In the event that Purchaser shall fail to consummate the purchase of the Project on or before the Closing Date for any reason other than termination hereof pursuant to a right granted to Purchaser to do so, failure of any condition set forth herein, or breach by Seller of its representations, warranties, covenants or agreements hereunder, then, as its sole and exclusive remedy hereunder, Seller may terminate this Agreement and receive the Earnest Money from the Title Company, whereupon neither party shall have any further obligations hereunder except as set forth herein. Seller agrees to accept such sum as its total liquidated damages and relief and as its sole remedy, at law or in equity, for Purchaser's default hereunder, the parties having agreed that in the event of a default hereunder by Purchaser, the actual harm to Seller will be extremely difficult and impracticable to determine, and Seller and Purchaser agree that said liquidated damages are not intended as a penalty. 15.2 Purchaser's Remedies on Seller's Default. In the event Seller shall fail or refuse to fully and timely perform any of its obligations hereunder and such failure continues for five (5) days after written notice thereof, or shall fail or refuse to consummate the sale of the Project for any reason not set forth in this Agreement, except where caused solely by Purchaser's default, then as its sole and exclusive remedies hereunder, Purchaser may: (i) terminate this Agreement and recover (a) from the Title Company, the Earnest Money, and (b) from Seller, Purchaser's actual out-of- pocket expenses incurred in connection with the transaction herein contemplated, up to a maximum of $35,000.00 (including such amounts as contemplated by Sections 6.3 and 7.2 hereof), and thereafter neither party shall have any further obligations hereunder except as set forth herein, or (ii) enforce specific performance of this Agreement (and should Purchaser be successful in enforcing specific performance, Seller shall be responsible for all of Purchaser's court costs and attorneys' fees incurred in connection therewith). In the event Seller fails or refuses to perform any covenant or agreement herein undertaken or fails or refuses to furnish any item or thing or permit any inspection, then Purchaser may, at its election, either waive such compliance or performance by Seller and proceed to Closing, or extend the Closing Date for such period of time (not to exceed thirty (30) days) deemed appropriate by Purchaser in which event the substituted Closing Date shall thereafter be and constitute the Closing Date hereunder. ARTICLE 16 INDEMNITY Intentionally Deleted ARTICLE 17 SPECIAL PROVISIONS Notwithstanding anything to the contrary herein, satisfaction of all of the provisions of this Article 17 shall be a further express condition precedent to the obligations of Purchaser to close the -23- 28 transaction contemplated hereby. 17.1 Financing. Purchaser shall seek to obtain financing (the "Financing") for the acquisition of the Project from a lender ("Purchaser's Lender") on terms and conditions satisfactory to Purchaser in its sole discretion on or before the expiration of the Review Period. If Purchaser is unable to obtain such financing, then Purchaser shall have the absolute and unfettered right, at any time prior to expiration of the Review Period, to terminate this Agreement by sending written notice of such termination to Seller and the Title Company, whereupon the Title Company shall return the Earnest Money to Purchaser and the parties hereto shall have no further obligations under this Agreement, except as may otherwise be provided herein. Seller agrees to cooperate with Purchaser in seeking to cause I/O and Tenants to execute, such estoppel certificates, subordination, nondisturbance and attornment agreements, and other instruments as Purchaser's Lender may reasonably require in connection with such financing, and Seller further agrees to cooperate with Purchaser's Lender and to allow such lender and its contractors, appraisers and representatives reasonable access to the Project to inspect same and to perform such other due diligence in connection with the loan as they may reasonably deem necessary; subject, however, to the provisions set forth in Article 18 hereof. In addition, Seller agrees that Purchaser may share all studies, tests, reports, financial data and other information regarding the Project provided by Seller to Purchaser with Purchaser's Lender and prospective lenders. 17.2 Master Lease. At Closing, I/O and Purchaser shall enter into a Master Lease to be negotiated by Purchaser and I/O during the Review Period (as such term is defined below). ARTICLE 18 REVIEW PERIOD For the purposes of this Agreement, the term "Review Period" shall mean the period of time commencing on the Effective Date and expiring on the sixtieth (60th) day following the Effective Date. During the Review Period, Purchaser, at Purchaser's expense, may review all of the documents, items, information and materials identified in Section 8.1 hereof, and may conduct soil tests, structural tests, and such other engineering and economic feasibility tests and studies and such other inspections or investigations with respect to the Project, as Purchaser may desire or deem appropriate. Seller agrees to reasonably cooperate with and reasonably assist Purchaser in the physical inspection of the Project and the inspection of such documents, items, information and materials, provided that such inspection shall be conducted during normal business hours or at such other time as is reasonable and necessary to conduct the inspection, and shall not unreasonably interfere with the normal business of Seller, I/O or Tenants. If, within the Review Period, Purchaser shall, for any reason, in Purchaser's sole and absolute discretion, be dissatisfied with any aspect of the Project, then Purchaser shall have the absolute and unfettered right to terminate this Agreement by sending written notice of such termination to Seller at any time prior to the expiration of the Review Period. In the event that Purchaser terminates this Agreement, as provided above, the Title Company shall return the Earnest Money to Purchaser and the parties hereto shall have no further obligations under this Agreement, except as may otherwise be provided herein. Purchaser agrees to indemnify, defend and hold harmless Seller from, against and with respect to any and all losses, -24- 29 costs, expenses, claims, demands and causes of action (collectively, "Losses") caused by Purchaser's or any of its agents', employees' or representatives' activities at the Property pursuant to this Article 18; provided, however, the foregoing indemnity shall not extend to any Losses attributable to the acts, omissions or negligence of Seller or any of its agents, employees or representatives, or to any defects or dangerous conditions existing at the Project. Purchaser shall have the right to extend the Review Period for up to forty-five (45) additional days by delivering written notice of such extension to Seller not less than three (3) days prior to the expiration of the original Review Period if Purchaser has identified a proposed lender and Purchaser reasonably believes that it requires such additional forty-five (45) day period in order to finalize the financing described in Article 17 hereof. ARTICLE 19 MISCELLANEOUS 19.1 Disclosures. (1) Each of the parties to this Agreement shall keep confidential and shall not without the consent of the other disclose the terms of, or provide a copy of, this Agreement to any Person prior to the Closing Date, except that each party may, to the extent reasonably necessary in connection with the exercise of such party's rights and obligations hereunder or in connection with any litigation arising in connection herewith, disclose material terms hereof to the party's accountants, brokers, engineers, attorneys, lenders and other similar professionals involved in the transaction contemplated hereby.

The validity of the remaining provisions of this Agreement shall not be affected by any such modification or severance, except that if any severance materially alters the intentions of the parties hereto as expressed herein (a modification being permitted only if there is no material alteration), then the parties hereto shall use commercially reasonable efforts to agree to appropriate equitable amendments to this Agreement in light of such severance. 19.5 Survival.
