     Section 2.6  Events of Default; Waiver.
                  ------------------------- 

     (a)  The Holders of a Majority in liquidation amount of Preferred
Securities may, by vote, on behalf of the Holders of all of the Preferred
Securities, waive any past Event of Default in respect of the Preferred
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

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

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

     The foregoing provisions of this Section 2.6(a) 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.  Upon such waiver, any such
default shall cease to exist, and any Event of Default with respect to the
Preferred 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 Preferred
Securities or impair any right consequent thereon.  Any waiver by the Holders of
the Preferred Securities of an Event of Default with respect to the Preferred
Securities shall also be deemed to constitute a waiver by the Holders of the
Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holders of the Common Securities.

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

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

          (ii) requires the consent or vote of a Super Majority to be waived,
     except where the Holders of the Common Securities are deemed to have waived
     such Event of Default under this Declaration as provided below in the
     proviso to this Section 2.6(b), the Event of Default under this Declaration
     may only be waived by the vote of the Holders of 

                                       8

 
     at least the proportion in liquidation amount of the Common Securities
     which the relevant Super Majority represents of the aggregate principal
     amount of the Subordinated Notes 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 its consequences until all Events of Default with respect to the
Preferred 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 Preferred Securities and only the Holders of the Preferred Securities will
have the right to direct the Property Trustee in accordance with the terms of
the Securities; and provided, further, that any waiver by the Holders of the
Preferred Securities of an Event of Default with respect to the Preferred
Securities shall also be deemed to constitute a waiver by the Holders of the
Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holder of the Common Securities. The foregoing provisions of this
Section 2.6(b) shall be in lieu of (S)316(a)(1)(A) and (S)316(a)(1)(B) of the
Trust Indenture Act and such (S)316(a)(1)(A) and (S)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 any Event of Default under the Indenture by the Property
Trustee at the direction of the Holders of the Preferred Securities constitutes
a waiver of the corresponding Event of Default with respect to the Preferred
Securities under this Declaration.  Any waiver of an Event of Default under the
Indenture by the Property Trustee at the direction of the Holders of the
Preferred Securities shall also be deemed to constitute a waiver by the Holders
of the Common Securities of the corresponding Event of Default under this
Declaration with respect to the Common Securities for all purposes of this
Declaration without further act, vote or consent of the Holders of the Common
Securities. 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.

     Section 2.7  Event of Default; Notice.
                  ------------------------ 

     (a)  The Property Trustee shall, within 90 days after the occurrence of an
Event of Default with respect to the Securities known to the Property Trustee,
transmit by mail, first class postage prepaid, to the Holders of the Securities,
notices of all such defaults unless such defaults have been cured before the
giving of such notice (the term "defaults" for the purposes of this Section
2.7(a) being hereby defined to be an Event of Default as defined in the
Indenture, not including any periods of grace provided for therein and
irrespective of the giving of any notice provided therein); provided, that,
except for a default in the payment of principal of (or premium, if any) or
interest on any of the Subordinated Notes or in the payment of any sinking fund

                                       9

 
installment established for the Subordinated Notes, the Property Trustee shall
be protected in withholding such notice if and so long as the board of
directors, the executive committee, or a trust committee of directors and/or
Responsible Officers, of the Property Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders of the Securities.

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

          (i)  a default under Sections 501(1) and 501(2) of the Indenture; or

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

     Section 3.1  Name.
                  ---- 

     The Trust is named "Oxy Capital Trust I", as such name may be modified from
time to time by the Regular Trustees following written notice to the Holders of
Securities.  The Trust's activities may be conducted under the name of the Trust
or any other name deemed advisable by the Regular Trustees.

     Section 3.2  Office.
                  ------

     The exclusive purposes and functions of the Trust are (a) to issue and sell
Securities and use the proceeds from such sale to acquire the Subordinated
Notes, and (b) except as otherwise limited herein, to engage in only those other
activities necessary, or incidental thereto.  The Trust shall not borrow money,
issue debt or reinvest proceeds derived from investments, pledge any of its
assets, or otherwise undertake (or permit to be undertaken) any activity that
would cause the Trust not to be classified for United States federal income tax
purposes as a grantor trust.  It is the intention of all of the parties hereto
that the Trust created hereunder constitutes a "grantor trust" for United States
federal income tax purposes under the Code, and all parties hereto, and the
Holders of the Preferred Securities by the purchase of the Preferred Securities,
agree to treat the Trust with such characterization.  The provisions of this
Agreement shall be interpreted consistently with such characterization.  Unless
otherwise required by law, by the acceptance of this Trust, neither the
Trustees, the Sponsor nor the Holders of the Preferred Securities or 

                                      10

 
Common Securities will take any position which is contrary to the classification
of the Trust as a grantor trust for United States federal income tax purposes.

     (a)  Subject to the limitations provided in this Declaration and to the
specific duties of the Property Trustee, the Regular Trustees shall have
exclusive and complete authority to carry out the purposes of the Trust.  An
action taken by the Regular Trustees in accordance with their powers shall
constitute the act of and serve to bind the Trust and an action taken by the
Property Trustee on behalf of the Trust in accordance with its powers shall
constitute the act of and serve to bind the Trust.  In dealing with the Trustees
acting on behalf of the Trust, no Person shall be required to inquire into the
authority of the Trustees to bind the Trust.  Persons dealing with the Trust are
entitled to rely conclusively on the power and authority of the Trustees as set
forth in this Declaration.

     (b)  Except as expressly set forth in this Declaration and except if a
meeting of the Regular Trustees is called with respect to any matter over which
the Regular Trustees have power to act, any power of the Regular Trustees may be
exercised by, or with the consent of, any one such Regular Trustee.

     (c)  Unless otherwise determined by the Regular Trustees, and except as
otherwise required by the Business Trust Act or applicable law, any Regular
Trustee is authorized to execute on behalf of the Trust any documents which the
Regular Trustees have the power and authority to cause the Trust to execute
pursuant to Section 3.6, provided that the registration statement referred to in
Section 3.6, including any amendments thereto, shall, subject to Section 3.4(d),
be signed by at least two of the Regular Trustees.

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

     Section 3.5  Title to Property of the Trust.
                  ------------------------------

     Section 3.7  Prohibition of Actions by the Trust and the Trustees.
                  ---------------------------------------------------- 

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

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

          (ii)   acquire any assets other than the Subordinated Notes and any
     cash proceeds received with respect thereto;

          (iii)  possess Trust property for other than a Trust purpose;

          (iv)   make any loans or incur any indebtedness other than loans

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

     to the Subordinated Notes, (B) waive any past default that is waivable
     under Section 513 of the Indenture, (C) exercise any right to rescind or

     termination of the Indenture or the Subordinated Notes, where such consent
     shall be required, unless the Trust shall have received an opinion of
     counsel to the effect that such modification will not cause more than an
     insubstantial risk that for United States federal income tax purposes the
     Trust will not be classified as a grantor trust.

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

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

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

                                      15

 
     (c)  The Property Trustee shall:

          (i)    establish and maintain a segregated noninterest bearing bank
     account (the "Property Trustee Account") in the name of and under the
     exclusive control of the Property Trustee on behalf of the Trust and the
     Holders of the Securities and, upon the receipt of payments of funds made
     in respect of the Subordinated Notes held by the Property Trustee, deposit
     such funds into the Property Trustee Account and make payments to the
     Holders of the Preferred Securities and the Common Securities 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.  The Property Trustee Account shall be an
     account which is maintained with a banking institution the rating on whose
     long term unsecured indebtedness is at least equal to the rating assigned
     to the Preferred Securities by a "nationally recognized statistical rating
     organization", as that term is defined for purposes of Rule 436(g)(2) under
     the Securities Act;

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

          (iii)  upon notice of distribution issued by the Regular Trustees in
     accordance with the terms of the Preferred Securities and the Common
     Securities, engage in such ministerial activities as shall be necessary or
     appropriate to effect the distribution of the Subordinated Notes to Holders
     of Securities upon the Sponsor's election to dissolve the Trust in
     accordance with Section 8.1(a)(v).

     (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
the Securities and this Declaration.

     (e)  The Property Trustee shall have the power to take any Legal Action
which arises out of or in connection with an Event of Default or the Property
Trustee's duties and obligations under this Declaration, the Business Trust Act
or the Trust Indenture Act.  If the Property Trustee fails to enforce its rights
under the Subordinated Notes after a Holder of Preferred Securities has made a
written request, such Holder may, to the fullest extent permitted by law,
institute a legal proceeding against the Subordinated Notes Issuer, to enforce
the Property Trustee's rights under the Subordinated Notes, without first
instituting any legal proceeding against the Property Trustee or any other
person or entity.  Notwithstanding the foregoing, if an Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Subordinated Notes Issuer to pay interest, premium, if any, or principal on the
Subordinated Notes on the date such interest, premium, if any, or principal is
otherwise payable (or in the case of redemption, on the redemption date), then a
Holder of Preferred Securities may directly institute a proceeding for
enforcement of payment to such Holder of the principal of, premium, if any, or
interest on, the Subordinated Notes having a principal amount equal to the
aggregate liquidation amount of the Preferred Securities of such Holder (a
"Direct Action"). Notwithstanding any payments made to such Holder of Preferred
Securities by the Subordinated Notes Issuer in connection with a Direct Action,
the Subordinated Notes Issuer shall remain obligated to pay the principal of,
premium, if

                                      16

 
any, or interest on the Subordinated Notes held by the Trust or the Property
Trustee of the Trust, and the Subordinated Notes Issuer shall be subrogated to
the rights of the Holder of such Preferred Securities with respect to payments
on the Preferred Securities.  Except as provided in the preceding sentences and
in the Preferred Securities Guarantee, the Holders of Preferred Securities will

     (a)  The Property Trustee, before the occurrence of any Event of Default
and after the curing or waiver of all Events of Default that may have occurred:

          (i)  shall undertake to perform only such duties as are specifically
     set forth in this Declaration and in the terms of the Securities, and no
     implied covenants, duties or obligations shall be read into this
     Declaration against the Property Trustee; and

                                      17

 
          (ii) 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; but 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 they
     conform to the requirements of this Declaration.

In case an Event of Default has occurred (that has not been cured or waived
pursuant to Section 2.6), 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 or use, 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)    this Subsection shall not be construed to limit Subsection (a)
     of this Section;

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

          (iii)  the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of not less than a Majority in liquidation
     amount of the Securities at the time outstanding 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 including, without limitation, with
     respect to the Securities; and

          (iv)   no provision of this Declaration shall require the Property
     Trustee to expend or risk its own funds or otherwise incur financial
     liability in the performance of any of its duties hereunder or in the
     exercise of any of its rights or powers, if it shall have reasonable ground
     for believing that the repayment of such funds or adequate indemnity
     against such risk or liability is not reasonably assured to it.

     (c)  Whether or not therein expressly so provided, every provision of this
Declaration relating to the conduct or affecting the liability of or affording
protection to the Property Trustee shall be subject to the provisions of this
Section.

     document, but the Property Trustee, in its discretion, may make such
     further inquiry or investigation into such facts or matters as it may see

     inquiry or investigation, it shall be entitled to examine the books,
     records and premises of the Trust, personally or by agent or attorney;

     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 instructions are received,

described in Section 3.15(b) and (c);

     (b)  the Trust may, with the consent of a majority of the Regular Trustees
and without the consent of the Holders of the Securities, the Delaware Trustee
or the Property Trustee, consolidate, amalgamate, merge with or into, or be
replaced by a trust organized as such under the laws of any State; provided,
that if the Trust is not the surviving entity:

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

          (ii)   the Subordinated Notes Issuer expressly acknowledges a trustee
     of the Successor Entity which possesses the same powers and duties as the
     Property Trustee as the Holder of the Subordinated Notes;

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

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

                                      21

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

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

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

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

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

          (vii)  the Sponsor guarantees the obligations of such Successor Entity
     under the Successor Securities and Successor Common Securities at least to
     the extent provided by the Preferred Securities Guarantee and the Common
     Securities Guarantee, respectively; and

     (c)  notwithstanding Section 3.15(b), the Trust shall not (except with the
written consent of Holders of 100% of the outstanding Preferred Securities)
consolidate, amalgamate, merge with or into, or be replaced by any other entity
or permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger or replacement would
cause the Trust or Successor Entity to be classified as other than a grantor
trust for United States federal income tax purposes. Prior to such merger,
consolidation, amalgamation, or replacement, the Sponsor shall have received an
opinion of counsel to the Trust, experienced in such matters to the effect that
following such merger, consolidation, amalgamation or replacement, the Trust
will continue to be classified as grantor trust for United States federal income
tax purposes.

          (i)  no such resignation of the Trustee that acts as the Property
     Trustee shall be effective (A) until a Successor Property Trustee has been
     appointed and has accepted such appointment by instrument executed by such
     Successor Property Trustee and delivered to the Trust, the Sponsor and the
     resigning Property Trustee; or (B) until the assets of the Trust have been
     completely liquidated and the proceeds thereof distributed to the holders
     of the Securities; and

                                      26

 
          (ii) so long as a Delaware Trustee is required pursuant to Section
     5.1, no such resignation of the Trustee that acts as the Delaware Trustee
     shall be effective until a Successor Delaware Trustee has been appointed
     and has accepted such appointment by instrument executed by such Successor
     Delaware Trustee and delivered to the Trust, the Sponsor and the resigning
     Delaware Trustee.

     (d)  The Holders of the Common Securities shall use their best efforts to
promptly appoint a Successor Delaware Trustee (so long as a Delaware Trustee is
required pursuant to Section 5.1) or Successor Property Trustee, as the case may
be, if the Property Trustee or the Delaware Trustee delivers an instrument of
resignation in accordance with this Section 5.6.

     (e)  If no Successor Property Trustee or Successor Delaware Trustee shall
have been appointed and accepted appointment as provided in this Section 5.6
within 60 days after delivery of an instrument of resignation or removal, the
Property Trustee or Delaware Trustee resigning or being removed may petition any
court of competent jurisdiction for appointment of a Successor Property Trustee
or Successor Delaware Trustee. Such court may thereupon after such notice, if
any, as it may deem proper and prescribe, appoint a Successor Property Trustee
or Successor Delaware Trustee, as the case may be.

     Section 5.7  Vacancies Among Trustees.
                  ------------------------ 

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

     Section 5.8  Effect of Vacancies.
                  ------------------- 

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

     Section 5.9  Meetings.
                  -------- 

     Meetings of the Regular Trustees shall be held from time to time upon the
call of any Regular Trustee.  Regular meetings of the Regular Trustees may be
held at a time and place fixed by resolution of the Regular Trustees.  Notice of
any in-person meetings of the Regular Trustees shall be hand delivered or
otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 48 hours before such meeting.  Notice of any
telephonic meetings of the Regular Trustees or any committee thereof shall be
hand delivered or otherwise delivered in writing (including by facsimile, with a
hard copy by overnight courier) not less than 24 hours before a meeting.
Notices shall contain a brief statement of the time, place and anticipated
purposes of the meeting.  The presence (whether in person or by telephone) of a

                                      27

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

     Section 5.10  Delegation of Power.
                   ------------------- 

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

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

     Section 5.11  Merger, Conversion, Consolidation or Succession to Business.
                   ----------------------------------------------------------- 

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

                                 DISTRIBUTIONS

     Section 6.1  Distributions.
                  ------------- 

     Holders shall receive Distributions in accordance with the applicable terms
of the relevant Holder's Securities.  Distributions shall be made on the
Preferred Securities and the Common Securities in accordance with the
preferences set forth in their respective terms.  If and to the extent that the
Subordinated Notes Issuer makes a payment of interest (including Additional
Interest (as defined in the Indenture)), premium, if any, and principal on the
Subordinated Notes 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 

                                      28

 
the event the Sponsor shall defer any payment of principal, premium, if any, or
interest on the Subordinated Notes, the Trust shall, in like manner, defer
payments of Distributions on the Securities, and additional Distributions shall
accrue on such Securities for so long as the payment of principal, premium, if
any, or interest on the Subordinated Notes is deferred.

                                  ARTICLE VII

                            ISSUANCE OF SECURITIES

     Section 7.1  General Provisions Regarding Securities.
                  --------------------------------------- 

     (a)  The Regular Trustees shall, on behalf of the Trust, issue one class of
preferred securities representing undivided beneficial interests in the assets
of the Trust having such terms as are set forth in Exhibit A and incorporated
herein by reference (the "Preferred Securities"), and one class of common
securities representing undivided beneficial interests in the assets of the
Trust having such terms as are set forth in Exhibit A and incorporated herein by
reference (the "Common Securities").  The Trust shall have no securities or
other interests in the assets of the Trust other than the Preferred Securities
and the Common Securities;

     (b)  the Certificates shall be signed on behalf of the Trust by the Regular
Trustees (or if there are more than two Regular Trustees by any two of the
Regular Trustees).  Such signatures may be the manual or facsimile signatures of
the present or any future Regular Trustee.  Typographical and other minor errors
or defects in any such reproduction of any such signature shall not affect the
validity of any Certificate.  In case any Regular Trustee of the Trust who shall
have signed any of the Certificates shall cease to be such Regular Trustee
before the Certificate so signed shall be delivered by the Trust, such
Certificate nevertheless may be delivered as though the person who signed such
Certificate had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons who shall at the actual date of
execution of such Security, be the Regular Trustees of the Trust, although at
the date of the execution and delivery of the Declaration any such person was
not such a Regular Trustee.  Certificates shall be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Regular Trustees, as evidenced by their execution thereof, and may have such
letters, numbers or other marks of identification or designation and such
legends or endorsements as the Regular Trustees may deem appropriate, or as may
be required to comply with any law or with any rule or regulation of any stock
exchange on which Securities may be listed, or to conform to usage.  A Preferred
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 Preferred Security has been authenticated under this
Declaration.  Upon a written order of the Trust signed by one Regular Trustee,
the Property Trustee shall authenticate the Preferred Securities for original
issue.  The Property Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Preferred Securities.  An authenticating agent may
authenticate Preferred 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 to deal with the Trust or an Affiliate;

                                      29

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

     (d)  upon issuance of the Securities as provided in this Declaration, the
Securities so issued shall be deemed to be validly issued, fully paid and
nonassessable; and

     (e)  every Person, by virtue of having become a Holder or a Preferred
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.

                                 ARTICLE VIII

                     DISSOLUTION AND TERMINATION OF TRUST

     Section 8.1  Dissolution and Termination of Trust.
                  ------------------------------------ 

     (a)  The Trust shall dissolve and its affairs shall be wound up, upon the
earliest to occur of the following:

          (i)    upon the bankruptcy of the Sponsor or the Holder of the Common
     Securities;

          (ii)   upon the filing of a certificate of dissolution or its
     equivalent with respect to the Sponsor, the filing of a certificate of
     cancellation with respect to the Trust upon the consent (other than in
     connection with a dissolution of the Trust pursuant to clause (v) of this
     Section 8.1(a)) of the Holders of at least a Majority in liquidation amount
     of the Securities, voting together as a single class, to file such
     certificate of cancellation, or the revocation of the charter of the
     Sponsor or the Holder of the Common Securities and the expiration of 90
     days after the date of revocation without a reinstatement thereof;

          (iii)  upon the entry of a decree of judicial dissolution of the
     Sponsor or the Trust or the Holder of the Common Securities;

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

          (v)    upon the election by the Sponsor, effective upon notice to the
     Trust, the Property Trustee and the Delaware Trustee, to dissolve the Trust
     in accordance with the terms of the Securities and all of the Subordinated
     Notes held by the Property Trustee shall have been distributed to the
     Holders of Securities in exchange for all of the Securities;

          (vi)   upon the written direction to the Property Trustee from the
     Sponsor at any time to terminate the Trust and, after satisfaction of
     liabilities to creditors of the Trust as provided by applicable law, the
     distribution of Subordinated Notes to Holders in exchange for the
     Securities, subject to the Regular Trustees' receipt of an opinion of

                                      30

 
     counsel experienced in such matters to the effect that the Holders of the
     Preferred Securities will not recognize any income, gain or loss for United
     States federal income tax purposes as a result of the dissolution of the
     Trust and such distribution to Holders; or

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

     (b)  As soon as is practicable after the occurrence of an event referred to
in Section 8.1(a) or dissolution pursuant to Section 3.14 and upon the
completion of the winding up of the Trust, one of the Regular Trustees (each
Regular Trustee being hereby authorized to take such action) shall file a
certificate of cancellation with the Secretary of State of the State of Delaware
terminating the Trust.

     (c)  The provisions of Section 3.9 and Article X shall survive the
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 the terms of
the Securities.  Any transfer or purported transfer of any Security not made in
accordance with this Declaration shall be null and void;

     (b)  subject to this Article IX, Preferred Securities shall be freely
transferable; and

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

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

          (ii) the Trust would be an Investment Company required to register
     under the Investment Company Act or the transferee would become an
     Investment Company required to register under the Investment Company Act.

     (d)  Each Common Security that bears or is required to bear the legend set
forth in this Section 9.1(d) shall be subject to the restrictions on transfer
provided in the legend set forth in this Section 9.1(d), unless such
restrictions on transfer shall be waived by the written consent of the Regular
Trustees, and the Holder of each such Common Security, by such security holder's
acceptance thereof, agrees to be bound by such restrictions on transfer.  As
used in this 

                                      31

 
Section 9.1(d) and in Section 9.1(c), the term "transfer" encompasses any sale,
pledge, transfer or other disposition of any such Common Security.

     Any certificate evidencing a Common Security shall bear a legend in
substantially the following form, unless otherwise agreed by the Regular
Trustees (with written notice thereof to the Property Trustee):

     THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
     SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
     ACCORDINGLY, MAY NOT BE OFFERED OR SOLD UNLESS SUCH OFFER AND SALE ARE
     REGISTERED UNDER OR ARE EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT.
     THE TRANSFER OF THE SECURITY EVIDENCED HEREBY IS ALSO SUBJECT TO THE
     RESTRICTIONS SET FORTH IN THE DECLARATION REFERRED TO BELOW.

       Section 9.2  Transfer of Certificates.
                    ------------------------ 

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

     (b)  Notwithstanding any other provisions of this Declaration, a Global
Certificate may not be transferred as a whole, except by the Clearing Agency to
a 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.

     Section 9.3  Deemed Security Holders.
                  ----------------------- 

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

                                      32

 
     Section 9.4  Book Entry Interests.
                  -------------------- 

     (a)  So long as Preferred Securities are eligible for book entry settlement
with the Clearing Agency or unless otherwise required by law, all Preferred
Securities that are so eligible may be represented by one or more, fully
registered, global Preferred Security Certificates (each a "Global
Certificate"), to be delivered to DTC, the initial Clearing Agency, by, or on
behalf of, the Trust.  Such Global Certificates shall initially be registered on
the books and records of the Trust in the name of Cede & Co., the nominee of
DTC, and no Preferred Security Beneficial Owner will receive a definitive
Preferred Security Certificate representing such Preferred Security Beneficial
Owner's interests in such Global Certificates, except as provided in Section
9.7.  The transfer and exchange of beneficial interests in any such Security in
global form shall be effected through the Clearing Agency in accordance with
this Declaration and the procedures of the Clearing Agency therefor.

     (b)  Except as provided below, Beneficial Owners of a Preferred Security in
global form shall not be entitled to have certificates registered in their
names, will not receive or be entitled to receive physical delivery of
certificates in definitive form and will not be considered Holder of such
Preferred Security in global form.

     (c)  Any Global Certificate may be endorsed with or have incorporated in
the text thereof such legends or recitals or changes not inconsistent with the
provisions of this Declaration as may be required by the Clearing Agency, by any
national securities exchange or by the National Association of Securities
Dealers, Inc. as may be required to comply with any applicable law or any
regulation thereunder or with the rules and regulations of any securities
exchange or interdealer quotation system upon which the Preferred Securities may
be listed or traded or to conform with any usage with respect thereto, or to
indicate any special limitations or restrictions to which any particular
Preferred Securities are subject.

     (d)  Unless and until definitive, fully registered Preferred Security
Certificates (the "Definitive Preferred Security Certificates") have been issued
to the Preferred Security Beneficial Owners pursuant to Section 9.7:

          (i)    the provisions of this Section 9.4 shall be in full force and
     effect with respect to such Preferred Securities;

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

          (iii)  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

          (iv)   the rights of the Beneficial Owners of Preferred Securities in
     global form shall be exercised only through the Clearing Agency and shall
     be limited to those established by law and agreements between such
     Preferred Security Beneficial Owners and the Clearing Agency and/or the
     Clearing Agency Participants.  The Clearing Agency 

                                      33

 
     will make book entry transfers among the Clearing Agency Participants and
     receive and transmit payments of Distributions on the Global Certificates
     to such Clearing Agency Participants.  DTC will make book entry transfers
     among the Clearing Agency Participants, provided, that solely for the
     purposes of determining whether the Holders of the requisite amount of
     Preferred Securities have voted on any matter provided for in this
     Declaration, so long as Definitive Preferred Security Certificates have not
     been issued, the Trustees 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 Preferred Securities
     Beneficial Owners' votes or assigning the right to vote on any matter to
     any other Persons either in whole or in part.

     Notwithstanding any other provisions of this Declaration (other than the
provisions set forth in this Section 9.4(d)), a Preferred Security in global
form may not be transferred as a whole except by the Clearing Agency to a
nominee of the Clearing Agency or by a nominee of the Clearing Agency to the
Clearing Agency or another nominee to a successor Clearing Agency or a nominee
of such successor Clearing Agency.

     Section 9.5  Notices to Clearing Agency.
                  -------------------------- 

     Whenever a notice or other communication to the Preferred Security Holders
is required under this Declaration, unless and until Definitive Preferred
Security Certificates shall have been issued to the Preferred Security
Beneficial Owners pursuant to Section 9.7, the Trustees shall give all such
notices and communications, specified herein to be given to the Preferred
Security Holders, to the Clearing Agency, and shall have no notice obligations
to the Preferred Security Beneficial Owners.

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

     If any Clearing Agency notifies the Trust that it is unwilling or unable to
continue its services as securities depositary with respect to the Preferred
Securities if such Clearing Agency ceases to perform such services, or if at any
time such Clearing Agency ceases to be a clearing agency registered as such
under the Exchange Act when such Clearing Agency is required to be so registered
to act as such depositary, then the Regular Trustees may, in their sole
discretion, appoint a successor Clearing Agency with respect to such Preferred
Securities.

     Section 9.7  Definitive Preferred Security Certificates Under Certain
                  --------------------------------------------------------
Circumstances.
- ------------- 

     If:

     (a)  a Clearing Agency notifies the Trust that it is unwilling or unable to
continue its services as securities depositary with respect to the Preferred
Securities, if such Clearing Agency ceases to perform such services, or if at
any time such Clearing Agency ceases to be a clearing agency registered as such
under the Exchange Act when such Clearing Agency is required to be so registered
to act as such depositary, and a successor Clearing Agency is not appointed
within 90 days after such discontinuance pursuant to Section 9.6; or

                                      34

 
     (b)  the Regular Trustees (with the consent of the Sponsor) in their sole
discretion determine that the Preferred Securities in global form shall be
exchanged for certificated Preferred Securities;

     then:

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

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

     At such time as all interests in a Preferred Security in global form have
been redeemed, exchanged, repurchased or canceled, such Preferred Security in
global form shall be, upon receipt thereof, canceled by the Trust in accordance
with standing procedures and instructions of the Clearing Agency.

     Section 9.8  Mutilated, Destroyed, Lost or Stolen Certificates.
                  ------------------------------------------------- 

     If:

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

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

     then:

in the absence of notice that such Certificate shall have been acquired by a
bona fide purchaser, the Property Trustee or any Regular Trustee on behalf of
the Trust shall execute and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination.  In connection with the issuance of any new Certificate under this
Section 9.8, the Property Trustee or the Regular Trustees may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection 

                                      35

 
therewith.  Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

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

     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

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

     (b)  Unless otherwise expressly provided herein:

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

          (ii) whenever this Declaration or any other agreement contemplated
     herein or therein provide 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.

Indemnified Person harmless against, any loss, liability or expense incurred by
such Indemnified Person by reason of any act or omission performed or omitted by
such Indemnified Person without negligence or bad faith (or, in case of the
Property Trustee, except as set forth in Section 

                                      37

 
3.9) on behalf of the Trust and in a manner such Indemnified Person reasonably
believed to be within the scope of authority conferred on such Indemnified
Person by this Declaration;

     (b)  reasonable expenses (including reasonable legal fees and expenses)
incurred by an Indemnified Person in defending any claim, demand, action, suit
or proceeding shall, from time to time, be advanced by the Sponsor prior to the
final disposition of such claim, demand, action, suit or proceeding upon receipt
by the Sponsor of an undertaking by or on behalf of the Indemnified Person to
repay such amount if it shall be determined that the Indemnified Person is not
entitled to be indemnified as authorized in Section 10.4(a); and

     (c)  the provisions of this Section 10.4 shall survive the termination of
this Declaration or resignation or removal of any Trustee.

     Section 10.5  Outside Businesses.
                   ------------------ 

     Any Covered Person, the Sponsor, the Delaware Trustee and the Property
Trustee (subject to Section 5.3(c)) may engage in or possess an interest in
other business ventures of any nature or description, independently or with
others, similar or dissimilar to the business of the Trust, and the Trust and
the Holders of Securities shall have no rights by virtue of this Declaration in
and to such independent ventures or the income or profits derived therefrom, and
the pursuit of any such venture, even if competitive with the business of the
Trust, shall not be deemed wrongful or improper.  No Covered Person, the
Sponsor, the Delaware Trustee, or the 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 11.2  Certain Accounting Matters.
                   -------------------------- 

     (a)  At all times during the existence of the Trust, the Trust 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 

                                      38

 
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, by a
firm of independent certified public accountants selected by the Regular
Trustees of the Trust.

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

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

     Section 11.3  Banking.
                   ------- 

     The Trust shall maintain one or more bank accounts in the name and for the
sole benefit of the Trust; provided, however, that all payments of funds in
respect of the Subordinated Notes 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 Regular Trustees; provided, however, that
the Property Trustee shall designate the signatories for the Property Trustee
Account.

     Section 11.4  Withholding.
                   ----------- 

     The Trust 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 Trust shall file required forms with applicable jurisdictions
and, unless an exemption from withholding is properly established by a Holder,
shall remit amounts withheld with respect to the Holder to applicable
jurisdictions.  To the extent that the Trust is required to withhold and pay
over any amounts to any authority with respect to distributions or allocations
to any Holder, the amount withheld shall be deemed to be a distribution in the
amount of the withholding to the Holder.  In the event of any claimed over-
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.

               (C)  cause the Trust to be deemed to be an Investment Company
          which is required to be registered under the Investment Company Act;

          (ii)   at such time after the Trust has issued any Securities which
     remain outstanding, any amendment which would adversely affect the rights,
     privileges or preferences of any Holder of Securities may be effected only
     with such additional requirements as may be set forth in the terms of such
     Securities;

          (iii)  Section 9.1 (c) and this Section 12.1 shall not be amended
     without the consent of all of the Holders of the Securities;

          (iv)   Article IV shall not be amended without the consent of the

from time to time by the Holders of a Majority in liquidation amount of the
Common Securities and the Property Trustee, without the consent of the Holders
of the Preferred Securities, to:

          (i)  cure any ambiguity;

          (ii) correct or supplement any provision in this Declaration that may

     Investment Company Act.

     (c)  Subject to Section 12.1(a), this Declaration may be amended by the
Holders of a Majority in liquidation amount of the Common Securities and the
Property Trustee if:

     Securities consent to such amendment; and

          (ii) the Regular Trustees have received an opinion of counsel
     experienced in such matters to the effect that such amendment or the
     exercise of any power granted to the Regular 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.

     (d)  Any amendments of this Declaration shall become effective when notice
thereof is given to Holders of Securities.

     Section 12.2  Meetings of the Holders of Securities; Action by Written

any time by the Regular Trustees (or as provided in the terms of the Securities)
to consider and act on any matter on which Holders of such class of Securities
are entitled to act under the terms of this Declaration, the terms of the
Securities or the rules of any stock exchange on which the Preferred Securities
are listed or admitted for trading.  The Regular Trustees shall call a meeting
of the Holders of such class of Holders, if directed to do so by the Holders of
at least 25% in liquidation amount of the Securities of such class.  Such
direction shall be given by delivering to the Regular Trustees one or more calls
in a writing stating that the signing Holders of Securities wish to call a
meeting and indicating the general or specific purpose for which the meeting is
to be called.  Any Holders of Securities calling a meeting shall specify in
writing the Security Certificates held by the Holders of Securities exercising
the right to call a meeting and only those Securities specified shall be counted
for purposes of determining whether the required percentage set forth in the
second sentence of this paragraph has been met.

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

          (i)  notice of any such meeting shall be given to all the Holders of

                                      41

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

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

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

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

                                   EXHIBIT A

                                   TERMS OF
                  8.16% TRUST ORIGINATED PREFERRED SECURITIES
                   8.16% TRUST ORIGINATED COMMON SECURITIES

     Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust,
dated as of January 20, 1999 (as amended from time to time, the "Declaration"),
the designation, rights, privileges, restrictions, preferences and other terms
and provisions of the Preferred Securities and the Common Securities are set out
below (each capitalized term used but not defined herein has the meaning set
forth in the Declaration or, if not defined in such Declaration, as defined in
the Prospectus referred to below):

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

          a.   Preferred Securities. 21,000,000 Preferred Securities of the 
               --------------------     
Trust with an aggregate liquidation amount with respect to the assets of the
Trust of Five Hundred Twenty-Five Million Dollars ($525,000,000), and a
liquidation amount with respect to the assets of the Trust of $25 per Preferred
Security, are hereby designated for the purposes of identification only as
"8.16% Trust Originated Preferred Securities" (the "Preferred Securities"). The
Preferred Security Certificates evidencing the Preferred Securities shall be
substantially in the form attached hereto as Annex I, with such changes and
additions thereto or deletions therefrom as may be required by ordinary usage,
custom or practice or to conform to the rules of any stock exchange on which the
Preferred Securities are listed.

          b.   Common Securities. 649,485 Common Securities of the Trust with an
               -----------------                                                
aggregate liquidation amount with respect to the assets of the Trust of Sixteen
Million Two Hundred Thirty-Seven Thousand One Hundred Twenty-Five Dollars
($16,237,125), and a liquidation amount with respect to the assets of the Trust
of $25 per Common Security, are hereby designated for the purposes of
identification only as "8.16% Trust Originated Common Securities" (the "Common
Securities"). The Common Security Certificates evidencing the Common Securities
shall be substantially in the form attached hereto as Annex II, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice.

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

          a.   Periodic Distributions payable on each Security will be fixed at
a rate per annum of 8.16% (the "Coupon Rate") of the stated liquidation amount
of $25 per Security, such rate being the rate of interest payable on the
Subordinated Notes to be held by the Property Trustee. Distributions in arrears
for more than one quarterly period will bear interest thereon at the Coupon Rate
(to the extent permitted by applicable law). The term "Distributions" as used in
these terms includes such periodic cash distributions and any such interest
payable unless otherwise stated. A Distribution is payable only to the extent
that payments are made in respect of the Subordinated Notes held by the Property
Trustee. The amount of Distributions payable for any period will be computed for
any full quarterly Distribution period on the basis of a 360-day year of twelve
30-day months, and for any period shorter than a full quarterly Distribution
period

                                      A-1

 
for which Distributions are computed, Distributions will be computed on the
basis of the actual number of days elapsed in such a 30-day month.

          b.   Distributions on the Securities will be cumulative, will accrue
from January 20, 1999 and will be payable quarterly in arrears, on March 31,
June 30, September 30 and December 31 of each year, commencing on March 31,
1999, except as otherwise described below. The Subordinated Notes Issuer has the
right under the Indenture to defer payments of interest by extending the
interest payment period from time to time on the Subordinated Notes for a period
not exceeding 20 consecutive quarterly periods (each, an "Extension Period") but
not beyond the maturity date of the Subordinated Notes and, as a consequence of
such extension, Distributions will also be deferred. Despite such deferral,
quarterly Distributions will continue to accrue with interest thereon (to the
extent permitted by applicable law) at the Coupon Rate during any such Extension
Period. Prior to the termination of any such Extension Period, the Subordinated
Notes Issuer may further extend such Extension Period; provided that such
Extension Period together with all such previous and further extensions thereof
may not exceed 20 consecutive quarterly periods. Payments of accrued
Distributions will be payable to Holders as they appear on the books and records
of the Trust on the first record date after the end of the Extension Period.
Upon the termination of any Extension Period and the payment of all amounts then
due, the Subordinated Notes 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 relevant
record dates.  While the Preferred Securities remain in book entry only form,
the relevant record dates shall be one Business Day prior to the relevant
payment dates which payment dates correspond to the interest payment dates on
the Subordinated Notes. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment in respect of the Preferred
Securities will be made as described under the heading "Certain Terms of the
Preferred Securities -- Book-Entry-Only Issuance -- The Depository Trust
Company" in the Prospectus Supplement dated January 13, 1999 (the "Prospectus
Supplement") to the Prospectus dated January 8, 1999 (as so supplemented the
"Prospectus") of the Trust included in the Registration Statement on Form S-3 of
the Sponsor, the Trust and certain other business trusts.  The relevant record
dates for the Common Securities shall be the same record dates as for the
Preferred Securities. If the Preferred Securities shall not continue to remain
in book entry only form, the relevant record dates for the Preferred Securities,
shall conform to the rules of any securities exchange on which the securities
are listed and, if none, shall be the 15/th/ day of the last month of each
quarterly distribution period, even if that day is not a Business Day.
Distributions payable on any Securities that are not punctually paid on any
Distribution payment date, as a result of the Subordinated Notes Issuer having
failed to make a payment under the Subordinated Notes, will cease to be payable
to the Person in whose name such Securities are registered on the relevant
record date, and such defaulted Distribution will instead be payable to the
Person in whose name such Securities are registered on the special record date
or other specified date determined in accordance with the Indenture. If any date
on which Distributions are payable on the Securities is not a Business Day, then
payment of the Distribution payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, such payment shall be 

                                      A-2

 
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date.

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

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

     In the event of any voluntary or involuntary dissolution, winding-up or
termination of the Trust, the Holders of the Securities on the date of the
dissolution, winding-up or termination, as the case may be, will be entitled to
receive out of the assets of the Trust available for distribution to Holders of
Securities, after paying or making reasonable provision to pay all claims and
obligations of the Trust in accordance with Section 3808(e) of the Business
Trust Act, an amount equal to the aggregate of the stated liquidation amount of
$25 per Security plus accrued and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution"), unless, in
connection with such dissolution, winding-up or termination, Subordinated Notes
in an aggregate principal amount equal to the aggregate stated liquidation
amount of such Securities, with an interest rate equal to the Coupon Rate of,
and bearing accrued and unpaid interest in an amount equal to the accrued and
unpaid Distributions on, such Securities, shall be distributed on a Pro Rata
basis to the Holders of the Securities in exchange for such Securities, after
paying or making reasonable provision to pay all claims and obligations of the
Trust in accordance with Section 3808(e) of the Business Trust Act.

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

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

          a.   Upon the repayment of the Subordinated Notes in whole or in part,
whether at maturity or upon redemption, the proceeds from such repayment or
payment shall be simultaneously applied to redeem Securities having an aggregate
liquidation amount equal to the aggregate principal amount of the Subordinated
Notes so repaid or redeemed, at the redemption price for the Subordinated Notes,
payable in cash (the "Redemption Price").  Holders will be given not less than
30 nor more than 60 days notice of such redemption.

          b.   If fewer than all the outstanding Securities are to be so
redeemed, the Common Securities and the Preferred Securities will be redeemed
Pro Rata and the Preferred Securities to be redeemed will be as described in
Paragraph 4(h)(ii) below.

          c.   The Subordinated Notes are redeemable, in whole or in part, at
the option of the Subordinated Notes Issuer, on one or more occasions, at any
time on or after January 20, 2004, at a redemption price equal to 100% of the
principal amount per Subordinated Note, plus, in each case, accrued and unpaid
interest thereon at the date of the redemption for the Subordinated Notes.

                                      A-3

 
          d.   If, at any time, a Tax Event or an Investment Company Event (each
as defined below, and each a "Special Event") shall occur and be continuing, the
Subordinated Notes Issuer shall have the right, upon not less than 30 nor more
than 60 days notice, to redeem the Subordinated Notes in whole or in part, for
cash within 90 days following the occurrence of such Special Event, at a
redemption price equal to 100% of the principal amount to be redeemed plus any
accrued and unpaid interest thereon to the date of such redemption and,
following such redemption, Securities with an aggregate liquidation amount equal
to the aggregate principal amount of the Subordinated Notes so redeemed shall be
redeemed by the Trust at the Redemption Price on a Pro Rata basis in accordance
with paragraph 8 hereof. The Common Securities will be redeemed Pro Rata with
the Preferred Securities, except that if an Event of Default has occurred and is
continuing, the Preferred Securities will have priority over the Common
Securities with respect to payment of the Redemption Price.

          e.   The following terms used herein shall be defined as follows:

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

               (ii) "Tax Event" means that the Trust shall have received an
opinion of counsel experienced in such matters to the effect that on or after
the date of the Prospectus Supplement, as a result of (a) any amendment to, or
change (including any announced proposed change) in, the laws (or any
regulations thereunder) of the United States or any political subdivision or
taxing authority thereof or therein, or (b) any official or administrative
pronouncement or action, or judicial decision, interpreting or applying such
laws or regulations, where such change or amendment becomes effective, or such
pronouncement, action or decision is announced or occurs, in each case on or
after the date of the Prospectus Supplement, 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 interest
accrued or received on the Subordinated Notes, (ii) the Trust is, or will be
within 90 days of the date of such opinion, subject to more than a minimal
amount of other taxes, duties, assessments or other governmental charges, or
(iii) interest payable by the Subordinated Notes Issuer to the Trust on the
Subordinated Notes is not, or within 90 days of the date of such opinion will
not be, deductible, in whole or in part, by the Subordinated Notes Issuer for
United States federal income tax purposes.

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

                                      A-4

 
          g.   In the event that the Sponsor makes the election referred to in
Section 8.1(a)(v) of the Declaration, the Regular Trustees shall dissolve the
Trust and, after paying or making reasonable provision to pay all claims and
obligations of the Trust in accordance with Section 3808(e) of the Business
Trust Act, cause Subordinated Notes, held by the Property Trustee, having an
aggregate stated liquidation amount of, with an interest rate identical to the
Coupon Rate of, and accrued and unpaid interest equal to accrued and unpaid
Distributions on and having the same record date for payment, as the Securities,
to be distributed to the Holders of the Securities in liquidation of such
Holders' interests in the Trust on a Pro Rata basis in accordance with paragraph
8 hereof. On and from the date fixed by the Regular Trustees for any
distribution of Subordinated Notes and dissolution of the Trust:  (i) the
Securities will no longer be deemed to be outstanding, (ii) The Depository Trust
Company (the "Depository") or its nominee (or any successor Clearing Agency or
its nominee), as the record Holder of the Preferred Securities, will receive a
registered global certificate or certificates representing the Subordinated
Notes to be delivered upon such distribution and (iii) any certificates
representing Securities, except for certificates representing Preferred
Securities held by the Depository or its nominee (or any successor Clearing
Agency or its nominee), will be deemed to represent beneficial interests in the
Subordinated Notes having an aggregate principal amount equal to the aggregate
stated liquidation amount of, with an interest rate identical to the Coupon Rate
of, and accrued and unpaid interest equal to accrued and unpaid Distributions on
such Securities until such certificates are presented to the Subordinated Notes
Issuer or its agent for transfer or reissue. If the Subordinated Notes are
distributed to Holders of the Securities, pursuant to the terms of the
Indenture, the Subordinated Notes Issuer will use its best efforts to have the
Subordinated Notes listed on the New York Stock Exchange or on such other
exchange as the Preferred Securities were listed immediately prior to the
distribution of the Subordinated Notes.

          h.   Redemption or Distribution Procedures.
               ------------------------------------- 

               (i)  Notice of any redemption of, or notice of distribution of
Subordinated Notes 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 Subordinated Notes.  For purposes
of the calculation of the date of redemption or exchange and the dates on which
notices are given pursuant to this paragraph 4(h)(i), a Redemption/Distribution
Notice shall be deemed to be given on the day such notice is first mailed, by
first-class mail, postage prepaid, to Holders of Securities. Each
Redemption/Distribution Notice shall be addressed to the Holders of Securities
at the address of each such Holder appearing in the books and records of the
Trust. No defect in the Redemption/Distribution Notice or in the mailing of
either thereof with respect to any Holder shall affect the validity of the
redemption or exchange proceedings with respect to any other Holder.

               (ii)  In the event that fewer than all the outstanding Securities
are to be redeemed, the Securities to be redeemed will be redeemed Pro Rata from
each Holder of Securities, it being understood that, in respect of Preferred
Securities registered in the name of and held of record by the Depository (or
any successor Clearing Agency) or any other nominee, the distribution of the
proceeds of such redemption will be made to each Clearing Agency

                                      A-5

 
Participant (or person on whose behalf such nominee holds such securities) in
accordance with the procedures applied by such agency or nominee.

               (iii)  If Securities are to be redeemed and the Trust gives a
Redemption/Distribution Notice which notice may only be issued if the
Subordinated Notes are redeemed as set out in this paragraph 4 (which notice
will be irrevocable) then (A) while the Preferred Securities are in book entry
only form, with respect to the Preferred Securities, by 12:00 noon, New York
City time, on the redemption date, provided that the Subordinated Notes Issuer
has paid the Property Trustee a sufficient amount of cash in connection with the
related redemption or maturity of the Subordinated Notes, the Property Trustee
will deposit irrevocably with the Depository (or successor Clearing Agency)
funds sufficient to pay the Redemption Price with respect to the Preferred
Securities and will give the Depository irrevocable instructions and authority
to pay the Redemption Price to the Holders of the Preferred Securities, and (B)
if the Preferred Securities are issued in definitive form, with respect to the
Preferred Securities, and with respect to the Common Securities, provided that
the Subordinated Notes Issuer has paid the Property Trustee a sufficient amount
of cash in connection with the related redemption or maturity of the
Subordinated Notes, the Property Trustee will pay the Redemption Price to the
Holders of such Securities by check mailed to the address of the relevant Holder
appearing on the books and records of the Trust on the redemption date. If a
Redemption/Distribution Notice shall have been given and funds deposited as
required, if applicable, then immediately prior to the close of business on the
date of such deposit, or on the redemption date, as applicable, Distributions
will cease to accrue on the Securities so called for redemption and all rights
of Holders of such Securities 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. Neither the Regular Trustees nor the
Trust shall be required to register or cause to be registered the transfer of
any Securities which have been so called for redemption.  If any date fixed for
redemption of Securities is not a Business Day, then payment of the Redemption
Price payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that, if such Business Day falls in the next calendar year, such
payment will be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date fixed for redemption.  If
payment of the Redemption Price in respect of 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 accrue, from the original redemption date to the
actual date of payment, in which case the actual payment date will be considered
the date fixed for redemption for purposes of calculating the Redemption Price.

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

               (v)    Subject to the foregoing and applicable law (including,
without limitation, United States federal securities laws), provided the
acquiror is not the Holder of the Common Securities or the obligor under the
Indenture, the Sponsor or any of its subsidiaries may 

                                      A-6

 
at any time and from time to time purchase outstanding Preferred Securities by
tender, in the open market or by private agreement.

     5.   Voting Rights Applicable to Preferred Securities.
          ------------------------------------------------ 

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

          b.   Subject to the requirements of the third to last sentence of this
paragraph, the Holders of a Majority in liquidation amount of the Preferred
Securities, voting separately as a class, may direct 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 the
Declaration, including (i) directing the time, method, and place of conducting
any proceeding for any remedy available to the Subordinated Notes Trustee, or
exercising any trust or power conferred on the Subordinated Notes Trustee with
respect to the Subordinated Notes, (ii) waiving any past default and its
consequences that is waivable under Section 513 of the Indenture, (iii)
exercising any right to rescind or annul a declaration that the principal of all
the Subordinated Notes shall be due and payable or (iv) consenting to any
amendment, modification or termination of the Indenture or the Subordinated
Notes where such consent shall be required, provided, however, that where a
consent under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Subordinated Notes affected
thereby (a "Super Majority"), the Property Trustee may only give such consent or
take such action at the direction of the Holders of at least the proportion in
liquidation amount of the Preferred Securities which the relevant Super Majority
represents of the aggregate principal amount of the Subordinated Notes
outstanding. The Property Trustee shall not revoke any action previously
authorized or approved by a vote of the Holders of the Preferred Securities.
Other than with respect to directing the time, method and place of conducting
any remedy available to the Property Trustee or the Subordinated Notes Trustee
as set forth above, the Property Trustee shall not take any action in accordance
with the directions of the Holders of the Preferred Securities under this
paragraph unless the Property Trustee has obtained an opinion of counsel to the
effect that for the purposes of United States federal income tax the Trust will
not be classified as other than a grantor trust on account of such action. If
the Property Trustee fails to enforce its rights under the Declaration, any
Holder of Preferred Securities may institute a legal proceeding directly against
any Person to enforce the Property Trustee's rights under the Declaration,
without first instituting a legal proceeding against the Property Trustee or any
other Person. Notwithstanding the foregoing, if an Event of Default has occurred
and is continuing with respect to the Preferred Securities and such event is
attributable to the failure of the Subordinated Notes Issuer to pay interest,
premium, if any, or principal on the Subordinated Notes on the date such
interest, premium, if any, or principal is otherwise payable (or in the case of
redemption, on the redemption date), then a holder of Preferred Securities may
institute a Direct Action for enforcement of payment to such holder of the
principal of, premium, if any, or interest on, Subordinated Notes having a
principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder on or after the respective due date specified in the
Subordinated Notes. Notwithstanding any payments made to such Holder of
Preferred Securities by the Subordinated Notes Issuer in connection with a
Direct Action, the Subordinated Notes Issuer shall remain obligated to pay the
principal of, premium, if any, and interest on the Subordinated Notes held by
the Trust or the Property Trustee, and the Subordinated Notes Issuer

                                      A-7

 
shall be subrogated to the rights of the Holder of such Preferred Securities
with respect to payments on the Preferred Securities to the extent of any
payment made by the Subordinated Notes Issuer to such Holder in any Direct
Action.  Except as provided in the preceding sentences, the Holders of Preferred
Securities will not be able to exercise directly any other remedy available to
the holders of the Subordinated Notes.

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

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

          e.   Notwithstanding that Holders of Preferred Securities are entitled
to vote or consent under any of the circumstances described above, any of the
Preferred 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 With Respect to Common Securities.
          ----------------------------------------------- 

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

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

          c.   Subject to Section 2.6 of the Declaration and only after all
Events of Default with respect to the Preferred Securities have been cured,
waived or otherwise eliminated and subject to the requirements of the second to
last sentence of this paragraph, the Holders of a Majority in liquidation amount
of the Common Securities, voting separately as a class, may direct the time,
method, and place of conducting any proceeding for any remedy available to the
Property Trustee, or exercising any trust or power conferred upon the Property
Trustee under the Declaration, including (i) directing the time, method, place
of conducting any proceeding for any remedy available to the Subordinated Notes
Trustee, or exercising any trust or power conferred on the Subordinated Notes
Trustee with respect to the Subordinated Notes, (ii) waiving any past default
and its consequences that is waivable under Section 513 of the Indenture, or
(iii) exercising any right to rescind or annul a declaration that the principal
of all the Subordinated

                                      A-8

 
Notes shall be due and payable, provided, however, that where a consent or
action under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Subordinated Notes affected
thereby (a "Super Majority"), the Property Trustee may only give such consent or
take such action at the direction of the Holders of at least the proportion in
liquidation amount of the Common Securities which the relevant Super Majority
represents of the aggregate principal amount of the Subordinated Notes
outstanding. Pursuant to this paragraph 6(c), the Property Trustee shall not
revoke any action previously authorized or approved by a vote of the Holders of
the Common Securities. Other than with respect to directing the time, method and
place of conducting any remedy available to the Property Trustee or the
Subordinated Notes Trustee as set forth above, the Property Trustee shall not
take any action in accordance with the directions of the Holders of the Common
Securities under this paragraph unless the Property Trustee has obtained an
opinion of counsel to the effect that for the purposes of United States federal
income tax the Trust will not be classified as other than a grantor trust on
account of such action. If the Property Trustee fails to enforce its rights
under the Declaration, any Holder of Common Securities may, to the fullest
extent permitted by law, institute a legal proceeding directly against any
Person to enforce the Property Trustee's rights under the Declaration, without
first instituting a legal proceeding against the Property Trustee or any other
Person. Notwithstanding the foregoing, if an Event of Default has occurred and
is continuing with respect to the Common Securities and such event is
attributable to the failure of the Subordinated Notes Issuer to pay interest or
principal on the Subordinated Notes on the date such interest or principal is
otherwise payable (or in the case of redemption, on the redemption date), then a
holder of Common Securities may institute a proceeding for enforcement of
payment to such holder of the principal of, or interest on, Subordinated Notes
having a principal amount equal to the aggregate liquidation amount of the
Common Securities of such holder on or after the respective due date specified
in the Subordinated Notes.

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

          e.   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 Subordinated Notes in accordance with the Declaration and the
terms of the Securities.

     7.   Amendments to Declaration and Indenture.
          --------------------------------------- 

          a.   In addition to any requirements under Section 12.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the

                                      A-9

 
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 or Section 3.14 of the Declaration, then the Holders of outstanding
Securities as a class, will be entitled to vote on such amendment or proposal
(but not on any other amendment or proposal) and such amendment or proposal
shall not be effective except with the approval of the Holders of at least a
Majority in liquidation amount of the Securities, voting together as a single
class; provided, however, that if any amendment or proposal referred to in
clause (i) above would adversely affect only the Preferred Securities or the
Common Securities, then only the affected class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a Majority in liquidation amount of such class of
Securities.

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

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

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

     9.   Ranking.
          ------- 

     The Preferred Securities rank pari passu and payment thereon shall be made
Pro Rata with the Common Securities except that, where an Event of Default
occurs and is continuing 

                                     A-10

 
under the Indenture in respect of the Subordinated Notes held by the Property
Trustee, the rights of Holders of the Common Securities to payment in respect of
Distributions and payments upon liquidation, redemption and otherwise are
subordinated to the rights to payment of the Holders of the Preferred
Securities.

     10.  Acceptance of Securities Guarantee and Indenture.
          ------------------------------------------------ 

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

     11.  No Preemptive Rights.
          -------------------- 

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

     12.  Miscellaneous.
          ------------- 

     These terms constitute a part of the Declaration.

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

                                    Annex I

Preferred Security is a Global Certificate within the meaning of the Declaration
hereinafter referred to and is registered in the name of The Depository Trust

Security is exchangeable for Preferred Securities registered in the name of a
person other than the Depository or its nominee only in the limited

Security (other than a transfer of this Preferred Security as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository) may be registered except in
limited circumstances.

     Unless this Preferred Security is presented by an authorized representative
of The Depository Trust Company (55 Water Street, New York) to the Trust or its
agent for registration of transfer, exchange or payment, and any Preferred
Security issued is registered in the name of Cede & Co. or such other name as
requested by an authorized representative of The Depository Trust Company and
any payment hereon is made to Cede & Co., ANY TRANSFER, PLEDGE OR OTHER USE
HEREOF FOR VALUE OR OTHERWISE BY A PERSON IS WRONGFUL since the registered owner
hereof, Cede & Co., has an interest herein.]
