As of December 31, 2007, the Reporting Persons beneficially owned an aggregate of 15,842,073 shares, or 18.6%, of the Common Stock, as set forth in Items 7 through 13 of each of the cover pages of this Schedule 13D.   


E. Daniel James, a Director of Flagstone, is also a Managing Director of LBI and a senior manager of Lehman Brothers Merchant Banking Group.  In his capacity as director, he will participate, and have the opportunity to vote on matters that are presented to the board of directors of Flagstone, including sales of assets, extraordinary corporate transactions, and changes to Flagstone’s capitalization, business or corporate structure.  As part of their compensation for serving as directors, Mr. James, and the other directors of Flagstone, have received, and it is expected that they will in the future from time to time receive, shares of Common Stock, RSUs or options to purchase shares of Common Stock.  Under the terms of Mr. James’ employment with LBI, he is required to surrender to LBI any compensation (including Common Stock, RSUs and options) received in his capacity as a director of Flagstone.    


At the time of the IPO, Mr. James had been granted 5,833 RSUs, and on May 10, 2007, Flagstone granted to Mr. James an additional 6,240 RSUs.  The 12,073 shares of Common Stock underlying the RSUs are included in the total number of shares of Common Stock reported herein.  Mr. James disclaims beneficial ownership of those and all other shares of the Common Stock beneficially owned by the Reporting Persons.


LBI acted as an underwriter and lead manager of the IPO.  LBI also provided additional investment banking services to Flagstone in connection with its initial private placement.  Pursuant to the underwriting agreement, LBI received customary and usual compensation, indemnification and contribution from Flagstone as an underwriter and lead manager of the IPO.


Flagstone controls Mont Fort Re Ltd., which raises capital from investors through offerings of its preferred shares and uses the proceeds of those offerings to underwrite reinsurance ceded to it by Flagstone.  This type of arrangement is often referred to as a “sidecar.”  LB I Group has invested $50.0 million in a segregated account, or “cell,” of Mont Fort Re Ltd., called Mont Fort ILW Cell, and owns 50.0 million, or 90.9%, of the Mont Fort ILW Cell preferred shares.  LB I Group has also invested $55.0 million in Mont Fort ILW 2 Cell and owns 55.0 million, or 100.0%, of the Mont Fort ILW 2 Cell preferred shares. Flagstone owns all of the common shares of Mont Fort Re Ltd. and has 100% control of its board of directors.  The holders of preferred shares relating to cells of Mont Fort have no right to elect directors.  For additional information about LB I Group’s investments in the cells of Mont Fort Re Ltd., see “Business-Mont Fort” in the Prospectus filed by Flagstone with the Securities Exchange Commission on March 30, 2007.


The Reporting Persons intend to continually evaluate the business, prospects and financial condition of Flagstone, the market for the Common Stock, other opportunities available to the Reporting Persons, general economic conditions, money and stock market conditions and other factors and future developments which the Reporting Persons may deem relevant from time to time.  Depending on such factors, the Reporting Persons may decide to sell all or part of the shares of Common Stock they hold or purchase additional shares. Any such acquisition or disposition of Common Stock may be effected through open market or privately negotiated transactions, or otherwise.

APPENDIX B



From time to time, the firm and its employees are the subject of inquiries and investigations conducted by regulatory authorities, including but not limited to the SEC, MSRB, NASD, NYSE and state securities regulators.  Lehman Brothers routinely cooperates freely with such investigations.  The Firm is also involved, from time to time, in civil legal proceedings and arbitration proceedings concerning matters arising in connection with the conduct of this business.  Although there can be no assurance as to the ultimate outcome, the firm has denied, or believes it has meritorious defenses and will deny, liability in all significant cases pending against it, and intends to defend actively each such case.  All material proceedings in which there has been a final determination against Lehman Brothers, and all material litigations involving Lehman Brothers, have been reported on the Firm’s Annual Report on Form 10-K, Quarterly Report on Form 10-Q or the Firm’s Form BD, each of which is on file with the Securities and Exchange Commission.
