such approval not to be unreasonably withheld; Sellers failure to notify Purchaser of its disapproval shall be deemed to be Sellers disapproval thereof. In addition, Purchasers right to conduct the surveys, assessments, studies,
tests, inspections and examinations described above shall be subject to the condition that Purchaser shall first have provided Seller with a certificate of insurance evidencing Purchasers (or its contractors, agents or
representatives) procurement of the commercial general liability insurance coverages described below. Purchaser and its employees, agents and representatives shall not contact any Tenant without first obtaining Sellers prior consent

Purchaser, whereupon, except as expressly provided to the contrary in this Agreement, no party hereto shall have any other or further rights or obligations under this Agreement. Seller acknowledges that the sum of $25.00 is good and adequate

(Title Commitment) for the

issuance of an ALTA Form B owners policy of title insurance issued by Stewart Title Guaranty (the Title Insurer) in the amount of the Purchase Price, showing title in the
Sellers name, with extended coverage over the so-called general or standard exceptions arising from the actions of Seller but not any Tenant which are a part of the printed form of the policy, and including the following endorsements

Protection Lien, Gap, Restrictions (as applicable) and Encroachment (as applicable), together with a true, correct and complete copy of every document and instrument of record reflected therein. If Purchaser objects to any exceptions to title shown
in any Title Commitment, Purchaser shall give Seller notice of such objection within ten (10) business days following Purchasers receipt of such Title Commitment and all such documents and instruments of record. Any exceptions to title
shown on the Title Commitment to which Purchaser does not so object shall be Permitted Exceptions; provided, however, that in no event shall the Permitted Title Exceptions include, and Purchaser shall not be required to notify Seller of
its objection to, any mortgage, deed of trust or financing statement relating thereto that encumbers the Property or any tax, mechanics lien or judgment lien relating to or arising from the acts of Seller but not any Tenant. If the Title
Commitment discloses exceptions to title other than Permitted Exceptions and liens securing indebtedness of a definite and ascertainable amount which will be released on the Date of Closing by Seller, Seller shall have five (5) business days
from the date of Purchasers notice of objection to have such exceptions removed from the Title Commitment (or, with the consent of Purchaser, to have the Title Insurer commit to insure for the full amount of said policy against loss or damage
that may be occasioned by such unpermitted exceptions) and provide evidence thereof to Purchaser, and, if Seller fails to have such exceptions removed (or with the consent of Purchaser insured over), Purchaser may elect, on or before the date of
Closing, as its sole remedy with respect to such matters (i) to terminate this Agreement, in which event this Agreement shall be null and void and neither party shall have any rights or obligations hereunder except those that expressly survive
such termination, or (ii) to accept title subject to such unpermitted exceptions with the further right of to pay at Closing the existing first mortgage indebtedness secured by the Property, and cause the Title Insurer to issue its endorsement
insuring against damage caused by any such unpermitted exceptions caused by Seller after the Effective Date and require Seller to pay at Closing the cost of the premiums and security provided for said endorsement. On the date of Closing, Seller
shall cause the Title Insurer to issue an owners title insurance policy or prepaid commitment therefor, pursuant to and in accordance with the Title Commitment, insuring fee simple title in the Purchaser as of the date of Closing, subject only
to the Permitted Exceptions.

(b) Survey.    No later than five (5) business
days following the Effective Date, Seller shall obtain and deliver, at Sellers sole cost and expense, an as-built survey of the Property dated no earlier than one hundred eighty (180) days prior to the date of Closing, prepared by a
surveyor licensed by the state of the Property and certified to Purchaser, the Title Insurer and such other parties as Purchaser shall designate, to be prepared in accordance with the Land Title Surveys of American Land Title Association National

ten (10) business days following Purchasers receipt of the Survey, and Seller shall have five (5) business days from the date of such notice to have such encroachments, violations, unpermitted exceptions or other matters so objected
to by Purchaser removed or, with the consent of Purchaser, insured over by the Title Insurer and provide evidence thereof to Purchaser, and if Seller fails to have the same removed or, with the consent of Purchaser, insured over, Purchaser may
elect, on or before the date of Closing, as its sole remedy with respect to such matters, (i) to terminate this Agreement, in which event this Agreement shall be null and void and neither party shall have any rights or obligations hereunder
except those that expressly survive such termination, or (ii) accept the Property subject to such encroachments, violations or unpermitted exceptions with the further right to cause the Title Insurer to issue its endorsement insuring against
damage caused by any such encroachments, violations or unpermitted exceptions caused by Seller after the Effective Date and require Seller to pay at Closing the cost of the premiums provided for said endorsement.

8.      Representations and Warranties of Seller.    Seller
hereby makes the following representations and warranties to Purchaser, each of which shall be deemed material:

(a)      Leases.    Attached hereto as Exhibit D is a complete list setting forth all leases in effect relating to the
Property and all modifications and amendments to such leases (such leases, as modified and amended, being herein collectively referred to as the Leases or individually as Lease). Seller has delivered to Purchaser complete and
accurate copies of all of the Leases. Seller is the landlord under all of the Leases and owns unencumbered legal and beneficial title to all of the Leases and the rents and other income thereunder, subject only to the collateral
assignment of the Leases and rents thereunder in favor of the holder of an existing mortgage or deed of trust encumbering the Property, which mortgage or deed of trust shall be cancelled and satisfied by Seller at the Closing. The lessees or tenants
identified in the Leases are hereinafter collectively referred to as Tenants or individually as Tenant. To the best of Sellers knowledge, there are no existing or uncured defaults by any Tenant or Seller under the
Leases. No Tenant has prepaid rent for more than the current month under such Tenants Lease, or is entitled to any special work (not yet performed) or consideration (not yet given) in connection with its tenancy, except for a tenant
improvement allowance of $617,380 owed to BFS (the BFS Allowance) and any improvements or allowances in connection with BFS election to expand its premises. All commissions currently due and payable under, relating to, or as a
result of the Leases have been cashed-out and paid and satisfied in full by Seller or by Sellers predecessor in title to the Property, and no further commissions shall be due or payable as a result of any Lease or any extension of the term of
any Lease or any expansion of the space leased thereunder pursuant to any option contained in any Lease except as disclosed on Exhibit E.

(b)      Contracts.    Attached hereto as
Exhibit E is a complete and accurate list and description of all written or oral (i) service, maintenance, operating, repair, collective bargaining, employment, employee benefit, management, leasing, brokerage, supply,
purchase, consulting, professional service, advertising, promotion, public relations, construction contracts and commitments, and equipment warranties (excluding the Leases)

which have been entered into by or are binding upon Seller or the Property; (ii) equipment leases; and (iii) guarantees and warranties which benefit Seller in effect with respect to the
Property or any portion thereof. (said agreements being herein collectively referred to as the Contracts). Seller has provided Purchaser with complete and accurate copies of all Contracts. All such Contracts are in full force and effect
in accordance with their respective provisions, all payments required to be made by Seller or the Owner thereunder have been paid in full, and, to the best of Sellers knowledge, there is no default, or claim of default, or any
event which the passage of time or notice, or both, would constitute a default on the part of any party to any of such Contracts. All such Contracts are terminable without penalty or obligation to pay any severance or similar compensation on no more
than thirty (30) days notice, except as expressly set forth on Exhibit E. Seller agrees to cancel, effective no later than the Closing, any of the Contracts terminable without penalty or obligation to pay any
severance or similar compensation on no more than thirty (30) days notice specified by Purchaser in a written notice to Seller given at least ten (10) days prior to the Closing. Seller has cancelled or will cancel, effective as of
the Closing, any agreement in the nature of a management agreement or service contract between Seller and any partner or member of Seller or any party affiliated with or related to Seller or any partner or member of Seller.

(c)      No Litigation.    There are no actions,
suits, or proceedings pending, or, to the best of Sellers knowledge, threatened by any organization, person, individual, or governmental agency against Seller with respect to the Property or against the Property, nor does Seller know of any
basis for such action. Seller also has no knowledge of any pending or threatened application for changes in the zoning applicable to the Property or any portion thereof.

(d)      Condemnation.    No condemnation or
other taking by eminent domain of the Property or any portion thereof has been instituted and, to the best of Sellers knowledge, there are no pending or threatened condemnation or eminent domain proceedings (or proceedings in the nature or in
lieu thereof) affecting the Property or any portion thereof or its use.

(e)      No Roll-Back Taxes.    The Property has
not been classified under any designation authorized by law to obtain a special low ad valorem tax rate or to receive a reduction, abatement or deferment of ad valorem taxes which, in such case, will result in additional, catch-up or
roll-back ad valorem taxes in the future in order to recover the amounts previously reduced, abated or deferred.

(f)      Compliance with Applicable Laws.    Seller has not received any written notice of any alleged violation of or nonconformity with any law
relating to, or any restriction, condition, covenant, commitment, contract or agreement concerning, the ownership, operation, use and/or occupancy of the Property that has not been heretofore corrected.

(g)      Operating Expense Statement.    Seller
has delivered to Purchaser an Operating Expense Statement prepared on a cash basis which is a complete, true, and

accurate list and description of all income received and all operating expenses paid during the period from January 1, 2007 through August 31, 2010.

(h)      Employees.    There are no employment,
collective bargaining, or similar agreements or arrangements between Seller and any of its employees or others which will be binding on Purchaser or any of Purchasers successors in title.

(i)      Effect of Certification.    Neither this
Agreement nor the transactions contemplated herein will constitute a breach or violation of, or default under, or will be modified, restricted, or precluded by the Leases, the Contracts, or the Permitted Exceptions.

(j)      Authorization.    Seller is a duly
organized and validly existing limited liability company under the laws of the State of Illinois. This Agreement has been duly authorized and executed on behalf of Seller, all necessary action on the part of Seller to authorize the transactions
herein contemplated has been taken, and no further action is necessary for such purpose, and this Agreement constitutes the valid and binding agreement of Seller, enforceable in accordance with its terms, subject to bankruptcy, insolvency and
similar laws affecting generally the enforcement of creditors rights. Neither the execution and delivery of this Agreement nor the consummation of the transaction contemplated hereby will (i) be in violation of Sellers Articles of
Organization or Operating Agreement, (ii) conflict with or result in the breach or violation of any law, regulation, writ, injunction or decree of any court or governmental instrumentality applicable to Seller, or (iii) constitute a breach
of any evidence of indebtedness or agreement of which Seller is a party or by which Seller is bound.

(k)      Seller Not a Foreign Person.    Seller is not a foreign person which would subject Purchaser to the withholding tax provisions
of Section 1445 of the Internal Revenue Code of 1986, as amended.

(l)      Licenses.    To Sellers knowledge,
Exhibit F contains a complete list of all licenses issued by any governmental authority and relating to the Sellers (and not any tenants) operation, ownership and maintenance of the Property or any part thereof
including elevator permits, and machinery permits (the Licenses). Neither Seller nor any of its agents or employees has received notice (i) of any intention on the part of the issuing authority to cancel, suspend or modify any of
the Licenses or to take any action or institute any proceedings to effect such a cancellation, suspension or modification or (ii) that Seller fails to hold any license, franchise, certification, authorization, approval or permit required by any
governmental or quasi-governmental authority for the use and operation of the Property by Seller as the same is presently used and operated.

At Closing, Seller shall represent and warrant to Purchaser that all such representations and warranties of Seller in this Agreement remain true and correct as of the date of the Closing, except for any
changes in any such representations or warranties that occur and are disclosed by Seller to Purchaser expressly and in writing at any time and from time to time prior to Closing upon their occurrence, which disclosures shall thereafter be updated by
Seller to the date of Closing. Each and

all of the express representations and warranties made and given by Seller to Purchaser herein shall survive the execution and delivery of the Special Warranty Deed by Seller to Purchaser for a
period of one (1) year after the Closing, except to the extent that a notice of breach of any representation or warranty has been given prior to such expiration. If there is any change in any representations or warranties and Seller does not
cure or correct such changes prior to Closing, then Purchaser may, at Purchasers option, and as its sole remedy with respect to such matters (i) close and consummate the transaction contemplated by this Agreement, except that after such
closing and consummation Purchaser shall have the right to seek monetary damages from Seller for any such changes willfully caused by Seller after the Effective Date or any such representations or warranties willfully breached by Seller, or
(ii) terminate this Agreement by written notice to Seller, whereupon the Earnest Money shall be immediately returned to Purchaser, and thereafter the parties hereto shall have no further rights or obligations hereunder, except only (1) for
such rights or obligations that, by the express terms hereof, survive any termination of this Agreement and (2) that Purchaser shall have the right to seek monetary damages from Seller for any changes in such representations and warranties
willfully caused by Seller after the Effective Date or any such representations and warranties willfully breached by Seller.

---

total sum of all cash security deposits paid by Tenants under Leases and not theretofore applied to delinquent rent and other charges payable by the applicable Tenant. Seller shall deliver to
Purchaser at Closing any security deposit which is in a form other than cash. In either case, Purchaser shall assume all responsibility for the security deposits from and after the Closing and Seller shall have no further liability or responsibility
therefor. Seller hereby acknowledges that Purchaser shall not be legally responsible to Seller for the collection of any uncollected rent or other income under any of the Leases that is past due or otherwise due and payable as of the date of
Closing. Purchaser will make a reasonable good faith effort (without any obligation to expend money) after the Closing to collect such delinquent rents in the ordinary course of Purchasers operation of the Property. Purchaser agrees that if
(i) a Tenant is in arrears on the date of Closing in the payment of rent or other charges under such Tenants Lease, and (ii) upon Purchasers receipt of any rental or other payment from such Tenant, such Tenant is, or after
application of a portion of such payment will be, current under such Lease in the payment of all accrued rental and other charges that become due and payable on the date of Closing or thereafter and in the payment of any other obligations of such
Tenant to Purchaser, then Purchaser shall refund to Seller, out of and to the extent of the portion of such payment remaining after Purchaser deducts therefrom any and all sums due and owing it from such Tenant from and after the date of Closing, an
amount up to the full amount of any arrearage existing on the date of Closing.

(b)      Property Taxes.    Seller shall pay all
Taxes (as defined below) on the Property payable prior to the Closing and Purchaser shall be responsible for all Taxes on the Property payable on or after the Closing. Taxes payable in 2010 shall be prorated as of the date of Closing based on the
actual number of days in the calendar year of Closing and Seller shall receive a credit at Closing for the period from the date of Closing to the last day of the year. As used herein, the term Taxes shall mean any and all City, state,
county, and school district ad valorem taxes based on the ad valorem tax bills for the Property, if then available, or if not, then on the basis of the latest available tax figures and information. In addition, if after Closing there is an
adjustment or reassessment by any governmental authority with respect to, or affecting, any Taxes for the Property payable in the year of Closing or any prior year, any additional tax payment for the Property required to be paid in the year of
Closing shall be prorated between Purchaser and Seller and any such additional tax payment for the Property for any year prior to the year of Closing shall be paid by Seller. Subject to the rights of the Tenants under the Leases, Seller shall be
entitled to any and all refunds of Taxes attributable to periods for which Seller or its predecessors paid the Taxes. In the event any certiorari or similar proceeding of Seller relating solely to a period prior to the date of Closing continues or
is pending after the date of Closing, upon notice to Seller, Purchaser shall be entitled to prosecute or settle such proceeding on Sellers behalf. This agreement shall expressly survive the Closing.

of midnight preceding the date of Closing and pay their respective shares of all utility bills received subsequent to Closing (if they include a service period prior to the date of Closing),
which agreement shall survive Closing. Seller shall be entitled to all deposits presently in effect with the utility providers. If the relevant utility credits Purchasers account with the amount of any prepaid deposits previously made by
Seller, at Closing, Purchaser shall succeed to the ownership of, and the Purchase Price shall be adjusted by, the amount of any and all such deposits for such utilities.

(d)      Contracts.    Charges under the
Contracts shall be prorated as of Midnight preceding the date of Closing.

(e)      Other Tenant Charges.    At Closing
Seller shall deliver to Purchaser all expense deposits collected from Tenants (other than any relating to Taxes) for the year in which the Closing occurs less only the amount of expenses for such year actually paid by Seller (including those sums
properly paid the property manager). Seller shall be responsible for preparing any required expense or Tax pass through reconciliation for each calendar year prior to the calendar year in which the Closing occurs, and if Seller owes any Tenant any
funds for the period, Seller shall forthwith pay the same to Purchaser for reimbursement to the Tenant. Purchaser shall be responsible for preparing any required expense or Tax pass through reconciliation for the calendar year in which the Closing
occurs. Purchaser shall use commercially reasonable efforts to bill Tenants in accordance with their respective Leases for expense or Tax pass throughs for the period of the current calendar year during Sellers ownership and upon receipt of
the same from Tenants shall reimburse Seller for Sellers proportionate share based on the expenses or Taxes for the respective periods of ownership. Upon Purchaser completing the reconciliation, if Seller owes any Tenant any funds for the
period of its ownership, Seller shall forthwith pay the same to Purchaser for reimbursement to the Tenant.

(f)      Prepaid Insurance.    Seller shall not transfer to Purchaser any insurance policies or coverage and Purchaser shall make its own
arrangements for all insurance.

and Unpaid Commissions.    Seller shall pay all leasing commissions in connection with any Lease executed before the Effective Date and Purchaser shall pay (or reimburse Seller if previously paid by Seller) all leasing
commissions in connection with any Lease executed on or after the Effective Date (including leasing commissions attributable to the exercise by the Tenants of any expansion or extension options set forth in the Lease which are not exercised until on
or after the Effective Date). Purchaser shall be entitled to a credit against the Purchase Price for the total sum of any remaining improvement allowances under Leases executed prior to the Effective Date, the payment of which may become the
obligation of the landlord or lessor under the Leases after the Closing, but Purchaser shall receive no such credit against the Purchase Price for (i) the BFS Allowance (ii) any improvement allowances payable by the landlord or lessor
under the Leases as a result of the exercise by a Tenant on or after the Effective Date of any expansion or extension option in such Tenants Lease. Seller shall

receive a credit for the $91,975 improvement allowance paid to Bridgestone Retail Operations, LLC with respect to its expansion into Suite 115.

16.      Purchasers Default.    Except as provided in this
Paragraph 16, in the event of default by Purchaser under the terms of this Agreement, Sellers sole and exclusive remedy shall be to receive the Earnest Money as liquidated damages and thereafter the parties hereto shall have no further rights
or obligations hereunder whatsoever. It is hereby agreed that Sellers damages will be difficult to ascertain and that the Earnest Money constitutes a reasonable liquidation thereof and is intended not as a penalty, but as fully liquidated
damages. Seller agrees that in the event of a default by Purchaser, it shall not initiate any proceeding to recover damages from Purchaser, but shall limit its recovery to the receipt and retention of the Earnest Money. The limitations on
Purchasers liability under this Paragraph 16 shall be inapplicable to the liability of Purchaser for payments, if any, due by Purchaser to Seller under Paragraphs 4, 15, 22 and 29 hereof. However, the foregoing provisions of this
Paragraph 16 shall not be deemed to prohibit or limit Sellers right to seek actual, compensatory damages, post-Closing, with respect to Purchasers breach of Purchasers representations or warranties under this Agreement, and shall
not be deemed to prohibit or limit Sellers right to seek damages, the remedy of specific performance (other than the right to seek specific performance of the purchase itself), injunction or other appropriate relief with respect to any breach
of Purchasers obligations under Paragraph 15 or under any provision of this Agreement pursuant to which Purchaser has agreed to indemnify, defend, or hold harmless Seller, its affiliates and/or successors for any matters.

17.      Sellers Default.    In the event of default by
Seller under the terms of this Agreement, except as otherwise specifically set forth herein, at Purchasers option: (i) Purchaser may terminate this Agreement by written notice to Seller, receive the return of the Earnest Money and recover
from Seller its actual out-of-pocket costs not to exceed One Hundred Thousand Dollars ($100,000), whereupon the parties hereto shall have no further rights or obligations hereunder whatsoever, except for those rights and obligations which by their
terms expressly survive any such termination, (ii) enforce specific performance of Sellers obligations to execute and deliver to Purchaser the documents required to transfer and convey the Property to Buyer and otherwise perform all of
its obligations under this Agreement (together with recovery of all costs and attorneys fees incurred in connection with such lawsuit), or (iii) waive the breach and proceed with Closing. The foregoing provisions of this Paragraph 17
shall not be deemed to prohibit or limit Purchasers right to seek actual, compensatory damages, post-Closing, with respect to Sellers breach of Sellers representations or warranties under this Agreement. Except for payments, if
any, due by Seller to Purchaser under Paragraphs 15, 22 and 29 hereof, the parties hereto hereby agree that Sellers aggregate liability for any actual or alleged default or breach of this Agreement and the conveyance documents to be delivered
by Seller pursuant hereto shall not exceed Seven Hundred Fifty Thousand Dollars ($750,000).

18.      Condemnation.    If, prior to the Closing, all or any
part of the Property is subjected to a bona fide threat of condemnation by a body having the power of eminent domain or is taken by eminent domain or condemnation (or sale in lieu thereof), or if Seller has received notice that any condemnation
action or proceeding with respect to the Property is contemplated by a body having the power of eminent domain, Seller shall give Purchaser immediate written notice of such



19



---

threatened or contemplated condemnation or of such taking or sale, and Purchaser may by written notice to Seller given within thirty (30) days of the receipt of such notice from Seller,
elect to cancel this Agreement. If Purchaser chooses to cancel this Agreement in accordance with this Paragraph 18, then the Earnest Money shall be returned immediately to Purchaser and the rights, duties, obligations, and liabilities of the
parties hereunder shall immediately terminate and be of no further force and effect except those that expressly survive such termination. If Purchaser does not elect to cancel this Agreement in accordance herewith, this Agreement shall remain in
full force and effect and the sale of the Property contemplated by this Agreement, less any interest taken by eminent domain or condemnation, or sale in lieu thereof, shall be effected with no further adjustment and without reduction of the Purchase
Price, and at the Closing, Seller shall assign, transfer, and set over to Purchaser all of the right, title, and interest of Seller in and to any awards that have been or that may thereafter be made for such taking. At such time as all or a part of
the Property is subjected to a bona fide threat of condemnation and Purchaser shall not have elected to terminate this Agreement as hereinabove provided, Purchaser shall be permitted to participate in the proceedings as if Purchaser were a party to
the action. Seller shall not settle or agree to any award or payment pursuant to condemnation, eminent domain, or sale in lieu thereof without obtaining Purchasers prior written consent thereto in each case.

19.      Damage or Destruction.    If any of the Improvements
shall be destroyed or damaged prior to the Closing, and if either the estimated cost of repair or replacement exceeds Two Hundred Fifty Thousand Dollars ($250,000.00) or the damage results in the termination of one or more of the Leases, Purchaser
may, by written notice given to Seller within twenty (20) days after receipt of written notice from Seller of such damage or destruction, elect to terminate this Agreement, in which event the Earnest Money shall immediately be returned to
Purchaser and the rights, duties, obligations, and liabilities of all parties hereunder shall immediately terminate and be of no further force or effect except those that expressly survive such termination. If Purchaser does not elect to terminate
this Agreement pursuant to this Paragraph 19, or has no right to terminate this Agreement (because the damage or destruction does not exceed Two Hundred Fifty Thousand Dollars ($250,000.00) and has not resulted in the termination of one or more
of the Leases), and the sale of the Property is consummated, Purchaser shall be entitled to receive all insurance proceeds paid or payable to Seller by reason of such destruction or damage under the insurance required to be maintained by Seller
pursuant to Paragraph 10 hereof (less amounts of insurance theretofore received and applied by Seller to costs actually incurred for restoration). Seller shall not settle or release any damage or destruction claims without obtaining
Purchasers prior written consent in each case. All said insurance proceeds received by Seller by the date of Closing shall be paid by Seller to Purchaser at Closing, together with the lesser of (iii) that amount necessary to cover any
difference between the amount of such proceeds and the estimated cost of repair or replacement, or (iv) the amount of the deductible under Sellers property damage insurance policy. In addition, at Closing, Seller shall pay over to
Purchaser, and assign to Purchaser, all proceeds of any rent loss insurance for the period of time commencing on the date of Closing, if any. If the amount of said casualty or rent loss insurance proceeds is not settled by the date of Closing,
Seller shall execute at Closing all proofs of loss, assignments of claim, and other similar instruments in order that Purchaser receive all of Sellers right, title, and interest in and under said insurance proceeds.

21.      Assignment.    This Agreement and Purchasers
rights, duties, and obligations hereunder may not be delegated, transferred, or assigned by Purchaser without the prior written consent of Seller, and any assignee or transferee proposed by Purchaser shall expressly assume all of Purchasers
duties, liabilities and obligations under this Agreement by written instrument delivered to Seller. Notwithstanding the foregoing to the contrary, this Agreement, and Purchasers rights and duties hereunder, may be freely assigned and

28.      General Provisions.    No failure of either party to
exercise any power given hereunder or to insist upon strict compliance with any obligation specified herein, and no custom or practice at variance with the terms hereof, shall constitute a waiver of either partys right to demand exact
compliance with the terms hereof. This Agreement contains the entire agreement of the parties hereto, and no representations, inducements, promises, or agreements, oral or otherwise, between the parties not embodied herein shall be of any force or
effect. Any amendment to this Agreement shall not be binding upon the parties hereto unless such amendment is in writing and executed by all parties hereto. The provisions of this Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective heirs, legal representatives, successors, and assigns. Time is of the essence of this Agreement. This Agreement may be executed in multiple counterparts, each of which shall constitute an original, but all of

paragraph. The exhibits attached to this Agreement are an integral part of this Agreement and are hereby incorporated herein by this reference. This Agreement shall be construed and interpreted under the laws of the State of Illinois. Except as

any release to the public of information with respect to the sale contemplated herein or any matters set forth in this Agreement will be made only in the form approved by Purchaser and Seller. The provisions of this Section 10.2 shall survive
the Closing or any termination of this Agreement.

31.      Sellers
Post-Closing Obligations.    As security for Sellers post-closing obligations under this Agreement, at Closing Seller shall deposit into a joint order escrow account (the Post-Closing Escrow) the sum of
$750,000 to be held by Escrow Agent. The Post-Closing Escrow shall provide that if Purchaser claims that Seller owes Purchaser any amount pursuant to or arising out of a breach of this Agreement it may send a request for payment to the escrow holder
(a Post-Closing Claim). The escrow holder will deliver a copy of the Post-Closing Claim to Seller. If Seller does not sent a notice disputing the Post-Closing Claim within ten (10) days of receipt, then the escrow holder shall pay
the amount of the request. If Seller does send a notice disputing the
