As of the Merger Effective Time, all such Shares, when so converted, shall no longer be outstanding and shall automatically be cancelled and retired, and each holder of a certificate formerly representing any such Shares shall cease to have any rights with respect thereto, except the right to receive any dividends or distributions in accordance withSection 2.3(c), certificates representing the Parent Shares into which such Shares are converted and any cash, without interest, in lieu of fractional shares to be issued or paid in consideration therefor upon the surrender of such certificate in accordance withSection 2.3(d).

As of the Merger Effective Time, all such Company Preferred Shares, when so converted, shall no longer be outstanding and shall automatically be cancelled and retired, and each holder of a certificate formerly representing any such Company Preferred Shares shall cease to have any rights with respect thereto, except the

right to receive the Preferred Merger Consideration upon surrender of such certificate in accordance withSection 2.3(d).

(e)Partnership Interests of OP Merger Sub. The general partner interests of OP Merger Sub issued and outstanding immediately prior to the OP Merger Effective Time shall automatically be cancelled and retired and shall cease to exist. The limited partner interests of OP Merger Sub issued and outstanding immediately prior to the OP Merger Effective Time shall remain issued, outstanding and unchanged as validly issued limited partner interests of the Surviving Partnership after the OP Merger Effective Time.

(f)Company Owned Company OP Units. Each unit of partnership interest in Company OP (the “Company OP Units”) that is outstanding immediately prior to the OP Merger Effective Time that is held by the Company or by any Company Subsidiary and each Company OP Unit that is outstanding immediately prior to the OP Merger Effective Time that is held by Parent, Merger Sub, OP Merger Sub or any other Subsidiary of Parent shall remain issued, outstanding and unchanged as validly issued partnership interests of the Surviving Partnership after the OP Merger Effective Time.

(g)Company OP Units. Each Company OP Unit issued and outstanding immediately prior to the OP Merger Effective Time (other than Company OP Units held by the Company, Company OP, any Company Subsidiary, Parent or any Subsidiary of Parent) shall automatically be converted into a fraction of a duly authorized, validly issued, fully paid and non-assessable Parent Share equal to the Exchange Ratio. As of the OP Merger Effective Time, all such Company OP Units, when so converted, shall no longer be outstanding and shall automatically be cancelled and retired, and each holder of any such Company OP Units shall cease to have any rights with respect thereto, except the right to receive any dividends or distributions in accordance withSection 2.3(c), certificates representing the Parent Shares into which such Company OP Units are converted and any cash, without interest, in lieu of fractional shares to be issued or paid in consideration therefor.

Section 2.3.Exchange of Certificates and Related Requirements.

(a)Exchange Fund. At the Merger Effective Time, Parent shall deposit, or shall cause to be deposited, with a banking or other financial institution selected by Parent and reasonably acceptable to the Company (the “Exchange Agent”), (i) for the benefit of the holders of Shares and Company OP Units, for exchange in accordance with thisArticle II, certificates representing the Parent Shares to be issued in connection with the Mergers pursuant toSection 2.2 and an amount of cash sufficient to permit the Exchange Agent to make the necessary payments of cash in lieu of fractional shares pursuant to thisSection 2.3 (such cash and certificates for Parent Shares, together with any dividends or distributions with respect thereto (relating to record dates for such dividends or distributions after the Merger Effective Time as provided inSection 2.3(c)), being hereinafter referred to as the “Exchange Fund”) in exchange for outstanding Shares and Company OP Units, and (ii) for the benefit of holders of Company Preferred Shares, for exchange in accordance with thisArticle II, cash in an amount sufficient to make the payments to such holders contemplated bySection 2.2(d) (such cash being hereinafter referred to as the “Preferred Exchange Fund”).

(b)Exchange Procedure. As soon as practicable after the Merger Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates representing Shares or Company Preferred Shares (the “Certificates”) or of Company OP Units (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and, (ii) if applicable, instructions for use in effecting the surrender of the Certificates in exchange for the consideration (and any unpaid distributions and dividends) contemplated bySection 2.2 and thisSection 2.3, including cash in lieu of fractional Parent Shares. Upon (i) surrender of a Certificate for cancellation to the Exchange Agent, if applicable, and (ii) delivery by such a holder of such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, such holder, if a holder of a Certificate representing Shares or of Company OP Units, shall be entitled to receive promptly in exchange therefor (x) a certificate representing that number of whole Parent Shares, (y) a check representing the amount of cash in lieu of fractional shares, if any, and (z) unpaid dividends and distributions with respect to the Parent Shares as provided for inSection 2.3(c), if any, that such holder has the right to receive in respect of the Certificate surrendered pursuant to the provisions of thisArticle II or in respect of such Company OP Units and, if a holder of a Certificate representing Company Preferred Shares, shall be entitled to receive promptly in exchange therefor the Preferred Merger Consideration in cash with respect to each Company Preferred Share represented by such Certificate, in all such cases after giving effect to any required withholding Tax. No interest will be paid or accrued on the cash payable to holders of Shares, Company OP Units or Company Preferred Shares. In the event of a transfer of ownership of Shares, Company OP Units or Company Preferred Shares that is not registered in the transfer records of the Company or Company OP, a certificate representing the proper number of Parent Shares, together with a check for the cash to be paid pursuant to thisSection 2.3, or the Preferred Merger Consideration, may be issued to such a transferee if such Certificate shall be properly endorsed or such Certificate or Company OP Units shall otherwise be in proper form for transfer and the transferee shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or Company OP Units or establish to the satisfaction of Parent that such Tax has been paid or is not applicable. Parent or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as Parent or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code or under any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

(c)Dividends. No dividends or other distributions declared with a record date after the Merger Effective Time on Parent Shares shall be paid with respect to any Shares represented by a Certificate until such Certificate is surrendered for exchange as provided herein or a Person claiming a Certificate to be lost, stolen or destroyed has complied with the provisions ofSection 2.5. Promptly following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole Parent Shares issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Merger Effective Time theretofore payable with respect to such whole Parent Shares and not paid, less the amount of any withholding Taxes which may be required

(d)No Fractional Securities. No fractional Parent Shares shall be issued pursuant hereto. In lieu of the issuance of any fractional Parent Shares, cash adjustments will be paid to holders in respect of any fractional Parent Shares that would otherwise be issuable, and the amount of such cash adjustment shall be equal to the product obtained by multiplying such holder’s fractional Parent Share that would otherwise be issuable by the closing price per share of Parent Shares on the New York Stock Exchange Composite Tape on the Closing Date as reported by The Wall Street Journal (Northeast edition) (or, if not reported thereby, any other authoritative source).

(e)No Further Ownership Rights in Shares. All Parent Shares issued or cash paid upon the surrender for exchange of Certificates or Company OP Units in accordance with the terms of thisArticle II (including any cash paid pursuant to thisSection 2.3) shall be deemed to have been issued in full satisfaction of all rights pertaining to the Shares or Company Preferred Shares theretofore represented by such Certificates or Company OP Units. At the Merger Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Entity of the Shares or Company Preferred Shares that were outstanding immediately prior to the Merger Effective Time. At the OP Merger Effective Time, the partnership interest transfer books of Company OP shall be closed, and there shall be no further registration of transfers on the partnership interest transfer books of the Surviving Partnership of the Company OP Units that were outstanding immediately prior to the OP Merger Effective Time. If, after the Merger Effective Time, Certificates are presented to the Surviving Entity or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in thisArticle II.

(f)Termination of Exchange Funds. Any portion of the Exchange Fund or Preferred Exchange Fund (including the proceeds of any investments thereof and any Parent Shares) which remains undistributed to the holders of Shares, Company Preferred Shares or Company OP Units, as applicable, for six months after the Merger Effective Time may be delivered to Parent, upon demand, and any holders of Shares, Company Preferred Shares or Company OP Units who have not theretofore complied with thisArticle II and the instructions set forth in the letter of transmittal mailed to such holders after the Merger Effective Time or the OP Merger Effective Time shall thereafter look only to Parent or its agent (subject to abandoned property, escheat or other similar laws) for payment of their Parent Shares or the Preferred Merger Consideration, as applicable, cash and unpaid dividends and distributions on Parent Shares deliverable in respect of each Share or Company OP Unit such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon.

(g)No Liability. None of Parent, Merger Sub, OP Merger Sub, the Company, Company OP or the Exchange Agent shall be liable to any Person in respect of any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

Section 2.4.Adjustment of Exchange Ratio. In the event that Parent changes or establishes a record date for changing the number of Parent Shares issued and outstanding as a result of a stock split, stock dividend, recapitalization, merger, subdivision, reclassification, combination or similar transaction with respect to the outstanding Parent Shares and the record date therefor shall be prior to the Effective Times, the Exchange Ratio applicable to the Mergers and any other calculations based on or relating to Parent Shares shall be appropriately adjusted to reflect such stock split, stock dividend, recapitalization, merger, subdivision, reclassification, combination or similar transaction.

Section 2.5.Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Exchange Agent, the posting by such Person of a bond, in such reasonable amount as Parent or the Exchange Agent may direct as indemnity against any claim that may be made against them with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Parent Shares, Preferred Merger Consideration and any cash in lieu of fractional Parent Shares to which the holders thereof are entitled pursuant toSection 2.3(b) and any dividends or other distributions to which the holders thereof are entitled pursuant toSection 2.3(c).

Each Employee Plan is listed onSection 3.14(a) of the Company Disclosure Letter.

(a) Except as would not reasonably be expected to have a Company Material Adverse Effect, no Group Member has any Liability under any Welfare Plan that provides for continuing benefits or coverage for any participant or any beneficiary of a participant after such participant’s termination of employment, except as may be required by Section 4980B of the Code or Section 601 et seq. of ERISA, or under any other applicable Legal Requirement.

(b) Except as would not reasonably be expected to have a Company Material Adverse Effect, each Employee Plan complies in all material respects with the applicable requirements of ERISA, the Code and any other applicable Legal Requirement governing such Employee Plan, and each Employee Plan has at all times been properly administered in all material respects in accordance with ERISA, the Code and all such other applicable Legal Requirements, and in accordance with its terms. Each Pension Plan that is intended to be qualified is qualified under Section 401(a) of the Code, has received a favorable determination letter from the Internal Revenue Service (“IRS”) stating that the form of such Pension Plan meets the applicable requirements of Section 401(a) of the Code and that the form of trust associated with such Pension Plan meets the applicable requirements for tax exemption under Section 501(a) of the Code and, except as would not reasonably be expected to have a Company Material Adverse Effect, no event has occurred that would jeopardize the qualified status of any such plan or the tax exempt status of any such trust under Sections 401(a) and Section 501(a) of the Code, respectively. Except as would not reasonably be expected to have a Company Material Adverse Effect, no lawsuits, claims (other than routine claims for benefits) or complaints to, or by, any Person or Governmental Agency with respect to any Employee Plan have been filed or are pending, the Company has received no notice of such a lawsuit, claim or complaint and, to the Knowledge of the Company, there is no fact or contemplated event that would be expected to give rise to any such lawsuit, claim (other than routine claims for benefits) or complaint with respect to any Employee Plan. Without limiting the foregoing, the following are true with respect to each Employee Plan, except as would not reasonably be expected to have a Company Material Adverse Effect:

(i) all Group Members have timely filed or caused to be filed every material return, report, statement, notice, declaration and other document required by ERISA, the Code or any other Legal Requirement or Governmental Agency (including, without limitation, the IRS and the U.S. Department of Labor) with respect to each such Employee Plan, each of such filings has been complete and accurate in all material respects and no Group Member has incurred any material Liability in connection with such filings;

(d) With respect to each Employee Plan, there has not occurred, and no Person or entity is contractually bound to enter into, any “prohibited transaction” within the meaning of Section 4975(c) of the Code or Section 406 of ERISA, which transaction is not exempt from Section 4975(c) of the Code or Section 406 of ERISA pursuant to a statutory or administrative exemption and that would subject a Group Member to a material excise tax or penalty.

(e) None of the Employee Plans is a multiemployer plan, as defined in Section 3(37) of ERISA (“Multiemployer Plan”). None of the Group Members or any trade or business (whether or not incorporated) which is or has ever been treated as a single employer with any Group Member under Section 414(b), (c), (m) or (o) of the Code (“ERISA Affiliate”) has incurred any liability due to a complete or partial withdrawal from a Multiemployer Plan or due to the termination or reorganization of a Multiemployer Plan, except for any such liability which has been satisfied in full, and no events have occurred and no circumstances exist that would be expected to result in any such Liability to any Group Member or ERISA Affiliate.

(f) None of the Employee Plans is a single-employer plan, as defined in Section 4001(a)(15) of ERISA, that is subject to Title IV of ERISA (“Title IV Plan”), and no Group Member or ERISA Affiliate has ever maintained a Title IV Plan.

Section 3.15.Employee Matters.

(a) A copy of each employee handbook of the Company has previously been made available to Parent. Such handbooks fairly and accurately summarize all material employee policies, vacation policies and payroll practices of the Company and the Company Subsidiaries. Neither the Company nor any of the Company Subsidiaries is a party to, or bound by, any collective bargaining agreement, contract or other agreement or understanding with a labor union or other labor organization, nor has the Company or any of the Company Subsidiaries agreed that any unit of their employees is appropriate for collective bargaining. No union or other labor organization has been certified as bargaining representative for any of the Company’s or the Company Subsidiaries’ employees. To the Knowledge of the Company there are no organizational efforts with respect to the formation of a collective bargaining unit presently being made or threatened involving employees of the Company or any of the Company Subsidiaries.

(b) Set forth onSection 3.15(b) of the Company Disclosure Letter is a true and complete list of Contracts which provide for all cash and non-cash payments, rights to property or other contract rights that will become payable, accelerated or vested to or in each executive officer or trustee (or person occupying a similar position in any other entity) of the Company or any Company Subsidiary as a result of the Mergers, to the extent the value of such payments and rights in the aggregate with respect to such person exceeds $25,000. Except as described onSection 3.15(b) of the Company Disclosure Letter, there is no employment or severance contract, or other agreement requiring payments, cancellation of indebtedness or other obligation to be made as a result of the consummation of any of the transactions contemplated by this Agreement, either alone or upon the occurrence of subsequent events, with respect to any executive officer or trustee of the Company or any the Company Subsidiary.

Section 3.16.Taxes.Except as set forth onSection 3.16 of the Company Disclosure Letter:

(a) Each of the Company and the Company Subsidiaries has timely filed all material Tax Returns (including all federal and state income Tax Returns) required to be filed by it with the appropriate Governmental Agency (taking into account all validly and duly obtained extensions of time to file) and has timely paid (or the Company has paid on its behalf) all material Taxes (including all federal and state income Taxes) required to be paid (whether or not shown on such filed Tax Returns). Such Tax Returns are true, correct and complete in all material respects. The Company has established in its books and records reserves or accrued liabilities or expenses that are adequate for payment of all Taxes for which the Company or any

Company Subsidiary is liable but are not yet due and payable. No material deficiency for any Taxes has been proposed, asserted or assessed by any Governmental Agency, or, to the Knowledge of the Company, threatened. Except as set forth onSection 3.16 of the Company Disclosure Letter, no Tax audits, examinations or similar proceedings involving Taxes are ongoing, scheduled to commence, or occurred on or after January 1, 2001.

(b) To the Knowledge of the Company, no claim has been made in writing by a Governmental Agency in a jurisdiction where the Company or any Company Subsidiary does not file Tax Returns such that the Company or the Company Subsidiary is or may be subject to taxation by that jurisdiction.

(c) Since the beginning of the Company’s short taxable year ended December 31, 2002 (the “First REIT Year”), the Company has taken all actions required to be taken in order to qualify as a “real estate investment trust” within the meaning of Section 856(a) of the Code (a “REIT”), including, but not limited to, paying all dividends required to be paid. Since the beginning of the First REIT Year, the Company has incurred no liability for Taxes under Sections 857(b), 860(c) or 4981 of the Code, including, without limitation, any tax arising from a prohibited transaction described in Section 857(b)(6) of the Code or any tax arising from “redetermined rents”, “redetermined deductions” and “excess interest” described in Section 857(b)(7) of the Code, and neither the Company nor any Company Subsidiary has incurred any liability for Taxes other than in the ordinary course of business consistent with past practice. No event has occurred, and no condition or circumstance exists, which presents a material risk that any material Tax described in the preceding sentence will be imposed upon the Company or any Company Subsidiary or presents a material risk that the Company’s status as a real estate investment trust will be jeopardized. The Company has not relied upon Sections 856(c)(6), 856(c)(7), or 856(g)(4) of the Code to qualify as a REIT.

(d) All material amounts of Taxes which the Company or Company Subsidiaries are required by any applicable Legal Requirement to withhold or collect, including Taxes required to have been withheld in connection with amounts paid or owing to an employee, independent contractor, creditor, shareholder or other third party and sales, gross receipts and use taxes, have been duly withheld or collected and, to the extent required, have been paid over to the proper Governmental Agency or are held in separate bank accounts for such purpose.

Parent maintains internal control over financial reporting (as defined in Rule 13a-15 or 15d-15, as applicable, under the Exchange Act).

material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting.

Parent has made available to Company a summary of all complaints or concerns relating to other matters made since the Applicable Date through Parent’s whistleblower hot line or equivalent system for receipt of employee concerns regarding possible violations of law. No attorney representing Parent or any Parent Subsidiary, whether or not employed by Parent or any Parent Subsidiary, has reported evidence of a violation of securities laws, breach of fiduciary duty or similar violation by the Parent or any of its officers, directors, employees or agents to Parent’s chief legal officer, audit committee (or other committee designated for the purpose) of the Board or the Board pursuant to the rules adopted pursuant to Section 307 of the Sarbanes-Oxley Act or any Parent policy contemplating such reporting.

If at any time prior to the Merger Effective Time, any information relating to Parent or the Company, or any of their respective Affiliates, officers, trustees or directors, should be discovered by Parent or the Company that should be set forth in an amendment or supplement to the Proxy Statement/Prospectus or the S-4 Registration Statement so that such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the holders of Company Common Shares and Company OP Units.

(ii) the Company and the Company Subsidiaries shall immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any of the foregoing (including any Acquisition Proposal) and use their reasonable best efforts to inform each Company Representative of the obligations undertaken in thisSection 6.6 and use their reasonable best efforts or, in the case of any Company Representative that constitutes a third party legal, accounting or financial advisor, their commercially reasonable efforts, to cause each such Company Representative to comply with such obligations; and

to be initiated or continued with the Company, and, as applicable, include in such notice the identity of the Person making such Acquisition Proposal, indication or request and the material terms of such Acquisition Proposal, indication or request; and (B) keep Parent informed on a prompt basis of the status and material terms of (including all material changes to the status or material terms of) any such Acquisition Proposal, indication or request.

(b) NotwithstandingSection 6.6(a), prior to obtaining the Company Shareholder Approval, the Board shall not be prohibited from furnishing information to, or entering into discussions or negotiations with, any Person that makes a bona fide written Acquisition Proposal to the Board after the date hereof which was not invited, initiated, solicited or encouraged, directly or indirectly, by the Company, any Company Subsidiary or any Company Representative on or after the date hereof if, and only to the extent that, (i) the Board concludes in good faith, based upon advice of its outside legal counsel, that such action is required to discharge the Board’s duties to the Company and its shareholders under Entity Law, (ii) a majority of the Board determines in good faith, after consultation with its financial advisors of nationally recognized reputation and outside legal counsel, that such Acquisition Proposal is reasonably likely to result in a Superior Acquisition Proposal, (iii) the Company complies with all of its obligations under this Agreement, (iv) prior to furnishing such information to, or entering into discussions or negotiations with, such Person, the Company provides written notice to Parent to the effect that it is furnishing information to, or entering into discussions with such Person, and (v) the Company enters into a confidentiality agreement with such Person the material terms of which are (without regard to the terms of such Acquisition Proposal) in all material respects no less favorable to the Company, and no less restrictive to the Person making such Acquisition Proposal, than those contained in the Confidentiality Agreement but which confidentiality agreement permits disclosure to Parent of the identity of the Person making such Acquisition Proposal and the material terms of such Acquisition Proposal.

(c) If, prior to obtaining the Company Shareholder Approval, the Board or any committee thereof intends: (i) to publicly approve or recommend, or propose to publicly approve or recommend, any Superior Acquisition Proposal, or (ii) to cause the Company to enter into any agreement with respect to any Superior Acquisition Proposal (other than any confidentiality agreement as contemplated bySection 6.6(b)) (a “Competing Agreement”), then at least five Business Days prior to taking such action: (A) the Company shall provide Parent with written notice advising Parent that the Board has received a Superior Acquisition Proposal that it intends to accept, specifying the material terms and conditions of such Superior Acquisition Proposal, identifying the Person or Persons making such Superior Acquisition Proposal and, if in writing, delivering to Parent the most recent draft of such definitive Competing Agreement and a summary of the material terms of any agreement to which the Company or any Company Subsidiary is a party that is integrated therewith, in its possession, and (B) the Company shall, and shall cause its financial and legal advisors to, negotiate in good faith with Parent for up to five (5) Business Days to make adjustments in the terms and conditions of this Agreement (the “Adjusted Terms”). If following the completion of such five (5) Business Day period the Board, in its sole judgment, has determined in good faith, after consultation with its financial advisors of nationally recognized reputation and outside legal counsel, that the Adjusted Terms are not at least as favorable to the Company shareholders as the Superior Acquisition Proposal (taking into account all financial and strategic considerations and

other relevant factors, including relevant legal, financial, regulatory and other aspects of such proposals, and the conditions, prospects and time required for completion of such proposal), then the Board or any committee thereof may: (i) publicly approve or recommend, or propose to approve or recommend, such Superior Acquisition Proposal; (ii) make an Adverse Recommendation or (iii) cause the Company to enter into a Competing Agreement with respect to such Superior Acquisition Proposal.

(d) For all purposes of this Agreement, “Superior Acquisition Proposal” means a bona fide unsolicited written proposal made by a third party to acquire, directly or indirectly, the Company and/or the Company Subsidiaries pursuant to a tender or exchange offer, merger, share exchange, consolidation or sale of all or substantially all of the assets of the Company and the Company Subsidiaries or otherwise (i) on terms which a majority of the Board determines in good faith, (A) after consultation with the Company’s financial advisors of nationally recognized reputation, are more favorable from a financial point of view to the Company shareholders than those provided for in the Merger (taking into account all the terms and conditions of the proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation) and (B) to be more favorable generally to the Company shareholders (taking into account all financial and strategic considerations and other relevant factors, including relevant legal, financial, regulatory and other aspects of such proposals, and the conditions, prospects and time required for completion of such proposal), (ii) for which financing, to the extent required, in the reasonable judgment of the Board is capable of being obtained and (iii) which the Board determines in good faith is reasonably capable of being consummated.

(e) Nothing in thisSection 6.6 or any other provision of this Agreement shall prohibit the Company or the Company’s Board from (a) taking and disclosing to its shareholders a position with respect to a tender or exchange offer by a third party pursuant to Rules 14d-9 and Rule 14e-2 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act (or any similar communication to shareholders in connection with the making or amendment of a tender or exchange offer) or (b) complying with its disclosure obligations under U.S. federal or state securities laws with regard to an Acquisition Proposal.

(f) Nothing in thisSection 6.6 shall (i) permit the Company to terminate this Agreement (except as expressly provided inArticle IX) or (ii) except as expressly provided herein, affect any other obligations of the Company under this Agreement.

(b) The Company will consult with and provide Parent the opportunity to review and comment upon all federal income Tax Returns required to be filed after the date hereof by the Company and Company OP with respect to Taxes, and shall not file any such federal income Tax Returns without the prior review and comment of Parent, which shall not be unreasonably delayed;provided,however, that the Company may file a Tax Return prior to receipt of comments from Parent if necessary to ensure such Tax Return is timely filed. From the date hereof until the Merger Effective Time, each of the Company and the Company Subsidiaries will duly and timely file all Tax Returns and other documents required by it to be filed with federal, state and local Tax authorities, subject to extensions permitted by law and properly granted by the appropriate authority;provided that such extensions do not adversely affect the Company’s status as a REIT under the Code, andprovided,further, that the Company notifies Parent that it or any of its Company Subsidiaries is availing itself of any federal or state extensions.

On or prior to the Closing Date, the Company will use its commercially reasonable efforts to cause each person identified as an “affiliate” in the Company Affiliate Letter to deliver a written agreement, in the form attached hereto asExhibit D.

(b) Each of Parent and the Company shall declare a dividend to their respective shareholders, the record date for which shall be the close of business on the last Business Day prior to the Merger Effective Time. The per share dividend amount payable by each party shall be an amount equal to such party’s most recent quarterly dividend rate, multiplied by the number of days elapsed since the last dividend record date through and

including the day prior to the day on which the Merger Effective Time occurs, and divided by the actual number of days in the calendar quarter in which such dividend is declared.

(c) In the event that a distribution with respect to the Company Common Shares and the Company Preferred Shares permitted by thisSection 6.9 (including pursuant toSection 6.9(b) above) has (i) a record date prior to the Effective Times and (ii) has not been paid as of the Effective Times, the holders of Company Common Shares and Company Preferred Shares shall be entitled to receive such distribution from the Company at the time such shares are exchanged pursuant toArticle II of this Agreement.

Section 6.10.Section 16 Matters.Each of the Company, Parent and Merger Sub shall use its commercially reasonable efforts to cause the transactions contemplated by this Agreement (including any dispositions of Company Common Shares, Company Preferred Shares, Pre-Conversion Options, Converted Options, Company OP Units or any derivative securities with respect to such securities in connection herewith) by any individual who is a trustee or officer of the Company, to be exempt under Rule 16b-3 promulgated under the Exchange Act, including any such actions specified in that certain No-Action Letter, dated January 12, 1999, issued by the SEC regarding such matters.

(c) The provisions of thisSection 8.2 shall not be terminated or modified after the Effective Times in such a manner as to adversely affect any Indemnified Party, his or her heirs and his or her personal representatives to which thisSection 8.2 applies, without the consent of such Indemnified Party, his or her heirs and his or her personal representatives.
