From and after such resignation and the delivery of the Deposit and Interest accrued thereon to such successor escrow agent, the Escrow Agent shall be fully relieved of all of its duties, responsibilities and obligations under this Agreement, all of which duties, responsibilities and obligations shall be performed by the appointed successor escrow agent. If for any reason the parties hereto shall not approve a successor escrow agent within such period, the Escrow Agent may bring any appropriate action or proceeding for leave to deposit the Deposit and Interest accrued thereon with a court of competent jurisdiction, pending the approval of a successor escrow agent, and upon such deposit the Escrow Agent shall be fully relieved of all of its duties, responsibilities and obligations under this Agreement, provided, that the Escrow Agent shall continue to act as escrow agent hereunder and hold the Deposit and Interest in escrow in accordance with the terms and conditions contained herein until the parties shall approve a successor escrow agent in writing or the Deposit and Interest is deposited with a court of competent jurisdiction in accordance with the terms hereof.

(14) Seller and Purchaser hereby agree to, jointly and severally, indemnify, defend and hold the Escrow Agent harmless from and against any liabilities, damages, losses, costs or expenses incurred by, or claims or charges made against, the Escrow Agent (including reasonable attorneys’ fees, expenses and court costs) by reason of the Escrow Agent’s acting or failing to act in connection with any of the matters contemplated by this Agreement or in carrying out the terms of this Agreement, except as a result of the Escrow Agent’s gross negligence or willful misconduct.

(16) The Escrow Agent shall invest the Deposit in the investments described in Schedule 3.3(j) attached hereto (“Permitted Investments”).

In the event any such notice of disagreement is timely provided, Purchaser and Seller, in conjunction with their respective independent accounting firms, shall use reasonable best efforts for a period of ten (10) Business Days (or such longer period as they may mutually agree) to resolve any disagreements with respect to the calculation of Closing Date Working Capital. If, at the end of such period, they are unable to resolve such disagreements, then Seller and Purchaser agree that Ernst & Young LLP (the “Auditor”) shall be empowered to resolve any remaining disagreements. Purchaser and Seller agree to use commercially reasonable efforts to cause the Auditor to determine as promptly as practicable whether the Closing Balance Sheet was prepared in accordance with the standards set forth in this Agreement and, only with respect to the disagreements submitted to the Auditor, whether and to what extent (if any) Closing Date Working Capital requires adjustment.

The fees and expenses of the Auditor shall be paid one-half by Purchaser and one-half by Seller. The determination of the Auditor shall be final, binding and conclusive for purposes of this Agreement and not subject to any further recourse by Purchaser or Seller under any provision hereof. The date on which Closing Date Working Capital is finally determined in accordance with this Section 4.3(c) is hereinafter referred to as the “Determination Date.”

-16-

equal to 45% of the amount by which Closing Date Working Capital, as finally determined, exceeds the Pre-Closing Working Capital. Subject to subsections (e) and (f) below, in the event that the Pre-Closing Working Capital exceeds the Closing Date Working Capital, as finally determined pursuant to Section 4.3(c) above, then Seller shall pay to Purchaser an amount equal to 45% of the amount by which the Pre-Closing Working Capital exceeds the Closing Date Working Capital, as finally determined. All payments under this subsection (d) shall be made within seven (7) Business Days of the Determination Date and shall be paid in cash by wire transfer of immediately available funds.

(24) Legal fees incurred on or prior to the Closing Date, and fees payable by the Company to Ernst & Young in connection with the E&P Dividend and the examination of the REIT consequences of certain relationships between the Company and RGI and certain parties related to RGI, that are chargeable to the Company on account of the transactions contemplated by this Agreement, whether billed to the Company or charged through to the Company by RGI, and which fees are presently estimated to be $350,000, shall be: (i) excluded from Current Liabilities for all purposes of Section 4.3 (except as provided in subparagraph (ii) hereof) and (ii) shall be included in Current Liabilities for purposes of Closing Date Working Capital under Section 4.3(d) hereof.

Except as provided herein, Income Taxes Payable shall not be included in the Working Capital adjustment provided for in Section 4.3 hereof.

(1) From and after the Closing Date, and subject to Sections 7.1(c) and 7.6 hereof, Seller agrees to indemnify, protect, defend and hold harmless the Purchaser and each principal, partner, member, director, officer, employee, stockholder, agent and other representative of any of them (a “Purchaser Indemnified Party”), from and against any and all losses, liabilities, suits, damages, expense and claims (whether direct or indirect) asserted against, imposed upon or incurred by any such Purchaser Indemnified Party by reason of or resulting from (a) any representation or warranty by the Seller or fact set forth in any representation of Seller, any of the Schedules relating to this Agreement or any other Closing certificate or Closing document delivered by Seller pursuant to this Agreement (including the Manager’s Certificate) not having been true and correct on the date hereof and as of the Closing (without giving effect to any qualifications or exceptions relating to the knowledge of the Seller contained in clause (C) of Section 5.2, Section 5.3(a) or (b), Section 5.6, Section 5.10, Section 5.11, Section 5.21, Section 5.23, and Section 5.24) or (b) the breach by Seller of any covenant or obligation of Seller in this Agreement, including, without limitation, Seller’s obligation to pay any taxes required to be paid by Seller under Section 4.4 hereof.

(2) From and after the Closing Date, and subject to Section 7.1(c) hereof, Purchaser shall indemnify and hold harmless the Seller, any Affiliate of the Seller and any principal, partner, member, director, officer, employee, agent or other representative of any of them (a “Seller Indemnified Party”), from and against any and all losses actually incurred by any such Seller Indemnified Party by reason of or resulting from (a) the breach of any representation or warranty by the Purchaser or any Closing certificate or Closing document delivered by Purchaser pursuant to this Agreement or (b) the breach by Purchaser of any covenant or obligation of Purchaser in this Agreement.

(3) All representations and warranties of the Seller contained herein or made pursuant hereto are given and shall survive until the date that is twelve (12) calendar months after the Closing Date except as set forth below; provided, however, that all representations and warranties of the Seller set forth in Sections 5.10, 5.11 and/or 5.13 and all of Article XIV shall survive the Closing until the expiration of the applicable statute of limitations. The date on which a given representation or

-28-

warranty expires is referred to as the “Purchaser Warranty Claim Termination Date” with respect to such representation or warranty. The representations and warranties of the Purchaser contained herein or made pursuant hereto shall survive until the date that is twelve (12) calendar months after the Closing Date (such relevant date being hereinafter referred to as the “Seller Warranty Claim Termination Date”).

Section VII.2 Warranty Claims. Subject to Section 7.1(c), any claim by either the Seller or the Purchaser pursuant to Section 7.1 with respect to a claimed breach by the other party of a representation or warranty (a “Warranty Claim”) shall expire, if applicable, at the relevant Purchaser Warranty Claim Termination Date or the Seller Warranty Claim Termination Date, as applicable, except with respect to Warranty Claims with respect to which the party making any such claim hereunder has delivered written notice of such claim to the other party. If any written notice of claim has been given by the Purchaser to the Seller prior to the relevant Warranty Claim Termination Date or by the Seller prior to the relevant Warranty Claim Termination Date, then the relevant representations, warranties and indemnities shall survive the relevant Purchaser Warranty Claim Termination Date or the Seller Warranty Claim Termination Date, as applicable, as to (but only as to) such Warranty Claim, until such Warranty Claim has been finally resolved, it being understood that the Purchaser or the Seller, as applicable, may update or amend the Warranty Claim to include facts and circumstances that relate to such claim but are only later discovered or quantified, but may not assert any new or additional claims. No Warranty Claim may be brought by the Purchaser or the Seller if and to the extent that the matters giving rise to the Warranty Claim were expressly disclosed in this Agreement.

Section VII.3 Indemnification Procedure.

(4) As a condition to the indemnity obligations hereunder, the party seeking indemnification shall notify the other party obligated to provide indemnification (the “Indemnifying Party”) promptly after it obtains actual knowledge of the claims, events or circumstances giving rise to its seeking indemnification. If such event involves any claim or the commencement of any action or proceeding by a third person, the party seeking indemnification will give such Indemnifying Party written notice of such claim or the commencement of such action or proceeding. Such notice shall be a condition precedent to any liability of the Indemnifying Party hereunder. Such Indemnifying Party shall have a period of thirty (30) days within which to respond thereto. If such Indemnifying Party accepts responsibility or does not respond within such thirty (30) day period, such Indemnifying Party shall be obligated to defend such claim, action or proceeding, at its own expense and by counsel chosen by the

-29-

Indemnifying Party and reasonably satisfactory to the party seeking indemnification. If such Indemnifying Party does respond within such thirty (30) day period and rejects its indemnification obligation for such matter, in whole or in part, or does not respond and does not comply with its obligations under the preceding sentence, the party seeking indemnification shall be free to pursue, without prejudice to any of its rights hereunder, such claims, rights, defenses and remedies as may be available to such party under applicable law. If the Indemnifying Party has assumed its indemnification obligation, (i) the party seeking indemnification agrees to cooperate fully with the Indemnifying Party and its counsel in the defense against any such asserted liability and shall have the right to participate at its own expense in the defense of such asserted liability and (ii) any compromise of such asserted liability by the Indemnifying Party shall require the prior written consent of the party seeking indemnification unless such compromise includes a general release from liability in favor of the party seeking indemnification with respect to the matters which are the subject of such compromise; provided, however, that if the party seeking indemnification unreasonably refuses its consent to a bona fide offer of settlement which the Indemnifying Party wishes to accept, the party seeking indemnification may continue to pursue such matter, free of any participation by the Indemnifying Party, at the sole expense of the party seeking indemnification. In such event, the obligation of the Indemnifying Party to the party seeking indemnification shall be equal to the lesser of (i) the amount of the offer of settlement which the party seeking indemnification refused to accept plus the costs and expenses of such party prior to and including the date the Indemnifying Party notifies the party seeking indemnification of the offer of settlement and (ii) the actual out-of-pocket amount the party seeking indemnification is obligated to pay as a result of such party’s continuing to pursue such matter. An Indemnifying Party shall be entitled to recover from the party seeking indemnification any additional expenses incurred by such Indemnifying Party as a result of the decision of the party seeking indemnification to pursue such matter.

(5) In the event of a claim, action or proceeding against the Company which gives rise to any claim hereunder, if the Indemnifying Party has no right to defend the Company against such claim, action or proceeding, then the Indemnifying Party and Indemnified Party shall cooperate in good faith to mitigate any damages resulting from such claim, action or proceeding against the Company.

Section VII.4 Sole Remedy. The rights provided in this Agreement shall be the sole and exclusive remedy for any breach of or any inaccuracy in any of the representations and warranties of the Seller or the Purchaser contained in this Agreement, the Schedules or any other certificate or document delivered pursuant to this Agreement or otherwise relating hereto or in respect hereof, and the Purchaser shall not

-30-

assert any claim relating hereto or based hereon except by exercising its rights under this Agreement other than claims for fraud or willful misconduct and for the right to seek specific performance, injunctive relief or other equitable remedies.

Section VII.5 Indemnification as Adjustment to Interest Purchase Price. Any indemnification payment made pursuant to this Agreement shall be treated as an adjustment to the Interest Purchase Price.

Section VII.6 Limitation of Liability. Notwithstanding anything to the contrary or inconsistent in this Agreement or in any of the agreements, certificates or affidavits delivered by Seller pursuant to this Agreement, (i) Seller shall have no liability for any losses, claims, costs or expenses suffered or incurred by Purchaser as a result of the inaccuracy of any of the representations or warranties of Seller set forth in Article V hereof and/or under any of the schedules to this Agreement or any agreements, certificates or affidavits delivered by Seller pursuant to this Agreement (including the Manager’s Certificate) or for the breach of any covenant contained herein or in any such agreements, certificates or affidavits whether delivered on or prior to Closing, if (x) the same in the aggregate, shall have a monetary value (or be in a monetary amount claimed) of less than Twenty Five Thousand Dollars ($25,000) (the “Liability Floor”) or (y) Purchaser or any Affiliate shall have had actual knowledge (it being agreed that the actual knowledge of Purchaser for purposes of this clause (y) shall be limited to the actual knowledge of Marc Holliday and Andrew Levine (and not any implied, imputed or constructive knowledge of such individuals), without any independent investigation having been made or any implied duty to investigate) of the matter constituting or giving rise to such inaccuracy of any such representation or warranty by Seller, and (ii) the aggregate liability of Seller arising pursuant to or in connection with the inaccuracy of any of the representations or warranties of Seller set forth in Article V hereof and/or under any of the schedules to this Agreement or any agreements, certificates or affidavits delivered by Seller pursuant to this Agreement (including the Manager’s Certificate) or for the breach of any covenant contained herein or in any such agreements, certificates or affidavits whether delivered on or prior to Closing, shall not exceed Ten Million Dollars ($10,000,000) (the “Liability Cap”), in addition to any reasonable attorneys’ fees and expenses payable by Seller to Purchaser in connection with any legal action to recover on any such damage claim, provided that Purchaser is the prevailing party in any such action; provided, however, that if any claim for indemnification is based upon, attributable to or results from a breach of the representations and warranties set forth in Section 5.10(a), Section 5.10(c), Section 5.11 (with respect to the Shares only) or Section 5.13, or any covenant of Seller contained in Section 4.4, Section 14.17, Section 14.18, Section 14.19 or Article XI of this Agreement, neither the Liability Cap nor the

-31-

Liability Floor shall be applicable. It is expressly understood by the parties hereto that, except as otherwise set forth in this Agreement, Seller makes no representations, pursuant to this Agreement or otherwise, and the Seller shall not have any liability with respect to (i) the valuation of the Company Interests, or (ii) any and all projections or estimates in connection with the income or expenses of such Company Interests or Property.

If this Agreement is terminated as aforesaid, Escrow Agent shall promptly return the Deposit and the Interest to Purchaser and this Agreement shall terminate, and neither party shall have any further obligation under this Agreement except for those obligations which are expressly stated in this Agreement to survive. If Purchaser does not elect to terminate this Agreement as provided above, or if the portion of the Property so damaged or destroyed is not a Significant Portion of the Property, Purchaser shall accept the Property in its then “as is” condition with no abatement of the Purchase Price, and at the Closing Seller shall assign and turn over to Purchaser, and Purchaser shall be entitled

-44-

to receive and keep, all of Seller’s interest in and to all casualty insurance proceeds payable in connection with such casualty (except that the proceeds of any business interruption or rental value insurance payable to Seller shall be apportioned as of the Closing Date), and, to the extent the casualty was to a Significant Portion, Purchaser shall receive a credit against the Purchase Price at the Closing in the amount of Seller’s pro rata share of any loss deductible payable by Seller in connection with casualty coverage.

(25) Notwithstanding the foregoing, the parties (and each employee, representative, or other agent of either party) may disclose to any and all persons, without limitation of any kind, the tax treatment and any facts that may be relevant to the tax structure of the transaction; provided however, that neither party (nor any employee, representative or other agent thereof) may disclose any other information that is not relevant to understanding the tax treatment and tax structure of the transaction (including the identity of any party and any information that could lead another to determine the identity of any party) or any other information to the extent that such disclosure could result in a violation of any federal or state securities laws.

WITNESSETH:

WHEREAS, Landlord has requested that Tenant provide certain certifications with respect to the Lease (as such term is hereinafter defined) which may be relied upon by the Addressees;

NOW, THEREFORE, as of the date first set forth above, Tenant hereby certifies as follows:

2. The documents pursuant to which each portion of the Premises was demised to Tenant, and the term, Annual Basic Rent, deemed rentable square foot area, deemed building denominator, Tax Base Year, and the Operating Expense Base Year with respect each such portion of the Premises, are as set forth on the schedule annexed hereto and made a part hereof as Exhibit “B”.

5. Landlord is not in default of its obligations under the Lease and no event has occurred which, by the giving of notice or the passage of time, or both would constitute an event of default by Landlord under the Lease.
