                                 TRUST AGREEMENT

TRUST AGREEMENT, dated as of January 3, 2001 by and between Spectrum
Bancorporation, Inc., an Iowa corporation, as "Depositor," and Wilmington
Trust Company, a Delaware banking corporation, as "Trustee."

Section 1. The Trust. The trust created hereby shall be known as Spectrum
Capital Trust II (the "Trust"), in which name the Trustee, or the Depositor to
the extent provided herein, may conduct the business of the Trust, make and
execute contracts, and sue and be sued.

Section 2. The Trust Estate. The Depositor hereby assigns, transfers, conveys
and sets over to the Trustee the sum of $10.00. The Trustee hereby acknowledges
receipt of such amount in trust from the Depositor, which amount shall
constitute the initial trust estate. The Trustee hereby declares that it will
hold the trust estate in trust for the Depositor. It is the intention of the
parties hereto that the Trust created hereby constitute a business trust under
Chapter 38 of Title 12 of the Delaware Code, 12 Del. C. Section 3801, et seq.
(the "Business Trust Act"), and that this document constitute the governing
instrument of the Trust. The Trustee is hereby authorized and directed to
execute and file a certificate of trust with the Delaware Secretary of State in
accordance with the provisions of the Business Trust Act.

Section 3. Amended and Restated Trust Agreement. The Depositor, the Trustee and
certain other parties will enter into an amended and restated Trust Agreement,
satisfactory to each such party and substantially in the form to be included as
an exhibit to the 1933 Act Registration Statement (as defined below), to provide
for the contemplated operation of the Trust created hereby and the issuance of
the Preferred Securities (as defined below) and common securities of the Trust
to be referred to therein. Prior to the execution and delivery of such amended
and restated Trust Agreement, the Trustee shall not 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-1
(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
(b) a Registration Statement on Form 8-A (including all pre-

effective and post-effective amendments thereto) relating to the registration of
the Preferred Securities of the Trust under the Securities Exchange Act of 1934,
as amended; (ii) to file with the American Stock Exchange, Inc. and execute on
behalf of the Trust a listing application or applications and all other
applications, statements, certificates, agreements and other instruments as
shall be necessary or desirable to cause the Preferred Securities to be listed
on the American Stock Exchange; (iii) to file and execute on behalf of the Trust
such applications, reports, surety bonds, irrevocable consents, appointments of
attorney for service of process and other papers and documents as the Depositor,
on behalf of the Trust, may deem necessary or desirable to register the
Preferred Securities under the securities or "Blue Sky" laws; and (iv) to
execute on behalf of the Trust such Underwriting Agreements with one or more
underwriters relating to the offering of the Preferred Securities as the
Depositor, on behalf of the Trust, may deem necessary or desirable. In the event
that any filing referred to in clauses (i), (ii) and (iii) above is required by
the rules and regulations of the Commission, the American Stock Exchange or
state securities or "Blue Sky" laws to be executed on behalf of the Trust by a
Trustee, the Depositor and any Trustee appointed pursuant to Section 6 hereof
are hereby authorized to join in any such filing 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 the Depositor.

Section 7. Governing Law. This Trust Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware (without regard
to conflicts of law of principles).

Section 8.

     (a)  The Trustee and its officers, directors, agents and servants
(collectively, the "Fiduciary Indemnified Persons") shall not be liable,
responsible or accountable in damages or otherwise to the Trust, the Depositor,
the Trustees or any holder of the Preferred Securities (the Trust, the Depositor
and any holder of the Trust Securities being a "Covered Person") for any loss,
damage or claim incurred by reason of any act

<PAGE>

or omission performed or omitted by the Fiduciary Indemnified Persons in good
faith on behalf of the Trust and in a manner the Fiduciary Indemnified Persons
reasonably believed to be within the scope of authority conferred on the
Fiduciary Indemnified Persons by this Trust Agreement or by law, except that the
Fiduciary Indemnified Persons shall be liable for any such loss, damage or claim
incurred by reason of the Fiduciary Indemnified Person's negligence or willful
misconduct with respect to such acts or omissions.

     (b)  The Fiduciary Indemnified Persons shall be fully protected in relying
in good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any person as to matters the
Fiduciary Indemnified Persons reasonably believes are within such other person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which distributions to holders of Preferred Securities might properly be paid.

     (c)  The Depositor agrees, to the fullest extent permitted by applicable
law, (i) to indemnify and hold harmless each Fiduciary Indemnified Person, or
any of its officers, directors, shareholders, employees, representatives or
agents, from and against any loss, damage, liability, tax, penalty, expense or
claim of any kind or nature whatsoever incurred by the Fiduciary Indemnified
Persons by reason of the creation, operation or termination of the Trust in a
manner the Fiduciary Indemnified Persons reasonably believed to be within the
scope of authority conferred on the Fiduciary Indemnified Persons by this Trust
Agreement of Trust, except that no Fiduciary Indemnified Persons shall be
entitled to be indemnified in respect of any loss, damage or claim incurred by
the Fiduciary Indemnified Persons by reason of negligence or willful misconduct
with respect to such acts or omissions, and (ii) to advance expenses (including
legal fees) incurred by a Fiduciary Indemnified Person in defending any claim,
demand, action, suit or proceeding shall, from time to time, prior to the final
disposition of such claim, demand, action, suit or proceeding, upon receipt by
the Trust of an undertaking by or on behalf of such Fiduciary Indemnified
Persons to repay such amount if it shall be determined that such Fiduciary
Indemnified Person is not entitled to be indemnified as authorized in the
preceding subsection.

     (d)  The provisions of Section 8 shall survive the termination of this
Trust Agreement or the earlier resignation or removal of the Fiduciary
Indemnified Persons.

company" required to be registered under the Investment Company Act, will 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 Junior
Subordinated Debentures will 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, not inconsistent with applicable law or this Trust Agreement,
that each of the Depositor and the Administrative Trustees determines in their

                            DISTRIBUTIONS; REDEMPTION

     SECTION 401. DISTRIBUTIONS.

     (a)  Distributions on the Trust Securities shall be cumulative, and will
accumulate whether or not there are funds of the Trust available for the payment
of Distributions. Distributions shall accumulate from _______________, 2001,
and, except during any Extension Period with respect to the Junior Subordinated
Debentures, shall be payable quarterly in arrears on the last day of January,
April, July, and October in each year, commencing April 30, 2001. The amount of
each Distribution due with respect to the Trust Securities will include amounts
accrued through the date the Distribution payment is due. 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, payment of such Distribution shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date (each date on which Distributions are payable in accordance with
this Section 401(a) is a "Distribution Date").

     (b)  The Trust Securities represent undivided beneficial interests in the
Trust Property, and, as a practical matter, the Distributions on the Trust
Securities shall be payable at a rate of _____% per annum 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 Extension Period with respect to the Junior Subordinated Debentures,
Distributions on the Preferred Securities will be deferred for a period equal to
the Extension 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 in the Payment Account for the payment of such
Distributions.

                                       17
<PAGE>

     (d)  Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which shall be
one Business Day prior to such Distribution Date; provided, however, that in the
event that the Preferred Securities do not remain in book-entry-only form, the
relevant record date shall be the 1st day of the month in which the relevant
Distribution Date occurs.

     SECTION 402. REDEMPTION.

     (a)  On each Debenture Redemption Date and on the Maturity Date of the
Junior Subordinated Debentures, the Trust will be required to redeem a Like
Amount of Trust Securities at the Redemption Price.

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

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

     (c)  The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Junior Subordinated 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, Wilmington, Delaware time, on the
Redemption Date, subject to Section 402(c), the Property Trustee will, so long
as the Preferred Securities are in book-entry-only form, deposit with the
Clearing Agency for the Preferred

                                       18
<PAGE>

Securities funds sufficient to pay the applicable Redemption Price and will give
such Clearing Agency irrevocable instructions and authority to pay the
Redemption Price to the Holders thereof. If the Preferred Securities are no
longer in book-entry-only form, the Property Trustee, subject to Section 402(c),
will deposit with the Paying Agent funds sufficient to pay the applicable
Redemption Price and will give the Paying Agent irrevocable instructions and
authority to pay the Redemption Price to the Holders thereof upon surrender of
their 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, all rights of Security holders holding Trust Securities so
called for redemption will cease, except the right of such Security holders to
receive the Redemption Price, but without interest on such Redemption Price, and
such Securities will cease to be Outstanding. In the event that any date on
which any Redemption Price is payable is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), except that, if such Business Day falls in the next calendar
year, such payment will be made on the immediately preceding Business Day, in
each case, with the same force and effect as if made on such date. In the event
that payment of the Redemption Price in respect of any Trust Securities called
for redemption is improperly withheld or refused and not paid either by the
Trust or by the Depositor pursuant to the Guarantee, Distributions on such Trust
Securities will 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 will 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 one Business Day
prior to the relevant Redemption Date; provided, however, that in the event that
the Preferred Securities do not remain in book-entry-only form, the relevant
record date shall be the date fifteen days prior to the relevant Redemption
Date. In the case of a liquidation, the record date will be established by the
Property Trustee and be no more than forty-five days prior to the liquidation
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 $10 or an integral multiple of

                                       19
<PAGE>

$10 in excess thereof) of the Liquidation Amount of Preferred Securities of a
denomination larger than $10. 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 Preferred Securities shall relate, in the case of
any Preferred Securities redeemed or to be redeemed only in part, to the portion
of the Liquidation Amount of Preferred Securities which has been or is to be
redeemed.

     SECTION 403. SUBORDINATION OF 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 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, 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 Common Securities will be deemed to
have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities 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 will 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 shall credit the relevant Persons'
accounts at such Clearing Agency on the applicable Distribution Dates. Payments
in respect of the Common Securities shall be

                                       20
<PAGE>

made in such manner as shall be mutually agreed between the Property Trustee and
the Holder of the Common Securities.

     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 Form required to be filed in
respect of the Trust in each taxable year of the Trust and (b) prepare and
furnish (or cause to be prepared and furnished) to each Securityholder the
appropriate Internal Revenue Service form required to be furnished to such
Securityholder or the information required to be provided on such form. 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 Security holders under the Trust Securities.

     SECTION 406. PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST. Upon receipt
under the Junior Subordinated Debentures of Additional Sums, 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 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.

                                   ARTICLE V.

                          TRUST SECURITIES CERTIFICATES

     SECTION 501. INITIAL OWNERSHIP. Upon the creation of the Trust and the
contribution by the Depositor pursuant to Section 203 and until the issuance of
the Trust Securities, and at any time during which no Trust Securities are
outstanding, the Depositor shall be the sole beneficial owner of the Trust.

     SECTION 502. THE TRUST SECURITIES CERTIFICATES. The Preferred Securities
Certificates shall be issued in minimum denominations of $10 Liquidation Amount
and integral multiples of $10 in excess thereof, and the Common Securities
Certificates shall be issued in denominations of $10 Liquidation Amount and
integral multiples of $10 in excess thereof. The Trust Securities Certificates
shall be executed on behalf of the Trust by manual signature of at least one
Administrative Trustee. Trust Securities Certificates bearing the manual
signatures of individuals who were, at the time when such signatures shall have
been affixed, authorized to sign on behalf of the Trust,

                                       21
<PAGE>

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 513.

     SECTION 503. EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES. On
the Closing Date, 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 at least one of the Administrative
Trustees and delivered to or upon the written order of the Depositor, signed by
its Vice Chairman, its President, or any Vice President without further
corporate action by the Depositor, in authorized denominations.

     SECTION 504. REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED SECURITIES
CERTIFICATES. 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 Trust Securities Certificates and transfers and exchanges
of 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 Preferred Securities Certificates and Common
Securities Certificates (subject to Section 510 in the case of the Common
Securities Certificates) and registration of transfers and exchanges of
Preferred Securities Certificates as herein provided. The Property Trustee shall
be the initial Securities Registrar.

     Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or agency maintained pursuant to Section 508, the
Administrative Trustees or any one of them shall execute and deliver, in the
name of the designated transferee or transferees, one or more new Preferred
Securities Certificates in authorized denominations of a like aggregate
Liquidation Amount dated the date of execution by such Administrative Trustee or
Trustees. The Securities Registrar shall not be required to register the
transfer of any Preferred Securities that have been called for redemption. At
the option of a Holder, Preferred Securities Certificates may be exchanged for
other Preferred Securities Certificates in authorized denominations of the same
class and of a like aggregate Liquidation Amount upon surrender of the Preferred
Securities Certificates to be exchanged at the office or agency maintained
pursuant to Section 508.

     Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Property Trustee and the
Securities Registrar duly executed by the Holder or such Holder's 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

                                       22
<PAGE>

practice. The Trust shall not be required to (i) issue, register the transfer
of, or exchange any 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 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 Preferred Securities so selected for redemption, in whole or in
part, except the unredeemed portion of any such Preferred Securities being
redeemed in part.

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

     SECTION 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 and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees, or any one of them, on behalf of the
Trust shall execute and make available for delivery, in exchange for or in lieu
of any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a
new Trust Securities Certificate of like class, tenor and denomination. In
connection with the issuance of any new Trust Securities Certificate under this
Section, the Administrative Trustees or the Securities Registrar may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection therewith. Any duplicate Trust Securities
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an undivided beneficial 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 SECURITY HOLDERS. 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 SECURITY HOLDERS' 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) semi-annually on or before January
15 and July 15 in each year, a list, in such form as the Property Trustee may
reasonably require, of the names and addresses of the Security holders as of the
most recent regular record date (as provided in Section 401(d)) and (b) promptly
after receipt by any Administrative Trustee or

                                       23
<PAGE>

the Depositor of a request therefor from the Property Trustee, such other
information as the Property Trustee may reasonably require 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 Security holders to communicate
with other Security holders 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 an office or offices or agency or agencies where Preferred
Securities Certificates may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Trustees in respect of the
Trust Securities Certificates may be served. The Administrative Trustees
initially designate the principal corporate trust office of the Property
Trustee, Rodney Square North, 1100 North Market Street, Wilmington, Delaware
19890-0001, Attn: Corporate Trust Administration, as the principal corporate
trust office for such purposes. The Administrative Trustees shall give prompt
written notice to the Depositor and to the Security holders of any change in the
location of the Securities Register or any such office or agency.

     SECTION 509. APPOINTMENT OF PAYING AGENT. The Paying Agent shall make
Distributions to Security holders 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. The Paying Agent shall initially be the Property Trustee, and
any co-paying agent chosen by the Property Trustee, and acceptable to the
Administrative Trustees and the Depositor. 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 that is acceptable to the Property Trustee
and the Depositor to act as Paying Agent (which shall be a bank or trust
company). The Administrative Trustees shall cause such successor Paying Agent or
any additional Paying Agent appointed by the Administrative Trustees to execute
and deliver to the Trustees an instrument in which such successor Paying Agent
or additional Paying Agent shall agree with the Trustees that as Paying Agent,
such successor Paying Agent or additional Paying Agent will hold all sums, if
any, held by it for payment to the Security holders in trust for the benefit of
the Security

                                       24
<PAGE>

holders entitled thereto until such sums shall be paid to such Security holders.
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 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
Agreement to the Paying Agent shall include any co-paying agent unless the
context requires otherwise.

     SECTION 510. OWNERSHIP OF COMMON SECURITIES BY 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. BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES CERTIFICATE.

          (a)  The Preferred Securities Certificates, upon original issuance,
     will be issued in the form of a typewritten Preferred Securities
     Certificate or Certificates representing Book-Entry Preferred Securities
     Certificates, to be delivered to or held on behalf of The Depository Trust
     Company, the initial Clearing Agency, by, or on behalf of, the Trust. Such
     Book-Entry Preferred Securities Certificate or Certificates shall initially
     be registered on the Securities Register in the name of Cede & Co., the
     nominee of the initial Clearing Agency, and no beneficial owner will
     receive a Definitive Preferred Securities Certificate representing such
     beneficial owner's interest in such Preferred Securities, except as
     provided in Section 513. Unless and until Definitive Preferred Securities
     Certificates have been issued to beneficial owners pursuant to Section 513:

               (i)  the provisions of this Section 511(a) shall be in full force
          and effect;

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

               (iii) to the extent that the provisions of this Section 511
          conflict with any other provisions of this Trust Agreement, the
          provisions of this Section 511 shall control; and

                                       25
<PAGE>

               (iv) the rights of the Owners of the Book-Entry Preferred
          Securities Certificates shall be exercised only through the Clearing
          Agency and shall be limited to those established by law and agreements
          between such Owners and the Clearing Agency and/or the Clearing Agency
          Participants. Pursuant to the Certificate Depository Agreement, unless
          and until Definitive Preferred Securities Certificates are issued
          pursuant to Section 513, the initial Clearing Agency will make
          book-entry transfers among the Clearing Agency Participants and will
          receive and transmit payments on the Preferred Securities to such
          Clearing Agency Participants. Any Clearing Agency designated pursuant
          hereto will not be deemed an agent of the Trustees for any purpose.

     (b)  Upon the execution and delivery of this Trust Agreement, a single
Common Securities Certificate representing the Common Securities shall be issued
to the Depositor in the form of a definitive Common Securities Certificate. Upon
exercise of the Underwriters' Over-Allotment Option, an additional, single
Common Securities Certificate representing the Common Securities shall be issued
to the Depositor in the form of a definitive Common Securities Certificate.

     SECTION 512. NOTICES TO CLEARING AGENCY. To the extent that a notice or
other communication to the Owners is required under this Trust Agreement, unless
and until Definitive Preferred Securities Certificates shall have been issued to
Owners pursuant to Section 513, the Trustees shall give all such notices and
communications specified herein to be given to Owners to the Clearing Agency,
and shall have no obligations to the Owners.

     SECTION 513. DEFINITIVE PREFERRED SECURITIES CERTIFICATES. If (a) the
Depositor advises the Trustees in writing that the Clearing Agency is no longer
willing or able to properly discharge its responsibilities with respect to the
Preferred Securities Certificates, and the Depositor is unable to locate a
qualified successor, (b) the Depositor at its option advises the Trustees in
writing that it elects to terminate the book-entry system through the Clearing
Agency, or (c) after the occurrence of a Debenture Event of Default, Owners of
Preferred Securities Certificates representing beneficial interests aggregating
at least a majority of the Liquidation Amount advise the Property Trustee in
writing that the continuation of a book-entry system through the Clearing Agency
is no longer in the best interests of the Owners of Preferred Securities
Certificates, then the Property Trustee shall notify the Clearing Agency, and
the Clearing Agency shall notify all Owners of Preferred Securities
Certificates, of the occurrence of any such event and of the availability of the
Definitive Preferred Securities Certificates to Owners of such class or classes,
as applicable, requesting the same. Upon surrender to the Property Trustee of
the typewritten Preferred Securities Certificate or Certificates representing
the Book-Entry Preferred Securities Certificates by the Clearing Agency,
accompanied by registration instructions, the Administrative Trustees, or any
one of them, shall execute the Definitive Preferred Securities Certificates in
accordance with the instructions of the Clearing Agency. Neither the Securities
Registrar nor the Trustees shall be liable for any delay in

                                       26
<PAGE>

delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Preferred Securities Certificates, the Trustees shall recognize the Holders of
the Definitive Preferred Securities Certificates as Security holders. The
Definitive Preferred Securities Certificates shall be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrative Trustees, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

     SECTION 514. RIGHTS OF SECURITY HOLDERS.

     (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 Security holders 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 will 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 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 Junior Subordinated
Debentures fail to declare the principal of all of the Junior Subordinated
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 Junior Subordinated Debentures shall become immediately due and
payable, provided that the payment of principal and interest on such Junior
Subordinated Debentures shall remain subordinated to the extent provided in the
Indenture. If, as a result of a Debenture Event of Default, the Debenture
Trustee or the holders of not less than 25% in aggregate outstanding principal
amount of the Junior Subordinated Debentures have declared the Junior
Subordinated Debentures due and payable and if such default has been cured and a
sum sufficient to pay all matured installments due (otherwise than by
acceleration) under the Junior Subordinated Debentures has been deposited with
the Debenture Trustee, then (if the holders of not less than a majority in
aggregate outstanding principal amount of Junior Subordinated Debentures have
not annulled such declaration and waived such default) the Holders of a majority
in aggregate Liquidation Amount of the Preferred Securities may annul such
declaration and waive such default.

                                       27
<PAGE>

     (c)  For so long as any Preferred Securities remain outstanding, upon a
Debenture Event of Default arising from the failure to pay interest or principal
on the Junior Subordinated Debentures, the Holders of any 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 Junior Subordinated Debentures having a
principal amount equal to the Liquidation Amount of the Preferred Securities of
such Holders.

                                   ARTICLE VI.

                   ACTS OF SECURITY HOLDERS; MEETINGS; VOTING

     SECTION 601. LIMITATIONS ON VOTING RIGHTS.

     (a)  Except as provided in this Section, in Sections 514, 810 and 1002 and
in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Security holders from time to time as partners or members of an association.

     (b)  So long as any Junior Subordinated Debentures are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on the Debenture Trustee with respect to
such Junior Subordinated Debentures, (ii) waive any past default which is
waivable under Article Seven of the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Junior Subordinated
Debentures shall be due and payable or (iv) consent to any amendment,
modification or termination of the Indenture or the Junior Subordinated
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 Outstanding Preferred Securities; provided, however,
that where a consent under the Indenture would require the consent of each
holder of outstanding Junior Subordinated Debentures affected thereby, no such
consent shall be given by the Property Trustee without the prior written consent
of each Holder of Preferred Securities. The Trustees shall not revoke any action
previously authorized or approved by a vote of the Holders of the Outstanding
Preferred Securities, except by a subsequent vote of the Holders of the
Outstanding Preferred 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 Junior Subordinated Debentures. In
addition to obtaining the foregoing approvals of the Holders of the Preferred
Securities, prior to taking any of the foregoing actions, the Trustees shall, at
the expense of the Depositor, obtain an Opinion of Counsel experienced in such
matters to the effect that the Trust will continue to be classified as a

                                       28
<PAGE>

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
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in Liquidation
Amount of the Outstanding Preferred Securities. 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.

     SECTION 602. NOTICE OF MEETINGS. Notice of all meetings of the Holders of
Preferred Securities, stating the time, place and purpose of the meeting, shall
be given by the Property Trustee pursuant to Section 1008 to each Holder of
Preferred Securities of record, at such Securityholder's 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 HOLDERS OF PREFERRED SECURITIES. No annual meeting
of Security holders is required to be held. The Administrative Trustees,
however, shall call a meeting of Security holders to vote on any matter upon the
written request of the Holders 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
Holders of the Preferred Securities to vote on any matters as to which the
Holders of the Preferred Securities are entitled to vote.

     Holders of at least 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 such Security holders.

     If a quorum is present at a meeting, an affirmative vote by the Holders 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
Holders of Preferred Securities of record present, either in person or by proxy,
at such meeting shall constitute the action of the Holders of the Preferred
Securities, unless this Trust Agreement requires a greater number of affirmative
votes.

                                       29
<PAGE>

     SECTION 604. VOTING RIGHTS. Security holders shall be entitled to one vote
for each $10 of Liquidation Amount represented by their Trust Securities in
respect of any matter as to which such Security holders are entitled to vote.

     SECTION 605. PROXIES, ETC. At any meeting of Security holders, 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. When Trust Securities are held jointly
by several persons, any one of them may vote at any meeting in person or by
proxy in respect of such Trust Securities, but if more than one of them shall be
present at such meeting in person or by proxy, and such joint owners or their
proxies so present disagree as to any vote to be cast, such vote shall not be
received in respect of such Trust Securities. A proxy purporting to be executed
by or on behalf of a Securityholder shall be deemed valid unless challenged at
or prior to its exercise, and, the burden of proving invalidity shall rest on
the challenger. No proxy shall be valid more than three years after its date of
execution.

     SECTION 606. SECURITYHOLDER ACTION BY WRITTEN CONSENT. Any action which may
be taken by Security holders at a meeting may be taken without a meeting if
Security holders holding more than a majority of all 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 (based upon their aggregate Liquidation Amount).

     SECTION 607. RECORD DATE FOR VOTING AND OTHER PURPOSES. For the purposes of
determining the Security holders who are entitled to notice of and to vote at
any meeting or by written consent, or to participate in any distribution on the
Trust Securities in respect of which a record date is not otherwise provided for
in this Trust Agreement, or for the purpose of any other action, the
Administrative Trustees may from time to time fix a date, not more than 90 days
prior to the date of any meeting of Security holders or the payment of any
distribution or other action, as the case may be, as a record date for the
determination of the identity of the Security holders of record for such
purposes.

     SECTION 608. ACTS OF SECURITY HOLDERS. 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 Security holders or Owners may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Security holders or Owners 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 Security holders or Owners signing such instrument or instruments.
Proof of execution of any such instrument or of a writing

                                       30
<PAGE>

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.

     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 such signer's
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of such signer's authority. The fact and date of the execution
of any such instrument or writing, or the authority of the Person executing the
same, may also be proved in any other manner which any Trustee receiving the
same deems sufficient.

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

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

     Without limiting the foregoing, a Securityholder entitled hereunder to take
any action hereunder with regard to any particular Trust Security may do so with
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.

     A Holder of Preferred Securities 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 by Security holders during normal business hours for any
purpose reasonably related to such Securityholder's interest as a
Securityholder.

                                  ARTICLE VIII.

                                  THE 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 such
Trustee's acts or omissions hereunder except as a result of such Trustee's 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. 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
Security holders, 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 Security holders to

                                       34
<PAGE>

replace such other duties and liabilities of the Delaware Trustee and the
Administrative Trustees.

     (b)  All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the Property Trustee or a Paying
Agent to make payments in accordance with the terms hereof. Each Securityholder,
by such Securityholder's acceptance of a Trust Security, agrees that such
Securityholder will look solely to the revenue and proceeds from the Trust
Property to the extent legally available for distribution to such Securityholder
as herein provided and that the Trustees are not personally liable to such
Securityholder 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.

     (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 Junior Subordinated
     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

                                       35
<PAGE>

          (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 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 Security holders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. For purposes of
this Section 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 Security holders in
the manner and to the extent provided in Section 1008, notice of the Depositor's
election to begin or further extend an Extension Period on the Junior
Subordinated Debentures (unless such election shall have been revoked) within
the time specified for transmitting such notice to the holders of the Junior
Subordinated Debentures pursuant to the Indenture as originally executed.

     (c)  In the event the Depositor elects to accelerate the Maturity Date in
accordance with Section 2.2 of the Indenture, the Property Trustee shall give
notice to each Holder of Trust Securities of the acceleration of the Maturity
Date and the Accelerated Maturity Date not later than five Business Days after
the Property Trustee receives the notice provided in Section 2.2(c) of the
Indenture.

     SECTION 803. CERTAIN RIGHTS OF 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 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
Holders of the Preferred Securities 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

                                       36
<PAGE>

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 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
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 Security holders, 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 any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

     (f)  the Property Trustee may consult with counsel of its choice 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 or
direction of any of the Security holders pursuant to this Trust Agreement,
unless such Security holders shall have offered to the Property Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred by it in compliance with such request or direction;

     (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 one or more Security holders, but the
Property Trustee may make such further inquiry or investigation into such facts
or matters as it may see fit;

                                       37
<PAGE>

     (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 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 (as such) shall not be
accountable for the use or application by the Depositor of the proceeds of the
Junior Subordinated 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 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);

                                       38
<PAGE>

     (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, claim, 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 cost or expense 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
cost or expense as may be attributable to its, his or her gross negligence, bad
faith or willful misconduct).

     No Trustee may claim any Lien 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, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Property Trustee with respect to the Trust
Securities shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

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

     (c)  There shall at all times be a Delaware Trustee with respect to the
Trust Securities. The Delaware Trustee shall either be (i) a natural person who
is at least 21 years of age and a resident of the State of Delaware or (ii) a
legal entity with its principal

                                       39
<PAGE>

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. Unless an Event of Default
shall have occurred and be continuing, at any time or times, for the purpose of
meeting the legal requirements of the Trust Indenture Act or of any jurisdiction
in which any part of the Trust Property may at the time be located, the
Depositor and the Administrative Trustees shall have power to appoint, and upon
the written request of the Property Trustee, the Depositor and the
Administrative Trustees 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. In case a
Debenture Event of Default has occurred and is continuing, the Property Trustee
alone shall have power to make such appointment. Any co-trustee or separate
trustee appointed pursuant to this Section shall either be (i) a natural person
who is at least 21 years of age and a resident of the United States or (ii) a
legal entity with its principal place of business in the United States that
shall act through one or more persons authorized to bind such entity.

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

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

     (a)  The Trust Securities shall be executed and delivered and all rights,
powers, duties and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder, shall be exercised,
solely by such Trustees and not by such co-trustee or separate trustee.

     (b)  The rights, powers, duties and obligations hereby conferred or imposed
upon the Property Trustee in respect of any property covered by such appointment
shall be

                                       40
<PAGE>

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

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

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

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

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

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

     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 Security holders. 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 Trustee with respect
to the Trust Securities.

     Unless a Debenture Event of Default shall have occurred and be continuing,
any Trustee may be removed at any time by Act of the Holder of the Common
Securities. 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 Act of the Holders

                                       41
<PAGE>

of a majority in Liquidation Amount of the Preferred Securities, delivered to
such Relevant Trustee (in its individual capacity and on behalf of the Trust).
An Administrative Trustee may be removed by the Holder of the Common Securities
at any time. In no event will the Holders of the Preferred Securities have the
right to vote to appoint, remove or replace the Administrative Trustees.

     If the Relevant Trustee shall resign, be removed or become incapable of
acting as Trustee, or if a vacancy shall occur in the office of such Relevant
Trustee for any cause, at a time when no Debenture Event of Default shall have
occurred and be continuing, the Holder of the Common Securities, by Act of the
Holder of the Common Securities delivered to the retiring Relevant 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 Holders of
the Preferred Securities by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities then Outstanding delivered to the retiring
Relevant Trustee, shall promptly appoint a successor 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 Administrative
Trustee, at a time when a Debenture Event of Default shall have occurred and be
continuing, the Holder of the Common Securities, by Act of the Holder of the
Common Securities 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 Trustee with respect to the Trust Securities shall have
been so appointed by the Holder of the Common Securities or the Holders of the
Preferred Securities and accepted appointment in the manner required by Section
811, any Securityholder who has been a Securityholder for at least six months
may, on behalf of such Securityholder and all others similarly situated,
petition a court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Trust Securities.

     The Property Trustee shall give notice of each resignation and each removal
of a Relevant Trustee and each appointment of a successor Trustee to all
Security holders in the manner provided in Section 1008 and shall give notice to
the Depositor. Each notice shall include the name of the successor Trustee and
the address of its Corporate Trust office if it is the Property Trustee.

     Subject to 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 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

                                       42
<PAGE>

requirement for Administrative Trustees or the Delaware Trustee, as the case may
be, set forth in Section 807).

     SECTION 811. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. In case of the
appointment hereunder of a successor Trustee with respect to the Trust
Securities and the Trust, the retiring Relevant Trustee and each successor
Trustee with respect to the Trust Securities shall execute and deliver an
instrument hereto wherein each successor 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 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 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 Trustee such retiring Relevant Trustee shall duly assign, transfer and
deliver to such successor Trustee all Trust Property, all proceeds thereof and
money held by such retiring Relevant Trustee hereunder with respect to the Trust
Securities and the Trust.

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

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

     SECTION 812. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.
Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which such Relevant Trustee shall be a party, or
any 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, 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 DEPOSITOR OR 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 Junior
Subordinated 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 Trust (or any
such other obligor).

     SECTION 814. REPORTS BY PROPERTY TRUSTEE.

     (a)  Not later than January 31 of each year commencing with January 31,
2002, the Property Trustee shall transmit to all Security holders in accordance
with Section 1008, and to the Depositor, a brief report dated as of the
preceding December 31 with respect to:

          (i)  its eligibility under Section 807 or, in lieu thereof, if to the
     best of its knowledge it has continued to be eligible under said Section, a
     written statement to such effect; and

          (ii) any change in the property and funds in its possession as
     Property Trustee since the date of its last report and any action taken by
     the Property Trustee in the performance of its duties hereunder which it
     has not previously reported and which in its opinion materially affects the
     Trust Securities.

     (b)  In addition the Property Trustee shall transmit to Security holders
such reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.

     (c)  A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with each national securities exchange
or other organization upon which the Trust Securities may be listed, with the
Commission and with 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 the 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 the
Common Securities by written instrument may increase or decrease the number of
Administrative Trustees. The Property Trustee and the Delaware Trustee may be
the same Person.

                                       44
<PAGE>

     (b)  If a Trustee ceases to hold office for any reason and the number of
Administrative Trustees is not reduced pursuant to Section 817(a), or if the
number of 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.

     (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 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)(i); 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.

events is an "Early Termination Event":

                                       45
<PAGE>

     (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) to dissolve the Trust and distribute the Junior Subordinated
Debentures to Security holders in exchange for the Preferred Securities in
accordance with Section 904;

     (c)  the redemption of all of the Preferred Securities in connection with
the redemption of all of the Junior Subordinated Debentures; and

     (d)  an order for dissolution of the Trust shall have been entered 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 Security holders 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 Security holders, and (d) the filing of a
certificate of cancellation by the Administrative Trustee under the Delaware
Business 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 Junior
Subordinated 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 will no longer be deemed to be Outstanding and any Trust
     Securities Certificates not surrendered for exchange will be deemed to
     represent a Like Amount of Junior Subordinated Debentures; and

          (iii) provide such information with respect to the mechanics by which
     Holders may exchange Trust Securities certificates for Junior Subordinated

                                       46
<PAGE>

     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 Junior Subordinated Debentures
to Security holders, 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 Junior Subordinated Debentures in
exchange for the Outstanding Trust Securities Certificates.

     (c)  Except where Section 902(c) or 904(d) applies, after the Liquidation
Date, (i) the Trust Securities will no longer be deemed to be Outstanding, (ii)
certificates (or, at the election of the Depositor a Global Subordinated
Debenture, subject to the provisions of the Indenture) representing a Like
Amount of Junior Subordinated Debentures will be issued to 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 reasonable efforts to have the Junior Subordinated Debentures listed on
the American Stock Exchange or on such other securities exchange, quotation
system or other organization as the Preferred Securities may then be listed or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Junior Subordinated Debentures,
accruing interest at the rate provided for in the Junior Subordinated 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 will
be made to Holders of Trust Securities Certificates with respect to such Junior
Subordinated Debentures) and (v) all rights of Security holders holding Trust
Securities will cease, except the right of such Security holders to receive
Junior Subordinated Debentures upon surrender of 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 Junior Subordinated
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, Security holders will be entitled
to receive out of the assets of the Trust available for distribution to Security
holders, 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). The Holder of the Common Securities will

                                       47
<PAGE>

be entitled to receive Liquidation Distributions upon any such dissolution,
winding-up or termination pro rata (determined as aforesaid) with Holders of
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 (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities") so long as the Successor Securities rank
the same as the Preferred Securities rank in priority with respect to
distributions and payments upon liquidation, redemption and otherwise, (ii) the
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 Junior Subordinated Debentures, (iii) 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, (iv)
such successor entity has a purpose identical to that of the Trust, (v) the
Successor Securities will be listed or traded on any national securities
exchange or other organization on which the Preferred Securities may then be
listed, (vi) prior to such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, the Depositor has received an Opinion of Counsel
experienced in such matters to the effect that (a) 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 (b)
following such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease, neither the Trust nor such successor entity will be required
to register as an "investment company" under the Investment Company Act and
(vii) the Depositor or any permitted successor or designee owns all of the
Common Securities of the successor entity and guarantees the obligations of the
successor entity under the Successor Securities at least to the extent provided
by the Guarantee.

     Notwithstanding the foregoing, the Trust shall not, except with the consent
of Holders of 100% in Liquidation Amount of the Preferred Securities,
consolidate, amalgamate, merge with or into, 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,

                                       48
<PAGE>

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.

                                   ARTICLE X.

                            MISCELLANEOUS PROVISIONS

     SECTION 1001. LIMITATION OF RIGHTS OF SECURITY HOLDERS. The death or
incapacity of any Person having an interest, beneficial or otherwise, in Trust
Securities shall not operate to terminate this Trust Agreement, nor entitle the
legal representatives or heirs of 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.

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, or (iii) to modify, eliminate or add to any provisions
of this Trust Agreement to such extent as shall be necessary to ensure that the
Trust will be classified for United States federal income tax purposes as a
grantor trust at all times that any Trust Securities are Outstanding or to
ensure that the Trust will not be required to register as an "investment
company" under the Investment Company Act; 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 any amendments of this Trust Agreement
shall become effective when notice thereof is given to the Security holders.

     (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 Security holders 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 will 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.

     (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

                                       49
<PAGE>

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 for the enforcement of
any such payment on or after such date; notwithstanding any other provision
herein, without the unanimous consent of the Security holders (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 is in compliance
with this Trust Agreement.

     SECTION 1003. SEPARABILITY. In case any provision in this Trust Agreement
or in the Trust Securities Certificates shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

     SECTION 1004. GOVERNING LAW. THIS TRUST AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF EACH OF THE SECURITY HOLDERS, THE TRUST AND THE TRUSTEES WITH
RESPECT TO THIS TRUST AGREEMENT AND THE TRUST SECURITIES SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF DELAWARE (WITHOUT
REGARD TO CONFLICT OF LAWS PRINCIPLES).

     SECTION 1005. PAYMENTS DUE ON NON-BUSINESS DAY. If the date fixed for any
payment on any Trust Security shall be a day that is not a Business Day, then
such payment need not be made on such date but may be made on the next
succeeding day which is a Business Day (except as otherwise provided in Sections
401(a) and 402(d)), 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.

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 Twelve of the Indenture and pursuant to which the
assignee agrees in writing to perform the Depositor's obligations hereunder, the

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
