a. Claims by Non-Parties. After receipt by an Indemnified Party of notice of the commencement of any proceeding against it by a third party which is likely to give rise to Claims of An-Con Indemnitees or Claims of Stockholder Indemnitees, as the case may be, the Indemnified Party shall give prompt written notice ("Notice of Third Party Claim") to the Indemnifying Party slating the nature of such Claim, the amount thereof and a brief description of the facts and circumstances relating thereto, to the extent known.

The failure of an Indemnified Party to give such Notice of Third Party Claim to the Indemnifying Party or delay in giving such Notice of Third Party Claim, will not affect the validity or amount of the Claim and the indemnification obligations of the Indemnifying Party will remain in effect as to such Claim, unless such failure or delay prejudices the Indemnifying Party's defense of such Claim, in which case the Indemnifying Party will be relieved of its indemnification obligations to the extent that it has been so prejudiced. If within thirty (30) days after receiving such Notice of Third Party Claim, the Indemnifying Party advises the Indemnified Party that it will provide indemnification and assume the defense at its expense, then so long as such defense is being conducted, the Indemnified Party shall not settle or admit liability with respect to the Claim and shall provide the Indemnifying Party and defending counsel reasonable assistance in defending against the Claim.

	9

b. Claims by a Party.

If the Indemnified Party does not receive a written objection to the notice from the Indemnifying Party within thirty (30) days after the Indemnifying Party's receipt of such notice, the Claim shall be conclusively presumed to he a liability of the Indemnifying Party in an amount equal to such Claim. If within the aforesaid thirty (30) day period the Indemnified Party shall have received written objection to the notice (which written objection shall briefly describe, the basis of the objection to the notice or the amount thereof, all in good faith), then for a period of sixty (60) days after the receipt of such objection, the Parties shall attempt to settle the disputed Claim as between the Indemnified Party and Indemnifying Party.

4.4 Contribution. If the indemnification provided for in this Article 4 is held by a court of competent jurisdiction or arbitrator to be unavailable to an Indemnified Person with respect to any Claim herein, or, if the Indemnified Person or Indemnifying Person seeks contribution under the Securities Act, the Exchange Act or otherwise, then the Indemnifying Person, in lieu of Indemnifying such Indemnified Person hereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such Claim in such proportion as is appropriate to reflect the relative fault of the Indemnifying Person, on the one hand, and of the Indemnified Person, on the other hand, in connection with the statements or omissions or alleged statements or omissions that resulted in such Claims as well as any other relevant equitable consideration. The relative fault of the Indemnifying Person and of the Indemnified Person shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of the material fact or the omission or alleged omission to stale a material fact relates to information supplied by the Indemnifying Person or by the Indemnified Person, the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.
