Section 1.02      Compliance Certificates and Opinions.

         Upon any application or request by the Partnership to the Trustee to
take any action under any provision of this Indenture, the Partnership shall
furnish to the Trustee an Officers' Certificate in form and substance reasonably
satisfactory to the Trustee stating that, in the opinion of the signers, all
conditions precedent and covenants, if any, provided for in this Indenture
relating to the proposed action have been complied with. Each such certificate
shall be given in the form of an Officers' Certificate and shall comply with the
requirements of the Trust Indenture Act and any other requirements set forth in
this Indenture.

         Every Officers' Certificate or Opinion of Counsel (except for
certificates provided for in Section 10.04) shall include:

         (1)      a statement that each individual signing such certificate or
opinion has read such covenant or condition and the definitions herein relating
thereto;

         (2)      a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in
such certificate or opinion are based;

         (3)      a statement that, in the opinion of each such individual, he
has made such examination or investigation as is necessary to enable him to
express an informed opinion as to whether or not such covenant or condition has
been complied with; and

         (4)      a statement as to whether, in the opinion of each such
individual, such condition or covenant has been complied with.

Section 1.03      Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
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.

         Any certificate of an officer of the Partnership or the General Partner
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 or
the General Partner stating that the information with respect to such factual
matters is in the possession of the Partnership or the General Partner, unless
such counsel knows that the certificate or opinion or representations with
respect to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture,

                                       11
<PAGE>

they may, but need not, be consolidated and form one instrument.

Section 1.04      Acts of Holders; Record Dates.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed (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 the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 315 of the
Trust Indenture Act) conclusive in favor of the Trustee and the Partnership, if
made in the manner provided in this Section.

         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, in the circumstances permitted by the Trust
Indenture Act, set any day as the record date for the purpose of determining the
Holders of Outstanding Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities of such series. With regard to any record date set pursuant to
this paragraph, the Holders of Outstanding Securities of the relevant series on
such record date (or their duly appointed agents), and only such Persons, shall
be entitled to give or take the relevant action,

                                       12
<PAGE>

whether or not such Holders remain Holders after such record date. With regard
to any action that may be given or taken hereunder only by Holders of a
requisite principal amount of Outstanding Securities of any series (or their
duly appointed agents) and for which a record date is set pursuant to this
paragraph, the Partnership may, at its option, set an expiration date after
which no such action purported to be given or taken by any Holder shall be
effective hereunder unless given or taken on or prior to such expiration date by
Holders of the requisite principal amount of Outstanding Securities of such
series on such record date (or their duly appointed agents). On or prior to any
expiration date set pursuant to this paragraph, the Partnership may, on one or
more occasions at its option, extend such date to any later date. Promptly after
setting such record date or expiration date, or extension thereof, the
Partnership shall notify in writing the Trustee and the Holder of Outstanding
Securities of such series of any record date or expiration date, or extension
thereof, so fixed. Nothing in this paragraph shall prevent any Holder (or any
duly appointed agent thereof) from giving or taking, after any such expiration
date, any action identical to, or, at any time, contrary to or different from,
the action or purported action to which such expiration date relates, in which
event the Partnership may set a record date in respect thereof pursuant to this
paragraph. Nothing in this paragraph shall be construed to render ineffective
any action taken at any time by the Holders (or their duly appointed agents) of
the requisite principal amount of Outstanding Securities of the relevant series
on the date such action is so taken. Notwithstanding the foregoing or the Trust
Indenture Act, the Partnership shall not set a record date for, and the
provisions of this paragraph shall not apply with respect to, any notice,
declaration or direction referred to in the next paragraph.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.02, if an Event of Default with respect to
Securities of such series has occurred and is continuing and the Trustee shall
not have given such a declaration to the Partnership, (iii) any request to
institute proceedings referred to in Section 5.07(2) or (iv) any direction
referred to in Section 5.12, in each case with respect to Securities of such
series. Promptly after any record date is set pursuant to this paragraph, the
Trustee shall notify in writing the Partnership and the Holders of Outstanding
Securities of such series of any such record date so fixed and the proposed
action. The Holders of Outstanding Securities of such series on such record date
(or their duly appointed agents), and only such Persons, shall be entitled to
join in such notice, declaration or direction, whether or not such Holders
remain Holders after such record date; provided that, unless such notice,
declaration or direction shall have become effective by virtue of Holders of the
requisite principal amount of Outstanding Securities of such series on such
record date (or their duly appointed agents) having joined therein on or prior
to the 90th day after such record date, such notice, declaration or direction
shall automatically and without any action by any Person be cancelled and of no
further effect. Nothing in this paragraph shall be construed to prevent a Holder
(or a duly appointed agent thereof) from giving, before or after the expiration
of such 90-day period, a notice, declaration or direction contrary to or
different from, or, after the expiration of such period, identical to, the
notice, declaration or direction to which such record date relates, in which
event a new record date in respect thereof shall be set pursuant to this
paragraph. Nothing in this paragraph shall be construed to render ineffective
any notice, declaration or direction of the type referred to in this paragraph
given at any time to the Trustee and the Partnership by Holders (or their duly
appointed agents) of the requisite principal amount of Outstanding Securities of
the relevant series on the date such notice, declaration or direction is so
given.

                                       13
<PAGE>

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

Section 1.05      Notices, Etc., to Trustee and Partnership.

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

         (1)      the Trustee by any Holder or by the Partnership shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing (which may be via facsimile) to or with the Trustee at its Corporate
Trust Office, Attention: Corporate Trust Department, or at any other address
previously furnished in writing by the Trustee, or

         (2)      the Partnership by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing (which may be via facsimile) and mailed, first-class
postage prepaid, to the Partnership addressed to it at 5 Radnor Corporate
Center, 100 Matsonford Road, Radnor, Pennsylvania, 19087, to the attention of
the Corporate Secretary, or at any other address previously furnished in writing
to the Trustee by the Partnership.

Section 1.06      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.

Section 1.07      Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or excluded, as the case may be. Wherever
this Indenture refers to a provision of the Trust Indenture Act, such provision
is incorporated by reference in and made a part of this Indenture. All terms
used in this Indenture that are defined by the Trust Indenture Act, defined by
the Trust Indenture Act referenced to another statute or defined by any rule of
the Commission and not otherwise defined herein shall have the meanings ascribed
to them thereby.

Section 1.08      Effect of Headings and Table of Contents.

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

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

Section 1.10      Separability Clause.

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

Section 1.11      Benefits of Indenture.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

Section 1.12      Governing Law.

         This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York.

Section 1.13      Legal Holidays.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of the Securities of any series which specifically
states that such provision shall apply in lieu of this Section)) payment of
interest or principal (and premium, if any) need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the

                                       15

Date, or at the Stated Maturity, provided that no interest shall accrue for the
intervening period.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act required or permitted under this Indenture shall be in the English

Section 1.15      Non-Recourse to the General Partner; No Personal Liability of
                  Officers, Directors, Employees or Partners.

         Obligations of the Partnership under this Indenture and the Securities
hereunder are non-recourse to the General Partner, and its respective Affiliates
(other than the Partnership), and payable only out of cash flow and assets of
the Partnership. The Trustee, and each Holder of a Security by its acceptance
thereof, will be deemed to have agreed in this Indenture that (1) neither the
General Partner nor its assets (nor any of its Affiliates, other than the
Partnership, or their respective assets) shall be liable for any of the
obligations of the Partnership under this Indenture or such Securities, and (2)
no director, officer, employee, stockholder or unitholder, as such, of the
Partnership, 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 under this Indenture or such Securities by reason
of his, her or its status.

         The Definitive Securities shall be printed, lithographed or engraved on
steel engraved borders or may be produced in any other manner, all as determined
by the officers executing

is payable on this Security is not a Business Day, then a payment of the
interest payable on such date will be made on the next succeeding day which is a

Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice of which shall be given to Holders of Securities of this
series not less than 10 days prior to such Special Record Date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange or automated quotation system on which the Securities of
this series may be listed or traded, and upon such notice as may be required by
such exchange or automated quotation system, all as more fully provided in such

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

written notice of a continuing Event of Default with respect to the Securities
of this series, the Holders of not less than a majority in principal amount of
the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee indemnity satisfactory to the Trustee

principal amount of Securities of this series at the time Outstanding a
direction inconsistent with such request, and shall have failed to institute any
such proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder of
this Security for the enforcement of any payment of principal hereof or [any
premium or] interest hereon on or after the respective due dates expressed
herein.

will be issued to the designated transferee or transferees.]

agreed in the Indenture that (1) neither the General Partner nor its assets (nor
any of its Affiliates, other than the Partnership, or their respective assets)
shall be liable for any of the obligations of the Partnership under the
Indenture or such Securities, including this Security, and (2) no director,
officer, employee, stockholder or unitholder, as such, of the Partnership, the
Trustee, the General Partner or any Affiliate of any of the foregoing entities
shall have any personal liability in respect of the obligations of the
Partnership under the Indenture or such Securities by reason of his, her or its
status.

                  OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN
                  THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY
                  MAY NOT BE TRANSFERRED TO, OR REGISTERED OR EXCHANGED FOR
                  SECURITIES REGISTERED IN THE NAME OF, ANY PERSON OTHER THAN
                  THE DEPOSITARY OR A NOMINEE THEREOF AND NO SUCH TRANSFER MAY
                  BE REGISTERED, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED
                  IN THE INDENTURE. EVERY SECURITY AUTHENTICATED AND DELIVERED
                  UPON REGISTRATION OF TRANSFER OF, OR IN EXCHANGE FOR OR IN
                  LIEU OF, THIS SECURITY SHALL BE A GLOBAL SECURITY SUBJECT TO
                  THE FOREGOING, EXCEPT IN SUCH LIMITED CIRCUMSTANCES.

         If Securities of a series are issuable in whole or in part in the form
of one or more Global Securities, as contemplated by Section 3.01, then,
notwithstanding Clause (9) of Section 3.01 and the provisions of Section 3.02,
any Global Security shall represent such of the Outstanding Securities of such
series as shall be specified therein and may provide that it shall represent the
aggregate amount of Outstanding Securities from time to time endorsed thereon
and that the aggregate amount of Outstanding Securities represented thereby may
from time to time be reduced or increased, as the case may be, to reflect
exchanges. Any endorsement of a Global Security to reflect the amount, or any
reduction or increase in the amount, of Outstanding Securities represented
thereby shall be made in such manner and upon instructions given by such Person
or Persons as shall be specified therein or in a Partnership Order. Subject to
the provisions of Sections 3.03, 3.04 and 3.05, the Trustee shall deliver and
redeliver any Global Security in the manner and upon written instructions given
by the Person or Persons specified therein or in the applicable Partnership
Order. Any instructions by the Partnership with respect to endorsement or
delivery or redelivery of a Global Security shall be in a Partnership Order
(which need not comply with Section 1.02 and need not be accompanied by an
Opinion of Counsel).

         The provisions of the last sentence of Section 3.03 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Partnership and the Partnership delivers to the Trustee the Global
Security together with a Partnership Order (which need not comply with Section
1.02 and need not be accompanied by an Opinion of Counsel) with regard to the
reduction or increase, as the case may be, in the principal amount of Securities
represented thereby, together with the written statement contemplated by the
last sentence of Section 3.03.

         All Securities of any one series shall be substantially identical

such indenture supplemental hereto.

         Any such Board Resolution or Officers' Certificate referred to above
with respect to Securities of any series filed with the Trustee on or before the

<PAGE>

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

         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 any Series executed by
the Partnership to the Trustee for authentication, together with a Partnership
Order for the authentication and delivery of such Securities, and the Trustee in
accordance with the Partnership Order shall authenticate and deliver such
Securities; provided, however, that in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of oral or electronic instructions from
the Partnership or its duly authorized agents, thereafter promptly confirmed in
writing) acceptable to the Trustee as may be specified by or pursuant to a
Partnership Order delivered to the Trustee prior to the time of the first
authentication of Securities of such series. If the form or terms of the
Securities of the series have been established in or pursuant to one or more
Board Resolutions as permitted by Sections 2.01 and 3.01, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, in
addition to any Officers' Certificate and Opinion of Counsel required to be
furnished to the Trustee pursuant to Section 1.02, and (subject to Section 6.01)
shall be fully protected in relying upon, an Opinion of

permitted by Section 2.01, that such form or forms have been established in
conformity with the provisions of this Indenture;

         (2)      if the terms of such Securities have been, or in the case of
Securities of a series offered in a Periodic Offering, will be, established by
or pursuant to a Board Resolution as permitted by Section 3.01, that such terms
have been, or in the case of Securities of a series offered in a Periodic
Offering, will be, established in conformity with the provisions of this
Indenture, subject, in the case of Securities of a series offered in a Periodic
Offering, to any conditions specified in such Opinion of Counsel (which
conditions are reasonably acceptable to the Trustee);

         (3)      that such Securities, when authenticated and delivered by the
Trustee and issued by the Partnership in the manner and subject to any
conditions specified in such Opinion of Counsel, which conditions are reasonably
acceptable to the Trustee, will constitute valid and legally binding obligations
of the Partnership enforceable in accordance with their terms, subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles and entitled to the benefits of this Indenture,
equally and ratably with all other Securities, if any, of such Series
Outstanding; and

         (4)      such other matters as the Trustee may reasonably request; and

if the authentication and delivery relates to a new series of Securities created
by an indenture supplemental hereto, also stating that all conditions precedent
to the execution of the supplemental indenture with respect to that series of
Securities have been complied with, the Partnership has the power to execute and
deliver any such supplemental indenture and has taken all necessary action for
those purposes and any such supplemental indenture has been executed and
delivered and constitutes the legal, valid and binding obligation of the
Partnership enforceable in accordance with its terms (subject, as to enforcement
of remedies, to applicable bankruptcy, reorganization, insolvency, fraudulent
conveyance, moratorium or other laws and legal principles affecting creditors'
rights generally from time to time in effect and to general equitable
principles, whether applied in an action at law or in equity).

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

         Notwithstanding the provisions of Section 3.01 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 3.01 or the Partnership Order and Opinion of
Counsel or Board Resolution or supplemental indenture otherwise required
pursuant to such preceding paragraph at or prior to the time of authentication
of each Security of such series if such documents are delivered at or prior to
the authentication upon original

                                       29
<PAGE>

issuance of the first Security of such series to be issued.

         With respect to Securities of a series not to be originally issued at
one time, the Trustee may rely upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 2.01 and 3.01 and this Section, as
applicable, in connection with the first authentication of Securities of such
series and any subsequent request by the Partnership to the Trustee to
authenticate Securities of such series upon original issuance shall constitute a
representation and warranty by the Partnership that as of the date of such
request, the statements made in the Officers' Certificate shall be true and
correct as if made on such date.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature of an authorized 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 3.09 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 3.04      Temporary Securities.

         Pending the preparation of Definitive Securities of any series, the
Partnership may execute, and upon receipt of the documents required by Section
3.03, 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 in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

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

Section 3.05      Registration, Registration of Transfer and Exchange.

         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 Trustee is hereby appointed 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 SunTrust
Bank c/o Computershare Trust Company of New York, 88 Pine Street, 19th Floor,
New York, New York 10005, 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 any
series at the office or agency of the Partnership maintained pursuant to Section
10.02 for such purpose, the Partnership shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor.

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

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

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

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Partnership may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.04 or 11.07 not involving any transfer.

         Neither the Trustee nor the Partnership shall be required (1) to issue,
register the transfer

                                       31
<PAGE>

of or exchange Securities of any series (or of any series and specified tenor,
as the case may be) during a period beginning at the opening of business 15 days
before the day of mailing of a notice of redemption of Securities of that series
selected for redemption under Section 11.03 and ending at the close of business
on the day of such mailing, or (2) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

         Notwithstanding any other provision in this Indenture, no Global
Security may be transferred to, or registered or exchanged for Securities
registered in the name of, any Person other than the Depositary for such Global
Security or any nominee thereof, and no such transfer may be registered, unless
(1) such Depositary (A) notifies the Partnership that it is unwilling or unable
to continue as Depositary for such Global Security or (B) has ceased to be a
clearing agency registered under the Exchange Act, (2) the Partnership executes
and delivers to the Trustee a Partnership order that such Global Security shall
be so transferred, registrable and exchangeable, and such transfers shall be
registrable, (3) there shall have occurred and be continuing an Event of Default
with respect to the Securities evidenced by such Global Security or (4) there
shall exist such other circumstances, if any, as have been specified for this
purpose as contemplated by Section 3.01. Notwithstanding any other provision in
this Indenture, a Global Security to which the restriction set forth in the
preceding sentence shall have ceased to apply may be transferred only to, and
may be registered and exchanged for Securities registered only in the name or
names of, such Person or Persons as the Depositary for such Global Security
shall have directed and no transfer thereof other than such a transfer may be
registered.

         Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security to which the
restriction set forth in the first sentence of the preceding paragraph shall
apply, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or 11.07 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security.

Section 3.06      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.

         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.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to

                                       32
<PAGE>

become due and payable, the Partnership in its discretion may, instead of
issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the
Partnership may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Every new Security of any series issued pursuant to this Section in exchange for
any mutilated Security or in lieu of any destroyed, lost or stolen Security
shall constitute an original additional contractual obligation of the
Partnership, 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 3.07      Payment of Interest; Interest Rights Preserved.

         Except as otherwise provided as contemplated by Section 3.01 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

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

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

                                       33
<PAGE>

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

         (2)      The Partnership may make payment of any Defaulted Interest on
the Securities of any series in any other lawful manner not inconsistent with
the requirements of any securities exchange or automated quotation system on
which such Securities may be listed or traded, and upon such notice as may be
required by such exchange, if, after written 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, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security, shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

Section 3.08      Persons Deemed Owners.

         Except as otherwise provided as contemplated by Section 3.01 with
respect to any series of Securities, prior to due presentment of a Security for
registration of transfer, the Partnership, the Trustee and any agent of the
Partnership or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of and any premium and (subject to Section 3.07) 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 3.09      Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled 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

                                       34
<PAGE>

any Securities previously authenticated hereunder which the Partnership has not
issued and sold, and all Securities so delivered shall be promptly cancelled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. All cancelled Securities held by the Trustee shall
be disposed of in accordance with its customary procedures, and the Trustee
shall thereafter deliver to the Partnership a certificate with respect to such
disposition.

Section 3.10      Computation of Interest.

         Except as otherwise specified as contemplated by Section 3.01 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

Section 3.11      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 in writing of any change in the "CUSIP" numbers.

                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

Section 4.01      Satisfaction and Discharge of Indenture.

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

         (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 3.06, 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 10.03)
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,

                                       35
<PAGE>

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

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

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

         (2)      the Partnership has paid or caused to be paid all other sums
payable hereunder by the Partnership with respect to such Securities including
the Trustee's reasonable fees and expenses incurred in connection with the
performance of its duties hereunder, including its reasonable attorney's fees;
and

         (3)      the Partnership has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this
Indenture with respect to such Securities have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to Securities of any series, (x) the obligations of the Partnership to
the Trustee under Section 6.07, the obligations of the Trustee to any
Authenticating Agent under Section 6.14 and the right of the Trustee to resign
under Section 6.10 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 4.02, 6.06,
7.01 and 10.02 and the last paragraph of Section 10.03 shall survive.

Section 4.02      Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 10.03, all
money deposited with the Trustee pursuant to Section 4.01 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.

any such decree or order for relief or any such other decree or order unstayed
and in effect for a period of 90 consecutive days; or

         (7)      any other Event of Default provided with respect to Securities

Section 5.02      Acceleration of Maturity; Rescission and Annulment.

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

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

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

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

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

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

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

         (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 5.13.

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

Section 5.03      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 the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal and any premium and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the reasonable costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem necessary 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 5.04      Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Partnership or any
other obligor upon the Securities, their property or their creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07.

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

Section 5.05      Trustee May Enforce Claims Without Possession of Securities.

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

Section 5.06      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
6.07;

         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 5.07      Limitation on Suits.

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

         (1)      such Holder has previously given written notice to the Trustee
of a continuing Event of Default with respect to the Securities of that series;

         (2)      the Holders of not less than a majority 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 security or indemnity satisfactory to it against the
costs, expenses and liabilities to be incurred in compliance with such request;

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

                                       40
<PAGE>

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

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

Section 5.08      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 Section
3.07) interest on such Security on the respective Stated Maturities expressed in
such Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

Section 5.09      Restoration of Rights and Remedies.

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

Section 5.10      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 3.06, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11      Delay or Omission Not Waiver.

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

                                       41

Section 5.12      Control by Holders.

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

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

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

         (3)      subject to the provisions of Section 6.01, the Trustee shall
have the right to decline to follow any such direction if the Trustee in good
faith shall determine that the proceeding so directed would involve the Trustee
in personal liability or would otherwise be contrary to applicable law.

Section 5.13      Waiver of Past Defaults.

         The Holders of not less than a majority in aggregate principal amount
of the Outstanding Securities of any series may on behalf of the Holders of all
the Securities of such series waive any past default hereunder with respect to
such series and its consequences, except

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

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

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

Section 5.14      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, that neither this Section nor the Trust Indenture Act
shall apply to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% of principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of principal of (or premium, if
any) or interest on any Security held by such Holder on or after the respective
Stated Maturities expressed by such Security (or, in the case of redemption or
repayment, on or after the Redemption Date); and provided, further, 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

                                       42
<PAGE>

assessment in any suit instituted by the Partnership.

Section 5.15      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

         The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed.

Section 6.01      Certain Duties and Responsibilities.

         (1)      If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture and use the same degree of care and skill in their exercise as a
prudent trustee would exercise or use under the circumstances in the conduct of
its own affairs.

         (2)      Except during the continuance of an Event of Default,

                  (a)      the Trustee need perform only those duties as are
specifically set forth in this Indenture and no others, and no covenants or
obligations shall be implied or read into this Indenture; and

                  (b)      in the absence of bad faith on its part, the Trustee
may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture. However, 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 substantially
conform to the requirements of this Indenture (but need not confirm or
investigate the genuineness of signatures thereto or the accuracy of
mathematical calculations or other facts stated therein).

         (3)      The Trustee may not be relieved from liability for its own
grossly negligent action, its own grossly negligent failure to act, or its own
willful misconduct, except that:

                  (a)      this Subsection does not limit the effect of
Subsection (2) of this Section;

                                       43
<PAGE>

                  (b)      the Trustee shall not be liable for any error of
judgment made in good faith by a responsible officer, unless it is proved that
the Trustee was grossly negligent in ascertaining the pertinent facts;

                  (c)      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 any series relating to the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred upon the Trustee, under this Indenture with respect to the
Securities of such series; and

                  (d)      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.

         (4)      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.

Section 6.02      Notice of Defaults.

         If a Default occurs and is continuing with respect to the Securities of
any series, the Trustee shall, within 90 days after it occurs, transmit, in the
manner and to the extent provided in Section 3.13(c) of the Trust Indenture Act,
notice of all uncured or unwaived Defaults known to it; provided, however, that,
except in the case of a Default in payment on the Securities of any series, the
Trustee 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 or breach of the
character specified in Section 5.01(3) with respect to the Securities of such
series, no such notice to Holders shall be given until at least 60 days after
the occurrence thereof.

Section 6.03      Certain Rights of Trustee.

         Subject to the provisions of Section 6.01:

         (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 (or in the case of a Periodic Offering, as agreed in
procedures set forth in a Partnership Order pursuant to Section 3.03) and any
resolution of the Board of Directors shall be sufficiently evidenced by a Board
Resolution;

                                       44
<PAGE>

         (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,
conclusively rely upon an Officers' Certificate;

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

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

         (6)      the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, notice, request, direction, consent, order, bond,
debenture, or other paper or 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 at the sole cost of the
Partnership and shall incur no liability or additional liability of any kind by
reason of such investigation.;

         (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 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;

         (9)      the Trustee shall not be deemed to have notice of any Event of
Default unless written notice of any event which is in fact such a default is
received by the Trustee at the Corporate Trust Office of the Trustee, and such
notice references the Securities and this Indenture; and

         (10)     the rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and each agent, custodian and other Person employed
to act hereunder.

Section 6.04      Individual Rights of Trustee.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any

                                       45
<PAGE>

other agent of the Partnership, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 6.09 and
6.14, 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 6.05      Money Held in Trust.

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

Section 6.06      Reports by Trustee to Holders.

         Within 60 days after each February 15 beginning with the February 15
following the date of this Indenture, the Trustee shall mail to each Holder a
brief report dated as of such February 15 that complies with Trust Indenture Act
Section 313(a) if such report is required by such Trust Indenture Act Section
313(a). The Trustee also shall comply with Trust Indenture Act Sections 313(b)
and 313(c).

         The Partnership shall promptly notify the Trustee in writing if the
Securities of any series become listed on any stock exchange or automatic
quotation system.

         A copy of each report at the time of its mailing to Holders shall be
mailed to the Partnership and filed with the Commission and each stock exchange,
if any, on which the Securities are listed.

Section 6.07      Compensation and Indemnity.

         The Partnership agrees:

         (1)      to pay to the Trustee from time to time reasonable and
customary 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), which compensation may be set
forth in a separate Letter Agreement between the Partnership and the Trustee;

         (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
gross negligence or bad faith; and

         (3)      to indemnify the Trustee for, and to hold it harmless against,
any loss, liability or expense incurred without negligence, willful misconduct
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 reasonable costs
and expenses of defending itself against any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder. The
Trustee shall notify the Partnership promptly in writing of any claim asserted
against the Trustee for which it

                                       46
<PAGE>

may seek indemnity. The Partnership shall defend the claim and the Trustee shall
provide reasonable cooperation at the Partnership's expense in the defense. The
Trustee may have separate counsel and the Partnership shall pay the reasonable
fees and expenses of such counsel. The Partnership need not pay for any
settlement made without its written consent which consent shall not be
unreasonably withheld or delayed. The Partnership need not reimburse any expense
or indemnify against any loss or liability to the extent incurred by the Trustee
as determined by a court of competent jurisdiction to have been caused by its
own gross negligence, bad faith or willful misconduct.

         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 5.01(5) or Section 5.01(6), 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 Partnership's obligations under this Section 6.07 and any lien
arising hereunder shall survive the resignation or removal of the Trustee, the
discharge of the Partnership's obligations pursuant to Article IV of this
Indenture and any rejection or termination of this Indenture under any
Bankruptcy Law.

Section 6.08      Disqualification; Conflicting Interests.

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

Section 6.09      Corporate Trustee Required; Eligibility.

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

Section 6.10      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 6.11.

                                       47
<PAGE>

         The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Partnership. If the
instrument of acceptance by a successor Trustee required by Section 6.11 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

         The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Partnership. If 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 6.08 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 6.09 and
shall fail to resign after written request therefor by the Partnership or by any
such Holder, or

         (3)      the Trustee shall become incapable of acting or shall be
adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property
shall be appointed or any public officer shall take charge or control of the
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case, (A) the Partnership, acting
pursuant to the authority of a Board Resolution, may remove the Trustee with
respect to all Securities, or (B) subject to Section 5.14, any Holder who has
been a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

         If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Partnership, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 6.11. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities of such
series delivered to the Partnership and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.11, become the
successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Partnership. If no
successor Trustee

                                       48
<PAGE>

with respect to the Securities of any series shall have been so appointed by the
Partnership or the Holders and accepted appointment in the manner required by
Section 6.11, 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 with respect to the Securities of such
series.

         The Partnership shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series to all
Holders of Securities of such series in the manner provided in Section 1.06.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

Section 6.11      Acceptance of Appointment by Successor.

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

         (2)      In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the
Partnership, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (A) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (B) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (C) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
as co-trustees of the same trust and that each such Trustee shall be trustee of
a trust or trusts hereunder separate and apart from any trust or trusts
hereunder administered by any other such Trustee; and upon the execution and
delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein and each
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, but, on request of the
Partnership or any successor Trustee, such

                                       49
<PAGE>

retiring Trustee shall, upon payment of its charges, duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

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

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

Section 6.12      Merger, Conversion, Consolidation or Succession to Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

Section 6.13      Preferential Collection of Claims Against Partnership.

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

Section 6.14      Appointment of Authenticating Agent.

         The Trustee (upon notice to the Partnership) may appoint an
Authenticating Agent or Agents with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of such series issued upon original issue (in accordance with
procedures acceptable to the Trustee) and upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 3.06, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Partnership and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as 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

                                       50
<PAGE>

Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

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

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

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:
This is one of the Securities of the series designated therein referred to in
the within-mentioned Indenture.

reasonably require, of the names and addresses of the Holders of Securities of
such series as of the preceding Regular Record Date, and

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

respect to such series of Securities.

Section 7.02      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 7.01 upon receipt of a new list so furnished.

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

         Every Holder of Securities, by receiving and holding the same, agrees

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

                                  ARTICLE VIII

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

Default shall have occurred or be continuing; and

         (4)      if a supplemental indenture is required in connection with
such transaction, the Partnership has delivered to the Trustee an Officers'
Certificate stating that such consolidation, merger, assignment, sale, transfer
or lease and such supplemental comply with this Article VIII and that all

Section 8.02      Successor Substituted.

         Upon any consolidation of the Partnership with, or merger of the
Partnership into, any other Person or any sale, transfer or lease of the

or into which the Partnership is merged or to which such sale, transfer or lease
is made shall succeed to, and be substituted for, and may exercise every right
and power of, the Partnership under this Indenture with the same effect as if
such successor Person had been named originally as the Partnership herein. When
a successor Person duly assumes all of the obligations of the Partnership
pursuant hereto and pursuant to the Securities, the predecessor shall be
relieved of the performance and observance of all obligations and covenants of
this Indenture and the Securities, including but not limited to the obligation
to make payment of the principal of and interest, if any, on all the Securities
then outstanding, and the Partnership may thereupon or any time thereafter be

         (3)      to add covenants of the Partnership for the benefit of the
Holders of all or any series of Securities (and if such covenants are to be for

not adversely affect the interests of the Holders;

         (4)      to add any additional Events of Default;

any series created prior to the execution of such supplemental indenture and
entitled to the benefit of such provision nor (ii) modify the rights of the
Holder of

                                       54

be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, pursuant to the requirements of Section
6.11;

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

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such

Indenture of the Holders of Securities of any other series.

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

Section 9.03      Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.01) shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

Section 9.04      Effect of Supplemental Indentures.

conform to the requirements of the Trust Indenture Act as then in effect.

Section 9.06      Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as

conform, in the opinion of the Trustee and the Partnership, to any such

                                    COVENANTS

Section 10.01     Payment of Principal, Premium and Interest.

         The Partnership covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities of that series and this Indenture. An installment of principal,
premium, if any, or interest on the Securities shall be considered paid on the
date it is due if the Trustee or Paying Agent (other than the Partnership or an
Affiliate of the Partnership) holds for the benefit of the Holders, on that
date, immediately available funds deposited and designated for and sufficient to
pay the installment.

Section 10.02     Maintenance of Office or Agency.

         The Partnership shall maintain in the Place of Payment for any series

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

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

contemplated by Section 3.01, the Partnership hereby initially designates as the

located at SunTrust Bank c/o Computershare Trust Company of New York, 88 Pine

Section 10.03     Money for Securities Payments to Be Held in Trust.

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

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

         The Partnership will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (1) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2)
during the continuance of any default by the Partnership (or any other obligor
upon the Securities of that series) in the making of any payment in respect of
the Securities of that series, upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

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

         Any money deposited with the Trustee or any Paying Agent in trust for
the payment of the principal of or any premium or interest on any Security of
any series and remaining unclaimed for two years after such principal, premium
or interest has become due and payable shall be paid to the state whose escheat
laws control and the Trustee or any 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 for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Partnership as trustee thereof, shall thereupon
cease.

Section 10.04     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
signer thereof the Partnership is in default in the performance

                                       58
<PAGE>

and observance of any of the terms, provisions and conditions of this Indenture
(without regard to any period of grace or requirement of notice provided
hereunder) and, if the Partnership shall be in default, specifying all such
defaults and the nature and status thereof of which they may have knowledge.

Section 10.05     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 material franchises; provided,
however, that the Partnership shall not be required to preserve any such right
or franchise if it shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Partnership.

Section 10.06     Limitations on Liens.

         The Partnership will not, nor will it permit any Restricted Subsidiary
to, create, assume, incur or suffer to exist any Lien upon any Principal
Property, or upon any Capital Interests of any Restricted 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 Restricted
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;

         (4)      any Lien upon any property or assets existing thereon at the
time of the acquisition thereof by the Partnership or any Restricted Subsidiary
(whether or not the obligations secured thereby are assumed by the Partnership
or any Restricted 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 Restricted 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 Restricted
Subsidiary;

                                       59
<PAGE>

         (6)      any Lien upon any property or assets of the Partnership or any
Restricted Subsidiary in existence on the Issue Date or provided for pursuant to
agreements existing on the Issue 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 in an
aggregate amount not in excess of $1,000,000 as to which the Partnership or the
applicable Restricted 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 (8), 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 Restricted 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 Restricted Subsidiary.

         Notwithstanding the foregoing provisions of this Section, the
Partnership may, and may permit any Restricted 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 10.07), does not exceed 10% of Consolidated Net Tangible Assets.

Section 10.07     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;

                                       60
<PAGE>

         (3)      the Attributable Indebtedness from that Sale-Leaseback
Transaction is an amount equal to or less than the amount the Partnership or
such Subsidiary would be allowed to incur as Debt secured by a Lien on the
Principal Property subject thereto 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 net sale proceeds from such Sale-Leaseback Transaction to (A)
the prepayment, repayment, redemption, reduction or retirement of any 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 10.06, do not exceed
10% of the Consolidated Net Tangible Assets.

Section 10.08     Waiver of Certain Covenants.

         The Partnership may omit in any particular instance to comply with any
term, provision or condition set forth in Section 10.05, 10.06 or 10.07 with
respect to the Securities of any series if before the time for such compliance
the Holders of at least a majority in aggregate principal amount of the
Outstanding Securities of all affected series (voting as one class) shall, by
Act of such Holders, either waive such compliance in such instance or generally
waive compliance with such term, provision or condition, but no such waiver
shall extend to or affect such term, provision or condition except to the extent
so expressly waived, and, until such waiver shall become effective, the
obligations of the Partnership and the duties of the Trustee in respect of any
such term, provision or condition shall remain in full force and effect.

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

                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

Section 11.01     Applicability of Article.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 3.01 for Securities of any
series) in accordance with this Article.

                                       61

Section 11.02     Election to Redeem; Notice to Trustee.

         The election of the Partnership to redeem any Securities shall be
evidenced by a Board Resolution. In case of any redemption at the election of
the Partnership of less than all the Securities of any series, the Partnership
shall, at least 60 days prior to the Redemption Date fixed by the Partnership
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee in writing of such Redemption Date, of the principal amount of
Securities of such series to be redeemed and, if applicable, of the tenor of the
Securities to be redeemed. In the case of any redemption of Securities (1) prior
to the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, or (2) pursuant to an election
of the Partnership which is subject to a condition specified in the terms of
such Securities, the Partnership shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restriction or condition.

Section 11.03     Selection by Trustee of Securities to be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem 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
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

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

Section 11.04     Notice of Redemption.

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

         All notices of redemption shall state:

         (1)      the Redemption Date,

         (2)      the Redemption Price,

                                       62
<PAGE>

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

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

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

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

         (7)      applicable CUSIP numbers.

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

Section 11.05     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 10.03) an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on, all the Securities which are to be redeemed
on that date.

Section 11.06     Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Partnership shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Partnership at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that, unless otherwise
specified as contemplated by Section 3.01, installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 3.07.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

<PAGE>

Section 11.07     Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Partnership or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Partnership and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Partnership shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities of the same series
and of like tenor, of any authorized denomination as requested by such Holder,
in aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Security so surrendered.

                                   ARTICLE XII

                                  SINKING FUNDS

Section 12.01     Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 3.01 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 12.02. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

Section 12.02     Satisfaction of Sinking Fund Payments with Securities.

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

Section 12.03     Redemption of Securities for Sinking Fund.

         Not less than 45 days prior to each sinking fund payment date for any
series of Securities (unless a shorter period shall be satisfactory to the
Trustee), the Partnership will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment

                                       64
<PAGE>

for that series pursuant to the terms of that series, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities of that
series pursuant to Section 12.02 and stating the basis for such credit and that
such Securities have not been previously so credited, and will also deliver to
the Trustee any Securities to be so delivered. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
11.03 and cause notice of the redemption thereof to be given in the name of and
at the expense of the Partnership in the manner provided in Section 11.04. Such
notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 11.06 and 11.07.

                                  ARTICLE XIII

                                   DEFEASANCE

Section 13.01     Applicability of Article.

         The provisions of this Article shall be applicable to each series of
Securities except as otherwise specified as contemplated by Section 3.01 for
Securities of such series.

Section 13.02     Legal Defeasance.

         In addition to discharge of the Indenture pursuant to Section 4.01, the
Partnership shall be deemed to have paid and discharged the entire indebtedness
on all the Securities of such a series on the 91st day after the date of the
deposit referred to in Clause (1) below, and the provisions of this Indenture
with respect to the Securities of such series shall no longer be in effect
(except as to (i) rights of registration of transfer and exchange of Securities
of such series and the Partnership's right of optional redemption, if any, (ii)
substitution of mutilated, destroyed, lost or stolen Securities, (iii) rights of
Holders of Securities to receive payments of principal thereof and interest
thereon, upon the original stated due dates therefor or on the specified
redemption dates therefor (but not upon acceleration), and remaining rights of
the holders to receive mandatory sinking fund payments, if any, (iv) the rights,
obligations, duties and immunities of the Trustee hereunder, and the
Partnership's obligations in connection therewith (including, but not limited
to, Section 6.07), (v) the rights, if any, to convert or exchange the Securities
of such series, (vi) the rights of the Holders of Securities of such series as
beneficiaries hereof with respect to the property so deposited with the Trustee
payable to all or any of them, and (vii) the obligations of the Partnership
under Section 10.02), and the Trustee, at the expense of the Partnership, shall,
upon a Partnership Request, execute proper instruments acknowledging the same,
if the conditions set forth below are satisfied (hereinafter, "defeasance"):

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

                                       65
<PAGE>

opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
(i) the principal and interest and premium, if any, on all Securities of such
series on each date that such principal, interest or premium, if any, is due and
payable or on any Redemption Date established pursuant to Clause (3) below, and
(ii) any mandatory sinking fund payments on the dates on which such payments are
due and payable in accordance with the terms of the Indenture and the Securities
of such series;

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

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

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

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

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

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

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

         For this purpose, such defeasance means that the Partnership and any
other obligor upon the Securities of such series shall be deemed to have paid
and discharged the entire debt represented by the Securities of such series,
which shall thereafter be deemed to be "Outstanding" only for the purposes of
Section 13.04 and the rights and obligations referred to in Clauses (i) through
(vii), inclusive, of the first paragraph of this Section, and to have satisfied
all its other obligations under the Securities of such series and this Indenture
insofar as the Securities of such series are concerned.

<PAGE>

Section 13.03     Covenant Defeasance.

         The Partnership and any other obligor, if any, shall be released on the
date of the deposit referred to in Clause (1) below from its obligations under
Sections 7.04, 8.01, 10.05, 10.06 and 10.07 with respect to the Securities of
any series on and after the date the conditions set forth below are satisfied
(hereinafter, "covenant defeasance"), and the Securities of such series shall
thereafter be deemed to be not "Outstanding" for the purposes of any request,
demand, authorization, direction, notice, waiver, consent or declaration or
other action or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed Outstanding for
all other purposes hereunder. For this purpose, such covenant defeasance means
that, with respect to the Securities of such series, the Partnership may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such Section, whether directly or indirectly by
reason of any reference elsewhere herein to such Section or by reason of any
reference in such Section to any other provision herein or in any other document
and such omission to comply shall not constitute a Default or an Event of
Default under Section 5.01, 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 13.03:

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

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

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

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

                                       67
<PAGE>

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

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

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

         (8)      The Partnership has delivered to the Trustee an Officers'
Certificate 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 13.04     Application by Trustee of Funds Deposited for Payment of
                  Securities.

         Subject to the provisions of the last paragraph of Section 10.03, all
moneys or U.S. Government Obligations deposited with the Trustee pursuant to
Section 13.02 or 13.03 (and all funds earned on such moneys or U.S. Government
Obligations) shall be held in trust and applied by it to the payment, either
directly or through any Paying Agent (including the Partnership acting as its
own Paying Agent), to the Holders of the particular Securities of such series
for the 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 13.02 and 13.03, 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.

Section 13.05     Repayment to Partnership.

         The Trustee and any Paying Agent promptly shall pay or return to the
Partnership upon Partnership Request any money and U.S. Government Obligations
held by them at any time that are not required for the payment of the principal
of and any interest on the Securities of any series for which money or U.S.
Government Obligations have been deposited pursuant to Section 13.02 or 13.03,
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 10.03 shall apply to
any money held by the Trustee or any Paying Agent under this Article that
remains unclaimed for two years after the Maturity of any series of Securities
for which money or U.S. Government Obligations have been deposited pursuant to
Section 13.02 or 13.03.

                                       68

Section 13.06     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 under this Indenture 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 has
made any payment of principal of or interest on any Securities of such series
because of the reinstatement of its obligations, the Partnership shall be
subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the Trustee or the
Paying Agent.

         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.
