3.                                       PURCHASE PRICE.  The purchase price is $114,050,000 (the “Purchase Price”), which Buyer agrees to pay (i) 10,000,000 in immediately available funds as Earnest Money (together with any interest earned thereon, “Earnest Money”) to be delivered to Stewart Title Insurance Company (the “Escrow Agent”) upon execution hereof and held in accordance with the provisions of paragraph 18 hereof; and (ii) $104,050,000 in immediately available funds at Closing, adjusted at Closing for prorations, closing costs and other agreed expenses, each as provided for herein.  All payments by Buyer hereunder shall be in the form of a wire transfer of immediately available federal funds to an account designated by Seller, or Escrow Agent, as applicable.

4.                                       CLOSING DATE.  Subject to all the provisions of this Contract, the closing of this Contract (“Closing”) shall take place at the offices of counsel to Buyer or Buyer’s lender on May 27, 2011 (“Closing Date”), or prior thereto by mutual consent, and possession shall be delivered to Buyer at Closing; subject, however, to (a) either party’s right to extend the scheduled Closing Date one or more times not to exceed an aggregate extension of more than three (3) Business Days for each party, by giving notice thereof to the other party on or prior to the scheduled Closing Date and (b) extensions of the scheduled Closing Date as expressly permitted elsewhere in this Contract, as same may be adjusted as provided in the foregoing clauses (a) and (b), being TIME OF THE ESSENCE.  For the avoidance of doubt, the Closing Date will be deemed to commence at 12:01 a.m. on the Closing Date.

5.                                       PRORATIONS AND DELINQUENT RENTS.  Seller shall pay all real estate taxes, sewer taxes, water charges and rents levied and assessed against the Property and all installments of special assessments due prior to the Closing Date.  All such taxes and installments of special assessments becoming due and accruing during the calendar year of Closing shall be prorated between Seller and Buyer.  Utilities (except to the extent directly paid by Tenant), payments under the Service Contracts, any rents under the Lease and other customary prorations, if applicable, shall be prorated as of the Closing Date.  To the extent possible, utilities (including a final water meter reading) will be read on the date prior to Closing (with Seller paying bills to such date) and transferred to Buyer’s name as of the Closing Date.  To the extent final numbers are not available as of Closing, then the apportionments thereof made at the Closing shall be upon the basis of the tax, water, or other utility rates for the immediately preceding year applied to the latest assessed valuation, but after the real property taxes, water rates and charges, sewer taxes and rents or utility charges (as the case may be) are finally fixed for the current fiscal year, Seller and Buyer shall make a recalculation of the apportionment thereof within thirty (30) days after such numbers are known, and Seller or Buyer, as the case may be, shall make an appropriate payment to the other party based on such recalculation within thirty (30) days after the parties agree on the recalculation.  Seller’s obligation to make payment under this paragraph 5 shall be secured by the Extell Guaranty, defined below.

If on the Closing Date Tenant is in arrears in the payment of rent, rents received from such tenant(s) after the Closing Date shall be applied in the following order of priority: (i) first,

2

to the month in which received, (ii) then to the month or months following the month in which the Closing occurred, (iii) then to the month in which Closing occurred, and (iv) then to the period prior to the month in which the Closing occurred.  The Seller agrees to not pursue Tenant post-Closing for any claims that Seller may have against Tenant under the Lease or otherwise.

The provisions of this paragraph 5 shall survive Closing.  For the avoidance of doubt, the liability limitations contained in paragraph 8 below shall not apply to this paragraph 5.

6.                                       PERMITTED EXCEPTIONS; TITLE INSURANCE; VIOLATIONS.

(a)                Seller shall convey, and Buyer shall accept title to the Property, subject only to the Permitted Exceptions (as defined below).  Buyer has received and reviewed the Certificate and Report of Title (File No.  EAM61036NY) from EAM Land Services, Inc. as Agent for Stewart Title Insurance Company (“Title Company”) with an Effective Date of March 14, 2011 (“Title Evidence”) and survey by Erlandsen Crowell & Shaw dated April 22, 2011 (“Survey”), (ii) it approves the Permitted Exceptions, and (iii) the Property shall be conveyed to Buyer subject only to the Permitted Exceptions.  Buyer shall have a right to order an update to the Title Evidence and Survey through the Closing Date.  If any update to (A) the Title Evidence reflects any title exceptions that are not Permitted Exceptions or (B) the Survey shows any easement, right of way, encroachment, conflict, protrusion or other matters that are not Permitted Exceptions and are not shown on the Survey ((A) and (B) are collectively referred to herein as the “Non-Permitted Exceptions”), Buyer shall give written notice thereof (“Buyer’s Title Notice”) to Seller within five (5) Business Days of Buyer’s receipt of such update.

(b)               Seller shall (i) eliminate any and all of the Non-Permitted Exceptions that may be removed by the payment of a liquidated sum of money not in excess of $1,000,000, in the aggregate (the “Removal Amount”) (except in the case of (ii) hereinbelow, in which case there shall be no monetary limit upon the amount to be paid by Seller for the removal of such Non-Permitted Exceptions), and (ii) remove (a) those voluntarily caused to be filed of record by Seller and (b) judgments, liens, mortgages, security interests or similar security instruments filed against the Property and any payments required thereby ((i) and (ii) collectively, the “Required Removal Exceptions”).

(c)                In the event that there exist Non-Permitted Exceptions that are not Required Removal Exceptions (“Optional Removal Exceptions”), Seller shall notify Buyer by no later than the sooner to occur of (a) the Closing Date and (b) five (5) Business Days after Seller’s receipt of Buyer’s Title Notice, of Seller’s election to either cure and remove or not to cure or remove such Optional Removal Exceptions; provided that Seller’s failure to so notify Buyer shall be deemed to be Seller’s election not to cure or remove.  If Seller notifies Buyer of Seller’s intention (or is deemed to have elected) not to cure or remove the Optional Removal Exceptions, then Buyer may elect to either (A) not consummate the transactions contemplated hereby and receive a refund of the Earnest Money, in which event this Contract shall be terminated and of no further force and effect, and thereafter neither of the parties hereto shall have any rights or obligations to the other hereunder or (B) consummate the transactions contemplated hereby subject

3

to such additional Optional Removal Exceptions and proceed to Closing with an abatement of the Purchase Price in an amount equal to the reasonable cost to cure or remove such Optional Removal Exceptions, not to exceed the Removal Amount; provided that Buyer’s failure to send written notice of the election available to it pursuant to this sentence within ten (10) Business Days after request by Seller for such election, shall be deemed an election by Buyer to close under clause (B).  If Seller notifies Buyer of Seller’s intention to cure or remove any or all of the Optional Removal Exceptions, Seller shall be entitled to adjourn the Closing Date to the extent permitted under paragraph 6(d) below in order to effect such cure or removal, and shall have until two (2) Business Days prior to the Closing Date, as the same may have been adjourned under paragraph 6(d) below, to cure or remove such Optional Removal Exceptions; provided that if Seller fails to so cure or remove such Optional Removal Exceptions by the Closing Date, as the same may have been adjourned under paragraph 6(d) below, then Buyer may elect to either (A) not consummate the transactions contemplated hereby and receive a refund of the Earnest Money, in which event this Contract shall be terminated and of no further force and effect, and thereafter neither of the parties hereto shall have any rights or obligations to the other hereunder or (B) consummate the transactions contemplated hereby subject to such additional Optional Removal Exceptions and proceed to Closing with an abatement of the Purchase Price in an amount equal to the reasonable cost to cure or remove such Optional Removal Exceptions, but not to exceed the Removal Amount.

(d)               Seller shall have the right to adjourn the Closing Date, from time to time, up to thirty (30) days in the aggregate for the purpose of curing or removing any Non-Permitted Exceptions provided that Seller shall at all times during such adjournment period diligently pursue such cure or removal.

(e)                For the purposes of this paragraph 6, “Permitted Exceptions” means:

(i)                                     all matters set forth on Schedule 6(e) attached hereto;

(ii)                                  liens for unpaid taxes, assessments, charges, rents and any other governmental charges with respect to the Property, which are not yet due and payable and are apportioned in accordance with the provisions of paragraph 5 hereof;

(iii)                               the Lease and the rights of the Tenant thereunder; and

(iv)                              Survey made by Malcolm M. Shaw dated 04/22/2011 last revised 512/2011 shows a 7 to 16 story brick building.  Further shows:

(f)                  Buyer acknowledges that as of the date of execution of this Contract, Seller has delivered satisfactory evidence to Buyer that it has cured those violations noticed of record as of the date hereof with respect to the Property by the Fire Department of the City of New York.

(g)               In the event any notes or notices of any violations of law or municipal ordinances, orders or requirements (“Violations”) affecting the Property are noticed of record or issued to Seller by any federal, state, county or municipal department, agency, authority or bureau having or asserting jurisdiction prior to Closing, Seller shall either cure the same prior to Closing or deposit with Title Company in a manner satisfactory to Buyer and Title Company sufficient funds to (i) cause the cure and dismissal of such Violations after Closing, (ii) remove from the public land records any lien attaching to the Property as a result of the foregoing Violations described in clause (i), and to (iii) pay any fees or fines with respect to such Violations described in clauses (i) and (ii); provided that the Title Company will issue insurance to Buyer without reference to such matters, and Seller shall, after the Closing diligently proceed to cure such matters.  Notwithstanding the foregoing, Buyer acknowledges that certain departments of the City of New York, including but not necessarily limited to the Fire Department, do not remove notices of violations from the record once they are cured or satisfied, and in such instances “dismissal” or “cure” shall not include removal from such records. The provisions of this subparagraph (g) shall survive Closing.

Notwithstanding anything to the contrary in this paragraph 6, Seller shall have no obligation to clear or cure any Non-Permitted Exception that is the result of actions of, failure to act by, or the obligations of Tenant (a “Tenant-Caused Non-Permitted Exception”).  Seller agrees to take all commercially reasonable actions that it is permitted to do (or not prevented from undertaking) under the Lease to cause Tenant to clear any such Tenant-Caused Non-Permitted Exception.  In the event Seller is unable to cause Tenant to clear any Tenant-Caused Non-Permitted Exception prior to Closing, Buyer may, as its sole remedy, terminate this Contract by written notice to Seller and Escrow Agent, in which instance Escrow Agent shall return the Earnest Money to Buyer and this Contract shall terminate and have no further force and effect, except those provisions that specifically survive termination.

such representations hereunder, and (iii) Seller does not credit Buyer an amount equal to the damages in the event the Floor is exceeded.

(iii)                               In the event Buyer discovers a breach of a Seller’s representation at or prior to Closing in excess of the Floor, (as opposed to a change in circumstances occurring after the date hereof, which shall not be deemed to be a breach by Seller), Buyer’s sole right and remedy arising by reason of any such untrue or incomplete representation shall be to terminate this Contract, and in such event Seller reimburse Buyer for Buyer’s reasonable third-party due diligence costs and expenses incurred in connection with negotiation of this Contract, provided the same are substantiated by invoices or other evidence and up to a maximum reimbursement amount of $75,000.

(iv)                              The acceptance by Buyer of the Deed shall constitute conclusive proof that Seller has performed all of its obligations under this Contract and shall have no further or continuing obligations or liabilities to Buyer arising under or by virtue of this Contract or out of the transactions contemplated by the parties hereto, except as may be expressly set forth in this Contract.  Notwithstanding the foregoing, Seller’s representations shall survive Closing subject to the Floor for a period of nine (9) months, except that Buyer shall have no right or claim in respect of any such representation unless and until the aggregate amount of claims in respect of all such representations, as reasonably estimated, shall exceed the Floor, and then only to the extent such claims do not exceed $2,500,000, and Buyer shall be required to commence any action based on such claims within twelve (12) months after the Closing.

13.                                 REAL ESTATE BROKER.  Seller confirms and represents to Buyer that it engaged no exclusive agent or broker in connection with this transaction with the exception of Stan Johnson Company and Williamson, Picket, Gross Inc., both of whom shall be paid by Seller pursuant to separate agreements with Seller.  Each party confirms and represents to the other

party that it knows of no other broker entitled to or who may claim a right to a commission in connection with this transaction.  In the event any other agent or broker makes a claim for a broker’s, finder’s or other fee related to this transaction, the party having previously interacted with the agent or broker making such claim shall indemnify, defend and hold harmless the other party from any loss, liability, damage, cost or expense, including, without limitation, reasonable attorney’s fees, court costs and other legal expenses paid or incurred by Seller, in any way related to such a claim.  The provisions of this paragraph shall survive Closing or termination of this Contract indefinitely.

15.                                 RISK OF LOSS; INSURANCE; CASUALTY; CONDEMNATION.

(a)                Subject to the further terms of this paragraph 15, until Closing, the risk of loss or damage to all or part of the Property by fire or other casualty or by taking by eminent domain shall be assumed by Seller.

(b)               Notwithstanding anything contained herein to the contrary, if prior to Closing there shall occur (i) damage to the Property by fire or other casualty, or (ii) a taking by condemnation that would (x) cause the automatic termination of the Lease, or (y) as a result thereof, the Lease is terminated (or terminable by the Tenant and Tenant has not waived or forfeited such termination right), then Seller shall notify Buyer of such termination (or right of termination) of the Lease within five (5) days after such damage or taking, and Buyer shall have the right to terminate this Contract by written notice to Seller within ten (10) days of Buyer’s receipt of written notice of such termination (or right of termination), in which instance this Contract shall thereafter be of no further force and effect.

(c)                Seller agrees to give Buyer written notice of any fire or other casualty occurring at the Property between the date hereof and the date of the Closing of which

15

Seller obtains Knowledge, which notice shall be given to Buyer within five (5) days of such occurrence and shall be accompanied by an estimate from an Approved Engineer (as hereinafter defined) of the cost to restore the Property to the condition prior to such casualty and the estimated completion date.  Seller further agrees to give Buyer written notice of any actual or threatened condemnation of all or any part of the Property of which Seller obtains Knowledge within five (5) days of Seller obtaining such Knowledge.

(d)

(i)                                     if prior to the Closing there shall occur damage to the Property caused by fire or other casualty (which damage does not meet the criteria set forth in paragraph 15(b)) with respect to which the cost to repair to the condition existing prior to such casualty as reasonably determined by an engineer selected by Seller which is reasonably satisfactory to Buyer (“Approved Engineer”) would be $1,000,000 or more (the “Projected Repair Cost”), then the Closing shall be adjourned as necessary to allow the permitted time for Seller to make an election as set forth herein, and Seller may elect, by written notice given to Buyer within twenty (20) days after such casualty, to (1) terminate this Contract, in which event the Earnest Money shall be returned to Buyer, this Contract shall thereupon be null and void and neither party hereto shall have any further obligation to the other, or (2) adjourn Closing hereunder for a period to be established by Seller, not to exceed six (6) months, to allow Seller to repair the Property to the condition existing prior to such casualty, at which point the Closing shall occur as set forth herein.

(ii)                                  If prior to the Closing there shall occur a taking by condemnation of any “material portion of the Property” (as hereinafter defined) (which taking by condemnation does not meet the criteria set forth in paragraph 15(b)), the Closing shall be adjourned as necessary to allow the permitted time for Buyer to make an election as set forth herein, and Buyer may elect to terminate this Contract by written notice given to Seller within fifteen (15) days after Seller has given Buyer the notice of such condemnation, in which event the Earnest Money shall be returned to Buyer and this Contract shall thereupon be null and void and neither party hereto shall have any further obligation to the other.  If Buyer does not elect to terminate this Contract, then the Closing shall take place as herein provided with an abatement of the Purchase Price equal to the Projected Repair Cost.  The proceeds of rent interruption insurance, if any, shall be apportioned at Closing.

(e)                If prior to the Closing there shall occur (a) damage to the Property caused by fire or other casualty with respect to which the cost to repair to the condition existing prior to such casualty, as reasonably determined by an Approved Engineer is less than $1,000,000 or (b) a taking by condemnation of any part of the Property that does not include a “material portion of the Property,” neither party shall have the right to terminate its obligations under this Contract by reason thereof, but there will be an abatement of the Purchase Price equal to the Projected Repair Cost.  The proceeds of rent interruption insurance, if any, shall be apportioned at Closing.

16

(f)                  For the purposes of this paragraph 15, the term “material portion of the Property” shall mean (i) more than 1% of the aggregate floor area of the Property, (ii) the denial of access to any street adjacent to the Property for more than five (5) days (consecutive or non-consecutive) within a sixty (60) days consecutive time period or (iii) a portion of the Property sufficient to permit Tenant to terminate the Lease or otherwise give rise to Tenant’s right to exclude such portion from Tenant’s premises under the Lease.

(g)               Nothing contained in this paragraph 15 shall be construed to impose upon Seller any obligation to repair any damage or destruction caused by fire or other casualty or condemnation, but, except as otherwise provided herein, Seller shall have the right to do so and to utilize any insurance proceeds or condemnation awards for such purposes.

(h)               Seller and Buyer expressly acknowledge and agree that the provisions of this paragraph 15, and not Section 5-1311 of the New York State General Obligations Law, shall govern the rights and obligations of the parties in the event of a fire or other casualty.  Seller agrees to maintain its existing insurance coverages to the Closing Date.

16.                                 ASSIGNMENT.  Subject to paragraph 21 hereof, Buyer may not assign its rights under this Contract or in any way modify its ownership structure without the prior written consent of Seller; provided, however, that Buyer may assign its interests hereunder to a wholly owned direct or indirect subsidiary of Buyer or Buyer’s parent entity upon written notice to Seller.  Notwithstanding the foregoing, Seller hereby agrees that without such notice, Buyer may, contemporaneously with Closing, assign its rights under this Contract to GPT Properties Trust, a Maryland real estate investment trust and a wholly owned subsidiary of Buyer.

17.                                 DEFAULT AND REMEDIES.  Seller or Buyer shall be in default under this Contract if either fails to comply with any material covenant, agreement or obligation within any time limits required by this Contract.  Following a default by either Seller or Buyer under this Contract, the other party shall have the following remedies:

(a)                If Seller defaults, Buyer may (i) specifically enforce this Contract; or (ii) terminate this Contract by written notice to Seller.  If Buyer elects to terminate this Contract, the Earnest Money shall be returned to Buyer upon written demand and neither party shall have any further rights or obligations hereunder, except those that expressly survive termination.

(b)               If Buyer defaults, Seller shall be entitled to terminate this Contract by written notice to Buyer and retain the Earnest Money as liquidated damages as Seller’s sole and exclusive recourse and remedy, the parties recognizing that it would be extremely difficult to ascertain the extent of actual damages caused by Buyer’s breach, and that the Earnest Money represents as fair an approximation of such actual damages as the parties can now determine, and following such termination, neither party shall have any further rights or obligations hereunder, except those that expressly survive termination. Notwithstanding the foregoing, Seller agrees that a failure of wire transferred funds to reach Seller’s designated account on the Closing Date shall not constitute a default by Buyer hereunder provided Buyer provides reasonable evidence that the wire transfer was

17

initiated on or prior to the Closing Date and the funds are received no later than two (2) Business Days thereafter.

Notwithstanding any limitation of remedies above, if, as a result of a default under this Contract, either Seller or Buyer employs an attorney to enforce its rights in a legal proceeding, the non-prevailing party in such legal proceeding, if determinable, shall reimburse the prevailing party for all reasonable attorneys’ fees, court costs and other legal expenses incurred by the prevailing party in connection with such proceeding.

18.                                 DISPOSITION OF EARNEST MONEY; ESCROW AGENT.

(a)                The funds represented by the Earnest Money shall be held in escrow by the Escrow Agent in an interest bearing bank account at Citibank, N.A. (“Depositary Bank”).  The Earnest Money, together with any interest earned thereon (a) shall become the property of the Seller (i) upon the delivery of the Deed, or (ii) after proper demand by the Seller without written objection from the Buyer in the manner described below; (b) shall be returned to the Buyer after proper demand by the Buyer without written objection from the Seller in the manner described below; or (c) shall be delivered to either the Seller or the Buyer in accordance with a final judgment, which is no longer subject to, or the subject of, an appeal, of a court of competent jurisdiction directing the disposition of the Earnest Money.

(b)               It is understood and agreed that the Escrow Agent’s sole duties hereunder are as provided herein and that the Escrow Agent in the performance of its duties hereunder is hereby released and exculpated from all liability except for willful malfeasance or gross negligence and shall not be liable or responsible for anything done or omitted to be done in good faith as herein provided.  If either the Seller or the Buyer makes a written demand upon the Escrow Agent setting forth the basis for such demand, for payment of all or a portion of the Earnest Money, the Escrow Agent shall give at least five (5) Business Days’ written notice to the other party of such demand and of its intention to pay over the amount demanded on a stated date.  If before the proposed payment date the Escrow Agent does not receive a written objection to the proposed payment setting forth the basis for such objection, the Escrow Agent is hereby authorized and directed to make such payment.  If before the proposed payment date such other party (or its counsel) delivers to the Escrow Agent a written objection to such payment setting forth the basis for such objection, the Escrow Agent shall promptly deliver a copy of such objection to the party originally demanding payment, and shall continue to hold such amount until otherwise directed by the joint written instruction of the Seller and the Buyer or by a final judgment of a court which is no longer subject to, or the subject of, an appeal.  In the event that a dispute shall arise as to the disposition of all or any portion of the Earnest Money held by the Escrow Agent, the Escrow Agent shall, at its option, either (a) commence an action of interpleader and deposit the same with a court of competent jurisdiction, pending the decision of such court, and shall be entitled to rely upon the final judgment of any such court with respect to the disposition of all or any portion of the Earnest Money provided that such judgment is no longer subject to, or the subject of, an appeal or (b) hold the same pending receipt of joint instructions from the Seller and the Buyer and shall be entitled to rely upon such joint instructions with respect to the

18

disposition of all or any portion of the Earnest Money.  The Escrow Agent shall be entitled to consult with counsel and be reimbursed for all reasonable expenses of such consultation with respect to its duties as Escrow Agent and shall be further entitled to be reimbursed for all reasonable out of pocket expenses incurred in connection with such activities.  All such expenses shall be paid by the party whose position shall not be sustained.

(c)                The Escrow Agent shall have the right to rely upon the certificates, notices and instruments delivered to it pursuant hereto, and all the signatures thereto or to any other writing received by the Escrow Agent purporting to be signed by any party hereto, and upon the truth of the contents thereof.  The Escrow Agent shall not be bound by any modification of this Agreement which affects the rights or duties of the Escrow Agent unless it shall have given its prior written consent thereto.  The Escrow Agent may, but shall not be required to, institute or defend any action or legal process involving any matter referred to herein which in any manner affects the Escrow Agent or its duties or liabilities hereunder, unless or until requested to do so by the Seller or the Buyer and then only upon receiving full indemnity in an amount, and of such character, as the Escrow Agent shall require, against any and all claims, costs, liabilities, judgments, attorneys’ fees and other expenses of any kind in relation thereto.

(d)               The Seller and the Buyer agree, severally, to indemnify and save the Escrow Agent harmless from any losses, claims, liabilities, judgments, attorneys’ fees and other expenses of every kind and nature which may be incurred by the Escrow Agent by reason of its acceptance of, and its performance under, this Contract, other than as a result of the Escrow Agent’s willful or grossly negligent behavior.

(e)                The Escrow Agent may at any time resign hereunder by giving notice of its resignation to the Seller and the Buyer at least fifteen (15) days prior to the date specified for such resignation to take effect and, upon the effective date of such resignation, the Earnest Money shall be delivered by the Escrow Agent to such person or entity as the Seller and the Buyer may have jointly designated in writing or to such person or entity as may be designated as hereinafter provided as the successor Escrow Agent, whereupon all duties and obligations of the Escrow Agent named herein shall cease and terminate.  If no such person or entity shall have been designated by both the Seller and the Buyer by the date which is five (5) days prior to the date specified for such resignation to take effect then the Escrow Agent may designate a law firm or bank in New York City to act as escrow agent hereunder.

(f)                  Each of Seller and Buyer represents that its Federal Taxpayer I.D. Number is as set forth on the signature page.  The party receiving any portion of the interest earned on the Earnest Money shall pay all taxes on and with respect to the same.  The Escrow Agent shall not be responsible for any diminution in value of the Earnest Money, loss of any principal or interest thereon, or penalties incurred with respect thereto, for any reason whatsoever, provided the Earnest Money has been invested by the Escrow Agent as provided herein.

19

(g)               Buyer and Seller by executing this agreement consent to the Escrow Agent’s use of Citibank, N.A. as Depositary Bank and agree to hold the Escrow Agent harmless for all loss, cost or damage incurred by reason of any failure of the Depositary Bank.

19.                                 ENTIRE AGREEMENT AND MANNER OF MODIFICATION.  This Contract, and any attachments or addenda hereto, constitute the complete agreement of the parties concerning the Property, supersede all other agreements and may be modified only by initialing changes herein or by written agreement.

20.                                 NOTICES.  All notices, consents, approvals, requests or other communications (collectively “notices”) which may or are required to be sent, delivered, given, made, maintained or obtained under this Contract shall be in writing and shall be served by facsimile (confirmed as set forth below) or by reputable national or international overnight delivery service guaranteeing next day delivery and providing a receipt.  All notices shall be addressed to the parties at the respective addresses as set forth below, including counsel, except that any party may, by notice in the manner provided above, change this address for all subsequent notices.  Notices to the Escrow Agent shall be sent as provided below.  Notices shall be deemed served and received upon the earlier of the date of delivery by a nationally or internationally recognized overnight delivery service or on the date of delivery by facsimile if such delivery occurs prior to 5 p.m. local time for the addressee or on the following day if received thereafter, provided that any facsimile notice must be confirmed by overnight delivery deposited within two Business Days after delivery by facsimile.  A party’s failure or refusal to accept service of a notice shall constitute delivery of the notice.

21.                                 EXCHANGE.  Both parties shall be entitled to exchange other property of like kind and qualifying use within the meaning of Section 1031 of the Code and the Regulations promulgated thereunder, for fee title in the property which is the subject of this Contract; provided, however, that the party electing to implement such an exchange shall indemnify and hold harmless the other party from and against any loss or liability (including, without limitation, reasonable attorneys’ fees and disbursements) such party may incur as a result of said exchange.  Seller and Buyer expressly reserve the right to assign such party’s respective rights, but not its obligations, hereunder to a qualified intermediary on or before the Closing Date and both parties agree to cooperate with each other so long as the other party incurs no additional costs therefor.  Each party specifically acknowledges that this Contract is not conditioned upon such party’s ability to effect a 1031 Exchange.  The indemnification and hold harmless provisions of this paragraph shall survive Closing or termination of this Contract indefinitely.

22.                                 NO SURVIVAL.  Except as otherwise expressly provided to the contrary in this Contract, the delivery and acceptance of the Deed at the Closing shall be deemed to constitute full compliance by Seller with all of the terms, conditions and covenants of this Contract on Seller’s part to be performed, and the representations, warranties, covenants or other obligations of Seller set forth in this Contract shall not survive the Closing, and no action based thereon shall be commenced after Closing.

23.                                 PROPERTY TAX APPEALS.  Seller has filed a property tax appeal for the tax fiscal year 2010/2011, and has retained counsel (“Tax Counsel”) to prosecute the appeal.  Buyer shall assume the prosecution of such proceedings and the contract with Tax Counsel and shall

20

pay all legal, accounting and other expenses which may be incurred in connection with such appeal.  If such determination shall result in a refund or credit with respect to the tax year in which the Closing occurs, then the net amount of such refund or credit (after paying therefrom pro rata all Buyer’s costs including attorney’s fees in connection with such proceedings and any refunds or credits owed to Tenant under the Lease and paying all amounts due to Tenant) shall be apportioned between Seller and Buyer based upon the Closing Date, and any amount due to Seller shall be promptly paid by Buyer.  The provisions of this paragraph shall survive Closing.

24.                                 FINANCIALS.  Following Closing, Seller shall provide Buyer with reasonable access to the books and records of the Property for the purpose of preparing audited financial statements for the Property with respect to 2008, 2009 and 2010 and the stub 2011 period, such financial statements to be prepared at the Buyer’s sole cost and expense.  Seller shall provide Buyer or its accountants with such certifications and representations (to the best of Seller’s actual knowledge) as to such books and records with respect to the Property as Buyer or its accountants shall reasonably require in order to enable Buyer its accountants to prepare such audited financial statements in accordance with the requirements of Regulation S-X, Rule 3-14 of the U.S. Securities and Exchange Commission.  Buyer shall be responsible for all out-of-pocket costs or expenses incurred by Seller in connection with the preparation of such certifications and representations.  This obligation shall survive the Closing until the second annual anniversary of the Closing Date.

25.                                 CERTIFICATE OF OCCUPANCY.     Buyer and Seller acknowledge that a permanent certificate of occupancy has not been issued for the Building.  Seller agrees that it will cause a permanent certificate of occupancy for the entire Building issued by the Department of Buildings of the City of New York (the “PCO”) to be issued on or before November 27, 2012 (or, if the Closing occurs later than May 27, 2011, such later date that is eighteen (18) months after the Closing Date) (the “PCO Resolution Date”).  At Closing, the sum of $750,000 (the “Escrowed Funds”) shall be held back from the closing proceeds in escrow with the Escrow Agent, pursuant to the terms of an escrow agreement to be entered into by the parties at Closing (the “PCO Escrow Agreement”), which PCO Escrow Agreement shall provide as follows:

(a)                upon delivery by Seller to Buyer prior to the PCO Resolution Date (and in accordance with the notice provisions of this Contract) of the certificate of occupancy that Seller tenders as the PCO, Buyer will have five (5) Business Days to object to automatic disbursement by Escrow Agent of the Escrowed Funds to Seller, upon only one of the two following grounds: (i) that the certificate of occupancy is not in fact a PCO, or (ii) that the PCO does not apply to the entire Building. If Buyer timely objects to disbursement of the Escrowed Funds as provided above, Escrow Agent shall continue to hold the Escrowed Funds in escrow until the PCO is delivered to Buyer as required herein. If Buyer does not timely object to disbursement of the Escrowed Funds as provided above, the Escrowed Funds shall be automatically disbursed to Seller on the sixth (6th) Business Day after delivery of the PCO to Buyer as required herein;

(b)               in the event the PCO is not received by Buyer on or before the PCO Resolution Date, the Escrowed Funds shall automatically be disbursed by Escrow Agent to Buyer;

21

(c)                in the event of either (a) or (b) above, Seller shall be relieved of all further obligations set forth in this paragraph 25; and

(d)               the costs and fees charged by Escrow Agent in connection with such escrow shall be paid by Seller.

Prior to the PCO Resolution Date, Seller and its representatives shall, upon reasonable prior notice to Buyer, be granted access to the Property to perform work necessary to obtain the PCO, provided that Seller shall (i) exercise reasonable care at all times that Seller shall be present upon the Property, (ii) at Seller’s expense, observe and comply with all Applicable Laws and any reasonable conditions imposed by any insurance policy then in effect with respect to the Property and made known to Seller, (iii) not engage in any activities which would violate the provisions of any permit or license pertaining to the Property, (iv) not unreasonably disturb Tenant or interfere with its use of the Property pursuant to the Lease; (v) not interfere with the operation and maintenance of the Property; provided, however, that Buyer agrees that it will enforce the provisions of the Lease to require Tenant to allow Seller and its representatives to have access to the Property to perform the work required to obtain the PCO (but notwithstanding the foregoing, Buyer will not be required to bring any legal proceedings to enforce Tenant’s lease, including, without limitation, any action to terminate Tenant’s lease), (vi) repair any damage to the Property resulting from Seller’s activities at the Property, (vii) indemnify, defend and hold Buyer harmless from and against all claims, costs, liabilities demands and expenses, including, without limitation, reasonable attorney’s fees, court costs and other legal expenses, resulting from such work (including property damage or personal injuries suffered by any party on the Property at the request of Seller, Buyer or Tenant in connection with such work), other than to the extent that such claims, costs, liabilities demands and/or expenses arise in whole or in part from the gross negligence or willful misconduct of Buyer or its representatives, employees or agents. Upon Buyer’s request, Seller shall provide evidence of insurance coverage in an amount reasonably satisfactory to Buyer to cover Seller’s obligations under this paragraph. Buyer and Seller agree that the costs and fees charged by Escrow Agent in connection with such escrow shall be paid by Seller.

When Seller delivers the PCO to Buyer, delivery shall be made as provided at the end of this Contract, with a copy also to the below:
