Ambac Financial Group, Inc.

Mr. Callen�s written testimony will be made available on the Company�s website at the start of the event. Mr. Callen will note that the challenge facing Ambac is not one of meeting current obligations, but rather the need to achieve ratings stability to support Ambac�s future business.

He will discuss the stability of Ambac�s financial position with over $14 billion in claims paying resources. Furthermore, he will assure all of Ambac�s stakeholders that the entire management team is committed to preserving the Company�s strong franchise and positioning it for stability and growth.
