Indemnification Procedures.

Buyer or a Seller (each, an “Indemnitee”) agrees that promptly after it becomes aware of facts giving rise to a claim by it for indemnification pursuant to this Section 9, including receipt by it of notice of any action, suit, arbitration proceeding, citation, summons or subpoena (civil, criminal, regulatory or otherwise) in law or in equity (a “Proceeding”), by any third party with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, such Indemnitee must assert its claim for indemnification under this Section 9 (each, a “Claim”) by providing a written notice (a “Claim Notice”) to the indemnifying party allegedly required to provide indemnification protection under this Section 9 specifying, in reasonable detail, the nature and basis for such Claim (e.g., the underlying representation, warranty, covenant or agreement alleged to have been breached). Such notice shall include a demand for indemnification under this Agreement. Notwithstanding the foregoing, an Indemnitee’s failure to send or delay in sending a third party Claim Notice will not relieve the indemnifying party from liability hereunder with respect to such Claim except to the extent the indemnifying party is prejudiced by such failure or delay and except as is otherwise provided herein. Except as specifically provided herein, each Indemnitee’s rights and remedies under this Section 9 will survive the Closing.

In the event of the assertion of any third party Claim for which, by the terms hereof, an Indemnitee seeks indemnification from an indemnifying party, the indemnifying party will have the right, at such indemnifying party’s expense, to assume the defense of same including the appointment and selection of counsel on behalf of the Indemnitee so long as such counsel is reasonably acceptable to the Indemnitee. If the indemnifying party elects to assume the defense of any such third party Claim, it shall within twenty (20) business days of its receipt of the Claim Notice notify the Indemnitee in writing of its intent to do so. Any such contest may be conducted in the

If requested by the indemnifying party, the Indemnitee agrees to cooperate with the indemnifying party and its counsel in contesting any third party Claim that the indemnifying party elects to contest or, if appropriate, in making any counterclaim against the person asserting the third party Claim, or any cross-complaint against any person, and the indemnifying party will reimburse the Indemnitee for reasonable expenses incurred by it in so cooperating. At no cost or expense to the Indemnitee, the indemnifying party shall reasonably cooperate with the Indemnitee and its counsel in contesting any third party Claim.

Notwithstanding anything to the contrary in this Agreement, the indemnifying party will not be permitted to settle, compromise, take any corrective or remedial action or enter into an agreed judgment or consent decree, in each case, that subjects the Indemnitee to any injunctive or other non-monetary relief or any criminal liability, requires an admission of guilt or wrongdoing on the part of the Indemnitee or imposes any continuing obligation on or requires any payment from the Indemnitee without the Indemnitee’s prior written consent.

Calculation of Damages. In calculating amounts payable to an Indemnitee for a claim for indemnification hereunder, the amount of any indemnified Damages shall be determined without duplication of any other Damages for which an indemnification claim has been made or could be made under any other representation, warranty, covenant or agreement and shall be computed net of (i) payments actually recovered under any insurance policy with respect to such Damages or (ii) any prior or subsequent actual recovery from any person other than the applicable indemnifying party with respect to such Damages.

Waiver of Certain Damages. Notwithstanding any other provision of this Agreement, in no event shall any Party be liable pursuant to this Section 9 for punitive, special, indirect, consequential, remote, speculative or lost profits Damages of any kind or nature, including any Damages based on diminution in value or any other damages based on a multiple of earnings or other multiple, regardless of the form of action through which such damages are sought, except (i) for any such damages recovered by any third party against an Indemnitee in respect of which such Indemnitee would otherwise be entitled to indemnification pursuant to the terms hereof and (ii) in the case of consequential damages, (x) to the extent an Indemnitee is required to pay consequential damages to an unrelated third party and (y) to the extent of consequential damages to an Indemnitee arising from fraud or willful misconduct.

Sole Remedy. After the Closing, no Party shall have liability under this Agreement or the transactions contemplated hereby except as is provided in this Section 9 (other than claims or causes of action arising from fraud, and other than claims for specific performance).
