               TEXAS UTILITIES COMPANY DOING BUSINESS AS TXU CORP
                              OFFICER'S CERTIFICATE

     Kirk R. Oliver, the Treasurer of Texas Utilities Company doing business as
TXU Corp (the "Company"), pursuant to the authority granted in the Board
Resolutions of the Company, dated May 14, 1999, and Sections 201 and 301 of the
Indenture defined herein, does hereby certify to The Bank of New York (the
"Trustee"), as Trustee under the Indenture (For Unsecured Subordinated Debt
Securities relating to Trust Securities) of the Company dated as of December 1,
1998 (the "Indenture") that:

     1.   The securities of the second series to be issued under the Indenture
          shall be designated "8.70% Junior Subordinated Debentures, Series B"
          (the "Debentures of the Second Series"). The Debentures of the Second
          Series are to be issued to The Bank of New York, as Property Trustee
          (the "Property Trustee") of TXU Capital II, a Delaware statutory
          business trust (the "Trust"). All capitalized terms used in this
          certificate which are not defined herein but are defined in the
          Indenture shall have the meanings set forth in the Indenture;

     2.   The Debentures of the Second Series shall be limited in aggregate
          principal amount to $170,103,125 at any time Outstanding, except as
          contemplated in Section 301(b) of the Indenture;

     3.   The Debentures of the Second Series shall mature and the principal
          shall be due and payable together with all accrued and unpaid interest
          thereon on December 31, 2034 except as provided in paragraph (8) of
          this Certificate;

     4.   The Debentures of the Second Series shall bear interest from, and
          including, the date of original issuance, at the rate of 8.70% per
          annum, payable quarterly in arrears on March 31, June 30, September 30
          and December 31 of each year (each, an "Interest Payment Date")
          commencing March 31, 2000. With respect to the Debentures of the
          Second Series, the term "Interest Period" shall mean each period from,
          and including, an Interest Payment Date to, but excluding, the next
          succeeding Interest Payment Date, except that the first Interest
          Period shall commence on the date of original issuance. The amount of
          interest payable for any Interest Period will be computed on the basis
          of a 360-day year of twelve 30-day months. Interest on the Debentures
          of the Second Series will accrue from, and including, the date of
          original issuance, but if interest has been paid on such Debentures of
          the Second Series, then from the most recent Interest Payment Date to
          which interest has been paid or duly provided for. In the event that
          any Interest Payment Date is not a Business Day, then payment of
          interest payable on such date will be made on the next succeeding day
          which is a Business Day (and without any interest or other payment in
          respect of such delay), in each case with the same force and effect as
          if made on such Interest Payment Date;

     5.   Each installment of interest on a Debenture of the Second Series shall
          be payable to the Person in whose name such Debenture of the Second
          Series is registered in the Securities Register on the fifteenth day
<PAGE>

          (whether or not a Business Day) preceding the corresponding Interest
          Payment Date (the "Regular Record Date") for the Debentures of the
          Second Series; provided, however, that if the Debentures of the Second
          Series are held by a securities depositary in a book-entry only form,
          the Regular Record Date will be one Business Day preceding the
          corresponding Interest Payment Date; and provided, further, that the
          Company shall have the right to change the Regular Record Date by one
          or more Officer's Certificates. Any installment of interest on the
          Debentures of the Second Series not punctually paid or duly provided
          for shall forthwith cease to be payable to the Holders of such
          Debentures of the Second Series on such Regular Record Date, and may
          be paid to the Persons in whose name the Debentures of the Second
          Series are registered in the Securities Register at the close of
          business on a Special Record Date to be fixed by the Trustee for the
          payment of such Defaulted Interest. Notice of such Defaulted Interest
          and Special Record Date shall be given to the Holders of the
          Debentures of the Second Series not less than 10 days prior to such
          Special Record Date in any lawful manner not inconsistent with the
          requirements of any securities exchange on which such Debentures of
          the Second Series may be listed, and upon such notice as may be
          required by such exchange, all as more fully provided in the
          Indenture;

     6.   The principal and each installment of interest on the Debentures of
          the Second Series shall be payable at, and registration and
          registration of transfers and exchanges in respect of the Debentures
          of the Second Series may be effected at, the office or agency of the
          Company in The City of New York; provided that payment of interest may
          be made at the option of the Company by check mailed to the address of
          the persons entitled thereto as such addresses appear in the
          Securities Register. Notices and demands to or upon the Company in
          respect of the Debentures of the Second Series may be served at such
          office or agency of the Company in The City of New York. The Corporate
          Trust Office of the Trustee will initially be the agency of the
          Company for such payment, registration and registration of transfers
          and exchanges and services of notices and demands, and the Company
          hereby appoints the Trustee as its agent for all such purposes;
          provided, however, that the Company reserves the right to change, by
          one or more Officer's Certificates, any such office or agency and such
          agent. The Trustee will be the Security Registrar and the Paying Agent
          for the Debentures of the Second Series;

     7.   The Debentures of the Second Series will be redeemable at the option
          of the Company on or after December 31, 2004, at any time in whole and
          from time to time in part, upon not less than 30 nor more than 60
          days' notice given as provided in the Indenture, at a Redemption Price
          equal to 100% of the principal amount thereof plus accrued and unpaid
          interest thereon to the Redemption Date.

          If at any time a Tax Event (as defined below) shall occur and be
          continuing and either (i) in the opinion of counsel to the Company
          experienced in such matters, there would in all cases, after effecting
          the termination of the Trust, after satisfaction of liabilities to
          creditors of the Trust, if any, as provided by applicable law, and the

                                       2
<PAGE>

          distribution of the Debentures of the Second Series to the holders of
          the Preferred Trust Securities issued by the Trust (the "Preferred
          Trust Securities"), in exchange therefor, be more than an
          insubstantial risk that an Adverse Tax Consequence (as defined below)
          would continue to exist or (ii) the Debentures of the Second Series
          are not held by the Trust, then the Company shall have the right to
          redeem the Debentures of the Second Series, in whole but not in part,
          at any time within 90 days following the occurrence of the Tax Event,
          at 100% of the principal amount thereof plus accrued and unpaid
          interest thereon to the Redemption Date.

          "Tax Event" means the receipt by the Trust or the Company of an
          opinion of counsel experienced in such matters to the effect that, as
          a result of (a) any amendment to, clarification of, or change
          (including any announced prospective change) in, the laws or treaties
          (or any regulations thereunder) of the United States or any political
          subdivision or taxing authority thereof or therein affecting taxation,
          (b) any judicial decision or any official administrative
          pronouncement, ruling, regulatory procedure, notice or announcement
          (including any notice or announcement of intent to issue or adopt any
          such administrative pronouncement, ruling, regulatory procedure or
          regulation) (each, an "Administrative Action"), or (c) any amendment
          to, clarification of, or change in the official position or the
          interpretation of any such Administrative Action or judicial decision
          or any interpretation or pronouncement that provides for a position
          with respect to such Administrative Action or judicial decision that
          differs from the theretofore generally accepted position, in each case
          by any legislative body, court, governmental authority or regulatory
          body, irrespective of the time or manner in which such amendment,
          clarification or change is introduced or made known, which amendment,
          clarification, or change is effective, which Administrative Action is
          taken or which judicial decision is issued, in each case on or after
          the date of issuance of the Preferred Trust Securities, there is more
          than an insubstantial risk that (i) the Trust is, or will be, subject
          to United States federal income tax with respect to interest received
          on the Debentures of the Second Series, (ii) interest payable by the
          Company on the Debentures of the Second Series is not, or will not be,
          fully deductible by the Company for United States federal income tax
          purposes, or (iii) the Trust is, or will be, subject to more than a de
          minimis amount of other taxes, duties or other governmental charges
          (each of the circumstances described in clauses (i), (ii) or (iii)
          being an "Adverse Tax Consequence");

     8.   Upon the occurrence and during the continuation of a Tax Event
          relating to non-deductibility of interest payments on the Debentures
          of the Second Series, in lieu of redeeming the Debentures of the
          Second Series, at its option, the Company may shorten the Stated
          Maturity of the Debentures of the Second Series to a date not earlier
          than December 13, 2014. The Trustee may conclusively rely on an
          Officer's Certificate setting forth a changed Stated Maturity of the
          Debentures of the Second Series;

                                       3
<PAGE>

     9.   So long as any Debentures of the Second Series are Outstanding, the
          failure of the Company to pay interest on any Debentures of the Second
          Series within 30 days after the same becomes due and payable (whether
          or not payment is prohibited by the provisions of Article Fifteen of
          the Indenture) shall constitute an Event of Default; provided,
          however, that a valid extension of the interest payment period by the
          Company as contemplated in Section 311 of the Indenture and paragraph
          (10) of this Certificate shall not constitute a failure to pay
          interest for this purpose;

     10.  Pursuant to Section 311 of the Indenture, the Company shall have the
          right, at any time and from time to time during the term of the
          Debentures of the Second Series, so long as the Company is not in
          default in the payment of interest on the Securities of any series
          under the Indenture, to extend the interest payment period to a period
          not exceeding 20 consecutive quarterly periods (an "Extension Period")
          during which period interest (calculated for each Interest Period in
          the manner provided for in paragraph (4) of this Certificate, as if
          the interest payment period had not been so extended) will be
          compounded quarterly. At the end of the Extension Period, the Company
          shall pay all interest accrued and unpaid (together with interest
          thereon at the rate specified for the Debentures of the Second Series,
          compounded quarterly, to the extent permitted by applicable law).
          However, during any such Extension Period, the Company shall not
          declare or pay any dividend or distribution (other than a dividend or
          distribution in common stock of the Company) on, or redeem, purchase,
          acquire or make a liquidation payment with respect to, any of its
          capital stock, repurchase or redeem any indebtedness that is pari
          passu with or subordinated to the Debentures of the Second Series, or
          make any guarantee payments with respect to the foregoing ("Restricted
          Payments"). The restrictions contained in the immediately preceding
          sentence shall not apply to a Subsidiary who assumes the obligations
          of the Company under the Indenture and under the Debentures of the
          Second Series, pursuant to paragraph (16) of this Certificate.

          Prior to the termination of any such Extension Period, the Company may
          further extend the interest payment period, provided that such
          Extension Period together with all such previous and further
          extensions thereof shall not exceed 20 consecutive quarterly periods
          at any one time or extend beyond the Maturity of the Debentures of the
          Second Series. Any Extension Period with respect to payment of
          interest on the Debentures of the Second Series, or any extended
          interest payment period in respect of similar securities will apply to
          the Debentures of the Second Series and all such securities and will
          also apply to distributions with respect to the Preferred Trust
          Securities and all other securities with terms substantially the same
          as the Preferred Trust Securities. Upon the termination of any such
          Extension Period and the payment of all amounts then due, including
          interest on deferred interest payments, the Company may elect to begin
          a new Extension Period, subject to the above requirements. No interest
          shall be due and payable during an Extension Period, except at the end
          thereof. The Company will give the Trust and the Trustee notice of its
          election of an Extension Period before the Business Day prior to the

                                       4
<PAGE>

          record date for the distribution which would occur but for such
          election and will cause the Trust to send notice of such election to
          the holders of Preferred Trust Securities;

     11.  At any time, the Company will have the right to dissolve the Trust
          and, after satisfaction of liabilities to creditors, if any, of the
          Trust as provided by applicable law, cause the Debentures of the
          Second Series to be distributed to the holders of the Preferred Trust
          Securities;

     12.  So long as any Securities are outstanding under the Indenture, the
          Company shall not make any Restricted Payments at any time the Company
          is in default under the Guarantee with respect to the Trust or is in
          default with respect to payments due on any Outstanding Securities;

     13.  In the event that, at any time subsequent to the initial
          authentication and delivery of the Debentures of the Second Series,
          the Debentures of the Second Series are to be held in global form by a
          securities depositary, the Company may at such time establish the
          matters contemplated in clause (r) in the second paragraph of Section
          301 of the Indenture in an Officer's Certificate supplemental to this
          Certificate;

     14.  No service charge shall be made for the registration of transfer or
          exchange of the Debentures of the Second Series; provided, however,
          that the Company may require payment of a sum sufficient to cover any
          tax or other governmental charge that may be imposed in connection
          with the exchange or transfer;

     15.  If the Company shall make any deposit of money and/or Government
          Obligations with respect to any Debentures of the Second Series, or
          any portion of the principal amount thereof, as contemplated by
          Section 701 of the Indenture, the Company shall not deliver an
          Officer's Certificate described in clause (z) in the first paragraph
          of said Section 701 unless the Company shall also deliver to the
          Trustee, together with such Officer's Certificate, either:

               (A) an instrument wherein the Company, notwithstanding the
          satisfaction and discharge of its indebtedness in respect of the
          Debentures of the Second Series, shall assume the obligation (which
          shall be absolute and unconditional) to irrevocably deposit with the
          Trustee or Paying Agent such additional sums of money, if any, or
          additional Government Obligations (meeting the requirements of Section
          701), if any, or any combination thereof, at such time or times, as
          shall be necessary, together with the money and/or Government
          Obligations theretofore so deposited, to pay when due the principal of
          and premium, if any, and interest due and to become due on such
          Debentures of the Second Series or portions thereof, all in accordance
          with and subject to the provisions of said Section 701; provided,
          however, that such instrument may state that the obligation of the
          Company to make additional deposits as aforesaid shall be subject to
          the delivery to the Company by the Trustee of a notice asserting the
          deficiency accompanied by an opinion of an independent public

                                       5
<PAGE>

          accountant of nationally recognized standing, selected by the Trustee,
          showing the calculation thereof; or

               (B) an Opinion of Counsel, based on a change in law occurring
          after the date of this certificate, to the effect that the Holders of
          such Debentures of the Second Series, or portions of the principal
          amount thereof, will not recognize income, gain or loss for United
          States federal income tax purposes as a result of the satisfaction and
          discharge of the Company's indebtedness in respect thereof and will be
          subject to United States federal income tax on the same amounts, at
          the same times and in the same manner as if such satisfaction and
          discharge had not been effected;

     16.  The obligations of the Company under the Debentures of the Second
          Series and under the Indenture will be subject to assignment by the
          Company to and assumption by a wholly owned Subsidiary of the Company
          at any time, as provided in the form set forth in Exhibit A hereto
          with respect to the Debentures of the Second Series.

          In the event that such Subsidiary assumes the obligations under the
          Debentures of the Second Series, the Company will unconditionally
          guarantee payment of the Debentures of the Second Series and will
          execute a guarantee in form and substance satisfactory to the Trustee.
          Pursuant to the guarantee, the Company will remain fully and
          unconditionally liable for the payment obligations of such assuming
          Subsidiary under the Debentures of the Second Series and under the
          Indenture, including, without limitation, payment, as and when due, of
          the principal of, premium, if any, and interest on, the Debentures of
          the Second Series. and payment of additional amounts, if any, as
          provided in this paragraph (16). Under such guarantee, the Company
          will also not be able to make Restricted Payments during any Extension
          Period with respect to the Debentures of the Second Series. Other than
          the obligation to make such payments, and the limitation on the
          Restricted Payments and payments to the Trustee under Section 907 of
          the Indenture, the Company will be released and discharged from all of
          its other obligations under the Indenture. The foregoing assignment
          and assumption shall be in compliance with applicable law including
          the Securities Act of 1933.

          If the Company assigns its obligations under the Debentures of the
          Second Series to a Subsidiary, the guarantee will provide that if
          there is an Event of Default and the Holders are prevented by
          applicable law from exercising their rights to accelerate the maturity
          of the Debentures of the Second Series, to collect interest on the
          Debentures of the Second Series, or to enforce any other right or
          remedy with respect to the Debentures of the Second Series, the
          Company will pay, upon demand, the amount that would otherwise have
          been due and payable had the exercise of such rights and remedies been
          permissible.

          If the Company assigns its obligations under the Debentures of the
          Second Series to a Subsidiary that is organized in a foreign
          jurisdiction all payments made by such foreign Subsidiary on the
          Debentures of the Second Series shall be made without withholding or

                                       6
<PAGE>

          deduction for any foreign taxes or other foreign governmental charges
          imposed with respect to payments on the Debentures of the Second
          Series, unless such withholding or deduction is required by law. If
          any such withholding or deduction is made, such foreign Subsidiary
          shall pay to each Holder of Debentures of the Second Series additional
          amounts as may be necessary so that the net amount received by the
          Holder of the Debentures of the Second Series after the withholding or
          deduction equals the amount that the Holder of the Debentures of the
          Second Series would have received in the absence of such withholding
          or deduction, after any additional taxes or other charges payable by
          such foreign Subsidiary in respect of these additional amounts, except
          that no such additional amounts shall be payable:

               (A) to or for a Holder who is liable for those foreign taxes or
          charges because of the Holder's connection with the relevant
          jurisdiction, whether as a citizen, a resident or a national of the
          jurisdiction or because the Holder carries on a business or maintains
          a permanent establishment there or is physically present there;

               (B) to or for a Holder who presents a Debenture of the Second
          Series required to be presented for payment more than 30 days after
          the date on which payment first becomes due, unless that Holder would
          have been entitled to such additional amounts by presenting such
          security during the 30 day period;

               (C) to or for a Holder who presents a Debenture of the Second
          Series, where presentation is required, at any place other than in The
          City of New York, unless the Company does not provide a place for
          presentation within The City of New York;

               (D) to or for a Holder who is liable for the tax or charge
          because the Holder failed to take appropriate and available steps to
          declare non-residence or request exemption from the relevant tax
          authority; or

          No additional amounts will be payable with respect to any Debenture of
          the Second Series if the beneficial owner would not have been entitled
          to such payment if that beneficial owner had been a Holder;

     17.  The Trustee, the Security Registrar and the Company will have no
          responsibility under the Indenture for transfers of beneficial
          interests in the Debentures of the Second Series;

     18.  The Debentures of the Second Series shall have such other terms and
          provisions as are provided in the form thereof set forth in Exhibit A
          hereto, and shall be issued in substantially such form;

          thereto, relating to the issuance of the Debentures of the Second

                 [FORM OF FACE OF JUNIOR SUBORDINATED DEBENTURE]

               TEXAS UTILITIES COMPANY DOING BUSINESS AS TXU CORP

                 8.70% JUNIOR SUBORDINATED DEBENTURES, SERIES B

          TEXAS UTILITIES COMPANY doing business as TXU CORP, a corporation duly
organized and existing under the laws of the State of Texas (herein referred to
as the "Company", which term includes any successor Person under the Indenture
referred to on the reverse hereof), for value received, hereby promises to pay
to ____________________________________, or registered assigns, the principal
sum of ____________________ Dollars ($ __________) on December 31, 2034 (except
as hereinafter provided) and, except as hereinafter provided, to pay interest on
said principal sum, from and including the date of original issuance, but if
interest has been paid on this Security, then from, and including, the most
recent Interest Payment Date to which interest has been paid or duly provided
for, quarterly in arrears on March 31, June 30, September 30 and December 31 of
each year (each an "Interest Payment Date"), commencing March 31, 2000, at the
rate of 8.70% per annum, plus Additional Interest, if any, until the principal
hereof is paid or made available for payment. The amount of interest payable on
any Interest Payment Date shall be computed on the basis of a 360-day year of
twelve 30-day months. In the event that any Interest Payment Date is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of such delay), in each case with the same force and effect
as if made on such Interest Payment Date. The interest so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on
the Regular Record Date for such interest, which shall be the fifteenth day
(whether or not a Business Day) preceding such Interest Payment Date; provided,
however, that if the Securities of this series are held by a securities
depositary in a book-entry only form, the Regular Record Date will be one
Business Day preceding the corresponding Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in the Indenture.

          Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in The City of New York, the State of New York, in such coin or currency
of the United States of America as at the time of payment is legal tender for
payment of public and private debts, provided, however, that, at the option of

                                       10
<PAGE>

the Company, interest on this Security may be paid by check mailed to the
address of the person entitled thereto, as such address shall appear on the
Security Register.

          Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

          Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

          IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

               [FORM OF REVERSE OF JUNIOR SUBORDINATED DEBENTURE]

          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture (For Unsecured Subordinated Debt Securities relating
to Trust Securities), dated as of December 1, 1998 (herein, together with any
amendments thereto, called the "Indenture", which term shall have the meaning
assigned to it in such instrument), between the Company and The Bank of New
York, as Trustee (herein called the "Trustee", which term includes any successor
trustee under the Indenture), and reference is hereby made to the Indenture,
including the Board Resolutions and Officer's Certificate filed with the Trustee
on December 13, 1999 (the "Officer's Certificate"), creating the series
designated on the face hereof, for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof, limited in aggregate principal
amount to $170,103,125.

          This Security will be redeemable at the option of the Company on or
after December 31, 2004, at any time in whole and from time to time in part,
upon not less than 30 nor more than 60 days' notice given as provided in the
Indenture, at a Redemption Price equal to 100% of the principal amount thereof
plus accrued and unpaid interest hereon, including Additional Interest, if any,
to the Redemption Date.

          If at any time a Tax Event (as defined below) shall occur and be
continuing and either (i) in the opinion of counsel to the Company experienced
in such matters, there would in all cases, after effecting the termination of
the Trust, after satisfaction of liabilities to creditors of the Trust, if any,
as provided by applicable law, and the distribution of this Security to the
holders of the Preferred Trust Securities of the Trust (the "Preferred Trust
Securities"), in exchange therefor, be more than an insubstantial risk that an
Adverse Tax Consequence (as defined below) would continue to exist or (ii) this
Security is not held by TXU Capital II, a Delaware statutory business trust (the
"Trust"), then the Company shall have the right to redeem this Security, in
whole but not in part, at any time within 90 days following the occurrence of
the Tax Event, at 100% of the principal amount thereof plus accrued and unpaid
interest hereon, including Additional Interest, if any, to the Redemption Date.

          "Tax Event" means the receipt by the Trust or the Company of an
opinion of counsel experienced in such matters to the effect that, as a result
of (a) any amendment to, clarification of, or change (including any announced
prospective change) in, the laws or treaties (or any regulations thereunder) of
the United States or any political subdivision or taxing authority thereof or
therein affecting taxation, (b) any judicial decision or any official
administrative pronouncement, ruling, regulatory procedure, notice or
announcement (including any notice or announcement of intent to issue or adopt
any such administrative pronouncement, ruling, regulatory procedure or
regulation) (each, an "Administrative Action"), or (c) any amendment to,
clarification of, or change in the official position or the interpretation of
any such Administrative Action or judicial decision or any interpretation or
pronouncement that provides for a position with respect to such Administrative
Action or judicial decision that differs from the theretofore generally accepted
position, in each case by any legislative body, court, governmental authority or

                                       12
<PAGE>

regulatory body, irrespective of the time or manner in which such amendment,
clarification or change is introduced or made known, which amendment,
clarification, or change is effective, which Administrative Action is taken or
which judicial decision is issued, in each case on or after the date of issuance
of the Preferred Trust Securities, there is more than an insubstantial risk that
(i) the Trust is, or will be, subject to United States federal income tax with
respect to interest received on this Security, (ii) interest payable by the
Company on this Security is not, or will not be, fully deductible by the Company
for United States federal income tax purposes, or (iii) the Trust is, or will
be, subject to more than a de minimis amount of other taxes, duties or other
governmental charges (each of the circumstances described in clauses (i), (ii)
or (iii) being an "Adverse Tax Consequence").

          Interest installments whose Stated Maturity is on or prior to such
Redemption Date will be payable to the Holder of such Security, or one or more
Predecessor Securities, of record at the close of business on the related
Regular Record Date referred to on the face hereof, all as provided in the
Indenture.

          In the event of redemption of this Security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

          Upon the occurrence and continuation of a Tax Event relating to
non-deductibility of interest payments on the Securities of this series, in lieu
of redeeming the Securities of this series, at its option, the Company may
shorten the Stated Maturity of the Securities of this series to a date not
earlier than December 13, 2014. The Trustee may conclusively rely on an
Officer's Certificate setting forth a changed Stated Maturity of the Securities
of this series.

          The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinated and subject in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto. Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his 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 attorney-in-fact for
any and all such purposes. Each Holder hereof, by his acceptance hereof, hereby
waives all notice of the acceptance of the subordination provisions contained
herein and in the Indenture by each holder of Senior Indebtedness, whether now
outstanding or hereafter incurred, and waives reliance by each such Holder upon
said provisions.

          The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security upon compliance with certain conditions set
forth in the Indenture.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the

                                       13
<PAGE>

consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of all series to be affected. The Indenture contains
provisions permitting the Holders of a majority in aggregate principal amount of
the Securities of all series then Outstanding to waive compliance by the Company
with certain provisions of the Indenture. The Indenture also contains provisions
permitting the Holders of specified percentages in principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

          As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than a majority in aggregate
principal amount of the Securities of all series at the time Outstanding in
respect of which an Event of Default shall have occurred and be continuing shall
have made written request to the Trustee to institute proceedings in respect of
such Event of Default as Trustee and offered the Trustee reasonable indemnity,
and the Trustee shall not have received from the Holders of a majority in
aggregate principal amount of Securities of all series at the time Outstanding
in respect of which an Event of Default shall have occurred and be continuing a
direction inconsistent with such request, and shall have failed to institute any
such proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder of
this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

          Pursuant to Section 311 of the Indenture, so long as the Company is
not in default in the payment of interest on the Securities of any series under
the Indenture, the Company shall have the right, at any time and from time to
time during the term of the Securities of this series, to extend the interest
payment period to a period not exceeding 20 consecutive quarterly periods (an
"Extension Period") during which period interest (calculated for each Interest
Period (as defined in the Officer's Certificate) in the manner provided for in
paragraph (4) of the Officer's Certificate, as if the interest payment period
had not been so extended) will be compounded quarterly. At the end of the
Extension Period, the Company shall pay all interest accrued and unpaid hereon
(together with interest thereon at the rate specified for the Securities of this
series, compounded quarterly, to the extent permitted by applicable law) and
Additional Interest, if any; provided, however, that during any such Extension
Period, the Company shall not declare or pay any dividend or distribution (other
than a dividend or distribution in common stock of the Company) on, or redeem,
purchase, acquire or make a liquidation payment with respect to, any of its

                                       14
<PAGE>

capital stock, make any payment of principal, interest or premium, if any, on or
repay, repurchase or redeem any indebtedness that is pari passu with or
subordinated to the Securities of this series, or make any guarantee payments
with respect to the foregoing ("Restricted Payments"). The restrictions
contained in the proviso to the immediately preceding sentence shall not apply
to a Subsidiary who assumes the obligations of the Company under the Indenture
and under the Securities of this series, pursuant to paragraph (16) of the
Officer's Certificate. Prior to the termination of any such Extension Period,
the Company may further extend the interest payment period, provided that such
Extension Period together with all such previous and further extensions thereof
shall not exceed 20 consecutive quarterly periods at any one time or extend
beyond the Maturity of the Securities of this series. Any Extension Period with
respect to payment of interest on the Securities of this series, or any extended
interest payment period in respect of similar securities (including all
Securities issued under the Indenture) will apply to the Securities of this
series and all such securities and will also apply to distributions with respect
to the Preferred Trust Securities and all other securities with terms
substantially the same as the Preferred Trust Securities. Upon the termination
of any such Extension Period and the payment of all amounts then due, including
interest on deferred interest payments, the Company may elect to begin a new
Extension Period, subject to the above requirements. No interest shall be due
and payable during an Extension Period, except at the end thereof. The Company
shall give the Trustee notice of its election of an Extension Period before the
Business Day prior to the record date for the distribution which would occur but
for such election.

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

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the absolute
owner hereof for all purposes, whether or not this Security be overdue, and
neither the Company, the Trustee nor any such agent shall be affected by notice
to the contrary.

          Unless an Event of Default, or an event which, after notice or lapse
of time or both, would become an Event of Default, shall have occurred and be
continuing, the obligations of the Company under the Securities of this series
and the Indenture may be assigned by the Company to, and be assumed in whole, on
a full recourse basis, by a wholly owned Subsidiary of the Company at any time;
provided, however, that such assumption shall be subject to, and permitted only
upon the fulfillment and satisfaction of, the following terms and conditions:
(a) an assumption agreement and a supplemental indenture to the Indenture
evidencing such assumption shall be in substance and form reasonably
satisfactory to the Trustee and shall, inter alia, include modifications and
amendments to the Indenture making the obligations under the Securities of this
series and under the Indenture primary obligations of such Subsidiary,
substituting such Subsidiary of the Company for the Company in the form of the

                                       15
<PAGE>

Securities of this series and in provisions of the Indenture and releasing and
discharging the Company from its obligations under the Securities of this series
and the Indenture; and (b) the Trustee shall have received (i) an executed
counterpart of such assumption agreement and supplemental indenture; (ii)
evidence satisfactory to the Trustee and the Company that all necessary
authorizations, consents, orders, approvals, waivers, filings and declarations
of or with, Federal, state, county, municipal, regional or other governmental
authorities, agencies or boards (collectively, "Governmental Actions") relating
to such assumption have been duly obtained and are in full force and effect,
(iii) evidence satisfactory to the Trustee that any security interest intended
to be created by the Indenture is not in any material way adversely affected or
impaired by any of the agreements or transactions relating to such assumption
and (iv) an Opinion of Counsel for such Subsidiary, reasonably satisfactory in
substance, scope and form to the Trustee and the Company, to the effect that (A)
the supplemental indenture evidencing such assumption has been duly authorized,
executed and delivered by such Subsidiary, (B) the execution and delivery by
such Subsidiary of such supplemental indenture and the consummation of the
transactions contemplated thereby do not contravene any provision of law or any
governmental rule applicable to such Subsidiary or any provision of such
Subsidiary's charter documents or by-laws and do not contravene any provision
of, or constitute a default under, or result in the creation or imposition of
any lien upon any of such Subsidiary's properties or assets under any indenture,
mortgage, contract or other agreement to which such Subsidiary is a party or by
which such Subsidiary or any of its properties may be bound or affected, (C) all
necessary Governmental Actions relating to such assumption have been duly
obtained and are in full force and effect and (D) such agreement and
supplemental indenture constitute the legal, valid and binding obligations of
such Subsidiary, enforceable in accordance with their respective terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws at the time in effect affecting
the rights of creditors generally.

          At the time of such assumption the Company will unconditionally
guarantee payment of the Securities of this series and will execute a guarantee
in form and substance satisfactory to the Trustee. Pursuant to the guarantee,
the Company will remain fully and unconditionally liable for the payment
obligations of such assuming Subsidiary under the Securities of this series and
under the Indenture, including, without limitation, payment, as and when due, of
the principal of, premium, if any, and interest on, the Securities of this
series and payment of additional amounts, if any, as provided in paragraph (16)
of the Officer's Certificate. Under the guarantee, the Company will also not be
able to make Restricted Payments during any Extension Period with respect to the
Securities of this series. Other than the obligation to make such payments, and
the limitation on the Restricted Payments and payments to the Trustee under
Section 907 of the Indenture, the Company shall be released and discharged from
all other obligations under the Indenture.

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

          any business, activities or transaction except as expressly provided
          herein or contemplated hereby. In particular, the Trustees shall not

          by this Trust Agreement, (ii) sell, assign, transfer, exchange,
          pledge, set-off or otherwise dispose of any of the Trust Property or
          interests therein, including to Securityholders, except as expressly

          fail or cease to qualify as a "grantor trust" for United States
          federal income tax purposes and not as an association taxable as a
          corporation, (iv) incur any indebtedness for borrowed money or (v)
          take or consent to any action that would result in the placement of a

                                       13

          Lien on any of the Trust Property. The Trustees shall defend all
          claims and demands of all Persons at any time claiming any Lien on any
          of the Trust Property adverse to the interest of the Trust or the
          Securityholders in their capacity as Securityholders.

               (c) In connection with the issue of the Preferred Trust
          Securities, the Depositor and the Administrative Trustees, acting
          singly or together, (and, in the case of (iii) and (v) below, Robert
          J. Reger, Jr., as authorized representative of the Trust) shall have
          the right and responsibility to assist the Trust with respect to, or
          effect on behalf of the Trust, the following (and any actions taken by
          the Depositor in furtherance of the following prior to the date of
          this Trust Agreement are hereby ratified and confirmed in all
          respects):

                    (i) to prepare for filing by the Trust with the Commission
               and to execute a registration statement on Form S-3 in relation
               to the Preferred Trust Securities, including any amendments
               thereto;

                    (ii) to determine the States in which to take appropriate
               action to qualify or register for sale all or part of the
               Preferred Trust Securities and to do any and all such acts, other
               than actions which must be taken by or on behalf of the Trust,
               and advise the Trustees of actions they must take on behalf of
               the Trust, and prepare for execution and filing any documents to
               be executed and filed by the Trust or on behalf of the Trust, as
               the Depositor deems necessary or advisable in order to comply
               with the applicable laws of any such States;

                    (iii) to execute and deliver on behalf of the Trust the
               Underwriting Agreement and such other agreements as may be

               thereof;

                    (iv) to select the investment banker or bankers to act as
               underwriters with respect to the offer and sale by the Trust of
               Preferred Trust Securities ("Offer") and negotiate the terms of
               an Underwriting Agreement and pricing agreement providing for the
               Offer; and

                    (v) to take any other actions necessary or desirable to
               carry out any of the foregoing activities.

               (d) Notwithstanding anything herein to the contrary, the
          Administrative Trustees are authorized and directed to conduct the
          affairs of the Trust and to operate the Trust so that the Trust will
          not be deemed to be an "investment company" required to be registered
          under the Investment Company Act or classified other than as a
          "grantor trust" for United States federal income tax purposes and not
          as an association taxable as a corporation and so that the Debentures
          will be treated as indebtedness of the Debenture Issuer for United
          States federal income tax purposes. In this connection, the Depositor
          and the Administrative Trustees are authorized to take any action, not
          inconsistent with applicable law, the certificate of trust filed with
          the Secretary of State of the State of Delaware with respect to the
          Trust (as amended or restated from time to time, the "Certificate of
          Trust") or this Trust Agreement, that each of the Depositor and the

                                       14
<PAGE>

          Administrative Trustees determines in its discretion to be necessary
          or desirable for such purposes, as long as such action does not
          materially adversely affect the interests of the Holders of the
          Preferred Trust Securities.

               SECTION 2.08. ASSETS OF TRUST. The assets of the Trust shall
consist of the Trust Property.

               SECTION 2.09. TITLE TO TRUST PROPERTY. Legal title to all Trust
Property shall be vested at all times in the Property Trustee (in its capacity
as such) and shall be held and administered by the Property Trustee for the
benefit of the Securityholders in accordance with this Trust Agreement.

                                  ARTICLE III.

                                 PAYMENT ACCOUNT

               SECTION 3.01. PAYMENT ACCOUNT.

               (a) On or prior to the Closing Date, the Property Trustee shall
          establish the Payment Account. The Property Trustee and the Paying
          Agent appointed by the Administrative Trustees shall have exclusive
          control and sole right of withdrawal with respect to the Payment
          Account for the purpose of making deposits in and withdrawals from the
          Payment Account in accordance with this Trust Agreement. All monies
          and other property deposited or held from time to time in the Payment
          Account shall be held by the Property Trustee in the Payment Account
          for the exclusive benefit of the Holders of Trust Securities and for
          distribution as herein provided, including (and subject to) any
          priority of payments provided for herein. The Property Trustee shall
          have no liability in any respect whatsoever in regards to any moneys
          or other property deposited in the Payment Account at an institution
          other than the Property Trustee.

               (b) The Property Trustee shall deposit in the Payment Account,
          promptly upon receipt, all payments of principal or interest on, and
          any other payments or proceeds with respect to, the Debentures.
          Amounts held in the Payment Account shall not be invested by the
          Property Trustee pending distribution thereof.

                                   ARTICLE IV.

                            DISTRIBUTIONS; REDEMPTION

               SECTION 4.01. DISTRIBUTIONS.

               (a) Distributions on the Trust Securities shall be cumulative,
          and will accumulate whether or not there are funds of the Trust
          available for the payment of Distributions. Distributions shall accrue
          from the Closing Date, and, except in the event that the Depositor
          exercises its right to extend the interest payment period for the
          Debentures pursuant to Section 311 of the Subordinated Indenture,
          shall be payable quarterly in arrears on March 31, June 30, September
          30, and December 31 of each year, commencing on March 31, 2000. If any

                                       15
<PAGE>

          date on which Distributions are otherwise payable on the Trust
          Securities is not a Business Day, then the payment of such
          Distribution 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) in each case, with the same force and effect as if
          made on such date (each date on which Distributions are payable in
          accordance with this Section 4.01(a) a "Distribution Date").

               (b) Distributions payable on the Trust Securities shall be fixed
          at a rate of 8.70% per annum of the Liquidation Amount of the Trust
          Securities. The amount of Distributions payable for any quarterly
          period shall be computed on the same basis as interest is calculated
          on the Debentures. If the interest payment period for the Debentures
          is extended pursuant to Section 311 of the Subordinated Indenture,
          then Distributions on the Trust Securities will be deferred for the
          period equal to the extension of the interest payment period for the
          Debentures and the rate per annum at which Distributions on the Trust
          Securities accumulate shall be increased by an amount such that the
          aggregate amount of Distributions that accumulate on all Trust
          Securities during any such extended interest payment period is equal
          to the aggregate amount of interest (including, to the extent
          permitted by law, interest payable on unpaid interest at the
          percentage rate per annum set forth above, compounded quarterly) that
          accrues during any such extended interest payment period on the
          Debentures. The amount of Distributions payable for any period shall
          include the Additional Amounts, if any.

               (c) Distributions on the Trust Securities shall be made and shall
          be deemed payable on each Distribution Date only to the extent that
          the Trust has funds available in the Payment Account for the payment
          of such Distributions.

               (d) Distributions on the Trust Securities with respect to a
          Distribution Date shall be payable to the Holders thereof as they
          appear on the Securities Register for the Trust Securities on the
          relevant record date, which shall be one Business Day prior to the
          relevant Distribution Date, if Trust Securities are in book-entry only
          form, and 15 days prior to the relevant Distribution Date if Trust
          Securities are not in book-entry only form.

               SECTION 4.02. REDEMPTION. (a) On each Debenture Redemption Date
and at the maturity date ("Maturity Date") for the Debentures (as defined in the
Subordinated Indenture), the Property Trustee will be required to redeem a Like
Amount of Trust Securities at the Redemption Price plus accumulated and unpaid
Distributions to the Redemption Date or Maturity Date, as the case may be.

               (b) Notice of redemption shall be given by the Property Trustee
          by first-class mail, postage prepaid, mailed not less than 30 nor more
          than 60 days prior to the Redemption Date to each Holder of Trust
          Securities to be redeemed, at such Holder's address appearing in the
          Security Register. All notices of redemption or liquidation shall
          state:

                    (i) the Redemption Date;

                                       16
<PAGE>

                    (ii) the Redemption Price and the amount of accumulated and
               unpaid Distributions to be paid on the Redemption Date;

                    (iii) the CUSIP number;

                    (iv) if less than all the Outstanding Trust Securities are
               to be redeemed, the identification and the total Liquidation
               Amount of the particular Trust Securities to be redeemed; and

                    (v) that on the Redemption Date the Redemption Price plus
               accumulated and unpaid Distributions to the Redemption Date will
               become due and payable upon each such Trust Security to be
               redeemed and that Distributions thereon will cease to accrue on
               and after said date.

                  (c) The Trust Securities redeemed on each Redemption Date
         shall be redeemed at the Redemption Price plus accumulated and unpaid
         Distributions to the Redemption Date with the proceeds from the
         contemporaneous redemption of Debentures. Redemptions of the Trust
         Securities shall be made and the Redemption Price plus accumulated and
         unpaid Distributions to the Redemption Date shall be deemed payable on
         each Redemption Date only to the extent that the Trust has funds
         immediately available in the Payment Account for such payment.

                  (d) If the Property Trustee gives a notice of redemption in
         respect of any Preferred Trust Securities, then, by 12:00 noon, New
         York time, on the Redemption Date, subject to Section 4.02(c), the
         Property Trustee shall irrevocably deposit with the Paying Agent funds
         sufficient to pay the applicable Redemption Price plus accumulated and
         unpaid Distributions to the Redemption Date and will give the Paying
         Agent irrevocable instructions and authority to pay the Redemption
         Price plus accumulated and unpaid Distributions to the Redemption Date
         to the Holders thereof upon surrender of their Preferred Trust
         Securities Certificates and Common Trust Securities Certificates.
         Notwithstanding the foregoing, Distributions on the Trust Securities
         with respect to Distribution Dates occurring on or prior to the
         Redemption Date for any Trust Securities called for redemption shall be
         payable to the Holders of such Trust Securities as they appear on the
         Securities Register for the Trust Securities on the relevant record
         dates for the related Distribution Dates. If notice of redemption shall
         have been given and funds deposited as required, then on the Redemption
         Date, all rights of Securityholders holding Trust Securities so called
         for redemption will cease, except the right of such Securityholders to
         receive the Redemption Price plus accumulated and unpaid Distributions
         to the Redemption Date thereof, but without interest thereon, and such
         Trust Securities will cease to be Outstanding. In the event that any
         Redemption Date is not a Business Day, then payment of the Redemption
         Price payable on such date plus accumulated and unpaid Distributions to
         such Redemption 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) with the same force and effect as if made on such date.
         In the event that payment of the Redemption Price plus accumulated and
         unpaid Distributions in respect of any Trust Securities called for
         redemption is improperly withheld or refused and not paid either by the
         Trust or by the Depositor pursuant to the Guarantee, Distributions on

                                       17
<PAGE>

         such Trust Securities will continue to accrue, at the then applicable
         rate, from the Redemption Date originally established by the Trust for
         such Trust Securities to the date such Redemption Price plus
         accumulated and unpaid Distributions is actually paid, in which case
         the actual payment date will be deemed the date fixed for redemption
         for purposes of calculating the Redemption Price plus accumulated and
         unpaid Distributions to such date.

                  (e) Payment of the Redemption Price on the Trust Securities
         shall be made to the Holders thereof as they appear on the Securities
         Register for the Trust Securities on the Redemption Date.

                  (f) If less than all the Outstanding Trust Securities are to
         be redeemed on a Redemption Date, then the aggregate Liquidation Amount
         of Trust Securities to be redeemed shall be allocated to the Common
         Trust Securities and to the Preferred Trust Securities in the
         proportion that the aggregate Liquidation Amount of each is to the
         aggregate Liquidation Amount of all outstanding Trust Securities. The
         particular Preferred Trust Securities to be redeemed shall be selected
         not more than 60 days prior to the Redemption Date by the Property
         Trustee from the Outstanding Preferred Trust Securities not previously
         called for redemption, by such method as the Property Trustee shall
         deem fair and appropriate and which may provide for the selection for
         redemption of portions (equal to $25 or integral multiples thereof) of
         the Liquidation Amount of Preferred Trust Securities of a denomination
         larger than $25. The Property Trustee shall promptly notify the
         Transfer Agent and Registrar in writing of the Preferred Trust
         Securities selected for redemption and, in the case of any Preferred
         Trust Securities selected for partial redemption, the Liquidation
         Amount thereof to be redeemed. For all purposes of this Trust
         Agreement, unless the context otherwise requires, all provisions
         relating to the redemption of Preferred Trust Securities shall relate,
         in the case of any Preferred Trust Securities redeemed or to be
         redeemed only in part, to the portion of the Liquidation Amount of
         Preferred Trust Securities which has been or is to be redeemed.

               SECTION 4.03. SUBORDINATION OF COMMON TRUST SECURITIES. (a)
Payment of Distributions (including Additional Amounts, if applicable) on, and
the Redemption Price plus accumulated and unpaid Distributions of, the Trust
Securities, as applicable, shall be made pro rata based on the Liquidation
Amount of the Trust Securities; provided, however, that if on any Distribution
Date or Redemption Date an Event of Default shall have occurred and be
continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price plus accumulated and unpaid Distributions
of, any Common Trust Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Trust Securities, shall
be made unless payment in full in cash of all accumulated and unpaid
Distributions (including Additional Amounts, if applicable) on all Outstanding
Preferred Trust Securities for all distribution periods terminating on or prior
thereto, or in the case of payment of the Redemption Price plus accumulated and
unpaid Distributions the full amount of such Redemption Price plus accumulated
and unpaid Distributions on all Outstanding Preferred Trust Securities, shall
have been made or provided for, and all funds immediately available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or Redemption
Price plus accumulated and unpaid Distributions of, Preferred Trust Securities
then due and payable.

                  (b) In the case of the occurrence of any Event of Default
         resulting from a Debenture Event of Default, the Holder of Common Trust
         Securities will be deemed to have waived any such Event of Default
         under this Trust Agreement until the effect of all such Events of
         Default with respect to the Preferred Trust Securities have been cured,
         waived or otherwise eliminated. Until all such Events of Default under
         this Trust Agreement with respect to the Preferred Trust Securities
         have been so cured, waived or otherwise eliminated, the Property
         Trustee shall act solely on behalf of the Holders of the Preferred
         Trust Securities and not the Holder of the Common Trust Securities, and
         only the Holders of the Preferred Trust Securities will have the right
         to direct the Property Trustee to act on their behalf.

               SECTION 4.04. PAYMENT PROCEDURES. Payments in respect of the
aPreferred Trust Securities shall be made by check mailed to the address of the
Person entitled thereto as such address shall appear on the Securities Register
or, if the Preferred Trust Securities are held by a Securities Depository, such
Distributions shall be made to the Securities Depository, which shall credit the
relevant Persons' accounts at such Securities Depository on the applicable
Distribution Dates. Payments in respect of the Common Trust Securities shall be
made in such manner as shall be mutually agreed between the Administrative
Trustees and the Holder of the Common Trust Securities.

               SECTION 4.05. TAX RETURNS AND REPORTS. The Administrative
Trustees shall prepare (or cause to be prepared), at the Depositor's expense and
direction, and file all United States federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared or filed) the Internal Revenue Service Form 1041 (or
any successor form) required to be filed in respect of the Trust in each taxable
year of the Trust and (b) prepare and furnish (or cause to be prepared and
furnished) to each Securityholder the related Internal Revenue Service Form
1099, or any successor form or the information required to be provided on such
form. The Administrative Trustees shall provide the Depositor and the Property
Trustee with a copy of all such returns, reports and schedules promptly after
such filing or furnishing. The Trustees shall comply with United States federal
withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

               SECTION 4.06. PAYMENTS UNDER INDENTURE. Any amount payable
hereunder to any Holder of Preferred Trust Securities shall be reduced by the
amount of any corresponding payment such Holder has directly received pursuant
to Section 808 of the Subordinated Indenture. Notwithstanding the provisions
hereunder to the contrary, Securityholders acknowledge that any Holder of
Preferred Trust Securities that receives payment under Section 808 of the
Subordinated Indenture may receive amounts greater than the amount such Holder
may be entitled to receive pursuant to the other provisions of this Trust
Agreement.

Transfer Agent and Registrar or its agent, shall be validly issued and entitled
to the benefits of this Trust Agreement, notwithstanding that such individuals
or any of them shall have ceased to be so authorized prior to the delivery of
such Trust Securities Certificates or did not hold such offices at the date of
delivery of such Trust Securities Certificates. A transferee of a Trust

corporate action by the Depositor, in authorized denominations. The Depositor
agrees to indemnify, defend and hold The Bank of New York harmless against any
and all costs and liabilities incurred without negligence arising out of or in
connection with any such countersigning by it.

Section 5.08, the Administrative Trustees, or any one of them, shall execute on
behalf of the Trust by manual or facsimile signature and, if executed on behalf
of the Trust by facsimile signature, cause the Transfer Agent and Registrar or
its agent to countersign and deliver, in the name of the designated transferee
or transferees, one or more new Preferred Trust Securities Certificates in
authorized denominations of a like aggregate Liquidation Amount. At the option
of a Holder, Preferred Trust Securities Certificates may be exchanged for other
Preferred Trust Securities Certificates in authorized denominations of the same
class and of a like aggregate Liquidation Amount upon surrender of the Preferred
Trust Securities Certificates to be exchanged at the office or agency maintained
pursuant to Section 5.08.

               Every Preferred Trust Securities Certificate presented or
surrendered for registration of transfer or exchange shall be accompanied by a
written instrument of transfer in form satisfactory to the Administrative
Trustees and the Transfer Agent and Registrar duly executed by the Holder or
such Holder's attorney duly authorized in writing. Each Preferred Trust
Securities Certificate surrendered for registration of transfer or exchange
shall be canceled and subsequently disposed of by the Administrative Trustees in
accordance with customary practice. The Trust shall not be required to (i)
issue, register the transfer of, or exchange any Preferred Trust Securities
during a period beginning at the opening of business 15 calendar days before the
day of mailing of a notice of redemption of any Preferred Trust Securities
called for redemption and ending at the close of business on the day of such
mailing or (ii) register the transfer of or exchange any Preferred Trust
Securities so selected for redemption, in whole or in part, except the
unredeemed portion of any such Preferred Trust Securities being redeemed in
part.

               No service charge shall be made for any registration of transfer
or exchange of Preferred Trust Securities Certificates, but the Transfer Agent
and Registrar may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer or
exchange of Preferred Trust Securities Certificates.

               SECTION 5.05. MUTILATED, DESTROYED, LOST OR STOLEN TRUST
SECURITIES CERTIFICATES. If (a) any mutilated Trust Securities Certificate shall
be surrendered to the Transfer Agent and Registrar, or if the Transfer Agent and
Registrar shall receive evidence to its satisfaction of the destruction, loss or
theft of any Trust Securities Certificate and (b) there shall be delivered to
the Transfer Agent and Registrar and the Administrative Trustees such security
or indemnity as may be required by them to save each of them and the Depositor
harmless, then in the absence of notice that such Trust Securities Certificate
shall have been acquired by a bona fide purchaser, the Administrative Trustees,
or any one of them, on behalf of the Trust shall execute by manual or facsimile
signature and, if execution on behalf of the Trust is by facsimile signature,
countersigned by a Transfer Agent and Registrar or its agent; and the
Administrative Trustees, or any one of them, and, if executed on behalf of the
Trust by facsimile signature, countersigned by the Transfer Agent and Registrar
or its agent shall make available for delivery, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a
new Trust Securities Certificate of like class, tenor and denomination. In
connection with the issuance of any new Trust Securities Certificate under this
Section, the Administrative Trustees or the Transfer Agent and Registrar may
require the payment of a sum sufficient to cover any tax or other governmental

                                       21
<PAGE>

charge that may be imposed in connection therewith. Any duplicate Trust
Securities Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

               SECTION 5.06. PERSONS DEEMED SECURITYHOLDERS. Prior to due
presentation of a Trust Securities Certificate for registration of transfer, the
Trustees and the Transfer Agent and Registrar, and any agent of the Trustee and
the Transfer Agent and Registrar, shall be entitled to treat the Person in whose
name any Trust Securities Certificate shall be registered in the Securities
Register as the owner of such Trust Securities Certificate for the purpose of
receiving Distributions and for all other purposes whatsoever, and neither the
Trustees nor the Transfer Agent and Registrar shall be bound by any notice to
the contrary.

               SECTION 5.07. ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND
ADDRESSES. The Administrative Trustees shall furnish or cause to be furnished
(x) to the Depositor, within 15 days after receipt by any Administrative Trustee
of a request therefor from the Depositor in writing and (y) to the Property
Trustee, promptly after receipt by any Administrative Trustee of a request
therefor from the Property Trustee in writing in order to enable the Property
Trustee to discharge its obligations under this Trust Agreement, a list, in such
form as the Depositor or the Property Trustee may reasonably require, of the
names and addresses of the Securityholders as of a recent date. If Holders of
Trust Securities Certificates evidencing ownership at such time and for the
previous six months not less than 25% of the Outstanding aggregate Liquidation
Amount apply in writing to any Administrative Trustee, and such application
states that the applicants desire to communicate with other Securityholders with
respect to their rights under this Trust Agreement or under the Trust Securities
Certificates and such application is accompanied by a copy of the communication
that such applicants propose to transmit, then the Administrative Trustees
shall, within five Business Days after the receipt of such application, afford
such applicants access during normal business hours to the current list of
Securityholders. Each Holder, by receiving and holding a Trust Securities
Certificate, shall be deemed to have agreed not to hold either the Depositor or
any Trustees accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

               SECTION 5.08. MAINTENANCE OF OFFICE OR AGENCY. The Depositor
shall or shall cause the Transfer Agent and Registrar to maintain in the Borough
of Manhattan, The City of New York, an office or offices or agency or agencies
where Preferred Trust Securities Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Depositor, the Trust or the Transfer Agent and Registrar in respect of the
Trust Securities and the Trust Agreement may be served. The Depositor initially
designates Midwest Clearing Corporation, 40 Broad Street, New York, New York
10004 as its principal office for such purposes. The Depositor shall or shall
cause the Transfer Agent and Registrar to give prompt written notice to the
Depositor, the Property Trustee and to the Securityholders of any change in the
location of the Securities Register or any such office or agency. If at any time
the Depositor shall fail to maintain such office or agency or shall fail to
furnish the Property Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Property Trustee, and the Depositor hereby appoints the Property
Trustee its agent and the agent of the Trust to receive all such presentations,
surrenders, notices and demands.

                                       22

               SECTION 5.09. APPOINTMENT OF PAYING AGENT. The Paying Agent shall
make distributions to Securityholders from the Payment Account and shall report
the amounts of such distributions to the Administrative Trustees and the
Property Trustee. Any Paying Agent shall have the revocable power to withdraw
funds from the Payment Account for the purpose of making the Distributions
referred to above. The Property Trustee shall be entitled to rely upon a
certificate of the Paying Agent stating in effect the amount of such funds so to
be withdrawn and that same are to be applied by the Paying Agent in accordance
with this Section 5.09. The Administrative Trustees or any one of them may
revoke such power and remove the Paying Agent if the Administrative Trustee or
any one of them determines in its sole discretion that the Paying Agent shall
have failed to perform its obligations under this Trust Agreement in any
material respect. The Bank of New York is hereby appointed as the initial Paying
Agent, and it may choose any co-paying agent that is acceptable to the
Administrative Trustees and the Depositor. The Paying Agent shall be permitted
to resign upon 30 days' written notice to the Administrative Trustees and the
Depositor. In the event of the removal or resignation of The Bank of New York as
Paying Agent, the Administrative Trustees shall appoint a successor that is
reasonably acceptable to the Property Trustee and the Depositor to act as Paying
Agent (which shall be a bank, trust company or an Affiliate of the Depositor).
The Administrative Trustees shall cause such successor Paying Agent or any
additional Paying Agent appointed by the Administrative Trustees to execute and
deliver to the Trustees an instrument in which such successor Paying Agent or
additional Paying Agent shall agree with the Trustees that as Paying Agent, such
successor Paying Agent or additional Paying Agent will hold all sums, if any,
held by it for payment to the Securityholders in trust for the benefit of the
Securityholders entitled thereto until such sums shall be paid to such
Securityholders. The Paying Agent shall return all unclaimed funds to the
Property Trustee and upon resignation or removal of a Paying Agent such Paying
Agent shall also return all funds in its possession to the Property Trustee. The
provisions of Sections 8.01, 8.03 and 8.06 shall apply to the Paying Agent
appointed hereunder, and the Paying Agent shall be bound by the requirements
with respect to paying agents of securities issued pursuant to the Trust
Indenture Act. Any reference in this Trust Agreement to the Paying Agent shall
include any co-paying agent unless the context requires otherwise.

               SECTION 5.10. OWNERSHIP OF COMMON TRUST SECURITIES BY DEPOSITOR.
On the Closing Date, the Depositor shall acquire, and thereafter retain,
beneficial and record ownership of the Common Trust Securities. Except in
connection with a transaction involving the Depositor that would be permitted
under Article Eleven of the Subordinated Indenture, any attempted transfer of
the Common Trust Securities shall be void. The Administrative Trustees shall
cause each Common Trust Securities Certificate issued to the Depositor to
contain a legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS
PROVIDED IN THE TRUST AGREEMENT". Common Trust Securities Certificates
representing the Common Trust Securities shall be issued to the Depositor in the
form of a typewritten or definitive Common Trust Securities Certificate.

               SECTION 5.11. DEFINITIVE PREFERRED TRUST SECURITIES CERTIFICATES.
Upon initial issuance of the Preferred Trust Securities, the Definitive
Preferred Trust Securities Certificates shall be typewritten, printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Administrative Trustees, as evidenced by the execution thereof
by the Administrative Trustees, or any one of them. The Administrative Trustees,

                                       23
<PAGE>

or any one of them, shall execute on behalf of the Trust by manual or facsimile
signature, and, if executed by facsimile on behalf of the Trust, countersigned
by the Transfer Agent and Registrar or its agent, the Definitive Preferred Trust
Securities Certificates initially in accordance with the instructions of the
Depositor. Neither the Transfer Agent and Registrar nor any of the
Administrative Trustees shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions.

               SECTION 5.12. BOOK-ENTRY SYSTEM. Some or all of the Preferred
Trust Securities may be registered in the name of a securities depository
("Securities Depository") or a nominee therefor, and held in the custody of the
Securities Depository or a custodian thereof. In such event, a single
certificate will be issued and delivered to the Securities Depository for such
Preferred Trust Securities, in which case the Owners of such Preferred Trust
Securities will not receive physical delivery of certificates for Preferred
Trust Securities. Except as provided herein, all transfers of beneficial
ownership interests in such Preferred Trust Securities will be made by
book-entry only, and no investor or other party purchasing, selling or otherwise
transferring beneficial ownership of the Preferred Trust Securities will
receive, hold or deliver any certificate for Preferred Trust Securities. The
Depositor, the Trustees and the Paying Agent will recognize the Securities
Depository or its nominee as the Holder of Preferred Trust Securities for all
purposes, including notices and voting.

               The Administrative Trustees, at the direction and expense of the
Depositor, may from time to time appoint a Securities Depository or a successor
thereto and enter into a letter of representations or other agreement with such
Securities Depository to establish procedures with respect to the Preferred
Trust Securities. Any Securities Depository shall be a Clearing Agency.

               The Depositor and the Trustees covenant and agree to meet the
requirements of a Securities Depository for the Preferred Trust Securities with
respect to required notices and other provisions of the letter of
representations or agreement executed with respect to such Preferred Trust
Securities.

               Whenever the beneficial ownership of any Preferred Trust
Securities is determined through the books of a Securities Depository, the
requirements in this Trust Agreement of holding, delivering or transferring such
Preferred Trust Securities shall be deemed modified with respect to such
Preferred Trust Securities to meet the requirements of the Securities Depository
with respect to actions of the Trustees, the Depositor and the Paying Agent. Any
provisions hereof permitting or requiring delivery of such Preferred Trust
Securities shall, while such Preferred Trust Securities are in a book-entry
system, be satisfied by the notation on the books of the Securities Depository
in accordance with applicable state law.

               SECTION 5.13. RIGHTS OF SECURITYHOLDERS. The legal title to the
Trust Property is vested exclusively in the Property Trustee (in its capacity as
such) in accordance with Section 2.09, and the Securityholders shall not have
any right or title therein other than an undivided beneficial interest in the
assets of the Trust conferred by their Trust Securities and they shall have no
right to call for any partition or division of property, profits or rights of
the Trust except as described below. The Trust Securities shall be personal
property giving only the rights specifically set forth therein and in this Trust
Agreement. The Preferred Trust Securities shall have no preemptive or similar
rights and when issued and delivered to Securityholders against payment of the

                                       24
<PAGE>

purchase price therefor will be fully paid and nonassessable undivided
beneficial interests in the assets of the Trust.

               SECTION 5.14. CANCELLATION BY TRANSFER AGENT AND REGISTRAR. All
Trust Securities Certificates surrendered for payment, redemption, registration
of transfer or exchange shall, if surrendered to any Person other than the
Transfer Agent and Registrar, be delivered to the Transfer Agent and Registrar
and, if not theretofore cancelled, shall be promptly cancelled by the Transfer
Agent and Registrar. No Trust Securities Certificates shall be issued in lieu of
or in exchange for any Trust Securities Certificates cancelled as provided in
this Section, except as expressly permitted by this Trust Agreement. All
cancelled Trust Securities Certificates held by the Transfer Agent and Registrar
shall be disposed of in accordance with customary practices.

                                   ARTICLE VI.

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

               SECTION 6.01. LIMITATIONS ON VOTING RIGHTS. (a) Except as
provided in this Section 6.01, in Section 10.03 and as otherwise required by
law, no Holder of Preferred Trust Securities shall have any right to vote or in
any manner otherwise control the administration, operation and management of the
Trust or the obligations of the parties hereto, nor shall anything herein set
forth, or contained in the terms of the Trust Securities Certificates, be
construed so as to constitute the Securityholders from time to time as partners
or members of an association. If the Property Trustee fails to enforce its
rights under the Debentures or this Trust Agreement, a Holder of Preferred Trust
Securities may institute a legal proceeding directly against the Depositor to
enforce the Property Trustee's rights under the Debentures or this Trust
Agreement, to the fullest extent permitted by law, without first instituting any
legal proceeding against the Property Trustee or any other Person.
Notwithstanding the foregoing, a Holder of Preferred Trust Securities may
directly institute a proceeding for enforcement of payment to such Holder of
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation preference amount of the Preferred Trust Securities of
such Holder on or after the due dates specified in the Debentures.

               (b) So long as any Debentures are held by the Property Trustee,
          the Trustees shall not (i) direct the time, method and place of
          conducting any proceeding for any remedy available to the Debenture
          Trustee, or executing any trust or power conferred on the Debenture
          Trustee with respect to such Debentures, (ii) waive any past default
          which is waivable under Section 813 of the Subordinated Indenture,
          (iii) exercise any right to rescind or annul a declaration that the
          principal of all the Debentures shall be due and payable or (iv)
          consent to any amendment, modification or termination of the
          Subordinated Indenture or the Debentures, where such consent shall be
          required, without, in each case, obtaining the prior approval of the
          Holders of at least 66 2/3% of the aggregate Liquidation Amount of the
          Outstanding Preferred Trust Securities; provided, however, that where
          a consent under the Subordinated Indenture would require the consent
          of each Holder of Debentures affected thereby, no such consent shall
          be given by any Trustee without the prior written consent of each
          Holder of Preferred Trust Securities. The Trustees shall not revoke
          any action previously authorized or approved by a vote of the
          Preferred Trust Securities, except pursuant to a subsequent vote of

                                       25
<PAGE>

          the Preferred Trust Securities. The Property Trustee shall notify all
          Holders of the Preferred Trust Securities of any notice of default
          received from the Debenture Trustee with respect to the Debentures. In
          addition to obtaining the foregoing approvals of the Holders of the
          Preferred Trust Securities, prior to taking any of the foregoing
          actions, the Property Trustee shall, at the expense of the Depositor,
          obtain an Opinion of Counsel experienced in such matters to the effect
          that the Trust will be classified as a "grantor trust" and not as an
          association taxable as a corporation for United States federal income
          tax purposes on account of such action.

               (c) If any proposed amendment to the Trust Agreement provides
          for, or the Trustees otherwise propose to effect, (i) any action that
          would materially adversely affect the powers, preferences or special
          rights of the Preferred Trust Securities, whether by way of amendment
          to the Trust Agreement or otherwise, or (ii) the dissolution,
          winding-up or termination of the Trust, other than pursuant to the
          terms of this Trust Agreement, then the Holders of Outstanding
          Preferred Trust Securities as a class will be entitled to vote on such
          amendment or proposal and such amendment or proposal shall not be
          effective except with the approval of the Holders of at least 66 2/3%
          in aggregate Liquidation Amount of the Outstanding Preferred Trust
          Securities.

               SECTION 6.02. NOTICE OF MEETINGS. Notice of all meetings of the
Holders of Preferred Trust Securities, stating the time, place and purpose of
the meeting, shall be given by the Administrative Trustees pursuant to Section
10.08 to each Holder of a Preferred Trust Security, at his registered address,
at least 15 days and not more than 90 days before the meeting. At any such
meeting, any business properly before the meeting may be so considered whether
or not stated in the notice of the meeting. Any adjourned meeting may be held as
adjourned without further notice.

               SECTION 6.03. MEETINGS OF HOLDERS OF PREFERRED TRUST SECURITIES.
No annual meeting of Securityholders is required to be held. The Administrative
Trustees, however, shall call a meeting of Securityholders to vote on any matter
upon the written request of the Holders of 25% of the then Outstanding Preferred
Trust Securities (based upon their aggregate Liquidation Amount) and may, at any
time in their discretion, call a meeting of Holders of Preferred Trust
Securities to vote on any matters as to which the Holders of Preferred Trust
Securities are entitled to vote.

               Holders of 50% of the then Outstanding Preferred Trust Securities
(based upon their aggregate Liquidation Amount), present in person or by proxy,
shall constitute a quorum at any meeting of Securityholders.

               If a quorum is present at a meeting, an affirmative vote by the
Holders of Preferred Trust Securities present, in person or by proxy, holding
more than the lesser of (x) 66 2/3% of the then Outstanding Preferred Trust
Securities (based upon their aggregate Liquidation Amount) held by the Holders
of then Outstanding Preferred Trust Securities present, either in person or by
proxy, at such meeting and (y) 50% of the Outstanding Preferred Trust Securities
(based upon their aggregate Liquidation Amount) shall constitute the action of
the Securityholders, unless this Trust Agreement requires a greater number of
affirmative votes.

                                       26
<PAGE>

               SECTION 6.04. VOTING RIGHTS. Securityholders shall be entitled to
one vote for each $25 of Liquidation Amount represented by their Trust
Securities in respect of any matter as to which such Securityholders are
entitled to vote.

               SECTION 6.05. PROXIES, ETC. At any meeting of Securityholders,
any Securityholder entitled to vote thereat may vote by proxy, provided that no
proxy shall be voted at any meeting unless it shall have been placed on file
with the Administrative Trustees, or with such other officer or agent of the
Trust as the Administrative Trustees may direct, for verification prior to the
time at which such vote shall be taken. Only Securityholders of record shall be
entitled to vote. When Trust Securities are held jointly by several Persons, any
one of them may vote at any meeting in person or by proxy in respect of such
Trust Securities, but if more than one of them shall be present at such meeting
in person or by proxy, and such joint owners or their proxies so present
disagree as to any vote to be cast, such vote shall not be received in respect
of such Trust Securities. A proxy purporting to be executed by or on behalf of a
Securityholder shall be deemed valid unless challenged at or prior to its
exercise, or, if earlier, until eleven months after it is sent and the burden of
proving invalidity shall rest on the challenger.

               SECTION 6.06. SECURITYHOLDER ACTION BY WRITTEN CONSENT. Any
action which may be taken by Securityholders at a meeting may be taken without a
meeting and without notice if Securityholders holding a majority of all
Outstanding Trust Securities entitled to vote in respect of such action (or such
larger proportion thereof as shall be required by any express provision of this
Trust Agreement) shall consent to the action in writing (based upon their
aggregate Liquidation Amount).

               SECTION 6.07. RECORD DATE FOR VOTING AND OTHER PURPOSES. For the
purposes of determining the Securityholders who are entitled to notice of and to
vote at any meeting or to vote by written consent, or to participate in any
Distribution on the Trust Securities in respect of which a record date is not
otherwise provided for in this Trust Agreement, or for the purpose of any other
action, the Administrative Trustees may from time to time fix a date, not more
than 90 days prior to the date of any meeting of Securityholders or the payment
of Distribution or other action including action to be taken by written consent,
as the case may be, as a record date for the determination of the identity of
the Securityholders of record for such purposes.

               SECTION 6.08. ACTS OF SECURITYHOLDERS. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Trust Agreement to be given, made or taken by Securityholders
may be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Securityholders in person or by an agent duly
appointed in writing; and, except as otherwise expressly provided herein, such
action shall become effective when such instrument or instruments are delivered
to the Administrative Trustees. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Securityholders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Trust Agreement and (subject to Section
8.01) conclusive in favor of the Trustees, if made in the manner provided in
this Section.

                                       27
<PAGE>

               The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgements of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which any Trustee deems sufficient.

               The ownership of Preferred Trust Securities shall be proved by
the Securities Register.

               Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Securityholder of any Trust Security shall bind every
future Securityholder of the same Trust Security and the Securityholder of every
Trust Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

               Without limiting the foregoing, a Securityholder entitled
hereunder to take any action hereunder with regard to any particular Trust
Security may do so with regard to all or any part of the Liquidation Amount of
such Trust Security or by one or more duly appointed agents each of which may do
so pursuant to such appointment with regard to all or any part of such
Liquidation Amount.

               If any dispute shall arise between or among the Securityholders
and the Administrative Trustees with respect to the authenticity, validity or
binding nature of any request, demand, authorization, direction, consent, waiver
or other Act of such Securityholder or Trustee under this Article VI, then the
determination of such matter by the Property Trustee shall be conclusive with
respect to such matter.

               SECTION 6.09. INSPECTION OF RECORDS. Subject to Section 5.07
concerning access to the list of Securityholders, upon reasonable notice to the
Administrative Trustees and the Property Trustee, the other records of the Trust
shall be open to inspection by Securityholders during normal business hours for
any purpose reasonably related to such Securityholder's interest as a
Securityholder.

                                  ARTICLE VII.

                 REPRESENTATIONS AND WARRANTIES OF THE PROPERTY
                        TRUSTEE AND THE DELAWARE TRUSTEE

               SECTION 7.01. PROPERTY TRUSTEE. The Property Trustee hereby
represents and warrants for the benefit of the Depositor and the Securityholders
that:

               (a) the Property Trustee is a banking corporation or trust
          company duly organized, validly existing and in good standing under
          the laws of the State of New York;

                                       28
<PAGE>

               (b) the Property Trustee has full corporate power, authority and
          legal right to execute, deliver and perform its obligations under this
          Trust Agreement and has taken all necessary action to authorize the
          execution, delivery and performance by it of this Trust Agreement;

               (c) this Trust Agreement has been duly authorized, executed and
          delivered by the Property Trustee and constitutes the valid and
          legally binding agreement of the Property Trustee enforceable against
          it in accordance with its terms, subject to bankruptcy, insolvency,
          fraudulent transfer, reorganization, moratorium and similar laws of
          general applicability relating to or affecting creditors' rights and
          to general equity principles;

               (d) the execution, delivery and performance by the Property
          Trustee of this Trust Agreement will not violate, conflict with or
          constitute a breach of the Property Trustee's charter or by-laws; and

               (e) the execution, delivery and performance by the Property
          Trustee of this Trust Agreement does not require the consent or
          approval of, the giving of notice to, or the registration with any
          Federal or New York banking authority.

               SECTION 7.02. DELAWARE TRUSTEE. The Delaware Trustee represents
and warrants for the benefit of the Depositor and the Securityholders that:

               (a) the Delaware Trustee is a banking corporation or trust

                                  ARTICLE VIII.

                                  THE TRUSTEES

               SECTION 8.01. CERTAIN DUTIES AND RESPONSIBILITIES.

               (a) The duties and responsibilities of the Trustees shall be
          restricted to those set forth in the express provisions of this Trust
          Agreement and, in the case of the Property Trustee, as provided in the
          Trust Indenture Act, and no implied covenants or obligations shall be
          read into this Trust Agreement against any of the Trustees. For
          purposes of Sections 315(a) and 315(c) of the Trust Indenture act, the
          term "default" is hereby defined as an Event of Default which has
          occurred and is continuing. Notwithstanding the foregoing, no
          provision of this Trust Agreement shall require any of the Trustees to
          expend or risk its own funds or otherwise incur any financial
          liability in the performance of any of its duties hereunder, or in the
          exercise of any of its rights or powers, if it shall have reasonable
          grounds for believing that repayment of such funds or adequate
          indemnity against such risk or liability is not reasonably assured to
          it. Notwithstanding anything contained in this Trust Agreement to the
          contrary, the duties and responsibilities of the Property Trustee
          under this Trust Agreement shall be subject to the protections,
          exculpations and limitations on liability afforded to the Property
          Trustee under this Trust Agreement, the Trust Indenture Act, the
          Delaware Business Trust Act and, to the extent applicable, Rule 3a-7
          under the Investment Company Act or any successor rule thereunder.
          Whether or not therein expressly so provided, every provision of this
          Trust Agreement relating to the conduct or affecting the liability of
          or affording protection to the Trustees shall be subject to the
          provisions of this Section 8.01.

               (b) All payments made by the Property Trustee or a Paying Agent
          in respect of the Trust Securities shall be made only from the income
          and proceeds from the Trust Property and only to the extent that there
          shall be sufficient income or proceeds from the Trust Property to
          enable the Property Trustee or Paying Agent to make payments in
          accordance with the terms hereof. Each Securityholder, by its
          acceptance of a Trust Security, agrees that it will look solely to the
          income and proceeds from the Trust Property to the extent available
          for distribution to it as herein provided and that the Trustees are
          not personally liable to it for any amount distributable in respect of
          any Trust Security or for any other liability in respect of any Trust
          Security. This Section 8.01(b) does not limit the liability of the
          Trustees expressly set forth elsewhere in this Trust Agreement or, in
          the case of the Property Trustee, in the Trust Indenture Act.

               (c) All duties and responsibilities of the Property Trustee
          contained in this Trust Agreement are subject to the following:

                    (i) the Property Trustee's sole duty with respect to the
               custody, safe keeping and physical preservation of the Trust
               Property shall be to deal with such property in a similar manner
               as the Property Trustee deals with similar property for its own
               account, subject to the protections, exculpations and limitations
               on liability afforded to the Property Trustee under this Trust
               Agreement, the Trust Indenture Act, the Delaware Business Trust

                                       30
<PAGE>

               Act and, to the extent applicable, Rule 3a-7 under the Investment
               Company Act or any successor rule thereunder;

                    (ii) the Property Trustee shall have no duty or liability
               for or with respect to the value, genuineness, existence or
               sufficiency of the Trust Property or the payment of any taxes or
               assessments levied thereon or in connection therewith;

                    (iii) the Property Trustee shall not be liable for any
               interest on any money received by it except as it may otherwise
               agree with the Depositor. Money held by the Property Trustee need
               not be segregated from other funds held by it except in relation
               to the Payment Account established by the Property Trustee
               pursuant to this Trust Agreement and except to the extent
               otherwise required by law; and

                    (iv) the Property Trustee shall not be responsible for
               monitoring the compliance by the Administrative Trustees or the
               Depositor with their respective duties under this Trust
               Agreement, nor shall the Property Trustee be liable for the
               default or misconduct of the Administrative Trustees or the
               Depositor.

               SECTION 8.02. NOTICE OF DEFAULTS. (a) Within ninety (90) days
after the occurrence of any default known to the Property Trustee, the Property
Trustee shall transmit, in the manner and to the extent provided in Section
10.08, notice of such default to the Securityholders and the Depositor, unless
such default shall have been cured or waived. For the purpose of this Section,
the term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default.

                  (b) Within five Business Days after receipt of notice of the
         Debenture Issuer's exercise of its right to defer the payment of
         interest on the Debentures pursuant to the Subordinated Indenture, an
         Administrative Trustee shall transmit, in the manner and to the extent
         provided in Section 10.08, notice of such exercise to the
         Securityholders and the Property Trustee.

               SECTION 8.03. CERTAIN RIGHTS OF PROPERTY TRUSTEE. Subject to the
provisions of Section 8.01 and except as provided by law:

                    (i) the Property Trustee may rely and shall be protected in
               acting or refraining from acting in good faith upon any
               resolution, Opinion of Counsel, certificate, written
               representation of a Holder or transferee, certificate of auditors
               or any other certificate, statement, instrument, opinion, report,
               notice, request, direction, consent, order, appraisal, bond,
               debenture, note, other evidence of indebtedness or other paper or
               document reasonably believed by it to be genuine and to have been
               signed or presented by the proper party or parties;

                    (ii) if (A) in performing its duties under this Trust
               Agreement the Property Trustee is required to decide between
               alternative courses of action or (B) in construing any of the
               provisions in this Trust Agreement the Property Trustee finds the

                                       31
<PAGE>

               same ambiguous or inconsistent with any other provisions
               contained herein or (C) the Property Trustee is unsure of the
               application of any provision of this Trust Agreement, then,
               except as to any matter as to which the Preferred Trust
               Securityholders are entitled to vote under the terms of this
               Trust Agreement, the Property Trustee shall deliver a notice to
               the Depositor requesting written instructions of the Depositor as
               to the course of action to be taken. The Property Trustee shall
               take such action, or refrain from taking such action, as the
               Property Trustee shall be instructed in writing to take, or to
               refrain from taking, by the Depositor; provided, however, that if
               the Property Trustee does not receive such instructions of the
               Depositor within ten Business Days after it has delivered such
               notice, or such reasonably shorter period of time set forth in
               such notice (which to the extent practicable shall not be less
               than two Business Days), it may, but shall be under no duty to,
               take or refrain from taking such action not inconsistent with
               this Trust Agreement as it shall deem advisable and in the best
               interests of the Securityholders, in which event the Property
               Trustee shall have no liability except for its own bad faith,
               negligence or willful misconduct;

                    (iii) whenever in the administration of this Trust Agreement
               the Property Trustee shall deem it desirable that a matter be
               proved or established prior to taking, suffering or omitting any
               action hereunder, the Property Trustee (unless other evidence be
               herein specifically prescribed) may, in the absence of bad faith
               on its part, request and rely upon an Officers' Certificate
               which, upon receipt of such request, shall be promptly delivered
               by the Depositor or the Administrative Trustees;

                    (iv) the Property Trustee may consult with counsel of its
               selection 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, suffered or omitted by
               it hereunder in good faith and in reliance thereon;

                    (v) the Property Trustee shall be under no obligation to
               exercise any of the rights or powers vested in it by this Trust
               Agreement at the request or direction of any Securityholder
               pursuant to this Trust Agreement, unless such Securityholder
               shall have offered to the Property Trustee reasonable security or
               indemnity against the costs, expenses (including reasonable
               attorneys' fees and expenses) and liabilities which might be
               incurred by it in complying with such request or direction;

                    (vi) the Property 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, direction, consent, order, approval, bond, debenture,
               note or other evidence of indebtedness or other paper or
               document, but the Property Trustee, in its discretion, may make
               such further inquiry or investigation into such facts or matters
               as it may see fit, and, if the Property Trustee shall determine
               to make such further inquiry or investigation, it shall be
               entitled to examine the books, records and premises of the
               Depositor personally or by agent or attorney;

                                       32
<PAGE>

                    (vii) the Property Trustee may execute any of the trusts or
               powers hereunder or perform any duties hereunder either directly
               or by or through its agents or attorneys, and the Property
               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;

                    (viii) the Property Trustee shall not be liable for any
               action taken, suffered, or omitted to be taken by it in good
               faith and reasonably believed by it to be authorized or within
               the discretion or rights or powers conferred upon it by this
               Trust Agreement;

                    (ix) the Property Trustee shall not be charged with
               knowledge of any default or Event of Default with respect to the
               Trust Securities unless either (A) a Responsible Officer of the
               Property Trustee shall have actual knowledge of the default or
               Event of Default or (B) written notice of such default or Event
               of Default shall have been given to the Property Trustee by the
               Depositor, the Administrative Trustees or by any Holder of the
               Trust Securities;

                    (x) no provision of this Trust Agreement shall be deemed to
               impose any duty or obligation on the Property Trustee to perform
               any act or acts or exercise any right, power, duty or obligation
               conferred or imposed on it in any jurisdiction in which it shall
               be illegal, or in which the Property Trustee shall be unqualified
               or incompetent in accordance with applicable law, to perform any
               such act or acts or to exercise any such right, power, duty or
               obligation; and no permissive or discretionary power or authority
               available to the Property Trustee shall be construed to be a
               duty;

                    (xi) no provision of this Trust Agreement shall require the
               Property 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
               the Property Trustee shall have reasonable grounds for believing
               that the repayment of such funds or liability is not reasonably
               assured to it under the terms of this Trust Agreement or adequate
               indemnity against such risk or liability is not reasonably
               assured to it;

                    (xii) the Property Trustee shall have no duty to see to any
               recording, filing or registration of any instrument (including
               any financing or continuation statement or any tax or securities
               form) (or any rerecording, refiling or registration thereof);

                    (xiii) the Property Trustee shall have the right at any time
               to seek instructions concerning the administration of this Trust
               Agreement from any court of competent jurisdiction; and

                    (xiv) whenever in the administration of this Trust Agreement
               the Property Trustee shall deem it desirable to receive
               instructions with respect to enforcing any remedy or right or
               taking any other action hereunder, the Property Trustee (A) may

                                       33
<PAGE>

               request instructions from the Holders of the Trust Securities,
               which instructions may only be given by the Holders of the same
               Liquidation Amount of the Trust Securities as would be entitled
               to direct the Property Trustee under the terms of this Trust
               Agreement in respect of such remedies, rights or actions, (B) may
               refrain from enforcing such remedy or right or taking such other
               action until such instructions are received, and (C) shall be
               protected in acting in accordance with such instructions.

               SECTION 8.04. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES. The recitals contained herein and in the Trust Securities
Certificates shall be taken as the statements of the Trust, and the Trustees do
not assume any responsibility for their correctness. The Trustees make no
representations as to the title to, or value or condition of, the property of
the Trust or any part thereof, nor as to the validity or sufficiency of this
Trust Agreement, the Debentures or the Trust Securities. The Trustees shall not
be accountable for the use or application by the Trust of the proceeds of the
Trust Securities.

               SECTION 8.05. MAY HOLD SECURITIES. Any Trustee or any agent of
any Trustee or the Trust, in its individual or any other capacity, may become
the owner or pledgee of Trust Securities and, except as provided in the
definition of the term "Outstanding" in Article I, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such agent.

               SECTION 8.06. COMPENSATION; FEES; INDEMNITY.

               The Depositor agrees:

                    (i) to pay to the Trustees from time to time reasonable
               compensation for all services rendered by the Trustees hereunder
               (which compensation shall not be limited by any provision of law
               in regard to the compensation of a trustee of an express trust);

                    (ii) except as otherwise expressly provided herein, to
               reimburse the Trustees upon request for all reasonable expenses,
               disbursements and advances reasonably incurred or made by the
               Trustees in accordance with any provision of this Trust Agreement
               (including the reasonable compensation and the expenses and
               disbursements of its agents and counsel), except any such
               expense, disbursement or advance as may be attributable to its
               negligence (gross negligence, in the case of any Administrative
               Trustee), bad faith or willful misconduct; and

                    (iii) to indemnify each Trustee for, and to hold each
               Trustee harmless against, any and all loss, damage, claims,
               liability or expense incurred without negligence (gross
               negligence, in the case of any Administrative Trustee), bad faith
               or willful misconduct on its part, arising out of or in
               connection with the acceptance or administration of the trust or
               trusts under this Trust Agreement, including the reasonable costs
               and expenses of defending itself against any claim or liability

                                       34
<PAGE>

               in connection with the exercise or performance of any of its
               powers or duties hereunder.

               As security for the performance of the obligations of the
Depositor under this Section, each of the Trustees shall have a lien prior to
the Trust Securities upon all property and funds held or collected by such
Trustee as such, except funds held in trust for the payment of Distributions on
the Trust Securities. "Trustee" for purposes of this Section shall include any
predecessor Trustee; provided, however, that the negligence, wilful misconduct
or bad faith of any Trustee hereunder shall not affect the rights of any other
Trustee hereunder.

               In addition to the rights provided to each Trustee pursuant to
the provisions of the immediately preceding paragraph of this Section 8.06, when
a Trustee incurs expenses or renders services in connection with an Event of
Default resulting from a Bankruptcy Event with respect to the Trust, the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

               The provisions of this Section 8.06 shall survive the termination
of this Trust Agreement.

               SECTION 8.07. CERTAIN TRUSTEES REQUIRED; ELIGIBILITY. (a) There
shall at all times be a Property Trustee hereunder with respect to the Trust
Securities. The Property Trustee shall be a Person that has a combined capital
and surplus of at least $50,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Property Trustee with respect to the Trust
Securities shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article VIII.

               (b) There shall at all times be one or more Administrative
          Trustees hereunder with respect to the Trust Securities. Each
          Administrative Trustee shall be either a natural person who is at
          least 21 years of age or a legal entity that shall act through one or
          more persons authorized to bind such entity.

               (c) There shall at all times be a Delaware Trustee with respect
          to the Trust Securities. The Delaware Trustee shall either be (i) a
          natural person who is at least 21 years of age and a resident of the
          State of Delaware or (ii) a legal entity with its principal place of
          business in the State of Delaware that otherwise meets the
          requirements of applicable Delaware law and that shall act through one
          or more persons authorized to bind such entity.

               SECTION 8.08. CONFLICTING INTERESTS.

               If the Property Trustee has or shall acquire a conflicting

               SECTION 8.09. CO-TRUSTEES AND SEPARATE TRUSTEE.

               Unless an Event of Default shall have occurred and be continuing,
at any time or times, for the purpose of meeting the legal requirements of the
Trust Indenture Act or of any jurisdiction in which any part of the Trust
Property may at the time be located, the Depositor and the Property Trustee
shall have power to appoint, and upon the written request of the Property
Trustee, the Depositor shall for such purpose join with the Property Trustee in
the execution, delivery, and performance of all instruments and agreements
necessary or proper to appoint, one or more Persons approved by the Property
Trustee either to act as co-trustee, jointly with the Property Trustee, of all
or any part of such Trust Property, or to act as separate trustee of any such
property, in either case with such powers as may be provided in the instrument
of appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed necessary or desirable, subject to
the other provisions of this Section. If the Depositor does not join in such
appointment within 15 days after the receipt by it of a request so to do, or in
case a Debenture Event of Default has occurred and is continuing, the Property
Trustee alone shall have power to make such appointment.

               Should any written instrument from the Depositor be required by
any co-trustee or separate trustee so appointed for more fully confirming to
such co-trustee or separate trustee such property, title, right, or power, any
and all such instruments shall, on request, be executed, acknowledged, and
delivered by the Depositor.

               Every co-trustee or separate trustee shall, to the extent
permitted by law, but to such extent only, be appointed subject to the following
terms, namely:

                                       36
<PAGE>

                         (1) The Trust Securities shall be executed and
                    delivered and all rights, powers, duties, and obligations
                    hereunder in respect of the custody of securities, cash and
                    other personal property held by, or required to be deposited
                    or pledged with, the Trustees designated for such purpose
                    hereunder, shall be exercised, solely by such Trustees.

                         (2) The rights, powers, duties, and obligations hereby
                    conferred or imposed upon the Property Trustee in respect of
                    any property covered by such appointment shall be conferred
                    or imposed upon and exercised or performed by the Property
                    Trustee or by the Property Trustee and such co-trustee or
                    separate trustee jointly, as shall be provided in the
                    instrument appointing such co-trustee or separate trustee,
                    except to the extent that under any law of any jurisdiction
                    in which any particular act is to be performed, the Property
                    Trustee shall be incompetent or unqualified to perform such
                    act, in which event such rights, powers, duties, and
                    obligations shall be exercised and performed by such
                    co-trustee or separate trustee.

                         (3) The Property Trustee at any time, by an instrument
                    in writing executed by it, with the written concurrence of
                    the Depositor, may accept the resignation of or remove any
                    co-trustee or separate trustee appointed under this Section
                    8.09, and, in case a Debenture Event of Default has occurred
                    and is continuing, the Property Trustee shall have power to
                    accept the resignation of, or remove, any such co-trustee or
                    separate trustee without the concurrence of the Depositor.
                    Upon the written request of the Property Trustee, the
                    Depositor shall join with the Property Trustee in the
                    execution, delivery, and performance of all instruments and
                    agreements necessary or proper to effectuate such
                    resignation or removal. A successor to any co-trustee or
                    separate trustee so resigned or removed may be appointed in
                    the manner provided in this Section.

                         (4) No co-trustee or separate trustee hereunder shall
                    be personally liable by reason of any act or omission of any
                    Trustee, or any other such trustee hereunder.

                         (5) The Property Trustee shall not be liable by reason
                    of any act of a co-trustee or separate trustee hereunder.

                         (6) Any Act of Holders delivered to the Property
                    Trustee shall be deemed to have been delivered to each such
                    co-trustee and separate trustee.

               SECTION 8.10. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.
No resignation or removal of any Trustee (as the case may be, the "Relevant
Trustee") and no appointment of a successor Relevant Trustee pursuant to this
Article shall become effective until the acceptance of appointment by the

                                       37
<PAGE>

successor Relevant Trustee in accordance with the applicable requirements of
Section 8.11.

               The Relevant Trustee may resign at any time by giving written
notice thereof to the Securityholders. If the instrument of acceptance by a
successor Relevant Trustee required by Section 8.11 shall not have been
delivered to the resigning Relevant Trustee within 30 days after the giving of
such notice of resignation, the resigning Relevant Trustee may petition any
court of competent jurisdiction for the appointment of a successor Relevant
Trustee.

               Unless a Debenture Event of Default shall have occurred and be
continuing, the Relevant Trustee may be removed at any time by Act of the Common
Trust Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Relevant Trustee may be removed at such time by Act of the
Securityholders of a majority of the aggregate Liquidation Amount of the
Outstanding Preferred Trust Securities, delivered to the Relevant Trustee (in
its individual capacity and on behalf of the Trust); provided, however, that any
Administrative Trustee may be removed solely by the Act of the Common Trust
Securityholder.

               If the Relevant Trustee shall resign, be removed or become
incapable of continuing to act as Relevant Trustee at a time when no Debenture
Event of Default shall have occurred and be continuing, the Common Trust
Securityholder, by Act of the Common Trust Securityholder delivered to the
retiring Relevant Trustee, shall promptly appoint a successor Relevant Trustee
or Trustees, and the retiring Relevant Trustee shall comply with the applicable
requirements of Section 8.11. If the Relevant Trustee shall resign, be removed
or become incapable of continuing to act as the Relevant Trustee at a time when
a Debenture Event of Default shall have occurred and be continuing, the
Preferred Trust Securityholders, by Act of the Preferred Trust Securityholders
of a majority in aggregate Liquidation Amount of the Outstanding Preferred Trust
Securities delivered to the retiring Relevant Trustee, shall promptly appoint a
successor Relevant Trustee or Trustees, and the Relevant Trustee shall comply
with the applicable requirements of Section 8.11. If no successor Relevant
Trustee shall have been so appointed by the Common Trust Securityholders or the
Preferred Trust Securityholders and accepted appointment in the manner required
by Section 8.11, any Securityholder who has been a Securityholder of Trust
Securities for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

               The retiring Relevant Trustee shall give notice of each
resignation and each removal of the Relevant Trustee and each appointment of a
successor Trustee to all Securityholders in the manner provided in Section 10.08
and shall give notice to the Depositor. Each notice shall include the name and
address of the successor Relevant Trustee and, in the case of the Property
Trustee, the address of its Corporate Trust Office.

               Notwithstanding the foregoing or any other provision of this
Trust Agreement, in the event any Administrative Trustee or a Delaware Trustee
who is a natural person dies or becomes incompetent or incapacitated, the
vacancy created by such death, incompetence or incapacity may be filled by (i)
the unanimous act of remaining Administrative Trustees if there are at least two
of them or (ii) otherwise by the Depositor (with the successor in each case
being an individual who satisfies the eligibility requirements for
Administrative Trustees or Delaware Trustee, as the case may be, set forth in

                                       38
<PAGE>

Section 8.07). Additionally, notwithstanding the foregoing or any other
provision of this Trust Agreement, in the event the Depositor reasonably
believes that any Administrative Trustee who is a natural person has become
incompetent or incapacitated, the Depositor, by notice to the remaining
Trustees, may terminate the status of such Person as an Administrative Trustee
(in which case the vacancy so created will be filled in accordance with the
preceding sentence).

               No Property Trustee or Delaware Trustee shall be liable for the
acts or omissions to act of any successor Property Trustee or Delaware Trustee.

               SECTION 8.11. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. In case of
the appointment hereunder of a successor Relevant Trustee, the retiring Relevant
Trustee and each successor Trustee shall execute and deliver an amendment hereto
wherein each successor Relevant Trustee shall accept such appointment and which
(1) shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee and (2) shall add to
or change any of the provisions of this Trust Agreement as shall be necessary to
provide for or facilitate the administration of the trusts hereunder by more
than one Relevant Trustee, it being understood that nothing herein or in such
amendment shall constitute such Relevant Trustees co-trustees of the same trust
and that each such Relevant Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Relevant Trustee and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee; but,
on request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Trustee all
Trust Property, all proceeds thereof and money held by such retiring Relevant
Trustee hereunder with respect to the Trust Securities and the Trust.

               Upon request of any such successor Relevant Trustee, the retiring
Relevant Trustee shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Relevant Trustee all such
rights, powers and trusts referred to in the first or second preceding
paragraph, as the case may be.

               No successor Relevant Trustee shall accept its appointment unless
at the time of such acceptance such successor Relevant Trustee shall be
qualified and eligible under this Article VIII.

               SECTION 8.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS. Any Person into which the Property Trustee or the Delaware Trustee or
any Administrative Trustee or any Trustee that is not a natural person may be
merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which such Relevant
Trustee shall be a party, or any Person succeeding to all or substantially all
the corporate trust business of such Relevant Trustee, shall be the successor of
such Relevant Trustee hereunder, provided such Person shall be otherwise
qualified and eligible under this Article VIII, without the execution or filing

                                       39
<PAGE>

of any paper, the giving of any notice or any further act on the part of any of
the parties hereto.

               SECTION 8.13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR
OR TRUST. If and when the Property Trustee shall be or become a creditor of the
Depositor or the Trust (or any other obligor upon the Debentures or the Trust
Securities), the Property Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of claims against the Depositor or
Trust (or any such other obligor).

               SECTION 8.14. REPORTS BY PROPERTY TRUSTEE. (a) The Property
Trustee shall transmit to Securityholders such reports concerning the Property
Trustee and its actions under this Trust Agreement as may be required pursuant
to the Trust Indenture Act at the times and in the manner provided pursuant
thereto. Such of those reports as are required to be transmitted by the Property
Trustee pursuant to Section 313(a) of the Trust Indenture Act shall be dated as
of the next preceding September 15, and shall be transmitted no later than
November 1 of each year, commencing November 1, 2000.

               (b) A copy of each such report shall, at the time of such
          transmission to Holders, be filed by the Property Trustee with each
          stock exchange upon which the Trust Securities are listed, with the
          Commission and with the Depositor. The Depositor will notify the
          Property Trustee when any Trust Securities are listed on any stock
          exchange.

               SECTION 8.15. REPORTS TO THE PROPERTY TRUSTEE. The Depositor and
the Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information, if any, and the compliance
certificate required by Section 314 of the Trust Indenture Act, in the form, in
the manner and at the times required by Section 314 of the Trust Indenture Act.
Delivery of such reports, information and documents by the Depositor to the
Property Trustee is for informational purposes only and the Property Trustee's
receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Depositor's compliance with any of its covenants hereunder (as to which the
Property Trustee is entitled to rely exclusively on Officers' Certificates).

               SECTION 8.16. EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.
Each of the Depositor and the Administrative Trustees on behalf of the Trust
shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement (including
any covenants compliance with which constitutes a condition precedent) that
relate to any of the matters set forth in Section 314(c) of the Trust Indenture
Act. Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) of the Trust Indenture Act may be given in the form of an
Officers' Certificate.

               SECTION 8.17. NUMBER OF TRUSTEES.

               (a) The number of Trustees shall be six, provided that Depositor,
          by written instrument, may increase or decrease the number of
          Administrative Trustees.

                                       40
<PAGE>

               (b) If a Trustee ceases to hold office for any reason and the
          number of Administrative Trustees is not reduced pursuant to Section
          8.17(a), or if the number of Trustees is increased pursuant to Section
          8.17(a), a vacancy shall occur. The vacancy shall be filled with a
          Trustee appointed in accordance with Section 8.10.

               (c) The death, resignation, retirement, removal, bankruptcy,
          incompetence or incapacity to perform the duties of a Trustee shall
          not operate to annul, dissolve or terminate the Trust. Whenever a
          vacancy in the number of Administrative Trustees shall occur, until
          such vacancy is filled by the appointment of an Administrative Trustee
          in accordance with Section 8.10, the Administrative Trustees in
          office, regardless of their number (and notwithstanding any other
          provision of this Agreement), shall have all the powers granted to the
          Administrative Trustees and shall discharge all the duties imposed
          upon the Administrative Trustees by this Trust Agreement.

               SECTION 8.18. DELEGATION OF POWER.

               (a) Any Administrative Trustee may, by power of attorney
          consistent with applicable law, delegate to any other natural person
          over the age of 21 his or her power for the purpose of executing any
          documents contemplated in Sections 2.07(a) and 2.07(c), including any
          registration statement or amendment thereto filed with the Commission,
          or making any other governmental filing; and

               (b) the Administrative Trustees shall have power to delegate from
          time to time to such of their number the doing of such things and the
          execution of such instruments either in the name of the Trust or the
          names of the Administrative Trustees or otherwise as the
          Administrative Trustees may deem expedient, to the extent such
          delegation is not prohibited by applicable law or contrary to the
          provisions of the Trust, as set forth herein.

               SECTION 8.19. FIDUCIARY DUTY.

               (a) To the extent that, at law or in equity, an Indemnified
          Person has duties (including fiduciary duties) and liabilities
          relating thereto to the Trust or to any other Covered Person, an
          Indemnified Person acting under this Trust Agreement shall not be
          liable to the Trust or to any other Covered Person for its good faith
          reliance on the provisions of this Trust Agreement. The provisions of
          this Trust Agreement, to the extent that they restrict the duties and
          liabilities of an Indemnified Person otherwise existing at law or in
          equity (other than the duties imposed on the Property Trustee under
          the Trust Indenture Act), are agreed by the parties hereto to replace
          such other duties and liabilities of such Indemnified Person;

               (b) Unless otherwise expressly provided herein and subject to the
          provisions of the Trust Indenture Act:

                    (i) whenever a conflict of interest exists or arises between
               an Indemnified Person and any Covered Person; or

                                       41
<PAGE>

                    (ii) whenever this Trust Agreement or any other agreement
               contemplated herein or therein provides that an Indemnified
               Person shall act in a manner that is, or provides terms that are,
               fair and reasonable to the Trust or any Holder of Trust
               Securities, the Indemnified Person shall resolve such conflict of
               interest, take such action or provide such terms, considering in
               each case the relative interest of each party (including its own
               interest) to such conflict, agreement, transaction or situation
               and the benefits and burdens relating to such interests, any
               customary or accepted industry practices, and any applicable
               generally accepted accounting practices or principles. In the
               absence of bad faith by the Indemnified Person, the resolution,
               action or term so made, taken or provided by the Indemnified
               Person shall not constitute a breach of this Trust Agreement or
               any other agreement contemplated herein or of any duty or
               obligation of the Indemnified Person at law or in equity or
               otherwise; and

               (c) Unless otherwise expressly provided herein and subject to the
          provisions of the Trust Indenture Act, whenever in this Trust
          Agreement an Indemnified Person is permitted or required to make a
          decision

                    (i) in its "discretion" or under a grant of similar
               authority, the Indemnified Person shall be entitled to consider
               such interests and factors as it reasonably desires, including
               its own interests, and shall have no duty or obligation to give
               any consideration to any interest of or factors affecting the
               Trust or any other Person; or

                    (ii) in its "good faith" or under another express standard,
               the Indemnified Person shall act under such express standard and
               shall not be subject to any other or different standard imposed
               by this Trust Agreement or by applicable law.

                                   ARTICLE IX.

               Issuer;

                    (ii) the redemption of all of the Preferred Trust
               Securities;

                    (iii) an order for judicial dissolution of the Trust having
               been entered by a court of competent jurisdiction;

               distribute the Debentures to the Holders of Preferred Trust
               Securities in liquidation of the Trust;

               SECTION 9.04. Liquidation. (a) Upon the Expiration Date or if an
Early Termination Event specified in clause (i), (iii) or (iv) of Section 9.02
occurs, after satisfaction of creditors of the Trust, if any, as provided by
applicable law, the Trust shall be liquidated by the Property Trustee as
expeditiously as the Property Trustee determines to be appropriate by
distributing to each Securityholder a Like Amount of Debentures, subject to
Section 9.04(e). Notice of liquidation shall be given by the Administrative
Trustees by first-class mail, postage prepaid, mailed not later than 30 nor more
than 60 days prior to the Liquidation Date to each Holder of Trust Securities at
such Holder's address appearing in the Securities Register. All notices of
liquidation shall:

                    (i) state the Liquidation Date;

                    (ii) state that from and after the Liquidation Date, the
               Trust Securities will no longer be deemed to be outstanding and
               any Trust Securities Certificates not surrendered for exchange
               will be deemed to represent a Like Amount of Debentures; and

                    (iii) provide such information with respect to the mechanics
               by which Holders may exchange Trust Securities Certificates for
               Debentures, or, if Section 9.04(e) applies, receive a Liquidation
               Distribution, as the Administrative Trustees or the Property
               Trustee shall deem appropriate.

               (b) Except where Sections 9.02(ii), 9.04(d) or 9.04(e) apply, in
          order to effect the liquidation of the Trust hereunder, and any
          resulting distribution of the Debentures to Securityholders, the
          Property Trustee shall establish a record date for such distribution
          (which shall be not more than 45 days prior to the Liquidation Date)
          and, either itself acting as exchange agent or through the appointment
          of a separate exchange agent, shall establish such procedures as it
          shall deem appropriate to effect the distribution of Debentures in
          exchange for the Outstanding Trust Securities Certificates.

               (c) Except where Sections 9.02(ii), 9.04(d) or 9.04(e) apply,
          after any Liquidation Date, (i) the Trust Securities will no longer be
          deemed to be Outstanding, (ii) certificates representing a Like Amount

                                       43
<PAGE>

          of Debentures will, after satisfaction of liabilities to creditors of
          the Trust, if any, as provided by applicable law, be issued to Holders
          of Trust Securities Certificates, upon surrender of such Trust
          Securities Certificates to the Administrative Trustees or their agent
          for exchange, (iii) any Trust Securities Certificates not so
          surrendered for exchange will be deemed to represent a Like Amount of
          Debentures, accruing interest at the rate provided for in the
          Debentures from the last Distribution Date on which a Distribution was
          made on such Trust Securities Certificates until such Trust Securities
          Certificates are so surrendered (and until such Trust Securities
          Certificates are so surrendered, no payments or interest or principal
          will be made to Holders of Trust Securities Certificates with respect
          to such Debentures) and (iv) all rights of Securityholders holding
          Trust Securities will cease, except the right of such Securityholders
          to receive, after satisfaction of liabilities to creditors of the
          Trust, if any, as provided by applicable law, Debentures upon
          surrender of Trust Securities Certificates.

               (d) If at any time, a Tax Event shall occur and be continuing,
          and either (i) in the opinion of counsel to the Depositor experienced
          in such matters, there would in all cases, after effecting the
          dissolution of the Trust, after satisfaction of liabilities to
          creditors of the Trust, if any, as provided by applicable law, and the
          distribution of the Debentures to the Holders of the Preferred Trust
          Securities in exchange therefor, be more than an insubstantial risk
          that an Adverse Tax Consequence would continue to exist or (ii) the
          Debentures are not held by the Trust, then the Depositor shall have
          the right to redeem the Debentures, in whole but not in part, at any
          time within 90 days following the occurrence of the Tax Event. Whether
          or not a Tax Event has occurred, the Depositor has the right, at any
          time, to dissolve the Trust and, after satisfaction of liabilities to
          creditors of the Trust, if any, as provided by applicable law, cause
          the Debentures to be distributed to the Holders of the Preferred Trust
          Securities and Common Trust Securities in liquidation of the Trust on
          a pro rata basis.

               (e) In the event that, notwithstanding the other provisions of
          this Section 9.04, whether because of an order for dissolution entered
          by a court of competent jurisdiction or otherwise, distribution of the
          Debentures in the manner provided herein is determined by the Property
          Trustee not to be practical, the Trust Property shall be liquidated,
          and the Trust shall be wound-up, by the Property Trustee in such
          manner as the Property Trustee determines. In such event,
          Securityholders will be entitled to receive out of the assets of the
          Trust available for distribution to Securityholders, after
          satisfaction of liabilities to creditors of the Trust, if any, as
          provided by applicable law, an amount equal to the Liquidation Amount
          per Trust Security plus accumulated and unpaid Distributions thereon
          to the date of payment (such amount being the "Liquidation
          Distribution"). If, upon any such winding up, the Liquidation
          Distribution can be paid only in part because the Trust has
          insufficient assets available to pay in full the aggregate Liquidation
          Distribution, then, subject to the next succeeding sentence, the
          amounts payable by the Trust on the Trust Securities shall be paid on
          a pro rata basis (based upon Liquidation Amounts). The Holder of
          Common Trust Securities will be entitled to receive Liquidation
          Distributions upon any such winding-up or termination pro rata
          (determined as aforesaid) with Holders of Preferred Trust Securities,
          except that, if a Debenture Event of Default has occurred and is
          continuing or if a Debenture Event of Default has not occurred solely

                                       44
<PAGE>

          by reason of a requirement that time lapse or notice be given, the
          Preferred Trust Securities shall have a priority over the Common Trust
          Securities.

                                   ARTICLE X.

                            MISCELLANEOUS PROVISIONS

               SECTION 10.01. GUARANTEE BY THE DEPOSITOR AND ASSUMPTION OF
OBLIGATIONS. Subject to the terms and conditions hereof, the Depositor
irrevocably and unconditionally guarantees to each Person to whom the Trust is
now or hereafter becomes indebted or liable (the "Beneficiaries"), and agrees to
assume liability for, the full payment, when and as due, of any and all
Obligations (as hereinafter defined) to such Beneficiaries. As used herein,
"Obligations" means any indebtedness, expenses or liabilities of the Trust,
other than obligations of the Trust to pay to Holders the amounts due such
Holders pursuant to the terms of the Preferred Trust Securities. This guarantee
and assumption is intended to be for the benefit, of, and to be enforceable by,
all such Beneficiaries, whether or not such Beneficiaries have received notice
hereof.

               SECTION 10.02. LIMITATION OF RIGHTS OF SECURITYHOLDERS. The
death, incapacity, bankruptcy, dissolution or termination of any Person having
an interest, beneficial or otherwise, in a Trust Security shall not operate to
terminate this Trust Agreement, nor dissolve, terminate or annul the Trust, nor
entitle the legal representatives or heirs of such Person or any Securityholder
for such Person, to claim an accounting, take any action or bring any proceeding
in any court for a partition or winding up of the arrangements contemplated
hereby, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

               SECTION 10.03. AMENDMENT.

               (a) This Trust Agreement may be amended from time to time by the
          Trust (on approval of a majority of the Administrative Trustees and
          the Depositor, without the consent of any Securityholders or the other
          Trustees), (i) to cure any ambiguity, correct or supplement any
          provision herein or therein which may be inconsistent with any other
          provision herein or therein, or to make any other provisions with
          respect to matters or questions arising under this Trust Agreement,
          (ii) to change the name of the Trust or (iii) to modify, eliminate or
          add to any provisions of this Trust Agreement to such extent as shall
          be necessary to ensure that the Trust will not be classified for
          United States federal income tax purposes other than as a "grantor
          trust" and not as an association taxable as a corporation at any time
          that any Trust Securities are outstanding or to ensure the Trust's
          exemption from the status of an "investment company" under the
          Investment Company Act; provided, however, that such action shall not
          adversely affect in any material respect the interests of any
          Securityholder and, in the case of clause (i), any such amendments of
          this Trust Agreement shall become effective when notice thereof is
          given to the Securityholders.

               (b) Except as provided in Sections 6.01(c) and 10.03(c), any
          provision of this Trust Agreement may be amended by the Administrative
          Trustees and the Depositor with (i) the consent of Holders of Trust

                                       45
<PAGE>

          Securities representing not less than a majority (based upon
          Liquidation Amounts) of the outstanding Trust Securities and (ii)
          receipt by the Trustees of an Opinion of Counsel to the effect that
          such amendment or the exercise of any power granted to the Trustees in
          accordance with such amendment will not affect the Trust's status as a
          grantor trust for federal income tax purposes or the Trust's exemption
          from status as an "investment company" under the Investment Company
          Act.

               (c) In addition to and notwithstanding any other provision in
          this Trust Agreement, without the consent of each affected
          Securityholder, this Trust Agreement may not be amended to (i)
          adversely change the amount or timing of any Distribution on the Trust
          Securities or otherwise adversely affect the amount of any
          Distribution required to be made in respect of the Trust Securities as
          of a specified date or (ii) restrict the right of a Securityholder to
          institute suit for the enforcement of any such payment on or after
          such date.

               (d) Notwithstanding any other provisions of this Trust Agreement,
          no amendment to this Trust Agreement may be made if, as a result of
          such amendment, the Trust would not be classified as a "grantor trust"
          but an association taxable as a corporation for United States federal
          income tax purposes or would to fail or cease to qualify for the
          exemption from status of an "investment company" under the Investment
          Company Act afforded by Rule 3a-5 thereunder.

               (e) Notwithstanding anything in this Trust Agreement to the
          contrary, without the consent of the Depositor and the Trustees, this
          Trust Agreement may not be amended in a manner which imposes any
          additional obligation on the Depositor or any Trustee or, in the case
          of the Trustees, which affects any of their respective rights, duties
          or immunities hereunder.

               (f) In the event that any amendment to this Trust Agreement is
          made, the Administrative Trustees shall promptly provide to the
          Depositor a copy of such amendment.

               (g) The Property Trustee and the Delaware Trustee may join in the
          execution of any amendment to the Trust Agreement and are entitled to
          rely upon an Opinion of Counsel as conclusive evidence that any
          amendment to this Trust Agreement entered into pursuant to this
          Section 10.03 is authorized or permitted by, and conforms to, the
          terms of this Section 10.03, has been duly authorized by and lawfully
          executed and delivered on behalf of the other requisite parties, and
          that it is proper for the Property Trustee under the provisions of
          this Section 10.03 to accept the additional trusts created thereby
          and, if so requested, for the Property Trustee or the Delaware Trustee
          to join in the execution thereof.

               SECTION 10.04. SEPARABILITY. In case any provision in this Trust
Agreement or in the Trust Securities Certificates shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.
