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

provided further, each Holder of Common Securities will be deemed to have waived
- -------- -------
any such Event of Default and all Events of Default with respect to the Common
Securities and their consequences if all Events of Default with respect to the
Capital Securities have been cured, waived or otherwise eliminated, and until
such Events of Default have been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the Holders of
the Capital Securities and only the Holders of the Capital Securities will have
the right to direct the Property Trustee in accordance with the terms of the
Securities.  The foregoing provisions of this Section 2.6(b) shall be in lieu of
(S)(S) 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such (S)(S)
316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby expressly
excluded from this Declaration and the Securities, as permitted by the Trust
Indenture Act.  Subject to the foregoing provisions of this Section 2.6(b), upon
such waiver, any such Default shall cease to exist and any Event of Default with
respect to the Common Securities arising therefrom shall be deemed to have been
cured for every purpose of this Declaration, but no such waiver shall extend to
any subsequent or other Default or Event of Default with respect to the Common
Securities or impair any right consequent thereon.

          (c)  A waiver of an Event of Default under the Indenture by the
Property Trustee, at the direction of the Holders of the Capital Securities,
constitutes a waiver of the

                                       12


corresponding Event of Default under this Declaration. The foregoing provisions
of this Section 2.6(c) shall be in lieu of (S) 316(a)(1)(B) of the Trust
Indenture Act and such (S) 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 Property Trustee shall, within 90 days after a
Responsible Officer has actual knowledge of the occurrence of a Default with
respect to the Securities, transmit by mail, first class postage prepaid, to the
Holders, notices of all such Defaults, unless such Defaults have been cured
before the giving of such notice or previously waived; provided, however, that
                                                       --------  -------
except in the case of a Default arising from the nonpayment of principal of or
interest (including Compounded Interest and Additional Sums (as such terms are
defined in the Indenture), if any) or Liquidated Damages, if any (as defined in
the Registration Rights Agreement), on any of the Debentures, the Property
Trustee shall be protected in withholding such notice if and so long as a
Responsible Officer in good faith determines that the withholding of such notice
is in the interests of the Holders.

               (b)  The Property Trustee shall not be deemed to have knowledge
of any Default or Event of Default except:

                    (i)    a Default or Event of Default under Sections 5.1(a)
               (other than the payment or nonpayment of Compounded Interest,
               Additional Sums and Liquidated Damages) and 5.1(b) of the
               Indenture; or

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

               (c)  Within ten Business Days after a Responsible Officer has
actual knowledge of the occurrence of any Event of Default, the Property Trustee
shall transmit notice of such Event of Default to the Holders of the Capital
Securities, the Administrative Trustees and the Sponsor, unless such Event of
Default shall have been cured or waived. The Sponsor and the Administrative
Trustees shall file annually with the Property Trustee a certification as to
whether or not they are in compliance with all the conditions and covenants
applicable to them under this Declaration.

               ----------------------------------------------------

               The Trust shall not, and the Trustees (including the Property
Trustee and the Delaware Trustee) shall not, and the Administrative Trustees
shall cause the Trust not to, engage in any activity other than as required or
authorized by this Declaration. Notwithstanding any provision in this
Declaration to the contrary, the Trust shall not:

                    (i)    invest any proceeds received by the Trust from
               holding the Debentures, but shall distribute all such proceeds to

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

                                       17


                    (iii)  possess Trust Property for other than a Trust purpose
               or execute any mortgage in respect of, or pledge, any Trust
               Property;

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

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

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

               hereto, (A) direct the time, method and place of conducting any
               proceeding with respect to any remedy available to the Debenture

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

SECTION 3.8    Powers and Duties of the Property Trustee.
               -----------------------------------------

               (a)  The legal title to the Debentures shall be owned by and held
of record in the name of the Property Trustee in trust for the benefit of the
Trust and the Holders. The right, title and interest of the Property Trustee to
the Debentures shall vest automatically in each Person who may hereafter be

cessation of title shall be effective whether or not conveyancing documents with
regard to the Debentures have been executed and delivered.

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

               (c)  The Property Trustee shall:

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

                                       18


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

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

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

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

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

                                       19


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

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

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

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

2.7(b) hereof, a Responsible Officer of the Property Trustee has actual
knowledge) and after the curing or waiving of all such Events of Default that
may have occurred, shall undertake to perform only such duties as are
specifically set forth in this Declaration and in the Securities and no implied
covenants shall be read into this Declaration against the Property Trustee. In
case an Event of Default has occurred (that has not been cured or waived
pursuant to Section 2.6) of which a Responsible Officer has actual knowledge,
the Property Trustee shall exercise such of the rights and powers vested in it
by this Declaration, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

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

                    (i)    prior to the occurrence of an Event of Default (of
               which, other than in the case of Events of Default under Sections

               is deemed to have knowledge of as provided in Section 2.7(b)
               hereof, a Responsible Officer of the Property Trustee has actual
               knowledge) and after the curing or waiving of all such Events of
               Default that may have occurred:

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

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

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

                    (iii)  the Property Trustee shall not be liable with respect
               to any action taken or omitted to be taken by it in good faith in
               accordance with the

                                       21

               the Securities relating to the time, method and place of
               conducting any proceeding for any remedy available to the
               Property Trustee, or exercising any trust or power conferred upon
               the Property Trustee under this Declaration;

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

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

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

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

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

               herein specifically prescribed) may, in the absence of bad faith
               on its part, request and conclusively rely upon an Officers'
               Certificate which, upon receipt of such request, shall be

               --------  -------
               (a)(vi) shall be taken to relieve the Property Trustee, upon the
               occurrence of an Event of Default (of which, other than in the
               case of Events of Default under Sections 5.01(a) and 5.01(b) of

               knowledge of as provided in Section 2.7(b) hereof, a Responsible
               Officer of the Property Trustee has actual knowledge), of its
               obligation to exercise the rights and powers vested in it by this

               request, direction, consent, order, bond, debenture, note, other
               evidence of indebtedness or other paper or document, but the
               Property Trustee, in its discretion, may make such further
               inquiry or investigation into such facts or matters as it may see
               fit;

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

               taking any other action hereunder, the Property Trustee (i) may
               request instructions from the Holders which instructions may only
               be given by the Holders of the same proportion in liquidation
               amount of the Securities as would be entitled to direct the
               Property Trustee under the terms of the Securities in respect of
               such remedy, right or action, (ii) may refrain from enforcing
               such remedy or right or taking such other action until such

               action taken, suffered, or omitted to be taken by it in good
               faith, without negligence or willful misconduct, and reasonably
               believed by it to be authorized or within the discretion or
               rights or powers conferred upon it by this Declaration.

               (b)  No provision of this Declaration shall be deemed to impose
any duty or obligation on the Property Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it, in any
jurisdiction in which it shall be illegal, or in which the Property Trustee
shall be unqualified or incompetent in accordance with applicable

                                       24


law, to perform any such act or acts, or to exercise any such right, power, duty
or obligation. No permissive power or authority available to the Property
Trustee shall be construed to be a duty.

SECTION 3.15   Mergers.

an entirety to any Person, except as described in Section 3.15(b) and (c) and
except with respect to the distribution of Debentures to Holders pursuant to
Section 8.1(a)(iii) of this Declaration or Section 3 of Annex I.

          (b)  The Trust may, at the request of the Sponsor, with the consent of

Trustee or the Property Trustee, merge with or into, consolidate, amalgamate, or
be replaced by, or convey, transfer or lease its properties and assets as an
entirety or substantially as an entirety to, a trust organized as such under the
laws of any State; provided that:
                   -------- ----

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

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

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

               (ii)   the Sponsor expressly appoints a trustee of the Successor
          Entity that possesses the same powers and duties as the Property
          Trustee with respect to the Debentures;

               (iii)  the Successor Securities (excluding any securities
          substituted for the Common Securities) are listed, quoted or included
          for trading, or any Successor Securities will be listed, quoted or
          included for trading upon notification of issuance, on any national
          securities exchange or with any other organization on which the
          Capital Securities are then listed, quoted or included;

               (iv)   such merger, consolidation, amalgamation, replacement,
          conveyance, transfer or lease does not cause the Capital Securities
          (including any Successor Securities) or the Debentures to be
          downgraded by any nationally recognized statistical rating
          organization that publishes a rating on the Capital Securities or the
          Debentures;

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

                                       26


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

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

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

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

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

               (viii) the Sponsor or any permitted successor or assignee of the
          Sponsor owns all of the common securities of the Successor Entity and
          guarantees the obligations of the Successor Entity under the Successor
          Securities at least to the extent provided by the Securities
          Guarantees; and

               (ix)   there shall have been furnished to the Property Trustee an
          Officers' Certificate and an Opinion of Counsel, each to the effect
          that all conditions precedent in this Declaration to such transaction
          have been satisfied.

          (c)  Notwithstanding Section 3.15(b), the Trust shall not, except with
the consent of Holders of 100% in aggregate liquidation amount of the
Securities, consolidate, amalgamate, merge with or into, or be replaced by, or
convey, transfer or lease its properties and assets as an entirety or
substantially as an entirety to, any other Person or permit any other Person to
consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, replacement, conveyance, transfer or lease
would cause the Trust or the Successor Entity not to be classified as a grantor
trust for United States federal income tax purposes.

then issued by the Trust, in an amount equal to at least 3% of the total capital
of the Trust, at the same time as the Series A Capital Securities are issued and

SECTION 4.2    Responsibilities of the Sponsor.
               -------------------------------

               In connection with the issue and sale of the Capital Securities,
the Sponsor shall have the exclusive right and responsibility to engage in, or
direct the Administrative Trustees to engage in, the following activities:

               (a)  to prepare the Offering Memorandum, in preliminary and final
form, and to prepare for filing by the Trust with the Commission any
Registration Statement, including any amendments thereto, as contemplated by the
Registration Rights Agreement;

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

               (c)  if deemed necessary or advisable by the Sponsor, to prepare
for filing by the Trust an application to permit the Capital Securities to trade
or be quoted or listed in or on the PORTAL Market, or any other securities
exchange, quotation system or the Nasdaq Stock Market's National Market;

               (d)  to prepare for filing by the Trust with the Commission a

SECTION 4.3    Right to Proceed.
               ----------------

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

                                       28

               -----------------------

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

               The death, resignation, retirement, removal, bankruptcy,

anticipated purposes of the meeting. The presence (whether in person or by
telephone) of an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Declaration, any action of the Administrative
Trustees may be taken at a meeting by vote of a majority of the Administrative
Trustees present (whether in person or by telephone) and eligible to vote with
respect to such matter, provided that, a Quorum is present, or without a meeting
                        -------- ----

of such things and the execution

                                       34

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

               -----------------------------------------------------------

Trustee or any Administrative Trustee that is not a natural person, as the case
may be, may be merged or converted or with which it may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which the
Property Trustee or the Delaware Trustee, as the case may be, shall be a party,
or any Person succeeding to all or substantially all the corporate trust
business of the Property Trustee or the Delaware Trustee, as the case may be,

                                 DISTRIBUTIONS

SECTION 6.1    Distributions.
               -------------

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

                                  ARTICLE VII
                            ISSUANCE OF SECURITIES

SECTION 7.1    General Provisions Regarding Securities.
               ---------------------------------------

               (a)  The Administrative Trustees shall, on behalf of the Trust,
issue one class of capital securities representing undivided preferred
beneficial interests in the assets of the Trust having such terms as are set
forth in Annex I (the "Series A Capital Securities") and one class of common
securities representing undivided common beneficial interests in the assets of
the Trust having such terms as are set forth in Annex I (the "Common
Securities"). The Administrative Trustees shall, on behalf of the Trust, issue
one class of capital securities representing undivided preferred beneficial
interests in the assets of the Trust having such terms as set forth in Annex I
(the "Series B Capital Securities") in exchange for the Series A Capital
Securities accepted for exchange in the Exchange Offer, which Series B Capital
Securities shall

                                       35


not bear the legends required by Section 9.2(i) unless the Holder of such Series
A Capital Securities is either (A) a broker-dealer who purchased such Series A
Capital Securities directly from the Trust for resale pursuant to Rule 144A or
any other available exemption under the Securities Act, (B) a Person
participating in the distribution of the Series A Capital Securities or (C) a
Person who is an Affiliate of the Sponsor or the Trust. The Trust shall issue no
securities or other interests in the assets of the Trust other than the Capital
Securities and the Common Securities.

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

               (c)  Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued and,
subject to the terms of this Declaration, fully paid and nonassessable undivided
beneficial interests in the assets of the Trust and entitled to the benefits of
this Declaration, and the Holders thereof shall be entitled to the benefits of
this Declaration.

               (d)  Every Person, by virtue of having become a Holder or a
Capital Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

SECTION 7.2    Execution and Authentication.
               ----------------------------

               (a)  The Securities shall be signed on behalf of the Trust by an
Administrative Trustee.  In case any Administrative Trustee of the Trust who
shall have signed any of the Securities shall cease to be such Administrative
Trustee before the Securities so signed shall be delivered by the Trust, such
Securities nevertheless may be delivered as though the Person who signed such
Securities had not ceased to be such Administrative Trustee; and any Securities
may be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Administrative Trustees of the Trust,
although at the date of the execution and delivery of this Declaration any such
person was not an Administrative Trustee.

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

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

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

                                       36


number of Capital Securities outstanding at any time shall not exceed the number
set forth in Annex I hereto except as provided in Section 7.6.

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

SECTION 7.3    Form and Dating.
               ---------------

               The Capital Securities shall be evidenced by one or more
certificates substantially in the form of Exhibit A-1, and the Common Securities
shall be evidenced by one or more certificates substantially in the form of
Exhibit A-2. The Property Trustee's certificate of authentication shall be
substantially in the form set forth in Exhibit A-1. Certificates representing
the Securities may be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to an Administrative Trustee, as
evidenced by the execution thereof. The Securities may have letters, "CUSIP" or
other numbers, notations or other marks of identification or designation and
such legends or endorsements required by law, stock exchange rule, agreements to
which the Trust is subject, if any, or usage, provided that, any such notation,
                                              -------- ----
legend or endorsement is in a form acceptable to the Administrative Trustees, as
evidenced by their execution thereof. The Trust at the direction of the Sponsor,
shall furnish any such legend not contained in Exhibit A-1 to the Property
Trustee in writing. Each Capital Security shall be dated the date of its
authentication. The terms and provisions of the Securities set forth in Annex I
and the forms of Securities set forth in Exhibits A-1 and A-2 are part of the
terms of this Declaration and, to the extent applicable, the Property Trustee
and the Sponsor, by their execution and delivery of this Declaration, expressly
agree to such terms and provisions and to be bound thereby.

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

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

                                       37


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

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

               (c)  Definitive Capital Securities. Except as provided in Section
                    -----------------------------
7.9 or 9.2(f)(i), owners of beneficial interests in the Global Capital Security
will not be entitled to receive physical delivery of certificated Capital
Securities ("Definitive Capital Securities"). Purchasers of Securities who are
"accredited investors" (as defined in Rule 501(a)(1), (2), (3) or (7) under the
Securities Act) and who are not QIBs will receive Capital Securities in the form
of individual certificates in definitive, fully registered form without
distribution coupons and with the Restricted Securities Legend set forth in
Exhibit A-1 hereto ("Restricted Definitive Capital Securities"); provided,
                                                                 --------
however, that upon registration of transfer of such Restricted Definitive
- -------
Capital Securities to a QIB, such Restricted Definitive Capital Securities will,
unless the Global Capital Security has previously been exchanged, be exchanged
for an interest in the Global Capital Security pursuant to the provisions of
Section 9.2. Restricted Definitive Capital Securities will bear the Restricted
Securities Legend set forth on Exhibit A-1 unless removed in accordance with
this Section 7.3 or Section 9.2.

SECTION 7.4    Registrar, Paying Agent and Exchange Agent.
               ------------------------------------------

               The Trust shall maintain in Wilmington, Delaware (i) an office or
agency where Capital Securities may be presented for registration of transfer
("Registrar"), (ii) an office or agency where Capital Securities may be
presented for payment ("Paying Agent") and (iii) an office or agency where
Securities may be presented for exchange ("Exchange Agent"). The Registrar shall
keep a register of the Capital Securities and of their transfer. The Trust may
appoint the Registrar, the Paying Agent and the Exchange Agent and may appoint
one or more co-registrars, one or more additional paying agents and one or more
additional Exchange Agents in such other locations as it shall determine. The
term "Registrar" includes any additional registrar, the term "Paying Agent"
includes any additional paying agent and the term "Exchange Agent" includes any
additional Exchange Agent. The Trust may change any Paying Agent,

                                       38


Registrar, co-registrar or Exchange Agent without prior notice to any
Holder.  The Paying Agent shall be permitted to resign as Paying Agent upon 30
days' written notice to the Property Trustee, the Administrative Trustees and
the Sponsor.  The Trust shall notify the Property Trustee of the name and
address of any Agent not a party to this Declaration.  If the Trust fails to
appoint or maintain another entity as Registrar, Paying Agent or Exchange Agent,
the Property Trustee shall act as such.  The Trust or any of its Affiliates may
act as Paying Agent, Registrar, or Exchange Agent.  The Trust shall act as
Paying Agent, Registrar and Exchange Agent for the Common Securities.

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

SECTION 7.5   Paying Agent to Hold Money in Trust.
              -----------------------------------

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

SECTION 7.6   Replacement Securities.
              ----------------------

              If a Holder claims that a Security owned by it has been lost,
destroyed or wrongfully taken or if such Security is mutilated and is
surrendered to the Trust or in the case of the Capital Securities to the
Property Trustee, an Administrative Trustee shall execute and the Property
Trustee shall authenticate and make available for delivery a replacement
Security if the Property Trustee's requirements are met.  An indemnity bond must
be provided by the Holder which, in the judgment of the Property Trustee, is
sufficient to protect the Trustees, the Sponsor, the Trust or any authenticating
agent from any loss which any of them may suffer if a Security is replaced.  The
Trust may charge such Holder for its expenses in replacing a Security.

SECTION 7.7   Outstanding Capital Securities.
              ------------------------------

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

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

                                       39


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

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

SECTION 7.8   Capital Securities in Treasury.
              ------------------------------

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

SECTION 7.9   Temporary Securities.
              --------------------

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

              (b) The Global Capital Security deposited with the Clearing Agency
or with the Property Trustee as custodian for the Clearing Agency pursuant to
Section 7.3 shall be transferred to the beneficial owners thereof in the form of
Definitive Capital Securities only if such transfer complies with Section 9.2
and (i) the Clearing Agency notifies the Sponsor that it is unwilling or unable
to continue as Clearing Agency for such Global Capital Security or if at any
time such Clearing Agency ceases to be a "clearing agency" registered under the
Exchange Act, and, in each case, a clearing agency is not appointed by the
Sponsor within 90 days of receipt of such notice or of becoming aware of such
condition, (ii) a Default or an Event of Default has occurred and is continuing,
or (iii) the Trust at its sole discretion elects to cause the issuance of
Definitive Capital Securities.

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

                                       40


Security shall, except as otherwise provided by Sections 7.3 and 9.1, bear the
Restricted Securities Legend set forth in Exhibit A-l hereto.

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

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

SECTION 7.10   Cancellation.
               ------------

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

SECTION 7.11   CUSIP Numbers.
               -------------

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

                                 ARTICLE VIII

                             DISSOLUTION OF TRUST

SECTION 8.1    Dissolution of Trust.
               --------------------

               (a) The Trust shall automatically dissolve:

                   (i)  upon the bankruptcy of the Sponsor;

                   (ii) upon the filing of a certificate of dissolution or
               liquidation or its equivalent with respect to the Sponsor; or the
               revocation of the Sponsor's

                                       41


               charter and the expiration of 90 days after the date of
               revocation without a reinstatement thereof;

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

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

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

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

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

               (b) As soon as is practicable upon completion of winding up of
the Trust following the occurrence of an event referred to in Section 8.1(a) and
the satisfaction of creditors of the Trust in accordance with applicable law,
the Administrative Trustees shall terminate the Trust by filing a certificate of
cancellation with the Secretary of State of the State of Delaware in accordance
with the Business Trust Act.

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

                                  ARTICLE IX

                             TRANSFER OF INTERESTS

SECTION 9.1    Transfer of Securities.
               ----------------------

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

                                       42


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

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

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

SECTION 9.2    Transfer Procedures and Restrictions.
               ------------------------------------

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

                                       43


direction of an Administrative Trustee on behalf of the Trust, shall
authenticate and deliver Capital Securities that do not bear the legend.

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

       (c) Transfer and Exchange of Definitive Capital Securities.  When
           ------------------------------------------------------
Definitive Capital Securities are presented to the Registrar or co-registrar:

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

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

     provided, however, that the Definitive Capital Securities surrendered for
     --------  -------
     registration of transfer or exchange:

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

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

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

                                       44


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

       (d) Restrictions on Transfer of a Definitive Capital Security for a
           ---------------------------------------------------------------
Beneficial Interest in the Global Capital Security.  A Definitive Capital
- --------------------------------------------------
Security may not be exchanged for a beneficial interest in the Global Capital
Security except upon satisfaction of the requirements set forth below.  Upon
receipt by the Property Trustee of a Definitive Capital Security, duly endorsed
or accompanied by appropriate instruments of transfer, in form satisfactory to
the Property Trustee, together with:

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

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

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

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

       (f) Transfer of a Beneficial Interest in the Global Capital Security for
           --------------------------------------------------------------------
a Definitive Capital Security.
- -----------------------------

           (i) Any Person having a beneficial interest in the Global Capital
       Security may upon request, but only upon 20 days prior notice to the
       Property Trustee, and if accompanied by the information specified below,
       exchange such beneficial interest for a Definitive Capital Security
       representing the same number of Capital Securities. Upon receipt by the
       Property Trustee from the Clearing Agency or its nominee on behalf of any
       Person having a beneficial

                                       45


     interest in the Global Capital Security of written instructions or such
     other form of instructions as is customary for the Clearing Agency or the
     Person designated by the Clearing Agency as having such a beneficial
     interest in a Restricted Capital Security and certification(s) from the
     transferor in a form substantially similar to that attached hereto as the
     form of "Assignment" in Exhibit A-1, which may be submitted by facsimile,
     then the Property Trustee will cause the aggregate number of Capital
     Securities represented by the Global Capital Security to be reduced on its
     books and records and, following such reduction, the Trust will execute and
     the Property Trustee will authenticate and make available for delivery to
     the transferee a Definitive Capital Security.

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

     (g)  Restrictions on Transfer and Exchange of the Global Capital Security.
          --------------------------------------------------------------------
Notwithstanding any other provisions of this Declaration (other than the
provisions set forth in subsection (h) of this Section 9.2), the Global Capital
Security may not be transferred as a whole except by the Clearing Agency to a
nominee of the Clearing Agency or another nominee of the Clearing Agency or by
the Clearing Agency or any such nominee to a successor Clearing Agency or a
nominee of such successor Clearing Agency.

     (h)  Authentication of Definitive Capital Securities.  If at any time:

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

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

          (iii) the Clearing Agency notifies the Sponsor that it is unwilling or
     unable to continue as Clearing Agency for such Global Capital Security or
     if at any time such Clearing Agency ceases to be a "clearing agency"
     registered under the Exchange Act, and, in each case, a clearing agency is
     not appointed by the Sponsor within 90 days of receipt of such notice or of
     becoming aware of such condition,

then an Administrative Trustee on behalf of the Trust will execute, and the
Property Trustee, upon receipt of a written order of the Trust signed by one
Administrative Trustee requesting the authentication and delivery of Definitive
Capital Securities to the Persons designated by the

                                       46


Trust, will authenticate and make available for delivery Definitive Capital
Securities, equal in number to the number of Capital Securities represented by
the Global Capital Security, in exchange for such Global Capital Security.

       (i)        Legend.

       Capital Security Certificate evidencing the Global Capital Security and
       each Definitive Capital Security (and all Capital Securities issued in
       exchange therefor or substitution thereof) shall bear a legend (the
       "Restricted Securities Legend") in substantially the following form:

       without charge, but only upon payment (with such indemnity as the Trust
       or the Sponsor may require) in respect of any tax or other governmental
       charge that may be imposed in relation to it.

            (iii)  The Registrar or co-registrar shall not be required to
       register the transfer of or exchange of (a) Capital Securities during a
       period beginning at the opening of business 15 days before the day of

       records of the Clearing Agency or its nominee or of any Participant
       thereof, with respect to any ownership interest in the Capital Securities
       or with respect to the delivery to any Participant, beneficial owner or
       other Person (other than the Clearing Agency) of any notice (including

               the Clearing Agency or its nominee in the case of the Global
               Capital Security). The rights of Capital Security Beneficial
               Owners shall be exercised only through the Clearing Agency
               subject to the applicable rules and procedures of the Clearing
               Agency. The Property Trustee may conclusively rely and shall be
               fully protected in relying upon information furnished by the
               Clearing Agency or any agent thereof with respect to its
               Participants and any Capital Security Beneficial Owners.

               obligation or duty to monitor, determine or inquire as to
               compliance with any restrictions on transfer imposed under this
               Declaration or under applicable law with respect to any transfer
               of any interest in any Capital Security (including any transfers
               between or among Clearing Agency Participants or Capital Security
               Beneficial Owners) other than to require delivery of such
               certificates and other documentation or evidence as are expressly
               required by, and to do so if and when expressly required by, the
               terms of this Declaration, and to examine the same to determine
               substantial compliance as to form with the express requirements

liquidation amount of less than $100,000 shall be deemed to be voided and of no
legal effect whatsoever. Any such purported transferee shall be deemed not to be
a Holder of such Series A Capital Securities or Series B Capital Securities for
any purpose, including, but not limited to, the receipt of Distributions on such
Capital Securities, and such purported transferee shall be deemed to have no
interest whatsoever in such Capital Securities.

SECTION 9.3    Deemed Security Holders.
               -----------------------

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

SECTION 9.4    Book-Entry Interests.
               --------------------

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

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

                                       53


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

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

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

SECTION 9.5    Notices to Clearing Agency.
               --------------------------

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

SECTION 9.6    Appointment of Successor Clearing Agency.
               ----------------------------------------

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

                          LIMITATION OF LIABILITY OF
                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1   Liability.
               ---------

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

                                       54


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

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

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

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

SECTION 10.2   Exculpation.
               -----------

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

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

SECTION 10.3   Fiduciary Duty.
               --------------

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

               (b)  Unless otherwise expressly provided herein:

                                       55


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

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

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

               (c)  Whenever in this Declaration an Indemnified Person is
permitted or required to make a decision:

                    (i)  in its "discretion" or under a grant of similar
               authority, the Indemnified Person shall be entitled to consider
               such interests and factors as it desires, including its own
               interests, and shall have no duty or obligation to give any
               consideration to any interest of or factors affecting the Trust
               or any other Person; or

                    (ii) in its "good faith" or under another express standard,
               the Indemnified Person shall act under such express standard and
               shall not be subject to any other or different standard imposed
               by this Declaration or by applicable law.

SECTION 10.4   Indemnification.
               ---------------

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

                                       56


respect to any criminal action or proceeding, had reasonable cause to believe
that his conduct was unlawful.

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

                    (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
               or she shall be indemnified, to the full extent permitted by law,
               against expenses (including attorneys' fees) actually and
               reasonably incurred by him or her in connection therewith.

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

                    (v)    Expenses (including attorneys' fees and expenses)
               incurred by a Company Indemnified Person in defending a civil,
               criminal, administrative or investigative action, suit or
               proceeding referred to in paragraphs (i) and (ii) of this Section
               10.4(a) shall be paid by the Sponsor in advance of the final

                                       57


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

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

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

                                       58


               employee of such constituent entity, or is or was serving at the
               request of such constituent entity as a director, trustee,
               officer, employee or agent of another entity, shall stand in the
               same position under the provisions of this Section 10.4(a) with
               respect to the resulting or surviving entity as he or she would
               have with respect to such constituent entity if its separate
               existence had continued.

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

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

               (c)  The Sponsor agrees to pay the Property Trustee and the
Delaware Trustee, from time to time, such compensation for all services rendered
by the Property Trustee and the Delaware Trustee hereunder as may be mutually
agreed upon in writing by the Sponsor and the Property Trustee or the Delaware
Trustee, as the case may be, and, except as otherwise expressly provided herein,
to reimburse the Property Trustee and the Delaware Trustee upon its or their
request for all reasonable expenses (including legal fees and expenses),
disbursements and advances incurred or made by the Property Trustee or the
Delaware Trustee, as the case may be, in accordance with the provisions of this
Declaration, except any such expense, disbursement or advance as may be
attributable to its or their negligence (or gross negligence on the part of the
Delaware Trustee) or bad faith.

SECTION 10.5   Outside Businesses.
               ------------------

               Any Covered Person, the Sponsor, the Delaware Trustee and the
Property Trustee (subject to Section 5.3(c)) may engage in or possess an
interest in other business

                                       59


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

SECTION 11.1   Fiscal Year.
               -----------

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

SECTION 11.2   Certain Accounting Matters.
               --------------------------

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

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

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

                                       60


annual income tax returns required to be filed by the Administrative Trustees on

SECTION 11.3   Banking.
               -------

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

SECTION 11.4   Withholding.
               -----------

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

direction shall be given by delivering to the Administrative Trustees one or
more notices in writing stating that the signing Holders wish to call a meeting
and indicating the general or specific purpose for which the meeting is to be

Security Certificates held by the Holders exercising the right to call a meeting
and only those Securities specified shall

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

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

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

               terms of the Securities, the Trust Indenture Act or the listing
               rules of any stock exchange on which the Capital Securities are
               then listed or trading, otherwise provides, the Administrative
               Trustees, in their sole discretion, shall establish all other
               provisions relating to meetings of Holders, including notice of
               the time, place or purpose of any meeting at which any matter is
               to be voted on by any

                                       64


          Holders, waiver of any such notice, action by consent without a
          meeting, the establishment of a record date, quorum requirements,

                                    ANNEX I

                                   TERMS OF
                  10.75% CAPITAL SECURITIES, SERIES A/SERIES B
                            10.75% COMMON SECURITIES

          Pursuant to Section 7.1 of the Amended and Restated Declaration, dated
as of May 19, 2000 (as amended from time to time, the "Declaration"), the
designation, rights, privileges, restrictions, preferences and other terms and
provisions of the Securities are set out below (each capitalized term used but
not defined herein has the meaning set forth in the Declaration, the Indenture
or, if not defined in such Declaration or Indenture, as defined in the Offering
Memorandum referred to below in Section 2(c) of this Annex I):

     1.   Designation and Number.
          ----------------------

     (a)  Capital Securities.  10.75% Series A Capital Securities of the Trust
          ------------------
and 10.75% Series B Capital Securities of the Trust, each series with an
aggregate liquidation amount with respect to the assets of the Trust of Forty-
one Million Dollars ($41,000,000) and with a liquidation amount with respect to
the assets of the Trust of One Thousand Dollars ($1,000) (the "Liquidation
Amount") per security, are hereby designated for the purposes of identification
only as "10.75% Capital Securities, Series A" and "10.75% Capital Securities,
Series B," respectively (collectively, the "Capital Securities").  The
certificates evidencing the Capital Securities shall be substantially in the
form of Exhibit A-1 to the Declaration, with such changes and additions thereto
or deletions therefrom as may be required by ordinary usage, custom or practice
or to conform to the rules of any exchange or quotation system on or in which
the Capital Securities are listed, traded or quoted.

     (b)  Common Securities.  1,268 Common Securities of the Trust with an
          -----------------
aggregate liquidation amount with respect to the assets of the Trust of One
Million Two Hundred Sixty-eight Thousand Dollars ($1,268,000) and a liquidation
amount with respect to the assets of the Trust of $1,000 per security, are
hereby designated for the purposes of identification only as "10.75% Common
Securities" (the "Common Securities").  The certificates evidencing the Common
Securities shall be substantially in the form of Exhibit A-2 to the Declaration,
with such changes and additions thereto or deletions therefrom as may be
required by ordinary usage, custom or practice.

     2.   Distributions.
          -------------

     (a)  Distributions on each Security will be payable at a fixed rate per
annum of 10.75%  (the "Coupon Rate") of the liquidation amount of $1000 per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Property Trustee.  Distributions in arrears for more than one semi-
annual period will bear additional Distributions thereon compounded semi-
annually at the Coupon Rate (to the extent permitted by applicable law).
Pursuant to the Registration Rights Agreement and the Liquidated Damages
Agreement, in certain limited circumstances the Debenture Issuer will be
required to pay Liquidated Damages (as defined in the Registration Rights
Agreement and the Liquidated Damages Agreement) with respect to the Debentures.
The term "Distributions" as used herein, includes distributions of any and all
such interest and Liquidated Damages, if any, payable unless otherwise stated.
A

                                      I-1


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

     (b)  Distributions on the Securities will be cumulative, will accumulate
from the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from May 19, 2000 and will be payable semi-
annually in arrears on June 1st and December 1st of each year, commencing
December 1, 2000 (each, a "Distribution Date"), except as otherwise described
below.  Distributions will be computed on the basis a 360-day year of twelve 30-
day months.  As long as no Event of Default has occurred and is continuing under
the Indenture, the Debenture Issuer has the right under the Indenture to defer
payments of interest by extending the interest payment period at any time and
from time to time on the Debentures for a period not exceeding ten consecutive
semi-annual periods, including the first such semi-annual period during such
period (each an "Extension Period"), during which Extension Period no interest
shall be due and payable on the Debentures, provided that no Extension Period
                                            -------- ----
shall end on a date other than an Interest Payment Date for the Debentures or
extend beyond the Maturity Date of the Debentures.  As a consequence of such
deferral, Distributions (other than Liquidated Damages, if any) will also be
deferred.  Notwithstanding such deferral, Distributions will continue to
accumulate with additional Distributions thereon (to the extent permitted by
applicable law but not at a rate greater than the rate at which interest is then
accruing on the Debentures) at the Coupon Rate compounded semi-annually during
any such Extension Period.  Prior to the termination of any such Extension
Period, the Debenture Issuer may further defer payments of interest by further
extending such Extension Period, provided that such extension does not cause
                                 -------- ----
such Extension Period, together with all such previous and further extensions
within such Extension Period, to exceed ten consecutive semi-annual periods,
including the first semi-annual period during such Extension Period, end on a
date other than an Interest Payment Date for the Debentures or extend beyond the
Maturity Date of the Debentures.  Upon the termination of any Extension Period
and the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

     (c)  Distributions on the Securities will be payable to the Holders thereof
as they appear on the books and records of the Trust on the close of business on
the 15/th/ day of the month immediately preceding the month in which the
relevant Distribution Date occurs, which Distribution Dates correspond to the
Interest Payment Dates for the Debentures.  Subject to any applicable laws and
regulations and the provisions of the Declaration, each such payment with
respect to the Capital Securities will be made as described under the heading
"Description of Capital Securities--Form, Denomination, Book-Entry Procedures
and Transfer" in the Offering Memorandum dated May 16, 2000 of the Debenture
Issuer and the Trust relating to the Securities and the Debentures.  The
relevant record dates for the Common Securities shall be the same as the record
dates for the Capital Securities.  Distributions payable on any Securities that
are not punctually paid on any Distribution Date, as a result of the Debenture
Issuer having failed to make a payment under the Debentures, will cease to be
payable to the Holder on the relevant record date, and such defaulted
Distribution will instead be payable to the Person in whose name such Securities
are registered on the special record date or other specified date 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 Distributions
payable on such date will be made on the next succeeding day that is a Business
Day (and without any interest or other payment in respect of any such delay)
with the same force and effect as if made on such date.

                                      I-2


     (d)  In the event that there is any money or other property held by or for
the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders.

     3.   Liquidation Distribution Upon Dissolution.
          -----------------------------------------

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

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

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

     4.   Redemption and Distribution.
          ---------------------------

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

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

                                      I-3


          (ii) The Debenture Issuer shall have the right (subject to the
conditions in the Indenture) to elect to prepay the Debentures, in whole or in
part, at any time on or after June 1, 2010 (the "Initial Optional Redemption
Date"), and, simultaneous with such prepayment, to cause a Like Amount of the
Securities to be redeemed by the Trust at the Optional Redemption Price on a Pro
Rata basis.  "Optional Redemption Price" shall mean an amount equal to 100% of
the Liquidation Amount of the Securities to be redeemed plus, accumulated and
unpaid Distributions thereon, if any, to the date of such redemption:

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

          "Investment Company Event" shall mean the receipt by the Debenture
Issuer and the Trust of an opinion of independent securities counsel experienced
in such matters to the effect that as a result of (a) any amendment to, or
change (including any announced prospective change) in, the laws or any
regulations thereunder of the United States or any rules, guidelines or policies
of any applicable regulatory authority for the Debenture Issuer or (b) any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
which pronouncement or decision is announced on or after the date of original
issuance of the Securities, the Trust is, or within 90 days of the date of such
opinion will be, considered an Investment Company that is required to be
registered under the Investment Company Act.

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

          "Special Event Redemption Price" shall mean, with respect to any
redemption of the Securities following a Special Event, an amount in cash equal
to 100% of the principal amount of the Securities plus any accrued and unpaid
interest thereon (including Compounded Interest and Additional Sums, if any) to
the date of such redemption.

          A "Tax Event" shall occur upon receipt by the Debenture Issuer and the
Trust of an opinion of independent tax counsel experienced in such matters to
the effect that, as a result of (a) any amendment to, or change (including any
announced prospective change) in, the laws or

                                      I-4


any regulations thereunder of the United States or any political subdivision or
taxing authority thereof or therein, or (b) any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or which pronouncement or
decision is announced on or after the date of original issuance of the
Securities, there is more than an insubstantial risk that (i) the Trust is, or
will be within 90 days of the date of such opinion, subject to United States
federal income tax with respect to income received or accrued on the Debentures,
(ii) the interest payable by the Debenture Issuer on the Debentures is not, or
within 90 days of the date of such opinion will not be, deductible by the
Debenture Issuer, in whole or in part, for federal income tax purposes, or (iii)
the Trust is, or will be within 90 days of the date of such opinion, subject to
more than a de minimis amount of other taxes, duties or other governmental
charges.

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

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

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

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

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

                                      I-5


     Holder shall affect the validity of the redemption or exchange proceedings
     with respect to any other Holder.

          (ii)  In the event that fewer than all the outstanding Securities are
     to be redeemed, the particular Securities to be redeemed shall be selected
     on a Pro Rata basis (based upon Liquidation Amounts) not more than 60 nor
     less than 30 days prior to the date fixed for redemption from the
     outstanding Securities not previously called for redemption; provided,
                                                                  --------
     however, that with respect to Holders that would be required to hold less
     -------
     than 100 but more than zero Securities as a result of such redemption, the
     Trust shall redeem Securities of each such Holder so that after such
     redemption such Holder shall hold either 100 Securities or such Holder no
     longer holds any Securities, and shall use such method (including, without
     limitation, by lot) as the Trust shall deem fair and appropriate; provided,
                                                                       --------
     further, that any such redemption may be made on the basis of the aggregate
     -------
     Liquidation Amount of Securities held by each Holder thereof and may be
     made by making such adjustments as the Trust deems fair and appropriate in
     order that fractional Securities shall not thereafter remain outstanding.
     With respect to Capital Securities registered in the name of and held of
     record by the Clearing Agency or its nominee (or any successor Clearing
     Agency or its nominee) or any nominee, the distribution of the proceeds of
     such redemption will be made to the Clearing Agency and disbursed by such
     Clearing Agency in accordance with the procedures applied by such agency or
     nominee.

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

                                      I-6


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

     Neither the Administrative Trustees nor the Trust shall be required to
register or cause to be registered the transfer of (i) any Securities beginning
at the opening of business 15 days before the day of mailing of a notice of
redemption or any notice of selection of Securities for redemption or (ii) any
Securities selected for redemption, except the unredeemed portion of any
Security being redeemed.  If any date fixed for redemption of Securities is not
a Business Day, then payment of the Redemption Price payable on such date will
be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay).  If payment of the
Redemption Price with respect to any Securities is improperly withheld or
refused and not paid either by the Property Trustee or by the Sponsor as
guarantor pursuant to the relevant Securities Guarantee, Distributions on such
Securities will continue to accumulate from the original redemption date to the
actual date of payment, in which case the actual payment date will be considered
the date fixed for redemption for purposes of calculating the Redemption Price.

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

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

     5.   Voting Rights - Capital Securities.
          ----------------------------------

     (a)  Except as provided under Sections 5(b), 6(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Capital Securities will
have no voting rights.

     (b)  So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee or executing any
trust or power conferred on such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.07 of
the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures or (iv) consent
to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in Liquidation Amount
of all outstanding Capital Securities; provided, however, that where a consent
                                       --------  -------
under the Indenture would require the consent of each holder of Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior approval of each Holder of the Capital Securities.  The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of the Capital Securities except by subsequent vote of such Holders.  The
Property

                                      I-7


Trustee shall notify each Holder of Capital Securities of any notice of
default with respect to the Debentures.  In addition to obtaining the foregoing
approvals of such Holders of the Capital Securities, prior to taking any of the
foregoing actions, the Trustees shall obtain an opinion of counsel experienced
in such matters to the effect that the Trust will continue to be classified as a
grantor trust for United States federal income tax purposes after taking any
such action into account.

          If an Event of Default under the Declaration has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay principal of or interest on the Debentures on the due date (or, in the
case of redemption, on the redemption date), then a Holder of Capital Securities
may institute a proceeding directly against the Debenture Issuer for enforcement
of payment to such Holder of the principal of or interest on a Like Amount of
Debentures (a "Direct Action") on or after the respective due date specified in
the Debentures.  In connection with such Direct Action, the Common Securities
Holder will be subrogated to the rights of such Holder of Capital Securities to
the extent of any payment made by the Debenture Issuer to such Holder of Capital
Securities in such Direct Action.  Except as provided in the second preceding
sentence, or except as set forth in the first sentence of Section 3.8(e) of the
Declaration, the Holders of Capital Securities will not be able to exercise
directly any other remedy available to the holders of the Debentures.

          Any approval or direction of Holders of Capital Securities may be
given at a separate meeting of Holders of Capital Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Property Trustee will cause a notice of any
meeting at which Holders of Capital Securities are entitled to vote to be mailed
to each Holder of record of Capital Securities.  Each such notice will include a
statement setting forth (i) the date of such meeting or the date by which such
action is to be taken, (ii) a description of any resolution proposed for
adoption at such meeting on which such Holders are entitled to vote or of such
matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consent.

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

          Notwithstanding that Holders of Capital Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Capital Securities that are owned by the Sponsor or any Affiliate of the Sponsor
shall not be entitled to vote or consent and shall, for purposes of such vote or
consent, be treated as if they were not outstanding.

     6.   Voting Rights - Common Securities.
          ---------------------------------

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

     (b)  Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by the Holder of the Common
Securities.  If a Debenture Event of Default has occurred and is continuing, the
Property Trustee and the Delaware Trustee may be removed at such time by the
Holders of a Majority in Liquidation Amount of the

                                      I-8


outstanding Capital Securities. In no event will the Holders of the Capital
Securities have the right to vote to appoint, remove or replace the
Administrative Trustees, which voting rights are vested exclusively in the
Sponsor as the Holder of the Common Securities. No resignation or removal of a
Trustee and no appointment of a successor trustee shall be effective until the
acceptance of appointment by the successor trustee in accordance with the
provisions of the Declaration.

     (c)  So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on such Debenture Trustee with respect to the
Debentures, (ii) waive any past default that is waivable under Section 5.7 of
the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures or (iv) consent
to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in Liquidation Amount
of all outstanding Common Securities; provided, however, that where a consent
                                      --------  -------
under the Indenture would require the consent of each holder of Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior approval of each Holder of the Common Securities.  The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of the Common Securities except by subsequent vote of such Holders.  The
Property Trustee shall notify each Holder of Common Securities of any notice of
default with respect to the Debentures.  In addition to obtaining the foregoing
approvals of such Holders of the Common Securities, prior to taking any of the
foregoing actions, the Trustees shall obtain an opinion of counsel experienced
in such matters to the effect that the Trust will continue to be classified as a
grantor trust for United States federal income tax purposes after taking any
such action into account.

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

          Any approval or direction of Holders of Common Securities may be given
at a separate meeting of Holders of Common Securities convened for such purpose,
at a meeting of all of the Holders of Securities in the Trust or pursuant to
written consent.  The Administrative Trustees will cause a notice of any meeting
at which Holders of Common Securities are entitled to vote, or of any matter
upon which action by written consent of such Holders is to be taken, to be
mailed to each Holder of record of Common Securities.  Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such

                                      I-9


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

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

     7.   Amendments to Declaration.
          -------------------------

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

     8.   Pro Rata.
          --------

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

          The Capital Securities rank pari passu with the Common Securities and
                                      ---- -----
payment thereon shall be made Pro Rata with the Common Securities, except that,
if an Event of Default under the Declaration occurs and is continuing, no
payments in respect of Distributions on, or payments upon liquidation,
redemption or otherwise with respect to, the Common Securities shall be made

                              WILMINGTON TRUST COMPANY,
                              not in its individual capacity but solely
                              as Property Trustee

                              By:______________________________________
                                 Authorized Signatory

                         [FORM OF REVERSE OF SECURITY]


          Distributions on each Capital Security will be payable at a fixed rate
per annum of 10.75% (the "Coupon Rate") of the liquidation amount of $1,000 per
Capital Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee.  Distributions in arrears for more than one
semi-annual period will bear interest thereon compounded semi-annually at the
Coupon Rate (to the extent permitted by applicable law).  Pursuant to the
Registration Rights Agreement and the Liquidated Damages Agreement, in certain
limited circumstances the Debenture Issuer will be required to pay Liquidated
Damages (as defined in the Registration Rights Agreement and the Liquidated
Damages Agreement) with respect to the Debentures.  The term "Distributions," as
used herein, includes such cash distributions and any and all such interest and
Liquidated Damages, if any, payable unless otherwise stated.  A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Property Trustee and to the extent the Property Trustee has funds
legally available therefor.

          Distributions on the Capital Securities will be cumulative, will
accumulate from the most recent date to which Distributions have been paid or,
if no Distributions have been paid, from May 19, 2000 and will be payable semi-
annually in arrears, on June 1st and December 1st of each year, commencing
December 1, 2000, except as otherwise described below.  Distributions will be
computed on the basis of a 360-day year of twelve 30-day months.  As long as no
Event of Default has occurred and is continuing under the Indenture, the
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period at any time and from time to time on
the Debentures for a period not exceeding ten consecutive semi-annual calendar
periods, including the first such semi-annual period during such extension
period (each an "Extension Period"), provided that no Extension Period shall end
                                     -------- ----
on a date other than an Interest Payment Date for the Debentures or extend
beyond the Maturity Date of the Debentures.  As a consequence of such deferral,
Distributions (other than Liquidated Damages, if any) will also be deferred.
Notwithstanding such deferral, semi-annual Distributions will continue to
accumulate with interest thereon (to the extent permitted by applicable law, but
not at a rate exceeding the rate of interest then accruing on the Debentures) at
the Coupon Rate compounded semi-annually during any such Extension Period.
Prior to the termination of any Extension Period, the Debenture Issuer may
further defer payments of interest by further extending such Extension Period;
provided that such Extension Period, together with all such previous and further
- -------- ----

     (2)  [_]   transferred pursuant to and in compliance with Rule 144A under
                the Securities Act of 1933, as amended; or

     (3)  [_]   transferred to an institutional "accredited investor" within the
                meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501
                under the Securities Act of 1933 that is acquiring the Capital
                Securities for its own account, or for the account of such an
                institutional "accredited investor," for investment purposes and

                amended; or

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

Unless one of the boxes is checked, the Registrar will refuse to register any of
the Capital Securities evidenced by this Certificate in the name of any Person
other than the Holder hereof; provided, however, that if box (3) or (4) is
                              --------  -------

                                                   --------  -------
if box (2) is checked, by acceptance of this Certificate, the transferee shall
be deemed to have certified that it is a "qualified institutional buyer" (as
defined in Rule 144A) ("QIB") acquiring the Capital Securities for its own
account or for the account of another QIB over which it exercises sole
investment discretion and that it is aware that the Holder is relying upon the
exemption from registration afforded by Rule 144A in respect of the Holder's
transfer of Capital Securities to it or (ii) if box (3) is checked, the
transferee must also provide to the Registrar a Transferee Letter of
Representation in the form attached to the Offering Memorandum of the Trust
dated May 16, 2000; provided, further, that after the date that a registration
                    --------  -------
statement has been filed and so long as such Registration Statement continues to
be effective, only then may the Registrar permit transfers for which box (5) has
been checked.

This Certificate is not transferable except in compliance with Section 9.1(c) of
                                the Declaration.

                    Certificate Evidencing Common Securities

                                       of

                                 GBB Capital IV

                            10.75% Common Securities
                (liquidation amount $1,000 per Common Security)

          GBB Capital IV, a statutory business trust created under the laws of
the State of Delaware (the "Trust"), hereby certifies that Greater Bay Bancorp
(the "Holder") is the registered owner of [____] common securities of the Trust
representing undivided beneficial interests in the assets of the Trust
designated the 10.75% Common Securities (liquidation amount $1,000 per Common
Security) (the "Common Securities").  Subject to the terms of Section 9.1(c) of
the Declaration (as defined below), the Common Securities are not transferable.
The designation, rights, privileges, restrictions, preferences and other terms
and provisions of the Common Securities represented hereby are issued and shall
in all respects be subject to the provisions of the Amended and Restated
Declaration of the Trust dated as of May 19, 2000, as the same may be amended
from time to time (the "Declaration"), including the designation of the terms of
the Common Securities as set forth in Annex I to the Declaration.  Capitalized

Declaration.  The Sponsor will provide a copy of the Declaration, the Common
Securities Guarantee and the Indenture (including any supplemental indenture) to

          Upon receipt of this Certificate, the Holder is bound by the
Declaration and is entitled to the benefits thereunder and to the benefits of
the Common Securities Guarantee to the extent provided therein.

          By acceptance hereof, the Holder agrees to treat, for United States
federal income tax purposes, the Debentures as indebtedness and the Common
Securities as evidence of indirect beneficial ownership in the Debentures.

          IN WITNESS WHEREOF, the Trust has executed this certificate this _____
day of ____________, _____.

                              GBB CAPITAL IV

                              By:______________________________
                                 Steven C. Smith
                                 Administrative Trustee

                                      13


                         [FORM OF REVERSE OF SECURITY]

     Distributions on each Common Security will be payable at a rate of 10.75%
per annum (the "Coupon Rate") of the liquidation amount of $1000 per Common
Security, such rate being the rate of interest payable on the Debentures to be
held by the Property Trustee.  Distributions in arrears for more than one semi-
annual period will bear interest thereon compounded semi-annually at the Coupon
Rate (to the extent permitted by applicable law).  Pursuant to the Registration
Rights Agreement, in certain limited circumstances the Debenture Issuer will be
required to pay Liquidated Damages (as defined in the Registration Rights
Agreement) with respect to the Debentures.  The term "Distributions", as used
herein, includes such cash distributions and any and all such interest and
Liquidated Damages, if any, payable unless otherwise stated.  A Distribution is
payable only to the extent that payments are made in respect of the Debentures
held by the Property Trustee and to the extent the Property Trustee has funds
legally available therefor.

     Distributions on the Common Securities will be cumulative, will accrue from
the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from May 19, 2000 and will be payable semi-
annually in arrears, on June 1st and December 1st of each year, commencing
December 1, 2000, except as otherwise described below. Distributions will be
computed on the basis of a 360-day year of twelve 30-day months. As long as no
Event of Default has occurred and is continuing under the Indenture, the
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period at any time and from time to time on
the Debentures for a period not exceeding ten consecutive calendar semi-annual
periods, including the first such semi-annual period during such extension
period (each an "Extension Period"), provided that no Extension Period shall end
                                     -------- ----
on a date other than an Interest Payment Date for the Debentures or extend
beyond the Maturity Date of the Debentures. As a consequence of such deferral,
Distributions will also be deferred. Notwithstanding such deferral, semi-annual
Distributions will continue to accumulate with interest thereon (to the extent
permitted by applicable law, but not at a rate exceeding the rate of interest
then accruing on the Debentures) at the Coupon Rate compounded semi-annually
during any such Extension Period. Prior to the termination of any Extension
Period, the Debenture Issuer may further defer payments of interest by further
extending such Extension Period; provided that such Extension Period, together
                                 -------- ----
with all such previous and further extensions within such Extension Period, may
not (i) exceed to ten consecutive semi-annual periods, including the first semi-
annual period during such Extension Period, (ii) end on a date other than an
Interest Payment Date for the Debentures or (iii) extend beyond the Maturity
Date of the Debentures.  Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the record date
immediately preceding the end of the Extension Period.  Upon the termination of
any Extension Period and the payment of all amounts then due, the Debenture
Issuer may commence a new Extension Period, subject to the above requirements.

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

                                      14


redemption of the Debentures, cause a Like Amount of the Securities to be
redeemed by the Trust.

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

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