This Agreement (this “Agreement”) is made and entered into as of March 28, 2016, by and between Ambac Financial Group, Inc. (the “Company”) and Evermore Global Advisors, LLC (the “Stockholder”) (the Company and Stockholder, each a “Party” to this Agreement, and collectively, the “Parties”).

WHEREAS, Stockholder has communicated with the Company concerning the affairs of the Company, including possible additions to the membership of its board of directors (the “Board”);

WHEREAS, the Company and the Stockholder each desire that the Company increase the size of the Board and add two new members (who shall also be added to the Board of Ambac Assurance Corp. following the 2016 Annual Meeting) and desire that such new members be nominated for election at the 2016 annual meeting of stockholders of the Company, including any adjournment or postponement thereof (the “2016 Annual Meeting”);

WHEREAS, the Company and the Stockholder have each determined to come to agreement with respect to the foregoing and certain other matters, as provided in this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Parties, intending to be legally bound hereby, agree as follows:

1.Board Matters; Board Appointments; 2016 Annual Meeting.

(a)    Effective as of the execution of this Agreement, the Stockholder on behalf of itself and its Affiliates hereby agrees that it shall not, and that it and any of its Affiliates shall not (and shall use reasonable best efforts to cause its Associates not to), (i) nominate or recommend for nomination any person for election at the 2016 Annual Meeting, directly or indirectly, (ii) submit any proposal for consideration at, or bring any other business before, the 2016 Annual Meeting, directly or indirectly, (iii) initiate, encourage or participate in any “withhold” or similar campaign with respect to the 2016 Annual Meeting, directly or indirectly, or (iv) publicly or privately encourage or support any other stockholder to take, or support in the taking of, any of the actions or matters described in this Section 1(a).

(b)    The Board and all applicable committees of the Board shall promptly take all necessary actions, pursuant to the Bylaws so that (i) the Board shall be increased in size to eight members (from six), effective as of March 28, 2016 through the time that is immediately prior to the election of directors at the 2016 Annual Meeting, and then shall be reduced in size to six directors as of the election of directors at the 2016 Annual Meeting, it being understood that there shall be only six directors to be elected at the 2016 Annual Meeting; (ii) Ian Haft and David Herzog (the “Independent Nominees”), who have consented to such appointment and agreed to serve on the Board, shall be appointed to the Board to fill the resulting vacancies from the increase of the size of the Board, effective March 28, 2016; (iii) the Board shall nominate each of the Independent Nominees, along with Alexander Greene, C. James Prieur, Jeffrey Stein and Nader Tavakoli (collectively, the “2016 Board Nominees”) as directors for election to the Board at the 2016 Annual Meeting; (iv) at the 2016 Annual Meeting, two (2) of the directors serving on the Board on the date hereof (being Eugene Bullis and Victor Mandel) shall not stand for re-election and (v) the Company shall recommend, support and solicit proxies at the 2016 Annual Meeting for each of the 2016 Board Nominees; provided that the Company will use reasonable best efforts to recommend, support and solicit proxies in favor of the election of the Independent Nominees to the Board at the 2016 Annual Meeting (including recommending that the Company’s shareholders vote in favor of the Independent Nominees for election in a manner no less rigorous and favorable than the manner in which the Company recommends, support and solicits proxies in

favor of the election of the other 2016 Board Nominees in the aggregate). After the 2016 Annual Meeting and through the completion of the 2017 annual meeting of shareholders (the “2017 Annual Meeting”), the Board shall not increase the size of the Board to more than six directors other than by unanimous vote of the directors then in office.

(c)    From and after the 2016 Annual Meeting, the Independent Nominees shall serve on the board of directors of Ambac Assurance Corp., so long as such individuals serve on the Board.

(d)     Provided the obligations in Section 1(e) are in full force and effect, the Stockholder agrees to appear in person or by proxy at the 2016 Annual Meeting and to vote, or cause to be voted, all shares of shares of Common Stock beneficially owned by (x) the Stockholder or any of its Affiliates as of March 29, 2016 (the “Record Date”) and (y) all other shares over which such person has voting power at the 2016 Annual Meeting (i) in favor of the 2016 Board Nominees, (ii) in favor of the Company’s “say-on-pay” proposal, and (iii) in favor of the ratification of the Company’s auditors.

(e)     From the date hereof through the close of business on the date on which the 2016 Annual Meeting is completed (including any adjournments or postponements thereof), the Stockholder agrees that neither it nor any of its Affiliates will (and it shall use reasonable best efforts to cause its Associates not to), directly or indirectly, in any manner (whether through third parties or otherwise), other than, in each of cases (i) – (v), in support of and in favor of the election of all of the 2016 Board Nominees and the other matters referred to in Section 1(d):

(i)    solicit proxies or written consents of stockholders or conduct any other type of referendum (binding or non-binding) with respect to, or from the holders of, the Common Stock, or become a “participant” (as such term is defined in Instruction 3 to Item 4 of Schedule 14A promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), in or assist any person not a party to this Agreement (a “Third Party”) in any “solicitation” of any proxy, consent or other authority (as such terms are defined under the Exchange Act) to vote any shares of the Common Stock (other than such encouragement, advice or influence that is consistent with Company management’s recommendation in connection with such matter);

(ii)    advise, encourage, support or influence any person with respect to the voting of any securities of the Company at the 2016 Annual Meeting or special meeting of stockholders, or seek to do so (other than such encouragement, advice or influence that is consistent with the Company’s recommendation in connection with such matter);

(iv)    other than as provided in this Agreement, seek, alone or in concert with others, representation on the Board;

(v)    seek or request permission to do any of the foregoing, make any request to amend, waive or terminate any provision of this Section 1 (including, without limitation, this Section 1(e)), or make or seek permission to make any public announcement with respect to any of the foregoing;

(vi)    otherwise act, alone or in concert with others to make or cause to be made any statement disparaging of the Company, its directors or management including: (i) in any document or report filed with or furnished to the SEC or any other governmental agency, (ii) in any press release or other publicly available format, or (iii) to any analyst, journalist or member of the media (including without limitation, in a television, radio, newspaper or magazine interview), or otherwise (it being agreed that the prosecution in good faith of litigation asserting that the Company has breached its obligations under this Agreement, in and of itself, shall not constitute a

violation of this clause (vi) to the extent it is necessary in such litigation to describe the facts underlying the asserted breach).

The Stockholder further represents and warrants that, as of the date of this Agreement, the Stockholder has no current intention to transfer or dispose of, or engage in any trading in or with respect to, any Covered Shares.
