Buyer shall repair any damages to the Oil and Gas Properties resulting from its inspection. As part of its inspection of the Oil and Gas Properties, Buyer and its authorized representatives shall have the right to conduct soil and water tests and -21- borings, and generally to conduct such tests, examinations, investigations and studies as may be necessary or appropriate in Buyer's sole judgment to make an environmental assessment of the Oil and Gas Properties. Buyer shall keep any data or information acquired through such examination and the results of all analyses of such data and information strictly confidential and shall not disclose the same to any person or agency without the prior written approval of Sellers unless such disclosure is required by law. If Buyer has discovered in its environmental assessment an Environmental Condition, Buyer shall notify Seller of such circumstances as soon as practicable, but in no event less than one (1) day prior to Closing. 7.2. Environmental Condition Attributable to Buyer. Should an identified Environmental Condition be attributable to the acts of Buyer while it was the "Driller" (as that term is defined in that certain Turnkey Drilling Contract by and between CMS and Buyer) of the Oil and Gas Properties, then Sellers shall have no responsibility for the cure or remediation thereof and Buyer will accept the Assets "AS IS" without right of offset or adjustment for any such Environmental Condition. A list of Environmental Conditions for which Buyer is responsible may be attached hereto after the Closing Date as Schedule 7.3. 7.3. Environmental Conditions Attributable to AREC and CMS. If Buyer properly notifies Sellers of an Environmental Condition related to an Oil and Gas Property and attributable to AREC and/or CMS, Buyer may (i) waive the Environmental Condition and close, or (ii) request AREC and CAMI to cure the Environmental Condition. If Buyer asks AREC and CMS to cure an Environmental Condition, and if the aggregate amount of all such Environmental Conditions exceeds Ten Thousand Dollars ($10,000), AREC and CMS have the option (i) to cure -22- the Environmental Condition, or (ii) to exclude the Oil and Gas Property affected by the Environmental Condition from this Agreement. If AREC and CMS elect to cure the Environmental Condition, but the cure has not been completed by Closing, the Oil and Gas Property affected by the Environmental Condition shall not be conveyed to Buyer at Closing, the Purchase Price shall be reduced by the amount allocated to such Oil and Gas Property in Schedule 10.6. If the Environmental Condition is cured by February 14, 2000, within five (5) days after the Environmental Condition is cured, Seller will convey to Buyer the Oil and Gas Property affected by the Environmental Condition and the amount allocated for such Oil and Gas Property on Schedule 10.6 shall be paid to Sellers as part of the Final Settlement Statement. 7.3.1. An Environmental Condition shall be deemed "cured" when: (i) the Buyer and Sellers agree, in writing, that the Environmental Condition has been cured; or (ii) when the Sellers present to Buyer the certification by a licensed environmental engineer that the Environmental Condition has been "cured". Any disagreement between the parties shall be resolved in accordance with the Dispute Resolution provision of Paragraph 14.11 below. 7.4. Environmental Purchase Price Adjustment. Notwithstanding any provision hereof to the contrary, there shall be no reduction in the Purchase Price for uncured Environmental Defects unless, and only to the extent that, the aggregate amount of such uncured Environmental Defects exceeds Ten Thousand Dollars ($10,000), and then only for the amount in excess of such amount. -23- ARTICLE VIII--CONDITIONS TO THE BUYER'S OBLIGATIONS TO CLOSE 8.
