SECTION 4: TITLE AND SURVEY

4.1 Delivery of Title Commitment. Within five (5) business days after the Date of this Agreement, Seller shall, at Seller’s sole cost, cause to be ordered a preliminary report or title commitment issued by the Title Company (the “Title Commitment”), covering the Property, together with copies of all documents referenced in the Title Commitment. Promptly following receipt of the Title Commitment, Seller shall deliver copies of same to Purchaser. Purchaser shall be entitled, during the initial Due Diligence Period to obtain a survey of the Property at its sole expense (the “Survey”).

4.2 Title Review and Cure. Purchaser shall have until ten (10) business days after its receipt of the Title Commitment (the “Title Review Period”) to review title to the Property as disclosed by the Title Commitment and the Survey. Purchaser shall have until the expiration of the Title Review Period, to notify Seller, in writing, of such objections as Purchaser may have to anything contained in the Title Commitment or the Survey (“Objection Notice”). Any item contained in the Title Commitment or any matter shown on the Survey to which Purchaser does not so object shall be deemed a Permitted Exception (as defined below). In the event Purchaser shall timely notify Seller of objections to any item contained in the Title Commitment or to any matter shown on the Survey, Seller may, within five (5) business days after receipt of the Objection Notice (“Response Period”): (a) notify Purchaser in writing of which objections Seller will agree to cure, if any, or (b) not respond, in which event Seller will be deemed to have declined to cure any such objections. Seller shall have no obligation to cure title objections except liens of an ascertainable amount created by Seller, which liens Seller shall cause to be released at the Closing or affirmatively insured over by the Title Company. Seller further agrees to remove any exceptions or encumbrances to title which are created by Seller after the Date of this Agreement without Purchaser’s consent. If Seller elects not to cure all or a portion of Purchaser’s objections or fails to timely respond to the Objection Notice, Purchaser shall have the following options: (i) to accept a conveyance of the Property without reduction of the Purchase Price and subject to the Permitted Exceptions, specifically including any matter in the Title Commitment and/or Survey objected to by Purchaser which Seller is unwilling (or deemed unwilling) to cure, which such objectionable matters shall be deemed waived by Purchaser and become part of the Permitted Exceptions; or (ii) to terminate this Agreement by sending written notice thereof to Seller no later than five (5) days after expiration of the Response Period, and upon delivery of such notice of termination, this Agreement shall terminate and the Earnest Money shall be returned to Purchaser and thereafter neither party hereto shall have any further rights, obligations or liabilities hereunder except for those which survive a termination of this Agreement. If Purchaser fails to timely deliver notice of termination under clause (ii) above, Purchaser will be deemed to have elected to proceed under clause (i) above. Purchaser may terminate this Agreement and receive a refund of the Earnest Money if the Title Company revises the Title Commitment after the expiration of the Title Review Period to add or modify exceptions in a material adverse manner, if such additions or modifications were not created by, through or under Purchaser, are not acceptable to Purchaser and are not removed by the Closing Date. The term “Permitted Exceptions” shall mean: the specific exceptions (exceptions that are not part of the promulgated title insurance form) in the Title Commitment that the Title Company has not agreed to insure over or remove from the Title Commitment as of the end of the Response Period and that Seller is not required to remove as provided above; items shown on the Survey, which have not been removed as of the end of the Response Period; real estate taxes not yet due and payable; acts of Purchaser, and those claiming by, through and under Purchaser; and zoning, building and other governmental and quasi-governmental laws, codes and regulations.

If Seller elects to cure any objections set forth in the Objection Notice, Seller will use commercially reasonable efforts to do so prior to Closing and furnish Purchaser evidence that such objections are cured and removed from title. If Seller is unable to cure any such objections by Closing, Purchaser may either: (x) waive such objections, which shall become Permitted Exceptions, and proceed to Closing without any reduction to the Purchase Price; or (y) terminate this Agreement upon written notice to Seller. Upon delivery of such notice of termination, this Agreement shall terminate and the Earnest Money shall be returned to Purchaser and thereafter neither party hereto shall have any further rights, obligations or liabilities hereunder except for those which survive a termination of this Agreement. If Purchaser fails to timely deliver notice of termination under clause (y) above, Purchaser will be deemed to have elected to proceed to closing under clause (x) above, and such uncured objections will be deemed Permitted Exceptions

4.3 Delivery of Title Policy at Closing. As a condition to Purchaser’s obligation to close, the Escrow Agent shall deliver to Purchaser at Closing an Owner’s Policy of Title Insurance or “marked-up” Owner’s pro forma Owner’s Policy (individually or collectively, as the context may require, the “Title Policy”), issued by the Title Company as of the date and time of the recording of the Deed, in the amount of the Purchase Price, insuring Purchaser as owner of the Property, and subject only to the Permitted Exceptions with extended coverage over all general exceptions to such form of policy. Seller shall execute at Closing an affidavit and such other documents in such form reasonably acceptable to Seller as the Title Company shall require for the issuance of the Title Policy with extended coverage.

Upon failure of any such condition, Purchaser may either (i) extend the Closing Date for a period not to exceed thirty (30) days in order for the Seller to have additional time to perform each undertaking, covenant and agreement hereunder, or (ii) exercise its remedies under Section 16.1. In the event of cancellation of this Agreement pursuant to this Section 9, the Earnest Money Deposit, and any other monies theretofore paid on account, if any, shall be returned to Purchaser and neither party shall have any further liability or obligation to the other hereunder.

SECTION 10: PRORATIONS AND CREDITS AT CLOSING

All prorations provided to be made “as of the Closing Date” shall each be made as of 11:59 P.M. local time on the date immediately preceding the Closing Date. In each proration set forth below, the portion thereof allocable to periods beginning with the Closing Date shall be credited to Purchaser, or charged to Purchaser, as applicable, at Closing or, in the case of allocations made after Closing, upon receipt of such payments or invoice as of the Closing Date. The following items shall, as applicable, be prorated between Purchaser and Seller or credited to Purchaser or Seller:

10.1 Property Taxes and Assessments.

10.1.1 Prorations. All water and sewer fees, charges or rentals and ad valorem or general property taxes with respect to the Real Property shall be prorated and apportioned on a per diem basis as of the Closing Date based on the latest available tax information.

10.1.2 Special Assessments. Certified, confirmed and ratified special assessment liens as of Date of Closing (and not as of the date of this Agreement) shall be paid by Seller or Purchaser shall receive a credit therefor at Closing.

10.2 Utility Expenses and Payments. Seller shall have sole responsibility for all utility charges accrued as of the Closing Date. Seller shall arrange for the utilities to be read as of the Closing Date. Purchaser shall be responsible for making any necessary arrangements for the continuation of all utility services to the Real Property following Closing. Seller and Purchaser shall cooperate with each other and execute all necessary documents as reasonably to accomplish the foregoing.

12

10.3 Other Matters. Seller and Purchaser shall make such other adjustments and apportionments as are expressly set forth in this Agreement.

10.4 Survival. The provisions of this Section 10 shall survive the Closing. In the event final figures have not been reached on any of the adjustments, prorations or costs, as a result of unavailability of information or otherwise, which are to be adjusted at or prior to Closing pursuant to this Section 10, the parties shall close using adjustments and prorations reasonably estimated by Seller and Purchaser, subject to later readjustment when such final figures have been obtained. If more current information is not available, estimates shall be based upon the prior operating history of the Property, as shown on the most recent bills or payments available. The parties hereto agree that they shall seek to determine the amounts of all prorations and adjustments required hereunder on or before the Closing Date, if possible, and to the extent not then obtainable, as soon as practicable thereafter.

SECTION 11: CONVEYANCES AND DELIVERIES

11.1 Deed. At Closing, Seller shall deliver to Purchaser a special warranty deed (the “Deed”) to the Property in recordable form, duly executed by Seller and acknowledged and in substantially the same form as set forth in Exhibit “B” attached hereto, conveying to Purchaser title to the Real Property, subject to the Permitted Exceptions.

11.2 Section 1445 Certificate. At Closing, Seller shall execute and deliver to Purchaser (i) a certificate stating that Seller is not a “foreign person” as defined in Section 1445 of the Internal Revenue Code and the regulations thereunder, (ii) an IRS Form 1099 with respect to this transaction, and (iii) such other documents or instruments as may be required by the Internal Revenue Code (or regulations promulgated pursuant thereto).

11.3 Physical Possession. At Closing, Seller shall deliver to Purchaser possession of the Real Property.

11.4 Other Documents. At Closing, Seller and Purchaser shall deliver to each other any other documents expressly required to be delivered or furnished pursuant to any other provisions of this Agreement or reasonably required to carry out the purpose and intent of this Agreement, including but not limited to: an ALTA Statement and “gap” affidavit, and such other affidavits and related documents that may be required by the Title Company to issue extended coverage, each executed by Seller and in form and substance acceptable to the Title Company.

13

SECTION 12: NOTICES

All notices, consents, approvals and other communications which may be or are required to be given by either Seller or Purchaser under this Agreement shall be properly given only if made in writing (except as expressly provided to the contrary in this Agreement) and sent by (i) U.S. Certified Mail, Return Receipt Requested, (ii) electronic mail with confirmation of receipt, or (iii) a nationally recognized overnight delivery service (such as Federal Express, UPS Next Day Air), with all delivery charges paid by the sender and addressed to the Purchaser or Seller, as applicable, as follows, or at such other address as each may request in writing. Such notices shall be deemed received, (x) if delivered by overnight delivery service, on the date of delivery and (y) if sent by electronic mail, on the date of transmission. Notices to be sent on behalf of Purchaser or Seller may be sent by their respective counsel. The refusal to accept delivery shall constitute acceptance and, in such event, the date of delivery shall be the date on which delivery was refused. Copies of notices directed to a party which are required to be sent to other persons shall be deemed received by such other persons on the date on which the party receives such notice. The addresses for notices are to be as follows:

SECTION 13: CONDEMNATION

13.1 Condemnation. At Closing, Seller shall assign to Purchaser all of Seller’s right, title and interest in and to all awards in condemnation, or damages of any kind, to which Seller is entitled at the time of Closing, by reason of any exercise of the power of eminent domain with respect thereto or for the taking of the Real Property or any part thereof or by reason of any other event affecting the Property which gives rise to a damage claim against a third party after the date hereof. Prior to the Closing Date, if all or any portion of the Real Property is taken, or if access thereto is reduced or restricted, by eminent domain or otherwise (or if such taking, reduction or restriction is pending, threatened or contemplated) (hereinafter a “Condemnation Proceeding”), Seller shall immediately notify Purchaser of such fact. In the event that such notice relates to the taking of a material (as defined below) portion of the Real Property, Purchaser shall have the option, in its sole and absolute discretion, to terminate this Agreement upon written notice to Seller given not later than thirty (30) days after receipt of Seller’s notice; whereupon the Earnest Money Deposit shall be refunded to Purchaser and thereafter neither party shall have any rights, obligations or liabilities hereunder. For the purposes of this Section, and without limiting the generality of the foregoing, a taking shall be deemed material if it restricts access to the Real Property. If Purchaser does not elect to terminate this Agreement as herein provided, Seller shall pay to Purchaser any award received by Seller prior to Closing and Purchaser shall have the right to participate with Seller in any Condemnation Proceeding affecting the Real Property, and Purchaser and Seller shall cooperate with each other in good faith.

SECTION 14: BROKERS

Seller and Purchaser acknowledge that they have not dealt with any broker, finder or agent in connection with this transaction other than CBRE and Newmark (the “Broker”). Seller shall pay the commission, if any, as may be due the Broker pursuant to its written agreement with CBRE. Seller and Purchaser shall indemnify and hold harmless the other against any and all claims, demands, causes of action, losses, costs and expenses (including legal fees and expenses) resulting from a breach of said representation of the indemnifying party. The representations, warranties, undertakings and indemnities of this Section 14 shall survive the Closing hereunder and any termination of this Agreement.

SECTION 15: ASSIGNMENT

Neither party may assign this Agreement without the prior written consent of the other, and any such prohibited assignment shall be void; provided, however, that Purchaser may assign this Agreement without Seller’s consent to an “Affiliate” so long as Purchaser provides Seller prior written notice of such assignment and a fully executed copy of such assignment agreement reasonably acceptable to Seller no later than ten (10) days before the Closing. No assignment permitted under this Agreement shall relieve the assigning party of any liability hereunder, whether arising before or after the date of such assignment. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the respective legal representatives, successors, assigns, heirs, and devisees of the parties. For the purposes of this paragraph, the term “Affiliate” means an entity (a) that directly or indirectly controls, is controlled by or is under common control with the Purchaser and (b) at least a majority of whose economic interest is owned by Purchaser; and the term “control” means the power to direct the management of such entity through voting rights, ownership or contractual obligations.

15

SECTION 16: DEFAULT/REMEDIES

16.1 Seller’s Default/Purchaser’s Remedies. If Seller fails to sell the Property to Purchaser in accordance with this Agreement, or breaches any of its duties, obligations, representations or warranties contained in this Agreement in any material respect, or fails or is unable to deliver any of the documents required to be delivered by Seller hereunder, and provided that such failure or breach is not cured within ten (10) Business Days of the date on which Purchaser notifies Seller of such failure or breach, Purchaser, at its election and as its sole and exclusive legal and equitable remedies, shall be entitled to (i) terminate this Agreement and receive a refund of the Earnest Money Deposit and all Extension Fees, and recoup its Out of Pocket Expenses, (ii) waive the Seller’s default and proceed to close on the terms and conditions set forth in this Agreement without any adjustment to the Purchase Price, or (iii) sue for specific performance of Seller’s obligations hereunder. Purchaser waives any right to pursue any other remedy at law or equity for such default of Seller, including, without limitation, any right to seek, claim or obtain damages, punitive damages or consequential damages, and in no case shall Seller ever be liable to Purchaser under any statutory, common law, equitable or other theory of law, either prior to or following the Closing, for any lost rents, profits, “benefit of the bargain,” business opportunities or any form of consequential damage in connection with any claim, liability, demand or cause of action in any way or manner relating to the Property, the condition of the Property, this Agreement, or any transaction or matter between the parties contemplated hereunder.

16.2 Purchaser’s Default/Seller’s Remedies. If Purchaser wrongfully fails to purchase the Property on the Closing Date in accordance with the terms hereof then Seller, as its sole and exclusive remedy at law or in equity, shall receive the Earnest Money Deposit from Escrow Agent as liquidated damages. Purchaser and Seller acknowledge and agree that damages which would be sustained by Seller in the event of a breach by Purchaser of its obligations under this Agreement are difficult to determine and in such event that the Earnest Money Deposit represents a reasonable estimate of such damages and is not intended as a penalty.

SECTION 17: GENERAL PROVISIONS

17.1 Agreement Binding. This Agreement shall be binding upon each party hereto and such party’s heirs, legal representatives, successors and assigns and shall inure to the benefit of each party hereto and such party’s heirs, legal representatives, successors and assigns.

17.2 Entire Agreement. This Agreement, and all the Exhibits referenced herein and annexed hereto, contain the final, complete and entire agreement of the parties hereto with respect to the matters contained herein, and no prior agreement or understanding pertaining to any of the matters connected with this transaction shall be effective for any purpose. Except as may be otherwise provided herein, the agreements embodied herein may not be amended except by an agreement in writing signed by the parties hereto.

17.3 Governing Law. This Agreement shall be governed by and construed under the laws of the State of Illinois.

17.4 Further Assurances. Seller and Purchaser each agree to execute and deliver to the other such further documents or instruments as may be reasonable and necessary in furtherance of the performance of the terms, covenants and conditions of this Agreement. This covenant shall survive the Closing.

17.5 Interpretation. The titles, captions and paragraph headings are inserted for convenience only and are in no way intended to interpret, define, limit or expand the scope or content of this Agreement or any provision hereof. If any party to this Agreement is made up of more than one person, then all such persons shall be included jointly and severally, even though the defined term for such party is used in the singular in this Agreement. This Agreement shall be construed without regard to any presumption or other rule requiring construction against the party causing this Agreement to be drafted. If any words or phrases in this Agreement shall have been stricken out or otherwise eliminated, whether or not any other words or phrases have been added, this Agreement shall be construed as if the words or phrases so stricken out or otherwise eliminated were never included in this Agreement and no implication or inference shall be drawn from the fact that said words or phrases were so stricken out or otherwise eliminated.

16

17.6 Counterparts; Signatures. This Agreement may be executed in separate counterparts. It shall be fully executed when each party whose signature is required has signed at least one (1) counterpart even though no one (1) counterpart contains the signatures of all of the parties to this Agreement. Any counterpart of this Agreement may be executed and delivered by facsimile or electronic transmission (including, without limitation, e-mail) or by portable document format (pdf) and shall have the same force and effect as an original.

17.7 Non-waiver. No waiver by Seller or Purchaser of any provision hereof shall be deemed to have been made unless expressed in writing and signed by such party. No delay or omission in the exercise of any right or remedy accruing to Seller or Purchaser upon any breach under this Agreement shall impair such right or remedy or be construed as a waiver of any such breach theretofore or thereafter occurring. The waiver by Seller or Purchaser of any breach of any term, covenant or condition herein stated shall not be deemed to be a waiver of any other breach, or of a subsequent breach of the same or any other term, covenant or condition herein contained.

17.8 Severability. This Agreement is intended to be performed in accordance with and only to the extent permitted by applicable law. If any provisions of this Agreement or the application thereof to any person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, but the extent of the invalidity or unenforceability does not destroy the basis of the bargain between the parties as contained herein, the remainder of this Agreement and the application of such provision to other persons or circumstances shall not be affected thereby, but rather shall be enforced to the greatest extent permitted by law.

17.9 Exhibits. The Exhibits referred in and attached to this Agreement are incorporated herein in full by this reference.

17.10 Attorneys’ Fees and Costs. In the event suit or action is instituted to interpret or enforce the terms of this Agreement, or in connection with any arbitration or mediation of any dispute, the prevailing party shall be entitled to recover from the other party such sum as the court, arbitrator or mediator may adjudge reasonable as such party’s costs and attorney’s fees, including such costs and fees as are incurred in any trial, on any appeal, in any bankruptcy proceeding (including the adjudication of issues peculiar to bankruptcy law) and in any petition for review. Each party shall also have the right to recover its reasonable costs and attorney’s fees incurred in collecting any sum or debt owed to it by the other party, with or without litigation, if such sum or debt is not paid within fifteen (15) days following written demand therefor.

17.11 Time of the Essence. Time shall be of the essence in enforcing this Agreement. If the time for performance of any obligation hereunder shall fall on a Saturday, Sunday or holiday (national or in the State of Illinois) such that the transaction contemplated thereby cannot be performed, the time for performance shall be extended to the next succeeding day where performance is possible.
