(a) Each Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim by it for indemnification pursuant to Section 8.02, such Indemnified Party will assert its claim for indemnification under Section 8.02 (each, a “Claim”) by providing a written notice (a “Claim Notice”) within the applicable Survival Period to the applicable indemnifying party (the “Indemnifying Party”) specifying, in reasonable detail, to the extent known by such Indemnified Party, the nature and basis for such Claim (e.g., the underlying representation, warranty or covenant alleged to have been breached and the condition or conduct allegedly resulting in such breach). Notwithstanding the foregoing, an Indemnified Party’s delay in sending a Claim Notice will not relieve the Indemnifying Party from Liability hereunder with respect to such Claim except to the extent (and limited solely to the extent) of any material prejudice to the Indemnifying Party by such failure or delay, provided that such Claim Notice is provided within the applicable Survival Period.

(b) In the event that any Proceeding is instituted or any Claim is asserted by any Third Party in respect of which indemnification may be sought under Section 8.02 hereof and in respect of which the Indemnifying Party has agreed in writing to indemnify the Indemnified Party for all of such Indemnified Party’s Losses (subject to any applicable limitations in this Article VIII) (a “Third Party Claim”), 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 Indemnified Party so long as such

-25-

counsel is reasonably acceptable to the Indemnified Party. If the Indemnifying Party elects to assume the defense of any such Third Party Claim, it shall within thirty (30) days notify the Indemnified Party in writing of its intent to do so. Subject to Section 8.03(c), the Indemnifying Party will have the right to settle or compromise or take any corrective or remedial action with respect to any such Third Party Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party. The Indemnified Party will be entitled, at its own cost, to participate with the Indemnifying Party in the defense of any such Third Party Claim, unless separate representation of the Indemnified Party by counsel is reasonably necessary to avoid a conflict of interest, in which case such representation shall be at the expense of the Indemnifying Party. If the Indemnifying Party assumes the defense of any such Third Party Claim but fails to diligently prosecute such Third Party Claim, or if the Indemnifying Party does not assume the defense of any such Third Party Claim, the Indemnified Party may assume control of such defense and in the event the Third Party Claim is determined to be a matter for which the Indemnifying Party is required to provide indemnification under the terms of this Article VIII, the Indemnifying Party will bear the reasonable costs and expenses of such defense (including fees and expenses of counsel).

(c) 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 or permit a default without the Indemnified Party’s prior written consent, in each case, that (i) does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a binding, irrevocable, written release of any Indemnified Party from all Liability, (ii) provides for any admission of Liability on the part of any Indemnified Party, (iii) requires an admission of guilt or wrongdoing on the part of any Indemnified Party or (iv) imposes any Liability or continuing obligation on or requires any payment from any Indemnified Party.

Section 8.04 Limitations.

(a) No Indemnifying Party shall have any Liability under Section 8.02(a)(i) or Section 8.02(b)(i) related to a representation or warranty other than a Fundamental Representation in respect of any individual claim involving Losses to any Indemnified Party of less than $100,000 (each, a “De Minimis Claim”), unless such individual claim is directly related to one or more other claims which in the aggregate involve Losses in excess of $100,000, in which case, the Indemnifying Party will have Liability for the full amount of such claims (subject to the other limitations contained in this Section 8.04) and such claims shall not

-26-

be considered De Minimis Claims (it being understood and agreed that notwithstanding anything in the foregoing to the contrary, solely for the purposes of this Section 8.04(a), all claims related to any fact or circumstance that causes any representation or warranty made in any particular Section of this Agreement to be inaccurate shall be deemed to be related to all other claims related to such fact or circumstance).

(b) No Buyer Indemnified Party shall be entitled to indemnification pursuant to Section 8.02(a)(i) related to a representation or warranty other than a Fundamental Representation unless the aggregate of all Losses claimed by the Buyer Indemnified Parties pursuant to such section that are not De Minimis Claims exceeds 1% of the Purchase Price (the “Claim Deductible”), in which case, subject to Section 8.04(d), the Sellers shall indemnify the Buyer Indemnified Party only for the Losses in excess of the Claim Deductible.

Section 12.11 Facsimiles; Electronic Transmission; Counterparts. This Agreement may be executed by facsimile or other electronic transmission (including scanned documents delivered by email) by any Party and such execution shall be deemed binding for all purposes hereof, without delivery of an original signature being thereafter required.

Section 12.15 Right to Rely. Following the Closing, any rights to indemnification, payment, reimbursement or other remedy based on representations, warranties, covenants or agreements in this Agreement or in any certificate delivered pursuant hereto shall not be affected by any investigation conducted at any time, or any knowledge acquired (or capable of being acquired) before the Closing. The waiver of any condition based on the accuracy of any representation or warranty, or in the performance of or compliance with, any such covenant or agreement, shall not affect the right to indemnification, payment, reimbursement, or any other remedy based on such representations, warranties, covenants or agreements.
