Without limiting any of Post-Closing Seller's above indemnification obligations, Post-Closing Seller further acknowledges and agrees that its obligation to indemnify the Buyer Indemnified Parties includes, without limitation with respect to any breach by any of the Constellation Parties of its representations and warranties under Section 6(b): (i) any and all Remedial Costs associated with any Tank, Hazardous Material, Hazardous Condition or any Release; (ii) to the maximum extent allowed by law, all fines and/or penalties that may be imposed in connection with any Tank or the existence of any Hazardous Material on, at, under, near, in or about the Property; (iii) the defense of any claim made by any individual or entity (including any government, governmental agency or entity) concerning any of the foregoing, 14 which defense shall be conducted by counsel and with the assistance of environmental advisors and consultants, in all cases subject to the prior written approval of Buyer; and (iv) reasonable attorneys' fees and costs and environmental advisors' and consultants' fees incurred by any of the Buyer Indemnified Parties with respect to enforcing its rights under this indemnification provision. This Section 6 shall survive the Closing for a period of thirty (30) months. 7. TITLE. At the Closing, Seller agrees that the Company shall have good and marketable fee simple title to the Property, free and clear of all liens, claims and encumbrances except for the Permitted Exceptions. From and after the date of this Agreement, Company shall not take any action, or fail to take any action, that would cause title to the Property to be subject to any title exceptions or objections, other than the Permitted Exceptions. (a) On or before forty-five (45) days after the Contract Date, Buyer shall furnish Seller with a preliminary title report covering the Property (the "Title Report") and a written notice specifying those title exceptions which are not acceptable to Buyer, which objection may include matters shown on any updated or re-certified survey which Buyer may obtain (the "Disapproved Exceptions"). Buyer's failure to designate as one of the Disapproved Exceptions a title exception shown on the Title Report shall constitute Buyer's approval of such title exception (all title exceptions not designated by Buyer as Disapproved Exceptions are in this Agreement called "Permitted Exceptions" and, if Buyer has elected to purchase the Shares with the Property subject to the Assumed Indebtedness, the Assumed Indebtedness shall be a Permitted Exception). The Seller shall cause the Company to use its best efforts to cause the removal of all Disapproved Exceptions on or before ten (10) days after Buyer's notice to Seller of such Disapproved Exceptions, except that liens of an ascertainable amount and other items which can be removed by the payment of money shall be paid and discharged by Seller or the Company at or before Closing. Within such ten (10) day period, Seller shall notify Buyer of all Disapproved Exceptions that Seller, after using its best efforts, is unable to remove. Seller's failure to give Buyer notice of Seller's inability to remove any Disapproved Exceptions shall constitute Seller's covenant that such Disapproved Exceptions shall be removed at or prior to the Closing. Buyer shall have the rights set forth in 7(c) if any Disapproved Exceptions cannot be removed by Seller(s) at or prior to the Closing. (b) It shall be a Condition under this Agreement that the marked-up Title Reports delivered on the Closing Date shall be in the form described in this Section 6 and have all standard and general printed exceptions deleted so as to afford full "extended form coverage," and shall further include an owner's comprehensive endorsement, an endorsement certifying that the bills for the real estate taxes pertaining to the Property do not include taxes pertaining to any other real estate; an access endorsement; a contiguity endorsement, if applicable; a subdivision or plat act endorsement; a survey endorsement; a non-imputation endorsement; a Fairway endorsement; and a creditors' rights endorsement. (c) If Seller or the Company is unable to correct or remove any Disapproved Exceptions in accordance with the requirements of this Section 7, Buyer shall have the sole option of either (i) completing the Closing subject to such Disapproved Exceptions without any abatement of the Purchaser Price, except that liens of an ascertainable amount and other items 15 which can be removed by payment of money shall be paid and discharged by Seller or Company prior to Closing or (ii) being immediately paid Buyer's Reasonable Costs (as defined below) and, in the latter event, the parties shall be released from all liability or obligation to the other and this Agreement shall then and thereafter be null and void. "Buyer's Reasonable Costs" shall mean all out-of-pocket costs and expenses incurred by Buyer in connection with this Agreement and the Property, including, but not limited to, legal fees, title company charges, engineering fees, environmental consultant's fees, architects' and surveyors' fees and other similar charges. 8.

The waiver of any particular Buyer's Condition Precedent shall not constitute the waiver of any other. (e) CONSTRUCTION.

The headings of various Sections in this Agreement are for convenience only, and are not to be utilized in construing the content or meaning of the substantive provisions hereof. (f) GOVERNING LAW.

(i) CONTROL OF DEFENSE COUNSEL. Each indemnified party shall give reasonably prompt notice to each indemnifying party of any action or proceeding commenced against the indemnified party in respect of which indemnity may be sought hereunder, but failure so to notify an indemnifying party (i) shall not relieve it from any liability which it may have 34 under any indemnity provided herein unless and to the extent it did not otherwise learn of such action and the lack of notice by the indemnified party results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) shall not, in any event, relieve the indemnifying party from any obligations to any indemnified party hereunder other than its indemnification obligation if the indemnifying party so elects within a reasonable time after receipt of such notice, the indemnifying party may assume the defense of such action or proceeding at such indemnifying party's own expense with counsel chosen by the indemnifying party; provided, however, that, if such indemnified party or parties reasonably determine that a conflict of interest exists where it is advisable for such indemnified party or parties to be represented by separate counsel or that, upon advice of counsel, there may be legal defenses available to them which are different from or in addition to those available to the indemnifying party, then the indemnifying party shall not be entitled to one separate counsel at the indemnifying party's expense. If an indemnifying party is not so entitled to assume the defense of such action or does not assume such defense, after having received the notice referred to in the first sentence of this Section, the indemnifying party or parties will pay the reasonable fees and expenses of counsel for the indemnified party or parties. In such event however, no indemnifying party will be liable for any settlement effected without the written consent of such indemnifying party. If an indemnifying party is entitled to assume, and assumes, the defense of such action or proceeding in accordance with this Section, such indemnifying party shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action or proceeding.
