the Senior Notes.

         C.       The Share Exchange and Equity Offering contemplated by the
                  Recapitalization Agreement may, upon implementation, each
                  constitute a Change of Control as defined under Article I,
                  Section 1.02 of the Agreement. Article IX, Section 9.21 of
                  the Agreement prohibits the repayment of the principal
                  portion of the Senior Notes.

         D.       Accordingly, DEVX and the Borrower have requested that the
                  Lenders (i) waive any non-compliance with the terms and
                  provisions of the Agreement as a result of the repurchase of
                  the Senior Notes from the proceeds of the Equity Offering and
                  the implementation of the Share Exchange as contemplated by
                  the Recapitalization Agreement, (ii) amend the definition in
                  the Agreement of the term Change of Control to permit
                  implementation of the Share Exchange and the Equity Offering
                  as contemplated by the Recapitalization Agreement without
                  triggering

                  a default under the Agreement, (iii) acknowledge and agree
                  that the amounts received by DEVX under the Equity Offering
                  contemplated by the Recapitalization Agreement will be
                  applied first to the repurchase of the Senior Notes and
                  second to the prepayment of any of the Loans or other amounts
                  payable under the Agreement (provided that (i) no reduction
                  in the Aggregate Commitments shall result solely from any of
                  the foregoing events and transactions, and (ii) any such
                  prepayment of Loans may be reborrowed during the Revolving
                  Credit Period subject to the then effective Aggregate
                  Commitments in accordance with Section 2.07(d) of the
                  Agreement), and (iv) waive any non-compliance with the terms
                  of the Loan Documents as a result of certain corporate name
                  changes of the Obligors as more particularly described
                  herein.

         E.       The Lenders are willing to consent to such requests subject
                  to the terms and conditions set forth herein.

                  NOW, THEREFORE, in consideration of the above recitals and
the mutual premises contained herein, the Lenders signatory hereto, the

                  All capitalized terms used herein but not otherwise defined
herein shall have the meanings ascribed to them in that certain Amendment
Number Four and Consent and Waiver to Credit Agreement, dated as of October 24,
2000 (the "Amendment, Consent and Waiver"). Each of the undersigned hereby (a)
represents and warrants to the Agents and the Lenders that the execution,
delivery, and performance of this Reaffirmation and Consent are within its
corporate powers, have been duly authorized by all necessary corporate action,
and are not in contravention of any law, rule, or regulation, or any order,
judgment, decree, writ, injunction, or award of any arbitrator, court, or
governmental authority, or of the terms of its charter or bylaws, or of any
contract or undertaking to which it is a party or by which any of its
properties may be bound or affected; (b) consents to the transactions
contemplated by the Recapitalization Agreement and the amendment of the
Agreement by the Amendment, Consent and Waiver; (c) acknowledges and reaffirms
its obligations owing to the Agents and the Lenders under its respective Second
Amended and Restated Guaranty Agreement dated as of October 22, 1999 (each a
"Guaranty", and collectively, the "Guaranties") and any other Loan Documents to
which it is party; and (d) agrees that the Guaranty and any other Loan
Documents to which it is a party are and shall remain in full force and effect.
Although each of the undersigned has been informed of the matters set forth
herein and has acknowledged and agreed to same, it understands that the Agents
and the Lenders have no obligation to inform it of such matters in the future
or to seek its acknowledgement or agreement to future amendments, and nothing
herein shall create such a duty. This Reaffirmation and Consent may be executed
in any number of counterparts and by different parties on separate
counterparts, each of which, when executed and delivered, shall be deemed to be
an original, and all of which, when taken together, shall constitute but one
and the same Reaffirmation and Consent. Delivery of an executed counterpart of
this Reaffirmation and Consent by telefacsimile shall be equally as effective
as delivery of an original executed counterpart of this Reaffirmation and
Consent. Any party delivering an executed counterpart of this Reaffirmation and
Consent by telefacsimile also shall deliver an original executed counterpart of
this Reaffirmation and Consent but the failure to deliver an original executed
counterpart shall not affect the validity, enforceability, and binding effect
of this Reaffirmation and Consent. This Reaffirmation and Consent shall be
governed by internal laws of the State of New York as more fully set forth in
Section 5.04 of the Guaranties.

         bearer form, registrable or not registrable as to principal, and with
         or without interest coupons;

               (22) if the amount of payments of principal of, any premium and
         interest on and any Additional Amounts with respect to the Debentures
         of the series may be determined with reference to any commodities,
         currencies or indices, values, rates or prices or any other index or
         formula, the manner in which such amounts shall be determined;

               (23) the appointment of any paying agent or agents for the

<PAGE>   18

               (24) the relative degree, if any, to which the Debentures of such
         series shall be senior to or be subordinated to other series of
         Debentures in right of payment, whether such other series of Debentures
         are Outstanding or not; and

               (25) any and all other terms with respect to the Debentures of
         such series (and any terms which may be required by or advisable under
         applicable laws or regulations not inconsistent with the terms of this
         Indenture).

               All Debentures of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to any such Board Resolution or in any indenture supplemental hereto.

               If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action,
together with such Board Resolution, shall be set forth in an Officers'
Certificate or certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth the terms of the series.

               The Debentures shall be subordinated in right of payment to
Senior Debt as provided in Article XIV.

         SECTION 2.02 Form of Debenture and Trustee's Certificate.

               The Debentures of any series and the Certificate of
Authentication to be borne by such Debentures shall be substantially of the
tenor and purport as set forth in one or more indentures supplemental hereto or
as provided in or pursuant to a Board Resolution and as set forth in an
Officers' Certificate, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements typewritten,
printed, lithographed or engraved thereon as the Company may deem appropriate
and as are not inconsistent with the provisions of this Indenture, or as may be
required to comply with any law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange or automated
quotation system on which Debentures of that series may be listed or traded, or
to conform to usage.

         SECTION 2.03  Date and Denominations of Debentures and Provisions for
                       Payment of Principal, Premium and Interest.

               The Debentures shall be issuable as registered Debentures and in
the denominations of $25 or any integral multiple thereof, subject to Section
2.01. The Debentures of a particular series shall bear interest payable on the
dates and at the rate specified with respect to that series. The principal of,
interest on and any Additional Amounts with respect to the Debentures of any
series, as well as any premium thereon in case of redemption thereof prior to
maturity, shall, subject to Section 2.01, be payable in Dollars at a Place of
Payment. The Company may, however, pay such amounts by check payable in such
money mailed to a holder's registered address or by wire transfer of immediately
available funds to an account designated by such holder. Each Debenture shall be
dated the date of its authentication. Interest on the Debentures shall be
computed on the basis of a 360-day year composed of twelve 30-day months,
subject to Section 2.01.

                                       11
<PAGE>   19

               Unless otherwise provided with respect to Debentures of a series
as contemplated by Section 2.01, the interest installment on any Debenture which
is payable, and is punctually paid or duly provided for, on any Interest Payment
Date for Debentures of that series shall be paid to the Person in whose name
said Debenture (or one or more Predecessor Debentures) is registered at the
close of business on the regular record date for such interest installment.
Unless otherwise provided with respect to Debentures of a series as contemplated
by Section 2.01, in the event that any Debenture of such series or portion
thereof is called for redemption and the redemption date is subsequent to a
regular record date with respect to any Interest Payment Date and prior to such
Interest Payment Date, interest on such Debenture will be paid upon presentation
and surrender of such Debenture as provided in Section 3.03.

               Any interest on any Debenture which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date for
Debentures of the same series (herein called "Defaulted Interest") shall
forthwith cease to be payable to the registered holder on the relevant regular
record date by virtue of having been such holder; and such Defaulted Interest
shall be paid by the Company, at its election, as provided in clause (1) or
clause (2) below:

               (1) The Company may make payment of any Defaulted Interest on
         Debentures to the Persons in whose names such Debentures (or their
         respective Predecessor Debentures) 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 such Debenture and the date of the proposed
         payment, and at the same time the Company shall deposit with the
         Trustee an amount of money equal to the aggregate amount proposed to be
         paid in respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         clause provided. Thereupon the Trustee shall fix a special record date
         for the payment of such Defaulted Interest which shall not be more than
         15 nor less than 10 days prior to the date of the proposed payment and
         not less than 10 days after the receipt by the Trustee of the notice of
         the proposed payment. The Trustee shall promptly notify the 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 Debentureholder at his or her address as it
         appears in the Debenture Register, not less than 10 days prior to such
         special record date. Notice of the proposed payment of such Defaulted
         Interest and the special record date therefor having been mailed as
         aforesaid, such Defaulted Interest shall be paid to the Persons in
         whose names such Debentures (or their Predecessor Debentures) are
         registered on such special record date and shall be no longer payable
         pursuant to the following clause (2).

               (2) The Company may make payment of any Defaulted Interest on any
         Debentures in any other lawful manner not inconsistent with the
         requirements of any securities exchange or automated quotation system
         on which such Debentures may be listed or traded, and upon such notice
         as may be required by such exchange or quotation system, if, after
         notice given by the Company to the Trustee of the proposed payment

                                       12
<PAGE>   20

         pursuant to this clause, such manner of payment shall be deemed
         practicable by the Trustee.

               Unless otherwise set forth in or pursuant to a Board Resolution
or in one or more indentures supplemental hereto establishing the terms of any
series of Debentures pursuant to Section 2.01 hereof, the term "regular record
date" as used in this Section with respect to a series of Debentures with
respect to any Interest Payment Date for such series shall mean either the
fifteenth day of the month immediately preceding the month in which an Interest
Payment Date established for such series pursuant to Section 2.01 hereof shall
occur, if such Interest Payment Date is the first day of a month, or the last
day of the month immediately preceding the month in which an Interest Payment
Date established for such series pursuant to Section 2.01 hereof shall occur, if
such Interest Payment Date is the fifteenth day of a month, whether or not such
date is a Business Day.

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

         SECTION 2.04 Execution of Debentures.

               The Debentures shall, subject to the provisions of Section 2.06,
be printed on steel engraved borders or fully or partially engraved, or legibly
typed, as determined by the Officers of the Company executing such Debentures,
and shall be signed on behalf of the Company by two Officers of the Company.
Each such signature may be in the form of a manual or facsimile signature and
may be imprinted or otherwise reproduced on the Debentures and for that purpose
the Company may use the manual or facsimile signature of any individual who
shall have been an Officer of the Company, notwithstanding the fact that at the
time the Debentures shall be authenticated and delivered or disposed of such
individual shall have ceased to be such an Officer.

               Only such Debentures as shall bear thereon a Certificate of
Authentication substantially in the form established for such Debentures,
executed manually by an authorized signatory of the Trustee, or by any
Authenticating Agent with respect to such Debentures, shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such
certificate executed by the Trustee, or by any Authenticating Agent appointed by
the Trustee with respect to such Debentures, upon any Debenture executed by the
Company shall be conclusive evidence that the Debenture so authenticated has
been duly authenticated and made available for delivery hereunder and that the
holder is entitled to the benefits of this Indenture. Notwithstanding the
foregoing, if any Debenture shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Debenture to the Trustee for cancellation as provided in Section
2.08, for all purposes of this Indenture such Debenture shall be deemed never to
have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture.

               At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Debentures of any series
executed by the Company to the

                                       13
<PAGE>   21

Trustee for authentication, together with a written order of the Company for the
authentication and delivery of such Debentures, signed by two Officers of the
Company, and the Trustee in accordance with such written order shall
authenticate and make available for delivery such Debentures. Each Debenture
shall be dated the date of its authentication by the Trustee.

               In authenticating such Debentures and accepting the additional
responsibilities under this Indenture in relation to such Debentures, the
Trustee shall be entitled to receive, and (subject to Section 7.01) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been established in conformity with the provisions of this
Indenture.

               The Trustee shall not be required to authenticate such Debentures
if the issue of such Debentures pursuant to this Indenture will affect the
Trustee's own rights, duties or immunities under the Debentures and this
Indenture or otherwise in a manner which is not reasonably acceptable to the
Trustee.

         SECTION 2.05 Exchange of Debentures.

               (a) Debentures of any series may be exchanged upon presentation
thereof at a Place of Payment, for other Debentures of such series of authorized
denominations, and for a like aggregate principal amount, upon payment of a sum
sufficient to cover any tax or other governmental charge in relation thereto,
all as provided in this Section. In respect of any Debentures so surrendered for
exchange, the Company shall execute, the Trustee shall authenticate and such
office or agency shall make available for delivery in exchange therefor the
Debenture or Debentures of the same series which the Debentureholder making the
exchange shall be entitled to receive, bearing numbers not contemporaneously
outstanding.

               (b) The Company shall keep, or cause to be kept, at an office or
agency in each Place of Payment (the register maintained in any such office or
agency of the Company is herein sometimes collectively referred to as the
"Debenture Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall register the Debentures and the transfers and
exchanges of Debentures as provided in this Article and which at all reasonable
times shall be open for inspection by the Trustee. The registrar for the purpose
of registering Debentures and transfer and exchange of Debentures as provided
herein shall be appointed by the Company (the "Debenture Registrar"). The
initial Debenture Registrar shall be the Trustee.

               Upon surrender for transfer or exchange of any Debenture at the
office or agency of the Company in a Place of Payment, the Company shall execute
and the Trustee shall authenticate and deliver, in the name of the transferee or
transferees, one or more new Debentures of the same series as the Debenture
presented, of any authorized denominations and of like tenor and aggregate
principal amount.

               All Debentures presented or surrendered for exchange or
registration of transfer, as provided in this Section, shall be duly endorsed or
accompanied (if so required by the Company or the Debenture Registrar) by a
written instrument or instruments of transfer, in form satisfactory to the
Company or the Debenture Registrar, duly executed by the registered holder or by
his duly authorized attorney in writing.

                                       14
<PAGE>   22

               (c) No service charge shall be made for any exchange or
registration of transfer of Debentures, or issue of new Debentures in case of
partial redemption of any series, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge in relation thereto,
other than exchanges pursuant to Section 2.06, Section 3.03(b) and Section 9.04
not involving any transfer.

               (d) Notwithstanding any other provisions of this Indenture to the
contrary, the Company shall not be required (i) to issue, exchange or register
the transfer of any Debentures during a period beginning 15 Business Days before
the day of the mailing of a notice of redemption of less than all the
outstanding Debentures of the same series and ending at the close of business on
the day of such mailing or (ii) to register the transfer of or exchange any
Debentures of any series or portions thereof called for redemption, except the
unredeemed portion of any Debenture being redeemed in part.

               (e) The provisions of this Section 2.05 are, with respect to any
Global Debenture, subject to Section 2.11 hereof.

         SECTION 2.06 Temporary Debentures.

               Pending the preparation of definitive Debentures of any series,
the Company may execute, and the Trustee shall authenticate and make available
for delivery, temporary Debentures (printed, lithographed or typewritten) of any
authorized denomination, and substantially in the form of the definitive
Debentures in lieu of which they are issued, but with such omissions, insertions
and variations as may be appropriate for temporary Debentures, all as may be
determined by the Company. Every temporary Debenture of any series shall be
executed by the Company and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the
definitive Debentures of such series. Without unnecessary delay the Company will
execute and will furnish definitive Debentures of such series and thereupon any
or all temporary Debentures of such series may be surrendered in exchange
therefor (without charge to the holders), at a Place of Payment, and upon
receipt of a written order of the Company signed by two Officers of the Company,
the Trustee shall authenticate and deliver in exchange for such temporary
Debentures an equal aggregate principal amount of definitive Debentures of such
series, unless the Company advises the Trustee to the effect that definitive
Debentures need not be executed and furnished until further notice from the
Company. Until so exchanged, the temporary Debentures of such series shall be
entitled to the same benefits under this Indenture as definitive Debentures of
such series authenticated and delivered hereunder.

         SECTION 2.07 Mutilated, Destroyed, Lost or Stolen Debentures.

               In case any temporary or definitive Debenture shall become
mutilated or be destroyed, lost or stolen, the Company (subject to the next
succeeding sentence) shall execute, and upon its written request the Trustee
(subject as aforesaid) shall authenticate and make available for delivery, a new
Debenture of the same series bearing a number not contemporaneously outstanding,
in exchange and substitution for the mutilated Debenture, or in lieu of and in
substitution for the Debenture so destroyed, lost or stolen. In every case the
applicant for a substituted Debenture shall furnish to the Company and to the
Trustee such

                                       15
<PAGE>   23

security or indemnity as may be required by them to save each of them harmless,
and, in every case of destruction, loss or theft, the applicant shall also
furnish to the Company and to the Trustee evidence to their satisfaction of the
destruction, loss or theft of the applicant's Debenture and of the ownership
thereof. The Trustee may authenticate any such substituted Debenture and make
available for delivery the same upon the written request or authorization of any
Officer of the Company. Upon the issuance of any substituted Debenture, 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.
In case any Debenture which has matured or is about to mature shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Debenture, pay or authorize the payment of the same (without
surrender thereof except in the case of a mutilated Debenture) if the applicant
for such payment shall furnish to the Company and to the Trustee such security
or indemnity as they may require to save them harmless, and, in case of
destruction, loss or theft, evidence to the satisfaction of the Company and the
Trustee of the destruction, loss or theft of such Debenture and of the ownership
thereof.

               Every Debenture issued pursuant to the provisions of this Section
in substitution for any Debenture which is mutilated, destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the mutilated, destroyed, lost or stolen Debenture shall be found at any
time, or be enforceable by anyone, and shall be entitled to all the benefits of
this Indenture equally and proportionately with any and all other Debentures of
the same series duly issued hereunder. All Debentures shall be held and owned
upon the express condition that the foregoing provisions are exclusive with
respect to the replacement or payment of mutilated, destroyed, lost or stolen
Debentures, and shall preclude (to the extent lawful) any and all other rights
or remedies, notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

               SECTION 2.08  Cancellation of Surrendered Debentures.

               All Debentures surrendered for the purpose of payment,
redemption, exchange or registration of transfer shall, if surrendered to the
Company, any Debenture Registrar or any paying agent, be delivered to the
Trustee for cancellation, or, if surrendered to the Trustee, shall be cancelled
by it, and no Debentures shall be issued in lieu thereof except as expressly
required or permitted by any of the provisions of this Indenture. On written
request of the Company, the Trustee shall deliver to the Company cancelled
Debentures held by the Trustee. If the Company shall otherwise acquire any of
the Debentures, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Debentures unless and until
the same are delivered to the Trustee for cancellation.

               SECTION 2.09  Provisions of Indenture and Debentures for
                             Sole Benefit of Parties and Debentureholders.

               Except as provided in Article XIV with respect to the holders of
Senior Debt and except as provided in Sections 6.01(e) and 13.12, nothing in
this Indenture or in the Debentures, express or implied, shall give or be
construed to give to any Person, other than the parties hereto and the holders
of the Debentures, any legal or equitable right, remedy or claim under or in

                                       16
<PAGE>   24

respect of this Indenture, or under any covenant, condition or provision herein
contained; all such covenants, conditions and provisions being (except as so
provided) for the sole benefit of the parties hereto and of the holders of the
Debentures.

         SECTION 2.10 Appointment of Authenticating Agent.

               So long as any of the Debentures of any series remain outstanding
there may be an Authenticating Agent for any or all such series of Debentures
which the Trustee shall have the right to appoint. Said Authenticating Agent
shall be authorized to act on behalf of the Trustee to authenticate Debentures
of such series issued upon exchange, transfer or partial redemption thereof, and
Debentures so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. All references in this Indenture to the authentication of
Debentures by the Trustee shall be deemed to include authentication by an
Authenticating Agent for such series. Each Authenticating Agent shall be
acceptable to the Company and shall be a corporation which has a combined
capital and surplus, as most recently reported or determined by it, sufficient
under the laws of any jurisdiction under which it is organized or in which it is
doing business to conduct a trust business, and which is otherwise authorized
under such laws to conduct such business and is subject to supervision or
examination by Federal or State authorities. If at any time any Authenticating
Agent shall cease to be eligible in accordance with these provisions, it shall
resign immediately.

               Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time (and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint an
eligible successor Authenticating Agent acceptable to the Company. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto.

         SECTION 2.11 Global Debentures.

               (a) If the Company shall establish pursuant to Section 2.01 that
the Debentures of a particular series are to be issued as one or more Global
Debentures, then the Company shall execute and the Trustee shall, in accordance
with Section 2.04, authenticate and deliver, one or more Global Debentures which
shall represent such of the outstanding Debentures of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of outstanding Debentures from time to time endorsed thereon and that the
aggregate amount of outstanding Debentures represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges or
redemptions. Any endorsement of a Global Debenture to reflect the amount, or any
increase or decrease in the amount, of outstanding Debentures represented
thereby shall be made by the Trustee (i) in such manner and upon instructions
given by such Person or Persons as shall be specified in such Debenture or in a
written order of the Company to be delivered to the Trustee pursuant to Section
2.04 or (ii) otherwise in accordance with written instructions or such other
written form of instructions as is

                                       17
<PAGE>   25

customary for the Depositary for such Debenture, from such Depositary or its
nominee on behalf of any Person having a beneficial interest in such Global
Debenture. Subject to the provisions of Section 2.04 and, if applicable, Section
2.06, the Trustee shall deliver and redeliver any Debenture in permanent global
form in the manner and upon instructions given by the Person or Persons
specified in such Debenture or in the applicable written order of the Company.
With respect to the Debentures of any series that are represented by a Global
Debenture, the Company authorizes the execution and delivery by the Trustee of a
letter of representations or other similar agreement or instrument in the form
customarily provided for by the Depositary appointed with respect to such Global
Debenture. Any Global Debenture may be deposited with the Depositary or its
nominee, or may remain in the custody of the Trustee or the Debenture Custodian
therefor pursuant to a FAST Balance Certificate Agreement or similar agreement
between the Trustee and the Depositary. If a written order of the Company has
been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Debenture in global form
shall be in writing but need not comply with Section 13.06 and need not be
accompanied by an Opinion of Counsel.

               (b) Notwithstanding the provisions of Section 2.05, the Global
Debenture of a series may be transferred, in whole but not in part and in the
manner provided in Section 2.05, only to another nominee of the Depositary for
such series, or to a successor Depositary for such series selected or approved
by the Company or to a nominee of such successor Depositary.

               (c) If either (i) at any time the Depositary for a series of
Debentures notifies the Company that it is unwilling or unable to continue as
Depositary for such series or if at any time the Depositary for such series
shall no longer be registered or in good standing under the Exchange Act or
other applicable statute or regulation and a successor Depositary for such
series is not appointed by the Company within 90 days after the Company receives
such notice or becomes aware of such condition, as the case may be, or (ii) an
Event of Default has occurred with respect to a series of Debentures and is
continuing and the Debenture Registrar has received a request from the
Depositary to issue Debentures of such series in lieu of all or a portion of
that Global Debenture (in which case the Company shall deliver Debentures of
such series within 30 days of such request), this Section 2.11 shall no longer
be applicable to the Debentures of such series and the Company will execute, and
subject to Section 2.05, the Trustee will authenticate and make available for
delivery Debentures of such series in definitive registered form without
coupons, in authorized denominations, and in an aggregate principal amount equal
to the principal amount of the Global Debentures of such series in exchange for
such Global Debentures. In addition, the Company may at any time determine that
the Debentures of any series shall no longer be represented by one or more
Global Debentures and that the provisions of this Section 2.11 shall no longer
apply to the Debentures of such series. In such event the Company will execute
and subject to Section 2.05, the Trustee, upon receipt of an Officers'
Certificate evidencing such determination by the Company, will authenticate and
deliver Debentures of such series in definitive registered form without coupons,
in authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Debentures of such series in exchange for such
Global Debentures. Upon the exchange of the Global Debentures for such
Debentures in definitive registered form without coupons, in authorized
denominations, the Global Debentures shall be cancelled by the Trustee. Such
Debentures in definitive registered form issued in exchange for the Global
Debentures pursuant to this Section 2.11(c) shall be registered in such names
and in such authorized denominations as

                                       18
<PAGE>   26

the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Debentures to the Depositary for delivery to the Persons in whose name such
Debentures are so registered.

               (d) Unless otherwise provided with respect to Debentures of a
series as contemplated by Section 2.01, Debentures of such series in
certificated form may be presented to the Trustee by the Property Trustee of the
applicable Trust in exchange for one or more Global Debentures registered in the
name of the Depositary or its nominee, and may be deposited with the Depositary
or its nominee, or may remain in the custody of the Trustee or a security
custodian therefor pursuant to a FAST Balance Certificate Agreement or similar
agreement between the Trustee and the Depositary, for credit by the Depositary
to the respective accounts of the beneficial owners of the Debentures
represented thereby (or such other accounts as they may direct). Prior to such
exchange, the Company shall designate the Depositary in writing to the Trustee.

               (e) The Depositary or its nominee, as the registered owner of a
Global Debenture, shall be the holder of such Global Debenture for all purposes
under this Indenture and the Debentures, and owners of beneficial interests in a
Global Debenture shall hold such interests pursuant to the applicable procedures
of the Depositary. Accordingly, any such owner's beneficial interest in a Global
Debenture shall be shown only on, and the transfer of such interest shall be
effected only through, records maintained by the Depositary or its nominee or
its participants. None of the Company, the Trustee or the Debenture Registrar
will have any responsibility or liability for any aspect of the records relating
to, or payments made on account of, Debentures of any series by the Depositary,
or for maintaining, supervising or reviewing any records of the Depositary
relating to such Debentures. None of the Company, the Trustee or the Debenture
Registrar shall be liable for any delay by the Depositary or its nominee or its
participants in identifying the beneficial owners, and each such Person may
conclusively rely on, and shall be protected in relying on, instructions from
the Depositary or such nominee or participants for all purposes (including with
respect to the registration and delivery, and the respective principal amounts,
of the Debentures to be issued).

               (f) The rights of owners of beneficial interests in a Global
Debenture shall be exercised only through the Depositary and shall be limited to
those established by law and agreements between such owners and the Depositary
and/or its participants.

         SECTION 2.12 CUSIP Numbers.

               The Company in issuing the Debentures may use "CUSIP" numbers,
and the Trustee shall use such CUSIP numbers in notices of redemption or
exchange as a convenience to Debentureholders and no representation shall be
made as to the correctness of such numbers either as printed on the Debentures
or as contained in any notice of redemption or exchange.

                                  ARTICLE III

              REDEMPTION OF DEBENTURES AND SINKING FUND PROVISIONS

         SECTION 3.01 Redemption.

               The Company may redeem the Debentures of any series issued
hereunder on and after the dates and in accordance with the terms established
for such series pursuant to Section 2.01 hereof.

         SECTION 3.02 Notice of Redemption.

               (a) In case the Company shall desire to exercise such right to
redeem all or, as the case may be, a portion of the Debentures of any series in
accordance with the right reserved so to do, it shall give notice of such
redemption to the Trustee at least 45 days in advance of the date fixed for
redemption. The Trustee shall then notify holders of the Debentures of such
series who are to be redeemed by mailing, first class postage prepaid, by a
notice of such redemption not less than 30 days and not more than 60 days before
the date fixed for redemption of that series to such holders at their last
addresses as they shall appear upon the Debenture Register. Any notice which is
mailed in the manner herein provided shall be conclusively presumed to have been
duly given, whether or not the registered holder receives the notice. In any
case, failure duly to give such notice to the holder of any Debenture of any
series designated for redemption in whole or in part, or any defect in the
notice, shall not affect the validity of the proceedings for the redemption of
any other Debentures of such series or any other series. In the case of any
redemption of Debentures prior to the expiration of any restriction on such
redemption provided in the terms of such Debentures or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with any such restriction.

               Each such notice of redemption shall identify the Debentures to
be redeemed (including CUSIP number) and shall specify: (a) the date fixed for
redemption, (b) the redemption price at which Debentures of that series are to
be redeemed, (c) the place or places where Debentures are to be surrendered for
payment of the redemption price, (d) that payment of the redemption price will
be made upon presentation and surrender of such Debentures at such place or
places, (e) that interest accrued to the date fixed for redemption will be paid
as specified in said notice, (f) that from and after said date interest will
cease to accrue and (g) that the redemption is for a sinking fund, if such is
the case. If less than all the Debentures of a series are to be redeemed, the
notice to the holders of Debentures of that series to be redeemed in whole or in
part shall specify the particular Debentures to be so redeemed. In case any
Debenture is to be redeemed in part only, the notice which relates to such
Debenture shall state the portion of the principal amount thereof to be
redeemed, and shall state that on and after the redemption date, upon surrender
of such Debenture, a new Debenture or Debentures of such series in principal
amount equal to the unredeemed portion thereof will be issued.

               (b) In the event of a partial redemption of a series of
Debentures, the Company shall give the Trustee at least 45 days' notice in
advance of the date fixed for redemption as to the aggregate principal amount of
Debentures of the series to be redeemed and

                                       20
<PAGE>   28

the other information set forth in the immediately preceding paragraph, and
thereupon the Trustee shall select, pro rata, by lot or in such other manner as
it shall deem appropriate and fair in its discretion and which may provide for
the selection of a portion or portions (equal to $25 or any integral multiple
thereof) of the principal amount of such Debentures of a denomination larger
than $25, the Debentures to be redeemed and shall thereafter promptly notify the
Company in writing of the numbers of the Debentures to be redeemed, in whole or
in part. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Debentures shall relate,
in the case of any Debenture redeemed or to be redeemed only in part, to the
portion of the principal amount of such Debenture which has been or is to be
redeemed. If the Company shall so direct, Debentures registered in the name of
the Company, any Affiliate or any Subsidiary thereof shall not be included in
the Debentures selected for redemption.

               (c) The Company may, if and whenever it shall so elect during any
period in which Debentures of a particular series are subject to redemption, by
delivery of instructions signed on its behalf by an Officer of the Company,
instruct the Trustee or any paying agent to call all or any part of such
Debentures for redemption and to give notice of redemption in the manner set
forth in this Section, such notice to be in the name of the Company or its own
name as the Trustee or such paying agent may deem advisable. In any case in
which notice of redemption is to be given by the Trustee or any such paying
agent, the Company shall deliver or cause to be delivered to, or permit to
remain with, the Trustee or such paying agent, as the case may be, such
Debenture Register, transfer books or other records, or suitable copies or
extracts therefrom, sufficient to enable the Trustee or such paying agent to
give any notice by mail that may be required under the provisions of this
Section.

         SECTION 3.03 Payment Upon Redemption.

               (a) On or prior to any date fixed for redemption, the Company
shall deposit with the Trustee or any paying agent (or, if the Company is acting
as its own paying agent, segregate and hold in trust as provided in Section
4.03) an amount of money in same day funds sufficient to pay the redemption
price of, and accrued interest on and any Additional Amounts with respect to,
the Debentures or portions thereof which are to be redeemed on that date, other
than Debentures or portions thereof called for redemption on that date which
have been delivered by the Company to the Trustee for cancellation.

               (b) If the giving of notice of redemption shall have been
completed as above provided and funds deposited as required, the Debentures or
portions of Debentures of the series to be redeemed specified in such notice
shall become due and payable on the date and at the place stated in such notice
at the applicable redemption price, together with interest accrued to, but
excluding, the date fixed for redemption, and any Additional Amounts payable
with respect thereto, and interest on such Debentures or portions of Debentures
shall cease to accrue on and after the date fixed for redemption, unless the
Company shall default in the payment of such redemption price, accrued interest
and Additional Amounts with respect to any such Debenture or portion thereof. On
presentation and surrender of such Debentures on or after the date fixed for
redemption at the Place of Payment specified in the notice, said Debentures
shall be paid and redeemed at the applicable redemption price for such series,
together with interest accrued thereon to, but excluding, the date fixed for
redemption and any Additional Amounts payable

                                       21
<PAGE>   29

with respect thereto (but if the date fixed for redemption is an Interest
Payment Date, the interest installment payable on such date shall be payable to
the registered holder at the close of business on the applicable record date
pursuant to Section 2.03).

               (c) Upon presentation of any Debenture of such series which is to
be redeemed in part only, the Company shall execute and the Trustee shall
authenticate and the office or agency where the Debenture is presented shall
make available for delivery to the holder thereof, at the expense of the
Company, a new Debenture or Debentures of the same series, of authorized
denominations in principal amount equal to the unredeemed portion of the
Debenture so presented.

         SECTION 3.04 Sinking Funds for Debentures.

               The provisions of Sections 3.04, 3.05 and 3.06 shall be
applicable to any sinking fund for the retirement of Debentures of a series,
except as otherwise specified as contemplated by Section 2.01 for Debentures of
such series.

               The minimum amount of any sinking fund payment provided for by
the terms of Debentures of any series is herein referred to as a "mandatory
sinking fund payment," and any payment in excess of such minimum amount provided
for by the terms of Debentures of any series is herein referred to as an
"optional sinking fund payment." If provided for by the terms of Debentures for
any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 3.05. Each sinking fund payment shall be
applied to the redemption of Debentures of any series as provided for by the
terms of Debentures of such series and by this Article III.

         SECTION 3.05 Satisfaction of Sinking Fund Payments With Debentures.

               Unless otherwise provided with respect to Debentures of a series
as contemplated by Section 2.01, the Company (i) may deliver outstanding
Debentures of a series (other than any previously called for redemption) and
(ii) may apply as a credit Debentures of a series which have been redeemed
either at the election of the Company pursuant to the terms of such Debentures
or through the application of permitted optional sinking fund payments pursuant
to the terms of such Debentures, in each case in satisfaction of all or any part
of any sinking fund payment with respect to the Debentures of such series
required to be made pursuant to the terms of such Debentures as provided for by
the terms of such series; provided that such Debentures have not been previously
so credited. Such Debentures shall be received and credited for such purpose by
the Trustee at the redemption price specified in such Debentures for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

         SECTION 3.06 Redemption of Debentures for Sinking Fund.

               Not less than 45 days prior to each sinking fund payment date for
any series of Debentures (unless a shorter period shall be satisfactory to the
Trustee), the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms for that series, the portion thereof, if any, which is to
be satisfied by delivering and crediting Debentures of that series pursuant to
Section

                                       22
<PAGE>   30

3.05 and the basis for such credit and will, together with such Officers'
Certificate, deliver to the Trustee any Debentures to be so delivered. Not less
than 30 days before each such sinking fund payment date, the Trustee shall
select the Debentures to be redeemed upon such sinking fund payment date in the
manner specified in Section 3.02 and cause notice of the redemption thereof to
be given in the name of and at the expense of the Company in the manner provided
in Section 3.02. Such notice having been duly given, the redemption of such
Debentures shall be made upon the terms and in the manner stated in Section
3.03.

                                   ARTICLE IV

                       PARTICULAR COVENANTS OF THE COMPANY

               The Company covenants and agrees for each series of the
Debentures as follows:

         SECTION 4.01 Payment of Debentures.

               The Company will duly and punctually pay or cause to be paid the
principal of, any premium and interest on and any Additional Amounts with
respect to the Debentures of that series at the time and place and in the manner
provided herein and established with respect to such Debentures.

               The Company shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal of and premium
(if any) on Debentures of any series, at a rate equal to the then applicable
interest rate on the Debentures of that series to the extent lawful; and it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and any Additional Amount
(without regard to any applicable grace period) on Debentures of any series at
the same rate to the extent lawful.

         SECTION 4.02 Maintenance of Office or Agency.

               So long as any series of the Debentures remain outstanding, the
Company agrees to maintain an office or agency in each Place of Payment, with
respect to each such series and at such other location or locations as may be
designated as provided in this Section 4.02, where (i) Debentures of that series
may be presented for payment, (ii) Debentures of that series may be presented as
hereinabove authorized for registration of transfer and exchange, and (iii)
notices and demands to or upon the Company in respect of the Debentures of that
series and this Indenture may be given or served, such designation to continue
with respect to such office or agency until the Company shall, by written notice
signed by an Officer of the Company and delivered to the Trustee, designate some
other office or agency for such purposes or any of them. 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, 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, notices and demands.

                                       23
<PAGE>   31

         SECTION 4.03 Paying Agent and Holding Sums In Trust.

               (a) If the Company shall appoint one or more paying agents for
all or any series of the Debentures, other than the Trustee, the Company will
cause each such paying agency to execute and deliver to the Trustee an
instrument in which such agent shall agree with the Trustee, subject to the
provisions of this Section:

               (1) that it will hold all sums held by it as such agent for the
         payment of the principal of, any premium or interest on or any
         Additional Amounts with respect to the Debentures of that series
         (whether such sums have been paid to it by the Company or by any other
         obligor of such Debentures) in trust for the benefit of the Persons
         entitled thereto;

               (2) that it will give the Trustee written notice of any failure
         by the Company (or by any other obligor of such Debentures) to make any
         payment of the principal of, any premium or interest on or any
         Additional Amounts with respect to the Debentures of that series when
         the same shall be due and payable;

               (3) that it will, at any time during the continuance of any
         failure referred to in the preceding paragraph (a)(2) above, upon the
         written request of the Trustee, forthwith pay to the Trustee all sums
         so held in trust by such paying agent; and

               (4) that it will perform all other duties of paying agent as set
         forth in this Indenture.

               (b) If the Company shall act as its own paying agent with respect
to any series of the Debentures, it will on or before each due date of the
principal of, any premium or interest on or any Additional Amounts with respect
to Debentures of that series, set aside, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay such principal,
premium, interest or Additional Amounts so becoming due on Debentures of that
series until such sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify in writing the Trustee of such action,
or any failure (by it or any other obligor on such Debentures) to take such
action. Whenever the Company shall have one or more paying agents for any series
of Debentures, it will, prior to 10:00 a.m., New York City time on each due date
of the principal of, any premium or interest on or any Additional Amounts with
respect to any Debentures of that series, deposit with the paying agent a sum
sufficient to pay the principal, premium, interest or Additional Amounts so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium, interest or Additional Amounts, and (unless
such paying agent is the Trustee) the Company will promptly notify the Trustee
of its action or failure so to act.

               (c) Anything in this Section to the contrary notwithstanding, (i)
the agreement to hold sums in trust as provided in this Section is subject to
the provisions of Section 11.04, and (ii) 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 direct any paying agent to pay, to the Trustee all sums
held in trust by the Company or such paying agent, such sums to be held by the
Trustee upon the same terms and conditions as those upon which such sums were
held by the Company

                                       24
<PAGE>   32

or such paying agent; and, upon such payment by any paying agent to the Trustee,
such paying agent shall be released from all further liability with respect to
such money.

         SECTION 4.04 Appointment to Fill Vacancy in Office of Trustee.

               The Company, whenever necessary to avoid or fill a vacancy in the
office of Trustee, will appoint, in the manner provided in Section 7.10, a
Trustee, so that there shall at all times be a Trustee hereunder.

         SECTION 4.05 Certain Expenses.

               Prior to a Security Exchange with respect to Debentures of any
series, the Company shall pay, to the extent provided in the applicable
Declaration of Trust, all debts and obligations (other than with respect to the
Common Securities and Preferred Securities) and cost and expenses of the Trust
that holds any Debentures of such series.

         SECTION 4.06 Additional Amounts.

               If the Debentures of a series expressly provide for the payment
of Additional Amounts, the Company will pay to the holder of any Debenture of
such series Additional Amounts as expressly provided therein. Whenever in this
Indenture there is mentioned, in any context, the payment of the principal of or
any premium or interest on, or in respect of, any Debenture of any series, such
mention shall be deemed to include mention of the payment of Additional Amounts
provided for in this Section 4.06 to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to
the provisions of this Section 4.06 and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in those provisions hereof where such
express mention is not made.

               Unless otherwise provided pursuant to Section 2.01 with respect
to Debentures of any series, if the Debentures of a series provide for the
payment of Additional Amounts, at least ten days prior to the first Interest
Payment Date with respect to that series of Debentures (or if the Debentures of
that series will not bear interest prior to the maturity thereof, the first day
on which a payment of principal and any premium is made), and at least ten days
prior to each date of payment of principal and any premium or interest if there
has been any change with respect to the matters set forth in the below-mentioned
Officers' Certificate, the Company shall furnish the Trustee and the Company's
principal paying agent or paying agents, if other than the Trustee, with an
Officers' Certificate instructing the Trustee and such paying agent or paying
agents whether such payment of principal of and any premium or interest on the
Debentures of that series shall be made to holders of Debentures of that series
who are United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Debentures of that
series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such holders of Debentures and the Company will pay to such
paying agent the Additional Amounts required by this Section 4.06. The Company
covenants to indemnify the Trustee and any paying agent for and to hold them
harmless against any loss, liability or expense reasonably incurred without
negligence or bad faith on their part arising out of or in connection with
actions

                                       25

taken or omitted by any of them in reliance on any Officers' Certificate
furnished pursuant to this Section 4.06.

                       DEBENTUREHOLDERS LISTS AND REPORTS
                         BY THE COMPANY AND THE TRUSTEE

         SECTION 5.01   Company to Furnish Trustee Information as to Names and
                        Addresses of Debentureholders.

               The Company will furnish or cause to be furnished to the Trustee
(a) on each regular record date (as defined in Section 2.03) a list, in such
form as the Trustee may reasonably require, of the names and addresses of the
holders of each series of Debentures as of such regular record date; and (b) at
such other times as the Trustee may request in writing within 30 days after the
receipt by the Company of any such request, a list of similar form and content
as of a date not more than 15 days prior to the time such list is furnished;
provided that in each case the Company shall not be obligated to furnish or
cause to be furnished such list at any time that the list shall not differ in
any respect from the most recent list furnished to the Trustee by the Company;
and provided further that no such list need be furnished for any series for
which the Trustee shall be the Debenture Registrar.

         SECTION 5.02   Trustee to Preserve Information as to Names and
                        Addresses of Debentureholders.

               (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the
holders of Debentures contained in the most recent list furnished to it as
provided in Section 5.01 and as to the names and addresses of holders of
Debentures received by the Trustee in its capacity as Debenture Registrar (if
acting in such capacity).

               (b) The Trustee may destroy any list furnished to it as provided
in Section 5.01 upon receipt of a new list so furnished.

               (c) In case three or more holders of Debentures of a series
(hereinafter referred to as "applicants") apply in writing to the Trustee, and
furnish to the Trustee reasonable proof that each such applicant has owned a
Debenture for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other holders of Debentures of such series or holders of all
Debentures with respect to their rights under this Indenture or under such
Debentures, and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee shall
within five Business Days after the receipt of such application, at its
election, either:

               (1) afford to such applicants access to the information preserved
         at the time by the Trustee in accordance with the provisions of
         subsection (a) of this Section 5.02; or

               (2) inform such applicants as to the approximate number of
         holders of Debentures of such series or of all Debentures, as the case
         may be, whose names and addresses appear in the information preserved
         at the time by the Trustee, in accordance with the provisions of
         subsection (a) of this Section 5.02, and as to the approximate cost of
         mailing to such Debentureholders the form of proxy or other
         communication, if any, specified in such application.

               (d) If the Trustee shall elect not to afford such applicants
access to such information, the Trustee shall, upon the written request of such
applicants, mail to each holder of such series or of all Debentures, as the case
may be, whose name and address appears in the information preserved at the time
by the Trustee in accordance with the provisions of subsection (a) of this
Section 5.02, a copy of the form of proxy or other communication which is
specified in such request, with reasonable promptness after a tender to the
Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of mailing, unless within five days after
such tender, the Trustee shall mail to such applicants and file with the
Commission, together with a copy of the material to be mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would
be contrary to the best interests of the holders of Debentures of such series or
of all Debentures, as the case may be, or would be in violation of applicable
law. Such written statement shall specify the basis of such opinion. If the
Commission, after opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to sustain any of such
objections or if, after the entry of an order sustaining one or more of such
objections, the Commission shall find, after notice and opportunity for hearing,
that all the objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all such
Debentureholders with reasonable promptness after the entry of such order and
the renewal of such tender; otherwise, the Trustee shall be relieved of any
obligation or duty to such applicants respecting their application.

               (e) Each and every holder of the Debentures, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor any paying agent nor any Debenture Registrar shall
be held accountable by reason of the disclosure of any such information as to
the names and addresses of the holders of Debentures in accordance with the
provisions of subsection (c) of this Section 5.02, regardless of the source from
which such information was derived, and that the Trustee shall not be held
accountable by reason of mailing any material pursuant to a request made under
said subsection (c).

         SECTION 5.03  Annual and Other Reports to Be Filed by Company With
                       the Trustee.

               (a) The Company covenants and agrees to file with the Trustee,
within 15 days after the Company is required to file the same with the

Company may be required to file with the Commission pursuant to Section 13 or
Section 15(d) of the Exchange Act; or, if the Company is not required to file
information, documents or reports pursuant to either of such sections, then to

respect of a security listed and registered on a national securities exchange as
may be prescribed from time to time in such rules and regulations. Delivery of
such reports, information and documents to the Trustee is for informational
purposes only and the Trustee's receipt of such shall not constitute
constructive notice of any information contained therein, including the
Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates or on
Certificates provided pursuant to subsection (d) of this Section 5.03).

               (b) The Company covenants and agrees to file with the Trustee and
the Commission, in accordance with the rules and regulations prescribed from
time to time by the Commission, such additional information, documents and
reports with respect to compliance by the Company with the conditions and

such rules and regulations, including such opinions and reports of independent
public accountants as are required by Section 314(a)(2) of the Trust Indenture
Act.

               (c) The Company covenants and agrees to transmit by mail, first
class postage prepaid, or reputable over-night delivery service which provides
for evidence of receipt, to the Debentureholders, as their names and addresses
appear upon the Debenture Register, within 30 days after the filing thereof with
the Trustee, such summaries of any information, documents and reports required
to be filed by the Company pursuant to subsections (a) and (b) of this Section
as may be required by rules and regulations prescribed from time to time by the
Commission.

               (d) The Company covenants and agrees to furnish to the Trustee,
on or before May 15 in each calendar year in which any of the Debentures are
outstanding, or on or before such other day in each calendar year as the Company
and the Trustee may from time to time agree upon, a Certificate as to his or her
knowledge of the Company's compliance with all conditions and covenants under
this Indenture. For purposes of this subsection (d), such compliance shall be
determined without regard to any period of grace or requirement of notice
provided under this Indenture.

         SECTION 5.04 Trustee to Transmit Annual Report to Debentureholders.

               (a) The Trustee shall transmit to Debentureholders such reports
concerning the Trustee and its actions under this Indenture as may be required
pursuant to the Trust Indenture Act at the times and in the manner provided
pursuant thereto. If required by Section 313(a) of the Trust Indenture Act, the
Trustee shall, within 60 days after each May 15 following the date of this
Indenture, commencing May 15, 2001, deliver to Debentureholders a brief report,
dated as of such May 15, which complies with the provisions of such Section
313(a).

               (b) The Trustee shall comply with Section 313(b) and 313(c) of
the Trust Indenture Act.

               (c) A copy of each such report shall, at the time of such
transmission to Debentureholders, be filed by the Trustee with the Company, with
each stock exchange upon which any Debentures are listed (if so listed) and also
with the Commission. The Company agrees to notify the Trustee when any
Debentures become listed on any stock exchange.

                  REMEDIES OF THE TRUSTEE AND DEBENTUREHOLDERS
                               ON EVENT OF DEFAULT

         SECTION 6.01 Events of Default Defined.

               (a) Whenever used herein with respect to Debentures of a
particular series, "Event of Default" means any one or more of the following
events which has occurred and is continuing:

               (1) default in the payment of any installment of interest upon or
         any Additional Amounts with respect to any of the Debentures of that
         series, as and when the same shall become due and payable, and
         continuance of such default for a period of 30 days; provided, however,
         that a valid extension of an interest payment period by the Company, in
         accordance with the terms of Debentures of that series established
         pursuant to Section 2.01 hereof, shall not constitute a default in the
         payment of interest for this purpose;

               (2) default (i) in the payment of the principal of (and premium,
         if any, on) any of the Debentures of that series as and when the same
         shall become due and payable, whether at maturity, upon redemption, by
         declaration of acceleration or otherwise, or (ii) in any payment
         required by any sinking or analogous fund established with respect to
         that series, and in the case of this clause (ii) only, continuance of
         such default for a period of 30 days;

               (3) failure on the part of the Company duly to observe or
         perform, in any material respect, any other of the covenants or
         agreements on the part of the Company with respect to that series
         contained in such Debentures or otherwise established with respect to
         that series of Debentures pursuant to Section 2.01 hereof or contained
         in this Indenture (other than a covenant or agreement which has been
         expressly included in this Indenture solely for the benefit of one or
         more series of Debentures other than such series) for a period of 90
         days after the date on which written notice of such failure, requiring
         the same to be remedied and stating that such notice is a "Notice of
         Default" hereunder, shall have been given to the Company by the
         Trustee, by registered or certified mail, or to the Company and the
         Trustee by the holders of at least 25% in principal amount of the
         Outstanding Debentures of the series affected by the Default;

               (4) the Company pursuant to or within the meaning of any
         Bankruptcy Law:

                   (A) commences a voluntary case,

                   (B) consents to the entry of an order for relief against it
               in an involuntary case,

                   (C) consents to the appointment of a Bankruptcy Custodian of
               it or for all or for a substantial part of its property, or

                                       29
<PAGE>   37

                   (D) makes a general assignment for the benefit of its
               creditors;

               (5) a court of competent jurisdiction enters an order or decree
         under any Bankruptcy Law that remains unstayed and in effect for 90
         days and that:

                   (A) is for relief against the Company as debtor in an
               involuntary case,

                   (B) appoints a Bankruptcy Custodian of the Company or a
               Bankruptcy Custodian for all or for a substantial part of the
               property of the Company, or

                   (C) orders the liquidation of the Company; or

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

               The term "Bankruptcy Custodian" means any receiver, trustee,
assignee, liquidator or similar official under any Bankruptcy Law.

               (b) In each and every such case specified in clause (1), (2), (3)
or (6) of Section 6.01(a), unless the principal of all the Debentures of that
series shall have already become due and payable, either the Trustee or the
holders of not less than 25% in aggregate principal amount of the Outstanding
Debentures of the series affected by the Default, by notice in writing to the
Company (and to the Trustee if given by such Debentureholders), may declare the
principal of all the Debentures of that series to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable, anything contained in this Indenture or in the
Debentures of that series or established with respect to that series pursuant to
Section 2.01 to the contrary notwithstanding. If an Event of Default specified
in clause (5) or (6) of Section 6.01(a) occurs, such amounts shall ipso facto
become and be immediately due and payable without any declaration, notice or
other act on the part of the Trustee or any holder. Payment of principal of, any
premium and interest on and any Additional Amounts with respect to such
Debentures shall remain subordinated to the extent provided in Article XIV
notwithstanding that such amount shall become immediately due and payable as
herein provided.

               (c) Section 6.01(b), however, is subject to the condition that
if, at any time after the principal of the Debentures of that series shall have
been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay all matured installments of interest upon and any Additional
Amounts with respect to all the Debentures of that series and the principal of
(and premium, if any, on) any and all Debentures of that series which shall have
become due otherwise than by acceleration (with interest upon such principal and
premium, if any, and, to the extent that such payment is enforceable under
applicable law, upon overdue installments of interest and Additional Amounts, at
the rate per annum expressed in the Debentures of that series to the date of
such payment or deposit) and the amount payable to the Trustee under Section
7.06, and any and all Defaults under the Indenture, other than the nonpayment of
principal on Debentures of that series which shall not have become due by their
terms, shall have been remedied or waived as provided in Section 6.06 then and
in every such case the holders of a majority in aggregate principal amount

                                       30
<PAGE>   38

of the Outstanding Debentures of the series affected by the Default (subject to,
in the case of any series of Debentures held as trust assets of a Trust and with
respect to which a Security Exchange has not theretofore occurred, such holders'
obtaining such consent of the holders of the Preferred Securities and the Common
Securities of such Trust as may be required under the Declaration of Trust of
such Trust), by written notice to the Company and to the Trustee, may rescind
and annul such declaration and its consequences with respect to that series of
Debentures; but no such rescission and annulment shall extend to or shall affect
any subsequent Default, or shall impair any right consequent thereon.

               (d) In case the Trustee shall have proceeded to enforce any right
with respect to Debentures of that series under this Indenture and such
proceedings shall have been discontinued or abandoned because of such rescission
or annulment or for any other reason or shall have been determined adversely to
the Trustee, then and in every such case the Company and the Trustee shall be
restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Company and the Trustee shall continue as
though no such proceedings had been taken.

               (e) If, prior to a Security Exchange with respect to the
Debentures of any series, a Default with respect to the Debentures of such
series shall have occurred, the Company expressly acknowledges that under the
circumstances set forth in the applicable Declaration of Trust, any holder of
Preferred Securities of the applicable Trust may, subject to Section 6.04 and
Section 6.06, enforce directly against the Company the applicable Property
Trustee's rights hereunder. In furtherance of the foregoing and for the
avoidance of any doubt, the Company acknowledges that, under the circumstances
described in the applicable Declaration of Trust, any such holder of Preferred
Securities, in its own name, in the name of the applicable Trust or in the name
of the holders of the Preferred Securities issued by such Trust, may institute
or cause to be instituted a proceeding, including, without limitation, any suit
in equity, an action at law or other judicial or administrative proceeding, to
enforce the applicable Property Trustee's rights hereunder directly against the
Company as issuer of the applicable series of Debentures, and may prosecute such
proceeding to judgment or final decree, and enforce the same against the
Company.

        SECTION 6.02  Covenant of Company to Pay to Trustee Whole
                      Amount Due on Debentures on Default in Payment.

               (a) The Company covenants that (1) in case default shall be made
in the payment of any installment of interest on or any Additional Amounts with
respect to any of the Debentures of a series, or any payment required by any
sinking or analogous fund established with respect to that series as and when
the same shall have become due and payable, and such Default shall have
continued for a period of 30 days, or (2) in case default shall be made in the
payment of the principal of (or premium, if any, on) any of the Debentures of a
series when the same shall have become due and payable, whether upon maturity of
the Debentures of a series or upon redemption or upon declaration or otherwise,
then, upon demand of the Trustee, the Company will pay to the Trustee, for the
benefit of the holders of the Debentures of that series, the whole amount that
then shall have become due and payable on all such Debentures for principal, any
premium, interest or Additional Amounts, as the case may be, with interest upon
the overdue principal (and premium, if any) and (to the extent that payment of
such interest is

                                       31
<PAGE>   39

enforceable under applicable law and without duplication of any other amounts
paid by the Company or the applicable Trust in respect thereof) upon overdue
installments of interest and Additional Amounts at the rate per annum expressed
in the Debentures of that series; and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, and the
amount payable to the Trustee under Section 7.06.

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

               (c) In case of any receivership, insolvency, liquidation,
bankruptcy, reorganization, readjustment, arrangement, composition or other
judicial proceedings affecting the Company, any other obligor on such
Debentures, or the creditors or property of either, the Trustee shall have the
power to intervene in such proceedings and take any action therein that may be
permitted by the court and shall (except as may be otherwise provided by law) be
entitled to file such proofs of claim and other papers and documents as may be
necessary or advisable in order to have the claims of the Trustee and of the
holders of Debentures of such series allowed for the entire amount due and
payable by the Company or such other obligor under the Indenture at the date of
institution of such proceedings and for any additional amount which may become
due and payable by the Company or such other obligor after such date, and to
collect and receive any moneys or other property payable or deliverable on any
such claim, and to distribute the same after the deduction of the amount payable
to the Trustee under Section 7.06; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the holders of
Debentures of such series to make such payments to the Trustee, and, in the
event that the Trustee shall consent to the making of such payments directly to
such Debentureholders, to pay to the Trustee any amount due it under Section
7.06.

               (d) All rights of action and of asserting claims under this
Indenture, or under any of the terms established with respect to Debentures of
that series, may be enforced by the Trustee without the possession of any of
such Debentures, or the production thereof at any trial or other proceeding
relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for payment to the Trustee of any
amounts due under Section 7.06, be for the ratable benefit of the holders of the
Debentures of such series.

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

                                       32
<PAGE>   40

               Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Debentureholder
any plan of reorganization, arrangement, adjustment or composition affecting the
Debentures of that series or the rights of any holder thereof or to authorize
the Trustee to vote in respect of the claim of any Debentureholder in any such
proceeding.

         SECTION 6.03 Application of Moneys Collected by Trustee.

               Any moneys collected by the Trustee pursuant to this Article VI
with respect to a particular series of Debentures shall be applied in the order
following, at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal, premium, interest or
Additional Amounts, upon presentation of the several Debentures of that series,
and stamping thereon the payment, if only partially paid, and upon surrender
thereof if fully paid:

               First: To the payment of costs and expenses of collection and of
         all amounts payable to the Trustee under Section 7.06;

               Second: To the payment of all Senior Debt of the Company if and
         to the extent required by Article XIV;

               Third: To the payment of the amounts then due and unpaid upon
         Debentures of such series for principal, premium, interest and
         Additional Amounts, in respect of which or for the benefit of which
         such money has been collected, ratably, without preference or priority
         of any kind, according to the amounts due and payable on such
         Debentures for principal, premium, interest and Additional Amounts,
         respectively; and

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

         SECTION 6.04 Limitation on Suits by Holders of Debentures.

               No holder of any Debenture of any series shall have any right by
virtue or by availing of any provision of this Indenture to institute any suit,
action or proceeding in equity or at law upon or under or with respect to this
Indenture or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless (a) such holder previously shall have given to the
Trustee written notice of an Event of Default and of the continuance thereof
with respect to Debentures of such series specifying such Event of Default, as
hereinbefore provided, (b) the holders of not less than 25% in aggregate
principal amount of the Debentures of such series then Outstanding shall have
made written request upon the Trustee to institute such action, suit or
proceeding in its own name as trustee hereunder, (c) such holder or holders
shall have furnished to the Trustee indemnity satisfactory to it against the
costs, expenses and liabilities to be incurred therein or thereby, (d) the
Trustee for 60 days after its receipt of such notice, request and furnishing of
indemnity, shall have failed to institute any such action, suit or proceeding
and (e) during such 60 day period, the holders of a majority in principal amount
of the Outstanding Debentures of that series do not give the Trustee a direction
inconsistent with the request; it being understood and intended, and being
expressly covenanted by the taker and holder of every Debenture of such series
with every other such taker and holder and Trustee, that no one or more holders
of Debentures of such series shall have any right in any manner whatsoever by
virtue or

                                       33
<PAGE>   41

by availing of any provision of this Indenture to affect, disturb or prejudice
the rights of the holders of any other of such Debentures, or to obtain or seek
to obtain priority over or preference to any other such holder, or to enforce
any right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Debentures of such series.
For the protection and enforcement of the provisions of this Section, each and
every Debentureholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

               Notwithstanding any other provisions of this Indenture, however,
the right of any holder of any Debenture to receive payment of the principal of,
any premium and interest on and any Additional Amounts with respect to such
Debenture, as therein provided, on or after the respective due dates expressed
in such Debenture (or in the case of redemption, on the redemption date), or to
institute suit for the enforcement of any such payment on or after such
respective dates or redemption date, shall not be impaired or affected without
the consent of such holder.

         SECTION 6.05  Remedies Cumulative; Delay or Omission in Exercise of
                       Rights Not Waiver of Default.

               (a) All powers and remedies given by this Article VI to the
Trustee or to the Debentureholders shall, to the extent permitted by law, be
deemed cumulative and not exclusive of any others thereof or of any other powers
and remedies available to the Trustee or the holders of the Debentures, by
judicial proceedings or otherwise, to enforce performance or observance of the
covenants and agreements contained in this Indenture or otherwise established
with respect to such Debentures.

               (b) No delay or omission of the Trustee or of any holder of any
of the Debentures to exercise any right or power accruing upon any Event of
Default occurring and continuing as aforesaid shall impair any such right or
power, or shall be construed to be a waiver of any such default or an
acquiescence therein; and, subject to the provisions of Section 6.04, every
power and remedy given by this Article or by law to the Trustee or to the
Debentureholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Debentureholders.

         SECTION 6.06  Rights of Holders of Majority in Principal Amount of
                       Debentures to Direct Trustee and to Waive Defaults.

               The holders of a majority in aggregate principal amount of the
Debentures of any series at the time Outstanding, determined in accordance with
Section 8.04 (with, in the case of any series of Debentures held as trust assets
of a Trust and with respect to which a Security Exchange has not theretofore
occurred, such holders' obtaining such consent of holders of the Preferred
Securities and the Common Securities of such Trust as may be required under the
Declaration of Trust of such Trust), shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee with respect
to such series; provided, however, that such direction shall not be in conflict
with any rule of law or with this Indenture or unduly prejudicial to the rights

accordance with Section 8.04 not parties thereto. Subject to the provisions of
Section 7.01, the Trustee shall have the right to decline to follow any such
direction if the Trustee in good faith shall, by a Responsible Officer or
Officers of the Trustee, determine that the proceeding so directed would involve
the Trustee in personal liability. The holders of a majority in aggregate
principal amount of the Debentures of any series at the time Outstanding
affected thereby, determined in accordance with section 8.04 (with, in the case
of any series of Debentures held as trust assets of a Trust and with respect to
which a Security Exchange has not theretofore occurred, such holders' obtaining
such consent of holders of the Preferred Securities and the Common Securities of
such Trust as may be required under the Declaration of Trust of such Trust), may
on behalf of the holders of all of the Debentures of such series waive any past
Default in the performance of any of the covenants contained herein or
established pursuant to Section 2.01 with respect to such series and its
consequences, except a Default in the payment of the principal of, any premium
or interest on or any Additional Amounts with respect to any of the Debentures
of that series as and when the same shall become due by the terms of such
Debentures otherwise than by acceleration (unless such Default has been cured
and a sum sufficient to pay all matured installments of principal, any premium,
interest and any Additional Amounts has been deposited with the Trustee (in
accordance with Section 6.01(c)), or by the terms of Debentures of that series.
Upon any such waiver, the Default covered thereby shall be deemed to be cured
for all purposes of this Indenture and the Company, the Trustee and the holders
of the Debentures of such series shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

         SECTION 6.07  Trustee to Give Notice of Defaults Known To It,
                       But May Withhold in Certain Circumstances.

               The Trustee shall, within 90 days after the occurrence of a
Default with respect to a particular series, transmit by mail, first class
postage prepaid, to the holders of Debentures of that series, as their names and
addresses appear upon the Debenture Register, notice of all Defaults with
respect to that series known to the Trustee, unless such Defaults shall have
been cured before the giving of such notice (the term "Defaults" for the
purposes of this Section being hereby defined to be the events specified in
subsections (1), (2), (3), (4), (5) and (6) of Section 6.01(a), not including
any periods of grace provided for therein and irrespective of the giving of
notice provided for by subsection (3) of Section 6.01(a)); provided that, except
in the case of default in the payment of the principal of, any premium or
interest on or any Additional Amounts with respect to any of the Debentures of
that series or in the payment of any sinking fund installment established with
respect to that series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee, or a
trust committee of directors and/or Responsible Officers, of the Trustee in good
faith determine that the withholding of such notice is in the interests of the
holders of Debentures of that series; provided further, that in the case of any
Default of the character specified in Section 6.01(a)(3) with respect to
Debentures of such series no such notice to the holders of the Debentures of
that series shall be given until at least 30 days after the occurrence thereof.

               The Trustee shall not be deemed to have knowledge of any Default,
except (i) a Default under subsection (a)(1) or (a)(2) of Section 6.01 (other
than a Default in the payment of any Additional Amounts with respect to
Debentures of such series) as long as the Trustee is

                                       35

acting as paying agent for such series of Debentures or (ii) any Default as to
which a Responsible Officer of the Trustee shall have received written notice.

         SECTION 6.08  Requirements of an Undertaking to Pay Costs in Certain
                       Suits Under Indenture or Against Trustee.

               All parties to this Indenture agree, and each holder of any
Debentures by his or her acceptance thereof shall be deemed to have agreed, that
any court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees and expenses, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Debentureholder, or group of
Debentureholders, holding more than 10% in aggregate principal amount of the
Outstanding Debentures of any series, or to any suit instituted by any
Debentureholder for the enforcement of the payment of the principal of, any
premium or interest on or any Additional Amounts with respect to any Debenture
of such series, on or after the respective due dates expressed in such Debenture
or established pursuant to this Indenture.

                                  ARTICLE VII

                             CONCERNING THE TRUSTEE

         SECTION 7.01 Duties of Trustee.

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

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

               (1) prior to the occurrence of an Event of Default with respect
         to Debentures of a series and after the curing or waiving of all such
         Events of Default with respect to that series which may have occurred:

                  (i) the duties and obligations of the Trustee shall with
               respect to Debentures of such series be determined solely by the
               express provisions of this

                                       36
<PAGE>   44

               Indenture and the Trust Indenture Act, and the Trustee shall
               not be liable with respect to Debentures of such series except
               for the performance of such duties and obligations as are
               specifically set forth in this Indenture, and no implied
               covenants or obligations shall be read into this Indenture
               against the Trustee; and

                  (ii) in the absence of bad faith on the part of the Trustee,
               the Trustee may with respect to Debentures of such series
               conclusively rely, as to the truth of the statements and the
               correctness of the opinions expressed therein, upon any
               certificates or opinions furnished to the Trustee and conforming
               to the requirements of this Indenture; but in the case of any
               such certificates or opinions which by any provision hereof are
               specifically required to be furnished to the Trustee, the Trustee
               shall be under a duty to examine the same to determine whether or
               not they conform to the requirements of this Indenture but need
               not confirm or investigate the accuracy of mathematical
               calculations or other facts stated therein;

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

               (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the holders of not less than a majority in principal
         amount of the Debentures of any series at the time Outstanding (or, as
         the case may be, the holders of a majority of outstanding Preferred
         Securities or Common Securities issued by the applicable Trust)
         relating to the time, method and place of conducting any proceeding for
         any remedy available to the Trustee, or exercising any trust or power
         conferred upon the Trustee under this Indenture with respect to the
         Debentures of that series;

               (4) none of the provisions contained in this Indenture shall
         require the Trustee to expend or risk its own funds or otherwise incur
         personal financial liability in the performance of any of its duties or
         in the exercise of any of its rights or powers, if there is reasonable
         ground for believing that the repayment of such funds or liability is
         not reasonably assured to it under the terms of this Indenture or
         adequate indemnity against such risk is not furnished to it;

               (5) If at any time the Trustee hereunder is not the same Person
         as the Property Trustee under a Declaration of Trust:

                  (A) whenever a reference is made herein to a Security
               Exchange, the Trustee shall be entitled to assume that no such
               Security Exchange has occurred so long as the Debentures of the
               applicable series are or continue to be registered in the name of
               such Property Trustee, and the Trustee shall be charged with
               notice or knowledge of such Security Exchange only upon either
               (i) written notice thereof given to the Trustee by the Regular
               Trustees under such Declaration of Trust or (ii) registration of
               a Global Debenture representing such Debentures in the name of a
               Depositary or its nominee; and

                                       37
<PAGE>   45

                  (B) the Trustee shall not be charged with notice or knowledge
               that any Person (other than the Depositary) is a holder of
               Preferred Securities or Common Securities issued by the
               applicable Trust for any purpose under this Indenture, including,
               without limitation, Section 6.01(e), Section 6.06, Section 9.02
               and Section 13.12, unless and until the Trustee is furnished with
               a list of such holders by such Property Trustee or the Regular
               Trustees under such Declaration of Trust. The Trustee may
               conclusively rely and shall be protected in relying on such list;

               (6) The Trustee shall have no duty or obligation under this
         Indenture, including, without limitation, Section 6.06 and Section
         9.02, to determine whether the registered holder of any Debenture has
         obtained the requisite consent of the holders of Preferred Securities
         and Common Securities required under a Declaration of Trust, and shall
         be protected in acting upon the consent, direction or other instruction
         of the registered holder of such Debenture;

               (7) Notwithstanding Section 13.12 hereof, the Trustee shall not,
         and shall not be deemed to, owe any fiduciary duty to the holders of
         Preferred Securities or Common Securities issued by a Trust and shall
         not be liable to any such holder (other than for the willful misconduct
         or negligence of the Trustee) if the Trustee in good faith (i) pays
         over or distributes to a registered holder of the Debentures of the
         applicable series or to the Company or to any other Person, cash,
         property or securities to which such holders of Preferred Securities or
         Common Securities shall be entitled or (ii) takes any action or omits
         to take any action at the request of such registered holder of such
         Debentures. Nothing in this Section 7.01(b)(7) shall affect the
         obligation of any other such Person to hold such payment for the
         benefit of, and to pay such amount over to, such holders of Preferred
         Securities or Common Securities or their representatives;

               (8) 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 Article VII; and

               (9) this subsection (b) shall not be construed to limit the
         effect of Section 7.01(a).

         SECTION 7.02 Certain Rights of the Trustee.

               Except as otherwise provided in Section 7.01:

               (a) The Trustee may conclusively rely and shall be protected in
acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
security or other paper or document believed by it to be genuine and to have
been signed or presented by the proper party or parties;

               (b) Any request, direction, order or demand of the Company
mentioned herein shall be sufficiently evidenced by a Board Resolution or an
instrument signed in the name of the Company by an Officer of the Company
(unless other evidence in respect thereof is specifically prescribed herein);

                                       38
<PAGE>   46

               (c) The Trustee may consult with counsel of its selection 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 or suffered
or omitted hereunder in good faith and in reliance thereon;

               (d) The Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Debentureholders (or, as the case may be, the holders of
Preferred Securities or Common Securities issued by the applicable Trust),
pursuant to the provisions of this Indenture, unless such Debentureholders (or
such holders) shall have furnished to the Trustee security or indemnity
satisfactory to it against the costs, expenses and liabilities which may be
incurred therein or thereby; nothing herein contained shall, however, relieve
the Trustee of the obligation, upon the occurrence of an Event of Default with
respect to a series of the Debentures (which has not been cured or waived) to
exercise with respect to Debentures of that series such of the rights and powers
vested in it by this Indenture, and to use the same degree of care and skill in
their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs;

               (e) The Trustee shall not be liable for any action taken or
omitted to be taken by it in good faith and believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Indenture;

               (f) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
security, or other papers or documents, unless requested in writing so to do by
the holders of not less than a majority in principal amount of the Outstanding
Debentures of the particular series affected thereby (determined as provided in
Section 8.04); provided, however, that if the payment within a reasonable time
to the Trustee of the costs, expenses or liabilities likely to be incurred by it
in the making of such investigation is, in the opinion of the Trustee, not
reasonably assured to the Trustee by the security afforded to it by the terms of
this Indenture, the Trustee may require indemnity satisfactory to it against
such costs, expenses or liabilities as a condition to so proceeding. The
reasonable expense of every such examination shall be paid by the Company or, if
paid by the Trustee, shall be repaid by the Company upon demand;

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

               (h) The rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and to each agent, custodian and other Person
employed to act hereunder.

                                       39
<PAGE>   47

         SECTION 7.03 Trustee's Disclaimer.

               (a) The recitals contained herein and in the Debentures (other
than the Certificate of Authentication on the Debentures) shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.

               (b) The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Debentures.

               (c) The Trustee shall not be accountable for the use or
application by the Company of any of the Debentures or of the proceeds of such
Debentures, or for the use or application of any moneys paid over by the Trustee
in accordance with any provision of this Indenture or established pursuant to
Section 2.01, or for the use or application of any moneys received by any paying
agent other than the Trustee.

         SECTION 7.04  May Own Debentures.

               The Trustee or any paying agent or Debenture Registrar, in its
individual or any other capacity, may become the owner or pledgee of Debentures
and, subject to Sections 7.08 and 7.13, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, paying agent or Debenture
Registrar.

         SECTION 7.05  Moneys Received by Trustee to Be Held In Trust
                       Without Interest.

               Subject to the provisions of Section 11.05, all moneys received
by the Trustee shall, until used or applied as herein provided, be held in trust
for the purposes for which they were received, but need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any moneys received by it hereunder except such as it
may agree in writing to pay thereon.

         SECTION 7.06  Compensation, Reimbursement and Indemnity.

               (a) The Company covenants and agrees to pay to the Trustee from
time to time, and the Trustee shall be entitled to, such compensation as the
Company and the Trustee shall from time to time agree in writing (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) for all services rendered by it in the execution of
the trusts hereby created and in the exercise and performance of any of the
powers and duties hereunder of the Trustee, and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the reasonable expenses and disbursements of its counsel and of all persons
not regularly in its employ) except any such expense, disbursement or advance as
may arise from its negligence or bad faith. The Company also covenants to
indemnify each of the Trustee and its officers, agents, directors and employees
for, and to hold them harmless against, any loss, liability or expense including
taxes (other than taxes based upon, measured by or determined by the income,
profit, franchise or doing business of the Trustee) incurred without negligence
or bad faith on the part of the Trustee and arising out of or in connection with
the acceptance or administration of this trust, including the reasonable costs
and expenses of defending itself

                                       40
<PAGE>   48

against any claim of liability in the premises. The provisions of this Section
7.06 shall survive the termination of this Indenture and resignation or removal
of the Trustee.

               (b) The obligations of the Company under this Section to
compensate and indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to that
of the Debentures upon all property and funds held or collected by the Trustee
as such, except funds held in trust for the benefit of the holders of particular
Debentures.

               (c) When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(a)(4) or (5) occurs, the expenses and
the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

         SECTION 7.07  Right of Trustee to Rely on Certificate of Officers of
                       Company Where No Other Evidence Specifically Prescribed.

               Except as otherwise provided in Sections 7.01 and 7.02, whenever
in the administration of the provisions of this Indenture the Trustee shall deem
it necessary or desirable that a matter be proved or established prior to taking
or suffering or omitting to take any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee and such certificate, in the absence of negligence or bad faith on the
part of the Trustee, shall be full warrant to the Trustee for any action taken,
suffered or omitted to be taken by it under the provisions of this Indenture
upon the faith thereof.

         SECTION 7.08  Disqualification; Conflicting Interests.

               If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and
the Company shall in all respects comply with the provisions of Section 310(b)
of the Trust Indenture Act. Nothing herein shall prevent the Trustee from filing
with the Commission the application referred to in the second to last paragraph
of said Section 310(b).

         SECTION 7.09  Requirements for Eligibility of Trustee.

               There shall at all times be a Trustee with respect to the
Debentures issued hereunder which shall at all times be a corporation or banking
association organized and doing business under the laws of the United States, or
a corporation or other Person permitted to act as trustee by the Commission,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $50 million, 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 aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. The
Company may not, nor may any Person directly or indirectly controlling,
controlled by, or under common control with the

                                       41
<PAGE>   49

Company, serve as Trustee. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 7.10.

         SECTION 7.10  Resignation of Trustee and Appointment of Successor.

               (a) The Trustee or any successor hereafter appointed, may at any
time resign with respect to the Debentures of one or more series by giving
written notice thereof to the Company and by transmitting notice of resignation
by mail, first class postage prepaid, to the Debentureholders of such series, as
their names and addresses appear upon the Debenture Register. Upon receiving
such notice of resignation, the Company shall promptly appoint a successor
trustee with respect to Debentures of such series by written instrument, in
duplicate, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If no successor trustee shall
have been so appointed and have accepted appointment within 60 days after the
mailing of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee with
respect to Debentures of such series, or any Debentureholder of that series who
has been a bona fide holder of a Debenture or Debentures for at least six months
may, subject to the provisions of Section 6.08, on behalf of himself and all
others similarly situated, petition any such court for the appointment of a
successor trustee. Such court may thereupon after such notice, if any, as it may
deem proper and prescribe, appoint a successor trustee.

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

               (1) the Trustee shall fail to comply with the provisions of
         Section 7.08 after written request therefor by the Company or by any
         Debentureholder who has been a bona fide holder of a Debenture or
         Debentures for at least six months; or

               (2) the Trustee shall cease to be eligible in accordance with the
         provisions of Section 7.09 and shall fail to resign after written
         request therefor by the Company or by any such Debentureholder; or

               (3) the Trustee shall become incapable of acting, or shall be
         adjudged bankrupt or insolvent, or a receiver of the Trustee or of its
         property shall be appointed, or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation, then, in any such case,
         the Company may remove the Trustee with respect to all Debentures and
         appoint a successor trustee by written instrument, in duplicate,
         executed by order of the Board of Directors, one copy of which
         instrument shall be delivered to the Trustee so removed and one copy to
         the successor trustee. If no successor trustee shall have been so
         appointed and have accepted appointment within 30 days after the
         mailing of such notice of removal, the Trustee so removed may petition
         any court of competent jurisdiction for the appointment of a successor
         trustee with respect to Debentures of such series, or any
         Debentureholder of that series who has been a bona fide holder of a
         Debenture or Debentures for at least six months may, subject to the
         provisions of Section 6.08, on behalf of himself and all others
         similarly situated, petition any such court for the removal of the
         Trustee and the

                                       42

         appointment of a successor trustee. Such court may thereupon after such
         notice, if any, as it may deem proper and prescribe, remove the Trustee
         and appoint a successor trustee.

               (c) The holders of a majority in aggregate principal amount of
the Debentures of any series at the time Outstanding may at any time remove the
Trustee with respect to such series and appoint a successor trustee.

               (d) Any resignation or removal of the Trustee and appointment of
a successor trustee with respect to the Debentures of a series pursuant to any
of the provisions of this Section shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 7.11.

               (e) Any successor trustee appointed pursuant to this Section may
be appointed with respect to the Debentures of one or more series or all of such
series, and at any time there shall be only one Trustee with respect to the
Debentures of any particular series.

         SECTION 7.11 Acceptance by Successor to Trustee.

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

               (b) In case of the appointment hereunder of a successor trustee
with respect to the Debentures of one or more (but not all) series, the Company,
the retiring Trustee and each successor trustee with respect to the Debentures
of one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor trustee shall accept such appointment and which shall (1)
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Debentures of that
or those series to which the appointment of such successor trustee relates, (2)
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Debentures of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee and that no Trustee shall be responsible for any act or
failure to act on the part of any other Trustee hereunder; and upon the
execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall

                                       43
<PAGE>   51

become effective to the extent provided therein, such retiring Trustee shall
with respect to the Debentures of that or those series to which the appointment
of such successor trustee relates have no further responsibility for the
exercise of rights and powers or for the performance of the duties and
obligations vested in the Trustee under this Indenture, and each such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Debentures of that or those series to which the appointment of such
successor trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor trustee, to the extent contemplated by such supplemental indenture,
the property and money held by such retiring Trustee hereunder with respect to
the Debentures of that or those series to which the appointment of such
successor trustee relates.

               (c) Upon request of any such successor trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor trustee all such rights, power and trusts referred
to in paragraph (a) or (b) of this Section 7.11, as the case may be.

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

               (e) Upon acceptance of appointment by a successor trustee as
provided in this Section 7.11, the successor trustee shall transmit notice of
the succession of such trustee hereunder by mail, first class postage prepaid,
to the Debentureholders, as their names and addresses appear upon the Debenture
Register.

         SECTION 7.12  Successor to Trustee by Merger, Consolidation or
                       Succession to Business.

               Any corporation or banking association into which the Trustee may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such corporation shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding. In case any Debentures shall have been authenticated,
but not made available for delivery, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and make available for delivery the Debentures so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Debentures.

         SECTION 7.13  Preferential Collection of Claims Against the Company.

               The Trustee shall comply with Section 311(a) of the Trust
Indenture Act, excluding any creditor relationship described in Section 311(b)
of the Trust Indenture Act. A Trustee who has resigned or been removed shall be
subject to Section 311(a) of the Trust Indenture Act to the extent included
therein as though such resignation or removal, as the case may be, had not
occurred.

                                  ARTICLE VIII

                            CONCERNING THE DEBENTURES

         SECTION 8.01  Evidence of Action by Debentureholders.

               Whenever in this Indenture it is provided that the holders of a
majority or specified percentage in aggregate principal amount of the Debentures
of a particular series may take any action (including the making of any demand
or request, the giving of any notice, consent or waiver or the taking of any
other action), the fact that at the time of taking any such action the holders
of such majority or specified percentage of that series have joined therein may
be evidenced by any instrument or any number of instruments of similar tenor
executed by such holders of Debentures of that series in person or by agent or
proxy appointed in writing.

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

         SECTION 8.02  Proof of Execution of Instruments and of Holding
                       of Debentures.

               Subject to the provisions of Sections 7.01 and 7.02, proof of the
execution of any instrument by a Debentureholder (such proof will not require
notarization) or his agent or proxy and proof of the holding by any Person of
any of the Debentures shall be sufficient if made in the following manner:

               (a) The fact and date of the execution by any such Person of any
instrument may be proved in any reasonable manner acceptable to the Trustee.

               (b) The ownership of Debentures shall be proved by the Debenture
Register of such Debentures or by a certificate of the Debenture Registrar
thereof.

               (c) The Trustee may require such additional proof of any matter
referred to in this Section as it shall deem necessary.

                                       45
<PAGE>   53

         SECTION 8.03  Who May Be Deemed Owners of Debentures.

               Prior to the due presentment for registration of transfer of any
Debenture, the Company, the Trustee, any paying agent and any Debenture
Registrar may deem and treat the Person in whose name such Debenture shall be
registered in the Debenture Register as the absolute owner of such Debenture
(whether or not such Debenture shall be overdue and notwithstanding any notice
of ownership or writing thereon made by anyone other than the Debenture
Registrar) for the purpose of receiving payment of or on account of the
principal of, premium, if any, and (subject to Section 2.03) interest on such
Debenture and for all other purposes; and neither the Company nor the Trustee
nor any paying agent nor any Debenture Registrar shall be affected by any notice
to the contrary.

         SECTION 8.04  Debentures Owned by the Company or Controlled or
                       Controlling Companies Disregarded for Certain Purposes.

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

         SECTION 8.05  Instruments Executed by Debentureholders Bind
                       Future Holders.

                  At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 8.01, of the taking of any action by the holders
of the majority or percentage in aggregate principal amount of the Debentures of
a particular series specified in this Indenture in connection with such action,
any holder of a Debenture of that series which is shown by the evidence to be
included in the Debentures the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as
provided in Section 8.02, revoke such action so far as concerns such Debenture.
Except as aforesaid any such action taken by the holder of any Debenture shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Debenture, and of any Debenture issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Debenture. Any action taken
by the holders of the majority or percentage in aggregate principal amount of
the Debentures of a particular series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Debentures of that series.

                             SUPPLEMENTAL INDENTURES

         SECTION 9.01 Without Consent of Debentureholders.

               In addition to any supplemental indenture otherwise authorized by
this Indenture, the Company and the Trustee may from time to time and at any
time enter into an indenture or indentures supplemental hereto (which shall
conform to the provisions of the Trust Indenture Act as then in effect), without
the consent of the Debentureholders, for one or more of the following purposes:

               (a) to evidence the succession of another corporation or other
entity to the Company, and the assumption by any such successor of the
obligations of the Company contained herein or otherwise established with
respect to the Debentures;

               (b) to add further covenants, restrictions, conditions or
provisions for the protection of the holders of the Debentures of all or any
series as the Board of Directors and the Trustee shall consider to be for the
protection of the holders of Debentures of all or any series, and to make the
occurrence, or the occurrence and continuance, of a Default in any of such
additional covenants, restrictions, conditions or provisions a Default or an
Event of Default with respect to such series permitting the enforcement of all
or any of the several remedies provided in this Indenture as herein set forth;
provided, however, that in respect of any such additional covenant, restriction,
condition or provision such supplemental indenture may provide for a particular
period of grace after Default (which period may be shorter or longer than that
allowed in the case of other Defaults) or may provide for an immediate
enforcement upon such Default or may limit the remedies available to the Trustee
upon such Default or may limit the right of the holders of a majority in
aggregate principal amount of the Debentures of such series to waive such
Default;

               (c) to cure any ambiguity or to correct or supplement any
provision contained herein or in any supplemental indenture which may be
defective or inconsistent with any other provision contained herein or in any
supplemental indenture, or to make such other provisions in regard to matters or
questions arising under this Indenture as shall not be inconsistent with the
provisions of this Indenture and shall not materially adversely affect the
interests of the holders of the Debentures of any series;

               (d) to add to, change or eliminate any of the provisions of this
Indenture, provided that any such addition, change or elimination shall become
effective only when there is no Debenture Outstanding of any series created
prior to the execution of such supplemental indenture which is entitled to the
benefit of such provision;

               (e) to provide for the issuance under this Indenture of
Debentures in coupon form (including Debentures registrable as to principal
only) and to provide for exchangeability of such Debentures with the Debentures
issued hereunder in fully registered form and to make all appropriate changes
for such purposes;

                                       47
<PAGE>   55

               (f) to evidence and provide for the acceptance of appointment
hereunder by a successor trustee with respect to the Debentures of one or more
series and to add to or change any of the provisions of this Indenture as shall
be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, pursuant to the requirements of Sections
7.10 and 7.11;

               (g) to qualify or maintain qualification of this Indenture under
the Trust Indenture Act;

               (h) to establish the form or terms of Debentures of any series as
permitted by Section 2.01; or

               (i) to make any addition, change or elimination of any provision
of this Indenture that does not adversely affect the rights of any
Debentureholder in any material respect.

               The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, and to make any further
appropriate agreements and stipulations which may be therein contained, but the
Trustee shall not be obligated to, but may in its discretion, enter into any
such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

               Any supplemental indenture authorized by the provisions of this
Section may be executed by the Company and the Trustee without the consent of
the holders of any of the Debentures at the time Outstanding, notwithstanding
any of the provisions of Section 9.02.

         SECTION 9.02 With Consent of Debentureholders.

               With the consent (evidenced as provided in Section 8.01) of the
holders of not less than a majority in aggregate principal amount of the
Debentures of all series affected by such supplemental indenture or indentures
at the time Outstanding (acting as one class) (and, in the case of any series of
Debentures held as trust assets of a Trust and with respect to which a Security
Exchange has not theretofore occurred, such holders' obtaining such consent of
holders of the Preferred Securities and the Common Securities of such Trust as
may be required under the Declaration of Trust of such Trust), the Company and
the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto (which shall conform to the provisions of the
Trust Indenture Act as then in effect) for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental indenture or of modifying in any manner the
rights of the holders of the Debentures of such series under this Indenture;
provided, however, that no such supplemental indenture shall (i) extend the
fixed maturity of any Debentures of any series, or reduce the principal amount
thereof, or reduce the rate or extend the time of payment of interest thereon,
or reduce any premium payable upon the redemption thereof; (ii) reduce the
aforesaid percentage of Debentures, the holders of which are required to consent
to any such supplemental indenture; (iii) impair the right of a holder of
Debentures to receive payment of principal of and interest on such Debentures on
or after the due dates therefor or to institute suit for the enforcement of
payment thereof or with respect thereto; (iv) make any change in this proviso of
this Section

                                       48
<PAGE>   56

9.02; (v) change any obligation of the Company to pay Additional Amounts with
respect to any Debentures; or (vi) impair the right of a holder of Debentures to
convert or exchange such Debentures for another security, if such Debentures
shall be so convertible or exchangeable, without in each case the consent of the
holders of each Debenture (and, in the case of any series of Debentures held as
trust assets of a Trust and with respect to which a Security Exchange has not
theretofore occurred, such holders' obtaining such consent of the holders of the
Preferred Securities and the Common Securities of such Trust as may be required
under the Declaration of Trust of such Trust) then Outstanding and affected
thereby.

               Upon the request of the Company, and upon the filing with the
Trustee of evidence of the consent of Debentureholders (and, in the case of any
series of Debentures held as trust assets of a Trust and with respect to which a
Security Exchange has not theretofore occurred, such holders' obtaining such
consent of holders of the Preferred Securities and the Common Securities of such
Trust as may be required under the Declaration of Trust of such Trust) required
to consent thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplemental indenture.

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

               Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall transmit by mail, first class postage prepaid, a notice, setting
forth in general terms the substance of such supplemental indenture, to the
Debentureholders of all series affected thereby as their names and addresses
appear upon the Debenture Register. Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

         SECTION 9.03  Effect of Supplemental Indentures.

               Upon the execution of any supplemental indenture pursuant to the
provisions of this Article or of Section 10.01, this Indenture shall, with
respect to such series, be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Debentures of the series affected thereby shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

         SECTION 9.04  Debentures May Bear Notation of Changes By Supplemental
                       Indentures.

               Debentures of any series, affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture
pursuant to the provisions of this

                                       49
<PAGE>   57

Article or of Section 10.01, may bear a notation in form approved by the
Company, provided such form meets the requirements of any exchange upon which
such series may be listed or traded, as to any matter provided for in such
supplemental indenture. If the Company shall so determine, new Debentures of
that series so modified as to conform, in the opinion of the Board of Directors,
to any modification of this Indenture contained in any such supplemental
indenture may be prepared by the Company, authenticated by the Trustee and
delivered in exchange for the Debentures of that series then outstanding.

         SECTION 9.05  Opinion of Counsel.

               The Trustee, subject to the provisions of Sections 7.01 and 7.02,
may receive an Opinion of Counsel as conclusive evidence that any supplemental
indenture executed pursuant hereto complies with the requirements of this
Article IX.

all of its assets to any Person, unless:

               (1) either (a) the Company shall be the continuing corporation or
         (b) the Person formed by or surviving such consolidation or merger (if
         other than the Company), or to which such sale, lease, conveyance,
         transfer or other disposition shall be made (collectively, the
         "Successor"), is organized and existing under the laws of the United
         States, any political subdivision thereof or any State thereof or the
         District of Columbia and expressly assumes by supplemental indenture
         all of the obligations of the Company under this Indenture and the
         Debentures;

               (2) immediately after giving effect to such transaction, no
         Default or Event of Default shall have occurred and be continuing; and

               (3) the Company delivers to the Trustee an Officers' Certificate
         and an Opinion of Counsel, each stating that the transaction and such
         supplemental indenture comply with this Indenture.

         SECTION 10.02  Successor Corporation Substituted.

               Upon any consolidation or merger of the Company or any sale,
lease, conveyance, transfer or other disposition of all or substantially all of
the assets of the Company in accordance with Section 10.01, any Successor formed
by such consolidation or into or with which the Company is merged or to which
such sale, lease, conveyance, transfer or other disposition is made shall
succeed to, and be substituted for, and may exercise every right and power of
the Company under this Indenture and each series of Debentures with the same
effect as if such Successor had been named as the Company herein and the
predecessor Company, in the case of a

                                       50
<PAGE>   58

sale, conveyance, transfer or other disposition (other than a lease), shall be
released from all obligations under this Indenture and each series of
Debentures.

                                   ARTICLE XI

            SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS

         SECTION 11.01 Satisfaction and Discharge of Indenture.

               (a) The following provisions shall apply to the Debentures of

proper instruments acknowledging the same, if

               (1) with reference to this provision the Company has irrevocably
         deposited or caused to be irrevocably deposited with the Trustee as
         trust funds in trust, specifically pledged as security for, and
         dedicated solely to, the benefit of the holders of the Debentures of

         such deposit;

               (3) the Company has delivered to the Trustee a ruling received by
         the Company from the U.S. Internal Revenue Service which states that,
         or an Opinion of Counsel which states that, the holders of the
         Debentures of such series will not recognize income, gain or loss for
         United States federal income tax purposes as a result of such deposit,
         defeasance and discharge and will be subject to United States federal
         income tax on the same amount and in the same manner and at the same
         times, as would have been the case if such deposit, defeasance and
         discharge had not occurred;

               (4) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent provided for relating to the defeasance contemplated by this

               (5) no event or condition shall exist that, pursuant to the
         provisions of Section 14.02 or 14.03, would prevent the Company from
         making payments of the principal of, any premium or interest on or any
         Additional Amounts with respect to the Debentures of such series on the
         date of such deposit; and

               (6) the Company has delivered to the Trustee an Opinion of
         Counsel to the effect that after the passage of 91 days following the
         deposit, the trust funds will not be subject to the effect of any
         applicable bankruptcy, insolvency, reorganization or similar laws
         affecting creditors' rights generally.

                        of Debentures.

               Subject to Section 11.04, all moneys deposited with the Trustee

by it to the payment, either directly or through any paying agent (including the
Company acting as its own paying agent), to the holders of the particular
Debentures of such series for the payment or redemption of which such moneys
have been deposited with the Trustee, of all sums due and to become due thereon
for principal and interest; but such money need not be segregated from other
funds except to the extent required by law. Notwithstanding anything contained
herein to the contrary, all moneys in trust are not subject to Article XIV.

         SECTION 11.03  Repayment of Moneys Held by the Paying Agent.

               In connection with the satisfaction and discharge of this

Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys.

         SECTION 11.04  Repayment of Moneys Held by the Trustee.

agent for the payment of the principal of, premium, if any, interest and any
Additional Amounts on any Debenture of any series and not applied but remaining
unclaimed for two years after the date upon which such principal, premium, if
any, or interest and any Additional Amounts shall have become due and payable,
shall, upon the written request of the Company and unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law, be repaid to the Company by the Trustee for such series or such paying
agent, and a holder of the Debentures of such series shall, unless otherwise
required by mandatory provisions of applicable escheat or abandoned or unclaimed
property laws, thereafter look only to the Company for any payment which such
holder may be entitled to collect, and all liability of the Trustee or any
paying agent with respect to such moneys shall thereupon cease; provided,
however, that the Trustee or such paying agent, before being required to make
any such repayment with respect to moneys deposited with it for any payment
series, shall at the expense of the Company, mail by first-class mail to holders
of such Debentures at their addresses as they shall appear on the Debenture
Register, notice, that such moneys remain and that, after a date specified
therein, which shall not be less than 30 days from the date of such mailing or
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

         SECTION 11.05  Indemnification Relating to Governmental Obligations.

               The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the Governmental Obligations
deposited pursuant to Section 11.01 or the principal or interest received in
respect of such obligations.

         SECTION 11.06  Reinstatement.

               If the Trustee or any paying agent is unable to apply any money
or Government Obligations deposited with respect to Debentures of any series in
accordance with this Article XI by reason of any legal proceeding or by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the obligations of the
Company under this Indenture with respect to the Debentures of such series and
under the Debentures of such series shall be revived and reinstated as though no
deposit had occurred pursuant to this Article XI until such time as the Trustee
or such paying agent is permitted to apply all such money or Government
Obligations in accordance with this Article XI; provided, however, that if the
Company has made any payment of principal of, any premium or interest on or any
Additional Amounts with respect to any Debentures because of the reinstatement
of its obligations, the Company shall be subrogated to the rights of the holders
of such Debentures to receive such payment from the money or Government
Obligations held by the Trustee or such paying agent.

invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Indenture or of

         SECTION 13.11 Assignment.

<PAGE>   65

the event of any such assignment, the Company will remain jointly and severally

         SECTION 13.12  Holders of Preferred Securities as Third Party
                        Beneficiaries.

               The Company acknowledges that, prior to a Security Exchange with
respect to Debentures of any series held as trust assets of a Trust, if the
Property Trustee of such Trust fails to enforce its rights under this Indenture
as the holder of the Debentures of a series held as trust assets of such Trust,
any holder of the Preferred Securities of such Trust may, subject to Section
6.04 and Section 6.06 and in accordance with the provisions of the Declaration
of Trust of such Trust, institute legal proceedings directly against the Company
to enforce such Property Trustee's rights under this Indenture without first
instituting any legal proceedings against such Property Trustee or any other
Person; provided that, if an Event of Default has occurred and is continuing and
such event is attributed to the failure of the Company to pay principal of, any
premium or interest on or Additional Amounts with respect to the Debentures on
the date such amounts are otherwise payable (or in the case of redemption, on
the redemption date), then a holder of Preferred Securities of such Trust may
directly institute a proceeding for enforcement of payment to such holder of
such amounts on the Debentures having a principal amount equal to the aggregate
liquidation amount of the Preferred Securities of such holder (a "Holder Direct
Action") on or after the respective due date specified in the Debentures. In
connection with such Holder Direct Action, the Company shall be subrogated to
the rights of such holder of Preferred Securities to the extent of any payment
made by the Company to such holders of Preferred Securities in such Holder
Direct Action. Except as provided in the preceding sentences or Section 6.01(e),
the holders of Preferred Securities of such Trust shall not be able to exercise
directly any other remedy available to the holders of the Debentures.

         SECTION 13.13  Payment Currency.

               Except as otherwise specified for the Debentures of a series as
contemplated by Section 2.01 hereof, all payments due hereunder shall be made in
Dollars. To the fullest extent permitted by applicable law, the obligation of
the Company in respect of any amount due hereunder shall, notwithstanding any
payment in any other currency (whether pursuant to a judgment or otherwise), be
discharged only to the extent of the amount in Dollars that the party entitled
to receive such payment may, in accordance with normal banking procedures,
purchase with the sum paid in such other currency (after any premium and costs
of exchange) in the city of receipt on the Business Day immediately following
the day on which such party receives such payment. If the amount in Dollars that
may be so purchased for any reason falls short of the amount originally due, the
Company shall pay such additional amounts, in Dollars, as may be necessary to
compensate for the shortfall. Any obligation of the Company not discharged by
such additional payment shall, to the fullest extent permitted by applicable
law, be due as a separate and independent obligation and, until discharged as
provided herein, shall continue in full force and effect.

Indenture pursuant to Section 11.01.

                                  ARTICLE XIV

                           SUBORDINATION OF DEBENTURES

               (a) No payment shall be made by or on behalf of the Company on
account of the principal of, any premium or interest on or any Additional
Amounts with respect to the Debentures of any series or to acquire any of such
Debentures (including any repurchases of such Debentures pursuant to the
provisions thereof at the option of the holder of such Debentures) for cash or
property, or on account of any redemption provisions of such Debentures, in the
event of default in payment of any principal of, premium (if any) or interest on
any Senior Debt of the Company when the same becomes due and payable, whether at
maturity or at a date fixed for prepayment or by acceleration of maturity or
otherwise (a "Payment Default"), unless and until such Payment Default has been
cured or waived or otherwise has ceased to exist or such Senior Debt shall have
been discharged or paid in full.

               (b) In furtherance of the provisions of Section 14.01, in the
event that, notwithstanding the foregoing provisions of this Section 14.02, any
payment or distribution of assets of the Company shall be received by the
Trustee or the holders of Debentures of any series at a time when such payment
or distribution was prohibited by the provisions of this Section 14.02, then,
unless such payment or distribution is no longer prohibited by this Section
14.02, such payment or distribution (subject to the provisions of Section 14.07)
shall be received and held in trust by the Trustee or such holder or paying
agent for the benefit of the holders of Senior Debt of the Company, and shall be
paid or delivered by the Trustee or such holders or such paying agent, as the
case may be, to the holders of Senior Debt of the Company remaining unpaid or
unprovided for or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Debt of the Company may have been issued, ratably, according to the
aggregate amounts remaining unpaid on account of such Senior Debt of the Company
held or represented by each, for application to the payment of all Senior Debt
in full after giving effect to all concurrent payments and distributions to or
for the holders of such Senior Debt.

         SECTION 14.03  Debentures Subordinated to Prior Payment of All Senior
                        Debt on Dissolution, Liquidation or Reorganization.

               Upon any distribution of assets of the Company or upon any
dissolution, winding up, total or partial liquidation or reorganization of the
Company, whether voluntary or involuntary, in bankruptcy, insolvency,
receivership or similar proceeding or upon assignment for the benefit of
creditors:

               (a) the holders of all Senior Debt of the Company shall first be
entitled to receive payments in full before the holders of Debentures of any
series are entitled to receive any payment on account of the principal of, any
premium or interest on or any Additional Amounts with respect to such
Debentures;

               (b) any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to which the holders
of Debentures of any series or the Trustee on behalf of such holders would be
entitled, except for the provisions of this Article XIV, shall be paid by the
liquidating trustee or agent or other Person making such a payment or
distribution directly to the holders of such Senior Debt or their
representative, ratably according to the respective amounts of Senior Debt held
or represented by each, to the extent necessary to make payment in full of all
such Senior Debt remaining unpaid after giving effect to all concurrent payments
and distributions to the holders of such Senior Debt; and

               (c) 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, shall be received by the Trustee or
the holders of Debentures of any series or any paying agent (or, if the Company
or any Affiliate of the Company is acting as its own paying agent, money for
any such payment or distribution shall be segregated or held in trust) on
account of the principal of, any premium or interest on or any Additional
Amounts with respect to the Debentures of such series before all Senior Debt of
the Company is paid in full, such payment or distribution (subject to the
provisions of Section 14.07) shall be received and held in trust by the Trustee
or such holder or paying agent for the benefit of the holders of such Senior

                                       60
<PAGE>   68

Debt, or their respective representatives, ratably according to the respective
amounts of such Senior Debt held or represented by each, to the extent necessary
to make payment as provided herein of all such Senior Debt remaining unpaid
after giving effect to all concurrent payments and distributions and all
provisions therefor to or for the holders of such Senior Debt, but only to the
extent that as to any holder of such Senior Debt, as promptly as practical
following notice from the Trustee to the holders of such Senior Debt that such
prohibited payment has been received by the Trustee, holder(s) or paying agent
(or has been segregated as provided above), such holder (or a representative
therefor) notifies the Trustee of the amounts then due and owing on such Senior
Debt, if any, held by such holder and only the amounts specified in such notices
to the Trustee shall be paid to the holders of such Senior Debt.

         SECTION 14.04  Subrogation to Rights of Holders of Senior Debt.

               Subject to the payment in full of all Senior Debt of the Company
as provided herein, the holders of the Debentures shall be subrogated (to the
extent of the payments or distributions made to the holders of such Senior Debt
pursuant to the provisions of this Article) to the rights of the holders of such
Senior Debt to receive payments or distributions of assets of the Company
applicable to the Senior Debt until all amounts owing on the Debentures shall be
paid in full. For the purpose of such subrogation, no such payments or
distributions to the holders of such Senior Debt by the Company, or by or on
behalf of the holders of the Debentures by virtue of this Article XIV, which
otherwise would have been made to such holders shall, as between the Company and
such holders, be deemed to be payment by the Company or on account of such
Senior Debt, it being understood that the provisions of this Article XIV are and
are intended solely for the purpose of defining the relative rights of the
holders of the Debentures, on the one hand, and the holders of such Senior Debt,
on the other hand.

               If any payment or distribution to which the holders of the
Debentures would otherwise have been entitled but for the provisions of this
Article XIV shall have been applied, pursuant to the provisions of this Article
XIV, to the payment of amounts payable under Senior Debt of the Company, then
such holders shall be entitled to receive from the holders of such Senior Debt
any payments or distributions received by such holders of Senior Debt in excess
of the amount sufficient to pay all amounts payable under or in respect of such
Senior Debt in full.

         SECTION 14.05  Obligations of the Company Unconditional.

               Nothing contained in this Article XIV or elsewhere in this
Indenture or in the Debentures is intended to or shall impair, as between the
Company and the holders of the Debentures of any series, the obligation of the
Company, which is absolute and unconditional, to pay to such holders the
principal of, any premium and interest on or any Additional Amounts with respect
to the Debentures of such series 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 such holders and creditors of the Company other than the
holders of the Senior Debt, nor shall anything herein or therein prevent the
Trustee or any holder from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article XIV, of the holders of Senior Debt in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy. Notwithstanding anything to the contrary in this Article XIV or
elsewhere in this Indenture or in the Debentures,

                                       61
<PAGE>   69

upon any distribution of assets of the Company referred to in this Article XIV,
the Trustee, subject to the provisions of Sections 7.01 and 7.02, and the
holders of the Debentures 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 liquidating trustee or agent or other Person making any distribution to the
Trustee or to such holders for the purpose of ascertaining the Persons entitled
to participate in such distribution, the holders of the Senior Debt and other
Debt 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 XIV so long as such court has been apprised of the provisions of,
or the order, decree or certificate makes reference to, the provisions of this
Article XIV.

         SECTION 14.06  Trustee Entitled to Assume Payments Not Prohibited in
                        Absence of Notice.

               The Trustee shall not at any time be charged with knowledge of
the existence of any facts that would prohibit the making of any payment to or
by the Trustee unless and until a Responsible Officer of the Trustee or any
paying agent shall have received, no later than two Business Days prior to such
payment, written notice thereof from the Company or from one or more holders of
Senior Debt or from any representative therefor and, prior to the receipt of any
such written notice, the Trustee, subject to the provisions of Sections 7.01 and
7.02, shall be entitled in all respects conclusively to assume that no such fact
exists.

         SECTION 14.07  Application by Trustee of Amounts Deposited with It.

               Amounts deposited in trust with the Trustee pursuant to and in
accordance with Article XI shall be for the sole benefit of holders of the
Debentures of the series for the benefit of which such amounts were deposited,
and, to the extent allocated for the payment of Debentures of such series, shall
not be subject to the subordination provisions of this Article XIV. Otherwise,
any deposit of assets with the Trustee or the paying agent (whether or not in
trust) for the payment of principal of, any premium or interest on or any
Additional Amounts with respect to any Debentures shall be subject to the
provisions of Sections 14.01, 14.02, 14.03 and 14.04; provided that if prior to
two Business Days preceding the date on which by the terms of this Indenture any
such assets may become distributable for any purpose (including without
limitation, the payment of either principal of, any premium or interest on or
any Additional Amounts with respect to any Debenture), a Responsible Officer of
the Trustee or such paying agent shall not have received with respect to such
assets the written notice provided for in Section 14.06, then the Trustee or
such paying agent shall have full power and authority to receive such assets and
to apply the same to the purpose for which they were received, and shall not be
affected by any notice to the contrary that may be received by it on or after
such date; and provided further that nothing contained in this Article XIV shall
prevent the Company from making, or the Trustee from receiving or applying, any
payment in connection with the redemption of Debentures if the first publication
of notice of such redemption (whether by mail or otherwise in accordance with
this Indenture) has been made, and the Trustee has received such payment from
the Company, prior to the occurrence of any of the contingencies specified in
Section 14.02 or 14.03.

         SECTION 14.08  Subordination Rights Not Impaired by Acts or Omissions
                        of the Company or Holders of Senior Debt.

               No right of any present or future holders of any Senior Debt to
enforce subordination provisions contained in this Article XIV 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 of this Indenture,
regardless of any knowledge thereof that any such holder may have or be
otherwise charged with. The holders of Senior Debt may extend, renew, modify or
amend the terms of the Senior Debt or any security therefor and release, sell or
exchange such security and otherwise deal freely with the Company, all without
affecting the liabilities and obligations of the parties to this Indenture or
the holders of the Debentures.

         SECTION 14.09  Trustee to Effectuate Subordination of Debentures.

               Each holder of a Debenture by his acceptance thereof authorizes
and expressly directs the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination provisions contained in
this Article XIV and to protect the rights of the holders of the Debentures
pursuant to this Indenture, and appoints the Trustee his attorney-in-fact for
such purpose, including, in the event of any dissolution, winding up,
liquidation or reorganization of the Company (whether in bankruptcy, insolvency
or receivership proceedings or upon an assignment for the benefit of creditors
of the Company), the filing of a claim for the unpaid balance of his Debentures
in the form required in said proceedings and cause said claim to be approved. If
the Trustee does not file a proper claim or proof of debt in the form required
in such proceeding prior to 30 days before the expiration of the time to file
such claim or claims, then the holders of the Senior Debt or their
representative is hereby authorized to have the right to file and is hereby
authorized to file an appropriate claim for and on behalf of the holders of said
Debentures. Nothing herein contained shall be deemed to authorize the Trustee or
the holders of Senior Debt or their representative to authorize or consent to or
accept or adopt on behalf of any holder of Debentures any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any holder thereof, or to authorize the Trustee or the holders
of Senior Debt or their representative to vote in respect of the claim of any
holder of the Debentures in any such proceeding.

         SECTION 14.10  Right of Trustee to Hold Senior Debt.

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

         SECTION 14.11  Article XIV Not to Prevent Events of Default.

                  The failure to make a payment on account of principal of or
premium (if any) or interest or Additional Amounts on the Debentures by reason
of any provision of this Article XIV shall not be construed as preventing the
occurrence of a Default or an Event of Default under

                                       63
<PAGE>   71

Section 6.01 or in any way prevent the holders of the Debentures from exercising
any right hereunder other than the right to receive payment on the Debentures.

         SECTION 14.12  No Fiduciary Duty of Trustee to Holders of Senior Debt.

               The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders (other than
for its willful misconduct or negligence) if it shall in good faith mistakenly
pay over or distribute to the holders of the Debentures or the Company or any
other Person, cash, property or securities to which any holders of Senior Debt
shall be entitled by virtue of this Article XIV or otherwise. Nothing in this
Section 14.12 shall affect the obligation of any other such Person to hold such
payment for the benefit of, and to pay such payment over to, the holders of
Senior Debt or their representative.

         SECTION 14.13  Article Applicable to Paying Agent.

                  In case at any time any paying agent other than the Trustee
shall have been appointed by the Company and be then acting hereunder, the term
"Trustee" as used in this Article XIV shall in such case (unless the context
shall otherwise require) be construed as extending to and including such paying
agent within its meaning as fully for all intents and purposes as if such paying
agent were named in this Article in addition to or in place of the Trustee;
provided, however, that this Section 14.13 shall not apply to the Company or any
Affiliate of the Company if it or such Affiliate acts as paying agent.
