▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

Keystone Property Trust, a Maryland statutory real estate investment trust (including its predecessor, the “Company”), the persons listed on Schedule B hereto (the “▇▇▇▇▇▇ Selling Shareholders”) and the persons listed on Schedule C hereto (the “Pioneer Selling Shareholders” and, collectively with the ▇▇▇▇▇▇ Selling Shareholders, the “Selling Shareholders”), confirm their respective agreements with Citigroup Global Markets Inc. (the “Underwriter”), with respect to the sale by the Selling Shareholders, acting severally and not jointly, and the purchase by the Underwriter, of the respective numbers of common shares of beneficial interest, par value $.001 per share, of the Company (the “Common Shares”) set forth on (i) Schedule B hereto with respect to the ▇▇▇▇▇▇ Selling Shareholders and (ii) Schedule C hereto with respect to the Pioneer Selling Shareholders (collectively, the “Securities”).

At the date hereof, each ▇▇▇▇▇▇ Selling Shareholder delivered to Keystone Operating Partnership, L.P., a Delaware limited partnership (the “Operating Partnership”), in accordance with the Amended and Restated Agreement of Limited Partnership of the Operating Partnership, including the Partnership Unit Designation of Series C Convertible Preferred Units (the “Series C Preferred Units”) and the Partnership Unit Designation of Series D Preferred Units (the “Series D Preferred Units”) which are parts thereof (together with any amendments thereto, the “Operating Partnership Agreement”), an irrevocable Notice of Conversion and other required documentation (each, a “Notice of Conversion” and, collectively, the “Notices of Conversion”) requesting the conversion of an aggregate of 1,664,965 Series C Preferred Units of the Operating Partnership into an aggregate of 2,601,506 Common Shares of the Company. Also on the date hereof, each Pioneer Selling Shareholder holding common units of the Operating Partnership (the “Common Units”) and each Pioneer Selling Shareholder holding Series D Preferred Units delivered to the Operating Partnership, in accordance with the Operating Partnership Agreement, a Notice of Conversion requesting the conversion of an aggregate of 1,076,668 Common Units and 239,555 Series D Preferred Units of the Operating Partnership, respectively, into an aggregate of 1,439,631 Common Shares of the Company. The Company, as general partner of the Operating Partnership, as set forth herein, will issue the Securities as of the date hereof, in satisfaction of the requests contained in such Notices of Conversion (each such conversion, a “Unit Conversion” and collectively, the “Unit Conversions”).

The Company and the Selling Shareholders understand that the Underwriter proposes to make a public offering of the Securities after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) registration statements on Form S-3 (Nos. 333-77627, 333-92741 and 333-110450) covering the registration of the Securities under the Securities Act of 1933, as amended (the “1933 Act”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus supplement in accordance with the provisions of paragraph (b) of Rule 424 (“Rule 424(b)”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Such registration statements, including the exhibits thereto, schedules thereto, if any, and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, at the time they became effective are herein called the “Registration Statement” and the term “Registration Statement” shall be deemed to refer to each registration statement listed above. The final prospectus, including the prospectus supplement relating to the Securities and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, in the form first furnished to the Underwriter for use in connection with the offering of the Securities is herein called the “Prospectus” and the term “Prospectus” shall be deemed to refer to each prospectus forming a part of each registration statement listed above. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or any amendment or supplement to either of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”).

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

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

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company and the Operating Partnership. Each of the Company and the Operating Partnership represents and warrants to the Underwriter as of the date hereof and as of the Closing Time referred to in Section 2(b) hereof, and agrees with the Underwriter, as follows:


	(i) Compliance with Registration Requirements. The Company meets the requirements for use of Form S-3 under the 1933 Act. The Registration Statement has become effective under the 1933 Act and 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 instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with.

At the respective times the Registration Statement and any post-effective amendments thereto (including the filing of the Company’s most recent Annual Report on Form 10-K with the Commission) became effective, at the date of this Agreement and at the Closing Time, the Registration Statement and any amendments and supplements thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 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. Neither the Prospectus nor any amendments or supplements thereto at the time the Prospectus or any such amendment or supplement was issued and at the Closing Time, 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. 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 Company or any Selling Shareholder in writing by the Underwriter expressly for use in the Registration Statement or Prospectus.

Each 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 and the Prospectus delivered to the Underwriter for use in connection with this offering was identical to the electronically transmitted copy thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(ii) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, when they became effective or 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 1933 Act and the 1933 Act Regulations or the 1934 Act and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”), as applicable, and, when read together with the other information in the Prospectus, at the time the Registration Statement became effective, at the time the Prospectus was issued and at the Closing Time, 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, in light of the circumstances under which they were made, not misleading.


	(iii) Independent Accountants. The accountants who certified the financial statements and supporting schedules included in the Registration Statement are independent public accountants as required by the 1933 Act and the 1933 Act Regulations.

(iv) Financial Statements. The financial statements included in the Registration Statement and the Prospectus, together with the related schedules and notes, present fairly the financial position of the Company and its consolidated subsidiaries at the dates indicated and the statement of operations, shareholders’ equity and cash flows of the Company and its consolidated subsidiaries for the periods specified; said 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 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 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 Prospectus. In addition, any pro forma financial information 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 preparing the pro forma financial information included in the Registration Statement and the Prospectus provide a reasonable basis for presenting the significant effects directly attributable to the transactions or events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro forma columns therein reflect the proper application of those adjustments to the corresponding historical financial statement amounts. All historical financial statements and information and all pro forma financial statements and information relating to the Company or any entity acquired or to be acquired by the Company required by the 1933 Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations are included, or incorporated by reference, in the Registration Statement and Prospectus. The statistical and market-related data included in the Registration Statement and the Prospectus are based on or derived from sources which the Company reasonably and in good faith believes are reliable and accurate, and such data agrees with the sources from which they are derived.

(v) Related-Party Transactions. No relationship, direct or indirect, exists between or among any of the Company or any affiliate of the Company, on the one hand, and any trustee, officer, shareholder, customer or supplier of the Company or any affiliate of the Company, on the other hand, which is required by the 1933 Act, the 1934 Act, the 1933 Act Regulations or the 1934 Act Regulations to be described in the Registration Statement or the Prospectus which is not so described or is not described as required. There are no outstanding loans, advances (except normal advances for business expenses in the ordinary course of business) or guarantees of indebtedness by the Company to or for the benefit of any of the officers or trustees of the Company or any of their respective family members, except as disclosed in the Registration Statement and the Prospectus.

(vi) Internal Controls. The Company and its Subsidiaries maintain a system of internal accounting and other controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance


	with management’s general or specific authorization, and (iv) the recorded accounting for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(ix) Good Standing of the Operating Partnership. The Operating Partnership is duly organized and validly existing as a limited partnership in good standing under the laws of the State of Delaware, with partnership power and authority to own, lease and operate its properties, to conduct the business in which it is engaged and proposes to engage as described in the Prospectus and to enter into and perform its obligations under this Agreement. The Operating Partnership is duly qualified or registered as a foreign partnership and is in good standing in each jurisdiction in which such qualification or


	registration 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 register would not result in a Material Adverse Effect.

(x) Good Standing of Subsidiaries. The Operating Partnership is the only Subsidiary that is a “significant subsidiary” of the Company (as such term is defined in Rule 1-02 of Regulation S-X). The only Subsidiaries of the Company are (a) the Subsidiaries listed on Exhibit 21 to the Registration Statement (except for non-material Subsidiaries which have been dissolved or merged into new entities) and (b) certain other Subsidiaries which, considered in the aggregate as a single Subsidiary, do not constitute a “significant subsidiary” as defined in Rule 1-02 of Regulation S-X.

To the knowledge of the Company, each of the Joint Ventures possesses such certificates, authorizations or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct the business now being conducted by it, as described or incorporated by reference in the Prospectus, and none of the Joint Ventures has received notice of any proceedings relating to the revocation or modification of any such certificate, authority or permit which singly or in the aggregate, if the subject of an unfavorable ruling or decision, would have a Material Adverse Effect.

(xii) Capitalization. As of the date of this Agreement, the authorized capital stock of the Company consists of 59,775,035 Common Shares and 5,224,965 preferred shares, par value $.001 per share, of which 30,466,156 Common Shares, 2,760,000 shares of Series D Convertible Redeemable Preferred Shares, 500,000 shares of Series C Convertible Preferred Shares, no shares of Series A Convertible Preferred Shares and no shares of Series B Convertible Preferred Shares are issued and outstanding on the date hereof.

The partnership interest records of the Operating Partnership reflect that (i) the ▇▇▇▇▇▇ Selling Shareholders are the owners of record of the Series C Preferred Units reflected on Schedule B hereto and that 1,573,017 Series C Preferred Units have been pledged by ▇▇▇▇▇▇ Selling Shareholders ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇, the ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ Family Limited Partnership and the ▇▇▇▇▇▇ ▇▇▇▇▇▇ Family Limited Partnership as collateral securities to ▇▇▇▇▇ Fargo Bank (“▇▇▇▇▇ Fargo”) and (ii) the Pioneer Selling Shareholders are the owners of record of the Common Units and the Series D Preferred Units, respectively, reflected on Schedule C hereto and that 527,808 Common Units have been pledged by Pioneer Selling Shareholders ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ Family Trust Number 1, ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ Family Trust Number 2, ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ Family Trust Number 3 and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ Family Trust Number 4 as collateral securities to HSBC Bank USA (“HSBC”).

(xiv) Authorization and Description of Securities. The Securities to be purchased by the Underwriter from the Selling Shareholders have been duly authorized for issuance to the Selling Shareholders upon the Unit Conversions pursuant to the Operating Partnership Agreement and this Agreement and, when issued and delivered to the Selling Shareholders by the Company pursuant to the Operating Partnership Agreement and this Agreement, will be validly issued, fully paid and non-assessable. The Common Shares conform to all statements relating thereto contained in the Prospectus and such description conforms to the rights set forth in the instruments defining the same; any security certificates evidencing the Securities will be in substantially the form incorporated by reference as an exhibit to the Registration Statement and the form of stock certificate evidencing the Securities will comply with all applicable legal requirements, with all applicable requirements of the Company’s declaration of trust and by-laws and with the requirements of the New York Stock Exchange, Inc. (the “NYSE”). No holder of the Securities will be subject to personal liability by reason of being such a holder; the issuance of the Securities is not subject to the preemptive or other similar rights of any securityholder of the Company.


	(xv) Authorization of Agreement. This Agreement and the transactions contemplated herein have been duly authorized by the Company and the Operating Partnership and this Agreement has been duly executed and delivered by the Company and the Operating Partnership.

(xvi) Absence of Defaults and Conflicts. None of the Company, the Operating Partnership or any Subsidiary is in violation of its declaration of trust, partnership agreement, charter, by-laws or other governing instrument (“Governing Instruments”) 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 the Company, the Operating Partnership or any Subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company, the Operating Partnership or any Subsidiary is subject (collectively, “Agreements and Instruments”)

except for such violations or defaults of any Agreements or Instruments that would not result in a Material Adverse Effect; and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein and in the Prospectus (including the issuance of the Securities by the Company to the Selling Shareholders upon the Unit Conversions) and compliance by the Company and the Operating Partnership with their respective obligations hereunder have been duly authorized by all necessary requisite 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 (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company, the Operating Partnership or any Subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that would not result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the Governing Instruments of the Company, the Operating Partnership or any Subsidiary 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 the Company, the Operating Partnership or any Subsidiary or any of their assets, properties or operations, except for such violations that would not have a Material Adverse Effect. As used herein, a “Repayment Event” means any event or 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 material portion of such indebtedness by the Company, the Operating Partnership or any Subsidiary.

(xvii) Absence of Labor Dispute. No labor dispute with the employees of the Company, the Operating Partnership or any Subsidiary exists or, to the knowledge of the Company or the Operating Partnership, is imminent, and the Company and the Operating Partnership are not aware of any existing or imminent labor disturbance by the employees of any of its or any Subsidiary’s principal suppliers, manufacturers, customers or contractors, which, in either case, may reasonably be expected to result in a Material Adverse Effect.

(xviii) 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 Company or the Operating Partnership, threatened, against or affecting the Company, the Operating Partnership or any Subsidiary, which is required to be disclosed in the Registration Statement (other than as disclosed therein), or which might reasonably be expected to result in a Material Adverse Effect or materially adversely affect the consummation of the transactions contemplated in this Agreement or the performance by the Company or the Operating Partnership of their respective obligations hereunder. The aggregate of all pending legal or governmental proceedings to which the Company, the Operating Partnership or any Subsidiary is a party or of which any of their respective properties or assets is the subject which are not described in the Registration Statement, including ordinary routine litigation, could not reasonably be expected to result in a Material Adverse Effect.


	(xix) 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.

(xx) REIT Qualification. Commencing with its taxable year ended December 31, 1993, the Company has been, and upon the sale of the Securities, the Company will continue to be organized and operated in conformity with the requirements for qualification and taxation as a real estate investment trust (a “REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), and the Company’s proposed method of operation as described in the Prospectus will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code, and no actions have been taken (or not taken which are required to be taken) which would cause such qualification to be lost.


	(xxi) Investment Company Act.

(f) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriter, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Underwriter may designate and to maintain such qualifications in effect for a period of not less than one year from the effective date of the Registration Statement; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the effective date of the Registration Statement.

(j) Listing. The Company will use its best efforts to effect the listing of the Securities on the NYSE.

(k) No Manipulation of Market for Securities. Except for the authorization of actions permitted to be taken by the Underwriter as contemplated herein or in the Prospectus, neither the Company nor the Operating Partnership will (a) take, directly or indirectly, any action designed to cause or to result in, or that might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities, and (b) until the Closing Time (i) sell, bid for or purchase the Securities or pay any person any compensation for soliciting purchases of the Securities or (ii) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the Company.

(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 included in 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 of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Underwriter), 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 (i) or (ii) above;

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 by the Underwriter or the Selling Shareholders expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of the Underwriter by Selling Shareholders. Each Selling Shareholder agrees, severally and not jointly, to indemnify and hold harmless the Underwriter and each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any director, officer, employee or affiliate thereof as follows:

provided, however, that this indemnity agreement shall only 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 relating to such Selling Shareholder furnished to the Company by such Selling Shareholder expressly for use in the Registration Statement (or any amendment thereto), or the Prospectus (or any amendment or supplement thereto).

(c) Indemnification of Company, Operating Partnership, Trustees, Officers and the Selling Shareholders. The Underwriter agrees to indemnify and hold harmless the Company and the Operating Partnership, each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any officer, trustee, director, employee or affiliate thereof, and each Selling Shareholder and each person, if any, who controls

any Selling Shareholder 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) or (b) 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 the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto).

(d) 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 6(a) or 6(b) above, counsel to the indemnified parties shall be selected by the Underwriter, and, in the case of parties indemnified pursuant to Section 6(c) above, counsel to the indemnified parties shall be selected by the Company. 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 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless (x) 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 and (y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

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, the Operating Partnership and the Selling Shareholders on the one hand and the Underwriter on the other hand from the offering of the Securities pursuant to this 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, the Operating Partnership and the Selling Shareholders on the one hand and of the Underwriter 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, the Operating Partnership and the Selling Shareholders on the one hand and the Underwriter on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Selling Shareholders and the total underwriting discount received by the Underwriter, in each case as set forth on the cover of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company, the Operating Partnership and the Selling Shareholders on the one hand and the Underwriter 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 omission or alleged omission to state a material fact relates to information supplied by the Company, the Operating Partnership or the Selling Shareholders or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Operating Partnership, the Selling Shareholders and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation 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, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of any 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 ▇▇▇▇ ▇▇▇) 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 the 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 the Underwriter, and each trustee of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or any Selling Shareholder 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 such Selling Shareholder, subject in each case to the preceding two paragraphs. For purposes of this

Section 7, the Company and the Operating Partnership shall be deemed one party, jointly and severally liable for any obligations hereunder.

Anything in this Section 7 to the contrary notwithstanding, no Selling Shareholder will have any obligation under this Section 7 to contribute to the aggregate amount of any losses, liabilities, claims, damages and expenses incurred by an indemnified party unless such Selling Shareholder would be obligated under Section 6(b) to provide indemnification with respect to such losses, liabilities, claims, damages and expenses.

SECTION 8. 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 the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or controlling person, or by or on behalf of the Company, the Operating Partnership or any Selling Shareholder, and shall survive delivery of the Securities to the Underwriter.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Underwriter may terminate this Agreement, by notice to the Company and the Selling Shareholders, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this 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 Company, the Operating Partnership and any of the Subsidiaries considered as one enterprise, 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 the international financial markets, any outbreak of hostilities or escalation thereof, any acts of terrorism involving the United States or other calamity or crisis or any change or development 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 the Underwriter, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the NYSE 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 any of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (v) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8 and 13 shall survive such termination and remain in full force and effect.

(b) Failure By the Company to Effect Unit Conversions.
