            necessary or advisable in order to comply with the applicable laws
            of any such States in connection with the sale of the Capital
            Securities; and

                  (iii) the taking of any other actions necessary or desirable
            to carry out any of the foregoing activities.

            (d) Notwithstanding anything herein to the contrary, the
Administrators, the Institutional Trustee and the Holders of a Majority in
liquidation amount of the Common Securities are authorized and directed to
conduct the affairs of the Trust and to operate the Trust so that (i) the Trust
will not be deemed to be an Investment Company (in the case of the Institutional
Trustee, to the actual knowledge of a Responsible Officer), and (ii) the Trust
will not fail to be classified as a grantor trust for United States federal
income tax purposes (in the case of the Institutional Trustee, to the actual
knowledge of a Responsible Officer) and (iii) the Trust will not take any action
inconsistent with the treatment of the Debentures as indebtedness of the
Debenture Issuer for United States federal income tax purposes (in the case of
the Institutional Trustee, to the actual knowledge of a Responsible Officer). In
this connection, the Institutional Trustee, the Administrators and the Holders
of a Majority in liquidation amount of the Common Securities are authorized to
take any action, not inconsistent with applicable laws or this Declaration, as
amended from time to time, that each of the Institutional Trustee, the
Administrators and such Holders determine in their discretion to be necessary or
desirable for such purposes, even if such action adversely affects the interests
of the Holders of the Capital Securities.

            (e) All expenses incurred by the Administrators or the Trustees
pursuant to this Section 2.6 shall be reimbursed by the Sponsor, and the
Trustees shall have no obligations with respect to such expenses.

            (f) The assets of the Trust shall consist of the Trust Property.

            (g) Legal title to all Trust Property shall be vested at all times
in the Institutional Trustee (in its capacity as such) and shall be held and
administered by the Institutional Trustee for the benefit of the Trust in
accordance with this Declaration.

            (h) If the Institutional Trustee or any Holder has instituted any
proceeding to enforce any right or remedy under this Declaration and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Institutional Trustee or to such Holder, then and in
every such case the Sponsor, the Institutional Trustee and the Holders shall,
subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and
remedies of the Institutional Trustee and the Holders shall continue as though
no such proceeding had been instituted.

      SECTION 2.7. Prohibition of Actions by the Trust and the Trustees. The
Trust shall not, and the Institutional Trustee and the Administrators shall not,
and the Administrators shall cause the Trust not to, engage in any activity
other than as required or authorized by this Declaration. In particular, the
Trust shall not, and the Institutional Trustee and the Administrators shall not
cause the Trust to:

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

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

            (c) possess Trust Property for other than a Trust purpose;

            (d) make any loans or incur any indebtedness other than loans
represented by the Debentures;

            (e) possess any power or otherwise act in such a way as to vary the
Trust Property or the terms of the Securities;

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

            (g) other than as provided in this Declaration (including Annex I),
(i) direct the time, method and place of exercising any trust or power conferred
upon the Debenture Trustee with respect to the Debentures, (ii) waive any past
default that is waivable under the Indenture, (iii) exercise any right to
rescind or annul any declaration that the principal of all the Debentures shall
be due and payable, or (iv) consent to any amendment, modification or
termination of the Indenture or the Debentures where such consent shall be
required unless the Trust shall have received a written opinion of counsel
experienced in such matters to the effect that such amendment, modification or
termination will not cause the Trust to cease to be classified as a grantor
trust for United States federal income tax purposes.

      SECTION 2.8. Powers and Duties of the Institutional Trustee.

            (a) The legal title to the Debentures shall be owned by and held of
record in the name of the Institutional Trustee in trust for the benefit of the
Trust. The right, title and interest of the Institutional Trustee to the
Debentures shall vest automatically in each Person who may hereafter be
appointed as Institutional Trustee in accordance with Section 4.7. Such vesting
and cessation of title shall be effective whether or not conveyancing documents
with regard to the Debentures have been executed and delivered.

            (b) The Institutional Trustee shall not transfer its right, title
and interest in the Debentures to the Administrators or to the Delaware Trustee.

            (c) The Institutional Trustee shall:

                  (i) establish and maintain a segregated non-interest bearing
            trust account (the "Property Account") in the United States (as
            defined in Treasury Regulations Section 301.7701-7), in the name of
            and under the exclusive control of the Institutional Trustee, and
            maintained in the Institutional Trustee's trust department, on
            behalf of the Holders of the Securities and, upon the receipt of
            payments of funds made in respect of the Debentures held by the
            Institutional Trustee, deposit such funds into the Property Account
            and make payments to the Holders of the Capital Securities and
            Holders of the Common Securities from the Property Account in
            accordance with Section 5.1. Funds in the Property Account shall be
            held uninvested until disbursed in accordance with this Declaration;

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

                  (iii) upon written notice of distribution issued by the
            Administrators in accordance with the terms of the Securities,
            engage in such ministerial activities as shall be necessary or
            appropriate to effect the distribution of the Debentures to Holders
            of Securities upon the occurrence of certain circumstances pursuant
            to the terms of the Securities.

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

            (e) The Institutional Trustee may bring or defend, pay, collect,
compromise, arbitrate, resort to legal action with respect to, or otherwise
adjust claims or demands of or against, the Trust (a "Legal Action") which arise
out of or in connection with an Event of Default of which a Responsible Officer
of the Institutional Trustee has actual knowledge or the Institutional Trustee's
duties and obligations under this Declaration or the Trust Indenture Act;
provided, however, that if an Event of Default has occurred and is continuing
and such event is attributable to the failure of the Debenture Issuer to pay
interest or premium, if any, on or principal of the Debentures on the date such
interest, premium, if any, or principal is otherwise payable (or in the case of
redemption, on the redemption date), then a Holder of the Capital Securities may
directly institute a proceeding for enforcement of payment to such Holder of the

                                      -15-

<PAGE>

principal of or premium, if any, or interest on the Debentures having a
principal amount equal to the aggregate liquidation amount of the Capital
Securities of such Holder (a "Direct Action") on or after the respective due
date specified in the Debentures. In connection with such Direct Action, the
rights of the Holders of the Common Securities will be subrogated to the rights
of such Holder of the Capital Securities to the extent of any payment made by
the Debenture Issuer to such Holder of the Capital Securities in such Direct
Action; provided, however, that a Holder of the Common Securities may exercise
such right of subrogation only if no Event of Default with respect to the
Capital Securities has occurred and is continuing.

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

                  (i) the Trust has been completely liquidated and the proceeds
            of the liquidation distributed to the Holders of the Securities
            pursuant to the terms of the Securities and this Declaration
            (including Annex I) and the certificate of cancellation referenced
            in Section 7.1(b) has been filed; or

                  (ii) a Successor Institutional Trustee has been appointed and
            has accepted that appointment in accordance with Section 4.7.

            (g) The Institutional Trustee shall have the legal power to exercise
all of the rights, powers and privileges of a holder of the Debentures under the
Indenture and, if an Event of Default occurs and is continuing, the
Institutional Trustee may, for the benefit of Holders of the Securities, enforce
its rights as holder of the Debentures subject to the rights of the Holders
pursuant to this Declaration (including Annex I) and the terms of the
Securities.

            (h) The Institutional Trustee must exercise the powers set forth in
this Section 2.8 in a manner that is consistent with the purposes and functions
of the Trust set out in Section 2.3, and the Institutional Trustee shall not
take any action that is inconsistent with the purposes and functions of the
Trust set out in Section 2.3.

      SECTION 2.9. Certain Duties and Responsibilities of the Trustees and the
Administrators.

            (a) The Institutional Trustee, before the occurrence of any Event of
Default (of which the Institutional Trustee has knowledge (as provided in
Section 2.10(m) hereof)) and after the curing of all Events of Default that may
have occurred, shall undertake to perform only such duties as are specifically
set forth in this Declaration and no implied covenants shall be read into this
Declaration against the Institutional Trustee. In case an Event of Default (of
which the Institutional Trustee has knowledge (as provided in Section 2.10(m)
hereof)), has occurred (that has not been cured or waived pursuant to Section
6.8), the Institutional Trustee shall exercise such of the rights and powers
vested in it by this Declaration, and use the same degree of care and skill in
their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

            (b) The duties and responsibilities of the Trustees and the
Administrators shall be as provided by this Declaration and, in the case of the
Institutional Trustee, by the Trust Indenture Act. Notwithstanding the
foregoing, no provision of this Declaration shall require any Trustee or
Administrator to expend or risk its own funds or otherwise incur any financial
liability

                                      -16-

<PAGE>

in the performance of any of its duties hereunder, or in the exercise of any of
its rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity satisfactory to it against such
risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Declaration relating to the
conduct or affecting the liability of or affording protection to the Trustees or
the Administrators shall be subject to the provisions of this Article. Nothing
in this Declaration shall be construed to release a Trustee from liability for
its own negligent action, its own negligent failure to act, or its own willful
misconduct or bad faith. Nothing in this Declaration shall be construed to
release an Administrator from liability for its own gross negligent action, its
own gross negligent failure to act, or its own willful misconduct or bad faith.
To the extent that, at law or in equity, a Trustee or an Administrator has
duties and liabilities relating to the Trust or to the Holders, such Trustee or
Administrator shall not be liable to the Trust or to any Holder for such
Trustee's or Administrator's good faith reliance on the provisions of this
Declaration. The provisions of this Declaration, to the extent that they
restrict the duties and liabilities of the Administrators or the Trustees
otherwise existing at law or in equity, are agreed by the Sponsor and the
Holders to replace such other duties and liabilities of the Administrators or
the Trustees.

            (c) All payments made by the Institutional Trustee or a Paying Agent
in respect of the Securities shall be made only from the revenue and proceeds
from the Trust Property and only to the extent that there shall be sufficient
revenue or proceeds from the Trust Property to enable the Institutional Trustee
or a Paying Agent to make payments in accordance with the terms hereof. Each
Holder, by its acceptance of a Security, agrees that it will look solely to the
revenue and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that the Trustees and the
Administrators are not personally liable to it for any amount distributable in
respect of any Security or for any other liability in respect of any Security.
This Section 2.9(c) does not limit the liability of the Trustees expressly set
forth elsewhere in this Declaration or, in the case of the Institutional
Trustee, in the Trust Indenture Act.

            (d) No provision of this Declaration shall be construed to relieve
the Institutional Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct or bad faith with
respect to matters that are within the authority of the Institutional Trustee
under this Declaration, except that:

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

                  (ii) the Institutional Trustee shall not be liable with
            respect to any action taken or omitted to be taken by it in good
            faith in accordance with the direction of the Holders of not less
            than a Majority in liquidation amount of the Capital Securities or
            the Common Securities, as applicable, relating to the time, method
            and place of conducting any proceeding for any remedy available to
            the Institutional Trustee, or exercising any trust or power
            conferred upon the Institutional Trustee under this Declaration;

                                      -17-

<PAGE>

                  (iii) the Institutional Trustee's sole duty with respect to
            the custody, safe keeping and physical preservation of the
            Debentures and the Property Account shall be to deal with such
            property in a similar manner as the Institutional Trustee deals with
            similar property for its own account, subject to the protections and
            limitations on liability afforded to the Institutional Trustee under
            this Declaration and the Trust Indenture Act;

                  (iv) the Institutional Trustee 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
            Institutional Trustee need not be segregated from other funds held
            by it except in relation to the Property Account maintained by the
            Institutional Trustee pursuant to Section 2.8(c)(i) and except to
            the extent otherwise required by law; and

                  (v) the Institutional Trustee shall not be responsible for
            monitoring the compliance by the Administrators or the Sponsor with
            their respective duties under this Declaration, nor shall the
            Institutional Trustee be liable for any default or misconduct of the
            Administrators or the Sponsor.

      SECTION 2.10. Certain Rights of Institutional Trustee. Subject to the
provisions of Section 2.9.

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

            (b) if (i) in performing its duties under this Declaration, the
Institutional Trustee is required to decide between alternative courses of
action, (ii) in construing any of the provisions of this Declaration, the
Institutional Trustee finds the same ambiguous or inconsistent with any other
provisions contained herein, or (iii) the Institutional Trustee is unsure of the
application of any provision of this Declaration, then, except as to any matter
as to which the Holders of Capital Securities are entitled to vote under the
terms of this Declaration, the Institutional Trustee may deliver a notice to the
Sponsor requesting the Sponsor's opinion as to the course of action to be taken
and the Institutional Trustee shall take such action, or refrain from taking
such action, as the Institutional Trustee in its sole discretion shall deem
advisable and in the best interests of the Holders, in which event the
Institutional Trustee shall have no liability except for its own negligence or
willful misconduct;

            (c) any direction or act of the Sponsor or the Administrators
contemplated by this Declaration shall be sufficiently evidenced by an Officers'
Certificate;

            (d) whenever in the administration of this Declaration, the
Institutional Trustee shall deem it desirable that a matter be proved or
established before undertaking,

                                      -18-

<PAGE>

suffering or omitting any action hereunder, the Institutional Trustee (unless
other evidence is herein specifically prescribed) may, in the absence of bad
faith on its part, request and conclusively rely upon an Officers' Certificate
which, upon receipt of such request, shall be promptly delivered by the Sponsor
or the Administrators;

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

            (f) the Institutional Trustee may consult with counsel of its
selection (which counsel may be counsel to the Sponsor or any of its Affiliates)
and the advice of such counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in reliance thereon and in accordance with such advice; the
Institutional Trustee shall have the right at any time to seek instructions
concerning the administration of this Declaration from any court of competent
jurisdiction;

            (g) the Institutional Trustee shall be under no obligation to
exercise any of the rights or powers vested in it by this Declaration at the
request or direction of any of the Holders pursuant to this Declaration, unless
such Holders shall have offered to the Institutional Trustee security or
indemnity reasonably satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction; provided, that nothing contained in this Section 2.10(g) shall be
taken to relieve the Institutional Trustee, upon the occurrence of an Event of
Default (of which the Institutional Trustee has knowledge (as provided in
Section 2.10(m) hereof)) that has not been cured or waived, of its obligation to
exercise the rights and powers vested in it by this Declaration;

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

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

            (j) whenever in the administration of this Declaration the
Institutional Trustee shall deem it desirable to receive instructions with
respect to enforcing any remedy or right or taking any other action hereunder,
the Institutional Trustee (i) may request instructions from the Holders of the
Common Securities and the Capital Securities, which instructions may be given
only by the Holders of the same proportion in liquidation amount of the Common
Securities and the Capital Securities as would be entitled to direct the
Institutional Trustee under the terms of the Common Securities and the Capital
Securities in respect of such remedy, right or action, (ii) may refrain from
enforcing such remedy or right or taking such other action until such

                                      -19-

<PAGE>

instructions are received, and (iii) shall be fully protected in acting in
accordance with such instructions;

            (k) except as otherwise expressly provided in this Declaration, the
Institutional Trustee shall not be under any obligation to take any action that
is discretionary under the provisions of this Declaration;

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

            (m) the Institutional Trustee shall not be charged with knowledge of
an Event of Default unless a Responsible Officer of the Institutional Trustee
has actual knowledge of such event or the Institutional Trustee receives written
notice of such event from any Holder, except with respect to an Event of Default
pursuant to Sections 5.01(a), 5.01(b) or 5.01(c) of the Indenture (other than an
Event of Default resulting from the default in the payment of Additional
Interest or premium, if any, if the Institutional Trustee does not have actual
knowledge or written notice that such payment is due and payable), of which the
Institutional Trustee shall be deemed to have knowledge;

            (n) any action taken by the Institutional Trustee or its agents
hereunder shall bind the Trust and the Holders of the Securities, and the
signature of the Institutional 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 Institutional Trustee to so act or as to its
compliance with any of the terms and provisions of this Declaration, both of
which shall be conclusively evidenced by the Institutional Trustee's or its
agent's taking such action; and

            (o) no provision of this Declaration shall be deemed to impose any
duty or obligation on the Institutional 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 Institutional 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 Institutional
Trustee shall be construed to be a duty.

      SECTION 2.11. Delaware Trustee. Notwithstanding any other provision of
this Declaration other than Section 4.2, the Delaware Trustee shall not be
entitled to exercise any powers, nor shall the Delaware Trustee have any of the
duties and responsibilities of any of the Trustees or the Administrators
described in this Declaration (except as may be required under the Statutory
Trust Act). Except as set forth in Section 4.2, the Delaware Trustee shall be a
Trustee for the sole and limited purpose of fulfilling the requirements of
Section 3807 of the Statutory Trust Act.

      SECTION 2.12. Execution of Documents. Unless otherwise determined in
writing by the Institutional Trustee, and except as otherwise required by the
Statutory Trust Act, the Institutional Trustee, or any one or more of the
Administrators, as the case may be, is authorized

                                      -20-
<PAGE>

to execute and deliver on behalf of the Trust any documents, agreements,
instruments or certificates that the Trustees or the Administrators, as the case
may be, have the power and authority to execute pursuant to Section 2.6.

      SECTION 2.13. Not Responsible for Recitals or Issuance of Securities. The
recitals contained in this Declaration 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 Declaration, the
Debentures or the Securities.

      SECTION 2.14. Duration of Trust. The Trust, unless dissolved pursuant to
the provisions of Article VII hereof, shall have existence for thirty-five (35)
years from the Closing Date.

      SECTION 2.15. Mergers.

            (a)   The Trust may not consolidate, amalgamate, merge with or into,
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described in this Section 2.15 and except with respect to the distribution of
Debentures to Holders of Securities pursuant to Section 7.1(a)(iv) of the
Declaration or Section 4 of Annex I.

            (b)   The Trust may, with the consent of the Administrators (which
consent will not be unreasonably withheld) and without the consent of the
Institutional Trustee, the Delaware Trustee or the Holders of the Capital
Securities, consolidate, amalgamate, merge with or into, or 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 survivor, such successor entity
            (the "Successor Entity") either:

                        (A) expressly assumes all of the obligations of the
                  Trust under the Securities; or

                        (B) substitutes for the Securities other securities
                  having substantially the same terms as the Securities (the
                  "Successor Securities") so that the Successor Securities rank
                  the same as the Securities rank with respect to Distributions
                  and payments upon Liquidation, redemption and otherwise;

                  (ii)  the Sponsor expressly appoints a trustee of the
            Successor Entity that possesses the same powers and duties as the
            Institutional Trustee;

                  (iii) the Capital Securities or any Successor Securities
            (excluding any securities substituted for the Common Securities) are
            listed or quoted, or any Successor Securities will be listed or
            quoted upon notification of issuance, on any

                                      -21-
<PAGE>

            national securities exchange or with another organization on which
            the Capital Securities are then listed or quoted, if any;

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

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

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

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

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

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

                        (C) following such merger, consolidation, amalgamation,
                  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) the Sponsor guarantees the obligations of such
            Successor Entity under the Successor Securities to the same extent
            provided by the Guarantee, the Debentures and this Declaration; and

                  (ix)  prior to such merger, consolidation, amalgamation,
            replacement, conveyance, transfer or lease, the Institutional
            Trustee shall have received an Officers' Certificate of the
            Administrators and an opinion of counsel, each to the effect that
            all conditions precedent of this paragraph (b) to such transaction
            have been satisfied.

consolidate, amalgamate, merge with or into, or be replaced by, or convey,
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 consolidate,
amalgamate, merge with or into, or replace it if such consolidation,
amalgamation, merger, replacement, conveyance, transfer or lease would cause the
Trust or Successor Entity to be classified as other than a grantor trust for
United States federal income tax purposes.

            corporation or national association publishes reports of condition
            at least annually, pursuant to law or to the requirements of the

      There shall at all times be at least one Administrator. Except where a
requirement for action by a specific number of Administrators is expressly set

the Administrators may be exercised by, or with the consent of, any one such
Administrator acting alone.

      SECTION 4.6. Initial Delaware Trustee. The initial Delaware Trustee shall
be Chase Bank USA, National Association.

      SECTION 4.7. Appointment, Removal and Resignation of the Trustees and the
Administrators.

            (a)   No resignation or removal of any Trustee (the "Relevant
Trustee") and no appointment of a successor Trustee pursuant to this Article
shall become effective until the acceptance of appointment by the successor
Trustee in accordance with the applicable requirements of this Section 4.7.

            (b)   Subject to Section 4.7(a), a Relevant Trustee may resign at
any time by giving written notice thereof to the Holders of the Securities and
by appointing a successor Relevant Trustee, except in the case of the Delaware
Trustee's successor which shall be appointed by Holders of a Majority in
liquidation amount of the Common Securities. Upon the resignation of the
Institutional Trustee, the Institutional Trustee shall appoint a successor by
requesting from at least three Persons meeting the eligibility requirements
their expenses and charges to serve as the successor Institutional Trustee on a
form provided by the Administrators, and selecting the Person who agrees to the
lowest reasonable expense and charges (the "Successor Institutional Trustee").
If the instrument of acceptance by the successor Relevant Trustee required by
this Section 4.7 shall not have been delivered to the Relevant Trustee within 60
days after the giving of such notice of resignation or delivery of the
instrument of removal, the Relevant Trustee may petition, at the expense of the
Trust, any federal, state or District of Columbia court of competent
jurisdiction for the appointment of a successor Relevant Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper, appoint
a Relevant Trustee. The Institutional Trustee shall have no liability for the
selection of such successor pursuant to this Section 4.7.

            (c)   Unless an Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by an act of the Holders of a
Majority in liquidation amount of the Common Securities. If any Trustee shall be
so removed, the Holders of the Common Securities, by act of the Holders of a
Majority in liquidation amount of the Common Securities delivered to the
Relevant Trustee, shall promptly appoint a successor Relevant Trustee, and such
successor Trustee shall comply with the applicable requirements of this Section
4.7. If an Event

                                      -25-
<PAGE>

of Default shall have occurred and be continuing, the Institutional Trustee or
the Delaware Trustee, or both of them, may be removed by the act of the Holders
of a Majority in liquidation amount of the Capital Securities, delivered to the
Relevant Trustee (in its individual capacity and on behalf of the Trust). If any
Trustee shall be so removed, the Holders of Capital Securities, by act of the
Holders of a Majority in liquidation amount of the Capital Securities then
outstanding delivered to the Relevant Trustee, shall promptly appoint a
successor Relevant Trustee or Trustees, and such successor Trustee shall comply
with the applicable requirements of this Section 4.7. If no successor Relevant
Trustee shall have been so appointed by the Holders of a Majority in liquidation
amount of the Capital Securities and accepted appointment in the manner required
by this Section 4.7 within 30 days after delivery of an instrument of removal,
the Relevant Trustee or any Holder who has been a Holder of the Securities for
at least six months may, on behalf of himself and all others similarly situated,
petition any federal, state or District of Columbia court of competent
jurisdiction for the appointment of a successor Relevant Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper, appoint
a successor Relevant Trustee or Trustees.

            (d)   The Institutional Trustee shall give notice of each
resignation and each removal of a Trustee and each appointment of a successor
Trustee to all Holders and to the Sponsor. Each notice shall include the name of
the successor Relevant Trustee and the address of its Corporate Trust Office if
it is the Institutional Trustee.

            (e)   Notwithstanding the foregoing or any other provision of this
Declaration, in the event a Delaware Trustee who is a natural person dies or is
adjudged by a court to have become incompetent or incapacitated, the vacancy
created by such death, incompetence or incapacity may be filled by the
Institutional Trustee (provided the Institutional Trustee satisfies the
requirements of a Delaware Trustee as set forth in Section 4.2) following the
procedures in this Section 4.7 (with the successor being a Person who satisfies
the eligibility requirement for a Delaware Trustee set forth in this
Declaration) (the "Successor Delaware Trustee").

            (f)   In case of the appointment hereunder of a successor Relevant
Trustee, the retiring Relevant Trustee and each successor Relevant Trustee with
respect to the Securities shall execute and deliver an amendment hereto wherein
each successor Relevant Trustee shall accept such appointment and which (a)
shall contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee with respect to the
Securities and the Trust and (b) shall add to or change any of the provisions of
this Declaration as shall be necessary to provide for or facilitate the
administration of the Trust by more than one Relevant Trustee, it being
understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee; but,
on request of the Trust or any successor Relevant Trustee, such retiring
Relevant Trustee shall duly assign, transfer and deliver to such successor
Relevant Trustee all Trust Property, all proceeds thereof and money held by such
retiring Relevant Trustee hereunder with respect to the Securities and the Trust
subject to the payment of all unpaid fees, expenses and indemnities of such
retiring Relevant Trustee.

                                      -26-
<PAGE>

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

            (h)   The Holders of the Capital Securities will have no right to
vote to appoint, remove or replace the Administrators, which voting rights are
vested exclusively in the Holders of the Common Securities.

            (i)   Any successor Delaware Trustee shall file an amendment to the
Certificate of Trust with the Secretary of State of the State of Delaware
identifying the name and principal place of business of such Delaware Trustee in
the State of Delaware.

      SECTION 4.8. Vacancies Among Trustees. If a Trustee ceases to hold office
for any reason and the number of Trustees is not reduced pursuant to Section
4.1, or if the number of Trustees is increased pursuant to Section 4.1, a
vacancy shall occur. A resolution certifying the existence of such vacancy by
the Trustees or, if there are more than two, a majority of the Trustees shall be
conclusive evidence of the existence of such vacancy. The vacancy shall be
filled with a Trustee appointed in accordance with Section 4.7.

      SECTION 4.9. 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 Declaration. Whenever a vacancy in the number
of Trustees shall occur, until such vacancy is filled by the appointment of a
Trustee in accordance with Section 4.7, the Institutional Trustee shall have all
the powers granted to the Trustees and shall discharge all the duties imposed
upon the Trustees by this Declaration.

      SECTION 4.10. Meetings of the Trustees and the Administrators. Meetings of
the Trustees or the Administrators shall be held from time to time upon the call
of any Trustee or Administrator, as applicable. Regular meetings of the Trustees
and the Administrators, respectively, may be in person in the United States or
by telephone, at a place (if applicable) and time fixed by resolution of the
Trustees or the Administrators, as applicable. Notice of any in-person meetings
of the Trustees or the Administrators shall be hand delivered or otherwise
delivered in writing (including by facsimile, with a hard copy by overnight
courier) not less than 48 hours before such meeting. Notice of any telephonic
meetings of the Trustees or the Administrators 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 a Trustee or an
Administrator, as the case may be, at a meeting shall constitute a waiver of
notice of such meeting except where a Trustee or an Administrator, as the case
may be, 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 Declaration, any action of
the Trustees or the Administrators, as the case may be, may be taken at a
meeting by vote of a majority of the Trustees or the Administrators present
(whether in person or by telephone) and eligible to vote with respect to such
matter; provided, that, in the case of the Administrators, a Quorum is present,
or without a meeting by the unanimous written consent of

                                      -27-
<PAGE>

the Trustees or the Administrators, as the case may be. Meetings of the Trustees
and the Administrators together shall be held from time to time upon the call of
any Trustee or Administrator.

      SECTION 4.11. Delegation of Power.

            (a)   Any Trustee or any Administrator, as the case may be, may, by
power of attorney consistent with applicable law, delegate to any other natural
person over the age of 21 that is a U.S. Person his or her power for the purpose
of executing any documents, instruments or other writings contemplated in
Section 2.6.

            (b)   The Trustees shall have power to delegate from time to time to
such of their number or to any officer of the Trust that is a U.S. Person, the
doing of such things and the execution of such instruments or other writings
either in the name of the Trust or the names of the Trustees or otherwise as the
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 4.12. Merger, Conversion, Consolidation or Succession to Business.
Any Person into which the Institutional Trustee or the Delaware Trustee, as the
case maybe, may be merged or converted or with which either may be consolidated,
or any Person resulting from any merger, conversion or consolidation to which
the Institutional Trustee or the Delaware Trustee, as the case may be, shall be
a party, or any Person succeeding to all or substantially all the corporate
trust business of the Institutional Trustee or the Delaware Trustee, as the case
may be, shall be the successor of the Institutional Trustee or the Delaware
Trustee, as the case may be, hereunder, 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 and,
provided, further, that such Person shall file an amendment to the Certificate
of Trust with the Secretary of State of the State of Delaware as contemplated in
Section 4.7(i).

                                  DISTRIBUTIONS

      SECTION 5.1. Distributions. Holders shall receive Distributions in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Capital Securities and the Common Securities
in accordance with the preferences set forth in their respective terms. If and
to the extent that the Debenture Issuer makes a payment of interest (including
any Additional Interest or Deferred Interest) or premium, if any, on and/or
principal on the Debentures held by the Institutional Trustee (the amount of any
such payment being a "Payment Amount"), the Institutional Trustee shall and is
directed, to the extent funds are available in the Property Account for that
purpose, to make a distribution (a "Distribution") of the Payment Amount to
Holders. For the avoidance of doubt, funds in the Property Account shall not be
distributed to Holders to the extent of any taxes payable by the Trust, in the
case of withholding taxes, as determined by the Institutional Trustee or any
Paying Agent and, in the case of taxes other than withholding tax taxes, as
determined by the Administrators in a written notice to the Institutional
Trustee.

                                   ARTICLE VI
                             ISSUANCE OF SECURITIES

      SECTION 6.1. General Provisions Regarding Securities.

            (a)   The Administrators shall on behalf of the Trust issue one
series of capital securities, evidenced by a certificate substantially in the
form of Exhibit A-1, representing undivided beneficial interests in the assets
of the Trust and having such terms as are set forth in Annex I (the "Capital
Securities"), and one series of common securities, evidenced by a certificate
substantially in the form of Exhibit A-2, representing undivided beneficial
interests in the assets of the Trust and having such terms as are set forth in
Annex I (the "Common Securities"). The Trust shall issue no securities or other
interests in the assets of the Trust other than the Capital Securities and the
Common Securities. The Capital Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities except that, where an Event of
Default has occurred and is continuing, the rights of Holders of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption and otherwise are subordinated to the rights to payment of the
Holders of the Capital Securities.

            (b)   The Certificates shall be signed on behalf of the Trust by one
or more Administrators. Such signature shall be the facsimile or manual
signature of any Administrator. In case any Administrator of the Trust who shall
have signed any of the Securities shall cease to be such Administrator before
the Certificates so signed shall be delivered by the Trust, such Certificates
nevertheless may be delivered as though the person who signed such Certificates
had not ceased to be such Administrator. Any Certificate may be signed on behalf
of the Trust by such person who, at the actual date of execution of such
Security, shall be an Administrator of the Trust, although at the date of the
execution and delivery of the Declaration any such person was not such an
Administrator. A Capital Security shall not be valid until authenticated by the
manual signature of an Authorized Officer of the Institutional Trustee. Such
signature shall be conclusive evidence that the Capital Security has been
authenticated under this Declaration. Upon written order of the Trust signed by
one Administrator, the Institutional Trustee shall authenticate the Capital
Securities for original issue. The Institutional Trustee may appoint an
authenticating agent that is a U.S. Person acceptable to the Trust to
authenticate the Capital Securities. A Common Security need not be so
authenticated and shall be valid upon execution by one or more Administrators.

            (c)   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.

            (d)   Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable, and each Holder thereof shall be entitled to the
benefits provided by this Declaration.

            (e)   Every Person, by virtue of having become a Holder in
accordance with the terms of this Declaration, shall be deemed to have expressly
assented and agreed to the terms of, and shall be bound by, this Declaration and
the Guarantee.

      SECTION 6.2. Paying Agent, Transfer Agent, Calculation Agent and
Registrar.

            (a)   The Trust shall maintain in New York, New York, an office or
agency where the Securities may be presented for payment (the "Paying Agent"),
and an office or agency where Securities may be presented for registration of
transfer or exchange (the "Transfer Agent"). The Trustee hereby appoints the
Institutional Trustee as Paying Agent and Transfer Agent at ITS Unit Trust
Window, 4 New York Plaza, Ground Floor, New York, New York 10004, Attn: ITS
(Houston) - PB Capital Trust II. The Trust shall also keep or cause to be kept a
register for the purpose of registering Securities and transfers and exchanges
of Securities, such register to be held by a registrar (the "Registrar"). The
Administrators may appoint the Paying Agent, the Registrar and the Transfer
Agent, and may appoint one or more additional Paying Agents, one or more
co-Registrars, or one or more co-Transfer Agents in such other locations as it
shall determine. The term "Paying Agent" includes any additional Paying Agent,
the term "Registrar" includes any additional Registrar or co-Registrar and the
term "Transfer Agent" includes any additional Transfer Agent or co-Transfer
Agent. The Administrators may change any Paying Agent, Transfer Agent or
Registrar at any time without prior notice to any Holder. The Administrators
shall notify the Institutional Trustee of the name and address of any Paying
Agent, Transfer Agent and Registrar not a party to this Declaration. The
Administrators hereby initially appoint the Institutional Trustee to act as
Registrar for the Capital Securities and the Common Securities at its Corporate
Trust Office. The Institutional Trustee or any of its Affiliates in the United
States may act as Paying Agent, Transfer Agent or Registrar.

            (b)   The Trust shall also appoint a Calculation Agent, which shall
determine the Coupon Rate in accordance with the terms of the Securities. The
Trust initially appoints the Institutional Trustee as Calculation Agent.

      SECTION 6.3. Form and Dating.

            (a)   The Capital Securities and the Institutional Trustee's
certificate of authentication thereon shall be substantially in the form of
Exhibit A-1, and the Common Securities shall be substantially in the form of
Exhibit A-2, each of which is hereby incorporated in and expressly made a part
of this Declaration. Certificates may be typed, printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrators, as conclusively evidenced by their execution thereof. The
Certificates may have letters, numbers, notations or other marks of
identification or designation and such legends or endorsements 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 Sponsor). The Trust at the direction of the Sponsor shall furnish any
such legend not contained in Exhibit A-1 to the Institutional Trustee in
writing. Each Capital Security shall be dated the date of its authentication.
The terms and provisions of the Securities set forth in Annex I and the forms of
Securities set forth in Exhibits A-1 and A-2 are part of the terms of this
Declaration and to the extent applicable, the Institutional Trustee, the
Delaware Trustee, the Administrators and the Sponsor, by their execution and
delivery of this Declaration, expressly agree to such terms and provisions and
to be bound thereby. Capital Securities will be issued only in blocks having a
stated liquidation amount of not less than $100,000 and multiples of $1,000 in
excess thereof.

            (b)   The Capital Securities sold by the Trust to the initial
purchasers pursuant to the Placement Agreement and the Capital Securities
Purchase Agreement shall be issued in definitive form, registered in the name of
the Holder thereof, without coupons and with the Restricted Securities Legend.

      SECTION 6.4. Mutilated, Destroyed, Lost or Stolen Certificates. If: (a)
any mutilated Certificates should be surrendered to the Registrar, or if the
Registrar shall receive evidence to its satisfaction of the destruction, loss or
theft of any Certificate; and (b) there shall be delivered to the Registrar, the
Administrators and the Institutional Trustee such security or indemnity as may
be required by them to hold each of them harmless; then, in the absence of
notice that such Certificate shall have been acquired by a bona fide purchaser,
an Administrator on behalf of the Trust shall execute (and in the case of a
Capital Security Certificate, the Institutional Trustee shall authenticate) and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like denomination. In connection with
the issuance of any new Certificate under this Section 6.4, the Registrar or the
Administrators may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection therewith. Any
duplicate Certificate issued pursuant to this Section shall constitute
conclusive evidence of an ownership interest in the relevant Securities, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

      SECTION 6.5. Temporary Securities. Until definitive Securities are ready
for delivery, the Administrators may prepare and, in the case of the Capital
Securities, the Institutional Trustee shall authenticate, temporary Securities.
Temporary Securities shall be substantially in form of definitive Securities but
may have variations that the Administrators consider appropriate for temporary
Securities. Without unreasonable delay, the Administrators shall prepare and, in
the case of the Capital Securities, the Institutional Trustee shall authenticate
definitive Securities in exchange for temporary Securities.

      SECTION 6.6. Cancellation. The Administrators at any time may deliver
Securities to the Registrar for cancellation. The Registrar shall forward to the
Institutional Trustee any Securities surrendered to it for registration of
transfer, redemption or payment. The Institutional Trustee shall promptly cancel
all Securities surrendered for registration of transfer, payment, replacement or
cancellation and shall dispose of such canceled Securities in accordance with
its standard procedures or otherwise as the Administrators direct. The
Administrators may not issue new Securities to replace Securities that have been
paid or that have been delivered to the Institutional Trustee for cancellation.

      SECTION 6.7. Rights of Holders; Waivers of Past Defaults.

            (a)   The legal title to the Trust Property is vested exclusively in
the Institutional Trustee (in its capacity as such) in accordance with Section
2.5, and the Holders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Securities and they shall have no right to call for any partition or division of
property, profits or rights of the Trust except as described below. The
Securities shall be personal property giving only the rights specifically set
forth therein and in this Declaration. The Securities shall have no, and the
issuance of the Securities shall not be subject to,

                                      -31-
<PAGE>

preemptive or other similar rights and when issued and delivered to Holders
against payment of the purchase price therefor, the Securities will be fully
paid and nonassessable by the Trust.

            (b)   For so long as any Capital Securities remain outstanding, if,
upon an Indenture Event of Default under Section 5.01(c) of the Indenture, the
Debenture Trustee fails or the holders of not less than 25% in principal amount
of the outstanding Debentures fail to declare the principal of all of the
Debentures to be immediately due and payable, the Holders of not less than a
Majority in liquidation amount of the Capital Securities then outstanding shall
have the right to make such declaration by a notice in writing to the
Institutional Trustee, the Sponsor and the Debenture Trustee.

            (c)   At any time after a declaration of acceleration of maturity of
the Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as provided in the
Indenture, if the Institutional Trustee, subject to the provisions hereof, fails
to annul any such declaration and waive such default, the Holders of not less
than a Majority in liquidation amount of the Capital Securities, by written
notice to the Institutional Trustee, the Sponsor and the Debenture Trustee, may
rescind and annul such declaration and its consequences if:

                  (i)   the Sponsor has paid or deposited with the Debenture
            Trustee a sum sufficient to pay

                        (A) all overdue installments of interest on all of the
                  Debentures;

                        (B) any accrued Deferred Interest on all of the
                  Debentures;

                        (C) all payments on any Debentures that have become due
                  otherwise than by such declaration of acceleration and
                  interest and Deferred Interest thereon at the rate borne by
                  the Debentures; and

                        (D) all sums paid or advanced by the Debenture Trustee
                  under the Indenture and the reasonable compensation,
                  documented expenses, disbursements and advances of the
                  Debenture Trustee and the Institutional Trustee, their agents
                  and counsel; and

                  (ii)  all Events of Default with respect to the Debentures,
            other than the non-payment of the principal of or premium, if any,
            on the Debentures that has become due solely by such acceleration,
            have been cured or waived as provided in Section 5.07 of the
            Indenture.

            (d)   The Holders of not less than a Majority in liquidation amount
of the Capital Securities may, on behalf of the Holders of all the Capital
Securities, waive any past default or Event of Default, except a default or
Event of Default in the payment of principal or interest (unless such default or
Event of Default has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Debenture Trustee) or a default or Event of Default in
respect of a covenant or provision that under the Indenture cannot be modified
or amended without the consent of the

                                      -32-
<PAGE>

holder of each outstanding Debenture. No such rescission shall affect any
subsequent default or impair any right consequent thereon.

            (e)   Upon receipt by the Institutional Trustee of written notice
declaring such an acceleration, or rescission and annulment thereof, by Holders
of any part of the Capital Securities, a record date shall be established for
determining Holders of outstanding Capital Securities entitled to join in such
notice, which record date shall be at the close of business on the day the
Institutional Trustee receives such notice. The Holders on such record date, or
their duly designated proxies, and only such Persons, shall be entitled to join
in such notice, whether or not such Holders remain Holders after such record
date; provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day that is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice that has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 6.7.

            (f)   Except as otherwise provided in this Section 6.7, the Holders
of not less than a Majority in liquidation amount of the Capital Securities may,
on behalf of the Holders of all the Capital Securities, waive any past default
or Event of Default and its consequences. Upon such waiver, any such default or
Event of Default shall cease to exist, and any default or Event of Default
arising therefrom shall be deemed to have been cured, for every purpose of this
Declaration, but no such waiver shall extend to any subsequent or other default
or Event of Default or impair any right consequent thereon.

                      DISSOLUTION AND TERMINATION OF TRUST

      SECTION 7.1. Dissolution and Termination of Trust.

            (a)   The Trust shall dissolve on the first to occur of

                  (i)   unless earlier dissolved, on March 29, 2040, the
            expiration of the term of the Trust;

                  (ii)  a Bankruptcy Event with respect to the Sponsor, the
            Trust or the Debenture Issuer;

                  (iii) (other than in connection with a merger, consolidation
            or similar transaction not prohibited by the Indenture, this
            Declaration or the Guarantee, as the case may be) the filing of a
            certificate of dissolution or its equivalent with respect to the
            Sponsor or upon the revocation of the charter of the Sponsor and the
            expiration of 90 days after the date of revocation without a

            of the Securities, upon exercise of the right of the Holders of all
            of the outstanding Common Securities to dissolve the Trust as
            provided in Annex I hereto;

                  (v)   the entry of a decree of judicial dissolution of any
            Holder of the Common Securities, the Sponsor, the Trust or the
            Debenture Issuer;

                  (vi)  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; or

                  (vii) before the issuance of any Securities, with the consent
            of all of the Trustees and the Sponsor.

            (b)   As soon as is practicable after the occurrence of an event
referred to in Section 7.1(a), and after satisfaction of liabilities to
creditors of the Trust as required by applicable law, including Section 3808 of
the Statutory Trust Act, and subject to the terms set forth in Annex I, the
Delaware Trustee, when notified in writing of the completion of the winding up
of the Trust in accordance with the Statutory Trust Act, shall terminate the
Trust by filing, at the expense of the Sponsor, a certificate of cancellation
with the Secretary of State of the State of Delaware.

            (c)   The provisions of Section 2.9 and Article IX shall survive the
termination of the Trust.

                                  ARTICLE VIII
                              TRANSFER OF INTERESTS

      SECTION 8.1. General.

            (a)   Subject to Section 6.4 and Section 8.1(c), when Capital
Securities are presented to the Registrar with a request to register a transfer
or to exchange them for an equal number of Capital Securities represented by
different Certificates, the Registrar shall register the transfer or make the
exchange if the requirements provided for herein for such transactions are met.
To permit registrations of transfers and exchanges, the Trust shall issue and
the Institutional Trustee shall authenticate Capital Securities at the
Registrar's request.

            (b)   Upon issuance of the Common Securities, the Sponsor shall
acquire and retain beneficial and record ownership of the Common Securities and,
for so long as the Securities remain outstanding, the Sponsor shall maintain
100% ownership of the Common Securities; provided, however, that any permitted
successor of the Sponsor under the Indenture that is a U.S. Person may succeed
to the Sponsor's ownership of the Common Securities.

            (c)   Capital Securities may only be transferred, in whole or in
part, in accordance with the terms and conditions set forth in this Declaration
and in the terms of the Capital Securities. To the fullest extent permitted by
applicable law, any transfer or purported transfer of any Security not made in
accordance with this Declaration shall be null and void and will be deemed to be
of no legal effect whatsoever and any such transferee shall be deemed not

                                      -34-
<PAGE>

to be the holder of such Capital Securities for any purpose, including but not
limited to the receipt of Distributions on such Capital Securities, and such
transferee shall be deemed to have no interest whatsoever in such Capital
Securities.

            (d)   The Registrar shall provide for the registration of Securities
and of transfers of Securities, which will be effected without charge but only
upon payment (with such indemnity as the Registrar may require) in respect of
any tax or other governmental charges that may be imposed in relation to it.
Upon surrender for registration of transfer of any Securities, the Registrar
shall cause one or more new Securities to be issued in the name of the
designated transferee or transferees. Any Security issued upon any registration
of transfer or exchange pursuant to the terms of this Declaration shall evidence
the same Security and shall be entitled to the same benefits under this
Declaration as the Security surrendered upon such registration of transfer or
exchange. Every Security surrendered for registration of transfer shall be
accompanied by a written instrument of transfer in form satisfactory to the
Registrar duly executed by the Holder or such Holder's attorney duly authorized
in writing. Each Security surrendered for registration of transfer shall be
canceled by the Institutional Trustee pursuant to Section 6.6. A transferee of a
Security shall be entitled to the rights and subject to the obligations of a
Holder hereunder upon the receipt by such transferee of a Security. By
acceptance of a Security, each transferee shall be deemed to have agreed to be
bound by this Declaration.

            (e)   Neither the Trust nor the Registrar shall be required (i) to
issue, register the transfer of, or exchange any Securities during a period
beginning at the opening of business 15 days before the day of any selection of
Securities for redemption and ending at the close of business on the earliest
date on which the relevant notice of redemption is deemed to have been given to
all Holders of the Securities to be redeemed, or (ii) to register the transfer
or exchange of any Security so selected for redemption in whole or in part,
except the unredeemed portion of any Security being redeemed in part.

      SECTION 8.2. Transfer Procedures and Restrictions.

            (a)   The Capital Securities shall bear the Restricted Securities
Legend (as defined below), which shall not be removed unless there is delivered
to the Trust such satisfactory evidence, which may include an opinion of counsel
reasonably acceptable to the Administrators and the Institutional Trustee, as
may be reasonably required by the Trust or the Institutional Trustee, that
neither the legend nor the restrictions on transfer set forth therein are
required to ensure that transfers thereof comply with the provisions of the
Securities Act or that such Securities are not "restricted" within the meaning
of Rule 144 under the Securities Act. Upon provision of such satisfactory
evidence, the Institutional Trustee, at the written direction of the
Administrators, shall authenticate and deliver Capital Securities that do not
bear the Restricted Securities Legend (other than the legend contemplated by
Section 8.2(d)).

            (b)   When Capital Securities are presented to the Registrar (x) to
register the transfer of such Capital Securities, or (y) to exchange such
Capital Securities for an equal number of Capital Securities represented by
different Certificates, the Registrar shall register the transfer or make the
exchange as requested if its reasonable requirements for such transaction are
met; provided, however, that the Capital Securities surrendered for registration
of transfer or

                                      -35-
<PAGE>

exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form reasonably satisfactory to the Administrators, the
Institutional Trustee and the Registrar, duly executed by the Holder thereof or
his attorney duly authorized in writing.

            (c)   Except as permitted by Section 8.2(a), each Capital Security
shall bear a legend (the "Restricted Securities Legend") in substantially the
following form:

      THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS

CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM IN
ACCORDANCE WITH THE AMENDED AND RESTATED DECLARATION OF TRUST, A COPY OF WHICH
MAY BE OBTAINED FROM THE DEBENTURE ISSUER OR THE TRUST. THE HOLDER OF THIS
SECURITY BY ITS ACCEPTANCE HEREOF AGREES THAT IT WILL COMPLY WITH THE FOREGOING
RESTRICTIONS.

      THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES, REPRESENTS
AND WARRANTS THAT IT WILL NOT ENGAGE IN HEDGING TRANSACTIONS INVOLVING THIS
SECURITY UNLESS SUCH TRANSACTIONS ARE IN COMPLIANCE WITH THE SECURITIES ACT.

ON BEHALF OF AN EMPLOYEE BENEFIT PLAN OR PLAN, OR ANY OTHER PERSON OR ENTITY
USING THE ASSETS OF ANY EMPLOYEE BENEFIT PLAN OR PLAN TO FINANCE SUCH PURCHASE,
OR (ii) SUCH PURCHASE WILL NOT RESULT IN A PROHIBITED TRANSACTION UNDER SECTION
406 OF ERISA OR SECTION 4975 OF THE CODE FOR WHICH THERE IS NO APPLICABLE
STATUTORY OR ADMINISTRATIVE EXEMPTION.

      IN CONNECTION WITH ANY TRANSFER, THE HOLDER OF THE CERTIFICATE WILL
DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER
INFORMATION AS MAY BE REQUIRED BY THE AMENDED AND RESTATED DECLARATION OF TRUST
TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

      THIS SECURITY WILL BE ISSUED AND MAY BE TRANSFERRED ONLY IN BLOCKS HAVING
A LIQUIDATION AMOUNT OF NOT LESS THAN $100,000 AND MULTIPLES OF $1,000 IN EXCESS
THEREOF. ANY ATTEMPTED TRANSFER OF THIS SECURITY IN A BLOCK HAVING A LIQUIDATION

HAVE NO INTEREST WHATSOEVER IN THIS SECURITY.

            (d)   Capital Securities may only be transferred in minimum blocks
of $100,000 aggregate liquidation amount (100 Capital Securities) and multiples
of $1,000 in excess thereof. Any attempted transfer of Capital Securities in a
block having an aggregate liquidation amount of less than $100,000 shall be
deemed to be void and of no legal effect whatsoever. Any such

                                      -37-
<PAGE>

purported transferee shall be deemed not to be a Holder of such Capital
Securities for any purpose, including, but not limited to, the receipt of
Distributions on such Capital Securities, and such purported transferee shall be
deemed to have no interest whatsoever in such Capital Securities.

            (e)   Each party hereto understands and hereby agrees that the
Initial Purchaser is intended solely to be an interim holder of the Capital
Securities and is purchasing such securities to facilitate consummation of the
transactions contemplated herein and in the documents ancillary hereto.
Notwithstanding any provision in this Declaration to the contrary, the Initial
Purchaser shall have the right upon notice (a "Transfer Notice") to the
Institutional Trustee and the Sponsor to transfer title in and to the Capital
Securities; provided the Initial Purchaser shall take reasonable steps to ensure
that such transfer is exempt from registration under the Securities Act of 1933,
as amended, and rules promulgated thereunder. Any Transfer Notice delivered to
the Institutional Trustee and Sponsor pursuant to the preceding sentence shall
indicate the aggregate liquidation amount of Capital Securities being
transferred, the name and address of the transferee thereof (the "Transferee")
and the date of such transfer. Notwithstanding any provision in this Declaration
to the contrary, the transfer by the Initial Purchaser of title in and to the
Capital Securities pursuant to a Transfer Notice shall not be subject to any
requirement relating to Opinions of Counsel, Certificates of Transfer or any
other Opinion or Certificate applicable to transfers hereunder and relating to
Capital Securities.

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

            capital contributions (or any return thereon) of the Holders of the
            Securities which shall be made solely from assets of the Trust; and

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

the debts and obligations of the Trust (other than with respect to the
Securities) to the extent not satisfied out of the Trust's assets.

            (c)   Except to the extent provided in Section 9.1(b), and pursuant
to Section 3803(a) of the Statutory Trust Act, the Holders of the Securities
shall be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware, except as otherwise specifically set
forth herein.

      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 Declaration or by law,
except that an Indemnified Person (other than an Administrator) shall be liable
for any such loss, damage or claim incurred by reason of such Indemnified
Person's negligence or willful misconduct or bad faith with respect to such acts
or omissions and except that an Administrator shall be liable for any such loss,
damage or claim incurred by reason of such Administrator's gross negligence or
willful misconduct or bad faith with respect to such acts or omissions.

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

      SECTION 9.3. Fiduciary Duty.

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

            (b)   Whenever in this Declaration 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

                                      -39-
<PAGE>

            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 Declaration or by applicable law.

      SECTION 9.4. Indemnification.

            (a)   (i)   The Sponsor shall indemnify, to the fullest extent
            permitted by law, any 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 such Person is or was
            an Indemnified Person against expenses (including attorneys' fees
            and expenses), judgments, fines and amounts paid in settlement
            actually and reasonably incurred by such Person in connection with
            such action, suit or proceeding if such Person acted in good faith
            and in a manner such Person 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
            such 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 Indemnified Person did not act in good
            faith and in a manner which such Person 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 such conduct was unlawful.

                  (ii)  The Sponsor shall indemnify, to the fullest extent
            permitted by law, any 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 such Person is or
            was an Indemnified Person against expenses (including attorneys'
            fees and expenses) actually and reasonably incurred by such Person
            in connection with the defense or settlement of such action or suit
            if such Person acted in good faith and in a manner such Person
            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 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.

                                      -40-
<PAGE>
                  (iii) To the extent that an 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, such Person shall be
            indemnified, to the fullest extent permitted by law, against
            expenses (including attorneys' fees and expenses) actually and
            reasonably incurred by such Person in connection therewith.

                  (iv)  Any indemnification of an Administrator under paragraphs
            (i) and (ii) of this Section 9.4(a) (unless ordered by a court)
            shall be made by the Sponsor only as authorized in the specific case
            upon a determination that indemnification of the Indemnified Person
            is proper in the circumstances because such Person has met the
            applicable standard of conduct set forth in paragraphs (i) and (ii).
            Such determination shall be made (A) by the Administrators by a
            majority vote of a Quorum consisting of such Administrators who were
            not parties to such action, suit or proceeding, (B) if such a Quorum
            is not obtainable, or, even if obtainable, if a Quorum of
            disinterested Administrators so directs, by independent legal
            counsel in a written opinion, or (C) by the Common Security Holder
            of the Trust.

                  (v)   To the fullest extent permitted by law, expenses
            (including attorneys' fees and expenses) incurred by an 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 Sponsor in
            advance of the final disposition of such action, suit or proceeding
            upon receipt of an undertaking by or on behalf of such Indemnified
            Person to repay such amount if it shall ultimately be determined
            that such Person is not entitled to be indemnified by the Sponsor as
            authorized in this Section 9.4(a). Notwithstanding the foregoing, no
            advance shall be made by the Sponsor if a determination is
            reasonably and promptly made (1) in the case of a Company
            Indemnified Person (A) by the Administrators by a majority vote of a
            Quorum of disinterested Administrators, (B) if such a Quorum is not
            obtainable, or, even if obtainable, if a Quorum of disinterested
            Administrators so directs, by independent legal counsel in a written
            opinion or (C) by the Common Security Holder of the Trust, that,
            based upon the facts known to the Administrators, counsel or the
            Common Security Holder at the time such determination is made, such
            Indemnified Person acted in bad faith or in a manner that such
            Person either believed to be opposed to or did not believe to be in
            the best interests of the Trust, or, with respect to any criminal
            proceeding, that such Indemnified Person believed or had reasonable
            cause to believe such conduct was unlawful, or (2) in the case of a
            Fiduciary Indemnified Person, by independent legal counsel in a
            written opinion that, based upon the facts known to the counsel at
            the time such determination is made, such Indemnified Person acted
            in bad faith or in a manner that such Indemnified Person either
            believed to be opposed to or did not believe to be in the best
            interests of the Trust, or, with respect to any criminal proceeding,
            that such Indemnified Person believed or had reasonable cause to
            believe such conduct was unlawful. In no event shall any advance be
            made (i) to a Company Indemnified

                                      -41-
<PAGE>

            Person in instances where the Administrators, independent legal
            counsel or the Common Security Holder reasonably determine that such
            Person deliberately breached such Person's duty to the Trust or its
            Common or Capital Security Holders or (ii) to a Fiduciary
            Indemnified Person in instances where independent legal counsel
            promptly and reasonably determines in a written opinion that such
            Person deliberately breached such Person's duty to the Trust or its
            Common or Capital Security Holders.

            (b)   The Sponsor shall indemnify, to the fullest extent permitted
by applicable law, each Indemnified Person from and against any and all loss,
damage, liability, tax (other than taxes based on the income of such Indemnified
Person), penalty, expense or claim of any kind or nature whatsoever incurred by
such Indemnified Person arising out of or in connection with or by reason of the
creation, administration or termination of the Trust, or any act or omission of
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 authority
conferred on such Indemnified Person by this Declaration, except that no
Indemnified Person shall be entitled to be indemnified in respect of any loss,
damage, liability, tax, penalty, expense or claim incurred by such Indemnified
Person by reason of negligence, willful misconduct or bad faith with respect to
such acts or omissions.

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

            (d)   The Sponsor or the Trust may purchase and maintain insurance
on behalf of any Person who is or was an Indemnified Person against any
liability asserted against such Person and incurred by such Person in any such
capacity, or arising out of such Person's status as such, whether or not the
Sponsor would have the power to indemnify such Person against such liability
under the provisions of this Section 9.4.

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

                                      -42-
<PAGE>

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

            (g)   The provisions of this Section 9.4 shall survive the
termination of this Declaration or the earlier resignation or removal of the
Institutional Trustee. The obligations of the Sponsor under this Section 9.4 to
compensate and indemnify the Trustees and to pay or reimburse the Trustees for
expenses, disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to that
of the Securities upon all property and funds held or collected by the Trustees
as such, except funds held in trust for the benefit of the holders of particular
Capital Securities, provided, that the Sponsor is the holder of the Common
Securities.

      SECTION 9.5. Outside Businesses. Any Covered Person, the Sponsor, the
Delaware Trustee and the Institutional Trustee (subject to Section 4.3(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 of Securities shall have no rights
by virtue of this Declaration in and to such independent ventures or the income
or profits derived therefrom, and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper. None of any Covered Person, the Sponsor, the Delaware Trustee or the
Institutional Trustee shall be obligated to present any particular investment or
other opportunity to the Trust even if such opportunity is of a character that,
if presented to the Trust, could be taken by the Trust, and any Covered Person,
the Sponsor, the Delaware Trustee and the Institutional Trustee shall have the
right to take for its own account (individually or as a partner or fiduciary) or
to recommend to others any such particular investment or other opportunity. Any
Covered Person, the Delaware Trustee and the Institutional Trustee may engage or
be interested in any financial or other transaction with the Sponsor or any
Affiliate of the Sponsor, or may act as depositary for, trustee or agent for, or
act on any committee or body of holders of, securities or other obligations of
the Sponsor or its Affiliates.

      SECTION 9.6. Compensation; Fee.

            (a)   Subject to the provisions set forth in the Fee Agreement
between the Institutional Trustee, Cohen Bros. & Company and the Company of even
date herewith, the Sponsor agrees:

                  (i)   to pay to the Trustees from time to time such
            compensation for all services rendered by them hereunder as the
            parties shall agree in writing from time to time (which compensation
            shall not be limited by any provision of law in regard to the
            compensation of a trustee of an express trust); and

                  (ii)  except as otherwise expressly provided herein, to
            reimburse the Trustees upon request for all reasonable, documented
            expenses, disbursements and advances incurred or made by the
            Trustees in accordance with any provision of this Declaration
            (including the reasonable compensation and the expenses and

                                      -43-
<PAGE>

            disbursements of their respective agents and counsel), except any
            such expense, disbursement or advance attributable to their
            negligence or willful misconduct.

            (b)   The provisions of this Section 9.6 shall survive the
dissolution of the Trust and the termination of this Declaration and the removal
or resignation of any Trustee.

                                   ARTICLE X

      SECTION 10.1. Fiscal Year. The fiscal year (the "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
Administrators shall keep, or cause to be kept at the principal office of the
Trust in the United States, as defined for purposes of Treasury Regulations
Section 301.7701-7, 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.

            (b)   The Administrators shall either (i) cause each Form 10-K and
Form 10-Q prepared by the Sponsor and filed with the Commission in accordance
with the Exchange Act to be delivered to each Holder of Securities, within 90
days after the filing of each Form 10-K and within 30 days after the filing of
each Form 10-Q or (ii) cause to be prepared at the principal office of the Trust
in the United States, as defined for purposes of Treasury Regulations Section
301.7701-7, and delivered to each of the Holders of Securities, within 90 days
after the end of each Fiscal Year of the Trust, annual financial statements of
the Trust, including a balance sheet of the Trust as of the end of such Fiscal
Year, and the related statements of income or loss.

            (c)   The Administrators shall cause to be duly prepared and
delivered to each of the Holders of Securities Form 1099 or such other 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 Administrators
shall endeavor to deliver all such statements within 30 days after the end of
each Fiscal Year of the Trust.

            (d)   The Administrators shall cause to be duly prepared in the
United States, as defined for purposes of Treasury Regulations Section
301.7701-7, and filed an annual United States federal income tax return on a
Form 1041 or such other form required by United States federal income tax law,
and any other annual income tax returns required to be filed by the
Administrators on behalf of the Trust with any state or local taxing authority.

      SECTION 10.3. Banking. The Trust shall maintain one or more bank accounts
in the United States, as defined for purposes of Treasury Regulations Section
301.7701-7, 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
Institutional Trustee shall be made directly to the Property Account and

                                      -44-
<PAGE>

no other funds of the Trust shall be deposited in the Property Account. The sole
signatories for such accounts (including the Property Account) shall be
designated by the Institutional Trustee.

      SECTION 10.4. Withholding. The Institutional Trustee or any Paying Agent
and the Administrators shall comply with all withholding requirements under
United States federal, state and local law. As a condition to the payment of any
principal of or interest on any Debt Security without the imposition of
withholding tax, the Institutional Trustee or any Paying Agent shall require the
previous delivery of properly completed and signed applicable U.S. federal
income tax certifications (generally, an Internal Revenue Service Form W-9 (or
applicable successor form) in the case of a person that is a "United States
person" within the meaning of Section 7701(a)(30) of the Code or an Internal
Revenue Service Form W-8 (or applicable successor form) in the case of a person
that is not a "United States person" within the meaning of Section 7701(a)(30)
of the Code) and any other certification acceptable to it to enable the
Institutional Trustee or any Paying Agent and the Trustee to determine their
respective duties and liabilities with respect to any taxes or other charges
that they may be required to pay, deduct or withhold in respect of such Debt
Security or the holder of such Debt Security under any present or future law or
regulation of the United States or any political subdivision thereof or taxing
authority therein or to comply with any reporting or other requirements under
any such law or regulation. The Administrators 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 Institutional Trustee or any
Paying Agent 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 to the Holder in the amount of the
withholding. In the event of any claimed overwithholding, Holders shall be
limited to an action against the applicable jurisdiction. If the amount required
to be withheld was not withheld from actual Distributions made, the
Institutional Trustee or any Paying Agent may reduce subsequent Distributions by
the amount of such withholding.

                                   ARTICLE XI

applicable terms of the Securities, this Declaration may only be amended by a
written instrument approved and executed by:

                  (i)   the Institutional Trustee,

                  (ii)  if the amendment affects the rights, powers, duties,

            (b)   Notwithstanding any other provision of this Article XI, no
amendment shall be made, and any such purported amendment shall be void and
ineffective:

                  (i)   unless the Institutional Trustee shall have first
            received

                        (A) an Officers' Certificate from each of the Trust and
                  the Sponsor that such amendment is permitted by, and conforms

                  conforms to, the terms of this Declaration (including the
                  terms of the Securities) and that all conditions precedent to
                  the execution and delivery of such amendment have been
                  satisfied; or

                  (ii)  if the result of such amendment would be to

                  purposes of United States federal income taxation as a grantor
                  trust;

                  Company required to be registered under the Investment Company
                  Act; or

                        (D) cause the Debenture Issuer to be unable to treat an
                  amount equal to the Liquidation Amount of the Capital

                  the Debenture Issuer were subject to such guidelines of
                  policies) or of (y) any other regulatory authority having
                  jurisdiction over the Debenture Issuer.

            which amendment does not have a material adverse effect on the
            right, preferences or privileges of the Holders of Securities;

provided, however, that no such modification, elimination or addition referred
to in clauses (i), (ii), (iii) or (iv) shall adversely affect the powers,
preferences or rights of Holders of Capital Securities.

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

            (a)   Meetings of the Holders of any class of Securities may be
called at any time by the Administrators (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Declaration, the terms of
the Securities or the rules of any stock exchange on which the Capital
Securities are listed or admitted for trading, if any. The Administrators shall
call a meeting of the Holders of such class if directed to do so by the Holders
of not less than 10% in liquidation amount of such class of Securities. Such
direction shall be given by delivering to the Administrators one or more notices
in a writing stating that the signing Holders of the Securities wish to call a
meeting and indicating the general or specific purpose for which the meeting is
to be called. Any Holders of the Securities calling a meeting shall specify in
writing the Certificates held by the Holders of the Securities exercising the
right to call a meeting and only those

                                      -47-
<PAGE>

Securities represented by such Certificates shall be counted for purposes of
determining whether the required percentage set forth in the second sentence of
this paragraph has been met.

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

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

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

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

                                      -48-
<PAGE>

            provided, however, that each meeting shall be conducted in the
            United States (as that term is defined in Treasury Regulations
            Section 301.7701-7).

an aggregate stated liquidation amount with respect to the assets of the Trust
of One Hundred Fifty Five Thousand Dollars ($155,000) and a stated liquidation
amount with respect to the assets of the Trust of $1,000 per Common Security.

      2.    Distributions.

      (a)   Distributions payable on each Security will be payable at a variable
per annum rate of interest, reset quarterly, equal to LIBOR, as determined on
the LIBOR Determination Date for such Distribution Payment Period, plus 1.95%
(the "Coupon Rate") of the stated liquidation amount of $1,000 per Security
(provided, however, that the Coupon Rate for any Distribution Payment Period may
not exceed the highest rate permitted by New York law, as the same may be
modified by United States law of general applicability), such Coupon Rate being
the rate of interest payable on the Debentures to be held by the Institutional
Trustee. Except as set forth below in respect of an Extension Period,
Distributions in arrears for more than one quarterly period will bear interest
thereon compounded quarterly at the applicable Coupon Rate for each such
quarterly period (to the extent permitted by applicable law). The term
"Distributions" as used herein includes cash distributions, any such compounded
distributions and any Additional Interest payable on the Debentures unless
otherwise stated. A Distribution is payable only to the extent that payments are
made in respect of the Debentures held by the

                                     A-I-1
<PAGE>

Institutional Trustee and to the extent the Institutional Trustee has funds
legally available in the Property Account therefor. The amount of Distributions
payable for any Distribution Payment Period will be computed for any full
quarterly Distribution Payment Period on the basis of a 360-day year and the
actual number of days elapsed in the relevant Distribution period; provided,
however, that upon the occurrence of a Special Event redemption pursuant to
paragraph 4(a) below the amounts payable pursuant to this Declaration shall be
calculated as set forth in the definition of Special Redemption Price.

      (b)   LIBOR shall be determined by the Calculation Agent in accordance
with the following provisions:

                  (1)   On the second LIBOR Business Day (provided, that on such
            day commercial banks are open for business (including dealings in
            foreign currency deposits) in London (a "LIBOR Banking Day"), and
            otherwise the next preceding LIBOR Business Day that is also a LIBOR
            Banking Day) prior to March 15, June 15, September 15 and December
            15 (or, with respect to the first Distribution Payment Period, on
            March 25, 2005), (each such day, a "LIBOR Determination Date") for
            such Distribution Payment Period), the Calculation Agent shall
            obtain the rate for three-month U.S. Dollar deposits in Europe,
            which appears on Telerate Page 3750 (as defined in the International
            Swaps and Derivatives Association, Inc. 2000 Interest Rate and
            Currency Exchange Definitions) or such other page as may replace
            such Telerate Page 3750 on the Moneyline Telerate, Inc. service (or
            such other service or services as may be nominated by the British
            Banker's Association as the information vendor for the purpose of
            displaying London interbank offered rates for U.S. dollar deposits),
            as of 11:00 a.m. (London time) on such LIBOR Determination Date, and
            the rate so obtained shall be LIBOR for such Distribution Payment
            Period. "LIBOR Business Day" means any day that is not a Saturday,
            Sunday or other day on which commercial banking institutions in The
            City of New York or Wilmington, Delaware are authorized or obligated
            by law or executive order to be closed. If such rate is superseded
            on Telerate Page 3750 by a corrected rate before 12:00 noon (London
            time) on the same LIBOR Determination Date, the corrected rate as so
            substituted will be the applicable LIBOR for that Distribution
            Payment Period.

                  (2)   If, on any LIBOR Determination Date, such rate does not
            appear on Telerate Page 3750 or such other page as may replace such
            Telerate Page 3750 on the Moneyline Telerate, Inc. service (or such
            other service or services as may be nominated by the British
            Banker's Association as the information vendor for the purpose of
            displaying London interbank offered rates for U.S. dollar deposits),
            the Calculation Agent shall determine the arithmetic mean of the
            offered quotations of the Reference Banks (as defined below) to
            leading banks in the London Interbank market for three-month U.S.
            Dollar deposits in Europe (in an amount determined by the
            Calculation Agent) by reference to requests for quotations as of
            approximately 11:00 a.m. (London time) on the LIBOR Determination
            Date made by the Calculation Agent to the Reference Banks. If, on
            any LIBOR Determination Date, at least two of the Reference Banks
            provide such quotations, LIBOR shall equal the arithmetic mean of
            such quotations. If, on any

                                     A-I-2
<PAGE>

            LIBOR Determination Date, only one or none of the Reference Banks
            provide such a quotation, LIBOR shall be deemed to be the arithmetic
            mean of the offered quotations that at least two leading banks in
            the City of New York (as selected by the Calculation Agent) are
            quoting on the relevant LIBOR Determination Date for three-month
            U.S. Dollar deposits in Europe at approximately 11:00 a.m. (London
            time) (in an amount determined by the Calculation Agent). As used
            herein, "Reference Banks" means four major banks in the London
            Interbank market selected by the Calculation Agent.

                  (3)   If the Calculation Agent is required but is unable to
            determine a rate in accordance with at least one of the procedures
            provided above, LIBOR for the applicable Distribution Payment Period
            shall be LIBOR in effect for the immediately preceding Distribution
            Payment Period.

      (c)   All percentages resulting from any calculations on the Securities
will be rounded, if necessary, to the nearest one hundred-thousandth of a
percentage point, with five one-millionths of a percentage point rounded upward
(e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and
all dollar amounts used in or resulting from such calculation will be rounded to
the nearest cent (with one-half cent being rounded upward).

      (d)   On each LIBOR Determination Date, the Calculation Agent shall
notify, in writing, the Sponsor and the Paying Agent of the applicable Coupon
Rate in effect for the related Distribution Payment Period. The Calculation
Agent shall, upon the request of the Holder of any Securities, provide the
Coupon Rate then in effect. All calculations made by the Calculation Agent in
the absence of manifest error shall be conclusive for all purposes and binding
on the Sponsor and the Holders of the Securities. The Paying Agent shall be
entitled to rely on information received from the Calculation Agent or the
Sponsor as to the Coupon Rate. The Sponsor shall, from time to time, provide any
necessary information to the Paying Agent relating to any original issue
discount and interest on the Securities that is included in any payment and
reportable for taxable income calculation purposes.

      (e)   Distributions on the Securities will be cumulative, will accrue from
the date of original issuance, and will be payable, subject to extension of
Distribution payment periods as described herein, quarterly in arrears on March
15, June 15, September 15 and December 15 of each year, commencing June 15, 2005
(each, a "Distribution Payment Date"). Subject to prior submission of Notice (as
defined in the Indenture), the Debenture Issuer has the right under the
Indenture to defer payments of interest on the Debentures by extending the
interest distribution period for up to 20 consecutive quarterly periods (each,
an "Extension Period") at any time and from time to time on the Debentures,
subject to the conditions described below, during which Extension Period no
interest shall be due and payable (except any Additional Interest that may be
due and payable). During any Extension Period, interest will continue to accrue
on the Debentures, and interest on such accrued interest (such accrued interest
and interest thereon referred to herein as "Deferred Interest") will accrue at
an annual rate equal to the Coupon Rate in effect for each such Extension
Period, compounded quarterly from the date such Deferred Interest would have
been payable were it not for the Extension Period, to the extent permitted by
law. No Extension Period may end on a date other than a Distribution Payment
Date. At the end of any such Extension Period, the Debenture Issuer shall pay
all Deferred Interest then accrued

                                     A-I-3
<PAGE>

and unpaid on the Debentures; provided, however, that no Extension Period may
extend beyond the Maturity Date; and provided, further, that, during any such
Extension Period, the Debenture Issuer may not (i) declare or pay any dividends
or distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Debenture Issuer's capital stock or (ii) make any
payment of principal or premium or interest on or repay, repurchase or redeem
any debt securities of the Debenture Issuer that rank pari passu in all respects
with or junior in interest to the Debentures or (iii) make any payment under any
guarantees of the Debenture Issuer that rank in all respects pari passu with or
junior in interest to the Guarantee (other than (a) repurchases, redemptions or
other acquisitions of shares of capital stock of the Debenture Issuer (A) in
connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of one or more employees, officers,
directors or consultants, (B) in connection with a dividend reinvestment or
stockholder stock purchase plan or (C) in connection with the issuance of
capital stock of the Debenture Issuer (or securities convertible into or
exercisable for such capital stock), as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of any exchange, reclassification, combination or conversion of any class
or series of the Debenture Issuer's capital stock (or any capital stock of a
subsidiary of the Debenture Issuer) for any class or series of the Debenture
Issuer's capital stock or of any class or series of the Debenture Issuer's
indebtedness for any class or series of the Debenture Issuer's capital stock,
(c) the purchase of fractional interests in shares of the Debenture Issuer's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (d) any declaration of a
dividend in connection with any stockholder's rights plan, or the issuance of
rights, stock or other property under any stockholder's rights plan, or the
redemption or repurchase of rights pursuant thereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock). Prior to the termination of any Extension Period, the
Debenture Issuer may further extend such period; provided, that such period
together with all such previous and further consecutive extensions thereof shall
not exceed 20 consecutive quarterly periods, or extend beyond the Maturity Date.
Upon the termination of any Extension Period and upon the payment of all
Deferred Interest, the Debenture Issuer may commence a new Extension Period,
subject to the foregoing requirements. No interest or Deferred Interest shall be
due and payable during an Extension Period, except at the end thereof, but
Deferred Interest shall accrue upon each installment of interest that would
otherwise have been due and payable during such Extension Period until such
installment is paid. If Distributions are deferred, the Distributions due shall
be paid on the date that the related Extension Period terminates, or, if such
date is not a Distribution Payment Date, on the immediately following
Distribution Payment Date, to Holders of the Securities as they appear on the
books and records of the Trust on the record date immediately preceding such
date. Distributions on the Securities must be paid on the dates payable (after
giving effect to any Extension Period) to the extent that the Trust has funds
legally available for the payment of such distributions in the Property Account
of the Trust. The Trust's funds available for Distribution to the Holders of the
Securities will be limited to payments received from the Debenture Issuer. The
payment of Distributions out of moneys held by the Trust is guaranteed by the
Guarantor pursuant to the Guarantee.

      (f)   Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Registrar on the relevant
record dates. The relevant

                                     A-I-4
<PAGE>

record dates shall be selected by the Administrators, which dates shall be 15
days before the relevant Distribution Payment Date. Distributions payable on any
Securities that are not punctually paid on any Distribution Payment Date, as a
result of the Debenture Issuer having failed to make a payment under the
Debentures, as the case may be, when due (taking into account any Extension
Period), will cease to be payable to the Person in whose name such Securities
are registered on the relevant record date, and such defaulted Distribution will
instead be payable to the Person in whose name such Securities are registered on
the special record date or other specified date determined in accordance with
the Indenture. Notwithstanding anything to the contrary contained herein, if any
Distribution Payment Date, other than on the Maturity Date, any Redemption Date
or the Special Redemption Date, falls on a day that is not a Business Day, then
any Distributions payable will be paid on, and such Distribution Payment Date
will be moved to, the next succeeding Business Day, and additional Distributions
will accrue for each day that such payment is delayed as a result thereof. If
the Maturity Date, any Redemption Date or the Special Redemption Date falls on a
day that is not a Business Day, then the principal, premium, if any, and/or
Distributions payable on such date will be paid on the next succeeding Business
Day, and no additional Distributions will accrue in respect of such payment made
on such next succeeding Business Day.

      (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 pro rata (as defined herein) among the Holders of the Securities.

      3.    Liquidation Distribution Upon Dissolution. In the event of the
voluntary or involuntary liquidation, dissolution, winding-up or termination of
the Trust (each, a "Liquidation") other than in connection with a redemption of
the Debentures, the Holders of the Securities will be entitled to receive out of
the assets of the Trust available for distribution to Holders of the Securities,
after satisfaction of liabilities to creditors of the Trust (to the extent not
satisfied by the Debenture Issuer), distributions equal to the aggregate of the
stated liquidation amount of $1,000 per Security plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"), unless in connection with such Liquidation, the Debentures in an
aggregate stated principal amount equal to the aggregate stated liquidation
amount of such Securities, with an interest rate equal to the Coupon Rate of,
and bearing accrued and unpaid interest in an amount equal to the accrued and
unpaid Distributions on, and having the same record date as, such Securities,
after paying or making reasonable provision to pay all claims and obligations of
the Trust in accordance with Section 3808(e) of the Statutory Trust Act, shall
be distributed on a Pro Rata basis to the Holders of the Securities in exchange
for such Securities.

      The Sponsor, as the Holder of all of the Common Securities, has the right
at any time to, upon receipt of an opinion of nationally recognized tax counsel
that Holders will not recognize any gain or loss for United States federal
income tax purposes as a result of the distribution Debentures, dissolve the
Trust (including without limitation upon the occurrence of a Tax Event, an
Investment Company Event or a Capital Treatment Event), subject to the receipt
by the Debenture Issuer of prior approval from any regulatory authority having
jurisdiction over the Sponsor that is primarily responsible for regulating the
activities of the Sponsor if such approval is then required under applicable
capital guidelines or policies of such regulatory authority, and, after
satisfaction of liabilities to creditors of the Trust, cause the Debentures to
be distributed to

                                     A-I-5
<PAGE>

the Holders of the Securities on a Pro Rata basis in accordance with the
aggregate stated liquidation amount thereof.

      The Trust shall dissolve on the first to occur of (i) March 29, 2040, the
expiration of the term of the Trust, (ii) a Bankruptcy Event with respect to the
Sponsor, the Trust or the Debenture Issuer, (iii) (other than in connection with
a merger, consolidation or similar transaction not prohibited by the Indenture,
this Declaration or the Guarantee, as the case may be) the filing of a
certificate of dissolution or its equivalent with respect to the Sponsor or upon
the revocation of the charter of the Sponsor and the expiration of 90 days after
the date of revocation without a reinstatement thereof, (iv) the distribution to
the Holders of the Securities of the Debentures, upon exercise of the right of
the Holder of all of the outstanding Common Securities to dissolve the Trust as
described above, (v) the entry of a decree of a judicial dissolution of the
Sponsor or the Trust, or (vi) 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. As soon as
practicable after the dissolution of the Trust and upon completion of the
winding up of the Trust, the Trust shall terminate upon the filing of a
certificate of cancellation with the Secretary of State of the State of
Delaware.

      If a Liquidation of the Trust occurs as described in clause (i), (ii),
(iii) or (v) in the immediately preceding paragraph, the Trust shall be
liquidated by the Institutional Trustee of the Trust as expeditiously as such
Trustee determines to be possible by distributing, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, to the
Holders of the Securities, the Debentures on a Pro Rata basis to the extent not
satisfied by the Debenture Issuer, unless such distribution is determined by the
Institutional Trustee not to be practical, in which event such Holders will 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 to the
extent not satisfied by the Debenture Issuer, an amount equal to the Liquidation
Distribution. An early Liquidation of the Trust pursuant to clause (iv) of the
immediately preceding paragraph shall occur if the Institutional Trustee
determines that such Liquidation is possible by distributing, after satisfaction
of liabilities to creditors of Trust, to the Holders of the Securities on a Pro
Rata basis, the Debentures, and such distribution occurs.

      If, upon any such Liquidation, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on such Capital Securities shall be paid to the Holders of the Securities
on a Pro Rata basis, except that if an Event of Default has occurred and is
continuing, the Capital Securities shall have a preference over the Common
Securities with regard to such distributions.

      Upon any such Liquidation of the Trust involving a distribution of the
Debentures, if at the time of such Liquidation, the Capital Securities were
rated by at least one nationally-recognized statistical rating organization, the
Debenture Issuer will use its reasonable best efforts to obtain from at least
one such or other rating organization a rating for the Debentures.

      After the date for any distribution of the Debentures upon dissolution of
the Trust, (i) the Securities of the Trust will be deemed to be no longer
outstanding, (ii) any certificates representing the Capital Securities will be
deemed to represent undivided beneficial interests in

                                     A-I-6
<PAGE>

such of the Debentures as have an aggregate principal amount equal to the
aggregate stated liquidation amount of, with an interest rate identical to the
distribution rate of, and bearing accrued and unpaid interest equal to accrued
and unpaid distributions on, the Securities until such certificates are
presented to the Debenture Issuer or its agent for transfer or reissuance (and
until such certificates are so surrendered, no payments of interest or principal
shall be made to Holders of Securities in respect of any payments due and
payable under the Debentures) and (iii) all rights of Holders of Securities
under the Capital Securities or the Common Securities, as applicable, shall
cease, except the right of such Holders to receive Debentures upon surrender of
certificates representing such Securities.

      4.    Redemption and Distribution.

      (a)   The Debentures will mature on June 15, 2035. The Debentures may be
redeemed by the Debenture Issuer, in whole or in part, on any March 15, June 15,
September 15 or December 15 on or after June 15, 2010 at the Redemption Price,
upon not less than 30 nor more than 60 days' notice to Holders of such
Debentures. In addition, upon the occurrence and continuation of a Tax Event, an
Investment Company Event or a Capital Treatment Event, the Debentures may be
redeemed by the Debenture Issuer in whole or in part, at any time within 90 days
following the occurrence of such Tax Event, Investment Company Event or Capital
Treatment Event, as the case may be (the "Special Redemption Date"), at the
Special Redemption Price, upon not less than 30 nor more than 60 days' notice to
Holders of the Debentures so long as such Tax Event, Investment Company Event or
Capital Treatment Event, as the case may be, is continuing. In each case, the
right of the Debenture Issuer to redeem the Debentures is subject to the
Debenture Issuer having received prior approval from any regulatory authority
having jurisdiction over the Debenture Issuer, if such approval is then required
under applicable capital guidelines or policies of such regulatory authority.

      "Tax Event" means the receipt by the Debenture Issuer and the Trust of an
opinion of counsel experienced in such matters to the effect that, as a result
of any amendment to or change (including any announced prospective change) in
the laws or any regulations thereunder of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement (including any private letter ruling,
technical advice memorandum, regulatory procedure, notice or announcement) (an
"Administrative Action") or judicial decision interpreting or applying such laws
or regulations, regardless of whether such Administrative Action or judicial
decision is issued to or in connection with a proceeding involving the Debenture
Issuer or the Trust and whether or not subject to review or appeal, which
amendment, clarification, change, Administrative Action or decision is enacted,
promulgated or announced, in each case on or after the date of original issuance
of the Debentures, there is more than an insubstantial risk that: (i) the Trust
is, or will be within 90 days of the date of such opinion, subject to United
States federal income tax with respect to income received or accrued on the
Debentures; (ii) interest payable by the Debenture Issuer on the Debentures is
not, or within 90 days of the date of such opinion, will not be, deductible by
the Debenture Issuer, in whole or in part, for United States federal income tax
purposes; or (iii) the Trust is, or will be within 90 days of the date of such
opinion, subject to more than a de minimis amount of other taxes (including
withholding taxes), duties, assessments or other governmental charges.

                                     A-I-7
<PAGE>

      "Investment Company Event" means the receipt by the Debenture Issuer and
the Trust of an opinion of counsel experienced in such matters to the effect
that, as a result of a change in law or regulation or written change in
interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority, there is more than an
insubstantial risk that the Trust is or, within 90 days of the date of such
opinion will be, considered an "investment company" that is required to be
registered under the Investment Company Act, which change or prospective change
becomes effective or would become effective, as the case may be, on or after the
date of the original issuance of the Debentures.

      "Capital Treatment Event" means, if the Debenture Issuer is organized and
existing under the laws of the United States or any state thereof or the
District of Columbia, the receipt by the Debenture Issuer and the Trust of an
Opinion of Counsel experienced in such matters to the effect that, as a result
of (a) any amendment to, or change in, the laws, rules or regulations of the
United States or any political subdivision thereof or therein, or any rules,
guidelines or policies of any applicable regulatory authority for the Debenture
Issuer or (b) any official or administrative pronouncement or action or decision
interpreting or applying such laws, rules or regulations, which amendment or
change is effective or which pronouncement, action or decision is announced on
or after the date of original issuance of the Debentures, there is more than an
insubstantial risk that, within 90 days of the receipt of such opinion, the
aggregate Liquidation Amount of the Capital Securities will not be eligible to
be treated by the Debenture Issuer as "Tier 1 Capital" (or the then equivalent
thereof) for purposes of the capital adequacy guidelines of the Federal Reserve
(or any successor regulatory authority with jurisdiction over bank or financial
holding companies), as then in effect and applicable to the Debenture Issuer (or
if the Debenture Issuer is not a bank holding company, such guidelines applied
to the Debenture Issuer as if the Debenture Issuer were subject to such
guidelines); provided, however, that the inability of the Debenture Issuer to
treat all or any portion of the aggregate Liquidation Amount of the Capital
Securities as Tier 1 Capital shall not constitute the basis for a Capital
Treatment Event, if such inability results from the Debenture Issuer having
cumulative preferred stock, minority interests in consolidated subsidiaries, or
any other class of security or interest which the Federal Reserve or OTS, as
applicable, may now or hereafter accord Tier 1 Capital treatment in excess of
the amount which may now or hereafter qualify for treatment as Tier 1 Capital
under applicable capital adequacy guidelines; provided further, however, that
the distribution of the Debentures in connection with the liquidation of the
Trust by the Debenture Issuer shall not in and of itself constitute a Capital
Treatment Event unless such liquidation shall have occurred in connection with a
Tax Event or an Investment Company Event.

      "Special Event" means any of a Capital Treatment Event, a Tax Event or an
Investment Company Event.

      "Special Redemption Price" means, with respect to the redemption of any
Debentures following a Special Event, an amount in cash equal to 103.525% of the
principal amount of Debentures to be redeemed prior to June 15, 2006 and
thereafter equal to the percentage of the principal amount of the Debentures
that is specified below for the Special Redemption Date plus, in each case,
unpaid interest accrued thereon to the Special Redemption Date:

      "Redemption Date" means the date fixed for the redemption of Capital
Securities, which shall be any March 15, June 15, September 15 or December 15 on
or after June 15, 2010.

      "Redemption Price" means 100% of the principal amount of the Debentures
being redeemed plus accrued and unpaid interest on such Debentures to the
Redemption Date.

      (b)   Upon the repayment in full at maturity or redemption in whole or in
part of the Debentures (other than following the distribution of the Debentures
to the Holders of the Securities), the proceeds from such repayment or payment
shall concurrently be applied to redeem Pro Rata at the applicable Redemption
Price, Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so repaid or redeemed; provided, however,
that holders of such Securities shall be given not less than 30 nor more than 60
days' notice of such redemption (other than at the scheduled maturity of the
Debentures).

      (c)   If fewer than all the outstanding Securities are to be so redeemed,
the Common Securities and the Capital Securities will be redeemed Pro Rata and
the Capital Securities to be redeemed will be as described in Section 4(e)(ii)
below.

      (d)   The Trust may not redeem fewer than all the outstanding Capital
Securities unless all accrued and unpaid Distributions have been paid on all
Capital Securities for all quarterly Distribution periods terminating on or
before the date of redemption.

      (e)   Redemption or Distribution Procedures.

                  (i)   Notice of any redemption of, or notice of distribution
            of the Debentures in exchange for, the Securities (a
            "Redemption/Distribution Notice") will be given by the Trust by mail
            to each Holder of Securities to be redeemed or exchanged not fewer
            than 30 nor more than 60 days before the date fixed for redemption
            or exchange thereof which, in the case of a redemption, will be the
            date fixed for redemption of the Debentures. For purposes of the
            calculation of the date of redemption or exchange and the dates on
            which notices are given pursuant to this Section 4(e)(i), a
            Redemption/Distribution Notice shall be deemed to be given on the
            day such notice is first mailed by first-class mail, postage
            prepaid, to Holders of such Securities. Each Redemption/Distribution
            Notice shall be addressed to the Holders of such Securities at the
            address of each such Holder appearing on the books and records of
            the Registrar. No defect in the Redemption/Distribution Notice or in
            the mailing thereof with respect to any Holder shall affect the
            validity of the redemption or exchange proceedings with respect to
            any other Holder.

<PAGE>

                  (ii)  In the event that fewer than all the outstanding
            Securities are to be redeemed, the Securities to be redeemed shall
            be redeemed Pro Rata from each Holder of Capital Securities.

                  (iii) If the Securities are to be redeemed and the Trust gives
            a Redemption/Distribution Notice, which notice may only be issued if
            the Debentures are redeemed as set out in this Section 4 (which
            notice will be irrevocable), then, provided, that the Institutional
            Trustee has a sufficient amount of cash in connection with the
            related redemption or maturity of the Debentures, the Institutional
            Trustee will, with respect to Book-Entry Capital Securities, on the
            Redemption Date, irrevocably deposit with the Depositary for such
            Book-Entry Capital Securities, to the extent available therefore,
            funds sufficient to pay the relevant Redemption Price and will give
            such Depositary irrevocable instructions and authority to pay the
            Redemption Price to the Owners of the Capital Securities. With
            respect to Capital Securities that are not Book-Entry Capital
            Securities, the Institutional Trustee will pay, to the extent
            available therefore, the relevant Redemption Price to the Holders of
            such Securities by check mailed to the address of each such Holder
            appearing on the books and records of the Trust on the redemption
            date. If a Redemption/Distribution Notice shall have been given and
            funds deposited as required, then immediately prior to the close of
            business on the date of such deposit, Distributions will cease to
            accrue on the Securities so called for redemption and all rights of
            Holders of such Securities so called for redemption will cease,
            except the right of the Holders of such Securities to receive the
            applicable Redemption Price specified in Section 4(a). If any date
            fixed for redemption of Securities is not a Business Day, then
            payment of any such Redemption Price payable on such date will be
            made on the next succeeding day that is a Business Day except that,
            if such Business Day falls in the next calendar year, such payment
            will be made on the immediately preceding Business Day, in each case
            with the same force and effect as if made on such date fixed for
            redemption. If payment of the Redemption Price in respect of any
            Securities is improperly withheld or refused and not paid either by
            the Trust or by the Debenture Issuer as guarantor pursuant to the
            Guarantee, Distributions on such Securities will continue to accrue
            at the then applicable rate from the original redemption date to the
            actual date of payment, in which case the actual payment date will
            be considered the date fixed for redemption for purposes of
            calculating the Redemption Price. In the event of any redemption of
            the Capital Securities issued by the Trust in part, the Trust shall
            not be required to (i) issue, register the transfer of or exchange
            any Security during a period beginning at the opening of business 15
            days before any selection for redemption of the Capital Securities
            and ending at the close of business on the earliest date on which
            the relevant notice of redemption is deemed to have been given to
            all Holders of the Capital Securities to be so redeemed or (ii)
            register the transfer of or exchange any Capital Securities so
            selected for redemption, in whole or in part, except for the
            unredeemed portion of any Capital Securities being redeemed in part.

<PAGE>

                  (iv)  Redemption/Distribution Notices shall be sent by the
            Trust (A) in respect of the Capital Securities, to the Holders
            thereof, and (B) in respect of the Common Securities, to the Holder
            thereof.

                  (v)   Subject to the foregoing and applicable law (including,
            without limitation, United States federal securities laws), and
            provided, that the acquiror is not the Holder of the Common
            Securities or the obligor under the Indenture, the Sponsor or any of
            its subsidiaries may at anytime and from time to time purchase
            outstanding Capital Securities by tender, in the open market or by
            private agreement.

      5.    Voting Rights - Capital Securities.

      (a)   Except as provided under Sections 5(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Capital Securities will
have no voting rights. The Administrators are required to call a meeting of the
Holders of the Capital Securities if directed to do so by Holders of not less
than 10% in liquidation amount of the Capital Securities.

      (b)   Subject to the requirements of obtaining a tax opinion by the
Institutional Trustee in certain circumstances set forth in the last sentence of
this paragraph, the Holders of a Majority in liquidation amount of the Capital
Securities, voting separately as a class, have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including the right to direct the
Institutional Trustee, as holder of the Debentures, to (i) exercise the remedies
available under the Indenture as the holder of the Debentures, (ii) waive any
past default that is waivable under the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Debentures shall be
due and payable or (iv) consent on behalf of all the Holders of the Capital
Securities to any amendment, modification or termination of the Indenture or the
Debentures where such consent shall be required; provided, however, that, where
a consent or action under the Indenture would require the consent or act of the
holders of greater than a simple majority in principal amount of Debentures (a
"Super Majority") affected thereby, the Institutional Trustee may only give such
consent or take such action at the written direction of the Holders of not less
than the proportion in liquidation amount of the Capital Securities outstanding
which the relevant Super Majority represents of the aggregate principal amount
of the Debentures outstanding. If the Institutional Trustee fails to enforce its
rights under the Debentures after the Holders of a Majority or Super Majority,
as the case may be, in liquidation amount of such Capital Securities have so
directed the Institutional Trustee, to the fullest extent permitted by law, a
Holder of the Capital Securities may institute a legal proceeding directly
against the Debenture Issuer to enforce the Institutional Trustee's rights under
the Debentures without first instituting any legal proceeding against the
Institutional Trustee or any other person or entity. Notwithstanding the
foregoing, if an Event of Default has occurred and is continuing and such event
is attributable to the failure of the Debenture Issuer to pay interest or
premium, if any, on or principal of the Debentures on the date such interest,
premium, if any, on or principal is payable (or in the case of redemption, the
redemption date), then a Holder of record of the Capital Securities may directly
institute a proceeding for enforcement of payment, on or after the respective
due dates specified in the Debentures, to such Holder directly of the principal
of or premium, if any, or interest on the

                                     A-I-11
<PAGE>

Debentures having an aggregate principal amount equal to the aggregate
liquidation amount of the Capital Securities of such Holder. The Institutional
Trustee shall notify all Holders of the Capital Securities of any default
actually known to the Institutional Trustee with respect to the Debentures
unless (x) such default has been cured prior to the giving of such notice or (y)
the Institutional Trustee determines in good faith that the withholding of such
notice is in the interest of the Holders of such Capital Securities, except
where the default relates to the payment of principal of or interest on any of
the Debentures. Such notice shall state that such Indenture Event of Default
also constitutes an Event of Default hereunder. Except with respect to directing
the time, method and place of conducting a proceeding for a remedy, the
Institutional Trustee shall not take any of the actions described in clause (i),
(ii) or (iii) above unless the Institutional Trustee has obtained an opinion of
tax counsel to the effect that, as a result of such action, the Trust will not
be classified as other than a grantor trust for United States federal income tax
purposes.

      In the event the consent of the Institutional Trustee, as the holder of
the Debentures is required under the Indenture with respect to any amendment,
modification or termination of the Indenture, the Institutional Trustee may
request the written direction of the Holders of the Securities with respect to
such amendment, modification or termination and shall vote with respect to such
amendment, modification or termination as directed by a Majority in liquidation
amount of the Securities voting together as a single class; provided, however,
that where a consent under the Indenture would require the consent of a Super
Majority, the Institutional Trustee may only give such consent at the written
direction of the Holders of not less than the proportion in liquidation amount
of such Securities outstanding which the relevant Super Majority represents of
the aggregate principal amount of the Debentures outstanding. The Institutional
Trustee shall not take any such action in accordance with the written directions
of the Holders of the Securities unless the Institutional Trustee has obtained
an opinion of tax counsel to the effect that, as a result of such action, the
Trust will not be classified as other than a grantor trust for United States
federal income tax purposes.

      A waiver of an Indenture Event of Default will constitute a waiver of the
corresponding Event of Default hereunder. Any required approval or direction of
Holders of the Capital Securities may be given at a separate meeting of Holders
of the Capital Securities convened for such purpose, at a meeting of all of the
Holders of the Securities in the Trust or pursuant to written consent. The
Institutional Trustee will cause a notice of any meeting at which Holders of the
Capital Securities are entitled to vote, or of any matter upon which action by
written consent of such Holders is to be taken, to be mailed to each Holder of
record of the Capital Securities. Each such notice will include a statement
setting forth the following information (i) the date of such meeting or the date
by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which written consent is sought and (iii) instructions
for the delivery of proxies or consents. No vote or consent of the Holders of
the Capital Securities will be required for the Trust to redeem and cancel
Capital Securities or to distribute the Debentures in accordance with the
Declaration and the terms of the Securities.

      Notwithstanding that Holders of the Capital Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Capital Securities that are owned by the Sponsor or any Affiliate of the Sponsor
shall not entitle the Holder thereof to vote or consent

                                     A-I-12
<PAGE>

and shall, for purposes of such vote or consent, be treated as if such Capital
Securities were not outstanding.

      In no event will Holders of the Capital Securities have the right to vote
to appoint, remove or replace the Administrators, which voting rights are vested
exclusively in the Sponsor as the Holder of all of the Common Securities of the
Trust. Under certain circumstances as more fully described in the Declaration,
Holders of Capital Securities have the right to vote to appoint, remove or
replace the Institutional Trustee and the Delaware Trustee.

      6.    Voting Rights - Common Securities.

      (a)   Except as provided under Sections 6(b), 6(c) and 7 and as otherwise
required by law and the Declaration, the Common Securities will have no voting
rights.

      (b)   The Holders of the Common Securities are entitled, in accordance
with Article IV of the Declaration, to vote to appoint, remove or replace any
Administrators.

      (c)   Subject to Section 6.7 of the Declaration and only after each Event
of Default (if any) with respect to the Capital Securities has been cured,
waived or otherwise eliminated and subject to the requirements of the second to
last sentence of this paragraph, the Holders of a Majority in liquidation amount
of the Common Securities, voting separately as a class, may direct the time,
method, and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including (i) directing the time,
method, place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee with respect to the Debentures, (ii) waiving any past default and its
consequences that are waivable under the Indenture, or (iii) exercising any
right to rescind or annul a declaration that the principal of all the Debentures
shall be due and payable, provided, however, that, where a consent or action
under the Indenture would require a Super Majority, the Institutional Trustee
may only give such consent or take such action at the written direction of the
Holders of not less than the proportion in liquidation amount of the Common
Securities which the relevant Super Majority represents of the aggregate
principal amount of the Debentures outstanding. Notwithstanding this Section
6(c), the Institutional Trustee shall not revoke any action previously
authorized or approved by a vote or consent of the Holders of the Capital
Securities. Other than with respect to directing the time, method and place of
conducting any proceeding for any remedy available to the Institutional Trustee
or the Debenture Trustee as set forth above, the Institutional Trustee shall not
take any action described in clause (i), (ii) or (iii) above, unless the
Institutional Trustee has obtained an opinion of tax counsel to the effect that
for the purposes of United States federal income tax the Trust will not be
classified as other than a grantor trust on account of such action. If the
Institutional Trustee fails to enforce its rights under the Declaration, to the
fullest extent permitted by law any Holder of the Common Securities may
institute a legal proceeding directly against any Person to enforce the
Institutional Trustee's rights under the Declaration, without first instituting
a legal proceeding against the Institutional Trustee or any other Person.

      Any approval or direction of Holders of the Common Securities may be given
at a separate meeting of Holders of the Common Securities convened for such
purpose, at a meeting

                                     A-I-13
<PAGE>

of all of the Holders of the Securities in the Trust or pursuant to written
consent. The Administrators will cause a notice of any meeting at which Holders
of the Common Securities are entitled to vote, or of any matter upon which
action by written consent of such Holders is to be taken, to be mailed to each
Holder of the Common Securities. Each such notice will include a statement
setting forth (i) the date of such meeting or the date by which such action is
to be taken, (ii) a description of any resolution proposed for adoption at such
meeting on which such Holders are entitled to vote or of such matter upon which
written consent is sought and (iii) instructions for the delivery of proxies or
consents.

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

      7.    Amendments to Declaration and Indenture.

      (a)   In addition to any requirements under Section 11.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
the powers, preferences or special rights of the Securities, whether by way of
amendment to the Declaration or otherwise, or (ii) the Liquidation of the Trust,
other than as described in Section 7.1 of the Declaration, then the Holders of
outstanding Securities, voting together as a single class, will be entitled to
vote on such amendment or proposal and such amendment or proposal shall not be
effective except with the approval of the Holders of not less than a Majority in
liquidation amount of the Securities affected thereby; provided, however, if any
amendment or proposal referred to in clause (i) above would adversely affect
only the Capital Securities or only the Common Securities, then only the
affected class will be entitled to vote on such amendment or proposal and such
amendment or proposal shall not be effective except with the approval of a
Majority in liquidation amount of such class of Securities.

      (b)   In the event the consent of the Institutional Trustee as the holder
of the Debentures is required under the Indenture with respect to any amendment,
modification or termination of the Indenture or the Debentures, the
Institutional Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination and shall
vote with respect to such amendment, modification, or termination as directed by
a Majority in liquidation amount of the Securities voting together as a single
class; provided, however, that where a consent under the Indenture would require
a Super Majority, the Institutional Trustee may only give such consent at the
written direction of the Holders of not less than the proportion in liquidation
amount of the Securities which the relevant Super Majority represents of the
aggregate principal amount of the Debentures outstanding.

      (c)   Notwithstanding the foregoing, no amendment or modification may be
made to the Declaration if such amendment or modification would (i) cause the
Trust to be classified for purposes of United States federal income taxation as
other than a grantor trust, (ii) reduce or otherwise adversely affect the powers
of the Institutional Trustee or (iii) cause the Trust to be deemed an
"investment company" which is required to be registered under the Investment
Company Act.

                                     A-I-14
<PAGE>

      (d)   Notwithstanding any provision of the Declaration, the right of any
Holder of the Capital Securities to receive payment of distributions and other
payments upon redemption or otherwise, on or after their respective due dates,
or to institute a suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder. For the protection and enforcement of the foregoing provision, each and
every Holder of the Capital Securities shall be entitled to such relief as can
be given either at law or equity.

      8.    Pro Rata. A reference in these terms of the Securities to any
payment, distribution or treatment as being "Pro Rata" shall mean pro rata to
each Holder of the Securities according to the aggregate liquidation amount of
the Securities held by the relevant Holder in relation to the aggregate
liquidation amount of all Securities outstanding unless, in relation to a
payment, an Event of Default has occurred and is continuing, in which case any
funds available to make such payment shall be paid first to each Holder of the
Capital Securities Pro Rata according to the aggregate liquidation amount of the
Capital Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Capital Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Capital Securities, to
each Holder of the Common Securities Pro Rata according to the aggregate
liquidation amount of the Common Securities held by the relevant Holder relative
to the aggregate liquidation amount of all Common Securities outstanding.

      9.    Ranking. The Capital Securities rank pari passu with, and payment
thereon shall be made Pro Rata with, the Common Securities except that, where an
Event of Default has occurred and is continuing, the rights of Holders of the
Common Securities to receive payment of Distributions and payments upon
liquidation, redemption and otherwise are subordinated to the rights of the
Holders of the Capital Securities with the result that no payment of any
Distribution on, or Redemption Price or Special Redemption Price of, any Common
Security, and no other payment on account of redemption, liquidation or other
acquisition of Common Securities, shall be made unless payment in full in cash
of all accumulated and unpaid Distributions on all outstanding Capital
Securities for all distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price or Special Redemption Price the full
amount of such Redemption Price or the Special Redemption Price on all
outstanding Capital Securities then called for redemption, shall have been made
or provided for, and all funds immediately available to the Institutional
Trustee shall first be applied to the payment in full in cash of all
Distributions on, or the Redemption Price or the Special Redemption Price of,
the Capital Securities then due and payable.

      10.   Acceptance of Guarantee and Indenture. Each Holder of the Capital
Securities and the Common Securities, by the acceptance of such Securities,
agrees to the provisions of the Guarantee, including the subordination
provisions therein and to the provisions of the Indenture.

      11.   No Preemptive Rights. The Holders of the Securities shall have no,
and the issuance of the Securities is not subject to, preemptive or similar
rights to subscribe for any additional securities.

      12.   Miscellaneous. These terms constitute a part of the Declaration. The
Sponsor will provide a copy of the Declaration, the Guarantee, and the Indenture
to a Holder without charge on written request to the Sponsor at its principal
place of business.

                          [FORM OF REVERSE OF SECURITY]

      Distributions payable on each Capital Security will be payable at a
variable per annum rate of interest, reset quarterly, equal to LIBOR (as defined
in the Declaration) plus 1.95% (the "Coupon Rate") of the stated liquidation
amount of $1,000 per Capital Security (provided, however, that the Coupon Rate
for any Distribution Payment Period may not exceed the highest rate permitted by
New York law, as the same may be modified by United States law of general
applicability), such Coupon Rate being the rate of interest payable on the
Debentures to be held by the Institutional Trustee. Distributions in arrears for
more than one quarterly period will bear interest thereon compounded quarterly
at the then applicable Coupon Rate for each such quarterly period (to the extent
permitted by applicable law). The term "Distributions" as used herein includes
cash distributions, any such compounded distributions and any Additional
Interest payable on the Debentures unless otherwise stated. A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Institutional Trustee and to the extent the Institutional Trustee
has funds legally available in the Property Account therefor. The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year and the actual number of days
elapsed in the relevant Distribution Payment Period.

      Except as otherwise described below, Distributions on the Capital
Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears on March 15, June 15, September 15 and
December 15 of each year, commencing on June 15, 2005 (each, a "Distribution
Payment Date"). Upon submission of Notice, the Debenture Issuer has the right
under the Indenture to defer payments of interest on the Debentures by extending
the interest distribution period for up to 20 consecutive quarterly periods
(each, an "Extension Period") at any time and from time to time on the
Debentures, subject to the conditions described below, during which Extension
Period no interest shall be due and payable (except any Additional Interest that
may be due and payable). During any Extension Period, interest will continue to
accrue on the Debentures, and interest on such accrued interest (such accrued
interest and interest thereon referred to herein as "Deferred Interest") will
accrue at an annual rate equal to the Coupon Rate in effect for each such
Extension Period, compounded quarterly from the date such Deferred Interest
would have been payable were it not for the Extension Period, to the extent
permitted by law. No Extension Period may end on a date other than a
Distribution Payment Date. At the end of any such Extension Period, the
Debenture Issuer shall pay all Deferred Interest then accrued and unpaid on the
Debentures; provided, however, that no Extension Period may extend beyond the
Maturity Date. Prior to the termination of any Extension Period, the Debenture
Issuer may further extend such period; provided, that such period together with
all such previous and further consecutive extensions thereof shall not exceed 20
consecutive quarterly periods, or extend beyond the Maturity Date. Upon the
termination of any Extension Period and upon the payment of all Deferred
Interest, the Debenture Issuer may commence a new Extension Period, subject to
the foregoing requirements. No interest or Deferred Interest (except any
Additional Amounts that may be due and payable) shall be due and payable during
an Extension Period, except at the end thereof, but Deferred Interest shall
accrue upon each installment of interest that would otherwise have been due and
payable during such Extension Period until such installment is paid. If
Distributions are deferred, the Distributions due shall be paid on the date that
the related Extension Period terminates to Holders of the Securities as they
appear on the books and records of the Trust on the record date

                                     A-1-5
<PAGE>

immediately preceding such date. Distributions on the Securities must be paid on
the dates payable (after giving effect to any Extension Period) to the extent
that the Trust has funds legally available for the payment of such distributions
in the Property Account of the Trust. The Trust's funds available for
Distribution to the Holders of the Securities will be limited to payments
received from the Debenture Issuer. The payment of Distributions out of moneys
held by the Trust is guaranteed by the Guarantor pursuant to the Guarantee.

      The Capital Securities shall be redeemable as provided in the Declaration.

Administrators, Chase Bank USA, National Association, as Delaware Trustee,
JPMorgan Chase Bank, National Association, as Institutional Trustee, the Holder,

in the assets of the Trust, including the designation of the terms of the Common

      Distributions payable on each Common Security will be identical in amount
to the Distributions payable on each Capital Security, which is at a variable
per annum rate of interest, reset quarterly, equal to LIBOR (as defined in the
Declaration) plus 1.95% (the "Coupon Rate") of the stated liquidation amount of
$1,000 per Capital Security (provided, however, that the Coupon Rate for any
Distribution Payment Period may not exceed the highest rate permitted by New
York law, as the same may be modified by United States law of general

at the then applicable Coupon Rate for each such quarterly period (to the extent

Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year and the actual number of days

would have been payable were it not for the Extension Period, to the extent
permitted by law. No Extension Period may end on a date other than a
Distribution Payment Date. At the end of any such Extension Period, the
Debenture Issuer shall pay all Deferred Interest then accrued and unpaid on the
Debentures; provided, however, that no Extension Period may extend beyond the
Maturity Date, Redemption Date or Special Redemption Date where applicable.
Prior to the termination of any Extension Period, the Debenture Issuer may
further extend such period, provided, that such period together with all such
previous and further consecutive extensions thereof shall not exceed 20
consecutive quarterly periods, or extend beyond the Maturity Date. Upon the
termination of any Extension Period and upon the payment of all Deferred
Interest, the Debenture Issuer may commence a new Extension Period, subject to
