by interpolation, on a straight-line basis, between the weekly average yields on
the United States Treasury Notes that have a constant maturity closest to and
greater than the Remaining Term and the United States Treasury Notes that have a
constant maturity closest to and less than the Remaining Term (in each case as
set forth in the H.15 Statistical Release). Any weekly average yields so
calculated by interpolation will be rounded to the nearest 1/100th of 1% with
any figure of 1/200% or above being rounded upward. If weekly average yields for
United States Treasury Notes are not available in the H.15 Statistical Release
or otherwise, then the Treasury Yield will be calculated by interpolation of
comparable rates selected by the Independent Investment Banker.

such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

General Partner or a Guarantor may be based, insofar as it relates to legal
matters, upon a certificate or opinion of, or representations by, counsel,
unless such officer knows, or in the exercise of reasonable care should know,
that the certificate or opinion or representations with respect to the matters
upon which his certificate or opinion is based are erroneous. Any such
certificate or opinion of counsel may be based, insofar as it relates to factual
matters, upon a certificate or opinion of, or representations by, an officer or
officers of the Partnership, the General Partner or such Guarantor stating that
the information with respect to such factual matters is in the possession of the
Partnership, the General Partner or such Guarantor, unless such counsel knows
that the certificate or opinion or representations with respect to such matters
are erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 104. Acts of Holders; Record Dates.

Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed (either physically or by means of a facsimile
or an electronic transmission, provided that such electronic transmission is
transmitted through the facilities of a Depositary) by such Holders in person or
by an agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered (either physically or by means of a facsimile or an electronic
transmission, provided that such electronic transmission is transmitted through
the facilities of a Depositary) to the Trustee and, where it is hereby expressly
required, to the Partnership. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of Holders signing such instrument or instruments. Proof of execution of
any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 315 of the
Trust Indenture Act)



                                       16
<PAGE>   24


conclusive in favor of the Trustee and the Partnership, if made in the manner
provided in this Section.

         Without limiting the generality of the foregoing, a Holder, including a
Depositary that is a Holder of a Global Security, may make, give or take, by a
proxy or proxies, duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other action provided in this Indenture to
be made, given or taken by Holders, and a Depositary that is a Holder of a
Global Security may provide its proxy or proxies to the beneficial owners of
interests in any such Global Security.

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

         The ownership, principal amount and serial numbers of Securities held
by any Person, and the date of commencement of such Person's holding the same,
shall be proved by the Security Register.

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

         The Partnership may set any day as the record date for the purpose of
determining Holders of Outstanding Securities of either Series entitled to give
or take any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given or taken by
Holders of Securities of such Series (other than any such action provided or
permitted to be taken under Section 501, 502 or 512), but the Partnership shall
have no obligation to do so. Such record date shall be not earlier than the 30th
day prior to the first solicitation of any Holder to give or take any such
action and not later than the date of such first solicitation. With regard to
any record date set pursuant to this paragraph, Holders of Outstanding
Securities of the relevant Series on such record date (or their duly appointed
agents), and only such Persons, shall be entitled to give or take the relevant
action, whether or not such Holders remain Holders after such record date. The
Partnership shall notify the Trustee in writing of any such record date not
later than the date of the first solicitation of any Holder to give or take any
action.

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

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

                  (1) the Trustee by any Holder or by the Partnership or any
Guarantor shall be sufficient for every purpose hereunder if made in writing and
actually received by the Trustee at its Corporate Trust Office, Attention:
Corporate Trustee Administration, or at any other address previously furnished
in writing by the Trustee, or

                  (2) the Partnership or any Guarantor by the Trustee or by any
Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
the Partnership addressed to it at 1301 McKinney Street, Suite 3400, Houston
Texas, 77010, to the attention of the Corporate Secretary, or at any other
address previously furnished in writing to the Trustee by the Partnership.
Notice to the Partnership shall constitute notice to each Guarantor, if any.

SECTION 106. Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid (if international mail, by
air mail), to each Holder affected by such event, at his address as it appears
in the Security Register, not later than the latest date (if any), and not
earlier than the earliest date (if any), prescribed for the giving of such
notice. In any case where notice to Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders. Any notice mailed to a Holder in the manner herein prescribed
shall be conclusively deemed to have been received by such Holder, whether or
not such Holder actually receives such notice.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

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

govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or excluded, as the case may be.

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

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111. Benefits of Indenture.

shall give to any Person, other than the parties hereto and their successors
hereunder and Holders, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

SECTION 113. Legal Holidays.

payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, provided
that no interest shall accrue

         The interest so payable [(including Additional Interest, if any,
provided for on the reverse hereof)],(2) and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in said Indenture, be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, which shall be March 1 or September 1 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date.
Any such interest not so punctually paid or duly provided for will forthwith
cease to be payable to the Holder on such Regular Record Date and may either be
paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee, notice
whereof shall be given to Holders of Securities not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in said Indenture. Payment of the principal
of and interest on this Security will be made at the office or agency of the
Partnership maintained for that purpose in The City of New York, New York, in
such coin or currency of the United States as at the time of payment is legal
tender for payment of public and private debts; provided, however, that at the
option of the Partnership payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register; and provided, further, however, that in case this Security is
held by a Depositary or its nominee, payments of principal, interest and
premium, if any, shall be made by wire transfer of immediately available funds
to an account designated by such Depositary.

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

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

         IN WITNESS WHEREOF, the Partnership has caused this instrument to be
duly executed.

SECTION 203. Forms of Reverse of Securities.

                  (a) Form of Reverse of Floating Rate Security.

         This Security is one of a duly authorized issue of securities of the
Partnership, limited in aggregate principal amount to $400,000,000, issued and
to be issued under an Indenture, dated as of March 22, 2000 (herein called the
"Indenture"), between the Partnership and First Union National Bank, as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Partnership, the Trustee and
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered. The Securities issued and to be issued
under the Indenture consist of two Series of Senior Notes ($200,000,000
aggregate original principal amount of Floating Rate Senior Notes due 2002, and
$200,000,000 aggregate original principal amount of 8% Senior Notes due 2005)
and are hereinafter called the "Securities". This Security is one of the Series
of Floating Rate Securities referred to in the Indenture.

         The Floating Rate Securities will bear interest from March 22, 2000 at
a floating rate determined in the manner provided below, payable quarterly on
each Interest Payment Date commencing June 22, 2000, to Holders in whose name
the Floating Rate Securities are registered at the close of business on the
Regular Record Date for such Interest Payment Date.

         The per annum interest rate on the Floating Rate Securities (the
"Floating Interest Rate") in effect for each day of an Interest Period (as
defined below) will be equal to the Three-Month LIBOR Rate plus 50 basis points
(0.50%). The Floating Interest Rate for each Interest Period will be set on the
22nd day of the months of March, June, September and December of each year,
commencing March 22, 2000 (each such date, an "Interest Reset Date"), until the
principal on the Floating Rate Securities is paid or made available for payment
(the "Principal Payment Date"). If any Interest Reset Date and Interest Payment
Date would otherwise be a day that is not a Business Day, such Interest Reset
Date and Interest Payment Date shall be the next succeeding Business Day.

         "Interest Period" shall mean the period from and including an Interest
Reset Date to but excluding the next succeeding Interest Reset Date and, in the
case of the last such period, from and including the Interest Reset Date
immediately preceding the Principal Payment Date, as the case may be, to but not
including the Principal Payment Date. If the Principal Payment Date is not a
Business Day, then the principal amount of the Floating Rate Securities plus
accrued and unpaid interest thereon shall be paid on the next succeeding
Business Day and no interest shall accrue for the Principal Payment Date or any
day thereafter.



                                       24
<PAGE>   32


         The "Three-Month LIBOR Rate" shall mean the rate determined in
accordance with the following provisions:

                           (i) On the second Business Day preceding each
         Interest Reset Date (each such date, an "Interest Determination Date"),
         First Union National Bank (it and each other Person so appointed by the
         Partnership, the "Calculation Agent") will determine the Three-Month
         LIBOR Rate which shall be the rate for deposits in the London interbank
         market in Dollars having a three-month maturity commencing on the
         second Business Day immediately following such Interest Determination
         Date which appears on the Telerate Page 3750 as of 11:00 a.m., London
         time, on such Interest Determination Date. "Telerate Page 3750" means
         the display on Page 3750 of the Dow Jones Telerate Service (or such
         other page as may replace that page on that service for the purpose of
         displaying London interbank offered rates of major banks for Dollar
         deposits). If the Three-Month LIBOR Rate on such Interest Determination
         Date does not appear on the Telerate Page 3750, such Three-Month LIBOR
         Rate will be determined as described in (ii) below.

                           (ii) With respect to an Interest Determination Date
         for which the Three-Month LIBOR Rate does not appear on the Telerate
         Page 3750 as specified in (i) above, the Calculation Agent will request
         the principal London offices of each of four major banks in the London
         interbank market, as selected by the Calculation Agent, to provide the
         Calculation Agent with its offered quotation for deposits in Dollars
         having a three-month maturity commencing on the second Business Day
         immediately following such Interest Determination Date to prime banks
         in the London interbank market at approximately 11:00 a.m., London
         time, on such Interest Determination Date and in a principal amount
         that is representative for a single transaction in that market at such
         time. If at least two quotations are provided, the Three-Month LIBOR
         Rate on such Interest Determination Date will be the arithmetic mean
         (rounded upwards, if necessary, to the nearest one hundred-thousandth
         of a percentage point, with 5 or more one-millionths of one percentage
         point rounded upwards) of such quotations. If fewer than two quotations
         are provided, the Three-Month LIBOR Rate determined on such Interest
         Determination Date will be the arithmetic mean (rounded upwards, if
         necessary, to the nearest one hundred-thousandth of a percentage point,
         with 5 or more one-millionths of one percentage point rounded upwards)
         of the rates quoted at approximately 11:00 a.m., New York City time, on
         such Interest Determination Date for loans in Dollars to leading
         European banks, having a three-month maturity commencing on the second
         Business Day immediately following such Interest Determination Date and
         in a principal amount that is representative for a single transaction
         in that market at such time by three major banks in The City of New
         York, selected by the Calculation Agent. However, if the banks so
         selected by the Calculation Agent are not quoting as aforesaid, the
         Three-Month LIBOR Rate with respect to such Interest Determination
         Date will be the Three-Month LIBOR Rate in effect on such Interest
         Determination Date.



                                       25

<PAGE>   33


         The amount of interest for each day that a Floating Rate Security is
Outstanding (the "Daily Interest Amount") will be calculated by dividing the
Floating Interest Rate in effect for such day by 360 and multiplying the result
by the principal amount of such Floating Rate Security. The amount of interest
to be paid on such Floating Rate Security for any Interest Period will be
calculated by adding the Daily Interest Amounts for each day in such Interest
Period.

         The Floating Interest Rate will in no event be higher than the maximum
rate permitted by the law of the State of New York, or, if higher, the law of
the United States of America.

         The Floating Interest Rate and amount of interest to be paid on the
Floating Rate Securities for each Interest Period will be determined by the
Calculation Agent. All calculations made by the Calculation Agent shall, in the
absence of manifest error, be conclusive for all purposes and binding on the
Partnership and Holders of the Floating Rate Securities. So long as the
Three-Month LIBOR Rate is required to be determined with respect to the Floating
Rate Securities, there will at all times be a Calculation Agent. In the event
that any then acting Calculation Agent shall be unable or unwilling to act, or
that such Calculation Agent shall fail duly to establish the Three-Month LIBOR
Rate for any Interest Period, or that the Partnership proposes to remove such
Calculation Agent, the Partnership shall appoint another Person which is a bank,
trust company, investment banking firm or other financial institution to act as
the Calculation Agent.

         [The Holder of this Security is entitled to the benefits of the
Registration Rights Agreement. The Partnership agrees to pay additional interest
(the "Additional Interest"), as specified below, upon the occurrence of any of
the following events (each such event an "Additional Interest Event"): (i) if
the Exchange Registration Statement or Shelf Registration Statement is not filed
within 90 days following the Closing Date, then commencing on the 91st day after
the Closing Date, Additional Interest shall accrue on the Securities over and
above the otherwise applicable interest rate at a rate of 0.25% per annum, (ii)
if the Exchange Registration Statement or the Shelf Registration Statement is
filed and is not declared effective within 180 days following the Closing Date,
then commencing on the 181st day after the Closing Date, Additional Interest
shall accrue on the Securities over and above the otherwise applicable interest
rate at a rate of 0.25% per annum, or (iii) if either (A) the Partnership has
not exchanged Exchange Securities of either Series for all Securities of the
same Series validly tendered in accordance with the terms of the Exchange Offer
on or prior to 45 Business Days after the date on which the Exchange
Registration Statement was declared effective, or (B) the Shelf Registration
Statement has been declared effective but such Shelf Registration Statement
ceases to be effective at any time (I) prior to the second anniversary of the
Closing Date or, if Rule 144(k) is amended to provide a shorter restrictive
period, such shorter period (the "Rule 144(k) Holding Period") and (II) while
Registrable Securities are Outstanding, then Additional Interest shall accrue on
the Securities over and above the otherwise applicable interest rate at a rate
of 0.25% per annum commencing on the (x) 46th Business Day after such effective
date, in the case of (A) above, or (y) the day the Shelf Registration Statement
ceases to be effective, in the case of (B) above; provided, however, that the
rate at which Additional Interest accrues on the Securities shall never exceed
0.25% per annum; and provided further that Additional Interest shall cease to
accrue upon the earlier of (X) when all Additional Interest Events have been
cured or (Y) upon the expiration of the Rule 144(k) Holding Period. For purposes
of clarifying the foregoing provisions (i) the circumstances under which
Additional Interest is owed are not cumulative, (ii) in no event will


                                       26
<PAGE>   34


the rate of Additional Interest exceed 0.25% per annum, and (iii) Additional
Interest shall not accrue at any time when there are no Registrable Securities
Outstanding.](3)

         If an Event of Default shall occur and be continuing, the principal of
all the Securities of the Series of which this Security is one may be declared
due and payable in the manner and with the effect provided in the Indenture.

         The Securities of this Series are not redeemable prior to Maturity, and
the Partnership has no obligation to redeem or purchase any Floating Rate
Securities pursuant to any sinking fund or analogous requirement, or (except as
provided in the Indenture) upon the happening of a specified event, or at the
option of the Holder thereof.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Partnership and the rights of Holders of the Securities of each Series under the
Indenture at any time by the Partnership and the Trustee with the consent of a
majority in aggregate principal amount of the Securities of such Series at the
time Outstanding. The Indenture also contains provisions permitting Holders of
specified percentages in aggregate principal amount of the Securities of each
Series at the time Outstanding, on behalf of Holders of all the Securities of
such Series, to waive compliance by the Partnership with certain provisions of
the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Security.

         As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of either Series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to the Securities of such Series,
Holders of not less than 25% in principal amount of the Outstanding Securities
of such Series shall have made written request, and offered reasonable
indemnity, to the Trustee to institute such proceeding as trustee, and the
Trustee shall not have received from Holders of a majority in principal amount
of the Outstanding Securities of such Series a direction inconsistent with such
request and shall have failed to institute such proceedings within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the enforcement of payment of the principal of or any
interest on this Security on or after the respective due dates expressed herein.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall, without the consent of the Holder hereof, alter or
impair the obligation of the Partnership, which is absolute and unconditional,
to pay the principal of and interest on this Security at the times, place and
rate, and in the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Partnership in The City of New York, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Partnership and the Security Registrar duly executed by, the Holder hereof or
its attorney duly authorized in writing, and thereupon one or more new
Securities of this Series and of like tenor, of authorized denominations and for
the same aggregate principal amount, will be issued to the designated transferee
or transferees.

         The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof, unless otherwise
required by law. As provided in the Indenture and subject to certain limitations
therein set forth, Securities of this Series are exchangeable for a like
aggregate principal amount of Securities of this Series of a different
authorized denomination, as requested by the Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Partnership may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

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

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

                  (b) Form of Reverse of Fixed Rate Security.

         This Security is one of a duly authorized issue of securities of the
Partnership, limited in aggregate principal amount to $400,000,000, issued and
to be issued under an Indenture, dated as of March 22, 2000 (herein called the
"Indenture"), between the Partnership and First Union National Bank, as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Partnership, the Trustee and
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered. The Securities issued and to be issued
under the Indenture consist of two Series of Senior Notes ($200,000,000
aggregate original principal amount of Floating Rate Senior Notes due 2002, and
$200,000,000 aggregate original principal amount of 8% Senior Notes due 2005)
and are hereinafter called the "Securities". This Security is one of the Series
of Fixed Rate Securities referred to in the Indenture.

         [The Holder of this Security is entitled to the benefits of the
Registration Rights Agreement. The Partnership agrees to pay additional interest
(the "Additional Interest"), as specified below, upon the occurrence of any of
the following events (each such event an "Additional Interest Event"):

                                       28
<PAGE>   36


(i) if the Exchange Registration Statement or Shelf Registration Statement is
not filed within 90 days following the Closing Date, then commencing on the 91st
day after the Closing Date, Additional Interest shall accrue on the Securities
over and above the otherwise applicable interest rate at a rate of 0.25% per
annum, (ii) if the Exchange Registration Statement or the Shelf Registration
Statement is filed and is not declared effective within 180 days following the
Closing Date, then commencing on the 181st day after the Closing Date,
Additional Interest shall accrue on the Securities over and above the otherwise
applicable interest rate at a rate of 0.25% per annum, or (iii) if either (A)
the Partnership has not exchanged Exchange Securities of either Series for all
Securities of the same Series validly tendered in accordance with the terms of
the Exchange Offer on or prior to 45 Business Days after the date on which the
Exchange Registration Statement was declared effective, or (B) the Shelf
Registration Statement has been declared effective but such Shelf Registration
Statement ceases to be effective at any time (I) prior to the second anniversary
of the Closing Date or, if Rule 144(k) is amended to provide a shorter
restrictive period, such shorter period (the "Rule 144(k) Holding Period") and
(II) while Registrable Securities are Outstanding, then Additional Interest
shall accrue on the Securities over and above the otherwise applicable interest
rate at a rate of 0.25% per annum commencing on the (x) 46th Business Day after
such effective date, in the case of (A) above, or (y) the day the Shelf
Registration Statement ceases to be effective, in the case of (B) above;
provided, however, that the rate at which Additional Interest accrues on the
Securities shall never exceed 0.25% per annum; and provided further that
Additional Interest shall cease to accrue upon the earlier of (X) when all
Additional Interest Events have been cured or (Y) upon the expiration of the
Rule 144(k) Holding Period. For purposes of clarifying the foregoing provisions
(i) the circumstances under which Additional Interest is owed are not
cumulative, (ii) in no event will the rate of Additional Interest exceed 0.25%
per annum, and (iii) Additional Interest shall not accrue at any time when there
are no Registrable Securities Outstanding.](4)

         If an Event of Default shall occur and be continuing, the principal of
all the Securities of the Series of which this Security is one may be declared
due and payable in the manner and with the effect provided in the Indenture.

         The Fixed Rate Securities are redeemable, at the option of the
Partnership, at any time in whole or from time to time in part, upon not less
than 30 and not more than 60 days' notice mailed to each Holder of the Fixed
Rate Securities to be redeemed at the Holder's address appearing in the Security
Register, on any date prior to Maturity at a price equal to (a) 100% of the
principal amount thereof plus accrued interest to the Redemption Date (subject
to the right of holders of record on the relevant Record Date to receive
interest due on an Interest Payment Date that is on or prior to the Redemption
Date) and (b) a Make-Whole Premium, if any (the "Redemption Price"). In no event
will the Redemption Price ever be less than 100% of the principal amount of the
Notes plus accrued interest to the Redemption Date. The Make-Whole Premium will
be calculated by an independent investment banking institution of national
standing appointed by the Partnership; provided, that if the Partnership fails
to make such appointment at least 30 Business Days prior to the Redemption Date,
or if the institution so appointed is unwilling or unable to make such
calculation, such calculation will be made by Goldman, Sachs & Co. or, if such
firm is unwilling or unable to make

such calculation, by an independent investment banking institution of national
standing appointed by the Trustee (in any such case, an "Independent Investment
Banker").

         The Partnership has no obligation to redeem or purchase any Fixed Rate
Securities pursuant to any sinking fund or analogous requirement, or (except as
provided in the Indenture) upon the happening of a specified event, or at the
option of a Holder thereof.

         The Indenture contains provision for defeasance at any time of (1) the
entire indebtedness of this Security or (2) certain covenants contained therein,
in each case upon compliance with certain conditions set forth in the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Partnership and the rights of Holders of the Securities of each Series under the
Indenture at any time by the Partnership and the Trustee with the consent of a
majority in aggregate principal amount of the Securities of such Series at the
time Outstanding. The Indenture also contains provisions permitting Holders of
specified percentages in aggregate principal amount of the Securities of each
Series at the time Outstanding, on behalf of Holders of all the Securities of
such Series, to waive compliance by the Partnership with certain provisions of
the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this
Security and of any Security issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Security.

         As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of either Series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to the Securities of such Series,
Holders of not less than 25% in principal amount of the Outstanding Securities
of such Series shall have made written request, and offered reasonable
indemnity, to the Trustee to institute such proceeding as trustee, and the
Trustee shall not have received from Holders of a majority in principal amount
of the Outstanding Securities of such Series a direction inconsistent with such
request and shall have failed to institute such proceedings within 60 days;
provided, however, that such limitations do not apply to a suit instituted by
the Holder hereof for the enforcement of payment of the principal of or any
interest on this Security on or after the respective due dates expressed herein.

or of the Indenture shall, without the consent of the Holder hereof, alter or
impair the obligation of the Partnership, which is absolute and unconditional,

in respect of principal shall be March 22,



                                       34
<PAGE>   42


2002, and they shall bear interest at a rate per annum calculated as provided in
the Form of Reverse of Floating Rate Security in Section 203(a) hereof, from
March 22, 2000 or from the most recent Interest Payment Date to which interest
has been paid or duly provided for, as the case may be, payable quarterly on
each March 22, June 22, September 22 and December 22, commencing June 22, 2000,
until the principal thereof is paid or made available for payment.

         The aggregate principal amount of Fixed Rate Securities which may be
authenticated and delivered under this Indenture is limited to $200,000,000
Original Fixed Rate Securities and $200,000,000 Fixed Rate Exchange Securities,
except for Fixed Rate Securities authenticated and delivered upon registration
of transfer of, or in exchange for, or in lieu of, other Securities pursuant to
Section 304, 305, 306 or 906.

         The Fixed Rate Securities shall be known and designated as the "8%
Senior Notes due 2005" of the Partnership. Their Stated Maturity in respect of
principal shall be March 15, 2005, and they shall bear interest at the rate of

to which interest has been paid or duly provided for, as the case may be,
payable semi-annually on each March 15 and September 15, commencing September

SECTION 302. Denominations.

         The Securities of each Series shall be issuable only in registered form
without coupons and only denominations of $1,000 and any integral multiple
thereof, unless otherwise required by law.

SECTION 303. Execution, Authentication, Delivery and Dating.

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

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Partnership may deliver Securities of either Series executed
by the Partnership to the Trustee or an Authenticating Agent for authentication,
together with a Partnership Order for the authentication and



                                       35
<PAGE>   43


delivery of such Securities, and the Trustee in accordance with the Partnership
Order shall authenticate and deliver such Securities; provided, however, that
Floating Rate Exchange Securities shall be issuable only upon the valid
surrender for cancellation of Original Floating Rate Securities and Fixed Rate
Exchange Securities shall be issuable only upon the valid surrender for
cancellation of Original Fixed Rate Securities, in each case of a like aggregate
principal amount, in accordance with the Exchange Offer.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or
any Guaranty or be valid or obligatory for any purpose unless there appears on
such Security a certificate of authentication substantially in the form provided
for herein executed by the Trustee by manual signature of an authorized
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. Notwithstanding the foregoing, if any Security shall have
been authenticated and delivered hereunder but never issued and sold by the
Partnership, and the Partnership shall deliver such Security to the Trustee for
cancellation as provided in Section 309 for all purposes of this Indenture, such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

SECTION 304. Temporary Securities.

         Pending the preparation of Definitive Securities of either Series, the
Partnership may execute, and upon receipt of the documents required by Section
303, together with a Partnership Order, the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the Definitive Securities of like Series in lieu
of which they are issued.

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

SECTION 305. Registration, Registration of Transfer and Exchange.

                  (a)      Registration, Registration of Transfer and
                           Exchange, Generally.

         The Partnership shall cause to be kept at an office or agency of the
Security Registrar in The City of New York a register (the register maintained
in such office or in any other office or agency of the Partnership in a Place of
Payment being herein sometimes referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Partnership
shall provide for the registration of Securities and of transfers of Securities.
The Partnership shall, prior to the issuance of any Securities hereunder,
appoint the Trustee as the initial "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided and its
corporate trust office which, at the date hereof, is located at 40 Broad Street,
Suite 550, New York, New York 10004, as the initial office or agency in The City
of New York where the Security Register will be maintained. The Partnership may
at any time replace such Security Registrar, change such office or agency or act
as its own Security Registrar. The Partnership will give prompt written notice
to the Trustee of any change of the Security Registrar or of the location of
such office or agency. At all reasonable times the Security Register shall be
available for inspection by the Trustee.

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

         At the option of the Holder, Securities of either Series (except a
Global Security) may be exchanged for other Securities of the same Series, of
any authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Partnership shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive; provided that no exchange
of Original Floating Rate Securities or of Original Fixed Rate Securities for
Exchange Securities of the same Series shall occur until a registration
statement for the issuance of the Exchange Securities shall have been declared
effective by the Commission and the Original Floating Rate Securities and the
Original Fixed Rate Securities to be exchanged for such Exchange Securities
shall be cancelled by the Trustee.

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

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

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Partnership may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304 or 1107 not involving any transfer.



                                       37

         Neither the Trustee nor the Partnership shall be required (1) to issue,
register the transfer of or exchange Fixed Rate Securities during a period
beginning at the opening of business 15 days before the day of mailing of a
notice of redemption of Fixed Rate Securities selected for redemption under
Section 1103 and ending at the close of business on the day of such mailing, or
(2) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

         The provisions of Clauses (1), (2), (3) and (4) below shall apply only
to Global Securities:

                  (1) Each Global Security authenticated under this Indenture
shall be registered in the name of the Depositary designated for such Global
Security or a nominee thereof and delivered to such Depositary or a nominee
thereof or custodian therefor, and each such Global Security shall constitute a
single Security for all purposes of this Indenture.

                  (2) Notwithstanding any other provision in this Indenture, no
Global Security may be exchanged in whole or in part for Securities registered,
and no transfer of a Global Security in whole or in part may be registered, in
the name of any Person other than the Depositary for such Global Security or a
nominee thereof unless (A) such Depositary (i) has notified the Partnership that
it is unwilling or unable to continue as Depositary for such Global Security or
(ii) has ceased to be a clearing agency registered under the Exchange Act, and
in either (i) or (ii) of this clause (2) a successor Depositary is not appointed
by the Partnership within 90 days after the date of such notice from the
Depositary, (B) there shall have occurred and be continuing a Default or an
Event of Default, or (C) the Partnership by Partnership Order, elects to have
the Global Security registered in the name of a Person other than the Depositary
or its nominee.

                  (3) Subject to Clause (2) above, any exchange of a Global
Security for other Securities of the same Series may be made in whole or in
part, and all Securities issued in exchange for a Global Security or any portion
thereof shall be registered in such names as the Depositary for such Global
Security shall direct.

                  (4) Every Security authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global Security
or any portion thereof, whether pursuant to this Section, Section 304, 306 or
906 or otherwise, shall be authenticated and delivered in the form of, and shall
be, a Global Security, unless such Security is registered in the name of a
Person other than the Depositary for such Global Security or a nominee thereof.

                  (b) Certain Transfers and Exchanges. Notwithstanding any other
provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified
in this Section 305(b) shall be made only in accordance with this Section
305(b).

                           (i) Restricted Global Security to Regulation S Global
         Security. If the owner of a beneficial interest in a Restricted Global
         Security wishes at any time to transfer such interest to a Person who
         wishes to acquire the same in the form of a beneficial interest in the
         Regulation S Global Security of the same Series, such transfer may be
         effected only

         in accordance with the provisions of this Clause (b)(i) and Clause
         (b)(iv) below and subject to the Applicable Procedures. Upon receipt by
         the Trustee, as Security Registrar, of (A) an order given by the
         Depositary or its authorized representative directing that a beneficial
         interest in the Regulation S Global Security in a specified principal
         amount be credited to a specified Agent Member's account and that a
         beneficial interest in the Restricted Global Security of the same
         Series and in an equal principal amount be debited from another
         specified Agent Member's account and (B) a Regulation S Certificate,
         satisfactory to the Trustee and duly executed by the owner of such
         beneficial interest in the Restricted Global Security or his attorney
         duly authorized in writing, then the Trustee, as Security Registrar but
         subject to Clause (b)(iv) below, shall reduce the principal amount of
         the Restricted Global Security and increase the principal amount of the
         Regulation S Global Security of the same Series by such specified
         principal amount.

                           (ii) Regulation S Global Security to Restricted
         Global Security. If the owner of a beneficial interest in a Regulation
         S Global Security wishes at any time to transfer such interest to a
         Person who wishes to acquire the same in the form of a beneficial
         interest in the Restricted Global Security of the same Series, such
         transfer may be effected only
         in accordance with this Clause (b)(ii) and subject to the Applicable
         Procedures. Upon receipt by the Trustee, as Security Registrar, of (A)
         an order given by the Depositary or its authorized representative
         directing that a beneficial interest in the Restricted Global Security
         in a specified principal amount be credited to a specified Agent
         Member's account and that a beneficial interest in the Regulation S
         Global Security of the same Series and in an equal principal amount be
         debited from another specified Agent Member's account and (B) if such
         transfer is to occur during the Restricted Period, a Restricted
         Securities Certificate, satisfactory to the Trustee and duly executed
         by the owner of such beneficial interest in the Regulation S Global
         Security or his attorney duly authorized in writing, then the Trustee,
         as Security Registrar, shall reduce the principal amount of the
         Restricted Global Security of the same Series by such specified
         principal amount. If transfers under this Clause (b)(ii) occur after
         the Restricted Period, no Restricted Securities Certificates will be
         required.

                           (iii) Non-Global Security to Non-Global Security. A
         Security that is not a Global Security may be transferred, in whole or
         in part to a Person who takes delivery in the form of another Security
         of the same Series that is not a Global Security as provided in Section
         305(a), provided, that, if the Security to be transferred in whole or
         in part is a Restricted Security, then the Trustee shall have received
         a Restricted Securities Certificate, satisfactory to the Trustee and
         duly executed by the transferor Holder or his attorney duly authorized
         in writing, in which case the Transferee Holder shall take delivery in
         the form of a Restricted Security (subject in every case to Section
         305(c)).

                           (iv) Regulation S Global Security to be Held Through
         Euroclear or Cedel During Restricted Period. The Partnership shall use
         its reasonable efforts to cause the Depositary to ensure that during
         the Restricted Period beneficial interests in a Regulation S Global
         Security may be held only in or through accounts maintained at the
         Depositary by Euroclear or Cedel (or by Agent Members acting for the
         account thereof), and no Person shall be entitled to effect any
         transfer or exchange that would result in any such interest being



                                       39
<PAGE>   47


         held otherwise than in or through such an account; provided, that this
         Clause (b)(iv) shall not prohibit any transfer or exchange of such an
         interest in accordance with Clause (b)(ii) above.

                           (v) Restricted Non-Global Security to Restricted
         Global Security or Regulation S Global Security. If the Holder of a
         Restricted Security (other than a Global Security) wishes at any time
         to transfer all or any portion of such Security to a Person who wishes
         to take delivery thereof in the form of a beneficial interest in the
         Restricted Global Security of the same Series or the Regulation S
         Global Security of the same Series, such transfer may be effected only
         in accordance with the provisions of this Clause (b)(v) and Clause
         (b)(iv) above and subject to the Applicable Procedures. Upon receipt by
         the Trustee, as Security Registrar, of (A) such Security as provided in
         Section 305(a) and instructions satisfactory to the Trustee directing
         that a beneficial interest in such Restricted Global Security of the
         same Series or such Regulation S Global Security of the same Series in
         a specified principal amount not greater than the principal amount of
         such Security be credited to a specified Agent Member's account and (B)
         a Restricted Securities Certificate, if the specified account is to be
         credited with a beneficial interest in such Restricted Global Security,
         or a Regulation S Certificate, if the specified account is to be
         credited with a beneficial interest in such Regulation S Global
         Security of the same Series, in either case satisfactory to the Trustee
         and duly executed by such Holder or his attorney duly authorized in
         writing, then the Trustee, as Security Registrar, shall cancel such
         Security (and issue a new Security in respect of any untransferred
         portion thereof) and increase the principal amount of the Restricted
         Global Security of the same Series or the Regulation S Global Security
         of the same Series, as the case may be, by the specified principal
         amount, both as provided in Section 305(a).

                  (c) Securities Act Legends. Restricted Securities and their
Successor Securities shall bear a Restricted Securities Legend, and the
Regulation S Securities and their Successor Securities shall bear a Regulation S
Legend, subject to the following:

                           (i) subject to the following Clauses of this Section
         305(c), a Security or any portion thereof which is exchanged, upon
         transfer or otherwise, for a Global Security of the same Series or any
         portion thereof shall bear the Securities Act Legend borne by such
         Global Security while represented thereby;

                           (ii) subject to the following Clauses of this Section
         305(c), a new Security which is not a Global Security and is issued in
         exchange for another Security of the same Series (including a Global
         Security of the same Series or any portion thereof, upon transfer or
         otherwise, shall bear the Securities Act Legend borne by such other
         Security, provided that, if such new Security is required pursuant to
         Section 305(b)(v) to be issued in the form of a Restricted Security, it
         shall bear a Restricted Securities Legend and, if such new Security is
         so required to be issued in the form of a Regulation S Security, it
         shall bear a Regulation S Legend;



                                       40
<PAGE>   48


                           (iii) Registered Securities shall not bear a
         Securities Act Legend;


                           (iv) at any time after the Securities may be freely
         transferred without registration under the Securities Act or without
         being subject to transfer restrictions pursuant to the Securities Act,
         a new Security which does not bear a Securities Act legend may be
         issued in exchange for or in lieu of a Security of the same Series
         (other than a Global Security) or any portion thereof which bears such
         a legend if the Trustee has received an Unrestricted Securities
         Certificate, satisfactory to the Trustee and duly executed by the
         Holder of such legended Security or his attorney duly authorized in
         writing, and after such date and receipt of such certificate, the
         Trustee shall authenticate and deliver such a new Security in exchange
         for or in lieu of such other Security as provided in this Article
         Three.

                           (v) a new Security which does not bear a Securities
         Act Legend may be issued in exchange for or in lieu of a Security of
         the same Series (other than a Global Security) or any portion thereof
         which bears such a legend if, in the Partnership's judgment, placing
         such a legend upon such new Security is not necessary to ensure
         compliance with the registration requirements of the Securities Act,
         and the Trustee, at the written direction of the Partnership, shall
         authenticate and deliver such a new Security as provided in this
         Article Three; and

                           (vi) notwithstanding the foregoing provisions of this
         Section 305(c), a Successor Security of a Security that does not bear a
         particular form of Securities Act Legend shall not bear such form of
         legend unless the Partnership has reasonable cause to believe that such
         Successor Security is a "restricted security" within the meaning of
         Rule 144, in which case the Trustee, at the written direction of the
         Partnership, shall authenticate and deliver a new Security bearing a
         Restricted Securities Legend in exchange for such Successor Security as
         provided in this Article Three.

         Furthermore, any Holder of a Global Security shall, by acceptance of
such Global Security, agree that transfers of beneficial interests in such
Global Security may be effected only through a book-entry system maintained by
the Holder of such Global Security (or its agent), and that ownership of a
beneficial interest in such Global Security shall be required to be reflected in
a book entry.

         The Trustee shall retain copies of all letters, notices and other
written communications (if any) received concerning transfer or exchange, and
the Partnership shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the
giving of a reasonable written notice to the Trustee.

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

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


                                       41

<PAGE>   49


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

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

         Upon the issuance of any new Security under this Section, the
Partnership may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Every new Security of either Series issued pursuant to this Section in exchange
for any mutilated Security or in lieu of any destroyed, lost or stolen Security
shall constitute an original additional contractual obligation of the
Partnership, whether or not the mutilated, destroyed, lost or stolen Security
shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Securities of that Series duly issued hereunder.

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

SECTION 307. Payment of Interest; Interest Rights Preserved.

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

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

                                       42
<PAGE>   50

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

                  (2) The Partnership may make payment of any Defaulted Interest
on the Securities of either Series in any other lawful manner not inconsistent
with the requirements of either securities exchange or automated quotation
system on which such Securities may be listed or traded, and upon such notice as
may be required by such exchange, if, after notice given by the Partnership to
the Trustee of the proposed payment pursuant to this Clause, such manner of
payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security, shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         For each Series of Securities, the Partnership shall, prior to 10:30
a.m. (New York City time) on each payment date for principal and premium, if
any, and interest, if any, deposit with the Trustee money in immediately
available funds sufficient to make cash payments due on the applicable payment
date.

SECTION 308. Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Partnership, the Trustee and any agent of the Partnership or the Trustee may
treat the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and


                                       43
<PAGE>   51

any premium and (subject to Sections 305 and 307) any interest on such Security
and for all other purposes whatsoever, whether or not such Security is overdue,
and neither the Partnership, the Trustee nor any agent of the Partnership or the
Trustee shall be affected by notice to the contrary.

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

SECTION 309. Cancellation.

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

SECTION 310. Computation of Interest.

         Interest on the Fixed Rate Securities shall be computed on the basis of
a 360-day year of twelve 30-day months and interest on the Securities of such
Series for any partial period shall be computed on the basis of a 360-day year
of twelve 30-day months and the number of days elapsed in any partial month.
Interest on the Floating Rate Securities shall be computed on the basis set
forth in the Form of Reverse of Floating Rate Security in Section 203(a).

SECTION 311. CUSIP Numbers.

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

SECTION 401. Satisfaction and Discharge of Indenture.

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

                  (1) either

                           (A) all such Securities theretofore authenticated and
         delivered (other than (i) such Securities which have been destroyed,
         lost or stolen and which have been replaced or paid as provided in
         Section 306, and (ii) such Securities for whose payment money has
         theretofore been deposited in trust or segregated and held in trust by
         the Partnership and thereafter repaid to the Partnership or discharged
         from such trust, as provided in Section 1003) have been delivered to
         the Trustee for cancellation; or

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

                           (i) have become due and payable,

                           (ii) will become due and payable at their Stated
         Maturity in respect of principal within one year (in the case of the
         Fixed Rate Securities), or at the end of the then current Interest
         Period (in the case of the Floating Rate Securities), or

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

and the Partnership in the case of (i), (ii) or (iii) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust for
this purpose an amount in Dollars sufficient to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for
cancellation, for principal and any premium and interest to the date of such
deposit (in the case of Securities which have become due and payable) or to the
Stated Maturity of the principal thereof, or, in the case of the Fixed Rate
Securities, the Redemption Date, as the case may be;

                  (2) the Partnership has paid or caused to be paid all other
sums payable hereunder by the Partnership with respect to such Securities; and

Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this
Indenture with respect to such Securities have been complied with.

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

SECTION 402. Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Partnership acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                    REMEDIES

SECTION 501. Events of Default.

         "Event of Default", wherever used herein with respect to Securities of
either Series, means any one of the following events (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be

court or any order, rule or regulation of any administrative or governmental
body):

of that Series when it becomes due and payable, and continuance of such default
for a period of 30 days; or

                  (2) default in the payment of the principal of (or premium, if
any, on) any Security of that Series at its Maturity; or

                  (3) default in the performance, or breach, of any term,
covenant or warranty of the Partnership or any Guarantor in this Indenture or
the applicable Guaranty, 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 or such Guarantor by the Trustee or to the Partnership or such
Guarantor and the Trustee by 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

Partnership; and the order or decree remains unstayed and in effect for 90 days.

SECTION 502. Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to Securities of either Series at
the time Outstanding occurs and is continuing, then in every such case the
Trustee or Holders of not less than 25% in principal amount of the Outstanding
Securities of that Series may declare the principal amount of and accrued but
unpaid interest, if any, on all of the Securities of that Series to be due and
payable immediately, by a notice in writing to the Partnership (and to the
Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of either 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, Holders of a majority in principal amount of the Outstanding
Securities of that Series, by written notice to the Partnership and the Trustee,
may rescind and annul such declaration and its consequences if

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

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

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

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

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

and

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


                                       47
<PAGE>   55

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

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

         The Partnership covenants that if

                  (1) default is made in the payment of any interest on any
Security when such interest becomes due and payable and such default continues
for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
premium, if any, on) any Security at the Maturity thereof,

the Partnership will, upon demand of the Trustee, pay to it, for the benefit of
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If the Partnership fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Partnership, any Guarantor, or any other obligor
upon such Securities and collect the moneys adjudged or decreed to be payable in
the manner provided by law out of the property of the Partnership, any
Guarantor, or any other obligor upon such Securities, wherever situated.

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

SECTION 504. Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Partnership, any
Guarantor, or any other obligor upon the Securities, their property or their
creditors, the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act in order to have claims of Holders and the Trustee allowed in any
such proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial


                                       48
<PAGE>   56


proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

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

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

SECTION 506. Application of Money Collected.

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

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

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

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

SECTION 507. Limitation on Suits.

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


                                       49
<PAGE>   57

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

                  (3) such Holder or Holders have offered and, if requested,
provided to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities to be incurred in compliance with such request;

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and
             Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Sections 305
and 307) interest on such Security on the respective Stated Maturities expressed
in such Security (or, with respect to the Fixed Rate Securities, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

SECTION 509. Restoration of Rights and Remedies.

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


                                       50
<PAGE>   58


SECTION 510. Rights and Remedies Cumulative.

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

SECTION 511. Delay or Omission Not Waiver.

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

SECTION 512. Control by Holders.

         Subject to the provisions of Section 603, Holders of a majority in
aggregate principal amount of the Outstanding Securities of either Series shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee, with respect to the Securities of such Series;
provided, however, that

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

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

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

SECTION 513. Waiver of Past Defaults.

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

                  (1) a continuing default in the payment of the principal of or
any premium or interest on any Security of such Series, or


                                       51
<PAGE>   59

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

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

SECTION 514. Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, however, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Trustee,
in 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
either Series to which the suit relates, or in any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security on or after the respective Stated Maturities expressed
by such Security (or, with respect to the Fixed Rate Securities, in the case of
redemption or repayment, on or after the Redemption Date).

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

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

                                   ARTICLE VI

                                   THE TRUSTEE

SECTION 601. Certain Duties and Responsibilities.

                  (a) Except during the continuance of an Event of Default with
respect to either Series of Securities,

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


                                       52
<PAGE>   60

                  (2) in the absence of bad faith on its part, the Trustee may,
with respect to Securities of such Series, 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 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.

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

                  (c) No provisions 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 or a majority in principal amount of the Outstanding
Securities of either 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.

<PAGE>   61

SECTION 602. Notice of Defaults.

         If a Default occurs and is continuing with respect to the Securities of
either Series, the Trustee shall, within 90 days after it occurs, transmit, in
the manner and to the extent provided in Section 313(c) of the Trust Indenture
Act, notice of all uncured or unwaived Defaults known to it; provided, however,
that, except in the case of a Default in payment on the Securities of either
Series, the Trustee shall be protected in withholding the notice if and so long
as the board of directors, the executive committee or a trust committee of
directors or responsible officers of the Trustee determine in good faith that
withholding such notice is in the interests of Holders of Securities of such
Series; provided, further, however, that, in the case of any Default of the
character specified in Section 501(3) with respect to the Securities of such
Series, no such notice to Holders shall be given until at least 30 days after
the occurrence of such Default.

SECTION 603. Certain Rights of Trustee.

         Subject to the provisions of Section 601:

                  (1) the Trustee may rely on and shall be protected in acting
or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

                  (2) any request, direction, order or demand of the Partnership
mentioned herein shall be sufficiently evidenced by a Partnership Request or
Partnership Order and any resolution of the Board of Directors shall be
sufficiently evidenced by a Board Resolution;

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

                  (4) the Trustee may consult with counsel and the written
advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

                  (5) the Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Indenture at the request or
direction of any Holders pursuant to this Indenture, unless such Holders shall
have offered to the Trustee security or indemnity satisfactory to it against the
costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction;

                  (6) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,

debenture, note, other evidence of indebtedness or other paper or


                                       54
<PAGE>   62

document, but 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,
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;

                  (8) the Trustee is not a party to the Registration Rights
Agreement and shall be entitled to rely on an Officers' Certificate as to
whether Additional Interest is owed on the Securities; and

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

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

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Partnership, and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. Neither the Trustee nor any Authenticating
Agent makes any representations as to the validity or sufficiency of this
Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent
shall be accountable for the use or application by the Partnership of the
Securities or the proceeds thereof.

SECTION 605. May Hold Securities.

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

SECTION 606. Money Held in Trust.

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


                                       55
<PAGE>   63

SECTION 607. Compensation and Reimbursement.

         The Partnership agrees:

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

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

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

                  (4) The Trustee shall have a claim prior to the Securities as
to all property and funds held by it hereunder for any amounts owing it or any
predecessor Trustee pursuant to this Section 607, except to funds held in trust
for the benefit of Holders of any Securities.

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

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

         The provisions of this Section 607 and the obligations of the
Partnership thereunder, shall survive payment in full of the Securities, the
satisfaction and discharge of this Indenture and any defeasance of the Fixed
Rate Securities.

SECTION 608. Disqualification; Conflicting Interests.

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

<PAGE>   64

SECTION 609. Corporate Trustee Required; Eligibility.

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

SECTION 610. Resignation and Removal; Appointment of Successor.

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

         The Trustee may resign at any time by giving written notice thereof to
the Partnership. If the instrument of acceptance by a successor Trustee required
by Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

         The Trustee may be removed at any time by Act of Holders of a majority
in principal amount of the Outstanding Securities of each Series, delivered to
the Trustee and 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 removal, the removed Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

         If at any time:

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

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

                  (3) the Trustee shall become incapable of acting or shall be
adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property
shall be appointed or any public officer shall take charge or control of the
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case (A) the Partnership, by a
Board Resolution, may remove the Trustee, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee.

         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, the
Partnership, by a Board Resolution, shall promptly appoint a successor Trustee
and shall comply with the applicable requirements of Section 611. If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee shall be appointed by Act of Holders of a majority
in principal amount of the Outstanding Securities of each Series delivered to
the Partnership and the retiring Trustee, the successor Trustee so appointed
shall, forthwith upon its acceptance of such appointment in accordance with the
applicable requirements of Section 611, become the successor Trustee and shall
supersede the successor Trustee appointed by the Partnership. If no successor
Trustee shall have been so appointed by the Partnership or Holders and accepted
appointment in the manner required by Section 611, any Holder 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 situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee.

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

SECTION 611. Acceptance of Appointment by Successor.

                  (1) Every such successor Trustee appointed hereunder shall
execute, acknowledge and deliver to the Partnership and to the retiring Trustee
an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee; but, on the
request of the Partnership or the successor Trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

                  (2) Upon request of any such successor Trustee, the
Partnership shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts referred to in paragraph (1) of this Section.

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

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

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or


                                       58
<PAGE>   66

filing of any paper or any further act on the part of any of the parties hereto.
In case any Securities shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

SECTION 613. Preferential Collection of Claims Against Partnership.

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

SECTION 614. Appointment of Authenticating Agent.

         The Trustee (upon notice to the Partnership) may appoint an
Authenticating Agent or Agents which shall be authorized to act on behalf of the
Trustee to authenticate Securities issued upon original issue and upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section
306, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Partnership and shall at all times be a corporation organized and doing business
under the laws of the United States, any State thereof or the District of
Columbia, authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to
the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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


                                       59
<PAGE>   67

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

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

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

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

SECTION 702. Preservation of Information; Communications to Holders.

         The Trustee shall preserve, in as current a form as is reasonably

addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

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

         Every Holder of Securities, by receiving and holding the same, agrees
with the Partnership and the Trustee that neither the Partnership nor the
Trustee nor any agent of either of them shall be held accountable by reason of
any disclosure of information as to the names and addresses of Holders made
pursuant to the Trust Indenture Act.

         As promptly as practicable after each May 15 beginning with the May 15

that complies with TIA Section 313(a). The Trustee also shall comply with TIA
Section 313(b). Prior to delivery to Holders, the Trustee shall deliver to the
Partnership a copy of any report it delivers to Holders pursuant to this Section
703.

         A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Partnership. The
Partnership will notify the Trustee when any Securities are listed on any stock

properties and assets as, or substantially as, an entirety to, any Person,
unless:

                  (1) (A) in the case of a merger, the Partnership or such
Guarantor, as the case may be, is the surviving entity, or (B) the Person formed
by such consolidation or into which the Partnership or such Guarantor is merged
or the Person which acquires by sale or transfer, or which leases, the

as, an entirety must expressly assume, by an indenture supplemental hereto, or a
supplement to the applicable Guaranty, as the case may be, executed and
delivered to the Trustee, in form reasonably

succeed to, and be substituted for, and may exercise every right and power of,
the Partnership or such Guarantor under this Indenture and the Securities, or
the Guaranty of such Guarantor, as the case may be, with the same effect as if

Indenture cannot be modified or waived without the consent of the Holder of each
Outstanding Security affected thereby.

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

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

SECTION 903. Execution of Supplemental Indentures.

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

SECTION 906. Reference in Securities to Supplemental Indentures.

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

SECTION 1001. Payment of Principal, Premium and Interest.

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

SECTION 1002. Maintenance of Office or Agency.

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

         The Partnership may also from time to time designate one or more other
offices or agencies in the City of New York where the Securities of either or
both Series may be presented or surrendered for any or all such purposes and may
from time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Partnership of its
obligation to maintain an office or agency in the Place of Payment 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.

         The Partnership hereby permanently designates as the Place of Payment
for each Series of Securities The City of New York, and initially appoints the
Trustee as Paying Agent at its office located at 40 Broad Street, Suite 550, New
York, New York 10004, as the Partnership's office or agency for such purpose in
such city.

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

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

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

         The Partnership will cause each Paying Agent for either Series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (1) hold all sums
held by it for the payment of the principal of (and premium, if any) or
interest, if any, on Securities of that Series in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or
otherwise disposed of as herein provided; (2) give the Trustee notice of any
default by the Partnership or any Guarantor (or any other obligor upon the
Securities of that Series) in the making of any payment of principal (and
premium, if any) or interest, if any, on the Securities of that Series; and (3)
during the continuance of any such default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent for payment in respect of the Securities of that Series.

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

         Any money deposited with the Trustee or any Paying Agent in trust for
the payment of the principal of or any premium or interest on any Security and
remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the state whose escheat laws control,
and the Trustee or such Paying Agent shall be discharged from such trust; and
the Holder of such Security shall thereafter, as an unsecured general creditor,
look only to the state whose escheat laws control, 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
payment, 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


                                       67
<PAGE>   75

be less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will be paid to the state whose escheat laws control.

SECTION 1004. Statement by Officers as to Default.

         The Partnership will deliver to the Trustee, within 150 days after the
end of each fiscal year of the Partnership ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof the Partnership or any Guarantor is in default in the
performance and observance of any of the terms, provisions and conditions of
this Indenture (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Partnership or any Guarantor shall be in
default, specifying all such defaults and the nature and status thereof of which
they may have knowledge.

SECTION 1005. Existence.

         Subject to Article VIII, the Partnership will do or cause to be done
all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and franchises and those of each
Guarantor; provided, however, that neither the Partnership nor any Guarantor
shall be required to preserve any such right or franchise if the Partnership
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Partnership or such Guarantor.

SECTION 1006. Limitations on Liens.

         The Partnership will not, nor will it permit any Subsidiary to, create,
assume, incur or suffer to exist any Lien upon any Principal Property, or upon
any shares of capital stock of any Subsidiary owning or leasing any Principal
Property, whether owned or leased on the date of this Indenture or thereafter
acquired, to secure any Debt of the Partnership or any other Person (other than
the Securities issued hereunder), without in any such case making effective
provision whereby all of the Securities Outstanding hereunder shall be secured
equally and ratably with, or prior to, such Debt so long as such Debt shall be
so secured. This restriction shall not apply to:

                  (1) Permitted Liens;

                  (2) any Lien upon any property or assets created at the time
of acquisition of such property or assets by the Partnership or any Subsidiary
or within one year after such time to secure all or a portion of the purchase
price for such property or assets or Debt incurred to finance such purchase
price, whether such Debt was incurred prior to, at the time of or within one
year after the date of such acquisition;

                  (3) any Lien upon any property or assets to secure all or part
of the cost of construction, development, repair or improvements thereon or to
secure Debt incurred prior to, at the time of, or within one year after
completion of such construction, development, repair or improvements or the
commencement of full operations thereof (whichever is later), to provide funds
for any such purpose;


                                       68
<PAGE>   76

                  (4) any Lien upon any property or assets existing thereon at
the time of the acquisition thereof by the Partnership or any Subsidiary
(whether or not the obligations secured thereby are assumed by the Partnership
or any Subsidiary); provided, however, that such Lien only encumbers the
property or assets so acquired;

                  (5) any Lien upon any property or assets of a Person existing
thereon at the time such Person becomes a Subsidiary by acquisition, merger or
otherwise; provided, however, that such Lien only encumbers the property or
assets of such Person at the time such Person becomes a Subsidiary;

                  (6) any Lien upon any property or assets of the Partnership or
any Subsidiary in existence on the Closing Date or provided for pursuant to
agreements existing on the Closing Date;

                  (7) Liens imposed by law or order as a result of any
proceeding before any court or regulatory body that is being contested in good
faith, and Liens which secure a judgment or other court-ordered award or
settlement as to which the Partnership or the applicable Subsidiary, as the case
may be, has not exhausted its appellate rights;

                  (8) any extension, renewal, refinancing, refunding or
replacement (or successive extensions, renewals, refinancing, refunding or
replacements) of Liens, in whole or in part, referred to in Clauses (1) through
(7), inclusive, of this Section; provided, however, that any such extension,
renewal, refinancing, refunding or replacement Lien shall be limited to the
property or assets covered by the Lien extended, renewed, refinanced, refunded
or replaced and that the obligations secured by any such extension, renewal,
refinancing, refunding or replacement Lien shall be in an amount not greater
than the amount of the obligations secured by the Lien extended, renewed,
refinanced, refunded or replaced and any expenses of the Partnership and its
Subsidiaries (including any premium) incurred in connection with such extension,
renewal, refinancing, refunding or replacement; or

                  (9) any Lien resulting from the deposit of moneys or evidence
of indebtedness in trust for the purpose of defeasing Debt of the Partnership or
any Subsidiary.

         Notwithstanding the foregoing provisions of this Section, the
Partnership may, and may permit any Subsidiary to, create, assume, incur or
suffer to exist any Lien upon any Principal Property to secure Debt of the
Partnership or any Person (other than the Securities) that is not excepted by
Clauses (1) through (9), inclusive, of this Section without securing the
Securities issued hereunder, provided that the aggregate principal amount of all
Debt then outstanding secured by such Lien and all similar Liens, together with
all Attributable Indebtedness from Sale-Leaseback Transactions (excluding
Sale-Leaseback Transactions permitted by Clauses (1) through (4), inclusive, of
Section 1007), does not exceed 10% of Consolidated Net Tangible Assets.


                                       69
<PAGE>   77

SECTION 1007. Restriction of Sale-Leaseback Transaction.

         The Partnership will not, and will not permit any Subsidiary to, engage
in a Sale-Leaseback Transaction, unless:

                  (1) such Sale-Leaseback Transaction occurs within one year
from the date of completion of the acquisition of the Principal Property subject
thereto or the date of the completion of construction, development or
substantial repair or improvement, or commencement of full operations on such
Principal Property, whichever is later;

                  (2) the Sale-Leaseback Transaction involves a lease for a
period, including renewals, of not more than three years;

                  (3) the Partnership or such Subsidiary would be entitled to
incur Debt secured by a Lien on the Principal Property subject thereto in a
principal amount equal to or exceeding the Attributable Indebtedness from such
Sale-Leaseback Transaction without equally and ratably securing the Securities;
or
                  (4) the Partnership or such Subsidiary, within a one-year
period after such Sale-Leaseback Transaction, applies or causes to be applied
an amount not less than the Attributable Indebtedness from such Sale-Leaseback
Transaction to (A) the prepayment, repayment, redemption, reduction or
retirement of Pari Passu Debt of the Partnership or any Subsidiary, or (B) the
expenditure or expenditures for Principal Property used or to be used in the
ordinary course of business of the Partnership or its Subsidiaries.

         Notwithstanding the foregoing provisions of this Section, the
Partnership may, and may permit any Subsidiary to, effect any Sale-Leaseback
Transaction that is not excepted by Clauses (1) through (4), inclusive, of this
Section, provided that the Attributable Indebtedness from such Sale-Leaseback
Transaction, together with the aggregate principal amount of then outstanding
Debt (other than the Securities) secured by Liens upon Principal Properties not
excepted by Clauses (1) through (9), inclusive, of Section 1006, do not exceed
10% of the Consolidated Net Tangible Assets.

SECTION 1008. Waiver of Certain Covenants.

         The Partnership may omit in any particular instance to comply with any
term, provision or condition set forth in Section 1005, 1006 or 1007 with
respect to the Securities of either Series if before the time for such
compliance Holders of at least a majority in aggregate principal amount of the
Outstanding Securities such Series shall, by Act of such Holders, either waive
such compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Partnership and the
Guarantors and the duties of the Trustee in respect of any such term, provision
or condition shall remain in full force and effect.


                                       70
<PAGE>   78

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

SECTION 1009. Officers' Certificate as to Additional Interest.

         The Partnership shall deliver an Officers' Certificate to the Trustee
within five Business Days after an Additional Interest Event occurs which
identifies such Additional Interest Event and states the date as of which
Additional Interest began accruing or will begin to accrue. Promptly upon (i) an
Additional Interest Event having been cured or (ii) the expiration of the Rule
144(k) Holding Period, the Partnership shall deliver to the Trustee an Officers'
Certificate which identifies such Additional Interest Event, states that it has
been cured or that the Rule 144(k) Holding Period has expired, as the case may
be, and states the date as of which Additional Interest ceased accruing or will
cease to accrue.

                                   ARTICLE XI

                       REDEMPTION OF FIXED RATE SECURITIES

SECTION 1101. Optional Redemption.

         The Fixed Rate Securities will be redeemable, at the option of the
Partnership, at any time in whole or from time to time in part, upon not less
than 30 and not more than 60 days' notice mailed to each Holder of the Fixed
Rate Securities to be redeemed at the Holder's address appearing in the Security
Register, on any date prior to Maturity at a price equal to (a) 100% of the
principal amount thereof plus accrued interest to the Redemption Date (subject
to the right of holders of record on the relevant Record Date to receive
interest due on an Interest Payment Date that is on or prior to the Redemption
Date) and (b) a Make-Whole Premium, if any (the "Redemption Price"). In no event
will the Redemption Price ever be less than 100% of the principal amount of the
Notes plus accrued interest to the Redemption Date. The Make-Whole Premium will
be calculated by an independent investment banking institution of national
standing appointed by the Partnership; provided, that if the Partnership fails
to make such appointment at least 30 business days prior to the Redemption Date,
or if the institution so appointed is unwilling or unable to make such
calculation, such calculation will be made by Goldman, Sachs & Co. or, if such
firm is unwilling or unable to make such calculation, by an independent
investment banking institution of national standing appointed by the Trustee (in
any such case, an "Independent Investment Banker").

         The Partnership has no obligation to redeem or purchase any Securities
pursuant to any sinking fund or analogous requirement, or (except as provided in
Article V) upon the happening of a specified event, or at the option of a Holder
thereof.


                                       71
<PAGE>   79

SECTION 1102. Election to Redeem; Notice to Trustee.

         The election of the Partnership to redeem any Fixed Rate Securities
shall be evidenced by a Board Resolution. In case of any redemption at the
election of the Partnership of less than all the Securities of such Series, the
Partnership shall, not less than 35 nor more than 60 days prior to the
Redemption Date fixed by the Partnership (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the
principal amount of Securities of such Series to be redeemed.

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

         If less than all the Fixed Rate Securities are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such Series not previously called for redemption, on a pro rata basis or by any
other method which the Trustee deems fair and appropriate and which complies
with any securities exchange or other applicable requirements for redemption of
portions (equal to the minimum authorized denomination for Securities of that
Series or any integral multiple thereof) of the principal amount of Securities
of such Series of a denomination larger than the minimum authorized denomination
for Securities of that Series.

         The Trustee shall promptly notify the Partnership in writing of the
Fixed Rate Securities selected for redemption and, in the case of any such
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 the Fixed Rate Securities
shall relate, in the case of any such Securities redeemed or to be redeemed only
in part, to the portion of the principal amount of such Securities which has
been or is to be redeemed.

SECTION 1104. Notice of Redemption.

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

         All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price,

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


                                       72
<PAGE>   80

                  (4) that on the Redemption Date the Redemption Price will
become due and payable upon each such Security to be redeemed and that interest
thereon will cease to accrue on and after said date, and

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

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

SECTION 1105. Deposit of Redemption Price.

         On or prior to 10:30 a.m. New York City Time on any Redemption Date,
the Partnership shall deposit with the Trustee or with a Paying Agent (or, if
the Partnership is acting as its own Paying Agent, segregate and hold in trust
as provided in Section 1003) an amount of money sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Fixed Rate Securities which are to be redeemed on
that date.

SECTION 1106. Fixed Rate Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Fixed Rate
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Partnership shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest. Upon surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Partnership at the Redemption Price, together with
accrued interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to 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 Fixed Rate Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal and any premium shall,
until paid, bear interest from the Redemption Date at the rate prescribed
therefor in such Security.

SECTION 1107. Fixed Rate Securities Redeemed in Part.

         Any Fixed Rate Security which is to be redeemed only in part shall be
surrendered at a Place of Payment therefor (with, if the Partnership or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Partnership and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Partnership
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Fixed Rate Security or Securities,
of any authorized denomination as requested by such


                                       73
<PAGE>   81

Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Fixed Rate Security so surrendered.

                                   ARTICLE XII

                                  NON-RECOURSE


SECTION 1201. Non-Recourse to the General Partner; No Personal Liability of
              Officers, Directors, Employees or Partners.

         Obligations of the Partnership or any Guarantor, as such, under this
Indenture, the Securities and any Guaranty are non-recourse to the General
Partner, and its respective Affiliates (other than the Partnership and the
Guarantors), and payable only out of cash flow and assets of the Partnership and
the Guarantors. The Trustee, and each Holder of a Security by its acceptance
thereof, will be deemed to have agreed in this Indenture that (1) neither the
General Partner nor its assets (nor any of its respective Affiliates other than
the Partnership or the Guarantors, nor their respective assets) shall be liable
for any of the obligations of the Partnership or the Guarantors under this
Indenture, such Securities or any Guaranty, and (2) no director, officer,
employee, stockholder or unitholder, as such, of the Partnership, the
Guarantors, the Trustee, the General Partner or any Affiliate of any of the
foregoing entities shall have any personal liability in respect of the
obligations of the Partnership or the Guarantors under this Indenture, such
Securities or any Guaranty by reason of his, her or its status. The agreements
set forth in this Section 1201 are part of the consideration for the issuance of
the Securities and any Guaranty.

                                  ARTICLE XIII

                       DEFEASANCE OF FIXED RATE SECURITIES

SECTION 1301. Applicability of Article.

         The provisions of this Article shall be applicable only to the Fixed
Rate Securities.

SECTION 1302. Legal Defeasance.

         In addition to discharge of the Indenture pursuant to Section 401, the
Partnership shall be deemed to have paid and discharged the entire indebtedness
on all Fixed Rate Securities on the 91st day after the date of the deposit
referred to in Clause (1) below, and the provisions of this Indenture with
respect to such Securities shall no longer be in effect (except as to (i) rights
of registration of transfer and exchange of such Securities and the
Partnership's right of optional redemption, (ii) substitution of mutilated,
destroyed, lost or stolen Securities, (iii) rights of Holders of such Securities
to receive payments of principal thereof and interest thereon, upon the original
stated due dates therefor or on the specified redemption dates therefor (but not
upon acceleration), (iv) the rights, obligations, duties and immunities of the
Trustee hereunder, and the Partnership's and Guarantors' obligations in
connection therewith (including, but not limited to, Section 607), (v) the
rights, if any, to convert or exchange such Securities, (vi) the rights of
Holders of such Securities as beneficiaries


                                       74
<PAGE>   82

hereof with respect to the property so deposited with the Trustee payable to all
or any of them, and (vii) the obligations of the Partnership under Section
1002), and the Trustee, at the expense of the Partnership, shall, upon a
Partnership Request, execute proper instruments acknowledging the same, if the
conditions set forth below are satisfied (hereinafter, "defeasance"):

                  (1) The Partnership has irrevocably deposited or caused to be
deposited with the Trustee as trust funds in trust, for the purposes of making
the following payments, specifically pledged as security for, and dedicated
solely to, the benefit of Holders of such Securities (A) cash in an amount, or
(B) U.S. Government Obligations, maturing as to principal and interest at such
times and in such amounts as will insure the availability of cash, or (C) a
combination thereof, certified to be sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay the principal and
interest and premium, if any, on all such Securities on each date that such
principal, interest or premium, if any, is due and payable or on any Redemption
Date established pursuant to Clause (3) below;

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

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

                  (4) No Event of Default or Default shall have occurred and be
continuing on the date of such deposit;

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

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

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


                                       75
<PAGE>   83

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

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

SECTION 1303. Covenant Defeasance.

         The Partnership and any other obligor, including the Guarantors, shall
be released on the 91st day after the date of the deposit referred to in Clause
(1) below from its obligations under Sections 704, 801, 1005, 1006 and 1007 with
respect to the Fixed Rate Securities on and after the date the conditions set
forth below are satisfied (hereinafter, "covenant defeasance"), and such
Securities shall thereafter be deemed to be not "Outstanding" for the purposes
of any request, demand, authorization, direction, notice, waiver, consent or
declaration or other action or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
Outstanding for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Securities, the Partnership and the
Guarantors may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such Section, whether directly or
indirectly by reason of any reference elsewhere herein to such Section or by
reason of any reference in such Section to any other provision herein or in any
other document and such omission to comply shall not constitute a Default or an
Event of Default under Section 501, but, except as specified above, the
remainder of this Indenture and the Securities of such Series shall be
unaffected thereby. The following shall be the conditions to application of this
Section 1303:

                  (1) The Partnership has irrevocably deposited or caused to be
deposited with the Trustee as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of Holders of the Securities of such Series (A) cash in an
amount, or (B) U.S. Government Obligations, maturing as to principal and
interest at such times and in such amounts as will insure the availability of
cash, or (C) a combination thereof, sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay the principal and
interest and premium, if any, on all Securities of such Series on each date that
such principal, interest or premium, if any, is due and payable or on any
Redemption Date established pursuant to Clause (2) below;

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


                                       76
<PAGE>   84

                  (3) No Event of Default or Default shall have occurred and be
continuing on the date of such deposit;

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

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

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

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

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

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

         Subject to the provisions of the last paragraph of Section 1003, all
moneys or U.S. Government Obligations deposited with the Trustee pursuant to
Section 1302 or 1303 (and all funds earned on such moneys or U.S. Government
Obligations) shall be held in trust and applied by it to the payment, either
directly or through any Paying Agent (including the Partnership acting as its
own Paying Agent), to Holders of such Securities for the payment or redemption
of which such moneys have been deposited with the Trustee, of all sums due and
to become due thereon for principal and interest; but such money need not be
segregated from other funds except to the extent required by law. Subject to
Sections 1302 and 1303, the Trustee shall promptly pay to the Partnership upon
Partnership Order any moneys held by it at any time, which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification delivered to the Trustee, are in excess of the amounts
required to effect the defeasance with respect to the Outstanding Securities in
question.

<PAGE>   85

SECTION 1305. Repayment to Partnership.

         The Trustee and any Paying Agent promptly shall pay or return to the
Partnership upon Partnership Request any money and U.S. Government Obligations
held by them at any time that are not required for the payment of the principal
of and any interest on such Securities for which money or U.S. Government
Obligations have been deposited pursuant to Section 1302 or 1303, which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification delivered to the Trustee, are in excess of
the amounts required to effect the defeasance with respect to the Outstanding
Securities in question.

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

SECTION 1306. Reinstatement.

         If the Trustee or the Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Article by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
obligations of the Partnership and any Guarantor under this Indenture, the
applicable Guaranty and the Securities of the applicable Series shall be revived
and reinstated as though no deposit had occurred pursuant to this Indenture
until such time as the Trustee or the Paying Agent is permitted to apply all
such money or U. S. Government Obligations in accordance with this Article;
provided, however, that if the Partnership or any Guarantor has made any payment
of principal of or interest on any Securities of such Series because of the
reinstatement of its obligations, the Partnership or such Guarantor shall be
subrogated to the rights of Holders of such Securities to receive such payment
from the money or U.S. Government Obligations held by the Trustee or the Paying
Agent.

                                   ARTICLE XIV

                             GUARANTY OF SECURITIES

SECTION 1401. Requirement for Guaranty.

                  (1) If any Subsidiary of the Partnership guarantees or becomes
a co-obligor in respect of any Funded Debt of the Partnership other than the
Securities at any time subsequent to the Closing Date (including, without
limitation, following any release of such Subsidiary pursuant to Section 1402
from any Guaranty previously provided by it under this Article XIV), then the
Partnership shall (A) cause the Securities to be equally and ratably guaranteed
by such Subsidiary, but only to the extent that the Securities are not already
guaranteed by such Subsidiary on reasonably comparable terms and (B) cause such
Subsidiary to execute and deliver a Guaranty in accordance with clause (2)
below.


                                       78
<PAGE>   86

                  (2) Any Person may become a Guarantor by executing and
delivering to the Trustee (A) a Guaranty in form and substance satisfactory to
the Trustee, which subjects such Person to the provisions (including the
representations and warranties) of this Indenture as a Guarantor and (B) an
Opinion of Counsel and Officers' Certificate to the effect that such Guaranty
has been duly authorized and executed by such Person and constitutes the legal,
valid, binding and enforceable obligation of such Person (subject to such
customary exceptions concerning creditors' rights and equitable principles as
may be acceptable to the Trustee in its discretion).

SECTION 1402. Release of Guaranty.

         Notwithstanding anything to the contrary in this Article XIV, in the
event that any Guarantor shall no longer be a guarantor of any Funded Debt of
the Partnership other than the Securities, and so long as no Default or Event of
Default shall have occurred or be continuing, such Guarantor, upon giving
written notice to the Trustee to the foregoing effect, shall be deemed to be
released from all of its obligations in respect of the Securities and this
Indenture without further act or deed and the Guaranty of such Guarantor shall
be of no further force or effect. Following the receipt by the Trustee of any
such notice, the Partnership shall cause this Indenture to be amended as
provided in Section 901; provided, however, that the failure to so amend this
Indenture shall not affect the validity of the termination of the Guaranty of
such Guarantor.

                                      * * *

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

                             "GUARANTY PROVISIONS"


SECTION 101. Unconditional Guaranties.

                  (1) For value received, the undersigned Guarantors, jointly
and severally, hereby fully, unconditionally and absolutely guarantee to Holders
and to the Trustee the due and punctual payment of the principal of, and
premium, if any, and interest on the Securities and all other amounts due and
payable under the Indenture and the Securities by the Partnership, when and as
such principal, premium, if any, and interest shall become due and payable,
whether at the stated maturity or by declaration of acceleration, call for
redemption or otherwise, according to the terms of the Securities and the
Indenture.

                  (2) Failing payment when due of any amount guaranteed pursuant
to the Guaranties, for whatever reason, each Guarantor will be obligated to pay
the same immediately. Each guaranty hereunder is intended to be a general,
unsecured, senior obligation of each undersigned Guarantor and will rank pari
passu in right of payment with all Debt of each such Guarantor that is not, by
its terms, expressly subordinated in right of payment to such guaranty of such
Guarantor. Each of the undersigned Guarantors hereby agrees that its obligations
hereunder shall be full, unconditional and absolute, irrespective of the
validity, regularity or enforceability of the Securities, this Guaranty or the
Indenture, the absence of any action to enforce the same, any waiver or consent
by any Holder of the Securities with respect to any provisions hereof or
thereof, any release of any other Guarantor, the recovery of any judgment
against the Partnership, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a Guarantor. Each of the undersigned Guarantors hereby agrees that in
the event of a default in payment of the principal of, or premium, if any, or
interest on the Securities, whether at the stated maturity or by declaration of
acceleration, call for redemption or otherwise, legal proceedings may be
instituted by the Trustee on behalf of Holders or, subject to Section 507 of the
Indenture, by Holders, on the terms and conditions set forth in the Indenture,
directly against each of the Guarantors to enforce this Guaranty without first
proceeding against the Partnership.

                  (3) The obligations of each undersigned Guarantor under this
Guaranty shall be as aforesaid full, unconditional and absolute and shall not be
impaired, modified, released or limited by any occurrence or condition
whatsoever, including, without limitation (A) any compromise, settlement,
release, waiver, renewal, extension, indulgence or modification of, or any
change in, any of the obligations and liabilities of the Partnership or any
Guarantor contained in the Securities, the Indenture or any other Guaranty, (B)
any impairment, modification, release or limitation of the liability of the
Partnership, any Guarantor or any of their estates in bankruptcy, or any remedy
for the enforcement thereof, resulting from the operation of any present or
future provision of any applicable Bankruptcy Law, as amended, or other statute
or from the decision of any court, (C) the assertion or exercise by the
Partnership, any Guarantor or the Trustee of any rights or remedies under the
Securities, the Indenture or any other Guaranty or their delay in or failure to
assert or exercise any such rights or remedies, (D) the assignment or the
purported assignment of any property as security for the Securities, including
all or any part of the rights of the Partnership or any Guarantor


                                      A-1
<PAGE>   89

under the Indenture or any other Guaranty, (E) the extension of the time for
payment by the Partnership or any Guarantor of any payments or other sums or any
part thereof owing or payable under any of the terms and provisions of the
Securities, the Indenture or any other Guaranty or of the time for performance
by the Partnership or any Guarantor of any other obligations under or arising
out of any such terms and provisions or the extension or the renewal of any
thereof, (F) the modification or amendment (whether material or otherwise) of
any duty, agreement or obligation of the Partnership or any Guarantor set forth
in the Indenture or any other Guaranty, (G) the voluntary or involuntary
liquidation, dissolution, sale or other disposition of all or substantially all
of the assets, marshaling of assets and liabilities, receivership, insolvency,
bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition or readjustment of, or other similar proceeding
affecting, the Partnership or any of the Guarantors or any of their respective
assets, or the disaffirmance of the Securities, this Guaranty or the Indenture
or any other Guaranty in any such proceeding, (H) the release or discharge of
the Partnership or any Guarantor from the performance or observance of any
agreement, covenant, term or condition contained in any of such instruments by
operation of law, (I) the unenforceability of the Securities, this Guaranty, any
other Guaranty or the Indenture or (J) any other circumstance which might
otherwise constitute a legal or equitable discharge of a surety or guarantor.

                  (4) Each of the undersigned Guarantors hereby (A) waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of the merger, insolvency or bankruptcy of the Partnership or a Guarantor,
and all demands whatsoever, (B) acknowledges that this Guaranty may be
transferred and that the benefit of its obligations hereunder shall extend to
each holder of any Securities without notice to them and (C) covenants that its
guaranty hereunder will not be discharged except by complete performance. Each
undersigned Guarantor further agrees that if at any time all or any part of any
payment hereunder theretofore applied by any Person is, or must be, rescinded or
returned for any reason whatsoever, including without limitation, the
insolvency, bankruptcy or reorganization of the Partnership or such Guarantor,
this Guaranty shall, to the extent that such payment is or must be rescinded or
returned, be deemed to have continued in existence notwithstanding such
application, and this Guaranty shall continue to be effective or be reinstated,
as the case may be, as though such application had not been made.

                  (5) Each undersigned Guarantor shall be subrogated to all
rights of Holders and the Trustee against the Partnership in respect of any
amounts paid by such Guarantor pursuant to the provisions of the Indenture or
this Guaranty, provided, however, that no Guarantor shall be entitled to enforce
or to receive any payments arising out of, or based upon, such right of
subrogation until all of the Securities and this Guaranty shall have been paid
in full or discharged.

                  (6) A director, officer, employee or stockholder, as such, of
any Guarantor shall not have any liability for any obligations of such Guarantor
under the Indenture or this Guaranty, or for any claim based on, in respect of
or by reason of such obligations or their creation.

SECTION 102. Limitation of Guarantor's Liability.

         Each undersigned Guarantor and by its acceptance hereof each Holder
hereby confirms that it is the intention of all such parties that the guarantee
by such Guarantor pursuant to this Guaranty not constitute a fraudulent transfer
or conveyance for purposes of any federal, state or foreign law. To effectuate
the foregoing intention, Holders and each Guarantor hereby irrevocably agree
that the obligations of each Guarantor under this Guaranty shall be limited to
the maximum amount as will, after giving effect to all other contingent and
fixed liabilities of such Guarantor and after giving effect to any collections
from or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under this Guaranty or pursuant to Section
103, result in the obligations of such Guarantor under this Guaranty not
constituting a fraudulent conveyance or fraudulent transfer under federal, state
or foreign law.

SECTION 103. Contribution.

         In order to provide for just and equitable contribution among all
Guarantors, the undersigned Guarantors agree, inter se, that in the event any
payment or distribution is made by any Guarantor (a "Funding Guarantor") under
its Guaranty, such Funding Guarantor shall be entitled to a contribution from
each other Guarantor in a pro rata amount based on the Adjusted Net Assets of
each Guarantor (including the Funding Guarantor) for all payments, damages and
expenses incurred by the Funding Guarantor in discharging the Partnership's
obligations with respect to the Securities or any other Guarantor's obligations
with respect to its Guaranty.

SECTION 104. Execution and Delivery of Guaranties.

         To further evidence the guaranty set forth in Section 101, each
undersigned Guarantor hereby agrees that a notation relating to such guaranty
(in substantially the form hereinbelow set forth) shall be endorsed on each
Security authenticated and delivered by the Trustee and executed by either
manual or facsimile signature of two officers of the Guarantor.

         Each of the undersigned Guarantors hereby agrees that its guaranty set
forth in Section 101 shall remain in full force and effect notwithstanding any
failure to endorse on each Security a notation relating to such guaranty.

         If an officer of a Guarantor whose signature is on this Guaranty or a
Security no longer holds that office at the time the Trustee authenticates such
Security or at any time thereafter, such Guarantor's Guaranty of such Security
shall be valid nevertheless.

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Guaranty on behalf of the Guarantor.


                                      A-3
<PAGE>   91

SECTION 105. Consent to Jurisdiction and Service of Process.

         Each undersigned Guarantor that is not organized under the laws of the
United States (including the States and the District of Columbia) (each a
"Non-U.S. Guarantor") hereby appoints the principal office of CT Corporation
System in The City of New York which, on the date hereof, is located at 1633
Broadway, New York, New York 10019, as the authorized agent thereof (the
"Authorized Agent") upon whom process may be served in any action, suit or
proceeding arising out of or based on the Indenture or this Guaranty or the
Securities which may be instituted in the Supreme Court of the State of New York
or the United States District Court for the Southern District of New York, in
either case in The Borough of Manhattan, The City of New York, by the Holder of
any Security, and each Non-United States Guarantor hereby waives any objection
which it may now or hereafter have to the laying of venue of any such proceeding
and expressly and irrevocably accepts and submits, for the benefit of Holders
from time to time of the Securities, to the nonexclusive jurisdiction of any
such court in respect of any such action, suit or proceeding, for itself and
with respect to its properties, revenues and assets. Such appointment shall be
irrevocable unless and until the appointment of a successor authorized agent for
such purpose, and such successor's acceptance of such appointment, shall have
occurred. Each Non-U.S. Guarantor agrees to take any and all actions, including
the filing of any and all documents and instruments, that may be necessary to
continue such appointment in full force and effect as aforesaid. Service of
process upon the Authorized Agent with respect to any such action shall be
deemed, in every respect, effective service of process upon any such Non-U.S.
Guarantor. Notwithstanding the foregoing, any action against any Non-U.S.
Guarantor arising out of or based on any Security may also be instituted by the
Holder of such Security in any court in the jurisdiction of organization of such
Non-U.S. Guarantor, and such Non-U.S. Guarantor expressly accepts the
jurisdiction of any such court in any such action. The Partnership shall require
the Authorized Agent to agree in writing to accept the foregoing appointment as
agent for service of process.

SECTION 106. Waiver of Immunity.

         To the extent that any Non-U.S. Guarantor or any of its properties,
assets or revenues may have or may hereafter become entitled to, or have
attributed to it, any right of immunity, on the grounds of sovereignty or
otherwise, from any legal action, suit or proceeding, from the giving of any
relief in any thereof, from set-off or counterclaim, from the jurisdiction of
any court, from service of process, from attachment upon or prior to judgment,
from attachment in aid of execution of judgment, or from execution of judgment,
or other legal process or proceeding for the giving of any relief or for the
enforcement of any judgment, in any jurisdiction in which proceedings may at any
time be commenced, with respect to its obligations, liabilities or any other
matter under or arising out of or in connection with the Indenture or this
Guaranty or the Securities, such Non-U.S. Guarantor, to the maximum extent
permitted by law, hereby irrevocably and unconditionally waives, and agrees not
to plead or claim, any such immunity and consents to such relief and
enforcement.


                                      A-4
<PAGE>   92

SECTION 107. Judgment Currency.

         Each Non-U.S. Guarantor agrees to indemnify the Trustee and each Holder
against any loss incurred by it as a result of any judgment or order being given
or made and expressed and paid in a currency (the "Judgment Currency") other
than Dollars and as a result of any variation as between (A) the rate of
exchange at which the Dollar amount is converted into the Judgment Currency for
the purpose of such judgment or order and (B) the spot rate of exchange in The
City of New York at which the Trustee or such Holder on the date of payment of
such judgment or order is able to purchase Dollars with the amount of the
Judgment Currency actually received by the Trustee or such Holder. The foregoing
indemnity shall constitute a separate and independent obligation of each
Non-U.S. Guarantor and shall continue in full force and effect notwithstanding
any such judgment or order as aforesaid. The term "spot rate of exchange" shall
include any premiums and costs of exchange payable in connection with the
purchase of, or conversion into, Dollars.

SECTION 108. Definitions.

         All capitalized terms used herein and not defined herein that are
defined in the Indenture are used herein as so defined.

         "Adjusted Net Assets" of a Guarantor at any date means the amount by
which the fair value of the property of such Guarantor at such date exceeds the
total amount of liabilities, including, without limitation, the probable amount
of contingent liabilities (after giving effect to all other fixed and contingent
liabilities incurred or assumed on such date) of such Guarantor at such date,
but excluding liabilities under the Guaranty of such Guarantor.

                          FORM OF GUARANTY ENDORSEMENT

         Each Guarantor (which term includes any successor Person under the
Guaranty, defined below), has fully, unconditionally and absolutely guaranteed,
to the extent set forth in the Indenture and in a certain Guaranty dated [ ]
(the "Guaranty"), and subject to the provisions in the Indenture and the
Guaranty, the due and punctual payment of the principal of, and premium, if any,
and interest on the Securities and all other amounts due and payable under the
Indenture and the Securities by the Partnership.

         The obligations of the Guarantors to Holders of Securities and to the
Trustee pursuant to the Guaranty and the Indenture are expressly set forth in
Article XIV of the Indenture and in the Guaranty, and reference is hereby made
to the Indenture and the Guaranty for the precise terms of such obligations.
