     (kk) The assets of the Company and its subsidiaries do not constitute “plan assets” of an ERISA regulated employee benefit plan.

     (ll) The Company and its subsidiaries (including any predecessor entities) have filed all foreign, federal, state and local tax returns that are required to be filed or have requested extensions thereof (except in any case in which the failure so to file could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect) and have paid all taxes required to be paid by them and any other assessment, fine or penalty levied against them, to the extent that any of the foregoing is due and payable, except for any such assessment, fine or penalty that (i) is currently being contested in good faith, (ii) could not individually or in the aggregate reasonably be expected to have a Material Adverse Effect or (iii) is described in, or contemplated by, the Prospectus. No tax deficiency has been determined adversely to the Company which has had (nor does the Company have any knowledge of any tax deficiency which, if determined adversely to it might have) a Material Adverse Effect.

     (mm) Except as disclosed in the Prospectus, to the knowledge of the Company, there is no pending or threatened special assessment, tax reduction proceeding or other action which could increase or decrease the real property taxes or assessments of any Property or properties, which, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

     (nn) The REIT has been organized and, commencing with its taxable year ended December 31, 2004, has operated in conformity with the requirements for qualification and taxation as a real estate investment trust under the Code and currently intends to operate in a manner which allows the Company to continue to meet the requirements for qualification and taxation as a REIT under the Code.

     (oo) The description of the REIT’s organization and current and proposed method of operation set forth in the Prospectus under the heading “Material United States Federal Income Tax Considerations” is an accurate and fair summary of the matters referred to therein.

     (pp) The Operating Partnership has been properly classified either as a partnership or as an entity disregarded as separate from the REIT for Federal income tax purposes throughout the period from its formation through the date hereof.

     (qq) Since the date as of which information is given in the Prospectus through the date hereof, and except as may otherwise be disclosed in the Prospectus, (i) neither the Company nor any subsidiary thereof has (a) issued or granted any securities, (b) incurred any liability or obligation, direct or contingent, other than liabilities and obligations which were incurred in the ordinary course of business, (c) entered into any transaction not in the ordinary course of business or (d) declared or paid any dividend on its capital stock; and (ii) there has been no Material Adverse Effect.

     (rr) Neither the Company nor any subsidiary thereof (i) is in violation of its charter, certificate of incorporation, declaration of trust, 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 performance or observance of any obligation, agreement, term, covenant or condition contained in a contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease (under which the Company or subsidiary is landlord or otherwise), ground lease or air space lease (under which the Company or subsidiary is tenant), development agreement, reciprocal easement agreement, deed restriction, parking management agreements, 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, except for any such default which could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect 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.

     (ss) Neither the Company nor any subsidiary thereof, nor any director, trustee, officer, agent, employee or other person associated with or acting on behalf of the Company or any of its subsidiaries, has used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977; or made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment.

     (tt) Neither the Company nor any subsidiary thereof, 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.

     (uu) Other than this Agreement and as set forth in the Prospectus under the heading “Underwriting,” there are no contracts, agreements or understandings between the Company and any person that would give rise to a valid claim against the Company or any Underwriter for a brokerage commission, finder’s fee or other like payment with respect to the consummation of the transactions contemplated by this Agreement.

     (vv) Except as stated in this Agreement and in the Prospectus, neither the Company nor any of its subsidiaries nor any of their respective officers, directors, trustees, members or controlling persons has taken, or will take, directly or indirectly, any action designed to or that could reasonably be expected to result in a violation of Regulation M under the Exchange Act or cause or result in stabilization or manipulation of the price of the Common Shares to facilitate the sale or resale of the Shares.

     (ww) The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 and 15d-15 under the Exchange Act), which (i) are designed to ensure that material information relating to the Company, including its subsidiaries, is made known to the REIT’s principal executive officer and principal financial officer by others within those entities; (ii) have been evaluated for effectiveness as of June 30, 2005; and (iii) are effective in all material respects to perform the functions for which they were established.

     (xx) The Company and its subsidiaries (i) make and keep books and records that are accurate in all material respects and (ii) maintain internal accounting controls which provide reasonable assurance that (A) transactions are executed in accordance with management’s general and specific authorizations; (B) transactions are recorded as necessary to permit preparation of its financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

     (yy) Except as disclosed in the Registration Statement and Prospectus, (A) the Company is not aware of (i) any significant deficiency or material weakness in the design or operation of internal control over financial reporting which is reasonably likely to adversely affect the ability of the Company to record, process, summarize and report financial information, or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in internal control over financial reporting, and (B) there have been no changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect the Company’s internal control over financial reporting, including any corrective actions with regard to significant deficiencies and material weaknesses.

     (zz) Any statistical and market-related data included in the Registration Statement and the Prospectus are based on or derived from sources that the Company believes to be reliable and

accurate, and the Company has obtained the written consent to the use of such data from such sources to the extent required.

          2. Purchase of the Shares by the Underwriters. On the basis of the representations and warranties contained in, and subject to the terms and conditions of, this Agreement, the REIT agrees to sell 17,100,000 Firm Shares to the several Underwriters and each of the Underwriters, severally and not jointly, agrees to purchase the number of Firm Shares set forth opposite that Underwriter’s name in Schedule 1 hereto. The respective purchase obligations of the Underwriters with respect to the Firm Shares shall be rounded among the Underwriters to avoid fractional shares, as the Representative may determine.

          In addition, the REIT grants to the Underwriters an option to purchase up to 2,565,000 Option Shares. Such option is granted solely for the purpose of covering over-allotments in the sale of Firm Shares and is exercisable as provided in Section 4 hereof. Option Shares shall be purchased severally for the account of the Underwriters in proportion to the number of Firm Shares set forth opposite the name of such Underwriters in Schedule 1 hereto. The respective purchase obligations of each Underwriter with respect to the Option Shares shall be adjusted by the Representative so that no Underwriter shall be obligated to purchase Option Shares other than in 100-share amounts. The price of both the Firm Shares and any Option Shares shall be $19.3325 per share.

          The REIT shall not be obligated to deliver any of the Shares to be delivered on the First Delivery Date or the Second Delivery Date (as hereinafter defined), as the case may be, except upon payment for all of the Shares to be purchased on such Delivery Date as provided herein.

          3. Offering of Shares by the Underwriters. Upon authorization by the Representative of the release of the Firm Shares, the several Underwriters propose to offer the Firm Shares for sale upon the terms and conditions set forth in the Prospectus.

          4. Delivery of and Payment for the Shares. Delivery of and payment for the Firm Shares shall be made at the offices of Sullivan & Cromwell LLP, 125 Broad Street, New York, NY 10004, or at such other date or place as shall be determined by agreement between the Representative and the REIT, at 10:00 A.M., New York City time, on the third full business day following the date of this Agreement or on the fourth full business day if the Agreement is executed after the daily closing time of the NYSE (unless postponed in accordance with the provisions of Section 9 hereof). This date and time are sometimes referred to as the “First Delivery Date.” On the First Delivery Date, the REIT shall deliver or cause to be delivered certificates representing the Firm Shares to the Representative for the account of each Underwriter against payment to, or upon the order of, the REIT of the purchase price by wire transfer of immediately available funds. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. Upon delivery, the Firm Shares shall be registered in such names and in such denominations as the Representative shall request in writing not less than two full business days prior to the First Delivery Date. The REIT shall make the certificates representing the Firm Shares available for inspection by the Representative in New York, New York, not later than 2:00 P.M., New York City time, on the business day prior to the First Delivery Date.

          At any time on or before the thirtieth day after the date of this Agreement, the option granted in Section 2 may be exercised, in whole or in part, from time to time, by prior written notice being given to the REIT by the Representative. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised, the names in which the Option Shares are to be registered, the denominations in which the Option Shares are to be issued and the date and time, as determined by the Representative, when the Option Shares are to be delivered; provided, however, that this date and time shall not be earlier than the First Delivery Date, nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. The date and time the Option Shares are delivered are sometimes referred to as the “Second Delivery Date” and the First Delivery Date and the Second Delivery Date are sometimes each referred to as a “Delivery Date.”

          Delivery of and payment for the Option Shares shall be made at the place specified in the first sentence of the first paragraph of this Section 4 (or at such other place as shall be determined by agreement between the Representative and the REIT) at 10:00 A.M., New York City time, on the Second Delivery Date. On the Second Delivery Date, the REIT shall deliver or cause to be delivered the certificates representing the Option Shares to the Representative for the account of each Underwriter against payment to, or upon the order of, the REIT of the purchase price by wire transfer of immediately available funds. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. Upon delivery, the Option Shares shall be registered in such names and in such denominations as the Representative shall request in the aforesaid written notice. The REIT shall make the certificates representing the Option Shares available for inspection by the Representative in New York, New York, not later than 2:00 P.M., New York City time, on the business day prior to the Second Delivery Date.

          5. Further Agreements of the REIT. The REIT agrees:

     (h) Promptly from time to time to take such action as the Representative may reasonably request to qualify the Shares for offering and sale under the securities, real estate syndication or Blue Sky laws of such jurisdictions as the Representative may request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Shares;

     (i) For a period of 90 days from the date of the Prospectus (the “Lock-Up Period”), not to, directly or indirectly, (i) offer for sale, sell, contract to sell, pledge or otherwise dispose of (or enter into any transaction or device which is designed to, or could reasonably be expected to, result in the disposition by any person at any time in the future of) any Common Shares or securities convertible into or exercisable or exchangeable for or that represent the right to receive any Common Shares (other than (x) the Shares and Common Shares issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans described in the Prospectus and existing on the date hereof and (y) Units that are issued in connection with an acquisition of properties by the Company and that are not redeemable for any Common Shares during the Lock-Up Period), or sell or grant options, rights or warrants with respect to any Common Shares or securities convertible into or exercisable or exchangeable for or that represent the right to receive any Common Shares (other than the grant of options pursuant to option plans described in the Prospectus and existing on the date hereof), or (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Common Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Shares or other securities, in cash or otherwise, (iii) file or cause to be filed a registration statement with respect to any of the Common Shares or securities convertible, exercisable or exchangeable into Common Shares or any other securities of the Company, or (iv) publicly disclose the intention to do any of the foregoing, in each case without the prior written consent of the Representative on behalf of the Underwriters; and to cause each of the persons identified on Schedule 3 hereto, to furnish to the Representative, at or prior to the date hereof, a Lock-Up Agreement, in form and substance satisfactory to counsel for the Underwriters, pursuant to which each such person shall agree not to, directly or indirectly, (i) offer for sale, sell, contract to sell, pledge or otherwise dispose of (or enter into any transaction or device which is designed to, or could reasonably be expected to, result in the disposition by any person at any time in the future of) any Common Shares or securities convertible into, exchangeable for or that represent the right to receive any Common Shares, (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Common Shares, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Shares or other securities, in cash or otherwise, (iii) cause to be filed a registration statement with respect to any of the Common Shares or securities convertible, exercisable or exchangeable into Common Shares or any other securities of the Company, or (iv) publicly disclose the intention to do any of the foregoing, for a period of 90 days from the date of the Prospectus, in each case without the prior written consent of the Representative on behalf of the Underwriters; provided, however, that the foregoing shall not apply to bona fide gifts, sales or other dispositions of shares of any class of the REIT’s capital stock, in each case that are made exclusively between and among such person or members of such person’s family, or affiliates of such person, so long as it shall be a condition to any such transfer that (i) the transferee/donee agrees to be bound by the terms of the Lock-Up Agreement to the same extent as if the transferee/donee were a party hereto, (ii) no filing by any party (donor, donee, transferor or

     (a) If, at the time this Agreement is executed and delivered, it is necessary for the Registration Statement or a post-effective amendment thereto to be declared effective before the offering of the Shares may commence, the Registration Statement or such post-effective amendment shall have become effective not later than 5:30 P.M., New York City time, on the date hereof, or at such later date and time as shall be consented to in writing by the Representative, and all filings, if any, required by Rules 424 and 430A under the Rules and Regulations shall have been timely made; no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceeding for that purpose shall have been instituted or, to the knowledge of the Company, or any Underwriter, threatened by the Commission, and any request of the Commission for additional information (to be included in the Registration Statement or the Prospectus or otherwise) shall have been complied with to the satisfaction of the Representative.

     (b) Subsequent to the effective date of this Agreement, there shall not have occurred (i) any event that would, in the judgment of the Representative, result in or cause a Material Adverse Effect, or (ii) any event or development relating to or involving the Company or any of its subsidiaries, or any partner, officer, director or trustee of the Company or any of its subsidiaries, which makes any statement of a material fact made in the Prospectus untrue or which, in the opinion of the REIT and its counsel or the Underwriters and their counsel, requires the making of any addition to or change in the Prospectus in order to state a material fact required by the Securities Act or any other law to be stated therein or necessary in order to make the statements therein not misleading, if amending or supplementing the Prospectus to reflect such event or development would, in the judgment of the Representative, adversely affect the market for the Shares.

     (c) All corporate proceedings and other legal matters incident to the authorization, form and validity of this Agreement, the Shares, the Registration Statement and the Prospectus, and all other legal matters relating to this Agreement and the transactions contemplated hereby and thereby shall be reasonably satisfactory in all material respects to counsel for the Underwriters, and the REIT shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.

     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, Ohio, New York and/or the law of any other relevant jurisdiction, as applicable; (ii) in respect of matters of fact, upon certificates of officers of the REIT or the Operating Partnership; provided that such counsel shall state that it believes that both the Underwriters and it are justified in relying upon such certificates.

     Such counsel shall also have furnished to the Representative a written statement, addressed to the Underwriters and dated such Delivery Date, in form and substance satisfactory to the Representative and counsel to the Underwriters, 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 has participated in discussions with representatives of the Company and its independent registered public accounting firm, 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, 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 make the statements therein not misleading, or that the Prospectus as of its date and at the Delivery Date contains any untrue statement of a material fact 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 be further qualified by a statement to the effect that such counsel expresses no belief with respect to the financial statements and notes thereto and other financial and statistical data included in the Registration Statement or the Prospectus.

     (g) With respect to the letter of Deloitte & Touche LLP referred to in the preceding paragraph and delivered to the Representative concurrently with the execution of this Agreement (the “initial letter”), the Company shall have furnished to the Representative a letter (the “bring-down letter”) of such accountants, addressed to the Underwriters and dated such Delivery Date (i) confirming that they are an independent registered public accounting firm 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 three 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 shall have furnished to the Representative a certificate, dated such Delivery Date, of its principal executive officer and principal financial officer, stating that:

     (i) The representations, warranties and agreements of the Company 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;

     (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 not misleading (with respect to the Prospectus, in light of the circumstances under which they were made), 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; and

     (iii) No stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are contemplated by the Commission; and

     (i) Neither the Company nor any subsidiary thereof shall have sustained since the date of the latest audited financial statements included in the Prospectus (A) any loss or interference with its business from fire, explosion, flood or other calamity, 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 (B) since such date, there shall not have been any change in the capital stock or long-term debt of the Company or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, shareholders’ equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Prospectus, the effect of which, in any such case described in clause (A) or (B), is, in the judgment of the Representative, 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.

     (j) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the NYSE or the American Stock Exchange or in the over-the-counter market, or trading in any securities of the REIT on the NYSE, shall have been suspended or materially limited, or the settlement of such trading generally shall have been materially disrupted 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 any state authority, (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, including, without limitation, as a result of terrorist activities after the date hereof, or the effect of international conditions on the financial markets in the United States shall be such as to make it, in the judgment of the Representative, 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.

     (k) The NYSE shall have approved the Shares for listing, subject only to official notice of issuance.

     (l) The NASD shall have confirmed that it has not raised any objection with respect to the fairness and reasonableness of the underwriting terms and arrangements.

     (m) On each Delivery Date, counsel for the Underwriters 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 Company in connection with the issuance and sale of the Shares as herein contemplated shall be reasonably satisfactory in form and substance to the Representative and counsel for the Underwriters.

     (n) You shall have been furnished, at or prior to the date hereof, with the Lock-Up Agreements.

     (o) The REIT shall have furnished or caused to be furnished to you such further certificates and documents as the Representative or counsel to the Underwriters shall have reasonably requested.

     (p) In the event that the Underwriters exercise their option provided in Section 2 hereof to purchase all or any portion of the Option Shares, the representations and warranties of the Company contained herein and the statements in any certificates furnished by the Company hereunder shall be true and correct as of each Date of Delivery and, at the relevant Date of Delivery, the Representative shall have received:

     (i) A certificate, dated such Date of Delivery, of the Company’s principal executive officer and principal financial officer, confirming that the certificate delivered on the First Delivery Date pursuant to Section 7(h) hereof remains true and correct as of such Date of Delivery.

     (ii) The favorable opinion of Hogan & Hartson L.L.P., counsel for the Company, in form and substance satisfactory to counsel for the Underwriters, dated such Date of Delivery, relating to the Option Shares to be purchased on such Date of Delivery and otherwise to the same effect as the opinions required by Section 7(d) hereof.

     (iii) The favorable opinion of Sullivan & Cromwell LLP, counsel for the Underwriters, dated such Date of Delivery, relating to the Option Shares to be purchased on such Date of Delivery and otherwise to the same effect as the opinion required by Section 7(e) hereof.

     (iv) A letter from Deloitte & Touche LLP, in form and substance satisfactory to the Representative and dated such Date of Delivery, substantially the same in form and substance as the letters furnished to the Representative pursuant to Sections 7(f) and (g) hereof.

          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 Underwriters.

          Any certificate or document signed by any officer of the Company and delivered to the Underwriters, or to counsel for the Underwriters, shall be deemed a representation and warranty by the Company to each Underwriter as to the statements made therein.

          The several obligations of the Underwriters to purchase Option Shares hereunder are subject to the satisfaction on and as of any Date of Delivery of the conditions set forth in this Section 7, except that, if any Date of Delivery is other than the First Delivery Date, the certificates, opinions and letters referred to in Sections 7(d) through 7(h) hereof shall be dated the Date of Delivery in question and the opinions called for by Sections 7(d) and 7(e) hereof shall be revised to reflect the sale of Option Shares.

          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 the Registration Statement or a post-effective amendment thereto to be declared effective before the offering of the Shares may commence, when notification of the effectiveness of the Registration Statement or such post-effective amendment has been released by the Commission.

          9. Default by One or More of the Underwriters. If, on either Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Shares which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of Firm Shares set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of Firm Shares set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Shares on such Delivery Date if the total number of Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of Shares to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of Shares which it agreed to purchase on such Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representative who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Shares to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representative do not elect to purchase the Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriters to purchase, and of the REIT to sell, the Option Shares) shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 13 and for indemnification and contribution as provided in Section 11. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 9, purchases Firm Shares which a defaulting Underwriter agreed but failed to purchase.

          Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other underwriters are obligated or agree to purchase the Shares of a defaulting or withdrawing Underwriter, either the Representative or the REIT (on behalf of the Company) may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

          10. [Reserved]

          11. Indemnification and Contribution. (a) The Company shall indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action or proceeding in respect thereof (including, but not limited to, any loss, claim, damage, liability or action or proceeding relating to purchases and sales of Shares), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability, action or proceeding arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (a) in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto or (b) in any blue sky application or other document prepared or executed by the REIT (on behalf of the Company) (or based upon any written information furnished by the Company) specifically for the purpose of qualifying any or all of the Shares under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (c) in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Shares, including any roadshow or investor presentations made to investors by the REIT (on behalf of the Company) (whether in person or electronically) (the “Marketing Materials”), (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, or in any Blue Sky Application or Marketing Materials any material fact required to be stated therein or necessary to make the statements therein not misleading (with respect to the Prospectus, in light of the circumstances under which they were made) or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Shares or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), and shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, 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 Company 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

25

Prospectus, the Registration Statement or the Prospectus, or in any such amendment or supplement, or in any Blue Sky Application or Marketing Materials, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representative by or on behalf of any Underwriter specifically for inclusion therein which information consists solely of the information specified in Section 11(f). The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

     (b) Each Underwriter shall indemnify and hold harmless the Company, its officers and employees, each of its trustees (including any person who, with his consent, is named in the Registration Statement as about to become a trustee of the REIT), and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action or proceeding in respect thereof, to which the Company or any such trustee, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action or proceeding arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, or (B) in any Blue Sky Application or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, or in any Blue Sky Application 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 such Underwriter furnished to the REIT (on behalf of the Company) through the Representative by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 11(f), and shall reimburse the Company and any such trustee, officer or controlling person for any legal or other expenses reasonably incurred by the Company or any such trustee, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action or proceeding as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company or any such trustee, officer, employee or controlling person.

     (c) [Reserved]

     (d) Promptly after receipt by an indemnified party under this Section 11 of notice of any claim or the commencement of any action or proceeding, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 11, notify the indemnifying party in writing of the claim or the commencement of that action or proceeding; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 11 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 11. If any such claim, action or proceeding 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, action or proceeding, the indemnifying party shall not be liable to the indemnified party under this Section 11 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Representative shall have the right to employ counsel to represent jointly the Representative and those other Underwriters and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under this Section 11 if (i) the Company and the Underwriters shall have so mutually agreed; (ii) the Company has failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriters; (iii) the Underwriters and their respective directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the Company; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriters or their respective directors, officers, employees or controlling persons, on the one hand, and the Company, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Company. 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, action or proceeding) 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 and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, 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 claim, action or proceeding, 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.

     (e) If the indemnification provided for in this Section 11 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 11(a) or 11(b) in respect of any loss, claim, damage or liability, or any claim, action or proceeding 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 or proceeding in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters 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 Company on the one hand and the Underwriters on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action or proceeding in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters 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 Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Shares purchased under this Agreement, on the other, 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 Company, on the one hand, or the Underwriters, on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take 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 or proceeding in respect thereof, referred to above in this Section shall be deemed to include, for purposes of this Section 11(e), 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 11(e), 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 such 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. The Underwriters’ obligations to contribute as provided in this Section 11(e) are several in proportion to their respective underwriting obligations and not joint.

     (f) The Underwriters severally, and not jointly, confirm and the Company acknowledges that (i) with respect to the public offering of the Shares by the Underwriters, the last sentence set forth on the cover page of, (ii) the names of the Underwriters and the number of Shares which they are each purchasing appearing immediately below the first paragraph under the caption “Underwriting” in, (iii) the first paragraph on concessions and reallowances appearing under the caption “Underwriting — Commissions and Expenses” in, and (iv) the first sentence appearing under the caption “Underwriting — Stabilization, Short Positions and Penalty Bids” in the Preliminary Prospectus, constitute the only information concerning such Underwriters furnished in writing to the REIT by or on behalf of the Underwriters specifically for inclusion in the Registration Statement and the Prospectus.

          12. Termination. The obligations of the Underwriters hereunder may be terminated by the Representative by notice given to and received by the REIT (on behalf of the Company) prior to delivery of and payment for any Shares if, prior to the time of delivery of such Shares, (i) any of the events described in Sections 7(i) or 7(j) shall have occurred, (ii) the Company shall have failed to have performed or complied with any of the agreements contemplated hereby and that are required to be performed or complied with by it hereunder, or (iii) if the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement.

          13. Reimbursement of Underwriters’ Expenses. If the REIT shall fail to tender the Shares for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company to perform any agreement on their part to be performed, or because any other condition to the Underwriters’ obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Shares, and upon demand the Company shall pay the full amount thereof to the Representative. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

          14. Research Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of its investment bankers. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies which may be the subject of the transactions contemplated by this Agreement.

          15. No Fiduciary Duty. The Company acknowledges and agrees that in connection with the Offering, sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Shares, and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with the Offering.

          16. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

     (a) if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to Lehman Brothers Inc., 745 Seventh Avenue, New York, N.Y. 10019, Attention: Syndicate Department, Fax: (646)  ###-###-####, with a copy, in the case of any notice pursuant to Section 11(d), to the Director of Litigation, Office of the General Counsel, Lehman Brothers Inc., 399 Park Avenue, 10th Floor, New York, NY 10022, Fax: (212)  ###-###-####;

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The REIT (on behalf of the Company) shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Underwriters by Lehman Brothers Inc.

          17. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company, and their respective personal representatives and successors. 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 Company contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control any Underwriter within the meaning of Section 15 of the Securities Act and (b) the indemnity agreement of the Underwriters contained in Section 11(b) of this Agreement shall be deemed to be for the benefit of any person controlling the Company 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 17, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

          18. Survival. The respective indemnities, representations, warranties and agreements of the Company, and the Underwriters 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. The provisions of Sections 11 and 13 hereof shall survive the termination or cancellation of this Agreement.

          19. Definition of the Terms “Business Day” and “Subsidiary". For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “subsidiary” has the meaning set forth in Rule 405 of the Rules and Regulations.

          20. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of New York.

          21. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

          If the foregoing is in accordance with your understanding, please indicate your acceptance in the space provided for that purpose below, whereupon this agreement and your acceptance shall constitute a binding agreement among the Company and the Underwriters.
