transferred, in whole but not in part, only to another nominee of the
Depositary, or to a successor Depositary selected or approved by the Issuer
or to a nominee of such successor Depositary.

         (c)    If at any time the Depositary notifies the Issuer that it is
unwilling or unable to continue as Depositary or if at any time the
Depositary for such series shall no longer be registered or in good standing
under the Securities Exchange Act of 1934, as amended, or other applicable
statute or regulation, and a successor Depositary for such series is not
appointed by the Issuer within 90 days after the Issuer receives such notice
or becomes aware of such condition, as the case may be, the Issuer will
execute, and, subject to Section 2.8 of the Indenture, the Trustee, upon
written notice from the Issuer, will authenticate and deliver the Debentures
in definitive registered form, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global
Debenture in exchange for such Global Debenture. In addition, the Issuer may
at any time determine that the Debentures shall no longer be represented by
a Global Debenture. In such event the Issuer will execute, and subject to
Section 2.8 of the Indenture, the Trustee, upon receipt of an Officers'
Certificate evidencing such determination by the Issuer, will authenticate
and deliver the Debentures in definitive registered form, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Debenture in exchange for such Global Debenture. Upon
the exchange of the Global Debenture for such Debentures in definitive
registered form, in authorized denominations, the Global Debenture shall be
canceled by the Trustee. Such Debentures in definitive registered form
issued in exchange for the Global Debenture shall be registered in such
names and in such authorized denominations as the Depositary, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Debentures to the
Depositary for delivery to the Persons in whose names such Debentures are so
registered.

SECTION 2.5 Interest

         (a)    Each Debenture will bear interest at the rate of     % per
                                                               ----
annum (the "Coupon Rate") from the original date of issuance until the
principal thereof becomes due and payable, and on any overdue principal and
(to the extent that payment of such interest is enforceable under applicable
law) on any overdue installment of interest, at the Coupon Rate, compounded
quarterly, payable (subject to the provisions of Article IV) quarterly in
arrears on          ,           ,            and           of each year
           ---------  ----------  ----------     ---------
(each, an "Interest Payment Date," commencing on               , 2002, to
                                                 --------------
the Person in

                                     4

<PAGE>
<PAGE>

whose name such Debenture or any predecessor Debenture is registered, at the
close of business on the regular record date for such interest installment,
which, in respect of any Debentures of which the Property Trustee is the
Holder or a Global Debenture, shall be the close of business on the Business
Day next preceding that Interest Payment Date. Notwithstanding the foregoing
sentence, if the Preferred Securities are no longer in book-entry only form
or, except if the Debentures are held by the Property Trustee, the
Debentures are not represented by a Global Debenture, the regular record
date for such interest installment shall be the              day of the
                                                ------------
month in which the applicable Interest Payment Date occurs.

         (b)    The amount of interest payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months. Except as
provided in the following sentence, the amount of interest payable for any
period shorter than a full quarterly period for which interest is computed,
will be computed on the basis of the actual number of days elapsed in such a
90-day period. In the event that any date on which interest is payable on
the Debentures is not a Business Day, then payment of interest payable on
such date will be made on the next succeeding day which is a Business Day
(and without any interest or other payment in respect of any such delay),
except that, if such Business Day is in the next succeeding calendar year,
such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date.

         (c)    If, at any time while the Property Trustee is the Holder of
any Debentures, the Trust or the Property Trustee is required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States, or any other taxing
authority, then, in any case, the Issuer will pay as additional interest
("Additional Interest") on the Debentures held by the Property Trustee, such
additional amounts as shall be required so that the net amounts received and
retained by the Trust and the Property Trustee after paying such taxes,
duties, assessments or other governmental charges will be equal to the
amounts the Trust and the Property Trustee would have received had no such
taxes, duties, assessments or other governmental charges been imposed.

                    ARTICLE III. REDEMPTION OF THE DEBENTURES

SECTION 3.1 Special Event Redemption

         If (a) a Tax Event has occurred and is continuing and (i) the Issuer
has received a Redemption Tax Opinion, or (ii) the Regular Trustees shall
have been informed by tax counsel that a No Recognition Opinion cannot be
delivered to the Trust; or (b) an Investment Company Event has occurred and
is continuing, then, notwithstanding Section 3.2(a) but subject to Section
3.2(b) and Article XI of the Indenture, the Issuer shall have the right upon
not less than 30 days' nor more than 60 days' notice to the Holders of the
Debentures to redeem the Debentures, in whole or in part, for cash within 90
days following the occurrence of such Special Event (the "90 Day Period") at
a redemption price equal to 100% of the principal amount to be redeemed plus
any accrued and unpaid interest thereon to the date of such redemption (the
"Redemption Price"), provided that if at the time there is available to the
Issuer or the Trust the opportunity to eliminate, within the 90 Day Period,
the Special Event by taking some ministerial action ("Ministerial Action"),
such as filing a form or making an election, or pursuing some other similar
reasonable measure which has no adverse effect on the Issuer, the Trust or
the Holders of the Trust Securities issued by the Trust, the Issuer shall
pursue such Ministerial Action in lieu of redemption, and, provided, further,
that the Issuer shall have no right to redeem the Debentures while the Trust
is pursuing any Ministerial Action pursuant to its obligations under the
Declaration. The Redemption Price shall be paid prior to 12:00 noon, local
time, on the date of such redemption or such earlier time as the Issuer
determines, and the Issuer shall deposit with the Trustee an amount
sufficient to pay the Redemption Price by 10:00 a.m., local time, on the date
such Redemption Price is to be paid.

SECTION 3.2 Optional Redemption by Issuer

         (a)    Subject to the provisions of Section 3.2(b) and to the
provisions of Article XI of the Indenture, the Issuer shall have the right to
redeem the Debentures, in whole or in part, from time to time, on or after
         , 20  , at a redemption price equal to 100% of the principal amount

to be redeemed plus any accrued and unpaid interest thereon to the date of
such redemption (the "Optional Redemption Price"). Any redemption pursuant to
this paragraph will be made upon not less than 30 days' nor more than 60
days' notice to the Holder of the Debentures, at the Optional Redemption
Price. If the Debentures are only partially redeemed pursuant to this Section
3.2, the Debentures will be redeemed on a pro rata basis provided that if at
the time of redemption the Debentures are registered as a Global Debenture,
the Depositary shall determine, in accordance with its procedures, the
principal amount of such Debentures held by each Holder of Debentures to be
redeemed. The Optional Redemption Price shall be paid prior to 12:00 noon,
local time, on the date of such redemption or at such earlier time as the
Issuer determines and the Issuer shall deposit with the Trustee an amount
sufficient to pay the Optional Redemption Price by 10:00 a.m., local time, on
the date such Optional Redemption Price is to be paid.

         (b)    If a partial redemption of the Debentures would result in the
delisting of the Preferred Securities from any national securities exchange
or other organization on which the Preferred Securities are then listed, the
Issuer shall not be permitted to effect such partial redemption and may only
redeem the Debentures in whole.

SECTION 3.3 No Sinking Fund

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

                ARTICLE IV. EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1 Extension of Interest Payment Period

         The Issuer shall have the right, at any time and from time to time
during the term of the Debentures, to defer payments of interest by extending
the interest payment period of such Debentures for a period not exceeding 20
consecutive quarters (the "Extended Interest Payment Period"), during which
Extended Interest Payment Period no interest shall be due and payable;
provided that no Extended Interest Payment Period may extend beyond the
Maturity Date. To the extent permitted by applicable law, interest, the
payment of which has been deferred because of the extension of the interest
payment period pursuant to this Section 4.1, will bear interest thereon at
the Coupon Rate compounded quarterly for each quarter of the Extended
Interest Payment Period ("Compounded Interest"). At the end of the Extended
Interest Payment Period, the Issuer shall pay all interest accrued and unpaid
on the Debentures, including any Additional Interest and Compounded Interest
(together, "Deferred Interest") that shall be payable to the Holders of the
Debentures in whose names the Debentures are registered in the Security
Register on the first record date after the end of the Extended Interest
Payment Period. Prior to the termination of any Extended Interest Payment
Period, the Issuer may further extend such period, provided that such period
together with all such further extensions thereof shall not exceed 20
consecutive quarters. Upon the termination of any Extended Interest Payment
Period and upon the payment of all Deferred Interest then due, the Issuer may
commence a new Extended Interest Payment Period, subject to the foregoing
requirements. No interest shall be due and payable during an Extended
Interest Payment Period, except at the end thereof, but the Issuer may prepay
at any time all or any portion of the interest accrued during an Extended
Interest Payment Period.

apply during any Extended Interest Payment Period.

Debentures at the time the Issuer elects an Extended Interest Payment Period,
the Issuer shall give written notice to the Regular Trustees, the Property
Trustee and the Trustee of its election of such Extended Interest Payment
Period one Business Day before the earlier of (i) the next succeeding date on

other applicable self-regulatory organization or to Holders of the
Debentures, but in any event at least 2 Business Days before such record
date.

(a) or (b) of this Section 4.2 shall be counted as one of the 20 quarters
permitted in the maximum Extended Interest Payment Period permitted under
Section 4.1.

(without duplication and to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at
the same rate per annum compounded quarterly. The amount of interest payable
on any Interest Payment Date shall be computed on the basis of a 360-day year
of twelve 30-day months. In the event that any date on which interest is
payable on this Debenture is not a Business Day, then payment of interest
payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any
such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding

provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the person in whose name this Debenture (or one or more Predecessor
Securities, as defined in said Indenture) is registered at the close of
business on the regular record date for such interest installment, which shall
be the close of business on the Business Day next preceding such Interest
Payment Date. [IF PURSUANT TO THE PROVISIONS OF THE INDENTURE THE DEBENTURES

interest due on such Interest Payment Date, interest shall be paid to the
person in whose name this Debenture is registered at the close of business on
a subsequent record date (which shall not be less than five Business Days
prior to the date of payment of such defaulted interest) established by
notice given by mail by or on behalf of the Issuer to the Holder of this
Debenture not less than 15 days preceding such subsequent Record Date. The

currency of the United States of America that at the time is legal tender
for payment of public and private debts; provided, however, that payment of
interest may be made at the option of the Issuer by check mailed to the
registered Holder at such address as shall appear in the Security Register
or by wire transfer to an account maintained by the Holder. Notwithstanding
the foregoing, so long as the Holder of this Debenture is the Property
Trustee, the

payment of the principal of (and premium, if any) and interest on this
Debenture will be made at such place and to such account as may be
designated by the Property Trustee.

         The indebtedness evidenced by this Debenture 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 Debenture is
issued subject to the provisions of the Indenture with respect thereto. Each
Holder of this Debenture, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee on his or
her behalf to take such action as may be necessary or appropriate to

the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

         This Debenture shall not be entitled to any benefit under the

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

         This Debenture shall be governed by and construed in accordance with
the laws of the State of New York without regard to principles of conflict of
laws thereof.

                         (FORM OF REVERSE OF DEBENTURE)

         This Debenture is one of a duly authorized series of Securities of
the Issuer (herein sometimes referred to as the "Debentures"), specified in
the Indenture, all issued or to be issued in one or more series under and
pursuant to an Indenture dated as of             , 2002, duly executed and
                                     ------------
delivered between the Issuer and The Bank of New York, a New York banking
corporation, as Trustee (the "Trustee"), as supplemented by the First
Supplemental Indenture dated as of             , 2002, between the Issuer and
                                   ------------
the Trustee (the Indenture as so supplemented, the "Indenture"), to which
Indenture reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the Holders of the Debentures. By the terms of the
Indenture, the Debentures are issuable in series that may vary as to amount,
date of maturity, rate of interest and in other respects as provided in the
Indenture. This series of Debentures is limited in aggregate principal amount
as specified in said First Supplemental Indenture.

         The Issuer shall have the right to redeem this Debenture at the
option of the Issuer, without premium or penalty, in whole or in part at any
time on or after           , 20  , or at any time in certain circumstances
                 ----------    --
upon the occurrence of a Special Event, at a redemption price equal to 100%
of the principal amount plus any accrued but unpaid interest, to the date of
such redemption. Any redemption pursuant to this paragraph will be made upon
not less than 30 days' nor more than 60 days' notice. If the Debentures are
only partially redeemed by the Issuer pursuant to an Optional Redemption, the
Debentures will be redeemed pro rata.

         In the event of redemption of this Debenture in part only, a new
Debenture or Debentures of this series 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 Debentures may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the
Indenture.

         The Indenture contains provisions permitting the Issuer and the
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Debentures and other Indenture securities
of each series affected at the time Outstanding and affected (voting as one
class), as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner

                                       11

<PAGE>
<PAGE>

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
Debentures; provided, however, that the Company and the Trustee may not,
without the consent of the Holder of each Debenture then Outstanding and
affected thereby: (a) change the time of payment of the principal (or any
installment) of any Debenture, or reduce the principal amount thereof, or
reduce the rate or change the time of payment of interest thereon, or impair
the right to institute suit for the enforcement of any payment on any
Debenture when due or (b) reduce the percentage in principal amount of the
Debentures, the consent of whose Holders is required for any such
modification or for any waiver provided for in the Indenture. The Indenture
also contains provisions providing that prior to the acceleration of the
maturity of any Debenture or other securities outstanding under the
Indenture, the Holders of a majority in aggregate principal amount of
Debentures of and other Securities Outstanding under the Indenture with
respect to which a default or an Event of Default shall have occurred and be
continuing (voting as one class) may on behalf of the Holders of all such
affected Securities (including the Debentures) waive any past default and
its consequences, except a default or an Event of Default in respect of a
covenant or provision of the Indenture or of any Debenture or other Security
which cannot be modified or amended without the consent of the Holder of
each Debenture or other Security affected. Any such consent or waiver by the
registered Holder of this Debenture (unless revoked as provided in the
Indenture) shall be conclusive and binding upon such Holder and upon all
future Holders and owners of this Debenture and of any Debenture 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 Debenture.

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

         The Issuer shall have the right at any time during the term of the
Debentures and from time to time to extend the interest payment period of
such Debentures for up to 20 consecutive quarters (an "Extended Interest
Payment Period"), at the end of which period the Issuer shall pay all
interest then accrued and unpaid (together with interest thereon at the rate
specified for the Debentures to the extent that payment of such interest is
enforceable under applicable law). Before the termination of any such
Extended Interest Payment Period, the Issuer may further extend such Extended
Interest Payment Period, provided that such Extended Interest Payment Period
together with all such further extensions thereof shall not exceed 20
consecutive quarters. At the termination of any such Extended Interest
Payment Period and upon the payment of all accrued and unpaid interest and
any additional amounts then due, the Issuer may commence a new Extended
Interest Payment Period.

         As provided in the Indenture and subject to certain limitations
therein set forth, this Debenture is transferable by the registered Holder
hereof on the Security Register of the Issuer, upon surrender of this
Debenture for registration of transfer at the office or agency of the Trustee
in the City and State of New York accompanied by a written instrument or
instruments of transfer in form satisfactory to the Issuer or the Trustee
duly executed by the registered Holder hereof or his or her attorney duly
authorized in writing, and thereupon one or more new Debentures of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such transfer, but the Issuer 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
Debenture, the Issuer, the Trustee, any paying agent and the Security
Registrar may deem and treat the registered holder hereof as the absolute
owner hereof (whether or not this Debenture shall be overdue and
notwithstanding any notice of ownership or writing hereon made by anyone
other than the Security Registrar) for the purpose of

                                     12

receiving payment of or on account of the principal hereof and premium, if
any, and interest due hereon and for all other purposes, and neither the
Issuer nor the Trustee nor any paying agent nor any 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 Debenture, 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 Issuer 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.

         Debentures of this series so issued are issuable only in registered
form without coupons in denominations of $25 and any integral multiple
thereof. As provided in the Indenture and subject to certain limitations
herein and therein set forth, Debentures of this series so issued are
exchangeable for a like aggregate principal amount of Debentures of this
series in authorized denominations, as requested by the Holder surrendering
the same.

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