Ladies and Gentlemen:

         Duke-Weeks Realty Corporation (the "Company," including its
predecessor, Duke Realty Investments, Inc.) may from time to time offer in one
or more series (i) shares of Common Stock, $.01 par value (the "Common Stock"),
(ii) shares of preferred stock, $.01 par value (the "Preferred Stock") and (iii)
shares of Preferred Stock represented by depositary shares (the "Depositary
Shares"), with an aggregate public offering price of up to $250,000,000 (or its
equivalent in another currency based on the exchange rate at the time of sale).
Duke-Weeks Realty Limited Partnership (the "Operating Partnership," including
its predecessor, Duke Realty Limited Partnership) may from time to time offer in
one or more series unsecured non-convertible investment grade debt securities
(the "Debt Securities"), with an aggregate public offering price of up to
$175,000,000 (or its equivalent in another currency based on the exchange rate
at the time of sale). The Common Stock, Preferred Stock, Depositary Shares and
Debt Securities (collectively, the "Securities") may be offered, separately or
together, in separate series, in amounts, at prices and on terms to be set forth
in one or more Prospectus Supplements as hereinafter defined. The Debt
Securities will be issued under one or more indentures, as amended or
supplemented (each, an "Indenture"), between the Operating Partnership and a
trustee (a "Trustee"). Each series of Debt Securities may vary, as applicable,
as to aggregate principal amount, maturity date, interest rate or formula and
timing of payments thereof, redemption or repayment provisions, and any other
variable terms which the Indenture contemplates may be set forth in the Debt
Securities as issued from time to time. As used herein, "the Representatives,"
unless the context otherwise requires, shall mean the parties to whom this
Agreement is addressed together with the other parties, if any, identified in
the applicable Terms Agreement (as hereinafter defined) as additional
co-managers with respect to Underwritten Securities (as hereinafter defined)
purchased pursuant thereto.

         Whenever the Company or the Operating Partnership determines to make an
offering of Securities through the Representatives or through an underwriting
syndicate managed by the Representatives, the Company or the Operating
Partnership, as the case may be, will enter into an agreement (the "Terms
Agreement") providing for the sale of such Securities (the "Underwritten
Securities") to, and the purchase and offering thereof by, the Representatives
and such other underwriters, if any, selected by the




Representatives as have authorized the Representatives to enter into such Terms
Agreement on their behalf (the "Underwriters," which term shall include the
Representatives whether acting alone in the sale of the Underwritten Securities
or as a member of an underwriting syndicate and any Underwriter substituted
pursuant to Section 10 hereof). The Terms Agreement relating to the offering of
Underwritten Securities shall specify the amount of Underwritten Securities to
be initially issued (the "Initial Securities"), the names of the Underwriters
participating in such offering (subject to substitution as provided in Section
10 hereof), the amount of Initial Securities which each such Underwriter
severally agrees to purchase, the names of such of the Representatives or such
other Underwriters acting as co-managers, if any, in connection with such
offering, the price at which the Initial Securities are to be purchased by the
Underwriters from the Company or the Operating Partnership, as the case may be,
the initial public offering price, if any, of the Initial Securities, the form,
time, date and place of delivery and payment, any delayed delivery arrangements
and any other variable terms of the Initial Securities (including, but not
limited to, current ratings, designations, liquidation preferences, voting and
other rights, denominations, interest rates or formulas, interest payment dates,
maturity dates and redemption or repayment provisions applicable to the Initial
Securities). In addition, each Terms Agreement shall specify whether the
Underwriters will be granted an option to purchase additional Underwritten
Securities to cover over-allotments, if any, and the aggregate amount of
Underwritten Securities subject to such option (the "Option Securities"). As
used herein, the term "Underwritten Securities" shall include the Initial
Securities and all or any portion of the Option Securities agreed to be
purchased by the Underwriters as provided herein, if any. The Terms Agreement,
which shall be substantially in the form of Exhibit A hereto, may take the form
of an exchange of any standard form of written telecommunication between the
Representatives and the Company or the Operating Partnership, as the case may
be. Each offering of Underwritten Securities through the Representatives or
through an underwriting syndicate managed by the Representatives will be
governed by this Agreement, as supplemented by the applicable Terms Agreement.

         The Company and the Operating Partnership have filed with the
Securities and Exchange Commission (the "Commission") a registration statement
on Form S-3 (No. 333-04695) for the registration of the Securities under the
Securities Act of 1933, as amended (the "1933 Act"), and the offering thereof
from time to time in accordance with Rule 430A or Rule 415 of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations"),
and the Company and the Operating Partnership have filed such amendments thereto
as may have been required prior to the execution of the applicable Terms
Agreement. Such registration statement (as amended, if applicable) has been
declared effective by the Commission and an Indenture has been qualified under
the Trust Indenture Act of 1939, as amended (the "1939 Act"). Such registration
statement and the prospectus constituting a part thereof (including in each case
the information, if any, deemed to be part thereof pursuant to Rule 430A(b) of
the 1933 Act Regulations), together with each prospectus supplement relating to
the offering of Underwritten Securities (the "Prospectus") pursuant to Rule 415
of the 1933 Act Regulations (each, a "Prospectus Supplement"), including all
documents incorporated therein by reference, as from time to time amended or
supplemented pursuant to the 1933 Act, the Securities Exchange Act of 1934, as
amended (the "1934 Act") or otherwise, are collectively referred to herein as
the "Registration Statement" and the "Prospectus," respectively; provided that
if any revised prospectus shall be provided to the Representatives by the
Company or the Operating Partnership for use in connection with the offering of
Securities which differs from the Prospectus on file at the Commission at the
time the Registration Statement becomes effective (whether or not such revised
prospectus is required to be filed by the Company or the Operating Partnership
pursuant to Rule 424(b) of the 1933 Act Regulations), the term "Prospectus"
shall refer to each such revised prospectus from and after the time it is first
provided to the Underwriters for such use; provided, further, that a Prospectus
Supplement shall be deemed to have supplemented the Prospectus only with respect
to the offering of Underwritten Securities to which it relates. Any registration
statement (including any supplement thereto or information which is deemed part
thereof) filed by the Company or the Operating Partnership under Rule 462(b) of
the 1933 Act


                                       2


Regulations (a "Rule 462(b) Registration Statement") shall be deemed to be part
of the Registration Statement. Any prospectus (including any amendment or
supplement thereto or information which is deemed part thereof) included in the
Rule 462(b) Registration Statement and any term sheet as contemplated by Rule
434 of the 1933 Act Regulations (a "Term Sheet") shall be deemed to be part of
the Prospectus. All references in this Agreement to financial statements and
schedules and other information which is "contained," "included" or "stated" in
the Registration Statement or the Prospectus (and all other references of like
import) shall be deemed to mean and include all such financial statements and
schedules and other information which is or is deemed to be incorporated by
reference in the Registration Statement or the Prospectus, as the case may be;
and all references in this Agreement to amendments or supplements to the
Registration Statement or the Prospectus shall be deemed to mean and include the
filing of any document under the 1934 Act which is or is deemed to be
incorporated by reference in the Registration Statement or the Prospectus, as
the case may be.

          The term "subsidiary" means a corporation or a partnership a majority
of the outstanding voting stock or partnership interests, as the case may be, of
which is owned or controlled, directly or indirectly, by the Company or the
Operating Partnership, as the case may be, or by one or more other subsidiaries
of the Company or the Operating Partnership.

          SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE
OPERATING PARTNERSHIP.

               (a)  The Company and the Operating Partnership represent and
warrant, jointly and severally, to the Representatives, as of the date hereof,
and to the Representatives and each other Underwriter named in the applicable
Terms Agreement, as of the date thereof, as of the Closing Time (as defined
below) and, if applicable, as of each Date of Delivery (as defined below) (in
each case, a "Representation Date"), as follows:

                    (i)       The Registration Statement and the Prospectus, at
          the time the Registration Statement became effective, complied, and as
          of each Representation Date will comply, in all material respects with
          the requirements of the 1933 Act, the 1933 Act Regulations and the
          1939 Act and the rules and regulations thereunder (the "1939 Act
          Regulations"). The Registration Statement, at the time the
          Registration Statement became effective, did not, and as of each
          Representation Date, 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.
          The Prospectus, as of the date hereof does not, and as of each
          Representation Date (unless the term "Prospectus" refers to a
          prospectus which has been provided to you by the Company or the
          Operating Partnership for use in connection with an offering of
          Securities which differs from the Prospectus on file at the Commission
          at the time the Registration Statement becomes effective, in which
          case at the time it is first provided to you for such use), Closing
          Time and Date of Delivery, if any, 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; provided,
          however, that 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 Company or the Operating Partnership in
          writing by any Underwriter through the Representatives expressly for
          use in the Registration Statement or Prospectus or to that part of the
          Registration Statement which shall constitute the Statement of
          Eligibility on Form T-1 under the 1939 Act (the "Statement of
          Eligibility") of a Trustee under an Indenture. If a Rule 462(b)
          Registration Statement is required in connection with the offering and
          sale of the Securities, the Company and the Operating Partnership have
          complied or will comply with the requirements of Rule 111 under the
          1933 Act Regulations relating to the payment of filing fees therefor.


                                       3


                    (ii)      Each preliminary prospectus, Prospectus,
          preliminary prospectus supplement and Prospectus Supplement 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, complied or will comply when so filed in all material respects
          with the 1933 Act and the 1933 Act Regulations thereunder.

                    (iii)     The documents incorporated or deemed to be
          incorporated by reference in the Registration Statement and the
          Prospectus pursuant to Item 12 of Form S-3 under the 1933 Act, at the
          time they were or hereafter are filed with the Commission, complied
          and will comply in all material respects with the requirements of the
          1934 Act and the rules and regulations of the Commission under the
          1934 Act (the "1934 Act Regulations"), and, when read together with
          the other information in the Prospectus, at the time the Registration
          Statement became effective and as of the applicable Representation
          Date or during the period specified in Section 3(f), did not and will
          not include 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, in the light of the circumstances under which they
          were made, not misleading.

                    (iv)      KPMG LLP, the accounting firm that audited the
          financial statements and supporting schedules included in, or
          incorporated by reference into, the Registration Statement and
          Prospectus, are independent public accountants as required by the 1933
          Act and the 1933 Act Regulations.

                    (v)       The financial statements included in, or
          incorporated by reference into, 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. Except as
          otherwise stated in the Registration Statement and Prospectus, said
          financial statements have been prepared in conformity with generally
          accepted accounting principles applied on a consistent basis
          throughout the periods involved. The supporting schedules included or
          incorporated by reference in the Registration Statement and the
          Prospectus present fairly the information required to be stated
          therein. The Company's ratios of earnings to fixed charges (actual
          and, if any, pro forma) included in the Prospectus under the caption
          "Selected Consolidated Financial Data" and in Exhibit 12 to the
          Registration Statement have been calculated in compliance with Item
          503(d) of Regulation S-K of the Commission. The financial information
          and data included in the Registration Statement and the Prospectus
          present fairly the information included therein and have been prepared
          on a basis consistent with that of the financial statements included
          or incorporated by reference in the Registration Statement and the
          Prospectus and the books and records of the respective entities
          presented therein. Pro forma financial information included in or
          incorporated by reference in the Registration Statement and the
          Prospectus has been prepared in accordance with the applicable
          requirements of the 1933 Act, the 1933 Act Regulations and guidelines
          of the American Institute of Certified Public Accountants with respect
          to pro forma financial information and includes all adjustments
          necessary to present fairly the pro forma financial position of the
          Operating Partnership and the Company, as applicable, at the
          respective dates indicated and the results of operations for the
          respective periods specified.

                    (vi)      No stop order suspending the effectiveness of the
          Registration Statement or any part thereof has been issued and no
          proceeding for that purpose has been instituted or is pending or, to
          the knowledge of the Company or the Operating Partnership, threatened
          by the Commission or by the state securities authority of any
          jurisdiction, and any request on the part of the Commission for
          additional information has been complied with. No order preventing or


                                       4


          suspending the use of the Prospectus has been issued and no proceeding
          for that purpose has been instituted or, to the knowledge of the
          Company or the Operating Partnership, threatened by the Commission or
          by the state securities authority of any jurisdiction.

                    (vii)     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, business affairs or business prospects of the Company, the
          Operating Partnership and any of their respective subsidiaries,
          whether or not arising in the ordinary course of business; (B) there
          has been no adverse change, material to the Duke Group (as hereinafter
          defined) as a whole, in the condition, financial or otherwise, or in

          the real properties owned, directly or indirectly, by the Company, the
          Operating Partnership or any subsidiary (the "Properties") or any
          entity wholly or partially owned by the Company, the Operating
          Partnership or any subsidiary which owns any Property (a "Property
          Partnership") (the Company, the Operating Partnership, the
          subsidiaries and the Property Partnerships are hereinafter jointly
          referred to as the "Duke Group"), whether or not arising in the
          ordinary course of business; (C) no material casualty loss or material
          condemnation or other material adverse event with respect to any
          Property has occurred; (D) there have been no transactions or

          obligation or liability, direct, contingent or otherwise which is
          material to the Duke Group as a whole; (F) there has been no material
          change in the short-term debt or long-term debt of the Duke Group as a
          whole; (G) except for regular quarterly dividends on the Common Stock
          and dividends on the Preferred Stock in amounts per share that are
          consistent with past practice, there has been no dividend or
          distribution of any kind declared, paid or made by the Company on any
          class of its capital stock; and (H) with the exception of transactions
          in connection with stock option and dividend reinvestment plans, the
          issuance of shares of Common Stock upon the exchange of partnership
          interests in the Operating Partnership ("Units") and the issuance of
          Units in connection with the acquisition of real or personal property,
          there has been no change in the capital stock or in the partnership
          interests, as the case may be, of the Company, the Operating
          Partnership or any subsidiary.

                    (viii)    Each of the Company and the Operating Partnership
          has been duly formed, and is validly existing and in good standing as
          a corporation or partnership under the laws of its jurisdiction of
          organization, with corporate or partnership power and authority to
          conduct the business in which it is engaged or proposes to engage and
          to own, lease and operate its properties as described in the
          Prospectus and to enter into and perform its obligations under this
          Agreement, the Terms Agreement and the Indenture.

                    (ix)      Each of the Company's and the Operating
          Partnership's subsidiaries has been duly formed, and is validly
          existing and in good standing as a corporation or partnership under
          the laws of its jurisdiction of organization, with corporate or
          partnership power and authority to conduct the business in which it is
          engaged or proposes to engage and to own, lease and operate its
          properties as described in the Prospectus.

                    (x)       Each of the Company, the Operating Partnership,
          their respective subsidiaries and the Property Partnerships is duly
          qualified or registered as a foreign partnership or corporation in
          good standing and authorized to do business in each jurisdiction in
          which such qualification is required whether by reason of the
          ownership or leasing of property or the conduct of business, except
          where the failure to so qualify would not have a material adverse
          effect on the


                                       5


          condition, financial or otherwise, or the earnings, assets, business
          affairs or business prospects of the Duke Group considered as a single
          enterprise (a "Material Adverse Effect").

                    (xi)      If the applicable Underwritten Securities are
          issued by the Company, and if the Prospectus contains the caption
          "Capitalization," the authorized, issued and outstanding shares of
          capital stock of the Company as of the date specified therein is as
          set forth in the column entitled "Historical" under such caption. All
          the issued and outstanding shares of capital stock of the Company have
          been duly authorized and are validly issued, fully paid and
          non-assessable and have been offered and sold in compliance with all
          applicable laws (including, without limitation, federal, state or
          foreign securities laws) and none of such shares of capital stock was
          issued in violation of preemptive or other similar rights of any
          security holder of the Company.

                    (xii)     If the applicable Underwritten Securities are
          issued by the Operating Partnership, and if the Prospectus contains
          the caption "Capitalization," the partner's equity of the Operating
          Partnership is as set forth in the column entitled "Historical" under
          such caption. All the issued and outstanding Units have been duly
          authorized and are validly issued, fully paid and non-assessable,
          except as provided under Indiana Code Section 23-16-7-8, and have been
          offered and sold or exchanged in compliance with all applicable laws
          (including, without limitation, federal, state or foreign securities
          laws).

                    (xiii)    All of the issued and outstanding shares of
          capital stock and partnership interests, as the case may be, of each
          subsidiary have been validly issued and fully paid and, other than the
          Property Partnerships, Duke-Weeks Realty Services Limited Partnership
          (the "Services Partnership") and Duke-Weeks Construction Limited
          Partnership (the "Construction Partnership"), are owned by the
          Company, the Operating Partnership or a subsidiary, in each case free
          and clear of any security interest, mortgage, pledge, lien,
          encumbrance, claim or equity. Neither the Company nor the Operating
          Partnership owns any direct or indirect equity interest in any entity
          other than the subsidiaries and the Property Partnerships, except for
          such interests as, in the aggregate, are not material to the
          condition, financial or otherwise, or the earnings, assets, business
          affairs or business prospects of the Duke Group considered as a single
          enterprise. Duke Services, Inc. is the sole general partner and a 1%
          owner of the Services Partnership, and the Operating Partnership and
          Duke Management, Inc. ("DMI") are the sole limited partners and 9% and
          90% owners, respectively, of the Services Partnership. The Services
          Partnership is the sole general partner and a 1% owner of the
          Construction Partnership. The 99% limited partnership interest of the
          Construction Partnership is owned by Duke Realty Construction, Inc.,
          an Indiana corporation which is owned 4.04% by the Services
          Partnership, 91.16% by the Operating Partnership and 4.8% by DMI.

                    (xiv)     Except for transactions described in the
          Prospectus and transactions in connection with dividend reinvestment
          plans, stock option and other employee benefit plans, a Rights
          Agreement, dated as of July 23, 1998, between the Company and American
          Stock Transfer & Trust Company (the "Rights Agreement"), the Company's
          outstanding 7.375% Series D Convertible Cumulative Redeemable
          Preferred Stock, the Operating Partnership's 7.375% Series D
          Convertible Cumulative Redeemable Preferred Units, the Operating
          Partnership's Series H Preferred Units and warrants dated as of July
          2, 1999 and registered as of the date hereof to Codina Group, Inc.,

                    (xv)      Each of the Property Partnerships has been duly
          formed as a partnership or a limited liability company, as the case
          may be, and is validly existing and in good standing as a partnership
          or limited liability company under the laws of its jurisdiction of
          organization and, if formed under the laws of a jurisdiction other
          than the State of Indiana, in good standing under the laws of such
          jurisdiction; each of the Property Partnerships has the requisite
          power and authority to own, lease and operate its properties, to
          conduct the business in which it is engaged and to enter into and
          perform its respective obligations under the agreements, to which it
          is a party. Each of the partnership or operating agreements, as the
          case may be, of the Property Partnerships is in full force and effect.

                    (xvi)     The applicable Underwritten Securities, if such
          Underwritten Securities are either Common Stock, Preferred Stock or
          Depositary Shares, have been duly authorized by the Company for
          issuance and sale to the Underwriters pursuant to this Agreement, and,
          when issued and delivered by the Company pursuant to this Agreement
          and the applicable Terms Agreement against payment of the
          consideration set forth in the Terms Agreement or any Delayed Delivery
          Contract (as defined in Section 2 hereof), will be validly issued,
          fully paid and non-assessable. Upon payment of the purchase price and
          delivery of such Underwritten Securities in accordance herewith, each
          of the Underwriters will receive good, valid and marketable title to
          such Underwritten Securities, free and clear of all security
          interests, mortgages, pledges, liens, encumbrances, claims and
          equities. The terms of such applicable Underwritten Securities conform
          to all statements and descriptions related thereto contained in the
          Prospectus. The form of stock or depositary certificate to be used to
          evidence the applicable Underwritten Securities will be in due and
          proper form and will comply with all applicable legal requirements.
          The issuance of such applicable Underwritten Securities is not subject
          to any preemptive or other similar rights.

                    (xvii)    The applicable Underwritten Securities, if such
          Underwritten Securities are Debt Securities, are in the form
          contemplated by the Indenture, have been duly authorized by the
          Operating Partnership for issuance and sale to the Underwriters
          pursuant to this Agreement and, when executed, authenticated, issued
          and delivered in the manner provided for in this Agreement, any Terms
          Agreement and the applicable Indenture, against payment of the
          consideration therefor specified in the applicable Terms Agreement or
          any Delayed Delivery Contract (as defined in Section 2 hereof), such
          Debt Securities will constitute valid and legally binding obligations
          of the Operating Partnership, entitled to the benefits of the
          Indenture and such Debt Securities will be enforceable against the
          Operating Partnership in accordance with their terms. Upon payment of
          the purchase price and delivery of such Underwritten Securities in
          accordance herewith, each of the Underwriters will receive good, valid
          and marketable title to such Underwritten Securities, free and clear
          of all security interests, mortgages, pledges, liens, encumbrances,
          claims and equities. The terms of such applicable Underwritten
          Securities conform to all statements and descriptions related thereto
          in the Prospectus. Such Underwritten Securities rank and will rank on
          a parity with all unsecured indebtedness (other than subordinated
          indebtedness) of the Operating Partnership that is outstanding on the
          Representation Date or that may be incurred thereafter, and senior to
          all subordinated indebtedness of the Operating Partnership that is
          outstanding on the Representation Date or that may be incurred
          thereafter, except that such Underwritten Securities will be
          effectively subordinated to the prior claims of each secured mortgage
          lender to any specific Property which secures such lender's mortgage.

                    (xviii)   If applicable, the Common Stock issuable upon
          conversion of any of the Preferred Stock (including Preferred Stock
          represented by Depositary Shares) will have been duly and validly
          authorized and reserved for issuance upon such conversion or exercise
          by all necessary action and such stock, when issued upon such
          conversion or exercise, will be duly and


                                       7


          validly issued, fully paid and non-assessable, and the issuance of
          such stock upon such conversion or exercise will not be subject to
          preemptive or other similar rights; the Common Stock so issuable
          conforms in all material respects to all statements relating thereto
          contained in the Prospectus.

                    (xix)     The Underwritten Securities being sold pursuant to
          the applicable Terms Agreement will conform in all material respects
          to the statements relating thereto contained in the Prospectus and
          will be in substantially the form filed or incorporated by reference,
          as the case may be, as an exhibit to the Registration Statement.

          or the documents incorporated by reference therein or to be filed as
          exhibits thereto which have not been so described and/or filed as
          required and the descriptions thereof or references thereto are
          correct in all material respects and no material defaults exist in the
          due performance or observance of any material obligation, agreement,
          covenant or condition contained in any such contract or document.

          in violation of its charter, by-laws, certificate of limited
          partnership or partnership agreement, as the case may be, or in
          default in the performance or observance of any obligation, agreement,
          covenant or condition contained in any contract, 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
          its property or assets is subject, which default separately or in the
          aggregate would have a Material Adverse Effect.

                    (xxii) (A)    This Agreement has been duly and validly
          authorized, executed and delivered by the Company and the Operating
          Partnership, and, assuming due authorization, execution and delivery
          by the Representatives, constitutes a valid and binding obligation of
          the Company and the Operating Partnership, enforceable in accordance
          with its terms, and (B) at the Representation Date, the Terms
          Agreement and the Delayed Delivery Contracts (as defined in Section 2
          hereof), if any, will have been duly and validly authorized, executed
          and delivered by the Company and the Operating Partnership, as the
          case may be, and, assuming due authorization, execution and delivery
          by the Representatives will be valid and binding agreements,
          enforceable in accordance with its or their terms.

                    (xxiii)   If applicable, the Indenture (A) has been duly
          qualified under the 1939 Act, has been duly and validly authorized,
          executed and delivered by the Operating Partnership, and when executed
          and delivered by the Trustee, will constitute a valid and binding
          obligation of the Operating Partnership, enforceable in accordance
          with its terms, and (B) conforms in all material respects to the
          description thereof in the Prospectus.

                    (xxiv)    Each of the partnership agreements to which any of
          the Company, the Operating Partnership or their respective
          subsidiaries is a party has been duly authorized, executed and
          delivered by such party and constitutes a valid and binding obligation
          thereof, enforceable in accordance with its terms.

                    (xxv)     The execution and delivery of this Agreement, the
          applicable Terms Agreement, any Indenture and any deposit agreement

          the obligations set forth herein or therein, and the consummation of
          the transactions contemplated hereby and thereby or in the Prospectus
          by the Company and the Operating Partnership, will not conflict with
          or constitute a breach or violation by the Company or

          the Operating Partnership of, or default under, or result in the
          creation or imposition of any lien, charge or encumbrance upon any
          Property or assets of the Duke Group pursuant to any contract,
          indenture, mortgage, loan agreement, note, lease, joint venture or
          partnership agreement or other instrument or agreement to which the
          Company, the Operating Partnership or any subsidiary is a party or by
          which they, either of them, any of their respective properties or
          other assets or any Property may be bound or subject which is material
          to the Duke Group as a whole; nor will such action conflict with or
          constitute a breach or violation by the Company or the Operating
          Partnership of, or default under, (A) the charter, by-laws,
          certificate of limited partnership or partnership agreement, as the
          case may be, of the Company, the Operating Partnership or any
          subsidiary or (B) to the extent it is material, any applicable law,
          rule, order, administrative regulation or administrative or court
          decree.

                    (xxvi)    No labor dispute with the employees of the Duke

          Partnership, is imminent; and neither the Company nor the Operating
          Partnership is aware of any existing or imminent labor disturbance by
          the employees of any of its principal suppliers, manufacturers or
          contractors which might be expected to have a Material Adverse Effect.

          required to be disclosed in the Registration Statement or the
          Prospectus (other than as disclosed therein), or that, if determined
          adversely to any entity belonging to the Duke Group or any Property,
          or any such officer or director, will or could reasonably be expected
          to result in any Material Adverse Effect, or which might materially
          and adversely affect the Properties or assets of the Duke Group or
          which might materially and adversely affect the consummation of this
          Agreement, the applicable Terms Agreement, the Indenture, if any, or

          affairs or business prospects of the Duke Group as a whole. There are
          no statutes or contracts or documents of the entities comprising the
          Duke Group which are required to be filed as exhibits to the

          which have not been so filed.

                    (xxviii)  No authorization, approval, consent or order of
          any court or governmental authority or agency is required that has not
          been obtained in connection with the consummation by the Company, the
          Operating Partnership or both, as the case may be, of the transactions
          contemplated by this Agreement, the applicable Terms Agreement, or the
          applicable Indenture, if any, except such as may be required under the
          1933 Act or the 1933 Act Regulations or the 1939 Act or the 1939 Act

                                       9


          operation will enable it to continue to meet the requirements for

          be conducted by it, and none of the entities comprising the Duke Group
          has received any notice of proceedings relating to the revocation or
          modification of any such certificate, authority or permit which,
          singly or in the aggregate, if the subject of an unfavorable decision,
          ruling or finding, would have a Material Adverse Effect.

          coverage as and when such coverage expires or to obtain similar
          coverage from similar insurers as may be necessary to continue its
          businesses at a cost that would not have a Material Adverse Effect,

          which have been required to be filed (except in any case in which the

          required to be paid and any other assessment, fine or penalty levied
          against it, to the extent that any of the foregoing is due and
          payable, except, in all cases, for any such tax, assessment, fine or
          penalty that is being contested in good faith.

               (b)  Any certificate signed by any officer of the Company, the
Operating Partnership or of any of their respective subsidiaries and delivered
to the Representatives or to counsel for the Underwriters shall be deemed a
representation and warranty by such entity to each Underwriter as to the matters
covered thereby.

        SECTION 2.  SALE AND DELIVERY TO UNDERWRITERS; CLOSING.

               (a)  The several commitments of the Underwriters to purchase the
Underwritten Securities pursuant to the applicable Terms Agreement shall be
deemed to have been made on the basis of the representations and warranties
herein contained and shall be subject to the terms and conditions set forth
herein or in the applicable Terms Agreement.

               (b)  In addition, on the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Company or the Operating Partnership, as the case may be, may grant,
if so provided in the applicable Terms Agreement relating to the Initial
Underwritten Securities, an option to the Underwriters named in such Terms
Agreement, severally and not jointly, to purchase up to the number of Option
Securities set forth therein at the same price per Option Security as is
applicable to the Initial Underwritten Securities, less an amount equal to any
dividends or distributions declared by the Company and paid or payable on the
Initial Underwritten Securities but not payable on the Option Securities. Such
option, if granted, will expire 30 days (or such lesser number of days as may be
specified in the applicable Terms Agreement) after the Representation Date
relating to the Initial Underwritten Securities, and may be exercised in whole
or in part from time to time only for the purpose of covering over-allotments
which may be made in connection with the offering and distribution of the
Initial Underwritten Securities upon notice by the Representatives to the
Company or the Operating Partnership, as the case may be, setting forth the
number of Option Securities as to which the several Underwriters are then
exercising the option and the time, date and place of payment and delivery for
such Option Securities. Any such time, date and place of delivery (a "Date of
Delivery") shall be determined by the Representatives, but shall not be later
than seven full business days nor earlier than two full business days after the
exercise of said option, nor in any event prior to the Closing Time, unless
otherwise agreed upon by the Representatives and the Company or the Operating
Partnership, as the case may be. If the option is exercised as to all or any
portion of the Option Securities, each of the Underwriters, acting severally and
not jointly, will purchase that proportion of the total number of Option


                                       13


Securities then being purchased which the number of Initial Underwritten
Securities each such Underwriter has severally agreed to purchase as set forth
in the applicable Terms Agreement bears to the total number of Initial
Underwritten Securities (except as otherwise provided in the applicable Terms
Agreement), subject to such adjustments as the Representatives in their
discretion shall make to eliminate any sales or purchases of fractional
Underwritten Securities.

               (c)  Payment of the purchase price for, and delivery of
certificates for, the Initial Underwritten Securities to be purchased by the
Underwriters shall be made at the offices of Rogers & Wells LLP, 200 Park
Avenue, New York, New York 10166, or at such other place as shall be agreed upon
by the Representatives and the Company or the Operating Partnership, as the case
may be, at 10:00 A.M. on the fourth business day (or the third business day if
required under Rule 15c6-1 of the 1934 Act, or unless postponed in accordance
with the provisions of Section 10) following the date of the applicable Terms
Agreement or at such other time as shall be agreed upon by the Representatives
and the Company (such time and date of payment and delivery being herein called
the "Closing Time"). In addition, in the event that any or all of the Option
Securities are purchased by the Underwriters, payment of the purchase price for,
and delivery of certificates for, such Option Securities shall be made at the
above-mentioned offices of Rogers & Wells LLP, or at such other place as shall
be agreed upon by the Representatives and the Company or the Operating
Partnership, as the case may be, on each Date of Delivery as specified in the
notice from the Representatives to the Company.

          Payment shall be made to the Company or the Operating Partnership, as
the case may be, by wire transfer of immediately available funds to a bank
account designated by the Company or the Operating Partnership, as the case may
be, against delivery to the Representatives for the respective accounts of the
Underwriters of the Underwritten Securities to be purchased by them.
Certificates for the Underwritten Securities and the Option Securities, if any,
shall be in such denominations and registered in such names as the
Representatives may request in writing at least two business days before the
Closing Time or the relevant Date of Delivery, as the case may be. It is
understood that each Underwriter has authorized the Representatives, for its
account, to accept delivery of, receipt for, and make payment of the purchase
price for, the Underwritten Securities and the Option Securities, if any, which
it has agreed to purchase. The Representatives, individually and not as
representatives of the Underwriters, may (but shall not be obligated to) make
payment of the purchase price for the Underwritten Securities or the Option
Securities, if any, to be purchased by any Underwriter whose funds have not been
received by the Closing Time or the relevant Date of Delivery, as the case may
be, but any such payment shall not relieve such Underwriter from its obligations
hereunder. The certificates for the Initial Securities and the Option
Securities, if any, will be made available for examination and packaging by the
Representatives not later than 10:00 A.M. on the last business day prior to the
Closing Time or the relevant Date of Delivery, as the case may be, in New York,
New York.

          If authorized by the applicable Terms Agreement, the Underwriters
named therein may solicit offers to purchase Underwritten Securities from the
Company or the Operating Partnership, as the case may be, pursuant to delayed
delivery contracts ("Delayed Delivery Contracts") substantially in the form of
Exhibit B hereto with such changes therein as the Company or the Operating
Partnership, as the case may be, may approve. As compensation for arranging
Delayed Delivery Contracts, the Company or the Operating Partnership, as the
case may be, will pay to the Representatives at Closing Time, for the respective
accounts of the Underwriters, a fee equal to that percentage of the amount of
Underwritten Securities for which Delayed Delivery contracts are made at the
applicable Closing Time as is specified in the applicable Terms Agreement. Any
Delayed Delivery Contracts are to be with institutional investors of the types
described in the Prospectus. At the applicable Closing Time, the Company or the
Operating Partnership, as the case may be, will enter into Delayed Delivery
Contracts (for not less than the minimum amount of Underwritten Securities per
Delayed Delivery Contract specified in the applicable Terms Agreement) with all
purchasers proposed by the Underwriters and previously approved by the Company


                                       14


or the Operating Partnership, as the case may be, as provided below, but not for
an aggregate principal amount of Underwritten Securities in excess of that
specified in the applicable Terms Agreement. The Underwriters will not have any
responsibility for the validity or performance of Delayed Delivery Contracts.

       The Representatives shall submit to the Company or the Operating
Partnership, as the case may be, at least three business days prior to the
applicable Closing Time, the names of any institutional investors with which it
is proposed that the Company or the Operating Partnership, as the case may be,
will enter into Delayed Delivery Contracts and the amount of Underwritten
Securities to be purchased by each of them, and the Company or the Operating
Partnership, as the case may be, will advise the Representatives at least two
business days prior to the applicable Closing Time, of the names of the
institutions with which the making of Delayed Delivery Contracts is approved by
the Company or the Operating Partnership, as the case may be, and the amount of
Underwritten Securities to be covered by each such Delayed Delivery Contract.

       The amount of Underwritten Securities agreed to be purchased by the
several Underwriters pursuant to the applicable Terms Agreement shall be reduced
by the amount of Underwritten Securities covered by Delayed Delivery Contracts,
as to each Underwriter as set forth in a written notice delivered by the
Representatives to the Company or the Operating Partnership, as the case may be;
provided, however, that the total amount of Underwritten Securities to be
purchased by all Underwriters shall be the total amount of Underwritten
Securities covered by the applicable Terms Agreement, less the amount of
Underwritten Securities covered by Delayed Delivery Contracts.

       SECTION 3.    COVENANTS OF THE COMPANY AND THE OPERATING PARTNERSHIP.
Each of the Company and the Operating Partnership covenants with the
Representatives, and with each Underwriter participating in the offering of
Underwritten Securities, as follows:

              (a)    In respect to each offering of Underwritten Securities, the
       Company or the Operating Partnership, as the case may be, will prepare a
       Prospectus Supplement setting forth the number of Underwritten Securities
       covered thereby and their terms not otherwise specified in the Prospectus
       pursuant to which the Underwritten Securities are being issued, the names
       of the Underwriters participating in the offering and the number of
       Underwritten Securities which each severally has agreed to purchase, the
       names of the Underwriters acting as co-managers in connection with the
       offering, the price at which the Underwritten Securities are to be
       purchased by the Underwriters from the Company or the Operating
       Partnership, as the case may be, the initial public offering price, if
       any, the selling concession and reallowance, if any, and such other
       information as the Representatives and the Company or the Operating
       Partnership, as the case may be, deem appropriate in connection with the
       offering of the Underwritten Securities; and the Company or the Operating
       Partnership, as the case may be, will promptly transmit copies of the
       Prospectus Supplement to the Commission for filing pursuant to Rule
       424(b) of the 1933 Act Regulations and will furnish to the Underwriters
       named therein as many copies of the Prospectus (including such Prospectus
       Supplement) as the Representatives shall reasonably request.

              (b)    If, at the time the Prospectus Supplement was filed with
       the Commission pursuant to Rule 424(b) of the 1933 Act Regulations, any
       information shall have been omitted therefrom in reliance upon Rule 430A
       of the 1933 Act Regulations, then immediately following the execution of
       the Terms Agreement, the Company and the Operating Partnership will
       prepare, and file or transmit for filing with the Commission in
       accordance with such Rule 430A and Rule 424(b) of the 1933 Act
       Regulations, a copy of an amended Prospectus, or, if required by such
       Rule 430A, a post-effective amendment to the Registration Statement
       (including amended Prospectuses), containing all information so omitted.
       If required, the Company and the Operating Partnership will prepare and
       file or transmit for filing a Rule 462(b) Registration Statement not


                                       15


       later than the date of execution of the Terms Agreement. If a Rule 462(b)
       Registration Statement is filed, the Company and the Operating
       Partnership shall make payment of, or arrange for payment of, the
       additional registration fee owing to the Commission required by Rule 111
       of the 1933 Act Regulations.

              (c)    The Company and the Operating Partnership will notify the
       Representatives immediately, and confirm such notice in writing, of (i)
       the effectiveness of any amendment to the Registration Statement, (ii)
       the transmittal to the Commission for filing of any Prospectus Supplement
       or other supplement or amendment to the Prospectus to be filed pursuant
       to the 1933 Act, (iii) the receipt of any comments from the Commission,
       (iv) 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 (v) the issuance by the Commission of any
       stop order suspending the effectiveness of the Registration Statement or
       the initiation of any proceedings for that purpose; and the Company and
       the Operating Partnership will make every reasonable effort to prevent
       the issuance of any such stop order and, if any stop order is issued, to
       obtain the lifting thereof at the earliest possible moment.

              (d)    At any time when the Prospectus is required to be delivered
       under the 1933 Act or the 1934 Act in connection with sales of the
       Underwritten Securities, the Company and the Operating Partnership will
       give the Representatives notice of its intention to file or prepare any
       amendment to the Registration Statement or any amendment or supplement to
       the Prospectus, whether pursuant to the 1933 Act, 1934 Act or otherwise,
       will furnish the Representatives with copies of any such amendment or
       supplement a reasonable amount of time prior to such proposed filing and,
       unless required by law, will not file or use any such amendment or
       supplement or other documents in a form to which the Representatives or
       counsel for the Underwriters shall reasonably object.

              (e)    The Company and the Operating Partnership will deliver to
       the Representatives as soon as possible as many signed copies of the
       Registration Statement as originally filed and of each amendment thereto
       (including exhibits filed therewith or incorporated by reference therein
       and documents incorporated by reference therein) as the Representatives
       may reasonably request and will also deliver to the Representatives as
       many conformed copies of the Registration Statement as originally filed
       and of each amendment thereto (including documents incorporated by
       reference into the Prospectus) as the Representatives may reasonably
       request.

              (f)    The Company and the Operating Partnership will furnish to
       each Underwriter, from time to time 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 for the purposes contemplated by the
       1933 Act or the 1934 Act or the respective applicable rules and
       regulations of the Commission thereunder.

              (g)    If any event shall occur as a result of which it is
       necessary, in the reasonable opinion of counsel for the Underwriters, to
       amend or supplement the Prospectus in order to make the Prospectus not
       misleading in the light of the circumstances existing at the time it is
       delivered to a purchaser, the Company and the Operating Partnership will
       forthwith amend or supplement the Prospectus (in form and substance
       reasonably satisfactory to counsel for the Underwriters) so that, as so
       amended or supplemented, the Prospectus 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 existing at the time it is delivered to a purchaser, not
       misleading, and the Company and the Operating Partnership will furnish to
       the Underwriters a reasonable number of copies of such amendment or
       supplement.


                                       16


              (h)    The Company and the Operating Partnership will endeavor, in
       cooperation with the Underwriters, to qualify the Underwritten Securities
       for offering and sale under the applicable securities laws and real
       estate syndication laws of such states and other jurisdictions as the
       Representatives may designate. In each jurisdiction in which the
       Underwritten Securities have been so qualified, the Company and 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 so long as may be required for the distribution of the
       Underwritten Securities.

              (i)    With respect to each sale of Underwritten Securities, the
       Company and the Operating Partnership will make generally available to
       its security holders as soon as practicable, but not later than 90 days
       after the close of the period covered thereby, an earnings statement (in
       form complying with the provisions of Rule 158 of the 1933 Act
       Regulations) covering a twelve-month period beginning not later than the
       first day of the Company's fiscal quarter next following the "effective
       date" (as defined in said Rule 158) of the Registration Statement.

              (j)    Each of the Company and the Operating Partnership will use
       the net proceeds received by it from the sale of the Underwritten
       Securities in the manner specified in the Prospectus under "Use of
       Proceeds."

              (k)    The Company and the Operating Partnership, if applicable,
       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 Sections 13, 14 or 15 of the 1934
       Act within the time periods required by the 1934 Act and the 1934 Act
       Regulations.

              (l)    The Company will file with the New York Stock Exchange all
       documents and notices required by the New York Stock Exchange of
       companies that have securities listed on such exchange and, unless
       otherwise agreed upon with respect to Preferred Stock, Depository Shares
       and Debt Securities, will use its best efforts to maintain the listing of
       any Underwritten Securities listed on the New York Stock Exchange.

              (m)    In respect to each offering of Debt Securities, the
       Operating Partnership will qualify an Indenture under the 1939 Act and
       will endeavor to have a Statement of Eligibility submitted on behalf of
       the Trustee.

              (n)    The Company and the Operating Partnership will take all
       reasonable action necessary to enable Standard & Poor's Corporation
       ("S&P"), Moody's Investors Service, Inc. ("Moody's") or any other
       nationally recognized statistical rating organization to provide their
       respective credit ratings of any Underwritten Securities, if applicable.

              (o)    INTENTIONALLY OMITTED

              (p)    If the Preferred Stock is convertible into Common Stock,
       the Company will reserve and keep available at all times, free of
       preemptive rights and other similar rights, a sufficient number of shares
       of Common Stock for the purpose of enabling the Company to satisfy any
       obligations to issue such Common Stock upon conversion of the Preferred
       Stock.

              (q)    If the Preferred Stock is convertible into Common Stock,
       the Company will use its best efforts to list the Common Stock on the New
       York Stock Exchange.

              (r)    The Company will use its best efforts to continue to meet
       the requirements to qualify as a "real estate investment trust" under the
       Code.


                                       17


              (s)    During the period from the Closing Time until five years
       after the Closing Time, the Company and the Operating Partnership will
       deliver to the Representatives, (i) promptly upon their becoming
       available, copies of all current, regular and periodic reports of the
       Company mailed to its stockholders or filed with any securities exchange
       or with the Commission or any governmental authority succeeding to any of
       the Commission's functions, and (ii) such other information concerning
       the Company and the Operating Partnership as the Representatives may
       reasonably request.

       SECTION 4.    PAYMENT OF EXPENSES. The Company and the Operating
Partnership will pay all expenses incident to the performance of its obligations
under this Agreement and the applicable Terms Agreement, including (i) the
printing and filing of the Registration Statement as originally filed and of
each amendment thereto; (ii) the cost of printing, or reproducing, and
distributing to the Underwriters copies of this Agreement and the applicable
Terms Agreement; (iii) the preparation, issuance and delivery of the
Underwritten Securities to the Underwriters, including capital duties, stamp
duties and stock transfer taxes, if any, payable upon issuance of any of the
Underwritten Securities, the sale of the Underwritten Securities to the

                     by the Company, pursuant to this Agreement and the
                     applicable Terms Agreement against payment of the
                     consideration set forth in the Terms Agreement or any
                     Delayed Delivery Contract, will be validly issued, fully
                     paid and non-assessable. Upon payment of the purchase price
                     and delivery of such Underwritten Securities in accordance

                     statements and descriptions related thereto contained in

                     preemptive or other similar rights.

                            (x)    The applicable Underwritten Securities, if

                     authorized by the Operating Partnership for issuance and
                     sale to the Underwriters pursuant to this Agreement and,
                     when executed, authenticated, issued and delivered in the
                     manner provided for in this Agreement, the applicable Terms
                     Agreement and the applicable Indenture, against payment of
                     the consideration therefor specified in the applicable
                     Terms Agreement or any Delayed Delivery Contract, such Debt
                     Securities will constitute valid and legally binding
                     obligations of the Operating Partnership entitled to the

                     enforceable against the Operating Partnership in accordance
                     with their terms, except as such enforceability may be (1)
                     limited by bankruptcy, insolvency, reorganization,
                     liquidation, moratorium or


                                       21


                     other similar laws affecting the rights and remedies of
                     creditors generally and (2) subject to general principles
                     of equity (regardless of whether such enforceability is
                     considered in a proceeding in equity or at law). Upon
                     payment of the purchase price and delivery of such
                     Underwritten Securities in accordance herewith, each of the
                     Underwriters will receive good, valid and marketable title
                     to such Underwritten Securities, which to such counsel's
                     knowledge, after due inquiry, are free and clear of all
                     security interests, mortgages, pledges, liens,
                     encumbrances, claims and equities. The terms of the
                     applicable Underwritten Securities conform to all
                     statements and descriptions related thereto in the
                     Prospectus. Such Underwritten Securities rank and will rank
                     on a parity with all unsecured indebtedness (other than
                     subordinated indebtedness of the Operating Partnership that
                     is outstanding on the Representation Date or that may be
                     incurred thereafter) and senior to all subordinated
                     indebtedness of the Operating Partnership that is
                     outstanding on the Representation Date or that may be
                     incurred thereafter, except that such Underwritten
                     Securities will be effectively subordinated to the prior
                     claims of each secured mortgage lender to any specific
                     Property which secures such lender's mortgage.

                            (xi)   If applicable, the Common Stock issuable upon
                     conversion of any of the Preferred Stock (including
                     Preferred Stock represented by Depositary Shares) will have
                     been duly and validly authorized and reserved for issuance
                     upon such conversion or exercise by all necessary action
                     and such stock, when issued upon such conversion or
                     exercise, will be duly and validly issued, fully paid and
                     non-assessable, and the issuance of such stock upon such
                     conversion or exercise will not be subject to preemptive or
                     other similar rights; the Common Stock so issuable conforms
                     in all material respects to all statements relating thereto
                     contained in the Prospectus.

              such counsel has participated in conferences with officers and
              other representatives of the Company or the Operating Partnership,
              as the case may be, and the independent public accountants for the
              Company or the Operating Partnership, as the case may be, at which
              the contents of the Registration Statement and the Prospectus and
              related matters were discussed and in the preparation of the
              Registration Statement and the Prospectus and, on the basis of the
              foregoing, nothing has come to their attention that would lead
              them to believe that either the Registration Statement or any
              amendment thereto (excluding the financial statements and
              financial schedules included or


                                       25


              incorporated by reference therein or the Statement of Eligibility,
              as to which such counsel need express no belief), at the time it
              became effective or at the time an Annual Report on Form 10-K was
              filed by the Company and the Operating Partnership with the
              Commission (whichever is later), or at the Representation Date,
              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 (excluding the
              financial statements or financial schedules included or
              incorporated by reference therein or the Statement of Eligibility,
              as to which such counsel need express no belief), at the
              Representation Date 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.

                     In giving their opinions, Bose McKinney & Evans LLP and
              Rogers & Wells LLP may rely upon, or assume the accuracy of, (A)
              as to all matters of fact, certificates and written statements of

       or in equity shall be pending or, to the knowledge of the Company or the
       Operating Partnership, threatened against any entity belonging to the
       Duke Group which would be required to be set forth in the Prospectus
       other than as set forth therein; (ii) there shall not have been, since
       the date of the applicable Terms Agreement or since the respective dates
       as of which information is given in the Registration Statement and the

       received a certificate of the President or a Vice President of the
       Company and the Operating Partnership and of the chief financial or chief
       accounting officer of each such entity, dated as of the Closing Time,
       evidencing compliance with the provisions of this subsection (c) and
       stating that the representations and warranties in Section 1 hereof are
       true and correct with the same force and effect as though expressly made
       at and as of Closing Time.

              (d)    At the time of the execution of the applicable Terms
       Agreement, the Representatives shall have received from KPMG LLP a letter
       dated such date, in form and substance satisfactory to the
       Representatives, to the effect that: (i) they are independent public
       accountants with respect to the Company and the Operating Partnership as
       required by the 1933 Act and the 1933 Act Regulations; (ii) it is their
       opinion that the financial statements and supporting schedules included
       in the Registration Statement, or incorporated by reference therein, and
       covered by their opinions therein comply as to form in all material
       respects with the applicable accounting requirements of the 1933 Act and
       the 1933 Act Regulations and the 1934


                                       26


       Act and the 1934 Act Regulations; (iii) based upon limited procedures set
       forth in detail in such letter, including a reading of the latest
       available interim financial statements of the Company and the Operating
       Partnership, a reading of the minute books of the Company and the
       Operating Partnership, inquiries of officials of the Company and the
       Operating Partnership responsible for financial and accounting matters
       and such other inquiries and procedures as may be specified in such
       letter, nothing has come to their attention which causes them to believe
       that (A) the unaudited financial statements of the Company and the
       Operating Partnership included in the Registration Statement, or
       incorporated by reference therein, do not comply as to form in all
       material respects with the applicable accounting requirements of the 1933
       Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act
       Regulations, or material modifications are required for them to be
       presented in conformity with generally accepted accounting principles,
       (B) the operating data and balance sheet data set forth in the Prospectus
       under the caption "Selected Consolidated Financial Data" were not
       determined on a basis substantially consistent with that used in
       determining the corresponding amounts in the audited financial statements
       included or incorporated by reference in the Registration Statement, (C)
       the pro forma financial information included or incorporated by reference
       in the Registration Statement was not determined on a basis substantially
       consistent with that of the audited financial statements included or
       incorporated by reference in the Registration Statement or (D) at a
       specified date not more than five days prior to the date of the
       applicable Terms Agreement, there has been any change in the capital
       stock or the number of partnership interests of the Company, the
       Operating Partnership or their subsidiaries, as the case may be, or any
       increase in the debt of the Company, the Operating Partnership or their
       subsidiaries or any decrease in the net assets of the Company, the
       Operating Partnership or their subsidiaries, as compared with the amounts
       shown in the most recent consolidated balance sheet of the Company, the
       Operating Partnership and their subsidiaries, included in the
       Registration Statement or incorporated by reference therein, or, during
       the period from the date of the most recent consolidated statement of
       operations included in the Registration Statement or incorporated by
       reference therein to a specified date not more than five days prior to
       the date of the applicable Terms Agreement, there were any decreases, as
       compared with the corresponding period in the preceding year, in
       revenues, net income or funds from operations of the Company, the
       Operating Partnership and their subsidiaries, except in all instances for
       changes, increases or decreases which the Registration Statement and the
       Prospectus disclose have occurred or may occur; and (iv) in addition to
       the audit referred to in their opinions and the limited procedures
       referred to in clause (iii) above, they have carried out certain
       specified procedures, not constituting an audit, with respect to certain
       amounts, percentages and financial information which are included in the
       Registration Statement and Prospectus and which are specified by the
       Representatives, and have found such amounts, percentages and financial
       information to be in agreement with the relevant accounting, financial
       and other records of the Company, the Operating Partnership and their
       subsidiaries identified in such letter.

              (e)    At Closing Time, the Representatives shall have received
       from KPMG LLP a letter, dated the Closing Time, to the effect that they
       reaffirm the statements made in the letter furnished pursuant to
       subsection (d) of this Section, except that the "specified date" referred
       to shall be a date not more than five days prior to Closing Time.

              (f)    At Closing Time, the Underwritten Securities, if such
       Underwritten Securities are Debt Securities, shall be rated investment
       grade by one or more nationally recognized statistical rating
       organizations and the Operating Partnership shall have delivered to the
       Representatives a letter, dated the Closing Time, from each such rating
       organization, or other evidence satisfactory to the Representatives,
       confirming that such Underwritten Securities have such ratings; and since
       the date of this Agreement, there shall not have occurred a downgrading
       in the rating assigned to


                                       27


       such Underwritten Securities or any of the Operating Partnership's other
       debt securities by any nationally recognized securities rating
       organization, and no such securities rating organization shall have
       publicly announced that it has under surveillance or review, with
       possible negative implications, its rating of such Underwritten
       Securities or any of the Operating Partnership's other debt securities.

              (g)    At Closing Time and at each Date of Delivery, if any,
       counsel for the Underwriters shall have been furnished with such
       documents and opinions as they may require for the purpose of enabling
       them to pass upon the issuance and sale of the applicable Underwritten
       Securities as contemplated herein, or in order to evidence the accuracy
       of any of the representations or warranties, or the fulfillment of any of
       the conditions, herein contained; and all proceedings taken by the
       Company or the Operating Partnership, as the case may be, in connection
       with the issuance and sale of the applicable Underwritten Securities as
       herein contemplated shall be reasonably satisfactory in form and
       substance to the Representatives and counsel for the Underwriters.

              (h)    INTENTIONALLY OMITTED

              (i)    In the event that the Underwriters exercise their option
       provided in Section 2(b) hereof to purchase all or any portion of the
       Option Securities, the representations and warranties of the Company and
       the Operating Partnership contained herein and the statements in any
       certificates furnished by the Company and the Operating Partnership
       hereunder shall be true and correct as of each Date of Delivery and, at
       the relevant Date of Delivery, the Representatives shall have received:

                     (1)    A certificate, dated such Date of Delivery, of the
              President or a Vice President of the Company and the Operating
              Partnership and of the chief financial or chief accounting officer
              of each such entity confirming that their respective certificates
              delivered at Closing Time pursuant to Section 5(c) hereof remain
              true and correct as of such Date of Delivery.

                     (2)    The favorable opinion of Bose McKinney & Evans LLP,
              counsel for the Company, the Operating Partnership and their
              respective subsidiaries, in form and substance satisfactory to
              counsel for the Underwriters, dated such Date of Delivery,
              relating to the Option Securities to be purchased on such Date of
              Delivery and otherwise to the same effect as the opinion required
              by Section 5(b)(1) hereof.

                     (3)    The favorable opinion of Rogers & Wells LLP, counsel
              for the Underwriters, dated such Date of Delivery, relating to the
              Option Securities to be purchased on such Date of Delivery and
              otherwise to the same effect as the opinion required by Section
              5(b)(2) hereof.

                     (4)    A letter from KPMG LLP, in form and substance
              satisfactory to the Representatives and dated such Date of
              Delivery, substantially the same in form and substance as the
              letter furnished to the Representatives pursuant to Section 5(e)
              hereof, except that the "specified date" in the letter furnished
              pursuant to this Section 5(i)(4) shall be a date not more than
              five days prior to such Date of Delivery.

              If any condition specified in this Section shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be terminated
by the Representatives by notice to the Company and the Operating Partnership,
at any time at or prior to Closing Time, and such termination shall be without
liability of any party to any other party except as provided in Section 4
hereof.

       SECTION 6. INDEMNIFICATION.


                                       28


              (a)    Each of the Company and the Operating Partnership agrees,
jointly and severally, 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 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 any preliminary
           prospectus, Prospectus, preliminary prospectus supplement or
           Prospectus Supplement (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;
           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 Company or the Operating
           Partnership by any Underwriter through Salomon expressly for use
           in the Registration Statement (or any amendment thereto) or any
           preliminary prospectus or the Prospectus (or any amendment or
           supplement thereto);

                  (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 for which
           indemnification is provided under subsection (i) above if such
           settlement is effected with the written consent of the
           indemnifying party; and

                  (iii)  against any and all expense whatsoever, as incurred
           (including, subject to Section 6(c) hereof, the fees and
           disbursements of counsel chosen by Salomon), 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 for which
           indemnification is provided under subsection (i) above, to the
           extent that any such expense is not paid under (i) or (ii) above.

              (b)    Each Underwriter severally agrees to indemnify and hold
harmless the Company and the Operating Partnership and each person, if any, who
controls the Company and the Operating Partnership within the meaning of Section
15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss,
liability, claim, damage and expense described in the indemnity contained in
subsection (a) of this Section, 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 furnished to the Company or the Operating
Partnership by such Underwriter through Salomon 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)    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 which it may have otherwise than on account of this indemnity
agreement. An indemnifying party may participate at its own expense in the
defense of any such action. If it so elects within a reasonable time after
receipt of such notice, an indemnifying party, jointly with any other
indemnifying parties receiving such notice, may assume the defense of such
action with counsel chosen by it and reasonably approved by the indemnified
parties defendant in such action; PROVIDED, HOWEVER, that if the defendants in
any such action include both the indemnified party and the


                                       29


indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or parties
and such indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or parties. If
an indemnifying party assumes the defense of such action, the indemnifying
parties shall not be liable for any fees and expenses of counsel for the
indemnified parties incurred thereafter in connection with such action, unless
(i) the indemnified party shall have employed separate counsel in accordance
with the proviso to the next preceding sentence (it being understood, however,
that in connection with such action the indemnifying party shall not be liable
for the expenses of more than one separate counsel) (in addition to local
counsel) in any one action or separate but substantially similar actions in the
same jurisdiction arising out of the same general allegations or circumstances,
(ii) the indemnifying party does not promptly retain counsel reasonably
satisfactory to the indemnified party or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense of
the indemnifying party. The indemnifying party will not be liable for the costs
and expenses of any settlement of such action effected by such indemnified party
without the consent of the indemnifying party. 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)    If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as required by this Section 6, such indemnifying party agrees that it
shall be liable for any settlement of the nature contemplated by Section
6(a)(ii) 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.

         SECTION 7. CONTRIBUTION. If the indemnification provided for in Section
6 hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Operating Partnership, on the one hand, and the Underwriters, on the other hand,
from the offering of the Underwritten Securities pursuant to the applicable
Terms Agreement or (ii) if the allocation provided by clause (i) is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and the Operating Partnership, on the one hand, and of the
Underwriters, on the other hand, in connection with the statements or omissions
which resulted in such losses, liabilities, claims, damages or expenses, as well
as any other relevant equitable considerations.

              The relative benefits received by the Company and the Operating
Partnership, on the one hand, and the Underwriters, on the other hand, in
connection with the offering of the Underwritten Securities pursuant to the
applicable Terms Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of such Underwritten
Securities (before deducting expenses) received by the Company and the total
underwriting discount received by the Underwriters, in


                                       30


each case as set forth on the cover of the Prospectus, or, if Rule 434 is used,
the corresponding location on the Term Sheet, bear to the aggregate initial
public offering price of such Underwritten Securities as set forth on such
cover.

              The relative fault of the Company and the Operating Partnership,
on the one hand, and the Underwriters, on the other hand, shall be determined by
reference to, among other things, whether any such untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the Operating
Partnership or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

              The Company, the Operating Partnership and the Underwriters agree
that it would not be just and equitable if contribution pursuant to this Section
7 were determined by pro rata allocation (even if the Underwriters were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to above in this
Section 7. The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
7 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party 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 or alleged untrue statement or omission or alleged omission.

              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 Underwritten Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.

              No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 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 director of the Company, each officer of the Company who signed the
Registration Statement, and each person, if any, who controls the Company or 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
Company or the Operating Partnership, as the case may be. The Underwriters'
respective obligations to contribute pursuant to this Section 7 are several in
proportion to the number of Initial Underwritten Securities set forth opposite
their respective names in the applicable Terms Agreement and not joint.

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

         SECTION 9. TERMINATION OF AGREEMENT.

              (a)    The Representatives may terminate the applicable Terms
Agreement, by notice to the Company, at any time at or prior to Closing Time (i)
if there has been, since the date of such Terms Agreement or since the
respective dates as of which information is given in the Prospectus, any
material


                                       31


adverse change, affecting the Duke Group as a whole, in the condition, financial
or otherwise, or in the earnings, assets, business affairs or business prospects
of any entity belonging to the Duke Group or of any Property, whether or not
arising in the ordinary course of business; or (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 condition, in each case the
effect of which is such as to make it, in judgement of the Representatives,
impracticable or inadvisable to (x) commence or continue the offering of
Underwritten Securities to the public, or (y) enforce contracts for the sale of
the Underwritten Securities; or (iii) if trading in the Common Stock has been
suspended by the Commission or if trading generally on either the New York Stock
Exchange or the American Stock Exchange has been suspended, or minimum or
maximum prices for trading have been fixed, or maximum ranges for prices for
securities have been required, by either of said Exchanges or by order of the
Commission or any other governmental authority, or if a banking moratorium has
been declared by either Federal, New York or Indiana authorities; (iv) if
Preferred Stock is being offered and the rating assigned by any nationally
recognized statistical rating organization to any preferred shares of the
Company as of the date of the applicable Terms Agreement shall have been lowered
since such date or if any such rating organization shall have publicly announced
that it has placed any preferred shares or debt securities of the Company on
what is commonly termed a "watch list" for possible downgrading; or (v) if the
rating assigned by any nationally recognized statistical rating organization to
any long-term debt securities of the Operating Partnership as of the date of the
applicable Terms Agreement shall have been lowered since such date or if any
such rating organization shall have publicly announced that it has placed any
long-term debt securities of the Operating Partnership on what is commonly
termed a "watch list" for possible downgrading. As used in this Section 9(a),
the term " Prospectus" means the Prospectus in the form first used to confirm
sales of the Underwritten Securities.

              (b)    In the event of any such termination, in respect to such
terminated Terms Agreement, (x) the covenants set forth in Section 3 with
respect to any offering of Underwritten Securities shall remain in effect so
long as any Underwriter owns any such Underwritten Securities purchased from the
Company or the Operating Partnership, as the case may be, pursuant to the
applicable Terms Agreement and (y) the covenant set forth in Section 3(i)
hereof, the provisions of Section 4 hereof, the indemnity and contribution
agreements set forth in Sections 6 and 7 hereof, and the provisions of Sections
8 and 13 hereof shall remain in effect.

         SECTION 10. DEFAULT BY ONE OR MORE OF THE UNDERWRITERS. If one or more
of the Underwriters shall fail at Closing Time to purchase the Underwritten
Securities which it or they are obligated to purchase under the applicable Terms
Agreement (the "Defaulted Securities"), the Representatives 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 Representatives shall not
have completed such arrangements within such 24-hour period, then:

              (a)    if the number of Defaulted Securities does not exceed 10%
       of the Underwritten Securities to be purchased pursuant to such Terms
       Agreement, each of the non-defaulting Underwriters named in such Terms
       Agreement shall be obligated, severally and not jointly, to purchase the
       full amount thereof in the proportions that their respective underwriting
       obligations hereunder bear to the underwriting obligations of all
       non-defaulting Underwriters, or

              (b)    if the number of Defaulted Securities exceeds 10% of the
       Underwritten Securities to be purchased pursuant to such Terms Agreement,
       the applicable Terms Agreement shall terminate without liability on the
       part of any non-defaulting Underwriter.

              No action taken pursuant to this Section shall relieve any
defaulting Underwriter from liability in respect of its default under this
Agreement and the applicable Terms Agreement.


                                       32


              In the event of any such default which does not result in a
termination of the applicable Terms Agreement, each of the Representatives or
the Company shall have the right to postpone Closing Time for a period not
exceeding seven days in order to effect any required changes in the Registration
Statement or the Prospectus or in any other documents or arrangements.

         SECTION 11. NOTICES. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or

merely of such purchase.

Agreement shall be governed by and construed in accordance with the laws of the
State of New York applicable to agreements made and to be performed in said
State. Specified times of day refer to New York City time.
