As authorized by Section 145 of the General Corporation Law of Delaware, each director and officer of Ambac may be indemnified by Ambac against expenses (including attorneys' fees, judgments, fines and amounts paid in settlement) actually and reasonably incurred by such director or officer in connection with the defense or settlement of any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, in which he is involved by reason of the fact that he is or was a director or officer of Ambac if he acted in good faith and in a manner that he reasonably believed to be in or not opposed to the best interests of Ambac, and, with respect to any criminal action or proceeding, if he had no reasonable cause to believe that his conduct was unlawful.

In addition, Ambac maintains a Directors' and Officers' liability insurance policy.

Item 9. Undertakings. (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; (ii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that the undertakings set forth in paragraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by Ambac pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby further undertakes that, for purposes of determining any liability under the Securities Act, each filing of Ambac's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of Ambac pursuant to the foregoing provisions, or otherwise, Ambac has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Ambac of expenses incurred or paid by a director, officer or controlling person of Ambac in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, Ambac will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
