(a) From the date hereof until the Closing, upon reasonable notice, the Sellers shall cause Gale Services, Gale Construction, the Subsidiaries and each of its officers, directors, employees, agents, representatives, accountants and counsel to (i) afford the Purchaser and its officers, directors, employees, agents, representatives, accountants and counsel (collectively, the “Purchaser Representatives”) with reasonable access to all of the offices, properties and books and records of Gale Services, Gale Construction and the Subsidiaries and (ii) furnish to the Purchaser Representatives such additional financial and operating data and other information regarding Gale Services, Gale Construction, the Subsidiaries or the Business (or copies thereof) as the Purchaser may from time to time reasonably request; provided, however, that any such access or furnishing of information shall be conducted at the Purchaser’s sole expense, during normal business hours, under the supervision of the Company’s personnel and in such a manner as not to interfere with the normal operations of the Companies, the Subsidiaries or the Business.

(b) In order to facilitate the resolution of any claims made against or incurred by the Sellers relating to the Business, for a period of seven (7) years after the Closing or, if shorter, the applicable period specified in the Purchaser’s document retention policy, the Purchaser shall (i) retain the books and records relating to the Business, Gale Services, Gale Construction and the Subsidiaries relating to periods prior to the Closing and (ii) upon reasonable notice, afford the officers, employees, agents and representatives of the Sellers reasonable access (including the right to make, at the Sellers expense, photocopies), during normal business hours, to such books and records; provided, however, that the Purchaser shall notify the Sellers at least thirty (30) days in advance of destroying any such books and records prior to the seventh

anniversary of the Closing in order to provide the Sellers the opportunity to access such books and records in accordance with this Section 5.02(b).

Section 5.03. Confidentiality.

(a) The parties hereto acknowledge and agree that all customer, prospect, and marketing lists, sales data, Intellectual Property, proprietary information, trade secrets, and other confidential information of Gale Services, Gale Construction or any Subsidiary (collectively, “Confidential Information”) (i) are valuable, special and unique assets of the Companies and the Subsidiaries and (ii) are, and following the Closing, will continue to be owned exclusively by the Companies or the Subsidiaries, as the case may be. Each party hereto agrees to, and agrees to use reasonable best efforts to cause its directors, officers, employees, partners, Affiliates, advisors and other representatives (“Representatives”) to, treat the Confidential Information, together with any other confidential information furnished to the Sellers, Gale Services, Gale Construction or the Subsidiaries by the Purchaser, on the one hand, or to Purchaser by the Sellers, Gale Services, Gale Construction or any of the Subsidiaries, on the other hand, as confidential and not to make use of such information for its own purposes other than in connection with the transactions contemplated hereby or for the benefit of any other Person (other than the Companies and the Subsidiaries and after the Closing, the Purchaser). Without limiting the generality of the foregoing and except as provided in Section 10.03 hereof, the parties expressly acknowledge and agree that the material terms of this Agreement (including, without limitation, the Purchase Price) constitute Confidential Information, and, in any event, unless otherwise publicly disclosed by the Purchaser, each party hereby agrees not to, and agrees to use reasonable best efforts to cause its Representatives not to, disclose such terms to any Person, except to the extent required by Law, in which case the non-disclosing parties will be given as much advance notice as reasonably possible with respect to the nature of such required disclosure. To the extent the terms in this Section 5.03 conflict with the confidentiality provisions of that certain confidentiality agreement dated as of February 17, 2006, by and between the Sellers and the Purchaser (the “Confidentiality Agreement”), the terms of this Section 5.03 shall supersede the conflicting terms in the Confidentiality Agreement. Notwithstanding anything to the contrary contained herein, the obligations of the Purchaser pursuant to this Section 5.03 shall terminate upon the Closing and the term Confidential Information does not include information which (A) is or becomes generally available to the public other than as a result of a disclosure by any of the parties hereto or their respective Representatives, (B) was available on a non-confidential basis prior to its disclosure, or (C) becomes available on a non-confidential basis from a source, other than any of the parties hereto or their respective Representatives, not known to be bound by confidentiality obligations with respect to such information.

(b) Prior to the Closing, the Sellers shall not disclose to any third party any information that is not public information concerning the Purchaser and MCRLP or any transaction or potential transaction the Seller may become aware of involving the Purchaser and MCRLP without prior written consent of the Purchaser and MCRLP.

Section 5.04. Regulatory and Other Authorizations; Notices and Consents.

(a) Each of the parties to this Agreement shall use all reasonable efforts to promptly obtain all authorizations, consents, orders and approvals of all Governmental Authorities and other third parties that may be or become necessary for its execution and delivery of, and the performance of its obligations pursuant to, this Agreement and will cooperate fully with one another in promptly seeking to obtain all such authorizations, consents, orders and approvals. None of the Sellers or the Companies shall be required to pay any fees or other payments in excess of $100,000 in the aggregate to any Governmental Authorities or other third parties in order to obtain any such authorization, consent, order or approval.

(b) Except as provided in Section 10.03, each party to this Agreement shall promptly notify the other party of any communication it or any of its Affiliates receives from, or sends to, any Governmental Authority relating to the matters that are the subject of this Agreement and permit, to the extent practicable, the other party to review in advance any proposed communication by such party to any Governmental Authority.

Section 5.05. Non-Competition; Non-Solicitation.

(a) For a period of four (4) years after the Closing (the “Restricted Period”), the Sellers shall not (and shall cause their respective Affiliates not to), in the Territory, engage, directly or indirectly, in the Business or, without prior written consent of the Purchaser, directly or indirectly, own an interest in, manage, operate, join, control, lend money or render financial or other assistance to or participate in or be connected with, as an officer, employee, partner, stockholder, consultant or otherwise, any Person engaged in the Business in the Territory; provided, however, that for the purposes of this Section 5.05, ownership of securities having no more than 4.99% of the outstanding voting power of any competitor which are listed on any national securities exchange shall not be deemed to be in violation of this Section 5.05 as long as the Person owning such securities has no other connection or relationship with such competitor. For purposes of this Section 5.05, “Territory” means worldwide, other than Boston, Massachusetts, New York County, New York and the continent of Asia.

(b) During the Restricted Period, the Sellers shall not (and shall cause their respective Affiliates not to), in the Development Territory, engage, directly or indirectly, in the business of developing real property or, without prior written consent of the Purchaser, directly or indirectly, own an interest in, manage, operate, join, control, lend money or render financial or other assistance to or participate in or be connected with, as an officer, employee, partner, stockholder, consultant or otherwise, any Person engaged in the business of developing real property in the Development Territory; provided, however, that for the purposes of this Section 5.05(b), ownership of securities having no more than 4.99% of the outstanding voting power of any competitor which are listed on any national securities exchange shall not be deemed to be in violation of this Section 5.05(b) as long as the Person owning such securities has no other connection or relationship with such competitor. For purposes of this Section 5.05, “Development Territory” means the State of New Jersey and the counties listed on Section 5.05(b) of the Disclosure Schedule.

(c) During the Restricted Period, Sellers shall not hire or attempt to hire any Person who is, or was at any time six (6) months prior to the Closing Date, employed by or associated with the Companies or the Subsidiaries as an executive, officer, employee, manager,

salesman, consultant, independent contractor, representative or other agent to engage in the Business in the Territory. Notwithstanding the foregoing, if, after the date hereof, a Person is terminated by the Companies or the Subsidiaries, then, the Sellers may freely employ such Person.

(d) If, at the time of the enforcement of this Section 5.05, a court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable under the circumstances then existing, each of the Sellers and the Purchaser agree that it is the intention of the parties hereto that such provision should be enforceable to the maximum extent permissible under applicable Law.

(e) Each of the Sellers acknowledge that the covenant of the Sellers set forth in this Section 5.05 are an essential element of this Agreement and that, but for the agreement of the Sellers to comply with the covenant, the Purchaser would not have entered into this Agreement. Each of the Sellers acknowledge that this Section 5.05 constitutes an independent covenant that shall not be affected by the performance or nonperformance of any other provision of this Agreement by the Purchaser. Each of the Sellers has independently consulted with its counsel and after such consultation agrees that the covenants set forth in this Section 5.05 are reasonable and proper.

Section 5.06. Property Management Retention. For a period of four (4) years after the Closing, each of the Sellers shall, and shall cause its Affiliates and all joint ventures in which it or its Affiliates have a controlling interest, to retain, on customary and reasonable terms as agreed to by the Sellers and the Purchaser, the Purchaser and its successors to manage the commercial office properties in the State of New Jersey identified in Section 5.06 of the Disclosure Schedule attached hereto which are owned or controlled by the Sellers, their Affiliates or such joint ventures, unless existing written agreements with such a joint venture partner expressly provide for the retention of an alternate manager or otherwise prohibit such retention. In those instances in which either of the Sellers or its Affiliates do not have such controlling interest, each of the Sellers shall use its commercially reasonable efforts to have Purchaser retained, on customary and reasonable terms as agreed to by the Sellers and the Purchaser, as manager in the State of New Jersey.

Section 5.07. Office Leases. Prior to the Closing, the parties shall identify those office leases to which any of the Companies or any Subsidiary is a party, but the office space which is the subject of such lease is being used by an Affiliate of the Sellers which is not one of the Companies or the Subsidiaries (collectively, the “Transferred Leases”). The parties acknowledge and agree that the leases listed in Section 5.07 of the Disclosure Schedule shall be included in the Transferred Leases. Prior to the Closing, the parties shall use all reasonable efforts to make appropriate arrangements for the Affiliates of the Sellers currently using the office space which is the subject of the Transferred Leases to continue be able to use such office space in accordance with the terms of the Transferred Leases following the Closing. Such arrangement may consist of, among other things, an assignment of a Transferred Lease or, if the landlord under such a Transferred Lease refuses to consent to such an assignment, then a sublease of the office space on the same terms as the Transferred Lease.

Section 5.08. Right of First Offer.

(a) If, at any time prior to the fourth anniversary of the Closing (the “Cut Off Date”), an investment opportunity comes to the attention of the Sellers to acquire the real properties located at 500 and 600 Hills Drive, Bedminster, New Jersey (the “ROFO Properties”), the Sellers shall grant to the Purchaser or its designated Affiliate an irrevocable right of first offer to participate in such acquisition on an equal basis with the Sellers.

(b) In such instance, the Sellers shall give written notice (the “ROFO Notice”) to the Purchaser regarding the acquisition opportunity for the ROFO Properties and shall describe all the material business terms of the opportunity. Within thirty (30) calendar days of its receipt of the ROFO Notice, the Purchaser may elect to exercise its right of first offer to participate in the acquisition of the ROFO Properties by delivering to the Sellers its written acceptance of the right of first offer, which acceptance shall set forth its intent to pursue a participation in the acquisition of the ROFO Properties. In the event such written acceptance shall not be received by the Sellers within such ten (10) Business Day acceptance period, to the extent the ROFO Properties remain available for purchase, the Sellers may solicit or offer the participation in the acquisition of the ROFO Properties to a third party, or may otherwise elect to pursue such acquisition without the participation of Purchaser.

(c) The Sellers hereby further agree to use their commercially reasonable efforts to grant to the Purchaser or its designated Affiliate at any time prior to the Cut Off Date, a right of first offer to participate on a pro rata basis with the Sellers or their Affiliates in an investment in such future office development or other purchase opportunities as the Sellers or their Affiliates shall identify from time to time, except in those instances when the Sellers reasonably believe that such an offer would interfere with the Sellers’ institutional relationships.

The parties acknowledge that, notwithstanding the foregoing, the provisions of this Section 5.08 are not intended to, and shall not alter Sellers’ obligations under Section 5.05.

Section 5.09. Use of the Gale Name. After the Closing, neither Sellers nor any of Sellers’ subsidiaries or Affiliates shall use the names or marks “Gale,” “Gale Service Companies,” “Gale Real Estate Services” or any derivative thereof reasonably likely to be confused with the names of Gale Services, Gale Construction or any of the Subsidiaries for commercial purposes. Notwithstanding the foregoing, Sellers shall be permitted to use the names “Gale Investments”, “Gale International”, “The Gale Company” (but only to the extent and in the locations currently used by SG in Asia and without further promoting the use of such name), “Gale Holdings” (outside the Territory only), “Daniel Gale” and names derived from or including such names.

Section 5.10. Stanley C. Gale. For a period of three (3) years after the Closing, SG shall serve as an advisor for the Purchaser’s real property service company on the terms set forth on Exhibit F hereto. Prior to the Closing, SG and the Purchaser hereby agree that they shall negotiate in good faith to enter into a consulting agreement containing the terms set forth on Exhibit F hereto.

Section 5.11. Excluded Assets.

(a) Prior to the Closing, the Sellers shall cause Gale Services to distribute to the Sellers (or an Affiliate of the Sellers other than the Companies and the Subsidiaries) all of the issued and outstanding membership interests of Gale International.

(b) The parties hereby agree that the receivable from Sanofi-Aventis in the amount of approximately $5,400,000 (“Sanofi Receivable”) shall be an Excluded Asset. The Purchaser and MCRLP shall use their commercially reasonable efforts to collect the Sanofi Receivable on behalf of the Sellers and to promptly pay any amounts collected with respect to the Sanofi Receivable to the Sellers promptly following such collection. The Purchaser and MCRLP shall be entitled to deduct from any payment made to the Sellers any commissions payable to employees of the Companies or the Subsidiaries in connection with the Sanofi Receivable.

(c) The parties recognize that certain assets and properties of the Companies and the Subsidiaries, including those listed in Section 1.01(b) of the Disclosure Schedule, are not currently intended to be used in the Business, but, instead, are intended to be retained by the Sellers and their Affiliates following the Closing. The parties further agree that all of such assets and properties are included in the Excluded Assets. In that regard, prior to the Closing and for a period of one (1) year following the Closing, the parties agree to use all reasonable efforts (i) to identify all Excluded Assets held by the Companies and the Subsidiaries and (ii) to cause the Companies and the Subsidiaries to assign, transfer and convey to the Sellers (or Affiliates of the Sellers other than the Companies and the Subsidiaries), without consideration or other payment therefor, all Excluded Assets as they are so identified. To the extent any Excluded Assets were included in the determination of Working Capital on the Closing Statement of Working Capital, the Sellers shall pay to the Purchaser, or the Purchaser shall pay to the Sellers, as the case may be, in consideration therefor, the amount by which the Working Capital was increased or decreased, as the case may be, due to such inclusion of such Excluded Assets in the determination of Working Capital on the Closing Statement of Working Capital.

(d) Furthermore, the parties recognize that certain assets and properties of the Sellers which are intended to be used in the Business may be held by the Sellers or one of their Affiliates. The parties further agree that all of such assets and properties are included in the Assets. In that regard, prior to the Closing and for a period of one (1) year following the Closing, the parties agree (i) to use all reasonable efforts to identify all Assets held by the Sellers or any of their Affiliates and (ii) to cause the Sellers or any of their Affiliates to assign, transfer and convey to the Companies or the Subsidiaries (or Affiliates of the Companies and the Subsidiaries other than the Sellers), without consideration or other payment therefor, all Assets as they are so identified. To the extent any such Assets were excluded in the determination of Working Capital on the Closing Statement of Working Capital, the Sellers shall pay to the Purchaser, or the Purchaser shall pay to the Sellers, as the case may be, in consideration therefor, the amount by which the Working Capital was increased or decreased, as the case may be, due to such exclusion of such Assets in the determination of Working Capital on the Closing Statement of Working Capital.

Section 5.12. Registration Rights.

(a) On or about one (1) year from the Closing Date (the “Filing Date”), MCRLP shall, acting through MCRC, at its expense, register with the SEC on a Registration Statement on Form S-3 (except if MCRC is not then eligible to register for resale the MCRC Common Stock on Form S-3, in which case such registration shall be on another appropriate form in accordance herewith), at its election and in its sole discretion either (i) the initial issuance of shares of MCRC Common Stock into which the O.P. Units may be converted on or after the third anniversary of the Closing Date, as a primary offering on a shelf registration statement pursuant to Rule 415 under the Securities Act, or (ii) the public resale of MCRC Common Stock into which the O.P. Units may be converted on or after the third anniversary of the Closing Date, as a secondary offering on a resale shelf registration statement pursuant to Rule 415 under the Securities Act (the “Registrable Securities”). MCRLP shall, acting through MCRC, cause such Registration Statement to be effective as soon as practicable. If MCRLP elects option (ii), it shall, at its expense, use its best efforts to maintain the effectiveness (the “Effectiveness Time”) of such shelf registration statement until the earlier of (i) such time as when all of the Registrable Securities may be converted have been disposed of or (ii) two (2) years after the redemption of all of the O.P. Units for cash or into MCRC Common Stock. Notwithstanding anything in this Section 5.12 to the contrary, if at the time MCRLP is obligated to file a Registration Statement pursuant to this Section 5.12, MCRLP determines, in the good faith judgment of the Board of Directors of its general partner (MCRC), with the advice of counsel, that the filing of either such shelf registration statement would require the disclosure of non-public material information the disclosure of which would have a material adverse effect on MCRLP, or would otherwise adversely affect a material financing, acquisition, disposition, merger or other significant transaction, MCRLP shall deliver a certificate to such effect signed by the Chief Executive Officer and President of its general partner (MCRC), to the holders of the O.P. Units, and MCRLP may postpone or suspend filing or effectiveness of a registration statement for a period not to exceed forty-five (45) consecutive days, provided that MCRLP may not postpone or suspend its obligation under this Section 5.12 for more than sixty (60) days in the aggregate during any twelve (12) month period; provided, however, that no such postponement or suspension shall be permitted for consecutive sixty (60) day periods, arising out of the same set of facts, circumstances or transactions.

(b) All fees and expenses incident to the performance of or compliance with this Section 5.12 by MCRLP shall be borne by MCRLP whether or not the Registration Statement is filed or becomes effective.

(c) MCRLP shall indemnify and hold harmless each Seller, the officers, directors, agents, brokers (including brokers who offer and sell Registrable Securities as principal as a result of a pledge or any failure to perform under a margin call of MCRC Common Stock), investment advisors and employees of each of them, each Person who controls any such Seller (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, costs of preparation and attorneys’ fees) and expenses (collectively, “Registration Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a

material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading; provided that the foregoing indemnity shall not apply to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding such Seller or such other indemnified party furnished in writing to MCRLP by such Seller expressly for use therein, which information was reasonably relied on by MCRLP for use therein or to the extent that such information relates to such Seller or such Seller’s proposed method of distribution of Registrable Securities. MCRLP shall notify the Sellers promptly of the institution, threat or assertion of any proceeding of which MCRLP is aware in connection with the transactions contemplated by this Agreement.

Section 5.13. Notifications; Update of Disclosure Schedule. Until the Closing, each party hereto shall promptly notify the other party in writing of any fact, change, condition, circumstance or occurrence or nonoccurrence of any event relating to its own representations, warranties or covenants of which it is aware that will or is reasonably likely to result in any of the conditions set forth in Article VII of this Agreement becoming incapable of being satisfied; provided, however, that the delivery of any notice pursuant to this Section 5.13 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice. The Sellers may, from time to time, prior to or at the Closing, by notice given in accordance with this Agreement, supplement or amend the Disclosure Schedule to correct any matter that would otherwise constitute a breach of any representation, warranty, covenant or agreement contained herein. If, pursuant to and in accordance with Section 9.01(d), such a supplement or amendment of any section of the Disclosure Schedule materially and adversely affects the benefits to be obtained by the Purchaser under this Agreement, then the Purchaser shall have the right to terminate this Agreement in accordance with Section 9.01(d), but such termination shall be Purchaser’s sole remedy relating to matters set forth in amendments or supplements to any section of the Disclosure Schedule to the extent such amendment or supplement shall have been delivered on or prior to the Due Diligence Expiration Date. To the extent any such amendment or supplement to any section of the Disclosure Schedule shall be delivered following the Due Diligence Expiration Date, Purchaser shall have the right to terminate this Agreement in accordance with Section 9.01(d), provided, however, Purchaser and MCRLP shall retain any and all rights it would otherwise have under this Agreement, including without limitation Purchaser’s and MCRLP’s rights and remedies under Article VIII.

Section 5.14. Further Action. The parties hereto shall use all reasonable efforts to take, or cause to be taken, all appropriate action, to do or cause to be done all things necessary, proper or advisable under applicable Law, and to execute and deliver such documents and other papers, as may be required to carry out the provisions of this Agreement and consummate and make effective the transactions contemplated by this Agreement in the most expeditious manner practicable.

Section 5.15. Conveyance Taxes. The Purchaser shall be liable for, shall hold the Sellers harmless against, and agrees to pay any and all Conveyance Taxes that may be imposed upon, or payable or collectible or incurred in connection with this Agreement and the transactions contemplated hereby. The Purchaser and the Sellers agree to cooperate in the execution and delivery of all instruments and certificates necessary to enable the Purchaser to comply with any pre-Closing filing requirements.

Section 5.16. Insurance. Sellers hereby covenant and agree to make any claim, on behalf of the Companies and the Subsidiaries, at the request of the Purchaser, for any Loss which is covered by an insurance policy owned by either Seller and not included in the Assets and to use commercially reasonable efforts in the recovery of said insurance proceeds. Furthermore, the Sellers hereby covenant and agree to pay to the Purchaser any insurance proceeds actually recovered from said claims. All rights to uncollected proceeds which vested in the Sellers prior to the Closing Date shall be conveyed, transferred and assigned to the Purchaser in connection with this Agreement, and the Sellers shall waive any and rights or claims with respect to such proceeds.

Section 5.17. Transfer Restrictions. Except as explicitly set forth herein, each Seller agrees that the OP Units issued pursuant to this Agreement may not be Transferred or redeemed for shares of MCRC’s common stock until after the third anniversary of the Closing Date.

Section 5.18. Transition Services. The parties recognize that each of the Purchaser and its Affiliates, on the one hand, and the Sellers and their Affiliates, on the other, will need to provide and receive certain services from the other following the Closing. Prior to the Closing, the parties shall identify all such services to be provided by the Purchaser, the Companies and the Subsidiaries to the Sellers and their Affiliate following the Closing and all such services to be provided by the Sellers and their Affiliates to the Purchaser, the Companies and the Subsidiaries following the Closing. It is agreed by the parties that among the issues addressed will be the extent to which employees and former employees of Gale International and of Gale, Wentworth & Dillon Management Co. will continue to participate and hold account balances in the Gale Company Employee Savings Plan after the Closing, and the extent to which they will cease to so participate and hold such account balances after the Closing. In that regard, at the Closing, the Sellers and the Purchaser shall enter into a transition services agreement, in form and on terms as shall be mutually agreed upon by the parties, with respect to the services contemplated by this Section 5.18.

Section 5.19. Economic Benefits of Assignment. If any note, bond, mortgage or indenture, contract, agreement, lease, sublease, license, permit, franchise, or other instrument or arrangement to which any of the Companies or any Subsidiary is a party set forth on Section 3.04 of the Disclosure Schedule may not be transferred or assigned without the consent, approval or waiver of a third party and the transfer or assignment or attempted transfer or assignment would constitute a breach thereof or a violation of any Law, nothing in this Agreement or in any Ancillary Agreement will be deemed a transfer or assignment or an attempted transfer or assignment thereof. The Sellers will use their commercially reasonable efforts, both before and after the Closing to secure any such consents, approvals or waivers. Without limiting any other provision of this Agreement, if any such consents, approvals and waivers are not (for any reason) obtained before the Closing, then the Sellers will cooperate (at their expense) in any reasonable arrangement requested by the Purchaser and MCRLP to transfer to the Purchaser the economic benefit for all periods after the Closing of any such agreement as to which consent is not obtained, including by enforcement for the benefit of the Purchaser of any and all rights of the Sellers against any other party thereto, and all payments received by the Sellers under any affected agreement for all periods after the Closing will be immediately paid over to the Purchaser. MCRLP and the Purchaser’s consummation of the transactions contemplated in this

Agreement shall not abridge MCRLP’s, the Purchaser’s or the Sellers’ obligations under this Section 5.19, which obligations shall survive the execution and delivery hereof and the Closing, and remain in full force and effect thereafter.

Section 5.20. Delivery of 2004 Pro Forma Financial Statements. The Sellers shall fully cooperate with each other to cause the Companies to deliver to Purchaser not later than five (5) Business Days prior to the Due Diligence Expiration Date, unaudited consolidating pro forma balance sheets and income statements for the Reference Companies as of and for the fiscal year ended as of December 31, 2004 (the “2004 Pro Forma Financial Statements”).

Section 5.21. Preparation of Audited Financials. The Sellers shall cause the Companies to engage an independent accounting firm to commence an audit of the 2005 Financial Statements as soon as reasonably practicable following the date hereof. The parties acknowledge that such audit will, in all likelihood, be completed following the Closing and expressly agree that completion of such audit shall not be a condition to any of the parties’ obligations hereunder. Nevertheless, from the date hereof until the completion of such audit, the Sellers shall provide the auditors with such assistance as may reasonably be requested by them in connection with the preparation of such audit.

Section 5.22. Non-Portfolio Real Property Interests. Prior to the Closing, the parties shall negotiate in good faith, and prepare and enter into an appropriate acquisition agreement or agreements (each, a “Non-Portfolio Real Property Interest Purchase Agreements”) as may be desirable to effect the sale or transfer of the beneficial economic interests of those certain real property interests identified on Exhibit H (each a “Non-Portfolio Interest”) to the Purchaser from the parties identified thereon. Exhibit H also sets forth the amount of consideration to be paid for each Non-Portfolio Interest and (ii) the ownership percentage each Non-Portfolio Interest represents in the real property related thereto. The Non-Portfolio Real Property Interest Purchase Agreements shall (i) contain provisions analogous to Section 5.19 hereof with respect to the Non-Portfolio Interests and (ii) provide that Sellers will be entitled to participate equally with Purchaser in the economic benefit generated by the properties after Purchaser recovers the amount of consideration it paid for such interest plus an agreed upon preferred return. The parties hereto hereby further agree to consummate the transactions contemplated by the Non-Portfolio Real Property Interest Purchase Agreements, on the terms and conditions substantially set forth therein, simultaneously with or prior to the Closing.

Section 5.23. REIT Issues. The Sellers hereby acknowledge the status of MCRC, MCRLP’s general partner, as a real estate investment trust (a “REIT”). The Purchaser and MCRLP intend to operate and manage the Companies and the Subsidiaries in a manner so that: (a) MCRC’s gross income meets the tests provided in Section 856(c)(2) and (3) of the Code; (b) MCRC’s assets meet the tests provided in Section 856(c)(4) of the Code; and (c) MCRC minimizes federal, state, local and excise taxes that may be incurred by MCRC, or any of its Affiliates, including taxes under Sections 857(b), 860(c) or 4981 of the Code. The Sellers shall cooperate with the Purchaser and MCRLP prior to Closing to structure the transactions contemplated by this Agreement in a manner that will enable MCRC to continue to qualify as a REIT on and after the Closing Date. Notwithstanding anything in this Section 5.23 to the contrary, the Sellers shall have no obligation to take any action that would increase a Seller’s liability for Taxes for a Pre-Closing Period or a Pre-Closing Straddle Period.

Section 5.24. Tax Matters.

(a) The Sellers shall be liable for and timely pay any and all Taxes with respect to the ownership or operations of the Companies or the Subsidiaries for all taxable periods ending on or prior to the Closing. Except as otherwise provided herein with respect to Straddle Periods, Purchaser or MCRLP shall be liable for and timely pay any and all Taxes with respect to the ownership or operations of the Companies or the Subsidiaries for all taxable periods ending after the Closing. In any case where applicable law does not permit any Company or any Subsidiary to close its Tax year as of the Closing Date or in any case in which a Tax is assessed with respect to a taxable period which includes the Closing Date (but does not begin or end on that day), then Taxes, if any, attributable to the Tax period of any Company or any Subsidiary beginning before and ending after the Closing Date shall be allocated to and be payable by (i) the Sellers for the period up to and including the Closing Date (the “Pre-Closing Straddle Period”) and (ii) the Purchasers or MCRLP for the period after the Closing Date (the “Post-Closing Straddle Period” and together with a Pre-Closing Straddle Period, a “Straddle Period”). The Sellers shall prepare and timely file all Tax Returns (including applicable filing extensions) for taxable periods ended on or prior to the Closing (a “Pre-Closing Tax Return”); provided, however, that the Sellers shall provide the Purchaser and MCRLP with a copy of any such Pre-Closing Tax Return no later than fifteen (15) calendar days prior to filing such Pre-Closing Tax Return and shall within five (5) calendar days of filing provide the Purchaser and MCRLP with a copy of any such Pre-Closing Tax Return filed with any taxing authority. All Pre-Closing Tax Returns shall be prepared in a manner consistent with the reporting of all items of income or loss on prior Tax Returns of any Company or any Subsidiary, unless otherwise required by applicable laws. The Purchaser or MCRLP shall prepare and shall timely file (including applicable filing extensions) or cause to be prepared and timely filed (including applicable filing extensions) all Tax Returns which begin before the Closing and end after end after the Closing (“Straddle Returns”). Straddle Returns shall be prepared in a manner consistent with the reporting of all items of income and loss on prior Tax Returns of any Company or any Subsidiary, unless otherwise required by applicable laws, and to the extent they involve an allocation of Taxes as to a Pre-Closing Straddle Period shall be subject to Sellers’ approval, which shall not be unreasonably withheld. Taxes payable with Straddle Returns shall be apportioned to the Pre-Closing Straddle Period and Post-Closing Straddle Period, as described above, based on an assumed taxable period ending on the date of Closing; provided, however, that Taxes not based on income or receipts shall be apportioned to the Pre-Closing Straddle Period and Post-Closing Straddle Period based on the number of days in each such taxable period.

(b) If any claim, demand, assessment (including a notice of proposed assessment) or other assertion is made with respect to Taxes against the Sellers or the Purchaser or MCRLP the calculation of which involves a specific matter covered in this Agreement (“Tax Claim”) or if the Purchaser or MCRLP receives any notice from any Governmental Authority with respect to any current or future audit, examination, investigation or other proceeding (“Proceeding”) involving the Sellers, the Purchaser or MCRLP or that otherwise involves a specific matter covered in this Agreement that could directly or indirectly materially affect the Sellers (adversely or otherwise), then the Purchaser or MCRLP, as applicable, shall promptly notify SG (“Sellers’ Representatives”) of such Tax Claim or Proceeding. Any Proceeding that would increase any Seller’s liability for Taxes for a Pre-Closing Period or a Pre-Closing Straddle

Period or could give rise to a claim for indemnification under this Agreement shall be considered material to Sellers.

(c) Sellers shall have the right to control the defense, settlement or compromise of any Proceeding or Tax Claim with respect to the ownership or operations of the Companies or the Subsidiaries for any taxable period ended on or prior to the Closing (“Pre-Closing Period”), unless any such action would reasonably be expected to result in a material adverse Tax effect or a liability or material increase in liability to the Purchaser or MCRLP for any Tax period, in which case, such action may not be taken without Purchaser’s or MCRLP’s consent. The Purchaser or MCRLP shall have the right to control the defense, settlement or compromise of any Proceeding or Tax Claim with respect to the ownership or operations of the Companies or the Subsidiaries for any taxable period ending after the Closing (“Post-Closing Period”), unless any such action would reasonably be expected to result in a material adverse Tax effect or a liability or material increase in liability to Sellers for any Tax period, in which case, such action may not be taken without Seller’s consent. Subject to the provision of this Section 5.24(c), neither Sellers nor the Purchaser or MCRLP shall consent to the entry of any judgment or enter into any settlement with respect to a Tax Claim or Proceeding without the prior written consent of the other party; provided, that each such party shall keep the other party duly and contemporaneously informed of the progress thereof to the extent that such Proceeding or Tax Claim could directly or indirectly materially affect (adversely or otherwise) the other party and shall afford the other party the right to review and comment on any and all submissions made to the IRS or any Governmental Authority with respect to such Tax Claim or Proceeding and shall consider any such comments in good faith. As a condition to withholding its consent to a settlement proposal (i) a party must have a reasonable basis to believe that such settlement would have a material adverse Tax effect or material increase in liability to such party; provided, that if for any period ending after the Closing a proposed settlement does not increase Sellers’ liability for Taxes for a Pre-Closing Period or a Pre-Closing Straddle Period and could not give rise to a claim for indemnification pursuant to this Agreement, then such impact shall not be deemed material to Sellers unless it is different than the impact to other holders of O.P. Units who are not Sellers, and (ii) a party must believe, based on the advice of a nationally recognized accounting or law firm, that it is more likely than not that the position asserted by the party seeking consent would prevail if it were to be asserted in a judicial proceeding. A party withholding its consent shall offer to assume the subsequent costs of defending and asserting the positions asserted by such party, and shall indemnify the other party for any taxes and related interest and penalties resulting from a subsequent judgment in excess of the amounts that would have been imposed pursuant to the rejected settlement (but not any other costs associated with such proceeding or any other issues involved therein).

(d) From and after the Closing, the parties shall provide each other with such assistance as may reasonably be requested by any of them in connection with (i) the preparation of any Tax Return, election, consent or certificate required to be prepared by any party hereto or (ii) any Tax Claim or Proceeding. Such assistance shall include making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder and shall include providing copies of any relevant Tax Returns and supporting work schedules.

(e) The Sellers and the Purchaser shall discuss and consult, in an attempt to reach agreement, an allocation of the purchase price (as determined for federal income tax purposes) among the assets of the Companies (the “Allocation”). If the parties cannot agree, then notwithstanding anything in 5.24(c) to the contrary, any Tax Claim or Proceeding involving the Allocation shall be under the exclusive control of the party against whom the Tax Claim is made and such party shall be free to pursue and/or settle such Tax Claim without the approval of the other party.

Article VI

EMPLOYEE MATTERS

Section 6.01. Employee Benefits. As of the Closing Date, the Purchaser shall (and MCRLP shall cause the Purchaser to) cause the Companies and the Subsidiaries to continue to employ all employees of Gale Services, Gale Construction and the Subsidiaries (the “Company Employees”), with the understanding that such employment shall be on the same terms as the Company Employees are currently employed. With respect to such Company Employees, the Purchaser (or Gale Services, Gale Construction or the Subsidiaries) shall (a) for a period of one (1) year following the Closing, cause any Company Employee that was covered under a medical or dental plan, disability benefit plan, 401(k) plan or life insurance plan (collectively, the “Benefit Plans”) of Gale Services, Gale Construction or any Subsidiary immediately prior to the Closing Date to receive coverage on the Closing Date that is comparable in the aggregate to such coverage provided to the Company Employees by the Company immediately prior to the Closing Date subject to any applicable limitations arising from the nondiscrimination requirements of the Code, (b) recognize the service completed by the Company Employees for purposes of determining eligibility service and vesting service under any employee benefit plan, program or arrangement maintained by the Purchaser (or the Companies or any Subsidiary) for their employees on or after the Closing Date to the same extent such service was credited under any employee benefit plan, program or arrangement provided by the Companies or any Subsidiary immediately prior to the Closing Date; provided, that the foregoing shall not be construed to require crediting of service that would result in violation of the nondiscrimination requirements of the Code, duplication of benefits, service credit for benefit accruals, service credit under a newly established plan for which prior service is not taken into account, or employer contribution for any 401(k) plan, (c) cause to be waived any pre-existing condition limitations under welfare benefit plans of the Purchaser or its Affiliates in which the Company Employees participate (to the extent those conditions were waived under the corresponding Plans of the Companies or any Subsidiary), (d) cause to be credited any co-payments, deductibles and out-of-pocket requirements incurred by the Company Employees and their beneficiaries and dependents during the portion of the calendar year prior to participation in the benefit plans provided by the Purchaser, and (e) assume responsibility for the earned wages, compensation levels, vacation time, bonuses (including stay or success bonuses) that are accrued on the Closing Statement of Working Capital, commissions, and sick leave benefits due to the Company Employees as of the Closing Date.

Section 6.02. Former AT&T Employee Severance Obligations. After the Closing, if the Purchaser, Gale Services, Gale Construction or any of the Subsidiaries terminates the employment of any of the employees listed in Section 6.02 of the Disclosure Schedule (the

“Former AT&T Employees”), the Sellers shall reimburse the Purchaser for any amounts that shall be due and payable by the Purchaser, the Companies or any Subsidiary to such Former AT&T Employees pursuant to the AT&T Agreement, less any amounts required to be reimbursed by AT&T pursuant to the terms of the AT&T Agreement. Notwithstanding the foregoing, in no event shall Sellers reimburse the Purchaser for any such amounts which may be due and payable to such Former AT&T Employees if the AT&T Agreement shall, after the Closing, have (i) expired in accordance with its terms or (ii) been amended, modified or extended in a manner that adversely affects the payments required to be made by the Company or any Subsidiary thereunder.

Article VII

All covenants and agreements contained herein shall remain in full force and effect for a period of eighteen (18) months following the Closing, except for those covenants and agreements that by their terms are to be performed in whole or in part after the Closing, which shall remain in full force and effect for a period equal to the later of eighteen (18) months after the Closing or eighteen (18) months following the date by which such covenant or agreement is required to be performed; provided, however, that any claim made with reasonable specificity by the party seeking to be indemnified within the time periods set forth in this Section 8.01 shall survive until such claim is finally and fully resolved.

Section 8.02. Indemnification by the Sellers. Subject to Section 8.07, MCRLP the Purchaser and their Affiliates, officers, directors, employees, agents, successors and assigns (each, a “Purchaser Indemnified Party”) shall be indemnified and held harmless by the Sellers, jointly and severally, for and against all losses, damages, claims, costs and expenses, interest, awards, judgments and penalties (including reasonable attorneys’ and consultants’ fees and expenses) actually suffered or incurred by them (hereinafter, a “Loss” or, collectively “Losses”), arising out of or resulting from: (a) the breach of any representation or warranty made by the Sellers contained in this Agreement, (b) the breach of any covenant or agreement by the Sellers contained in this Agreement, (c) any of the Sellers (or any predecessor of any of the Sellers) having been a member of an “affiliated group” (as defined in Section 1504(a) of the Code) for any consolidated, combined or unitary foreign, state or local tax purposes, (d) any Tax sharing, allocation or similar agreement to which the Companies and the Subsidiaries are a party prior to or as of the Closing, (e) all Taxes attributable to the activities of Gale Services, Gale Construction or any Subsidiary attributable to the period on or prior to the Closing except as set forth as a reserve or liability on the Final Financial Statements or (f) the Excluded Assets (including the employment agreements identified on Section 1.01(b) of the Disclosure Schedule).

Section 8.03. Indemnification by the Purchaser. The Sellers and their Affiliates, officers, directors, employees, agents, successors and assigns (each, a “Seller Indemnified

Party”) shall be indemnified and held harmless by MCRLP and the Purchaser, jointly and severally, for and against any and all Losses, arising out of or resulting from: (a) the breach of any representation or warranty made by the Purchaser or MCRLP contained in this Agreement, (b) the breach of any covenant or agreement by the Purchaser or MCRLP contained in this Agreement, or (c) any Liability of Gale Services, Gale Construction or any Subsidiary arising before or after the Closing, except to the extent the Sellers are obligated to indemnify the Purchaser Indemnified Parties pursuant to Section 8.02.

Section 8.04. Limits on Indemnification.

(a) No claim may be asserted nor may any Action be commenced against either party for breach of any representation, warranty, covenant or agreement contained herein, unless written notice of such claim or action is received by such party describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or Action on or prior to the date on which the representation, warranty, covenant or agreement on which such claim or Action is based ceases to survive as set forth in Section 8.01, irrespective of whether the subject matter of such claim or action shall have occurred before or after such date.

(b) Notwithstanding anything to the contrary contained in this Agreement: (i) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to Sections 8.02(a) (other than with respect to the representation and warranty set forth in Section 3.14(i)) or 8.03(a), unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds $250,000 (the “Indemnification Threshold”) after which the Indemnifying Party shall fully indemnify the other party for the total of such Losses; (ii) the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 8.02(a) (other than with respect to the representation and warranty set forth in Section 3.14(i)) or 8.03(a) shall be an amount equal to $4,000,000, (iii) neither party hereto shall have any liability under any provision of this Agreement or the Ancillary Agreements for any punitive damages, and (iv) the Sellers shall have no obligation to indemnify any Purchaser Indemnified Party for any breach of the Sellers representations, warranties, covenants or agreements contained herein which is corrected pursuant to an amendment or supplement to the Disclosure Schedule made prior to the Due Diligence Expiration Date pursuant to Section 5.13.

(c) For all purposes of this Article VIII, “Losses” shall be net of any insurance or other recoveries actually received by the Indemnified Party or its Affiliates in connection with the facts giving rise to the right of indemnification.

Section 8.05. Notice of Loss; Third Party Claims.

(a) An Indemnified Party shall give the Indemnifying Party notice of any matter which an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within sixty (60) days of such determination, stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises.

(b) If an Indemnified Party shall receive notice of any Action, audit, claim, demand or assessment (each, a “Third Party Claim”) against it which may give rise to a claim for Loss under this Article VIII, within thirty (30) days of the receipt of such notice, the Indemnified Party shall give the Indemnifying Party notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article VIII except to the extent that such failure results in a detriment to the Indemnifying Party and shall not relieve the Indemnifying Party from any other Liability that it may have to any Indemnified Party other than under this Article VIII. The Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if it gives notice of its intention to do so to the Indemnified Party within fifteen (15) days of the receipt of such notice from the Indemnified Party. If the Indemnifying Party elects to undertake any such defense against a Third Party Claim, the Indemnified Party may participate in such defense at its own expense. The Indemnified Party shall fully cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. If the Indemnifying Party elects to direct the defense of any such claim or proceeding, the Indemnified Party shall not pay, or permit to be paid, any part of such Third Party Claim unless the Indemnifying Party consents in writing to such payment or unless the Indemnifying Party withdraws from the defense of such Third Party Claim liability or unless a final judgment from which no appeal may be taken by or on behalf of the Indemnifying Party is entered against the Indemnified Party for such Third Party Claim. If the Indemnifying Party assumes the defense of any such claims or proceeding pursuant to this Section 8.05 and proposes to settle such claims or proceeding prior to a final judgment thereon or to forgo any appeal with respect thereto, then the Indemnifying Party shall give the Indemnified Party prompt written notice thereof and the Indemnified Party shall have the right to participate in the settlement or assume or reassume the defense of such claims or proceeding. The Indemnifying Party shall not enter into any settlement or compromise of any action, suit or proceeding or consent to the entry of any judgment (i) which does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a written release from all liability in respect of such action, suit or proceeding or (ii) for other than monetary damages to be borne in full by the Indemnifying Party without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 8.06. Remedies. MCRLP, the Purchaser and each of the Sellers acknowledge and agree that (i) following the Closing, the indemnification provisions of Section 8.02 and Section 8.03 shall be the sole and exclusive remedies of the parties for any breach by the other party of the representations and warranties in this Agreement and for any failure by the other party to perform and comply with any covenants and agreements contained in this Agreement, except that if any of the provisions of this Agreement are not performed in accordance with their terms or are otherwise breached, the parties shall be entitled to specific performance of the terms thereof in addition to any other remedy at Law or equity and (ii) anything herein to the contrary notwithstanding, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of MCRLP, the Purchaser or the Sellers, after the consummation of the purchase and sale of the Membership Interests contemplated by this Agreement, to rescind this Agreement or any of the transactions

contemplated hereby. Each party hereto shall take all reasonable steps to mitigate its Losses upon and after becoming aware of any event which could reasonably be expected to give rise to any Losses. The Purchaser shall only have the right to set off any Losses for which the Purchaser Indemnified Parties are entitled to indemnification pursuant to Section 8.02(a) from any payment required to be made to the Sellers pursuant to the Earnout. Notwithstanding the foregoing and after no additional Earnout payments are capable of being earned, if any Losses, or any portion thereof, for which the Purchaser Indemnified Parties are entitled to indemnification pursuant to Section 8.02(a) were not satisfied by set off from the Earnout, the Sellers may elect, at their sole option, to satisfy their obligations for such Losses by either (i) paying any such obligations in cash, or (ii) instructing Purchaser or MCRLP to cancel such number of O.P. Units held in the name of the Indemnifying Party as shall be equal to (x) the aggregate dollar value of the Loss not otherwise set off from the Earnout divided by (y) $44.50 (or any combination of clauses (i) and (ii)).

Article IX

Section 9.01. Termination. This Agreement may be terminated at any time prior to the Closing:

(a) by either the Sellers, or the Purchaser, if the Closing shall not have occurred by the termination date specified in the Real Estate Agreement (including any extension thereof); provided, however, that the right to terminate this Agreement under this Section 9.01(a) shall not be available to any party whose failure to fulfill any obligation under this Agreement shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to such date;

(e) by the Sellers, if MCRLP or the Purchaser shall have breached any of its representations, warranties, covenants or agreements contained in this Agreement which would give rise to the failure of a condition set forth in Article VII, which breach cannot be or has not

been cured within thirty (30) days after the giving of written notice by the Sellers to the Purchaser specifying such breach;

(f) by the Purchaser, if the Sellers shall have breached any of their representations, warranties, covenants or agreements contained in this Agreement which would give rise to the failure of a condition set forth in Article VII, which breach cannot be or has not been cured within thirty (30) days after the giving of written notice by the Purchaser to the Sellers specifying such breach; or

(g) by the mutual written consent of the Sellers and the Purchaser.

Notwithstanding anything contained herein to the contrary, if the parties to the Real Estate Agreement shall consummate the transactions contemplated by the Real Estate Agreement, unless this Agreement shall have been terminated prior to such consummation pursuant to this Article IX, neither MCRLP nor the Purchaser shall have any right to terminate this Agreement.

Section 10.03. Public Announcements; Confidentiality. Upon the execution of this Agreement, the Purchaser and MCRLP shall have the right to make such public announcements or filings as may be required by (i) the Securities Act, (ii) the Securities Exchange Act, (iii) the rules and listing standards of the New York Stock Exchange, Inc., (iv) any other law of a jurisdiction to which MCRLP is subject, or (v) any oral questions, interrogatories, requests for information, subpoena, civil investigative demand, or similar process required by applicable rules, laws or regulations by any court, law or administrative authority to which Purchaser and MCRLP are subject. Purchaser and MCRLP also shall have the right to make such public announcements or filings as they may deem reasonably prudent, and shall be entitled to make such filings or announcements upon advice of counsel as may be otherwise be deemed necessary. In this connection, it should be noted that MCRLP has determined that the entry into this Agreement will need to be disclosed within four (4) business days of its execution on a Current Report on Form 8-K under Item 1.01 thereof and that the Agreement will be filed as an exhibit thereto or be filed as an exhibit to MCRLP’s next following periodic report filed pursuant to the Securities Exchange Act. Sellers may make such public disclosures as are required by Law. Each of Sellers, Purchaser and MCRLP hereby agree to provide the non-disclosing parties as much advance notice as reasonably possible with respect to the nature of such disclosure, cooperate fully as to the timing and contents of such disclosure and review in good faith the suggestions of the other party with respect to the contents of such disclosure.

Section 10.04. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to either party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible.

Section 10.05. Entire Agreement. This Agreement (including the Exhibits and the Disclosure Schedule) and the Ancillary Agreements constitute the entire agreement of the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, between the Sellers and the Purchaser with respect to the subject matter hereof and thereof.

Section 10.06. Assignment. This Agreement may not be assigned by operation of Law or otherwise without the prior express written consent of the Sellers, and the Purchaser or

MCRLP which consent may be granted, conditioned, delayed or withheld in the sole discretion of the Sellers or the Purchaser or MCRLP, as the case may be. Notwithstanding the foregoing, the Purchaser may assign any or all of its interests in this transaction to one or more Affiliates, provided, that any such assignment shall not relieve the Purchaser from its obligations hereunder.

Section 10.07. Amendment. This Agreement may not be amended or modified except (a) by an instrument in writing signed by, or on behalf of, the Sellers and the Purchaser or MCRLP or (b) by a waiver in accordance with Section 10.08.

Section 10.08. Waiver. Any party to this Agreement may (a) extend the time for the performance of any of the obligations or other acts of the other party, (b) waive any inaccuracies in the representations and warranties of the other party contained herein or in any document delivered by the other party pursuant hereto, or (c) waive compliance with any of the agreements of the other party or conditions to such party’s obligations contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party to be bound thereby. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of either party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights.

Section 10.09. No Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied (including the provisions of Article VI relating to employee matters and Article VIII relating to indemnified parties), is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement.

Section 10.10. Currency. Unless otherwise specified in this Agreement, all references to currency, monetary values and dollars set forth herein shall mean United States (U.S.) dollars and all payments hereunder shall be made in United States dollars.

Section 10.11. Governing Law. This Agreement and all others arising out of or relating to this Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware.

NOI shall be determined without duplication.

Notwithstanding anything else to the contrary contained in this Agreement, NOI is intended to be calculated in accordance with the manner in which the original pro-forma income statement (which was prepared by the Sellers and provided to MCRLP and the Purchaser as part of their initial evaluation of the Companies and that formed the basis for the Modeled NOI that was the basis of the earnout calculations contained in this Exhibit D) was prepared.

Section 3.02 Determination of Earnout Payments. (a) In addition to, and along with, delivering the Certified Balance Sheets and Income Statements for the prior Anniversary Year, the Purchaser shall prepare and deliver to the Sellers a statement which sets forth, in reasonable detail, the Purchaser’s determination of the payment due to the Sellers under Sections 2.02, 2.03 or 2.04, as the case may be (an “Earnout Payment”), if any, payable in respect of the prior Anniversary Year. In accordance with Section 3.01(b) above, at all reasonable times during the thirty (30) days immediately following the Seller’ receipt of such statement, the Sellers and the Sellers’ accountants (“Sellers’ Accountants”) shall be permitted to review the Purchaser’s and Purchaser’s accountants (“Purchaser’s Accountants”) financial information and working papers relating to the Certified Balance Sheets and Income Statements and the Purchaser shall make

D-7

available to the Sellers and the Sellers’ Accountants at reasonable times and on reasonable advance notice the individuals responsible for the preparation of the Certified Balance Sheets and Income Statements in order to respond to the reasonable inquiries of the Sellers and the Sellers Accountants.

(b) The Sellers shall notify the Purchaser in writing within thirty (30) days after receiving each of the statements of determination for each Anniversary Year if the Sellers and the Sellers’ Accountants disagree with any amounts reflected on such statement of determination. The notice of disagreement shall set forth in reasonable detail the reason for such dispute, the dollar amounts involved and the Sellers and Sellers’ Accountants good faith estimate of the applicable Earnout Payment. If the Sellers and the Sellers’ Accountants do not deliver a notice of disagreement to the Purchaser within such thirty (30)-day period, then the Purchaser’s statement of determination shall be deemed to have been accepted by the Sellers and the Sellers’ Accountants and upon the expiration of such thirty (30)-day period shall become final and binding. If the Sellers do deliver a notice of disagreement, only those matters specified in reasonable detail in such notice of disagreement shall be deemed to be in dispute, and all other matters shall be final and binding.

(c) During the thirty (30) days immediately following the delivery of a notice of disagreement, the Sellers and the Sellers’ Accountants and the Purchaser and the Purchaser’s Accountants, in good faith, shall seek to resolve any differences that they may have with respect to any matter specified in such notice of disagreement, and any resolution by them as to any such matter shall be final and binding. If at the end of such thirty (30)-day period, the Sellers and the Sellers’ Accountants and the Purchaser and the Purchaser’s Accountants have been unable to agree upon all matters specified in such notice of disagreement, then the Sellers and the Sellers’ Accountants and the Purchaser and the Purchaser’s Accountants shall submit to an Independent Accounting Firm for review and resolution any and all matters specified in the notice of disagreement that remain in dispute. The Purchaser and the Sellers shall cause the Independent Accounting Firm to make a final determination (which determination shall be binding on the parties hereto) of the Earnout Payment for the applicable Anniversary Year within thirty (30) days from such submission. The cost of the Independent Accounting Firm’s review and determination shall be shared equally by the Sellers and the Purchaser. During such thirty (30)-day review, the Purchaser and the Sellers shall each make available to the Independent Accounting Firm such individuals and such information, books and records as may be reasonably required by the Independent Accounting Firm to make its final determination.

Section 4 Characterization of Earnout Payments. All amounts paid by the Purchaser with respect to Earnout pursuant to the Agreement shall, to the extent permitted by applicable Law, be treated as adjustments to the Purchase Price for all Tax purposes. Each of the Purchaser and the Sellers agree to report, on their respective Tax Returns, the allocation of any Earnout consistently (including any adjustment to an Earnout pursuant to this Exhibit D).

Section 5 Covenants of MCRLP and the Purchaser Relating to the Conduct of Business. Each of MCRLP and the Purchaser acknowledges that a significant portion of the consideration for the Companies and the Subsidiaries hereunder is to be satisfied by the AT&T Earnout Payment and the Earnout Payments described in this Exhibit D. Accordingly, each of MCRLP and the Purchaser, on the one hand, and the Sellers, on the other hand, covenant and

D-8

agree to act in good faith to work with the others to prepare and implement a Budget and Operating Plan for the Companies and the Subsidiaries for each Anniversary Year (or, if agreed to by the Purchaser and the Sellers, fiscal year) which shall set forth the manner in which the Business of the Companies and the Subsidiaries is to be conducted. Each of MCRLP and the Purchaser further covenants and agrees to manage the Companies and the Subsidiaries from the Closing Date through the end of the Third Anniversary Year as a prudent owner would manage the Companies and the Subsidiaries and to use its commercially reasonable efforts to manage the Companies and the Subsidiaries in a manner substantially as previously managed and in accordance with the Budget and Operating Plan, subject to its overriding fiduciary duties to all of its and MCRC’s equity owners.

MCRLP and the Purchaser hereby agree that they shall procure that MCRC (or any of its Affiliates) shall not, and not cause the Purchaser, the Company or any of the Subsidiaries to, terminate or adversely amend, any property management, facilities management, leasing, construction management or real estate brokerage agreement or arrangement with respect to any property currently managed by the Company and the Subsidiaries, absent a material breach of such agreement or arrangement, other than an action taken in good faith in response to an action initiated by the other party to such agreement or arrangement. If MCRC or any of its Affiliates shall, or shall cause the Purchaser, the Company or any of the Subsidiaries to, terminate or adversely amend any such agreement or arrangement, MCRLP and the Purchaser agree that any income and corresponding expense that would have been derived under any such agreement or arrangement prior to such amendment or termination shall be included in the Purchaser’s calculation of Gross Income and NOI as if such contract or arrangement were not so terminated or adversely amended. The Sellers, MCRLP and the Purchaser also agree that the schedule of management fees with respect to the Class B Properties (as defined in the Real Estate Agreement) which are to be acquired as part of the Real Estate Agreement specified in the related Amended and Restated Limited Liability Company Agreement of Mack-Green-Gale LLC to be entered into upon the consummation of the transactions contemplated by the Real Estate Agreement shall not constitute such an adverse amendment or arrangement.

Furthermore, but subject to the fiduciary duty the Purchaser owes to its and MCRC’s equity owners, each of MCRLP and the Purchaser hereby covenants and agrees that from the Closing Date through the end of the Third Anniversary Year it shall cause the Companies and their Subsidiaries:

(i) to continue to solicit new clients and to service its existing and new clients substantially in accordance with its long-standing service expertise and practices, provided that the foregoing shall not prevent the Purchaser from consolidating operations, taking actions intended to permit the Purchaser to operate the Companies and the Subsidiaries in a more efficient manner or taking actions intended to facilitate its tax requirements, including MCRC’s status as a REIT;

(ii) to continue to operate the Companies and the Subsidiaries as a separate and distinct division, with a separate set of financial records, and not to permit the Business to be discontinued, dissolved, transferred to a non-affiliated third party or otherwise sold (through a sale of stock, sale of assets, operation of merger or otherwise), unless the acquiring party expressly agrees to be bound by the provisions of this Exhibit D;

D-9

(iii) to maintain records to allow for the calculations of AT&T Gross Income, Gross Income and NOI that shall be complete and accurate in all material respects, including, without limitation, not changing the accounting principles, practices, policies and methodologies of the Companies or the Subsidiaries for the Business for the purpose of the calculation of AT&T Gross Income, Gross Income and NOI; and

(iv) not to take any action or omit to take any action in connection with the operation of the Business which would, or would reasonably be likely to, reduce the amount of AT&T Gross Income, Gross Income and/or NOI or the ability of the Seller to achieve the AT&T Earnout Payment or any Earnout Payment.

Notwithstanding anything contained herein to the contrary, the Purchaser shall be entitled to take any action or omit to take any action in connection with the operation of the Business which would, or would reasonably be likely to, reduce the amount of AT&T Gross Income, Gross Income and/or NOI or the ability of the Seller to achieve the AT&T Earnout Payment or any Earnout Payment so long as (i) such action or omission is in the ordinary course of the Business and consistent with the Budget and Operating Plan and the primary purpose of such action or omission is not to reduce AT&T Gross Income, Gross Income or NOI or the ability of the Seller to achieve the AT&T Earnout Payment or any Earnout Payment or (ii) if after such action or omission is taken, the Purchaser shall promptly deliver to the Sellers a written proposal to adjust the calculation of Gross Income and NOI, so that achieving the AT&T Earnout Payment or each Earnout Payment will not be less likely due to such action or omission (an “Adjustment Proposal”).

If the Purchaser shall deliver to the Sellers an Adjustment Proposal, the Sellers shall, within thirty (30) days after receiving an Adjustment Proposal, either (i) deliver a written notice to the Purchaser agreeing to such Adjustment Proposal (an “Acceptance Notice”) or (ii) deliver a written notice to the Purchaser that the Sellers object to the Adjustment Proposal (an “Objection Notice”). If the Sellers deliver an Acceptance Notice or fail to deliver a timely Objection Notice, then the Adjustment Proposal shall be deemed to be accepted by the Sellers and final, binding and conclusive upon the Purchaser and the Sellers. If the Sellers shall timely deliver an Objection Notice, then the Purchaser and the Sellers shall negotiate, in good faith, for a period of thirty (30) days (the “Negotiation Period”), an adjustment to the calculation of Gross Income and/or NOI, as necessary, so that achieving the AT&T Earnout Payment or each Earnout Payment will not be less likely due to such action or omission. Any resolution reached by the Sellers and the Purchaser shall be final, binding and conclusive upon the Sellers and the Purchaser.

If the Negotiation Period shall have expired without the full resolution of all matters regarding the Adjustment Proposal, then the parties shall submit all unresolved issues for resolution to an Independent Accounting Firm, which shall, within thirty (30) days after such submission, determine and report to the Sellers and the Purchaser upon such remaining disputed items, and such report shall be final, binding and conclusive on the Sellers and the Purchaser. The fees and disbursements of the Independent Accounting Firm’s review and determination shall be shared equally by the Sellers and the Purchaser.
