SECTION 7

The representations and warranties contained in this Agreement shall survive the Closing and remain in full force and effect until the [c.i.]; provided, however, that if notice of any claim for [c.i.] shall have been given prior to the [c.i.], the relevant representations and warranties shall survive for purposes of such claim until such time [c.i.].

7.2 Indemnification by Seller. Seller shall indemnify Purchaser and its Affiliates and their respective, Representatives against, and hold them harmless from, any Losses, to the extent arising from:

7.2.1 any breach of any representation or warranty of Seller contained in this Agreement;

7.2.5 the use or misuse of any of the Purchased Assets before the Closing Date.

EXECUTION COPY

7.3 Indemnification by Purchaser. Purchaser shall indemnify Seller and its Affiliates and their respective Representatives against, and agrees to hold them harmless from, any Losses, to the extent arising from:

7.3.1 any breach of any representation or warranty of Purchaser contained in this Agreement;

7.3.2 any breach of any covenant of Purchaser contained in this Agreement;

7.3.3 any fees, expenses or other payments incurred or owed by Purchaser to any Persons retained or employed by it in connection with the Transactions;

7.3.4 the manufacture, sale, purchase, use, or ingestion by any Third Party of any product sold by or on behalf of the Purchaser under any of the Purchased Assets after the Closing Date.

7.3.5 the use or misuse of any of the Purchased Assets after the Closing Date.

7.4 Procedures. In order for a Party (the “Indemnified Party”) to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim made by any Person against the Indemnified Party (a “Third Party Claim”), such Indemnified Party must notify the indemnifying party (the “Indemnifying Party”) in writing (and in reasonable detail) of the Third Party Claim within [c.i.] after receipt by such Indemnified Party of notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided under this Agreement except to the extent the Indemnifying Party shall have been [c.i.] as a result of such failure. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within [c.i.] after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.

7.4.1 If a Third Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof with counsel selected by the Indemnifying Party and satisfactory to the Indemnified Party. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, [c.i.], separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party shall control such defense. The Indemnifying Party shall be liable for the [c.i.] employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof. If the Indemnifying Party chooses to defend or prosecute a Third Party Claim, all Indemnified Parties shall cooperate in the defense or prosecution thereof. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such Third Party Claim, and making Representatives available on a mutually convenient basis to provide additional information and explanation of any material provided under this Agreement or other matters reasonably related to such Third Party

EXECUTION COPY

Claim. Whether or not the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld). If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of a Third Party Claim that the Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the Losses in connection with such Third Party Claim, which releases the Indemnified Party completely in connection with such Third Party Claim and that would not otherwise materially adversely affect the Indemnified Party. Notwithstanding the foregoing, the Indemnified Party shall not unreasonably withhold its consent to a settlement that the Indemnifying Party may recommend provided the Indemnifying Party assumes the defense of a Third Party Claim.

7.4.2 In the event any Indemnified Party should have a claim against any Indemnifying Party under Section 7.2 or 7.3 that does not involve a Third Party Claim being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver notice of such claim with reasonable promptness to the Indemnifying Party, but in any event not later than [c.i.] after the Indemnified Party determines that it has or is reasonably likely to have a claim to indemnification under this Agreement, stating the amount of Loss, if known, and method of computation thereof, and containing a specific reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises. The failure by any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any indemnification obligation that it may have to such Indemnified Party under Section 7.2 or 7.3, as applicable, except to the extent that the Indemnifying Party is a[c.i.] by such failure. If the Indemnifying Party disputes that it has an indemnification obligation with respect to such claim, the Indemnifying Party shall deliver notice of such dispute with reasonable promptness and the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute for a period of [c.i.] following the receipt by the Indemnified Party of such dispute notice. If the Indemnified Party and the Indemnifying Party have not resolved such dispute during such time period through good faith negotiations, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction or other mutually agreeable non-judicial dispute resolution mechanism.

7.5 Limitation on Liability. EXCEPT WITH RESPECT TO THIRD PARTY CLAIMS, THE INDEMNIFICATION OBLIGATIONS OF THE PARTIES SHALL NOT EXTEND TO INDIRECT, INCIDENTAL, PUNITIVE OR CONSEQUENTIAL DAMAGES, INCLUDING BUSINESS INTERRUPTION, LOST PROFITS, LOSS OF USE, DAMAGE TO GOODWILL OR LOSS OF PRODUCTS, EXCEPT TO THE EXTENT THAT THE INDEMNIFIED PARTY CAN PROVE FRAUD.
