     If any of the terms of the series are established by action taken pursuant
to a Board Resolution of the Company, a copy of an appropriate record of such
action shall be 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 of the Company setting forth the terms of the series.

2.3  Date and Denomination of Debentures.

     The Debentures shall be issuable in such form and in such denominations as
shall be specified as contemplated by Section 2.2. In the absence of any such
specification with respect to the Debentures of any series, the Debentures of
such series shall be issuable as registered Debentures without coupons and in
the denominations of $25 and any multiple thereof. The Debentures shall be
numbered, lettered, or otherwise distinguished in such manner or in accordance
with such plans as the officers of the Company executing the same may determine
with the approval of the Trustee as evidenced by the execution and
authentication thereof.

     Every Debenture shall be dated the date of its authentication, shall be
payable on such dates and shall bear interest, if any, from the date set forth
on the face of the Debenture, in each case, as contemplated by Section 2.2. The
interest installment on any Debenture that 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. In the event that any Debenture of a
particular 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
3.2.

     Any interest on any Debenture that is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date for any Debenture 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 (a) or clause (b) below:

     (a) 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

                                       11
<Page>

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 Debenture holder 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 respective Predecessor Debentures) are registered on such
special record date and shall be no longer payable pursuant to the following
clause (b).

     (b) 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 on which such Debentures may be listed, and upon such
notice as may be required by such exchange, if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

     Unless otherwise set forth in a Board Resolution of the Company or one or
more indentures supplemental hereto establishing the terms of any series of
Debentures pursuant to Section 2.2 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 in which an Interest Payment Date established for such series pursuant to
Section 2.2 hereof shall occur, if such Interest Payment Date is the last 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 2.2
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, that were carried by such other Debenture.

2.4  EXECUTION AND AUTHENTICATIONS.

     (a) The Debentures shall be signed on behalf of the Company by its
President or one of its Vice Presidents or Chief Financial Officer or Treasurer,
attested by its Secretary or one of its Assistant Secretaries. Signatures may be
in the form of a manual or facsimile signature. The Company may use the
facsimile signature of any Person who shall have been a President or Vice
President thereof, or of any Person who shall have been a Secretary or Assistant
Secretary thereof, notwithstanding the fact that at the time the Debentures
shall be authenticated and delivered or disposed of such Person shall have
ceased to be the President or a Vice President, or the Secretary or an Assistant
Secretary, of the Company (and any such signature shall be binding on the
Company). The Debentures may contain such notations, legends or endorsements
required by law, stock exchange rule or usage. Each Debenture shall be dated the
date of its authentication by the Trustee.

                                       12
<Page>

     (b) A Debenture shall not be valid until authenticated manually by an
authorized signatory of the Trustee, or by an Authenticating Agent. Such
signature shall be conclusive evidence that the Debenture so authenticated has
been duly authenticated and delivered hereunder and that the holder is entitled
to the benefits of this Indenture.

     (c) 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 Trustee for authentication, together with a written order of the
Company for the authentication and delivery of such Debentures signed by its
President or any Vice President and its Chief Financial Officer or the Treasurer
or any Assistant Treasurer, and the Trustee in accordance with such written
order shall authenticate and deliver such Debentures.

     (d) 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 6.1) shall be
fully protected in relying upon:

          (i) a copy of any Board Resolution or Resolutions relating thereto
     and, if applicable, an appropriate record of any action taken pursuant to
     such resolution, in each case certified by the Secretary or an Assistant
     Secretary of the Company;

          (ii) an executed supplemental indenture, if any;

          (iii) an Officers' Certificate setting forth the form and terms of the
     Debentures as required pursuant to Section 2.1 and Section 2.2,
     respectively; and

          (iv) an Opinion of Counsel prepared in accordance with Section 12.7
     which shall also state:

               (1)  that the form of such Debentures has been established by or
                    pursuant to a resolution of the Board of Directors or by
                    supplemental indenture as permitted by Section 2.1 in
                    conformity with the provisions of this Indenture;

               (2)  that the terms of such Debentures have been established by
                    or pursuant to a resolution of the Board of Directors or by
                    supplemental indenture as permitted by Section 2.2 in
                    conformity with the provisions of this Indenture;

               (3)  that such Debentures, when authenticated and delivered by
                    the Trustee and issued by the Company in the manner and
                    subject to any conditions specified in such Opinion of
                    Counsel, will constitute valid and legally binding
                    obligations of the Company;

               (4)  that all laws and requirements in respect of the execution
                    and delivery by the Company of the Debentures have been
                    complied with and that authentication and delivery of the
                    Debentures by the Trustee will not violate the terms of the
                    Indenture; and

                                       13
<Page>

               (5)  such other matters as the Trustee may reasonably request.

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

2.5  REGISTRATION OF TRANSFER AND EXCHANGE.

     (a) Subject to Section 2.2(m), Debentures may be exchanged upon
presentation thereof at the office or agency of the Company designated for such
purpose in Wilmington, Delaware, or at the office of the Debenture Registrar,
for other Debentures of the same series in authorized denominations, upon
payment of a sum sufficient to cover any tax or other governmental charge in
relation thereto, all as provided in this Section 2.5. In respect of any
Debentures so surrendered for exchange, the Company shall execute, the Trustee

the Debenture or Debentures that the Debentureholder making the exchange shall
be entitled to receive, bearing numbers not contemporaneously outstanding.

to such reasonable regulations as the Debenture Registrar may prescribe, the
Company shall register the Debentures and the transfers of Debentures as in this
Article II PROVIDED and which at all reasonable times shall be open for
inspection by the Trustee. The registrar for the purpose of registering
Debentures and transfer of Debentures as herein provided shall initially be the
Trustee and thereafter as may be appointed by the Company as authorized by Board
Resolution (the "Debenture Registrar"). Upon surrender for transfer of any
Debenture at the office or agency of the Company designated for such purpose,
the Company shall execute, the Trustee shall authenticate and such office or
agency shall deliver in the name of the transferee or transferees a new
Debenture or Debentures of the same series for a like aggregate principal
amount. All Debentures presented or surrendered for exchange or registration of
transfer, as provided in this Section 2.5, shall be 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 such holder's duly
authorized attorney in writing.

     (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, 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 2.6 and Section 8.4 not involving any transfer.

     (d) The Company shall not be required (i) to issue, exchange or register
the transfer of any Debentures of the same series during a period beginning at
the opening of business 15 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; nor

                                       14
<Page>

(ii) to register the transfer of or exchange any Debentures or portions thereof
called for redemption.

     (e) Debentures may only be transferred, in whole or in part, in accordance
with the terms and conditions set forth in this Indenture. Any transfer or
purported transfer of any Debenture not made in accordance with this Indenture
shall be null and void.

2.6  TEMPORARY DEBENTURES.

     Pending the preparation of definitive Debentures, the Company may execute,
and the Trustee shall authenticate and deliver, temporary Debentures (printed,
lithographed, or typewritten). Such temporary Debentures shall be 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 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. Without unnecessary delay the Company
shall execute and shall furnish definitive Debentures and thereupon any or all
temporary Debentures may be surrendered in exchange therefor (without charge to
the holders), at the office or agency of the Company designated for the purpose
in Wilmington, Delaware, or such other location designated by the Company, and
the Trustee shall authenticate and such office or agency shall deliver in
exchange for such temporary Debentures an equal aggregate principal amount of
definitive Debentures, 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 shall be entitled
to the same benefits under this Indenture as definitive Debentures authenticated
and delivered hereunder.

2.7  MUTILATED, DESTROYED, LOST OR STOLEN DEBENTURES.

     (a) 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 the Company's request the Trustee (subject as
aforesaid) shall authenticate and deliver, a new Debenture 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, stolen or mutilated. In every case the applicant for a substituted
Debenture shall furnish to the Company and the Trustee such 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 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 deliver the same
upon the written request or authorization of the President or any Vice President
and the Chief Financial Officer or the Treasurer or any Assistant Treasurer 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
that 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

                                       15
<Page>

shall furnish to the Company and 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.

     (b) Every replacement Debenture issued pursuant to the provisions of this
Section 2.7 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 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.

2.8  CANCELLATION.

     All Debentures surrendered for the purpose of payment, redemption, exchange
or registration of transfer shall, if surrendered to the Company or any paying
agent, be delivered to the Trustee for cancellation, or, if surrendered to the
Trustee, shall be canceled 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 request of the Company at the time of such surrender, the
Trustee shall deliver to the Company canceled Debentures held by the Trustee. In
the absence of such request the Trustee may dispose of canceled Debentures in
accordance with its standard procedures and deliver a certificate of disposition
to the Company. 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.

2.9  BENEFIT OF INDENTURE.

     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 (and, with respect to the provisions of Article
XIII, the holders of Senior Indebtedness) any legal or equitable right, remedy
or claim under or in respect of this Indenture, or under any covenant, condition
or provision herein contained; all such covenants, conditions and provisions
being for the sole benefit of the parties hereto and of the holders of the
Debentures (and, with respect to the provisions of Article XIII, the holders of
Senior Indebtedness).

2.10 AUTHENTICATING AGENT.

     (a) So long as any of the Debentures remain Outstanding there may be an
Authenticating Agent for any or all such Debentures, which Authenticating Agent
the Trustee shall have the right to appoint. Said Authenticating Agent shall be
authorized to act on behalf of the Trustee to authenticate Debentures 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

                                       16
<Page>

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.
Each Authenticating Agent shall be acceptable to the Company and shall be a
corporation that 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 that 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.

     (b) 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.

2.11 GLOBAL DEBENTURES.

     (a) If the Company shall establish pursuant to Section 2.2 that the
Debentures of a particular series are to be issued as a Global Debenture, then
the Company shall execute and the Trustee shall, in accordance with Section 2.4,
authenticate and deliver, a Global Debenture that (i) shall represent, and shall
be denominated in an amount equal to the aggregate principal amount of, all of
the outstanding Debentures of such series, (ii) shall be registered in the name
of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instruction and (iv) shall bear a
legend substantially to the following effect: "Except as otherwise provided in
Section 2.11 of the Indenture, this Debenture may be transferred, in whole but
not in part, only to another nominee of the Depositary or to a successor
Depositary or to a nominee of such successor Depositary."

     (b) Notwithstanding the provisions of Section 2.5, the Global Debenture of
a series may be transferred, in whole but not in part and in the manner provided
in Section 2.5, 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 at any time the Depositary for a series of the 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, this Section 2.11 shall
no longer be applicable to the Debentures of such series and the Company will
execute, and subject to Section 2.5, the Trustee will authenticate and deliver,
the definitive Debentures of such series, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Debenture
of

                                       17
<Page>

such series in exchange for such Global Debenture. In addition, the Company may
at any time determine that the Debentures of any series shall no longer be
represented by a Global Debenture 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 2.5, the Trustee, upon receipt of
an Officers' Certificate evidencing such determination by the Company, will
authenticate and deliver the definitive Debentures of such series, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Debenture of such series in exchange for such Global
Debenture. Upon the exchange of the Global Debenture for such definitive
Debentures, in authorized denominations, the Global Debenture shall be cancelled
by the Trustee. Such definitive Debentures issued in exchange for the Global
Debenture pursuant to this Section 2.11(c) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. The Trustee shall deliver such definitive Debentures to the Depositary
for delivery to the Persons in whose names such definitive Debentures are so
registered.

2.12 CUSIP NUMBERS.

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

                                   ARTICLE III

                       PARTICULAR COVENANTS OF THE COMPANY

3.1  PAYMENT OF PRINCIPAL AND INTEREST.

     The Company covenants and agrees for the benefit of each series of
Debentures that it shall duly and punctually pay or cause to be paid the
principal of and interest on the Debentures at the time and place and in the
manner provided herein. Each such payment of the principal of and interest on
the Debentures shall relate only to the Debentures, shall not be combined with
any other payment of the principal of or interest on any other obligation of the
Company, and shall be clearly and unmistakably identified as pertaining to the
Debentures.

3.2  MAINTENANCE OF AGENCY.

     So long as any of the Debentures remain Outstanding, the Company shall
maintain, or shall cause to be maintained, an office or agency in Wilmington,
Delaware, and at such other location or locations as may be designated as
provided in this Section 3.2, where (i) Debentures of each series may be
presented for payment; (ii) Debentures of each 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 each
series and this Indenture may be given or served,

                                       18
<Page>

such designation to continue with respect to such office or agency until the
Company shall, by written notice signed by its President or an Executive Vice
President 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. In addition to any such office or agency, the Company may from time to
time designate one or more offices or agencies outside of Wilmington, Delaware,
where the Debentures of each series may be presented for registration or
transfer and for exchange in the manner provided herein, and the Company may
from time to time rescind such designation as the Company may deem desirable or
expedient; PROVIDED, HOWEVER, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain any such office or
agency in Wilmington, Delaware, for the purposes above mentioned. The Company
shall give the Trustee prompt written notice of any such designation or
rescission thereof.

3.3  PAYING AGENTS.

     (a) The Company shall be the initial paying agent. If the Company shall
appoint one or more paying agents for the Debentures of any series, other than
the Trustee, the Company shall cause each such paying agent 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 3.3:

          (i) that it shall hold all sums held by it as such agent for the
     payment of the principal of or interest on the Debentures of such series
     (whether such sums have been paid to it by the Company or by any other
     obligor of the Debentures of such series) in trust for the benefit of the
     Persons entitled thereto;

          (ii) that it shall give the Trustee notice of any failure by the
     Company (or by any other obligor on the Debentures of such series) to make
     any payment of the principal of or interest on the Debentures of such
     series when the same shall be due and payable;

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

          (iv) that it shall 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 the
Debentures of any series, it shall on or before each due date of the principal
of or interest on the Debentures of such series, set aside, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
such principal or interest so becoming due on the Debentures of such series
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and shall promptly notify the Trustee of such action, or any failure
(by it or any other obligor on the Debentures of such series) to take such
action. Whenever the Company shall have one or more paying agents for the
Debentures of such series, it shall, prior to each due date of the principal of
or interest on any Debentures of such series, deposit with the paying agent a
sum sufficient to

                                       19
<Page>

pay the principal or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal or interest, and (unless
such paying agent is the Trustee) the Company shall promptly notify the Trustee
of this action or failure so to act.

     (c) Notwithstanding anything in this Section 3.3 to the contrary, (i) the
agreement to hold sums in trust as provided in this Section 3.3 is subject to
the provisions of Section 10.3 and 10.4; and (ii) the Company may at any time,
for the purpose of obtaining the satisfaction and discharge with respect to one
or more or all of the series of Debentures hereunder or for any other purpose,
pay, or direct any paying agent to pay, to the Trustee all sums held in trust
for any such series 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 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.

3.4  APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE.

     The Company, whenever necessary to avoid or fill a vacancy in the office of
Trustee, shall appoint, in the manner provided in Section 6.11, a Trustee, so
that there shall at all times be a Trustee hereunder.

3.5  COMPLIANCE WITH CONSOLIDATION PROVISIONS.

     The Company shall not, while any of the Debentures remain outstanding,
consolidate with, or merge into, or merge into itself, or sell or convey all or
substantially all of its property to any other company unless the provisions of
Article IX hereof are complied with.

3.6  LIMITATION ON TRANSACTIONS.

     If Debentures of any series are issued to a Trust or a Trustee of a Trust
in connection with the issuance of Trust Securities by such Trust and (i) there
shall have occurred any event that would constitute an Event of Default; (ii)
the Company shall be in default with respect to any of its obligations under the
Preferred Securities Guarantee relating to such Trust; or (iii) the Company
shall have given notice of its election to defer payments of interest on such
Debentures by extending the interest payment period as provided in this
Indenture or any applicable supplement hereto and such period, or any extension
thereof, shall be continuing, then (a) the Company shall not declare or pay, and
shall not allow any of its Subsidiaries to declare or pay, any dividend on, make
any distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (A)
dividends or distributions in common stock of the Company or any Subsidiary of
the Company, or any declaration of a non-cash dividend in connection with the
implementation of a shareholder rights plan, or the issuance of stock under any
such plan in the future, or the redemption or repurchase of any such rights
pursuant thereto, (B) purchases of common stock of the Company related to the
rights under any benefit plans for its directors, officers or employees, (C) as
a result of a reclassification of its capital stock into another class of its
capital stock, or (D) payments of dividends or distributions to the Company);
and (b) the Company shall not make, and shall not allow any of its Subsidiaries
to make, any payment of interest, principal or premium, if any, or repay,
repurchase or redeem any debt securities issued by the Company which rank PARI
PASSU with or junior to the Debentures of such series or make any

                                       20
<Page>

guarantee payments with respect to any guarantee by the Company of the debt
securities of any subsidiary of the Company if such guarantee ranks PARI PASSU
with or junior in interest to the Debentures of such series; PROVIDED, HOWEVER,
that notwithstanding the foregoing the Company may make payments pursuant to its
obligations under the Preferred Securities Guarantee relating to such Trust; and
(c) the Company shall not redeem, purchase or acquire less than all of the
outstanding Debentures of such series or any of the Preferred Securities
relating to such Trust.

3.7  COVENANTS AS TO THE TRUSTS.

     In the event a series of Debentures is issued to a Trust or a trustee of
such Trust in connection with the issuance of Trust Securities by such Trust,
for so long as such Trust Securities remain outstanding, the Company shall (i)
maintain 100% direct or indirect ownership of the Common Securities of such
Trust; PROVIDED, HOWEVER, that any permitted successor of the Company under this
Indenture may succeed to the Company's ownership of such Common Securities; (ii)
not voluntarily terminate, wind up or liquidate such Trust, except upon prior
approval of the Federal Reserve if then so required under applicable capital
guidelines, policies or regulations of the Federal Reserve and use its
reasonable efforts to cause such Trust (a) to remain a business trust (and to
avoid involuntary termination, winding up or liquidation), except in connection
with a distribution of the Debentures of such series, the redemption of all of
the Trust Securities of such Trust or certain mergers, consolidations or
amalgamations, each as permitted by the Trust Agreement of such Trust; and (b)
to otherwise continue not to be treated as an association taxable as a
corporation or partnership for United States federal income tax purposes; (iii)
use its reasonable efforts to cause each holder of Trust Securities of such
Trust to be treated as owning an undivided beneficial interest in the Debentures
of such series; and (iv) the Company, and any successor to the Company, shall
use best efforts to maintain the eligibility of such Preferred Securities for
quotation or listing on any national securities exchange or other organization
on which such Preferred Securities are then quoted or listed (including, if
applicable, The Nasdaq National Market) and shall use best efforts to keep such
Preferred Securities so quoted or listed for so long as such Preferred
Securities remain outstanding. In connection with the distribution of Debentures
that have been issued to a Trust in connection with the issuance of Trust
Securities by such Trust to the holders of the Preferred Securities issued by
such Trust upon a Dissolution Event, the Company shall use its best efforts to
list such Debentures on The Nasdaq National Market or on such exchange or other
organization as such Preferred Securities are then listed or quoted. For so long
as any Debentures remain outstanding, the Company shall fulfill all reporting
and filing obligations under the Exchange Act, as applicable to companies having
a class of securities registered under Section 12(b) or 12(g) thereunder.

3.8  WAIVER OF USURY, STAY OR EXTENSION LAWS.

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

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

        REMEDIES OF THE TRUSTEE AND DEBENTUREHOLDERS ON EVENT OF DEFAULT

5.1  EVENTS OF DEFAULT.

     (a) Unless otherwise provided with respect to a series of Debentures in an
indenture supplemental hereto providing for the creation of that series, each of
the following events of default shall constitute an Event of Default with
respect to Debentures of such series, as shall any other events as may be
established with respect to Debentures of that series as contemplated by Section
2.2 (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of an
administrative or governmental body):

          (i) the Company defaults in the payment of any installment of interest
     upon 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

                                       23
<Page>

     any particular series of Debentures established as contemplated in this
     Indenture shall not constitute a default in the payment of interest for
     this purpose;

          (ii) the Company defaults in the payment of the principal 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 or otherwise;

          (iii) the Company fails to observe or perform any other of its
     covenants or agreements with respect to any of the Debentures of that
     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
     Debentures of that series at the time Outstanding;

          (iv) the Company pursuant to or within the meaning of any Bankruptcy
     Law (i) commences a voluntary case; (ii) consents to the entry of an order
     for relief against it in an involuntary case; (iii) consents to the
     appointment of a Custodian of it or for all or substantially all of its
     property; or (iv) makes a general assignment for the benefit of its
     creditors; or

          (v) a court of competent jurisdiction enters an order under any
     Bankruptcy Law that (i) is for relief against the Company in an involuntary
     case; (ii) appoints a Custodian of the Company for all or substantially all
     of its property; or (iii) orders the liquidation of the Company, and the
     order or decree remains unstayed and in effect for 90 days.

     (b) In each and every such case referred to in paragraph (i) through (v) of
this Section 5.1(a), unless the principal of all the Debentures with respect to
which an Event of Default has occurred shall have already become due and
payable, either the Trustee or the holders of not less than 25% in aggregate
principal amount of the Debentures of such series then Outstanding hereunder, 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 such series
to be due and payable immediately, and upon any such declaration the same shall
become and shall be immediately due and payable, notwithstanding anything
contained in this Indenture or in the Debentures of such series.

     (c) At any time after the principal of the Debentures of such 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 holders of a majority in aggregate principal amount of the
Debentures of such series then Outstanding hereunder, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if: (i) the Company has paid or deposited with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Debentures
of such series and the principal of any and all Debentures of such series that
shall have become due otherwise than by acceleration (with interest upon such
principal, and, to the extent that such payment is enforceable under applicable
law, upon overdue installments of interest, at the rate per annum expressed in
the

                                       24
<Page>

Debentures of such series to the date of such payment or deposit) and the amount
payable to the Trustee under Section 6.7; and (ii) any and all Events of Default
under this Indenture, other than the nonpayment of principal on Debentures that
shall not have become due by their terms, shall have been remedied or waived as
provided in Section 5.6. No such rescission and annulment shall extend to or
shall affect any subsequent default or impair any right consequent thereon.

     (d) In case the Trustee shall have proceeded to enforce any right with
respect to Debentures of any 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.

5.2  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

     (a) The Company covenants that (1) in case it shall default in the payment
of any installment of interest on any of the Debentures of any series, and such
default shall have continued for a period of 30 days; or (2) in case it shall
default in the payment of the principal of any of the Debentures of any series
when the same shall have become due and payable, whether upon maturity of the
Debentures of such series or upon redemption or upon declaration or otherwise,
then, upon demand of the Trustee, the Company shall pay to the Trustee, for the
benefit of the holders of the Debentures of such series, the whole amount that
then shall have become due and payable on all such Debentures of such series for
principal or interest, or both, as the case may be, with interest upon the
overdue principal and (to the extent that payment of such interest is
enforceable under applicable law and, if the Debentures of such series are held
by the Trust or a trustee of the Trust, without duplication of any other amounts
paid by the Trust or trustee in respect thereof) upon overdue installments of
interest at the rate per annum expressed in the Debentures of such 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 6.7.

     (b) If the Company shall fail to pay such amounts set forth in Section
5.2(a) forthwith 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 such Debentures and collect the moneys adjudged or decreed to
be payable in the manner provided by law out of the property of the Company or
other obligor upon such Debentures, wherever situated.

     (c) In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affecting the Company, any Trust, or the creditors or property of the Company or
any Trust, the Trustee shall have 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

                                       25
<Page>

Trustee and of the holders of the Debentures (or, with respect to any of the
foregoing events affecting a Trust, the Debentures that have been issued to such
Trust) allowed for the entire amount due and payable by the Company under this
Indenture at the date of institution of such proceedings and for any additional
amount that may become due and payable by the Company 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 6.7; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the holders of the
Debentures of each 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
6.7.

     (d) All rights of action and of asserting claims under this Indenture, or
under any of the terms established with respect to any of the Debentures, 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 6.7, be
for the ratable benefit of the holders of such Debentures. 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. Nothing contained herein 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 any of the Debentures 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.

5.3  APPLICATION OF MONEYS COLLECTED.

     Any moneys or other assets collected by the Trustee pursuant to this
Article V with respect to any of the Debentures shall be applied in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys or other assets on account of principal or interest,
upon presentation of such Debentures in respect of which moneys have been
collected, and notation 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 6.7;

     SECOND: To the payment of all Senior Indebtedness of the Company if and to
     the extent required by Article XIII; and

     THIRD: To the payment of the amounts then due and unpaid upon such
     Debentures for principal and interest, in respect of which or for the
     benefit of which such money has been

                                       26
<Page>

     collected, ratably, without preference or priority of any kind, according
     to the amounts due and payable on such Debentures for principal and
     interest, respectively.

5.4  LIMITATION ON SUITS.

     (a) Except as set forth in this Indenture, 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 (i) such holder
previously shall have given to the Trustee written notice of an Event of Default
and of the continuance thereof with respect to the Debentures of such series
specifying such Event of Default, as hereinbefore provided; (ii) 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; (iii) such
holder or holders shall have offered to the Trustee such reasonable indemnity as
it may require against the costs, expenses and liabilities to be incurred
therein or thereby; (iv) the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity, shall have failed to institute any such
action, suit or proceeding; and (v) during such 60 day period, the holders of a
majority in principal amount of the Debentures of such series do not give the
Trustee a direction inconsistent with the request.

     (b) Notwithstanding anything contained herein to the contrary or any other
provisions of this Indenture, the right of any holder of any Debentures to
receive payment of the principal of and interest on such Debentures, 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 and
by accepting a Debenture hereunder it is expressly understood, intended and
covenanted by the taker and holder of every Debenture of any series with every
other such taker and holder and the Trustee, that no one or more holders of
Debentures of any series shall have any right in any manner whatsoever by virtue
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of the holders of any other 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 the
applicable series. For the protection and enforcement of the provisions of this
Section 5.4, each and every Debentureholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

5.5  RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER.

     (a) Except as otherwise provided in Section 2.7(b), all powers and remedies
given by this Article V to the Trustee or to the Debentureholders shall, to the
extent permitted by law, be deemed cumulative and not exclusive of any other
powers and remedies available to the Trustee or the holders of the Debentures,
by judicial proceedings or otherwise, to enforce the performance or observance
of the covenants and agreements contained in this Indenture or otherwise
established with respect to the Debentures of any series.

                                       27
<Page>

     (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 on acquiescence
therein; and, subject to the provisions of Section 5.4, every power and remedy
given by this Article V or by law to the Trustee or the Debentureholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Debentureholders.

5.6  CONTROL BY DEBENTUREHOLDERS.

     The holders of a majority in aggregate principal amount of the Debentures
of any or all series affected (voting as one class) at the time Outstanding,
determined in accordance with Section 7.4, shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee;
PROVIDED, HOWEVER, that such direction shall not be in conflict with any rule of
law or with this Indenture. Subject to the provisions of Section 6.1, 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
any series of Debentures at the time Outstanding affected thereby, determined in
accordance with Section 7.4, may on behalf of the holders of all of such
Debentures waive any past default in the performance of any of the covenants
contained herein and its consequences, except (i) a default in the payment of
the principal of, or interest on, any of such Debentures 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 interest and principal has been deposited with the Trustee (in
accordance with Section 5.1(c)); (ii) a default in the covenants contained in
Section 3.7 with respect to a Trust to which such Debentures have been issued;
or (iii) in respect of a covenant or provision hereof which cannot be modified
or amended without the consent of the holder of each Outstanding Debenture
affected; PROVIDED, HOWEVER, that if the Debentures are held by a Trust or a
trustee of a Trust, such waiver or modification to such waiver shall not be
effective until the holders of a majority in liquidation preference of Trust
Securities of the applicable Trust shall have consented to such waiver or
modification to such waiver; PROVIDED FURTHER, that if the consent of the holder
of each Outstanding Debenture that has been issued to such Trust in connection
with issuance of Trust Securities by such Trust is required, such waiver shall
not be effective until each holder of the Trust Securities of such Trust shall
have consented to such waiver. Upon any such waiver, the default covered thereby
shall be deemed to be cured for all purposes of this Indenture and the Company,
the Trustee and the holders of the Debentures of each such series (or of all the
Debentures, as the case may be) 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.

5.7  UNDERTAKING TO PAY COSTS.

     All parties to this Indenture agree, and each holder of any Debentures by
such holder's 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

                                       28
<Page>

reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section 5.7 shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Debentureholder, or group of Debentureholders of any series
holding more than 10% in aggregate principal amount of the Outstanding
Debentures of that series, or to any suit instituted by any Debentureholder for
the enforcement of the payment of the principal of or interest on any
Debentures, on or after the respective due dates expressed in any such Debenture
or established pursuant to this Indenture.

5.8  DIRECT ACTION; RIGHT OF SET-OFF.

     In the event that an Event of Default has occurred and is continuing and
such event is attributable to the failure of the Company to pay interest on or
principal of the Debentures of any series on an Interest Payment Date or
Maturity Date, as applicable, then a holder of Preferred Securities issued by a
Trust to which such Debentures have been issued may institute a legal proceeding
directly against the Company for enforcement of payment to such holder of the
principal of or interest on such Debentures having a principal amount equal to
the aggregate Liquidation Amount of such Preferred Securities of such holders (a
"Direct Action"). In connection with such Direct Action, the Company will have a
right of set-off under this Indenture with respect to such series of Debentures
to the extent of any payment actually made by the Company to such holder of the
Preferred Securities with respect to such Direct Action.

                                   ARTICLE VI

                             CONCERNING THE TRUSTEE

6.1  CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

     (a) With respect to the holders of any series of Debentures issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to Debentures of that series and after the curing of all Events of
Default that may have occurred with respect to Debentures of that series, shall
undertake to perform with respect to such Debentures 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 has occurred that has not been cured or waived, the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in its 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:

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

               (1)  the duties and obligations of the Trustee shall be
                    determined solely by the express provisions of this
                    Indenture, and the Trustee shall

                                       29
<Page>

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

               (2)  in the absence of bad faith on the part of the Trustee, the
                    Trustee may conclusively rely, as to the truth of the
                    statements and the correctness of the opinions expressed
                    therein, upon any certificates or opinions furnished to the
                    Trustee and conforming to the requirements of this
                    Indenture; but in the case of any such certificates or
                    opinions that 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;

          (ii) 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;

          (iii) 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 Debentureholders pursuant to Section 5.6 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; and

          (iv) 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 reasonably assured to it.

6.2  NOTICE OF DEFAULTS.

     Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to any series of
Debentures, the Trustee shall transmit by mail to all holders of such
Debentures, as their names and addresses appear in the Debenture Register,
notice of such default, unless such default shall have been cured or waived;
PROVIDED, HOWEVER, that, except in the case default in the payment of the
principal or interest (including any Additional Interest) on such Debentures,
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 the
directors and/or Responsible Officers of the Trustee determines in good faith
that the withholding of such notice is in the interests of the holders of such
Debentures; and PROVIDED, FURTHER, that in the case of any default of the
character specified in Section 5.1(a)(iii), no such notice to holders of such
Debentures need be sent until at least 30 days after the occurrence thereof. For
the purposes of this Section 6.2, the term "default" means any event which is,
or after notice or lapse of time or both, would become, an Event of Default with
respect to a series of Debentures.

6.3  CERTAIN RIGHTS OF TRUSTEE.

     Except as otherwise provided in Section 6.1:

     (a) The Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, consent, order, 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 its President or any Vice President and by the
Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer
thereof (unless other evidence in respect thereof is specifically prescribed
herein);

     (c) The Trustee shall not be deemed to have knowledge of a default or an
Event of Default, other than an Event of Default specified in Section 5.1(a)(i)
or (ii), unless and until it receives written notification of such Event of
Default from the Company or by holders of at least 25% of the aggregate
principal amount of the series of Debentures to which the Event of Default
relates at the time Outstanding;

     (d) The Trustee may consult with counsel 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;

     (e) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the Debentureholders, pursuant to the provisions of this Indenture,
unless such Debentureholders shall have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that may be
incurred therein or thereby; nothing contained herein shall, however, relieve
the Trustee of the obligation, upon the occurrence of an Event of Default (that
has not been cured or waived) to exercise with respect to the Debentures to
which the Event of Default relates such of the rights and powers vested in it by
this Indenture, and to use the same degree of care and skill in its exercise, as
a prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs;

     (f) 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;

     (g) 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 applicable series of the
Outstanding Debentures (determined as provided in Section 7.4); 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

                                       31
<Page>

Indenture, the Trustee may require reasonable indemnity 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; and

     (h) 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.

6.4  TRUSTEE NOT RESPONSIBLE FOR RECITALS, ETC.

     (a) The Recitals contained herein and in 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 for the use or application of any moneys
received by any paying agent other than the Trustee.

6.5  MAY HOLD DEBENTURES.

     The Trustee or any paying agent or registrar for the Debentures, in its
individual or any other capacity, may become the owner or pledgee of Debentures
with the same rights it would have if it were not Trustee, paying agent or
Debenture Registrar.

6.6  MONEYS HELD IN TRUST.

     Subject to the provisions of Section 10.5, 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 with the Company to pay thereon.

6.7  COMPENSATION AND REIMBURSEMENT.

     (a) The Company covenants and agrees to pay to the Trustee, and the Trustee
shall be entitled to, such reasonable compensation (which shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust), as the Company and the Trustee may from time to time agree in writing,
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, except as otherwise expressly provided herein, the Company
shall pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of

                                       32
<Page>

all Persons not regularly in its employ) except any such expense, disbursement
or advance as may arise from its negligence, bad faith or willful misconduct.
The Company also covenants to indemnify the Trustee (and its officers, agents,
directors and employees) for, and to hold it harmless against, any loss,
liability or expense incurred without negligence, bad faith or willful
misconduct on the part of the Trustee and arising out of or in connection with
the acceptance or administration of this trust, including the costs and expenses
of defending itself against any claim of liability in the premises.

     (b) The obligations of the Company under this Section 6.7 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.

6.8  RELIANCE ON OFFICERS' CERTIFICATE.

     Except as otherwise provided in Section 6.1, 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, bad faith or willful misconduct 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, bad
faith or willful misconduct 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.

6.9  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.

6.10 CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

     There shall at all times be a Trustee with respect to the Debentures issued
hereunder which shall at all times be a corporation organized and doing business
under the laws of the United States of America or any state or territory thereof
or of the District of Columbia, or a corporation or other Person permitted to
act as trustee by the Commission, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000, and subject to supervision or examination by federal, state,
territorial, or District of Columbia authority. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 6.10, 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 Company, serve as Trustee. In case at any time the Trustee shall cease to be
eligible in accordance

                                       33
<Page>

with the provisions of this Section 6.10, the Trustee shall resign immediately
in the manner and with the effect specified in Section 6.11.

6.11 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     (a) The Trustee or any successor hereafter appointed, may at any time
resign by giving written notice thereof to the Company and by transmitting
notice of resignation by mail, first class postage prepaid, to the
Debentureholders, 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 one or more series of Debentures by
written instrument, in duplicate, executed by order of the Board of Directors,
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 30 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 such
Debentures, or any Debentureholder who has been a bona fide holder of a
Debenture or Debentures of the applicable series for at least six months may,
subject to the provisions of Sections 6.9 and 6.10, 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 one of the following shall occur:

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

          (ii) the Trustee shall cease to be eligible in accordance with the
     provisions of Section 6.10 and shall fail to resign after written request
     therefor by the Company or by any such Debentureholder; or

          (iii) the Trustee shall become incapable of acting, or shall be
     adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy
     proceeding, or a receiver of the Trustee or of its property shall be
     appointed or consented to, 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 of any series and appoint a successor trustee or trustees 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 or trustees, or, subject to the provisions of Sections 6.9
and 6.10, unless the Trustee's duty to resign is stayed as provided herein, any
Debentureholder who has been a bona fide holder of a Debenture or Debentures of
the applicable series for at least six months may, on behalf of that holder and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor trustee or
trustees. Such court may thereupon after such notice, if

                                       34
<Page>

any, as it may deem proper and prescribe, remove the Trustee and appoint a
successor trustee or trustees.

     (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 by so notifying the Trustee and the Company
and may appoint a successor Trustee with respect to such series with the consent
of the Company.

     (d) Any resignation or removal of the Trustee and appointment of a
successor trustee or trustees pursuant to any of the provisions of this Section
6.11 shall become effective upon acceptance of appointment by the successor
trustee or trustees as provided in Section 6.12.

     (e) Any successor trustee appointed pursuant to this Section 6.11 may be
appointed with respect to the Debentures of the applicable series, and at any
time there shall be only one Trustee with respect to the Debentures of any one
series.

6.12 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     (a) In case of the appointment hereunder of a successor trustee, every
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) If a successor trustee is appointed 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 any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring trustee with respect to the
Debentures of any series as to which the predecessor trustee is not retiring
shall continue to be vested in the predecessor trustee, and shall add to or
change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trustee hereunder by more than one
trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such trustees co-trustees of the same trust and that
each such trustee shall be trustee of a trust or trusts hereunder separate and
apart from any trust or trusts hereunder administered by any other such trustee.

     (c) Upon request of any 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, powers and trusts referred to in
paragraph (a) of this Section 6.12.

     (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 VI.

                                       35
<Page>

     (e) Upon acceptance of appointment by a successor trustee as provided in
this Section 6.12, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage prepaid, to the Debentureholders
of the applicable series, as their names and addresses appear upon the Debenture
Register. If the Company fails to transmit such notice within ten days after
acceptance of appointment by the successor trustee, the successor trustee shall
cause such notice to be transmitted at the expense of the Company.

6.13 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be
qualified under the provisions of Section 6.9 and eligible under the provisions
of Section 6.10, 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 of any series shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Debentures of such series so authenticated
with the same effect as if such successor Trustee had itself authenticated such
Debentures.

6.14 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.

                                   ARTICLE VII

                         CONCERNING THE DEBENTUREHOLDERS

7.1  EVIDENCE OF ACTION BY HOLDERS.

     (a) Whenever in this Indenture it is provided that the holders of a
majority or specified percentage in aggregate principal amount of any or all
series of Debentures 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 have joined therein may be evidenced by any
instrument or any number of instruments of similar tenor executed by such
holders of Debentures in Person or by agent or proxy appointed in writing.

     (b) 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,

                                       36
<Page>

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 such series 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 such 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 such series shall be
computed as of the record date; PROVIDED, HOWEVER, 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.

7.2  PROOF OF EXECUTION BY DEBENTUREHOLDERS.

     Subject to the provisions of Section 6.1, proof of the execution of any
instrument by a Debentureholder (such proof shall not require notarization) or
such Debentureholder's 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 7.2 as it shall deem necessary.

7.3  WHO MAY BE DEEMED OWNERS.

     Prior to the due presentment for registration of transfer of any Debenture,
the Company, the Trustee, any paying agent, any Authenticating Agent and any
Debenture Registrar may deem and treat the Person in whose name such Debenture
shall be registered upon the books of the Company 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 and interest on such Debenture and for all other purposes; and
neither the Company nor the Trustee nor any paying agent nor any Authenticating
Agent nor any Debenture Registrar shall be affected by any notice to the
contrary.

7.4  CERTAIN DEBENTURES OWNED BY COMPANY DISREGARDED.

     In determining whether the holders of the requisite aggregate principal
amount of Debentures have concurred in any direction, consent or waiver under
this Indenture, the Debentures of the applicable series that are owned by the
Company or any other obligor on such Debentures or by any Person directly or
indirectly controlling or controlled by or under common control with the Company
or any other obligor on such series of Debentures shall be disregarded and
deemed not to be Outstanding for the purpose of any such determination, except
(i) that for the purpose of determining whether the Trustee shall be protected
in relying on any such direction, consent or waiver, only such Debentures that
the Trustee actually knows are so owned shall be so disregarded;

                                       37
<Page>

and (ii) for purposes of this Section 7.4, the Trust shall be deemed not to be
controlled by the Company. The Debentures so owned that have been pledged in
good faith may be regarded as Outstanding for the purposes of this Section 7.4,
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.

7.5  ACTIONS BINDING ON FUTURE DEBENTUREHOLDERS.

     At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 7.1, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Debentures of any
series specified in this Indenture in connection with such action, any holder of
a Debenture that 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 7.2, 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 any series
specified in this Indenture in connection with such action shall be conclusively
binding upon the Company, the Trustee and the holders of all such Debentures.

                                  ARTICLE VIII

                             SUPPLEMENTAL INDENTURES

8.1  SUPPLEMENTAL INDENTURES WITHOUT THE 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 cure any ambiguity, defect, or inconsistency herein, or in any
series of Debentures;

     (b) to comply with Article VII;

     (c) to provide for uncertificated Debentures in addition to or in place of
certificated Debentures;

of all or any series of Debentures (and if such covenants are for the benefit of
less than all series of Debentures, stating that such covenants are expressly
being included for the benefit of such series) or to surrender any right or
power herein conferred upon the Company;

                                       38
<Page>

     (e) to add to, delete from, or revise the conditions, limitations, and
restrictions on the authorized amount, terms, or purposes of issue,
authentication, and delivery of any series of Debentures, only as herein set
forth;

     (f) to make any change that does not adversely affect the rights of any
Debentureholder in any material respect;

     (g) to provide for the issuance of and establish the form and terms and
conditions of any series of Debentures as permitted by Sections 2.1 and 2.2, to
establish the form of any certifications required to be furnished pursuant to
the terms of this Indenture or any series of Debentures, or to add to the rights
of the holders of any series of Debentures;

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

     (i) to evidence a consolidation or merger involving the Company as
permitted under Section 9.1.

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 that may be therein contained, but the Trustee shall not be
obligated to enter into any such supplemental indenture that affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
Any supplemental indenture authorized by the provisions of this Section 8.1 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 8.2.

8.2  SUPPLEMENTAL INDENTURES WITH CONSENT OF DEBENTUREHOLDERS.

     With the consent (evidenced as provided in Section 7.1) of any series
(except as may otherwise be provided by the terms of any supplemental indenture
establishing such series in accordance with Section 2.2 hereof) of the holders
of not less than a majority in aggregate principal amount of the Debentures at
the time Outstanding of all series affected by such supplemental indenture
(voting as a class), the Company, when authorized by Board Resolutions, 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 not
covered by Section 8.1 the rights of the holders of the Debentures of each
series so affected under this Indenture; PROVIDED, HOWEVER, that no such
supplemental indenture shall without the consent of the holders of each
Debenture then Outstanding and affected thereby, (i) extend the fixed maturity
of any Debentures of any series (except as may otherwise be provided by the
terms of any supplemental indenture establishing such series in accordance with
Section 2.2 hereof), or reduce the rate or extend the time of payment of
interest thereon (except as may otherwise be provided by the terms of any
supplemental indenture establishing such series in accordance with Section 2.2
hereof), or reduce the principal amount thereof without the consent of the
holder of each Debenture so affected; or (ii) reduce the aforesaid percentage of
Debentures, the holders of which are required

                                       39
<Page>

to consent to any such supplemental indenture; PROVIDED FURTHER, that if the
applicable Debentures are held by a Trust or a trustee of such Trust, such
supplemental indenture shall not be effective until the holders of a majority in
liquidation preference of Trust Securities of the related Trust shall have
consented to such supplemental indenture; PROVIDED FURTHER, that if the consent
of the holder of each Outstanding Debenture of any series is required, such
supplemental indenture shall not be effective until each holder of the Trust
Securities of the related Trust shall have consented to such supplemental
indenture. It shall not be necessary for the consent of the Debentureholders
affected thereby under this Section 8.2 to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

8.3  EFFECT OF SUPPLEMENTAL INDENTURES.

     Upon the execution of any supplemental indenture pursuant to the provisions
of this Article VIII, this Indenture shall be and be deemed to be modified and
amended in accordance therewith and the respective rights, limitations of
rights, obligations, duties and immunities under this Indenture of the Trustee,
the Company and the holders of Debentures of all 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.

8.4  DEBENTURES AFFECTED BY SUPPLEMENTAL INDENTURES.

     Debentures affected by a supplemental indenture, authenticated and
delivered after the execution of such supplemental indenture pursuant to the
provisions of this Article VIII, may bear a notation in form approved by the
Company, provided such form meets the requirements of any exchange or automated
quotation system upon which the series of Debentures affected thereby may be
listed or quoted, as to any matter provided for in such supplemental indenture.
If the Company shall so determine, new Debentures so modified as to conform, in
the opinion of the Board of Directors of the Company, 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 then Outstanding.

8.5  EXECUTION OF SUPPLEMENTAL INDENTURES.

     (a) Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Debentureholders 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. The Trustee, subject to the
provisions of Section 6.1, may receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article VIII
is authorized or permitted by, and conforms to, the terms of this Article VIII
and that it is proper for the Trustee under the provisions of this Article VIII
to join in the execution thereof.

                                       40
<Page>

     (b) Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section 8.5, 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.

                                   ARTICLE IX

                              SUCCESSOR CORPORATION

9.1  COMPANY MAY CONSOLIDATE, ETC.

     Nothing contained in this Indenture or in any of the Debentures shall
prevent any consolidation or merger of the Company with or into any other
corporation or corporations (whether or not affiliated with the Company, as the
case may be), or successive consolidations or mergers in which the Company, as
the case may be, or its successor or successors shall be a party or parties, or
shall prevent any sale, conveyance, transfer or other disposition of the
property of the Company, as the case may be, or its successor or successors as
an entirety, or substantially as an entirety, to any other corporation (whether
or not affiliated with the Company, as the case may be, or its successor or
successors) authorized to acquire and operate the same; PROVIDED, HOWEVER, the
Company hereby covenants and agrees that, (i) upon any such consolidation,
merger, sale, conveyance, transfer or other disposition, the due and punctual
payment, in the case of the Company, of the principal of and interest on all of
the Debentures, according to their tenor and the due and punctual performance
and observance of all the covenants and conditions of this Indenture to be kept
or performed by the Company as the case may be, shall be expressly assumed, by
supplemental indenture (which shall conform to the provisions of the Trust
Indenture Act, as then in effect) satisfactory in form to the Trustee executed
and delivered to the Trustee by the entity formed by such consolidation, or into
which the Company, as the case may be, shall have been merged, or by the entity
which shall have acquired such property, and the ultimate parent entity of such
successor entity expressly assumes the obligations of the Company under each of
the related Preferred Securities Guarantees, to the extent any Preferred
Securities are then Outstanding; (ii) in case the Company consolidates with or
merges into another Person or conveys or transfers its properties and assets
substantially as an entirety to any Person, the successor Person is organized
under the laws of the United States or any state or the District of Columbia;
and (iii) immediately after giving effect thereto, no Event of Default, and no
event which, after notice or lapse of time or both, would become an Event of
Default, shall have occurred and be continuing.

9.2  SUCCESSOR CORPORATION SUBSTITUTED.

     (a) In case of any such consolidation, merger, sale, conveyance, transfer
or other disposition and upon the assumption by the successor corporation, by
supplemental indenture, executed and delivered to the Trustee and satisfactory
in form to the Trustee, of, in the case of the Company, the due and punctual
payment of the principal of and interest on all of the Debentures Outstanding
and the due and punctual performance of all of the covenants and conditions of
this Indenture to be performed by the Company, as the case may be, such
successor

                                       41
<Page>

corporation shall succeed to and be substituted for the Company, with the same
effect as if it had been named as the Company herein, and thereupon the
predecessor corporation shall be relieved of all obligations and covenants under
this Indenture and the Debentures.

     (b) In case of any such consolidation, merger, sale, conveyance, transfer
or other disposition such changes in phraseology and form (but not in substance)
may be made in the Debentures thereafter to be issued as may be appropriate.

     (c) Nothing contained in this Indenture or in any of the Debentures shall
prevent the Company from merging into itself or acquiring by purchase or

with the provisions of this Article IX.

                           SATISFACTION AND DISCHARGE

10.1 SATISFACTION AND DISCHARGE OF INDENTURE.

     If at any time: (a) the Company shall have delivered to the Trustee for
cancellation all Debentures theretofore authenticated (other than any Debentures
that shall have been destroyed, lost or stolen and that shall have been replaced
or paid as provided in Section 2.7) and all Debentures for whose payment money
or Governmental Obligations have theretofore been deposited in trust or
segregated and held in trust by the Company (and thereupon repaid to the Company
or discharged from such trust, as provided in Section 10.5); or (b) all such
Debentures not theretofore delivered to the Trustee for cancellation shall have
become due and payable, or are by their terms to become due and payable within
one year or are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, and the
Company shall deposit or cause to be deposited with the Trustee as trust funds
the entire amount in moneys or Governmental Obligations sufficient or a
combination thereof, sufficient in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay at maturity or upon redemption all Debentures
not theretofore delivered to the Trustee for cancellation, including principal
and interest due or to become due to such date of maturity or date fixed for
redemption, as the case may be, and if the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company; then this Indenture shall
thereupon cease to be of further effect except for the provisions of Sections
2.3, 2.5, 2.7, 3.1, 3.2, 3.3, 6.6, 6.7 and 6.10, that shall survive until the
date of maturity or redemption date, as the case may be, and Sections 6.7 and
10.5, that shall survive to such date and thereafter, and the Trustee, on demand
of the Company and at the cost and expense of the Company, shall execute proper
instruments acknowledging satisfaction of and discharging this Indenture.

10.2 DISCHARGE OF OBLIGATIONS.

     If at any time all Debentures of any series not heretofore delivered to the
Trustee for cancellation or that have not become due and payable as described in
Section 10.1 shall have been paid by the Company by depositing irrevocably with
the Trustee as trust funds moneys or an amount of Governmental Obligations
sufficient in the opinion of a nationally recognized certified public accounting
firm to pay at maturity or upon redemption all Debentures of such series not
theretofore delivered to the Trustee for cancellation, including principal and
interest due or to become due to such date of maturity or date fixed for
redemption, as the case may be, and if the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company, then after the date such
moneys or Governmental Obligations, as the case may be, are deposited with the
Trustee, the obligations of the Company under this Indenture shall cease to be
of further effect except for the provisions of Sections 2.3, 2.5, 2.7, 3.1, 3.2,
3.3, 6.6, 6.7 and 10.5 hereof that shall survive until such Debentures shall

     All monies or Governmental Obligations deposited with the Trustee pursuant
to Sections 10.1 or 10.2 shall be held in trust and shall be available for

Company acting as its own paying agent), to the holders of the applicable
Debentures for the payment or redemption of which such moneys or Governmental
Obligations have been deposited with the Trustee.

10.4 PAYMENT OF MONIES HELD BY PAYING AGENTS.

     In connection with the satisfaction and discharge of this Indenture, all
moneys or Governmental Obligations then held by any paying agent under the
provisions of this Indenture shall, upon demand of the Company, be paid to the
Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys or Governmental Obligations.

10.5 REPAYMENT TO COMPANY.

     Any monies or Governmental Obligations deposited with any paying agent or
the Trustee, or then held by the Company in trust, for payment of principal of
or interest on any series of Debentures that are not applied but remain
unclaimed by the holders of such Debentures for at least two years after the
date upon which the principal of or interest on such Debentures shall have
respectively become due and payable, shall be repaid to the Company, as the case
may be, on December 31 of each year or (if then held by the Company) shall be
discharged from such trust; and thereupon the paying agent and the Trustee shall
be released from all further liability with respect to such moneys or
Governmental Obligations, and the holder of any of such Debentures entitled to
receive such payment shall thereafter, as an unsecured general creditor, look
only to the Company for the payment thereof.

issued hereunder are solely corporate obligations, and that no such personal

any predecessor or successor corporation, or any of them, because of the

<Page>

and thereupon such power so surrendered shall terminate both as to the Company,

construed in accordance with the laws of said State.

12.6 TREATMENT OF DEBENTURES AS DEBT.

     It is intended that the Debentures shall be treated as indebtedness and not
as equity for federal income tax purposes. The provisions of this Indenture
shall be interpreted to further this intention.

12.7 COMPLIANCE CERTIFICATES AND OPINIONS.

     (a) Upon any application or demand by the Company to the Trustee to take

                                       45
<Page>

been complied with; PROVIDED, HOWEVER, that each such certificate shall comply

12.8 PAYMENTS ON BUSINESS DAYS.

     In any case where the date of maturity of interest or principal of any
Debenture or the date of redemption of any Debenture shall not be a Business
Day, then payment of interest or principal may be made on the next succeeding
Business Day with the same force and effect as if made on the nominal date of
maturity or redemption, and no interest shall accrue for the period after such
nominal date, except that if such next succeeding Business Day falls in the next
succeeding calendar year, then such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

12.9 CONFLICT WITH TRUST INDENTURE ACT.

     If and to the extent that any provision of this Indenture limits, qualifies
or conflicts with the duties imposed by Sections 310 to 317, inclusive, of the
Trust Indenture Act, such imposed duties shall control.

12.10 COUNTERPARTS.

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

12.11 SEVERABILITY.

     In case any one or more of the provisions contained in this Indenture or in
any series of Debentures shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Indenture or of such Debentures,
but this Indenture and such Debentures shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or therein.

12.12 ASSIGNMENT.

     The Company shall have the right at all times to assign any of its
respective rights or obligations under this Indenture to a direct or indirect
wholly owned Subsidiary of the Company, provided that, in the event of any such
assignment, the Company shall remain liable for all such obligations. Subject to
the foregoing, this Indenture is binding upon and inures to the benefit of the
parties thereto and their respective successors and assigns. This Indenture may
not otherwise be assigned by the parties thereto.

12.13 ACKNOWLEDGMENT OF RIGHTS.

     The Company acknowledges that, with respect to any series of Debentures
held by a Trust or a trustee of such Trust, if the applicable Property Trustee
fails to enforce its rights under this Indenture as the holder of such
Debentures held as the assets of such Trust, any holder of the applicable
Preferred Securities may institute legal proceedings directly against the
Company to enforce such Property Trustee's rights under this Indenture without
first instituting any legal

                                       46
<Page>

proceedings against such Property Trustee or any other person or entity.
Notwithstanding the foregoing, if an Event of Default with respect to a series
of Debentures has occurred and is continuing and such event is attributable to
the failure of the Company to pay interest or principal on such Debentures on
the date such interest or principal is otherwise payable (or in the case of
redemption, on the redemption date), the Company acknowledges that a holder of
the applicable Preferred Securities may directly institute a proceeding for
enforcement of payment to such holder of the principal of or interest on such
Debentures having a principal amount equal to the aggregate liquidation amount
of such Preferred Securities of such holder on or after the respective due date
specified in such Debentures.

                                  ARTICLE XIII

                           SUBORDINATION OF DEBENTURES

13.1 AGREEMENT TO SUBORDINATE.

     The Company covenants and agrees, and each holder of Debentures issued
hereunder by such holder's acceptance thereof likewise covenants and agrees,
that all Debentures shall be issued subject to the provisions of this Article
XIII; and each holder of a Debenture, whether upon original issue or upon
transfer or assignment thereof, accepts and agrees to be bound by such
provisions. The payment by the Company of the principal of and interest on all
Debentures issued hereunder shall, to the extent and in the manner hereinafter
set forth, be subordinated and junior in right of payment to the prior payment
in full of all Senior Debt, Subordinated Debt and Additional Senior Obligations
(collectively, "Senior Indebtedness") to the extent provided herein, whether
outstanding at the date of this Indenture or thereafter incurred. No provision
of this Article XIII shall prevent the occurrence of any default or Event of
Default hereunder.

13.2 DEFAULT ON SENIOR DEBT, SUBORDINATED DEBT OR ADDITIONAL SENIOR OBLIGATIONS.

     In the event and during the continuation of any default by the Company in
the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness of the Company, or in the event that the maturity of any
Senior Indebtedness of the Company has been accelerated because of a default,
then, in either case, no payment shall be made by the Company with respect to
the principal (including redemption payments) of or interest on any series of
Debentures. In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee when such payment is prohibited by the preceding
sentence of this Section 13.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

13.3 LIQUIDATION; DISSOLUTION; BANKRUPTCY.

     (a) Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Senior Indebtedness
of the Company shall first be paid in full, or payment thereof provided for in
money in accordance with its terms, before any payment is made by the Company on
account of the principal or interest on any series of Debentures; and upon any
such dissolution or winding-up or liquidation or reorganization, any payment by
the Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the holders of any series of
Debentures or the Trustee would be entitled to receive from the Company, except
for the provisions of this Article XIII, shall be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the holders of the applicable
Debentures or by the Trustee under this Indenture if received by them or it,
directly to the holders of Senior Indebtedness of the Company (pro rata to such
holders on the basis of the respective amounts of Senior Indebtedness held by
such holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Indebtedness may have been issued,
as their respective interests may appear, to the extent necessary to pay such
Senior Indebtedness in full, in money or money's worth, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Indebtedness, before any payment or distribution is made to the holders of any
series of Debentures or to the Trustee.

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

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

                                       48
<Page>

or the merger of the Company into, another corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation upon the
terms and conditions provided for in Article IX shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 13.3 if such other corporation shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article IX.
Nothing in Section 13.2 or in this Section 13.3 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.7.

13.4 SUBROGATION.

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

     (b) Nothing contained in this Article XIII or elsewhere in this Indenture
or in the Debentures is intended to or shall impair, as between the Company, its
creditors (other than the holders of Senior Indebtedness of the Company), and
the holders of each series of Debentures, the obligation of the Company, which
is absolute and unconditional, to pay to the holders of each series of
Debentures the principal of and interest on such Debentures as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the holders of each series of Debentures
and creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness of the Company, as the case may be, nor shall anything
herein or therein prevent the Trustee or the holder of any Debenture from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article XIII of the
holders of such Senior Indebtedness in respect of cash, property or securities
of the Company, as the case may be, received upon the exercise of any such
remedy.

     (c) Upon any payment or distribution of assets of the Company referred to
in this Article XIII, the Trustee, subject to the provisions of Article VI, and
the holders of the Debentures shall be entitled to conclusively rely upon any
order or decree made by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidation trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to

                                       49
<Page>

the holders of the Debentures, for the purposes of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, as the case may be, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article XIII.

13.5 TRUSTEE TO EFFECTUATE SUBORDINATION.

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

13.6 NOTICE BY THE COMPANY.

     (a) The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of any series of
Debentures pursuant to the provisions of this Article XIII. Notwithstanding the
provisions of this Article XIII or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment of monies to or by the Trustee in
respect of any series of Debentures pursuant to the provisions of this Article
XIII, unless and until a Responsible Officer of the Trustee shall have received
written notice thereof from the Company or a holder or holders of Senior
Indebtedness or from any trustee therefor; and before the receipt of any such
written notice, the Trustee, subject to the provisions of Section 6.1, shall be
entitled in all respects to assume that no such facts exist; PROVIDED, HOWEVER,
that if the Trustee shall not have received the notice provided for in this
Section 13.6 at least two Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of or interest on any Debenture), then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such money and to apply the same to the
purposes for which they were received, and shall not be affected by any notice
to the contrary that may be received by it within two Business Days prior to
such date.

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

13.7 RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

     (a) The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XIII in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder. The Trustee's right to compensation and reimbursement
of expenses as set forth in Section 6.7 shall not be subject to the
subordination provisions of the Article XIII.

     (b) With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article XIII, and no implied
covenants or obligations with respect to the holders of such Senior Indebtedness
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and,
subject to the provisions of Section 6.1, the Trustee shall not be liable to any
holder of such Senior Indebtedness if it shall pay over or deliver to holders of
Debentures, the Company or any other Person money or assets to which any holder
of such Senior Indebtedness shall be entitled by virtue of this Article XIII or
otherwise.

13.8 SUBORDINATION MAY NOT BE IMPAIRED.

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

     (b) Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from time
to time, without the consent of or notice to the Trustee or the holders of any
series of Debentures, without incurring responsibility to the holders of any
series of Debentures and without impairing or releasing the subordination
provided in this Article XIII or the obligations hereunder of the holders of any
