The Company and the Operating Partnership represent and warrant to, and agree with, each of the several Underwriters that: (a) The Company meets the requirements for use of Form S-3 under the Securities Act of 1933, as amended, and the rules and regulations of the Securities and Exchange Commission (the "Commission") thereunder (the "Act"). A registration statement on such Form (File No. 333-71807) with respect to the Securities, including a basic prospectus subject to completion, has been filed by the Company with the Commission under the Act, and one or more amendments to such registration statement may have been so filed. Such registration statement, as so amended, has been declared by the Commission to be effective under the Act. Such registration statement, as amended at the date of this Agreement, meets the requirements set forth in Rule 415(a)(1)(x) under the Act and complies in all other material respects with said Rule. A preliminary prospectus supplement relating to the Securities has been filed with the Commission pursuant to Rule 424(b) under the Act. The Company will next file with the Commission pursuant to Rule 424(b) under the Act a final prospectus supplement to the basic prospectus included in such registration statement, as so amended, describing the Securities and the offering thereof, in such form as has been provided to, or discussed with, and approved by the Representatives as provided in Section 5(a) of this Agreement. The Company may also file a related registration statement with the Commission pursuant to Rule 462(b) under the Act for the purpose of registering certain additional Securities, which registration shall be effective upon filing with the Commission. As used in this Agreement, the term "Registration Statement" means such registration statement initially filed relating to the Securities, as amended at the time when it was or is declared effective, including (A) all financial schedules and exhibits thereto and (B) all documents incorporated by reference therein filed under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the "Exchange Act"); the term "Preliminary Prospectus" means the basic prospectus subject to completion included in the Registration Statement or in any post-effective amendment thereto, including all documents incorporated by reference therein filed under the Exchange Act and as supplemented by the preliminary prospectus supplement relating to the Securities as first filed with the Commission pursuant to Rule 424(b) under the Act; the term "Prospectus" means such basic prospectus, as supplemented by the final prospectus supplement relating to the Securities as first filed with the Commission pursuant to Rule 424(b) under the Act, including all documents incorporated by reference therein filed under the Exchange Act; and the term "Prospectus Supplement" means such final prospectus supplement. Any reference in this Agreement to an "amendment or supplement" to any Preliminary Prospectus or the Prospectus or an "amendment" to any registration statement (including the Registration Statement) shall be deemed to include any document incorporated by reference therein that is filed with the Commission under the Exchange Act after the date of such Preliminary Prospectus, Prospectus or Registration Statement, as the case may be. For purposes of the preceding sentence, any reference to the "effective date" of an amendment to a Registration Statement shall, if such amendment is effected by means of the filing with the Commission under the Exchange Act of a document incorporated by reference in such registration statement, be deemed to refer to the date on which such document was so filed with the Commission. (b) The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus. When any Preliminary Prospectus or any amendment or supplement thereto was filed with the Commission, it (i) contained all statements required to be stated therein in accordance with, and complied in all material respects with the requirements of, the Act and the Exchange Act and (ii) did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. When the Registration Statement or any amendment thereto was or is declared effective, it (i) contained or will contain all statements required to be stated therein in accordance with, and complied or will comply in all material respects with the requirements of, the Act and the Exchange Act and (ii) did not or will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. When the Prospectus or any amendment or supplement to the Prospectus is filed with the Commission 2 pursuant to Rule 424(b), on the date when the Prospectus is otherwise amended or supplemented and on the Firm Closing Date and any Option Closing Date (both as hereinafter defined), the Prospectus, as amended or supplemented at any such time, (i) contained or will contain all statements required to be stated therein in accordance with, and complied or will comply in all material respects with the requirements of, the Act and the Exchange Act and (ii) did not or will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(c) No stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and no proceeding for that purpose has been instituted, or to the knowledge of the Company, threatened by the Commission or by the state securities authority of any jurisdiction. No order preventing or suspending the use of the Prospectus has been issued and no proceeding for that purpose has been instituted or, to the knowledge of the Company, threatened by the Commission or by the state securities authority of any jurisdiction.

(z) Neither the Company nor any of its Subsidiaries is or will conduct its operations in a manner that will subject it to registration as an investment company under the Investment Company Act of 1940, as amended, and this transaction will not cause the Company or any Subsidiary to become an investment company subject to registration under such Act.

All statements in the Prospectus (or, if the Prospectus is not in existence, the most recent Preliminary Prospectus) regarding the Company's qualification as a REIT are true, complete and correct in all material respects. (ee) Each certificate signed by any officer or authorized representative of the Company or any Subsidiary and delivered to the Representatives or counsel for the Underwriters shall be deemed to be a representation and warranty by the Company or any Subsidiary to each Underwriter as to the matters covered thereby.

(hh) The Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (1) transactions are executed in accordance with management's general or specific authorizations; (2) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (3) access to assets, financial and corporate books and records is permitted only in accordance with management's general or specific authorization; and (4) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(kk) The Company has timely filed all documents required to be filed by it under the Exchange Act. (ll) No relationship, direct or indirect, exists between or among the Company or the Subsidiaries on the one hand, and the trustees, directors, officers, shareholders, customers or suppliers of the Company or the Subsidiaries on the other hand, which is required by the Act or the rules of the NASD to be described in the Registration Statement and the Prospectus which is not so described. (mm) Except as otherwise disclosed in the Prospectus under "Our Office Portfolio - Pending Acquisition," there are no contracts, agreements, letters of intent, understandings or any other documents relating to the pending acquisition of any real property by the Company or the Operating Partnership that are required to be disclosed in the Prospectus. 3. PURCHASE, SALE AND DELIVERY OF THE SECURITIES. (a) On the basis of the representations, warranties, agreements and covenants herein contained and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase from the Company, at a purchase price of $24.0625 per share, the number of Firm Securities set forth opposite the name of such Underwriter in Schedule I hereto. In order the meet the requirements for listing the Securities on the NYSE, the Underwriters undertake to sell (i) the Securities to ensure a minimum of 100 beneficial holders with a minimum of 100,000 Securities outstanding and (ii) sufficient Securities so that following the offering of the Securities, the Securities have a minimum aggregate market value of at least $2.0 million. One or more certificates in definitive form for the Firm Securities that the several Underwriters have agreed to purchase hereunder, and in such denomination or denominations and registered in such name or names as the Representatives request upon notice to the Company at least 48 hours prior to the Firm Closing Date, shall be delivered, with transfer taxes thereon duly paid, by or on behalf of the Company to Prudential Securities Incorporated through the facilities of The Depository Trust Company ("DTC"), for the respective accounts of the Underwriters, against payment by or on behalf of the Underwriters of the purchase price therefor by wire transfer in same-day funds (the "Wired Funds") to the account of the Company. Such delivery of and payment for the Firm Securities shall be made at 9:30 A.M., New York time, on July 7, 1999, or at such other place, time or date as the Representatives and the Company may agree upon or as the Representatives may determine pursuant to Section 9 hereof, such time and date of delivery against payment being herein referred to as the "Firm Closing Date." The Company will make such certificate or certificates for the Firm Securities available for inspection by the Representatives at the offices of DTC or its designated custodian at least 24 hours prior to the Firm Closing Date. (b) For the purpose of covering any over-allotments in connection with the distribution and sale of the Firm Securities as contemplated by the Prospectus, the Company hereby grants to the several Underwriters an option to purchase, severally and not jointly, the Option Securities. The purchase price to be paid for any Option Securities shall be the same price per share as the price per share for the Firm Securities set forth above in paragraph (a) of this Section 3 , plus if the purchase and sale of any Option Securities takes place after the Firm Closing Date and after the Firm Securities are trading "ex-dividend," an amount equal to the dividend payable on such Option Securities. The option granted hereby may be exercised as to 12 all or any part of the Option Securities from time to time within thirty days after the date of the Prospectus (or, if such 30th day shall be a Saturday or Sunday or a holiday, on the next business day thereafter when the NYSE is open for trading). The Underwriters shall not be under any obligation to purchase any of the Option Securities prior to the exercise of such option. The Representatives may from time to time exercise the option granted hereby by giving notice in writing or by telephone (confirmed in writing) to the Company setting forth the aggregate principal amount of Option Securities as to which the several Underwriters are then exercising the option and the date and time for delivery of and payment for such Option Securities. Any such date of delivery shall be determined by the Representatives but shall not be earlier than two business days or later than five business days after such exercise of the option and, in any event, shall not be earlier than the Firm Closing Date. The time and date set forth in such notice, or such other time on such other date as the Representatives and the Company may agree upon or as the Representatives may determine pursuant to Section 9 hereof, is herein called the "Option Closing Date" with respect to such Option Securities. Upon exercise of the option as provided herein, the Company shall become obligated to sell to each of the several Underwriters, and, subject to the terms and conditions herein set forth, each of the Underwriters (severally and not jointly) shall become obligated to purchase from the Company, the same percentage of the total number of the Option Securities as to which the several Underwriters are then exercising the option as such Underwriter is obligated to purchase of the aggregate number of Firm Securities, as adjusted by the Representatives in such manner as they deem advisable to avoid fractional Shares. If the option is exercised as to all or any portion of the Option Securities, one or more certificates in definitive form for such Option Securities, and payment therefor, shall be delivered on the related Option Closing Date in the manner, and upon the terms and conditions, set forth in paragraph (a) of this Section 3, except that reference therein to the Firm Securities and the Firm Closing Date shall be deemed, for purposes of this paragraph (b), to refer to such Option Securities and Option Closing Date, respectively. The documents to be delivered on the Firm Closing Date or any Option Closing Date on behalf of the parties hereto pursuant to Section 7 of this Agreement shall be delivered at the offices of Rogers & Wells LLP, 200 Park Avenue, New York, New York 10166 and the Securities shall be delivered at the offices of DTC, all on the Firm Closing Date or such Option Closing Date, as the case may be. (c) The Company hereby acknowledges that the wire transfer by or on behalf of the Underwriters of the purchase price for any Securities does not constitute closing of a purchase and sale of the Securities. Only execution and delivery of a receipt for Securities by the Underwriters indicates completion of the closing of a purchase of the Securities from the Company. Furthermore, in the event that the Underwriters wire funds to the Company prior to the completion of the closing of a purchase of Securities, the Company hereby acknowledges that until the Underwriters execute and deliver a receipt for the Securities, by facsimile or otherwise, the Company will not be entitled to the Wired Funds and shall return the Wired Funds to the Underwriters as soon as practicable (by wire transfer of same-day funds) upon demand. In the event that the closing of a purchase of Securities is not completed and the Wired Funds are not returned by the Company to the Underwriters on the same day the Wired Funds were received by the Company, the Company agrees to pay to the Underwriters in respect of each day the Wired Funds are not returned by it, in same-day funds, interest on the amount of such Wired Funds in an amount representing the Underwriters' cost of financing as reasonably determined by Prudential Securities Incorporated. 13 (d) It is understood that any of you, individually and not as one of the Representatives, may (but shall not be obligated to) make payment on behalf of any Underwriter or Underwriters for any of the Securities to be purchased by such Underwriter or Underwriters. No such payment shall relieve such Underwriter or Underwriters from any of its or their obligations hereunder. 4. OFFERING BY THE UNDERWRITERS. Upon your authorization of the release of the Firm Securities, the several Underwriters propose to offer the Firm Securities for sale to the public upon the terms set forth in the Prospectus. 5. COVENANTS OF THE COMPANY AND THE OPERATING PARTNERSHIP. The Company and the Operating Partnership covenant and agree with each of the Underwriters that: (a) The Company will use its best efforts to cause the Registration Statement, if not effective at the time of execution of this Agreement, and any amendments thereto to become effective as promptly as possible. If required, the Company will file the Prospectus or the Prospectus Supplement, as the case may be, and any amendment or supplement thereto with the Commission in the manner and within the time period required by Rule 424(b) under the Act. During any time when a prospectus relating to the Securities is required to be delivered under the Act, the Company (i) will comply with all requirements imposed upon it by the Act and the Exchange Act to the extent necessary to permit the continuance of sales of or dealings in the Securities in accordance with the provisions hereof and of the Prospectus, as then amended or supplemented, and (ii) will not file with the Commission the Prospectus, any amendment or supplement thereto or any amendment to the Registration Statement or any Rule 462(b) Registration Statement of which the Representatives shall not previously have been advised and furnished with a copy for a reasonable period of time prior to the proposed filing and as to which filing the Representatives shall not have given their consent. The Company will prepare and file with the Commission, in accordance with the rules and regulations of the Commission, promptly upon request by the Representatives or counsel for the Underwriters, any amendments to the Registration Statement or amendments or supplements to the Prospectus that may be necessary or advisable in connection with the distribution of the Securities by the several Underwriters, and will use its best efforts to cause any such amendment to the Registration Statement to be declared effective by the Commission as promptly as possible. The Company will advise the Representatives, promptly after receiving notice thereof, of the time when the Registration Statement or any amendment thereto has been filed or declared effective or the Prospectus or any amendment or supplement thereto has been filed and will provide evidence satisfactory to the Representatives of each such filing or effectiveness. (b) The Company will advise the Representatives, promptly after receiving notice or obtaining knowledge thereof and, if requested by the Underwriters, to confirm such advice in writing, of (i) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement or any post-effective amendment thereto or any order directed at any document incorporated by reference in the Registration Statement or the Prospectus or any amendment or supplement thereto or any order preventing or suspending the use of any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, (ii) the suspension of the qualification of the Securities for offering or sale in any jurisdiction, (iii) the institution, threatening or contemplation of any proceeding for any such purpose, (iv) the effectiveness of any amendment to the Registration Statement or any Rule 462(b) Registration Statement, the transmittal to the Commission for filing of any Preliminary Prospectus or Prospectus or other supplement or amendment thereto 14 to be filed pursuant to the Act, any request made by the Commission for amending the Registration Statement or any Rule 462(b) Registration Statement, for amending or supplementing any Preliminary Prospectus or the Prospectus or for additional information or (v) the happening of any event during the period referred to in Section 5(d) below which makes any statement of a material fact made in the Registration Statement, the Preliminary Prospectus or Prospectus untrue or which requires any additions to or changes in the foregoing in order to make the statements therein not misleading. The Company will use its best efforts to prevent the issuance of any such stop order and, if any such stop order is issued, to obtain the withdrawal or lifting thereof as promptly as possible. (c) The Company will arrange for the registration or qualification of the Securities for offering and sale under the applicable state securities or blue sky laws and real estate syndication laws of such jurisdictions as the Representatives may designate and will continue such registration or qualifications in effect for as long as may be necessary to complete the distribution of the Securities and to file such consents to service of process or other documents as may be necessary in order to effect such registration or qualification; PROVIDED, HOWEVER, that in connection therewith the Company shall not be required to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction. (d) If, at any time prior to the later of (i) the final date when a prospectus relating to the Securities is required to be delivered under the Act or (ii) the Option Closing Date, any event occurs as a result of which the Prospectus, as then amended or supplemented, would include any 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, or if for any other reason it is necessary at any time to amend or supplement the Prospectus to comply with the Act or the Exchange Act or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, the Company will promptly notify the Representatives thereof and, subject to Section 5(a) hereof, will prepare and file with the Commission, at the Company's expense, an amendment to the Registration Statement, or an amendment or supplement to the Prospectus that corrects such statement or omission or effects such compliance. (e) The Company will, without charge, provide (i) to the Representatives and to counsel for the Underwriters a signed copy of the registration statement originally filed with respect to the Securities and each amendment thereto (in each case including exhibits thereto), (ii) to each other Underwriter, a conformed copy of such registration statement or any Rule 462(b) Registration Statement and each amendment thereto (in each case without exhibits thereto) and (iii) so long as a prospectus relating to the Securities is required to be delivered under the Act, as many copies of each Preliminary Prospectus or the Prospectus or any amendment or supplement thereto as the Representatives may reasonably request; without limiting the application of clause (iii) of this sentence, the Company, not later than (A) 6:00 PM, New York City time, on the date of determination of the public offering price, if such determination occurred at or prior to 10:00 AM, New York City time on such date or (B) 2:00 PM, New York City time, on the business day following the date of determination of the public offering price, if such determination occurred after 10:00 AM, New York City time, on such date, will deliver to the Underwriters, without charge, as many copies of the Prospectus and any amendment or supplement thereto as the Representatives may reasonably request for purposes of confirming orders that are expected to settle on the Firm Closing Date.

(g) The Company will apply the net proceeds from the sale of the Securities as set forth under "Use of Proceeds" in the Prospectus. (h) The Company will not, at any time, directly or indirectly, (i) take any action designed to cause or to result in, or that has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities or (ii) (A) sell, bid for, purchase, or pay anyone any compensation for soliciting purchases of, the Securities or (B) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the Company. (i) If at any time during the first to conclude of the 25-day period after the Registration Statement becomes effective or the period prior to the Option Closing Date, any rumor, publication or event relating to or affecting the Company shall occur as a result of which in your opinion the market price of the Preferred Shares has been or is likely to be materially affected (regardless of whether such rumor, publication or event necessitates a supplement to or amendment of the Prospectus), the Company will, after notice from you advising the Company to the effect set forth above, forthwith prepare, consult with you concerning the substance of, and disseminate a press release or other public statement, reasonably satisfactory to you, responding to or commenting on such rumor, publication or event. (j) If the Company elects to rely on Rule 462(b), the Company shall both file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) and pay the applicable fees or give irrevocable instructions for the payment of such fees in accordance with Rule 111 promulgated under the Act by the earlier of (i) 10:00 P.M. Eastern time on the date of this Agreement and (ii) the time confirmations are sent or given, as specified by Rule 462(b)(2). (k) The Company will use its best efforts to cause the Securities to be duly authorized for listing by the NYSE prior to the Firm Closing Date and to maintain the listing of the Securities on the NYSE for a period of two years after the Firm Closing Date and thereafter unless the Company's Board of Trustees determines that it is no longer in the best interests of the Company for the Securities to continue to be so listed.

(ix) To such counsel's knowledge, the issuance, offering and sale of the Securities to the Underwriters by the Company pursuant to this Agreement, the execution, delivery, performance and the compliance by the Company and the Operating Partnership with this Agreement and the consummation of the other transactions herein contemplated do not and will not (A) require the consent, approval, authorization, registration, order, filing or qualification of or with any court, regulatory body, administrative agency or other governmental authority, except such as have been obtained and such as may be required under state securities or blue sky laws or real estate syndication laws of the various states in connection with the purchase and distribution of the securities by the Underwriters, except such as are related to the filing of the Articles Supplementary with the SDAT, which filing with the SDAT will be made prior to the Firm Closing Date or as may be required under the Act or other securities laws or bylaws and rules of the NASD, or the listing requirements of the NYSE or such as have been received prior to the date of the opinion, or (B) conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a default under (and there is no event which, but for the passage of time or the giving of notice, or both, 20 would constitute a default under any of the foregoing), (x) the declaration of trust, charter, bylaws, partnership agreement or other organizational document of the Company or the Subsidiaries, (y) any document (as in effect on the date of such opinion) listed on Schedule IV to which the Company or any of the Subsidiaries is a party or by which the Company or any of such Subsidiaries or their respective property is bound (it being understood that such counsel may assume compliance with the financial covenants contained in any such document), (C) violate or conflict with any applicable law, rule or administrative regulation of the United States, the State of Delaware or the State of Maryland, or (D) any order or administrative or court decree of which such counsel is aware, except in each case for conflicts, breaches, violations or defaults that in the aggregate would not have a Material Adverse Effect; (x) The Registration Statement is effective under the Act; the Prospectus or the Prospectus Supplement, as the case may be, has been filed with the Commission in the manner and within the time period required by Rules 424(b); and no stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto and no order of the Commission directed at any document incorporated by reference in the Registration Statement or the Prospectus or any amendment or supplement thereto has been issued, and no proceedings for that purpose have been instituted or threatened or, to the best knowledge of such counsel, are contemplated by the Commission; (xi) The Registration Statement originally filed with respect to the Securities and each amendment thereto and any Rule 462(b) Registration Statement, as of the date hereof and at the time it became effective, the Prospectus, as of its date or when any amendment or supplement is filed with the Commission (in each case, including the documents incorporated by reference therein but not including the financial statements and other financial information contained therein, as to which such counsel need express no opinion) comply as to form in all material respects with the applicable requirements of the Act and the Exchange Act; (xii) The authorized shares of beneficial interest of the Company conform as to legal matters in all material respects to the description thereof contained in the Prospectus or the description contained in the Articles Supplementary; (xiii) To the knowledge of such counsel, neither the Company nor any of the Subsidiaries is in violation of its respective charter, declaration of trust, bylaws, partnership agreement or other organizational document, as the case may be, and, to such counsel's knowledge, neither the Company nor any of such Subsidiaries is in default in the performance or observance of (and there is no event which, but for the passage of time or the giving of notice, or both, would constitute a default under any of the foregoing), any obligation, agreement, covenant or condition contained in any document (as in effect on the date of such opinion) listed on Schedule IV to which the Company or any of such Subsidiaries is a party or by which the Company or any of such Subsidiaries or their respective property is bound (it being understood that such counsel may assume compliance with the financial covenants contained in any such document), except in each case for violations or defaults which in the aggregate are not reasonably expected to have a Material Adverse Effect; (xiv) The Company and the Subsidiaries are not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as 21 described in the Prospectus, will not be required to be registered as an "investment company" under the Investment Company Act of 1940, as amended; and (xv) To the best of such counsel's knowledge, there are no contracts or agreements between the Company and any person granting such person the right to require the Company to include securities of the Company held by such person with the Securities registered pursuant to the Registration Statement. In addition, Morgan, Lewis & Bockius LLP shall confirm that the opinion filed as Exhibit 8.1 to the Registration Statement is true and correct as of the date thereof and permit the Underwriters to rely on such opinion as if it were addressed to the Underwriters.

On the basis thereof (relying as to materiality to the extent it deems appropriate upon the opinions of officers and other representatives of the Company), but without independent verification by such counsel of, and without passing upon or assuming any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus or any amendments or supplements thereto, no facts have come to the attention of such counsel that lead them to believe that (i) the Registration Statement, at the time such Registration Statement became effective, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading or (ii) the Prospectus, as of its date or at the Firm Closing Date contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that such counsel need express no opinion with respect to the financial statements, schedules and other financial and statistical data included in the Registration Statement or the Prospectus). In giving its opinion, such counsel shall expressly limit their opinion to matters of Federal and Pennsylvania law and the Revised Uniform Limited Partnership Act, the General Corporation Law of the State of Delaware and Title 8 of the Corporations and Associations Article of the Annotated Code of Maryland and may rely without independent verification (A) as to all matters of fact, upon certificates and written statements of officers, trustees, directors, partners and employees of and accountants for the Company and the Subsidiaries and (B) as to the good standing and qualification of the Company and the Subsidiaries, to do business in any state or jurisdiction, upon certificates of appropriate government officials or opinions of counsel in such jurisdictions.

References to the Registration Statement and the Prospectus in this paragraph (f) with respect to either letter referred to above shall include any amendment or supplement thereto at the date of such letter.

INDEMNIFICATION AND CONTRIBUTION. (a) The Company and the Operating Partnership agree to indemnify and hold harmless each Underwriter, its directors, its officers and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or such controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, judgments or liabilities (including, without limitation, any reasonable legal or other expenses incurred in connection with investigating or defending any matter, including any action, that could give rise to any such losses, claims, damages, liabilities or judgments) arise out of or are based upon: (i) Any untrue statement or alleged untrue statement made by the Company or the Operating Partnership in Section 2 of this Agreement, 25 (ii) Any untrue statement or alleged untrue statement of any material fact contained in (A) the Registration Statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto or (B) any application or other document, or any amendment or supplement thereto, executed by the Company or the Operating Partnership or based upon written information furnished by or on behalf of the Company or the Operating Partnership filed in any jurisdiction in order to qualify the Securities under the securities or blue sky laws thereof or filed with the Commission or any securities association or securities exchange (each an "Application"), (iii) The omission or alleged omission to state in the Registration Statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or any Application a material fact required to be stated therein or necessary to make the statements therein not misleading or (iv) Any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials prepared by the Company or the Operating Partnership or based upon written information furnished by or on behalf of the Company or the Operating Partnership (including, without limitation, slides, videos, films, tape recordings) used in connection with the marketing of the Securities, including, without limitation, statements communicated to securities analysts employed by the Underwriters and will reimburse, as incurred, each Underwriter and each such controlling person for any legal or other expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or any Application in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein; and PROVIDED, FURTHER, that the Company will not be liable to any Underwriter, its directors, officers or any person controlling such Underwriter with respect to any such untrue statement or omission made in any Preliminary Prospectus that is corrected in the Prospectus (or any amendment or supplement thereto) if the person asserting any such loss, claim, damage or liability purchased Securities from such Underwriter but was not sent or given a copy of the Prospectus (as amended or supplemented), other than the documents incorporated by reference therein, at or prior to the written confirmation of the sale of such Securities to such person in any case where such delivery of the Prospectus (as amended or supplemented) is required by the Act, unless such failure to deliver the Prospectus (as amended or supplemented) was a result of noncompliance by the Company with Section 5(a) and (d) of this Agreement. This indemnity agreement will be in addition to any liability which the Company may otherwise have. The Company will not, without the prior written consent of the Underwriter or Underwriters purchasing, in the aggregate, more than fifty percent (50%) of the Securities, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not any such Underwriter, its directors, officers or any person who controls any such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding), unless such settlement, compromise or consent includes an 26 unconditional release of all of the Underwriters and such controlling persons from all liability arising out of such claim, action, suit or proceeding. (b) Each Underwriter, severally and not jointly, will indemnity and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, it any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or any Application or (ii) the omission or the alleged omission to state therein a material fact required to be stated in the Registration Statement or any amendment thereto, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or any Application or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein; and, subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability or any action in respect thereof. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 8. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; PROVIDED, HOWEVER, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by 27 the Representatives in the case of paragraph (a) of this Section 8, representing the indemnified parties under such paragraph (a) who are parties to such action or actions) or (ii) the indemnifying party does not promptly retain counsel satisfactory to the indemnified party or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the consent of the indemnifying party. (d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 8 is unavailable or insufficient, for any reason, to hold harmless an indemnified party in respect of any losses, claims, damages, judgments or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, judgments or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Securities or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions 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 shall be deemed to be in the same proportion as the total proceeds from the offering (after deducting underwriting discounts and commissions and before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the parties' relative intents, knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. The Company and the Underwriters agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to above in this paragraph (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such indemnified party in connection with investigating or defending any action or claim. Notwithstanding any other provision of this paragraph (d), no Underwriter shall be obligated to make contributions hereunder that in the aggregate exceed the total public offering price of the Securities purchased by such Underwriter under this Agreement, less the aggregate amount of any damages that such Underwriter has otherwise been required to pay in respect of the same or any substantially similar claim, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute hereunder are several in proportion to their respective underwriting obligations and not joint, and contributions among Underwriters shall be governed by the provisions of the Prudential Securities Incorporated Master Agreement Among Underwriters. For purposes of this paragraph (d), each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to 28 contribution as such Underwriter, and each director 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 Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of the Underwriters or any persons controlling the Underwriters, the Company, its trustees or officers, or any person controlling the Company, (ii) acceptance of any Securities and payment therefor hereunder, and (iii) any termination of this Agreement. Any successors to the Underwriters or any persons controlling the Underwriters, or to the Company, its trustees or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8. 9. DEFAULT OF UNDERWRITERS. If on the Firm Closing Date or on an Option Closing Date, as the case may be, any one or more Underwriters default in their obligations to purchase Firm Securities or Option Securities hereunder and the aggregate number of such Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase is ten percent or less of the aggregate number of Firm Securities or Option Securities to be purchased by all of the Underwriters at such time hereunder, the other Underwriters may make arrangements satisfactory to the Representatives for the purchase of such Securities by other persons (who may include one or more of the non-defaulting Underwriters, including the Representatives), but if no such arrangements are made by the Firm Closing Date or the related Option Closing Date, as the case may be, the other Underwriters shall be obligated severally in proportion to their respective commitments hereunder to purchase the Firm Securities or Option Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase. If one or more Underwriters so default with respect to an aggregate number of Securities that is more than ten percent of the aggregate number of Firm Securities or Option Securities, as the case may be, to be purchased by all of the Underwriters at such time hereunder, and if arrangements satisfactory to the Representatives are not made within 36 hours after such default for the purchase by other persons (who may include one or more of the non-defaulting Underwriters, including the Representatives) of the Securities with respect to which such default occurs, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company other than as provided in Section 10 hereof. In the event of any default by one or more Underwriters as described in this Section 9, the Representatives shall have the right to postpone the Firm Closing Date or the Option Closing Date, as the case may be, established as provided in Section 3 hereof for not more than seven business days in order that any necessary changes may be made in the arrangements or documents for the purchase and delivery of the Firm Securities or Option Securities, as the case may be. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section 9. Nothing herein shall relieve any defaulting Underwriter from liability for its default. 10. SURVIVAL. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Company, its officers and the several Underwriters set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Company, any of its officers or directors, any Underwriter or any controlling person 29 referred to in Section 8 hereof and (ii) delivery of and payment for the Securities. The respective agreements, covenants, indemnities and other statements set forth in Sections 6 and 8 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 11. TERMINATION. (a) This Agreement may be terminated with respect to the Firm Securities or any Option Securities in the sole discretion of the Representatives by notice to the Company given prior to the Firm Closing Date or the related Option Closing Date, respectively, in the event that the Company or the Operating Partnership shall have failed, refused or been unable to perform all obligations and satisfy all conditions on their part to be performed or satisfied hereunder at or prior thereto or, if at or prior to the Firm Closing Date or such Option Closing Date, respectively, (i) The Company or any of its Subsidiaries shall have, in the sole judgment of the Representatives, sustained any material loss or interference with their respective businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any labor dispute or any legal or governmental proceeding or since the respective dates as of which information is given in the Registration Statement and the Prospectus, there shall have been a Material Adverse Effect, except in each case as described in or contemplated by the Prospectus (exclusive of any amendment or supplement thereto); (ii) Trading in the Common Shares of Beneficial Interest of the Company shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE shall have been suspended, or minimum or maximum prices shall have been established on such exchange or the suspension or material limitation of trading of any securities of the Company on any exchange or in the over the counter market; (iii) A banking moratorium shall have been declared by New York or United States authorities; or (iv) There shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power, (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or (C) any other calamity or crisis or material adverse change in general economic, political or financial conditions having an effect on the U. S. financial markets that, in the sole judgment of the Representatives, makes it impractical or inadvisable to proceed with the public offering or the delivery of the Securities as contemplated by the Registration Statement, as amended as of the date hereof. (b) Termination of this Agreement pursuant to this Section 11 shall be without liability of any party to any other party except as provided in Section 10 hereof. 12.
