Common Securities and the consequences thereof until all Trust Enforcement
Events with respect to the Capital Securities have been cured, waived or

the right to direct the Property Trustee in accordance with the terms of the
Securities. The foregoing provisions of this Section 2.6(b) shall be in lieu of
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby
expressly excluded from this Trust Agreement and the Securities, as permitted by
the Trust Indenture Act. Subject to the foregoing provisions of this Section
2.6(b), upon such cure, waiver or other elimination, any such default shall
cease to exist and any Trust Enforcement Event with respect to the Common
Securities arising therefrom shall be deemed to have been cured for every
purpose of this Trust Agreement, but no such waiver shall extend to any
subsequent or other Trust Enforcement Event with respect to the Common
Securities or impair any right consequent thereon.

                  (c)      A waiver of an Indenture Event of Default by the
Property Trustee at the direction of the Holders of the Capital Securities
constitutes a waiver of the corresponding Trust Enforcement Event with respect
to the Capital Securities under this Trust Agreement. The foregoing provisions
of this Section 2.6(c) shall be in lieu of Section 316(a)(1)(B) of the Trust
Indenture Act and such Section 316(a)(1)(B) of the Trust Indenture Act is hereby
expressly excluded from this Trust Agreement and the Securities, as permitted by
the Trust Indenture Act.

         SECTION 2.7. Trust Enforcement Event; Notice.

                  (a)      The Property Trustee shall, within 90 days after the
occurrence of a Trust Enforcement Event actually known to a Responsible Officer
of the Property Trustee, transmit by mail, first class postage prepaid, to the
Holders of the Securities, notices of all such defaults with respect to the
Securities, unless such defaults have been cured before the giving of such
notice (the term "defaults" for the purposes of this Section 2.7(a) being hereby
defined to be an Indenture Event of Default, not including any periods of grace
provided for therein and irrespective of the giving of any notice provided
therein); provided that, except for a default in the payment of principal of (or
premium, if any) or interest on any of the Debentures, the Property Trustee
shall be protected fully in withholding such notice if and so long as a
Responsible Officer of the Property Trustee in good faith determines that the
withholding of such notice is in the interests of the Holders of the Securities.

                  (b)      The Property Trustee shall not be deemed to have
knowledge of any default except:

                           (i)      a default under Sections 5.1(1) and 5.1(2)
                  of the Indenture; or

                           (ii)     any default as to which the Property Trustee
                  shall have received written notice or of which a Responsible
                  Officer of the Property Trustee charged with the
                  administration of this Trust Agreement shall have actual
                  knowledge.

         Subject to the limitations provided in this Trust Agreement and to the
specific duties of the Property Trustee, the Administrative Trustees shall have
exclusive authority to carry out the purposes of the Trust. An action taken by
the Administrative Trustees in accordance with their powers shall constitute the
act of and serve to bind the Trust and an action taken by the Property Trustee
on behalf of the Trust in accordance with its powers shall constitute the act of
and serve to bind the Trust. In dealing with the Trustees acting on behalf of
the Trust, no Person shall be required to inquire into the authority of the
Trustees to bind the Trust. Persons dealing with the Trust are entitled to rely
conclusively on the power and authority of the Trustees as set forth in this
Trust Agreement.

                           (i)      invest any proceeds received by the Trust
                  from holding the Debentures, but shall distribute all such

                           (vi)     possess any power or otherwise act in such a
                  way as to vary the terms of the Securities in any way
                  whatsoever (except to the extent expressly authorized in this

                           (vii)    issue any securities or other evidences of

                  or termination of the Indenture or the Debentures where such
                  consent shall be required unless the Trust shall have received
                  an opinion of counsel to the effect that such modification
                  will not cause more than an insubstantial risk that the Trust
                  will be deemed an Investment Company required to be registered
                  under the Investment Company Act, or the Trust will be

                  (a)      The legal title to the Debentures shall be owned by
and held of record in the name of the Property Trustee for the benefit of the
Trust and the Holders of the Securities. The right, title and interest of the
Property Trustee to the Debentures shall vest automatically in each Person who
may hereafter be appointed as Property Trustee in accordance with Section 6.6.

conveyancing documents with regard to the Debentures have been executed and
delivered.

                  (b)      The Property Trustee shall not transfer its right,
title and interest in the Debentures to the Administrative Trustees or to the

                                       16
<PAGE>   24
                           (i)      establish and maintain a segregated
                  non-interest bearing trust account (the "Property Account") in
                  the name of and under the exclusive control of the Property
                  Trustee on behalf of the Holders of the Securities and, upon
                  the receipt of payments of funds made in respect of the
                  Debentures held by the Property Trustee, deposit such funds
                  into the Property Account and make payments to the Holders of
                  the Capital Securities and Holders of the Common Securities
                  from the Property Account in accordance with Section 7.2.
                  Funds in the Property Account shall be held uninvested until
                  disbursed in accordance with this Trust Agreement. The
                  Property Account shall be an account that is maintained with a
                  banking institution the rating on whose long-term unsecured
                  indebtedness is at least equal to the rating assigned to the
                  Capital Securities by a "nationally recognized statistical
                  rating organization", within the meaning of Rule 436(g)(2)
                  under the Securities Act;

                           (ii)     engage in such ministerial activities as
                  shall be necessary or appropriate to effect the redemption of
                  the Capital Securities and the Common Securities to the extent
                  the Debentures are redeemed or mature; and

                           (iii)    upon written notice of distribution issued
                  by the Administrative Trustees in accordance with the terms of
                  the Securities, engage in such ministerial activities as so
                  directed and as shall be necessary or appropriate to effect
                  the distribution of the Debentures to Holders of Securities
                  upon the occurrence of a Special Event.

                  (d)      The Property Trustee shall take all actions and
perform such duties as may be specifically required of the Property Trustee
pursuant to the terms of this Trust Agreement and the Securities.

                  (e)      The Property Trustee shall take any Legal Action
which arises out of or in connection with a Trust Enforcement Event of which a
Responsible Officer of the Property Trustee has actual knowledge or the Property
Trustee's duties and obligations under this Trust Agreement or the Trust
Indenture Act; provided, however, that if a Trust Enforcement Event has occurred
and is continuing and such event is attributable to the failure of the Debenture
Issuer to pay interest, principal or other required payments on the Debentures
on the date such interest, principal or other required payments are otherwise
payable (or in the case of redemption, on the redemption date), then a Holder of
Capital Securities may directly institute a proceeding against the Debenture
Issuer for enforcement of payment to such Holder of the principal of or interest
on Debentures having a principal amount equal to the aggregate liquidation
amount of the Capital Securities of such Holder (a "Direct Action") on or after
the respective due date specified in the Debentures. Notwithstanding anything to
the contrary in this Trust Agreement or the Indenture, the Debenture Issuer
shall have the right to set-off any payment it is otherwise required to make
under the Indenture in respect of any Capital Security to the extent the
Debenture Issuer has heretofore made, or is currently on the date of such
payment making, a payment under the Guarantee relating to such Capital Security
or under Section 5.8 of the Indenture.

                  (f)      The Property Trustee shall continue to serve as a
Trustee until either:


                                       17
<PAGE>   25
                           (i)      the Trust has been completely liquidated and
                  the proceeds of the liquidation distributed to the Holders of
                  Securities pursuant to the terms of the Securities; or

                           (ii)     a Successor Property Trustee has been
                  appointed and has accepted that appointment in accordance with
                  Section 6.6.

                  (g)      The Property Trustee shall have the legal power to
exercise all of the rights, powers and privileges of a holder of Debentures
under the Indenture and, if a Trust Enforcement Event actually known to a
Responsible Officer of the Property Trustee occurs and is continuing, the
Property Trustee shall, for the benefit of Holders of the Securities, enforce
its rights as holder of the Debentures subject to the rights of the Holders
pursuant to the terms of such Securities.

                  (h)      The Property Trustee may authorize one or more
Persons (each, a "Paying Agent") to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all Securities and
any such Paying Agent shall comply with Section 317(b) of the Trust Indenture
Act. Any Paying Agent may be removed by the Property Trustee at any time and a
successor Paying Agent or additional Paying Agents may be appointed at any time
by the Property Trustee.

                  (i)      Subject to this Section 3.8, the Property Trustee
shall have none of the duties, liabilities, powers or the authority of the
Administrative Trustees set forth in Section 3.6.

         The Property Trustee shall exercise the powers set forth in this
Section 3.8 in a manner that is consistent with the purposes and functions of
the Trust set out in Section 3.3, and the Property Trustee shall have no power
to, and shall not, take any action that is inconsistent with the purposes and
functions of the Trust set out in Section 3.3.

         SECTION 3.9. Certain Duties and Responsibilities of the Property
Trustee.

                  (a)      The Property Trustee, before the occurrence of any
Trust Enforcement Event and after the curing of all Trust Enforcement Events
that may have occurred, shall undertake to perform only such duties as are
specifically set forth in this Trust Agreement and no implied covenants shall be
read into this Trust Agreement against the Property Trustee. In case a Trust
Enforcement Event has occurred (that has not been cured or waived pursuant to
Section 2.6) of which a Responsible Officer of the Property Trustee has actual
knowledge, the Property Trustee shall exercise such of the rights and powers
vested in it by this Trust Agreement, and use the same degree of care and skill
in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

                  (b)      No provision of this 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)      prior to the occurrence of a Trust
                  Enforcement Event and after the curing or waiving of all such
                  Trust Enforcement Events that may have occurred:

                  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

                  the extent otherwise required by law; and

                  Administrative Trustees or the Sponsor with their respective
                  duties under this Trust Agreement, nor shall the Property
                  Trustee be liable for any default or misconduct of the
                  Administrative Trustees or the Sponsor.

                  shall be sufficiently evidenced by an Officers' Certificate;

                           (iii)    whenever in the administration of this Trust

                  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 Sponsor or the

                  filing under tax or securities laws) or any rerecording,
                  refiling or registration thereof;

                  opinion of such counsel and experts with respect to legal
                  matters or advice within the scope of such experts' area of

                  be full and complete authorization and protection in respect
                  of any action taken, suffered or omitted by it hereunder in

                  counsel may be counsel to the Sponsor or any of its
                  Affiliates, and may include any of its employees. The Property
                  Trustee shall have the right at any time to seek instructions

                  obligation to exercise any of the rights or powers vested in
                  it by this Trust Agreement at the request or direction of any
                  Holder, unless such Holder shall have provided to the Property
                  Trustee security and indemnity, reasonably satisfactory to the
                  Property Trustee, against the costs, expenses (including
                  reasonable attorneys' fees and expenses and the expenses of
                  the Property Trustee's agents, nominees or custodians) and
                  liabilities that might be incurred by it in complying with
                  such request or direction, including such reasonable advances
                  as may be requested by the Property Trustee; provided that,
                  nothing contained in this Section 3.10(a) shall be taken to
                  relieve the Property Trustee, upon the occurrence of a Trust
                  Enforcement Event, of its obligation to exercise the rights
                  and powers vested in it by this Trust Agreement;

                  or document, but the Property Trustee, in its discretion, may
                  make such further inquiry or investigation into such facts or

                  for any misconduct or negligence on the part of any agent or
                  attorney appointed with due care by it hereunder, provided

                  Property Trustee to so act or as to its compliance with any of
                  the terms and provisions of this Trust Agreement, both of
                  which shall be conclusively evidenced by the Property
                  Trustee's or its agent's taking such action;

                           (x)      whenever in the administration of this Trust
                  Agreement the Property Trustee shall deem it desirable to

                  right or taking any other action hereunder, the Property
                  Trustee (i) may request instructions from the Holders of the

                  from enforcing such remedy or right or taking such other
                  action until such instructions are received, and (iii) shall

                  accordance with such instructions;

                           (xi)     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

                  reasonably believed by it to be authorized or within the
                  discretion, rights or powers conferred upon it by this Trust
                  Agreement;

                           (xiii)   without prejudice to any other rights

                  the Property Trustee incurs expenses or renders services in
                  connection with a bankruptcy, such expenses (including the
                  fees and expenses of its counsel) and the compensation for
                  such services are intended to constitute expenses of
                  administration under any bankruptcy law or law relating to
                  creditors rights generally; and

                           (xiv)    the Property Trustee shall not be charged
                  with knowledge of a Trust Enforcement Event unless a
                  Responsible Officer of the Property Trustee obtains actual
                  knowledge of such event or the Property Trustee receives
                  written notice of such event from Holders holding more than a
                  Majority in Liquidation Amount of the Capital Securities;

                  (b)      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.

                                             obligations of the Trust with
                                             respect to the Securities; or

                                             substantially the same terms as the

                                             as the Capital Securities rank in
                                             priority with respect to
                                             Distributions and payments upon

                  replacement, conveyance, transfer or lease does not cause the
                  Capital Securities (including any Successor Securities) to be
                  downgraded by any nationally recognized statistical rating
                  organization;

                                             amalgamation, replacement,
                                             conveyance, transfer or lease does
                                             not adversely affect the rights,
                                             preferences and privileges of the
                                             Holders of the Capital Securities
                                             (including any Successor

                                             respect;

                                    b.       following such merger,
                                             consolidation, amalgamation,
                                             replacement, conveyance, transfer
                                             or lease neither the Trust nor the
                                             Successor Entity will be required
                                             to register as an Investment
                                             Company; and

                                    c.       following such merger,
                                             consolidation, amalgamation or
                                             replacement, the Trust (or the
                                             Successor Entity) will continue to
                                             be classified as a grantor trust
                                             for United States federal income
                                             tax purposes;

                           (viii)   the Sponsor or any permitted successor or
                  assignee owns all of the common securities and guarantees the
                  obligations of such Successor Entity under the Successor
                  Securities at least to the extent provided by the Securities
                  Guarantee and such Successor Entity expressly assumes all of
                  the obligations of the Trust with respect to the Trustees.

                  (c)      Notwithstanding Section 3.15(b), the Trust shall not,
except with the consent of Holders of 100% in aggregate liquidation amount of
the 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 entity or permit any other entity to consolidate,


                                       24
<PAGE>   32
amalgamate, merge with or into, or replace it, if such consolidation,
amalgamation, merger, replacement, conveyance, transfer or lease would cause the
Trust or Successor Entity to be classified as other than a grantor trust for
United States federal income tax purposes and each Holder of the Securities not
to be treated as owning an undivided interest in the Debentures.

         SECTION 3.16. Property Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Trust or any other obligor upon the
Securities or the property of the Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Securities shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Property Trustee shall
have made any demand on the Trust for the payment of any past due Distributions)
shall be entitled and empowered, to the fullest extent permitted by law, by
intervention in such proceeding or otherwise:

                  (a)      to file and prove a claim for the whole amount of any
         Distributions owing and unpaid in respect of the Securities (or, if the
         Securities are original issue discount Securities, such portion of the
         liquidation amount as may be specified in the terms of such Securities)
         and to file such other papers or documents as may be necessary or
         advisable in order to have the claims of the Property Trustee
         (including any claim for the reasonable compensation, expenses,
         disbursements and advances of the Property Trustee, its and counsel)
         and of the Holders allowed in such judicial proceeding, and

                  (b)      to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Property Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel, and any other amounts due the Property Trustee.

         Nothing herein contained shall be deemed to authorize the Property
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement adjustment or compensation affecting the
Securities or the rights of any Holder thereof or to authorize the Property
Trustee to vote in respect of the claim of any Holder in any such proceeding.

of the Investment Company Act, and (iv) to take no action which would be
reasonably likely to cause the Trust to be classified as other than a grantor
trust for United States federal income tax purposes.

acts as Delaware Trustee shall not be removed in accordance with Section 6.6(a)
until a successor Trustee possessing the qualifications to act as Delaware
Trustee under Sections 6.2 and 6.4 (a "Successor Delaware Trustee") has been
appointed and has accepted such appointment by


                                       29
<PAGE>   37
written instrument executed by such Successor Delaware Trustee and delivered to
the Administrative Trustees and the Sponsor.

                  (c)      A Trustee appointed to office shall hold office until
his or its successor shall have been appointed, until his death or its
dissolution or until his or its removal or resignation. Any Trustee may resign
from office (without need for prior or subsequent accounting) by an instrument
in writing signed by the Trustee and delivered to the Sponsor and the Trust,
which resignation shall take effect upon such delivery or upon such later date
as is specified therein; provided, however, that:

                           (i)      no such resignation of the Trustee that acts
                  as the Property Trustee shall be effective:

                                    a.       until a Successor Property Trustee
                                             has been appointed and has accepted
                                             such appointment by instrument
                                             executed by such Successor Property
                                             Trustee and delivered to the Trust,
                                             the Sponsor and the resigning
                                             Property Trustee; or

                                    b.       until the assets of the Trust have
                                             been completely liquidated and the
                                             proceeds thereof distributed to the
                                             holders of the Securities; and

                           (ii)     no such resignation of the Trustee that acts
                  as the Delaware Trustee shall be effective until a Successor
                  Delaware Trustee has been appointed and has accepted such
                  appointment by instrument executed by such Successor Delaware
                  Trustee and delivered to the Trust, the Sponsor and the
                  resigning Delaware Trustee.

                  (d)      The Holders of the Common Securities shall use their
best efforts to promptly appoint a Successor Delaware Trustee or Successor
Property Trustee, as the case may be, if the Property Trustee or the Delaware
Trustee delivers an instrument of resignation in accordance with this Section
6.6.

                  (e)      If no Successor Property Trustee or Successor
Delaware Trustee, as the case may be, shall have been appointed and accepted
appointment as provided in this Section 6.6 within 60 days after delivery to the
Sponsor and the Trust of an instrument of resignation or removal, the resigning
or removed Property Trustee or Delaware Trustee, as applicable, may petition any
court of competent jurisdiction in the U.S. for appointment of a Successor
Property Trustee or Successor Delaware Trustee, as applicable. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper, appoint
a Successor Property Trustee or Successor Delaware Trustee, as the case may be.

                  (f)      No Property Trustee or Delaware Trustee shall be
liable for the acts or omissions to act of any Successor Property Trustee or
Successor Delaware Trustee, as the case may be.

         SECTION 6.7. Vacancies among Trustees.

         If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 6.1, or if the number of Trustees is
increased pursuant to Section 6.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by the Administrative Trustees or, if
there are more than two, a majority of the Administrative Trustees shall be
conclusive evidence of the existence of such vacancy. The vacancy shall be
filled with a Trustee appointed in accordance with Section 6.6.

         SECTION 6.8. Effect of Vacancies.

         The death, resignation, retirement, removal, bankruptcy, dissolution,
liquidation, incompetence or incapacity to perform the duties of a Trustee shall
not operate to annul, dissolve or terminate the Trust. Whenever a vacancy in the
number of Administrative Trustees shall occur, until such vacancy is filled by
the appointment of an Administrative Trustee in accordance with Section 6.6, the
Administrative Trustees in office, regardless of their number, 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 6.9. Meetings.

         If there is more than one Administrative Trustee, meetings of the
Administrative Trustees shall be held from time to time upon the call of any
Administrative Trustee. Regular meetings of the Administrative Trustees may be
held at a time and place fixed by resolution of the Administrative Trustees.
Notice of any in-person meetings of the Administrative Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 48 hours before such meeting. Notice of
any telephonic meetings of the Administrative Trustees shall be hand delivered
or otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 24 hours before a meeting. Notices shall
contain a brief statement of the time, place and anticipated purposes of the
meeting. The presence (whether in person or by telephone) of an Administrative
Trustee at a meeting shall constitute a waiver of notice of such meeting except
where an Administrative Trustee attends a meeting for the express purpose of
objecting to the transaction of any activity on the ground that the meeting has
not been lawfully called or convened. Unless provided otherwise in this Trust
Agreement, any action of the Administrative Trustees may be taken at a meeting
by vote of a majority of the Administrative Trustees present (whether in person
or by telephone) and eligible to vote with respect to such matter, provided that
a Quorum is present, or without a meeting by the unanimous written consent of
the Administrative Trustees. In the event there is only one Administrative
Trustee, any and all action of such Administrative Trustee shall be evidenced by
a written consent of such Administrative Trustee.

         SECTION 6.10. Delegation of Power.

                  (a)      Any Administrative Trustee may, by power of attorney
consistent with applicable law, delegate to any natural person over the age of
21 his, her or its power for the purpose of executing any documents contemplated
in Section 3.6 or making any governmental


                                       31
<PAGE>   39
filing; provided that such person is a United States Person as defined in
Section 7701(a)(30) of the Code.

                  (b)      The Administrative Trustees shall have power to
delegate from time to time to such of their number or to officers of the Trust
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; provided, that such person is a United States Person as
defined in Section 7701(a)(30) of the Code.

         SECTION 6.11. Merger, Conversion, Consolidation or Succession to
Business.

         Any corporation 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 such Trustee may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of such Trustee shall be the successor of such Trustee hereunder,
provided such corporation 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.

                                    ARTICLE 7

                               TERMS OF SECURITIES

         SECTION 7.1. General Provisions Regarding Securities.

                  (a)      The Administrative Trustees shall on behalf of the
Trust issue one class of capital securities representing undivided beneficial
interests in the assets of the Trust and one class of common securities
representing undivided beneficial interests in the assets of the Trust.

                           (i)      Capital Securities. The Capital Securities
                  of the Trust have an aggregate liquidation amount with respect
                  to the assets of the Trust of up to ____________________
                  dollars ($______________) with respect to the closing of the
                  sale of Capital Securities on one or more occasions. The
                  Capital Securities are hereby designated for identification
                  purposes only as "_____% Trust Preferred Securities" (the
                  "Capital Securities"). The Capital Security Certificates
                  evidencing the Capital Securities shall be substantially in
                  the form of Exhibit A to this Trust Agreement, with such
                  changes and additions thereto or deletions therefrom as may be
                  required by ordinary usage, custom or practice or to conform
                  to the rules of any stock exchange on which the Capital
                  Securities are listed or quoted.

                           (ii)     Common Securities. The Common Securities of
                  the Trust have an aggregate liquidation amount with respect to
                  the assets of the Trust of up to _______________________
                  dollars ($______________) with respect to the


                                       32
<PAGE>   40
                  closing of the sale of Common Securities on one or more
                  occasions. The Common Securities are hereby designated for
                  identification purposes only as "_______% Common Securities"
                  (the "Common Securities" and, together with the Capital
                  Securities, the "Securities"). The Common Security
                  Certificates evidencing the Common Securities shall be
                  substantially in the form of Exhibit B to this Trust
                  Agreement, with such changes and additions thereto or
                  deletions therefrom as may be required by ordinary usage,
                  custom or practice.

                  (b)      Payment of Distributions on, and payment of the
Redemption Price upon a redemption of, the Capital Securities and the Common
Securities, as applicable, shall be made Pro Rata based on the liquidation
amount of such Capital Securities and Common Securities; provided, however, that
if on any date on which amounts payable on distribution or redemption, an
Indenture Event of Default shall have occurred and be continuing, no payment of
any Distribution on, or Redemption Price of, any of the Common Securities, and
no other payment on account of the redemption, liquidation or other acquisition
of such Common Securities, shall be made unless payment in full in cash of all
accumulated and unpaid Distributions on all of the outstanding Capital
Securities for all Distribution periods terminating on or prior thereto, or, in
the case of amounts payable on redemption, the full amount of the Redemption
Price for all of the outstanding Capital Securities then called for redemption,
shall have been made or provided for, and all funds available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions on, or the Redemption Price of, the Capital Securities then due
and payable. The Trust shall issue no securities or other interests in the
assets of the Trust other than the Capital Securities and the Common Securities.

                  (c)      The Certificates shall be signed on behalf of the
Trust by an Administrative Trustee. Such signature shall be the manual or
facsimile signature of any present or any future Administrative Trustee. In case
an Administrative Trustee of the Trust who shall have signed any of the
Certificates shall cease to be such Administrative Trustee before the
Certificates so signed shall be delivered by the Trust, such Certificates
nevertheless may be delivered as though the person who signed such Certificates
had not ceased to be such Administrative Trustee; and any Certificate may be
signed on behalf of the Trust by such persons who, at the actual date of
execution of such Certificate, shall be the Administrative Trustees of the
Trust, although at the date of the execution and delivery of the Trust Agreement
any such person was not such an Administrative Trustee. 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 their
execution thereof, and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements as the
Administrative Trustees may deem appropriate, or as may be required to comply
with any law or with any rule or regulation of any stock exchange on which
Securities may be listed, or to conform to usage.

         A Certificate representing Capital Securities shall not be valid until
authenticated by the manual signature of an authorized officer of the Property
Trustee. Such signature shall be conclusive evidence that such Certificate has
been authenticated under this Trust Agreement.

         Upon a written order of the Trust signed by one Administrative Trustee,
the Property Trustee shall authenticate the Certificates representing Capital
Securities for original issue. The


                                       33
<PAGE>   41
aggregate amount of Capital Securities outstanding at any time shall not exceed
the liquidation amount set forth in Section 7.1(a)(i).

         The Property Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Certificates. An authenticating agent may authenticate
Certificates whenever the Property Trustee may do so. Each reference in this
Trust Agreement to authentication by the Property Trustee includes
authentication by such agent. An authenticating agent has the same rights as the
Property Trustee to deal with the Sponsor or an Affiliate of the Sponsor.

                  (d)      The consideration received by the Trust for the
issuance of the Securities shall constitute a contribution to the capital of the
Trust and shall not constitute a loan to the Trust.

                  (e)      Upon issuance of the Securities as provided in this
Trust Agreement, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable undivided beneficial interests in the assets of
the Trust.

                  (f)      Every Person, by virtue of having become a Holder or
a Capital Security Beneficial Owner in accordance with the terms of this Trust
Agreement, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Trust Agreement and the terms of the Securities.

                  (g)      The holders of the Securities shall have no
preemptive or similar rights.

         SECTION 7.2. Distributions.

                  (a)      As owners of undivided beneficial ownership interests
in the Debentures, holders of Securities shall be entitled to receive cumulative
cash Distributions at the rate per annum of _______% of the stated liquidation
amount of $____ per Security. Pursuant to the Indenture, the amount of interest
on the Debentures payable for any period shorter than a full quarterly interest
period, and, as a result, Distributions on the Securities payable for any period
shorter than a full quarterly distribution period shall be computed on the basis
of a 30-day month and for periods of less than a month, the actual number of
days elapsed per 30-day month. Subject to Section 7.1(b), Distributions shall be
made on the Capital Securities and the Common Securities on a Pro Rata basis.
Pursuant to the Indenture, interest on the Debentures shall, from the date of
original issue, accrue and be cumulative, and, as a result Distributions on the
Securities shall, from the date of original issue, accumulate and be cumulative.
Distributions shall be payable quarterly in arrears on each _____________ __,
__________ __, ___________ __ and ______________ __ of each year, commencing
___________ __, 20__, when, as and if available for payment, by the Property
Trustee, except as otherwise described below. Distributions are payable only to
the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent that the Trust has funds available for the
payment of such Distributions in the Property Account.

                  (b)      Pursuant to the Indenture, interest not paid on the
scheduled payment date will accrue and compound quarterly at the rate of
_______% per annum, and, as a result, interests on the Debentures not paid on
the scheduled payment date will accrue and compound quarterly at the rate of
_______% per annum (and, as a result) the Distributions on the Securities


                                       34
<PAGE>   42
will accumulate and compound at the rate of _______% per annum ("Compounded
Distributions"). "Distributions" shall mean ordinary cumulative distributions
together with any Compounded Distributions.

                  (c)      If and to the extent that the Debenture Issuer makes
a payment of interest, premium and/or principal on the Debentures held by the
Property Trustee (the amount of any such payment being a "Payment Amount"), the
Property Trustee shall and is directed, to the extent funds are available for
that purpose, make a Pro Rata distribution of the Payment Amount to Holders,
subject to Section 7.1(b).

                  (d)      Distributions on the Securities shall be payable to
the Holders thereof as they appear on the register of the Trust as of the close
of business on the relevant record dates. While the Capital Securities are
represented by one or more Global Securities, the relevant record dates shall be
the close of business the Business Day preceding such Distribution payment date;
otherwise the relevant record date shall be the fifteenth day (whether or not a
Business Day) preceding such Distribution payment date. At all times, the
Distribution payment dates shall correspond to the interest payment dates on the
Debentures. Distributions payable on any Securities that are not punctually paid
on any Distribution payment date, as a result of the Debenture Issuer having
failed to make a payment under the Debentures, shall cease to be payable to the
Person in whose name such Securities are registered on the relevant record date,
and such defaulted Distribution will instead be payable to the Person in whose
name such Securities are registered on the special record date or other
specified date determined in accordance with this Trust Agreement. If any date
on which Distributions are payable on the Securities is not a Business Day, then
payment of the Distribution 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), with the same force and effect as if made on such
payment date.

                  (e)      In the event that there is any money or other
property held by or for the Trust that is not accounted for hereunder, such
property shall be distributed Pro Rata among the Holders of the Securities
except as provided in Section 7.1(b).

         SECTION 7.3. Redemption of Securities.

                  (a)      Upon the repayment or redemption, in whole or in
part, of the Debentures held by the Trust, whether at the stated maturity of the
Debentures or upon earlier redemption as provided in the Indenture, the proceeds
from such repayment or redemption shall be simultaneously applied Pro Rata
(subject to Section 7.1(b)) to redeem Securities having an aggregate liquidation
amount equal to the aggregate principal amount of the Debentures so repaid or
redeemed at the Redemption Price. Holders shall be given not less than 30 nor
more than 60 days notice of such redemption in accordance with Section 7.4.

                  (b)      On the date fixed for any distribution of Debentures,
upon dissolution of the Trust, (i) the Securities will no longer be deemed to be
outstanding and (ii) certificates representing Securities will be deemed to
represent the Debentures having an aggregate principal amount equal to the
stated liquidation amount of, and bearing accrued and unpaid interest equal


                                       35
<PAGE>   43
to accumulated and unpaid distributions on, such Securities until such
certificates are presented to the Sponsor or its agent for transfer or
reissuance.

         SECTION 7.4. Redemption Procedures.

                  (a)      Notice of any redemption of, or notice of
distribution of Debentures in exchange for, the Securities (a
"Redemption/Distribution Notice"), which notice shall be irrevocable, will be
given by the Trust by mail to each Holder of Securities to be redeemed or
exchanged not fewer than 30 nor more than 60 days before the date fixed for
redemption or exchange thereof which, in the case of a redemption, will be the
date fixed for redemption of the Debentures. For purposes of the calculation of
the date of redemption or exchange and the dates on which notices are given
pursuant to this Section 7.4(a), a Redemption/Distribution Notice shall be
deemed to be given on the day such notice is first mailed by first-class mail,
postage prepaid, to Holders of Securities. Each Redemption/Distribution Notice
shall be addressed to the Holders of Securities at the address of each such
Holder appearing in the register of the Trust. No defect in the
Redemption/Distribution Notice or in the mailing of either thereof with respect
to any Holder shall affect the validity of the redemption or exchange
proceedings with respect to any other Holder.

                  (b)      If fewer than all the outstanding Securities are to
be so redeemed, the Common Securities and the Capital Securities will be
redeemed Pro Rata (subject to Section 7.1(b)) and the Capital Securities to be
redeemed will be redeemed as described in Section 7.4(c) below. The particular
Capital Securities to be redeemed will be selected on a Pro Rata basis by the
Property Trustee from the outstanding Capital Securities not previously called
for redemption, by such method (including, without limitation, by lot) as the
Property Trustee shall deem fair and appropriate. The Trust may not redeem the
Securities in part unless all accumulated and unpaid Distributions to the date
of redemption have been paid in full on all Securities then outstanding. For all
purposes of this Trust Agreement, unless the context otherwise requires, all
provisions relating to the redemption of Capital Securities shall relate, in the
case of any Capital Security redeemed or to be redeemed only in part, to the
portion of the aggregate liquidation amount of Capital Securities which has been
or is to be redeemed.

                  (c)      Subject to the Trust's fulfillment of the notice
requirements set forth in Section 7.4(a) above, if Securities are to be
redeemed, then (i) with respect to Capital Securities represented by one or more
Global Securities, by 12:00 noon, New York City time, on the redemption date,
provided that the Debenture Issuer has paid the Property Trustee a sufficient
amount of cash in connection with the related redemption or maturity of the
Debentures, the Property Trustee will deposit irrevocably with the Depositary or
its nominee (or successor Clearing Agency or its nominee) funds sufficient to
pay the applicable Redemption Price with respect to the Capital Securities and
will give the Depositary irrevocable instructions and authority to pay the
Redemption Price to the Holders of the Capital Securities and (ii) with respect
to Securities not represented by one or more Global Securities, provided that
the Debenture Issuer has paid the Property Trustee a sufficient amount of cash
in connection with the related redemption or maturity of the Debentures, the
Property Trustee will give the Paying Agent irrevocable instructions and
authority to pay the relevant Redemption Price to the Holders of such Securities
upon surrender of their certificates evidencing the Capital Securities. Payment
of the Redemption Price on the Capital Securities will be made to the
recordholders thereof as


                                       36
<PAGE>   44
they appear on the register of the Trust on the relevant record date, which
shall be one Business Day prior to the relevant redemption date; provided,
however, that with respect to the Capital Securities not represented by one or
more Global Securities, the relevant record date shall be the date fifteen days
prior to the relevant redemption date. If any date fixed for redemption of
Securities 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) with the
same force and effect as if made on such date fixed for redemption. If, however,
the Business Day falls in the next calendar year, then payment of the Redemption
Price will be made on the immediately preceding Business Day with the same force
and effect as if made on such date fixed for redemption. If payment of the
Redemption Price in respect of any Securities is not paid because the payment of
the Redemption Price on the Debentures is not made, interest will continue to
accrue on the Debentures, and, as a result, Distributions on such Securities
will continue to accumulate at the then applicable rate from the original
redemption date to the actual date of payment, in which case the actual payment
date will be considered the date fixed for redemption for purposes of
calculating the Redemption Price. For these purposes, the applicable Redemption
Price shall not include Distributions which are being paid to Holders who were
Holders on a relevant record date. If a Redemption/Distribution Notice shall
have been given and funds deposited or paid as required, then immediately prior
to the close of business on the date of such deposit or payment, Distributions
will cease to accumulate on the Securities called for redemption and all rights
of Holders of such Securities so called for redemption will cease, except the
right of the Holders to receive the Redemption Price, but without interest on
such Redemption Price, and from and after the date fixed for redemption, such
Securities will cease to be outstanding.

         Neither the Administrative Trustees nor the Trust shall be required to
register or cause to be registered the transfer of any Securities that have been
called for redemption, except in the case of any Securities being redeemed in
part, any portion thereof not to be redeemed.

                  (d)      Subject to the foregoing and applicable law
(including, without limitation, United States federal securities laws), the
Debenture Issuer or its subsidiaries may at any time and from time to time
purchase outstanding Capital Securities by tender, in the open market or by
private agreement.

         SECTION 7.5. Voting Rights of Capital Securities.

                  (a)      Except as provided under Section 6.6, Section 11.1
and this Article 7 and as otherwise required by the Business Trust Act, the
Trust Indenture Act and other applicable law, the Holders of the Capital
Securities shall have no voting rights.

                  (b)      Subject to the requirement of the Property Trustee
obtaining a tax opinion in certain circumstances set forth in Section 7.5(d)
below, the Holders of a Majority in Liquidation Amount of the Capital Securities
voting separately as a class have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Property Trustee,
or to direct the exercise of any trust or power conferred upon the Property
Trustee under the Trust Agreement, including the right to direct the Property
Trustee, as Holder of the Debentures, to (i) exercise the remedies available to
it under the Indenture as a Holder of the Debentures; (ii) consent to any
amendment or modification of the Indenture or the


                                       37
<PAGE>   45
Debentures where such consent shall be required or (iii) waive any past default
and its consequences that is waivable under Section 5.13 of the Indenture;
provided, however, that if an Indenture Event of Default has occurred and is
continuing, then the Holders of 25% of the aggregate liquidation amount of the
Capital Securities may direct the Property Trustee to declare the principal of
and interest on the Debentures due and payable; provided, further, that where a
consent or action under the Indenture would require the consent or act of the
Holders of more than a majority of the aggregate principal amount of Debentures
affected thereby, only the Holders of the percentage of the aggregate stated
liquidation amount of the Capital Securities which is at least equal to the
percentage required under the Indenture may direct the Property Trustee to give
such consent to take such action.

                  (c)      If the Property Trustee fails to enforce its rights
under the Debentures after a Holder of Capital Securities has made a written
request, such Holder of Capital Securities may, to the extent permitted by
applicable law, institute a legal proceeding directly against the Debenture
Issuer to enforce the Property Trustee's rights under the Indenture without
first instituting any legal proceeding against the Property Trustee or any other
Person. In addition, if a Trust Enforcement Event has occurred and is continuing
and such event is attributable to the failure of the Debenture Issuer to make
any interest, principal or other required payments when due under the Indenture,
then a Holder of Capital Securities may directly institute a Direct Action
against the Debenture Issuer on or after the respective due date specified in
the Debentures.

                  (d)      The Property Trustee shall notify all Holders of the
Capital Securities of any notice of any Indenture Event of Default received from
the Debenture Issuer with respect to the Debentures. Such notice shall state
that such Indenture Event of Default also constitutes a Trust Enforcement Event.
Except with respect to directing the time, method, and place of conducting a
proceeding for a remedy, the Property Trustee shall be under no obligation to
take any of the actions described in clause 7.5(b)(i) and (ii) above unless the
Property Trustee has obtained an opinion of independent tax counsel to the
effect that the Trust will not be classified as an association or publicly
traded partnership taxable as a corporation for United States federal income tax
purposes as a result of such action.

                  (e)      In the event the consent of the Property Trustee, as
the Holder of the Debentures, is required under the Indenture with respect to
any amendment or modification of the Indenture, the Property Trustee shall
request the direction of the Holders of the Capital Securities with respect to
such amendment or modification and shall vote with respect to such amendment or
modification as directed by not less than a majority in liquidation amount of
the Capital Securities voting together as a single class; provided, however,
that where a consent under the Indenture would require the consent of the
Holders of more than a majority of the aggregate principal amount of the
Debentures, the Property Trustee may only give such consent at the direction of
the Holders of at least the same proportion in aggregate stated liquidation
amount of the Securities. The Property Trustee shall not take any such action in
accordance with the directions of the Holders of the Securities unless the
Property Trustee has obtained an opinion of independent tax counsel to the
effect that the Trust will not be classified as an association or publicly
traded partnership taxable as a corporation for United States federal income tax
purposes as a result of such action.

                  (f)      A waiver of an Indenture Event of Default with
respect to the Debentures will constitute a waiver of the corresponding Trust
Enforcement Event.

                  (g)      Any required approval or direction of Holders of
Capital Securities may be given at a separate meeting of Holders of Capital
Securities convened for such purpose, at a meeting of all of the Holders of
Securities or pursuant to written consent. The Administrative Trustees will
cause a notice of any meeting at which Holders of Capital Securities are
entitled to vote to be mailed to each Holder of record of Capital Securities.
Each such notice will include a statement setting forth (i) the date of such
meeting, (ii) a description of any resolution proposed for adoption at such
meeting on which such Holders are entitled to vote and (iii) instructions for
the delivery of proxies.

                  (h)      No vote or consent of the Holders of Capital

Securities or distribute Debentures in accordance with this Trust Agreement and
the terms of the Securities.

                  (i)      Notwithstanding that Holders of Capital Securities
are entitled to vote or consent under any of the circumstances described above,
any of the Securities that are owned at such time by the Debenture Issuer, any
Administrative Trustee or any entity directly or indirectly controlled by, or
under direct or indirect common control with, the Debenture Issuer or any
Administrative Trustee, shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if such Securities were not
outstanding; provided, however, that Persons otherwise eligible to vote to whom
the Debenture Issuer or any of its subsidiaries have pledged Capital Securities
may vote or consent with respect to such pledged Capital Securities under any of
the circumstances described herein.

                  (j)      Subject to Sections 6.6(a) and 7.5(k), Holders of the
Capital Securities shall have no rights to appoint or remove the Trustees, who
may be appointed, removed or replaced solely by the Common Securities Holder.

                  (k)      If an Indenture Event of Default has occurred and is
continuing, the Property Trustee and the Delaware Trustee may be removed at such
time only by a Majority in Liquidation Amount of the Capital Securities.

                  (l)      The Trustees shall not revoke any action previously
authorized or approved by a vote of the Holders of the Securities, except by a
subsequent vote of the Holders of the Securities.

         SECTION 7.6. Voting Rights of Common Securities.

                  (a)      Except as provided under Section 6.1(b), this Section
7.6 or Section 11.1 or as otherwise required by the Business Trust Act, the
Trust Indenture Act or other applicable law or provided by the Trust Agreement,
the Holders of the Common Securities will have no voting rights.

                  (b)      Subject to Sections 6.6(a) and 7.5(k), the Holders of
the Common Securities shall be entitled, in accordance with Article VI of this
Trust Agreement, to vote to appoint, remove or replace any Trustee or to
increase or decrease the number of Trustees.

<PAGE>   47
                  (c)      Subject to Section 2.6 and only after all Trust
Enforcement Events with respect to the Capital Securities have been cured,
waived, or otherwise eliminated and subject to the requirement of the Property
Trustee obtaining a tax opinion in certain circumstances set forth in this
paragraph (c), the Holders of a Majority in Liquidation Amount of the Common
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or direct the
exercise of any trust or power conferred upon the Property Trustee under this
Trust Agreement, including the right to direct the Property Trustee, as Holder
of the Debentures, to (i) exercise the remedies available to it under the
Indenture as a Holder of the Debentures, (ii) consent to any amendment or
modification of the Indenture or the Debentures where such consent shall be
required or (iii) waive any past default and its consequences that is waivable
under Section 5.13 of the Indenture; provided, however, that where a consent or
action under the Indenture would require the consent or act of the Holders of
more than a majority of the aggregate principal amount of Debentures affected
thereby, only the Holders of the percentage of the aggregate stated liquidation
amount of the Common Securities which is at least equal to the percentage
required under the Indenture may direct the Property Trustee to have such
consent or take such action. Except with respect to directing the time, method,
and place of conducting a proceeding for a remedy, the Property Trustee shall be
under no obligation to take any of the actions described in clause 7.6(c)(i) and
(ii) above unless the Property Trustee has obtained an opinion of independent
tax counsel to the effect that, as a result of such action, for United States
federal income tax purposes the Trust will not be classified as other than a
grantor trust.

                  (d)      If the Property Trustee fails to enforce its rights
under the Debentures after a Holder of Common Securities has made a written
request, such Holder of Common Securities may, to the extent permitted by
applicable law, directly institute a legal proceeding directly against the
Debenture Issuer to enforce the Property Trustee's rights under the Debentures
without first instituting any legal proceeding against the Property Trustee or
any other Person.

                  (e)      A waiver of an Indenture Event of Default with
respect to the Debentures will constitute a waiver of the corresponding Trust
Enforcement Event.

                  (f)      Any required approval or direction of Holders of
Common Securities may be given at a separate meeting of Holders of Common
Securities convened for such purpose, at a meeting of all of the Holders of
Securities or pursuant to written consent. The Administrative Trustees will
cause a notice of any meeting at which Holders of Common Securities are entitled
to vote to be mailed to each Holder of record of Common Securities. Each such

         SECTION 7.7. Paying Agent.

         In the event that any Capital Securities are not in book-entry only
form, the Trust shall maintain in the Borough of Manhattan, City of New York,
State of New York, an office or agency where the Capital Securities may be
presented for payment ("Paying Agent"). The Trust may appoint the paying agent
and may appoint one or more additional paying agents in such other locations as
it shall determine. The term "Paying Agent" includes any additional paying
agent. The Trust may change any Paying Agent without prior notice to the
Holders. The Trust shall notify the Property Trustee of the name and address of
any Paying Agent not a party to this Trust Agreement. If the Trust fails to
appoint or maintain another entity as Paying Agent, the Property Trustee shall
act as such. The Trust or any of its Affiliates may act as Paying Agent. The
Property Trustee shall initially act as Paying Agent for the Securities. In the
event the Property Trustee shall no longer be the Paying Agent, the
Administrative Trustees shall appoint a successor (which shall be a bank or
trust company acceptable to the Debenture Issuer) to act as Paying Agent. The
Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Property Trustee and the Debenture Issuer.

         SECTION 7.8. Listing.

         The Sponsor shall use its best efforts to cause the Capital Securities
to be listed for quotation on the New York Stock Exchange.

         SECTION 7.9. Transfer of Securities.

                  (a)      Securities may only be transferred, in whole or in
part, in accordance with the terms and conditions set forth in this Trust
Agreement and in the terms of the Securities. To the fullest extent permitted by
law, any transfer or purported transfer of any Security not made in accordance
with this Trust Agreement shall be null and void.

                  (b)      (i)      Subject to this Article 7, Capital
                  Securities shall be freely transferable.

                           (ii)     The Holder of the Common Securities may not
                  transfer the Common Securities except (A) in compliance with a
                  consolidation, merger, sale, conveyance or lease of the
                  Sponsor in compliance with Article VIII of the Indenture or
                  (B) to the Sponsor or an Affiliate thereof in compliance with
                  applicable law, including the Securities Act and applicable
                  state securities and blue sky laws. To the fullest extent
                  permitted by law, any attempted transfer of the Common
                  Securities other than as set forth in the immediately
                  preceding sentence shall be null and void.

                  (c)      The Trust shall cause to be kept at the Corporate
Trust Office of the Property Trustee a register (the register maintained in such
office being herein sometimes referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Trust shall
provide for the registration of Capital Securities and of transfers of Capital
Securities. The Property Trustee is hereby appointed "Security Registrar" for
the purpose of registering Capital Securities and transfers of Capital
Securities as herein provided.

<PAGE>   49
                  (d)      Upon surrender for registration of transfer of any
Security at an office or agency of the Trust designated for such purpose, the
Trust shall execute, and the Property Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities
of any authorized denominations and of a like aggregate principal amount.

                  (e)      At the option of the Holder, Securities may be
exchanged for other Securities of any authorized denominations and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
such office or agency. Whenever any Securities are so surrendered for exchange,
the Trust shall execute, and in the case of Capital Securities the Property
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

                  (f)      Every Security presented or surrendered for
registration of transfer or for exchange shall (if so required by the Trust or
the Property Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Trust and the Security
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing.

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

                  (h)      If the Securities are to be redeemed in part, the
Trust shall not be required (A) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of any such Securities
selected for redemption under Section 7.4 and ending at the close of business on
the day of such mailing, or (B) to register the transfer or exchange of any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

         SECTION 7.10. Mutilated, Destroyed, Lost or Stolen Certificates.

If:

                  (a)      any mutilated Certificates should be surrendered to
the Administrative Trustees, or if the Administrative Trustees shall receive
evidence to their satisfaction of the destruction, loss or theft of any
Certificate; and

                  (b)      there shall be delivered to the Administrative
Trustees such security or indemnity as may be required by them to keep each of
the Trustees, the Sponsor and the Trust harmless,

then, in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any Administrative Trustee on behalf of the Trust shall
execute and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Certificate, a new Certificate of like denomination.
In connection with the issuance of any new Certificate under this Section 7.10,
the Administrative Trustees may require the payment of a sum sufficient to


                                       42
<PAGE>   50
cover any tax or other governmental charge that may be imposed in connection
therewith. Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

         SECTION 7.11. Deemed Security Holders.

         The Trustees may treat the Person in whose name any Certificate shall
be registered on the register of the Trust as the sole holder of such
Certificate and of the Securities represented by such Certificate for purposes
of receiving Distributions and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other claim to or
interest in such Certificate or in the Securities represented by such
Certificate on the part of any Person, whether or not the Trust shall have
actual or other notice thereof.

         SECTION 7.12. Global Securities.

         On initial issuance, the Capital Securities shall be issued in
definitive form to the Sponsor. Upon transfer by the Sponsor of the Capital
Securities, the Capital Securities may be issued in the form of one or more
Global Securities. If the Capital Securities are to be issued in the form of one
or more Global Securities, then an Administrative Trustee on behalf of the Trust
shall execute and the Property Trustee shall authenticate and deliver one or
more Global Securities that (i) shall represent and shall be denominated in an
amount equal to the aggregate liquidation amount of all of the Capital
Securities to be issued in the form of Global Securities and not yet cancelled,
(ii) shall be registered in the name of the Depositary for such Global Security
or the nominee of such Depositary, and (iii) shall be delivered by the Property
Trustee to such Depositary or pursuant to such Depositary's instructions. Global
Securities shall bear a legend substantially to the following effect:

         "This Capital Security is a Global Security within the meaning of the
         Trust Agreement hereinafter referred to and is registered in the name
         of The Depository Trust Company, a New York corporation (the
         "Depositary"), or a nominee of the Depositary. This Capital Security is
         exchangeable for Capital Securities registered in the name of a person
         other than the Depositary or its nominee only in the limited
         circumstances described in the Trust Agreement and no transfer of this
         Capital Security (other than a transfer of this Capital Security as a
         whole by the Depositary to a nominee of the Depositary or by a nominee
         of the Depositary to the Depositary or another nominee of the
         Depositary) may be registered except in limited circumstances.

         Unless this Capital Security Certificate is presented by an authorized
         representative of the Depositary to USB Capital ______ or its agent for
         registration of transfer, exchange or payment, and any Capital Security
         Certificate issued is registered in the name of Cede & Co. or such
         other name as requested by an authorized representative of the
         Depositary (and any payment hereon is made to Cede & Co. or to such
         other entity as is requested by an authorized representative of the
         Depositary), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
         OTHERWISE BY OR TO ANY PERSON IS


                                       43
<PAGE>   51
         WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an
         interest herein."

         Capital Securities not represented by a Global Security issued in
exchange for all or a part of a Global Security pursuant to this Section 7.12
shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Property Trustee. Upon execution and
authentication, the Property Trustee shall deliver such Capital Securities not
represented by a Global Security to the Persons in whose names such definitive
Capital Securities are so registered.

         At such time as all interests in Global Securities have been redeemed,
repurchased or cancelled, such Global Securities shall be, upon receipt thereof,
cancelled by the Property Trustee in accordance with standing procedures of the
Depositary. At any time prior to such cancellation, if any interest in Global
Securities is exchanged for Capital Securities not represented by a Global
Security, redeemed, cancelled or transferred to a transferee who receives
Capital Securities not represented by a Global Security therefor or any Capital
Security not represented by a Global Security is exchanged or transferred for
part of Global Securities, the principal amount of such Global Securities shall,
in accordance with the standing procedures of the Depositary, be reduced or
increased, as the case may be, and an endorsement shall be made on such Global
Securities by the Property Trustee to reflect such reduction or increase.

         The Trust and the Property Trustee may for all purposes, including the
making of payments due on the Capital Securities, deal with the Depositary as
the authorized representative of the Holders for the purposes of exercising the
rights of Holders hereunder. The rights of the owner of any beneficial interest
in a Global Security shall be limited to those established by law and agreements
between such owners and depository participants provided, that no such agreement
shall give any rights to any Person against the Trust or the Property Trustee
without the written consent of the parties so affected. Multiple requests and
directions from and votes of the Depositary as holder of Capital Securities in
global form with respect to any particular matter shall not be deemed
inconsistent to the extent they do not represent an amount of Capital Securities
in excess of those held in the name of the Depositary or its nominee.

         If at any time the Depositary for any Capital Securities represented by
one or more Global Securities notifies the Trust that it is unwilling or unable
to continue as Depositary for such Capital Securities or if at any time the
Depositary for such Capital Securities shall no longer be eligible under this
Section 7.12, the Trust shall appoint a successor Depositary with respect to
such Capital Securities. If a successor Depositary for such Capital Securities
is not appointed by the Trust within 90 days after the Trust receives such
notice or becomes aware of such ineligibility, the Trust's election that such
Capital Securities be represented by one or more Global Securities shall no
longer be effective and the Trust shall execute, and the Property Trustee will
authenticate and deliver, Capital Securities in definitive registered form, in
any authorized denominations, in an aggregate liquidation amount equal to the
principal amount of the Global Security or Capital Securities representing such
Capital Securities in exchange for such Global Security or Capital Securities.


                                       44
<PAGE>   52
         The Trust may at any time and in its sole discretion determine that the
Capital Securities issued in the form of one or more Global Securities shall no
longer be represented by a Global Security or Capital Securities. In such event
the Trust shall execute, and the Property Trustee, shall authenticate and
deliver, Capital Securities in definitive registered form, in any authorized
denominations, in an aggregate liquidation amount equal to the principal amount
of the Global Security or Capital Securities representing such Capital
Securities, in exchange for such Global Security or Capital Securities.

         Notwithstanding any other provisions of this Trust Agreement (other
than the provisions set forth in Section 7.9), Global Securities may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

         Interests of beneficial owners in a Global Security may be transferred
or exchanged for Capital Securities not represented by a Global Security and
Capital Securities not represented by a Global Security may be transferred or
exchange for Global Securities in accordance with rules of the Depositary and
the provisions of Section 7.9.

                      DISSOLUTION AND TERMINATION OF TRUST

         SECTION 8.1. Dissolution and Termination of Trust.

                  (a)      The Trust shall dissolve upon the earliest of:

                           (i)      the bankruptcy of the Holder of the Common

                  days after the revocation without a reinstatement thereof;

                           (iii)    the entry of a decree of judicial
                  dissolution of the Sponsor or the Trust;

                           (iv)     the time when all of the Securities shall
                  have been called for redemption and the amounts then due shall
                  have been paid to the Holders in accordance with the terms of
                  the Securities;

                           (v)      at the Sponsor's election by notice and
                  direction to the Property Trustee to distribute the Debentures

                  Securities, subject to the receipt of any necessary approvals
                  by the Federal Reserve that may then be required under the
                  applicable capital guidelines or policies of the Federal
                  Reserve; provided that the Sponsor will be required to obtain
                  an opinion of an independent counsel that the distribution of
                  the


                                       45
<PAGE>   53
                  Debentures will not be taxable to the Holders of the Capital
                  Securities for United States federal income tax purposes; or

                           (vi)     the time when all of the Administrative
                  Trustees and the Sponsor shall have consented to dissolution
                  of the Trust provided such action is taken before the issuance
                  of any Securities.

                  (b)      As soon as is practicable after the occurrence of an
event referred to in Section 8.1(a) and upon completion of the winding up and
liquidation of the Trust, the Trustees shall terminate the Trust by filing a
certificate of cancellation with the Secretary of State of the State of
Delaware.

                  (c)      The provisions of Section 4.2 and Article 9 shall
survive the termination of the Trust.

         SECTION 8.2. Liquidation Distribution Upon Dissolution of the Trust.

                  (a)      In the event of any voluntary or involuntary
liquidation, dissolution, or winding-up of the Trust (each a "Liquidation"), the
Holders of the Securities on the date of the Liquidation will be entitled to
receive, out of the assets of the Trust available for distribution to Holders of
Securities after satisfaction of the Trust's liabilities to creditors, if any,
distributions in cash or other immediately available funds in an amount equal to
the aggregate of the stated liquidation amount of $_____ per Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"), unless, in connection with such
Liquidation, Debentures in an aggregate stated principal amount equal to the
aggregate stated liquidation amount of, with an interest rate identical to the
distribution rate of, and accumulated and unpaid interest equal to accrued and
unpaid Distributions on, such Securities shall be distributed on a Pro Rata
basis to the Holders of the Securities in exchange for such Securities.

                  (b)      If, upon any such Liquidation, 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 the
amounts payable directly by the Trust on the Securities shall be paid on a Pro
Rata basis. The Holders of the Common Securities will be entitled to receive
distributions upon any such Liquidation Pro Rata with the Holders of the Capital
Securities except that if an Indenture Event of Default has occurred and is
continuing, the Capital Securities shall have a preference over the Common
Securities with regard to such distributions as provided for in Section 7.1(b).

                               TRUSTEES OR OTHERS

         SECTION 9.1. Liability.

                  (a)      Except as expressly set forth in this Trust
Agreement, the Guarantee and the terms of the Securities, the Sponsor:

                           (i)      shall not be personally liable for the
                  return of any portion of the capital contributions (or any
                  return thereon) of the Holders of the Securities which shall
                  be made solely from assets of the Trust; and

                           (ii)     shall not be required to pay to the Trust or
                  to any Holder of Securities any deficit upon dissolution of
                  the Trust or otherwise.

                  (b)      Pursuant to Section 3803(a) of the Business Trust
Act, the Holder of the Common Securities 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; provided, however, the Holders of the Common Securities shall be
liable for all of the debts and obligations of the Trust (other than with
respect to the Securities) to the extent not satisfied out of the Trust's
assets.

                  (c)      Pursuant to Section 3803(a) of the Business Trust
Act, the Holders of the Capital Securities 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.

         SECTION 9.2. Exculpation.

                  (a)      No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Trust Agreement or by
law, except that an Indemnified Person shall be liable for any such loss, damage
or claim incurred by reason of such Indemnified Person's negligence or willful
misconduct with respect to such acts or omissions.

                  (b)      An Indemnified Person 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 Indemnified Person 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


                                       47
<PAGE>   55
pertinent to the existence and amount of assets from which Distributions to
Holders of Securities might properly be paid.

         SECTION 9.3. Fiduciary Duty.

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

                  (b)      Unless otherwise expressly provided herein:

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

                           (ii)     whenever this Trust Agreement or any other
                  agreement contemplated herein or therein provides that an
                  Indemnified Person shall act in a manner that is, or provides
                  terms that are, fair and reasonable to the Trust or any Holder
                  of Securities,

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

                  (c)      Whenever in this Trust Agreement an Indemnified
Person is permitted or required to make a decision:

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

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

         SECTION 9.4. Indemnification.

                  (a)      The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Debenture Issuer Indemnified Person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Trust) by reason
of the fact that he is or was a Debenture Issuer Indemnified Person against
expenses (including attorney fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the Trust,
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe his conduct was unlawful. The termination of any action, suit or
proceeding by judgment, order, settlement, conviction or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the Debenture Issuer Indemnified Person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Trust, and, with respect to any criminal action or proceeding,
had reasonable cause to believe that his conduct was unlawful.

                  (b)      The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Debenture Issuer Indemnified Person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Trust to procure a judgment
in its favor by reason of the fact that he is or was a Debenture Issuer
Indemnified Person against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection with the defense or settlement of such
action or suit if he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the Trust and except that no
such indemnification shall be made in respect of any claim, issue or matter as
to which such Debenture Issuer Indemnified Person shall have been adjudged to be
liable to the Trust unless and only to the extent that the Court of Chancery of
Delaware or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which such Court of Chancery or such other court
shall deem proper.

                  (c)      Any indemnification under paragraphs (a) and (b) of
this Section 9.4 (unless ordered by a court) shall be made by the Debenture
Issuer only as authorized in the specific case upon a determination that
indemnification of the Debenture Issuer Indemnified Person is proper in the
circumstances because he has met the applicable standard of conduct set forth in
paragraphs (a) and (b). Such determination shall be made (1) by the
Administrative Trustees by a majority vote of a quorum consisting of such
Administrative Trustees who were not parties to such action, suit or proceeding,
(2) if such a quorum is not obtainable, or, even if obtainable, if a quorum of
disinterested Administrative Trustees so directs, by independent legal counsel
in a written opinion, or (3) by the Common Security Holder of the Trust.

                  (d)      Expenses (including attorneys' fees) incurred by a
Debenture Issuer Indemnified Person in defending a civil, criminal,
administrative or investigative action, suit or proceeding referred to in
paragraphs (a) and (b) of this Section 9.4 shall be paid by the Debenture Issuer
in advance of the final disposition of such action, suit or proceeding upon
receipt of an


                                       49
<PAGE>   57
undertaking by or on behalf of such Debenture Issuer Indemnified Person to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Debenture Issuer as authorized in this Section 9.4.
Notwithstanding the foregoing, no advance shall be made by the Debenture Issuer
if a determination is reasonably and promptly made (1) by the Administrative
Trustees by a majority vote of a quorum of disinterested Administrative
Trustees, (2) if such a quorum is not obtainable, or, even if obtainable, if a
quorum of disinterested Administrative Trustees so directs, by independent legal
counsel in a written opinion or (3) the Common Security Holder of the Trust,
that, based upon the facts known to the Administrative Trustees, counsel or the
Common Security Holder at the time such determination is made, such Debenture
Issuer Indemnified Person acted in bad faith or in a manner that such person did
not believe to be in or not opposed to the best interests of the Trust, or, with
respect to any criminal proceeding, that such Debenture Issuer Indemnified
Person believed or had reasonable cause to believe his conduct was unlawful. In
no event shall any advance be made in instances where the Administrative
Trustees, independent legal counsel or Common Security Holder reasonably
determine that such person deliberately breached his duty to the Trust or its
Common or Capital Security Holders.

                  (e)      The indemnification and advancement of expenses
provided by, or granted pursuant to, the other paragraphs of this Section 9.4
shall not be deemed exclusive of any other rights to which those seeking
indemnification and advancement of expenses may be entitled under any agreement,
vote of stockholders or disinterested directors of the Debenture Issuer or
Capital Security Holders of the Trust or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office. All rights to indemnification under this Section 9.4 shall be deemed to
be provided by a contract between the Debenture Issuer and each Debenture Issuer
Indemnified Person who serves in such capacity at any time while this Section
9.4 is in effect. Any repeal or modification of this Section 9.4 shall not
affect any rights or obligations then existing.

                  (f)      The Debenture Issuer or the Trust may purchase and
maintain insurance on behalf of any person who is or was a Debenture Issuer
Indemnified Person against any liability asserted against him and incurred by
him in any such capacity, or arising out of his status as such, whether or not
the Debenture Issuer would have the power to indemnify him against such
liability under the provisions of this Section 9.4.

                  (g)      For purposes of this Section 9.4, references to "the
Trust" shall include, in addition to the resulting or surviving entity, any
constituent entity (including any constituent of a constituent) absorbed in a
consolidation or merger, so that any person who is or was a director, trustee,
officer or employee of such constituent entity, or is or was serving at the
request of such constituent entity as a director, trustee, officer, employee or
agent of another entity, shall stand in the same position under the provisions
of this Section 9.4 with respect to the resulting or surviving entity as he
would have with respect to such constituent entity if its separate existence had
continued.

                  (h)      The indemnification and advancement of expenses
provided by, or granted pursuant to, this Section 9.4 shall, unless otherwise
provided when authorized or ratified, continue as to a person who has ceased to
be a Debenture Issuer Indemnified Person and shall inure to the benefit of the
heirs, executors and administrators of such a person. The obligation to


                                       50
<PAGE>   58
indemnify as set forth in this Section 9.4 shall survive the resignation or
removal of the Delaware Trustee or the Property Trustee or the termination of
this Trust Agreement.

         SECTION 9.5. Outside Businesses.

         Subject to the provisions of Section 6.3, any Covered Person, the
Sponsor, the Delaware Trustee and the Property Trustee may engage in or possess
an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the activities of the
Trust, and the Trust and the Holders of Securities shall have no rights by
virtue of this Trust Agreement in and to such independent ventures or the income
or profits derived therefrom, and the pursuit of any such venture, even if
competitive with the activities of the Trust, shall not be deemed wrongful or
improper. No Covered Person, the Sponsor, the Delaware Trustee or the Property
Trustee shall be obligated to present any particular investment or other
opportunity to the Trust even if such opportunity is of a character that, if
presented to the Trust, could be taken by the Trust, and any Covered Person, the
Sponsor, the Delaware Trustee and the Property Trustee shall have the right to
take for its own account (individually or as a partner or fiduciary) or to
recommend to others any such particular investment or other opportunity. Any
Covered Person, the Delaware Trustee and the Property Trustee may engage or be
interested in any financial or other transaction with the Sponsor or any
Affiliate of the Sponsor, or may act as depositary for, trustee or agent for, or
act on any committee or body of holders of, securities or other obligations of
the Sponsor or its Affiliates.

         SECTION 10.1. Fiscal Year.

         The fiscal year ("Fiscal Year") of the Trust shall be the calendar
year, or such other year as is required by the Code.

         SECTION 10.2. Certain Accounting Matters.

                  (a)      At all times during the existence of the Trust, the
Administrative Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail, each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Administrative Trustees.

                  (b)      The Administrative Trustees shall cause to be
prepared and delivered to each of the Holders of Securities, within 90 days
after the end of each Fiscal Year of the Trust, annual financial statements of
the Trust, including a balance sheet of the Trust as of the end of such Fiscal
Year, and the related statements of income or loss.


                                       51
<PAGE>   59
                  (c)      The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders of Securities, an annual United
States federal income tax information statement, required by the Code,
containing such information with regard to the Securities held by each Holder as
is required by the Code and the Treasury Regulations. Notwithstanding any right
under the Code to deliver any such statement at a later date, the Administrative
Trustees shall endeavor to deliver all such statements within 30 days after the
end of each Fiscal Year of the Trust.

                  (d)      The Administrative Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
United States federal income tax law, and any other annual income tax returns
required to be filed by the Administrative Trustees on behalf of the Trust with
any state or local taxing authority.

         SECTION 10.3. Banking.

         The Trust shall maintain one or more bank accounts in the name and for
the sole benefit of the Trust; provided, however, that all payments of funds in
respect of the Debentures held by the Property Trustee shall be made directly to
the Property Account and no other funds of the Trust shall be deposited in the
Property Account. The sole signatories for such accounts shall be designated by
the Administrative Trustees; provided, however, that the Property Trustee shall
designate the signatories for the Property Account.

         SECTION 10.4. Withholding.

         The Trust and the Administrative Trustees shall comply with all
withholding requirements under United States federal, state and local law. The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably be
requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations. The Administrative Trustees shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions. To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Holder, the amount withheld shall
be deemed to be a distribution in the amount of the withholding to the Holder.
In the event of any claimed over withholding, Holders shall be limited to an
action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

                             AMENDMENTS AND MEETINGS

         SECTION 11.1. Amendments.

                  (a)      Except as otherwise provided in this Trust Agreement
or by any applicable terms of the Securities, this Trust Agreement may only be
amended by a written instrument approved and executed by the Sponsor and (i) the
Administrative Trustees (or, if there are more than two Administrative Trustees,
a majority of the Administrative Trustees) and (ii) the Property Trustee if the
amendment affects the rights, powers, duties, obligations or immunities of the
Property Trustee; and (iii) the Delaware Trustee if the amendment affects the
rights, powers, duties, obligations or immunities of the Delaware Trustee.

amendment shall be void and ineffective:

                           (i)      unless, in the case of any proposed
                  amendment, the Property Trustee shall have first received an

                  that such amendment is permitted by, and conforms to, the

                  Securities);

                           (ii)     unless, in the case of any proposed
                  amendment which affects the rights, powers, duties,
                  obligations or immunities of the Property Trustee, the
                  Property Trustee shall have first received:

                                             amendment have been satisfied; and

                                    b.       an opinion of counsel (who may be
                                             counsel to the Sponsor or the
                                             Trust) that such amendment is

                                             terms of this Trust Agreement
                                             (including the terms of the

                                             been satisfied; and

                           (iii)    to the extent the result of such amendment
                  would be to:

         SECTION 11.2. Meetings of the Holders of Securities; Action by Written
Consent.

                  (a)      Meetings of the Holders of any class of Securities
may be called at any time by the Administrative Trustees (or as provided in the
terms of the Securities) to consider and act on any matter on which Holders of
such class of Securities are entitled to act under the terms of this Trust
Agreement, the terms of the Securities or the rules of any stock exchange on
which the Capital Securities are listed or admitted for trading. The
Administrative Trustees shall call a meeting of the Holders of such class if
directed to do so by the Holders of at least 10% in Liquidation Amount of such
class of Securities. Such direction shall be given by delivering to the
Administrative Trustees one or more calls in a writing stating that the signing
Holders of Securities wish to call a meeting and indicating the general or
specific purpose for which the meeting is to be called. Any Holders of
Securities calling a meeting shall specify in writing the Certificates held by
the Holders of Securities exercising the right to call a meeting and only those
Securities specified shall be counted for purposes of determining whether the
required percentage set forth in the second sentence of this paragraph has been
met.

                  (b)      Except to the extent otherwise provided in the terms
of the Securities, the following provisions shall apply to meetings of Holders
of Securities:

                           (i)      notice of any such meeting shall be given to
                  all the Holders of Securities having a right to vote thereat
                  at least 7 days and not more than 60 days before the date of
                  such meeting. Whenever a vote, consent or approval of the
                  Holders of Securities is permitted or required under this
                  Trust Agreement or the rules of any stock exchange on which
                  the Capital Securities are listed or admitted for trading,
                  such vote, consent or approval may be given at a meeting of
                  the Holders of Securities. Any action that may be taken at a
                  meeting of the Holders of Securities may be taken without a
                  meeting and without prior notice if a consent in writing
                  setting forth the action so taken is signed by the Holders of
                  Securities owning not less than the minimum amount of
                  Securities in liquidation amount that would be necessary to
                  authorize or take such action at a meeting at which all
                  Holders of Securities having a right to vote thereon were
                  present and voting. Prompt notice of the taking of action
                  without a meeting shall be given to the Holders of Securities
                  entitled to vote who have not consented in writing. The
                  Administrative Trustees may specify that any written ballot
                  submitted to the Security Holders for the purpose of taking
                  any action without a meeting shall be returned to the Trust
                  within the time specified by the Administrative Trustees;

                           (ii)     each Holder of a Security may authorize any
                  Person to act for it by proxy on all matters in which a Holder
                  of Securities is entitled to participate, including waiving
                  notice of any meeting, or voting or participating at a
                  meeting. No proxy shall be valid after the expiration of 11
                  months from the date thereof unless otherwise provided in the
                  proxy. Every proxy shall be revocable at the pleasure of the
                  Holder of Securities executing such proxy. Except as otherwise
                  provided herein, all matters relating to the giving, voting or
                  validity of proxies shall be governed by the General
                  Corporation Law of the State of Delaware relating to proxies,
                  and judicial interpretations thereunder, as if the Trust were
                  a Delaware corporation and the Holders of the Securities were
                  stockholders of a Delaware corporation;

                           (iii)    each meeting of the Holders of the
                  Securities shall be conducted by the Administrative Trustees
                  or by such other Person that the Administrative Trustees may
                  designate; and

                           (iv)     unless the Business Trust Act, this Trust
                  Agreement, the terms of the Securities, the Trust Indenture
                  Act or the listing rules of any stock exchange on which the
                  Capital Securities are then listed for trading, otherwise
                  provides, the Administrative Trustees, in their sole
                  discretion, shall establish all other provisions relating to
                  meetings of Holders of Securities, including notice of the
                  time, place or purpose of any meeting at which any matter is
                  to be voted on by any Holders of Securities, waiver of any
                  such notice, action by consent without a meeting, the
                  establishment of a record date, quorum requirements, voting in
                  person or by proxy or any other matter with respect to the
                  exercise of any such right to vote.
