1995 KEY EMPLOYEES' STOCK OPTION PLAN OF DUKE REALTY INVESTMENTS, INC. ARTICLE I INTRODUCTION 1.1. PURPOSE. The 1995 Key Employees' Stock Option Plan of Duke Realty Investments, Inc. (the "Plan") is designed to promote the interests of the Company and its Subsidiaries by encouraging their officers and key employees, upon whose judgment, initiative and industry the Company and its Subsidiaries are largely dependent for the successful conduct and growth of their businesses, to continue their association with the Company and its Subsidiaries by providing additional incentive and opportunity for unusual industry and efficiency through stock ownership, and by increasing their proprietary interest in the Company and their personal interest in its continued success and progress. The Plan provides for the granting of (i) incentive stock options ("ISO's") and (ii) nonqualified stock options ("NSO's"). 1.2. EFFECTIVE DATE AND DURATION. The Effective Date of the Plan is October 1, 1995. Options may be granted under the Plan for a period of ten (10) years commencing October 1, 1995; however, no options may be exercised until this Plan has been approved by a majority of the shares of the Company represented at the shareholders' meeting at which approval of the Plan is considered. No options shall be granted after September 30, 2005. Upon that date, the Plan shall expire except as to outstanding options, which options shall remain in effect until they have been exercised or terminated or have expired. ISO's must be granted within ten (10) years of the date the Plan is adopted by the Board of Directors or approved by the shareholders of the Company, whichever is earlier. 1.3. ADMINISTRATION. The Plan shall be administered by the Committee. The Committee, from time to time, may adopt any rule or procedure it deems necessary or desirable for the proper and efficient administration of the Plan provided it is consistent with the terms of the Plan. The decision of a majority of the Committee members shall constitute the decision of the Committee. Subject to the provisions of the Plan, the Committee is authorized (i) to grant ISO's and NSO's; (ii) to determine the employees to be granted ISO's and NSO's; (iii) to determine the option period, the option price and, subject to the limitations of Section 3.2, the number of shares subject to each option; (iv) to determine the time or times at which options will be granted; (v) to determine the time or times at which each option becomes exercisable and the duration of the exercise period; (vi) to determine other conditions and limitations, if any, applicable to the exercise of each option; and (vii) to determine the nature and duration of the restrictions, if any, to be imposed upon the sale or other disposition of shares acquired by any optionee upon exercise of an option, and the nature of the events, if any, and the duration of the period, in or with respect to which any optionee's rights to shares acquired upon exercise of an option may be forfeited. Each option granted under the Plan shall be evidenced by a written stock option agreement containing terms and conditions established by the Committee consistent with the provisions of the Plan, including such terms as the Committee shall deem advisable in order that each ISO shall constitute an "incentive stock option" within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). The Committee's determinations and interpretations with respect to the Plan shall be final and binding on all parties. Any notice or document required to be given to or filed with the Committee will be properly given or filed if delivered or mailed by certified mail, postage prepaid, to the Committee at 8888 Keystone Crossing, Suite 1200, Indianapolis, Indiana 46240-2182. 1.4.

Shares covered by an option that remains unpurchased upon the expiration or termination of the option may be made subject to further options. 3.2. GRANT OF OPTIONS. The Committee shall be responsible for granting all options under the Plan. The Committee shall also determine, in its sole discretion, with respect to each optionee, whether the options granted shall be ISO's or NSO's, or a combination of the two; and whether any employee shall be given discretion to determine whether any options granted to him shall be ISO's or NSO's or a combination of the two.

SEQUENCE OF EXERCISING INCENTIVE STOCK OPTIONS. Any ISO granted to an employee pursuant to the Plan shall be exercisable even if there are outstanding previously granted but unexercised ISO's with respect to such employee. 3.7 VESTING OF OPTIONS. All options granted under the Plan shall vest, and thereby become exercisable at such time or times as shall be determined by the Committee in its sole discretion. The stock option agreement between the Company and the optionee shall include the schedule under which the option shall vest. 3.8 VESTING ON CHANGE IN CONTROL OR DEATH, RETIREMENT OR DISABILITY OF OPTIONEE. Notwithstanding the provisions of Section 3.7, in the event of a Change in Control of the Company or upon the death, Permanent and Total Disability or retirement on or after attaining age sixty-five (65) of the optionee, any options granted under this Plan may be exercised in full without regard to any restrictions on the vesting of the options contained in the option agreement between the Company and the optionee. 3.9. EARLY TERMINATION OF OPTION. (a) TERMINATION OF EMPLOYMENT. All rights to exercise an option shall terminate ninety (90) days after the effective date of the optionee's termination of employment with the Company and its Subsidiaries, but not later than the date the option expires pursuant to its terms, unless such termination is For Cause or is on account of the Permanent and Total Disability or death of the optionee. Transfer of employment from the Company to a Subsidiary, or vice versa, or from one Subsidiary to another, shall not be deemed a termination of employment. The Committee shall have the authority to determine in each case whether a leave of absence on military or government service shall be deemed a termination of employment for purposes of this subsection (a). (b) FOR CAUSE TERMINATION. If an optionee's employment with the Company and its Subsidiaries is terminated For Cause, no previously unexercised option granted hereunder -5- may be exercised. Rather, all unexercised options shall terminate effective on the date the optionee receives notice of his termination For Cause. (c) PERMANENT AND TOTAL DISABILITY OR DEATH OF OPTIONEE. If an optionee's employment terminates due to Permanent and Total Disability or death, his option shall terminate one (1) year after termination of his employment due to his Permanent and Total Disability or death (but not later than the date the option expires pursuant to its terms). During such period, subject to the limitations of this Plan and the option agreement between the Company and the optionee, the optionee, his guardian, attorney-in-fact or personal representative, as the case may be, may exercise the option in full. Notwithstanding the foregoing, in the case of an ISO, such option shall be exercisable as an ISO only during the three (3) month period immediately following the optionee's death and in no event later than the date specified in the stock option agreement. During the remainder of such one (1) year period, the option may be exercised as an NSO. 3.10. PAYMENT FOR STOCK. Full payment for shares purchased hereunder shall be made at the time the option is exercised. Payment may be made by delivering to the Company (a) cash; (b) at the discretion of the Committee, whole shares of common stock of the Company ("Delivered Stock") which (i) has been owned by the optionee for more than six (6) months and has been paid for, within the meaning of SEC Rule 144 (and, if such stock was purchased from the Company by use of a promissory note, such note has been fully paid with respect to such stock), or (ii) was obtained by the optionee in the public market or otherwise than through the exercise of an option under this Plan or under any other stock option plan involving Company stock; (c) at the discretion of the Committee, a combination of cash and Delivered Stock; or (d) provided that a public market for the Company's common stock exists, (i) through a "same day sale" commitment from the optionee and a broker-dealer that is a member of the National Association of Securities Dealers ("NASD Dealer") whereby the optionee irrevocably elects to exercise the option and to sell a portion of the common stock so purchased in order to pay the option price, and whereby the NASD Dealer irrevocably commits upon receipt of such stock to forward the option price directly to the Company; or (ii) through a "margin" commitment from the optionee and an NASD Dealer whereby the optionee irrevocably elects to exercise the option and to pledge the stock so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the option price and whereby the NASD Dealer irrevocably commits upon receipt of such stock to forward the option price directly to the Company. Delivered Stock shall be valued by the Committee at its Fair Market Value determined as of the date of the exercise of the option. No shares shall be issued until full payment for them has been made, and an optionee shall have none of the rights of a shareholder with respect to any shares until they are issued to him. Upon payment of the full purchase price, and any required withholding taxes, the Company shall issue a certificate or certificates to the optionee evidencing ownership of the shares purchased pursuant to the exercise of the option which contain(s) such terms, conditions and provisions as may be required and as are consistent with the terms, conditions and provisions of the Plan and the stock option agreement between the Company and the optionee. -6- 3.11. INCOME AND EMPLOYMENT TAX WITHHOLDING. (a) PAYMENT BY OPTIONEE. The optionee shall be solely responsible for paying to the Company all required federal, state, city and local taxes applicable to his (i) exercise of an NSO under the Plan and (ii) disposition of shares acquired pursuant to the exercise of an ISO in a disqualifying disposition of the shares under Code Section 422(a)(1). (b) NSO WITHHOLDING WITH COMPANY STOCK. Notwithstanding the provisions of subsection (a), with respect to stock to be issued pursuant to the exercise of an NSO, the Committee, in its discretion and subject to such rules as it may adopt, may permit the optionee to satisfy, in whole or in part, any withholding tax obligation which may arise in connection with the exercise of the NSO by having the Company retain shares of stock which would otherwise be issued in connection with the exercise of the NSO or accept delivery from the optionee of shares of Company stock which have a Fair Market Value, determined as of the date of the delivery of such shares, equal to the amount of the withholding tax to be satisfied by that retention or delivery. (c) ISO DISQUALIFYING DISPOSITION WITHHOLDING WITH COMPANY STOCK. Notwithstanding the provisions of subsection (a), with respect to shares of stock to be issued pursuant to the exercise of any ISO, the Committee, in its discretion and subject to such rules as it may adopt, may permit the optionee to satisfy, in whole or in part, any withholding tax obligation which may arise in connection with the disqualifying disposition of the shares under Code Section 422(a)(1) by having the Company accept delivery from the optionee of shares of stock having a Fair Market Value, determined as of the date of the delivery of such shares, equal to the amount of the withholding tax to be satisfied by that delivery. 3.12. NOTICE OF DISQUALIFYING DISPOSITION. Any ISO granted hereunder shall require the optionee to notify the Committee of any disposition of any stock issued pursuant to the exercise of the ISO under the circumstances described in Section 421(b) of the Code (relating to certain disqualifying dispositions), within ten (10) days of such disposition. -7- ARTICLE IV PLAN ADMINISTRATION AND INTERPRETATION 4.1. AMENDMENT AND TERMINATION. The Board of Directors or the Committee may, at any time, without the approval of the stockholders of the Company (except as otherwise required by applicable law, rule or regulations, or listing requirements of any National Securities Exchange on which are listed any of the Company's equity securities, including without limitation any shareholder approval requirement of Rule 16b-3 or any successor safe harbor rule promulgated under the Exchange Act ), alter, amend, modify, suspend or discontinue the Plan, but may not, without the consent of the holder of an option, make any alteration which would adversely affect an option previously granted under the Plan or, without the approval of the stockholders of the Company, make any alteration which would: (a) increase the aggregate number of shares subject to options under the Plan, except as provided in Section 4.2; (b) decrease the minimum option price, except as provided in Section 4.2; (c) permit any Committee member to become eligible to receive grants of options under the Plan; (d) withdraw administration of the Plan from the Committee or the Board of Directors; (e) extend the term of the Plan or the maximum period during which any option may be exercised; (f) change the manner of determining the option price; or (g) change the class of individuals eligible for options under the Plan. 4.2. CHANGES IN STOCK. (a) SUBSTITUTION OF STOCK AND ASSUMPTION OF PLAN. In the event of any change in the common stock of the Company through stock dividends, split- ups, recapitalizations, reclassifications, conversions, or otherwise, or in the event that other stock shall be converted into or substituted for the present common stock of the Company as the result of any merger, consolidation, reorganization or similar transaction which results in a Change in Control of the Company, then the Committee may make appropriate adjustment or substitution in the aggregate number, price, and kind of shares available under the Plan and in the number, price and kind of shares covered under any options granted or to be granted under the Plan. The Committee's determination in this respect shall be final and conclusive. Provided, however, that the Company shall not, and shall not permit its Subsidiaries to, recommend, facilitate or agree or consent to a transaction or series of transactions which would result in a Change of Control of the Company unless and until the person or persons or the entity or entities acquiring or succeeding to the assets or capital stock of the Company or any of its Subsidiaries as a result of such transaction or transactions agrees to be bound by the terms of the Plan so far as it pertains to options theretofore granted but unexercised and agrees to assume and perform the obligations of the Company hereunder. Notwithstanding the foregoing provisions of this subsection (a), no adjustment shall be made which would operate to reduce the option price of any ISO below the Fair Market Value of the stock (determined on the date the option was granted) which is subject to an ISO. (b) CONVERSION OF STOCK. In the event of a Change in Control of the Company pursuant to which another person or entity acquires control of the Company (such other person or entity being the "Successor"), the kind of shares of common stock which shall be subject to the -8- Plan and to each outstanding option, shall, automatically by virtue of such Change in Control of the Company, be converted into and replaced by shares of common stock, or such other class of securities having rights and preferences no less favorable than common stock of the Successor, and the number of shares subject to the option and the purchase price per share upon exercise of the option shall be correspondingly adjusted, so that, by virtue of such Change in Control of the Company, each optionee shall have the right to purchase (i) that number of shares of common stock of the Successor which have a Fair Market Value equal, as of the date of such Change in Control of the Company, to the Fair Market Value, as of the date of such Change in Control, of the shares of common stock of the Company theretofore subject to his option, and (ii) for a purchase price per share which, when multiplied by the number of shares of common stock of the Successor subject to the option, shall equal the aggregate exercise price at which the optionee could have acquired all of the shares of common stock of the Company previously optioned to the optionee. 4.3. INFORMATION TO BE FURNISHED BY OPTIONEES. Optionees, or any other persons entitled to benefits under this Plan, must furnish to the Committee such documents, evidence, data or other information as the Committee considers necessary or desirable for the purpose of administering the Plan. The benefits under the Plan for each optionee, and each other person who is entitled to benefits hereunder, are to be provided on the condition that he furnish full, true and complete data, evidence or other information, and that he will promptly sign any document reasonably related to the administration of the Plan requested by the Committee. 4.4. EMPLOYMENT RIGHTS. Neither the Plan nor any stock option agreement executed under the Plan shall constitute a contract of employment and participation in the Plan will not give an optionee the right to be rehired or retained in the employ of the Company, nor will participation in the Plan give any optionee any right or claim to any benefit under the Plan, unless such right or claim has specifically accrued under the terms of the Plan. 4.5. EVIDENCE. Evidence required of anyone under the Plan may be by certificate, affidavit, document or other information which the person relying thereon considers pertinent and reliable, and signed, made or presented by the proper party or parties. 4.6. GENDER AND NUMBER. Where the context admits, words in the masculine gender shall include the feminine gender, the plural shall include the singular and the singular shall include the plural. 4.7.

CONTROLLING LAWS. Except to the extent superseded by laws of the United States, the laws of Indiana shall be controlling in all matters relating to the Plan. -9- 4.9. MISTAKE OF FACT. Any mistake of fact or misstatement of fact shall be corrected when it becomes known and proper adjustment made by reason thereof. 4.10. SEVERABILITY. In the event any provisions of the Plan shall be held to be illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and endorsed as if such illegal or invalid provisions had never been contained in the Plan. 4.11. EFFECT OF HEADINGS. The descriptive headings of the sections of this Plan are inserted for convenience of reference and identification only and do not constitute a part of this Plan for purposes of interpretation. 4.12. NONTRANSFERABILITY. No option shall be transferable, except by the optionee's will or the laws of descent and distribution. During the optionee's lifetime, his option shall be exercisable (to the extent exercisable) only by him. The option and any rights and privileges pertaining thereto shall not be transferred, assigned, pledged or hypothecated by him in any way, whether by operation of law or otherwise and shall not be subject to execution, attachment or similar process. 4.13. LIABILITY. No member of the Board of Directors or the Committee or any officer or employee of the Company or its Subsidiaries shall be personally liable for any action, omission or determination made in good faith in connection with the Plan. Each optionee, in the stock option agreement between him and the Company, shall agree to release and hold harmless the Company, the Board of Directors, the Committee and all officers and employees of the Company and its Subsidiaries from and against any tax liability, including without limitation interest and penalties, incurred by the optionee in connection with his participation in the Plan. 4.14. INVESTMENT REPRESENTATIONS. Unless the shares subject to an option are registered under the Securities Act of 1933, each optionee, in the stock option agreement between the Company and the optionee, shall agree for himself and his legal representatives that any and all shares of common stock purchased upon the exercise of the option shall be acquired for investment and not with a view to, or for sale in connection with, any distribution of those shares. Any share issued pursuant to an exercise of an option subject to this investment representation shall bear a legend evidencing this restriction. -10- 4.15. USE OF PROCEEDS. The proceeds received by the Company from the sale of stock pursuant to the Plan will be used for general corporate purposes, including without limitation the purchase by the Company of additional limited partnership units in Duke Realty Limited Partnership.
