Item 1.01.

Entry into a Material Definitive Agreement.

On September 16, 2014, Boston Properties Limited Partnership (the “Company”), a Delaware limited partnership and the entity through which Boston Properties, Inc. conducts substantially all of its business, entered into a binding purchase and sale agreement (the “Purchase and Sale Agreement”) with affiliates of Norges Bank Investment Management (the “Purchasers”) to sell a 45% interest in each of 601 Lexington Avenue in New York City and Atlantic Wharf Office Building and 100 Federal Street in Boston to the Purchasers for an aggregate gross sales price of approximately $1.5 billion in cash.

601 Lexington Avenue is a 1,669,000 square foot Class A office complex located in the heart of Midtown Manhattan at East 53^rd Street and Lexington Avenue. The property consists of a 59-story tower as well as a six-story low-rise office and retail building. The complex is currently 99% leased and subject to existing mortgage indebtedness of approximately $714 million.

The Atlantic Wharf Office Building is a 791,000 square foot Class A office tower located on Boston’s Waterfront with frontage on both the Rose Kennedy Greenway and historic Boston Harbor. This 31-story office building was developed by the Company and completed in 2011, and it is currently 100% leased. This property is unencumbered by debt.

100 Federal Street is a 1,323,000 square foot Class A office tower located in the heart of Boston’s Financial District. The Company acquired this building in 2012, and it is currently 91% leased. This property is unencumbered by debt.

The Company and the Purchasers will form a joint venture for each property upon closing, and the Company will retain property and leasing management for the joint ventures. The agreed-upon sale price is $1.827 billion in cash, less the Purchasers’ pro rata share of the indebtedness secured by 601 Lexington Avenue, which will remain outstanding, subject to certain prorations and adjustments. In connection with the Purchase and Sale Agreement, the Purchasers made a deposit of approximately $45.1 million that will be credited to the sale price at closing, or, if the closing does not occur for any reason other than a default by the Purchasers, will be refunded to the Purchasers. If the closing does not occur due to a default by the Purchasers, then the deposit will serve as liquidated damages for the Company. The closing is subject to customary closing conditions, including the condition that the 45% interest in each of the three properties described above must be sold to the Purchasers at the closing, and there can be no assurance that the sale will be completed on the terms currently contemplated or at all.

Assuming the closing occurs as contemplated, the Company currently expects that it would distribute at least the amount of proceeds necessary to avoid paying a corporate level tax on the gain realized from the sale.

Following the closing, the Company and Boston Properties, Inc. will continue to include all of the assets and liabilities and results of operations of the properties owned by the joint ventures in their consolidated financial statements, and the Purchasers’ interests will be reflected as noncontrolling interests.

The foregoing summary of the Purchase and Sale Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Purchase and Sale Agreement, which is included as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Private Securities Litigation Reform Act of 1995. This Current Report on Form 8-K contains forward-looking statements within the meaning of the federal securities laws. You can identify these statements by our use of the words “guidance,” “expects,” “plans,” “estimates,” “projects,” “intends,” “believes” and similar expressions that do not relate to historical matters.

These factors include, without limitation, the Company’s ability to satisfy the closing conditions to the transaction described above, the Purchasers’ performance of their obligations under the Purchase and Sale Agreement and other risks and uncertainties detailed from time to time in the Company’s filings with the Securities and Exchange Commission. The Company does not undertake a duty to update or revise any forward-looking statement whether as a result of new information, future events or otherwise.

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.

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.

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.

4.2.1 Property Taxes. Real estate and 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.

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 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 4.2.12 hereof. Any discount received for an early payment shall be for the benefit of Seller.

4.2.2 [Condominium Charges. [“Common Charges” or “Limited Common Charges”] paid or payable by Owner pursuant to the [Condominium Declaration] on the basis of the current billing period on a per diem basis based upon the number of days in the current billing period prior to the Closing Date (which shall be allocated to Seller) and the number of days in the current billing period on or after the Closing Date (which shall be allocated to Owner).] [if applicable]

4.2.3 Insurance Premiums. Insurance premiums paid or payable by Owner.

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 Owner before Closing, if possible, or shall be paid thereafter by Owner 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 reimburse Seller for Purchaser’s proportionate share of all deposits, if any, previously furnished by Owner to any utility company or other service provider which are retained (as deposits) 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 Owner 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, as the sole owner of Holdco for the period prior to Closing and Seller and Purchaser in accordance with their respective interests under the JV Agreement for the period after Closing, for the billing period in progress on the Closing Date, based upon the number of days during the accounting period in which the Closing occurs, (ii) second, to any current sums and arrearages owed to Owner (relating to billing periods after the billing period in progress as of the Closing Date), and (iii) last to Seller for all periods prior to the month in which the Closing occurred. Notwithstanding the foregoing, if any Fixed Rent is collected by Owner after the Closing Date which is expressly attributable in whole or in part to any period prior to the Closing, then Seller and Purchaser shall cause Owner to promptly pay to Seller its proportionate share thereof. 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, or in the name of Owner, 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, Seller shall (i) first deliver prior written notice to Purchaser of its intention to pursue such tenants, and (ii) not pursue the eviction of any such tenant or place a lien on or against the Property, without Purchaser’s prior written consent, which consent shall be granted in Purchaser’s sole and absolute discretion, and in which event all sums collected by Owner as a result of such action or proceeding (after payment of all reasonable costs and expenses of collection) shall be allocated to Seller and 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 and Seller each agree to cause Owner to use commercially reasonable efforts to collect any such delinquent rents allocable to the period of Seller’s 100% ownership of Holdco 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 Owner as a result of such litigation (after payment of all costs and expenses, including reasonable attorneys’ fees) shall be allocated to Seller and applied in full satisfaction of the subject delinquencies. 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.

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, 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 Owner Seller’s proportionate share of the amount of such adjustment (after which Owner 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) Seller and Purchaser agree to cause Owner, with respect to such adjustments which are in favor of landlord, to pay to Seller its proportionate share of the amount of such adjustments which the Tenant pays to Owner, within fifteen (15) days after receipt thereof by Owner. Seller and Purchaser agree to cause Owner to, in accordance with Owner’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 Owner 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, or in the name of Owner, 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, Seller and Purchaser agree to cause Owner to use commercially reasonable efforts to collect any such delinquent Additional Rent allocable to the period of Seller’s 100% ownership of Holdco 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 Seller as a result of such litigation (after payment of all costs and expenses) shall be applied in full satisfaction of the subject delinquencies). 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.

(b) With respect to any Tenant which has paid all Additional Rents due and payable to the Closing Date, if, prior to the Closing, Owner or Owner’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 Seller shall cause Owner to retain such amounts until Closing.

(c) Any Additional Rents collected by Owner 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 Seller, as the sole owner of Holdco for the period prior to Closing and Seller and Purchaser in accordance with their respective interests under the JV Agreement for the period after Closing, based upon the number of days 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 in which the Closing occurs. Notwithstanding the foregoing, (I) if any Additional Rents are collected by Owner after the Closing Date which are expressly attributable in whole or in part to any period prior to the Closing, then Seller and Purchaser shall cause Owner to promptly pay to Seller its proportionate share thereof, (II) if any Additional Rents are collected by Owner after the Closing Date which are expressly attributable in whole or in part to any period prior to the Closing, then Owner may retain its proportionate share thereof, and (III) any funds collected by Owner 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, as the sole owner of Holdco for the period prior to Closing and Seller and Purchaser in accordance with their respective interests under the JV Agreement for the period after Closing.

(d) Any rents or other amounts paid by Tenants pursuant to the Leases actually received and collected by Owner 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.

Seller shall reimburse Purchaser as an adjustment item to the extent Owner has not paid

any Leasing Commissions prior to the Closing which are the responsibility of Seller under this Section 4.2.7 and Purchaser and Seller shall cause Owner to reimburse Seller as an adjustment item to the extent Seller has paid any Leasing Commissions prior to Closing which are the responsibility of Owner under this Section 4.2.7.

Seller represents and warrants, except as set forth on Schedule 4.2.7(b), that as of the date hereof, there are no other Tenant Allowances payable in connection with the Existing Leases. Notwithstanding anything to the contrary in this Section 4.2.7(b), to the extent any matter specified in Schedule 4.2.7(b) is inconsistent with the foregoing provisions of this Section 4.2.7(b), Schedule 4.2.7(b) shall govern.

(a) Purchaser shall have no right to object to any title or survey matters which are Permitted Exceptions (as hereinafter defined). If any update of either the Survey or the Title Commitment shall reveal or disclose any defects, objections or exceptions in the title to the Real Property which are not Permitted Exceptions 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 of such updated Title Commitment or update of the Survey.

(b) 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 updated Title Commitment and updated Survey 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. At the Closing, the Property shall be subject only to the Permitted Exceptions.

(a) Permitted Exceptions to Title. At Closing, title to the Property shall be held by Owner subject only to the following exceptions to title (the “Permitted Exceptions”):

(12) any other matter or thing affecting title to the Property that Purchaser shall have agreed or be deemed to have agreed to waive.

5.1.4 Elimination of Liens. If any Title Objections appear in any update to the Title Commitment or the Survey which are not Permitted Exceptions and to which Purchaser has timely objected pursuant to Section 5.1.2 hereof, then Seller shall be obligated to cause to be released, satisfied and otherwise discharged of record all such Title Objections which are (1) a mortgage, deed of trust, security agreement, financing statement, or any other instrument which evidences or secures indebtedness, a mechanics’ lien, or any other lien which can be satisfied by the payment of a liquidated sum but expressly excluding any liens caused by the act or failure to act of a Tenant or with respect to which the responsibility to pay, discharge or bond over is that of a Tenant[, and further excluding any instruments relating to the Existing Mortgage Loan] (collectively, “Monetary Encumbrances”), and (2) any encumbrances voluntarily recorded or otherwise placed or permitted to be placed by Seller or Owner against the Property on or following the date of the Title Commitment and not approved by Purchaser (“Voluntary Encumbrances”). Nothing herein shall require Seller or Owner to cure any title objection other than as expressly set forth in the immediately preceding sentence. Either Seller or Purchaser, each in its sole discretion, may adjourn the Scheduled Closing Date from time to time for up to one hundred eighty (180) days in the aggregate, during which period Seller shall use commercially reasonable efforts to eliminate any Title Objections or Voluntary Encumbrances (which in either case are not Permitted Exceptions). 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 each party’s right to adjourn the Scheduled Closing Date for up to one hundred eighty (180) days 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, neither party shall have any obligations hereunder except those expressly stated to survive the termination of this Agreement, and if the sole reason for Purchaser’s termination is Seller’s failure to remove a Voluntary Encumbrance against the Property, Purchaser shall be entitled to a reimbursement from Seller up to an amount not to exceed Dollars ($ ), for the reasonable costs and expenses actually incurred by Purchaser in connection with Purchaser’s negotiation and execution of this Agreement and due diligence with respect to the Property, 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 the amount necessary to discharge of record all of the unsatisfied Monetary Encumbrances. Seller agrees that Seller shall not and shall not cause Owner to 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, together with the cost of recording or filing any instruments necessary to discharge such Monetary Encumbrances, may be paid out of the proceeds of the Balance of the Purchase Price payable at the Closing. Seller hereby agrees to deliver to the Title Company, on the Closing Date, instruments in recordable form sufficient to discharge any such Monetary Encumbrances 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 Title Commitment discloses judgments, bankruptcies or other returns against other persons having names the same as or similar to that of Seller or Owner, Seller, on request, shall deliver to the Title Company affidavits showing that such judgments, bankruptcies or other returns are not against Seller or Owner (as applicable), in form reasonably acceptable to the Title Company and to Seller.

Purchaser hereby acknowledges and agrees that at Closing, the Property may be 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. Neither Seller nor Owner shall have any 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, neither Seller nor Owner shall have any duty to remove or comply with or repair any of the aforementioned Violations, or other conditions, and Purchaser hereby acknowledges and agrees that it shall accept the Membership Interests with 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, and that in each case, Purchaser shall purchase the Membership Interests without any abatement of or credit against the Purchase Price with respect thereto; provided, however, that with respect to any Violations first arising after the date of this Agreement but prior to Closing, Seller shall, at its sole cost and expense, cure such Violations, which obligation shall survive the Closing.

Expressly excluding the representations contained in Section 6.1.10 and 6.1.15 hereof and any representations and warranties set forth in any estoppel certificate delivered by Seller in lieu of any one of the Required Estoppel Certificates pursuant to Section 8.12.3 below, 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 until the later to occur of (a) June 1, 2016 or (b) the date which is eighteen (18) months following the Closing Date (the “Survival Period”); provided, however, that any action, suit or proceeding with respect to the truth, accuracy or completeness of such representations and warranties

(excluding the representations contained in Section 6.1.10 and 6.1.15 hereof and any representations and warranties set forth in any estoppel certificate delivered by Seller in lieu of any one of the Required Estoppel Certificates pursuant to Section 8.12.3 below) shall be commenced, if at all, on or before the expiration of the Survival Period and, if not commenced on or before such date, thereafter shall be void and of no force or effect.

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, expressly excluding the representations contained in Section 6.1.10 and 6.1.15 hereof and any representations and warranties set forth in any estoppel certificate delivered by Seller in lieu of any one of the Required Estoppel Certificates pursuant to Section 8.12.3 below, (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 Section 6.1 hereof and/or under any of the certificates of Seller updating such representations and warranties set forth in or delivered pursuant to this Agreement, if the same in the aggregate shall have a monetary value (or be in a monetary amount claimed) of less than One Hundred Fifty Thousand Dollars ($150,000) (the “Threshold Amount”) (provided that if such claims exceed the Threshold Amount, then Seller shall be liable for the entire amount of the losses, claims, costs or expenses claimed by Purchaser, subject to clause (ii) hereof) and (ii) the aggregate liability of Seller for claims first asserted by Purchaser after the Closing arising pursuant to or in connection with the inaccuracy of any of such representations and warranties of Seller and/or such certificates of Seller set forth in or delivered pursuant to this Agreement shall not exceed Twenty Five Million Dollars ($25,000,000) (the “Liability Cap”). For the avoidance of doubt, Seller’s liability for claims asserted by Purchaser after the Closing arising pursuant to or in connection with the inaccuracy of any of such representations and warranties of Seller and/or such certificates of Seller set forth in or delivered pursuant to this Agreement shall be exclusive of Seller’s liability for claims asserted by Purchaser prior to Closing pursuant to Section 6.6.1 hereof, provided that Purchaser shall be barred from asserting the same claims after the Closing as had been asserted prior to Closing. The terms and provisions of this Section 6.5 shall survive Closing and/or termination of this Agreement. For the avoidance of doubt, the terms of this Section 6.5 shall not apply to Section 6.1.10 and 6.1.15 hereof or any representations and warranties set forth in any estoppel certificate delivered by Seller in lieu of any one of the Required Estoppel Certificates pursuant to Section 8.12.3 below.

6.6 Representations as a Condition to Closing. The representations and warranties set forth herein above and all other representations and warranties contained in this Agreement shall be true and correct in all material respects as of the Closing Date (except to the extent any such representations and warranties expressly relate to an earlier date and with such changes as are permitted under, or result by reason of the effect of, this Agreement); it being agreed, however, that if any of such representations and warranties shall not be true and correct in all material respects as of the Closing Date, the following provisions shall apply:

6.6.1 Any claim by Purchaser of a breach of one or more of Seller’s representations contained in this Agreement prior to or at Closing, including any certificate delivered pursuant to Section 8.12.3, (individually or collectively, as applicable, a “Breach”), shall be made by Purchaser delivering to Seller written notice (a “Claim Notice”) promptly after Purchaser has learned of such Breach and, in all events, prior to the Scheduled Closing Date or the new Scheduled Closing Date (as applicable), which Claim Notice shall set forth (a) a description in reasonable detail of the claimed Breach, (b) the section and subsection of this Agreement under which the claimed Breach is asserted, and (c) Purchaser’s good faith calculation of the diminution in the value of the Membership Interest directly resulting from such Breach (the “Claimed Damage”). Time shall be of the essence in respect of Purchaser’s obligation to deliver to Seller a Claim Notice as, when and in the manner herein provided. As used in Section 6.6.2 below, the term “Material Adverse Effect” means, with respect to any Breach, a diminution in the value of the Membership Interest in an amount that, when added to the diminution in the value of the Membership Interest attributable to all other Breaches, is equal to or greater than the Threshold Amount in the aggregate. Purchaser’s and Seller’s rights and remedies in respect of any alleged Breach shall, without limiting the foregoing, be as herein below provided.

6.6.2 Material Adverse Effect.

(a) If, prior to the Closing, there occurs or exists a Breach which does not have a Material Adverse Effect, then (i) Purchaser shall have no remedy therefor and must proceed to the Closing, and (ii) the Purchase Price shall not be reduced; provided, however, that to the extent Purchaser brings any post-Closing action against Seller in accordance with this Section 6.6, then, notwithstanding anything to the contrary contained herein, the diminution in value of the Membership Interest on account of any such pre-Closing Breach shall be included in the calculation of the Claimed Damage of any such post-Closing Breach for the sole purpose of determining whether or not the Claimed Damages of any such post-Closing Breach in the aggregate exceed the Threshold Amount.

(b) If, prior to the Closing, Purchaser shall assert a Breach that has a Material Adverse Effect (a “Material Breach”), and the Claimed Damage therefor is less than TWENTY FIVE MILLION AND 00/100 DOLLARS ($25,000,000.00), then Purchaser may, as its sole and exclusive remedy (without limiting, however, Purchaser’s right to bring an action for specific performance in accordance with Section 12.1 as the result of a default by Seller), either (A) proceed to close on the purchase of the Membership Interest, in which event (i) the Purchase Price shall be reduced by an amount equal to the Claimed Damage, and (ii) Purchaser shall waive by written notice to Seller (a “Waiver Notice”) any claims against Seller for the Claimed Damage with respect to such Breach (it being understood and agreed that the closing on the purchase of the Membership Interest hereunder under such circumstances shall in and of itself be deemed to constitute such waiver by Purchaser, whether or not such Waiver Notice is actually delivered) or (B) terminate this Agreement by the giving of the Claim Notice, which termination shall be effective upon the expiration of the Termination Nullification Period unless Seller has theretofore given a Termination Nullification Notice. If Purchaser has elected to terminate this

Agreement pursuant to clause (B) above, Purchaser shall receive (i) a full refund of the Deposit and Interest accrued thereon and (ii) reimbursement from Seller up to an amount not to exceed Dollars ($ ), for the reasonable costs and expenses actually incurred by Purchaser in connection with Purchaser’s negotiation and execution of this Agreement and due diligence with respect to the Property; provided, however, that Seller may nullify such termination within ten (10) Business Days of receipt by Seller of a Claim Notice from Purchaser electing to terminate this Agreement (the “Termination Nullification Period”) by (1) delivering to Purchaser a notice nullifying such termination (a “Termination Nullification Notice”) and (2) crediting the Purchase Price in the amount of the Claimed Damage (the “Material Breach Credit”), in which event Purchaser shall be required to close on the purchase of the Membership Interest without adjustment to the Purchase Price under this Section 6.6. Notwithstanding anything contained herein to the contrary, Seller may elect to dispute the amount by which Purchaser asserts the Purchase Price should be reduced or that Purchaser is entitled to terminate this Agreement under this Section 6.6, as applicable, because Seller asserts that either (I) no Breach has occurred or exists, (II) the asserted Breach is not a Material Breach and/or (III) the amount of the Claimed Damage exceeds the actual diminution in the value of the Membership Interest resulting from such Breach (a “Dispute”), delivering a Dispute Notice and depositing with Escrow Agent upon Closing an amount equal to the Material Breach Credit as described in Section 6.6.3 below, in which event Purchaser shall be required to close on the purchase of the Membership Interest without further adjustment of the Purchase Price resulting from such claimed Breach, and such dispute shall be resolved pursuant to Section 6.6.3 below. In the event Purchaser’s Claim Notice is sent less than ten (10) Business Days prior to the Scheduled Closing Date or the new Scheduled Closing Date (as applicable) then the Scheduled Closing Date or the new Scheduled Closing Date (as applicable) shall be automatically extended in order to provide Seller with the entire ten (10) Business Day period during which to send a Termination Nullification Notice.

(c) If, prior to the Closing, Purchaser shall assert a Material Breach, and the Claimed Damage therefor is equal to or greater than TWENTY FIVE MILLION AND 00/100 DOLLARS ($25,000,000.00), then Purchaser may, as its sole and exclusive remedy (without limiting, however, Purchaser’s right to bring an action for specific performance in accordance with Section 12.1 as the result of a default by Seller), either (A) proceed to close on the purchase of the Membership Interest, in which event (i) the Purchase Price shall be reduced by TWENTY FIVE MILLION AND 00/100 DOLLARS ($25,000,000.00), and (ii) Purchaser shall waive by written notice to Seller (a “Waiver Notice”) any claims against Seller for the Claimed Damage with respect to such Breach (it being understood and agreed that the closing on the purchase of the Membership Interest hereunder under such circumstances shall in and of itself be deemed to constitute such waiver by Purchaser, whether or not such Waiver Notice is actually delivered) or (B) terminate this Agreement by the giving of the Claim Notice, which termination shall be effective upon the giving of the Claim Notice (it being understood that Seller shall not be entitled to give a Termination Nullification Notice). If Purchaser has elected to terminate this Agreement pursuant to clause (B) above, Purchaser shall receive (i) a full refund of the Deposit and Interest accrued thereon and (ii) reimbursement from Seller up to an amount not to exceed Dollars ($ ), for the reasonable costs and expenses actually incurred by Purchaser in connection with Purchaser’s negotiation and execution of this Agreement and due diligence with respect to the Property.

6.6.3 If, prior to the Closing, Purchaser serves a Claim Notice asserting a Material Breach and Seller has given a Termination Nullification Notice in accordance with Section 6.6.2, Seller may Dispute such Claim Notice by delivering written notice to Purchaser in the manner herein provided (a “Dispute Notice”). A Dispute Notice shall be given prior to the Closing or within ten (10) Business Days of receipt of a Claim Notice if received more than ten (10) Business Days prior to the Scheduled Closing Date or the new Scheduled Closing Date (as applicable). If Seller has given a Termination Nullification Notice in accordance with Section 6.6.2 but does not deliver a Dispute Notice, then the parties shall proceed with the Closing as described in Article IV and the Purchase Price shall be reduced as provided in Section 6.6.2. If Seller has given a Termination Nullification Notice and delivered a Dispute Notice each in accordance with Section 6.6.2, then Seller shall deposit with Escrow Agent at the Closing an amount equal to the Material Breach Credit (the “Escrow Funds”) to be held in escrow pending a resolution of the Dispute by final court order or as the parties may otherwise agree. Seller may direct that a portion of the Purchase Price to be paid at Closing be paid to Escrow Agent to serve as the Escrow Funds. Provided Seller has deposited the Escrow Funds with Escrow Agent pending resolution of the Dispute as hereinabove provided, Purchaser shall be required to close title to the Premises without adjustment of the Purchase Price on account of the Breach in Dispute.

6.6.4 The Dispute as set forth in a Dispute Notice shall be resolved by expedited arbitration (the “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 and initiate the Arbitration within five (5) Business Days after Purchaser’s receipt of a Dispute Notice, then either party may request the American Arbitration Association (the “AAA”) to designate an arbitrator with relevant suitable expertise and the Arbitration shall begin on the Business Day immediately subsequent to the day on which the AAA designates an arbitrator and shall proceed continuously thereafter until concluded. The determination of the arbitrator shall be conclusive and binding upon both parties. The arbitrator conducting any arbitration shall be bound by the provisions of this Agreement and shall not have the power to add to, subtract from, or otherwise modify such provisions. The arbitrator shall consider only the specific issues submitted to it for resolution. Each party shall have the right to appear and be represented by counsel before said arbitrator and to submit such data and memoranda in support of their respective positions in the matter in dispute as may be reasonably necessary or appropriate in the circumstances. If the determination of the arbitration is not made on or prior to the then Scheduled Closing Date, then such Scheduled Closing Date shall automatically be extended until the date that is twelve (12) Business Days following such determination. The arbitrator shall be instructed to render his or her decision within five (5) Business Days of the commencement of the Arbitration, given the exigencies of the situation. Each party shall pay its own costs, fees and expenses in connection with any arbitration brought under this Section 6.6, and the expenses and fees of the arbitrator selected shall be borne by the losing party.

6.6.5 Notwithstanding anything to the contrary herein contained, from and after the Closing, with respect to any asserted Breach, expressly excluding the representations contained in Section 6.1.10 and 6.1.15 hereof and any representations and warranties set forth in any estoppel certificate delivered by Seller in lieu of any one of the Required Estoppel Certificates pursuant to Section 8.12.3 below, (a) Seller shall not have any liability to Purchaser

if Purchaser has received a credit against the Purchase Price or there is pending a Dispute in respect of which there have been deposited Escrow Funds pursuant to Section 6.6.2 and Section 6.6.3 above on account of such asserted Breach (except, in the case of such a Dispute, for the finally determined Claimed Damage as determined pursuant to Section 6.6.4) and (b) the aggregate liability of Seller arising by reason of or in connection with all such alleged Breaches asserted prior to the Closing shall not in any event exceed the Liability Cap.

6.7 “AS IS” Sale. Purchaser hereby acknowledges and agrees that at Closing, the Property shall be in its “AS IS” condition at the Closing Date, subject to all latent and patent defects (whether physical, financial or legal, including permitted title defects), based solely on Purchaser’s own inspection, analysis and evaluation of the Property and not in reliance on any records or other information obtained from Seller or on Seller’s behalf. Purchaser acknowledges that it is not relying on any statement or representation (other than representations, warranties, covenants and indemnifications contained in this Agreement) that has been made or that in the future may be made by Seller or any of Seller’s employees, agents, attorneys or representatives concerning the condition of the Property (whether relating to physical conditions, operation, performance, title, or legal matters).

6.8 Indemnification. Seller hereby agrees to indemnify and hold Purchaser harmless from and against any and all losses, costs, liabilities or expenses incurred or suffered by Purchaser, Holdco, Subsidiary REIT or Owner which arise or otherwise relate to the period prior to the Closing; provided, however, that such indemnity shall not include (i) any liabilities which, pursuant to the terms hereof, are intended to be shared by Seller and Purchaser in their capacity as members of Holdco from and after the Closing and (ii) any liabilities which result from a breach of any representations contained herein, which such breaches shall be governed by the provisions of Section 6.3 through 6.7 hereof including the limitations set forth in Section 6.5 hereof. The indemnification provided for hereunder shall not be subject to the conditions and limitations set forth in the Agreement; provided, further, for the avoidance of doubt, the terms of this Section 6.8(ii) shall not vitiate or otherwise diminish or reduce Purchaser’s right to assert a claim for a breach by Seller of one or more of Seller’s representations contained in this Agreement, including any certificate delivered pursuant to Section 8.12.3.

Except in the case of emergency and as set forth in the preceding sentence, Seller shall have no obligation to make, or cause Owner to make, any capital repairs to the Improvements through the Closing Date.

Notwithstanding anything to the contrary contained herein, Seller shall have the right to cause Owner to enter into New Leases with respect to any of the pending lease transactions which are described on Schedule 8.5 hereof provided that the terms of such New Lease comply with the requirements set forth in Schedule 8.5 hereto and are otherwise on commercially reasonable terms and conditions (any such New Lease being hereinafter referred to as a “Permitted New Lease”), and in such event (i) the amount of any brokerage commission in connection with such Permitted New Lease, (ii) the cost of any tenant improvements to be performed by the landlord under the terms of the Permitted New Lease, and (iii) the amount of any cash work allowances required to be given by the landlord to the tenant under the terms of the Permitted New Lease shall be paid in accordance with Section 4.2.7.

Seller shall promptly notify Purchaser of, and shall promptly deliver to Purchaser a copy of any notice Seller or Owner may receive, on or before the Closing, from any governmental authority, concerning a violation of laws at the Property that has not been previously disclosed to Purchaser.

Seller agrees to afford Purchaser and its employees and authorized agents with access to the Property from time to time prior to the Closing, at reasonable times and upon reasonable advance notice, provided that neither Purchaser nor any of its employees or agents shall enter any portion of the Property unless accompanied by a representative of Seller and that Seller shall not be required to incur any cost or expense or commence any action to afford Purchaser with such access.

If after the expiration of such one hundred eighty (180) day period, Seller has not cured such alleged default, Purchaser may elect to terminate this Agreement upon thirty (30) days prior written notice and receive a full refund of the Deposit and Interest accrued thereon and reimbursement from Seller up to an amount not to exceed [ ] ($[ ]), for the reasonable costs and expenses actually incurred by Purchaser in connection with Purchaser’s negotiation and execution of this Agreement and due diligence with respect to the Property; provided, however, that if such default has been cured within such thirty (30) day period, Purchaser’s election to terminate shall be null and void. Seller shall give Purchaser at least ten (10) days prior written notice of the new Scheduled Closing Date pursuant to this Section 8.10. Any default under the Condominium Declaration shall be deemed cured if Seller shall obtain a replacement Condominium Estoppel which shall not contain any exception relating to such default. Any matter which is the subject of an alleged default under the Condominium Declaration and subject to cure under this Section 8.10 shall not constitute a breach of any representation hereunder until such time as Seller is no longer entitled to cure the same.] [if applicable]

Seller shall give Purchaser at least ten (10) days prior written notice of the new Scheduled Closing Date pursuant to this Section 8.11. Any default under the Existing Mortgage Loan Documents shall be deemed cured if Seller shall obtain a replacement Existing Mortgage Loan Estoppel which shall not contain any exception relating to such default (or if Seller shall obtain any other written confirmation from the applicable lenders that such default has been cured). Any matter which is the subject of an alleged default under the Existing Mortgage Loan Documents and subject to cure under this Section 8.11 shall not constitute a breach of any representation hereunder until such time as Seller is no longer entitled to cure the same.] [if applicable]

8.12 Estoppels.

8.12.1

(a) [Seller shall use its commercially reasonable efforts to obtain an estoppel certificate from [The Board of Managers] of the Condominium prior to Closing with respect to the Condominium Declaration (the “Condominium Estoppel”) substantially in the form of Exhibit B attached hereto; and] [if applicable]

(b) [Within ten (10) Business Days after the date of this Agreement, Seller shall request an estoppel certificate from [Landlord] with respect to the [Landlord] Lease (the “[Landlord] Estoppel”) substantially in the form of Exhibit C attached hereto. Notwithstanding the foregoing, Purchaser acknowledges that receipt of an executed [Landlord] Estoppel from [Landlord] shall not constitute a precondition to Purchaser’s obligation to consummate the transactions contemplated herein.] [if applicable]

(c) [Within ten (10) Business Days after the date of this Agreement, Seller shall request an estoppel certificate from the lenders under the Existing Mortgage Loan with respect to the Existing Mortgage Loan Documents (the “Existing Mortgage Loan Estoppel”) substantially in the form of Exhibit D attached hereto.

Seller hereby agrees that it shall deliver the form of estoppel certificate attached hereto as Exhibit F (the “Standard Form of Estoppel Certificate”) to each of the Tenants for signature; provided, however, that Purchaser hereby acknowledges and agrees that it shall accept any Estoppel Certificate which (A) is dated within sixty (60) days of the Closing Date and (B) is substantially in the form of the estoppel certificate attached to each such Tenant’s Lease or, with respect to any Lease that does not include a form of estoppel certificate, an estoppel certificate which substantially incorporates the estoppel provisions expressly contained in any such Lease (the estoppel described in this clause (B) being hereinafter referred to as the “Tenant’s Form of Estoppel Certificate”); provided, further, that to be considered an Estoppel Certificate which satisfies the requirements of this Section 8.12.2, the certificate shall conform to, and not be materially and adversely inconsistent with, Tenant’s Form of Estoppel Certificate and in all cases, shall not allege any material default. Seller shall not be required to expend any money (other than nominal sums), provide any financial accommodations or commence any litigation in connection with obtaining any Estoppel Certificates and Purchaser agrees that delivery of Estoppel Certificates other than the Required Estoppel Certificates shall not be a condition to Closing hereunder. If for any reason Seller is unable to deliver any of the Required Estoppel Certificates [or the Condominium Estoppel] on the Closing Date, either Seller or Purchaser may, each in its sole discretion, adjourn the Scheduled Closing Date from time to time for a period not to exceed ninety (90) days, during which period Seller shall use commercially reasonable efforts to obtain such missing Required Estoppel Certificates [or the Condominium Estoppel].

8.12.3 Seller in its sole discretion shall have the right, but not the obligation, to provide to Purchaser Seller’s own estoppel in lieu of any one of the Required Estoppel Certificates (other than for any of the Tenants listed in clause (i) of Section 8.12.2 above) but in no event for more than 15% of the tenanted office space in the Premises if any one such Tenant delivers an estoppel alleging a default or other irregularity, or if Seller is unable to procure a sufficient number of Required Estoppel Certificates to satisfy the provisions of Section 8.12.2 above (but in no event for more than 15% of the tenanted office space in the Premises), and to thereby satisfy the condition to Closing in respect of such Required Estoppel Certificates. Any such estoppel shall provide that Seller shall indemnify Purchaser if any of the defaults or irregularities alleged by the applicable Tenants are correct. Any such estoppel and indemnity delivered by Seller shall be deemed to be rescinded and terminated to the extent the information contained therein is subsequently confirmed by an estoppel delivered by the applicable Tenant.

(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.

(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 (except that Purchaser shall receive a credit against the cash due at Closing for the amount of forty-five percent (45%) of any unpaid deductible on such casualty insurance policy) or any liability or obligation on the part of Seller by reason of said destruction or damage.

ARTICLE XII

DEFAULT

12.1 Default by Seller.

12.1.1 In the event that on or before the Closing Date Seller has defaulted on its obligations hereunder in any material respect, then, subject to the provisions set forth below, Purchaser shall be entitled, as its sole remedy, to either: (x) treat this Agreement as being in full force and effect and pursue only the remedy of specific performance against Seller (but no other action, for damages or otherwise, shall be permitted; provided, if specific performance is unavailable to Purchaser as a result of a willful breach by Seller of this Agreement, then Purchaser shall be permitted to institute an action for damages not to exceed Thirty Million Dollars ($30,000,000); or (y) terminate this Agreement and receive (i) the Deposit and Interest from the Escrow Agent in accordance with the terms and provisions of Section 3.2 hereof and (ii) reimbursement from Seller up to an amount not to exceed Dollars ($ ), for the reasonable costs and expenses actually incurred by Purchaser in connection with Purchaser’s negotiation and execution of this Agreement and due diligence with respect to the Property. Purchaser waives any right to pursue any other remedy at law or in equity for any default of Seller, including, without limitation, any right to seek, claim or obtain damages, other than in the case of Seller’s fraud or willful misconduct, but in no case shall Purchaser seek punitive damages or consequential damages. Notwithstanding anything to the contrary contained in this Agreement, if prior to the Closing Date Purchaser has or obtains knowledge that (a) Seller has defaulted on its obligations hereunder in any respect, and Purchaser nevertheless proceeds with the Closing, then the default by Seller as to which Purchaser shall have such knowledge shall be deemed waived by Purchaser and Seller shall have no liability to Purchaser or its successors and assigns in respect thereof, or (b) any of Seller’s representations or warranties set forth in Article VI are untrue in any respect, and Purchaser nevertheless proceeds with the Closing, then the breach by Seller of the representations and warranties as to which Purchaser shall have such knowledge shall be deemed waived by Purchaser, and such representations and warranties shall be deemed modified to conform them to the information that Purchaser shall have knowledge of and Seller shall have no liability to Purchaser or its successors or assigns in respect thereof. Purchaser shall promptly notify Seller in writing if Purchaser has or obtains knowledge that Seller has defaulted on its obligations hereunder in any respect.

12.1.2 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 or a breach by Purchaser of any representations or warranties made by Purchaser under this Agreement, and provided that such default or breach 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 Membership Interests 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 or breach 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 Membership Interests, all other claims to damages or other remedies being hereby expressly waived by Seller. Notwithstanding anything in this Agreement to the contrary (i) from and after the Closing, nothing contained herein shall limit Seller’s remedies at law or in equity as to the Surviving Termination Obligations and (ii) Purchaser shall have the right to cure any such default or breach by paying the Purchase Price at Closing, except in connection with a default or breach relating to Sections 7.1, 7.2, 7.6 or 7.7, 13.1, 14.1 and 16.8.

13.1.3 Seller shall indemnify, defend and hold harmless Purchaser and its affiliates, and its and their partners, members, trustees, advisors, officers and directors, against all losses, damages, costs, expenses (including reasonable fees and expenses of attorneys), causes of action, suits or judgments of any nature arising out of any claim, demand or liability to or asserted (i) by the Broker in connection with this transaction and (ii) by any broker, agent or finder, licensed or otherwise, claiming to have dealt with Seller in connection with this transaction other than the Broker.

Purchaser’s counsel may give any notices or other communications hereunder on behalf of Purchaser and Seller’s counsel may give any notices or other communications hereunder on behalf of Seller and each notice so given shall have the same force and effect as if sent by such party. For the avoidance of doubt, and notwithstanding anything to the contrary contained in this Agreement, in each instance where a party hereto has consent, approval, or notice must be delivered by a party to this Agreement, such consent, approval, or notice rights, the same shall only be deemed effective if in writing.

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 a court of law located in the City, County and State of New York, and if instituted in the federal court of the United States of America, in the federal court of the United States of America for the Southern District of 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 Norges Bank. This Agreement may not be assigned by either party except, in the case of Purchaser only, 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 any direct or indirect beneficial ownership interests in Purchaser shall constitute an assignment of this Agreement. 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.

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, together with the Other Purchase Agreements, contain the final and entire agreement between the parties hereto with respect to the sale and purchase of the Membership Interest 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, in the Exhibits and Schedules attached hereto or in the Other Purchase Agreements. 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. The parties shall work together in good faith to replace any such invalid or unenforceable provision with terms and provisions which are valid and enforceable and reflect the intention of the parties.

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.

16.15 Prevailing Party. Should either party employ an attorney to enforce any of the provisions hereof (whether before or after Closing, and including any claims or actions involving amounts held in escrow, if any), the non-prevailing party in any final judgment agrees to pay the other party’s reasonable attorneys’ fees and expenses in or out of litigation and, if in litigation, trial, appellate, bankruptcy or other proceedings, expended or incurred in connection therewith, as determined by a court of competent jurisdiction. The provisions of this Section 16.15 shall survive Closing and/or any termination of this Agreement.

16.16 Real Estate Reporting Person. Escrow Agent is hereby designated the “real estate reporting person” for purposes of Section 6045 of the Code and Treasury Regulation 1.6045-4 and any instructions or settlement statement prepared by Escrow Agent shall so provide. Upon the consummation of the transaction contemplated by this Agreement, Escrow Agent shall file Form 1099 information return and send the statement to Seller as required under the aforementioned statute and regulation. Seller and Purchaser shall promptly furnish their federal tax identification numbers to Escrow Agent and shall otherwise reasonably cooperate with Escrow Agent in connection with Escrow Agent’s duties as real estate reporting person.

16.17 No Recording. Neither this Agreement nor any memorandum or short form hereof shall be recorded or filed in any public land or other public records of any jurisdiction, by either party and any attempt to do so may be treated by the other party as a breach of this Agreement.

16.18 No Other Parties. This Agreement is not intended, nor shall it be construed, to confer upon any person or entity, except the parties hereto, the parties to the Other Purchase Agreements, and their respective heirs, successors and permitted assigns, any rights or remedies under or by reason of this Agreement.

16.19 Waiver of Trial by Jury. 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. Seller shall have the right to structure the transactions contemplated hereby 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 and/or Owner 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 or Owner 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 and Owner from and against any and all liabilities, costs, damages, claims or demands arising from the cooperation of Purchaser and Owner 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 Scheduled Closing Date for up to thirty (30) days in the aggregate in order to effect such exchange.
