Dear Sirs:

<Page>

      Duke-Weeks Realty Limited Partnership, an Indiana limited partnership (the
"Operating Partnership"), confirms its agreement with Merrill Lynch & Co.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, Bank One Capital Markets,
Inc., Credit Suisse First Boston Corporation, Deutsche Banc Alex. Brown Inc.,
Goldman, Sachs & Co., J.P. Morgan Securities Inc. and UBS Warburg LLC (each, an
"Agent", and collectively, the "Agents") with respect to the issue and sale by
the Operating Partnership of its Medium-Term Notes Due Nine Months or More From
Date of Issue (the "Notes"). The Notes are to be issued pursuant to an
Indenture, dated as of September 19, 1995, as amended or modified from time to
time (the "Indenture"), between the Operating Partnership and Bank One Trust
Company, N.A., as trustee (the "Trustee"). As of the date hereof, the Operating
Partnership has authorized the issuance and sale of up to U.S. $150,000,000
aggregate initial offering price of Notes (or its equivalent, based upon the
exchange rate on the applicable trade date in such foreign or composite
currencies as the Operating Partnership shall designate at the time of issuance)
to or through the Agents pursuant to the terms of this Agreement. It is
understood, however, that the Operating Partnership may from time to time
authorize the issuance of additional Notes and that such additional Notes may be
sold to or through the Agents pursuant to the terms of this Agreement, all as
though the issuance of such Notes were authorized as of the date hereof.

      This Agreement provides both for the sale of Notes by the Operating
Partnership to one or more Agents as principal for resale to investors and other
purchasers and for the sale of Notes by the Operating Partnership directly to
investors (as may from time to time be agreed to by the Operating Partnership
and the applicable Agent), in which case the applicable Agent will act as an
agent of the Operating Partnership in soliciting offers for the purchase of
Notes.

      Duke-Weeks Realty Corporation (the "Company") and the Operating
Partnership have filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-37920) for the
registration of debt securities of the Operating Partnership, including the
Notes, and of common stock, preferred stock and depositary shares of the Company
under the Securities Act of 1933, as amended (the "1933 Act"), and the offering
thereof from time to time in accordance with Rule 415 of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations").
Such registration statement has been declared effective by the Commission and
the Indenture has been duly qualified under the Trust Indenture Act of 1939, as
amended (the "1939 Act"), and the Operating Partnership has filed such
post-effective amendments thereto as may be required prior to its acceptance of
any offer for the purchase of Notes and each such post-effective amendment has
been declared effective by the Commission. Such registration statement (as so
amended, if applicable) is referred to herein as the "Registration Statement";
and the final prospectus and all applicable amendments or supplements thereto
(including the final prospectus supplement and pricing supplement relating to
the offering of Notes), in the form first furnished to the applicable Agent(s)
for use in confirming sales of Notes, are collectively referred to herein as the
"Prospectus"; provided, however, that all references to the "Registration
Statement" and the "Prospectus" shall also be deemed to include all documents
incorporated therein by reference pursuant to the Securities Exchange Act of
1934, as amended (the "1934 Act"), prior to any acceptance by the Operating
Partnership of an offer for the purchase of Notes; provided, further, that if
the Operating Partnership files a registration statement with the Commission
pursuant to Rule 462(b) of the 1933 Act Regulations (the "Rule 462(b)
Registration Statement"),


                                       2
<Page>

then, after such filing, all references to the "Registration Statement" shall
also be deemed to include the Rule 462(b) Registration Statement. A "preliminary
prospectus" shall be deemed to refer to any prospectus used before the
Registration Statement became effective and any prospectus furnished by the
Operating Partnership after the registration statement became effective and
before any acceptance by the Operating Partnership of an offer for the purchase
of Notes which omitted information to be included upon pricing in a form of
prospectus filed with the Commission pursuant to Rule 424(b) of the 1933 Act
Regulations. For purposes of this Agreement, all references to the Registration
Statement, Prospectus or preliminary prospectus or to any amendment or
supplement thereto shall be deemed to include any copy filed with the Commission
pursuant to its Electronic Data Gathering, Analysis and Retrieval system
("EDGAR").

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

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

      The term "Duke Group" means the Company, the Operating Partnership and any
subsidiary (a "Property Partnership") which directly or indirectly owns any real
property (a "Property").

      SECTION 1. APPOINTMENT AS AGENT.

      (a) APPOINTMENT. Subject to the terms and conditions stated herein and
subject to the reservation by the Operating Partnership of the right to sell
Notes directly on its own behalf, the Operating Partnership hereby agrees that
Notes will be sold exclusively to or through the Agents. The Operating
Partnership agrees that it will not appoint any other agents to act on its
behalf, or to assist it, in the placement of the Notes.

      (b) SALE OF NOTES. The Operating Partnership shall not sell or approve the
solicitation of offers for the purchase of Notes in excess of the amount which
shall be authorized by the Operating Partnership from time to time or in excess
of the aggregate initial offering price of Notes registered pursuant to the
Registration Statement. The Agents shall have no responsibility for maintaining
records with respect to the aggregate initial offering price of Notes sold, or
of otherwise monitoring the availability of Notes for sale, under the
Registration Statement.


                                       3

      (c) PURCHASES AS PRINCIPAL. The Agents shall not have any obligation to
purchase Notes from the Operating Partnership as principal. However, absent an
agreement between an Agent and the Operating Partnership that such Agent shall
be acting solely as an agent for the Operating Partnership, such Agent shall be
deemed to be acting as principal in connection with any offering of Notes by the
Operating Partnership through such Agent. Accordingly, the Agents, individually
or in a syndicate, may agree from time to time to purchase Notes from the
Operating Partnership as principal for resale to investors and other purchasers
determined by such Agents. Any purchase of Notes from the Operating Partnership
by an Agent as principal shall be made in accordance with Section 3(a) hereof.

      (d) SOLICITATIONS AS AGENT. If agreed upon between an Agent and the
Operating Partnership, such Agent, acting solely as an agent for the Operating
Partnership and not as principal, will solicit offers for the purchase of Notes.
Such Agent will communicate to the Operating Partnership, orally, each offer for
the purchase of Notes solicited by it on an agency basis other than those offers
rejected by such Agent. Such Agent shall have the right, in its discretion
reasonably exercised, to reject any offer for the purchase of Notes, in whole or
in part, and any such rejection shall not be deemed a breach of its agreement
contained herein. The Operating Partnership may accept or reject any offer for
the purchase of Notes, in whole or in part. Such Agent shall make reasonable
efforts to assist the Operating Partnership in obtaining performance by each
purchaser whose offer for the purchase of Notes has been solicited by it on an
agency basis and accepted by the Operating Partnership. Such Agent shall not
have any liability to the Operating Partnership in the event that any such
purchase is not consummated for any reason. If the Operating Partnership shall
default on its obligation to deliver Notes to a purchaser whose offer has been
solicited by such Agent on an agency basis and accepted by the Operating
Partnership, the Operating Partnership shall (i) hold such Agent harmless
against any loss, claim or damage arising from or as a result of such default by
the Operating Partnership and (ii) pay to such Agent any commission to which it
would otherwise be entitled absent such default.

      (e) RELIANCE. The Operating Partnership and the Agents agree that any
Notes purchased from the Operating Partnership by one or more Agents as
principal shall be purchased, and any Notes the placement of which an Agent
arranges as an agent of the Operating Partnership shall be placed by such Agent,
in reliance on the representations, warranties, covenants and agreements of the
Operating Partnership contained herein and on the terms and conditions and in
the manner provided herein.

SECTION 2. REPRESENTATIONS AND WARRANTIES.

      (a) The Operating Partnership represents and warrants to each Agent as of
the date hereof, as of the date of each acceptance by the Operating Partnership
of an offer for the purchase of Notes (whether to such Agent as principal or
through such Agent as agent), as of the date of each delivery of Notes (whether
to such Agent as principal or through such Agent as agent) (the date of each
such delivery to such Agent as principal is referred to herein as a "Settlement
Date"), and as of any time that the Registration Statement or the Prospectus
shall be amended or supplemented (each of the times referenced above is referred
to herein as a "Representation Date"), as follows:


                                       4
<Page>

            (i) DUE ORGANIZATION, GOOD STANDING AND DUE QUALIFICATION OF THE
      COMPANY AND THE OPERATING PARTNERSHIP. Each of the Company and the
      Operating Partnership has been duly organized and is validly existing as a
      corporation or limited partnership in good standing under the laws of the
      State of Indiana with corporate or partnership power and authority to own,
      lease and operate its properties and to conduct its business as described
      in the Prospectus and to enter into this Agreement and consummate the
      transactions contemplated in the Prospectus; each of the Company and the
      Operating Partnership is duly qualified as a foreign corporation or
      limited partnership to transact business and is in good standing 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 or be in good standing would not result in
      a material adverse change in the condition, financial or otherwise, or in
      the earnings, business affairs or business prospects of the Duke Group
      considered as one enterprise (a "Material Adverse Effect"); all of the
      issued and outstanding Units of the Operating Partnership have been duly
      authorized and are validly issued, fully paid and non-assessable, except
      as provided under Indiana Code ss.23-16-7-8; and none of the outstanding
      Units of the Operating Partnership were issued in violation of preemptive
      or other similar rights of any securityholder of the Operating
      Partnership.

            (ii) DUE INCORPORATION, GOOD STANDING AND DUE QUALIFICATION OF
      SIGNIFICANT SUBSIDIARIES. Each significant subsidiary (as such term is
      defined in Rule 1-02 of Regulation S-X promulgated under the 1933 Act), if
      any (each, a "Significant Subsidiary") has been duly organized and is
      validly existing as a corporation, partnership or limited liability
      company in good standing under the laws of the jurisdiction of its
      incorporation, has corporate, partnership or limited liability company
      power and authority to own, lease and operate its properties and conduct
      its business as described in the Prospectus and is duly qualified as a
      foreign corporation, partnership or limited liability company to transact
      business and is in good standing 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 or be in good standing would not result in a Material Adverse
      Effect; except as stated in the Prospectus, all of the issued and
      outstanding shares of capital stock or partnership or limited liability
      company interests of each Significant Subsidiary have been duly authorized
      and are validly issued, fully paid and non-assessable (except, as to
      partnerships, as provided under Indiana Code ss.23-16-7-8) and is owned by
      the Company or the Operating Partnership, directly or through
      subsidiaries, free and clear of any security interest, mortgage, pledge,
      lien, encumbrance, claim or equity; and none of the outstanding shares of
      capital stock or partnership or limited liability company interests of any
      Significant Subsidiary was issued in violation of preemptive or other
      similar rights of any securityholder of such Significant Subsidiary.

            (iii) REGISTRATION STATEMENT AND PROSPECTUS. The Operating
      Partnership meets the requirements for use of Form S-3 under the 1933 Act;
      the Registration Statement (or any Rule 462(b) Registration Statement) has
      become effective under the 1933 Act and no stop order suspending the
      effectiveness of the Registration Statement (or any Rule


                                       5
<Page>

      462(b) Registration Statement) has been issued under the 1933 Act and no
      proceedings for that purpose have been instituted or are pending or, to
      the knowledge of the Operating Partnership, are contemplated by the
      Commission, and any request on the part of the Commission for additional
      information has been complied with; the Indenture has been duly qualified
      under the 1939 Act; at the respective times that the Registration
      Statement (including any Rule 462(b) Registration Statement) and any
      post-effective amendment thereto (including the filing of the Operating
      Partnership's most recent Annual Report on Form 10-K with the Commission
      (the "Annual Report on Form 10-K")) became effective and at each
      Representation Date, the Registration Statement (including any Rule 462(b)
      Registration Statement) and any amendments thereto complied and will
      comply in all material respects with the requirements of the 1933 Act and
      the 1933 Act Regulations and the 1939 Act and the rules and regulations of
      the Commission under the 1939 Act (the "1939 Act Regulations") and did not
      and will not contain an untrue statement of a material fact or omit to
      state a material fact required to be stated therein or necessary to make
      the statements therein not misleading; each preliminary prospectus and
      prospectus filed as part of the Registration Statement as originally filed
      or as part of any amendment thereto, or filed pursuant to Rule 424 under
      the 1933 Act, complied when so filed in all material respects with the
      1933 Act Regulations; each preliminary prospectus and the Prospectus
      delivered to the applicable Agent(s) for use in connection with the
      offering of Notes are identical to any electronically transmitted copies
      thereof filed with the Commission pursuant to EDGAR, except to the extent
      permitted by Regulation S-T; and at the date hereof, at the date of the
      Prospectus and each amendment or supplement thereto and at each
      Representation Date, neither the Prospectus nor any amendment or
      supplement thereto included or will include an untrue statement of a
      material fact or omitted or will omit to state a material fact necessary
      in order to make the statements therein, in the light of the circumstances
      under which they were made, not misleading; provided, however, that the
      representations and warranties in this subsection shall not apply to
      statements in or omissions from the Registration Statement or the
      Prospectus made in reliance upon and in conformity with information
      furnished to the Operating Partnership in writing by the Agents expressly
      for use in the Registration Statement or the Prospectus.

            (iv) INCORPORATED DOCUMENTS. The documents incorporated or deemed to
      be incorporated by reference in the Prospectus, 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 date hereof, at the date of the Prospectus and at each
      Representation Date, did not and will not include an untrue statement of a
      material fact or omit to state a material fact necessary in order to make
      the statements therein, in the light of the circumstances under which they
      were made, not misleading.

            (v) INDEPENDENT ACCOUNTANTS. The accountants who certified the
      financial statements and any supporting schedules thereto included in the
      Registration Statement and the Prospectus are independent public
      accountants as required by the 1933 Act and the 1933 Act Regulations.


                                       6
<Page>

            (vi) FINANCIAL STATEMENTS. The consolidated financial statements of
      the Operating Partnership included in the Registration Statement and the
      Prospectus, together with the related schedules and notes, as well as
      those financial statements, schedules and notes of any other entity
      included in the Registration Statement and the Prospectus, present fairly
      the consolidated financial position of the Operating Partnership and its
      subsidiaries, or such other entity, as the case may be, at the dates
      indicated and the consolidated statement of operations, stockholders'
      equity and cash flows of the Operating Partnership and its subsidiaries,
      or such other entity, as the case may be, for the periods specified; such
      financial statements have been prepared in conformity with generally
      accepted accounting principles ("GAAP") applied on a consistent basis
      throughout the periods involved; the supporting schedules, if any,
      included in the Registration Statement and the Prospectus present fairly
      in accordance with GAAP the information required to be stated therein; the
      selected financial data and the summary financial information included in
      the Registration Statement and the Prospectus present fairly the
      information shown therein and have been compiled on a basis consistent
      with that of the audited financial statements included in the Registration
      Statement and the Prospectus; and any pro forma consolidated financial
      statements of the Operating Partnership and its subsidiaries and the
      related notes thereto included in the Registration Statement and the
      Prospectus present fairly the information shown therein, have been
      prepared in accordance with the Commission's rules and guidelines with
      respect to pro forma financial statements and have been properly compiled
      on the bases described therein, and the assumptions used in the
      preparation thereof are reasonable and the adjustments used therein are
      appropriate to give effect to the transactions and circumstances referred
      to therein.

            (vii) NO MATERIAL CHANGES. Since the respective dates as of which
      information is given in the Registration Statement and the Prospectus,
      except as otherwise stated therein, (1) there has been no event or
      occurrence that would result in a Material Adverse Effect and (2) there
      have been no transactions entered into by the Duke Group, other than those
      in the ordinary course of business, which are material with respect to the
      Duke Group considered as one enterprise.

            (viii) AUTHORIZATION, ETC. OF THIS AGREEMENT, THE INDENTURE AND THE
      NOTES. This Agreement has been duly authorized, executed and delivered by
      the Operating Partnership; the Indenture has been duly authorized,
      executed and delivered by the Operating Partnership and will be a valid
      and legally binding agreement of the Operating Partnership, enforceable
      against the Operating Partnership in accordance with its terms, except as
      enforcement thereof may be limited by bankruptcy, insolvency,
      reorganization, moratorium or other similar laws affecting the enforcement
      of creditors' rights generally or by general equitable principles
      (regardless of whether enforcement is considered in a proceeding in equity
      or at law), and except further as enforcement thereof may be limited by
      requirements that a claim with respect to any debt securities issued under
      the Indenture that are payable in a foreign or composite currency (or a
      foreign or composite currency judgment in respect of such claim) be
      converted into U.S. dollars at a rate of exchange prevailing on a date
      determined pursuant to applicable law or by governmental authority to
      limit, delay or


                                       7
<Page>

      prohibit the making of payments outside the United States; the Notes have
      been duly authorized by the Operating Partnership for offer, sale,
      issuance and delivery pursuant to this Agreement and, when issued,
      authenticated and delivered in the manner provided for in the Indenture
      and delivered against payment of the consideration therefor, will
      constitute valid and legally binding obligations of the Operating
      Partnership, enforceable against the Operating Partnership in accordance
      with their terms, except as enforcement thereof may be limited by
      bankruptcy, insolvency, reorganization, moratorium or other similar laws
      affecting the enforcement of creditors' rights generally or by general
      equitable principles (regardless of whether enforcement is considered in a
      proceeding in equity or at law), and except further as enforcement thereof
      may be limited by requirements that a claim with respect to any Notes
      payable in a foreign or composite currency (or a foreign or composite
      currency judgment in respect of such claim) be converted into U.S. dollars
      at a rate or exchange prevailing on a date determined pursuant to
      applicable law or by governmental authority to limit, delay or prohibit
      the making of payments outside the United States; the Notes will be
      substantially in a form previously certified to the Agents and
      contemplated by the Indenture; and each holder of Notes will be entitled
      to the benefits of the Indenture.

            (ix) DESCRIPTIONS OF THE INDENTURE AND THE NOTES. The Indenture and
      the Notes conform and will conform in all material respects to the
      statements relating thereto contained in the Prospectus and are
      substantially in the form filed or incorporated by reference, as the case
      may be, as an exhibit to the Registration Statement.

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

            (xi) ABSENCE OF DEFAULTS AND CONFLICTS. None of the entities
      comprising the Duke Group is in violation of the provisions of its charter
      or by-laws, certificate of limited partnership, partnership agreement or
      corresponding organizational documents or in default in the performance or
      observance of any obligation, agreement, covenant or condition contained
      in any contract, indenture, mortgage, deed of trust, loan or credit
      agreement, note, lease or other agreement or instrument to which any
      member of the Duke Group is a party or by which any of them may be bound
      or to which any of the property or assets of the Duke Group is subject
      (collectively, "Agreements and Instruments"), except for such defaults
      that would not result in a Material Adverse Effect; and the execution,
      delivery and performance of this Agreement, the Indenture, the Notes and
      any other agreement or instrument entered into or issued or to be entered
      into or issued by the Operating Partnership in connection with the
      transactions contemplated by the Prospectus, the consummation of the
      transactions contemplated in the Prospectus (including the issuance and
      sale of the Notes and the use of proceeds therefrom as described in the
      Prospectus) and the compliance by the Operating Partnership with its
      obligations hereunder and under the Indenture, the Notes and such other
      agreements or instruments have been duly authorized by all necessary
      corporate action and do not and will not, whether with or without the
      giving of notice or the passage of time or both, conflict with or
      constitute a breach of, or default or event or


                                       8
<Page>

      condition which gives the holder of any note, debenture or other evidence
      of indebtedness (or any person acting on such holder's behalf) the right
      to require the repurchase, redemption or repayment of all or a portion of
      such indebtedness by any member of the Duke Group (a "Repayment Event")
      under, or result in the creation or imposition of any lien, charge or
      encumbrance upon any assets, properties or operations of any member of the
      Duke Group pursuant to, any Agreements and Instruments, nor will such
      action result in any violation of the provisions of the charter or
      by-laws, certificate of limited partnership, partnership agreement or
      corresponding organizational documents of any member of the Duke Group or
      any applicable law, statute, rule, regulation, judgment, order, writ or
      decree of any government, government instrumentality or court, domestic or
      foreign, having jurisdiction over any member of the Duke Group or any of
      their assets, properties or operations.

            (xii) ABSENCE OF LABOR DISPUTES. No labor dispute with the employees
      of the Duke Group exists or, to the knowledge of the Operating
      Partnership, is imminent, and the Operating Partnership is not aware of
      any existing or imminent labor disturbance by the employees of any of the
      principal suppliers, manufacturers, customers or contractors to any member
      of the Duke Group, which, in either case, may reasonably be expected to
      result in a Material Adverse Effect.

            (xiii) ABSENCE OF PROCEEDINGS. There is no action, suit, proceeding,
      inquiry or investigation before or brought by any court or governmental
      agency or body, domestic or foreign, now pending, or to the knowledge of
      the Operating Partnership threatened, against or affecting any member of
      the Duke Group which is required to be disclosed in the Registration
      Statement and the Prospectus (other than as stated therein), or which may
      reasonably be expected to result in a Material Adverse Effect, or which

      Prospectus; and the aggregate of all pending legal or governmental
      proceedings to which any member of the Duke Group is a party or of which
      any of their respective assets, properties or operations is the subject

      the Governmental Licenses are valid and in full force and effect, except
      where the invalidity of such Governmental Licenses or the failure of such

      received any notice of proceedings relating to the revocation or
      modification of any such Governmental Licenses which, singly or in the
      aggregate, if the subject of an unfavorable decision, ruling or finding,
      would result in a Material Adverse Effect.

                                       11
<Page>

      ("1940 Act").

            (xx) COMMODITY EXCHANGE ACT. The Notes, upon issuance, will be
      excluded or exempted under, or beyond the purview of, the Commodity
      Exchange Act, as amended (the "Commodity Exchange Act"), and the rules and

Agent or Agents as to the matters covered thereby on the date of such
certificate and, unless subsequently amended or supplemented, at each
Representation Date subsequent thereto.

SECTION 3. PURCHASES AS PRINCIPAL; SOLICITATIONS AS AGENT.

      (a) PURCHASES AS PRINCIPAL. Notes purchased from the Operating Partnership
by the Agents, individually or in a syndicate, as principal shall be made in
accordance with terms agreed upon between such Agent or Agents and the Operating
Partnership (which terms, unless otherwise agreed, shall, to the extent
applicable, include those terms specified in Exhibit A hereto and shall be
agreed upon orally, with written confirmation prepared by such Agent or Agents
and mailed to the Operating Partnership). An Agent's commitment to purchase
Notes as principal shall be deemed to have been made on the basis of the
representations and warranties of the Operating Partnership herein contained and
shall be subject to the terms and conditions herein set forth. Unless the
context otherwise requires, references herein to "this Agreement" shall include
the applicable agreement of one or more Agents to purchase Notes from the
Operating Partnership as principal. Each purchase of Notes, unless otherwise
agreed, shall be at a discount from the principal amount of each such Note
equivalent to the applicable commission set forth in Schedule A hereto. The
Agents may engage the services of any broker or dealer in connection with the
resale of the Notes purchased by them as principal and may allow all or any
portion of the discount received from the Operating Partnership in connection
with such purchases to such brokers or dealers. At the time of each purchase of
Notes from the Operating Partnership by one or more Agents as principal, such
Agent or Agents shall specify the requirements for the officers' certificate,
opinion of counsel and comfort letter pursuant to Sections 7(b), 7(c) and 7(d)
hereof.

      If the Operating Partnership and two or more Agents enter into an
agreement pursuant to which such Agents agree to purchase Notes from the
Operating Partnership as principal and one or more of such Agents shall fail at
the Settlement Date to purchase the Notes which it or they are


                                       12
<Page>

obligated to purchase (the "Defaulted Notes"), then the nondefaulting Agents
shall have the right, within 24 hours thereafter, to make arrangements for one
of them or one or more other Agents or underwriters to purchase all, but not
less than all, of the Defaulted Notes in such amounts as may be agreed upon and
upon the terms herein set forth; provided, however, that if such arrangements
shall not have been completed within such 24-hour period, then:

            (a) if the aggregate principal amount of Defaulted Notes does not
      exceed 10% of the aggregate principal amount of Notes to be so purchased
      by all of such Agents on the Settlement Date, the nondefaulting Agents
      shall be obligated, severally and not jointly, to purchase the full amount
      thereof in the proportions that their respective initial underwriting
      obligations bear to the underwriting obligations of all nondefaulting
      Agents; or

            (b) if the aggregate principal amount of Defaulted Notes exceeds 10%
      of the aggregate principal amount of Notes to be so purchased by all of
      such Agents on the Settlement Date, such agreement shall terminate without
      liability on the part of any nondefaulting Agent.

No action taken pursuant to this paragraph shall relieve any defaulting Agent
from liability in respect of its default. In the event of any such default which
does not result in a termination of such agreement, either the nondefaulting
Agents or the Operating Partnership shall have the right to postpone the
Settlement Date 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.

      (b) SOLICITATIONS AS AGENT. On the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, when agreed by the Operating Partnership and an Agent, such Agent, as an
agent of the Operating Partnership, will use its reasonable efforts to solicit
offers for the purchase of Notes upon the terms set forth in the Prospectus. The
Agents are not authorized to appoint sub-agents with respect to Notes sold
through them as agent. All Notes sold through an Agent as agent will be sold at
100% of their principal amount unless otherwise agreed upon between the
Operating Partnership and such Agent.

      The Operating Partnership reserves the right, in its sole discretion, to
suspend solicitation of offers for the purchase of Notes through an Agent, as an
agent of the Operating Partnership, commencing at any time for any period of
time or permanently. As soon as practicable after receipt of instructions from
the Operating Partnership, such Agent will suspend solicitation of offers for
the purchase of Notes from the Operating Partnership until such time as the
Operating Partnership has advised such Agent that such solicitation may be
resumed.

      The Operating Partnership agrees to pay each Agent a commission, in the
form of a discount, equal to the applicable percentage of the principal amount
of each Note sold by the Operating Partnership as a result of a solicitation
made by such Agent, as an agent of the Operating Partnership, as set forth in
Schedule A hereto.

      (c) ADMINISTRATIVE PROCEDURES. The purchase price, interest rate or
formula, maturity date and other terms of the Notes specified in Exhibit A
hereto (as applicable) shall be agreed upon


                                       13
<Page>

between the Operating Partnership and the applicable Agent(s) and specified in a
pricing supplement to the Prospectus (each, a "Pricing Supplement") to be
prepared by the Operating Partnership in connection with each sale of Notes.
Except as otherwise specified in the applicable Pricing Supplement, the Notes
will be issued in denominations of U.S. $1,000 or any larger amount that is an
integral multiple of U.S. $1,000. Administrative procedures with respect to the
issuance and sale of the Notes (the "Procedures") shall be agreed upon from time
to time among the Operating Partnership, the Agents and the Trustee. The Agents
and the Operating Partnership agree to perform, and the Operating Partnership
agrees to cause the Trustee to agree to perform, their respective duties and
obligations specifically provided to be performed by them in the Procedures.

SECTION 4. COVENANTS OF THE OPERATING PARTNERSHIP.

      The Operating Partnership covenants and agrees with each Agent as follows:

      (a) NOTICE OF CERTAIN EVENTS. The Operating Partnership will notify the
Agents immediately, and confirm such notice in writing, of (i) the effectiveness
of any post-effective amendment to the Registration Statement or the filing of
any amendment or supplement to the Prospectus (other than any amendment or
supplement thereto providing solely for the determination of the variable terms
of the Notes or relating solely to the offering of securities other than the
Notes), (ii) the receipt of any comments from the Commission with respect to the
Registration Statement or the Prospectus, (iii) any request by the Commission
for any amendment to the Registration Statement or any amendment or supplement

organization to the Program or any debt securities (including the Notes) of the
Operating Partnership, or the public announcement by any nationally recognized
statistical rating organization that it has under surveillance or review, with
possible negative implications, its rating of the Program or any such debt
securities, or the withdrawal by any nationally recognized statistical rating
organization of its rating of the Program or any such debt securities. The
Operating Partnership will make every reasonable effort to prevent the issuance
of any stop order and, if any stop order is issued, to obtain the lifting
thereof at the earliest possible moment.

      (b) FILING OR USE OF AMENDMENTS. The Operating Partnership will give the
Agents advance notice of its intention to file or prepare any additional
registration statement with respect to the registration of additional Notes, any
amendment to the Registration Statement (including any filing under Rule 462(b)
of the 1933 Act Regulations) or any amendment or supplement to the prospectus
included in the Registration Statement at the time it became effective or to the
Prospectus (other than an amendment or supplement thereto providing solely for
the determination of the variable terms of the Notes or relating solely to the
offering of securities other than the Notes), whether pursuant to the 1933 Act,
the 1934 Act or otherwise, will furnish to the Agents copies of any such
document a reasonable amount of time prior to such proposed filing or use, as
the case may be, and will not file any such document to which the Agents or
counsel for the Agents shall reasonably object.

Partnership will furnish to each Agent, without charge, such number of copies of
the Prospectus (as amended or supplemented) as such Agent may reasonably
request. The Prospectus and any amendments or supplements thereto furnished to
the Agents will be identical to any electronically transmitted copies thereof
filed with the Commission pursuant to EDGAR, except to the extent permitted by
Regulation S-T.

      (e) PREPARATION OF PRICING SUPPLEMENTS. The Operating Partnership will
prepare, with respect to any Notes to be sold to or through one or more Agents

Registration Statement will not contain an untrue statement of a material fact

make the statements therein not misleading or to amend or supplement the
Prospectus in order that the Prospectus will not include an untrue statement of
a material fact or omit to state a material fact necessary in order to make the

the time the Prospectus is delivered to a purchaser, or if it shall be
necessary, in the opinion of either such counsel, to amend the Registration

Partnership shall give immediate notice, confirmed in writing, to the Agents to
cease the solicitation of offers for the purchase of Notes in their capacity as
agents and to cease sales of any Notes they may then own as principal, and the
Operating Partnership will promptly prepare and file with the Commission,
subject to Section 4(b) hereof, whether by filing documents pursuant to the 1934
Act or the 1933 Act or otherwise, such amendment or supplement as may be
necessary to correct such


                                       15

Operating Partnership in connection with the issuance and sale of Notes as

and to counsel to the Agents.

      If any condition specified in this Section 5 shall not have been fulfilled

SECTION 6. DELIVERY OF AND PAYMENT FOR NOTES SOLD THROUGH AN AGENT AS AGENT.

      Delivery of Notes sold through an Agent as an agent of the Operating
Partnership shall be made by the Operating Partnership to such Agent for the
account of any purchaser only against payment therefor in immediately available
funds. In the event that a purchaser shall fail either to accept delivery of or
to make payment for a Note on the date fixed for settlement, such Agent shall
promptly notify the Operating Partnership and deliver such Note to the Operating
Partnership and, if such Agent has theretofore paid the Operating Partnership
for such Note, the Operating Partnership will promptly return such funds to such
Agent. If such failure has occurred for any reason other than default by such
Agent in the performance of its obligations hereunder, the Operating Partnership
will reimburse such Agent on an equitable basis for its loss of the use of the
funds for the period such funds were credited to the Operating Partnership's
account.

SECTION 7. ADDITIONAL COVENANTS OF THE OPERATING PARTNERSHIP.

      The Operating Partnership further covenants and agrees with each Agent as
follows:

      (a) REAFFIRMATION OF REPRESENTATIONS AND WARRANTIES. Each acceptance by
the Operating Partnership of an offer for the purchase of Notes (whether to one
or more Agents as principal or through an Agent as agent), and each delivery of
Notes (whether to one or more Agents as principal or through an Agent as agent),
shall be deemed to be an affirmation that the representations and warranties of
the Operating Partnership herein contained and contained in any certificate
theretofore delivered to the Agents pursuant hereto are true and correct at the
time of such acceptance or sale, as the case may be, and an undertaking that
such representations and warranties will be true and correct at the time of
delivery to such Agent(s) or to the purchaser or its agent, as the case may be,
of the Notes relating to such acceptance or sale, as the case may be, as though
made at and as of each such time (it being understood that such representations
and warranties shall relate to the Registration Statement and Prospectus as
amended and supplemented to each such time).

      (b) SUBSEQUENT DELIVERY OF CERTIFICATES. Each time that (i) the
Registration Statement or the Prospectus shall be amended or supplemented (other
than by an amendment or supplement providing solely for the determination of the
variable terms of the Notes or relating solely to the offering of securities
other than the Notes), (ii) (if required in connection with the purchase of
Notes from the Operating Partnership by one or more Agents as principal) the
Operating Partnership sells Notes to one or more Agents as principal or (iii)
the Operating Partnership sells Notes in a form not previously certified to the

cause to be furnished to the Agent(s), forthwith a certificate dated the date of
filing with the Commission or the date of effectiveness of such amendment or
supplement, as applicable, or the date of such sale, as the case may be, in form
satisfactory to the Agent(s) to the effect that the statements contained in the
certificate referred to in Section 5(c) hereof which were last furnished to the
Agents are true and correct at the time of the filing or effectiveness of such
amendment or supplement, as applicable, or the time of such sale, as the case
may be, as though made at and as of such time (except that such statements shall
be deemed to relate to the Registration Statement and


                                       19
<Page>

the Prospectus as amended and supplemented to such time) or, in lieu of such
certificate, a certificate of the same tenor as the certificate referred to in
Section 5(c) hereof, modified as necessary to relate to the Registration
Statement and the Prospectus as amended and supplemented to the time of delivery
of such certificate (it being understood that, in the case of clause (ii) above,
any such certificate shall also include a certification that there has been no
material adverse change in the condition, financial or otherwise, or in the
earnings, business affairs or business prospects of the Duke Group considered as
one enterprise since the date of the agreement by such Agent(s) to purchase
Notes from the Operating Partnership as principal).

      (c) SUBSEQUENT DELIVERY OF LEGAL OPINIONS. Each time that (i) the
Registration Statement or the Prospectus shall be amended or supplemented (other
than by an amendment or supplement providing solely for the determination of the
variable terms of the Notes or relating solely to the offering of securities
other than the Notes), (ii) (if required in connection with the purchase of
Notes from the Operating Partnership by one or more Agents as principal) the
Operating Partnership sells Notes to one or more Agents as principal or (iii)
the Operating Partnership sells Notes in a form not previously certified to the
Agents by the Operating Partnership, the Operating Partnership shall furnish or
cause to be furnished forthwith to the Agent(s) and to counsel to the Agents the
written opinion of Bose McKinney & Evans LLP, counsel to the Operating
Partnership, or other counsel satisfactory to the Agent(s), dated the date of
filing with the Commission or the date of effectiveness of such amendment or
supplement, as applicable, or the date of such sale, as the case may be, in form
and substance satisfactory to the Agent(s), of the same tenor as the opinion
referred to in Section 5(b)(1) hereof, but modified, as necessary, to relate to
the Registration Statement and the Prospectus as amended and supplemented to the
time of delivery of such opinion or, in lieu of such opinion, counsel last
furnishing such opinion to the Agents shall furnish the Agent(s) with a letter
substantially to the effect that the Agent(s) may rely on such last opinion to
the same extent as though it was dated the date of such letter authorizing
reliance (except that statements in such last opinion shall be deemed to relate
to the Registration Statement and the Prospectus as amended and supplemented to
the time of delivery of such letter authorizing reliance).

      (d) SUBSEQUENT DELIVERY OF COMFORT LETTERS. Each time that (i) the
Registration Statement or the Prospectus shall be amended or supplemented to
include additional financial information (other than by an amendment or
supplement relating solely to the issuance and/or offering of securities other
than the Notes) or (ii) (if required in connection with the purchase of Notes
from the Operating Partnership by one or more Agents as principal) the Operating
Partnership sells Notes to one or more Agents as principal, the Operating
Partnership shall cause KPMG, LLP forthwith to furnish to the Agent(s) a letter,
dated the date of filing with the Commission or the date of effectiveness of
such amendment or supplement, as applicable, or the date of such sale, as the
case may be, in form satisfactory to the Agent(s), of the same tenor as the
letter referred to in Section 5(d) hereof but modified to relate to the

SECTION 8. INDEMNIFICATION.

      (a) INDEMNIFICATION OF THE AGENTS. The Operating Partnership agrees to
indemnify and hold harmless each Agent and each person, if any, who controls
such Agent 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 an 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 an untrue
      statement or alleged untrue statement of a material fact included in any
      preliminary prospectus or the Prospectus (or any amendment or supplement
      thereto), or the omission or alleged omission therefrom of a material fact
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading;

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

            (iii) against any and all expense whatsoever, as incurred (including
      the fees and disbursements of counsel chosen by such Agent), reasonably
      incurred in investigating, preparing or defending against any litigation,
      or any investigation or proceeding by any governmental agency or body,
      commenced or threatened, or any claim whatsoever based upon any such
      untrue statement or omission, or any such alleged untrue statement or
      omission, to the extent that any such expense is not paid under
      subparagraph (i) or (ii) above;

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

            (b) INDEMNIFICATION OF OPERATING PARTNERSHIP, DIRECTORS AND
OFFICERS. Each Agent severally agrees to indemnify and hold harmless the
Operating Partnership, the directors of the Company, each of the officers who
signed the Registration Statement and each person, if any, who controls the
Operating Partnership within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act against any and all loss, liability, claim, damage
and expense described in the indemnity contained in Section 8(a) hereof, as
incurred, but only with respect to untrue


                                       21
<Page>

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 Operating Partnership by
the Agents expressly for use in the Registration Statement (or any amendment
thereto) or such preliminary prospectus or the Prospectus (or any amendment or
supplement thereto).

            (c) ACTIONS AGAINST PARTIES; NOTIFICATION. Each indemnified party
shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it is
not materially prejudiced as a result thereof and in any event shall not relieve
it from any liability which it may have otherwise than on account of this
indemnity agreement. In the case of parties indemnified pursuant to Section 8(a)
hereof, counsel to the indemnified parties shall be selected by the applicable
Agent(s) and, in the case of parties indemnified pursuant to Section 8(b)
hereof, counsel to the indemnified shall be selected by the Operating
Partnership. An indemnifying party may participate at its own expense in the
defense of any such action; PROVIDED, HOWEVER, that counsel to the indemnifying
party shall not (except with the consent of the indemnified party) also be
counsel to the indemnified party. In no event shall the indemnifying parties be
liable for fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.

      No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 8 or 9 hereof (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

      (d) SETTLEMENT WITHOUT CONSENT IF FAILURE TO REIMBURSE. If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 8(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 9. CONTRIBUTION. If the indemnification provided for in
Section 8 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of


                                       22
<Page>

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 Operating Partnership, on the one hand, and the
applicable Agent(s), on the other hand, from the offering of the Notes that were
the subject of the claim for indemnification 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 Operating Partnership, on the one hand,
and the applicable Agent(s), 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 Operating Partnership, on the
one hand, and the applicable Agent(s), on the other hand, in connection with the
offering of the Notes that were the subject of the claim for indemnification
shall be deemed to be in the same respective proportions as the total net
proceeds from the offering of such Notes (before deducting expenses) received by
the Operating Partnership and the total discount or commission received by each
applicable Agent, as the case may be, bears to the aggregate initial offering
price of such Notes.

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

            The Operating Partnership and the Agents agree that it would not be
just and equitable if contribution pursuant to this Section 9 were determined by
pro rata allocation (even if the applicable Agent(s) 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 9. The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 9 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 applicable untrue or alleged
untrue statement or omission or alleged omission.

            Notwithstanding the provisions of this Section 9, (i) no Agent shall
be required to contribute any amount in excess of the amount by which the total
discount or commission received by such Agent in connection with the offering of
the Notes that were the subject of the claim for indemnification exceeds the
amount of any damages which such Agent has otherwise been required to pay by
reason of any applicable untrue or alleged untrue statement or omission or
alleged omission and (ii) 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. In addition, in connection with an offering of Notes
purchased from


                                       23
<Page>

the Operating Partnership by two or more Agents as principal, the respective
obligations of such Agents to contribute pursuant to this Section 9 are several,
and not joint, in proportion to the aggregate principal amount of Notes that
each such Agent has agreed to purchase from the Operating Partnership.

            For purposes of this Section 9, each person, if any, who controls an
Agent 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 Agent, and each director
of the Operating Partnership, each officer of the Operating Partnership and each
person, if any, who controls the Operating Partnership within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Operating Partnership.

SECTION 10. PAYMENT OF EXPENSES.

      The Operating Partnership will pay all expenses incident to the
performance of its obligations under this Agreement, including:

      (a) The preparation, filing, printing and delivery of the Registration
Statement as originally filed and all amendments thereto and any preliminary
prospectus, the Prospectus and any amendments or supplements thereto;

      (b) The preparation, printing and delivery of this Agreement and the
Indenture;

      (c) The preparation, issuance and delivery of the Notes, including any
fees and expenses relating to the eligibility and issuance of Notes in
book-entry form and the cost of obtaining CUSIP or other identification numbers
for the Notes;

      (d) The fees and disbursements of the Operating Partnership's accountants,
counsel and other advisors or agents (including any calculation agent or
exchange rate agent) and of the Trustee and its counsel;

      (e) The reasonable fees and disbursements of counsel to the Agents
incurred in connection with the establishment of the Program and incurred from
time to time in connection with the transactions contemplated hereby;

      (f) The fees charged by nationally recognized statistical rating
organizations for the rating of the Program and the Notes;

      (g) The fees and expenses incurred in connection with any listing of Notes
on a securities exchange;

      (h) The filing fees incident to, and the reasonable fees and disbursements
of counsel to the Agents in connection with, the review, if any, by the National
Association of Securities Dealers, Inc. (the "NASD"); and


                                       24
<Page>

      (i) Any advertising and other out-of-pocket expenses of the Agents
incurred with the approval of the Operating Partnership.

SECTION 11. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY.

      All representations, warranties and agreements contained in this Agreement
or in certificates of officers of the Company, the Operating Partnership or any
of its subsidiaries submitted pursuant hereto or thereto shall remain operative
and in full force and effect, regardless of any investigation made by or on
behalf of the Agents or any controlling person of an Agent, or by or on behalf
of the Operating Partnership, and shall survive each delivery of and payment for
the Notes.

SECTION 12. TERMINATION.

      (a) TERMINATION OF THIS AGREEMENT. This Agreement (excluding any agreement
by one or more Agents to purchase Notes from the Operating Partnership as
principal) may be terminated for any reason, at any time by either the Operating
Partnership or an Agent, as to itself, upon the giving of 30 days' prior written
notice of such termination to the other party hereto.

      (b) TERMINATION OF AGREEMENT TO PURCHASE NOTES AS PRINCIPAL. The
applicable Agent(s) may terminate any agreement by such Agent(s) to purchase
Notes from the Operating Partnership as principal, immediately upon notice to
the Operating Partnership, at any time prior to the Settlement Date relating
thereto, if (i) there has been, since the date of such agreement or since the
respective dates as of which information is given in the Prospectus, any
material adverse change in the condition, financial or otherwise, or in the
earnings, business affairs or business prospects of the Operating Partnership
and its subsidiaries considered as one enterprise, whether or not arising in the
ordinary course of business, or (ii) there has occurred any material adverse
change in the financial markets in the United States or, if such Notes are
denominated and/or payable in, or indexed to, one or more foreign or composite
currencies, in the international financial markets, or any outbreak of
hostilities or escalation thereof or other calamity or crisis or any change or
development or event involving a prospective change in national or international
political, financial or economic conditions, in each case the effect of which is
such as to make it, in the judgment of such Agent(s), impracticable to market
such Notes or enforce contracts for the sale of such Notes, or (iii) trading in
any securities of the Company or the Operating Partnership has been suspended or
materially limited by the Commission or a national securities exchange, or if
trading generally on the New York Stock Exchange or the American Stock Exchange
or in the Nasdaq National Market has been suspended or materially limited, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices have been required, by either of said exchanges or by such system or by
order of the Commission, the NASD or any other governmental authority, or (iv) a
banking moratorium has been declared by either Federal or New York authorities
or by the relevant authorities in the country or countries of origin of any
foreign or composite currency in which such Notes are denominated and/or
payable, or (v) the rating assigned by any nationally recognized statistical
rating organization to the Program or any debt securities (including the Notes)
of the Operating Partnership as of the date of such agreement shall have been
lowered or withdrawn since that date or if any such rating organization shall
have publicly announced that it has under surveillance or review its rating of
the Program or any such debt securities, or (vi) there shall have come to the


                                       25
<Page>

attention of such Agent(s) any facts that would cause such Agent(s) to believe
that the Prospectus, at the time it was required to be delivered to a purchaser
of such Notes, included an untrue statement of a material fact or omitted to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances existing at the time of such delivery, not
misleading.

      (c) GENERAL. In the event of any such termination, neither party will have
any liability to the other party hereto, except that (i) the Agents shall be
entitled to any commissions earned in accordance with the third paragraph of
Section 3(b) hereof, (ii) if at the time of termination (a) any Agent shall own
any Notes purchased by it from the Operating Partnership as principal or (b) an
offer to purchase any of the Notes has been accepted by the Operating
Partnership but the time of delivery to the purchaser or his agent of such Notes
relating thereto has not occurred, the covenants set forth in Sections 4 and 7
hereof shall remain in effect until such Notes are so resold or delivered, as
the case may be, and (iii) the covenant set forth in Section 4(i) hereof, the
provisions of Section 10 hereof, the indemnity and contribution agreements set
forth in Sections 8 and 9 hereof, and the provisions of Sections 11, 14 and 15
hereof shall remain in effect.

                      FORM OF OPINION OF COMPANY'S COUNSEL
                   TO BE DELIVERED PURSUANT TO SECTION 5(b)(1)

      (1) The Company is a corporation duly organized and validly existing under
the laws of the State of Indiana. The Operating Partnership is a limited
partnership duly organized and validly existing under the laws of the State of
Indiana.

      (2) The Operating Partnership has partnership power and authority to own,
lease and operate its properties and to conduct its business as described in the
Prospectus and to enter into the Distribution Agreement and consummate the
transactions contemplated in the Prospectus.

      (3) The Operating Partnership is duly qualified as a foreign partnership
to transact business and is in good standing 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 or
be in good standing would not result in a Material Adverse Effect.

      (4) All of the issued and outstanding Units have been duly authorized and
are validly issued, fully paid and non-assessable, except as provided under
Indiana Code ss. 16-7-7; and none of the outstanding Units were issued in
violation of preemptive or other similar rights of any securityholder of the
Operating Partnership.

      (5) Each Significant Subsidiary has been duly organized and is validly
existing as a corporation, partnership or limited liability company in good

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

      (7) The Indenture has been duly authorized, executed and delivered by the
Operating Partnership and (assuming due authorization, execution and delivery
thereof by the applicable Trustee) constitutes a valid and legally binding
agreement of the Operating Partnership,


                                      B-1
<Page>

enforceable against the Operating Partnership in accordance with its terms,
except as the enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally or by general equitable principles (regardless of
whether enforcement is considered in a proceeding in equity or at law), and
except further as enforcement thereof may be limited by requirements that a
claim with respect to any debt securities issued under the Indenture that are
payable in a foreign or composite currency (or a foreign or composite currency
judgment in respect of such claim) be converted into U.S. dollars at a rate of
exchange prevailing on a date determined pursuant to applicable law or by
governmental authority to limit, delay or prohibit the making of payments
outside the United States.

      (8) The Notes have been duly authorized by the Operating Partnership for
offer, sale, issuance and delivery pursuant to the Distribution Agreement and,
when issued, authenticated and delivered in the manner provided for in the
Indenture and delivered against payment of the consideration therefor, will
constitute valid and legally binding obligations of the Operating Partnership,
enforceable against the Operating Partnership in accordance with their terms,
except as the enforcement thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally or by general equitable principles (regardless of
whether enforcement is considered in a proceeding in equity or at law), and
except further as enforcement thereof may be limited by requirements that a
claim with respect to any Notes payable in a foreign or composite currency (or a
foreign or composite currency judgment in respect of such claim) be converted
into U.S. dollars at a rate of exchange prevailing on a date determined pursuant
to applicable law or by governmental authority to limit, delay or prohibit the
making of payments outside the United States; and the Notes, in the forms
certified on the date hereof, are in the form contemplated by, and each
registered holder thereof is entitled to the benefits of, the Indenture.

      (9) The Indenture and the Notes, in the forms certified on the date
hereof, conform in all material respects to the statements relating thereto
contained in the Prospectus and are in substantially the form filed or
incorporated by reference, as the case may be, as an exhibit to the Registration
Statement.

      (10) The information in the Prospectus under "Description of Debt
Securities", "Description of the Notes", "Risk Factors " and "Certain United
States Federal Income Tax Considerations," and the information in the
Registration Statement under Item 15, to the extent that such information
constitutes matters of law, summaries of legal matters, the Operating
Partnership's partnership agreement or legal proceedings, or legal conclusions,
has been reviewed by us and is correct in all material respects.

      (11) To the best of our knowledge, none of the entities comprising the
Duke Group is in violation of its charter, by-laws, certificate of limited
partnership, partnership agreement, articles of organization or operating
agreement, and no default by a member of the Duke Group exists in the due
performance or observance of any material obligation, agreement, covenant or
condition contained in any Agreement and Instrument that is described or
referred to in the Registration Statement or the Prospectus or filed or
incorporated by reference as an exhibit to the Registration Statement.

      (12) The execution, delivery and performance of the Distribution
Agreement, the Indenture and the Notes and any other agreement or instrument
entered into or issued or to be


                                      B-2
<Page>

entered into or issued by the Operating Partnership in connection with the
transactions contemplated in the Prospectus, the consummation of the
transactions contemplated in the Prospectus (including the issuance and sale of
the Notes and the use of the proceeds therefrom as described in the Prospectus)
and the compliance by the Operating Partnership with its obligations thereunder
have been duly authorized by all necessary partnership action and do not and
will not, whether with or without the giving of notice or passage of time or
both, conflict with or constitute a breach of, or default or repayment event
under, or result in the creation or imposition of any lien, charge or
encumbrance upon any assets, properties or operations of the Duke Group pursuant
to, any Agreement and Instrument known to us, nor will such action result in any
violation of the provisions of the partnership agreement or other organizational
documents of a member of the Duke Group or any applicable law, statute, rule,
regulation, judgment, order, writ or decree, known to us, of any government,
government instrumentality or court, domestic or foreign, having jurisdiction
over any member of the Duke Group or any of their assets, properties or
operations.

      (13) To the best of our knowledge, there is not pending or threatened any
action, suit, proceeding, inquiry or investigation to which any member of the
Duke Group is a party or to which the assets, properties or operations of any
member of the Duke Group is subject, before or brought by any court or
governmental agency or body, domestic or foreign, which might reasonably be
expected to result in a Material Adverse Effect or which might reasonably be
expected to materially and adversely affect the assets, properties or operations
of the Duke Group or any of its subsidiaries, the performance by the Operating
Partnership of its obligations under the Distribution Agreement, the Indenture
or the Notes or the consummation of the transactions contemplated in the
Prospectus.

      (14) All descriptions in the Prospectus of contracts and other documents
to which any member of the Duke Group is a party are accurate in all material
respects; and, to the best of our knowledge, there are no franchises, contracts,
indentures, mortgages, loan agreements, notes, leases or other instruments
required to be described or referred to in the Registration Statement or to be
filed as exhibits to the Registration Statement other than those described or
referred to therein or filed or incorporated by reference as exhibits thereto,
and the descriptions thereof or references thereto are correct in all material
respects.

      (15) To the best of our knowledge, there are no statutes or regulations
that are required to be described in the Prospectus that are not described as
required.

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

      (17) The Registration Statement and the Prospectus, excluding the
documents incorporated by reference therein, and each amendment or supplement to
the Registration Statement and Prospectus, excluding the documents incorporated
by reference therein, as of their respective effective or issue dates (other
than the financial statements and supporting schedules included therein or
omitted therefrom and the Trustee's Statement of Eligibility on Form T-1 (the
"Form T-1"), as to which we express no opinion), complied as to form in all
material respects


                                      B-3
<Page>

with the requirements of the 1933 Act and the 1933 Act Regulations.

      (18) The documents incorporated by reference in the Prospectus (other than
the financial statements and supporting schedules included therein or omitted
therefrom, as to which we express no opinion), when they were filed with the
Commission, complied as to form in all material respects with the requirements
of the 1934 Act and the 1934 Act Regulations.

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

      (20) The Operating Partnership is not, and upon the issuance and sale of
the Notes and the application of the net proceeds therefrom as described in the
Prospectus will not be, an "investment company" within the meaning of the 1940
Act.

      (21) The Notes, in the forms certified on the date hereof, will be
excluded or exempted under, or beyond the purview of, the Commodity Exchange Act
and the Commodity Exchange Act Regulations.

      (22) No filing with, or approval, authorization, consent, license,
registration, qualification, order or decree of, any court or governmental
authority or agency, domestic or foreign, is necessary or required for the due
authorization, execution and delivery by the Operating Partnership of the
Distribution Agreement, the Indenture and the Notes or for the performance by
the Operating Partnership of the transactions contemplated in the Distribution
Agreement, the Indenture or the Prospectus, except such as have been previously
made, obtained or rendered, as applicable.

      (23) Assuming the Company was organized in conformity with and has
satisfied the requirements for qualification and taxation as a "real estate
investment trust" under the Code for each of its taxable years from and
including the first taxable year for which the Company made the election to be
taxed as a "real estate investment trust" through the 1993 taxable year, the
proposed methods of operation of the Company, the Operating Partnership and the
Services Partnership since and including 1994, as described in the Registration
Statement and the Prospectus Supplement and as represented by the Company, the
Operating Partnership and the Services Partnership has permitted and will permit
the Company to qualify and to continue to qualify to be taxed as a "real estate
investment trust" for all years since and including 1994 and for its current and
subsequent taxable years.

      Nothing has come to our attention that would lead us to believe that the
Registration Statement or any post-effective amendment thereto (except for
financial statements, supporting schedules and other financial data included
therein or omitted therefrom and for the Form T-1, as to which we make no
statement), at the time the Registration Statement or any post-effective
amendment thereto (including the filing of the Operating Partnership's Annual
Report on Form 10-K with the Commission) became effective [or at the date of any
agreement of the applicable Agent(s) to purchase Notes from the Operating
Partnership as principal], contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Prospectus or any
amendment or supplement thereto (except for financial statements, supporting
schedules and other financial data included therein or omitted therefrom, as to
which we make no statement), at the time the Prospectus was issued, at the time
any such amended or supplemented prospectus was issued or at the date hereof,
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


                                      B-4

circumstances under which they were made, not misleading.

333-37920) on Form S-3 filed by the Company under the Act; our report with
respect thereto is also incorporated by reference in that registration
statement. The registration statement, as amended on June 13, 2000, includes the
prospectus dated June 13, 2000, prospectus supplements dated January 29, 2001,
February 28, 2001 and June 5, 2001, and other filings incorporated by reference
through the date of this letter, and is herein referred to as the Registration
Statement.

In connection with the Registration Statement:

1.    We are independent certified public accountants with respect to the
      Company and the Operating Partnership within the meaning of the Act and
      the applicable rules and regulations thereunder adopted by the Securities
      and Exchange Commission (the SEC).

2.    In our opinion, the consolidated financial statements and financial
      statement schedule of the Company and the Operating Partnership audited by
      us and incorporated by reference in the Registration Statement comply as
      to form in all material respects with the applicable accounting
      requirements of the Act and the Securities Exchange Act of 1934 and the
      related rules and regulations adopted by the SEC.

3.    We have not audited any financial statements of the Company or the
      Operating Partnership as of any date or for any period subsequent to
      December 31, 2000; although we have conducted audits for the year ended
      December 31, 2000, the purpose (and therefore the scope) of the audits
      were to enable us to express an opinion on the consolidated financial
      statements of the Company and the Operating Partnership as of December 31,
      2000 and for the year then ended, but not on the consolidated financial
      statements for any interim period within that year. Therefore, we are
      unable to and do not express any opinion on the March 31, 2001 and 2000
      unaudited condensed consolidated financial statements of the Company
      included in the Company's quarterly report on Form 10-Q for the quarter
      ended March 31, 2001, incorporated by reference in the Registration
      Statement, or on the financial position, results of operations, or cash
      flows of the Company as of any date or for any period subsequent to
      December 31, 2000. We are also unable to and do not express any opinion on
      the March 31, 2001 and 2000 unaudited condensed consolidated financial
      statements of the Operating Partnership included in the Operating
      Partnership's quarterly report on Form 10-Q for the quarter ended March
      31, 2001, incorporated by reference in the Registration Statement, or on
      the financial position, results of operations, or cash flows of the
      Operating Partnership as of any date or for any period subsequent to
      December 31, 2000.

4.    For purposes of this letter, we have read the 2001 minutes of meetings of
      the Board of Directors of the Company and its subsidiaries as set forth in
      the minute books at June 5, 2001 (minutes of the Company's April meetings
      of the Board of Directors and its committees were not available),
      officials of the Company having advised us that the minutes of all such
      meetings through that date were set forth therein, with the exception of
      the April meetings. We have also been advised that there were no minutes
      of meetings related to the Operating Partnership. We have carried out
      other procedures to June 5, 2001 as follows (our work did not extend to
      the period from June 6, 2001 to June 8, 2001, inclusive):

      a.    With respect to the three-month periods ended March 31, 2001 and
            2000, we have--

            (i)   Performed the procedures specified by the American Institute
                  of Certified Public Accountants for a review of interim
                  financial information as described in SAS No. 71, INTERIM
                  FINANCIAL INFORMATION, on the unaudited condensed consolidated
                  financial statements for these periods included in the
                  Company's quarterly report on Form 10-Q for the quarter ended
                  March 31, 2001 and the Operating Partnership's quarterly
                  report on Form 10-Q for the quarter ended March 31, 2001,
                  incorporated by reference in the Registration Statement.

            (ii)  Inquired of certain officials of the Company who have
                  responsibility for financial and accounting matters whether
                  the unaudited condensed consolidated financial statements
                  referred to in 4a(I) comply as to form in all material
                  respects with the applicable accounting requirements of the
                  Securities Exchange Act of 1934 as it applies to Form 10-Q and
                  the related rules and regulations adopted by the SEC.

      b.    With respect to the period from April 1, 2001 to April 30, 2001, we
            have:

            (i)   Read the incomplete unaudited condensed consolidated financial
                  statements of the Company and the Operating Partnership for
                  April of both 2001 and 2000 furnished to us by the Company
                  (incomplete in that the financial statements omit the
                  statements of cash flows and all disclosures as required by
                  accounting principles generally accepted in the United States
                  of America), officials of the Company having advised us that
                  no such financial statements as of any date or for any period
                  subsequent to April 30, 2001 were available.

            (ii)  Inquired of certain officials of the Company who have
                  responsibility for financial and accounting matters whether
                  the incomplete unaudited condensed consolidated financial
                  statements referred to in 4b(I) are stated on a basis
                  substantially consistent with that of the audited consolidated
                  financial statements of the Company and the Operating
                  Partnership incorporated by reference in the Registration
                  Statement.

      The foregoing procedures do not constitute an audit conducted in
      accordance with auditing standards generally accepted in the United States
      of America. Also, they would not necessarily reveal matters of
      significance with respect to the comments in the following paragraph.
      Accordingly, we make no representations about the sufficiency of the
      foregoing procedures for your purposes.

5.    Nothing came to our attention as a result of the foregoing procedures,
      however, that caused us to believe that--

      a.    (i)   Any material modifications should be made to the unaudited
                  condensed consolidated financial statements described in
                  4a(i), incorporated by reference in the Registration
                  Statement, for them to be in conformity with accounting
                  principles generally accepted in the United States of America.


                                      C-2

            (ii)  The unaudited condensed consolidated financial statements
                  described in 4a(i) do not comply as to form in all material
                  respects with the applicable accounting requirements of the
                  Securities Exchange Act of 1934 as it applies to Form 10-Q and
                  the related rules and regulations adopted by the SEC.

      b.    (i)   At April 30, 2001, there was any change in capital stock or
                  partners' units, increase in debt, or decrease in
                  shareholders' or partners' equity of the Company or the
                  Operating Partnership as compared with the amounts shown in
                  the March 31, 2001 unaudited condensed consolidated balance
                  sheets of the Company or the Operating Partnership, both
                  incorporated by reference in the registration statement, or
                  (ii) for the period from April 1, 2001 to April 30, 2001,
                  there were any decreases, as compared with the corresponding
                  period of the previous year, in revenues, net income or Funds
                  From Operations (as defined in the registration statement) of
                  the Company or the Operating Partnership, except for the
                  effects of the Company's quarterly dividends to its
                  shareholders and the Operating Partnership's quarterly
                  distributions to its partners, the issuance of 48,483 common
                  shares and 64,696 common units, an increase in debt of
                  approximately $131 million resulting from the assumption of
                  $107 million of mortgage notes, mortgage note payments of $6
                  million and borrowings of $30 million on the Company's lines
                  of credit, and except in all instances for changes, increases
                  or decreases that the registration statement discloses have
                  occurred or may occur.

6.    As mentioned in 4b, officials of the Company have advised us that no
      consolidated financial statements as of any date or for any period
      subsequent to April 30, 2001 are available; accordingly, the procedures
      carried out by us with respect to changes in financial statement items
      after April 30, 2001 have, of necessity, been even more limited than those
      with respect to the periods referred to in 4. We have made inquiries of
      certain officials of the Company who have responsibility for financial and
      accounting matters regarding whether (A) at June 5, 2001, there was any
      change in the capital stock or partners' units, increase in debt, or
      decrease in shareholders' or partners' equity of the consolidated
      companies as compared with amounts shown in the March 31, 2001 unaudited
      condensed consolidated balance sheets of the Company or the Operating
      Partnership, both incorporated by reference in the Registration Statement
      or (B) for the period from April 1, 2001 to June 5, 2001, there were any
      decreases, as compared with the corresponding period in the preceding
      year, in revenues, net income or Funds From Operations (as defined in the
      Registration Statement) of the Company and its subsidiaries or the
      Operating Partnership and its subsidiaries. On the basis of these
      inquiries and our reading of the minutes as described in 4, nothing came
      to our attention that caused us to believe that there was any such change,
      increase or decrease, except for the issuance of 233,377 common shares and
      99,788 partner units and the effects of the Company's quarterly dividends
      to its shareholders and the Operating Partnership's quarterly distribution
      to its partners, and except in all instances for changes, increases or
      decreases that the Registration Statement discloses have occurred or may
      occur.

7.    This letter is solely for the information of the addressees and to assist
      the underwriters in conducting and documenting their investigation of the
      affairs of the Company and the Operating Partnership in connection with
      the offering of the securities covered by the Registration Statement, and
      it is not to be used, circulated, quoted or otherwise referred to within
      or without the underwriting group for any purpose, including but not
      limited to, the registration, purchase or sale of securities, nor is it to
      be filed with or referred to, in whole or in part in the Registration
      Statement or any other document, except that reference may be made to it
      in the distribution agreement or in any list of closing documents
      pertaining to the offering of the securities covered by the Registration
      Statement.
