Buyer shall indemnify and hold harmless Sellers and the Representative from, against and in respect of Losses incurred as a result of any of the following: (i) any breach or default in performance by Buyer of any covenant or agreement of Buyer contained in this Agreement or any breach or default in performance by the Company of any covenant or agreement made by the Company in this Agreement that is to be performed after the Closing including, without limitation, Section 5.5, (ii) any breach of, or inaccuracy in, any representation or warranty made by the Buyer in this Agreement or any other Transaction Agreement, and (iii) any claim that arises with respect to the conduct of the Business on or after the Closing.

          6.2. Seller’s Indemnification. Subject to the limitations set forth in this Section 6 and the Indemnity and Non-Solicitation Agreement, from and after the Closing, each of the Sellers, shall severally, but not jointly (except in the case of the second sentence of Section 3.01 of the Indemnity and Non-Solicitation Agreement), indemnify and hold harmless the Buyer from, against and in respect of Losses incurred as a result of any of the following: (i) any breach or default in performance by the Representative or the Sellers of any covenant or agreement contained in this Agreement, (ii) any breach of, or inaccuracy in, any representation or warranty made by the Company or the Representative in this Agreement, (iii) any charges, complaints, actions, suits, proceedings, hearings, investigations, claims or demands relating to the Company or

-12-

the Business existing as of the Closing or arising from conduct of the Company prior to the Closing, (iv) any Tax liabilities or obligations of the Company arising out of the operation of the Business prior to the Closing, (v) the transfer or purported transfer of the Membership Interests, and (vi) any claims against, or liabilities or obligations of, the Company with respect to the Company Benefits. Any indemnification to which the Buyer is entitled pursuant to this Section 6.2 shall be governed by the terms of the Indemnity and Non-Solicitation Agreement and Escrow Agreement.

          6.3. Monetary Limitations.

               (a) Sellers shall have no obligation to indemnify Buyer pursuant to this Section 6 in respect of a claim for indemnification for breaches set forth in Section 6.2(i) or Section 6.2(ii) of this Agreement (other than indemnification obligations in connection with breaches of Sections 2.5(c) or 5.5) unless and until the aggregate of all individual Losses incurred or sustained by Buyer with respect to which Buyer is entitled to indemnification under such Sections exceeds $150,000 (the “Indemnification Threshold”), and the Buyer shall be entitled to recover for Losses only to the extent such Losses exceed the Indemnification Threshold. Notwithstanding anything to the contrary herein, the aggregate liability of the Sellers for (a) Losses under this Section 6 (other than Losses in connection with breaches of Section 2.5(c) or 5.5) shall not exceed $2,530,000, and (b) Losses under this Section 6 in connection with breaches of Sections 2.5(c) and 5.5 shall not exceed an aggregate of $1,000,000 less the aggregate amount of payments received by Buyer for Scheduled Receivables.

               (b) If the Escrow Agent pays Buyer for a claim and subsequently insurance proceeds in respect of such claim are collected by Buyer or the Company, then Buyer shall promptly remit the insurance proceeds, to the extent of any payments by the Escrow Agent in connection with such claim, (i) to the Escrow Agent if the Escrow Agreement is then in effect, and (ii) to the Representative on behalf of the Sellers if the Escrow Agreement is not then in effect.

          6.4. Manner of Indemnification. The Buyer may make a claim against each of the Sellers, severally (but not jointly) in proportion to their pro rata ownership of Membership Interests as of the Closing, by providing the Representative and, if Buyer is seeking indemnification from the amounts held in escrow pursuant to the Escrow Agreement, the Escrow Agent (if the Escrow Agreement is then in effect) with written notice. Buyer agrees to seek indemnification for any claims pursuant to this Section 6 (other than claims in connection with breaches of Sections 2.5(c) or 5.5) by first seeking such indemnification from the amounts held in escrow pursuant to the Escrow Agreement.

          6.5. Time Limitations. No claim for indemnification against the Sellers for breaches of a representation or warranty pursuant to this Section 6 shall be valid unless notice thereof describing such claim with reasonable specificity (in light of the facts then known) is delivered to the Representative on or prior to the date that the representation or warranty giving rise to such breach expires in accordance with Section 6.9.

-13-

          6.6. Purchase Price Adjustment. Any indemnification payment made by the Sellers pursuant to this Section 6 shall be treated by the Sellers as an adjustment to the Purchase Price for Tax purposes, unless otherwise required pursuant to a final determination, within the meaning of Section 1313 of the Code.

          6.7. Exclusive Remedy. The indemnification provisions set forth in the Indemnity and Non-Solicitation Agreement and this Section 6 shall constitute the sole and exclusive remedy of Buyer, Sellers, and the Representative for Losses arising out of, resulting from or incurred in connection with the breach of any representation, warranty or agreement made by the parties in this Agreement; provided, however, that this exclusive remedy for Losses does not preclude a party from bringing an action (i) for specific performance or another equitable remedy to require a party to perform its obligations under this Agreement or (ii) for fraud or intentional misrepresentation. Without limiting the generality of the preceding sentence, no legal action sounding in tort, statute or strict liability (other than for fraud or intentional misrepresentation) may be maintained by any party.

          6.8. Cooperation. Buyer and the Company shall use commercially reasonable efforts to cooperate with the Representative to minimize any potential or actual Losses incurred pursuant to Section 6.2.

          6.9. Survival of Representations and Warranties. All representations and warranties in this Agreement shall expire on the first anniversary of the Closing Date, except for (i) the representations and warranties set forth in Sections 3.1 (Authority) and 3.2 (Title to Membership Interests) which shall survive the Closing without limitation, and (ii) the representations set forth in Sections 2.13 (ERISA Matters) and Section 2.16 (Taxes) which shall survive until the applicable statute of limitations with respect to such claims expires. If a party delivers to another party, before expiration of a representation or warranty, a notice of breach of such representation or warranty, then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of any claims arising from or relating to the matter covered by such notice.
