thereof) and time of payment of interest, terms for redemption at the option of
the Operating Partnership or repayment at the option of the holder, terms for
sinking fund payments, covenants and any initial public offering price. In
addition, such specific terms may include limitations on direct or beneficial
ownership and restrictions on transfer of the Securities, in each case as may be
consistent with the Company's Articles of Incorporation, as then in effect, or
otherwise appropriate to preserve the status of the Company as a real estate
investment trust ("REIT") for federal income tax purposes. See "Restrictions on
Transfers of Capital Stock."
 
     The applicable Prospectus Supplement will also contain information, where
appropriate, about material United States federal income tax considerations

by such Prospectus Supplement.
 
     The Securities may be offered by the Company or the Operating Partnership
directly to one or more purchasers, through agents designated from time to time
by the Company or the Operating Partnership, or to or through underwriters or
dealers. If any agents or underwriters are involved in the sale of any of the
Securities, their names, and any applicable purchase price, fee, commission or
discount arrangement between or among them, will be set forth, or will be
calculable from the information set forth, in an accompanying Prospectus
Supplement. See "Plan of Distribution." No Securities may be sold without
delivery of a Prospectus Supplement describing the method and terms of the
offering of such Securities.

                   THE COMPANY AND THE OPERATING PARTNERSHIP
 
GENERAL
 
     Summit is one of the largest developers and operators of luxury garden
apartment communities in the southeastern United States. The Company is a
self-administered and self-managed real estate investment trust (a "REIT"). The
Company's Common Stock is listed on the New York Stock Exchange under the symbol
"SMT."
 
     The Company's business is conducted principally through the Operating
Partnership, of which the Company is the sole general partner and, as of March
31, 1997, the holder of approximately 84.5% of the outstanding units of
partnership interest of the Operating Partnership (the "Units"). Subject to
certain holding periods, each Unit, other than those held by the Company, may be
submitted by the holder thereof for redemption by the Operating Partnership. The
Company may, at its option, satisfy any redemption request by delivering cash or
one share (subject to certain adjustments) of Common Stock for each Unit
submitted for redemption. With each such exchange, the number of Units owned by
the Company and, therefore, the Company's percentage interest in the Operating
Partnership, will increase.
 
     The Company's third party management and certain construction and other
businesses are conducted through its subsidiaries, Summit Management Company, a
Maryland corporation (the "Management Company"), and Summit Apartment Builders,
Inc., a Florida corporation (the "Construction Company"). Unless the context
otherwise requires, the "Company" shall also hereinafter refer to the Operating
Partnership, the Management Company and the Construction Company.
 
     The Company was organized as a real estate investment trust under the laws
of the State of Maryland on December 1, 1993 and later changed to corporate form
on January 13, 1994. The Operating Partnership was organized as a limited
partnership under the laws of the State of Delaware on January 14, 1994. On
February 15, 1994, the Company completed its initial public offering of Common
Stock (the "Initial Offering"). The principal executive office of the Company
and the Operating Partnership is located at 212 South Tryon Street, Suite 500,
Charlotte, North Carolina 28281; telephone number (704) 334-9905.
 
                                USE OF PROCEEDS
 
     The Company is required by the terms of the partnership agreement of the
Operating Partnership, to invest the net proceeds of any sale of Common Stock or
Preferred Stock in the Operating Partnership in exchange for additional Units or
preferred Units, as the case may be. As will be more fully described in the
applicable Prospectus Supplement, the Company and the Operating Partnership
intend to use the net proceeds from the sale of Securities for general corporate
purposes, including repayment of indebtedness, investment in new communities and
new developments, and maintenance of currently owned communities.

                      RATIOS OF EARNINGS TO FIXED CHARGES
 
     The following table sets forth the consolidated ratios of earnings to fixed
charges for the Company, the Operating Partnership and the predecessor to the
Company and the Operating Partnership for the periods shown:
 
<TABLE>
<CAPTION>

   YEAR ENDED            YEAR ENDED            YEAR ENDED            YEAR ENDED            YEAR ENDED

</TABLE>
 
- ---------------
 
* Prior to the completion of the Initial Offering, the Company maintained a
  different capital structure. As a result, although the original properties
  have historically generated positive net cash flow, the financial statements
  of the Company show net losses for the fiscal years ended December 31, 1993
  and 1992. Consequently, the computation of the ratio of earnings to fixed
  charges for such periods indicates that earnings were inadequate to cover
  fixed charges by approximately $5.9 million and $9.9 million for the fiscal
  years ended December 31, 1993 and 1992, respectively.
 
     The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings consist of pre-tax income from
continuing operations plus fixed charges. Fixed charges consist of interest
expense (whether expensed or capitalized), rent expense, and the amortization of
debt issuance costs. To date, the Company has not issued any Preferred Stock;
therefore, the ratios of earnings to combined fixed charges and preferred stock
dividend requirements are the same as the ratios of earnings to fixed charges
presented above.
 
                         DESCRIPTION OF DEBT SECURITIES
 
GENERAL
 
     The Company conducts its business principally through the Operating
Partnership. Consequently, the Operating Partnership, and not the Company, will
issue the Debt Securities. The Debt Securities will be direct unsecured
obligations of the Operating Partnership and may be either senior Debt
Securities ("Senior Securities") or subordinated Debt Securities ("Subordinated
Securities"). The Debt Securities will be issued under one or more indentures,
each dated as of a date prior to the issuance of the Debt Securities to which it
relates. Senior Securities and Subordinated Securities may be issued pursuant to
separate indentures (respectively, a "Senior Indenture" and a "Subordinated
Indenture"), in each case between the Operating Partnership and a trustee (a
"Trustee"), which may be the same Trustee, and in the form that has been filed
as an exhibit to the Registration Statement of which this Prospectus is a part,
subject to such amendments or supplements as may be adopted from time to time.
The Senior Indenture and the Subordinated Indenture, as amended or supplemented
from time to time, are sometimes hereinafter referred to collectively as the
"Indentures." The Indentures will be subject to and governed by the Trust
Indenture Act of 1939, as amended (the "TIA"). The statements made under this
heading relating to the Debt Securities and the Indentures are summaries of the
anticipated material provisions thereof, do not purport to be complete and are
qualified in their entirety by reference to the Indentures and such Debt
Securities.
 
     Capitalized terms used herein and not defined shall have the meanings
assigned to them in the applicable Indenture.
 
TERMS
 
     The indebtedness represented by the Senior Securities will rank equally
with all other unsecured and unsubordinated indebtedness of the Operating
Partnership. The indebtedness represented by Subordinated Securities will be
subordinated in right of payment to the prior payment in full of the Senior Debt
of the Operating Partnership as described under " -- Subordination." The
particular terms of the Debt Securities offered by a Prospectus Supplement will
be described in the applicable Prospectus Supplement, along with any applicable
modifications of or additions to the general terms of the Debt Securities as
described herein and in the applicable Indenture and any applicable federal
income tax considerations. Accordingly, for a description of the terms of any
series of Debt Securities, reference must be made to both the Prospectus
Supplement relating thereto and the description of the Debt Securities set forth
in this Prospectus.
 
                                        4
<PAGE>   6
 
     Except as set forth in any Prospectus Supplement, the Debt Securities may
be issued without limit as to aggregate principal amount, in one or more series,
in each case as established from time to time by the Operating Partnership or as
set forth in the applicable Indenture or in one or more indentures supplemental
to such Indenture. All Debt Securities of 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 of the Debt Securities of such series, for issuance of
additional Debt Securities of such series.
 
     Each Indenture will provide that the Operating Partnership may, but need
not, designate more than one Trustee thereunder, each with respect to one or
more series of Debt Securities. Any Trustee under an Indenture may resign or be
removed with respect to one or more series of Debt Securities and a successor
Trustee may be appointed to act with respect to such series. In the event that
two or more persons are acting as Trustee with respect to different series of
Debt Securities, each such Trustee shall be a Trustee of a trust under the
applicable Indenture separate and apart from the trust administered by any other
Trustee, and, except as otherwise indicated herein, any action described herein
to be taken by each Trustee may be taken by each such Trustee with respect to,
and only with respect to, the one or more series of Debt Securities for which it
is Trustee under the applicable Indenture.
 
     The following summaries set forth certain general terms and provisions of
the Indentures and the Debt Securities. The Prospectus Supplement relating to
the series of Debt Securities being offered will contain further terms of such
Debt Securities, including the following specific terms:
 
      (1) The title of such Debt Securities and whether such Debt Securities are
          Senior Securities or Subordinated Securities;

      (3) The price (expressed as a percentage of the principal amount thereof)
          at which such Debt Securities will be issued and, if other than the
          principal amount thereof, the portion of the principal amount thereof
          payable upon declaration of acceleration of the maturity thereof;
 
      (4) The date or dates, or the method for determining such date or dates,
          on which the principal of such Debt Securities will be payable;
 
      (5) The rate or rates (which may be fixed or variable), or the method by
          which such rate or rates shall be determined, at which such Debt
          Securities will bear interest, if any;
 
      (6) The date or dates, or the method for determining such date or dates,
          from which any such interest will accrue, the dates on which any such
          interest will be payable, the record dates for such interest payment
          dates, or the method by which such dates shall be determined, the
          persons to whom such interest shall be payable, and the basis upon

          year of twelve 30-day months;
 
      (7) The place or places where the principal of (and premium, if any) and
          interest, if any, on such Debt Securities will be payable, where such
          Debt Securities may be surrendered for registration of transfer or
          exchange and where notices or demands to or upon the Operating
          Partnership in respect of such Debt Securities and the applicable
          Indenture may be served;
 
      (8) The period or periods, if any, within which, the price or prices at
          which and the other terms and conditions upon which such Debt
          Securities may, pursuant to any optional or mandatory redemption
          provisions, be redeemed, as a whole or in part, at the option of the
          Operating Partnership;
 
      (9) The obligation, if any, of the Operating Partnership to redeem, repay
          or purchase such Debt Securities pursuant to any sinking fund or
          analogous provision or at the option of a holder thereof, and the
          period or periods within which, the price or prices at which and the
          other terms and conditions upon which such Debt Securities will be

     (10) If other than U.S. dollars, the currency or currencies in which such
          Debt Securities are denominated and payable, which may be a foreign
          currency or units of two or more foreign currencies or a composite
          currency or currencies, and the terms and conditions relating thereto;
 
     (11) Whether the amount of payments of principal of (and premium, if any)
          or interest, if any, on such Debt Securities may be determined with
          reference to an index, formula or other method (which index, formula
          or method may, but need not be, based on a currency, currencies,
          currency unit or units, or composite currency or currencies) and the
          manner in which such amounts shall be determined;
 
     (12) Whether such Debt Securities will be issued in certificated or
          book-entry form and, if in book entry form, the identity of the

     (13) Whether such Debt Securities will be in registered or bearer form and,
          if in registered form, the denominations thereof if other than $1,000
          and any integral multiple thereof and, if in bearer form, the
          denominations thereof and terms and conditions relating thereto;
 
     (14) The applicability, if any, of the defeasance and covenant defeasance
          provisions described herein or set forth in the applicable Indenture,
          or any modification thereof;
 
     (15) Whether and under what circumstances the Operating Partnership will
          pay any additional amounts on such Debt Securities in respect of any
          tax, assessment or governmental charge and, if so, whether the
          Operating Partnership will have the option to redeem such Debt
          Securities in lieu of making such payment;
 
     (16) Any deletions from, modifications of or additions to the events of
          default or covenants of the Operating Partnership, to the extent
          different from those described herein or set forth in the applicable
          Indenture with respect to such Debt Securities, and any change in the
          right of any Trustee or any of the holders to declare the principal
          amount of any of such Debt Securities due and payable;
 
     (17) With respect to any Debt Securities that provide for optional
          redemption or prepayment upon the occurrence of certain events (such
          as a change of control of the Operating Partnership), (i) the possible
          effects of such provisions on the market price of the Operating
          Partnership's or the Company's securities or in deterring certain
          mergers, tender offers or other takeover attempts, and the intention
          of the Operating Partnership to comply with the requirements of Rule
          14e-1 under the Exchange Act and any other applicable securities laws
          in connection with such provisions; (ii) whether the occurrence of the
          specified events may give rise to cross-defaults on other indebtedness
          such that payment on such Debt Securities may be effectively
          subordinated; and (iii) the existence of any limitation on the
          Operating Partnership's financial or legal ability to repurchase such
          Debt Securities upon the occurrence of such an event (including, if
          true, the lack of assurance that such a repurchase can be effected)
          and the impact, if any, under the Indenture of such a failure,
          including whether and under what circumstances such a failure may
          constitute an event of default;
 
     (18) The name of the applicable trustee and the nature of any material
          relationship with the Operating Partnership or with any of its
          affiliates, and the percentage of Debt Securities of the class
          necessary to require the trustee to take action; and
 
     (19) Any other terms of such Debt Securities not inconsistent with the
          provisions of the applicable Indenture.
 
     If so provided in the applicable Prospectus Supplement, the Debt Securities
may be issued at a discount below their principal amount and provide for less
than the entire principal amount thereof to be payable upon declaration of
acceleration of the maturity thereof ("Original Issue Discount Securities"). In
such cases, any special U.S. federal income tax, accounting and other
considerations applicable to Original Issue Discount Securities will be
described in the applicable Prospectus Supplement.
 
                                        6

     Except as described under "Merger, Consolidation or Sale of Assets" or as
may be set forth in any Prospectus Supplement, the Debt Securities will not
contain any provisions that would limit the ability of the Operating Partnership
to incur indebtedness or that would afford holders of Debt Securities protection
in the event of (i) a highly leveraged or similar transaction involving the
Operating Partnership, the management of the Operating Partnership or the
Company, or any affiliate of any such party, (ii) a change of control, or (iii)
a reorganization, restructuring, merger or similar transaction involving the
Operating Partnership that may adversely affect the holders of the Debt
Securities. In addition, subject to the limitations set forth under "Merger,
Consolidation or Sale of Assets," the Operating Partnership may, in the future,
enter into certain transactions, such as the sale of all or substantially all of
its assets or the merger or consolidation of the Operating Partnership, that
would increase the amount of the Operating Partnership's indebtedness or
substantially reduce or eliminate the Operating Partnership's indebtedness or
substantially reduce or eliminate the Operating Partnership's assets, which may
have an adverse effect on the Operating Partnership's ability to service its
indebtedness, including the Debt Securities. Neither Maryland General
Corporation Law nor the governing instruments of the Company and the Operating
Partnership define the term "substantially all" in connection with the sale of
assets. Additionally, Maryland cases interpreting the words "substantially all"
all rely heavily upon the facts and circumstances of the particular case.
Consequently, to determine whether a sale of "substantially all" of the
Operating Partnership's assets has occurred, a holder of Debt Securities must
review the financial and other information disclosed by the Operating
Partnership to the public. Restrictions on ownership and transfers of the Common
Stock and Preferred Stock are designed to preserve the Company's status as a
REIT and, therefore, may act to prevent or hinder a change of control. See
"Restrictions on Transfers of Capital Stock." Reference is made to the
applicable Prospectus Supplement for information with respect to any deletions
from, modifications of, or additions to, the events of default or covenants that
are described below, including any addition of a covenant or other provision
providing event risk or similar protection.
 
DENOMINATION, INTEREST, REGISTRATION AND TRANSFER
 
     Unless otherwise described in the applicable Prospectus Supplement, the
Debt Securities of any series will be issuable in denominations of $1,000 and
integral multiples thereof.
 
     Subject to certain limitations imposed upon Debt Securities issued in
book-entry form, the Debt Securities of any series will be exchangeable for any
authorized denomination of other Debt Securities of the same series and of a
like aggregate principal amount and tenor upon surrender of such Debt Securities
at the corporate trust office of the applicable Trustee or at the office of any
transfer agent designated by the Operating Partnership for such purpose. In
addition, subject to certain limitations imposed upon Debt Securities issued in
book-entry form, the Debt Securities of any series may be surrendered for
registration of transfer or exchange thereof at the corporate trust office of
the applicable Trustee or at the office of any transfer agent designated by the
Operating Partnership for such purpose. Every Debt Security surrendered for
registration of transfer or exchange must be duly endorsed or accompanied by a
written instrument of transfer, and the person requesting such action must
provide evidence of title and identity satisfactory to the applicable Trustee or
transfer agent. No service charge will be made for any registration of transfer
or exchange of any Debt Securities, but the Trustee or the Operating Partnership
may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. If the applicable Prospectus Supplement
refers to any transfer agent (in addition to the applicable Trustee) initially
designated by the Operating Partnership with respect to any series of Debt
Securities, the Operating Partnership may at any time rescind the designation of
any such transfer agent or approve a change in the location through which any
such transfer agent acts, except that the Operating Partnership will be required
to maintain a transfer agent in each place of payment for such series. The
Operating Partnership may at any time designate additional transfer agents with
respect to any series of Debt Securities.
 
     Neither the Operating Partnership nor any Trustee shall be required (i) to
issue, register the transfer of or exchange Debt Securities of any series during
a period beginning at the opening of business 15 days before the day of mailing
of a notice of redemption of any Debt Securities that may be selected for
redemption and ending at the close of business on the day of such mailing; (ii)
to register the transfer of or exchange any Debt
 
                                        7
<PAGE>   9
 
Security, or portion thereof, so selected for redemption, in whole or in part,
except the unredeemed portion of any Debt Security being redeemed in part; or
(iii) to issue, register the transfer of or exchange any Debt Security that has
been surrendered for repayment at the option of the holder, except the portion,
if any, of such Debt Security not to be so repaid.
 
MERGER, CONSOLIDATION OR SALE OF ASSETS
 
     The Indentures will provide that the Operating Partnership may, without the
consent of the holders of any outstanding Debt Securities, consolidate with, or
sell, lease or convey all or substantially all of its assets to, or merge with
or into, any other entity provided that (i) either the Operating Partnership
shall be the continuing entity, or the successor entity (if other than the
Operating Partnership) formed by or resulting from any such consolidation or
merger or which shall have received the transfer of such assets, shall expressly
assume (A) the Operating Partnership's obligations to pay principal of (and
premium, if any) and interest on all of the Debt Securities and (B) the due and
punctual performance and observance of all of the covenants and conditions
contained in each Indenture; (ii) immediately after giving effect to such
transaction and treating any indebtedness that becomes an obligation of the
Operating Partnership or any subsidiary as a result thereof as having been
incurred by the Operating Partnership or such subsidiary at the time of such
transaction, no event of default under the Indentures, and no event which, after
notice or the lapse of time, or both, would become such an event of default,
shall have occurred and be continuing; and (iii) an officers' certificate and
legal opinion covering such conditions shall be delivered to each Trustee.
 
CERTAIN COVENANTS
 
     Existence.  Except as permitted under "--Merger, Consolidation or Sale of
Assets," the Indentures will require the Operating Partnership to do or cause to
be done all things necessary to preserve and keep in full force and effect its
existence, rights and franchises; provided, however, that the Operating
Partnership shall not be required to preserve any right or franchise if it
determines that the preservation thereof is no longer desirable in the conduct
of its business.
 
     Maintenance of Properties.  The Indentures will require the Operating
Partnership to cause all of its material properties used or useful in the
conduct of its business or the business of any subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Operating Partnership may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that the Operating Partnership and its subsidiaries shall not
be prevented from selling or otherwise disposing of their properties for value
in the ordinary course of business.
 
     Insurance.  The Indentures will require the Operating Partnership to cause
each of its and its subsidiaries' insurable properties to be insured against
loss or damage at least equal to their then full insurable value with insurers
of recognized responsibility and, if described in the applicable Prospectus
Supplement, having a specified rating from a recognized insurance rating
service.
 
     Payment of Taxes and Other Claims.  The Indentures will require the
Operating Partnership to pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (i) all taxes, assessments and
governmental charges levied or imposed upon it or any subsidiary or upon the
income, profits or property of the Operating Partnership or any subsidiary and
(ii) all lawful claims for labor, materials and supplies which, if unpaid, might
by law become a lien upon the property of the Operating Partnership or any
subsidiary; provided, however, that the Operating Partnership shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith.
 
     Additional Covenants.  Any additional covenants of the Operating
Partnership with respect to any series of Debt Securities will be set forth in
the Prospectus Supplement relating thereto.
 
                                        8
<PAGE>   10
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
     Unless otherwise provided in the applicable Prospectus Supplement, each
Indenture will provide that the following events are "Events of Default" with
respect to any series of Debt Securities issued thereunder: (i) default for 30
days in the payment of any installment of interest on any Debt Security of such
series; (ii) default in the payment of principal of (or premium, if any, on) any
Debt Security of such series at its maturity; (iii) default in making any
sinking fund payment as required for any Debt Security of such series; (iv)
default in the performance or breach of any other covenant or warranty of the
Operating Partnership contained in the Indenture (other than a covenant added to
the Indenture solely for the benefit of a series of Debt Securities issued
thereunder other than such series), continued for 60 days after written notice
as provided in the applicable Indenture; (v) a default under any bond,
debenture, note or other evidence of indebtedness for money borrowed (except
mortgage indebtedness) by the Operating Partnership or any of its subsidiaries
in an aggregate principal amount in excess of $25,000,000 or under any indenture
or instrument under which there may be issued or by which there may be secured
or evidenced any indebtedness for money borrowed (except mortgage indebtedness)
by the Operating Partnership or any of its subsidiaries in an aggregate
principal amount in excess of $25,000,000, whether such indebtedness exists on
the date of such Indenture or shall thereafter be created, which default shall
have resulted in such indebtedness becoming or being declared due and payable
prior to the date on which it would otherwise have become due and payable or
such obligations being accelerated, without such acceleration having been
rescinded or annulled; (vi) certain events of bankruptcy, insolvency or
reorganization, or court appointment of a receiver, liquidator or trustee of the
Operating Partnership or any Significant Subsidiary of the Operating
Partnership; and (vii) any other event of default provided with respect to a
particular series of Debt Securities. The term "Significant Subsidiary" has the
meaning ascribed to such term in Regulation S-X promulgated under the Securities
Act.
 
     If an event of default under any Indenture with respect to Debt Securities
of any series at the time outstanding occurs and is continuing, then in every
such case the applicable Trustee or the holders of not less than 25% in
principal amount of the Debt Securities of that series will have the right to
declare the principal amount (or, if the Debt Securities of that series are
Original Issue Discount Securities or indexed securities, such portion of the
principal amount as may be specified in the terms thereof) of all the Debt
Securities of that series to be due and payable immediately by written notice
thereof to the Operating Partnership (and to the applicable Trustee if given by
the holders). However, at any time after such a declaration of acceleration with
respect to Debt Securities of such series (or of all Debt Securities then
outstanding under any Indenture, as the case may be) has been made, but before a
judgment or decree for payment of the money due has been obtained by the
applicable Trustee, the holders of not less than a majority in principal amount
of outstanding Debt Securities of such series (or of all Debt Securities then
outstanding under the applicable Indenture, as the case may be) may rescind and
annul such declaration and its consequences if (i) the Operating Partnership
shall have deposited with the applicable Trustee all required payments of the
principal of (and premium, if any) and interest on the Debt Securities of such
series (or of all Debt Securities then outstanding under the applicable
Indenture, as the case may be), plus certain fees, expenses, disbursements and
advances of the applicable Trustee; and (ii) all events of default, other than
the non-payment of accelerated principal (or specified portion thereof), with
respect to Debt Securities of such series (or of all Debt Securities then
outstanding under the applicable Indenture, as the case may be) have been cured
or waived as provided in such Indenture. The Indentures will also provide that
the holders of not less than a majority in principal amount of the outstanding
Debt Securities of any series (or of all Debt Securities then outstanding under
the applicable Indenture, as the case may be) may waive any past default with
respect to such series and its consequences, except a default (i) in the payment
of the principal of (or premium, if any) or interest on any Debt Security of
such series; or (ii) in respect of a covenant or provision contained in the
applicable Indenture that cannot be modified or amended without the consent of
the holder of each outstanding Debt Security affected thereby.
 
     The Indentures will require each Trustee to give notice to the holders of
Debt Securities within 90 days of a default under the applicable Indenture
unless such default shall have been cured or waived; provided, however, that
such Trustee may withhold notice to the holders of any series of Debt Securities
of any default with respect to such series (except a default in the payment of
the principal of (or premium, if any) or interest
 
                                        9
<PAGE>   11
 
on any Debt Security of such series or in the payment of any sinking fund
installment in respect of any Debt Security of such series) if specified
responsible officers of such Trustee consider such withholding to be in the
interest of such holders.
 
     The Indentures will provide that no holders of Debt Securities of any
series may institute any proceedings, judicial or otherwise, with respect to
such Indenture or for any remedy thereunder, except in the case of failure of
the applicable Trustee, for 60 days, to act after it has received a written
request to institute proceedings in respect of an event of default from the
holders of not less than 25% in principal amount of the outstanding Debt
Securities of such series, as well as an offer of indemnity reasonably
satisfactory to it. This provision will not prevent, however, any holder of Debt
Securities from instituting suit for the enforcement of payment of the principal
of (and premium, if any) and interest on such Debt Securities at the respective
due dates thereof.
 
     The Indentures will provide that, subject to provisions in each Indenture
relating to its duties in case of default, a Trustee will be under no obligation
to exercise any of its rights or powers under an Indenture at the request or
direction of any holders of any series of Debt Securities then outstanding under
such Indenture, unless such holders shall have offered to the Trustee thereunder
reasonable security or indemnity. The holders of not less than a majority in
principal amount of the outstanding Debt Securities of any series (or of all
Debt Securities then outstanding under an Indenture, as the case may be) shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the applicable Trustee, or of exercising any trust
or power conferred upon such Trustee. However, a Trustee may refuse to follow
any direction which is in conflict with any law or the applicable Indenture,
which may involve such Trustee in personal liability or which may be unduly
prejudicial to the holders of Debt Securities of such series not joining
therein.
 
     Within 120 days after the close of each fiscal year, the Operating
Partnership will be required to deliver to each Trustee a certificate, signed by
one of several specified officers of Summit, as general partner of the Operating
Partnership, stating whether or not such officer has knowledge of any default
under the applicable Indenture and, if so, specifying each such default and the
nature and status thereof.
 
MODIFICATION OF THE INDENTURES
 
     Modifications and amendments of an Indenture will be permitted to be made
only with the consent of the holders of not less than a majority in principal
amount of all outstanding Debt Securities issued under such Indenture affected
by such modification or amendment; provided, however, that no such modification
or amendment may, without the consent of the holder of each such Debt Security
affected thereby, (i) change the stated maturity of the principal of, or any
installment of interest (or premium, if any) on, any such Debt Security; (ii)
reduce the principal amount of, or the rate or amount of interest on, or any
premium payable on redemption of, any such Debt Security, or reduce the amount
of principal of an Original Issue Discount Security that would be due and
payable upon declaration of acceleration of the maturity thereof or would be
provable in bankruptcy, or adversely affect any right of repayment of the holder
of any such Debt Security; (iii) change the place of payment, or the coin or
currency, for payment of principal of, premium, if any, or interest on any such
Debt Security; (iv) impair the right to institute suit for the enforcement of
any payment on or with respect to any such Debt Security; (v) reduce the
above-stated percentage of any outstanding Debt Securities necessary to modify
or amend the applicable Indenture with respect to such Debt Securities, to waive
compliance with certain provisions thereof or certain defaults and consequences
thereunder or to reduce the quorum or voting requirements set forth in the
applicable Indenture; or (vi) modify any of the foregoing provisions or any of
the provisions relating to the waiver of certain past defaults or certain
covenants, except to increase the required percentage to effect such action or
to provide that certain other provisions may not be modified or waived without
the consent of the holder of such Debt Security.
 
     The holders of a majority in aggregate principal amount of the outstanding
Debt Securities of each series may, on behalf of all holders of Debt Securities
of that series, waive, insofar as that series is concerned, compliance by the
Operating Partnership with certain restrictive covenants of the applicable
Indenture.
 
                                       10
<PAGE>   12
 
     Modifications and amendments of an Indenture will be permitted to be made
by the Operating Partnership and the respective Trustee thereunder without the
consent of any holder of Debt Securities for any of the following purposes: (i)
to evidence the succession of another person to the Operating Partnership as
obligor under such Indenture; (ii) to add to the covenants of the Operating
Partnership for the benefit of the holders of all or any series of Debt
Securities or to surrender any right or power conferred upon the Operating
Partnership in such Indenture; (iii) to add events of default for the benefit of
the holders of all or any series of Debt Securities; (iv) to add or change any
provisions of an Indenture to facilitate the issuance of, or to liberalize
certain terms of, Debt Securities in bearer form, or to permit or facilitate the
issuance of Debt Securities in uncertificated form, provided that such action
shall not adversely affect the interests of the holders of the Debt Securities
of any series in any material respect; (v) to change or eliminate any provisions
of an Indenture, provided that any such change or elimination shall become
effective only when there are no Debt Securities outstanding of any series
created prior thereto which are entitled to the benefit of such provision; (vi)
to secure the Debt Securities; (vii) to establish the form or terms of Debt
Securities of any series; (viii) to provide for the acceptance of appointment by
a successor Trustee or facilitate the administration of the trusts under an
Indenture by more than one Trustee; (ix) to cure any ambiguity, defect or
inconsistency in an Indenture, provided that such action shall not adversely
affect the interests of holders of Debt Securities of any series issued under
such Indenture; or (x) to supplement any of the provisions of an Indenture to
the extent necessary to permit or facilitate defeasance and discharge of any
series of such Debt Securities, provided that such action shall not adversely
affect the interests of the holders of the outstanding Debt Securities of any
series.
 
     The Indentures will provide that in determining whether the holders of the
requisite principal amount of outstanding Debt Securities of a series have given
any request, demand, authorization, direction, notice, consent or waiver
thereunder or whether a quorum is present at a meeting of holders of Debt
Securities, (i) the principal amount of an Original Issue Discount Security that
shall be deemed to be outstanding shall be the amount of the principal thereof
that would be due and payable as of the date of such determination upon
declaration of acceleration of the maturity thereof; (ii) the principal amount
of any Debt Security denominated in a foreign currency that shall be deemed
outstanding shall be the U.S. dollar equivalent, determined on the issue date
for such Debt Security, of the principal amount (or, in the case of an Original
Issue Discount Security, the U.S. dollar equivalent on the issue date of such
Debt Security of the amount determined as provided in (i) above); (iii) the
principal amount of an indexed security that shall be deemed outstanding shall
be the principal face amount of such indexed security at original issuance,
unless otherwise provided with respect to such indexed security pursuant to such
Indenture; and (iv) Debt Securities owned by the Operating Partnership or any
other obligor upon the Debt Securities or any affiliate of the Operating
Partnership or of such other obligor shall be disregarded.
 
     The Indentures will contain provisions for convening meetings of the
holders of Debt Securities of a series. A meeting will be permitted to be called
at any time by the applicable Trustee, and also, upon request, by the Operating
Partnership or the holders of at least 10% in principal amount of the
outstanding Debt Securities of such series, in any such case upon notice given
as provided in such Indenture. Except for any consent that must be given by the
holder of each Debt Security affected by certain modifications and amendments of
an Indenture, any resolution presented at a meeting or adjourned meeting duly
reconvened at which a quorum is present may be adopted by the affirmative vote
of the holders of a majority in principal amount of the outstanding Debt
Securities of that series; provided, however, that, except as referred to above,
any resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action that may be made, given or taken by the
holders of a specified percentage, which is less than a majority, in principal
amount of the outstanding Debt Securities of a series may be adopted at a
meeting or adjourned meeting duly reconvened at which a quorum is present by the
affirmative vote of the holders of such specified percentage in principal amount
of the outstanding Debt Securities of that series. Any resolution passed or
decision taken at any meeting of holders of Debt Securities of any series duly
held in accordance with an Indenture will be binding on all holders of Debt
Securities of that series. The quorum at any meeting called to adopt a
resolution, and at any reconvened meeting, will be persons holding or
representing a majority in principal amount of the outstanding Debt Securities
of a series; provided, however, that if any action is to be taken at such
meeting with respect to a consent or waiver which may be given by the holders of
not less than a
 
                                       11
<PAGE>   13
 
specified percentage in principal amount of the outstanding Debt Securities of a
series, the persons holding or representing such specified percentage in
principal amount of the outstanding Debt Securities of such series will
constitute a quorum.
 
     Notwithstanding the foregoing provisions, the Indentures will provide that
if any action is to be taken at a meeting of holders of Debt Securities of any
series with respect to any request, demand, authorization, direction, notice,
consent, waiver and other action that such Indenture expressly provides may be
made, given or taken by the holders of a specified percentage in principal
amount of all outstanding Debt Securities affected thereby, or of the holders of
such series and one or more additional series: (i) there shall be no minimum
quorum requirement for such meeting; and (ii) the principal amount of the
outstanding Debt Securities of such series that vote in favor of such request,
demand, authorization, direction, notice, consent, waiver or other action shall
be taken into account in determining whether such request, demand,
authorization, direction, notice, consent, waiver or other action has been made,
given or taken under such Indenture.
 
SUBORDINATION
 
     Unless otherwise provided in the applicable Prospectus Supplement,
Subordinated Securities will be subject to the following subordination
provisions.
 
     Upon any distribution to creditors of the Operating Partnership in a
liquidation, dissolution or reorganization, the payment of the principal of and
interest on any Subordinated Securities will be subordinated to the extent
provided in the applicable Indenture in right of payment to the prior payment in
full of all Senior Debt (as defined below), but the obligation of the Operating
Partnership to make payments of the principal of and interest on such
Subordinated Securities will not otherwise be affected. No payment of principal
or interest will be permitted to be made on Subordinated Securities at any time
if a default on Senior Debt exists that permits the holders of such Senior Debt
to accelerate its maturity and the default is the subject of judicial
proceedings or the Operating Partnership receives notice of the default. After
all Senior Debt is paid in full and until the Subordinated Securities are paid
in full, holders will be subrogated to the rights of holders of Senior Debt to
the extent that distributions otherwise payable to holders have been applied to
the payment of Senior Debt. The Subordinated Indenture will not restrict the
amount of Senior Debt or other indebtedness of the Operating Partnership and its
subsidiaries. As a result of these subordination provisions, in the event of a
distribution of assets upon insolvency, holders of Subordinated Indebtedness may
recover less, ratably, than general creditors of the Operating Partnership.
 
     Senior Debt will be defined in the applicable Indenture as the principal of
and interest on, or substantially similar payments to be made by the Operating
Partnership in respect of, the following, whether outstanding at the date of
execution of the applicable Indenture or thereafter incurred, created or
assumed: (i) indebtedness of the Operating Partnership for money borrowed or
represented by purchase-money obligations; (ii) indebtedness of the Operating
Partnership evidenced by notes, debentures, or bonds, or other securities issued
under the provisions of an indenture, fiscal agency agreement or other
agreement; (iii) obligations of the Operating Partnership as lessee under leases
of property either made as part of any sale and leaseback transaction to which
the Operating Partnership is a party or otherwise; (iv) indebtedness,
obligations and liabilities of others in respect of which the Operating
Partnership is liable contingently or otherwise to pay or advance money or
property or as guarantor, endorser or otherwise or which the Operating
Partnership has agreed to purchase or otherwise acquire; and (v) any binding
commitment of the Operating Partnership to fund any real estate investment or to
fund any investment in any entity making such real estate investment, in each
case other than (A) any such indebtedness, obligation or liability referred to
in clauses (i) through (iv) above as to which, in the instrument creating or
evidencing the same pursuant to which the same is outstanding, it is provided
that such indebtedness, obligation or liability is not superior in right of
payment to the Subordinated Securities or ranks pari passu with the Subordinated
Securities; (B) any such indebtedness, obligation or liability which is
subordinated to indebtedness of the Operating Partnership to substantially the
same extent as or to a greater extent than the Subordinated Securities are
subordinated; and (C) the Subordinated Securities. There will not be any
restrictions in any Indenture relating to Subordinated Securities upon the
creation of additional Senior Debt.

     If this Prospectus is being delivered in connection with a series of
Subordinated Securities, the accompanying Prospectus Supplement or the
information incorporated herein by reference will set forth the approximate
amount of Senior Debt outstanding as of the end of the Operating Partnership's
most recent fiscal quarter.
 
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Operating Partnership will be permitted, at its option, to discharge certain
obligations to holders of any series of Debt Securities issued under any
Indenture that have not already been delivered to the applicable Trustee for
cancellation and that either have become due and payable or will become due and
payable within one year (or scheduled for redemption within one year) by
irrevocably depositing with the applicable Trustee, in trust, funds in such
currency or currencies, currency unit or units or composite currency or
currencies in which such Debt Securities are payable in an amount sufficient to
pay the entire indebtedness on such Debt Securities in respect of principal (and
premium, if any) and interest to the date of such deposit (if such Debt
Securities have become due and payable) or to the stated maturity or redemption
date, as the case may be.
 
     The Indentures will provide that, unless otherwise indicated in the
applicable Prospectus Supplement, the Operating Partnership may elect either (i)
to defease and be discharged from any and all obligations with respect to such
Debt Securities (except for the obligation to pay additional amounts, if any,
upon the occurrence of certain events of tax, assessment or governmental charge
with respect to payments on such Debt Securities and the obligations to register
the transfer or exchange of such Debt Securities, to replace temporary or
mutilated, destroyed, lost or stolen Debt Securities, to maintain an office or
agency in respect of such Debt Securities, to hold moneys for payment in trust)
("defeasance"); or (ii) to be released from its obligations with respect to such
Debt Securities under the applicable Indenture (being the restrictions described
under " -- Certain Covenants") or, if provided in the applicable Prospectus
Supplement, its obligations with respect to any other covenant, and any omission
to comply with such obligations shall not constitute an event of default with
respect to such Debt Securities ("covenant defeasance"), in either case upon the
irrevocable deposit by the Operating Partnership with the applicable Trustee, in
trust, of an amount, in such currency or currencies, currency unit or units or
composite currency or currencies in which such Debt Securities are payable at
stated maturity, or Government Obligations (as defined below), or both,
applicable to such Debt Securities, which through the scheduled payment of
principal and interest in accordance with their terms will provide money in an
amount sufficient to pay the principal of (and premium, if any) and interest on
such Debt Securities, and any mandatory sinking fund or analogous payments
thereon, on the scheduled due dates therefor.
 
     Such a trust will only be permitted to be established if, among other
things, the Operating Partnership has delivered to the applicable Trustee an
opinion of counsel (as specified in the applicable Indenture) to the effect that
the holders of such Debt Securities will not recognize income, gain or loss for
U.S. federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to U.S. federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance or covenant defeasance had not occurred, and such opinion of counsel,
in the case of defeasance, will be required to refer to and be based upon a
ruling received from or published by the Internal Revenue Service (the
"Service") or a change in applicable United States federal income tax law
occurring after the date of the Indenture. In the event of such defeasance, the
holders of such Debt Securities would thereafter be able to look only to such
trust fund for payment of principal (and premium, if any) and interest.
 
     "Government Obligations" means securities that are (i) direct obligations
of the United States of America or the government which issued the foreign
currency in which the Debt Securities of a particular series are payable, for
the payment of which its full faith and credit is pledged; or (ii) obligations
of a person controlled or supervised by and acting as an agency or
instrumentality of the United States of America or such government which issued
the foreign currency in which the Debt Securities of such series are payable,
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America or such other government, which, in
either case, are not callable or redeemable at the option of the issuer thereof,
and shall also include a depository receipt issued by a bank or trust company as
custodian with
 
                                       13
<PAGE>   15
 
respect to any such Government Obligation or a specific payment of interest on
or principal of any such Government Obligation held by such custodian for the
account of the holder of a depository receipt; provided, however, that (except
as required by law) such custodian is not authorized to make any deduction from
the amount payable to the holder of such depository receipt from any amount
received by the custodian in respect of the Government Obligation or the
specific payment of interest on or principal of the Government Obligation
evidenced by such depository receipt.
 
     Unless otherwise provided in the applicable Prospectus Supplement, if after
the Operating Partnership has deposited funds and/or Government Obligations to
effect defeasance or covenant defeasance with respect to Debt Securities of any
series, (i) the holder of a Debt Security of such series is entitled to, and
does, elect pursuant to the applicable Indenture or the terms of such Debt
Security to receive payment in a currency, currency unit or composite currency
other than that in which such deposit has been made in respect of such Debt
Security; or (ii) a Conversion Event (as defined below) occurs in respect of the
currency, currency unit or composite currency in which such deposit has been
made, the indebtedness represented by such Debt Security will be deemed to have
been, and will be, fully discharged and satisfied through the payment of the
principal of (and premium, if any) and interest on such Debt Security as they
become due out of the proceeds yielded by converting the amount so deposited in
respect of such Debt Security into the currency, currency unit or composite
currency in which such Debt Security becomes payable as a result of such
election or such cessation of usage based on the applicable market exchange
rate. "Conversion Event" means the cessation of use of (i) a currency, currency
unit or composite currency both by the government of the country which issued
such currency and for the settlement of transactions by a central bank or other
public institutions of or within the international banking community; (ii) the
European Currency Unit ("ECU") both within the European Monetary System and for
the settlement of transactions by public institutions of or within the European
Communities; or (iii) any currency unit or composite currency other than the ECU
for the purposes for which it was established. Unless otherwise provided in the
applicable Prospectus Supplement, all payments of principal of (and premium, if
any) and interest on any Debt Security that is payable in a foreign currency
that ceases to be used by its government of issuance shall be made in U.S.
dollars.
 
     In the event the Company effects covenant defeasance with respect to any
Debt Securities and such Debt Securities are declared due and payable because of
the occurrence of any event of default other than the event of default described
in clause (iv) under "-- Events of Default, Notice and Waiver" with respect to
specified sections of an Indenture (which sections would no longer be applicable
to such Debt Securities) or described in clause (vii) under "Events of Default,
Notice and Waiver" with respect to any other covenant as to which there has been
covenant defeasance, the amount in such currency, currency unit or composite
currency in which such Debt Securities are payable, and Government Obligations
on deposit with the applicable Trustee, will be sufficient to pay amounts due on
such Debt Securities at the time of their stated maturity but may not be
sufficient to pay amounts due on such Debt Securities at the time of the
acceleration resulting from such event of default. However, the Operating
Partnership would remain liable to make payment of such amounts due at the time
of acceleration.
 
     The applicable Prospectus Supplement may further describe the provisions,
if any, permitting such defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
NO CONVERSION RIGHTS
 
     The Debt Securities will not be convertible into or exchangeable for any
capital stock of the Company or any equity interest in the Operating
Partnership.
 
PAYMENT
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and applicable premium, if any) and interest on any series of Debt
Securities will be payable at the corporate trust office of the Trustee, the
address of which will be stated in the applicable Prospectus Supplement;
provided, however, that, at the option of the Operating Partnership, payment of
interest may be made by check mailed to the
 
                                       14
<PAGE>   16
 
address of the person entitled thereto as it appears in the applicable register
for such Debt Securities or by wire transfer of funds to such person at an
account maintained within the United States.
 
     All moneys paid by the Operating Partnership to a paying agent or a Trustee
for the payment of the principal of or any premium or interest on any Debt
Security which remain unclaimed at the end of two years after such principal,
premium or interest has become due and payable will be repaid to the Operating
Partnership, and the holder of such Debt Security thereafter may look only to
the Operating Partnership for payment thereof.
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities (the "Global Securities") that will be
deposited with, or on behalf of, a depositary identified in the applicable
Prospectus Supplement relating to such series. Global Securities may be issued
in either registered or bearer form and in either temporary or permanent form.
The specific terms of the depositary arrangement with respect to a series of
Debt Securities will be described in the applicable Prospectus Supplement
relating to such series.
 
                         DESCRIPTION OF PREFERRED STOCK
 
     The description of the Company's Preferred Stock set forth below does not
purport to be complete and is qualified in its entirety by reference to the
Company's Articles of Incorporation (the "Articles of Incorporation") and Bylaws
(the "Bylaws"), as in effect from time to time.
 
GENERAL
 
     Under the Articles of Incorporation, the Company has authority to issue 25
million shares of Preferred Stock, par value $.01 per share, none of which was
outstanding as of the date of this Prospectus. Under Maryland law, stockholders
generally are not responsible for the corporation's debts or obligations. Shares
of Preferred Stock may be issued from time to time, in one or more series, as
authorized by the Board of Directors of the Company. Prior to issuance of shares
of each series, the Board of Directors is required by the Maryland General
Corporation Law ("MGCL") and the Company's Articles of Incorporation to fix for
each series, subject to the provisions of the Company's Articles of
Incorporation regarding excess stock, $.01 par value per share ("Excess Stock"),
the terms, preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends or other distributions, qualifications and terms or
conditions of redemption, as are permitted by Maryland law. The Preferred Stock
will, when issued, be fully paid and nonassessable and will have no preemptive
rights. The Board of Directors could authorize the issuance of shares of
Preferred Stock with terms and conditions that could have the effect of
discouraging a takeover or other transaction that holders of Common Stock might
believe to be in their best interests or in which holders of some, or a
majority, of the shares of Common Stock might receive a premium for their shares
over the then market price of such shares of Common Stock.
 
TERMS
 
     The following description of the Preferred Stock sets forth certain general
terms and provisions of the Preferred Stock to which any Prospectus Supplement
may relate. The statements below describing the Preferred Stock are in all
respects subject to and qualified in their entirety by reference to the
applicable provisions of the Company's Articles of Incorporation and Bylaws and
any applicable amendment to the Articles of Incorporation designating terms of a
series of Preferred Stock (a "Designating Amendment").

Stock offered thereby for specific terms, including:
 
      (1) The title and stated value of such Preferred Stock;
 
      (2) The number of shares of such Preferred Stock offered, the liquidation

                                       15
<PAGE>   17
 
      (3) The dividend rate(s), period(s) and/or payment date(s) or method(s) of
          calculation thereof applicable to such Preferred Stock;
 
      (4) The date from which dividends on such Preferred Stock shall
          accumulate, if applicable;
 
      (5) The procedures for any auction and remarketing, if any, for such
          Preferred Stock;
 
      (6) The provision for a sinking fund, if any, for such Preferred Stock;
 
      (7) The provision for redemption, if applicable, of such Preferred Stock;
 
      (8) Any listing of such Preferred Stock on any securities exchange;
 
      (9) The terms and conditions, if applicable, upon which such Preferred
          Stock will be convertible into Common Stock, including the conversion
          price or rate (or manner of calculation thereof);
 
     (10) Any other specific terms, preferences, rights, limitations or
          restrictions of such Preferred Stock;
 
     (11) A discussion of federal income tax considerations applicable to such
          Preferred Stock;
 
     (12) The relative ranking and preference of such Preferred Stock as to
          dividend rights and rights upon liquidation, dissolution or winding up
          of the affairs of the Company;
 
     (13) Any limitations on issuance of any series of Preferred Stock ranking
          senior to or on a parity with such series of Preferred Stock as to
          dividend rights and rights upon liquidation, dissolution or winding up
          of the affairs of the Company; and
 
     (14) Any limitations on direct or beneficial ownership and restrictions on
          transfer, in each case as may be appropriate to preserve the status of
          the Company as a REIT.
 
RANK
 
     Unless otherwise specified in the Prospectus Supplement, the Preferred
Stock will, with respect to dividend rights and rights upon liquidation,
dissolution or winding up of the Company, rank (i) senior to all classes or
series of Common Stock of the Company, and to all equity securities ranking
junior to such Preferred Stock with respect to dividend rights or rights upon
liquidation, dissolution or winding up of the Company; (ii) on a parity with all
equity securities issued by the Company, the terms of which specifically provide
that such equity securities rank on a parity with the Preferred Stock with
respect to dividend rights or rights upon liquidation, dissolution or winding up
of the Company; and (iii) junior to all equity securities issued by the Company,
the terms of which specifically provide that such equity securities rank senior
to the Preferred Stock with respect to dividend rights or rights upon
liquidation, dissolution or winding up of the Company. The term "equity
securities" does not include convertible debt securities.
 
DIVIDENDS
 
     Holders of the Preferred Stock of each series will be entitled to receive,
when, as and if declared by the Board of Directors of the Company, out of assets
of the Company legally available for payment, cash dividends at such rates and
on such dates as will be set forth in the applicable Prospectus Supplement. Each
such dividend shall be payable to holders of record as they appear on the share
transfer books of the Company on such record dates as shall be fixed by the
Board of Directors of the Company.
 
     Dividends on any series of the Preferred Stock may be cumulative or
non-cumulative, as provided in the applicable Prospectus Supplement. Dividends,
if cumulative, will be cumulative from and after the date set forth in the
applicable Prospectus Supplement. If the Board of Directors of the Company fails
to declare a dividend payable on a dividend payment date on any series of the
Preferred Stock for which dividends are non-cumulative, then the holders of such
series of the Preferred Stock will have no right to receive a dividend in
respect of the dividend period ending on such dividend payment date, and the
Company will have no obligation to pay the dividend accrued for such period,
whether or not dividends on such series are declared payable on any future
dividend payment date.
 
                                       16
<PAGE>   18
 
     If Preferred Stock of any series is outstanding, no dividends will be
declared or paid or set apart for payment on any capital stock of the Company of
any other series ranking, as to dividends, on a parity with or junior to the
Preferred Stock of such series for any period unless (i) if such series of
Preferred Stock has a cumulative dividend, full cumulative dividends have been
or contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof is set apart for such payment on the Preferred Stock of such
series for all past dividend periods and the then current dividend period; or
(ii) if such series of Preferred Stock does not have a cumulative dividend, full
dividends for the then current dividend period have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
is set apart for such payment on the Preferred Stock of such series. When
dividends are not paid in full (or a sum sufficient for such full payment is not
so set apart) upon Preferred Stock of any series and the shares of any other
series of Preferred Stock ranking on a parity as to dividends with the Preferred
Stock of such series, all dividends declared upon Preferred Stock of such series
and any other series of Preferred Stock ranking on a parity as to dividends with
such Preferred Stock shall be declared pro rata so that the amount of dividends
declared per share of Preferred Stock of such series and such other series of
Preferred Stock shall in all cases bear to each other the same ratio that
accrued dividends per share on the Preferred Stock of such series (which shall
not include any accumulation in respect of unpaid dividends for prior dividend
periods if such Preferred Stock does not have a cumulative dividend) and such
other series of Preferred Stock bear to each other. No interest, or sum of money
in lieu of interest, shall be payable in respect of any dividend payment or
payments on Preferred Stock of such series which may be in arrears.
 
     Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Stock has a cumulative dividend, full cumulative
dividends on the Preferred Stock of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
is set apart for payment for all past dividend periods and the then current
dividend period; and (ii) if such series of Preferred Stock does not have a
cumulative dividend, full dividends on the Preferred Stock of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof is set apart for payment for the then current dividend
period, no dividends (other than in shares of Common Stock or other shares of
capital stock ranking junior to the Preferred Stock of such series as to
dividends and upon liquidation) shall be declared or paid or set aside for
payment nor shall any other distribution be declared or made upon the Common
Stock, or any other capital stock of the Company ranking junior to or on a
parity with the Preferred Stock of such series as to dividends or upon
liquidation, nor shall any shares of Common Stock, or any other shares of
capital stock of the Company ranking junior to or on a parity with the Preferred
Stock of such series as to dividends or upon liquidation be redeemed, purchased
or otherwise acquired for any consideration (or any moneys be paid to or made
available for a sinking fund for the redemption of any such shares) by the
Company (except by conversion into or exchange for other capital stock of the
Company ranking junior to the Preferred Stock of such series as to dividends and
upon liquidation).
 
     Any dividend payment made on shares of a series of Preferred Stock shall
first be credited against the earliest accrued but unpaid dividend due with
respect to shares of such series which remains payable.
 
REDEMPTION
 
     If so provided in the applicable Prospectus Supplement, the Preferred Stock
will be subject to mandatory redemption or redemption at the option of the
Company, as a whole or in part, in each case upon the terms, at the times and at
the redemption prices set forth in such Prospectus Supplement.
 
     The Prospectus Supplement relating to a series of Preferred Stock that is
subject to mandatory redemption will specify the number of shares of such
Preferred Stock that shall be redeemed by the Company in each year commencing
after a date to be specified, at a redemption price per share to be specified,
together with an amount equal to all accrued and unpaid dividends thereon (which
shall not, if such Preferred Stock does not have a cumulative dividend, include
any accumulation in respect of unpaid dividends for prior dividend periods) to
the date of redemption. The redemption price may be payable in cash or other
property, as specified in the applicable Prospectus Supplement. If the
redemption price for Preferred Stock of any series is payable only from the net
proceeds of the issuance of shares of capital stock of the Company, the terms of
such Preferred Stock may provide that, if no such shares of capital stock shall
have been issued or to the
 
                                       17
<PAGE>   19
 
extent the net proceeds from any issuance are insufficient to pay in full the
aggregate redemption price then due, such Preferred Stock shall automatically
and mandatorily be converted into the applicable shares of capital stock of the
Company pursuant to conversion provisions specified in the applicable Prospectus
Supplement.
 
     Notwithstanding the foregoing, unless (i) if a series of Preferred Stock
has a cumulative dividend, full cumulative dividends on all shares of such
series of Preferred Stock shall have been or contemporaneously are declared and
paid or declared and a sum sufficient for the payment thereof set apart for
payment for all past dividend periods and the then current dividend period; and
(ii) if a series of Preferred Stock does not have a cumulative dividend, full
dividends on all shares of the Preferred Stock of such series have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for the then current dividend period, no
shares of such series of Preferred Stock shall be redeemed unless all
outstanding shares of Preferred Stock of such series are simultaneously
redeemed; provided, however, that the foregoing shall not prevent the purchase
or acquisition of Preferred Stock of such series to preserve the REIT status of
the Company or pursuant to a purchase or exchange offer made on the same terms
to holders of all outstanding shares of Preferred Stock of such series. In
addition, unless (i) if such series of Preferred Stock has a cumulative
dividend, full cumulative dividends on all outstanding shares of such series of
Preferred Stock have been or contemporaneously are declared and paid or declared
and a sum sufficient for the payment thereof set apart for payment for all past
dividend periods and the then current dividend period; and (ii) if such series
of Preferred Stock does not have a cumulative dividend, full dividends on the
Preferred Stock of such series have been or contemporaneously are declared and
paid or declared and a sum sufficient for the payment thereof set apart for
payment for the then current dividend period, the Company shall not purchase or
otherwise acquire directly or indirectly any shares of Preferred Stock of such
series (except by conversion into or exchange for capital shares of the Company
ranking junior to the Preferred Stock of such series as to dividends and upon
liquidation); provided, however, that the foregoing shall not prevent the
purchase or acquisition of shares of Preferred Stock of such series to preserve
the REIT status of the Company or pursuant to a purchase or exchange offer made
on the same terms to holders of all outstanding shares of Preferred Stock of
such series.
 
     If fewer than all of the outstanding shares of Preferred Stock of any
series are to be redeemed, the number of shares to be redeemed will be
determined by the Company and such shares may be redeemed pro rata from the
holders of record of such shares in proportion to the number of such shares held
or for which redemption is requested by such holder (with adjustments to avoid
redemption of fractional shares) or by any other equitable manner determined by
the Company.
 
     Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of record of Preferred Stock of
any series to be redeemed at the address shown on the stock transfer books of
the Company. Each notice shall state: (i) the redemption date; (ii) the number
of shares and series of the Preferred Stock to be redeemed; (iii) the redemption
price; (iv) the place or places where certificates for such Preferred Stock are
to be surrendered for payment of the redemption price; (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption date; and (vi) the
date upon which the holder's conversion rights, if any, as to such shares shall
terminate. If fewer than all the shares of Preferred Stock of any series are to
be redeemed, the notice mailed to each such holder thereof shall also specify
the number of shares of Preferred Stock to be redeemed from each such holder. If
notice of redemption of any Preferred Stock has been given and if the funds
necessary for such redemption have been set aside by the Company in trust for
the benefit of the holders of any Preferred Stock so called for redemption, then
from and after the redemption date dividends will cease to accrue on such
Preferred Stock, and all rights of the holders of such shares will terminate,
except the right to receive the redemption price.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company, then, before any distribution or payment shall be
made to the holders of any Common Stock or any other class or series of capital
stock of the Company ranking junior to the Preferred Stock in the distribution
of assets upon any liquidation, dissolution or winding up of the Company, the
holders of each series of Preferred Stock

shall be entitled to receive out of assets of the Company legally available for
distribution to stockholders liquidating distributions in the amount of the
liquidation preference per share, if any, set forth in the applicable Prospectus
Supplement, plus an amount equal to all dividends accrued and unpaid thereon
(which shall not include any accumulation in respect of unpaid noncumulative
dividends for prior dividend periods). After payment of the full amount of the
liquidating distributions to which they are entitled, the holders of Preferred
Stock will have no right or claim to any of the remaining assets of the Company.
In the event that, upon any such voluntary or involuntary liquidation,
dissolution or winding up, the available assets of the Company are insufficient
to pay the amount of the liquidating distributions on all outstanding shares of
Preferred Stock and the corresponding amounts payable on all shares of other
classes or series of capital stock of the Company ranking on a parity with the
Preferred Stock in the distribution of assets, then the holders of the Preferred
Stock and all other such classes or series of capital stock shall share ratably
in any such distribution of assets in proportion to the full liquidating
distributions to which they would otherwise be respectively entitled.
 
     If liquidating distributions shall have been made in full to all holders of
Preferred Stock, the remaining assets of the Company shall be distributed among
the holders of any other classes or series of capital stock ranking junior to
the Preferred Stock upon liquidation, dissolution or winding up, according to
their respective rights and preferences and in each case according to their
respective number of shares. For such purposes, the consolidation or merger of
the Company with or into any other corporation, trust or entity, or the sale,
lease or conveyance of all or substantially all of the property or business of
the Company, shall not be deemed to constitute a liquidation, dissolution or
winding up of the Company.
 
VOTING RIGHTS
 
     Holders of the Preferred Stock will not have any voting rights, except as
set forth below or as otherwise from time to time required by law or as
indicated in the applicable Prospectus Supplement.
 
     Unless provided otherwise for any series of Preferred Stock, so long as any
shares of Preferred Stock of a series remain outstanding, the Company will not,
without the affirmative vote or consent of the holders of at least two-thirds of
the shares of such series of Preferred Stock outstanding at the time, given in
person or by proxy, either in writing or at a meeting (such series voting
separately as a class), (i) authorize or create, or increase the authorized or
issued amount of, any class or series of capital stock ranking prior to such
series of Preferred Stock with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up or reclassify
any authorized capital stock of the Company into such shares, or create,
authorize or issue any obligation or security convertible into or evidencing the
right to purchase any such shares; or (ii) amend, alter or repeal the provisions
of the Company's Articles of Incorporation or the Designating Amendment for such
series of Preferred Stock, whether by merger, consolidation or otherwise (an
"Event"), so as to materially and adversely affect any right, preference,
privilege or voting power of such series of Preferred Stock or the holders
thereof; provided, however, with respect to the occurrence of any of the Events
set forth in (ii) above, so long as the Preferred Stock remains outstanding with
the terms thereof materially unchanged, taking into account that upon the
occurrence of an Event the Company may not be the surviving entity, the
occurrence of any such Event shall not be deemed to materially and adversely
affect such rights, preferences, privileges or voting power of holders of
Preferred Stock, and provided further that (A) any increase in the amount of the
authorized Preferred Stock or the creation or issuance of any other series of
Preferred Stock, or (B) any increase in the amount of authorized shares of such
series or any other series of Preferred Stock, in each case ranking on a parity
with or junior to the Preferred Stock of such series with respect to payment of
dividends or the distribution of assets upon liquidation, dissolution or winding
up, shall not be deemed to materially and adversely affect such rights,
preferences, privileges or voting powers.
 
     The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required shall
be effected, all outstanding shares of such series of Preferred Stock shall have
been redeemed or called for redemption and sufficient funds shall have been
deposited in trust to effect such redemption.

CONVERSION RIGHTS
 
     The terms and conditions, if any, upon which any series of Preferred Stock
is convertible into Common Stock will be set forth in the applicable Prospectus
Supplement relating thereto. Such terms will include the number of shares of
Common Stock into which the shares of Preferred Stock are convertible, the
conversion price or rate (or manner of calculation thereof), the conversion
period, provisions as to whether conversion will be at the option of the holders
of the Preferred Stock or the Company, the events requiring an adjustment of the
conversion price and provisions affecting conversion in the event of the
redemption of such series of Preferred Stock.
 
RESTRICTIONS ON OWNERSHIP
 
     For the Company to qualify as a REIT under the Internal Revenue Code of
1986, as amended (the "Code"), not more than 50% in value of its outstanding
capital stock may be owned, directly or indirectly, by five or fewer individuals
(as defined in the Code to include certain entities) during the last half of a
taxable year. To assist the Company in meeting this requirement, the Company may
take certain actions to limit the beneficial ownership, directly or indirectly,
by a single person of the Company's outstanding equity securities, including any
Preferred Stock of the Company. Therefore, the Designating Amendment for each
series of Preferred Stock may contain provisions restricting the ownership and
transfer of the Preferred Stock. The applicable Prospectus Supplement will
specify any additional ownership limitation relating to a series of Preferred
Stock. See "Restrictions on Transfers of Capital Stock."
 
TRANSFER AGENT
 
     The transfer agent and registrar for the Preferred Stock will be set forth
in the applicable Prospectus Supplement.
 
                          DESCRIPTION OF COMMON STOCK
 
     The description of the Company's Common Stock set forth below does not
purport to be complete and is qualified in its entirety by reference to the
Company's Articles of incorporation and Bylaws, as in effect from time to time.
 
GENERAL
 
     Under the Articles of Incorporation, the Company has authority to issue 100
million shares of Common Stock, par value $.01 per share. Under Maryland law,
stockholders generally are not responsible for the corporation's debts or
obligations. At April 3, 1997, the Company had outstanding 23,078,821 shares of
Common Stock.
 
TERMS
 
     Subject to the preferential rights of any other class or series of stock
and to the provisions of the Company's Articles of Incorporation regarding
Excess Stock, holders of shares of Common Stock will be entitled to receive
dividends on shares of Common Stock if, as and when authorized and declared by
the Board of Directors of the Company out of assets legally available therefor
and to share ratably in the assets of the Company legally available for
distribution to its stockholders in the event of its liquidation, dissolution or
winding-up after payment of, or adequate provision for, all known debts and
liabilities of the Company.
 
     Subject to the provisions of the Company's Articles of Incorporation
regarding Excess Stock, each outstanding share of Common Stock entitles the
holder to one vote on all matters submitted to a vote of stockholders, including
the election of Directors and, except as otherwise required by law or except as
provided with respect to any other class or series of stock, the holders of
Common Stock will possess the exclusive voting power. The Company's Board of
Directors is divided into three classes. The members of each class serve for a
term of three years. The terms for the three classes are staggered such that the
term of only one class of directors expires each year. There is no cumulative
voting in the election of Directors, which means that the holders of a majority
of the outstanding shares of Common Stock can elect all of the Directors then
 
                                       20
<PAGE>   22
 
standing for election, and the holders of the remaining shares of Common Stock
will not be able to elect any Directors.
 
     Holders of Common Stock have no conversion, sinking fund or redemption
rights, or preemptive rights to subscribe for any securities of the Company.
 
     Subject to the provisions of the Company's Articles of Incorporation
regarding Excess Stock, all shares of Common Stock will have equal dividend,
distribution, liquidation and other rights, and will have no preference,
appraisal or exchange rights.
 
     Pursuant to the MGCL, a corporation generally cannot dissolve, amend its
Articles of Incorporation, merge, sell all or substantially all of its assets,
engage in a share exchange or engage in similar transactions outside the
ordinary course of business unless approved by the affirmative vote of
stockholders holding at least two-thirds of the shares entitled to vote on the
matter unless a lesser percentage (but not less than a majority of all of the
votes to be cast on the matter) is set forth in the corporation's Articles of
Incorporation. The Company's Articles of Incorporation provide that such
transactions, with the exception of an amendment of the Articles of
Incorporation affecting restrictions on transfer, can be effected by a vote of a
majority of the shares entitled to vote on such matters.
 
     Provisions of the Company's Articles of Incorporation described below under
"Restrictions on Transfers of Capital Stock," together with other provisions of
the Company's Articles of Incorporation and the MGCL may discourage a change in
control and limit the opportunity for stockholders to receive a premium for
their Common Stock.
 
RESTRICTIONS ON OWNERSHIP
 
     For the Company to qualify as a REIT under the Code, not more than 50% in
value of its outstanding capital stock may be owned, directly or indirectly, by
five or fewer individuals (as defined in the Code to include certain entities)
during the last half of a taxable year. To assist the Company in meeting this
requirement, the Company may take certain actions to limit the beneficial
ownership, directly or indirectly, by a single person of the Company's
outstanding equity securities. See "Restrictions on Transfers of Capital Stock."
 
TRANSFER AGENT
 
     The transfer agent and registrar for the Common Stock is First Union
National Bank of North Carolina.
 
                   RESTRICTIONS ON TRANSFERS OF CAPITAL STOCK
 
     For the Company to qualify as a REIT under the Code, among other things,
not more than 50% in value of its outstanding capital stock may be owned,
directly or indirectly, by five or fewer individuals (defined in the Code to
include certain entities) during the last half of a taxable year (other than the
first year) (the "Five or Fewer Test"), and such capital stock must be
beneficially owned by 100 or more persons during at least 335 days of a taxable
year of 12 months (other than the first year) or during a proportionate part of
a shorter taxable year. See "Federal Income Tax Considerations." In order to
protect the Company against the risk of losing its status as a REIT on account
of a concentration of ownership among its stockholders, the Articles of
Incorporation, subject to certain exceptions, provide that no holder who is an
individual may own, or be deemed to own by virtue of the attribution provisions
of the Code, more than 9.8% (the "Ownership Limit") of the Company's capital
stock. Pursuant to the Code, certain types of entities, such as pension trusts
qualifying under Section 401(a) of the Code, United States investment companies
registered under the Investment Company Act of 1940 and corporations will be
looked-through for the purposes of the Five or Fewer Test. The Company's
Articles of Incorporation limits such entities to holding no more than 15% of
the aggregate value of the Company's shares of capital stock (the "Look-Through
Ownership Limit"). Any transfer of capital stock or any security convertible
into capital stock that would create a direct or indirect ownership of capital
stock in excess of the Ownership Limit or the Look-Through Ownership Limit or
that would result in the disqualification of the Company as a REIT, including
any transfer that results in the capital
 
                                       21
<PAGE>   23
 
stock being owned by fewer than 100 persons or results in the Company being
"closely held" within the meaning of Section 856(h) of the Code, shall be null
and void, and the intended transferee will acquire no rights to the capital
stock. The Board of Directors in its sole discretion may waive the Ownership
Limit or the Look-Through Ownership Limit if evidence satisfactory to the Board
of Directors and the Company's tax counsel is presented that the changes in
ownership will not then or in the future jeopardize the Company's status as a
REIT and the Board of Directors otherwise decides that such action is in the
best interests of the Company. The foregoing restrictions on transferability and
ownership will not apply if the Board of Directors determines that it is no
longer in the best interests of the Company to attempt to qualify, or to
continue to qualify, as a REIT.
 
     Capital stock owned, or deemed to be owned, or transferred to a stockholder
in excess of the Ownership Limit or the Look-Through Ownership Limit will
automatically be converted into shares of Excess Stock that will be transferred,
by operation of law, to the Company as trustee of a trust for the exclusive
benefit of the transferees to whom such capital stock may be ultimately
transferred without violating the Ownership Limit or the Look-Through Ownership
Limit. While held in trust, the Excess Stock will not be considered for purposes
of any stockholder vote or the determination of a quorum for such vote and,
except upon liquidation, will not be entitled to participate in distributions.
Any distribution paid on Excess Stock, prior to the discovery by the Company
that capital stock has been transferred in violation of the Ownership Limit or
the Look-Through Ownership Limit, shall be repaid to the Company upon demand.
Shares of Excess Stock are not treasury stock, but rather constitute a separate
class of issued and outstanding stock of the Company. The original
transferee-stockholder may, at any time while the shares of Excess Stock are
held by the Company in trust, transfer the interest in the trust representing
the Excess Stock to any individual whose ownership of the capital stock
converted into such Excess Stock would be permitted under the Ownership Limit or
the Look-Through Ownership Limit, at a price not in excess of (i) the price paid
by the original transferee-stockholder for the capital stock that was converted
into Excess Stock, or (ii) if the original transferee-stockholder did not give
value for such shares (e.g. the capital stock was received through a gift,
devise or other transaction), the average closing price for the class of shares
from which such shares of Excess Stock were converted for the ten days
immediately preceding such sale or gift. Immediately upon the transfer to the
permitted transferee, the Excess Stock will automatically be converted into
capital stock of the class from which it was converted. If the foregoing
transfer restrictions are determined to be void or invalid by virtue of any
legal decision, statute, rule or regulation, then the intended transferee of any
Excess Stock may be deemed, at the option of the Company, to have acted as an
agent on behalf of the Company in acquiring the Excess Stock and to hold the
Excess Stock on behalf of the Company.
 
     In addition, the Company will have the right, for a period of 90 days
during the time any shares of Excess Stock are held by the Company in trust, to
purchase all or any portion of the Excess Stock from the original
transferee-stockholder for the lesser of (i) the price initially paid for the
capital stock by the original transferee-stockholder, or if the original
transferee-stockholder did not give value for such shares (e.g., the shares were
received through a gift, devise or other transaction), the average closing price
for the class of capital stock from which such shares of Excess Stock were
converted for the ten days immediately preceding such sale or gift, and (ii) the
average closing price for the class of such shares of Excess Stock were
converted for the ten trading days immediately preceding the date the Company
elects to purchase such shares. The 90-day period begins on the date notice is
received of the violative transfer if the original transferee-stockholder gives
notice to the Company of the transfer or, if no such notice is given, the date
the Board of Directors determines that a violative transfer has been made.
 
     These restrictions will not preclude settlement of transactions through the
New York Stock Exchange.
 
     Each stockholder shall, upon demand, be required to disclose to the Company
in writing any information with respect to the direct, indirect and constructive
ownership of the Company's capital stock as the Board of Directors deems
necessary to comply with the provisions of the Code applicable to REITs, to
comply with the requirements of any taxing authority or governmental agency or
to determine any such compliance.
 
                                       22
<PAGE>   24
 
     The Ownership Limit and the Look-Through Ownership Limit may have the
effect of precluding acquisition of control of the Company unless the Board of
Directors determines that maintenance of REIT status is no longer in the best
interests of the Company.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
     The Company believes it has operated, and the Company intends to continue
to operate, in such a manner as to qualify as a REIT under the Code, but no
assurance can be given that it will at all times so qualify.
 
     The provisions of the Code pertaining to REITs are highly technical and
complex. The following is a brief and general summary of the material federal
income tax considerations of an investment in the Company's Securities to the
extent those considerations relate to the taxation of the Company. To the extent
such considerations relate to the tax treatment of particular Securities, they
will be addressed in the applicable Prospectus Supplement. For the particular
provisions that govern the federal income tax treatment of the Company and its
stockholders, reference is made to Sections 856 through 860 of the Code and the
regulations thereunder. The following summary is qualified in its entirety by
those Sections of the Code and the regulations thereunder.
 
     The statements in this discussion are based on current provisions of the
Code, Treasury Regulations promulgated under the Code, the legislative history
of the Code, existing administrative rulings and practices of the Service, and
judicial decisions. No assurance can be given that future legislative, judicial,
or administrative actions or decisions, which may be retroactive in effect, will
not affect the accuracy of any statements in this Prospectus with respect to the
transactions entered into or contemplated prior to the effective date of such
changes.
 
     EACH INVESTOR IS ADVISED TO CONSULT HIS OWN TAX ADVISOR REGARDING THE
SPECIFIC TAX CONSEQUENCE TO HIM OR HER OF AN INVESTMENT IN THE COMPANY'S
SECURITIES.
 
     Under the Code, if certain requirements are met in a taxable year, a REIT
generally will not be subject to federal income tax with respect to income that
it distributes to its stockholders. However, the Company may be subject to
federal income tax under certain circumstances including taxes at regular
corporate rates on any undistributed REIT taxable income, the "alternative
minimum tax" on its items of tax preference, and taxes imposed on income and
gain generated by certain extraordinary transactions. If the Company fails to
qualify during any taxable year as a REIT, unless certain relief provisions are
available, it will be subject to tax (including any applicable alternative
minimum tax) on its taxable income at regular corporate rates, which could have
a material adverse effect upon its stockholders.
 
     In addition to meeting a number of technical requirements, including
requirements regarding distributions to shareholders, diversification of
ownership and record keeping, to qualify as a REIT the Company must meet certain
tests regarding the nature of its assets and its gross income. The Company is
largely restricted under these tests to holding "real estate assets" (as defined
in the Code) for investment (and not for resale) and relatively small amounts of
investment securities. Accordingly, the Company's ability to diversify its
holdings outside of investments in real estate is limited. The requirements of
the statutory tests also impose certain requirements on the Company's leases
with its tenants, including restrictions on the Company's ability to provide
noncustomary services to its tenants. Because the Company's proportionate share
of the assets and items of income of the Operating Partnership and its
subsidiaries are treated as assets and gross income of the Company, the same
restrictions apply to the operations and investments of the Operating
Partnership and its subsidiaries. Further, changes in law, or in the
interpretation of the law, may change the nature and effect of these
restrictions or add additional restrictions to the manner in which the Company
conducts its business.
 
     In the opinion of Goodwin, Procter & Hoar LLP, counsel to the Company,
commencing with the taxable year ending December 31, 1994, the Company has been
organized and operated in conformity with the requirements for qualification and
taxation as a REIT under the Code, and the Company's proposed method of
operation will enable it to continue to meet the requirements for qualification
and taxation as a REIT under
 
                                       23
<PAGE>   25
 
the Code. Investors should be aware, however, that opinions of counsel are not
binding upon the Service or any court. Moreover, Goodwin, Procter & Hoar LLP's
opinion is based on various assumptions and is conditioned upon certain
representations made by the Company as to factual matters, including
representations regarding the nature of the Company's properties, and the future
conduct of the Company's business. The Company's qualification and taxation as a
REIT depends upon the Company's ability to meet on a continuing basis, through
actual annual operating results, the distribution levels, stock ownership, and
other various qualification tests imposed under the Code. Goodwin, Procter &
Hoar LLP will not review the Company's compliance with those tests on a
continuing basis. Accordingly, no assurance can be given that the actual results
of the Company's operation for any particular taxable year will satisfy such
requirements.
 
     Investors are urged to consult their own tax advisors with respect to the
appropriateness of an investment in the Securities offered hereby and with
respect to the tax consequences arising under federal law and the laws of any
state, municipality or other taxing jurisdiction, including tax consequences
resulting from such investor's own tax characteristics. In particular, foreign
investors should consult their own tax advisors concerning the tax consequences
of an investment in the Company, including the possibility of United States
income tax withholding on Company distributions.
 
                              PLAN OF DISTRIBUTION
 
     The Company and the Operating Partnership may sell Securities through
underwriters or dealers, directly to one or more purchasers, through agents or
through a combination of any such methods of sale.
 
     The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices, or at negotiated prices.
 
     In connection with the sale of Securities, underwriters or agents may
receive compensation from the Company, from the Operating Partnership or from
purchasers of Securities, for whom they may act as agents, in the form of
discounts, concessions or commissions. Underwriters may sell Securities to or
through dealers, and such dealers may receive compensation in the form of
discounts, concessions or commissions from the underwriters and/or commissions
from the purchasers for whom they may act as agents. Underwriters, dealers, and
agents that participate in the distribution of Securities may be deemed to be
underwriters under the Securities Act, and any discounts or commissions they
receive from the Company or the Operating Partnership, and any profit on the
resale of Securities they realize may be deemed to be underwriting discounts and
commissions under the Securities Act. Any such underwriter or agent will be
identified, and any such compensation received from the Company or the Operating
Partnership will be described, in the applicable Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, each
series of Securities will be a new issue with no established trading market,
other than the Common Stock which is listed on the NYSE. Any shares of Common
Stock sold pursuant to a Prospectus Supplement will be listed on the NYSE,
subject to official notice of issuance. The Operating Partnership or the Company
may elect to list any series of Debt Securities or Preferred Stock on an
exchange, but is not obligated to do so. It is possible that one or more
underwriters may make a market in a series of Securities, but will not be
obligated to do so and may discontinue any market making at any time without
notice. Therefore, no assurance can be given as to the liquidity of, or the
trading market for, any series of Debt Securities or Preferred Stock.
 
     Until the distribution of the Securities is completed, rules of the
Commission may limit the ability of any underwriters and selling group members
to bid for and purchase the Securities. As an exception to these rules,
underwriters are permitted to engage in certain transactions that stabilize the
price of the Securities. Such transactions consist of bids or purchases for the
purpose of pegging, fixing or maintaining the price of the Securities.
 
     If any underwriters create a short position in the Securities in connection
with an offering, i.e., if they sell more Securities than are set forth on the
cover page of the applicable Prospectus Supplement, the underwriters may reduce
that short position by purchasing Securities in the open market.
 
                                       24
<PAGE>   26
 
     The lead underwriters may also impose a penalty bid on certain other
underwriters and selling group members participating in an offering. This means
that if the lead underwriters purchase Securities in the open market to reduce
the underwriters' short position or to stabilize the price of the Securities,
they may reclaim the amount of any selling concession from the underwriters and
selling group members who sold those Securities as part of the offering.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security before the distribution is completed.
 
     Neither the Company nor the Operating Partnership makes any representation
or prediction as to the direction or magnitude of any effect that the
transactions described above might have on the price of the Securities. In
addition, neither the Company nor the Operating Partnership makes any
representation that underwriters will engage in such transactions or that such
transactions, once commenced, will not be discontinued without notice.
 
     Under agreements into which the Company or the Operating Partnership may
enter, underwriters, dealers and agents who participate in the distribution of
Securities may be entitled to indemnification by the Company or the Operating
Partnership against certain liabilities, including liabilities under the
Securities Act.
 
     Underwriters, dealers and agents may engage in transactions with, or
perform services for, or be tenants of, the Company or the Operating Partnership
in the ordinary course of business.
 
     If so indicated in the applicable Prospectus Supplement, the Company or the
Operating Partnership will authorize underwriters or other persons acting as the
Company's or the Operating Partnership's agents to solicit offers by certain
institutions to purchase Securities from the Company pursuant to contracts
providing for payment and delivery on a future date. Institutions with which
such contracts may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions and others, but in all cases such institutions must be approved by
the Company or the Operating Partnership, as the case may be. The obligations of
any purchaser under any such contract will be subject to the condition that the
purchase of the Securities shall not at the time of delivery be prohibited under
the laws of the jurisdiction to which such purchaser is subject. The
underwriters and such other agents will not have any responsibility in respect
of the validity or performance of such contracts.
 
     If so indicated in the applicable Prospectus Supplement, the Operating
Partnership will authorize underwriters or other persons acting as the Operating
Partnership's agents to solicit offers by certain institutions to purchase Debt
Securities from the Operating Partnership at the public offering price set forth
in such Prospectus Supplement pursuant to delayed delivery contracts
("Contracts") providing for payment and delivery on the date or dates stated in
such Prospectus Supplement. Each Contract will be for an amount not less than,
and the aggregate principal amount of Debt Securities sold pursuant to Contracts
shall be not less nor more than, the respective amounts stated in the applicable
Prospectus Supplement. Institutions with whom Contracts, when authorized, may be
made include commercial and savings banks, insurance companies, pension funds,
investment companies, educational and charitable institutions, and other
institutions but will in all cases be subject to the approval of the Operating
Partnership. Contracts will not be subject to any conditions except (i) the
purchase by an institution of the Debt Securities covered by its Contracts shall
not at the time of delivery be prohibited under the laws of any jurisdiction in
the United States to which such institution is subject, and (ii) if the Debt
Securities are being sold to underwriters, the Operating Partnership shall have
sold to such underwriters the total principal amount of the Debt Securities less
the principal amount thereof covered by Contracts.
 
     In order to comply with the securities laws of certain states, if
applicable, the Securities offered hereby will be sold in such jurisdictions
only through registered or licensed brokers or dealers. In addition, in certain
states Securities may not be sold unless they have been registered or qualified
for sale in the applicable state or an exemption from the registration or
qualification requirement is available and is complied with.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
     The Company's Articles of Incorporation and Bylaws limit the liability of
the Company's directors and officers to the Company and its stockholders to the
fullest extent permitted from time to time by Maryland law. Maryland law
presently permits the liability of directors and officers to a corporation or
its stockholders for money damages to be limited, except (i) to the extent that
it is proved that the director or officer actually received an improper benefit
or profit; or (ii) if a judgment or other final adjudication is entered in a
proceeding based on a finding that the director's or officer's action or failure
to act was the result of active and deliberate dishonesty and was material to
the cause of action adjudicated in the proceeding. This provision does not limit
the ability of the Company or its stockholders to obtain other relief, such as
an injunction or rescission.
 
     The Company's Articles of Incorporation and Bylaws also require the Company
to indemnify its directors, officers and certain other parties to the fullest
extent permitted from time to time by Maryland law. Maryland law permits a
corporation to indemnify its directors, officers and certain other parties
against judgements, penalties, fines, settlements and reasonable expenses
actually incurred by them in connection with any proceeding to which they may be
made a party by reason of their service to or at the request of the corporation,
unless it is established that (i) the act or omission was committed in bad faith
or was the result of active and deliberate dishonesty; (ii) the indemnified
party actually received an improper personal benefit; or (iii) in the case of
any criminal proceeding, the indemnified party had reasonable cause to believe
that the act or omission was unlawful.
 
     The Operating Partnership's partnership agreement limits the liability of
the general partner and its officers and directors for losses sustained or
liabilities incurred as a result of errors in judgment or of any act or omission
if the general partner acted in good faith. The agreement also requires the
Operating Partnership to indemnify the general partner, directors, trustees and
officers of the Operating Partnership and the general partner and certain other
parties to the fullest extent permitted from time to time by Delaware law.
 
     Pursuant to the authority granted in the Company's Articles of
Incorporation and Bylaws and the Operating Partnership's partnership agreement,
the Company and the Operating Partnership have entered into indemnification
agreements with each of the Company's directors and executive officers. The
indemnification agreements require, among other matters, that the Company
indemnify its executive officers and directors to the fullest extent permitted
by law and advance to such officers and directors all related expenses, subject
to reimbursement if it is subsequently determined that indemnification is not
permitted. The Company must also indemnify and advance all expenses incurred by
such officers and directors seeking to enforce their rights under the
indemnification agreements and may cover such officers and directors under the
Company's
 
                                      II-1
<PAGE>   30
 
directors' and officers' liability insurance. Although the form of
indemnification agreement offers substantially the same scope of coverage
afforded by law, it provides assurance to directors and officers that
indemnification will be available, because, as a contract, it cannot be modified
unilaterally in the future by the Board of Directors or the Stockholders to
eliminate the rights it provides.

  ITEM 17.  UNDERTAKINGS.
 
     (a) The undersigned registrants hereby undertake:
 
        (1) To file, during any period in which offers or sales are being made,
            a post-effective amendment to this registration statement:
 
           (i) To include any prospectus required by Section 10(a)(3) of the
               Securities Act;
 
           (ii) To reflect in the prospectus any facts or events arising after
                the effective date of the registration statement (or the most
                recent post-effective amendment thereof) which, individually or
                in the aggregate, represent a fundamental change in the
                information set forth in the registration statement; and
 
           (iii) To include any material information with respect to the plan of
                 distribution not previously disclosed in the registration
                 statement or any material change to such information in the
                 registration statement;
 
     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) herein do not
     apply if the information required to be included in a post-effective
     amendment by those paragraphs is contained in periodic reports filed by the
     undersigned registrants pursuant to Section 13 or Section 15(d) of the
     Exchange Act that are incorporated by reference in the registration
     statement;
 
        (2) That, for the purpose of determining any liability under the
            Securities Act, each such post-effective amendment shall be deemed
            to be a new registration statement relating to the securities
            offered therein, and the offering of such securities at that time
            shall be deemed to be the initial bona fide offering thereof; and
 
        (3) To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering.
 
     (b) The registrants hereby undertake that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the respective
registrant's annual report pursuant to Section 13(a) or 15(d) of the
 
                                      II-2
<PAGE>   31
 
Securities Exchange Act of 1934 that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrants pursuant to the provisions described under Item 15 above, or
otherwise, the registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the respective registrant of expenses incurred or paid by a
director, officer, or controlling person of such registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, such
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.
 
     (d) The undersigned registrant Summit Properties Partnership, L.P. hereby
undertakes to file an application for the purpose of determining the eligibility
of the trustee to act under subsection (a) of Section 310 of the Trust Indenture
Act in accordance with the rules and regulations prescribed by the Commission
under Section 305(b)(2) of the Act.

more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,

action embodied therein and evidenced thereby) are herein sometimes referred to

Trustee and the Partnership


                                       11
<PAGE>   18
and any agent of the Trustee or the Partnership, if made in the manner provided
in this Section. The record of any meeting of Holders of Securities shall be
proved in the manner provided in Section 1506.

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

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

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

            (e) If the Partnership shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Partnership may, at its option, in or pursuant to a
Board Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Partnership shall have no obligation to do
so. Notwithstanding TIA Section 316(c), such record date shall be the record
date specified in or pursuant to such Board Resolution, which shall be a date
not earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record


                                       12
<PAGE>   19
date shall be deemed to be Holders for the purposes of determining whether
Holders of the requisite proportion of Outstanding Securities have authorized or
agreed or consented to such request, demand, authorization, direction, notice,
consent, waiver or other Act, and for that purpose the Outstanding Securities
shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than eleven months after the record date.

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

      SECTION 105. Notices, etc., to Trustee and Partnership. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Partnership shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing to or with the Trustee at ____________________; or

                  (2) the Partnership by the Trustee or by any Holder shall be
      sufficient for every purpose hereunder (unless otherwise herein expressly
      provided) if in writing and mailed, first class postage prepaid, to the
      Partnership, c/o the Company, addressed to it at the address of its
      principal office specified in the first paragraph of this Indenture or at
      any other address previously furnished in writing to the Trustee by the
      Partnership, Attention: Chief Financial Officer (with a copy to the
      Partnership's general counsel), or

                  (3) either the Trustee or the Partnership, by the other party,
      shall be sufficient for every purpose hereunder if given by facsimile
      transmission, receipt confirmed by telephone followed by an original copy
      delivered by guaranteed overnight courier; if to the Trustee at facsimile
      number (___) ________; and if to the Partnership at facsimile number (704)

notice of any event to Holders of Registered Securities by the Partnership or
the Trustee, such notice shall be sufficiently given (unless otherwise herein

<PAGE>   20
the earliest date, if any, prescribed for the giving of such notice. In any case
where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

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

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

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

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

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

Indenture may be executed in any number of counterparts, each of which so
executed shall be deemed to be an original, but all such counterparts shall
together constitute but one and the same Indenture. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

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

      SECTION 109. Severability Clause. In case any provision in this Indenture

shall be governed by and construed in accordance with the law of the [State of
New York]. This Indenture is subject to the provisions of the TIA that are

Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or
Maturity of any Security or the last date on which a Holder has the right to
exchange a Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or any Security or coupon
other than a provision in the Securities of any series which specifically states
that such provision shall apply in lieu hereof), payment of interest or any
Additional Amounts or principal (and premium, if any) or exchange of such
security need not be made at such Place of Payment on such date, but (except as
otherwise provided in the supplemental indenture with respect to such Security)
may be made on the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date, Redemption
Date, Repayment Date or sinking fund payment date, or at the Stated Maturity or
Maturity, or on such last day for exchange, provided that no interest shall
accrue on the amount so payable for the period from and after such Interest
Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated

any obligation or indebtedness relating to the principal of, or premium or

rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such
liability being expressly waived and released by the acceptance of the
Securities by the Holders and as part of the consideration for the issue of the
Securities.

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

with Section 301, shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture or any indenture supplemental hereto, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements placed thereon as the Partnership may deem appropriate and as are
not inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange on which the Securities may be
listed, or to conform to usage.

      Unless otherwise specified as contemplated by Section 301, Bearer

or coupons.

      SECTION 202. Form of Trustee's Certificate of Authentication. Subject to
Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

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

                                          [NAME OF TRUSTEE]
                                           as Trustee


                                          By
                                             ---------------------------------
                                                  Authorized Signatory

      SECTION 203. Securities Issuable in Global Form. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders thereof, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner or by such Person or Persons as shall be
specified therein or in the Partnership Order to be delivered to the Trustee
pursuant to Section 303 or 304. Subject to the provisions of Section 303 and, if
applicable, Section 304, the Trustee shall deliver and redeliver any Global
Security in permanent global form in the manner and upon instructions given by
the Person or Persons specified therein or in the applicable Partnership Order.
If a Partnership Order pursuant to Section 303 or 304 has been, or
simultaneously is, delivered, any instructions by the Partnership with respect
to endorsement or delivery or redelivery of a Global Security shall be in
writing but need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel.

      The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Partnership and the Partnership delivers to the Trustee the Global
Security together with written instructions (which need not comply with Section
102 and need not be accompanied by an


                                       17
<PAGE>   24
Opinion of Counsel) with regard to the reduction in the principal amount of
Securities represented thereby, together with the written statement contemplated
by the last sentence of Section 303.

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

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

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

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

<PAGE>   28
                  (22) whether and under what circumstances the Partnership will
      pay Additional Amounts as contemplated by Section 1009 on the Securities
      of the series to any Holder who is not a United States person (including
      any modification to the definition of such term) in respect of any tax,
      assessment or governmental charge and, if so, whether the Partnership will
      have the option to redeem such Securities rather than pay such Additional
      Amounts (and the terms of any such option); and

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

      All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

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

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

      SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Partnership by the Chairman of the Board and the President or one of the
Vice Presidents of the Company, as general partner of the Partnership, under its
corporate seal reproduced thereon, and attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
and coupons may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Securities.

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


                                       22
<PAGE>   29
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

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

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

            (i)   an Opinion of Counsel stating that

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

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

<PAGE>   30
                  (c) such Securities, together with any coupons appertaining
            thereto, when completed by appropriate insertions and executed and
            delivered by the Partnership to the Trustee for authentication in
            accordance with this Indenture, authenticated and delivered by the
            Trustee in accordance with this Indenture and issued by the
            Partnership in the manner and subject to any conditions specified in
            such Opinion of Counsel, will constitute legal, valid and legally
            binding obligations of the Partnership, enforceable in accordance
            with their terms, subject to applicable bankruptcy, insolvency,
            fraudulent transfer, reorganization and other similar laws of
            general applicability relating to or affecting the enforcement of
            creditors' rights generally and to general equitable principles; and

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

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

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

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

      No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global Security) shall have been authenticated and delivered
hereunder but never issued and sold by the Partnership, and the Partnership
shall deliver such Security to the Trustee for cancellation as provided in
Section 309 together with a written statement (which need not comply with


                                       24
<PAGE>   31
Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Partnership, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

      SECTION 304. Temporary Securities. Pending the preparation of definitive
Securities of any series, the Partnership may execute, and upon Partnership
Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form, or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as conclusively evidenced by
their execution of such Securities. In the case of Securities of any series,
such temporary Securities may be in global form.

      Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution), if temporary Securities of any series are issued, the
Partnership will cause definitive Securities of that series to be prepared
without unreasonable delay. After the preparation of definitive Securities of
such series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Partnership in a Place of Payment
for that series, without charge to the Holder. Upon surrender for cancellation
of any one or more temporary Securities of any series (accompanied by any
non-matured coupons appertaining thereto), the Partnership shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations;
provided, however, that no definitive Bearer Security shall be delivered in
exchange for a temporary Registered Security; and provided further that a
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303. Until
so exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

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


                                       25
<PAGE>   32
      Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Partnership shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Partnership. On or
after the Exchange Date, such temporary Global Security shall be surrendered by
the Common Depositary to the Trustee, as the Partnership's agent for such
purpose, to be exchanged, in whole or from time to time in part, for definitive
Securities without charge, and the Trustee shall authenticate and deliver, in
exchange for each portion of such temporary Global Security, an equal aggregate
principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such temporary Global Security
to be exchanged. The definitive Securities to be delivered in exchange for any
such temporary Global Security shall be in bearer form, registered form,
permanent global bearer form or permanent global registered form, or any
combination thereof, as specified as contemplated by Section 301, and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof; provided, however, that, unless otherwise specified in such temporary
Global Security, upon such presentation by the Common Depositary, such temporary
Global Security is accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by Euroclear as to the portion of such temporary
Global Security held for its account then to be exchanged and a certificate
dated the Exchange Date or a subsequent date and signed by CEDEL as to the
portion of such temporary Global Security held for its account then to be
exchanged, each in the form set forth in Exhibit A-2 to this Indenture or in
such other form as may be established pursuant to Section 301; and provided
further that definitive Bearer Securities shall be delivered in exchange for a
portion of a temporary Global Security only in compliance with the requirements
of Section 303.

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


                                       26
<PAGE>   33
      Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary Global Security
on an Interest Payment Date for Securities of such series occurring prior to the
applicable Exchange Date shall be payable to Euroclear and CEDEL on such
Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee of a
certificate or certificates in the form set forth in Exhibit B-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit B-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301). Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
the temporary Global Security with respect to which such certification was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners. Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial interest in a temporary Global Security will be
made unless and until such interest in such temporary Global Security shall have
been exchanged for an interest in a definitive Security. Any interest so
received by Euroclear and CEDEL and not paid as herein provided shall be
returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Partnership.

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


                                       27
<PAGE>   34
      Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Partnership in a Place of Payment for that series, the
Partnership shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Registered
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount, bearing a number not contemporaneously outstanding,
and containing identical terms and provisions.

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

      If (but only if) permitted by the applicable Board Resolution and (subject
to Section 303) set forth in the applicable Officers' Certificate, or in any
indenture supplemental hereto, delivered as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Partnership in an amount equal to the face amount of such missing coupon
or coupons, or the surrender of such missing coupon or coupons may be waived by
the Partnership and the Trustee if there is furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security shall surrender to any
Paying Agent any such missing coupon in respect of which such a payment shall
have been made, such Holder shall be entitled to receive the amount of such
payment; provided, however, that, except as otherwise provided in Section 1002,
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest


                                       28
<PAGE>   35
Payment Date or proposed date for payment, as the case may be, and interest or
Defaulted Interest, as the case may be, will not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but will be
payable only to the Holder of such coupon when due in accordance with the
provisions of this Indenture. Whenever any Securities are so surrendered for
exchange, the Partnership shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.

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


                                       29
<PAGE>   36
exchanges may occur during a period beginning at the opening of business 15 days
before any selection of Securities to be redeemed and ending on the relevant
Redemption Date if the Security for which exchange is requested may be among
those selected for redemption; and provided further that no Bearer Security
delivered in exchange for a portion of a permanent Global Security shall be
mailed or otherwise delivered to any location in the United States. If a
Registered Security is issued in exchange for any portion of a permanent Global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, interest or Defaulted Interest,
as the case may be, will not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment, as the case may be, only to the Person to whom interest in respect of
such portion of such permanent Global Security is payable in accordance with the
provisions of this Indenture.

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

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

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Partnership may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any
transfer.

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


                                       30
<PAGE>   37
redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange
any Bearer Security so selected for redemption except that such a Bearer
Security may be exchanged for a Registered Security of that series and like
tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption, or (iv) to issue, register the transfer of or
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

      SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Partnership, together with, in proper cases,
such security or indemnity as may be required by the Partnership or the Trustee
to save each of them or any agent of either of them harmless, the Partnership
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and principal amount, containing
identical terms and provisions and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
the surrendered Security.

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

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

      Upon the issuance of any new Security under this Section , the Partnership
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be


                                       31
<PAGE>   38
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

      Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the
Partnership, whether or not the destroyed, lost or stolen Security and its
coupons, if any, or the destroyed, lost or stolen coupon shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, duly issued hereunder.

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

      SECTION 307. Payment of Interest; Interest Rights Preserved. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Partnership
maintained for such purpose pursuant to Section 1002; provided, however, that
each installment of interest on any Registered Security may at the Partnership's
option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 308, to the
address of such Person as it appears on the Security Register or (ii) transfer
to an account maintained by the payee located inside the United States.

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

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

      In case a Bearer Security of any series is surrendered in exchange for a
Registered Security of such series after the close of business (at an office or
agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be


                                       32
<PAGE>   39
surrendered without the coupon relating to such Interest Payment Date and
interest will not be payable on such Interest Payment Date in respect of the
Registered Security issued in exchange for such Bearer Security, but will be
payable only to the Holder of such coupon when due in accordance with the
provisions of this Indenture.

      Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Partnership, at its election in each case,
as provided in clause (1) or (2) below:

                  (1) The Partnership may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Registered Securities of such
      series (or their respective Predecessor Securities) are registered at the
      close of business on a Special Record Date for the payment of such
      Defaulted Interest, which shall be fixed in the following manner. The
      Partnership shall notify the Trustee in writing of the amount of Defaulted
      Interest proposed to be paid on each Registered Security of such series
      and the date of the proposed payment (which shall not be less than 20 days
      after such notice is received by the Trustee), and at the same time the
      Partnership shall deposit with the Trustee an amount of money in the
      currency or currencies, currency unit or units or composite currency or
      currencies in which the Securities of such series are payable (except as
      otherwise specified pursuant to Section 301 for the Securities of such
      series) equal to the aggregate amount proposed to be paid in respect of
      such Defaulted Interest or shall make arrangements satisfactory to the
      Trustee for such deposit on or prior to the date of the proposed payment,
      such money when deposited to be held in trust for the benefit of the
      Persons entitled to such Defaulted Interest as in this clause provided.
      Thereupon the Trustee shall fix a Special Record Date for the payment of
      such Defaulted Interest which shall be not more than 15 days and not less
      than 10 days prior to the date of the proposed payment and not less than
      10 days after the receipt by the Trustee of the notice of the proposed
      payment. The Trustee shall promptly notify the Partnership of such Special
      Record Date and, in the name and at the expense of the Partnership, shall
      cause notice of the proposed payment of such Defaulted Interest and the
      Special Record Date therefor to be mailed, first-class postage prepaid, to
      each Holder of Registered Securities of such series at his address as it
      appears in the Security Register not less than 10 days prior to such
      Special Record Date. The Trustee may, in its discretion, in the name and
      at the expense of the Partnership, cause a similar notice to be published
      at least once in an Authorized Newspaper in each Place of Payment, but
      such publications shall not be a condition precedent to the establishment
      of such Special Record Date. Notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor having been mailed
      as aforesaid, such Defaulted Interest shall be paid to the Persons in
      whose names the


                                       33
<PAGE>   40
      Registered Securities of such series (or their respective Predecessor
      Securities) are registered at the close of business on such Special Record
      Date and shall no longer be payable pursuant to the following clause (2).
      In case a Bearer Security of any series is surrendered at the office or
      agency in a Place of Payment for such series in exchange for a Registered
      Security of such series after the close of business at such office or
      agency on any Special Record Date and before the opening of business at
      such office or agency on the related proposed date for payment of
      Defaulted Interest, such Bearer Security shall be surrendered without the
      coupon relating to such proposed date of payment and Defaulted Interest
      will not be payable on such proposed date of payment in respect of the
      Registered Security issued in exchange for such Bearer Security, but will
      be payable only to the Holder of such coupon when due in accordance with
      the provisions of this Indenture.

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

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

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

      Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Partnership, the Trustee and any agent of the Partnership
or the Trustee may treat the Holder of any Bearer Security and the Holder of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and neither the
Partnership, the Trustee nor any agent of the Partnership or the Trustee shall
be affected by notice to the contrary.


                                       34
<PAGE>   41
      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 shall be treated by the Partnership,
the Trustee, and any agent of the Partnership or the Trustee as the owner of
such Global Security for all purposes whatsoever. None of the Partnership, the
Trustee, any Paying Agent or the Security Registrar will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

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

      SECTION 309. Cancellation. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose shall be promptly 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
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. If the Partnership shall so acquire any of the Securities, however,
such acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section , except as expressly permitted by this Indenture. Cancelled
Securities and coupons held by the Trustee shall be destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Partnership,
unless the Trustee is otherwise directed by a Partnership Order.

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

                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

      SECTION 401. Satisfaction and Discharge of Indenture. This Indenture shall
upon Partnership Request cease to be of further effect with respect to any
series of Securities specified in such Partnership Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for and any right to receive Additional
Amounts, as provided in Section 1009), and the Trustee, upon receipt of a
Partnership Order, and at the expense of the Partnership, shall execute
instruments in form and substance satisfactory to the Trustee and the
Partnership acknowledging satisfaction and discharge of this Indenture as to
such series when

                  (1)   either

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

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

                        (i) have become due and payable, or

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

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

            and the Partnership, in the case of (i), (ii) or (iii) above, has
            irrevocably deposited or caused to be deposited with the Trustee as
            trust funds in trust for


                                       36
<PAGE>   43
            the purpose an amount in the currency or currencies, currency unit
            or units or composite currency or currencies in which the Securities
            of such series are payable, sufficient to pay and discharge the
            entire indebtedness on such Securities and such coupons not
            theretofore delivered to the Trustee for cancellation, for principal
            (and premium, if any) and interest, and any Additional Amounts with
            respect thereto, 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; and

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

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

      SECTION 402. Application of Trust Funds. Subject to the provisions of the
last paragraph of Section 1003, all money deposited with the Trustee pursuant to
Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities, the coupons and this Indenture, to the payment,
either directly or through any Paying Agent (including the Partnership acting as
its own Paying Agent) as the Trustee may determine, to the Persons entitled
thereto, of the principal (and premium, if any), and any interest and Additional
Amounts for whose payment such money has been deposited with or received by the
Trustee, but such money need not be segregated from other funds except to the
extent required by law.


                             ARTICLE FIVE - REMEDIES

      SECTION 501. Events of Default. "Event of Default," wherever used herein
with respect to any particular series of Securities, means any one of the
following events (whatever the reason for such Event of Default and whether or
not it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):


                                       37
<PAGE>   44
                  (1) default in the payment of any interest upon or any
      Additional Amounts payable in respect of any Security of that series or of
      any coupon appertaining thereto, when such interest, Additional Amounts or
      coupon becomes due and payable, and continuance of such default for a
      period of 30 days; or

                  (2) default in the payment of the principal of (or premium, if
      any, on) any Security of that series when it becomes due and payable at
      its Maturity; or

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

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

                  (5) default under any bond, debenture, note or other evidence
      of indebtedness for money borrowed (except mortgage indebtedness) by the
      Partnership or any of its Subsidiaries in an aggregate principal amount in
      excess of $25,000,000 or under any indenture or instrument under which
      there may be issued or by which there may be secured or evidenced any
      indebtedness for money borrowed (except mortgage indebtedness) by the
      Partnership or any of its Subsidiaries in an aggregate principal amount in
      excess of $25,000,000, whether such indebtedness exists on the date of
      such Indenture or shall thereafter be created, which default shall have
      resulted in such indebtedness becoming or being declared due and payable
      prior to the date on which it would otherwise have become due and payable
      or such obligations being accelerated, without such acceleration having
      been rescinded or annulled; or

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

                        (A) commences a voluntary case,

                        (B) consents to the entry of an order for relief against
         it in an involuntary case,

                        (C) consents to the appointment of a Custodian of it or
         for all or substantially all of its property, or


                                       38
<PAGE>   45
                        (D) makes a general assignment for the benefit of its
         creditors; or

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

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

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

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

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

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

      SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if Securities of
that Series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal as may be specified in the terms thereof) of all the
Securities of that series to be due and payable immediately, by a notice in
writing to the Partnership (and to the Trustee if given by the Holders), and
upon any such declaration such principal or specified portion thereof shall
become immediately due and payable.

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

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


                                       39
<PAGE>   46
      Securities of such series are payable (except as otherwise specified
      pursuant to Section 301 for the Securities of such series):

                        (A) all overdue installments of interest on and any
            Additional Amounts payable in respect of all Outstanding Securities
            of that series and any related coupons,

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

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

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

                  (2) all Events of Default with respect to Securities of that
      series, other than the nonpayment of the principal of (or premium, if any)
      or interest on Securities of that series which have become due solely by
      such declaration of acceleration, have been cured or waived as provided in
      Section 513.

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

      SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Partnership covenants that if:

                  (1) default is made in the payment of any installment of
      interest or Additional Amounts, if any, on any Security of any series and
      any related coupon when such interest or Additional Amount 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 of any series at its Maturity,

then the Partnership will, upon demand of the Trustee, pay to the Trustee, for
the benefit of the Holders of such Securities of such series and coupons, the
whole amount then due and payable on such Securities and coupons for principal
(and premium, if any) and interest and Additional Amounts, with interest upon
any overdue principal (and premium, if any) and, to the extent that payment of
such interest shall be legally enforceable, upon any overdue


                                       40
<PAGE>   47
installments of interest or Additional Amounts, if any, at the rate or rates
borne by or provided for in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

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

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

      SECTION 504. Trustee May File Proofs of Claim. In case of the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Partnership or any other obligor upon the Securities or the property of the
Partnership or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities of any series shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the
Partnership for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise:

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

                        (ii) to collect and receive any moneys or other property
      payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of


                                       41
<PAGE>   48
such series and coupons to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee and any
predecessor Trustee, their agents and counsel, and any other amounts due the
Trustee or any predecessor Trustee under Section 606.

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

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

      SECTION 505. Trustee May Enforce Claims Without Possession of Securities
or Coupons. All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Securities and
coupons in respect of which such judgment has been recovered.

      SECTION 506. Application of Money Collected. Any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium, if any) or interest and any
Additional Amounts, upon presentation of the Securities or coupons, or both, as
the case may be, and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

            FIRST: To the payment of all amounts due the Trustee and any
      predecessor Trustee under Section 606;

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


                                       42
<PAGE>   49
            THIRD:  To the payment of the remainder, if any, to the Partnership.

      SECTION 507. Limitation on Suits. No Holder of any Security of any series
or any related coupon shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless:

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

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

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

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

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

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

      SECTION 508. Unconditional Right of Holders to Receive Principal, Premium,
if any, Interest and Additional Amounts. Notwithstanding any other provision in
this Indenture, the Holder of any Security or coupon shall have the right which
is absolute and unconditional to receive payment of the principal of (and
premium, if any) and (subject to Sections 305 and 307) interest on, and any
Additional Amounts in respect of, such Security or payment of such coupon on the
respective due dates expressed in such Security or coupon (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.


                                       43
<PAGE>   50
      SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Partnership, the Trustee and
the Holders of Securities and coupons shall, subject to any determination in
such proceeding, be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

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

      SECTION 511. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of any Security or coupon to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or coupons, as the
case may be.

      SECTION 512. Control by Holders of Securities. The Holders of not less
than a majority in principal amount of the Outstanding Securities of any series
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee with respect to the Securities of such series,
provided that

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

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

                  (3) the Trustee need not take any action which might involve
      it in personal liability or be unduly prejudicial to the Holders of
      Securities of such series not joining therein.


                                       44
<PAGE>   51
      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Holders.

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

                  (1) in the payment of the principal of (or premium, if any) or
      interest on or Additional Amounts payable in respect of any Security of
      such series or any related coupons, or

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

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

      SECTION 514. Waiver of Usury, Stay or Extension Laws. The Partnership
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Partnership (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

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


                                       45
<PAGE>   52
on or after the respective Stated Maturities expressed in such Security (or, in
the case of redemption, on or after the Redemption Date).


                            ARTICLE SIX - THE TRUSTEE

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

      SECTION 602.  Certain Rights of Trustee.  Subject to the provisions of TIA
Section 315(a) through 315(d):

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

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

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


                                       46
<PAGE>   53
                  (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 of Securities of any series or any related
      coupons pursuant to this Indenture, unless such Holders shall have offered
      to the Trustee security or indemnity reasonably satisfactory to the
      Trustee against the costs, expenses and liabilities which might be
      incurred by it in compliance with such request or direction;

                  (6) the Trustee shall not be bound to make any investigation
      into the facts or matters stated in any resolution, certificate,
      statement, instrument, opinion, report, notice, request, direction,
      consent, order, bond, debenture, note, coupon or other paper or document,
      unless requested in writing so to do by the Holders of not less than a
      majority in aggregate principal amount of the Outstanding Securities of
      any series; provided that, if the payment within a reasonable time to the
      Trustee of the costs, expenses or liabilities likely to be incurred by it
      in the making of such investigation is, in the opinion of the Trustee, not
      reasonably assured to the Trustee by the security afforded to it by the
      terms of this Indenture, the Trustee may require reasonable indemnity
      against such expenses or liabilities as a condition to proceeding; the
      reasonable expenses of every such examination shall be paid by the Holders
      or, if paid by the Trustee, shall be repaid by the Holders upon demand.
      The Trustee, in its discretion, may make such further inquiry or
      investigation into such facts or matters as it may see fit, and, if the
      Trustee shall determine to make such further inquiry or investigation, it
      shall be entitled to examine the books, records and premises of the
      Partnership and the Company, as applicable, relevant to the facts or
      matters that are the subject of its inquiry, personally or by agent or
      attorney;

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

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

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


                                       47
<PAGE>   54
      Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

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

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

      SECTION 605. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Partnership.

      SECTION 606.  Compensation and Reimbursement.  The Partnership agrees:

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

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

                  (3) to indemnify each of the Trustee and any predecessor
      Trustee for, and to hold it harmless against, any loss, liability or
      expense incurred without negligence or bad faith on its part, arising out
      of or in connection with the acceptance


                                       48
<PAGE>   55
      or administration of the trust or trusts hereunder, including the costs
      and expenses of defending itself against any claim or liability in
      connection with the exercise or performance of any of its powers or duties
      hereunder.

      When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

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

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

      SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
Federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section , the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section , it shall resign immediately in the manner and with
the effect hereinafter specified in this Article. Neither the Partnership nor
any Person directly or indirectly controlling, controlled by, or under common
control with the Partnership shall serve as Trustee.

      SECTION 608.  Resignation and Removal; Appointment of Successor.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

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


                                       49
<PAGE>   56
            (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and to the
Partnership.

            (d)   If at any time:

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

                  (2) the Trustee shall cease to be eligible under Section 607
      and shall fail to resign after written request therefor by the Partnership
      or by any Holder of a Security who has been a bona fide Holder of a
      Security for at least six months, or

                  (3) the Trustee shall become incapable of acting or shall be
      adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
      property shall be appointed or any public officer shall take charge or
      control of the Trustee or of its property or affairs for the purpose of
      rehabilitation, conservation or liquidation,

then, in any such case, (i) the Partnership by or pursuant to a Board Resolution
may remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

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


                                       50
<PAGE>   57
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to Securities of such series.

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

      SECTION 609. Acceptance of Appointment by Successor. (a) In case of the
appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Partnership and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Partnership or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee, and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder, subject nevertheless to its claim, if any,
provided for in Section 606.

            (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Partnership,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental
hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall
accept such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall


                                       51
<PAGE>   58
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates; but, on request of the
Partnership or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Partnership
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such rights, powers and trusts
referred to in paragraph (a) or (b) of this Section 609, as the case may be.

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

      SECTION 610. Merger, Conversion, Consolidation or Succession to Business.
Any corporation into which the Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities or coupons shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities or coupons so authenticated with
the same effect as if such successor Trustee had itself authenticated such
Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

      SECTION 611. Appointment of Authenticating Agent. At any time when any of
the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption or
repayment thereof, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the
Partnership. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and


                                       52
<PAGE>   59
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Partnership and shall at
all times be a bank or trust company or corporation organized and doing business
and in good standing under the laws of the United States of America or of any
state or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or state
authorities. If such Authenticating Agent publishes reports of condition at
least annually, pursuant to law or the requirements of the aforesaid supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. In case at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section , such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

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

      An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Partnership. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Partnership. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
such Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Partnership and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

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

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

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

      SECTION 801. Consolidations and Mergers of Partnership and Sales, Leases
and Conveyances Permitted Subject to Certain Conditions. The Partnership may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into, any other


                                       55
<PAGE>   62
entity, provided that in any such case, (1) either the Partnership shall be the
continuing entity, or the successor entity (if other than the Partnership)
formed by or resulting from any such consolidation or merger or which shall have
received the transfer of such assets, shall expressly assume the due and
punctual payment of the principal of (and premium, if any) and any interest
(including all Additional Amounts, if any, payable pursuant to Section 1009) on
all of the Securities, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed by the Partnership by supplemental indenture,
complying with Article Nine hereof, satisfactory to the Trustee, executed and
delivered to the Trustee by such entity and (2) immediately after giving effect
to such transaction and treating any indebtedness which becomes an obligation of
the Partnership or any Subsidiary as a result thereof as having been incurred by

Default, and no event which, after notice or the lapse of time, or both, would
become an Event of Default, shall have occurred and be continuing.

consolidation, merger, sale, lease or conveyance and upon any such assumption by
the successor entity, such successor entity shall succeed to and be substituted
for the Partnership, with the same effect as if it had been named herein as the
party of the first part, and the predecessor entity, except in the event of a
lease, shall be relieved of any further obligation under this Indenture and the
Securities. Such successor entity thereupon may cause to be signed, and may
issue either in its own name or in the name of the Partnership, any or all of
the Securities issuable hereunder which theretofore shall not have been signed
by the Partnership and delivered to the Trustee; and, upon the order of such
successor entity, instead of the Partnership, and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Securities which previously shall have been
signed and delivered by the Partnership to the Trustee for authentication, and
any Securities which such successor entity thereafter shall cause to be signed
and delivered to the Trustee for that purpose. All the Securities so issued
shall in all respects have the same legal rank and benefit under this Indenture
as the Securities theretofore or thereafter issued in accordance with the terms
of this Indenture as though all of such Securities had been issued at the date
of the execution hereof.

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

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

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

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

                  (4) to add to or change any of the provisions of this

      adversely affect the interests of the Holders of Securities of any series
      or any related coupons in any material respect; or

                  (5) to change or eliminate any of the provisions of this
      Indenture, provided that any such change or elimination shall become
      effective only when there is


                                       57
<PAGE>   64
      no Security Outstanding of any series created prior to the execution of
      such supplemental indenture which is entitled to the benefit of such
      provision; or

                  (6) to secure the Securities; or

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

                  (8) to evidence and provide for the acceptance of appointment
      hereunder by a successor Trustee with respect to the Securities of one or
      more series and to add to or change any of the provisions of this
      Indenture as shall be necessary to provide for or facilitate the
      administration of the trusts hereunder by more than one Trustee; or

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

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

      SECTION 902. Supplemental Indentures with Consent of Holders. With the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Securities affected by such supplemental indenture, by Act of said
Holders delivered to the Partnership and the Trustee, the Partnership, when
authorized by or pursuant to a Board Resolution, and the Trustee may enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of

      of interest thereon or any Additional Amounts payable in respect thereof,
      or any premium payable upon the redemption thereof, or change any

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

                             ARTICLE TEN - COVENANTS

      SECTION 1001. Payment of Principal, Premium, if any; Interest and
Additional Amounts. The Partnership covenants and agrees for the benefit of the
Holders of each series of Securities that it will duly and punctually pay the
principal of (and premium, if any) and interest on and any Additional Amounts
payable in respect of the Securities of that series in accordance with the terms
of such series of Securities, any coupons appertaining thereto and this
Indenture. Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, any interest due on and any Additional
Amounts payable in respect of Bearer Securities on or before Maturity, other
than Additional Amounts, if any, payable as provided in Section 1009 in respect
of principal of (or premium, if any, on) such a Security, shall be payable only
upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature. Unless otherwise
specified with respect to Securities of any series pursuant to Section 301, at
the option of the Partnership, all payments of principal may be paid by check to
the registered Holder of the Registered Security or other person entitled
thereto against surrender of such Security.

      SECTION 1002. Maintenance of Office or Agency. If Securities of a series
are issuable only as Registered Securities, the Partnership shall maintain in
each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Partnership in respect of
the Securities of that series and this Indenture may be served. If Securities of
a series are issuable as Bearer Securities, the Partnership will maintain: (A)
in the Borough of Manhattan, The City of New York, an office or agency where any
Registered Securities of


                                       60
<PAGE>   67
that series may be presented or surrendered for payment, where any Registered
Securities of that series may be surrendered for registration of transfer, where
Securities of that series may be surrendered for exchange, where notices and
demands to or upon the Partnership in respect of the Securities of that series
and this Indenture may be served and where Bearer Securities of that series and
related coupons may be presented or surrendered for payment in the circumstances
described in the following paragraph (and not otherwise); (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment
(including payment of any Additional Amounts payable on Securities of that
series pursuant to Section 1009); provided, however, that if the Securities of
that series are listed on any stock exchange located outside the United States
and such stock exchange shall so require, the Partnership will maintain a Paying
Agent for the Securities of that series in any required city located outside the
United States, as the case may be, so long as the Securities of that series are
listed on such exchange; and (C) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series located outside the United States
an office or agency where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange and where notices and demands to or upon the
Partnership in respect of the Securities of that series and this Indenture may
be served. The Partnership will give prompt written notice to the Trustee of the
location, and any change in the location, of each such office or agency. If at
any time the Partnership shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of that
series and the related coupons may be presented and surrendered for payment
(including payment of any Additional Amounts payable on Bearer Securities of
that series pursuant to Section 1009) at the offices specified in the Security,
in London, England, and the Partnership hereby appoints the same as its agent to
receive such respective presentations, surrenders, notices and demands, and the
Partnership hereby appoints the Trustee its agent to receive all such
presentations, surrenders, notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on or Additional
Amounts in respect of Bearer Securities shall be made at any office or agency of
the Partnership in the United States or by check mailed to any address in the
United States or by transfer to an account maintained with a bank located in the
United States; provided, however, that, if the Securities of a series are
payable in Dollars, payment of principal of and any premium and interest on any
Bearer Security (including any Additional Amounts payable on Securities of such
series pursuant to Section 1009) shall be made at the office of the
Partnership's Paying Agent in the Borough of Manhattan, The City of New York, if
(but only if) payment in Dollars of the full amount of such principal, premium,
interest or Additional Amounts, as the case may be, at all offices or agencies
outside the United States maintained for the purpose by the Partnership in
accordance


                                       61

with this Indenture, is illegal or effectively precluded by exchange controls or
other similar restrictions.

      The Partnership may from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Partnership of its obligation to maintain an
office or agency in accordance with the requirements set forth above for
Securities of any series for such purposes. The Partnership will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency. Unless otherwise
specified with respect to any Securities pursuant to Section 301 with respect to
a series of Securities, the Partnership hereby designates as a Place of Payment
for each series of Securities the office or agency of the Partnership in the
Borough of Manhattan, The City of New York, and initially appoints the Trustee
at its Corporate Trust Office as Paying Agent in such city and as its agent to
receive all such presentations, surrenders, notices and demands.

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

      SECTION 1003. Money for Securities Payments to Be Held in Trust. If the
Partnership shall at any time act as its own Paying Agent with respect to any
series of any Securities and any related coupons, it will, on or before each due
date of the principal of (and premium, if any), or interest on or Additional
Amounts in respect of, any of the Securities of that series, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum in the currency
or currencies, currency unit or units or composite currency or currencies in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay the
principal (and premium, if any) or interest or Additional Amounts so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided, and will promptly notify the Trustee of its action or failure
so to act.

      Whenever the Partnership shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium, if any), or interest on or Additional
Amounts in respect of, any Securities of that series, deposit with a Paying
Agent a sum (in the currency or currencies, currency unit or units or composite
currency or currencies described in the preceding paragraph) sufficient to pay
the principal (and premium, if any) or interest or Additional Amounts, so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium


                                       62
<PAGE>   69
or interest or Additional Amounts and (unless such Paying Agent is the Trustee)
the Partnership will promptly notify the Trustee of its action or failure so to
act.

      The Partnership will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will

                  (1) hold all sums held by it for the payment of principal of
      (and premium, if any) or interest on Securities in trust for the benefit
      of the Persons entitled thereto until such sums shall be paid to such
      Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee notice of any default by the Partnership
      (or any other obligor upon the Securities) in the making of any such
      payment of principal (and premium, if any) or interest on the Securities
      of that series; and

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

      The Partnership may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by 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 sums.

      Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Partnership,
in trust for the payment of the principal of (and premium, if any) or interest
on, or any Additional Amounts in respect of, any Security of any series and
remaining unclaimed for two years after such principal (and premium, if any),
interest or Additional Amounts has become due and payable shall be paid to the
Partnership upon Partnership Request or (if then held by the Partnership) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Partnership for payment of
such principal of (and premium, if any) or interest on, or any Additional
Amounts in respect of, any Security, without interest thereon, and all liability
of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Partnership as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Partnership cause to be
published once, in an Authorized Newspaper, notice that such money remains
unclaimed and that, after a date specified therein,


                                       63
<PAGE>   70
which shall not be less than 30 days from the date of such publication, any
unclaimed balance of such money then remaining will be repaid to the
Partnership.

      SECTION 1004. Existence. Subject to Article Eight, the Partnership will do
or cause to be done all things necessary to preserve and keep in full force and
effect its limited partnership existence, all material rights (by agreement of
limited partnership and statute) and material franchises; provided, however,
that the Partnership shall not be required to preserve any such right or
franchise if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the
Partnership.

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

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

      SECTION 1007. Payment of Taxes and Other Claims. The Partnership will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Partnership or any Subsidiary, and (2) all lawful claims for labor, materials
and supplies which, if unpaid, might by law become a lien upon the property of
the Partnership or any Subsidiary; provided, however, that the Partnership shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings.

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


                                       64
<PAGE>   71
      SECTION 1009. Additional Amounts. If any Securities of a series provide
for the payment of Additional Amounts, the Partnership will pay to the Holder of
any Security of such series or any coupon appertaining thereto Additional
Amounts as may be specified as contemplated by Section 301. Whenever in this
Indenture there is mentioned, in any context except in the case of Section
502(l), the payment of the principal of or any premium or interest on, or in
respect of, any Security of any series or payment of any related coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established pursuant to Section 301
to the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof pursuant to such terms and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding Additional Amounts in those provisions hereof where
such express mention is not made.

      Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate, the Partnership will furnish
the Trustee and the Partnership's principal Paying Agent or Paying Agents, if
other than the Trustee, with an Officers' Certificate instructing the Trustee
and such Paying Agent or Paying Agents whether such payment of principal of and
any premium or interest on the Securities of that series shall be made to
Holders of Securities of that series or any related coupons who are not United
States persons without withholding for or on account of any tax, assessment or
other governmental charge described in the Securities of the series. If any such
withholding shall be required, then such Officers' Certificate shall specify by
country the amount, if any, required to be withheld on such payments to such
Holders of Securities of that series or related coupons and the Partnership will
pay to the Trustee or such Paying Agent the Additional Amounts required by the
terms of such Securities. In the event that the Trustee or any Paying Agent, as
the case may be, shall not so receive the above-mentioned certificate, then the
Trustee or such Paying Agent shall be entitled (i) to assume that no such
withholding or deduction is required with respect to any payment of principal or
interest with respect to any Securities of a series or related coupons until it
shall have received a certificate advising otherwise and (ii) to make all
payments of principal and interest with respect to the Securities of a series or
related coupons without withholding or deductions until otherwise advised. The
Partnership covenants to indemnify the Trustee and any Paying Agent for, and to
hold them harmless against, any loss, liability or expense reasonably incurred
without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them or in reliance on any Officers'
Certificate furnished pursuant to this Section or in reliance on the
Partnership's not furnishing such an Officers' Certificate.


                                       65
<PAGE>   72
      SECTION 1010. Waiver of Certain Covenants. The Partnership may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1007, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Partnership and the duties of the
Trustee in respect of any such term, provision or condition shall remain in full
force and effect.


                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

      SECTION 1101. Applicability of Article. Securities of any series which are
redeemable before their Stated Maturity shall be redeemable in accordance with
their terms and (except as otherwise specified as contemplated by Section 301
for Securities of any series) in accordance with this Article.

      SECTION 1102. Election to Redeem; Notice to Trustee. The election of the
Partnership to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution. In case of any redemption at the election of the Partnership
of less than all of the Securities of any series, the Partnership shall, at
least 45 days prior to the giving of the notice of redemption in Section 1104
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities prior to
the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Partnership shall furnish
the Trustee with an Officers' Certificate evidencing compliance with such
restriction.

      SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If less
than all the Securities of any series issued on the same day with the same terms
are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series issued on such date with the same terms
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption 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 and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.


                                       66
<PAGE>   73
      For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Security redeemed or to be redeemed only in part, to the portion of
the principal amount of such Security which has been or is to be redeemed.

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

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

      All notices of redemption shall state:

                  (1)   the Redemption Date,

                  (2) the Redemption Price, accrued interest to the Redemption
      Date payable as provided in Section 1106, if any, and Additional Amounts,
      if any,

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

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

                  (5) that on the Redemption Date the Redemption Price and
      accrued interest to the Redemption Date payable as provided in Section
      1106, if any, will become due and payable upon each such Security, or the
      portion thereof, to be redeemed and, if applicable, that interest thereon
      shall cease to accrue on and after said date,

                  (6) the Place or Places of Payment where such Securities,
      together in the case of Bearer Securities with all coupons appertaining
      thereto, if any, maturing


                                       67
<PAGE>   74
      after the Redemption Date, are to be surrendered for payment of the
      Redemption Price and accrued interest, if any,

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

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

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

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

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

      SECTION 1105. Deposit of Redemption Price. On or prior to any Redemption
Date, the Partnership shall deposit with the Trustee or with a Paying Agent (or,
if the Partnership is acting as its own Paying Agent, which it may not do in the
case of a sinking fund payment under Article Twelve, segregate and hold in trust
as provided in Section 1003) an amount of money in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay on the
Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof which are to be redeemed on that date.

      SECTION 1106. Securities Payable on Redemption Date. Notice of redemption
having been given as aforesaid, the Securities so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein
specified in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) (together with accrued interest, if any, to the Redemption Date),
and from and after such date (unless the Partnership shall default in the
payment of the Redemption Price and accrued interest) such Securities shall, if
the same were interest-bearing, cease to


                                       68
<PAGE>   75
bear interest and the coupons for such interest appertaining to any Bearer
Securities so to be redeemed, except to the extent provided below, shall be
void. Upon surrender of any such Security for redemption in accordance with said
notice, together with all coupons, if any, appertaining thereto maturing after
the Redemption Date, such Security shall be paid by the Partnership at the
Redemption Price, together with accrued interest, if any, to the Redemption
Date; provided, however, that installments of interest on Bearer Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable
only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons for
such interest; and provided further that installments of interest on Registered
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Partnership and the Trustee if there be furnished
to them such security or indemnity as they may require to save each of them and
any Paying Agent harmless. If thereafter the Holder of such Security shall
surrender to the Trustee or any Paying Agent any such missing coupon in respect
of which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest represented by coupons shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons.

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

      SECTION 1107. Securities Redeemed in Part. Any Registered Security which
is to be redeemed only in part (pursuant to the provisions of this Article or of
Article Twelve) shall be surrendered at a Place of Payment therefor (with, if
the Partnership or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Partnership and the Trustee
duly executed by, the Holder thereof or his attorney duly authorized in writing)
and the Partnership shall execute and the Trustee shall authenticate and deliver
to the Holder of such Security without service charge a new Security or
Securities of the same series, of any authorized denomination as requested by
such Holder in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered. If a Global
Security is so surrendered, the Partnership shall execute and the Trustee shall
authenticate and deliver to the depositary, without service charge, a new Global


                                       69
<PAGE>   76
Security in a denomination equal to and in exchange for the unredeemed portion
of the principal of the Global Security so surrendered.


                         ARTICLE TWELVE - SINKING FUNDS

      SECTION 1201. Applicability of Article. The provisions of this Article
shall be applicable to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

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

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

      SECTION 1203. Redemption of Securities for Sinking Fund. Not less than 60
days prior to each sinking fund payment date for Securities of any series, the
Partnership will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing mandatory sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the


                                       70
<PAGE>   77
Trustee any Securities to be so delivered and credited. If such Officers'
Certificate shall specify an optional amount to be added in cash to the next
ensuing mandatory sinking fund payment, the Partnership shall thereupon be
obligated to pay the amount therein specified. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
1103 and cause notice of the redemption thereof to be given in the name of and
at the expense of the Partnership in the manner provided in Section 1104. Such
notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 1106 and 1107.


              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

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

      SECTION 1302. Repayment of Securities. Securities of any series subject to
repayment in whole or in part at the option of the Holders thereof will, unless
otherwise provided in the terms of such Securities, be repaid at a price equal
to the principal amount thereof, together with interest, if any, thereon accrued
to the Repayment Date specified in or pursuant to the terms of such Securities.
The Partnership covenants that on or prior to the Repayment Date it will deposit
with the Trustee or with a Paying Agent (or, if the Partnership is acting as its
own Paying Agent, segregate and hold in trust as provided in Section 1003) an
amount of money in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date.

      SECTION 1303. Exercise of Option. Securities of any series subject to
repayment at the option of the Holders thereof will contain an "Option to Elect
Repayment" form on the reverse of such Securities. In order for any Security to
be repaid at the option of the Holder, the Trustee must receive at the Place of
Payment therefor specified in the terms of such Security (or at such other place
or places of which the Partnership shall from time to time notify the Holders of
such Securities) not earlier than 60 days nor later than 30 days prior to the
Repayment Date (1) the Security so providing for such repayment together with
the "Option to Elect Repayment" form on the reverse thereof duly completed by
the Holder (or by the Holder's attorney duly authorized in writing) or (2) a
telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the National Association of Securities Dealers, Inc.
("NASD"), or a commercial bank or trust company in

the United States setting forth the name of the Holder of the Security, the
principal amount of the Security, the principal amount of the Security to be
repaid, the CUSIP number, if any, or a description of the tenor and terms of the
Security, a statement that the option to elect repayment is being exercised
thereby and a guarantee that the Security to be repaid, together with the duly
completed form entitled "Option to Elect Repayment" on the reverse of the
Security, will be received by the Trustee not later than the fifth Business Day
after the date of such telegram, telex, facsimile transmission or letter;
provided, however, that such telegram, telex, facsimile transmission or letter
shall only be effective if such Security and form duly completed are received by
the Trustee by such fifth Business Day. If less than the entire principal amount
of such Security is to be repaid in accordance with the terms of such Security,
the principal amount of such Security to be repaid, in increments of the minimum
denomination for Securities of such series, and the denomination or
denominations of the Security or Securities to be issued to the Holder for the
portion of the principal amount of such Security surrendered that is not to be
repaid, must be specified. The principal amount of any Security providing for
repayment at the option of the Holder thereof may not be repaid in part if,
following such repayment, the unpaid principal amount of such Security would be
less than the minimum authorized denomination of Securities of the series of
which such Security to be repaid is a part. Except as otherwise may be provided
by the terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Partnership.

      SECTION 1304. When Securities Presented for Repayment Become Due and
Payable. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Partnership on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Partnership shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Partnership, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable (but without interest thereon,
unless the Partnership shall default in the payment thereof) to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 307.


                                       72
<PAGE>   79
      If any Bearer Security surrendered for repayment shall not be accompanied
by all appurtenant coupons maturing after the Repayment Date, such Security may
be paid after deducting from the amount payable therefor as provided in Section
1302 an amount equal to the face amount of all such missing coupons, or the
surrender of such missing coupon or coupons may be waived by the Partnership and
the Trustee if there be furnished to them such security or indemnity as they may
require to save each of them and any Paying Agent harmless. If thereafter the
Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing coupon in respect of which a deduction shall have been made as
provided in the preceding sentence, such Holder shall be entitled to receive the
amount so deducted; provided, however, that interest represented by coupons
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of those
coupons.

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

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


              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

      SECTION 1401. Applicability of Article: Partnership's Option to Effect
Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections , as the case may be, together with the other provisions of this
Article (with such modifications thereto as may be specified pursuant to Section
301 with respect to any Securities), shall be applicable to such Securities and
any coupons appertaining thereto, and the Partnership may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.


                                       73
<PAGE>   80
      SECTION 1402. Defeasance and Discharge. Upon the Partnership's exercise of
the above option applicable to this Section with respect to any Securities of or
within a series, the Partnership shall be deemed to have been discharged from
its obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Partnership shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Partnership, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and
premium, if any) and interest, if any, on such Securities and any coupons
appertaining thereto when such payments are due, (B) the Partnership's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003 and with respect to the payment of Additional Amounts, if any, on such
Securities as contemplated by Section 1009, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article. Subject to
compliance with this Article Fourteen, the Partnership may exercise its option
under this Section notwithstanding the prior exercise of its option under
Section 1403 with respect to such Securities and any coupons appertaining
thereto.

      SECTION 1403. Covenant Defeasance. Upon the Partnership's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Partnership shall be released from its obligations under
Sections 1004 to 1007, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant, with respect to such Outstanding
Securities and any coupons appertaining thereto on and after the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Sections 1004 to 1007, inclusive, or such other
covenant, but shall continue to be deemed "Outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to such Outstanding Securities and any coupons appertaining thereto, the
Partnership may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such Section or such other
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such Section or such other covenant or by reason of reference in
any such Section or such other covenant to any other provision herein or in any
other document and such omission to comply shall not constitute a default or an
Event of Default under Section 501(4) or 501(8) or otherwise, as the case may
be, but, except as


                                       74
<PAGE>   81
specified above, the remainder of this Indenture and such Securities and any
coupons appertaining thereto shall be unaffected thereby.

      SECTION 1404. Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

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

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

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


                                       75
<PAGE>   82
            (d) In the case of an election under Section 1402, the Partnership
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Partnership has received from, or there has been published by, the Internal
Revenue Service a ruling, or (ii) since the date of execution of this Indenture,
there has been a change in the applicable Federal income tax law, in either case
to the effect that, and based thereon such opinion shall confirm that, the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such defeasance and will be subject to Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such defeasance had not occurred.

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

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

            (g) Notwithstanding any other provisions of this Section , such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Partnership in connection therewith pursuant to Section 301.

      SECTION 1405. Deposited Money and Government Obligations to Be Held in
Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Partnership acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and


                                       76
<PAGE>   83
premium, if any) and interest and Additional Amounts, if any, but such money
need not be segregated from other funds except to the extent required by law.

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

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

      Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Partnership from time to
time upon Partnership Request any money or Government Obligations (or other
property and any proceeds therefrom) held by it as provided in Section 1404
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect a defeasance or covenant defeasance, as applicable, in
accordance with this Article.

      SECTION 1501. Purposes for Which Meetings May Be Called. A meeting of
Holders of Securities of any series may be called at any time and from time to
time pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by

<PAGE>   84
      SECTION 1502. Call, Notice and Place of Meetings. (a) The Trustee may at
any time call a meeting of Holders of Securities of any series for any purpose
specified in Section 1501, to be held at such time and at such place as the
Trustee shall determine. Notice of every meeting of Holders of Securities of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided in Section 106, not less than 20 nor more than 180 days prior to
the date fixed for the meeting.

            (b) In case at any time the Partnership, pursuant to a Board
Resolution, or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1501, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 20 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Partnership or the Holders of Securities of such
series in the amount above specified, as the case may be, may determine the time
and the place for such meeting and may call such meeting for such purposes by
giving notice thereof as provided in subsection (a) of this Section.

      SECTION 1503. Persons Entitled to Vote at Meetings. To be entitled to vote
at any meeting of Holders of Securities of any series, a Person shall be (1) a
Holder of one or more Outstanding Securities of such series, or (2) a Person
appointed by an instrument in writing as proxy for a Holder or Holders of one or
more Outstanding Securities of such series by such Holder or Holders. The only
Persons who shall be entitled to be present or to speak at any meeting of
Holders of Securities of any series shall be the Persons entitled to vote at
such meeting and their counsel, any representatives of the Trustee and its
counsel and any representatives of the Partnership and its counsel.

      SECTION 1504. Quorum; Action. The Persons entitled to vote a majority in

that if any action is to be taken at such meeting with respect to a consent or
waiver which this Indenture expressly provides may be given by the Holders of
not less than a specified percentage in principal amount of the Outstanding
Securities of a series, the Persons entitled to vote such specified percentage
in principal amount of the Outstanding Securities of such series shall
constitute a quorum. In the absence of a quorum within 30 minutes after the time
appointed for any such meeting, the meeting shall, if convened at the request of
Holders of Securities of such series, be dissolved. In any other case the

adjourned meeting may be further adjourned for a period of not less than 10
days; at the reconvening of any meeting adjourned or further adjourned for lack
of a quorum, the persons entitled to vote 25% in aggregate principal amount of
the then Outstanding Securities shall constitute a


                                       78
<PAGE>   85
quorum for the taking of any action set forth in the notice of the original
meeting. Notice of the reconvening of any adjourned meeting shall be given as
provided in Section 1502(a), except that such notice need be given only once not
less than five days prior to the date on which the meeting is scheduled to be
reconvened.

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

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

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

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

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

      SECTION 1505. Determination of Voting Rights; Conduct and Adjournment of
Meetings. (a) Notwithstanding any provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and


                                       79
<PAGE>   86
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the Person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 104 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 104 or
other proof.

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

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

            (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

      SECTION 1506. Counting Votes and Recording Action of Meetings. The vote
upon any resolution submitted to any meeting of Holders of Securities of any
series shall be by written ballots on which shall be subscribed the signatures
of the Holders of Securities of such series or of their representatives by proxy
and the principal amounts and serial numbers of the Outstanding Securities of
such series held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record, at least in duplicate, of the proceedings
of each meeting of Holders of Securities of any Series shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the fact, setting forth a
copy of the notice of the meeting


                                       80
<PAGE>   87
and showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Partnership and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to

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 the

of such interest shall be legally enforceable), 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 (to the extent that the payment
of such interest shall be legally enforceable), which shall accrue from the date
of such demand for payment to the date payment of such interest has been made or

      Notice of redemption will be given by mail to Holders of Securities, not

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

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

      No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Partnership, which
is absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security at the times, places and rate, and in the coin or
currency, herein prescribed.

      As provided in the Indenture and subject to certain limitations therein
[and herein] set forth, the transfer of this Security is registrable in the
Security Register of the Partnership upon surrender of this Security for
registration of transfer at the office or agency of the Partnership in any place
where the principal of (and premium, if any) and interest on this Security are
payable, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Partnership and the Security Registrar duly executed
by, the Holder hereof or by his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

<PAGE>   97
      As provided in the Indenture and subject to certain limitations therein
[and herein] set forth, this Security is exchangeable for a like aggregate
principal amount of Securities of different authorized denominations but
otherwise having the same terms and conditions, as requested by the Holder
hereof surrendering the same.

      The Securities of this series are issuable only in registered form
[without coupons] in denominations of $_______ and any integral multiple
thereof.

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

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

      Notwithstanding anything contained herein to the contrary, no recourse
under or upon any obligation, covenant or agreement contained in this Security,
or because of any indebtedness evidenced hereby, or for any claim based hereon
or otherwise in respect hereof, shall be had for the payment of the principal of
or premium, if any, or the interest on this Security, or for any claim based
hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against (i) the Company or any
other past, present or future partner in the Partnership, (ii) against any other
Person which owns an interest, directly or indirectly, in any partner of the
Partnership or (iii) against any past, present or future stockholder, employee,
officer or director, as such, of the Company, or of any successor, either
directly or through the Partnership or the Company or any successor, whether by
virtue of any constitution, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.

      The Indenture and the Securities shall be governed by and construed in
accordance with the laws of [the State of New York] applicable to agreements
made and to be performed entirely in such State.

Officers' Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with
and an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (including certificates
delivered pursuant to Section 1008) shall include:

                  (1) a statement that each individual signing such certificate
         or opinion has read such condition or covenant 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 condition
         or covenant 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 103. 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 or opinion of an officer of the Company, as general
partner of the Partnership, may be based, insofar as it relates to legal
matters, upon an Opinion of Counsel, or a certificate or representations by
counsel, unless such officer knows, or in the exercise of reasonable care should
know, that the opinion, certificate or representations with respect to the
matters upon which his certificate or opinion is based are erroneous. Any such
Opinion of Counsel or certificate or representations 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 Company,

                                       11
<PAGE>   19
as general partner of the Partnership, stating that the information as to such
factual matters is in the possession of the Company, as general partner of the
Partnership, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 104. Acts of Holders. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of the Outstanding Securities of all series or one
or more series, as the case may be, may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Partnership. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Partnership and any agent of the Trustee or the Partnership, if
made in the manner provided in this Section. The record of any meeting of
Holders of Securities shall be proved in the manner provided in Section 1506.

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

                  (c) The ownership of Registered Securities shall be proved by
the Security

                                       12
<PAGE>   20
Register. As to any matter relating to beneficial ownership interests in any
Global Security, the appropriate depositary's records shall be dispositive for
purposes of this Indenture.

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

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

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

<PAGE>   21
         SECTION 105. Notices, etc., to Trustee and Partnership. Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

                           (1) the Trustee by any Holder or by the Partnership
         shall be sufficient for every purpose hereunder if made, given,
         furnished or filed in writing to or with the Trustee at
         ____________________; or

                           (2) the Partnership by the Trustee or by any Holder
         shall be sufficient for every purpose hereunder (unless otherwise
         herein expressly provided) if in writing and mailed, first class
         postage prepaid, to the Partnership, c/o the Company, addressed to it
         at the address of its principal office specified in the first paragraph
         of this Indenture or at any other address previously furnished in
         writing to the Trustee by the Partnership, Attention: Chief Financial
         Officer (with a copy to the Partnership's general counsel), or

                           (3) either the Trustee or the Partnership, by the
         other party, shall be sufficient for every purpose hereunder if given
         by facsimile transmission, receipt confirmed by telephone followed by
         an original copy delivered by guaranteed overnight courier; if to the
         Trustee at facsimile number (___) ________; and if to the Partnership
         at facsimile number (704) 334-4496.

         SECTION 106. Notice to Holders: Waiver. Where this Indenture provides
for notice of any event to Holders of Registered Securities by the Partnership
or the Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, if any, and not earlier than
the earliest date, if any, prescribed for the giving of such notice. In any case
where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

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

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given if published in an

                                       14
<PAGE>   22
Authorized Newspaper in The City of New York and in such other city or cities as
may be specified in such Securities on a Business Day, such publication to be
not later than the latest date, if any, and not earlier than the earliest date,
if any, prescribed for the giving of such notice. Any such notice shall be
deemed to have been given on the date of such publication or, if published more
than once, on the date of the first such publication.

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

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

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

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

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

         SECTION 109. Severability Clause. In case any provision in this
Indenture or in any Security or coupon shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

         SECTION 110. Benefits of Indenture. Nothing in this Indenture or in the
Securities or coupons, express or implied, shall give to any Person, other than
the parties hereto, any

                                       15
<PAGE>   23
Security Registrar, any Paying Agent, any Authenticating Agent and their
successors hereunder and the Holders any benefit or any legal or equitable
right, remedy or claim under this Indenture.

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

         SECTION 112. Legal Holidays. In any case where any Interest Payment
Date, Redemption Date, Repayment Date, sinking fund payment date, Stated
Maturity or Maturity of any Security or the last date on which a Holder has the
right to exchange a Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or any
Security or coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu hereof), payment of
interest or any Additional Amounts or principal (and premium, if any) or
exchange of such security need not be made at such Place of Payment on such
date, but (except as otherwise provided in the supplemental indenture with
respect to such Security) may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date, Redemption Date, Repayment Date or sinking fund payment date, or
at the Stated Maturity or Maturity, or on such last day for exchange, provided
that no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be.

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

         SECTION 114. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with another provision hereof which is required
or deemed to be included

                                       16
<PAGE>   24
in this Indenture by any of the provisions of the Trust Indenture Act, such
required provision shall control. If any provision of this Indenture modifies or
excludes any provision of the Trust Indenture Act that may be so modified or
excluded, the latter provision shall be deemed to apply to this Indenture as so
modified or to be excluded, as the case may be.


                         ARTICLE TWO - SECURITIES FORMS

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

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

         The definitive Securities and coupons shall be printed, lithographed or
engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or mechanically reproduced on safety paper or
may be produced in any other manner, all as determined by the officers executing
such Securities or coupons, as evidenced by their execution of such Securities
or coupons.

         SECTION 202. Form of Trustee's Certificate of Authentication. Subject
to Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

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

                                                 [NAME OF TRUSTEE]
                                                   as Trustee


                                                 By___________________________
                                                      Authorized Signatory

                                       17
<PAGE>   25
         SECTION 203. Securities Issuable in Global Form. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders thereof, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner or by such Person or Persons as shall be
specified therein or in the Partnership Order to be delivered to the Trustee
pursuant to Section 303 or 304. Subject to the provisions of Section 303 and, if
applicable, Section 304, the Trustee shall deliver and redeliver any Global
Security in permanent global form in the manner and upon instructions given by
the Person or Persons specified therein or in the applicable Partnership Order.
If a Partnership Order pursuant to Section 303 or 304 has been, or
simultaneously is, delivered, any instructions by the Partnership with respect
to endorsement or delivery or redelivery of a Global Security shall be in
writing but need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Partnership and the Partnership delivers to the Trustee the Global
Security together with written instructions (which need not comply with Section
102 and need not be accompanied by an Opinion of Counsel) with regard to the
reduction in the principal amount of Securities represented thereby, together
with the written statement contemplated by the last sentence of Section 303.

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

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

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

                  "This Security is a Global Security within the meaning set
                  forth in the Indenture hereinafter referred to and is
                  registered in the

                                       18
<PAGE>   26
                  name of a Depositary or a nominee of a Depositary. This
                  Security is exchangeable for Securities registered in the name
                  of a person other than the Depositary or its nominee only in
                  the limited circumstances described in the Indenture, and may
                  not be transferred except as a whole by the Depositary to a
                  nominee of the Depositary or by a nominee of the Depositary to
                  the Depositary or another nominee of the Depositary or by the
                  Depositary or its nominee to a successor Depositary or its
                  nominee."


                         ARTICLE THREE - THE SECURITIES

         SECTION 301. Amount Unlimited; Issuable in Series. The aggregate
principal amount of Securities which may be authenticated and delivered under
this Indenture is unlimited.

         The Securities may be issued in one or more series. There shall be
established in one or more Board Resolutions or pursuant to authority granted by
one or more Board Resolutions and, subject to Section 303, set forth in an

hereto, prior to the issuance of Securities of any series:

                           (1) the title of the Securities of the series (which
         shall distinguish the Securities of such series from all other series
         of Securities);

                           (2) any limit upon the aggregate principal amount of
         the Securities of the series that may be authenticated and delivered
         under this Indenture (except for Securities authenticated and delivered
         upon registration of transfer of, or in exchange for, or in lieu of,
         other Securities of the series pursuant to Section 304, 305, 306, 906,
         1107 or 1305);

                           (3) the date or dates, or the method by which such
         date or dates will be determined, on which the principal of the
         Securities of the series shall be payable;

                           (4) the rate or rates at which the Securities of the
         series shall bear interest, if any, or the method by which such rate or
         rates shall be determined, the date or dates from which such interest
         shall accrue or the method by which such date or dates shall be
         determined, the Interest Payment Dates on which such interest will be
         payable and the Regular Record Date, if any, for the interest payable
         on any Registered Security on any Interest Payment Date, or the method
         by which such date shall be determined, and the basis upon which
         interest shall be calculated if other than that of a 360-day year of
         twelve 30-day months;

                           (5) the place or places where the principal of (and

         respect of, Securities of the series shall be payable, any Registered
         Securities of the series may be surrendered for registration of
         transfer or exchange and notices or demands to or upon the Partnership
         in respect of the Securities of the series and this Indenture may be
         served;

                           (6) the period or periods within which, the price or
         prices at which, the currency or currencies, currency unit or units or
         composite currency or currencies in which, and other terms and

         whole or in part, at the option of the Partnership, if the Partnership
         is to have the option;

                           (7) the obligation, if any, of the Partnership to

         sinking fund or analogous provision or at the option of a Holder
         thereof, and the period or periods within which or the date or dates on
         which, the price or prices at which, the currency or currencies,
         currency unit or units or composite currency or currencies in which,
         and other terms and conditions upon which Securities of the series
         shall be redeemed, repaid or purchased, in whole or in part, pursuant
         to such obligation;

                           (8) if other than denominations of $1,000 and any
         integral multiple thereof, the denominations in which any Securities of
         the series shall be issuable;

         portion of the principal amount of Securities of the series that shall
         be payable upon declaration of acceleration of the Maturity thereof

         determined;

         Currencies in which payment of the principal of (and premium, if any)
         and interest or Additional Amounts, if any, on the Securities of the

         be denominated and the manner of determining the equivalent thereof in
         Dollars for purposes of the definition of "Outstanding" in Section 101;

                           (12) whether the amount of payments of principal of
         (and premium, if any) or interest, if any, on the Securities of the
         series may be determined with reference to an index, formula or other
         method (which index, formula or method may be based, without
         limitation, on one or more currencies, currency units, composite
         currencies, commodities, equity indices or other indices), and the
         manner in which such amounts shall be determined;

<PAGE>   28
                           (13) whether the principal of (and premium, if any)
         or interest or Additional Amounts, if any, on the Securities of the
         series are to be payable, at the election of the Partnership or a
         Holder thereof, in a currency or currencies, currency unit or units or
         composite currency or currencies other than that in which such
         Securities are denominated or stated to be payable, the period or
         periods within which, and the terms and conditions upon which, such
         election may be made, and the time and manner of, and identity of the
         exchange rate agent with responsibility for, determining the exchange
         rate between the currency or currencies, currency unit or units or
         composite currency or currencies in which such Securities are
         denominated or stated to be payable and the currency or currencies,
         currency unit or units or composite currency or currencies in which
         such Securities are to be so payable;

         the Holders of Securities of the series upon the occurrence of such
         events as may be specified;

         additions to the Events of Default or covenants of the Partnership with

         covenants set forth herein;

         delivery of Bearer Securities and the terms upon which Bearer
         Securities of the series may be exchanged for Registered Securities of
         the series and vice versa (if permitted by applicable laws and
         regulations), whether any Securities of the series are to be issuable
         initially in temporary global form and whether any Securities of the
         series are to be issuable in permanent global form with or without
         coupons and, if so, whether beneficial owners of interests in any such
         permanent global Security may exchange such interests for Securities of
         such series and of like tenor of any authorized form and denomination
         and the circumstances under which any such exchanges may occur, if
         other than in the manner provided in Section 305, and, if Registered
         Securities of the series are to be issuable as a Global Security, the
         identity of the depositary for such series;

                           (17) the date as of which any Bearer Securities of
         the series and any temporary Global Security representing Outstanding
         Securities of the series shall be dated if other than the date of
         original issuance of the first Security of the series to be issued;

                           (18) the Person to whom any interest on any
         Registered Security of the series shall be payable, if other than the

         Record Date for such interest, the manner in which, or the Person to

                                       21
<PAGE>   29
         interest on any Bearer Security of the series shall be payable, if
         otherwise than upon presentation and surrender of the coupons
         appertaining thereto as they severally mature, and the extent to which,
         or the manner in which, any interest payable on a temporary Global
         Security on an Interest Payment Date will be paid if other than in the
         manner provided in Section 304;

                           (19) the applicability, if any, of Sections 1402
         and/or 1403 to the Securities of the series and any provisions in
         modification of, in addition to or in lieu of any of the provisions of
         Article Fourteen;

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

                           (21) if the Securities of the series are to be issued
         upon the exercise of warrants, the time, manner and place for such
         Securities to be authenticated and delivered;

                           (22) whether and under what circumstances the
         Partnership will pay Additional Amounts as contemplated by Section 1009
         on the Securities of the series to any Holder who is not a United
         States person (including any modification to the definition of such
         term) in respect of any tax, assessment or governmental charge and, if
         so, whether the Partnership will have the option to redeem such
         Securities rather than pay such Additional Amounts (and the terms of
         any such option); and

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

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

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

                                       22
<PAGE>   30
         SECTION 302. Denominations. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions with respect to the Securities of any series, the
Securities of such series, other than Global Securities (which may be of any
denomination), shall be issuable in denominations of $1,000 and any integral
multiple thereof.

         SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Partnership by the Chairman of the Board, and the President or one of the
Vice Presidents of the Company, as general partner of the Partnership, under its
corporate seal reproduced thereon, and attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
and coupons may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Securities.

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

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

                                       23
<PAGE>   31
         If all the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Partnership Order may set forth procedures acceptable to
the Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to TIA Section 315(a) through 315(d)) shall be
fully protected in relying upon,

                  (i)      an Opinion of Counsel stating that

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

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

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

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

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

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

                                       24
<PAGE>   32
paragraph at the time of issuance of each Security of such series, but such
order, opinion and certificates, with appropriate modifications to cover such
future issuances, shall be delivered at or before the time of issuance of the
first Security of such series.

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

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global Security) shall have been authenticated and delivered
hereunder but never issued and sold by the Partnership, and the Partnership
shall deliver such Security to the Trustee for cancellation as provided in
Section 309 together with a written statement (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Partnership, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

         SECTION 304. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Partnership may execute, and upon
Partnership Order the Trustee shall authenticate and deliver, temporary
Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form, or, if authorized, in bearer form with one or more coupons or without
coupons, and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. In the case of
Securities of any series, such temporary Securities may be in global form.

         Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution), if temporary Securities of any series are issued, the
Partnership will cause definitive Securities of that series to be prepared
without unreasonable delay. After the preparation of definitive Securities of
such series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Partnership in a Place of Payment
for that series, without charge to the Holder. Upon surrender for cancellation
of any one or more temporary Securities of any series (accompanied by any
non-matured coupons appertaining thereto), the Partnership shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal

                                       25
<PAGE>   33
amount of definitive Securities of the same series of authorized denominations;
provided, however, that no definitive Bearer Security shall be delivered in
exchange for a temporary Registered Security; and provided further that a
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303. Until
so exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

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

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

         Unless otherwise specified in such temporary Global Security, the
interest of a

                                       26
<PAGE>   34
beneficial owner of Securities of a series in a temporary Global Security shall
be exchanged for definitive Securities of the same series and of like tenor
following the Exchange Date when the account holder instructs Euroclear or
CEDEL, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or CEDEL, as the case may be, a certificate in the form set forth
in Exhibit B-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary Global
Security shall be delivered only outside the United States.

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

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

         Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Partnership in a Place of Payment for that series, the
Partnership shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Registered
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount, bearing a number not contemporaneously outstanding,
and containing identical terms and provisions.

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

         If (but only if) permitted by the applicable Board Resolution and
(subject to Section 303) set forth in the applicable Officers' Certificate, or
in any indenture supplemental hereto, delivered as contemplated by Section 301,
at the option of the Holder, Bearer Securities of any series may be exchanged
for Registered Securities of the same series of any authorized denominations and
of a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Partnership in an amount equal to the face amount of such missing coupon
or coupons, or the surrender of such missing coupon or

                                       28
<PAGE>   36
coupons may be waived by the Partnership and the Trustee if there is furnished
to them such security or indemnity as they may require to save each of them and
any Paying Agent harmless. If thereafter the Holder of such Security shall
surrender to any Paying Agent any such missing coupon in respect of which such a
payment shall have been made, such Holder shall be entitled to receive the
amount of such payment; provided, however, that, except as otherwise provided in
Section 1002, interest represented by coupons shall be payable only upon
presentation and surrender of those coupons at an office or agency located
outside the United States. Notwithstanding the foregoing, in case a Bearer
Security of any series is surrendered at any such office or agency in a
permitted exchange for a Registered Security of the same series and like tenor
after the close of business at such office or agency on (i) any Regular Record
Date and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the related proposed date for payment of
Defaulted Interest, such Bearer Security shall be surrendered without the coupon
relating to such Interest Payment Date or proposed date for payment, as the case
may be, and interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the Holder of such coupon when due in
accordance with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Partnership shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security shall be exchangeable
only as provided in this paragraph. If the depositary for any permanent Global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
Global Security expressly permit such Global Security to be exchanged in whole
or in part for definitive Securities, a Global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such Global Security selected or approved by the
Partnership or to a nominee of such successor to DTC. If at any time DTC
notifies the Partnership that it is unwilling or unable to continue as
depositary for the applicable Global Security or Securities or if at any time
DTC ceases to be a clearing agency registered under the Securities Exchange Act
of 1934 if so required by applicable law or regulation, the Partnership shall
appoint a successor depositary with respect to such Global Security or
Securities. If (x) a successor depositary for such Global Security or Securities
is not appointed by the Partnership within 90 days after the Partnership
receives such notice or becomes aware of such unwillingness, inability or
ineligibility, (y) an Event of Default has occurred and is continuing and the
beneficial owners representing a majority in principal amount of the applicable
series of Securities represented by such Global Security or Securities advise
DTC to cease acting as depositary for such Global Security or Securities or (z)
the Partnership, in its sole discretion, determines at any time that all
Outstanding Securities (but not less than all) of any series issued or issuable
in the form of one or more Global Securities shall no longer be represented by
such Global Security or Securities, then the Partnership shall execute, and the

                                       29
<PAGE>   37
Trustee shall authenticate and deliver definitive Securities of like series,
rank, tenor and terms in definitive form in an aggregate principal amount equal
to the principal amount of such Global Security or Securities. If any beneficial
owner of an interest in a permanent global Security is otherwise entitled to
exchange such interest for Securities of such series and of like tenor and
principal amount of another authorized form and denomination, as specified as
contemplated by Section 301 and provided that any applicable notice provided in
the permanent Global Security shall have been given, then without unnecessary
delay but in any event not later than the earliest date on which such interest
may be so exchanged, the Partnership shall execute, and the Trustee shall
authenticate and deliver definitive Securities in aggregate principal amount
equal to the principal amount of such beneficial owner's interest in such
permanent Global Security. On or after the earliest date on which such interests
may be so exchanged, such permanent Global Security shall be surrendered for
exchange by DTC or such other depositary as shall be specified in the
Partnership Order with respect thereto to the Trustee, as the Partnership's
agent for such purpose; provided, however, that no such exchanges may occur
during a period beginning at the opening of business 15 days before any
selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those selected
for redemption; and provided further that no Bearer Security delivered in
exchange for a portion of a permanent Global Security shall be mailed or
otherwise delivered to any location in the United States. If a Registered
Security is issued in exchange for any portion of a permanent Global Security
after the close of business at the office or agency where such exchange occurs
on (i) any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent Global Security is payable in accordance with the provisions
of this Indenture.

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

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

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Partnership may require payment of a sum
sufficient to cover any tax or

                                       30
<PAGE>   38
other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Securities, other than exchanges
pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

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

         SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Partnership, together with, in proper cases,
such security or indemnity as may be required by the Partnership or the Trustee
to save each of them or any agent of either of them harmless, the Partnership
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and principal amount, containing
identical terms and provisions and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
the surrendered Security.

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


                                       31
<PAGE>   39
         Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Partnership in its discretion may,
instead of issuing a new Security, with coupons corresponding to the coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium, if any),
any interest on and any Additional Amounts with respect to, Bearer Securities
shall, except as otherwise provided in Section 1002, be payable only at an
office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 301, any interest on Bearer Securities
shall be payable only upon presentation and surrender of the coupons
appertaining thereto.

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

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Partnership, whether or not the destroyed, lost or stolen Security and its
coupons, if any, or the destroyed, lost or stolen coupon shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, duly issued hereunder.

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

         SECTION 307. Payment of Interest; Interest Rights Preserved. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that is
payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Partnership
maintained for such purpose pursuant to Section 1002; provided, however, that
each installment of interest on any Registered Security may at the Partnership's
option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 308, to the
address of such Person as it appears on the Security Register or (ii) transfer
to an account maintained by the payee located inside the United States.

         Unless otherwise provided as contemplated by Section 301 with respect
to the

                                       32
<PAGE>   40
Securities of any series, payment of interest may be made, in the case of a
Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

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

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

         Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Partnership, at its election in each case,
as provided in clause (1) or (2) below:

                           (1) The Partnership may elect to make payment of any
         Defaulted Interest to the Persons in whose names the Registered
         Securities of such series (or their respective Predecessor Securities)
         are registered at the close of business on a Special Record Date for
         the payment of such Defaulted Interest, which shall be fixed in the
         following manner. The Partnership shall notify the Trustee in writing
         of the amount of Defaulted Interest proposed to be paid on each
         Registered Security of such series and the date of the proposed payment
         (which shall not be less than 20 days after such notice is received by
         the Trustee), and at the same time the Partnership shall deposit with
         the Trustee an amount of money in the currency or currencies, currency
         unit or units or composite currency or currencies in which the
         Securities of such series are payable (except as otherwise specified
         pursuant to Section 301 for the Securities of such series) equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit on or 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

                                       33
<PAGE>   41
         Defaulted Interest which shall be not more than 15 days and not less
         than 10 days prior to the date of the proposed payment and not less
         than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Partnership of
         such Special Record Date and, in the name and at the expense of the
         Partnership, shall cause notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor to be mailed,
         first-class postage prepaid, to each Holder of Registered Securities of
         such series at his address as it appears in the Security Register not
         less than 10 days prior to such Special Record Date. The Trustee may,
         in its discretion, in the name and at the expense of the Partnership,
         cause a similar notice to be published at least once in an Authorized
         Newspaper in each Place of Payment, but such publications shall not be
         a condition precedent to the establishment of such Special Record Date.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been mailed as aforesaid, such
         Defaulted Interest shall be paid to the Persons in whose names the
         Registered Securities of such series (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         clause (2). In case a Bearer Security of any series is surrendered at
         the office or agency in a Place of Payment for such series in exchange
         for a Registered Security of such series after the close of business at
         such office or agency on any Special Record Date and before the opening
         of business at such office or agency on the related proposed date for
         payment of Defaulted Interest, such Bearer Security shall be
         surrendered without the coupon relating to such proposed date of
         payment and Defaulted Interest will not be payable on such proposed
         date of payment in respect of the Registered Security issued in
         exchange for such Bearer Security, but will be payable only to the
         Holder of such coupon when due in accordance with the provisions of
         this Indenture.

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

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

         SECTION 308. Persons Deemed Owners. Prior to due presentment of a
Registered Security for registration of transfer, the Partnership, the Trustee
and any agent of the Partnership or the Trustee may treat the Person in whose
name such Registered Security is registered as the owner of such Security for
the purpose of receiving payment of principal of

                                       34
<PAGE>   42
(and premium, if any), and (subject to Sections 305 and 307) interest on, such
Registered Security and for all other purposes whatsoever, whether or not such
Registered Security be overdue, and neither the Partnership, the Trustee nor any
agent of the Partnership or the Trustee shall be affected by notice to the
contrary. All such payments so made to any such Person, or upon such Person's
order, shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for money payable upon any such Security.

         Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Partnership, the Trustee and any agent of the Partnership
or the Trustee may treat the Holder of any Bearer Security and the Holder of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and neither the
Partnership, the Trustee nor any agent of the Partnership or the Trustee shall
be affected by notice to the contrary.

         No Holder of any beneficial interest in any Global Security held on its
behalf by a depositary shall have any rights under this Indenture with respect
to such Global Security and such depositary shall be treated by the Partnership,
the Trustee, and any agent of the Partnership or the Trustee as the owner of
such Global Security for all purposes whatsoever. None of the Partnership, the
Trustee, any Paying Agent or the Security Registrar will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

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

         SECTION 309. Cancellation. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose shall be promptly 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
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. If the Partnership shall so acquire any of the Securities, however,
such

                                       35
<PAGE>   43
acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section , except as expressly permitted by this Indenture. Cancelled
Securities and coupons held by the Trustee shall be destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Partnership,
unless the Trustee is otherwise directed by a Partnership Order.

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


                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

         SECTION 401. Satisfaction and Discharge of Indenture. This Indenture
shall upon Partnership Request cease to be of further effect with respect to any
series of Securities specified in such Partnership Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for and any right to receive Additional
Amounts, as provided in Section 1009), and the Trustee, upon receipt of a
Partnership Order, and at the expense of the Partnership, shall execute
instruments in form and substance satisfactory to the Trustee and the
Partnership acknowledging satisfaction and discharge of this Indenture as to
such series when

                           (1)      either

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

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

                                       36

                  cancellation

                                    (i) have become due and payable, or

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

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

                  and the Partnership, in the case of (i), (ii) or (iii) above,
                  has irrevocably deposited or caused to be deposited with the
                  Trustee as trust funds in trust for the purpose an amount in
                  the currency or currencies, currency unit or units or

                  such series are payable, sufficient to pay and discharge the
                  entire indebtedness on such Securities and such coupons not
                  theretofore delivered to the Trustee for cancellation, for

                  Additional Amounts with respect thereto, 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

                                       37
<PAGE>   45
the Persons entitled thereto, of the principal (and premium, if any), and any
interest and Additional Amounts for whose payment such money has been deposited
with or received by the Trustee, but such money need not be segregated from
other funds except to the extent required by law.

         SECTION 501. Events of Default. "Event of Default," wherever used

         series or of any coupon appertaining thereto, when such interest,
         Additional Amounts or coupon becomes due and payable, and continuance
         of such default for a period of 30 days; or

                           (2) default in the payment of the principal of (or

         covenant or warranty of the Partnership in this Indenture with respect
         to any Security of that series (other than a covenant or warranty a
         default in whose performance or whose breach is elsewhere in this
         Section specifically dealt with), and continuance of such default or
         breach for a period of 60 days after there has been given, by
         registered or certified mail, to the Partnership by the Trustee or to
         the Partnership and the Trustee by the Holders of at least 25% in
         principal amount of the Outstanding Securities of that series a written

         remedied and stating that such notice is a "Notice of Default"
         hereunder; or

                           (5) default under any bond, debenture, note or other
         evidence of indebtedness for money borrowed (except mortgage

         aggregate principal amount in excess of $25,000,000 or under any
         indenture or instrument under which there may be issued or by which
         there may be secured or evidenced any indebtedness for money borrowed
         (except mortgage indebtedness) by the Partnership or any of its
         Subsidiaries in an aggregate principal amount in excess of $25,000,000,
         whether such indebtedness exists on the date of such Indenture or shall
         thereafter be created, which default shall have resulted in such

                                       38
<PAGE>   46
         indebtedness becoming or being declared due and payable prior to the
         date on which it would otherwise have become due and payable or such
         obligations being accelerated, without such acceleration having been
         rescinded or annulled; or

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

                                    (A) commences a voluntary case,

                                    (B) consents to the entry of an order for
                  relief against it in an involuntary case,

                                    (C) consents to the appointment of a
                  Custodian of it or for all or substantially all of its
                  property, or

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

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

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

                                    (B) appoints a Custodian of the Partnership

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

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

         SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if Securities of
that Series are Original Issue Discount Securities or Indexed Securities,

                                       39
<PAGE>   47
such portion of the principal as may be specified in the terms thereof) of all
the Securities of that series to be due and payable immediately, by a notice in
writing to the Partnership (and to the Trustee if given by the Holders), and
upon any such declaration such principal or specified portion thereof shall
become immediately due and payable.

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

                           (1) the Partnership has paid or deposited with the
         Trustee a sum sufficient to pay in the currency, currency unit or
         composite currency in which the Securities of such series are payable
         (except as otherwise specified pursuant to Section 301 for the
         Securities of such series):

                                    (A) all overdue installments of interest on
                  and any Additional Amounts payable in respect of all
                  Outstanding Securities of that series and any related coupons,

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

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

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

                           (2) all Events of Default with respect to Securities
         of that series, other than the nonpayment of the principal of (or
         premium, if any) or interest on Securities of that series which have
         become due solely by such declaration of acceleration, have been cured
         or waived as provided in Section 513.

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

         SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee. The Partnership covenants that if:

                                       40
<PAGE>   48
                           (1) default is made in the payment of any installment
         of interest or Additional Amounts, if any, on any Security of any
         series and any related coupon when such interest or Additional Amount
         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 of any series at its Maturity,

then the Partnership will, upon demand of the Trustee, pay to the Trustee, for
the benefit of the Holders of such Securities of such series and coupons, the
whole amount then due and payable on such Securities and coupons for principal
(and premium, if any) and interest and Additional Amounts, with interest upon
any overdue principal (and premium, if any) and, to the extent that payment of
such interest shall be legally enforceable, upon any overdue installments of
interest or Additional Amounts, if any, at the rate or rates borne by or
provided for in such Securities, and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

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

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

         SECTION 504. Trustee May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Partnership or any other obligor upon the Securities or the property of the
Partnership or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities of any series shall
then be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the
Partnership for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise:


                                       41
<PAGE>   49
                                    (i) to file and prove a claim for the whole
         amount, or such lesser amount as may be provided for in the Securities
         of such series, of principal (and premium, if any) and interest and
         Additional Amounts, if any, owing and unpaid in respect of the
         Securities and to file such other papers or documents as may be
         necessary or advisable in order to have the claims of the Trustee
         (including any claim for the reasonable compensation, expenses,
         disbursements and advances of the Trustee, its agents and counsel) and
         of the Holders allowed in such judicial proceeding, and

                                    (ii) to collect and receive any moneys or
         other property payable or deliverable on any such claims and to
         distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series and coupons to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

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

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

         SECTION 505. Trustee May Enforce Claims Without Possession of
Securities or Coupons. All rights of action and claims under this Indenture or
any of the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or coupons or the production
thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, be for the ratable benefit of the Holders of the
Securities and coupons in respect of which such judgment has been recovered.

         SECTION 506. Application of Money Collected. Any money collected by the
Trustee pursuant to this Article shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium, if

                                       42
<PAGE>   50
any) or interest and any Additional Amounts, upon presentation of the Securities
or coupons, or both, as the case may be, and the notation thereon of the payment
if only partially paid and upon surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee and any
         predecessor Trustee under Section 606;

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

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

         SECTION 507. Limitation on Suits. No Holder of any Security of any
series or any related coupon shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless:

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

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain

                                       43
<PAGE>   51
priority or preference over any other of such Holders or to enforce any right
under this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all such Holders.

         SECTION 508. Unconditional Right of Holders to Receive Principal,
Premium, if any, Interest and Additional Amounts. Notwithstanding any other
provision in this Indenture, but subject to the provisions of Article Sixteen,
the Holder of any Security or coupon shall have the right which is absolute and
unconditional to receive payment of the principal of (and premium, if any) and
(subject to Sections 305 and 307) interest on, and any Additional Amounts in
respect of, such Security or payment of such coupon on the respective due dates
expressed in such Security or coupon (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

         SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Partnership, the Trustee and
the Holders of Securities and coupons shall, subject to any determination in
such proceeding, be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

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

         SECTION 511. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of any Security or coupon to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or coupons, as the
case may be.

         SECTION 512. Control by Holders of Securities. The Holders of not less
than a majority in principal amount of the Outstanding Securities of any series
shall have the right to

                                       44
<PAGE>   52
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee with respect to the Securities of such series, provided that

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

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

                           (3) the Trustee need not take any action which might
         involve it in personal liability or be unduly prejudicial to the
         Holders of Securities of such series not joining therein.

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

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

                           (1) in the payment of the principal of (or premium,
         if any) or interest on or Additional Amounts payable in respect of any
         Security of such series or any related coupons, or

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

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

         SECTION 514. Waiver of Usury, Stay or Extension Laws. The Partnership
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Partnership (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will

                                       45
<PAGE>   53
suffer and permit the execution of every such power as though no such law had
been enacted.

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


                            ARTICLE SIX - THE TRUSTEE

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

         SECTION 602. Certain Rights of Trustee. Subject to the provisions of
TIA Section 315(a) through 315(d):

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

                                       46
<PAGE>   54
         proper party or parties;

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

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

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

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

                           (6) the Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, coupon or other paper
         or document, unless requested in writing so to do by the Holders of not
         less than a majority in aggregate principal amount of the Outstanding
         Securities of any series; provided that, if the payment within a
         reasonable time to the Trustee of the costs, expenses or liabilities
         likely to be incurred by it in the making of such investigation is, in
         the opinion of the Trustee, not reasonably assured to the Trustee by
         the security afforded to it by the terms of this Indenture, the Trustee
         may require reasonable indemnity against such expenses or liabilities
         as a condition to proceeding; the reasonable expenses of every such
         examination shall be paid by the Holders or, if paid by the Trustee,
         shall be repaid by the Holders upon demand. The Trustee, in its
         discretion, may make such further inquiry or investigation into such
         facts or matters as it may see fit, and, if the Trustee shall determine
         to make such further inquiry or investigation, it shall be entitled to
         examine the books, records and premises of the Partnership and the
         Company, as applicable, relevant to the facts or matters that are the

                                       47
<PAGE>   55
         subject of its inquiry, personally or by agent or attorney;

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

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

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

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

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

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

         SECTION 605. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Partnership.


                                       48
<PAGE>   56
         SECTION 606.  Compensation and Reimbursement.  The Partnership agrees:

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

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

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

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

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

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

         SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
Federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and

                                       49
<PAGE>   57
with the effect hereinafter specified in this Article. Neither the Partnership
nor any Person directly or indirectly controlling, controlled by, or under
common control with the Partnership shall serve as Trustee.

         SECTION 608.  Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 609.

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

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

                  (d) If at any time:

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

                           (2) the Trustee shall cease to be eligible under
         Section 607 and shall fail to resign after written request therefor by
         the Partnership or by any Holder of a Security who has been a bona fide
         Holder of a Security for at least six months, or

                           (3) the Trustee shall become incapable of acting or
         shall be adjudged a bankrupt or insolvent or a receiver of the Trustee
         or of its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Partnership by or pursuant to a Board Resolution
may remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.


                                       50
<PAGE>   58
                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause with respect to the Securities of one or more series, the Partnership,
by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee
or Trustees with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
be only one Trustee with respect to the Securities of any particular series).
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to the Securities
of any series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered to the
Partnership and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Partnership. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Partnership or the Holders of Securities and accepted appointment in the manner
hereinafter provided, any Holder of a Security who has been a bona fide Holder
of a Security of such series for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the appointment of a successor Trustee with respect to Securities of such
series.

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

         SECTION 609. Acceptance of Appointment by Successor. (a) In case of the
appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Partnership and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Partnership or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee, and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder, subject nevertheless to its claim, if any,
provided for in Section 606.

                  (b) In case of the appointment hereunder of a successor
Trustee with respect to the Securities of one or more (but not all) series, the
Partnership, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and

                                       51
<PAGE>   59
deliver an indenture supplemental hereto, pursuant to Article Nine hereof,
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Partnership or any successor Trustee,
such retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

                  (c) Upon request of any such successor Trustee, the
Partnership shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts referred to in paragraph (a) or (b) of this Section 609, as the case may
be.

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

         SECTION 610. Merger, Conversion, Consolidation or Succession to
Business. Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities or coupons shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities or coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such

                                       52
<PAGE>   60
Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

         SECTION 611. Appointment of Authenticating Agent. At any time when any
of the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption or
repayment thereof, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the
Partnership. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Partnership and shall at
all times be a bank or trust company or corporation organized and doing business
and in good standing under the laws of the United States of America or of any
state or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or state
authorities. If such Authenticating Agent publishes reports of condition at
least annually, pursuant to law or the requirements of the aforesaid supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. In case at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

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

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Partnership. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent

                                       53
<PAGE>   61
by giving written notice of termination to such Authenticating Agent and to the
Partnership. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee for
such series may appoint a successor Authenticating Agent which shall be
acceptable to the Partnership and shall give notice of such appointment to all
Holders of Securities of the series with respect to which such Authenticating
Agent will serve in the manner set forth in Section 106. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent herein. No
successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

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

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

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

                  (b) at such other times as the Trustee may request in writing,

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

         SECTION 801. Consolidations and Mergers of Partnership and Sales,
Leases and Conveyances Permitted Subject to Certain Conditions. The Partnership
may consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into, any other entity, provided that in any such
case, (1) either the Partnership shall be the continuing entity, or the
successor entity (if other than the Partnership) formed by or resulting from any
such consolidation or merger or which shall have received the transfer of such
assets, shall expressly assume the due and punctual payment of the principal of
(and premium, if any) and any interest (including all Additional Amounts, if
any, payable pursuant to Section 1009) on all of the Securities, according to
their tenor, and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by the Partnership by
supplemental indenture, complying with Article Nine hereof, satisfactory to the
Trustee, executed and delivered to the Trustee by such entity and (2)
immediately after giving effect to such transaction and treating any
indebtedness which becomes an obligation of the Partnership or any Subsidiary as
a result thereof as having been incurred by the Partnership or such Subsidiary
at the time of such transaction, no Event of Default, and no event which, after
notice or the lapse of time, or both, would become an Event of Default, shall
have occurred and be continuing.

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

                                       56
<PAGE>   64
prescribed, the Trustee shall authenticate and shall deliver any Securities
which previously shall have been signed and delivered by the Partnership to the
Trustee for authentication, and any Securities which such successor entity
thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Securities so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Securities theretofore or
thereafter issued in accordance with the terms of this Indenture as though all
of such Securities had been issued at the date of the execution hereof.

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

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


                     ARTICLE NINE - SUPPLEMENTAL INDENTURES

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

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

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

                           (3) to add any additional Events of Default for the
         benefit of the Holders of all or any series of Securities (and if such
         Events of Default are to be for the benefit of less than all series of
         Securities, stating that such Events of Default are expressly being
         included solely for the benefit of such series); provided, however,
         that in respect of any such additional Events of Default such
         supplemental indenture may

                                       57
<PAGE>   65
         provide for a particular period of grace after default (which period
         may be shorter or longer than that allowed in the case of other
         defaults) or may provide for an immediate enforcement upon such default
         or may limit the remedies available to the Trustee upon such default or
         may limit the right of the Holders of a majority in aggregate principal
         amount of that or those series of Securities to which such additional
         Events of Default apply to waive such default; or

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

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

                           (6) to secure the Securities; or

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

                           (8) to evidence and provide for the acceptance of
         appointment hereunder by a successor Trustee with respect to the
         Securities of one or more series and to add to or change any of the
         provisions of this Indenture as shall be necessary to provide for or
         facilitate the administration of the trusts hereunder by more than one
         Trustee; or

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

                           (10) to supplement any of the provisions of this
         Indenture to such extent as shall be necessary to permit or facilitate
         the defeasance and discharge of any series of Securities pursuant to
         Sections 401, 1402 and 1403; provided that any such

                                       58
<PAGE>   66
         action shall not adversely affect the interests of the Holders of
         Securities of such series and any related coupons or any other series
         of Securities in any material respect.

         SECTION 902. Supplemental Indentures with Consent of Holders. With the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Securities affected by such supplemental indenture, by Act of said
Holders delivered to the Partnership and the Trustee, the Partnership, when
authorized by or pursuant to a Board Resolution, and the Trustee may enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities and any related coupons under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

                           (1) change the Stated Maturity of the principal of
         (or premium, if any, on) or any installment of principal of or interest
         on, any Security; or reduce the principal amount thereof or the rate or
         amount of interest thereon or any Additional Amounts payable in respect
         thereof, or any premium payable upon the redemption thereof, or change
         any obligation of the Partnership to pay Additional Amounts pursuant to
         Section 1009 (except as contemplated by Section 801(1) and permitted by
         Section 901(1)), or reduce the amount of the principal of an Original
         Issue Discount Security that would be due and payable upon a
         declaration of acceleration of the Maturity thereof pursuant to Section
         502 or the amount thereof provable in bankruptcy pursuant to Section
         504, or adversely affect any right of repayment at the option of the
         Holder of any Security, or change any Place of Payment where, or the
         currency or currencies, currency unit or units or composite currency or
         currencies in which, any Security or any premium or the interest
         thereon is payable, or impair the right to institute suit for the
         enforcement of any such payment on or after the Stated Maturity thereof
         (or, in the case of redemption or repayment at the option of the
         Holder, on or after the Redemption Date or the Repayment Date, as the
         case may be), or

                           (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver with respect to such series (or
         compliance with certain provisions of this Indenture or certain
         defaults hereunder and their consequences) provided for in this
         Indenture, or reduce the requirements of Section 1504 for quorum or
         voting, or

                           (3) modify any of the provisions of this Section ,

         Holder of each Outstanding Security affected thereby.

         It shall not be necessary for any Act of Holders under this Section to
         approve the

                                       59
<PAGE>   67
particular form of any proposed supplemental indenture, but it shall be
sufficient if such Act shall approve the substance thereof.

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

         SECTION 903. Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

         SECTION 904. Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified
in accordance therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder and of any coupon appertaining
thereto shall be bound thereby.

         SECTION 905. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

         SECTION 906. Reference in Securities to Supplemental Indentures.
Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall, if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Partnership shall so
determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Partnership, to any such supplemental indenture
may be prepared and executed by the Partnership and authenticated and delivered
by the Trustee in exchange for Outstanding Securities of such series.


                             ARTICLE TEN - COVENANTS

         SECTION 1001. Payment of Principal, Premium, if any; Interest and
Additional Amounts. The Partnership covenants and agrees for the benefit of the
Holders of each series of Securities that it will duly and punctually pay the
principal of (and premium, if any) and interest on and any Additional Amounts
payable in respect of the Securities of that series in

                                       60
<PAGE>   68
accordance with the terms of such series of Securities, any coupons appertaining
thereto and this Indenture. Unless otherwise specified as contemplated by
Section 301 with respect to any series of Securities, any interest due on and
any Additional Amounts payable in respect of Bearer Securities on or before
Maturity, other than Additional Amounts, if any, payable as provided in Section
1009 in respect of principal of (or premium, if any, on) such a Security, shall
be payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature. Unless
otherwise specified with respect to Securities of any series pursuant to Section
301, at the option of the Partnership, all payments of principal may be paid by
check to the registered Holder of the Registered Security or other person
entitled thereto against surrender of such Security.

         SECTION 1002. Maintenance of Office or Agency. If Securities of a
series are issuable only as Registered Securities, the Partnership shall
maintain in each Place of Payment for any series of Securities an office or
agency where Securities of that series may be presented or surrendered for
payment, where Securities of that series may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Partnership in
respect of the Securities of that series and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Partnership will
maintain: (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment, where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange, where notices and demands to or upon the Partnership
in respect of the Securities of that series and this Indenture may be served and
where Bearer Securities of that series and related coupons may be presented or
surrendered for payment in the circumstances described in the following
paragraph (and not otherwise); (B) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States, an office or agency where Securities of that series and related
coupons may be presented and surrendered for payment (including payment of any
Additional Amounts payable on Securities of that series pursuant to Section
1009); provided, however, that if the Securities of that series are listed on
any stock exchange located outside the United States and such stock exchange
shall so require, the Partnership will maintain a Paying Agent for the
Securities of that series in any required city located outside the United
States, as the case may be, so long as the Securities of that series are listed
on such exchange; and (C) subject to any laws or regulations applicable thereto,
in a Place of Payment for that series located outside the United States an
office or agency where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange and where notices and demands to or upon the
Partnership in respect of the Securities of that series and this Indenture may
be served. The Partnership will give prompt written notice to the Trustee of the
location, and any change in the location, of each such office or agency. If at
any time the Partnership shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of that
series and the related coupons may

                                       61
<PAGE>   69
be presented and surrendered for payment (including payment of any Additional
Amounts payable on Bearer Securities of that series pursuant to Section 1009) at
the offices specified in the Security, in London, England, and the Partnership
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands, and the Partnership hereby appoints the Trustee
its agent to receive all such presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on or Additional
Amounts in respect of Bearer Securities shall be made at any office or agency of
the Partnership in the United States or by check mailed to any address in the
United States or by transfer to an account maintained with a bank located in the
United States; provided, however, that, if the Securities of a series are
payable in Dollars, payment of principal of and any premium and interest on any
Bearer Security (including any Additional Amounts payable on Securities of such
series pursuant to Section 1009) shall be made at the office of the
Partnership's Paying Agent in the Borough of Manhattan, The City of New York, if
(but only if) payment in Dollars of the full amount of such principal, premium,
interest or Additional Amounts, as the case may be, at all offices or agencies
outside the United States maintained for the purpose by the Partnership in
accordance with this Indenture, is illegal or effectively precluded by exchange
controls or other similar restrictions.

         The Partnership may from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all of such purposes, and may from time to time
rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Partnership of its obligation to
maintain an office or agency in accordance with the requirements set forth above
for Securities of any series for such purposes. The Partnership will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency. Unless otherwise
specified with respect to any Securities pursuant to Section 301 with respect to
a series of Securities, the Partnership hereby designates as a Place of Payment
for each series of Securities the office or agency of the Partnership in the
Borough of Manhattan, The City of New York, and initially appoints the Trustee
at its Corporate Trust Office as Paying Agent in such city and as its agent to
receive all such presentations, surrenders, notices and demands.

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

         SECTION 1003. Money for Securities Payments to Be Held in Trust. If the
Partnership shall at any time act as its own Paying Agent with respect to any
series of any

                                       62
<PAGE>   70
Securities and any related coupons, it will, on or before each due date of the
principal of (and premium, if any), or interest on or Additional Amounts in
respect of, any of the Securities of that series, segregate and hold in trust
for the benefit of the Persons entitled thereto a sum in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay the
principal (and premium, if any) or interest or Additional Amounts so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided, and will promptly notify the Trustee of its action or failure
so to act.

         Whenever the Partnership shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium, if any), or interest on or Additional
Amounts in respect of, any Securities of that series, deposit with a Paying
Agent a sum (in the currency or currencies, currency unit or units or composite
currency or currencies described in the preceding paragraph) sufficient to pay
the principal (and premium, if any) or interest or Additional Amounts, so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest or Additional Amounts and
(unless such Paying Agent is the Trustee) the Partnership will promptly notify
the Trustee of its action or failure so to act.

         The Partnership will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will

                           (1) hold all sums held by it for the payment of
         principal of (and premium, if any) or interest on Securities in trust
         for the benefit of the Persons entitled thereto until such sums shall
         be paid to such Persons or otherwise disposed of as herein provided;

                           (2) give the Trustee notice of any default by the
         Partnership (or any other obligor upon the Securities) in the making of
         any such payment of principal (and premium, if any) or interest on the
         Securities of that series; and

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

         The Partnership may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by 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

                                       63
<PAGE>   71
respect to such sums.

         Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Partnership,
in trust for the payment of the principal of (and premium, if any) or interest
on, or any Additional Amounts in respect of, any Security of any series and
remaining unclaimed for two years after such principal (and premium, if any),
interest or Additional Amounts has become due and payable shall be paid to the
Partnership upon Partnership Request or (if then held by the Partnership) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Partnership for payment of
such principal of (and premium, if any) or interest on, or any Additional
Amounts in respect of, any Security, without interest thereon, and all liability
of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Partnership as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Partnership cause to be
published once, in an Authorized Newspaper, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Partnership.

         SECTION 1004. Existence. Subject to Article Eight, the Partnership will
do or cause to be done all things necessary to preserve and keep in full force
and effect its limited partnership existence, all material rights (by agreement
of limited partnership and statute) and material franchises; provided, however,
that the Partnership shall not be required to preserve any such right or
franchise if the Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the
Partnership.

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

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

         SECTION 1007. Payment of Taxes and Other Claims. The Partnership will
pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or

                                       64
<PAGE>   72
upon the income, profits or property of the Partnership or any Subsidiary, and
(2) all lawful claims for labor, materials and supplies which, if unpaid, might
by law become a lien upon the property of the Partnership or any Subsidiary;
provided, however, that the Partnership shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings.

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

         SECTION 1009. Additional Amounts. If any Securities of a series provide
for the payment of Additional Amounts, the Partnership will pay to the Holder of
any Security of such series or any coupon appertaining thereto Additional
Amounts as may be specified as contemplated by Section 301. Whenever in this
Indenture there is mentioned, in any context except in the case of Section
502(1), the payment of the principal of or any premium or interest on, or in
respect of, any Security of any series or payment of any related coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established pursuant to Section 301
to the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof pursuant to such terms and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding Additional Amounts in those provisions hereof where
such express mention is not made.

         Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate, the Partnership will furnish
the Trustee and the Partnership's principal Paying Agent or Paying Agents, if
other than the Trustee, with an Officers' Certificate instructing the Trustee
and such Paying Agent or Paying Agents whether such payment of principal of and
any premium or interest on the Securities of that series shall be made to
Holders of Securities of that series or any related coupons who are not United
States persons without withholding for or on account of any tax, assessment or
other governmental charge described in the Securities of the series. If any such
withholding shall be

                                       65
<PAGE>   73
required, then such Officers' Certificate shall specify by country the amount,
if any, required to be withheld on such payments to such Holders of Securities
of that series or related coupons and the Partnership will pay to the Trustee or
such Paying Agent the Additional Amounts required by the terms of such
Securities. In the event that the Trustee or any Paying Agent, as the case may
be, shall not so receive the above-mentioned certificate, then the Trustee or
such Paying Agent shall be entitled (i) to assume that no such withholding or
deduction is required with respect to any payment of principal or interest with
respect to any Securities of a series or related coupons until it shall have
received a certificate advising otherwise and (ii) to make all payments of
principal and interest with respect to the Securities of a series or related
coupons without withholding or deductions until otherwise advised. The
Partnership covenants to indemnify the Trustee and any Paying Agent for, and to
hold them harmless against, any loss, liability or expense reasonably incurred
without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them or in reliance on any Officers'
Certificate furnished pursuant to this Section or in reliance on the
Partnership's not furnishing such an Officers' Certificate.

         SECTION 1010. Waiver of Certain Covenants. The Partnership may omit in
any particular instance to comply with any term, provision or condition set
forth in Sections 1004 to 1007, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Partnership and the duties of the
Trustee in respect of any such term, provision or condition shall remain in full
force and effect.


                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

         SECTION 1101. Applicability of Article. Securities of any series which
are redeemable before their Stated Maturity shall be redeemable in accordance
with their terms and (except as otherwise specified as contemplated by Section
301 for Securities of any series) in accordance with this Article.

         SECTION 1102. Election to Redeem; Notice to Trustee. The election of
the Partnership to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution. In case of any redemption at the election of the Partnership
of less than all of the Securities of any series, the Partnership shall, at
least 45 days prior to the giving of the notice of redemption in Section 1104
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities prior to
the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Partnership shall furnish
the Trustee with an Officers' Certificate evidencing

                                       66
<PAGE>   74
compliance with such restriction.

         SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If
less than all the Securities of any series issued on the same day with the same
terms are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series issued on such date with the same
terms not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
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 and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

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

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

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

         All notices of redemption shall state:

                           (1) the Redemption Date,

                           (2) the Redemption Price, accrued interest to the
         Redemption Date payable as provided in Section 1106, if any, and
         Additional Amounts, if any,

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

                                       67
<PAGE>   75
                           (4) in case any Security is to be redeemed in part
         only, the notice which relates to such Security shall state that on and
         after the Redemption Date, upon surrender of such Security, the holder
         will receive, without a charge, a new Security or Securities of
         authorized denominations for the principal amount thereof remaining
         unredeemed,

                           (5) that on the Redemption Date the Redemption Price
         and accrued interest to the Redemption Date payable as provided in
         Section 1106, if any, will become due and payable upon each such
         Security, or the portion thereof, to be redeemed and, if applicable,
         that interest thereon shall cease to accrue on and after said date,

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

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

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

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

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

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

         SECTION 1105. Deposit of Redemption Price. On or prior to any
Redemption Date, the Partnership shall deposit with the Trustee or with a Paying
Agent (or, if the Partnership is acting as its own Paying Agent, which it may
not do in the case of a sinking fund payment under Article Twelve, segregate and
hold in trust as provided in Section 1003) an amount of money in the currency or
currencies, currency unit or units or composite currency or

                                       68
<PAGE>   76
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
sufficient to pay on the Redemption Date the Redemption Price of, and (except if
the Redemption Date shall be an Interest Payment Date) accrued interest on, all
the Securities or portions thereof which are to be redeemed on that date.

         SECTION 1106. Securities Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Partnership shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void. Upon surrender of
any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Partnership at the Redemption Price, together
with accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
that installments of interest on Registered Securities whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Partnership and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for

                                       69
<PAGE>   77
redemption, the principal (and premium, if any) shall, until paid, bear interest
from the Redemption Date at the rate borne by the Security.

         SECTION 1107. Securities Redeemed in Part. Any Registered Security
which is to be redeemed only in part (pursuant to the provisions of this Article
or of Article Twelve) shall be surrendered at a Place of Payment therefor (with,
if the Partnership or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Partnership and the Trustee
duly executed by, the Holder thereof or his attorney duly authorized in writing)
and the Partnership shall execute and the Trustee shall authenticate and deliver
to the Holder of such Security without service charge a new Security or
Securities of the same series, of any authorized denomination as requested by
such Holder in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered. If a Global
Security is so surrendered, the Partnership shall execute and the Trustee shall
authenticate and deliver to the depositary, without service charge, a new Global
Security in a denomination equal to and in exchange for the unredeemed portion
of the principal of the Global Security so surrendered.


                         ARTICLE TWELVE - SINKING FUNDS

         SECTION 1201. Applicability of Article. The provisions of this Article
shall be applicable to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

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

         SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.
The Partnership may, in satisfaction of all or any part of any mandatory sinking
fund payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Partnership pursuant to
the terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Partnership; provided that such Securities so delivered or applied as a credit
have not been previously so credited. Such

                                       70
<PAGE>   78
Securities shall be received and credited for such purpose by the Trustee at the
applicable Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund
payment shall be reduced accordingly.

         SECTION 1203. Redemption of Securities for Sinking Fund. Not less than
60 days prior to each sinking fund payment date for Securities of any series,
the Partnership will deliver to the Trustee an Officers' Certificate specifying
the amount of the next ensuing mandatory sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Partnership shall thereupon be obligated to pay the
amount therein specified. Not less than 30 days before each such sinking fund
payment date the Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Partnership in the manner provided in Section 1104. Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1106 and 1107.


              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

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

         SECTION 1302. Repayment of Securities. Securities of any series subject
to repayment in whole or in part at the option of the Holders thereof will,
unless otherwise provided in the terms of such Securities, be repaid at a price
equal to the principal amount thereof, together with interest, if any, thereon
accrued to the Repayment Date specified in or pursuant to the terms of such
Securities. The Partnership covenants that on or prior to the Repayment Date it
will deposit with the Trustee or with a Paying Agent (or, if the Partnership is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and

                                       71
<PAGE>   79
(except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date.

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

         SECTION 1304. When Securities Presented for Repayment Become Due and
Payable. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Partnership on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Partnership shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to

                                       72
<PAGE>   80
any Bearer Securities so to be repaid, except to the extent provided below,
shall be void. Upon surrender of any such Security for repayment in accordance
with such provisions, together with all coupons, if any, appertaining thereto
maturing after the Repayment Date, the principal amount of such Security so to
be repaid shall be paid by the Partnership, together with accrued interest, if
any, to the Repayment Date; provided, however, that coupons whose Stated
Maturity is on or prior to the Repayment Date shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified pursuant to Section 301, only upon
presentation and surrender of such coupons; and provided further that, in the
case of Registered Securities, installments of interest, if any, whose Stated
Maturity is on or prior to the Repayment Date shall be payable (but without
interest thereon, unless the Partnership shall default in the payment thereof)
to the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

         If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Partnership and the Trustee if there be furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security shall surrender to the
Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made as provided in the preceding sentence, such
Holder shall be entitled to receive the amount so deducted; provided, however,
that interest represented by coupons shall be payable only at an office or
agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

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

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

              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401. Applicability of Article: Partnership's Option to Effect
Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this
Article (with such modifications thereto as may be specified pursuant to Section
301 with respect to any Securities), shall be applicable to such Securities and
any coupons appertaining thereto, and the Partnership may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.

         SECTION 1402. Defeasance and Discharge. Upon the Partnership's exercise
of the above option applicable to this Section with respect to any Securities of
or within a series, the Partnership shall be deemed to have been discharged from
its obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Partnership shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Partnership, shall execute
proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section , payments in respect of the principal of (and
premium, if any) and interest, if any, on such Securities and any coupons
appertaining thereto when such payments are due, (B) the Partnership's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003 and with respect to the payment of Additional Amounts, if any, on such
Securities as contemplated by Section 1009, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article. Subject to
compliance with this Article Fourteen, the Partnership may exercise its option
under this Section notwithstanding the prior exercise of its option under
Section 1403 with respect to such Securities and any coupons appertaining
thereto.

         SECTION 1403. Covenant Defeasance. Upon the Partnership's exercise of
the above option applicable to this Section with respect to any Securities of or
within a series, the Partnership shall be released from its obligations under
Sections 1004 to 1007, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant, with respect to

                                       74
<PAGE>   82
such Outstanding Securities and any coupons appertaining thereto on and after
the date the conditions set forth in Section 1404 are satisfied (hereinafter,
"covenant defeasance"), and such Securities and any coupons appertaining thereto
shall thereafter be deemed to be not "Outstanding" for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the
consequences of any thereof) in connection with Sections 1004 to 1007,
inclusive, or such other covenant, but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to such Outstanding Securities and any coupons
appertaining thereto, the Partnership may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Section or such other covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such Section or such other covenant or by
reason of reference in any such Section or such other covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a default or an Event of Default under Section 501(4) or 501(8) or
otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities and any coupons appertaining thereto shall be
unaffected thereby.

         SECTION 1404. Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

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

                                       75
<PAGE>   83
payments are due and payable in accordance with the terms of this Indenture and
of such Securities and any coupons appertaining thereto.

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

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

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

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

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

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

                                       76
<PAGE>   84
conditions or limitations which may be imposed on the Partnership in connection
therewith pursuant to Section 301.

         SECTION 1405. Deposited Money and Government Obligations to Be Held in
Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Partnership acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium, if any) and interest and Additional Amounts, if any, but such money
need not be segregated from other funds except to the extent required by law.

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

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

         Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Partnership from time to
time upon Partnership Request any money or Government Obligations (or other
property and any proceeds therefrom) held by it

                                       77
<PAGE>   85
as provided in Section 1404 which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof which
would then be required to be deposited to effect a defeasance or covenant
defeasance, as applicable, in accordance with this Article.

as aforesaid by the affirmative vote of the Holders of such specified percentage
in principal amount of the Outstanding Securities of that series.

         been made, given or taken under this Indenture.

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

                  (b) The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Partnership or by Holders of Securities as provided in Section 1502(b), in
which case the Partnership or the Holders of Securities of the series calling

chairman. A permanent chairman and a permanent secretary of the meeting shall be

of the Outstanding Securities of such series represented at the meeting.

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

called pursuant to Section 1502 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of
the Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further

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

         SECTION 1601. Agreement to Subordinate. The Partnership agrees, and
each Holder by accepting a Security agrees, that the indebtedness evidenced by
the Securities is subordinated in right of payment, to the extent and in the
manner provided in this Article, to the prior payment in full of all Senior Debt
and that the subordination is for the benefit of the holders of Senior Debt.

         SECTION 1602. Liquidation; Dissolution; Bankruptcy. Upon any
distribution to creditors of the Partnership in a liquidation or dissolution of
the Partnership or in a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to the Partnership or its property:

         receive payment in full in cash of the principal of and interest
         (including interest accruing after the commencement of any such
         proceeding) to the date of payment on the Senior Debt before Holders

         Securities; and

                           (2) until the Senior Debt is paid in full in cash,
         any distribution to which Holders would be entitled but for this
         Article shall be made to holders of Senior

         Debt as their interests may appear, except that Holders may receive
         securities that are subordinated to Senior Debt to at least the same
         extent as the Securities.

         SECTION 1603. Default on Senior Debt. The Partnership may not pay
principal of or interest on the Securities and may not acquire any Securities
for cash or property other than partnership interests of the Partnership if:

                           (1) a default on Senior Debt occurs and is continuing
         that permits holders of such Senior Debt to accelerate its maturity,
         and

                           (2) the default is the subject of judicial
         proceedings or the Partnership receives a notice of the default from a
         person who may give it pursuant to Section 1611. If the Partnership
         receives any such notice, a similar notice received within nine months
         thereafter relating to the same default on the same issue of Senior
         Debt shall not be effective for purposes of this Section.

         If this Article otherwise permits the payment or acquisition at the
time, the Partnership may resume payments on the Securities and may acquire them
when:

                  (a) the default is cured or waived, or

                  (b) 120 days pass after the notice is given if the default is
not the subject of judicial proceedings.

         SECTION 1604. Acceleration of Securities. If payment of the Securities
is accelerated because of an Event of Default, the Partnership shall promptly
notify holders of Senior Debt of the acceleration. The Partnership may pay the
Securities when 120 days pass after the acceleration occurs if this Article
permits the payment at that time.

         SECTION 1605. When Distribution Must Be Paid Over. If a distribution is
made to Holders that because of this Article should not have been made to them,
the Holders who receive the distribution shall hold it in trust for holders of
Senior Debt and pay it over to them as their interests may appear.

         SECTION 1606. Notice by Partnership. The Partnership shall promptly
notify the Trustee and any Paying Agent of any facts known to the Partnership
that would cause a payment of principal of or interest on Securities to violate
this Article.

         SECTION 1607. Subrogation. After all Senior Debt is paid in full and
until the Securities are paid in full, Holders shall be subrogated to the rights
of holders of Senior Debt to receive distributions applicable to Senior Debt to
the extent that distributions otherwise payable to the Holders have been applied
to the payment of Senior Debt. A distribution made under this Article to holders
of Senior Debt which otherwise would have been made to

                                       82
<PAGE>   90
Holders is not, as between the Partnership and Holders, a payment by the
Partnership on Senior Debt.

         SECTION 1608. Relative Rights. This Article defines the relative rights
of Holders and holders of Senior Debt. Nothing in this Indenture shall:

                           (1) impair, as between the Partnership and Holders,
         the obligation of the Partnership, which is absolute and unconditional,
         to pay principal of and interest on the Securities in accordance with
         their terms;

                           (2) affect the relative rights of Holders and
         creditors of the Partnership other than holders of Senior Debt; or

                           (3) prevent the Trustee or any Holder from exercising
         its available remedies upon an Event of Default, subject to the rights
         of holders of Senior Debt to receive distributions otherwise payable to
         Holders of Securities.

         If the Partnership fails because of this Article to pay principal of or
interest on a Security on the due date, the failure is still a default.

         SECTION 1609. Subordination May Not Be Impaired by Trust. No right of
any holder of Senior Debt to enforce the subordination of the indebtedness
evidenced by the Securities shall be impaired by any act or failure to act by
the Partnership or by its failure to comply with this Indenture.

         SECTION 1610. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Senior Debt, the
distribution may be made and the notice given to their Representative.

         SECTION 1611. Rights of Trustee and Paying Agent. The Trustee or any
Paying Agent may continue to make payments on the Securities until it receives
notice of facts that would cause a payment of principal of or interest on the
Securities to violate this Article. Only the Partnership, a Representative or a
holder of an issue of Senior Debt that has no Representative may give the
notice.

         The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee.

This Security is one of a duly authorized issue of subordinated securities of
the Partnership (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of _____________, 199_ (herein
called the "Indenture") between the Partnership and _________________, as

under the Indenture with respect to the series of which this Security is a
part), to which Indenture and all indentures supplemental thereto reference is
hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Partnership, the Trustee and the Holders
of the Securities, and of the terms upon which the Securities are, and are to

the Securities to be issued under such series is limited to $______ (except for

business on the relevant Record Dates referred to on the face hereof, all as
provided in the Indenture.]

         [If applicable, insert -- The Securities are subject to redemption (1)

and thereafter at a Redemption Price equal to ____% of the principal amount,
together in the case of any such redemption (whether through operation of the
sinking fund or otherwise) with accrued interest to the Redemption Date;
provided, however, that installments of interest on this Security whose Stated
Maturity is on or prior to such Redemption Date will be payable to the Holder of
this Security, or one or more Predecessor Securities, of record at the close of
business on the relevant Record Dates referred to on the face hereof, all as
provided in the Indenture.]

         [If applicable, insert -- Notwithstanding the foregoing, the
Partnership may not, prior to _______, redeem any Securities as contemplated by

refunding operation by the application, directly or indirectly, of moneys
borrowed having an interest cost to the Partnership (calculated in accordance
with generally accepted financial practice) of less than __% per annum.]

         [If applicable, insert -- The sinking fund for the Securities provides

<PAGE>   99
order in which they become due.]]

         Notice of redemption will be given by mail to Holders of Securities,
not less than 30 nor more than 60 days prior to the Redemption Date, all as
provided in the Indenture.

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

         The indebtedness evidenced by this Security is, to the extent and in
the manner set forth in the Indenture, expressly subordinated and subject in
right of payment to the prior payment in full of all Senior Debt, and this
Security is issued subject to such provisions of the Indenture. Each Holder of
this Security, by accepting the same, agrees to and shall be bound by such
provisions of the Indenture and authorizes and directs the Trustee on his behalf
to take such action as may be necessary or appropriate to effectuate such
subordination as provided in the Indenture and appoints the Trustee his
attorney-in-fact for any and all such purposes.

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

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Partnership,
which is absolute and unconditional, to pay the principal of (and premium, if
any) and interest on this Security at the times, places and rate, and in the
coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
[and herein] set forth, the transfer of this Security is registrable in the
Security Register of the Partnership upon surrender of this Security for
registration of transfer at the office or agency of the Partnership in any place
where the principal of (and premium, if any) and interest on this

                                       A-7
<PAGE>   100
Security are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Partnership and the Security Registrar
duly executed by, the Holder hereof or by his attorney duly authorized in
writing, and thereupon one or more new Securities, of authorized denominations
and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

         As provided in the Indenture and subject to certain limitations therein
[and herein] set forth, this Security is exchangeable for a like aggregate
principal amount of Securities of different authorized denominations but
otherwise having the same terms and conditions, as requested by the Holder
hereof surrendering the same.

         The Securities of this series are issuable only in registered form

         No service charge shall be made for any such registration of transfer

cover any tax or other governmental charge payable in connection therewith,

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

                  Notwithstanding anything contained herein to the contrary, no
recourse under or upon any obligation, covenant or agreement contained in this
Security, or because of any indebtedness evidenced hereby, or for any claim
based hereon or otherwise in respect hereof, shall be had for the payment of the
principal of or premium, if any, or the interest on this Security, or for any
claim based hereon, or otherwise in respect hereof, or based on or in respect of
the Indenture or any indenture supplemental thereto, against (i) the Company or
any other past, present or future partner in the Partnership, (ii) against any
other Person which owns an interest, directly or indirectly, in any partner of
the Partnership or (iii) against any past, present or future stockholder,
employee, officer or director, as such, of the Company, or of any successor,
either directly or through the Partnership or the Company or any successor,
whether by virtue of any constitution, statute or rule of law or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

         The Indenture and the Securities shall be governed by and construed in
accordance with the laws of [The State of New York] applicable to agreements
made and to be performed entirely in such State.

         Re:      Legality of Securities to be Registered Under
                  Registration Statement on Form S-3
                  ---------------------------------------------

Ladies and Gentlemen:

     This opinion is furnished in connection with the registration statement on
Form S-3 (the "Registration Statement") pursuant to the Securities Act of 1933,
as amended (the "Securities Act"), relating to an indeterminate amount of (i)
shares of common stock, $.01 par value per share (the "Common Stock"), and
shares of preferred stock, $.01 par value per share (the "Preferred Stock"), of
Summit Properties Inc. (the "Company") with an aggregate public offering price
of up to $250,000,000, and (ii) debt securities (the "Debt Securities") of
Summit Properties Partnership, L.P. (the "Operating Partnership") with an
aggregate public offering price of up to $250,000,000 (such securities being
referred to collectively as the "Securities"). The Registration Statement
provides that the Securities may be offered separately or together, in separate
series, in amounts, at prices and on terms to be set forth in one or more
prospectus supplements (each a "Prospectus Supplement") to the Prospectus
contained in the Registration Statement.

     In connection with rendering this opinion, we have examined the Articles of
Incorporation of the Company, as amended and restated to the date hereof and on
file with the Maryland State Department of Assessments and Taxation; the Bylaws
of the Company, as amended to the date hereof; the Agreement of Limited
Partnership of the Operating Partnership, as amended to the date hereof; such
records of the corporate and partnership proceedings of the Company and the
Operating Partnership, respectively, as we deemed material; the Registration
Statement and the exhibits thereto; and such other certificates, receipts,
records and documents as we considered necessary for the purposes of this
opinion. In our examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as certified, photostatic or facsimile copies, the authenticity
of the originals of such copies and the authenticity of telephonic confirmations
of public officials and

others. As to facts material to our opinion, we have relied upon certificates or
telephonic confirmations of public officials and certificates, documents,
statements and other information of the Company or the Operating Partnership or
respective representatives or officers thereof.

     We are attorneys admitted to practice in The Commonwealth of Massachusetts.
We express no opinion concerning the laws of any jurisdictions other than the
laws of the United States of America, the laws of The Commonwealth of
Massachusetts, the Maryland General Corporation Law and the Delaware Revised
Uniform Limited Partnership Act, and also express no opinion with respect to the
blue sky or securities laws of any state, including Massachusetts, Maryland and
Delaware.

     Based upon the foregoing, we are of the opinion that:

     (1)   Under the Maryland General Corporation Law, pursuant to which the
Company was incorporated, when specifically authorized for issuance by the
Company's Board of Directors or an authorized committee thereof (the "Board
Authorization") and when issued as described in the Registration Statement and a
Prospectus Supplement that is consistent with the Board Authorization, and upon
receipt by the Company of the consideration provided for in the Board
Authorization (which consideration is not less than the $.01 par value per
share), the Common Stock and the Preferred Stock covered by the Registration
Statement will be legally issued, fully paid and nonassessable.

     (2)   Under the Delaware Revised Uniform Limited Partnership Act, pursuant
to which the Operating Partnership was formed, when specifically authorized for
issuance by the general partner of the Operating Partnership (the "General
Partner Authorization") and when issued as described in the Registration
Statement and a Prospectus Supplement that is consistent with the General
Partner Authorization, and upon receipt by the Operating Partnership of the
consideration provided for in the General Partner Authorization, the Debt
Securities will be binding obligations of the Operating Partnership.

     The foregoing assumes that all requisite steps will be taken to comply with
the requirements of the Securities Act and applicable requirements of state laws
regulating the offer and sale of securities.

         Re:      Certain Federal Income Tax Matters

Ladies and Gentlemen:

         This opinion is delivered to you in our capacity as counsel to Summit
Properties Inc. (the "Company") in connection with the Company's registration
statement on Form S-3 (the "Registration Statement") filed by the Company with
the Securities and Exchange Commission under the Securities Act of 1933, as
amended, relating to the possible offering and sale of (i) shares of common
stock, $.01 par value per share, and shares of preferred stock, $.01 par value
per share, of the Company with an aggregate public offering price of up to
$250,000,000, and debt securities of Summit Properties Partnership, L.P. with
an aggregate public offering price of up to $250,000,000, authorized for        
issuance under the Company's Articles of Incorporation and Summit Properties
Partnership L.P.'s Agreement of Partnership. This opinion relates to the
Company's qualification for federal income tax purposes as a real estate
investment trust ("REIT") under the Internal Revenue Code of 1986, as amended
(the "Code") and the accuracy of the discussion under the heading "Federal
Income Tax Considerations" contained in the Registration Statement.

         In rendering the following opinion, we have examined the Articles of
Incorporation and Bylaws of the Company, each as amended, the Company's federal
income tax return for each of the taxable years ended December 1994 and December
1995 filed on Forms 1120-REIT, and such other records, certificates and
documents as we have deemed necessary or appropriate for purposes of rendering
the opinions set forth herein.

         We have reviewed the Registration Statement and the descriptions set
forth therein of the Company and its investments and activities. We have relied
upon the representations of an officer of the Company regarding the manner in
which the Company has been and will continue to be owned and operated. We assume
that the Company has been and will be operated in accordance with applicable
laws and the terms and conditions of applicable documents, and that the
descriptions of the Company and its investments, and the proposed investments,
activities, operations and governance of the Company set forth in the
Registration

Statement continue to be true. In addition, we have relied on certain additional
facts and assumptions described below.

         In rendering the opinions set forth herein, we have assumed (i) the
genuineness of all signatures on documents we have examined, (ii) the
authenticity of all documents submitted to us as originals, (iii) the conformity
to the original documents of all documents submitted to us as copies, (iv) the
conformity of final documents to all documents submitted to us as drafts, (v)
the authority and capacity of the individual or individuals who executed any
such documents on behalf of any person, (vi) the accuracy and completeness of
all records made available to us, and (vii) the factual accuracy of all
representations, warranties and other statements made by all parties. We have
also assumed, without investigation, that all documents, certificates,
warranties and covenants on which we have relied in rendering the opinion set
forth below and that were given or dated earlier than the date of this letter
continue to remain accurate, insofar as relevant to the opinion set forth
herein, from such earlier date through and including the date of this letter.

         The discussion and conclusions set forth below are based upon the Code,
the Income Tax Regulations and Procedure and Administration Regulations
promulgated thereunder and existing administrative and judicial interpretations
thereof, all of which are subject to change. No assurance can therefore be given
that the federal income tax consequences described below will not be altered in
the future.

         Based upon and subject to the foregoing, and provided that the Company
continues to meet the applicable asset composition, source of income,
shareholder diversification, distribution, recordkeeping and other requirements
of the Code necessary for a corporation to qualify as a REIT, we are of the
opinion that

         1.       Commencing with the Company's first taxable year ended
                  December 31, 1994, the Company has been organized in
                  conformity with the requirements for qualification as a "real
                  estate investment trust" under the Code, and its method of
                  operation, as described in the representations referred to
                  above will enable it to continue to meet the requirements for
                  qualification and taxation as a "real estate investment trust"
                  under the Code.

         2.       The Statements in the Registration Statement set forth under
                  the caption "Federal Income Tax Considerations" to the extent
                  such information constitutes matters of law, summaries of
                  legal matters, or legal conclusions, have been reviewed by us
                  and are accurate in all material respects.

         We express no opinion with respect to the transactions described in the
Registration Statement other than those expressly set forth herein. You should
recognize that our opinion is not binding on the IRS and that the IRS may
disagree with the opinion contained herein. Although we believe that our opinion
will be sustained if challenged, there can be no assurance that this will be the

the inclusion of a copy of this opinion letter as an exhibit to the Registration
