If the Escrow Agent receives a notice of objection within said ten (10) calendar day period, or if for any other reason the Escrow Agent in good faith elects not to deliver the Deposit and the Interest, then the Escrow Agent shall have the right, at its option, to either continue to hold the Deposit and thereafter pay it to the party entitled thereto when the Escrow Agent receives (i) a notice from the objecting party withdrawing the objection, (ii) a notice signed by both parties directing disposition of the Deposit and Interest or (iii) a final judgment or order of a court of competent jurisdiction or deposit the same with a court of competent jurisdiction in the State of New York, and Escrow Agent shall rely upon the decision of such court or a written statement executed by both Seller and Purchaser setting forth how the Deposit and Interest should be released.

Escrow Agent shall accept the Deposit with the understanding of the parties that Escrow Agent is not a party to this Agreement except to the extent of its specific responsibilities hereunder, and does not assume or have any liability for the performance or non-performance of Purchaser or Seller hereunder to either of them.

3.3.2. The Escrow Agent shall be protected in relying upon the accuracy, acting in reliance upon the contents, and assuming the genuineness of any notice, demand, certificate, signature, instrument or other document which is given to the Escrow Agent without verifying the truth or accuracy of any such notice, demand, certificate, signature, instrument or other document;

3.3.3. The Escrow Agent shall not be bound in any way by any other agreement or understanding between the parties hereto, whether or not the Escrow Agent has knowledge thereof or consents thereto unless such consent is given in writing.

3.3.4. The Escrow Agent’s sole duties and responsibilities shall be to hold and disburse the Deposit and Interest accrued thereon in accordance with this Agreement.

3.3.5.

3.3.6. Upon the disbursement of the Deposit and Interest accrued thereon in accordance with this Agreement, the Escrow Agent shall be relieved and released from any liability under this Agreement.

3.3.7. The Escrow Agent may resign at any time upon at least ten (10) days prior written notice to the parties hereto. If, prior to the effective date of such resignation, the parties hereto shall all have approved, in writing, a successor escrow agent, then upon the resignation of the Escrow Agent, the Escrow Agent shall deliver the Deposit and Interest accrued thereon to such successor escrow agent. 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.

3.3.8. 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 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 as escrow agent or in carrying out the terms of this Agreement as escrow agent, except as a result of the Escrow Agent’s gross negligence, bad faith or willful misconduct.

3.3.9. Subject to the provisions of Section 3.2.5, in the event that a dispute shall arise in connection with this Agreement, or as to the rights of any of the parties in and to, or the disposition of, the Deposit and Interest, the Escrow Agent shall have the right to (w) hold and retain the Deposit and Interest until such dispute is settled or finally determined by litigation, arbitration or otherwise, or (x) deposit the Deposit and Interest in an appropriate court of law, following which the Escrow Agent shall thereby and thereafter be relieved and released from any

liability or obligation under this Agreement, or (y) institute an action in interpleader or other similar action permitted by stakeholders in the State of New York, or (z) interplead any of the parties in any action or proceeding which may be brought to determine the rights of the parties to all or any part of the Deposit.

3.3.10. The Escrow Agent shall not have any liability or obligation for loss of all or any portion of the Deposit by reason of the insolvency or failure of the institution of depository with whom the escrow account is maintained.

3.3.11. The parties hereto represent that prior to the negotiation and execution of this Agreement they were advised that the Escrow Agent was representing Seller as such party’s attorney in connection with this Agreement and the transaction referred to herein and the parties hereto covenant that they shall not object, on the grounds of conflict of interest or otherwise, to the Escrow Agent continuing to act as the attorney for Seller in connection with this Agreement and the transaction contemplated herein, or to act as Seller’s attorney in connection with any dispute in connection herewith or any other matter, as well as act as the Escrow Agent hereunder; provided, however, that the Escrow Agent deposits the Deposit and Interest with a court of competent jurisdiction or transfers the Deposit and all accrued Interest thereon to a mutually agreeable substitute escrow agent.

If Purchaser shall fail to adjourn the Scheduled Closing Date within the time periods set forth in this Section 4.1.3, then this Agreement shall automatically terminate and the Deposit and Interest shall be returned to the Purchaser and neither party shall have any obligations hereunder except those expressly stated to survive the termination of this Agreement.

4.1.4. If Seller elects to adjourn the Scheduled Closing Date as set forth in Section 4.1.2, but fails to obtain the Approvals and deliver same to Purchaser on or before the New Scheduled Closing Date, then Purchaser shall have the right either (I) to terminate this Agreement by giving notice thereof to Seller and Escrow Agent, in which event Purchaser shall be entitled to the return of the Deposit and Interest, and Seller shall pay all costs incurred by Purchaser in connection with this transaction, including, without limitation, due diligence costs, title costs and attorneys’ fees, in an aggregate amount not to exceed $500,000, and neither party shall have any obligations hereunder except those expressly stated to survive the termination of this Agreement or (II) to adjourn the New Scheduled Closing Date to a date no later than April 29, 2007, by written notice to Seller given on or before the New Scheduled Closing Date, during which period Seller shall use its commercially reasonable efforts to obtain the Approvals and deliver same to Purchaser on or before the date that is five (5) days prior to the Closing Date, as adjourned by Purchaser in accordance with this Section 4.1.4. If Seller has not obtained the Approvals and delivered same to Purchaser on or before the date that is five (5) days prior to the Closing Date as adjourned by Purchaser in accordance with this Section 4.1.4, then Purchaser shall have the right to either (I) waive the condition of the delivery of the Approvals and proceed to close or (II) terminate this Agreement by giving notice thereof to Seller and Escrow Agent, in which event, Purchaser shall be entitled to the return of the Deposit and Interest and Seller shall pay all costs incurred by Purchaser in connection with this transaction, including, without limitation, due diligence costs, title costs and attorneys’ fees, in an aggregate amount not to exceed $500,000 and neither party shall have any obligations hereunder except those expressly stated to survive the termination of this Agreement. If Purchaser shall fail to adjourn the Scheduled Closing Date within the time periods set forth in this Section 4.1.4, then this

Agreement shall automatically terminate and the Deposit and Interest shall be returned to the Purchaser and neither party shall have any obligations hereunder except those expressly stated to survive the termination of this Agreement.

4.1.5. Notwithstanding the foregoing, if Seller is unable to obtain the Approvals because (i) Purchaser is a Prohibited Person (as defined in the Ground Lease), (ii) Purchaser fails to satisfy any conditions to a transfer of the Ground Lease as set forth therein, or (iii) Purchaser fails to deliver the information and materials required under the terms of the Ground Lease, Seller shall have the right to terminate this Agreement by giving thirty (30) days written notice thereof to Purchaser and Escrow Agent, in which event, Purchaser shall be entitled to the return of the Deposit and Interest, provided that if Purchaser, with Seller’s cooperation, shall be able to provide such information or materials as shall meet the requirements for the Approvals and the Approvals are issued within such thirty (30) day period, then this Agreement shall remain in full force and effect.

4.1.6. As used herein “Closing Date” shall mean the date on which the Closing occurs. In order to facilitate the timely and expeditions closing of title and the payment of the Purchaser Price on the Closing Date, Seller and Purchaser shall conduct and complete a comprehensive pre-closing on the business day or business days (or may be necessary) prior to the Closing Date.

4.2. Prorations. All matters involving prorations, credits or adjustments to be made in connection with the Closing and not specifically provided for in another section of this Agreement shall be adjusted in accordance with this Section 4.2. Except as otherwise set forth herein, all items to be prorated pursuant to this Section 4.2 shall be prorated as of 11:59 P.M. on the day immediately preceding the Closing Date, with Purchaser to be treated as the owner of the Property, for purposes of prorations of income and expenses, on and after the Closing Date. Notwithstanding the foregoing, in the event that the Purchase Price is not disbursed to or as directed by Seller on or before 3:00 p.m. (eastern time) on the Closing Date, then, for purposes of this Section 4.2, the Closing shall be deemed to have occurred on the next business day and all adjustments shall be recomputed accordingly. Except as otherwise set forth herein, all prorations shall be done in accordance with the customs with respect to title closings recommended by The Real Estate Board of New York, Inc. All prorations and closing payments shall be made on the basis of a Proration Statement (as hereinafter defined) approved in writing by Purchaser and Seller as hereinafter set forth. If, subsequent to the Closing, Seller or Seller’s managing agent receives any rental checks from any Tenants made payable to Seller which relate to the period subsequent to the Closing, Seller shall endorse such checks to the payment of Purchaser and promptly deliver the same to Purchaser.

Not later than five (5) business days prior to the Closing Date, Seller will deliver to Purchaser a proposed “Proration Statement” which shall contain per diem amounts of all closing amounts to be prorated. Not later than three (3) business days prior to the Closing Date, Purchaser shall deliver to Seller a written statement of objection or agreement to such Proration Statement. Not later than two (2) business days prior to the Closing Date, Purchaser and Seller shall meet for the purpose of agreeing to and finalizing the Proration Statement, each of Purchaser and Seller hereby agree to act reasonably and in good faith in such discussions and determinations.

Any errors in apportionments pursuant to this Section 4.2 shall be corrected by appropriate re-adjustment between Seller and Purchaser subsequent to the Closing when the charge or error is determined.

The following items shall be prorated:

4.2.1. Property Taxes. Personal property taxes, business improvement district assessments and charges, vault charges and special assessments, if any, for the current fiscal year of the applicable taxing authority in which the Closing Date occurs. Seller shall pay all real estate and personal property taxes, business improvement district assessments and charges, vault charges and special assessments attributable to the Property through, but not including, the Closing Date. If the tax rate, assessment and/or assessed value for any of the foregoing items has not been set for the tax period in which the Closing occurs, then the proration of such items shall be based upon the rate, assessment and/or assessed value for the immediately preceding tax period and such proration shall be adjusted (within six (6) months after the Closing Date but subject to the rights of Seller and Purchaser under Section 8.6 hereof) in cash between Seller and Purchaser promptly upon presentation of written evidence that the actual amount paid for the tax period in which the Closing occurs differs from the amounts used in the calculation of the proration of such amounts in accordance with the provisions of Section 4.2.15 hereof. Any discount received for an early payment shall be for the benefit of Seller.

4.2.2. Ground Rent. All rents and other amounts due to Ground Lessor under the Ground Lease such that Seller shall pay and be responsible for all of the same attributable to the Land and Improvements to but not including the Closing Date and Purchaser shall pay and be responsible for all of the same attributable to the Land and Improvements on and after the Closing Date; provided, however, that only the portion of rents payable under the Ground Lease as cash (as opposed to credits available to Seller for application towards rental payments under the Ground Lease) shall be adjusted. Credits available to Seller pursuant to the LADA and applied in partial satisfaction of rental payments under the Ground Lease shall not be included in such adjustments.

4.2.3. Insurance Premiums. There shall be no proration of Seller’s insurance premiums, or assignment of Seller’s insurance policies with respect to the Property, and Seller shall cancel all of its existing policies with respect to the Property as of the Closing Date.

4.2.4. Utilities and Services. Purchaser and Seller hereby acknowledge and agree that the amounts of all telephone, electric, sewer, water, gas, steam and other utility bills, trash removal bills, janitorial and maintenance service bills and all other operating and administrative expenses relating to the Property and allocable to the period prior to the Closing Date (other than such items which are the obligation of and directly paid by a Tenant under its Lease) shall be determined and paid by Seller before Closing, if possible, or shall be paid thereafter by Seller or adjusted between Purchaser and Seller immediately after the same have been determined. Seller shall have all base building meters read as of the Closing Date or within

five (5) business days thereafter. Purchaser shall cause all utility services to be placed in Purchaser’s name as of the Closing Date. All deposits, if any, furnished by Seller to any utility company or other service provider shall be retained by or refunded to Seller by the utility company or other service provider.

4.2.5. Base Rents. Base or fixed rents due under Leases (“Fixed Rent”) shall be adjusted on an if, as and when collected basis. If, on the Closing Date, any tenant under a Lease (a “Tenant”) is in arrears in the payment of such rent, then any amounts received by Seller or Purchaser from any such Tenant after the Closing on account of such rent (net of reasonable costs of collection, including reasonable attorneys fees and disbursements) shall be applied in the following order of priority: (i) first to the payment of monies owed to Seller and Purchaser for the billing period in progress on the Closing Date, (ii) second to any current sums and arrearages owed to Purchaser (relating to billing periods after the billing period in progress as of the Closing Date), and (iii) last to Seller for the period prior to the month in which the Closing occurred. If rents or any portion thereof received by Seller or Purchaser after the Closing are payable to the other party by reason of this allocation, the appropriate sum shall be promptly paid to the other party. At Closing, Seller shall deliver to Purchaser a schedule of any rent which is delinquent as of the Closing Date. Notwithstanding anything contained herein to the contrary, (A) Seller shall have the right, at its sole cost and expense, to pursue in its own name after the Closing any tenants to collect delinquencies for periods prior to the Closing (including, without limitation, by the prosecution of an action or proceeding, provided that with respect to tenants who are, at the time in question, in occupancy of any portion of the Property, no such action or proceeding shall require the eviction of any such tenant without the Purchaser’s consent, which consent shall be granted in Purchaser’s sole and absolute discretion, and in which event all sums collected by Seller as a result of such litigation (after payment of all costs and expenses) shall be applied in full satisfaction of the subject delinquencies), and (B) with respect to Tenants who are, at the time in question, in occupancy of a portion of the Property, Purchaser agrees that it shall use commercially reasonable efforts to collect any such delinquent rents allocable to the period of Seller’s ownership of the Property provided that in no event shall such efforts require the eviction of any such tenant unless Purchaser shall agree thereto in writing, and in which event all sums collected by Purchaser as a result of such litigation (after payment of all costs and expenses, including reasonable attorneys’ fees) shall be applied in full satisfaction of the subject delinquencies. Seller shall furnish to Purchaser such accurate information (based on Seller’s records) relating to the period prior to the Closing that is reasonably necessary for the billing of such Fixed Rent. Purchaser shall bill Tenants for Fixed Rent for accounting periods prior to the Closing in accordance with and on the basis of such information furnished by Seller. Subsequent to the Closing, Seller shall have the right, from time to time for a period of ninety (90) days following the Closing, to review Purchaser’s rental records with respect to the Property during Purchaser’s ordinary business hours, at Purchaser’s offices, to ascertain the status of Purchaser’s billing and collection of Fixed Rent. No action which results in the compromising of any claim against any Tenant with respect to base or fixed rents due under such Tenant’s Lease for the period prior to the Closing shall be made without Seller’s prior written approval, which approval shall not be unreasonably withheld, delayed or conditioned. No legal action or proceeding to collect Fixed Rent shall be first commenced by Seller against a Tenant after the date which is six (6) months after the Closing Date.

4.2.6. Additional Rents. (a) If any Tenants are required to pay percentage rents, charges for operating expenses, escalation charges for increases in operating expenses, if any, business improvement district assessments, theater surcharges pursuant to any of the Project Documents, porter’s wage increases, labor cost increases, cost-of-living increases, charges for electricity, water, cleaning or overtime services, work order charges, “sundry charges” or other charges of a similar nature (collectively, “Additional Rents”), the same shall be adjusted on an if, as and when collected basis. With respect to any estimated Additional Rents paid or payable by Tenants for any period prior to the Closing which, pursuant to the applicable Lease, are to be recalculated after the Closing based upon actual expenses and other relevant factors, (i) Seller agrees, with respect to such adjustments which are in favor of any such Tenant, to pay to Purchaser the amount of such adjustment (after which Purchaser shall pay directly to the Tenant in question), within fifteen (15) days after written demand and presentation to Seller of documentation in support of such adjustments, and (ii) Purchaser agrees, with respect to such adjustments which are in favor of landlord, to pay to Seller the amount of such adjustments which the Tenant pays to Purchaser, within fifteen (15) days after receipt thereof by Purchaser. Purchaser agrees that it shall, in accordance with Purchaser’s standard practice in the management and operation of the Real Property, bill Tenants such Additional Rents attributable to an accounting period that shall have expired prior to the Closing in the same manner that Purchaser bills tenants for Additional Rents in respect of an accounting period that shall expire after the Closing (including without limitation, the annual “true up” at the end of each calendar year). Notwithstanding anything contained herein to the contrary, (A) Seller shall have the right, at its sole cost and expense, to pursue in its own name after the Closing any tenants to collect delinquencies for periods prior to the Closing (including, without limitation, by the prosecution of an action or proceeding, provided that with respect to tenants who are, at the time in question, in occupancy of any portion of the Property, no such action or proceeding shall require the eviction of any such tenant without the Purchaser’s consent, and in which event all sums collected by Seller as a result of such litigation (after payment of all costs and expenses) shall be applied in full satisfaction of the subject delinquencies), and (B) with respect to Tenants who are, at the time in question, in occupancy of a portion of the Property, Purchaser agrees that it shall use commercially reasonable efforts to collect any such delinquent Additional Rent allocable to the period of Seller’s ownership of the Property provided that in no event shall such efforts require the eviction of any such tenant unless Purchaser shall agree thereto in writing, and in which event all sums collected by Purchaser as a result of such litigation (after payment of all costs and expenses) shall be applied in full satisfaction of the subject delinquencies). Seller shall furnish to Purchaser such accurate information (based on Seller’s records) relating to the period prior to the Closing that is reasonably necessary for the billing of such Additional Rents. Purchaser shall bill Tenants for Additional Rents for accounting periods prior to the Closing in accordance with and on the basis of such information furnished by Seller. Subsequent to the Closing, Seller shall have the right, from time to time for a period of ninety (90) days following the Closing, to review Purchaser’s rental records with respect to the Property during Purchaser’s ordinary business hours, at Purchaser’s offices, to ascertain the status of Purchaser’s billing and collection of Additional Rent. No action which results in the compromising of any claim against any Tenant with respect to base or fixed rents due under such Tenant’s Lease for the period prior to the Closing shall be made without Seller’s prior written approval, which approval shall not be unreasonably withheld, delayed or conditioned. No legal action or proceeding to collect Additional Rent shall be first commenced by Seller against a Tenant after the date which is six (6) months after the Closing Date.

With respect to any Tenant which has paid all Additional Rents due and payable to the Closing Date, if, prior to the Closing, Seller or Seller’s managing agent shall have actually received and collected any installments or other amounts of Additional Rents from such Tenant attributable to Additional Rents for periods from and after the Closing Date, then, Purchaser shall receive a credit against the Balance of the Purchase Price in the amount of such installments or other amounts of Additional Rents at the Closing.

(b) Any Additional Rents collected by Purchaser or Seller after the Closing from Tenants who owe Additional Rents for periods prior to the Closing (to the extent not applied against Fixed Rents due and payable by such Tenant in accordance with Section 4.2.5 above) shall be applied to Additional Rents then due and payable in the following order of priority (i) first, in payment of Additional Rents for the accounting period in which the Closing Date occurs, with such amounts being prorated between Purchaser and Seller based upon the number of days each owned the Property during the accounting period in which the Closing occurs; (ii) second, in payment of Additional Rents for any accounting periods which commenced after the Closing occurs, but only to the extent payments of Additional Rents for such accounting period are then currently due; and (iii) third, in payment of Additional Rents for accounting periods preceding the accounting period prior to the accounting period in which the Closing occurs. Notwithstanding the foregoing, (I) if any Additional Rents are collected by Purchaser after the Closing Date which are expressly attributable in whole or in part to any period prior to the Closing, then Purchaser shall promptly pay to Seller its proportionate share thereof, (II) if any Additional Rents are collected by Seller after the Closing Date which are expressly attributable in whole or in part to any period prior to the Closing, then Seller may retain its proportionate share thereof, and (III) any funds collected by Purchaser for Additional Rents as the result of an end of billing period “true up” that are in favor of landlord, shall be divided between Seller and Purchaser based upon the number of months each held the landlord’s interest in the Property for such billing period. At the Closing, Purchaser shall receive a credit against the Balance of the Purchase Price for any rents or other amounts paid by Tenants pursuant to the Leases actually received and collected by Seller prior to Closing, but that correspond to real estate taxes, operating expenses or other charges which are not due and payable until after the Closing.

4.2.7. Reserved.

4.2.8. Brokerage Commissions and Tenant Improvements.

(i) Seller and Purchaser shall each be responsible for the payment of those leasing commissions and referral fees (collectively, “Leasing Commissions”) relating to Existing Leases executed prior to the date hereof (the “Leasing Cut-off Date”) as set forth on Schedule 4.2.8(i) attached to this Agreement, as the same become due and payable, it being the intention that (except as otherwise provided in Schedule 4.2.8(i)), (A) Seller shall be responsible for the payment of all Leasing Commissions relating to Existing Leases other than Leasing

Purchaser shall reimburse Seller as an adjustment item to the extent Seller has paid any Leasing Commissions which are the responsibility of Purchaser under the preceding sentence. Seller represents and warrants, except as set forth on Schedule 4.2.8(i), there are no other Leasing Commissions as of the date hereof payable in connection with the Existing Leases.

(ii) Seller and Purchaser shall each be responsible for the payment of all tenant improvement expenses (including all hard and soft construction costs, whether payable to the contractor or to the tenant), tenant allowances, tenant “buy-out” or lease surrender costs, work allowances and work letters, free rent, rent allowances or rent credit (and, in the case of any such inducement not paid in cash, the dollar value thereof), legal fees and expenses, moving allowances and other out-of-pocket costs (collectively, the “Tenant Allowances”) as set forth on Schedule 4.2.8(ii) attached to this Agreement, as the same become due and payable, it being the intention that (except as otherwise provided in Schedule 4.2.8(ii)), (A) Seller shall be responsible for the payment of all Tenant Allowances which are the obligation of the landlord under the Existing Leases and (B) Purchaser shall be responsible for the payment of all Tenant Allowances to the extent they become due and payable during the term of Existing Leases and (i) do not relate to the initial occupancy by the tenants thereunder, or (ii) relate to renewal periods or additional space under renewal options, expansion options or first offer rights, under the Existing Leases exercised on or after the Leasing Cut-off Date or otherwise agreed to by Purchaser after the Leasing Cut-off Date. Seller shall reimburse Purchaser as an adjustment item to the extent Seller has not paid any Tenant Allowance prior to the Closing which are the responsibility of the Seller under the preceding sentence. Purchaser shall reimburse Seller as an adjustment item to the extent Seller has paid any Tenant Allowances prior to Closing which are the responsibility of Purchaser under the preceding sentence. Seller shall in no event be obligated to pay for any increased costs relating to change orders or additions to the tenant improvements or changes in the scope of the work or the specifications agreed to by Purchaser and issued on or after the Leasing Cut-off Date with respect to Existing Leases. Seller represents and warrants, except as set forth on Schedule 4.2.8(ii) there are no other Tenant Allowances payable in connection with the Existing Leases.

4.2.9. Employees. Salaries, wages, vacation pay, bonuses and any other fringe benefits (including, without limitation, social security, unemployment compensation, employee disability insurance, sick pay, welfare and pension fund contributions, payments and deposits, if any) of all Employees (as hereinafter defined).

Each Revenue Support Payment shall be paid on the first day of each calendar month after the Closing; provided, however, that with respect to the month in which the Closing occurs, Seller shall pay to Purchaser at Closing an amount equal to the product of (i) a fraction, the numerator of which is the number of days remaining in such month (inclusive of the Closing Date) and the denominator of which shall be the total number of days in such month and (ii) the Revenue Support Payment applicable for the period in which the Closing occurs. Each Revenue Support Payment shall be deemed to constitute an adjustment to the Purchase Price paid by the Purchaser hereunder.

(iii) The provisions of this Section 4.2.14 shall survive the Closing.

4.2.15. Method of Calculation. For purposes of calculating prorations, Purchaser shall be deemed to be the owner of the Property, and therefore entitled to the income therefrom and responsible for the expenses thereof for the entire day upon which the Closing occurs, and thereafter all such prorations shall be made on the basis of the actual number of days of the month which shall have elapsed as of the day of the Closing and based upon the actual number of days in the month and a three hundred sixty five (365) day year. Seller and Purchaser agree to use reasonable efforts to calculate all adjustments required under this Article IV (and to make the adjustment payments resulting from such calculations) with respect to those items of income and expense which are ascertainable on the Closing Date by no later than twenty (20)

days after the Closing Date. Each other item of income and expense which is subject to adjustment under this Article IV, but which is not ascertainable on the Closing Date will be adjusted retroactive to the Closing Date, and the payment made on such adjustment within sixty (60) days after the date that such adjustment becomes ascertainable, i.e., the date by which each party, in its good faith business judgment, has sufficient information to make such adjustment. The parties agree that each party shall have the right following Closing, on reasonable written notice to the other, from time to time to review the books and records of such other party pertaining solely to the operations of the Property to the extent reasonably necessary to confirm the amounts of adjustments payable to Seller and/or Purchaser following the Closing, and Seller and Purchaser shall instruct any property manager to make its books and records available for this purpose. Purchaser and Seller shall cooperate as necessary following the Closing in order to promptly and in good faith discharge their respective obligations under this Article IV. Notwithstanding the foregoing and subject to Section 8.6 hereof, any claim for an adjustment under Section 4.2 will be valid if made in writing with reasonable specificity within one (1) year after the Closing Date, except in the case of items of adjustment which at the expiration of such period are subject to pending litigation or administrative proceedings. Claims with respect to items of adjustment which are subject to litigation or administrative proceedings will be valid if made on or before the later to occur of (i) the date that is one (1) year after the Closing Date and (ii) the date that is one hundred eighty (180) days after a final order shall have issued in such litigation or administrative hearing. Both parties shall use good faith efforts to resolve any disputed claims promptly.

4.2.16. Survival. The provisions of this Section 4.2 shall survive the Closing.

4.3. Transfer Taxes. Seller shall pay at Closing all transfer taxes imposed upon the conveyance of the Property hereunder pursuant to Section 1402 of the New York State Tax Law and Title 11 of Chapter 21 of the Administrative Code of the City of New York (the “Transfer Taxes”) and agrees to indemnify and hold Purchaser harmless with respect thereto. Seller shall file or cause to be filed all necessary tax returns with respect to all such Transfer Taxes and, to the extent required by applicable law, Purchaser will join in the execution of any such tax returns. The provisions of this Section 4.3 shall survive the Closing.

4.4. Sales Taxes. Although it is not anticipated that any sales tax shall be due and payable, Purchaser agrees that Purchaser shall pay any and all New York State and New York City sales and/or compensating use taxes imposed upon or due in connection with the transactions contemplated hereunder under Sections 1105, 1107, 1109 and 1110 of the New York State Tax Law and any successor provisions thereto or replacement provisions thereof. Purchaser shall file all necessary tax returns with respect to all such taxes and, to the extent required by applicable law, Seller will join in the execution of any such tax returns.

Purchaser shall pay all title insurance premiums, title examination fees and survey costs incurred by Purchaser.

Seller shall pay for all costs and charges in connection with the preparation and delivery of Seller’s Title Report (as hereinafter defined). All other costs, fees, expenses and charges of any kind incident to the sale and conveyance of the Property from Seller to Purchaser, including attorneys’ fees and consultants’ fees, shall be borne by the party incurring the same.

4.5.2. Seller shall (i) take any action as may be required by the Ground Lease to notify Ground Lessor of the transactions contemplated hereby and (ii) pay at Closing any Transaction Payment (as defined in the Ground Lease) required to be paid in connection with the Assignment of Ground Lease in accordance therewith. Seller shall indemnify and hold Purchaser harmless from any and all claims, losses, liabilities and lawsuits arising from or as a result of Seller’s failure to pay all or any portion of the Transaction Payment.

Title and Survey Matters

5.1. Title.

5.1.1. Updated Commitment and Survey. Purchaser shall, at its sole cost and expense, within five (5) business days from the date hereof, order a title insurance commitment for an owner’s policy of title insurance for the Real Property (the “Purchaser’s Title Commitment”) from any nationally recognized title insurance company (the “Title Company”), setting forth the status of title to the Real Property and any defects in or objections or exceptions to title to the Real Property, together with true and correct copies of all instruments giving rise to such defects, objections or exceptions. Purchaser shall instruct the Title Company to forward a copy of the Purchaser’s Title Commitment and any updates thereof to Seller’s attorney simultaneously with the issuance thereof to Purchaser. Seller has delivered to Purchaser a copy of a survey of the Real Property, dated December 9, 2002 and most recently visually certified as of October 13, 2005, as prepared by Earl B. Lovell – S.P. Belcher, Inc. (the “Survey”). Purchaser shall instruct the surveyor to forward a copy of any updated Survey and any further updates thereof to Seller’s attorney and the Title Company simultaneously with the issuance thereof to Purchaser.

5.1.2. Title Objections. If the Purchaser’s Title Commitment or any update of either the Survey or the Purchaser’s Title Commitment shall reveal or disclose any defects, objections or exceptions in the title to the Real Property which are not Permitted Exceptions (as hereinafter defined) and to which Purchaser objects (“Title Objections”), then Purchaser (or Purchaser’s counsel) shall notify Seller (or Seller’s counsel) of such Title Objections in writing within ten (10) days of Purchaser’s receipt thereof.

If Purchaser does not notify Seller in writing of any such Title Objections within the time period set forth in this Section 5.1.2, then Purchaser shall be deemed to have accepted the state of title to the Real Property reflected in the Purchaser’s Title Commitment, the Survey or any updates of either received by Purchaser and to have waived any claims or defects which it might otherwise have raised with respect to the matters reflected therein and the same shall be deemed to be Permitted Exceptions for all purposes of this Agreement.

5.1.3. Permitted Exceptions.

(a) Seller’s Title Report. Purchaser acknowledges receipt of a copy of (a) a commitment for an owner’s title insurance policy for the Real Property prepared by Fidelity Title Insurance Company under its Title No. 06-7406-14812-NYM (the “Seller’s Title Report”), together with copies of all instruments giving rise to any defects, objections or exceptions noted in such commitment and (b) the Survey. At the Closing, Seller shall convey and Purchaser shall accept leasehold title to the Real Property subject only to the Permitted Exceptions.

(b) Permitted Exceptions to Title. The Property shall be sold and conveyed subject to the following exceptions to title (the “Permitted Exceptions”):

(1) any state of facts shown on the Survey and any state of facts an accurate survey would show provided such additional state of facts do not render title to the Property unmarketable;

If, as of the Closing Date, there are any Title Objections (which are not Permitted Exceptions or are not otherwise omitted from Purchaser’s title insurance policy without the payment of additional premiums), then, subject to Seller’s right to adjourn the Closing Date for up to sixty (60) days, but in no event shall the Closing Date be adjourned beyond April 29, 2007, in the aggregate in order to eliminate any Title Objections or Voluntary Encumbrances, Purchaser shall have the right (as its sole and exclusive remedy with respect to such matters) either (I) to terminate this Agreement by delivering notice thereof to Seller, in which event Purchaser shall be entitled to the return of the Deposit and Interest and Seller shall pay all costs incurred by Purchaser in connection with this transaction, including, without limitation, due diligence costs, title costs and attorneys’ fees, in an aggregate amount not to exceed $500,000, and neither party shall have any obligations hereunder except those expressly stated to survive the termination of this Agreement, or (II) to waive, in writing, its objection thereto and consummate the Closing, in which event (i) such Title Objections shall thereupon constitute Permitted Exceptions for all purposes of this Agreement and (ii) Seller shall be obligated, at Closing, to remove any Voluntary Encumbrances which are not Permitted Exceptions and Purchaser shall be entitled to a credit against the Balance of the Purchase Price in an amount equal to the sum of (x) the amount necessary to discharge of record all of the unsatisfied Monetary Encumbrances and (y) the lesser of (Y) the amount necessary to discharge of record all of the unsatisfied Other Liens or (Z) $25,000,000. Seller agrees that Seller shall not voluntarily enter into any agreement to create a lien or encumbrance on the Property after the date hereof without Purchaser’s prior written consent, which consent may be granted in Purchaser’s sole and absolute discretion.

5.1.5. Payment from Balance of the Purchase Price. Any unpaid water charges, sewer rents and assessments, together with the interest and penalties thereon to a date not more than five (5) business days following the Closing Date (in each case subject to any applicable apportionment), and any Monetary Encumbrances or Other Liens, together with the cost of recording or filing any instruments necessary to discharge such Monetary Encumbrances or Other Liens, may be paid out of the proceeds of the Balance of the Purchase Price payable at the Closing. Seller hereby agrees to deliver to Purchaser’s Title Company, on the Closing Date, instruments in recordable form sufficient to discharge any such Monetary Encumbrances or Other Liens and to cause the Title Company to omit same from the Title Commitment. Upon request of Seller, delivered to Purchaser no later than two (2) business days prior to the Closing, Purchaser shall provide at the Closing a wire transfer of federal funds as Seller shall direct, in an aggregate amount not to exceed the Balance of the Purchase Price, as adjusted for apportionments required under this Agreement, payable at the Closing.

5.1.6. Affidavits. If the Purchaser’s Title Commitment discloses judgments, bankruptcies or other returns against other persons having names the same as or similar to that of Seller, Seller, on request, shall deliver to the Title Company affidavits showing that such judgments, bankruptcies or other returns are not against Seller, in form reasonably acceptable to the Title Company and to Seller.

5.2. Violations. Purchaser agrees to purchase the Property subject to any and all notes or notices of violations of law, or municipal ordinances, orders, designations or requirements whatsoever noted in or issued by any federal, state, municipal or other governmental department, agency or bureau or any other governmental authority having jurisdiction over the Property

(collectively, “Violations”), or any condition or state of repair or disrepair or other matter or thing, whether or not noted, which, if noted, would result in a violation being placed on the Property. Seller shall have no duty to remove or comply with or repair any condition, matter or thing, whether or not noted, which, if noted, would result in a violation being placed on the Property, Seller shall have no duty to remove or comply with or repair any of the aforementioned Violations, or other conditions, and Purchaser shall accept the Property subject to all such Violations, the existence of any conditions at the Property which would give rise to such Violations, if any, and any governmental claims arising from the existence of such Violations, in each case without any abatement of or credit against the Purchase Price. Notwithstanding the foregoing to the contrary, Seller agrees to use its commercially reasonable efforts to remedy and/or discharge Environmental Control Board violation number 344585468 prior to the Closing (but such remedy or discharge shall not be a condition to Closing hereunder) and if such violation is not discharged prior to Closing, Seller shall indemnify and hold Purchaser harmless from any and all claims, losses and liabilities arising from or as a result of such violation. BPLP shall guaranty the obligations of Seller under the foregoing indemnity as and to the extent provided in the Guaranty Agreement.

Risk of Loss

11.1. Casualty.

11.1.1. If all or any part of the Property is damaged by fire or other casualty occurring following the date hereof and prior to the Closing, whether or not such damage affects a material part of the Real Property, then:

(a) if the estimated cost of repair or restoration is less than or equal to $25,000,000 and if the estimated time to complete such repair or restoration is twelve (12) months or less as determined in accordance with Section 11.1.2, neither party shall have the right to terminate this Agreement and the parties shall nonetheless consummate this transaction in accordance with this Agreement, without any abatement of the Purchase Price or any liability or obligation on the part of Seller by reason of said destruction or damage. In such event, Seller shall assign by written instrument in form reasonably satisfactory to Purchaser and Purchaser shall have the right to make a claim for and to retain any casualty insurance proceeds received under the casualty insurance policies and any rental interruption insurance (but not business interruption insurance) in effect with respect to the Property on account of said physical damage or destruction as shall be necessary to perform repairs to the Improvements and/or to rebuild the Improvements to substantially the same condition as it existed prior to the occurrence of such fire or other casualty and Purchaser shall receive a credit against the cash due at Closing for the amount of the deductible on such casualty insurance policy.

(b)(i) if the estimated cost of repair or restoration exceeds $25,000,000 or (ii) if the estimated time to complete such repair or restoration exceeds twelve (12) months Purchaser shall have the option, exercisable within thirty (30) days after receipt of (i) notice of the occurrence of such fire or other casualty and (ii) such factual information regarding the casualty and availability of insurance proceeds as is reasonably sufficient to enable Purchaser to make an informed decision about whether or not to proceed to Closing, time being of the essence, to terminate this Agreement by delivering notice thereof to Seller and Escrow Agent, whereupon the Deposit and Interest shall be returned to Purchaser and this Agreement shall be deemed canceled and of no further force or effect, and neither party shall have any further rights

or liabilities against or to the other except for such provisions which are expressly provided in this Agreement to survive the termination hereof. If a fire or other casualty described in this clause (b) shall occur and Purchaser shall not have timely elected to terminate this Agreement, then Purchaser and Seller shall consummate this transaction in accordance with this Agreement, without any abatement of the Purchase Price or any liability or obligation on the part of Seller by reason of said destruction or damage, Seller shall assign to Purchaser by written instrument in form reasonably satisfactory to Purchaser and Purchaser shall have the right to make a claim for and to retain any casualty insurance proceeds received under the casualty insurance policies in effect with respect to the Property on account of said physical damage or destruction as shall be necessary to perform repairs to the Improvements and/or to rebuild the Improvements to substantially the same condition as it existed prior to the occurrence of such fire or other casualty and Purchaser shall receive a credit from the cash due at Closing for the amount of the deductible on such casualty insurance policy.

(c) Notwithstanding the provisions of subsections (a) or (b) above, if all or any part of the Property is damaged by fire or other casualty and as a result thereof, E&Y has the right to terminate its lease, then Purchaser shall have the right to terminate this Agreement by delivering notice thereof to Seller and Escrow Agent, whereupon the Deposit and Interest shall be returned to Purchaser and this Agreement shall be deemed canceled and of no further force or effect, and neither party shall have any further rights or liabilities against or to the other except for such provisions which are expressly provided in this Agreement to survive the termination hereof; provided, however, that if E&Y shall waive in writing its right to terminate its lease, then Purchaser shall not have the right under this subsection (c) to terminate this Agreement.

(d) If all or any part of the Property is damaged by fire or other casualty and, pursuant to subsections (a) or (b) above, neither Seller nor Purchaser elects to terminate this Agreement, Seller shall assign by written instrument in form reasonably satisfactory to Purchaser and Purchaser shall have the right to make a claim for and to retain any rental interruption insurance proceeds received under the casualty insurance policies in effect with respect to the Property on account of said physical damage or destruction; provided, however, that if Seller is unable to assign to Purchaser such rental interruption insurance proceeds, then (i) if the estimated rental insurance proceeds applicable to such fire or other casualty are less than $5,000,000 as determined in accordance with Section 11.1.2, Seller shall pay to Purchaser directly funds in equivalent amounts and otherwise on the same basis, as such proceeds would have been payable by Seller’s insurance carrier (and Purchaser shall diligently proceed to repair and restore the Property as a result of such casualty), and (ii) if the estimated rental insurance proceeds applicable to such fire or other casualty are greater than $5,000,000 as determined in accordance with Section 11.1.2, Seller may, in its sole and absolute discretion, elect to pay to Purchaser directly funds in equivalent amounts and otherwise on the same basis, as such proceeds would have been payable by Seller’s insurance carrier (and Purchaser shall diligently proceed to repair and restore the Property as a result of such casualty) and if Seller does not elect to make the payments to Purchaser as contemplated under this clause (ii), then Purchaser shall have the right to terminate this Agreement by delivering notice thereof to Seller and Escrow Agent, whereupon the Deposit and Interest shall be returned to Purchaser and this

Agreement shall be deemed canceled and of no further force or effect, and neither party shall have any further rights or liabilities against or to the other except for such provisions which are expressly provided in this Agreement to survive the termination hereof.

11.1.2. The estimated cost to repair and/or restore and the estimated time to complete contemplated in Section 11.1.1 above shall be established by estimates obtained by Seller from independent contractors, subject to Purchaser’s review and reasonable approval of the same and the provisions of Section 11.1.3 below.

11.1.3. Any disputes under this Article XI as to the cost of repair or restoration or the time for completion of such repair or restoration shall be resolved by expedited arbitration before a single arbitrator acceptable to both Seller and Purchaser in their reasonable judgment in accordance with the rules of the American Arbitration Association; provided that if Seller and Purchaser fail to agree on an arbitrator within five days after a dispute arises, then either party may request The Real Estate Board of New York, Inc., to designate an arbitrator. Such arbitrator shall be an independent architect or engineer having at least ten (10) years of experience in the construction of office buildings in Manhattan. The determination of the arbitrator shall be conclusive and binding upon the parties. The costs and expenses of such arbitrator shall be borne equally by Seller and Purchaser.

11.2. Condemnation. If, prior to the Closing Date, any part of the Property is taken (other than a temporary taking), or if Seller shall receive an official notice from any governmental authority having eminent domain power over the Property of its intention to take, by eminent domain proceeding, any part of the Property (a “Taking”), then:

(a) if such Taking involves (i) one percent (1%) or less of the rentable area of the Improvements as determined by an independent architect chosen by Seller (subject to Purchaser’s review and reasonable approval of such determination and the provisions of Section 11.2.2 below), or (ii) restoration work costing $10,000,000 or less, then neither party shall have any right to terminate this Agreement, and the parties shall nonetheless consummate this transaction in accordance with this Agreement, without any abatement of the Purchase Price or any liability or obligation on the part of Seller by reason of such Taking; provided, however, that Seller shall, on the Closing Date, (i) assign and remit to Purchaser, and Purchaser shall be entitled to receive and keep, the net proceeds of any award or other proceeds of such Taking which may have been collected by Seller as a result of such Taking less the reasonable expenses incurred by Seller in connection with such Taking, or (ii) if no award or other proceeds shall have been collected, deliver to Purchaser, an assignment of Seller’s right to any such award or other proceeds which may be payable to Seller as a result of such Taking and Purchaser shall reimburse Seller for the reasonable expenses incurred by Seller in connection with such Taking.

(b) if such Taking involves (i) more than one percent (1%) of the rentable area of the Property as determined by an independent architect chosen by Seller (subject to Purchaser’s review and reasonable approval of such determination and the provisions of Section 11.2.2 below), or (ii) restoration work exceeding $10,000,000, then Purchaser shall have the option, exercisable within thirty (30) days after receipt of notice of such Taking and such

factual information regarding the Taking and the availability of awards or other proceeds of such Taking as is reasonably sufficient to enable Purchaser to make an informed decision about whether or not to proceed to Closing, time being of the essence, to terminate this Agreement by delivering notice thereof to the other party, whereupon the Deposit (together with any interest earned thereon) shall be returned to Purchaser and this Agreement shall be deemed canceled and of no further force or effect, and neither party shall have any further rights or liabilities against or to the other except pursuant to the provisions of this Agreement which are expressly provided to survive the termination hereof. If a Taking described in this clause (b) shall occur and Purchaser shall not have timely elected to terminate this Agreement, then Purchaser and Seller shall consummate this transaction in accordance with this Agreement, without any abatement of the Purchase Price or any liability or obligation on the part of Seller by reason of such Taking; provided, however, that Seller shall, on the Closing Date, (i) assign and remit to Purchaser, and Purchaser shall be entitled to receive and keep, the net proceeds of any award or other proceeds of such Taking which may have been collected by Seller as a result of such Taking less the reasonable expenses incurred by Seller in connection with such Taking, or (ii) if no award or other proceeds shall have been collected, deliver to Purchaser, an assignment of Seller’s right to any such award or other proceeds which may be payable to Seller as a result of such Taking and Purchaser shall reimburse Seller for the reasonable expenses incurred by Seller in connection with such Taking.

11.2.2. Any disputes under this Article XI as to whether the Taking involves more than one percent (1%) of the rentable area of the Property shall be resolved by expedited arbitration before a single arbitrator acceptable to both Seller and Purchaser in their reasonable judgment in accordance with the rules of the American Arbitration Association; provided that if Seller and Purchaser fall to agree on an arbitrator within five days after a dispute arises, then either party may request The Real Estate Board of New York, Inc. to designate an arbitrator. Such arbitrator shall be an independent architect having at least ten (10) years of experience in the construction of office buildings in Manhattan. The costs and expenses of such arbitrator shall be borne equally by Seller and Purchaser.

11.3. General Obligations Law. The provisions of this Article XI are intended to supersede those of Section 5-1311 of the General Obligations Law of New York.

ARTICLE XII.

Default

12.1. Default by Seller. (a) Except as set forth below, in the event the Closing and the transactions contemplated hereby do not occur as provided herein by reason of a default of Seller, Purchaser may elect, as the sole and exclusive remedy of Purchaser, to (i) terminate this Agreement and receive the Deposit and Interest from the Escrow Agent in accordance with the terms and provisions of Section 3.2 hereof, and in such event Seller shall not have any liability whatsoever to Purchaser hereunder other than with respect to the Surviving Termination Obligations, or (ii) enforce specific performance of this Agreement.

(b) Notwithstanding the foregoing, from and after the Closing, nothing contained in this Section 12.1 shall limit Purchaser’s remedies at law or in equity as to the Surviving Termination Obligations.

12.2. Default by Purchaser. In the event the Closing and the transactions contemplated hereby do not occur as provided herein by reason of the default of Purchaser, and provided that such default is not cured by Purchaser within ten (10) days of receipt of notice of such default from Seller, (including without limitation, Purchaser’s failure to comply with the requirements of Section 9.1 hereof), Purchaser and Seller agree it would be impractical and extremely difficult to fix the damages which Seller may suffer. Therefore, Purchaser and Seller hereby agree a reasonable estimate of the total net detriment Seller would suffer in the event Purchaser defaults and fails to complete the purchase of the Property is and shall be, as Seller’s sole and exclusive remedy (whether at law or in equity), a sum equal to the Deposit and Interest accrued thereon. Upon such default by Purchaser and failure to close as required hereunder, Seller shall have the right to receive the Deposit and Interest accrued thereon from the Escrow Agent, in accordance with the terms and provisions of Section 3.2 hereof, as its sole and exclusive remedy and thereupon this Agreement shall be terminated and neither Seller nor Purchaser shall have any further rights or obligations hereunder except with respect to the Surviving Termination Obligations. The amount of the Deposit and Interest accrued thereon shall be the full, agreed and liquidated damages for Purchaser’s default and failure to complete the purchase of the Property, all other claims to damages or other remedies being hereby expressly waived by Seller. Notwithstanding the foregoing, from and after the Closing, nothing contained herein shall limit Seller’s remedies at law or in equity as to the Surviving Termination Obligations.

ARTICLE XIII.

ARTICLE XIV.

Publication

14.1. Publication. Purchaser and Seller acknowledge that upon execution of this Agreement and at Closing, the parties shall issue a press release in form and substance reasonably agreed to by the parties hereto; provided nothing herein shall restrict either party from issuing a press release to the extent required by law or requirements of the Securities and Exchange Commission. In addition, Purchaser and Seller shall consult with each other prior to making any public statements with respect to this Agreement and the transactions contemplated hereby, and except as otherwise may be required by law or as otherwise set forth in this Section 14.1, Purchaser and Seller shall not make any public statements, including, without limitation, any press releases, with respect to this Agreement and the transactions contemplated hereby, without the prior written consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed.

16.2. Governing Law; Venue.

16.2.1. This Agreement was negotiated in the State of New York and was executed and delivered by Seller and Purchaser in the State of New York, which State the parties agree has a substantial relationship to the parties and to the underlying transactions embodied hereby, and in all respects, including, without limiting the generality of the foregoing, matters of construction, validity, enforcement and performance, this Agreement and the obligations arising hereunder shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and performed wholly within such State, without giving effect to the principles of conflicts of law of such jurisdiction. To the fullest extent permitted by law, the parties hereby unconditionally and irrevocably waive and release any claim that the law of any other jurisdiction governs this Agreement and this Agreement shall be governed and construed in accordance with the laws of the State of New York as aforesaid pursuant to Section 5-1401 of the New York General Obligations Law.

16.2.2. To the maximum extent permitted by applicable law, any legal suit, action or proceeding against any of the parties hereto arising out of or relating to this Agreement shall be instituted in any federal or state court in New York, New York, pursuant to Section 5-1402 of the New York General Obligations Law, and each party hereby irrevocably submits to the exclusive jurisdiction of any such court in any such suit, action or proceeding. Each party hereby agrees to venue in such courts and hereby waives, to the fullest extent permitted by law, any claim that any such action or proceeding was brought in an inconvenient forum.

16.3. Headings. The captions and headings herein are for convenience and reference only and in no way define or limit the scope or content of this Agreement or in any way affect its provisions.

16.4. Business Days. If any date herein set forth for the performance of any obligations of Seller or Purchaser or for the delivery of any instrument or notice as herein provided should be on a Saturday, Sunday or legal holiday, the compliance with such obligations or delivery shall be deemed acceptable on the next business day following such Saturday, Sunday or legal holiday. As used herein, the term “legal holiday” means any state or Federal holiday for which financial institutions or post offices are generally closed in the State of New York.

16.5. Counterpart Copies. This Agreement may be executed in two or more counterpart copies, all of which counterparts shall have the same force and effect as if all parties hereto had executed a single copy of this Agreement.

16.6. Binding Effect. This Agreement shall not become a binding obligation upon Seller or Purchaser unless and until the same has been fully executed by Purchaser and Seller and a fully executed counterpart has been delivered by Seller to Purchaser

16.7. Successors and Assigns. This Agreement shall be binding upon, and inure to the benefit of, the parties hereto and their respective successors and permitted assigns.

16.8. Assignment. Purchaser represents that the beneficial owner of Purchaser as of the date hereof is Allan V. Rose. This Agreement may not be assigned by either party except to

an affiliated entity under common control with Purchaser or a wholly-owned subsidiary or subsidiaries of Purchaser (any such entity, a “Permitted Assignee”) and any other assignment or attempted assignment by Purchaser shall constitute a default hereunder and shall be deemed null and void and of no force or effect. A transfer of 50% or more of the beneficial ownership interests of Purchaser shall constitute an assignment of this Agreement provided that the nothing herein shall limit a transfer of up to 50% of the beneficial ownership interests of Purchaser provided such transfers do not, individually or collectively, have an adverse effect on the approval process under the Ground Lease (it being agreed that any transfer of beneficial interests in Purchaser of less than five percent (5%) shall be permitted in accordance with the terms of the Ground Lease). A copy of any assignment permitted hereunder, together with an agreement of the assignee assuming all of the terms and conditions of this Agreement to be performed by Purchaser in form reasonably satisfactory to counsel for Seller, shall be delivered to the attorneys for Seller prior to the Closing, and in any event no such assignment shall relieve Purchaser from the obligations under this Agreement nor result in a delay in the Closing. In the event Purchaser assigns this Agreement to a Permitted Assignee, all representations and warranties and covenants and obligations of Purchaser hereunder shall apply with equal force to such Permitted Assignee. Notwithstanding anything to the contrary in this Section 16.8, no assignment of this Agreement shall be permitted if such assignment would require a resubmission or supplement to a submission under Section 8.13.1 hereof.

16.9. Interpretation. This Agreement shall not be construed more strictly against one party than against the other merely by virtue of the fact that it may have been prepared by counsel for one of the parties, it being recognized that both Seller and Purchaser have contributed substantially and materially to the preparation of this Agreement.

16.10. Entire Agreement. This Agreement and the Exhibits and Schedules attached hereto contain the final and entire agreement between the parties hereto with respect to the sale and purchase of the Property and are intended to be an integration of all prior negotiations and understandings. Purchaser, Seller and their respective agents shall not be bound by any terms, conditions, statements, warranties or representations, oral or written, not contained herein. No change or modifications to this Agreement shall be valid unless the same is in writing and signed by the parties hereto. Each party reserves the right to waive any of the terms or conditions of this Agreement which are for their respective benefit and to consummate the transactions contemplated by this Agreement in accordance with the terms and conditions of this Agreement which have not been so waived. Any such waiver must be in writing signed by the party for whose benefit the provision is being waived.

16.11. Severability. If any one or more of the provisions hereof shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision hereof, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein, unless and to the extent that the invalidation of any such term or provision materially alters the intent of the parties hereto.

16.12. Survival. Except for those provisions of this Agreement which expressly provide that any obligation, representation, warranty or covenant contained therein shall survive the Closing or the termination of this Agreement (collectively, the “Surviving Termination

Obligations”), the provisions of this Agreement and the representations and warranties herein shall not survive after the conveyance of title and payment of the Balance of the Purchase Price but be merged therein.

16.13. Exhibits. Each of the Exhibits and Schedules attached hereto are incorporated herein by reference.

16.14. Limitation of Liability. The obligations of Seller and Purchaser are intended to be binding only on Seller and Purchaser and each of such party’s assets (including, with respect to Purchaser, the Deposit), and shall not be personally binding upon, nor shall any resort be had to, any of the members, partners, officers, directors, shareholders, advisors, trustees, agents, or employees of Seller or Purchaser, or any of their respective affiliates or any of their respective properties.

The respective parties hereto shall and hereby do waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other on any matters whatsoever arising out of or in any way connected with this Agreement, or for the enforcement of any remedy under any statute, emergency or otherwise.

16.20. Cooperation. (a) Seller shall have the right to structure the sale of the Property as a forward or reverse exchange thereof for other real property of a like-kind to be designated by Seller (including the ability to assign this Agreement to an entity established in order to

effectuate such exchange), with the result that the exchange shall qualify for non-recognition of gain or loss under Section 1031 of the Internal Revenue Code of 1986, as amended, in which case Purchaser shall execute any and all documents reasonably necessary to effect such exchange, as reasonably approved by Purchaser’s counsel, and otherwise assist and cooperate with Seller in effecting such exchange, provided that: (i) any costs and expenses incurred by Purchaser as a result of structuring such transaction as an exchange, as opposed to an outright sale, shall be borne by Seller; (ii) Seller shall indemnify and hold harmless Purchaser from and against any and all liabilities, costs, damages, claims or demands arising from the cooperation of Purchaser in effecting the exchange contemplated hereby; and (iii) such exchange shall not result in any delay in closing the transaction without Purchaser’s prior written consent. Seller, in its discretion, may adjourn the Closing Date for up to thirty (30) days in the aggregate in order to effect such exchange provided that in no event shall Seller have the right to extend the Closing Date beyond April 29, 2007.

(b) Purchaser shall have the right to structure the sale of the Property as a forward or reverse exchange thereof for other real property of a like-kind to be designated by Purchaser (including the ability to assign this Agreement to an entity established in order to effectuate such exchange), with the result that the exchange shall qualify for non-recognition of gain or loss under Section 1031 of the Internal Revenue Code of 1986, as amended, in which case Seller shall execute any and all documents reasonably necessary to effect such exchange, as reasonably approved by Seller’s counsel, and otherwise assist and cooperate with Purchaser in effecting such exchange, provided that: (i) any costs and expenses incurred by Seller as a result of structuring such transaction as an exchange, as opposed to an outright sale, shall be borne by Purchaser; (ii) Purchaser shall indemnify and hold harmless Seller from and against any and all liabilities, costs, damages, claims or demands arising from the cooperation of Seller in effecting the exchange contemplated hereby; and (iii) such exchange shall not result in any delay in closing the transaction without Seller’s prior written consent. Purchaser, in its discretion, may adjourn the Closing Date for up to thirty (30) days in the aggregate in order to effect such exchange provided that in no event shall Purchaser have the right to extend the Closing Date beyond April 29, 2007.

ARTICLE V.

Closing, Adjustments and Closing Costs

5.1. Closing. The closing of the sale of the Receivables and the Trademark (the “Closing”) shall be held at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, Four Times Square, New York, New York, 10036, or, at Purchaser’s election, at the New York office of the counsel for Purchaser’s lender, at 10:00 a.m. local time on February 28, 2007 (the “Scheduled Closing Date”); provided, however, that the Scheduled Closing Date shall be automatically adjourned if, and to the same date that, the “Scheduled Closing Date” under the Site Purchase and Sale Agreement is adjourned.

5.2. Adjustments to ESAC Receivables.

5.2.1. Except as otherwise set forth in this Agreement, there shall be no prorations, credits or adjustments made in connection with the Closing.

5.2.2. Seller shall have the right to apply up to $9,050,000 of the existing ESAC Receivables towards the payment of the Transaction Payment (as defined in the Ground Lease) required to be paid by Seller under the Site Purchase and Sale Agreement or in connection with this Agreement, and without adjustment to the Purchase Price hereunder.

5.2.3. Seller shall have the right to apply ESAC Receivables and Site 6 Receivables towards the payment of amounts due and owing under the Ground Lease, in accordance with the terms and conditions of the Ground Lease, and without adjustment to the Purchase Price hereunder.

5.2.4. The Purchase Price shall not be increased as a result of the accrual of any interest under the LADA on the Receivables between the date hereof and the Closing Date.

5.2.5. The provisions of this Section 5.2 shall survive the Closing.

5.3. Transfer Taxes. Any state or city transfer taxes payable in connection with the Closing shall be paid by the Seller. Notwithstanding the foregoing, it is the parties’ view that the subject matter of this Agreement (i.e., the Receivables and the Trademark) are “intangibles” or “receivables” and are not “interests in real property” and that accordingly, no real estate transfer taxes should be payable in connection with the Closing. Seller and Purchaser each agrees that it will not take a position, in any transfer tax filing with New York City or New York State, contrary to that expressed in the prior sentence, unless such party is advised by independent legal counsel (experienced in the matter in question) that such party may not lawfully continue to maintain such position, in which event, such party shall nevertheless consult with the other party prior to taking such contrary position. Seller shall indemnify and hold harmless Purchaser from an against any and all claims and liabilities, including reasonable attorneys’ fees, associated with any transfer taxes which may be due as a result of the transfer of the Receivables and/or the Trademark.

5.4. Closing Costs.

5.4.1. Purchaser shall pay all recording fees and charges associated with the recordation of the ESAC Assignment and the Site 6 Receivable Assignment. All other costs, fees, expenses and charges of any kind incident to the sale and conveyance of the Receivables from Seller to Purchaser, including attorneys’ fees and consultants’ fees, shall be borne by the party incurring the same.

Mayer, Senior Vice President of Boston Properties, Inc., and (ii) Robert Selsam, Senior Vice President of Boston Properties, Inc., only, and not any implied, imputed or constructive knowledge of Robert Selsam or any other party, without any independent investigation having been made or any implied duty to investigate.

6.3. Survival. The express representations and warranties made in this Agreement by Seller shall not merge into any instrument of conveyance delivered at the Closing and all of the representations and warranties made in this Agreement by Seller shall survive the Closing for a period of twelve (12) months (the “Survival Period”); provided, however, that any action, suit or proceeding with respect to the truth, accuracy or completeness of such representations and warranties shall be commenced, if at all, on or before the date which is twelve (12) months after the date of the Closing and, if not commenced on or before such date, thereafter shall be void and of no force or effect. The terms and provisions of this Section 6.3 shall survive the Closing.

6.4. Relationship Between Representations and Estoppels. To the extent that any representation or warranty made by Seller herein is confirmed by one or more estoppels delivered by the party or parties who would otherwise have the right to assert a claim or raise a defense with respect to the matters set forth therein, Seller shall be relieved of any liability in respect of such representation or warranty. The terms of this Section 6.4 shall survive the Closing.

7.4. Purchaser’s Agreement Regarding Seller’s Representations. Purchaser agrees that in the event that Purchaser shall obtain knowledge of any information that is contradictory to, and would constitute the basis of a breach of, any representation or warranty or failure to satisfy any condition on the part of Seller, then Purchaser shall promptly deliver Seller written notice of such information specifying the representation, warranty or condition to which such information relates.

7.5. NO OTHER REPRESENTATIONS OR WARRANTIES; AS IS. EXCEPT AS EXPRESSLY SET FORTH HEREIN OR IN ANY OF THE RELATED AGREEMENTS, PURCHASER HAS AGREED TO PURCHASE THE RECEIVABLES ON THE CLOSING DATE ON AN “AS IS, WHERE IS BASIS, WITH ALL FAULTS,” WITH NO RIGHT OF SET-OFF OR REDUCTION IN THE PURCHASE PRICE. EXCEPT AS MAY BE EXPRESSLY SET FORTH HEREIN OR IN ANY OF THE RELATED AGREEMENTS, SUCH PURCHASE SHALL BE WITHOUT REPRESENTATION OR WARRANTY, OR

RECOURSE, OF ANY KIND, EXPRESS OR IMPLIED (INCLUDING ANY REPRESENTATION, WARRANTY OR RECOURSE OF OR WITH RESPECT TO TITLE, COLLECTIBILITY, THE LIKELY TIMING OF RECEIPT OF THE RECEIVABLES OR THE MARKETABILITY OF THE RECEIVABLES), AND SELLER DOES HEREBY DISCLAIM AND RENOUNCE ANY SUCH REPRESENTATION OR WARRANTY. PURCHASER ACKNOWLEDGES THAT THE VALUE OF THE RECEIVABLES IS DEPENDENT ON THE FOLLOWING FACTORS, AMONG OTHERS, (I) THE RELATIONSHIP BETWEEN MARKET RATES OF INTEREST AND THE INTEREST RATE PAYABLE AS INTEREST IN RESPECT OF THE RECEIVABLES, (II) THE TIMING OF THE RECEIPT OF PAYMENTS IN RESPECT OF THE RECEIVABLES, AND (III) THE CONTINUANCE OF THE GROUND LEASE, ON WHICH THE PAYMENT OF AMOUNTS CONSTITUTING RECEIVABLES IS DEPENDENT. PURCHASER AND EXPERTS OF PURCHASER’S CHOICE HAVE (I) DETERMINED THE FAIR MARKET VALUE OF THE RECEIVABLES, SUBJECT TO THE TERMS AND CONDITIONS OF THIS AGREEMENT, (II) ANALYZED THE PRESENT AND PROJECTED VALUE OF, AND THE POTENTIAL TIMING AND AMOUNT OF RECEIPTS TO BE PAID FROM, THE RECEIVABLES AND (III) INDEPENDENTLY VERIFIED THE COMPLETENESS AND ACCURACY OF ALL DOCUMENTS AND INFORMATION PROVIDED BY SELLER AND/OR ITS AGENTS WHICH PURCHASER DEEMS NECESSARY OR MATERIAL TO CLOSE THE PURCHASE OF THE RECEIVABLES. PURCHASER ACKNOWLEDGES IT IS A SOPHISTICATED INVESTOR, HAS RETAINED COMPETENT COUNSEL AND FINANCIAL ADVISORS AND HAS BEEN GIVEN AMPLE TIME FOR IT (AND ITS COUNSEL AND ADVISORS) TO CONDUCT DUE DILIGENCE IN CONNECTION WITH THIS TRANSACTION AND ANALYZE THE SAME. PURCHASER IS NOT RELYING UPON ANY REPRESENTATION, INDUCEMENT OR UNPERFORMED PROMISE OF SELLER OR SELLER’S AGENTS EXCEPT TO THE EXTENT SUCH INDUCEMENT, REPRESENTATION OR UNPERFORMED PROMISE IS EXPRESSLY SET FORTH HEREIN OR IN THE RELATED AGREEMENTS. EXCEPT AS AFORESAID, PURCHASER IS RELYING ON ITS OWN INSPECTION AND ANALYSIS OF THE PROJECT DOCUMENTS AND ITS OWN DEVELOPMENT PLANS IN REACHING ITS DECISION TO PURCHASE THE RECEIVABLES, AND PURCHASER IS NOT RELYING UPON ANY ANALYSES OR SUMMARIES OR PROJECTIONS PRODUCED BY OR ON BEHALF OF SELLER OR SELLER’S AGENTS. EXCEPT AS EXPRESSLY SET FORTH HEREIN AND IN THE RELATED AGREEMENTS, PURCHASER RELEASES SELLER FROM, AND WAIVES ALL CLAIMS AND LIABILITY AGAINST SELLER FOR, ANY DEFECT IN THE RECEIVABLES, AND SUCH RELEASE AND WAIVER SHALL ALSO COVER ANY CROSS-CLAIM, IMPLEADER OR SIMILAR CLAIM THAT MIGHT BE ASSERTED BY PURCHASER OR ANY OF ITS SUCCESSORS-IN-INTEREST AS A RESULT OF A CLAIM BY ANY OTHER PERSON WITH RESPECT TO THE RECEIVABLES. THE FURNISHING OF ANY MATERIALS, DOCUMENTS, REPORTS OR AGREEMENTS BY OR ON BEHALF OF SELLER SHALL NOT BE INTERPRETED IN ANY MANNER AS A REPRESENTATION OR WARRANTY OF ANY TYPE OR ANY KIND BY SELLER, ANY PARTNER OF SELLER, OR ANY OFFICER, DIRECTOR, EMPLOYEE, AGENT OR OTHER PARTY RELATED IN ANY WAY TO ANY OF THE FOREGOING. PURCHASER ACKNOWLEDGES AND AGREES THAT THE PROVISIONS OF THIS SECTION WERE A MATERIAL FACTOR IN INDUCING SELLER TO ENTER INTO THIS AGREEMENT AND

IN DETERMINING THE PURCHASE PRICE. Purchaser shall be deemed to have acknowledged the matters set forth above in this Section 7.5 on the Closing Date as a condition to Seller’s obligation to close this transaction. The terms of this Section 7.5 shall survive the Closing.

7.6. Information From Seller’s Agents. Subsequent to the date of this Agreement, Purchaser may request from Seller’s agents (i.e., advisors, on-site property manager, contractors or similar individuals or entities engaged by Seller and/or its affiliates relating to or involving the Site) information or opinions regarding the Receivables or some aspect of the Receivables, their history, condition or prospects for future use by Purchaser. Purchaser has been informed that Seller’s files may not be complete. While Seller is willing to cooperate with Purchaser, and Seller has instructed its agents to cooperate with Purchaser, SELLER IS UNWILLING TO SELL THE RECEIVABLES UNLESS SELLER IS FULLY RELEASED BY PURCHASER IN THE MANNER SET FORTH IN THE IMMEDIATELY FOLLOWING SENTENCE. IN CONSIDERATION FOR SELLER’S AGREEMENT TO SELL THE RECEIVABLES TO PURCHASER ON THE TERMS AND CONDITIONS HEREIN SET FORTH, PURCHASER AGREES THAT IT SHALL RELEASE SELLER, FOR (i) STATEMENTS OR OPINIONS MADE, OR INFORMATION FURNISHED, BY SELLER OR SELLER’S AGENTS UNLESS SUCH STATEMENTS, OPINIONS OR INFORMATION IS EXPRESSLY INCORPORATED HEREIN OR IN ANY OTHER RELATED AGREEMENT OR IN ANY DOCUMENT THAT MAY HEREAFTER BE ENTERED INTO AS SELLER REPRESENTATIONS OR (ii) INFORMATION WITHHELD BY SELLER’S AGENTS AND NOT OTHERWISE MADE KNOWN TO PURCHASER, UNLESS (A) SUCH INFORMATION WOULD HAVE BEEN MATERIAL TO AND ADVERSELY AFFECTED PURCHASER’S DECISION TO ENTER INTO THIS AGREEMENT AND (B) THE FACT THAT SUCH INFORMATION WAS WITHHELD WAS ACTUALLY KNOWN TO SELLER OR ITS LEGAL COUNSEL. NOTHING IN THE PRECEDING SENTENCE SHALL BE CONSTRUED TO CREATE LIABILITY ON THE PART OF SELLER WHERE SUCH LIABILITY WOULD NOT OTHERWISE EXIST HEREUNDER OR AT LAW OR EQUITY.

ARTICLE VIII.

Default

12.1. Default by Seller.

(a) In the event the Closing and the transactions contemplated hereby do not occur as provided herein by reason of a default of Seller, Purchaser may elect, as the sole and exclusive remedy of Purchaser, to (i) terminate this Agreement and receive the Deposit and Interest from the Escrow Agent in accordance with the terms and provisions of Section 3.2 hereof, and in such event Seller shall not have any liability whatsoever to Purchaser hereunder other than with respect to the Surviving Termination Obligations, or (ii) enforce specific performance of this Agreement.

12.2. Default by Purchaser. In the event the Closing and the transactions contemplated hereby do not occur on or before the Closing Date as provided herein by reason of any default of Purchaser, Purchaser and Seller agree it would be impractical and extremely difficult to fix the damages which Seller may suffer. Therefore, Purchaser and Seller hereby agree a reasonable estimate of the total net detriment Seller would suffer in the event Purchaser defaults and fails to complete the purchase of the Receivables is and shall be, as Seller’s sole and exclusive remedy (whether at law or in equity), a sum equal to the Deposit and Interest accrued thereon.

The amount of the Deposit and Interest accrued thereon shall be the full, agreed and liquidated damages for Purchaser’s default and failure to complete the purchase of the Receivables, all other claims to damages or other remedies being hereby expressly waived by Seller. Notwithstanding the foregoing, from and after the Closing, nothing contained herein shall limit Seller’s remedies at law or in equity as to the Surviving Termination Obligations.

15.8. Assignment. This Agreement may not be assigned by Purchaser except to a wholly-owned subsidiary or subsidiaries of Purchaser (any such entity, a “Permitted Assignee”) and any other assignment or attempted assignment by Purchaser shall constitute a default by Purchaser hereunder and shall be deemed null and void and of no force or effect.

BOSTON PROPERTIES, INC.

PRO FORMA CONSOLIDATED BALANCE SHEET

INTRODUCTION TO THE PRO FORMA CONSOLIDATED BALANCE SHEET

September 30, 2006

(Unaudited)

The accompanying unaudited Pro Forma Consolidated Balance Sheet of Boston Properties, Inc. (the “Company”) is presented as if the disposition of the long-term leasehold interest in 5 Times Square and related credits, which occurred on February 15, 2007, had been consummated on September 30, 2006. The Company completed the sale of the long-term leasehold interest in 5 Times Square and related credits for a gross sales price of approximately $1.28 billion in cash. 5 Times Square is a Class A office property with approximately 1,101,779 net rentable square feet located in New York City. In conjunction with the sale, the Company has agreed to provide to the buyer monthly revenue support from the closing date until December 31, 2008. The aggregate amount of the revenue support payments will be approximately $1.9 million.

In addition, on January 30, 2007, the Company paid a special cash dividend of $5.40 per common share to shareholders of record as of the close of business on December 29, 2006. The decision to pay a special cash dividend was the result of the sales of assets in 2006, including 280 Park Avenue, which sale was reported on Form 8-K dated June 6, 2006. Holders of common units of limited partnership interest in Boston Properties Limited Partnership, the Company’s Operating Partnership, as of the close of business on December 29, 2006 received the same total distribution on January 30, 2007. Holders of Series Two Preferred Units of limited partnership interest will participate in the special cash dividend on an as-converted basis in connection with their regular May 2007 distribution payment as provided in the Operating Partnership’s partnership agreement. The Company has reflected the payment of the special cash dividend under “Other Adjustments” within the accompanying unaudited Pro Forma Consolidated Balance Sheet.

Such pro forma information is based on the historical consolidated balance sheet of the Company as of that date, giving effect to the disposition of the long-term leasehold interest in 5 Times Square and related credits and the payment of the special cash dividend. This unaudited Pro Forma Consolidated financial information should be read in conjunction with Form 10-Q for the nine months ended September 30, 2006 (unaudited). In management’s opinion, all adjustments necessary to reflect the above transactions have been made.

The following unaudited Pro Forma Consolidated Balance Sheet is not necessarily indicative of what the actual financial position would have been assuming the disposition of the long-term leasehold interest in 5 Times Square and related credits and the payment of the special cash dividend had been consummated on September 30, 2006, nor does it purport to represent the future financial position of the Company.
