(cc) Each of the Company, the Subsidiaries and the Joint Venture Entities owns or possesses adequate rights to use all material patents, patent applications, trademarks, service marks, trade names, trademark registrations, service mark registrations, copyrights and licenses necessary for the conduct of its business and has no reason to believe that the conduct of its business will conflict with, and has not received any notice of any claim of conflict with, any such rights of others.

Company, the Operating Partnership or any Subsidiary is a party are accurate in all material respects. To the best knowledge of such counsel, there are no contracts or other documents which are required to be described in the Prospectus or filed as exhibits to the Registration Statement by the Securities Act or by the Securities Act Regulations which have not been described in the Prospectus or filed as exhibits to the Registration Statement or incorporated therein by reference as permitted by the Securities Act Regulations. (xiii) To the best knowledge of such counsel, no relationship, direct or indirect, exists between or among any of the Transaction Entities on the one hand, and the directors, officers, stockholders, customers or suppliers of the Transaction Entities on the other hand, which is required to be described in the Prospectus which is not so described. (xiv) To the best knowledge of such counsel and other than as described in the Prospectus, no Transaction Entity (i) is in violation of its charter, by-laws, certificate of limited partnership, agreement of limited partnership or other similar organizational document, (ii) is in default, and no event has occurred which, with notice or lapse of time or both, would constitute a default, in the due performance or observance of any term, covenant or condition contained in any material indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which it is a party or by which it is bound or to which any of the Properties or any of its other properties or assets is subject and which has been filed as an exhibit to the Registration Statement or (iii) is in violation of any law, ordinance, governmental rule, regulation or court decree to which it or the Properties or any of its other properties or assets may be subject or has failed to obtain any material license, permit, certificate, franchise or other governmental authorization or permit necessary to the ownership of the Properties or any of its other properties or assets or to the conduct of its business, except, in the case of each of (i), (ii) and (iii) immediately above, any such violation or default that would not have a Material Adverse Effect. (xv) Commencing with its taxable year ended December 31, 1997, the Company was organized and has been operated in conformity with the requirements for qualification and taxation as a REIT under the Code and the proposed method of operation of the Company will enable the Company to continue to meet the requirements for qualification and taxation as a REIT under the Code and the Operating Partnership is classified as a partnership and not as (a) an association taxable as a corporation or (b) a "publicly traded partnership" taxable as a corporation under Section 7704(a) of the Code. (xvi) Neither the Company nor the Operating Partnership is an "investment company" within the meaning of such term under the Investment Company Act of 1940, as amended and the rules and regulations of the Commission thereunder. (xvii) The Shares have been approved for listing on the NYSE, subject to official notice of issuance. (xviii) The Registration Statement was declared effective under the Securities Act as of the date and time specified in such opinion, the 23

Prospectus was filed with the Commission pursuant to the subparagraph of Rule 424(b) of the Securities Act Regulations specified in such opinion on the date specified therein and, to the best knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and, to the best knowledge of such counsel, no proceeding for that purpose is pending or threatened by the Commission. (xix) The Registration Statement, at the time that it became effective, and the Prospectus, as of its date and as of the date hereof (in each case, other than documents incorporated by reference therein and the financial statements, supporting schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which no opinion is rendered), complied as to form, in all material respects, with the applicable requirements of the Securities Act and the Securities Act Regulations. (xx) The documents incorporated by reference in the Prospectus (other than the financial statements, supporting schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which no opinion is rendered), when they became effective or were filed with the Commission, as the case may be, complied as to form, in all material respects, with the requirements of the Securities Act, the Securities Act Regulations, the Exchange Act, and the Exchange Act Regulations, as applicable. (xxi) The statements contained in the Prospectus under the captions "Description of Common Stock," "Restrictions on Ownership of Capital Stock," and "Material Federal Income Tax Consequences," insofar as those statements are descriptions of contracts, agreements or other legal documents, or they describe federal statutes, rules and regulations or legal conclusions, constitute a fair summary thereof, and the opinion of such counsel filed as Exhibit 8 to the Registration Statement is confirmed and the Underwriter may rely upon such opinion as if it were addressed to it. In rendering such opinion, such counsel may (i) state that its opinion is limited to matters governed by the Federal laws of the United States of America and the States of Delaware, Maryland and New York; (ii) rely (to the extent such counsel deems proper and specifies in their opinion), as to matters involving the application of the laws of the States of Maryland and Delaware, upon the opinion of other counsel of good standing, PROVIDED that such other counsel is reasonably satisfactory to counsel for the Underwriter and furnishes a copy of its opinion to the Underwriter; (iii) in respect of matters of fact, upon certificates of officers of the Company or its Subsidiaries, PROVIDED that such counsel shall state that it believes that both the Underwriter and it are justified in relying upon such opinions of local counsel. Such counsel shall also have furnished to the Underwriter a written statement, addressed to the Underwriter and dated such Delivery Date, in form and substance satisfactory to the Underwriter and counsel to the Underwriter, to the effect that (x) such counsel has acted as counsel to the Company in connection with the preparation of the Registration Statement and the Prospectus, and (y) based on the foregoing, no facts have come to the attention of such counsel which lead it to believe that the Registration Statement, as of the Effective Date and as of the date the Company's Annual Report on Form 10-K was filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to 24

make the statements therein not misleading, or that the Prospectus as of its date or at the Delivery Date, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The foregoing opinion and statement may be qualified by a statement to the effect that such counsel does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus and may state that such counsel makes no statement with respect to the financial statements and notes thereto and other financial data included in the Registration Statement or the Prospectus. (e) The Underwriter shall have received from Clifford Chance Rogers & Wells LLP, counsel for the Underwriter, such opinion or opinions, dated such Delivery Date, with respect to the issuance and sale of the Shares, the Registration Statement, the Prospectus and other related matters as the Underwriter may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. (f) At the time of execution of this Agreement, the Underwriter shall have received from Ernst & Young LLP a letter, in form and substance satisfactory to the Underwriter, addressed to the Underwriter and dated the date hereof (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, and (ii) stating, as of the date hereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Prospectus, as of a date not more than five days prior to the date hereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants' "comfort letters" to underwriters in connection with registered public offerings as contemplated in the Statement on Auditing Standards No. 72. (g) With respect to the letter of Ernst & Young LLP referred to in the preceding paragraph and delivered to the Underwriter concurrently with the execution of this Agreement (the "INITIAL LETTER"), the Company shall have furnished to the Underwriter a letter (the "BRING-DOWN LETTER") of such accountants, addressed to the Underwriter and dated such Delivery Date (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date of the bring-down letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Prospectus, as of a date not more than five days prior to the date of the bring-down letter), the conclusions and findings of such firm with respect to the financial information and other matters covered by the initial letter and (iii) confirming in all material respects the conclusions and findings set forth in the initial letter. (h) The Company and the Operating Partnership shall have furnished to the Underwriter a certificate, dated such Delivery Date, of its, or its general partner's Chairman of the Board, its President or a Vice President and its chief financial officer stating that: 25

(i) The representations, warranties and agreements of the Transaction Entities in Section 1 are true and correct as of such Delivery Date; the Company has complied with all its agreements contained herein; and the conditions set forth in Sections 7(a) and (b) have been fulfilled; and (ii) They have carefully examined the Registration Statement and the Prospectus and, in their opinion (A) as of the Effective Date, the Registration Statement and Prospectus did not include any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary to make the statements therein (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading, and (B) since the Effective Date no event has occurred which should have been set forth in a supplement or amendment to the Registration Statement or the Prospectus. (i) The NYSE shall have approved the Shares for listing, subject only to official notice of issuance. (j) On the Delivery Date, counsel for the Underwriter shall have been furnished with such documents and opinions as they may require for the purpose of enabling them to pass upon the issuance and sale of the Shares as herein contemplated and related proceedings, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Transaction Entities in connection with the issuance and sale of the Shares as herein contemplated shall be satisfactory in form and substance to the Underwriter and counsel for the Underwriter. (k) The Company shall have furnished or caused to be furnished to you such further certificates and documents as the Underwriter or counsel to the Underwriter shall have reasonably requested. (l) Intentionally omitted. All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriter. Any certificate or document signed by any officer of the Transaction Entities and delivered to the Underwriter, or to counsel for the Underwriter, shall be deemed a representation and warranty by the Transaction Entities to the Underwriter as to the statements made therein. 8. EFFECTIVE DATE OF AGREEMENT. This Agreement shall become effective: (i) upon the execution hereof by the parties hereto; or (ii) if, at the time this Agreement is executed and delivered, it is necessary for a post-effective amendment to the Registration Statement to be declared effective before the offering of the Shares may commence, when notification of the effectiveness of such post-effective amendment has been released by the Commission. 9. Intentionally omitted. 10. INDEMNIFICATION AND CONTRIBUTION. 26

(a) The Transaction Entities jointly and severally, shall indemnify and hold harmless the Underwriter, its officers and employees and each person, if any, who controls the Underwriter within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Shares), to which that Underwriter, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus Supplement, the Registration Statement or the Prospectus or in any amendment or supplement thereto or (ii) the omission or alleged omission to state in any Preliminary Prospectus Supplement, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading, and shall reimburse the Underwriter and each such officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; PROVIDED, HOWEVER, that the Transaction Entities shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus Supplement, the Registration Statement or the Prospectus, or in any such amendment or supplement, in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 10(e). The foregoing indemnity agreement is in addition to any liability which the Transaction Entities may otherwise have to the Underwriter or to any officer, employee or controlling person of the Underwriter. (b) The Underwriter shall indemnify and hold harmless each Transaction Entity, its officers and employees, each of its directors, and each person, if any, who controls each Transaction Entity within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which each Transaction Entity or any such director, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus Supplement, the Registration Statement or the Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus Supplement, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for inclusion therein, and shall reimburse each Transaction Entity and any such director, officer or controlling person for any legal or other expenses reasonably 27

incurred by each Transaction Entity or any such director, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which the Underwriter may otherwise have to each Transaction Entity or any such director, officer, employee or controlling person. (c) Promptly after receipt by an indemnified party under this Section 10 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced by such failure and, PROVIDED FURTHER, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 10. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 10 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. (d) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 10(a) or 10(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Transaction Entities on the one hand and the Underwriter on the other from the offering of the Shares or (ii) if the allocation provided by clause (i) above 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 28

Transaction Entities on the one hand and the Underwriter on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Transaction Entities on the one hand and the Underwriter on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares purchased under this Agreement (before deducting expenses) received by the Transaction Entities, on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the Shares purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Shares under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the 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 Transaction Entities or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Transaction Entities and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section shall be deemed to include, for purposes of this Section 10(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which the Underwriter has otherwise paid or become liable to pay by reason of any 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. (e) The Underwriter confirms and each Transaction Entity acknowledges that (i) the statements with respect to the public offering of the Shares by the Underwriter set forth on the cover page of the Prospectus Supplement and (ii) the name of the Underwriter and the number of Shares which it is purchasing and the information contained in the third, tenth and eleventh paragraphs, in each case appearing under the caption "Underwriting" in the Prospectus Supplement are correct and constitute the only information concerning the Underwriter furnished in writing to the Company by or on behalf of the Underwriter specifically for inclusion in the Registration Statement and the Prospectus. 11. TERMINATION. The obligations of the Underwriter hereunder may be terminated by notice given to and received by the Company prior to delivery of and payment for the Shares if, prior to that time, any of the following events shall have occurred or if the Underwriter shall decline to purchase the Shares for any reason permitted under this Agreement: (a) (i) Any of the Transaction Entities or any Property shall have sustained, since the date of the latest financial statements included in the Prospectus, any loss or interference with its business from fire, explosion, flood or other calamity, 29

whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus or (ii) since the date of the latest financial statements included in the Prospectus there shall have been any change in the capital stock or long-term debt of any Transaction Entity or any change, or any development involving a prospective change, in or affecting any Property or the general affairs, management, financial position, stockholders' equity or results of operations of any Transaction Entity, otherwise than as set forth or contemplated in the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Underwriter, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus; (b) Subsequent to the execution and delivery of this Agreement there shall have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange or the American Stock Exchange or in the over-the-counter market, or trading in any securities of the Company on any exchange or in the over-the-counter market, shall have been suspended or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by Federal or New York state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (iv) there shall have occurred such a material adverse change in general economic, political or financial conditions (or the effect of international conditions on the financial markets in the United States shall be such) as to make it, in the sole judgment of the Underwriter, impracticable or inadvisable to proceed with the public offering or delivery of the Shares being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus; or (c) The Transaction Entities shall have failed at or prior to such Delivery Date to have performed or complied with any of their agreements herein contained and required to be performed or complied with by them hereunder at or prior to such Delivery Date. 12. REIMBURSEMENT OF UNDERWRITER'S EXPENSES. If (a) the Company shall fail to tender the Shares for delivery to the Underwriter by reason of any failure, refusal or inability on the part of the Transaction Entities to perform any agreement on their part to be performed, or because any condition specified in Sections 11(a) and (c) hereof required to be fulfilled by the Transaction Entities is not fulfilled, the Transaction Entities will reimburse the Underwriter for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Underwriter in connection with this Agreement and the proposed purchase of the Shares, and upon demand the Transaction Entities shall pay the full amount thereof to the Underwriter. If this Agreement is terminated pursuant to Section 11(b) by reason of the default of the Underwriter, the Transaction Entities shall not be obligated to reimburse the defaulting Underwriter on account of those expenses. 13. NOTICES, ETC. All statements, requests, notices and agreements hereunder shall be in writing, and: 30

(a) if to the Underwriter, shall be delivered or sent by mail, telex or facsimile transmission to Salomon Smith Barney Inc., 388 Greenwich Street, 32nd Floor, New York, New York 10013, Attention: Jeff Horowitz.

This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (a) the representations, warranties, indemnities and agreements of the Transaction Entities contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control the Underwriter within the meaning of Section 15 of the Securities Act and (b) the indemnity agreement of the Underwriter contained in Section 10(b) of this Agreement shall be deemed to be for the benefit of directors of the Transaction Entities, officers of the Company who have signed the Registration Statement and any person controlling the Transaction Entities within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 14, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. 15. SURVIVAL. The respective indemnities, representations, warranties and agreements of the Transaction Entities and the Underwriter contained in this Agreement or made by or on behalf on them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Shares and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them. 16. DEFINITION OF THE TERMS "BUSINESS DAY" AND "SUBSIDIARY". For purposes of this Agreement, (a) "business day" means any day on which the New York Stock Exchange, Inc. is open for trading and (b) "subsidiary" has the meaning set forth in Rule 405 of the Securities Act Regulations. 17.
