The Representatives Named in the Terms Agreement

Ladies and Gentlemen:

Duke Realty Corporation (the “Company”) may from time to time offer in one or more series (i) shares of Common Stock, $.01 par value (the “Common Stock”), (ii) shares of preferred stock, $.01 par value (the “Preferred Stock”) and (iii) shares of Preferred Stock represented by depositary shares (the “Depositary Shares”), with an aggregate public offering price of up to $400,748,000 (or its equivalent in another currency based on the exchange rate at the time of sale). Duke Realty Limited Partnership (the “Operating Partnership”) may from time to time offer in one or more series unsecured non-convertible investment grade debt securities (the “Debt Securities”), with an aggregate public offering price of up to $770,000,000 (or its equivalent in another currency based on the exchange rate at the time of sale). The Common Stock, Preferred Stock, Depositary Shares and Debt Securities (collectively, the “Securities”) may be offered, separately or together, in separate series, in amounts, at prices and on terms to be set forth in one or more Prospectus Supplements as hereinafter defined. The Debt Securities will be issued under one or more indentures, as amended or supplemented (each, an “Indenture”), between the Operating Partnership and a trustee (a “Trustee”). Each series of Debt Securities may vary, as applicable, as to aggregate principal amount, maturity date, interest rate or formula and timing of payments thereof, redemption or repayment provisions, and any other variable terms which the Indenture contemplates may be set forth in the Debt Securities as issued from time to time. As used herein, “the Representatives,” unless the context otherwise requires, shall mean the parties, identified in the applicable Terms Agreement (as hereinafter defined) as the Representatives with respect to Underwritten Securities (as hereinafter defined) purchased pursuant thereto.

Whenever the Company or the Operating Partnership determines to make an offering of Securities through the Representatives or through an underwriting syndicate managed by the Representatives, the Company or the Operating Partnership, as the case may be, will enter into an agreement (the “Terms Agreement”) providing for the sale of such Securities (the “Underwritten Securities”) to, and the purchase and offering thereof by, the Representatives and such other underwriters, if any, selected by the Representatives as have authorized the Representatives to enter into such Terms Agreement on their behalf (the “Underwriters,” which term shall include the Representatives whether acting alone in the sale of the Underwritten Securities or as a member of an underwriting syndicate and any Underwriter substituted pursuant to Section 10 hereof). In addition to specifying the names of the Representatives, the Terms Agreement relating to the offering of Underwritten Securities shall specify the amount of Underwritten Securities to be initially issued (the “Initial Securities”), the names of the Underwriters participating in such offering (subject to substitution as provided in Section 10 hereof), the amount of

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

The Company and the Operating Partnership have filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-108557) for the registration of the Securities under the Securities Act of 1933, as amended (the “1933 Act”), and the offering thereof from time to time in accordance with Rule 430A or Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”), and the Company and the Operating Partnership have filed such amendments thereto as may have been required prior to the execution of the applicable Terms Agreement. Such registration statement (as amended, if applicable) has been declared effective by the Commission and an Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “1939 Act”).

Any registration statement (including any supplement thereto or information which is deemed part thereof) filed by the Company or the Operating Partnership under Rule 462(b) of the 1933 Act Regulations (a “Rule 462(b) Registration Statement”) shall be deemed to be part of the Registration Statement. Any prospectus (including any amendment or supplement thereto or information which is deemed part thereof) included in the Rule 462(b) Registration Statement and any term sheet as contemplated by Rule 434 of the 1933 Act Regulations (a “Term Sheet”) shall be deemed to be part of the Prospectus.

SECTION 2. Sale and Delivery to Underwriters; Closing.

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

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

(c) Payment of the purchase price for, and delivery of certificates for, the Initial Underwritten Securities to be purchased by the Underwriters shall be made at the offices of Clifford

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

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

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

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

each of them, and the Company or the Operating Partnership, as the case may be, will advise the Representatives at least two business days prior to the applicable Closing Time, of the names of the institutions with which the making of Delayed Delivery Contracts is approved by the Company or the Operating Partnership, as the case may be, and the amount of Underwritten Securities to be covered by each such Delayed Delivery Contract.

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

SECTION 3. Covenants of the Company and the Operating Partnership. Each of the Company and the Operating Partnership covenants with the Representatives, and with each Underwriter participating in the offering of Underwritten Securities, as follows:

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

If required, the Company and the Operating Partnership will prepare and file or transmit for filing a Rule 462(b) Registration Statement not later than the date of execution of the Terms Agreement.

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

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

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

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

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

Operating Partnership, at any time at or prior to Closing Time, and such termination shall be without liability of any party to any other party except as provided in Section 4 hereof.

SECTION 6. Indemnification.

(a) Each of the Company and the Operating Partnership agrees, jointly and severally, to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, Prospectus, preliminary prospectus supplement or Prospectus Supplement (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto);

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever for which indemnification is provided under subsection (i) above if such settlement is effected with the written consent of the indemnifying party; and

(iii) against any and all expense whatsoever, as incurred (including, subject to Section 6(c) hereof, the fees and disbursements of counsel chosen by), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever for which indemnification is provided under subsection (i) above, to the extent that any such expense is not paid under (i) or (ii) above.

(b) Each Underwriter severally agrees to indemnify and hold harmless the Company and the Operating Partnership and each person, if any, who controls the Company and the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto) or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of any such action. If it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it and reasonably approved by the indemnified parties defendant in such action; provided, however, that if the defendants (including any impleaded parties) in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel) (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, (ii) the indemnifying party does not promptly retain counsel reasonably satisfactory to the indemnified party or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. The indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the consent of the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

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

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other hand, from the offering of the Underwritten Securities pursuant to the applicable Terms Agreement

or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Operating Partnership, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Underwritten Securities pursuant to the applicable Terms Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Underwritten Securities (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of such Underwritten Securities as set forth on such cover.

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

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

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

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or the Operating Partnership, as the case may be. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Underwritten Securities set forth opposite their respective names in the applicable Terms Agreement and not joint.

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

SECTION 9. Termination of Agreement.

(a) The Representatives may terminate the applicable Terms Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the date of such Terms Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change, affecting the Duke Group as a whole, in the condition, financial or otherwise, or in the earnings, assets, business affairs or business prospects of any entity belonging to the Duke Group or of any Property, whether or not arising in the ordinary course of business; or (ii) if there has occurred any material adverse change in the financial markets in the United States, or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic condition, in each case the effect of which is such as to make it, in judgement of the Representatives, impracticable or inadvisable to (x) commence or continue the offering of Underwritten Securities to the public, or (y) enforce contracts for the sale of the Underwritten Securities; or (iii) if trading in the Common Stock has been suspended by the Commission or if trading generally on either the New York Stock Exchange or the American Stock Exchange has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by either of said Exchanges or by order of the Commission or any other governmental authority, or if a banking moratorium has been declared by either Federal, New York or Indiana authorities, or if there has occurred a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) if Preferred Stock is being offered and the rating assigned by any nationally recognized statistical rating organization to any preferred shares of the Company as of the date of the applicable Terms Agreement shall have been lowered since such date or if any such rating organization shall have publicly announced that it has placed any preferred shares or debt securities of the Company on what is commonly termed a “watch list” for possible downgrading; or (v) if the rating assigned by any nationally recognized statistical rating organization to any long-term debt securities of the Operating Partnership as of the date of the applicable Terms Agreement shall have been lowered since such date or if any such rating organization shall have publicly announced that it has placed any long-term debt securities of the Operating Partnership on what is commonly termed a “watch list” for possible downgrading. As used in this Section 9(a), the term “Prospectus” means the Prospectus in the form first used to confirm sales of the Underwritten Securities.

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

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time to purchase the Underwritten Securities which it or they are obligated to purchase under the applicable Terms Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting

Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

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

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

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

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

SECTION 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives at the address specified in the applicable Terms Agreement; notices to the Company and the Operating Partnership shall be directed to any of them at 600 East 96^th Street, Suite 100, Indianapolis, Indiana, 46240, attention of Darell E. Zink, Jr.

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

SECTION 13. Governing Law and Time. This Agreement and the Terms Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and to be performed in said State. Specified times of day refer to New York City time.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company an executed counterpart of the applicable Terms Agreement, whereupon this instrument, along with the applicable Terms Agreement, will become a binding agreement among the Underwriters, the Company and the Operating Partnership in accordance with their terms.
