Prior to the expiration of the Inspection Period, Purchaser shall cause an examination to be made of Seller’s title to the Leasehold Estate and Purchaser shall deliver to Seller written notice of any objections to Seller’s title to the Leasehold Estate, other than the Permitted Exceptions, and any objections to the initial As-Built Survey delivered by Seller to Purchaser pursuant to Paragraph 10(m) hereof. In addition, Purchaser may, prior to Closing, re-examine Seller’s title to the Leasehold Estate and any revisions to the As-Built Survey and deliver to Seller any objections, other than the Permitted Exceptions, to Seller’s title to the Leasehold Estate which are recorded subsequent to the effective date of Purchaser’s initial examination of Seller’s title to the Leasehold Estate and/or matters of survey disclosed on any subsequent revision to the As-Built Survey. In the event either of the aforesaid title examinations shows any liens, encumbrances or defects, other than the Permitted Exceptions, or in the event that the As-Built Survey (or any revision thereof) discloses any adverse matters of survey, Purchaser shall give written notice to Seller of any and all such defects and objections, and Seller shall then have three (3) days after receipt of such notice of title and/or survey defects or objections from Purchaser to advise Purchaser in writing which of such title and/or survey defects or objections Seller does not intend to satisfy or cure; provided, however, Seller hereby agrees that Seller shall satisfy or cure at or prior to Closing any such defects or objections consisting of taxes, mortgages, deeds of trust, mechanic’s or materialmen’s liens or other such monetary encumbrances (including the Existing Loan Documents), and any title and/or survey defects or objections created by Seller in violation of this Agreement. In the event Seller fails to give such written advice to Purchaser within such three (3) day period, Seller shall be deemed to have agreed to satisfy or cure all such defects or objections set forth in Purchaser’s notice. Seller shall have until Closing to satisfy or cure all such defects and objections which Seller agreed (or is deemed to have agreed) to satisfy or cure as provided above. If Seller fails or refuses to cure any defects and objections which are required herein to be satisfied or cured by Seller prior to the Closing, then, at the option of Purchaser, (i) Purchaser may terminate this Agreement by written notice to Seller and Escrow Agent, in which event the ▇▇▇▇▇▇▇ Money shall be immediately refunded to Purchaser, and Purchaser and Seller shall have no further rights, obligations or liabilities hereunder, except for the obligations of the parties which are herein expressly stated to survive the termination of this Agreement, (ii) if any such defect or objection is one that Seller agreed (or is deemed to have agreed) to satisfy or cure as provided above, Purchaser may cure such defect or objection, in which event the Purchase Price payable pursuant to Paragraph 3 hereof shall be reduced by an amount equal to the actual cost and expense incurred by Purchaser in connection with the curing of such defect or objection, (iii) Purchaser may accept title to the Leasehold Estate subject to such defects and objections, or (iv) any combination of items (ii) and (iii).

It is hereby agreed that Seller’s damages will be difficult to ascertain and that the ▇▇▇▇▇▇▇ 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 ▇▇▇▇▇▇▇ 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 Paragraph 5 hereof.

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 shall be entitled to an immediate refund of all but Twenty-Five Dollars ($25.00) of the ▇▇▇▇▇▇▇ Money and to pursue against Seller an action for specific performance, or (ii) Purchaser may terminate this Agreement by written notice to Seller, whereupon the ▇▇▇▇▇▇▇ Money shall be immediately returned by Escrow Agent to Purchaser and Seller shall be responsible for, and Purchaser shall be entitled to seek, actual damages from Seller up to a maximum of $500,000.00; provided, however, the foregoing cap or limitation on actual damages shall not be applicable if Seller knowingly and intentionally breaches any covenant to be performed or any representation or warranty made by Seller under this Agreement or knowingly and intentionally does anything to make impossible or defeat the remedy of specific performance.

18. Condemnation. If, after the Effective Date and prior to the Closing, all or any part of the Real Estate 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 Real Estate is contemplated by a body having the power of eminent domain, Seller shall give Purchaser immediate written notice of such threatened or contemplated condemnation or of such taking or sale, and Purchaser may by written notice to Seller given within fifteen (15) 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 ▇▇▇▇▇▇▇ Money shall be returned immediately to Purchaser by Escrow Agent and the rights, duties, obligations, and liabilities of the parties hereunder shall immediately terminate and be of no further force and effect, except for the obligations of the parties which are herein expressly stated to survive the termination of this Agreement.

At such time as all or a part of the Real Estate 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.

Seller has advised Purchaser that a portion of the real property currently constituting the 6405 Property will be taken by eminent domain or condemnation (or sale in lieu thereof) in order to expand the rights-of-way of Georgia Highway 400 and Mount ▇▇▇▇▇▇ Highway, and that following such taking by eminent domain or condemnation (or sale in lieu thereof), the boundaries of the 6405 Property shall be adjusted to the proposed right-of-way lines as shown on that certain Boundary Survey prepared for Seller by HDR/▇.▇. ▇▇▇▇▇▇ Engineers, dated March 27, 2001, last revised May 14, 2002. Purchaser acknowledges and agrees that such condemnation action or proceeding (or sale in lieu thereof) with respect to the 6405 Property as contemplated above shall not give rise to the right of Purchaser to terminate this Agreement, and Purchaser shall have no right to any award that may be made for such taking, notwithstanding that the Real Estate may include easements over and with respect to the portion of the 6405 Property to be so taken.

19. Damage or Destruction.

further force or effect. 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 $250,000.00 and would not give rise to a right by Subtenant to terminate its Sublease), 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(d) 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 (i) that amount necessary to cover any difference between the amount of such proceeds and the estimated cost of repair or replacement, or (ii) the amount of the deductible under Seller’s all–risk 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.
