RECITALS:

The Board of Trustees of Parent and the sole Member of the Purchaser have approved the merger (the “Merger”) of the Purchaser into the Partnership on the terms and subject to the conditions set forth in this Agreement, whereby each unit of limited partner interest in the Partnership (the “Units”) outstanding immediately before the closing of the Merger, shall be converted into the right to receive an amount in cash equal to the Merger Price.

The Board of Directors of the General Partner has determined that the Merger is fair to, and in the best interests of, the holders of Units, has approved the Merger and resolved to recommend that holders of Units approve this Agreement and the Merger.

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and other terms contained in this Agreement, the parties hereto, intending to be legally bound hereby, agree as follows:

ARTICLE I

THE MERGER

1.01 The Merger. On the terms and subject to the conditions set forth in this Agreement, and in accordance with the Delaware Revised Uniform Limited Partnership Act (the “DRULPA”) and the Delaware Limited Liability Company Act (the “DLLCA”), the Purchaser shall be merged with and into the Partnership at the Effective Time. At the Effective Time, the

separate limited liability company existence of the Purchaser shall cease and the Partnership shall continue as the survivor (as such, the “Survivor”) and a wholly-owned subsidiary of Parent.

1.02 Closing. Subject to the satisfaction or waiver of all of the conditions set forth in Article VII, the closing (the “Closing”) of the Merger shall take place at the offices of ▇▇▇▇▇▇▇▇ & Worcester LLP at 10:00 a.m. on the business day following the satisfaction (or, to the extent permitted by Law, waiver) of the conditions set forth in Article VII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or, to the extent permitted by Law, waiver of those conditions), or at such other place, time and date as shall be agreed in writing between Parent and the Partnership. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

1.03 Effective Time. On the Closing Date the Partnership shall file with the Secretary of State of the State of Delaware, a certificate of merger (the “Certificate of Merger”) executed in accordance with the relevant provisions of the DRULPA and the DLLCA and shall make all other filings or recordings required under the DRULPA and the DLLCA. The Merger shall become effective at such time as the Certificate of Merger is duly filed with such Secretary of State of Delaware (the time the Merger becomes effective being the “Effective Time”).

1.04 Effects. The Merger shall have the effects set forth in Section 17-211 of the DRULPA and Section 18-209 of the DLLCA.

1.05 Agreement of Limited Partnership.

(a) The certificate of limited partnership of the Partnership shall be the certificate of limited partnership of the Survivor until thereafter changed or amended in accordance with the provisions thereof and applicable Law.

(b) The Amended and Restated Agreement of Limited Partnership of the Partnership (“Partnership Agreement”) as in effect immediately prior to the Effective Time shall be the agreement of limited partnership of the Survivor until thereafter changed or amended in accordance with the provisions thereof and applicable Law.

1.06 General Partner. On the Closing Date, pursuant to the Purchase Agreement, the General Partner shall withdraw from the Partnership and the Successor GP shall be admitted to the Partnership as a successor general partner.

ARTICLE II

EFFECT ON THE UNITS AND THE EQUITY INTERESTS IN
THE PURCHASER; EXCHANGE OF CERTIFICATES

2.01 Effect on Interests. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any Units, the equity interests in Purchaser or the general partner interest in the Partnership:

(a) Membership interests of Purchaser. Each issued and outstanding membership interest in Purchaser shall be converted into one newly issued Unit of the Survivor.

(b) Conversion of Units.

(i) Each Unit issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive an amount in cash equal to 91.5% of the quotient which results by dividing:

(x)

two hundred fifty million dollars ($250,000,000), increased or decreased, as the case may be, by the Working Capital Adjustment (but not decreased to less than two hundred forty-five million dollars ($245,000,000)) (the “Gross Merger Consideration”), by

(y)

the sum of (1) the total number of Units outstanding immediately prior to the Effective Time, plus (2) the total number of Units for which Unit Options outstanding immediately prior to the Effective Time are then exercisable

(such quotient, the “Merger Price”), without interest, less any withholding (as provided in Section 2.02(g)), upon surrender and exchange of the Certificate representing such Unit.

(ii) As of the Effective Time, all such Units shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a Certificate representing any such Units shall cease to have any rights with respect thereto, except the right to receive the Merger Price, without interest, less any required withholding taxes, upon surrender of such Certificate in accordance with Section 2.02.

(c) Unit Options. All Unit Options outstanding immediately prior to the Effective Time shall be cancelled and shall cease to exist, and each holder of a Unit Option shall cease to have any rights with respect thereto, except as provided in Section 6.07.

(d) General Partner Interest. The general partner interest in the Partnership shall remain outstanding as a general partner interest of the Survivor and no payment or distribution shall be made by the Partnership with respect thereto.

2.02 Exchange of Certificates.

(a) Paying Agent. Prior to the Effective Time, Parent shall select a bank or trust company reasonably acceptable to the Partnership to act as paying agent (the “Paying Agent”) for the payment of the Merger Price upon surrender of Certificates. The Purchaser shall, and Parent shall cause the Purchaser to, deposit with the Paying Agent prior to the Effective Time, an amount in cash which, together with the Deposit, is equal to the aggregate Merger Price payable to holders of all the Units converted pursuant to Section 2.01(b) (such cash, inclusive of the Deposit, being hereinafter referred to as the “Exchange Fund”). The expenses of the Paying Agent shall not be paid from the Exchange Fund, but shall be paid directly by the Purchaser.

(b) Exchange Procedure. As soon as reasonably practicable after the Effective Time, the Survivor shall cause the Paying Agent to mail to each holder of record of Units whose Units were converted into the right to receive the Merger Price pursuant to Section 2.01(b), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the certificate or certificates that immediately prior to the Effective Time represented outstanding Units (the “Certificates”) shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify), and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Price. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by the Survivor, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor cash in an amount equal to the product of (A) the number of Units theretofore represented by such Certificate, and (B) the Merger Price, and the Certificate so surrendered shall forthwith be canceled. No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate. For purposes of this Article II, the Successor GP shall be deemed to be the record owner of all Units purchased pursuant to the Purchase Agreement.

(c) No Further Ownership Rights in Units; Transfer Books. The Merger Price paid in accordance with the terms of this Article II upon conversion of Units shall be deemed to have been paid in full satisfaction of all rights pertaining to such Units, subject, however, to the Survivor’s obligation to pay any distributions with a record date prior to the Effective Time that may have been declared or made by the Partnership on such Units in accordance with the terms of this Agreement and which remain unpaid at the Effective Time, and after the Effective Time there shall be no further registration of transfers on the transfer books of the Survivor of Units that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates are presented to the Survivor or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article II.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest or other income received by the Paying Agent in respect thereof that has not previously been distributed pursuant to Section 2.02(f)) that remains undistributed to the holders of Units for one hundred eighty (180) days after the Effective Time shall be delivered to the Survivor, upon demand, and any holder of Units who has not theretofore complied with this Article II shall thereafter look only to the Survivor for payment of such holder’s claim for the Merger Price.

(e) No Liability. None of Parent, Purchaser, the General Partner, the Successor GP, the Partnership, the Survivor or the Paying Agent shall be liable to any person in respect of any payments or distributions payable from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(f) Investment of Exchange Fund. The Paying Agent shall invest any cash included in the Exchange Fund, as directed by the Survivor, on a daily basis; provided, however, that substantially all of such investments shall be in obligations of or guaranteed by the United

States of America, in commercial paper obligations receiving the highest rating from either ▇▇▇▇▇’▇ Investors Service, Inc. or Standard & Poor’s Ratings Group, or in certificates of deposit, bank repurchase agreements or bankers’ acceptances of commercial banks with capital exceeding One Billion Dollars ($1,000,000,000) (collectively, “Permitted Investments”) or in money market funds which are invested solely in Permitted Investments; provided further, however, that the maturities of Permitted Investments shall be such as to permit the Paying Agent to make prompt payment of the Merger Price at and after the Effective Time. Any interest and other income resulting from such Permitted Investments shall be payable to the Survivor on demand.

(g) Withholding Rights. Parent, Purchaser or the Survivor shall be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, from the consideration otherwise payable to any holder of Units pursuant to this Agreement, (i) such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or under any provision of state, local or foreign Law, and (ii) such amounts as may be required to be deducted or withheld from or paid by holders of Units upon the order of the Court of Chancery of the state of Delaware, New Castle County in connection with the Litigation. To the extent that amounts are so deducted and withheld by Parent, Purchaser or the Survivor, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Units in respect of which such deduction and withholding was made by Parent, Purchaser or the Survivor.

(h) Transfers of Units. If the Merger Price (or any portion thereof) is to be paid to a person other than the person in whose name the Certificate surrendered in exchange therefor is registered, it shall be a condition to the payment of the Merger Price that the Certificate so surrendered shall be properly endorsed or accompanied by appropriate stock powers or assignments (with signatures guaranteed in accordance with the transmittal form) and otherwise in proper form for transfer, that such transfer otherwise be proper and that the person requesting such transfer pay to the Paying Agent any transfer or other Taxes payable by reason of the foregoing or establish to the satisfaction of the Paying Agent that such Taxes have been paid or are not required to be paid.

(i) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Survivor, the posting by such person of a bond, in such reasonable amount as the Survivor may direct, as indemnity against any claim that may be made against Parent or the Survivor with respect to such Certificate, the Paying Agent will pay, in exchange for such lost, stolen or destroyed Certificate, the Merger Price to be paid in respect of the Units represented by such Certificate, as contemplated by this Article II.

(iii) neither the Partnership nor any Subsidiary Partnership (including for this purpose any partnership or disregarded entity for tax purposes in which the Partnership or any Subsidiary Partnership directly or indirectly held or holds an interest) has received or accrued, or will receive or accrue, directly or indirectly, any rent or interest with respect to real or personal property, including base rent, percentage rent or any other amount received or accrued in the nature of rent or interest, where the determination of the amount of rent or interest depends in whole or in part on the income or profits derived by any person from the property, except where rent or interest is based on a fixed percentage or percentages of receipts or sales within the meaning of Section 856(d)(2)(A) or Section 856(f)(1)(A) of the Code;

(iv) any sublease interest entered into between the Partnership’s or any Subsidiary Partnership’s (including for this purpose any partnership or disregarded entity for tax purposes in which the Partnership or any Subsidiary Partnership directly or indirectly held or holds an interest) tenants and their subtenants has not been based and will not be based, in whole or in part, on the income or profits of any person; and

(v) each of the Partnership and each Subsidiary Partnership (including for this purpose any partnership or disregarded entity for tax purposes in which the Partnership or any Subsidiary Partnership directly or indirectly held or holds an interest) has not received or accrued, and will not receive or accrue, directly or indirectly, rent or any other consideration under a lease from any person in which the Partnership or any Subsidiary Partnership (including for this purpose any partnership or disregarded entity for tax purposes in which the Partnership or any Subsidiary Partnership directly or indirectly held or holds an interest) owned or owns (a) in the case of a corporation, 9.5 percent or more of the total combined voting power of all classes of stock entitled to vote, or 9.5 percent or more of the value or total number of shares of all classes of stock, or (b) in the case of an entity other than a corporation, an interest of 9.5 percent or more in the assets or net profits of such entity (it being understood that for purposes of determining ownership in the Partnership or any Subsidiary Partnership, in a tenant or in any other person, the constructive ownership rules specified in Section 318 of the Code (as modified by Sections 856(d)(5) and 7704(d)(3)(B) of the Code) shall apply).

(b) Except as will not and could not reasonably be expected to have, individually or in the aggregate, a Partnership Material Adverse Effect, each of the Partnership and each Subsidiary has timely filed, or has caused to be timely filed on its behalf, all Tax Returns (including those returns requiring estimates of Tax payments) required to be filed by it, and all such Tax Returns are true, complete and accurate in all material respects.

5.02 No Solicitation.

(a) From the date hereof, the General Partner (whether directly or indirectly through advisors, agents, representatives or other intermediaries) shall not and shall use its reasonable best efforts to cause its officers, directors, advisors, representatives and other agents (collectively, its “Representatives”) not to, directly or indirectly, (i) continue any discussions or

negotiations, if any, with any parties, other than Parent and Purchaser, conducted heretofore with respect to any Partnership Takeover Proposal or which could reasonably be expected to lead to a Partnership Takeover Proposal, (ii) solicit, initiate or knowingly encourage any inquiries relating to, or the submission of, any Partnership Takeover Proposal, (iii) participate in any discussions or negotiations regarding any Partnership Takeover Proposal, or, in connection with any Partnership Takeover Proposal, furnish to any person any information or data with respect to or access to the properties of the Partnership or any Subsidiary, or (iv) enter into any agreement with respect to any Partnership Takeover Proposal. Nothing contained in this Section 5.02 shall prohibit the General Partner or its Representatives from (x) taking and disclosing a position with respect to a tender offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated by the SEC under the Exchange Act, or (y) furnishing information including nonpublic information to, or entering into negotiations or discussions with, any person that has indicated its willingness to make an unsolicited bona fide Partnership Takeover Proposal, if, and only to the extent that, (A) the Board of Directors of the General Partner determines in good faith, after consultation with its outside legal counsel and its independent financial advisors, that the Partnership Takeover Proposal may constitute, or could reasonably be expected to lead to, a Superior Partnership Proposal, (B) contemporaneously with furnishing such information to, or entering into discussions or negotiations with, such person, the Partnership provides written notice to Parent to the effect that it is furnishing information to, or entering into discussions or negotiations with, such person and (C) the Partnership uses all reasonable efforts to keep Parent informed in all material respects of the status and terms of any such negotiations or discussions (including the identity of the person with whom such negotiations or discussions are being held). Nothing in this Section 5.02 shall restrict or limit the obligations of defendants in the Litigation to comply with any discovery obligations in those actions. To the extent permitted by applicable court orders, the Partnership will provide Purchaser copies of all discovery materials provided to the plaintiffs in those actions after the date of this Agreement.

(b) For purposes of this Agreement:

“Partnership Takeover Proposal” means any inquiry, proposal or offer (other than by Parent, Purchaser or any of their affiliates) relating to, or that could reasonably be expected to lead to (i) a merger, consolidation, share exchange of securities, dissolution, recapitalization, liquidation or other business combination involving the Partnership, (ii) the acquisition by any person in any manner, directly or indirectly, of a number of shares of any class of equity securities of the Partnership equal to or greater than 15% of the Units outstanding before such acquisition or (iii) the acquisition in any manner, directly or indirectly, in a single transaction or in a series of related transactions, of assets that generate or constitute 20% or more of the net revenues, net income or assets of the Partnership and its Subsidiaries (taken as a whole), in each case other than the Other Transactions.

“Superior Partnership Proposal” means any bona fide written Partnership Takeover Proposal made by a third party (other than by Parent, Purchaser or any of their affiliates) to acquire directly or indirectly (i) a majority of the equity securities or (ii) the assets of the Partnership substantially as an entirety, which the Board of Directors of the General

Partner determines in good faith (after consultation with its independent financial advisors and outside counsel), taking into account all legal, financial, regulatory and other aspects of the proposal and the person making such proposal, (x) would, if consummated, be more favorable, from a financial point of view, to the holders of Units other than the General Partner and its affiliates, than the Merger, (y) is made by a third party that has the good faith intent to proceed with negotiations, and (z) the proposal is reasonably capable of being consummated.

ARTICLE VI

ADDITIONAL AGREEMENTS

6.01 Deposit. Within ten (10) days of the execution of this Agreement, Parent will deposit $10,000,000 in escrow (the “Deposit”) with the Paying Agent. The Paying Agent shall hold the Deposit in accordance with the terms of an agreement among Parent, the Partnership and the Paying Agent which shall provide, among other things, (a) if the transactions contemplated by this Agreement are consummated, the Paying Agent shall cause the Deposit to be applied as part of the aggregate Merger Price, or (b) if this Agreement is terminated pursuant to Section 8.01, the Paying Agent shall cause the Deposit to be repaid to Parent.

6.02 Inspection of and Access to Information. For 30 days following the date of this Agreement (the “Inspection Period”) and thereafter until the Effective Time upon reasonable notice, the Partnership will and will cause each of the Subsidiaries to permit Parent and its representatives to inspect, during the Partnership’s normal business hours, the Partnership Real Property (including, without limitation, all roofs, electric, mechanical and structural elements, and HVAC systems therein), to perform due diligence, soil analysis and environmental investigations (including subsurface investigations), to examine the Contracts, books, records and other information of the Partnership and the Subsidiaries, including, without limitation, the Partnership Leases and all other Contracts affecting the Partnership Real Property, and make copies thereof, at such reasonable times as Parent or its representatives may reasonably request by notice to the Partnership (which notice may be oral). If Parent gives the Partnership notice on or before the 25^th day following the date of this Agreement that it requires additional time to complete its diligence, the Inspection Period will extend to the 45^th day following the date of this Agreement. To the extent that, in connection with such investigations, the Parent, its agents, representatives or contractors, damages or disturbs any of the Partnership Real Property, Parent shall return the same to substantially the same condition which existed immediately prior to such damage or disturbance. In addition, during the period after the date of this Agreement and prior to the Effective Time, the Partnership agrees to provide to Parent with such operating information, from time to time, as Parent may reasonably request, regarding the Partnership Real Property and the condition and operation thereof. Prior to the expiration of the Inspection Period, Parent may give the Partnership notice of any structural, physical, environmental, legal or other defects or conditions (including, without limitation, any fact or condition which would constitute a breach of any of the representations, warranties or covenants of the Partnership contained herein, which breach shall be determined as though such representations and warranties were made as of the last day of the Inspection Period and without giving effect to any

qualification as to “materiality” or “Partnership Material Adverse Effect” or “knowledge” set forth therein) which affect any of the Partnership Real Property in any material respect and which has not been disclosed in the Partnership Disclosure Letter (each a “Defect”). Parent’s failure to give notice of any Defect (absent the then actual, present knowledge of ▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Executive Vice President of Parent, or ▇▇▇▇▇ ▇. ▇▇▇▇▇▇, Senior Vice President of Parent, of such Defect) shall not restrict Parent from terminating this Agreement pursuant to Section 8.01(d)(v).

6.03 Title and Survey Matters.

(a) Title Matters. The Partnership has obtained title insurance policies (the “Title Policies”) with respect to each Partnership Owned Property and, except as set forth in Section 6.03 of the Partnership Disclosure Letter, has provided Purchaser true and complete copies of (i) the Title Policies, and (ii) all instruments, documents or agreements referenced in the Title Policies and in the possession of the Partnership that create or evidence conditions or exceptions to title affecting the Partnership Owned Property. Prior to the expiration date of the Inspection Period, Parent shall give the Partnership notice of any title exceptions (whether the same appear in Title Polices or any other title commitment or title report obtained by Parent), other than Permitted Encumbrances, Liens under the Mortgage Documents related to those loans listed in Section 3.05(a)(ii) of the Partnership Disclosure Letter, Liens for Taxes not yet due and payable and Liens of mechanics and materialmen for goods and services for amounts not then due and payable, and of any other matters which adversely affect any of the Partnership Owned Property as to which Parent reasonably objects (each a “Title Defect”).

(b) Survey Matters. The Partnership has obtained an ALTA survey with respect to each Partnership Owned Property (the “Surveys”) by a licensed surveyor in the jurisdiction in which each Partnership Owned Property is located and has provided Purchaser true and complete copies of the Surveys. Prior to the expiration of the Inspection Period, Parent shall give the Partnership notice of any matters shown on such Surveys (or any updates to such Surveys or new surveys obtained by Parent) or any other zoning or land use matter (other than Permitted Encumbrances and matters set forth in the Partnership Disclosure Letter) which adversely affect any of the Partnership Owned Property in any material respect and as to which Parent reasonably objects (each a “Survey Defect”).

(i) On or before the Closing Date, the Partnership shall pay-off or otherwise discharge of record all monetary Encumbrances (other than the Encumbrances specified in Section 6.03(c) of the Partnership Disclosure Letter) and any Encumbrance (other than the Encumbrances specified in Section 6.03(c) of the Partnership Disclosure Letter) created by, through or under the Partnership, its Subsidiaries, affiliates or agents after the date hereof.

(ii) With respect to all other Defects, Title Defects and Survey Defects, the Partnership shall take all commercially reasonable action required to (A) remedy such Defects such that the affected Partnership Owned Property, if any, is brought into a condition reasonably satisfactory to Parent and in accordance with prevailing standards for like properties,

and (B) cure such Title Defects and Survey Defects and cause the same to be removed from the applicable title insurance policy obtained by the Partnership or any applicable title commitment or report obtained by Parent; it being understood that it may not be commercially reasonable to, and in that case the Partnership will not be expected to, remedy or remove such items prior to the Closing Date. If for any reason the Partnership reasonably believes that the expenditures required to remedy or remove such Defects, Title Defects or Survey Defects would reasonably be expected to exceed $10,000,000, or if Parent reasonably believes that the estimated aggregate costs of remedying, curing and removing such other Defects, Title Defects and Survey Defects will exceed $10,000,000, the Partnership or Parent, as the case may be, shall have the option of electing to terminate this Agreement by written notice given at any time prior to the ^20th business day following the expiration of the Inspection Period. With respect to any Defect which arises from a breach of the representation contained in Section 3.19(d) as to rent (a “Rent Defect”), the estimated cost of remedying such Rent Defect shall be deemed to be an amount equal to the product obtained by multiplying ten (10) by the annualized amount of such Rent Defect.

6.04 Preparation of Proxy Statement; Unitholder Meeting.

(a) The Partnership shall, as soon as practicable, prepare and file with the SEC the Proxy Statement in preliminary form, and each of the Partnership and Parent shall use all reasonable efforts to respond as promptly as practicable to any comments of the SEC with respect thereto.

If at any time prior to receipt of the Unitholder Approval there shall occur any event that should be set forth in an amendment or supplement to the Proxy Statement, the Partnership shall promptly prepare and mail to its unitholders such an amendment or supplement. No filing of, or amendment to, the Proxy Statement will be made by the Partnership without providing Parent the opportunity to review and comment thereon. The Partnership shall not mail any Proxy Statement, or any amendment or supplement thereto, to which Parent reasonably objects. The Partnership shall use its reasonable best efforts to cause the Proxy Statement to be mailed to the Partnership’s unitholders as promptly as practicable after filing with the SEC.

(b) The Partnership shall, as soon as practicable after the SEC completes its review of the Proxy Statement, duly call, give notice of, convene and hold a meeting of its unitholders (the “Unitholder Meeting”) for the purpose of seeking the Unitholder Approval. Unless the Board of Directors of the General Partner determines in good faith that its fiduciary duties otherwise require, the Partnership shall, through the Board of Directors of the General Partner, recommend to its unitholders that they give the Unitholder Approval and use its reasonable efforts to obtain Unitholder Approval.

(c) If Unitholder Approval is obtained, Parent shall use all reasonable efforts to cause the Merger to be completed as soon as practicable.

(d) The Partnership, and after the Effective Time, the General Partner, shall cooperate with Parent in the preparation of any documents Parent files under the Securities Act or the Exchange Act, and for this purpose shall use commercially reasonable efforts to provide Parent with financial statements and other financial information that Parent requests relating to periods prior to the Effective Time, including such certifications with respect to such financial statements and financial information as Parent shall reasonably require, and shall afford to Parent, and to Parent’s officers, employees, accountants, and other representatives, copies of, or at Parent’s request, access during reasonable business hours to (i) all of the Partnership’s and each Subsidiary’s properties, books, personnel and records and other information and business documents, (ii) by appointment, the Partnership’s accountants and (iii) the premises of the Partnership and each Subsidiary for the purpose of inspecting the books and records of the Partnership and each Subsidiary, provided that access to the premises shall be permitted only with the prior consent of the Partnership (which consent shall not be unreasonably withheld or delayed) and provided further that Parent shall pay any third party expenses and photocopying charges incurred by the Partnership in connection with such activities. The Partnership shall have the right to have a representative present at all times of any such inspections and communications conducted by Parent or its representatives.

6.05 Access to Information; Confidentiality Agreement.

(b) At Parent’s request and cost, the Partnership and the Subsidiaries shall (i) obtain surveys, title commitments and policies, engineering reports, environmental reports, and appraisals with respect to the Partnership Real Property, and (ii) provide Parent reasonable access to the Partnership Real Property, and all documents and information regarding the Partnership Real Property.

Parent and Purchaser shall not permit any construction, mechanic’s or materialman’s liens or any other liens to attach to the Partnership Real Property or any portion thereof by reason of the performance of any work or the purchase of any materials by Parent, Purchaser or any other party in connection with any studies or tests conducted pursuant to this Section. Parent and

Purchaser shall give reasonable notice to the Partnership prior to entry onto the Partnership Real Property and shall permit the Partnership to have a representative present during all investigations and inspections conducted with respect to the Partnership Real Property. Parent and Purchaser shall take all reasonable actions and implement all reasonable protections necessary to ensure that all actions taken in connection with the investigations and inspections of the Partnership Real Property, and all equipment, materials and substances generated, used or brought onto the Partnership Real Property pose no threat to the safety of persons or the environment and cause no damage to the Partnership Real Property, any tenant or other persons. Parent and Purchaser shall indemnify, defend and hold the Partnership harmless for, from and against any and all claims, liabilities, causes of action, damages, liens, losses and expenses (including attorneys’ fees and costs) incident to, resulting from or in any way arising out of any of Parent’s, Purchaser’s or their agents’, contractors’ or representatives’ activities on the Partnership Real Property or from Parent’s or Purchaser’s breach of their obligations or agreements under this Section, excluding, however, any liability arising from the discovery or disclosure of any condition. The cost of obtaining any reports or surveys shall be borne exclusively by Parent and Purchaser.

(c) Between the date of this Agreement and the Closing Date, the Partnership will cooperate with Parent to arrange meetings with such tenants under Partnership Leases as Parent may, from time to time, reasonably request.

Without limiting the foregoing, the Partnership and its Subsidiaries shall deliver such documents or instruments (including, if necessary, authorizing resolutions or other evidence of their authority) and shall comply with such requirements as may be required of them under the terms of any Partnership Lease under which the General Services Administration or any other organization or agency of the United States is the tenant or as otherwise may be required under the regulations and policies of the United States Government in connection with the Merger, including, if applicable, the execution and delivery of a novation agreement in such form as the United States Government shall require.

(c) In the event Parent or the Survivor or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties

Parent agrees that (i) within three (3) months after the Effective Time it will cause all subsidiaries of the Survivor to take all necessary steps to change their names so as not to include, and cease doing business under any name that includes, the word “Hallwood,” or any derivative, (ii) at any time after the Effective Time, Group and its affiliates may engage in business in the real estate industry or any other activity using a name that includes the word “Hallwood,” other than a name that is identical to the name at that time of any entity that is a Subsidiary of the Partnership immediately prior to the Effective Time, and (iii) after the Effective Time Parent will and will cause all subsidiaries of the Survivor to take all necessary steps to consent to the formation by Group or its affiliates of any entity under a name, and the use of a name by that entity, that includes the word “Hallwood” in any jurisdiction, to the extent contemplated by clause (ii).

6.15 Tax Matters.

(a) The General Partner, as the Partnership’s tax matters partner (within the meaning of Section 6231 of the Code), will prepare and file all Tax Returns required to be filed by the Partnership or its Subsidiaries or delivered to the partners of the Partnership (including for avoidance of doubt (i) Internal Revenue Service Schedule K-1 and any state or local Tax Authority equivalent to said Schedule K-1, (ii) any additional reporting required pursuant to Section 6050K of the Code and (iii) any combined Tax Return filed by the Partnership on behalf of its partners), whether such preparation, filing or delivery precedes or follows the Effective Time, but only to the extent that such Tax Returns relate to Taxable periods ending on or prior to

the Closing Date; provided however that Parent shall be provided the opportunity to review and comment upon any such Tax Returns prepared, filed or delivered after the date hereof. After the Effective Time, Parent and Survivor shall cooperate with the General Partner in the preparation of all such Tax Returns, and for this purpose shall afford to the General Partner, and to the General Partner’s officers, employees, accountants, and other representatives, copies of, or at the General Partner’s request, access during reasonable business hours to (i) all of the Survivor’s and each Subsidiary’s properties, books, personnel and records and other information and business documents, (ii) by appointment, the Survivor’s accountants and (iii) the premises of the Survivor and each Subsidiary, provided that access to the premises shall be permitted only with the prior consent of the Survivor (which consent shall not be unreasonably withheld or delayed) and provided further that the General Partner shall pay any third party expenses and photocopying charges incurred by Survivor or any Subsidiary in connection with such preparation. The Survivor shall have the right to have a representative present at all times of any such inspections and communications conducted by the General Partner or its representatives.

(b) The parties hereto agree that the Merger is being effected as an expedient method for each holder of record of Units to convey its respective interest in the Partnership. The parties will treat and report, for purposes of federal income Taxes, the Merger and the Other Transactions consistently with the principles of Situation 2 of Internal Revenue Service Revenue Ruling 99-6, 1999-1 C.B. 432, and in particular (i) Parent shall treat and report the Merger and the Other Transactions as a purchase of all of the assets of the Partnership (and any applicable Subsidiary Partnership or Subsidiary Resulting LLC) and (ii) the General Partner and each holder of Units will treat the Merger and the Other Transactions as a sale of their respective partnership interest in accordance with Section 741 of the Code, and will to the extent applicable similarly treat and report the Transactions and Other Transactions for state and local income Taxes.

(c) Prior to the Closing Date, each of the Partnership and the General Partner shall use its commercially reasonable efforts to obtain, or cause the Paying Agent to obtain, from the Partnership and each partner of the Partnership (or if such partner is a “disregarded entity” for federal income Tax purposes, such partner’s first upper tier owner that is not a “disregarded entity” for federal income Tax purposes) a certificate of non-foreign status of such person meeting the requirements of the Treasury Regulations under Section 1445 of the Code.

(d) The Partnership shall use commercially reasonable efforts to cause, at least one day prior to the Closing Date, each Subsidiary set forth in Section 3.02 of the Partnership Disclosure Letter which is not also listed in Section 3.09(a) of the Partnership Disclosure Letter (each a “Subsidiary Corporation”) to have converted (in a manner which does not create adverse Tax consequences to the Purchaser or Parent) into a limited liability company organized under Delaware Law (each a “Subsidiary Resulting LLC”). Such conversion may be achieved through a transaction or series of transactions, satisfactory to the Purchaser, by conversion, contribution, merger, acquisition or otherwise, so long as (i) each Subsidiary Resulting LLC owns substantially all of the assets that were held directly or indirectly by its respective Subsidiary Corporation immediately prior to such transaction, (ii) all of the equity interests of each Subsidiary Resulting LLC are held by one or more Subsidiary Partnerships or

Subsidiary Resulting LLCs, (iii) the certificate of formation of each Subsidiary Resulting LLC is in form and substance reasonably acceptable to the Purchaser, and (iv) the limited liability company operating agreement of each Subsidiary Resulting LLC is in form and substance reasonably acceptable to the Purchaser. From and after each such conversion until Closing, each Subsidiary Resulting LLC shall be and remain a partnership or disregarded as an entity separate from its owner for U.S. federal income Tax purposes under Treasury Regulation Sections 301.7701-2 and -3 (and any comparable provision of applicable Law of state and local jurisdictions that permit such treatment).

6.16 Purchase of Receivables. Contemporaneously with the determination by the accountant of Net Working Capital, upon notice to the Successor GP from the General Partner that it desires to purchase any “accounts receivable” which is in excess of thirty (30) days past due but less than sixty (60) days past due, and payment to the Successor GP in cash of an amount equal to the face amount of such “accounts receivables” the Partnership shall transfer, without recourse or representation, such “accounts receivables” to the General Partner. Following the Effective Time, the Partnership shall use commercially reasonable efforts to collect such “accounts receivable” so transferred short of commencing or prosecuting any litigation or terminating any tenancy. If any payment on account of “accounts receivable” which has been so transferred is received by the Partnership following the Effective Time, the Partnership shall promptly remit such payment to the General Partner.

6.17 Interim Reports. Prior to the Effective Time, the Partnership shall deliver to the Purchaser, promptly after filing, a copy of any report or statement filed by the Partnership pursuant to the Exchange Act after the date of this Agreement.

The delivery of any supplement or amendment pursuant to this Section 6.17 shall not in any matter constitute a waiver by any of Parent, Purchaser, the Partnership or the General Partner of any of the conditions contained in Article VII. Additionally, the Partnership shall deliver to the Purchaser, promptly upon receipt, copies of all bills or statements for local real estate Taxes and assessments encumbering the Partnership Owned Property.
