     6.1 Survival.

          (a) Except as set forth in Section 6.1(b), all representations and warranties contained in this Agreement shall survive the Closing for a period of one (1) year.

          (b) The representations and warranties of CHAD contained in Sections 4.1 (Organization and Authority of CHAD), 4.2 (Corporate Power and Authority; Due Authorization), 4.3 (Title to Purchased Assets), 4.7 (Tax Liens), and 4.15 (Broker’s Fee), and the representations and warranties of Purchaser contained in Sections 5.1 (Organization and Authority of Purchaser), 5.2 (Power and Authority; Due Authorization) and 5.4 (Broker’s Fees) shall survive the Closing indefinitely.

          (c) The covenants and agreements which by their terms do not contemplate performance after the Closing shall survive the Closing for a period of one (1) year. The covenants and agreements which by their terms contemplate performance after the Closing Date shall survive the Closing for a period of three (3) years, or until the expiration of the applicable statute of limitation, whichever is longer.

          (d) The period for which a representation or warranty, covenant or agreement survives the Closing is referred to herein as the “Applicable Survival Period.” In the event notice of claim for indemnification under Section 6.2 or 6.3 is given within the Applicable Survival Period, the representation or warranty, covenant or agreement that is the subject of such indemnification claim (whether or not formal legal action shall have been commenced based upon such claim) shall survive with respect to such claim until such claim is finally resolved. The Indemnitor shall indemnify the Indemnitee for all Losses (subject to the limitations set forth herein, if applicable) that the Indemnitee may incur in respect of such claim, regardless of when incurred.

     6.2 Indemnification by CHAD.

          (a) CHAD shall indemnify and defend Purchaser and its affiliates and their respective stockholders, members, managers, officers, directors, employees, agents, successors and assigns (the “Purchaser Indemnitees”) against, and shall hold them harmless from, any and all losses, damages, claims (including third party claims), expenses (including reasonable legal, consultant, accounting and other professional fees, and reasonable fees and costs incurred in enforcing rights under this Section 6.2) (collectively, “Losses”) resulting from, arising out of, or incurred by any Purchaser Indemnitee in connection with, or otherwise with respect to:

               (i) any breach of the representations and warranties of CHAD contained in Sections 4.1, 4.2, 4.3, 4.7, and 4.15 and the covenants of CHAD contained in Sections 3.1, 3.2, 3.4, 3.5, 3.7, 3.8, 3.9 and 3.11;

               (ii) any Excluded Liability including any pre-Closing Liability, regardless of whether or not the Schedules discloses any such Excluded Liability;

               (iii) any fees, expenses or other payments incurred or owed by CHAD to any agent, broker, investment banker or other firm or person retained or employed by it in connection with the transactions contemplated by this Agreement and the CHAD Transaction Documents; and

               (iv) fraudulent transfer laws or the failure to comply with any bulk sales laws and similar laws.

     6.3 Indemnification by Purchaser. Purchaser shall indemnify and defend CHAD and its managers, officers, directors, employees, agents, successors and assigns (the “CHAD Indemnitees”) against, and shall hold them harmless from, any and all losses resulting from, arising out of, or incurred by any CHAD Indemnitee in connection with, or otherwise with respect to the operation of the Business after the Closing Date.

     6.4 Third Party Claims. In the event that a Purchaser Indemnitee or CHAD Indemnitee (each an “Indemnitee”) receives notice of the assertion of any claim or the commencement of any action by a third party in respect of which indemnity may be sought under the provisions of Section 6.2 or 6.3 (“Third Party Claim”), the Indemnitee shall promptly notify the indemnifying party (“Indemnitor”) in writing of such Third Party Claim (“Notice of Claim”). Failure or delay in notifying the Indemnitor will not relieve the Indemnitor of any Liability it may have to the Indemnitee, except and only to the extent that such failure or delay causes actual harm to the Indemnitor with respect to such Third Party Claim. The Notice of Claim shall set forth the amount, if known, or, if not known, an estimate of the foreseeable maximum amount of claimed Losses (which estimate shall not be conclusive of the final amount of such losses) and a description of the basis for such Third Party Claim.

     6.5 Indemnification Procedures for Non-Third Party Claims. In the event of a claim that does not involve a Third Party Claim being asserted against it, the Indemnitee shall send a Notice of Claim to the Indemnitor. The Notice of Claim shall set forth the amount, if known, or, if not known, an estimate of the foreseeable maximum amount of claimed Losses (which estimate shall not be conclusive of the final amount of such Losses) and a description of the basis for such claim. The Indemnitor will have 30 days from receipt of such Notice of Claim to dispute the claim and will reasonably cooperate and assist the Indemnitee in determining the validity of the claim for indemnity. If the Indemnitor does not give notice to the Indemnitee that it disputes such claim within 30 days after its receipt of the Notice of Claim, the claim specified in such Notice of Claim will be conclusively deemed a Loss subject to indemnification hereunder.

     6.6 Sole and Exclusive Remedy . The indemnification rights of the parties under this Article VI are the sole and exclusive remedy for any misrepresentation, breach of warranty or failure to fulfill any agreement or covenant hereunder on the part of any party hereto, and the parties expressly agree that they shall have no right to seek specific performance, rescission or restitution based on an alleged violation of this Agreement . Notwithstanding the foregoing, nothing herein shall limit the right of either party to bring a legal action against the other party for fraudulent statements or conduct in connection with this Agreement or the transactions contemplated thereby.
