WHEREAS, the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby are required in connection with the Merger Agreement,

Indemnitor represents and warrants to Indemnitees that Schedule A hereto contains a complete and accurate listing of all Liabilities of AMIB as of the Effective Time as defined in the Merger Agreement. Other than as set forth on Schedule A hereto, as of the Effective Time, AMIB is not liable for any other liability, debt, obligation, deficiency, tax, penalty, fine, claim, cause of action or other loss, cost or expense of any kind or nature whatsoever, whether asserted or unasserted, absolute or contingent, accrued or unaccrued, liquidated or unliquidated, and whether due or to become due.

2.                  Indemnification.

To the extent that any of the Liabilities of AMIB, whether set forth on Schedule A or otherwise, are, by their terms, convertible into any capital stock of AMIB, Indemnitor shall assist with and facilitate the written modification of the terms of such Liabilities to remove any such right to conversion. In addition to the indemnification provided under Section 2, above, Indemnitor shall defend and indemnify the Indemnitees against any claim by any person or entity that their Liability is or was convertible to capital stock of AMIB.

The Releasors irrevocably agree to refrain from instituting any suit, action or proceeding of any kind, in any court or before any tribunal, against any Released Party based upon, arising out of, or relating to any Released Claim, participating, assisting or cooperating in any such suit, action or proceeding or encouraging or soliciting any third party to institute any such suit, action or proceeding.
