                      (a) The Holders of a Majority in Liquidation Amount of
Capital Securities may, by vote, on behalf of the Holders of all of the Capital
Securities, waive any past Event of Default in respect of the Capital Securities
and its consequences, PROVIDED THAT, if the underlying Event of Default under
the Indenture:

                                 (i) is not waivable under the Indenture, the
                      Event of Default under the Declaration shall also not be
                      waivable; or

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

The foregoing provisions of this Section 2.6(a) shall be in lieu of Section
316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Declaration and the

such waiver shall extend to any subsequent or other Default or an Event of
Default with respect to the Capital Securities or impair any right consequent
thereon. Any waiver by the Holders of the Capital Securities of an Event of
Default with respect to the Capital Securities shall also be deemed to
constitute a waiver by the Holders of the Common Securities of any such Event of
Default with respect to the Common Securities for all purposes of this
Declaration without any further act, vote, or consent of the Holders of the
Common Securities.

                      (b) The Holders of a Majority in Liquidation Amount of the
Common Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, PROVIDED THAT, if the underlying Event of
Default under the Indenture:

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

                             (ii) requires the consent or vote of a Super
                      Majority to be waived, except where the Holders of the
                      Common Securities are deemed to have waived such Event of
                      Default under the Declaration as provided below in this
                      Section 2.6(b), the Event of Default under the Declaration
                      may only be waived by the vote of the Holders of at least
                      the proportion in aggregate liquidation amount of the
                      Common Securities that the relevant Super Majority
                      represents of the aggregate principal amount of the
                      Debentures outstanding;

PROVIDED FURTHER, each Holder of Common Securities will be deemed to have waived
any such Event of Default and all Events of Default with respect to the Common
Securities and their consequences if all Events of Default with respect to the
Capital Securities have been cured, waived or otherwise eliminated, and until
such Events of Default have been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the Holders of
the Capital Securities and only the Holders of the Capital Securities will have
the right to direct the Property Trustee in accordance with the terms of the
Securities. The foregoing provisions of this Section 2.6(b) shall be in lieu of
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby
expressly excluded from this Declaration and the Securities, as permitted by the
Trust Indenture Act. Subject to the foregoing provisions of this Section 2.6(b),
upon such waiver, any such Default shall cease to exist and any Event of Default
with respect to the Common Securities 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 with respect to
the Common Securities or impair any right consequent thereon.

                      (c) A waiver of an Event of Default under the Indenture by
the Property Trustee, at the direction of the Holders of the Capital Securities,
constitutes a waiver of the corresponding Event of Default under this
Declaration. The foregoing provisions of this Section 2.6(c) shall be in lieu of
Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of
the Trust Indenture Act

Capital Securities, the Administrative Trustees and the Sponsor, unless such
Event of Default shall have been cured or waived. The Sponsor and the

                      any trust or power conferred upon the Debenture Trustee
                      with respect to the Debentures, (B) waive any past default
                      that is waivable under the Indenture, or (C) exercise any
                      right to rescind or annul any declaration that the
                      principal of all the Debentures shall be due and payable;
                      or

                                 (viii) 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 an opinion of independent tax counsel experienced
                      in such matters to the effect that such amendment,
                      modification or termination will not cause more than an
                      insubstantial risk that the Trust will not be classified
                      as a grantor trust for United States federal income tax
                      purposes.

SECTION 3.8           POWERS AND DUTIES OF THE PROPERTY TRUSTEE.

                      (a) The legal title to the Debentures shall be owned by
and held of record in the name of the Property Trustee in trust for the benefit
of the Trust and the Holders. The right, title and interest of the Property
Trustee to the Debentures shall vest automatically in each Person who may
hereafter be appointed as Property Trustee in accordance with Section 5.6. Such
vesting and cessation of title shall be effective whether or not conveyancing
documents with regard to the Debentures have been executed and delivered.

                      (b) The Property Trustee shall not transfer its right,
title and interest in the Debentures to the Administrative Trustees or to the
Delaware Trustee (if the Property Trustee does not also act as Delaware
Trustee).

                      (c)    The Property Trustee shall:

                             (i) establish and maintain a segregated
                      non-interest bearing trust account (the "Property Trustee
                      Account") in the name of and under the exclusive control
                      of the Property Trustee on behalf of the Holders and, upon
                      the receipt of payments of funds made in respect of the
                      Debentures held by the Property

                                       18

                      Trustee, deposit such funds into the Property Trustee
                      Account and make payments or cause the Paying Agent to
                      make payments to the Holders from the Property Trustee
                      Account in accordance with Section 6.1; funds in the
                      Property Trustee Account shall be held uninvested until
                      disbursed in accordance with this Declaration; and the
                      Property Trustee Account shall be an account that is
                      maintained with a banking institution the rating on whose
                      long-term unsecured indebtedness by a "nationally
                      recognized statistical rating organization," as that term
                      is defined for purposes of Rule 436(g)(2) under the
                      Securities Act, is at least equal to the rating assigned
                      to the Capital Securities, unless the Capital Securities
                      are not rated, in which case the banking institution's
                      long-term unsecured indebtedness shall be rated at least
                      investment grade by a "nationally recognized statistical
                      rating organization";

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

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

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

                      (e) Subject to Section 3.9(a), the Property Trustee shall
take any Legal Action which arises out of or in connection with an Event of
Default of which a Responsible Officer has actual knowledge or the Property
Trustee's duties and obligations under this Declaration or the Trust Indenture
Act; and if the Property Trustee shall have failed to take such Legal Action
following a written request from the Holders, the Holders of the Capital
Securities may, to the fullest extent permitted by law, take such Legal Action,
to the same extent as if such Holders of Capital Securities held an aggregate
principal amount of Debentures equal to the aggregate liquidation amount of such
Capital Securities, without first proceeding against the Property Trustee or the
Trust; 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 the principal of or premium, if any, or interest (including Compounded
Interest and Additional Sums, if any) or Liquidated Damages, if any, on the
Debentures on the date such principal, premium, if any, or interest (including
Compounded Interest and Additional Sums, if any) or Liquidated Damages, if any,
is otherwise payable (or in the case of redemption, on the redemption date),
then a Holder of Capital Securities may directly institute a proceeding for
enforcement of payment to such Holder of the principal of or premium, if any, or
interest (including Compounded Interest and Additional Sums, if any) or
Liquidated Damages, if any, 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 Holders of the Common
Securities will be subrogated to the rights of such Holder of Capital Securities
to the extent of any payment made

                                       19
<PAGE>   26



by the Debenture Issuer to such Holder of Capital Securities in such Direct
Action. Except as provided in the preceding sentences, the Holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures.

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

                                 (i) the Trust has been completely liquidated
                      and the proceeds of the liquidation distributed to the
                      Holders pursuant to the terms of the Securities and this
                      Declaration; or

                                 (ii) a successor Property Trustee has been
                      appointed and has accepted that appointment in accordance
                      with Section 5.6 (a "Successor Property Trustee").

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

                      (h) The Property Trustee shall be authorized to undertake
any actions set forth in ss.317(a) of the Trust Indenture Act.

                      (i) For such time as the Property Trustee is the Paying
Agent, the Property Trustee may authorize one or more Persons to act as
additional Paying Agents and to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all Securities and
any such Paying Agent shall comply with ss. 317(b) of the Trust Indenture Act.
Any such additional Paying Agent may be removed by the Property Trustee at any
time the Property Trustee remains as Paying Agent and a successor Paying Agent
or additional Paying Agents may be (but are not required to be) appointed at any
time by the Property Trustee while the Property Trustee is acting as Paying
Agent.

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

                      Notwithstanding anything expressed or implied to the
contrary in this Declaration or any Annex or Exhibit hereto, (i) the Property
Trustee must exercise the powers set forth in this Section 3.8 in a manner that
is consistent with the purposes and functions of the Trust set out in Section
3.3, and (ii) the Property Trustee shall not take any action that is
inconsistent with the purposes and functions of the Trust set out in Section
3.3.

SECTION 3.9 CERTAIN DUTIES AND RESPONSIBILITIES OF THE PROPERTY TRUSTEE.

                      (a) The Property Trustee, before the occurrence of any
Event of Default (of which, other than in the case of Events of Default under
Sections 5.01(a) and 5.01(b) of the Indenture, which the Property Trustee is
deemed to have knowledge of as provided in Section 2.7(b) hereof, a Responsible
Officer of the Property Trustee has actual knowledge) and after the curing or



                                       20
<PAGE>   27


waiving of all such Events of Default that may have occurred, shall undertake to
perform only such duties as are specifically set forth in this Declaration and
in the Securities and no implied covenants shall be read into this Declaration
against the Property Trustee. In case an Event of Default has occurred (that has
not been cured or waived pursuant to Section 2.6) of which a Responsible Officer
has actual knowledge, the Property Trustee shall exercise such of the rights and
powers vested in it by this 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) No provision of this Declaration shall be construed to
relieve the Property Trustee from liability for its own negligent action, its
own negligent failure to act, or its own willful misconduct, except that:

                             (i) prior to the occurrence of an Event of Default
                      (of which, other than in the case of Events of Default
                      under Sections 5.01(a) and 5.01(b) of the Indenture, which
                      the Property Trustee is deemed to have knowledge of as
                      provided in Section 2.7(b) hereof, a Responsible Officer
                      of the Property Trustee has actual knowledge) and after
                      the curing or waiving of all such Events of Default that
                      may have occurred:

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

                             (B) in the absence of bad faith on the part of the
                             Property Trustee, the Property Trustee may
                             conclusively rely, as to the truth of the
                             statements and the correctness of the opinions
                             expressed therein, upon any certificates or
                             opinions furnished to the Property Trustee and
                             conforming to the requirements of this Declaration;
                             PROVIDED, HOWEVER, that in the case of any such
                             certificates or opinions that by any provision
                             hereof are specifically required to be furnished to
                             the Property Trustee, the Property Trustee shall be
                             under a duty to examine the same to determine
                             whether or not on their face they conform to the
                             requirements of this Declaration;

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

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



                                       21
<PAGE>   28



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

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

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

                             (vii) the Property 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. Money held by
                      the Property Trustee need not be segregated from other
                      funds held by it except in relation to the Property
                      Trustee Account maintained by the Property Trustee
                      pursuant to Section 3.8(c)(i) and except to the extent
                      otherwise required by law; and

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

                      or other experts of its selection, and the advice or
                      opinion of such counsel and experts with respect to legal
                      matters or advice within the scope of such experts' area
                      of expertise shall be full and complete authorization and

                      omitted by it hereunder in good faith and in accordance
                      with such advice or opinion; such counsel may be counsel
                      to the Sponsor or any of its Affiliates, and may include

or exercise any right, power, duty or obligation conferred or imposed on it, in
any jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable law, to

                    replacement, conveyance, transfer or lease does not
                    adversely affect the rights, preferences and privileges of
                    the Holders (including the holders of any Successor
                    Securities) in any material respect (other than with
                    respect to any dilution of the interests of such Holders or
                    holders, as the case may be, in the Successor Entity);

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

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

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 the Successor Entity not to be classified as a grantor
trust for United States federal income tax purposes.

                    The Sponsor acknowledges the rights of the Holders of

enforcement of its payment obligations in respect of the Debentures.

SECTION 4.4         RIGHT TO DISSOLVE TRUST.

required by applicable law, to cause the Debentures to be distributed to the
Holders in liquidation of the Trust. Such right is subject to the Sponsor's
having received (i) an Opinion of Counsel to the effect that such distribution
will not cause the Holders of Capital Securities to recognize gain or loss for
United States federal income tax purposes and (ii) any required regulatory
approval.

                            (B) until the assets of the Trust have been

Default shall have occurred and be continuing after the issuance of the
Securities, the Holders of the Capital Securities shall use their best efforts
to promptly appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with this Section 5.6.

                    (e) If no Successor Property Trustee or Successor Delaware
Trustee shall have been appointed and accepted appointment as provided in this
Section 5.6 within 60 days after delivery of an instrument of resignation or
removal, the Property Trustee or Delaware Trustee

<PAGE>   39

resigning or being removed, as applicable, may petition any court of competent
jurisdiction for appointment of a Successor Property Trustee or Successor
Delaware Trustee. Such court may thereupon, after prescribing such notice, if

SECTION 5.7         VACANCIES AMONG TRUSTEES.

                    If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.l, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur. A
resolution certifying the existence of such vacancy by the Administrative
Trustees or, if there are more than two, a majority of the Administrative
Trustees shall be conclusive evidence of the existence of such vacancy. The
vacancy shall be filled with a Trustee appointed in accordance with Section 5.6.

SECTION 5.8         EFFECT OF VACANCIES.

                    The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee shall not operate to dissolve, liquidate or annul the Trust or to
terminate this Declaration. Whenever a vacancy in the number of Administrative
Trustees shall occur, until such vacancy is filled by the appointment of an
Administrative Trustee in accordance with Section 5.6, the Administrative
Trustees in office, regardless of their number, shall have all the powers
granted to the Administrative Trustees and shall discharge all the duties
imposed upon the Administrative Trustees by this Declaration.

SECTION 5.9         MEETINGS.

                    If there is more than one Administrative Trustee, meetings
of the Administrative Trustees shall be held from time to time upon the call of

Notice of any in-person meetings of the Administrative Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 24 hours before such meeting. Notice of
any telephonic meetings of the Administrative Trustees or any committee thereof
shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours

                                       33

<PAGE>   40

before a meeting. Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting. The presence (whether in person or by
telephone) of an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Declaration, any action of the Administrative
Trustees may be taken at a meeting by vote of a majority of the Administrative
Trustees present (whether in person or by telephone) and eligible to vote with
respect to such matter, PROVIDED THAT, a Quorum is present, or without a meeting
by the unanimous written consent of the Administrative Trustees. In the event
there is only one Administrative Trustee, any and all action of such
Administrative Trustee shall be evidenced by a written consent of such
Administrative Trustee.

SECTION 5.10        DELEGATION OF POWER.

                    (a) Any Administrative Trustee may, by power of attorney
consistent with applicable law, delegate to any other natural person over the

contemplated in Section 3.6, including any registration statement or amendment
thereto filed with the Commission, or making any other governmental filing.

                    (b) The Administrative Trustees shall have power to delegate
from time to time to such of their number or to officers of the Trust the doing
of such things and the execution of such instruments either in the name of the
Trust or the names of the Administrative Trustees or otherwise as the
Administrative Trustees may deem expedient, to the extent such delegation is not
prohibited by applicable law or contrary to the provisions of this Declaration.

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

                    Any Person into which the Property Trustee or the Delaware
Trustee or any Administrative Trustee that is not a natural person, as the case
may be, may be merged or converted or with which it may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which the
Property 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 Property Trustee or the Delaware Trustee, as the case may be,
shall be the successor of the Property 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
Delaware Secretary of State as contemplated in Section 5.6(h).

SECTION 6.1         DISTRIBUTIONS.

                                       34

<PAGE>   41

interest (including Compounded Interest and Additional Sums), premium and/or
principal on the Debentures held by the Property Trustee or Liquidated Damages
or any other payments pursuant to the Registration Rights Agreement or
Liquidated Damages Agreement with respect to the Debentures held by the Property
Trustee (the amount of any such payment being a "Payment Amount"), the Property
Trustee shall and is directed, to the extent funds are available for that
purpose, to make a distribution (a "Distribution") of the Payment Amount to
Holders in accordance with the terms of the Securities.

                                   ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1         GENERAL PROVISIONS REGARDING SECURITIES.

                    (a) The Administrative Trustees shall, on behalf of the
Trust, issue one class of capital securities representing undivided preferred
beneficial interests in the assets of the Trust having such terms as are set
forth in Annex I (the "Series A Capital Securities") and one class of common
securities representing undivided common beneficial interests in the assets of
the Trust having such terms as are set forth in Annex I (the "Common
Securities"). The Administrative Trustees shall, on behalf of the Trust, issue
one class of capital securities representing undivided preferred beneficial
interests in the Trust having such terms as set forth in Annex I (the "Series B
Capital Securities") in exchange for the Series A Capital Securities accepted
for exchange in the Exchange Offer, which Series B Capital Securities shall not
bear the legends required by Section 9.2(i) unless the Holder of such Series A
Capital Securities is either (A) a broker-dealer who purchased such Series A
Capital Securities directly from the Trust for resale pursuant to Rule 144A or
any other available exemption under the Securities Act, (B) a Person
participating in the distribution of the Series A Capital Securities or (C) a
Person who is an Affiliate of the Sponsor or the Trust. The Trust shall issue no
securities or other interests in the assets of the Trust other than the Capital
Securities and the Common Securities.

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

                    (c) Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued and,
subject to the terms of this Declaration, fully paid and nonassessable.

                    (d) Every Person, by virtue of having become a Holder or a
Capital Security Beneficial Owner 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.

SECTION 7.2         EXECUTION AND AUTHENTICATION.

                    (a) The Securities shall be signed on behalf of the Trust by
an Administrative Trustee. In case any Administrative Trustee of the Trust who
shall have signed any of the Securities shall cease to be such Administrative
Trustee before the Securities so signed shall be delivered by the Trust, such
Securities nevertheless may be delivered as though the Person who signed such

                                       35

<PAGE>   42

Securities had not ceased to be such Administrative Trustee; and any Securities
may be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Administrative Trustees of the Trust,
although at the date of the execution and delivery of this Declaration any such
person was not an Administrative Trustee.

                    (b) One Administrative Trustee shall sign the Capital
Securities for the Trust by manual or facsimile signature. Unless otherwise
determined by an Administrative Trustee on behalf of the Trust, an
Administrative Trustee shall sign the Common Securities for the Trust by manual
signature.

                    A Capital Security shall not be valid until authenticated by
the manual signature of an authorized signatory of the Property Trustee. The
signature shall be conclusive evidence that the Capital Security has been
authenticated under this Declaration. A Common Security shall be valid upon
execution by an Administrative Trustee without any act of the Property Trustee.

                    Upon a written order of the Trust signed by one
Administrative Trustee, the Property Trustee shall authenticate the Capital
Securities for original issue. The aggregate number of Capital Securities
outstanding at any time shall not exceed the number set forth in Annex I hereto
except as provided in Section 7.6.

                    The Property Trustee may appoint an authenticating agent
acceptable to the Trust to authenticate Capital Securities. An authenticating
agent may authenticate Capital Securities whenever the Property Trustee may do
so. Each reference in this Declaration to authentication by the Property Trustee
includes authentication by such agent. An authenticating agent has the same
rights as the Property Trustee hereunder with respect to the Sponsor or an
Affiliate.

SECTION 7.3         FORM AND DATING.

                    The Capital Securities shall be evidenced by one or more
certificates substantially in the form of Exhibit A-1, and the Common Securities
shall be evidenced by one or more certificates substantially in the form of
Exhibit A-2. The Property Trustee's certificate of authentication shall be
substantially in the form set forth in Exhibit A-1. Certificates representing
the Securities may be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to an Administrative Trustee, as
evidenced by the execution thereof. The Securities may have letters, "CUSIP" or
other 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 Administrative Trustees,
as evidenced by their execution thereof. The Trust at the direction of the
Sponsor, shall furnish any such legend not contained in Exhibit A-1 to the
Property 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 Property
Trustee and the Sponsor, by their execution and delivery of this Declaration,
expressly agree to such terms and provisions and to be bound thereby.

                    (a) GLOBAL CAPITAL SECURITY. Capital Securities offered and
sold to QIBs in reliance on Rule 144A, as provided in the Purchase Agreement,
shall be issued in the form of a single permanent global Capital Security in
definitive, fully registered form without distribution coupons with the
appropriate global legends and Restricted Securities Legend set forth in Exhibit
A-1 hereto (the "Global Capital Security"), which shall be deposited on behalf
of the purchasers of the Capital Securities represented thereby with the
Property Trustee, at its Corporate Trust Office, as custodian for the Clearing
Agency, and registered in the name of the Clearing Agency or a nominee of the
Clearing Agency, duly executed by the Trust and authenticated by the Property
Trustee as hereinafter provided. The number of Capital Securities represented by
the Global Capital Security may from time to time be increased or decreased by
adjustments made on the records of the Property Trustee and the Clearing Agency
or its nominee as hereinafter provided.

                    (b) BOOK-ENTRY PROVISIONS. This Section 7.3(b) shall apply
only to the Global Capital Security and such other Capital Securities in global
form as may be authorized by the Trust to be deposited with or on behalf of the
Clearing Agency.

                    An Administrative Trustee shall execute and the Property
Trustee shall, in accordance with this Section 7.3, authenticate and make
available for delivery initially a single Global Capital Security that (i) shall
be registered in the name of Cede & Co. or other nominee of such Clearing
Agency, and (ii) shall be delivered by the Property Trustee to such Clearing
Agency or pursuant to such Clearing Agency's written instructions or, if no such
written instructions are received by the Property Trustee, held by the Property
Trustee as custodian for the Clearing Agency.

                    Members of, or participants in, the Clearing Agency
("Participants") shall have no rights under this Declaration with respect to the
Global Capital Security held on their behalf by the Clearing Agency or by the
Property Trustee as the custodian of the Clearing Agency or under such Global
Capital Security, and the Clearing Agency may be treated by the Trust, the
Property Trustee and any agent of the Trust or the Property Trustee as the
absolute owner of such Global Capital Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Trust, the
Property Trustee or any agent of the Trust or the Property Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Clearing Agency or impair, as between the Clearing Agency and its
Participants, the operation of customary practices of such Clearing Agency
governing the exercise of the rights of a holder of a beneficial interest in the
Global Capital Security.

                    (c) DEFINITIVE CAPITAL SECURITIES. Except as provided in
Section 7.9 or 9.2(f)(i), owners of beneficial interests in the Global Capital
Security will not be entitled to receive physical delivery of certificated
Capital Securities ("Definitive Capital Securities"). Purchasers of Securities
who are "accredited investors" (as defined in Rule 501(a)(1), (2), (3) or (7)
under the Securities Act) and who are not QIBs will receive Capital Securities
in the form of individual certificates in definitive, fully registered form
without distribution coupons and with the Restricted Securities Legend set forth
in Exhibit A-1 hereto ("Restricted Definitive Capital Securities"); PROVIDED,
HOWEVER, that upon registration of transfer of such Restricted Definitive
Capital Securities to a QIB, such Restricted Definitive Capital Securities will,
unless the Global Capital Security has previously been exchanged, be exchanged
for an interest in the Global Capital Security pursuant to the

                                       37

<PAGE>   44

provisions of Section 9.2. Restricted Definitive Capital Securities will bear
the Restricted Securities Legend set forth on Exhibit A-1 unless removed in
accordance with this Section 7.3 or Section 9.2.

SECTION 7.4         REGISTRAR, PAYING AGENT AND EXCHANGE AGENT.

                    The Trust shall maintain in Wilmington, Delaware (i) an
office or agency where Capital Securities may be presented for registration of
transfer ("Registrar"), (ii) an office or agency where Capital Securities may be
presented for payment ("Paying Agent") and (iii) an office or agency where
Securities may be presented for exchange ("Exchange Agent"). The Registrar shall
keep a register of the Capital Securities and of their transfer. The Trust may
appoint the Registrar, the Paying Agent and the Exchange Agent and may appoint
one or more co-registrars, one or more additional paying agents and one or more
additional Exchange Agents in such other locations as it shall determine. The
term "Registrar" includes any additional registrar, the term "Paying Agent"
includes any additional paying agent and the term "Exchange Agent" includes any
additional Exchange Agent. The Trust may change any Paying Agent, Registrar,
co-registrar or Exchange Agent without prior notice to any Holder. The Paying
Agent shall be permitted to resign as Paying Agent upon 30 days' written notice
to the Property Trustee, the Administrative Trustees and the Sponsor. The Trust
shall notify the Property Trustee of the name and address of any Agent not a
party to this Declaration. If the Trust fails to appoint or maintain another
entity as Registrar, Paying Agent or Exchange Agent, the Property Trustee shall
act as such. The Trust or any of its Affiliates may act as Paying Agent,
Registrar, or Exchange Agent. The Trust shall act as Paying Agent, Registrar and
Exchange Agent for the Common Securities.

                    The Trust initially appoints the Property Trustee as
Registrar, Paying Agent and Exchange Agent for the Capital Securities.

SECTION 7.5         PAYING AGENT TO HOLD MONEY IN TRUST.

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

SECTION 7.6         REPLACEMENT SECURITIES.

                    If a Holder claims that a Security owned by it has been
lost, destroyed or wrongfully taken or if such Security is mutilated and is
surrendered to the Trust or in the case of the Capital Securities to the
Property Trustee, an Administrative Trustee shall execute and the Property
Trustee shall authenticate and make available for delivery a replacement
Security if the Property

                                       38

<PAGE>   45

Trustee's requirements are met. An indemnity bond must be provided by the Holder
which, in the judgment of the Property Trustee, is sufficient to protect the
Trustees, the Sponsor, the Trust or any authenticating agent from any loss which
any of them may suffer if a Security is replaced. The Trust may charge such
Holder for its expenses in replacing a Security.

SECTION 7.7         OUTSTANDING CAPITAL SECURITIES.

                    The Capital Securities outstanding at any time are all the
Capital Securities authenticated by the Property Trustee except for those
canceled by it, those delivered to it for cancellation, and those described in
this Section as not outstanding.

                    If a Capital Security is replaced, paid or purchased
pursuant to Section 7.6 hereof, it ceases to be outstanding unless the Property
Trustee receives proof satisfactory to it that the replaced, paid or purchased
Capital Security is held by a bona fide purchaser.

                    If Capital Securities are considered paid in accordance with
the terms of this Declaration, they cease to be outstanding and Distributions on
them shall cease to accumulate.

                    A Capital Security does not cease to be outstanding because
one of the Trust, the Sponsor or an Affiliate of the Sponsor holds the Security.

SECTION 7.8         CAPITAL SECURITIES IN TREASURY.

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

SECTION 7.9         TEMPORARY SECURITIES.

                    (a) Until Definitive Capital Securities are ready for
delivery, the Trust may prepare and, in the case of the Capital Securities, the
Property Trustee shall authenticate temporary Securities. Temporary Securities
shall be substantially in the form of Definitive Capital Securities but may have
variations that the Trust considers appropriate for temporary Securities.
Without unreasonable delay, the Trust shall prepare and, in the case of the
Capital Securities, the Property Trustee shall authenticate Definitive Capital
Securities in exchange for temporary Securities.

                    (b) The Global Capital Security deposited with the Clearing
Agency or with the Property Trustee as custodian for the Clearing Agency
pursuant to Section 7.3 shall be transferred to the beneficial owners thereof in
the form of Definitive Capital Securities only if such transfer complies with
Section 9.2 and (i) the Clearing Agency notifies the Sponsor that it is
unwilling or unable to continue as Clearing Agency for such Global Capital
Security or if at any time such Clearing Agency ceases to be a "clearing agency"
registered under the Exchange Act, and, in each case, a clearing agency is not
appointed by the Sponsor within 90 days of receipt of such notice or

                                       39

<PAGE>   46

of becoming aware of such condition, (ii) a Default or an Event of Default has
occurred and is continuing, or (iii) the Trust at its sole discretion elects to
cause the issuance of Definitive Capital Securities.

                    (c) Any Global Capital Security that is transferable to the
beneficial owners thereof in the form of Definitive Capital Securities pursuant
to this Section 7.9 shall be surrendered by the Clearing Agency to the Property
Trustee to be so transferred, in whole or from time to time in part, without
charge, and the Property Trustee shall authenticate and make available for
delivery, upon such transfer of each portion of such Global Capital Security, an
equal aggregate liquidation amount of Capital Securities of authorized
denominations in the form of Definitive Capital Securities. Any portion of the
Global Capital Security transferred pursuant to this Section shall be registered
in such names as the Clearing Agency shall direct. Any Definitive Capital
Security delivered in exchange for an interest in the Restricted Global Capital
Security shall, except as otherwise provided by Sections 7.3 and 9.1, bear the
Restricted Securities Legend set forth in Exhibit A-l hereto.

                    (d) Subject to the provisions of Section 7.9(c), the Holder
of the Global Capital Security may grant proxies and otherwise authorize any
Person, including Participants and Persons that may hold interests through
Participants, to take any action which such Holder is entitled to take under
this Declaration or the Securities.

                    (e) In the event of the occurrence of any of the events
specified in Section 7.9(b), the Trust will promptly make available to the
Property Trustee a reasonable supply of certificated Capital Securities in
fully registered form without distribution coupons.

SECTION 7.10        CANCELLATION.

                    The Trust at any time may deliver Capital Securities to the
Property Trustee for cancellation. The Registrar, Paying Agent and Exchange
Agent shall forward to the Property Trustee any Capital Securities surrendered
to them for registration of transfer, redemption, exchange or payment. The
Property Trustee shall promptly cancel all Capital Securities surrendered for
registration of transfer, redemption, exchange, payment, replacement or
cancellation and shall dispose of canceled Capital Securities in accordance with
its customary procedures unless the Trust otherwise directs. The Trust may not
issue new Capital Securities to replace Capital Securities that it has paid or
that have been delivered to the Property Trustee for cancellation or that any
Holder has exchanged.

SECTION 7.11        CUSIP NUMBERS.

                    The Trust in issuing the Capital Securities may use "CUSIP"
numbers (if then generally in use), and, if so, the Property Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders of Capital
Securities; PROVIDED THAT, any such notice may state that no representation is
made as to the correctness of such numbers either as printed on the Capital
Securities or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Capital
Securities, and any such redemption shall not be

                                       40

<PAGE>   47

affected by any defect in or omission of such numbers. The Sponsor will promptly
notify the Property Trustee of any change in the CUSIP numbers.

                                  ARTICLE VIII
                              DISSOLUTION OF TRUST

SECTION 8.1         DISSOLUTION OF TRUST.

                    (a) The Trust shall automatically dissolve:

                        (i)   upon the bankruptcy of the Sponsor;

                        (ii)  upon the filing of a certificate of dissolution
                    or liquidation or its equivalent with respect to the
                    Sponsor; or the revocation of the Sponsor's charter and the
                    expiration of 90 days after the date of revocation without
                    a reinstatement thereof;

                        (iii) following the distribution of a Like Amount of
                    the Debentures to the Holders, PROVIDED THAT, the Property
                    Trustee has received written notice from the Sponsor
                    directing the Property Trustee to dissolve the Trust (which
                    direction is optional, and except as otherwise expressly
                    provided below, within the discretion of the Sponsor), and
                    PROVIDED, FURTHER, that such direction and such
                    distribution is conditioned on (a) the receipt by the
                    Sponsor of any and all required regulatory approvals, and
                    (b) the Sponsor's receipt and delivery to the
                    Administrative Trustees of an opinion of independent tax
                    counsel experienced in such matters, which opinion may rely
                    on public or private rulings of the Internal Revenue
                    Service, to the effect that the Holders of the Capital
                    Securities will not recognize any gain or loss for United
                    States federal income tax purposes as a result of the
                    dissolution of the Trust and the distribution of
                    Debentures;

                        (iv)  upon the entry of a decree of judicial
                    dissolution of the Trust by a court of competent
                    jurisdiction;

                        (v)   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;

                        (vi)  upon the redemption or repayment of the
                    Debentures or at such time as no Debentures are
                    outstanding; or

                        (vii) the expiration of the term of the Trust
                    provided in Section 3.14.

                    (b) As soon as is practicable upon completion of winding up
of the Trust following the occurrence of an event referred to in Section 8.1(a)
and the satisfaction of creditors of the Trust in accordance with applicable
law, the Administrative Trustees shall terminate the Trust

                                       41

<PAGE>   48

by filing a certificate of cancellation with the Secretary of State of the State
of Delaware in accordance with the Business Trust Act.

                    (c) The provisions of Section 3.9 and Article X shall
survive the dissolution and termination of the Trust.

                                   ARTICLE IX
                              TRANSFER OF INTERESTS

SECTION 9.1         TRANSFER OF SECURITIES.

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

                    (b) Subject to this Article IX, Capital Securities may only
be transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Declaration. To the fullest extent permitted by law, any
transfer or purported transfer of any Security not made in accordance with this
Declaration shall be null and void.

                    (c) For so long as the Securities remain outstanding, the
Sponsor agrees (i) not to transfer ownership of the Common Securities of the
Trust, provided that any permitted successor of the Sponsor under the Indenture
may succeed to the Sponsor's ownership of the Common Securities, (ii) not to
cause, as Sponsor of the Trust, or to permit, as Holder of the Common
Securities, the dissolution, winding-up or liquidation of the Trust, except as
provided in this Declaration and (iii) to use its best efforts to cause the
Trust (a) to remain a business trust, except in connection with the distribution
of Debentures to the Holders in liquidation of the Trust, the redemption of all
of the Securities, or certain mergers, consolidations or amalgamations, each as
permitted by this Declaration, and (b) to otherwise continue to be classified as
a grantor trust for United States federal income tax purposes.

                    (d) The Registrar shall provide for the registration of
Capital Securities and of the transfer of Capital 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 Capital Securities, an Administrative Trustee shall cause one or more new
Capital Securities to be issued in the name of the designated transferee or
transferees. Every Capital 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 Capital Security surrendered for registration of
transfer shall be delivered to the Registrar and canceled in accordance with
Section 7.10. A transferee of a Capital Security shall be entitled to the rights
and subject to the obligations of a Holder hereunder upon the receipt by such
transferee of a Capital Security. By acceptance of a Capital Security or any
interest therein, each transferee shall be deemed to have agreed to be bound by
this Declaration.

SECTION 9.2         TRANSFER PROCEDURES AND RESTRICTIONS.

                    (a) GENERAL. Except as otherwise provided in Section 9.2(b),
if Capital Securities are issued upon the transfer, exchange or replacement of
Capital Securities bearing the Restricted Securities Legend set forth in
Exhibit A-1 hereto, or if a request is made to remove such Restricted Securities
Legend on Capital Securities, the Capital Securities so issued shall bear the
Restricted Securities Legend, or the Restricted Securities Legend shall not be
removed, as the case may be, unless there is delivered to the Trust and the
Property Trustee such satisfactory evidence, which shall include an Opinion of
Counsel, as may be reasonably required by the Trust and the Property Trustee,
that neither the Restricted Securities Legend nor the restrictions on transfer
set forth therein are required to ensure that transfers thereof are made
pursuant to an exception from the registration requirements of the Securities
Act or, with respect to Restricted Capital Securities, that such Securities are
not "restricted" within the meaning of Rule 144. Upon provision of such
satisfactory evidence, the Property Trustee, at the written direction of an
Administrative Trustee on behalf of the Trust, shall authenticate and deliver
Capital Securities that do not bear the legend.

                    (b) TRANSFERS AFTER EFFECTIVENESS OF A REGISTRATION
STATEMENT. After the effectiveness of a Registration Statement with respect to
any Capital Securities, all requirements pertaining to legends on such Capital
Securities will cease to apply (other than the legend requiring that transfers
of Capital Securities be made in blocks having an aggregate liquidation amount
of not less than $100,000 (100 Capital Securities) and multiples of $1,000 in
excess thereof), and beneficial interests in the Global Capital Security without
legends will be available to transferees of such Capital Securities, upon
exchange of the transferring Holder's Restricted Definitive Capital Security or
directions to transfer such Holder's beneficial interest in the Global Capital
Security, as the case may be. No such transfer or exchange of a Restricted
Definitive Capital Security or of an interest in the Global Capital Security
shall be effective unless the transferor delivers to the Property Trustee a
certificate in a form substantially similar to that attached hereto as the form
of "Assignment" in Exhibit A-1. Except as otherwise provided in Section 9.2(m),
after the effectiveness of a Registration Statement, an Administrative Trustee
on behalf of the Trust shall issue and the Property Trustee, upon a written
order of the Trust signed by one Administrative Trustee, shall authenticate a
Global Capital Security without the Restricted Securities Legend (the
"Unrestricted Global Capital Security") to deposit with the Clearing Agency to
evidence transfers of beneficial interests from the Global Capital Security and
Restricted Definitive Capital Securities.

                    (c) TRANSFER AND EXCHANGE OF DEFINITIVE CAPITAL SECURITIES.
When Definitive Capital Securities are presented to the Registrar or
co-registrar:

                    (x) to register the transfer of such Definitive Capital
              Securities; or

                    (y) to exchange such Definitive Capital Securities which
              became mutilated, destroyed, defaced, stolen or lost, for an equal
              number of Definitive Capital Securities, the Registrar or
              co-registrar shall register the transfer or make the exchange as
              requested if its reasonable requirements for such transaction are
              met;

              PROVIDED, HOWEVER, that the Definitive Capital Securities
              surrendered for registration of transfer or exchange:

                                       43

<PAGE>   50

                             (i) shall be duly endorsed or accompanied by a
                      written instrument of transfer in form reasonably
                      satisfactory to the Trust and the Registrar or
                      co-registrar, duly executed by the Holder thereof or his
                      attorney duly authorized in writing; and

                             (ii) in the case of Definitive Capital Securities
                      that are Restricted Definitive Capital Securities:

                             (A) if such Restricted Capital Securities are being
                             delivered to the Registrar by a Holder for
                             registration in the name of such Holder, without
                             transfer, certification(s) from such Holder to that
                             effect; or

                             (B) if such Restricted Capital Securities are being
                             transferred: (i) certification(s) in a form
                             substantially similar to that attached hereto as
                             the form of "Assignment" in Exhibit A-1, and (ii)
                             if the Trust or Registrar so requests, evidence
                             reasonably satisfactory to them as to the
                             compliance with the restrictions set forth in the
                             Restricted Securities Legend.

                    (d) RESTRICTIONS ON TRANSFER OF A DEFINITIVE CAPITAL
SECURITY FOR A BENEFICIAL INTEREST IN THE GLOBAL CAPITAL SECURITY. A Definitive
Capital Security may not be exchanged for a beneficial interest in the Global
Capital Security except upon satisfaction of the requirements set forth below.
Upon receipt by the Property Trustee of a Definitive Capital Security, duly
endorsed or accompanied by appropriate instruments of transfer, in form
satisfactory to the Property Trustee, together with:

                        (i) if such Definitive Capital Security is a
                    Restricted Capital Security, certification(s) in a form
                    substantially similar to that attached hereto as the form
                    of "Assignment" in Exhibit A-1; and

                        (ii) whether or not such Definitive Capital
                    Security is a Restricted Capital Security, written
                    instructions directing the Property Trustee to make, or to
                    direct the Clearing Agency to make, an adjustment on its
                    books and records with respect to the Global Capital
                    Security to reflect an increase in the number of the
                    Capital Securities represented by such Global Capital
                    Security,

then the Property Trustee shall cancel such Definitive Capital Security and
cause, or direct the Clearing Agency to cause, the aggregate number of Capital
Securities represented by the Global Capital Security to be increased
accordingly. If the Global Capital Security is not then outstanding, an
Administrative Trustee on behalf of the Trust shall issue and the Property
Trustee shall authenticate, upon written order of any Administrative Trustee, a
new Global Capital Security representing an appropriate number of Capital
Securities.

                    (e) TRANSFER AND EXCHANGE OF THE GLOBAL CAPITAL SECURITY.
Subject to Section 9.2(f), the transfer and exchange of the Global Capital
Security or beneficial interests therein shall be effected through the Clearing
Agency in accordance with this Declaration (including applicable restrictions on
transfer set forth herein, if any) and the procedures of the Clearing Agency
therefor.

                    (f) TRANSFER OF A BENEFICIAL INTEREST IN THE GLOBAL CAPITAL
SECURITY FOR A DEFINITIVE CAPITAL SECURITY.

                        (i) Any Person having a beneficial interest in the
                    Global Capital Security may upon request, but only upon 20
                    days prior notice to the Property Trustee, and if
                    accompanied by the information specified below, exchange
                    such beneficial interest for a Definitive Capital Security
                    representing the same number of Capital Securities. Upon
                    receipt by the Property Trustee from the Clearing Agency
                    or its nominee on behalf of any Person having a beneficial
                    interest in the Global Capital Security of written
                    instructions or such other form of instructions as is
                    customary for the Clearing Agency or the Person designated
                    by the Clearing Agency as having such a beneficial
                    interest in a Restricted Capital Security and
                    certification(s) from the transferor in a form
                    substantially similar to that attached hereto as the form
                    of "Assignment" in Exhibit A-1, which may be submitted by
                    facsimile, then the Property Trustee will cause the
                    aggregate number of Capital Securities represented by the
                    Global Capital Security to be reduced on its books and
                    records and, following such reduction, the Trust will
                    execute and the Property Trustee will authenticate and
                    make available for delivery to the transferee a Definitive
                    Capital Security.

                        (ii) Definitive Capital Securities issued in
                    exchange for a beneficial interest in the Global Capital
                    Security pursuant to this Section 9.2(f) shall be
                    registered in such names and in such authorized
                    denominations as the Clearing Agency, pursuant to
                    instructions from its Clearing Agency Participants or
                    indirect participants or otherwise, shall instruct the
                    Property Trustee in writing. The Property Trustee shall
                    deliver such Capital Securities to the Persons in whose
                    names such Capital Securities are so registered in
                    accordance with such instructions of the Clearing Agency.

                    (g) RESTRICTIONS ON TRANSFER AND EXCHANGE OF THE GLOBAL
CAPITAL SECURITY. Notwithstanding any other provisions of this Declaration
(other than the provisions set forth in subsection (h) of this Section 9.2), the
Global Capital Security may not be transferred as a whole except by the Clearing
Agency to a nominee of the Clearing Agency or another nominee of the Clearing
Agency or by the Clearing Agency or any such nominee to a successor Clearing
Agency or a nominee of such successor Clearing Agency.

                    (h) AUTHENTICATION OF DEFINITIVE CAPITAL SECURITIES. If at
any time:

                        (i)   a Default or an Event of Default has occurred
                    and is continuing,

                        (ii)  the Trust, in its sole discretion, notifies
                    the Property Trustee in writing that it elects to cause
                    the issuance of Definitive Capital Securities under this
                    Declaration, or

                        (iii) the Clearing Agency notifies the Sponsor that
                    it is unwilling or unable to continue as Clearing Agency
                    for such Global Capital Security or if at any time

                                       45

                    such Clearing Agency ceases to be a "clearing agency"
                    registered under the Exchange Act, and, in each case, a
                    clearing agency is not appointed by the Sponsor within 90
                    days of receipt of such notice or of becoming aware of
                    such condition,

then an Administrative Trustee on behalf of the Trust will execute, and the
Property Trustee, upon receipt of a written order of the Trust signed by one
Administrative Trustee requesting the authentication and delivery of Definitive
Capital Securities to the Persons designated by the Trust, will authenticate and
make available for delivery Definitive Capital Securities, equal in number to
the number of Capital Securities represented by the Global Capital Security, in
exchange for such Global Capital Security.

                    pursuant to an effective registration statement under the
                    Securities Act or pursuant to Rule 144:

                        (A) in the case of any Restricted Capital Security that
                        is a Definitive Capital Security, the Registrar shall
                        permit the Holder thereof to exchange such Restricted
                        Capital Security for a Definitive Capital Security that
                        does not bear the Restricted Securities Legend and
                        rescind any restriction on the transfer of such
                        Restricted Capital Security; and

                        Registrar shall permit the Holder of such Global Capital
                        Security to exchange such Global Capital Security for
                        another Global Capital Security that does not bear the
                        Restricted Securities Legend.

                    (j) CANCELLATION OR ADJUSTMENT OF GLOBAL CAPITAL SECURITY.
At such time as all beneficial interests in the Global Capital Security have
either been exchanged for Definitive Capital Securities to the extent permitted
by this Declaration or redeemed, repurchased or canceled in accordance with the
terms of this Declaration, such Global Capital Security shall be returned to the
Clearing Agency for cancellation or retained and canceled by the Property
Trustee. At any time prior to such cancellation, if any beneficial interest in
the Global Capital Security is exchanged for Definitive Capital Securities,
Capital Securities represented by such Global Capital Security shall be reduced
and an adjustment shall be made on the books and records of the Property Trustee
and the Clearing Agency or its nominee to reflect such reduction.

                    (k) OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES OF
CAPITAL SECURITIES.

                        (i)  To permit registrations of transfers and

                    shall authenticate Definitive Capital Securities and the
                    Global Capital Security at the Registrar's or
                    co-registrar's request in accordance with the terms of this
                    Declaration.

                        (ii) Registrations of transfers or exchanges will be
                    effected without charge, but only upon payment (with such
                    indemnity as the Trust or the Sponsor

                        (iii) The Registrar or co-registrar shall not be
                    required to register the transfer of or exchange of (a)
                    Capital Securities during a period beginning at the opening
                    of business 15 days before the day of mailing of a notice
                    of redemption or any notice of selection of Capital
                    Securities for redemption and ending at the close of
                    business on the day of such mailing or (b) any Capital
                    Security so selected for redemption in whole or in part,
                    except the unredeemed portion of any Capital Security being
                    redeemed in part.

                        (iv) Prior to the due presentation for registration
                    of transfer of any Capital Security, the Trust, the
                    Property Trustee, the Paying Agent, the Registrar or any
                    co-registrar may deem and treat the Person in whose name a
                    Capital Security is registered as the absolute owner of
                    such Capital Security for the purpose of receiving
                    Distributions on such Capital Security and for all other
                    purposes whatsoever, and none of the Trust, the Property
                    Trustee, the Paying Agent, the Registrar or any
                    co-registrar shall be affected by notice to the contrary.

                        (v) All Capital Securities 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 Capital Securities surrendered upon
                    such registration of transfer or exchange.

                    (l) NO OBLIGATION OF THE PROPERTY TRUSTEE.

                        (i) The Property Trustee shall have no
                    responsibility or obligation to any Capital Security
                    Beneficial Owner, a Participant in the Clearing Agency or
                    other Person with respect to the accuracy of the records of
                    the Clearing Agency or its nominee or of any Participant
                    thereof, with respect to any ownership interest in the
                    Capital Securities or with respect to the delivery to any
                    Participant, beneficial owner or other Person (other than
                    the Clearing Agency) of any notice (including any notice of
                    redemption) or the payment of any amount, under or with
                    respect to such Capital Securities. All notices and
                    communications to be given to the Holders and all payments
                    to be made to Holders under the Capital Securities shall be
                    given or made only to or upon the order of the registered
                    Holders (which shall be the Clearing Agency or its nominee
                    in the case of the Global Capital Security). The rights of
                    Capital Security Beneficial Owners shall be exercised only
                    through the Clearing Agency subject to the applicable rules
                    and procedures of the Clearing Agency. The Property Trustee
                    may conclusively rely and shall be fully protected in
                    relying upon information furnished by the Clearing Agency
                    or any agent thereof with respect to its Participants and
                    any Capital Security Beneficial Owners.

                        (ii) The Property Trustee and the Registrar shall
                    have no obligation or duty to monitor, determine or
                    inquire as to compliance with any restrictions on

                    applicable law with respect to any transfer of any

                    between or among Clearing Agency Participants or Capital
                    Security Beneficial Owners) other than to require delivery
                    of such certificates and other documentation or evidence
                    as are expressly required by, and to do so if and when
                    expressly required by, the terms of this Declaration, and
                    to examine the same to determine substantial compliance as
                    to form with the express requirements hereof.

                    (m) EXCHANGE OF SERIES A CAPITAL SECURITIES FOR SERIES B
CAPITAL SECURITIES. The Series A Capital Securities shall be exchanged for
Series B Capital Securities pursuant to the terms of the Exchange Offer if the
following conditions are satisfied:

                    The Sponsor shall present the Property Trustee with an
Officers' Certificate certifying the following:

                    (A) upon issuance of the Series B Capital Securities, the
                    transactions contemplated by the Exchange Offer have been
                    consummated; and

                    (B) the number of Series A Capital Securities properly
                    tendered in the Exchange Offer that are represented by the
                    Global Capital Security and the number of Series A Capital
                    Securities properly tendered in the Exchange Offer that are
                    represented by Definitive Capital Securities, the name of
                    each Holder of such Definitive Capital Securities, the
                    liquidation amount of Capital Securities properly tendered
                    in the Exchange Offer by each such Holder and the name and
                    address to which Definitive Capital Securities for Series B
                    Capital Securities shall be registered and sent for each
                    such Holder.

                    The Property Trustee, upon receipt of (i) such Officers'
Certificate, (ii) an Opinion of Counsel (x) to the effect that the Series B
Capital Securities and the Series B Capital Securities Guarantee have been
registered under Section 5 of the Securities Act and that this Declaration and
the Series B Capital Securities Guarantee have been qualified under the Trust
Indenture Act and (y) with respect to the matters set forth in Section 3(q) of
the Registration Rights Agreement, shall authenticate (A) the Global Capital
Security, executed and delivered by the Trust to the Property Trustee, for
Series B Capital Securities in aggregate liquidation amount equal to the
aggregate liquidation amount of Series A Capital Securities represented by the
Global Capital Security indicated in such Officers' Certificate as having been
properly tendered and (B) Definitive Capital Securities, executed and delivered
by the Trust to the Property Trustee, representing Series B Capital Securities
registered in the names and in the liquidation amounts indicated in such
Officers' Certificate.

                    If, upon consummation of the Exchange Offer, less than all
the outstanding Series A Capital Securities shall have been properly tendered
and not withdrawn, the Property Trustee shall make an endorsement on the Global
Capital Security for Series A Capital Securities indicating the

                                       51

<PAGE>   58

reduction in the number and aggregate liquidation amount represented thereby as
a result of the Exchange Offer.

                    The Trust shall deliver such authenticated Definitive
Capital Securities for Series B Capital Securities to the Holders thereof as
indicated in such Officers' Certificate.

                    (n) MINIMUM TRANSFERS. Series A Capital Securities and, if
and when issued, Series B 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 Series A
Capital Securities or Series B Capital Securities in a block having an aggregate
liquidation amount of less than $100,000 shall be deemed to be voided and of no
legal effect whatsoever. Any such purported transferee shall be deemed not to be
a Holder of such Series A Capital Securities or Series B 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.

SECTION 9.3         DEEMED SECURITY HOLDERS.

                      The Trustees may treat the Person in whose name any
Security shall be registered on the books and records of the Trust as the sole
owner and Holder of such Security 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 Security on the
part of any Person, whether or not the Trust shall have actual or other notice
thereof.

SECTION 9.4         BOOK-ENTRY INTERESTS.

                    The Global Capital Security shall initially be registered on
the books and records of the Trust in the name of Cede & Co., the nominee of the
Clearing Agency and no Capital Security Beneficial Owner will receive physical
delivery of a definitive Capital Security certificate (a "Capital Security
Certificate") representing such Capital Security Beneficial Owner's interests in
such Global Capital Security, except as provided in Section 9.2 and Section 7.9.
Unless and until Definitive Capital Securities have been issued to the Capital
Security Beneficial Owners pursuant to Section 9.2 or Section 7.9:

                    (a) the provisions of this Section 9.4 shall be in full
force and effect;

                    (b) the Trust and the Trustees shall be entitled to deal
with the Clearing Agency for all purposes of this Declaration (including the
payment of Distributions on the Global Capital Security and receiving approvals,
votes or consents hereunder) as the sole Holder of the Global Capital Security
and shall have no obligation to the Capital Security Beneficial Owners;

                    (c) to the extent that the provisions of this Section 9.4
conflict with any other provisions of this Declaration, the provisions of this
Section 9.4 shall control; and

                    (d) the rights of the Capital Security Beneficial Owners
shall be exercised only through the Clearing Agency and shall be limited to
those established by law and agreements

                                       52

<PAGE>   59

between such Capital Security Beneficial Owners and the Clearing Agency and/or
the Clearing Agency Participants, and the Clearing Agency shall receive and
transmit payments of Distributions on the Global Capital Security to such
Clearing Agency Participants; PROVIDED, HOWEVER, that solely for the purposes of
determining whether the Holders of the requisite amount of Capital Securities
have voted on any matter provided for in this Declaration, the Trustees, with
respect to the Global Capital Security, may conclusively rely on, and shall be
protected in relying on, any written instrument (including a proxy) delivered to
the Trustees by the Clearing Agency setting forth the Capital Security
Beneficial Owners' votes or assigning the right to vote on any matter to any
other Persons either in whole or in part; and the Clearing Agency will also make
book-entry transfers among the Clearing Agency Participants.

SECTION 9.5         NOTICES TO CLEARING AGENCY.

                    Whenever a notice or other communication to the Capital
Security Holders is required to be given by a Trustee under this Declaration,
such Trustee shall give all such notices and communications specified herein to
be given to the Holder of the Global Capital Security to the Clearing Agency and
shall have no notice obligations to the Capital Security Beneficial Owners.

SECTION 9.6         APPOINTMENT OF SUCCESSOR CLEARING AGENCY.

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

                    HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1        LIABILITY.

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

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

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

                    (b) The Sponsor shall be liable for all of the debts and
obligations of the Trust (other than in respect of the Securities) to the extent
not satisfied out of the Trust's assets.

                    (c) Pursuant to section 3803(a) of the Business Trust Act,
the  Holders 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.

<PAGE>   60
SECTION 10.2        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 shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence (or in
the case of the Property Trustee or the Delaware Trustee, negligence) or willful
misconduct with respect to such acts or omissions.

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

SECTION 10.3        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 Property Trustee under the Trust Indenture
Act), are agreed by the parties hereto to replace such other duties and
liabilities of such Indemnified Person.

                    (b) Unless otherwise expressly provided herein:

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

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

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

                                       54

<PAGE>   61

Declaration or any other agreement contemplated herein or of any duty or
obligation of the Indemnified Person at law or in equity or otherwise.

                    (c) Whenever in this 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 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 10.4        INDEMNIFICATION.

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

                        (ii) The Sponsor shall indemnify, to the full extent
permitted by law, any Company Indemnified Person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Trust to procure a judgment in its favor by
reason of the fact that he is or was a Company Indemnified Person against
expenses (including attorneys' fees and expenses) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Trust and except that no such
indemnification shall be made in respect of any claim, issue or matter as to
which such Company 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.

                                       55

<PAGE>   62


                        (iii) To the extent that a Company 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 10.4(a), or in defense of any claim, issue or matter
therein, he shall be indemnified, to the full extent permitted by law, against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

                        (iv)  Any indemnification under paragraphs (i) and (ii)
of this Section 10.4(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 Company Indemnified Person is proper in the circumstances
because he has met the applicable standard of conduct set forth in paragraphs
(i) and (ii). Such determination shall be made (1) by the Administrative
Trustees by a majority vote of a Quorum consisting of such Administrative
Trustees who were not parties to such action, suit or proceeding, (2) if such a
Quorum is not obtainable, or, even if obtainable, if a Quorum of disinterested
Administrative Trustees so directs, by independent legal counsel in a written
opinion, or (3) by the Common Security Holder of the Trust.

                        (v) Expenses (including attorneys' fees and expenses)
incurred by a Company Indemnified Person in defending a civil, criminal,
administrative or investigative action, suit or proceeding referred to in
paragraphs (i) and (ii) of this Section 10.4(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 Company Indemnified Person to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Sponsor as authorized in this Section 10.4(a).
Notwithstanding the foregoing, no advance shall be made by the Sponsor if a
determination is reasonably and promptly made (i) by the Administrative Trustees
by a majority vote of a Quorum of disinterested Administrative Trustees, (ii) if
such a Quorum is not obtainable, or, even if obtainable, if a Quorum of
disinterested Administrative Trustees so directs, by independent legal counsel
in a written opinion or (iii) by the Common Security Holder of the Trust, that,
based upon the facts known to the Administrative Trustees, counsel or the Common
Security Holder at the time such determination is made, such Company Indemnified
Person acted in bad faith or in a manner that the Common Security Holder did not
believe to be in, or believed was opposed to, the best interests of the Trust,
or, with respect to any criminal proceeding, that such Company Indemnified
Person believed or had reasonable cause to believe his conduct was unlawful. In
no event shall any advance be made in instances where the Administrative
Trustees, independent legal counsel or Common Security Holder reasonably
determine that a Company Indemnified Person deliberately breached his duty to
the Trust or its Common or Capital Security Holders.

                        (vi)  The indemnification and advancement of expenses
provided by, or granted pursuant to, the other paragraphs of this Section
10.4(a) shall not be deemed exclusive of any other rights to which those seeking
indemnification and advancement of expenses may be entitled under any agreement,
vote of stockholders or disinterested directors of the Sponsor or Capital
Security Holders of the Trust or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office. All
rights to indemnification under this Section 10.4(a) shall be deemed to be
provided by a contract between the Sponsor and each Company Indemnified Person
who serves in such capacity at any time while this Section 10.4(a) is

                                       56

<PAGE>   63

in effect. Any repeal or modification of this Section 10.4(a) shall not affect
any rights or obligations then existing.

                        (vii) The Sponsor or the Trust may purchase and maintain
insurance on behalf of any person who is or was a Company Indemnified Person
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the Debenture
Issuer would have the power to indemnify him against such liability under the
provisions of this Section 10.4(a).

                        (viii) For purposes of this Section 10.4(a), references
to "the Trust" shall include, in addition to the resulting or surviving entity,
any constituent entity (including any constituent of a constituent) absorbed in
a consolidation or merger, so that any person who is or was a director, trustee,
officer or employee of such constituent entity, or is or was serving at the
request of such constituent entity as a director, trustee, officer, employee or
agent of another entity, shall stand in the same position under the provisions
of this Section 10.4(a) with respect to the resulting or surviving entity as he
would have with respect to such constituent entity if its separate existence had
continued.

                        (ix) The indemnification and advancement of expenses
provided by, or granted pursuant to, this Section 10.4(a) shall, unless
otherwise provided when authorized or ratified, continue as to a Person who has
ceased to be a Company Indemnified Person and shall inure to the benefit of the
heirs, executors and administrators of such a Person.

                    (b) The Sponsor agrees to indemnify the (i) Property
Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Property Trustee
or the Delaware Trustee, and (iv) any officers, directors, shareholders,
members, partners, employees, representatives, custodians, nominees or agents of
the Property Trustee or the Delaware Trustee (each of the Persons in (i) through
(iv), including the Property Trustee and the Delaware Trustee in their
respective individual capacities, being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any and all loss, liability, damage, action, suit, claim or expense including
taxes (other than taxes based on the income of such Fiduciary Indemnified
Person) of any kind and nature whatsoever incurred without negligence or bad
faith on the part of such Fiduciary Indemnified Person, arising out of or in
connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses (including reasonable legal fees and
expenses) of defending against or investigating any claim or liability in
connection with the exercise or performance of any of the powers or duties of
such Fiduciary Indemnified Person hereunder. The obligation to indemnify as set
forth in this Section 10.4(b) shall survive the resignation or removal of the
Property Trustee or the Delaware Trustee and the satisfaction and discharge of
this Declaration.

                    (c) The Sponsor agrees to pay the Property Trustee and the
Delaware Trustee, from time to time, such compensation for all services rendered
by the Property Trustee and the Dela ware Trustee hereunder as may be mutually
agreed upon in writing by the Sponsor and the Property Trustee or the Delaware
Trustee, as the case may be, and, except as otherwise expressly provided herein,
to reimburse the Property Trustee and the Delaware Trustee upon its or their
request for all reasonable expenses (including legal fees and expenses),
disbursements and advances incurred or

                                       57

<PAGE>   64


made by the Property Trustee or the Delaware Trustee, as the case may be, in
accordance with the provisions of this Declaration, except any such expense,
disbursement or advance as may be attributable to its or their negligence or bad
faith.

SECTION 10.5        OUTSIDE BUSINESSES.

                    Any Covered Person, the Sponsor, the Delaware Trustee and
the Property Trustee (subject to Section 5.3(c)) may engage in or possess an
interest in other business ventures of any nature or description, independently
or with others, similar or dissimilar to the business of the Trust, and the
Trust and the Holders shall have no rights by virtue of this 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. No Covered Person, the Sponsor, the
Delaware Trustee, or the Property Trustee shall be obligated to present any
particular investment or other opportunity to the Trust even if such opportunity
is of a character that, if presented to the Trust, could be taken by the Trust,
and any Covered Person, the Sponsor, the Delaware Trustee and the Property
Trustee shall have the right to take for its own account (individually or as a
partner or fiduciary) or to recommend to others any such particular investment
or other opportunity. Any Covered Person, the Delaware Trustee and the Property
Trustee may engage or be interested in any financial or other transaction with
the Sponsor or any Affiliate of the Sponsor, or may act as depositary for,
trustee or agent for, or act on any committee or body of holders of, securities
or other obligations of the Sponsor or its Affiliates.

SECTION 11.1        FISCAL YEAR.

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

SECTION 11.2        CERTAIN ACCOUNTING MATTERS.

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

                    (b) The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders any 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

                                       58

<PAGE>   65

deliver any such statement at a later date, the Administrative Trustees shall
endeavor to deliver all such information statements within 30 days after the end
of each Fiscal Year of the Trust.

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

SECTION 11.3        BANKING.

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

SECTION 11.4        WITHHOLDING.

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

PROVIDED, HOWEVER, that the Property Trustee shall not be required to sign any
such amendment; and

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

                            (A) cause the Trust to fail to continue to be
                            classified for purposes of United States federal
                            income taxation as a grantor trust;

                    times that any Securities are outstanding or to ensure

such amendments of this Declaration shall become effective when notice thereof

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. The
Administrative Trustees shall call a meeting of the Holders of such class if
directed to do so by the Holders of at least 20% in Liquidation Amount of such
class of Securities. Such direction shall be given by delivering to the
Administrative Trustees one or more notices in writing stating that the signing
Holders wish to call a meeting and indicating the general or specific purpose
for which the meeting is to be called. Any Holders calling a meeting shall
specify in writing the Capital Security Certificates held by the Holders
exercising the right to

                                       61

of determining whether the required percentage set forth in the second sentence

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

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

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

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

                        (iv) unless the Business 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 or
                    trading, otherwise provides, the Administrative Trustees,
                    in their sole discretion, shall establish all other
                    provisions relating to meetings of Holders, including
                    notice of the time, place or purpose of any meeting at
                    which any matter is to be voted on by any Holders, waiver
                    of any such notice, action by consent without a meeting,

                                     ANNEX I

                                    TERMS OF
                  9.875% CAPITAL SECURITIES, SERIES A/SERIES B
                            9.875% COMMON SECURITIES


                  Pursuant to Section 7.1 of the Amended and Restated
Declaration, dated as of October 18, 1999 (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Securities are set out below (each
capitalized term used but not defined herein has the meaning set forth in the
Declaration or, if not defined in such Declaration, as defined in the Offering
Memorandum referred to below in Section 2(c) of this Annex I):

         1.  DESIGNATION AND NUMBER.

         (a) CAPITAL SECURITIES. 20,000 Series A Capital Securities of the Trust
and 20,000 Series B Capital Securities of the Trust, each series with an
aggregate liquidation amount with respect to the assets of the Trust of Twenty
Million Dollars ($20,000,000) and with a liquidation amount with respect to the
assets of the Trust of One Thousand Dollars ($1,000) (the "Liquidation Amount")
per security, are hereby designated for the purposes of identification only as "
9.875% Capital Securities, Series A" and " 9.875% Capital Securities, Series B,"
respectively (collectively, the "Capital Securities"). The certificates
evidencing the Capital Securities shall be substantially in the form of Exhibit
A-1 to the Declaration, with such changes and additions thereto or deletions
therefrom as may be required by ordinary usage, custom or practice or to conform
to the rules of any exchange or quotation system on or in which the Capital
Securities are listed, traded or quoted.

         (b) COMMON SECURITIES. 619 Common Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of Six
Hundred Nineteen Thousand Dollars ($619,000) and a liquidation amount with
respect to the assets of the Trust of $1,000 per security, are hereby designated
for the purposes of identification only as " 9.875% Common Securities" (the
"Common Securities"). The certificates evidencing the Common Securities shall be
substantially in the form of Exhibit A-2 to the Declaration, with such changes
and additions thereto or deletions therefrom as may be required by ordinary
usage, custom or practice.

         2.  DISTRIBUTIONS.

         (a) Distributions on each Security will be payable at a fixed rate per
annum of 9.875% (the "Coupon Rate") of the liquidation amount of $1000 per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Property Trustee. Distributions in arrears for more than one
semi-annual period will bear additional Distributions thereon compounded semi-
annually at the Coupon Rate (to the extent permitted by applicable law).
Pursuant to the Registration Rights Agreement and the Liquidated Damages
Agreement, in certain limited circumstances the Debenture Issuer will be
required to pay Liquidated Damages (as defined in the Registration Rights
Agreement) with respect to the Debentures. The term "Distributions" as used
herein, includes distributions of any and all such interest and Liquidated
Damages, if any, payable unless otherwise

                                       I-1

<PAGE>   75

stated. A Distribution is payable only to the extent that payments are made with
respect to the Debentures held by the Property Trustee and to the extent the
Property Trustee has funds legally available therefor.

         (b) Distributions on the Securities will be cumulative, will accumulate
from the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from October 18, 1999 and will be payable
semi-annually in arrears on April 15 and October 15 of each year, commencing
April 15, 2000 (each, a "Distribution Date"), except as otherwise described
below. Distributions will be computed on the basis a 360-day year of twelve
30-day months. As long as no Event of Default has occurred and is continuing
under the Indenture, the Debenture Issuer has the right under the Indenture to
defer payments of interest by extending the interest payment period at any time
and from time to time on the Debentures for a period not exceeding 10
consecutive semi-annual periods, including the first such semi-annual period
during such period (each an "Extension Period"), during which Extension Period
no interest shall be due and payable on the Debentures, PROVIDED THAT no
Extension Period shall end on a date other than an Interest Payment Date for the
Debentures or extend beyond the Maturity Date of the Debentures. As a
consequence of such deferral, Distributions (other than Liquidated Damages, if
any) will also be deferred. Notwithstanding such deferral, Distributions will
continue to accumulate with additional Distributions thereon (to the extent
permitted by applicable law but not at a rate greater than the rate at which
interest is then accruing on the Debentures) at the Coupon Rate compounded
semi-annually during any such Extension Period. Prior to the termination of any
such Extension Period, the Debenture Issuer may further defer payments of
interest by further extending such Extension Period, PROVIDED THAT such
extension does not cause such Extension Period, together with all such previous
and further extensions within such Extension Period, to exceed 10 consecutive
semi-annual periods, including the first semi-annual period during such
Extension Period, end on a date other than an Interest Payment Date for the
Debentures or extend beyond the Maturity Date of the Debentures. Upon the
termination of any Extension Period and the payment of all amounts then due, the
Debenture Issuer may commence a new Extension Period, subject to the above
requirements.

         (c) Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the close of
business on the first day of the month in which relevant the Distribution Date
occurs, which Distribution Dates correspond to the Interest Payment Dates for
the Debentures. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment with respect to the Capital
Securities will be made as described under the heading "Description of Capital
Securities--Form, Denomination, Book-Entry Procedures and Transfer" in the
Offering Memorandum dated October 13, 1999 of the Debenture Issuer and the Trust
relating to the Securities and the Debentures. The relevant record dates for the
Common Securities shall be the same as the record dates for the Capital
Securities. Distributions payable on any Securities that are not punctually paid
on any Distribution Date, as a result of the Debenture Issuer having failed to
make a payment under the Debentures, will cease to be payable to the Holder 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 deter mined in accordance with the
Indenture. If any date on which Distributions are payable on the Securities is
not a Business Day, then payment of the Distributions payable on such date will
be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay), except that if such
next succeeding Business Day falls in the next

                                       I-2

<PAGE>   76

succeeding calendar year, such payment shall be made on the immediately
preceding Business Day with the same force and effect as if made on such date.

         (d) 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.

         3.  LIQUIDATION DISTRIBUTION UPON DISSOLUTION.

             In the event of any dissolution of the Trust, the Trust shall
be liquidated by the Administrative Trustees as expeditiously as the
Administrative Trustees determine to be possible by distributing to the Holders,
after satisfaction of liabilities to creditors of the Trust as provided by
applicable law, a Like Amount (as defined below) of the Debentures, unless such
distribution is determined by the Property Trustee not to be practicable, in
which event such Holders will be entitled to receive out of the assets of the
Trust legally available for distribution to Holders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, an amount
equal to the aggregate of the liquidation amount of $1,000 per Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution").

             "Like Amount" means (i) with respect to a redemption of the
Securities, Securities having a Liquidation Amount equal to the principal amount
of Debentures to be paid in accordance with their terms and (ii) with respect to
a distribution of Debentures upon the liquidation of the Trust, Debentures
having a principal amount equal to the Liquidation Amount of the Securities of
the Holder to whom such Debentures are distributed.

             If, upon any such liquidation, the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets legally
available to pay in full the aggregate Liquidation Distribution, then the
amounts payable directly by the Trust with respect to the Securities shall be
paid on a Pro Rata basis.

         4.  REDEMPTION AND DISTRIBUTION.

         (a) Upon the repayment of the Debentures (with premium, if any) in
whole or in part, at maturity or otherwise (either at the option of the
Debenture Issuer or pursuant to a Special Event, as described below), the
proceeds from such repayment shall be simultaneously applied by the Property
Trustee (subject to the Property Trustee having received written notice no later
than 45 days prior to such repayment) to redeem a Like Amount of the Securities
at a redemption price equal to (i) in the case of the repayment of the
Debentures on the Maturity Date, the Maturity Redemption Price (as defined
below), (ii) in the case of the optional prepayment of the Debentures prior to
the Initial Optional Redemption Date and upon the occurrence and continuation of
a Special Event, the Special Event Redemption Price (as defined below) and (iii)
in the case of the optional prepayment of the Debentures on or after the Initial
Optional Redemption Date, the Optional Redemption Price (as defined below). The
Maturity Redemption Price, the Special Event Redemption Price and the Optional
Redemption Price are referred to collectively as the "Redemption Price". Holders
will be given not less than 30 nor more than 60 days prior written notice of
such redemption.


                                       I-3

<PAGE>   77

         (b) (i) The "Maturity Redemption Price" shall mean an amount equal to
100% of the principal of, plus accrued and unpaid interest (including Compounded
Interest and Additional Sums, if any, thereon to the date of redemption) on, the
Debentures as of the Maturity Date thereof.

                 (ii)  The Debenture Issuer shall have the right (subject to the
conditions in the Indenture) to elect to redeem the Debentures, in whole or in
part, at any time on or after October 15, 2009 (the "Initial Optional Redemption
Date"), and, simultaneous with such redemption, to cause a Like Amount of the
Securities to be redeemed by the Trust at the Optional Redemption Price on a Pro
Rata basis. "Optional Redemption Price" shall mean an amount equal to the
applicable redemption price set forth below plus, accumulated and unpaid
Distributions thereon, if any, to the date of such redemption if redeemed during
the 12-month period beginning October 15, of the years indicated below:


                                            Percentage of
               Year                      Liquidation Amount
       --------------------------   ------------------------------
           2009                               104.938%
           2010                               104.444%
           2011                               103.950%
           2012                               103.457%

           2014                               102.469%
           2015                               101.975%
           2016                               101.481%
           2017                               100.988%
           2018                               100.494%
           2019 and thereafter                100.000%

         (c) If at any time an Investment Company Event, a Regulatory Capital
Event or a Tax Event (each as defined below, and each a "Special Event") occurs,
the Debenture Issuer shall have the right (subject to the conditions set forth
in the Indenture) at any time prior to the Initial Optional Redemption Date, to
redeem the Debentures in whole, but not in part, within the 90 days following
the occurrence of such Special Event (the "90 Day Period"), and, simultaneous
with such redemption, to cause a Like Amount of the Securities to be redeemed by
the Trust at the Redemption Price on a Pro Rata basis.

             "Investment Company Event" shall mean the receipt by the
Debenture Issuer and the Trust of an opinion of independent securities counsel
experienced in such matters to the effect that

                                       I-4

<PAGE>   78

as a result of (a) any amendment to, or change (including any announced
prospective change) in, the laws or any regulations thereunder of the United
States or any rules, guidelines or policies of any applicable regulatory
authority for the Debenture Issuer or (b) any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or which pronouncement or
decision is announced on or after the date of original issuance of the
Securities, 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.

             "Regulatory Capital Event" shall mean the receipt by the
Debenture Issuer and the Trust of an opinion of independent bank regulatory
counsel experienced in such matters to the effect that as a result of (a) any
amendment to, or change (including any announced prospective change) in, the
laws or any regulations thereunder of the United States or any rules, guidelines
or policies of an applicable regulatory authority for the Debenture Issuer or
(b) any official administrative pronouncement or judicial decision interpreting
or applying such laws or regulations, which amendment or change is effective or
which pronouncement or decision is announced on or after the date of original
issuance of the Securities, the Capital Securities do not constitute, or within
90 days of the date of such opinion will not constitute, Tier 1 Capital (or its
then equivalent if the Sponsor were subject to such capital requirement);
PROVIDED, 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 Regulatory Capital Event.

             "Special Event Prepayment Price" shall mean, with respect to
any redemption of the Securities following a Special Event, an amount in cash
equal to the greater of (i) 100% of the principal amount of the Securities to be
prepaid or (ii) the sum, as determined by a Quotation Agent, of the present
values of the remaining scheduled payments of principal and interest on such
Securities, discounted to the prepayment date on a sem-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate,
plus, in the case of (i) or (ii), any accrued and unpaid interest thereon
(including Compounded Interest and Additional Sums, if any) to the date of such
prepayment.

             A "Tax Event" shall occur upon receipt by the Debenture Issuer
and the Trust of an opinion of independent tax counsel experienced in such
matters to the effect that, as a result of (a) 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 (b) any official administrative pronouncement or judicial
decision interpreting or applying such laws or regulations, which amendment or
change is effective or which pronouncement or decision is announced on or after
the date of original issuance of the Securities, 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) the 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, duties or other governmental charges.


                                       I-5

<PAGE>   79

         (d) In the case of an optional redemption, if fewer than all the
outstanding Securities are to be so redeemed, the Common Securities and the
Capital Securities shall be redeemed Pro Rata and the Capital Securities to be
redeemed will be determined as described in Section 4(f)(ii) below. Upon the
entry of an order for the dissolution of the Trust by a court of competent
jurisdiction, the Debentures thereafter will be subject to optional redemption,
in whole, but not in part, on or after the Initial Optional Redemption Date.

         (e) On and from the date fixed by the Trustees for any distribution of
Debentures and liquidation of the Trust: (i) the Securities will no longer be
deemed to be outstanding, (ii) the Clearing Agency or its nominee (or any
successor Clearing Agency or its nominee), as the Holder of the Capital
Securities, will receive a registered global certificate or certificates
representing the Debentures to be delivered upon such distribution, and (iii)
any certificates representing Securities not held by the Clearing Agency or its
nominee (or any successor Clearing Agency or its nominee) will be deemed to
represent beneficial interests in a Like Amount of Debentures until such
certificates are presented to the Debenture Issuer or its agent for transfer or
reissue.

         (f) The Trust may not redeem fewer than all the outstanding Securities
unless all accumulated and unpaid Distributions have been paid on all Securities
for all semi-annual Distribution periods terminating on or before the date of
redemption.

         (g) The procedure with respect to redemptions or distributions of
Securities shall be as follows:

             (i) Notice of any redemption of, or notice of distribution of
         Debentures in exchange for, the Securities (a "Redemption/Distribution
         Notice") will be given by the Trust by mail to each Holder 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(f)(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. Each Redemption/Distribution Notice shall be
         addressed to the Holders at the address of each such Holder appearing
         in the books and records of the Trust. No defect in the
         Redemption/Distribution Notice or in the mailing of either thereof with
         respect to any Holder shall affect the validity of the redemption or
         exchange proceedings with respect to any other Holder.

             (ii) In the event that fewer than all the outstanding
         Securities are to be redeemed, the particular Securities to be redeemed
         shall be selected on a Pro Rata basis (based upon Liquidation Amounts)
         not more than 60 nor less than 30 days prior to the date fixed for
         redemption from the outstanding Securities not previously called for
         redemption; PROVIDED, HOWEVER, that with respect to Holders that would
         be required to hold less than 100 but more than zero Securities as a
         result of such redemption, the Trust shall redeem Securities of each
         such Holder so that after such redemption such Holder shall hold either
         100 Securities or such Holder no longer holds any Securities, and shall
         use such method (including, without limitation, by lot) as the Trust
         shall deem fair and appropriate; PROVIDED, FURTHER, that any

                                       I-6

<PAGE>   80

         such redemption may be made on the basis of the aggregate Liquidation
         Amount of Securities held by each Holder thereof and may be made by
         making such adjustments as the Trust deems fair and appropriate in
         order that fractional Securities shall not thereafter remain
         outstanding. With respect to Capital Securities registered in the name
         of and held of record by the Clearing Agency or its nominee (or any
         successor Clearing Agency or its nominee) or any nominee, the
         distribution of the proceeds of such redemption will be made to the
         Clearing Agency and disbursed by such Clearing Agency in accordance
         with the procedures applied by such agency or nominee.

             (iii) If Securities are to be redeemed and the Trust gives a
         Redemption/ Distribution Notice (which notice will be irrevocable),
         then (A) with respect to Capital Securities issued in book-entry form,
         by 12:00 noon, New York City time, on the redemption date, PROVIDED
         THAT the Debenture Issuer has paid the Property Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Debentures by 10:00 a.m., New York City time, on the Maturity Date
         or the date of redemption, as the case re quires, the Property Trustee
         will deposit irrevocably with the Clearing Agency or its nominee (or
         successor Clearing Agency or its nominee) immediately available funds
         sufficient to pay the applicable Redemption Price with respect to such
         Capital Securities and will give the Clearing Agency irrevocable
         instructions and authority to pay the Redemption Price to the relevant
         Clearing Agency Participants, and (B) with respect to Capital
         Securities issued in certificated form and Common Securities, PROVIDED
         THAT the Debenture Issuer has paid the Property Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Debentures, the Property Trustee will irrevocably deposit with the
         paying agent for the Capital Securities (if other than the Property
         Trustee) funds sufficient to pay the applicable Redemption Price to the
         Holders by check mailed to the address of the relevant Holder appearing
         on the books and records of the Trust on the redemption date, and
         PROVIDED FURTHER, that any such payment shall become due only upon
         surrender by the Holder of the related certificated Capital Securities.
         If a Redemption/ Distribution Notice shall have been given and funds
         deposited as required, if applicable, then immediately prior to the
         close of business on the date of such deposit, or on the redemption
         date, as applicable, Distributions will cease to accumulate on the
         Securities so called for redemption and all rights of Holders so called
         for redemption will cease, except the right of the Holders of such
         Securities to receive the Redemption Price, but without interest on
         such Redemption Price, and such Securities shall cease to be
         outstanding.

             (iv) Payment of accumulated and unpaid Distributions on the
         Redemption Date of the Securities will be subject to the rights of
         Holders at the close of business on a regular record date in respect of
         a Distribution Date occurring on or prior to such Redemption Date.

             Neither the Administrative Trustees nor the Trust shall be
required to register or cause to be registered the transfer of (i) any
Securities beginning at the opening of business 15 days before the day of
mailing of a notice of redemption or any notice of selection of Securities for
redemption or (ii) any Securities selected for redemption, except the unredeemed
portion of any Security being redeemed. If any date fixed for redemption of
Securities is not a Business Day, then payment of the Redemption Price payable
on such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay). If payment
of the Re-

                                      I-7
<PAGE>   81

demption Price with respect to any Securities is improperly withheld or refused
and not paid either by the Property Trustee or by the Sponsor as guarantor
pursuant to the relevant Securities Guarantee, Distributions on such Securities
will continue to accumulate 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.

             (v) Redemption/Distribution Notices shall be sent by the
         Property Trustee on behalf of the Trust to (A) with respect to Capital
         Securities issued in book-entry form, the Clearing Agency or its
         nominee (or any successor Clearing Agency or its nominee), (B) with
         respect to Capital Securities issued in certificated form, to the
         Holders thereof, and (C) with respect to the Common Securities, to the
         Holders thereof.

             (vi) Subject to the foregoing and applicable law (including,
         without limitation, United States federal securities laws and banking
         laws), the Sponsor or any of its subsidiaries may at any time and from
         time to time purchase outstanding 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), 6(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Capital Securities will
have no voting rights.

         (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee or executing any
trust or power conferred on such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.07 of
the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures or (iv) consent
to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in Liquidation Amount
of all outstanding Capital Securities; PROVIDED, HOWEVER, that where a consent
under the Indenture would require the consent of each holder of Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior approval of each Holder of the Capital Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of the Capital Securities except by subsequent vote of such Holders. The
Property Trustee shall notify each Holder of Capital Securities of any notice of
default with respect to the Debentures. In addition to obtaining the foregoing
approvals of such Holders of the Capital Securities, prior to taking any of the
foregoing actions, the Trustees shall obtain an opinion of counsel experienced
in such matters to the effect that the Trust will continue to be classified as a
grantor trust for United States federal income tax purposes after taking any
such action into account.

             If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
the due date (or, in the case of redemption, on the redemption date), then a
Holder of Capital Securities may institute a proceeding directly against the
Debenture Issuer for enforcement of payment to such Holder of the principal of
or interest on a Like Amount of

                                       I-8

<PAGE>   82

Debentures (a "Direct Action") on or after the respective due date specified in
the Debentures. In connection with such Direct Action, the Common Securities
Holder will be subrogated to the rights of such Holder of Capital Securities to
the extent of any payment made by the Debenture Issuer to such Holder of Capital
Securities in such Direct Action. Except as provided in the second preceding
sentence, or except as set forth in the first sentence of Section 3.8(e) of the
Declaration, the Holders of Capital Securities will not be able to exercise
directly any other remedy available to the holders of the Debentures.

             Any approval or direction of Holders of Capital Securities may
be given at a separate meeting of Holders of Capital Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Property Trustee will cause a notice of any
meeting at which Holders of Capital Securities are entitled to vote to be mailed
to each Holder of record of Capital Securities. Each such notice will include a
statement setting forth (i) the date of such meeting 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 consent.

             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 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 be entitled to vote or consent and shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

         6.  VOTING RIGHTS - COMMON SECURITIES.

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

         (b) Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by the Holder of the Common
Securities. If a Debenture Event of Default has occurred and is continuing, the
Property Trustee and the Delaware Trustee may be removed at such time by the
Holders of a Majority in Liquidation Amount of the outstanding Capital
Securities. In no event will the Holders of the Capital Securities have the
right to vote to appoint, remove or replace the Administrative Trustees, which
voting rights are vested exclusively in the Sponsor as the Holder of the Common
Securities. No resignation or removal of a Trustee and no appointment of a
successor trustee shall be effective until the acceptance of appointment by the
successor trustee in accordance with the provisions of the Declaration.

         (c) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.07 of
the Indenture,

                                       I-9

<PAGE>   83

(iii) exercise any right to rescind or annul a declaration of acceleration of
the maturity of the principal of the Debentures or (iv) consent to any
amendment, modification or termination of the Indenture or the Debentures, where
such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of a Majority in Liquidation Amount of all outstanding
Common Securities; PROVIDED, HOWEVER, that where a consent under the Indenture
would require the consent of each holder of Debentures affected thereby, no such
consent shall be given by the Property Trustee without the prior approval of
each Holder of the Common Securities. The Trustees shall not revoke any action
previously authorized or approved by a vote of the Holders of the Common
Securities except by subsequent vote of such Holders. The Property Trustee shall
notify each Holder of Common Securities of any notice of default with respect to
the Debentures. In addition to obtaining the foregoing approvals of such Holders
of the Common Securities, prior to taking any of the foregoing actions, the
Trustees shall obtain an opinion of counsel experienced in such matters to the
effect that the Trust will continue to be classified as a grantor trust for
United States federal income tax purposes after taking any such action into
account.

             If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
the due date (or in the case of redemption, on the redemption date), then a
Holder of Common Securities may institute a Direct Action directly against the
Debenture Issuer for enforcement of payment to such Holder of the principal of
or premium, if any, or interest on a Like Amount of Debentures on or after the
respective due date specified in the Debentures. In connection with such Direct
Action, the rights of the Common Securities Holder will be subordinated to the
rights of Holders of Capital Securities in respect of any payment from the
Debenture Issuer in such Direct Action. Except as provided in the second
preceding sentence, the Holders of Common Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures.

             Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Administrative Trustees will cause a notice of
any meeting at which Holders of Common Securities are entitled to vote, 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 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.

             In addition to the requirements set out in Section 12.1 of the
Declaration, the Declaration may be amended from time to time by the Sponsor,
the Property Trustee and the Administrative Trustees without the consent of the
Holders to (i) cure any ambiguity, correct or supplement any provisions in the
Declaration that may be inconsistent with any other provisions, or make any
other provisions with respect to matters or questions arising under the
Declaration which shall not be inconsistent with the other provisions of the
Declaration, (ii) modify, eliminate or add to any provisions of the Declaration
to such extent as shall be necessary to ensure that the Trust will be classified
for United States federal income tax purposes as a grantor trust at all times
that any Securities are outstanding or to ensure that the Trust will not be
required to register as an Investment Company under the Investment Company Act
or (iii) modify, eliminate or add any provisions of the Declaration to such
extent as shall be necessary to enable the Trust or the Sponsor to conduct an
Exchange Offer in the manner contemplated by the Registration Rights Agreement;
PROVIDED, HOWEVER, that in each case, such action shall not adversely affect in
any material respect the interests of any Holder, and any such amendments of the
Declaration shall become effective when notice thereof is given to the Holders.
The Declaration may also be amended by the Trustees and the Sponsor with (i) the
consent of Holders representing a Majority in Liquidation Amount of all
outstanding Securities, and (ii) receipt by the Trustees of an Opinion of
Counsel to the effect that such amendment or the exercise of any power granted
to the Trustees in accordance with such amendment will not affect the Trust's
status as a grantor trust for United States federal income tax purposes or the
Trust's exemption from status as an Investment Company under the Investment
Company Act; PROVIDED, HOWEVER, that, without the consent of each Holder of
Trust Securities, the Declaration may not be amended to (i) change the amount or
timing of any Distribution on, or the payment required to be made in respect of,
the Trust Securities as of a specified date or (ii) restrict the right of a
Holder of Trust Securities to institute suit for the enforcement of any such
payment on or after such date.

         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
according to the aggregate liquidation amount of the Securities held by such
Holder in relation to the aggregate liquidation amount of all Securities
outstanding unless, in relation to a payment, an Event of Default under the
Declaration 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 Capital Securities
held by such Holder relative to the aggregate liquidation amount of all Capital
Securities outstanding and then, only after satisfaction of all amounts owed to
the Holders of the Capital Securities, to each Holder of Common Securities pro
rata according to the aggregate liquidation amount of Common Securities held by
such Holder relative to the aggregate liquidation amount of all Common
Securities outstanding.

         9.  RANKING.

             The Capital Securities rank PARI PASSU with the Common
Securities and payment thereon shall be made Pro Rata with the Common
Securities, except that, if an Event of Default under the Declaration occurs and
is continuing, no payments in respect of Distributions on, or payments upon
liquidation, redemption or otherwise with respect to, the Common Securities
shall be made until the Holders of the Capital Securities shall be paid in full
the Distributions, Redemption Price, Liquidation Distribution and any other
payments to which they are entitled at such time.

         10. ACCEPTANCE OF CAPITAL SECURITIES GUARANTEE, COMMON SECURITIES
             GUARANTEE.

the acceptance thereof, agrees to the provisions of the Capital Securities
Guarantee, the Common Securities Guarantee, the Indenture and the Debentures, as
applicable, including the subordination provisions therein.

         11. NO PREEMPTIVE RIGHTS.

             Neither the issuance of Capital Securities, nor the issuance
of Common Securities is subject to preemptive or other similar rights. The
Holders shall have no 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

                          [FORM OF REVERSE OF SECURITY]


                  Distributions on each Capital Security will be payable at a
fixed rate per annum of 9.875% (the "Coupon Rate") of the liquidation amount of
$1000 per Capital Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one semi-annual period will bear interest thereon compounded semi-annually
at the Coupon Rate (to the extent permitted by applicable law). Pursuant to the
Registration Rights Agreement and the Liquidated Damages Agreement, in certain
limited circumstances the Debenture Issuer will be required to pay Liquidated
Damages (as defined in the Registration Rights Agreement) with respect to the
Debentures. The term "Distributions," as used herein, includes such cash
distributions and any and all such interest and Liquidated Damages, if any,
payable unless otherwise stated. A Distribution is payable only to the extent
that payments are made in respect of the Debentures held by the Property Trustee
and to the extent the Property Trustee has funds legally available therefor.

                  Distributions on the Capital Securities will be cumulative,
will accumulate from the most recent date to which Distributions have been paid
or, if no Distributions have been paid, from October 18, 1999 and will be
payable semi-annually in arrears, on April 15 and October 15 of each year,
commencing April 15, 2000, except as otherwise described below. Distributions
will be computed on the basis of a 360-day year of twelve 30-day months. As long
as no Event of Default has occurred and is continuing under the Indenture, the
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period at any time and from time to time on
the Debentures for a period not exceeding 10 consecutive semi-annual calendar
periods, including the first such semi-annual period during such extension
period (each an "Extension Period"), PROVIDED THAT no Extension Period shall end
on a date other than an Interest Payment Date for the Debentures or extend
beyond the Maturity Date of the Debentures. As a consequence of such deferral,
Distributions (other than Liquidated Damages, if any) will also be deferred.
Notwithstanding such deferral, semi-annual Distributions will continue to
accumulate with interest thereon (to the extent permitted by applicable law, but
not at a rate exceeding the rate of interest then accruing on the Debentures) at
the Coupon Rate compounded semi-annually during any such Extension Period. Prior
to the termination of any Extension Period, the Debenture Issuer may further
defer payments of interest by further extending such Extension Period; PROVIDED
THAT such Extension Period, together with all such previous and further
extensions within such Extension Period, may not (i) exceed 10 consecutive
semi-annual periods, including the first semi-annual period during such
Extension Period, (ii) end on a date other than an Interest Payment Date for the
Debentures or (iii) extend beyond the Maturity Date of the Debentures. Payments
of accumulated Distributions will be payable to Holders as they appear on the
books and records of the Trust on the record date immediately preceding the end
of the Extension Period. Upon the termination of any Extension Period and the
payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

                  Subject to receipt by the Sponsor of any and all required
regulatory approvals and to certain other conditions set forth in the
Declaration and the Indenture, the Property Trustee may, at the direction of the
Sponsor, at any time dissolve the Trust and after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, cause the Debentures to be
distributed to the

any redemption of the Debentures, cause a Like Amount of the Securities to be

Declaration.

             (2), (3) or (7) of Rule 501 under the Securities Act
             of 1933 that is acquiring the Capital Securities for
             its own account, or for the account of such an
             institutional "accredited investor," for investment
             purposes and not with a view to, or for offer or sale
             in connection with, any distribution in violation of
             the Securities Act of 1933, as amended; or

   (4)  [ ]  transferred pursuant to another available exemption from the
             registration requirements of the Securities Act of 1933, as
             amended; or

   (5)  [ ]  transferred pursuant to an effective registration statement.

Unless one of the boxes is checked, the Registrar will refuse to register any of
the Capital Securities evidenced by this Certificate in the name of any Person
other than the Holder hereof; PROVIDED, HOWEVER, that if box (3) or (4) is
checked, the Registrar may require, prior to registering any such transfer of
the Capital Securities, such legal opinions, certifications and other
information as the Trust has reasonably requested to confirm that such transfer
is being made pursuant to an exemption from, or in a transaction not subject to,
the registration requirements of the Securities Act of 1933, as amended, such as
the exemption provided by Rule 144 under such Act; PROVIDED, FURTHER, that (i)
if box (2) is checked, by acceptance of this Certificate, the transferee shall
be deemed to have certified that it is a "qualified institutional buyer" (as
defined in Rule 144A) ("QIB") acquiring the Capital Securities for its own
account or for the account of another QIB over which it exercises sole
investment discretion and that it is aware that the Holder is relying upon the
exemption from registration afforded by Rule 144A in respect of the Holder's
transfer of Capital Securities to it or (ii) if box (3) is checked, the
transferee must also provide to the Registrar a Transferee Letter of
Representation in the form attached to the Offering Memorandum of the Trust
dated October [___], 1999; PROVIDED, FURTHER, that after the date that a
registration statement has been filed and so long as such Registration Statement
continues to be effective, only then may the Registrar permit transfers for

<PAGE>   97


                          [FORM OF REVERSE OF SECURITY]

         Distributions on each Common Security will be payable at a rate of
9.875% per annum (the "Coupon Rate") of the liquidation amount of $1000 per
Common Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee. Distributions in arrears for more than one
semi-annual period will bear interest thereon compounded semi-annually at the
Coupon Rate (to the extent permitted by applicable law). Pursuant to the
Registration Rights Agreement, in certain limited circumstances the Debenture
Issuer will be required to pay Liquidated Damages (as defined in the
Registration Rights Agreement) with respect to the Debentures. The term
"Distributions", as used herein, includes such cash distributions and any and
all such interest and Liquidated Damages, if any, payable unless otherwise
stated. A Distribution is payable only to the extent that payments are made in
respect of the Debentures held by the Property Trustee and to the extent the
Property Trustee has funds legally available therefor.

         Distributions on the Common Securities will be cumulative, will accrue
from the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from October 18, 1999 and will be payable
semi-annually in arrears, on April 15 and October 15 of each year, commencing
April 15, 2000, except as otherwise described below. Distributions will be
computed on the basis of a 360-day year of twelve 30-day months. As long as no
Event of Default has occurred and is continuing under the Indenture, the
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period at any time and from time to time on
the Debentures for a period not exceeding 10 consecutive calendar semi-annual
periods, including the first such semi-annual period during such extension
period (each an "Extension Period"), PROVIDED THAT no Extension Period shall end
on a date other than an Interest Payment Date for the Debentures or extend
beyond the Maturity Date of the Debentures. As a consequence of such deferral,
Distributions will also be deferred. Notwithstanding such deferral, semi-annual
Distributions will continue to accumulate with interest thereon (to the extent
permitted by applicable law, but not at a rate exceeding the rate of interest
then accruing on the Debentures) at the Coupon Rate compounded semi-annually
during any such Extension Period. Prior to the termination of any Extension
Period, the Debenture Issuer may further defer payments of interest by further
extending such Extension Period; PROVIDED THAT such Extension Period, together
with all such previous and further extensions within such Extension Period, may
not (i) exceed 10 consecutive semi-annual periods, including the first
semi-annual period during such Extension Period, (ii) end on a date other than
an Interest Payment Date for the Debentures or (iii) extend beyond the Maturity
Date of the Debentures. Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the record date
immediately preceding the end of the Extension Period. Upon the termination of
any Extension Period and the payment of all amounts then due, the Debenture
Issuer may commence a new Extension Period, subject to the above requirements.

         Subject to the receipt by the Sponsor of any and all required
regulatory approvals and to certain other conditions set forth in the
Declaration and the Indenture, the Property Trustee may, at the direction of the
Sponsor, at any time dissolve the Trust and cause the Debentures to be
distributed to the Holders of the Securities in liquidation of the Trust or,
simultaneously with any redemption of the Debentures, cause a Like Amount of the
Securities to be redeemed by the Trust.

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

         Under certain circumstances, the rights of the holders of the Common
Securities shall be subordinate to the rights of the holders of the Capital
Securities, as provided in the Declaration.
