Ladies and Gentlemen:

          Duke Realty Investments, Inc. (the "Company") 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 $650,000,000 (or its equivalent in another currency 
based on the exchange rate at the time of sale).  Duke Realty Limited 
Partnership (the "Operating 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 
$350,000,000 (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

<PAGE>

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. 333-49911) 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 
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.

            (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 Peat Marwick 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

<PAGE>

     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 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 earnings, assets, business affairs or
     business prospects of any of 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 acquisitions entered into by the Duke Group,
     other than those arising in the ordinary course of business, which are
     material with respect to the Duke Group as a whole; (E) neither the
     Company, the Operating Partnership nor any of their respective subsidiaries
     has incurred any 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 

<PAGE>

     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 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 securityholder 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 Realty Services Limited Partnership (the "Services Partnership") and
     Duke 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 DMI Partnership 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 and 95.96% by DMI Partnership.

           (xiv)    Except for transactions described in the Prospectus and
     transactions in connection with dividend reinvestment plans, stock option
     and other employee benefit plans, and a Rights Agreement, dated as of July
     23, 1998, between the Company and American Stock Transfer & Trust Company
     (the "Rights Agreement"), there are no outstanding rights, warrants or
     options to acquire, or instruments convertible into or exchangeable for, or
     agreements or understandings with respect to the sale or issuance of, any
     shares of capital stock of or partnership or other equity interest in the
     Company, the Operating Partnership or any subsidiary except for the shares
     of Common Stock which may be issued in exchange for Units.

            (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

<PAGE>

     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
     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.

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

           (xxi)    None of the entities comprising the Duke Group is 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,

     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

     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 and the issuance
     of the Underwritten Securities, the performance of 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,

     Group as a whole and is required to be disclosed in the Registration
     Statement or the Prospectus (other than as disclosed therein), or that, if

     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 the
     transactions contemplated herein and therein.  There are no pending legal

     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

     security documents or other agreements encumbering or otherwise recorded

     knows of any event which, but for the passage of time or the giving of
     notice, or both, would constitute a default under any of such documents or
     agreements, other than such defaults that would not have a Material Adverse
     Effect; (E) no tenant under any of the leases, pursuant to which the
     Operating Partnership or any Property Partnership, as lessor, leases its
     Property, has an option or right of first refusal to purchase the premises

     Adverse Effect; (F) each of the Properties complies with all applicable
     codes, laws and regulations (including, without limitation, building and
     zoning codes, laws and regulations and laws relating to access to the
     Properties), except for such failures to comply that would not individually
     or in the aggregate have a Material Adverse Effect; and (G) neither the
     Company nor the Operating Partnership has knowledge of any pending or
     threatened condemnation proceedings, zoning change, or other proceeding or
     action that will in any manner affect the size of, use of, improvements on,

     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 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 

<PAGE>

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 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 

<PAGE>

     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 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 

<PAGE>

     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.

          (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)  During a period of 90 days from the date of any Prospectus
     Supplement relating to  Underwritten Securities, the Company and the
     Operating Partnership will not, without the prior written consent of the
     Representatives, directly or indirectly, sell, offer to sell, grant any
     option for the sale of, enter into any agreement to sell, or otherwise
     dispose of, (i) any securities of the same class or series or ranking on a
     parity with any Underwritten Securities (other than the Underwritten
     Securities covered by such Prospectus Supplement or any security
     convertible into or exchangeable for shares of such Underwritten Securities
     and (ii) if such Prospectus Supplement relates to Preferred Stock that is
     convertible into or exchangeable for Common Stock, any Common Stock or
     Units or any security convertible into or exchangeable for shares of Common
     Stock.  This transfer restriction does not apply to (i) the possible
     issuance of shares of Common Stock upon the exchange of Units by holders of
     Units other than DMI Partnership (except as to Units exchanged by DMI
     Partnership pursuant to a Unit bonus plan for employees of the Company and
     its subsidiaries) and the directors and executive officers of the Company;
     (ii) grants of options, and the issuance of shares in respect of such
     options, pursuant to a stock option plan; (iii) the issuance of shares
     pursuant to a dividend reinvestment plan; and (iv) the issuance of shares
     of Common Stock, or any security convertible into or exchangeable or
     exercisable for Common Stock, in connection with the acquisition of real
     property or an interest or interests in 

<PAGE>

     real property, if the recipient of such shares or other securities agrees
     in writing to not, without the prior written consent of Merrill Lynch, 
     Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and the Company and
     the Operating Partnership, directly or indirectly, sell, offer to sell,
     grant any option for the sale of, or otherwise dispose of any of such 
     securities until the expiration of a 90-day period from the date of any
     Prospectus Supplement.

          (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.

          (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

sale of the Underwritten Securities to the Underwriters, their transfer between
the Underwriters pursuant to an agreement between such Underwriters and the fees
and expenses of the transfer agent for the Underwritten Securities; (iv) the
fees and disbursements of the Company's and the Operating Partnership's counsel
and accountants; (v) the qualification of the Underwritten Securities and the
Common Stock issuable upon conversion of Preferred Stock, if any, under
securities laws and real estate syndication laws in accordance with the
provisions of Section 3(h) hereof, including filing fees and the fees and
disbursements of counsel for the  Underwriters in connection therewith and in
connection with the preparation of the Blue Sky Survey; (vi) the printing and
delivery to the Underwriters of copies of the Registration Statement as

the listing of the Underwritten Securities and the Common Stock issuable upon
conversion of Preferred Stock, if any, on the New York Stock Exchange, any other
national securities exchange or quotation system; (x) any fees charged by
nationally recognized statistical rating organizations for the rating of the

imposed on the sale of the Underwritten Securities to the several Underwriters.

          If this Agreement is cancelled or terminated by the Representatives in
accordance with the provisions of Section 5, Section 9(a)(i), Section 9(a)(iv)
or Section 9(a)(v) hereof, the Company and the Operating Partnership shall
reimburse the Underwriters for all of their out-of-pocket expenses, including
the reasonable fees and disbursements of counsel for the Underwriters.

     SECTION 5.  CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The obligations of
the Underwriters hereunder are

<PAGE>

subject to the accuracy, as of the date hereof and at Closing Time, of the 
representations and warranties of the Company and the Operating Partnership 
herein contained, to the performance by the Company and the Operating 
Partnership of their respective obligations hereunder, and to the following 
further conditions:

          (a)  At Closing Time, (i) no stop order suspending the effectiveness
     of the Registration Statement shall have been issued under the 1933 Act or
     proceedings therefor initiated or threatened by the Commission; (ii) if the
     Company or the Operating Partnership, as the case may be, has elected to
     rely upon Rule 430A of the 1933 Act Regulations, the public offering price
     of and the interest rate on the  Underwritten Securities, as the case may
     be, and any price-related information previously omitted from the effective
     Registration Statement pursuant to such Rule 430A shall have been
     transmitted to the Commission for filing pursuant to Rule 424(b) of the
     1933 Act Regulations within the prescribed time period, and prior to the
     applicable Closing Time, the Company or the Operating Partnership, as the
     case may be, shall have provided evidence satisfactory to the
     Representatives of such timely filing, or a post-effective amendment
     providing such information shall have been promptly filed and declared
     effective in accordance with the requirements of Rule 430A of the 1933 Act
     Regulations; (iii) if Preferred Stock is being offered, the rating assigned
     by any nationally recognized statistical rating organization as of the date
     of the applicable Terms Agreement shall not have been lowered since such
     date nor shall any such rating organization have publicly announced that it
     has placed the Preferred Stock on what is commonly termed a "watch list"
     for possible downgrading; (iv) 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 not have been lowered since such date nor shall any such
     rating organization 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; and (v) there shall not
     have come to the attention of the Representatives any facts that would
     cause the Representatives to believe that the Prospectus, together with the
     applicable Prospectus Supplement, at the time it was required to be
     delivered to purchasers of the  Underwritten Securities, included an untrue
     statement of a material fact or omitted to state a material fact necessary
     in order to make the statements therein, in light of the circumstances
     existing at such time, not misleading.  If a Rule 462(b) Registration
     Statement is required, such Rule 462(b) Registration Statement shall have
     been transmitted to the Commission for filing and have become effective
     within the prescribed time period, and, prior to Closing Time, the Company
     and the Operating Partnership shall have provided to the Underwriters
     evidence of such filing and effectiveness in accordance with Rule 462(b) of
     the 1933 Act Regulations.

          (b)  At Closing Time the Representatives shall have received:

               (1)  The favorable opinion, dated as of Closing Time, of Bose
          McKinney & Evans, counsel for each of the Company and the Operating
          Partnership and their respective subsidiaries in form and substance
          reasonably satisfactory to counsel for the Underwriters, to the effect
          that:

                       (i)    The Company is a corporation duly organized and
               existing under and by virtue of the laws of the State of Indiana,
               has filed its most recent annual report required by law with the
               Secretary of State of Indiana or is not yet required to file such
               annual report, and has not filed Articles of Dissolution.  The
               Company has corporate 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 and
               the other agreements to which it is a party.  The Company is duly
               qualified as a foreign corporation to transact business and is in

               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
               condition, financial or otherwise, or the earnings, assets,
               business affairs or business prospects of the Company or any
               Property.

               of the ownership or leasing of property or the conduct of
               business, except where the failure to so qualify or register
               would not have a material adverse effect on the condition, 
               financial or otherwise, or the earnings, assets, business affairs
               or business prospects of the Operating Partnership or any 
               Property or Related Business.

                     (iii)    Each of the Company's and the Operating
               Partnership's subsidiaries (other than the Property Partnerships)

                      (iv)    Each of the Company's and the Operating
               Partnership's 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

               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 condition, financial or otherwise,
               or the earnings, assets, business affairs or business prospects
               of the Duke Group considered as a single enterprise.

                       (v)    If the applicable Underwritten Securities are
               issued by the Company, and if the Prospectus contains the caption

               dividend reinvestment plans and the possible issuance of shares

               duly authorized and are validly issued, fully paid and non-
               assessable, except as provided under Indiana Code 
               Section 23-16-7-8.

                     (vii)    All of the issued and outstanding shares of
               capital stock and partnership interests, as the case may be, of
               each subsidiary identified in an exhibit to such counsel's
               opinion have been validly issued and fully paid and all such
               shares and partnership interests, as the case may be, that are
               owned by the Company, the Operating Partnership or a subsidiary,
               are in each case owned free and clear of any security interest,
               mortgage, pledge, lien, encumbrance, claim or equity.

                    (viii)    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 a limited liability company under of the laws of
               its jurisdiction of organization; each Property Partnership has
               all requisite power and authority to own, lease and operate the
               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.

                      (ix)    The applicable Underwritten Securities, if such
               Underwritten Securities are 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, 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, 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 contained in the
               Prospectus.  The form of stock or depositary certificate to be
               used to evidence the applicable Underwritten Securities is in due
               and proper form and complies with all applicable legal
               requirements.  The issuance of the applicable Underwritten
               Securities is not subject to any preemptive or other similar
               rights.

                       (x)    The applicable Underwritten Securities, if such
               Underwritten Securities are Debt Securities, are in the form
               contemplated in 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, 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 benefits of the Indenture and such Debt Securities will be
               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 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.

                     (xii)    To the best knowledge of such counsel, none of the
               entities comprising the Duke Group is in violation of its
               charter, by-laws, certificate of limited partnership or
               partnership agreement, as the case may be, and none of the
               entities comprising the Duke Group is 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 the property or assets of such entity is subject, except for
               defaults which are not material to the Duke Group as a whole.

                    (xiii)    Each of this Agreement, the applicable Terms
               Agreement and the Delayed Delivery Contracts, if any, were duly
               and validly authorized, executed and delivered by the Company and
               the Operating Partnership, as applicable, and the Company and the
               Operating Partnership have the power and authority to perform
               their obligations hereunder and thereunder.

               1939 Act and has been duly and validly authorized, executed and
               delivered by the Operating Partnership, and, assuming due

               a valid and binding obligation of the Operating Partnership,
               enforceable in accordance with its terms, except as such
               enforceability may be (1) limited by bankruptcy, insolvency,
               reorganization, liquidation, moratorium or 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).  The Indenture conforms in all material respects to the
               descriptions thereof contained in the Prospectus.

               subsidiaries identified in an exhibit to such counsel's opinion
               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, except as such
               enforceability may be (1) limited by bankruptcy, insolvency,
               reorganization, liquidation, moratorium or 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).

                     (xvi)    The execution and delivery of this Agreement, the
               applicable  Terms Agreement, any Indenture and the Underwritten
               Securities, the performance of 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 of 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

               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

               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

               threatened which are required to be disclosed in the Registration
               Statement or the Prospectus, other than those disclosed therein,
               and all pending legal or governmental proceedings to which any of
               the entities comprising the Duke Group is a party or to which any
               of their properties is subject which are not described in the
               Registration Statement or the Prospectus, including ordinary
               routine litigation incidental to the business, are, considered in
               the aggregate, not material.

                    (xxvi)    The information in the Prospectus under "The
               Company and the Operating Partnership," "Description of Debt
               Securities," "Description of Preferred Stock," "Description of
               Depositary Shares," "Description of Common Stock," and the
               information in the applicable Prospectus Supplement under similar
               sections and, if applicable, "The Company" or "The Operating
               Partnership," as the case may be, to the extent that it
               constitutes matters of law, summaries of legal matters, documents
               or proceedings, or legal conclusions, has been reviewed by them
               and is correct and presents fairly the information required to be
               disclosed therein.

<PAGE>

                    (xxvii)   There are no statutes, contracts, indentures,
               mortgages, loan agreements, notes, leases or other instruments
               known to such counsel which are required to be described or
               referred to in the Registration Statement or to be filed as
               exhibits thereto by the 1933 Act Regulations other than those
               described or referred to therein or filed as exhibits thereto,
               the descriptions thereof or references thereto are correct, and,
               to the best knowledge of such counsel, no material default exists
               in the due performance or observance of any material obligation,
               agreement, covenant or condition contained in any contract,
               indenture, mortgage, loan agreement, note, lease or other
               instrument so described, referred to or filed.

                    (xxviii)  To the best knowledge of such counsel, except as
               disclosed in the Prospectus and except for persons who received
               Units in connection with transactions with the Operating
               Partnership, there are no persons with registration or other
               similar rights to have any securities registered pursuant to the
               Registration Statement or otherwise registered by the Company or
               the Operating Partnership under the 1933 Act.

                    (xxix)    The Company and the Operating Partnership each
               satisfy all conditions and requirements for filing the
               Registration Statement on Form S-3 under the 1933 Act and 1933
               Act Regulations.

               (2)  The favorable opinion, dated as of the Closing Time, of
          Rogers & Wells LLP, counsel for the Underwriters, (A) with respect to
          the matters set forth in Section 5(b)(1)(i) (with respect to the
          Company only and with respect to the first sentence only), Section
          5(b)(1)(ix), (with respect to the first and last sentences only) or
          5(b)(1)(x) (with respect to the first sentence only), as applicable,
          Section 5(b)(1)(xiii) (with respect to the first clause only), Section
          5(b)(1)(xiv) and Section 5(b)(1)(xxiv) and (B) containing a statement
          similar to the statement referred to in the first paragraph of
          Section 5(b)(3).

               (3)  In giving their opinions required by subsections (b)(1) and
          (b)(2), respectively, of this Section, Bose McKinney & Evans and
          Rogers & Wells LLP shall additionally state that 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 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 and Rogers &
          Wells LLP may rely upon, or assume the accuracy of, (A) as to all
          matters of fact, certificates and written statements of officers and
          employees of and accountants for each of the entities comprising the
          Duke Group and (B) as to the qualification and good standing of each
          of the entities comprising the Duke Group to do business in any
          jurisdiction, certificates of appropriate government officials or
          opinions of counsel in such jurisdictions, and (C) in respect to the
          opinion by Rogers & Wells LLP only, as to certain matters of Indiana
          law, the opinion of Bose McKinney & Evans given pursuant to Section
          5(b)(1) above.

          (c)  At Closing Time, (i) no action, suit or proceeding at law or in
     equity shall be pending or, to 

<PAGE>

     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 Prospectus, any material adverse
     change in the condition, financial or otherwise, or in the earnings, 
     assets, business affairs or business prospects of any entity belonging 
     to the Duke Group, whether or not arising in the ordinary course
     of business; (iii) no proceedings shall be pending or threatened against
     such entity or any Property before or by any federal, state or other
     commission, board or administrative agency wherein an unfavorable decision,
     ruling or finding might result in any material adverse change 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
     any Property, as the case may be, other than as set forth in the
     Prospectus; (iv) no stop order suspending the effectiveness of the
     Registration Statement or any part thereof shall have been issued and no
     proceedings for that purpose shall have been instituted or threatened by
     the Commission or by the state securities authority of any jurisdiction;
     and (v) the Representatives shall have 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 Peat Marwick 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 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

<PAGE>

     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 Peat Marwick 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 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)  At Closing Time, the Representatives shall have received a letter
     agreement from DMI Partnership and from each director and executive officer
     of the Company and the Operating Partnership, wherein DMI Partnership and
     each such director or executive officer shall agree that during the period
     of 90 days from the date of any Prospectus Supplement they will not,
     without the prior written consent of Merrill Lynch, the Company and the
     Operating Partnership (which consent, in the case of the Company and the
     Operating Partnership, will be subject to the approval of the Company's
     unaffiliated directors), directly or indirectly, sell, offer to sell, grant
     any option for the sale of, enter into any agreement to sell, or otherwise
     dispose of, (i) any securities of the same class or series or ranking on a
     parity with any Underwritten Securities or any security convertible into or
     exchangeable for shares of such Underwritten Securities, and (ii) if such
     Prospectus Supplement relates to Preferred Stock that is convertible into
     or exchangeable for Common Stock, any Common Stock or Units or any security
     convertible into or exchangeable for shares of Common Stock.  Such transfer
     restrictions do not apply to Units exchanged by DMI Partnership pursuant to
     a Unit bonus plan for employees of the Company and its subsidiaries.  Such
     transfer restrictions do not apply to transfers to members of the family of
     such director or executive officer (or an entity for their benefit), or to
     the granting of a bona fide security interest to a secured party.  Any
     transferees of such shares, Units or other securities will be likewise
     prohibited from making any transfer of shares, Units or other securities.

          (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.

<PAGE>

               (2)  The favorable opinion of Bose McKinney & Evans, 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 Peat Marwick, 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.

          (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 Merrill Lynch 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 Merrill Lynch), 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 

<PAGE>

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 Merrill 
Lynch 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 
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 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.

<PAGE>

          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 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 to 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 the judgment 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 

<PAGE>

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.

          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
transmitted by any standard form of telecommunication.  Notices to the
Underwriters shall be directed to the Representatives at Merrill Lynch & Co.,
Merrill Lynch, Pierce Fenner & Smith Incorporated, Merrill Lynch World
Headquarters, North Tower, World Financial Center, New York, N.Y. 10281-1201,

Partnership shall be directed to any of them at 8888 Keystone Crossing, Suite
1200, Indianapolis, Indiana, 46240, attention of Darell E. Zink, Jr.

     SECTION 12.  PARTIES.  This Agreement and the applicable Terms Agreement
shall each inure to the benefit of and be binding upon the parties hereto and
their respective successors.  Nothing expressed or mentioned in this Agreement
or the applicable Terms Agreement is intended or shall be construed to give any
person, firm or corporation, other than those referred to in Sections 6 and 7
and their heirs and legal representatives, any legal or equitable right, remedy
or claim under or in respect of this Agreement or the applicable Terms Agreement
or any provision herein or therein contained.  This Agreement and the applicable
Terms Agreement and all conditions and provisions hereof and thereof are
intended to be for the sole and exclusive benefit of the parties hereto and
thereto and their respective successors, and said controlling persons and
officers and directors and their heirs and legal representatives, and for the
benefit of no other person, firm or corporation.  No purchaser of Underwritten
Securities from any Underwriter shall be deemed to be a successor by reason
merely of such purchase.

     SECTION 13.  GOVERNING LAW AND TIME.  This Agreement and the Terms
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.

October 15, 1998

Duke Realty Investments, Inc.
8888 Keystone Crossing, Suite 1200
Indianapolis, Indiana  46240

Gentlemen:

     We have acted as counsel to Duke Realty Investments, Inc., an Indiana
corporation (the "Company"), in connection with the shelf registration by the
Company of shares of the Company's common stock ("Common Stock") pursuant to a
Registration Statement, file no. 333-49911 (the "Registration Statement"), on
Form S-3 under the Securities Act of 1933, as amended.  The Company has filed a
prospectus supplement (the "Prospectus Supplement") relating to the offering of
650,000 shares of Common Stock.  In connection therewith, you have requested
our opinion regarding certain United States Federal income tax matters discussed
in the Prospectus Supplement.  All capitalized terms used herein have their
respective meanings as set forth in the Prospectus Supplement and accompanying
Prospectus unless otherwise stated.

     In rendering the opinions stated below, we have examined and relied, with
your consent, upon the Prospectus Supplement and the accompanying prospectus and
such other documents, records and instruments as we have deemed necessary in
order to enable us to render the opinion referred to in this letter.

     In our examination of the foregoing documents, we have assumed, with your
consent, that (i) all documents reviewed by us are original documents, or true
and accurate copies of original documents, and have not been subsequently
amended, (ii) the signatures on each original document are genuine, (iii) each
party who executed the document had proper authority and capacity, (iv) all
representations and statements set forth in such documents are true and correct,
and (v) all obligations imposed by any such documents on the parties thereto
have been or will be performed or satisfied in accordance with their terms.

     Based upon and subject to the foregoing, we are of the opinion that the
impact of the Taxpayer Relief Act of 1997 and the IRS Restructuring Act upon the
tax consequences of the ownership of Common Stock will be consistent with the
discussion contained in the section entitled "Certain Federal Income Tax
Considerations" in the Prospectus Supplement.

     The opinions set forth in this letter represent our conclusions as to 
the application of federal income tax laws existing as of the date of this 
letter to the transactions described herein.  We can give no assurance that 
legislative enactments, administrative changes or court decisions may not be 
forthcoming that would modify or supersede our opinions.  Moreover, there can 
be no assurance that positions contrary to our opinions will not be taken by 
the IRS, or that a court considering the issues would not hold contrary to 
such opinions. Further, the opinions set forth above represent our 
conclusions based upon the documents, facts and representations referred to 
above.  Any material amendments to such documents, changes in any significant 
facts or inaccuracy of such representations could affect the opinions 
referred to herein.  Although we have made such inquiries and performed such 
investigations as we have deemed necessary to fulfill our professional 
responsibilities as counsel, we have not undertaken an independent 
investigation of the facts referred to in this letter.

     We express no opinion as to any federal income tax issue or other matter
except those set forth or confirmed above.  We consent to the filing of this
opinion with Form 8-K, to the incorporation by reference of this opinion as an
exhibit to the registration statement of the Company and Duke Realty Limited
Partnership (file no. 333-49911) and any registration statement filed under Rule
462(b) relating to such registration statement and to the reference to our firm
under the heading "Legal Matters" in the Prospectus Supplement.

Very truly yours,

/s/ Bose McKinney & Evans
