              OF DIRECTORS; APPOINTMENT OF CERTAIN OFFICERS; COMPENSATORY
              ARRANGEMENTS OF CERTAIN OFFICERS.

         On and effective September 5, 2007, the Board of Directors of Flagstone
Reinsurance Holdings Limited (the "Company") appointed Peter Watson to its Board
of Directors (the "Board"). The appointment of Mr. Watson to the Board fills the
vacancy created by the retirement from the Board of Nicholas Brumm at the end of
his term on July 20, 2007. Mr. Watson is being appointed to Class C, the term of
which runs through the Company's 2010 annual general meeting of shareholders,
and has been determined to be independent by the Board under the independence
requirements of the New York Stock Exchange and the audit committee independence
rules of the U. S. Securities and Exchange Commission. The Board also appointed
Mr. Watson to serve on the Company's Audit Committee.

         Mr. Watson, age 65, is Vice Chairman, President and CEO of Attorney's
Liability Assurance Society (Bermuda) Ltd. ("ALAS Ltd."), a Bermuda-based mutual
insurance company. Prior to joining ALAS Ltd., Mr. Watson was a partner at Price
Waterhouse.

         Mr. Watson's compensation as a director will be consistent with the
compensation of the Company's other non-employee directors. As a Company
director, Mr. Watson will receive:

         (i)    Annual director fees of $75,000, with approximately $35,000 of
                the annual director fee provided in the form of restricted stock
                units ("RSUs"), both amounts prorated at 25% for the portion of
                the current annual period which he will serve on the Board (such
                that for 2007 Mr. Watson's director fees awarded in cash will be
                $10,000 and director fees awarded in RSUs will have, at the time
                of the grant, an aggregate fair market value of $8,750);

         (ii)   Annual committee membership fee of $3,000 cash awarded on a
                prorated basis (such that Mr. Watson's total cash committee
                membership fees for 2007 will be $750); and

         (iii)  2007 per meeting fee of $2,000 cash for in-person participation
                and $1,000 for telephonic participation.

         The RSUs granted to Mr. Watson will be made pursuant to the Amended and
Restated Flagstone Reinsurance Holdings Limited Restricted Share Unit Plan and
the form of grant certificate which was previously filed as Exhibit 10.4 to the
Company's Form S-1. In accordance with the Company's policies, the grant of RSUs
to Mr. Watson will be made on the effective date of his appointment as a
director and will vest upon grant.

            A copy of the press release dated September 5, 2007 announcing Mr.
Watson's election is attached as Exhibit 99.1 to this Current Report on Form
8-K.
