have any duty or obligation hereunder or with respect to the trust estate,
except as otherwise required by applicable law or as may be necessary to obtain
prior to such execution and delivery any licenses, consents or approvals
required by applicable law or otherwise.

     SECTION 4. CERTAIN AUTHORIZATIONS. The Depositor and the Trustee hereby
authorize and direct the Depositor, as the sponsor of the Trust, (i) to file
with the Securities and Exchange Commission (the "COMMISSION") and execute, in
each case on behalf of the Trust, (a) the Registration Statement on Form S-3
(the "1933 ACT REGISTRATION STATEMENT"), including any pre-effective or
post-effective amendments to such 1933 Act Registration Statement (including the
prospectus and exhibits contained therein), relating to the registration under
the Securities Act of 1933, as amended, of the preferred securities of the Trust
(the "PREFERRED SECURITIES") and certain other securities of the Depositor and

post-effective amendments thereto) relating to the registration of the Preferred

and to execute on behalf of the Trust any and all of the foregoing.

     SECTION 5. COUNTERPARTS. This Trust Agreement may be executed in one or
more counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument.

     SECTION 6. TRUSTEE. The number of Trustees initially shall be one and
thereafter the number of Trustees shall be such number as shall be fixed from
time to time by a written instrument signed by the Depositor, which may increase
or decrease the number of Trustees; PROVIDED, HOWEVER, that to the extent
required by the Business Trust Act, one Trustee shall be either a natural person
who is a resident of the State of Delaware or, if not a natural person, an
entity which has its principal place of business in the State of Delaware and
otherwise meets the requirements of applicable Delaware law. Subject to the
foregoing, the Depositor is entitled to appoint or remove without cause any
Trustee at any time. The Trustee may resign upon thirty days' prior notice to

     Trust, as the Depositor deems necessary or advisable in order to comply
     with the applicable laws of any such states;

          (iii)   the preparation for filing by the Trust and execution on

     carry out any of the foregoing activities.

     (d)  Notwithstanding anything herein to the contrary, the Administrative
Trustees are authorized and directed to conduct the affairs of the Trust and to
operate the Trust so that the Trust shall not be deemed to be an "investment
company" required to be registered under the Investment Company Act, shall be
classified as a "grantor trust" and not as an association taxable as a
corporation for United States federal income tax purposes and so that the
Debentures shall be treated as indebtedness of the Depositor for United States
federal income tax purposes. In this connection, subject to Section 1002, the
Depositor and the Administrative Trustees are authorized to take any action and
the Administrative Trustees are authorized to direct the Property Trustee in
writing to take any action, not inconsistent with applicable law or this Trust
Agreement, that each of the Depositor and the Administrative Trustees determines
in their discretion to be necessary or desirable for such purposes but in no
event shall the Depositor, Administrative Trustee, or Property Trustee have the
power to take any action, permit any action to be taken, or refrain to act in
such a manner, that could cause the Trust to not be treated as a grantor trust
for federal income tax purposes. The Property Trustee shall take any action so
directed by one or more of the Administrative Trustees.

   SECTION 208.  ASSETS OF TRUST. The assets of the Trust shall consist of the
Trust Property.

Agreement. All monies and other property deposited or held from time to time in

herein.

     (b)  The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest on, and any other

                            DISTRIBUTIONS; REDEMPTION

   SECTION 401.  DISTRIBUTIONS. (a) Distributions on the Trust Securities shall
be cumulative, and shall accumulate whether or not there are funds of the Trust
available for the payment of Distributions. Distributions shall accumulate from
the date of issuance of the Trust Securities, and, except during any Extended
Interest Period with respect to the Debentures, shall be payable quarterly in
arrears on March 31, June 30, September 30 and December 31 of each year,
commencing on ____________, 2003. 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 Business Day is in the next succeeding calendar year,
such payment shall be made on the immediately preceding Business Day (and
without any reduction in interest or any other payment in respect of any such
acceleration), 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 401(a), a "DISTRIBUTION DATE").

     (b)  The Trust Securities represent undivided beneficial interests in the
Trust Property. Distributions on the Trust Securities shall be payable at a rate
of _____% per annum of the Liquidation Amount of the Trust Securities. 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 for
any partial period shall be computed on the basis of the number of days elapsed
in a 360-day year of twelve 30-day months. During any Extended Interest Period
with respect to the Debentures, Distributions on the Preferred Securities shall
be deferred for a period equal to the Extended Interest Period. The amount of
Distributions payable for any period shall include the Additional Amounts, if
any.

     (c)  Distributions on the Trust Securities shall be made by the Property
Trustee solely 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
immediately available by 12:30 p.m. on each Distribution Date 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
the 15th day of March, June, September or December for Distributions payable on
the last calendar day of the respective month; PROVIDED, HOWEVER, that for any
Trust Securities held in global form, Distributions shall be payable to the
Holder thereof as of one Business Day immediately preceding the Distribution
Date.

   SECTION 402.  REDEMPTION. (a) Only on each Debenture Redemption Date and at
maturity of the Debentures shall the Trust be required to redeem a Like Amount
of Trust Securities at the Redemption Price.

                                      -17-
<Page>

     (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 Securities Register. The Property
Trustee shall have no responsibility for the accuracy of any CUSIP number
contained in such notice. All notices of redemption shall state:

            (i)   the Redemption Date;

           (ii)   the Redemption Price;

          (iii)   the CUSIP number;

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

            (v)   that, on the Redemption Date, the Redemption Price shall
     become due and payable upon each such Trust Security to be redeemed and
     that Distributions thereon shall cease to accumulate on and after said
     date, except as provided in Section 402(d); and

           (vi)   the place or places at which Trust Securities are to be
     surrendered for the payment of the Redemption Price.

     (c)  The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of the Debentures. 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 immediately available 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
Preferred Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 402(c), the Property Trustee, subject to Section
402(c), shall, with respect to Preferred Securities held in global form, deposit
with the Clearing Agency for such Preferred Securities, to the extent available
therefor, 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 of the Preferred Securities. With respect to
Trust Securities that are not held in global form, the Property Trustee, subject
to Section 402(c), shall deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price and shall give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof
upon surrender of their Preferred 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 Securities Register for the Trust
Securities on the relevant record dates for the related Distribution Dates. If
notice of redemption shall have been given and funds deposited as required, then
upon the date of such deposit, (i) all rights of Securityholders holding Trust
Securities so called for redemption shall

                                      -18-
<Page>

cease, except the right of such Securityholders to receive the Redemption Price,
but without interest, (ii) such Trust Securities shall cease to be Outstanding,
(iii) the Clearing Agency for the Preferred Securities or its nominee, as the
registered Holder of the Global Preferred Securities Certificate, shall receive
a registered global certificate or certificates representing the Debentures to
be delivered upon such distribution with respect to Preferred Securities held by
the Clearing Agency or its nominee, and (iv) any Trust Securities Certificates
not held by the Clearing Agency for the Preferred Securities or its nominee as
specified in clause (iii) above will be deemed to represent Debentures having a
principal amount equal to the stated Liquidation Amount of the Trust Securities
represented thereby and bearing accrued and unpaid interest in an amount equal
to the accumulated and unpaid Distributions on such Trust Securities until such
certificates are presented to the Securities Registrar for transfer or
reissuance. 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
shall be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day (and without any reduction of interest
or any other payment in respect of any such acceleration), in each case with the
same force and effect as if made on 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
Depositor pursuant to the Guarantee, Distributions on such Trust Securities
shall continue to accumulate, 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 paid, in which case the actual payment date
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 record holders thereof as they appear on the Securities Register for the
Trust Securities on the relevant record date, which shall be the date 15 days
prior to the relevant Redemption Date.

     (f)  Subject to Section 403(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated 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 (including, without limitation, by lot) as the
Property Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to such Liquidation Amount or an
integral multiple of such Liquidation Amount in excess thereof) of the
Liquidation Amount of the Preferred Securities of a denomination larger than
such Liquidation Amount; PROVIDED, HOWEVER, that in the event the redemption
relates only to Preferred Securities purchased and held by the Depositor being
redeemed in exchange for a Like Amount of Debentures, the Property Trustee shall
select those particular Preferred Securities for redemption. The Property
Trustee shall promptly notify the Securities 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 the

                                      -19-
<Page>

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 the Preferred Securities which has been or is to be redeemed.

   SECTION 403.  SUBORDINATION OF THE COMMON SECURITIES. (a) Payment of
Distributions (including Additional Amounts, if applicable) on, and the
Redemption Price of, the Trust Securities, as applicable, shall be made, subject
to Section 402(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 a Debenture Event of Default shall have occurred and be
continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of the
Common Securities, shall be made unless payment in full in cash of all
accumulated and unpaid Distributions (including Additional Amounts, if
applicable) on all Outstanding Preferred 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 then called for redemption, shall have been made or provided for, and
all funds immediately available to the Property Trustee shall first be applied
to the payment in full in cash of all Distributions (including Additional
Amounts, if applicable) on, or the Redemption Price of, the Preferred Securities
then due and payable.

     (b)  In the case of the occurrence of any Event of Default resulting from a
Debenture Event of Default, the Holder of the Common Securities shall 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 shall have been cured, waived or otherwise
eliminated. Until any such Event of Default under this Trust Agreement with
respect to the Preferred Securities shall have 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 shall have the right to direct
the Property Trustee to act on their behalf.

   SECTION 404.  PAYMENT PROCEDURES. Payments of Distributions (including
Additional Amounts, if applicable) 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 will credit the relevant accounts
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 405.  TAX RETURNS AND REPORTS. The Administrative Trustees shall
prepare (or cause to be prepared), at the Depositor'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 forms 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
                                      -20-
<Page>

furnished) to each Securityholder the appropriate Internal Revenue Service forms
required to be furnished to such Securityholder or the information required to
be provided on such forms. The Administrative Trustees shall provide the
Depositor with a copy of all such returns and reports promptly after such filing
or furnishing. The Property Trustee shall comply with United States federal
withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to the Securityholders under the Trust
Securities and the Securityholders shall provide any information required by the
Property Trustee in connection with such requirements.

   SECTION 406.  PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST. Upon receipt under
the Debentures of Additional Payments, the Property Trustee, at the direction of
an Administrative Trustee or the Depositor, shall promptly pay any taxes, duties
or governmental charges of whatsoever nature (other than withholding taxes)
imposed on the Trust by the United States or any other taxing authority.

   SECTION 407.  PAYMENTS UNDER THE INDENTURE. Any amount payable hereunder to
any Holder of Preferred Securities shall be reduced by the amount of any
corresponding payment such Holder has directly received under the Indenture
pursuant to Section 514(b) or (c) hereof.

Certificates shall be issued in minimum denominations of the Liquidation Amount
and integral multiples of such Liquidation Amount in excess thereof, and the
Common Securities Certificates shall be issued in denominations of the
Liquidation Amount and integral multiples thereof. The Trust Securities
Certificates shall be executed on behalf of the Trust by manual or facsimile
signature of at least one Administrative Trustee. The Trust Securities
Certificates bearing the manual or facsimile 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 504, 511
and 514.

   SECTION 503.  EXECUTION, AUTHENTICATION AND DELIVERY OF THE TRUST SECURITIES
CERTIFICATES. (a) On the Closing Date and, if applicable, the Option Closing
Date, as such term is defined in

                                      -21-
<Page>

the Underwriting Agreement, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 204 and 205, to be executed on behalf of the Trust by the manual or
facsimile signature of at least one of the Administrative Trustees and delivered
to or upon the written order of the Depositor, signed by its Chief Executive
Officer, President, any Senior Vice President, the Treasurer or any Assistant
Treasurer without further corporate action by the Depositor, in authorized
denominations.

     (b)  A Preferred Securities Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the Property
Trustee in substantially the form of Exhibit E hereto. The signature shall be
conclusive evidence that the Preferred Securities Certificate has been
authenticated under this Trust Agreement. Each Preferred Security Certificate
shall be dated the date of its authentication.

     (c)  Upon the written order of the Trust signed by one of the
Administrative Trustees, the Property Trustee shall authenticate and make
available for delivery the Preferred Securities Certificates.

     (d)  The Property Trustee may appoint an Authenticating Agent acceptable to
the Trust to authenticate the Preferred Securities. An Authenticating Agent may
authenticate the Preferred Securities whenever the Property Trustee may do so.
Each reference in this Trust Agreement to authentication by the Property Trustee
includes authentication by such agent. An Authenticating Agent has the same
rights as the Property Trustee to deal with the Depositor or the Trust.

   SECTION 503A.  GLOBAL PREFERRED SECURITY. (a) Any Global Preferred Security
issued under this Trust Agreement shall be registered in the name of the nominee
of the Clearing Agency and delivered to such custodian therefor, and such Global
Preferred Security shall constitute a single Preferred Security for all purposes
of this Trust Agreement.

     (b)  Notwithstanding any other provision in this Trust Agreement, no Global
Preferred Security may be exchanged for Preferred Securities registered in the
names of persons other than the Depositary or its nominee unless (i) the
Depositary notifies the Administrative Trustees and Property Trustee in writing
that it is unwilling or unable to continue as a depositary for such Global
Preferred Securities and the Depositor is unable to locate a qualified successor
depositary, (ii) the Depositor executes and delivers to the Administrative
Trustees and Property Trustee a written order stating that it elects to
terminate the book-entry system through the Depositary or (iii) there shall have
occurred and be continuing a Debenture Event of Default.

     (c)  If a Preferred Security is to be exchanged in whole or in part for a
beneficial interest in a Global Preferred Security, then either (i) such Global
Preferred Security shall be so surrendered for exchange or cancellation as
provided in this Article V or (ii) the Liquidation Amount thereof shall be
reduced or increased by an amount equal to the portion thereof to be so
exchanged or cancelled, or equal to the Liquidation Amount of such other
Preferred Securities to be so exchanged for a beneficial interest therein, as
the case may be, by means of an appropriate adjustment made on the records of
the Securities Registrar, whereupon the Property Trustee, in accordance with the
rules and procedures of the Depositary for such Global Preferred Security (the
"APPLICABLE PROCEDURES"), shall instruct the Clearing Agency or its authorized

                                      -22-
<Page>

representative to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global Preferred Security by the Clearing Agency,
accompanied by registration instructions, the Administrative Trustees shall
execute and the Property Trustee shall, subject to Section 504(b) and as
otherwise provided in this Article V, authenticate and deliver any Preferred
Securities issuable in exchange for such Global Preferred Security (or any
portion thereof) in accordance with the instructions of the Clearing Agency. The
Property Trustee shall not be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be fully protected in
relying on, such instructions.

     (d)  Every Preferred Security executed, authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global
Preferred Security or any portion thereof, whether pursuant to this Article V or
otherwise, shall be executed, authenticated and delivered in the form of, and
shall be, a Global Preferred Security, unless such Global Preferred Security is
registered in the name of a Person other than the Clearing Agency for such
Global Preferred Security or a nominee thereof.

     (e)  The Clearing Agency or its nominee, as the registered owner of a
Global Preferred Security, shall be considered the Holder of the Preferred
Securities represented by such Global Preferred Security for all purposes under
this Trust Agreement and the Preferred Securities, and owners of beneficial
interests in such Global Preferred Security shall hold such interests pursuant
to the Applicable Procedures and, except as otherwise provided herein, shall not
be entitled to receive physical delivery of any such Preferred Securities in
definitive form and shall not be considered the Holders thereof under this Trust
Agreement. Accordingly, any such owner's beneficial interest in the Global
Preferred Securities shall be shown only on, and the transfer of such interest
shall be effected only through, records maintained by the Clearing Agency or its
nominee. Neither the Property Trustee, the Securities Registrar nor the
Depositor shall have any liability in respect of any transfers effected by the
Clearing Agency.

     (f)  The rights of owners of beneficial interests in a Global Preferred
Security 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.

   SECTION 504.  REGISTRATION OF TRANSFER AND EXCHANGE OF THE PREFERRED
SECURITIES CERTIFICATES. (a) The Depositor shall keep or cause to be kept, at
the office or agency maintained pursuant to Section 508, a register or registers
for the purpose of registering the Trust Securities Certificates and, subject to
the provisions of Section 503A, transfers and exchanges of the Preferred
Securities Certificates (herein referred to as the "SECURITIES REGISTER") in
which the registrar designated by the Depositor (the "SECURITIES REGISTRAR"),
subject to such reasonable regulations as it may prescribe, shall provide for
the registration of the Preferred Securities Certificates and the Common
Securities Certificates (subject to Section 510 in the case of the Common
Securities Certificates) and registration of transfers and exchanges of the
Preferred Securities Certificates as herein provided. The Property Trustee shall
be the initial Securities Registrar.

     (b)  Subject to the provisions of Section 503A, only upon surrender for
registration of transfer of any Preferred Securities Certificate at the office
or agency maintained pursuant to

                                      -23-
<Page>

Section 508 shall the Administrative Trustees or any one of them 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 the manual or
facsimile signature of such Administrative Trustee or Trustees. The Securities
Registrar shall not be required to register the transfer of any of the Preferred
Securities that have been called for redemption. At the option of a Holder, the
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 508.

     (c)  Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange, subject to the provisions of Section 503A,
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 canceled and
subsequently disposed of by the Property Trustee in accordance with its
customary practice. The Trust shall not be required to (i) issue, register the
transfer of, or exchange any of the Preferred Securities during a period
beginning at the opening of business 15 calendar days before the date of mailing
of a notice of redemption of any of the Preferred Securities called for
redemption and ending at the close of business on the day of such mailing; or
(ii) register the transfer of or exchange any of the Preferred Securities so
selected for redemption, in whole or in part, except the unredeemed portion of
any such Preferred Securities being redeemed in part.

     (d)  No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, subject to the provisions of
Section 503A, 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 the Preferred Securities
Certificates.

     (e)  Preferred Securities may only be transferred, in whole or in part, in
accordance with the terms and conditions set forth in this Trust Agreement. Any
transfer or purported transfer of any Preferred Security not made in accordance
with this Trust Agreement shall be null and void. A Preferred Security that is
not a Global Preferred Security may be transferred, in whole or in part, to a
Person who takes delivery in the form of another Preferred Security that is not
a Global Preferred Security as provided in Section 504(a). A beneficial interest
in a Global Preferred Security may be exchanged for a Preferred Security that is
not a Global Preferred Security only as provided in Section 503A.

   SECTION 505.  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, the Property Trustee 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

                                      -24-
<Page>

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 505, 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 505 shall constitute conclusive evidence of an undivided beneficial
interest in the assets of the Trust, as if originally issued, whether or not the
lost, stolen or destroyed Trust Securities Certificate shall be found at any
time.

   SECTION 506.  PERSONS DEEMED THE SECURITYHOLDERS. The Trustees, the Paying
Agent and 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 507.  ACCESS TO LIST OF THE SECURITYHOLDERS' NAMES AND ADDRESSES. At
any time when the Property Trustee is not also acting as the Securities
Registrar, the Administrative Trustees or the Depositor shall furnish or cause
to be furnished to the Property Trustee (a) within five Business Days of
March 15, June 15, September 15 and December 15 in each year, 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; and (b) promptly after
receipt by any Administrative Trustee or the Depositor of a request therefor
from the Property Trustee in order to enable the Property Trustee to discharge
its obligations under this Trust Agreement, in each case to the extent such
information is in the possession or control of the Administrative Trustees or
the Depositor and is not identical to a previously supplied list or has not
otherwise been received by the Property Trustee in its capacity as Securities
Registrar. The rights of the Securityholders to communicate with other
Securityholders with respect to their rights under this Trust Agreement or under
the Trust Securities, and the corresponding rights of the Trustee shall be as
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 Depositor, 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 508.  MAINTENANCE OF OFFICE OR AGENCY. The Administrative Trustees
shall maintain in a location or locations designated by the Administrative
Trustees, an office or offices or agency or agencies where the 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 Corporate Trust Office of the Property Trustee,
Wilmington Trust Company, as the principal corporate trust office for such
purposes. The Administrative Trustees shall give prompt written notice to the
Depositor and to the Securityholders of any change in the location of the
Securities Register or any such office or agency.

   SECTION 509.  APPOINTMENT OF THE PAYING AGENT. The Paying Agent shall
initially be the Property Trustee, and any co-paying agent chosen by the
Property Trustee must be acceptable to

                                      -25-
<Page>

the Administrative Trustees and the Depositor. The Paying Agent shall make
Distributions to the 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 obligations under this Trust Agreement in any
material respect. 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 Depositor. In the event that the Property Trustee 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 (which shall be a bank or trust company) that is acceptable to the
Property Trustee and the Depositor to act as the Paying Agent. 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 shall 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 801, 803 and 806 shall apply to the Property Trustee also in its
role as the Paying Agent, for so long as the Property Trustee shall act as
Paying Agent and, to the extent applicable, to any other Paying Agent appointed
hereunder. Any reference in this Trust Agreement to the Paying Agent shall
include any co-paying agent unless the context requires otherwise.

   SECTION 510.  OWNERSHIP OF THE COMMON SECURITIES BY THE DEPOSITOR. On the
Closing Date, the Depositor shall acquire and retain beneficial and record
ownership of the Common Securities. To the fullest extent permitted by law, any
attempted transfer of the Common Securities (other than a transfer in connection
with a merger or consolidation of the Depositor into another corporation
pursuant to Section 12.1 of the Indenture) shall be void. The Administrative
Trustees shall cause each Common Securities Certificate issued to the Depositor
to contain a legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE."

   SECTION 511.  THE TRUST SECURITIES CERTIFICATES. (a) The Preferred Securities
Certificates shall be issued in the form of one or more fully registered Global
Preferred Securities Certificates which will be deposited with or on behalf of
the Clearing Agency and registered in the name of the Clearing Agency's nominee.
Unless and until it is exchangeable in whole or in part for the Preferred
Securities in definitive form, a global security may not be transferred except
as a whole by the Clearing Agency to a nominee of the Clearing Agency or by a
nominee of the Clearing Agency to the Clearing Agency or another nominee of the
Clearing Agency or by the Clearing Agency or any such nominee to a successor of
such Clearing Agency or a nominee of such successor.

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

                                      -26-

   SECTION 512.  [RESERVED].

   SECTION 513.  NOTICES. To the extent that a notice or other communication to
the Holders is required under this Trust Agreement, for so long as Preferred
Securities are represented by a Global Preferred Securities Certificate, the
Trustees shall give all such notices and communications specified herein to be
given to the Clearing Agency, and shall have no obligation to provide notice to
the owners of the beneficial interest in the Global Preferred Securities.

   SECTION 514.  RIGHTS OF THE 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 209, and the Securityholders shall not have any right
or title therein other than the undivided beneficial interest in the assets of
the Trust conferred by their Trust Securities and they shall have no right to
call for any partition or division of property, profits or rights of the Trust
except as described below. The Trust Securities shall be personal property
giving only the rights specifically set forth therein and in this Trust
Agreement. The Trust Securities shall have no preemptive or similar rights. When
issued and delivered to Holders of the Preferred Securities against payment of
the purchase price therefor, the Preferred Securities shall be fully paid and
nonassessable interests in the Trust. The Holders of the Preferred 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 of the Preferred Securities remain Outstanding, if,
upon a Debenture Event of Default, the Debenture Trustee fails or the holders of
not less than 25% in principal amount of the outstanding Debentures fail to
declare the principal of all of the Debentures to be immediately due and
payable, the Holders of at least 25% in Liquidation Amount of the Preferred
Securities then Outstanding shall have such right by a notice in writing to the
Depositor and the Debenture Trustee; and upon any such declaration such
principal amount of and the accrued interest on all of the Debentures shall
become immediately due and payable, PROVIDED that the payment of principal and
interest on such Debentures shall remain subordinated to the extent provided in
the Indenture.

     (c)  For so long as any of the Preferred Securities remain Outstanding,
upon a Debenture Event of Default arising from the failure to pay interest or
principal on the Debentures, the Holders of any of the Preferred Securities then
Outstanding shall, to the fullest extent permitted by law, have the right to
directly institute proceedings for enforcement of payment to such Holders of
principal of or interest on the Debentures having a principal amount equal to
the Liquidation Amount of the Preferred Securities of such Holders.

                  ACTS OF THE SECURITYHOLDERS; MEETINGS; VOTING

   SECTION 601.  LIMITATIONS ON VOTING RIGHTS. (a) Except as provided in this
Section 601, in Sections 514, 810 and 1002 and in the Indenture and as otherwise
set forth in the Guarantee or 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
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 Debentures are held by the Property Trustee, on behalf
of the Trust, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on the Debenture Trustee with respect to
such Debentures; (ii) waive any past default which is waivable under Article VII
of the Indenture; (iii) exercise any right to rescind or annul a declaration
that the principal of all the Debentures shall be due and payable; or (iv)
consent to any amendment, modification or termination of the Indenture or the
Debentures, 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 the Outstanding Trust Securities; PROVIDED, HOWEVER,
that where a consent under the Indenture would require the consent of each
holder of outstanding Debentures affected thereby, no such consent shall be
given by the Property Trustee without the prior written consent of each Holder
of the Trust Securities. The Trustees shall not revoke any action previously
authorized or approved by a vote of the Holders of the Outstanding Trust
Securities, except when authorized by a subsequent vote of the Holders of the
Outstanding Trust Securities. The Property Trustee shall notify each Holder of
the Outstanding Preferred Securities of any notice of default received from the
Debenture Trustee with respect to the Debentures. In addition to obtaining the
foregoing approvals of the Holders of the Trust Securities, prior to taking any
of the foregoing actions, the Trustees shall, at the expense of the Depositor,
obtain an Opinion of Counsel experienced in such matters to the effect that the
Trust shall continue to be classified as a grantor trust and not as an
association taxable as a corporation for United States federal income tax
purposes on account of such action.

     (c)  If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the Holders
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
the Outstanding Preferred Securities as a class shall 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. No amendment to this Trust
Agreement may be made if, as a result of such amendment, the Trust would cease
to be classified as a grantor trust or would be classified as an association
taxable as a corporation for United States federal income tax purposes.

                                      -28-

   SECTION 602.  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 1008 to each Preferred
Securityholder of record, at his or her registered address, at least 15 days and
not more than 90 days before the meeting. At any such meeting, any business
properly before the meeting may be so considered whether or not stated in the
notice of the meeting. Any adjourned meeting may be held as adjourned without
further notice.

   SECTION 603.  MEETINGS OF THE PREFERRED SECURITYHOLDERS. (a) No annual
meeting of the Securityholders is required to be held. The Administrative
Trustees, however, shall call a meeting of the Securityholders to vote on any
matter in respect of which the Preferred Securityholders are entitled to vote
upon the written request of the Preferred Securityholders of 25% of the
Outstanding Preferred Securities (based upon their aggregate Liquidation Amount)
and the Administrative Trustees or the Property Trustee may, at any time in
their discretion, call a meeting of the Preferred Securityholders to vote on any
matters as to which the Preferred Securityholders are entitled to vote.

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

     (c)  If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding more
than a majority of the Preferred Securities (based upon their aggregate
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 604.  VOTING RIGHTS. The Securityholders shall be entitled to one
vote for each dollar value of Liquidation Amount represented by their Trust
Securities (with any fractional multiple thereof rounded up or down as the case
may be to the closest integral multiple) in respect of any matter as to which
such Securityholders are entitled to vote (and such dollar value shall be $10
per Preferred Security until such time, if any, as the Liquidation Amount is
changed as provided herein).

   SECTION 605.  PROXIES, ETC. At any meeting of the Securityholders, any
Securityholder entitled to vote thereat may vote by proxy, PROVIDED that no
proxy, shall be voted at any meeting unless it shall have been placed on file
with the Administrative Trustees, or with such other officer or agent of the
Trust as the Administrative Trustees may direct, for verification prior to the
time at which such vote shall be taken. Only Holders 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.

                                      -29-
<Page>

   SECTION 606.  SECURITYHOLDER ACTION BY WRITTEN CONSENT. Any action which may
be taken by the Securityholders at a meeting may be taken without a meeting if
the Securityholders holding more than a majority of all of the Outstanding Trust
Securities (based upon their aggregate Liquidation Amount) entitled to vote in
respect of such action (or such larger proportion thereof as shall be required
by any express provision of this Trust Agreement) shall consent to the action in
writing.

   SECTION 607.  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 or the Property Trustee may from time to time fix a
date, not more than 90 days prior to the date of any meeting of the
Securityholders or the payment of 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 608.  ACTS OF THE SECURITYHOLDERS. (a) 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 the
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 801) conclusive in favor of the Trustees, if made in the manner
provided in this Section 608.

     (b)  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 or her the execution thereof.
Where such execution is by a signer acting in a capacity other than his or her
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his or her 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.

     (c)  The ownership of the Preferred Securities shall be proved by the
Securities Register.

     (d)  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

                                      -30-
<Page>

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.

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

     (f)  A Securityholder may institute a legal proceeding directly against the
Depositor under the Guarantee to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee (as defined
in the Guarantee), the Trust or any Person.

   SECTION 609.  INSPECTION OF RECORDS. Upon reasonable notice to the
Administrative Trustees and the Property Trustee, the records of the Trust shall
be open to inspection at the principal executive office of the Trustee (as
indicated in Section 202) to Holders of the Trustee Securities during normal
business hours for any purpose reasonably related to such Securityholder's
interest as a Securityholder.

                                      -33-
<Page>

     Trust Agreement and the Securityholders shall be, as of such date, entitled

     by the Trust (or the Trustees on behalf of the Trust) under the laws of the
     State of Delaware or any political subdivision thereof in connection with
     the execution, delivery and performance by the Bank, the Property Trustee
     or the Delaware Trustee, as the case may be, of this Trust Agreement.

                                  ARTICLE VIII

                                    TRUSTEES

   SECTION 801.  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, by 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. No Administrative
Trustee nor the Delaware Trustee shall be liable for its act or omissions
hereunder except as a result of its own gross negligence or willful misconduct.
The Property Trustee's liability shall be determined under the Trust Indenture
Act. 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
801. To the extent that, at law or in equity, the Delaware Trustee or an
Administrative Trustee has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, the Delaware Trustee or
such Administrative 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 Delaware Trustee or the
Administrative Trustees otherwise existing at law or in equity, are agreed by
the Depositor and the Securityholders to replace such other duties and
liabilities of the Delaware Trustee and the Administrative Trustees, as the case
may be.

     (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 shall 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 801(b)
does not limit the liability of the Trustees expressly set forth elsewhere in
this Trust Agreement or, in the case of the Property Trustee, in the Trust
Indenture Act.

                                      -34-
<Page>

     (c)  No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, 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 Debentures 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
     Depositor 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 Property Trustee pursuant to Section 301 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 Depositor with their
     respective duties under this Trust Agreement, nor shall the Property
     Trustee be liable for the negligence, default or misconduct of the
     Administrative Trustees or the Depositor.

   SECTION 802.  CERTAIN NOTICES. (a) Within five (5) Business Days after the
occurrence of any Event of Default actually known to the Property Trustee, the
Property Trustee shall transmit, in the manner and to the extent provided in
Section 1008, notice of such Event of Default to the Securityholders, the
Administrative Trustees and the Depositor, unless such Event of Default shall
have been cured or waived. For purposes of this Section 802, the term "Event of
Default" means any event that is, or after notice or lapse of time or both would
become, an Event of Default.

     (b)  The Administrative Trustees shall transmit to the Securityholders in
the manner and to the extent provided in Section 1008 notice of the Depositor's
election to begin or further extend an Extended Interest Period on the
Debentures (unless such election shall have been revoked), and of any election
by the Depositor to accelerate the Maturity Date of the Debentures within the
time specified for transmitting such notice to the holders of the Debentures
pursuant to the Indenture as originally executed.

   SECTION 803.  CERTAIN RIGHTS OF THE PROPERTY TRUSTEE. Subject to the
provisions of Section 801:

          (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,
     debenture, 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;

          (b)     if (i) in performing its duties under this Trust Agreement the
     Property Trustee is required to decide between alternative courses of
     action to the extent not inconsistent with the treatment of the Trust as a
     grantor trust for federal income tax purposes; or (ii) in construing any of
     the provisions of this Trust Agreement, the Property Trustee finds the same
     ambiguous or inconsistent with other provisions contained herein; or (iii)
     the Property Trustee is unsure of the application of any provision of this
     Trust Agreement, then, except as to any matter as to which the Preferred
     Securityholders are entitled to vote under the terms of this Trust
     Agreement, the Property Trustee shall deliver a notice to the Depositor
     requesting written instructions of the Depositor as to the course of action
     to be taken 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 Depositor; PROVIDED,
     HOWEVER, that if the Property Trustee does not receive such instructions of
     the Depositor within ten (10) 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 (2) 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 Depositor 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 conclusively rely
     upon an Officers' Certificate which, upon receipt of such request, shall be
     promptly delivered by the Depositor 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, except as provided in Section 405,
     any filing under tax or securities laws) or any re-recording, refiling or
     reregistration thereof;

                                      -36-
<Page>

          (f)     the Property Trustee may consult with counsel of its choice
     (which counsel may be counsel to the Depositor or any of its Affiliates)
     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 Depositor 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, order 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 liabilities that might be incurred by it in compliance with
     such request, order or direction; nothing contained herein shall, however,
     relieve the Property Trustee of the obligation, upon the occurrence of an
     Event of Default (that has not been cured or waived) to exercise such of
     the rights and powers vested in it by this Trust Agreement, and to use the
     same degree of care and skill in their exercise as a prudent man would
     exercise or use under the circumstances in the conduct of his own affairs;

          (h)     the Property Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     consent, order, approval, bond, debenture, note or other evidence of
     indebtedness or other paper or document, unless requested in writing to do
     so by the Holders of not less than a majority in Liquidation Amount of the
     Securities, but the Property Trustee may make such further inquiry or
     investigation into such facts or matters as it may see fit;

          (i)     the Property Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     its agents or attorneys, PROVIDED that the Property Trustee shall be
     responsible for its own negligence or recklessness with respect to
     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

                                      -37-
<Page>

     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.

   SECTION 804.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES. The
Recitals contained herein and in the Trust Securities Certificates shall be
taken as the statements of the Trust, and the Trustees do not assume any
responsibility for their correctness. The Trustees shall not be accountable for
the use or application by the Depositor of the proceeds of the Debentures.

   SECTION 805.  MAY HOLD SECURITIES. Any Trustee or any other agent of any
Trustee or the Trust, in its individual or any other capacity, may become the
owner or pledgee of the Trust Securities and, subject to Sections 808 and 813
and except as provided in the definition of the term "Outstanding" in Article I,
may otherwise deal with the Trust with the same rights it would have if it were
not a Trustee or such other agent.

   SECTION 806.  COMPENSATION; INDEMNITY; FEES. The Depositor 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, in the case of the Property
     Trustee as set forth in a written agreement between the Depositor and the
     Property Trustee);

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

          (c)     to indemnify each of the Trustees or any predecessor Trustee
     for, and to hold the Trustees harmless against, any loss, damage, claims,
     liability, penalty or expense incurred without negligence or bad faith on
     its part, arising out of or in connection with the acceptance or
     administration of this Trust Agreement, including the costs and expenses of
     defending itself against any claim or liability in connection with the
     exercise or performance of any of its powers or duties hereunder, except
     any such expense, disbursement or advance as may be attributable to such
     Trustee's negligence, bad faith or willful misconduct (or, in the case of
     the Administrative Trustees or the Delaware Trustee, any such expense,
     disbursement or advance as may be attributable to its, his or her gross
     negligence, bad faith or willful misconduct).

                                      -38-

No Trustee may claim any Lien or charge on any Trust Property as a result of any
amount due pursuant to this Section 806.

   SECTION 807.  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 807,
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 807, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article VIII. The Property Trustee and the
Delaware Trustee may, but need not be, the same person.

     (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
through one or more persons authorized to bind such entity.

   SECTION 808.  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.

   SECTION 809.  CO-TRUSTEES AND SEPARATE TRUSTEE. (a) Unless a Debenture Event
of Default shall have occurred and be continuing, at any time or times, for the
purpose of meeting the legal requirements of the Trust Indenture Act or of any
jurisdiction in which any part of the Trust Property may at the time be located,
the Depositor shall have power to appoint, and upon the written request of the
Property Trustee, the Depositor shall for such purpose join with the Property
Trustee in the execution, delivery and performance of all instruments and
agreements necessary or proper to appoint, one or more Persons approved by the
Property Trustee either to act as co-trustee, jointly with the Property Trustee,
of all or any part of such Trust Property, or to 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 809. If
the Depositor does not join in such appointment within 15 days after the receipt
by it of a request so to do, or in case a Debenture Event of Default has
occurred and is continuing, the Property Trustee alone shall have

                                      -39-
<Page>

power to make such appointment. Any co-trustee or separate trustee appointed
pursuant to this Section 809 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.

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

     (c)  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:

            (i)   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.

           (ii)   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.

          (iii)   The Property Trustee at any time, by an instrument in writing
     executed by it, with the written concurrence of the Depositor, may accept
     the resignation of or remove any co-trustee or separate trustee appointed
     under this Section 809, and, in case a Debenture Event of Default has
     occurred and is continuing, the Property Trustee shall have the power to
     accept the resignation of, or remove, any such co-trustee or separate
     trustee without the concurrence of the Depositor. Upon the written request
     of the Property Trustee, the Depositor shall join with the Property Trustee
     in the execution, delivery and performance of all instruments and
     agreements necessary or proper to effectuate such resignation or removal. A
     successor to any co-trustee or separate trustee so resigned or removed may
     be appointed in the manner provided in this Section 809.

           (iv)   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.

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

                                      -40-
<Page>

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

   SECTION 810.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR. (a) No
resignation or removal of any Trustee (the "RELEVANT TRUSTEE") and no
appointment of a successor Trustee pursuant to this Article VIII shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 811.

     (b)  Subject to the immediately preceding paragraph, the Relevant Trustee
may resign at any time with respect to the Trust Securities by giving written
notice thereof to the Securityholders. If the instrument of acceptance by the
successor Trustee required by Section 811 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, at the expense of the Depositor, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee with
respect to the Trust Securities.

     (c)  Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by an Act of the Common
Securityholder. If a Debenture 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 an 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.

     (d)  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 Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by an Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees with respect to the Trust Securities and the Trust, and the successor
Trustee shall comply with the applicable requirements of Section 811. 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 a Debenture Event of Default shall have
occurred and is continuing, the Preferred Securityholders, by an 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 with respect to the Trust
Securities and the Trust, and such successor Trustee shall comply with the
applicable requirements of Section 811. If an Administrative Trustee shall
resign, be removed or become incapable of acting as an Administrative Trustee,
at a time when a Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by an Act of the Common Securityholder
delivered to an Administrative Trustee, shall promptly appoint a successor
Administrative Trustee or Administrative Trustees with respect to the Trust
Securities and the Trust, and such successor Administrative Trustee or
Administrative Trustees shall comply with the applicable requirements of Section
811. If no successor Relevant Trustee with respect to the Trust Securities shall
have been so appointed by the Common Securityholder or the Preferred
Securityholders and accepted appointment in the manner required by Section 811,
any Securityholder who has been a Securityholder of Trust Securities for six

                                      -41-
<Page>

consecutive months on behalf of himself or herself and all others similarly
situated may petition a court of competent jurisdiction for the appointment of a
successor Relevant Trustee with respect to the Trust Securities.

     (e)  The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all the
Securityholders in the manner provided in Section 1008 and shall give notice to
the Depositor. 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.

     (f)  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 Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of the remaining Administrative Trustees
if there are at least two of them; or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees set forth in Section 807).

   SECTION 811.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) In case of the
appointment hereunder of a successor Relevant Trustee with respect to the Trust
Securities and the Trust, the retiring Relevant Trustee and each successor
Relevant Trustee with respect to the Trust Securities shall execute and deliver
an instrument hereto wherein each successor Relevant Trustee shall accept such
appointment and which 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 upon the
execution and delivery of such instrument 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 with respect to the Trust Securities and the
Trust; but, 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 the Trust Property, all proceeds thereof and
money held by such retiring Relevant Trustee hereunder with respect to the Trust
Securities and the Trust.

     (b)  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 immediately preceding paragraph, as the case may be.

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

   SECTION 812.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.
Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee may be merged or converted or with which it may be
consolidated, or any Person resulting from any

                                      -42-
<Page>

merger, conversion or consolidation to which such Relevant Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of such Relevant Trustee, shall be the successor of such Relevant
Trustee hereunder, PROVIDED such Person shall be otherwise qualified and
eligible under this Article VIII, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.

   SECTION 813.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE DEPOSITOR OR THE
TRUST. If and when the Property Trustee or the Delaware Trustee shall be or
become a creditor of the Depositor or the Trust (or any other obligor upon the
Debentures or the Trust Securities), the Property Trustee 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 Depositor or the Trust (or any
such other obligor).

   SECTION 814.  REPORTS BY THE PROPERTY TRUSTEE. (a) The Property Trustee shall
transmit to the Securityholders such reports concerning the Property Trustee,
its actions under this Trust Agreement and the property and funds in its
possession in its capacity as the Property Trustee as may be required pursuant
to the Trust Indenture Act at the times and in the manner provided pursuant
thereto.

     (b)  A copy of each such report shall, at the time of such transmission to
the Holders, be filed by the Property Trustee with the American Stock Exchange,
Inc., and each national securities exchange or other organization upon which the
Trust Securities are listed, and also with the Commission and the Depositor.

   SECTION 815.  REPORTS TO THE PROPERTY TRUSTEE. The Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information 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 816.  EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT. Each of the
Depositor and the Administrative Trustees on behalf of the Trust shall provide
to the Property Trustee such evidence of compliance with any conditions
precedent, if any, provided for in this Trust Agreement 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.

   SECTION 817.  NUMBER OF TRUSTEES. (a) The number of Trustees shall be five,
PROVIDED that the Holder of all of the Common Securities by written instrument
may increase or decrease the number of the Administrative Trustees. The Property
Trustee and the Delaware Trustee may be the same Person.

     (b)  If a Trustee ceases to hold office for any reason and the number of
the Administrative Trustees is not reduced pursuant to Section 817(a), or if the
number of the Trustees is increased pursuant to Section 817(a), a vacancy shall
occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 810.

                                      -43-
<Page>

     (c)  The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of a Trustee shall not operate to annul the
Trust. Whenever a vacancy in the number of the Administrative Trustees shall
occur, until such vacancy is filled by the appointment of an Administrative
Trustee in accordance with Section 810, 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 818.  DELEGATION OF POWER. (a) Any Administrative Trustee may, by
power of attorney consistent with applicable law, delegate to any other natural
person over the age of 21 his or her power for the purpose of executing any
documents contemplated in Section 207(a); and

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

   SECTION 819.  VOTING. Except as otherwise provided in this Trust Agreement,
the consent or approval of the Administrative Trustees shall require consent or
approval by not less than a majority of the Administrative Trustees, unless
there are only two, in which case both must consent.

                                   ARTICLE IX

                       TERMINATION, LIQUIDATION AND MERGER

   SECTION 901.  TERMINATION UPON EXPIRATION DATE. Unless earlier dissolved,
the Trust shall automatically dissolve on June 30, 2034 (the "EXPIRATION DATE")
subject to distribution of the Trust Property in accordance with Section 904.

   SECTION 902.  EARLY TERMINATION. The first to occur of any of the following
events is an "Early Termination Event":

          (a)     the occurrence of a Bankruptcy Event in respect of, or the
     dissolution or liquidation of, the Depositor;

          (b)     delivery of written direction to the Property Trustee by the
     Depositor at any time (which direction is wholly optional and within the
     discretion of the Depositor, subject to Depositor having received prior
     approval of the Board of Governors of the Federal Reserve System if so
     required under applicable guidelines, policies or regulations thereof) to
     dissolve the Trust and distribute the Debentures to the Securityholders in
     exchange for the Preferred Securities in accordance with Section 904;

                                      -44-
<Page>

          (c)     the redemption of all of the Preferred Securities in
     connection with the redemption of all of the Debentures (whether upon a
     Debenture Redemption Date or the maturity of the Debenture); and

          (d)     the entrance of an order for dissolution of the Trust by a
     court of competent jurisdiction.

   SECTION 903.  TERMINATION. The respective obligations and responsibilities of
the Trustees and the Trust created and continued hereby shall terminate upon the
latest to occur of the following: (a) the distribution by the Property Trustee
to the Securityholders upon the liquidation of the Trust pursuant to Section
904, or upon the redemption of all of the Trust Securities pursuant to Section
402, of all amounts required to be distributed hereunder upon the final payment
of the Trust Securities; (b) the payment of any expenses owed by the Trust; (c)
the discharge of all administrative duties of the Administrative Trustees,
including the performance of any tax reporting obligations with respect to the
Trust or the Securityholders; and (d) the filing of a Certificate of
Cancellation by the Administrative Trustee under the Delaware Statutory Trust
Act.

   SECTION 904.  LIQUIDATION. (a) If an Early Termination Event specified in
clause (a), (b), or (d) of Section 902 occurs or upon the Expiration Date, the
Trust shall be liquidated by the Trustees as expeditiously as the Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to each Securityholder a
Like Amount of Debentures, subject to Section 904(d). Notice of liquidation
shall be given by the Property Trustee by first-class mail, postage prepaid,
mailed not later than 30 nor more than 60 days prior to the Liquidation Date to
each Holder of Trust Securities at such Holder's address appearing in the
Securities Register. All notices of liquidation shall:

            (i)   state the Liquidation Date;

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

          (iii)   provide such information with respect to the mechanics by
     which the Holders may exchange the Trust Securities Certificates for the
     Debentures, or, if Section 904(d) applies, receive a Liquidation
     Distribution, as the Administrative Trustees or the Property Trustee shall
     deem appropriate.

     (b)  Except where Section 902(c) or 904(d) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to the
Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

                                      -45-
<Page>

     (c)  Except where Section 902(c) or 904(d) applies, after the Liquidation
Date, (i) the Trust Securities shall no longer be deemed to be Outstanding; (ii)
certificates representing a Like Amount of the Debentures shall be issued to the
Holders of Trust Securities Certificates upon surrender of such certificates to
the Administrative Trustees or their agent for exchange; (iii) the Depositor
shall use its best efforts to have the Debentures listed on the Nasdaq National
Market or on such other securities exchange or other organization as the
Preferred Securities are then listed or traded; (iv) any Trust Securities
Certificates not so surrendered for exchange shall be deemed to represent a Like
Amount of Debentures, accruing interest at the rate provided for in the
Debentures from the last Distribution Date on which a Distribution was made on
such Trust Securities Certificates until such certificates are so surrendered
(and until such certificates are so surrendered, no payments of interest or
principal shall be made to Holders of the Trust Securities Certificates with
respect to such Debentures); and (v) all rights of the Securityholders holding
the Trust Securities shall cease, except the right of such Securityholders to
receive the Debentures upon surrender of the Trust Securities Certificates.

     (d)  In the event that, notwithstanding the other provisions of this
Section 904, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Property Trustee in such manner as the
Property Trustee determines. In such event, on the date of the dissolution,
winding-up or other termination of the Trust, the Securityholders shall be
entitled to receive out of the assets of the Trust available for distribution to
the 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
dissolution, winding-up or termination, 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, subject to Section 407).
The Holder of the Common Securities shall be entitled to receive the Liquidation
Distributions upon any such dissolution, winding-up or termination pro rata
(determined as aforesaid) with the Holders of the Preferred Securities, except
that, if a Debenture Event of Default has occurred and is continuing, the
Preferred Securities shall have a priority over the Common Securities.

   SECTION 905.  MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE
TRUST. The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except pursuant
to this Section 905. At the request of the Depositor, 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, amalgamate, 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 (a) such successor
entity either (i) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities; or (ii) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "SUCCESSOR SECURITIES") so long as

                                      -46-
<Page>

the Successor Securities rank the same as the Preferred Securities rank in
priority with respect to distributions and payments upon liquidation, redemption
and otherwise; (b) the Depositor expressly appoints a trustee of such successor
entity possessing substantially the same powers and duties as the Property
Trustee as the holder of the Debentures; (c) the Successor Securities are listed
or traded, or any Successor Securities shall be listed or traded upon
notification of issuance, on any national securities exchange or other
organization on which the Preferred Securities are then listed, if any; (d) such
merger, consolidation, 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; (e) such successor entity has a purpose substantially identical to that
of the Trust; (f) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Depositor has received an
Opinion of Counsel to the effect that (i) such merger, consolidation,
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; and
(ii) following such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, neither the Trust nor such successor entity shall
be required to register as an "investment company" under the Investment Company
Act; and (g) the Depositor 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, the
Debentures, this Trust Agreement and the Expense Agreement. For purposes of this
Section 905, any such consolidation, merger, sale, conveyance, transfer or other
disposition as a result of which (a) the Company is not the surviving Person,
and (b) the same Person is not both (i) the primary obligor in respect of the
Debentures and (ii) the Guarantor under that certain Preferred Securities
Guarantee Agreement of even date herewith (the "GUARANTEE") between the Company
and Wilmington Trust Company, shall be deemed to constitute a replacement of the
Trust by a successor entity; PROVIDED FURTHER that, notwithstanding the
foregoing, in the event that upon the consummation of such a consolidation,
merger, sale, conveyance, transfer or other disposition, the parent company (if
any) of the Company, or its successor, is a bank holding company or financial
holding company or comparably regulated financial institution, such parent
company shall guarantee the obligations of the Trust (and any successor thereto)
under the Preferred Securities (including any Successor Securities) at least to
the extent provided by the Guarantee, the Debentures, the Trust Agreement and
the Expense Agreement. Notwithstanding the foregoing, the Trust shall not,
except with the consent of the Holders of 100% in Liquidation Amount of the
Preferred Securities, consolidate, amalgamate, merge with or 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 Person to consolidate,
amalgamate, merge with or into, or replace it if such consolidation,
amalgamation, merger or replacement 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 1001. LIMITATION OF RIGHTS OF THE SECURITYHOLDERS. The death or
incapacity of any Person having an interest, beneficial or otherwise, in the
Trust Securities shall not operate to terminate this Trust Agreement, nor
entitle the legal representatives or heirs of such Person or any Securityholder
for such Person to claim an accounting, take any action or bring any proceeding
in any court for a partition or winding-up of the arrangements contemplated
hereby, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

   SECTION 1002. AMENDMENT. (a) This Trust Agreement may be amended from time to
time by the Trustees and the Depositor, without the consent of any
Securityholders, (i) as provided in Section 811 with respect to acceptance of
appointment by a successor Trustee; (ii) to cure any ambiguity, correct or
supplement any provision herein or therein which may be inconsistent with any
other provision herein or therein, or to make any other provisions with respect
to matters or questions arising under this Trust Agreement, that shall not be
inconsistent with the other provisions of this Trust Agreement; (iii) to modify,
eliminate or add to any provisions of this Trust Agreement to such extent as
shall be necessary to ensure that the Trust shall be classified for United
States federal income tax purposes as a grantor trust at all times that any of
the Trust Securities are Outstanding or to ensure that the Trust shall not be
required to register as an "investment company" under the Investment Company
Act; or (iv) to reduce or increase the Liquidation Amount per Trust Security and
simultaneously to correspondingly increase or decrease the number of Trust
Securities issued and Outstanding solely for the purpose of maintaining the
eligibility of the Preferred Securities for quotation or listing on any national
securities exchange or other organization on which the Preferred Securities are
then quoted or listed (including, if applicable, the Nasdaq National Market);
PROVIDED, HOWEVER, that in the case of clause (ii), such action shall not
adversely affect in any material respect the interests of any Securityholder,
and PROVIDED FURTHER, that in the case of clause (iv) the aggregate Liquidation
Amount of the Trust Securities Outstanding upon completion of any such reduction
must be the same as the aggregate Liquidation Amount of the Trust Securities
Outstanding immediately prior to such reduction or increase, and any amendments
of this Trust Agreement shall become effective when notice thereof is given to
the Securityholders (or, in the case of an amendment pursuant to clause (iv), as
of the date specified in the notice).

     (b)  Except as provided in Section 601(c) or Section 1002(c) hereof, any
provision of this Trust Agreement may be amended by the Trustees and the
Depositor (i) with the consent of the Trust Securityholders representing not
less than a majority (based upon Liquidation Amounts) of the Trust Securities
then Outstanding; and (ii) upon receipt by the Trustees of an Opinion of Counsel
to the effect that such amendment or the exercise of any power granted to the
Trustees in accordance with such amendment shall not affect the Trust's status
as a grantor trust for United States federal income tax purposes or the Trust's
exemption from status of an "investment company" under the Investment Company
Act.

                                      -48-
<Page>

     (c)  In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder (such consent
being obtained in accordance with Section 603 or 606 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date; or (ii) restrict the right of a Securityholder to institute suit

(such consent being obtained in accordance with Section 603 or 606 hereof), this
paragraph (c) of this Section 1002 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 Investment Company Act or to 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 Depositor, this Trust Agreement may not be amended in
a manner which imposes any additional obligation on the Depositor.

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

     (g)  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 shall be entitled to receive an Opinion of Counsel and an Officers'
Certificate stating that any amendment to this Trust Agreement has been effected
in compliance with this Trust Agreement.

obligations of each of the Securityholders, the Trust and the Trustees with

accordance with and governed by the laws of the State of Delaware (without
regard to its conflict of laws principles).

   SECTION 1005. PAYMENTS DUE ON NON-BUSINESS DAY. If the date fixed for any

the next succeeding calendar year, such payment shall be made on the

                                      -49-

immediately preceding Business Day (and without any reduction of interest or any
other payment in respect of any such acceleration), in each case with the same
force and effect as though made on the date fixed for such payment, and no
distribution shall accumulate thereon for the period after such date.

   SECTION 1006. SUCCESSORS. This Trust Agreement shall be binding upon and
shall inure to the benefit of any successor to the Depositor, the Trust or the
Relevant Trustee(s), including any successor by operation of law. Except in
connection with a consolidation, merger or sale involving the Depositor that is
permitted under Article XII of the Indenture and pursuant to which the assignee
agrees in writing to perform the Depositor's obligations hereunder, the
Depositor shall not assign its obligations hereunder.

   SECTION 1007. HEADINGS. The Article and Section headings are for convenience
only and shall not affect the construction of this Trust Agreement.

   SECTION 1008. REPORTS, NOTICES AND DEMANDS. Any report, notice, demand or
other communication which by any provision of this Trust Agreement is required
or permitted to be given or served to or upon any Securityholder or the
Depositor may be given or served in writing by deposit thereof, first-class

transmission, in each case, addressed, (a) in the case of a Preferred
Securityholder, to such Preferred Securityholder as such Securityholder's name
and address may appear on the Securities Register; and (b) in the case of the
Common Securityholder or the Depositor, to Old Second Bancorp, Inc., 37 River
Street, Aurora, Illinois 60506-4172, Attention: Chief Executive Officer,
facsimile no.: (630) 906-3208. Any notice to the Preferred Securityholders shall
also be given to such owners as have, within two years preceding the giving of
such notice, filed their names and addresses with the Property Trustee for that
purpose. Such notice, demand or other communication to or upon a Securityholder
shall be deemed to have been sufficiently given or made, for all purposes, upon
hand delivery, mailing or transmission.

     Any notice, demand or other communication which by any provision of this
Trust Agreement is required or permitted to be given or served to or upon the
Trust, the Property Trustee or the Administrative Trustees shall be given in
writing addressed (until another address is published by the Trust) as follows:
(a) with respect to the Property Trustee to Wilmington Trust Company, Rodney
Square North, 1100 North Market Street, Wilmington, Delaware 19890-0001,
Attention: Corporate Trust Administration; (b) with respect to the Delaware
Trustee, to Wilmington Trust Company, at the address above; and (c) with respect
to the Administrative Trustees, to them at the address above for notices to the

Trust I, c/o Chief Executive Officer, Old Second Bancorp, Inc." Such notice,
demand or other communication to or upon the Trust or the Property Trustee shall
be deemed to have been sufficiently given or made only upon actual receipt of
the writing by the Trust or the Property Trustee.

   SECTION 1009. AGREEMENT NOT TO PETITION. Each of the Trustees and the
Depositor agrees 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

                                      -50-
<Page>

(including, without limitation, the United States Bankruptcy Code of 1978, as
amended) (collectively, "BANKRUPTCY LAWS") or otherwise join in the commencement
of any proceeding against the Trust under any Bankruptcy Law. In the event the
Depositor or any of the Trustees takes action in violation of this Section 1009,
the Property Trustee agrees, for the benefit of the Securityholders, that at the
expense of the Depositor (which expense shall be paid prior to the filing), it
shall file an answer with the bankruptcy court or otherwise properly contest the
filing of such petition by the Depositor or such Trustee against the Trust or
the commencement of such action and raise the defense that the Depositor or such
Trustee has agreed in writing not to take such action and should be stopped and
precluded therefrom. The provisions of this Section 1009 shall survive the
termination of this Trust Agreement.

   SECTION 1010. TRUST INDENTURE ACT; CONFLICT WITH TRUST INDENTURE ACT. (a)
This Trust Agreement is subject to the provisions of the Trust Indenture Act
that are required to be part of this Trust Agreement and shall, to the extent
applicable, be governed by such provisions.

     (b)  The Property Trustee shall be the only Trustee which is a trustee for
the purposes of the Trust Indenture Act.

     (c)  If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Trust Agreement by any
of the provisions of the Trust Indenture Act, such required provision shall
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 to be excluded, as the case may be.

     (d)  The application of the Trust Indenture Act to this Trust Agreement
shall not affect the nature of the Trust Securities as equity securities
representing undivided beneficial interests in the assets of the Trust.

   SECTION 1011. ACCEPTANCE OF TERMS OF THE TRUST AGREEMENT, THE GUARANTEE AND
THE INDENTURE. The receipt and acceptance of a trust security or any interest
therein by or on behalf of a Securityholder or any Beneficial Owner, without any
signature or further manifestation of assent, shall constitute the unconditional
acceptance by the Securityholder and all others having a beneficial interest in
such trust security of all the terms and provisions of this Trust Agreement and
agreement to the subordination provisions and other terms of the guarantee and
the Indenture, and shall constitute the agreement of the trust, such
Securityholder and such others that the terms and provisions of this Trust
Agreement shall be binding, operative and effective as between the trust and
such Securityholder and such others. Without limiting the foregoing, by
acceptance of a preferred security, each holder thereof shall be deemed to have
agreed to treat, for all United States federal income tax and financial
accounting purposes, the debentures as indebtedness of the Company and the
preferred securities as evidencing an undivided beneficial ownership interest in
the Debentures.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed all as of the day and year first written above.
