 STATEMENT OF THE AGREEMENT 
  
 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
  

Section 1.    The Transaction.  Seller agrees to sell and convey to Buyer, and Buyer agrees to purchase, pay for
and acquire from Seller, the Property for the Purchase Price specified in Section 2 and on the other terms and conditions set forth in this Agreement.

 (a)    Purchase Price and Payment. The purchase price to be paid to Seller by Buyer for the
Property is TEN MILLION FIFTY THOUSAND DOLLARS ($10,050,000.00) (which is to be adjusted for certain charges and credits as provided in this Agreement) (the “Purchase Price”). 
  
 (b)    Payment Terms. The Purchase Price shall be paid to Seller by Buyer as follows: 

 

	 	(i)	 	The sum of TWO HUNDRED THOUSAND DOLLARS ($200,000.00) (the “Deposit”) has been wired or paid in good funds by Buyer to the Escrow Agent (as hereinafter defined)
contemporaneous with execution of this Agreement. The Deposit shall be held by Escrow Agent and distributed as provided in §2(c). 

  

	 	(ii)	 	The Purchase Price, in the amount of TEN MILLION FIFTY THOUSAND DOLLARS ($10,050,000.00) (which is to be adjusted for the Deposit and certain charges and credits as provided in this
Agreement), shall be paid to Seller by Buyer at the Closing (as hereinafter defined) by wire transfer on the Closing Date (as hereinafter defined). 

  
 (c)    Deposit. The escrow agent hereunder shall be: Lawyers Title Insurance Corporation, Attn.:
Joel A. Stein, Esq., 25 Braintree Hill Office Park Suite 204 Braintree, Massachusetts 02184 (the “Escrow Agent”). The Deposit paid to Escrow Agent by Buyer shall be held by Escrow Agent in an interest bearing account, and except in the
event of failure to close this transaction by reason of Buyer’s breach, any 

  

 -2- 








 
interest accrued thereon shall belong to Buyer and shall be applied and disposed of as follows: 
  
 (i)    Closing. If the transaction for the purchase and sale of the Property is
closed by the Closing Date, then the parties agree that the Purchase Price (which is to be adjusted for certain charges and credits as provided in this Agreement) shall be paid by Buyer to Seller on the Closing Date as follows: 
  
 (a)    if the Buyer elects to apply the
Deposit (but not the interest thereon) to the Purchase Price, the Deposit (but not the interest thereon) shall immediately be paid to Seller by wire transfer as directed by Seller and the balance of the Purchase Price (which is to be adjusted for
certain charges and credits as provided in this Agreement) shall immediately be paid by Buyer to Seller by wire transfer as directed by Seller; or 
  
 (b)    if the Buyer elects not to apply the Deposit to the Purchase Price, an amount representing the full amount of
the Purchase Price, shall immediately be paid to Seller by wire transfer as directed by Seller (which is to be adjusted for certain charges and credits as provided in this Agreement), and the Escrow Agent shall pay to Buyer the Deposit by separate
wire or check. The interest shall be paid directly to Buyer by separate wire or check by the Escrow Agent, whether the Deposit is applied to the Purchase Price or not. 
  
 (ii)    Failure to Close. If this transaction is not closed by the Closing Date
due to Seller’s failure to perform, or if either party terminates this Agreement voluntarily as a matter of right hereunder, then Escrow Agent shall promptly refund and return to Buyer the Deposit and all interest thereon. If this transaction
is not closed by the Closing Date for any other reason, then Escrow Agent shall pay to Seller the Deposit and all interest thereon. 
  
 Section 3.     The Closing. At the closing (the “Closing”), Seller shall deliver to Escrow Agent a quitclaim deed
(the “Deed”) subject to the Permitted Encumbrances (as that term is defined below) for the Property and the other Closing Instruments (as hereinafter defined) and Buyer shall pay the Purchase Price as provided in Section 2 and deliver to
the Escrow Agent the Closing Instruments (as hereinafter defined) required to be delivered by Buyer. The Closing shall occur on July 24, 2003 at 10:00 A.M. (as may be extended in accordance with the terms hereof, the “Closing Date”) and

 (a)    Access to and Inspection of the Property. Buyer shall have the right, until July 14, 2003 at 5:00 P.M. EST (the “Due Diligence Expiration Date”) (such period being referred
to herein as the “Inspection Period”) to enter upon and have access to the Property, upon reasonable notice to Seller, in order to conduct surveys, tests, 

  

 -3- 








 
examinations, appraisals and inspections thereof; provided, that, any intrusive testing shall require Seller’s prior written consent, which consent
shall not be unreasonably withheld or delayed. Buyer shall not make any subsurface soil examinations unless Buyer has satisfied Seller that such examinations will not adversely affect any building foundations and/or utilities and until Buyer has
provided evidence of general public liability insurance with policy limits of $1,000,000 in personal injury coverage and $1,000,000 in property damage coverage naming Seller as an additional insured. At Seller’s option, Seller or Seller’s
agent may accompany and/or observe Buyer during Buyer’s due diligence undertakings at the Property. After having conducted such inspections and tests, Buyer shall immediately restore the Property to the same condition as existed prior to
Buyer’s entry thereon. Seller will provide Buyer with copies of all the documents listed on Exhibit 4(a) which Buyer may review during the Inspection Period. Seller shall during the Inspection Period promptly provide, or make available,
to Buyer in Seller’s office, financial records including income and expense records, invoices, accounts payable and accounts receivable reports from management, and other documents in Seller’s possession which relate exclusively to the
Property upon reasonable request from Buyer in writing. IT IS THE PARTIES EXPRESS UNDERSTANDING AND AGREEMENT THAT ALL SUCH MATERIALS ARE PROVIDED BY SELLER SOLELY FOR BUYER’S CONVENIENCE IN MAKING ITS OWN EXAMINATION AND DETERMINATION PRIOR TO
THE DUE DILIGENCE EXPIRATION DATE AS TO WHETHER IT WISHES TO PURCHASE THE PROPERTY, AND IN MAKING SUCH EXAMINATION AND DETERMINATION, BUYER SHALL RELY EXCLUSIVELY ON ITS OWN INDEPENDENT INVESTIGATION AND EVALUATION OF THE PROPERTY. EXCEPT WITH
REGARD TO CERTAIN ENVIRONMENTAL MATTERS AND REPORTS (AS TO WHICH SELLER’S REPRESENTATIONS IN SECTION 13(b) HEREOF SHALL APPLY). SELLER MAKES NO REPRESENTATION AS TO THE ACCURACY, COMPLETENESS OR RELEVANCY OF ANY MATERIALS PROVIDED BY SELLER.
Subject to the rights of Seller as party-in-possession, Buyer, and Buyer’s prospective mortgagee, shall also have the right subsequent to the Due Diligence Expiration Date to enter upon and have access to the Property upon reasonable notice to
Seller, in order to conduct surveys, approvals and inspections thereof; provided, however, Buyer shall have no right to terminate this Agreement as a result of any information or belief acquired at or in connection with such access and/or inspection
subsequent to the Due Diligence Expiration Date. 
  
 (b)    Indemnification for Inspections. Buyer shall indemnify, defend and hold Seller and Seller’s partners, employees, officers, agents, contractors, and representatives harmless from and against any lien,
liability, loss, damage, claim, fee, cost or expense, including reasonable attorney’s fees, for the costs of Buyer’s inspections, tests and investigations and for physical damage to property or bodily injury to persons which may have
resulted or may result from any such entry upon or inspection or testing of the Property by Buyer, or by any employee, officer, agent, contractor, representative or assignee of Buyer. This provision shall survive the termination of this Agreement
for any reason or delivery of the Deed, as applicable. Nothing contained in this Section 4(b) shall be deemed or construed to impose any responsibility on Buyer for any environmental conditions at the Premises or Property, except to the extent
caused or exacerbated by Buyer. 
  
 (c)    Due Diligence Expiration. If Buyer is not satisfied with the results of Buyer’s due diligence, with or without reason in Buyer’s sole discretion, Buyer may 

  

 -4- 








 
terminate this Agreement by written termination notice to Seller received on or before the Due Diligence Expiration Date, and this Agreement shall be
terminated and be of no further force and effect, except as otherwise provided herein. Any such termination notice shall be sufficient notice to the Escrow Agent to return the Deposit with interest accrued thereon to Buyer forthwith. If Buyer shall
fail to provide a termination notice to Seller received on or before the Due Diligence Expiration Date, then Buyer shall be deemed to have waived any objection as a result of Buyer’s due diligence, Buyer shall no longer be entitled to terminate
this Agreement as a result of its due diligence, and this Agreement shall continue in full force and effect. 
  
 (d)    Notice of Code Violation. Seller does hereby agree to give to Buyer, promptly upon receipt, a copy of any written notice
(the “Governmental Violation Notice”) which Seller receives prior to Closing from any governmental authority concerning a violation of any zoning or building code, law, statute, ordinance, rule, regulation or order which regulates the use
of the Property. If said Governmental Violation Notice is received by Seller on or before the Due Diligence Expiration Date, then Buyer shall have the right to terminate this Agreement on account of said violation. If said Governmental Violation
Notice is received by Seller after the Due Diligence Expiration Date but prior to the Closing Date, then, together with a copy of the Governmental Violation Notice, Seller shall give Buyer a written notice (the “Seller’s Violation Cure
Notice”) stating that: (i) Seller agrees to cure the violation identified in the Governmental Violations Notice either prior to Closing Date or as part of its responsibilities under the Lease (as that term is defined in Section 6(a)hereof) or
(ii) Seller does not agree to, or cannot, cure the violation in the Governmental Violation Notice. If Seller gives Buyer notice that Seller will cure the violation identified in the Governmental Violation Notice, then Seller shall proceed with due
diligence to effect such cure, and this transaction shall be closed on the Closing Date. If Seller notifies Buyer that Seller cannot or will not cure the violation identified in the Governmental Violation Notice, then provided such violation does
not pertain to the roof or structural elements of the Property or the Premises, Buyer shall have the right, at its option, to take either of the following actions: (x) Buyer may terminate this Agreement by written termination notice to Seller
received by Seller within five (5) days of delivery of Seller’s Violation Cure Notice; or (y) Buyer may proceed to close this transaction, in which event, Buyer shall waive Buyer’s objections and shall pay to Seller the full Purchase
Price. If Buyer fails to respond timely to Seller’s Violation Cure Notice, then Buyer shall be deemed to waive any objection on account of any violation, Buyer shall no longer be entitled to terminate this Agreement as a result of its
violation, and this Agreement shall continue in full force and effect. If such violation pertains to the roof or structural elements of the Property or the Premises, the parties shall proceed to Close the within transaction and Buyer shall cure the
same as provided in the Lease. 
  
 (e)    Condition of the Property. Buyer is purchasing the Property AS IS, WHERE IS, WITH ALL FAULTS. Buyer shall rely solely upon its own review of documents and inspections with regard to the condition of the
Property and the structural and mechanical systems of the improvements thereon, including, but not limited to, its location, size, subsurface or soil condition, construction and character; and, except as may be expressly set forth in this Agreement,
Buyer specifically agrees that it shall purchase and acquire the Property AS IS, WHERE IS, WITH ALL FAULTS WITHOUT ANY REPRESENTATION OR WARRANTY BY SELLER WHATSOEVER, WHETHER EXPRESS OR IMPLIED, AS TO THE TRUTH OR ACCURACY OF ANY 

  

 -5- 








 
DOCUMENTS SUPPLIED, AS TO THE CONDITION OF THE PROPERTY, OR AS TO ITS FITNESS FOR ANY PARTICULAR PURPOSE, ALL OF WHICH ARE HEREBY EXPRESSLY DISCLAIMED BY
SELLER. 
  
 (f)    Buyer hereby releases
Seller and its agent, representative and employees from any and all claims, demands, and causes of action, past and present which the Buyer may have relating to the condition of the Property at any time before the Date of the Closing providing that
in so doing Buyer does not and shall not be deemed by any party to have released Seller’s predecessor in title and the parties MetPath New England Inc., and Corning Life Sciences, Inc. from any responsibilities which said entities and their
successors and assigns may have pursuant to that certain Indemnity Agreement dated February 28. 1996 between MetPath New England, Inc and Corning Life Sciences Inc. and ADE Corporation. The provisions of this Section 4(f) shall survive the Closing.

  
 Section 5.    Title Matters and Insurance.

  
 (a)    Title Commitment. Buyer
shall obtain at its own expense, from a nationally recognized title insurance company selected by Buyer (the “Title Company”), a commitment for Title Insurance (the “Commitment”) for the issuance of an owner’s policy of
title insurance on a standard ALTA form (the “Policy”) with respect to the Property. Buyer shall obtain at Buyer’s expense such Survey of the Property as Buyer shall desire. Seller shall have no obligation to provide or pay for any
Title Commitment, title policy or survey Buyer may decide to obtain. 
  
 (b)    Title Matters and Encumbrances on Title. The Commitment shall show fee simple title to the Property in Seller, subject only to the following: (i) the standard exceptions for any owner’s policy, (ii)
those instruments and other title matters that are acceptable to Buyer (each of the matters described or referred to in items (i) and (ii) being herein referred to individually as a “Title Encumbrance”). Any Title Encumbrance which is
approved or is deemed to be approved or waived by Buyer shall be a permitted exception or encumbrance on the title to the Property and shall be added to the list of “Permitted Encumbrances”. Both parties agree that the Lease is a Permitted
Encumbrance. 
  
 (c)    Title Objection
Notice. On or before the Due Diligence Expiration Date, Buyer may give to Seller written notice (the “Title Objection Notice”) of any Title Encumbrance (other than a Permitted Encumbrance) which is not acceptable to Buyer as a
Permitted Encumbrance on the title to the Property (the “Title Objection”). Any Title Encumbrance affecting the Property not objected to in the Title Objection Notice from Buyer to Seller shall be deemed to be approved or waived by Buyer
and shall be a Permitted Encumbrance. If Buyer fails to provide a Title Objection Notice timely to Seller, then Buyer’s right to object on account of title shall be deemed waived, and all Title Encumbrances shall be Permitted Encumbrances.

  
 (d)    Title Cure Notice. If Buyer
timely provides to Seller a written Title Objection Notice, then, within five (5) days after the receipt of Buyer’s Title Objection Notice, Seller shall give to Buyer a written notice (the “Title Cure Notice”) stating that: (i) Seller
agrees to use reasonable efforts to cure one or more of the defects identified in the Title Objection Notice on or before the Closing Date, or (ii) Seller does not agree to 

  

 -6- 








 
or cannot cure one or more of the defects identified in the Title Objection Notice; it being understood and agreed that Seller shall not be obligated to cure
any defects. If Seller gives Buyer notice that Seller will use reasonable efforts to cure any of the Title Objections, then this transaction shall be closed on the scheduled Closing Date unless Seller notifies Buyer that it cannot effect the cure
before the scheduled Closing Date, in which event the Closing Date shall be extended for thirty (30) days to permit Seller to effect such cure.; provided Seller shall have no obligation for its failure to effect such cure. Notwithstanding the
foregoing, Seller shall be obligated to eliminate in connection with the Closing all mortgages and assignments of leases and rents, mechanic’s liens, tax liens (except for those which are not yet due and payable or for which prorations are
made), assessment liens (except for those which are not yet due and payable or for which prorations are made), judgment liens, mortgage liens, absolute and/or collateral assignments and other similar exceptions to the title to the Property which
affect Seller’s Interest (“Monetary Encumbrances”). Seller shall be entitled to use such portion of the Purchase Price as is necessary to pay off all such Monetary Encumbrances and any Title Objection that Seller agrees to use
reasonable efforts to cure. The Buyer hereby acknowledges that any instruments evidencing the release or discharge of the Monetary Encumbrances shall be recorded after the Closing in accordance with standard conveyancing practice. If Seller notifies
Buyer that Seller will not or cannot remove any Title Objection and/or Monetary Encumbrance, then Buyer shall have the right, at its option, to take either of the following actions: (x) Buyer may terminate this Agreement by written termination
notice to Seller received by Seller within five (5) days of delivery of Seller’s Title Cure Notice (or at the extended Closing Date); or (y) Buyer may proceed to close this transaction, in which event Buyer shall waive Buyer’s objections
and shall pay to Seller the full Purchase Price. 
  
 (e)    Title Fees. Buyer shall pay for the title search and for all premiums to the Title Company attributable to the issuance of the Commitment and the Policy. Buyer shall also pay any premium, if any,
attributable to special endorsements and affirmative coverages, and mortgagee’s policy of title insurance. 
  
 Section 6.    Tenants; Leases; and Service Contracts. 
  

(a)    Existing Tenants and Leases. It is a pre-condition to Buyer’s obligation to close this transaction that Buyer,
as landlord, and Seller as tenant, shall have entered into a lease for the entire Premises (the “Lease”) in accordance with the term sheet attached as Exhibit B. During the Inspection Period and subsequent to the expiration of the
Inspection Period, except for the lease described in the previous sentence, Seller shall not enter into any new leases for any portion of the Property. It is also a pre-condition to Buyer’s obligation to close this transaction that the Machine
Works Lease (as defined in Section 13(a)(iv) hereof) shall, as of the Closing Date, be converted into a sublease of the Lease. 
  
 (b)    Service Contracts. During the Inspection Period, Seller shall provide Buyer in writing evidence that there are no
service contracts affecting or pertaining to the Premises or the Improvements which will be binding on Buyer after Closing.

purchase price is paid. Each of Buyer and Seller does hereby agree to indemnify, defend and hold harmless the other party from and against any liability, cost or expense, plus all costs of collection, including litigation expenses and
attorneys’ fees, as a result of a claim for a commission, fee or other compensation made by any real estate broker, finder or other person and asserted against the other party by reason of an arrangement made or alleged to have been made by the

 (f)    Current Taxes. The tax adjustment shall be
based upon the number of days in the calendar year in which the Closing occurs, namely, on a per diem basis, and based upon the actual amount of real estate taxes, if known at the time of Closing. If the actual amount of real estate taxes is not
known at the time of the Closing, then the parties shall adjust the taxes based on the actual amount of real estate taxes for the prior year. Such prorations as described herein shall be re-adjusted by the parties as soon as the actual amount of
taxes are known, upon presentation of reasonable evidence thereof. This provision shall survive delivery of the Deed.

by written termination notice to the other party received within ten (10) days after Seller has given Buyer written notice of such loss or damage. If neither Seller nor Buyer elects to terminate this Agreement in accordance with the previous
sentence, or if the loss or damage would require an expenditure of less than Two Hundred Thousand Dollars ($200,000), then the parties shall proceed to close this transaction in accordance with the terms hereof except that Buyer shall receive an
assignment of any casualty loss insurance proceeds, if any, attributable to the loss or damage and Buyer shall receive a credit for the amount of the deductible required under Seller’s policy (subject, as to both the insurance proceeds and the
deductible, to a reduction equal to the amount if any expended by Seller to repair such loss or damage). 
  
 (b)    Appropriation. If appropriation proceedings should be commenced or threatened against the Property or if any
governmental or other authority should notify Seller of its intention to acquire the same pursuant to the power of eminent domain prior to the Closing Date, then Seller shall promptly thereafter give to Buyer written notice of such action. If the
estimated amount of the condemnation award for such appropriation is more than Two Hundred Thousand Dollars ($200,000), then either Buyer or Seller shall have the right at its option to terminate this Agreement by written termination notice to the
other party received within ten (10) days after Seller has given Buyer written notice of such condemnation. If neither Seller nor Buyer elects to terminate this Agreement in accordance with the previous sentence, then the parties shall proceed to
close this transaction; and in such event, Buyer shall have the right to negotiate with such governmental or other authority or to contest such appropriation in litigation proceedings, and shall be entitled to all proceeds thereof, which Seller
shall assign to Buyer as applicable, and Seller shall convey the Property subject to such proceedings and shall receive therefor the Purchase Price in full at the Closing. 
  
 Section 13.    Representations, Warranties and Indemnities. 
  
 (a)    Representation and Warranties of Seller.
Seller hereby makes the following representations and warranties to Buyer as of the date hereof which shall also be true and correct to Seller’s actual knowledge as of the Closing Date: 
  
 (i) Organization and Authority. Seller has been duly
organized and is validly existing under the laws of the State of Delaware and is duly authorized to transact business in the Commonwealth of Massachusetts. Seller has the 

  

 -11- 








 
full right and authority to enter into this Agreement and to transfer all of the Property and to consummate or cause to be consummated the transaction
contemplated by this Agreement. The person signing this Agreement on behalf of Seller is authorized to do so. Performance of this Agreement will not result in any breach of, or constitute any default under, or result in the imposition of a lien or
encumbrance on the Property under any agreement or other instrument to which Seller is a party or by which Seller or the Property might be bound. No consent or approval of any person or entity or of any governmental authority is required with
respect to the execution and delivery of this Agreement by Seller or the consummation by Seller of the transactions contemplated hereby or the performance by Seller of its obligations hereunder; 
  
 (ii)  Pending Actions. To Seller’s
actual knowledge, Seller has not received any written Governmental Violation Notice or written notice and has no actual knowledge of any action, suit, arbitration, unsatisfied order or judgment, government investigation or proceeding pending against
Seller or the Property which remains uncured except as set forth on Exhibit 13(a)(ii). 
  
 (iii)  Condemnation. To Seller’s actual knowledge, Seller has not received any written notice and has no actual
knowledge of any pending or threatened condemnation proceedings relating to the Property. 
  
 (iv)  Lease. To Seller’s actual knowledge, except for the Lease and the agreement entitled, “The ADE
Corporation Lease of Premises 80-82 Wilson Way, Westwood, Massachusetts to Massachusetts Machine Works, Inc. dated November 1, 1996” and all amendments thereto (the “Machine Works Lease”), there are no tenancy agreements of any type,
oral or written currently affecting the Property or which will be binding on the Property after the Closing. Seller agrees that it shall be responsible for obtaining and delivering to Buyer at Closing such documentation as may be required to convert
the Machine Works Lease into a sublease of the Lease. 
  
 (v)  Service Contracts. To Seller’s actual knowledge, there are no Service Contracts with regard to the Property which will be binding upon the Buyer after Closing. 
  
 (vi)  The representations and warranties of Seller
contained in this Section 13(a) shall survive the Closing Date for a period of one (1) year. 
  
 (b)    Environmental Warranties and Indemnities of Seller. The environmental reports listed on Exhibit 4(a) are all the environmental reports which Seller has in its possession with
regard to the Property, and Seller has delivered to Buyer a true, complete and accurate copy of each such report. There is a “pump and treat” facility on the Property, and Seller has delivered Buyer a true, accurate and complete copy of
all the information Seller has with regard to the conditions which gave rise to the installation of the pump and treat facility and the ownership and operation of the same. After the Closing, Seller shall cooperate (at no cost or expense to itself)
with Buyer in Buyer’s efforts to enforce the Indemnity Agreement dated February 28, 1996 between MetPath New England Inc., Corning Life Sciences Inc. and ADE Corporation 

  

 -12- 








 
to the extent the same is assigned to Buyer. The terms of this Section 13(b) shall survive the Closing. 
  
 (c)    Buyers’ Representation and Warranties.
Buyer hereby makes the following representations and warranties to Seller as of the date hereof and as of the date of the Closing: 
  
 (i)  Organization and Authority. Buyer has been duly organized and is validly existing under the laws of Delaware and at
closing shall be qualified to do business in the Commonwealth of Massachusetts. Buyer has the full right and authority to enter into this Agreement and to consummate or cause to be consummated the transaction contemplated by this Agreement. The
person signing this Agreement on behalf of Buyer is authorized to do so. No consent or approval of any person or entity or of any governmental authority is required with respect to the execution and delivery of this Agreement by Buyer or the
consummation by Buyer of the transactions contemplated hereby or the performance by Buyer of its obligations hereunder; 
  
 (ii)  Pending Actions. To Buyer’s actual knowledge, there is no action, suit, arbitration, unsatisfied order or
judgment, government investigation or proceeding pending against Buyer which, if adversely determined, could individually or in the aggregate interfere with the consummation of the transaction contemplated by this Agreement. 
  
 Section 14.    Voluntary Termination; Default; Remedies.

  
 (a)    Voluntary Termination;
Release of Liability. If this Agreement is voluntarily terminated by a party pursuant to a right of termination expressly provided in this Agreement then both parties shall, upon such voluntary termination, be automatically released from all
further obligations and liability under this Agreement, except as otherwise provided herein, and the Deposit and interest accrued thereon shall be returned to Buyer. 
  
 (b)    Default. The occurrence of any one or more of the following events shall constitute a
breach of a promise or obligation undertaken and thus a default by a party under this Agreement: (i) failure to close at the time and manner required under this Agreement, (ii) if any representation or warranty made by a party in or pursuant to this
Agreement was not true, correct, complete and accurate in any material respect as of the time it was made, or (iii) if any other promise or obligation undertaken by a party under this Agreement has not been performed within the time period specified
in this Agreement, or if no such time period has been so specified, within a period of ten (10) business days after the other party has given to the non-performing party written notice of such event. 
  
 (c)    Seller’s Remedies. If a default by
Buyer has occurred as provided in Section 14(b), then, in such event, Seller shall have the right (i) to terminate this Agreement by giving Buyer written notice of such termination, and (ii) to recover an amount equal to two times the Deposit as
Seller’s sole and exclusive right at law and in equity which shall be considered to be the equivalent of, and shall constitute, the payment of liquidated damages, with such amount and its payment being agreed upon 

  

 -13- 








 
by the parties as being a reasonable approximation of actual damages, including compensation to Seller for removing the Property from the market and
reimbursement for the costs and expenses incurred by Seller; and such application and disposition shall constitute a complete release of each party from its liability under this Agreement, except as otherwise provided herein. 
  
 (d)  Buyer’s Remedies. If a default by Seller has
occurred as provided in Section 14(b), then, in such event, Buyer shall have, as its sole and exclusive remedy at law and in equity, the right, at its option, to (x) obtain specific performance of this Agreement, but no actual, consequential, or
punitive damages; or (y) terminate this Agreement by giving Seller written notice of such termination, in which event the Deposit and all interest thereon shall be returned to Buyer. 
  
 Section 15.    General and Miscellaneous Provisions. 
  
 (a)  Notice. Any notice or other communication required or
permitted to be given to a party under this Agreement shall be in writing, unless otherwise specified in this Agreement, and shall be given by one of the following methods to such party at the address set forth at the end of this provision. The

 (b)    Complete Agreement; Amendment; Waiver; Counterparts. This Agreement, including the Preliminary Statements and all attached exhibits, constitute the complete and integrated agreement between the parties with
respect to the subject matter hereof and supersedes all previous negotiations and understandings, if any, between the parties; no oral or implied understanding, representation or warranty shall vary its terms. This Agreement may not be amended or
waived other than by a written instrument executed by the parties. This Agreement or any such amendment or waiver may be executed in several counterparts, each of which shall be considered a duplicate original and the same instrument. 
  
 (c)    Governing Law. This Agreement, the Closing
Instruments and any other applicable document, including all of the rights, obligations and liabilities of the parties thereunder, shall be governed, construed and enforced for all purposes in accordance with the laws of the Commonwealth of
Massachusetts, which is where the Property is located, without regard to its conflicts of laws and rules. 
  
 (d)    Severability. If any provision of this Agreement, the Closing Instruments or any other applicable document should be
held by a court to be invalid or unenforceable in any particular respect, then the remaining provisions of such document (or the same provision in any other respect) shall not be invalid, unenforceable, impaired or otherwise affected, but shall
continue to be in full force and effect; and to this end, all such provisions are hereby declared to be severable. 
  
 (e)    Successors and Assigns; Assignment. This Agreement shall inure to the benefit of and be binding upon the parties hereto
and their respective successors and permitted assigns. In general, a party shall not have the right to assign this Agreement or any interest herein without the prior written consent of the other party; provided, however, Buyer shall have the right
to assign this Agreement to an affiliate which the Buyer controls, without Seller’s prior written consent but such assignment and the assumption by such assignee of Buyer’s obligations hereunder shall not release Buyer from its obligation
or liability hereunder unless Seller shall have specifically agreed to the same. For purposes of this Section 15(e), a nominee trust in which Buyer or its affiliates own more than fifty percent (50%) of the beneficial interest shall be deemed an
affiliate which Buyer controls. Notwithstanding the foregoing, such assignment shall be void unless Buyer notifies Seller of such assignment on the earlier of (i) three (3) business days from the date of the assignment, or (ii) three (3) business
days prior to the Closing. Furthermore, either Seller and/or Buyer may assign its rights under this Agreement to a “qualified intermediary” in order to facilitate, at no cost or expense to the other, a like-kind exchange under Section 1031
of the Internal Revenue Code; provided, however, that (i) such assignment to a 

  

 -15- 








 
qualified intermediary shall not relieve either party of its respective obligations hereunder; and (ii) if Seller notifies Buyer that Seller has assigned its
rights under the Agreement to a qualified intermediary, Buyer will be deemed to have satisfied Buyer’s payment obligation if Buyer wires proceeds to the qualified intermediary or to any other entity as instructed by Seller. 
  
 (f)    Survival. No provision of this Agreement
survives delivery of the Deed, unless specifically indicated herein that a particular provision survives. 
  
 (g)    Time. Time is of the essence with respect to the performance of each provision of this Agreement. 
  
 (h)    Confidentiality. Buyer, Seller and Broker
shall maintain the confidentiality of the terms of this transaction and the contents of this Agreement, and all documents supplied to or obtained by Buyer in connection with its Due Diligence of the Property, and any related documents subject to
disclosure on a “need to know” basis to attorneys, clients, potential lenders, actual lenders, equity investors, accountants, architects, appraisers, engineers, contractors and consultants, or as required by applicable law or judicial
process. The parties expressly confirm that this Confidentiality provision is an essential and material term of this Agreement that is intended to be enforceable by any remedies available at law or equity, including injunctive relief. 
  
 (i)    Like-Kind Exchange. At Buyer’s request
and at no cost to Seller, Seller will agree to take all actions reasonably requested by Buyer in order to effectuate all or any part of the transactions contemplated by this Agreement as a like-kind exchange in accordance with Section 1031 of the
Internal Revenue Code including, without limitation, extending the Closing Date for up to thirty (30) days in the aggregate, and using a qualified intermediary. At Seller’s request, and at no cost to Buyer, Buyer will agree to take all actions
reasonably requested by Seller in order to effectuate all or any part of the transactions contemplated by this Agreement as a like-kind exchange in accordance with Section 1031 of the Internal Revenue Code including using a qualified intermediary.
Notwithstanding the aforementioned sentence, Seller shall have no right to extend the closing beyond the Closing Date set forth herein. 
  
 (j)    No Personal Liability. Buyer acknowledges and agrees that no general or limited partner, officer, director, equity
owner, employee, or representative of Seller shall ever have any personal liability under this Agreement. Seller acknowledges and agrees that no general or limited partner, officer, director, equity owner, employee or representative of Buyer shall
ever have any personal liability under this Agreement. 
  
 (k)    Construction. The parties hereto hereby acknowledge and agree that (i) each party hereto is of equal bargaining strength, (ii) each such party has actively participated in the drafting, preparation and
negotiation of this Agreement, (iii) each such party has consulted with such party’s own, independent counsel, and such other professional advisors as such party has deemed appropriate, relative to any and all matters contemplated under this
Agreement, (iv) each such party and such party’s counsel and advisors have reviewed this Agreement, (v) each such party has agreed to enter into this Agreement following such review and the rendering of such advice, and (vi) any rule of
construction to the effect that ambiguities are to be resolved against the 

  

 -16- 








 
drafting parties shall not apply in the interpretation of this Agreement, or any portions hereof, or any amendments hereto. 
  
 (l)    No Obligations to Third Parties. Except as
otherwise expressly provided herein, the execution and delivery of this Agreement shall not be deemed to confer any rights upon, nor obligate any of the parties hereto, to any person or entity other than the parties hereto. 
  
 (m)    Waiver. The waiver or failure to enforce
any provision of this Agreement shall not operate as a waiver of any future breach of any such provision or any other provision hereof. 
  
 (n)    Fees and Other Expenses. Except as otherwise provided herein, each of the parties hereto shall pay its own fees and
expenses in connection with this Agreement. 
  
 (o)    Computation of Time Periods. If the date upon which the Inspection Period expires, the Closing Date or any other date or time period provided for in this Agreement is or ends on a Saturday, Sunday or
federal, state or legal holiday, then such date shall automatically be extended until 5 p.m. Eastern Daylight Time of the next day which is not a Saturday, Sunday or federal, state or legal holiday.
