If Buyer shall not so elect, Buyer may terminate this Agreement by notice in writing to Seller, whereupon the Deposit shall be immediately refunded to Buyer, and this Agreement shall be null and void, and the parties hereto shall be relieved of all further obligations and liability under this Agreement. 7.2 Survey.

Promptly after receipt by Buyer of written notice of the commencement of any suit, audit, demand, judgment, action, investigation or proceeding (a "Third Party Action") or promptly after Buyer incurs a Loss or has knowledge of the existence of a Loss, Buyer will, if a claim with respect thereto is to be made against Seller due to Seller's obligation to provide indemnification hereunder, give Seller written notice of such Loss or the commencement of any Third Party Action; provided, however, that the failure to provide such notice within a reasonable period of time shall not relieve Seller of any of its obligations hereunder, unless Seller is materially prejudiced by such delay. Promptly after receiving such notice, Seller will, upon notice to Buyer, have the right to assume and control the defense and settlement of any such Third Party Action at its own cost and expense; provided, however, that it shall be a condition precedent to the exercise of such right by Seller that Seller shall agree in writing that the Loss, or Third Party Action, as the case may be, is properly within the scope of the indemnification obligation and that as between the parties, Seller shall be responsible to satisfy and discharge such Third Party Action. Seller shall not enter into any resolution or other compromise of a Third Party Action without obtaining the complete release of Buyer for any liability to all claimants under or pursuant to such Third Party Action. Buyer shall have the right to participate in any such defense, contest or other protective action at its own cost and expense. Notwithstanding the foregoing, Buyer shall have the right to assume and control the defense and settlement of a Third Party Action (a) if such action includes claims for equitable relief which, if determined adversely to Buyer, could reasonably be expected to interfere with its intended business operations or damage its business reputation or (b) if Seller fails to do so in a 23 timely manner. In any circumstances in which Buyer undertakes to control the Third Party Action as provided in this paragraph, it shall (i) not enter into any resolution or other compromise involving monetary damages without obtaining the prior written consent of Seller provided that such written consent may not be withheld if it would interfere with Buyer's business operation and (ii) keep Seller informed on an ongoing basis of the status of such Third Party Action and shall deliver to Seller, copies of all documents related to the Third Party Action reasonably requested by Seller. Buyer shall act to assure that all attorneys' fees and expenses incurred in connection therewith are reasonable. 21. EXCULPATION. No recourse shall be had for any obligation of Brandywine Realty Trust under this Agreement or under any document executed in connection herewith or pursuant hereto, or for any claim based thereon or otherwise in respect thereof, against any past, present or future trustee, shareholder, officer or employee of Brandywine Realty Trust, whether by virtue of any statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being expressly waived and released by the Seller and all parties claiming by, through or under Seller. 22. AS-IS. Buyer acknowledges and agrees that except as herein elsewhere specifically provided, Seller has not made, does not make and specifically negates and disclaims any representations, warranties (other than the special warranty of title as set out in the deed), promises, covenants, agreements or guaranties of any kind or character whatsoever, whether express or implied, statutory, oral or written, past, present or future, of, as to, concerning or with respect to (A) the value, nature, quality or condition of the Property, including, without limitation, the water, soil, and geology, (B) the suitability of the Property for any and all activities and uses which Buyer or any tenant may conduct thereon, (C) the compliance of or by the Property or its operation with any laws, rules, ordinances or regulations of any applicable governmental authority or body, (D) the habitability, merchantability, marketability, profitability or fitness for a particular purpose of the Property, (E) the manner or quality of the construction or materials, if any, incorporated into the Property, (F) the manner, quality, state of repair or lack of repair of the Property, (G) compliance with any environmental requirements, including the existence in or on the Property of hazardous materials or (H) any other matter with respect to the Property. Additionally, no person acting on behalf of Seller is authorized to make, and by execution hereof, Buyer acknowledges that, except as herein elsewhere specifically provided, no person has made any representation, agreement, statement, warranty, guaranty or promise regarding the Property or the transaction contemplated herein; and no such representation, warranty, agreement, guaranty, statement or promise, if any, made by any person acting on behalf of Seller shall be valid or binding upon Seller unless expressly set forth herein. Buyer further acknowledges and agrees that, except with respect to information developed by Seller, its 24 principals or affiliates, any information provided or to be provided with respect to the Property was obtained from a variety of sources, that Seller has not made any independent investigation or verification of such information and makes no representations as to the accuracy, truthfulness or completeness of such information, and the Buyer may not be entitled to rely on any such information. The foregoing notwithstanding, Seller has no knowledge that any such information is inaccurate or misleading. Buyer further acknowledges and agrees that to the maximum extent permitted by law, and except as herein elsewhere specifically provided, the sale of the Property as provided for herein is made on an "as is" condition and basis with all faults. It is understood and agreed that the purchase price has been adjusted by prior negotiation to reflect that the Property is sold by Seller and purchased by Buyer subject to the foregoing. 23. Other Transactions. The obligations of the parties to consummate Closing hereunder shall be expressly conditioned upon (i) Seller and Brandywine Operating Partnership, L.P., a Delaware limited partnership ("BOP") executing and delivering a mutually satisfactory operating agreement regarding the governance of Buyer, (ii) closing by Brandywine Realty Trust, or BOP, as buyer, and Seller, as seller, under that certain Agreement of Sale dated of even date herewith regarding the purchase and sale of 100 Commerce Drive, Newark, New Castle County, Delaware, (iii) Seller and BOP executing and delivering a mutually satisfactory operating agreement regarding the governance of Christiana Center Operating Company I LLC and (iv) the execution and delivery by Seller, as seller, and the said Christiana Center Operating Company I LLC as buyer of a mutually satisfactory Agreement of Sale regarding the purchase and sale of that certain property known as and numbered 400 Commerce Drive, Newark, New Castle County, Delaware, each and all upon terms and conditions acceptable to the parties, failing which neither party hereto shall have any obligation to consummate Closing hereunder. If either party shall elect to terminate this Agreement in such instance, then in that event, the Deposit shall be promptly refunded to the Buyer and thereupon neither party shall have any further obligation to the other hereunder.
