ARTICLE II

EFFECT OF THE MERGERS ON CAPITAL STOCK, COMMON

SHARES, WARRANTS, COMPANY OPTIONS AND PARTNERSHIP UNITS

Section 2.1. Effect of REIT Merger on Capital Stock, Common Shares and Warrants. At the REIT Effective Time, by virtue of the REIT Merger and without any action on the part of any of the Purchaser Parties, the Company or the holder of any Equity Interests (as defined in Section 9.1) of Merger Sub or common shares of beneficial interest, par value $0.01 per share, of the Company (the “Common Shares”):

(a) Conversion of Common Shares. Each Common Share (other than Excluded Shares (as defined in Section 2.1(b)) issued and outstanding immediately prior to the REIT Effective Time (including all Common Shares issued after the date of this Agreement and prior to the REIT Effective Time in exchange for LP Units in accordance with the terms of such LP Units) (such Common Shares are each hereinafter referred to as a “Share” and collectively as the “Shares”), shall be converted automatically into the right to receive $7.25 in cash, without interest (the “REIT Merger Consideration”). At the REIT Effective Time, all Shares shall be cancelled automatically and shall cease to exist, and the holders of Certificates (as defined in Section 2.2(c)(i)) which formerly represented Shares shall cease to have any rights with respect to the Shares, other than the right to receive the REIT Merger Consideration per share (without any interest being payable thereon) upon surrender of the Certificates in accordance with Section 2.2.

(b) Cancellation of Certain Common Shares and Purchaser Party-Owned Common Shares. Each Common Share issued and outstanding and owned by the Company, the Operating Partnership, or any of their respective wholly-owned Subsidiaries, or by the Purchaser Parties, or any of their wholly-owned Subsidiaries, immediately prior to the REIT Effective Time (collectively, the “Excluded Shares”) shall be cancelled automatically and shall cease to exist, without payment of any consideration being made in respect thereof.

(c) Conversion of Merger Sub Equity Interests. The Equity Interests of Merger Sub issued and outstanding immediately prior to the REIT Effective Time shall be converted automatically into and become fully paid and non-assessable common shares of beneficial interest, par value $0.01 per share, of the Surviving Entity (the “Surviving Entity Shares”). The number of Surviving Entity Shares shall be equal to 1.0% of the number of Common Shares outstanding at and immediately before the REIT Effective Time and shall constitute 100% of the total common equity of the Surviving Entity at and immediately after the REIT Effective Time.

(d) Series B Shares. The REIT Merger shall have no effect on the Company’s outstanding Series B Cumulative Redeemable Preferred Shares of Beneficial Interest, par value $0.01 per share (the “Series B Shares”), and, at and after the REIT Effective Time, the Series B Shares shall be the outstanding Series B Shares of the Surviving Entity.

(e) Warrants. The Company shall take such actions as are necessary to assure that, as of the REIT Effective Time, each Warrant, by virtue of the REIT Merger and without any further action on the part of the Purchaser Parties, the Company or the holder of such Warrant, shall be (i) converted automatically into the right upon exercise to acquire and receive, in lieu of the Common Shares otherwise acquirable and receivable upon the exercise of such Warrant immediately prior to the REIT Effective Time, an aggregate amount in cash, without interest, equal to the product of (x) the per share REIT Merger Consideration and (y) the maximum number of Common Shares subject to such Warrant (after giving effect to the adjustment set forth in clause (ii) of this sentence) (with respect to such Warrant, this product is referred to as the “Warrant REIT Merger Consideration”) and (ii) modified automatically to provide that (x) the Exercise Price (as defined in such Warrant) is adjusted to $7.25 per Common Share (the “Adjusted Exercise Price”) subject to such Warrant and (y) the maximum number of Common Shares subject to such Warrant is adjusted to 517,241 Common Shares in the case of the Series A-2 Share Purchase Warrant, 344,878 Common Shares in the case of the Series B Share Purchase Warrant and 431,034 Common Shares in the case of the Series C Share Purchase Warrant. From and after the REIT Effective Time, the Warrants, as so converted and modified in accordance with this Section 2.1(e), shall be exercisable solely for the per share Warrant REIT Merger Consideration (in exchange for the payment by the holder(s) of the Warrants to the Company of the Adjusted Exercise Price), and shall not be exercisable for the purchase of Common Shares.

(f) Series A Shares. Prior to the Closing Date, the Company shall take such actions as are necessary to cause the Operating Partnership to distribute the Series A Shares to the Company in exchange for the Series A Preferred Units. Upon any such distribution of the Series A Shares to the Company, the Series A Shares shall be automatically cancelled and reclassified as authorized but unissued preferred shares of the Company in accordance with Maryland law and the Company Declaration of Trust. In the alternative, the Company may take such actions as are necessary and which are reasonably acceptable to the Purchaser Parties to effectuate the intent of the foregoing.

(g) Dissenters’ Rights. No dissenters’, appraisal or similar rights shall be available with respect to the REIT Merger.

Section 2.2. Surrender of Certificates.

(a) Paying Agent. Prior to the OP Effective Time, the Purchaser Parties shall (i) select a bank or trust company to act as the paying agent in the OP Merger and the REIT Merger (the “Paying Agent”), and (ii) enter into an agreement with the Paying Agent containing customary terms and conditions. The selection of the Paying Agent shall be subject to the prior approval of the Company, which approval shall not be unreasonably withheld.

(b) Payment Fund. On the Closing Date and prior to the OP Effective Time, Parent, Merger Sub and OP Merger Sub (or any of them) shall deposit with the Paying Agent such amount of immediately available funds as is necessary for the payment of, in each case for the benefit of the holders of Eligible LP Units and Shares for exchange in accordance with this Article II and for the benefit of the holders of Company Options for payment in accordance with Section 2.3(a), the aggregate OP Merger Consideration, REIT Merger Consideration and Option Merger Consideration. Such funds provided to the Paying Agent are referred to herein as the “Payment Fund.” The Paying Agent shall make payments of the OP Merger Consideration, REIT Merger Consideration and Option Merger Consideration in accordance with this Agreement, the OP Merger Certificate and the Articles of Merger. The Payment Fund shall not be used for any other purpose. Any and all interest earned on the Payment Fund shall be paid to the Surviving Entity.

(i) Letter of Transmittal. Promptly after the REIT Effective Time, but in no event more than five (5) Business Days thereafter, the Surviving Entity shall cause the Paying Agent to mail to each holder of record of a certificate or certificates which, immediately prior to the REIT Effective Time, represented outstanding Shares (each, a “Certificate”), at the REIT Effective Time (A) a letter of transmittal specifying that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Paying Agent and which letter shall be in such form and have such other provisions (including provisions for the delivery of certificates of non-foreign status) as the Purchaser Parties shall reasonably specify and to which the Company shall reasonably approve prior to the Effective Time and (B) instructions for surrendering the Certificates.

(ii) Surrender of Certificates. Upon surrender of a Certificate for cancellation to the Paying Agent or such agent or agents as the Purchaser Parties may designate, together with a duly executed letter of transmittal and any other documents reasonably required by the Paying Agent and reasonably approved by the Company prior to the Effective Time (including, if applicable, duly executed certificates of non-foreign status), the holder of such Certificate shall be entitled to receive in exchange therefor the REIT Merger Consideration, payable in respect of such Certificate less any required withholding of Taxes in accordance with Section 2.2(e). Any Certificates so surrendered shall be cancelled immediately. No interest shall accrue or be paid on any amount payable upon surrender of the Certificates.

(iii) Unregistered Transferees. If any REIT Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate is registered, then the REIT Merger Consideration may be paid to such a transferee so long as (A) the surrendered Certificate is accompanied by all documents reasonably required to evidence and effect such transfer and (B) the Person requesting such payment (1) pays any applicable transfer taxes or (2) establishes to the reasonable satisfaction of the Purchaser Parties and the Paying Agent that such taxes have already been paid or are not applicable.

(iv) No Other Rights. Until surrendered in accordance with this Section 2.2(c), each Certificate shall be deemed, except as provided in this Agreement or by applicable Law, from and after the REIT Effective Time, to represent for all purposes solely the right to receive the REIT Merger Consideration in accordance with the terms hereof. Payment of the REIT Merger Consideration upon the surrender of any Certificate shall be deemed to have been paid in full satisfaction of all rights pertaining to that Certificate and the Shares formerly represented by it. The Option Merger Consideration paid with respect to Company Options in accordance with this Article II and Section 2.3(a) shall be deemed to have been paid in full satisfaction of all rights pertaining to the cancelled Company Options and on and after the REIT Effective Time the holder of a Company Option shall have no further rights to exercise any Company Option.

(d) No Further Transfers. Upon and after the REIT Effective Time, the share transfer books of the Company shall be closed and there shall be no further registration of transfers of the Common Shares that were outstanding immediately prior to the REIT Effective Time. If, after the REIT Effective Time, Certificates are presented to the Surviving Entity for any reason, they shall be cancelled and exchanged for cash as provided in this Article II.

(e) Required Withholding. The Purchaser Parties and the Paying Agent shall be entitled to deduct and withhold from any REIT Merger Consideration or Option Merger Consideration, as the case may be, payable under this Agreement such amounts as may be required to be deducted or withheld therefrom under (i) the Code or (ii) any applicable state, local or foreign Tax Laws. To the extent that amounts are so deducted and withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

(f) No Liability. Neither the Purchaser Parties nor the Paying Agent shall be liable to any holder of Certificates or Company Options for any amount properly paid from the Payment Fund or delivered to a public official under any applicable abandoned property, escheat or similar Law.

(g) Investment of Payment Fund. The Paying Agent shall invest the Payment Fund as directed by the Purchaser Parties. Any interest and other income resulting from such investment shall be deemed property of, and shall be paid promptly to, the Surviving Entity. Any losses resulting from such investment shall not in any way diminish the obligations of Parent, Merger Sub and OP Merger Sub hereunder to pay the full amount of the aggregate OP Merger Consideration, REIT Merger Consideration and Option Merger Consideration.

(h) Termination of Payment Fund. Any portion of the Payment Fund that remains unclaimed by the holders of Certificates or Company Options nine (9) months after the REIT Effective Time shall be delivered by the Paying Agent to the Surviving Entity upon demand, which shall hold such amounts for the holders of Certificates or Company Options (to the extent the Option Merger Consideration is payable in respect of such Company Options). Any holder of Certificates or Company Options who has not complied with this Article II shall

look thereafter only to the Surviving Entity for payment of the applicable REIT Merger Consideration or Option Merger Consideration, as the case may be, without interest on such REIT Merger Consideration or Option Merger Consideration and only as general creditors thereof. If any Certificates or Company Options shall not have been surrendered immediately prior to the date on which any REIT Merger Consideration or Option Merger Consideration, as the case may be, would otherwise become subject to any abandoned property, escheat or similar Law, the REIT Merger Consideration or Option Merger Consideration payable in respect of such Certificates or Company Options shall, to the extent permitted by applicable Law and at the option of the Surviving Entity, on the Business Day immediately prior to such date become the property of Surviving Entity, free and clear of any claim or interest of any Person previously entitled thereto.

(i) Lost, Stolen or Destroyed Certificates. If any Certificate is 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 the Surviving Entity, the posting by such Person of a bond in such reasonable and customary form and amount as the Surviving Entity may direct as indemnity against any claim that may be made against the Surviving Entity with respect to the alleged loss, theft or destruction of such Certificate, the Paying Agent shall pay the REIT Merger Consideration to such Person in exchange for such lost, stolen or destroyed Certificate.

Section 2.3. Company Options.

(a) The Company shall take such actions as are necessary to assure that, as of the REIT Effective Time, each option to acquire Common Shares (each, a “Company Option”) issued under the Company Share Incentive Plan and outstanding immediately prior to the REIT Effective Time, whether or not then exercisable or vested, by virtue of the REIT Merger and without any further action on the part of the Purchaser Parties, the Company or the holder of that Company Option, shall be cancelled and converted into the right to receive an amount in cash, without interest, equal to the product of (x) the excess of the REIT Merger Consideration per share over the exercise or purchase price per share of such Company Option, and (y) the number of Common Shares subject thereto (the aggregate of such amounts hereinafter referred to as the “Option Merger Consideration”). The payment of the Option Merger Consideration to the holder of a Company Option shall be reduced by any income or employment Tax withholding required under (i) the Code or (ii) any applicable state, local or foreign Tax Laws. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes under this Agreement as having been paid to the holder of that Company Option. At the REIT Effective Time, all Company Options shall be cancelled and the Company Share Incentive Plan shall terminate. The Company shall take such actions as are necessary to ensure that the Company Share Incentive Plan shall terminate as of the REIT Effective Time. All administrative and other rights and authorities granted under the Company Share Incentive Plan to the Company, the Company Board or any committee or designee thereof, shall, following the REIT Effective Time, reside with the Surviving Entity. Notwithstanding the foregoing, if the exercise price per share or unit provided for in any Company Option exceeds the REIT Merger Consideration per share, no cash shall be paid with regard to such Company Option to the holder of such Company Option. Prior to the REIT Effective Time, the Company and the Purchaser Parties shall establish a procedure to effect the surrender of Company Options contemplated by this Section 2.3(a) and payment of the Option Merger Consideration by the Paying Agent out of the Payment Fund.

(b) The Company shall take such actions as are necessary to cause dispositions of Company equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual that is an officer or trustee of the Company to be exempt from Section 16(b) of the Exchange Act under Rule 16b-3 under the Exchange Act in accordance with the Rule 16b-3 No-Action Letter.

Section 2.4. Restricted Shares. The Company shall take such actions as are necessary so that as of the REIT Effective Time, each restricted Common Share granted by the Company Board which as of the Closing Date is issued and outstanding but not vested, shall fully vest. At the REIT Effective Time, each issued and outstanding restricted Common Share shall be converted into the right to receive the REIT Merger Consideration as provided in Section 2.1(a).

Section 2.5. Adjustments to Merger Consideration. If during the period between the date of this Agreement and the Effective Time, any change in the outstanding Shares shall occur, including, but not limited to, by reason of any reclassification, recapitalization, share dividend, share split, reverse split or combination, exchange or readjustment of Shares, or any share dividend thereon with a record date during such period (but not as a result of (x) the exercise of (i) outstanding Company Options or (ii) all or any portion of the Warrants, (y) the exchange of any outstanding LP Units for Common Shares or (z) the conversion of Series A Shares to Common Shares pursuant to Section 2.1(f)), the amount per share to be paid to holders of Shares in the REIT Merger Consideration and the holders of Company Options in the Option Merger Consideration, as applicable, shall be appropriately adjusted.

Section 2.6. Effect of OP Merger on the Partnership Units. At the OP Effective Time, by virtue of the OP Merger and without any action on the part of any of the Purchaser Parties, the Operating Partnership or the holders of any of the outstanding Equity Interests of OP Merger Sub or the Partnership Units:

(a) Conversion of LP Units. Each LP Unit (other than Excluded LP Units (as defined in Section 2.6(b) issued and outstanding immediately prior to the OP Effective Time (such LP Units are each hereinafter referred to as an “Eligible LP Unit” and collectively, as the “Eligible LP Units”), shall be converted automatically into the right to receive $7.25 in cash, without interest (the “OP Merger Consideration”). At the OP Effective Time, all Eligible LP Units shall be cancelled automatically and shall cease to exist, and the holders of certificates which immediately prior to the OP Effective Time represented Eligible LP Units (the “LP Unit Certificates”) shall cease to have any rights with respect to the Eligible LP Units, other than the right to receive the OP Merger Consideration per Eligible LP Unit (without any interest being payable thereon) upon surrender of the LP Unit Certificates in accordance with Section 2.7.

(b) Cancellation of Certain LP Units and Purchaser Party-Owned Partnership Units. Each LP Unit issued and outstanding and owned by the Company, the Operating Partnership, or any of their respective wholly-owned Subsidiaries, or by the Purchaser Parties, or any of their wholly-owned Subsidiaries, immediately prior to the OP Effective Time (collectively, the “Excluded LP Units”) shall be cancelled automatically and shall cease to exist, without payment of any consideration being made in respect thereof.

(c) Cancellation of GP Units. Each GP Unit issued and outstanding immediately prior to the OP Effective Time shall be converted automatically into the right of the Company, as the sole holder of GP Units, to receive, in the aggregate, cash and common units of general partnership interest in the Surviving Partnership having a combined aggregate value equal to the product of $7.25 multiplied by the number of GP Units cancelled pursuant to this Section 2.6(c) (such common units of general partnership interest received upon surrender of GP Units cancelled pursuant to this Section 2.6(c), the “Surviving Partnership GP Units”). The number of Surviving Partnership GP Units shall be equal to 1.0% of the number of GP Units outstanding at and immediately before the OP Effective Time. After the OP Effective Time and pursuant to the Surviving Partnership Agreement, the Surviving Partnership GP Units shall not be convertible into Company Shares of the Company or the Surviving Entity.

(d) Conversion of Equity Interests of OP Merger Sub. The Equity Interests of OP Merger Sub issued and outstanding immediately prior to the OP Effective Time shall be converted automatically into units of limited partner interest in the Surviving Partnership (the “Surviving Partnership LP Units”). The number of Surviving Partnership LP Units shall be equal to 99.0% of the number of GP Units outstanding at and immediately before the OP Effective Time and 100% of the number of LP Units outstanding at and immediately before the OP Effective Time. After the OP Effective Time and pursuant to the Surviving Partnership Agreement, the Surviving Partnership LP Units shall not be convertible into Company Shares of the Company or the Surviving Entity.

(e) Series B Preferred Units. The OP Merger shall have no effect on the Operating Partnership’s outstanding Series B Preferred Units, and at and after the OP Effective Time, the Series B Preferred Units shall be the outstanding Series B Preferred Units of the Surviving Partnership.

(f) Series A Preferred Units. Upon the Operating Partnership’s distribution of the Series A Shares to the Company in exchange for the Series A Preferred Units in accordance with Section 2.1(d), the Operating Partnership shall take such actions as are necessary to cancel the Series A Preferred Units. In the event the Company takes such other actions as are permitted pursuant to the last sentence of Section 2.1(f), the Operating Partnership shall take such actions as are necessary to effectuate the intent of the foregoing.

The most recent financial statements contained in the Company SEC documents filed with the SEC prior to the date of this Agreement reflect adequate accrued liabilities for all material Taxes due and payable by the Company and the Company Subsidiaries as a group for all taxable periods and portions thereof through the date of such financial statements.

Except as set forth in Section 3.1(k)(ii) of the Company Disclosure Letter, the assets owned by the Company and the Company Subsidiaries on

the date hereof are comprised of assets described in Section 856(c)(4) of the Code.

Each Company Subsidiary which is a corporation has been since its formation classified as a qualified REIT subsidiary under Section 856(i) of the Code. Neither the Company nor any Company Subsidiary holds any asset (x) the disposition of which would be subject to rules similar to Section 1374 of the Code as announced in IRS Notice 88-19 or Treasury Regulation Section 1.337(d)-5t or (y) that is subject to a consent filed pursuant to Section 341(f) of the Code.

Section 5.3. Tax Treatment.

(a) Unless required by Law (as evidenced by the legal opinion of a nationally recognized U.S. law firm reasonably acceptable to the Purchaser Parties and the Company), neither the Purchaser Parties, on the one hand, nor the Company and the Operating Partnership, on the other hand, will take or omit to take any action, or permit any status to exist, prior to the Effective Time, that would or may jeopardize, or that is inconsistent with, the Company’s status as a REIT under the Code or the status of the Operating Partnership or any applicable Company Subsidiary as a partnership for purposes of Taxes for any period.

(b) Notwithstanding anything to the contrary contained in this Agreement, prior to the Effective Time, the Company, each Company Subsidiary and any Affiliate of any of them, shall be permitted to take or omit to take any action, or permit any status to exist, in order to maintain the Company’s status as a REIT under the Code or the status of the Operating Partnership or any Company Subsidiary as a partnership for purposes of Taxes for any period.

(c) The Purchaser Parties shall prepare and file, on a timely basis (or cause to be prepared and filed on a timely basis), all federal and state income Tax Returns and shall use their commercially reasonable efforts to so prepare and file (or cause to be prepared and filed) all

other Tax Returns and reports required to be filed from and after the Effective Time (whether such return or report related to a time period prior to, at or after the Effective Time) for the Company and the Company Subsidiaries (i) in good faith and (ii) except as contemplated in Section 3.2(h) hereof, with respect to any federal income Tax Return of the Company for the first taxable year ending on or after the Effective Time, on a basis and in a manner that preserves the qualification of the Company as a REIT within the meaning of Section 856 of the Code.

(d) The Company shall not, nor shall the Company permit any Company Subsidiary to, change in any material respect any of its methods of reporting income or deductions for federal income tax purposes from those employed in the preparation of its federal income tax return for the taxable year ended December 31, 2003, except as may be required by applicable Law or except for such changes that would reduce consolidated federal taxable income or alternative minimum taxable income.

Section 5.4. No Solicitation of Transactions.

(a) After the date hereof, the Company shall not, nor shall it permit any Company Subsidiary to, nor shall it authorize or permit any officer, director, trustee or employee of, or any investment banker, attorney or other advisor or representative of, the Company or any Company Subsidiary to (i) solicit or initiate, encourage, or facilitate, directly or indirectly, any inquiries relating to, or the submission of, any proposal or offer, whether in writing or otherwise, from any person other than the Purchaser Parties or any Affiliates thereof (a “Third Party”) to acquire beneficial ownership (as defined under Rule 13(d) of the Exchange Act) of all or more than 15% of the assets of the Company and the Company Subsidiaries, taken as a whole, or 15% or more of any class of equity securities of the Company or the Operating Partnership pursuant to a merger, consolidation or other business combination, sale of shares of beneficial interests, sale of assets, tender offer, exchange offer or similar transaction or series of related transactions, which is structured to permit such Third Party to acquire beneficial ownership of more than 15% of the assets of the Company and the Company Subsidiaries, taken as a whole, or 15% or more of any class of equity securities of the Company or the Operating Partnership (a “Competing Transaction”); (ii) participate in any discussions or negotiations regarding, or furnish to any person any information or data with respect to or access to the properties of the Company or any Company Subsidiary (other than such access which is granted to all Persons) with respect to, or take any other action to knowingly facilitate the making of any proposal that constitutes, or may reasonably be expected to lead to, any Competing Transaction; or (iii) enter into any agreement (written or oral) with respect to any Competing Transaction, approve or recommend or resolve to approve or recommend any Competing Transaction or enter into any agreement (written or oral) requiring it to abandon, terminate or fail to consummate the REIT Merger, the OP Merger and the other transactions contemplated by this Agreement; provided, however, that notwithstanding anything to the contrary contained in this Agreement, the Company may participate in ordinary course investor relations discussions relating to ordinary course transactions in the Company’s equity securities. Notwithstanding the foregoing sentence, prior to the Effective Time, if the Company receives an unsolicited bona fide, written proposal or offer for a Competing Transaction by a Third Party, which the Company Board determines in good faith (after consulting the Company Board’s independent financial advisor and independent legal counsel) (A) is on terms which are more favorable from a financial point of view to the holders of Common Shares than the REIT Merger and the other transactions contemplated by this

Agreement, (B) is not subject to any material contingency, including any contingency relating to financing, to which neither (1) the Company Board determines may likely be overcome or addressed nor (2) the other party thereto has reasonably demonstrated in its written offer its ability to overcome or address, including the receipt of government consents or approvals (including any such approval required under the HSR Act), and (C) is reasonably capable of being consummated (provided, that the Company, including the Company Board, and any of its advisors shall be permitted to contact such Third Party and its advisors and financing sources solely for the purpose of clarifying the proposal and any material contingencies and the capability of consummation) (a “Superior Competing Transaction”), then the Company may, in response to an unsolicited request therefor and subject to compliance with Section 5.4(b) and Section 5.4(c), furnish information with respect to the Company and the Company Subsidiaries to, and participate in discussions and negotiations directly or through its representatives with, such Third Party, subject to a confidentiality agreement not less favorable to the Company than the confidentiality and standstill agreement referred to in Section 5.1. Nothing contained in this Agreement shall prevent the Company Board from complying with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act or from making any other disclosure required by applicable Law.

(b) The Company and each of the Company Subsidiaries will cease and cause to be terminated any existing discussions or negotiations with any Persons conducted or commenced heretofore with respect to, or that could be expected to lead to, a Superior Competing Transaction and will cause each of their respective trustees, directors, officers, employees, advisors, consultants and agents to comply with such obligations.

(c) The Company shall advise the Purchaser Parties orally and in writing of (i) any Competing Transaction or any inquiry with respect to or which could reasonably be expected to lead to any Competing Transaction received by any officer or trustee of the Company or, to the Knowledge of the Company, any employee, financial advisor, attorney or other advisor or representative of the Company or any Company Subsidiary, (ii) the material terms of such Competing Transaction (including a copy of any written proposal) and (iii) the identity of the person making the proposal or offer for any such Competing Transaction or inquiry promptly following receipt by the Company or any officer or trustee of the Company or, to the Knowledge of the Company, any employee, financial advisor, attorney or other advisor or representative of the Company or any Company Subsidiary of such Competing Transaction proposal or inquiry. The Company will keep the Purchaser Parties informed of the status and details of any such Competing Transaction proposal or inquiry in a timely manner. None of the Purchaser Parties or their respective affiliates or advisors shall contact any Person regarding such Competing Transaction or otherwise interfere with such Competing Transaction.

Section 5.5. Public Announcements. The Company and the Purchaser Parties shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement or any of the transactions contemplated by the Transaction Documents and shall not issue any such press release or make any such public statement without the prior consent of the other party, which consent shall not be unreasonably withheld or delayed; provided, however, that a party may, without the prior consent of the other party, issue such press release or make such public statement as may be required by Law or the applicable rules of any stock exchange if it has used its commercially reasonable efforts to

consult with the other party and to obtain such party’s consent but has been unable to do so in a timely manner. In this regard, the parties shall make a joint public announcement of the transactions contemplated by the Transaction Documents no later than (i) promptly after the close of trading on the New York Stock Exchange on the day this Agreement is signed, if such signing occurs during regular business hours on a Business Day or (ii) prior to the opening of trading on the New York Stock Exchange on the Business Day following the date on which this Agreement is signed, if such signing does not occur during a Business Day.

Section 5.6. Transfer and Gains Taxes; Shareholder Demand Letters. The Purchaser Parties shall, with the Company’s good faith cooperation and assistance, prepare, execute and file, or cause to be prepared, executed and filed, all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added stock transfer and stamp taxes, any transfer, recording, registration and other fees and any similar taxes which become payable in connection with the transactions contemplated by this Agreement (together, with any related interests, penalties or additions to tax, “Transfer and Gains Taxes”). From and after the Effective Time, the Purchaser Parties shall cause the Operating Partnership to pay or cause to be paid all Transfer and Gains Taxes.

Section 5.7. Employee Arrangements; Accrued Bonuses; Employee Brokerage Arrangements.

(a) Company Severance Agreements. On the Closing Date, the Operating Partnership shall pay or cause to be paid (and the Purchaser Parties agree and acknowledge that Company shall pay or cause to be paid) the amounts due to certain of the Company’s or the Operating Partnership’s executive officers and other employees (designated as “key employees” in Section 5.7(a) of the Company Disclosure Letter) under such executive officers’ and other employees’ Company Severance Agreements for such “key employee”, as set forth in Section 5.7(a) of the Company Disclosure Letter and in accordance with such Company Severance Agreements (the “Designated Severance”); provided, that the aggregate amount to be paid pursuant to this sentence shall not exceed Three Million Seven Hundred Thousand Dollars ($3,700,000), plus any other amounts permitted below (the “Severance Cap”); provided, further, that if the Company or the Operating Partnership incurs any obligations under any Company Severance Agreement between the date hereof and the Effective Time for such “key employees” (other than as set forth in the last proviso of this sentence), the Severance Cap shall be reduced by a corresponding amount; provided, further, to the extent that persons employed by the Company or any Company Subsidiary other than the “key employees” identified in Section 5.7(a) of the Company Disclosure Letter are terminated at the request of the Purchaser Parties after the date hereof, the Company or the Operating Partnership shall pay all amounts due under any Company Severance Agreement applicable to such persons and such amounts shall be in addition to the Severance Cap provided, further, that to the extent the Severance Cap (as reduced pursuant to the preceding provisos) exceeds the amount of the Designated Severance payable pursuant to the terms hereof, the Company may, in its sole discretion, pay such excess to employees of the Company or the Company Subsidiaries. Notwithstanding anything in this Agreement to the contrary, the Company and/or the Operating Partnership shall have the right in their sole discretion at any time after the date of this Agreement and prior to the Effective Time, to enter into letter agreements with, or provide letters to (the “Severance Letter Supplements”), those persons identified in Section 3.1(1)(xiv) of the Company Disclosure Letter under Item 2(a)

(Six Month Severance Letters) and Item 2(b) (Four Month Severance Letters), extending on the same terms and conditions the term of the Company Severance Agreements applicable to those persons through to a date no later than December 31, 2005. The Purchaser Parties shall have the right, prior to the Closing Date, to contact and meet with any or all of the employees of the Company, the Operating Partnership or the Company Subsidiaries regarding employment in the Purchaser Parties’ sole discretion with the Surviving Entity, the Surviving Partnership or any of the Company Subsidiaries subsequent to the Closing Date; provided, that such contact and meetings shall be coordinated through the Company’s chief executive officer or general counsel. The Company shall, and shall cause the Operating Partnership and the Company Subsidiaries to, assist and cooperate with the Purchaser Parties in such efforts, including without limitation, by providing the Purchaser Parties and their representatives with access to all such employees during normal business hours upon reasonable notice.

(b) Benefit Plans.

(i) Upon and after the Effective Time, the Parent shall cause the Surviving Entity (or its successors or assigns) to continue in effect the Company Employee Benefit Plans and provide benefits to the employees of the Company that are substantially similar in all material respects, on an aggregate basis, to the Company Employee Benefit Plans in which such employees participated prior to the Effective Time for a period of not less than one year. As of the Effective Time, a trustee and an administrator of Company Employee Benefit Plans will be designated by the Purchaser Parties. With respect to any Company Employee Benefit Plan which is an “employee benefit plan” as defined in Section 3(3) of ERISA and any other service based benefits (including vacations) in which the employees of the Company may participate at any time after the Effective Time, solely for purposes of determining eligibility to participate, vesting and entitlement to benefits but not for purposes of accrual of benefits (except in the case of accrued vacation, sick or personal time), service with the Company or any Company Subsidiary shall be treated as service with each of the Purchaser Parties; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits under both a Company Employee Benefit Plan and a benefit plan of any Purchaser Party (or is not otherwise recognized for such purposes under the benefit plans of Purchaser Party). Without limiting the foregoing, the Purchaser Parties shall not treat any Company employee as a “new” employee for purposes of any pre-existing condition exclusions, waiting periods, evidence of insurability requirements or similar provision under any health or other welfare plan, and shall make appropriate arrangements with their insurance carrier(s), to the extent applicable, to ensure such result.

(ii) Effective as of the Closing Date, the Company or the Purchaser Parties shall, or shall cause the Company or the Surviving Entity, to take all necessary actions to fully vest the account balances and benefits of all individuals who are employed by the Company or any Company Subsidiary on the Closing Date under any Company Pension Plan (excluding any such plan that is a “multiemployer plan” as defined in Section 4001(a)(3) of ERISA) in which such employees participate. With respect to any employees of the Company or a Company Subsidiary whose employment is terminated on or after the Closing Date and not employed by the Surviving Entity (the

“Terminated Employees”), Parent shall, or shall cause the Surviving Entity to, (i) distribute or cause to be distributed to such Terminated Employees such notices and forms that are provided to participants who incur a severance from employment so that such Terminated Employees may elect to receive a distribution of their benefits under any Company Pension Plan in which such Terminated Employees participate or rollover such benefits to an “eligible retirement plan,” as defined in Section 402(c)(8)(B) of the Code and shall promptly cooperate with such Terminated Employees in effecting the foregoing and (ii) be responsible for all liabilities and obligations in connection with the continuation coverage requirements, including notice requirements, of Section 4980B of the Code and Part 6 of Subtitle B of Title I of Employee Retirement Income Security Act of 1974, as amended (“COBRA”) with respect to such Terminated Employees (and their dependents) who participate in any Company Employee Benefit Plan that is subject to COBRA, including, but not limited to, any “qualified beneficiary” (within the meaning of COBRA) who is receiving COBRA coverage as of the Closing Date. With respect to any Terminated Employee who elects COBRA coverage, Parent shall pay, or shall cause the Surviving Entity to pay, for the period set forth for each such Terminated Employee in Section 5.7(b)(ii) of the Company Disclosure Letter, the full cost of any premium or other costs associated with such COBRA coverage.

(c) Employee Loans. Except as set forth in Section 5.7(c) of the Company Disclosure Letter, prior to the Effective Time, the Company shall use its commercially reasonable efforts to cause each officer, trustee, director or employee who has any outstanding loan (other than a 401(k) loan) from, or other debt obligations to, the Company or any Company Subsidiary, for any purpose, to repay such loan in accordance with the terms thereof.

(d) Company Options. The Company and each Company Subsidiary shall take such actions as are necessary under the Company Share Incentive Plan to effect the Company Option cancellations described in Section 2.3 and shall comply with all requirements regarding tax withholding in connection therewith. In addition to the foregoing and subject to the terms of the Company Share Incentive Plan and applicable Law, the Company and the Operating Partnership shall take such actions as are necessary to cause the Company Share Incentive Plan to be terminated at or prior to the REIT Effective Time, and to reasonably satisfy Parent that no holder of Company Options or other awards under such plan or participant in the Company Share Incentive Plan, will have any right to acquire any interest in the Purchaser Parties or any Affiliate or Subsidiary of Parent as a result of the exercise of Company Options or other awards or rights pursuant to the Company Share Incentive Plan at or after the Effective Time.

(e) Employee Brokerage Arrangements. The Company and the Purchaser Parties agree that after the Effective Time if any of the tenants listed in Section 5.7(e) of the Company Disclosure Letter as of the date of this Agreement or in an updated Section 5.7(e) of the Company Disclosure Letter delivered to the Purchaser Parties from time to time or on the Closing Date shall execute a lease with the Surviving Entity, either of the entities owning the Bank One Center or 77 West Xxxxxx properties or any subsidiary or Affiliate thereof within 150 days of the Effective Time, the Surviving Entity shall pay, and Parent shall cause the Surviving Entity to pay, the individual whose name is opposite such tenant in Section 5.7(e) of the Company Disclosure Letter, regardless if such individual remains an employee of the Surviving

Entity or any subsidiary thereof, a brokerage commission in accordance with the terms of the agreements set forth in Section 5.7(a) of the Company Disclosure Letter. In the event that any Company Property is sold to any other Person or entity after the Effective Time and before the expiration of such 150-day period, the Company and the Purchaser Parties shall make proper provision so that such Person or entity assumes the obligations set forth in this Section 5.7(e).

(f) Employees. The Purchaser Parties shall be responsible for compliance with the Worker Adjustment and Retraining Notification Act of 1988 (the “Federal WARN Act”) and the Illinois Worker Adjustment and Retraining Notification Act (together with the Federal WARN Act, the “WARN Acts”) with respect to terminations occurring at or after the Effective Time at the request or direction of the Purchaser Parties. The Company shall refrain from causing an “employment loss” (as defined in the WARN Acts) in the 90 days prior to the Effective Time; provided, that any such “employment loss” resulting from actions taken by the Company with the consent or at the request of the Purchaser Parties shall not constitute a breach of this covenant; provided, further, that such consent shall be deemed to be given if the Purchaser Parties do not object in writing within five (5) Business Days of receipt of the written notice from the Company of its intention to take such action. The Company shall cooperate with and provide reasonable assistance to the Purchaser Parties in delivering any notices required or potentially required pursuant to any Company Severance Agreement or the WARN Acts to effectuate the termination of Company employees as of the Effective Time; provided, however, that all such notices shall indicate that the terminations shall be contingent upon the consummation of the REIT Merger.

(g) In the event the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person or entity within one (1) year after the Effective Time and shall not be the continuing or surviving entity of such consolidation or merger or (ii) transfers or conveys a majority of its properties and assets to any person or entity after the Effective Time, then, and in each such case, the Surviving Entity shall use commercially reasonable efforts so that the successors, assigns and transferees of the Surviving Entity, as the case may be, assume the obligations set forth in this Section 5.7.

Section 5.8. Indemnification; Trustees’ and Officers’ Insurance.

(a) In the event of any threatened or actual claim, action, suit, demand, proceeding or investigation, whether civil, criminal or administrative, including, without limitation, any such claim, action, suit, demand, proceeding or investigation in which any person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Closing, a trustee, director, officer, employee, fiduciary or agent of the Company or any Company Subsidiary (the “Indemnified Parties”) is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a trustee, director, officer, employee, fiduciary or agent of the Company or any Company Subsidiary, or is or was serving at the request of the Company or any Company Subsidiary as a trustee, director, officer, employee, fiduciary or agent of another corporation, partnership, joint venture, trust or other enterprise or (ii) the negotiation, execution or performance of this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Closing, the parties hereto agree to cooperate and use their commercially reasonable efforts to defend against and respond thereto. It is understood and

agreed that the Company shall indemnify and hold harmless, and after the Effective Time, Parent shall cause the Surviving Entity to, and the Surviving Entity shall, indemnify and hold harmless, as and to the full extent permitted by applicable Law, each Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorneys’ fees and expenses), judgments, fines and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, demand, proceeding or investigation, and in the event of any such threatened or actual claim, action, suit, demand, proceeding or investigation (whether asserted or arising before or after the Effective Time), (A) the Company, and after the Effective Time, Parent shall cause the Surviving Entity to, and the Surviving Entity shall, promptly pay expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the full extent permitted by law, subject to the provision by such Indemnified Party of an undertaking to reimburse the amounts so advanced in the event of a final non-appealable determination by a court of competent jurisdiction that such Indemnified Party is not entitled to such amounts, (B) the Indemnified Parties may retain one counsel reasonably satisfactory to them and the Company (except in the case of a potential conflict of interest among two or more Indemnified Parties, in which case more than one counsel may be retained), and after the Effective Time, Parent shall cause the Surviving Entity to, and the Surviving Entity shall, pay all reasonable fees and expenses of such counsel for the Indemnified Parties within 30 days after statements therefor are received and (C) the Company and the Surviving Entity will, and Parent will cause the Surviving Entity to, use their commercially reasonable efforts to assist in the defense of any such matter; provided, that neither the Company nor the Surviving Entity shall be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld or delayed); and provided further, that neither the Surviving Entity nor Company shall have any obligation hereunder to any Indemnified Party when and if, but only to the extent that, a court of competent jurisdiction shall ultimately determine, and such determination shall have become final and non-appealable, that indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law. Any Indemnified Party wishing to claim indemnification under this Section 5.8, upon learning of any such claim, action, suit, demand, proceeding or investigation, shall promptly notify the Company and, after the Effective Time, the Surviving Entity thereof; provided, that the failure to so notify shall not affect the obligations of the Company and the Surviving Entity except and only to the extent such failure to notify materially prejudices such party. The obligations pursuant to this Section 5.8(a) are in addition to, and shall in no way affect or limit, the rights to indemnification granted pursuant to the Company Charter and the Company By-laws.

(b) The Purchaser Parties agree that all rights to indemnification existing in favor of, and all exculpations and limitations of the personal liability of, the trustees, directors, officers, employees and agents of the Company and the Company Subsidiaries provided for in the Company Charter or the Company By-laws as in effect as of the date hereof with respect to matters occurring at or prior to the Effective Time, including the OP Merger and the REIT Merger, shall continue in full force and effect for a period of not less than six years from the Effective Time; provided, however, that all rights to indemnification in respect of any claims (each, a “Claim”) asserted or made within such period shall continue until the final disposition of such Claim. At or prior to the Effective Time, the Company shall obtain and pay for, at the Company’s expense, a fully paid policy or policies of directors’ and officers’ liability insurance (including side A coverage) providing ‘tail’ coverage for the Persons currently covered by the Company’s existing policies for a period of six (6) years from and after the Effective Time with

respect to claims arising from facts or events that occurred at or prior to the Effective Time, and providing at least the same coverage and amounts as, and containing terms and conditions which are not less advantageous to the covered Persons in any material respect than, the Company’s current policies.

(c) This Section 5.8 is intended for the irrevocable benefit of, and to grant third party rights to, the Indemnified Parties and shall be binding on all successors and assigns of the Purchaser Parties. Each of the Indemnified Parties shall be entitled to enforce the covenants contained in this Section 5.8, each of which such covenants shall survive the Closing Date.

(d) In the event that the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person or entity after the REIT Effective Time and shall not be the continuing or surviving entity of such consolidation or merger or (ii) transfers or conveys a majority of its properties and assets to any person or entity after the REIT Effective Time, then, and in each such case, proper provision shall be made so that the successors, assigns and transferees of the Surviving Entity, as the case may be, assume the obligations set forth in this Section 5.8.

(e) To the extent permitted by law, all rights of indemnification for the benefit of any Indemnified Party shall be mandatory rather than permissive.
