(a) a warranty or representation by NAI as to the validity, enforceability, or scope of any right included in the Licensed Rights or Trademark Rights;

(b) a warranty or representation by NAI that any Licensed Products made or sold under any license or sublicense granted in accordance with this Agreement will not infringe, directly or indirectly, any patent or other intellectual property rights of any third party under the laws of the United States or any other jurisdiction; or

8.2 NAI will use reasonable efforts to notify CSI promptly of any claim for which NAI believes it is entitled to indemnification under this Section 8 and which NAI desires CSI to defend. However, NAI’s failure to provide such notice or delay in providing such notice will relieve CSI of its obligations under this Section 8 only if and to the extent such delay or failure materially prejudices CSI’s ability to defend such claim. NAI will have the right to participate in the defense of such claim with its own counsel. No settlement of a claim will be binding on NAI without NAI’s prior written consent.

8.3 In no event shall NAI be liable for any indirect, special, incidental or consequential damages (including, without limitation, damages for loss of profits or expected savings or other economic losses, or for injury to persons or property) arising out of or in connection with this Agreement or its subject matter regardless of whether NAI knows or should know of the possibility of such damages. NAI’s aggregate liability for all damages of any kind relating to this Agreement or its subject matter shall not exceed the amount of Sublicense Fees paid by CSI to NAI under this Agreement. The foregoing exclusions and limitations shall apply to all claims and actions of any kind, whether based on contract, tort (including but not limited to negligence), or any other grounds.

9.1 CSI shall, at its sole cost and expense, procure and maintain comprehensive or commercial general liability insurance in amounts not less than $2,000,000 per incident and $3,000,000 annual aggregate naming NAI as an additional insured.

Without limiting the generality of the foregoing, within thirty (30) days after the Effective Date, CSI shall pay to NAI the Sublicense Fees on any such sales by CSI of Raw Materials from March 2007 until the Effective Date as if such sales had occurred during the term of this Agreement.

10.3 Either party may terminate this Agreement prior to the end of the term stated in Section 10.1 after notice to the other party but only if such other party materially fails to comply with any term or covenant in this Agreement and such failure continues for more than thirty (30) days after written notice of such breach from the non-breaching party; provided, however that if such failure cannot be reasonably cured within thirty (30) days the non-breaching party may terminate this Agreement if the breaching party fails to commence such cure within thirty (30) days and fails to thereafter diligently prosecute such cure to completion.
