            Within 60 days after May 15 of each year, the Institutional Trustee

SECTION 2.6 Defaults; Waiver.

            (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 Default in respect of the Capital Securities and its
consequences, provided, that if the underlying Default under the Indenture:

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

            (ii)  is waivable only with the consent of holders of more than a
      majority in principal amount of the Debentures (a "Super Majority")
      affected thereby, only 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 may waive such Default in respect of the Capital Securities
      under the Declaration.

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
Securities, as permitted by the Trust Indenture Act. Upon such waiver, any such
default shall cease to exist, and any Default with respect to the Capital
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 a Default with respect to the Capital Securities or impair
any right consequent thereon. Any waiver by the Holders of the Capital
Securities of a 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 Default with

                                       8
<PAGE>

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 Default with respect to the Common Securities and its
consequences, provided, that if the underlying 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 Default under the
      Declaration as provided in this Section 2.6(b), the Default under the
      Declaration shall also not be waivable; or

            (ii)  is waivable only with the consent of a Super Majority, except
      where the Holders of the Common Securities are deemed to have waived such
      Default under the Declaration as provided in this Section 2.6(b), only the
      Holders of at least the proportion in aggregate liquidation amount of the
      Common Securities that the relevant Super Majority represents of the
      aggregate principal amount of the Debentures outstanding may waive such
      Default in respect of the Common Securities under the Declaration;

provided, further each Holder of Common Securities will be deemed to have waived
any such Default and all Defaults with respect to the Common Securities and its
consequences until all Defaults with respect to the Capital Securities have been
cured, waived or otherwise eliminated, and until such Defaults with respect to
the Capital Securities have been so cured, waived or otherwise eliminated, the
Institutional 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 Institutional 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 the waiver of a Default by the Holders of a Majority in liquidation
amount of the Common Securities, any such default shall cease to exist and any
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 Default with respect to the
Common Securities or impair any right consequent thereon.

      (c)   A waiver of a Default under the Indenture by the Institutional
Trustee at the direction of the Holders of the Capital Securities, constitutes a
waiver of the corresponding 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
is hereby expressly excluded from this Declaration and the Securities, as
permitted by the Trust Indenture Act.

SECTION 2.7 Default; Notice.

                                       9
<PAGE>

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

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

            (i)   a default under Sections 5.7(b) and 5.7(c) of the Indenture;
      or

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

            (a)   The legal title to the Debentures shall be owned by and held

the Holders of the Securities. The right, title and interest of the

      of the Debentures held by the Institutional Trustee, deposit such funds
      into the Institutional Trustee Account and make payments to the Holders of
      the Capital Securities and Holders of the Common Securities from the
      Institutional Trustee Account in accordance with Section 6.1. Funds in the
      Institutional Trustee Account shall be held uninvested until disbursed in
      accordance with this Declaration. The Institutional Trustee Account shall
      be an account that is maintained with a banking institution the rating on
      whose long-term unsecured indebtedness assigned by a "nationally
      recognized statistical rating organization," as that term is defined for

      the rating assigned to the Capital Securities 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 Capital Securities and the

      Trustees in accordance with the terms of the Securities, engage in such

      occurrence of certain Special Events or other specified circumstances
      pursuant to the terms of the Securities.

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

            (e)   Subject to Section 2.6, the Institutional Trustee shall take
any Legal Action which arises out of or in connection with a Default of which a
Responsible Officer of the Institutional Trustee has actual knowledge or the
Institutional Trustee's duties and obligations under this Declaration or the
Trust Indenture Act.

            (f)   The Institutional Trustee shall not resign as a Trustee unless
either:

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

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

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

                                       15

of the Debentures subject to the rights of the Holders pursuant to the terms of
such Securities, this Declaration, the Statutory Trust Act and the Trust
Indenture Act.

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

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

            The Institutional Trustee must exercise the powers set forth in this

            (a)   The Institutional Trustee, before the occurrence of any
Default and after the curing of all Defaults that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Declaration and no implied covenants shall be read into this Declaration against
the Institutional Trustee. In case a Default has occurred (that has not been
cured or waived pursuant to Section 2.6) of which a Responsible Officer of the
Institutional Trustee has actual knowledge, the Institutional Trustee shall
exercise such of the rights and powers vested in it by this Declaration, and use
the same degree of care and skill in the exercise of such rights and powers, 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 Institutional Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

            (i)   prior to the occurrence of a Default and after the curing or
      waiving of all such Defaults that may have occurred:

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

                  (B)   in the absence of bad faith on the part of the
            Institutional Trustee, the Institutional 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 Institutional Trustee and conforming to the
            requirements

                                       16

            of this Declaration; but in the case of any such certificates or
            opinions that by any provision hereof are specifically required to
            be furnished to the Institutional Trustee, the Institutional Trustee
            shall be under a duty to examine the same to determine whether or
            not they conform to the requirements of this Declaration;

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

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

            (iv)  no provision of this Declaration shall require the
      Institutional 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, if it shall have reasonable
      grounds for believing that the repayment of such funds or liability is not
      reasonably assured to it under the terms of this Declaration or indemnity
      reasonably satisfactory to the Institutional Trustee against such risk or
      liability is not reasonably assured to it;

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

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

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

      including such reasonable advances as may be requested by the
      Institutional Trustee provided that nothing contained in this Section

      powers vested in it by this Declaration;

            (vii) the Institutional Trustee shall not be bound to make any

            (a)   The Trust may not consolidate, amalgamate, merge with or into,

            (b)   The Trust may, with the consent of the Regular Trustees or, if
there are more than two, a majority of the Regular Trustees and without the
consent of the Holders of the Securities, the Delaware Trustee or the
Institutional Trustee, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State; provided,
that:

            (i)   such successor entity (the "Successor Entity") either:

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

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

            (ii)  the Debenture Issuer expressly acknowledges a trustee of the
      Successor Entity that possesses the same powers and duties as the
      Institutional Trustee in its capacity as the Holder of the Debentures;

            (iii) the Capital Securities or any Successor Securities are listed,
      or any Successor Securities will be listed upon notification of issuance,
      on any national

                                       20
<PAGE>

      securities exchange or with any other organization on which the Capital
      Securities are then listed or quoted;

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

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

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

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

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

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

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

            (viii) the Sponsor guarantees the obligations of such Successor
      Entity under the Successor Securities at least to the extent provided by
      the Capital Securities Guarantee.

            (c)   Notwithstanding Section 3.15(b), the Trust shall not, except
with the consent of Holders of 100% in liquidation amount of the Securities,
consolidate, amalgamate, merge with or into, or be replaced by any other entity
or permit any other entity to consolidate, amalgamate, merge with or into, or
replace it, if in the opinion of a nationally recognized independent tax counsel
experienced in such matters, such consolidation, amalgamation, merger or
replacement would cause the Trust or the Successor Entity to be classified as
other than a grantor trust for United States federal income tax purposes.

                                   ARTICLE IV

            (d)   a Regular Trustee may, by power of attorney consistent with
applicable law, delegate to any other natural person over the age of 21 his or
her power for the purposes of signing any documents which the Regular Trustees
have power and authority to cause the Trust to execute pursuant to Section 3.6.

Trustee and delivered to the Regular Trustees and the Sponsor; and

            (ii)  the Trustee that acts as Delaware Trustee shall not be removed

delivery or upon such later date as is specified therein; provided, however,
that:

            (i)   No such resignation of the Trustee that acts as the
      Institutional Trustee shall be effective:

                        (A)   until a Successor Institutional Trustee has been
            appointed and has accepted such appointment by instrument executed
            by such Successor Institutional Trustee and delivered to the Trust,
            the Sponsor and the resigning Institutional Trustee; or

      resigning Delaware Trustee.

            (d)   The Holders of the Common Securities shall use their best
efforts to promptly appoint a Successor Delaware Trustee or Successor

Trustee shall have been appointed and accepted appointment as provided in this
Section 5.6 within 60 days after delivery to the Sponsor and the Trust of an
instrument of resignation, the resigning Institutional Trustee or Delaware
Trustee, as applicable, may petition any court of competent jurisdiction for
appointment of a Successor Institutional Trustee or Successor Delaware Trustee.
Such court may thereupon, after prescribing such notice, if any, as it may deem
proper and prescribe, appoint a Successor Institutional Trustee or Successor
Delaware Trustee, as the case may be.

            (f)   No Institutional Trustee or Delaware Trustee shall be liable
for the acts or omissions to act of any Successor Institutional Trustee or

SECTION 5.7 Vacancies among Trustees.

            If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees is
increased pursuant to Section 5.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by the Regular Trustees or, if there
are more than two, a majority of the Regular Trustees shall be conclusive

Trustee appointed in accordance with Section 5.6.

<PAGE>

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 annul the Trust. Whenever a vacancy in the number
of Regular Trustees shall occur, until such vacancy is filled by the appointment
of a Regular Trustee in accordance with Section 5.6, the Regular Trustees in
office, regardless of their number, shall have all the powers granted to the
Regular Trustees and shall discharge all the duties imposed upon the Regular
Trustees by this Declaration.

SECTION 5.9 Meetings.

            If there is more than one Regular Trustee, meetings of the Regular
Trustees shall be held from time to time upon the call of any Regular Trustee.
Regular meetings of the Regular Trustees may be held at a time and place fixed
by resolution of the Regular Trustees. Notice of any in-person meetings of the
Regular Trustees shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 48
hours before such meeting. Notice of any telephonic meetings of the Regular
Trustees or any committee thereof shall be hand delivered or otherwise delivered
in writing (including by facsimile, with a hard copy by overnight courier) not
less than 24 hours before a meeting. Notices shall contain a brief statement of
the time, place and anticipated purposes of the meeting. The presence (whether
in person or by telephone) of a Regular Trustee at a meeting shall constitute a
waiver of notice of such meeting except where a Regular 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 Regular Trustees may
be taken at a meeting by vote of a majority of the Regular 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 Regular Trustees. In the event there is only one Regular
Trustee, any and all action of such Regular Trustee shall be evidenced by a
written consent of such Regular Trustee.

SECTION 5.10 Delegation of Power.

            (a)   Any Regular Trustee may, by power of attorney consistent with
applicable law, delegate to any other natural person over the age of 21 his or
her power for the purpose of executing any documents contemplated in Section
3.6, including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

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

SECTION 5.11 Merger, Conversion, Consolidation or Succession to Business.

                                       27
<PAGE>

            Any corporation into which the Institutional Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either may
be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Institutional Trustee or the Delaware Trustee, as the
case may be, shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Institutional Trustee or
the Delaware Trustee, as the case may be, shall be the successor of the
Institutional Trustee or the Delaware Trustee, as the case may be, hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

                                   ARTICLE VI

SECTION 6.1 Distributions.

            Holders shall receive Distributions (as defined herein) in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Capital Securities and the Common Securities
in accordance with the preferences set forth in their respective terms. If and
to the extent that the Debenture Issuer makes a payment of interest (including
Compounded Interest (as defined in the Indenture) and Additional Interest (as
defined in the Indenture)), premium and/or principal on the Debentures held by
the Institutional Trustee (the amount of any such payment being a "Payment
Amount"), the Institutional Trustee shall and is directed to make a distribution
(a "Distribution") of the Payment Amount to Holders.

                                   ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1 General Provisions Regarding Securities.

            (a)   The Regular Trustees shall on behalf of the Trust issue one
class of capital securities representing undivided beneficial interests in the
assets of the Trust having such terms as are set forth in Annex I (the "Capital
Securities") and one class of common securities representing undivided
beneficial interests in the assets of the Trust having such terms as are set
forth in Annex I (the "Common Securities"). The Trust shall issue no securities
or other interests in the assets of the Trust other than the Capital Securities
and the Common Securities.

            (b)   The Certificates shall be signed on behalf of the Trust by a
Regular Trustee. Such signature shall be the manual or facsimile signature of
any present or any future Regular Trustee. In case any Regular Trustee of the
Trust who shall have signed any of the Securities shall cease to be such Regular
Trustee before the Certificates so signed shall be delivered by the Trust, such
Certificates nevertheless may be delivered as though the person who signed such
Certificates had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Regular Trustees of the Trust, although
at the date of the execution and delivery of the Declaration any such person was
not such a Regular Trustee. Certificates shall be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Regular Trustees, as evidenced by their execution thereof, and may have such

                                       28
<PAGE>

letters, numbers or other marks of identification or designation and such
legends or endorsements as the Regular Trustees may deem appropriate, or as may
be required to comply with any law or with any rule or regulation of any stock
exchange on which Securities may be listed, or to conform to usage.

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

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

            (e)   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.

            (iv)  Subject to obtaining any required regulatory approval, when
      all of the Securities have been called for redemption and the amounts
      necessary for redemption thereof have been paid to the Holders in
      accordance with the terms of the Securities;

            (v)   Subject to obtaining any required regulatory approval, when
      the Trust shall have been dissolved in accordance with the terms of the
      Securities upon election by the Sponsor of its right to terminate the
      Trust and distribute all of the Debentures to the Holders of Securities in
      exchange for all of the Securities and all of the Debentures shall have
      been distributed to the Holders of Securities in accordance with such
      election;

            (vi)  before the issuance of any Securities, with the consent of all
      of the Regular Trustees and the Sponsor; or

                                       29

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
the terms of the Securities. 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 shall be freely
transferable.

            (c)   Subject to this Article IX, the Sponsor and any Related Party
may only transfer Common Securities to the Sponsor or a Related Party of the
Sponsor; provided, that any such transfer is subject to the condition precedent
that the transferor obtain the written opinion of nationally recognized
independent counsel experienced in such matters that such transfer would not
cause more than an insubstantial risk that:

            (i)   the Trust would not be classified for United States federal
      income tax purposes as a grantor trust; and

            (ii)  the Trust would be an Investment Company or the transferee
      would become an Investment Company.

SECTION 9.2 Transfer of Certificates.

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

SECTION 9.3 Deemed Security Holders.

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

SECTION 9.4 Book Entry Interests.

            Unless otherwise specified in the terms of the Capital Securities,
the Capital Securities Certificates, on original issuance, will be issued in the
form of one or more, fully registered, global Capital Security Certificates
(each a "Global Certificate"), to be delivered to DTC, the initial Clearing
Agency, by, or on behalf of, the Trust. Such Global Certificates shall initially
be registered on the books and records of the Trust in the name of Cede & Co.,
the nominee of DTC, and no Capital Security Beneficial Owner will receive a
definitive Capital Security Certificate representing such Capital Security
Beneficial Owner's interests in such Global Certificates, except as provided in
Section 9.7. Unless and until definitive, fully registered Capital Security
Certificates (the "Definitive Capital Security Certificates") have been issued
to the Capital Security Beneficial Owners pursuant to Section 9.7:

            (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 Certificates and receiving approvals, votes or
consents hereunder) as the Holder of the Capital Securities and the sole holder
of the Global Certificates 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 between such Capital Security Beneficial
Owners and the Clearing Agency and/or the Clearing Agency Participants and
receive and transmit payments of Distributions on the Global Certificates to
such Clearing Agency Participants. DTC will 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 under this Declaration, unless and until Definitive Capital
Security Certificates shall have been issued to the Capital Security Beneficial
Owners pursuant to Section 9.7, the Regular Trustees shall give all such notices
and communications specified herein to be given to the Capital Security Holders
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 a
securities depositary with respect to the Capital Securities, the Regular
Trustees may, in their sole discretion, appoint a successor Clearing Agency with
respect to such Capital Securities.

SECTION 9.7 Definitive Capital Security Certificates.

            If:

            (a)   a Clearing Agency elects to discontinue its services as a
securities depositary with respect to the Capital Securities and a successor
Clearing Agency is not appointed within 90 days after such discontinuance
pursuant to Section 9.6; or

            (b)   the Regular Trustees elect after consultation with the Sponsor
to terminate the book entry system through the Clearing Agency with respect to
the Capital Securities,

then:

            (c)   Definitive Capital Security Certificates shall be prepared by
the Regular Trustees on behalf of the Trust with respect to such Capital
Securities; and

            (d)   upon surrender of the Global Certificates by the Clearing
Agency, accompanied by registration instructions, the Regular Trustees shall
cause Definitive Certificates to be delivered to Capital Security Beneficial
Owners in accordance with the instructions of the Clearing Agency. Neither the
Trustees nor the Trust shall be liable for any delay in delivery of such
instructions and each of them may conclusively rely on and shall be protected in
relying on, said instructions of the Clearing Agency. The Definitive Capital
Security Certificates shall be printed, lithographed or engraved or may be
produced in any other manner as is reasonably acceptable to the Regular
Trustees, as evidenced by their execution thereof, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements as the Regular Trustees may deem appropriate, or as may be required
to comply with any law or with any rule or regulation made pursuant thereto or
with any rule or regulation of any stock exchange on which Capital Securities
may be listed, or to conform to usage.

SECTION 9.8 Mutilated, Destroyed, Lost or Stolen Certificates.

            If:

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

            (b)   there shall be delivered to the Regular Trustees such security
or indemnity as may be required by them to keep each of them harmless.

then, in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any Regular Trustee on behalf of the Trust shall execute
and deliver, in exchange for

                                       32
<PAGE>

or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like denomination. In connection with the issuance of any new
Certificate under this Section 9.8, the Regular Trustees may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection therewith. Any duplicate Certificate issued pursuant to
this Section shall constitute conclusive evidence of an ownership interest in
the relevant Securities, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

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

            (i)   personally liable for the return of any portion of the capital

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
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,

<PAGE>

reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders of Securities might properly be paid.

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

      Covered Persons; 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 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.

                                       34
<PAGE>

            (a)   (i)   The Debenture Issuer 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), 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 Debenture Issuer 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) 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.

            (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 Debenture
      Issuer 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 Regular Trustees by a majority vote of a quorum consisting of such
      Regular 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 Regular Trustees so directs, by

                                       35
<PAGE>

      independent legal counsel in a written opinion, or (3) by the Common
      Security Holder of the Trust.

            (v)   Expenses (including attorneys' fees) 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 Debenture Issuer in
      advance of the final disposition of such action, suit or proceeding upon
      receipt of an undertaking by or on behalf of such Company Indemnified
      Person to repay such amount if it shall ultimately be determined that he
      is not entitled to be indemnified by the Debenture Issuer as authorized in
      this Section 10.4(a). Notwithstanding the foregoing, no advance shall be
      made by the Debenture Issuer if a determination is reasonably and promptly
      made (i) by the Regular Trustees by a majority vote of a quorum of
      disinterested Regular Trustees, (ii) if such a quorum is not obtainable,
      or, even if obtainable, if a quorum of disinterested Regular Trustees so
      directs, by independent legal counsel in a written opinion or (iii) the
      Common Security Holder of the Trust, that, based upon the facts known to
      the Regular 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 such person did not believe to be in or not
      opposed to the best interests of the Trust, or, with respect to any
      criminal proceeding, that such 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 Regular Trustees, independent
      legal counsel or Common Security Holder reasonably determine that such
      person deliberately breached his duty to the Trust or its Common or
      Capital Security Holders.

            (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
      Debenture Issuer or Capital Security Holders of the Trust or otherwise,
      both as to action in his official capacity and as to action in another
      capacity while holding such office. All rights to indemnification under
      this Section 10.4(a) shall be deemed to be provided by a contract between
      the Debenture Issuer and each Company Indemnified Person who serves in
      such capacity at any time while this Section 10.4(a) is in effect. Any
      repeal or modification of this Section 10.4(a) shall not affect any rights
      or obligations then existing.

            (vii) The Debenture Issuer 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

                                       36
<PAGE>

      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 Debenture Issuer agrees to indemnify the (i) Institutional
Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Institutional
Trustee and the Delaware Trustee, and (iv) any officers, directors,
shareholders, members, partners, employees, representatives, custodians,
nominees or agents of the Institutional Trustee and the Delaware Trustee (each
of the Persons in (i) through (iv) being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any loss, liability or expense incurred without negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration or
the trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against or investigating
any claim or liability in connection with the exercise or performance of any of
its powers or duties hereunder. The obligation to indemnify as set forth in this
Section 10.4(b) shall survive the resignation or removal of the Institutional
Trustee or the Delaware Trustee, as the case may be, and the satisfaction and
discharge of this Declaration.

SECTION 10.5 Outside Businesses.

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

SECTION 11.1 Fiscal Year.

                                       37
<PAGE>

            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 Regular
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 Regular Trustees.

            (b)   The Regular Trustees shall cause to be prepared and delivered
to each of the Holders of Securities, to the extent, if any, required by the
Trust Indenture Act, within 90 days after the end of each Fiscal Year of the
Trust, annual financial statements of the Trust, including a balance sheet of
the Trust as of the end of such Fiscal Year, and the related statements of
income or loss;

            (c)   The Regular Trustees shall cause to be duly prepared and
delivered to each of the Holders of Securities, 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 deliver any such statement at a later date, the Regular Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

            (d)   The Regular 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 Regular Trustees on behalf of the Trust with any state or local taxing
authority.

SECTION 11.3 Banking.

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

SECTION 11.4 Withholding.

            The Trust and the Regular 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

                                       38
<PAGE>

shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations. The Regular Trustees
shall file required forms with applicable jurisdictions and, unless an exemption
from withholding is properly established by a Holder, shall remit amounts
withheld with respect to the Holder to applicable jurisdictions. To the extent
that the Trust is required to withhold and pay over any amounts to any authority
with respect to distributions or allocations to any Holder, the amount withheld
shall be deemed to be a distribution in the amount of the withholding to the
Holder. In the event of any claimed overwithholding, Holders shall be limited to
an action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

SECTION 12.2 Meetings of the Holders of Securities; Action by Written Consent.

                                       40
<PAGE>

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

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

            (i)   notice of any such meeting shall be given to all the Holders
      of Securities having a right to vote thereat at least 7 days and not more
      than 60 days before the date of such meeting. Whenever a vote, consent or
      approval of the Holders of Securities is permitted or required under this
      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 of Securities. Any
      action that may be taken at a meeting of the Holders of Securities may be
      taken without a meeting if a consent in writing setting forth the action
      so taken is signed by the Holders of Securities owning not less than the
      minimum amount of Securities in liquidation amount that would be necessary
      to authorize or take such action at a meeting at which all Holders of
      Securities having a right to vote thereon were present and voting. Prompt
      notice of the taking of action without a meeting shall be given to the
      Holders of Securities entitled to vote who have not consented in writing.
      The Regular 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 Regular
      Trustees;

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

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

                                       41
<PAGE>

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

                              AND DELAWARE TRUSTEE

SECTION 13.1 Representations and Warranties of Institutional Trustee.

            The Trustee that acts as initial Institutional Trustee represents
and warrants to the Trust and to the Sponsor at the date of this Declaration,
and each Successor Institutional Trustee represents and warrants to the Trust
and the Sponsor at the time of the Successor Institutional Trustee's acceptance
of its appointment as Institutional Trustee that:

            (a)   the Institutional Trustee is a banking corporation with trust
powers, duly organized, validly existing and in good standing under the laws of
the State of New York, with trust power and authority to execute and deliver,
and to carry out and perform its obligations under the terms of, this
Declaration;

            (b)   the execution, delivery and performance by the Institutional
Trustee of the Declaration has been duly authorized by all necessary corporate
action on the part of the Institutional Trustee. The Declaration has been duly
executed and delivered by the Institutional Trustee, and it constitutes a legal,
valid and binding obligation of the Institutional Trustee, enforceable against
it in accordance with its terms, subject to applicable bankruptcy,
reorganization, moratorium, insolvency, and other similar laws affecting
creditors' rights generally and to general principles of equity and the
discretion of the court (regardless of whether the enforcement of such remedies
is considered in a proceeding in equity or at law);

or notice to, any State or Federal banking authority is required for the
execution, delivery or performance by the Institutional Trustee, of the
Declaration.

                                     ANNEX I

                                    TERMS OF
                              % CAPITAL SECURITIES
                               % COMMON SECURITIES

            Pursuant to Section 7.1 of the Amended and Restated Declaration of
Trust, dated as of , 20 (as amended from time to time, the "Declaration"), the
designation, rights, privileges, restrictions, preferences and other terms and
provisions of the Capital Securities and the Common 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
Prospectus referred to below):

            1.    Designation and Number.

            (a)   Capital Securities. Capital Securities of the Trust (or up to
Capital Securities if the over-allotment option is exercised pursuant to Section
of the Underwriting Agreement) with an aggregate liquidation amount with respect
to the assets of the Trust of    dollars ($ ) (or up to     ($ ) if the
over-allotment option is exercised pursuant to Section of the Underwriting
Agreement), and a liquidation amount with respect to the assets of the Trust of
$ per capital security, are hereby designated for the purposes of identification
only as "  % Capital Securities" (the "Capital Securities"). The Capital
Security 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 stock exchange on which the Capital
Securities are listed.

            (b)   Common Securities. Common Securities of the Trust (or up to
Common Securities if the over-allotment option is exercised pursuant to Section
of the Underwriting Agreement) with an aggregate liquidation amount with respect
to the assets of the Trust of     dollars ($ ) (or up to     ($ ) if the
over-allotment option is exercised pursuant to Section of the Underwriting
Agreement), and a liquidation amount with respect to the assets of the Trust of
$ per common security, are hereby designated for the purposes of identification
only as "   % Common Securities" (the "Common Securities"). The Common Security
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 payable on each Security will be fixed at a rate
per annum of % (the "Coupon Rate") of the stated liquidation amount of $ per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Institutional Trustee. Distributions in arrears beyond the first
date such Distributions are payable (or would be payable, if not for any
Extension Period (as defined below) or default by the Debenture Issuer on the
Debentures) will bear interest thereon compounded quarterly at the Coupon Rate
(to the extent permitted by

                                       I-1

<PAGE>

applicable law). The term "Distributions" as used herein includes such cash
distributions and any such interest payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Institutional Trustee and to the extent the
Institutional Trustee has funds available therefor. The amount of Distributions
payable for any period will be computed for any full quarterly Distribution
period on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed per 90-day quarter.

            (b)   Distributions on the Securities will be cumulative, will
accrue from and including , 20 , and will be payable quarterly in arrears, on ,
,   and of each year, commencing on , 20 . When, as and if available for
payment, Distributions will be made by the Institutional Trustee, except as
otherwise described below. The Debenture Issuer has the right under the
Indenture to defer payments of interest on the Debentures by extending the
interest payment period from time to time on the Debentures for a period not
exceeding 20 consecutive quarters (each an "Extension Period"), during which
Extension Period no interest shall be due and payable on the Debentures,
provided, that no Extension Period may extend beyond the date of maturity of the
Debentures. As a consequence of the Debenture Issuer's extension of the interest
payment period, quarterly Distributions will also be deferred. Despite such
deferral, quarterly Distributions will continue to accrue with interest thereon
(to the extent permitted by applicable law) at the Coupon Rate compounded
quarterly during any such Extension Period. In the event that the Debenture
Issuer exercises its right to extend the interest payment period, then (a) the
Debenture Issuer shall not declare or pay any dividend on, make any
distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock or make any
guarantee payment with respect thereto (other than (i) repurchases, redemptions
or other acquisitions of shares of capital stock of Citigroup in connection with
any employment contract, benefit plan or other similar arrangement with or for
the benefit of employees, officers, directors or consultants, (ii) as a result
of an exchange or conversion of any class or series of Citigroup's capital stock
for any other class or series of Citigroup's capital stock, or (iii) the
purchase of fractional interests in shares of Citigroup's capital stock pursuant
to the conversion or exchange provisions of such capital stock or the security
being converted or exchanged) and (b) the Debenture Issuer shall not make any
payment of interest on or principal of (or premium, if any, on), or repay,
repurchase or redeem, any debt securities issued by the Debenture Issuer that
rank pari passu with or junior to the Debentures. The foregoing, however, will
not apply to any stock dividends paid by Citigroup where the dividend stock is
the same stock as that on which the dividend is being paid. Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided, that such Extension Period, together
with all such previous and further extensions thereof, may not exceed 20
consecutive quarters; provided further, that no Extension Period may extend
beyond the maturity of the Debentures. Payments of deferred Distributions and
accrued interest thereon will be payable to Holders as they appear on the books
and records of the Trust on the first record date after 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. The Regular Trustees will give notice to each
Holder of any Extension Period upon their receipt of notice thereof from the
Debenture Issuer.

                                       I-2

<PAGE>

            (c)   Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust at the close of
business on the relevant record dates. While the Capital Securities remain in
book-entry only form, the relevant record dates shall be one Business Day prior
to the relevant payment dates which payment dates shall correspond to the
interest payment dates on the Debentures. Subject to any applicable laws and
regulations and the provisions of the Declaration, each such payment in respect
of the Capital Securities will be made as described under the heading
"Description of the Capital Securities -- Book-Entry Only Issuance" in the
Prospectus dated , 20 (the "Prospectus"), of the Trust included in the
Registration Statement on Form S-3 of the Sponsor, the Trust and certain other
statutory trusts. The relevant record dates for the Common Securities shall be
the same record date as for the Capital Securities. If the Capital Securities
shall not continue to remain in book-entry only form, the relevant record dates
for the Capital Securities shall conform to the rules of any securities exchange
on which the securities are listed and, if none, shall be selected by the
Regular Trustees, which dates shall be more than 14 days but less than 60 days
prior to the relevant payment dates, which payment dates shall correspond to the
interest payment dates on the Debentures. Distributions payable on any
Securities that are not punctually paid on any Distribution payment date, as a
result of the Debenture Issuer having failed to make a payment under the
Debentures, will cease to be payable to the Person in whose name such Securities
are registered on the relevant record date, and such defaulted Distribution will
instead be payable to the Person in whose name such Securities are registered on
the special record date or other specified date determined in accordance with
the Indenture. If any date on which Distributions are payable on the Securities
is not a Business Day, then payment of the Distribution payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case 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 of the Securities.

            3.    Liquidation Distribution Upon Dissolution.

            (a)   In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust, the Holders of the Securities on the
date of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive out of the assets of the Trust available for distribution to
Holders of Securities after satisfaction of liabilities of creditors,
distributions in an amount equal to the aggregate of the stated liquidation
amount of $       per Security plus accrued and unpaid Distributions thereon to
the date of payment (such amount being the "Liquidation Distribution"), unless,
in connection with such dissolution, winding-up or termination, Debentures in an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate equal to the Coupon Rate, and bearing accrued and unpaid
interest in an amount equal to the accrued and unpaid Distributions on, such
Securities outstanding at such time, have been distributed on a Pro Rata basis
to the Holders of the Securities in exchange for such Securities. Prior to any
such Liquidation Distribution, the Debenture Issuer will obtain any required
regulatory approval.

                                       I-3

<PAGE>

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

            4.    Redemption and Distribution.

            (a)   Upon the repayment of the Debentures in whole or in part,
whether at maturity or upon redemption (either at the option of the Debenture
Issuer or pursuant to a Special Event as described below), the proceeds from
such repayment or payment shall be simultaneously applied to redeem Securities
having an aggregate liquidation amount equal to the aggregate principal amount
of the Debentures so repaid or redeemed at a redemption price of $ per Security
plus an amount equal to accrued and unpaid Distributions thereon at the date of
the redemption, payable in cash (the "Redemption Price"). Holders shall be given
not less than 30 nor more than 60 days' notice of such redemption. Prior to any
such redemption, the Debenture Issuer will obtain any required regulatory
approval.

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

            (c)   Subject to obtaining any required regulatory approval, if, at
any time, a Tax Event, an Investment Company Event or a Regulatory Capital Event
(each as defined below, and each a "Special Event") shall occur and be
continuing, Citigroup shall have the right, upon not less than 30 nor more than
60 days' notice, to redeem the Debentures, in whole or in part, for cash within
90 days following the occurrence of such Special Event, and, following such
redemption, Securities with an aggregate liquidation amount equal to the
aggregate principal amount of the Debentures so redeemed shall be redeemed by
the Trust at the Redemption Price on a Pro Rata basis; provided, however, that
if at the time there is available to Citigroup or the Trust the opportunity to
eliminate, within such 90-day period, the Special Event by taking some
ministerial action, such as filing a form or making an election or pursuing some
other similar reasonable measure that will have no adverse effect on the Trust,
Citigroup or the holders of the Securities, then Citigroup or the Trust will
pursue such measure in lieu of redemption.

            "Tax Event" means that the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "Tax Event Opinion") 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 amendment to, or
change in, an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority (including
the enactment of any legislation and the publication of any judicial decision or
regulatory determination on or after the date of the Prospectus), in either case
after the date of the Prospectus, there is more than an insubstantial risk that
(i) the Trust would be subject to United States federal income tax with respect
to interest accrued or received on the Debentures, (ii) the Trust would be
subject to more than a de minimis amount of other taxes, duties or other
governmental charges, or (iii) interest payable to the Trust

                                       I-4

<PAGE>

on the Debentures would not be deductible, in whole or in part, by the Debenture
Issuer for United States federal income tax purposes.

            "Investment Company Event" means that the Regular Trustees shall
have received an opinion of a nationally recognized independent counsel
experienced in practice under the Investment Company Act (an "Investment Company
Event Opinion") to the effect that, as a result of the occurrence of a change in
law or regulation or a written change in interpretation or application of law or
regulation by any legislative body, court, governmental agency or regulatory
authority (a "Change in 1940 Act Law"), there is a more than an insubstantial
risk that the Trust is or will be considered an Investment Company which is
required to be registered under the Investment Company Act, which Change in 1940
Act Law becomes effective on or after the date of the Prospectus.

            "Regulatory Capital Event" means a determination by Citigroup, based
on an opinion of counsel experienced in such matters (who may be an employee of
Citigroup or any of its affiliates), that, as a result of (a) any amendment to,
clarification of or change (including any announced prospective change) in
applicable laws or regulations or official interpretations thereof or policies
with respect thereto or (b) any official administrative pronouncement or
judicial decision interpreting or applying such laws or regulations, which
amendment, clarification, change, pronouncement or decision is announced or is
effective after the date of the Prospectus, there is more than an insubstantial
risk that the Capital Securities will no longer constitute Tier I Capital of
Citigroup or any bank holding company of which Citigroup is a subsidiary (or its
equivalent) for purposes of the capital adequacy guidelines or policies of the
Board of Governors of the Federal Reserve System or its successor as Citigroup's
primary federal banking regulator.

            On and from the date fixed by the Regular Trustees for any
distribution of the Debentures and dissolution of the Trust: (i) the Securities
will no longer be deemed to be outstanding, (ii) DTC or its nominee (or any
successor Clearing Agency or its nominee), as the record 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, except for certificates representing
Capital Securities held by DTC or its nominee (or any successor Clearing Agency
or its nominee), will be deemed to represent beneficial interests in the
Debentures having an aggregate principal amount equal to the aggregate stated
liquidation amount of, with an interest rate identical to the Coupon Rate of,
and accrued and unpaid interest equal to accrued and unpaid Distributions on
such Securities until such certificates are presented to the Debenture Issuer or
its agent for transfer or reissue.

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

            (e)   If the Debentures are distributed to the Holders of the
Securities, pursuant to the terms of the Indenture, the Debenture Issuer will
use its best efforts to cause the Debentures to be listed on the New York Stock
Exchange or on such other exchange as the Capital Securities were listed
immediately prior to the distribution of the Debentures.

                                       I-5

<PAGE>

            (f)   Redemption or Distribution procedures will 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 of the
      Securities to be redeemed or exchanged not fewer than 30 nor more than 60
      days before the date fixed for redemption or exchange thereof which, in
      the case of a redemption, will be the date fixed for redemption of the
      Debentures. For purposes of the calculation of the date of redemption or
      exchange and the dates on which notices are given pursuant to this Section
      4(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 the Holders of the Securities. Each Redemption/Distribution Notice
      shall be addressed to the Holders of the Securities 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 Securities to be redeemed shall be redeemed Pro
      Rata from each Holder of Capital Securities, it being understood that, in
      respect of Capital Securities registered in the name of and held of record
      by DTC or its nominee (or any successor Clearing Agency or its nominee),
      the distribution of the proceeds of such redemption will be made to each
      Clearing Agency Participant (or Person on whose behalf such nominee holds
      such securities) 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 may only be issued if the
      Debentures are redeemed as set out in this Section 4 (which notice will be
      irrevocable), then (A) while the Capital Securities are in book-entry only
      form, with respect to the Capital Securities, by 12:00 noon, New York City
      time, on the redemption date, provided, that the Debenture Issuer has paid
      to the Institutional Trustee a sufficient amount of cash in connection
      with the related redemption or maturity of the Debentures, the
      Institutional Trustee will deposit irrevocably with DTC or its nominee (or
      successor Clearing Agency or its nominee) funds sufficient to pay the
      applicable Redemption Price with respect to the Capital Securities and
      will give DTC (or any successor Clearing Agency) irrevocable instructions
      and authority to pay the Redemption Price to the Holders of the Capital
      Securities, and (B) with respect to Capital Securities issued in
      definitive form and Common Securities, provided, that the Debenture Issuer
      has paid the Institutional Trustee a sufficient amount of cash in
      connection with the related redemption or maturity of the Debentures, the
      Institutional Trustee will pay the relevant Redemption Price to the
      Holders of such Securities by check mailed to the address of the relevant
      Holder appearing on the books and records of the Trust on the redemption
      date. If a Redemption/Distribution Notice shall have been given and funds
      deposited as required, 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 accrue on the Securities so called
      for redemption and all rights of the Holders of such Securities so called
      for redemption will cease, except the right of the Holders of such
      Securities to receive the

                                       I-6

<PAGE>

      Redemption Price, but without interest on such Redemption Price. Neither
      the Regular Trustees nor the Trust shall be required to register or cause
      to be registered the transfer of any Securities that have been so called
      for redemption. 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) except
      that, if such Business Day falls in the next calendar year, such payment
      will be made on the immediately preceding Business Day, in each case with
      the same force and effect as if made on such date fixed for redemption. If
      payment of the Redemption Price in respect of any Securities is improperly
      withheld or refused and not paid either by the Institutional Trustee or by
      the Sponsor as guarantor pursuant to the relevant Securities Guarantee,
      Distributions on such Securities will continue to accrue 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.

            (iv)  Redemption/Distribution Notices shall be sent by the Regular
      Trustees on behalf of the Trust to (A) in respect of the Capital
      Securities, DTC or its nominee (or any successor Clearing Agency or its
      nominee) if the Global Certificates have been issued or, if Definitive
      Capital Security Certificates have been issued, to the Holder thereof and
      (B) in respect of the Common Securities to the Holder thereof.

            (v)   Subject to the foregoing and applicable law (including,
      without limitation, United States federal securities laws), the Debenture
      Issuer or its affiliates 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) and 7 and as otherwise
required by law and the Declaration, the Holders of the Capital Securities will
have no voting rights.

            (b)   Subject to the requirements set forth in this paragraph, the
Holders of a Majority in aggregate liquidation amount of the Capital Securities,
voting separately as a class, may direct the time, method, and place of
conducting any proceeding for any remedy available to the Institutional Trustee,
or direct the exercise of any trust or power conferred upon the Institutional
Trustee under the Declaration, including the right to direct the Institutional
Trustee, as holder of the Debentures, to (i) direct the time, method and place
of conducting any proceeding for any remedy available to the Debenture Trustee,
or exercise any trust or power conferred on the Debenture Trustee with respect
to the Debentures, (ii) waive any past Default (as defined in the Indenture)
that is waivable under Section 5.6 of the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Debentures shall be
due and payable or (iv) consent to any amendment, modification or termination of
the Indenture or the Debentures where such consent shall be required; provided,
however, that, where a consent or action under the Indenture would require the
consent or act of each holder of each Debenture affected thereby, such consent
or action under the Indenture shall not be effective until each Holder of
Capital Securities shall have consented to such action or provided such consent.
The Institutional Trustee shall not revoke any action previously authorized or
approved by a vote of

                                       I-7

<PAGE>

the Holders of the Capital Securities. Except with respect to directing the
time, method and place of conducting a proceeding for a remedy available to the
Institutional Trustee, the Institutional Trustee, as holder of the Debentures,
shall not take any of the actions described in clauses (i), (ii), (iii) or (iv)
above unless the Institutional Trustee has obtained an opinion of a nationally
recognized independent tax counsel experienced in such matters to the effect
that as a result of such action, the Trust will not fail to be classified as a
grantor trust for United States federal income tax purposes. If the
Institutional Trustee fails to enforce its rights under the Debentures, any
Holder of Capital Securities may directly institute a legal proceeding against
the Debenture Issuer to enforce the Institutional Trustee's rights under the
Debentures without first instituting a legal proceeding against the
Institutional Trustee or any other Person or entity. If a Default under the
Declaration has occurred and is continuing and such event is attributable to the
failure of the Debenture Issuer to pay interest or principal on the Debentures
on the date such interest or principal is otherwise payable (or in the case of
redemption, on the redemption date), then a holder of Capital Securities may
also directly institute a proceeding for enforcement of payment to such holder
(a "Direct Action") of the principal of or interest on the Debentures having a
principal amount equal to the aggregate liquidation amount of the Capital
Securities of such holder on or after the respective due date specified in the
Debentures without first (i) directing the Institutional Trustee to enforce the
terms of the Debentures or (ii) instituting a legal proceeding directly against
the Debenture Issuer to enforce the Institutional Trustee's rights under the
Debentures. Except as provided in the preceding sentence, the Holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures. In connection with such Direct Action, Citigroup
will be subrogated to the rights of such Holder of Capital Securities under the
Declaration to the extent of any payment made by Citigroup to such holder of
Capital Securities in such Direct Action.

            Any required approval or direction of Holders of Capital Securities
may be given at a separate meeting of Holders of Capital Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Capital Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of 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 consents.

            No vote or consent of the Holders of the Capital Securities will be
required for the Trust to redeem and cancel Capital Securities or to distribute
the Debentures in accordance with this 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), (c) and 7 as otherwise
required by law and the Declaration, the Holders of the Common Securities will
have no voting rights.

            (b)   The Holders of the Common Securities are entitled, in
accordance with and subject to Article V of the Declaration, to vote to appoint,
remove or replace any Trustee or to increase or decrease the number of Trustees.

            (c)   Subject to Section 2.6 of the Declaration and only after the
Default with respect to the Capital Securities has been cured, waived, or
otherwise eliminated and subject to the requirements of the second to last
sentence of this paragraph, the Holders of a Majority in liquidation amount of
the Common Securities, voting separately as a class, may direct the time,
method, and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or direct the exercise of any trust or power conferred
upon the Institutional Trustee under the Declaration, including (i) directing
the time, method, place of conducting any proceeding for any remedy available to
the Debenture Trustee, or exercising any trust or power conferred on the
Debenture Trustee with respect to the Debentures, (ii) waiving any past Default
(as defined in the Indenture) that is waivable under Section 5.6 of the
Indenture, or (iii) exercising any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable, provided that,
where a consent or action under the Indenture would require the consent or act
of the Holders of greater than a majority in principal amount of Debentures
affected thereby (a "Super Majority"), the Institutional Trustee may only give
such consent or take such action at the written direction of the Holders of at
least the proportion in liquidation amount of the Common Securities which the
relevant Super Majority represents of the aggregate principal amount of the
Debentures outstanding. Pursuant to this Section 6(c), the Institutional Trustee
shall not revoke any action previously authorized or approved by a vote of the
Holders of the Capital Securities. Other than with respect to directing the
time, method and place of conducting any proceeding for any remedy available to
the Institutional Trustee or the Debenture Trustee as set forth above, the
Institutional Trustee shall not take any action in accordance with the
directions of the Holders of the Common Securities under this paragraph unless
the Institutional Trustee has obtained an opinion of tax counsel to the effect
that for the purposes of United States federal income tax the Trust will not be
classified as other than a grantor trust on account of such action. If the
Institutional Trustee fails to enforce its rights under the Declaration, any
Holder of Common Securities may institute a legal proceeding directly against
any Person to enforce the Institutional Trustee's rights under the Declaration,
without first instituting a legal proceeding against the Institutional Trustee
or any other Person.

            Any approval or direction of Holders of 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 Regular 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

                                       I-9

<PAGE>

Holders are entitled to vote or of such matter upon which written consent is
sought and (iii) instructions for the delivery of proxies or consents.

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

            7.    Amendments to Declaration and Indenture.

            (a)   In addition to any requirements under Section 12.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities as a
class, will be entitled to vote on such amendment or proposal (but not on any
other amendment or proposal) and such amendment or proposal shall not be
effective except with the approval of the Holders of at least a Majority in
liquidation amount of the Securities, voting together as a single class;
provided, however, if any amendment or proposal referred to in clause (i) above
would adversely affect only the Capital Securities or only the Common
Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a Majority in liquidation amount of such class of
Securities.

            (b)   In the event the consent of the Institutional Trustee as the
holder of the Debentures is required under the Indenture with respect to any
amendment, modification or termination on the Indenture or the Debentures, the
Institutional Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination and shall
vote with respect to such amendment, modification or termination as directed by
a Majority in liquidation amount of the Securities voting together as a single
class; provided, however, that where a consent under the Indenture would require
the consent of the holders of greater than a majority in aggregate principal
amount of the Debentures (a "Super Majority"), the Institutional Trustee may
only give such consent at the direction of the Holders of at least the
proportion in liquidation amount of the Securities which the relevant Super
Majority represents of the aggregate principal amount of the Debentures
outstanding; provided, further, that the Institutional Trustee shall not take
any action in accordance with the directions of the Holders of the Securities
under this Section 7(b) unless the Institutional Trustee has obtained an opinion
of tax counsel to the effect that for the purposes of United States federal
income tax the Trust will not be classified as other than a grantor trust on
account of such action.

            8.    Pro Rata.

            A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate liquidation amount of the Securities
held by the relevant Holder in relation to the aggregate liquidation amount of
all Securities outstanding unless, in relation to a payment, an a 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

                                      I-10

<PAGE>

according to the aggregate liquidation amount of Capital Securities held by the
relevant Holder relative to the aggregate liquidation amount of all Capital
Securities outstanding, and only after satisfaction of all amounts owed to the
Holders of the Capital Securities, to each Holder of Common Securities pro rata
according to the aggregate liquidation amount of Common Securities held by the
relevant Holder relative to the aggregate liquidation amount of all Common
Securities outstanding.

            9.    Ranking.

            The Capital Securities rank pari passu and payment thereon shall be
made Pro Rata with the Common Securities except that, where a Default (as
defined in the Indenture) occurs and is continuing under the Indenture in
respect of the Debentures held by the Institutional Trustee, the rights of
Holders of the Common Securities to payment in respect of Distributions and
payments upon liquidation, redemption and otherwise are subordinated to the
rights to payment of the Holders of the Capital Securities.

            10.   Listing.

            The Regular Trustees shall use their best efforts to cause the
Capital Securities to be listed on the New York Stock Exchange.

            11.   Acceptance of Securities Guarantee and Indenture.

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

            12.   No Preemptive Rights.

            The Holders of the Securities shall have no preemptive rights to
subscribe for any additional securities.

            13.   Miscellaneous.

            These terms constitute a part of the Declaration.

            The Sponsor will provide a copy of the Declaration or the Capital
Securities Guarantee, and the Indenture to a Holder without charge on written
request to the Sponsor at its principal place of business.

SECTION 2.6 Defaults; Waiver.

            (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 Default in respect of the Capital Securities and its
consequences, provided, that if the underlying Default under the Indenture:

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

            (ii) is waivable only with the consent of holders of more than a
      majority in principal amount of the Debentures (a "Super Majority")
      affected thereby, only 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 may waive such Default in respect of the Capital Securities
      under the Declaration.

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
Securities, as permitted by the Trust Indenture Act. Upon such waiver, any such
default shall cease to exist, and any Default with respect to the Capital
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 a Default with respect to the Capital Securities or impair
any right consequent thereon. Any waiver by the Holders of the Capital
Securities of a 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 Default with

                                       8
<PAGE>

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 Default with respect to the Common Securities and its
consequences, provided, that if the underlying 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 Default under the
      Declaration as provided in this Section 2.6(b), the Default under the
      Declaration shall also not be waivable; or

            (ii) is waivable only with the consent of a Super Majority, except
      where the Holders of the Common Securities are deemed to have waived such
      Default under the Declaration as provided in this Section 2.6(b), only the
      Holders of at least the proportion in aggregate liquidation amount of the
      Common Securities that the relevant Super Majority represents of the
      aggregate principal amount of the Debentures outstanding may waive such
      Default in respect of the Common Securities under the Declaration;

provided, further each Holder of Common Securities will be deemed to have waived
any such Default and all Defaults with respect to the Common Securities and its
consequences until all Defaults with respect to the Capital Securities have been
cured, waived or otherwise eliminated, and until such Defaults with respect to
the Capital Securities have been so cured, waived or otherwise eliminated, the
Institutional 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 Institutional 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 the waiver of a Default by the Holders of a Majority in liquidation
amount of the Common Securities, any such default shall cease to exist and any
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 Default with respect to the
Common Securities or impair any right consequent thereon.

            (c) A waiver of a Default under the Indenture by the Institutional
Trustee at the direction of the Holders of the Capital Securities, constitutes a
waiver of the corresponding 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
is hereby expressly excluded from this Declaration and the Securities, as
permitted by the Trust Indenture Act.

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

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

            (i) a default under Sections 5.7(b) and 5.7(c) of the Indenture; or

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

      account (the "Institutional Trustee Account") in the name of and under the
      exclusive control of the Institutional Trustee on behalf of the Holders of
      the Securities and, upon the receipt of payments of funds made in respect
      of the Debentures held by the Institutional Trustee, deposit such funds
      into the Institutional Trustee Account and make payments to the Holders of
      the Capital Securities and Holders of the Common Securities from the
      Institutional Trustee Account in accordance with Section 6.1. Funds in the
      Institutional Trustee Account shall be held uninvested until disbursed in
      accordance with this Declaration. The Institutional Trustee Account shall
      be an account that is maintained with a banking institution the rating on
      whose long-term unsecured indebtedness assigned 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 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 Capital Securities and the
      Common Securities to the extent the Debentures are redeemed or mature; and

            (iii) upon written notice of distribution issued by the Regular
      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 of Securities upon the
      occurrence of certain Special Events or other specified circumstances
      pursuant to the terms of the Securities.

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

            (e) Subject to Section 2.6, the Institutional Trustee shall take any
Legal Action which arises out of or in connection with a Default of which a
Responsible Officer of the Institutional Trustee has actual knowledge or the
Institutional Trustee's duties and obligations under this Declaration or the
Trust Indenture Act.

            (f) The Institutional Trustee shall not resign as a Trustee unless
either:

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

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

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

                                       15
<PAGE>

of the Debentures subject to the rights of the Holders pursuant to the terms of
such Securities, this Declaration, the Statutory Trust Act and the Trust
Indenture Act.

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

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

            The Institutional 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 the Institutional 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 Institutional Trustee.

            (a) The Institutional Trustee, before the occurrence of any Default
and after the curing of all Defaults that may have occurred, shall undertake to
perform only such duties as are specifically set forth in this Declaration and
no implied covenants shall be read into this Declaration against the
Institutional Trustee. In case a Default has occurred (that has not been cured
or waived pursuant to Section 2.6) of which a Responsible Officer of the
Institutional Trustee has actual knowledge, the Institutional Trustee shall
exercise such of the rights and powers vested in it by this Declaration, and use
the same degree of care and skill in the exercise of such rights and powers, 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 Institutional Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

            (i) prior to the occurrence of a Default and after the curing or
      waiving of all such Defaults that may have occurred:

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

                  (B) in the absence of bad faith on the part of the
            Institutional Trustee, the Institutional 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 Institutional Trustee and conforming to the
            requirements

                                       16
<PAGE>

            of this Declaration; but in the case of any such certificates or
            opinions that by any provision hereof are specifically required to
            be furnished to the Institutional Trustee, the Institutional Trustee
            shall be under a duty to examine the same to determine whether or
            not they conform to the requirements of this Declaration;

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

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

            (iv) no provision of this Declaration shall require the
      Institutional 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, if it shall have reasonable
      grounds for believing that the repayment of such funds or liability is not
      reasonably assured to it under the terms of this Declaration or indemnity
      reasonably satisfactory to the Institutional Trustee against such risk or
      liability is not reasonably assured to it;

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

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

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

      including such reasonable advances as may be requested by the
      Institutional Trustee provided that nothing contained in this Section

      powers vested in it by this Declaration;

            (vii) the Institutional Trustee shall not be bound to make any

there are more than two, a majority of the Regular Trustees and without the
consent of the Holders of the Securities, the Delaware Trustee or the
Institutional Trustee, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State; provided,
that:

            (i) such successor entity (the "Successor Entity") either:

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

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

            (ii) the Debenture Issuer expressly acknowledges a trustee of the
      Successor Entity that possesses the same powers and duties as the
      Institutional Trustee in its capacity as the Holder of the Debentures;

      or any Successor Securities will be listed upon notification of issuance,
      on any national

                                       20
<PAGE>

      securities exchange or with any other organization on which the Capital
      Securities are then listed or quoted;

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

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

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

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

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

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

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

            (viii) the Sponsor guarantees the obligations of such Successor
      Entity under the Successor Securities at least to the extent provided by
      the Capital Securities Guarantee.

            (c) Notwithstanding Section 3.15(b), the Trust shall not, except
with the consent of Holders of 100% in liquidation amount of the Securities,
consolidate, amalgamate, merge with or into, or be replaced by any other entity
or permit any other entity to consolidate, amalgamate, merge with or into, or
replace it, if in the opinion of a nationally recognized independent tax counsel
experienced in such matters, such consolidation, amalgamation, merger or
replacement would cause the Trust or the Successor Entity to be classified as
other than a grantor trust for United States federal income tax purposes.

            (a) There shall at all times be one Trustee that shall act as
Institutional Trustee which shall:

            (i) not be an Affiliate of the Sponsor;

      assets" of the Trust, the Institutional Trustee shall possess those
      qualifications.

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 annul the Trust. Whenever a vacancy in the number
of Regular Trustees shall occur, until such vacancy is filled by the appointment
of a Regular Trustee in accordance with Section 5.6, the Regular Trustees in
office, regardless of their number, shall have all the powers granted to the
Regular Trustees and shall discharge all the duties imposed upon the Regular
Trustees by this Declaration.

SECTION 5.9 Meetings.

            If there is more than one Regular Trustee, meetings of the Regular
Trustees shall be held from time to time upon the call of any Regular Trustee.
Regular meetings of the Regular Trustees may be held at a time and place fixed
by resolution of the Regular Trustees. Notice of any in-person meetings of the
Regular Trustees shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 48
hours before such meeting. Notice of any telephonic meetings of the Regular
Trustees or any committee thereof shall be hand delivered or otherwise delivered
in writing (including by facsimile, with a hard copy by overnight courier) not
less than 24 hours before a meeting. Notices shall contain a brief statement of
the time, place and anticipated purposes of the meeting. The presence (whether
in person or by telephone) of a Regular Trustee at a meeting shall constitute a
waiver of notice of such meeting except where a Regular 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 Regular Trustees may
be taken at a meeting by vote of a majority of the Regular 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 Regular Trustees. In the event there is only one Regular
Trustee, any and all action of such Regular Trustee shall be evidenced by a
written consent of such Regular Trustee.

SECTION 5.10 Delegation of Power.

            (a) Any Regular Trustee may, by power of attorney consistent with
applicable law, delegate to any other natural person over the age of 21 his or
her power for the purpose of executing any documents contemplated in Section
3.6, including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

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

                                       27
<PAGE>

            Any corporation into which the Institutional Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either may
be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Institutional Trustee or the Delaware Trustee, as the
case may be, shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Institutional Trustee or
the Delaware Trustee, as the case may be, shall be the successor of the
Institutional Trustee or the Delaware Trustee, as the case may be, hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

SECTION 6.1 Distributions.

            Holders shall receive Distributions (as defined herein) in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Capital Securities and the Common Securities
in accordance with the preferences set forth in their respective terms. If and
to the extent that the Debenture Issuer makes a payment of interest (including
Compounded Interest (as defined in the Indenture) and Additional Interest (as
defined in the Indenture)), premium and/or principal on the Debentures held by
the Institutional Trustee (the amount of any such payment being a "Payment
Amount"), the Institutional Trustee shall and is directed to make a distribution
(a "Distribution") of the Payment Amount to Holders.

                                   ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1 General Provisions Regarding Securities.

            (a) The Regular Trustees shall on behalf of the Trust issue one
class of capital securities representing undivided beneficial interests in the
assets of the Trust having such terms as are set forth in Annex I (the "Capital
Securities") and one class of common securities representing undivided
beneficial interests in the assets of the Trust having such terms as are set
forth in Annex I (the "Common Securities"). The Trust shall issue no securities
or other interests in the assets of the Trust other than the Capital Securities
and the Common Securities.

            (b) The Certificates shall be signed on behalf of the Trust by a
Regular Trustee. Such signature shall be the manual or facsimile signature of
any present or any future Regular Trustee. In case any Regular Trustee of the
Trust who shall have signed any of the Securities shall cease to be such Regular
Trustee before the Certificates so signed shall be delivered by the Trust, such
Certificates nevertheless may be delivered as though the person who signed such
Certificates had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Regular Trustees of the Trust, although
at the date of the execution and delivery of the Declaration any such person was
not such a Regular Trustee. Certificates shall be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Regular Trustees, as evidenced by their execution thereof, and may have such

                                       28
<PAGE>

letters, numbers or other marks of identification or designation and such
legends or endorsements as the Regular Trustees may deem appropriate, or as may
be required to comply with any law or with any rule or regulation of any stock
exchange on which Securities may be listed, or to conform to usage.

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

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

            (e) 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.

      of the Securities have been called for redemption and the amounts
      necessary for redemption thereof have been paid to the Holders in
      accordance with the terms of the Securities;

            (v) Subject to obtaining any required regulatory approval, when the
      Trust shall have been dissolved in accordance with the terms of the
      Securities upon election by the Sponsor of its right to terminate the
      Trust and distribute all of the Debentures to the Holders of Securities in
      exchange for all of the Securities and all of the Debentures shall have
      been distributed to the Holders of Securities in accordance with such
      election;

            (vi) before the issuance of any Securities, with the consent of all
      of the Regular Trustees and the Sponsor; or

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
the terms of the Securities. 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 shall be freely
transferable.

            (c) Subject to this Article IX, the Sponsor and any Related Party
may only transfer Common Securities to the Sponsor or a Related Party of the
Sponsor; provided, that any such transfer is subject to the condition precedent
that the transferor obtain the written opinion of nationally recognized
independent counsel experienced in such matters that such transfer would not
cause more than an insubstantial risk that:

            (i) the Trust would not be classified for United States federal
      income tax purposes as a grantor trust; and

            (ii) the Trust would be an Investment Company or the transferee
      would become an Investment Company.

SECTION 9.2 Transfer of Certificates.

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

SECTION 9.3 Deemed Security Holders.

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

SECTION 9.4 Book Entry Interests.

            Unless otherwise specified in the terms of the Capital Securities,
the Capital Securities Certificates, on original issuance, will be issued in the
form of one or more, fully registered, global Capital Security Certificates
(each a "Global Certificate"), to be delivered to DTC, the initial Clearing
Agency, by, or on behalf of, the Trust. Such Global Certificates shall initially
be registered on the books and records of the Trust in the name of Cede & Co.,
the nominee of DTC, and no Capital Security Beneficial Owner will receive a
definitive Capital Security Certificate representing such Capital Security
Beneficial Owner's interests in such Global Certificates, except as provided in
Section 9.7. Unless and until definitive, fully registered Capital Security
Certificates (the "Definitive Capital Security Certificates") have been issued

            (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

of the Global Certificates 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 between such Capital Security Beneficial
Owners and the Clearing Agency and/or the Clearing Agency Participants and
receive and transmit payments of Distributions on the Global Certificates to
such Clearing Agency Participants. DTC will 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 under this Declaration, unless and until Definitive Capital
Security Certificates shall have been issued to the Capital Security Beneficial
Owners pursuant to Section 9.7, the Regular Trustees shall give all such notices
and communications specified herein to be given to the Capital Security Holders
to the Clearing Agency, and shall have no notice obligations to the Capital
Security Beneficial Owners.

SECTION 9.6 Appointment of Successor Clearing Agency.

securities depositary with respect to the Capital Securities, the Regular
Trustees may, in their sole discretion, appoint a successor Clearing Agency with
respect to such Capital Securities.

SECTION 9.7 Definitive Capital Security Certificates.

            If:

            (a) a Clearing Agency elects to discontinue its services as a
securities depositary with respect to the Capital Securities and a successor
Clearing Agency is not appointed within 90 days after such discontinuance
pursuant to Section 9.6; or

            (b) the Regular Trustees elect after consultation with the Sponsor
to terminate the book entry system through the Clearing Agency with respect to
the Capital Securities,

then:

            (c) Definitive Capital Security Certificates shall be prepared by
the Regular Trustees on behalf of the Trust with respect to such Capital
Securities; and

            (d) upon surrender of the Global Certificates by the Clearing
Agency, accompanied by registration instructions, the Regular Trustees shall
cause Definitive Certificates to be delivered to Capital Security Beneficial
Owners in accordance with the instructions of the Clearing Agency. Neither the
Trustees nor the Trust shall be liable for any delay in delivery of such
instructions and each of them may conclusively rely on and shall be protected in
relying on, said instructions of the Clearing Agency. The Definitive Capital
Security Certificates shall be printed, lithographed or engraved or may be
produced in any other manner as is reasonably acceptable to the Regular
Trustees, as evidenced by their execution thereof, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements as the Regular Trustees may deem appropriate, or as may be required
to comply with any law or with any rule or regulation made pursuant thereto or
with any rule or regulation of any stock exchange on which Capital Securities
may be listed, or to conform to usage.

SECTION 9.8 Mutilated, Destroyed, Lost or Stolen Certificates.

If:

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

            (b) there shall be delivered to the Regular Trustees such security
or indemnity as may be required by them to keep each of them harmless.

then, in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any Regular Trustee on behalf of the Trust shall execute
and deliver, in exchange for

                                       32
<PAGE>

or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like denomination. In connection with the issuance of any new
Certificate under this Section 9.8, the Regular Trustees may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection therewith. Any duplicate Certificate issued pursuant to
this Section shall constitute conclusive evidence of an ownership interest in
the relevant Securities, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

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

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

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

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

SECTION 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
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

                                       33
<PAGE>

reasonable care by or on behalf of the Trust, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any other facts pertinent to the existence and amount of
assets from which Distributions to Holders of Securities might properly be paid.

SECTION 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 Institutional 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 Persons; 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 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.

                                       34
<PAGE>

            (a)   (i) The Debenture Issuer 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), 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 Debenture Issuer 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) 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.

            (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 Debenture
      Issuer 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 Regular Trustees by a majority vote of a quorum consisting of such
      Regular 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 Regular Trustees so directs, by

                                       35
<PAGE>

      independent legal counsel in a written opinion, or (3) by the Common
      Security Holder of the Trust.

            (v)   Expenses (including attorneys' fees) 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 Debenture Issuer in
      advance of the final disposition of such action, suit or proceeding upon
      receipt of an undertaking by or on behalf of such Company Indemnified
      Person to repay such amount if it shall ultimately be determined that he
      is not entitled to be indemnified by the Debenture Issuer as authorized in
      this Section 10.4(a). Notwithstanding the foregoing, no advance shall be
      made by the Debenture Issuer if a determination is reasonably and promptly
      made (i) by the Regular Trustees by a majority vote of a quorum of
      disinterested Regular Trustees, (ii) if such a quorum is not obtainable,
      or, even if obtainable, if a quorum of disinterested Regular Trustees so
      directs, by independent legal counsel in a written opinion or (iii) the
      Common Security Holder of the Trust, that, based upon the facts known to
      the Regular 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 such person did not believe to be in or not
      opposed to the best interests of the Trust, or, with respect to any
      criminal proceeding, that such 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 Regular Trustees, independent
      legal counsel or Common Security Holder reasonably determine that such
      person deliberately breached his duty to the Trust or its Common or
      Capital Security Holders.

            (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
      Debenture Issuer or Capital Security Holders of the Trust or otherwise,
      both as to action in his official capacity and as to action in another
      capacity while holding such office. All rights to indemnification under
      this Section 10.4(a) shall be deemed to be provided by a contract between
      the Debenture Issuer and each Company Indemnified Person who serves in
      such capacity at any time while this Section 10.4(a) is in effect. Any
      repeal or modification of this Section 10.4(a) shall not affect any rights
      or obligations then existing.

            (vii) The Debenture Issuer 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

                                       36
<PAGE>

      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 Debenture Issuer agrees to indemnify the (i) Institutional
Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Institutional
Trustee and the Delaware Trustee, and (iv) any officers, directors,
shareholders, members, partners, employees, representatives, custodians,
nominees or agents of the Institutional Trustee and the Delaware Trustee (each
of the Persons in (i) through (iv) being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any loss, liability or expense incurred without negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration or
the trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against or investigating
any claim or liability in connection with the exercise or performance of any of
its powers or duties hereunder. The obligation to indemnify as set forth in this
Section 10.4(b) shall survive the resignation or removal of the Institutional
Trustee or the Delaware Trustee, as the case may be, and the satisfaction and
discharge of this Declaration.

SECTION 10.5 Outside Businesses.

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

                                   ARTICLE XI

SECTION 11.1 Fiscal Year.

                                       37
<PAGE>

            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 Regular
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 Regular Trustees.

            (b)   The Regular Trustees shall cause to be prepared and delivered
to each of the Holders of Securities, to the extent, if any, required by the
Trust Indenture Act, within 90 days after the end of each Fiscal Year of the
Trust, annual financial statements of the Trust, including a balance sheet of
the Trust as of the end of such Fiscal Year, and the related statements of
income or loss;

            (c)   The Regular Trustees shall cause to be duly prepared and
delivered to each of the Holders of Securities, 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 deliver any such statement at a later date, the Regular Trustees shall
endeavor to deliver all such statements within 30 days after the end of each
Fiscal Year of the Trust.

            (d)   The Regular 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 Regular Trustees on behalf of the Trust with any state or local taxing
authority.

SECTION 11.3 Banking.

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

SECTION 11.4 Withholding.

            The Trust and the Regular 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

                                       38
<PAGE>

shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations. The Regular Trustees
shall file required forms with applicable jurisdictions and, unless an exemption
from withholding is properly established by a Holder, shall remit amounts
withheld with respect to the Holder to applicable jurisdictions. To the extent
that the Trust is required to withhold and pay over any amounts to any authority
with respect to distributions or allocations to any Holder, the amount withheld
shall be deemed to be a distribution in the amount of the withholding to the
Holder. In the event of any claimed overwithholding, Holders shall be limited to
an action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

                                   ARTICLE XII

SECTION 12.2 Meetings of the Holders of Securities; Action by Written Consent.

                                       40
<PAGE>

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

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

            (i)   notice of any such meeting shall be given to all the Holders
      of Securities having a right to vote thereat at least 7 days and not more
      than 60 days before the date of such meeting. Whenever a vote, consent or
      approval of the Holders of Securities is permitted or required under this
      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 of Securities. Any
      action that may be taken at a meeting of the Holders of Securities may be
      taken without a meeting if a consent in writing setting forth the action
      so taken is signed by the Holders of Securities owning not less than the
      minimum amount of Securities in liquidation amount that would be necessary
      to authorize or take such action at a meeting at which all Holders of
      Securities having a right to vote thereon were present and voting. Prompt
      notice of the taking of action without a meeting shall be given to the
      Holders of Securities entitled to vote who have not consented in writing.
      The Regular 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 Regular
      Trustees;

            (ii)  each Holder of a Security may authorize any Person to act for
      it by proxy on all matters in which a Holder of Securities is entitled to
      participate, including waiving notice of any meeting, or voting or
      participating at a meeting. No proxy shall be valid after the expiration
      of 11 months from the date thereof unless otherwise provided in the proxy.
      Every proxy shall be revocable at the pleasure of the Holder of Securities
      executing it. Except as otherwise provided herein, all matters relating to

      and the Holders of the Securities were stockholders of a Delaware
      corporation;

            (iii) each meeting of the Holders of the Securities shall be
      conducted by the Regular Trustees or by such other Person that the Regular

      the Securities, the Trust Indenture Act or the listing rules of any stock

      otherwise provides, the Regular Trustees, in their sole discretion, shall
      establish all other provisions relating to meetings of Holders of
      Securities, including notice of the time, place or purpose of any meeting
      at which any matter is to be voted on by any Holders of Securities, waiver

                                     ANNEX I

                                    TERMS OF
                              % CAPITAL SECURITIES
                               % COMMON SECURITIES

            Pursuant to Section 7.1 of the Amended and Restated Declaration of
Trust, dated as of      , 20  (as amended from time to time, the "Declaration"),
the designation, rights, privileges, restrictions, preferences and other terms
and provisions of the Capital Securities and the Common 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 Prospectus referred to below):

            1.    Designation and Number.

            (a)   Capital Securities.  Capital Securities of the Trust (or up to
Capital Securities if the over-allotment option is exercised pursuant to Section
of the Underwriting Agreement) with an aggregate liquidation amount with respect
to the assets of the Trust of       dollars ($      ) (or up to
($      ) if the over-allotment option is exercised pursuant to Section of the
Underwriting Agreement), and a liquidation amount with respect to the assets of
the Trust of $ per capital security, are hereby designated for the purposes of
identification only as "   % Capital Securities" (the "Capital Securities"). The
Capital Security 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 stock exchange on
which the Capital Securities are listed.

            (b)   Common Securities.   Common Securities of the Trust (or up to
Common Securities if the over-allotment option is exercised pursuant to Section
of the Underwriting Agreement) with an aggregate liquidation amount with respect
to the assets of the Trust of       dollars ($      ) (or up to
($        ) if the over-allotment option is exercised pursuant to Section of the
Underwriting Agreement), and a liquidation amount with respect to the assets of
the Trust of $ per common security, are hereby designated for the purposes of
identification only as "   % Common Securities" (the "Common Securities"). The
Common Security 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 payable on each Security will be fixed at a rate
per annum of % (the "Coupon Rate") of the stated liquidation amount of $ per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Institutional Trustee. Distributions in arrears beyond the first
date such Distributions are payable (or would be payable, if not for any
Extension Period (as defined below) or default by the Debenture Issuer on the
Debentures) will bear interest thereon compounded quarterly at the Coupon Rate
(to the extent permitted by

                                      I-1
<PAGE>

applicable law). The term "Distributions" as used herein includes such cash
distributions and any such interest payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Institutional Trustee and to the extent the
Institutional Trustee has funds available therefor. The amount of Distributions
payable for any period will be computed for any full quarterly Distribution
period on the basis of a 360-day year of twelve 30-day months, and for any
period shorter than a full quarterly Distribution period for which Distributions
are computed, Distributions will be computed on the basis of the actual number
of days elapsed per 90-day quarter.

            (b)   Distributions on the Securities will be cumulative, will
accrue from and including   , 20 , and will be payable quarterly in arrears, on
   ,   , and of each year, commencing on    , 20 . When, as and if available for
payment, Distributions will be made by the Institutional Trustee, except as
otherwise described below. The Debenture Issuer has the right under the
Indenture to defer payments of interest on the Debentures by extending the
interest payment period from time to time on the Debentures for a period not
exceeding 20 consecutive quarters (each an "Extension Period"), during which
Extension Period no interest shall be due and payable on the Debentures,
provided, that no Extension Period may extend beyond the date of maturity of the
Debentures. As a consequence of the Debenture Issuer's extension of the interest
payment period, quarterly Distributions will also be deferred. Despite such
deferral, quarterly Distributions will continue to accrue with interest thereon
(to the extent permitted by applicable law) at the Coupon Rate compounded
quarterly during any such Extension Period. In the event that the Debenture
Issuer exercises its right to extend the interest payment period, then (a) the
Debenture Issuer shall not declare or pay any dividend on, make any
distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock or make any
guarantee payment with respect thereto (other than (i) repurchases, redemptions
or other acquisitions of shares of capital stock of Citigroup in connection with
any employment contract, benefit plan or other similar arrangement with or for
the benefit of employees, officers, directors or consultants, (ii) as a result
of an exchange or conversion of any class or series of Citigroup's capital stock
for any other class or series of Citigroup's capital stock, or (iii) the
purchase of fractional interests in shares of Citigroup's capital stock pursuant
to the conversion or exchange provisions of such capital stock or the security
being converted or exchanged) and (b) the Debenture Issuer shall not make any
payment of interest on or principal of (or premium, if any, on), or repay,
repurchase or redeem, any debt securities issued by the Debenture Issuer that
rank pari passu with or junior to the Debentures. The foregoing, however, will
not apply to any stock dividends paid by Citigroup where the dividend stock is
the same stock as that on which the dividend is being paid. Prior to the
termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided, that such Extension Period, together
with all such previous and further extensions thereof, may not exceed 20
consecutive quarters; provided further, that no Extension Period may extend
beyond the maturity of the Debentures. Payments of deferred Distributions and
accrued interest thereon will be payable to Holders as they appear on the books
and records of the Trust on the first record date after 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. The Regular Trustees will give notice to each
Holder of any Extension Period upon their receipt of notice thereof from the
Debenture Issuer.

                                      I-2
<PAGE>

            (c)   Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust at the close of
business on the relevant record dates. While the Capital Securities remain in
book-entry only form, the relevant record dates shall be one Business Day prior
to the relevant payment dates which payment dates shall correspond to the
interest payment dates on the Debentures. Subject to any applicable laws and
regulations and the provisions of the Declaration, each such payment in respect
of the Capital Securities will be made as described under the heading
"Description of the Capital Securities -- Book-Entry Only Issuance" in the
Prospectus dated     , 20 (the "Prospectus"), of the Trust included in the
Registration Statement on Form S-3 of the Sponsor, the Trust and certain other
statutory trusts. The relevant record dates for the Common Securities shall be
the same record date as for the Capital Securities. If the Capital Securities
shall not continue to remain in book-entry only form, the relevant record dates
for the Capital Securities shall conform to the rules of any securities exchange
on which the securities are listed and, if none, shall be selected by the
Regular Trustees, which dates shall be more than 14 days but less than 60 days
prior to the relevant payment dates, which payment dates shall correspond to the
interest payment dates on the Debentures. Distributions payable on any
Securities that are not punctually paid on any Distribution payment date, as a
result of the Debenture Issuer having failed to make a payment under the
Debentures, will cease to be payable to the Person in whose name such Securities
are registered on the relevant record date, and such defaulted Distribution will
instead be payable to the Person in whose name such Securities are registered on
the special record date or other specified date determined in accordance with
the Indenture. If any date on which Distributions are payable on the Securities
is not a Business Day, then payment of the Distribution payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case 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 of the Securities.

            3.    Liquidation Distribution Upon Dissolution.

            (a)   In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust, the Holders of the Securities on the
date of the dissolution, winding-up or termination, as the case may be, will be
entitled to receive out of the assets of the Trust available for distribution to
Holders of Securities after satisfaction of liabilities of creditors,
distributions in an amount equal to the aggregate of the stated liquidation
amount of $ per Security plus accrued and unpaid Distributions thereon to the
date of payment (such amount being the "Liquidation Distribution"), unless, in
connection with such dissolution, winding-up or termination, Debentures in an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate equal to the Coupon Rate, and bearing accrued and unpaid
interest in an amount equal to the accrued and unpaid Distributions on, such
Securities outstanding at such time, have been distributed on a Pro Rata basis
to the Holders of the Securities in exchange for such Securities. Prior to any
such Liquidation Distribution, the Debenture Issuer will obtain any required
regulatory approval.

                                      I-3
<PAGE>

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

            4.    Redemption and Distribution.

            (a)   Upon the repayment of the Debentures in whole or in part,
whether at maturity or upon redemption (either at the option of the Debenture
Issuer or pursuant to a Special Event as described below), the proceeds from
such repayment or payment shall be simultaneously applied to redeem Securities
having an aggregate liquidation amount equal to the aggregate principal amount
of the Debentures so repaid or redeemed at a redemption price of $ per Security
plus an amount equal to accrued and unpaid Distributions thereon at the date of
the redemption, payable in cash (the "Redemption Price"). Holders shall be given
not less than 30 nor more than 60 days' notice of such redemption. Prior to any
such redemption, the Debenture Issuer will obtain any required regulatory
approval.

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

            (c)   Subject to obtaining any required regulatory approval, if, at
any time, a Tax Event, an Investment Company Event or a Regulatory Capital Event
(each as defined below, and each a "Special Event") shall occur and be
continuing, Citigroup shall have the right, upon not less than 30 nor more than
60 days' notice, to redeem the Debentures, in whole or in part, for cash within
90 days following the occurrence of such Special Event, and, following such
redemption, Securities with an aggregate liquidation amount equal to the
aggregate principal amount of the Debentures so redeemed shall be redeemed by
the Trust at the Redemption Price on a Pro Rata basis; provided, however, that
if at the time there is available to Citigroup or the Trust the opportunity to
eliminate, within such 90-day period, the Special Event by taking some
ministerial action, such as filing a form or making an election or pursuing some
other similar reasonable measure that will have no adverse effect on the Trust,
Citigroup or the holders of the Securities, then Citigroup or the Trust will
pursue such measure in lieu of redemption.

            "Tax Event" means that the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters (a "Tax Event Opinion") 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 amendment to, or
change in, an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority (including
the enactment of any legislation and the publication of any judicial decision or
regulatory determination on or after the date of the Prospectus), in either case
after the date of the Prospectus, there is more than an insubstantial risk that
(i) the Trust would be subject to United States federal income tax with respect
to interest accrued or received on the Debentures, (ii) the Trust would be
subject to more than a de minimis amount of other taxes, duties or other
governmental charges, or (iii) interest payable to the Trust

                                      I-4

<PAGE>

on the Debentures would not be deductible, in whole or in part, by the Debenture
Issuer for United States federal income tax purposes.

            "Investment Company Event" means that the Regular Trustees shall
have received an opinion of a nationally recognized independent counsel
experienced in practice under the Investment Company Act (an "Investment Company
Event Opinion") to the effect that, as a result of the occurrence of a change in
law or regulation or a written change in interpretation or application of law or
regulation by any legislative body, court, governmental agency or regulatory
authority (a "Change in 1940 Act Law"), there is a more than an insubstantial
risk that the Trust is or will be considered an Investment Company which is
required to be registered under the Investment Company Act, which Change in 1940
Act Law becomes effective on or after the date of the Prospectus.

            "Regulatory Capital Event" means a determination by Citigroup, based
on an opinion of counsel experienced in such matters (who may be an employee of
Citigroup or any of its affiliates), that, as a result of (a) any amendment to,
clarification of or change (including any announced prospective change) in
applicable laws or regulations or official interpretations thereof or policies
with respect thereto or (b) any official administrative pronouncement or
judicial decision interpreting or applying such laws or regulations, which
amendment, clarification, change, pronouncement or decision is announced or is
effective after the date of the Prospectus, there is more than an insubstantial
risk that the Capital Securities will no longer constitute Tier I Capital of
Citigroup or any bank holding company of which Citigroup is a subsidiary (or its
equivalent) for purposes of the capital adequacy guidelines or policies of the
Board of Governors of the Federal Reserve System or its successor as Citigroup's
primary federal banking regulator.

            On and from the date fixed by the Regular Trustees for any
distribution of the Debentures and dissolution of the Trust: (i) the Securities
will no longer be deemed to be outstanding, (ii) DTC or its nominee (or any
successor Clearing Agency or its nominee), as the record 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, except for certificates representing
Capital Securities held by DTC or its nominee (or any successor Clearing Agency
or its nominee), will be deemed to represent beneficial interests in the
Debentures having an aggregate principal amount equal to the aggregate stated
liquidation amount of, with an interest rate identical to the Coupon Rate of,
and accrued and unpaid interest equal to accrued and unpaid Distributions on
such Securities until such certificates are presented to the Debenture Issuer or
its agent for transfer or reissue.

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

            (e) If the Debentures are distributed to the Holders of the
Securities, pursuant to the terms of the Indenture, the Debenture Issuer will
use its best efforts to cause the Debentures to be listed on the New York Stock
Exchange or on such other exchange as the Capital Securities were listed
immediately prior to the distribution of the Debentures.

            (f) Redemption or Distribution procedures will 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 of the
      Securities to be redeemed or exchanged not fewer than 30 nor more than 60
      days before the date fixed for redemption or exchange thereof which, in
      the case of a redemption, will be the date fixed for redemption of the
      Debentures. For purposes of the calculation of the date of redemption or
      exchange and the dates on which notices are given pursuant to this Section
      4(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 the Holders of the Securities. Each Redemption/Distribution Notice
      shall be addressed to the Holders of the Securities 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 Securities to be redeemed shall be redeemed Pro Rata
      from each Holder of Capital Securities, it being understood that, in
      respect of Capital Securities registered in the name of and held of record
      by DTC or its nominee (or any successor Clearing Agency or its nominee),
      the distribution of the proceeds of such redemption will be made to each
      Clearing Agency Participant (or Person on whose behalf such nominee holds
      such securities) 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 may only be issued if the
      Debentures are redeemed as set out in this Section 4 (which notice will be
      irrevocable), then (A) while the Capital Securities are in book-entry only
      form, with respect to the Capital Securities, by 12:00 noon, New York City
      time, on the redemption date, provided, that the Debenture Issuer has paid
      to the Institutional Trustee a sufficient amount of cash in connection
      with the related redemption or maturity of the Debentures, the
      Institutional Trustee will deposit irrevocably with DTC or its nominee (or
      successor Clearing Agency or its nominee) funds sufficient to pay the
      applicable Redemption Price with respect to the Capital Securities and
      will give DTC (or any successor Clearing Agency) irrevocable instructions
      and authority to pay the Redemption Price to the Holders of the Capital
      Securities, and (B) with respect to Capital Securities issued in
      definitive form and Common Securities, provided, that the Debenture Issuer
      has paid the Institutional Trustee a sufficient amount of cash in
      connection with the related redemption or maturity of the Debentures, the
      Institutional Trustee will pay the relevant Redemption Price to the
      Holders of such Securities by check mailed to the address of the relevant
      Holder appearing on the books and records of the Trust on the redemption
      date. If a Redemption/Distribution Notice shall have been given and funds
      deposited as required, 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 accrue on the Securities so called
      for redemption and all rights of the Holders of such Securities so called
      for redemption will cease, except the right of the Holders of such
      Securities to receive the

                                      I-6

<PAGE>

      Redemption Price, but without interest on such Redemption Price. Neither
      the Regular Trustees nor the Trust shall be required to register or cause
      to be registered the transfer of any Securities that have been so called
      for redemption. 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) except
      that, if such Business Day falls in the next calendar year, such payment
      will be made on the immediately preceding Business Day, in each case with
      the same force and effect as if made on such date fixed for redemption. If
      payment of the Redemption Price in respect of any Securities is improperly
      withheld or refused and not paid either by the Institutional Trustee or by
      the Sponsor as guarantor pursuant to the relevant Securities Guarantee,
      Distributions on such Securities will continue to accrue 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.

            (iv) Redemption/Distribution Notices shall be sent by the Regular
      Trustees on behalf of the Trust to (A) in respect of the Capital
      Securities, DTC or its nominee (or any successor Clearing Agency or its
      nominee) if the Global Certificates have been issued or, if Definitive
      Capital Security Certificates have been issued, to the Holder thereof and
      (B) in respect of the Common Securities to the Holder thereof.

            (v) Subject to the foregoing and applicable law (including, without
      limitation, United States federal securities laws), the Debenture Issuer
      or its affiliates 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) and 7 and as otherwise
required by law and the Declaration, the Holders of the Capital Securities will
have no voting rights.

            (b) Subject to the requirements set forth in this paragraph, the
Holders of a Majority in aggregate liquidation amount of the Capital Securities,
voting separately as a class, may direct the time, method, and place of
conducting any proceeding for any remedy available to the Institutional Trustee,
or direct the exercise of any trust or power conferred upon the Institutional
Trustee under the Declaration, including the right to direct the Institutional
Trustee, as holder of the Debentures, to (i) direct the time, method and place
of conducting any proceeding for any remedy available to the Debenture Trustee,
or exercise any trust or power conferred on the Debenture Trustee with respect
to the Debentures, (ii) waive any past Default (as defined in the Indenture)
that is waivable under Section 5.6 of the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Debentures shall be
due and payable or (iv) consent to any amendment, modification or termination of
the Indenture or the Debentures where such consent shall be required; provided,
however, that, where a consent or action under the Indenture would require the
consent or act of each holder of each Debenture affected thereby, such consent
or action under the Indenture shall not be effective until each Holder of
Capital Securities shall have consented to such action or provided such consent.
The Institutional Trustee shall not revoke any action previously authorized or
approved by a vote of

                                      I-7

<PAGE>

the Holders of the Capital Securities. Except with respect to directing the
time, method and place of conducting a proceeding for a remedy available to the
Institutional Trustee, the Institutional Trustee, as holder of the Debentures,
shall not take any of the actions described in clauses (i), (ii), (iii) or (iv)
above unless the Institutional Trustee has obtained an opinion of a nationally
recognized independent tax counsel experienced in such matters to the effect
that as a result of such action, the Trust will not fail to be classified as a
grantor trust for United States federal income tax purposes. If the
Institutional Trustee fails to enforce its rights under the Debentures, any
Holder of Capital Securities may directly institute a legal proceeding against
the Debenture Issuer to enforce the Institutional Trustee's rights under the
Debentures without first instituting a legal proceeding against the
Institutional Trustee or any other Person or entity. If a Default under the
Declaration has occurred and is continuing and such event is attributable to the
failure of the Debenture Issuer to pay interest or principal on the Debentures
on the date such interest or principal is otherwise payable (or in the case of
redemption, on the redemption date), then a holder of Capital Securities may
also directly institute a proceeding for enforcement of payment to such holder
(a "Direct Action") of the principal of or interest on the Debentures having a
principal amount equal to the aggregate liquidation amount of the Capital
Securities of such holder on or after the respective due date specified in the
Debentures without first (i) directing the Institutional Trustee to enforce the
terms of the Debentures or (ii) instituting a legal proceeding directly against
the Debenture Issuer to enforce the Institutional Trustee's rights under the
Debentures. Except as provided in the preceding sentence, the Holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures. In connection with such Direct Action, Citigroup
will be subrogated to the rights of such Holder of Capital Securities under the
Declaration to the extent of any payment made by Citigroup to such holder of
Capital Securities in such Direct Action.

            Any required approval or direction of Holders of Capital Securities
may be given at a separate meeting of Holders of Capital Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Capital Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of 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 consents.

            No vote or consent of the Holders of the Capital Securities will be
required for the Trust to redeem and cancel Capital Securities or to distribute
the Debentures in accordance with this 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), (c) and 7 as otherwise
required by law and the Declaration, the Holders of the Common Securities will
have no voting rights.

            (b) The Holders of the Common Securities are entitled, in accordance
with and subject to Article V of the Declaration, to vote to appoint, remove or
replace any Trustee or to increase or decrease the number of Trustees.

            (c) Subject to Section 2.6 of the Declaration and only after the
Default with respect to the Capital Securities has been cured, waived, or
otherwise eliminated and subject to the requirements of the second to last
sentence of this paragraph, the Holders of a Majority in liquidation amount of
the Common Securities, voting separately as a class, may direct the time,
method, and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or direct the exercise of any trust or power conferred
upon the Institutional Trustee under the Declaration, including (i) directing
the time, method, place of conducting any proceeding for any remedy available to
the Debenture Trustee, or exercising any trust or power conferred on the
Debenture Trustee with respect to the Debentures, (ii) waiving any past Default
(as defined in the Indenture) that is waivable under Section 5.6 of the
Indenture, or (iii) exercising any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable, provided that,
where a consent or action under the Indenture would require the consent or act
of the Holders of greater than a majority in principal amount of Debentures
affected thereby (a "Super Majority"), the Institutional Trustee may only give
such consent or take such action at the written direction of the Holders of at
least the proportion in liquidation amount of the Common Securities which the
relevant Super Majority represents of the aggregate principal amount of the
Debentures outstanding. Pursuant to this Section 6(c), the Institutional Trustee
shall not revoke any action previously authorized or approved by a vote of the
Holders of the Capital Securities. Other than with respect to directing the
time, method and place of conducting any proceeding for any remedy available to
the Institutional Trustee or the Debenture Trustee as set forth above, the
Institutional Trustee shall not take any action in accordance with the
directions of the Holders of the Common Securities under this paragraph unless
the Institutional Trustee has obtained an opinion of tax counsel to the effect
that for the purposes of United States federal income tax the Trust will not be
classified as other than a grantor trust on account of such action. If the
Institutional Trustee fails to enforce its rights under the Declaration, any
Holder of Common Securities may institute a legal proceeding directly against
any Person to enforce the Institutional Trustee's rights under the Declaration,
without first instituting a legal proceeding against the Institutional Trustee
or any other Person.

            Any approval or direction of Holders of 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 Regular 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

                                      I-9
<PAGE>

Holders are entitled to vote or of such matter upon which written consent is
sought and (iii) instructions for the delivery of proxies or consents.

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

            7. Amendments to Declaration and Indenture.

            (a) In addition to any requirements under Section 12.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities as a
class, will be entitled to vote on such amendment or proposal (but not on any
other amendment or proposal) and such amendment or proposal shall not be
effective except with the approval of the Holders of at least a Majority in
liquidation amount of the Securities, voting together as a single class;
provided, however, if any amendment or proposal referred to in clause (i) above
would adversely affect only the Capital Securities or only the Common
Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a Majority in liquidation amount of such class of
Securities.

            (b) In the event the consent of the Institutional Trustee as the
holder of the Debentures is required under the Indenture with respect to any
amendment, modification or termination on the Indenture or the Debentures, the
Institutional Trustee shall request the written direction of the Holders of the
Securities with respect to such amendment, modification or termination and shall
vote with respect to such amendment, modification or termination as directed by
a Majority in liquidation amount of the Securities voting together as a single
class; provided, however, that where a consent under the Indenture would require
the consent of the holders of greater than a majority in aggregate principal
amount of the Debentures (a "Super Majority"), the Institutional Trustee may
only give such consent at the direction of the Holders of at least the
proportion in liquidation amount of the Securities which the relevant Super
Majority represents of the aggregate principal amount of the Debentures
outstanding; provided, further, that the Institutional Trustee shall not take
any action in accordance with the directions of the Holders of the Securities
under this Section 7(b) unless the Institutional Trustee has obtained an opinion
of tax counsel to the effect that for the purposes of United States federal
income tax the Trust will not be classified as other than a grantor trust on
account of such action.

            8. Pro Rata.

            A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate liquidation amount of the Securities
held by the relevant Holder in relation to the aggregate liquidation amount of
all Securities outstanding unless, in relation to a payment, an a 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

                                      I-10

<PAGE>

according to the aggregate liquidation amount of Capital Securities held by the
relevant Holder relative to the aggregate liquidation amount of all Capital
Securities outstanding, and only after satisfaction of all amounts owed to the
Holders of the Capital Securities, to each Holder of Common Securities pro rata
according to the aggregate liquidation amount of Common Securities held by the
relevant Holder relative to the aggregate liquidation amount of all Common
Securities outstanding.

            9. Ranking.

            The Capital Securities rank pari passu and payment thereon shall be
made Pro Rata with the Common Securities except that, where a Default (as
defined in the Indenture) occurs and is continuing under the Indenture in
respect of the Debentures held by the Institutional Trustee, the rights of
Holders of the Common Securities to payment in respect of Distributions and
payments upon liquidation, redemption and otherwise are subordinated to the
rights to payment of the Holders of the Capital Securities.

            10. Listing.

            The Regular Trustees shall use their best efforts to cause the
Capital Securities to be listed on the New York Stock Exchange.

            11. Acceptance of Securities Guarantee and Indenture.

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

            12. No Preemptive Rights.

            The Holders of the Securities shall have no preemptive rights to
subscribe for any additional securities.

            13. Miscellaneous.

            These terms constitute a part of the Declaration.

            The Sponsor will provide a copy of the Declaration or the Capital
Securities Guarantee, and the Indenture to a Holder without charge on written
request to the Sponsor at its principal place of business.
