As the general partner, Trident GP holds voting and investment power with respect to the securities of the Company that are, or may be deemed to be, beneficially owned by Trident II. The manager of Trident II is Stone Point Capital LLC ("Stone Point"), and the members of Stone Point are Charles A. Davis, Meryl D. Hartzband, James D. Carey, Nicolas D. Zerbib and David J. Wermuth. In its role as manager, Stone Point has delegated authority to exercise voting rights of common shares on behalf of Trident II but does not have any power with respect to disposition of common shares held by Trident II. For any portfolio investment where Trident II controls 10% or more of the voting power of such portfolio company, Stone Point does not have discretion to exercise voting rights on behalf of Trident II without first receiving direction from the Investment Committee of Trident GP or a majority of the general partners of Trident GP. The general partners of Trident GP are four single member limited liability companies that are owned by individuals who are members of Stone Point(Messrs. Davis, Carey and Wermuth and Ms. Hartzband). Each of the single member limited liability companies that is a general partner of Trident GP has disclaimed beneficial ownership of the common shares and warrants that are, or may be deemed to be, beneficially owned by Trident II, except to the extent of their individual pecuniary interest therein. Stone Point also has disclaimed beneficial ownership of the common shares and warrants that are, or may be deemed to be, beneficially owned by Trident II. This report shall not be construed as an admission that the Reporting Persons are the beneficial owners of such securities for any purpose. Marsh & McLennan Capital Professionals Fund, L.P. ("Trident PF") and Marsh & McLennan Employees' Securities Company, L.P. ("Trident ESC") have agreed with Trident II that (i) Trident ESC will divest its holdings in the Company only in parallel with Trident II, (ii) Trident PF will not dispose of its holdings in the Company before Trident II disposes of its interest, and (iii) to the extent that Trident PF elects to divest of its interest in the Company at the same time as Trident II, Trident PF will divest its holdings in the Company in parallel with Trident II. As a result of this agreement, Trident II may be deemed to beneficially own 109,133 common shares directly held by Trident PF and Trident ESC, and Trident PF and Trident ESC may be deemed to beneficially own 2,839,897 common shares directly held by Trident II. Trident II disclaims beneficial ownership of the common shares that are, or may be deemed to be, beneficially owned by Trident PF and Trident ESC, and Trident PF and Trident ESC each disclaims beneficial ownership of the common shares that are, or may be deemed to be, beneficially owned by Trident II. Trident PF and Trident ESC are not affiliated and each disclaims beneficial ownership of the common shares and warrants that are, or may be deemed to be, benefically owned by the other. The sole general partner of Trident PF is a company controlled by individuals who are members of Stone Point. The sole general partner of Trident ESC is a company that is a wholly-owned subsidiary of Marsh & McLennan Companies, Inc. Stone Point has been granted a limited power of attorney by the sole general partner of Trident ESC which, among other things, gives Stone Point authority to execute this filing on behalf of Trident ESC.
