(c) Subject to the Company Parties’ compliance with the provisions of this Section 7.04, and only prior to the Company Shareholder Approval, following the receipt by the Company or any Subsidiary of a written Acquisition Proposal, the Company Board may (directly or through Representatives) (I) contact such Person and its advisors solely for the purpose of clarifying the proposal and any material terms thereof and the conditions to consummation, so as to determine whether the proposal for an Acquisition Proposal is reasonably likely to result in a Superior Proposal and (II) if the Company Board determines in good faith following consultation with its legal and financial advisors that such Acquisition Proposal is reasonably likely to result in a Superior Proposal, the Company Board thereafter may (i) furnish non-public information with respect to the Company and the Subsidiaries to the Person who made such proposal (provided that the Company (A) has previously or concurrently furnished such information to Parent and (B) shall furnish such information pursuant to a confidentiality agreement which is at least as favorable to the Company as the Confidentiality Agreement), (ii) participate in negotiations regarding such proposal, (iii) following receipt of a written Acquisition Proposal that constitutes a Superior Proposal, (x) recommend that the Company’s shareholders approve such Superior Proposal and, in connection therewith, effect a Change in Recommendation and

- 56-

(y) authorize the Company to enter into a definitive agreement providing for the implementation of such Superior Proposal; provided that the Company shall not enter into any such agreement unless this Agreement shall have been terminated by the Company in accordance with Section 9.01(h). Nothing in this Section 7.04 or elsewhere in this Agreement shall prevent the Company Board from (i) at any time prior to obtaining the Company Stockholder Approval and other than in response to an Acquisition Proposal, effecting a Change in Recommendation in the event that the Company Board has determined in good faith that the failure to take such action would be inconsistent with its duties to the shareholders of the Company under applicable Law, or (ii) taking and disclosing to the Company shareholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act with respect to an Acquisition Proposal or from making any required disclosure to the Company’s shareholders under applicable Law, including Rule 14d-9 promulgated under the Exchange Act or Item 1012(a) of Regulation M-A; provided, however, that neither the Company nor the Company Board shall be permitted to recommend that the Company shareholders tender any securities in connection with any tender or exchange offer (or otherwise approve, endorse or recommend any Acquisition Proposal) or withdraw or modify the Company Recommendation, unless in each case such tender or exchange offer constitutes a Superior Proposal and, in connection therewith, effects a Change in Recommendation. In addition, nothing in this Section 7.04(c) shall prohibit the Company Parties from taking any action that any court of competent jurisdiction orders the Company Parties to take.

(d) The Company shall not take any action to exempt any Person from the restrictions contained in Article VII of the Company Charter or otherwise cause any of such restrictions not to apply unless such actions are taken in connection with a termination of this Agreement in accordance with Section 9.01(h).

Each Continuing Employee will be credited with his or her years of service with the Company and its Subsidiaries (and any predecessor entities thereof) before the Closing Date under any new parallel employee benefit plan of Parent or its Subsidiaries in which the Continuing Employee become entitled to participate to the same extent as such employee was entitled, before the Closing Date, to credit for such service under the respective Plan (except to the extent such credit would result in the duplication of benefits and except with respect to benefit accrual under a defined benefit plan). In addition, with respect to any such health benefit plan in which the Continuing Employee become entitled to participate during the calendar year that includes the Closing Date, each Continuing Employee shall be given credit for amounts paid by the employee under the respective Plan for purposes of applying deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the parallel plan, program or arrangement of Parent or the Surviving Entity.

(c) Notwithstanding any of the foregoing to the contrary, Parent shall or shall cause the Surviving Entity to provide severance benefits in accordance with Section 7.05(c) of the Disclosure Schedule to any Continuing Employee who is either involuntarily terminated (other than for cause) or asked to relocate the employee’s principal place of employment further than 25 miles, in each case during the twenty-four month period following the Closing Date, in an amount that is at least equal to the severance benefits that would have been paid to such employee pursuant to the terms of the Equity Office Properties Trust Severance Pay Plan disclosed in Section 4.10(a) of the Disclosure Schedule (but with a minimum payment equal to twelve weeks base salary), to be calculated, however, on the basis of the employee’s service at the time of the employee’s termination and the greater of the employee’s compensation at the time of (i) the employee’s termination or (ii) the Company Merger Effective Date.

(d) Prior to the Company Merger Effective Time, the Company Board, or an appropriate committee of non-employee directors thereof, shall adopt a resolution consistent with the interpretive guidance of the SEC so that the disposition by any officer or director of the Company who is a covered person of the Company for purposes of Section 16 of the Exchange Act and the rules and regulations thereunder (“Section 16”) of Company Common Shares or options or other rights to acquire Company Common Shares pursuant to this Agreement and the Company Merger shall be an exempt transaction for purposes of Section 16.

(e) Prior to the Company Merger Effective Time, the Company Board shall take such actions as are necessary to terminate all share or investment-based non-qualified deferred compensation account-based arrangements (collectively, the “Non-Qualified Account

Payment of the Non-Qualified Account Plans shall be in cash to the participants in the Non-Qualified Account Plans in a single lump-sum payment by the Surviving Entity immediately following the Company Merger Effective Time; provided, however, that payment shall be delayed to the date six months following a participant’s separation from service in the event, and to the extent, prior to the Company Merger Effective Time the Company Board determines that such delay is necessary to comply with the requirements of Section 409A of the Code.

(a) Without limiting any additional rights that any director, officer, trustee, employee, agent, or fiduciary may have under any employment or indemnification agreement or under the Company Charter, the Company Bylaws, the Operating Partnership Agreement or this Agreement or, if applicable, similar organizational documents or agreements of any of the Subsidiaries (each of which shall remain in full force and effect following the Mergers and each of which Parent shall cause the Surviving Entity and the Subsidiaries to honor), from and after the Company Merger Effective Time, Parent, the Surviving Entity and the Operating Partnership shall: (i) indemnify and hold harmless each person who is at the date hereof or during the period from the date hereof through the Company Merger Effective Time serving as a trustee, director or officer of the Company or the Subsidiaries (collectively, the “Indemnified Parties”) to the fullest extent authorized or permitted by applicable Law, as now or hereafter in effect, in connection with any Claim and any judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such judgments, fines, penalties or amounts paid in settlement) resulting therefrom; and (ii) promptly pay on behalf of each of the Indemnified Parties, to the fullest extent authorized or permitted by applicable Law, as now or hereafter in effect, any Expenses incurred in defending, serving as a witness with respect to or otherwise participating in any Claim in advance of the final disposition of such Claim, including payment on behalf of or advancement to the Indemnified Party of any Expenses incurred by such Indemnified Party in connection with enforcing any rights with respect to such indemnification and/or advancement, in each case without the requirement of any bond or other security, but subject to Parent’s or the Surviving Entity’s, as applicable, receipt of an undertaking by or on behalf of such Indemnified Party, if required by applicable Law, to repay such Expenses if it is ultimately determined under applicable Laws that such Indemnified Party is not entitled to be indemnified; provided, however, that neither Parent nor the Surviving Entity shall be liable for any settlement effected without Parent’s or the Surviving Entity’s written consent (which consent shall not be unreasonably withheld or delayed) and shall not be obligated to pay the fees and expenses of

- 59-

more than one counsel (selected by a plurality of the applicable Indemnified Parties) for all Indemnified Parties in any jurisdiction with respect to any single Claim except to the extent that two or more of such Indemnified Parties shall have conflicting interests in the outcome of such action. The indemnification and advancement obligations of Parent and the Surviving Entity pursuant to this Section 7.06(a) shall extend to acts or omissions occurring at or before the Company Merger Effective Time and any Claim relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim relating thereto). All rights to indemnification and advancement conferred hereunder shall continue after the date hereof as to a person who has ceased to be a trustee, director or officer of the Company or the Subsidiaries and shall inure to the benefit of such person’s heirs, executors and personal and legal representatives. For purposes of this Section 7.06(a): (x) the term “Claim” means any threatened, asserted, pending or completed Action, whether instituted by any party hereto, any Governmental Authority or any other party, that any Indemnified Party in good faith believes might lead to the institution of any such Action, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism, arising out of or pertaining to matters that relate to such Indemnified Party’s duties or service as a director or officer of the Company or any of the Subsidiaries, at or prior to the Company Merger Effective Time; and (y) term “Expenses” means reasonable attorneys’ fees and all other costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Claim for which indemnification is authorized pursuant to this Section 7.06(a), including any Action relating to a claim for indemnification or advancement brought by an Indemnified Party. Neither Parent nor the Surviving Entity shall settle, compromise or consent to the entry of any judgment in any Claim in respect of which indemnification has been or could be sought by such Indemnified Party hereunder unless (i) such settlement, compromise or judgment includes an unconditional release of such Indemnified Party from all liability arising out of such Claim, (ii) such Indemnified Party otherwise consents thereto, or (iii) Parent or the Surviving Entity acknowledges that such Claim is subject to this Section 7.06.

(b) For a period of six (6) years from the Company Merger Effective Time, the charter and bylaws or other organizational documents of the Surviving Entity and the Subsidiaries shall contain provisions no less favorable with respect to indemnification than are set forth in the Company Charter, Company Bylaws or the applicable organizational documents of the Subsidiaries, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Company Merger Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Company Merger Effective Time, were directors, officers, trustees, employees, agents, or fiduciaries (including fiduciaries under or with respect to any employee benefit plan (within the meaning of Section 3(3) of ERISA)) of the Company or any of its Subsidiaries, unless such modification shall be required by Law and then only to the minimum extent required by Law.

- 60-

(c) Prior to the Closing Date, the Company shall purchase a non-cancelable extended reporting period endorsement under the Company’s existing directors’, trustees’ and officers’ liability insurance coverage for the Company’s directors, trustees and officers in the same form as presently maintained by the Company, with the same or comparably rated insurers as the Company’s current insurer, which shall provide such directors, trustees and officers with coverage for six (6) years following the Closing Date of not less than the existing coverage under, and have other terms not less favorable in the aggregate to, the insured persons than the directors’, trustees’ and officers’ liability insurance coverage presently maintained by the Company; provided that the premium payable for such insurance shall not exceed 300% of the 2007 annual premium to be paid by the Company for such insurance (such 300% amount being the “Maximum Premium”). The Company agrees to consult with Parent in connection with purchasing such coverage. The Company represents that the last annual premium paid by the Company for such insurance prior to the date of this Agreement is set forth in Section 7.06(c) of the Disclosure Schedule. If the Company is unable to obtain the insurance described in the first sentence of this Section 7.06(c) for an amount less than or equal to the Maximum Premium, the Company shall be entitled to obtain as much comparable insurance as possible for an amount equal to the Maximum Premium. Parent shall, and shall cause the Surviving Entity to, maintain such policies in full force and effect, and continue to honor all obligations thereunder.

(d) Notwithstanding anything in this Agreement to the contrary, the obligations under this Section 7.06 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 7.06 applies without the consent of each such affected indemnitee. This Section 7.06 is intended for the irrevocable benefit of, and to grant third party beneficiary rights to, the persons indemnified hereunder and their respective heirs, executors and personal and legal representatives and shall be binding on all successors of the Surviving Entity. Each of such persons and their respective heirs shall be entitled to enforce the provisions of this Section 7.06.

(e) If the Surviving Entity or any of its respective successors or assigns (i) consolidates with or merges with or into any other person and shall not be the continuing or Surviving Entity, partnership or other entity of such consolidation or merger or (ii) liquidates, dissolves or winds-up, or transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the surviving entity assumes the obligations set forth in this Section 7.06.

(f) Parent shall cause the Surviving Entity and the Subsidiaries to perform all of the obligations of the Surviving Entity under this Section 7.06 and the parties acknowledge and agree that Parent guarantees the payment and performance of the Surviving Entity’s obligations pursuant to this Section 7.06.

SECTION 7.07 Further Action; Reasonable Efforts.

(a) Except to the extent otherwise provided in Section 7.01, upon the terms and subject to the conditions of this Agreement, each of the parties hereto shall (i) make promptly its respective filings and thereafter make any other required submissions, under the HSR Act and any other Law with respect to this Agreement and the Mergers, if required, and (ii) use its reasonable efforts to take, or cause to be taken, all appropriate action, and to do, or cause

- 61-

to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the Mergers, and the other transactions contemplated by this Agreement, including using its reasonable efforts to obtain all Permits, consents, approvals, authorizations, qualifications and orders of Governmental Authorities with the Company and the Subsidiaries as are necessary for the consummation of the transactions contemplated by this Agreement and to fulfill the conditions to the Mergers and the other transactions contemplated by this Agreement.

(b) The parties hereto agree to cooperate and assist one another in connection with all actions to be taken pursuant to this Section 7.07, including the preparation and making of the filings referred to therein and, if requested, amending or furnishing additional information thereunder, including, subject to applicable Law and the Confidentiality Agreement, providing copies of all related documents to the non-filing party and their advisors prior to filing, and, to the extent practicable, none of the parties will file any such document or have any communication with any Governmental Authority without prior consultation with the other party. Each party shall keep the other apprised of the content and status of any communications with, and communications from, any Governmental Authority with respect to the transactions contemplated by this Agreement. To the extent practicable and permitted by a Governmental Authority, each party hereto shall permit representatives of the other party to participate in meetings and calls with such Governmental Authority. None of the parties shall consent to any voluntary extension of any statutory deadline or waiting period or to any voluntary delay of the consummation of the transactions contemplated by this Agreement at the behest of any Governmental Authority without the consent of the other party, which consent shall not be unreasonably withheld or delayed.

(c) Each of the parties hereto agrees to cooperate and use its reasonable best efforts to defend through litigation on the merits any Action, including administrative or judicial Action, asserted by any party in order to avoid the entry of, or to have vacated, lifted, reversed, terminated or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) that in whole or in part restricts, delays, prevents or prohibits consummation of the Mergers, including by vigorously pursuing all available avenues of administrative and judicial appeal.

(d) Each of the Buyer Parties, on the one hand, and the Company Parties, on the other hand, shall use their respective commercially reasonable efforts to obtain any third party consents (i) necessary, proper or advisable to consummate the transactions contemplated by this Agreement, (ii) disclosed in Section 7.07(d) of the Disclosure Schedule or (iii) required to prevent a Company Material Adverse Effect from occurring prior to the Company Merger Effective Time. In the event that any Company Party shall fail to obtain any third party consent described above, the Company Parties shall use their commercially reasonable efforts, and shall take such actions as are reasonably requested by Parent, to minimize any adverse effect upon the Company Parties and the Buyer Parties and their respective businesses resulting, or which would reasonably be expected to result, after the Company Merger Effective Time, from the failure to obtain such consent. Notwithstanding anything to the contrary in this Agreement, in connection with obtaining any approval or consent from any Person (other than a Governmental Authority) with respect to any transaction contemplated by this Agreement, (i) unless required by the applicable agreement, without the prior written consent of Parent which shall not be unreasonably withheld or delayed, none of the Company or any of the Subsidiaries shall pay or

- 62-

commit to pay to such Person whose approval or consent is being solicited any cash or other consideration, make any commitment or incur any liability or other obligation due to such Person and (ii) none of the Buyer Parties or their respective affiliates shall be required to pay or commit to pay to such Person whose approval or consent is being solicited any cash or other consideration, make any commitment or incur any liability or other obligation.

SECTION 7.08 Certain Tax Matters.

(a) Parent and the Company shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer or stamp taxes, any transfer, recording, registration and other fees and any similar taxes that become payable in connection with the transactions contemplated by this Agreement (together with any related interests, penalties or additions to Tax, “Transfer Taxes”), and shall cooperate in attempting to minimize the amount of Transfer Taxes. From and after the Company Merger Effective Time, the Surviving Entity shall pay or cause to be paid, without deduction or withholding from any Merger Consideration, including any consideration or amounts payable to holders of the Company Common Shares, Class A Units, Company Preferred Shares, Company Share Options, SARs and/or Company Restricted Shares, all Transfer Taxes.

(b) Parent shall arrange for the preparation and timely filing of all Tax Returns of the Company and the Subsidiaries (including IRS Forms 1099) due after the Closing Date. Parent shall cause all Tax Returns of Company and the Subsidiaries (including withholdings and withholding Tax Returns) to be prepared on a basis consistent with the Tax Returns filed by them prior to the Closing Date, including by the filing of a Form 1120-REIT for the Company for its 2006 and 2007 taxable years. Furthermore, Parent shall cause, to the maximum extent permitted by Law, the Company to properly designate any dividends paid prior to the Closing Date as capital gain dividends for purposes of Code Section 857(b)(3).

SECTION 7.09 Public Announcements. The parties hereto agree that no public release or public announcement concerning the transactions contemplated by this Agreement (including the Mergers) shall be issued by a party without the prior consent of the other parties (which consent shall not be unreasonably withheld), except as such release or announcement may be required by Law or the rules or regulations of any securities exchange. The parties have agreed upon the form of a joint press release announcing the Mergers and the execution of this Agreement.

SECTION 7.10 Cooperation with Financing.

(a) Parent shall use its reasonable best efforts to arrange the Financing on the terms and conditions described in the Commitment Letters, including using reasonable best efforts to (i) negotiate definitive agreements with respect thereto on terms and conditions contained therein and (ii) to satisfy all conditions applicable to the Buyer Parties in such definitive agreements that are within their control. In the event any portion of the Financing becomes unavailable on the terms and conditions contemplated in the Commitment Letters, Parent shall use its reasonable best efforts to arrange to obtain any such portion from alternative sources on comparable or more favorable terms to Parent (as determined in the reasonable

- 63-

judgment of Parent) as promptly as practicable following the occurrence of such event. Parent shall give the Company prompt written notice of any material breach by any party of the Commitment Letters or any termination of the Commitment Letters. Parent shall keep the Company informed on a reasonably current basis in reasonable detail of the status of its efforts to arrange the Financing and shall not permit any material amendment or modification to be made to, or any waiver of any material provision or remedy under, the Commitment Letters without first consulting with the Company or, if such amendment would or would be reasonably expected to materially and adversely affect or delay in any material respect Parent’s ability to consummate the transactions contemplated by this Agreement, without first obtaining the Company’s prior written consent (not to be unreasonably withheld or delayed). For the avoidance of doubt, if the Financing (or any alternative financing) has not been obtained, the Buyer Parties shall continue to be obligated to consummate the Mergers on the terms contemplated by this Agreement and subject only to the satisfaction or waiver of the conditions set forth in Sections 8.01 and 8.02 of this Agreement and to Parent’s rights under Section 9.01, regardless of whether the Buyer Parties have complied with all of their other obligations under this Agreement (including their obligations under this Section 7.10).

(b) The Company agrees to provide, and shall cause the Subsidiaries and its and their Representatives to provide, all reasonable cooperation in connection with the arrangement of the Financing as may be reasonably requested by Parent (provided that such requested cooperation does not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries), including (i) participation in meetings, drafting sessions and due diligence sessions, (ii) furnishing Parent and its financing sources with financial and other pertinent information regarding the Company and the Subsidiaries as may be reasonably requested by Parent, (iii) assisting Parent and its financing sources in the preparation of (A) any offering document for any Financing to be raised to complete the Mergers and (B) materials for rating agency presentations, (iv) reasonably cooperating with the marketing efforts of Parent and its financing sources for any Financing to be raised by Parent to complete the Mergers, (v) forming new direct or indirect Subsidiaries, (vi) providing and executing documents as may be reasonably requested by Parent and (vii) without limiting the obligations of the Company and the Subsidiaries under Sections 3.07 and 3.08, cooperating in connection with the repayment or defeasance of any Indebtedness of the Company or any of the Subsidiaries as of the Partnership Mergers Effective Time, including delivering such payoff, defeasance or similar notices under any existing mortgage or mezzanine loans of the Company or any Subsidiary as reasonably requested by Parent; provided that none of the Company or any Subsidiary shall be required to pay any commitment or other similar fee or make any other payment other than reasonable out-of-pocket costs or incur any other liability in connection with the Financing or any of the foregoing prior to the Company Merger Effective Time. Parent shall, promptly upon request by the Company, reimburse the Company for all reasonable out-of-pocket costs incurred by the Company, its Subsidiaries and their Representatives in connection with such cooperation. The Buyer Parties shall, on a joint and several basis, indemnify and hold harmless the Company, the Subsidiaries and their respective Representatives from and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties suffered or incurred by them in connection with the arrangement of the Financing (including any action taken in accordance with this Section 7.10(b)) and any information utilized in connection therewith (other than historical information relating to the Company or the Subsidiaries). Notwithstanding anything to the contrary, the condition set forth in Section 8.02(b), as it applies to the Company’s

- 64-

obligations under this Section 7.10(b), shall be deemed satisfied unless the Financing (or any alternative financing) has not been obtained primarily as a result of the Company’s or the Subsidiaries’ willful and material breach of its obligations under this Section 7.10(b).

(c) All non-public or otherwise confidential information regarding the Company obtained by Parent or its Representatives pursuant to paragraph (b) above shall be kept confidential in accordance with the Confidentiality Agreement.

SECTION 7.11 Resignations. The Company shall use its reasonable best efforts to obtain and deliver to Parent at the Closing evidence reasonably satisfactory to Parent of the resignation effective as of the Partnership Merger Effective Time, of those directors of the Company or any Subsidiary designated by Parent to the Company in writing at least five calendar days prior to the Closing.

SECTION 7.12 Takeover Statutes. If any takeover statute is or becomes applicable to this Agreement, the Mergers or the other transactions contemplated by this Agreement, each of the parties and their respective boards of directors or boards of trustees (or managing members or general partners, as applicable) shall use their reasonable efforts to (a) take all necessary action so that the transactions contemplated hereby may be consummated as promptly as practicable upon the terms and subject to the conditions set forth in this Agreement and (b) otherwise act to eliminate or minimize the effects of such takeover statute.

SECTION 7.13 Delisting and Deregistering of Securities. Parent and the Company shall use their commercially reasonable efforts to cause the Company Common Shares to be de-listed from the NYSE and de-registered under the Exchange Act promptly following the Company Merger Effective Time.

SECTION 7.14 Tax Matters. During the period from the date of this Agreement to the Company Merger Effective Time, the Company and its Subsidiaries shall:

(a) continue to operate in such a manner as to permit the Company to continue to qualify as a REIT throughout the period from the date hereof to the Company Merger Effective Time;

(b) prepare and timely file all material Tax Returns required to be filed by them on or before the Closing Date (“Post-Signing Returns”) in a manner consistent with past practice, except as otherwise required by applicable Laws;

(a) The Company Parties shall notify Parent promptly of (i) any written communication and, to the knowledge of the Company, any other communication from any Person alleging that the consent of such Person (or another Person) is or may be required in connection with the transactions contemplated by this Agreement (and the response thereto from the Company, any of the Subsidiaries or their Representatives), (ii) any communication from any Governmental Authority in connection with the transactions contemplated by this Agreement (and the response thereto from the Company, any of the Subsidiaries or their Representatives), (iii) any material Actions threatened or commenced against or otherwise affecting the Company or any of the Subsidiaries that are related to the transactions contemplated by this Agreement or (iv) any effect, event, development or change between the date of this Agreement and the Company Merger Effective Time which, to the knowledge of the Company, causes or is reasonably likely to cause the conditions set forth in Section 8.02(a) or 8.02(b) not to be satisfied.

(b) The Buyer Parties shall notify the Company promptly of (i) any written communication and, to the knowledge of Parent, any other communication from any Person alleging that the consent of such Person (or another Person) is or may be required in connection with the transactions contemplated by this Agreement (and the response thereto from Parent, any of its subsidiaries or their Representatives), (ii) any communication from any Governmental Authority in connection with the transactions contemplated by this Agreement (and the response thereto from Parent, any of its subsidiaries or their Representatives), (iii) any material Actions threatened or commenced against or otherwise affecting Parent or any of its subsidiaries that are related to the transactions contemplated by this Agreement or (iv) any effect, event, development or change between the date of this Agreement and the Company Merger Effective Time, which to the knowledge of Parent, causes or is reasonably likely to cause the conditions set forth in Section 8.03(a) or 8.03(b) not to be satisfied.

(v) during the three (3) Business Day period following Parent’s receipt of such notice, (i) the Company shall have offered to negotiate with (and, if accepted, negotiated in good faith with), and shall have caused its respective financial and legal advisors to offer to negotiate with (and, if accepted, negotiate in good faith with), Parent in making adjustments to the terms and conditions of this Agreement as would enable the Company to proceed with the Mergers and the other transactions contemplated by this Agreement, and (ii) the Company Board shall have determined in good faith, after the end of such three Business Day period, after considering the results of any such negotiations and the revised proposals made by Parent, if any, that the Superior Proposal giving rise to such notice continues to be a Superior Proposal; and

(vi) the Company pays to Parent the Company Termination Fee in accordance with Section 9.03(b)(ii) simultaneously with such termination (any purported termination pursuant to this Section 9.01(h) shall be void and of no force or effect unless the Company shall have made such payment).

SECTION 9.02 Effect of Termination. In the event of the termination of this Agreement pursuant to Section 9.01, this Agreement shall forthwith become void, and there shall be no liability under this Agreement on the part of any party hereto (or any Representatives thereof) except that the indemnification and reimbursement obligations of the Buyer Parties contained in Sections 2.06, 3.07 and 7.10(b), the Guarantee referred to in Section 5.07(c) and the provisions of Section 7.03(b), Section 7.10(c), this Section 9.02, Section 9.03 and Article X shall survive any such termination; provided, however, that nothing herein shall relieve any party hereto from liability for any willful breach of any of its representations or warranties, or any breach of its covenants or agreements set forth in this Agreement prior to such termination.

SECTION 9.03 Fees and Expenses.

(a) Except as otherwise set forth in this Section 9.03, all expenses (including fees and expenses payable to Representatives and hedging counterparties) incurred by any party to this Agreement or its Affiliates on its behalf in connection with this Agreement or the transactions contemplated by this Agreement (“Expenses”) shall be paid by the party incurring such expenses, whether or not the Mergers are consummated.

(b) The Company agrees that if this Agreement shall be terminated:

(i) by Parent or the Company pursuant to Section 9.01(b) or Section 9.01(f) or by Parent pursuant to Section 9.01(d) (however, only in the event of a termination pursuant to Section 9.01(d) that relates to a breach by the Company Parties of their obligations under Section 7.02 or Section 7.04) and (A) an Acquisition Proposal shall have been made to the Company Parties or publicly announced prior to such Termination Date (and with respect to termination pursuant to Section 9.01(b), such Acquisition Proposal was not withdrawn prior to the Termination Date), and (B) concurrently with such termination or within twelve (12) months following the Termination Date, the Company enters into a Contract with respect to an Acquisition Proposal, or an Acquisition Proposal is consummated (in each case whether or not such Acquisition Proposal was the same Acquisition Proposal referred to in the foregoing

-71-

clause (A)), then the Company shall pay to Parent, if and when such Contract is entered into or consummation of such Acquisition Proposal occurs, as applicable, the Company Termination Fee (and for purposes of this Section 9.03(b)(i), “50%” shall be substituted for “20%” in the definition of Acquisition Proposal); or

(ii) by Parent pursuant to Section 9.01(g), or the Company pursuant to Section 9.01(h), then the Company shall pay to Parent the Company Termination Fee on the Termination Date, and with respect to a termination pursuant to Section 9.01(h), such payment shall be made before or concurrently with such termination and shall be a condition to the effectiveness of such termination.

(c) Except as set forth in Section 9.03(b)(ii) for termination by the Company pursuant to Section 9.01(h), the Company Termination Fee shall be paid by the Company as directed by Parent in writing in immediately available funds within three (3) Business Days after the date of the event giving rise to the obligation to make such payment.

(d) For purposes of this Agreement, “Company Termination Fee” means an amount equal to $200,000,000.

(e) Subject to Section 10.06, if this Agreement is terminated by the Company pursuant to Section 9.01(e), Parent shall pay to the Company within three (3) Business Days after the date of termination, the reasonable Expenses of the Company Parties not to exceed $7,500,000 (the “Company Expenses”). If this Agreement is terminated by Parent pursuant to Section 9.01(d), the Company shall pay to Parent within three (3) Business Days after the date of termination, the reasonable Expenses of the Buyer Parties not to exceed $7,500,000 (the “Parent Expenses”), and to the extent any Parent Expenses are paid by the Company to Parent, such amount shall be deducted from any Company Termination Fee that may thereafter be payable by the Company pursuant to Section 9.03(b). Subject to Section 10.06, the payment of Company Expenses or Parent Expenses set forth in this Section 9.03 is not an exclusive remedy, but is in addition to any other rights or remedies available to the parties hereto (whether at law or in equity), and in no respect is intended by the parties hereto to constitute liquidated damages, or be viewed as an indicator of the damages payable, or in any other respect limit or restrict damages available in case of any breach of this Agreement.

(f) Each of the parties hereto acknowledges that the agreements contained in this Section 9.03 are an integral part of the transactions contemplated by this Agreement. In the event that the Company shall fail to pay the Company Termination Fee or Parent Expenses when due or Parent shall fail to pay the Company Expenses when due, the Company or Parent, as the case may be, shall reimburse the other party for all reasonable costs and expenses actually incurred or accrued by such other party (including reasonable fees and expenses of counsel) in connection with the collection under and enforcement of this Section 9.03.

SECTION 9.04 Escrow.

(a) To the extent that the Company Parties recover money damages pursuant to and subject to Section 10.06 and the Guarantee (the “Damages Amount”), Parent shall instruct the escrow agent to pay to the Operating Partnership from the Damages Amount deposited into

-72-

escrow in accordance with the next sentence, an amount equal to the lesser of (i) the Damages Amount and (ii) the sum of (1) the maximum amount that can be paid to the Operating Partnership without causing the Company to fail to meet the requirements of Sections 856(c)(2) and 856(c)(3) of the Code determined as if the payment of such amount did not constitute income described in Sections 856(c)(2)(A)-(H) or 856(c)(3)(A)-(I) of the Code (“Qualifying Income”), as determined by the Company’s independent certified public accountants, plus (2) in the event the Company receives either (A) a letter from the Company’s counsel indicating that the Company has received a ruling from the IRS described in Section 9.04(b) or (B) an opinion from the Company’s outside counsel as described in Section 9.04(b), an amount equal to the Damages Amount less the amount payable under clause (1) above. To secure Parent’s obligation to pay these amounts, Parent shall deposit into escrow an amount in cash equal to the Damages Amount with an escrow agent selected by Parent and on such terms (subject to Section 9.04(b)) as shall be mutually agreed upon by the Operating Partnership, Parent and the escrow agent. Subject to the terms of Section 10.06 and the Guarantee, the payment or deposit into escrow of the Damages Amount pursuant to this Section 9.04 shall be made at the time Parent is obligated to pay the Operating Partnership such amount pursuant to Section 10.06 and the Guarantee by wire transfer or bank check.

(b) The escrow agreement shall provide that the Damages Amount in escrow or any portion thereof shall not be released to the Operating Partnership unless the escrow agent receives any one or combination of the following: (i) a letter from the Company’s independent certified public accountants indicating the maximum amount that can be paid by the escrow agent to the Operating Partnership without causing the Company to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if the payment of such amount did not constitute Qualifying Income or a subsequent letter from the Company’s accountants revising that amount, in which case the escrow agent shall release such amount to the Company, or (ii) a letter from the Company’s counsel indicating that the Company received a ruling from the IRS holding that the Damages Amount would either constitute Qualifying Income or would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code (or alternatively, the Company’s outside counsel has rendered a legal opinion to the effect that the receipt by the Operating Partnership of the Damages Amount would constitute Qualifying Income, would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code or would not otherwise disqualify Company as a REIT), in which case the escrow agent shall release the remainder of the Damages Amount to the Operating Partnership. Parent agrees to amend this Section 9.04 at the reasonable request of the Company in order to (x) maximize the portion of the Damages Amount that may be distributed from the escrow account to the Operating Partnership hereunder without causing the Company to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, (y) improve the Company’s chances of securing a favorable ruling described in this Section 9.04(b) or (z) assist the Company in obtaining a favorable legal opinion from its outside counsel as described in this Section 9.04(b). The escrow agreement shall also provide that any portion of the Damages Amount held in escrow for ten years shall be released by the escrow agent to Parent. Any costs and expenses of the escrow agent shall be borne solely by the Company.

SECTION 9.05 Waiver. At any time prior to the Company Merger Effective Time, the Company, on the one hand, and Parent, on the other hand, may (a) extend the time for the performance of any obligation or other act of the other party, (b) waive any inaccuracy in the

-73-

representations and warranties of the other party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any agreement of the other party or any condition to its own obligations contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the Company (on behalf of the Company Parties) or Parent (on behalf of the Buyer Parties), as applicable. The failure of any party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

ARTICLE X

SECTION 10.03 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy or the application of this Agreement to any person or circumstance is invalid or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. To such end, the provisions of this Agreement are agreed to be severable. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the fullest extent possible.

SECTION 10.04 Amendment.

This Agreement may be amended by the parties hereto by action taken by their respective board of directors (or similar governing body or entity) at any time prior to the Company Merger Effective Time; provided, however, that, after approval of the Company Merger by the shareholders of the Company, no amendment may be made without further shareholder approval which, by Law or in accordance with the rules of the NYSE, requires further approval by such shareholders. This Agreement may not be amended except by an instrument in writing signed by the parties hereto.

SECTION 10.05 Entire Agreement; Assignment.

This Agreement, together with the Confidentiality Agreement and the Disclosure Schedule, constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), except any of the Buyer Parties may assign this Agreement to any direct or indirect wholly-owned subsidiary of Parent, provided, however, that no such assignment shall relieve the assigning party of its obligations hereunder if the assignee does not perform its obligations.

SECTION 10.06 Remedies. Except as otherwise provided in Section 10.07 or elsewhere in this Agreement, any and all remedies expressly conferred upon a party to this Agreement shall be cumulative with, and not exclusive of, any other remedy contained in this Agreement, at law or in equity and the exercise by a party to this Agreement of any one remedy shall not preclude the exercise by it of any other remedy. Without limiting the right to receive any payment it may be entitled to receive under Sections 2.06 and 7.10(b), each of the Company Parties agrees that to the extent it has incurred losses or damages (including any amounts paid by Parent pursuant to Section 9.03(e)) in connection with this Agreement the maximum aggregate

-75-

liability of the Buyer Parties and Guarantor for such losses or damages shall be limited to an amount equal to the amount of the Guarantee, and in no event shall the Company Parties seek to recover any money damages in excess of such amount from the Buyer Parties or Guarantor or their respective Representatives and affiliates in connection therewith.

SECTION 10.07 Specific Performance. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement were not performed by any Company Party in accordance with the terms hereof and that, prior to the termination of this Agreement pursuant to Section 9.01, the Buyer Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by the Company Parties and to enforce specifically the terms and provisions of this Agreement in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity. The parties acknowledge that none of the Company Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the terms and provisions of this Agreement and that the Company Parties’ sole and exclusive remedy with respect to any such breach shall be the remedy set forth in Section 10.06 and the Guarantee; provided, however, the Company Parties shall be entitled to seek specific performance to prevent any breach by the Buyer Parties of Sections 7.03(b) and 7.10(c).

SECTION 10.08 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than the provisions of Section 7.06 (which are intended to be for the benefit of the persons covered thereby and the persons entitled to payment thereunder and may be enforced by such persons).

SECTION 10.09 Governing Law; Forum. The Company Merger shall be governed by, and construed in accordance with, the laws of the State of Maryland applicable to contracts executed in and to be performed in that State without regard to its rules of conflict of laws. Except as provided in the immediately proceeding sentence, this Agreement and all disputes, claims or controversies arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the transactions contemplated hereby shall be governed by and construed in accordance with the laws of the State of Delaware without regard to its rules of conflict of laws.

Each of the parties hereto hereby irrevocably and unconditionally consents to submit to the sole and exclusive jurisdiction of the Court of Chancery of the State of Delaware (the “Delaware Courts”) for any litigation arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the transactions contemplated hereby (and agrees not to commence any litigation relating thereto except in such courts), waives any objection to the laying of venue of any such litigation in the Delaware Courts and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in any inconvenient forum. Each of the parties hereto agrees, (a) to the extent such party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such party’s agent for acceptance of legal process, and (b) that service of process may also be made on such party by prepaid certified mail to the address for notice in Section 10.02 with a proof of mailing receipt validated by the United States Postal

-76-

Service constituting evidence of valid service. Service made pursuant to (a) or (b) above shall have the same legal force and effect as if served upon such party personally within the State of Delaware.

SECTION 10.10 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

SECTION 10.11 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in two or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

SECTION 10.12 Waiver. Except as provided in this Agreement, no action taken pursuant to this Agreement, including any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained in this Agreement. The waiver by any party hereto of a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder.

SECTION 10.13 Waiver of Jury Trial. Each of the parties hereto hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the transactions contemplated by this Agreement. Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, to it that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other hereto have been induced to enter into this Agreement and the transactions contemplated by this Agreement, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.13.
