                                     PART I


ITEM 1.  BUSINESS.

         Enron Capital Trust I (the "Trust") is a statutory business trust
created under the Delaware Business Trust Act, as amended (the "Trust Act"),
pursuant to an amended and restated declaration of trust (the "Declaration") and
the filing of a certificate of trust with the Secretary of State of the State of
Delaware. The Trust's sole assets are 8,247,440 8.30% Partnership Preferred
Securities ($25 liquidation amount per security) representing an 85% limited
partnership interest in Enron Preferred Funding, L.P., a Delaware limited
partnership (the "Partnership"). Ownership of the assets of the Trust is
evidenced by an aggregate of 8,000,000 8.30% Trust Preferred Securities (the
"Trust Preferred Securities"), which are listed and traded on the New York Stock
Exchange under the symbol "ENE PrT", and 247,440 Trust Common Securities (the
"Trust Common Securities," and, together with the Trust Preferred Securities,
the "Trust Securities"), all of which are owned by Enron Corp., a Delaware
corporation ("Enron"). The Trust makes distributions on the Trust Securities to
the extent it receives distributions from the Partnership on the Partnership
Preferred Securities. Payments on the Partnership Preferred Securities represent
the sole source of revenue for the Trust. Distributions on the Trust Securities
are guaranteed by Enron, but only to the extent that the Trust has available
funds to pay such distributions. The Trust was created for the sole purpose of
issuing the Trust Securities, investing the proceeds of such issuance in the
Partnership Preferred Securities and engaging in only those other activities
necessary or incidental thereto. The Trust Securities are subject to redemption
at any time on or after March 31, 2002 and earlier in the event of certain tax
law changes or other events.

         The general partner of the Partnership is Enron, which owns a 15%
general partnership interest in the Partnership. Since completion of the
offering of the Trust Preferred Securities on November 21, 1996, the assets of
the Partnership have been invested primarily in a $181,926,000 principal amount
7.75% Subordinated Debenture due 2016 of Enron (the "Enron Debenture") and
$29,108,000 principal amount 7.75% Debentures due 2016 of each of Enron Capital
& Trade Resources Corp. and Enron Pipeline Company (the "Subsidiary Debentures"
and, together with the Enron Debenture, the "Debentures"), each of which is a
wholly owned subsidiary of Enron. The obligations under the Subsidiary
Debentures are guaranteed by Enron. The respective issuers of the Debentures
have certain rights to elect to defer any payments of principal and interest on
the Debentures for up to five years at a time. In addition to the Debentures,
the Partnership owns an aggregate of approximately $2,685,000 in short-term,
investment grade debt securities (the "Eligible Debt Securities"). Under certain
circumstances, upon repayment of one or more of the Debentures, the assets of
the Partnership may be reinvested in one or more debt securities of Enron or its
subsidiaries. Payments of interest and principal on the Enron Debenture and the
Subsidiary Debentures (or the guarantees thereof) and the Eligible Debt
Securities are the sole source of revenue for the Partnership. The Partnership
pays distributions to the Trust as holder of the Partnership Preferred
Securities when as and if Enron, as the general partner, determines to do so,
although Enron has no obligation to do so.

         For more information concerning the Trust, the Partnership and the
rights of the holders of the Trust Securities, see the Amended and Restated
Declaration of Trust relating to the Trust, the Amended and Restated Agreement
of Limited Partnership relating to the Partnership, the Indentures relating to
each of the Debentures and the Guarantee Agreements of Enron with respect to the
Trust Preferred Securities, the Partnership Preferred Securities and the
Subsidiary Debentures, each of which is included as an exhibit to this Form
10-K.

          Enron, a Delaware corporation organized in 1930, is an integrated
natural gas and electricity company headquartered in Houston, Texas. The common
stock of Enron is traded on the New York Stock Exchange under the symbol "ENE."
Essentially all of Enron's operations are conducted through its subsidiaries and
affiliates, which are principally engaged in the gathering, transportation and
wholesale marketing of natural gas to markets throughout the United States and
internationally through approximately 36,000 miles of natural gas pipelines; the
exploration for and production of natural gas and crude oil in the United States
and internationally; the production, purchase, transportation and worldwide
marketing of natural gas liquids and refined petroleum products; the independent
(i.e., non-utility) development, promotion, construction and operation of power
plants, natural gas liquids facilities and pipelines in the United States and
internationally; and the non-price regulated purchasing and marketing of
electricity and other energy related commitments.

      The location of the principal executive offices of the Trust and the
Partnership is c/o Enron Corp., 1400 Smith Street, Houston, Texas 77002, and its
phone number at such address is (713) 853-6161.

      NOTE: Because the Trust and the Partnership are special purpose financing
entities with no separate business operations, the only assets of the Trust are
the Partnership Preferred Securities, and substantially all of the assets of the
Partnership consist of a debt security of Enron and debt securities of
subsidiaries of Enron that are guaranteed by Enron, the Trust does not believe
that financial statements for the Trust or the Partnership are meaningful.
Accordingly, financial statements and related financial information have not
been included in this Form 10-K. For further information concerning Enron and
its subsidiaries, including financial statements and other financial
information, see the Annual Report on Form 10-K of Enron for the year ended
December 31, 1996 as filed with the Securities and Exchange Commission, a copy
of which may be obtained from the corporate secretary of Enron at the address
listed on the cover of this Form 10-K.

         MATTERS.

      Since approximately November 21, 1996, the Trust Preferred Securities have

From such date through December 31, 1996, the high and low sales prices of the
Trust Preferred Securities on the NYSE were $25.75 and

$24.75, respectively. As of March 14, 1997, the approximate number of holders of
record of the Trust Preferred Securities was 102. All of the Trust Common
Securities are held by Enron.

On December 31, 1996, the Trust made the first scheduled regular quarterly
distribution on the Trust Securities of $.23056 per Trust Security, such initial
distribution accruing from November 21, 1996, the date of original issuance of
the Trust Securities. The Trust expects to pay distributions on the Trust
Securities of $.51875 per quarter to the extent the Trust has funds available
for the payment of such distributions.

      The Trust issued an aggregate of 247,440 Trust Common Securities to Enron
on November 21, 1996 in a transaction exempt from the Securities Act of 1933
pursuant to Section 4(2) thereof.

           The Trust is administered by five trustees (the "Trustees"). Three of
the Trustees, Keith A. Crane, Lea W. Fastow and Phillip M. Sisneros (the
"Regular Trustees") are employees of Enron or its subsidiaries. The fourth
trustee is The Chase Manhattan Bank, which is unaffiliated with Enron and acts
as indenture trustee for purposes of compliance with the provisions of the Trust
Indenture Act (the "Property Trustee"). The fifth trustee, Chase Manhattan Bank
Delaware, is also unaffiliated with Enron and serves as Delaware Trustee to
fulfill a requirement of the Trust Act.

ITEM 11.  EXECUTIVE COMPENSATION.

          The Regular Trustees are not compensated by the Trust or Enron for

         this Section 2.6(b), the Trust Enforcement Event under this
         Declaration shall also not be waivable; or

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

                                       9

provided further, each Holder of Trust Common Securities will be deemed to have
waived any such Trust Enforcement Event and all Trust Enforcement Events with
respect to the Trust Common Securities and its consequences until all Trust
Enforcement Events with respect to the Trust Preferred Securities have been
cured, waived or otherwise eliminated, and until such Trust Enforcement Events
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 Trust Preferred
Securities and only the Holders of the Trust Preferred Securities will have the
right to direct the Property Trustee in accordance with the terms of the Trust
Securities.  The foregoing provisions of this Section 2.6(b) shall be in lieu
of Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby
expressly excluded from this Declaration and the Trust 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
Trust Enforcement Event with respect to the Trust 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 Trust Enforcement Event with respect to the Trust Common Securities or
impair any right consequent thereon.

         (c)     A waiver of Partnership Enforcement Events under the Limited
Partnership Agreement by the Property Trustee at the direction of the Holders
of the Trust Preferred Securities constitutes a waiver of the corresponding
Trust Enforcement Event under this Declaration.  The foregoing provisions of
this Section 2.6(c) shall be in lieu of Section 316(a)(1)(B) of the Trust
Indenture Act and such Section 316(a)(1)(B) of the Trust Indenture Act is
hereby expressly excluded from this Declaration and the Trust Securities, as
permitted by the Trust Indenture Act.

SECTION 2.7      Trust Enforcement Event; Notice.

         The Property Trustee shall, within 90 days after the occurrence of a
Trust Enforcement Event, transmit by mail, first class postage prepaid, to the
Holders of the Trust Securities, notices of all defaults with respect to the
Trust Securities actually known to a Responsible Officer of the Property
Trustee, unless such defaults have been cured before the giving of such notice
(the term "defaults" for the purposes of this Section 2.7 being hereby defined
to be defaults as defined in the Trust Guarantees or the Limited Partnership
Agreement, 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 Affiliate Investment Instruments or in the payment of
any sinking fund installment established for the Affiliate Investment
Instruments, the Property Trustee shall be protected in withholding such notice
if and so long as a Responsible Officer of the Property Trustee in good faith
determines that the withholding of such notice is in the interests of the
Holders of the Trust Securities.

         (f)     The Property Trustee shall have the legal power to exercise
all of the rights, powers and privileges of a Holder of Partnership Preferred

Enforcement Event and after the curing or waiver of all Trust Enforcement
Events that may have occurred, shall undertake to perform only such duties as
are specifically set forth in this Declaration and no implied covenants shall

Enforcement Event has occurred (that has not been cured or waived pursuant to
Section 2.6) of which a Responsible Officer of the Property Trustee has actual
knowledge, the Property Trustee shall exercise such of the rights and powers
vested in it by this Declaration, and use the same degree of care and skill in
their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

the Property Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:

                 (i)      prior to the occurrence of a Trust Enforcement Event

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

                          (B)     in the absence of bad faith on the part of
                 the Property Trustee, the Property Trustee may conclusively
                 rely, as to the truth of the statements and the correctness of
                 the opinions expressed therein, upon any certificates or
                 opinions furnished to the Property Trustee and conforming to
                 the requirements of this Declaration; but in the case of any
                 such certificates





                                       15
<PAGE>   21
                 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;

                 (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)    subject to the requirement of the Property Trustee
         receiving a tax opinion as set forth in Section 8.4(d) or 8.5(c), as
         the case may be, 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 Trust Securities relating to the
         time, method and place of conducting any proceeding for any remedy
         available to the Property Trustee, or exercising any trust or power
         conferred upon the Property Trustee under this Declaration;

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

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

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

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

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

         notice, request, direction, consent, order, bond, debenture, note,

         proper party or parties;

                 (ii)     any direction or act of the Sponsor or the Regular

                                       16
<PAGE>   22
                 (iii)    whenever in the administration of this Declaration,
         the Property Trustee shall deem it desirable that a matter be proved
         or established before taking, suffering or omitting any action
         hereunder, the Property Trustee (unless other evidence is herein
         specifically prescribed) may, in the absence of bad faith on its part,
         request and conclusively rely upon an Officers' Certificate which,
         upon receipt of such request, shall be promptly delivered by the
         Sponsor or the Regular Trustees;

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

                 (v)      the Property Trustee may, at the expense of the
         Sponsor, consult with counsel or other experts and the advice or
         opinion of such counsel and experts with respect to legal matters or
         advice within the scope of such experts' area of expertise shall be
         full and complete authorization and protection in respect of any
         action taken, suffered or omitted by it hereunder in good faith and in
         accordance with such advice or opinion; such counsel may be counsel to
         the Sponsor or any of its Affiliates, and may include any of its
         employees.  The Property Trustee shall have the right at any time to
         seek instructions concerning the administration of this Declaration
         from any court of competent jurisdiction;

                 (vi)     the Property Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Declaration
         at the request or direction of any Holder, unless (a) such Holder
         shall have provided to the Property Trustee security and indemnity,
         reasonably satisfactory to the Property Trustee, against the fees,
         charges, costs, expenses (including attorneys' fees and expenses and
         the expenses of the Property Trustee's agents, nominees or custodians)
         and liabilities that might be incurred by it in complying with such
         request or direction, including such reasonable advances as may be
         requested by the Property Trustee and (b) the Property Trustee has
         obtained the legal opinions, if any, required by Section 8.4(d) or
         8.5(c), as the case may be, of this Agreement; provided, that, nothing
         contained in this Section 3.10(a)(vi) shall be taken to relieve the
         Property Trustee, upon the occurrence of a Trust Enforcement Event, of
         its obligation to exercise the rights and powers vested in it by this
         Declaration;

                 (vii)    the Property Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Property Trustee, in
         its discretion, may make such further inquiry or investigation into
         such facts or matters as it may see fit;

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

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

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





                                       17
<PAGE>   23
         other action until such instructions are received, and (iii) shall be
         protected in conclusively relying on or acting in accordance with such
         instructions; provided, however, that the Property Trustee shall not
         be required to take any action unless it shall have obtained such
         legal opinions, if any, required by Sections 8.4(d) or 8.5(c), as the
         case may be, of this Agreement; and

                 (xi)     except as otherwise expressly provided by this
         Declaration, the Property Trustee shall not be under any obligation to
         take any action that is discretionary under the provisions of this
         Declaration.

                 In the event that the Trustee is also acting as authenticating
         agent, Paying Agent, transfer agent and security registrar, the rights
         and protections afforded to the Trustee pursuant to this Article III
         shall also be afforded to such authenticating agent, Paying Agent,
         transfer agent and security registrar.

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

SECTION 3.11     Delaware Trustee.

         Notwithstanding any provision of this Declaration other than Section
6.2, the Delaware Trustee shall not be entitled to exercise any powers, nor
shall the Delaware Trustee have any of the duties and responsibilities of the
Regular Trustees or the Property Trustee described in this Declaration.  Except
as set forth in Section 6.2, the Delaware Trustee shall be a Trustee for the
sole and limited purpose of fulfilling the requirements of Section 3807 of the
Business Trust Act. In no event shall the Property Trustee or the Delaware
Trustee be liable for any act or omission of any of the Regular Trustees
hereunder.

SECTION 3.12     Execution of Documents.

         Unless otherwise determined by the Regular Trustees, and except as
otherwise required by the Business Trust Act, any Regular Trustee is authorized
to execute on behalf of the Trust any documents that the Regular Trustees have
the power and authority to cause the Trust to execute pursuant to Section 3.6.

SECTION 3.13     Not Responsible for Recitals or Issuance of Trust Securities.

         The recitals contained in this Declaration and the Trust Securities
shall be taken as the statements of the Sponsor, and the Trustees do not assume
any responsibility for their correctness.  The Trustees make no representations
as to the value or condition of the property of the Trust or any part thereof.
The Trustees make no representations as to the validity or sufficiency of this
Declaration or the Trust Securities.

SECTION 3.14     Duration of Trust.

         The Trust, unless terminated pursuant to the provisions of Article
VIII hereof, shall have perpetual existence.

SECTION 3.15     Mergers.

         (a)     The Trust may not consolidate, amalgamate, merge with or into,
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except as
described in Section 3.15(b) and (c).





                                       18
<PAGE>   24
         (b)     The Trust may, with the consent of the Regular Trustees or, if
there are more than two, a majority of the Regular Trustees and without the
consent of the Holders of the Trust 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 of the United States;
provided that:

                 (i)      if the Trust is not the survivor, such successor
entity (the "Successor Entity") either:

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

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

                 (ii)     the Company expressly acknowledges a trustee of the
         Successor Entity that possesses the same powers and duties as the
         Property Trustee as the Holder of the Partnership Preferred
         Securities;

                 (iii)    the Trust Preferred Securities or any Successor Trust
         Securities are listed, or any Successor Trust Securities will be
         listed upon notification of issuance, on any national securities
         exchange or with another organization on which the Trust Preferred
         Securities are then listed or quoted;

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

                 (v)      such merger, consolidation, amalgamation or
         replacement does not adversely affect the rights, preferences and
         privileges of the Holders of the Trust Preferred Securities (including
         any Successor Trust Securities) in any material respect;

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

                 (vii)    the Company guarantees the obligations of such
         Successor Entity under the Successor Trust Securities at least to the
         extent provided by the Trust Guarantees; and

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

                          (A)     such merger, consolidation, amalgamation or
                 replacement will not adversely affect the rights, preferences
                 and privileges of the Holders of the Trust Preferred
                 Securities (including any Successor Trust 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 under the 1940 Act;

                          (C)     following such merger, consolidation,
                 amalgamation or replacement, the Trust (or the Successor
                 Entity) will not be classified as an association or a publicly
                 traded partnership taxable as a corporation for United States
                 federal income tax purposes; and

<PAGE>   25
                          (D)     following such merger, consolidation,
                 amalgamation or replacement, the Partnership will not be
                 classified as an association or a publicly traded partnership
                 taxable as a corporation for United States federal income tax
                 purposes.

         (c)     Notwithstanding Section 3.15(b), the Trust shall not, except
with the consent of Holders of 100% in liquidation amount of the Trust
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 an association or a publicly traded partnership taxable as
a corporation for United States federal income tax purposes.

         (e)     To negotiate the terms of an underwriting agreement and any
pricing agreement providing for the sale of the Trust Preferred Securities.

SECTION 4.2      Indemnification and Expenses of the Trustee

         The Partnership agrees, and to the extent the Partnership fails to do
so, the Sponsor agrees to indemnify the Property Trustee and the Delaware
Trustee and their respective officers, directors, employees and agents for, and
to hold each of them harmless against, any loss, liability or expense incurred
without negligence or bad faith on the part of the Property Trustee or the
Delaware Trustee, as the case may be, arising out of or in connection with the

except as permitted by this Declaration, (iii) to use its commercially
reasonable efforts to ensure that the Trust will not be an investment company

income tax purposes.

         (b)     After the issuance of any Trust Securities, the number of
Trustees may be increased or decreased by vote of the Holders of a Majority in
liquidation amount of the Trust Common Securities voting as a class at a
meeting of the Holders of the Trust Common Securities; provided, however, that
the number of Trustees shall in no event be less than three (3); provided

place of business in the State of Delaware, and otherwise meets the
requirements of applicable law,

provided that, if the Property Trustee has its principal place of business in
the State of Delaware and otherwise meets the requirements of applicable law,

documents which the Regular Trustees have the power and authority to cause the

         possessing the qualifications to act as Property Trustee under Section
         6.3 (a "Successor Property Trustee") has been appointed and has
         accepted such appointment by written instrument executed by such
         Successor Property Trustee and delivered to the Regular Trustees and
         the Sponsor;

                 (ii)     the Trustee that acts as Delaware Trustee shall not
         be removed in accordance with Section 6.7(a) until a successor Trustee
         possessing the qualifications to act as Delaware Trustee under
         Sections 6.2 and 6.4 (a "Successor Delaware Trustee") has been
         appointed and has accepted such appointment by written instrument
         executed by such Successor Delaware Trustee and delivered to the
         Regular Trustees and the Sponsor;

                 (iii)    no such removal of the Property Trustee or the
         Delaware Trustee shall be effective until all of the fees, charges,
         and expenses such entity have been paid.

         (c)     A Trustee appointed to office shall hold office until his
successor shall have been appointed or until his death, removal or resignation.

                 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 Trust Securities; and

                 (ii)     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





                                       23

         executed by such Successor Delaware Trustee and delivered to the
         Trust, the Sponsor and the resigning Delaware Trustee; and

                 (iii)    no such resignation of the Property Trustee or the

6.7 within 60 days after delivery to the Sponsor and the Trust of an instrument
of resignation, the resigning Property Trustee or Delaware Trustee, as
applicable, may petition any court of competent jurisdiction for appointment of
a Successor Property Trustee or Successor Delaware Trustee.  Such court may
thereupon, after prescribing such notice, if any, as it may deem proper and
prescribe, appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be.

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

SECTION 6.8      Vacancies among Trustees.

         If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 6.1, or if the number of Trustees
is increased pursuant to Section 6.1, a vacancy shall occur.  A resolution
certifying the existence of such vacancy by the Regular Trustees or, if there
are more than two, a majority of the Regular Trustees shall be conclusive
evidence of the existence of such vacancy.  The vacancy shall be filled with a
Trustee appointed in accordance with Section 6.7.

SECTION 6.9      Effect of Vacancies.

         The death, resignation, retirement, removal, bankruptcy, dissolution,
liquidation, incompetence or incapacity to perform the duties of a Trustee
shall not operate to 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 6.7, 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 6.10     Meetings.

         If there is more than one Regular Trustee, meetings of the Regular
Trustees shall be held from time to time upon the call of any Regular Trustee.
Regular meetings of the Regular Trustees may be held at a time and place fixed
by resolution of the Regular Trustees.  Notice of any in-person meetings of the
Regular Trustees shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than
48 hours before such meeting.  Notice of any telephonic meetings of the Regular
Trustees or any committee thereof shall be hand delivered or otherwise
delivered in writing (including by facsimile, with a hard copy by overnight
courier) not less than 24 hours before a meeting.  Notices shall contain a
brief statement of the time, place and anticipated purposes of the meeting.
The presence (whether in person or by telephone) of a Regular Trustee at a
meeting shall constitute a waiver of notice of such meeting except where a
Regular Trustee attends a meeting for the express purpose of objecting to the
transaction of any activity on the ground that the meeting has not been
lawfully called or convened.  Unless provided otherwise in this Declaration,
any action of the Regular Trustees may be taken at a meeting by vote of a
majority of the Regular Trustees present (whether in person or by telephone)
and eligible to vote with respect to such matter, provided that a Quorum is
present, or without a meeting





                                       24
<PAGE>   30
by the unanimous written consent of the Regular Trustees.  Notwithstanding the
foregoing, any and all actions of the Regular Trustees may be taken by the
unanimous written consent of all Regular Trustees.

SECTION 6.11     Delegation of Power.

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

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

SECTION 6.12     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 a party, 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.

                                  ARTICLE VII
                                 DISTRIBUTIONS

SECTION 7.1      Distributions.

         (a)     Holders of Trust Securities shall be entitled to receive
cumulative cash distributions at the rate per annum of 8.30% of the stated
liquidation amount of $25 per Trust Security, calculated on the basis of a
360-day year consisting of twelve 30-day months.  For any period shorter than a
full 90-day quarter, distributions will be computed on the basis of the actual
number of days elapsed in such 90-day quarter.  Distributions shall be made on
the Trust Preferred Securities and the Trust Common Securities on a Pro Rata
basis.  Distributions on the Trust Securities shall, from the date of original
issue, accrue and be cumulative and shall be payable quarterly only to the
extent that the Trust has funds available for the payment of such Distributions
in the Property Account.  Distributions not paid on the scheduled payment date
will accumulate and compound quarterly at the rate of 8.30% per annum
("Compounded Distributions").  "Distributions" shall mean ordinary cumulative
distributions in respect of each Fiscal Period together with any Compounded
Distributions.  If and to the extent that the Partnership makes a distribution
on the Partnership Preferred Securities held by the Property Trustee or the
Company makes a payment under the Partnership Guarantee (the amount of any such
partnership distribution, including any compounded partnership distributions,
or guarantee payment being a "Payment Amount"), the Trust shall and the
Property Trustee is directed, to the extent funds are available for that
purpose pursuant to Section 7.1(c), to make a Pro Rata Distribution of the
Payment Amount to Holders.

         (b)     Distributions on the Trust Securities will be cumulative, will
accrue from the date of initial issuance and will be payable quarterly in
arrears on each March 31, June 30, September 30 and December 31, commencing
December 31, 1996, when, as and if available for payment, by the Property
Trustee, except as otherwise described below.  If Distributions are not paid
when scheduled, the accrued Distributions shall be paid to the Holders of
record of Trust Securities as they appear on the books and records of the Trust
on the record date as determined under Section 7.1(d) below.





                                       25
<PAGE>   31
         (c)     Amounts available to the Trust for distribution to the Holders
of the Trust Securities will be limited to payments received by the Trust from
the Partnership on the Partnership Preferred Securities or from the Company on
the Partnership Guarantees paid by the Company to the Trust.  If the Property
Trustee, as the holder of the Partnership Preferred Securities for the benefit
of the Holders of the Trust Securities, receives written notice of any
determination by the Partnership not to pay distributions on such Partnership
Preferred Securities, the Property Trustee shall give notice of such
determination to the Holders.

         (d)     Distributions on the Trust Securities will be payable to the
Holders thereof as they appear on the books and records of the Trust on the
relevant record dates, which relevant record dates, as long as the Trust
Preferred Securities remain in book-entry only form, will be one Business Day
prior to the relevant payment dates.  Such distributions will be paid through
the Property Trustee who will hold amounts received in respect of the
Partnership Preferred Securities in the Property Account for the benefit of the
Holders of the Trust Securities.  In the event that the Trust Securities do not
remain in book-entry only form, the relevant record dates shall be the 15th day
of the month of the relevant payment dates.  In the event that any date on
which distributions are payable on the Trust Securities is not a Business Day,
payment of the distribution payable on such date will be made on the next
succeeding day which is a Business Day (without any interest or other payment
in respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day (without any reduction in interest or other payments in
respect of such early payment).

                                  ARTICLE VIII
                          ISSUANCE OF TRUST SECURITIES

SECTION 8.1      Designation and General Provisions Regarding Trust Securities.

         (a)     The Regular Trustees shall on behalf of the Trust issue one
class of preferred securities representing undivided beneficial ownership
interests in the assets of the Trust (the "Trust Preferred Securities") and one
class of common securities representing undivided beneficial ownership
interests in the assets of the Trust (the "Trust Common Securities") as
follows:

                 (i)      Trust Preferred Securities.  8,000,000 Trust
         Preferred Securities of the Trust with an aggregate liquidation amount
         with respect to the assets of the Trust of two hundred million dollars
         ($200,000,000) and a liquidation amount with respect to the assets of
         the Trust of $25 per preferred security, are hereby designated for the
         purpose of identification only as 8.30% Trust Originated Preferred
         SecuritiesSM (the "Trust Preferred Securities").  The Trust Preferred
         Security Certificates evidencing the Trust Preferred Securities shall
         be substantially in the form of Exhibit A-1 to the Declaration, with
         such changes and additions thereto or deletions therefrom as may be
         required by ordinary usage, custom or practice or to conform to the
         rules of any stock exchange on which the Trust Preferred Securities
         are listed.

                 (ii)     Trust Common Securities.  247,440 Trust Common
         Securities of the Trust with an aggregate liquidation amount with
         respect to the assets of the Trust of six million one hundred eighty
         six thousand dollars ($6,186,000) 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 8.30%
         Trust Common Securities (the "Trust Common Securities" and, together
         with the Trust Preferred Securities, the "Trust Securities").  The
         Trust Common Security Certificates evidencing the Trust Common
         Securities shall be substantially in the form of Exhibit A-2 to the
         Declaration, with such changes and additions thereto or deletions
         therefrom as may be required by ordinary usage, custom or practice.

         (b)     Except as provided in Section 9.2(b) of this Declaration, the
Trust Preferred Securities rank pari passu and payment thereon shall be made
Pro Rata with the Trust Common Securities.  The Trust shall issue no securities
or other interests in the assets of the Trust other than the Trust Preferred
Securities and the Trust Common Securities.





                                       26
<PAGE>   32
         (c)     Any Regular Trustee shall sign the Trust Securities for the
Trust by manual or facsimile signature.  In case any Regular Trustee of the
Trust who shall have signed any of the Trust Securities shall cease to be a
Regular Trustee before the Certificates so signed shall be delivered by the
Trust, such Certificates nevertheless may be delivered as though the person who
signed such Certificates had not ceased to be such Regular Trustee; and any
Certificate may be signed on behalf of the Trust by such persons who, at the
actual date of execution of such Trust Security, shall be the Regular Trustees
of the Trust, although at the date of the execution and delivery of the
Declaration any such person was not such a Regular Trustee.  Certificates shall
be printed, lithographed or engraved or may be produced in any other manner as
is reasonably acceptable to the Regular Trustees, as evidenced by their
execution thereof, and may have such 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 Trust Securities may
be listed, or to conform to usage.

         A Trust Security shall not be valid until authenticated by the manual
signature of an authorized officer of the Property Trustee.  Such signature
shall be conclusive evidence that the Trust Security has been authenticated
under this Declaration.

         Upon a written order of the Trust, signed by at least one Regular
Trustee, directing the Property Trustee to authenticate and deliver Trust
Securities, the Property Trustee shall authenticate and deliver the Trust
Securities for original issue.  The aggregate number of Trust Securities
outstanding at any time shall not exceed the number set forth in the Terms of
the Trust Securities.

         The Property Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Trust Securities.  An authenticating agent may
authenticate Trust 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 Sponsor or an Affiliate of
the Sponsor.

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

         (e)     Upon issuance of the Trust Securities as provided in this
Declaration, the Trust Securities so issued shall be deemed to be validly
issued, fully paid and non-assessable, subject to Section 11.1 with respect to
the Trust Common Securities.

         (f)     Every Person, by virtue of having become a Holder or a Trust
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.

SECTION 8.2      Redemption of Trust Securities.

         (a)     Upon a purchase of the Partnership Preferred Securities by the
Partnership upon redemption or otherwise, the proceeds from such purchase shall
be simultaneously applied Pro Rata to redeem Trust Securities having an
aggregate liquidation amount equal to the Partnership Preferred Securities so
purchased or redeemed for an amount equal to $25 per Trust Security plus an
amount equal to accrued and unpaid Distributions, including any Compounded
Distributions thereon through the date of the redemption or such lesser amount
as shall be received by the Trust in respect of the Partnership Preferred
Securities so purchased or redeemed  as calculated by the Regular Trustees (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 Trust Securities are to be
so redeemed, the Trust Common Securities and the Trust Preferred Securities
will be redeemed Pro Rata and the Trust Preferred Securities to be redeemed
will be redeemed as described in Section 8.3 below.





                                       27
<PAGE>   33
         (c)     If, at any time, a Trust Special Event shall occur and be
continuing, the Regular Trustees shall, unless the Partnership Preferred
Securities are redeemed in the limited circumstances described below, within 90
days following the occurrence of such Trust Special Event elect to either (i)
dissolve the Trust upon not less than 30 nor more than 60 days' notice with the
result that, after satisfaction of creditors, if any, of the Trust, Partnership
Preferred Securities with an aggregate principal amount equal to the aggregate
stated liquidation amount of, with a distribution rate identical to the
distribution rate of, and accrued and unpaid distributions equal to accrued and
unpaid distributions on, and having the same record date for payment as, the
Trust Preferred Securities and the Trust Common Securities outstanding at such
time would be distributed on a Pro Rata basis to the Holders of the Trust
Preferred Securities and the Trust Common Securities in liquidation of such
Holders' interests in the Trust; provided, however, that if at the time there
is available to the Trust the opportunity to eliminate, within such 90-day
period, the Trust Special Event by taking some ministerial action, such as
filing a form or making an election, or pursuing some other similar reasonable
measure which in the sole judgment of the Sponsor has or will cause no adverse
effect on the Trust, the Partnership, the Sponsor or the Holders of the Trust
Securities and will involve no material cost, the Trust will pursue such
measure in lieu of dissolution or (ii) cause the Trust Preferred Securities to
remain outstanding, provided that in the case of this clause (ii), the Sponsor
shall pay any and all expenses incurred by or payable by the Trust attributable
to the Trust Special Event.  Furthermore, if in the case of the occurrence of a
Trust Tax Event, the Regular Trustees have received a Trust Redemption Tax
Opinion, then the General Partner shall have the right, within 90 days
following the occurrence of such Trust Tax Event, to elect to cause the
Partnership to redeem the Partnership Preferred Securities in whole (but not in
part) for cash upon not less than 30 nor more than 60 days' notice and promptly
following such redemption, the Trust Securities will be redeemed by the Trust
at the Redemption Price.

         (d)     If the Partnership Preferred Securities are distributed to the
Holders of the Trust Preferred Securities, the Sponsor will use its best
efforts to cause the Partnership Preferred Securities to be listed on the New
York Stock Exchange or on such other national securities exchange or similar
organization as the Trust Preferred Securities are then listed or quoted.

         (e)     On the date fixed for any distribution of Partnership
Preferred Securities, upon dissolution of the Trust, (i) the Trust Preferred
Securities and the Trust Common Securities will no longer be deemed to be
outstanding and (ii) certificates representing Trust Securities will be deemed
to represent the Partnership Preferred Securities having an aggregate principal
amount equal to the stated liquidation amount of, and bearing accrued and
unpaid distributions equal to accrued and unpaid distributions on, such Trust
Securities until such certificates are presented to the Sponsor or its agent
for transfer or reissuance.

SECTION 8.3      Redemption Procedures.

         (a)     Notice of any redemption of, or notice of distribution of
Partnership Preferred Securities in exchange for, the Trust Securities (a
"Redemption/Distribution Notice") will be given by the Trust by mail to each
Holder of Trust 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 Partnership Preferred Securities.  For purposes of the calculation of the
date of redemption or exchange and the dates on which notices are given
pursuant to this Section 8.3, 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 Trust Securities.  Each Redemption/Distribution Notice
shall be addressed to the Holders of Trust 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.

         (b)     In the event that fewer than all the outstanding Trust
Securities are to be redeemed, the Trust Securities to be redeemed shall be
redeemed Pro Rata from each Holder of Trust Securities, provided that, in
respect of Trust Preferred Securities registered in the name of and held of
record by DTC or its nominee (or any successor Clearing Agency or its nominee)
or any nominee, the distribution of the proceeds of such redemption





                                       28
<PAGE>   34
will be made to each Clearing Agency Participant (or Person on whose behalf
such nominee holds such securities) in accordance with the procedures applied
by such agency or nominee.

         (c)     If Trust Securities are to be redeemed and the Trust gives a
Redemption/Distribution Notice, which notice may only be issued if the
Partnership Preferred Securities are redeemed as set out in this Section 8.3
(which notice will be irrevocable), then (A) while the Trust Preferred
Securities are in book-entry only form, by 12:00 noon, New York City time, on
the redemption date, the Property Trustee will deposit irrevocably with the DTC
or its nominee (or successor Clearing Agency or its nominee) funds sufficient
to pay the applicable Redemption Price with respect to the Trust Preferred
Securities and will give the DTC irrevocable instructions and authority to pay
the Redemption Price to the Holders of the Trust Preferred Securities, and (B)
with respect to Trust Preferred Securities issued in definitive form and Trust
Common Securities, the Property Trustee will pay the relevant Redemption Price
to the Holders of such Trust 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 Trust Securities so
called for redemption and all rights of Holders of such Trust Securities will
cease, except the right of the Holders of such Trust Securities to receive the
Redemption Price, but without interest on such Redemption Price.  If any date
fixed for redemption of Trust 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 (without any reduction in interest or other payments in respect of such
early payment).  If payment of the Redemption Price in respect of any Trust
Securities is improperly withheld or refused and not paid either by the
Property Trustee or by the Sponsor as guarantor pursuant to the relevant Trust
Guarantee, Distributions on such Trust Securities will continue to accrue at
the then applicable rate from the original redemption date to the actual date
of payment, in which case the actual payment date will be considered the date
fixed for redemption for purposes of calculating the Redemption Price.  For
these purposes, the applicable Redemption Price shall not include Distributions
which are being paid to Holders who were Holders on a relevant record date.
Upon satisfaction of the foregoing conditions, then immediately prior to the
close of business on the date of such deposit or payment, all rights of Holders
of such Trust Preferred Securities so called for redemption will cease, except
the right of the Holders to receive the Redemption Price, but without interest
on such Redemption Price, and from and after the date fixed for redemption,
such Trust Preferred Securities will not accrue distributions or bear interest.

         Neither the Regular Trustees nor the Trust shall be required to
register or cause to be registered the transfer of any Trust Securities that
have been called for redemption.

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

SECTION 8.4      Voting Rights of Trust Preferred Securities.

         (a)     Except as provided under Sections 2.6,  6.1(b) and this
Article VIII and as otherwise required by the Business Trust Act, the Trust
Indenture Act and other applicable law, the Holders of the Trust Preferred
Securities will have no voting rights.

         (b)     Subject to the requirement of the Property Trustee obtaining a
tax opinion in certain circumstances set forth in Section 8.4(d) below, the
Holders of a Majority in liquidation amount of the Trust Preferred Securities
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or direct the
exercise of any trust or power conferred upon the Property Trustee under the
Declaration, including the right to direct the Property Trustee, as Holder of
the Partnership Preferred Securities, to (i) exercise the remedies available to
it under the Limited Partnership Agreement as a Holder of the Partnership
Preferred Securities, including the right to direct the Special Representative
of the Partnership as elected by the





                                       29
<PAGE>   35
Holders of the Partnership Preferred Securities in accordance with the Limited
Partnership Agreement (A) to enforce the Partnership's creditors rights and
other rights with respect to the Affiliate Investment Instruments and any
Investment Guarantees, (B) to enforce the rights of the Holders of the
Partnership Preferred Securities under the Partnership Guarantee, and (C) to
enforce the rights of the Holders of the Partnership Preferred Securities to
receive distributions (if and to the extent such distributions have been
declared out of funds legally available therefor by the General Partner in its
sole discretion) on the Partnership Preferred Securities or (ii) consent to any
amendment, modification, or termination of the Limited Partnership Agreement or
the Partnership Preferred Securities where such consent shall be required;
provided, however, that where a consent or action under the Limited Partnership
Agreement would require the consent or act of the Holders of more than a
majority of the aggregate liquidation amount of Partnership Preferred
Securities affected thereby, only the Holders of the percentage of the
aggregate stated liquidation amount of the Trust Preferred Securities which is
at least equal to the percentage required under the Limited Partnership
Agreement may direct the Property Trustee to give such consent or take such
action.

         (c)     If the Property Trustee fails to enforce its rights under the
Partnership Preferred Securities after a Holder of record of Trust Preferred
Securities has made a written request, such Holder of record of Trust Preferred
Securities may institute a legal proceeding directly against the General
Partner or the Special Representative, to enforce the Property Trustee's rights
under the Limited Partnership Agreement without first instituting any legal
proceeding against the Property Trustee or any other person or entity.
Notwithstanding the foregoing, if a Trust Enforcement Event has occurred and is
continuing and such event is attributable to the failure of an Investment
Affiliate to make any required payment when due on any Affiliate Investment
Instrument, then a Holder of Trust Preferred Securities may directly institute
a proceeding against such Investment Affiliate for enforcement of payment with
respect to such Affiliate Investment Instrument.

         (d)     The Property Trustee shall notify all Holders of the Trust
Preferred Securities of any notice of any Partnership Enforcement Event
received from the General Partner with respect to the Partnership Preferred
Securities and the Affiliate Investment Instruments.  Such notice shall state
that such Partnership Enforcement Event also constitutes a Trust Enforcement
Event.  Except with respect to directing the time, method, and place of
conducting a proceeding for a remedy, the Property Trustee shall be under no
obligation to take any of the actions described in clause 8.4(b)(i) and (ii)
above unless the Property Trustee has obtained an opinion of independent tax
counsel to the effect that as a result of such action, the Trust will not be
classified as an association or a publicly traded partnership taxable as a
corporation for United States federal income tax purposes and each Holder will
be treated as owning an undivided beneficial ownership interest in the
Partnership Preferred Securities.

         (e)     In the event the consent of the Property Trustee, as the
Holder of the Partnership Preferred Securities, is required under the Limited
Partnership Agreement with respect to any amendment, modification or
termination of the Limited Partnership Agreement, the Property Trustee shall
request the direction of the Holders of the Trust 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 Trust Securities voting together as a single class; provided,
however, that where a consent under the Limited Partnership Agreement would
require the consent of the Holders of more than a majority of the aggregate
principal amount of the Partnership Preferred Securities, the Property Trustee
may only give such consent at the direction of the Holders of at least the same
proportion in aggregate stated liquidation amount of the Trust Securities.  The
Property Trustee shall not take any such action in accordance with the
directions of the Holders of the Trust Securities unless the Property Trustee
has obtained an opinion of tax counsel to the effect that as a result of such
action, the Trust will not be classified as an association or a publicly traded
partnership taxable as a corporation for United States federal income tax
purposes.

         (f)     A waiver of a Partnership Enforcement Event with respect to
the Partnership Preferred Securities will constitute a waiver of the
corresponding Trust Enforcement Event.

         (g)     Any required approval or direction of Holders of Trust
Preferred Securities may be given at a separate meeting of Holders of Trust
Preferred Securities convened for such purpose, at a meeting of all of the





                                       30
<PAGE>   36
Holders of Trust Securities or pursuant to written consent.  The Regular
Trustees will cause a notice of any meeting at which Holders of Trust 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 Trust Preferred Securities.  Each such notice will include a statement
setting forth the following information:  (i) the date of such meeting or the
date by which such action is to be taken; (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to
vote or of such matter upon which written consent is sought; and (iii)
instructions for the delivery of proxies or consents.

         (h)     No vote or consent of the Holders of Trust Preferred
Securities will be required for the Trust to redeem and cancel Trust Preferred
Securities or distribute Partnership Preferred Securities in accordance with
the Declaration.

         (i)     Notwithstanding that Holders of Trust Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Trust Securities that are owned at such time by the Company or any
entity directly or indirectly controlled by, or under direct or indirect common
control with, the Company, shall not be entitled to vote or consent and shall,
for purposes of such vote or consent, be treated as if such Trust Securities
were not outstanding, provided, however that persons otherwise eligible to vote
to whom the Company or any of its subsidiaries have pledged Trust Preferred
Securities may vote or consent with respect to such pledged Trust Preferred
Securities under any of the circumstances described herein.

         (j)     Holders of the Trust Preferred Securities will have no rights
to appoint or remove the Regular Trustees, who may be appointed, removed or
replaced solely by the Company, as the Holder of all of the Trust Common
Securities.

SECTION 8.5      Voting Rights of Trust Common Securities.

         (a)     Except as provided under this Section 8.5 or as otherwise
required by the Business Trust Act, the Trust Indenture Act or other applicable
law or provided by the Declaration, the Holders of the Trust Common Securities
will have no voting rights.

         (b)     The Holders of the Trust Common Securities are entitled,
subject to Article VI hereof, 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
Trust Enforcement Events with respect to the Trust Preferred Securities have
been cured, waived, or otherwise eliminated and subject to the requirement of
the Property Trustee obtaining a tax opinion in certain circumstances set forth
in this paragraph (c), the Holders of a Majority in liquidation amount of the
Trust Common Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Property Trustee, or
direct the exercise of any trust or power conferred upon the Property Trustee
under the Declaration, including the right to direct the Property Trustee, as
Holder of the Partnership Preferred Securities, to (i) exercise the remedies
available to it under the Limited Partnership Agreement as a Holder of the
Partnership Preferred Securities, including the right to direct the Special
Representative of the Partnership as elected by the Holders of the Partnership
Preferred Securities in accordance with the Limited Partnership Agreement (A)
to enforce the Partnership's creditors rights and other rights with respect to
the Affiliate Investment Instruments and any Investment Guarantees, (B) to
enforce the rights of the Holders of the Partnership Preferred Securities under
the Partnership Guarantee, and (C) to enforce the rights of the Holders of the
Partnership Preferred Securities to receive distributions (if and to the extent
such distributions have been declared out of funds legally available therefor
by the General Partner in its sole discretion) on the Partnership Preferred
Securities or (ii) consent to any amendment, modification, or termination of
the Limited Partnership Agreement or the Partnership Preferred Securities where
such consent shall be required; provided, however, that where a consent or
action under the Limited Partnership Agreement would require the consent or act
of the Holders of more than a majority of the aggregate liquidation amount of
Partnership Preferred Securities affected thereby, only the Holders of the
percentage of the aggregate stated liquidation amount of the Trust Common
Securities which is at least equal to the percentage required under the Limited
Partnership Agreement





                                       31
<PAGE>   37
may direct the Property Trustee to give such consent or take such action.
Except with respect to directing the time, method, and place of conducting a
proceeding for a remedy, the Property Trustee shall be under no obligation to
take any of the actions described in clause 8.5(c)(i) and (ii) above unless the
Property Trustee has obtained an opinion of independent tax counsel to the
effect that, as a result of such action, for United States federal income tax
purposes the Trust will not be classified as an association or a publicly
traded partnership taxable as a corporation.

         (d)     If the Property Trustee fails to enforce its rights under the
Partnership Preferred Securities after a Holder of record of Trust Common
Securities has made a written request, such Holder of record of Trust Common
Securities may directly institute a legal proceeding directly against the
Company, as General Partner of the Partnership or the Special Representative,
to enforce the Property Trustee's rights under the Partnership Preferred
Securities without first instituting any legal proceeding against the Property
Trustee or any other person or entity.  Notwithstanding the foregoing, if a
Trust Enforcement Event has occurred and is continuing and such event is
attributable to the failure of an Investment Affiliate to make any required
payment when due on any Affiliate Investment Instrument, then a Holder of Trust
Common Securities may directly institute a proceeding against such Investment
Affiliate for enforcement of payment with respect to such Affiliate Investment
Instrument.

         (e)     A waiver of a Partnership Enforcement Event with respect to
the Partnership Preferred Securities will constitute a waiver of the
corresponding Trust Enforcement Event.

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

         (g)     No vote or consent of the Holders of the Trust Common
Securities shall be required for the Trust to redeem and cancel Trust Common
Securities or to distribute Partnership Preferred Securities in accordance with
the Declaration and the terms of the Trust Securities.

SECTION 8.6      Paying Agent.

         In the event that the Trust Preferred Securities are not in book-entry
only form, the Trust shall maintain in the Borough of Manhattan, City of New
York, State of New York, an office or agency where the Trust Preferred
Securities may be presented for payment ("Paying Agent).  The Trust may appoint
the Paying Agent and may appoint one or more additional paying agents in such
other locations as it shall determine.  The term "Paying Agent" includes any
additional paying agent.  The Trust may change any Paying Agent without prior
notice to any Holder.  The Trust shall notify the Property Trustee of the name
and address of any Paying Agent not a party to this Declaration.  If the Trust
fails to appoint or maintain another entity as Paying Agent, the Property
Trustee shall act as such.  The Trust or any of its Affiliates may act as
Paying Agent.  The Chase Manhattan Bank shall initially act as Paying Agent for
the Trust Preferred Securities and the Trust Common Securities.

SECTION 8.7      Listing

         The Sponsor shall use its best efforts to cause the Trust Preferred
Securities to be listed for quotation on the New York Stock Exchange.

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

                                   ARTICLE IX

SECTION 9.1      Termination of Trust.

         (a)     The Trust shall terminate:

                 (i)      upon the bankruptcy, insolvency or dissolution of the
         Holder of Trust Common Securities or the Sponsor;

                 (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 after having
         obtained the consent of at least a Majority in liquidation amount of
         the Trust Securities, voting together as a single class, to file such
         certificate of cancellation, or the revocation of the Sponsor's
         charter 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;

                 (iv)     when all of the Trust 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 Trust Securities;

                 (v)      upon the election of the Regular Trustees, following
         the occurrence and continuation of a Trust Special Event, pursuant to
         which the Trust shall have been dissolved in accordance with the terms
         of the Trust Securities and all of the Partnership Preferred
         Securities shall have been distributed to the Holders of Trust
         Securities in exchange for all of the Trust Securities; or

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

         (b)     As soon as is practicable after the occurrence of an event
referred to in Section 9.1(a), the Trustees shall file a certificate of
cancellation with the Secretary of State of the State of Delaware.

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

SECTION 9.2      Liquidation Distribution Upon Termination and Dissolution of
                 the Trust.

         (a)     In the event of any voluntary or involuntary liquidation,
dissolution, winding-up or termination of the Trust (each a "Trust
Liquidation"), the Holders of the Trust Preferred Securities on the date of the
Trust Liquidation will be entitled to receive, out of the assets of the Trust
available for distribution to Holders of Trust Securities after satisfaction of
the Trusts' liabilities and creditors, distributions in cash or other
immediately available funds in an amount equal to the aggregate of the stated
liquidation amount of $25 per Trust Security plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the "Trust
Liquidation Distribution"), unless, in connection with such Trust Liquidation,
Partnership Preferred Securities in an aggregate stated liquidation amount
equal to the aggregate stated liquidation amount of, with a distribution rate
identical to the distribution rate of, and accrued and unpaid distributions
equal to accrued and unpaid distributions on, such Trust Securities shall be
distributed on a Pro Rata basis to the Holders of the Trust Securities in
exchange for such Trust Securities.





                                       33
<PAGE>   39
         (b)     If, upon any such Trust Liquidation, the Trust Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Trust Liquidation Distribution, then,
except as provided below, the amounts payable directly by the Trust on the
Trust Securities shall be paid on a Pro Rata basis.  The Holders of the Trust
Common Securities will be entitled to receive distributions upon any such Trust
Liquidation Pro Rata with the Holders of the Trust Preferred Securities except
that if the Company is in default on any of its obligations under the Trust
Preferred Securities Guarantee, the Partnership Guarantee, or any Investment
Guarantee, or any Investment Event of Default has occurred and is continuing
with respect to an Affiliate Investment Instrument, the Trust Preferred
Securities shall have a preference over the Trust Common Securities with regard
to such distributions as provided below.  Such preference is effectuated by the
Holder of the Trust Common Securities hereby agreeing to provide limited
recourse guarantees as follows:  (i) to the Holders of the Trust Preferred
Securities, of the Company's obligations under the Trust Preferred Securities
Guarantee; (ii) to the Trust and the Holders of the Trust Preferred Securities,
of the Company's obligations under the Partnership Guarantee; and (iii) to the
Partnership and the Holders of the Trust Preferred Securities, of the Company's
obligations under any Investment Guarantee and/or the obligations of any
Investment Affiliate under an Affiliate Investment Instrument.  In the case of
the limited recourse guarantee given by the Holder of the Trust Common
Securities to the Partnership and the Holder of the Trust Preferred Securities
in respect of the Company's obligations under any Investment Guarantee and/or
any Investment Affiliate's obligations under an Affiliate Investment
Instrument, (i) the Trust Common Securities Holder will be deemed to have
pledged the amount due in respect of its Trust Common Securities upon a
liquidation of the Trust to the Partnership and the Holders of Trust Preferred
Securities; (ii) the Trust Common Securities Holder will be deemed to have paid
such amount to the Partnership in respect of such defaulted Investment
Guarantee and/or Affiliate Investment Instrument, as the case may be; (iii) the
Partnership will be deemed to have paid such amount to the Trust; and (iv) the
Property Trustee is hereby authorized to distribute such amount to the Holders
of Trust Preferred Securities (on a pro rata basis among such Trust Preferred
Securities Holders) in respect of the Trust Common Securities Holder's pledge
of such amounts to such Trust Preferred Securities Holders.  In the case of a
limited recourse guarantee given by the Holder of the Trust Common Securities
to the Trust and the Holders of the Trust Preferred Securities in respect of
the Company's obligations under the Partnership Guarantee, (i) the Holder of
the Trust Common Securities will be deemed to have pledged the amount due in
respect of its Trust Common Securities upon a liquidation of the Trust to the
Trust and the Holders of the Trust Preferred Securities; (ii) the Holder of the
Trust Common Securities will be deemed to have paid such amount to the Trust in
respect of its obligations under the Partnership Guarantee; and (iii) the
Property Trustee is hereby authorized to distribute such amount to the Holders
of the Trust Preferred Securities (on a pro rata basis among such Trust
Preferred Securities Holders) in respect of the Trust Common Securities
Holder's pledge of such amount to such Trust Preferred Securities Holders.

SECTION 10.1     Transfer of Trust Securities.

         (a)     Trust Securities may only be transferred, in whole or in part,

freely transferable.

SECTION 10.2     Transfer of Certificates.

         The Regular Trustees shall provide for the registration of

charge but only upon payment (with such indemnity as the Regular Trustees may
require) in respect of any tax or other government charges that may be imposed
in relation to it.  Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to
be issued in the name of the designated transferee or transferees.  Every
Certificate surrendered for registration of





                                       34
<PAGE>   40
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 be subject to
the obligations of a Holder hereunder upon the receipt by such transferee of a
Certificate.  By acceptance of a Certificate, each transferee shall be deemed
to have agreed to be bound by this Declaration.

SECTION 10.3     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 Trust 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 Trust Securities represented by such
Certificate on the part of any Person, whether or not the Trust shall have
actual or other notice thereof.

SECTION 10.4     Book-Entry Interests.

         Unless otherwise specified in the terms of the Trust Preferred
Securities, the Trust Preferred Securities Certificates, on original issuance,
will be issued in the form of one or more fully registered, global Trust
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 Trust Preferred
Security Beneficial Owner will receive a definitive Trust Preferred Security
Certificate representing such Trust Preferred Security Beneficial Owner's
interests in such Global Certificates, except as provided in Section 10.7.
Unless and until definitive, fully registered Trust Preferred Security
Certificates (the "Definitive Trust Preferred Security Certificates") have been
issued to the Trust Preferred Security Beneficial Owners pursuant to Section
10.7:

         (a)     the provisions of this Section 10.4 shall be in full force and
effect;

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

         (c)     to the extent that the provisions of this Section 10.4
conflict with any other provisions of this Declaration, the provisions of this
Section 10.4 shall control; and

         (d)     the rights of the Trust Preferred Security Beneficial Owners
shall be exercised only through the Clearing Agency and shall be limited to
those established by law and agreements between such Trust Preferred Security
Beneficial Owners and the Clearing Agency and/or the Clearing Agency
Participants and the Clearing Agency shall receive and transmit payments of
Distributions on the Global Certificates to such Clearing Agency Participants.
The Clearing Agency 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 Trust Preferred Securities have voted on any
matter provided for in this Declaration, so long as Definitive Trust Preferred
Security Certificates have not been issued, the Trustees may conclusively rely
on, and shall be fully  protected in relying on, any written instrument
(including a proxy) delivered to the Trustees by the Clearing Agency setting
forth the Trust Preferred Security Beneficial Owners' votes or assigning the
right to vote on any matter to any other Persons either in whole or in part.

SECTION 10.5     Notices to Clearing Agency.

         Whenever a notice or other communication to the Trust Preferred
Security Holders is required under this Declaration, unless and until
Definitive Trust Preferred Security Certificates shall have been issued to the
Trust Preferred Security Beneficial Owners pursuant to Section 10.7, the
Regular Trustees shall give all such notices and communications specified
herein to be given to the Trust Preferred Security Holders to the Clearing
Agency, and shall have no notice obligations to the Trust Preferred Security
Beneficial Owners.

SECTION 10.6     Appointment of Successor Clearing Agency.

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

SECTION 10.7     Definitive Trust Preferred Security Certificates.

         If (a) a Clearing Agency elects to discontinue its services as
securities depositary with respect to the Trust Preferred Securities and a
successor Clearing Agency is not appointed within 90 days after such
discontinuance pursuant to Section 10.6;  (b) the Regular Trustees elect after
consultation with the Sponsor to terminate the book-entry system through the
Clearing Agency with respect to the Trust Preferred Securities; or (c) there is
a Trust Enforcement Event (to the extent required by the Clearing Agency),
then:

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

                 (ii)     upon surrender of the Global Certificates by the
         Clearing Agency, accompanied by registration instructions, the Regular
         Trustees shall cause Definitive Trust Preferred Security Certificates
         to be delivered to Trust Preferred Security Beneficial Owners in
         accordance with the instructions of the Clearing Agency.  Neither the
         Trustees nor the Trust shall be liable for any delay in delivery of
         such instructions and each of them may conclusively rely on and shall
         be protected in relying on, said instructions of the Clearing Agency.
         The Definitive Trust 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
         Trust Preferred Securities may be listed, or to conform to usage.

SECTION 10.8     Mutilated, Destroyed, Lost or Stolen Certificates.

         If (a) any mutilated Certificates should be surrendered to the Regular
Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and (b)
there shall be delivered to the Regular Trustees such security or indemnity as
may be required by them to keep each of them harmless, then, in the absence of
notice that such Certificate shall have been acquired by a bona fide purchaser,
any Regular Trustee on behalf of the Trust shall execute and deliver, in
exchange for 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 10.8, the Regular Trustees
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith.  Any duplicate
Certificate issued pursuant to this Section shall constitute conclusive
evidence of an ownership interest in the relevant Trust Securities, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

                           LIMITATION OF LIABILITY OF
                HOLDERS OF TRUST SECURITIES, TRUSTEES OR OTHERS

SECTION 11.1     Liability.

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

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

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

         (b)     Notwithstanding any other provision herein, the Holder of the
Trust Common Securities, by entering into this Agreement, agrees that it shall
be liable directly to any creditor or claimant of or against the Trust for the
entire amount of all of the debts and obligations of the Trust (other than
obligations to the Holders of Trust Securities in their capacities as Holders)
to the extent not satisfied out of the Trust's assets as if the Holder of the
Trust Common Securities were the General Partner of a limited partnership
organized under the Delaware Revised Uniform Limited Partnership Act.  This
Section 11.1(b) will automatically terminate upon (i) the adoption of final or
temporary United States federal tax regulations which, if the Trust were not
classified as a grantor trust for United States federal income tax purposes,
would result in the classification of the Trust as a partnership for United
States federal tax purposes without regard to its organic characteristics and
(ii) the taking of such action, if any, by the Trust or the Holders of Trust
Securities as may be necessary to achieve such classification.

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

SECTION 11.2     Exculpation.

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

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

SECTION 11.3     Fiduciary Duty.

         (a)     To the extent that, at law or in equity, an Indemnified Person
has duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for
its good faith reliance on the provisions of this Declaration.  The provisions
of this Declaration, to the extent that they restrict the duties and





                                       37
<PAGE>   43
liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Property Trustee under the Trust
Indenture Act), are agreed by the parties hereto to replace such other duties
and liabilities of such Indemnified Person.

         (b)     Unless otherwise expressly provided herein:

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

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

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

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

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

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

SECTION 11.4     Indemnification.

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

                 (ii)     The Sponsor shall indemnify, to the fullest extent
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action or suit by or in the right of the Trust to procure a
         judgment in its favor by reason of the fact that he is or was a
         Company Indemnified Person against expenses (including attorneys'
         fees) actually and reasonably incurred by him in connection with the
         defense or settlement of such action or





                                       38
<PAGE>   44
         suit if he acted in good faith and in a manner he reasonably believed
         to be in or not opposed to the best interests of the Trust and except
         that no such indemnification shall be made in respect of any claim,
         issue or matter as to which such Company Indemnified Person shall have
         been adjudged to be liable to the Trust unless and only to the extent
         that the Court of Chancery of Delaware or the court in which such
         action or suit was brought shall determine upon application that,
         despite the adjudication of liability but in view of all the
         circumstances of the case, such person is fairly and reasonably
         entitled to indemnity for such expenses which such Court of Chancery
         or such other court shall deem proper.

                 (iii)    To the extent that a Company Indemnified Person shall
         be successful on the merits or otherwise (including dismissal of an
         action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 11.4(a), or in
         defense of any claim, issue or matter therein, he shall be
         indemnified, to the fullest extent permitted by law, against expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.

                 (iv)     Any indemnification under paragraphs (i) and (ii) of
         this Section 11.4(a) (unless ordered by a court) shall be made by the
         Sponsor only as authorized in the specific case upon a determination
         that indemnification of the Company Indemnified Person is proper in
         the circumstances because he has met the applicable standard of
         conduct set forth in paragraphs (i) and (ii).  Such determination
         shall be made (1) by the Regular Trustees by a majority vote of a
         quorum consisting of such Regular Trustees who were not parties to
         such action, suit or proceeding, (2) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion, or (3) by the Holder of the Trust Common Securities.

                 (v)      Expenses (including attorneys' fees) incurred by a
         Company Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in paragraphs (i) and (ii) of this Section 11.4(a) shall be paid by
         the Sponsor in advance of the final disposition of such action, suit
         or proceeding upon receipt of an undertaking by or on behalf of such
         Company Indemnified Person to repay such amount if it shall ultimately
         be determined that he is not entitled to be indemnified by the Sponsor
         as authorized in this Section 11.4(a).  Notwithstanding the foregoing,
         no advance shall be made by the Sponsor if a determination is
         reasonably and promptly made (i) by the Regular Trustees by a majority
         vote of a quorum of disinterested Regular Trustees, (ii) if such a
         quorum is not obtainable, or, even if obtainable, if a quorum of
         disinterested Regular Trustees so directs, by independent legal
         counsel in a written opinion or (iii) the Holder of the Trust Common
         Securities, that, based upon the facts known to the Regular Trustees,
         counsel or the Holder of the Trust Common Securities at the time such
         determination is made, such Company Indemnified Person acted in bad
         faith or in a manner that such person did not believe to be in or not
         opposed to the best interests of the Trust, or, with respect to any
         criminal proceeding, that such Company Indemnified Person believed or
         had reasonable cause to believe his conduct was unlawful.  In no event
         shall any advance be made in instances where the Regular Trustees,
         independent legal counsel or Holder of the Trust Common Securities
         reasonably determine that such person deliberately breached his duty
         to the Trust or Holders of Trust Common Securities.

                 (vi)     The indemnification and advancement of expenses
         provided by, or granted pursuant to, the other paragraphs of this
         Section 11.4(a) shall not be deemed exclusive of any other rights to
         which those seeking indemnification and advancement of expenses may be
         entitled under any agreement, vote of shareholders or disinterested
         directors of the Sponsor or Holders of the Trust Preferred Securities
         or otherwise, both as to action in his official capacity and as to
         action in another capacity while holding such office.  All rights to
         indemnification under this Section 11.4(a) shall be deemed to be
         provided by a contract between the Sponsor and each Company
         Indemnified Person who serves in such capacity at any time while this
         Section 11.4(a) is in effect.  Any repeal or modification of this
         Section 11.4(a) shall not affect any rights or obligations then
         existing.





                                       39
<PAGE>   45
                 (vii)    The Sponsor or the Trust may purchase and maintain
         insurance on behalf of any person who is or was a Company Indemnified
         Person against any liability asserted against him and incurred by him
         in any such capacity, or arising out of his status as such, whether or
         not the Sponsor would have the power to indemnify him against such
         liability under the provisions of this Section 11.4(a).

                 (viii)   For purposes of this Section 11.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 11.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                 (ix)     The indemnification and advancement of expenses
         provided by, or granted pursuant to, this Section 11.4(a) shall,
         unless otherwise provided when authorized or ratified, continue as to
         a person who has ceased to be a Company Indemnified Person and shall
         inure to the benefit of the heirs, executors and administrators of
         such a person.

         (b)     The Sponsor agrees to indemnify the (i) Property Trustee, (ii)
the Delaware Trustee, (iii) any Affiliate of the Property Trustee and the
Delaware Trustee, and (iv) any officers, directors, shareholders, members,
partners, employees, representatives, custodians, nominees or agents of the
Property Trustee and the Delaware Trustee (each of the Persons in (i) through
(iv) being referred to as a "Fiduciary Indemnified Person") for, and to hold
each Fiduciary Indemnified Person harmless against, any loss, damage, claim,
liability or expense including taxes (other than taxes based on the income of
the Trustee) incurred without negligence or bad faith on the part of the
Fiduciary Indemnified Person arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder, including the
costs and expenses (including reasonable legal fees and expenses) of defending
itself against or investigating any claim or liability in connection with the
exercise or performance of any of its powers or duties hereunder.  The
obligation to indemnify as set forth in this Section 11.4(b) shall survive the
satisfaction and discharge of this Declaration.

SECTION 11.5     Outside Businesses.

         Any Covered Person, the Sponsor, the Delaware Trustee and the Property
Trustee may engage in or possess an interest in other business ventures of any
nature or description, independently or with others, similar or dissimilar to
the business of the Trust, and the Trust and the Holders of Trust 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, nor 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.

                                   ACCOUNTING

SECTION 12.1     Fiscal Year.

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

SECTION 12.2     Certain Accounting Matters.

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

         (b)     Within 60 days after May 15 of each year, the Property Trustee
shall provide to the Holders of the Trust Securities such reports as are
required by Section 313 of the Trust Indenture Act, if any, in the form and in
the manner provided by Section 313 of the Trust Indenture Act.  The Property
Trustee shall also comply with the requirements of Section 313(d) of the Trust
Indenture Act.

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

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

SECTION 12.3     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 Partnership Preferred Securities held by the Property Trustee
shall be made directly to the Property Account and no other funds of the Trust
shall be deposited in the Property 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 Account.

SECTION 12.4     Withholding.

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





                                       41
<PAGE>   47
claimed overwithholding, Holders shall be limited to an action against the
applicable jurisdiction.  If the amount required to be withheld was not
withheld from actual Distributions made, the Trust may reduce subsequent
Distributions by the amount of such withholding.  Notwithstanding anything
herein to the contrary, the Regular Trustees shall cause the Trust, absent
receipt of an opinion of nationally recognized tax counsel to the contrary, to
withhold thirty percent (30%) (or such other rate as may be imposed as a result
of an amendment to the Code or such lower rate as may be imposed under an
applicable income tax treaty) on the gross amount of any Distributions on Trust
Preferred Securities held by a Holder that is not a "United States person"
within the meaning of Section 7701(a)(30) of the Code.

there are more than two Regular Trustees a majority of the Regular Trustees) ,
the Property Trustee and the Delaware Trustee;

         (b)     No amendment shall be made, and any such purported amendment
shall be void and ineffective:

                 (i)      unless, in the case of any proposed amendment, the
         Property Trustee and the Delaware Trustee shall have first received an
         Officers' Certificate from each of the Trust and the Sponsor that such
         amendment is permitted by, and conforms to, the terms of this
         Declaration (including the terms of the Trust Securities);

                 (ii)     unless, in the case of any proposed amendment which
         affects the rights, powers, duties, obligations or immunities of the
         Property Trustee or the Delaware Trustee, the Property Trustee or the
         Delaware Trustee, as the case may be, shall have first received an
         opinion of counsel (who may be counsel to the Sponsor or the Trust)
         that such amendment is permitted by, and conforms to, the terms of
         this Declaration (including the terms of the Trust Securities); and

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

                          (A)       cause the Trust to be classified for
                 purposes of United States federal income taxation as an
                 association or a publicly traded partnership taxable as a
                 corporation;

                 Indenture Act; or

                          (D)       cause the Trust to be deemed to be an
                 Investment Company required to be registered under the 1940
                 Act.

         (c)     In the event the consent of the Property Trustee, as the
Holder of the Partnership Preferred Securities is required under the Limited
Partnership Agreement with respect to any amendment, modification or
termination of the Limited Partnership Agreement or the Partnership Preferred
Securities the Property Trustee shall request the direction of the Holders of
the Trust 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 Trust
Securities voting together as a single class; provided, however, that where a





                                       42
<PAGE>   48
consent under the Limited Partnership Agreement would require the consent of a
Super Majority of the Holders of Partnership Preferred Securities the Property
Trustee may only give such consent at the direction of the Holders of at least
the proportion in liquidation amount of the Trust Securities which the relevant
Super Majority represents of the aggregate liquidation amount of the
Partnership Preferred Securities outstanding; provided, further, that the
Property Trustee shall not be obligated to take any action in accordance with
the directions of the Holders of the Trust Securities under this Section
13.1(c) unless the Property Trustee has obtained an opinion of independent tax
counsel to the effect that as a result of such action, the Trust will not be
classified as an association or a publicly traded partnership taxable as a
corporation for United States federal income tax purposes

         (d)     At such time after the Trust has issued any Trust Securities
that remain outstanding, any amendment that would (i) adversely affect the
powers, preferences or special rights of the Trust Securities or (ii) provide
for the dissolution, winding-up or termination of the Trust other than pursuant
to the terms of this Declaration, may be effected only with the approval of the
Holders of at least a Majority in liquidation amount of the Trust Securities
affected thereby; provided, that if any amendment or proposal referred to in
clause (i) hereof would adversely affect only the Trust Preferred Securities or
the Trust 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 Trust Securities;

         (e)     Section 11.1(c) and this Section 13.1 shall not be amended
without the consent of all of the Holders of the Trust Securities;

         (f)     Article V shall not be amended without the consent of the
Holders of a Majority in liquidation amount of the Trust Common Securities;

         (g)     The rights of the Holders of the Trust Common Securities under
Article VI to increase or decrease the number of, and appoint and remove
Trustees shall not be amended without the consent of the Holders of a Majority
in liquidation amount of the Trust Common Securities; and

         (h)     Notwithstanding Section 13.1(c), this Declaration may be
amended without the consent of the Holders of the Trust Securities:

                 (i)      to cure any ambiguity;

                 (ii)     to correct or supplement any provision in this
         Declaration that may be defective or inconsistent with any other
         provision of this Declaration;

                 (iii)    to add to the covenants, restrictions or obligations
         of the Sponsor;

                 (iv)     to conform to any change in the 1940 Act or written
         change in interpretation or application of the rules and regulations

SECTION 13.2     Meetings of the Holders of Trust Securities; Action by Written
                 Consent.

         (a)     Meetings of the Holders of any class of Trust Securities may
be called at any time by the Regular Trustees (or as provided in the terms of
the Trust Securities) to consider and act on any matter on which Holders of
such class of Trust Securities are entitled to act under the terms of this
Declaration, the terms of the Trust Securities, the Limited Partnership
Agreement, the rules of any stock exchange on which the Trust Preferred
Securities are listed or admitted for trading, the Business Trust Act or other
applicable law.  The Regular Trustees shall call a meeting of the Holders of
such class if directed to do so by the Holders of at least 10% in liquidation
amount of such class of Trust Securities.  Such direction shall be given by
delivering to the Regular Trustees one or more calls in a writing stating that
the signing Holders of Trust Securities wish to call a meeting and indicating
the general or specific purpose for which the meeting is to be called.  Any
Holders of Trust Securities calling a meeting shall specify in writing the
Certificates held by the Holders of Trust Securities exercising the right to
call a meeting and only those Trust 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
Trust Securities, the following provisions shall apply to meetings of Holders
of Trust Securities:

                 (i)      notice of any such meeting shall be given to all the
         Holders of Trust Securities having a right to vote thereat at least 7
         days and not more than 60 days before the date of such meeting.  Any
         action that may be taken at a meeting of the Holders of Trust
         Securities may be taken without a meeting if a consent in writing
         setting forth the action so taken is signed by the Holders of Trust
         Securities owning not less than the minimum amount of Trust Securities
         in liquidation amount that would be necessary to authorize or take
         such action at a meeting at which all Holders of Trust 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 Trust Securities entitled to vote who have not consented in
         writing.  The Regular Trustees may specify that any written ballot
         submitted to the Holder for the purpose of taking any action without a
         meeting shall be returned to the Trust within the time specified by
         the Regular Trustees;

                 (ii)     each Holder of a Trust Security may authorize any
         Person to act for it by proxy on all matters in which a Holder of
         Trust 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 Trust 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 Trust Securities were shareholders
         of a Delaware corporation;

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

                 (iv)     unless the Business Trust Act, this Declaration, the
         terms of the Trust Securities, the Trust Indenture Act or the listing
         rules of any stock exchange on which the Trust Preferred Securities
         are then listed for trading, otherwise provide, the Regular Trustees,
         in their sole discretion, shall establish all other provisions
         relating to meetings of Holders of Trust 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 Trust 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.

                             [REVERSE OF SECURITY]

      Holders of Trust Preferred Securities shall be entitled to receive
cumulative cash distributions at a rate per annum of 8.30% of the stated
liquidation amount of $25 per Trust Preferred Security.  Distributions on the
Trust Preferred Securities shall, from the date of original issue, accrue and
be cumulative and shall be payable quarterly only to the extent that the Trust
has funds available for the payment of such distributions in the Property
Account.  Distributions not paid on the scheduled payment date will accumulate
and compound quarterly (to the extent permitted by applicable law) at the rate
of  8.30% per annum.  The term "Distributions" as used herein shall mean
ordinary cumulative distributions in respect of each Fiscal Period together
with any such Compounded Distributions.  Amounts available to the Trust for
distribution to the holders of the Trust Preferred Securities will be limited
to payments received by the Trust from the Partnership on the Partnership
Preferred Securities or from the Company on the Partnership Guarantee.
Distributions on the Partnership Preferred Securities will be paid only if, as
and when declared in the sole discretion of the Company, as the General Partner
of the Partnership.  If and to the extent that the Partnership makes a
distribution on the Partnership Preferred Securities held by the Property
Trustee or the Company makes a payment under the Partnership Guarantee (the
amount of any such partnership distribution, including any compounded
partnership distributions or guarantee payment being a "Payment Amount"), the
Trust shall and the Property Trustee is directed, to the extent funds are
available for that purpose, to make a Pro Rata Distribution of the Payment
Amount to Holders.

      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 on the basis of the actual number of days elapsed in a 90-day quarter.

      Except as otherwise described herein, distributions on the Trust
Preferred Securities will be cumulative, will accrue from the date of initial
issuance and will be payable quarterly in arrears, on March 31, June 30,
September 30 and December 31 of each year, commencing on December 31, 1996 if,
as and when available for payment by the Property Trustee.  If the Trust
Preferred Securities (or, if the Trust is liquidated, the Partnership Preferred
Securities) are in book-entry-only form, Distributions will be payable to the
Holders of record of Trust Preferred Securities as they appear on the books and
records of the Trust on the relevant record dates, which will be one Business
Day prior to the relevant payment dates.  If the Trust Preferred Securities
(or, if the Trust is liquidated, the Partnership Preferred Securities) do not
remain in book-entry-only form, the relevant record dates shall be the 15th day
of the month of the relevant payment dates.  In the event that any date on
which distributions are payable is not a Business Day, payment of such
Distribution shall be made on the next succeeding day which is a Business Day
(without any interest or other payment in respect of any such delay) except
that, if such Business Day falls in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day (without any
reduction of interest or other payments in respect of such early payment).
Payments of accrued Distributions will be payable to Holders of record of Trust
Preferred Securities as they appear on the books and records of the Trust on
the record date with respect to the payment date for the Trust Preferred
Securities which corresponds to the payment date fixed by the Partnership with
respect to the payment of cumulative distributions on the Partnership Preferred
Securities.

      The Trust Preferred Securities shall be redeemable as provided in the
Declaration.

                                   ARTICLE IV

                                  ALLOCATIONS

         Section 4.1      PROFITS AND LOSSES.  After giving effect to the
special allocation provisions set forth in Section 4.2, which special
allocations shall take precedence over any allocations made pursuant to this
Section 4.1,

         (a)     the Partnership's Net Income for each Fiscal Period of the
Partnership shall be allocated as follows:

                 (i)      First, to each Holder of a Partnership Preferred
         Security in an amount equal to the excess, if any, of (x) the amount
         of Net Losses, if any, allocated to each such Holder from the date of
         issuance of the Partnership Preferred Security through and including
         the close of such Fiscal Period pursuant to Section 4.1(b)(ii) below
         over (y) the amount of Net Income, if any, allocated to each such
         Holder pursuant to this Section 4.1(a)(i) in all prior Fiscal Periods.

                 (ii)     Second, to the Holders of the Partnership Preferred
         Securities, an amount of Net Income equal to the excess of (x) the
         Distributions accrued on the Partnership Preferred Securities from the
         date of their issuance through and including the last day of such
         Fiscal Period, including any Compounded Distributions payable with
         respect thereto, over (y) the amount of Net Income allocated to the
         Holders of the Partnership Preferred Securities pursuant to this
         Section 4.1(a)(ii) in all prior Fiscal Periods.  Amounts allocated to
         all Partnership Preferred Security Holders shall be allocated among
         such Holders in proportion to the number of Partnership Preferred
         Securities held by such Holders.

                 (iii)    Any remaining Net Income shall be allocated to the 
         General Partner.

         (b)     The Partnership's Net Loss for any Fiscal Period shall be
allocated as follows:

                 (i)      First, to the General Partner until the balance of
         the General Partner's Capital Account is reduced to zero, provided,
         however, that the aggregate amount of Net Losses allocated to the
         General Partner pursuant to this Section 4.1(b)(i) shall not exceed
         the sum of 14% of the total capital contributions of all Partners plus
         the aggregate Net Income allocated to the General Partner pursuant to
         this Section 4.1.

                 (ii)     Second, among the Holders in proportion to their
         respective aggregate Capital Account balances, until the Capital
         Account balances of such Holders are reduced to zero.

                 (iii)    Any remaining Net Loss shall be allocated to the 
         General Partner.

         (c)     Daily Determination.  For purposes of determining the profits,
losses or any other items allocable to any period, profits, losses and any such
other items shall be determined on a daily basis, unless the General





                                       9
<PAGE>   15
Partner determines that another method is permissible under Section 704 of the
Code and the Treasury Regulations promulgated thereunder.  Unless otherwise
specified, such profits, losses or other items shall be determined for each
Fiscal Period.

         Section 4.2      SPECIAL ALLOCATION.

         (a)     All expenditures that are (i) incurred by, or on behalf of,
the Partnership and (ii) paid, or otherwise reimbursed, by the General Partner
out of its own funds shall be allocated entirely to the General Partner.

         (b)     In the event any Partner unexpectedly receives any
adjustments, allocations or distributions described in Treasury Regulation
Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of the Partnership's Net
Income shall be specially allocated to such Partner in a manner sufficient to
eliminate the deficit, if any, in the balance of the Capital Account of such
Partner as quickly as possible.  The foregoing is intended to be a "qualified
income offset" provision as described in Treasury Regulation Section
1.704-1(b)(2)(ii)(d) and shall be interpreted and applied in all respects in
accordance with such Treasury Regulation.

         (c)     Section 704 Compliance.  While this Agreement does not
specifically provide for certain provisions required by Treasury Regulation
Sections 1.704-1(b) and 1.704-2 because those provisions apply to transactions
that are not expected to occur as regards the Partnership, the Partners intend
that the allocations under Section 4.1 conform to Treasury Regulations Sections
1.704-1(b) and 1.704-2 (including, without limitation, the minimum gain
chargeback, chargeback of partner nonrecourse debt minimum gain and partner
nonrecourse debt provisions of such Treasury Regulations), and, to the extent
necessary due to the occurrence of unexpected events, the General Partner shall
make such changes in the allocations under Section 4.1 as it believes are
reasonably necessary to meet the requirements of such Treasury Regulations.

         (d)     Adjustment of Allocations.  If the allocations set forth in
this Article IV are adjusted by the Internal Revenue Service and the Tax
Matters Partner agrees to such adjustments, such allocations shall be amended
to the minimum extent necessary to conform with such adjustments.

         (e)     Additional Allocations.  Notwithstanding the foregoing, if,
upon the final dissolution and termination of the Partnership and after taking
into account all allocations of Net Income and Net Losses (and other tax items)
under this Article IV, the distributions to be made in accordance with the
positive Capital Account balances would result in a distribution that would be
different from a distribution under Article XIII, then gross items of income
and gain (and other tax items) for the taxable year of the final dissolution
and termination (and, to the extent permitted under section 761(c) of the Code,
gross items of income and gain, and other tax items, for the immediately
preceding taxable year) shall be allocated to the Partners to increase or
decrease their respective Capital Account balances so that the final
distribution will occur in the same manner as a distribution under Section
13.4.

         (f)     General Partner Allocations.  Notwithstanding any provision of
this Agreement to the contrary, the interest of the General Partner in each
item of Partnership income, gain, loss, deduction, or credit shall, at all
times during the existence of the Partnership, be equal to at least (A) at any
time that the aggregate capital contributions to the Partnership are equal to
or less than $50,000,000, one percent (1%) of each such item and (B) at any
time that the aggregate capital contributions to the Partnership are greater
than $50,000,000, at least a percentage equal to the product of (i) one percent
(1%) and (ii) a fraction (not exceeding 1 and not less than 0.2), the numerator
of which is $50,000,000 and the denominator of which is the lesser of (x) the
aggregate Capital Account balances of the Capital Accounts of all Partners at
such time and (y) the aggregate capital contributions to the Partnership of all
Partners at such time.

         Section 4.3      WITHHOLDING.  The Partnership shall comply with
withholding requirements under federal, state and local law and shall remit
amounts withheld to and file required forms with applicable jurisdictions.  To
the extent that the Partnership is required to withhold and pay over any
amounts to any authority with respect to distributions or allocations to any
Partner, the amount withheld shall be deemed to be a distribution





                                       10
<PAGE>   16
in the amount of the withholding to the Partner.  In the event of any claimed
over-withholding, Partners shall be limited to an action against the applicable
jurisdiction.  If the amount withheld was not withheld from actual
distributions, the Partnership may reduce subsequent distributions by the
amount of such withholding.  Each Partner agrees to furnish the Partnership
with any representations and forms as shall reasonably be requested by the
Partnership to assist it in determining the extent of, and in fulfilling, its
withholding obligations.


                                   ARTICLE V

                                 DISTRIBUTIONS

         Section 5.1      DISTRIBUTIONS.  Limited Partners shall receive
periodic Distributions and Compounded Distributions, if any, redemption
payments and liquidation distributions in accordance with the terms of the
Partnership Preferred Securities set forth in Article VI.  The General Partner
shall in its sole discretion determine whether and when Distributions shall be
payable; provided, however, that if the General Partner shall determine a
Distribution will not be paid on a scheduled Distribution Payment Date, the
General Partner shall give notice of its determination not to pay such
Distribution to Limited Partners of record as of the Record Date for the
payment of such Distribution; provided, further, however, that the General
Partner shall not declare distributions, and no distributions shall be payable
by the Partnership to the General Partner in respect of its General Partner
Interest unless all accumulated and unpaid Distributions, including any
Compounded Distributions, have been paid in full for all prior Fiscal Periods.
Subject to the immediately preceding sentence, to the extent that the aggregate
payments of interest (or dividends) received by the Partnership in respect of
Affiliate Investment Instruments and Eligible Debt Securities for each Fiscal
Period exceed the amount of Distributions, including any Compounded
Distributions, paid on the Partnership Preferred Securities for such Fiscal
Period, the General Partner, in its sole discretion may declare and distribute
such excess funds to the General Partner in respect of its General Partner
Interest.

         Section 5.2      LIMITATIONS ON DISTRIBUTIONS.  The Partnership shall
not make a Distribution to any Partner on account of such Partner's Interest if
such Distribution would violate Section 17-607 of the Act or other applicable
law.


                                   ARTICLE VI

                  ISSUANCE OF PARTNERSHIP PREFERRED SECURITIES

         (b)     The payment of Distributions (including payments of

to and to the extent set forth in the Partnership Guarantee.  The Partnership
Preferred Security Holders hereby authorize the General Partner to hold the
Guarantee on behalf of the Partnership Preferred Security Holders.  In the
event of an appointment of a Special Representative pursuant to Section 6.2(i),
among other things, to enforce the Partnership Guarantee, the Special

Partnership Guarantee, the General Partner has the right to enforce the
Partnership Guarantee on behalf of the Partnership Preferred Security Holders.

Preferred Securities, acknowledge and agree to the subordination provisions in,

<PAGE>   17
         (c)     The Partnership may not issue any interests in the Partnership

Partner Interest.  All Partnership Preferred Securities shall rank senior to
all other Interests in the Partnership in respect of the right to receive
Distributions.  All Partnership Preferred Securities redeemed, purchased or
otherwise acquired by the Partnership shall be canceled.  The Partnership
Preferred Securities will be issued in registered form only.

new or additional limited partnership interests, or of securities convertible
into any Partnership Preferred Securities or other limited partnership
interests, whether now or hereafter authorized and whether issued for cash or
other consideration or by way of a distribution.

         (e)     Any of the Partnership Preferred Securities that are owned by
the Company or by any entity more than 50% of which is owned by the Company,
either directly or indirectly, shall not be entitled to vote or consent with
respect to any Partnership Preferred Security owned by it, and shall, for
purposes of such vote or consent, be treated as if they were not outstanding;
provided, however, that persons otherwise eligible to vote to whom the Company
or any of its subsidiaries have pledged Partnership Preferred Securities may
vote or consent with respect to such pledged Partnership Preferred Securities
under any of the circumstances described in Section 6.2.

         Section 6.2      PARTNERSHIP PREFERRED SECURITIES.

         (a)     Designation.  A total of 8,247,440 Partnership Preferred
Securities, liquidation preference $25 per Partnership Preferred Security, are
hereby designated as "8.30% Partnership Preferred Securities".

         (b)     Distributions.

                 (i)      Partnership Preferred Security Holders shall be
         entitled to receive cumulative Distributions and Compounded
         Distributions (as defined below) (if any), if, as and when declared by
         the General Partner, in its sole discretion, out of the assets of the
         Partnership legally available therefor, at a rate per annum of 8.30%
         of the stated liquidation preference of $25 per Partnership Preferred
         Security, calculated on the basis of a 360-day year consisting of
         twelve 30-day months.  For any period shorter than a full 90-day
         quarter, Distributions will be computed on the basis of the actual
         number of days elapsed in such 90-day quarter.  Such Distributions
         shall, from the date of original issue, accrue and be cumulative and
         shall be payable quarterly, when, if, and as declared by the General
         Partner on the dates specified in Section 6.2(b)(ii) below.
         Distributions and Compounded Distributions (as defined below) (if any)
         on the Partnership Preferred Securities shall be cumulative from the
         Closing Date.  Distributions not paid on the scheduled Distribution
         Payment Date will accumulate and compound quarterly at the rate of
         8.30% per annum ("Compounded Distributions").  In the event that any
         date on which Distributions are payable on the Partnership Preferred
         Securities is not a Business Day, then payment of the Distribution
         payable on such date will be made on the next succeeding day which is
         a Business Day (and without any interest or other payment in respect
         of any such delay) except that, if such Business Day is in the next
         succeeding calendar year, such payment shall be made on the
         immediately preceding Business Day (without any reduction in interest
         or other amounts in respect of such early payment).

                 (ii)     Distributions on the Partnership Preferred Securities
         will be payable quarterly in arrears if, as and when, declared by the
         General Partner on March 31, June 30, September 30 and December 31 of
         each year, commencing on December 31, 1996 (each a "Distribution
         Payment Date").

                 Distributions will be payable to the Holders as they appear on
         the books and records of the Partnership on the relevant Record Date.
         If the Trust or the Property Trustee is the Holder of the Partnership
         Preferred Securities, all distributions of cash shall be made by wire
         transfer of same day funds to such Holder by 10:00 a.m., New York City
         time, on the applicable Distribution Payment Date.  Distributions
         payable on any Partnership Preferred Securities that are not
         punctually paid on any Distribution





                                       12
<PAGE>   18
         Payment Date will cease to be payable to the Person in whose name such
         Partnership Preferred Securities are registered on the relevant record
         date, and such Distribution will instead be payable to the Person in
         whose name such Partnership Preferred Securities are registered on the
         record date for payment of such defaulted or accrued Distribution.

         (c)     Optional Redemption.  Partnership Preferred Securities shall
be redeemable at the option of the General Partner, in whole or in part, from
time to time, on or after December 31, 2001, upon not less than 30 nor more
than 60 days' notice, at an amount per Partnership Preferred Securities equal
to $25 plus accrued and unpaid Distributions thereon, including any Compounded
Distributions (the "Redemption Price").  The Partnership may not redeem the
Partnership Preferred Securities in part unless all accumulated and unpaid
Distributions, including any Compounded Distributions, have been paid in full
on all Partnership Preferred Securities for all Fiscal Periods terminating on
or prior to the date of redemption.  If a partial redemption of the Partnership
Preferred Securities would result in the delisting of the Trust Preferred
Securities (or, if the Trust is liquidated in connection with a Trust Special
Event, the delisting of the Partnership Preferred Securities), the Partnership
may only redeem the Partnership Preferred Securities in whole but not in part.

         (d)     Special Event Redemptions.  (i)  If, at any time, a
Partnership Special Event shall occur and be continuing, the General Partner
shall, within 90 days following the occurrence of such Partnership Special
Event, elect to either (i) redeem the Partnership Preferred Securities in whole
(but not in part), upon not less than 30 or more than 60 days' notice at the
Redemption Price, provided that if at the time there is available to the
Partnership the opportunity to eliminate, within such 90-day period, the
Partnership Special Event by taking some ministerial action, such as filing a
form or making an election, or pursuing some other similar reasonable measure
that in the sole judgment of the General Partner has or will cause no adverse
effect on the Partnership, the Trust, or the Company, the General Partner will
pursue such measure in lieu of redemption; or (ii) cause the Partnership
Preferred Securities to remain outstanding, provided that in the case of this
clause (ii), the General Partner shall pay any and all costs and expenses
incurred by or payable by the Partnership which are attributable to the
Partnership Special Event.

         (e)     Redemption Procedures.

                 (i)      Notice of any redemption of Partnership Preferred
         Securities (a "Redemption Notice") will be given by the General
         Partner on behalf of the Partnership by mail to each Holder of
         Partnership Preferred Securities to be redeemed not fewer than 30 nor
         more than 60 days before the date fixed for redemption.  For purposes
         of the calculation of the date of redemption and the dates on which
         notices are given pursuant to this Section 6.2(e)(i), a Redemption
         Notice shall be deemed to be given on the day such notice is first
         mailed, by first-class mail, postage prepaid, to Holders of
         Partnership Preferred Securities.  Each Redemption Notice shall be
         addressed to the Holders of Partnership Preferred Securities at the
         address of each such Holder appearing in the books and records of the
         Partnership.  No defect in the Redemption Notice or in the mailing
         thereof with respect to any Holder shall affect the validity of the
         redemption proceedings with respect to any other Holder.

                 (ii)     In the event that fewer than all the outstanding
         Partnership Preferred Securities are to be redeemed, the Partnership
         Preferred Securities to be redeemed shall be redeemed pro rata
         provided, that, in the event Partnership Preferred Securities are held
         in book-entry only form by DTC or its nominee (or any successor
         Clearing Agency or its nominee), DTC will reduce, in accordance with
         DTC's customary procedures, the amount of the interest of each
         Clearing Agency Participant in the Partnership Preferred Securities to
         be redeemed.

                 (iii)    If the Partnership gives a Redemption Notice (which
         notice will be irrevocable), then by 12:00 noon, New York City time,
         on the redemption date, the General Partner on behalf of the
         Partnership (A) if the Partnership Preferred Securities are in
         book-entry only form with DTC, will deposit irrevocably with DTC funds
         sufficient to pay the applicable Redemption Price and will give DTC
         irrevocable instructions and authority to pay the Redemption Price in
         respect of the Partnership Preferred Securities held





                                       13
<PAGE>   19
         through DTC in global form or (B) if the Partnership Preferred
         Securities are held in certificated form, will deposit with the Paying
         Agent, funds sufficient to pay the applicable Redemption Price of the
         amount of any such Partnership Preferred Securities and will give to
         the Paying Agent irrevocable instructions and authority to pay such
         amounts to the Holders of Partnership Preferred Securities, upon
         surrender of their certificates, by check, mailed to the address of
         the relevant Holder appearing on the books and records of the
         Partnership on the redemption date; provided, however, that for so
         long as the Trust or the Property Trustee of the Trust shall hold the
         Partnership Preferred Securities, payment of cash shall be made by
         wire in same day funds to the Holder by 12:00 Noon, New York City
         time, on the redemption date.  For these purposes, the applicable
         Redemption Price shall not include Distributions which are being paid
         to Holders who were Holders on a relevant record date.  Upon
         satisfaction of the foregoing conditions, then immediately prior to
         the close of business on the date of such deposit or payment, all
         rights of Holders of such Partnership Preferred Securities so called
         for redemption will cease, except the right of the Holders to receive
         the Redemption Price, but without interest on such Redemption Price,
         and from and after the date fixed for redemption, such Partnership
         Preferred Securities will not accrue distributions or bear interest.

                 In the event that any date fixed for redemption of Partnership
         Preferred Securities is not a Business Day, then payment of the
         Redemption Price payable on such date will be made on the next
         succeeding Business Day (and without any interest 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 (without any reduction in interest on other amounts in
         respect of any such early payment).  In the event that payment of the
         Redemption Price is improperly withheld or refused and not paid by
         either the Partnership or the Company pursuant to the Partnership
         Guarantee, Distributions on the Partnership Preferred Securities
         called for Redemption will continue to accrue, to the extent that
         payment of such interest is legally available, from the original
         redemption date until the Redemption Price is actually paid.

                 The Partnership shall not be required to register or cause to
         be registered the transfer of any Partnership Preferred Securities
         which have been called for redemption.

         (f)     Company Purchases.  Subject to the provisions of this Section
6.2 and applicable law (including, without limitation, Federal securities
laws), if Partnership Preferred Securities have been distributed to the Holders
(as defined in the Declaration) of Trust Preferred Securities, the Company or
any of its subsidiaries may at any time and from time to time purchase
outstanding Partnership Preferred Securities by tender, in the open market, or
by private agreement.

         (g)     Liquidation Distribution Upon Dissolution.  In the event of
any voluntary or involuntary liquidation, dissolution, winding-up or
termination of the Partnership, the Holders of Partnership Preferred Securities
at the time outstanding will be entitled to receive out of the assets of the
Partnership such amount as is determined in accordance with Section 13.4 (the
"Partnership Liquidation Distribution") payable in cash.

         (h)      Voting Rights.

         (i)      Special Representative.

                 (1)      If one or more of the following events shall occur
         and be continuing (each a "Partnership Enforcement Event"):  (i)
         arrearages on distributions on the Partnership Preferred Securities
         shall exist for six consecutive quarterly distribution periods, (ii)
         the Company is in default on any of its obligations under the
         Partnership Guarantee or (iii) an Investment Event of Default on any
         Affiliate Investment Instrument or a default under any Investment
         Guarantee, as the case may be, the Holders of the Partnership
         Preferred Securities, upon the affirmative vote of at least a Majority
         in Liquidation Preference of the Partnership Preferred Securities,
         shall have the right, to the exclusion of the General Partner,  (a) to
         appoint and authorize a special representative of the Partnership and
         the Limited Partners (a "Special Representative") to enforce (1) to
         the maximum extent permitted by applicable law, the Partnership's
         creditors' rights and other rights with respect to the Affiliate
         Investment Instruments and the Investment





                                       14
<PAGE>   20
         Guarantees, (2) the rights of the Holders of the Partnership Preferred
         Securities under the Partnership Guarantee, and (3) the rights of the
         Holders of the Partnership Preferred Securities to receive
         Distributions (only if, and to the extent, declared by the General
         Partner, in its sole discretion, out of funds legally available
         therefor) on the Partnership Preferred Securities, and (b) under the
         Partnership Guarantee to enforce the terms of the Partnership
         Guarantee, including the right to enforce the covenant restricting
         certain payments.  Under no circumstances, however, shall the Special
         Representative have authority to cause the General Partner to declare
         Distributions on the Partnership Preferred Securities or have any
         authority concerning the selection of Partnership Investments.  When
         the Special Representative acts to enforce the Partnership's
         creditors' rights and other rights with respect to the Affiliate
         Investment Instruments and the Investment Guarantees, the Special
         Representative acts as an agent of the Partnership.  When the Special
         Representative acts to enforce the rights of the Holders of the
         Partnership Preferred Securities under the Partnership Guarantee or
         their rights to receive Distributions on the Partnership Preferred
         Securities, the Special Representative acts as an agent of the Holders
         of the Partnership Preferred Securities.  In addition, the Special
         Representative shall not, by virtue of acting in such capacity, be
         admitted as a general or limited partner in the Partnership or
         otherwise be deemed to be a general or limited partner in the
         Partnership and shall have no liability for the debts, obligations, or
         liabilities of the Partnership.

                 (2)      In furtherance of the foregoing, and without limiting
         the powers of any Special Representative so appointed and to avoid any
         doubt concerning the powers of the Special Representative, any Special
         Representative, in its own name, in the name of the Partnership,  in
         the name of the Limited Partners, or otherwise, may institute, or
         cause to be instituted, a proceeding, including, without limitation,
         any suit in equity, an action at law or other judicial or
         administrative proceeding, to enforce on behalf of the Partnership the
         Partnership's rights directly against the Company or any other obligor
         in connection with its obligations to the Partnership, and may
         prosecute such proceeding to judgment or final decree, and enforce the
         same against the Company or any other obligor in connection with such
         obligations and collect, out of the property, wherever situated, of
         the Company or any such other obligor upon such obligations, the
         monies adjudged or decreed to be payable in the manner provided by
         law.  The General Partner agrees to execute and deliver such documents
         as may be necessary, appropriate or convenient for the Special
         Representative to enforce the foregoing rights and obligations on
         behalf and in the name of the Partnership.

                 (3)      If the Special Representative fails to enforce its
         rights under any Affiliate Investment Instrument after a holder of
         Partnership Preferred Securities has made a written request, such
         holder of record of Partnership Preferred Securities may to the
         fullest extent permitted by law directly institute a legal proceeding
         against the applicable Investment Affiliate to enforce the rights of
         the Special Representative and the Partnership under the Affiliate
         Investment Instrument without first instituting any legal proceeding
         against the Special Representative, the Partnership or any other
         person or entity.  In any event, if a Partnership Enforcement Event
         has occurred and is continuing and such event is attributable to the
         failure of an Investment Affiliate to make any required payment when
         due on any Affiliate Investment Instrument, then a holder of
         Partnership Preferred Securities may to the fullest extent permitted
         by law on behalf of the Partnership directly institute a proceeding
         against such Investment Affiliate with respect to such Affiliate
         Investment Instrument for enforcement of payment.  In addition, the
         Partnership acknowledges that, for so long as the Trust holds any
         Partnership Preferred Securities, if the Special Representative fails
         to enforce its rights on behalf of the Partnership under the Affiliate
         Investment Instruments after a holder of Trust Securities has made a
         written request, a holder of record of Trust Securities may to the
         fullest extent permitted by law on behalf of the Partnership directly
         institute a legal proceeding against the Investment Affiliates under
         the Affiliate Investment Instruments, without first instituting any
         legal proceeding against the Property Trustee, the Trust, the Special
         Representative or the Partnership.  In any event, for so long as the
         Trust is the holder of any Partnership Preferred Securities, if a
         Trust Enforcement Event has occurred and is continuing and such event
         is attributable to the failure of an Investment Affiliate to make any
         required payment when due on any Affiliate Investment Instrument or
         the failure of the Company to make any required payment when due on
         any Investment Guarantee, then





                                       15
<PAGE>   21
         the Partnership acknowledges that a holder of Trust Securities may to
         the fullest extent permitted by law on behalf of the Partnership
         directly institute a proceeding against such Investment Affiliate with
         respect to such Affiliate Investment Instrument or against the Company
         with respect to any such Investment Guarantee, in each case for
         enforcement of payment.  Under no circumstances shall the Special
         Representative, any holder of Partnership Preferred Securities or any
         holder of Trust Preferred Securities have authority to cause the
         General Partner to declare distributions on the Partnership Preferred
         Securities.


                 (4)      For purposes of determining whether the Partnership
         has deferred payment of Distributions for six (6) consecutive
         quarters, Distributions shall be deemed to remain in arrears,
         notwithstanding any payments in respect thereof, until full cumulative
         Distributions, including Compounded Distributions, have been or
         contemporaneously are paid with respect to all quarterly Distribution
         periods terminating on or prior to the date of payment of such full
         cumulative Distributions.  Not later than 30 days after such right to
         appoint a Special Representative arises, the General Partner will
         convene a meeting for election of a Special Representative.  If the
         General Partner fails to convene such meeting within such 30-day
         period, the Holders of not less than 10% in Liquidation Preference of
         the Outstanding Partnership Preferred Securities will be entitled to
         convene such meeting.  The provisions of Section 14.3 relating to the
         convening and conduct of meetings of the Partners will apply with
         respect to any such meeting.  In the event that, at any such meeting,
         Holders of less than a Majority in Liquidation Preference of
         Partnership Preferred Securities entitled to vote for the appointment
         of a Special Representative vote for such appointment, no Special
         Representative shall be appointed.  Any Special Representative
         appointed shall cease to be a Special Representative of the
         Partnership and/or the Limited Partners if (x) the Partnership (or the
         Company pursuant to the Partnership Guarantee) shall have paid in full
         all accrued and unpaid Distributions on the Partnership Preferred
         Securities, (y) the relevant Investment Event of Default shall have
         been cured, and (z) the Company is in compliance with all its
         obligations under the Partnership Guarantee, and the Company, in its
         capacity as the General Partner, shall continue the activities of the
         Partnership without dissolution.  Notwithstanding the appointment of
         any such Special Representative, the Company shall continue as General
         Partner and shall retain all rights under this Agreement, including
         the right to determine whether to declare, in its sole discretion, the
         payment of Distributions on the Partnership Preferred Securities.

                 (ii)     Certain Amendments; Waiver.  (1)  If any proposed
         amendment of this Agreement provides for, or the General Partner
         otherwise proposes to effect, (x) any action that would adversely
         affect the powers, preferences or special rights of the Holders of the
         Partnership Preferred Securities, whether by way of amendment of this
         Agreement or otherwise (including, without limitation, the
         authorization or issuance of any limited partnership interests in the
         Partnership ranking, as to participation in profits or distributions,
         or in the assets of the Partnership, senior to the Partnership
         Preferred Securities); or (y) the dissolution, winding-up or
         termination of the Partnership, other than (1) in connection with the
         occurrence of a Partnership Special Event or (2) as described under
         Sections 11.11 and 13.2 of this Agreement, then the Holders of
         outstanding Partnership Preferred Securities will be entitled to vote
         on such amendment or proposal of the General Partner (but not on any
         other amendment or proposal) as a class and such amendment or proposal
         shall not be effective except with the approval of Holders of a
         Majority in Liquidation Preference of such outstanding Partnership
         Preferred Securities having a right to vote on the matter; provided,
         however, that if the Property Trustee on behalf of the Trust is the
         Holder of the Partnership Preferred Securities, any such amendment or
         proposal not excepted by (1) or (2) above shall not be effective
         without the prior or concurrent approval of the Holders of a majority
         in liquidation amount of the outstanding Trust Preferred Securities
         having a right to vote on such matters; provided, further that no such
         approval shall be required if the dissolution, winding-up or
         termination of the Partnership is proposed or initiated upon the
         initiation of proceedings, or after proceedings have been initiated,
         for the dissolution, winding-up, liquidation or termination of the
         Company.

                          (2)     The Holders of a Majority in Liquidation
                 Preference of Partnership Preferred Securities may, by vote,
                 on behalf of the Holders of all of the Partnership Preferred
                 Securities,





                                       16
<PAGE>   22
                 waive any past Partnership Enforcement Event with respect to
                 the Partnership Preferred Securities and its consequences;
                 provided that, if the underlying Investment Event of Default:

                 (A)      is not waivable under the related Affiliate
                          Investment Instrument, such Partnership Enforcement
                          Event shall also not be waivable; or

                 (B)      requires the consent or vote of the Holders of
                          greater than a majority in principal amount or
                          liquidation preference of the Affiliate Investment
                          Instruments (a "Super Majority") to be waived under
                          the related Affiliate Investment Instrument, the
                          Partnership Enforcement Event may only be waived by
                          the vote of the Holders of the relevant Super
                          Majority in liquidation amount of the Partnership
                          Preferred Securities.

                 Upon such waiver, any such Partnership Enforcement Event shall
                 cease to exist, and shall be deemed to have been cured, for
                 every purpose of this Agreement, but no such waiver shall
                 extend to any subsequent or other Partnership Enforcement
                 Event or impair any right consequent thereon.

                          (3)     A waiver of an Investment Event of Default by
                 the Special Representative, acting at the direction of the
                 Holders of the Partnership Preferred Securities, constitutes a
                 waiver of the corresponding Partnership Enforcement Event.

                 (iii)    General Voting.  (1)  Neither the General Partner nor
         the Special Representative shall (i) direct the time, method and place
         of conducting any proceeding for any remedy available, (ii) waive any
         Investment Event of Default that is waivable under the Affiliate
         Investment Instruments, (iii) exercise any right to rescind or annul a
         declaration that the principal of any Affiliate Investment Instruments
         that are debt instruments shall be due and payable, (iv) waive the
         breach of the covenant by the Company in the Partnership Guarantee to
         restrict certain payments, or (v) consent to any amendment,
         modification or termination of any Affiliate Investment Instrument,
         where such consent shall be required from the holder thereof, without,
         in each case, obtaining the prior approval of the Holders of at least
         a Majority in Liquidation Preference of the Partnership Preferred
         Securities; provided, however, that if the Property Trustee on behalf
         of the Trust is the Holder of the Partnership Preferred Securities,
         such waiver, consent or amendment or other action shall not be
         effective without the prior or concurrent approval of at least a
         majority in liquidation amount of the outstanding Trust Preferred
         Securities having a right to vote on such matters.  The General
         Partner shall not revoke any action previously authorized or approved
         by a vote of the Holders of the Partnership Preferred Securities.  The
         General Partner shall notify all Holders of the Partnership Preferred
         Securities of any notice of an Investment Event of Default received
         with respect to any Affiliate Investment Instrument.

                 (2)      Any required approval of Holders of Partnership
         Preferred Securities may be given at a separate meeting of such
         Holders convened for such purpose or pursuant to written consent.  The
         General Partner will cause a notice of any meeting at which Holders of
         Partnership Preferred Securities are entitled to vote, or of any
         matter upon which the action by written consent of such Holders is to
         be taken, to be mailed to each Holder of record of Partnership
         Preferred Securities.  Each such notice will include a statement
         setting forth (x) the date of such meeting or the date by which such
         action is to be taken, (y) a description of any matter proposed for
         adoption at such meeting on which such Holders are entitled to vote or
         of such matters upon which written consent is sought and (z)
         instructions for the delivery of proxies or consents.  No vote or
         consent of the Holders of Partnership Preferred Securities will be
         required for the Partnership to redeem and cancel Partnership
         Preferred Securities in accordance with this Agreement.

                 (3)      Notwithstanding that Holders of Partnership Preferred
         Securities are entitled to vote or consent under any of the
         circumstances described above, any of the Partnership Preferred
         Securities at such time that are owned by the Company or by any entity
         more than 50% of which is owned by the

         Company, either directly or indirectly, 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; provided, however, that persons
         otherwise eligible to vote to whom the Company or any of its
         subsidiaries have pledged Partnership Preferred Securities may vote or
         consent with respect to such pledged Partnership Preferred Securities
         under any of the circumstances described herein.

                 (4)      Holders of the Partnership Preferred Securities shall
         have no rights to remove or replace the General Partner.

                 (5)      Holders of Partnership Preferred Securities shall
         have no preemptive rights.


                                  ARTICLE VII

                            PARTNERSHIP INVESTMENTS

         Section 7.1      INITIAL AFFILIATE INVESTMENT INSTRUMENTS.

         (a)     All Partnership funds will be invested in the securities of
Investment Affiliates (the "Affiliate Investment Instruments") and Eligible
Debt Securities.  No more than 99% of the Initial Partnership Proceeds will be
used by the Partnership to purchase the Initial Debentures meeting the criteria
set forth in this Section 7.1.  The remaining funds from the Initial
Partnership Proceeds will be used to purchase Eligible Debt Securities in
accordance with the terms of this Agreement.

         (b)     The Partnership shall apply approximately 99% of the Initial
Partnership Proceeds to purchase (1) a debt instrument of the Company (the
"Initial Company Debenture") in the aggregate principal amount of approximately
$181,926,000 and (2) debt instruments of two wholly owned United States
subsidiaries of the Company totalling approximately $58,216,000 (such debt
instruments collectively referred to as the "Initial Affiliate Debentures").
The Initial Company Debenture and the Initial Affiliate Debentures are
collectively referred to as the "Initial Debentures." The Partnership may
purchase the Initial Debentures only upon receipt of an opinion of the
Independent Financial Advisor to the effect that (i) if such Initial Debentures
were to be rated, at least one Rating Agency would rate all the Initial
Debentures investment grade at the time such Initial Debentures are purchased
by the Partnership, (ii) the Company and each Investment Affiliate which is a
subsidiary of the Company would have been capable of issuing and selling debt
instruments with the same terms and conditions as the applicable Initial
Debentures to unrelated third party investors, (iii) the terms and conditions
of the Initial Debentures taken as a whole are no more favorable to the
relevant Investment Affiliate than could have been obtained by such Investment
Affiliate from unrelated third party investors pursuant to a public offering or
a private placement pursuant to Rule 144A under the Securities Act of 1933 of
such Initial Debentures.  On the Closing Date, the Partnership shall invest at
least 1% of such Initial Partnership Proceeds in Eligible Debt Securities.  The
terms of the Initial Debentures will be as set forth in the Indentures attached
hereto as Exhibits A and B.

         Section 7.2      REINVESTMENT OF PAYMENTS RECEIVED BY THE PARTNERSHIP.

         (a)     The Partnership must at all times invest an amount equal to at
least 1% of the Initial Partnership Proceeds in Eligible Debt Securities.

         (b)     The Partnership may reinvest any payments it receives in
respect of its investments in (i) Eligible Debt Securities without limitation
or (ii) additional Affiliate Investment Instruments but only upon (A) the
acceptance of a written offer setting forth the terms and conditions on which
an Investment Affiliate would be willing to issue an Affiliate Investment
Instrument to the Partnership (an "Investment Offer") and (B) the receipt of an
opinion of the Independent Financial Advisor that the terms of such Affiliate
Investment Instrument set forth in such Investment Offer satisfy the
Reinvestment Criteria (as defined below).





                                       18
<PAGE>   24
         (c)     If the Independent Financial Advisor determines that the terms
of an Affiliate Investment Instrument (as set forth in the Investment Offer) do
not satisfy the Reinvestment Criteria, the Partnership shall be prohibited from
making any investment in such Affiliate Investment Instrument.

         (d)     Each Affiliate Investment Instrument shall satisfy the
following criteria (the "Reinvestment Criteria"): (i) the economic terms of
each Affiliate Investment Instrument shall be no less favorable to the
Partnership than terms that would otherwise be obtainable through a public
offering or private placement under Rule 144A of the Securities Act of 1933 of
securities by the requesting Investment Affiliate and the other terms and
conditions of each Affiliate Reinvestment Instrument are substantially similar
to the terms and conditions of similar securities that are offered to the
public in a public offering or private placement under Rule 144A of the
Securities Act of 1933 of such securities; (ii) the Partnership shall not have
held any Affiliate Investment Instruments of the Investment Affiliate
submitting the Investment Offer within the three-year period ending on the date
of the Investment Offer; (iii) there shall not have been a default on any debt
obligation of the Investment Affiliate submitting the Investment Offer that was
owned by the Partnership; (iv) no dividend arrearages shall have existed on any
equity security of the Investment Affiliate submitting the Investment Offer
that was owned by the Partnership; and (v) the Investment Affiliate submitting
the Investment Offer shall not be deemed to be an investment company by reason
of Section 3(a) or 3(b) of the 1940 Act.

         (e)     Any payments received by the Partnership in respect of its
investments that are not invested in additional Affiliate Investment
Instruments, may be reinvested only in Eligible Debt Securities (subject to
restrictions of applicable law, including the 1940 Act).

         Section 7.3      ASSUMPTION OF OBLIGATIONS AND RELEASE OF INVESTMENT
AFFILIATE.

          The General Partner, on behalf of the Partnership, may without the
approval of the Holders of Partnership Preferred Securities,  release any
Investment Affiliate other than the Company (a "Released Investment Affiliate")
from its obligations under an Affiliate Investment Instrument but only upon (A)
the receipt of a written instrument of assumption evidencing the assumption by
another Investment Affiliate (an "Assuming Investment Affiliate") of all
obligations of the Released Investment Affiliate under such Affiliate
Investment Instrument, (B) the receipt of a written instrument of the Company
evidencing its agreement that its Investment Guarantee will continue to be
applicable to such Affiliate Investment Instrument following the assumption and
release and (C) the receipt of an opinion of the Independent Financial Advisor
that the terms of such Affiliate Investment Instrument would satisfy the
Reinvestment Criteria if such Affiliate Investment Instrument were entered into
de novo by the Assuming Investment Affiliate on the date of such assumption.


                                  ARTICLE VIII

                     BOOKS OF ACCOUNT, RECORDS AND REPORTS

         Section 8.1      BOOKS AND RECORDS.

         (a)     Proper and complete records and books of account of the
Partnership shall be kept by the General Partner, in which shall be entered
fully and accurately all transactions and other matters relative to the
Partnership's investments.  The books and records of the Partnership, together
with a certified copy of this Agreement and of the Certificate, shall at all
times be maintained at the principal office of the General Partner and shall be
open to the inspection and examination of the Partners or their duly authorized
representatives for any proper purpose reasonably related to its Interest
during reasonable business hours.

         (b)     Notwithstanding any other provision of this Agreement to the
contrary, the General Partner may, to the maximum extent permitted by
applicable law, keep confidential from the Partners any information with
respect to the Partnership, the disclosure of which the General Partner
reasonably believes is not in the best interests





                                       19
<PAGE>   25
of the Partnership, or is adverse to the interests of the Partnership, or which
the Partnership or the General Partner is required by law or by an agreement
with any Person to keep confidential.

         (c)     (i) For so long as the Partnership Preferred Securities are
held by the Property Trustee on behalf of the Trust, within one month after the
close of each Fiscal Year, the General Partner shall transmit to each Partner a
statement indicating such Partner's share of each item of Partnership income,
gain, loss, deduction or credit, for United States federal income tax purposes,
for such Fiscal Year.

                 (ii)     In the event that the Partnership Preferred
         Securities are no longer held by the Property Trustee on behalf of the
         Trust, as soon as reasonably possible after the close of the Fiscal
         Year, the General Partner shall transmit to each Partner the statement
         referred to in Section 8.1(c)(i) hereof.

         Section 8.2      ACCOUNTING METHOD.  For both financial and tax
reporting purposes, the books and records of the Partnership shall be kept on
the accrual method of accounting applied on a consistent basis and shall
reflect all Partnership transactions.

         Section 8.3      ANNUAL AUDIT.  As soon as practical after the end of
each Fiscal Year, but not later than 90 days after such end, the financial
statements of the Partnership shall be audited by a firm of independent
certified public accountants selected by the General Partner in accordance with
applicable law.  The cost of such audits will be an expense of the Partnership
and shall be paid by the General Partner.


                                   ARTICLE IX

                              PAYMENT OF EXPENSES

         Section 9.1      PAYMENT OF TRUST EXPENSES AND PARTNERSHIP TAXES.
Since the Trust is being formed solely to facilitate a direct investment in the
Partnership Preferred Securities, the General Partner on behalf of the
Partnership hereby agrees, at any time while the Property Trustee is the Holder
of any Partnership Preferred Securities, to pay all the expenses of the Trust,
including, but not limited to, any taxes, duties, assessments or governmental
charges of whatever nature (other than withholding taxes) imposed on the Trust
by the United States, or any other taxing authority, so that the net amounts
received and retained by the Trust and the Property Trustee after paying such
expenses will be equal to the amounts the Trust and the Property Trustee would
have received had no such costs or expenses been incurred by or imposed on the
Trust.  The General Partner shall be liable for, and shall pay all such
expenses on behalf of the Partnership solely out of its own funds.  In
addition, if the Partnership is required to pay any taxes, duties, assessments
or governmental charges of whatever nature (other than withholding taxes)
imposed by the United States, or any other taxing authority, then, in any case,
the General Partner will pay such taxes, duties, assessments or other
governmental charges on behalf of the Partnership out of its own funds.

         Section 9.2      PAYMENT OF OTHER PARTNERSHIP EXPENSES.  In connection
with the offering, sale and issuance of the Partnership Preferred Securities by
the Partnership, the General Partner shall:

         (a)     pay all costs and expenses of the Partnership (including, but
not limited to, costs and expenses relating to the organization of the
Partnership, the offering, sale and issuance of the Partnership Preferred
Securities (including commissions to the underwriters in connection therewith)
the fees and expenses of the Special Representatives (if any), and the costs
and expenses relating to the operation of the Partnership, including, without
limitation, costs and expenses of accountants, attorneys, statistical or
bookkeeping services, expenses for printing and engraving and computing or
accounting equipment, paying agent(s), registrar(s), transfer agent(s),
duplicating, travel and telephone and other telecommunications expenses; and

         (b)     be primarily and fully liable for any indemnification
obligations arising with respect to this Agreement.

"Beneficiaries"), whether such indebtedness, obligations or liabilities arise
in contract, tort or otherwise (excluding payment obligations of the Company to
Holders of the Partnership Preferred Securities in such Holders' capacities as
Holders of such Partnership Preferred Securities, such obligations being

even if competitive with the activities of the Partnership, shall not be deemed
wrongful or improper.  No Partner or Affiliate thereof shall be obligated to
present any particular investment opportunity to the Partnership even if such
opportunity is of a character that, if presented to the Partnership, could be
taken by the Partnership, and any Partner or Affiliate thereof shall have the
right to take for its own account (individually or as a partner or fiduciary)

         the purposes of the Partnership, as set forth in Section 2.3;

                 (viii)   without the written consent of the Holders of 66-2/3%
         in Liquidation Preference of the Partnership Preferred Securities,
         have an order for relief entered with respect to the Partnership or
         commence a voluntary case under any applicable bankruptcy, insolvency
         or other similar law now or hereafter in effect, or consent to the
         entry of an order for relief in an involuntary case under any such
         law, or consent to the appointment of or taking possession by a
         receiver, trustee or other custodian for all or a substantial part of
         the Partnership's property, or make any assignment for the benefit of
         creditors of the Partnership; or

                 (ix)     borrow money or become liable for the borrowings of
         any third party or to engage in any financial or other trade or
         business.

         Section 11.7     EXCULPATION.

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

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

         Section 11.8     FIDUCIARY DUTY.

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

         (b)     Unless otherwise expressly provided herein, (i) whenever a
conflict of interest exists or arises between Partnership Covered Persons, or
(ii) whether this Agreement or any other agreement contemplated herein or
therein provides that a Partnership Indemnified Person shall act in a manner
that is, or provides terms that are, fair and reasonable to the Partnership or
any Partner, the Partnership 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 Partnership Indemnified Person, the resolution,
action or term so made, taken or provided by the Partnership Indemnified Person
shall not constitute a breach of this Agreement or any other agreement
contemplated herein or of any duty or obligation of the Partnership Indemnified
Person at law or in equity or otherwise.

         (c)     Whenever in this Agreement a Partnership Indemnified Person is
permitted or required to make a decision (i) in its "discretion" or under a
grant of similar authority, the Partnership Indemnified Person shall be





                                       24
<PAGE>   30
entitled to consider such interests and factors as it desires, including its
own interest, and shall have no duty or obligation to give any consideration to
any interest of or factors affecting the Partnership or any other Person, or
(ii) in its "good faith" or under another express standard, the Partnership
Indemnified Person shall act under such express standard and shall not be
subject to any other or different standard imposed by this Agreement or by
applicable law.

         Section 11.9     INDEMNIFICATION.

         (a)     To the fullest extent permitted by applicable law, the
Partnership shall indemnify and hold harmless each Partnership Indemnified
Person from and against any loss, damage or claim incurred by such Partnership
Indemnified Person by reason of any act or omission performed or omitted by
such Partnership Indemnified Person in good faith on behalf of the Partnership
and in a manner such Partnership Indemnified Person reasonably believed to be
within the scope of authority conferred on such Partnership Indemnified Person
by this Agreement, except that no Partnership Indemnified Person shall be
entitled to be indemnified in respect of any loss, damage or claim incurred by
such Partnership Indemnified Person by reason of gross negligence or willful
misconduct with respect to such acts or omissions; provided, however, that any
indemnity under this Section 11.9 shall be provided out of and to the extent of
Partnership assets only, and no Partnership Covered Person shall have any
personal liability on account thereof.

         (b)     To the fullest extent permitted by applicable law, expenses
(including legal fees) incurred by a Partnership Indemnified Person in
defending any claim, demand, action, suit or proceeding shall, from time to
time, be advanced by the Partnership prior to the final disposition of such
claim, demand, action, suit or proceeding upon receipt by the Partnership of an
undertaking by or on behalf of the Partnership Indemnified Person to repay such
amount if it shall be determined that the Partnership Indemnified Person is not
entitled to be indemnified as authorized in Section 11.9(a).

         Section 11.10    TAX MATTERS

         (a)     For purposes of section 6231(a)(7) of the Code, the "Tax
Matters Partner" shall be the Company as long as it remains the general partner
of the Partnership.  The Tax Matters Partner shall keep the Limited Partners
fully informed of any inquiry, examination or proceeding.

         (b)     Neither the Partnership, nor the Tax Matters Partner on behalf
of the Partnership, shall make an election under section 754 of the Code.

         (c)     The General Partner and the Partnership Preferred Security
Holders acknowledge that they intend, for United States federal income tax
purposes, that the Partnership shall be treated as a "partnership" (other than
a publicly traded partnership taxable as a corporation) and that the General
Partner and the Partnership Preferred Security Holders shall be treated as
"partners" of the Partnership.

         (d)     The General Partner shall retain, at the expense of the
Partnership and at its sole discretion, a nationally recognized firm of
certified public accountants which shall prepare all United States federal,
state, local or other tax and information returns of the Partnership, as
required by law, and the Schedule K-1's or any successor or similar forms or
schedules.

         Section 11.11    CONSOLIDATION, MERGER OR SALE OF ASSETS.  The
Partnership may not consolidate, amalgamate, merge with or into, or be replaced
by, or convey, transfer or lease its properties and assets substantially as an
entirety to, any corporation or other body, except as permitted pursuant to
this Section 11.11.  The Partnership may, without the consent of the Holders of
the Partnership Preferred Securities, consolidate, amalgamate, merge with or
into, or be replaced by a limited partnership, limited liability company or
trust organized as such under the laws of any state of the United States of
America, provided that (i) such successor entity either (x) expressly assumes
all of the obligations of the Partnership under the Partnership Preferred
Securities or (y) substitutes for the Partnership Preferred Securities other
securities having substantially the same terms





                                       25
<PAGE>   31
as the Partnership Preferred Securities (the "Partnership Successor
Securities") so long as the Partnership Successor Securities are not junior to
any other equity securities of the successor entity, with respect to
participation in the profits and distributions, and in the assets, of the
successor entity, (ii) the Investment Affiliates expressly acknowledge such
successor entity as the holder of the Affiliate Investment Instruments, (iii)
the Partnership Preferred Securities continue to be or any Partnership
Successor Securities are or will be listed, upon notification of issuance, on
any national securities exchange or other organization on which the Partnership
Preferred Securities, if so listed, are then listed, (iv) such merger,
consolidation, amalgamation or replacement does not cause the Trust Preferred
Securities (or, in the event that the Trust is liquidated in connection with a
Trust Special Event, the Partnership Preferred Securities (including any
Partnership Successor Securities)) to be downgraded by any nationally
recognized statistical securities rating organization, (v) such merger,
consolidation, amalgamation or replacement does not adversely affect the
powers, preferences and other special rights of the holders of the Trust
Preferred Securities or the Holders of the Partnership Preferred Securities
(including any Partnership Successor Securities)) in any material respect
(other than, in the case of the Partnership Preferred Securities, with respect
to any dilution of the Holders' interest in the new resulting entity), (vi)
such successor entity has a purpose substantially identical to that of the
Partnership, (vii) prior to such merger, consolidation, amalgamation or
replacement, the Company has received an opinion of nationally recognized
independent counsel to the Partnership experienced in such matters to the
effect that (A) such successor entity will be treated as a "partnership" for
United States federal income tax purposes and not as an association or a
publicly traded partnership taxable as a corporation, (B) such merger,
consolidation, amalgamation or replacement will not cause the Trust to be
classified as an association or a publicly traded partnership taxable as a
corporation for United States federal income tax purposes, (C) following such
merger, consolidation, amalgamation or replacement, the Company and such
successor entity will be in compliance with the 1940 Act without registering
thereunder as an investment company, and (D) such merger, consolidation,
amalgamation or replacement will not adversely affect the limited liability of
the Holders of the Partnership Preferred Securities and (viii) the Company
guarantees the obligations of such successor entity under the Partnership
Successor Securities at least to the extent provided by the Partnership
Guarantee.

                                  ARTICLE XII

                       TRANSFERS OF INTERESTS BY PARTNERS

         Section 12.1     TRANSFER OF INTERESTS.

         (a)     Partnership Preferred Securities shall be freely transferable
by a Holder.

         (b)     Except as provided in the next sentence, the General Partner
may not assign or transfer its Interest in the Partnership in whole or in part
unless, prior to such assignment or transfer, the General Partner has obtained
the consent of the Holders of not less than 66-2/3% in Liquidation Preference
of the Partnership Preferred Securities.  The General Partner may assign or
transfer its Interest in the Partnership without such consent only to an entity
that is the survivor of a merger or consolidation of the General Partner in a
transaction that meets the requirements of Section 11.11 and only if prior to
such assignment or transfer the Company has received an opinion of nationally
recognized independent tax counsel to the Partnership experienced in such
matters to the effect that after such assignment or transfer the Partnership
will continue to be treated as a partnership for United States federal income
tax purposes and will not be treated as an association or a publicly traded
partnership taxable as a corporation.  "Permitted Successor" shall mean an
entity that is an assignee or transferee of the Interest of the General Partner
as permitted by this Section 12.1(b).  The admission of a Permitted Successor
as a general partner of the Partnership shall be effective upon the filing of
an amendment to the Certificate with the Secretary of State of the State of
Delaware which indicates that the Permitted Successor has been admitted as a
general partner of the Partnership.  If the General Partner assigns its entire
Interest, the General Partner shall cease to be a general partner of the
Partnership simultaneously with the admission of the Permitted Successor as a
general partner of the Partnership.  Any such Permitted Successor is hereby
authorized to and shall continue the business of the Partnership without
dissolution.





                                       26
<PAGE>   32
         (c)     Except as provided above, no Interest shall be transferred, in
whole or in part, except in accordance with the terms and conditions set forth
in this Agreement.  Any transfer or purported transfer of any Interest not made
in accordance with this Agreement shall be null and void.

         Section 12.2     TRANSFER OF L.P. CERTIFICATES.  The General Partner
shall provide for the registration of L.P.  Certificates and of transfers of
L.P. Certificates.  Upon surrender for registration of transfer of any L.P.
Certificate, the General Partner shall cause one or more new L.P. Certificates
to be issued in the name of the designated transferee or transferees.  Every
L.P. Certificate surrendered for registration of transfer shall be accompanied
by a written instrument of transfer in form satisfactory to the General Partner
duly executed by the Partnership Preferred Security Holder or his or her
attorney duly authorized in writing.  Each L.P. Certificate surrendered for
registration of transfer shall be canceled by the General Partner.  A
transferee of an L.P. Certificate shall be admitted to the Partnership as a
Limited Partner, shall become bound by this Agreement and shall be entitled to
the rights and subject to the obligations of a Partnership Preferred Security
Holder hereunder upon the receipt by the transferee of an L.P. Certificate,
which receipt shall be deemed to constitute a request by such transferee that
the books and records of the Partnership reflect such transferee's admission as
a limited partner.  The transferor of an L.P. Certificate, in whole, shall
cease to be a Limited Partner at the time that the transferee of such L.P.
Certificate is admitted to the Partnership as a Limited Partner in accordance
with this Section 12.2.

         Section 12.3     DEFINITIVE L.P. CERTIFICATES; PERSONS DEEMED
PARTNERSHIP PREFERRED SECURITY HOLDERS.

         (a)     Unless and until the Partnership issues a global L.P.
Certificate pursuant to Section 12.4(a), the Partnership shall only issue
definitive L.P. Certificates to the Partnership Preferred Security Holders.

         (b)     The Partnership may treat the Person in whose name any L.P.
Certificate shall be registered on the books and records of the Partnership as
the sole holder of such L.P. Certificate and of the Partnership Preferred
Securities represented by such L.P. Certificate for purposes of receiving
Distributions and for all other purposes whatsoever (including without
limitation, tax returns and information reports) and, accordingly, shall not be
bound to recognize any equitable or other claim to or interest in such L.P.
Certificate or in the Partnership Preferred Securities represented by such L.P.
Certificate on the part of any other Person, whether or not the Partnership
shall have actual or other notice thereof.

         Section 12.4     BOOK-ENTRY PROVISIONS.

         (a)     General.  The provisions of this Section 12.4 shall apply only
in the event that the Partnership Preferred Securities are distributed to the
Holders of Trust Securities in connection with the involuntary or voluntary
dissolution, winding-up or liquidation of the Trust as a result of the
occurrence of a Trust Special Event.  Upon the occurrence of such event, a
global L.P. Certificate representing the Book-Entry Interests shall be
delivered to DTC, the initial Clearing Agency, by, or on behalf of, the
Partnership and any previously issued and still outstanding definitive L.P.
Certificates shall be of no further force and effect.  The global L.P.
Certificate shall initially be registered on the books and records of the
Partnership in the name of Cede & Co., the nominee of DTC, and no Holder of a
Partnership Preferred Security will receive a new definitive L.P. Certificate
representing such Holder's interests in such L.P.  Certificate, except as
provided in Section 12.4(c).  In connection with the involuntary or voluntary
dissolution, winding-up or liquidation of the Trust as a result of the
occurrence of a Trust Special Event, Cede & Co., the nominee of DTC, shall
automatically be admitted to the Partnership as a Limited Partner.  Receipt of
the global L.P. Certificate shall be deemed to constitute a request by Cede &
Co., the nominee of DTC, that the books and records of the Partnership reflect
its admission as a Limited Partner.  Unless and until new definitive, fully
registered L.P. Certificates (the "Definitive L.P. Certificates") have been
issued to the Partnership Preferred Security Owners pursuant to Section
12.4(c):

                 (i)      The provisions of this Section shall be in full force
         and effect;





                                       27
<PAGE>   33
                 (ii)     The Partnership, the General Partner and any Special
         Representative shall be entitled to deal with the Clearing Agency for
         all purposes of this Agreement (including the payment of
         Distributions, Redemption Price and liquidation proceeds on the L.P.
         Certificates and receiving approvals, votes or consents hereunder) as
         the Partnership Preferred Security Holder and the sole holder of the
         L.P. Certificates and shall have no obligation to the Partnership
         Preferred Security Owners;

                 (iii)    None of the Partnership, the Trust, the General
         Partner, any Special Representative or any agents of any of the
         foregoing shall have any liability or responsibility for any aspect of
         the records relating to or payments made on account of beneficial
         ownership interests in a global L.P. Certificate for such beneficial
         ownership interests or for maintaining, supervising or reviewing any
         records relating to such beneficial ownership interests; and

                 (iv)     Except as provided in Section 12.4(c) below, the
         Partnership Preferred Security Owners will not be entitled to receive
         physical delivery of the Partnership Preferred Securities in
         definitive form and will not be considered Holders thereof for any
         purpose under this Agreement, and no global L.P. Certificate
         representing Partnership Preferred Securities shall be exchangeable,
         except for another global L.P. Certificate of like denomination and
         tenor to be registered in the name of DTC or Cede & Co., or to a
         successor Depositary or its nominee.  Accordingly, each Partnership
         Preferred Security Owner must rely on the procedures of DTC or if such
         person is not a Participant, on the procedures of the Participant
         through which such person owns its interest to exercise any rights of
         a Holder under the Agreement.

         (b)     NOTICES TO CLEARING AGENCY.  Whenever a notice or other
communication to the Partnership Preferred Security Holders is required under
this Agreement, unless and until Definitive L.P. Certificates shall have been
issued to the Partnership Preferred Security Owners pursuant to Section
12.4(c), the General Partner and any Special Representative shall give all such
notices and communications specified herein to be given to the Partnership
Preferred Security Holders to the Clearing Agency, and shall have no
obligations to the Partnership Preferred Security Owners.

         (c)     DEFINITIVE L.P. CERTIFICATES.  Definitive L.P. Certificates
shall be prepared by the Partnership and exchangeable for the global L.P.
Certificate or L.P. Certificates if and only if (i) the Depositary notifies the
Company that it is unwilling or unable to continue its services as a securities
depositary and no successor depositary shall have been appointed, (ii) the
Depositary, at any time, ceases to be a clearing agency registered under the
Exchange Act at such time as the Depositary is required to be so registered to
act as such depositary and no successor depositary shall have been appointed,
or (iii) the Company, in its sole discretion, determines that such global L.P.
Certificate shall be so exchangeable.  Upon surrender of the global L.P.
Certificate or L.P. Certificates representing the Book- Entry Interests by the
Clearing Agency, accompanied by registration instructions, the General Partner
shall cause Definitive L.P. Certificates to be delivered to Partnership
Preferred Security Owners in accordance with the instructions of the Clearing
Agency.  Neither the General Partner nor the Partnership shall be liable for
any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions.  Any Person receiving a
Definitive L.P. Certificate in accordance with this Section 12.4 shall be
admitted to the Partnership as a Limited Partner upon receipt of such
Definitive L.P. Certificate and shall be registered on the books and records of
the Partnership as a Partnership Preferred Security Holder.  The Clearing
Agency or the nominee of the Clearing Agency, as the case may be, shall cease
to be a Limited Partner under this Section 12.4(c) at the time that at least
one additional Person is admitted to the Partnership as a Limited Partner in
accordance herewith.  The Definitive L.P. Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as may be
required by any national securities exchange on which Partnership Preferred
Securities may be listed and is reasonably acceptable to the General Partner,
as evidenced by its execution thereof.

         Section 12.5     REGISTRAR, TRANSFER AGENT AND PAYING AGENT.

         (a)     The General Partner will act as Registrar, Transfer Agent and
Paying Agent for the Partnership Preferred Securities for so long as the
Partnership Preferred Securities are held by the Trust or, if the Trust is
liquidated in connection with a Trust Special Event, for so long as the
Partnership Preferred Securities remain in book- entry only form.

         (b)     Except in such case where the General Partner shall act as
Registrar or Paying Agent pursuant to Section 12.5(a) hereof, the Partnership
shall maintain in the Borough of Manhattan, City of New York, State of New York
(i) an office or agency where Partnership Preferred Securities may be presented
for registration of transfer or for exchange ("Registrar") and (ii) an office
or agency where Partnership Preferred Securities may be presented for payment
("Paying Agent").  The Registrar shall keep a register of the Partnership
Preferred Securities and of their transfer and exchange.  The Partnership may
appoint the Registrar and the Paying Agent and may appoint one or more
co-registrars and one or more additional paying agents in such other locations
as it shall determine.  The term "Paying Agent" includes any additional paying
agent.  The Partnership may change any Paying Agent, Registrar or co-registrar
without prior notice to any Holder.  If the Partnership fails to appoint or
maintain another entity as Registrar or Paying Agent, the General Partner shall
act as such.

         (c)     Registration of transfers of Partnership Preferred Securities
shall be effected without charge by or on behalf of the Partnership, but upon
payment (with the giving of such indemnity as the Partnership or the General
Partner may require) in respect of any tax or other governmental charges that
may be imposed.

         (d)     The Partnership will not be required to register or cause to
be registered the transfer of Partnership Preferred Securities after such
Partnership Preferred Securities have been called for redemption.


                                  ARTICLE XIII

                            WITHDRAWAL, DISSOLUTION;
                     LIQUIDATION AND DISTRIBUTION OF ASSETS

         Section 13.1     WITHDRAWAL OF PARTNERS.  The General Partner shall
not at any time retire or withdraw from the Partnership except as otherwise
permitted hereunder.  If the General Partner retires or withdraws in
contravention of this Section 13.1, it shall indemnify, defend and hold
harmless the Partnership and the other Partners from and against any losses,
expenses, judgments, fines, settlements or damages suffered or incurred by the
Partnership or such other Partners arising out of or resulting from such
retirement or withdrawal.

         Section 13.2     DISSOLUTION OF THE PARTNERSHIP.

         (a)     The Partnership shall not be dissolved by the admission of
Partners in accordance with the terms of this Agreement.  The death,
withdrawal, bankruptcy or dissolution of a Limited Partner, or the occurrence
of any other event which terminates the Interest of a Limited Partner in the
Partnership, shall not, in and of itself, cause the Partnership to be dissolved
and its affairs wound up.  To the fullest extent permitted by applicable law,
upon the occurrence of any such event, the General Partner may, without any
further act, vote on approval of any Partner, admit any Person to the
Partnership as an additional or substitute limited partner in the Partnership,
which admission shall be effective as of the date of the occurrence of such
event, and the business of the Partnership shall be continued without
dissolution.

         (b)     The Partnership shall be dissolved and its affairs shall be
wound up upon the earliest to occur of any of the following events:

                 (i)      upon the bankruptcy, insolvency or dissolution of the
         General Partner;





                                       29
<PAGE>   35
                 (ii)     upon the assignment by the General Partner of its
         entire interest in the Partnership when the assignee is not admitted
         to the Partnership as a general partner of the Partnership in
         accordance with this Agreement, or the filing of a certificate of
         dissolution or its equivalent with respect to the General Partner, or
         the revocation of the General Partner's charter and the expiration of
         90 days after the date of notice to the General Partner of revocation
         without a reinstatement of its charter, or if any other event occurs
         that causes the General Partner to cease to be a general partner of
         the Partnership under the Partnership Act, unless the business of the
         Partnership is continued in accordance with the Partnership Act;

                 (iii)    the Partnership has redeemed or otherwise purchased
         all of the Partnership Preferred Securities;

                 (iv)     the entry of a decree of judicial dissolution under
         Section 17-802 of the Act; or

                 (v)      the written consent of all Partners.

         (c)     Upon dissolution of the Partnership, the Liquidator shall
promptly notify the Partners of such dissolution.

         Section 13.3     LIQUIDATION.

         (a)     In the event of the dissolution of the Partnership for any
reason, the General Partner (or, if the Partnership is dissolved pursuant to
Section 13.2(b)(i) or (ii), then a liquidating agent appointed by Holders of
not less than 66 2/3% in Liquidation Preference of the Partnership Preferred
Securities (the General Partner or such Person so appointed is hereinafter
referred to as the "Liquidator")) shall commence to wind up the affairs of the
Partnership and to liquidate the Partnership's assets; provided, however, that
a reasonable time shall be allowed for the orderly liquidation of the assets of
the Partnership and the satisfaction of liabilities to creditors so as to
enable the Partners to minimize the normal losses attendant upon liquidation.
The Partners shall continue to share all income, losses and distributions
during the period of liquidation in accordance with Articles IV and V.  Subject
to the provisions of this Article XIII, the Liquidator shall have full right
and unlimited discretion to determine the time, manner and terms of any sale or
sales of Partnership property pursuant to such liquidation, giving due regard
to the activity and condition of the relevant market and general financial and
economic conditions.

         (b)     The Liquidator shall have all of the rights and powers with
respect to the assets and liabilities of the Partnership in connection with the
liquidation and termination of the Partnership that the General Partner would
have with respect to the assets and liabilities of the Partnership during the
term of the Partnership, and the Liquidator is hereby expressly authorized and
empowered to execute any and all documents necessary or desirable to effectuate
the liquidation and termination of the Partnership and the transfer of any
assets.

         (c)     Notwithstanding the foregoing, a Liquidator that is not a
General Partner shall not, by virtue of acting in such capacity, be deemed a
Partner in this Partnership and shall not have any of the economic interests in
the Partnership of a Partner; and such Liquidator may be compensated for its
services to the Partnership at normal customary and competitive rates for its

liquidation shall be applied in the following order of priority (and without
regard to the non-mandatory provisions of Section 17-804 of the Act):

                 (i)      first, to creditors of the Partnership, including
         Partners who are creditors, to the extent otherwise permitted by law,
         in satisfaction of the liabilities of the Partnership (whether by

         other than liabilities for distributions (including Distributions) to
         Partners;

                 (ii)     second, following any allocations required under
         Section 4.2(e) of the Agreement, to the Limited Partners, an amount
         equal to the aggregate liquidation preference of their Partnership
         Preferred Securities, plus the amount of Distributions (including any
         Compounded Distributions) that are accrued and unpaid as of the date
         of such liquidating distribution; and

                 (iii)    thereafter, to the General Partner.

         Section 13.5     RIGHTS OF LIMITED PARTNERS.  Each Limited Partner
shall look solely to the assets of the Partnership for all distributions with
respect to the Partnership and such Partner's capital contribution (including
returns thereof), and such Partner's share of profits or losses thereof, and
shall have no recourse therefor (upon dissolution or otherwise) against the
General Partner, except under the Partnership Guarantee.  No Partner shall have
any right to demand or receive property other than cash upon dissolution and
termination of the Partnership.

         Section 13.6     TERMINATION.  The Partnership shall terminate when
all of the assets of the Partnership shall have been disposed of and the assets
shall have been distributed as provided in Section 13.4 and the Liquidator has
executed and caused to be filed a certificate of cancellation of the
Partnership.

                            AMENDMENTS AND MEETINGS

         Section 14.1     AMENDMENTS.  Except as provided by Section 3.3(b) and
Section 6.2(i), this Agreement may be amended by, and only by, a written
instrument executed by the General Partner without the consent of any Limited
Partner; provided, however, that no amendment shall be made, and any such
purported amendment shall be void and ineffective, to the extent the result
thereof would be to (A) cause the Partnership to be treated for United States
federal income tax purposes as an association or a publicly traded partnership
taxable as a corporation, (B) require the Partnership to register under the
1940 Act or (C) materially adversely affect the rights, privileges or
preferences of the Partnership Preferred Securities.  Notwithstanding any
provision to the contrary, in the event of (i) a liquidation of the Trust for
any reason or (ii) any other distribution which effectively causes Partnership
Preferred Securities to be distributed to Holders of Trust Preferred
Securities, the General Partner may amend this Agreement without the consent of
the Limited Partners to provide for (A) orderly dissemination, purchase, sale,
exchange and replacement of such Partnership Preferred Securities, (B) all
other matters to the extent required by or desirable under then applicable law
and (C) such other matters reasonably incidental or related thereto; provided,
however, that no such amendment may materially adversely affect the rights,
privileges, or preferences of the Partnership Preferred Securities without the
consent of a majority in interest of the Partners so affected.

         Section 14.2     AMENDMENT OF CERTIFICATE.  In the event this
Agreement shall be amended pursuant to Section 14.1, the General Partner shall
amend the Certificate to reflect such change if it deems such amendment of the
Certificate to be necessary or appropriate.

         Section 14.3     MEETINGS OF PARTNERS.

         (a)     Meetings of the Limited Partners who are Holders may be called
at any time by the General Partner to consider and act on any matter on which
Limited Partners are entitled to act under the terms of this Agreement or the
Act.  The General Partner shall call a meeting of Holders if directed to do so
by Holders of no less than 10% in Liquidation Preference as permitted by this
Agreement.  Such direction shall be given by delivering to the General Partner
a request in writing stating that the signing Limited Partners desire to call a
meeting and indicating the general or specific purpose for which the meeting is
to be called.  Any Limited Partners calling a meeting shall specify in writing
the L.P. Certificates held by the Limited Partners exercising the right to call
a meeting and only those specified Interests shall be counted for purposes of
determining whether the required percentage 





                                       31
<PAGE>   37
set forth in the second sentence of this paragraph has been met. Except to the
extent otherwise provided in this Agreement, the following provisions shall
apply to meetings of Partners.
        
         (b)     Notice of any such meeting shall be given to all Limited
Partners having a right to vote thereat not less than seven Business Days nor
more than 60 days prior to the date of such meeting.  Each such notice shall
set forth the date, time and place of the meeting, a description of any matter
on which Holders are entitled to vote and instructions for the delivery of
proxies or written consents.

         (c)     Any action that may be taken at a meeting of the Limited
Partners may be taken without a meeting if a consent in writing setting forth
the action so taken is signed by Limited Partners owning not less than the
minimum Interests that would be necessary to authorize or take such action at a
meeting in which all Limited Partners 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 Limited Partners entitled to vote who have not consented
in writing.  The General Partner may provide that any written ballot submitted
to the Limited Partners for the purpose of taking any action without a meeting
shall be returned to the Partnership within a specified time.

         (d)     Each Partner may authorize any Person to act for it by proxy
on all matters as to which a Partner is entitled to participate, including
waiving notice of any meeting, or voting or participating at a meeting.  Every
proxy must be signed by the Partner or its attorney-in-fact.  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
Partner executing it.  Except as otherwise provided herein, or pursuant to
Section 14.3(f), 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 Partnership were a Delaware corporation and the Limited Partners were
stockholders of a Delaware corporation.

         (e)     Each meeting of Partners shall be conducted by the General
Partner or by such other Person that the General Partner may designate.

         (f)     The General Partner may establish all other reasonable
procedures relating to meetings of Limited Partners or the giving of written
consents, in addition to those expressly provided, including notice of time,
place or purpose of any meeting at which any matter is to be voted on by any
Partners, 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.

                         [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Partnership Preferred Security will be
fixed at a rate per annum of 8.30% of the stated liquidation amount of $25 per
Partnership Preferred Security.  Distributions not paid on the scheduled
payment date will accumulate and compound quarterly (to the extent permitted by
applicable law) at the rate of 8.30 % per annum.  The term "Distributions" as
used herein shall mean ordinary cumulative distributions in respect of each
Fiscal Period together with any such Compounded Distributions.  Distributions
on the Partnership Preferred Securities will only be made to the extent that
the Partnership has funds legally available for the payment of such
distributions.  Amounts available to the Partnership for distribution to the
holders of the Partnership Preferred Securities will be limited to payments
received by the Partnership from the Company and certain wholly owned
subsidiaries on the Affiliate Investment Instruments or from the Company on the
Partnership Guarantee or on the Eligible Debt Securities.  Distributions on the
Partnership Preferred Securities will be paid only if, as and when declared in
the sole discretion of the Company, as the General Partner of the Partnership.
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 on the basis of the actual number of days elapsed in a 90-day quarter.

         Except as otherwise described herein, distributions on the Partnership
Preferred Securities will be cumulative, will accrue from the date of initial
issuance and will be payable quarterly in arrears, on March 31, June 30,
September 30 and December 31 of each year, commencing on December 31, 1996, if,
as and when declared by the General Partner in its sole discretion.  If the
Trust Preferred Securities (or, if the Trust is liquidated, the Partnership
Preferred Securities) are in book-entry only form, Distributions will be
payable to the Holders of record of Partnership Preferred Securities as they
appear on the books and records of the Partnership on the relevant record
dates, which will be one Business Day prior to the relevant payment dates.  If
the Trust or the Property Trustee is the Holder of the Partnership Preferred
Securities, all distributions of cash shall be made by wire transfer of same
day funds to such Holder by 10:00 a.m., New York City time, on the applicable
Distribution Payment Date.  Distributions payable on any Partnership Preferred
Securities that are not punctually paid on any Distribution Payment Date will
cease to be payable to the Person in whose name such Partnership Preferred
Securities are registered on the relevant record date, and such Distribution
will instead be payable to the Person in whose name such Partnership Preferred
Securities are registered on the record date for payment of such defaulted or
accrued Distribution.  If the Trust Preferred Securities (or, if the Trust is
liquidated, the Partnership Preferred Securities) are not in book-entry only
form, the relevant record dates shall be the 15th day of the month of the
relevant payment dates.  In the event that any date on which distributions are
payable is not a Business Day, payment of such Distribution shall be made on
the next succeeding day which is a Business Day (without any interest or other
payment in respect of any such delay) except that, if such Business Day falls
in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day (without any reduction in interest or other
amounts in respect of any such early payment).

         The Partnership Preferred Securities shall be redeemable as provided
in the Partnership Agreement.

Holders (as defined herein) from time to time of the Trust Preferred Securities
(as defined herein) of Enron Capital Trust I, a Delaware statutory business
trust (the "Issuer").

         WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the
"Declaration"), dated as of November 18, 1996, among the trustees of the Issuer
named therein, Enron Corp., as sponsor, and the holders from time to time of

         WHEREAS, as incentive for the Holders to purchase the Trust Preferred

the extent set forth in this Trust Preferred Securities Guarantee, to pay to
the Holders of the Trust Preferred Securities the Guarantee Payments (as

Common Securities to receive Guarantee Payments under the Trust Common
Securities Guarantee are subordinated to the rights of Holders of Trust
Preferred Securities to receive Guarantee Payments under this Trust Preferred
Securities Guarantee.

         NOW, THEREFORE, in consideration of the purchase by each Holder of

                          Trustee shall have reasonable grounds for believing
                          that the repayment of such funds or liability is not
                          reasonably assured to it under the terms of this
                          Trust Preferred Securities Guarantee or indemnity,

                          expenses (including attorneys' fees and expenses and
                          the expenses of the Preferred Guarantee Trustee's
                          agents, nominees or custodians) and liabilities that

                          request or direction, including such reasonable
                          advances as may be requested by the Trust Preferred
                          Guarantee Trustee; provided that, nothing contained
                          in this Section 3.2(a)(vi) shall be taken to relieve
                          the Trust Preferred Guarantee Trustee, upon the
                          occurrence of an Event of Default, of its obligation

                          this Trust Preferred Securities Guarantee.

                 (vii)    The Trust Preferred Guarantee Trustee shall not be
                          bound to make any investigation into the facts or
                          matters stated in any resolution, certificate,
                          statement, instrument, opinion, report, notice,

                          or document, but the Trust Preferred Guarantee
                          Trustee, in its discretion, may make such further
                          inquiry or investigation into such facts or matters
                          as it may see fit.

                 (viii)   The Trust Preferred Guarantee Trustee may execute any
                          of the trusts or powers hereunder or perform any

                          Trust Preferred Guarantee Trustee shall not be
                          responsible for any misconduct or negligence on the
                          part of any agent or attorney appointed with due care
                          by it hereunder.

                 (ix)     Any action taken by the Trust Preferred Guarantee
                          Trustee or its agents hereunder shall bind the
                          Holders of the Trust Preferred Securities, and the
                          signature of the Trust Preferred Guarantee Trustee or
                          its agents alone shall be sufficient and effective to
                          perform any such action.  No third party shall be
                          required to inquire as to the authority of the Trust
                          Preferred Guarantee Trustee to so act or as to its
                          compliance with any of the terms and provisions of
                          this Trust Preferred Securities Guarantee, both of
                          which shall be conclusively evidenced by the Trust
                          Preferred Guarantee Trustee or its agent taking such
                          action.

                 (x)      Whenever in the administration of this Trust
                          Preferred Securities Guarantee the Trust Preferred
                          Guarantee Trustee shall deem it desirable to receive
                          instructions with respect to enforcing any remedy or
                          right or taking any other action hereunder, the Trust
                          Preferred Guarantee Trustee (i) may request
                          instructions from the Holders of a Majority in
                          liquidation amount of the Trust Preferred Securities,
                          (ii) may refrain from enforcing such remedy or right
                          or taking such other action until such instructions
                          are received, and (iii) shall be protected in
                          conclusively relying on or acting in accordance with
                          such instructions.

                 (xi)     The Trust Preferred Guarantee Trustee shall not be
                          liable for any action taken, suffered, or omitted to
                          be taken by it in good faith and reasonably believed
                          by it to be authorized or within the discretion or
                          rights or powers conferred upon it by this Trust
                          Preferred Securities Guarantee.

         (b)     No provision of this Trust Preferred Securities Guarantee
                 shall be deemed to impose any duty or obligation on the Trust
                 Preferred Guarantee Trustee to perform any act or acts or
                 exercise any right, power, duty or obligation conferred or
                 imposed on it in any jurisdiction in which it shall be
                 illegal, or in which the Trust Preferred Guarantee Trustee
                 shall be unqualified or incompetent in accordance with
                 applicable law, to perform any such act or acts or to exercise
                 any such right, power, duty or obligation.  No permissive
                 power or authority available to the Trust Preferred Guarantee
                 Trustee shall be construed to be a duty.

                 prescribing such notice, if any, as it may deem proper,
                 appoint a Successor Trust Preferred Guarantee Trustee.

                 sum payable that results from the extension of any interest
                 payment period on the Partnership Preferred Securities or any
                 extension of the maturity date of the Partnership Preferred
                 Securities permitted by the Partnership Agreement);

         (c)     any failure, omission, delay or lack of diligence on the part
                 of the Holders to enforce, assert or exercise any right,
                 privilege, power or remedy conferred on the Holders pursuant
                 to the terms of the Trust Preferred Securities, or any action
                 on the part of the Issuer granting indulgence or extension of
                 any kind;

         (d)     the voluntary or involuntary liquidation, dissolution, sale of
                 any collateral, receivership, insolvency, bankruptcy,
                 assignment for the benefit of creditors, reorganization,
                 arrangement, composition or readjustment of debt of, or other
                 similar proceedings affecting, the Issuer or any of the assets
                 of the Issuer;

         (e)     any invalidity of, or defect or deficiency in, the Trust
                 Preferred Securities;

         (f)     the settlement or compromise of any obligation guaranteed
                 hereby or hereby incurred; or

         (g)     any other circumstance whatsoever that might otherwise
                 constitute a legal or equitable discharge or defense of a
                 guarantor, it being the intent of this Section 5.3 that the
                 obligations of the Guarantor hereunder shall be absolute and
                 unconditional under any and all circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4      Rights of Holders

         (a)     The Holders of a Majority in liquidation amount of the Trust
                 Preferred Securities have the right to direct the time, method
                 and place of conducting of any proceeding for any remedy
                 available to the Trust Preferred Guarantee Trustee in respect
                 of this Trust Preferred Securities Guarantee or exercising any
                 trust or power conferred upon the Trust Preferred Guarantee
                 Trustee under this Trust Preferred Securities Guarantee.

         (b)     If the Trust Preferred Guarantee Trustee fails to enforce its
                 rights under the Trust Preferred Securities Guarantee after a
                 Holder of Trust Preferred Securities has made a written
                 request, such Holder of Trust Preferred Securities may
                 institute a legal proceeding directly against the Guarantor to
                 enforce the Trust Preferred Guarantee Trustee's rights under
                 this Trust Preferred Securities Guarantee, without first
                 instituting a legal proceeding against the Issuer, the Trust
                 Preferred Guarantee Trustee or any other person or entity.
                 Notwithstanding the foregoing, if the Guarantor has failed to
                 make a guarantee payment, a Holder of Trust Preferred
                 Securities may directly institute a proceeding in such
                 Holder's own name against the Guarantor for enforcement of the
                 Trust Preferred Securities Guarantee for such payment.  The
                 Guarantor waives any right or remedy to require that any
                 action be brought first against the Issuer or any other person
                 or entity before proceeding directly against the Guarantor.

SECTION 5.5      Guarantee of Payment

         This Trust Preferred Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6      Subrogation

         The Guarantor shall be subrogated to all (if any) rights of the
Holders of Trust Preferred Securities against the Issuer in respect of any
amounts paid to such Holders by the Guarantor under this Trust Preferred
Securities





                                       11
<PAGE>   15
Guarantee; provided, however, that the Guarantor shall not (except to the
extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under
this Trust Preferred Securities Guarantee, if, at the time of any such payment,
any amounts are due and unpaid under this Trust Preferred Securities Guarantee.
If any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

SECTION 5.7      Independent Obligations

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Trust
Preferred Securities, and that the Guarantor shall be liable as principal and
as debtor hereunder to make Guarantee Payments pursuant to the terms of this
Trust Preferred Securities Guarantee notwithstanding the occurrence of any
event referred to in subsections (a) through (g), inclusive, of Section 5.3
hereof.


                                   ARTICLE VI
                   LIMITATION OF TRANSACTIONS; SUBORDINATION

SECTION 6.1      Limitation of Transactions

         So long as any Trust Preferred Securities remain outstanding, if for
any distribution period, (a) full distributions on a cumulative basis on any
Trust Preferred Securities have not been paid or declared and set apart for
payment, (b) an Investment Event of Default by any Investment Affiliate in
respect of any Affiliate Investment Instrument has occurred and is continuing,
or (c) the Company is in default of its obligations under the Trust Preferred
Securities Guarantee, the Trust Common Securities Guarantee, the Partnership
Guarantee or any Investment Guarantee, then, during such period (i) the Company
shall not declare or pay dividends on, make distributions with respect to, or
redeem, purchase or acquire, or make a liquidation payment with respect to any
of its capital stock (except for dividends or distributions in shares of its
common stock and exchanges of common stock of one class for common stock of
another class), (ii) the Company shall not make any payment or cause any
payment to be made that would result in and shall take such action as shall be
necessary to prevent, the payment of  dividends on, any distribution with
respect to, any redemption, purchase or other acquisition of, or any
liquidation payment with respect to, any Comparable Equity Interest, and (iii)
the Company shall not make any guarantee payments with respect to the
foregoing.

SECTION 6.2      Ranking

         This Trust Preferred Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank (i) subordinate and junior in right
of payment to all other liabilities of the Guarantor, including, without
limitation, the fees, charges, expenses and indemnities due to the Property
Trustee or the Delaware Trustee in respect of the Declaration of Trust, the
Trust Preferred Securities Guarantee and the Affiliate Debenture Guarantee
Agreement, (ii) pari passu with the most senior preferred or preference stock
now or hereafter issued by the Guarantor and with any guarantee now or
hereafter entered into by the Guarantor in respect of any preferred security of
any Affiliate of the Guarantor, and (iii) senior to the Guarantor's common
stock.  Any similar guarantee given hereafter by the Company with respect to
Trust Preferred Securities that is silent as to seniority will rank pari passu
with this Trust Preferred Securities Agreement.

SECTION 7.1      Termination

         This Trust Preferred Securities Guarantee shall terminate upon (i)
full payment of the Redemption Price of all Trust Preferred Securities, (ii)
upon the distribution of the Partnership Preferred Securities to the Holders of
all of the Trust Preferred Securities or (iii) upon full payment of the amounts
payable in accordance with the Declaration upon liquidation of the Issuer.
Notwithstanding the foregoing, this Trust Preferred Securities Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any Holder of Trust Preferred Securities must restore payment of any sums
paid under the Trust Preferred Securities or under this Trust Preferred
Securities Guarantee.

                 Covered Person for any loss, damage or claim incurred by
                 reason of any act or omission performed or omitted by such
                 Indemnified Person in good faith in accordance with this Trust
                 Preferred Securities Guarantee and in a manner that such
                 Indemnified Person reasonably believed to be within the scope
                 of the authority conferred on such Indemnified Person by this
                 Trust Preferred Securities Guarantee or by law, except that an
                 Indemnified Person shall be liable for any such loss, damage
                 or claim incurred by reason of such Indemnified Person's gross
                 negligence or willful misconduct with respect to such acts or
                 omissions.

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

SECTION 8.2      Indemnification

         The Guarantor agrees to indemnify each Indemnified Person for, and to
hold each Indemnified Person harmless against, any and all loss, liability,
damage, claim or expense incurred without gross negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration of
the trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.  The obligation to
indemnify as set forth in this Section 8.2 shall survive the termination of
this Trust Preferred Securities Guarantee or the earlier resignation or removal
of the Trust Preferred Guarantee Trustee.

                                 MISCELLANEOUS

SECTION 9.1      Successors and Assigns

         All guarantees and agreements contained in this Trust Preferred
Securities Guarantee shall bind the successors, assigns, receivers, trustees
and representatives of the Guarantor and shall inure to the benefit of the
Holders of the Trust Preferred Securities then outstanding.

SECTION 9.2      Amendments

         Except with respect to any changes that do not adversely affect the
rights of Holders (in which case no consent of Holders will be required), this
Trust Preferred Securities Guarantee may only be amended with the prior
approval of the Holders of at least a Majority in liquidation amount (including
the stated amount that would be paid on redemption, liquidation or otherwise,
plus accrued and unpaid Distributions to the date upon which the voting
percentages are determined) of all the outstanding Trust Preferred Securities.
The provisions of Section 13.2 of the Declaration with respect to meetings of
Holders of the Securities apply to the giving of such approval.

SECTION 9.3      Merger of the Guarantor

         The Guarantor covenants that it will not merge or consolidate with any

its assets to any person (other than such a sale or conveyance to a Subsidiary
or any successor thereto (such a sale or conveyance being called an "Asset
Drop-Down")), unless (i) either the Guarantor shall be the continuing
corporation or the successor corporation or other entity or the person which
acquires by sale or conveyance substantially all the assets of the Guarantor

the Holders the Guarantee Payments, as and when due (without duplication of
amounts theretofore paid by the Issuer), regardless of any defense, right of
setoff or counterclaim which the Issuer may have or assert.  The Guarantor's

to pay such amounts to the Holders.

                 (c)   any failure, omission, delay or lack of diligence on the
         part of the Holders to enforce, assert or exercise any right,
         privilege, power or remedy conferred on the Holders pursuant to the
         terms of the Partnership Preferred Securities, or any action on the
         part of the Issuer granting indulgence or extension of any kind;

                 (d)  the voluntary or involuntary liquidation, dissolution,
         sale of any collateral, receivership, insolvency, bankruptcy,
         assignment for the benefit of creditors, reorganization, arrangement,
         composition or readjustment of debt of, or other similar proceedings
         affecting, the Issuer or any of the assets of the Issuer;

                 (e)  any invalidity of, or defect or deficiency in, the
         Partnership Preferred Securities;

                 (f)  the settlement or compromise of any obligation guaranteed
         hereby or hereby incurred; or

                 (g)  any other circumstance whatsoever that might otherwise
         constitute a legal or equitable discharge or defense of a guarantor,
         it being the intent of this Section 2.3 that the obligations of the
         Guarantor hereunder shall be absolute and unconditional under any and
         all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain
consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 2.4  Rights of Holders

         The Guarantor expressly acknowledges that (i) this Partnership
Guarantee Agreement will be deposited with the General Partner to be held for
the benefit of the Holders; (ii) in the event of the appointment of a Special
Representative to, among other things, enforce this Partnership Guarantee

been appointed, the General Partner has the right to enforce this Partnership
Guarantee Agreement on behalf of the Holders; (iv) the Holders of not less than
a majority in aggregate liquidation preference of the Partnership Preferred
Securities have the right to direct the time, method and place of conducting
any proceeding for any remedy available in respect of this Partnership

Partner or Special Representative fails to enforce this Partnership Guarantee
Agreement as above provided, any Holder may institute a legal proceeding
directly against the Guarantor to enforce its rights under this Partnership
Guarantee Agreement, without first instituting a legal proceeding against the
Issuer or any other person or entity.  Notwithstanding the foregoing, if the
Guarantor has failed to make a guarantee payment, a Holder may directly
institute a proceeding against the Guarantor to enforce such payment under this
Partnership Guarantee Agreement.

SECTION 2.5  Guarantee of Payment

         This Partnership Guarantee Agreement will constitute a guarantee of
payment and not of collection.

SECTION 2.6  Subrogation

         The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Partnership Guarantee Agreement provided, however, that
the Guarantor shall not (except to the extent required by mandatory provisions
of law) be entitled to enforce or exercise any rights which it may acquire by
way of subrogation or any indemnity, reimbursement or other agreement, in all
cases as a result of payment under this Partnership Guarantee Agreement, if, at
the time of any such payment, any amounts are due and unpaid under this
Partnership Guarantee Agreement.  If any amount shall be





                                       3

paid to the Guarantor in violation of the preceding sentence, the Guarantor
agrees to hold such amount in trust for the Holders and to pay over such amount
to the Holders.

SECTION 2.7  Independent Obligations

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Partnership
Preferred Securities and that the Guarantor shall be liable as principal and as
debtor hereunder to make Guarantee Payments pursuant to the terms of this
Partnership Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 2.3 hereof.

Affiliate in respect of any Affiliate Investment Instrument has occurred and is
continuing or (c) the Guarantor shall be in default with respect to its payment
obligations under this Partnership Guarantee Agreement, the Trust Preferred

obligation of the Guarantor and will rank (i) subordinate and junior in right
of payment to all other liabilities of the Guarantor, (ii) pari passu with the
most senior preferred or preference stock now or hereafter issued from time to
time by the Guarantor and with any guarantee now or hereafter entered into by
the Guarantor in respect of any preferred security of any Affiliate of the
Guarantor, and (iii) senior to the Guarantor's common stock.  Any similar
guarantee given hereafter by the Company with respect to Partnership Preferred
Securities that is silent as to seniority will rank pari passu with this
Partnership Guarantee Agreement.

other corporation or other entity or sell or convey all or substantially all of

Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the





                                       8

such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof

writing or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

         (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining
the Holders entitled to give or take any request, demand, authorization,

authorized or permitted to be given or taken by Holders.  If not set by the
Company prior to the first solicitation of a Holder made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be.  With regard to any record date, only the Holders on such date (or
their duly designated proxies) shall be entitled to give or take, or vote on,
the relevant action.

         (d) The ownership of Securities shall be proved by the Security
Register.

         (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made
upon such Security.

         (1) the Trustee by any Holder or by the Company shall be sufficient
for every purpose hereunder if made, given, furnished or filed in writing to or
with the Trustee at its Corporate Trust Office, Attention: Global Trust
Services, or

         (2) the Company by the Trustee or by any Holder shall be sufficient
for every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage

<PAGE>   16

SECTION 106.  Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in a
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed
with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

SECTION 107.  Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall
be deemed to apply to this Indenture as so modified or to be excluded, as the
case may be.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

principal of the Securities shall be made on the next succeeding day which 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 of interest or principal of the Securities, as the case may
be, shall be made on the immediately preceding Business Day (and without any
reduction in interest or principal in respect of such early payment).

                         7.75% Subordinated Debenture,

No. _____________                                                      $________

         Enron Corp., a corporation duly organized and existing under the laws
of the State of Delaware (herein called the "Company," which term includes any
successor corporation under the Indenture hereinafter referred to), for value
received, hereby promises to pay to ________________, or registered assigns,
the principal sum of ________ DOLLARS ($________) on September 30, 2016 and to
pay interest on said principal sum from November 21, 1996 or from the most
recent interest payment date (each such date, an "Interest Payment Date") to
which interest has been paid or duly provided for, quarterly (subject to
deferral as set forth herein) in arrears on March 31, June 30, September 30 and
December 31 of each year, commencing December 31, 1996, at the rate of 7.75%
per annum plus Additional Interest, if any, until the principal hereof shall
have become due and payable, and on any overdue principal. The amount of
interest payable for any period will be computed on the basis of twelve 30-day
months and a 360-day year.  In the event that any date on which interest is
payable on this Security is not a Business Day, then a payment of the interest
payable on such date will be made on the next succeeding day which is a
Business Day (and without any interest or other payment in respect of any such
delay), except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date the payment was
originally payable.  A "Business Day" shall mean any day other than a day on
which banking institutions in the City of New York are authorized or required
by law to remain closed.  The interest installment so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
the Indenture, be paid to the Person in whose name this Security (or one or
more Predecessor Securities, as defined in the Indenture) is registered at the
close of business on the Regular Record Date for such interest installment,
which shall be the close of business on the Business Day next preceding such
Interest Payment Date.  Any such interest installment not so punctually paid or
duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice of which shall be given to Holders of
Securities not less than 10 days prior to such Special Record Date, or be paid
at any time in any other lawful manner not inconsistent with the requirements
of any securities exchange on which the Securities may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in said
Indenture.





                                       12

         The Company shall have the right at any time during the term of this
Security, from time to time, to extend the interest payment period of such
Security for up to six consecutive quarters (an "Extension Period"), during
which periods interest will compound quarterly and the Company shall have the
right to make partial payments of interest on any Interest Payment Date, and at
the end of which Extension Period the Company shall pay all interest then
accrued and unpaid (together with Additional Interest thereon to the extent
that payment of such interest is permitted by applicable law).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that such Extension Period together with all
such previous and further extensions thereof shall not exceed six consecutive
quarters or extend beyond the Maturity of this Security.  Upon the termination
of any such Extension Period and upon the payment of all accrued and unpaid
interest and any Additional Interest then due, the Company may select a new
Extension Period, subject to the foregoing requirements.  No interest shall be
due and payable during an Extension Period except at the end thereof.  The
Company shall give the Holder of this Security and the Trustee written notice
of its selection of an Extension Period at least one Business Day prior to the
earlier of (i) the Interest Payment Date or (ii) the date Enron Capital Trust I
is required to give notice to the New York Stock Exchange or other applicable
self-regulatory organization or to holders of the Trust Preferred Securities of
the record date or the date such distributions are payable, but in any event
not less than one Business Day prior to such record date.

         Payment of the principal of and interest on this Security will be made
at the office or agency of the Company maintained for that purpose in New York,
New York, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
made (i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Security
Register.

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinate and subject in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto.  Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes.  Each Holder hereof, by his acceptance hereof, waives all notice of
the acceptance of the subordination provisions contained herein and in the
Indenture of each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

         Reference is hereby made to the further provisions of the Indenture
summarized on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth herein.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this
Security shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

SECTION 203.  Form of Reverse of Security.

         This Security is one of a duly authorized issue of Securities of the
Company, designated as its 7.75% Subordinated Debentures Due 2016 (herein
called the "Securities"), limited in aggregate principal amount to $181,926,000
issued under an Indenture, dated as of November 21,1996 (herein called the
"Indenture"), between the Company and The Chase Manhattan Bank, as Trustee
(herein called the "Trustee," which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Trustee, the Company and the
Holders of the Securities, and of the terms upon which the Securities are, and
are to be, authenticated and delivered.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

         At any time on or after December 31, 2001, the Company shall have the
right, subject to the terms and conditions of Article Twelve of the Indenture,
to redeem this Security at the option of the Company, without premium or
penalty, in whole or in part, at a Redemption Price equal to 100% of the
principal amount to be redeemed plus accrued but unpaid interest, including any
Additional Interest, if any, to the Redemption Date.  If a Partnership Special
Event shall occur and be continuing, the Company shall have the right, subject
to the terms and conditions of Article Twelve of the Indenture, to redeem this
Security, without premium or penalty, in whole but not in part, at a Redemption
Price equal to 100% of the principal amount thereof plus accrued but unpaid
interest, including any Additional Interest, if any, to the Redemption Date.
Any redemption pursuant to this paragraph will be made upon not less than 30
nor more than 60 days' notice, at the Redemption Price.  If the Securities are
only partially redeemed by the Company, the Securities will be redeemed pro
rata, by lot or in such other manner as the Trustee shall deem appropriate and
fair in its discretion and that may provide for the selection of a portion or
portions (equal to twenty-five U.S. dollars ($25) or any integral multiple
thereof) of the principal amount of any Security.

         In the event of redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.





                                       14
<PAGE>   21
         If an Event of Default with respect to the Securities shall occur and
be continuing, the principal of the Securities may be declared due and payable
in the manner, with the effect and subject to the conditions provided in the
Indenture.

         The Indenture contains provisions for satisfaction and discharge at
any time of the entire indebtedness of this Security upon compliance by the
Company with certain conditions set forth in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of Holders of not less than a majority in principal
amount of the Outstanding Securities, to modify the Indenture in a manner
affecting the rights of the Holders of the Securities; provided that no such
modification may, without the consent of the Holder of each Outstanding
Security, (i) extend the fixed maturity of the Securities, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any premium payable upon the redemption thereof, or
(ii) reduce the percentage of principal amount of the Securities, the Holders
of which are required to consent to any such modification of the Indenture.
The Indenture also contains provisions permitting Holders of specified
percentages in principal amount of the Securities at the time Outstanding, on
behalf of the Holders of all Securities, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in New York, New York, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities,
of authorized denominations and for the same aggregate principal amount, will
be issued to the designated transferee or transferees.  No service charge shall
be made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.

         Prior to due presentment of this security for registration of
transfer, the Company, the Trustee and any of their respective agents may treat
the Person in whose name this Security is registered as the owner hereof for
all purposes, whether or not this Security shall be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the
contrary.





                                       15
<PAGE>   22
         The Securities are issuable only in registered form without coupons in
denominations of $25 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

         THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
CONFLICTS OF LAWS PRINCIPLES THEREOF.

SECTION 204.  Form of Trustee's Certificate of Authentication.

         This is one of the Securities referred to in the within-mentioned
Indenture.

                                                    Authorized Signatory

                                 ARTICLE THREE

                                 The Securities

SECTION 301.  Title and Terms.

         The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $181,926,000,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other securities pursuant to Section
303, 304, 305, 306 or 1208.

         The Securities shall be known and designated as the "7.75%
Subordinated Debentures Due 2016" of the Company.  Their Stated Maturity shall
be September 30, 2016, and they shall bear interest at the rate of 7.75% per
annum, from November 21, 1996 or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, as the case may be, payable
quarterly (subject to deferral as set forth herein), in arrears, on March 31,
June 30, September 30 and December 31 of each year, commencing December 31,
1996 until the principal thereof is paid or made available for payment.
Interest will compound quarterly and will accrue at the rate of 7.75% per annum
on any interest installment in arrears for more than one quarter or during an
extension of an interest payment period as set forth below in this Section 301.
In the event that any date on which interest is payable on the Securities is
not a Business Day, then a payment of the interest payable on such date will be
made on the next succeeding day which is a Business Day (except that, if such
Business Day is in the next succeeding calendar year, such Interest Payment
Date shall be the immediately preceding Business Day) (and without any interest
or other payment in respect of any such delay).





                                       16
<PAGE>   23
         The Company shall have the right, at any time during the term of the
Securities, from time to time to extend the interest payment period for up to
six consecutive quarters (the "Extension Period") during which period interest
will compound quarterly and the Company shall have the right to make partial
payments of interest on any Interest Payment Date, and at the end of which
Extension Period the Company shall pay all interest then accrued and unpaid
thereon (together with Additional Interest at the rate specified for the
Securities to the extent permitted by applicable law).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that such Extension Period together with all
such previous and further extensions thereof shall not exceed six consecutive
quarters or extend beyond the Maturity of the Securities.  Upon the termination
of any Extension Period and upon the payment of all accrued and unpaid interest
and any Additional Interest then due, the Company may select a new Extension
Period, subject to the foregoing requirements.  No interest shall be due and
payable during an Extension Period, except at the end thereof.  The Company
shall give the Trust, the Partnership and the Trustee notice of its selection
of such Extension Period subject to the above requirements at least one
Business Day prior to the earlier of (i) the Interest Payment Date or (ii) the
date the Trust is required to give notice to the New York Stock Exchange or
other applicable self-regulatory organization or to holders of the Trust
Preferred Securities of the record date or the date such distributions are
payable, but in any event not less than one Business Day prior to such record
date.

         The principal of and interest on the Securities shall be payable at
the office or agency of the Company in the United States maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made (i)
by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or (ii) by wire transfer in immediately
available funds at such place and to such account as may be designated by the
Person entitled thereto as specified in the Security Register.

         The Securities shall be subordinated in right of payment to Senior
Indebtedness as provided in Article Eleven.

         The Securities shall be redeemable as provided in Article Twelve.

SECTION 302.  Denominations.

         The Securities shall be issuable only in registered form, without
coupons, and only in denominations of $25 and any integral multiple thereof.

SECTION 303.  Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of the Company by its
Chairman, one of its Vice Chairman, its President or one of its Vice
Presidents.  The signature of any of these officers on the securities may be
manual or facsimile.





                                       17
<PAGE>   24
         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

SECTION 304.  Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

         If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities
of authorized denominations.  Until so exchanged the temporary Securities shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

SECTION 305.  Registration, Registration of Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant Section 1002 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.





                                       18
<PAGE>   25
         Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 1002 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate
principal amount.

         At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at such office or
agency.  Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

         All Securities issued upon any registration of transfer or excess of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304 or 1208 not involving any transfer.

         If the Securities are to be redeemed in part, the Company will not be
required to issue, register the transfer of or exchange any Securities during a
period beginning at the opening of business 15 days before the day of mailing
of a notice of redemption of any such Securities that may be selected for
redemption and ending at the close of business on the day of such mailing,
except the unredeemed portion of any such Securities being redeemed in part.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
security and (ii) such security or indemnity as may be required by them to save
each of them and any of the officers, directors, employees or agents of either
of them harmless, then, in the absence of notice to the Company or the Trustee
that such Security has been acquired by a bona fide purchaser, the Company
shall execute and the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Security, a new Security of like tenor and
principal amount and bearing a number not contemporaneously outstanding.





                                       19
<PAGE>   26
         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

         Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

         (1) the Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest, which shall be fixed in the
following manner.  The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security and the date
of the proposed payment, and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this Clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment.  The Trustee
shall promptly notify the Company of





                                       20

such Special Record Date and, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the
Special Record Date therefor to be mailed, first-class postage prepaid, to each
Holder at his address as it appears in the Security Register, not less than 10
days prior to such Special Record Date.  Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed,
such Defaulted Interest shall be paid to the Persons in whose names the
Securities (or their respective Predecessor Securities) are registered at the
close of business on such Special Record Date and shall no longer be payable
pursuant to the following clause (2).

         (2) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and, if so listed, upon such
notice as may be required by such exchange, if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue (including in each such case Additional Interest),
which were carried by such other Security.

SECTION 308.  Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of any of them shall treat the Person in
whose name such Security is registered as the owner of such Security for the
purpose of receiving payment of principal of and (subject to Section 307)
interest (including Additional Interest) on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of them shall be affected by notice to the
contrary.

SECTION 309.  Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly cancelled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly cancelled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture.  All
cancelled Securities held by the Trustee shall be disposed of as directed by a
Company Order.

SECTION 310.  Computation of Interest.

         Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

surviving rights of registration of transfer or exchange of Securities herein
expressly provided for and any amounts owed to the Trustee hereunder), and the
Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when

         (1)  either

                 (A) all Securities theretofore authenticated and delivered
         (other than (i) Securities which have been destroyed, lost or stolen
         and which have been replaced or paid as provided in Section 306 and
         (ii) Securities for whose payment money has theretofore been deposited
         in trust or segregated and held in trust by the Company and thereafter

                 (B)  all such Securities not theretofore delivered to the
         Trustee for cancellation

                          (i) have become due and payable,

                 expense, of the Company

         and the Company, in the case of (i), (ii) or (iii) above, has
         deposited or caused to be deposited with the Trustee as trust funds in
         trust for the purpose and amount sufficient to pay and discharge the
         entire indebtedness on such Securities not theretofore delivered to
         the Trustee for cancellation, for principal and interest (including
         Additional Interest) to the date of such deposit (in the case of
         Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

         (2)  the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

         (3) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.  Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Company to the Trustee under Section 607 and,
if money shall have been deposited with the Trustee pursuant to subclause (B)
of Clause (1) of this Section,

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and interest for
whose payment such money has been deposited with the Trustee.  The Trustee
shall not invest money deposited with it pending distribution of such amounts.

                                    Remedies

SECTION 501.  Events of Default.

         "Event of Default," wherever used herein, means any one of the
following events that has occurred and is continuing (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or
governmental body):

         (1) failure for 90 days to pay any interest on the Securities,
including any Additional Interest in respect thereof, when due (subject to the
deferral of any due date in the case of an Extension Period); or

         (2) failure to pay any principal on the Securities when due whether at
Stated Maturity, upon redemption or otherwise; or

         (3) failure to observe or perform in any material respect any other
covenant herein for 90 days after written notice of such failure (specified as
a "Notice of Default"), requiring the Company to remedy the same shall have
been given to the Company by the Trustee or the holders of at least 25% in
principal amount of the Outstanding Securities; or


         (4) a court or governmental agency having jurisdiction shall enter a
decree or order for relief in respect of the Company in an involuntary case
under any applicable federal or state bankruptcy, insolvency or other similar
law now or hereafter in effect, or appointing a receiver, liquidator, assignee,
custodian, trustee, sequestrator (or similar official) of the Company or for
all or substantially all of its property or ordering the winding up or
liquidation of its affairs, and such decree or order shall remain unstayed and
in effect for a period of 90 consecutive days; or

         (5) the Company shall commence a voluntary case under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, or
consent to the entry of an order for relief in an involuntary case under any
such law, or consent to the appointment or taking possession





                                       23
<PAGE>   30
by a receiver, liquidator, assignee, custodian, trustee, sequestrator (or
similar official) of the Company or for all or substantially all of its
property or make any general assignment for the benefit of creditors; or the
Company shall admit in writing its inability to pay its debts generally as they
become due.

SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Outstanding Securities shall have the right to declare
the principal of and the interest on all the Securities (including any
Additional Interest) and any other amounts payable hereunder to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders) and to enforce any and all other rights of Holders of
Securities as creditors with respect to the Securities.  Upon any such
declaration such principal and all accrued interest shall become immediately
due and payable.

         At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter provided in this Article, the Holders of a majority
in principal amount of the Outstanding Securities, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:

         (1) the Company has paid or deposited with the Trustee a sum
sufficient to pay,

                 (A) all overdue interest (including any Additional Interest)
         on all Securities,

                 (B) the principal of any Securities which have became due
         otherwise than by such declaration of acceleration and interest
         thereon at the rate borne by the Securities, and

                 (C) all sums paid or advanced by the Trustee hereunder and the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel;  and

         (2) all Events of Default, other than the non-payment of the principal
of Securities which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

         The Company covenants that if

         (1) default is made in the payment of any interest (including any
Additional Interest) on any Security when such interest becomes due and payable
and such default continues for a period of 90 days (subject to the deferral of
any due and payable interest in the case of an Extension Period), or





                                       24
<PAGE>   31
         (2) default is made in the payment of the principal of any Security at
the Maturity thereof, the Company will, upon demand of the Trustee, pay to it,
for the benefit of the Holders of such Securities, the whole amount then due
and payable on such Securities for principal and interest (including any
Additional Interest), at the rate borne by the Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504.  Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Company, its
property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding.  In particular, the Trustee
shall be authorized to collect and receive any moneys or other property payable
or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 607.

         No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding.

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.  Application of Money Collected.

         Subject to Article Eleven, any money collected by the Trustee pursuant
to this Article shall be applied in the following order, at the date or dates
fixed by the Trustee and, in case of the distribution of such money on account
of principal or interest (including any Additional Interest), upon presentation
of the Securities and the notation thereon of the payment if only partially
paid and upon surrender thereof if fully paid:

         FIRST: To the payment of all amounts due the Trustee under Section
607;

         SECOND: To the payment of the amounts then due and unpaid for
principal of and interest (including any Additional Interest) on the Securities
in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts
due and payable on such Securities for principal and interest (including any
Additional Interest), respectively; and

         THIRD: The balance, if any, to the Company.

SECTION 507.  Limitation on Suits.

         No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

         (1) such Holder has previously given written notice to the Trustee of
a continuing Event of Default;

         (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

         (3) such Holder or Holders have offered to the Trustee such indemnity
as is satisfactory to it against the costs, expenses and liabilities to be
incurred in compliance with such request;

         (4) the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such proceeding; and

         (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities; it being understood and
intended that no one or more Holders shall have any right in any manner
whatever by virtue of, or by availing of, any provision of this Indenture to
affect, disturb or prejudice the rights of any other Holders, or to obtain or
to seek to obtain priority or preference over any other Holders or to enforce
any right under this Indenture, except in the manner herein provided and for
the equal and ratable benefit of all the Holders.

<PAGE>   33
SECTION 508.  Unconditional Right of Holders to Receive Principal and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and (subject to Section 307) interest
(including any Additional Interest) on such Security on the respective Stated
Maturities (subject to the deferral of any due date in the case of an Extension
Period) expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

SECTION 509.  Restoration of Rights and Remedies.

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

SECTION 510.  Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.

SECTION 511.  Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 512.  Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee, provided that

         (1) such direction shall not be in conflict with any rule of law or
with this Indenture; and





                                       27
<PAGE>   34
         (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.

SECTION 513.  Waiver of Past Defaults.

         Subject to Section 902, the Holders of not less than a majority in
principal amount of the Outstanding Securities may on behalf of the Holders of
all the Securities waive any past default hereunder and its consequences,
except a default

         (1) in the payment of the principal of or interest (including any
Additional Interest) on any Security (unless such default has been cured and a
sum sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration have been deposited with the Trustee); or

         (2) in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such court
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in
the Trust Indenture Act; provided, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or the Trustee or in any suit for the enforcement of the right to receive the
principal of and interest (including any Additional Interest) on any Security.

SECTION 515.  Acknowledgment.

         The Company acknowledges that so long as the Partnership is a Holder,
a holder of record of Preferred Securities may to the fullest extent permitted
by law on behalf of the Partnership, when and as provided in the Limited
Partnership Agreement, directly institute a legal proceeding against the
Company under this Indenture, without first instituting any legal proceeding
against the Property Trustee  (as such term is defined in the Limited
Partnership Agreement) or any other party.

         The duties and responsibilities of the Trustee shall be as provided by

Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any 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 grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection
to the Trustee shall be subject to the provisions of this Section.

default of the character specified in Section 501(3), no such notice to Holders

be herein specifically prescribed) may, in the absence of bad faith on its
part, conclusively rely upon an Officers' Certificate;

         (d) the Trustee may, at the Company's expense, consult with counsel of
its choice, and the advice of such counsel or any Opinion of Counsel shall be
full and complete authorization and





                                       29
<PAGE>   36
protection in respect of any action taken, suffered or omitted by it hereunder

         (e) the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of

costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction;

Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the

this Indenture;

         (i)  no provision of this Indenture shall require the 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 grounds to believe that
repayments of such funds or indemnity satisfactory to it against any loss,
liability or expense is not reasonably assured to it;

         (j)  the Trustee shall have no duty to monitor the performance of the
Company or its compliance with the covenants contained herein, nor shall it
have any liability in connection with the malfeasance or nonfeasance by the

         (c) The Trustee may be removed at any time by Act of the Holders of a

<PAGE>   39
then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the

If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders and accepted appointment in the manner hereinafter provided, any Holder
who has been a bona fide Holder of a Security for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee.

         (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee to all Holders in
the manner provided in Section 106.  Each notice shall include the name of the

omissions of any successor Trustee.

SECTION 611.  Acceptance of Appointment by Successor.

         Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers,
trusts and duties of the retiring Trustee; provided that, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its fees, charges and expenses, execute and deliver an instrument transferring
to such successor Trustee all the rights, powers and trusts of the retiring
Trustee and shall duly assign, transfer and deliver to such successor Trustee
all property and money held by such retiring Trustee hereunder.  Upon request
of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts.

         No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.

<PAGE>   40
the Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Trustee, shall be the
successor of the Trustee 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.  In case any Securities shall have been authenticated, but not
delivered, by the Trustee then in office, any successor by merger, conversion
or consolidation to such authenticating Trustee may adopt such authentication
and deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

SECTION 613.  Preferential Collection of Claims Against Company.

         If and when the Trustee shall be or become a creditor of the Company,
the Trustee shall be subject to the provisions of the Trust Indenture Act

obligor).

SECTION 614.  Character of Expenses.

         When the Trustee incurs expenses or renders services in connection
with an Event of Default, or any bankruptcy or insolvency in respect of the
Company, such expenses (including the fees and expenses of its counsel) and the

administration under any bankruptcy law or law relating to creditors' rights
generally.

30 days after the receipt by the Company of any such request, a list of similar
form and content as of a date not more than 15 days prior to the time such list
is furnished, excluding from any such list names and addresses received by the
Trustee in its capacity as Security Registrar.

SECTION 702.  Preservation of Information; Communications to Holders.

practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in

the Trust Indenture Act.

SECTION 703.  Reports by Trustee.

         (a) The Trustee shall transmit to Holders such reports concerning the

              Consolidation, Merger, Conveyance, Transfer or Lease

SECTION 801.  Company May Consolidate, Etc., Only on Certain Terms.

         The Company covenants that it will not merge or consolidate with any
other corporation or other entity or sell or convey all or substantially all of
its assets to any person (other than such a sale or conveyance to a Subsidiary
or any successor thereto (such a sale or conveyance being called an "Asset
Drop-Down")), unless (i) either the Company shall be the continuing corporation
or the successor corporation or other entity or the person which acquires by
sale or conveyance substantially all the assets of the Company shall expressly
assume the due and punctual payment of the principal of, premium, if any, and
interest, if any, on all the Securities, according to their tenor, and the due
and punctual performance and observance of all of the covenants and conditions
of this Indenture to be performed or observed by the Company, by supplemental
indenture in form satisfactory to the Trustee, executed and delivered to the
Trustee by such corporation or other entity, and (ii) the Company or such
successor corporation or other entity, as the case may be, shall not,
immediately after such merger or consolidation, or such sale or conveyance, be
in default in the performance of any such covenant or condition.  In the event
of any Asset Drop-Down after the date of this Indenture, any subsequent sale or
conveyance of assets by a Subsidiary to which assets were transferred in such
Asset Drop-Down (a "Drop-Down Subsidiary") will be deemed to be a sale or
conveyance of assets by the Company for purposes of this Section 801.

<PAGE>   42
SECTION 802.  Successor Substituted.

         In case of any such consolidation, merger, sale or conveyance, and
following such an assumption by the successor corporation, such successor
corporation shall succeed to and be substituted for the Company, with the same
effect as if it had been named herein.  Such successor corporation may cause to
be signed, and may issue either in its own name or in the name of the Company
prior to such succession any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation instead of the
Company and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the
officers of the Company to the Trustee for authentication, and any Securities
which such successor corporation thereafter shall cause to be signed and
delivered to the Trustee for that purpose.  All of the Securities so issued
shall in all respects have the same legal rank and benefit under this Indenture
as the Securities theretofore or thereafter issued in accordance with the terms
of this Indenture as though all of such Securities had been issued at the date
of the execution hereof.

         In case of any such consolidation, merger, sale, lease or conveyance
such changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

         In the event of any such sale or conveyance (other than a conveyance
by way of lease) the Company or any successor corporation which shall
theretofore have become such in the manner described in this Article shall be
released and discharged from all obligations and covenants under this
Indenture.

                                  ARTICLE NINE

                            Supplemental Indentures

Board Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of

of interest (including any Additional Interest) on, any Security, or reduce the
principal amount thereof or the rate of interest thereon, or change the place
of payment where, or the coin or currency in which, any Security or interest
thereon is payable, or impair the right to institute suit for the enforcement
of any such payment on or after the Stated Maturity thereof (or, in the case of
redemption, on or after the Redemption Date), or modify the provisions of this
Indenture with respect to the subordination of the Securities in a manner
adverse to the Holders,

         (2) reduce the percentage in principal amount of the Outstanding
Securities, the consent of whose Holders is required for any such supplemental
indenture, or the consent of whose Holders in required for any waiver (of

         (3) modify any of the provisions of this Section or Section 513,
except to increase any such percentage or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent
of the Holder of each Outstanding Security affected thereby.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it

SECTION 903.  Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby

                                       37
<PAGE>   44
upon an Officer's Certificate stating that all conditions precedent to the
execution of such supplemental indenture have been fulfilled and an Opinion of
Counsel stating that the execution of such supplemental indenture is authorized
or permitted by this Indenture.  The Trustee may, but shall not be obligated
to, enter into any such supplemental indenture which affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

SECTION 904.  Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental

Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

SECTION 905.  Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

         The Company will maintain in New York, New York, an office or agency
where Securities may be presented or surrendered for payment, where Securities

and demands to or upon the Company in respect of the Securities and this
Indenture may be served.  The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency.  If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

         The Company may also from time to time designate one or more other
offices or agencies in the United States where the Securities may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in New York, New York for such purposes.  The Company will give
prompt written





                                       38
<PAGE>   45
notice to the Trustee of any such designation or rescission and of any change
in the location of any such other office or agency.

SECTION 1003.  Money for Security Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent, it will,
on or at the option of the Company before each due date of the principal of or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Persons entitled thereto a sum sufficient to pay the principal or
interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents, it will, on
or prior to each due date of the principal of or interest on any Securities,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or interest on any
Security and remaining unclaimed for two years after such principal or interest
has become due and payable shall be paid to the Company on a Company Request,
or (if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease.

the times and in the manner provided pursuant to such Act; provided that any
such information, documents or reports required to be filed with the Commission
pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 shall be
filed with the Trustee within 15 days after the same is so required to be filed
with the Commission.  Delivery of such reports, information and documents to
the Trustee is for informational purposes only and the Trustee's receipt of
such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the
Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

SECTION 1005.  Negative Pledge and Exceptions Thereto.

         So long as any of the Securities are outstanding, the Company will not

shall be equally and ratably secured with any and all such indebtedness and
with any other indebtedness similarly entitled to be equally and ratably

         delinquent but the validity of which is being contested at the time by
         the Company or such Subsidiary in good faith;

                 (e)      the lien reserved in leases for rent and for
         compliance with the terms of the lease in the case of leasehold
         estates;

                 (f)      any obligations or duties, affecting the property of

         similar arrangement;

                 (g)      the liens of any judgments or attachments in an
         aggregate amount not in excess of $10,000,000, or the lien of any
         judgment or attachment the execution or enforcement of which has been
         stayed or which has been appealed and secured, if necessary, by the
         filing of an appeal bond;

         income of the holder of such security pursuant to the Internal Revenue
         Code of 1954, as amended, for the purpose of financing, in whole or in
         part, the acquisition or construction of property to be used by the
         Company or a Subsidiary; or

                 (s)      the pledge or assignment of accounts receivable, or

         of goods or merchandise to customers of the Company or such
         Subsidiary.

         In case the Company or any Subsidiary shall propose to pledge,
mortgage or hypothecate any Principal Property at any time owned by it to
secure any indebtedness, other than as permitted by subdivisions (a) to (s),
inclusive, of this Section 1005, the Company will prior thereto give written
notice thereof to the Trustee, and the Company will, or will cause such
Subsidiary to, prior to or simultaneously with such pledge, mortgage or
hypothecation, enter into a supplemental with the Trustee (or to the extent
legally necessary to another trustee or additional or separate trustee) that
secures all the Securities equally and ratably with such indebtedness.

         Notwithstanding the foregoing provisions of this Section 1005, the
Company or a Subsidiary may issue, assume or guarantee indebtedness secured by
mortgage which would otherwise be subject to the foregoing restrictions in an
aggregate amount which, together with all other indebtedness of the Company or
a Subsidiary secured by a mortgage which (if originally issued, assumed or
guaranteed at such time) would otherwise be subject to the foregoing
restrictions (not including indebtedness permitted to be secured under clauses
(a) through (s) above), does not at the time exceed 10% of the Consolidated Net
Tangible Assets of the Company, as shown on the audited consolidated financial
statements of the Company as of the end of the fiscal year preceding the date
of determination.

SECTION 1006.  Statement as to Compliance; Notice of Certain Events of Default.

commencing with the first fiscal year following the issuance of Securities
under this Indenture, file with the Trustee a certificate of the principal
executive officer, the principal financial officer or the principal accounting
officer of the Company covering the period from the date of issuance of such
Securities to the end of the fiscal year in which such Securities were issued,
in the case of the first such certificate, andcovering the preceding fiscal
year in the case of each subsequent certificate, and stating whether or

not, to the knowledge of the signer, the Company has complied with all
conditions and covenants on its part contained in this Indenture, and, if the
signer has obtained knowledge of any default by the Company in the performance,
observance or fulfillment of any such condition or covenant, specifying each
such default and the nature thereof.  For the purpose of this Section 1007,
compliance shall be determined without regard to any grace period or
requirement of notice provided pursuant to the terms of this Indenture.

                                 ARTICLE ELEVEN

                          Subordination of Securities

SECTION 1101.  Securities Subordinate to Senior Indebtedness.

         The Company covenants and agrees, and each Holder of a Security, by
his acceptance thereof, likewise covenants and agrees, that, notwithstanding
anything to the contrary contained herein, to the extent and in the manner
hereinafter set forth in this Article, the indebtedness represented by the
Securities and the payment of the principal of and premium, if any, and
interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full in
cash or cash equivalents of all Senior Indebtedness (including any interest
accruing after the occurrence of an Event of Default under Section 501(4) or
(5)).

SECTION 1102.  Payment Over of Proceeds upon Dissolution, etc.

         In the event of (a) any insolvency or bankruptcy case or proceeding,
or any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its
creditors, as such, or to its assets, or (b) any liquidation, dissolution or
other winding up of the Company, whether voluntary or involuntary and whether
or not involving insolvency or bankruptcy, or (c) any assignment for the
benefit of creditors or any other marshalling of assets and liabilities of the
Company, then and in any such event:

         (1) the holders of Senior Indebtedness shall be entitled to receive
payment in full in cash or cash equivalents of all amounts due or to become due
on or in respect of all Senior Indebtedness, or provision shall be made for
such payment in cash or cash equivalents, before the Holders of the Securities
are entitled to receive any payment on account of principal of (or premium, if
any) or interest on the Securities; and

         (2) any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, by set-off or otherwise,
to which the Holders or the Trustee would be entitled but for the provisions of
this Article Eleven, including any such payment or distribution which may be
payable or deliverable by reason of the payment of any other indebtedness of
the Company being subordinated to the payment of the Securities (except for any
such payment or distribution of securities which (i) are unsecured, (ii) have
an average life and final maturity no shorter than the average life and final
maturity of the Securities and (iii) are subordinated, to at least the same
extent as the Securities, to the payment of all Senior Indebtedness then
outstanding), shall be paid by the liquidating trustee or agent or other person
making such payment or distribution,





                                       43
<PAGE>   50
whether a trustee in bankruptcy, a receiver or liquidating trustee or
otherwise, directly to the holders of Senior Indebtedness or their
Representative or Representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior
Indebtedness may have been issued, ratably according to the aggregate amounts
remaining unpaid on account of the principal of, and premium, if any, and
interest on, and other amounts due on or in connection with, the Senior
Indebtedness to the extent necessary to make payment in full in cash or cash
equivalents of all Senior Indebtedness remaining unpaid, after giving effect to
any concurrent payment or distribution to the holders of such Senior
Indebtedness; and

         (3) in the event that, notwithstanding the foregoing provisions of
this Section, the Trustee or the Holder of any Security shall have received any
such payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, including any such payment or
distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of the
Securities, before all Senior Indebtedness is paid in full or payment thereof
provided for, then and in such event such payment or distribution shall be paid
over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payment or
distribution of assets of the Company for application to the payment of all
Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior
Indebtedness in full in cash or cash equivalents, after giving effect to any
concurrent payment or distribution to or for the holders of Senior
Indebtedness.

         The consolidation of the Company with, or the merger of the Company
into, another corporation or the liquidation or dissolution of the Company
following the conveyance, transfer or lease of its properties and assets
substantially as an entirety to another corporation upon the terms and
conditions set forth in Article Eight shall not be deemed a dissolution,
winding up, liquidation, reorganization, assignment for the benefit of
creditors or marshalling of assets and liabilities of the Company for the
purposes of this Section if the corporation formed by such consolidation or
into which the Company is merged or the corporation which acquires by
conveyance, transfer or lease such properties and assets substantially as an
entirety, as the case may be, shall, as a part of such consolidation, merger,
conveyance, transfer or lease, comply with the conditions set forth in Article
Eight.

SECTION 1103.  No Payment When Senior Indebtedness in Default.

         No payment of principal (including redemption payments), premium, if
any, or interest on the Securities may be made (i) if any Senior Indebtedness
is not paid when due, (ii) if any applicable grace period with respect to such
payment default on Senior Indebtedness has ended and such default has not been
cured or waived or ceased to exist, or (iii) if the maturity of any Senior
Indebtedness of the Company has been accelerated because of a default.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, then and in such event such payment shall
be received and held in trust for the holders of Senior Indebtedness and shall
be paid over or delivered to the Representative of Senior Indebtedness then
outstanding to the extent necessary to pay in full in cash or cash equivalents
all Senior Indebtedness.





                                       44
<PAGE>   51
         The provisions of this Section shall not apply to any payment with
respect to which Section 1102 would be applicable.

SECTION 1104.  Payment Permitted If No Default.

         Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent the Company, at any time except during the
pendency of any case, proceeding, dissolution, liquidation or other winding up,
assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 1102 or under the conditions
described in Section 1103, from making payments at any time of principal of
(and premium, if any) or interest on the Securities.

SECTION 1105.  Subrogation to Rights of Holders of Senior Indebtedness.

         Subject to the payment in full of all Senior Indebtedness, the Holders
of the Securities shall be subrogated (equally and ratably with the holders of
all indebtedness of the Company which by its express terms is subordinated to
Senior Indebtedness of the Company to the same extent as the Securities are
subordinated and which is entitled to like rights of subrogation) to the rights
of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full.  For purposes of such subrogation, no
payments or distributions to the holders of Senior Indebtedness of any cash,
property or securities to which the Holders of the Securities or the Trustee
would be entitled except for the provisions of this Article, and no payments
over pursuant to the provisions of this Article to the holders of Senior
Indebtedness by Holders of the Securities or the Trustee, shall, as among the
Company, its creditors other than holders of Senior Indebtedness, and the
Holders of the Securities, be deemed to be a payment or distribution by the
Company to or on account of the Senior Indebtedness.

SECTION 1106.  Provisions Solely to Define Relative Rights.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand.  Nothing
contained in this Article or elsewhere in this Indenture or in the Securities
is intended to or shall (a) impair, as among the Company, its creditors other
than holders of Senior Indebtedness and the Holders of the Securities, the
obligation of the Company, which is absolute and unconditional, to pay to the
Holders of the Securities the principal of (and premium, if any) and interest
on the Securities as and when the same shall become due and payable in
accordance with their terms; or (b) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other
than the holders of Senior Indebtedness; or (c) prevent the Trustee or the
Holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the express
limitations set forth in Article Five and to the rights, if any, under this
Article of the holders of Senior Indebtedness (1) in any case, proceeding,
dissolution, liquidation or other winding up, assignment for the benefit of
creditors or other marshalling of assets and liabilities of the Company
referred to in Section 1102, to receive, pursuant to and in accordance with
such Section, cash, property and securities otherwise





                                       45
<PAGE>   52
payable or deliverable to the Trustee or such Holder, or (2) under the
conditions specified in Section 1103, to prevent any payment prohibited by such
Section.

SECTION 1107.  Trustee to Effectuate Subordination.

         Each Holder of a Security by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.
SECTION 1108.  No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article
or the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (a) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (b) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness; (c) release any Person liable in any manner for
the collection of Senior Indebtedness; and (d) exercise or refrain from
exercising any rights against the Company and any other Person.

SECTION 1109.  Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Securities.  Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payments to or by the Trustee in respect of the Securities,
unless and until the Trustee shall have received written notice thereof at the
Corporate Trust Office of the Trustee from the Company or a holder of Senior
Indebtedness or from any trustee, fiduciary or agent therefor; and, prior to
the receipt of any such written notice, the Trustee, subject to the provisions
of Section 603, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall not have received the
notice provided for in this Section 1109 at least three Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of (and
premium, if any) or interest on any Security), then, anything herein contained
to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for





                                       46
<PAGE>   53
which such money was received and shall not be affected by any notice to the
contrary which may be received by it within three Business Days prior to such
date.  Nothing in this Section 1109 shall limit the right of the holders of
Senior Indebtedness to recover payments as contemplated by Section 1102 and
1103.

         Subject to the provisions of Section 603, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee,
fiduciary or agent therefor) to establish that such notice has been given by a
holder of Senior Indebtedness (or a trustee, fiduciary or agent therefor).  In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

SECTION 1110.  Reliance on Judicial Order or Certificate of Liquidating Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Section 603, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.
SECTION 1111.  Rights of Trustee as a Holder of Senior Indebtedness;
Preservation of Trustee's Rights.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.





                                       47
<PAGE>   54
SECTION 1112.  Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided,
however, that (i) Section 1111 shall not apply to the Company or any Affiliate
of the Company if it or such Affiliate acts as Paying Agent and (ii) any notice
required by this Article Eleven to be given by the holders of, or a
Representative for, Senior Indebtedness need only be given to the Trustee and
not to any Paying Agent.

                                 ARTICLE TWELVE

                            Redemption of Securities

SECTION 1201.  Optional Redemption.

         (a) At any time on or after December 31, 2001, the Company shall have
the right to redeem the Securities, in whole or in part, from time to time, at
a Redemption Price equal to 100% of the principal amount of Securities to be
redeemed plus accrued but unpaid interest, including any Additional Interest,
if any, to the Redemption Date.

         (b) If, at any time, a Partnership Tax Event or a Partnership
Investment Company Event (each a "Partnership Special Event") shall occur and
be continuing, the Company may, within 90 days following the occurrence of such
Partnership Special Event, elect to redeem the Securities in whole (but not in
part), upon not less than 30 or more than 60 days' notice at the Redemption
Price, provided that, if at the time there is available to the Company or the
Partnership the opportunity to eliminate, within such 90-day period, the
Partnership Special Event by taking some ministerial action, such as filing a
form or making an election, or pursuing some other similar reasonable such
measure that in the sole judgment of the Company has or will cause no adverse
effect on the Partnership, the Trust or the Company, the Company will pursue
such measure in lieu of redemption.  SECTION 1202.  Applicability of Article.

         Redemption of Securities, at the election of the Company as permitted
by Section 1201, shall be made in accordance with such provision and this
Article.

SECTION 1203.  Authorization for Redemption; Notice to Trustee.

         The election of the Company to redeem Securities pursuant to Section
1201 shall be evidenced by a Board Resolution.  In case of any redemption, the
Company shall, at least 30 days and no more than 60 days prior to the
Redemption Date fixed by the Company, notify the Trustee of such Redemption
Date and of the principal amount of Securities to be redeemed and provide a
copy of the notice of redemption given to Holders of Securities to be redeemed
pursuant to Section 1204.

<PAGE>   55
SECTION 1204.  Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Trustee, from the Outstanding Securities not previously called for
redemption, by such method (including pro rata or by lot) as the Trustee shall
deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to $25 or any integral multiple thereof) of the
principal amount of the Securities.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to
be redeemed.

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part.  In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1205.  Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall identify the Securities to be redeemed
and shall state:

         (2) the Redemption Price,

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1206.  Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

SECTION 1207.  Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid, bear
interest from the Redemption Date at the rate borne by the Security.

SECTION 1208.  Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a place of payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.  The Company may not redeem fewer than all the
Outstanding Securities unless all accrued and unpaid interest (including
Additional Interest) has been paid on such Securities.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

SECTION 104.  Acts of Holders; Record Dates.

   (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Holders in person or by agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee and, where it is hereby expressly required, to the Company and/or the
Guarantor.  Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments.  Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for
any purpose of this Indenture and (subject to Section 601) conclusive in favor
of the Trustee and the Company and the Guarantor, if made in the manner
provided in this Section.

   (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by
a certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such
instrument or writing acknowledged to him the execution thereof.  Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

   (c) The Company may, in the circumstances permitted by the Trust Indenture
Act, fix any day as the record date for the purpose of determining the Holders
entitled to give or take any request, demand, authorization, direction, notice,
consent, waiver or other action, or to vote on any action, authorized or
permitted to be given or taken by Holders.  If not set by the Company prior to
the first solicitation of a Holder made by any Person in respect of any such
action, or, in the case of any such vote, prior to such vote, the record date
for any such action or vote shall be the 30th day (or, if later, the date of
the most recent list of Holders required to be provided pursuant to Section
701) prior to such first solicitation or vote, as the case may be.  With regard
to any record date, only the Holders on such date (or their duly designated
proxies) shall be entitled to give or take, or vote on, the relevant action.

   (d) The ownership of Securities shall be proved by the Security Register.





                                       9
<PAGE>   16
   (e) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of
the same Security and the Holder of every Security issued upon the registration
of transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

SECTION 105.  Notices, Etc., to Trustee, the Company and the Guarantor.

   Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

   (1) the Trustee by any Holder or by the Company or the Guarantor shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, Global Trust
Services, or

   (2) the Company or the Guarantor by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to the Company
or the Guarantor addressed to it at the address of its principal office
specified below or at any other address previously furnished in writing to the
Trustee by the Company or the Guarantor, as the case may be.

   If to the Company or the Guarantor to:

         1400 Smith Street
         Houston, Texas 77002
         Attention: Treasurer

SECTION 106.  Notice to Holders; Waiver.

   Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in a
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed
with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver.





                                       10
<PAGE>   17
   In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107.  Conflict with Trust Indenture Act.

   If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control.  If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 108.  Effect of Headings and Table of Contents.

   The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

SECTION 109.  Successors and Assigns.

   The Company will have the right at all times to assign any of its rights or
obligations under this Indenture to a direct or indirect wholly-owned
Subsidiary, provided that, in the event of any such assignment, the Company
will remain liable for all such obligations.  Subject to the foregoing, this
Indenture is binding upon and inures to the benefit of the parties hereto and
their respective successors and assigns. This Indenture may not otherwise be
assigned by the parties hereto.

SECTION 110.  Separability Clause.

   In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.


SECTION 111.  Benefits of Indenture.

   Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness, the holders of Preferred
Securities (to the extent provided herein) and the Holders of Securities, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 113.  Legal Holidays.

   In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of interest or
principal of the Securities shall be made on the next succeeding day which 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 of interest or principal of the Securities, as the case may
be, shall be made on the immediately preceding Business Day, in each case, with
the same force and effect as if made on the Interest Payment Date or Redemption
Date, or at the Stated Maturity and with no reduction in interest or principal
in respect of such early payment.

No. _____________                                                      $________

   Enron Pipeline Company, a corporation duly organized and existing under the
laws of the State of Delaware (herein called the "Company", which term includes
any successor corporation under the Indenture hereinafter referred to), for
value received, hereby promises to pay to ________________, or registered
assigns, the principal sum of ________ DOLLARS ($________) on September 30,
2016 and to pay interest on said principal sum from November 21, 1996 or from
the most recent interest payment date (each such date, an "Interest Payment
Date") to which interest has been paid or duly provided for, quarterly (subject
to deferral as set forth herein) in arrears on





                                       12
<PAGE>   19
March 31, June 30, September 30 and December 31 of each year, commencing
December 31, 1996, at the rate of 7.75% per annum plus Additional Interest, if
any, until the principal hereof shall have become due and payable, and on any
overdue principal. The amount of interest payable for any period will be
computed on the basis of twelve 30-day months and a 360-day year.  In the event
that any date on which interest is payable on this Security is not a Business
Day, then a payment of the interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on the date the payment was originally payable.  A "Business Day"
shall mean any day other than a day on which banking institutions in the City
of New York are authorized or required by law to remain closed.  The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the Person
in whose name this Security (or one or more Predecessor Securities, as defined
in the Indenture) is registered at the close of business on the Regular Record
Date for such interest installment, which shall be the close of business on the
Business Day next preceding such Interest Payment Date.  Any such interest
installment not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date and may either be paid
to the Person in whose name this security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in said Indenture.

   The Company shall have the right at any time during the term of this
Security, from time to time, to extend the interest payment period of such
Security for up to six consecutive quarters (an "Extension Period"), during
which periods interest will compound quarterly and the Company shall have the
right to make partial payments of interest on any Interest Payment Date, and at
the end of which Extension Period the Company shall pay all interest then
accrued and unpaid (together with Additional Interest thereon to the extent
that payment of such interest is permitted by applicable law).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that such Extension Period together with all
such previous and further extensions thereof shall not exceed six consecutive
quarters or extend beyond the Maturity of this Security.  Upon the termination
of any such Extension Period and upon the payment of all accrued and unpaid
interest and any Additional Interest then due, the Company may select a new
Extension Period, subject to the foregoing requirements.  No interest shall be
due and payable during an Extension Period except at the end thereof.  The
Company shall give the Holder of this Security and the Trustee written notice
of its selection of an Extension Period at least one Business Day prior to the
earlier of (i) the Interest Payment Date or (ii) the date Enron Capital Trust I
is required to give notice to the New York Stock Exchange or other applicable
self-regulatory organization or to holders of the Trust Preferred Securities of
the record date or the date such distributions are payable, but in any event
not less than one Business Day prior to such record date.

<PAGE>   20
   Payment of the principal of and interest on this Security will be made at
the office or agency of the Company maintained for that purpose in New York,
New York, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
made (i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Security
Register.

   Reference is hereby made to the further provisions of the Indenture
summarized on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

   Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

   IN WITNESS WHEREOF, Enron Pipeline Company has caused this instrument to be
duly executed under its corporate seal.

reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Trustee, the Company, the

   At any time on or after December 31, 2001, the Company shall have the right,
subject to the terms and conditions of Article Twelve of the Indenture, to

Additional Interest, if any, to the Redemption Date.  If a Partnership Special
Event shall occur and be continuing, the Company shall have the right, subject

Security, without premium or penalty, in whole but not in part, at a Redemption

Any redemption pursuant to this paragraph will be made upon not less than 30
nor more than 60 days' notice, at the Redemption Price.  If the Securities are
only partially redeemed by the Company, the Securities will be redeemed pro
rata, by lot or in such other manner as the Trustee shall deem appropriate and
fair in its discretion and that may provide for the selection of a portion or
portions (equal to twenty-five U.S. dollars ($25) or any integral multiple
thereof) of the principal amount of any Security.

   In the event of redemption of this Security in part only, a new Security or
Securities for the unredeemed portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

   If an Event of Default with respect to the Securities shall occur and be
continuing, the principal of the Securities may be declared due and payable in
the manner, with the effect and subject to the conditions provided in the
Indenture.

   The Indenture contains provisions for satisfaction and discharge at any time

such modification may, without the consent of the Holder of each Outstanding
Security, (i) extend the fixed maturity of the Securities, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any premium payable upon the redemption thereof, or
(ii) reduce the percentage of principal amount of the Securities, the Holders
of which are required to consent to any such modification of the Indenture.

percentages in principal amount of the Securities at the time Outstanding, on
behalf of the Holders of all Securities, to waive compliance by the Company or
the Guarantor with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences.  Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu

Security.

the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the

authorized in writing, and thereupon one or more new Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to
the designated transferee or transferees.  No service charge shall be made for
any such registration of transfer or exchange, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

   Prior to due presentment of this security for registration of transfer, the
Company, the Guarantor, the Trustee and any of their respective agents may
treat the Person in whose name this Security is registered as the owner hereof

the Company, the Guarantor, the Trustee nor any such agent shall be affected by
notice to the contrary.

denominations of $25 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS

                                 The Securities

SECTION 301.  Title and Terms.

   The aggregate principal amount of Securities which may be authenticated and
delivered under this Indenture is limited to $29,108,000, except for Securities
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, other securities pursuant to Section 303, 304, 305, 306,
906 or 1209.

   The Securities shall be known and designated as the "7.75% Debentures Due
2016" of the Company.  Their Stated Maturity shall be September 30, 2016, and
they shall bear interest at the rate of 7.75% per annum, from November 21, 1996
or from the most recent Interest Payment Date to which interest has been paid
or duly provided for, as the case may be, payable quarterly (subject to
deferral as set forth herein), in arrears, on March 31, June 30, September 30
and December 31 of each year, commencing December 31, 1996 until the principal
thereof is paid or made available for payment.  Interest will compound
quarterly and will accrue at the rate of 7.75% per annum on any interest
installment in arrears for more than one quarter or during an extension of an
interest payment period as set forth below in this Section 301.  In the event
that any date on which interest is payable on the Securities is not a Business
Day, then a payment of the interest payable on such date will be made on the
next succeeding day which is a Business Day (except that, if such Business Day
is in the next succeeding calendar year, such Interest Payment Date shall be
the immediately preceding Business Day) (and without any interest or other
payment in respect of any such delay).

   The Company shall have the right, at any time during the term of the
Securities, from time to time to extend the interest payment period for up to
six consecutive quarters (the "Extension Period") during which period interest
will compound quarterly and the Company shall have the right to make partial
payments of interest on any Interest Payment Date, and at the end of which
Extension Period the Company shall pay all interest then accrued and unpaid
thereon (together with Additional Interest at the rate specified for the
Securities to the extent permitted by applicable law).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that such Extension Period together with all
such previous and further extensions thereof shall not exceed six consecutive
quarters or extend beyond the Maturity of the Securities.  Upon the termination
of any Extension Period and upon the payment of all accrued and unpaid interest
and any Additional Interest then due, the Company may select a new Extension
Period, subject to the foregoing requirements.  No interest shall be due and
payable during an Extension Period, except at the end thereof.  The Company
shall give the Trust, the Partnership and the Trustee notice of its selection
of such Extension Period subject to the above requirements at least one
Business Day prior to the earlier of (i) the Interest Payment Date or (ii) the
date the Trust is required to give notice to the New York Stock Exchange or
other applicable self-regulatory organization or to holders of the Trust
Preferred Securities of the record date or the date such distributions are
payable, but in any event not less than one Business Day prior to such record
date.

<PAGE>   24
   The principal of and interest on the Securities shall be payable at the
office or agency of the Company in the United States maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made (i)
by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or (ii) by wire transfer in immediately
available funds at such place and to such account as may be designated by the
Person entitled thereto as specified in the Security Register.

   The Securities shall be guaranteed by the Guarantor as provided in Article
Eleven.

   The Securities shall be redeemable as provided in Article Twelve.

SECTION 302.  Denominations.

   The Securities shall be issuable only in registered form, without coupons,
and only in denominations of $25 and any integral multiple thereof.

SECTION 303.  Execution, Authentication, Delivery and Dating.

   The Securities shall be executed on behalf of the Company by its Chairman,
one of its Vice Chairman, its President, one of its Managing Directors or one
of its Vice Presidents.  The signature of any of these officers on the
securities may be manual or facsimile.

   Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.


   At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company to the
Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

   Each Security shall be dated the date of its authentication.

   No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.





                                       18

SECTION 304.  Temporary Securities.

   Pending the preparation of definitive Securities, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their
execution of such Securities.

   If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities
of authorized denominations.  Until so exchanged the temporary Securities shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

SECTION 305.  Registration, Registration of Transfer and Exchange.

   The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant Section 1002 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.


   Upon surrender for registration of transfer of any Security at an office or
agency of the Company designated pursuant to Section 1002 for such purpose, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
any authorized denominations and of a like aggregate principal amount.

   At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at such office or
agency.  Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

   All Securities issued upon any registration of transfer or excess of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

   Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written





                                       19
<PAGE>   26
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing.

   No service charge shall be made for any registration of transfer or exchange
of Securities, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Securities, other than exchanges
pursuant to Section 304, 906 or 1209 not involving any transfer.

   If the Securities are to be redeemed in part, the Company will not be
required to issue, register the transfer of or exchange any Securities during a
period beginning at the opening of business 15 days before the day of mailing
of a notice of redemption of any such Securities that may be selected for
redemption and ending at the close of business on the day of such mailing,
except the unredeemed portion of any such Securities being redeemed in part.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

   If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

   If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any security and (ii)
such security or indemnity as may be required by them to save each of them and
any of their officers, directors, employees or agents of either of them
harmless, then, in the absence of notice to the Company or the Trustee that
such Security has been acquired by a bona fide purchaser, the Company shall
execute and the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security, a new Security of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

   In case any such mutilated, destroyed, lost or stolen Security has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, pay such Security.

   Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses
(including the fees and expenses of the Trustee) connected therewith.

   Every new Security issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen
Security shall be at any time enforceable by anyone, and shall be entitled to
all the benefits of this Indenture equally and proportionately with any and all
other Securities duly issued hereunder.





                                       20
<PAGE>   27
   The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

   Interest on any Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest.

   Any interest on any Security which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in Clause (1) or (2) below:

   (1) the Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest, which shall be fixed in the
following manner.  The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security and the date
of the proposed payment, and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this Clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment.  The Trustee
shall promptly notify the Company of such Special Record Date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder at his address as it appears in the
Security Register, not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Securities (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause
(2).

   (2) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and, if so listed, upon such notice as
may be required by such exchange, if, after notice given by the Company to the
Trustee of the proposed payment pursuant to this clause, such manner of payment
shall be deemed practicable by the Trustee.

<PAGE>   28
   Subject to the foregoing provisions of this Section, each Security delivered
under this Indenture upon registration of transfer of or in exchange for or in
lieu of any other Security shall carry the rights to interest accrued and
unpaid, and to accrue (including in each such case Additional Interest), which
were carried by such other Security.

SECTION 308.  Persons Deemed Owners.

   Prior to due presentment of a Security for registration of transfer, the
Company, the Guarantor, the Trustee and any agent of any of them shall treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 307) interest (including Additional Interest) on such Security and for
all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Guarantor, the Trustee nor any agent of them shall be
affected by notice to the contrary.

SECTION 309.  Cancellation.

   All Securities surrendered for payment, redemption, registration of transfer
or exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it.  The Company or
the Guarantor may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
or the Guarantor may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly cancelled by the Trustee.  No Securities shall
be authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture.  All
cancelled Securities held by the Trustee shall be disposed of as directed by a
Company Order.

SECTION 310.  Computation of Interest.

   Interest on the Securities shall be computed on the basis of a 360-day year
of twelve 30-day months.

expressly provided for and any amounts owed to the Trustee hereunder), and the
Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when

         arrangements satisfactory to the Trustee for thegiving of notice of

complied with.  Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Company to the Trustee under Section 607 and,
if money shall have been deposited with the Trustee pursuant to subclause (B)
of Clause (1) of this Section, the obligations of the Trustee under Section 402
and the last paragraph of Section 1003 shall survive.

                                    Remedies

SECTION 501.  Events of Default.

   "Event of Default", wherever used herein, means any one of the following
events that has occurred and is continuing (whatever the reason for such Event
of Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

   (1) failure for 90 days to pay any interest on the Securities, including any
Additional Interest in respect thereof, when due (subject to the deferral of
any due date in the case of an Extension Period); or

   (2) failure to pay any principal on the Securities when due whether at
Stated Maturity, upon redemption by declaration or otherwise; or

   (3) failure to observe or perform in any material respect any other covenant
herein for 90 days after written notice of such failure (specified as a "Notice
of Default"), requiring the Company to remedy the same shall have been given to
the Company and the Guarantor by the Trustee or the holders of at least 25% in
principal amount of the Outstanding Securities; or

   (4) a court or governmental agency having jurisdiction in the premises shall
enter a decree or order for relief in respect of the Company or the Guarantor
in an involuntary case under any applicable federal or state bankruptcy,
insolvency or other similar law now or hereafter in effect, or appointing a
receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar
official) of the Company or the Guarantor or for all or substantially all of
its property or ordering the winding up or liquidation of its affairs, and such
decree or order shall remain unstayed and in effect for a period of 90
consecutive days; or

   (5) the Company or the Guarantor shall commence a voluntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or consent to the entry of an order for relief in an involuntary case
under any such law, or consent to the appointment or taking possession by a
receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar
official) of the Company or the Guarantor or for all or substantially all of
its property or make any general assignment for the benefit of creditors; or
the Company or the Guarantor shall admit in writing its inability to pay its
debts generally as they become due.

SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

   If an Event of Default occurs and is continuing, then and in every such case
the Trustee or the Holders of not less than 25% in aggregate principal amount
of the Outstanding Securities shall have the right to declare the principal of
and the interest on all the Securities (including any Additional Interest) and
any other amounts payable hereunder to be due and payable immediately,





                                       24
<PAGE>   31
by a notice in writing to the Company and the Guarantor (and to the Trustee if
given by Holders) and to enforce any and all other rights of Holders of
Securities as creditors with respect to the Securities.  Upon any such
declaration such principal and all accrued interest shall become immediately
due and payable.

   At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter provided in this Article, the Holders of a majority
in principal amount of the Outstanding Securities, by written notice to the
Company and the Guarantor and the Trustee, may rescind and annul such
declaration and its consequences if:

   (1) the Company or the Guarantor has paid or deposited with the Trustee a
sum sufficient to pay,

         (A) all overdue interest (including any Additional Interest) on all
Securities,

         (B) the principal of any Securities which have became due otherwise
than by such declaration of acceleration and interest thereon at the rate borne
by the Securities, and

         (C) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel;

and

   (2) all Events of Default, other than the non-payment of the principal of
Securities which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 513.

   No such rescission shall affect any subsequent default or impair any right
consequent thereon.  SECTION 503.  Collection of Indebtedness and Suits for
Enforcement by Trustee.

   The Company covenants that if

   (1) default is made in the payment of any interest (including any Additional
Interest) on any Security when such interest becomes due and payable and such
default continues for a period of 90 days (subject to the deferral of any due
and payable interest in the case of an Extension Period), or

   (2) default is made in the payment of the principal of any Security at the
Maturity thereof, the Company will, upon demand of the Trustee, pay to it, for
the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal and interest (including any Additional
Interest), at the rate borne by the Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the





                                       25
<PAGE>   32
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

   If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504.  Trustee May File Proofs of Claim.

   In case of any judicial proceeding relative to the Company or the Guarantor,
its property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise, to take any and all actions
authorized under the Trust Indenture Act in order to have claims of the Holders
and the Trustee allowed in any such proceeding.  In particular, the Trustee
shall be authorized to collect and receive any moneys or other property payable
or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 607.

   No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.

   All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.  Application of Money Collected.

SECTION 507.  Limitation on Suits.

   No Holder of any Security shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment
of a receiver or trustee, or for any other remedy hereunder, unless

   (1) such Holder has previously given written notice to the Trustee of a
continuing Event of Default;

   (2) the Holders of not less than 25% in principal amount of the Outstanding
Securities shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee
hereunder;

   (3) such Holder or Holders have offered to the Trustee such indemnity as is
satisfactory to it against the costs, expenses and liabilities to be incurred
in compliance with such request;

   (4) the Trustee for 60 days after its receipt of such notice, request and
offer of indemnity has failed to institute any such proceeding; and

   (5) no direction inconsistent with such written request has been given to
the Trustee during such 60-day period by the Holders of a majority in principal
amount of the Outstanding Securities; it being understood and intended that no
one or more Holders shall have any right in any manner whatever by virtue of,
or by availing of, any provision of this Indenture to affect, disturb or
prejudice the rights of any other Holders, or to obtain or to seek to obtain
priority or preference over any other Holders or to enforce any right under
this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all the Holders.

Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and (subject to Section 307) interest (including
any Additional Interest) on such Security on the respective Stated Maturities
(subject to the deferral of any due date in the case of an Extension Period)
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the





                                       27
<PAGE>   34
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

SECTION 509.  Restoration of Rights and Remedies.

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

SECTION 510.  Rights and Remedies Cumulative.

   Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.  SECTION 511.  Delay or Omission Not Waiver.

   No delay or omission of the Trustee or of any Holder of any Security to
exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 512.  Control by Holders.

   The Holders of a majority in principal amount of the Outstanding Securities
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee, provided that

   (1) such direction shall not be in conflict with any rule of law or with
this Indenture; and

   (2) the Trustee may take any other action deemed proper by the Trustee which
is not inconsistent with such direction.

SECTION 513.  Waiver of Past Defaults.

   Subject to Section 902, the Holders of not less than a majority in principal
amount of the Outstanding Securities may on behalf of the Holders of all the
Securities waive any past default hereunder and its consequences, except a
default

   (1) in the payment of the principal of or interest (including any Additional
Interest) on any Security (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration have been deposited with the Trustee); or

   (2) in respect of a covenant or provision hereof which under Article Nine
cannot be modified or amended without the consent of the Holder of each
Outstanding Security affected.

   Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

it as Trustee, a court may require any party litigant in such court to file an
undertaking to pay the costs of such suit, and may assess costs against any
such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to
make such an assessment in any suit instituted by the Company or the Trustee or
in any suit for the enforcement of the right to receive the principal of and
interest (including any Additional Interest) on any Security.

SECTION 515.  Acknowledgement.

permitted by law on behalf of the Partnership, when and as provided in the

the Company under this Indenture or against the Guarantor under the Guarantee,
without first instituting any legal proceeding against the Property Trustee (as
such term is defined in the Limited Partnership Agreement) or any other party.

conclusively rely upon an Officers' Certificate;

authorization and protection in respect of any action taken, suffered or

risk its own funds or otherwise incur financial liability in the performance of

if it shall have reasonable grounds to believe that repayments of such funds or
indemnity satisfactory to it against any loss, liability or expense is not
reasonably assured to it.

   (j)   The Trustee shall have no duty to monitor the performance of the
Company or the Guarantor or their compliance with the covenants contained
herein, nor shall it have any liability in connection with the malfeasance or
nonfeasance by such parties.

   The Company and the Guarantor agree

   (1) to pay to the Trustee from time to time such reasonable compensation as

be limited by any provision of law in regard to the compensation of a trustee
of an express trust);

   (2) except as otherwise expressly provided herein, to reimburse the Trustee
upon its request for all reasonable fees, charges, expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provision of

out of or in connection with the acceptance or administration of this trust,
including the costs and expenses of defending themselves against any claim or

SECTION 608.  Disqualification; Conflicting Interests.

combined capital and surplus of at least $50,000,000 and has its Corporate
Trust Office in New York, New York, if such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Person shall be deemed to be its combined

<PAGE>   40
then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.

Holders and accepted appointment in the manner hereinafter provided, any Holder
who has been a bona fide Holder of a Security for at least six months may, on

of any successor Trustee.

SECTION 611.  Acceptance of Appointment by Successor.

deliver to the Company, to the Guarantor and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; provided that, on
request of the Company, the Guarantor or the successor Trustee, such retiring
Trustee shall, upon payment of its fees, charges and expenses, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder.  Upon request of any such successor Trustee, the Company and

administration under any bankruptcy law or law relating to creditors' rights
generally.

              Consolidation, Merger, Conveyance, Transfer or Lease

SECTION 801.  Company or Guarantor May Consolidate, Etc., Only on Certain
              Terms.

   Each of the Company and the Guarantor covenants that it will not merge or
consolidate with any other corporation or other entity or sell or convey all or
substantially all of its assets to any person (other than such a sale or
conveyance to a Subsidiary or any successor thereto (such a sale or conveyance
being called an "Asset Drop-Down")), unless (i) either the Company or the
Guarantor shall be the continuing corporation or the successor corporation or
other entity or the person which acquires by sale or conveyance substantially
all the assets of the Company or the Guarantor shall expressly assume the due
and punctual payment of the principal of, premium, if any, and interest, if
any, on all the Securities, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed or observed by the Company or the Guarantor, by
supplemental indenture in form satisfactory to the Trustee, executed and
delivered to the Trustee by such corporation or other entity, and (ii) the
Company, the





                                       36
<PAGE>   43
Guarantor or such successor corporation or other entity, as the case may be,
shall not, immediately after such merger or consolidation, or such sale or
conveyance, be in default in the performance of any such covenant or condition.
In the event of any Asset Drop-Down after the date of this Indenture, any
subsequent sale or conveyance of assets by a Subsidiary to which assets were
transferred in such Asset Drop-Down (a "Drop-Down Subsidiary") will be deemed
to be a sale or conveyance of assets by the Company or the Guarantor for
purposes of this Section 801.

SECTION 802.  Successor Substituted.

   In case of any such consolidation, merger, sale or conveyance, and following
such an assumption by the successor corporation, such successor corporation
shall succeed to and be substituted for the Company or the Guarantor, with the
same effect as if it had been named herein.  Such successor corporation may
cause to be signed, and may issue either in its own name or in the name of the
Company or the Guarantor prior to such succession any or all of the Securities
issuable hereunder which theretofore shall not have been signed by the Company
and guaranteed by the Guarantor and delivered to the Trustee; and, upon the
order of such successor corporation instead of the Company or the Guarantor and
subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver any Securities
which previously shall have been signed and delivered by the officers of the
Company and the Guarantor  to the Trustee for authentication, and any
Securities which such successor corporation thereafter shall cause to be signed
and delivered to the Trustee for that purpose.  All of the Securities so issued
shall in all respects have the same legal rank and benefit under this Indenture
as the Securities theretofore or thereafter issued in accordance with the terms
of this Indenture as though all of such Securities had been issued at the date
of the execution hereof.

   In case of any such consolidation, merger, sale, lease or conveyance such
changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

   In the event of any such sale or conveyance (other than a conveyance by way
of lease) the Company, the Guarantor or any successor corporation which shall
theretofore have become such in the manner described in this Article shall be
released and discharged from all obligations and covenants under this
Indenture.

Indenture with respect to the subordination of the Securities in a manner
adverse to the Holders,

   (2) reduce the percentage in principal amount of the Outstanding Securities,

increase any such percentage or to provide that certain other provisions of
this Indenture cannot be modified or waived without the consent of the Holder
of each Outstanding Security affected thereby.

   It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

SECTION 903.  Execution of Supplemental Indentures.

   In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to

an officer's stating that Certificate precedent to the execution of such
supplemented indenture have been fulfilled and an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by
this Indenture.  The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

SECTION 904.  Effect of Supplemental Indentures.

   Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental

                   Covenants; Representations and Warranties

SECTION 1001.  Payment of Principal and Interest.

   The Company will duly and punctually pay the principal of and interest on
the Securities in accordance with the terms of the Securities and this
Indenture.

SECTION 1002.  Maintenance of Office or Agency.

   The Company will maintain in the United States an office or agency where
Securities may be presented or surrendered for payment, where Securities may be
surrendered for registration of transfer or exchange, where Securities may be
surrendered for conversion and where notices and demands to or upon the Company
in respect of the Securities and this Indenture may be served.  The Company
will give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency.  If at any time the Company shall
fail to maintain any such required office or agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices
and





                                       39
<PAGE>   46
demands may be made or served at the Corporate Trust Office of the Trustee, and
the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

   The Company may also from time to time designate one or more other offices
or agencies (in the United States) where the Securities may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall
in any manner relieve the Company of its obligation to maintain an office or
agency in the United States for such purposes.  The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

SECTION 1003.  Money for Security Payments to Be Held in Trust.

   If the Company shall at any time act as its own Paying Agent, it will, on or
at the option of the Company before each due date of the principal of or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Persons entitled thereto a sum sufficient to pay the principal or
interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

   Whenever the Company shall have one or more Paying Agents, it will, on or
prior to each due date of the principal of or interest on any Securities,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

   Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or interest on any
Security and remaining unclaimed for two years after such principal or interest
has become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease.

SECTION 1004.  Reports by the Company.

   The Guarantor shall file with the Trustee and the Commission, and transmit
to Holders, such information, documents and other reports, and such summaries
thereof, as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant to such Act; provided that any such
information, documents or reports required to be filed with the Commission
pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 shall be
filed with the Trustee within





                                       40
<PAGE>   47
15 days after the same is so required to be filed with the Commission.
Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's or the
Guarantor's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

SECTION 1005.  Negative Pledge and Exceptions Thereto.

   So long as any of the Securities are outstanding, the Company will not
pledge, mortgage or hypothecate, or permit to exist, and will not cause, suffer
or permit any Subsidiary to pledge, mortgage or hypothecate, or permit to
exist, except in favor of the Company or any Subsidiary, any mortgage, pledge
or other lien upon, any Principal Property at any time owned by it, to secure
any indebtedness, without making effective provisions whereby the Securities
shall be equally and ratably secured with any and all such indebtedness and
with any other indebtedness similarly entitled to be equally and ratably
secured; provided, however, that this restriction shall not apply to or prevent

   interests, production payments and other similar interests, wellhead
   production equipment, tanks, field gathering lines, leasehold or field

         (i)     any mortgage, pledge, lien or encumbrance on oil, gas, natural

   interest in which is owned or leased by the Company or a Subsidiary;

         (j)     mortgages, pledges, liens or encumbrances upon any property
   heretofore or hereafter acquired, created at the time of acquisition or
   within one year thereafter to secure all or a portion of the purchase price
   thereof, or existing thereon at the date of acquisition, whether or not
   assumed by the Company or a Subsidiary, provided that every such mortgage,
   pledge, lien or encumbrance shall apply only to the property so acquired and
   fixed improvements thereon;

         (k)     any extension, renewal or refunding, in whole or in part, of
   any mortgage, pledge, lien or encumbrance permitted by subparagraph (j)
   above, if limited to the same property or any portion thereof subject to,
   and securing not more than the amount secured by, the mortgage, pledge, lien

         (l)     mortgages, pledges, liens or encumbrances upon any property

   to the time the Acquired Entity becomes a Subsidiary or (B) be created at
   the time the Acquired Entity becomes a Subsidiary or within one year
   thereafter to secure all or a portion of the acquisition price thereof and

   connection with the financing of the





                                       42
<PAGE>   49
   acquisition or construction of property to be used in the business of the
   Company or a Subsidiary or as required by law or governmental regulation as

         (q)     any mortgage, pledge, lien or encumbrance of or upon any
   office equipment, data processing equipment (including, without limitation,

         (r)     any mortgage, pledge, lien or encumbrance created or assumed

   holder of such security pursuant to the Internal Revenue Code of 1954, as
   amended, for the purpose of financing, in whole or in part, the acquisition
   or construction of property to be used by the Company or a Subsidiary; or

         (s)     the pledge or assignment of accounts receivable, or the pledge
   or assignment of conditional sales contracts or chattel mortgages and
   evidences of indebtedness secured thereby, received in connection with the
   sale by the Company or such Subsidiary or others of goods or merchandise to
   customers of the Company or such Subsidiary.

   In case the Company or any Subsidiary shall propose to pledge, mortgage or
hypothecate any Principal Property at any time owned by it to secure any
indebtedness, other than as permitted by subdivisions (a) to (s), inclusive, of
this Section 1005, the Company (i) will prior thereto give written notice
thereof to the Trustee, and (ii) will, or will cause such Subsidiary to, prior

Securities equally and ratably with such indebtedness.

   Notwithstanding the foregoing provisions of this Section 1005, the Company
or a Subsidiary may issue, assume or guarantee indebtedness secured by mortgage
which would otherwise be subject to the foregoing restrictions in an aggregate
amount which, together with all other indebtedness of the Company or a
Subsidiary secured by a mortgage which (if originally issued, assumed or
guaranteed at such time) would otherwise be subject to the foregoing
restrictions (not including indebtedness permitted to be secured under clauses
(a) through (s) above), does not at the time exceed 10% of the Consolidated Net
Tangible Assets of the Company, as shown on the audited consolidated financial
statements of the Company as of the end of the fiscal year preceding the date
of determination.

SECTION 1006.  Statement as to Compliance; Notice of Certain Events of Default.

   Each of the Company and the Guarantor will, within 120 days after the close
of each fiscal year, commencing with the first fiscal year following the
issuance of Securities under this Indenture, file with the Trustee a
certificate of the principal executive officer, the principal financial officer
or the principal accounting officer of the Company and the Guarantor covering
the period from the date of issuance of such Securities to the end of the
fiscal year in which such Securities were issued, in the case of the first such
certificate, and covering the preceding fiscal year in the case of each
subsequent certificate, and stating whether or not, to the knowledge of the
signer, each of the Company and the Guarantor has complied with all conditions
and covenants on its part contained in this Indenture, and, if the signer has
obtained knowledge of any default by the Guarantor in the performance,
observance or fulfillment of any such condition or covenant, specifying each
such default and the nature thereof.  For the purpose of this Section 1007,
compliance shall be determined without regard to any grace period or
requirement of notice provided pursuant to the terms of this Indenture.

                                   Guarantee

SECTION 1101.  Securities Entitled to Guarantee.

Guarantee provided for by the Guarantor in accordance with the terms thereof.

                                 ARTICLE TWELVE

                            Redemption of Securities

SECTION 1201.  Optional Redemption.

   (a) At any time on or after December 31, 2001, the Company shall have the
right to redeem the Securities, in whole or in part, from time to time, at a
Redemption Price equal to 100% of the principal amount of Securities to be
redeemed plus accrued but unpaid interest, including any Additional Interest,
if any, to the Redemption Date.

   (b) If, at any time, a Partnership Tax Event or a Partnership Investment
Company Event (each a "Partnership Special Event") shall occur and be
continuing, the Company may, within 90 days following the occurrence of such
Partnership Special Event, elect to redeem the Securities in whole (but not in
part), upon not less than 30 or more than 60 days' notice at the Redemption
Price, provided that, if at the time there is available to the Company or the
Partnership the opportunity to eliminate, within such 90-day period, the
Partnership Special Event by taking some ministerial action, such as filing a
form or making an election, or pursuing some other similar reasonable such
measure that in the sole judgment of the Company has or will cause no adverse
effect on the





                                       44
<PAGE>   51
Partnership, the Trust or the Company, the Company will pursue such measure in
lieu of redemption.

SECTION 1202. Mandatory Redemption.

   If, at any time, a Change of Control shall occur and be continuing, the
Company shall, as promptly as practicable (and in any event within 90 days
following the occurrence of such Change of Control), redeem the Securities in
whole (but not in part), upon not less than 30 or more than 60 days' notice at
the Redemption Price.  As promptly as practicable following a Change of
Control, the Company or the Guarantor shall provide written notice to the
Trustee of such Change of Control.

SECTION 1203.  Applicability of Article.

   Redemption of Securities, at the election of the Company as permitted by
Section 1201, shall be made in accordance with such provision and this Article.

SECTION 1204.  Authorization for Redemption; Notice to Trustee.

   The election of the Company to redeem Securities pursuant to Section 1201
shall be evidenced by a Board Resolution.  In case of any redemption, the
Company shall, at least 30 days and no more than 60 days prior to the
Redemption Date fixed by the Company, notify the Trustee of such Redemption
Date and of the principal amount of Securities to be redeemed and provide a
copy of the notice of redemption given to Holders of Securities to be redeemed
pursuant to Section 1204.

SECTION 1205.  Selection by Trustee of Securities to Be Redeemed.

   If less then all the Securities are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities not previously called for redemption, by such
method (including pro rata or by lot) as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to $25 or any integral multiple thereof) of the principal amount of the
Securities.

   The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected
for partial redemption as aforesaid, the principal amount thereof to be
redeemed.

   The provisions of the two preceding paragraphs shall not apply with respect
to any redemption affecting only a single Security, whether such Security is to
be redeemed in whole or in part.  In the case of any such redemption in part,
the unredeemed portion of the principal amount of the Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.

   For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be





                                       45
<PAGE>   52
redeemed only in part, to the portion of the principal amount of such
Securities which has been or is to be redeemed.

SECTION 1206.  Notice of Redemption.

   Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

   All notices of redemption shall identify the Securities to be redeemed and
shall state:

   (1) the Redemption Date,

   (2) the Redemption Price,

   (3) that on the Redemption Date the Redemption Price will become due and
payable upon each such security to be redeemed and that interest thereon will
cease to accrue on and after said date, and

   (4) the place or places where such securities are to be surrendered for
payment of the Redemption Price.

   Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1207.  Deposit of Redemption Price.

   Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

SECTION 1208.  Securities Payable on Redemption Date.

   Notice of redemption having been given as aforesaid, the Securities so to be
redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such





                                       46
<PAGE>   53
at the close of business on the relevant Record Dates according to their terms
and the provisions of Section 307.

   If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid, bear interest from the
Redemption Date at the rate borne by the Security.

SECTION 1209.  Securities Redeemed in Part.

   Any Security which is to be redeemed only in part shall be surrendered at a
place of payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company, the Guarantor and the Trustee duly executed by, the Holder thereof or
his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Security or Securities, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal
to and in exchange for the unredeemed portion of the principal of the Security
so surrendered.  The Company may not redeem fewer than all the Outstanding
Securities unless all accrued and unpaid interest (including Additional
Interest) has been paid on such Securities.

   This instrument may be executed in any number of counterparts, each of which
so executed shall be deemed to be an original, but all such counterparts shall
together constitute but one and the same instrument.

         definitions herein relating thereto;

                    (2)   a brief statement as to the nature and scope of the

         contained in such certificate or opinion are based;

it relates to factual





                                       8
<PAGE>   15
matters, upon a certificate or opinion of, or representations by, an officer or
officers of the Company stating that the information with respect to such
factual matters is in the possession of the Company, unless such counsel knows,
or in the exercise of reasonable care should know, that the certificate or
opinion or representations with respect to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form any instrument.

SECTION 104.  Acts of Holders; Record Dates.

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company
and/or the Guarantor.  Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Holders signing such instrument or instruments.  Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 601) conclusive in
favor of the Trustee and the Company and the Guarantor, if made in the manner
provided in this Section.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

         (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining
the Holders entitled to give or take any request, demand, authorization,
direction, notice, consent, waiver or other action, or to vote on any action,
authorized or permitted to be given or taken by Holders.  If not set by the
Company prior to the first solicitation of a Holder made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be.  With regard to any record date, only the Holders on such date (or
their duly designated proxies) shall be entitled to give or take, or vote on,
the relevant action.

         (d) The ownership of Securities shall be proved by the Security
Register.





                                       9
<PAGE>   16
         (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made
upon such Security.

SECTION 105.  Notices, Etc., to Trustee, the Company and the Guarantor.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1) the Trustee by any Holder or by the Company or the Guarantor shall
be sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, Global Trust
Services, or

         (2) the Company or the Guarantor by the Trustee or by any Holder shall
be sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to the Company
or the Guarantor addressed to it at the address of its principal office
specified below or at any other address previously furnished in writing to the
Trustee by the Company or the Guarantor, as the case may be.

         If to the Company or the Guarantor to:

                    Enron Corp.
                    1400 Smith Street
                    Houston, Texas 77002
                    Attention: Treasurer

SECTION 106.  Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in a
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed
with the Trustee, but such filing shall not be a condition precedent to the
validity of any action taken in reliance upon such waiver.





                                       10
<PAGE>   17
         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

SECTION 107.  Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall
be deemed to apply to this Indenture as so modified or to be excluded, as the
case may be.

SECTION 108.  Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

SECTION 109.  Successors and Assigns.

         The Company will have the right at all times to assign any of its
rights or obligations under this Indenture to a direct or indirect wholly-owned
Subsidiary, provided that, in the event of any such assignment, the Company
will remain liable for all such obligations.  Subject to the foregoing, this
Indenture is binding upon and inures to the benefit of the parties hereto and
their respective successors and assigns. This Indenture may not otherwise be
assigned by the parties hereto.

SECTION 110.  Separability Clause.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.


SECTION 111.  Benefits of Indenture.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness, the holders of Preferred
Securities (to the extent provided herein) and the Holders of Securities, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 112.  Governing Law.

         THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

SECTION 113.  Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of interest or
principal of the Securities shall be made on the next succeeding day which 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 of interest or principal of the Securities, as the case may
be, shall be made on the immediately preceding Business Day, in each case, with
the same force and effect as if made on the Interest Payment Date or Redemption
Date, or at the Stated Maturity and with no reduction in interest or principal
in respect of such early payment.

                                 Security Forms

SECTION 201.  Forms Generally.

         The Securities and the Trustee's certificates of authentication shall
be in substantially the forms set forth in this Article, with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture, and may have such letters, numbers or other marks
of identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities,
as evidenced by their execution of the Securities.

         The definitive Securities shall be printed, lithographed or engraved
or produced by any combination of these or other methods, all as determined by
the officers executing such Securities, as evidenced by their execution of such
Securities.

No. _____________                                                      $________

         Enron Capital & Trade Resources Corp, a corporation duly organized and
existing under the laws of the State of Delaware (herein called the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to ________________,
or registered assigns, the principal sum of ________ DOLLARS ($________) on
September 30, 2016 and to pay interest on said principal sum from November 21,
1996 or from the most recent interest payment date (each such date, an
"Interest Payment Date") to which interest has been paid or duly provided for,
quarterly (subject to deferral as set forth herein)





                                       12
<PAGE>   19
in arrears on March 31, June 30, September 30 and December 31 of each year,
commencing December 31, 1996, at the rate of 7.75% per annum plus Additional
Interest, if any, until the principal hereof shall have become due and payable,
and on any overdue principal. The amount of interest payable for any period
will be computed on the basis of twelve 30-day months and a 360-day year.  In
the event that any date on which interest is payable on this Security is not a
Business Day, then a payment of the interest payable on such date will be made
on the next succeeding day which is a Business Day (and without any interest or
other payment in respect of any such delay), except that, if such Business Day
is in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on the date the payment was originally payable.  A "Business Day"
shall mean any day other than a day on which banking institutions in the City
of New York are authorized or required by law to remain closed.  The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the Person
in whose name this Security (or one or more Predecessor Securities, as defined
in the Indenture) is registered at the close of business on the Regular Record
Date for such interest installment, which shall be the close of business on the
Business Day next preceding such Interest Payment Date.  Any such interest
installment not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date and may either be paid
to the Person in whose name this security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in said Indenture.

         The Company shall have the right at any time during the term of this
Security, from time to time, to extend the interest payment period of such
Security for up to six consecutive quarters (an "Extension Period"), during
which periods interest will compound quarterly and the Company shall have the
right to make partial payments of interest on any Interest Payment Date, and at
the end of which Extension Period the Company shall pay all interest then
accrued and unpaid (together with Additional Interest thereon to the extent
that payment of such interest is permitted by applicable law).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that such Extension Period together with all
such previous and further extensions thereof shall not exceed six consecutive
quarters or extend beyond the Maturity of this Security.  Upon the termination
of any such Extension Period and upon the payment of all accrued and unpaid
interest and any Additional Interest then due, the Company may select a new
Extension Period, subject to the foregoing requirements.  No interest shall be
due and payable during an Extension Period except at the end thereof.  The
Company shall give the Holder of this Security and the Trustee written notice
of its selection of an Extension Period at least one Business Day prior to the
earlier of (i) the Interest Payment Date or (ii) the date Enron Capital Trust I
is required to give notice to the New York Stock Exchange or other applicable
self-regulatory organization or to holders of the Trust Preferred Securities of
the record date or the date such distributions are payable, but in any event
not less than one Business Day prior to such record date.





                                       13
<PAGE>   20
         Payment of the principal of and interest on this Security will be made
at the office or agency of the Company maintained for that purpose in New York,
New York, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
made (i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Security
Register.

         Reference is hereby made to the further provisions of the Indenture
summarized on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this
Security shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

         IN WITNESS WHEREOF, Enron Capital & Trade Resources Corp. has caused
this instrument to be duly executed under its corporate seal.

SECTION 203.  Form of Reverse of Security.

         This Security is one of a duly authorized issue of Securities of the
Company, designated as its 7.75% Debentures Due 2016 (herein called the
"Securities"), limited in aggregate principal amount to $29,108,000 issued
under an Indenture, dated as of November 21, 1996 (herein called the
"Indenture"), among the Company, Enron Corp., as Guarantor (herein called the
"Guarantor, which term includes any successor corporation that shall become the
Guarantor under the Indenture) and The Chase Manhattan Bank, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Trustee, the Company, the
Guarantor and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.





                                       14
<PAGE>   21
         At any time on or after December 31, 2001, the Company shall have the
right, subject to the terms and conditions of Article Twelve of the Indenture,
to redeem this Security at the option of the Company, without premium or
penalty, in whole or in part, at a Redemption Price equal to 100% of the
principal amount to be redeemed plus accrued but unpaid interest, including any
Additional Interest, if any, to the Redemption Date.  If a Partnership Special
Event shall occur and be continuing, the Company shall have the right, subject
to the terms and conditions of Article Twelve of the Indenture, to redeem this
Security, without premium or penalty, in whole but not in part, at a Redemption
Price equal to 100% of the principal amount thereof plus accrued but unpaid
interest, including any Additional Interest, if any, to the Redemption Date.
Any redemption pursuant to this paragraph will be made upon not less than 30
nor more than 60 days' notice, at the Redemption Price.  If the Securities are
only partially redeemed by the Company, the Securities will be redeemed pro
rata, by lot or in such other manner as the Trustee shall deem appropriate and
fair in its discretion and that may provide for the selection of a portion or
portions (equal to twenty-five U.S. dollars ($25) or any integral multiple
thereof) of the principal amount of any Security.

         In the event of redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

         If an Event of Default with respect to the Securities shall occur and
be continuing, the principal of the Securities may be declared due and payable
in the manner, with the effect and subject to the conditions provided in the
Indenture.

         The Indenture contains provisions for satisfaction and discharge at
any time of the entire indebtedness of this Security upon compliance by the
Company with certain conditions set forth in the Indenture.

         The Indenture contains provisions permitting the Company or the
Guarantor and the Trustee, with the consent of Holders of not less than a
majority in principal amount of the Outstanding Securities, to modify the
Indenture in a manner affecting the rights of the Holders of the Securities;
provided that no such modification may, without the consent of the Holder of
each Outstanding Security, (i) extend the fixed maturity of the Securities, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, or (ii) reduce the percentage of principal amount of the Securities,
the Holders of which are required to consent to any such modification of the
Indenture.  The Indenture also contains provisions permitting Holders of
specified percentages in principal amount of the Securities at the time
Outstanding, on behalf of the Holders of all Securities, to waive compliance by
the Company or the Guarantor with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences.  Any such
consent or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the





                                       15
<PAGE>   22
principal of and interest on this Security at the times, place and rate, and in
the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in New York, New York, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities,
of authorized denominations and for the same aggregate principal amount, will
be issued to the designated transferee or transferees.  No service charge shall

transfer, the Company, the Guarantor, the Trustee and any of their respective

denominations of $25 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

                                 The Securities

SECTION 301.  Title and Terms.

         The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $29,108,000,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other securities pursuant to Section
303, 304, 305, 306, 906 or 1209.

         The Securities shall be known and designated as the "7.75% Debentures
Due 2016" of the Company.  Their Stated Maturity shall be September 30, 2016,
and they shall bear interest at the rate of 7.75% per annum, from November 21,
1996 or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, as the case may be, payable quarterly (subject to
deferral as set forth herein), in arrears, on March 31, June 30, September 30
and December 31 of each year, commencing December 31, 1996 until the principal
thereof is paid or made available for payment.  Interest will compound
quarterly and will accrue at the rate of 7.75% per annum on any interest
installment in arrears for more than one quarter or during an extension of an
interest payment period as set forth below in this Section 301.  In the event
that any date on which interest is payable on the Securities is not a Business
Day, then a payment of the interest payable on such date will be made on the
next succeeding day which is a Business Day (except that, if such Business Day
is in the next succeeding calendar year, such Interest Payment Date shall be
the immediately preceding Business Day) (and without any interest or other
payment in respect of any such delay).

         The Company shall have the right, at any time during the term of the
Securities, from time to time to extend the interest payment period for up to
six consecutive quarters (the "Extension Period") during which period interest
will compound quarterly and the Company shall have the right to make partial
payments of interest on any Interest Payment Date, and at the end of which
Extension Period the Company shall pay all interest then accrued and unpaid
thereon (together with Additional Interest at the rate specified for the
Securities to the extent permitted by applicable law).  Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that such Extension Period together with all
such previous and further extensions thereof shall not exceed six consecutive
quarters or extend beyond the Maturity of the Securities.  Upon the termination
of any Extension Period and upon the payment of all accrued and unpaid interest
and any Additional Interest then due, the Company may select a new Extension
Period, subject to the foregoing requirements.  No interest shall be due and
payable during an Extension Period, except at the end thereof.  The Company
shall give the Trust, the Partnership and the Trustee notice of its selection
of such Extension Period subject to the above requirements at least one
Business Day prior to the earlier of (i) the Interest Payment Date or (ii) the
date the Trust is required to give notice to the New York Stock Exchange or
other applicable self-regulatory organization or to holders of the Trust
Preferred Securities of the record date or the date such distributions are
payable, but in any event not less than one Business Day prior to such record
date.

         The principal of and interest on the Securities shall be payable at
the office or agency of the Company in the United States maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made (i)
by check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register or (ii) by wire transfer in immediately
available funds at such place and to such account as may be designated by the
Person entitled thereto as specified in the Security Register.

         The Securities shall be guaranteed by the Guarantor as provided in
Article Eleven.

         The Securities shall be redeemable as provided in Article Twelve.

SECTION 302.  Denominations.

         The Securities shall be issuable only in registered form, without
coupons, and only in denominations of $25 and any integral multiple thereof.

SECTION 303.  Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of the Company by its
Chairman, one of its Vice Chairman, its President, one of its Managing
Directors or one of its Vice Presidents.  The signature of any of these
officers on the securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

SECTION 304.  Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

         If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities
of authorized denominations.  Until so exchanged the temporary Securities shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

SECTION 305.  Registration, Registration of Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant Section 1002 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 1002 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate
principal amount.

         At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at such office or
agency.  Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

         All Securities issued upon any registration of transfer or excess of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written





                                       19
<PAGE>   26
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1209 not involving any transfer.

         If the Securities are to be redeemed in part, the Company will not be
required to issue, register the transfer of or exchange any Securities during a
period beginning at the opening of business 15 days before the day of mailing
of a notice of redemption of any such Securities that may be selected for
redemption and ending at the close of business on the day of such mailing,
except the unredeemed portion of any such Securities being redeemed in part.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
security and (ii) such security or indemnity as may be required by them to save
each of them and any of their officers, directors, employees or agents of
either of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and the Trustee shall authenticate and deliver, in lieu
of any such destroyed, lost or stolen Security, a new Security of like tenor
and principal amount and bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.





                                       20
<PAGE>   27
         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

         Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

         (1) the Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest, which shall be fixed in the
following manner.  The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security and the date
of the proposed payment, and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this Clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment.  The Trustee
shall promptly notify the Company of such Special Record Date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment
of such Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder at his address as it appears in the
Security Register, not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Securities (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause
(2).

         (2) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be listed, and, if so listed, upon such
notice as may be required by such exchange, if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue (including in each such case Additional Interest),
which were carried by such other Security.

SECTION 308.  Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Guarantor, the Trustee and any agent of any of them shall
treat the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 307) interest (including Additional Interest) on such Security and for
all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Guarantor, the Trustee nor any agent of them shall be
affected by notice to the contrary.


SECTION 309.  Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and shall be promptly cancelled by it.
The Company or the Guarantor may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company or the Guarantor may have acquired in any manner whatsoever,
and all Securities so delivered shall be promptly cancelled by the Trustee.  No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture.  All cancelled Securities held by the Trustee shall be disposed of
as directed by a Company Order.

SECTION 310.  Computation of Interest.

         Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

SECTION 401.  Satisfaction and Discharge of Indenture.

         This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for and any amounts owed to the Trustee hereunder), and the
Trustee, on demand of and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when

whose payment money has theretofore been deposited in trust or segregated and

Trustee for cancellation

                          (i) have become due and payable,

                          (ii) will become due and payable at their Stated

         has deposited or caused to be deposited with the Trustee as trust
         funds in trust for the purpose and amount sufficient to pay and
         discharge the entire indebtedness on such Securities not theretofore
         delivered to the Trustee for cancellation, for principal and interest
         (including Additional Interest) to the date of such deposit (in the
         case of Securities which have become due and payable) or to the
         StatedMaturity or Redemption Date, as the case may be;

         (2)  the Company has paid or caused to be paid all other sums payable

                                    Remedies

SECTION 501.  Events of Default.

         "Event of Default", wherever used herein, means any one of the
following events that has occurred and is continuing (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or
governmental body):

         (1) failure for 90 days to pay any interest on the Securities,
including any Additional Interest in respect thereof, when due (subject to the
deferral of any due date in the case of an Extension Period); or

         (2) failure to pay any principal on the Securities when due whether at
Stated Maturity, upon redemption by declaration or otherwise; or

         (3) failure to observe or perform in any material respect any other
covenant herein for 90 days after written notice of such failure (specified as
a "Notice of Default"), requiring the Company to remedy the same shall have
been given to the Company and the Guarantor by the Trustee or the holders of at
least 25% in principal amount of the Outstanding Securities; or

         (4) a court or governmental agency having jurisdiction in the premises
shall enter a decree or order for relief in respect of the Company or the
Guarantor in an involuntary case under any applicable federal or state
bankruptcy, insolvency or other similar law now or hereafter in effect, or
appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator
(or similar official) of the Company or the Guarantor or for all or
substantially all of its property or ordering the winding up or liquidation of
its affairs, and such decree or order shall remain unstayed and in effect for a
period of 90 consecutive days; or

         (5) the Company or the Guarantor shall commence a voluntary case under
any applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or consent to the entry of an order for relief in an involuntary case
under any such law, or consent to the appointment or taking possession by a
receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar
official) of the Company or the Guarantor or for all or substantially all of
its property or make any general assignment for the benefit of creditors; or
the Company or the Guarantor shall admit in writing its inability to pay its
debts generally as they become due.

SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Outstanding Securities shall have the right to declare
the principal of and the interest on all the Securities (including any
Additional Interest) and any other amounts payable hereunder to be due and
payable immediately,





                                       24
<PAGE>   31
by a notice in writing to the Company and the Guarantor (and to the Trustee if
given by Holders) and to enforce any and all other rights of Holders of
Securities as creditors with respect to the Securities.  Upon any such
declaration such principal and all accrued interest shall become immediately
due and payable.

         At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter provided in this Article, the Holders of a majority
in principal amount of the Outstanding Securities, by written notice to the
Company and the Guarantor and the Trustee, may rescind and annul such
declaration and its consequences if:

         (1) the Company or the Guarantor has paid or deposited with the
Trustee a sum sufficient to pay,

                    (A) all overdue interest (including any Additional
Interest) on all Securities,

                    (B) the principal of any Securities which have became due
otherwise than by such declaration of acceleration and interest thereon at the
rate borne by the Securities, and

                    (C) all sums paid or advanced by the Trustee hereunder and
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel;

and

         (2) all Events of Default, other than the non-payment of the principal
of Securities which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.  SECTION 503.  Collection of Indebtedness and Suits
for Enforcement by Trustee.

         The Company covenants that if

         (1) default is made in the payment of any interest (including any
Additional Interest) on any Security when such interest becomes due and payable
and such default continues for a period of 90 days (subject to the deferral of
any due and payable interest in the case of an Extension Period), or

         (2) default is made in the payment of the principal of any Security at
the Maturity thereof, the Company will, upon demand of the Trustee, pay to it,
for the benefit of the Holders of such Securities, the whole amount then due
and payable on such Securities for principal and interest (including any
Additional Interest), at the rate borne by the Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the





                                       25
<PAGE>   32
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most

SECTION 504.  Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Company or the
Guarantor, its property or its creditors, the Trustee shall be entitled and
empowered, by intervention in such proceeding or otherwise, to take any and all
actions authorized under the Trust Indenture Act in order to have claims of the
Holders and the Trustee allowed in any such proceeding.  In particular, the
Trustee shall be authorized to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 607.

         No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding.

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.  Application of Money Collected.

Additional Interest), respectively; and

         THIRD: The balance, if any, to the Company.

SECTION 507.  Limitation on Suits.

         No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

         (1) such Holder has previously given written notice to the Trustee of
             a continuing Event of Default;

         (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

         (3) such Holder or Holders have offered to the Trustee such indemnity
as is satisfactory to it against the costs, expenses and liabilities to be
incurred in compliance with such request;

         (4) the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity has failed to institute any such proceeding; and

         (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities; it being understood and
intended that no one or more Holders shall have any right in any manner
whatever by virtue of, or by availing of, any provision of this Indenture to
affect, disturb or prejudice the rights of any other Holders, or to obtain or
to seek to obtain priority or preference over any other Holders or to enforce
any right under this Indenture, except in the manner herein provided and for
the equal and ratable benefit of all the Holders.

SECTION 508.  Unconditional Right of Holders to Receive Principal and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to

(including any Additional Interest) on such Security on the respective Stated
Maturities (subject to the deferral of any due date in the case of an Extension
Period) expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the





                                       27
<PAGE>   34
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

SECTION 509.  Restoration of Rights and Remedies.

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

SECTION 510.  Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.  SECTION 511.  Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 512.  Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee, provided that

         (1) such direction shall not be in conflict with any rule of law or
with this Indenture; and

         (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.





                                       28
<PAGE>   35
SECTION 513.  Waiver of Past Defaults.

         Subject to Section 902, the Holders of not less than a majority in
principal amount of the Outstanding Securities may on behalf of the Holders of
all the Securities waive any past default hereunder and its consequences,
except a default

         (1) in the payment of the principal of or interest (including any
Additional Interest) on any Security (unless such default has been cured and a
sum sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration have been deposited with the Trustee); or

         (2) in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such court
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in
the Trust Indenture Act; provided, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or the Trustee or in any suit for the enforcement of the right to receive the
principal of and interest (including any Additional Interest) on any Security.

SECTION 515.  Acknowledgement.

         The Company and the Guarantor acknowledge that so long as the
Partnership is a Holder, a holder of record of Preferred Securities may to the
fullest extent permitted by law on behalf of the Partnership, when and as
provided in the Limited Partnership Agreement, directly institute a legal
proceeding against the Company under this Indenture or against the Guarantor
under the Guarantee, without first instituting any legal proceeding against the
Property Trustee (as such term is defined in the Limited Partnership Agreement)
or any other party.

relating to the conduct or affecting the liability of or affording protection
to the Trustee shall be subject to the provisions of this Section.

         (d) the Trustee may consult with counsel of its choice at the
Company's and the Guarantor's expense and the advice of such counsel or any

         (i) No provision of this Indenture shall require the 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 grounds to believe that repayments of such
funds or indemnity satisfactory to it against any loss, liability or expense is
not reasonably assured to it.

         (j) The Trustee shall have no duty to monitor the performance of the
Company or the Guarantor or their compliance with the covenants contained

nonfeasance by such parties.

distribution thereof to the holders of the Securities.

SECTION 606.  Money Held in Trust.

under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.

SECTION 607.  Compensation and Reimbursement.

         (1) to pay to the Trustee from time to time such reasonable
compensation as the Company, the Guarantor and the Trustee shall from time to
time agree in writing for all services rendered by it hereunder (which
compensation shall not be limited by any provision of law in regard to the

claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder.

instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; provided that, on
request of the Company, the Guarantor or the successor Trustee, such retiring
Trustee shall, upon payment of its fees, charges and expenses, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder.  Upon request of any such successor Trustee, the Company and

business of the Trustee, shall be the successor of the Trustee 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.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

supplemental indenture in form satisfactory to the Trustee, executed and
delivered to the Trustee by such corporation or other entity, and (ii) the
Company, the





                                       36

Guarantor or such successor corporation or other entity, as the case may be,
shall not, immediately after such merger or consolidation, or such sale or
conveyance, be in default in the performance of any such covenant or condition.
In the event of any Asset Drop-Down after the date of this Indenture, any
subsequent sale or conveyance of assets by a Subsidiary to which assets were
transferred in such Asset Drop-Down (a "Drop-Down Subsidiary") will be deemed
to be a sale or conveyance of assets by the Company or the Guarantor for
purposes of this Section 801.

SECTION 802.  Successor Substituted.

         In case of any such consolidation, merger, sale or conveyance, and
following such an assumption by the successor corporation, such successor
corporation shall succeed to and be substituted for the Company or the
Guarantor, with the same effect as if it had been named herein.  Such successor
corporation may cause to be signed, and may issue either in its own name or in
the name of the Company or the Guarantor prior to such succession any or all of
the Securities issuable hereunder which theretofore shall not have been signed
by the Company and guaranteed by the Guarantor and delivered to the Trustee;
and, upon the order of such successor corporation instead of the Company or the
Guarantor and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the
officers of the Company and the Guarantor  to the Trustee for authentication,
and any Securities which such successor corporation thereafter shall cause to
be signed and delivered to the Trustee for that purpose.  All of the Securities
so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Securities theretofore or thereafter issued in accordance with
the terms of this Indenture as though all of such Securities had been issued at
the date of the execution hereof.

         In case of any such consolidation, merger, sale, lease or conveyance
such changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

         In the event of any such sale or conveyance (other than a conveyance
by way of lease) the Company, the Guarantor or any successor corporation which
shall theretofore have become such in the manner described in this Article
shall be released and discharged from all obligations and covenants under this
Indenture.

SECTION 901.  Supplemental Indentures Without Consent of Holders.

         Without the consent of any Holders, the Company and the Guarantor,

                                       37
<PAGE>   44
         (1) to evidence the succession of another Person to the Company or the
Guarantor and the assumption by any such successor of the covenants of the
Company or the Guarantor herein and in the Securities;

         (2) to add to the covenants of the Company or the Guarantor for the
benefit of the Holders, or to surrender any right or power herein or in the
Securities conferred upon the Company or the Guarantor;

         (3) to cure any ambiguity or to correct any provision herein which may
be defective or inconsistent with any other provision herein;

successor Trustee hereunder; or

         (6) to make any other change that does not adversely affect the rights
of any Holder.

SECTION 902.  Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities, by Act of said Holders
delivered to the Company, the Guarantor and the Trustee, the Company, and the
Guarantor, when authorized by a Board Resolution, and the Trustee may enter
into an indenture or indentures supplemental hereto for the purpose of adding
any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

         (1) change the Stated Maturity of the principal of, or any installment
of interest (including any Additional Interest) on, any Security, or reduce the
principal amount thereof or the rate of interest thereon, or change the place
of payment where, or the coin or currency in which, any Security or interest
thereon is payable, or impair the right to institute suit for the enforcement
of any such payment on or after the Stated Maturity thereof (or, in the case of
redemption, on or after the Redemption Date), or modify the provisions of this
Indenture with respect to the subordination of the Securities in a manner
adverse to the Holders,

         (2) reduce the percentage in principal amount of the Outstanding
Securities, the consent of whose Holders is required for any such supplemental
indenture, or the consent of whose Holders in required for any waiver (of
compliance with certain provisions of this Indenture or certain defaults
hereunder and their consequences) provided for in this Indenture, or





                                       38
<PAGE>   45
         (3) modify any of the provisions of this Section or Section 513,
except to increase any such percentage or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent
of the Holder of each Outstanding Security affected thereby.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

SECTION 903.  Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to

an officer's stating that Certificate precedent to the execution of such
supplemented indenture have been fulfilled and an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by
this Indenture.  The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

SECTION 904.  Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

SECTION 905.  Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

                   Covenants; Representations and Warranties

SECTION 1001.  Payment of Principal and Interest.

         The Company will duly and punctually pay the principal of and interest
on the Securities in accordance with the terms of the Securities and this
Indenture.

SECTION 1002.  Maintenance of Office or Agency.

         The Company will maintain in the United States an office or agency
where Securities may be presented or surrendered for payment, where Securities
may be surrendered for registration of transfer or exchange, where Securities
may be surrendered for conversion and where notices and





                                       39
<PAGE>   46
demands to or upon the Company in respect of the Securities and this Indenture
may be served.  The Company will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency.  If at
any time the Company shall fail to maintain any such required office or agency
or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

         The Company may also from time to time designate one or more other
offices or agencies (in the United States) where the Securities may be
presented or surrendered for any or all such purposes and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to
maintain an office or agency in the United States for such purposes.  The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

SECTION 1003.  Money for Security Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent, it will,
on or at the option of the Company before each due date of the principal of or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Persons entitled thereto a sum sufficient to pay the principal or
interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents, it will, on
or prior to each due date of the principal of or interest on any Securities,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or interest on any
Security and remaining unclaimed for two years after such principal or interest
has become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease.

SECTION 1004.  Reports by the Company.

         The Guarantor shall file with the Trustee and the Commission, and
transmit to Holders, such information, documents and other reports, and such
summaries thereof, as may be required pursuant to the Trust Indenture Act at
the times and in the manner provided pursuant to such Act; provided that any
such information, documents or reports required to be filed with the Commission
pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 shall be
filed with the Trustee within





                                       40
<PAGE>   47
15 days after the same is so required to be filed with the Commission.
Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's or the
Guarantor's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

SECTION 1005.  Negative Pledge and Exceptions Thereto.

         So long as any of the Securities are outstanding, the Company will not
pledge, mortgage or hypothecate, or permit to exist, and will not cause, suffer
or permit any Subsidiary to pledge, mortgage or hypothecate, or permit to
exist, except in favor of the Company or any Subsidiary, any mortgage, pledge
or other lien upon, any Principal Property at any time owned by it, to secure
any indebtedness, without making effective provisions whereby the Securities
shall be equally and ratably secured with any and all such indebtedness and
with any other indebtedness similarly entitled to be equally and ratably
secured; provided, however, that this restriction shall not apply to or prevent
the creation or existence of:

         compliance with the terms of the lease in the case of leasehold

         aggregate amount not in excess of $10,000,000, or the lien of any
         judgment or attachment the execution or enforcement of which has been
         stayed or which has been appealed and secured, if necessary, by the
         filing of an appeal bond;

                    (h)   any mortgage, pledge, lien or encumbrance on any
         property held or used by the Company or a Subsidiary in connection

         acquisition, whether or not assumed by the Company or a Subsidiary,
         provided that every such mortgage, pledge, lien or encumbrance shall
         apply only to the property so acquired and fixed improvements thereon;

                    (k)   any extension, renewal or refunding, in whole or in
         part, of any mortgage, pledge, lien or encumbrance permitted by
         subparagraph (j) above, if limited to the same property or any portion
         thereof subject to, and securing not more than the amount secured by,
         the mortgage, pledge, lien or encumbrance extended, renewed or
         refunded;

         property heretofore or hereafter acquired by any corporation that is
         or becomes a Subsidiary after the date hereof ("Acquired Entity"),

         shall either (A) exist prior to the time the Acquired Entity becomes a
         Subsidiary or (B) be created at the time the Acquired Entity becomes a
         Subsidiary or within one year thereafter to secure all or a portion of

         at any time in connection with the financing of the





                                       42
<PAGE>   49
         acquisition or construction of property to be used in the business of

                    (p)   any lien to secure indebtedness other than Funded
         Debt;

         assumed by the Company or a Subsidiary in connection with the issuance
         of debt securities the interest on which is excludable from gross
         income of the holder of such security pursuant to the Internal Revenue
         Code of 1954, as amended, for the purpose of financing, in whole or in
         part, the acquisition or construction of property to be used by the
         Company or a Subsidiary; or

                    (s)   the pledge or assignment of accounts receivable, or
         the pledge or assignment of conditional sales contracts or chattel
         mortgages and evidences of indebtedness secured thereby, received in

         of goods or merchandise to customers of the Company or such
         Subsidiary.

         In case the Company or any Subsidiary shall propose to pledge,
mortgage or hypothecate any Principal Property at any time owned by it to
secure any indebtedness, other than as permitted by subdivisions (a) to (s),
inclusive, of this Section 1005, the Company (i) will prior thereto give
written notice thereof to the Trustee, and (ii) will, or will cause such
Subsidiary to, prior to or simultaneously with such pledge, mortgage or
hypothecation, enter into a supplemental indenture with the Trustee (or to the
extent legally necessary to another trustee or additional or separate trustee)
that secures all the Securities equally and ratably with such indebtedness.

         Notwithstanding the foregoing provisions of this Section 1005, the
Company or a Subsidiary may issue, assume or guarantee indebtedness secured by
mortgage which would otherwise be subject to the foregoing restrictions in an
aggregate amount which, together with all other indebtedness of the Company or
a Subsidiary secured by a mortgage which (if originally issued, assumed or
guaranteed at such time) would otherwise be subject to the foregoing
restrictions (not including indebtedness permitted to be secured under clauses
(a) through (s) above), does not at the time exceed 10% of the Consolidated Net
Tangible Assets of the Company, as shown on the audited consolidated financial
statements of the Company as of the end of the fiscal year preceding the date
of determination.

SECTION 1006.  Statement as to Compliance; Notice of Certain Events of Default.

         Each of the Company and the Guarantor will, within 120 days after the
close of each fiscal year, commencing with the first fiscal year following the
issuance of Securities under this Indenture, file with the Trustee a
certificate of the principal executive officer, the principal financial officer
or the principal accounting officer of the Company and the Guarantor covering
the period from the date of issuance of such Securities to the end of the
fiscal year in which such Securities were issued, in the case of the first such
certificate, and covering the preceding fiscal year in the case of each
subsequent certificate, and stating whether or not, to the knowledge of the
signer, each of the Company and the Guarantor has complied with all conditions
and covenants on its part contained in this Indenture, and, if the signer has
obtained knowledge of any default by the Guarantor in the performance,
observance or fulfillment of any such condition or covenant, specifying each
such default and the nature thereof.  For the purpose of this Section 1007,
compliance shall be determined without regard to any grace period or
requirement of notice provided pursuant to the terms of this Indenture.

SECTION 1101.  Securities Entitled to Guarantee.

         The Securities shall be entitled to all of the rights and benefits of
the Guarantee provided for by the Guarantor in accordance with the terms
thereof.

                            Redemption of Securities

SECTION 1201.  Optional Redemption.

         (a) At any time on or after December 31, 2001, the Company shall have
the right to redeem the Securities, in whole or in part, from time to time, at
a Redemption Price equal to 100% of the principal amount of Securities to be
redeemed plus accrued but unpaid interest, including any Additional Interest,
if any, to the Redemption Date.

         (b) If, at any time, a Partnership Tax Event or a Partnership
Investment Company Event (each a "Partnership Special Event") shall occur and
be continuing, the Company may, within 90 days following the occurrence of such
Partnership Special Event, elect to redeem the Securities in whole (but not in
part), upon not less than 30 or more than 60 days' notice at the Redemption
Price, provided that, if at the time there is available to the Company or the
Partnership the opportunity to eliminate, within such 90-day period, the
Partnership Special Event by taking some ministerial action, such as filing a
form or making an election, or pursuing some other similar reasonable such
measure that in the sole judgment of the Company has or will cause no adverse
effect on the





                                       44
<PAGE>   51
Partnership, the Trust or the Company, the Company will pursue such measure in
lieu of redemption.

SECTION 1202. Mandatory Redemption.

         If, at any time, a Change of Control shall occur and be continuing,
the Company shall, as promptly as practicable (and in any event within 90 days
following the occurrence of such Change of Control), redeem the Securities in
whole (but not in part), upon not less than 30 or more than 60 days' notice at
the Redemption Price.  As promptly as practicable following a Change of
Control, the Company or the Guarantor shall provide written notice to the
Trustee of such Change of Control.

SECTION 1203.  Applicability of Article.

         Redemption of Securities, at the election of the Company as permitted
by Section 1201, shall be made in accordance with such provision and this
Article.

SECTION 1204.  Authorization for Redemption; Notice to Trustee.

         The election of the Company to redeem Securities pursuant to Section
1201 shall be evidenced by a Board Resolution.  In case of any redemption, the
Company shall, at least 30 days and no more than 60 days prior to the
Redemption Date fixed by the Company, notify the Trustee of such Redemption
Date and of the principal amount of Securities to be redeemed and provide a
copy of the notice of redemption given to Holders of Securities to be redeemed
pursuant to Section 1204.

SECTION 1205.  Selection by Trustee of Securities to Be Redeemed.

         If less then all the Securities are to be redeemed (unless such
redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Trustee, from the Outstanding Securities not previously called for
redemption, by such method (including pro rata or by lot) as the Trustee shall
deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to $25 or any integral multiple thereof) of the
principal amount of the Securities.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to
be redeemed.

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part.  In the case of any such
redemption in part, the unredeemed portion of the principal amount of the

redeemed only in part, to the portion of the principal amount of such
Securities which has been or is to be redeemed.

SECTION 1206.  Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall identify the Securities to be redeemed
and shall state:

         (1) the Redemption Date,

         (2) the Redemption Price,

         (3) that on the Redemption Date the Redemption Price will become due
and payable upon each such security to be redeemed and that interest thereon
will cease to accrue on and after said date, and

         (4) the place or places where such securities are to be surrendered
for payment of the Redemption Price.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1207.  Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

SECTION 1208.  Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such





                                       46
<PAGE>   53
at the close of business on the relevant Record Dates according to their terms
and the provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid, bear
interest from the Redemption Date at the rate borne by the Security.

SECTION 1209.  Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a place of payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company, the Guarantor and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.  The Company may not redeem fewer than all the
Outstanding Securities unless all accrued and unpaid interest (including
Additional Interest) has been paid on such Securities.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                               GUARANTEE TRUSTEE

         SECTION 3.1      Powers and Duties of the Investment Guarantee Trustee

         (a)     This Investment Guarantee shall be held by the Investment
Guarantee Trustee for the benefit of the Holders of the Affiliate Debenture,
and the Investment Guarantee Trustee shall not transfer this Investment
Guarantee to any Person except a Holder of the Affiliate Debenture exercising
his or her rights pursuant to Section 5.4(b) or to a Successor Investment
Guarantee Trustee on acceptance by such Successor Investment Guarantee Trustee
of its appointment to act as Successor Investment Guarantee Trustee.  The
right, title and interest of the Investment Guarantee Trustee shall
automatically vest in any Successor Investment Guarantee Trustee, and such
vesting and cessation of title shall be effective whether or not conveyancing
documents have been executed and delivered pursuant to the appointment of such
Successor Investment Guarantee Trustee.

         (b)     If an Event of Default actually known to a Responsible officer
of the Investment Guarantee Trustee has occurred and is continuing, the
Investment Guarantee Trustee shall enforce this Investment Guarantee for the
benefit of the Holders of the Affiliate Debenture.

         (c)     The Investment Guarantee Trustee, before the occurrence of any
Event of Default and after the curing of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Investment Guarantee, and no implied covenants shall be read into
this Investment Guarantee against the Investment Guarantee Trustee.  In case an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 2.6) and is actually known to a Responsible Officer of the Investment
Guarantee Trustee, the Investment Guarantee Trustee shall exercise such of the
rights and powers vested in it by this Investment Guarantee, and use the same
degree of care and skill in its exercise thereof, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

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

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

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

                          (B)     in the absence of bad faith on the part of
                 the Investment Guarantee Trustee, the Investment Guarantee
                 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
                 Investment Guarantee Trustee and conforming to the
                 requirements of this Investment Guarantee; but in the case of
                 any such certificates or opinions that by any provision hereof
                 are specifically required to be furnished to the Investment
                 Guarantee Trustee, the Investment Guarantee Trustee shall be
                 under a duty to examine the same to determine whether or not
                 they conform to the requirements of this Investment Guarantee;

                 (ii)     the Investment Guarantee Trustee shall not be liable
         for any error of judgment made in good faith by a Responsible officer
         of the Investment Guarantee Trustee, unless it shall be proved that
         the

         pertinent facts upon which such judgment was made;

                 (iii)    the Investment Guarantee 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 the Affiliate
         Debenture relating to the time, method and place of conducting any
         proceeding for any remedy available to the Investment Guarantee
         Trustee, or exercising any trust or power conferred upon the
         Investment Guarantee Trustee under this Investment Guarantee; and

                 (iv)     no provision of this Investment Guarantee shall
         require the Investment Guarantee Trustee to expend or risk its own
         funds or otherwise incur personal financial liability in the
         performance of any of its duties or in the exercise of any of its
         rights or powers, if the Investment Guarantee Trustee shall have
         reasonable grounds for believing that the repayment of such funds or
         liability is not reasonably assured to it under the terms of this
         Investment Guarantee or indemnity, reasonably satisfactory to the
         Investment Guarantee Trustee, against such risk or liability is not
         reasonably assured to it.

         SECTION 3.2      Certain Rights of Investment Guarantee Trustee

         (a)     Subject to the provisions of Section 3.1:

                 (i)      The Investment Guarantee Trustee may conclusively
         rely, and shall be fully protected in acting or refraining from acting
         upon, any resolution, certificate, statement, instrument, opinion,
         report, notice, request, direction, consent, order, bond, debenture,
         note, other evidence of indebtedness or other paper or document
         believed by it to be genuine and to have been signed, sent or
         presented by the proper party or parties.

                 (ii)     Any direction or act of the Guarantor contemplated by
         this Investment Guarantee shall be sufficiently evidenced by an
         Officers' Certificate.

                 (iii)    Whenever, in the administration of this Investment
         Guarantee, the Investment Guarantee Trustee shall deem it desirable
         that a matter be proved or established before taking, suffering or
         omitting any action hereunder, the Investment Guarantee Trustee
         (unless other evidence is herein specifically prescribed) may, in the
         absence of bad faith on its part, request and conclusively rely upon
         an Officers' Certificate which, upon receipt of such request, shall be
         promptly delivered by the Guarantor.

                 (iv)     The Investment Guarantee Trustee shall have no duty
         to see to any recording, filing or registration of any instrument (or
         any rerecording, refiling or reregistration thereof).

                 (v)      The Investment Guarantee Trustee may, at the expense
         of the Guarantor, consult with counsel of its selection, and the
         advice or opinion of such counsel with respect to legal matters shall
         be full and complete authorization and protection in respect of any
         action taken, suffered or omitted by it hereunder in good faith and in
         accordance with such advice or opinion.  Such counsel may be counsel
         to the Guarantor or any of its Affiliates and may include any of its
         employees.  The Investment Guarantee Trustee shall have the right at
         any time to seek instructions concerning the administration of this
         Investment Guarantee from any court of competent jurisdiction.

                 (vi)     The Investment Guarantee Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by
         this Investment Guarantee at the request or direction of any Holder,
         unless such Holder shall have provided to the Investment Guarantee
         Trustee such security and indemnity, reasonably satisfactory to the
         Investment Guarantee Trustee, against the costs, expenses (including
         attorneys' fees and expenses and the expenses of the Investment
         Guarantee Trustee's agents, nominees or custodians) and liabilities
         that might be incurred by it in complying with such request or
         direction, including such reasonable advances as may be requested by
         the Investment Guarantee Trustee; provided





                                       6
<PAGE>   8
         that, nothing contained in this Section 3.2(a)(vi) shall be taken to
         relieve the Investment Guarantee Trustee, upon the occurrence of an
         Event of Default, of its obligation to exercise the rights and powers
         vested in it by this Investment Guarantee.

                 (vii)    The Investment Guarantee Trustee shall not be bound
         to make any investigation into the facts or matters stated in any
         resolution, certificate, statement, instrument, opinion, report,
         notice, request, direction, consent, order, bond, debenture, note,
         other evidence of indebtedness or other paper or document, but the
         Investment Guarantee Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit.

                 (viii)   The Investment Guarantee Trustee may execute any of
         the trusts or powers hereunder or perform any duties hereunder either
         directly or by or through agents, nominees, custodians or attorneys,
         and the Investment Guarantee Trustee shall not be responsible for any
         misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder.

                 (ix)     Any action taken by the Investment Guarantee Trustee
         or its agents hereunder shall bind the Holders of the Affiliate
         Debenture, and the signature of the Investment Guarantee Trustee or
         its agents alone shall be sufficient and effective to perform any such
         action.  No third party shall be required to inquire as to the
         authority of the Investment Guarantee Trustee to so act or as to its
         compliance with any of the terms and provisions of this Investment
         Guarantee, both of which shall be conclusively evidenced by the
         Investment Guarantee Trustee or its agent taking such action.

                 (x)      Whenever in the administration of this Investment
         Guarantee the Investment Guarantee Trustee shall deem it desirable to
         receive instructions with respect to enforcing any remedy or right or
         taking any other action hereunder, the Investment Guarantee Trustee
         (i) may request instructions from the Holders of a Majority in
         liquidation amount of the Affiliate Debenture, (ii) may refrain from
         enforcing such remedy or right or taking such other action until such
         instructions are received, and (iii) shall be protected in
         conclusively relying on or acting in accordance with such
         instructions.

                 (xi)     The Investment Guarantee Trustee shall not be liable
         for any action taken, suffered, or omitted to be taken by it in good
         faith and reasonably believed by it to be authorized or within the
         discretion or rights or powers conferred upon it by this Investment
         Guarantee.

         (b)     No provision of this Investment Guarantee shall be deemed to
impose any duty or obligation on the Investment Guarantee Trustee to perform
any act or acts or exercise any right, power, duty or obligation conferred or
imposed on it in any jurisdiction in which it shall be illegal, or in which the
Investment Guarantee Trustee shall be unqualified or incompetent in accordance
with applicable law, to perform any such act or acts or to exercise any such
right, power, duty or obligation.  No permissive power or authority available
to the Investment Guarantee Trustee shall be construed to be a duty.

         SECTION 3.3      Not Responsible for Recitals or Issuance of
Investment Guarantee

         The recitals contained in this Investment Guarantee shall be taken as
the statements of the Guarantor, and the Investment Guarantee Trustee does not
assume any responsibility for their correctness.  The Investment Guarantee
Trustee makes no representation as to the validity or sufficiency of this
Investment Guarantee.

<PAGE>   9
                 (i)      not be an Affiliate of the Guarantor; and

                 (ii)     be a corporation organized and doing business under
         the laws of the United States of America or any State or Territory
         thereof or of the District of Columbia, or a corporation or Person

         and subject to supervision or examination by Federal, State,
         Territorial or District of Columbia authority.  If such corporation
         publishes reports of condition at least annually, pursuant to law or
         to the requirements of the supervising or examining authority referred
         to above, then, for the purposes of this Section 4.1(a)(ii), the
         combined capital and surplus of such corporation shall be deemed to be
         its combined capital and surplus as set forth in its most recent
         report of condition so published.

         (b)     If at any time the Investment Guarantee Trustee shall cease to
be eligible to so act under Section 4.1(a), the Investment Guarantee Trustee
shall immediately resign in the manner and with the effect set out in Section
4.2(c).

"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Investment Guarantee Trustee and Guarantor shall in all
respects comply with the provisions of Section 310(b) of the Trust Indenture
Act.

         SECTION 4.2      Appointment, Removal and Resignation of Investment
Guarantee Trustee

         (a)     Subject to Section 4.2(b), the Investment Guarantee Trustee
may be appointed or removed without cause at any time by the Guarantor except
during an Event of Default.

         (b)     The Investment Guarantee Trustee shall not be removed in
accordance with Section 4.2(a) until a Successor Investment Guarantee Trustee
has been appointed and has accepted such appointment by written instrument
executed by such Successor Investment Guarantee Trustee and delivered to the
Guarantor.

         (c)     The Investment Guarantee Trustee appointed to office shall
hold office until a Successor Investment Guarantee Trustee shall have been
appointed or until its removal or resignation.  The Investment Guarantee
Trustee may resign from office (without need for prior or subsequent
accounting) by an instrument in writing executed by the Investment Guarantee
Trustee and delivered to the Guarantor, which resignation shall not take effect
until a Successor Investment Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Investment Guarantee Trustee and delivered to the Guarantor and the resigning
Investment Guarantee Trustee.

         (d)     If no Successor Investment Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 60
days after delivery of an instrument of removal or resignation, the Investment
Guarantee Trustee resigning or being removed may petition any court of
competent jurisdiction for appointment of a Successor Investment Guarantee
Trustee.  Such court may thereupon, after prescribing such notice, if any, as
it may deem proper, appoint a Successor Investment Guarantee Trustee.

         (e)     No Investment Guarantee Trustee shall be liable for the acts
or omissions to act of any Successor Investment Guarantee Trustee.

         (f)     Upon termination of this Investment Guarantee or removal or
resignation of the Investment Guarantee Trustee pursuant to this Section 4.2
and before the appointment of any Successor Investment Guarantee Trustee, the
Guarantor shall pay to the Investment Guarantee Trustee all amounts to which it
is entitled to the date of such termination, removal or resignation.

                                   GUARANTEE

         SECTION 5.1      Guarantee

         The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Issuer), if, as and when due, regardless of any defense, right of
setoff or counterclaim that the Issuer may have or assert.  The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of
the required amounts by the Guarantor to the Holders or by causing the Issuer
to pay such amounts to the Holders.

         SECTION 5.2      Waiver of Notice and Demand

         The Guarantor hereby waives notice of acceptance of this Investment
Guarantee and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the Issuer
or any other Person before proceeding against the Guarantor, protest, notice of
nonpayment, notice of dishonor, notice of redemption and all other notices and
demands.

         SECTION 5.3      Obligations Not Affected

         The obligations, covenants, agreements and duties of the Guarantor
under this Investment Guarantee shall in no way be affected or impaired by
reason of the happening from time to time of any of the following:

         (a)     the release or waiver, by operation of law or otherwise, of
the performance or observance by the Issuer of any express or implied
agreement, covenant, term or condition relating to the Affiliate Debenture to
be performed or observed by the Issuer;

         (b)     the extension of time for the payment by the Issuer of all or
any portion of the interest, principal or premiums, if any, or any other sums
payable under the terms of the Affiliate Debenture or the extension of time for
the performance of any other obligation under, arising out of, or in connection
with, the Affiliate Debenture (other than an extension of time for payment of
interest during an Extension Period (as defined in the Affiliate Indenture));

         (c)     any failure, omission, delay or lack of diligence on the part
of the Holders to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Holders pursuant to the terms of the Affiliate
Debenture, or any action on the part of the Issuer granting indulgence or
extension of any kind;

         (d)     the voluntary or involuntary liquidation, dissolution, sale of
any collateral, receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment
of debt of, or other similar proceedings affecting, the Issuer or any of the
assets of the Issuer;

         (e)     any invalidity of, or defect or deficiency in, the Affiliate
Debenture;

         (f)     the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or

         (g)     any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor, it being
the intent of this Section 5.3 that the obligations of the Guarantor hereunder
shall be absolute and unconditional under any and all circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.





                                       9
<PAGE>   11
         SECTION 5.4      Rights of Holders

         (a)     The Holders of a Majority in liquidation amount of the
Affiliate Debenture have the right to direct the time, method and place of
conducting of any proceeding for any remedy available to the Investment
Guarantee Trustee in respect of this Investment Guarantee or exercising any
trust or power conferred upon the Investment Guarantee Trustee under this
Investment Guarantee.

         (b)     If the Investment Guarantee Trustee fails to enforce its
rights under the Investment Guarantee after a Holder of the Affiliate Debenture
has made a written request, such Holder of the Affiliate Debenture may
institute a legal proceeding directly against the Guarantor to enforce the
Investment Guarantee Trustee's rights under this Investment Guarantee, without
first instituting a legal proceeding against the Issuer, the Investment
Guarantee Trustee or any other Person.  Notwithstanding the foregoing, if the
Guarantor has failed to make a Guarantee Payment, a Holder of the Affiliate
Debenture may directly institute a proceeding in such Holder's own name against
the Guarantor for enforcement of the Investment Guarantee for such payment.
The Guarantor waives any right or remedy to require that any action be brought
first against the Issuer or any other person or entity before proceeding
directly against the Guarantor.

         SECTION 5.5      Guarantee of Payment

         This Investment Guarantee creates a guarantee of payment and not of
collection.

         SECTION 5.6      Subrogation

         The Guarantor shall be subrogated to all (if any) rights of the
Holders of Affiliate Debenture against the Issuer in respect of any amounts
paid to such Holders by the Guarantor under this Investment Guarantee;
provided, however, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any right
that it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Investment
Guarantee, if, at the time of any such payment, any amounts are due and unpaid
under this Investment Guarantee.  If any amount shall be paid to the Guarantor
in violation of the preceding sentence, the Guarantor agrees to hold such
amount in trust for the Holders and to pay over such amount to the Holders.

         SECTION 5.7      Independent Obligations

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Affiliate
Debenture, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Investment
Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

                                   ARTICLE VI
                                 SUBORDINATION

         SECTION 6.1      Ranking

         This Investment Guarantee will constitute an unsecured obligation of
the Guarantor and will rank (i) subordinate and junior in right of payment to
all other liabilities of the Guarantor, including, without limitation, the
fees, charges, expenses and indemnities due to the Property Trustee or the
Delaware Trustee in respect of the Declaration of Trust, the Trust Preferred
Securities Guarantee and the Affiliate Debenture Guarantee Agreement, (ii) pari
passu with the most senior preferred or preference stock now or hereafter
issued by the Guarantor and with any guarantee now or hereafter entered into by
the Guarantor in respect of any preferred security of any Affiliate of the
Guarantor, and (iii) senior to the Guarantor's common stock.

                                  TERMINATION

         SECTION 7.1      Termination

         This Investment Guarantee shall terminate upon the repayment in full
(whether at maturity, upon redemption or otherwise) of all of the principal of,
interest on (including all accrued and unpaid interest thereon) and any other
amounts payable in respect of the Affiliate Debenture.  Notwithstanding the
foregoing, this Investment Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder of the Affiliate
Debenture must restore payment of any sums paid under the Affiliate Debenture
or under this Investment Guarantee.

                                  ARTICLE VIII

accountable in damages or otherwise to the Guarantor or any Covered Person for

or omitted by such Indemnified Person in good faith in accordance with this
Investment Guarantee and in a manner that such Indemnified Person reasonably
believed to be within the scope of the authority conferred on such Indemnified
Person by this Investment Guarantee or by law, except that an Indemnified
Person shall be liable for any such loss, damage or claim incurred by reason of
such Indemnified Person's gross negligence or willful misconduct with respect
to such acts or omissions.

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

         SECTION 8.2      Indemnification

         The Guarantor agrees to indemnify each Indemnified Person for, and to
hold each Indemnified Person harmless against, any and all loss, liability,
damage, claim or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.  The obligation to
indemnify as set forth in this Section 8.2 shall survive the termination of
this Investment Guarantee or the resignation or removal of the Investment
Guarantee Trustee.

                                   ARTICLE IX

         SECTION 9.2      Amendments

         Except with respect to any changes that do not adversely affect the
rights of Holders (in which case no consent of Holders will be required), this
Investment Guarantee may only be amended with the prior approval of the Holders
of at least a Majority in liquidation amount of the Affiliate Debenture.

         SECTION 9.3      Merger of the Guarantor

         The Guarantor covenants that it will not merge or consolidate with any
other corporation or other entity or sell or convey all or substantially all of
its assets to any person (other than such a sale or conveyance to a Subsidiary
or any successor thereto (such a sale or conveyance being called an "Asset
Drop-Down")), unless (i) either the Guarantor shall be the continuing
corporation or the successor corporation or other entity or the person which
acquires by sale or conveyance substantially all the assets of the Guarantor
shall expressly assume the obligations of the Guarantor hereunder, according to
their tenor, and the due and punctual performance and observance of all of the
covenants hereof to be performed or observed by the Guarantor, by instrument in
form satisfactory to the Investment Guarantee Trustee, executed and delivered

(ii) the Guarantor or such successor corporation or other entity, as the case
may be, shall not, immediately after such merger or consolidation, or such sale
or conveyance, be in default in the performance of any such covenant or
condition.  In the event of any Asset Drop-Down after the date hereof, any
subsequent sale or conveyance of assets by a Subsidiary to which assets were
transferred in such Asset Drop-Down will be deemed to be a sale or conveyance
of assets by the Company for purposes of this provision.

                               GUARANTEE TRUSTEE

         SECTION 3.1      Powers and Duties of the Investment Guarantee Trustee

         (a)     This Investment Guarantee shall be held by the Investment
Guarantee Trustee for the benefit of the Holders of the Affiliate Debenture,
and the Investment Guarantee Trustee shall not transfer this Investment
Guarantee to any Person except a Holder of the Affiliate Debenture exercising
his or her rights pursuant to Section 5.4(b) or to a Successor Investment
Guarantee Trustee on acceptance by such Successor Investment Guarantee Trustee
of its appointment to act as Successor Investment Guarantee Trustee.  The
right, title and interest of the Investment Guarantee Trustee shall
automatically vest in any Successor Investment Guarantee Trustee, and such
vesting and cessation of title shall be effective whether or not conveyancing
documents have been executed and delivered pursuant to the appointment of such
Successor Investment Guarantee Trustee.

         (b)     If an Event of Default actually known to a Responsible officer
of the Investment Guarantee Trustee has occurred and is continuing, the
Investment Guarantee Trustee shall enforce this Investment Guarantee for the
benefit of the Holders of the Affiliate Debenture.

         (c)     The Investment Guarantee Trustee, before the occurrence of any
Event of Default and after the curing of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Investment Guarantee, and no implied covenants shall be read into
this Investment Guarantee against the Investment Guarantee Trustee.  In case an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 2.6) and is actually known to a Responsible Officer of the Investment
Guarantee Trustee, the Investment Guarantee Trustee shall exercise such of the
rights and powers vested in it by this Investment Guarantee, and use the same
degree of care and skill in its exercise thereof, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

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

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

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

                          (B)     in the absence of bad faith on the part of
                 the Investment Guarantee Trustee, the Investment Guarantee
                 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
                 Investment Guarantee Trustee and conforming to the
                 requirements of this Investment Guarantee; but in the case of
                 any such certificates or opinions that by any provision hereof
                 are specifically required to be furnished to the Investment
                 Guarantee Trustee, the Investment Guarantee Trustee shall be
                 under a duty to examine the same to determine whether or not
                 they conform to the requirements of this Investment Guarantee;

                 (ii)     the Investment Guarantee Trustee shall not be liable
         for any error of judgment made in good faith by a Responsible officer
         of the Investment Guarantee Trustee, unless it shall be proved that
         the





                                       5

         Investment Guarantee Trustee was negligent in ascertaining the
         pertinent facts upon which such judgment was made;

                 (iii)    the Investment Guarantee 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 the Affiliate
         Debenture relating to the time, method and place of conducting any
         proceeding for any remedy available to the Investment Guarantee
         Trustee, or exercising any trust or power conferred upon the
         Investment Guarantee Trustee under this Investment Guarantee; and

                 (iv)     no provision of this Investment Guarantee shall
         require the Investment Guarantee Trustee to expend or risk its own
         funds or otherwise incur personal financial liability in the
         performance of any of its duties or in the exercise of any of its
         rights or powers, if the Investment Guarantee Trustee shall have
         reasonable grounds for believing that the repayment of such funds or
         liability is not reasonably assured to it under the terms of this
         Investment Guarantee or indemnity, reasonably satisfactory to the
         Investment Guarantee Trustee, against such risk or liability is not
         reasonably assured to it.

         (unless other evidence is herein specifically prescribed) may, in the
         absence of bad faith on its part, request and conclusively rely upon

                 (vi)     The Investment Guarantee Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by
         this Investment Guarantee at the request or direction of any Holder,
         unless such Holder shall have provided to the Investment Guarantee
         Trustee such security and indemnity, reasonably satisfactory to the
         Investment Guarantee Trustee, against the costs, expenses (including
         attorneys' fees and expenses and the expenses of the Investment
         Guarantee Trustee's agents, nominees or custodians) and liabilities
         that might be incurred by it in complying with such request or
         direction, including such reasonable advances as may be requested by
         the Investment Guarantee Trustee; provided





                                       6
<PAGE>   8
         that, nothing contained in this Section 3.2(a)(vi) shall be taken to
         relieve the Investment Guarantee Trustee, upon the occurrence of an
         Event of Default, of its obligation to exercise the rights and powers
         vested in it by this Investment Guarantee.

                 (vii)    The Investment Guarantee Trustee shall not be bound
         to make any investigation into the facts or matters stated in any
         resolution, certificate, statement, instrument, opinion, report,
         notice, request, direction, consent, order, bond, debenture, note,
         other evidence of indebtedness or other paper or document, but the
         Investment Guarantee Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit.

                 (viii)   The Investment Guarantee Trustee may execute any of
         the trusts or powers hereunder or perform any duties hereunder either
         directly or by or through agents, nominees, custodians or attorneys,
         and the Investment Guarantee Trustee shall not be responsible for any
         misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder.

                 (ix)     Any action taken by the Investment Guarantee Trustee
         or its agents hereunder shall bind the Holders of the Affiliate
         Debenture, and the signature of the Investment Guarantee Trustee or
         its agents alone shall be sufficient and effective to perform any such
         action.  No third party shall be required to inquire as to the
         authority of the Investment Guarantee Trustee to so act or as to its
         compliance with any of the terms and provisions of this Investment
         Guarantee, both of which shall be conclusively evidenced by the
         Investment Guarantee Trustee or its agent taking such action.

                 (x)      Whenever in the administration of this Investment
         Guarantee the Investment Guarantee Trustee shall deem it desirable to
         receive instructions with respect to enforcing any remedy or right or
         taking any other action hereunder, the Investment Guarantee Trustee
         (i) may request instructions from the Holders of a Majority in
         liquidation amount of the Affiliate Debenture, (ii) may refrain from
         enforcing such remedy or right or taking such other action until such
         instructions are received, and (iii) shall be protected in
         conclusively relying on or acting in accordance with such
         instructions.

                 (xi)     The Investment Guarantee Trustee shall not be liable
         for any action taken, suffered, or omitted to be taken by it in good
         faith and reasonably believed by it to be authorized or within the
         discretion or rights or powers conferred upon it by this Investment
         Guarantee.

         (b)     No provision of this Investment Guarantee shall be deemed to
impose any duty or obligation on the Investment Guarantee Trustee to perform
any act or acts or exercise any right, power, duty or obligation conferred or
imposed on it in any jurisdiction in which it shall be illegal, or in which the
Investment Guarantee Trustee shall be unqualified or incompetent in accordance
with applicable law, to perform any such act or acts or to exercise any such
right, power, duty or obligation.  No permissive power or authority available
to the Investment Guarantee Trustee shall be construed to be a duty.

         SECTION 3.3      Not Responsible for Recitals or Issuance of
Investment Guarantee

         The recitals contained in this Investment Guarantee shall be taken as
the statements of the Guarantor, and the Investment Guarantee Trustee does not
assume any responsibility for their correctness.  The Investment Guarantee
Trustee makes no representation as to the validity or sufficiency of this
Investment Guarantee.

<PAGE>   9
                 (i)      not be an Affiliate of the Guarantor; and

                 (ii)     be a corporation organized and doing business under
         the laws of the United States of America or any State or Territory
         thereof or of the District of Columbia, or a corporation or Person

         and subject to supervision or examination by Federal, State,
         Territorial or District of Columbia authority.  If such corporation
         publishes reports of condition at least annually, pursuant to law or
         to the requirements of the supervising or examining authority referred
         to above, then, for the purposes of this Section 4.1(a)(ii), the
         combined capital and surplus of such corporation shall be deemed to be
         its combined capital and surplus as set forth in its most recent
         report of condition so published.

         (b)     If at any time the Investment Guarantee Trustee shall cease to
be eligible to so act under Section 4.1(a), the Investment Guarantee Trustee
shall immediately resign in the manner and with the effect set out in Section
4.2(c).

         (c)     If the Investment Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Investment Guarantee Trustee and Guarantor shall in all
respects comply with the provisions of Section 310(b) of the Trust Indenture
Act.

         SECTION 4.2      Appointment, Removal and Resignation of Investment
Guarantee Trustee

         (a)     Subject to Section 4.2(b), the Investment Guarantee Trustee
may be appointed or removed without cause at any time by the Guarantor except
during an Event of Default.

         (b)     The Investment Guarantee Trustee shall not be removed in
accordance with Section 4.2(a) until a Successor Investment Guarantee Trustee
has been appointed and has accepted such appointment by written instrument
executed by such Successor Investment Guarantee Trustee and delivered to the
Guarantor.

         (c)     The Investment Guarantee Trustee appointed to office shall
hold office until a Successor Investment Guarantee Trustee shall have been
appointed or until its removal or resignation.  The Investment Guarantee
Trustee may resign from office (without need for prior or subsequent
accounting) by an instrument in writing executed by the Investment Guarantee
Trustee and delivered to the Guarantor, which resignation shall not take effect
until a Successor Investment Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Investment Guarantee Trustee and delivered to the Guarantor and the resigning
Investment Guarantee Trustee.

         (d)     If no Successor Investment Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 60
days after delivery of an instrument of removal or resignation, the Investment
Guarantee Trustee resigning or being removed may petition any court of
competent jurisdiction for appointment of a Successor Investment Guarantee
Trustee.  Such court may thereupon, after prescribing such notice, if any, as
it may deem proper, appoint a Successor Investment Guarantee Trustee.

         (e)     No Investment Guarantee Trustee shall be liable for the acts
or omissions to act of any Successor Investment Guarantee Trustee.

         (f)     Upon termination of this Investment Guarantee or removal or
resignation of the Investment Guarantee Trustee pursuant to this Section 4.2
and before the appointment of any Successor Investment Guarantee Trustee, the
Guarantor shall pay to the Investment Guarantee Trustee all amounts to which it
is entitled to the date of such termination, removal or resignation.

                                   GUARANTEE

         SECTION 5.1      Guarantee

         The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Issuer), if, as and when due, regardless of any defense, right of
setoff or counterclaim that the Issuer may have or assert.  The Guarantor's
obligation to make a Guarantee Payment may be satisfied by direct payment of
the required amounts by the Guarantor to the Holders or by causing the Issuer
to pay such amounts to the Holders.

         SECTION 5.2      Waiver of Notice and Demand

         The Guarantor hereby waives notice of acceptance of this Investment
Guarantee and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the Issuer
or any other Person before proceeding against the Guarantor, protest, notice of
nonpayment, notice of dishonor, notice of redemption and all other notices and
demands.

         SECTION 5.3      Obligations Not Affected

         The obligations, covenants, agreements and duties of the Guarantor
under this Investment Guarantee shall in no way be affected or impaired by
reason of the happening from time to time of any of the following:

         (a)     the release or waiver, by operation of law or otherwise, of
the performance or observance by the Issuer of any express or implied
agreement, covenant, term or condition relating to the Affiliate Debenture to
be performed or observed by the Issuer;

         (b)     the extension of time for the payment by the Issuer of all or
any portion of the interest, principal or premiums, if any, or any other sums
payable under the terms of the Affiliate Debenture or the extension of time for
the performance of any other obligation under, arising out of, or in connection
with, the Affiliate Debenture (other than an extension of time for payment of
interest during an Extension Period (as defined in the Affiliate Indenture));

         (c)     any failure, omission, delay or lack of diligence on the part
of the Holders to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Holders pursuant to the terms of the Affiliate
Debenture, or any action on the part of the Issuer granting indulgence or
extension of any kind;

         (d)     the voluntary or involuntary liquidation, dissolution, sale of
any collateral, receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment
of debt of, or other similar proceedings affecting, the Issuer or any of the
assets of the Issuer;

         (e)     any invalidity of, or defect or deficiency in, the Affiliate
Debenture;

         (f)     the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or

         (g)     any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor, it being
the intent of this Section 5.3 that the obligations of the Guarantor hereunder
shall be absolute and unconditional under any and all circumstances.

         There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.





                                       9
<PAGE>   11
         SECTION 5.4      Rights of Holders

         (a)     The Holders of a Majority in liquidation amount of the
Affiliate Debenture have the right to direct the time, method and place of
conducting of any proceeding for any remedy available to the Investment
Guarantee Trustee in respect of this Investment Guarantee or exercising any
trust or power conferred upon the Investment Guarantee Trustee under this
Investment Guarantee.

         (b)     If the Investment Guarantee Trustee fails to enforce its
rights under the Investment Guarantee after a Holder of the Affiliate Debenture
has made a written request, such Holder of the Affiliate Debenture may
institute a legal proceeding directly against the Guarantor to enforce the
Investment Guarantee Trustee's rights under this Investment Guarantee, without
first instituting a legal proceeding against the Issuer, the Investment
Guarantee Trustee or any other Person.  Notwithstanding the foregoing, if the
Guarantor has failed to make a Guarantee Payment, a Holder of the Affiliate
Debenture may directly institute a proceeding in such Holder's own name against
the Guarantor for enforcement of the Investment Guarantee for such payment.
The Guarantor waives any right or remedy to require that any action be brought
first against the Issuer or any other person or entity before proceeding
directly against the Guarantor.

         SECTION 5.5      Guarantee of Payment

         This Investment Guarantee creates a guarantee of payment and not of
collection.

         SECTION 5.6      Subrogation

         The Guarantor shall be subrogated to all (if any) rights of the
Holders of Affiliate Debenture against the Issuer in respect of any amounts
paid to such Holders by the Guarantor under this Investment Guarantee;
provided, however, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any right
that it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Investment
Guarantee, if, at the time of any such payment, any amounts are due and unpaid
under this Investment Guarantee.  If any amount shall be paid to the Guarantor
in violation of the preceding sentence, the Guarantor agrees to hold such
amount in trust for the Holders and to pay over such amount to the Holders.

         SECTION 5.7      Independent Obligations

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Affiliate
Debenture, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Investment
Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

                                   ARTICLE VI
                                 SUBORDINATION

         SECTION 6.1      Ranking

         This Investment Guarantee will constitute an unsecured obligation of
the Guarantor and will rank (i) subordinate and junior in right of payment to
all other liabilities of the Guarantor, including, without limitation, the
fees, charges, expenses and indemnities due to the Property Trustee or the
Delaware Trustee in respect of the Declaration of Trust, the Trust Preferred
Securities Guarantee and the Affiliate Debenture Guarantee Agreement, (ii) pari
passu with the most senior preferred or preference stock now or hereafter
issued by the Guarantor and with any guarantee now or hereafter entered into by
the Guarantor in respect of any preferred security of any Affiliate of the
Guarantor, and (iii) senior to the Guarantor's common stock.

                                  TERMINATION

         SECTION 7.1      Termination

         This Investment Guarantee shall terminate upon the repayment in full
(whether at maturity, upon redemption or otherwise) of all of the principal of,
interest on (including all accrued and unpaid interest thereon) and any other
amounts payable in respect of the Affiliate Debenture.  Notwithstanding the
foregoing, this Investment Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder of the Affiliate
Debenture must restore payment of any sums paid under the Affiliate Debenture
or under this Investment Guarantee.

                                  ARTICLE VIII

         SECTION 8.1      Exculpation

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

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

         SECTION 8.2      Indemnification

         The Guarantor agrees to indemnify each Indemnified Person for, and to
hold each Indemnified Person harmless against, any and all loss, liability,
damage, claim or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.  The obligation to
indemnify as set forth in this Section 8.2 shall survive the termination of
this Investment Guarantee or the resignation or removal of the Investment
Guarantee Trustee.

                                   ARTICLE IX
                                 MISCELLANEOUS

         SECTION 9.1      Successors and Assigns

                                       11
<PAGE>   13
         SECTION 9.2      Amendments

         Except with respect to any changes that do not adversely affect the
rights of Holders (in which case no consent of Holders will be required), this
Investment Guarantee may only be amended with the prior approval of the Holders
of at least a Majority in liquidation amount of the Affiliate Debenture.

         SECTION 9.3      Merger of the Guarantor

         The Guarantor covenants that it will not merge or consolidate with any
other corporation or other entity or sell or convey all or substantially all of
its assets to any person (other than such a sale or conveyance to a Subsidiary
or any successor thereto (such a sale or conveyance being called an "Asset
Drop-Down")), unless (i) either the Guarantor shall be the continuing
corporation or the successor corporation or other entity or the person which
acquires by sale or conveyance substantially all the assets of the Guarantor
shall expressly assume the obligations of the Guarantor hereunder, according to
their tenor, and the due and punctual performance and observance of all of the
covenants hereof to be performed or observed by the Guarantor, by instrument in
form satisfactory to the Investment Guarantee Trustee, executed and delivered
to the Investment Guarantee Trustee by such corporation or other entity, and
(ii) the Guarantor or such successor corporation or other entity, as the case
may be, shall not, immediately after such merger or consolidation, or such sale
or conveyance, be in default in the performance of any such covenant or
condition.  In the event of any Asset Drop-Down after the date hereof, any
subsequent sale or conveyance of assets by a Subsidiary to which assets were
transferred in such Asset Drop-Down will be deemed to be a sale or conveyance
of assets by the Company for purposes of this provision.
