Section 2.3	Buyer’s Review and Seller’s Disclaimer.
(a)	During the Diligence Period, Buyer shall be permitted to perform, at its own expense, such environmental tests and assessments as are customary and standard with respect to the purchase and sale of commercial real estate in the New York metropolitan area (the “Environmental Assessment”) by a reputable company licensed to perform such assessments in the state of New York (“Consultant”).
(b)	Seller shall permit Consultant reasonable access to the Property during the Diligence Period to perform the Environmental Assessment, and shall cooperate with

-112-

Consultant in the performance of the Environmental Assessment but shall not be obligated to incur any expense in connection therewith. In connection with any entry by Consultant onto the Property, Buyer shall give Seller reasonable advance written notice of such entry and shall conduct such entry and any related inspections so as to minimize, to the greatest extent possible, interference with Seller’s business and otherwise in a manner reasonably acceptable to Seller. To the extent Consultant, or its agents, employees or contractors cause any damage to, performs any tests on, or otherwise alters the Property during any such entry, Buyer shall promptly restore the Property to the condition it was in prior to such entry. Without limiting the foregoing, prior to any entry to perform any on-site testing, Buyer shall give Seller reasonable written notice thereof, including, without limitation, the identity of the persons or entities who will perform such testing and the location and proposed scope of the testing. Seller shall approve or disapprove the proposed testing, which approval shall not be unreasonably withheld, within five (5) business days after receipt of such notice; provided Seller may condition such approval on receipt of additional security and/or proof of adequate insurance from Consultant and any other person or entity performing any inspection at the Property. Seller or its representative may be present to observe any testing or other inspection performed on the Property. Buyer shall promptly deliver to Seller copies of all reports relating to the Environmental Assessment of the Real Property performed by the Consultant or its agents, employees or contractors and shall not deliver such reports to any other person or entity or to any governmental or quasi-governmental agency or authority. Buyer shall maintain, and shall ensure that the Consultant maintains, public liability and Property damage insurance in amounts and in form and substance adequate to insure against all liability of Buyer and its agents, employees and contractors, arising out of any entry or inspections of the Property pursuant to the provisions hereof, and Buyer shall provide Seller with evidence of such insurance coverage upon request by Seller. Buyer shall indemnify, reimburse and hold Seller harmless from and against any costs, damages, liabilities, losses, expenses, liens or claims (including, without limitation, reasonable attorneys’ fees and expenses) arising out of or relating to any inspection and/or testing activities performed by or on behalf of Buyer, including, without limitation, any personal injury, property damage or rental loss resulting from any entry on the Property by Buyer, Consultant, its agents, employees or contractors in the course of performing the Environmental Assessment on the Property. The foregoing obligations and indemnity set forth in this subparagraph (b) shall survive beyond Closing, or, if the purchase and sale is not consummated, beyond the termination of this Agreement. Buyer hereby agrees that the waiver or satisfaction of the condition set forth in Section 3.1 below shall constitute an acknowledgement that Seller has given Buyer every opportunity to perform an Environmental Assessment.

(c)

Seller agrees that it shall be responsible for remedying adverse environmental conditions identified by the Environmental Assessment, only to the extent provided in the immediately following two sentences. Seller may, at its option, either (a) arrange for and oversee the prescribed clean-up steps required to cure such adverse environmental conditions (the “Clean-Up”), or (b) provide Buyer with a credit against the purchase price (an “Environmental Credit”) for the estimated cost of the Clean-Up (as determined by a written estimate stated in the Environmental Assessment, or if not stated, to be obtained by the Consultant on behalf of the parties, and subject to the approval of both parties). In no event shall (i) Seller be

-113-

	required to expend in excess of $100,000.00 in respect of the cost of the Clean-Up, or (ii) the amount of the Environmental Credit required to be paid by Seller exceed $100,000.00 (the “Threshold Amount”). Notwithstanding the foregoing, should a prospective lender condition its Mortgage Commitment on the removal of certain storage tanks located on the Property, Seller shall undertake such removal, at Seller’s own expense.
(d)	SELLER DISCLAIMS THE MAKING OF ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, REGARDING THE PROPERTY OR MATTERS AFFECTING THE PROPERTY, INCLUDING, WITHOUT LIMITATION, THE PHYSICAL CONDITION OF THE PROPERTY, THE QUALITY OF ANY WORK OR MATERIALS USED IN CONNECTION WITH THE IMPROVEMENTS ON THE REAL PROPERTY, TITLE TO OR THE BOUNDARIES OF THE REAL PROPERTY, PEST CONTROL MATTERS, SOIL CONDITION, HAZARDOUS WASTE, TOXIC SUBSTANCE OR OTHER ENVIRONMENTAL MATTERS, COMPLIANCE WITH BUILDING, HEALTH, SAFETY, LAND USE AND ZONING LAWS, REGULATIONS AND ORDERS, STRUCTURAL AND OTHER ENGINEERING CHARACTERISTICS, TRAFFIC PATTERNS, THE DEVELOPMENT POTENTIAL OF THE PROPERTY AND THE PROPERTY’S USE, FITNESS, VALUE, OR ADEQUACY FOR ANY PARTICULAR PURPOSE, AND ALL OTHER INFORMATION PERTAINING TO THE PROPERTY. BUYER, MOREOVER, ACKNOWLEDGES THAT (I) BUYER HAS ENTERED INTO THIS AGREEMENT WITH THE INTENTION OF MAKING AND RELYING UPON ITS OWN INVESTIGATION OF THE STRUCTURAL CONDITION SURVEY, ENVIRONMENTAL, FINANCIAL AND LEGAL CONDITION OF THE PROPERTY, AND (II) BUYER SHALL PURCHASE THE PROPERTY IN ITS “AS-IS” AND “WHERE-IS” CONDITION ON THE CLOSING DATE.
(e)	Buyer its agents, employees, contractors, affiliates, successors and assigns, hereby releases and forever discharges Seller, its agents, affiliates, successors, assigns, Seller’s investment manager, partners and officers from any and all rights, claims and demands at law or in equity, whether direct or indirect, foreseen or unforeseen, or known or unknown at the time of this Agreement, which Buyer has or may have in the future, arising out of, or in any way connected with, the structural, survey, environmental, financial or legal condition of the Property, or any law or regulation applicable thereto.
(f)	Buyer hereby specifically acknowledges that Buyer has carefully reviewed this Section 2.3 and discussed its import with legal counsel and that the provisions of this Section 2.3 are a material part of this Agreement.

ARTICLE III

CONDITIONS PRECEDENT

Section 3.1	Conditions.  Notwithstanding anything in this Agreement to the contrary, Buyer’s obligation to purchase and Seller’s obligation to sell shall be subject to and contingent upon the satisfaction or waiver of the following conditions precedent:
(a)	Provided that all of the following shall have occurred: (i) Buyer shall have arranged for an Environmental Assessment of the Property to be performed during the Diligence Period; (ii) such Environmental Assessment results in findings of adverse environmental conditions at the Property which will cost in excess of the Threshold Amount to cure and (iii) Buyer shall have provided a copy of the Environmental Assessment and written estimate of the cost of the Clean-Up to Seller prior to the end of the Diligence Period, Seller shall have the right to cancel this Agreement in lieu of giving an Environmental Credit or performing the prescribed Clean-Up, upon written notice to Buyer within ten (10) days of receipt of the Environmental Assessment and written estimate of the cost of the Clean-Up of its intention to cancel this Agreement, this Agreement shall be deemed automatically cancelled, except as provided in the immediately following sentence. In the event Seller has elected to cancel this Agreement pursuant to the immediately preceding sentence, Buyer shall have the option, in Buyer’s sole discretion, to be exercised by written notice to Seller, received by Seller within ten (10) days of Buyer’s receipt of Seller’s cancellation notice, time being of the essence with respect to such date, to agree to proceed to Closing subject to the property being delivered on an “as-is” basis, as provided in Section 2.3(d) of this Agreement, including any adverse environmental conditions identified in the Environmental Assessment, and subject to an Environmental Credit in the Threshold Amount, in which event the Agreement shall not be cancelled and the Parties shall Close pursuant to this Agreement.
(b)	Provided that all of the following shall have occurred: (i) Buyer shall have promptly applied for financing in an amount not to exceed Three Million Seven Hundred and Three Thousand One Hundred and Twenty Five Dollars ($3,703,125.00), at prevailing interest rates, for a term not to exceed ten (10) years and subject to such terms and conditions as would typically apply to commercial mortgage financing in the metropolitan New York area; (ii) Buyer has made such application with at least two (2) commercial lenders and has used commercially reasonable efforts to comply with the requirements of such lenders; (iii) Buyer fails to secure a Mortgage Commitment by the last day of the Financing Period; and (iv) Buyer has provided evidence of such unsuccessful applications along with notice to Seller of its cancellation of this Agreement (a “Cancellation Notice”), this Agreement shall be deemed automatically cancelled.
(c)	Buyer shall immediately order a title insurance binder (the “Title Binder”) from Title Company. Promptly after receipt of the Title Binder from Title Company, Buyer shall (i) forward copies of the Title Binder to Seller’s attorneys and (ii) give written notice to Seller, with a copy of such notice to Seller’s attorneys, of objections to title other than the Permitted Encumbrances, if any, appearing in the Title Binder which Buyer has not herein agreed to take subject to, it being agreed by Buyer that Buyer will agree to accept title to the Property subject to the Permitted Encumbrances, and that failure to raise any such objections within 72 hours following both (i) receipt of

-115-

the Title Binder from the Title Company (which Buyer shall ensure has been simultaneously provided to Seller) and (ii) receipt of notice from Seller stating that Buyer must provide notice of title objections which it will not take subject to, shall be deemed a waiver by Buyer of any such objections. If Seller shall desire to remove such objections (it being understood that Seller shall be under no obligation to remove any objections, or to commence any action or proceeding, or to incur any expense in connection therewith, except that Seller agrees to pay and discharge all mortgages and other financial liens and encumbrances affecting the Property that it has voluntarily entered into), Seller shall be entitled to a reasonable adjournment of the Closing Date set forth herein, whereupon Seller shall have until such new closing date to dispose of any such objections, at no cost or expense to Seller. Any attempt by Seller to cure an objection shall not per se be construed as an admission by Seller that such objection is one that will give Buyer the right to terminate this Agreement. If Seller elects not, or is unable, to cure any such title objections, Buyer’s sole and exclusive remedies are to terminate this Agreement by sending a Cancellation Notice to Seller or to proceed to Closing with no abatement or reductions to the Purchase Price.

Section 3.2

Failure or Waiver of Conditions Precedent. In the event this Agreement shall be terminated pursuant to Section 3.1, this Agreement shall terminate, all rights and obligations hereunder of each party shall be discharged (except for the obligations and undertakings which pursuant to this Agreement shall survive the termination hereof), and Escrow Agent shall return the Deposit to Buyer plus any interest which may have accrued thereon, unless Buyer shall not have restored the Property pursuant to Section 2.3(b), in which event Escrow Agent shall first disburse to Seller the amount necessary to complete such restoration, and Buyer shall remain liable to pay to Seller any balance due in respect thereof. Buyer shall provide to Seller copies of all reports, studies and other information with respect to the Property generated by any third-party hired by Buyer. Buyer’s failure to send a Cancellation Notice pursuant to Section 3.1 on or before the end of the Diligence Period in the case of subsection (b), or within five (5) days of Seller’s notice to Buyer that Seller elects not to, or is unable to, cure any title objections in the case of subsection (c), time being of the essence with respect to each of such dates, shall constitute an agreement by Buyer to waive said contingencies and proceed to Closing pursuant to this Agreement. In any event, the Closing shall be deemed to constitute an irrevocable waiver by Buyer of any remaining unfulfilled conditions.

At the time of the Mortgage Commitment, Buyer shall deliver to Escrow Agent a certified or bank check or cash in the sum of One Hundred Thousand Dollars ($100,000), such amount together with the Deposit, to being referred to herein as the “Down Payment”). At Closing, Escrow Agent shall disburse the Down Payment and all interest which has accrued thereon, to Seller. In

In the alternative, if Seller is able to perform its obligations hereunder without being required to expend money in respect thereof (it being understood and agreed that Seller shall not be obligated to expend any funds other than its legal fees in connection with Closing), and if Buyer shall not have elected to terminate this Agreement, Buyer shall be entitled, as its sole and exclusive remedy, to sue for specific performance.
(b)	IF BUYER FAILS TO COMPLY WITH ITS OBLIGATIONS UNDER THIS AGREEMENT, FAILS TO CLOSE ON THE CLOSING DATE OR OTHERWISE COMMITS A DEFAULT HEREUNDER, SELLER, AT ITS OPTION, MAY TERMINATE THIS AGREEMENT WITHOUT NOTICE AND THEREUPON SELLER SHALL BE ENTITLED TO RETAIN THE DOWN PAYMENT AS LIQUIDATED DAMAGES (AND NOT AS A PENALTY) AND AS SELLER’S SOLE REMEDY AND RELIEF HEREUNDER (EXCEPT FOR THOSE OBLIGATIONS AND UNDERTAKINGS WHICH PURSUANT TO THIS AGREEMENT SHALL SURVIVE THE TERMINATION HEREOF). IN SUCH EVENT, ESCROW AGENT, IF IT HAS NOT PREVIOUSLY DONE SO, SHALL IMMEDIATELY DELIVER THE DOWN PAYMENT AND ALL INTEREST WHICH HAS ACCRUED THEREON TO SELLER AS LIQUIDATED DAMAGES UNDER AND IN CONNECTION WITH THIS AGREEMENT WITHOUT THE NECESSITY OF GIVING NOTICE TO BUYER AND NOTWITHSTANDING CONFLICTING INSTRUCTIONS FROM BUYER OR CONTRARY INSTRUCTIONS CONTAINED IN ESCROW AGENT’S GENERAL PROVISIONS. SELLER AND BUYER HAVE MADE THIS PROVISION FOR LIQUIDATED DAMAGES BECAUSE IT WOULD BE EXTREMELY DIFFICULT AND IMPRACTICABLE TO ASCERTAIN AND CALCULATE ON THE DATE HEREOF THE AMOUNT OF ACTUAL DAMAGES SUSTAINED BY SELLER FOR THE BREACH BY BUYER UNDER THIS AGREEMENT AND THE FAILURE OF THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR THE AMOUNT OF COMPENSATION SELLER SHOULD RECEIVE AS A RESULT OF BUYER’S BREACH OR DEFAULT, AND SELLER AND BUYER AGREE THAT THESE SUMS REPRESENT REASONABLE COMPENSATION TO SELLER FOR SUCH BREACH. NOTWITHSTANDING THE FOREGOING (I) IN THE EVENT OF ANY OTHER DEFAULT BY BUYER UNDER THIS AGREEMENT, SELLER SHALL HAVE ANY AND ALL RIGHTS AND REMEDIES AVAILABLE AT LAW OR IN EQUITY BY REASON OF SUCH DEFAULT, AND (II) THE PROVISIONS OF THIS SECTION 5.2(B) SHALL

NOT LIMIT OR AFFECT ANY OF BUYER’S INDEMNITIES AS PROVIDED IN OTHER SECTIONS OF THIS AGREEMENT.

(b)	Notwithstanding the foregoing, if Contract Period Damage occurs and the cost of repair, replacement or restoration of the Property as estimated by Seller exceeds One Hundred Thousand dollars ($100,000.00), either party may elect to terminate this Agreement by written notice to the other given not more than ten (10) days following the date that Seller notifies Buyer in writing of such damage, destruction or condemnation and assigns an estimated valuation thereto, but in no event later than the scheduled Closing Date. Upon termination of this Agreement pursuant to this paragraph, Seller shall cause Escrow Agent to return to Buyer the Down Payment and all rights and obligations hereunder of each party shall be at an end, except for those obligations and undertakings which pursuant to this Agreement shall survive the termination hereof. In the event neither party timely elects to terminate this Agreement pursuant to this subsection (b), the provisions of subsection (a) above shall be applicable.
(c)	Notwithstanding anything in this Agreement to the contrary, the insurance proceeds to be credited or delivered to Buyer pursuant to this Section 7.1 shall exclude business interruption or rental loss insurance proceeds, if any, allocable to the period through the Closing Date, which proceeds shall be retained by Seller.
(d)	This Section 7.1 shall be in lieu of the provisions contained in Section 5-1311 of the General Obligations Law.

ARTICLE VIII

MISCELLANEOUS

Section 8.1	Brokerage Commissions and Finder’s Fees. Each party to this Agreement warrants to the other that no person or entity, other than Schacker Real Estate Corp. and Park Place Realty Group, LLC (collectively, the “Broker”) is entitled to a real estate commission, real estate finder’s fee, real estate acquisition fee or other real estate brokerage-type compensation (collectively, “Real Estate Commission”) based upon the acts of that party with respect to the transaction contemplated by this Agreement. Each party to this Agreement hereby agrees to indemnify and defend the other against and to hold the other harmless from any and all loss, cost, liability or expense (including, but not limited to attorneys’ fees and returned commissions) resulting from any claim for Real Estate Compensation by any person or entity other than the Broker, based upon the acts of the indemnifying party. The provisions of this Section 8.1 shall survive Closing or, if the purchase and sale is not consummated, any termination of this Agreement. Seller agrees to pay Broker a Real Estate Commission pursuant to a separate agreement.
Section 8.2	Escrow Agent.
(a)	The parties acknowledge that Escrow Agent is acting solely as a stakeholder at their request and for their convenience, that Escrow Agent shall not be deemed to be the agent of either of the parties, and that Escrow Agent shall not be liable to either of the parties for any act or omission on its part unless taken or suffered in bad faith or involving gross negligence. Seller and Buyer shall jointly and severally indemnify and hold Escrow Agent harmless from and against all costs, claims and expenses, including reasonable attorneys’ fees, incurred in connection with the performance of Escrow Agent’s duties hereunder, except with respect to actions or omissions taken or suffered by Escrow Agent in bad faith or involving gross negligence on the part of Escrow Agent.
(b)	It is understood and agreed that Escrow Agent’s only duties and obligations hereunder are as expressly set forth in this Agreement. Escrow Agent shall have the right to consult with separate counsel of its own choosing (if it deems such consultation advisable) and shall not be liable for any action taken, suffered, or omitted by it in accordance with the advice of such counsel. Escrow Agent shall be protected in acting upon any written or oral communication notice, certificate, or instrument or document believed by it to be genuine and to be properly given or executed without the necessity of verifying the truth or accuracy of the same or the authority of the person giving or executing the same. In the event of a dispute between the parties relating to the Down Payment Escrow Agent may elect to deposit the Down Payment in any court of competent jurisdiction.
(c)	Upon disposing of the Down Payment in accordance with the provisions of this Agreement, Escrow Agent shall be relieved and discharged of all claims and liabilities relating to the Down Payment, and shall not be subject to any claims or surcharges made by or on behalf of either party hereto.
(d)	The fact that Escrow Agent is acting as such under this Agreement shall not in any way prevent it from representing Seller or any other party with respect to this

-122-

	Agreement, the transactions herein contemplated, and any litigation arising out of this Agreement.
Section 8.3	Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto, their successors and assigns, provided that Buyer may not assign its interest under this Agreement without the prior written consent of Seller, which consent Seller may give or withhold in its sole and absolute discretion.
Section 8.4	Notices.

Section 8.10	Confidentiality. The parties agree not to advertise or publish any information regarding this transaction until Closing. Buyer further agrees not to deliver or distribute to any third party any material received from Seller or Seller’s agents, employees, contractors, affiliates, successors or assigns or Buyer’s agents, affiliates, successors or assigns concerning the Property prior to Closing, provided that Buyer may deliver such material to its advisors, potential lenders and potential investors (to the extent reasonably necessary or appropriate for such investors to make their investment decisions), so long as such parties agree to maintain such material confidential and not to deliver such material to any third party. Buyer shall indemnify and defend Seller against and hold Seller harmless from any and all loss, cost, liability and expense (including reasonable attorneys’ fees and expenses) arising out of Buyer’s failure to keep any acquired information relating to the Property confidential in accordance with this Section 8.10. The provisions of this Section 8.10 shall survive the Closing Date and any termination of this Agreement.
Section 8.11	Exculpation. Seller and Buyer agree that their respective remedies shall be limited as set forth in Section 5.2 above.

The provisions of this Section 8.11 shall survive the Closing Date or any termination of this Agreement.

All oral or written prior statements, representations or promises, if any, and all prior negotiations and agreements are superseded by this Agreement and merged herein. If any term or provision of this Agreement or any application thereof shall be invalid or unenforceable, the remainder of this Agreement and any other application thereof shall not be affected thereby.

This Agreement and all disputes arising therefrom, shall be interpreted under, and governed by, the laws of the State of New York, and the parties hereto hereby submit to the jurisdiction of the federal and state courts located in the City of New York with respect to any litigation arising out of this Agreement and the transactions herein described.
