Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Vesting of Performance Share Units ("PSUs") is contingent upon the reporting person's continued employment with Flagstone Reinsurance Holdings Limited (the "Company") and the Company meeting certain fully diluted return-on-equity ("FDROE") goals. Upon vesting, the PSU holder is entitled to receive a number of common shares of the Company (or the cash equivalent, at the election of the Company) equal to the product of the number of PSUs granted multiplied by a factor based on the Company's FDROE during the vesting period. The factor will range between 0.5 and 1.5, depending on the FDROE achieved during the vesting period.
(2)	These PSUs would vest, subject to the contingency described in note 1 above and the other terms and conditions of the Company's PSU Plan, on the date shown.
(3)	Assumes the Company would settle these PSUs within three months of the vesting date.
(4)	Represents the mid-point of the vesting range described in note 1 above for these PSUs.
(5)	These PSU grants are held through a trust for the benefit of others and Mr. Boisvert therefore disclaims beneficial ownership of these PSUs.
