by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of


                                       12
<Page>

Holders of Securities of such series voting in favor thereof, either in person
or by proxies duly appointed in writing, at any meeting of Holders of Securities

and, where it is hereby expressly required, to the Partnership. Such instrument
or instruments and any such record (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments or so voting at any such meeting. Proof
of execution of any such instrument or of a writing appointing any such agent,
or of the holding by any Person of a Security, shall be sufficient for any
purpose of this Indenture and conclusive in favor of the Trustee and the
Partnership and any agent of the Trustee or the Partnership, if made in the
manner provided in this Section. The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1506.

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

            (c) The ownership of Registered Securities shall be proved by the
Security Register. As to any matter relating to beneficial ownership interests
in any Global Security, the appropriate depository's records shall be
dispositive for purposes of this Indenture.

            (d) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depository, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory. The Trustee and the Partnership may assume that such ownership
of any Bearer Security continues until (1) another certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is produced,
or (2) such Bearer Security is produced to the Trustee by some other Person, or
(3) such Bearer Security is surrendered in exchange for a Registered Security,
or (4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

            (e) If the Partnership shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Partnership may, at its option, in or pursuant to a
Board Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Partnership shall have no obligation to do
so. Notwithstanding TIA Section 316(c), such record date shall be the record
date specified in or pursuant to such Board Resolution, which shall be a date
not earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities shall be computed as of such record date;
PROVIDED that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than eleven months after the
record date.

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

expressly provided) if in writing and mailed, first-class postage prepaid, to
each such 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 of Registered Securities 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 of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

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

      Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 301, where this Indenture provides
for notice to Holders of Bearer Securities of any event, such notice shall be
sufficiently given if published in an Authorized Newspaper in The City of New
York and in such other city or cities as may be specified in such Securities on
a Business Day, such publication to be not later than the latest date, if any,
and not earlier than the earliest date, if any, prescribed for the giving of
such notice. Any such notice shall be deemed to have been given on the date of
such publication or, if published more than once, on the date of the first such
publication.

      If by reason of the suspension of publication of any Authorized Newspaper
or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

      Any request, demand, authorization, direction, notice, consent or waiver
required or permitted under this Indenture shall be in the English language,
except that any published notice may be in an official language of the country
of publication.

      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.

      SECTION 107. COUNTERPARTS; EFFECT OF HEADINGS AND TABLE OF CONTENTS. This
Indenture may be executed in any number of counterparts, each of which so
executed shall be deemed to be an original, but all such counterparts shall
together constitute but one and the same Indenture. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

      SECTION 108. SUCCESSORS AND ASSIGNS. All covenants and agreements in this
Indenture by the Partnership shall bind its successors and assigns, whether so
expressed or not.

      SECTION 109. SEVERABILITY CLAUSE. In case any provision in this Indenture
or in any Security or coupon 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 110. BENEFITS OF INDENTURE. Nothing in this Indenture or in the
Securities or coupons, express or implied, shall give to any Person, other than
the parties hereto, any Security Registrar, any Paying Agent, any Authenticating
Agent and their successors hereunder and the Holders any benefit or any legal or
equitable right, remedy or claim under this Indenture.

      SECTION 111. GOVERNING LAW. This Indenture and the Securities and coupons
shall be governed by and construed in accordance with the law of the State of
New York. This Indenture is subject to the provisions of the TIA that are
required to be part of this Indenture and shall, to the extent applicable, be
governed by such provisions.

      SECTION 112. LEGAL HOLIDAYS. In any case where any Interest Payment Date,
Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or
Maturity of any Security or the last date on which a Holder has the right to
exchange a Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or any Security or coupon
other than a provision in the Securities of any series which specifically states
that such provision shall apply in lieu hereof), payment of interest or
principal (and premium or Make-Whole Amount, if any) or exchange of such
security need not be made at such Place of Payment on such date, but (except as
otherwise provided in the supplemental indenture with respect to such Security)
may be made on the next succeeding


                                       16
<Page>

Business Day at such Place of Payment with the same force and effect as if made
on the Interest Payment Date, Redemption Date, Repayment Date or sinking fund
payment date, or at the Stated Maturity or Maturity, or on such last day for
exchange, provided that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date, Repayment
Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be
to the next Business Day.

      SECTION 113. NON-RECOURSE. Notwithstanding anything contained herein to
the contrary, no recourse under or upon any obligation, covenant or agreement
contained in this Indenture, in any Security or coupon appertaining thereto, or
because of any indebtedness evidenced thereby (including, without limitation,
any obligation or indebtedness relating to the principal of, or premium or
Make-Whole Amount, if any, interest or any other amounts due or claimed to be
due, on any security issued hereunder, or for any claim based thereon
or otherwise in respect hereof), shall be had against the Company or any other
past, present or future partner in the Partnership, (ii) any other Person which
owns an interest, directly or indirectly, in any partner of the Partnership or
(iii) any past, present or future stockholder, employee, officer or director, as
such, of the Company or of any successor, either directly or through the
Partnership or the Company or any successor, whether by virtue of any
constitution, statute or rule of law or by the enforcement of any assessment or
penalty or otherwise, all such liability being expressly waived and released by
the acceptance of the Securities by the Holders and as part of the consideration
for the issue of the Securities.

      SECTION 114. CONFLICT WITH TRUST INDENTURE ACT. If any provision hereof
limits, qualifies or conflicts with another provision hereof which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

                         ARTICLE TWO - SECURITIES FORMS

      SECTION 201. FORMS OF SECURITIES. The Registered Securities, if any, of
each series and the Bearer Securities, if any, of each series and related
coupons shall be substantially in the form of EXHIBIT A hereto or in such other
form as shall be established in one or more indentures supplemental hereto or
approved from time to time by or pursuant to a Board Resolution in accordance
with Section 301, shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture or any indenture supplemental hereto, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements placed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto


                                       17

be listed, or to conform to usage.

      Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have Interest coupons attached.

      The definitive Securities and coupons shall be printed, lithographed or
engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or mechanically reproduced on safety paper or

such Securities or coupons, as evidenced by their execution of such Securities
or coupons.

      SECTION 202. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION. Subject to
Section 611, the Trustee's certificate of authentication shall be in

                                           as Trustee


Dated: ______________                      By:__________________________________
                                                     Authorized Signatory

      SECTION 203. SECURITIES ISSUABLE IN GLOBAL FORM. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security or other
notation in the books and records of the Trustee to reflect the amount, or any
increase or decrease in the amount, or changes in the rights of Holders thereof,
of Outstanding Securities represented thereby shall be made by the Trustee in
accordance with the Trustee's customary practice or otherwise in such manner or
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered to the Trustee pursuant to Section 303 or 304. Subject to the

been, or simultaneously is, delivered, any instructions by the

<Page>

Company with respect to endorsement or delivery or redelivery of a Global
Security shall be in writing but need not comply with Section 102 and need not
be accompanied by an Opinion of Counsel.

      The provisions of the last sentence of Section 303 shall apply to any
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 written instructions (which need not comply with Section
102 and need not be accompanied by an Opinion of Counsel) with regard to the
reduction in the principal amount of Securities represented thereby, together
with the written statement contemplated by the last sentence of Section 303.

      Notwithstanding the provisions of Section 307, unless otherwise specified
as contemplated by Section 301, payment of principal of and any premium or
Make-Whole Amount, if any, and interest on any Global Security in permanent
global form shall be made to the registered Holder thereof.

      Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Partnership, the Trustee and any agent of the
Partnership and the Trustee shall treat as the Holder of such principal amount
of Outstanding Securities represented by a permanent Global Security (i) in the
case of a permanent Global Security in registered form, the Holder of such
permanent Global Security in registered form, or (ii) in the case of a permanent
Global Security in bearer form, Euroclear or CEDEL.

      Any Global Security authenticated and delivered hereunder shall bear a
legend in substantially the following form:

            "This Security is a Global Security within the meaning
            set forth in the Indenture hereinafter referred to and
            is registered in the name of a Depository or a nominee
            of a Depository. This Security is exchangeable for
            Securities registered in the name of a person other than
            the Depository or its nominee only in the limited
            circumstances described in the Indenture, and may not be
            transferred except as a whole by the Depository to a
            nominee of the Depository or by a nominee of the
            Depository to the Depository or another nominee of the
            Depository or by the Depository or its nominee to a
            successor Depository or its nominee."

      the series are to be issuable initially in temporary global form and
      whether any Securities of the series are to be issuable in permanent
      global form with or without coupons and, if so, whether beneficial owners
      of interests in any such permanent global Security may exchange such

<Page>

                  (20) If the Securities of such series are to be issuable in
      definitive form (whether upon original issue or upon exchange of a
      temporary Security of such series) only upon receipt of certain
      certificates or other documents or satisfaction of other conditions, then
      the form and/or terms of such certificates, documents or conditions; and

                  (21) Any other terms of the series (which terms shall not be
      inconsistent with the provisions of this Indenture).

      All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate 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 issuances of additional Securities of such series.

      If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant
Secretary of the Company, as general partner of the Partnership, and delivered
to the Trustee at or prior to the delivery of the Officers Certificate setting
forth the terms of the Securities of such series.

      SECTION 302. DENOMINATIONS. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions with respect to the Securities of any series, the
Securities of such series, other than Global Securities (which may be of any
denomination), shall be issuable in denominations of $1,000 and any integral
multiple thereof.

      SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Company, as general partner of the Partnership, by its President, any
Executive Vice President or Senior Vice President or its Chief Financial
Officer, under its corporate seal reproduced thereon, and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities and coupons may be manual or facsimile signatures of
the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

      Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company, as general
partner of the Partnership, shall bind the Partnership, notwithstanding that
such individuals or any of them have ceased to


                                       23
<Page>

hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

      At any time and from time to time after the execution and delivery of this
Indenture, the Partnership may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Partnership to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; PROVIDED, HOWEVER, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and PROVIDED FURTHER
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to Euroclear or CEDEL, as the case
may be, in the form set forth in Exhibit B-1 to this Indenture or such other
certificate as may be specified with respect to any series of Securities
pursuant to Section 301, dated no earlier than 15 days prior to the earlier of
the date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. If any
Security shall be represented by a permanent global Bearer Security, then, for
purposes of this Section and Section 304, the notation of a beneficial owner's
interest therein upon original issuance of such Security or upon exchange of a
portion of a temporary Global Security shall be deemed to be delivered in
connection with the original issuance of such beneficial owner's interest in
such permanent Global Security. Except as permitted by Section 306, the Trustee
shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and canceled.

      If all the Securities of any series are not to be issued at one time and
if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee
for the issuance of such Securities and determining the terms of particular
Securities of such series, such as interest rate or formula, maturity date, date
of issuance and date from which interest shall accrue. 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 TIA Section 315(a) through 315(d)) shall be fully protected in
relying upon,

            (i) an Opinion of Counsel stating that

                  (a) the form or forms of such Securities and any coupons have
            been established in conformity with the provisions of this
            Indenture;

                  (b) the terms of such Securities and any coupons have been
            established in conformity with the provisions of this Indenture; and

                  (c) such Securities, together with any coupons appertaining
            thereto, when completed by appropriate insertions and executed and
            delivered by the Partnership to the Trustee for authentication in
            accordance with this Indenture, authenticated and delivered by the
            Trustee in accordance with this Indenture and issued by the
            Partnership in the manner and subject to any conditions specified in
            such Opinion of Counsel, will constitute legal, valid and legally
            binding obligations of the Partnership, enforceable in accordance
            with their terms, subject to applicable bankruptcy, insolvency,
            fraudulent transfer, reorganization and other similar laws of
            general applicability relating to or affecting the enforcement of
            creditors' rights generally and to general equitable principles; and

            (ii) an Officers' Certificate stating that all conditions precedent
      provided for in this Indenture relating to the issuance of the Securities
      have been complied with and that, to the best of the knowledge of the
      signers of such certificate, that no Event of Default with respect to any
      of the Securities shall have occurred and be continuing.

If such form 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,
obligations 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 the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each Security of such series, but such order, opinion
and certificates, with appropriate modifications to cover such future issuances,
shall be delivered at or before the time of issuance of the first Security of
such series.

      Each Registered Security shall be dated the date of its authentication and
each Bearer Security shall be dated as of the date specified as contemplated by
Section 301.

      No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global 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 together with a written statement (which need not comply with


                                       25
<Page>

Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Partnership, 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.

      (a) Pending the preparation of definitive Securities of any series, the
Partnership may execute, and upon Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, m any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they are issued, in
registered form, or, if authorized, in bearer form with one or more coupons or
without coupons, and with such appropriate insertions, omissions, substitutions
and other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. In the case of
Securities of any series, such temporary Securities may be in global form.

      Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution), 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 in a Place of Payment
for that series, without charge to the Holder. Upon surrender for cancellation
of any one or more temporary Securities of any series (accompanied by any
non-matured coupons appertaining thereto), the Partnership shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations;
PROVIDED, HOWEVER, that no definitive Bearer Security shall be delivered in
exchange for a temporary Registered Security; and PROVIDED FURTHER that a
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303. 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.

      (b) Unless otherwise provided in or pursuant to a Board Resolution, the
following provisions of this Section 304(b) shall govern the exchange of
temporary Securities other than through the facilities of The Depository Trust
Company. If any such temporary Security is issued in global form, then such
temporary Global Security shall, unless otherwise provided therein, be delivered
to the London office of a depository or common depository (the "Common
Depository"), for the benefit of Euroclear and CEDEL, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).


                                       26
<Page>

      Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Partnership shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Partnership. On or
after the Exchange Date, such temporary Global Security shall be surrendered by
the Common Depository to the Trustee, as the Partnership's agent for such
purpose, to be exchanged, in whole or from time to time in part, for definitive
Securities without charge, and the Trustee shall authenticate and deliver, in
exchange for each portion of such temporary Global Security, an equal aggregate
principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such temporary Global Security
to be exchanged. The definitive Securities to be delivered in exchange for any
such temporary Global Security shall be in bearer form, registered form,
permanent global bearer form or permanent global registered form, or any
combination thereof, as specified as contemplated by Section 301, and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof; PROVIDED, HOWEVER, that, unless otherwise specified in such temporary
Global Security, upon such presentation by the Common Depository, such temporary
Global Security is accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by Euroclear as to the portion of such temporary
Global Security held for its account then to be exchanged and a certificate
dated the Exchange Date or a subsequent date and signed by CEDEL as to the
portion of such temporary Global Security held for its account then to be
exchanged, each in the form set forth in Exhibit B-2 to this Indenture or in
such other form as may be established pursuant to Section 301; and PROVIDED
FURTHER that definitive Bearer Securities shall be delivered in exchange for a
portion of a temporary Global Security only in compliance with the requirements
of Section 303.

      Unless otherwise specified in such temporary Global Security, the interest
of a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
CEDEL, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or CEDEL, as the case may be, a certificate in the form set forth
in Exhibit B-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary Global
Security shall be delivered only outside the United States.

      Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities


                                       27
<Page>

of the same series and of like tenor authenticated and delivered hereunder,
except that, unless otherwise specified as contemplated by Section 301, interest
payable on a temporary Global Security on an Interest Payment Date for
Securities of such series occurring prior to the applicable Exchange Date shall
be payable to Euroclear and CEDEL on such Interest Payment Date upon delivery by
Euroclear and CEDEL to the Trustee of a certificate or certificates in the form
set forth in Exhibit B-2 to this Indenture (or in such other forms as may be
established pursuant to Section 301), for credit without further interest on or
after such Interest Payment Date to the respective accounts of Persons who are
the beneficial owners of such temporary Global Security on such Interest Payment
Date and who have each delivered to Euroclear or CEDEL, as the case may be, a
certificate dated no earlier than 15 days prior to the Interest Payment Date
occurring prior to such Exchange Date in the form set forth as Exhibit B-1 to
this Indenture (or in such other forms as may be established pursuant to Section
301). Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section 304(b) and of the
third paragraph of Section 303 of this Indenture and the interests of the
Persons who are the beneficial owners of the temporary Global Security with
respect to which such certification was made will be exchanged for definitive
Securities of the same series and of like tenor on the Exchange Date or the date
of certification if such date occurs after the Exchange Date, without further
act or deed by such beneficial owners. Except as otherwise provided in this
paragraph, no payments of principal or interest owing with respect to a
beneficial interest in a temporary Global Security will be made unless and until
such interest in such temporary Global Security shall have been exchanged for an
interest in a definitive Security. Any interest so received by Euroclear and
CEDEL and not paid as herein provided shall be returned to the Trustee prior to
the expiration of two years after such Interest Payment Date in order to be
repaid to the Partnership pursuant to Section 103.

      SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. The
Partnership shall cause to be kept at the Corporate Trust Office of the Trustee
or in any office or agency of the Partnership in a Place of Payment a register
for each series of Securities (the registers maintained in such office or in any
such office or agency of the Partnership in a Place of Payment being herein
sometimes referred to collectively as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Partnership shall
provide for the registration of Registered Securities and of transfers of
Registered Securities. The Security Register shall be in written form or any
other form capable of being converted into written form within a reasonable
time. The Trustee, at its Corporate Trust Office, is hereby initially appointed
"Security Registrar" for the purpose of registering Registered Securities and
transfers of Registered Securities on such Security Register as herein provided.
In the event that the Trustee shall cease to be Security Registrar, it shall
have the right to examine the Security Register at all reasonable times.

      Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Partnership in a Place of Payment for that series, the
Partnership shall execute, and the Trustee shall authenticate and


                                       28
<Page>

deliver, in the name of the designated transferee or transferees, one or more
new Registered Securities of the same series, of any authorized denominations
and of a like aggregate principal amount, bearing a number not contemporaneously
outstanding, and containing identical terms and provisions.

      Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Partnership shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive. Unless otherwise specified with
respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

      If (but only if) permitted by the applicable Board Resolution and (subject
to Section 303) set forth in the applicable Officers' Certificate or in any
indenture supplemental hereto delivered as contemplated by Section 301, then at
the option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Partnership in an amount equal to the face amount of such missing coupon
or coupons, or the surrender of such missing coupon or coupons may be waived by
the Partnership and the Trustee if there is furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security shall surrender to any
Paying Agent any such missing coupon in respect of which such a payment shall
have been made, such Holder shall be entitled to receive the amount of such
payment; PROVIDED, HOWEVER, that, except as otherwise provided in Section 1002,
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange


                                       29
<Page>

for such Bearer Security, but will be payable only to the Holder of such coupon
when due in accordance with the provisions of this Indenture. 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.

      Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security shall be exchangeable
only as provided in this paragraph. If the depository for any permanent Global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
Global Security expressly permit such Global Security to be exchanged in whole
or in part for definitive Securities, a Global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such Global Security selected or approved by the
Partnership or to a nominee of such successor to DTC. If at any time DTC
notifies the Partnership that it is unwilling or unable to continue as
depository for the applicable Global Security or Securities or if at any time
DTC ceases to be a clearing agency registered under the Securities Exchange Act
of 1934 if so required by applicable law or regulation, the Partnership shall
appoint a successor depository with respect to such Global Security or
Securities. If (x) a successor depository for such Global Security or Securities
is not appointed by the Partnership within 90 days after the Partnership
receives such notice or becomes aware of such unwillingness, inability or
ineligibility, (y) an Event of Default has occurred and is continuing and the
beneficial owners representing a majority in principal amount of the applicable
series of Securities represented by such Global Security or Securities advise
DTC to cease acting as depository for such Global Security or Securities or (z)
the Partnership, in its sole discretion, determines at any time that all
Outstanding Securities (but not less than all) of any series issued or issuable
in the form of one or more Global Securities shall no longer be represented by
such Global Security or Securities, then the Partnership shall execute, and the
Trustee shall authenticate and deliver definitive Securities of like series,
rank, tenor and terms in definitive form in an aggregate principal amount equal
to the principal amount of such Global Security or Securities. If any beneficial
owner of an interest in a permanent Global Security is otherwise entitled to
exchange such interest for Securities of such series and of like tenor and
principal amount of another authorized form and denomination, as specified as
contemplated by Section 301 and provided that any applicable notice provided in
the permanent Global Security shall have been given, then without unnecessary
delay but in any event not later than the earliest date on which such interest
may be so exchanged, the Partnership shall execute, and the Trustee shall
authenticate and deliver definitive Securities in aggregate principal amount
equal to the principal amount of such beneficial owner's interest in such
permanent Global Security. On or after the earliest date on which such interests
may be so exchanged, such permanent Global Security shall be surrendered for
exchange by DTC or such other depository as shall be specified in the Company
Order with respect thereto to the Trustee, as the Partnership's agent for such
purpose; PROVIDED, HOWEVER, that no such exchanges may occur during a period
beginning at the opening of business 15 days before any selection of Securities
to be redeemed and ending on the relevant Redemption Date if the Security for
which exchange is requested may be among those selected for redemption; and
PROVIDED FURTHER that no Bearer Security


                                       30
<Page>

delivered in exchange for a portion of a permanent Global Security shall be
mailed or otherwise delivered to any location in the United States. If a
Registered Security is issued in exchange for any portion of a permanent Global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, interest or Defaulted Interest,
as the case may be, will not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment, as the case may be, only to the Person to whom interest in respect of
such portion of such permanent Global Security is payable in accordance with the
provisions of this Indenture.

      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 Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Partnership
or the Security Registrar) 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, 906, 1107 or 1305 not involving any
transfer.

      The Partnership or the Trustee, as applicable, shall not be required (i)
to issue, register the transfer of or exchange any Security if such Security may
be among those selected for redemption during a period beginning at the opening
of business 15 days before selection of the Securities to be redeemed under
Section 1103 and ending at the close of business on (A) if such Securities are
issuable only as Registered Securities, the day of the mailing of the relevant
notice of redemption and (B) if such Securities are issuable as Bearer
Securities, the day of the first publication of the relevant notice of
redemption or, if such Securities are also issuable as Registered Securities and
there is no publication, the mailing of the relevant notice of redemption, or
(ii) to register the transfer of or exchange any Registered Security so selected
for redemption in whole or in part, except, in the case of any Registered
Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security so selected for redemption except that
such a Bearer Security may be exchanged for a Registered Security of that series
and like tenor, PROVIDED that such Registered Security shall


                                       31
<Page>

be simultaneously surrendered for redemption, or (iv) to issue, register the
transfer of or exchange any Security which has been surrendered for repayment at
the option of the Holder, except the portion, if any, of such Security not to be
so repaid.

      SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Partnership, together with, in proper cases,
such security or indemnity as may be required by the Partnership or the Trustee
to save each of them or 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 principal amount, containing
identical terms and provisions and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
the surrendered Security.

      If there shall be delivered to the Partnership and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon, and (ii) 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 or coupon has
been acquired by a bona fide purchaser, the Partnership shall execute and upon
its request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security to which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not
destroyed, lost or stolen), a new Security of the same series and principal
amount, containing identical terms and provisions and bearing a number not
contemporaneously outstanding, with coupons corresponding to the coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains.

      Notwithstanding the provisions of the previous two paragraphs, in case any
such mutilated, destroyed, lost or stolen Security or coupon has become or is
about to become due and payable, the Partnership in its discretion may, instead
of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; PROVIDED, HOWEVER, that payment of principal of (and premium or
Make-Whole Amount, if any), and any interest on, Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

      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.


                                       32
<Page>

      Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the
Partnership, whether or not the destroyed, lost or stolen Security and its
coupons, if any, or the destroyed, lost or stolen coupon 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 and their coupons, if any, 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 or coupons.

      SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that 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 at the office or agency of the Partnership
maintained for such purpose pursuant to Section 1002; PROVIDED, HOWEVER, that
each installment of interest on any Registered Security may at the Partnership's
option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 308, to the
address of such Person as it appears on the Security Register or (ii) transfer
to an account maintained by the payee located inside the United States.

      Unless otherwise provided as contemplated by Section 301 with respect to
the Securities of any series, payment of interest may be made, in the case of a
Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

      Unless otherwise provided as contemplated by Section 301, every permanent
Global Security will provide that interest, if any, payable on any Interest
Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case may be,
with respect to that portion of such permanent Global Security held for its
account by Cede & Co. or the Common Depository, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent Global Security to the accounts of the beneficial
owners thereof.

      In case a Bearer Security of any series is surrendered in exchange for a
Registered Security of such series after the close of business (at an office or
agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.


                                       33
<Page>

      Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that 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 registered Holder thereof 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 Registered 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 Registered Security of such series
      and the date of the proposed payment (which shall not be less than 20 days
      after such notice is received by the Trustee), and at the same time the
      Partnership shall deposit with the Trustee an amount of money in the
      currency or currencies, currency unit or units or composite currency or
      currencies in which the Securities of such series are payable (except as
      otherwise specified pursuant to Section 301 for the Securities of such
      series) equal to the aggregate amount proposed to be paid in respect of
      such Defaulted Interest or shall make arrangements satisfactory to the
      Trustee for such deposit prior to the date of the proposed payment, such
      money when deposited to be held in trust for the benefit of the Persons
      entitled to such Defaulted Interest as in this clause provided. Thereupon
      the Trustee shall fix a Special Record Date for the payment of such
      Defaulted Interest which shall be not more than 15 days and not less than
      10 days prior to the date of the proposed payment and not less than 10
      days after the receipt by the Trustee of the notice of the proposed
      payment. The Trustee shall promptly notify the 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 Registered 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. The Trustee may, in its discretion, in the name and
      at the expense of the Partnership, cause a similar notice to be published
      at least once in an Authorized Newspaper in each Place of Payment, but
      such publications shall not be a condition precedent to the establishment
      of such Special Record Date. Notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor having been mailed
      as aforesaid, such Defaulted Interest shall be paid to the Persons in
      whose names the Registered 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). In case a Bearer Security of any series is
      surrendered at the office or agency in a Place of Payment for such series
      in exchange for a Registered Security of such series after the close of
      business at such office or agency on any Special Record Date and before
      the


                                       34
<Page>

      opening of business at such office or agency on the related proposed date
      for payment of Defaulted Interest, such Bearer Security shall be
      surrendered without the coupon relating to such proposed date of payment
      and Defaulted Interest will not be payable on such proposed date of
      payment in respect of the Registered Security issued in exchange for such
      Bearer Security, but will be payable only to the Holder of such coupon
      when due in accordance with the provisions of this Indenture.

                  (2) The Partnership may make payment of any Defaulted Interest
      on the Registered Securities of any series in any other lawful manner not
      inconsistent with the requirements of any securities exchange on which
      such Securities may be listed, 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.

      SECTION 308. PERSONS DEEMED OWNERS. Prior to due presentment of a
Registered 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 Registered Security is registered as the owner of such Security for
the purpose of receiving payment of principal of (and premium or Make-Whole
Amount, if any), and (subject to Sections 305 and 307) interest on, such
Registered Security and for all other purposes whatsoever, whether or not such
Registered Security be overdue, and neither the Partnership, the Trustee nor any
agent of the Partnership or the Trustee shall be affected by notice to the
contrary. All such payments so made to any such Person, or upon such Person's
order, shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for money payable upon any such Security.

      Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Partnership, the Trustee and any agent of the Partnership
or the Trustee may treat the Holder of any Bearer Security and the Holder of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be 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 depository shall have any rights under this Indenture with respect
to such Global Security and such depository shall 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.


                                       35
<Page>

None of the Partnership, the Trustee, any Paying Agent or the Security Registrar
will have any responsibility or liability for any aspect of the records relating
to or payments made on account of beneficial ownership interests of a Global
Security or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

      Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Partnership, the Trustee, or any agent of the
Partnership or the Trustee, from giving effect to any written certification,
proxy or other authorization furnished by any depository, as a Holder, with
respect to such Global Security or impair, as between such depository and owners
of beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such Global Security.

      SECTION 309. CANCELLATION. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, 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 any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose 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. If the Partnership shall so acquire any of the Securities, however,
such acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. 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. Canceled
Securities and coupons held by the Trustee shall be destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Partnership,
unless the Trustee is otherwise directed by a Company Order.

      SECTION 310. COMPUTATION OF INTEREST. Except as otherwise specified as
contemplated by Section 301 with respect to Securities of any series, interest
on the Securities of each series shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.

                    ARTICLE FOUR - 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 any
series of Securities specified in such Partnership Request (except as to any
surviving rights of registration of


                                       36
<Page>

transfer or exchange of Securities of such series herein expressly provided
for), and the Trustee, upon receipt of a Company Order, and at the expense of
the Partnership, shall execute instruments in form and substance satisfactory to
the Trustee and the Partnership acknowledging satisfaction and discharge of this
Indenture as to such series when

                  (1) either

                  (A) all Securities of such series theretofore authenticated
            and delivered and all coupons, if any, appertaining thereto (other
            than (i) coupons appertaining to Bearer Securities surrendered for
            exchange for Registered Securities and maturing after such exchange,
            whose surrender is not required or has been waived as provided in
            Section 305, (ii) Securities and coupons of such series which have
            been destroyed, lost or stolen and which have been replaced or paid
            as provided in Section 306, (iii) coupons appertaining to Securities
            called for redemption and maturing after the relevant Redemption
            Date, whose surrender has been waived as provided in Section 1106,
            and (iv) Securities and coupons of such series 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 discharged from such trust, as provided in Section 1003) have
            been delivered to the Trustee for cancellation; or

                  (B) all Securities of such series and, in the case of (i) or
            (ii) below, any coupons appertaining thereto not theretofore
            delivered to the Trustee for cancellation

                        (i) have become due and payable, or

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

                        (iii) if redeemable at the option of the Partnership,
                  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 the purpose an amount in the currency or
            currencies, currency unit or units or composite currency or
            currencies in which the Securities of such series are payable,
            sufficient to pay and discharge the entire indebtedness on such
            Securities and such coupons not theretofore delivered to the Trustee
            for cancellation, for principal (and premium or Make-Whole Amount,
            if any) and interest to the date of such deposit (in the case of
            Securities which have become


                                       37
<Page>

            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; 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 as to such series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Partnership to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Partnership to any Authenticating Agent
under Section 611 and, if money shall have been deposited with and held by the
Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations
of the Trustee under Section 402 and the last paragraph of Section 1003 shall
survive.

      SECTION 402. APPLICATION OF TRUST FUNDS. 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, the coupons 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 premium or Make-Whole Amount, if any), and any
interest for whose payment such money has been deposited with or received by the
Trustee, but such money need not be segregated from other funds except to the
extent required by law.

                             ARTICLE FIVE - REMEDIES

      SECTION 501. EVENTS OF DEFAULT. "Event of Default," wherever used herein
with respect to any particular series of Securities, means any one of the
following events (whatever the reason for such Event of Default and whether or
not 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 on any Security of
      such series when such interest becomes due and payable that continues for
      a period of 30 days; or

                  (2) default in the payment of the principal of (or Make-Whole
      Amount, if any, on) any Security of such series when due and payable; or


                                       38
<Page>

                  (3) default in the deposit of any sinking fund payment, when
      and as due by the terms of any Security of that series; or

                  (4) default in the performance, or breach, of any covenant or
      warranty of the Partnership in this Indenture with respect to any Security
      of such series (other than a covenant or warranty a default in whose
      performance or whose breach is elsewhere in this Section specifically
      dealt with), 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

                  (5) a default under any bond, debenture, note or other
      evidence of indebtedness for money borrowed (except mortgage indebtedness)
      by the Partnership or any of its Subsidiaries in an aggregate principal
      amount in excess of $25,000,000 or under any indenture or instrument under
      which there may be issued or by which there may be secured or evidenced
      any indebtedness for money borrowed (except mortgage indebtedness) by the
      Partnership or any of its Subsidiaries in an aggregate principal amount in
      excess of $25,000,000, whether such indebtedness exists on the date of
      such Indenture or shall thereafter be created, which default shall have
      resulted in such indebtedness becoming or being declared due and payable
      prior to the date on which it would otherwise have become due and payable
      or such obligations being accelerated, without such acceleration having
      been rescinded or annulled, within a period of 10 days after there shall
      have 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 10% in principal amount of the Outstanding Securities of that series
      a written notice specifying such default and requiring the Partnership to
      cause such indebtedness to be discharged or cause such acceleration to be
      rescinded or annulled and stating that such notice is a "Notice of
      Default" hereunder; or

                  (6) the Partnership or any Significant Subsidiary pursuant to
      or within the meaning of any Bankruptcy Law:

                        (A) commences a voluntary case,

                        (B) consents to the entry of an 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


                                       39
<Page>

                        (D) makes a general assignment for the benefit of its
            creditors; or

                  (7) a court of competent jurisdiction enters an order or
      decree under any Bankruptcy Law that:

                        (A) is for relief against the Partnership or any
            Significant Subsidiary in an involuntary case,

                        (B) appoints a Custodian of the Partnership or any
            Significant Subsidiary or for all or substantially all of either of
            its property, or

                        (C) orders the liquidation of the Company or any
            Significant Subsidiary, and the order or decree remains unstayed and
            in effect for 90 days; or

                  (8) any other Event of Default provided with respect to
      Securities of that series.

As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. Code
or any similar Federal or state law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

      SECTION 502. ACCELERATION OF MATURITY: RESCISSION AND ANNULMENT. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and 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 (or, if Securities of
that Series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal as may be specified in the terms thereof) of all 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 the Holders), and
upon any such declaration such principal or specified portion thereof shall
become immediately due and payable.

      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 of acceleration and its
consequences if:

                  (1) the Partnership has paid or deposited with the Trustee a
      sum sufficient to pay in the currency, currency unit or composite currency
      in which the


                                       40
<Page>

      Securities of such series are payable (except as otherwise specified
      pursuant to Section 301 for the Securities of such series):

                        (A) all overdue installments of interest on all
            Outstanding Securities of that series and any related coupons,

                        (B) the principal of (and premium or Make-Whole Amount,
            if any, on) any Outstanding Securities of that series which have
            become due otherwise than by such declaration of acceleration and
            interest thereon at the rate or rates borne by or provided for in
            such Securities,

                        (C) to the extent that payment of such interest is
            lawful, interest upon overdue installments of interest at the rate
            or rates borne by or provided for 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

                  (2) all Events of Default with respect to Securities of that
      series, other than the nonpayment of the principal of (or premium or
      Make-Whole Amount, if any) or interest on 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 installment of
      interest on any Security of any series and any related coupon when such
      interest becomes due and payable and such default continues for a period
      of 30 days, or

                  (2) default is made in the payment of the principal of (or
      premium or Make-Whole Amount, if any, on) any Security of any series at
      its Maturity,

then the Partnership will, upon demand of the Trustee, pay to the Trustee, for
the benefit of the Holders of such Securities of such series and coupons, the
whole amount then due and payable on such Securities and coupons for principal
(and premium or Make-Whole Amount, if any) and interest, with interest upon any
overdue principal (and premium or Make-Whole Amount, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon any overdue
installments of interest at the rate or rates borne by or provided for in such
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs


                                       41
<Page>

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, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Partnership or any other obligor upon such Securities of such series
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 of such series, wherever situated.

      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 and any
related coupons 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 the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Partnership or any other obligor upon the Securities or the property of the
Partnership or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities of any series shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the
Partnership for the payment of overdue principal, premium or Make-Whole Amount,
if any, or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

                        (i) to file and prove a claim for the whole amount, or
      such lesser amount as may be provided for in the Securities of such
      series, of principal (and premium or Make-Whole Amount, if any) and
      interest owing and unpaid in respect of the Securities and to file such
      other papers or documents as may be necessary or advisable in order to
      have the claims of the Trustee (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel) and of the Holders allowed in such judicial
      proceeding, and

                        (ii) 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 of Securities of such series and coupons 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


                                       42
<Page>

Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee and any predecessor Trustee, their
agents and counsel, and any other amounts due the Trustee or any predecessor
Trustee under Section 606.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or coupon in any such proceeding.

      In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities, and it shall not be necessary to make any Holders of the
Securities parties to any such proceedings.

      SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES
OR COUPONS. All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons 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 and
coupons in respect of which such judgment has been recovered.

      SECTION 506. APPLICATION OF MONEY COLLECTED. Any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium or Make-Whole Amount, if any) or
interest, upon presentation of the Securities or coupons, or both, as the case
may be, 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 and any
      predecessor Trustee under Section 606;

            SECOND: To the payment of the amounts then due and unpaid upon the
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, 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 aggregate amounts due and payable on such
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, respectively; and

            THIRD: To the payment of the remainder, if any, to the Partnership.

      SECTION 507. LIMITATION ON SUITS. No Holder of any Security of any series
or any related coupon 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 to the Trustee
      indemnity reasonably satisfactory to the Trustee against the costs,
      expenses and liabilities to be incurred in compliance with such request;

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

                  (5) no direction inconsistent with such written request has
      been given to the Trustee during such 60-day period by the Holders of a
      majority in principal amount of the Outstanding Securities 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 such
Holders.

      SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
OR MAKE-WHOLE AMOUNT, IF ANY, AND INTEREST. Notwithstanding any other provision
in this Indenture, the Holder of any Security or coupon shall have the right
which is absolute and unconditional to receive payment of the principal of (and
premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307)
interest on such Security or payment of such coupon on the respective due dates
expressed in such Security or coupon (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 of a Security or coupon 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


                                       44
<Page>

determined adversely to the Trustee or to such Holder, then and in every such
case, the Partnership, the Trustee and the Holders of Securities and coupons
shall, subject to any determination in such proceeding, be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

      SECTION 510. RIGHTS AND REMEDIES CUMULATIVE. Except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Securities or coupons in the last paragraph of Section 306, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders of
Securities or coupons is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or
employment- of any -right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or remedy.

      SECTION 511. DELAY OR OMISSION NOT WAIVER. No delay or omission of the
Trustee or of any Holder of any Security or coupon 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 of Securities or coupons, as the
case may be.

      SECTION 512. CONTROL BY HOLDERS OF SECURITIES. The Holders of not less
than a majority in 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 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) the Trustee need not take any action which might involve
      it in personal liability or be unduly prejudicial to the Holders of
      Securities of such series not joining therein.

      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Holders.


                                       45

      SECTION 513. WAIVER OF PAST DEFAULTS. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series and any related
coupons waive any past default hereunder with respect to such series and its
consequences, except a default

                  (1) in the payment of the principal of (or premium or
      Make-Whole Amount, if any) or interest on any Security of such series or
      any related coupons, or

                  (2) in respect of a covenant or provision hereof which under
      Article Nine cannot be modified or amended without the consent of the
      Holder of each Outstanding Security 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 Event of Default or impair any right consequent thereon.

      SECTION 514. 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.

      SECTION 515. UNDERTAKING FOR COSTS. All parties to this Indenture agree,
and each Holder of any Security by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, 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 or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

                            ARTICLE SIX - THE TRUSTEE

      SECTION 601. NOTICE OF DEFAULTS. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
Shall transmit in the manner and to the extent provided in TIA Section 313(c),
notice of such default hereunder known to the Trustee, unless such default shall
have been cured or waived; PROVIDED, HOWEVER, that, except in the case of a
default in the payment of the principal of (or premium or Make-Whole Amount, if
any) or interest on any Security of such series, or in the payment of any
sinking fund installment with respect to the Securities of such series, the
Trustee shall be protected in withholding such notice if and so long as a
Responsible Officer of the Trustee in good faith determine that the withholding
of such notice is in the interests of the Holders of the Securities and coupons
of such series; and PROVIDED FURTHER that in the case of any default or breach
of the character specified in Section 501(4) with respect to the Securities and
coupons of such series, no such notice to Holders shall be given until at least
60 days after the occurrence thereof. For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to the Securities of such series.

      SECTION 602. CERTAIN RIGHTS OF TRUSTEE. Subject to the provisions of TIA
Section 315(a) through 315(d):

                  (1) the Trustee may rely 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, coupon 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 or direction of the Partnership mentioned
      herein shall be sufficiently evidenced by a Partnership Request or Company
      Order (other than delivery of any Security, together with any coupons
      appertaining thereto, 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 may 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


                                       47
<Page>

      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 of Securities of any series or any related
      coupons pursuant to this Indenture, unless such Holders shall have offered
      to the Trustee security or indemnity reasonably satisfactory to the
      Trustee 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, coupon or other paper or document,
      unless requested in writing so to do by the Holders of not less than a
      majority in aggregate principal amount of the Outstanding Securities of
      any series; PROVIDED that, if the payment within a reasonable time to the
      Trustee of the costs, expenses or liabilities likely to be incurred by it
      in the making of such investigation is, in the opinion of the Trustee, not
      reasonably assured to the Trustee by the security afforded to it by the
      terms of this Indenture, the Trustee may require reasonable indemnity
      against such expenses or liabilities as a condition to proceeding; the
      reasonable expenses of every such examination shall be paid by the Holders
      or, if paid by the Trustee, shall be repaid by the Holders upon demand.
      The Trustee, in its discretion, may make such further inquiry or
      investigation into such facts or matters as it may see fit, and, if the
      Trustee shall determine to make such further inquiry or investigation, it
      shall be entitled to examine the books, records and premises of the
      Partnership, relevant to the facts or matters that are the subject of its
      inquiry, personally or by agent or attorney;

                  (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 shall not be liable for any action taken,
      suffered or omitted by it in good faith and reasonably believed by it to
      be authorized or within the discretion or rights or powers conferred upon
      it by this Indenture.

      The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.


                                       48
<Page>

      Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

      SECTION 603. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES. The
recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Partnership, and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Partnership of Securities or the proceeds thereof.

      SECTION 604. MAY HOLD SECURITIES. The Trustee, any Paying Agent, Security
Registrar, Authenticating Agent or any other agent of the Partnership, in its
individual or any other capacity, may become the owner or pledgee of Securities
and coupons and, subject to TIA Sections 310(b) and 311, may otherwise deal with
the Partnership with the same rights it would have if it were not Trustee,
Paying Agent, Security Registrar, Authenticating Agent or such other agent.

      SECTION 605. 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 606. 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);

                  (2) except as otherwise expressly provided herein, to
      reimburse each of the Trustee and any predecessor 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 reasonable 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 each of the Trustee and any predecessor
      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


                                       49
<Page>

      defending itself against any claim or liability in connection with the
      exercise or performance of any of its powers or duties hereunder.

      When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(7) or Section 501(8), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

      As security for the performance of the obligations of the Partnership
under this Section, the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of Principal of (or premium or Make-Whole Amount,
if any) or interest on particular Securities or any coupons.

      The provisions of this Section shall survive the termination of this
Indenture.

      SECTION 607. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY; CONFLICTING
INTERESTS. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
Federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. 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. Neither the Partnership nor
any Person directly or indirectly controlling, controlled by, or under common
control with the Partnership shall serve as Trustee.

      SECTION 608. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

            (a) 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 609.

            (b) 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 an instrument of acceptance by a successor Trustee 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.


                                       50
<Page>

            (c) 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.

            (d) If at any time:

                  (1) the Trustee shall fail to comply with the provisions of
      TIA Section 310(b) after written request therefor by the Partnership or by
      any Holder of a Security who has been a bona tide Holder of a Security for
      at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 607
      and shall fail to resign after written request therefor by the Partnership
      or by any Holder of a Security who has been a bona fide Holder of a
      Security for at least six months, 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, (i) the Partnership by or pursuant to a Board Resolution
may remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security 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.

            (e) 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 or pursuant
to 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). 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, 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 of Securities and accepted appointment in the manner hereinafter
provided, any Holder of a Security who has 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


                                       51
<Page>

situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to Securities of such series.

            (f) 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
in the manner provided for notices to the Holders of Securities 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 609. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) 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 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, subject nevertheless to its claim, if any,
provided for in Section 606.

            (b) 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, pursuant to Article Nine hereof, wherein each successor Trustee shall
accept such appointment and which (1) 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, (2) 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 (3) 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 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


                                       52
<Page>

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 relates; but, on request of the
Partnership or any successor Trustee, such retiring Trustee shall 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.

            (c) 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 (a) or (b) of this Section 609, as the case may be.

            (d) 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 610. 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 of 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 or coupons 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 or coupons so authenticated with
the same effect as if such successor Trustee had itself authenticated such
Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

      SECTION 611. APPOINTMENT OF AUTHENTICATING AGENT. At any time when any of
the Securities remain Outstanding, the Trustee 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 exchange, registration of transfer or partial redemption or
repayment thereof, 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. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the
Partnership. 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


                                       53
<Page>

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 bank or trust company or corporation organized and doing business
and in good standing under the laws of the United States of America or of any
state or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus (or having a holding
company parent with a combined capital and surplus) of not less than $50,000,000
and subject to supervision or examination by Federal or state authorities. If
such Authenticating Agent publishes reports of condition at least annually,
pursuant to law or the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such Authenticating Agent (or its parent, as the case may be) shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. In case 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 the corporate agency or
corporate trust business of an 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 further act
on the part of the Trustee or the Authenticating Agent.

      An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Partnership. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination 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 for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Partnership and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 106. 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 herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

      The Partnership agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.


                                       54

      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 or in lieu of the Trustees' certificate of authentication, an
alternate certificate of authentication substantially in the following form:

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

      SECTION 612. CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

      (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to the Securities of such
series:

            (1) the Trustee undertakes to perform such duties and only such
      duties as are specifically set forth in this Indenture, and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; and

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture; but
      in the case of any such certificates or opinions which by any provision
      hereof are specifically required to be furnished to the Trustee, the
      Trustee shall be under a duty to examine the same to determine whether or
      not they conform to the requirements of this Indenture, but shall not be
      under any duty to verify the contents or accuracy thereof.

      (b) In case an Event of Default with respect to the Securities of any
series has occurred and is continuing, the Trustee shall, with respect to
Securities of such series, exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.


                                       55
<Page>

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

            (1) this Subsection shall not be construed to limit the effect of
      Subsection (a) of this Section;

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

            (3) the Trustee shall not be liable with respect to any action taken
      or omitted to be taken by it in good faith in accordance with the
      direction of the Holders of a majority in principal amount of the
      Outstanding Securities of any series relating to the time, method and
      place of conducting any proceeding for any remedy available to the
      Trustee, or exercising any trust or power conferred upon the Trustee,
      under this Indenture with respect to the Securities of such series; and

            (4) 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 adequate indemnity against such risk or
      liability is not reasonably assured to it.

      (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
612.

Securities or coupons, by receiving and holding the same, agrees with the
Partnership and the Trustee that neither the Partnership nor the Trustee nor any
Authenticating Agent nor any Paying Agent nor any Security Registrar shall be
held accountable by reason of the disclosure of any information as to the names
and addresses of the Holders of Securities in accordance with TIA Section 312,

initially be not less than every twelve months commencing on [_______________].
A copy of each such report shall, at the time of such transmission to Holders,

      copies of such portions of any of the foregoing as the Commission may from
      time to time by rules and regulations prescribe) which the Partnership may
      be required to file with the Commission pursuant to Section 13 or Section

      not required to file information, documents or reports pursuant to either
      of such Sections, then it will file with the Trustee and the Commission,
      in accordance with rules and regulations prescribed from time to time by

      Indenture as may be required from time to time by such rules and
      regulations; and

                  (3) transmit by mail to the Holders of Securities, within 30

Trustee may reasonably require, of the names and addresses of the Holders of
Registered Securities of such series as of such Regular Record Date, or if there

                                       57
<Page>

Securities, semiannually, upon such dates as are set forth in the Board
Resolution or indenture supplemental hereto authorizing such series, and

            (b) at such other times as the Trustee may request in writing,
within 30 days after the receipt by the Partnership of any such request, a list
of similar form and content as of a date not more than 15 days prior to the time

        ARTICLE EIGHT - CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

      SECTION 801. CONSOLIDATIONS AND MERGERS OF PARTNERSHIP AND SALES, LEASES
AND CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS. The Partnership may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other entity, provided that in any such
case, (1) either the Partnership shall be the continuing entity, or the
successor entity shall be a entity organized and existing under the laws of the
United States or a State thereof and such successor entity shall expressly
assume the due and punctual payment of the principal of (and premium or
Make-Whole Amount, if any) and any interest on all of the Securities, according
to their tenor, and the due and punctual performance and observance of all of
the covenants and conditions of this Indenture to be performed by the
Partnership by supplemental indenture, complying with Article Nine hereof,
satisfactory to the Trustee, executed and delivered to the Trustee by such
entity and (2) immediately after giving effect to such transaction and treating
any indebtedness which becomes an obligation of the Partnership or any
Subsidiary as a result thereof as having been incurred by the Partnership or
such Subsidiary at the time of such transaction, no Event of Default, and no
event which, after notice or the lapse of time, or both, would become an Event
of Default, shall have occurred and be continuing.

      SECTION 802. RIGHTS AND DUTIES OF SUCCESSOR ENTITY. In case of any such
consolidation, merger, sale, lease or conveyance and upon any such assumption by
the successor entity, such successor entity shall succeed to and be substituted
for the Partnership, with the same effect as if it had been named herein as the
party of the first part, and the predecessor entity, except in the event of a
lease, shall be relieved of any further obligation under this Indenture and the
Securities. Such successor entity thereupon may cause to be signed, and may
issue either in its own name or in the name of the Partnership, any or all of
the Securities issuable hereunder which theretofore shall not have been signed
by the Partnership and delivered to the Trustee; and, upon the order of such
successor entity, instead of the Partnership, and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Securities which previously shall have been
signed and delivered by the officers of the Partnership to the Trustee for
authentication, and any Securities which such successor entity thereafter shall
cause to be


                                       58
<Page>

signed and delivered to the Trustee for that purpose. All the Securities so
issued shall in all respects have the same legal rank and benefit under this
Indenture as the Securities theretofore or thereafter issued in accordance with
the terms of this Indenture as though all of such Securities had been issued at
the date of the execution hereof.

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

      SECTION 803. OFFICERS' CERTIFICATE AND OPINION OF COUNSEL. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor entity, complies
with the provisions of this Article and that all conditions precedent herein
provided for relating to such transaction have been complied with.

      SECTION 901. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS. Without
the consent of any Holders of Securities or coupons, the Partnership, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time
and from time to time, may enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, for any of the following purposes:

                  (1) to evidence the succession of another Person to the
      Partnership and the assumption by any such successor of the covenants of
      the Partnership contained herein and in the Securities; or

                  (2) to add to the covenants of the Partnership for the benefit
      of the Holders of all or any series of Securities (and if such covenants
      are to be for the benefit of less than all series of Securities, stating
      that such covenants are expressly being included solely for the benefit of
      such series) or to surrender any right or power herein conferred upon the
      Partnership; or

                  (3) to add any additional Events of Default for the benefit of
      the Holders of all or any series of Securities (and if such Events of
      Default are to be for the benefit of less than all series of Securities,
      stating that such Events of Default are expressly being included solely
      for the benefit of such series); PROVIDED, HOWEVER, that in respect of any
      such additional Events of Default such supplemental indenture may provide
      for a particular period of grace after default (which period may be
      shorter or longer than that allowed in the case of other defaults) or may
      provide for an immediate enforcement upon such default or may limit the
      remedies available to the Trustee upon


                                       59
<Page>

      such default or may limit the right of the Holders of a majority in
      aggregate principal amount of that or those series of Securities to which
      such additional Events of Default apply to waive such default; or

                  (4) to add to or change any of the provisions of this
      Indenture to provide that Bearer Securities may be registrable as to
      principal, to change or eliminate any restrictions on the payment of
      principal of or premium or Make-Whole Amount, if any, or interest on
      Bearer Securities, to permit Bearer Securities to be issued in exchange
      for Registered Securities, to permit Bearer Securities to be issued in
      exchange for Bearer Securities of other authorized denominations or to
      permit or facilitate the issuance of Securities in uncertificated form,
      PROVIDED that any such action shall not adversely affect the interests of
      the Holders of Securities of any series or any related coupons in any
      material respect; or

                  (5) to change or eliminate any of the provisions of this
      Indenture, PROVIDED that any such change or elimination shall become
      effective only when there is no Security Outstanding of any series created
      prior to the execution of such supplemental indenture which is entitled
      to the benefit of such provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
      and any related coupons as permitted by Sections 201 and 301; or

                  (8) to evidence and provide for the acceptance of appointment
      hereunder by a successor Trustee with respect to the Securities of one or
      more series and to 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; or

                  (9) to cure any ambiguity, to correct or supplement any
      provision herein which may be defective or inconsistent with any other
      provision herein, or to make any other provisions with respect to matters
      or questions arising under this Indenture which shall not be inconsistent
      with the provisions of this Indenture, PROVIDED such provisions shall not
      adversely affect the interests of the Holders of Securities of any series
      or any related coupons in any material respect; or

                  (10) to supplement any of the provisions of this Indenture to
      such extent as shall be necessary to permit or facilitate the defeasance
      and discharge of any series of Securities pursuant to Sections 401, 1402
      and 1403; PROVIDED that any such action shall not adversely affect the
      interests of the Holders of Securities of such series and any related
      coupons or any other series of Securities in any material respect.

      SECTION 902. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS. With the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Securities affected by such supplemental indenture, by Act of said
Holders delivered to the Partnership and the Trustee, the Partnership, when
authorized by or pursuant to a Board Resolution, and the Trustee may enter into

      interest on, any Security; or reduce the principal amount thereof or the
      rate or amount of interest thereon, or any premium or Make-Whole Amount

      or Section 1009, except to increase the required percentage to effect such
      action or to provide that certain other provisions of this Indenture
      cannot be modified or waived without the consent of the Holder of each
      Outstanding Security affected thereby, PROVIDED, HOWEVER, that this clause
      shall not be deemed to require the consent of any Holder with respect to
      changes in the references to "the Trustee" and concomitant changes in this
      Section 902 and Section 1009, or the deletion of this proviso, in
      accordance with the requirements of Sections 609(b) and 901(11).

<Page>

      It shall not be necessary for any Act of Holders under this Section 902 to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

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

AND INTEREST. The Partnership covenants and agrees for the benefit of the
Holders of each series of Securities that it will duly and punctually calculate

<Page>

Section 301 with respect to any series of Securities, any interest due on Bearer
Securities on or before Maturity shall be payable only upon presentation and
surrender of the several coupons for such interest installments as are evidenced
thereby as they severally mature. Unless otherwise specified with respect to
Securities of any series pursuant to Section 301, at the option of the
Partnership, all payments of principal may be paid by check to the registered
Holder of the Registered Security or other person entitled thereto against

      SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY. If Securities of a series

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. If Securities of
a series are issuable as Bearer Securities, the Partnership will maintain: (A)
in the Borough of Manhattan, The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where notices and demands to or upon the Partnership in respect of the
Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered
for payment in the circumstances described in the following paragraph (and not
otherwise); (B) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series which is located outside the United States, an
office or agency where Securities of that series and related coupons may be
presented and surrendered for payment; PROVIDED, HOWEVER, that if the Securities
of that series are listed on any stock exchange located outside the United
States and such stock exchange shall so require, the Partnership will maintain a
Paying Agent for the Securities of that series in any required city located
outside the United States, as the case may be, so long as the Securities of that
series are listed on such exchange; and (C) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series located outside the
United States an office or agency where any Registered Securities of that series
may be surrendered for registration of transfer, where Securities of that series
may be surrendered for 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 each 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, except that Bearer Securities of that
series and the related coupons may be presented and surrendered for payment at
the offices specified in the Security and the Partnership hereby appoints the
same as its agent to receive such respective presentations, surrenders, notices
and demands, and the Partnership hereby


                                       63
<Page>

appoints the Trustee its agent to receive all such presentations, surrenders,
notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or Make-Whole Amount or interest
on Bearer Securities shall be made at any office or agency of the Partnership in
the United States or by check mailed to any address in the United States or by
transfer to an account maintained with a bank located in the United States;
PROVIDED, HOWEVER, that, if the Securities of a series are payable in Dollars,
payment of principal of and any premium or Make-Whole Amount and interest on any
Bearer Security shall be made at the Corporate Trust Office of the Trustee in
Boston, Massachusetts if (but only if) payment in Dollars of the full amount of
such principal, premium or Make-Whole Amount, or interest, as the case may be,
at all offices or agencies outside the United States maintained for the purpose
by the Partnership in accordance with this Indenture, is illegal or effectively
precluded by exchange controls or other similar restrictions.

      The Partnership may 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 of 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 accordance with the requirements set forth above 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. Unless otherwise
specified with respect to any Securities pursuant to Section 301 with respect to
a series of Securities, the Partnership hereby designates as a Place of Payment
for each series of Securities the office or agency of the Corporate Trust Office
of the Trustee in Boston, Massachusetts, and initially appoints the Trustee at
its Corporate Trust Office as Paying Agent in such city and as its agent to
receive all such presentations, surrenders, notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the
Partnership will maintain with respect to each such series of Securities, or as
so required, at least one exchange rate agent.

      SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST. If the
Partnership shall at any time act as its own Paying Agent with respect to any
series of any Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), 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 in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay the principal
(and premium or Make-Whole


                                       64
<Page>

Amount, if any) or interest so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided, and will promptly
notify the Trustee of its action or failure so to act.

      Whenever the Partnership shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, before each due date of
the principal of (and premium or Make-Whole Amount, if any), or interest on any
Securities of that series, deposit with a Paying Agent a sum (in the currency or
currencies, currency unit or units or composite currency or currencies described
in the preceding paragraph) sufficient to pay the principal (and premium or
Make-Whole Amount, if any) or interest so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or
Make-Whole Amount, if any, or interest 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 principal of
      (and premium or Make-Whole Amount, if any) or interest on Securities 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 Trustee written notice of any default by the
      Partnership (or any other obligor upon the Securities) in the making of
      any such payment of principal (and premium or Make-Whole Amount, if any)
      or interest on the Securities of that series; and

                  (3) at any time during the continuance of any such default
      upon the written request of the Trustee, forthwith pay to the Trustee all
      sums so held in trust by such Paying Agent.

      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 Company 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 sums.

      Except as otherwise provided in the Securities of any series, 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 (and premium or Make-Whole Amount,
if any) or interest on any Security of


                                       65
<Page>

any series and remaining unclaimed for two years after such principal (and
premium or Make-Whole Amount, if any) or interest has become due and payable
shall be paid to the Partnership upon 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 of such principal of (and premium or Make-Whole Amount,
if any) or interest on any Security, without interest thereon, 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, 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. EXISTENCE. Subject to Article Eight, the Partnership will do
or cause to be done all things necessary to preserve and keep in full force and
effect its partnership existence, all material rights (by partnership agreement
and statute) and material franchises; PROVIDED, HOWEVER, that the Partnership
shall not be required to preserve any such right or franchise if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Partnership.

      SECTION 1005. MAINTENANCE OF PROPERTIES. The Partnership will cause all of
its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Partnership may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; PROVIDED, HOWEVER, that the Partnership and its
Subsidiaries shall not be prevented from selling or otherwise disposing of their
properties for value in the ordinary course of business.

      SECTION 1006. INSURANCE. The Partnership will cause each of its and its
Subsidiaries' insurable properties to be insured against loss or damage in an
amount at least equal to their then full insurable value with insurers of
recognized responsibility.

      SECTION 1007. PAYMENT OF TAXES AND OTHER CLAIMS. The Partnership will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Partnership or any Subsidiary, and (2) all lawful claims for labor, materials
and supplies which, if unpaid, might by law become a lien upon the property of
the Partnership or any Subsidiary; PROVIDED, HOWEVER, that the Partnership shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment,


                                       66
<Page>

charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings.

      SECTION 1008. STATEMENT AS TO COMPLIANCE. The Partnership will deliver to
the Trustee, within 120 days after the end of each fiscal year, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer of the Company as general partner of the
Partnership as to his or her knowledge of the Partnership's compliance with all
conditions and covenants under this Indenture and, in the event of any
noncompliance, specifying such noncompliance and the nature and status thereof.
For purposes of this Section 1008, such compliance shall be determined without
regard to any period of grace or requirement of notice under this Indenture.

      SECTION 1009. WAIVER OF CERTAIN COVENANTS. The Partnership may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1009, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant 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.

                    ARTICLE ELEVEN - 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 or pursuant to a
Board Resolution. In case of any redemption at the election of the Partnership
of less than all of the Securities of any series, the Partnership will notify
the Trustee, at least 45 days prior to the giving of the notice of redemption in
Section 1104 (or such shorter period as is satisfactory to the Trustee), of such
Redemption Date and of the aggregate principal amount and series of Securities
to be redeemed. In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, the Partnership shall furnish the
Trustee with an Officers' Certificate evidencing compliance with such
restriction.

      SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED. If less
than all the Securities of any series issued on the same day with the same terms
are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the


                                       67
<Page>

Redemption Date by the Trustee, from the Outstanding Securities of the
applicable series issued on such date with the same terms not previously called
for redemption, by such method as the Trustee shall deem fair and appropriate
and which may provide for the selection for redemption in part (in 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 and the Security
Registrar (if other than itself) 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 Security redeemed or to be redeemed only in part, to the portion of
the principal amount of such Security which has been or is to be redeemed.

      SECTION 1104. NOTICE OF REDEMPTION. Notice of redemption shall be given in
the manner provided in Section 106, not more than 60 days nor less than 30 days
prior to the Redemption Date, unless a shorter period is specified by the terms
of such series established pursuant to Section 301, to each Holder of Securities
to be redeemed, but failure to give such notice in the manner herein provided to
the Holder of any Security designated for redemption as a whole or in part, or
any defect in the notice to any such Holder, shall not affect the validity of
the proceedings for the redemption of any other such Security or portion
thereof.

      Any notice that is mailed to the Holders of Registered Securities in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Holder receives the notice.

      All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price, accrued interest to, but not
      including, the Redemption Date payable as provided in Section 1106, if
      any,

                  (3) if less than all Outstanding Securities of any series are
      to be redeemed, the identification (and, in the case of partial
      redemption, the principal amount) of the particular Security or Securities
      to be redeemed,

                  (4) in case any Security is to be redeemed in part only, the
      notice which relates to such Security shall state that on and after the
      Redemption Date, upon surrender of such Security, the holder will receive,
      without a charge, a new Security or


                                       68
<Page>

      Securities of authorized denominations for the principal amount thereof
      remaining unredeemed,

                  (5) that on the Redemption Date the Redemption Price and
      accrued interest to, but not including, the Redemption Date payable as
      provided in Section 1106, if any, will become due and payable upon each
      such Security, or the portion thereof, to be redeemed and, if applicable,
      that interest thereon shall cease to accrue on and after said date,

                  (6) the Place or Places of Payment where such Securities,
      together in the case of Bearer Securities with all coupons appertaining
      thereto, if any, maturing after the Redemption Date, are to be surrendered
      for payment of the Redemption Price and accrued interest, if any,

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

                  (8) that, unless otherwise specified in such notice, Bearer
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all coupons maturing subsequent to the date fixed for
      redemption or the amount of any such missing coupon or coupons will be
      deducted from the Redemption Price, unless security or indemnity
      satisfactory to the Partnership, the Trustee for such series and any
      Paying Agent is furnished,

                  (9) if Bearer Securities of any series are to be redeemed and
      any Registered Securities of such series are not to be redeemed, and if
      such Bearer Securities may be exchanged for Registered Securities not
      subject to redemption on this Redemption Date pursuant to Section 305 or
      otherwise, the last date, as determined by the Partnership, on which such
      exchanges may be made, and

                  (10) the CUSIP number of such Security, if any.

      Notice of redemption of Securities to be redeemed at the election of the
Partnership 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. 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, which it may not do in the
case of a sinking fund payment under Article Twelve, segregate and hold in trust
as provided in Section 1003) an amount of money in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay on the
Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment


                                       69
<Page>

Date) accrued interest to but not including such Redemption Date on, all the
Securities or portions thereof which are to be redeemed on that date.

      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 in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) (together with accrued interest, if any, to but not including the
Redemption Date), and from and after such date (unless the Partnership shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void. Upon surrender of
any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Partnership at the Redemption Price, together
with accrued interest, if any, to but not including the Redemption Date;
PROVIDED, HOWEVER, that installments of interest on Bearer Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable only at
an office or agency located outside the United States (except as otherwise
provided in Section 1002) and, unless otherwise specified as contemplated by
Section 301, only upon presentation and surrender of coupons for such interest;
and PROVIDED further that installments of interest on Registered Securities
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 Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Partnership and the Trustee if there be furnished
to them such security or indemnity as they may require to save each of them and
any Paying Agent harmless. If thereafter the Holder of such Security shall
surrender to the Trustee or any Paying Agent any such missing coupon in respect
of which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; PROVIDED, HOWEVER, that
interest represented by coupons shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons.

      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium or Make-Whole Amount, if any)
shall, until paid, bear interest from the Redemption Date at the rate borne by
the Security.

<Page>

      SECTION 1107. SECURITIES REDEEMED IN PART. Any Registered Security which
is to be redeemed only in part (pursuant to the provisions of this Article or of
Article Twelve) 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, 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. If a Global
Security is so surrendered, the Partnership shall execute and the Trustee shall
authenticate and deliver to the depository, without service charge, a new Global
Security in a denomination equal to and in exchange for the unredeemed portion
of the principal of the Global Security so surrendered.

                         ARTICLE TWELVE - 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 such Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of any Securities of any
series, the cash amount of any mandatory 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.

      SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES. The
Partnership may, in satisfaction of all or any part of any mandatory sinking
fund payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such 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, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Partnership; PROVIDED that such Securities so delivered or applied as a credit
have not been previously so credited. Such Securities shall be received and
credited for such purpose by the Trustee at the applicable Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such mandatory sinking fund payment shall be reduced
accordingly.


                                       71
<Page>

      SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than 60
days prior to each sinking fund payment date for Securities of any series, the
Partnership will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing mandatory 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 in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Partnership shall thereupon be obligated to pay the
amount therein specified. 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 THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

      SECTION 1301. APPLICABILITY OF ARTICLE. Repayment of Securities of any
series before their Stated Maturity at the option of Holders thereof shall be
made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.

      SECTION 1302. REPAYMENT OF SECURITIES. Securities of any series subject to
repayment in whole or in part at the option of the Holders thereof will, unless
otherwise provided in the terms of such Securities, be repaid at a price equal
to the principal amount thereof, together with interest, if any, thereon accrued
to but not including the Repayment Date specified in or pursuant to the terms of
such Securities. The Partnership covenants that prior to the Repayment Date it
will 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 in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest to but not including such Repayment Date on, all the Securities or
portions thereof, as the case may be, to be repaid on such date.

      SECTION 1303. EXERCISE OF OPTION. Securities of any series subject to
repayment at the option of the Holders thereof will contain an "Option to Elect
Repayment" form on the reverse of such Securities. In order for any Security to
be repaid at the option of the Holder, the Trustee must receive at the Place of
Payment therefor specified in the terms of such Security (or at such other place
or places of which the Partnership shall from time to time notify the Holders of
such Securities) not earlier than 60 days nor later than 30 days prior to the
Repayment Date (1) the Security so providing for such repayment together with
the "Option to Elect Repayment" form on the reverse thereof duly completed by
the Holder (or by the Holder's attorney duly authorized in writing) or (2) a
telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the National Association of Securities Dealers, Inc.
("NASD"), or a commercial bank or trust company in the United States setting
forth the name of the Holder of the Security, the principal amount of the
Security, the principal amount of the Security to be repaid, the CUSIP number,
if any, or a description of the tenor and terms of the Security, a statement
that the option to elect repayment is being exercised thereby and a guarantee
that the Security to be repaid, together with the duly completed form entitled
"Option to Elect Repayment" on the reverse of the Security, will be received by
the Trustee not later than the fifth Business Day after the date of such
telegram, telex, facsimile transmission or letter; PROVIDED, HOWEVER, that such
telegram, telex, facsimile transmission or letter shall only be effective if
such Security and form duly completed are received by the Trustee by such fifth
Business Day. If less than the entire principal amount of such Security is to be
repaid in accordance with the terms of such Security, the principal amount of
such Security to be repaid, in increments of the minimum denomination for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part. Except as otherwise may be provided by the terms of any
Security providing for repayment at the option of the Holder thereof, exercise
of the repayment option by the Holder shall be irrevocable unless waived by the
Partnership.

      SECTION 1304. WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND
PAYABLE. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Partnership on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Partnership shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the


                                       73
<Page>

principal amount of such Security so to be repaid shall be paid by the
Partnership, together with accrued interest, if any, to but not including the
Repayment Date; PROVIDED, HOWEVER, that coupons whose Stated Maturity is on or
prior to the Repayment Date shall be payable only at an office or agency located
outside the United States (except as otherwise provided in Section 1002) and,
unless otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and PROVIDED FURTHER that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable (but without interest thereon,
unless the Partnership shall default in the payment thereof) 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 Bearer Security surrendered for repayment shall not be accompanied
by all appurtenant coupons maturing after the Repayment Date, such Security may
be paid after deducting from the amount payable therefor as provided in Section
1302 an amount equal to the face amount of all such missing coupons, or the
surrender of such missing coupon or coupons may be waived by the Partnership and
the Trustee if there be furnished to them such security or indemnity as they may
require to save each of them and any Paying Agent harmless. If thereafter the
Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing coupon in respect of which a deduction shall have been made as
provided in the preceding sentence, such Holder shall be entitled to receive the
amount so deducted; PROVIDED, HOWEVER, that interest represented by coupons
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of those
coupons.

      If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to but not including such Repayment Date)
shall, until paid, bear interest from the Repayment Date at the rate of interest
or Yield to Maturity (in the case of Original Issue Discount Securities) set
forth in such Security.

      SECTION 1305. SECURITIES REPAID IN PART. Upon surrender of any Registered
Security which is to be repaid in part only, the Partnership shall execute and
the Trustee shall authenticate and deliver to the Holder of such Security,
without service charge and at the expense of the Partnership, a new Registered
Security or Securities of the same series, of any authorized denomination
specified by the Holder, in an aggregate principal amount equal to and in
exchange for the portion of the principal of such Security so surrendered which
is not to be repaid.

              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

      SECTION 1401. APPLICABILITY OF ARTICLE; PARTNERSHIP'S OPTION TO EFFECT
DEFEASANCE OR COVENANT DEFEASANCE. If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the Partnership may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.

      SECTION 1402. DEFEASANCE AND DISCHARGE. Upon the Partnership's exercise of
the above option applicable to this Section with respect to any Securities of or
within a series, the Partnership shall be deemed to have been discharged from
its obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Partnership shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Partnership, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium
or Make-Whole Amount, if any) and interest, if any, on such Securities and any
coupons appertaining thereto when such payments are due, (B) the Partnership's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article
Fourteen, the Partnership may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 1403 with respect
to such Securities and any coupons appertaining thereto.

      SECTION 1403. COVENANT DEFEASANCE. Upon the Partnership's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Partnership shall be released from its obligations under
Sections 1004 to 1009, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant contained herein or in any indenture
supplemental hereto, with respect to such Outstanding Securities and any


                                       75
<Page>

coupons appertaining thereto on and after the date the conditions set forth in
Section 1404 are satisfied (hereinafter, "covenant defeasance"), and such
Securities and any coupons appertaining thereto shall thereafter be deemed to be
not "Outstanding" for the purposes of any direction, waiver, consent or
declaration or Act of Holders (and the consequences of any thereof) in
connection with Sections 1004 to 1009, inclusive, or such other covenant, but
shall continue to be deemed "Outstanding" for all other purposes hereunder. For
this purpose, such covenant defeasance means that, with respect to such
Outstanding Securities and any coupons appertaining thereto, 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 or such other covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such Section or such other covenant or by reason of reference in any such
Section or such other covenant 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(4) or 501(8) or otherwise, as the case may be, but,
except as specified above, the remainder of this Indenture and such Securities
and any coupons appertaining thereto shall be unaffected thereby.

      SECTION 1404. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The
following shall be the conditions to application of Section 1402 or Section 1403
to any outstanding Securities of or within a series and any coupons appertaining
thereto:

            (a) The Partnership shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen applicable to it) 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 such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with their terms will provide, not later than the due date of any
payment of principal of (and premium or Make-Whole Amount, if any) and interest,
if any, on such Securities and any coupons appertaining thereto, money in an
amount, or (3) a combination thereof, in any case, in an amount, sufficient,
without consideration of any reinvestment of such principal and interest, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, (i) the principal of (and premium or Make-Whole
Amount, if any) and interest, if any, on such Outstanding Securities and any
coupons appertaining thereto on the Stated Maturity of such principal or
installment of principal or interest and (ii) any mandatory sinking fund
payments or analogous payments applicable to such Outstanding Securities and any
coupons appertaining thereto on the day on which such payments are due and
payable in


                                       76
<Page>

accordance with the terms of this Indenture and of such Securities and any
coupons appertaining thereto.

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

            (c) No Event of Default or event which with notice or lapse of time
or both would become an Event of Default with respect to such Securities and any
coupons appertaining thereto shall have occurred and be continuing on the date
of such deposit or, insofar as Sections 501(6) and 501(7) are concerned, at any
time during the period ending on the 91st day after the date of such deposit (it
being understood that this condition shall not be deemed satisfied until the
expiration of such period).

            (d) In the case of an election under Section 1402, the Partnership
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Partnership has received from, or there has been published by, the Internal
Revenue Service a ruling, or (ii) since the date of execution of this Indenture,
there has been a change in the applicable Federal income tax law, in either case
to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such defeasance and will be subject to Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such defeasance had not occurred.

            (e) In the case of an election under Section 1403, the Partnership
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred.

            (f) The Partnership shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Partnership's option under
Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Partnership, with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

            (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms,


                                       77
<Page>

conditions or limitations which may be imposed on the Partnership in connection
therewith pursuant to Section 301.

      SECTION 1405. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto 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 Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium or Make-Whole Amount, if any) and interest, but such money need not be
segregated from other funds except to the extent required by law.

      Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable market exchange rate for such currency or currency unit in
effect on the second Business Day prior to each payment date, except, with
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

      The Partnership shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any coupons
appertaining thereto.

      Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Partnership from time to
time upon Partnership Request any


                                       78
<Page>

money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in Section 1404 which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect a defeasance or
covenant defeasance, as applicable, in accordance with this Article.

      SECTION 1501. PURPOSES FOR WHICH MEETINGS MAY BE CALLED. A meeting of

      SECTION 1502. CALL, NOTICE AND PLACE OF MEETINGS. (a) The Trustee may at
any time call a meeting of Holders of Securities of any series for any purpose
specified in Section 1501, to be held at such time and at such place as the
Trustee shall determine. Notice of every meeting of Holders of Securities of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided in Section 106, not less than 20 nor more than 180 days prior to

Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1501, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 20 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Partnership or the Holders of Securities of such
series in the amount above specified, as the case may be, may determine the time

      SECTION 1504. QUORUM; ACTION. The Persons entitled to vote a majority in
principal amount of the Outstanding Securities of a series shall constitute a
quorum for a meeting of Holders of Securities of such series; PROVIDED, HOWEVER,
that if any action is to be taken at such meeting with respect to a consent or
waiver which this Indenture expressly provides may be given by the Holders of
not less than a specified percentage in principal amount of the Outstanding

the chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at the reconvening of any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10
days; at the reconvening of any meeting adjourned or further adjourned for lack

reconvening of any adjourned meeting shall be given as provided in Section
1502(a), except that such notice need be given only once not less than five days
prior to the date on which the meeting is scheduled to be reconvened.

      Except as limited by the proviso to Section 902, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present
as aforesaid may be adopted by the affirmative vote of the persons entitled to
vote a majority in aggregate principal amount of the Outstanding Securities
represented at such meeting; PROVIDED, HOWEVER, that, except as limited by the
proviso to Section 902, any resolution with respect to any request, demand,
authorization, direction, notice, consent, waiver or other action which this
Indenture expressly provides may be made, given or taken by the Holders of a
specified percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Securities of that series.

      Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

      Notwithstanding the foregoing provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:


                                       80
<Page>

                  (i) there shall be no minimum quorum requirement for such
      meeting; and

                  (ii) the principal amount of the Outstanding Securities of
      such series that vote in favor of such request, demand, authorization,
      direction, notice, consent, waiver or other action shall be taken into
      account in determining whether such request, demand, authorization,
      direction, notice, consent, waiver or other action has been made, given or
      taken under this Indenture.

      SECTION 1505. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
MEETINGS. (a) Notwithstanding any provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

            (b) The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Partnership or by Holders of Securities as provided in Section 1502(b), in
which case the Partnership or the Holders of Securities of the series calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in principal amount
of the Outstanding Securities of such series represented at the meeting.

            (c) At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; PROVIDED,
HOWEVER that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

            (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series


                                       81
<Page>

represented at the meeting, and the meeting may be held as so adjourned without
further notice.

      SECTION 1506. COUNTING VOTES AND RECORDING ACTION OF MEETINGS. The vote
upon any resolution submitted to any meeting of Holders of Securities of any
series shall be by written ballots on which shall be subscribed the signatures
of the Holders of Securities of such series or of their representatives by proxy
and the principal amounts and serial numbers of the Outstanding Securities of
such series held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record, at least in duplicate, of the proceedings
of each meeting of Holders of Securities of any Series shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the fact, setting forth a
copy of the notice of the meeting and showing that said notice was given as
provided in Section 1502 and, if applicable, Section 1504. Each copy shall be
signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one such copy shall be delivered to the Partnership and another
to the Trustee to be preserved by the Trustee, the latter to have attached
thereto the ballots voted at the meeting. Any record so signed and verified
shall be conclusive evidence of the matters therein stated.
