J.P. MORGAN SECURITIES INC.
ON BEHALF OF THE UNDERWRITERS LISTED ON SCHEDULE A HEREOF

c/o J.P. MORGAN SECURITIES INC.
    60 Wall Street
    New York, New York 10260

Dear Ladies and Gentlemen:

         EOP Operating Limited Partnership, a Delaware limited partnership (the
"Operating Partnership"), confirms its agreement with J.P. Morgan Securities
Inc. ("J.P. Morgan") on behalf of the Underwriters listed on Schedule A hereto
(collectively, the "Underwriters," which term shall also include any underwriter
substituted as provided in Section 10 hereof), for whom J.P. Morgan is acting as
representative (in such capacity, the "Representative"), with respect to the
sale by the Operating Partnership and the purchase by the Underwriters, acting
severally and not jointly, of $500,000,000 aggregate principal amount of 8.375%
Notes due March 15, 2006 (the "Securities"). The Securities will be issued
pursuant to an indenture dated as of September 2, 1997 (such indenture, as
supplemented, the "Indenture"), between the Operating Partnership and State
Street Bank and Trust Company, as trustee (the "Trustee"). The Securities will
be issued in book-entry form only to Cede & Co. as nominee of The Depository
Trust Company ("DTC") pursuant to a letter agreement, to be dated as of the
Closing Time (as defined in Section 2(c)) (the "DTC Agreement"), among the
Operating Partnership, the Trustee and DTC. Unless the context otherwise
requires, as used herein, "you" and "your" shall mean the parties to whom this
Underwriting Agreement (this "Agreement") is addressed. Capitalized terms used
herein without definition shall have the meanings assigned to such terms in the
Prospectus (as defined below) relating to the Securities.

                  The Operating Partnership understands that the Underwriters
propose to make a public offering of the Securities as soon as the
Representative deems advisable after this Agreement has been executed.

                  The Operating Partnership has filed with the Securities and
Exchange Commission (the "Commission") a registration statement on Form S-3
(No. 333-58689) covering


<PAGE>


the registration of debt securities, including the Securities, under the
Securities Act of 1933, as amended (the "1933 Act"), including the related
preliminary prospectus or prospectuses. Promptly after execution and delivery of
this Agreement, the Operating Partnership will prepare and file a prospectus
supplement relating to the Securities in accordance with the provisions of Rule
424(b) ("Rule 424(b)") of the rules and regulations of the Commission under the
1933 Act (the "1933 Act Regulations"). Any prospectus supplement relating to the
Securities that omitted certain pricing information and was used after the
effectiveness of such registration statement and prior to the execution and
delivery of this Agreement and the prospectus contained in such registration
statement are collectively referred to as herein as a "preliminary prospectus."
Such registration statement, including the exhibits thereto, schedules thereto,
if any, and the documents incorporated by reference therein pursuant to Item 12
of Form S-3 under the 1933 Act, at the time it became effective, is herein
called the "Registration Statement." Any registration statement filed pursuant
to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule
462(b) Registration Statement," and after such filing the term "Registration
Statement" shall include the Rule 462(b) Registration Statement. The final
prospectus and the prospectus supplement relating to the Securities, including
the documents incorporated by reference therein pursuant to Item 12 of Form S-3
under the 1933 Act, in the form first furnished to the Underwriters for use in
connection with confirming sales of the Securities, are collectively referred to
herein as the "Prospectus." For purposes of this Agreement, all references to
the Registration Statement, any preliminary prospectus or the Prospectus or any
amendment or supplement to any of the foregoing shall be deemed to include the
copy filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval system ("EDGAR").

                  All references in this Agreement to financial statements and
schedules and other information which is "contained," "included," "set forth" or
"stated" in the Registration Statement, any preliminary prospectus or the
Prospectus (or other references of like import) shall be deemed to mean and
include all such financial statements and schedules and other information which
is incorporated by reference in the Registration Statement, any preliminary
prospectus or the Prospectus, as the case may be; and all references in this
Agreement to amendments or supplements to the Registration Statement, any
preliminary prospectus or the Prospectus shall be deemed to mean and include the
filing of any document under the Securities Exchange Act of 1934, as amended
(the "1934 Act"), which is incorporated by reference in the Registration
Statement, such preliminary prospectus or the Prospectus, as the case may be.

                  The "Company" shall mean Equity Office Properties Trust, a
Maryland real estate investment trust, which is the managing general partner of
the Operating Partnership.

                  The Company has entered into an Agreement and Plan of Merger,
dated February 11, 2000 (as the same may have been or may hereafter be amended
or supplemented from time to time, the "Merger Agreement"), with Cornerstone
Properties Inc. ("Cornerstone"), pursuant to which Cornerstone will merge with
and into the Company (the "Merger") and Cornerstone Properties Limited
Partnership, a Delaware limited partnership of which Cornerstone is the sole
general partner will merge with and into the Operating Partnership (the
"Partnership Merger"). The Company will be the surviving entity in the Merger
and the Operating Partnership will be the surviving entity in the Partnership
Merger.

         SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE OPERATING PARTNERSHIP.

         (a) The Operating Partnership represents and warrants to each
Underwriter as of the date hereof and as of the Closing Time, and agrees with
each Underwriter, as follows:

                  (i) COMPLIANCE WITH REGISTRATION REQUIREMENTS. The Operating
         Partnership meets the requirements for use of Form S-3 under the 1933
         Act. The Registration Statement, including any Rule 462(b) Registration
         Statement, has become effective under the 1933 Act and no stop order
         suspending the effectiveness of the Registration Statement has been
         issued under the 1933 Act and no proceedings for that purpose have been
         instituted or are pending or, to the knowledge of the Operating
         Partnership, are contemplated by the Commission, and any request on the
         part of the Commission for additional information has been complied
         with.

                  At the respective times the Registration Statement and any
         post-effective amendments thereto became effective and at the Closing
         Time, the Registration Statement and any amendments thereto complied
         and will comply in all material respects with the requirements of the
         1933 Act and the 1933 Act Regulations and the Trust Indenture Act of
         1939, as amended (the "1939 Act") and the rules and regulations of the
         Commission under the 1939 Act (the "1939 Act Regulations"), and did not
         and will not contain an untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to
         make the statements therein not misleading. Neither the Prospectus nor
         any amendments or supplements thereto, at the time the Prospectus or
         any such amendment or supplement was issued and at the Closing Time,
         included or will include an untrue statement of a material fact or
         omitted or will omit to state a material fact necessary in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading. The representations and
         warranties in this subsection shall not apply to statements in or
         omissions from the Registration Statement or Prospectus made in
         reliance upon and in conformity with information furnished to the
         Operating Partnership in writing by any Underwriter through the
         Representative expressly for use in the Registration Statement or
         Prospectus.

                  Each preliminary prospectus and the prospectus filed as part
         of the Registration Statement as originally filed or as part of any
         amendment thereto, or filed pursuant to Rule 424 under the 1933 Act
         Regulations, complied when so filed in all material respects with the
         1933 Act Regulations, and each preliminary prospectus and the
         Prospectus delivered to the Underwriters for use in connection with
         this offering was identical to the electronically transmitted copies
         thereof filed with the Commission pursuant to EDGAR, except to the
         extent permitted by Regulation S-T.

                  (ii) INCORPORATED DOCUMENTS. The documents incorporated or
         deemed to be incorporated by reference in the Registration Statement
         and the Prospectus, when they became effective or at the time they were
         or hereafter are


                                       3
<PAGE>


         filed with the Commission, complied and will comply in all material
         respects with the requirements of the 1933 Act and the 1933 Act
         Regulations or the 1934 Act and the rules and regulations of the
         Commission thereunder (the "1934 Act Regulations"), as applicable, and,
         when read together with the other information in the Prospectus, at the
         time the Registration Statement became effective, at the time the
         Prospectus was issued and at the Closing Time, did not and will not
         include an untrue statement of a material fact or omit to state a
         material fact necessary in order to make the statements therein, in the
         light of the circumstances under which they were made, not misleading.

                  (iii) INDEPENDENT ACCOUNTANTS. Ernst & Young LLP, the
         accounting firm that certified the financial statements and supporting
         schedules included in the Registration Statement, is an independent
         public accountant as required by the 1933 Act and the 1933 Act
         Regulations.

                  (iv) FINANCIAL STATEMENTS. The financial statements included
         in the Registration Statement and the Prospectus, together with the
         related schedules and notes, present fairly the financial position of
         the respective entity or entities presented therein at the respective
         dates indicated and the results of their operations for the respective
         periods specified, and except as otherwise stated therein, said
         financial statements have been prepared in conformity with generally
         accepted accounting principles ("GAAP") applied on a consistent basis.
         The supporting schedules included in the Registration Statement present
         fairly in accordance with GAAP the information required to be stated
         therein. The financial information and data included in the Prospectus
         and the financial information and data included in the Company's
         Current Report on Form 8-K dated March 15, 2000 present fairly the
         information included therein and have been prepared on a basis
         consistent with that of the books and records of the respective
         entities presented therein. The Statements of Revenues and Certain
         Operating Expenses included in the Prospectus for certain of the
         Properties (as defined below) present fairly the information included
         therein and have been prepared on a basis consistent with that of the
         books and records of the respective entities presented therein.

                  (v) NO MATERIAL ADVERSE CHANGE. Since the respective dates as
         of which information is given in the Registration Statement and the
         Prospectus, except as otherwise stated therein, (A) there has been no
         material adverse change in the condition, financial or otherwise, or in
         the earnings, assets, or business affairs of the Operating Partnership
         and its subsidiaries considered as one enterprise, whether or not
         arising in the ordinary course of business (a "Material Adverse
         Change"), (B) no casualty loss or condemnation or other adverse event
         with respect to any Property has occurred that would result in a
         Material Adverse Effect (as defined below), (C) there have been no
         transactions or acquisitions entered into by the Operating Partnership
         or any of its subsidiaries, other than those arising in the ordinary
         course of business, which are material with respect to the Operating
         Partnership and its subsidiaries considered as one enterprise, (D)
         except as described in the Registration Statement and the Prospectus
         and except


                                       4
<PAGE>


         for regular quarterly distributions on the partnership interests of the
         Operating Partnership, there has been no distribution of any kind
         declared, paid or made by the Operating Partnership with respect to its
         partnership interests, and (E) there has been no material change in the
         partnership interests of the Operating Partnership, or any material
         increase in the indebtedness of the Operating Partnership.

                  (vi) GOOD STANDING OF THE OPERATING PARTNERSHIP. The Operating
         Partnership has been duly formed and is validly existing as a limited
         partnership in good standing under the Delaware Revised Uniform Limited
         Partnership Act (the "Delaware Act") with partnership power and
         authority to own, lease and operate any real property or improvements
         thereon owned or leased by the Operating Partnership or its
         subsidiaries (each individually, a "Property" and collectively, the
         "Properties"), to conduct the business in which it is engaged or
         proposes to engage as described in the Registration Statement and the
         Prospectus and to enter into and perform its obligations under or
         contemplated under this Agreement. The Operating Partnership is duly
         qualified or registered as a foreign partnership and is in good
         standing in each jurisdiction in which such qualification or
         registration is required, whether by reason of the ownership or leasing
         of property or the conduct of business, except where the failure to so
         qualify, register or be in good standing would not result in a material
         adverse effect on the condition, financial or otherwise, or the
         earnings, assets, business affairs or business prospects of the
         Operating Partnership and the its subsidiaries considered as one
         enterprise (a "Material Adverse Effect").

                  (vii) GOOD STANDING OF THE SUBSIDIARIES. Each of the
         subsidiaries of the Operating Partnership listed on SCHEDULE C to this
         Agreement (collectively, the Significant Subsidiaries"), if any, has
         been duly organized and is validly existing as a partnership,
         corporation, limited liability company or real estate investment trust
         in good standing under the laws of its respective jurisdiction of
         organization, with all power and authority to own, lease and operate
         its Properties and to conduct the business in which it is engaged or
         proposes to engage as described in the Registration Statement and the
         Prospectus. Each of the subsidiaries of the Operating Partnership is
         duly qualified or registered as a foreign partnership, corporation,
         limited liability company, or real estate investment trust and is in
         good standing in each jurisdiction in which the business conducted by
         such subsidiary is required and permitted, whether by reason of the
         ownership or leasing of property or the conduct of business, except
         where the failure, singly or in the aggregate, to so qualify would not
         result in a Material Adverse Effect. Each of the partnership or
         operating agreements of the Significant Subsidiaries is in full force
         and effect.

                  (viii) CAPITALIZATION OF OPERATING PARTNERSHIP. The
         capitalization of the Operating Partnership is as set forth in the
         Prospectus as of the date referenced therein. All of the partnership
         interests outstanding at the date hereof were duly authorized for
         issuance by the Operating Partnership and are validly issued and fully
         paid. The outstanding partnership interests were offered


                                       5
<PAGE>


         and sold in compliance with all applicable laws (including, without
         limitation, federal and state securities laws).

         authorized, executed and delivered by, and is a valid and binding
         agreement of, each of the Company and the Operating Partnership,

         duly authorized, executed and delivered by the Operating Partnership,
         and assuming due authorization, execution and delivery by the Trustee,

         Operating Partnership in accordance with their terms, except as (i) the
         enforceability thereof may be limited by bankruptcy, insolvency,
         reorganization, moratorium or similar laws affecting creditors' rights
         generally and (ii) rights of acceleration and the availability of
         equitable remedies may be limited by equitable principles of general

         Statement.

                  (xiii) ABSENCE OF DEFAULTS. Neither the Operating Partnership
         nor any Significant Subsidiary is in violation of its declaration of

         indenture, mortgage, loan agreement, note, lease or other instrument to
         which such entity is a party or by which such entity may be bound, or
         to which any of the property or assets of such entity is subject,
         except where a default thereunder would not result in a Material
         Adverse Effect.

                  (xiv) ABSENCE OF CONFLICTS. The execution and delivery of this
         Agreement and the Indenture, the performance of the obligations set
         forth herein or therein, and the consummation of the transactions
         contemplated hereby or thereby or in the Prospectus (including the
         issuance and sale of the Securities by the Operating Partnership) will
         not result in the creation of any lien, charge or encumbrance upon the
         Properties or conflict with or constitute a breach or violation by the
         Operating Partnership or any of its subsidiaries, or default under,
         (A) any material contract, indenture, mortgage, loan agreement, note,
         lease, joint venture or partnership agreement or other instrument or

         administrative or court decree, except in the cases of clauses (A) and
         (C) for such liens, charges, encumbrances, conflicts, breaches,
         violations or defaults as would not result in a Material Adverse
         Effect.

                  (xv) AUTHORIZATION OF AGREEMENT. The Operating Partnership has
         the requisite power and authority under its organizational documents to
         enter into this Agreement, and this Agreement has been duly authorized,
         executed and delivered by the Operating Partnership.

                  (xvi) ABSENCE OF PROCEEDINGS. There is no action, suit or
         proceeding before or brought by any court or governmental agency or
         body, domestic or foreign, now pending, or, to the knowledge of the
         Operating Partnership, threatened against or affecting the Operating
         Partnership, the Company, any Significant Subsidiary, any Property or
         any officer or trustee of the Company that, if determined adversely to
         the Operating Partnership, the Company, any Significant Subsidiary, any
         Property or any such officer or trustee, might (A) result in any
         Material Adverse Effect or (B) materially and adversely affect the
         consummation of the transactions contemplated by this Agreement. There
         are no legal or governmental proceedings pending or, to the knowledge
         of the Operating Partnership, threatened to which the Operating
         Partnership or any significant subsidiary is a party or to which any of
         their respective assets, properties or operations is the subject that
         are required to be described in the Prospectus that are not so
         described. The aggregate of all pending legal or governmental
         proceedings to which the Operating Partnership, the Company or any
         Significant Subsidiary is a party or of which any of their respective
         assets, properties or operations is the subject which are not described
         in the Prospectus, including ordinary routine litigation incidental to
         the business, could not reasonably be expected to result in a Material
         Adverse Effect.

                  (xvii) ACCURACY OF EXHIBITS. There are no contracts or
         documents which are required to be described in the Registration
         Statement, the Prospectus or the documents incorporated by reference
         therein or to be filed as exhibits thereto which have not been so
         described and filed as required.

                  (xviii) INVESTMENT COMPANY ACT. Neither the Operating
         Partnership nor any Significant Subsidiary is, or at the Closing Time
         will be, required to be registered under the Investment Company Act of
         1940, as amended (the "1940 Act").

                  (xix) POSSESSION OF INTELLECTUAL PROPERTY. The Operating
         Partnership and its subsidiaries own or possess, or can acquire on
         reasonable terms, the trademarks, service marks, trade names, or other
         intellectual property (collectively, "Intellectual Property") necessary
         to carry on the business now operated by them, and no such entity has
         received any notice or is otherwise aware of any infringement of or
         conflict with asserted rights of others with respect to any
         Intellectual Property or of any facts or circumstances which would
         render any Intellectual Property invalid or inadequate to protect the
         interest of such entities therein, and which infringement or conflict
         (if the subject of any unfavorable decision, ruling or finding) or
         invalidity or inadequacy, singly or in the aggregate, would result in a
         Material Adverse Effect.

                  (xx) ABSENCE OF FURTHER REQUIREMENTS. All authorizations,
         approvals and consents of any court or governmental authority or agency
         that are necessary in connection with the offering, issuance or sale of
         the Securities hereunder or the consummation of the other transactions
         contemplated by this Agreement or the Indenture have been obtained,
         except such as have been already obtained or as may be required under
         the securities, blue sky or real estate syndication laws of various
         states in connection with such offer, issuance and sale.

                  (xxi) POSSESSION OF LICENSES AND PERMITS. The Operating
         Partnership and its subsidiaries possess such permits, licenses,
         approvals, consents and other authorizations (collectively,
         "Governmental Licenses") issued by the appropriate federal, state, or
         local regulatory agencies or bodies necessary to conduct the business
         now conducted by them, or proposed to be conducted by them, as
         described in the Prospectus, except where the failure to possess any
         such Governmental License would not have a Material Adverse Effect. The
         Operating Partnership and its subsidiaries are in compliance with the
         terms and conditions of all such Governmental Licenses, except where
         the failure so to comply would not, singly or in the aggregate, result
         in a Material Adverse Effect. All of the Governmental Licenses are
         valid and in full force and effect, except where the invalidity of such
         Governmental Licenses or the failure of such Governmental Licenses to
         be in full force and effect would not result in a Material Adverse
         Effect. Neither the Operating Partnership nor any of its subsidiaries
         has received any notice of proceedings relating to the revocation or
         modification of any such


                                       8
<PAGE>

         Governmental Licenses which, singly or in the aggregate, if the subject
         of an unfavorable decision, ruling or finding, would result in a
         Material Adverse Effect.

                  (xxii) ABSENCE OF LABOR DISPUTE. No labor dispute with the
         employees of the Operating Partnership or any of its subsidiary exists
         or, to the knowledge of the Operating Partnership, is imminent, which
         may reasonably be expected to result in a Material Adverse Effect.

                  (xxiii) TITLE TO PROPERTY. (A) With respect to the Properties
         in which the Operating Partnership owns, directly or indirectly, all of
         the ownership interest therein, the Operating Partnership or its
         subsidiaries have good and marketable fee simple title to the land
         underlying such Properties (or, to the extent described in the
         Prospectus, a valid leasehold estate in such land) and (except for the
         Property known as "500 Orange") good and marketable title to the
         improvements thereon and all other assets that are required for the
         effective operation of such Properties in the manner in which they
         currently are operated, subject, however, to existing mortgages on such
         Properties, to utility easements serving such Properties, to liens of
         ad valorem taxes not due and payable as of the Closing Time (or which
         are being contested pursuant to applicable law), to zoning and similar
         governmental land use matters affecting such Properties that are
         consistent with the current uses of such Properties, to matters of
         title not adversely affecting marketability of title to such
         Properties, other statutory liens not due and payable as of the Closing
         Time, title matters that may be material in character, amount or extent
         but which do not materially detract from the value, or interfere with
         the use, of the Properties or otherwise materially impair the business
         operations being conducted or proposed to be conducted thereon, tenant
         leases, service marks and trade names used in connection with such
         Properties, ground leases and ownership by others of certain items of
         equipment and other items of personal property that are not material to
         the conduct of business operations at such Properties; (B) with respect
         to the Properties in which the Operating Partnership owns, directly or
         indirectly, less than all of the ownership interest (the "Joint Venture
         Properties"), the Operating Partnership or its subsidiaries have good
         and marketable title to such ownership interests and the respective
         entities owning the Joint Venture Properties have good and marketable
         title to such interests in the Joint Venture Properties and good and
         marketable title to the improvements thereon and all other assets that
         are required for the effective operation of such Properties in the
         manner in which they currently are operated, subject to the exceptions
         set forth in clause (A) above; (C) the ground leases under which the
         applicable subsidiaries of the Operating Partnership lease the land on
         which certain Properties are located are in full force and effect, and
         each of such subsidiaries is not in default in respect of any of the
         terms or provisions of such leases and neither the Operating
         Partnership nor any such subsidiary has not received notice of the
         assertion of any claim by anyone adverse to such subsidiaries' rights
         as lessees under such leases, or affecting or questioning such
         subsidiaries' right to the continued possession or use of the Property
         under such leases or of a default under such leases; (D) all liens,
         charges, encumbrances, claims, or restrictions on or affecting any of
         the Properties and the assets of the


                                       9

         Operating Partnership or any of its subsidiaries are disclosed in the
         Prospectus, subject to the exceptions set forth in clause (A) above;
         (E) neither any subsidiary of the Operating Partnership nor any tenant
         of any of the Properties is in default under any of the leases pursuant
         to which the Operating Partnership or any of its subsidiaries, as
         lessor, leases its Property (and the Operating Partnership does not
         know of any event which, but for the passage of time or the giving of
         notice, or both, would constitute a default under any of such leases)
         other than such defaults and unmatured events of default that would not
         result in a Material Adverse Effect; (F) except for such rights of
         first refusal as may be contained in the agreements related to the
         Joint Venture Properties, no person has an option or right of first
         refusal to purchase all or part of any Property or any interest
         therein; (G) each of the Properties complies with all applicable codes,
         laws and regulations (including, without limitation, building and
         zoning codes, laws and regulations and laws relating to access to the
         Properties), except if and to the extent disclosed in the Prospectus
         and except for such failures to comply that would not individually or
         in the aggregate result in a Material Adverse Effect; (H) there is in
         full force and effect insurance coverages for the assets of the
         Properties that are commercially reasonable for such types of assets,
         and neither the Operating Partnership nor any of its subsidiaries has
         received from any insurance company notice of any material defects or
         deficiencies affecting the insurability of any such assets (including
         the Properties); and (I) neither the Operating Partnership nor any of
         its subsidiaries has any knowledge of any pending or threatened
         condemnation proceedings, zoning change, or other similar proceeding or
         action that will in any manner affect the size of, use of, improvements
         on, construction on or access to the Properties, except such
         proceedings or actions as are disclosed in the Prospectus or that would
         not have a Material Adverse Effect.

         Prospectus or as would not have a Material Adverse Effect: (A) each
         Property, including, without limitation, the Environment (as defined

         Environmental Law applicable to such Property, and no condition exists
         on, in, under or, to the knowledge of the Operating Partnership or any
         of its subsidiaries adjacent to, any Property that could result in the
         incurrence of material liabilities or any material violations of any
         Environmental Law applicable to such Property, or give rise to the
         imposition of any Lien (as defined below) under any Environmental Law;

         and its subsidiaries do not constitute "plan assets" under the Employee
         Retirement Income Security Act of 1974, as amended, including the
         regulations and published interpretations thereof.

                  (xxviii) REGULATIONS G, T, U AND X. None of the transactions
         contemplated by this Agreement (including, without limitation, the use
         of the proceeds from the sale of the Securities) will violate or result
         in a violation of Section 7 of the 1934 Act, or any regulation
         promulgated thereunder, including, without limitation, Regulations G,
         T, U and X of the Board of Governors of the Federal Reserve System.

                  (xxix) PARTNERSHIP CLASSIFICATION. The Operating Partnership
         and each of the Significant Subsidiaries that are partnerships are
         properly classified as partnerships, and not as corporations or as
         associations taxable as corporations,


                                       12
<PAGE>


         for federal income tax purposes throughout the period from July 11,
         1997 through the date hereof, or, in the case of any Significant
         Subsidiary partnerships that have terminated, through the date of
         termination of such Significant Subsidiary partnerships.

                  (xxx) CROSS DEFAULTS. The mortgages and deeds of trust
         encumbering the properties and assets described in general in the
         Prospectus are not convertible and are not cross-defaulted or
         cross-collateralized to any property not owned by the Operating
         Partnership or any of its subsidiaries; and, except as disclosed in the
         Prospectus, neither the Operating Partnership nor any of its
         subsidiaries holds participating interests in such mortgages and deeds
         of trust.

         (b) Any certificate signed by any officer of the Company, on behalf of
the Operating Partnership, and delivered to the Representative or to counsel for
the Underwriters shall be deemed a representation and warranty by the Operating
Partnership to each Underwriter as to the matters covered thereby.

         SECTION 2. SALE AND DELIVERY; CLOSING.

         (a) SECURITIES. On the basis of the representations and warranties
herein contained and subject to the terms and conditions set forth herein, the
Operating Partnership agrees to sell to each Underwriter, severally and not
jointly, and each Underwriter, severally and not jointly, agrees to purchase
from the Operating Partnership, at the price set forth in Schedule B, the
aggregate principal amount of Securities set forth in Schedule A opposite the
name of such Underwriter, plus any additional principal amount of Securities
which such Underwriter may become obligated to purchase pursuant to the
provisions of Section 10 hereof.

         (b) PAYMENT. Payment of the purchase price for, and delivery of
certificates for, the Securities shall be made at the offices of Brown & Wood
LLP, One World Trade Center, New York, New York 10048-0557, or at such other
place as shall be agreed upon by the Representative and the Operating
Partnership, at 9:00 A.M. (New York City time) on the third business day after
the date hereof (unless postponed in accordance with the provisions of Section
10), or such other time not later than ten business days after such date as
shall be agreed upon by the Representative and the Operating Partnership (such
time and date of payment and delivery being herein called "Closing Time").

         Payment shall be made to the Operating Partnership by wire transfer of
immediately available funds to a bank account designated by the Operating
Partnership, against delivery to the Representative for the respective accounts
of the Underwriters of certificates for the Securities to be purchased by them.
It is understood that each Underwriter has authorized the Representative, for
its account, to accept delivery of, receipt for, and make payment of the
purchase price for, the Securities which it has agreed to purchase. J.P. Morgan,
individually and not as representative of the Underwriters, may (but shall not
be obligated to) make payment of the purchase price for the Securities to be
purchased by any Underwriter whose funds have not been received by the Closing
Time, but such payment shall not relieve such Underwriter from its obligations
hereunder.


                                       13
<PAGE>


         (c) DENOMINATIONS; REGISTRATION. The Securities shall be in book-entry
form only and shall be represented by global certificates in such denominations
and registered in such names as the Representative may request in writing at
least two full business days before the Closing Time. The Securities will be
made available for examination and packaging by the Representative in The City
of New York not later than 10:00 A.M. (New York City time) on the business day
prior to the Closing Time.

         SECTION 3. COVENANTS OF THE OPERATING PARTNERSHIP. The Operating
Partnership covenants with each Underwriter as follows:

         (a) COMPLIANCE WITH SECURITIES REGULATIONS AND COMMISSION REQUESTS.
During the period when the Prospectus is required by the 1933 Act to be
delivered in connection with sales of the Securities, the Operating Partnership
will notify the Representative immediately, and confirm the notice in writing,
(i) when any post-effective amendment to the Registration Statement shall become
effective, or any amendment or supplement to the Prospectus shall have been
filed, (ii) of the receipt of any comments from the Commission, (iii) of any
request by the Commission for any amendment to the Registration Statement or any
amendment or supplement to the Prospectus or for additional information, and
(iv) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus, or of the suspension of the
qualification of the Securities for offering or sale in any jurisdiction, or of
the initiation or threatening of any proceedings for any of such purposes. The
Operating Partnership will promptly effect the filings necessary pursuant to
Rule 424(b) and will take such steps as it deems necessary to ascertain promptly
whether the form of prospectus transmitted for filing under Rule 424(b) was
received for filing by the Commission and, in the event that it was not, it will
promptly file such prospectus. The Company will make every reasonable effort to
prevent the issuance of any stop order and, if any stop order is issued, to
obtain the lifting thereof at the earliest possible moment.

         (b) FILING OF AMENDMENTS. During the period when the Prospectus is
required by the 1933 Act to be delivered in connection with sales of the
Securities, the Operating Partnership will give the Representative notice of its
intention to file or prepare any amendment to the Registration Statement
(including any filing under Rule 462(b)) or any amendment, supplement or
revision to either the prospectus included in the Registration Statement at the
time it became effective or to the Prospectus, whether pursuant to the 1933 Act,
the 1934 Act or otherwise, will furnish the Representative with copies of any
such documents a reasonable amount of time prior to such proposed filing or use,
as the case may be, and will not file or use any such document to which the
Representative or counsel for the Underwriters shall object.

         (c) DELIVERY OF REGISTRATION STATEMENTS. The Operating Partnership has
furnished or will deliver to the Representative and counsel for the
Underwriters, without charge, conformed copies of the Registration Statement as
originally filed and of each amendment thereto (including exhibits filed
therewith or incorporated by reference therein) and conformed copies of all
consents and certificates of experts, and will also deliver to the
Representative, without charge, a conformed copy of the Registration Statement
as originally filed and of each amendment thereto (without exhibits) for each of
the Underwriters. The copies of the


                                       14
<PAGE>


Registration Statement and each amendment thereto furnished to the Underwriters
will be identical to the electronically transmitted copies thereof filed with
the Commission pursuant to EDGAR.

         (d) DELIVERY OF PROSPECTUSES. The Operating Partnership has delivered
to each Underwriter, without charge, as many copies of each preliminary
prospectus, if any, as such Underwriter reasonably requested, and the Operating
Partnership hereby consents to the use of such copies for purposes permitted by
the 1933 Act. The Operating Partnership will furnish to each Underwriter,
without charge, during the period when the Prospectus is required to be
delivered under the 1933 Act or the 1934 Act, such number of copies of the
Prospectus (as amended or supplemented) as such Underwriter may reasonably
request. The Prospectus and any amendments or supplements thereto furnished to
the Underwriters will be identical to the electronically transmitted copies
thereof filed with the Commission pursuant to EDGAR, except to the extent
permitted by Regulation S-T.

         (e) CONTINUED COMPLIANCE WITH SECURITIES LAWS. The Operating
Partnership will comply with the 1933 Act and the 1933 Act Regulations, the 1934
Act and the 1934 Act Regulations and the 1939 Act and the 1939 Act Regulations
so as to permit the completion of the distribution of the Securities as
contemplated in this Agreement and in the Prospectus. If at any time when a
prospectus is required by the 1933 Act to be delivered in connection with sales
of the Securities, any event shall occur or condition shall exist as a result of
which it is necessary, in the opinion of counsel for the Underwriters or for the
Operating Partnership, to amend the Registration Statement or amend or
supplement the Prospectus in order that the Prospectus will not include any
untrue statements of a material fact or omit to state a material fact necessary
in order to make the statements therein not misleading in the light of the
circumstances existing at the time it is delivered to a purchaser, or if it
shall be necessary, in the opinion of such counsel, at any such time to amend
the Registration Statement or amend or supplement the Prospectus in order to
comply with the requirements of the 1933 Act or the 1933 Act Regulations, the
Operating Partnership will promptly prepare and file with the Commission,
subject to Section 3(b), such amendment or supplement as may be necessary to
correct such statement or omission or to make the Registration Statement or the
Prospectus comply with such requirements, and the Operating Partnership will
furnish to the Underwriters such number of copies of such amendment or
supplement as the Underwriters may reasonably request.

         (f) STATE LAW. The Operating Partnership will use its best efforts, in
cooperation with the Underwriters, to qualify the Securities for offering and
sale under the applicable securities laws of such states and other
jurisdictions, including real estate syndication laws, as the Representative may
designate and to maintain such qualifications in effect for a period of not less
than one year from the later of the effective date of the Registration Statement
and any Rule 462(b) Registration Statement; provided, however, that the
Operating Partnership shall not be obligated to file any general consent to
service of process or to qualify as a foreign limited partnership or as a dealer
in securities in any jurisdiction in which it is not so qualified or to subject
itself to taxation in respect of doing business in any jurisdiction in which it
is not otherwise so subject. In each jurisdiction in which the Securities have
been so qualified, the Operating Partnership will file such statements and
reports as may be required by the laws of such jurisdiction to continue such
qualification in effect for a period of not less than one year from the
effective date of the Registration Statement and any Rule 462(b) Registration


                                       15
<PAGE>


Statement. The Operating Partnership will also supply the Underwriters with such
information as is necessary for the determination of the legality of the
Securities for investment under the laws of such jurisdictions as the
Underwriters may request.

         (g) RULE 158. The Operating Partnership will timely file such reports
pursuant to the 1934 Act as are necessary in order to make generally available
to its securityholders as soon as practicable an earnings statement for the
purposes of, and to provide the benefits contemplated by, the last paragraph of
Section 11(a) of the 1933 Act.

         (h) USE OF PROCEEDS. The Operating Partnership will use the net
proceeds received by it from the sale of the Securities in the manner specified
in the Prospectus under "Use of Proceeds."

         (i) REPORTING REQUIREMENTS. The Operating Partnership, during the
period when the Prospectus is required to be delivered under the 1933 Act or the
1934 Act, will file all documents required to be filed with the Commission
pursuant to the 1934 Act within the time periods required by the 1934 Act and
the 1934 Act Regulations.

         (j) DTC. The Operating Partnership shall use its reasonable best
efforts in cooperation with the Underwriters to permit the Securities to be
eligible for clearance and settlement through DTC.

         (k) RATINGS. The Operating Partnership will use its reasonable best
efforts to enable Standard & Poor's Ratings Services ("S&P") and Moody's
Investors Service, Inc. ("Moody's") to provide their respective credit ratings
of the Securities.

         (l) NOTIFICATION OF CERTAIN EVENTS. Prior to the Closing Time, the
Operating Partnership will notify the Representative in writing immediately if
any event occurs that renders any of the representations and warranties of the
Operating Partnership contained herein inaccurate or incomplete.

         SECTION 4. PAYMENT OF FEES AND EXPENSES.

         (a) EXPENSES. The Operating Partnership will pay all expenses incident
to the performance of its obligations under this Agreement, including (i) the
preparation and filing of the Registration Statement (including financial
statements and exhibits) as originally filed and of each amendment and
supplement thereto, (ii) the preparation and delivery to the Underwriters of
this Agreement, any Agreement among Underwriters, the Indenture, and such other
documents as may be required in connection with the offering, purchase, sale and
delivery of the Securities, including any global securities, (iii) the
preparation, issuance and delivery of the Securities, including any global
Securities, (iv) the fees and disbursements of the Operating Partnership's
counsel, accountants, and other advisors or agents (including transfer agents
and registrars), (v) the qualification of the Securities under state securities
laws and real estate syndication laws in accordance with the provisions of
Section 3(f) hereof, including filing fees and the reasonable fees and
disbursements of counsel for the Underwriters in connection therewith and in
connection with the preparation, printing and delivery of a blue sky memorandum
(the "Blue Sky Memorandum") and any amendment or supplement thereto, (vi) the
printing and delivery to the


                                       16
<PAGE>


Underwriters of copies of each preliminary prospectus and the Prospectus and any
amendments or supplements thereto, (vii) any fees charged by nationally
recognized statistical rating organizations for the rating of the Securities,
(viii) the fees and expenses of the Trustee, including the reasonable fees and
disbursements of counsel for the Trustee, in connection with the Indenture and
the Securities, (ix) all expenses and listing fees incurred in connection with
the clearance and settlement of the Securities through DTC and (x) all expenses
and listing fees incurred in connection with the application to obtain CUSIP
numbers for the Securities.

         (b) TERMINATION OF AGREEMENT. If this Agreement is terminated by the
Representative in accordance with the provisions of Section 5 hereof, the
Operating Partnership shall reimburse the Underwriters for all of their
out-of-pocket expenses, including the reasonable fees and disbursements of
counsel for the Underwriters.

         SECTION 5. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The several
obligations of the Underwriters hereunder are subject to the accuracy, as of the
date hereof and as of the Closing Time, of the representations and warranties of
the Operating Partnership contained in Section 1(a) hereof, to the performance
by the Operating Partnership of its covenants and other obligations hereunder,
and to the following further conditions:

         (a) EFFECTIVENESS OF REGISTRATION STATEMENT. The Registration
Statement, including any Rule 462(b) Registration Statement, has become
effective and at Closing Time no stop order suspending the effectiveness of the
Registration Statement shall have been issued under the 1933 Act or proceedings
therefor initiated or threatened by the Commission, and any request on the part
of the Commission for additional information shall have been complied with to
the reasonable satisfaction of counsel to the Underwriters.

         (b) (i) At the Closing Time, you shall have received the favorable
opinion, dated as of the Closing Time, of Hogan & Hartson L.L.P., counsel for
the Operating Partnership, in form and substance satisfactory to you, to the
effect set forth in Exhibit A hereto.

                  (ii) At the Closing Time, the Representative shall have
         received the favorable opinion, dated as of the Closing Time, of Brown
         & Wood LLP, counsel for the Underwriters, with respect to the matters
         set forth in Items (1) (as to formation, valid existence and good
         standing only), (3), (4), (5), (7), (8), (9) and (15) of EXHIBIT A
         hereto and a statement similar to the statement referred to in the last
         paragraph of EXHIBIT A hereto.

         In giving their opinions required by Section 5(b)(i) and (ii), each of
Hogan & Hartson L.L.P. and Brown & Wood LLP may rely, (A) as to all matters of
fact, upon certificates and written statements of officers and employees of and
accountants for each of the Operating Partnership or the Significant
Subsidiaries and (B) as to the qualification and good standing of each of the
Operating Partnership or the Significant Subsidiaries to do business in any
state or jurisdiction, upon certificates of appropriate government officials or
opinions of counsel in such jurisdictions, which opinions shall be in form and
substance reasonably satisfactory to counsel for the Underwriters.


                                       17
<PAGE>

         (c) At the Closing Time, there shall not have been, since the
respective dates as of which information is given in the Prospectus, any
Material Adverse Change, and you shall have received a certificate of the Chief
Executive Officer and the chief financial or chief accounting officer of the
Company, on behalf of the Operating Partnership, dated as of the Closing Time,
evidencing compliance with the provisions of this subsection (c), stating that
(i) there has been no Material Adverse Change, (ii) the representations and
warranties set forth in Section 1(a) hereof are accurate as though expressly
made at and as of the Closing Time, and (iii) the conditions precedent set forth
in this Section 5 have been satisfied or waived and (iv) no stop order
suspending the effectiveness of the Registration Statement has been issued and
no proceedings for that purpose have been instituted or are pending or, to such
officer's knowledge, are contemplated by the Commission.

         (d) At the time of execution of this Agreement, you shall have received
from Ernst & Young, LLP a letter dated such date, in form and substance
satisfactory to you, containing statements and information of the type
ordinarily included in accountants' "comfort letters" to underwriters with
respect to the financial statements and certain financial information contained

         (e) At the Closing Time, you shall have received from Ernst & Young LLP
a letter dated as of the Closing Time to the effect that they reaffirm the

such letter.

         (f) At the Closing Time, counsel for the Underwriters shall have been

and all proceedings taken by the Operating Partnership in connection with the
issuance of the Securities as herein contemplated shall be satisfactory in form
and substance to you and counsel for the Underwriters.

         (g) At or prior to the Closing Time, the Securities shall be rated at
least Baa1 by Moody's and BBB+ by S&P and the Operating Partnership shall have
delivered to the Representative evidence reasonably satisfactory to the
Representative confirming that the Securities have such ratings; and since the
date of the Agreement, there shall not have occurred a downgrading in the rating
assigned to the Securities or any of the Operating Partnership's other debt
securities or the Company's preferred shares of beneficial interest by any
"nationally recognized statistical rating organization," as that term is defined
by the Commission for purposes of Rule 436(g)(2) under the 1933 Act, and no such
securities rating organization shall have publicly announced that it has under
surveillance or review any rating of the Securities or any of the Operating
Partnership's other debt securities or the Company's preferred shares of
beneficial interest.

         (h) If any condition specified in this Section 5 shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be terminated
by you by notice to the Operating Partnership at any time at or prior to the
Closing Time, and such termination shall be


                                       18
<PAGE>


without liability of any party to any other party except as provided in Sections
4 and except that Sections 6, 7, 8 and 13 shall survive any such termination and
remain in full force and effect.

         SECTION 6. INDEMNIFICATION.

         (a) INDEMNIFICATION OF UNDERWRITERS. The Operating Partnership agrees
to indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act, and any director, officer, employee or affiliate
thereof, as follows:

                  (i) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact contained in the
         Registration Statement (or any amendment thereto), or the omission or
         alleged omission therefrom of a material fact required to be stated
         therein or necessary to make the statements therein not misleading or
         arising out of any untrue statement or alleged untrue statement of a
         material fact contained in the Prospectus (or any amendment or
         supplement thereto), or the omission or alleged omission therefrom of a
         material fact necessary in order to make the statements therein, in the
         light of the circumstances under which they were made, not misleading;

                  (ii) against any and all loss, liability, claim, damage and
         expense whatsoever, as incurred, to the extent of the aggregate amount
         paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or of any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission; provided
         that (subject to Section 6(d) below) any such settlement is effected
         with the written consent of the Operating Partnership; and

                  (iii) against any and all expense whatsoever (including,
         without limitation, the reasonable fees and disbursements of counsel
         chosen by the Representative), reasonably incurred in investigating,
         preparing or defending against any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or threatened,
         or any claim whatsoever based upon any such untrue statement or
         omission, or any such alleged untrue statement or omission, to the
         extent that any such expense is not paid under (i) or (ii) above;

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Operating
Partnership by any Underwriter through the Representative expressly for use in
the Registration Statement (or any amendment thereto), or any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto).

         (b) INDEMNIFICATION OF THE OPERATING PARTNERSHIP. Each Underwriter,
severally and not jointly, agrees to indemnify and hold harmless the Operating
Partnership, and each


                                       19
<PAGE>


person, if any, who controls the Operating Partnership within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any trustee,
officer, employee or affiliate thereof, against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection (a)
of this Section 6, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto) or any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with written information concerning such Underwriter furnished to the
Operating Partnership through the Representative by or on behalf of such
Underwriter expressly for use in the Registration Statement (or any amendment
thereto) or such preliminary prospectus or the Prospectus (or any amendment or
supplement thereto).

         (c) ACTIONS AGAINST PARTIES; NOTIFICATION. Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement. In the case of parties indemnified pursuant to Section 6(a) above,
counsel to the indemnified parties shall be selected by the Representative, and,
in the case of parties indemnified pursuant to Section 6(b) above, counsel to
the indemnified parties shall be selected by the Operating Partnership. An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) also be counsel to the
indemnified party. In no event shall the indemnifying parties be liable for fees
and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances. No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 6 or Section 7 hereof (whether or not the indemnified parties are actual
or potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

         (d) SETTLEMENT WITHOUT CONSENT IF FAILURE TO REIMBURSE. If at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(iii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.


                                       20

         SECTION 7. CONTRIBUTION. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 hereof is for any reason held to be unenforceable by the indemnified
parties although applicable in accordance with its terms, the Operating
Partnership, on the one hand, and the Underwriters, on the other, shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by said indemnity agreement incurred by the Operating
Partnership and the Underwriters, as incurred, in such proportions that the
Underwriters are responsible for that portion represented by the percentage that
the discounts and commissions appearing on the cover page of the Prospectus
bears to the price to investors appearing thereon and the Operating Partnership
is responsible for the balance; provided, however, that no person guilty of
fraudulent misrepresentation (within the meaning of section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

         For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each trustee of the Company, and each person, if any, who controls the Operating
Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as the Operating
Partnership. The Underwriters' respective obligations to contribute pursuant to
this Section 7 are several in proportion to the principal amount of Securities
set forth opposite their respective names in Schedule A hereto and not joint.

         Notwithstanding the provisions of this Section 7, no Underwriter shall
be required to contribute any amount in excess of the amount by which the total
price at which the Securities purchased and sold by it to purchasers exceeds the
amount of any damages which such Underwriter has otherwise been required to pay
by reason of any untrue or alleged untrue statement or omission or alleged
omission in the Prospectus.

         SECTION 8. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE
DELIVERY. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company, on behalf of the
Operating Partnership, submitted pursuant hereto, shall remain operative and in
full force and effect, regardless of any investigation made by or on behalf of
any Underwriters or any controlling person, or by or on behalf of the Operating
Partnership or any controlling person, and shall survive delivery of the
Securities to the Underwriters.

         SECTION 9. TERMINATION OF AGREEMENT.

         (a) The Representative may terminate this Agreement, by notice to the
Operating Partnership, at any time at or prior to the Closing Time, (i) if there
has been, since the date of this Agreement or since the respective dates as of
which information is given in the Prospectus, any Material Adverse Change, (ii)
if there has occurred any material adverse change in the financial markets in
the United States or any outbreak of hostilities or escalation thereof or other
calamity or crisis or any change or development involving a prospective change
in national or international political, financial, or economic conditions, in
each case, the effect of which is such as to make it, in the Representative's
reasonable judgment, impracticable to market the


                                       21
<PAGE>


Securities or enforce contracts for the sale of the Securities, (iii) if trading
in any of the Company's shares of beneficial interest or the Operating
Partnership's debt securities has been suspended by the Commission or the New
York Stock Exchange, or if trading generally on the New York Stock Exchange, the
American Stock Exchange or the Nasdaq Stock Market has been suspended, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices have been required, by either of said exchanges or by such system or by
order of the Commission, the National Association of Securities Dealers, Inc.,
or any other governmental authority, or (iv) if a banking moratorium has been
declared by either federal, New York, Delaware or Maryland authorities.

         (b) If this Agreement is terminated pursuant to this Section 9, such
termination shall be without liability of any party to any other party except as
provided in Sections 4 and 10 hereof and provided further that Sections 4, 6, 7,
8 and 13 hereof shall survive such termination and remain in full force and
effect.

         Section 10. DEFAULT BY ONE OR MORE OF THE UNDERWRITERS. If one or more
of the Underwriters shall fail at the Closing Time to purchase the Securities
which it or they are obligated to purchase under this Agreement (the "Defaulted
Securities"), the Representative shall have the right, within 24 hours
thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the Representative shall not have completed
such arrangements within such 24-hour period, then:

         (a) if the aggregate principal amount of Defaulted Securities does not
exceed 10% of the aggregate principal amount of the Securities to be purchased
hereunder, the non-defaulting Underwriters shall be obligated, severally and not
jointly, to purchase the full amount thereof in the proportions that their
respective purchase obligations hereunder bear to the purchase obligations of
all non-defaulting Underwriters.

         (b) if the aggregate principal amount of Defaulted Securities exceeds
10% of the aggregate principal amount of the Securities to be purchased
hereunder, this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter.

         No action taken pursuant to this Section 10 shall relieve any
defaulting Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a termination
of this Agreement, either the Representative or the Operating Partnership shall
have the right to postpone the Closing Time for a period not exceeding seven
days in order to effect any required changes in the Registration Statement or
Prospectus or in any other documents or arrangements. As used herein, the term "
Underwriter" includes any person substituted for an Underwriter under this
Section 10.

                                    EXHIBIT A

                        Opinion of Hogan & Hartson L.L.P.


         (1) The Operating Partnership is a limited partnership formed and
validly existing and in good standing under the laws of the State of Delaware
and has the partnership power and partnership authority under the limited
partnership agreement of the Operating Partnership (the "Partnership Agreement")
and the Delaware Revised Uniform Limited Partnership Act (the "Delaware Act") to
own, lease and operate its current properties, to conduct the business in which
it is engaged or proposes to engage as described in the Prospectus and to enter
into and perform its obligations under the Underwriting Agreement and the
Indenture (collectively, the "Listed Agreements"), and the Securities. The
Operating Partnership is qualified or registered as a foreign limited
partnership and is in good standing under the laws of the States listed on
APPENDIX A hereto as of the respective dates of the certificates received from
such States. The Company is the managing general partner of the Operating
Partnership. As of March 20, 2000 there were ___ Units outstanding and the
Company held of record _______ Units, as reflected in the Partnership Agreement.

         (2) All of the outstanding units of partnership interest ("Units") of
the Operating Partnership have been duly authorized for issuance by the
Operating Partnership to the holders thereof, and assuming receipt of the
capital contributions specified in the Partnership Agreement, are validly issued
and fully paid.

         (3) The Securities have been duly authorized by the Operating
Partnership. The Securities, when issued and authenticated in the manner
provided for in the Indenture and delivered against payment in accordance with
the Underwriting Agreement, will be entitled to the benefits of the Indenture,
and will constitute valid and legally binding obligations of the Operating
Partnership, enforceable against the Operating Partnership in accordance with
their terms, except as the enforcement thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors' rights
(including, without limitation, the effect of statutory and other law regarding
fraudulent conveyances, fraudulent transfers and preferential transfers) and as
may be limited by the exercise of judicial discretion and the application of
principles of equity, including, without limitation, requirements of good faith,
fair dealing, conscionability and materiality (regardless of whether enforcement
is considered in a proceeding at law or in equity).

         (4) The Underwriting Agreement has been duly authorized, executed and
delivered by the Operating Partnership.

         (5) The Indenture has been duly authorized, executed and delivered by
the Operating Partnership and (assuming due authorization,


                                      A-1
<PAGE>


execution and delivery thereof by the other parties thereto) constitutes a valid
and binding agreement of the Operating Partnership, enforceable against the
Operating Partnership in accordance with its terms, except as may be limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights (including, without limitation, the effect of statutory and
other law regarding fraudulent conveyances, fraudulent transfers and
preferential transfers) and as may be limited by the exercise of judicial
discretion and the application of principles of equity, including, without
limitation, requirements of good faith, fair dealing, conscionability and
materiality (regardless of whether such agreement is considered in a proceeding
at law or in equity) and except that a waiver of rights under any usury law may
be unenforceable.

         (6) The Merger Agreement has been duly authorized, executed and
delivered by, and is a valid and binding agreement of, each of the Company and
the Operating Partnership, enforceable against each of the Company and the
Operating Partnership in accordance with its terms, except as may be limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights (including, without limitation, the effect of statutory and
other law regarding fraudulent conveyances, fraudulent transfers and
preferential transfers) and as may be limited by the exercise of judicial
discretion and the application of principles of equity, including, without
limitation, requirements of good faith, fair dealing, conscionability and
materiality (regardless of whether such agreement is considered in a proceeding
at law or in equity) and except that a waiver of rights under any usury law may
be unenforceable.

         (7) The Indenture has been duly qualified under the 1939 Act.

         (8) The Securities and the Indenture conform in all material respects
to the descriptions thereof contained in the Prospectus.

         (9) The Registration Statement, including any Rule 462(b) Registration
Statement, has been declared effective under the 1933 Act; any required filing
of the Prospectus pursuant to Rule 424(b) has been made in the manner and within
the time period required by Rule 424(b); and, to the best of such counsel's
knowledge, no stop order suspending the effectiveness of the Registration
Statement or any Rule 462(b) Registration Statement has been issued under the
1933 Act and no proceedings for that purpose have been instituted or are pending
or threatened by the Commission.

         (10) The execution, delivery and performance as of the date hereof by
the Operating Partnership of the Listed Agreements and the issuance and sale of
the Securities do not (i) violate the Delaware Act or the Partnership Agreement,
(ii) to such counsel's knowledge, violate any applicable law, rule, regulation,
order, judgment or decree of any Delaware agency or court, or (iii) breach or
constitute a default under any agreement or contract listed on APPENDIX B
hereto.


                                      A-2
<PAGE>


         (11) The Registration Statement, including any Rule 462(b) Registration
Statement, and the Prospectus, excluding the documents incorporated by reference
therein, and each amendment or supplement to the Registration Statement and
Prospectus, excluding the documents incorporated by reference therein, as of
their respective effective or issue dates (other than the financial statements
and supporting schedules included therein or omitted therefrom, and the
Trustee's Statement of Eligibility on Form T-1 (the "Form T-1"), as to which
such counsel need express no opinion), complied as to form in all material
respects with the requirements of the 1933 Act and the 1933 Act Regulations.

         (12) The documents incorporated by reference in the Registration
Statement and the Prospectus (other than the financial statements and supporting
schedules included therein or omitted therefrom, as to which such counsel need
express no opinion), when they became effective or were filed with the
Commission , as the case may be, complied as to form in all material respects
with the requirements of the 1933 Act or the 1934 Act, as applicable, and the
rules and regulations of the Commission thereunder.

         (13) Neither the Operating Partnership nor any Significant Subsidiary
is or after giving effect to the issuance of the Securities and the application
of the net proceeds therefrom as described in the Prospectus will be, as of the
date hereof, an "investment company" within the meaning of the 1940 Act.

         (14) No consent, approval, authorization or order of, or filing or
registration with, the Commission or any Delaware court or governmental agency
or body is required to be obtained or made by the Operating Partnership for the
issuance of the Securities or the performance as of the date hereof of the
obligations contained in the Securities and the Listed Agreements by the
Operating Partnership.

         (15) The information in the Prospectus under the captions "Description
of Notes," "Description of Debt Securities" and "Plan of Distribution" to the
extent that such information constitutes matters of law or legal conclusions,
has been reviewed by us and is correct in all material respects

         (16) The Operating Partnership is classified as a partnership, and is
not taxed as a corporation or association taxable as a corporation, for Federal
income tax purposes throughout the period from July 7, 1997 through the date
hereof.

         The opinions as to enforceability expressed in Paragraphs (3) and (5)
above shall be understood to mean only that if there is a default in performance
of an obligation, (i) if a failure to pay or other damage can be shown and (ii)
if the defaulting party can be brought into a court which will hear the case and
apply the governing law, then, subject to the availability of defenses, and to


                                      A-3
<PAGE>


the exceptions set forth in Paragraphs (3), (5) and (6) above, the court will
provide a money damage (or perhaps injunctive or specific performance) remedy.

         In giving its opinion required by Section 5(b)(i), such counsel shall
additionally state that no facts have come to their attention which cause such
counsel to believe that (i) the Registration Statement or any amendment thereto
(except for the Form T-1, as to which such counsel need make no statement), at
the time such Registration Statement or any such amendment became effective,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading or that the Prospectus or any amendment or supplement thereto
(except for the Form T-1, as to which such counsel need make no statement), at
the time the Prospectus was issued, at the time any such amended or supplemented
prospectus was issued or at the Closing Time, included or includes an untrue
statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, (ii) there are any
legal or governmental proceedings pending or threatened against the Operating
Partnership that are required to be disclosed in the Prospectus, other than
those disclosed therein, or (iii) there are any contracts or documents of a
character required to be described in the Prospectus that are not described or
referred to therein; provided that in making the foregoing statements (which
shall not constitute an opinion), such counsel need not express any views as to
the financial statements and supporting schedules and other financial
information and data included in or omitted from the Prospectus. In making the
foregoing statement, such counsel may state that such statement is based upon
such counsel's participation in conferences with officers and other
representatives of the Operating Partnership, representatives of the independent
public accountants for the Operating Partnership and with you and your
representatives during the course of the preparation of the Registration
Statement and the Prospectus.

                        EOP OPERATING LIMITED PARTNERSHIP

                              8.375% Notes due 2006

         This Note is one of a duly authorized issue of senior Notes of the
Issuer (hereinafter called the "Notes") of the series hereinafter specified, all
issued or to be issued under and pursuant to an Indenture dated as of September
2, 1997 (as amended, the "Indenture"), duly executed and delivered by the Issuer
to State Street Bank and Trust Company, as Trustee (herein called the "Trustee,"
which term includes any successor trustee under the Indenture with respect to
the series of Notes of which this Note is a part), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties, and immunities
thereunder of the Trustee, the Issuer, and the Holders of the Notes, and of the
terms upon which the Notes are, and are to be, authenticated and delivered. The
Notes may be issued in one or more series, which different series may be issued
in various aggregate principal amounts, may mature at different times, may bear
interest (if any) at different rates, may be subject to different redemption
provisions (if any), and may otherwise vary as provided in the Indenture. This
Note is one of a series designated as the 8.375% Notes due 2006 of the Issuer
(the "Notes"), limited in aggregate principal amount to $400,000,000, subject to
the provisions in the Indenture.

         In case an Event of Default with respect to the Notes shall have
occurred and be continuing, the principal hereof and Make-Whole Amount (if any)
may be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect, and subject to the conditions provided in the
Indenture.

         The Issuer may redeem this Note, at any time in whole or from time to
time in part, at the election of the Issuer, at a redemption price equal to the
sum of (i) the principal amount being redeemed plus accrued interest thereon to
the date fixed for redemption (the "Redemption Date") and (ii) the Make-Whole
Amount with respect hereto (the "Redemption Price"); provided, however, that
interest installments due on an Interest Payment Date which is on or prior to
the Redemption Date will be payable to the Holder hereof (or one or more
predecessor Notes) as of the close of business on the Record Date preceding such
Interest Payment Date. If notice has been given as provided in the Indenture and
funds for the redemption of this Note or any part thereof called for redemption
shall have been made available on the Redemption Date, this Note or such part
thereof will cease to bear interest on the Redemption Date referred to in such
notice and the only right of the Holder will be to receive payment of the
Redemption Price. Notice of any optional redemption of any Notes will be given
to the holder hereof (in accordance with the provisions of the Indenture), not
more than 60 nor less than 30 days prior to the Redemption Date. In the event of
redemption of this Note in part only, a new Note of like tenor for the
unredeemed portion hereof and otherwise having the same terms and provisions as
this Note shall be issued by the Issuer in the name of the Holder hereof upon
the presentation and surrender hereof.


                                       5

         The Indenture contains provisions for defeasance of (i) the entire
indebtedness of the Notes or (ii) certain covenants and Events of Default with
respect to the Notes, in each case upon compliance with certain conditions set
forth therein, which provisions apply to the Notes.

         The Indenture contains provisions permitting the Issuer and the
Trustee, with the consent of the Holders of not less than a majority of the
aggregate principal amount of the Notes at the time Outstanding of all series to
be affected (voting as one class), evidenced as provided in the Indenture, to
execute supplemental indentures adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of the Holders of
the Notes of each series; provided, however, that no such supplemental indenture
shall, without the consent of the Holder of each Note at the time Outstanding so
affected, (i) change the final maturity of any Note, or reduce the principal
amount thereof or any premium or Make-Whole Amount thereon, if any, or reduce
the rate or extend the time of payment of any interest thereon, or impair or
affect the rights of' any Holder to institute suit for the payment on any Note,
or (ii) reduce the percentage in principal amount of Outstanding Notes, the
Holders of which are required to consent to any such supplemental indenture, or
(iii) reduce the percentage in principal amount of Outstanding Notes, the
Holders of which are required to consent to any waiver of compliance with
certain provisions of the Indenture or any waiver of certain defaults
thereunder. It is also provided in the Indenture that, with respect to certain
defaults or Events of Default regarding the Notes of any series, the Holders of
a majority in aggregate principal amount Outstanding of the Notes of such series
(or, in the case of certain defaults or Events of Default, all series of Notes)
may on behalf of the Holders of all the Notes of such series (or all of the
Notes, as the case may be) waive any such past default or Event of Default and
its consequences, prior to any declaration accelerating the maturity of such
Notes, or, subject to certain conditions, may rescind a declaration of
acceleration and its consequences with respect to such Notes. The preceding
sentence shall not, however, apply to a default in or Event of Default relating
to the payment of the principal of or premium or Make-Whole Amount, if any, or
interest on any of the Notes or in respect of a covenant or provision contained
in the Indenture that cannot be modified or amended without the consent of the
Holders of each Note at the time Outstanding affected thereby. Any such consent
or waiver by the Holder of this Note (unless revoked as provided in the
Indenture) shall be conclusive and binding upon such Holder and upon all future
Holders and owners of this Note and any Notes that may be issued in exchange or
substitution herefor, irrespective of whether or not any notation thereof is
made upon this Note or such other Notes.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and any Make-Whole Amount
and interest on this Note in the manner, at the respective times, at the rate
and in the coin or currency herein prescribed.

         This Note is issuable only in registered form without coupons in
denominations of U.S. $1,000 and integral multiples thereof. Notes may be
exchanged for a like aggregate principal amount of Notes of this series of other
authorized denominations at the office or agency of the Issuer in Boston,

tax or other governmental charge imposed in connection therewith.

which term includes any successor trustee under the Indenture with respect to
the series of Notes of which this Note is a part), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties, and immunities
thereunder of the Trustee, the Issuer, and the Holders of the Notes, and of the
terms upon which the Notes are, and are to be, authenticated and delivered. The
Notes may be issued in one or more series, which different series may be issued
in various aggregate principal amounts, may mature at different times, may bear
interest (if any) at different rates, may be subject to different redemption
provisions (if any), and may otherwise vary as provided in the Indenture. This
Note is one of a series designated as the 8.375% Notes due 2006 of the Issuer
(the "Notes"), limited in aggregate principal amount to $100,000,000, subject to
the provisions in the Indenture.

         In case an Event of Default with respect to the Notes shall have
occurred and be continuing, the principal hereof and Make-Whole Amount (if any)
may be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect, and subject to the conditions provided in the
Indenture.

         The Issuer may redeem this Note, at any time in whole or from time to
time in part, at the election of the Issuer, at a redemption price equal to the
sum of (i) the principal amount being redeemed plus accrued interest thereon to
the date fixed for redemption (the "Redemption Date") and (ii) the Make-Whole
Amount with respect hereto (the "Redemption Price"); provided, however, that
interest installments due on an Interest Payment Date which is on or prior to
the Redemption Date will be payable to the Holder hereof (or one or more
predecessor Notes) as of the close of business on the Record Date preceding such
Interest Payment Date. If notice has been given as provided in the Indenture and
funds for the redemption of this Note or any part thereof called for redemption
shall have been made available on the Redemption Date, this Note or such part
thereof will cease to bear interest on the Redemption Date referred to in such
notice and the only right of the Holder will be to receive payment of the
Redemption Price. Notice of any optional redemption of any Notes will be given
to the holder hereof (in accordance with the provisions of the Indenture), not
more than 60 nor less than 30 days prior to the Redemption Date. In the event of
redemption of this Note in part only, a new Note of like tenor for the
unredeemed portion hereof and otherwise having the same terms and provisions as
this Note shall be issued by the Issuer in the name of the Holder hereof upon
the presentation and surrender hereof.


                                       5

         The Indenture contains provisions for defeasance of (i) the entire
indebtedness of the Notes or (ii) certain covenants and Events of Default with
respect to the Notes, in each case upon compliance with certain conditions set
forth therein, which provisions apply to the Notes.

         The Indenture contains provisions permitting the Issuer and the
Trustee, with the consent of the Holders of not less than a majority of the
aggregate principal amount of the Notes at the time Outstanding of all series to
be affected (voting as one class), evidenced as provided in the Indenture, to
execute supplemental indentures adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of the Holders of
the Notes of each series; provided, however, that no such supplemental indenture
shall, without the consent of the Holder of each Note at the time Outstanding so
affected, (i) change the final maturity of any Note, or reduce the principal
amount thereof or any premium or Make-Whole Amount thereon, if any, or reduce
the rate or extend the time of payment of any interest thereon, or impair or
affect the rights of' any Holder to institute suit for the payment on any Note,
or (ii) reduce the percentage in principal amount of Outstanding Notes, the
Holders of which are required to consent to any such supplemental indenture, or
(iii) reduce the percentage in principal amount of Outstanding Notes, the
Holders of which are required to consent to any waiver of compliance with
certain provisions of the Indenture or any waiver of certain defaults
thereunder. It is also provided in the Indenture that, with respect to certain
defaults or Events of Default regarding the Notes of any series, the Holders of
a majority in aggregate principal amount Outstanding of the Notes of such series
(or, in the case of certain defaults or Events of Default, all series of Notes)
may on behalf of the Holders of all the Notes of such series (or all of the
Notes, as the case may be) waive any such past default or Event of Default and
its consequences, prior to any declaration accelerating the maturity of such
Notes, or, subject to certain conditions, may rescind a declaration of
acceleration and its consequences with respect to such Notes. The preceding
sentence shall not, however, apply to a default in or Event of Default relating
to the payment of the principal of or premium or Make-Whole Amount, if any, or
interest on any of the Notes or in respect of a covenant or provision contained
in the Indenture that cannot be modified or amended without the consent of the
Holders of each Note at the time Outstanding affected thereby. Any such consent
or waiver by the Holder of this Note (unless revoked as provided in the
Indenture) shall be conclusive and binding upon such Holder and upon all future
Holders and owners of this Note and any Notes that may be issued in exchange or
substitution herefor, irrespective of whether or not any notation thereof is
made upon this Note or such other Notes.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and any Make-Whole Amount
and interest on this Note in the manner, at the respective times, at the rate
and in the coin or currency herein prescribed.

         This Note is issuable only in registered form without coupons in
denominations of U.S. $1,000 and integral multiples thereof. Notes may be
exchanged for a like aggregate principal amount of Notes of this series of other
authorized denominations at the office or agency of the Issuer in Boston,
Massachusetts, in the manner and subject to the limitations provided herein and
in the Indenture, but without the payment of any service charge except for any
tax or other governmental charge imposed in connection therewith.

otherwise, al such liability being expressly waived and released by the
acceptance hereof and as part of the consideration for the issue hereof.

Make-Whole Amount, if any, and subject to the provisions herein and on the face
hereof, interest hereon, and for all other purposes, and neither the Issuer nor

                  In our examination of the aforesaid documents, we have assumed
the genuineness of all signatures, the legal capacity of natural persons, the
accuracy and completeness of all documents submitted to us, the authenticity of
all original documents and the conformity to authentic original documents of all
documents submitted to us as copies (including telecopies). This opinion letter
is given, and all statements herein are made, in the context of the foregoing.

                  This opinion letter is based as to matters of law solely on
applicable provisions of (i) the Delaware Revised Uniform Limited Partnership
Act, as amended, (ii) Title 8 of the Corporations and Associations Article of
the Annotated Code of Maryland, as amended, and (iii) New York contract law (but
not including any laws, statutes, ordinances, administrative decisions, rules,
or regulations of any political subdivision of the State of New York), and we
express no opinion as to any other laws, statutes, ordinances, rules or
regulations (such as federal or state securities or "blue sky" laws).

                  Based upon, subject to and limited by the foregoing, we are of
the opinion that, assuming due authentication of the Notes by the Trustee and
the due execution and delivery of the Notes on behalf of the Partnership against
payment of the consideration for the Notes specified in the Underwriting
Agreement, the Notes constitute valid and binding obligations of the
Partnership, enforceable against the Partnership in accordance with their terms,
except as the enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights (including,
without limitation, the effect of statutory and other law regarding fraudulent
conveyances, fraudulent transfers and preferential transfers) and as may be
limited by the exercise of judicial discretion and the application of principles
of equity, including, without limitation, requirements of good faith, fair
dealing, conscionability and materiality (regardless of whether the Notes are
considered in a proceeding at law or in equity).

                  The opinion as to enforceability expressed above shall be
understood to mean only that if there is a default in performance of an
obligation, (i) if a failure to pay or other damage can be shown and (ii) if the
defaulting party can be brought into a court which will hear the case and apply
the governing law, then, subject to the availability of defenses, and to the
exceptions set forth above, the court will provide a money damage (or perhaps
injunctive or specific performance) remedy.

                  To the extent that the obligations of the Partnership under
the Indenture may be dependent upon such matters, we assume for purposes of this

opinion that the Trustee is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization; that the Trustee is
duly qualified to engage in the activities contemplated by the Indenture; that
the Indenture has been duly authorized, executed and delivered by the Trustee
and constitutes the valid and binding obligation of the Trustee enforceable
against the Trustee in accordance with its terms; that the Trustee is in
compliance, with respect to acting as a trustee under the Indenture, with all
applicable laws and regulations; and that the Trustee has the requisite
organizational and legal power and authority to perform its obligations under
the Indenture.

                  We assume no obligation to advise you of any changes in the
foregoing subsequent to the delivery of this opinion letter. This opinion letter
has been prepared solely in connection with the filing by the Partnership of a
Current Report on Form 8-K on the date hereof, which Form 8-K will be
incorporated by reference into the Registration Statement. This opinion letter
should not be quoted in whole or in part or otherwise be referred to, nor filed
with or furnished to any governmental agency or other person or entity, without
the prior written consent of this firm.

                  We hereby consent to the filing of this opinion letter as
Exhibit 5.1 to the above-described Form 8-K and to the reference to this firm
under the caption "Legal Matters" in the Prospectus and the Prospectus
Supplement. In giving this consent, we do not thereby admit that we are an
"expert" within the meaning of the Securities Act of 1933, as amended.

                                         Very truly yours,

                                         /s/ Hogan & Hartson L.L.P.
