required to be part of this Trust Agreement and shall, to the extent applicable,
be governed by such provisions.

      (b) The Property Trustee shall be the only Trustee which is a Trustee for
the purposes of the TIA.

      (c) If and to the extent that any provision of this Trust Agreement
conflicts with the duties imposed by Sections 310 to 317, inclusive, of the TIA,
such imposed duties shall control.

      (d) The application of the TIA to this Trust Agreement shall not affect
the Trust's classification as a grantor trust for United States federal income
tax purposes and shall not affect the nature of the Securities as equity
securities representing undivided beneficial ownership interests in the assets
of the Trust.

      Section 2.2.  Lists of Holders of Securities.

      (a) Each of the Sponsor and the Administrative Trustees on behalf of the
Trust shall provide the Property Trustee at any time when the Property Trustee
is not also acting as Security Registrar for the Securities at least 10 days
before each Distribution payment date and at such other times as the Property
Trustee may request in writing a list, in such form and as of such date as the
Property Trustee may reasonably

<PAGE>

      may require, of the names and addresses of the Holders of the Securities
("List of Holders"); provided that neither the Sponsor nor the Administrative
Trustees on behalf of the Trust shall be obligated to provide such List of
Holders at any time the List of Holders does not differ from the most recent
List of Holders given to the Property Trustee by the Sponsor and the
Administrative Trustees on behalf of the Trust. The Property Trustee shall
preserve, in as current a form as is reasonably practicable, all information
contained in Lists of Holders given to it or which it receives in the capacity
as Paying Agent (if acting in such capacity); provided that the Property Trustee
may destroy any List of Holders previously given to it on receipt of a new List
of Holders.

      (b) The Property Trustee shall comply with its obligations under, and
shall be entitled to the benefits of, Sections 311(a), 311(b) and 312(b) of the
TIA.

      Section 2.3.  Reports by the Property Trustee. Within 60 days after May
15 of each year (commencing with the year in which the first anniversary of the
issuance of the Preferred Securities occurs), the Property Trustee shall provide
to the Holders of the Preferred Securities such reports as are required by
Section 313(a) of the TIA, if any, in the form and in the manner provided by

      Section 2.6.  Trust Enforcement Events; Waiver.

      (a) The Holders of a Majority in Liquidation Amount of the Preferred
Securities may, by vote or written consent, on behalf of the Holders of all of
the Preferred Securities, waive any past Trust Enforcement Event in respect of
the Preferred Securities and its consequences; provided that, if the underlying
Indenture Event of Default:

            (i) is not waivable under the Indenture, the Trust Enforcement Event
      under the Trust Agreement shall also not be waivable; or
<PAGE>

            (ii) requires the consent or vote of the Holders of greater than a
      majority in principal amount of the Debentures (a "Super Majority") to be
      waived under the Indenture, the related Trust Enforcement Event under the
      Trust Agreement may only be waived by the vote or written consent of the
      Holders of at least the proportion in liquidation amount of the Preferred
      Securities that the relevant Super Majority represents of the aggregate
      principal amount of the Debentures outstanding.

      The foregoing provisions of this Section 2.6(a) shall be in lieu of
Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is
hereby expressly excluded from this Trust Agreement and the Securities, as
permitted by the TIA. Upon such waiver, any such default shall cease to exist,
and any Trust Enforcement Event with respect to the Preferred Securities arising
therefrom shall be deemed to have been cured, for every purpose of this Trust
Agreement and the Preferred Securities, but no such waiver shall extend to any
subsequent or other Trust Enforcement Event with respect to the Preferred
Securities or impair any right consequent thereon. Any waiver by the Holders of
the Preferred Securities of a Trust Enforcement Event with respect to the
Preferred Securities shall also be deemed to constitute a waiver by the Holders
of the Common Securities of any such Trust Enforcement Event with respect to the
Common Securities for all purposes of this Trust Agreement without any further
act, vote, or consent of the Holders of the Common Securities.

      (b) The Holders of a Majority in Liquidation Amount of the Common
Securities may, by vote or written consent, on behalf of the Holders of all of
the Common Securities, waive any past Trust Enforcement Event in respect of the
Common Securities and its consequences; provided that, if the underlying
Indenture Event of Default:

            (i) is not waivable under the Indenture, except where the Holders of
      the Common Securities are deemed to have waived such Trust Enforcement
      Event under the Trust Agreement as provided below in this Section 2.6(b),
      the Trust Enforcement Event under the Trust Agreement shall also not be
      waivable; or

            (ii) requires the consent or vote of a Super Majority to be waived
      under the Indenture, except where the Holders of the Common Securities are
      deemed to have waived such Trust Enforcement Event under the Trust
      Agreement as provided below in this Section 2.6(b), the Trust Enforcement
      Event under the Trust Agreement may only be waived by the vote or written
      consent of the Holders of at least the proportion in liquidation amount of
      the Common Securities that the relevant Super Majority represents of the
      aggregate principal amount of the Debentures outstanding; provided,
      further, each Holder of Common Securities will be deemed to have waived
      any Trust Enforcement Event and all Trust Enforcement Events with respect
      to the Common Securities and the consequences thereof until all Trust
      Enforcement Events with respect to the Preferred Securities have been
      cured, waived or otherwise eliminated, and until such Trust Enforcement
      Events with respect to the Preferred Securities have been so cured, waived
      or otherwise eliminated, the Property Trustee will be deemed to be acting
<PAGE>

      solely on behalf of the Holders of the Preferred Securities and only the
      Holders of the Preferred Securities will have 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 TIA and such Sections 316(a)(1)(A)
and 316(a)(1)(B) of the TIA are hereby expressly excluded from this Trust
Agreement and the Securities, as permitted by the TIA. 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 Preferred Securities constitutes a waiver of
the corresponding Trust Enforcement Event with respect to the Preferred
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 TIA and such Section
316(a)(1)(B) of the TIA is hereby expressly excluded from this Trust Agreement
and the Securities, as permitted by the TIA.

      Section 2.7.  Notice of Trust Enforcement Event.

      If a Trust Enforcement Event occurs and is continuing with respect to the
Securities and if it is known to a Responsible Officer of the Property Trustee,
the Property Trustee shall mail to each Holder of Securities notice of a Trust
Enforcement Event within 90 days after it occurs or, if later, after a
Responsible Officer of the Property Trustee has knowledge of such Trust
Enforcement Event. Except in the case of a Trust Enforcement Event caused by a
default in payment of principal of or interest on any Debentures, the Property
Trustee may withhold the notice if and so long as its corporate trust committee
or a committee of its Responsible Officers in good faith determines that
withholding the notice is in the interests of Holders of Securities.

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

      (a) Except as expressly set forth in this Trust Agreement and except if a
meeting of the Administrative Trustees is called with respect to any matter over
which the Administrative Trustees have power to act, any power of the

which the Sponsor has determined to qualify or register such Preferred
Securities for sale; and

      (c) to acquire the Debentures with the proceeds of the sale of the

Securities and the Holders of the Common Securities or to enable the Trust to

      (o) to take any action, not inconsistent with applicable law, that the

the Trust set out in Section 3.3, and the Administrative Trustees shall have no
power to, and shall not, take any action that is inconsistent with the purposes
and functions of the Trust set forth in Section 3.3.

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

      Any expenses incurred by the Administrative Trustees pursuant to this
Section 3.6 shall be reimbursed by the Sponsor.

      (a) The Trust shall not, and none of the Trustees (including the Property
Trustee) shall cause the Trust to, engage in any activity other than as required
or authorized by this Trust Agreement. In particular, the Trust shall not and
none of the Trustees (including the Property Trustee) shall cause the Trust to:

            (i) invest any proceeds received by the Trust from holding the
      Debentures, but shall distribute all such proceeds to Holders of
      Securities pursuant to the terms of this Trust Agreement and of the
      Securities;

            (ii) acquire any assets other than as expressly provided herein;

            (iii) possess Trust property for other than a Trust purpose;

            (vii) issue any securities or other evidences of beneficial
      ownership of, or beneficial interest in, the Trust other than the

      modification 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 amendment or modification will not
      cause more than an insubstantial risk that the Trust will be deemed an
      Investment Company required to be registered under the 1940 Act, or the
      Trust will not be classified as a grantor trust for United States federal
      income tax purposes;

            (ix) take any action inconsistent with the status of the Trust as a
      grantor trust for United States federal income tax purposes; or

of the Securities. The right, title and interest of the Property Trustee to the

appointed as Property Trustee in accordance with Section 6.6. Such vesting and
cessation of title shall be effective whether or not 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 Delaware Trustee (if
the Property Trustee does not also act as Delaware Trustee).

      (c) The Property Trustee shall:

            (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 Preferred
      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.

      "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 Preferred 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) Subject to Section 3.9(b), the Property Trustee may take any Legal
Action which arises out of or in connection with a Trust Enforcement Event or
the Property Trustee's duties and obligations under this Trust Agreement or the
TIA; 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
Preferred Securities may directly institute a proceeding against the Debenture
Issuer for enforcement of payment to such Holder of the principal of (including
premium, if any) or interest (including any Additional Interest, as defined in
the Indenture) on Debentures having a principal amount equal to the aggregate
liquidation amount of the Preferred 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 Preferred
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 Preferred Security or under Section 7.3 of the Indenture.

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

            (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 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

<PAGE>

to the rights of the Holders pursuant to this Trust Agreement and the terms of
the 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 TIA. 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.  Duties and Responsibilities of the Property Trustee.

      (a) If a Trust Enforcement Event has occurred and is continuing, the
Property Trustee shall exercise 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 man would exercise or use under the circumstances in the conduct of his
own affairs.

      (b) Except during the continuance of any Trust Enforcement Event:

            (i) the Property Trustee need perform only those duties that are
      specifically set forth in this Trust Agreement and no others; and

            (ii) in the absence of bad faith on its part, the Property Trustee
      may conclusively rely, as to the truth of the statements and the
      correctness of the opinions expressed therein, upon Officers' Certificates
      or opinions of counsel furnished to the Property Trustee and conforming to
      the requirements of this Trust Agreement; however, in the case of any such
      Officer's Certificates or opinions of counsel which by any provision
      hereof are specifically required to be furnished to the Property Trustee,
      the Property Trustee shall examine such Officers' Certificates and
      opinions of counsel to determine whether or not they conform to the
      requirements of this Trust Agreement.

      (c) The Property Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

            (i) This paragraph does not limit the effect of paragraph (b) of
      this Section;

<PAGE>

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

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

      (d) Every provision of this Trust Agreement that in any way relates to the
Property Trustee is subject to paragraphs (a), (b) and (c) of this Section.

      (e) The Property Trustee may refuse to perform any duty or exercise any
right or power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

      (f) The Property Trustee shall not be liable for interest on any money
received by it except as the Property Trustee may agree in writing with the
Sponsor. Money held in trust by the Property Trustee need not be segregated from
other funds except in relation to the Property Account maintained pursuant to
Section 3.8(c)(i) and except to the extent required by law.

      (g) No provision of this Trust Agreement shall require the Property
Trustee to risk its own funds or otherwise incur any financial liability in the
performance of any of its duties, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk is not reasonably assured to it.

      (h) The Property Trustee's sole duty with respect to the custody,
safe-keeping and physical preservation of the Debentures and the Property
Account shall be to deal with such property in a similar manner as the Property
Trustee deals with similar property for its own account, subject to the
protections and limitations on liability afforded to the Property Trustee under
this Trust Agreement and the TIA.

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

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

      (a) The Property Trustee may rely on and shall be protected in acting or

reliance on such Officers' Certificate or opinion of counsel.

      (c) The Property Trustee may act through agents and shall not be
responsible for the misconduct or negligence of any agent appointed with due

omits to take in good faith which it believes to be authorized or within its
rights or powers.

the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Holders of Securities unless such Holders shall have
offered to the Property Trustee reasonable security or indemnity against the
costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction, including such reasonable advances as may be
requested by the Property Trustee; provided, that nothing contained in this
Section 3.10(f) 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 in the manner provided by
Section 3.9(a).

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

liquidation amount of the Securities as would been entitled to direct the
Property Trustee under the terms of the Securities in respect of such remedy,
right or action, (ii) may refrain from enforcing such remedy or right or taking
such other action until such instructions are received, and (iii) shall be
protected in conclusively relying on or acting in or accordance with such

connection with a bankruptcy, the expenses and the compensation for the services
are intended to constitute expenses of administration under any bankruptcy law
or law for the relief of debtors generally.

      (j) 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.

this Trust Agreement other than Section 6.2, the Delaware Trustee shall not be
entitled to exercise any powers, nor shall the Delaware Trustee have any of the
duties and responsibilities of the Administrative Trustees or the Property

any gross negligence or willful misconduct of the Delaware Trustee.

      Section 3.12.  Execution of Documents. Unless otherwise determined by the
Administrative Trustees, and except as otherwise required by the Business Trust
Act or applicable law, any Administrative Trustee is authorized to execute on

Section 8.2.

      (b) The Trust may, at the request of the Sponsor and with the consent of
the Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees and without the consent of the Holders of the
Securities, the Delaware Trustee or the Property Trustee, consolidate, merge

substantially as an entirety to a trust organized as such under the laws of any
State; provided, that:

            (i) if the Trust is not the successor, such successor entity (the
      "Successor Entity") either:

                  a. expressly assumes all of the obligations of the Trust with
            respect to the Securities; or

                  b. substitutes for the Preferred Securities other securities
            having substantially the same terms as the Preferred Securities (the
            "Successor Securities") so long as the Successor Securities rank the
            same as the Preferred Securities rank in priority with respect to
            Distributions and payments upon liquidation, redemption and
            otherwise;

            (ii) if the Trust is not the successor Entity, the Sponsor expressly
      appoints a trustee of such Successor Entity that possesses the same powers
      and duties as the Property Trustee as the holder of the Debentures;

      organization on which the Preferred Securities are then listed or quoted;

<PAGE>

            (iv) such merger, consolidation, replacement, conveyance, transfer
      or lease does not cause the Preferred Securities (including any Successor
      Securities) to be downgraded by any nationally recognized statistical

      lease does not adversely affect the rights, preferences and privileges of
      the Holders of the Preferred Securities (including any Successor
      Securities) in any material respect other than with respect to the
      dilution of the Holders' interest in the new entity;

            (vi) such Successor Entity has a purpose identical to that of the
      Trust;

            (vii) prior to such merger, consolidation, replacement, conveyance,
      transfer or lease the Sponsor has received an opinion of independent
      counsel to the Trust experienced in such matters to the effect that:

                  a. such merger, consolidation, replacement, conveyance,
            transfer or lease does not adversely affect the rights, preferences
            and privileges of the Holders of the Preferred Securities (including
            any Successor Securities) in any material respect (including any
            Successor Securities) other than with respect to the dilution of the
            Holders' interest in the new entity;

                  b. following such merger, consolidation, 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 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 Guarantee; and

            (ix) 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, 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, merge with or into, or replace it, if
such consolidation, 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 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 agents 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

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.

            (iii) after the issuance of the Preferred Securities and the
      occurrence of an Indenture Event of Default, by vote of the Holders of a
      Majority in Liquidation Amount of the Preferred Securities; provided,
      however, that the Administrative Trustees may still be appointed or
      removed without cause in such circumstance, by vote of the Holders of a
      Majority in Liquidation Amount of the Common Securities voting as a class
      at a meeting of the Holders of the Common Securities.

      (b) A Trustee may resign with respect to the Securities by so notifying
the Sponsor and the Trust. A resignation or removal of the Property Trustee or
Delaware Trustee and appointment of a successor Trustee shall become effective
only upon the successor Trustee's acceptance of appointment as provided in this

            (ii) the Trustee is adjudged a bankrupt or an insolvent or an order
      for relief is entered with respect to the Trustee under any Bankruptcy

      other similar official) takes charge of the Trustee or its property; or

            (iv) the Trustee becomes incapable of acting.

      (d) If a Trustee resigns or is removed or if a vacancy exists in the
office of a Trustee for any reason, the Holders of the Common Stock shall
promptly appoint a successor Trustee.

      (e) If a successor Property Trustee or Delaware Trustee does not take
office within 60 days after the retiring Property Trustee or Delaware Trustee,
as the case may be, resigns or is removed, the retiring Trustee, the Sponsor or
the Holders of at least 10% in Liquidation Amount of the Securities may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

      (f) If the Property Trustee fails to comply with Section 6.3, any Holder
of Securities may petition any court of competent jurisdiction for the removal
of the Property Trustee and the appointment of a successor Property Trustee.

appointment to the retiring Property Trustee and to the Trust and Sponsor.
Immediately after that, the retiring Property Trustee shall transfer all
property held by it as Property Trustee to the successor Property Trustee, the
resignation or removal of the retiring Property Trustee shall become effective,
and the successor Property Trustee shall have all the rights, powers and duties
of the Property Trustee. A successor Property Trustee shall mail a notice of its

expenses and liabilities incurred by it prior to such replacement.

      (h) A successor Delaware Trustee shall deliver a written acceptance of its
appointment to the retiring Delaware Trustee and to the Trust and Sponsor.

Trustee shall mail a notice of its succession to each Holder.

      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
<PAGE>

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.

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

representing undivided beneficial ownership interests in the assets of the
Trust.

            (i) Preferred Securities. The Preferred Securities of the Trust have

      ($__________) with respect to the second closing of the sale of Preferred
      Securities; provided that the maximum aggregate liquidation amount of
      Preferred Securities of the Trust shall not exceed ____________ dollars

      "Preferred Securities"). The Preferred Securities shall be in
      substantially the form set forth in Exhibit A to this Trust Agreement, or
      in such other form as shall be established by the Administrative Trustees,
      in each case with such appropriate insertions, omissions, substitutions
      and other variations as are required or permitted by this Trust Agreement,
      and may have such letters, numbers or other marks of identification and
      such legends or endorsements placed thereon as may be required to comply
      with the rules of any securities exchange or as may, consistent herewith,
      be determined by the Administrative Trustees executing such Preferred
      Securities, as evidenced by their execution of the Preferred Securities.

      The definitive Preferred Securities shall be printed, lithographed or
engraved on steel engraved borders or may be produced in any other manner, all
as determined by the Administrative Trustees executing such Preferred
Securities, as evidenced by their execution of such Preferred Securities.

            (ii) Common Securities. The Common Securities of the Trust shall
      have an aggregate liquidation amount with respect to the assets of the
      Trust of ____________ dollars ($_______________) with respect to the
      initial closing of the sale of Common Securities [and, if the Option set
      forth in Section 7.18(a) is
<PAGE>

      exercised, an additional aggregate liquidation amount with respect to the
      assets of the Trust of __________ dollars ($__________)] with respect to
      the second closing of the sale of Common Securities; provided that the
      maximum aggregate liquidation amount of common securities issued by the
      Trust shall not exceed __________ dollars ($___________). The Common
      Securities are hereby designated for identification purposes only as
      "____% Common Securities" (the "Common Securities" and, together with the
      Preferred Securities, the "Securities"). The Common Securities shall be in
      substantially the form set forth in Exhibit B to this Trust Agreement, or
      in such other form as shall be established by the Administrative Trustees,
      in each case with such appropriate insertions, omissions, substitutions
      and other variations as are required or permitted by this Trust Agreement,
      and may have such letters, numbers or other marks of identification and
      such legends or endorsements placed thereon as may be required to comply
      with the rules of any securities exchange or as may, consistent herewith,
      be determined by the Administrative Trustees executing such Common
      Securities, as evidenced by their execution of the Common Securities.

      The definitive Common Securities shall be printed, lithographed or
engraved on steel engraved borders or may be produced in any other manner, all
as determined by the Administrative Trustees executing such Common Securities,
as evidenced by their execution of such Common Securities.

      (b) Payment of Distributions on, and payment of the Redemption Price upon
a redemption of, the Preferred Securities and the Common Securities, as
applicable, shall be made Pro Rata based on the liquidation amount of such
Preferred 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 Preferred 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 Preferred 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 Preferred Securities then due and payable. The Trust
shall issue no securities or other interests in the assets of the Trust other
than the Preferred Securities and the Common Securities.

      (c) An Administrative Trustee shall sign the Securities for the Trust by
manual or facsimile signature.

      If an Administrative Trustee whose signature is on a Security no longer
holds that office at the time the Security is authenticated, the Security shall
nevertheless be valid.
<PAGE>

      A Security shall not be valid until authenticated by the manual signature
of the Property Trustee or an authenticating agent. The signature shall be
conclusive evidence that the Security has been authenticated under this Trust
Agreement.

      The Property Trustee shall at any time, and from time to time,
authenticate Securities for original issue in an amount not to exceed the
liquidation amounts set forth in Section 7.1(a), upon receipt by the Property
Trustee of a written order of the Trust signed by an Administrative Trustee (a
"Trust Order"). Such Trust Order may authorize authentication and delivery
pursuant to oral or electronic instructions from an Administrative Trustee,
which oral instructions shall be promptly confirmed in writing. Each Security
shall be dated the date of its authentication unless otherwise provided by a
Trust Order.

      The aggregate number of Securities outstanding at any time may not exceed
the liquidation amounts set forth in Section 7.1(a), except as provided in
Section 7.10.

      The Property Trustee shall have the right to decline to authenticate and
deliver any Securities: (a) if the Property Trustee, being advised by counsel,
determines that such action may not lawfully be taken; or (b) if the Property
Trustee in good faith by its board of directors or trustees, executive committee
or a trust committee of directors and/or vice-presidents shall determine that
such action would expose the Property Trustee to personal liability to Holders
of any Securities.

      The Property Trustee may appoint an authenticating agent acceptable to the
Trust to authenticate Securities. An authenticating agent may authenticate
Securities whenever the Property Trustee may do so. Each reference in this Trust
Agreement to authentication by the Property Trustee includes authentication by
such agent. An authenticating agent has the same rights as any registrar, paying
agent or service agent to deal with the Trust.

      (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) Except to the extent set forth in Section 9.1(b), 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 ownership interests in the assets of the Trust.

      (f) Every person, by virtue of having become a Holder or a Preferred
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, the
Guarantee, the Indenture and the Debentures.

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

      Section 7.2.  Distributions.

      (a) 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. The amount of Distributions payable for any period shall be
computed on the basis of a 360-day year of twelve 30-day months. The amount of
distributions payable for any period shorter than a full [quarterly]
[semi-annual] 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
Preferred Securities and the Common Securities on a Pro Rata basis.
Distributions on the Securities shall, from the date of original issue, accrue
and be cumulative and shall be payable [quarterly][semi-annually], in arrears,
on each __________ [, __________, _________] and _________, commencing_________
__, ____, 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) Distributions not paid on the scheduled payment date will accumulate
and compound [quarterly][semi-annually] 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, to 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 Preferred Securities are represented by
one or more Global Securities, the relevant record dates shall be the close of
business on the Business Day next preceding such Distribution payment date,
unless a different regular record date is established or provided for the
corresponding interest payment date on the Debentures. The relevant record dates
for the Common Securities shall be the same as for the Preferred Securities. If
the Preferred Securities shall not continue to remain represented by one or more
Global Securities, the relevant record dates for the Preferred Securities shall
be selected by the Administrative Trustees and shall be at least 15 days prior
to the relevant payment dates. 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 with respect to the related interest payment date pursuant to the
Indenture.

<PAGE>

      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), except that, if such Business Day
is in the next succeeding calendar year, such payment shall be made on the next
preceding day which is a Business Day, 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.

      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 Debentures and the Indenture,
including pursuant to a Special Event, 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) Certificates called for redemption in whole must be surrendered to the
Paying Agent in order to receive payment of the Redemption Price. Upon surrender
of a Security that is redeemed in part, the Property Trustee shall authenticate
for the Holder a new Security equal in liquidation amount to the unredeemed
portion of the Security surrendered.

      Section 7.4.  Redemption Procedures.

      (a) At least 30 days but not more than 60 days before a redemption date,
the Trust shall mail a notice of redemption by first-class mail to each Holder
whose Securities are to be redeemed.

      The notice shall identify the Securities to be redeemed and shall state:

            (i) the redemption date;

            (ii) the redemption price;

            (iii) the name and address of the Paying Agent;

            (iv) that Securities called for redemption must be surrendered to
      the Paying Agent to collect the redemption price;

            (v) that Distributions on Securities called for redemption cease to
      accrue on and after the redemption date; and
<PAGE>

            (vi) any other information as may be required by the terms of the
      Securities being redeemed.

      At the Trust's request, the Property Trustee shall give the notice of
redemption in the Trust's name and at its expense.

      (b) If fewer than all the outstanding Securities are to be so redeemed,
the Common Securities and the Preferred Securities will be redeemed Pro Rata
(subject to Section 7.1(b)) and will be redeemed as described in Section 7.4(c)
below. 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
Preferred Securities shall relate, in the case of any Preferred Security
redeemed or to be redeemed only in part, to the portion of the aggregate
liquidation amount of Preferred Securities which has been or is to be redeemed.

      (c) Once notice of redemption is mailed as provided in Section 7.4(a),
Securities called for redemption become due and payable on the redemption date
and at the redemption price. A notice of redemption may not be conditional. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price plus accrued Distributions to the redemption date.

      (d) On or before the redemption date; provided that the Debenture Issuer
has paid the Property Trustee a sufficient amount of immediately available funds
in connection with the related redemption of the Debentures, the Property
Trustee shall deposit with the Paying Agent money sufficient to pay the
redemption price of and accumulated and unpaid Distributions, if any, on all
Securities to be redeemed on that date.

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

      Section 7.5.  Voting Rights of Preferred Securities.

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

      (b) Subject to the requirement of the Property Trustee to obtain a tax
opinion in certain circumstances as set forth in Section 7.5(d) below, the
Holders of a Majority in Liquidation Amount of the Preferred Securities shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Property Trustee, or exercising any trust or
power conferred on 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
<PAGE>

or the Debentures where such consent shall be required or (iii) waive any past
default and its consequences that is waivable under Section 7.13 of the
Indenture; provided, however, that if an Indenture Event of Default has occurred
and is continuing, then the Holders of ___% of the aggregate liquidation amount
of the Preferred Securities may direct the Property Trustee to declare the
principal of and accrued and unpaid interest, if any, on the Debentures due and
payable immediately; 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
Preferred 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; provided, further, that (subject to the provisions of Section 3.9) the
Property Trustee shall have the right to decline to follow any such direction if
the Property Trustee shall (x) determine that the direction conflicts with any
rule of law, the Trust Agreement or the Indenture; (y) determine that the
Property Trustee may take any other action deemed proper by the Property Trustee
which is not inconsistent with such direction; and (z) in good faith, by a
Responsible Officer of the Property Trustee, determine that the proceeding so
directed would involve the Property Trustee in personal liability.

      (c) If the Property Trustee fails to enforce its rights under the
Debentures after a Holder of Preferred Securities has made a written request,
such Holder of Preferred 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 Preferred Securities may directly institute a Direct Action
against the Debenture Issuer on or after the respective due date specified in
the Debentures.

      (d) Subject to Section 2.7, the Property Trustee shall notify all Holders
of the Preferred Securities of any notice of any Indenture Event of Default
received from the Debenture Issuer with respect to the Debentures. Such notices
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 fail to be classified as a grantor
trust for United States federal income tax purposes as a result of such action,
and each Holder will be treated as owning an undivided beneficial ownership
interest in the Debentures.

      (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 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
<PAGE>

liquidation amount of the 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 other than a grantor
trust for United States federal income tax purposes as a result of such action,
and each Holder will be treated as owning an undivided beneficial ownership
interest in the Debentures.

      (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 Preferred Securities
may be given at a separate meeting of Holders of Preferred 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 Preferred Securities are entitled to vote to be
mailed to each Holder of record of Preferred 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 Preferred Securities shall be
required for the Trust to redeem and cancel Preferred Securities or distribute
Debentures in accordance with this Trust Agreement and the terms of the
Securities.

      (i) Notwithstanding that Holders of Preferred 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 Preferred
Securities may vote or consent with respect to such pledged Preferred Securities
under any of the circumstances described herein.

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

      (k) Subject to the rights of the Holders of a Majority in Liquidation
Amount of the Common Securities to appoint or remove Administrative Trustees as
provided in Section 6.6(a)(iii), if an Indenture Event of Default has occurred
and is
<PAGE>

continuing, the Trustees may be removed at such time only by a Majority in
Liquidation Amount of the Preferred 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 TIA or other
applicable law, 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 6 of this Trust
Agreement, to vote to appoint, remove or replace any Trustee or to increase or
decrease the number of Trustees.

      (c) Subject to Section 2.6 and only after all Trust Enforcement Events
with respect to the Preferred Securities have been cured, waived, or otherwise
eliminated and subject to the requirement of the Property Trustee to obtain a
tax opinion in certain circumstances as 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 exercising any trust or power
conferred on 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 7.13 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; provided, further, that (subject to the provisions of Section 3.9) the
Property Trustee shall have the right to decline to follow any such direction if
the Property Trustee shall (x) determine that the direction conflicts with any
rule of law, the Trust Agreement or the Indenture; (y) determine that the
Property Trustee may take any other action deemed proper by the Property Trustee
which is not inconsistent with such direction; and (z) in good faith, by a
Responsible Officer of the Property Trustee, determine that the proceeding so
directed would involve the Property Trustee in personal liability. 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 the Trust
will not fail to be classified as a grantor trust for United States federal
income tax purposes as a result of such action, and each Holder will be treated
as owning an undivided beneficial ownership interest in the Debentures.
<PAGE>

      (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
maybe 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 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.

      (g) No vote or consent of the Holders of the Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
Debentures in accordance with the Trust Agreement and the terms of the
Securities.

      Section 7.7.  Registrar and Paying Agent. The Trust shall cause a Paying
Agent to maintain an office or agency where the Securities may be presented or
surrendered for payment, maintain an office or agency where Securities may be
surrendered for registration of transfer or exchange ("Registrar") and where
notices and demands to or upon the Trust in respect of the Securities and this
Trust Agreement may be served ("Service Agent"). The Registrar shall keep a
register with respect to the Securities and to their transfer and exchange. The
Trust will give prompt written notice to the Property Trustee of the name and
address, and any change in the name or address, of each Registrar, Paying Agent
or Service Agent. If at any time the Trust shall fail to maintain any such
required Registrar, Paying Agent or Service Agent or shall fail to furnish the
Property Trustee with the name and address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Property Trustee, and the Trust hereby appoints the Property
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

      The Trust may also from time to time designate one or more co-registrars,
additional paying agents or additional service agents and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Trust of its obligations to maintain
a Registrar, Paying Agent and Service Agent for such purposes. The Trust will
give prompt written notice to the Property Trustee of any such designation or
rescission and of any change in the name or address of any such co-registrar,
additional paying agent or additional service agent. The term "Registrar"
includes any co-registrar; the term "Paying Agent" includes any
<PAGE>

additional paying agent; and the term "Service Agent" includes any additional
service agent.

      The Trust hereby appoints the Property Trustee the initial Registrar,
Paying Agent and Service Agent for the Securities.

      Section 7.8.  Listing. The Sponsor shall use its best efforts to cause the
Preferred Securities to be listed for quotation on the New York Stock Exchange.

      Section 7.9.  Transfer and Exchange 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, Preferred Securities shall be freely
transferable.

            (ii) Holders 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 VI 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) Where Securities are presented to the Registrar or a co-registrar with
a request to register a transfer or to exchange them for an equal liquidation
amount of Securities, the Registrar shall register the transfer or make the
exchange if its requirements for such transactions are met. To permit
registrations of transfers and exchanges, the Property Trustee shall
authenticate Securities at the Registrar's request. No service charge shall be
made for any registration of transfer or exchange (except as otherwise expressly
permitted herein), but the Trust may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer tax or similar governmental charge
payable upon exchanges pursuant to Section 7.4).

      Neither the Trust nor the Registrar shall be required (i) to issue,
register the transfer of, or exchange Securities for the period beginning at the
opening of business fifteen days immediately preceding the mailing of a notice
of redemption of Securities and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange Securities
selected, called or being called for redemption as a whole or the portion being
redeemed of any such Securities selected, called or being called for redemption
in part.
<PAGE>

      Section 7.10.  Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security is surrendered to the Property Trustee, the Administrative
Trustees shall execute and the Property Trustee shall authenticate and deliver
in exchange therefor a new Security of like tenor and liquidation amount and
bearing a number not contemporaneously outstanding.

      If there shall be delivered to the Administrative Trustees and the
Property Trustee (i) evidence to their satisfaction of the destruction, loss or
theft of any Security and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Administrative Trustees or the Property Trustee that
such Security has been acquired by a bona fide purchaser, the Administrative
Trustees shall execute and upon its request the Property Trustee shall
authenticate and make available for delivery, in lieu of any such destroyed,
lost or stolen Security, a new Security of like tenor and liquidation amount and
bearing a number not contemporaneously outstanding.

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Trust in its discretion may, instead
of issuing a new Security, pay such Security.

      Upon the issuance of any new Security under this Section, the Trust may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Property Trustee) connected therewith.

      Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Trust, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Trust Agreement equally and proportionately
with any and all other Securities duly issued hereunder.

      The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

      Section 7.11.  Outstanding Securities. The Securities outstanding at any
time are all the Securities authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation, those reductions in the
interest on a Global Security effected by the Trustee in accordance with the
provisions hereof and those described in this Section as not outstanding.

      If a Security is replaced pursuant to Section 7.10, it ceases to be
outstanding until the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

      If the Paying Agent (other than the Sponsor, a subsidiary or an Affiliate
of any thereof) holds on a redemption date of Securities money sufficient to pay
such
<PAGE>

Securities payable on that date, then on and after that date such Securities
cease to be outstanding and Distributions on them ceases to accrue.

      A Security does not cease to be outstanding because the Sponsor or an
Affiliate holds the Security.

      Section 7.12.  Treasury Securities. In determining whether the Holders of
the required liquidation amount of Preferred Securities have concurred in any
request, demand, authorization, direction, notice, consent or waiver, Preferred
Securities owned by the Sponsor or an Affiliate shall be disregarded, except
that for the purposes of determining whether the Property Trustee shall be
protected in relying on any such request, demand, authorization, direction,
notice, consent or waiver only Preferred Securities that the Property Trustee
knows are so owned shall be so disregarded.

      Section 7.13.  Temporary Securities. Until definitive Securities are ready
for delivery, the Administrative Trustees may prepare and the Property Trustee
shall authenticate temporary Securities upon a Trust Order. Temporary Securities
shall be substantially in the form of definitive Securities but may have
variations that the Administrative Trustees considers appropriate for temporary
Securities. Without unreasonable delay, the Administrative Trustees shall
prepare and the Property Trustee upon request shall authenticate definitive
Securities in exchange for temporary Securities. Until so exchanged, temporary
securities shall have the same rights under this Trust Agreement as the
definitive Securities.

      Section 7.14.  Cancellation. The Trust at any time may deliver Securities
to the Property Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Property Trustee any Securities surrendered to them for
registration of transfer, exchange or payment. The Property Trustee shall cancel
all Securities surrendered for transfer, exchange, payment, replacement or
cancellation and shall destroy such canceled Securities (subject to the record
retention requirement of the Exchange Act) and deliver a certificate of such
destruction to the Trust, unless the Trust otherwise directs. The Trust may not
issue new Securities to replace Securities that it has paid or delivered to the
Property Trustee for cancellation.

      Section 7.15.  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 subject to Section 7.2(d)
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 7.16.  Global Securities.

      Section 7.16.1  Terms of Securities. A Trust Order shall establish whether
the Preferred Securities shall be issued in whole or in part in the form of one
or more Global Securities and the Depositary for such Global Security or
Securities.
<PAGE>

      Section 7.16.2  Transfer and Exchange. Notwithstanding any provisions to
the contrary contained in Section 7.9 and in addition thereto, any Global
Security shall be exchangeable pursuant to Section 7.9 for Preferred Securities
registered in the names of Holders other than the Depositary for such Preferred
Security or its nominee only if (i) such Depositary notifies the Trust that it
is unwilling or unable to continue as Depositary for such Global Security or if
at any time such Depositary ceases to be a clearing agency registered under the
Exchange Act, and, in either case, the Trust fails to appoint a successor
Depositary within 90 days of such event, (ii) the Trust executes and delivers to
the Property Trustee an Officers' Certificate to the effect that such Global
Security shall be so exchangeable or (iii) a Trust Enforcement Event with
respect to the Preferred Securities represented by such Global Security shall
have happened and be continuing. Any Global Security that is exchangeable
pursuant to the preceding sentence shall be exchangeable for Preferred
Securities registered in such names as the Depositary shall direct in writing in
an aggregate liquidation amount equal to the liquidation amount of the Global
Security with like tenor and terms.

      Except as provided in this Section 7.16.2, a Global Security may not be
transferred except as a whole by the Depositary with respect to such Global
Security to a nominee of such Depositary, by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by the Depositary or
any such nominee to a successor Depositary or a nominee of such a successor
Depositary.

      Section 7.16.3  Legend. Any Global Security issued hereunder shall bear a
legend in substantially the following form:

      "This Security is a Global Security within the meaning of the Trust
Agreement hereinafter referred to and is registered in the name of the
Depositary or a nominee of the Depositary. This Security is exchangeable for
Preferred 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 may not be transferred except as a whole by the Depositary
to a nominee of the Depositary, 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 a successor Depositary."

      Unless this Preferred Security Certificate is presented by an authorized
representative of the Depositary to Omnicom Capital Trust __ or its agent for
registration of transfer, exchange or payment, and any Preferred 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 WRONGFUL in as much as the
registered owner hereof, Cede & Co., has an interest herein."

      Section 7.16.4  Cancellation; Issuance of Registered Securities. At such
time as all interests in Global Securities have been redeemed, repurchased or
cancelled,
<PAGE>

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 Preferred Securities not represented by a Global Security, redeemed,
cancelled or transferred to a transferee who receives Preferred Securities not
represented by a Global Security therefor or any Preferred 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 may at any time and in its sole discretion determine that the
Preferred Securities issued in the form of one or more Global Securities shall
no longer be represented by a Global Security or Preferred Securities. In such
event the Trust shall execute, and the Property Trustee, shall authenticate and
deliver, Preferred Securities in definitive registered form, in any authorized
denominations, in an aggregate liquidation amount equal to the principal amount
of the Global Security or Preferred Securities representing such Preferred
Securities, in exchange for such Global Security or Preferred Securities.

      Section 7.16.5  Acts of Holders. The Depositary, as a Holder, may appoint
agents and otherwise authorize participants to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action which a Holder
is entitled to give or take under the Trust Agreement.

      Section 7.16.6  Payments. Notwithstanding the other provisions of this
Trust Agreement, payment of the liquidation amount on any Global Security shall
be made to the Holder thereof.

      Section 7.16.7  Consents, Declaration and Directions. Except as provided
in Section 7.16.6, the Trust, the Property Trustee and any Agent shall treat a
person as the Holder of such liquidation amount of outstanding Preferred
Securities represented by a Global Security as shall be specified in a written
statement of the Depositary with respect to such Global Security, for purposes
of obtaining any consents, declarations, waivers or directions required to be
given by the Holders pursuant to this Trust Agreement.

      Section 7.17.  CUSIP Numbers. The Trust in issuing the Securities may use
"CUSIP" numbers (if then generally in use), and, if so, the Property Trustee
shall use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption and that reliance may be placed only on the other
elements of identification printed on the Securities, and any such redemption
shall not be affected by any defect in or omission of such numbers.
<PAGE>

      SECTION 7.18.  Over-Allotment Option.

      (a) The Administrative Trustees, on behalf of the Trust, and the Sponsor
may grant to the underwriters or initial purchasers who are underwriting or
purchasing, as the case may be, any series of Preferred Securities, an option
(the "Option") to purchase an additional liquidation amount of such series of
Preferred Securities on the terms and conditions specified in the underwriting
agreement or purchase agreement, as the case may be, relating to such Preferred
Securities; provided, however, the Option may only be granted if the following
conditions are satisfied:

            (i) the Option, if exercised, may not result in the issue and sale
      of an aggregate liquidation amount of Preferred Securities greater than
      that registered by the Sponsor and the Trust on the applicable
      registration statement or registration statements (including by a
      registration statement filed under Rule 462(b) under the Securities Act,
      if any), as the case may be, with the Commission under the Securities Act;

            (ii) the Option must result, if exercised, in the issuance and sale
      of Preferred Securities to such underwriters or initial purchasers, as the
      case may be, and the issuance and sale of Common Securities to the Sponsor
      on a Pro Rata basis and not in contravention of any other provision of
      this Agreement or the Business Trust Act, consistent with Section 5.1; and

            (iii) the Preferred Securities and the Common Securities issued and
      sold subject to the exercise of the Option, if any, must be of the same
      series and must bear the same CUSIP numbers as the series of Preferred
      Securities and the Common Securities, respectively, which were initially
      issued and sold by the Trust and the Sponsor, respectively.

      (b) With respect to any issuance of Preferred Securities and Common
Securities following the exercise of the Option,

            (i) the designation the "__% Preferred Securities" and, for all
      purposes under this Trust Agreement, the defined terms the "Preferred
      Securities" shall mean both the Preferred Securities issued initially
      hereunder and any Preferred Securities issued pursuant to the exercise of
      the Option; and

            (ii) the designation the "__% Common Securities" and, for all
      purposes under this Trust Agreement, the defined term the "Common
      Securities" shall mean both the Common Securities issued initially
      hereunder and any Common Securities issued pursuant to the requirement of
      Section 7.18(a)(ii) regarding the additional issuance of Common Securities
      on a Pro Rata basis if the Option is exercised.

      (c) If the Option set forth in Section 7.18(a) is exercised on a date
other than the initial Closing Date, then the parties to the Trust Agreement
shall cause there to occur a second closing for the consummation of the sale of
the Preferred
<PAGE>

Securities and Common Securities under substantially the same conditions that
applied to the initial closing of the sale of such securities, including the
following:

            (i) the execution and delivery of a second Preferred Security
      Certificate, or such additional Preferred Security Certificates, as
      appropriate, which is, or are, as the case may be, substantially identical
      in all respects to the Preferred Security Certificate issued initially;
      and

            (ii) the execution and delivery of a second Common Security
      Certificate, or such additional Common Security Certificate, as
      appropriate, which is, or are, as the case may be, substantially identical
      in all relevant respects to the Common Security Certificate issued
      initially.

                      DISSOLUTION AND TERMINATION OF TRUST

      Section 8.1.  Dissolution and Termination of Trust.

            (i) the Bankruptcy Event of the Holder of the Common Securities or

            (ii) the filing of a certificate of dissolution or its equivalent
      with respect to the Sponsor; after obtaining the consent of the Holders of

      of 90 days after the date of 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 to the Holders of the
      Securities in exchange for all of the Securities; provided that the
      Sponsor will be required to obtain an opinion of an independent counsel
      that the distribution of the Debentures will not be taxable to the Holders
      of the Preferred 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.
<PAGE>

      (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 Trusts' 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
accrued and unpaid interest equal to accumulated 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 Preferred Securities except that if
an Indenture Event of Default has occurred and is continuing, the Preferred
Securities shall have a preference over the Common Securities with regard to
such distributions.

                                   ARTICLE 9

                           LIMITATION OF LIABILITY OF

      Section 9.1.  Liability.

      (a) Except as expressly set forth in this Trust Agreement, the Guarantee

      (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

      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) (i) 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 Debentures 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
<PAGE>

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.

            (ii) 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 Debentures
      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, except that no such indemnification shall be made
      in respect of any claim, issue or matter as to which such Debentures
      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.

            (iii) Any indemnification under paragraphs (i) and (ii) of this
      Section 9.4(a) (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 Debentures Issuer Indemnified Person is proper in
      the circumstances because he has met the applicable standard of conduct
      set forth in paragraphs (i) and (ii). 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
      Holders of the Common Securities of the Trust.

            (iv) Expenses (including attorneys' fees) incurred by a Debentures
      Issuer Indemnified Person in defending a civil, criminal, administrative
      or investigative action, suit or proceeding referred to in paragraphs (i)
      and (ii) of this Section 9.4(a) shall be paid by the Debenture Issuer in
      advance of the final disposition of such action, suit or proceeding upon
      receipt of an undertaking by or on behalf of such Debentures 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(a). Notwithstanding the
      foregoing, no advance shall be made by the Debenture Issuer if a
      determination is reasonably and promptly made (i) by the Administrative
      Trustees by a majority vote of a quorum of disinterested Administrative
      Trustees, (ii) 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 (iii) the Common
      Security Holder of the Trust, that, based upon the facts known to the
<PAGE>

      Administrative Trustees, counsel or the Common Security Holder at the time
      such determination is made, such Debentures 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 Debentures 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 Preferred Security Holders.

            (v) The indemnification and advancement of expenses provided by, or
      granted pursuant to, the other paragraphs of this Section 9.4(a) 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 Preferred 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(a) shall be deemed to be provided by a contract between
      the Debenture Issuer and each Debentures Issuer Indemnified Person who
      serves in such capacity at any time while this Section 9.4(a) is in
      effect. Any repeal or modification of this Section 9.4(a) shall not affect
      any rights or obligations then existing.

            (vi) The Debenture Issuer or the Trust may purchase and maintain
      insurance on behalf of any person who is or was a Debentures 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(a).

            (vii) For purposes of this Section 9.4(a), 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(a) with respect to the
      resulting or surviving entity as he would have with respect to such
      constituent entity if its separate existence had continued.

            (viii) The indemnification and advancement of expenses provided by,
      or granted pursuant to, this Section 9.4(a) shall, unless otherwise
      provided when authorized or ratified, continue as to a person who has
      ceased to be a Debentures Issuer Indemnified Person and shall inure to the
      benefit of the heirs, executors and administrators of such a person. The
      obligation to indemnify as set forth in this Section 9.4(a) shall survive
      the resignation or removal of the
<PAGE>

      Delaware Trustee or the Property Trustee or the termination of this Trust
      Agreement.

      (b) The Debenture Issuer agrees to indemnify the (i) Property Trustee,
(ii) the Delaware Trustee and (iii) any officers, directors, employees,
shareholders or agents of the Property Trustee or the Delaware Trustee (each of
the Persons in (i) through (iii) being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any loss, liability or expense incurred without negligence or willful misconduct
on its part, arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder, including the costs and
expenses (including reasonable legal fees and expenses) of defending itself
against or investigating any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. The obligation to
indemnify as set forth in this Section 9.4(b) shall survive the resignation and
removal of the Delaware Trustee or the Property Trustee and the dissolution of
the Trust and the termination of this Trust Agreement. In addition, the
Debenture Issuer has agreed in the Indenture to pay the fees and expenses of the
Delaware Trustee and the Property Trustee.

      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.

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

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.

      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

      setting forth the action so taken is signed by the Holders of
<PAGE>

Securities owning not less than the minimum amount of Securities in liquidation

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;

      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 TIA or the listing rules of any stock exchange on
      which the Preferred 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
