of the Debt Securities shall cease to be such officer before the Debt Securities
so signed shall have been authenticated and delivered by the Trustee or the
Authenticating Agent, or disposed of by the Company, such Debt Securities
nevertheless may be authenticated and delivered or disposed of as though the
Person who signed such Debt Securities had not ceased to be such officer of the

AND IS NOT SECURED.

         SECTION 2.06. Mutilated, Destroyed, Lost or Stolen Debt Securities.

                  In case any Debt Security shall become mutilated or be
destroyed, lost or stolen, the Company shall execute, and upon its written
request the Trustee shall authenticate and deliver, a new Debt Security bearing
a number not contemporaneously outstanding, in exchange and substitution for the
mutilated Debt Security, or in lieu of and in substitution for the Debt Security
so destroyed, lost or stolen. In every case the applicant for a substituted Debt
Security 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
such Debt Security and of the ownership thereof.

                  The Trustee may authenticate any such substituted Debt
Security and deliver the same upon the written request or authorization of any
officer of the Company. Upon the issuance of any substituted Debt Security, 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 connected therewith. In case any Debt Security which has matured or is
about to mature or has been called for redemption in full shall become mutilated
or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Debt Security, pay or authorize the payment of the same (without
surrender thereof except in the case of a mutilated Debt Security) if the
applicant for such payment 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 case of destruction, loss or theft, evidence satisfactory to the Company
and to the Trustee of the destruction, loss or theft of such Security and of the
ownership thereof.

                  Every substituted Debt Security issued pursuant to the
provisions of this Section 2.06 by virtue of the fact that any such Debt
Security is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Debt
Security shall be found at any time, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Debt
Securities duly issued hereunder. All Debt Securities shall be held and owned
upon the express condition that, to the extent permitted by applicable law, the
foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Debt Securities and shall preclude any and
all other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender.

         SECTION 2.07. Temporary Debt Securities.

                  Pending the preparation of definitive Debt Securities, the
Company may execute and the Trustee shall authenticate and make available for
delivery temporary Debt Securities that are typed, printed or lithographed.
Temporary Debt Securities shall be issuable in any authorized denomination, and
substantially in the form of the definitive Debt Securities but with such
omissions, insertions and variations as may be appropriate for temporary Debt
Securities, all as

                                      -13-

<PAGE>

may be determined by the Company. Every such temporary Debt Security shall be
executed by the Company and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Debt Securities. Without unreasonable delay, the Company will
execute and deliver to the Trustee or the Authenticating Agent definitive Debt
Securities and thereupon any or all temporary Debt Securities may be surrendered
in exchange therefor, at the Principal Office of the Trustee or at any office or
agency maintained by the Company for such purpose as provided in Section 3.02,
and the Trustee or the Authenticating Agent shall authenticate and make
available for delivery in exchange for such temporary Debt Securities a like
aggregate principal amount of such definitive Debt Securities. Such exchange
shall be made by the Company at its own expense and without any charge therefor
except that in case of any such exchange involving a registration of transfer
the Company may require payment of a sum sufficient to cover any tax, fee or
other governmental charge that may be imposed in relation thereto. Until so
exchanged, the temporary Debt Securities shall in all respects be entitled to
the same benefits under this Indenture as definitive Debt Securities
authenticated and delivered hereunder.

         SECTION 2.08. Payment of Interest.

                  Each Debt Security will bear interest at the then applicable
Interest Rate from and including each Interest Payment Date or, in the case of
the first interest period, the original date of issuance of such Debt Security
to, but excluding, the next succeeding Interest Payment Date or, in the case of
the last interest period, the Redemption Date, Special Redemption Date or
Maturity Date, as applicable, on the principal thereof, on any overdue principal
and (to the extent that payment of such interest is enforceable under applicable
law) on Deferred Interest and on any overdue installment of interest (including
Defaulted Interest), payable (subject to the provisions of Article XII) on each
Interest Payment Date commencing on January 7, 2004, 2003. Interest and any
Deferred Interest on any Debt Security that is payable, and is punctually paid
or duly provided for by the Company, on any Interest Payment Date shall be paid
to the Person in whose name said Debt Security (or one or more Predecessor
Securities) is registered at the close of business on the regular record date
for such interest installment, except that interest and any Deferred Interest
payable on the Maturity Date shall be paid to the Person to whom principal is
paid. In the event that any Debt Security 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 Debt Security will be paid upon presentation and surrender of
such Debt Security.

                  Any interest on any Debt Security, other than Deferred
Interest, that is payable, but is not punctually paid or duly provided for by
the Company, on any Interest Payment Date (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 to the Persons in whose names such Debt
Securities (or their respective Predecessor Securities) are registered at the
close of business on a special record date for the payment of such Defaulted
Interest, which shall be fixed in the following manner: the Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid
on each such Debt Security and the date of the proposed payment, and at the same
time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements reasonably

                                      -14-

<PAGE>

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 fifteen nor less than ten days
prior to the date of the proposed payment and not less than ten 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 Securityholder at his or her address as it
appears in the Debt Security Register, not less than ten 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 Debt
Securities (or their respective Predecessor Securities) are registered on such
special record date and thereafter the Company shall have no further payment
obligation in respect of the Defaulted Interest.

                  Any interest scheduled to become payable on an Interest
Payment Date occurring during an Extension Period shall not be Defaulted
Interest and shall be payable on such other date as may be specified in the
terms of such Debt Securities.

                  The term "regular record date" as used in this Section shall
mean the fifteenth day prior to an Interest Payment Date whether or not such
date is a Business Day.

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

         SECTION 2.09. Cancellation of Debt Securities Paid, etc.

                  All Debt Securities surrendered for the purpose of payment,
redemption, exchange or registration of transfer, shall, if surrendered to the
Company or any Paying Agent, be surrendered to the Trustee and promptly canceled
by it, or, if surrendered to the Trustee or any Authenticating Agent, shall be
promptly canceled by it, and no Debt Securities shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Indenture. All
Debt Securities canceled by any Authenticating Agent shall be delivered to the
Trustee. The Trustee shall destroy all canceled Debt Securities unless the
Company otherwise directs the Trustee in writing, in which case the Trustee
shall dispose of such Debt Securities as directed by the Company. If the Company
shall acquire any of the Debt Securities, however, such acquisition shall not
operate as a redemption or satisfaction of the indebtedness represented by such
Debt Securities unless and until the same are surrendered to the Trustee for
cancellation.

         SECTION 2.10. Computation of Interest.

                  (a) The amount of interest payable for any interest period
will be computed on the basis of a 360-day year and the actual number of days
elapsed in the relevant interest period; provided, however, that upon the
occurrence of a Special Event Redemption pursuant to Section

                                      -15-

<PAGE>

10.02 the amounts payable pursuant to this Indenture shall be calculated as set
forth in the definition of Special Redemption Price.

                  (b) LIBOR shall be determined by the Calculation Agent in
accordance with the following provisions:

                           (1) On the second LIBOR Business Day (provided, that
                  on such day commercial banks are open for business (including
                  dealings in foreign currency deposits) in London (a "LIBOR
                  Banking Day"), and otherwise the next preceding LIBOR Business
                  Day that is also a LIBOR Banking Day) prior to January 15,
                  April 15, July 15 and October 15 (except, with respect to the
                  first interest payment period, on December 16, 2003), (each
                  such day, a "LIBOR Determination Date"), LIBOR shall equal the
                  rate, as obtained by the Calculation Agent for three-month
                  U.S. Dollar deposits in Europe, which appears on Telerate Page
                  3750 (as defined in the International Swaps and Derivatives
                  Association, Inc. 1991 Interest Rate and Currency Exchange
                  Definitions) or such other page as may replace such Telerate
                  Page 3750, as of 11:00 a.m. (London time) on such LIBOR
                  Determination Date, as reported by Bloomberg Financial Markets
                  Commodities News. "LIBOR Business Day" means any day that is
                  not a Saturday, Sunday or other day on which commercial
                  banking institutions in New York, New York or Wilmington,
                  Delaware are authorized or obligated by law or executive order
                  to be closed. If such rate is superseded on Telerate Page 3750
                  by a corrected rate before 12:00 noon (London time) on the
                  same LIBOR Determination Date, the corrected rate as so
                  substituted will be the applicable LIBOR for that LIBOR
                  Determination Date.

                           (2) If, on any LIBOR Determination Date, such rate
                  does not appear on Telerate Page 3750 as reported by Bloomberg
                  Financial Markets Commodities News or such other page as may
                  replace such Telerate Page 3750, the Calculation Agent shall
                  determine the arithmetic mean of the offered quotations of the
                  Reference Banks (as defined below) to leading banks in the
                  London Interbank market for three-month U.S. Dollar deposits
                  in Europe (in an amount determined by the Calculation Agent)
                  by reference to requests for quotations as of approximately
                  11:00 a.m. (London time) on the LIBOR Determination Date made
                  by the Calculation Agent to the Reference Banks. If, on any
                  LIBOR Determination Date, at least two of the Reference Banks
                  provide such quotations, LIBOR shall equal the arithmetic mean
                  of such quotations. If, on any LIBOR Determination Date, only
                  one or none of the Reference Banks provide such a quotation,
                  LIBOR shall be deemed to be the arithmetic mean of the offered
                  quotations that at least two leading banks in the City of New
                  York (as selected by the Calculation Agent) are quoting on the
                  relevant LIBOR Determination Date for three-month U.S. Dollar
                  deposits in Europe at approximately 11:00 a.m. (London time)
                  (in an amount determined by the Calculation Agent). As used
                  herein, "Reference Banks" means four major banks in the London
                  Interbank market selected by the Calculation Agent.

                                      -16-

<PAGE>

                           (3) If the Calculation Agent is required but is
                  unable to determine a rate in accordance with at least one of
                  the procedures provided above, LIBOR shall be LIBOR in effect
                  on the previous LIBOR Determination Date (whether or not LIBOR
                  for such period was in fact determined on such LIBOR
                  Determination Date).

                  (c) All percentages resulting from any calculations on the
Debt Securities will be rounded, if necessary, to the nearest one
hundred-thousandth of a percentage point, with five one-millionths of a
percentage point rounded upward (e.g., 9.876545% (or .09876545) being rounded to
9.87655% (or .0987655)), and all dollar amounts used in or resulting from such
calculation will be rounded to the nearest cent (with one-half cent being
rounded upward).

                  (d) On each LIBOR Determination Date, the Calculation Agent
shall notify, in writing, the Company and the Paying Agent of the applicable
Interest Rate in effect for the related Interest Payment Date. The Calculation
Agent shall, upon the request of the holder of any Debt Securities, provide the
Interest Rate then in effect. All calculations made by the Calculation Agent in
the absence of manifest error shall be conclusive for all purposes and binding
on the Company and the Holders of the Debt Securities. The Paying Agent shall be
entitled to rely on information received from the Calculation Agent or the
Company as to the Interest Rate. The Company shall, from time to time, provide
any necessary information to the Paying Agent relating to any original issue
discount and interest on the Debt Securities that is included in any payment and
reportable for taxable income calculation purposes.

         SECTION 2.11. Extension of Interest Payment Period.

                  So long as no Event of Default has occurred and is continuing,
the Company shall have the right, from time to time and without causing an Event
of Default, to defer payments of interest on the Debt Securities by extending
the interest payment period on the Debt Securities at any time and from time to
time during the term of the Debt Securities, for up to twenty consecutive
quarterly periods (each such extended interest payment period, an "Extension
Period"), during which Extension Period no interest shall be due and payable
(except any Additional Interest that may be due and payable). No Extension
Period may end on a date other than an Interest Payment Date. During any
Extension Period, interest will continue to accrue on the Debt Securities, and
interest on such accrued interest (such accrued interest and interest thereon
referred to herein as "Deferred Interest") will accrue at an annual rate equal
to the Interest Rate in effect for such Extension Period, compounded quarterly
from the date such Deferred Interest would have been payable were it not for the
Extension Period, to the extent permitted by law. No interest or Deferred
Interest shall be due and payable during an Extension Period, except at the end
thereof. At the end of any such Extension Period the Company shall pay all
Deferred Interest then accrued and unpaid on the Debt Securities; provided,
however, that no Extension Period may extend beyond the Maturity Date; and
provided further, however, that during any such Extension Period, the Company
shall be subject to the restrictions set forth in Section 3.08 of this
Indenture. Prior to the termination of any Extension Period, the Company may
further extend such period, provided, that such period together with all such
previous and further consecutive extensions thereof shall not exceed twenty
consecutive quarterly periods, or extend beyond the Maturity Date. Upon the
termination of any Extension Period and upon the payment of all Deferred
Interest, the Company may commence a new Extension Period, subject

                                      -17-

<PAGE>

to the foregoing requirements. The Company must give the Trustee notice of its
election to begin such Extension Period ("Notice") at least one Business Day
prior to the earlier of (i) the next succeeding date on which interest on the
Debt Securities would have been payable except for the election to begin such
Extension Period or (ii) the date such interest is payable, but in any event not
later than the related regular record date. The Notice shall describe, in
reasonable detail, why the company has elected to begin an Extension Period. The
Notice shall acknowledge and affirm the Company's understanding that it is
prohibited from issuing dividends and other distributions during the Extension
Period. Upon receipt of the Notice, the Initial Purchaser or Initial Purchaser,
as applicable, has the right, at its sole discretion, to disclose the name of
the Company, the fact that the Company has elected to begin an Extension Period
and other information that the Initial Purchaser, or Initial Purchaser, as
applicable, at is sole discretion, deems relevant to the company's election to
begin an Extension Period. The Trustee shall give notice of the Company's
election to begin a new Extension Period to the Securityholders.

         SECTION 2.12. CUSIP Numbers.

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

         SECTION 2.13. Global Debentures.

                  (a) Upon the election of the holder of Outstanding Debentures,
which election need not be in writing, the Debentures owned by such holder shall
be issued in the form of one or more Global Debentures registered in the name of
the Depositary or its nominee. Each Global Debenture issued under this Indenture
shall be registered in the name of the Depositary designated by the Company for
such Global Debenture or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Debenture shall
constitute a single Debenture for all purposes of this Indenture.

                  (b) Notwithstanding any other provision in this Indenture, no
Global Debenture may be exchanged in whole or in part for Debentures registered,
and no transfer of a Global Debenture in whole or in part may be registered, in
the name of any Person other than the Depositary for such Global Debenture or a
nominee thereof unless (i) such Depositary advises the Trustee and the Company
in writing that such Depositary is no longer willing or able to properly
discharge its responsibilities as Depositary with respect to such Global
Debenture, and no qualified successor is appointed by the Company within ninety
(90) days of receipt by the Company of such notice, (ii) such Depositary ceases
to be a clearing agency registered under the Exchange Act and no successor is
appointed by the Company within ninety (90) days after obtaining knowledge of
such event, (iii) the Company executes and delivers to the Trustee a Company
Order stating that the Company elects to terminate the book-entry system through
the Depositary or (iv) an Event of Default shall have occurred and be
continuing. Upon the

                                      -18-

<PAGE>

occurrence of any event specified in clause (i), (ii), (iii) or (iv) above, the
Trustee shall notify the Depositary and instruct the Depositary to notify all
owners of beneficial interests in such Global Debenture of the occurrence of
such event and of the availability of Debentures to such owners of beneficial
interests requesting the same. Upon the issuance of such Debentures and the
registration in the Debenture Register of such Debentures in the names of the
Holders of the beneficial interests therein, the Trustee shall recognize such
holders of beneficial interests as Holders.

                  (c) If any Global Debenture is to be exchanged for other
Debentures or canceled in part, or if another Debenture is to be exchanged in
whole or in part for a beneficial interest in any Global Debenture, then either
(i) such Global Debenture shall be so surrendered for exchange or cancellation
as provided in this Article II or (ii) the principal amount thereof shall be
reduced or increased by an amount equal to the portion thereof to be so
exchanged or canceled, or equal to the principal amount of such other Debenture
to be so exchanged for a beneficial interest therein, as the case may be, by
means of an appropriate adjustment made on the records of the Debenture
registrar, whereupon the Trustee, in accordance with the Applicable Depository
Procedures, shall instruct the Depositary or its authorized representative to
make a corresponding adjustment to its records. Upon any such surrender or
adjustment of a Global Debenture by the Depositary, accompanied by registration
instructions, the Company shall execute and the Trustee shall authenticate and
deliver any Debentures issuable in exchange for such Global Debenture (or any
portion thereof) in accordance with the instructions of the Depositary. The
Trustee shall not be liable for any delay in delivery of such instructions and
may conclusively rely on, and shall be fully protected in relying on, such
instructions.

                  (d) Every Debenture authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global
Debenture or any portion thereof shall be authenticated and delivered in the
form of, and shall be, a Global Debenture, unless such Debenture is registered
in the name of a Person other than the Depositary for such Global Debenture or a
nominee thereof.

                  (e) Debentures distributed to holders of Book-Entry Capital
Securities (as defined in the Trust Agreement) upon the dissolution of the Trust
shall be distributed in the form of one or more Global Debentures registered in
the name of a Depositary or its nominee, and deposited with the Debentures
registrar, as custodian for such Depositary, or with such Depositary, for credit
by the Depositary to the respective accounts of the beneficial owners of the
Debentures represented thereby (or such other accounts as they may direct).
Debentures distributed to holders of Capital Securities other than Book-Entry
Capital Securities upon the dissolution of the Trust shall not be issued in the
form of a Global Debenture or any other form intended to facilitate book-entry
trading in beneficial interests in such Debentures.

                  (f) The Depositary or its nominee, as the registered owner of
a Global Debenture, shall be the Holder of such Global Debenture for all
purposes under this Indenture and the Debentures, and owners of beneficial
interests in a Global Debenture shall hold such interests pursuant to the
Applicable Depository Procedures. Accordingly, any such owner's beneficial
interest in a Global Debenture shall be shown only on, and the transfer of such
interest shall be effected only through, records maintained by the Depositary or
its nominee or its Depositary Participants. The Debentures registrar and the
Trustee shall be entitled to deal with

                                      -19-

<PAGE>

the Depositary for all purposes of this Indenture relating to a Global Debenture
(including the payment of principal and interest thereon and the giving of
instructions or directions by owners of beneficial interests therein and the
giving of notices) as the sole Holder of the Debenture and shall have no
obligations to the owners of beneficial interests therein. Neither the Trustee
nor the Debentures registrar shall have any liability in respect of any
transfers affected by the Depositary.

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

                  (h) No holder of any beneficial interest in any Global
Debenture held on its behalf by a Depositary shall have any rights under this
Indenture with respect to such Global Debenture, and such Depositary may be
treated by the Company, the Trustee and any agent of the Company or the Trustee
as the owner of such Global Debenture for all purposes whatsoever. None of the
Company, the Trustee nor any agent of the Company or the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a Global Debenture
or maintaining, supervising or reviewing any records relating to such beneficial
ownership interests. Notwithstanding the foregoing, nothing herein shall prevent
the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by a
Depositary or impair, as between a Depositary and such holders of beneficial
interests, the operation of customary practices governing the exercise of the
rights of the Depositary (or its nominee) as holder of any Debenture.

                                  ARTICLE III

                       PARTICULAR COVENANTS OF THE COMPANY

         SECTION 3.01. Payment of Principal, Premium and Interest; Agreed
Treatment of the Debt Securities.

                  (a) The Company covenants and agrees that it will duly and
punctually pay or cause to be paid all payments due on the Debt Securities at
the place, at the respective times and in the manner provided in this Indenture
and the Debt Securities. At the option of the Company, each installment of
interest on the Debt Securities may be paid (i) by mailing checks for such
interest payable to the order of the holders of Debt Securities entitled thereto
as they appear on the Debt Security Register or (ii) by wire transfer to any
account with a banking institution located in the United States designated by
such Person to the Paying Agent no later than the related record date.

                  (b) The Company will treat the Debt Securities as
indebtedness, and the interest payable in respect of such Debt Securities as
interest, for all U.S. federal income tax purposes. All payments in respect of
such Debt Securities will be made free and clear of U.S. withholding tax to any
beneficial owner thereof that has provided an Internal Revenue Service Form W-8
BEN (or any substitute or successor form) establishing its non-U.S. status for
U.S. federal income tax purposes.

<PAGE>

                  (c) As of the date of this Indenture, the Company has no
intention to exercise its right under Section 2.11 to defer payments of interest
on the Debt Securities by commencing an Extension Period.

                  (d) As of the date of this Indenture, the Company believes
that the likelihood that it would exercise its right under Section 2.11 to defer
payments of interest on the Debt Securities by commencing an Extension Period at
any time during which the Debt Securities are outstanding is remote because of
the restrictions that would be imposed on the Company's ability to declare or
pay dividends or distributions on, or to redeem, purchase or make a liquidation
payment with respect to, any of its outstanding equity and on the Company's
ability to make any payments of principal of or interest on, or repurchase or
redeem, any of its debt securities that rank pari passu in all respects with (or
junior in interest to) the Debt Securities.

         SECTION 3.02. Offices for Notices and Payments, etc.

                  So long as any of the Debt Securities remain outstanding, the
Company will maintain in Wilmington, Delaware or in an office or agency where
the Debt Securities may be presented for payment, an office or agency where the
Debt Securities may be presented for registration of transfer and for exchange
as provided in this Indenture and an office or agency where notices and demands
to or upon the Company in respect of the Debt Securities or of this Indenture
may be served. The Company will give to the Trustee written notice of the
location of any such office or agency and of any change of location thereof.
Until otherwise designated from time to time by the Company in a notice to the
Trustee, or specified as contemplated by Section 2.05, such office or agency for
all of the above purposes shall be the Principal Office of the Trustee. In case
the Company shall fail to maintain any such office or agency in Wilmington,
Delaware or shall fail to give such notice of the location or of any change in
the location thereof, presentations and demands may be made and notices may be
served at the Principal Office of the Trustee.

                  In addition to any such office or agency, the Company may from
time to time designate one or more offices or agencies outside Wilmington,
Delaware or where the Debt Securities may be presented for registration of
transfer and for exchange in the manner provided in this Indenture, 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 will give to the Trustee prompt written notice of any
such designation or rescission thereof.

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

                  The Company, whenever necessary to avoid or fill a vacancy in
the office of Trustee, will appoint, in the manner provided in Section 6.09, a
Trustee, so that there shall at all times be a Trustee hereunder.

         SECTION 3.04. Provision as to Paying Agent.

                  (a) If the Company shall appoint a Paying Agent other than the
Trustee, it will cause such Paying Agent to execute and deliver to the Trustee
an instrument in which such agent shall agree with the Trustee, subject to the
provision of this Section 3.04:;

                           (1) that it will hold all sums held by it as such
                  agent for the payment of all payments due on the Debt
                  Securities (whether such sums have been paid to it by the
                  Company or by any other obligor on the Debt Securities) in
                  trust for the benefit of the holders of the Debt Securities;

                           (2) that it will give the Trustee prompt written
                  notice of any failure by the Company (or by any other obligor
                  on the Debt Securities) to make any payment on the Debt
                  Securities when the same shall be due and payable; and

                           (3) that it will, at any time during the continuance
                  of any Event of Default, upon the written request of the
                  Trustee, forthwith pay to the Trustee all sums so held in
                  trust by such Paying Agent.

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

                  Whenever the Company shall have one or more Paying Agents for
the Debt Securities, it will, on or prior to each due date of the payments on
the Debt Securities, deposit with a Paying Agent a sum sufficient to pay all
payments so becoming due, such sum to be held in trust for the benefit of the
Persons entitled thereto and (unless such Paying Agent is the Trustee) the
Company shall promptly notify the Trustee in writing of its action or failure to
act.

                  (c) Anything in this Section 3.04 to the contrary
notwithstanding, the Company may, at any time, for the purpose of obtaining a
satisfaction and discharge with respect to the Debt Securities, or for any other
reason, pay, or direct any Paying Agent to pay to the Trustee all sums held in
trust by the Company or any such Paying Agent, such sums to be held by the
Trustee upon the same terms and conditions herein contained.

                  (d) Anything in this Section 3.04 to the contrary
notwithstanding, the agreement to hold sums in trust as provided in this Section
3.04 is subject to Sections 12.03 and 12.04.

                  (e) The Company hereby initially appoints the Trustee to act
as Paying Agent (the "Paying Agent").

                                      -22-
<PAGE>

         SECTION 3.05. Certificate to Trustee.

                  The Company will deliver to the Trustee on or before 120 days
after the end of each fiscal year, so long as Debt Securities are outstanding
hereunder, a Certificate stating that in the course of the performance by the
signers of their duties as officers of the Company they would normally have
knowledge of any default by the Company in the performance of any covenants of
the Company contained herein, stating whether or not they have knowledge of any
such default and, if so, specifying each such default of which the signers have
knowledge and the nature thereof.

         SECTION 3.06. Additional Interest.

                  If and for so long as the Trust is the holder of all Debt
Securities and is subject to or otherwise required to pay, or is required to
withhold from distributions to holders of Trust Securities, any additional taxes
(including withholding taxes), duties, assessments or other governmental charges
as a result of a Tax Event, the Company will pay such additional amounts (the
"Additional Interest") on the Debt Securities as shall be required so that the
net amounts received and retained by the Trust for distribution to holders of
Trust Securities after paying all taxes (including withholding taxes on
distributions to holders of Trust Securities), duties, assessments or other
governmental charges will be equal to the amounts the Trust would have received
and retained for distribution to holders of Trust Securities after paying all
taxes (including withholding taxes on distributions to holders of Trust
Securities), duties, assessments or other governmental charges if no such
additional taxes, duties, assessments or other governmental charges had been
imposed. Whenever in this Indenture or the Debt Securities there is a reference
in any context to the payment of principal of or interest on the Debt
Securities, such mention shall be deemed to include mention of payments of the
Additional Interest provided for in this paragraph to the extent that, in such
context, Additional Interest is, was or would be payable in respect thereof
pursuant to the provisions of this paragraph and express mention of the payment
of Additional Interest (if applicable) in any provisions hereof shall not be
construed as excluding Additional Interest in those provisions hereof where such
express mention is not made, provided, however, that the deferral of the payment
of interest during an Extension Period pursuant to Section 2.11 shall not defer
the payment of any Additional Interest that may be due and payable.

         SECTION 3.07. Compliance with Consolidation Provisions.

                  The Company will not, while any of the Debt Securities remain
outstanding, consolidate with, or merge into any other Person, or merge into
itself, or sell or convey all or substantially all of its property to any other
Person unless the provisions of Article XI hereof are complied with.

         SECTION 3.08. Limitation on Dividends.

                  If Debt Securities are initially issued to the Trust or a
trustee of such Trust in connection with the issuance of Trust Securities by the
Trust (regardless of whether Debt Securities continue to be held by such Trust)
and (i) there shall have occurred and be continuing an Event of Default, (ii)
the Company shall be in default with respect to its payment of any

                                      -23-
<PAGE>

obligations under the Capital Securities Guarantee or (iii) the Company shall
have given notice of its election to defer payments of interest on the Debt
Securities by extending the interest payment period as provided herein and such
period, or any extension thereof, shall have commenced and be continuing, then
the Company may not (A) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
the Company's capital stock or (B) make any payment of principal of or interest
or premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu in all respects with or junior in interest to the
Debt Securities (other than (a) repurchases, redemptions or other acquisitions
of shares of capital stock of the Company (I) in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of
one or more employees, officers, directors or consultants, (II) in connection
with a dividend reinvestment or stockholder stock purchase plan or (III) in
connection with the issuance of capital stock of the Company (or securities
convertible into or exercisable for such capital stock), as consideration in an
acquisition transaction entered into prior to the occurrence of (i), (ii) or
(iii) above, (b) as a result of any exchange or conversion of any class or
series of the Company's capital stock (or any capital stock of a subsidiary of
the Company) for any class or series of the Company's capital stock or of any
class or series of the Company's indebtedness for any class or series of the
Company's capital stock, (c) the purchase of fractional interests in shares of
the Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any stockholder's rights plan, or
the issuance of rights, stock or other property under any stockholder's rights
plan, or the redemption or repurchase of rights pursuant thereto, or (e) any
dividend in the form of stock, warrants, options or other rights where the
dividend stock or the stock issuable upon exercise of such warrants, options or
other rights is the same stock as that on which the dividend is being paid or
ranks pari passu with or junior to such stock and any cash payments in lieu of
fractional shares issued in connection therewith, or (f) payments under the
Capital Securities Guarantee).

         SECTION 3.09. Covenants as to the Trust.

                  For so long as such Trust Securities remain outstanding, the
Company shall maintain 100% ownership of the Common Securities; provided,
however, that any permitted successor of the Company under this Indenture that
is a U.S. Person may succeed to the Company's ownership of such Common
Securities. The Company, as owner of the Common Securities, shall use
commercially reasonable efforts to cause the Trust (a) to remain a statutory
trust, except in connection with a distribution of Debt Securities to the
holders of Trust Securities in liquidation of the Trust, the redemption of all
of the Trust Securities or certain mergers, consolidations or amalgamations,
each as permitted by the Declaration, (b) to otherwise continue to be classified
as a grantor trust for United States federal income tax purposes and (c) to
cause each holder of Trust Securities to be treated as owning an undivided
beneficial interest in the Debt Securities.

                LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

         SECTION 4.01. Securityholders' Lists.

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

                  (a) on each regular record date for an Interest Payment Date,
a list, in such form as the Trustee may reasonably require, of the names and
addresses of the Securityholders of the Debt Securities as of such record date;
and

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

                  (c) except that no such lists need be furnished under this
Section 4.01 so long as the Trustee is in possession thereof by reason of its
acting as Debt Security registrar.

         SECTION 4.02. Preservation and Disclosure of Lists.

                  (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the
holders of Debt Securities (1) contained in the most recent list furnished to it
as provided in Section 4.01 or (2) received by it in the capacity of Debt
Securities registrar (if so acting) hereunder. The Trustee may destroy any list
furnished to it as provided in Section 4.01 upon receipt of a new list so
furnished.

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

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

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

                                      -25-
<PAGE>

                  If the Trustee shall elect not to afford such applicants
access to such information, the Trustee shall, upon the written request of such
applicants, mail to each Securityholder of Debt Securities whose name and
address appear in the information preserved at the time by the Trustee in
accordance with the provisions of subsection (a) of this Section 4.02 a copy of
the form of proxy or other communication which is specified in such request with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender, the Trustee shall mail to
such applicants and file with the Securities and Exchange Commission, if
permitted or required by applicable law, together with a copy of the material to
be mailed, a written statement to the effect that, in the opinion of the
Trustee, such mailing would be contrary to the best interests of the holders of
all Debt Securities, as the case may be, or would be in violation of applicable
law. Such written statement shall specify the basis of such opinion. If said
Commission, as permitted or required by applicable law, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, said Commission shall
find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Securityholders with reasonable
promptness after the entry of such order and the renewal of such tender;
otherwise the Trustee shall be relieved of any obligation or duty to such
applicants respecting their application.

                  (c) Each and every holder of Debt Securities, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor any Paying Agent shall be held accountable by reason
of the disclosure of any such information as to the names and addresses of the
holders of Debt Securities in accordance with the provisions of subsection (b)
of this Section 4.02, regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under said subsection (b).

          REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS UPON AN EVENT OF
                                    DEFAULT

         SECTION 5.01. Events of Default.

                  (a) The following events shall be "Events of Default" with
respect to Debt Securities:

                  (b) the Company defaults in the payment of any interest upon
any Debt Security when it becomes due and payable, and continuance of such
default for a period of 30 days; for the avoidance of doubt, an extension of any
interest payment period by the Company in accordance with Section 2.11 of this
Indenture shall not constitute a default under this clause 5.01(a); or

                  (c) the Company defaults in the payment of all or any part of
the principal of (or premium, if any, on) any Debt Securities as and when the
same shall become due and payable

                                      -26-

either at maturity, upon redemption, by declaration of acceleration pursuant to
Section 5.01 of this Indenture or otherwise; or

                  (d) the Company defaults in the performance of, or breaches,
any of its covenants or agreements in Sections 3.06, 3.07, 3.08 or 3.09 of this
Indenture (other than a covenant or agreement a default in whose performance or
whose breach is elsewhere in this Section specifically dealt with), and
continuance of such default or breach for a period of 90 days after there has
been given, by registered or certified mail, to the Company by the Trustee or to
the Company and the Trustee by the holders of not less than 25% in aggregate
principal amount of the outstanding Debt Securities, a written notice specifying
such default or breach and requiring it to be remedied and stating that such
notice is a "Notice of Default' hereunder; or

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

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

                  (g) the Trust shall have voluntarily or involuntarily
liquidated, dissolved, wound-up its business or otherwise terminated its
existence except in connection with (1) the distribution of the Debt Securities
to holders of the Trust Securities in liquidation of their interests in the
Trust, (2) the redemption of all of the outstanding Trust Securities or (3)
certain mergers, consolidations or amalgamations, each as permitted by the
Declaration.

                  If an Event of Default occurs and is continuing with respect
to the Debt Securities, then, and in each and every such case, unless the
principal of the Debt Securities shall have already become due and payable,
either the Trustee or the holders of not less than 25% in aggregate principal
amount of the Debt Securities then outstanding hereunder, by notice in writing
to the Company (and to the Trustee if given by Securityholders), may declare the
entire principal of the Debt Securities and the interest accrued, but unpaid,
thereon, if any, to be due and payable immediately, and upon any such
declaration the same shall become immediately due and payable.

                  The foregoing provisions, however, are subject to the
condition that if, at any time after the principal of the Debt Securities shall
have been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, (i) the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Debt
Securities and all

                                      -27-
<PAGE>

payments on the Debt Securities which shall have become due otherwise than by
acceleration (with interest upon all such payments and Deferred Interest, to the
extent permitted by law) and such amount as shall be sufficient to cover
reasonable compensation to the Trustee and each predecessor Trustee, their
respective agents, attorneys and counsel, and all other amounts due to the
Trustee pursuant to Section 6.06, if any, and (ii) all Events of Default under
this Indenture, other than the non-payment of the payments on Debt Securities
which shall have become due by acceleration, shall have been cured, waived or
otherwise remedied as provided herein, then and in every such case the holders
of a majority in aggregate principal amount of the Debt Securities then
outstanding, by written notice to the Company and to the Trustee, may waive all
defaults and rescind and annul such declaration and its consequences, but no
such waiver or rescission and annulment shall extend to or shall affect any
subsequent default or shall impair any right consequent thereon.

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

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

                  The Company covenants that upon the occurrence of an Event of
Default pursuant to clause 5.01(a) or 5.01(b) and upon demand of the Trustee,
the Company will pay to the Trustee, for the benefit of the holders of the Debt
Securities, the whole amount that then shall have become due and payable on all
Debt Securities including Deferred Interest accrued on the Debt Securities; and,
in addition thereto, such further amount as shall be sufficient to cover the
costs and expenses of collection, including a reasonable compensation to the
Trustee, its agents, attorneys and counsel, and any other amounts due to the
Trustee under Section 6.06. In case the Company shall fail forthwith to pay such
amounts upon such demand, the Trustee, in its own name and as trustee of an
express trust, shall be entitled and empowered to institute any actions or
proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such action or proceeding to judgment or final
decree, and may enforce any such judgment or final decree against the Company or
any other obligor on such Debt Securities and collect in the manner provided by
law out of the property of the Company or any other obligor on such Debt
Securities wherever situated the moneys adjudged or decreed to be payable.

                  In case there shall be pending proceedings for the bankruptcy
or for the reorganization of the Company or any other obligor on the Debt
Securities under Bankruptcy Law, or in case a receiver or trustee shall have
been appointed for the property of the Company or such other obligor, or in the
case of any other similar judicial proceedings relative to the Company or other
obligor upon the Debt Securities, or to the creditors or property of the Company
or such other obligor, the Trustee, irrespective of whether the principal of the
Debt Securities shall then be due and payable as therein expressed or by
declaration of acceleration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 5.02,
shall be entitled and empowered, by intervention in such

                                      -28-
<PAGE>

proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal and interest owing and unpaid in respect of the Debt
Securities and, in case of any judicial proceedings, to file such proofs of
claim and other papers or documents as may be necessary or advisable in order to
have the claims of the Trustee (including any claim for reasonable compensation
to the Trustee and each predecessor Trustee, and their respective agents,
attorneys and counsel, and for reimbursement of all other amounts due to the
Trustee under Section 6.06) and of the Securityholders allowed in such judicial
proceedings relative to the Company or any other obligor on the Debt Securities,
or to the creditors or property of the Company or such other obligor, unless
prohibited by applicable law and regulations, to vote on behalf of the holders
of the Debt Securities in any election of a trustee or a standby trustee in
arrangement, reorganization, liquidation or other bankruptcy or insolvency
proceedings or Person performing similar functions in comparable proceedings,
and to collect and receive any moneys or other property payable or deliverable
on any such claims, and to distribute the same after the deduction of its
charges and expenses; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the Securityholders to make such
payments to the Trustee, and, in the event that the Trustee shall consent to the
making of such payments directly to the Securityholders, to pay to the Trustee
such amounts as shall be sufficient to cover reasonable compensation to the
Trustee, each predecessor Trustee and their respective agents, attorneys and
counsel, and all other amounts due to the Trustee under Section 6.06.

                  Nothing herein contained shall be construed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Debt Securities or the rights of any holder thereof or
to authorize the Trustee to vote in respect of the claim of any Securityholder
in any such proceeding.

                  All rights of action and of asserting claims under this
Indenture, or under any of the Debt Securities, may be enforced by the Trustee
without the possession of any of the Debt Securities, 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 be for the ratable
benefit of the holders of the Debt Securities.

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

         SECTION 5.03. Application of Moneys Collected by Trustee.

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

                                      -29-
<PAGE>

                  First: To the payment of costs and expenses incurred by, and
reasonable fees of, the Trustee, its agents, attorneys and counsel, and of all
other amounts due to the Trustee under Section 6.06;

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

                  Third: To the payment of the amounts then due and unpaid upon
Debt Securities, in respect of which or for the benefit of which money has been
collected, ratably, without preference or priority of any kind, according to the
amounts due on such Debt Securities; and

                  Fourth: The balance, if any, to the Company.

         SECTION 5.04. Proceedings by Securityholders.

                  No holder of any Debt Security shall have any right to
institute any suit, action or proceeding for any remedy hereunder, unless such
holder previously shall have given to the Trustee written notice of an Event of
Default with respect to the Debt Securities and unless the holders of not less
than 25% in aggregate principal amount of the Debt Securities then outstanding
shall have given the Trustee a written request to institute such action, suit or
proceeding and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred thereby,
and the Trustee for 60 days after its receipt of such notice, request and offer
of indemnity shall have failed to institute any such action, suit or proceeding;
provided, that no holder of Debt Securities shall have any right to prejudice
the rights of any other holder of Debt Securities, obtain priority or preference
over any other such holder or enforce any right under this Indenture except in
the manner herein provided and for the equal, ratable and common benefit of all
holders of Debt Securities.

                  Notwithstanding any other provisions in this Indenture,
however, the right of any holder of any Debt Security to receive payment of the
principal of, premium, if any, and interest on such Debt Security when due, or
to institute suit for the enforcement of any such payment, shall not be impaired
or affected without the consent of such holder. For the protection and
enforcement of the provisions of this Section, each and every Securityholder and
the Trustee shall be entitled to such relief as can be given either at law or in
equity.

         SECTION 5.05. Proceedings by Trustee.

                  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 by suit in
equity or by action at law or by proceeding in bankruptcy or otherwise, whether
for the specific enforcement of any covenant or agreement contained in this
Indenture or in aid of the exercise of any power granted in this Indenture, or
to enforce any other legal or equitable right vested in the Trustee by this
Indenture or by law.

                                      -30-
<PAGE>

         SECTION 5.06. Remedies Cumulative and Continuing.

                  Except as otherwise provided in Section 2.06, all powers and
remedies given by this Article V to the Trustee or to the Securityholders shall,
to the extent permitted by law, be deemed cumulative and not exclusive of any
other powers and remedies available to the Trustee or the holders of the Debt
Securities, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to the Debt Securities, and no delay or
omission of the Trustee or of any holder of any of the Debt Securities to
exercise any right or power accruing upon any Event of Default occurring and
continuing as aforesaid shall impair any such right or power, or shall be
construed to be a waiver of any such default or an acquiescence therein; and,
subject to the provisions of Section 5.04, every power and remedy given by this
Article V or by law to the Trustee or to the Securityholders may be exercised
from time to time, and as often as shall be deemed expedient, by the Trustee or
by the Securityholders.

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

                  The holders of a majority in aggregate principal amount of the
Debt Securities affected (voting as one class) at the time outstanding shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee with respect to such Debt Securities; provided,
however, that (subject to the provisions of Section 6.01) the Trustee shall have
the right to decline to follow any such direction if the Trustee shall determine
that the action so directed would be unjustly prejudicial to the holders not
taking part in such direction or if the Trustee being advised by counsel
determines that the action or proceeding so directed may not lawfully be taken
or if a Responsible Officer of the Trustee shall determine that the action or
proceedings so directed would involve the Trustee in personal liability. Prior
to any declaration accelerating the maturity of the Debt Securities, the holders
of a majority in aggregate principal amount of the Debt Securities at the time
outstanding may on behalf of the holders of all of the Debt Securities waive (or
modify any previously granted waiver of) any past default or Event of Default
and its consequences, except a default (a) in the payment of principal of,
premium, if any, or interest on any of the Debt Securities, (b) in respect of
covenants or provisions hereof which cannot be modified or amended without the
consent of the holder of each Debt Security affected, or (c) in respect of the
covenants contained in Section 3.09; provided, however, that if the Debt
Securities are held by the Trust or a trustee of such trust, such waiver or
modification to such waiver shall not be effective until the holders of a
majority in liquidation preference of the Trust Securities of the Trust shall
have consented to such waiver or modification to such waiver; provided, further,
that if the consent of the holder of each outstanding Debt Security is required,
such waiver shall not be effective until each holder of the Trust Securities of
the 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 Debt Securities shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or Event of Default
or impair any right consequent thereon. Whenever any default or Event of Default
hereunder shall have been waived as permitted by this Section 5.07, said default
or Event of Default shall for all purposes of the Debt Securities and this
Indenture be deemed to have been cured and to be not continuing.

         SECTION 5.08. Notice of Defaults.

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

         SECTION 5.09. Undertaking to Pay Costs.

                  All parties to this Indenture agree, and each holder of any
Debt Security 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 reasonable costs, including
reasonable attorneys' fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; but the provisions of this Section 5.09 shall not
apply to any suit instituted by the Trustee, to any suit instituted by any
Securityholder, or group of Securityholders, holding in the aggregate more than
10% in principal amount of the Debt Securities outstanding, or to any suit
instituted by any Securityholder for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Debt Security against the
Company on or after the same shall have become due and payable.

                                   ARTICLE VI

                             CONCERNING THE TRUSTEE

         SECTION 6.01. Duties and Responsibilities of Trustee.

                  With respect to the holders of Debt Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Debt Securities and after the curing or waiving of all Events of
Default which may have occurred, with respect to the Debt Securities, undertakes
to perform such duties and only such duties as are specifically set forth in
this Indenture. In case an Event of Default with respect to the Debt Securities
has occurred (which has not been cured or waived) the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of such person's own affairs.

                                      -32-
<PAGE>

                  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:

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

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

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

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

                  (c) the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith, in accordance with the
direction of the Securityholders pursuant to Section 5.07, relating to the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred upon the Trustee, under this
Indenture;

                  (d) the Trustee shall not be charged with knowledge of any
Default or Event of Default with respect to the Debt Securities unless either
(1) a Responsible Officer shall have actual knowledge of such Default or Event
of Default or (2) written notice of such Default or Event of Default shall have
been given to the Trustee by the Company or any other obligor on the Debt
Securities or by any holder of the Debt Securities, except with respect to an
Event of Default pursuant to Sections 5.01 (a) or 5.01 (b) hereof (other than an
Event of Default resulting from the default in the payment of Additional
Interest or premium, if any, if the Trustee does not have actual knowledge or
written notice that such payment is due and payable), of which the Trustee shall
be deemed to have knowledge; and

                  (e) in the absence of bad faith on the part of the Trustee,
the Trustee may seek and rely on reasonable instructions from the Company.

                                      -33-
<PAGE>

                  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.

         SECTION 6.02. Reliance on Documents, Opinions, etc.

                  Except as otherwise provided in Section 6.01:

                  (a) the Trustee may conclusively rely and shall be fully
protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, bond,
note, debenture or other paper or document believed by it in good faith 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 an Officers' Certificate
(unless other evidence in respect thereof be herein specifically prescribed);
and any Board Resolution may be evidenced to the Trustee by a copy thereof
certified by the Secretary or an Assistant Secretary of the Company;

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

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

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

                  (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, coupon or other paper or document, unless requested in writing to do
so by the holders of not less than a majority in principal amount of the
outstanding Debt Securities affected thereby; provided, however, that if the
payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such expense or liability as a condition to so
proceeding; and

                                      -34-
<PAGE>

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

         SECTION 6.03. No Responsibility for Recitals, etc.

                  The recitals contained herein and in the Debt Securities
(except in the certificate of authentication of the Trustee or the
Authenticating Agent) shall be taken as the statements of the Company and the
Trustee and the Authenticating Agent assume no responsibility for the
correctness of the same. The Trustee and the Authenticating Agent make no
representations as to the validity or sufficiency of this Indenture or of the
Debt Securities. The Trustee and the Authenticating Agent shall not be
accountable for the use or application by the Company of any Debt Securities or
the proceeds of any Debt Securities authenticated and delivered by the Trustee
or the Authenticating Agent in conformity with the provisions of this Indenture.

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

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

         SECTION 6.05. Moneys to be Held in Trust.

                  Subject to the provisions of Section 12.04, all moneys
received by the Trustee or any Paying Agent shall, until used or applied as
herein provided, be held in trust for the purpose for which they were received,
but need not be segregated from other funds except to the extent required by
law. The Trustee and any Paying Agent shall be under no liability for interest
on any money received by it hereunder except as otherwise agreed in writing with
the Company. So long as no Event of Default shall have occurred and be
continuing, all interest allowed on any such moneys, if any, shall be paid from
time to time to the Company upon the written order of the Company, signed by the
Chairman of the Board of Directors, the President, the Chief Operating Officer,
a Vice President, the Treasurer or an Assistant Treasurer of the Company.

         SECTION 6.06. Compensation and Expenses of Trustee.

                  The Company covenants and agrees to pay to the Trustee from
time to time, and the Trustee shall be entitled to, such compensation as shall
be agreed to in writing between the Company and the Trustee (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust), and the Company will pay or reimburse the Trustee upon its
written request for all documented reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any of the
provisions of this Indenture (including the reasonable compensation and the
reasonable expenses and disbursements of its counsel and of all Persons not
regularly in its employ) except any such expense, disbursement or advance that
arises from its negligence or bad faith. The Company also covenants to indemnify
each of the Trustee (including in its individual capacity) and any

                                      -35-
<PAGE>

predecessor Trustee (and its officers, agents, directors and employees) for, and
to hold it harmless against, any and all loss, damage, claim, liability or
expense including taxes (other than taxes based on the income of the Trustee),
except to the extent such loss, damage, claim, liability or expense results from
the negligence or bad faith of such indemnitee, 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 or liability in the premises. The
obligations of the Company under this Section 6.06 to compensate and indemnify
the Trustee and to pay or reimburse the Trustee for documented expenses,
disbursements and advances shall constitute additional indebtedness hereunder.
Such additional indebtedness shall be secured by a lien prior to that of the
Debt Securities upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the benefit of the holders of particular
Debt Securities.

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

                  The provisions of this Section shall survive the resignation
or removal of the Trustee and the defeasance or other termination of this
Indenture.

         SECTION 6.07. Officers' Certificate as Evidence.

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

         SECTION 6.08. Eligibility of Trustee.

                  The Trustee hereunder shall at all times be a U.S. Person that
is a banking corporation or national association organized and doing business
under the laws of the United States of America or any state thereof or of the
District of Columbia and authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least fifty million U.S.
dollars ($50,000,000) and subject to supervision or examination by federal,
state, or District of Columbia authority. If such corporation or national
association 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 6.08 the combined capital and surplus of such
corporation or national association shall be deemed to be its combined capital
and surplus as set forth in its most recent records of condition so published.

                                      -36-
<PAGE>

                  The Company may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Company, serve as
Trustee, notwithstanding that such corporation or national association shall be
otherwise eligible and qualified under this Article.

                  In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.08, the Trustee shall resign
immediately in the manner and with the effect specified in Section 6.09.

                  If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee
shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to this Indenture.

         SECTION 6.09. Resignation or Removal of Trustee, Calculation Agent,
Paying Agent or Debt Security Registrar.

                  (a) The Trustee, or any trustee or trustees hereafter
appointed, the Calculation Agent, the Paying Agent and any Debt Security
Registrar may at any time resign by giving written notice of such resignation to
the Company and by mailing notice thereof, at the Company's expense, to the
holders of the Debt Securities at their addresses as they shall appear on the
Debt Security Register. Upon receiving such notice of resignation, the Company
shall promptly appoint a successor or successors by written instrument, in
duplicate, executed by order of its Board of Directors, one copy of which
instrument shall be delivered to the resigning party and one copy to the
successor. If no successor shall have been so appointed and have accepted
appointment within 30 days after the mailing of such notice of resignation to
the affected Securityholders, the resigning party may petition any court of
competent jurisdiction for the appointment of a successor, or any Securityholder
who has been a bona fide holder of a Debt Security or Debt Securities for at
least six months may, subject to the provisions of Section 5.09, on behalf of
himself or herself and all others similarly situated, petition any such court
for the appointment of a successor. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, appoint a successor.

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

                           (1) the Trustee shall fail to comply with the
                  provisions of the last paragraph of Section 6.08 after written
                  request therefor by the Company or by any Securityholder who
                  has been a bona fide holder of a Debt Security or Debt
                  Securities for at least six months,

                           (2) the Trustee shall cease to be eligible in
                  accordance with the provisions of Section 6.08 and shall fail
                  to resign after written request therefor by the Company or by
                  any such Securityholder, or

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

                                      -37-
<PAGE>

then, in any such case, the Company may remove the Trustee and appoint a
successor Trustee by written instrument, in duplicate, executed by order of the
Board of Directors, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor Trustee, or, subject to the
provisions of Section 5.09, if no successor Trustee shall have been so appointed
and have accepted appointment within 30 days of the occurrence of any of (1),
(2) or (3) above, any Securityholder who has been a bona fide holder of a Debt
Security or Debt Securities for at least six months may, on behalf of himself or
herself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, remove the Trustee and appoint a successor Trustee.

                  (c) Upon prior written notice to the Company and the Trustee,
the holders of a majority in aggregate principal amount of the Debt Securities
at the time outstanding may at any time remove the Trustee and nominate a
successor Trustee, which shall be deemed appointed as successor Trustee unless
within ten Business Days after such nomination the Company objects thereto, in
which case or in the case of a failure by such holders to nominate a successor
Trustee, the Trustee so removed or any Securityholder, upon the terms and
conditions and otherwise as in subsection (a) of this Section 6.09 provided, may
petition any court of competent jurisdiction for an appointment of a successor.

                  (d) Any resignation or removal of the Trustee, the Calculation
Agent, the Paying Agent and any Debt Security Registrar and appointment of a
successor pursuant to any of the provisions of this Section 6.09 shall become
effective upon acceptance of appointment by the successor as provided in Section
6.10.

         SECTION 6.10. Acceptance by Successor.

                  Any successor Trustee, Calculation Agent, Paying Agent or Debt
Security Registrar appointed as provided in Section 6.09 shall execute,
acknowledge and deliver to the Company and to its predecessor an instrument
accepting such appointment hereunder, and thereupon the resignation or removal
of the retiring party shall become effective and such successor, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations with respect to the Debt Securities of its
predecessor hereunder, with like effect as if originally named herein; but,
nevertheless, on the written request of the Company or of the successor, the
party ceasing to act shall, upon payment of the amounts then due it pursuant to
the provisions of Section 6.06, execute and deliver an instrument transferring
to such successor all the rights and powers of the party so ceasing to act and
shall duly assign, transfer and deliver to such successor all property and money
held by such retiring party hereunder. Upon request of any such successor, the
Company shall execute any and all instruments in writing for more fully and
certainly vesting in and confirming to such successor all such rights and
powers. Any party ceasing to act shall, nevertheless, retain a lien upon all
property or funds held or collected to secure any amounts then due it pursuant
to the provisions of Section 6.06.

                  If a successor Trustee is appointed, the Company, the retiring
Trustee and the successor Trustee 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,

                                      -38-
<PAGE>

trusts and duties of the retiring Trustee with respect to the Debt Securities 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 Trust 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.

                  No successor Trustee shall accept appointment as provided in
this Section 6.10 unless at the time of such acceptance such successor Trustee
shall be eligible and qualified under the provisions of Section 6.08.

                  In no event shall a retiring Trustee, Calculation Agent,
Paying Agent or Debt Security Registrar be liable for the acts or omissions of
any successor hereunder.

                  Upon acceptance of appointment by a successor Trustee,
Calculation Agent, Paying Agent or Debt Security Registrar as provided in this
Section 6.10, the Company shall mail notice of the succession to the holders of
Debt Securities at their addresses as they shall appear on the Debt Security
Register. If the Company fails to mail such notice within ten Business Days
after the acceptance of appointment by the successor, the successor shall cause
such notice to be mailed at the expense of the Company.

         SECTION 6.11. Succession by Merger, etc.

                  Any Person into which the Trustee may be merged or converted
or with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any Person
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder without the execution
or filing of any paper or any further act on the part of any of the parties
hereto; provided, that such Person shall be otherwise eligible and qualified
under this Article.

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

         SECTION 6.12. Authenticating Agents.

                  There may be one or more Authenticating Agents appointed by
the Trustee upon the request of the Company with power to act on its behalf and
subject to its direction in the

                                      -39-
<PAGE>

authentication and delivery of Debt Securities issued upon exchange or
registration of transfer thereof as fully to all intents and purposes as though
any such Authenticating Agent had been expressly authorized to authenticate and
deliver Debt Securities; provided, that the Trustee shall have no liability to
the Company for any acts or omissions of the Authenticating Agent with respect
to the authentication and delivery of Debt Securities. Any such Authenticating
Agent shall at all times be a Person organized and doing business under the laws
of the United States or of any state or territory thereof or of the District of
Columbia authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of at least $50,000,000 and being subject to
supervision or examination by federal, state, territorial or District of
Columbia authority. If such Person publishes reports of condition at least
annually pursuant to law or the requirements of such authority, then for the
purposes of this Section 6.12 the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect herein specified in
this Section.

                  Any Person into which any Authenticating Agent may be merged
or converted or with which it may be consolidated, or any Person resulting from
any merger, consolidation or conversion to which any Authenticating Agent shall
be a party, or any Person succeeding to all or substantially all of the
corporate trust business of any Authenticating Agent, shall be the successor of
such Authenticating Agent hereunder, if such successor Person is otherwise
eligible under this Section 6.12 without the execution or filing of any paper or
any further act on the part of the parties hereto or such Authenticating Agent.

                  Any Authenticating Agent may at any time resign by giving
written notice of resignation to the Trustee and to the Company. The Trustee may
at any time terminate the agency of any Authenticating Agent with respect to the
Debt Securities by giving written notice of termination to such Authenticating
Agent and to the Company. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time any Authenticating Agent shall cease
to be eligible under this Section 6.12, the Trustee may, and upon the request of
the Company shall, promptly appoint a successor Authenticating Agent eligible
under this Section 6.12, shall give written notice of such appointment to the
Company and shall mail notice of such appointment to all holders of Debt
Securities as the names and addresses of such holders appear on the Debt
Security Register. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all rights, powers, duties and
responsibilities with respect to the Debt Securities of its predecessor
hereunder, with like effect as if originally named as Authenticating Agent
herein.

                  The Company agrees to pay to any Authenticating Agent from
time to time reasonable compensation for its services. Any Authenticating Agent
shall have no responsibility or liability for any action taken by it as such in
accordance with the directions of the Trustee and shall receive such reasonable
indemnity as it may require against the costs, expenses and liabilities incurred
in furtherance of its duties under this Section 6.12.

                                  ARTICLE VII

                         CONCERNING THE SECURITYHOLDERS

         SECTION 7.01. Action by Securityholders.

                  Whenever in this Indenture it is provided that the holders of
a specified percentage in aggregate principal amount of the Debt Securities may
take any action (including the making of any demand or request, the giving of
any notice, consent or waiver or the taking of any other action), the fact that
at the time of taking any such action the holders of such specified percentage
have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by such Securityholders in person or by
agent or proxy appointed in writing, or (b) by the record of such holders of
Debt Securities voting in favor thereof at any meeting of such Securityholders
duly called and held in accordance with the provisions of Article VIII, or (c)
by a combination of such instrument or instruments and any such record of such a
meeting of such Securityholders, or (d) by any other method the Trustee deems
satisfactory.

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

         SECTION 7.02. Proof of Execution by Securityholders.

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

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

                                      -41-
<PAGE>

         SECTION 7.03. Who Are Deemed Absolute Owners.

                  Prior to due presentment for registration of transfer of any
Debt Security, the Company, the Trustee, any Authenticating Agent, any Paying
Agent, any transfer agent and any Debt Security registrar may deem the Person in
whose name such Debt Security shall be registered upon the Debt Security
Register to be, and may treat such Person as, the absolute owner of such Debt
Security (whether or not such Debt Security shall be overdue) for the purpose of
receiving payment of or on account of the principal of, premium, if any, and
interest on such Debt Security and for all other purposes; and neither the
Company nor the Trustee nor any Authenticating Agent nor any Paying Agent nor
any transfer agent nor any Debt Security registrar shall be affected by any
notice to the contrary. All such payments so made to any holder for the time
being or upon such holder's order shall be valid, and, to the extent of the sum
or sums so paid, effectual to satisfy and discharge the liability for moneys
payable upon any such Debt Security.

         SECTION 7.04. Debt Securities Owned by Company Deemed Not Outstanding.

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

         SECTION 7.05. Revocation of Consents; Future Holders Bound.

                  At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 7.01, of the taking of any action by the holders
of the percentage in aggregate principal amount of the Debt Securities specified
in this Indenture in connection with such action, any holder (in cases where no
record date has been set pursuant to Section 7.01) or any holder as of an
applicable record date (in cases where a record date has been set pursuant to
Section 7.01) of a Debt Security (or any Debt Security issued in whole or in
part in exchange or substitution therefor) the serial number of which is shown
by the evidence to be included in the Debt Securities the holders of which have
consented to such action may, by filing written notice with the Trustee at the
Principal Office of the Trustee and upon proof of holding as provided in Section
7.02, revoke such action so far as concerns such Debt Security (or so far as
concerns the principal amount represented by any exchanged or substituted Debt
Security). Except as aforesaid any such action taken by the holder of any Debt
Security shall be conclusive and

                                      -42-
<PAGE>

binding upon such holder and upon all future holders and owners of such Debt
Security, and of any Debt Security issued in exchange or substitution therefor
or on registration of transfer thereof, irrespective of whether or not any
notation in regard thereto is made upon such Debt Security or any Debt Security
issued in exchange or substitution therefor.

                                  ARTICLE VIII

                            SECURITYHOLDERS' MEETINGS

         SECTION 8.01. Purposes of Meetings.

from time to time pursuant to the provisions of this Article VIII for any of the
following purposes:

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

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

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

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

         SECTION 8.02. Call of Meetings by Trustee.

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

         SECTION 8.03. Call of Meetings by Company or Securityholders.

                  In case at any time the Company pursuant to a Board
Resolution, or the holders of at least 10% in aggregate principal amount of the
Debt Securities, as the case may be, then outstanding, shall have requested the
Trustee to call a meeting of Securityholders, by written request setting forth
in reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within 20 days after
receipt of such request, then the Company or such Securityholders may determine
the time and the place in for

                                      -43-
<PAGE>

such meeting and may call such meeting to take any action authorized in Section
8.01, by mailing notice thereof as provided in Section 8.02.

         SECTION 8.04. Qualifications for Voting.

                  To be entitled to vote at any meeting of Securityholders a
Person shall be (a) a holder of one or more Debt Securities with respect to
which the meeting is being held or (b) a Person appointed by an instrument in

representatives of the Company and its counsel.

         SECTION 8.05. Regulations.

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

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

                  Subject to the provisions of Section 7.04, at any meeting each
holder of Debt Securities with respect to which such meeting is being held or
proxy therefor shall be entitled to one vote for each $1,000 principal amount of
Debt Securities held or represented by such holder; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Debt Security
challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote other than
by virtue of Debt Securities held by such chairman or instruments in writing as
aforesaid duly designating such chairman as the Person to vote on behalf of
other Securityholders. Any meeting of Securityholders duly called pursuant to
the provisions of Section 8.02 or 8.03 may be adjourned from time to time by a

         SECTION 8.06. Voting.

                  The vote upon any resolution submitted to any meeting of
holders of Debt Securities with respect to which such meeting is being held
shall be by written ballots on which shall be subscribed the signatures of such
holders or of their representatives by proxy and the serial number or numbers of
the Debt Securities held or represented by them. The permanent chairman of the
meeting shall appoint two inspectors of votes who shall count all votes cast at
the meeting for or against any resolution and who shall make and file with the
secretary of the

                                      -44-

meeting. A record in duplicate of the proceedings of each meeting of
Securityholders shall be prepared by the secretary of the meeting and there
shall be attached to said record the original reports of the inspectors of votes
on any vote by ballot taken thereat and affidavits by one or more Persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was mailed as provided in Section 8.02. The record
shall show the serial numbers of the Debt Securities voting in favor of or
against any resolution. The record shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one of the
duplicates shall be delivered to the Company and the other to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

         SECTION 8.07. Quorum; Actions.

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

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

                  Any resolution passed or decision taken at any meeting of
holders of Debt Securities duly held in accordance with this Section shall be

                                   ARTICLE IX

                             SUPPLEMENTAL INDENTURES

         SECTION 9.01. Supplemental Indentures without Consent of
Securityholders.

                  The Company, when authorized by a Board Resolution, and the
Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto, without the consent of the Securityholders, for
one or more of the following purposes:

                  (a) to evidence the succession of another Person to the
Company, or successive successions, and the assumption by the successor Person
of the covenants, agreements and obligations of the Company, pursuant to Article
XI hereof;

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

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

                  (d) to add to, delete from, or revise the terms of Debt
Securities, including, without limitation, any terms relating to the issuance,
exchange, registration or transfer of Debt Securities, including to provide for
transfer procedures and restrictions substantially similar to those applicable
to the Capital Securities, as required by Section 2.05 (for purposes of assuring
that no registration of Debt Securities is required under the Securities Act of
1933, as amended); provided, that any such action shall not adversely affect the
interests of the holders of the Debt Securities then outstanding (it being
understood, for purposes of this proviso, that transfer restrictions on Debt
Securities substantially similar to those applicable to Capital Securities shall
not be deemed to adversely affect the holders of the Debt Securities);

                  (e) to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee with respect to the Debt Securities and to add
to or change any of the

                                      -46-
<PAGE>

provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, pursuant to
the requirements of Section 6.10;

                  (f) to make any change (other than as elsewhere provided in
this paragraph) that does not adversely affect the rights of any Securityholder
in any material respect; or

                  (g) to provide for the issuance of and establish the form and
terms and conditions of the Debt Securities, to establish the form of any
certifications required to be furnished pursuant to the terms of this Indenture
or the Debt Securities, or to add to the rights of the hollers of Debt
Securities.

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

                  Any supplemental indenture authorized by the provisions of
this Section 9.01 may be executed by the Company and the Trustee without the
consent of the holders of any of the Debt Securities at the time outstanding,
notwithstanding any of the provisions of Section 9.02.

         SECTION 9.02. Supplemental Indentures with Consent of Securityholders.

                  With the consent (evidenced as provided in Section 7.01) of
the holders of not less than a majority in aggregate principal amount of the
Debt Securities at the time outstanding affected by such supplemental indenture
(voting as a class), the Company, when authorized by a Board Resolution, 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, then in effect, applicable to indentures qualified
thereunder) for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture or of modifying in any manner the rights of the holders
of the Debt Securities; provided, however, that no such supplemental indenture
shall without such consent of the holders of each Debt Security then outstanding
and affected thereby (i) extend the fixed maturity of any Debt Security, or
reduce the principal amount thereof or any premium thereon, or reduce the rate
or extend the time of payment of interest thereon, or reduce any amount payable
on redemption thereof or make the principal thereof or any interest or premium
thereon payable in any coin or currency other than that provided in the Debt
Securities, or impair or affect the right of any Securityholder to institute
suit for payment thereof or impair the right of repayment, if any, at the option
of the holder, or (ii) reduce the aforesaid percentage of Debt Securities the
holders of which are required to consent to any such supplemental indenture; and
provided, further, that if the Debt Securities are held by the Trust or a
trustee of such trust, such supplemental indenture shall not be effective until
the holders of a majority in liquidation preference of the Trust Securities
shall have consented to such supplemental indenture; provided, further, that if
the consent of the Securityholder of each outstanding Debt Security is required,
such supplemental indenture shall not be effective until each holder of the
Trust Securities shall have consented to such supplemental indenture.

                                      -47-
<PAGE>

                  Upon the request of the Company accompanied by a Board
Resolution authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Securityholders
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.

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

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

         SECTION 9.03. Effect of Supplemental Indentures.

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

         SECTION 9.04. Notation on Debt Securities.

                  Debt Securities authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article IX may bear a notation as to any matter provided for in such
supplemental indenture. If the Company or the Trustee shall so determine, new
Debt Securities 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 and executed by the Company,
authenticated by the Trustee or the Authenticating Agent and delivered in
exchange for the Debt Securities then outstanding.

         SECTION 9.05. Evidence of Compliance of Supplemental Indenture to be
furnished to Trustee.

                  The Trustee, subject to the provisions of Sections 6.01 and
6.02, shall, in addition to the documents required by Section 14.06, receive an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant hereto complies with the requirements
of this Article IX. The Trustee shall receive an Opinion of

                                      -48-
<PAGE>

Counsel as conclusive evidence that any supplemental indenture executed pursuant
to this Article IX is authorized or permitted by, and conforms to, the terms of
this Article IX and that it is proper for the Trustee under the provisions of
this Article IX to join in the execution thereof.

                                    ARTICLE X

                            REDEMPTION OF SECURITIES

         SECTION 10.01. Optional Redemption.

                  At any time the Company shall have the right, subject to the
receipt by the Company of prior approval from the Federal Reserve, if then
required under applicable capital guidelines or policies of the Federal Reserve,
to redeem the Debt Securities, in whole or in part, on any January 7, April 7,
July 7 or October 7 on or after January 7, 2009 (the "Redemption Date"), at the
Redemption Price.

         SECTION 10.02. Special Event Redemption.

                  If a Special Event shall occur and be continuing, the Company
shall have the right, subject to the receipt by the Company of prior approval
from the Federal Reserve if then required under applicable capital guidelines or
policies of the Federal Reserve, to redeem the Debt Securities, in whole or in
part, at any time within 90 days following the occurrence of such Special Event
(the "Special Redemption Date"), at the Special Redemption Price.

         SECTION 10.03. Notice of Redemption; Selection of Debt Securities.

                  In case the Company shall desire to exercise the right to
redeem all, or, as the case may be, any part of the Debt Securities, it shall
fix a date for redemption and shall mail a notice of such redemption at least 30
and not more than 60 days prior to the date fixed for redemption to the holders
of Debt Securities so to be redeemed as a whole or in part at their last
addresses as the same appear on the Debt Security Register. Such mailing shall
be by first class mail. The notice if mailed in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the holder
receives such notice. In any case, failure to give such notice by mail or any
defect in the notice to the holder of any Debt Security designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Debt Security.

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

                                      -49-
<PAGE>

Debt Security or Debt Securities in principal amount equal to the unredeemed
portion thereof will be issued.

                  Prior to 10:00 a.m. New York City time on the Redemption Date
or the Special Redemption Date specified in the notice of redemption given as
provided in this Section, the Company will deposit with the Trustee or with one
or more Paying Agents an amount of money sufficient to redeem on the redemption
date all the Debt Securities so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption.

                  The Company will give the Trustee notice not less than 45 nor
more than 60 days prior to the redemption date as to the redemption price at
which the Debt Securities are to be redeemed and the aggregate principal amount
of Debt Securities to be redeemed and the Trustee shall select, in such manner
as in its sole discretion it shall deem appropriate and fair, the Debt
Securities or portions thereof (in integral multiples of $1,000) to be redeemed.

         SECTION 10.04. Payment of Debt Securities Called for Redemption.

                  If notice of redemption has been given as provided in Section
10.03, the Debt Securities or portions of Debt Securities with respect to which
such notice has been given shall become due and payable on the Redemption Date
or the Special Redemption Date (as the case may be) and at the place or places
stated in such notice at the applicable redemption price, together with interest
accrued to the date fixed for redemption, and on and after said Redemption Date
or the Special Redemption Date (unless the Company shall default in the payment
of such Debt Securities at the redemption price, together with interest accrued
to said date) interest on the Debt Securities or portions of Debt Securities so
called for redemption shall cease to accrue. On presentation and surrender of
such Debt Securities at a place of payment specified in said notice, such Debt
Securities or the specified portions thereof shall be paid and redeemed by the
Company at the applicable redemption price, together with interest accrued
thereon to the Redemption Date or the Special Redemption Date (as the case may
be).

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

                                   ARTICLE XI

                CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

         SECTION 11.01. Company May Consolidate, etc., on Certain Terms.

                  Nothing contained in this Indenture or in the Debt Securities
shall prevent any consolidation or merger of the Company with or into any other
corporation or corporations (whether or not affiliated with the Company) or
successive consolidations or mergers in which the Company or its successor or
successors shall be a party or parties, or shall prevent any sale, conveyance,
transfer or other disposition of the property or capital stock of the Company or
its successor or successors as an entirety, or substantially as an entirety, to
any other corporation

                                      -50-
<PAGE>

(whether or not affiliated with the Company, or its successor or successors)
authorized to acquire and operate the same; provided, however, that the Company
hereby covenants and agrees that, upon any such consolidation, merger (where the
Company is not the surviving corporation), sale, conveyance, transfer or other
disposition, the due and punctual payment of all payments due on all of the Debt
Securities in accordance with their terms, 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, shall be expressly
assumed by supplemental indenture reasonably satisfactory in form to the Trustee
executed and delivered to the Trustee by the entity formed by such
consolidation, or into which the Company shall have been merged, or by the
entity which shall have acquired such property or capital stock.

         SECTION 11.02. Successor Entity to be Substituted.

                  In case of any such consolidation, merger, sale, conveyance,
transfer or other disposition and upon the assumption by the successor entity,
by supplemental indenture, executed and delivered to the Trustee and reasonably
satisfactory in form to the Trustee, of the due and punctual payment of the
principal of and premium, if any, and interest on all of the Debt Securities and
the due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed or observed by the Company, such
successor entity shall succeed to and be substituted for the Company, with the
same effect as if it had been named herein as the Company, and thereupon the
predecessor entity shall be relieved of any further liability or obligation
hereunder or upon the Debt Securities. Such successor entity thereupon may cause
to be signed, and may issue either in its own name or in the name of the
Company, any or all of the Debt Securities issuable hereunder which theretofore
shall not have been signed by the Company and delivered to the Trustee or the
Authenticating Agent; and, upon the order of such successor entity instead of
the Company and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee or the Authenticating Agent shall authenticate
and deliver any Debt Securities which previously shall have been signed and
delivered by the officers of the Company, to the Trustee or the Authenticating
Agent for authentication, and any Debt Securities which such successor entity
thereafter shall cause to be signed and delivered to the Trustee or the
Authenticating Agent for that purpose. All the Debt Securities so issued shall
in all respects have the same legal rank and benefit under this Indenture as the
Debt Securities theretofore or thereafter issued in accordance with the terms of
this Indenture as though all of such Debt Securities had been issued at the date
of the execution hereof.

         SECTION 11.03. Opinion of Counsel to be Given to Trustee.

                  The Trustee, subject to the provisions of Sections 6.01 and
6.02, shall receive, in addition to the Opinion of Counsel required by Section
9.05, an Opinion of Counsel as conclusive evidence that any consolidation,
merger, sale, conveyance, transfer or other disposition, and any assumption,
permitted or required by the terms of this Article XI complies with the
provisions of this Article XI.

                     SATISFACTION AND DISCHARGE OF INDENTURE

         SECTION 12.01. Discharge of Indenture.

                  When (a) the Company shall deliver to the Trustee for
cancellation all Debt Securities theretofore authenticated (other than any Debt
Securities which shall have been destroyed, lost or stolen and which shall have
been replaced or paid as provided in Section 2.06) and not theretofore canceled,
or (b) all the Debt Securities not theretofore canceled or 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 with the
Trustee, in trust, funds, which shall be immediately due and payable, sufficient
to pay at maturity or upon redemption all of the Debt Securities (other than any
Debt Securities which shall have been destroyed, lost or stolen and which shall
have been replaced or paid as provided in Section 2.06) not theretofore canceled
or delivered to the Trustee for cancellation, including principal and premium,
if any, and interest due or to become due to such date of maturity or redemption

the payment of principal of, and premium, if any, or interest on the Debt
Securities (1) theretofore repaid to the Company in accordance with the
provisions of Section 12.04, or (2) paid to any state or to the District of
Columbia pursuant to its unclaimed property or similar laws, and if in the case
of either clause (a) or clause (b) the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company, then this Indenture shall
cease to be of further effect except for the provisions of Sections 2.05, 2.06,
3.01, 3.02, 3.04, 6.06, 6.09 and 12.04 hereof, which shall survive until such
Debt Securities shall mature or are redeemed, as the case may be, and are paid.
Thereafter, Sections 6.06, 6.09 and 12.04 shall survive, and the Trustee, on
demand of the Company accompanied by an Officers' Certificate and an Opinion of
Counsel, each stating that all conditions precedent herein provided for relating
to the satisfaction and discharge of this Indenture have been complied with, and
at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture, the Company,
however, hereby agreeing to reimburse the Trustee for any costs or expenses
thereafter reasonably and properly incurred by the Trustee in connection with
this Indenture or the Debt Securities.

         SECTION 12.02. Deposited Moneys to be Held in Trust by Trustee.

                  Subject to the provisions of Section 12.04, all moneys
deposited with the Trustee pursuant to Section 12.01 shall be held in trust and
applied by it to the payment, either directly or through any Paying Agent
(including the Company if acting as its own Paying Agent), to the holders of the
particular Debt Securities for the payment of which such moneys have been
deposited with the Trustee, of all sums due and to become due thereon for
principal, and premium, if any, and interest.

                  Upon the satisfaction and discharge of this Indenture, all
moneys then held by any Paying Agent of the Debt Securities (other than the
Trustee) shall, upon demand of the Company, be repaid to the Company or paid to
the Trustee, and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.

         SECTION 12.04. Return of Unclaimed Moneys.

                  Any moneys deposited with or paid to the Trustee or any Paying
Agent for payment of the principal of, and premium, if any, or interest on Debt
Securities and not applied but remaining unclaimed by the holders of Debt
Securities for two years after the date upon which the principal of, and
premium, if any, or interest on such Debt Securities, as the case may be, shall
have become due and payable, shall be repaid to the Company by the Trustee or
such Paying Agent on written demand; and the holder of any of the Debt
Securities shall thereafter look only to the Company for any payment which such
holder may be entitled to collect and all liability of the Trustee or such
Paying Agent with respect to such moneys shall thereupon cease.

         SECTION 14.11. Assignment.

                  Subject to Article XI, the Company will have the right at all
times to assign any of its 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 will remain liable for all such
obligations. Subject to the foregoing, this Indenture is binding upon and inures
to the benefit of the parties hereto and their respective successors and
assigns. This Indenture may not otherwise be assigned by the parties thereto.

         SECTION 14.12. Acknowledgment of Rights.

                  The Company acknowledges that, with respect to any Debt
Securities held by the Trust or the Institutional Trustee of the Trust, if the
Institutional Trustee of the Trust fails to enforce its rights under this
Indenture as the holder of Debt Securities held as the assets of the Trust after
the holders of a majority in Liquidation Amount of the Capital Securities of the
Trust have so directed in writing such Institutional Trustee, a holder of record
of such Capital Securities may to the fullest extent permitted by law institute
legal proceedings directly against the Company to enforce such Institutional
Trustee's rights under this Indenture without first instituting any legal
proceedings against such Institutional Trustee or any other Person.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Company to pay
interest (or premium, if any) or principal on the Debt Securities on the date
such interest (or premium, if any) or principal is otherwise due and payable (or
in the case of redemption, on the redemption date), the Company acknowledges
that a holder of record of Capital Securities of the Trust may directly
institute a proceeding against the Company for enforcement of payment to such
holder directly of the principal of (or premium, if any) or interest on the Debt
Securities having an aggregate principal amount equal to the aggregate
Liquidation Amount of the Capital Securities of such holder on or after the
respective due date specified in the Debt Securities.

                                   ARTICLE XV

                        SUBORDINATION OF DEBT SECURITIES

         SECTION 15.01. Agreement to Subordinate.

                  The Company covenants and agrees, and each holder of Debt
Securities issued hereunder and under any supplemental indenture (the
"Additional Provisions") by such Securityholder's acceptance thereof likewise
covenants and agrees, that all Debt Securities shall be issued subject to the
provisions of this Article XV; and each holder of a Debt Security, 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 payments due on all Debt
Securities issued hereunder and under any Additional Provisions 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 Indebtedness of the
Company, whether outstanding at the date of this Indenture or thereafter
incurred.

                                      -56-
<PAGE>

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

         SECTION 15.02. Default on Senior Indebtedness.

                  In the event and during the continuation of any default by the
Company in the payment of principal, premium, interest or any other payment due
on any Senior Indebtedness of the Company following any applicable grace period,
or in the event that the maturity of any Senior Indebtedness of the Company has
been accelerated because of a default, and such acceleration has not been
rescinded or canceled and such Senior Indebtedness has not been paid in full,
then, in either case, no payment shall be made by the Company with respect to
the payments due on the Debt Securities.

                  In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee when such payment is prohibited by the
preceding paragraph of this Section 15.02, such payment shall, subject to
Section 15.06, 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.

         SECTION 15.03. Liquidation; Dissolution; Bankruptcy.

                  Upon any payment by the Company or distribution of assets of
the Company of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution or winding- up or liquidation or
reorganization of the Company, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, all 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 the Debt Securities; 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 Securityholders or the Trustee would be
entitled to receive from the Company, except for the provisions of this Article
XV, 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 Securityholders 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 Securityholders.

                                      -57-
<PAGE>

                  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, as their respective interests may appear, as calculated by
the Company, for application to the payment of all Senior Indebtedness of the
Company 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.

                  For purposes of this Article XV, 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 XV with respect
to the Debt Securities to the payment of all Senior Indebtedness of the Company,
that may at the time be outstanding, provided, that (a) such Senior Indebtedness
is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (b) 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, 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 of this Indenture shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the purposes
of this Section 15.03 if such other corporation shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Article IX of this Indenture. Nothing in Section 15.02 or in this Section
15.03 shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 6.06 of this Indenture.

         SECTION 15.04. Subrogation.

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

                                      -58-
<PAGE>

                  Nothing contained in this Article XV or elsewhere in this
Indenture, any Additional Provisions or in the Debt Securities 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 the Debt Securities, the
obligation of the Company, which is absolute and unconditional, to pay to the
holders of the Debt Securities all payments on the Debt Securities as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the holders of the Debt
Securities and creditors of the Company, other than the holders of Senior
Indebtedness of the Company, nor shall anything herein or therein prevent the
Trustee or the holder of any Debt Security from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, under this Article XV of the holders of such Senior
Indebtedness in respect of cash, property or securities of the Company received
upon the exercise of any such remedy.

                  Upon any payment or distribution of assets of the Company
referred to in this Article XV, the Trustee, subject to the provisions of
Article VI of this Indenture, and the Securityholders 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 the Securityholders, for
the purposes of ascertaining the Persons entitled to participate in such
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article XV.

         SECTION 15.05. Trustee to Effectuate Subordination.

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

         SECTION 15.06. Notice by the Company.

                  The Company shall give prompt written notice to a Responsible
Officer of the Trustee at the Principal Office of the Trustee of any fact known
to the Company that would prohibit the making of any payment of moneys to or by
the Trustee in respect of the Debt Securities pursuant to the provisions of this
Article XV. Notwithstanding the provisions of this Article XV or any other
provision of this Indenture or any Additional Provisions, the Trustee shall not
be charged with knowledge of the existence of any facts that would prohibit the
making of any payment of moneys to or by the Trustee in respect of the Debt
Securities pursuant to the provisions of this Article XV, unless and until a
Responsible Officer of the Trustee at the Principal Office 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 Article VI of
this Indenture, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall not have received the notice
provided for in this Section 15.06 at least two Business Days prior to the date
upon which by the terms hereof any money may become payable for any

                                      -59-
<PAGE>

purpose (including, without limitation, the payment of the principal of (or
premium, if any) or interest on any Debt Security), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purposes for which
they were received, and shall not be affected by any notice to the contrary that
may be received by it within two Business Days prior to such date.

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

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

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

                  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 XV, and
no implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture or any Additional Provisions
against the Trustee. The Trustee shall not owe or be deemed to owe any fiduciary
duty to the holders of such Senior Indebtedness and, subject to the provisions
of Article VI of this Indenture, the Trustee shall not be liable to any holder
of such Senior Indebtedness if it shall pay over or deliver to Securityholders,
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 XV or otherwise.

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

         SECTION 15.08. Subordination May Not Be Impaired.

                  No right of any present or future holder of any Senior
Indebtedness 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,

                                      -60-
<PAGE>

provisions and covenants of this Indenture, regardless of any knowledge thereof
that any such holder may have or otherwise be charged with.

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

                  Wells Fargo Bank, National Association, in its capacity as
Trustee, hereby accepts the trusts in this Indenture declared and provided, upon
the terms and conditions herein above set forth.

               Form of Junior Subordinated Debt Security due 2034

                                       of

                            Pinnacle Bancshares, Inc.

                  Pinnacle Bancshares, Inc., a bank holding company incorporated
in Delaware (the "Company"), for value received promises to pay to Wells Fargo
Bank, National Association, not in its individual capacity but solely as
Institutional Trustee for Pinnacle Capital Trust I, a Delaware statutory trust
(the "Holder"), or registered assigns, the principal sum of Three Million Ninety
Three Thousand Dollars on January 7, 2034 and to pay interest on said principal
sum from December 22, 2003, or from the most recent interest payment date (each
such date, an "Interest Payment Date") to which interest has been paid or duly
provided for, quarterly (subject to deferral as set forth herein) in arrears on
January 7, April 7, July 7 and October 7 of each year commencing January 7,
2004, at a variable per annum rate equal to LIBOR (as defined in the Indenture)
plus 2.85% (the "Interest Rate") until the principal hereof shall have become
due and payable, and on any overdue principal and (without duplication and to
the extent that payment of such interest is enforceable under applicable law) on
any overdue installment of interest at an annual rate equal to the Interest Rate
in effect for each such Extension Period compounded quarterly. The amount of
interest payable on any Interest Payment Date shall be computed on the basis of
a 360-day year and the actual number of days elapsed in the relevant interest
period. Notwithstanding anything to the contrary contained herein, if any
Interest Payment Date, other than on the Maturity Date, any Redemption Date or
the Special Redemption Date, falls on a day that is not a Business Day, then any
interest payable will be paid on, and such Interest Payment Date will be moved
to, the next succeeding Business Day, and additional interest will accrue for
each day that such payment is delayed as a result thereof. If the Maturity Date,
any Redemption Date or the Special Redemption date falls on a day that is not a
Business Day, then the principal, premium, if any, and/or interest payable on
such date will be paid on the next succeeding Business Day, and no additional
interest will accrue in respect of such payment made on such next succeeding
Business Day. The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Debt Security (or one or more
Predecessor Securities, as defined in said Indenture) is registered at the close
of business on the regular record date for such interest installment, except
that interest and any Deferred Interest payable on the Maturity Date shall be
paid to the Person to whom principal is paid. Any such interest installment not
punctually paid or duly provided for shall forthwith cease to be payable to the
registered holders on such regular record date and may be paid to the Person in
whose name this Debt Security (or one or more Predecessor Debt Securities) is
registered at the close of business on a special record date to be fixed by the
Trustee for the payment of such defaulted interest, notice whereof shall be
given to the registered holders of the Debt Securities not less than 10 days
prior to such special record date, all as more fully provided in the Indenture.
The principal of and interest on this Debt Security shall be payable at the
office or agency of the Trustee (or other Paying Agent appointed by the Company)
maintained for that purpose in any coin or currency of the United States of
America that at the time of payment is legal tender for payment of public and
private debts; provided, however, that payment of interest may be made at the
option of the Company by check mailed to the registered holder at such address
as shall appear in the Debt Security Register or by wire transfer to an account
appropriately designated by the holder hereof. Notwithstanding the

                                      A-3
<PAGE>

foregoing, so long as the holder of this Debt Security is the Institutional
Trustee, the payment of the principal of and interest on this Debt Security will
be made in immediately available funds at such place and to such account as may
be designated by the Trustee.

                  Upon submission of Notice (as defined in the Indenture) and so
long as no Event of Default has occurred and is continuing, the Company shall
have the right, from time to time and without causing an Event of Default, to
defer payments of interest on the Debt Securities by extending the interest
payment period on the Debt Securities at any time and from time to time during
the term of the Debt Securities, for up to 20 consecutive quarterly periods
(each such extended interest payment period, an "Extension Period"), during
which Extension Period no interest shall be due and payable (except any
Additional Interest that may be due and payable). During any Extension Period,
interest will continue to accrue on the Debt Securities, and interest on such
accrued interest (such accrued interest and interest thereon referred to herein
as "Deferred Interest") will accrue at an annual rate equal to the Interest Rate
in effect for each such Extension Period, compounded quarterly from the date
such Deferred Interest would have been payable were it not for the Extension
Period, to the extent permitted by law. No Extension Period may end on a date
other than an Interest Payment Date. At the end of any such Extension Period the
Company shall pay all Deferred Interest then accrued and unpaid on the Debt
Securities; provided, however, that no Extension Period may extend beyond the
Maturity Date and provided, further, however, during any such Extension Period,
the Company may not (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
the Company's capital stock or (ii) make any payment on or repay, repurchase or
redeem any debt securities of the Company that rank pari passu in all respects
with or junior in interest to the Debt Securities (other than (a) repurchases,
redemptions or other acquisitions of shares of capital stock of the Company (A)
in connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of one or more employees, officers,
directors or consultants, (B) in connection with a dividend reinvestment or
stockholder stock purchase plan or (C) in connection with the issuance of
capital stock of the Company (or securities convertible into or exercisable for
such capital stock), as consideration in an acquisition transaction entered into
prior to the applicable Extension Period, (b) as a result of any exchange or
conversion of any class or series of the Company's capital stock (or any capital
stock of a subsidiary of the Company) for any class or series of the Company's
capital stock or of any class or series of the Company's indebtedness for any
class or series of the Company's capital stock, (c) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the conversion or
exchange provisions of such capital stock or the security being converted or
exchanged, (d) any declaration of a dividend in connection with any
stockholder's rights plan, or the issuance of rights, stock or other property
under any stockholder's rights plan, or the redemption or repurchase of rights
pursuant thereto, or (e) any dividend in the form of stock, warrants, options or
other rights where the dividend stock or the stock issuable upon exercise of
such warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock). Prior
to the termination of any Extension Period, the Company may further extend such
period, provided, that such period together with all such previous and further
consecutive extensions thereof shall not exceed 20 consecutive quarterly
periods, or extend beyond the Maturity Date. Upon the termination of any
Extension Period and upon the payment of all Deferred Interest, the Company may
commence a new Extension Period, subject to the foregoing requirements. No
interest or Deferred Interest shall be due and payable during an Extension
Period, except at the end thereof,

                                      A-4
<PAGE>

but Deferred Interest shall accrue upon each installment of interest that would
otherwise have been due and payable during such Extension Period until such
installment is paid. The Company must give the Trustee notice of its election to
begin such Extension Period at least one Business Day prior to the earlier of
(i) the next succeeding date on which interest on the Debt Securities would have
been payable except for the election to begin such Extension Period or (ii) the
date such interest is payable, but in any event not later than the related
regular record date.

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

                  The Company waives demand, presentment for payment, notice of
nonpayment, notice of protest, and all other notices.

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

                  The provisions of this Debt Security are continued on the
reverse side hereof and such continued provisions shall for all purposes have
the same effect as though fully set forth at this place.

                          [FORM OF REVERSE OF SECURITY]

                  This Debt Security is one of a duly authorized series of Debt
Securities of the Company, all issued or to be issued pursuant to an Indenture
(the "Indenture"), dated as of December 22, 2003, duly executed and delivered
between the Company and Wells Fargo Bank, National Association, as Trustee (the
"Trustee"), to which Indenture and all indentures supplemental thereto reference
is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and
the holders of the Debt Securities (referred to herein as the "Debt Securities")
of which this Debt Security is a part. The summary of the terms of this Debt
Security contained herein does not purport to be complete and is qualified by
reference to the Indenture.

                  Upon the occurrence and continuation of a Tax Event, an
Investment Company Event or a Capital Treatment Event (each a "Special Event"),
this Debt Security may become due and payable, in whole or in part, at any time,
within 90 days following the occurrence of such Tax Event, Investment Company
Event or Capital Treatment Event (the "Special Redemption Date"), as the case
may be, at the Special Redemption Price. The Company shall also have the right
to redeem this Debt Security at the option of the Company, in whole or in part,
on any January 7, April 7, July 7 or October 7 on or after January 7, 2009 (a
"Redemption Date"), at the Redemption Price.

                  Any redemption pursuant to the preceding paragraph will be
made, subject to the receipt by the Company of prior approval from the Board of
Governors of the Federal Reserve System (the "Federal Reserve") if then required
under applicable capital guidelines or policies of the Federal Reserve, upon not
less than 30 days' nor more than 60 days' notice. If the Debt Securities are
only partially redeemed by the Company, the Debt Securities will be redeemed pro
rata or by lot or by any other method utilized by the Trustee.

                  "Redemption Price" means 100% of the principal amount of the
Debt Securities being redeemed plus accrued and unpaid interest on such Debt
Securities to the Redemption Date or, in the case of a redemption due to the
occurrence of a Special Event, to the Special Redemption Date if such Special
Redemption Date is on or after January 7, 2009.

                  "Special Redemption Price" means (1) if the Special Redemption
Date is before January 7, 2009, One Hundred Five Percent (105%) of the principal
amount to be redeemed plus any accrued and unpaid interest thereon to the date
of such redemption and (2) if the Special Redemption Date is on or after January
7, 2009 the Redemption Price for such Special Redemption Date.

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

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

                                      A-7
<PAGE>

                  The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Debt Securities at the time outstanding
affected thereby, as specified in the Indenture, to execute supplemental
indentures for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Indenture or of any supplemental
indenture or of modifying in any manner the rights of the holders of the Debt
Securities; provided, however, that no such supplemental indenture shall, among
other things, without the consent of the holders of each Debt Security then
outstanding and affected thereby (i) extend the fixed maturity of the Debt
Securities, or reduce the principal amount thereof or any redemption premium
thereon, or reduce the rate or extend the time of payment of interest thereon,
or make payments due on the Debt Securities payable in any coin or currency
other than that provided in the Debt Securities, or impair or affect the right
of any holder of Debt Securities to institute suit for the payment thereof, or
(ii) reduce the aforesaid percentage of Debt Securities, the holders of which
are required to consent to any such supplemental indenture. The Indenture also
contains provisions permitting the holders of a majority in aggregate principal
amount of the Debt Securities at the time outstanding, on behalf of all of the
holders of the Debt Securities, to waive any past default in the performance of
any of the covenants contained in the Indenture, or established pursuant to the
Indenture, and its consequences, except a default in payments due on any of the
Debt Securities. Any such consent or waiver by the registered holder of this
Debt Security (unless revoked as provided in the Indenture) shall be conclusive
and binding upon such holder and upon all future holders and owners of this Debt
Security and of any Debt Security issued in exchange herefor or in place hereof
(whether by registration of transfer or otherwise), irrespective of whether or
not any notation of such consent or waiver is made upon this Debt Security.

                  No reference herein to the Indenture and no provision of this
Debt Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay all payments due on this
Debt Security at the time and place and at the rate and in the money herein
prescribed.

                  As provided in the Indenture and subject to certain
limitations herein and therein set forth, this Debt Security is transferable by
the registered holder hereof on the Debt Security Register of the Company, upon
surrender of this Debt Security for registration of transfer at the office or
agency of the Trustee in Wilmington, Delaware accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company or the
Trustee duly executed by the registered holder hereof or such holder's attorney
duly authorized in writing, and thereupon one or more new Debt Securities of
authorized denominations and for the same aggregate principal amount will be
issued to the designated transferee or transferees. No service charge will be
made for any such registration of transfer, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
relation thereto.

                  Prior to due presentment for registration of transfer of this
Debt Security, the Company, the Trustee, any Authenticating Agent, any Paying
Agent, any transfer agent and the Debt Security registrar may deem and treat the
registered holder hereof as the absolute owner hereof (whether or not this Debt
Security shall be overdue and notwithstanding any notice of ownership or writing
hereon) for the purpose of receiving payment of or on account of the principal
hereof and interest due hereon and for all other purposes, and neither the
Company nor

                                      A-8
<PAGE>

the Trustee nor any Authenticating Agent nor any Paying Agent nor any transfer
agent nor any Debt Security registrar shall be affected by any notice to the
contrary.

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

                  The Debt Securities are issuable only in registered
certificated form without coupons. As provided in the Indenture and subject to
certain limitations herein and therein set forth, Debt Securities are
exchangeable for a like aggregate principal amount of Debt Securities of a
different authorized denomination, as requested by the holder surrendering the
same.

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

                  THE LAW OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE
AND THE DEBT SECURITIES, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES THEREOF.
