                      CERTAIN TERMS OF THE TRUST SECURITIES

     Section 4.1. 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 -----------------, and shall
be payable quarterly in arrears on [ ], [ ], [ ] and [ ] of each year,
commencing on ---------, 200-- except as provided below. The Sponsor has the
right under the Indenture to defer payments of interest by extending the
interest payment period from time to time on the Debt Securities for a period

                                       14

<PAGE>

not extending, in the aggregate, beyond the maturity date of the Debt Securities
(each, an "Extension Period"). During such Extension Period, no interest shall
be due and payable on the Debt Securities. As a consequence of such deferral,
Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accumulate, compounded quarterly during any such
Extension Period (to the extent permitted by applicable law). Payments of
accrued Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period. Upon the termination of any Extension Period and the payment of all
amounts then due, the Sponsor may commence a new Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed beyond the maturity date of the Debt Securities. If any
date on which a Distribution is 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 that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such next succeeding Business Day
is in the next succeeding calendar year, payment of such Distribution shall be
made on the immediately preceding Business Day, 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 4.1(a), a "Distribution Date").

     (b) The Trust Securities represent undivided beneficial ownership interests
in the Trust Property, and, as a practical matter, the Distributions on the
Trust Securities shall be payable at a rate of ----% per annum (the "Coupon
Rate") of the Liquidation Amount of the Trust Securities. Distributions in
arrears for more than one quarter will accumulate and compound at the Coupon
Rate. The term "Distributions" as used in this Trust Agreement includes such
cash distributions and any such accumulated amounts that are payable unless
otherwise stated. A Distribution is payable only to the extent that payments are
made in respect of the Debt Securities held by the Property Trustee and to the
extent the Property Trustee has funds available therefor. The amount of
Distributions payable for any full period shall be computed on the basis of a
360-day year of twelve 30-day months. The amount of Distributions payable for
any period less than a full Distribution period will be computed on the basis of
a 360-day year of twelve 30-day months and the actual days elapsed in a partial
month in such period.

     (c) Distributions on the Trust Securities shall be made by the Property
Trustee from the Payment Account and shall be payable on each Distribution Date
only to the extent that the Trust has funds then on hand and 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 such Distribution Date; provided, however, that in the
event that the Preferred Securities do not remain in book-entry-only form, the
relevant record date shall be the date 15 days prior to the relevant
Distribution Date.

     Section 4.2. Redemption.

     (a) On each Debt Security Redemption Date and on the stated maturity of the
Debt Securities, the Trust will be required to redeem a Like Amount of Trust
Securities at the Redemption Price.

     (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 shall state:

          (i) the Redemption Date;

          (ii) the Redemption Price;

          (iii) the CUSIP number;

          (iv) if fewer 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;

          (v) that on the Redemption Date the Redemption Price 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; and

          (vi) if the Preferred Securities are no longer in book-entry-only
     form, the place and address where the Holders shall surrender their
     Preferred Securities Certificates.

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

     (d) If the Property Trustee gives a notice of redemption in respect of any
Trust Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), the Property Trustee will, so long as the Trust
Securities are in book-entry-only form, irrevocably deposit with the Clearing
Agency for the Trust Securities funds sufficient to pay the applicable
Redemption Price and will give such Clearing Agency irrevocable instructions and
authority to pay the Redemption Price to the holders thereof. If the Trust
Securities are no longer in book-entry-only form, the Property Trustee, subject
to Section 4.2(c), will irrevocably deposit with the Paying Agent funds
sufficient to pay the applicable Redemption Price and will give the Paying Agent
irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof upon surrender of their Trust Securities Certificates.
Notwithstanding the foregoing, Distributions payable 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 Register for the
Trust Securities on the relevant record dates for the related Distribution

                                       16

<PAGE>

Dates. If notice of redemption shall have been given and funds deposited as
required, then immediately prior to the close of business (New York City time)
on the date of such deposit, all rights of Securityholders holding Trust
Securities so called for redemption will cease, except the right of such
Securityholders to receive the Redemption Price and any unpaid Distribution
payable on or prior to the Redemption Date, but in each case without interest,
and such Securities will cease to be outstanding. In the event that any date on
which any Redemption Price is payable is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), except that, if such succeeding Business Day falls in the next
calendar year, such payment will be made on the immediately preceding Business
Day, in each case, with the same force and effect as if made on such date. In
the event that payment of the Redemption Price in respect of any Trust
Securities called for redemption is improperly withheld or refused and not paid
either by the Trust or by the Sponsor pursuant to the Guarantee, Distributions
on 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 is actually deposited, in which
case such date will be the date fixed for redemption for purposes of calculating
the Redemption Price provided, that if the Redemption Price is not deposited by
12:00 noon on such date, the next succeeding Business Day shall be the date
fixed for redemption for purposes of calculating the Redemption Price.

     (e) Payment of the Redemption Price on the Trust Securities shall be made
to the recordholders 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 Redemption Date; provided, however, that in the event that
the Preferred Securities do not remain in book-entry-only form, the relevant
record date shall be the date 15 days prior to the relevant Redemption Date.

     (f) Subject to Section 4.3(a), if fewer 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 on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities. The particular Preferred 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 Securities not previously called
for redemption by such method as the Property Trustee shall deem fair and
appropriate. The Property Trustee shall promptly notify the Security Registrar
in writing of the Preferred Securities selected for redemption and, in the case
of any Preferred 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 Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed.

     Section 4.3. Subordination of Common Securities.

     (a) Payment of Distributions on, and the Redemption Price of, the Trust
Securities, as applicable, shall be made, subject to Section 4.2(f), pro rata
among the Common Securities and the Preferred Securities based on the
Liquidation Amount of the Trust Securities; provided, however, that if on any
Distribution Date or Redemption Date any Event of Default resulting from an

                                       17

<PAGE>

Event of Default with respect to any Debt Security shall have occurred and be
continuing, no payment of any Distribution on, or Redemption Price of, any
Common Security, and no other payment on account of the redemption, liquidation
or other acquisition of Common Securities, shall be made unless payment in full
in cash of all accumulated and unpaid Distributions on all Outstanding Preferred
Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred 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 on, or the
Redemption Price of, Preferred Securities then due and payable.

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

     Section 4.4. Payment Procedures.

     Payments of Distributions in respect of the Preferred 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 Securities
are held by a Clearing Agency, such Distributions shall be made to the Clearing
Agency in immediately available funds, which shall credit the relevant Persons'
accounts at such Clearing Agency on the applicable distribution dates. Payments
in respect of the Common Securities shall be made in such manner as shall be
mutually agreed between the Property Trustee and the Common Securityholder.

     Section 4.5. Tax Returns and Reports.

     The Administrative Trustees shall prepare (or cause to be prepared), at the
Sponsor's expense, 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 and filed) the appropriate Internal Revenue Service
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 appropriate Internal Revenue Service form required to be
provided or the information required to be provided on such form. The
Administrative Trustees shall provide the Sponsor and the Property Trustee with
a copy of all such returns and reports 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 4.6. Payments under Indenture.

     Any amount payable hereunder to any Holder of Preferred Securities (and any
Owner with respect thereto) shall be reduced by the amount of any corresponding

the Indenture.

     Section 5.1. Initial Ownership.

     Upon the creation of the Trust and the contribution by the Sponsor pursuant
to Section 2.3 and until the issuance of the Trust Securities, and at any time
during which no Trust Securities are outstanding, the Sponsor shall be the sole
beneficial owner of the Trust.

     Section 5.2. The Trust Securities Certificates.

     The Preferred Securities Certificates shall be issued in minimum
denominations of $[ ] Liquidation Amount and integral multiples of $[ ] in
excess thereof, and the Common Securities Certificates shall be issued in
denominations of $[ ] Liquidation Amount and integral multiples of $[ ] in
excess thereof. The Trust Securities Certificates shall be executed on behalf of
the Trust by manual signature of at least one Administrative Trustee. Trust
Securities Certificates bearing the manual signatures of individuals who were,
at the time when such signatures shall have been affixed, authorized to sign on
behalf of the Trust, 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 Securities Certificate shall
become a Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.11
and 5.13.

     Section 5.3. Execution and Delivery of Trust Securities Certificates.

     At each Time of Delivery, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Sponsor, signed by its Chairman or a Vice Chairman
of the Board, President or a Vice President, and by its Treasurer, Assistant
Treasurer, Comptroller, an Assistant Comptroller, Secretary or an Assistant
Secretary without further corporate action by the Sponsor, in authorized
denominations.

     Section 5.4. Registration of Transfer and Exchange of Preferred Securities
Certificates.

     The Sponsor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (the "Securities Register") in which, the

                                       19

<PAGE>

registrar designated by the Sponsor (the "Securities Registrar"), subject to
such reasonable regulations as it may prescribe, shall provide for the
registration of Preferred Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided. The Bank shall be the initial
Securities Registrar.

     Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or agency maintained pursuant to Section 5.8, the
Administrative Trustees or any one of them shall execute and deliver, in the
name of the designated transferee or transferees, one or more new Preferred
Securities Certificates in authorized denominations of a like aggregate
Liquidation Amount dated the date of execution by such Administrative Trustee or
Trustees.

     The Securities Registrar shall not be required to register the transfer of
any Preferred Securities that have been called for redemption. At the option of
a Holder, Preferred Securities Certificates may be exchanged for other Preferred
Securities Certificates in authorized denominations of the same class and of a
like aggregate Liquidation Amount upon surrender of the Preferred Securities
Certificates to be exchanged at the office or agency maintained pursuant to
Section 5.8.

     Every Preferred 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 Property Trustee and the
Securities Registrar duly executed by the Holder or his attorney duly authorized
in writing. Each Preferred Securities Certificate surrendered for registration
of transfer or exchange shall be cancelled and subsequently disposed of by the
Property Trustee in accordance with its customary practice.

     No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but the Securities 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
Securities Certificates.

     Section 5.5. Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates.

     If (a) any mutilated Trust Securities Certificate shall be surrendered to
the Securities Registrar, or if the Securities 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 Securities Registrar and the
Administrative Trustees such security or indemnity as may be required by them to
save each of them 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 and 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 Securities Registrar may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection therewith. Any duplicate Trust Securities Certificate issued
pursuant to this Section shall constitute conclusive evidence of an undivided
beneficial ownership interest in the assets of the Trust, as if originally

                                       20

<PAGE>

issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

     Section 5.6. Persons Deemed Securityholders.

     The Administrative Trustees or the Securities Registrar shall 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 Securities Registrar shall be bound by any notice
to the contrary.

     Section 5.7. Access to List of Securityholders' Names and Addresses.

     In the event that the Property Trustee is no longer the Securities
Registrar, the Administrative Trustees or the Sponsor shall furnish or cause to
be furnished a list, in such form as the Property Trustee may reasonably
require, of the names and addresses of the Securityholders as of the most recent
record date (a) to the Property Trustee, quarterly not later than 10 days prior
to a Distribution Date and (b) to the Property Trustee, promptly after receipt
by the Administrative Trustees or the Sponsor of a request therefor from the
Property Trustee in order to enable the Paying Agent to pay Distributions in
accordance with Section 4.1 hereof, in each case to the extent such information
is in the possession or control of the Administrative Trustees or the Sponsor
and is not identical to a previously supplied list or has not otherwise been
received by the Property Trustee. The rights of Securityholders to communicate
with other Securityholders with respect to their rights under this Declaration
or under the Trust Securities, and the corresponding rights of the Property
Trustee shall be provided in the Trust Indenture Act. Each Holder, by receiving
and holding a Trust Securities Certificate, and each Owner shall be deemed to
have agreed not to hold the Sponsor, the Property Trustee or the Administrative
Trustees accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

     Section 5.8. Maintenance of Office or Agency.

     The Administrative Trustees shall maintain an office or offices or agency
or agencies where Preferred Securities Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Trustees in respect of the Trust Securities Certificates may be served. The
Administrative Trustees initially designate the office of the Bank as its
principal corporate trust office for such purposes. The Administrative Trustees
shall give prompt written notice to the Sponsor and to the Securityholders of
any change in the location of the Securities Register or any such office or
agency.

     Section 5.9. 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
Property Trustee and the Administrative Trustees. 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 Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its

                                       21

<PAGE>

obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Bank, and any co-paying agent chosen by the Bank, and
acceptable to the Administrative Trustees and the Sponsor. Any Person acting as
Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Administrative Trustees, the Property Trustee and the Sponsor. In
the event that the Bank shall no longer be the Paying Agent or a successor
Paying Agent shall resign or its authority to act be revoked, the Administrative
Trustees shall appoint a successor that is acceptable to the Property Trustee
and the Sponsor to act as Paying Agent (which shall be a bank or trust company).
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 removal of a Paying Agent such Paying Agent shall also
return all funds in its possession to the Property Trustee. The provisions of
Sections 8.1, 8.3 and 8.6 herein shall apply to the Bank also in its role as
Paying Agent, for so long as the Bank shall act as Paying Agent and, to the
extent applicable, to any other paying agent appointed hereunder. Any reference
in this Agreement to the Paying Agent shall include any co-paying agent unless
the context requires otherwise.

     Section 5.10. Ownership of Common Securities by Sponsor.

     At each Time of Delivery, the Sponsor shall acquire and retain beneficial
and record ownership of the Common Securities. To the fullest extent permitted
by law, other than transactions permitted by Section XI of the Indenture, any
attempted transfer of the Common Securities shall be void. The Administrative
Trustees shall cause each Common Securities Certificate issued to the Sponsor to
contain a legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE" OTHER THAN IN
ACCORDANCE WITH THE TRUST AGREEMENT (AS DEFINED BELOW).

     Section 5.11. Book-Entry Preferred Securities Certificates; Common
Securities Certificate.

     (a) The Preferred Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to The Depository Trust Company, the initial Clearing Agency, by, or
on behalf of, the Trust. Such Preferred Securities Certificate or Certificates
shall initially be registered on the Securities Register in the name of Cede &
Co., the nominee of the initial Clearing Agency, and no beneficial owner will
receive a Definitive Preferred Securities Certificate representing such
beneficial owner's interest in such Preferred Securities, except as provided in
Section 5.13. Unless and until Definitive Preferred Securities Certificates have
been issued to beneficial owners pursuant to Section 5.13:

          (i) the provisions of this Section 5.11(a) shall be in full force and
     effect;

                                       22

<PAGE>

          (ii) the Securities Registrar and the Trustees shall be entitled to
     deal with the Clearing Agency for all purposes of this Trust Agreement
     relating to the Book-Entry Preferred Securities Certificates (including the
     payment of the Liquidation Amount of and Distributions on the Book-Entry
     Preferred Securities and the giving of instructions or directions to Owners
     of Book-Entry Preferred Securities) as the sole Holder of Book-Entry
     Preferred Securities and shall have no obligations to the Owners thereof;

          (iii) to the extent that the provisions of this Section 5.11 conflict
     with any other provisions of this Trust Agreement, the provisions of this
     Section 5.11 shall control; and

          (iv) the rights of the Owners of the Book-Entry Preferred Securities
     Certificates shall be exercised only through the Clearing Agency and shall
     be limited to those established by law and agreements between such Owners
     and the Clearing Agency and/or the Clearing Agency Participants. Pursuant
     to the Certificate Depository Agreement, unless and until Definitive
     Preferred Securities Certificates are issued pursuant to Section 5.13, the
     initial Clearing Agency will make book-entry transfers among the Clearing
     Agency Participants and receive and transmit payments on the Preferred
     Securities to such Clearing Agency Participants.

     (b) A single Common Securities Certificate representing the Common
Securities shall be issued to the Sponsor in the form of a definitive Common
Securities Certificate.

     Section 5.12. Notices to Clearing Agency.

     To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

     Section 5.13. Definitive Preferred Securities Certificates.

     If (a) the Sponsor advises the Trustees in writing that the Clearing Agency
is no longer willing or able to properly discharge its responsibilities with
respect to the Preferred Securities Certificates, and the Sponsor is unable to
locate a qualified successor, (b) the Sponsor at its option advises the Trustees
in writing that it elects to terminate the book-entry system through the
Clearing Agency or (c) after the occurrence of an Event of Default with respect
to any Debt Security, Owners of Preferred Securities Certificates representing
beneficial ownership interests aggregating at least a majority of the
Liquidation Amount advise the Property Trustee in writing that the continuation
of a book-entry system through the Clearing Agency is no longer in the best
interest of the Owners of Preferred Securities Certificates, then the Property
Trustee shall notify the Clearing Agency and the Clearing Agency shall notify
all Owners of Preferred Securities Certificates and the other Trustees of the
occurrence of any such event and of the availability of the Definitive Preferred
Securities Certificates to Owners of such class or classes, as applicable,
requesting the same. Upon surrender to the Property Trustee of the typewritten

                                       23

<PAGE>

Preferred Securities Certificate or Certificates representing the Book Entry
Preferred Securities Certificates by the Clearing Agency, accompanied by
registration instructions, the Administrative Trustees, or any one of them,
shall execute the Definitive Preferred Securities Certificates in accordance
with the instructions of the Clearing Agency. Neither the Securities Registrar
nor the 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. Upon the issuance of Definitive Preferred Securities Certificates,
the Trustees shall recognize the Holders of the Definitive Preferred Securities
Certificates as Securityholders. The Definitive Preferred Securities
Certificates shall be 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.

     Section 5.14. Rights of Securityholders.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial ownership interests 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. By acceptance of a
beneficial interest in the Trust Securities, Holders agree to treat the Debt
Securities as indebtedness for all United States tax purposes. The Trust
Securities shall have no preemptive or similar rights and when issued and
delivered to Securityholders against payment of the purchase price therefor will
be fully paid and nonassessable by the Trust. The Holders of the Trust
Securities, in their capacities as such, shall be entitled to the same
limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware.

     (b) For so long as any Preferred Securities remain Outstanding, if, upon an
Event of Default with respect to any Debt Security, the Indenture Trustee fails
or the holders of not less than 25% in aggregate principal amount of the
outstanding Debt Securities fail to declare the principal of all of the Debt
Securities to be immediately due and payable, the Holders of at least 25% in
aggregate Liquidation Amount of the Preferred Securities then Outstanding shall
have such right by a notice in writing to the Sponsor and the Indenture Trustee;
and upon any such declaration such principal amount of and the accrued interest
on all of the Debt Securities shall become immediately due and payable, provided
that the payment of principal and interest on such Debt Securities shall remain
subordinated to the extent provided in the Indenture. At any time after such a
declaration of acceleration with respect to the Debt Securities has been made
and before a judgment or decree for payment of the money due has been obtained
by the Indenture Trustee as in the Indenture provided, the Holders of a majority
in Liquidation Amount of the Preferred Securities, by written notice to the
Property Trustee, the Sponsor and the Indenture Trustee, may rescind and annul
such declaration and its consequences if:

          (i) the Sponsor has paid or deposited with the Indenture Trustee a sum
     sufficient to pay

                                       24

<PAGE>

               (A) all overdue installments of interest on all of the Debt
          Securities,

               (B) the principal of (and premium, if any, on) any Debt
          Securities which have become due otherwise than by such declaration of
          acceleration and interest thereon at the rate borne by the Debt
          Securities, and

               (C) all sums paid or advanced by the Indenture Trustee under the
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Indenture Trustee and the Property Trustee, their
          agents and counsel; and

          (ii) all Events of Default with respect to the Debt Securities, other
     than the non-payment of the principal of the Debt Securities which has
     become due solely by such acceleration, have been cured or waived as
     provided in Section 6.1 of the Indenture.

     The Holders of a majority in aggregate Liquidation Amount of the Preferred
Securities may, on behalf of the Holders of all the Preferred Securities, waive
any past default if a sum sufficient to pay all matured installments of interest
and principal (and premium, if any) due otherwise than by acceleration has been
deposited with the Indenture Trustee except a default in respect of a covenant
or provision which under the Indenture cannot be modified or amended without the
consent of the holder of each outstanding Debt Security. No such rescission
shall affect any subsequent default or impair any right consequent thereon.

     (c) For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon an Event of Default with respect to any Debt Security
specified in Section 6.1 of the Indenture, any Holder of Preferred Securities
shall have the right to institute a proceeding directly against the Sponsor,
pursuant to the Indenture, for enforcement of payment to such Holder of the
principal amount of or interest on Debt Securities having a principal amount
equal to the Liquidation Amount of the Preferred Securities of such Holder (a
"Direct Action"). In connection with any such Direct Action, the Holder of the
Common Securities will be subrogated to the rights of any Holder of the
Preferred Securities to the extent of any payment made by the Sponsor to such
Holder of Preferred Securities as a result of such Direct Action. Except as set
forth in Section 5.14(b) and (c), the Holders of Preferred Securities shall have
no right to exercise directly any right or remedy available to the holders of,
or in respect of, the Debt Securities.

                                  Article VI.
                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

     Section 6.1. Limitations on Voting Rights.

     (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 and
in the Indenture and as otherwise required by law, no Holder of Preferred
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

                                       25

<PAGE>

of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

     (b) So long as any Debt Securities 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 Indenture Trustee, or executing any
trust or power conferred on the Indenture Trustee with respect to such Debt
Securities, (ii) waive any past default which is waivable under Section 6.1 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debt Securities shall be due and payable or (iv)
consent to any amendment, modification or termination of the Indenture or the
Debt Securities, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of at least a majority in
Liquidation Amount of all Outstanding Preferred Securities, provided, however,
that where a consent under the Indenture would require the consent of each
Holder of Debt Securities affected thereby, no such consent shall be given by
the Property Trustee without the prior written consent of each Holder of
Preferred Securities. The Trustees shall not revoke any action previously
authorized or approved by a vote of the Holders of Preferred Securities, except
by a subsequent vote of the Holders of Preferred Securities. The Property
Trustee shall notify all Holders of the Preferred Securities of any notice of
default received from the Indenture Trustee with respect to the Debt Securities.
In addition to obtaining the foregoing approvals of the Holders of the Preferred
Securities, prior to taking any of the foregoing actions, the Trustees shall, at
the expense of the Sponsor, obtain an Opinion of Counsel experienced in such
matters to the effect that the Trust will not be classified 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 adversely affect
in any material respect the powers, preferences or special rights of the
Preferred 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 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 a majority in Liquidation
Amount of the Outstanding Preferred Securities. Notwithstanding any other
provision of this Trust Agreement, no amendment to this Trust Agreement may be
made if, as a result of such amendment, the Trust would be classified as an
association taxable as a corporation for United States Federal income tax
purposes.

     Section 6.2. Notice of Meetings.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, 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.

                                       26

<PAGE>

     Section 6.3. Meetings of Preferred Securityholders.

     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 Preferred Securityholders of
record of 25% in aggregate Liquidation Amount of the Preferred Securities (based
upon their Liquidation Amount) and the Administrative Trustees or the Property
Trustee may, at any time in their discretion, call a meeting of Preferred
Securityholders to vote on any matters as to which Preferred Securityholders are
entitled to vote.

     Preferred Securityholders of record of 50% of the Outstanding Preferred
Securities (based upon their 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 Preferred
Securityholders of record present, in person or by proxy, holding a majority of
the Preferred Securities (based upon their Liquidation Amount) held by the
Preferred Securityholders of record present, either in person or by proxy, at
such meeting shall constitute the action of the Securityholders, unless this
Trust Agreement requires a greater number of affirmative votes.

     Section 6.4. Voting Rights.

     Securityholders shall be entitled to one vote for each $[ ] of Liquidation
Amount represented by their Trust Securities in respect of any matter as to
which such Securityholders are entitled to vote.

     Section 6.5. 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.
Pursuant to a resolution of the Property Trustee, proxies may be solicited in
the name of the Property Trustee or one or more officers of the Property
Trustee. 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, and the burden of
proving invalidity shall rest on the challenger. No proxy shall be valid more
than three years after its date of execution.

     Section 6.6. Securityholder Action by Written Consent.

     Any action which may be taken by Securityholders at a meeting may be taken
without a meeting if Securityholders holding a majority of all Outstanding Trust
Securities (based upon their Liquidation Amount) entitled to vote in respect of

                                       27

<PAGE>

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.

     Section 6.7. 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 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 a distribution or other action, as the case may be, as a record date
for the determination of the identity of the Securityholders of record for such
purposes.

     Section 6.8. 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 an Administrative Trustee. 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 8.1) conclusive in favor
of the Trustees, if made in the manner provided in this Section.

     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
acknowledgments 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 receiving the same deems sufficient.

     The ownership of Preferred 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

                                       28

<PAGE>

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 the Securityholders and the
Administrative Trustees or among such Securityholders or 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 6.9. Inspection of Records.

     Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the 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.

     as one of the Trustees under this Trust Agreement.

     Section 7.3. Representations and Warranties of Sponsor.

     The Sponsor hereby represents and warrants for the benefit of the
Securityholders that:

     (a) the Trust Securities Certificates issued at each Time of Delivery on
behalf of the Trust have been duly authorized and will have been, duly and
validly executed, issued and delivered by the Administrative Trustees pursuant

                                 Article VIII.
                                  THE TRUSTEES

     Section 8.1. Certain Duties and Responsibilities.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, subject to the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
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. 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.

                                       31

<PAGE>

Nothing in this Trust Agreement shall be construed to release the Property
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct. To the extent that, at law or in equity,
an Administrative Trustee or the Delaware Trustee has duties (including
fiduciary duties) and liabilities relating thereto to the Trust or to the
Securityholders, such Administrative Trustee or Delaware Trustee shall not be
liable to the Trust or to any Securityholder for such Trustee's 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 the
Administrative Trustees or the Delaware Trustee otherwise existing at law or in
equity, are agreed by the Sponsor and the Securityholders to replace such other
duties and liabilities of such Trustees.

     (b) All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the Property Trustee or a 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
revenue and proceeds from the Trust Property to the extent legally 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 8.1(b)
does not limit the liability of the Trustees expressly set forth elsewhere in
this Trust Agreement and, in the case of the Property Trustee, in the Trust
Indenture Act.

     (c) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own negligent action or its own
negligent failure to act, except that:

          (i) the Property Trustee shall not be liable for any error of judgment
     made in good faith by an authorized officer of the Property Trustee, unless
     it shall be proved that the Property Trustee was negligent in ascertaining
     the pertinent facts;

          (ii) the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of not less than a majority in Liquidation
     Amount of the Trust Securities relating to the time, method and place of
     conducting any proceeding for any remedy available to the Property Trustee,
     or exercising any trust or power conferred upon the Property Trustee under
     this Trust Agreement;

          (iii) the Property Trustee's sole duty with respect to the custody,
     safe keeping and physical preservation of the Debt Securities and the
     Payment Account 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 and limitations on liability afforded to the
     Property Trustee under this Trust Agreement and the Trust Indenture Act;

          (iv) the Property Trustee shall not be liable for any interest on any
     money received by it except as it may otherwise agree with the Sponsor; and
     money held by the Property Trustee need not be segregated from other funds
     held by it except in relation to the Payment Account maintained by the

                                       32

<PAGE>

     Property Trustee pursuant to Section 3.1 and except to the extent otherwise
     required by law; and

          (v) the Property Trustee shall not be responsible for monitoring the
     compliance by the Administrative Trustees or the Sponsor 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 Sponsor.

     Section 8.2. Certain Notices.

     Within 90 days after the occurrence of any default actually known to the
Property Trustee, the Property Trustee shall transmit, in the manner and to the
extent provided in Section 10.8, notice of such default to the Securityholders,
the Administrative Trustees and the Sponsor, unless such default shall have been
cured or waived before the giving of such notice (the term "default" or
"defaults" for the purposes of this Section being hereby defined to mean any
event or condition which is, or with notice or lapse of time or both would
become, an Event of Default); provided that, except in the case of default in
the payment of the principal of, or premium, if any, or interest, if any, on,
any of the Debt Securities of such series, the Property Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors or responsible
officers of the Property Trustee in good faith determines that the withholding
of such notice is in the interests of the Securityholders of such series.

     Within five Business Days after the receipt of notice of the Sponsor's
exercise of its right to defer the payment of interest on the Debt Securities
pursuant to the Indenture, the Administrative Trustee shall transmit, in the
manner and to the extent provided in Section 10.8, notice of such exercise to
the Securityholders and the Property Trustee, unless such exercise shall have
been revoked.

     Section 8.3. Certain Rights of Property Trustee.

     Subject to the provisions of Section 8.1:

          (a) 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, consent, order, appraisal, bond, Debt
     Security, note, other evidence of indebtedness or other paper or document
     believed by it to be genuine and to have been signed or presented by the
     proper party or parties; provided, however, that the Property Trustee shall
     examine the evidence furnished to it pursuant to Section 314 of the Trust
     Indenture Act to determine whether or not such evidence conforms to the
     requirements of this Trust Agreement;

          (b) if (i) in performing its duties under this Trust Agreement the
     Property Trustee is required to decide between alternative courses of
     action or (ii) in construing any of the provisions of this Trust Agreement
     the Property Trustee finds the same ambiguous or inconsistent with any
     other provisions contained herein or (iii) the Property Trustee is unsure
     of the application of any provision of this Trust Agreement, then, except

                                       33

<PAGE>

     as to any matter as to which the Preferred Securityholders are entitled to
     vote under the terms of this Trust Agreement, the Property Trustee shall
     deliver a notice to the Sponsor requesting written instructions of the
     Sponsor as to the course of action to be taken and 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 Sponsor; provided, however, that if the Property Trustee does not
     receive such instructions of the Sponsor 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;

          (c) any direction or act of the Sponsor or the Administrative Trustees
     contemplated by this Trust Agreement shall be sufficiently evidenced by an
     Officers' Certificate;

          (d) whenever in the administration of this Trust Agreement, the
     Property Trustee shall deem it desirable that a matter be established
     before undertaking, suffering or omitting any action hereunder, the
     Property Trustee (unless other evidence is 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 Sponsor or the Administrative Trustees;

          (e) 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 filing under tax or securities laws) or any
     rerecording, refiling or reregistration thereof;

          (f) the Property Trustee may consult with counsel (which counsel may
     be counsel to the Sponsor or any of its Affiliates, and may include any of
     its employees) and the advice of such 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 and in
     accordance with such advice, such counsel may be counsel to the Sponsor or
     any of its Affiliates, and may include any of its employees; 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;

          (g) 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 of the Securityholders pursuant to this Trust
     Agreement, unless such Securityholders shall have offered to the Property
     Trustee reasonable security or indemnity against the costs, expenses and

     instrument, opinion, report, notice, request, consent, order, approval,
     bond, Debt Security, note or other evidence of indebtedness or other paper
     or document, unless requested in writing to do so by one or more

     selection of any agent or attorney appointed by it hereunder;

          (j) 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 (i) may request instructions from the
     Holders of the Trust Securities which instructions may only be given by the
     Holders of the same proportion in Liquidation Amount of the Trust
     Securities as would be entitled to direct the Property Trustee under the
     terms of the Trust Securities in respect of such remedy, right or action,
     (ii) may refrain from enforcing such remedy or right or taking such other
     action until such instructions are received, and (iii) shall be protected
     in acting in accordance with such instructions; and

          (k) except as otherwise expressly provided by this Trust Agreement,
     the Property Trustee shall not be under any obligation to take any action
     that is discretionary under the provisions of this Trust Agreement.

     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. No
permissive power or authority available to the Property Trustee shall be
construed to be a duty.

Trust with the same rights it would have if it were not a Trustee or such other
agent.

     The Sponsor, as borrower, agrees:

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

          (b) except as otherwise expressly provided herein, to reimburse the
     Trustees upon request for all reasonable expenses, disbursements and

     whatsoever incurred by such Indemnified Person by reason of the creation,
     operation or termination of the Trust or any act or omission performed or
     omitted by such Indemnified Person in good faith on behalf of the Trust and
     in a manner such Indemnified Person reasonably believed to be within the
     scope of authority conferred on such Indemnified Person by this Trust
     Agreement, except that no Indemnified Person shall be entitled to be
     indemnified in respect of any loss, damage or claim to the extent incurred
     by such Indemnified Person by reason of its own gross negligence (and, in
     the case of the Property Trustee, ordinary negligence) or willful
     misconduct with respect to such acts or omissions.

          (d) to the fullest extent permitted by applicable law, to advance
     expenses (including legal fees) incurred by an Indemnified Person in

     Section 8.7. Corporate Property Trustee Required; Eligibility of Trustees.

     (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 is eligible
pursuant to the Trust Indenture Act to act as such and 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.

     (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 that
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 and
that otherwise meets the requirements of applicable Delaware law that shall act

     Section 8.8. Conflicting Interests.

     If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement. The Sponsor and any Trustee may engage in or possess an interest in
other business ventures of any nature or description, independently or with
others, similar or dissimilar to the business of the Trust, and the Trust and
the Holders of Trust Securities shall have no rights by virtue of this Trust
Agreement in and to such independent ventures or the income or profits derived
therefrom, and the pursuit of any such venture, even if competitive with the
business of the Trust, shall not be deemed wrongful or improper. Neither the
Sponsor, nor any Trustee, shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and the
Sponsor or any Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity. Any Trustee may engage or be
interested in any financial or other transaction with the Sponsor or any
Affiliate of the Sponsor, or may act as Depository for, trustee or agent for, or
act on any committee or body of holders of, securities or other obligations of
the Sponsor or its Affiliates.

Section 8.9.      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 Sponsor and the Administrative Trustees, by agreed
action of the majority of such Trustees, shall have power to appoint, and upon
the written request of the Administrative Trustees, the Sponsor shall for such
purpose join with the Administrative Trustees 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 the extent required by law 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 Sponsor does not join in such
appointment within 15 days after the receipt by it of a request so to do, or in
case an Event of Default with respect to any Debt Security has occurred and is
continuing, the Property Trustee alone shall have power to make such
appointment. Any co-trustee or separate trustee appointed pursuant to this
Section shall either be (i) a natural person who is at least 21 years of age and
a resident of the United States or (ii) a legal entity with its principal place
of business in the United States that shall act through one or more persons
authorized to bind such entity.

     Should any written instrument from the Sponsor 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 Sponsor.

     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:

     (a) 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 specified hereunder, shall be exercised,
solely by such Trustees and not by such co-trustee or separate trustee.

     (b) 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.

     (c) The Property Trustee at any time, by an instrument in writing executed
by it, with the written concurrence of the Sponsor, may accept the resignation

                                       38

<PAGE>

of or remove any co-trustee or separate trustee appointed under this Section,
and, in case an Event of Default with respect to any Debt Security 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 Sponsor. Upon the written request of the Property Trustee,
the Sponsor 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.

     (d) No co-trustee or separate trustee hereunder shall be personally liable
by reason of any act or omission of the Property Trustee or any other trustee
hereunder.

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

     (f) 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 (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.

     Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time by giving written notice thereof to the Securityholders. If
the instrument of acceptance by the successor Trustee required by Section 8.11
shall not have been delivered to the Relevant Trustee within 30 days after the
giving of such notice of resignation, the Relevant Trustee may petition
(pursuant to the Indenture, at the expense of the Sponsor), any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.

     Unless an Event of Default with respect to any Debt Security shall have
occurred and be continuing, any Trustee may be removed at any time by Act of the
Common Securityholder. If an Indenture Event of Default shall have occurred and
be continuing, the Property Trustee or the Delaware Trustee, or both of them,
may be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Common Securityholder at any time.

     If any Trustee shall resign, be removed or become incapable of acting as
Trustee, or if a vacancy shall occur in the office of any Trustee for any cause,
at a time when no Event of Default with respect to any Debt Security shall have
occurred and be continuing, the Common Securityholder, by Act of the Common
Securityholder delivered to the retiring Trustee, shall promptly appoint a
successor Trustee or Trustees, and the retiring Trustee shall comply with the
applicable requirements of Section 8.11. If the Property Trustee or the Delaware
Trustee shall resign, be removed or become incapable of continuing to act as the
Property Trustee or the Delaware Trustee, as the case may be, at a time when an
Event of Default with respect to any Debt Security shall have occurred and be

                                       39

<PAGE>

continuing, the Preferred Securityholders, by Act of the Securityholders of a
majority in Liquidation Amount of the Preferred Securities then Outstanding
delivered to the retiring Relevant Trustee, shall promptly appoint a successor
Relevant Trustee or Trustees, and such successor Trustee shall comply with the
applicable requirements of Section 8.11.

     If an Administrative Trustee shall resign, be removed or become incapable
of acting as Administrative Trustee, at a time when an Event of Default with
respect to any Debt Security shall have occurred and be continuing, the Common
Securityholder by Act of the Common Securityholder delivered to the
Administrative Trustee shall promptly appoint a successor Administrative Trustee
or Administrative Trustees and such successor Administrative Trustee or Trustees
shall comply with the applicable requirements of Section 8.11. If no successor
Relevant Trustee shall have been so appointed by the Common Securityholder or
the Preferred 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 Property Trustee shall give notice of each resignation and each removal
of a Trustee and each appointment of a successor Trustee to all Securityholders
in the manner provided in Section 10.8 and shall give notice to the Sponsor.
Each notice shall include the name of the successor Relevant Trustee and the
address of its Corporate Trust Office if it is the Property Trustee.

     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, in the opinion of the Sponsor, incompetent or
incapacitated, the vacancy created by such death, incompetence or incapacity may
be filled by (a) the unanimous act of remaining Administrative Trustees if there
are at least two of them or (b) otherwise by the Sponsor (with the successor in
each case being a Person who satisfies the eligibility requirement for
Administrative Trustees or Delaware Trustee, as the case may be, set forth in
Section 8.7).

     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 Relevant Trustee with respect to
the Trust Securities shall execute and deliver an amendment hereto wherein each
successor Relevant Trustee shall accept such appointment and which (a) 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 with respect to the
Trust Securities and the Trust and (b) 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 Trust by more than one Relevant Trustee, it
being understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees 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,

                                       40

<PAGE>

on request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
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 Trust 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.

     Section 8.12. Merger, Conversion, Consolidation or Succession to Business.

     Any Person into which the Property Trustee or the Delaware Trustee may be
merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which 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, without the execution or filing of
any paper or any further act on the part of any of the parties hereto.

     Section 8.13. Preferential Collection of Claims Against Sponsor or Trust.

     If and when the Property Trustee or the Delaware Trustee shall be or become
a creditor of the Sponsor or the Trust (or any other obligor upon the Debt
Securities or the Trust Securities), the Property Trustee or the Delaware
Trustee, as the case may be, shall be subject to and shall take all actions
necessary in order to comply with the provisions of the Trust Indenture Act
regarding the collection of claims against the Sponsor or Trust (or any such
other obligor).

     Section 8.14. Reports by the 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. If required by Section 313(a) of the Trust
Indenture Act, the Property Trustee shall, within sixty days after each [ ]
following the date of this Trust Agreement deliver to Securityholders a brief
report, dated as of such [ ], which complies with the provisions of such Section
313(a).

     (b) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with each national stock exchange, the
Nasdaq National Market or such other interdealer quotation system or
self-regulatory organization upon which the Trust Securities are listed or
traded, with the Commission and with the Sponsor.

     Section 8.15. Reports to the Property Trustee.

     The Sponsor and the Administrative Trustees on behalf of the Trust shall
provide to the Property Trustee such documents, opinions, reports and
information as required by Section 314 of the Trust Indenture Act (if any) and
the compliance certificate required by Section 314(a) of the Trust Indenture Act
in the form, in the manner and at the times required by Section 314 of the Trust
Indenture Act.

     Section 8.16. Evidence of Compliance with Conditions Precedent.

     Each of the Sponsor 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 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 shall be given in the form of an
Officers' Certificate. Any certificate or opinion with respect to compliance
with a condition or covenant provided for herein shall comply with Section
314(e) of the Trust Indenture Act.

     Section 8.17. Number of Trustees.

     (a) The number of Trustees shall be four, provided that the Holder of all
of the Common Securities by written instrument may increase or decrease the
number of Administrative Trustees. The Property Trustee and the Delaware Trustee
may be the same Person, subject to the applicable eligibility requirements set
forth herein.

     (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

     (b) The Administrative Trustees shall have power to delegate from time to
time to such of their number or to the Sponsor the doing of such things and the

certificates are so surrendered, no payments of interest or principal will be
made to Holders of Trust Securities Certificates with respect to such Debt
Securities) and (v) all rights of Securityholders holding Trust Securities will
cease, except the right of such Securityholders to receive Debt Securities upon
surrender of Trust Securities Certificates.

     (d) In the event that, notwithstanding the other provisions of this Section
9.4, whether because of an order for dissolution entered by a court of competent
jurisdiction or otherwise, distribution of the Debt Securities in the manner

                                       44

<PAGE>

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 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 the Common Securities will be entitled to receive Liquidation Distributions
upon any such winding-up pro rata (determined as aforesaid) with Holders of
Preferred Securities, except that, if an Event of Default with respect to any
Debt Security has occurred and is continuing, the Preferred Securities shall
have a priority over the Common Securities.

     Section 9.5. Mergers, Consolidations, Amalgamations or Replacements of the
Trust.

     The Trust may not merge with or into, consolidate, convert into,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, except pursuant to this
Section 9.5 or Section 9.4. At the request of the Sponsor, with the consent of
the Administrative Trustees and without the consent of the Holders of the
Preferred Securities, the Property Trustee or the Delaware Trustee, the Trust
may merge with or into, consolidate, convert into, amalgamate, or be replaced by
or convey, transfer or lease its properties and assets substantially as an
entirety to a trust organized as such under the laws of any State; provided,
that (i) such successor entity either (a) expressly assumes all of the
obligations of the Trust with respect to the Preferred Securities or (b)
substitutes for the Preferred Securities other securities having substantially
the same terms as the Preferred Securities (the "Successor Securities") so long
as the Successor Securities rank the same as the Preferred Securities rank in
priority with respect to distributions and payments upon liquidation, redemption
and otherwise, (ii) the Sponsor expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Debt Securities, (iii) the Successor Securities are listed or
traded, or any Successor Securities will be listed upon notification of
issuance, on any national securities exchange or other organization on which the
Preferred Securities are then listed or traded, if any, (iv) such merger,
consolidation, conversion, amalgamation, replacement, conveyance, transfer or
lease does not cause the Preferred Securities (including any Successor
Securities) to be downgraded by any nationally recognized statistical rating
organization, (v) such merger, consolidation, conversion, amalgamation,
replacement, conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Preferred Securities (including
any Successor Securities) in any material respect, (vi) such successor entity
has a purpose substantially identical to that of the Trust, (vii) prior to such
merger, consolidation, conversion, amalgamation, replacement, conveyance,
transfer or lease, the Sponsor has received an Opinion of Counsel to the effect
that (a) such merger, consolidation, conversion, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences

                                       45

<PAGE>

and privileges of the holders of the Preferred Securities (including any
Successor Securities) in any material respect, and (b) following such merger,
consolidation, conversion, amalgamation, replacement, conveyance, transfer or
lease, neither the Trust nor such successor entity will be required to register
as an investment company under the 1940 Act and (viii) the Sponsor or any
permitted successor or assignee owns all of the common securities of such
successor entity and guarantees the obligations of such successor entity under
the Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
Holders of 100% in Liquidation Amount of the Preferred Securities, consolidate,
amalgamate, merge with or into, convert into or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to any
other Person or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, conversion, amalgamation, merger,
replacement, conveyance, transfer or lease would cause the Trust or the
successor entity to be classified as other than a grantor trust for United
States Federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

     Section 10.1. Limitation of Rights of Securityholders.

     The death, incapacity, dissolution, bankruptcy or termination of any Person
having an interest, beneficial or otherwise, in Trust Securities 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

ambiguity, correct or supplement any provision herein which may be inconsistent
with any other provision herein, or to make any other provisions with respect to
matters or questions arising under this Trust Agreement, which shall not be
inconsistent with the other provisions of this Trust Agreement, or (ii) 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 be classified for
United States Federal income tax purposes as a grantor trust at all times that
any Trust Securities are outstanding or to ensure that the Trust will not be
required to register as an investment company under the 1940 Act; provided,
however, that in the case of clause (i), such action shall not adversely affect
in any material respect the interests of any Securityholder, and any such
amendments of this Trust Agreement shall become effective when notice thereof is
given to the Securityholders.

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

of an investment company under the 1940 Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder, this Trust

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; notwithstanding
any other provision herein, without the unanimous consent of the
Securityholders, this paragraph (c) of this Section 10.2 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an investment company under the 1940 Act or fail or cease to be
classified as a grantor trust for United States Federal income tax purposes.

     (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Sponsor, this Trust Agreement may not be amended in a
manner which imposes any additional obligation on the Sponsor.

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

     (g) Neither the Property Trustee nor the Delaware Trustee shall be required
to enter into any amendment to this Trust Agreement which affects its own
rights, duties or immunities under this Trust Agreement. The Property Trustee
and Delaware Trustee shall be entitled to receive an Opinion of Counsel and an
Officers' Certificate stating that any amendment to this Trust Agreement is in
compliance with this Trust Agreement.

     Section 10.3. Separability.

     Section 10.9. Agreement Not to Petition.

     Each of the Trustees and the Sponsor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Sponsor takes action in violation of this Section 10.9, the
Property Trustee agrees, for the benefit of Securityholders, that at the expense
of the Sponsor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Sponsor against the Trust or
the commencement of such action and raise the defense that the Sponsor has
agreed in writing not to take such action and should be stopped and precluded
therefrom and such other defenses, if any, as counsel for the Trustee or the
Trust may assert. The provisions of this Section 10.9 shall survive the
termination of this Trust Agreement.

control. If any provision of this Trust Agreement modifies or excludes any
provision of the Trust Indenture Act which may be so modified or excluded, the
latter provision shall be deemed to apply to this Trust Agreement as so modified
or excluded, as the case may be.

     (d) The application of the Trust Indenture Act to this Trust Agreement

                  General Counsel's Office

                           Re:

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the [TITLE OF
PREFERRED SECURITIES] (the "Preferred Securities"), of Covanta Capital Trust [
], a Delaware business trust (the "Issuer"), formed pursuant to a Trust
Agreement between Covanta Energy Corporation (the "Company") and BANKERS TRUST
COMPANY, as Property Trustee, WILMINGTON TRUST COMPANY, as Delaware Trustee, and
the Administrative Trustees named therein. The payment of distributions on the
Preferred Securities, and payments due upon liquidation of Issuer or redemption
of the Preferred Securities, to the extent the Issuer has funds available for
the payment thereof are guaranteed by the Company to the extent set forth in a
Guarantee Agreement dated --------, ---- by the Company with respect to the
Preferred Securities. The Company and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement dated --------, 2001 by and among the Underwriters, the
Issuer and the Company, and the Underwriters wish to take delivery of the
Preferred Securities through DTC. [ ] is acting as transfer agent and registrar
with respect to the Preferred Securities (then "Transfer Agent and Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:

     1. Prior to the closing of the sale of the Preferred Securities to the
Underwriters, which is expected to occur on or about --------, ----, there shall
be deposited with or on behalf of DTC one or more global certificates
(individually and collectively, the "Global Certificate") registered in the name
of DTC's Preferred Securities nominee, Cede & Co., representing an aggregate of
Preferred Securities and bearing the following legend:

     Unless this certificate is presented by an authorized representative of The
Depository Trust Company, a New York corporation ("DTC"), to Issuer or its agent
for registration of transfer, exchange, or payment, and any certificate issued
is registered in the name of Cede & Co. or in such other name as is requested by
an authorized representative of DTC (and any payment is made to Cede & Co. or to
such other entity as is requested by an authorized representative of DTC), ANY

                                      B-1

<PAGE>

TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest
herein.

     2. The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances. The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

     3. In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4. In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.
Notices to DTC's Dividend Department by telecopy shall be sent to (212)
709-1723. Such notices by mail or by any other means shall be sent to:

                  Manager, Announcements
                  Dividend Department

                  New York, New York 10004-2695

     The Issuer or the Transfer Agent and Registrar shall confirm DTC's receipt
of such telecopy by telephoning the Dividend Department at (212) 709-1270.

     5. In the event of a redemption by the Issuer of the Preferred Securities,
notice specifying the terms of the redemption and the Publication Date of such
notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC

                                      B-2

<PAGE>

not less than 30 calendar days prior to such event by a secure means in the
manner set forth in paragraph 4. Such redemption notice shall be sent to DTC's
Call Notification Department at (516) 227-4164 or (516) 227-4190, and receipt of
such notice shall be confirmed by telephoning (516) 227-4070. Notice by mail or
by any other means shall be sent to:

                  Garden City, New York 11530-4719

     6. In the event of any invitation to tender the Preferred Securities,
notice specifying the terms of the tender and the Publication Date of such
notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC by
a secure means and in a timely manner as described in paragraph 4. Notices to
DTC pursuant to this paragraph and notices of other corporate actions (including
mandatory tenders, exchanges and capital changes) shall be sent, unless
notification to another department is expressly provided for herein, by telecopy
to DTC's Reorganization Department at (212) 709-1093 or (212) 709-1094 and
receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by
mail or any other means to:

                  7 Hanover Square, 23rd Floor
                  New York, New York 10004-2695

     7. All notices and payment advices sent to DTC shall contain the CUSIP
number or numbers of the Preferred Securities and the accompanying designation
of the Preferred Securities, which, as of the date of this letter, is "[TITLE OF
PREFERRED SECURITIES]."

     8. Distribution payments or other cash payments with respect to the
Preferred Securities evidenced by the Global Certificate shall be received by
Cede & Co., as nominee of DTC, or its registered assigns in [ ] funds on each
payment date (or in accordance with existing arrangements between the Issuer or
the Transfer Agent and Registrar and DTC). Such payments shall be made payable
to the order of Cede & Co., and shall be addressed as follows:

                  New York, New York 10004-2695

     9. DTC may by prior written notice direct the Issuer and the Transfer Agent
and Registrar to use any other telecopy number or address of DTC as the number

     10. In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
Transfer Agent and Registrar's invitation) necessitating a reduction in the

aggregate number of Preferred Securities outstanding evidenced by Global
Certificates, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

     11. DTC may discontinue its services as a securities Depository with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law. Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar, and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any
other documents of transfer reasonably requested by the Issuer or the Transfer
Agent and Registrar.

     12. In the event that the Issuer determines that beneficial owners of
Preferred Securities shall be able to obtain definitive Preferred Securities,
the Issuer or the Transfer Agent and Registrar shall notify DTC of the
availability of certificates. In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     13. This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument. Nothing
herein shall be deemed to require the Transfer Agent and Registrar to advance
funds on behalf of Covanta Capital Trust [ ].

                                 Very truly yours,

Guarantee Agreement to any Person except a Holder exercising his or her rights
pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on acceptance by
such Successor Guarantee Trustee of its appointment to act as Successor
Guarantee Trustee. The right, title and interest of the Guarantee Trustee shall

occurred (that has not been cured or waived pursuant to Section 2.6), the

exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

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

               (A) the duties and obligations of the Guarantee Trustee shall be
          determined solely by the express provisions of this Guarantee
          Agreement, and the Guarantee Trustee shall not be liable except for
          the performance of such duties and obligations as are specifically set
          forth in this Guarantee Agreement; and

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

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

                                       6

<PAGE>

          (iii) the Guarantee Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of not less than a majority in Liquidation
     Amount of the Preferred Securities relating to the time, method and place
     of conducting any proceeding for any remedy available to the Guarantee
     Trustee, or exercising any trust or power conferred upon the Guarantee
     Trustee under this Guarantee Agreement; and

          (iv) no provision of this Guarantee Agreement shall require the
     Guarantee 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 Guarantee Trustee shall
     have reasonable grounds for believing that the repayment of such funds or
     liability is not assured to it under the terms of this Guarantee Agreement
     or indemnity satisfactory to it against such risk or liability is not
     assured to it.

     specifically prescribed) may, in the absence of bad faith on its part,
     request and conclusively rely upon an Officers' Certificate.

          (iv) The Guarantee Trustee may consult with legal counsel, and the
     advice or opinion of such legal counsel with respect to legal matters shall

     accordance with such advice or opinion. Such legal counsel may be legal
     counsel to the Guarantor or any of its Affiliates and may be one of its

     instructions concerning the administration of this Guarantee Agreement from
     any court of competent jurisdiction.

          (v) The Guarantee Trustee shall be under no obligation to exercise any
     of the rights or powers vested in it by this Guarantee Agreement at the

     against the costs, expenses (including attorneys' fees and expenses) and
     liabilities that might be incurred by it in complying with such request or

                                       7

<PAGE>

     direction, including such reasonable advances as may be requested by the
     Guarantee Trustee; provided that, nothing contained in this Section
     3.2(a)(v) shall be taken to relieve the Guarantee Trustee, upon the
     occurrence of an Event of Default, of its obligation to exercise the rights
     and powers vested in it by this Guarantee Agreement.

          (vi) The Guarantee Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,

     direction, consent, order, bond, debenture, note, other evidence of
     indebtedness or other paper or document, but the Guarantee Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit.

     hereunder or perform any duties hereunder either directly or by or through
     its agents or attorneys, and the Guarantee Trustee shall not be responsible
     for any misconduct or negligence on the part of any such agent or attorney
     appointed with due care by it hereunder.

          (viii) Whenever in the administration of this Guarantee Agreement the
     Guarantee Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder, the Guarantee Trustee (A) may request and shall be entitled to
     receive instructions from the Holders, (B) may refrain from enforcing such
     remedy or right or taking such other action until such instructions are

jurisdiction in which it shall be illegal, or in which the Guarantee 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. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee in respect of this Guarantee Agreement or exercising any
trust or power conferred upon the Guarantee Trustee under this Guarantee
Agreement; and (iv) if the Guarantee Trustee fails to enforce this Guarantee
Agreement, any Holder may institute a legal proceeding directly against the
Guarantor to enforce its rights under this Guarantee Agreement, without first
instituting a legal proceeding against the Issuer or any other Person. If the
