                                 DEBT SECURITIES

      2.1   DESIGNATION AND PRINCIPAL AMOUNT. There is hereby authorized one
series of Debt Securities, to be designated the "___% Junior Subordinated Debt

$__________, which amount shall be as set forth in any written orders of the
Company for the authentication and delivery of Junior Subordinated Debt
Securities pursuant to Section 2.1 of the Base Indenture and Section 7.1 hereof.
Additional Junior Subordinated Debt Securities without limitation as to amount,
and without the consent of the holders of the then Outstanding Junior
Subordinated Debt Securities, may also be authenticated and delivered in the
manner provided in Section 2.1 of the Base Indenture. Any such additional Junior
Subordinated Debt Securities will have the same Stated Maturity and other terms
as those initially issued.

      2.2   STATED MATURITY. The Stated Maturity of the Junior Subordinated Debt
Securities is ___________, 20__ which may be shortened or extended pursuant to
Section 2.12 of the Base Indenture.

      2.3   FORM AND PAYMENT; MINIMUM TRANSFER RESTRICTION.

            (a) The Junior Subordinated Debt Securities shall be issued to the
[holders] [Property Trustee] in fully registered definitive form without coupons

                                       6
<PAGE>

minimum denominations of $____ and integral multiples of $____ in excess
thereof. Principal and interest on the Junior Subordinated Debt Securities
issued in definitive form will be payable, the transfer of such Junior
Subordinated Debt Securities will be registrable and such Junior Subordinated
Debt Securities will be exchangeable for Junior Subordinated Debt Securities
bearing identical terms and provisions at the principal office of the Trustee;
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 Register. [Notwithstanding the foregoing, so long as the registered
holder of any Junior Subordinated Debt Securities is the Property Trustee, the
payment of the principal of and interest (including Additional Interest and
Additional Tax Sums, if any) on such Junior Subordinated Debt Securities held by
the Property Trustee will be made at such place, or by wire transfer of
immediately available funds to such account, as may be designated by the
Property Trustee.] The Register for the Junior Subordinated Debt Securities
shall be kept at the principal office of the Trustee and the Trustee is hereby
appointed registrar for the Junior Subordinated Debt Securities.

            (b) The Junior Subordinated Debt Securities may be transferred or
exchanged only in minimum denominations of $____ and integral multiples of $____
in excess thereof, and any attempted transfer, sale or other disposition of
Junior Subordinated Debt Securities in a denomination of less than $____ shall
be deemed to be void and of no legal effect whatsoever. Any such transferee
shall be deemed not to be the holder of such Junior Subordinated Debt Securities
for any purpose, including but not limited to the receipt of payments in respect
of such Junior Subordinated Debt Securities and such transferee shall be deemed
to have no interest whatsoever in such Junior Subordinated Debt Securities.

      2.4   EXCHANGE AND REGISTRATION OF TRANSFER OF JUNIOR SUBORDINATED DEBT
SECURITIES; RESTRICTIONS ON TRANSFERS; DEPOSITARY. [If distributed to holders of
Capital Securities pursuant to Section 8.2 of the Trust Agreement, the Junior
Subordinated Debt Securities will be issued to such holders in the same form as
the Capital Securities that such Junior Subordinated Debt Securities replace in
accordance with the following procedures:]

            (a) So long as Junior Subordinated Debt Securities are eligible for
book-entry settlement with the Depositary, or unless required by law, all
Junior Subordinated Debt Securities that are so eligible will be represented by
one or more Junior Subordinated Debt Securities in global form (a "Global Debt
Security") registered in the name of the Depositary or the nominee of the
Depositary. Except as provided in Section 2.4(c) below, beneficial owners of a
Global Debt Security shall not be entitled to have Definitive Debt Security
Certificates registered in their names, will not receive or be entitled to
receive physical delivery of Definitive Debt Security Certificates and will not
be registered holders of such Global Debt Securities.

            (b) The transfer and exchange of beneficial interests in Global Debt
Securities shall be effected through the Depositary in accordance with the
Indenture and the procedures and standing instructions of the Depositary and the
Trustee shall make


                                       7
<PAGE>

appropriate endorsements to reflect increases or decreases in principal amounts
of such Global Debt Securities.

            (c) Notwithstanding any other provisions of the Indenture (other
than the provisions set forth in this Section 2.4(c)), a Global Debt Security
may not be exchanged in whole or in part for Junior Subordinated Debt Securities
registered, and no transfer of a Global Debt Security may be registered, in the
name of any person other than the Depositary or a nominee thereof unless (i)
such Depositary (A) has notified the Company that it is unwilling or unable to
continue as Depositary for such Global Debt Security or (B) has ceased to be a
clearing agency registered as such under the Exchange Act and no successor
Depositary has been appointed by the Company within 90 days after its receipt of
such notice or its becoming aware of such ineligibility, (ii) there shall have
occurred and be continuing an Event of Default, or any event which after notice
or lapse of time or both would be an Event of Default under the Indenture, with
respect to such Debt Security, or (iii) the Company, in its sole discretion,
instructs the Trustee to exchange such Global Debt Security for a Junior
Subordinated Debt Security that is not a Global Debt Security (in which case
such exchange shall be effected by the Trustee).

            The Depositary shall be a clearing agency registered under the
Exchange Act. The Company initially appoints The Depository Trust Company to act
as Depositary with respect to the Global Debt Securities. Initially, any Global
Debt Securities shall be registered in the name of Cede & Co., as the nominee of
the Depositary, and deposited with the Trustee as custodian for Cede & Co.

            Definitive Junior Subordinated Debt Securities issued in exchange
for all or a part of a Global Debt Security pursuant to this Section 2.4(c)
shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee. Upon execution and authentication, the
Trustee shall deliver such definitive Junior Subordinated Debt Securities to the
person in whose names such definitive Junior Subordinated Debt Securities are so
registered.

            So long as Junior Subordinated Debt Securities are represented by
one or more Global Debt Securities, (i) the registrar for the Junior
Subordinated Debt Securities and the Trustee shall be entitled to deal with the
clearing agency for all purposes of the Indenture relating to such Global Debt
Securities as the sole holder of the Junior Subordinated Debt Securities
evidenced by such Global Debt Securities and shall have no obligations to the
holders of beneficial interests in such Global Debt Securities; and (ii) the
rights of the holders of beneficial interests in such Global Debt Securities
shall be exercised only through the clearing agency and shall be limited to
those established by law and agreements between such holders and the clearing
agency and/or the participants in the clearing agency.

            At such time as all interests in a Global Debt Security have been
paid, redeemed, exchanged, repurchased or canceled, such Global Debt Security
shall be, upon receipt thereof, canceled by the Trustee in accordance with
standing procedures and


                                       8
<PAGE>

instructions of the Depositary. At any time prior to such cancellation, if any
interest in a Global Debt Security is exchanged for definitive Junior
Subordinated Debt Securities, redeemed by the Company pursuant to Article III or
canceled, or transferred for part of a Global Debt Security, the principal
amount of such Global Debt Security shall, in accordance with the standing
procedures and instructions of the Depositary be reduced or increased, as the
case may be, and an endorsement shall be made on such Global Debt Security by,
or at the direction of, the Trustee to reflect such reduction or increase.

      2.5   INTEREST.

            (a) Each Junior Subordinated Debt Security will bear interest at the
rate of ___% per annum (the "Coupon Rate") from ___________, 20__ until the
principal thereof becomes due and payable, and will bear interest on any overdue
principal at the Coupon Rate and (to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at the
Coupon Rate ("Additional Interest"), compounded [semi-annually], payable
(subject to the provisions of Article IV) [semi-annually] in arrears on the 15th
day of [_______] and [_______] of each year (each, an "Interest Payment Date"),
commencing on ______ 15, 20__ to the Person in whose name such Junior
Subordinated Debt Security is registered, subject to certain exceptions, at the
close of business on the Record Date next preceding such Interest Payment Date.
The "Record Date" for payment of interest will be the Business Day next
preceding the Interest Payment Date, unless such Junior Subordinated Debt
Security is registered to a holder other than the Property Trustee or a nominee
of the Depositary, in which case the Record Date for payment of interest will be
the fifteenth calendar day preceding the applicable Interest Payment Date,
whether or not a Business Day. [Until liquidation, if any, of the Trust, each
Junior Subordinated Debt Security will be held in the name of the Property
Trustee in trust for the benefit of the holders of the Trust Securities.]

            (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. In the event that any
date on which interest is payable on the Junior Subordinated Debt Securities 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 next
preceding day which is a Business Day, in each case with the same force and
effect as if made on the date such payment was originally payable.

            (c) [The Company will also pay any Additional Tax Sums as additional
distributions on the Junior Subordinated Debt Securities if the Trust is
required to pay any additional taxes, duties or other governmental charges as a
result of a Tax Event.]

      2.6   [DIRECT ACTION. In addition to any right of Direct Action granted
under Section 3.8(e) of the Trust Agreement to the holders of Capital
Securities, if the Property Trustee fails to enforce its rights under the Trust
Agreement or the Indenture to the fullest


                                       9
<PAGE>

extent permitted by law and subject to the terms of the Trust Agreement and the
Indenture, then a holder of Capital Securities may directly institute a
proceeding against the Company to enforce the Property Trustee's rights under
the Trust Agreement or the Indenture without first instituting a legal
proceeding against the Property Trustee or any other person.]

      2.7   SUBORDINATION. The indebtedness evidenced by the Junior Subordinated
Debt Securities shall be, to the extent and in the manner set forth in the
Base Indenture, subordinate and junior in right of payment to the prior
payment in full of all Senior Indebtedness of the Company with respect to the
Junior Subordinated Debt Securities, and the Junior Subordinated Debt
Securities shall rank pari passu in right of payment with each other series
of Securities issued under the Indenture.

any time within 90 days after the occurrence of that Special Event, in whole but
not in part, at a redemption price (the "Special Event Redemption Price") equal

Price") equal to the Optional Redemption Make-Whole Amount plus accrued and
unpaid interest thereon to but excluding the redemption date.] [SECOND
ALTERNATIVE - The Company shall have the option to redeem the Junior
Subordinated Debt Securities at any time on or after _________, 20__, in whole

The Company will notify the Trustee of the


                                       10

amount of the redemption price promptly after the calculation thereof and the
Trustee will not be responsible for such calculation.]]

                      [EXTENSION OF INTEREST PAYMENT PERIOD

      4.1   EXTENSION OF INTEREST PAYMENT PERIOD. So long as no Event of Default
under Section 6.1 of the Base Indenture has occurred and is continuing, the
Company shall have the right, subject to the provisions of Section 2.10 of the
Base Indenture, at any time during the term of the Junior Subordinated Debt
Securities, from time to time to defer the payment of interest by extending the
interest payment period of such Junior Subordinated Debt Securities for a period
not exceeding 10 consecutive semi-annual periods (an "Extension Period"), during
which Extension Period the Company shall not have the right to make partial
payments of interest. No Extension Period shall end on a date other than an
Interest Payment Date or extend beyond the Stated Maturity of the Junior
Subordinated Debt Securities. To the extent permitted by applicable law,
interest, the payment of which has been deferred because of an Extension Period
imposed pursuant to this Section 4.1, will bear Additional Interest compounded
[semi-annually]. At the end of the Extension Period, the Company shall pay all
interest then accrued and unpaid on the Junior Subordinated Debt Securities,
including any Additional Interest and Additional Tax Sums, if applicable, to the
holders of the Junior Subordinated Debt Securities in whose names the Junior
Subordinated Debt Securities are registered in the Register on the first Record
Date preceding the end of the Extension Period. Before the termination of any
Extension Period, the Company may further extend such Extension Period, provided
that such period together with all such further extensions thereof shall not
exceed 10 consecutive [semi-annual] periods, or extend beyond the Stated
Maturity. At any time following the termination of any Extension Period and upon
the payment of any accrued and unpaid Additional Interest and Additional Tax
Sums, if applicable, then due, the Company may elect to begin a new Extension
Period, subject to the foregoing requirements. No interest shall be due and
payable during an Extension Period, except at the end thereof.

      During any such Extension Period, the Company shall 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 of principal of or interest on or repay, repurchase or redeem
any debt securities of the Company that rank on a parity with or junior to this
Debt Security or make any guarantee payments with respect to any guarantee by
the Company of the debt securities of any Subsidiary of the Company that by its
terms ranks on a parity with or junior to this Debt Security (other than (a)
dividends or distributions in Common Stock, (b) any declaration of a dividend in
connection with the implementation of a Rights Plan, the issuance of any Capital
Stock of the Company under any Rights Plan or the redemption or repurchase of

plans for its directors, officers, employees, consultants or advisors).

      4.2   NOTICE OF EXTENSION.

Junior Subordinated Debt Securities at the time the Company elects to begin or
extend an Extension Period, the Company shall give written notice to the
Property Trustee, the Administrative Trustees and the Trustee of its election to
begin or extend any Extension Period at least five Business Days prior to the
earlier of (i) the next succeeding date on which Distributions on the Capital
Securities issued by the Trust would have been payable but for the election to

of federal securities law, the date the Administrative Trustees are required to
give notice to any securities exchange or other applicable self-regulatory
organization or to holders of such Capital Securities of the record date or the
date such Distributions are payable, but in any event not less than five
Business Days prior to such record date. An Administrative Trustee shall give
notice of the Company's election to begin or extend an Extension Period to the
holders of such Capital Securities.

            (b) If the Property Trustee is not the only holder of the Junior
Subordinated Debt Securities at the time the Company elects to begin or extend
an Extension Period, the Company shall give the holders of the Junior
Subordinated Debt Securities, the Administrative Trustees and the Trustee
written notice of its election to begin or extend such Extension Period at least
10 Business Days prior to the earlier of (i) the next succeeding Interest
Payment Date or (ii) subject to applicable principles of federal securities law,
the date the Company is required to give notice of the record or payment date of
such interest payment to any applicable self-regulatory organization or to
holders of the Junior Subordinated Debt Securities.

            (c) The semi-annual period in which any notice is given pursuant to
paragraphs (a) or (b) of this Section 4.2 shall be counted as one of the 10
consecutive semi-annual periods permitted in the maximum Extension Period

      The interest so payable will, subject to certain exceptions provided in
the Indenture hereinafter referred to, be paid to the person in whose name this
Debt Security is registered at the close of business on the Record Date next

time following the termination of any Extension Period and upon the payment
of any accrued and unpaid Additional Interest and Additional Tax Sums, if

                            REVERSE OF DEBT SECURITY

      [As provided in and subject to the provisions in the Indenture, the
Company shall have the option to redeem the Debt Securities of this series
[FIRST ALTERNATIVE - OPTIONAL REDEMPTION - at any time, in whole but not in
part,] [SECOND ALTERNATIVE - OPTIONAL REDEMPTION - at any time on or after
_________, 20__, in whole or in part,] at the Optional Redemption Price. In
addition, if a Special Event shall occur and be continuing, the Company may
redeem the Debt Securities of this series at any time within 90 days after the
occurrence of that Special Event, in whole but not in part, at the Special Event
Redemption Price.]

      In the case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Debt Securities of this
series 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.

      Any consent or waiver by the Holder of this Debt Security given as
provided in the Indenture (unless effectively revoked as provided in the
Indenture) shall be conclusive and binding upon such Holder and upon all future
Holders of this Debt Security and of any Debt Security issued in exchange,
registration of transfer, or otherwise in lieu hereof irrespective of whether
any notation of such consent or waiver is made upon this Debt Security or such
other Debt Securities. 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 the principal of and
interest on this Debt Security, at the places, at the respective times, at the
rate and in the coin or currency herein prescribed.

      As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Debt Security may be registered on the Register
of the Debt Securities of this series upon surrender of this Debt Security for
registration of transfer at the offices maintained by the Company or its agent
for such purpose, duly endorsed by the Holder hereof or his attorney duly
authorized in writing, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Securities registrar duly executed by
the Holder hereof or his attorney duly authorized in writing, but without
payment of any charge other than a sum sufficient to reimburse the Company for
any tax or other governmental charge incident thereto. Upon any such
registration of transfer, a new Debt Security or Debt Securities of authorized
denomination or denominations for the same aggregate principal amount will be
issued to the transferee in exchange herefor.

      Prior to due presentment for registration of transfer of this Debt
Security, the Company, the Trustee, and any agent of the Company or the Trustee
may deem and treat the person in whose name this Debt Security shall be
registered upon the Register of the Debt Securities of this series as the
absolute owner of this Debt Security (whether or not this Debt Security shall be
overdue and notwithstanding any notation of ownership or other writing hereon)
for the purpose of receiving payment of or on account of the


                                       23

principal hereof and, subject to the provisions on the face hereof, interest due
hereon and for all other purposes; and neither the Company nor the Trustee nor
any such agent shall be affected by any notice to the contrary.

      No recourse shall be had for the payment of the principal of or 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 or any indenture supplemental
thereto, against any stockholder, officer, director or employee, as such, past,
present or future, of the Company or of any successor corporation, either
directly or through the Company, 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 a part of the
consideration for the issue hereof, expressly waived and released.

      The Company and, by acceptance of this Debt Security or a beneficial
interest in this Debt Security, each holder hereof and any person acquiring a
beneficial interest herein, agree that for United States federal, state and
local tax purposes it is intended that this Debt Security constitute
indebtedness.

      This Debt Security shall be deemed to be a contract made under the laws of
the State of New York (without regard to conflicts of laws principles thereof)
and for all purposes shall be governed by, and construed in accordance with, the
laws of said State.
