or an electronic transmission, provided that such electronic transmission is
transmitted through the facilities of a Depositary) by such Holders in person or
by an agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered (either physically or by means of a facsimile or an electronic
transmission, provided that such electronic transmission is transmitted through
the facilities of a Depositary) to the Trustee and, where it is hereby expressly
required, to the Partnership. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the

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.

other action 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


                                      -9-
<PAGE>
Partnership in reliance thereon, regardless of whether notation of such action
is made upon such Security.

      Without limiting the foregoing, a Holder entitled hereunder to give or
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any different part of such principal amount.

      The Partnership may set any day as the record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to give
or take any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given or taken by
Holders of Securities of such series, but the Partnership shall have no
obligation to do so. With regard to any record date set pursuant to this
paragraph, the Holders of Outstanding Securities of the relevant series on such
record date (or their duly appointed agents), and only such Persons, shall be
entitled to give or take the relevant action, regardless of whether such Holders
remain Holders after such record date.

SECTION 105. Notices, Etc., to Trustee and Partnership.

      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 Partnership 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: ______________________, or

            (2) the Partnership 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
      Partnership addressed to it at 1717 South Boulder Avenue, Suite 600,

      Partnership.

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 (if international mail, by
air mail), 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 any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders. Any notice mailed to a Holder in the manner herein prescribed
shall be conclusively deemed to have been received by such Holder, regardless of
whether such Holder actually receives such notice.


                                      -10-
<PAGE>
      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 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.

bind its successors and assigns, whether so expressed or not.

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 Debt and the Holders, 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 at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of the Securities of any series which specifically
states that such provision shall apply in lieu of this Section)) payment of
interest or principal (and premium, if any) need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date or Redemption Date, or at the Stated Maturity, provided that no
interest shall accrue for the period from and after such Interest Payment Date,
Redemption Date or Stated Maturity, as the case may be.

Act required or permitted under this Indenture shall be in the English language,

hereunder are non-recourse to the General Partners, and their respective
Affiliates (other than the Partnership), and payable only out of cash flow and
assets of the Partnership. The Trustee, and each Holder of a Security by its

Affiliates other than the Partnership, nor their respective assets) shall be
liable for any of the obligations of the Partnership under this Indenture or
such Securities, and (2) no director, officer, employee, stockholder or

overdue installment of interest]. [If applicable, insert -- The amount of
interest payable for any period shall be computed on the basis of twelve 30-day
months and a 360-day year. The amount of interest payable for any partial period
shall be computed on the basis of a 360-day year of twelve 30-day months and 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) with the same force and effect as if made on the date the payment was
originally payable. A "Business Day" shall mean, when used with respect to any

Payment Date. Any such interest 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 of this series
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 or automated quotation system on which the Securities of
this series may be listed or traded, and upon such notice as may be required by
such exchange or automated quotation system, all as more fully provided in such
Indenture].

      [If the Security is not to bear interest prior to Maturity, insert -- The
principal of this Security shall not bear interest except in the case of a
default in payment of principal upon acceleration, upon redemption or at Stated
Maturity and in such case the overdue principal of this Security shall bear
interest at the rate of ___% per annum, which shall accrue from the date of such
default in payment to the date payment of such principal has been made or duly
provided for. Interest on any overdue principal shall be payable on demand. Any
such interest on any overdue principal that is not so paid on demand shall bear
interest at the rate of ___% per annum, which shall accrue from the date of such
demand for payment to the date payment of such interest has been made or duly
provided for, and such interest shall also be payable on demand.]

      [If a Global Security, insert -- Payment of the principal of [(and
premium, if any)] and [if applicable, insert -- anY such] interest on this

designate, by [United States Dollar] [state other currency] check drawn on, or
transfer to a [United States Dollar] account maintained by the payee with, a
bank in The City of New York (so long as the applicable Paying Agent has
received proper transfer instructions in writing at least [__] days prior to the
payment date)] [if applicable, insert -- ; provided, however, that payment of
interest may be made at the option of the Partnership by [United States Dollar]
[state other currency] check mailed to the addresses of the Persons entitled

to a [United States Dollar] [state other currency] account maintained by the
payee with a bank in The City of New York [state other Place of Payment] (so

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

and (2) of interest on any overdue principal and overdue interest, all of the

affected under the Indenture at any time by the Partnership and the Trustee with
the consent of not less than the Holders of a majority in aggregate principal
amount of the Outstanding Securities of all series to be affected (voting as one
class). The Indenture also contains provisions permitting the Holders of a
majority in aggregate principal amount of the Outstanding Securities of all
affected series (voting as one class), on behalf of the Holders of all
Securities of such series, to waive compliance by the Partnership with certain
provisions of the Indenture. The Indenture permits, with certain exceptions as
therein provided, the Holders of a majority in principal amount of Securities of
any series then Outstanding to waive past defaults under the Indenture with
respect to such series 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,
regardless of whether notation of such consent or waiver is made upon this
Security.

of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or [any premium or] interest
hereon on or after the respective due dates expressed herein.

of the Indenture shall alter or impair the obligation of the Partnership, which
is absolute and unconditional, to pay the principal of and [any premium and]
interest on this Security at the times, place(s) and rate, and in the coin or
currency, herein prescribed.

      [If a Global Security, insert -- This Global Security or portion hereof
may not be exchanged for Definitive Securities of this series except in the
limited circumstances provided in the Indenture.

described in the Indenture and will not be considered the Holders thereof for
any purpose under the Indenture.]

subject to certain limitations therein set forth, the transfer of this Security
is registerable in the Security Register, upon surrender of this Security for
registration of transfer at the office or agency of the Partnership in [if
applicable, insert -- any place where the principal of and any premium and
interest on this Security are payable] [if applicable, insert -- The City of New
York [, or, subject to any laws or regulations applicable thereto and to the
right of the Partnership (limited as provided in the Indenture) to rescind the
designation of any such transfer agent, at the [main] offices of _______________
____________ in __________________ and _________________ in ______________ or at
such other offices or agencies as the Partnership may designate]], duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Partnership 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 this series and of like tenor, of authorized denominations and for
the same aggregate principal amount, will be issued to the designated transferee
or transferees.]

      The Securities of this series are issuable only in registered form without
coupons in denominations of U.S.$ [state other currency] and any integral
multiple thereof. As provided in the Indenture and subject to certain
limitations therein set forth, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination, as requested by the Holder surrendering
the same.

      No service charge shall be made for any such registration of transfer or
exchange, but the Partnership 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 Partnership, the Trustee and any agent of the Partnership or the Trustee may
treat the Person in whose name this Security is registered as the owner hereof
for all purposes, regardless of whether this Security is overdue, and neither
the Partnership, the Trustee nor any such agent shall be affected by notice to
the contrary.

      This Security is subordinated in right of payment to Senior Debt, to the
extent provided in the Indenture.

thereunder, including this Security, are non-recourse to Alliance Resource

LLC (the "Special General Partner" and, together with the Managing General
Partner, the "General Partners") and their Affiliates (other than the
Partnership), and payable only out of cash flow and assets of the Partnership.
The Trustee, and each Holder of a Security by its acceptance hereof, will be
deemed to have agreed in the Indenture that (1) neither the General Partners nor
their assets (nor any of their Affiliates other than the Partnership, nor their
respective assets) shall be liable for any of the obligations of the Partnership
under the Indenture or such Securities, including this Security, and (2) no
director, officer, employee, stockholder or unitholder, as such, of the
Partnership, the Trustee, the General Partners or any Affiliate of any of the
foregoing entities shall have any personal liability in respect of the
obligations of the Partnership under the Indenture or such Securities by reason
of his, her or its status.

      The Indenture contains provisions that relieve the Partnership from the
obligation to comply with certain restrictive covenants in the Indenture and for
satisfaction and discharge at any time of the entire indebtedness upon
compliance by the Partnership with certain conditions set forth in the
Indenture.

such series as shall be specified therein and may provide that it shall
represent the aggregate amount of Outstanding Securities from time to time
endorsed thereon and that the aggregate amount of Outstanding Securities
represented thereby may from time to time be reduced or increased, as the case
may be, to reflect exchanges. Any endorsement of a Global Security to reflect
the amount, or any reduction or increase in the amount, of Outstanding
Securities represented thereby shall be made in such manner and upon
instructions given by such Person or Persons as shall be specified therein or in

Security represented by a Global Security if such Security was never issued and
sold by the Partnership and the Partnership delivers to the Trustee the Global
Security together with a Partnership Order (which need not comply with Section
102 and need not be accompanied by an Opinion of Counsel) with regard to the
reduction or increase, as the case may be, in the principal amount of Securities
represented thereby, together with the written statement contemplated by the

      to an index, the manner in which such amounts shall be determined;

      Securities of the series is to be payable, at the election of the

      payable, the currency, currencies or currency units in which payment of
      the principal of and any premium and interest on Securities of such series
      as to which such election is made shall be payable, and the periods within
      which and the terms and conditions upon which such election is to be made;

            (14) the right, if any, of the Partnership to defer payments of
      interest by extending the interest payment periods and specify the
      duration of such extension, the Interest Payment Dates on which such

            (16) if and as applicable, that the Securities of the series shall
      be issuable in whole or in part in the form of one or more Global
      Securities (and whether in temporary or permanent global form) and, in
      such case, the Depositary or Depositaries for such Global Security or
      Global Securities and any circumstances other than those set forth in
      Section 305 in which any such Global Security may be transferred to, and
      registered and exchanged for Securities registered in the name of, a
      Person other than the Depositary for such Global Security or a nominee

      Securities may be defeased or discharged;

            (20) if other than the Trustee, the identity of the Security

                                      -21-
<PAGE>
            (21) any restrictions or other provisions with respect to the
      transfer or exchange of the Securities;

            (22) the assets, if any, that are pledged as security for the
      payment of the Securities; and

            (23) any other terms of the Securities of the series (which terms
      shall not be inconsistent with the provisions of this Indenture, except as
      permitted by Section 901(5)).

      All Securities of any one series shall be substantially identical except
as to denomination and except as may otherwise be provided in or pursuant to the
Board Resolution referred to above and (subject to Section 303) set forth, or
determined in the manner provided, in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

      All Securities of any one series need not be issued at the same time and,
unless otherwise provided, a series may be reopened, without the consent of the
Holders, for increases in the aggregate principal amount of such series of
Securities and issuances of additional Securities of such series or for the
establishment of additional terms with respect to the Securities of such series.

      If any of the terms of the series are established by action taken by or
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by an authorized officer or other authorized person of the
Managing General Partner on behalf of the Partnership and delivered to the
Trustee at or prior to the delivery of the Officers' Certificate setting forth,
or providing the manner for determining, the terms of the series.

      With respect to Securities of a series subject to a Periodic Offering,
such Board Resolution or Officers' Certificate may provide general terms for
Securities of such series and provide either that the specific terms of
particular Securities of such series shall be specified in a Partnership Order,
or that such terms shall be determined by the Partnership, or one or more of the
Partnership's agents designated in an Officers' Certificate, in accordance with
a Partnership Order.

SECTION 302. Denominations.

      The Securities of each series shall be issuable only in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301. In the absence of any such specified denomination with respect to
the Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

SECTION 303. Execution, Authentication, Delivery and Dating.

      The Securities shall be executed on behalf of the Partnership by the
Chairman of the Board, Chief Executive Officer, Chief Financial Officer,
President or any Vice President of the Managing General Partner and need not be
attested. The signature of any of these officers on the Securities may be manual
or facsimile.


                                      -22-
<PAGE>
      Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Managing General Partner shall bind
the Partnership, 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 Partnership may deliver Securities of any series executed by the
Partnership to the Trustee for authentication, together with a Partnership Order
for the authentication and delivery of such Securities, and the Trustee in
accordance with the Partnership Order shall authenticate and deliver such
Securities; provided, however, that in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of oral or electronic instructions from
the Partnership or its duly authorized agents, thereafter promptly confirmed in
writing) acceptable to the Trustee as may be specified by or pursuant to a
Partnership Order delivered to the Trustee prior to the time of the first
authentication of Securities of such series. If the form or terms of the
Securities of the series have been established in or pursuant to one or more
Board Resolutions as permitted by Sections 201 and 301, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating,

            (1) if the form or forms of such Securities have been established by
      or pursuant to Board Resolution as permitted by Section 201, that such
      form or forms have been established in conformity with the provisions of
      this Indenture;

            (2) if the terms of such Securities have been, or in the case of
      Securities of a series offered in a Periodic Offering, will be,
      established by or pursuant to a Board Resolution as permitted by Section
      301, that such terms have been, or in the case of Securities of a series
      offered in a Periodic Offering, will be, established in conformity with
      the provisions of this Indenture, subject, in the case of Securities of a
      series offered in a Periodic Offering, to any conditions specified in such
      Opinion of Counsel; and

            (3) that such Securities, when authenticated and delivered by the
      Trustee and issued by the Partnership in the manner and subject to any
      conditions specified in such Opinion of Counsel, will constitute valid and
      legally binding obligations of the Partnership enforceable in accordance
      with their terms, subject to bankruptcy, insolvency, fraudulent transfer,
      reorganization, moratorium and similar laws of general applicability
      relating to or affecting creditors' rights and to general equity
      principles.

      If such form or forms or terms have been so established, the Trustee shall
not be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

      Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Partnership


                                      -23-
<PAGE>
Order and Opinion of Counsel otherwise required pursuant to such preceding
paragraph at or prior to the time of authentication of each Security of such
series if such documents are delivered at or prior to the authentication upon
original issuance of the first Security of such series to be issued.

      With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Partnership of any of such
Securities, the form or forms and terms thereof and the legality, validity,
binding effect and enforceability thereof, upon the Opinion of Counsel and the
other documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

      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 of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

      Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the
Partnership, and the Partnership shall deliver such Security to the Trustee for
cancellation as provided in Section 309 for all purposes of this Indenture, such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304. Temporary Securities.

      Pending the preparation of Definitive Securities of any series, the
Partnership may execute, and upon Partnership 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 of any series are issued, the Partnership will
cause Definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of Definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for Definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Partnership maintained pursuant to Section
1002 for the purpose of exchanges of Securities of such series, without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series the Partnership shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more Definitive Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount and tenor. Until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as Definitive Securities of such series and tenor.


                                      -24-
<PAGE>
SECTION 305. Registration, Registration of Transfer and Exchange.

      The Partnership shall cause to be kept at an office or agency of the
Partnership in The City of New York a register (the register maintained in such
office or in any other office or agency of the Partnership in a Place of Payment
being herein sometimes referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Partnership shall
provide for the registration of Securities and of transfers of Securities. The
Partnership shall, prior to the issuance of any Securities hereunder, appoint
the Trustee as the initial "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided and its corporate
trust office which, at the date hereof, is located at _______________________,
as the initial office or agency in The City of New York where the Security
Register will be maintained. The Partnership may at any time replace such
Security Registrar, change such office or agency or act as its own Security
Registrar. The Partnership will give prompt written notice to the Trustee of any
change of the Security Registrar or of the location of such office or agency.

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

      At the option of the Holder, Securities of any series (except a Global
Security) may be exchanged for other Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Partnership 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 exchange of
Securities shall be the valid obligations of the Partnership, 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 Partnership or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Partnership 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 Partnership 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 1107 not involving any transfer.

      Neither the Trustee nor the Partnership shall be required (1) to issue,
register the transfer of or exchange Securities of any series (or of any series
and specified tenor, as the case may be)


                                      -25-
<PAGE>
during a period beginning at the opening of business 15 days before the day of
mailing of a notice of redemption of Securities of that series selected for
redemption under Section 1103 and ending at the close of business on the day of
such mailing, or (2) to register the transfer of or exchange any Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

      Notwithstanding any other provision in this Indenture and except as
otherwise specified as contemplated by Section 301, no Global Security may be
transferred to, or registered or exchanged for Securities registered in the name
of, any Person other than the Depositary for such Global Security or any nominee
thereof, and no such transfer may be registered, except as provided in this
paragraph. Every Security authenticated and delivered upon registration or
transfer of, or in exchange for or in lieu of, a Global Security shall be a
Global Security, except as provided in this paragraph. If (1) (A) the Depositary
for a Global Security notifies the Partnership that it is unwilling or unable to
continue as Depositary for such Global Security or ceases to be a clearing
agency registered under the Exchange Act, and (B) a successor Depositary is not
appointed by the Partnership within 90 days, (2) an Event of Default has
occurred and is continuing with respect to the Securities of such series and the
Security Registrar has received a request from the Depositary to issue
certificated securities in lieu of all or a portion of the Global Securities of
such series (in which case the Partnership shall deliver certificated securities
within 30 days of such request) or (3) the Partnership determines in its sole
discretion that Securities of a series issued in global form shall no longer be
represented by a Global Security, then such Global Security may be exchanged by
such Depositary for Definitive Securities of the same series, of any authorized
denomination and of a like aggregate principal amount and tenor, registered in
the names of, and the transfer of such Global Security or portion thereof may be
registered to, such Persons as such Depositary shall direct.

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

      If any mutilated Security is surrendered to the Trustee, together with
such security or indemnity as may be required by the Partnership or the Trustee
to save each of them and any agent of either of them harmless, the Partnership
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

      If there shall be delivered to the Partnership and the Trustee (1)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (2) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Partnership or the Trustee that such Security has been acquired by a bona
fide purchaser, the Partnership shall execute and the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Security, a new
Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding. If, after the delivery of such new
Security, a bona fide purchaser of the original Security in lieu of which such
new Security was issued presents for payment or registration such original
Security, the Trustee shall be entitled to recover such new Security from the
party to whom it was delivered or any party taking therefrom, except a bona fide
purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by
the Partnership and the Trustee in connection therewith.


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

      Upon the issuance of any new Security under this Section, the Partnership
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 of any series issued pursuant to this Section in
exchange for any mutilated Security or in lieu of any destroyed, lost or stolen
Security shall constitute an original additional contractual obligation of the
Partnership, regardless of whether the mutilated, 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 of that series 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.

      Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, 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 of any series 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 Partnership, at its election in each
case, as provided in clause (1) or (2) below:

            (1) The Partnership may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Securities of such series (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 Partnership
      shall notify the Trustee in writing of the amount of Defaulted Interest
      proposed to be paid on each Security of such series and the date of the
      proposed payment, and at the same time the Partnership 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


                                      -27-
<PAGE>
      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
      Partnership of such Special Record Date and, in the name and at the
      expense of the Partnership, 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 of Securities of such series
      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 of such series (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 Partnership may make payment of any Defaulted Interest on
      the Securities of any series in any other lawful manner not inconsistent
      with the requirements of any securities exchange or automated quotation
      system on which such Securities may be listed or traded, and upon such
      notice as may be required by such exchange, if, after notice given by the
      Partnership 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 and Section 305, 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, which were carried by such other
Security.

      For each series of Securities, the Partnership shall, prior to 11:00 a.m.
(New York City time) on each payment date for principal and premium, if any, and
interest, if any, deposit with the Trustee money in immediately available funds
sufficient to make cash payments due on the applicable payment date.

SECTION 308. Persons Deemed Owners.

      Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, prior to due presentment of a Security for
registration of transfer, the Partnership, the Trustee and any agent of the
Partnership or the Trustee may 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 any premium and (subject to Sections 305 and 307) any interest
on such Security and for all other purposes whatsoever, regardless of whether
such Security is overdue, and neither the Partnership, the Trustee nor any agent
of the Partnership or the Trustee shall be affected by notice to the contrary.

      No holder of any beneficial interest in any Global Security held on its
behalf by a Depositary shall have any rights under this Indenture with respect
to such Global Security, and such Depositary may be treated by the Partnership,
the Trustee and any agent of the Partnership or the Trustee as the owner of such
Global Security for all purposes whatsoever. None of the Partnership, the
Trustee nor any agent of the Partnership or the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account


                                      -28-
<PAGE>
of beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

SECTION 309. Cancellation.

      All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Partnership may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Partnership may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Partnership has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in accordance with its
customary procedures, and the Trustee shall thereafter deliver to the
Partnership a certificate with respect to such disposition.

SECTION 310. Computation of Interest.

      Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months and interest on
the Securities of each series for any partial period shall be computed on the
basis of a 360-day year of twelve 30-day months and the number of days elapsed
in any partial month.

SECTION 311. CUSIP Numbers.

      The Partnership in issuing the Securities may use "CUSIP" numbers (in
addition to the other identification numbers printed on the Securities), and, if
so, the Trustee shall use "CUSIP" numbers in notices of redemption as a
convenience to Holders; provided, however, that any such notice may state that
no representation is made as to the correctness of such "CUSIP" numbers either
as printed on the Securities or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on
the Securities, and any such redemption shall not be affected by any defect in
or omission of such "CUSIP" numbers.

                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

SECTION 401. Satisfaction and Discharge of Indenture.

      This Indenture shall upon Partnership Request cease to be of further
effect with respect to Securities of any series (except as to any surviving
rights of registration of transfer or exchange of such Securities herein
expressly provided for), and the Trustee, at the expense of the Partnership,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture with respect to such Securities, when:


                                      -29-
<PAGE>
            (1) either

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

            delivered to the Trustee for cancellation; or

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

                        (i) have become due and payable,

                        (ii) will become due and payable at their Stated
                  Maturity within one year, or

                        (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Partnership,

and the Partnership in the case of (i), (ii) or (iii) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust for
this purpose an amount of money in the currency or currency units in which such
Securities are payable sufficient to pay and discharge the entire indebtedness
on such Securities not theretofore delivered to the Trustee for cancellation,
for principal and any premium and 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 Partnership has paid or caused to be paid all other sums
      payable hereunder by the Partnership with respect to such Securities; and

            (3) the Partnership 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 with respect to such Securities have been complied with.

      Notwithstanding the satisfaction and discharge of this Indenture with
respect to Securities of any series, (x) the obligations of the Partnership to
the Trustee under Section 607, the obligations of the Trustee to any
Authenticating Agent under Section 614 and the right of the Trustee to resign
under Section 610 shall survive, and (y) if money shall have been deposited with
the Trustee pursuant to subclause (B) of clause (1) of this Section, the
obligations of the Partnership and/or the Trustee under Sections 402, 606, 701
and 1002 and the last paragraph of Section 1003 shall survive.

SECTION 402. Application of Trust Money.

      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 Partnership acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                    REMEDIES

SECTION 501. Events of Default.

      "Event of Default," wherever used herein with respect to Securities of any
series, means any one of the following events (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) default in the payment of any interest upon any Security of that
      series when it becomes due and payable, and continuance of such default
      for a period of 30 days (regardless of whether such payment is prohibited
      by the provisions of Article XIV hereof); or

            (2) default in the payment of the principal of (or premium, if any,
      on) any Security of that series at its Maturity (regardless of whether
      such payment is prohibited by the provisions of Article XIV hereof); or

            (3) default in the performance, or breach, of any term, covenant or
      warranty of the Partnership in this Indenture (other than a term, covenant
      or warranty a default in whose performance or whose breach is elsewhere in
      this Section specifically dealt with or which has expressly been included
      in this Indenture solely for the benefit of series of Securities other
      than that series), and continuance of such default or breach for a period
      of 60 days after there has been given, by registered or certified mail, to
      the Partnership by the Trustee or to the Partnership and the Trustee by
      the Holders of at least 25% in principal amount of the Outstanding
      Securities of that series a written notice specifying such default or
      breach and requiring it to be remedied and stating that such notice is a
      "Notice of Default" hereunder; or

            (4) the Partnership pursuant to or within the meaning of any
      Bankruptcy Law (A) commences a voluntary case, (B) consents to the entry
      of any order for relief against it in an involuntary case, (C) consents to
      the appointment of a Custodian of it or for all or substantially all of
      its property, or (D) makes a general assignment for the benefit of its
      creditors; or


                                      -31-
<PAGE>
            (5) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that (A) is for relief against the Partnership in
      an involuntary case, (B) appoints a Custodian of the Partnership or for
      all or substantially all of its property, or (C) orders the liquidation of
      the Partnership; and the order or decree remains unstayed and in effect
      for 90 days; or

            (6) any other Event of Default provided as contemplated by Section
      301 with respect to Securities of that series.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default (other than an Event of Default specified in clause
(4) or (5) of Section 501 hereof) with respect to Securities of any series at
the time Outstanding occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount of (or,
if any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof), and accrued but unpaid interest, if any, on all of the
Securities of that series to be due and payable immediately, by a notice in
writing to the Partnership (and to the Trustee if given by Holders), and upon
any such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in clause (4) or
(5) of Section 501 hereof occurs, the principal amount of (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof), and accrued but unpaid interest, if any, on all of the Securities then
outstanding shall ipso facto become and be immediately due and payable without
declaration, notice or other act on the part of the Trustee or any Holder.

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

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

                  (A) all overdue interest on all Securities of that series,

                  (B) the principal of (and premium, if any, on) any Securities
            of that series which have become due otherwise than by such
            declaration of acceleration and any interest thereon at the rate or
            rates prescribed therefor in such Securities,

                  (C) to the extent that payment of such interest is lawful,
            interest upon overdue interest at the rate or rates prescribed
            therefor in such Securities, and

                  (D) 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


                                      -32-
<PAGE>
            (2) all Events of Default with respect to Securities of that series,
      other than the non-payment of the principal of Securities of that series
      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 Partnership covenants that if

            (1) default is made in the payment of any interest on any Security
      when such interest becomes due and payable and such default continues for
      a period of 30 days (regardless of whether such payment is prohibited by
      the provisions of Article XIV hereof), or

            (2) default is made in the payment of the principal of (or premium,
      if any, on) any Security at the Maturity thereof (regardless of whether
      such payment is prohibited by the provisions of Article XIV hereof),

the Partnership 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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such 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 the Partnership fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Partnership or any other obligor upon such Securities and collect
the moneys adjudged or decreed to be payable in the manner provided by law out
of the property of the Partnership or any other obligor upon such Securities,
wherever situated.

      Subject to Article XIV, if an Event of Default with respect to Securities
of any series occurs and is continuing, the Trustee may in its discretion
proceed to protect and enforce its rights and the rights of the Holders of
Securities of such series by such appropriate judicial proceedings as the
Trustee shall deem most effectual 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 Partnership or any
other obligor upon the Securities, their property or their creditors, the
Trustee shall be entitled and empowered, by


                                      -33-
<PAGE>
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; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

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.

      Any money or property collected or to be applied 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 or property
on account of principal or any premium or 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: Subject to Article XIV, to the payment of the amounts then due and
              unpaid for principal of and any premium and 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 any premium and interest,
              respectively; and

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


                                      -34-

SECTION 507. Limitation on Suits.

      No Holder of any Security of any series 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 with respect to the Securities of that
      series;

            (2) the Holders of not less than 25% in principal amount of the
      Outstanding Securities of that series 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 and, if requested, provided
      to the Trustee reasonable security or indemnity 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 and, if requested, provision of security or 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 of that series;

it being understood and intended that no one or more of such 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 of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium 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 any premium and (subject to Sections 305 and
307) interest on such Security on the respective Stated Maturities 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 in every such case, subject to any determination in such
proceeding, the Partnership, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder, and thereafter
all rights


                                      -35-
<PAGE>
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 Securities 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 aggregate principal amount of the Outstanding
Securities of any series 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, with respect to the
Securities of such series; provided, however, that

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

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

            (3) subject to the provisions of Section 601, the Trustee shall have
      the right to decline to follow any such direction if the Trustee in good
      faith shall determine that the proceeding so directed would involve the
      Trustee in personal liability or would otherwise be contrary to applicable
      law.

SECTION 513. Waiver of Past Defaults.

      The Holders of a majority in aggregate principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default hereunder with respect to such series and its
consequences, except


                                      -36-
<PAGE>
            (1) a continuing default in the payment of the principal of or any
      premium or interest on any Security of such series, or

            (2) a default in respect of a covenant or provision hereof which
      under Article IX cannot be modified or amended without the consent of the
      Holder of each Outstanding Security of such series 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 suit 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, however, 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
Partnership.

SECTION 515. Waiver of Usury, Stay or Extension Laws.

      The Partnership covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Partnership (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any such
law and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE VI

                                   THE TRUSTEE

SECTION 601. Certain Duties and Responsibilities.

      The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. No provision of this 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 security or indemnity satisfactory to it against such
risk or liability is not reasonably assured to it. Regardless of whether 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.


                                      -37-

SECTION 602. Notice of Defaults.

      If a Default occurs and is continuing with respect to the Securities of
any series, the Trustee shall, within 90 days after it occurs, transmit, in the
manner and to the extent provided in Section 313(c) of the Trust Indenture Act,
notice of all uncured or unwaived Defaults known to it; provided, however, that,
except in the case of a Default in payment on the Securities of any series, the
Trustee may withhold the notice if it determines in good faith that withholding
such notice is in the interests of Holders of Securities of such series;
provided, further, however, that, in the case of any default or breach of the
character specified in Section 501(3) with respect to the Securities of such
series, no such notice to Holders shall be given until at least 60 days after
the occurrence thereof.

SECTION 603. Certain Rights of Trustee.

      Subject to the provisions of Section 601:

            (1) the Trustee may rely on and shall be 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 or presented
      by the proper party or parties;

            (2) any request, direction, order or demand of the Partnership
      mentioned herein shall be sufficiently evidenced by a Partnership Request
      or Partnership Order (other than delivery of any Security to the Trustee
      for authentication and delivery pursuant to Section 303, which shall be
      sufficiently evidenced as provided therein) and any resolution of the
      Board of Directors shall be sufficiently evidenced by a Board Resolution;

            (3) whenever in the administration of this Indenture the Trustee
      shall deem it desirable that a matter be proved or established prior to
      taking, suffering or omitting any action hereunder, the Trustee (unless
      other evidence be herein specifically prescribed) may, in the absence of
      bad faith on its part, rely upon an Officers' Certificate;

            (4) the Trustee may consult with counsel and the written advice of
      such counsel or any Opinion of Counsel 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 reliance thereon;

            (5) 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 any of the Holders pursuant to this Indenture, unless such
      Holders shall have offered to the Trustee security or indemnity
      satisfactory to it against the costs, expenses and liabilities which might
      be incurred by it in compliance with such request or direction;

            (6) the 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


                                      -38-
<PAGE>
      or other paper or document, but the Trustee, in its discretion, may,
      without obligation to do so, make such further inquiry or investigation
      into such facts or matters as it may see fit;

            (7) the Trustee may execute any of the trusts or powers hereunder or
      perform any duties hereunder either directly or by or through agents or
      attorneys and the 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; and

            (8) the Trustee may request that the Partnership deliver an
      Officers' Certificate setting forth the names of individuals and/or titles
      of officers authorized at such time to take specified actions pursuant to
      this Indenture, which Officers' Certificate may be signed by any person
      authorized to sign an Officers' Certificate, including any person
      specified as so authorized in any such certificate previously delivered
      and not superseded.

SECTION 604. Not Responsible for Recitals or Issuance of Securities.

      The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the
Partnership, and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. Neither the Trustee nor any Authenticating
Agent makes any representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee or any Authenticating Agent shall
not be accountable for the use or application by the Partnership of Securities
or the proceeds thereof.

SECTION 605. May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Partnership, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Partnership with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

SECTION 606. Money Held in Trust.

      Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Partnership.

SECTION 607. Compensation and Reimbursement.

      The Partnership agrees:

            (1) to pay to the Trustee from time to time reasonable compensation
      for all services rendered by it hereunder (which compensation shall not be
      limited by any provision of law in regard to the compensation of a trustee
      of an express trust);


                                      -39-
<PAGE>
            (2) to reimburse the Trustee upon its request for all reasonable
      expenses, disbursements and advances incurred or made by the Trustee in
      accordance with any provision of this Indenture (including the reasonable
      compensation and the expenses and disbursements of its agents and
      counsel), except any such expense, disbursement or advance as may be
      attributable to its negligence or bad faith; and

            (3) to indemnify the Trustee for, and to hold it harmless against,
      any loss, liability or expense incurred without negligence or bad faith on
      its part, arising out of or in connection with the acceptance or
      administration of the trust or trusts hereunder, including the costs and
      expenses of defending itself against any claim or liability in connection
      with the exercise or performance of any of its powers or duties hereunder.

      The obligations of the Partnership under this Section to compensate the
Trustee and to pay or reimburse the Trustee for expenses, disbursements and
advances shall constitute additional indebtedness hereunder.

      Without limiting any rights available to the Trustee under applicable law,
when the Trustee incurs expenses or renders services in connection with an Event
of Default specified in Section 501(4) or Section 501(5), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for such services are intended to constitute expenses of
administration under any applicable Bankruptcy Law.

      The provisions of this Section shall survive the satisfaction and
discharge of this Indenture and the defeasance of the Securities.

SECTION 608. Disqualification; Conflicting Interests.

      If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

SECTION 609. Corporate Trustee Required; Eligibility.

      There shall at all times be one or more Trustees hereunder with respect to
the Securities of each series, at least one of which shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus required by the Trust Indenture Act. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of a 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 capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 610. Resignation and Removal; Appointment of Successor.

      No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 611.


                                      -40-
<PAGE>
      The Trustee may resign at any time with respect to the Securities of one
or more series by giving written notice thereof to the Partnership. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

      The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Partnership.

      If at any time:

            (1) the Trustee shall fail to comply with Section 608 after written
      request therefor by the Partnership or by any Holder who has been a bona
      fide Holder of a Security for at least six months, or

            (2) the Trustee shall cease to be eligible under Section 609 and
      shall fail to resign after written request therefor by the Partnership or
      by any such Holder, or

            (3) the Trustee shall become incapable of acting or shall be
      adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
      property shall be appointed or any public officer shall take charge or
      control of the Trustee or of its property or affairs for the purpose of
      rehabilitation, conservation or liquidation, then, in any such case, (A)
      the Partnership, acting pursuant to the authority of a Board Resolution,
      may remove the Trustee with respect to all Securities, or (B) 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 with respect to all Securities and the appointment of a
      successor Trustee or Trustees.

      If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause, with respect to
the Securities of one or more series, the Partnership, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Partnership and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Partnership. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Partnership or the Holders and accepted appointment in the manner required by
Section 611, any Holder who has


                                      -41-
<PAGE>
been a bona fide Holder of a Security of such series 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 with
respect to the Securities of such series.

      The Partnership shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

SECTION 611. Acceptance of Appointment by Successor.

            (1) In case of the appointment hereunder of a successor Trustee with
      respect to all Securities, every such successor Trustee so appointed shall
      execute, acknowledge and deliver to the Partnership 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; but, on the request of the Partnership or the successor
      Trustee, such retiring Trustee shall, upon payment of its charges, 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.

            (2) In case of the appointment hereunder of a successor Trustee with
      respect to the Securities of one or more (but not all) series, the
      Partnership, the retiring Trustee and each successor Trustee with respect
      to the Securities of one or more series shall execute and deliver an
      indenture supplemental hereto wherein each successor Trustee shall accept
      such appointment and which (A) shall contain such provisions as shall be
      necessary or desirable to transfer and confirm to, and to vest in, each
      successor Trustee all the rights, powers, trusts and duties of the
      retiring Trustee with respect to the Securities of that or those series to
      which the appointment of such successor Trustee relates, (B) if the
      retiring Trustee is not retiring with respect to all Securities, shall
      contain such provisions as shall be deemed necessary or desirable to
      confirm that all the rights, powers, trusts and duties of the retiring
      Trustee with respect to the Securities of that or those series as to which
      the retiring Trustee is not retiring shall continue to be vested in the
      retiring Trustee, and (C) shall add to or change any of the provisions of
      this Indenture as shall be necessary to provide for or facilitate the
      administration of the trusts hereunder by more than one Trustee, it being
      understood that nothing herein or in such supplemental indenture shall
      constitute such Trustees as co-trustees of the same trust and that each
      such Trustee shall be trustee of a trust or trusts hereunder separate and
      apart from any trust or trusts hereunder administered by any other such
      Trustee; and upon the execution and delivery of such supplemental
      indenture the resignation or removal of the retiring Trustee shall become
      effective to the extent provided therein and each 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 with respect
      to the Securities of that or those series to which the appointment of such
      successor Trustee


                                      -42-
<PAGE>
      relates, but, on request of the Partnership or any successor Trustee, such
      retiring Trustee shall, upon payment of its charges, duly assign, transfer
      and deliver to such successor Trustee all property and money held by such
      retiring Trustee hereunder with respect to the Securities of that or those
      series to which the appointment of such successor Trustee relates.

            (3) Upon request of any such successor Trustee, the Partnership
      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 referred to in paragraph (1) or (2) of this Section, as the case
      may be.

            (4) 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.

SECTION 612. Merger, Conversion, Consolidation or Succession to Business.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which 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 Partnership.

      If and when the Trustee shall be or become a creditor of the Partnership
or any other obligor upon the Securities, the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Partnership or any such other obligor.

SECTION 614. Appointment of Authenticating Agent.

      The Trustee (upon notice to the Partnership) may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue (in accordance with procedures acceptable to
the Trustee) and upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Partnership and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as


                                      -43-
<PAGE>
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent 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 Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

      Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate agency or corporate trust business of such Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or such Authenticating
Agent.

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Partnership. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Partnership. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Partnership. Any successor Authenticating
Agent upon acceptance of its appointment hereunder shall become vested with all
the rights, powers and duties of its predecessor hereunder, with like effect as
if originally named as an Authenticating Agent. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

      Except with respect to an Authenticating Agent appointed at the request of
the Partnership, the Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section.

      If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

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

      The rights of the Holders to communicate with other Holders with respect
to their rights under this Indenture or under the Securities, and the
corresponding rights and privileges of the Trustee, shall be as provided by the
Trust Indenture Act.

      Every Holder of Securities, by receiving and holding the same, agrees with
the Partnership and the Trustee that neither the Partnership nor the Trustee nor
any agent of either of them shall be held accountable by reason of any

      or interest on any Security is payable;

            (6) change the redemption right of any Holder;

            (7) impair the right to institute suit for the enforcement of any
      payment of principal of, premium, if any, or interest on, any Security;

            (8) reduce the percentage in principal amount of Securities required
      for any such supplemental indenture or for any waiver provided for in this
      Indenture;

            (9) reduce quorum or voting requirements;

            (10) change the Partnership's obligation to maintain an office or
      agency for payment of Securities and the other matters specified herein;

            (11) modify the provisions of this Indenture with respect to the
      subordination of the Securities in a manner adverse to the Holders or so
      as to adversely affect any right to convert or exchange any Security into
      any other security, or

            (12) modify any of the provisions of this Indenture relating to the
      execution of supplemental indentures with the consent of Holders of
      Securities which are discussed in this Section or modify any provisions
      relating to the waiver by Holders of Securities of past defaults and
      covenants, except to increase any required percentage or to provide that
      other provisions of this Indenture cannot be modified or waived without
      the consent of the Holder of each Outstanding Security affected thereby.

      A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

      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 receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Officers' Certificate 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 as then in effect.

SECTION 906. Reference in Securities to Supplemental Indentures.

      Securities of any series authenticated and delivered after the execution
of any supplemental indenture pursuant to this Article may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to
any matter provided for in such supplemental indenture. If the Partnership shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Partnership, to any such supplemental indenture
may be prepared and executed by the Partnership and authenticated and delivered
by the Trustee in exchange for Outstanding Securities of such series.

                                    ARTICLE X

                                    COVENANTS

SECTION 1001. Payment of Principal, Premium and Interest.

      The Partnership covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.


                                      -50-
<PAGE>
SECTION 1002. Maintenance of Office or Agency.

      The Partnership will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Partnership in respect of the Securities of that series and this
Indenture may be served. The Partnership 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 Partnership 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 Partnership hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

      The Partnership may also from time to time designate one or more other
offices or agencies where the Securities of one or more series 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 Partnership of its obligation to maintain an
office or agency in each Place of Payment for Securities of any series for such
purposes. The Partnership 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.

      Except as otherwise specified with respect to a series of Securities as
contemplated by Section 301, the Partnership hereby initially designates as the
Place of Payment for each series of Securities The City and State of New York,
and initially appoints the Trustee at its Corporate Trust Office as the
Partnership's office or agency for each such purpose in such city.

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

      If the Partnership or any of its Subsidiaries shall at any time act as
Paying Agent with respect to any series of Securities, it will, on or before
each due date of the principal of or any premium or interest on any of the
Securities of that series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal and any premium
and 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 Partnership shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, 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 Partnership will promptly notify the Trustee of its action or
failure so to act.

      The Partnership will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) hold all sums held by it for
the payment of the principal of (and premium, if any) or interest, if any, on
Securities of that series in trust for the benefit of the Persons entitled
thereto until such sums shall be paid to such Persons or otherwise disposed of
as herein provided; (2) give the


                                      -51-
<PAGE>
Trustee notice of any default by the Partnership (or any other obligor upon the
Securities of that series) in the making of any payment of principal (and
premium, if any) or interest, if any, on the Securities of that series; and (3)
during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent for payment in respect of the Securities of that series.

      The Partnership may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Partnership Order direct any Paying Agent to pay, to the Trustee all sums
held in trust by the Partnership or such Paying Agent, such sums to be held by
the Trustee upon the same trusts as those upon which such sums were held by the
Partnership or such Paying Agent; and, upon such payment by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Partnership, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Partnership on Partnership Request, or (if then held by the
Partnership) shall be discharged from such trust; and the Holder of such
Security shall thereafter, as an unsecured general creditor, look only to the
Partnership for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Partnership as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Partnership cause to be published once, in an Authorized
Newspaper in each Place of Payment with respect to such series, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Partnership.

SECTION 1004. Statement by Officers as to Default.

      The Partnership will deliver to the Trustee, within 150 days after the end
of each fiscal year of the Partnership ending after the date hereof, an
Officers' Certificate, stating to the best knowledge of the signer thereof
whether the Partnership is in default in the performance and observance of any
of the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the
Partnership shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge.

SECTION 1005. Existence.

      Subject to Article VIII, the Partnership will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and statutory) and franchises; provided, however, that the
Partnership shall not be required to preserve any such right or franchise if it
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Partnership.


                                      -52-
<PAGE>
SECTION 1006. Waiver of Certain Covenants.

      The Partnership may omit in any particular instance to comply with any
term, provision or condition set forth in Section 1005 with respect to the
Securities of any series if before the time for such compliance the Holders of
at least a majority in aggregate principal amount of the Outstanding Securities
of all affected series (voting as one class) shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Partnership and
the duties of the Trustee in respect of any such term, provision or condition
shall remain in full force and effect.

      A waiver which changes or eliminates any term, provision or condition of
this Indenture which has expressly been included solely for the benefit of one
or more particular series of Securities, or which modifies the rights of the
Holders of Securities of such series with respect to such term, provision or
condition, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities of any other series.

                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

SECTION 1101. Applicability of Article.

      Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.

SECTION 1102. Election to Redeem; Notice to Trustee.

      The election of the Partnership to redeem any Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Partnership of less than all the Securities of any series, the Partnership
shall, not less than 30 nor more than 60 days prior to the Redemption Date fixed
by the Partnership (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date, of the principal amount of
Securities of such series to be redeemed and, if applicable, of the tenor of the
Securities to be redeemed. In the case of any redemption of Securities (1) prior
to the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, or (2) pursuant to an election
of the Partnership which is subject to a condition specified in the terms of
such Securities, the Partnership shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restriction or condition.

SECTION 1103. Selection by Trustee of Securities to be Redeemed.

      If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed),
the particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by lottery for


                                      -53-
<PAGE>
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

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

      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 1104. Notice of Redemption.

      Notice of redemption shall be given by first-class mail (if international
mail, by air 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 state:

            (1) the Redemption Date,

            (2) the Redemption Price,

            (3) if less than all the Outstanding Securities of any series and of
      a specified tenor are to be redeemed, the identification (and, in the case
      of partial redemption of any Securities, the principal amounts) of the
      particular Securities to be redeemed,

            (4) 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,

            (5) the place or places where such Securities are to be surrendered
      for payment of the Redemption Price, and

            (6) that the redemption is for a sinking fund, if such is the case.

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

SECTION 1105. Deposit of Redemption Price.

      On or prior to any Redemption Date, the Partnership shall deposit with the
Trustee or with a Paying Agent (or, if the Partnership 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.


                                      -54-
<PAGE>
SECTION 1106. 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
Partnership 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 Partnership at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that, unless otherwise
specified as contemplated by Section 301, 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 and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

SECTION 1107. 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 Partnership or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Partnership and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Partnership shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same series
and of like tenor, 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.

                                   ARTICLE XII

                                  SINKING FUNDS

SECTION 1201. Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

      The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.


                                      -55-
<PAGE>
SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.

      The Partnership (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption), and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Partnership pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

SECTION 1203. Redemption of Securities for Sinking Fund.

      Not less than 45 days prior to each sinking fund payment date for any
series of Securities (unless a shorter period shall be satisfactory to the
Trustee), the Partnership will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited, and will also deliver to the Trustee any
Securities to be so delivered. Not less than 30 days before each such sinking
fund payment date the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Partnership in the manner provided in Section 1104. Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1106 and 1107.

                                  ARTICLE XIII
                                   DEFEASANCE

SECTION 1301. Applicability of Article.

      The provisions of this Article shall be applicable to each series of
Securities except as otherwise specified as contemplated by Section 301 for
Securities of such series.

SECTION 1302. Legal Defeasance.

      In addition to discharge of the Indenture pursuant to Section 401, the
Partnership shall be deemed to have paid and discharged the entire indebtedness
on all the Securities of such a series on the 91st day after the date of the
deposit referred to in clause (1) below, and the provisions of this Indenture
with respect to the Securities of such series shall no longer be in effect
(except as to (i) rights of registration of transfer and exchange of Securities
of such series and the Partnership's right of optional redemption, if any, (ii)
substitution of mutilated, destroyed, lost or stolen Securities, (iii) rights of
Holders of Securities to receive payments of principal thereof and interest
thereon, upon the original stated due dates therefor or on the specified
redemption dates


                                      -56-
<PAGE>
therefor (but not upon acceleration), and remaining rights of the holders to
receive mandatory sinking fund payments, if any, (iv) the rights, obligations,
duties and immunities of the Trustee hereunder, and the Partnership's
obligations in connection therewith (including, but not limited to, Section
607), (v) the rights, if any, to convert or exchange the Securities of such
series, (vi) the rights of the Holders of Securities of such series as
beneficiaries hereof with respect to the property so deposited with the Trustee
payable to all or any of them, and (vii) the obligations of the Partnership
under Section 1002), and the Trustee, at the expense of the Partnership, shall,
upon a Partnership Request, execute proper instruments acknowledging the same,
if the conditions set forth below are satisfied (hereinafter, "defeasance"):

            (1) The Partnership has irrevocably deposited or caused to be
      deposited with the Trustee as trust funds in trust, for the purposes of
      making the following payments, specifically pledged as security for, and
      dedicated solely to, the benefit of the Holders of the Securities of such
      series (A) cash in an amount, or (B) in the case of any series of
      Securities the payments on which may only be made in legal coin or
      currency of the United States, U.S. Government Obligations, maturing as to
      principal and interest at such times and in such amounts as will insure
      the availability of cash, or (C) a combination thereof, certified to be
      sufficient, in the opinion of a nationally recognized firm of independent
      public accountants expressed in a written certification thereof delivered
      to the Trustee, to pay (i) the principal and interest and premium, if any,
      on all Securities of such series on each date that such principal,
      interest or premium, if any, is due and payable or on any Redemption Date
      established pursuant to clause (3) below, and (ii) any mandatory sinking
      fund payments on the dates on which such payments are due and payable in
      accordance with the terms of the Indenture and the Securities of such
      series;

            (2) The Partnership has delivered to the Trustee an Opinion of
      Counsel based on the fact that (A) the Partnership has received from, or
      there has been published by, the Internal Revenue Service a ruling, or (B)
      since the date hereof, there has been a change in the applicable federal
      income tax law, in either case to the effect that, and such opinion shall
      confirm that, the Holders of the Securities of such series will not
      recognize income, gain or loss for federal income tax purposes as a result
      of such deposit, defeasance and discharge and will be subject to federal
      income tax on the same amount and in the same manner and at the same
      times, as would have been the case if such deposit, defeasance and
      discharge had not occurred;

            (3) If the Securities are to be redeemed prior to Stated Maturity
      (other than from mandatory sinking fund payments or analogous payments),
      notice of such redemption shall have been duly given pursuant to this
      Indenture or provision therefor satisfactory to the Trustee shall have
      been made;

            (4) No Event of Default or event which with notice or lapse of time
      or both would become an Event of Default shall have occurred and be
      continuing on the date of such deposit;

            (5) Such defeasance shall not cause the Trustee to have a
      conflicting interest within the meaning of the Trust Indenture Act
      (assuming all Securities are in default within the meaning of such Act);


                                      -57-
<PAGE>
            (6) Such defeasance shall not result in a breach or violation of, or
      constitute a default under, any other agreement or instrument to which the
      Partnership is a party or by which it is bound;

            (7) Such defeasance shall not result in the trust arising from such
      deposit constituting an investment company within the meaning of the
      Investment Company Act of 1940, as amended, unless such trust shall be
      registered under such Act or exempt from registration thereunder; and

            (8) The Partnership has delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for relating to the defeasance contemplated by this
      provision have been complied with.

      For this purpose, such defeasance means that the Partnership and any other
obligor upon the Securities of such series shall be deemed to have paid and
discharged the entire debt represented by the Securities of such series, which
shall thereafter be deemed to be "Outstanding" only for the purposes of Section
1304 and the rights and obligations referred to in clauses (i) through (vii),
inclusive, of the first paragraph of this Section, and to have satisfied all its
other obligations under the Securities of such series and this Indenture insofar
as the Securities of such series are concerned.

SECTION 1303. Covenant Defeasance.

      The Partnership and any other obligor shall be released on the 91st day
after the date of the deposit referred to in clause (1) below from its
obligations under Sections 704, 801 and 1005 with respect to the Securities of
any series on and after the date the conditions set forth below are satisfied
(hereinafter, "covenant defeasance"), and the Securities of such series shall
thereafter be deemed to be not "Outstanding" for the purposes of any request,
demand, authorization, direction, notice, waiver, consent or declaration or
other action or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed Outstanding for
all other purposes hereunder. For this purpose, such covenant defeasance means
that, with respect to the Securities of such series, the Partnership may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such Section, whether directly or indirectly by
reason of any reference elsewhere herein to such Section or by reason of any
reference in such Section to any other provision herein or in any other document
and such omission to comply shall not constitute a Default or an Event of
Default under Section 501, but, except as specified above, the remainder of this
Indenture and the Securities of such series shall be unaffected thereby. The
following shall be the conditions to application of this Section 1303:

            (1) The Partnership has irrevocably deposited or caused to be
      deposited with the Trustee as trust funds in trust for the purpose of
      making the following payments, specifically pledged as security for, and
      dedicated solely to, the benefit of the Holders of the Securities of such
      series, (A) cash in an amount, or (B) in the case of any series of
      Securities the payments on which may only be made in legal coin or
      currency of the United States, U.S. Government Obligations, maturing as to
      principal and interest at such times and in such amounts as will insure
      the availability of cash, or (C) a combination


                                      -58-
<PAGE>
      thereof, sufficient, in the opinion of a nationally recognized firm of
      independent public accountants expressed in a written certification
      thereof delivered to the Trustee, to pay (i) the principal and interest
      and premium, if any, on all Securities of such series on each date that
      such principal, interest or premium, if any, is due and payable or on any
      Redemption Date established pursuant to clause (2) below, and (ii) any
      mandatory sinking fund payments on the day on which such payments are due
      and payable in accordance with the terms of the Indenture and the
      Securities of such series;

            (2) If the Securities are to be redeemed prior to Stated Maturity
      (other than from mandatory sinking fund payments or analogous payments),
      notice of such redemption shall have been duly given pursuant to this
      Indenture or provision therefor satisfactory to the Trustee shall have
      been made;

            (3) No Event of Default or event which with notice or lapse of time
      or both would become an Event of Default shall have occurred and be
      continuing on the date of such deposit;

            (4) The Partnership has delivered to the Trustee an Opinion of
      Counsel which shall confirm that the Holders of the Securities of such
      series will not recognize income, gain or loss for federal income tax
      purposes as a result of such deposit and covenant defeasance and will be
      subject to federal income tax on the same amount and in the same manner
      and at the same time as would have been the case if such deposit and
      covenant defeasance had not occurred;

            (5) Such covenant defeasance shall not cause the Trustee to have a
      conflicting interest within the meaning of the Trust Indenture Act
      (assuming all Securities are in default within the meaning of such Act);

            (6) Such covenant defeasance shall not result in a breach or
      violation of, or constitute a default under, any other agreement or
      instrument to which the Partnership is a party or by which it is bound;

            (7) Such covenant defeasance shall not result in the trust arising
      from such deposit constituting an investment company within the meaning of
      the Investment Company Act of 1940, as amended, unless such trust shall be
      registered under such Act or exempt from registration thereunder; and

            (8) The Partnership has delivered to the Trustee an Officers'
      Certificate stating that all conditions precedent provided for relating to
      the covenant defeasance contemplated by this provision have been complied
      with.

SECTION 1304. Application by Trustee of Funds Deposited for Payment of
Securities.

      Subject to the provisions of the last paragraph of Section 1003, all
moneys or U.S. Government Obligations deposited with the Trustee pursuant to
Section 1302 or 1303 (and all funds earned on such moneys or U.S. Government
Obligations) shall be held in trust and applied by it to the payment, either
directly or through any Paying Agent (including the Partnership acting as its
own Paying Agent), to the Holders of the particular Securities of such series
for the


                                      -59-
<PAGE>
payment or redemption of which such moneys have been deposited with the Trustee,
of all sums due and to become due thereon for principal and interest; but such
money need not be segregated from other funds except to the extent required by
law. Subject to Sections 1302 and 1303, the Trustee shall promptly pay to the
Partnership upon request any excess moneys held by it at any time.

SECTION 1305. Repayment to Partnership.

      The Trustee and any Paying Agent promptly shall pay or return to the
Partnership upon Partnership Request any money and U.S. Government Obligations
held by them at any time that are not required for the payment of the principal
of and any interest on the Securities of any series for which money or U.S.
Government Obligations have been deposited pursuant to Section 1302 or 1303.

      The provisions of the last paragraph of Section 1003 shall apply to any
money held by the Trustee or any Paying Agent under this Article that remains
unclaimed for two years after the Maturity of any series of Securities for which
money or U.S. Government Obligations have been deposited pursuant to Section
1302 or 1303.

                                  ARTICLE XIV

                           SUBORDINATION OF SECURITIES

SECTION 1401. Securities Subordinated to Senior Debt.

            (1) The Partnership, for itself, its successors and assigns,
      covenants and agrees, and each Holder of Securities, by his acceptance
      thereof, likewise covenants and agrees, that the payment of the principal
      of (and premium, if any), and interest on each and all of the Securities
      is hereby expressly subordinated, to the extent and in the manner
      hereinafter set forth, in right of payment to the prior payment in full of
      all Senior Debt of the Partnership.

            (2) If (A) the Partnership shall default in the payment of any
      principal of, premium, if any, or interest, if any, on any Senior Debt of
      the Partnership when the same becomes due and payable, whether at maturity
      or at a date fixed for prepayment or by declaration of acceleration or
      otherwise, or (B) any other default shall occur with respect to Senior
      Debt of the Partnership and the maturity of such Senior Debt has been
      accelerated or otherwise becomes due in accordance with its terms, then,
      upon written notice of such default to the Partnership and the Trustee by
      the holders of Senior Debt of the Partnership or any trustee therefor,
      unless and until, in either case, the default has been cured or waived or
      has ceased to exist, or, any such acceleration has been rescinded or such
      Senior Debt has been paid in full, no direct or indirect payment (in cash,
      property, securities, by set-off or otherwise) shall be made or agreed to
      be made on account of the principal of, premium, if any, or interest, if
      any, on any of the Securities, or in respect of any redemption,
      retirement, purchase or other acquisition of any of the Securities other
      than those made in capital stock of the Partnership (or cash in lieu of
      fractional shares thereof).


                                      -60-
<PAGE>
            (3) If any default occurs under the Senior Debt of the Partnership,
      pursuant to which the maturity thereof may be accelerated immediately
      without further notice (except such notice as may be required to effect
      such acceleration) or at the expiration of any applicable grace periods (a
      "Senior Nonmonetary Default"), then, upon the receipt by the Partnership
      and the Trustee of written notice thereof (a "Payment Blockage Notice")
      from or on behalf of holders of such Senior Debt of the Partnership
      specifying an election to prohibit such payment and other action by the
      Partnership in accordance with the following provisions of this paragraph
      (3), the Partnership may not make any payment or take any other action
      that would be prohibited by paragraph (2) of this Section 1401 during the
      period (the "Payment Blockage Period") commencing on the date of receipt
      of such Payment Blockage Notice and ending on the earlier of (A) the date,
      if any, on which the holders of such Senior Debt or their representative
      notifies the Trustee that such Senior Nonmonetary Default is cured or
      waived or ceases to exist or the Senior Debt to which such Senior
      Nonmonetary Default relates is discharged or (B) the 179th day after the
      date of receipt of such Payment Blockage Notice. Notwithstanding the
      provisions described in the immediately preceding sentence, the
      Partnership may resume payments on the Securities following such Payment
      Blockage Period.

SECTION 1402. Distribution on Dissolution, Liquidation and Reorganization;
Subrogation of Securities.

      Upon any distribution of assets of the Partnership upon any dissolution,
winding up, liquidation or reorganization of the Partnership, whether in
bankruptcy, insolvency, reorganization or receivership proceedings or upon an
assignment for the benefit of creditors or any other marshalling of the assets
and liabilities of the Partnership or otherwise (subject to the power of a court
of competent jurisdiction to make other equitable provision reflecting the
rights conferred in this Indenture upon the Senior Debt of the Partnership and
the holders thereof with respect to the Securities and the Holders thereof by a
lawful plan or reorganization under applicable bankruptcy law),

            (1) the holders of all Senior Debt of the Partnership shall be
      entitled to receive payment in full of the principal thereof, premium, if
      any, interest, and any interest thereon, due thereon before the Holders of
      the Securities are entitled to receive any payment upon the principal,
      premium, interest of or on the Securities or interest on overdue amounts
      thereof; and

            (2) any payment or distribution of assets of the Partnership of any
      kind or character, whether in cash, property or securities, to which the
      Holders of the Securities or the Trustee (on behalf of the Holders) would
      be entitled except for the provisions of this Article XIV shall be paid by
      the liquidating trustee or agent or other person making such payment or
      distribution, whether a trustee in bankruptcy, a receiver or liquidating
      trustee or otherwise, directly to the holders of Senior Debt of the
      Partnership or their representative or representatives or to the trustee
      or trustees under any indenture under which any instruments evidencing any
      of such Senior Debt may have been issued, ratably according to the
      aggregate amounts remaining unpaid on account of the principal of,
      premium, if any, interest, and any interest thereon, on the Senior Debt of
      the Partnership held or represented by each, to the extent necessary to
      make payment in full of all Senior


                                      -61-
<PAGE>
      Debt of the Partnership remaining unpaid, after giving effect to any
      concurrent payment or distribution to the holders of such Senior Debt; and

            (3) in the event that, notwithstanding the foregoing, any payment or
      distribution of assets of the Partnership of any kind or character,
      whether in cash, property or securities, shall be received by the Trustee
      (on behalf of the Holders) or the Holders of the Securities before all
      Senior Debt of the Partnership is paid in full, such payment or
      distribution shall be paid over to the holders of such Senior Debt or
      their representative or representatives or to the trustee or trustees
      under any indenture under which any instruments evidencing any of such
      Senior Debt may have been issued, ratably as aforesaid, for application to
      the payment of all Senior Debt remaining unpaid until all such Senior Debt
      shall have been paid in full, after giving effect to any concurrent
      payment or distribution to the holders of such Senior Debt.

      Subject to the payment in full of all Senior Debt of the Partnership, the
Holders of the Securities shall be subrogated to the rights of the holders of
such Senior Debt to receive payments or distributions of cash, property or
securities of the Partnership applicable to Senior Debt of the Partnership until
the principal, premium, interest, and any interest thereon, of or on the
Securities shall be paid in full and no such payments or distributions to the
Holders of the Securities of cash, property or securities otherwise
distributable to the Senior Debt of the Partnership shall, as between the
Partnership, its creditors other than the holders of Senior Debt of the
Partnership, and the Holders of the Securities, be deemed to be a payment by the
Partnership to or on account of the Securities. It is understood that the
provisions of this Article XIV 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 Debt of the Partnership, on the other hand. Nothing
contained in this Article XIV or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as between the Partnership, its
creditors other than the holders of Senior Debt of the Partnership, and the
Holders of the Securities, the obligation of the Partnership, which is
unconditional and absolute, to pay to the Holders of the Securities the
principal, premium, interest, and any interest thereon, of or on the Securities
as and when the same shall become due and payable in accordance with their
terms, or to affect the relative rights of the Holders of the Securities and
creditors of the Partnership other than the holders of Senior Debt of the
Partnership, nor shall anything herein or in the Securities 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 rights, if
any, under this Article XIV of the holders of such Senior Debt in respect of
cash, property or securities of the Partnership received upon the exercise of
any such remedy. Upon any payment or distribution of assets of the Partnership
referred to in this Article XIV, the Trustee shall be entitled to conclusively
rely upon a certificate of the liquidating trustee or agent or other person
making any distribution to the Trustee for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of Senior Debt
of the Partnership and other indebtedness of the Partnership, the amount thereof
or payable thereon, the amount or amounts paid or distributed thereon, and all
other facts pertinent thereto or to this Article XIV.

      The Trustee, however, shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt of the Partnership. The Trustee shall not be liable to
any such holder if it shall pay over or distribute to or on behalf of Holders of
Securities or the Partnership moneys or assets to


                                      -62-
<PAGE>
which any holder of Senior Debt of the Partnership shall be entitled by virtue
of this Article XIV. The rights and claims of the Trustee under Section 607
shall not be subject to the provisions of this Article XIV.

      If the Trustee or any Holder of Securities does not file a proper claim or
proof of debt in the form required in any proceeding referred to above prior to
30 days before the expiration of the time to file such claim in such proceeding,
then the holder of any Senior Debt of the Partnership is hereby authorized, and
has the right, to file an appropriate claim or claims for or on behalf of such
Holder of Securities.

SECTION 1403. Payments on Securities Permitted.

      Nothing contained in this Indenture or in any of the Securities shall (1)
affect the obligation of the Partnership to make, or prevent the Partnership
from making, at any time except as provided in Sections 1401 and 1402, payments
of principal, premium, interest, and any interest thereon, of or on the
Securities or (2) prevent the application by the Trustee of any moneys deposited
with it hereunder to the payment of or on account of the principal, premium,
interest or other amounts, and any interest thereon, of or on the Securities
unless the Trustee shall have received at its Corporate Trust Office written
notice of any event prohibiting the making of such payment two Business Days (A)
prior to the date fixed for such payment, (B) prior to the execution of an
instrument to satisfy and discharge this Indenture based upon the deposit of
funds under Section 401(1)(b), (C) prior to the execution of an instrument
acknowledging the defeasance of such Securities pursuant to Section 1302 or (D)
prior to any deposit pursuant to clause (1) of Section 1303 with respect to such
Securities.

SECTION 1404. Authorization of Holders of Securities to Trustee to Effect
Subordination.

      Each Holder of Securities by his acceptance thereof, whether upon original
issue or upon transfer or assignment, authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination as provided in this Article XIV and appoints the Trustee his
attorney-in-fact for any and all such purposes.

SECTION 1405. Notices to Trustee.

      The Partnership shall give prompt written notice to a Responsible Officer
of the Trustee located at the Corporate Trust Office of the Trustee of any fact
known to the Partnership which would prevent the making of any payment to or by
the Trustee in respect of the Securities. Notwithstanding the provisions of this
Article XIV or any other provisions of this Indenture, neither the Trustee nor
any Paying Agent (other than the Partnership) shall be charged with knowledge of
the existence of any Senior Debt of the Partnership or of any event which would
prohibit the making of any payment of moneys to or by the Trustee or such Paying
Agent, unless and until the Trustee or such Paying Agent shall have received (in
the case of the Trustee, at its Corporate Trust Office) written notice thereof
from the Partnership or from the holder of any Senior Debt of the Partnership or
from the trustee for or representative of any Senior Debt of the Partnership
together with proof satisfactory to the Trustee of such holding of such Senior
Debt or of the authority of such trustee or representative; provided, however,
that if at least two Business Days prior to the date upon which by the terms
hereof any such moneys may become payable for


                                      -63-
<PAGE>
any purpose (including, without limitation, the payment of the principal,
premium, interest, of or on any Security, or any interest thereon) or the date
on which the Trustee shall execute an instrument acknowledging satisfaction and
discharge of this Indenture or the defeasance of Securities pursuant to Section
1302 or the date on which a deposit pursuant to clause (1) of Section 1303 is
made, the Trustee shall not have received with respect to such moneys or the
moneys deposited with it as a condition to such satisfaction and discharge or
defeasance the notice provided for in this Section 1405, then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such moneys and to apply the same to the purpose for which
they were received, and shall not be affected by any notice to the contrary,
which may be received by it on or after such two Business Days prior to such
date. The Trustee shall be entitled to conclusively rely on the delivery to it
of a written notice by a person representing himself to be a holder of Senior
Debt of the Partnership (or a trustee or representative on behalf of such
holder) to establish that such a notice has been given by a holder of Senior
Debt of the Partnership or a trustee or representative on behalf of any such
holder. 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 Debt of the Partnership to participate in any payment or distribution
pursuant to this Article XIV, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Debt of the Partnership 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 XIV 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 1406. Trustee as Holder of Senior Debt.

      The Trustee shall be entitled to all the rights set forth in this Article
XIV in respect of any Senior Debt of the Partnership at any time held by it to
the same extent as any other holder of Senior Debt of the Partnership and
nothing in this Indenture shall be construed to deprive the Trustee of any of
its rights as such holder.

SECTION 1407. Modification of Terms of Senior Debt.

      Any renewal or extension of the time of payment of any Senior Debt of the
Partnership or the exercise by the holders of Senior Debt of the Partnership of
any of their rights under any instrument creating or evidencing such Senior
Debt, including without limitation the waiver of default thereunder, may be made
or done all without notice to or assent from Holders of the Securities or the
Trustee.

      No compromise, alteration, amendment, modification, extension, renewal or
other change of, or waiver, consent or other action in respect of, any liability
or obligation under or in respect of, or of any of the terms, covenants or
conditions of any indenture or other instrument under which any Senior Debt of
the Partnership is outstanding or of such Senior Debt, regardless of whether
such release is in accordance with the provisions of any applicable document,
shall in any way alter or affect any of the provisions of this Article XIV or of
the Securities relating to the subordination thereof.

      This instrument may be executed with counterpart signature pages or 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.
