Section 8.6 Procedure with Respect to Third Party Claims. Subject to Section 7.4 and Section 8.6(e), which shall govern Claims with respect to Taxes, the following provisions shall apply.

(a) If an Indemnified Party becomes subject to a pending or threatened Claim of a third party and believes it has a Claim against an Indemnifying Party as a result, then such Indemnified Party shall notify the Indemnifying Party in writing of the basis for such Claim setting forth the nature of the Claim in reasonable detail, as soon as practical following the time at which the Indemnified Party discovered, or reasonably should have discovered, such Claim. The failure of such Indemnified Party to so notify the Indemnifying Party shall not relieve the Indemnifying Party of liability hereunder except to the extent that the defense of such Claim is prejudiced by the failure to give such notice.

(b) If any proceeding is brought by a third party against such Indemnified Party and such Indemnified Party gives notice to the Indemnifying Party pursuant to this Section 8.6, the Indemnifying Party shall be entitled to participate in such proceeding and, to the extent that it wishes, to assume the defense of such proceeding (with counsel reasonably satisfactory to the Indemnified Party), if the Indemnifying Party provides written notice to such Indemnified Party within thirty (30) days that the Indemnifying Party intends to undertake such defense and provided that (1) the potential liability of such Claim does not exceed the maximum liability of the Indemnifying Party hereunder and (2) doing so would not create a conflict of interest between the Indemnified Party and the Indemnifying Party. The Indemnified Party shall, in its sole discretion, have the right to employ separate counsel in any such action and to participate in the defense thereof, and the reasonable fees and expenses of such counsel shall be paid by such Indemnified Party. The Indemnifying Party may not settle any Claim without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld.

(c) If notice is given to the Indemnifying Party by the Indemnified Party of the commencement of any third party legal proceeding and the Indemnifying Party does not, within thirty (30) days after receiving such notice, give notice to the Indemnified Party of its election to assume the defense of such legal proceeding (or the Indemnifying Party is not permitted to assume the defense under Section 8.6(b)), then such Indemnified Party shall (upon notice to the Indemnifying Party) have the right to undertake the defense or compromise of such Claim; provided, that (i) the Indemnified Party cannot settle any Claim without the prior written consent

of the Indemnifying Party, which shall not be unreasonably withheld, and (ii) the Indemnifying Party shall reimburse the Indemnified Party for the costs of defending against such third party Claim (including reasonable attorneys’ fees and expenses) to the extent it is determined that such Indemnifying Party is liable under this Agreement with respect to such third party Claim. The Indemnifying Party may elect to participate in such legal proceedings, negotiations or defense at any time at its own expense.

(d) Notwithstanding anything else contained in this Agreement, with respect to a Claim with respect to Taxes, (I) (i) Seller shall only have the right to control a Claim with respect to Taxes if (A) it relates to a taxable year or other taxable period that ends on or prior to the Closing Date and (B) such Taxes are imposed on Seller, and (ii) Seller shall not consent to any settlement or compromise of any Claim with respect to Taxes that could reasonably be expected to adversely impact Buyer or the Acquired Assets without written consent of Buyer, which consent shall not be unreasonably withheld or delayed, and (II) Buyer shall have the right to control all other Claims for indemnification regarding Taxes. Seller, at its own expense, shall be entitled to participate in any Claim with respect to Taxes for any taxable period beginning on or before and ending after the Closing Date, or for any taxable period ending on or before the Closing Date if Seller did not choose to control the contest of such claim with respect to Taxes pursuant to this Agreement, and Buyer shall not settle any such Claim that could reasonably be expected to adversely impact Seller without written consent of Seller, which consent shall not be unreasonably withheld or delayed.

(e) Sections 8.6(a) through (e) apply only to indemnification relating to third party Claims. A Party may assert an indemnity Claim not related to a third party Claim by providing notice to the other Party within the applicable time periods set forth in Section 8.1(b) and Section 8.1(c), respectively.

Section 8.7 “As Is” Sale. IT IS THE EXPLICIT UNDERSTANDING OF EACH PARTY THAT NOTHING IN THIS AGREEMENT SHALL IMPLY OR BE CONSTRUED TO MEAN THAT SELLER HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS, IMPLIED, AT COMMON LAW, STATUTORY OR OTHERWISE, EXCEPT FOR THE REPRESENTATIONS OR WARRANTIES EXPRESSLY SET FORTH IN THIS AGREEMENT, AND IT IS FURTHER UNDERSTOOD BY THE PARTIES THAT, EXCEPT AS SET FORTH IN THIS AGREEMENT, BUYER IS PURCHASING THE ACQUIRED ASSETS AND ASSUMING THE ASSUMED LIABILITIES “AS IS,” “WHERE IS” AND “WITH ALL FAULTS.” WITHOUT LIMITING THE GENERALITY OF THE IMMEDIATELY PRECEDING SENTENCE, SELLER HEREBY EXPRESSLY DISCLAIMS AND NEGATES ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AT COMMON LAW, STATUTORY, OR OTHERWISE, RELATING TO THE CONDITION, VALUE OR QUALITY OF THE ACQUIRED ASSETS (INCLUDING ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, AND SELLER MAKES NO REPRESENTATION OR WARRANTY TO BUYER WITH RESPECT TO ANY FINANCIAL PROJECTION OR FORECAST RELATING TO

THE ACQUIRED ASSETS OR THE PROSPECTS, RISKS OR OTHER INCIDENTS OF OWNERSHIP THEREOF. EXCEPT AS SET FORTH IN THIS AGREEMENT, SELLER MAKES NO, AND SPECIFICALLY NEGATES AND DISCLAIMS ANY, WARRANTIES OR REPRESENTATIONS OF ANY KIND OR CHARACTER WHATSOEVER, EXPRESS OR IMPLIED, ORAL OR WRITTEN, AS TO, CONCERNING OR WITH RESPECT TO THE SITE OR THE FACILITY. THE FOREGOING IS NOT INTENDED TO LIMIT FRAUD CLAIMS.

Section 8.8 Release. If the Closing occurs, effective as of the Closing, Buyer, on behalf of itself and its respective Affiliates, Representatives, direct and indirect parent companies, managers, officers and directors, and each of their respective successors and assigns (each a “Releasor”), except as set forth in this Agreement or any Ancillary Agreement, hereby releases, waives, acquits and forever discharges, to the fullest extent permitted by Law, Seller, and its respective past, present and future Affiliates, Representatives, direct and indirect parent companies, managers, officers and directors of, from and against any and all actions, causes of action, claims, demands, damages, judgments, Liabilities, debts, dues and suits of every kind, nature and description whatsoever, arising directly or indirectly out of the Assumed Liabilities, the Acquired Assets and the Business (as presently or formerly conducted), which such Releasor ever had, now has or may have on or by reason of any matter, cause or thing whatsoever on or prior to the Closing Date under any applicable Environmental Law, including the Comprehensive Environmental Response, Compensation and Liability Act or similar international, foreign, federal, regional or state Law, whether or not in existence on the Execution Date.
