In addition, the Indenture has been duly qualified under the 1939 Act.

At the respective times the Registration Statement (including any Rule 462(b) Registration Statement) and any post-effective amendments thereto (including the filing of the Company's most recent Annual Report on Form 10-K for the year ended December 31, 2002 with the Commission (the "Annual Report")) became effective and as of the date hereof, the Registration Statement (including any Rule 462(b) Registration Statement) and any amendments thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act and the rules and regulations of the Commission under the 1939 Act (the "1939 Act Regulations") and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. At the date of the Prospectus and at the Closing Time as defined below, neither the Prospectus nor any amendments and supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Each preliminary prospectus and prospectus filed as part of the Registration Statement as originally filed or as part of any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so filed in all material respects with the 1933 Act Regulations and the Prospectus delivered to the Underwriter for use in connection with the offering of the Notes will,

at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(2) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission thereunder (the "1934 Act Regulations") and, when read together with the other information in the Prospectus, at the date of the Prospectus and at the Closing Time did not and will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) The Company will deliver to the Underwriter a conformed copy of the Registration Statement as originally filed and of each amendment thereto filed prior to the termination of the initial offering of the Notes (including exhibits filed therewith or incorporated by reference therein and the documents incorporated by reference into the Prospectus pursuant to Item 12 of Form S-3).

(f) Until the termination of the initial offering of the Notes, if any event shall occur as a result of which it is necessary, in the opinion of counsel for the Underwriter, to amend or supplement the Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered, the Company will promptly notify the Underwriter and either (i) forthwith prepare and furnish to the Underwriter an amendment of or supplement to the Prospectus or (ii) make an appropriate filing pursuant to Section 13, 14 or 15 of the 1934 Act, in each case, in form and substance reasonably satisfactory to counsel for the Underwriter, which will amend or supplement the Prospectus so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered, not misleading.

"Earning statement", "make generally available" and "effective date" will have the meanings contained in Rule 158 of the 1933 Act Regulations.

(i) The Company will use the net proceeds received by it from the sale of the Notes in the manner specified in the Prospectus under the caption "Use of Proceeds" in all material respects.

(j) The Company currently intends to continue to qualify as a "real estate investment trust" under the Code, and use its best efforts to continue to meet the requirements to qualify as a "real estate investment trust" under the Code.

(k) The Company will timely file any document which it is required to file pursuant to the 1934 Act prior to the termination of the offering of the Notes.

(l) The Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the 1933 Act relating to debt securities issued or guaranteed by the Company and having a maturity of more than one year from the date of issue, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the Underwriter for a period beginning at the date of this Underwriting Agreement and ending at the later of the Closing Time or the lifting of trading restrictions by the Underwriter; provided however, such period shall not end later than the 15^th day after the Closing Time.

In giving such opinion, such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York and the federal law of the United States, upon the opinions of counsel satisfactory to the Underwriter and may rely on an opinion dated the Closing time of ▇▇▇▇▇▇▇ LLP as to matters governed by the laws of the State of Maryland and on an opinion of ▇▇▇▇▇▇▇▇ & Worcester LLP as to matters governed by the laws of the Commonwealth of Massachusetts.

SECTION 6. Indemnification.

(a) Indemnification of Underwriter. The Company agrees to indemnify and hold harmless the Underwriter, its officers and directors 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 as follows:

(i): against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;
(ii): against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) 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 expressly for use in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); and provided, further, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of the Underwriter, its officers or directors, or the benefit of any person controlling the Underwriter, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto sufficiently in advance of the required delivery time to enable the Underwriter to make delivery and excluding documents incorporated or deemed to be incorporated by reference therein) was not sent or given by or on behalf of the Underwriter to such person asserting any such losses, claims, damages or liabilities at or prior to the written confirmation of the sale of such Notes

to such person, if required by law so to have been delivered, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or expense.

(b) Indemnification of Company, Trustees and Officers. The Underwriter agrees to indemnify and hold harmless the Company, its trustees, each of its officers who signed the Registration Statement, and 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 against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. The indemnifying party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified parties and payment of all fees and expenses. The indemnified parties shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified parties unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense and employ counsel or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified parties and the indemnifying party and the indemnified parties shall have been advised by such counsel that there may be one or more legal defenses available to them which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified parties, it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for the indemnified parties, which firm shall be designated in writing by the indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred). No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to

such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriter, on the other hand, from the offering of the Notes pursuant hereto 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, on the one hand, and 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, on the one hand, and the Underwriter, on the other hand, in connection with the offering of the Notes pursuant hereto shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Notes (before deducting expenses) received by the Company 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 such Notes as set forth on such cover.

The relative fault of the Company, 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 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 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 Notes 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 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.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Underwriting Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto or thereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of and payment for the Notes.

SECTION 9. Termination.

(a) The Underwriter may terminate this Underwriting Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has occurred any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as one enterprise which, in the judgment of the Underwriter, is material and adverse and makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Notes; (ii) any downgrading in the rating of any debt securities of the Company by any NRSRO, or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating); provided, however the Underwriter acknowledges that on July 8, 2003 ▇▇▇▇▇'▇ changed the Company's rating outlook to "negative" and on July 22, 2003 S&P changed the Company's rating outlook to "negative" and neither ▇▇▇▇▇'▇ July 8, 2003 action or S&P's July 22, 2003 action shall give rise to a termination right under this Section 9; (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of the Underwriter, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Notes, whether in the primary market or in respect of dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of securities or clearance services in the United States or (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Underwriter, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Notes.

(b) If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4, and provided further that Sections 6 and 7 hereof shall survive such termination.

SECTION 10. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriter shall be directed to it at ▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇., ▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ or via fax at (▇▇▇) ▇▇▇-▇▇▇▇, attention Fixed Income Syndicate; and notices to the Company shall be directed to it at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, attention of ▇▇▇▇ ▇. ▇▇▇▇▇▇.

SECTION 11. Parties. This Underwriting Agreement shall inure to the benefit of and be binding upon the Company, and the Underwriter and its respective successors.

provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective successors, and said controlling persons and officers and trustees and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.
