are required by Section 313 of the Trust Indenture Act, if any, in the form and
in the manner provided by Section 313 of the Trust Indenture Act. The Property
Trustee also shall comply with the requirements of Section 313(d) of the Trust
Indenture Act.

SECTION 2.4 PERIODIC REPORTS TO THE PROPERTY TRUSTEE.

     Each of the Sponsor and the Administrative Trustees on behalf of the Trust
shall provide to the Property Trustee such documents, reports and information as

form, in the manner and at the times required by Section 314 of the Trust
Indenture Act.

SECTION 2.5 EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

     Each of the Sponsor and the Administrative Trustees on behalf of the Trust

certificate or opinion required to be given by an officer pursuant to Section
314(c)(1) of the Trust Indenture Act may be given in the form of an Officers'

SECTION 2.6 TRUST ENFORCEMENT EVENTS; WAIVER.

     (a) The Holders of a Majority in Liquidation Amount of the Preferred
Securities may waive, by vote or written consent, on behalf of the Holders of
all of the Preferred Securities, any past Trust Enforcement Events 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 related Trust Enforcement
     Event under this Trust Agreement also shall not be waivable; or

          (ii) requires the vote or consent of the holders of greater than a
     majority in aggregate principal amount of the Debentures (a "Super
     Majority") to be waived under the Indenture, the related Trust Enforcement
     Event under this Trust Agreement only may be waived by the vote or written
     consent of the Holders of at least the proportion in aggregate 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 Trust Indenture Act and Section 316(a)(1)(B) of the Trust
Indenture Act is hereby expressly excluded from this Trust Agreement and the
Securities, as permitted by the Trust Indenture Act. Upon such waiver, any such
Trust Enforcement Event in respect of the Preferred Securities arising therefrom
shall be deemed to have been cured for every purpose of this Trust Agreement,

                                       17
<PAGE>

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 also shall 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 waive, by vote or written consent, on behalf of the Holders of
all of the Common Securities, any past Trust Enforcement Event in respect of the
Common Securities and its consequences, provided that, if the underlying
Indenture Event of Default is not waivable under the Indenture, except where the
Holders of the Common Securities are deemed to have waived such Trust
Enforcement Event as provided below in this Section 2.6(b), the related Trust
Enforcement Event under this Trust Agreement also shall not be waivable. The
Holders of Common Securities shall be deemed to have waived any 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. Until all Trust
Enforcement Events in respect of the Preferred Securities shall have been so
cured, waived or otherwise eliminated, the Property Trustee shall be deemed to
be acting solely on behalf of the Holders of the Preferred Securities and only
the Holders of the Preferred Securities shall 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 Section
316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act, and Sections
316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby expressly
excluded from this Trust Agreement and the Securities, as permitted by the Trust
Indenture Act. Subject to the foregoing provisions of this Section 2.6(b), upon
such cure, waiver or other elimination, any such default shall cease to exist
and any Trust Enforcement Event with respect to the Common Securities arising
therefrom shall be deemed to have been cured for every purpose of this Trust
Agreement, but no such waiver shall extend to any subsequent or other default or
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 related Trust Enforcement Event under this Trust Agreement. The foregoing
provisions of this Section 2.6(c) shall be in lieu of Section 316(a)(1)(B) of
the Trust Indenture Act, and Section 316(a)(1)(B) of the Trust Indenture Act is
hereby expressly excluded from this Trust Agreement and the Securities, as
permitted by the Trust Indenture Act.

SECTION 2.7 TRUST ENFORCEMENT EVENTS; NOTICE.

     (a) The Property Trustee shall, within 90 days after the occurrence of a
Trust Enforcement Event actually known to a Responsible Officer, transmit by
mail, first class postage prepaid, to the Holders, notice of such Trust
Enforcement Event unless such Trust Enforcement Event has been cured before the
giving of such notice; provided that, except for a default in the payment of
principal of (or premium, if any) or interest on any of the Debentures, the
Property

                                       18
<PAGE>

Trustee shall be protected in withholding such notice if and so long as a
Responsible Officer in good faith determines that the withholding of such notice
is in the interests of the Holders.

     (b) The Property Trustee shall not be deemed to have knowledge of any Trust
Enforcement Event except for:

          (i) a default under Sections 2.10(a) and 2.10(b) of the Indenture; or

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

                                       19
<PAGE>

constitute the act of and shall serve to bind the Trust. In dealing with the
Trustees acting on behalf of the Trust, no Person shall be required to inquire
into the authority of the Trustees to bind the Trust. Persons dealing with the
Trust are entitled to rely conclusively on the power and authority of the
Trustees as set forth in this Trust Agreement.

     (b) 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

such Administrative Trustee.

undivided beneficial interest in the assets of the Trust.

SECTION 3.6 PROHIBITION OF ACTIONS BY THE TRUST AND THE TRUSTEES.

        The Trust shall not, and the Trustees (including the Property Trustee

Delaware Trustee) shall cause the Trust not to:

     pursuant to the terms of this Trust Agreement and of the Securities;

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

          (iii) possess any power or otherwise act in such a way as to vary the

     expressly authorized in this Trust Agreement or by the terms of the
     Securities);

                                       20

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

          Indenture or the Debentures where such consent shall be required,
          unless the Trust shall have received an opinion of a nationally
          recognized independent tax counsel experienced in such matters to the
          effect that such amendment, modification or termination will not cause
          more than an insubstantial risk that the Trust will not be classified
          as a grantor trust for United States federal income tax purposes;

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

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

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

     actual knowledge; or

          (ii) the Property Trustee's duties and obligations under this Trust
     Agreement or the Trust Indenture Act;

provided however, that if a Trust Enforcement Event has occurred and is
continuing and such Trust Enforcement Event is attributable to the failure of
the Debenture Issuer to pay the principal of or premium, if any, or interest on
the Debentures on the date such principal, premium, if any, or interest is
otherwise payable (or in connection with a distribution of Debentures in
exchange for Preferred Securities and repurchase of Debentures under Sections
6.7 and 6.8), a Holder of Preferred Securities may institute a proceeding
directly against the Debenture Issuer to enforce payment to such Holder of the
principal of or premium, if any, or interest on the Debentures having an
aggregate 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. In connection with such Direct
Action, the Holders of the Common Securities will be subrogated to the rights of
such Holder of Preferred Securities to the extent of any payment made by the
Debenture Issuer to such Holder of Preferred Securities in such Direct Action.
Except as provided in the preceding sentences, the Holders of Preferred
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures.

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

     (i) The Property Trustee shall be authorized to undertake any actions set

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

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

                                       25
<PAGE>

          (i) prior to the occurrence of a Trust Enforcement Event and after the
     cure or waiver of all such Trust Enforcement Events that may have occurred:

               (A) the duties and obligations of the Property Trustee shall be
          determined solely by the express provisions of this Trust Agreement
          and in the Securities, and the Property Trustee shall not be liable
          except for the performance of such duties and obligations as are
          specifically set forth in this Trust Agreement and in the Securities,
          and no implied covenants or obligations shall be read into this Trust
          Agreement against the Property Trustee; and

               (B) in the absence of bad faith on the part of the Property
          Trustee, the Property Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Property
          Trustee and conforming to the requirements of this Trust Agreement;
          provided, however, that in the case of any such certificates or
          opinions that by any provision hereof are specifically required to be
          furnished to the Property Trustee, the Property Trustee shall be under
          a duty to examine such certificates or opinions to determine whether
          or not they conform to the requirements of this Trust Agreement (but
          need not confirm or investigate the accuracy of mathematical
          calculations or other facts stated therein);

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

          (iii) the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it without negligence, 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;

          (iv) no provision of this Trust Agreement shall require the Property
     Trustee to expend or risk its own funds or otherwise incur personal
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers;

          (v) the Property Trustee's (or the Paying Agent'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 (or the Paying Agent) deals with
     similar property for its own account, subject to the protections and
     limitations on liability afforded to the Property Trustee (or the Paying
     Agent) under this Trust Agreement and the Trust Indenture Act;

          (vi) 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;

                                       26
<PAGE>

          (vii) the Property Trustee (or the Paying Agent) shall not be liable
     for any interest on any money received by it except as it may otherwise
     agree in writing with the Sponsor, and money held by the Property Trustee
     (or the Paying Agent) need not be segregated from other funds held by it
     except in relation to the Property Account maintained by the Paying Agent
     pursuant to Section 3.8(c) and except to the extent otherwise required by
     law; and

          (viii) 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.

SECTION 3.10 CERTAIN RIGHTS OF THE PROPERTY TRUSTEE.

     (a) Subject to the provisions of Section 3.9:

          (i) the Property Trustee may conclusively rely and shall be fully
     protected in acting or refraining from acting upon any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     direction, consent, order, bond, debenture, note, other evidence of
     indebtedness or other paper or document believed by it to be genuine and to
     have been signed, sent or presented by the proper party or parties;

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

          (iii) whenever in the administration of this Trust Agreement, the
     Property Trustee shall deem it desirable that a matter be proved or
     established before taking, suffering or omitting any action hereunder, the
     Property Trustee (unless other evidence is herein specifically prescribed)
     may request, in the absence of bad faith on its part, and conclusively rely
     upon an Officers' Certificate which, upon receipt of such request, shall be
     promptly delivered by the Sponsor or the Administrative Trustees;

          (iv) the Property Trustee shall have no duty to see to any recording,
     filing or registration of any instrument (including any financing or
     continuation statement or any filing under tax or securities laws) or any
     rerecording, refiling or registration thereof;

          (v) the Property Trustee may consult with counsel or other experts of
     its selection and the advice or opinion of such counsel and experts with
     respect to legal matters or advice within the scope of such experts' area
     of expertise shall be full and complete authorization and protection in
     respect of any action taken, suffered or omitted by it hereunder in good
     faith and in accordance with such advice or opinion. Such counsel may be
     counsel to the Sponsor or any of its Affiliates and may include any of its
     employees. The Property Trustee shall have the right at any time to seek
     instructions concerning the administration of this Trust Agreement from any
     court of competent jurisdiction;

                                       27
<PAGE>

          (vi) the Property Trustee shall be under no obligation to exercise any
     of the rights or powers vested in it by this Trust Agreement at the request
     or direction of any Holder, unless such Holder shall have provided to the
     Property Trustee security and indemnity, reasonably satisfactory to the
     Property Trustee, against the costs, expenses (including reasonable
     attorneys' fees and expenses and the expenses of the Property Trustee's
     agents, nominees or custodians) and liabilities that might be incurred by
     it in complying with such request or direction, including such reasonable
     advances as may be requested by the Property Trustee; provided, that,
     nothing contained in this Section 3.10(a)(vi) shall be taken to relieve the
     Property Trustee, upon the occurrence of an Indenture Event of Default, of
     its obligation to exercise the rights and powers vested in it by this Trust
     Agreement;

          (vii) the Property Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     direction, consent, order, bond, debenture, note, other evidence of
     indebtedness or other paper or document, but the Property Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it sees fit;

          (viii) the Property Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     agents, custodians, nominees or attorneys, and the Property Trustee shall
     not be responsible for any misconduct or negligence on the part of any
     agent or attorney appointed with due care by it hereunder;

          (ix) any action taken by the Property Trustee or its agents hereunder
     shall bind the Trust and the Holders, and the signature of the Property
     Trustee or its agents alone shall be sufficient and effective to perform
     any such action, and no third party shall be required to inquire as to the
     authority of the Property Trustee to so act or as to its compliance with
     any of the terms and provisions of this Trust Agreement, both of which
     shall be conclusively evidenced by the Property Trustee's or its agent's
     taking such action;

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

               (A) may request instructions from the Holders which instructions
          may only be given by the Holders of the same proportion in liquidation
          amount of the Securities as would be entitled to direct the Property
          Trustee under the terms of the Securities in respect of such remedy,
          right or action;

               (B) may refrain from enforcing such remedy or right or taking
          such other action until such instructions are received; and

               (C) shall be protected in conclusively relying on or acting in
          accordance with such instructions;

                                       28
<PAGE>

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

          (xii) with respect to the calculation of the Accreted Value, the
     Property Trustee may conclusively rely upon the calculation thereof
     determined by the Calculation Agent; and

          (xiii) the Property Trustee shall not be liable for any action taken,
     suffered, or omitted to be taken by it without negligence, in good faith
     and reasonably believed by it to be authorized or within the discretion,
     rights or powers conferred upon it by this Trust Agreement.

     (b) No provision of this Trust Agreement shall be deemed to impose any duty
or obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts, or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Property Trustee shall be
construed to be a duty.

SECTION 3.11 POWERS AND DUTIES OF THE DELAWARE TRUSTEE.

     Notwithstanding any other provision of this Trust Agreement other than
Section 5.2, the Delaware Trustee shall not be entitled to exercise any powers
of, nor shall the Delaware Trustee have any of the duties and responsibilities
of, the Administrative Trustees or the Property Trustee described in this Trust
Agreement. Except as set forth in Section 5.2, the Delaware Trustee shall be a
Trustee for the sole and limited purpose of fulfilling the requirements of
Section 3807 of the Delaware Business Trust Act.

SECTION 3.12 NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

     The recitals contained in this Trust Agreement and the Securities shall be
taken as the statements of the Sponsor, and the Trustees do not assume any
responsibility for their correctness. The Trustees make no representations as to
the value or condition of the property of the Trust or any part thereof. The
Trustees make no representations as to the validity or sufficiency of this Trust
Agreement, the Securities, the Debentures or the Indenture.

SECTION 3.13 DURATION OF THE TRUST.

     The Trust, unless dissolved or terminated pursuant to the provisions of
Article VIII, shall have existence up to January 14, 2032.

SECTION 3.14 MERGERS, CONSOLIDATIONS, CONVERSIONS, AMALGAMATIONS OR REPLACEMENTS
             OF THE TRUST.

     (a) The Trust may not merge with or into, consolidate with, convert into,
amalgamate with, be replaced by or convey, transfer or lease its properties and
assets as an entirety or

                                       29
<PAGE>

substantially as an entirety to, any Person, except as described in Section
3.14(b) and 3.14(c) or Section 8.2.

     (b) 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, the Delaware
Trustee or the Property Trustee, the Trust may merge with or into, consolidate
with, convert into, amalgamate with, be replaced by or convey, transfer or lease
its properties and assets as an entirety or 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 entity, 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 Securities other securities having
          substantially the same terms as the Securities (the "Successor
          Securities"), so long as the Successor Securities rank the same as the
          Securities rank 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 the Successor Entity that possesses the same powers
     and duties as the Property Trustee as the holder of the Debentures;

          (iii) the Successor Securities are, or upon notification of issuance
     will be, listed (or eligible for trading) on any national securities
     exchange or with any other organization on which the Preferred Securities
     are listed or quoted (or otherwise eligible for trading) prior to such
     merger, consolidation, conversion, amalgamation, replacement, conveyance,
     transfer or lease;

          (iv) if the Preferred Securities (including any Successor Securities)
     are rated by any nationally recognized statistical rating organization
     prior to such transaction, such merger, consolidation, conversion,
     amalgamation, replacement, conveyance, transfer or lease does not cause the
     Preferred Securities (including any Successor Securities) to be downgraded
     by any nationally recognized statistical rating organization;

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

          (vi) such Successor Entity has a purpose substantially identical in
     all material respects to that of the Trust;

          (vii) prior to such merger, consolidation, conversion, amalgamation,
     replacement, conveyance, transfer or lease, the Sponsor has received an
     Opinion of

                                       30
<PAGE>

     Counsel to the Trust, rendered by an independent law firm experienced in
     such matters, to the effect that:

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

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

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

          (viii) if the Trust is not the successor entity, the Sponsor or any
     permitted successor or assignee owns all of the common securities of such
     Successor Entity and guarantees the obligations of such Successor Entity
     under the Successor Securities at least to the extent provided by the
     Guarantee; and (ix) the Successor Entity expressly assumes all of the
     obligations of the Trust.

     (c) Notwithstanding Section 3.14(b), the Trust shall not, except with the
consent of Holders of 100% in aggregate liquidation amount of the Securities,
merge with or into, consolidate with, convert into, amalgamate with, be replaced
by, or convey, transfer or acquire by conveyance, transfer or lease its
properties and assets as an entirety or substantially as an entirety to, any
other Person or permit any other Person to merge with or into, consolidate with,
convert into, amalgamate with, replace it, acquire by conveyance, transfer or
lease its properties and assets as an entirety or substantially as an entirety,
if such merger, consolidation, conversion, amalgamation, replacement,
conveyance, transfer or lease would cause the Trust or the Successor Entity to
be classified as other than a grantor trust for United States federal income tax
purposes or would cause each Holder of Preferred Securities not to be treated as
owning an undivided beneficial interest in the Debentures.

SECTION 3.15 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 are then due and payable as therein expressed or by Trust
Agreement or otherwise and irrespective of whether the Property Trustee has 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 to:

                                       31
<PAGE>

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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee consents 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 contained herein 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 or to authorize the Property Trustee to
vote in respect of the claim of any Holder in any such proceeding.

                                   ARTICLE IV
                                     SPONSOR

SECTION 4.1 RESPONSIBILITIES OF THE SPONSOR.

     In connection with the issue and sale of the Preferred Securities, the
Sponsor shall have the exclusive right and responsibility to engage in the
following activities:

     (a) to determine the states in which to take appropriate action to qualify
or register for sale all or part of the Preferred Securities and to do any and
all such acts, other than actions which must be taken by the Trust, and advise
the Trust of actions it must take, and prepare for execution and filing any
documents to be executed and filed by the Trust, as the Sponsor deems necessary
or advisable in order to comply with the applicable laws of any such states; and

     (b) if the Preferred Securities are separately traded from the Units and
the applicable exchange listing requirements are met, to prepare for execution
and filing by the Trust an application to permit the Preferred Securities to
trade or be quoted or listed in or on the New York Stock Exchange or any other
national securities exchange, quotation system or the Nasdaq National Market for
listing or quotation upon notice of issuance of the Preferred Securities.

SECTION 4.2 INDEMNIFICATION AND EXPENSES OF THE TRUSTEES.

     The Sponsor, in its capacity as Debenture Issuer, agrees to indemnify the
Property Trustee and the Delaware Trustee for, and to hold each of them harmless
against, any loss,

                                       32
<PAGE>

liability or expense incurred without negligence or bad faith on the part of the
Property Trustee or the Delaware Trustee, as the case may be, arising out of or
in connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses of defending either of them against
any claim or liability in connection with the exercise or performance of any of
their respective powers or duties hereunder. The provisions of this Section 4.2
shall survive the resignation or removal of the Delaware Trustee or the Property
Trustee and the termination of this Trust Agreement.

SECTION 4.3 RIGHT TO PROCEED.

     The Sponsor acknowledges the rights of the Holders of Preferred Securities,
in the event that a failure of the Trust to pay Distributions on the Preferred
Securities is attributable to the failure of the Debenture Issuer to pay
interest or principal on the Debentures, to institute a Direct Action against
the Debenture Issuer for enforcement of its payment obligations on the
Debentures.

                                    ARTICLE V

          and the proceeds thereof distributed to the Holders; and

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

     (d) The Holders of the Common Securities or, if a Trust Enforcement Event
shall have occurred and be continuing after the issuance of the Securities, the
Holders of the Preferred Securities, shall use their best efforts to promptly
appoint a Successor Property Trustee or Successor Delaware Trustee, as the case
may be, if the Property Trustee or the Delaware Trustee delivers an instrument
of resignation in accordance with this Section 5.6.

     (e) If no Successor Property Trustee or Successor Delaware Trustee, as the
case may be, shall have been appointed and accepted appointment as provided in
this Section 5.6 within 30 days after delivery of an instrument of resignation
or removal, the Property Trustee or Delaware Trustee resigning or being removed,
as applicable, may at the expense of the Sponsor petition any court of competent
jurisdiction for appointment of a Successor Property Trustee or Successor
Delaware Trustee, as applicable. Such court may thereupon, after prescribing
such notice, if any, as it may deem proper and prescribe, appoint a Successor
Property Trustee or Successor Delaware Trustee, as the case may be.

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

SECTION 5.7 VACANCIES AMONG TRUSTEES.

     If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees is
increased pursuant to Section 5.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by the

                                       36
<PAGE>

Administrative Trustees or, if there are more than two, a majority of the
Administrative Trustees shall be conclusive evidence of the existence of such
vacancy. The vacancy shall be filled with a Trustee appointed in accordance with
Section 5.6.

SECTION 5.8 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 dissolve, terminate or annul the Trust or terminate this Trust
Agreement. 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 5.6, the Administrative Trustees in office,
regardless of their number, shall have all the powers granted to the
Administrative Trustees and shall discharge all the duties imposed upon the
Administrative Trustees by this Trust Agreement.

SECTION 5.9 MEETINGS.

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

SECTION 5.10 DELEGATION OF POWER BY THE ADMINISTRATIVE TRUSTEES.

     (a) Any Administrative Trustee may, by power of attorney consistent with
applicable law, delegate to any other natural person over the age of 21 his
power for the purpose of executing any documents which the Administrative
Trustees have power and authority to cause the Trust to execute pursuant to
Section 3.7.

     (b) The Administrative Trustees shall have power to delegate from time to
time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or

                                       37
<PAGE>

otherwise as the Administrative Trustees may deem expedient, to the extent such
delegation is not prohibited by applicable law or contrary to the provisions of
the Trust, as set forth herein.

SECTION 5.11 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person, as the case may be, may be
merged or converted or with which such Trustee may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which such
Trustee shall be a party, or any Person succeeding to all or substantially all
the corporate trust business of such Trustee, shall be the successor of such
Trustee under this Trust Agreement without the execution or filing of any paper
or any further act on the part of any of the parties hereto, provided such
Person shall be otherwise qualified and eligible under this Article V.

                                   ARTICLE VI
                                 THE SECURITIES

SECTION 6.1 GENERAL PROVISIONS REGARDING THE SECURITIES.

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

          (i) The Preferred Securities of the Trust shall number 3,500,000 (or
     4,000,000 if the Managing Underwriter's over-allotment option with respect
     to the Units is exercised in full) and shall have an aggregate stated
     liquidation amount with respect to the assets of the Trust of $175,000,000
     (or $200,000,000 if the Managing Underwriter's over-allotment option with
     respect to the Units is exercised in full), a stated liquidation amount
     with respect to the assets of the Trust of $50 per Preferred Security and
     an accreted value at any time equal to the Accreted Value. The Preferred
     Securities are hereby designated for the purposes of identification only as
     the Preferred Securities. The Preferred Securities Certificates evidencing
     the Preferred Securities shall be substantially in the form of Exhibit A,
     with such changes and additions thereto or deletions therefrom as may be
     required by ordinary usage, custom or practice.

          (ii) The Common Securities of the Trust shall number 108,248 (or
     123,712 if the Managing Underwriter's over-allotment option with respect to
     the Units is exercised in full) and shall have an aggregate liquidation
     amount with respect to the assets of the Trust of $5,412,400 (or $6,185,600
     if the Managing Underwriter's over-allotment option with respect to the
     Units is exercised in full), a stated liquidation amount with respect to
     the assets of the Trust of $50 per Common Security and an accreted value at
     any time equal to the Accreted Value. The Common Securities are hereby
     designated for the purposes of identification only as the Common
     Securities. The Common Securities Certificates evidencing the Common
     Securities shall be substantially in the form of Exhibit B, with such
     changes and additions thereto or deletions therefrom as may be required by
     ordinary usage, custom or practice.

                                       38
<PAGE>

          (b) 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.

          (c) 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 nonassessable beneficial interests in the assets of the
     Trust.

          (d) Each 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, the Guarantee, the
     Indenture and the Debentures.

          (e) Payment of Distributions on, and any payment of the Redemption
     Price upon a redemption of, the Securities shall be made on a Pro Rata
     basis based on the liquidation amount of such Securities; provided that if,
     on any date on which payment of a Distribution or the Redemption Price is
     to be made, an Indenture Event of Default has occurred and is continuing,
     then such payment shall not be made on 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, until all accumulated
     and unpaid Distributions or payments of the Redemption Price, as the case
     may be, on all of the outstanding Preferred Securities for which
     Distributions are to be paid or that have been called for redemption, as
     the case may be, are fully paid. 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.

          (f) The Holders of the Securities shall not have any preemptive or
     similar rights.

SECTION 6.2 EXECUTION AND AUTHENTICATION.

     (a) Each Certificate shall be signed on behalf of the Trust by an
Administrative Trustee by manual or facsimile signature. If any Administrative
Trustee of the Trust who shall have signed any of the Securities shall cease to
be such Administrative Trustee before the Securities so signed shall be
delivered by the Trust, such Securities nevertheless may be delivered as though
the person who signed such Securities had not ceased to be such Administrative
Trustee; and any Securities may be signed on behalf of the Trust by such persons
who, at the actual date of execution of such Security, shall be the
Administrative Trustees of the Trust, although at the date of the execution and
delivery of this Trust Agreement any such person was not such an Administrative
Trustee.

     (b) A Preferred Securities Certificate shall not be valid until
authenticated by the manual or facsimile signature of an authorized signatory of
the Property Trustee. The signature shall be conclusive evidence that such
Preferred Securities Certificate has been authenticated under this Trust
Agreement.

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

                                       39
<PAGE>

number of Preferred Securities outstanding at any time shall not exceed the
aggregate stated liquidation amount set forth in Section 6.1(a)(i).

     The Property Trustee shall have the right to decline to authenticate and
deliver any Securities under this Section if the Property Trustee, being advised
by counsel, determines that such action may not lawfully be taken or if the
Trustee in good faith shall determine that such action would expose the Property
Trustee to personal liability to existing Holders.

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

     The Bank of New York is hereby appointed as the initial Authenticating
Agent.

SECTION 6.3 FORM AND DATING.

     The Preferred Securities shall be substantially in the form of Exhibits A
and the Common Securities shall be substantially in the form of Exhibit B. The
Property Trustee's certificate of authentication shall be substantially in the
form set forth in Exhibit A.

     The terms and provisions of the Securities set forth in Exhibits A and B
are part of the terms of this Trust Agreement and to the extent applicable, the
Property Trustee, the Authenticating Agent and the Sponsor, by their execution
and delivery of this Trust Agreement, expressly agree to such terms and
provisions and to be bound thereby.

     The Certificates shall be printed, lithographed or engraved or may be
produced in any other manner as is reasonably acceptable to the Administrative
Trustees, as evidenced by their execution thereof. The Certificates may have
letters, CUSIP or other numbers, notations or other marks of identification or
designation and such legends or endorsements as the Administrative Trustees may
deem appropriate, or as may be required by law, stock exchange rule, agreements
to which the Trust is subject, if any, or usage (provided that any such
notation, legend or endorsement is in a form acceptable to the Trust).

     Each Security shall be dated the date of its authentication.

     Upon the execution and delivery of this Trust Agreement, the Preferred
Securities shall be issued as a component of a Unit, in fully registered form
without Distribution coupons (the "Global Unit Certificate"), substantially in
the forms set forth in Exhibit A of the Unit Agreement. The Preferred Securities
also initially shall be issued in the forms of one or more global Certificates
in fully registered form without Distribution coupons and with the appropriate
global legends (each, a "Global Preferred Security"), substantially in the forms
of Exhibit A. The Global Preferred Securities shall be registered in the name of
the Clearing Agency or a nominee of the Clearing Agency, duly executed by the
Trust and authenticated by the Property Trustee, and deposited on behalf of the
purchasers of the Preferred Securities represented thereby with the Paying
Agent, at the Corporate Trust Office, as custodian for the Clearing Agency. The

                                       40
<PAGE>

Global Preferred Securities shall represent such of the outstanding Preferred
Securities as shall be specified in the "Schedule of Increases or Decreases in
Global Preferred Security" attached thereto (or on the books and records of the
Property Trustee and the Clearing Agency or its nominee). The Global Preferred
Securities shall initially represent no Preferred Securities. Thereafter, the
number of Preferred Securities represented by the Global Preferred Securities
may from time to time be increased or decreased by adjustments made on the
"Schedule of Increases or Decreases in Global Preferred Security" attached
thereto (or books and records of the Property Trustee and the Clearing Agency or
its nominee) as hereinafter provided.

     Except as provided in Sections 6.22(e) and 6.22(f), Preferred Security
Beneficial Owners shall not be entitled to receive physical delivery of
definitive, fully registered Preferred Securities Certificates ("Definitive
Preferred Securities").

SECTION 6.4 THE SPONSOR'S PURCHASE OF THE COMMON SECURITIES.

     (a) On the Closing Date or any Option Closing Date, the Sponsor shall
purchase all of the Common Securities issued by the Trust, in an aggregate
liquidation amount equal to at least 3% of the total capital of the Trust, at
such time as the Preferred Securities are sold and issued. The aggregate stated
liquidation amount of the Common Securities outstanding at any time shall not be
less than 3% of the total capital of the Trust.

     (b) For so long as the Preferred Securities remain outstanding, the Sponsor
shall covenant:

          (i) to maintain, directly or indirectly, 100% ownership of the Common
     Securities; provided, however, that any permitted successor of the Sponsor
     (in its capacity as Debenture Issuer) under the Indenture may succeed to
     the Sponsor's ownership of such Common Securities;

          (ii) to cause the Trust to (a) remain a statutory business trust,
     except in connection with the distribution of the Debentures to the
     Holders, the redemption of all of the Securities, or certain mergers,
     consolidations, conversions or amalgamations, each as permitted by this
     Trust Agreement, (b) to the fullest extent permitted by law, not to
     voluntarily dissolve, wind up, liquidate or be terminated, except as
     permitted by this Trust Agreement and (c) otherwise continue to be
     classified as a grantor trust for United States federal income tax
     purposes;

          (iii) to use its commercially reasonable efforts to ensure that the
     Trust will not be an Investment Company required to be registered under the
     Investment Company Act; and

          (iv) not to take any action that would be reasonably likely to cause
     the Trust to be classified as an association or a publicly traded
     partnership taxable as a corporation for United States federal income tax
     purposes.

                                       41
<PAGE>

SECTION 6.5 DISTRIBUTIONS.

     (a) Holders shall be entitled to receive Distributions that shall be
payable at a rate per annum of 6% (the "Coupon Rate") of the stated liquidation
amount of $50 per Security from and including November 14, 2001 to, but
excluding, the Remarketing Date, and at the Reset Rate of the Accreted Value of
the Security on the Remarketing Date to, but excluding, the date of redemption.
At all times, the Distribution rate shall correspond to the interest rate on the
Debentures. The amount of a Distribution payable shall be computed:

          (i) for any full 90-day quarterly Distribution period, on the basis of
     a 360-day year consisting of twelve 30-day months;

          (ii) for any period shorter than a full 90-day quarterly Distribution
     period, on the basis of a 30-day month; and

          (iii) for any period shorter than a 30-day month, on the basis of the
     actual number of days elapsed in the 30-day month.

Subject to Section 6.1(e), Distributions shall be made on the Securities on a
Pro Rata basis. Distributions shall be payable on the Distribution Dates only to
the extent that payments are made to the Trust in respect of the Debentures held
by the Property Trustee and to the extent the Trust has funds available for the
payment of such Distributions in the Property Account.

     (b) Distributions on the Securities shall accumulate from the date of
original issue, shall be cumulative and shall be payable quarterly in arrears on
February 1, May 1, August 1 and November 1 of each year (each, a "Distribution
Date"), commencing on February 1, 2002, when, as and if available for payment,
except as otherwise provided in this Trust Agreement. Interest not paid on the
Debentures on the scheduled Interest Payment Dates shall accrue and compound
quarterly at the Coupon Rate of the aggregate principal amount or the Reset Rate
of the Accreted Value on the Remarketing Date, as applicable, and, as a result,
Distributions not paid on the scheduled Distribution Dates shall accumulate and
compound quarterly at the Coupon Rate of the aggregate stated liquidation amount
or the Reset Rate of the Accreted Value on the Remarketing Date, as applicable
("Compounded Distributions"). The terms "Distribution" shall mean ordinary
quarterly distributions together with any Compounded Distributions.

     (c) As long as no Indenture Event of Default has occurred and is continuing
and as long as a Failed Remarketing has not occurred, the Debenture Issuer has
the right under the Indenture to defer payments of interest on the Debentures by
extending the interest payment period, at any time and from time to time, on the
Debentures for a period not exceeding 20 consecutive quarters (each, an
"Extension Period"), during which Extension Period no interest shall be due and
payable on the Debentures, provided that no Extension Period shall end on a date
other than an Interest Payment Date or extend beyond the stated maturity of the
Debentures. Upon the occurrence of a Failed Remarketing, any such Extension
Period shall terminate and interest shall be payable on the next Interest
Payment Date. As a consequence of such deferral, Distributions also shall be
deferred. Despite such deferral, interest on the Debentures shall continue to
accrue with additional interest thereon (to the extent permitted by applicable
law) and, as a result, Distributions shall continue to accumulate with
additional Distributions thereon

                                       42
<PAGE>

(to the extent permitted by applicable law) at the Coupon Rate of the stated
liquidation amount or at the Reset Rate of the Accreted Value on the Remarketing
Date, as the case may be, compounded quarterly during any such Extension Period.
Prior to the termination of any such Extension Period, the Debenture Issuer may
further defer payments of interest by further extending such Extension Period;
provided that such Extension Period, together with all such previous and further
extensions of such Extension Period, may not exceed 20 consecutive quarters or
extend beyond the stated maturity date of the Debentures. Upon the termination
of any Extension Period and the payment of all amounts then due, the Debenture
Issuer may commence a new Extension Period, subject to the above requirements.

     (d) Distributions on the Securities shall be payable to the Holders as they
appear on the books and records of the Trust at the close of business on the
relevant Regular Record Dates; provided that Distributions payable on the
Remarketing Settlement Date shall be payable to the Holders as they appear on
the books and records of the Trust at the close of business on the Special
Record Date. If the Preferred Securities are represented by one or more Global
Preferred Securities, the relevant Regular Record Dates shall be the close of
business on the Business Day preceding the corresponding Distribution Date,
unless a different Regular Record Date is established or provided for the
corresponding Interest Payment Date on the Debentures. If the Preferred
Securities are not represented by one or more Global Preferred Securities, the
relevant Regular Record Dates for the Preferred Securities shall be at least one
Business Day prior to the corresponding Distribution Dates, or such other dates
as may be selected by the Administrative Trustees. The record dates for the
Common Securities shall be the same as the record dates for the Preferred
Securities. At all times, the Distribution Dates shall correspond to the
Interest Payment Dates on the Debentures.

     Distributions payable on any Securities that are not punctually paid on any
Distribution 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 instead shall be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with the Indenture for payment of the corresponding
defaulted interest on the Debentures.

     (e) If any date on which a Distribution is payable on the Securities is not
a Business Day, payment of the Distribution payable on such date will be made on
the next day that is a Business Day (and without any additional Distribution or
other payment in respect of any such delay), except that if such Business Day is
in the next calendar year, such payment shall be made on the immediately
preceding Business Day with the same force and effect as if made on the date
such payment was originally payable.

     (f) If and to the extent that the Debenture Issuer makes a payment of
principal of and premium, if any, and interest 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 distribution of the Payment Amount to the Holders on a
Pro Rata basis, subject to Section 6.1(e).

                                       43
<PAGE>

     (g) 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 on a Pro Rata basis among the Holders subject to 6.1(e).

SECTION 6.6 REMARKETING.

     (a) In connection with a Remarketing of the Preferred Securities:

          (i) in connection with a Remarketing upon a Trading Remarketing Event
     or a Legal Cause Remarketing Event, the Accreted Value of the Debentures as
     of the end of the day on the day next preceding the Remarketing Date shall
     become due on the date which is 60 days following the Remarketing Date,
     and, as a result, the Accreted Value of the Securities as of the end of the
     day on the day next preceding the Remarketing Date shall be redeemed on the
     date which is 60 days following the Remarketing Date;

          (ii) on the Remarketing Date, the rate of interest per annum on the
     Accreted Value of the Debentures shall become the Reset Rate on the
     Accreted Value of the Securities established in the Remarketing of the
     Preferred Securities, and, as a result, the Distribution rate per annum on
     the Accreted Value of the Securities shall become the Reset Rate
     established in the Remarketing of the Preferred Securities;

          (iii) on the Remarketing Settlement Date, interest accrued and unpaid
     on the Debentures from and including the immediately preceding Interest
     Payment Date to, but excluding, the Remarketing Settlement Date shall be
     payable to the holders of the Debentures on the Special Record Date, and,
     as a result, Distributions accumulated and unpaid on the Securities from
     and including the immediately preceding Distribution Date to, but
     excluding, the Remarketing Settlement Date shall be payable to the Holders
     of the Securities on the Special Record Date;

          (iv) in connection with a Remarketing upon a Trading Remarketing Event
     or a Legal Cause Remarketing Event, the Sponsor shall be obligated to
     redeem the Warrants on the Remarketing Settlement Date at a redemption
     price per Warrant equal to the Warrant Value as of the end of the day on
     the day next preceding the Remarketing Date; and

          (v) on and after the Remarketing Date, the Warrants shall be
     exercisable at the Exercise Price.

     (b) The proceeds from the Remarketing of the Preferred Securities shall be
paid to the selling Holders, provided that, upon a Trading Remarketing Event or
a Legal Cause Remarketing Event, the proceeds from the Remarketing of the
Preferred Securities that are held pursuant to the Unit Agreement for which the
holders of such Units have elected to exercise their Warrants shall be paid
directly to the Warrant Agent to satisfy in full the Exercise Price of the
Warrants held by such holders.

     (c) In connection with a Remarketing of the Preferred Securities and at any
time thereafter, a purchaser may exchange its Preferred Securities for its pro
rata share of Debentures. In such event, the Administrative Trustees shall cause
Debentures held by the Property Trustee,

                                       44
<PAGE>

having an aggregate Accreted Value equal to the aggregate Accreted Value of the
Preferred Securities purchased by such purchaser and with accrued and unpaid
interest equal to the accumulated and unpaid Distributions on the Preferred
Securities purchased by such purchaser, to be distributed to such purchaser in
exchange for such Holders' pro rata interest in the Trust. In such event, the
Debentures held by the Trust shall decrease by the amount of Debentures
delivered to the purchaser of Preferred Securities.

     (d) Upon the occurrence of a Trading Remarketing Event, the Sponsor shall
cause a Remarketing of the Preferred Securities and select a Remarketing Date,
provided that the following conditions precedent are satisfied:

          (i) as of the date of which the Sponsor causes a Remarketing of the
     Preferred Securities, the Closing Price of a share of the Common Stock
     exceeds and has exceeded for at least 20 Trading Days within the
     immediately preceding 30 consecutive Trading Days, $37.57 per share.

          (ii) as of the date of which the Sponsor causes a Remarketing of the
     Preferred Securities and on the Remarketing Date, no Trust Enforcement
     Event or deferral of Distributions to Holders of the Preferred Securities
     shall have occurred and be continuing;

          (iii) as of the date of which the Sponsor causes a Remarketing of the
     Preferred Securities and on the Remarketing Date, a registration statement
     covering the issuance and sale of Common Stock to the holders of Warrants
     upon exercise of such Warrants shall be effective under the Securities Act,
     or the issuance and sale of Common Stock to the holders of Warrants upon
     exercise of such Warrants shall be exempt from registration requirements
     under the Securities Act; and

          (iv) on the Remarketing Date, the Legal Requirements shall have been
     satisfied.

The settlement of the Remarketing shall occur on the Remarketing Settlement
Date, provided that the following conditions precedent are satisfied on the
Remarketing Settlement Date:

               (A) the Warrant Requirements shall be satisfied; and

               (B) pursuant to the Warrant Agreement, a redemption of the
          Warrants of those holders who have not elected to exercise their
          Warrants prior to or on such date shall have been consummated.

If any of the foregoing conditions precedent are not satisfied, the Remarketing
of the Preferred Securities cannot occur and the contemporaneous redemption of
Warrants shall be canceled; provided, however, that if:

          (x) the Remarketing cannot occur because of a failure to satisfy

     relevant date or dates; and

          (y) the Sponsor is using its best efforts to satisfy such
     Requirements;

the Sponsor shall have the right to cause a Remarketing of the Preferred
Securities on a subsequent date which is no later than September 13, 2031,
provided that all applicable requirements and conditions precedents (including
the timely occurrence of a Trading Remarketing Event) are satisfied.

     (e) Upon the occurrence of a Legal Cause Remarketing Event, the Sponsor
shall cause a Remarketing of the Preferred Securities and select a Remarketing
Date, provided that the following conditions precedent are satisfied:

          (i) as of the date of which the Sponsor causes a Remarketing of the
     Preferred Securities and on the Remarketing Date, no Trust Enforcement
     Event shall have occurred and be continuing;

          (ii) as of the date of which the Sponsor causes a Remarketing of the
     Preferred Securities and on the Remarketing Date, a registration statement
     covering the issuance and sale of Common Stock to the holders of Warrants
     upon exercise of such Warrants shall be effective under the Securities Act,
     or the issuance and sale of Common Stock to the holders of Warrants upon
     exercise of such Warrants shall be exempt from registration requirements
     under the Securities Act; and

          (iii) on the Remarketing Date, the Legal Requirements shall have been
     satisfied.

The settlement of the Remarketing shall occur on the Remarketing Settlement
Date, provided that the following conditions precedent are satisfied on the
Remarketing Settlement Date:

               (A) the Warrant Requirements shall be satisfied; and

               (B) a redemption of the Warrants of those holders who have not
          elected to exercise their Warrants prior to or on such date shall have
          been consummated pursuant to the Warrant Agreement.

If any of the foregoing conditions precedent are not satisfied, the Remarketing
cannot occur and the contemporaneous redemption of Warrants shall be canceled;
provided, however, that if:

          (x) the Remarketing cannot occur because of a failure to satisfy
     either the Warrant Requirements or the Legal Requirements as of or on the
     relevant date or dates; and

          (y) the Sponsor is using its best efforts to satisfy such
     Requirements;

the Sponsor shall have the right to cause a Remarketing of the Preferred
Securities on a subsequent date which is no later than September 13, 2031,
provided that all applicable requirements and conditions precedents (including
the timely occurrence of a Legal Cause Remarketing Event) are satisfied.

                                       46

     (f) On the Maturity Remarketing Date, a Remarketing of the Preferred
Securities shall occur, provided that on such date, the Legal Requirements (to
the extent applicable) shall have been satisfied.

     If, for any reason, a Remarketing of the Preferred Securities does not
occur on the Maturity Remarketing Date, the Administrative Trustees shall give
notice thereof to all Holders of Preferred Securities (whether or not held
pursuant to the Unit Agreement) prior to the close of business on the following
Business Day. In such event:

          (i) the rate of interest per annum on the Accreted Value of the
     Debentures (which, on the Maturity Remarketing Date, shall be equal to the
     principal amount of the Debentures) shall become the Reset Rate, and, as a
     result, the rate of Distribution per annum on the Accreted Value of the
     Securities (which, on the Maturity Remarketing Date, shall be equal to the
     stated liquidation amount of the Securities) shall become the Reset Rate;
     and

          (ii) pursuant to the Indenture, the Debenture Issuer no longer shall
     have the option to defer payments of interest on the Debentures.

     (g) Upon the occurrence of a Trading Remarketing Event or a Legal Cause
Remarketing Event and the election by the Sponsor to cause a Remarketing of the
Preferred Securities, or upon the Maturity Remarketing Date, as long as the
Preferred Securities are evidenced by Global Preferred Securities, deposited
with the Clearing Agency, the Sponsor shall request, not later than four nor
more than 20 days prior to the Remarketing Date, that the Clearing Agency notify
the Holders of the Preferred Securities of the Remarketing of the Preferred
Securities and of the procedures that must be followed if such Holder of
Preferred Securities wishes to elect not to participate in the Remarketing of
the Preferred Securities.

     (h) Upon the occurrence of a Remarketing Event, all of the Preferred
Securities (excluding the Preferred Securities as to which the Holders thereof
have elected not to participate in the Remarketing) shall be remarketed by the
Remarketing Agent. Not later than 5:00 p.m. (New York City time) on the Business
Day preceding the Remarketing Date, each Holder of Preferred Securities may
elect not to have the Preferred Securities held by such Holder remarketed in the
Remarketing. Holders of Preferred Securities that are not held pursuant to the
Unit Agreement shall give such notice to the Property Trustee, and Holders of
Preferred Securities that are held pursuant to the Unit Agreement shall give
such notice to the Unit Agent. Holders of Preferred Securities that are not held
pursuant to the Unit Agreement and Holders of Preferred Securities that are held
pursuant to the Unit Agreement that do not give notice of their intention not to
participate in the Remarketing shall be deemed to have consented to the
disposition of their Preferred Securities in the Remarketing. Any such notice
shall be irrevocable and may not be conditioned upon the level at which the
Reset Rate is established in the Remarketing.

     Not later than 5:00 p.m. (New York City time) on the Business Day preceding
the Remarketing Date, the Property Trustee and the Unit Agent, as applicable,
based on the notices received by it prior to such time, shall notify the Trust,
the Sponsor and the Remarketing Agent of the number of Preferred Securities to
be tendered for purchase in the Remarketing.

                                       47
<PAGE>

     (i) The right of each Holder to have Preferred Securities tendered for
purchase shall be limited to the extent that:

          (i) the Remarketing Agent conducts a Remarketing pursuant to the terms
     of the Remarketing Agreement;

          (ii) the Remarketing Agent is able to find a purchaser or purchasers
     for the Preferred Securities deemed tendered; and

          (iii) such purchaser or purchasers deliver the purchase price therefor
     to the Remarketing Agent.

     (j) On the Remarketing Date, the Remarketing Agent shall use commercially
reasonable efforts to remarket the Preferred Securities deemed tendered for
purchase at a price equal to:

          (i) in connection with a Remarketing upon a Trading Remarketing Event
     or a Legal Cause Remarketing Event, 100% of the aggregate Accreted Value as
     of the end of the day on the day next preceding the Remarketing Date; and

          (ii) on the Maturity Remarketing Date, 100% of the stated liquidation
     amount.

     (k) If, as a result of the efforts described in 6.6(j), the Remarketing
Agent determines that it will be able to remarket all of the Preferred
Securities deemed tendered for purchase at the purchase price set forth in
Section 6.6(j) prior to 4:00 p.m. (New York City time) on the Remarketing Date,
the Remarketing Agent shall determine the Reset Rate, which shall be the rate
per annum (rounded to the nearest one-thousandth (0.001) of 1% per annum) that
the Remarketing Agent determines, in its sole judgment, to be the lowest rate
per annum that will enable it to remarket all of the Preferred Securities deemed
tendered for Remarketing.

     (l) If none of the Holders of the Preferred Securities or the holders of
the Units elects to have their Preferred Securities remarketed in the
Remarketing, the Reset Rate shall equal the rate determined by the Remarketing
Agent, in its sole discretion, as the rate that would have been established had
a Remarketing been held on the Remarketing Date, and the related modifications
to the other terms of the Preferred Securities and to the terms of the
Debentures and the Warrants shall be effective as of the Remarketing Date.

     (m) If, by 4:00 p.m. (New York City time) on the Remarketing Date, the
Remarketing Agent is unable to remarket all of the Preferred Securities deemed
tendered for purchase, a "Failed Remarketing" shall be deemed to have occurred
and the Remarketing Agent shall so advise by telephone the Clearing Agency, the
Property Trustee, the Debenture Trustee, the Administrative Trustees on behalf
of the Trust and the Sponsor. The Administrative Trustees shall then give notice
of the Failed Remarketing to the Holders of the Preferred Securities prior to
the close of business on the Business Day following the Failed Remarketing Date.
In the event of a Failed Remarketing:

          (i) the Accreted Value of the Debentures as of the end of the day on
     the day next preceding the Remarketing Date shall become due on the date
     which is 60 days

                                       48
<PAGE>

     following the Failed Remarketing Date, and, as a result, the Accreted Value
     of the Securities as of the end of the day on the day next preceding the
     Remarketing Date shall be redeemed on the date which is 60 days following
     the Failed Remarketing Date;

          (ii) the rate of interest per annum on the Accreted Value of the
     Debentures shall become the Reset Rate, and, as a result, the rate of
     Distribution per annum on the Accreted Value of the Securities shall become
     the Reset Rate; and

          (iii) pursuant to the Indenture, the Debenture Issuer no longer shall
     have the option to defer payments of interest on the Debentures.
     Notwithstanding a Failed Remarketing, subject to the satisfaction of the
     Legal Requirements, the Warrants shall be redeemed at the Warrant Value and
     a holder of Warrants shall have the option to exercise its Warrants in lieu
     of such redemption, as provided in the Unit Agreement and the Warrant
     Agreement.

     (n) By approximately 4:30 p.m. (New York City time) on the Remarketing
Date, provided that there has not been a Failed Remarketing, the Remarketing
Agent shall advise, by telephone:

          (i) the Clearing Agency, the Property Trustee, the Debenture Trustee,
     the Trust and the Sponsor of the Reset Rate determined in the Remarketing
     and the number of Preferred Securities sold in the Remarketing;

          (ii) each purchaser (or the Clearing Agency Participant thereof) of
     the Reset Rate and the number of Preferred Securities such purchaser is to
     purchase; and

          (iii) each purchaser to give instructions to its Clearing Agency
     Participant to pay the purchase price on the Remarketing Settlement Date in
     same day funds against delivery of the Preferred Securities purchased
     through the facilities of the Clearing Agency.

     (o) In accordance with the Clearing Agency's normal procedures, on the
Remarketing Settlement Date, the transactions described above with respect to
each Preferred Security deemed tendered for purchase and sold in the Remarketing
shall be executed through the Clearing Agency, and the accounts of the
respective Clearing Agency Participants shall be debited and credited and such
Preferred Securities delivered by book-entry as necessary to effect purchases
and sales of such Preferred Securities. The Clearing Agency shall make payment
in accordance with its normal procedures.

     (p) If any Holder of the Preferred Securities selling such Preferred
Securities (or any holder of Units selling the Preferred Securities that are
held pursuant to the Unit Agreement) in the Remarketing fails to deliver such
Preferred Securities, the Clearing Agency Participant of such selling holder and
of any other Person that was to have purchased Preferred Securities in the
Remarketing may deliver to any such other Person a number of Preferred
Securities that is less than the number of Preferred Securities that otherwise
was to be purchased by such Person. In such event, the number of Preferred
Securities to be so delivered shall be determined by such Clearing Agency
Participant, and delivery of such lesser number of Preferred Securities shall
constitute good delivery.

                                       49
<PAGE>

     (q) The Remarketing Agent is not obligated to purchase any Preferred
Securities that otherwise would remain unsold in the Remarketing. Neither the
Trust, any Trustee, the Sponsor nor the Remarketing Agent shall be obligated in
any case to provide funds to make payment upon tender of the Preferred
Securities for Remarketing.

     (r) Under the Remarketing Agreement, the Sponsor, in its capacity as
Debenture Issuer, shall be liable for, and shall pay, any and all costs and
expenses incurred in connection with the Remarketing, and the Trust shall not
have any liabilities for such costs and expenses.

     (s) The tender and settlement procedures set in this Section 6.6, including
provisions for payment by purchasers of the Preferred Securities in the
Remarketing, shall be subject to modification to the extent required by the
Clearing Agency or if the book-entry system is no longer available for the
Preferred Securities at the time of the Remarketing, to facilitate the tendering
and remarketing of the Preferred Securities in definitive form. In addition, the
Remarketing Agent may modify the settlement procedures set forth herein in order
to facilitate the settlement process.

SECTION 6.7 LIMITED RIGHT TO REQUIRE EXCHANGE OF PREFERRED SECURITIES AND
            REPURCHASE OF DEBENTURES.

     (a) Upon the exercise of Warrants by a holder of Units on a date other than
a Remarketing Settlement Date, such Holder shall have the right (the "Repurchase

following the exercise date of such Warrants, to require the Trust to exchange

     the beneficial owner of the Preferred Securities to be exchanged.

     (c) No less than three Business Days prior to the applicable Required

          (i) if the Preferred Securities to be exchanged are represented by a
     Global Preferred Security, the Property Trustee shall make, in accordance

     (a) Upon the occurrence of a Change of Control, each Holder of a Preferred
Security shall have the right (a "Change of Control Repurchase Right") to

SECTION 6.9 REDEMPTION.

     (a) Except as provided in Sections 6.7 and 6.8, upon the repayment of the
Debentures held by the Trust, in whole or in part, whether at Stated Maturity
(as adjusted in connection with a Remarketing, if applicable) or otherwise, the
proceeds from such repayment shall be simultaneously applied by the Property
Trustee (subject to the Property Trustee having received notice no later than 45
days prior to such repayment) to redeem a Like Amount of the Securities at a
redemption price equal to the redemption price in respect of the Debentures plus
an amount equal to accumulated and unpaid Distributions on the Securities
through the date of redemption (the "Redemption Price"). The Redemption Price
shall be payable on the date of redemption (the "Redemption Date") only to the
extent that the Trust has sufficient funds available for the payment of such
Redemption Price.

     (b) If the Debentures are repaid in part, the Securities shall be redeemed
in part. Except as provided in Section 6.13, the proceeds from such repayment of
Debentures shall be allocated on a Pro Rata basis to the redemption of the
Securities.

     (c) The procedure with respect to redemptions of Securities shall be as
follows:

          (i) Notice of any redemption of Securities (a "Redemption Notice"),
     which notice shall be irrevocable, shall be given by the Trust by mail to
     each Holder of Securities to be redeemed not fewer than 30 nor more than 60
     days before the Redemption Date, which shall be the date fixed for
     repayment of the Debentures. A Redemption Notice shall be deemed to be
     given on the day such notice is first mailed by first-class mail, postage
     prepaid, to Holders. No defect in the Redemption Notice or in the mailing
     of the Redemption Notice with respect to any Holder shall affect the
     validity of the redemption proceedings with respect to any other Holder.

                                       52
<PAGE>

          (ii) Each Redemption Notice shall be sent by the Property Trustee on
     behalf of the Trust to:

               (A) in respect of the Preferred Securities, the Clearing Agency
          or its nominee (or any successor Clearing Agency or its nominee) if
          the Global Preferred Securities have been issued or, the Holders
          thereof if Definitive Preferred Securities have been issued, and

               (B) in respect of the Common Securities, the Holder (or Holders)
          thereof.

          (iii) Once the Trust gives a Redemption Notice:

               (A) with respect to Preferred Securities issued in book-entry
          form, by 12:00 noon (New York City time) on the Redemption Date of
          such Preferred Securities, provided that the Debenture Issuer has paid
          the Property Trustee a sufficient amount of cash in connection with
          the related repayment of the Debentures by 10:00 a.m. (New York City
          time) on the maturity date, the Property Trustee shall deposit
          irrevocably with the Clearing Agency or its nominee (or successor
          Clearing Agency or its nominee) funds sufficient to pay the applicable
          Redemption Price with respect to such Global Preferred Securities and
          shall give the Clearing Agency irrevocable instructions and authority
          to pay the Redemption Price to the relevant Clearing Agency
          Participants, and

               (B) with respect to Preferred Securities issued in definitive
          form and Common Securities, by 12:00 noon (New York City time) on the
          Redemption Date of such Securities, provided that the Debenture Issuer
          has paid the Property Trustee a sufficient amount of cash in
          connection with the related repayment of the Debentures by 10:00 a.m.
          (New York City time) on the maturity date, the Property Trustee shall
          deposit irrevocably with the Paying Agent funds sufficient to pay the
          applicable Redemption Price with respect to such Definitive Preferred
          Securities and Common Securities and shall give the Paying Agent
          irrevocable instructions and authority to pay the Redemption Price to
          the relevant Holders upon surrender of their Certificates evidencing
          their Securities.

          (iv) If a Redemption Notice shall have been given and funds deposited
     as required, then, immediately prior to the close of business on the
     Redemption Date, Distributions shall cease to accumulate on the Securities
     called for redemption and all rights of Holders of Securities called for
     redemption, except the right of such Holders to receive the Redemption
     Price (but without interest on such Redemption Price), shall cease, and
     such Securities shall cease to be outstanding.

          (v) Payment of accumulated and unpaid Distributions on the Redemption
     Date of the Securities shall be subject to the rights of Holders on the
     close of business on a Regular Record Date in respect of a Distribution
     Date occurring prior to or on such Redemption Date.

                                       53
<PAGE>

          (vi) If any Redemption Date is not a Business Day, payment of the
     Redemption Price payable on such Redemption Date shall be made on the next
     day that is a Business Day (and without any interest or other payment in
     respect of any such delay) except that, if such next Business Day falls in
     the next calendar year, such payment shall be made on the immediately
     preceding Business Day, in each case with the same force and effect as if
     made on the date such payment was originally payable.

          (vii) If payment of the Redemption Price in respect of any Securities
     called for redemption is improperly withheld or refused and not paid either
     by the Property Trustee or by the Sponsor pursuant to the Guarantee,
     Distributions on such Securities shall continue to accumulate from the
     redemption date originally established by the Trust to the date such
     Redemption Price is actually paid, in which case the actual payment date
     shall be the Redemption Date for purposes of calculating the Redemption
     Price.

          (viii) Subject to the foregoing and applicable law (including, without
     limitation, United States federal securities laws and banking laws), the
     Sponsor or any of 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 6.10 DISTRIBUTION OF DEBENTURES IN EXCHANGE FOR SECURITIES UPON THE
             OCCURRENCE OF A SPECIAL EVENT.

     (a) If at any time either a Tax Event or an Investment Company Act Event
occurs (each, a "Special Event") and certain conditions set forth in Section
6.10(b) are satisfied, the Administrative Trustees may dissolve the Trust and,
after satisfaction of liabilities to creditors of the Trust as provided by
applicable law, cause the Debentures held by the Property Trustee to be
distributed to the Holders in liquidation of such Holders' interests in the
Trust on a Pro Rata basis, upon not less than 30 nor more than 60 days notice,
within the 90 days following the occurrence of such Special Event (the "90 Day
Period"), and, simultaneous with such distribution, to cause a Like Amount of
the Securities to be exchanged by the Trust on a Pro Rata basis.

     (b) The dissolution of the Trust and distribution of the Debentures
pursuant to Section 6.10(a) shall be permitted only upon satisfaction of the
following three conditions:

          (i) the receipt by the Administrative Trustees of an Opinion of
     Counsel, rendered by an independent law firm having a recognized national
     tax practice, to the effect that the Holder shall not recognize any gain or
     loss for United States federal income tax purposes as a result of the
     dissolution of the Trust and the distribution of the Debentures (a "No
     Recognition Opinion"); provided that if a Special Event occurs and the
     Administrative Trustees are informed by an independent counsel that such
     counsel cannot deliver a No Recognition Opinion to the Trust, and thus a
     dissolution of the Trust and distribution of the Debentures shall not be
     permitted, the Debenture Issuer shall have the right to cause a Remarketing
     of the Preferred Securities as set forth in Section 6.6 within the 90 Day
     Period;

                                       54
<PAGE>

          (ii) neither the Trust nor the Debenture Issuer being able to
     eliminate, which elimination shall be complete within the 90 Day Period,
     such Special Event by taking some ministerial action (such as filing a
     form, making an election or pursuing some other reasonable measure) that:

               (A) has no material adverse effect on the Trust, the Debenture
          Issuer or the Holders; or

               (B) does not subject any of them to more than de minimis
          regulatory requirements; and

          (iii) the receipt by the Administrative Trustees of the prior written
     consent of the Debenture Issuer.

     (c) Notice of any distribution of Debentures in exchange for the Securities
(a "Debenture Distribution Notice"), which notice shall be irrevocable, shall be
given by the Trust by mail to each Holder of Securities not fewer than 30 nor
more than 60 days before the date of distribution of the Debentures. A Debenture
Distribution Notice shall be deemed to be given on the day such notice is first
mailed by first-class mail, postage prepaid, to Holders. No defect in the
Debenture Distribution Notice or in the mailing of the Debenture Distribution
Notice with respect to any Holder shall affect the validity of the exchange
proceedings with respect to any other Holder.

     Each Debenture Distribution Notice shall be sent by the Property Trustee on
behalf of the Trust to:

          (i) in respect of the Preferred Securities, the Clearing Agency or its
     nominee (or any successor Clearing Agency or its nominee) if the Global
     Preferred Securities have been issued or, the Holders thereof if Definitive
     Preferred Securities have been issued, and

          (ii) in respect of the Common Securities, the Holder (or Holders)
     thereof.

     (d) On and from the date fixed by the Property Trustee for any distribution
of Debentures and liquidation of the Trust:

          (i) the Securities no longer shall be deemed to be outstanding;

          (ii) the Clearing Agency or its nominee (or any successor Clearing
     Agency or its nominee), as the Holder of the Preferred Securities, will
     receive a registered global certificate or certificates representing the
     Debentures to be delivered upon such distribution; and

          (iii) any certificates representing Securities not held by the
     Clearing Agency or its nominee (or any successor Clearing Agency or its
     nominee) shall be deemed to represent Debentures having an aggregate
     principal amount equal to the aggregate liquidation amount of such
     Securities and bearing accrued and unpaid interest in an amount equal to
     the accumulated and unpaid Distributions on such Securities, until such

                                       55
<PAGE>

     certificates are presented for cancellation, at which time the Debenture
     Issuer shall issue, and the Debenture Trustee shall authenticate, a
     certificate representing such Debentures.

     (e) In the event of a dissolution of the Trust and a distribution of the
Debentures, pursuant to the Indenture, the Debenture Issuer shall have the same
rights, and shall be subject to the same terms and conditions, to cause a
Remarketing of the Debentures as the Sponsor has and is subject to under Section
6.6 to cause a Remarketing of the Preferred Securities.

SECTION 6.11 VOTING RIGHTS OF THE PREFERRED SECURITIES.

     (a) Except as provided under this Section 6.11 and 11.1 and as otherwise
required by the Delaware Business Trust Act, this Trust Agreement and other
applicable law, the Holders of the Preferred Securities shall have no voting
rights.

     (b) Subject to the requirement of the Property Trustee obtaining a tax
opinion in certain circumstances set forth in Section 6.11(d), the Holders of a
Majority in Liquidation Amount of the Preferred Securities, voting separately as
a class, shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Property Trustee, or to direct
the exercise of any trust or power conferred upon the Property Trustee under
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;

          (ii) consent to any amendment or modification of the Indenture or the
     Debentures where such consent is required; or

          (iii) waive any past default and its consequences that are waivable
     under Section 2.11 of the Indenture;

provided that if an Indenture Event of Default has occurred and is continuing,
the Holders of at least 25% of the aggregate stated liquidation amount of the
Preferred Securities may direct the Property Trustee to declare the principal of
and premium, if any, and interest on the Debentures due and payable; and
provided further that where a consent or action under the Indenture would
require the consent or act of the Holders of a Super Majority of the aggregate
principal amount of Debentures affected thereby, the Property Trustee may give
such consent or take such action only at the written direction of the Holders of
at least the proportion in aggregate liquidation amount of the Preferred
Securities that the relevant Super Majority represents of the aggregate
principal amount of the Debentures outstanding.

     (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 institute, to the fullest extent
permitted by law, 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

                                       56
<PAGE>

due under the Indenture, then a Holder of Preferred Securities may institute a
Direct Action against the Debenture Issuer on or after the respective due date
specified in the Debentures.

     (d) The Property Trustee shall notify all Holders of the Preferred
Securities of any notice of any Indenture Event of Default received from the
Debenture Issuer with respect to the Debentures. Such notice shall state that
such Indenture Event of Default also constitutes a Trust Enforcement Event.
Except with respect to directing the time, method and place of conducting a
proceeding for a remedy, the Property Trustee shall be under no obligation to
take any of the actions described in clauses (i) and (ii) of Section 6.10(b),
unless the Property Trustee has obtained an Opinion of Counsel, rendered by an
independent law firm experienced in such matters, 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 that each Holder of
Preferred Securities shall be treated as owning an undivided beneficial interest
in the Debentures.

     (e) If 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 with respect to such amendment or modification and shall vote
with respect to such amendment or modification as directed by a Majority in
Liquidation Amount of the Securities voting together as a single class; provided
that where a consent under the Indenture would require the consent of the
Holders of a Super Majority of the aggregate principal amount of the Debentures,
the Property Trustee may give such consent only at the direction of the Holders
of at least the proportion in aggregate liquidation amount of the Securities
that the relevant Super Majority represents of the aggregate principal amount of
the Debentures outstanding. 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 Counsel, rendered by an independent
law firm experienced in such matters, 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 that each Holder of Securities will be
treated as owning an undivided beneficial interest in the Debentures.

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

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

                                       57
<PAGE>

     (h) No vote or consent of the Holders of the Preferred Securities shall be
required for the Trust to redeem and cancel the Preferred Securities or
distribute the Debentures in accordance with this Trust Agreement and the terms
of the Securities.

     (i) Notwithstanding that the Holders of the Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned at such time by the Sponsor, the
Trustees or any Affiliate of the Sponsor or any Trustee shall not be entitled to
vote or consent and shall be treated, for purposes of such vote or consent, as
if such Preferred Securities were not outstanding.

     (j) Except as provided under Section 6.11(k), the 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 Holders of the Common Securities.

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

SECTION 6.12 VOTING RIGHTS OF THE COMMON SECURITIES.

     (a) Except as provided in Section 5.1(b), this Section 6.12 and Section
11.1 and as otherwise required by the Delaware Business Trust Act, the Trust
Indenture Act or other applicable law, the Holders of the Common Securities
shall have no voting rights.

     (b) Subject to Section 6.11(k), the Holders of the Common Securities shall
be entitled to vote to appoint, remove or replace any Trustee or to increase or
decrease the number of Trustees in accordance with Article V.

     (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 obtaining an
Opinion of Counsel, rendered by an independent law firm experienced in such
matters, in certain circumstances set forth in this Section 6.12(c), the Holders
of the Common 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 to direct the exercise of any trust or power conferred upon the
Property Trustee under this Trust Agreement, including the right to direct the
Property Trustee, as the holder of the Debentures, to:

          (i) exercise the remedies available to it under the Indenture;

          (ii) consent to any amendment or modification of the Indenture or the
     Debentures where such consent is required; or

          (iii) waive any past default and its consequences that are waivable
     under Section 2.11 of the Indenture;

provided that where a consent or action under the Indenture would require the
consent or act of the Holders of a Super Majority of the aggregate principal
amount of Debentures affected

                                       58
<PAGE>

thereby, only the Holders of at least the proportion in aggregate liquidation
amount of the Common Securities that the relevant Super Majority represents of
the aggregate principal amount of the Debentures may direct the Property Trustee
to give such consent or take such action. Except with respect to directing the
time, method and place of conducting a proceeding for a remedy, the Property
Trustee shall be under no obligation to take any of the actions described in
clauses (i) and (ii) of this Section 6.11(c) unless the Property Trustee has
obtained an Opinion of Counsel, rendered by an independent law firm experienced
in such matters, 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
interest in the Debentures.

     (d) If the Property Trustee fails to enforce its rights under the
Debentures after the Holders of the Common Securities have made a written
request pursuant to Section 6.11(c), the Holders of the Common Securities may
institute, to the fullest extent permitted by law, 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 shall constitute a waiver of the corresponding Trust Enforcement
Event.

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

          (iii) instructions for the delivery of proxies.

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

SECTION 6.13 RANKING.

     The Preferred Securities rank pari passu with the Common Securities and
payment thereon shall be made on a Pro Rata basis with the Common Securities,
except that, if a Trust Enforcement Event occurs and is continuing, no payments
in respect of Distributions on, or payments upon liquidation, redemption or
otherwise with respect to, the Common Securities shall be made until the Holders
of the Preferred Securities shall be paid in full the Distributions, Redemption
Price, Liquidation Distribution and other payments to which they are entitled at
such time.

SECTION 6.14 REGISTRAR, PAYING AGENT AND TRANSFER AGENT.

     The Trust shall maintain in the Borough of Manhattan, The City of New York
or such other place as the Sponsor may designate:

          (i) an office or agency where Preferred Securities may be presented
     for registration of transfer ("Registrar"),

          (ii) an office or agency where Definitive Preferred Securities may be
     presented for payment, if any Preferred Securities are not represented by
     one or more Global Preferred Securities ("Paying Agent"); and

          (iii) an office or agency where Securities may be presented for
     transfer and exchange ("Transfer Agent").

     The Registrar shall keep a register of the Preferred Securities and of
their transfer. The term "Registrar" includes any additional registrar, "Paying
Agent" includes any additional paying agent and the term "Transfer Agent"
includes any additional transfer agent. The Administrative Trustees on behalf of
the Trust may appoint the Registrar, the Paying Agent and the Transfer Agent. If
the Administrative Trustees fail to appoint or maintain another entity as
Registrar, Paying Agent or Transfer Agent, the Property Trustee shall act as
such. The Trust or any of its Affiliates may act as Paying Agent, Registrar, or
Transfer Agent. The Administrative Trustees on behalf of the Trust may change
any Registrar, Paying Agent or Transfer Agent without prior notice to any
Holder. The Paying Agent shall be permitted to resign as Paying Agent upon 30
days' written notice to the Administrative Trustees. The Administrative Trustees
on behalf of the Trust shall notify the Property Trustee and the Holders of any
change in the location of the office or agency of any Agent.

     The Trust shall act as Registrar and Transfer Agent, and initially appoints
The Bank of New York as Paying Agent, for the Common Securities.

     The Trust initially appoints The Bank of New York as Registrar, Paying
Agent and Transfer Agent for the Preferred Securities.

SECTION 6.15 PAYING AGENT TO HOLD MONEY IN TRUST.

     The Trust shall require each Paying Agent other than the Property Trustee
to agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Property Trustee all money held by the Paying Agent for the
payment of Distributions, Redemption Price or Liquidation Amounts, and will
notify the Property Trustee if there are insufficient funds for such purpose.
While any such insufficiency continues, the Property Trustee may require a
Paying Agent to pay all money held by it to the Property Trustee. The Trust at
any time may require a Paying Agent to pay all money held by it to the Property
Trustee and to account for any money disbursed by it. Upon payment over to the
Property Trustee, the Paying Agent (if other than the Trust or an Affiliate of
the Trust) shall have no further liability for the money. If the Trust or the
Sponsor or any Affiliate of the Trust or the Sponsor acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent.

                                       60

SECTION 6.16 REPLACEMENT SECURITIES.

     If a Holder claims that a Security owned by it has been lost, destroyed or
wrongfully taken or if such Security is mutilated and is surrendered to the
Trust or in the case of the Preferred Securities to the Property Trustee, the
Trust shall issue and the Property Trustee shall, upon written order of the
Trust, authenticate a replacement Security if the Property Trustee's and the
Trust's requirements, as the case may be, are met. An indemnity bond must be
provided by the Holder which, in the judgment of the Property Trustee, is
sufficient to protect the Trustees, the Sponsor, the Trust or any Authenticating
Agent from any loss which any of them may suffer if a Security is replaced. The
Trust may charge such Holder for its expenses in replacing a Security.

SECTION 6.17 OUTSTANDING PREFERRED SECURITIES.

     The Preferred Securities outstanding at any time are all the Preferred
Securities authenticated by the Property Trustee and, in the case of the Global
Preferred Securities, specified in the "Schedule of Increases or Decreases in
Global Preferred Security" attached thereto (or on the books and records of the
Property Trustee and the Clearing Agency or its nominee), except for those
canceled by it, those delivered to it for cancellation, and those described in
this Section as not outstanding.

     A Preferred Security does not cease to be outstanding because the Sponsor,
one of the Trustees or any Affiliate of the Sponsor or any of the Trustees owns
the Security.

SECTION 6.18 PREFERRED SECURITIES IN TREASURY.

     In determining whether the Holders of the required amount of Securities
have concurred in any direction, waiver or consent, Preferred Securities owned
by the Sponsor, the Trustees or any Affiliate of the Sponsor or any Trustees, as
the case may be, shall be disregarded and deemed not to be outstanding, except
that for the purposes of determining whether the Property Trustee shall be fully
protected in relying on any such direction, waiver or consent, only Securities
which a Responsible Officer of the Property Trustee actually knows are so owned
shall be so disregarded.

SECTION 6.19 DEEMED SECURITY HOLDERS.

     The Trustees may treat the Person in whose name any Security shall be
registered on the books and records of the Trust as the sole owner of such
Security for purposes of receiving Distributions and for all other purposes
whatsoever. Accordingly, the Trustees shall not be bound to recognize any
equitable or other claim to or interest in such Security on the part of any
Person, whether or not the Trust shall have actual or other notice thereof.

SECTION 6.20 CANCELLATION.

The Trust at any time may deliver Preferred Securities to the Property Trustee
for cancellation. The Registrar, Paying Agent and Transfer Agent shall forward
to the Property Trustee any Preferred Securities surrendered to them for
registration of transfer, redemption, exchange or payment. The Property Trustee
shall promptly cancel all Preferred Securities

                                       61
<PAGE>

surrendered for registration of transfer, redemption, exchange, payment,
replacement or cancellation and shall dispose of cancelled Preferred Securities
as the Trust directs in writing, provided that the Property Trustee shall not be
obligated to destroy Preferred Securities. The Trust may not issue new Preferred
Securities to replace Preferred Securities that it has paid or that have been
delivered to the Property Trustee for cancellation or that any Holder has
exchanged.

SECTION 6.21 CUSIP NUMBERS.

     The Trust in issuing the Preferred Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Property Trustee shall use "CUSIP"
numbers in Redemption Notices, Distribution Notices and notices of Remarketing
or as a convenience to Holders of Preferred Securities; provided that any such
notice may state that no representation is made as to the correctness of such
numbers either as printed on the Preferred Securities or as contained in any
notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Preferred Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Sponsor will promptly notify the Property Trustee of any change in the CUSIP
numbers.

SECTION 6.22 GLOBAL PREFERRED SECURITIES; LEGENDS

     (a) Preferred Securities shall be issued initially in the form of one or
more permanent global notes in registered form without interest coupons, in
substantially the form set forth in Exhibit A (a "Global Preferred Security"),
deposited with the Paying Agent, as custodian for the Clearing Agency, and
registered in the name of the Clearing Agency or a nominee of the Clearing
Agency, duly executed by each Issuer and authenticated by the Property Trustee
as hereinafter provided.

     (b) Every Global Preferred Security authenticated, executed on behalf of
the Holders and delivered hereunder shall bear a legend in substantially the
following form:

     "THIS CERTIFICATE IS A GLOBAL CERTIFICATE WITHIN THE MEANING OF THE UNIT
     AGREEMENT HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE
     DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (THE "DEPOSITARY"), OR A
     NOMINEE OF THE DEPOSITARY. THIS CERTIFICATE IS EXCHANGEABLE FOR
     CERTIFICATES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY
     OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE UNIT
     AGREEMENT AND NO TRANSFER OF THIS CERTIFICATE (OTHER THAN A TRANSFER OF
     THIS CERTIFICATE AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE
     DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER
     NOMINEE OF THE DEPOSITARY) MAY BE REGISTERED EXCEPT IN LIMITED
     CIRCUMSTANCES.

                                       62
<PAGE>

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
     DEPOSITARY FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY
     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 SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
     HEREIN.

     (c) An Administrative Trustee shall execute, and the Property Trustee shall
authenticate and deliver, one or more Global Preferred Securities that:

          (i) shall be registered in the name of the Clearing Agency or the
     nominee of such Clearing Agency; and

          (ii) shall be delivered by the Property Trustee to such Clearing
     Agency or pursuant to such Clearing Agency's instructions.

The Global Preferred Securities shall represent such of the outstanding
Preferred Securities as shall be specified in the "Schedule of Increases or
Decreases in Global Preferred Security" attached thereto (or on the books and
records of the Property Trustee and the Clearing Agency or its nominee). The
Global Preferred Securities shall initially represent no Preferred Securities
and shall not, at any time, represent more than 3,500,000 (or 4,000,000 if the
Managing Underwriter's over-allotment option with respect to the Units is
exercised in full) Preferred Securities with a maximum liquidation value of
$175,000,000 (or $200,000,000 if the Managing Underwriter's over-allotment
option with respect to the Units is exercised in full).

     In addition, Global Preferred Securities shall bear a legend substantially
to the following effect:

     "This Preferred Security is a Global Preferred Security within the meaning
     of the Trust Agreement hereinafter referred to and is registered in the
     name of The Depository Trust Company, a New York corporation (the "Clearing
     Agency"), or a nominee of the Clearing Agency. This Preferred Security is
     exchangeable for Preferred Securities registered in the name of a person
     other than the Clearing Agency or its nominee only in the limited
     circumstances described in the Trust Agreement, and no transfer of this
     Preferred Security (other than a transfer of this Preferred Security as a
     whole by the Clearing Agency to a nominee of the Clearing Agency or by a
     nominee of the Clearing Agency to the Clearing Agency or another nominee of
     the Clearing Agency) may be registered except in limited circumstances.
     Unless this certificate is presented by an authorized representative of the
     Clearing Agency to IndyMac Capital Trust I or its agent for registration of
     transfer, exchange or payment, and any certificate issued is registered in
     the name

                                       63
<PAGE>

     of Cede & Co. or such other name as requested by an authorized
     representative of the Clearing Agency (and any payment hereon is made to
     Cede & Co. or to such other entity as is requested by an authorized
     representative of the Clearing Agency), and except as otherwise provided in
     the Trust Agreement, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
     OTHERWISE BY OR TO ANY PERSON IS WRONGFUL since the registered owner
     hereof, Cede & Co., has an interest herein."

     (d) Preferred Securities not represented by a Global Preferred Security
issued in exchange for all or a part of a Global Preferred Security pursuant to
this Section 6.22 shall be registered in such names and in such authorized
denominations as the Clearing Agency, pursuant to instructions from its direct
or indirect participants or otherwise, shall instruct the Property Trustee. Upon
execution and authentication, the Property Trustee shall deliver any Preferred
Securities not represented by a Global Preferred Security to the Persons in
whose names such Definitive Preferred Securities are so registered.

     (e) At such time as all interests in Global Preferred Securities have been
redeemed, repurchased or canceled, such Global Preferred Securities shall be
canceled, upon receipt thereof, by the Property Trustee in accordance with
standing procedures of the Clearing Agency. At any time prior to such
cancellation, if any interest in a Global Preferred Security is exchanged for
Preferred Securities not represented by a Global Preferred Security, redeemed,
canceled or transferred to a transferee who receives Preferred Securities not
represented by a Global Preferred Security, or if any Preferred Security not
represented by a Global Preferred Security is exchanged or transferred for part
of a Global Preferred Security, then, in accordance with the standing procedures
of the Clearing Agency, the aggregate stated liquidation amount of such Global
Preferred Security shall be reduced or increased, as the case may be, and an
endorsement shall be made on such Global Preferred Security by the Property
Trustee to reflect such reduction or increase in the "Schedule of Increases or
Decreases in Global Preferred Security" attached thereto.

     (f) The Trust and the Property Trustee, as the authorized representative of
the Holders of the Preferred Securities, may deal with the Clearing Agency for
all purposes of this Trust Agreement, including the making of payments due on
the Preferred Securities and exercising the rights of Holders of the Preferred
Securities hereunder. The rights of any Preferred Security Beneficial Owners
shall be limited to those established by law and agreements between such owners
and Clearing Agency Participants; provided that no such agreement shall give to
any Person any rights against the Trust or the Property Trustee without the
written consent of the parties so affected. Multiple requests and directions
from and votes of the Clearing Agency as the Holder of the Preferred Securities
represented by Global Preferred Securities with respect to any particular matter
shall not be deemed inconsistent to the extent they do not represent an amount
of Preferred Securities in excess of those held in the name of the Clearing
Agency or its nominee.

     (g) If at any time the Clearing Agency notifies the Trust that it is
unwilling or unable to continue as Clearing Agency for the Preferred Securities
or if at any time the Clearing Agency no longer is eligible to serve as Clearing
Agency, the Administrative Trustees shall appoint a successor Clearing Agency
with respect to the Preferred Securities. If a successor Clearing

                                       64
<PAGE>

Agency is not appointed by the Trust within 90 days after the Trust receives
such notice or becomes aware of such ineligibility, the Trust's election that
the Preferred Securities be represented by one or more Global Preferred
Securities shall no longer be effective, and an Administrative Trustee shall
execute, and the Property Trustee shall authenticate and deliver, Definitive
Preferred Securities, in any authorized denominations, in an aggregate stated
liquidation amount equal to the aggregate stated liquidation amount of the
Global Preferred Securities representing the Preferred Securities, in exchange
for such Global Preferred Securities. An Administrative Trustee also shall
execute, and the Property Trustee also shall authenticate and deliver,
Definitive Preferred Securities, in any authorized denominations, in an
aggregate stated liquidation amount equal to the aggregate stated liquidation
amount of the Global Preferred Securities representing the Preferred Securities,
in exchange for such Global Preferred Securities, if (1) the Sponsor in its sole
discretion elects to cause the issuance of the Preferred Securities in
definitive form or (2) there shall have occurred and be continuing any event
which after notice or lapse of time or both would be a Trust Enforcement Event.

     (h) The Administrative Trustees at any time and in their sole discretion
may determine that the Preferred Securities issued in the form of one or more
Global Preferred Securities shall no longer be represented by Global Preferred
Securities. In such event an Administrative Trustee on behalf of the Trust shall
execute, and the Property Trustee shall authenticate and deliver, Definitive
Preferred Securities, in any authorized denominations, in an aggregate stated
liquidation amount equal to the aggregate stated liquidation amount of the
Global Preferred Securities representing the Preferred Securities, in exchange
for such Global Preferred Securities.

     (i) Notwithstanding any other provisions of this Trust Agreement (other
than the provisions set forth in Section 7.1), Global Preferred Securities may
not be transferred as a whole except by the Clearing Agency to a nominee of the
Clearing Agency or by a nominee of the Clearing Agency to the Clearing Agency or
another nominee of the Clearing Agency or by the Clearing Agency or any such
nominee to a successor Clearing Agency or a nominee of such successor Clearing
Agency.

     (j) Interests of Preferred Security Beneficial Owners may be transferred or
exchanged for Preferred Securities not represented by a Global Preferred
Security, and Preferred Securities not represented by a Global Preferred
Security may be transferred or exchanged for a Global Preferred Security or
Securities, in accordance with rules of the Clearing Agency and the provisions
of Section 7.1.

     The Registrar shall retain for at least two years copies of all letters,
notices and other written communications received pursuant to this Section 7.1.
The Issuers shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Registrar.

                             TRANSFER OF SECURITIES

SECTION 7.1 TRANSFER OF SECURITIES.

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

     (b) Subject to this Section 7.1 and Section 6.22, the Preferred Securities
shall be freely transferable.

     (c) The Common Securities shall not be transferable except as provided in
the Indenture.

     (d) The Trust shall cause to be kept at the Corporate Trust Office the
books and records in which, subject to such reasonable regulations as it may
prescribe, the Trust shall provide for the registration of Preferred Securities
and of transfers of Preferred Securities.

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

     (f) At the option of the Holder, Preferred Securities may be exchanged for
other Preferred Securities of any authorized denominations and of a like
aggregate stated liquidation amount, upon surrender of the Preferred Securities
to be exchanged at such office or agency. Whenever any Preferred Securities are
so surrendered for exchange, an Administrative Trustee shall execute, and the
Property Trustee shall authenticate and deliver, the Preferred Securities that
the Holder making the exchange is entitled to receive.

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

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

     (i) If the Preferred Securities are to be redeemed in part, neither the
Administrative Trustees nor the Trust shall be required to register the transfer
of or exchange any Preferred Securities:

                                       66
<PAGE>

          (i) during a period beginning on the opening of business 15 days
     before the day of the mailing of a Redemption Notice or any notice of
     selection of Securities for redemption; or

          (ii) so selected for redemption, except the unredeemed portion of any
     such Preferred Securities being redeemed in part.

SECTION 7.2 SEPARATION AND REJOINING OF UNITS.

     At any time after issuance, the Preferred Security and Warrant components
of any Unit may be separated by the holder and thereafter transferred
separately. In the event of any separation of the components of a Unit:

          (a) if such Unit is represented by a definitive certificate, the
     holder shall present such definitive certificate to the Unit Agent for
     cancellation and the Unit Agent shall so notify the Unit registrar and
     shall return the Preferred Security component of such Unit to the Property
     Trustee with an instruction to countersign and deliver to, or upon the
     instruction of, such holder a separated Preferred Security bearing the
     separate "CUSIP" number assigned to the Preferred Security; and

          (b) if such Unit is represented by a global certificate, the Unit
     Agent shall make the necessary endorsement to the "Schedule of Exchanges of
     Interests of Global Preferred Security" attached to the global unit
     certificate or otherwise comply with its procedures to reduce the amount of
     Units represented thereby and shall instruct the Property Trustee to effect
     a corresponding increase in the Preferred Securities represented by the
     Global Preferred Securities bearing a separate "CUSIP" number.

     Once separated, a Preferred Security and Warrant may be rejoined to form a
Unit. In the event a holder of a Preferred Security and a Warrant desires to
rejoin a Unit:

          (i) if the constituent components are represented by definitive
     certificates, the holder shall present (A) the Preferred Security to the
     Property Trustee and (B) the Warrant to the Warrant Agent, in each case for
     cancellation and the Property Trustee and the Warrant Agent shall so notify
     the Unit Agent, who shall in turn so notify the Unit registrar with an
     instruction for the Unit registrar to countersign and deliver to, or upon
     the instruction of, such holder a Unit certificate bearing the separate
     "CUSIP" number assigned to the Units; and

          (ii) if the constituent components are represented by global
     certificates, each of the Property Trustee and the Warrant Agent shall make
     the necessary endorsement to their respective global certificates or
     otherwise comply with their procedures to reduce the amount of Preferred
     Securities and Warrants, respectively, represented thereby and shall
     instruct the Unit Agent to effect a corresponding increase in the Units
     represented by the global unit certificate bearing a separate "CUSIP"
     number. The Property Trustee shall make such other necessary endorsements
     to the Global Preferred Securities consistent with the terms of this
     agreement to reflect the appropriate number of Units and Preferred
     Securities, as appropriate, represented thereby.

                                       67

SECTION 7.3 BOOK-ENTRY INTERESTS.

     Unless Definitive Preferred Securities have been issued to the Preferred
Security Beneficial Owners pursuant to Sections 6.21(e) and 6.21(f):

          (a) the provisions of this Section 7.3 shall be in full force and
     effect;

          (b) to the extent that the provisions of this Section 7.3 conflict
     with any other provisions of this Trust Agreement, the provisions of this
     Section 7.3 shall control;

          (c) the Trust, the Sponsor and the Trustees shall be entitled to deal
     with the Clearing Agency for all purposes of this Trust Agreement
     (including the payment of Distributions on the Global Preferred Securities
     and receiving approvals, votes or consents hereunder) as the Holder of the
     Preferred Securities and the absolute owner of the Global Preferred
     Securities for all purposes whatsoever and shall have no obligation to the
     Preferred Security Beneficial Owners; and

          (d) the rights of the Preferred Security Beneficial Owners shall be
     exercised only through the Clearing Agency and shall be limited to those
     established by law and agreements between such Preferred Security
     Beneficial Owners and the Clearing Agency and/or the Clearing Agency
     Participants. The Clearing Agency shall make book-entry transfers among the
     Clearing Agency Participants and shall receive and transmit payments of
     Distributions on the Global Preferred Securities to such Clearing Agency
     Participants; provided that solely for the purposes of determining whether
     the Holders of the requisite liquidation amount of Preferred Securities
     have voted on any matter provided for in this Trust Agreement, so long as
     Definitive Preferred Securities have not been issued and the Preferred
     Securities remain in the form of one or more Global Preferred Securities,
     the Trustees may rely conclusively on, and shall be protected in relying
     on, any written instrument (including a proxy) delivered to the Trustees by
     the Clearing Agency setting forth the votes of the Preferred Security
     Beneficial Owners or assigning the right to vote on any matter to any other
     Persons either in whole or in part.

SECTION 7.4 NOTICES TO CLEARING AGENCY.

     Whenever a notice or other communication to the Preferred Security Holders
is required under this Trust Agreement, the Trustees shall give all such notices
and communications specified herein to be given to the Holders of Global
Preferred Securities to the Clearing Agency, and shall have no notice
obligations to the Preferred Security Beneficial Owners.

SECTION 7.5 APPOINTMENT OF SUCCESSOR CLEARING AGENCY.

     If any Clearing Agency elects to discontinue its services as securities
depositary with respect to the Preferred Securities, the Administrative Trustees
may, in their sole discretion, appoint a successor Clearing Agency with respect
to such Preferred Securities.

                                  ARTICLE VIII
                    DISSOLUTION AND TERMINATION OF THE TRUST

SECTION 8.1 DISSOLUTION AND TERMINATION OF THE TRUST.

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

          (i) the bankruptcy of the Sponsor;

          (ii) the filing of a certificate of dissolution or its equivalent with
     respect to the Sponsor; or the revocation of the Sponsor's charter and the
     expiration 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 by a court of competent jurisdiction;

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

          (v) the written notice from the Sponsor directing the Property Trustee
     to distribute the Debentures to the Holders in exchange for all of the
     Securities; provided that the Sponsor has provided to the Property Trustee
     an Opinion of a Counsel experienced in such matters to the effect that the
     Holders will not recognize any gain or loss for United States federal
     income tax purposes as a result of the distribution of Debentures and the
     dissolution of the Trust;

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

          (vii) the expiration of the term of the Trust provided in Section
     3.13.

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

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

SECTION 8.2 LIQUIDATION DISTRIBUTION UPON DISSOLUTION OR TERMINATION OF THE
            TRUST.

     (a) In the event of any voluntary or involuntary dissolution or termination
of the Trust pursuant to Section 8.1(a)(i), 8.1(a)(ii), 8.1(a)(iii) or 8.1(a)(v)
(each a "Liquidation"), the Trust shall be liquidated by the Administrative
Trustees as expeditiously as the Administrative Trustees determine to be
possible by distributing to the Holders, after satisfaction of liabilities to

                                       69
<PAGE>

creditors of the Trust, if any, as provided by applicable law, Debentures in an
aggregate 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 in exchange for such Securities.

     (b) If, notwithstanding the other provisions of this Section 8.2,
distribution of the Debentures in the manner set forth in Section 8.2(a)(i) is
determined by the Property Trustee not to be practical, the assets of the Trust
shall be liquidated, and the Trust shall be wound-up by the Administrative
Trustees in such manner as the Administrative Trustees determine. In such event,
the Holders shall be entitled to receive out of the assets of the Trust
available for distribution to the Holders, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, an amount equal to the
Accreted Value of the Securities plus accumulated and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"). If, upon any such Liquidation, the Liquidation Distribution can
be paid only in part because the Trust has insufficient assets available to pay
the aggregate Liquidation Distribution in full, then the amounts payable
directly by the Trust on the Securities shall be paid on a Pro Rata basis,
provided that if an Indenture Event of Default has occurred and is continuing,
then the Preferred Securities shall have a preference over the Common Securities
with regard to the Liquidation Distribution.

     (c) Notice of any distribution of Debentures in exchange for the Securities
(an "Exchange Notice"), which notice shall be irrevocable, shall be given by the
Administrative Trustees on behalf of the Trust by mail to each Holder at least
30 but no more than 60 days before the date fixed for such distribution. For
purposes of the calculation of the date of distribution and the dates on which
notices are given pursuant to this Section 8.2(c), an Exchange Notice shall be
deemed to be given on the day such notice is first mailed by first-class mail,
postage prepaid, to the Holders. Each Exchange Notice shall be addressed to the
Holders at the address of each such Holder appearing on the books and records of
the Trust. No defect in the Exchange Notice or in the mailing of either thereof
with respect to any Holder shall affect the validity of the distribution
proceedings with respect to any other Holder.

     (d) On and from the date fixed for any distribution of Debentures upon
dissolution of the Trust:

          (i) the Securities no longer shall be deemed to be outstanding;

          (ii) the Clearing Agency or its nominee (or any successor Clearing
     Agency or its nominee), as the Holder of the Preferred Securities, will
     receive a registered global certificate or certificates representing the
     Debentures to be delivered upon such distribution; and

          (iii) any certificates representing Securities not held by the
     Clearing Agency or its nominee (or any successor Clearing Agency or its
     nominee) shall be deemed to represent Debentures having an aggregate
     principal amount equal to the aggregate liquidation amount of such
     Securities and bearing accrued and unpaid interest in an amount equal to
     the accumulated and unpaid Distributions on such Securities, until such

                                       70
<PAGE>

     certificates are presented for cancellation, at which time the Debenture
     Issuer shall issue, and the Debenture Trustee shall authenticate, a
     certificate representing such Debentures.

                                   ARTICLE IX
             LIMITATION OF LIABILITY OF THE HOLDERS, THE TRUSTEES OR
                                     OTHERS

SECTION 9.1 LIABILITY.

     (a) Except as expressly set forth in this Trust Agreement, the Guarantee
and the terms of the Securities, the Sponsor shall not be:

          (i) personally liable for the return of any portion of the capital
     contributions (or any return thereon) of the Holders which shall be made
     solely from assets of the Trust; and

          (ii) required to pay to the Trust or to any Holder any deficit upon
     dissolution of the Trust or otherwise.

     (b) The Sponsor, in its capacity as Debenture Issuer, shall be liable for
all of the debts and obligations of the Trust (other than in respect of the
Securities) to the extent such debts and obligations are not satisfied out of
the Trust's assets.

     (c) Pursuant to Section 3803(a) of the Delaware Business Trust Act, the
Holders shall be entitled to the same limitation of personal liability extended
to stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.

SECTION 9.2 EXCULPATION.

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

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

SECTION 9.3 FIDUCIARY DUTY.

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

     (b) Unless otherwise expressly provided herein:

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

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

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) Pursuant to the Indenture, the Debenture Issuer shall indemnify, to
the fullest extent permitted by law, any Debenture Issuer Indemnified Person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the Trust) by
reason of the fact that he is or was a Debenture Issuer Indemnified

                                       72
<PAGE>

Person against expenses (including attorneys' fees and expenses), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Trust, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the Debenture Issuer Indemnified Person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Trust, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

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

          (iii) To the extent that a Debenture Issuer Indemnified Person shall
     be successful on the merits or otherwise (including dismissal of an action
     without prejudice or the settlement of an action without admission of
     liability) in defense of any action, suit or proceeding referred to in
     paragraphs (i) and (ii) of this Section 9.4(a), or in defense of any claim,
     issue or matter therein, he shall be indemnified, to the fullest extent
     permitted by law, against expenses (including attorneys' fees and expenses)
     actually and reasonably incurred by him in connection therewith.

          (iv) 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 Debenture 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:

               (A) by a majority vote of a Quorum of the Administrative Trustees
          who were not parties to such action, suit or proceeding;

                                       73
<PAGE>

               (B) 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

               (C) by the Holders of the Common Securities.

          (v) Expenses (including attorneys' fees and expenses) incurred by a
     Debenture 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
     Debenture Issuer Indemnified Person to repay such amount if it shall
     ultimately be determined that he is not entitled to be indemnified by the
     Debenture Issuer as authorized in this Section 9.4(a). Notwithstanding the
     foregoing, no advance shall be made by the Debenture Issuer if a
     determination is reasonably and promptly made:

               (A) by a majority vote of a Quorum of disinterested
          Administrative Trustees;

               (B) 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

               (C) the Holder of the Common Securities,

that, based upon the facts known to the Administrative Trustees, independent
legal counsel or Holders of the Common Securities at the time such determination
is made, such Debenture Issuer Indemnified Person acted in bad faith or in a
manner that such person did not believe to be in or not opposed to the best
interests of the Trust, or, with respect to any criminal proceeding, that such
Debenture Issuer Indemnified Person believed or had reasonable cause to believe
his conduct was unlawful.

     In no event shall any advance be made in instances where the Administrative
Trustees, independent legal counsel or Holders of the Common Securities
reasonably determine that such person deliberately breached his duty to the
Trust or the Holders.

          (vi) 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 Holders of the Preferred Securities 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 Debenture 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.

                                       74
<PAGE>

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

          (viii) For purposes of this Section 9.4(a), references to "the Trust"
     shall include, in addition to the resulting or surviving entity, any

     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

          (ix) The indemnification and advancement of expenses provided by, or
     granted pursuant to, this Section 9.4(a) shall, unless otherwise provided

     being referred to as a "Fiduciary Indemnified Person")

for, and to hold each Fiduciary Indemnified Person harmless against, any and all
loss, liability, damage, claim or expense including taxes (other than taxes
based on the income of such Fiduciary Indemnified Person) incurred without gross
negligence (or, in the case of the Property Trustee, negligence) or bad faith 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

SECTION 9.5 OUTSIDE BUSINESSES.

          Any Covered Person, the Sponsor, the Delaware Trustee, the Property
     Trustee and any Agent (subject to Section 5.3(c)) may engage in or possess
     an interest in other business ventures of any nature or description,
     independently or with others, similar or dissimilar to the business of the
     Trust, and the Trust and the Holders 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

     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, the Property
     Trustee and any Agent 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, the Property Trustee and any Agent 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

     obligations of the Sponsor or its Affiliates.

SECTION 10.1 FISCAL YEAR.

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

SECTION 10.2 CERTAIN ACCOUNTING MATTERS.

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

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

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

                                       76

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

SECTION 10.3 BANKING.

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

SECTION 10.4 WITHHOLDING.

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

SECTION 11.2 MEETINGS OF THE HOLDERS; ACTION BY WRITTEN CONSENT.

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

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

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

          (ii) Each Holder may authorize any Person to act for it by proxy on
     any and all matters in which such Holder is entitled to participate,
     including waiving notice of any meeting, or voting or participating at a
     meeting. No proxy shall be valid after the expiration of eleven months from
     the date thereof unless otherwise provided in the proxy. Every proxy shall
     be revocable at the pleasure of the Holder 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
     were stockholders of a Delaware corporation.

          (iii) Each meeting of the Holders shall be conducted by the
     Administrative Trustees or by such other Person that the Administrative
     Trustees may designate.

                                       80
<PAGE>

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