Buyer’s Initials

5. Conditions of Buyer’s Obligations. The Closing and Buyer’s obligations under this Agreement to purchase the Property shall be subject to the satisfaction, prior to the times prescribed herein, of the following conditions in Buyer’s sole and absolute discretion, with Buyer to retain the right to waive, in writing, in whole or in part, any of the following conditions (collectively, the “Contingencies”) at or prior to the time prescribed herein for approval or disapproval by Buyer:

5.1 Title Report. Within five (5) days after the Execution Date, Seller shall deliver to Buyer a preliminary title report prepared by First American Title Insurance Company (“Title Company”) with respect to the Property (the “Title Report”), together with complete

copies of all exceptions set forth therein. Buyer shall have until 5:00 p.m. (Pacific Time) on the date which is twenty five (25) days after the Execution Date (or the next business day if such date falls on a weekend or holiday) (the “Due Diligence Period”) to notify Seller and the Escrow Agent, in writing, of Buyer’s disapproval of any exceptions or items shown thereon and to obtain the commitment of the Title Company to issue the Title Policy (as defined in Section 5.5 below), including such endorsements as Buyer may reasonably request. If Buyer does not give Seller written notice of approval of any of the foregoing items within the prescribed time, the Title Report and the supporting documents shall be deemed disapproved. Buyer may at any time during the Due Diligence Period object to any title matters affecting the Property by providing written notice of such objections to Seller. Within five (5) days of receipt of Buyer’s notice of disapproval of any of the foregoing items, Seller shall notify Buyer whether Seller is willing to remove any such item which Buyer has disapproved (“Seller’s Cure Notice”). If Seller does not give Buyer written notice within the prescribed period of time, Seller shall be deemed to have elected not to remove any such item which Buyer has disapproved. If there are exceptions which Buyer has disapproved and which Seller is not willing to remove at Seller’s expense, Buyer shall have until the end of the later of (A) the expiration of the Due Diligence Period, or (B) the fifth (5^th) day following Buyer’s receipt of Seller’s Cure Notice (or the expiration of the five (5) day period within which Seller is to deliver a Seller’s Cure Notice if Seller fails to deliver a Seller’s Cure Notice) to notify Seller in writing of Buyer’s election to either (a) waive its disapproval and approve such exceptions, or (b) terminate this Agreement and receive a refund of the Deposit, with Buyer’s failure to respond in writing within such period to be deemed Buyer’s election to terminate this Agreement. If Buyer elects to waive its disapproval and approve any such exceptions, such exceptions then shall be deemed to become Permitted Exceptions at the Closing. Buyer agrees that the parties’ failure to have resolved the scope of Permitted Exceptions pursuant to this Section 5.1 prior to the expiration of the Due Diligence Period shall not effect any extension of the Due Diligence Period or the Closing Date absent both parties’ written agreement. If Seller provides Buyer with a Seller’s Cure Notice stating that Seller is willing to remove, cure or ameliorate certain items disapproved by Buyer, Seller shall cause all such items to be removed, cured or ameliorated to the extent provided in Seller’s Cure Notice on or before the Closing Date. Seller’s failure to timely remove, cure or ameliorate all such items as provided in Seller’s Cure Notice shall not be a default hereunder so long as Seller has undertaken commercially reasonable efforts in good faith. As used herein, “Permitted Exceptions” shall mean those exceptions to the Title Policy approved by Buyer.

5.2 Due Diligence Period.

5.2.1 At all times during the “Due Diligence Period”, Buyer, its authorized agents, employees, consultants and representatives (“Buyer’s Agents”) shall have the right to enter the Property at reasonable times and at reasonable intervals to conduct and carry out any and all non invasive inspections, tests, and studies as Buyer deems appropriate or Buyer’s lender requires. Buyer shall not have the right to do any invasive testing of the Property or the Improvements located thereon without the prior written consent of Seller, which consent may be withheld in Seller’s reasonable discretion. Buyer shall provide notice to Seller of its intent to enter the Property and provide Seller the right to accompany Buyer on such entry. Buyer shall indemnify and hold Seller harmless from all claims and demands arising from Buyer’s entry upon the Property.

Buyer’s failure to deliver either an Approval Notice or a Termination Notice within the Due Diligence Period shall conclusively be considered Buyer’s disapproval of all the conditions and documents in Section 5.1 and this Section 5.2 and Buyer’s election to terminate this Agreement, in which case Buyer shall immediately receive a refund of the Initial Deposit.

5.2.2 During the Due Diligence Period, Buyer and Buyer’s Agents shall be granted a right of entry on the Property (i) to perform such non invasive engineering, environmental and geological reviews as Buyer shall deem appropriate, (ii) examine all structural and mechanical systems within the Improvements, (iii) examine the books and records of Seller relating to the management, ownership, use and operation of the Property, and (iv) conduct such other non invasive physical inspections and make such other reports as Buyer shall deem appropriate for any purpose related to Buyer’s proposed use of the Property.

(d) Buyer shall keep the Property free and clear of all liens arising out of the activities of Buyer or Buyer’s Agents conducted upon the Property;

(e) Buyer shall indemnify and hold Seller harmless from any lien, loss, claim, liability, or expense, including attorneys’ fees and costs, arising out of or in connection with the activities of Buyer or Buyer’s Agents on or about the Property;

insured upon such insurance. Buyer shall provide proof of such insurance reasonably acceptable to Seller prior to, and as a condition of, any such entry; and

(g) Prior to performing any invasive testing (i.e. testing involving drilling, boring or other similar physically intrusive investigation), Buyer shall obtain Seller’s written approval, which approval may be withheld in Seller’s reasonable discretion, with respect to the scope of work intended to be performed and shall provide Seller an opportunity to confer, either directly or through Seller’s consultants, with Buyer’s environmental consultants in order to determine whether to permit any sampling or testing of surface or subsurface soils, surface water or ground water or to refine the scope of the work to be performed.

Seller shall be entitled to receive copies of all tests and test results generated by Buyer with respect to the Property, including draft versions of the same, as and when received by Buyer.

Upon such termination, the Deposit shall be paid to Seller to the extent it has become nonrefundable in accordance with this Agreement, unless the failure of a condition is caused solely by Seller’s breach of a representation, warranty covenant or obligation of Seller arising under this Agreement, subject to Section 10.2 below (a “Seller’s Breach), in which event the Deposit shall be refunded to Buyer.
