<PAGE>

basis of a 360-day year of twelve 30-day months. The amount of interest payable

computed shall be computed on the basis of the number of days elapsed in a
360-day year of twelve 30-day months. 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 shall 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 (and
without any reduction of interest or any other payment in respect of any such
acceleration), in each case with the same force and effect as if made on the
date such payment was originally payable.

      (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 Company shall pay as additional payments ("Additional
Payments") 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 shall be equal to the amounts the Trust and the
Property Trustee would have received had no such taxes, duties, assessments or
other government charges been imposed.

      SECTION 2.6. EXECUTION AND AUTHENTICATION.

      (a) The Debentures shall be signed on behalf of the Company by its Chief
Executive Officer, President or one of its Senior Vice Presidents, under its

been duly authenticated and delivered hereunder and that the holder is entitled
to the benefits of this Indenture.

      (c) At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debentures executed by the Company to
the Trustee for authentication, together with a written order of the Company for

responsibilities under this Indenture in relation to such Debentures, the
Trustee shall be entitled to receive, and (subject to Section 9.1) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been established in conformity with the provisions of this
Indenture.

the issue of such Debentures pursuant to this Indenture shall affect the
Trustee's own rights, duties or immunities under the Debentures and this
Indenture or otherwise in a manner that is not reasonably acceptable to the
Trustee.

      (b) The Company shall keep, or cause to be kept, at its office or agency
designated for such purpose in the Borough of Manhattan, the City of New York,
or at the office of the Debenture Registrar, or such other location designated
by the Company a register or registers (herein referred to as the "Debenture
Register") in which, subject to such reasonable regulations


                                       12
<PAGE>
as the Debenture Registrar (as defined below) may prescribe, the Company shall
register the Debentures and the transfers of Debentures as provided in this
Article II and which at all reasonable times shall be open for inspection by the
Trustee. The registrar for the purpose of registering Debentures and transfer of
Debentures as herein provided shall initially be the Trustee and thereafter as
may be appointed by the Company as authorized by Board Resolution (the
"Debenture Registrar"). Upon surrender for transfer of any Debenture at the
office or agency of the Company designated for such purpose, the Company shall
execute, the Trustee shall authenticate and such office or agency shall deliver
in the name of the transferee or transferees a new Debenture or Debentures for a
like aggregate principal amount. All Debentures presented or surrendered for
exchange or registration of transfer, as provided in this Section 2.7, shall be
accompanied (if so required by the Company or the Debenture Registrar) by a
written instrument or instruments of transfer, in form satisfactory to the
Company or the Debenture Registrar, duly executed by the registered holder or by
such holder's duly authorized attorney in writing.

      (c) No service charge shall be made for any exchange or registration of
transfer of Debentures, or issue of new Debentures in case of partial
redemption, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge in relation thereto, other than exchanges
pursuant to Section 2.8, Section 3.5(b) and Section 11.4 not involving any
transfer.

      (d) The Company shall not be required (i) to issue, exchange or register
the transfer of any Debentures during a period beginning at the opening of
business fifteen (15) days before the day of the mailing of a notice of
redemption of less than all the Outstanding Debentures and ending at the close
of business on the day of such mailing; nor (ii) to register the transfer of or
exchange any Debentures or portions thereof called for redemption.

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

      SECTION 2.8. TEMPORARY DEBENTURES. Pending the preparation of definitive
Debentures, the Company may execute, and the Trustee shall authenticate and
deliver, temporary Debentures (printed, lithographed, or typewritten). Such
temporary Debentures shall be substantially in the form of the definitive
Debentures in lieu of which they are issued, but with such omissions, insertions
and variations as may be appropriate for temporary Debentures, all as may be
determined by the Company. Every temporary Debenture shall be executed by the
Company and be authenticated by the Trustee upon the same conditions and in
substantially the same manner, and with like effect, as the definitive
Debentures. Without unnecessary delay, the Company shall execute and shall
furnish definitive Debentures and thereupon any or all temporary Debentures may
be surrendered in exchange therefor (without charge to the holders), at the
office or agency of the Company designated for the purpose and the Trustee shall
authenticate and such office or agency shall deliver in exchange for such
temporary Debentures an equal aggregate principal amount of definitive
Debentures, unless the Company advises the Trustee to the effect that definitive
Debentures need not be authenticated and furnished until further notice from the
Company. Until so exchanged, the temporary Debentures shall be


                                       13
<PAGE>
entitled to the same benefits under this Indenture as definitive Debentures
authenticated and delivered hereunder.

      SECTION 2.9. MUTILATED, DESTROYED, LOST OR STOLEN DEBENTURES.

      (a) In case any temporary or definitive Debenture shall become mutilated
or be destroyed, lost or stolen, the Company (subject to the next succeeding
sentence) shall execute, and upon the Company's request the Trustee (subject as
aforesaid) shall authenticate and deliver, a new Debenture bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated
Debenture, or in lieu of and in substitution for the Debenture so destroyed,
lost, stolen or mutilated. In every case the applicant for a substituted
Debenture shall furnish to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, and, in
every case of destruction, loss or theft, the applicant shall also furnish to
the Company and the Trustee evidence to their satisfaction of the destruction,
loss or theft of the applicant's Debenture and of the ownership thereof. The
Trustee shall authenticate any such substituted Debenture and deliver the same
upon the written request or authorization of the Chief Executive Officer,
President or any Senior Vice President and the Treasurer or any Assistant
Treasurer of the Company. Upon the issuance of any substituted Debenture, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
In case any Debenture that has matured or is about to mature shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Debenture, pay or authorize the payment of the same (without
surrender thereof except in the case of a mutilated Debenture) if the applicant
for such payment shall furnish to the Company and the Trustee such security or
indemnity as they may require to save them harmless, and, in case of
destruction, loss or theft, evidence to the satisfaction of the Company and the
Trustee of the destruction, loss or theft of such Debenture and of the ownership
thereof.

      (b) Every replacement Debenture issued pursuant to the provisions of this
Section 2.9 shall constitute an additional contractual obligation of the Company
whether or not the mutilated, destroyed, lost or stolen Debenture shall be found
at any time, or be enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Debentures duly issued hereunder. All Debentures shall be held and owned upon
the express condition that the foregoing provisions are exclusive with respect
to the replacement or payment of mutilated, destroyed, lost or stolen
Debentures, and shall preclude (to the extent lawful) any and all other rights
or remedies, notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

      SECTION 2.10. CANCELLATION. All Debentures surrendered for the purpose of
payment, redemption, exchange or registration of transfer shall, if surrendered
to the Company or any Paying Agent, be delivered to the Trustee for
cancellation, or, if surrendered to the Trustee, shall be canceled by it, and no
Debentures shall be issued in lieu thereof except as expressly required or
permitted by any of the provisions of this Indenture. On request of the Company
at the time of such surrender, the Trustee shall deliver to the Company canceled
Debentures held by the


                                       14
<PAGE>
Trustee. In the absence of such request the Trustee may dispose of canceled
Debentures in accordance with its standard procedures and deliver a certificate
of disposition to the Company. If the Company shall otherwise acquire any of the
Debentures, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Debentures unless and until
the same are delivered to the Trustee for cancellation.

      SECTION 2.11. BENEFIT OF INDENTURE. Nothing in this Indenture or in the
Debentures, express or implied, shall give or be construed to give to any
Person, other than the parties hereto and the holders of the Debentures (and,
with respect to the provisions of Article XVI, the holders of the Senior
Indebtedness) any legal or equitable right, remedy or claim under or in respect
of this Indenture, or under any covenant, condition or provision herein
contained; all such covenants, conditions and provisions being for the sole
benefit of the parties hereto and of the holders of the Debentures (and, with
respect to the provisions of Article XVI, the holders of the Senior
Indebtedness).

      SECTION 2.12. AUTHENTICATION AGENT.

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

      (b) Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time (and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint a
successor Authenticating Agent eligible under the provisions of Section 12.2(a)
of this Indenture. Any successor Authenticating Agent, upon acceptance of its
appointment hereunder, shall become vested with all the rights, powers and
duties of its predecessor hereunder as if originally named as an Authenticating
Agent pursuant hereto.

                                  ARTICLE III.
                            REDEMPTION OF DEBENTURES

      SECTION 3.1. REDEMPTION. The Company may redeem the Debentures issued
hereunder on and after the dates set forth in and in accordance with the terms
of this Article III.


                                       15
<PAGE>
      SECTION 3.2. SPECIAL EVENT REDEMPTION. If a Special Event has occurred and
is continuing, then, notwithstanding Section 3.3(a) but subject to Section
3.3(b), the Company shall have the right upon not less than thirty (30) days'
nor more than sixty (60) days' notice to the holders of the Debentures to redeem
the Debentures, in whole but not in part, for cash within one hundred eighty
(180) days following the occurrence of such Special Event (the "180-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
Company the opportunity to eliminate, within the 180-Day Period, a Tax Event by
taking some ministerial action (a "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 Company, the Trust or the holders of the Trust
Securities issued by the Trust, the Company shall pursue such Ministerial Action
in lieu of redemption, and, provided further, that the Company shall have no
right to redeem the Debentures pursuant to this Section 3.2 while it is pursuing
any Ministerial Action pursuant to its obligations hereunder, and, provided
further, that, if it is determined that the taking of a Ministerial Action would
not eliminate the Tax Event within the 180-Day Period, the Company's right to
redeem the Debentures pursuant to this Section 3.2 shall be restored and it
shall have no further obligations to pursue the Ministerial Action. The
Redemption Price shall be paid prior to 12:00 noon, New York time, on the date
of such redemption or such earlier time as the Company determines, provided that
the Company shall deposit with the Trustee an amount sufficient to pay the
Redemption Price by 10:00 a.m., New York time, on the date such Redemption Price
is to be paid.

      SECTION 3.3. OPTIONAL REDEMPTION BY THE COMPANY.

      (a) Subject to the provisions of Section 3.3(c), except as otherwise may
be specified in this Indenture, the Company shall have the right to redeem the
Debentures, in whole or in part, from time to time, on or after June 30, 2007,
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. Any
redemption pursuant to this Section 3.3(a) shall be made upon not less than
thirty (30) days' nor more than sixty (60) days' notice to the holder of the
Debentures, at the Redemption Price. If the Debentures are only partially
redeemed pursuant to this Section 3.3(a), the Debentures shall be redeemed pro
rata or by lot or in such other manner as the Trustee shall deem appropriate and
fair in its discretion. The Redemption Price shall be paid prior to 12:00 noon,
New York time, on the date of such redemption or at such earlier time as the
Company determines provided that the Company shall deposit with the Trustee an
amount sufficient to pay the Redemption Price by 10:00 a.m., New York time, on
the date such Redemption Price is to be paid.

      (b) Subject to the provisions of Section 3.3(c), the Company shall have
the right to redeem Debentures at any time and from time to time in a principal
amount equal to the Liquidation Amount (as defined in the Trust Agreement) of
any Preferred Securities purchased and beneficially owned by the Company, plus
an additional principal amount of Debentures equal to the Liquidation Amount (as
defined in the Trust Agreement) of that number of Common Securities that bears
the same proportion to the total number of Common Securities then outstanding as
the number of Preferred Securities to be redeemed bears to the total number of
Preferred Securities then outstanding. Such Debentures shall be redeemed
pursuant to this


                                       16
<PAGE>
Section 3.3(b) only in exchange for and upon surrender by the Company to the
Property Trustee of the Preferred Securities and a proportionate amount of
Common Securities, whereupon the Property Trustee shall cancel the Preferred
Securities and Common Securities so surrendered and a Like Amount (as defined in
the Trust Agreement) of Debentures shall be extinguished by the Trustee and
shall no longer be deemed Outstanding.

      (c) If a partial redemption of the Debentures would result in the
delisting of the Preferred Securities from the New York Stock Exchange or from
any national securities exchange or in the termination of inclusion of the
Preferred Securities issued by the Trust from the Nasdaq National Market or
other trading system on or in which the Preferred Securities are then listed,
quoted or included, the Company shall not be permitted to effect such partial
redemption and may only redeem the Debentures in whole or in part to such extent
as would not cause a delisting.

      SECTION 3.4. NOTICE OF REDEMPTION.

      (a) Except in the case of a redemption pursuant to Section 3.3(b), in case
the Company shall desire to exercise such right to redeem all or, as the case
may be, a portion of the Debentures in accordance with the right reserved so to
do, the Company shall, or shall cause the Trustee to upon receipt of forty-five
(45) days' written notice from the Company (which notice shall, in the event of
a partial redemption, include a representation to the effect that such partial
redemption will not result in the delisting of the Preferred Securities as
described in Section 3.3(c) above), give notice of such redemption to holders of
the Debentures to be redeemed by mailing, first class postage prepaid, a notice
of such redemption not less than thirty (30) days and not more than sixty (60)
days before the date fixed for redemption to such holders at their last
addresses as they shall appear upon the Debenture Register unless a shorter
period is specified in the Debentures to be redeemed. Any notice that is mailed
in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the registered holder receives the notice. In any case,
failure duly to give such notice to the holder of any Debenture designated for
redemption in whole or in part, or any defect in the notice, shall not affect
the validity of the proceedings for the redemption of any other Debentures. In
the case of any redemption of Debentures prior to the expiration of any
restriction on such redemption provided in the terms of such Debentures or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with any such restriction. Each such
notice of redemption shall specify the date fixed for redemption and the
Redemption Price and shall state that payment of the Redemption Price shall be
made at the office or agency of the Company in the Borough of Manhattan, the
City of New York or at the Corporate Trust Office, upon presentation and
surrender of such Debentures, that interest accrued to the date fixed for
redemption shall be paid as specified in said notice and that from and after
said date interest shall cease to accrue. If less than all the Debentures are to
be redeemed, the notice to the holders of the Debentures shall specify the
particular Debentures to be redeemed. If the Debentures are to be redeemed in
part only, the notice shall state the portion of the principal amount thereof to
be redeemed and shall state that on and after the redemption date, upon
surrender of such Debenture, a new Debenture or Debentures in principal amount
equal to the unredeemed portion thereof shall be issued.


                                       17
<PAGE>
      (b) Except in the case of a redemption pursuant to Section 3.3(b), if less
than all the Debentures are to be redeemed, the Company shall give the Trustee
at least forty-five (45) days' written notice in advance of the date fixed for
redemption as to the aggregate principal amount of Debentures to be redeemed,
and thereupon the Trustee shall select, pro rata or by lot or in such other
manner as it shall deem appropriate and fair in its discretion, the portion or
portions (equal to $25 or any integral multiple thereof) of the Debentures to be
redeemed and shall thereafter promptly notify the Company in writing of the
numbers of the Debentures to be redeemed, in whole or in part. The Company may,
if and whenever it shall so elect pursuant to the terms hereof, by delivery of
instructions signed on its behalf by its Chief Executive Officer, President or
any Senior Vice President, instruct the Trustee or any Paying Agent to call all
or any part of the Debentures for redemption and to give notice of redemption in
the manner set forth in this Section 3.4, such notice to be in the name of the
Company or its own name as the Trustee or such Paying Agent may deem advisable.
In any case in which notice of redemption is to be given by the Trustee or any
such Paying Agent, the Company shall deliver or cause to be delivered to, or
permit to remain with, the Trustee or such Paying Agent, as the case may be,
such Debenture Register, transfer books or other records, or suitable copies or
extracts therefrom, sufficient to enable the Trustee or such Paying Agent to
give any notice by mail that may be required under the provisions of this
Section 3.4.

      SECTION 3.5. PAYMENT UPON REDEMPTION.

      (a) If the giving of notice of redemption shall have been completed as
above provided, the Debentures or portions of Debentures to be redeemed
specified in such notice shall become due and payable on the date and at the
place stated in such notice at the applicable Redemption Price, and interest on
such Debentures or portions of Debentures shall cease to accrue on and after the
date fixed for redemption, unless the Company shall default in the payment of
such Redemption Price with respect to any such Debenture or portion thereof. On
presentation and surrender of such Debentures on or after the date fixed for
redemption at the place of payment specified in the notice, said Debentures
shall be paid and redeemed at the Redemption Price (but if the date fixed for
redemption is an Interest Payment Date, the interest installment payable on such
date shall be payable to the registered holder at the close of business on the
applicable record date pursuant to Section 3.3).

      (b) Upon presentation of any Debenture that is to be redeemed in part
only, the Company shall execute and the Trustee shall authenticate and the
office or agency where the Debenture is presented shall deliver to the holder
thereof, at the expense of the Company, a new Debenture of authorized
denomination in principal amount equal to the unredeemed portion of the
Debenture so presented.

      SECTION 3.6. NO SINKING FUND.

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


                                       18

                                   ARTICLE IV.
                      EXTENSION OF INTEREST PAYMENT PERIOD

      SECTION 4.1. EXTENSION OF INTEREST PAYMENT PERIOD. So long as no Event of
Default has occurred and is continuing, the Company 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 twenty (20) consecutive quarters (the "Extension Period"),
during which Extension Period no interest shall be due and payable; provided
that no Extension Period may extend beyond the Maturity Date or end on a date
other than an Interest Payment 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, shall bear interest
thereon at the Coupon Rate compounded quarterly for each quarter of the
Extension Period ("Compounded Interest"). At the end of the Extension Period,
the Company shall calculate (and deliver such calculation to the Trustee) and
pay all interest accrued and unpaid on the Debentures, including any Additional
Payments and Compounded Interest (together, "Deferred Payments") that shall be
payable to the holders of the Debentures in whose names the Debentures are
registered in the Debenture Register on the first record date after the end of
the Extension Period. Before the termination of any Extension Period, the
Company may further extend such period so long as no Event of Default has
occurred and is continuing, provided that such period together with all such
further extensions thereof shall not exceed twenty (20) consecutive quarters, or
extend beyond the Maturity Date of the Debentures or end on a date other than an
Interest Payment Date. Upon the termination of any Extension Period and upon the
payment of all Deferred Payments then due, the Company may commence 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, but the
Company may prepay at any time all or any portion of the interest accrued during
an Extension Period.

      SECTION 4.2. NOTICE OF EXTENSION.

      (a) If the Property Trustee is the only registered holder of the
Debentures at the time the Company selects an Extension Period, the Company
shall give written notice to the Administrative Trustees, the Property Trustee
and the Trustee of its selection of such Extension Period at least two (2)
Business Days before the earlier of (i) the next succeeding date on which
Distributions on the Trust Securities issued by the Trust are payable; or (ii)
the date the Trust is required to give notice of the record date, or the date
such Distributions are payable, to the New York Stock Exchange or other
applicable exchange or the Nasdaq National Market or other comparable trading
system or to holders of the Preferred Securities issued by the Trust, but in any
event at least one Business Day before such record date.

      (b) If the Property Trustee is not the only holder of the Debentures at
the time the Company selects an Extension Period, the Company shall give the
holders of the Debentures and the Trustee written notice of its selection of
such Extension Period at least two (2) Business Days before the earlier of (i)
the next succeeding Interest Payment Date; or (ii) the date the Company is
required to give notice of the record or payment date of such interest payment
to the New York Stock Exchange or other applicable exchange or the Nasdaq
National Market or other comparable trading system or to holders of the
Debentures.


                                       19
<PAGE>
      (c) The quarter in which any notice is given pursuant to paragraphs (a) or
(b) of this Section 4.2 shall be counted as one of the twenty (20) quarters
permitted in the maximum Extension Period permitted under Section 4.1.

      SECTION 4.3. LIMITATION ON TRANSACTIONS. If (a) the Company shall exercise
its right to defer payment of interest as provided in Section 4.1; or (b) there
shall have occurred and be continuing any Event of Default, then (i) neither the
Company nor any of its Subsidiaries shall declare or pay any dividend on, make
any distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (A)
dividends or distributions in common stock of the Company, or any declaration of
a non-cash dividend in connection with the implementation of a shareholder
rights plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto, (B) purchases of
common stock of the Company related to the rights under any of the Company's
benefit plans for its directors, officers or employees, (C) as a result of a
reclassification of its capital stock for another class of its capital stock,
(D) dividends or distributions made by a Subsidiary to the Company, or (E)
dividends or distributions made by a Subsidiary to a Subsidiary); (ii) neither
the Company nor any Subsidiary shall make any payment of interest, principal or
premium, if any, or repay, repurchase or redeem any debt securities issued by
the Company or any Subsidiary which rank pari passu with or junior to the
Debentures or make any guarantee payments with respect to any guarantee by the
Company of any debt securities if such guarantee ranks pari passu with or junior
in interest to the Debentures; provided, however, that notwithstanding the
foregoing the Company may make payments pursuant to its obligations under the
Preferred Securities Guarantee; and (iii) the Company shall not redeem, purchase
or acquire less than all of the Outstanding Debentures or any of the Preferred
Securities.

                                   ARTICLE V.
                       PARTICULAR COVENANTS OF THE COMPANY

      SECTION 5.1. PAYMENT OF PRINCIPAL AND INTEREST. The Company shall duly and
punctually pay or cause to be paid the principal of and interest on the
Debentures at the time and place and in the manner provided herein. Each such
payment of the principal of and interest on the Debentures shall relate only to
the Debentures, shall not be combined with any other payment of the principal of
or interest on any other obligation of the Company, and shall be clearly and
unmistakably identified as pertaining to the Debentures.

      SECTION 5.2. MAINTENANCE OF AGENCY. So long as any of the Debentures
remain Outstanding, the Company shall maintain, or shall cause to be maintained,
an office or agency in the Borough of Manhattan, the City of New York, and at
such other location or locations as may be designated as provided in this
Section 5.2, where (a) Debentures may be presented for payment; (b) Debentures
may be presented as hereinabove authorized for registration of transfer and
exchange; and (c) notices and demands to or upon the Company in respect of the
Debentures and this Indenture may be given or served, such designation to
continue with respect to such office or agency until the Company shall, by
written notice signed by its President or an Senior Vice President and delivered
to the Trustee, designate some other office or agency for such purposes or any
of them. If at any time the Company shall fail to maintain any such required


                                       20
<PAGE>
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, notices and demands may be made or served at the Corporate
Trust Office of the Trustee, and the Company hereby appoints the Trustee as its
agent to receive all such presentations, notices and demands. In addition to any
such office or agency, the Company may from time to time designate one or more
offices or agencies outside of the Borough of Manhattan, the City of New York,
where the Debentures may be presented for registration or transfer and for
exchange in the manner provided herein, and the Company may from time to time
rescind such designation as the Company may deem desirable or expedient;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain any such office or agency in
the Borough of Manhattan, the City of New York, for the purposes above
mentioned. The Company shall give the Trustee prompt written notice of any such
designation or rescission thereof.

      SECTION 5.3. PAYING AGENTS.

      (a) The Company shall be the initial Paying Agent. If the Company shall
appoint one or more Paying Agents for the Debentures, other than the Trustee,
the Company shall cause each such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject
to the provisions of this Section 5.3:

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

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

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

            (iv) that it shall perform all other duties of Paying Agent as set
      forth in this Indenture.

      (b) If the Company shall act as its own Paying Agent with respect to the
Debentures, it shall on or before each due date of the principal of or interest
on such Debentures, set aside, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay such principal or interest
so becoming due on Debentures until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and shall promptly notify the Trustee
of such action, or any failure (by it or any other obligor on such Debentures)
to take such action. Whenever the Company shall have one or more Paying Agents
for the Debentures, it shall, prior to each due date of the principal of or
interest on any Debentures, deposit with the Paying Agent a sum sufficient to
pay the principal or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal or interest, and (unless
such Paying Agent is the Trustee) the Company shall promptly notify the Trustee
of this action or failure so to act.

      (c) Notwithstanding anything in this Section 5.3 to the contrary, (i) the
agreement to hold sums in trust as provided in this Section 5.3 is subject to
the provisions of Section 13.3 and 13.4; and (ii) the Company may at any time,
for the purpose of obtaining the satisfaction and discharge of this Indenture or
for any other purpose, pay, or direct any Paying Agent to pay, to the Trustee
all sums held in trust by the Company or such Paying Agent, such sums to be held
by the Trustee upon the same terms and conditions as those upon which such sums
were held by the Company or such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

      SECTION 5.4. APPOINTMENT TO FILL VACANCY IN OFFICE OF THE TRUSTEE. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
shall appoint, in the manner provided in Section 9.11, a Trustee, so that there
shall at all times be a Trustee hereunder.

      SECTION 5.5. COMPLIANCE WITH CONSOLIDATION PROVISIONS. The Company shall
not, while any of the Debentures remain Outstanding, consolidate with, or merge
into, or merge into itself, or sell or convey all or substantially all of its
property to any other company unless the provisions of Article XII hereof are
complied with.

      SECTION 5.6. LIMITATION ON TRANSACTIONS. If Debentures are issued to the
Trust or a trustee of the Trust in connection with the issuance of Trust
Securities by the Trust and (a) there shall have occurred and be continuing an
Event of Default; (b) the Company shall be in default with respect to its
payment of any obligations under the Preferred Securities Guarantee relating to
the Trust; or (c) if the Company shall have given notice of its election to
defer payments of interest on such Debentures by extending the interest payment
period as provided in this Indenture and such Extension Period, or any extension
thereof, shall be continuing, then (i) neither the Company nor any of its
Subsidiaries shall declare or pay any dividend on, make any distributions with
respect to, or redeem, purchase, acquire or make a liquidation payment with
respect to, any of its capital stock (other than (A) dividends or distributions
in common stock of the Company, or any declaration of a non-cash dividend in
connection with the implementation of a shareholder rights plan, or the issuance
of stock under any such plan in the future, or the redemption or repurchase of
any such rights pursuant thereto, (B) purchases of common stock of the Company
related to the rights under any of the Company's benefit plans for its
directors, officers or employees, (C) as a result of a reclassification of its
capital stock, or (D) dividends or distributions made by a Subsidiary to the
Company, or (E) dividends or distributions made by a Subsidiary to a
Subsidiary); (ii) neither the Company nor any Subsidiary shall make any payment
of principal, interest or premium, if any, or repay, repurchase or redeem any
debt securities issued by the Company or any Subsidiary which rank pari passu
with or junior in interest to the Debentures or make any guarantee payments with
respect to any guarantee by the Company of any debt securities if such guarantee
ranks pari passu with or junior in interest to the Debentures; provided,
however, that the Company may make payments pursuant to its obligations under
the Preferred Securities Guarantee; and (iii) the Company shall not redeem,
purchase or acquire less than all of the Outstanding Debentures or any of the
Preferred Securities.


                                       22
<PAGE>
      SECTION 5.7. COVENANTS AS TO THE TRUST. For so long as the Trust
Securities of the Trust remain outstanding, the Company (a) shall maintain 100%
direct or indirect ownership of the Common Securities of the Trust; provided,
however, that any permitted successor of the Company under this Indenture may
succeed to the Company's ownership of the Common Securities; (b) shall use its
reasonable efforts to cause the Trust (i) to remain a business trust (and to
avoid involuntary termination, winding up or liquidation), except in connection
with a distribution of Debentures, the redemption of all of the Trust Securities
of the Trust or certain mergers, consolidations or amalgamations, each as
permitted by the Trust Agreement; and (ii) to otherwise continue not to be
treated as an association taxable as a corporation or partnership for United
States federal income tax purposes; (c) shall use its reasonable efforts to
cause each holder of Trust Securities to be treated as owning an individual
beneficial interest in the Debentures; and (d) including any successor to the
Company, shall use best efforts to maintain the eligibility of the Preferred
Securities for listing, quotation or inclusion on or in any national securities
exchange or other trading system on or in which the Preferred Securities are
then listed, quoted or included (including, if applicable, the New York Stock
Exchange) and shall use best efforts to keep the Preferred Securities so listed,
quoted or included for so long as the Preferred Securities remain outstanding.
In connection with the distribution of the Debentures to the holders of the
Preferred Securities issued by the Trust upon a Dissolution Event, the Company
shall use its best efforts to list such Debentures on the New York Stock
Exchange or such other exchange or to include such Debentures in such trading
system as the Preferred Securities are then listed, quoted or included. For so
long as the Debenture shall remain Outstanding, the Company shall fulfill all
reporting and filing obligations under the Securities Exchange Act of 1934, as
amended, as applicable to companies having a class of securities registered
under Section 12(b) or 12(g) thereunder.

      SECTION 5.8. COVENANTS AS TO PURCHASES. Except upon the exercise by the
Company of its right to redeem the Debentures pursuant to Section 3.2 upon the
occurrence and continuation of a Special Event, the Company shall not purchase
any Debentures, in whole or in part, from the Trust prior to June 30, 2007.

      SECTION 5.9. WAIVER OF USURY, STAY OR EXTENSION LAWS. The Company shall
not at any time insist upon, or plead, or in any manner whatsoever claim or take
the benefit or advantage of, any usury, stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performances of this Indenture, and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the extension of
every such power as though no such law had been enacted.

      SECTION 5.10. LIMITATION ON ADDITIONAL JUNIOR INDEBTEDNESS. The Company
shall not, and it shall not cause or permit any Subsidiary of the Company to,
incur, issue or be obligated on any Additional Junior Indebtedness, either
directly or indirectly, by way of guarantee, suretyship or otherwise, other
than:

      (a) Additional Junior Indebtedness that, by its terms, is expressly stated
to be junior and subordinate in all respects to the Debentures; or


                                       23
<PAGE>
      (b) Additional Junior Indebtedness that, by its terms, is expressly stated
to be pari passu and rank equally in all respects with the Debentures; provided,
however, that neither the Company nor any of its Subsidiaries shall incur, issue
or otherwise become obligated on any Additional Junior Indebtedness pursuant to
this Section 5.10(b) unless the quotient of "X" divided by "Y" is less than 0.60
upon incurring, issuing or otherwise becoming obligated on any Additional Junior
Indebtedness, where "X" and "Y" are calculated as described in Section 5.10(c)
and 5.10(d), respectively.

      (c) As used in Section 5.10(b), "X" means the sum of the following:

            (i) the aggregate liquidation amount or principal amount, as the
      case may be, of the Debentures Outstanding at the time of the proposed
      issuance of such Additional Junior Indebtedness pursuant to Section
      5.10(b), plus

            (ii) the aggregate liquidation amount or principal amount, as the
      case may be, of any Additional Junior Indebtedness previously issued and
      outstanding at the time of the proposed issuance of such Additional Junior
      Indebtedness pursuant to Section 5.10(b), excluding any such Additional
      Junior Indebtedness that, by its terms, is expressly stated to be junior
      and subordinate in all respects to the Debentures, plus

            (iii) the aggregate liquidation amount or principal amount, as the
      case may be, of the Additional Junior Indebtedness proposed to be issued
      or otherwise incurred pursuant to Section 5.10(b), plus

            (iv) the principal amount of any Senior Indebtedness, other than
      Additional Junior Indebtedness, of the Company outstanding at the time of
      the proposed issuance of such Additional Junior Indebtedness pursuant to
      Section 5.10(b) and that has a maturity or is otherwise due and payable by
      the Company on a date twelve (12) months or more after the time of the
      proposed issuance of such Additional Junior Indebtedness pursuant to
      Section 5.10(b);

            less, any indebtedness described in clauses (i) to (iv) above to be
      paid with the proceeds of the Additional Junior Indebtedness then proposed
      to be incurred, issued or upon which the Company is then to become
      obligated.

      (d) As used in Section 5.10(b), "Y" means the sum of the following:

            (i) the stockholders' equity of the Company (calculated on a
      consolidated basis and in accordance with Generally Accepted Accounting
      Principles) determined as of the last day of the month immediately
      preceding the month during which the proposed issuance of the Additional
      Junior Indebtedness pursuant to Section 5.10(b) is scheduled to occur,
      (provided, however, that in no event shall any portion of the Debentures,
      the Additional Junior Indebtedness or the Senior Indebtedness described in
      Section 5.10(c) also be included in "Y" under this Section 5.10(d)), plus


                                       24
<PAGE>
            (ii) the aggregate liquidation amount or principal amount, as the
      case may be, of any Additional Junior Indebtedness, which by its terms is
      expressly stated to be junior and subordinate in all respects to the
      Debentures and which was previously issued and outstanding at the time of
      the proposed issuance of such Additional Junior Indebtedness pursuant to
      Section 5.10(b).

      (e) Notwithstanding the foregoing, the limitations of this Section 5.10
shall not in any way preclude the Company from merging with or into, or from
acquiring or being acquired by, another Person (including by way of merger,
stock purchase or acquisition of assets) that is not a Subsidiary of the Company
in an arm's length transaction entered into in good faith, even though the pro
forma consolidated balance sheet of the surviving Person immediately following
the consummation of such merger, or of the acquiror immediately following the
completion of such acquisition transaction, may include Additional Junior
Indebtedness in amounts in excess of amounts that would otherwise be permitted
by this Section 5.10; provided, however, that thereafter the limitations on
future incurrences of Additional Junior Indebtedness in this Section 5.10 shall
continue to apply to the Company (in the event that it is the surviving
corporation in such merger transaction or the acquiror in such acquisition
transaction) and shall apply to the other Person (in the event that it is the
surviving corporation in such merger transaction or the acquiror in such
acquisition transaction) whether or not such other Person is expressly made a
party hereto.

      SECTION 5.11 FALL AWAY EVENT. In the event that the Preferred Securities
or the Debentures are rated Investment Grade Status by any of Moody's or S&P,
the Company shall deliver an Officers' Certificate to the Trustee to that
effect, and thereafter Section 5.10 of this Indenture shall be null and void and
shall no longer be applicable in any respect to the Company or its Subsidiaries.

      SECTION 5.12 NO INTENT TO COMMENCE AN EXTENSION PERIOD. The Company has no
present intention to exercise its right under Section 4.1 to defer payments of
interest on the Debentures by selecting an Extension Period. The Company
believes that the likelihood that it would exercise its right under Section 4.1
to defer payments of interest on the Debentures by selecting an Extension Period
at any time during which the Debentures are outstanding is remote because of the
restrictions that would be imposed on the Company pursuant to Sections 4.3 and
5.6 of this Indenture.

                                   ARTICLE VI.
                     THE DEBENTUREHOLDERS' LISTS AND REPORTS

DEBENTUREHOLDERS.

Company may be required to file with the Commission pursuant to Section 13 or
Section 15(d) of the Exchange Act; or, if the Company is not required to file

      (b) The Company covenants and agrees to file with the Trustee and the

<PAGE>
thirty (30) days after the filing thereof with the Trustee, such summaries of
any information, documents and reports required to be filed by the Company
pursuant to subsections (a) and (b) of this Section 6.3 as may be required by
rules and regulations prescribed from time to time by the Commission.

      SECTION 6.4. REPORTS BY THE TRUSTEE.

      (a) On or before October 15 in each year in which any of the Debentures
are Outstanding, the Trustee shall transmit by mail, first class postage
prepaid, to the Debentureholders, as their names and addresses appear upon the
Debenture Register, a brief report dated as of the preceding September 30, if
and to the extent required under Section 313(a) of the Trust Indenture Act.

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

      (c) A copy of each such report shall, at the time of such transmission to
Debentureholders, be filed by the Trustee with the Company, with the New York
Stock Exchange, or other stock exchange on which any Debentures are listed
and/or the Nasdaq National Market or any other trading system on or in which any
Debentures are quoted or included (if so listed, quoted or included) and also
with the Commission. The Company agrees to notify the Trustee when any
Debentures become listed on the New York Stock Exchange or on any other stock
exchange or designated for inclusion or quotation in or on the Nasdaq National
Market or any other trading system.

                                  ARTICLE VII.
                  REMEDIES OF THE TRUSTEE AND DEBENTUREHOLDERS
                               ON EVENT OF DEFAULT

      SECTION 7.1. EVENTS OF DEFAULT.

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

            (i) the Company defaults in the payment of any installment of
      interest upon any of the Debentures, as and when the same shall become due
      and payable, and continuance of such default for a period of thirty (30)
      days; provided, however, that a valid extension of an interest payment
      period by the Company in accordance with the terms of this Indenture shall
      not constitute a default in the payment of interest for this purpose;

            (ii) the Company defaults in the payment of the principal on the
      Debentures as and when the same shall become due and payable whether at
      maturity, upon redemption, by declaration or otherwise;

            (iii) the Company fails to observe or perform any other of its
      covenants or agreements with respect to the Debentures for a period of
      ninety (90) days after the date


                                       27
<PAGE>
      on which written notice of such failure, requiring the same to be remedied
      and stating that such notice is a "Notice of Default" hereunder, shall
      have been given to the Company by the Trustee, by registered or certified
      mail, or to the Company and the Trustee by the holders of at least
      twenty-five percent (25%) in principal amount of the Debentures at the
      time Outstanding;

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

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

            (vi) the Trust shall have voluntarily or involuntarily dissolved,
      wound-up its business or otherwise terminated its existence except in
      connection with (A) the distribution of Debentures to holders of Trust
      Securities in liquidation of their interests in the Trust; (B) the
      redemption of all of the outstanding Trust Securities of the Trust; or (C)
      certain mergers, consolidations or amalgamations, each as permitted by the
      Trust Agreement.

      (b) In each and every such case referred to in items (i) through (vi) of
Section 7.1(a), unless the principal of all the Debentures shall have already
become due and payable, either the Trustee or the holders of not less than
twenty-five percent (25%) in aggregate principal amount of the Debentures then
Outstanding hereunder, by notice in writing to the Company (and to the Trustee
if given by such Debentureholders) may declare the principal of all the
Debentures to be due and payable immediately, and upon any such declaration the
same shall become and shall be immediately due and payable, notwithstanding
anything contained in this Indenture or in the Debentures.

      (c) At any time after the principal of the Debentures shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, the
holders of at least a majority in aggregate principal amount of the Debentures
then Outstanding hereunder, by written notice to the Company and the Trustee,
may rescind and annul such declaration and its consequences if: (i) the Company
has paid or deposited with the Trustee a sum sufficient to pay all matured
installments of interest upon all the Debentures and the principal of any and
all Debentures that shall have become due otherwise than by acceleration (with
interest upon such principal, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate per annum expressed in the Debentures to the date of such payment or
deposit) and the amount payable to the Trustee under Section 9.7; and (ii) any
and all Events of Default under this Indenture, other than the nonpayment of
principal on Debentures that shall not have become due by their terms, shall
have been remedied or waived as provided in Section 7.6.


                                       28
<PAGE>
No such rescission and annulment shall extend to or shall affect any subsequent
default or impair any right consequent thereon.

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

      SECTION 7.2. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY THE
TRUSTEE.

      (a) The Company covenants that (i) in case it shall default in the payment
of any installment of interest on any of the Debentures, and such default shall
have continued for a period of thirty (30) days (other than by reason of a valid
extension of an interest payment period by the Company in accordance with the
terms of this Indenture); or (ii) in case it shall default in the payment of the
principal of any of the Debentures when the same shall have become due and
payable, whether upon maturity of the Debentures or upon redemption or upon
declaration or otherwise, then, upon demand of the Trustee, the Company shall
pay to the Trustee, for the benefit of the holders of the Debentures, the whole
amount that then shall have become due and payable on all such Debentures for
principal or interest, or both, as the case may be, with interest upon the
overdue principal; and (to the extent that payment of such interest is
enforceable under applicable law and, if the Debentures are held by the Trust or
a trustee of the Trust, without duplication of any other amounts paid by the
Trust or trustee in respect thereof) upon overdue installments of interest at
the rate per annum expressed in the Debentures; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, and the amount payable to the Trustee under Section 9.7.

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

      (c) In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affecting the Company, the Trust, or the creditors or property of either, the
Trustee shall have power to intervene in such proceedings and take any action
therein that may be permitted by the court and shall (except as may be otherwise
provided by law) be entitled to file such proofs of claim and other papers and
documents as may be necessary or advisable in order to have the claims of the
Trustee and of the holders of the Debentures allowed for the entire amount due
and payable by the Company under this Indenture at the date of institution of
such proceedings and for any additional amount that may become due and payable
by the Company after such date, and to collect and receive any


                                       29
<PAGE>
moneys or other property payable or deliverable on any such claim, and to
distribute the same after the deduction of the amount payable to the Trustee
under Section 9.7; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the holders of the Debentures to
make such payments to the Trustee, and, in the event that the Trustee shall
consent to the making of such payments directly to such Debentureholders, to pay
to the Trustee any amount due it under Section 9.7.

      (d) All rights of action and of asserting claims under this Indenture, or
under any of the terms established with respect to the Debentures, may be
enforced by the Trustee without the possession of any of such Debentures, or the
production thereof at any trial or other proceeding relative thereto, and any
such suit or proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for payment to the Trustee of any amounts due under Section 9.7, be
for the ratable benefit of the holders of the Debentures. In case of an Event of
Default hereunder which is continuing, the Trustee may in its discretion proceed
to protect and enforce the rights vested in it by this Indenture by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any of such rights, either at law or in equity or in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law. Nothing contained herein
shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any Debentureholder any plan of reorganization, arrangement,
adjustment or composition affecting the Debentures or the rights of any holder
thereof or to authorize the Trustee to vote in respect of the claim of any
Debentureholder in any such proceeding.

      SECTION 7.3. APPLICATION OF MONEYS COLLECTED. Any moneys or other assets
collected by the Trustee pursuant to this Article VII with respect to the
Debentures shall be applied in the following order, at the date or dates fixed
by the Trustee and, in case of the distribution of such moneys or other assets
on account of principal or interest, upon presentation of the Debentures, and
notation thereon of the payment, if only partially paid, and upon surrender
thereof if fully paid:

            FIRST: To the payment of costs and expenses of collection and of all
      amounts payable to the Trustee under Section 9.7;

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

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

      SECTION 7.4. LIMITATION ON SUITS.

      (a) Except as set forth in this Indenture, no holder of any Debenture
shall have any right by virtue or by availing of any provision of this Indenture
to institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless (i) such holder previously shall have
given to the Trustee written notice of an Event of Default and of the
continuance thereof with respect to the Debentures specifying such Event of
Default, as hereinbefore provided; (ii) the holders of not less than twenty-five
percent (25%) in aggregate principal amount of the Debentures then Outstanding
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as trustee hereunder; (iii) such holder or holders
shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby;
and (iv) the Trustee for sixty (60) days after its receipt of such notice,
request and offer of indemnity shall have failed to institute any such action,
suit or proceeding and during such sixty (60) day period, the holders of at
least a majority in principal amount of the Debentures do not give the Trustee a
direction inconsistent with the request.

      (b) Notwithstanding anything contained herein to the contrary or any other
provisions of this Indenture, the right of any holder of the Debentures to
receive payment of the principal of and interest on the Debentures, as therein
provided, on or after the respective due dates expressed in such Debenture (or
in the case of redemption, on the redemption date), or to institute suit for the
enforcement of any such payment on or after such respective dates or redemption
date, shall not be impaired or affected without the consent of such holder and
by accepting a Debenture hereunder it is expressly understood, intended and
covenanted by the taker and holder of every Debenture with every other such
taker and holder and the Trustee that no one or more holders of the Debentures
shall have any right in any manner whatsoever by virtue or by availing of any
provision of this Indenture to affect, disturb or prejudice the rights of the
holders of any other of such Debentures, or to obtain or seek to obtain priority
over or preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all holders of the Debentures. For the protection and
enforcement of the provisions of this Section 7.4, each and every
Debentureholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.

      SECTION 7.5. RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER.

      (a) Except as otherwise provided in Section 2.9(b), all powers and
remedies given by this Article VII to the Trustee or to the Debentureholders
shall, to the extent permitted by law, be deemed cumulative and not exclusive of
any other powers and remedies available to the Trustee or the holders of the
Debentures, by judicial proceedings or otherwise, to enforce the performance or
observance of the covenants and agreements contained in this Indenture or
otherwise established with respect to such Debentures.

      (b) No delay or omission of the Trustee or of any holder of any of the
Debentures to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such


                                       31
<PAGE>
default or an acquiescence therein; and, subject to the provisions of Section
7.4, every power and remedy given by this Article VII or by law to the Trustee
or the Debentureholders may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Debentureholders.

SECTION 7.6. CONTROL BY THE DEBENTUREHOLDERS. The holders of at least a majority
in aggregate principal amount of the Debentures at the time Outstanding,
determined in accordance with Section 10.4, shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred on the Trustee;
provided, however, that such direction shall not be in conflict with any rule of
law or with this Indenture. Subject to the provisions of Section 9.1, the
Trustee shall have the right to decline to follow any such direction if the
Trustee in good faith 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 or Officers of
the Trustee, determine that the proceeding so directed would involve the Trustee
in personal liability. The holders of at least a majority in aggregate principal
amount of the Debentures at the time Outstanding affected thereby, or the
holders of at least a majority in liquidation preference of the Trust Securities
of the Trust at the time Outstanding affected thereby, in each case determined
in accordance with Section 10.4, may on behalf of the holders of all of the
Debentures or of all of the Preferred Securities waive any past default in the
performance of any of the covenants contained herein and its consequences or any
past Default or Event of Default, except (i) a default in the payment of the
principal of or interest on any of the Debentures as and when the same shall
become due by the terms of such Debentures otherwise than by acceleration
(unless such default has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Trustee (in accordance with Section 7.1(c)); (ii) a
default in the covenants contained in Section 5.7; or (iii) in respect of a
covenant or provision hereof which cannot be modified or amended without the
consent of the holder of each Outstanding Debenture affected; provided, however,
that if the Debentures are held by the Trust or a trustee of the Trust, such
waiver or modification to such waiver shall not be effective until the holders
of a majority in liquidation preference of Trust Securities of the Trust shall
have consented to such waiver or modification to such waiver; provided further,
that if the consent of the holder of each Outstanding Debenture 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 Debentures shall be restored
to their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other default or impair any right consequent
thereon.

      SECTION 7.7. UNDERTAKING TO PAY COSTS. All parties to this Indenture
agree, and each holder of any Debentures by such holder's acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Trustee for any action taken or omitted by it as the
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


                                       32
<PAGE>
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 7.7 shall not apply to any suit instituted by
the Trustee, to any suit instituted by any Debentureholder, or group of the
Debentureholders holding more than ten percent (10%) in aggregate principal
amount of the Outstanding Debentures, or to any suit instituted by any
Debentureholder for the enforcement of the payment of the principal of or
interest on the Debentures, on or after the respective due dates expressed in
such Debenture or established pursuant to this Indenture.

      SECTION 7.8. DIRECT ACTION; RIGHT OF SET-OFF. In the event that an Event
of Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest on or principal of the Debentures on an
Interest Payment Date or Maturity Date, as applicable, then a holder of
Preferred Securities may institute and prosecute a legal proceeding directly
against the Company for enforcement of payment to such holder of the principal
of or interest on such Debentures having a principal amount equal to the
aggregate Liquidation Amount of the Preferred Securities of such holders (a
"Direct Action"). In connection with such Direct Action, the Company will have a
right of set-off under this Indenture to the extent of any payment actually made
by the Company to such holder of the Preferred Securities with respect to such
Direct Action.

                                  ARTICLE VIII.
                    FORM OF THE DEBENTURE AND ORIGINAL ISSUE

      SECTION 8.1. FORM OF DEBENTURE. The Debenture and the Trustee's
Certificate of Authentication to be endorsed thereon are to be substantially in
the forms contained as Exhibit A to this Indenture, attached hereto and
incorporated herein by reference.

      SECTION 8.2. ORIGINAL ISSUE OF THE DEBENTURES. Debentures in the aggregate
principal amount of $30,927,100 may, upon execution of this Indenture, be
executed by the Company and delivered to the Trustee for authentication. If the
Underwriters exercise their Option and there is an Option Closing Date (as such
terms are defined in the Underwriting Agreement, dated April 17, 2002, by and
among the Company, the Trust, and Legg Mason Wood Walker, Incorporated and
Stifel, Nicolaus & Company, Incorporated, as Representatives of the several
Underwriters named therein, then, on such Option Closing Date, Debentures in the
additional aggregate amount of up to $4,639,200 may be executed by the Company
and delivered to the Trustee for authentication. The Trustee shall thereupon
authenticate and deliver said Debentures to or upon the written order of the
Company, signed by its Chief Executive Officer, its President, or any Senior
Vice President and its Treasurer or an Assistant Treasurer, without any further
action by the Company.

                                   ARTICLE IX.
                             CONCERNING THE TRUSTEE

      SECTION 9.1. CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

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

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

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

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

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

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

            (iii) the Trustee shall not be liable with respect to any action
      taken or omitted to be taken by it in good faith in accordance with the
      direction of the holders of not less than a majority in principal amount
      of the Debentures at the time Outstanding relating to the time, method and
      place of conducting any proceeding for any remedy available to the
      Trustee, or exercising any trust or power conferred upon the Trustee under
      this Indenture with respect to the Debentures; and


                                       34
<PAGE>
            (iv) none of the provisions contained in this Indenture shall
      require the Trustee to expend or risk its own funds or otherwise incur
      personal financial liability in the performance of any of its duties or in
      the exercise of any of its rights or powers, if there is reasonable ground
      for believing that the repayment of such funds or liability is not
      reasonably assured to it under the terms of this Indenture or adequate
      indemnity against such risk is not reasonably assured to it.

      SECTION 9.2. NOTICE OF DEFAULTS. Within ninety (90) days after actual
knowledge by a Responsible Officer of the Trustee of the occurrence of any
Default hereunder with respect to the Debentures, the Trustee shall transmit by
mail to all holders of the Debentures, as their names and addresses appear in
the Debenture Register, notice of such Default, unless such Default shall have
been cured or waived; provided, however, that, except in the case of a default
in the payment of the principal or interest (including any Additional Payments)
on any Debenture, the Trustee shall be protected in withholding such notice if
and so long as the board of directors, the executive committee or a trust
committee of the directors and/or Responsible Officers of the Trustee determines
in good faith that the withholding of such notice is in the interests of the
holders of such Debentures; and provided, further, that in the case of any
Default of the character specified in section 7.1(a)(iii), no such notice to
holders of Debentures need be sent until at least thirty (30) days after the
occurrence thereof.

      SECTION 9.3. CERTAIN RIGHTS OF THE TRUSTEE. Except as otherwise provided
in Section 9.1:

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

      (b) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a Board Resolution or an instrument
signed in the name of the Company by its President or any Senior Vice President
and by the Secretary or an Assistant Secretary or the Treasurer or an Assistant
Treasurer thereof (unless other evidence in respect thereof is specifically
prescribed herein);

      (c) The Trustee shall not be deemed to have knowledge of a Default or an
Event of Default, other than an Event of Default specified in Section 7.1(a)(i)
or (ii), unless and until it receives written notification of such Event of
Default from the Company or by holders of at least twenty-five percent (25%) of
the aggregate principal amount of the Debentures at the time Outstanding;

      (d) The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted hereunder in
good faith and in reliance thereon;

      (e) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the Debentureholders, pursuant to the provisions of this Indenture,
unless such Debentureholders shall have offered to


                                       35
<PAGE>
the Trustee reasonable security or indemnity against the costs, expenses and
liabilities that may be incurred therein or thereby; nothing contained herein
shall, however, relieve the Trustee of the obligation, upon the occurrence of an
Event of Default (that is continuing and has not been cured or waived) to
exercise with respect to the Debentures such of the rights and powers vested in
it by this Indenture, and to use the same degree of care and skill in its
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs;

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

      (g) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the Outstanding Debentures
(determined as provided in Section 10.4); provided, however, that if the payment
within a reasonable time to the Trustee of the costs, expenses or liabilities
likely to be incurred by it in the making of such investigation is, in the
opinion of the Trustee, not reasonably assured to the Trustee by the security
afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such costs, expenses or liabilities as a condition
to so proceeding, and the reasonable expense of every such examination shall be
paid by the Company or, if paid by the Trustee, shall be repaid by the Company
upon demand; and

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

      SECTION 9.4. THE TRUSTEE NOT RESPONSIBLE FOR RECITALS, ETC.

      (a) The Recitals contained herein and in the Debentures shall be taken as
the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.

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

      (c) The Trustee shall not be accountable for the use or application by the
Company of any of the Debentures or of the proceeds of such Debentures, or for
the use or application of any moneys paid over by the Trustee in accordance with
any provision of this Indenture, or for the use or application of any moneys
received by any Paying Agent other than the Trustee.

      SECTION 9.5. MAY HOLD THE DEBENTURES. The Trustee or any Paying Agent or
Debenture Registrar for the Debentures, in its individual or any other capacity,
may become the owner or pledgee of the Debentures with the same rights it would
have if it were not Trustee, Paying Agent or Debenture Registrar.


                                       36
<PAGE>
      SECTION 9.6. MONEYS HELD IN TRUST. Subject to the provisions of Section
13.5, all moneys received by the Trustee shall, until used or applied as herein
provided, be held in trust for the purposes for which they were received, but
need not be segregated from other funds except to the extent required by law.
The Trustee shall be under no liability for interest on any moneys received by
it hereunder except such as it may agree with the Company to pay thereon.

      SECTION 9.7. COMPENSATION AND REIMBURSEMENT.

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

      (b) The obligations of the Company under this Section 9.7 to compensate
and indemnify the Trustee and to pay or reimburse the Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder.
Such additional indebtedness shall be secured by a lien prior to that of the
Debentures upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular
Debentures.

      SECTION 9.8. RELIANCE ON OFFICERS' CERTIFICATE. Except as otherwise
provided in Section 9.1, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or suffering or omitting to take any
action hereunder, such matter (unless other evidence in respect thereof is
herein specifically prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee, be deemed to be conclusively proved and established
by an Officers' Certificate delivered to the Trustee and such certificate, in
the absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted to be taken by
it under the provisions of this Indenture upon the faith thereof.

      SECTION 9.9. DISQUALIFICATION; CONFLICTING INTERESTS. If the Trustee has
or shall acquire any "conflicting interest" within the meaning of Section 310(b)
of the Trust Indenture Act, the Trustee and the Company shall in all respects
comply with the provisions of Section 310(b) of the Trust Indenture Act.


                                       37
<PAGE>
      SECTION 9.10. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY. There shall at all
times be a Trustee with respect to the Debentures issued hereunder which shall
at all times be a corporation organized and doing business under the laws of the
United States or any state or territory thereof or of the District of Columbia,
or a corporation or other Person permitted to act as trustee by the Commission,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $50,000,000, and subject to supervision or
examination by federal, state, territorial, or District of Columbia authority.
If such Person 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 9.10, 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. The Company may not, nor may
any Person directly or indirectly controlling, controlled by, or under common
control with the Company, serve as Trustee. In case at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
9.10, the Trustee shall resign immediately in the manner and with the effect
specified in Section 9.11.

      SECTION 9.11. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

      (a) The Trustee or any successor hereafter appointed, may at any time
resign by giving written notice thereof to the Company and by transmitting
notice of resignation by mail, first class postage prepaid, to the
Debentureholders, as their names and addresses appear upon the Debenture
Register. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee with respect to Debentures by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment within thirty (30) days after the mailing of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee with respect to
Debentures, or any Debentureholder who has been a bona fide holder of a
Debenture or Debentures for at least six (6) months may, subject to the
provisions of Sections 9.9 and 9.10, on behalf of himself or herself and all
others similarly situated, petition any such court for the appointment of a
successor trustee. Such court may thereupon after such notice, if any, as it may
deem proper and prescribe, appoint a successor trustee.

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

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

            (ii) the Trustee shall cease to be eligible in accordance with the
      provisions of Section 9.10 and shall fail to resign after written request
      therefor by the Company or by any such Debentureholder; or

            (iii) the Trustee shall become incapable of acting, or shall be
      adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy
      proceeding, or a receiver of the Trustee or of its property shall be
      appointed or consented to, or any public officer


                                       38
<PAGE>
      shall take charge or control of the Trustee or of its property or affairs
      for the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee with respect to all
Debentures and appoint a successor trustee by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee,
or, subject to the provisions of Sections 9.9 and 9.10, unless the Trustee's
duty to resign is stayed as provided herein, any Debentureholder who has been a
bona fide holder of a Debenture or Debentures for at least six months may, on
behalf of that holder and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee. Such court may thereupon after such notice, if any, as it may
deem proper and prescribe, remove the Trustee and appoint a successor trustee.

      (c) The holders of at least a majority in aggregate principal amount of
the Debentures at the time Outstanding may at any time remove the Trustee by so
notifying the Trustee and the Company and may appoint a successor Trustee with
the consent of the Company.

      (d) Any resignation or removal of the Trustee and appointment of a
successor trustee with respect to the Debentures pursuant to any of the
provisions of this Section 9.11 shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 9.12.

      (e) Any successor trustee appointed pursuant to this Section 9.11 may be
appointed with respect to the Debentures, and at any time there shall be only
one Trustee with respect to the Debentures.

      SECTION 9.12. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

      (b) Upon request of any successor trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor trustee all such rights, powers and trusts referred to in
paragraph (a) of this Section 9.12.

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


                                       39
<PAGE>
      (d) Upon acceptance of appointment by a successor trustee as provided in
this Section 9.12, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage prepaid, to the Debentureholders,
as their names and addresses appear upon the Debenture Register. If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company.

      SECTION 9.13. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.
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
the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided that such Person shall be qualified under the
provisions of Section 9.9 and eligible under the provisions of Section 9.10,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding. In
case any Debentures shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Debentures so authenticated with the same effect as if such successor Trustee
had itself authenticated such Debentures.

      SECTION 9.14. PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY. The
Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding
any creditor relationship described in Section 311(b) of the Trust Indenture
Act. A Trustee who has resigned or been removed shall be subject to Section
311(a) of the Trust Indenture Act to the extent included therein.

                                   ARTICLE X.
                         CONCERNING THE DEBENTUREHOLDERS

      SECTION 10.1. EVIDENCE OF ACTION BY THE HOLDERS.

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

      (b) If the Company shall solicit from the Debentureholders any request,
demand, authorization, direction, notice, consent, waiver or other action, the
Company may, at its option, as evidenced by an Officers' Certificate, fix in
advance a record date for the determination of Debentureholders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other
action, but the Company shall have no obligation to do so. If such a record date
is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other action may be given before or after the record date, but only
the Debentureholders of record at the close of business on the record date shall
be deemed to be Debentureholders for the purposes of


                                       40
<PAGE>
determining whether Debentureholders of the requisite proportion of Outstanding
Debentures have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other action, and for that
purpose the Outstanding Debentures shall be computed as of the record date;
provided, however, that no such authorization, agreement or consent by such
Debentureholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
(6) months after the record date.

      SECTION 10.2. PROOF OF EXECUTION BY THE DEBENTUREHOLDERS. Subject to the
provisions of Section 9.1, proof of the execution of any instrument by a
Debentureholder (such proof shall not require notarization) or such
Debentureholder's agent or proxy and proof of the holding by any Person of any
of the Debentures shall be sufficient if made in the following manner:

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

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

      (c) The Trustee may require such additional proof of any matter referred
to in this Section 10.2 as it shall deem necessary.

      SECTION 10.3. WHO MAY BE DEEMED OWNERS. Prior to the due presentment for
registration of transfer of any Debenture, the Company, the Trustee, any Paying
Agent, any Authenticating Agent and any Debenture Registrar may deem and treat
the Person in whose name such Debenture shall be registered upon the books of
the Company as the absolute owner of such Debenture (whether or not such
Debenture shall be overdue and notwithstanding any notice of ownership or
writing thereon made by anyone other than the Debenture Registrar) for the
purpose of receiving payment of or on account of the principal of and interest
on such Debenture (subject to Section 2.3) and for all other purposes; and
neither the Company nor the Trustee nor any Paying Agent nor any Authenticating
Agent nor any Debenture Registrar shall be affected by any notice to the
contrary.

      SECTION 10.4. CERTAIN DEBENTURES OWNED BY COMPANY DISREGARDED. In
determining whether the holders of the requisite aggregate principal amount of
the Debentures have concurred in any direction, consent or waiver under this
Indenture, the Debentures that are owned by the Company or any other obligor on
the Debentures or by any Person directly or indirectly controlling or controlled
by or under common control with the Company or any other obligor on the
Debentures shall be disregarded and deemed not to be Outstanding for the purpose
of any such determination, except that (a) for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, consent
or waiver, only Debentures that a Responsible Officer of the Trustee actually
knows are so owned shall be so disregarded; and (b) for purposes of this Section
10.4, the Trust shall be deemed not to be controlled by the Company. The
Debentures so owned that have been pledged in good faith may be regarded as
Outstanding for the purposes of this Section 10.4, if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right so to act with
respect to such Debentures and that the pledgee is not a Person directly or
indirectly controlling or controlled by or under direct or indirect common


                                       41
<PAGE>
control with the Company or any such other obligor. In case of a dispute as to
such right, any decision by the Trustee taken upon the advice of counsel shall
be full protection to the Trustee.

      SECTION 10.5. ACTIONS BINDING ON THE FUTURE DEBENTUREHOLDERS. At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
10.1, of the taking of any action by the holders of the majority or percentage
in aggregate principal amount of the Debentures specified in this Indenture in
connection with such action, any holder of a Debenture that is shown by the
evidence to be included in the Debentures the holders of which have consented to
such action may, by filing written notice with the Trustee, and upon proof of
holding as provided in Section 10.2, revoke such action so far as concerns such
Debenture. Except as aforesaid, any such action taken by the holder of any
Debenture shall be conclusive and binding upon such holder and upon all future
holders and owners of such Debenture, and of any Debenture issued in exchange
therefor, on registration of transfer thereof or in place thereof, irrespective
of whether or not any notation in regard thereto is made upon such Debenture.
Any action taken by the holders of the majority or percentage in aggregate
principal amount of the Debentures specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Debentures.

                                   ARTICLE XI.
                             SUPPLEMENTAL INDENTURES

      SECTION 11.1. SUPPLEMENTAL INDENTURES WITHOUT THE CONSENT OF THE
DEBENTUREHOLDERS. In addition to any supplemental indenture otherwise authorized
by this Indenture, the Company and the Trustee may from time to time and at any
time enter into an indenture or indentures supplemental hereto (which shall
conform to the provisions of the Trust Indenture Act as then in effect), without
the consent of the Debentureholders, for one or more of the following purposes:

      (a) to cure any ambiguity, defect, or inconsistency herein, or in the
Debentures;

      (b) to comply with Article X;

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

      (d) to add to the covenants of the Company for the benefit of the holders
of all or any of the Debentures or to surrender any right or power herein
conferred upon the Company;

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

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

      (g) to provide for the issuance of and establish the form and terms and
conditions of the Debentures, to establish the form of any certifications
required to be furnished pursuant to


                                       42
<PAGE>
the terms of this Indenture or of the Debentures, or to add to the rights of the
holders of the Debentures;

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

      (i) to evidence a consolidation or merger involving the Company as
permitted under Section 12.1.

      The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, and to make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee shall
not be obligated to enter into any such supplemental indenture that affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
Any supplemental indenture authorized by the provisions of this Section 11.1 may
be executed by the Company and the Trustee without the consent of the holders of
any of the Debentures at the time Outstanding, notwithstanding any of the
provisions of Section 11.2.

      SECTION 11.2. SUPPLEMENTAL INDENTURES WITH CONSENT OF THE
DEBENTUREHOLDERS. With the consent (evidenced as provided in Section 10.1) of
the holders of not less than a majority in aggregate principal amount of the
Debentures at the time Outstanding, the Company, when authorized by Board
Resolutions, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act as then in effect) for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner not covered by Section 11.1 the rights of the holders of the
Debentures under this Indenture; provided, however, that no such supplemental
indenture shall without the consent of the holders of each Debenture then
Outstanding and affected thereby, (a) extend the fixed maturity of any
Debentures, reduce the principal amount thereof, reduce the rate or extend the
time of payment of interest thereon, or limit the right of a holder of Preferred
Securities to institute and prosecute a Direct Action; or (b) reduce the
aforesaid percentage of Debentures, the holders of which are required to consent
to any such supplemental indenture; provided further, that if the Debentures are
held by the Trust or a trustee of the Trust, such supplemental indenture shall
not be effective until the holders of at least a majority in liquidation
preference of Trust Securities of the Trust shall have consented to such
supplemental indenture; provided further, that if the consent of the holder of
each Outstanding Debenture is required, such supplemental indenture shall not be
effective until each holder of the Trust Securities of the Trust shall have
consented to such supplemental indenture. It shall not be necessary for the
consent of the Debentureholders affected thereby under this Section 11.2 to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such consent shall approve the substance thereof.

      SECTION 11.3. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of any
supplemental indenture pursuant to the provisions of this Article XI, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Indenture of the Trustee, the Company and the holders
of Debentures shall thereafter be determined, exercised and enforced hereunder
subject in all respects to such modifications and amendments, and all the terms
and


                                       43
<PAGE>
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 11.4. THE DEBENTURES AFFECTED BY SUPPLEMENTAL INDENTURES. The
Debentures affected by a supplemental indenture, authenticated and delivered
after the execution of such supplemental indenture pursuant to the provisions of
this Article XI, may bear a notation in form approved by the Company, provided
such form meets the requirements of any exchange upon which the Debentures may
be listed, as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Debentures so modified as to conform, in the
opinion of the Board of Directors of the Company, to any modification of this
Indenture contained in any such supplemental indenture may be prepared by the
Company, authenticated by the Trustee and delivered in exchange for the
Debentures then Outstanding.

      SECTION 11.5. EXECUTION OF SUPPLEMENTAL INDENTURES.

      (a) Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of the Debentureholders
required to consent thereto as aforesaid, the Trustee shall join with the
Company in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated, to enter into such supplemental indenture. The Trustee,
subject to the provisions of Sections 9.1, may receive an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant to this
Article XI is authorized or permitted by, and conforms to, the terms of this
Article XI and that it is proper for the Trustee under the provisions of this
Article XI to join in the execution thereof.

      (b) Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section 11.5, the
Trustee shall transmit by mail, first class postage prepaid, a notice, setting
forth in general terms the substance of such supplemental indenture, to the
Debentureholders as their names and addresses appear upon the Debenture
Register. Any failure of the Trustee to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
supplemental indenture.

                                  ARTICLE XII.
                              SUCCESSOR CORPORATION

      SECTION 12.1. THE COMPANY MAY CONSOLIDATE, ETC. Nothing contained in this
Indenture or in any of the Debentures shall prevent any consolidation or merger
of the Company with or into any other corporation or corporations (whether or
not affiliated with the Company, as the case may be), or successive
consolidations or mergers in which the Company, as the case may be, or its
successor or successors shall be a party or parties, or shall prevent any sale,
conveyance, transfer or other disposition of the property of the Company, as the
case may be, or its successor or successors as an entirety, or substantially as
an entirety, to any other corporation (whether or not affiliated with the
Company, as the case may be, or its successor or successors) authorized to
acquire and operate the same; provided, however, that the Company hereby
covenants and agrees that (a) upon any such consolidation, merger, sale,
conveyance, transfer or


                                       44
<PAGE>
other disposition, the due and punctual payment, in the case of the Company, of
the principal of and interest on all of the Debentures, according to their tenor
and the due and punctual performance and observance of all the covenants and
conditions of this Indenture to be kept or performed by the Company, as the case
may be, shall be expressly assumed, by supplemental indenture (which shall
conform to the provisions of the Trust Indenture Act, as then in effect)
satisfactory in form to the Trustee executed and delivered to the Trustee by the
entity formed by such consolidation, or into which the Company, as the case may
be, shall have been merged, or by the entity which shall have acquired such
property, and the ultimate parent entity of such successor entity expressly
assumes the obligations of the Company under the related Preferred Securities
Guarantee, to the extent the Preferred Securities are then Outstanding; (b) in
case the Company consolidates with or merges into another Person or conveys or
transfers its properties and assets substantially as an entirety to any Person,
the successor Person is organized under the laws of the United States or any
state or the District of Columbia; and (c) immediately after giving effect
thereto, no Event of Default, and no event which, after notice or lapse of time
or both, would become an Event of Default, shall have occurred and be
continuing.

      SECTION 12.2. SUCCESSOR CORPORATION SUBSTITUTED.

      (a) In case of any such consolidation, merger, sale, conveyance, transfer
or other disposition and upon the assumption by the successor corporation, by
supplemental indenture, executed and delivered to the Trustee and satisfactory
in form to the Trustee, of, in the case of the Company, the due and punctual
payment of the principal of and interest on all of the Debentures Outstanding
and the due and punctual performance of all of the covenants and conditions of
this Indenture to be performed by the Company, as the case may be, such
successor corporation shall succeed to and be substituted for the Company, with
the same effect as if it had been named as the Company herein, and thereupon the
predecessor corporation shall be relieved of all obligations and covenants under
this Indenture and the Debentures.

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

      (c) Nothing contained in this Indenture or in any of the Debentures shall
prevent the Company from merging into itself or acquiring by purchase or
otherwise, all or any part of, the property of any other Person (whether or not
affiliated with the Company).

      SECTION 12.3. EVIDENCE OF CONSOLIDATION, ETC. TO TRUSTEE. The Trustee,
subject to the provisions of Section 9.1, may receive an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, sale, conveyance,
transfer or other disposition, and any such assumption, comply with the
provisions of this Article XII.

                                  ARTICLE XIII.
                           SATISFACTION AND DISCHARGE

      SECTION 13.1. SATISFACTION AND DISCHARGE OF INDENTURE. If at any time: (a)
the Company shall have delivered to the Trustee for cancellation all Debentures
theretofore authenticated (other than any Debentures that shall have been
destroyed, lost or stolen and that


                                       45
<PAGE>
shall have been replaced or paid as provided in Section 2.9) and all Debentures
for whose payment money or Governmental Obligations have theretofore been
deposited in trust or segregated and held in trust by the Company (and thereupon
repaid to the Company or discharged from such trust, as provided in Section
13.5); or (b) all such Debentures not theretofore delivered to the Trustee for
cancellation shall have become due and payable, or are by their terms to become
due and payable within one year or are to be called for redemption within one
year under arrangements satisfactory to the Trustee for the giving of notice of
redemption, and the Company shall deposit or cause to be deposited with the
Trustee as trust funds the entire amount in moneys or Governmental Obligations
sufficient, or a combination thereof sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay at maturity or upon
redemption all Debentures not theretofore delivered to the Trustee for
cancellation, including principal and interest due or to become due to such date
of maturity or date fixed for redemption, as the case may be, and if the Company
shall also pay or cause to be paid all other sums payable hereunder by the
Company; then this Indenture shall thereupon cease to be of further effect
except for the provisions of Sections 2.3, 2.7, 2.9, 5.1, 5.2, 5.3, 9.7 and
9.10, that shall survive until the date of maturity or redemption date, as the
case may be, and Sections 9.7 and 13.5, that shall survive to such date and
thereafter, and the Trustee, on demand of the Company and at the cost and
expense of the Company, shall execute proper instruments acknowledging
satisfaction of and discharging this Indenture.

      SECTION 13.2. DISCHARGE OF OBLIGATIONS. If at any time all Debentures not
heretofore delivered to the Trustee for cancellation or that have not become due
and payable as described in Section 13.1 shall have been paid by the Company by
depositing irrevocably with the Trustee as trust funds moneys or an amount of
Governmental Obligations sufficient in the opinion of a nationally recognized
certified public accounting firm to pay at maturity or upon redemption all
Debentures not theretofore delivered to the Trustee for cancellation, including
principal and interest due or to become due to such date of maturity or date
fixed for redemption, as the case may be, and if the Company shall also pay or
cause to be paid all other sums payable hereunder by the Company, then after the
date such moneys or Governmental Obligations, as the case may be, are deposited
with the Trustee, the obligations of the Company under this Indenture shall
cease to be of further effect except for the provisions of Sections 2.3, 2.7,
2.9, 5.1, 5.2, 5.3, 9.7 and 13.5, that shall survive until such Debentures shall
mature and be paid. Thereafter, Sections 9.7 and 13.5 shall survive.

      SECTION 13.3. DEPOSITED MONEYS TO BE HELD IN TRUST. All moneys or
Governmental Obligations deposited with the Trustee pursuant to Sections 13.1 or
13.2 shall be held in trust and shall be available for payment as due, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent), to the holders of the Debentures for the payment or redemption of
which such moneys or Governmental Obligations have been deposited with the
Trustee.

      SECTION 13.4. PAYMENT OF MONEYS HELD BY PAYING AGENTS. In connection with
the satisfaction and discharge of this Indenture, all moneys or Governmental
Obligations then held by any Paying Agent under the provisions of this Indenture
shall, upon demand of the Company,


                                       46
<PAGE>
be paid to the Trustee and thereupon such Paying Agent shall be released from
all further liability with respect to such moneys or Governmental Obligations.

      SECTION 13.5. REPAYMENT TO THE COMPANY. Any monies or Governmental
Obligations deposited with any Paying Agent or the Trustee, or then held by the
Company in trust, for payment of principal of or interest on the Debentures that
are not applied but remain unclaimed by the holders of such Debentures for at
least two years after the date upon which the principal of or interest on such
Debentures shall have respectively become due and payable, shall be repaid to
the Company, as the case may be, on June 30 of each year or (if then held by the
Company) shall be discharged from such trust; and thereupon the Paying Agent and
the Trustee shall be released from all further liability with respect to such
moneys or Governmental Obligations, and the holder of any of the Debentures
entitled to receive such payment shall thereafter, as an unsecured general
creditor, look only to the Company for the payment thereof.

based thereon or otherwise in respect thereof, shall be had against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, either
directly or through the Company or any such 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; it being expressly
understood that this Indenture and the obligations issued hereunder are solely
corporate obligations, and that no such personal liability whatever, shall
attach to, or is or shall be incurred by, the incorporators, stockholders,
officers or directors as such, of the Company or of any predecessor or successor
corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements
contained in this Indenture or in any of the Debentures or implied therefrom;
and that any and all such personal liability of every name and nature, either at
common law or in equity or by constitution or statute, and any and all such
rights and claims against, every such incorporator, stockholder, officer or
director as such, because of the creation of the indebtedness hereby authorized,
or under or by reason of the obligations, covenants or agreements contained in
this Indenture or in any of the Debentures or implied therefrom, are hereby
expressly waived and released as a condition of, and as a consideration for, the
execution of this Indenture and the issuance of such Debentures.

corporation that shall at the time be the lawful sole successor of the Company.

      SECTION 15.3. SURRENDER OF THE COMPANY POWERS. The Company by instrument
in writing executed by appropriate authority of its Board of Directors and
delivered to the Trustee may surrender any of the powers reserved to the
Company, and thereupon such power so surrendered shall terminate both as to the
Company, as the case may be, and as to any successor corporation.

      SECTION 15.4. NOTICES. Except as otherwise expressly provided herein any
notice or demand that by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the holders of Debentures
to or on the Company may be given or served by being deposited first class
postage prepaid in a post-office letterbox addressed (until another address is
filed in writing by the Company with the Trustee), as follows: c/o Stifel
Financial Corp., 501 North Broadway, St. Louis, Missouri 63102, Attention: Chief
Financial Officer. Any notice, election, request or demand by the Company or any
Debentureholder to or upon the Trustee shall be deemed to have been sufficiently
given or made, for all purposes, if given or made in writing at the Corporate
Trust Office of the Trustee.

      SECTION 15.5. GOVERNING LAW. This Indenture and each Debenture shall be
deemed to be a contract made under the internal laws of the State of Missouri
and for all purposes shall be construed in accordance with the laws of said
State.

      SECTION 15.6. TREATMENT OF THE DEBENTURES AS DEBT. It is intended that the
Debentures shall be treated as indebtedness and not as equity for federal income
tax purposes. The provisions of this Indenture shall be interpreted to further
this intention. The Company (with respect to its separate books and records),
the Trustee and, by acceptance of a Debenture, each holder of a Debenture, agree
to treat the Debentures as indebtedness of the Company and not as equity for all
tax (including without limitation, federal income tax) and financial accounting
purposes.

      SECTION 15.7. COMPLIANCE CERTIFICATES AND OPINIONS.

      (a) Upon any application or demand by the Company to the Trustee to take
any action under any of the provisions of this Indenture, the Company shall
furnish to the Trustee an Officers' Certificate stating that all conditions
precedent provided for in this Indenture relating to the proposed action have
been complied with and an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent have been complied with, except that in
the case of any such application or demand as to which the furnishing of such
documents is specifically required by any provision of this Indenture relating
to such particular application or demand, no additional certificate or opinion
need be furnished.

      (b) Each certificate or opinion of the Company provided for in this
Indenture and delivered to the Trustee with respect to compliance with a
condition or covenant in this


                                       48
<PAGE>
Indenture shall include (i) a statement that the Person making such certificate
or opinion has read such covenant or condition; (ii) a brief statement as to the
nature and scope of the examination or investigation upon which the statements
or opinions contained in such certificate or opinion are based; (iii) a
statement that, in the opinion of such Person, he or she has made such
examination or investigation as, in the opinion of such Person, is necessary to
enable him or her to express an informed opinion as to whether or not such
covenant or condition has been complied with; and (iv) a statement as to whether
or not, in the opinion of such Person, such condition or covenant has been
complied with; provided, however, that each such certificate shall comply with
the provisions of Section 314 of the Trust Indenture Act.

      SECTION 15.8. PAYMENTS ON BUSINESS DAYS.

      In any case where the date of maturity of interest or principal of any
Debenture or the date of redemption of any Debenture shall not be a Business
Day, then payment of interest or principal may (subject to Section 2.5(b)) be
made on the next succeeding Business Day with the same force and effect as if
made on the nominal date of maturity or redemption, and no interest shall accrue
for the period after such nominal date.

      SECTION 15.9. CONFLICT WITH TRUST INDENTURE ACT.

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

      SECTION 15.10. COUNTERPARTS. This Indenture may be executed in any number
of counterparts, each of which shall be an original, but such counterparts shall
together constitute but one and the same instrument.

      SECTION 15.11. SEPARABILITY. In case any one or more of the provisions
contained in this Indenture or in the Debentures shall for any reason be held to
be invalid, illegal or unenforceable in any respect, such invalidity, illegality
or unenforceability shall not affect any other provisions of this Indenture or
of the Debentures, but this Indenture and the Debentures shall be construed as
if such invalid or illegal or unenforceable provision had never been contained
herein or therein.

      SECTION 15.12. ASSIGNMENT. The Company shall have the right at all times
to assign any of its respective rights or obligations under this Indenture to a
direct or indirect wholly owned Subsidiary of the Company, provided that, in the
event of any such assignment, the Company shall remain liable for all such
obligations. Subject to the foregoing, this Indenture is binding upon and inures
to the benefit of the parties thereto and their respective successors and
assigns. This Indenture may not otherwise be assigned by the parties thereto.

      SECTION 15.13. ACKNOWLEDGMENT OF RIGHTS; RIGHT OF SETOFF.

      (a) The Company acknowledges that, with respect to any Debentures held by
the Trust or a trustee of the Trust, if the Property Trustee fails to enforce
its rights under this Indenture as the holder of the Debentures held as the
assets of the Trust, any holder of Preferred


                                       49
<PAGE>
Securities may institute legal proceedings directly against the Company to
enforce such Property Trustee's rights under this Indenture without first
instituting any legal proceedings against such Property Trustee or any other
person or entity. Notwithstanding the foregoing, and notwithstanding the
provisions of Section 7.4(a) hereof, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Company to pay
principal or interest on the Debentures on the date such principal or interest
is otherwise payable (or in the case of redemption, on the redemption date), the
Company acknowledges that a holder of Preferred Securities may directly
institute a proceeding for enforcement of payment to such holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Preferred Securities of such holder on
or after the respective due date specified in the Debentures.

      (b) Notwithstanding anything to the contrary contained in this Indenture,
the Company shall have the right to setoff any payment it is otherwise required
to make hereunder in respect of any Trust Securities to the extent that the
Company has previously made, or is concurrently making, a payment to the holder
of such Trust Securities under the Preferred Securities Guarantee or in
connection with a proceeding for enforcement of payment of the principal of or
interest on the Debentures directly brought by holders of any Trust Securities.

                                  ARTICLE XVI.
                         SUBORDINATION OF THE DEBENTURES

      SECTION 16.1. AGREEMENT TO SUBORDINATE. The Company covenants and agrees,
and each holder of the Debentures issued hereunder by such holder's acceptance
thereof likewise covenants and agrees, that all the Debentures shall be issued
subject to the provisions of this Article XVI; and each holder of a Debenture,
whether upon original issue or upon transfer or assignment thereof, accepts and
agrees to be bound by such provisions. The payment by the Company of the
principal of and interest on all the Debentures issued hereunder shall, to the
extent and in the manner hereinafter set forth, be subordinated and junior in
right of payment to the prior payment in full of all Senior Debt, Subordinated
Debt and Additional Senior Obligations of the Company (collectively, "Senior
Indebtedness") to the extent provided herein, whether outstanding at the date of
this Indenture or thereafter incurred. No provision of this Article XVI shall
prevent the occurrence of any default or Event of Default hereunder.

      SECTION 16.2. DEFAULT ON SENIOR INDEBTEDNESS. Upon the occurrence and any
continuation of any default by the Company in the payment of principal, premium,
interest or any other payment due on any Senior Indebtedness, or in the event
that the maturity of any Senior Indebtedness has been accelerated because of
such a default, or in the event of the commencement of a judicial proceeding
with regard to such an alleged default or event of default, then, in any case,
no payment shall be made by the Company with respect to the principal (including
redemption payments) of or interest on the Debentures. In the event that,
notwithstanding the foregoing, any payment shall be received by the Trustee when
such payment is prohibited by the preceding sentence of this Section 16.2, such
payment shall be held in trust for the benefit of, and shall be paid over or
delivered to, the holders of Senior Indebtedness or their respective
representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Indebtedness may have been issued, as their respective
interests may


                                       50
<PAGE>
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 ninety (90) days after 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 the Senior Indebtedness.

      SECTION 16.3. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

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

      (b) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee before all Senior Indebtedness 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, as the case may be,
remaining unpaid to the extent necessary to pay such Senior Indebtedness in full
in money in accordance with its terms, after giving effect to any concurrent
payment or distribution to or for the benefit of the holders of such Senior
Indebtedness.

      (c) For purposes of this Article XVI, 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


                                       51
<PAGE>
XVI with respect to the Debentures to the payment of all Senior Indebtedness, as
the case may be, that may at the time be outstanding, provided that (i) such
Senior Indebtedness is assumed by the new corporation, if any, resulting from
any such reorganization or readjustment; and (ii) the rights of the holders of
such Senior Indebtedness are not, without the consent of such holders, altered
by such reorganization or readjustment. The consolidation of the Company with,
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 XII shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 16.3 if such other corporation shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article
XII. Nothing in Section 16.2 or in this Section 16.3 shall apply to claims of,
or payments to, the Trustee under or pursuant to Section 9.7.

      SECTION 16.4. SUBROGATION.

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

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

      (c) Upon any payment or distribution of assets of the Company referred to
in this Article XVI, the Trustee, subject to the provisions of Article IX, and
the holders of the


                                       52
<PAGE>
Debentures shall be entitled to conclusively rely upon any order or decree made
by any court of competent jurisdiction in which such dissolution, winding-up,
liquidation or reorganization proceedings are pending, or a certificate of the
receiver, trustee in bankruptcy, liquidation trustee, agent or other Person
making such payment or distribution, delivered to the Trustee or to the holders
of the Debentures, for the purposes of ascertaining the Persons entitled to
participate in such distribution, the holders of Senior Indebtedness and other
indebtedness of the Company, as the case may be, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article XVI.

      SECTION 16.5. THE TRUSTEE TO EFFECTUATE SUBORDINATION. Each holder of
Debentures by such holder's acceptance thereof authorizes and directs the
Trustee on such holder's behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article XVI and
appoints the Trustee such holder's attorney-in-fact for any and all such
purposes.

      SECTION 16.6. NOTICE BY THE COMPANY.

      (a) The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of the Debentures
pursuant to the provisions of this Article XVI. Notwithstanding the provisions
of this Article XVI or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts that would prohibit
the making of any payment of monies to or by the Trustee in respect of the
Debentures pursuant to the provisions of this Article XVI, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a holder or holders of Senior Indebtedness or from any
trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Section 9.1, shall be entitled in all
respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the notice provided for in this Section 16.6 at
least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of or interest on any Debenture), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purposes for which
they were received, and shall not be affected by any notice to the contrary that
may be received by it within two Business Days prior to such date.

      (b) The Trustee, subject to the provisions of Section 9.1, 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 (or
a trustee on behalf of such holder) to establish that such notice has been given
by a holder of such Senior Indebtedness or a trustee on behalf of any such
holder or holders. In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of such Senior Indebtedness to participate in any payment or distribution
pursuant to this Article XVI, 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


                                       53
<PAGE>
the rights of such Person under this Article XVI, 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 16.7. RIGHTS OF THE TRUSTEE; HOLDERS OF THE SENIOR INDEBTEDNESS.

      (a) The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XVI in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder. The Trustee's right to compensation and reimbursement
of expenses as set forth in Section 9.7 shall not be subject to the
subordination provisions of this Article XVI.

      (b) With respect to the holders of the Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article XVI, and no implied covenants or
obligations with respect to the holders of such Senior Indebtedness shall be
read into this Indenture against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of such Senior Indebtedness and, subject
to the provisions of Section 9.1, the Trustee shall not be liable to any holder
of such Senior Indebtedness if it shall pay over or deliver to holders of
Debentures, the Company or any other Person money or assets to which any holder
of such Senior Indebtedness shall be entitled by virtue of this Article XVI or
otherwise.

      SECTION 16.8. SUBORDINATION MAY NOT BE IMPAIRED.

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

      (b) Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the holders of the
Debentures, without incurring responsibility to the holders of the Debentures
and without impairing or releasing the subordination provided in this Article
XVI or the obligations hereunder of the holders of the Debentures to the holders
of such Senior Indebtedness, do any one or more of the following: (i) 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; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing such Senior Indebtedness; (iii) release any Person liable in any manner
for the collection of such Senior Indebtedness; and (iv) exercise or refrain
from exercising any rights against the Company and any other Person.

                                    DUE 2032

      Stifel Financial Corp., a Delaware corporation (the "Company," which term
includes any successor corporation under the Indenture hereinafter referred to),
for value received, hereby promises to pay to Wilmington Trust Company, as
Property Trustee for Stifel Financial Capital Trust I, or registered assigns,
the principal sum of Thirty Million Nine Hundred Twenty-Seven Thousand Nine
Hundred Dollars ($30,927,900) on June 30, 2032 (the "Stated Maturity"), and to
pay interest on said principal sum from June 30, 2002, 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 March 31, June 30, September 30 and December 31
of each year commencing September 30, 2002, at the rate of 9.00% per annum until
the principal hereof shall have become due and payable, and on any overdue

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. The amount of interest for any partial period
shall be computed on the basis of the number of days elapsed in 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 shall 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, payment of such
interest will be made on the immediately preceding business day, in each case,
with the same force and effect as if made on such date. The interest installment
so payable, and punctually paid or duly provided for, on any Interest Payment
Date shall, as provided in the Indenture, be paid to the person in whose name
this Debenture (or one or more Predecessor Debentures, 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 unless otherwise provided in the
Indenture. 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 Debenture
(or one or more Predecessor Debentures) 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 thereof shall be fixed by the Trustee for the payment
of such defaulted interest, notice thereof shall be given to the registered


                                      A-1
<PAGE>
holders of the Debentures not less than ten (10) days prior to such special
record date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange or quotation
system on or in which the Debentures may be listed or quoted, and upon such
notice as may be required by such exchange, all as more fully provided in the
Indenture. The principal of and the interest on this Debenture shall be payable
at the office or agency of the Trustee 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 Debenture Register.
Notwithstanding the foregoing, so long as the holder of this Debenture is the
Property Trustee, the payment of the principal of and interest on this Debenture
shall be made at such place and to such account as may be designated by the
Trustee.

      The Stated Maturity may be shortened at any time by the Company to any
date not earlier than June 30, 2007.

      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 (as defined in the Indenture). 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 acknowledge or
effectuate the subordination so provided; and (c) appoints the Trustee his or
her attorney-in-fact for any and all such purposes. Each holder hereof, by his
or her 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.

      This Debenture shall not be entitled to any benefit under the Indenture
hereinafter referred to, 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 Debenture 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.

                  9.00% JUNIOR SUBORDINATED DEBENTURE DUE 2032

                                   (CONTINUED)

      This Debenture is one of the subordinated debentures of the Company
(herein sometimes referred to as the "Debentures"), all issued or to be issued
under and pursuant to an Indenture dated as of April 23, 2002 (the
"Indenture") duly executed and delivered between the Company and Wilmington
Trust Company, as Trustee (the "Trustee"), 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 Company and the holders of
the Debentures. The Debentures are limited in aggregate principal amount as
specified in the Indenture.

      Because of the occurrence and continuation of a Special Event (as defined
in the Indenture), in certain circumstances, this Debenture may become due and
payable at the principal amount together with any interest accrued thereon (the
"Redemption Price"). The Redemption Price shall be paid prior to 12:00 noon
Eastern Standard Time, on the date of such redemption or at such earlier time as
the Company determines. The Company shall have the right as set forth in the
Indenture to redeem this Debenture at the option of the Company, without premium
or penalty, in whole or in part at any time on or after June 30, 2007 (an
"Optional Redemption"), 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 hereof plus any accrued but unpaid interest hereon, to the date
of such redemption. Any redemption pursuant to this paragraph shall be made upon
not less than thirty (30) days' nor more than sixty (60) days' notice, at the
Redemption Price. The Redemption Price shall be paid at the time and in the
manner provided therefor in the Indenture. If the Debentures are only partially
redeemed by the Company pursuant to an Optional Redemption, the Debentures shall
be redeemed pro rata or by lot or by any other method utilized by the Trustee as
described in the Indenture. In the event of an Optional Redemption of this
Debenture in part only, a new Debenture or Debentures for the unredeemed portion
hereof shall 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 Company and the Trustee,
with the consent of the holders of not less than a majority in aggregate
principal amount of the Debentures at the time Outstanding (as defined 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 Debentures; provided, however, that no such
supplemental indenture shall, except as provided in the Indenture, (i) extend
the fixed maturity of the Debentures, reduce the principal amount thereof, or
reduce the rate or extend the time of payment of interest thereon without the
consent of the holder of each Debenture so affected


                                      A-5
<PAGE>
thereby; or (ii) reduce the aforesaid percentage of the Debentures, the holders
of which are required to consent to any such supplemental indenture, without the
consent of the holder of each Debenture then Outstanding and so affected
thereby. The Indenture also contains provisions permitting the holders of at
least a majority in aggregate principal amount of the Debentures at the time
Outstanding, on behalf of all of the holders of the Debentures, 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 the payment of the principal of or interest on any of the
Debentures. 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 Company, which is
absolute and unconditional, to pay the principal and interest on this Debenture
at the time and place and at the rate and in the manner herein prescribed.

      The Company, as further described in the Indenture, shall have the right
at any time during the term of the Debentures and from time to time to defer
payments of interest by extending the interest payment period of such Debentures
for up to twenty (20) consecutive quarters (each, an "Extension Period"), at the
end of which period the Company shall pay all interest then accrued (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 Extension Period, so long as no Event of Default shall
have occurred and be continuing, the Company may further extend such Extension
Period, provided that such Extension Period together with all such further
extensions thereof shall not exceed twenty (20) consecutive quarters, extend
beyond June 30, 2032, or end on a date other than an Interest Payment Date. At
the termination of any such Extension Period and upon the payment of all
Deferred Payments then due, the Company may commence a new Extension 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
Debenture Register (as defined in the Indenture) of the Company, upon surrender
of this Debenture for registration of transfer at the office or agency of the
Trustee 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 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 shall be issued to the designated transferee or
transferees. No service charge shall be made for any such 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 Debenture,
the Company, the Trustee, any Paying Agent (as defined in the Indenture) and the
Debenture Registrar may deem and treat the registered holder hereof as the
absolute owner hereof (whether or not this


                                      A-6
<PAGE>
Debenture shall be overdue and notwithstanding any notice of ownership or
writing hereon made by anyone other than the Debenture Registrar) 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 the
Trustee nor any Paying Agent nor any Debenture 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 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 Debentures are issuable only in registered form without coupons in
denominations of $25 and any integral multiple thereof (or such other
denominations and any integral multiple thereof as may be deemed necessary by
the Company for the purpose of maintaining the eligibility of the Debentures for
listing on the New York Stock Exchange or any successor thereto).

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